    FIELD OF THE INVENTION
    [001] The present invention relates to a device for skin treatment in terms of cleaning, exfoliating and massaging the skin of a user. HISTORY OF THE INVENTION
    [002] It is known to provide devices for cleansing, exfoliating and massaging the skin. These devices comprise a brush, or other type of skin care part, which is configured to rotate. In use, the rotating brush is placed against the skin and the rotating movement stimulates microcirculation, removing dirt and dead skin cells thereby leaving the user's skin feeling soft and clean.
    [003] It is also known to provide a device for skin treatment in which the brush is configured to vibrate in addition to rotating, which improves the feeling of clean and treated skin. However, the speed of rotation movement and frequency of vibration movement cannot be independently changed by the user and therefore a user cannot adjust the device to his personal preference. SUMMARY OF THE INVENTION
    [004] It is an object of the invention to provide a skin treatment device that substantially alleviates or overcomes the aforementioned problems.
    [005] According to the present invention, there is provided a device for the treatment of the skin comprising a casing, an axis located in the casing having a longitudinal axis and an end for receiving a part of the skin treatment, and a means of drive configured to make the shaft rotate about its longitudinal axis, and oscillate in a direction along the longitudinal axis, wherein the drive means comprises a rotational drive unit for rotating the shaft and an oscillation generator for oscillating the axis, the oscillation generator is located on the axis such that the axle is rotated relative to the oscillation generator, the oscillation generator comprises a solenoid and a flux set, and the flux set is movable along the axis in relation to the solenoid.
    [006] This arrangement provides the advantage that in use, when a skin treatment part is affixed to the end of the shaft, the skin treatment part moves substantially perpendicular to the skin which improves the cleaning and massaging effect on the skin. Furthermore, the oscillation generator is not coupled to the rotational drive unit and thus the oscillation movement can be controlled independently of the shaft rotation.
    [007] Preferably, the rotational drive unit and the oscillation generator are configured in such a way that the rotation speed and frequency of the axle oscillation can be changed independently from each other in response to a user input .
    [008] Advantageously, the user can therefore adjust the frequency and speed of rotation to his personal preference.
    [009] Preferably, the flux assembly comprises an internal and an external flux concentrator and a magnet located between them.
    [010] The arrangement of the flux assembly concentrates the magnetic forces emitted by the magnet.
    [011] In one embodiment, the outer flow concentrator is made of a base panel that has a peripheral side panel, and the inner flow concentrator is received within the peripheral side panel, the magnet is located between the inner flow concentrator and the base panel, and an opening is formed between the inner flow concentrator and the peripheral side panel for receiving the solenoid.
    [012] Conveniently, the device further comprises the first and second brackets that secure the shaft, the flow assembly being located on the shaft between the first and second brackets and the solenoid being affixed to one of the brackets.
    [013] Advantageously, the flux assembly is held between the first and second supports in such a way that it cannot accidentally fall off the axis.
    [014] Conveniently, the axis is held by the first and second supports such that the axis is rotated relative to the supports about the longitudinal axis, but prevented from moving along the longitudinal axis with respect to the fur. minus one of the supports.
    [015] This arrangement allows the axial movement of the flux set to be transferred to the shaft when the flux set affects at least one of the supports.
    [016] The axle may comprise a circumferential groove in which the one of the supports is located so as to prevent the axle from moving along the longitudinal axis in relation to the support which is located in the groove.
    [017] Advantageously, when the flux assembly affects the support located in the groove, the support is moved in an axial direction and transfers the axial movement to the shaft.
    [018] One of the supports can be formed with an e-clip that is located in the circumferential groove.
    [019] This provides the advantage that the axial movement of the flux assembly is transferred to the holder formed with an e-clip and when the e-clip is located in the groove the axial movement is transferred to the shaft.
    [020] Preferably, one of the supports is formed with a stop whose flux set affects when it oscillates.
