The fan drives airflow through the filter, removing particulate matter and uniformly distributing clean air. It can be used as a standalone unit or in combination to adapt to different space requirements.

[0003] Utility model patent CN214170888U discloses an FFU (Fan Filter Unit) fresh air purification device, belonging to the technical field of FFU purification systems. The FFU fresh air purification device includes an FFU body, a ventilation duct at the front of the FFU body, an air inlet at the front end of the ventilation duct, a dust filter at the front of the impeller, and a dust removal component at the front of the dust filter. This utility model features a compact and reasonable structural design, good cleaning effect, and avoids the problem of filter clogging and reduced equipment efficiency that often occurs during long-term use.

[0004] When an FFU device is in operation, it needs to draw in outside air. In order to improve air purification efficiency, impurities in the air are filtered first. Although the filter in the aforementioned patent improves the cleaning effect, the dust filter rotates for a long time, which increases the wear of the dust filter and can easily affect the sealing performance of the dust filter. Therefore, we provide an FFU purification device to solve the above problems. Summary of the Invention

The support frame supports and fixes the filter screen, improving the stability of the filter screen in use.

[0008] Preferably, a power gear is rotatably connected inside the fixed shell, and the power gear meshes with a rotating gear ring. An electric motor is fixedly connected to the top of the fixed shell, and the output end of the electric motor is fixedly connected to the power gear.

[0010] Preferably, a circulating fan is fixedly connected to the top of the circulation box, and the filter is located outside the circulating fan. The output end of the circulating fan is fixedly connected to an air outlet pipe. The air outlet pipe passes through the air inlet pipe and is fixedly connected to the air outlet rod. The bottom end of the air outlet pipe is fixedly connected to the air inlet pipe. Through the circulating fan, the flowing air passes through the circulation box, the filter, and the air outlet pipe into the air outlet rod, and then passes through the dust collection shell and the impurity outlet into the circulation box, so that the air flows inside the air inlet pipe.

[0011] Preferably, the bottom end of the air outlet rod is fixedly connected to the fixed shell, and the top end of the air outlet rod is fixedly connected to the connecting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application supplies fresh outside air to the FFU main unit through the air inlet duct. The rotating gear ring is sealed and fixed by the fixed shell, and the filter screen is fixed by the rotating gear ring. When the rotating gear ring rotates, it drives the filter screen to rotate, which facilitates the dust removal mechanism to clean the dust and impurities on the surface of the filter screen, improving the convenience of filter screen cleaning. The cleaning brush washes the dust on the surface of the filter screen and removes the dust. Air is supplied to the air outlet through the circulation box, blown onto the filter screen through the air outlet, and the dust removed from the filter screen surface is sucked up by the dust suction shell. This prevents dust from entering the interior of the air inlet duct when the cleaning brush cleans the dust on the filter screen surface, improving the stability of the filter screen cleaning operation. Outside air is drawn into the circulation box through the impurity outlet, and the dust and impurities cleaned by the cleaning brush are sucked into the circulation box by the air flow.

[0015] 2. This application uses a support frame to support and fix the filter screen, improving the stability of the filter screen in use. Bolt connections facilitate replacement of the filter screen when it is damaged, improving the convenience of filter screen maintenance. A protective net protects the air inlet duct and prevents large impurities from entering, improving the stability of the air transported by the air inlet duct. An electric motor controls the rotation of the power gear, which in turn controls the rotation of the rotating gear ring inside the air inlet duct, improving the stability of the rotating gear ring's rotation. A dust collection bin stores impurities transported from the impurity outlet, improving the filter screen's cleaning effect. The filter discs further enhance the cleaning of the filter screen. Impurities are isolated to prevent them from flowing outwards when the circulating fan draws in air. The circulating fan directs the airflow through the circulation box, filter, and outlet pipe into the outlet rod, and then through the dust collection housing and impurity outlet into the circulation box. This circulates the air within the inlet duct, improving the cleaning effect of the filter. The outlet rod is fixed by a connecting bracket, which positions and seals the support frame, thereby improving the stability of the filter operation. The dust collection housing is also fixed by the connecting bracket, improving the ease of installation. Bolt fixation allows for easy disassembly of the dust collection housing when the filter needs to be replaced, improving filter maintenance efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As shown in Figures 1-4, this utility model provides a technical solution for an FFU purification device, including an FFU main unit 1. The air inlet of the FFU main unit 1 is fixedly connected to an air inlet pipe 2. The air inlet pipe 2 is internally equipped with a filter mechanism 3 and a dust removal mechanism 4. The filter mechanism 3 includes a fixed housing 301 fixedly connected to the air inlet pipe 2. A rotating gear ring 302 is rotatably connected inside the fixed housing 301. A filter screen 303 is installed on the surface of the rotating gear ring 302. Fresh air from the outside is supplied to the FFU main unit 1 through the air inlet pipe 2. The fixed housing 301 seals and fixes the rotating gear ring 302, and the rotating gear ring 302 fixes the filter screen 303. When the rotating gear ring 302 rotates, it drives the filter screen 303 to rotate, which facilitates the dust removal mechanism 4 to clean the dust and impurities on the surface of the filter screen 303, improving the convenience of cleaning the filter screen 303.

[0023] FFU host 1 is an existing device, and its internal structure will not be described in detail in this application. FFU host 1 is equipped with a fan that can draw in outside air.

