The present invention relates to an air purifier of a respirator, and more particularly to a structure and method information recognition on a filter unit installed in an air purifier of a respirator that filters polluted external air and supplies purified air to an employee who works in an extreme environment, wherein the The air purifier is wirelessly connected to the filter unit to provide the employee with information such as type, duration of operation and date of replacement of the filter unit. In general, respirators applied to safety helmets, used during welding, applied to protective masks, and used against asbestos are products used in various industrial fields in extreme environments such as welding, construction and civil engineering to prevent safety-related accidents that may occur while employees work. These respirators applied to safety helmets, used during welding, applied to protective masks, and used against asbestos, which are placed on the heads of employees who work in extreme environments, include air purifiers. air that purifies polluted external air and provides purified air to their users in workplaces where harmful particles, fumes and noxious odors occur and places where infectious diseases occur. These respirators are applied to safety helmets, used during welding, applied to protective masks, and used against asbestos. Here, respirators applied to safety helmets are used in workplaces for welding, grinding and sanding. Respirators used during welding are applied to workplaces for welding and grinding. Respirators applied to protective masks are used during grinding, sanding, coating and dusting of crops and used in pharmaceutical laboratories, places where general particles are generated, and places where infectious diseases occur. . Also, asbestos respirators are used in places where asbestos particles, harmful dust particles, other contaminants and infectious pathogens occur. These respirators purify polluted air such as harmful dust particles, noxious odors and foul smells, which occur in workplaces and provide purified air to employees and users.
[0002] Here, these air purifiers are connected to respirators via air supply tubes, filter out polluted external air, and provide purified air to respirators placed on employees' heads, allowing so employees can easily work in confined spaces and high temperature spaces. On the other hand, Figures 1 and 2 illustrate an air purifier 50 connected to a breathing mask 20 via an air supply tube 30. The air purifier 50 includes a body 51 in the air purifier 50. which is an installation space 51a, a filter unit 53 removably installed in the installation space 51a of the body 51 for filtering and purifying the polluted air supplied from the outside, and a fan (not shown ) to supply the purified air filtered by the filter unit 53 to the breathing mask 20 via the air supply tube 30. Here, the filter unit 53 includes a particulate removal filter or a odor removal filter. The particulate removal filter is a high performance filter having an average purification rate capable alone of filtering particles having a size of about 0.3 p, in which it is possible to allow air to pass through. and filter 99.9% off various pollutants, agricultural pesticides, fine dust and infectious pathogens. The odor removal filter has an excellent deodorizing force to filter out harmful elements such as foul odors and odors passing through the particulate removal filter. Here, the filter unit 53 further includes a prefilter (not shown) and a wire mesh (not shown). When the filter unit 53 is installed in the installation space 51a of the body 51, a filter cover 54 which secures the filter unit 53 and includes an inlet 54a to allow external air to it is expected to flow there.
[0003] For this reason, the filter unit 53 including one of the odor removal filter and the particle removal filter is inserted and installed in the installation space 51a formed in the body 51 of the air purifier. 50, the prefilter is provided outside the filter unit 53, the wire mesh is provided outside the prefilter, and the filter cover 54 is provided on the outside of the wire mesh while being Removably installed and fixed in front of the body 51.
[0004] With the structure described above, the polluted external air flows into the air purifier 50 via the inlet 54a of the filter cover 54 fixedly installed in front of the body 51. Contaminated external air flowing through the filter cover 54 is supplied to the prefilter via the wire mesh to be filtered. The pre-filter filtered air is supplied to the filter unit 53 formed from one of the particulate removal filter and the odor removal filter to be filtered and purified. The purified air, according to the blower drive, is supplied to the breathing mask 20 via the air supply tube 30. Likewise, an air supply amount is regulated for each level according to the need of a user. Here, a control unit (not shown) which controls a state of the filter unit 53 and various sensors is provided in the air purifier 50. A switching input unit, whose numerical reference is not shown in the drawings, which provides input an operation order such as a temperature, an air flow volume, a quantity of oxygen, turned on / off, etc., and a control panel. the liquid crystal display (LCD) 57, which displays various data values and the state of the filter unit 53 are provided on a high surface 15 of the air purifier 50. On the other hand, the air purifier Air 50 has a structure that is simple and easy to wear around the waist of the user with a belt, shoulder strap, or X-strap. Air purifier 50 is worn around the waist of an employee using the belt and / or similar means during use, when of which the respirator 20 and the air purifier 50 are placed on the employee's body and the air supply tube 30 which connects the respirator 20 to the air purifier 50 is installed for use. A change in the amount of airflow during work such as a blockage caused by a discharged battery and a filter abnormality or a blockage caused by the foreign substances is detected, and if the detected change is present it is displayed on the LCD panel 57 to inform the employee. As described above, since there is a difference between load rates of filter units mounted and installed in air purifiers connected to a respirator through air supply tubes in accordance with their specifications. types, it is necessary for an employee to assemble a filter unit suitable for a workplace and a working condition on an air purifier and simultaneously with entering and setting a type of the air cleaner unit. filter mounted on the air purifier. That is, the worker mounts and installs a different filter unit depending on the workplace or the working