    [021] When the stop receives the impact of the flow assembly, the wear of the support formed with the stop is advantageously reduced.
    [022] In one embodiment, the spring is located between the first or second support and the flux assembly so as to reduce the impact when the flux assembly oscillates.
    [023] This arrangement advantageously reduces the audible noise produced when the flux set affects the first or second supports.
    [024] The device further comprises a power source that feeds the drive means.
    [025] Advantageously, this arrangement allows a single energy source to power the drive means which reduces the size and weight of the device.
    [026] In one embodiment, the device further comprises an inverter to change the current supplied by the power source to alternating current.
    [027] This causes the polarity of the solenoid to change so that it alternates between being attracted and repelled by the magnet.
    [028] Conveniently, the device can comprise a frequency converter to change the frequency of alternating current.
    [029] Advantageously, the frequency converter is configured to change the frequency in response to a user input such that the intensity of the wobble motion of the shaft and thus the brush can be changed to a user's personal preference. .
    [030] These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described below. BRIEF DESCRIPTION OF THE DRAWINGS

    [037] Referring now to the drawings, a device 1 for treating the skin is shown in Figure 1. The device 1 comprises a housing 2 having a first manual region 4 which is suitable for being held by a user, and a second head region 5 configured to connect to a brush 3.
    [038] The first region 4 includes a battery 7. The battery 7 can be rechargeable. It should be appreciated that an alternative power source can be used, for example the device can be connected to a wall outlet in the electrical distribution network. The battery 7 supplies a drive means comprising an oscillation generator 26 and a rotational drive unit located in the second region 5. The oscillation generator 26 is configured to oscillate an axis 14 disposed in the housing along its longitudinal geometric axis, and the rotational drive unit is configured to rotate shaft 14 about its longitudinal axis. The housing 2 is further provided with an operating switch (not shown) for switching the device on/off and for switching the device into various oscillation and rotation operating modes as explained in more detail below.
    [039] The shaft 14 is configured to connect to the brush 3 and is disposed in the second region 5 of the casing 2. It is supported and supported by a frame 11. The frame 11 is best illustrated in Figure 3 and comprises a first and a second brackets referred to as a front and a rear bracket 12, 13 which are spaced apart so as to provide a space in the oscillation generator 26. The shaft 14 is configured to rotate relative to the front and rear brackets 12, 13 as it will become evident from the description below.
    [040] Axis 14 is shown in more detail in Figure 4, and is generally shaped like a rod and has a longitudinal geometric axis 'A'. Shaft 14 is preferably made of stainless steel and comprises a ribbed end 15 which is formed with protrusions 16 extending in the longitudinal direction 'A' of shaft 14. When the shaft is disposed in housing 2, the ribbed end 15 is projects out of the second region 5 of housing 2 where it connects into a corresponding recess 17 formed in brush 3 (see Figure 2). The recess 17 of the brush 3 is formed of plastic and the brush is affixed to the ribbed end 15 of the shaft 14 by snapping-in such that the plastic of the recess flows cold between the protrusions 16. The ribs 16 of the ribbed end 15 improves the connection between brush 3 and shaft 14 when they mechanically engage recess 17 of brush 3 in a rotational direction about the longitudinal axis 'A' of shaft 14. It should be understood that the present invention is not limited to a brush that is attached to the casing, when any part of the alternative skin treatment, such as a cotton pad or pad, can be attached to the ribbed end which has a cleansing, exfoliating or massaging effect.
    [041] A seal (not shown) is provided between shaft 14 and housing 2 near the ribbed end 15 so as to form a waterproof seal between said shaft 14 and housing 2...