[0024] The filter screen 303 and the rotating toothed ring 302 are connected by bolts. The rotating toothed ring 302 is rotatably connected to the air inlet duct 2. The filter screen 303 is internally fixedly connected to a support frame 304. The surface of the air inlet duct 2 is equipped with a protective net 307. The support frame 304 supports and fixes the filter screen 303, improving the stability of the filter screen 303 in use. The bolt connection makes it easy to replace the filter screen 303 when it is damaged, improving the convenience of filter screen 303 maintenance. The protective net 307 protects the air inlet duct 2 and can prevent large impurities from entering the interior of the air inlet duct 2, improving the stability of the air transported by the air inlet duct 2.

[0025] A power gear 305 is rotatably connected inside the fixed housing 301, and the power gear 305 is meshed with the rotating gear ring 302. A motor 306 is fixedly connected to the top of the fixed housing 301, and the output end of the motor 306 is fixedly connected to the power gear 305. The motor 306 controls the rotation of the power gear 305, thereby controlling the rotation of the rotating gear ring 302 inside the air inlet duct 2, which improves the stability of the rotation of the rotating gear ring 302.

[0026] The dust removal mechanism 4 includes a circulation box 401, an air outlet 406, and a dust collection shell 408. A cleaning brush 409 is fixedly connected inside the dust collection shell 408, and the cleaning brush 409 abuts against the filter screen 303. The bottom of the air inlet duct 2 has an impurity outlet 410 connecting the circulation box 401 and the dust collection shell 408. The cleaning brush 409 can be made of materials such as silicone, rubber, and bristles. The cleaning brush 409 washes the dust on the surface of the filter screen 303, cleaning the dust off, and then passing it through the circulation box 401 to the air outlet 406. 6. Air is supplied and blown onto the filter screen 303 through the air outlet 406. The dust cleaned off the surface of the filter screen 303 is then sucked up by the dust suction shell 408. This prevents dust from entering the air inlet duct 2 when the cleaning brush 409 is cleaning the surface of the filter screen 303, thus improving the stability of the filter screen 303 cleaning operation. Outside air is drawn into the circulation box 401 through the impurity outlet 410. The dust and impurities cleaned off by the cleaning brush 409 are then sucked into the circulation box 401 by the air flow.

[0027] The circulation box 401 is fixedly connected to the air inlet duct 2. The dust storage bin 402 is slidably connected inside the circulation box 401, and the impurity outlet 410 is opened directly above the dust storage bin 402. The dust storage bin 402 stores the impurities transported by the impurity outlet 410, thereby improving the cleaning effect of the filter screen 303.

[0028] A filter 403 is fixedly connected inside the circulation box 401. A circulation fan 404 is fixedly connected to the top of the circulation box 401, and the filter 403 is located outside the circulation fan 404. An air outlet pipe 405 is fixedly connected to the output end of the circulation fan 404. The air outlet pipe 405 passes through the air inlet pipe 2 and is fixedly connected to the air outlet rod 406. The bottom end of the air outlet pipe 405 is fixedly connected to the air inlet pipe 2. Impurities are isolated by the filter 403 to prevent them from flowing outward when the circulation fan 404 draws in air. The circulating fan 404 causes the flowing air to pass through the circulation box 401, the filter 403, and the air outlet pipe 405 into the air outlet rod 406, and then through the dust collection shell 408 and the impurity outlet 410 into the circulation box 401. This causes the air to flow inside the air inlet pipe 2, improving the cleaning effect of the filter screen 303.

[0029] The bottom end of the air outlet rod 406 is fixedly connected to the fixed housing 301, and the top end of the air outlet rod 406 is fixedly connected to the connecting frame 407. The connecting frame 407 is fixedly connected to the fixed housing 301, and the support frame 304 is movably connected to the connecting frame 407. The air outlet rod 406 is fixed through the connecting frame 407, and the support frame 304 is positioned and sealed, thereby improving the stability of the filter screen 303 operation.

[0030] The top of the dust collection housing 408 is snapped into the connecting frame 407, and the dust collection housing 408 is assembled and connected to the connecting frame 407 by bolts. The bottom of the dust collection housing 408 is slidably connected to the air inlet duct 2, and the dust collection housing 408 is connected to the impurity outlet 410. The dust collection housing 408 is fixed by the connecting frame 407, which improves the convenience of dust collection housing 408 installation. After being fixed by bolts, the dust collection housing 408 can be easily disassembled when the filter screen 303 needs to be replaced, which improves the maintenance efficiency of the filter screen 303.

[0031] The electric motor 306 and the circulating fan 404 are existing technologies. This application will not go into detail about their specific parameters and models. The electric motor 306 and the circulating fan 404 are electrically connected to the controller inside the FFU host 1. When it is difficult for the FFU host 1 to draw in air, the electric motor 306 and the circulating fan 404 are started to clean the filter screen 303.

[0032] When this invention is in use, if it is difficult for the FFU unit 1 to draw in air, the motor 306 and the circulating fan 404 are started. The circulating fan 404 draws air through the circulation box 401, the filter 403, and the air outlet pipe 405 into the air outlet rod 406, and then through the dust collection shell 408 and the impurity outlet 410 into the circulation box 401. At the same time, the motor 306 controls the power gear 305 to rotate, which causes the rotating gear ring 302 to drive the filter screen 303 to rotate. The cleaning brush 409 washes the dust off the surface of the filter screen 303, and the cleaned dust is drawn into the circulation box 401 by the flowing air. After the filter screen 303 is cleaned, the impurities fall into the dust storage bin 402 under the action of gravity. The dust storage bin 402 stores the impurities, and the staff can clean the impurities in the dust storage bin 402 regularly. This reduces the maintenance difficulty of the FFU unit 1 and improves the stability of the FFU equipment operation.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
