    专利说明:

    The invention relates to small-sized appliances for personal use, in particular to razors for dry shaving.
    Known compact vibration household device. The drive of this device contains a stator with iron cores and windings mounted on it. A rotor is mounted rotationally between the stator poles, which contains a permanent magnet and iron poles that interact with the stator poles. The second shoulder of the two-arm rotor lever acts on the knife, moving reciprocating.
    The disadvantages of the design are its complexity and highly elongated shape.
    The purpose of the invention is to simplify the design.
    Figures 1 and 2 show various embodiments of the device, a longitudinal section; FIG. 3 is an electrical circuit for direct frequency doubling.
    In this particular case, a small-sized household appliance is presented in the form of an electric razor. In the housing 1 of the blmtva there is a mounting plate 2 on which a single-phase electric motor 3 of synchronous type is mounted. The electric motor consists of a steel U-shaped core 4 with end arms 5, on which successively connected excitation windings 6 are mounted.
    The rod-shaped permanent magnet 7, magnetized in the longitudinal axial direction of its movement (along arrow 8), is mounted with the possibility of longitudinal movement in the guide means 9

    stator and has pole ends 10, perpendicular to its longitudinal axis.
    The stator has poles 11, which consist of beveled sections, resulting in narrow sections 12 with parallel end faces 13 facing the pole ends 10 of permanent magnet 7. Magnetic non-friction elements 14 serve as a mechanical means of the stator poles. and wedge elements 15, placed on the sloped portions of the stator. In the preferred embodiment, the permanent magnet 7 is placed in a plastic capsule 16,
    A permanent magnet 7 is held in a neutral position with the stator turned off under the action of the compression springs 17 fixed to the ends on the stops 18 and the end walls of the capsule 16.
    As a result of the longitudinal-axial magnetization, the permanent magnet 7 tends to move under the action of a magnetic attraction towards the poles of the stator. In this case, the springs 17 must be sufficiently powerful to keep the permanent magnet in a neutral rest position.
    The permanent magnet capsule 16 has a lever 19, the free end of which has an actuating part 20 interacting with the transition elements 21 of the knife 22 of the shaver. The knife 22 is moved under the fixed hair receiving plate-grid 23 and mounted by means of supporting parts 24 with the possibility of reciprocating movement in the directions along arrow 25.
    In the simplified version of the device shown in Fig. 2, the poles of the U-shaped stator core 4 are located in one plane with a certain step in the direction of movement of the permanent magnet 7 and are closed by the housing partition 26, while the permanent magnet 7 is fixed on the back of the knife 22 By function, the springs 27 are similar to the springs 17. The springs 27 are located under the shaving head, exerting a working impact on the knife 22.
    The principle of operation of both versions of the device is similar. In both cases, the stator poles interact with the face portions of the permanent magnet, and in the embodiment of FIG. 1 this effect is realized in the longitudinal direction, and in the embodiment of FIG. 2, from the side of the partition 26.
    The frequency of the vibrations of the knife is determined by the operating frequency of the electric motor. The electronic control of the device operation can be carried out according to the scheme of full-wave rectification according to the scheme of FIG. 3. According to the circuit, a network alternating voltage of 50 or 60 Hz is applied to the terminals 28,
    which is rectified by a rectifier 29, as a result of which a constant polarity 30 is formed with a double frequency of 100 or 120 Hz, which is applied to the stator windings 6, thus doubling the frequency of the vibration of the knife 22.
    The use of a longitudinally moving permanent magnet makes it possible to reduce the dimensions of the device and simplify its design.