    [042] At an opposite end 19 to the ribbed end 15, the shaft 14 is formed with a cut portion 18 along the axial direction such that the cross-sectional profile of the shaft relative to the longitudinal axis is 'D-shaped ', as can be seen from Figure 4. This end 19 is located in a corresponding center of a gear 20 (see Figures 2 and 3) that forms part of the rotational drive unit
    [043] The rotational drive unit comprises a motor 8 which is located in the housing 2 between the first and second regions 4, 5. The motor 8 has a motor shaft 9 as best seen in Figure 2, the motor shaft 9 it can be driven in two opposite rotational directions and at different rotational speeds. The rotational drive unit further comprises a gear train 21 which is connected to a motor shaft 9 of the motor 8. The rotational movement of the rotational drive unit is generated by the motor 8 which rotates the shaft of the motor 9. motor 9 in turn rotates gear train 21 including gear 20 which shaft 14 is connected such that shaft 14 itself rotates. This is not described in much detail as it is considered to be common general knowledge of a person skilled in the art. It should be appreciated that the gear train may comprise one or a plurality of gears depending on the arrangement of motor 8 and shaft 14.
    [044] As described above, axle 14 is held by front and rear supports 12, 13 of frame 11. Rear support 13 holds axle 14 in a region adjacent to a cut portion 18 such that the axle can rotate and moving in an axial direction with respect to said rear support 13. Shaft 14 is movable in an axial direction with respect to gear 20 in which it is located. The front support 12 is formed with an e-clip 23 (see Figure 3) which is located in a circumferential groove 24 (see Figure 4) formed in the shaft close to the ribbed end 15 such that the shaft 14 can rotate but is prevented from moving in an axial direction relative to the front support 12. In an alternative non-illustrated embodiment, the front support is not formed with an e-clip and the front support is configured to locate directly in the circumferential groove 24.
    [045] The front support 12 is flexibly connected to the frame 11 so as to allow the axle to move between the forward and backward position when the axle oscillates along its longitudinal direction.
    [046] Located between the front and rear supports 12, 13 of the frame 11 is a flux assembly 25 that forms part of the oscillation generator 26. The flux assembly 25 is formed in a bushing 27 that surrounds the shaft 14. bushing 27 and the corresponding bearing surface of shaft 14 allow shaft 14 to rotate freely relative to flow assembly 25.
    [047] The flow set 25 will now be described with reference to Figures 3 and 5.
    [048] The flux assembly comprises internal and external flux concentrators 28, 29, preferably made of a magnetically malleable material such as a soft iron. The outer flow concentrator 29 is formed of a circular base panel 31 having a peripheral side panel 32. The inner flow concentrator 28 is formed in a disk and although not illustrated, it should be understood that the inner flow concentrator 28 can also be formed with a peripheral side panel. The inner flow concentrator is located within the outer flow concentrator 29 and a concentric annular opening 34 is formed between a peripheral edge 35 of the inner flow concentrator and the peripheral side panel 32 of the outer flow concentrator 29. A space is also formed between a flat surface 36 of the inner flow concentrator 28 and the circular base panel 31 of the outer flow concentrator 29. Both the circular panel 31 of the outer flow concentrator 29 and the inner flow concentrator 28 are formed with a central hole (not shown) through which the axle 14 extends.
    [049] The flux assembly 25 further comprises a permanent magnet 37 located in the space formed between the flat surface 36 of the inner flux concentrator 28 and the circular base panel 31 of the outer flux concentrators 29. The magnet 37 is preferably made of neodymium, iron and boron and is also disk-shaped formed with a central hole (not shown) such that the shaft 14 can extend therethrough. Magnet 37 has a diameter similar to inner flux concentrator 28 such that annular opening 34 also extends between magnet 37 and peripheral side panel 32 of outer flux concentrators 29.
    [050] Referring now to Figure 5, the polarity of magnet 37 is permanent and the north and south poles are represented by ‘N’ and ‘S’. The magnetic field 38 emitted by the magnet 37 is illustrated by lines 30. The magnetic field 38 is substantially radially oriented with respect to the longitudinal axis 'A' of the axis 14 around which the magnet 37 is located, and where the magnet is located. 37 is sandwiched between the inner and outer flux concentrators 28, 29, most of the magnetic field 38 emitted by magnet 37 is contained within the annular opening 34 such that a large magnetic force is generated.
