[0020] The following will provide a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0021] Reference Figure 1-3A purification device with a self-cleaning function comprises a box body 1, a filter plate 2 is arranged at the center of the box body 1, and the inside of the box body 1 is divided into a filter chamber 3 and an adsorption chamber 4 by the filter plate 2, threaded rods 5 are rotatably arranged at both ends of the top wall of the filter chamber 3 close to the filter plate 2, a motor 6 for driving one of the threaded rods 5 to rotate is fixedly installed on the top of the box body 1, a scraper 7 is sleeved on the two threaded rods 5, ventilation holes are opened on both sides of the side wall of the box body 1 away from the filter plate 2, a mechanical fan 8 is rotatably connected to the ventilation hole where the filter chamber 3 is located, and the top of the box body 1 is provided with a fan 8. A transmission assembly is provided for rotating a transmission threaded rod 5 and a mechanical fan 8. The threaded rod 5 is driven to rotate by a motor 6, thereby driving a scraper 7 to scrape and clean the filter plate 2. The mechanical fan 8 is driven to rotate by the transmission assembly to provide auxiliary air intake for the box body 1. Compared with the existing device, the problem of manually removing and cleaning the filter plate 2 inside the equipment is avoided, thereby improving the use efficiency of the purifier. An electric fan 9 is rotatably installed on the vent hole where the adsorption chamber 4 is located, and an activated carbon adsorption layer 10 and a HEPA filter layer 11 are provided between the electric fan 9 and the filter plate 2.

[0022] Reference Figure 2-4 The transmission assembly includes a rotating shaft 12 which is rotatably connected to the top wall and the side wall of the box body 1 respectively. The two rotating shafts 12 are fixedly connected with mutually meshing bevel gears 13. A synchronous component 14 for synchronous rotation is provided between the rotating shaft 12 on the top wall of the box body 1 and the top of the threaded rod 5, and between the rotating shaft 12 on the side wall of the box body 1 and the mechanical fan 8. The synchronous component 14 is a prior art, including a sprocket and a chain. The sprocket and the chain cooperate with the rotating shaft 12 and the bevel gear 13 to realize the transmission of the mechanical fan 8.

[0023] Reference Figure 1-3 A collecting box 15 is slidably provided at the lower end of the scraper 7, and the collecting box 15 is inclined on the side close to the filter plate 2. The top of the collecting box 15 close to the filter plate 2 is beveled, and the edge of the collecting box 15 is fitted with the lower end of the filter plate 2. The inclined setting and bevel treatment can prevent impurity particles from falling to the edge of the collecting box 15 and failing to fall into the collecting box 15, thereby improving the stability of the device.

[0024] A limiting block 16 for limiting the position of the scraper 7 is fixedly connected to the bottom end of the threaded rod 5 . The limiting block 16 is used to limit the position of the scraper 7 , thereby preventing the scraper 7 from moving downward and separating from the threaded rod 5 .

[0025] The activated carbon adsorption layer 10 is composed of activated carbon particles, and the activated carbon adsorbs harmful gases, organic compounds and odors in the air, such as harmful volatile organic compounds such as formaldehyde and benzene.

[0026] The HEPA filter layer 11 is made of polypropylene to filter out tiny particles, such as PM2.5, pollen, viruses, bacteria, etc. The HEPA filter layer 11 can usually achieve a filtration efficiency of more than 99.97%.

[0027] Working principle:

[0028] When the purification device with self-cleaning function is used, the motor 6 and the electric fan 9 are turned on. The electric fan 9 drives the air in the box 1 to pass through the filter plate 2 and intercept larger particles, such as hair, dust, dandruff, etc., to protect the subsequent filter layer from being blocked by large particles. The air then passes through the activated carbon adsorption layer 10, and the activated carbon adsorbs harmful gases, organic compounds and odors in the air, such as formaldehyde, benzene and other harmful volatile organic compounds VOCs. The air then passes through the HEPA filter layer 11 to filter out tiny particles, such as PM2.5, pollen, viruses, bacteria, etc. The HEPA filter layer 11 can usually achieve a filtration efficiency of more than 99.97%, that is, the air is purified. The motor 6 drives the threaded rod 5 to rotate, and then drives the scraper 7 to scrape and clean the filter plate 2. The cleaned debris falls into the collection box 15. The rotating shaft 12 cooperates with the bevel gear 13 and the synchronous component 14 to drive the mechanical fan 8 to rotate, so as to achieve auxiliary air intake in the box 1. The above is the entire use process of the purification device with self-cleaning function.

[0029] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