conditions, for example, the particulate removal filter or the odor removal filter. in the air purifier then it is necessary for the employee to enter and directly manually adjust the type of the filter unit installed in the air purifier. Here, between the particulate removal filter and the odor removal filter mounted and installed in the air purifier as a filter unit, the odor removal filter has a filtration density. superior to the particulate removal filter. As a result, when the type of filter unit mounted and installed in the air purifier is not entered and adjusted, malfunction and error may occur. That is, when the particulate removal filter is mounted in the air purifier installation space and the employee enters and sets a type as a disposal filter. odor through the LCD panel of the air purifier, since the particulate removal filter having a lower filtration density than the odor removal filter is recognized as the odor removal filter, a rate load is detected as low and the occurrence of an abnormality and an error in the filter unit recognized as not performing purification and filtration of polluted external air is detected. When the odor removal filter is mounted in the air purifier installation space and the employee enters and sets a type as a particulate removal filter through the LCD panel of the air purifier. air purifier, since the odor removal filter having the higher filtration density than the particulate removal filter is recognized as a particulate removal filter, a charge rate is detected as being high and a Blocking phenomenon of the filter unit is detected. For this reason, when the employee replaces the filter unit with an anomaly or error text displayed on the LCD panel, inconvenience may occur and the work efficiency is deteriorated, for example, a duration of time. work increases. On the other hand, a reference life of the filter unit mounted and installed in the air purifier is generally determined. When the filter unit exceeds the reference life, the filter unit mounted in the air purifier is replaced by a new filter unit. For this reason, depending on the charge rate of the filter unit mounted and installed in it, the air purifier allows the employee to recognize a date of exchange and replacement of the filter unit by through the LCD panel. However, as described above, when the input and setting by the employee are wrong and an error and malfunction occur in the air purifier because of this, not only does an unnecessary expense occur, for example, the filter unit that does not exceed the reference life is changed and replaced but also the environment is polluted due to the discarded filter unit. Similarly, when it is necessary to change and replace the filter unit due to an abnormality of the filter unit during work, the job is stopped and the filter unit is changed and replaced, and At the same time, the type of the filter unit is entered and then the job is done again, which deteriorates the efficiency and continuity of the work. Similarly, when operation of the filter unit is stopped during work to allow the employee to recognize the date of exchange and replacement of the filter unit, the polluted external air does not. is not purified by the air purifier and supplied to the respirator via the air supply tube 30 so that the user who breathes the polluted air has difficulty breathing or the user finds himself exposed without defense to harmful gases. In addition, when welding fumes are included in the unpurified air, the welding fumes and perspiration of the user may adhere together on the periphery of the eyes and respiratory system and may cause safety-related accidents such as visual impairment, skin damage, pneumoconiosis, etc.

[0020] On the other hand, the filter unit 53 is the odor removal filter 53b whose total operating time is 500 hours and is mounted and installed in the installation space 51a of the purifier body 51 50. When the air purifier 50 is turned on and in use, the RFID tag 55b included in the filter unit 53 is read by the RFID reader 55a of the air purifier 50 and the information data of the filter unit 53 read by the RFID reader 55a is transmitted to the control unit.
[0021] The control unit compares and verifies the serial number of the filter unit 53 transmitted and supplied by RFID to a previously stored serial number of the filter unit 53 and recognizes that the filter unit 53 is newly mounted .
[0022] As described above, when the control unit confirms that the filter unit 53 is a new unit that has not been used previously, the counting starts from 0. When the air purifier 50 is turned off to complete the operation of the filter unit 53 after having run for 4 hours, the control unit again stores a serial number of the filter unit 53 mounted in the air purifier 50 and simultaneously stores the filter unit 53 as odor removal filter 53b and stores a total run time, a last run time and a residual run time of the odor removal filter 53b as 500 hours, 4 hours and 496 hours, respectively.
[0023] On the other hand, when the remaining operating time of the filter unit 53 is a certain duration or less, an exchange text is displayed on the LCD panel 57 of the air purifier 50, and an audible warning is product, or an LED is lit and flashing to allow the employee to recognize a replacement and exchange date of the filter unit 53. That is, when the last operating time of the If the filter unit 53 whose total operating time is 500 hours is detected to be 475 hours or more, the control unit displays the total operating time, the last operating time and the remaining operating time of the filter unit 53 via the LCD panel 57 of the air purifier 50 and simultaneously display instructions texts, replacement and exchange of the filter unit 53, produces a warning sound such as an alarm, 20 lights o u repetitively flashes an LED to allow the employee to recognize the replacement and exchange date of the filter unit 53. Here, the replacement and exchange date of the filter unit 53 can be communicated to the employee when the remaining operating time of the filter unit 53 is 5% or less of the total operating time. However, the replacement and exchange date of the filter unit 53 may be recognized by the employee when the remaining operating time of the filter unit 53 is from 1% to 30% or can be set from various ways by arbitrary operation and adjustment of the employee. As described above, according to the embodiments of the present invention, an air purifier and a filter unit are wirelessly connected by RFID, Wi-Fi, CCP, Bluetooth or Zigbee so that a misrecognition of a filter unit and replacement and exchange of an expired filter unit are relayed to prevent safety related accidents in advance.