    [051] In addition to the flux assembly 25, the oscillation generator 26 further comprises a solenoid 39 which is affixed to the rear support 13 and is located in the annular opening 34. The solenoid 39 comprises numerous turns of insulated lead wire 40 and is arranged to such that it is concentric with magnet 37 and flux concentrators 28, 29, however, do not contact between solenoid 39 and flux assembly 25. Preferably, solenoid 39 is made of copper wire having 0.15mm in length. diameter, having a resistance of 10.2 R and wound 220 turns.
    [052] Solenoid 39 is electrically connected to battery 7 via an inverter (not shown). The inverter converts the direct current (dc) supplied by battery 7 into alternating current (ac). The alternating current flowing through the coiled wire 39 produces a magnetic field having an alternating polarity that interacts with the permanent magnetic field of the magnet 37 interspersed between the inner and outer flux concentrators 28, 29. As a result of the alternating polarity of the solenoid 39 , magnet 37 and solenoid 39 alternate between being attracted and repelled by each other.
    [053] As described above, the internal and external flux concentrators 28, 29 and the magnet 37 are mounted on the bushing 27 in such a way that the shaft 17 can freely rotate with respect to them. This arrangement also allows bushing 27 and flow assembly 25 to move in an axial direction 'A'. As solenoid 39 is affixed to rear bracket 13 and its polarity is alternated, bushing 27 and flow assembly 25 are moving toward and away from solenoid 39 along axis 14. This generates a movement of vibration or oscillation which is transferred to the front support 12 by means of the e-clip 23 and the rear support 13 by means of stops 41 as will now be explained.
    [054] When an electrical current passes through solenoid 39 in a direction that results in a magnetic field being emitted that repels flux assembly 25, flux assembly 25 rapidly moves along axis 14 toward the support front 12. Forward movement of the flow assembly is stopped when it affects the e-clip 23. This generates an axial force that is transmitted to the shaft 14 through the front support 12 which flexes forward, thereby making the shaft 14 move to a forward position. When the direction of current in solenoid 39 is reversed such that the emitted magnetic field changes polarity and thereby attracts the flux assembly, the flux assembly 25 quickly moves towards the solenoid 39 affixed to the rear support 13 and prevents the stops 41 formed on the rear support 13. As a result of this in combination with that, the user pushes the brush against the skin, the shaft 14 moves to a rearward position. As the direction of current is alternated, the flux assembly oscillates or vibrates along shaft 14 and affects e-clip 23 of front bracket 12 and stops 41 on rear bracket 13 result in shaft 14 oscillating or vibrating on an axial direction of its longitudinal axis 'A'.
    [055] To reduce noise resulting from flux assembly 25 affecting eclip 23 and stops 41, a spring (not shown), such as a curved spring disk, may be located at one or both ends. of the external flux concentrator 29 which affects the eclip 23 and the stops 41. The springs reduce the moment of the flux assembly 25, however, sufficient force is transferred to the eclip 23 and the stops 41 such that axis 14 moves between its forward and backward positions. The springs are preferably made of a non-metallic, age-hardening, high strength beryllium copper alloy. The nominal spring has a spring rate of 3.2N/mm and so the spring rate at the frequency of 80Hz is 2.8N/mm and the spring rate at the frequency of 110Hz is 5.3N/mm.
    [056] The device 1 further comprises a frequency converter (not shown) that changes the frequency of the alternating current so that the resulting oscillation of the flux set 25 can be changed. In a preferred embodiment, the frequency converter is configured to convert frequency between two modes; the first mode being at 80Hz and the second mode being at 110Hz. A higher frequency produces less audible noise than a lower frequency mode because changing the direction of the flux set is faster, which prevents the flux set from affecting the e-clip 23 and stops 41 with such a larger compared moment at a lower frequency.
    [057] The fact that the components of the oscillation generator 26 are not mechanically connected to the shaft 14, results in the oscillation movement which is independently controlled with respect to the rotational movement. Therefore, device 1 can be configured to operate in various modes. For example, the operating switch can have eight settings that correspond to eight operating modes that are based on three rotational speeds; 0, 180 and 250 rpm, and three oscillation frequencies; 0, 80 and 110 Hz. Mode combinations are listed in the table below.

    [058] The device further comprises a controller (not shown) that is configured to control different modes of operation in response to user input. For example, when a user changes the switch in a first configuration so that the device is in its first operating mode, the controller drives battery 7 so that it supplies current to motor 8, and drives motor 8 so that shaft 14 and brush 3 rotate at 180 rpm. Simultaneously, the controller drives the battery 7 so that it supplies current to the oscillating generator 26. The controller further drives the inverter so as to convert the direct current into an alternating current. The controller also sets the frequency converter to 80 Hz. As a result, the oscillation generator 26 also oscillates shaft 14 and brush 3 in the axial direction at 80 Hz.
    [059] If a user subsequently changes the operating mode to operating mode 5 by pressing or moving the switch, the controller interrupts the supply of current from battery 7 to engine 8, but continues to drive the oscillation generator 26 of such that shaft 14 and brush 3 only move in the axial direction. If the user later changes the operating mode to operating mode 6, then the controller drives the frequency converter so as to increase the frequency of the alternating current resulting in a stronger oscillation of axis 14.
    [060] It should be understood that the device is not limited to these eight modes of operation. The device may comprise more or less oscillation frequencies and/or rotational speeds, such that it comprises more or less modes of operation. .
    [061] In an alternative embodiment not illustrated, the device comprises two separate switches, a first switch to control the rotation of the shaft 14 and brush 3 and a second switch to control the oscillation of the shaft 14 and brush 3. The first switch it can have four settings that correspond to four rotational speeds; 0, 180, 220 and 250 rpm, and the second switch can also have four settings corresponding to four oscillation frequencies; 0, 80, 100 and 110 Hz. In this way, the device is configured to have a total of 15 operating modes. Advantageously, the user can actuate the two switches independently of each other so that they can obtain the desired combination of rotation and oscillation movement of the brush 3. It should be understood that the two separate switches are not limited to having four settings each, for example, each switch can be configured to have three settings each, such that the device has a total of eight operating modes.
    [062] When device 1 is operated in an oscillation mode, axis 14 and also brush 3 oscillate or move in a direction parallel to the longitudinal axis 'A' of axis 14. Thus, when the device is in use, the brush 3 and shaft 14 oscillate or move substantially perpendicular to the skin, which improves the cleansing and massaging effect on the skin.
    [063] Advantageously, the configuration of the device as described above allows the oscillating movement and the rotational movement to be independently adjusted to the user's preference.
    [064] It should be understood that the device 1 is not limited to comprising a brush 3, it may comprise an alternative skin treatment part having a rough surface for exfoliation or a surface comprising protrusions for massage.
    [065] In an alternative embodiment not illustrated, the oscillation generator 26 is configured inversely such that the solenoid 39 is mounted on the front support 12 and the axle 14 is formed with a groove in which the rear support 13 is located.
    [066] In yet another embodiment, both the front and rear supports 12, 13 are flexibly connected to the frame 11 and the axle 14 is formed with a second circumferential groove in which the rear frame 13 is located such that the impact the swing generator and the front and rear supports 12, 13 swing or move the axle 14 in an axial direction between the forward and backward positions.
    [067] It should also be understood that the internal and external flux concentrators 28, 29, the permanent magnet 37 and the solenoid 39 are not limited to having a circular cross section with respect to the longitudinal axis of the axis. For example, they can all have a square or rectangular cross section.
    [068] It will be appreciated that the term “comprising” does not exclude other elements or steps and that the indefinite article “a” or “an” does not exclude a plurality.
