Description

Technical Field

[0001] This utility model relates to the field of fan filtration technology, specifically to a circulating fan filtration device. Background Technology

[0002] Circulating fans are widely used in large workshops, warehouses, and farms due to their wide coverage and low energy consumption. To protect the fan blades and motor from dust, lint, and other impurities, a dust filter is usually installed on the air inlet side. Over time, a large amount of dust easily accumulates on the outside of the dust filter. Some of this dust adheres to the filter surface due to electrostatic adsorption and moisture adhesion. As the dust layer thickens, the air inlet resistance increases significantly, and the fan's air delivery efficiency decreases.

[0003] Common cleaning methods include manual disassembly of dust filters or in-situ brushing of the filters. However, this is time-consuming and labor-intensive when there are many fans. Some existing fans use rotating brushes mounted on the fan blades that scrape the filter surface during airflow. However, the brush itself and its supporting structure continuously obstruct part of the filter's effective airflow area during cleaning, creating permanent air resistance and reducing overall airflow efficiency, thus presenting a practical defect. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a circulating fan filtration device to solve the issue of inconvenient cleaning of dust accumulated on the surface of the circulating fan dust filter.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a circulating fan filtration device, including a fan housing, an air supply mechanism, and a wind speed sensor, and further including a connecting groove, a translation component, a flipping component, a cleaning brush, and an adsorption component. The air supply mechanism is provided inside the fan housing, and a wind speed sensor is provided at the rear air outlet of the fan housing. A connecting groove is provided on the front air inlet surface of the fan housing. The translation component is slidably installed inside the connecting groove, and the flipping component is rotatably installed inside the connecting groove. There are two sets of flipping components, and the two sets of flipping components are respectively engaged with the upper and lower sides of the translation component. A cleaning brush is fixedly installed on the surface of the flipping component, and the cleaning brush is correspondingly arranged with the front air inlet of the fan housing. An adsorption component is provided on the front side of the rotating end of the air supply mechanism, and the adsorption component is correspondingly arranged with the translation component.

[0006] The fan casing includes a fan duct, a dustproof net, and a protective railing. A dustproof net is fixedly installed at the air inlet on the front side of the fan duct, and a support plate is rotatably installed inside the dustproof net. A protective railing is fixedly installed at the air outlet on the rear side of the fan duct.

[0007] The air supply mechanism includes a motor and fan blades. The motor is fixedly installed inside the air duct, and the fan blades are fixedly installed at the output end of the motor.

[0008] The connecting groove includes a through groove and a recess. The through groove is formed on the surface of the support plate of the dustproof net and extends through the center of the support plate in the front-back direction. The recess is formed on the front side of the support plate of the dustproof net and is connected to the through groove.

[0009] The translation component includes a slide rod, locking teeth, a connecting block, and a limiting plate. The slide rod is slidably installed inside the connecting groove. Locking teeth are fixedly connected to both the upper and lower sides of the slide rod. A connecting block is fixedly installed at the rear end of the slide rod, and a limiting plate is fixedly installed at the rear end of the slide rod.

[0010] The flipping component includes a rotating shaft, a gear, and a torsion spring. The rotating shaft is rotatably installed inside the connecting groove, the gear is fixedly installed on the surface of the rotating shaft, a cleaning brush is fixedly installed at one end of the rotating shaft, and the torsion spring is sleeved on one end of the rotating shaft.

[0011] The adsorption component consists of a socket and an electromagnet. The socket is fixedly installed at the front axis of the fan blade, and the electromagnet is embedded in the front of the socket.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention uses an adsorption component to attract the connecting block, and a traction slide rod slides inside the through groove until the limiting plate is inserted into the adsorption component. As the slide rod moves, the meshing of the locking teeth and gears drives the rotating shaft to rotate inside the through groove and recess. The rotating shaft causes the cleaning brush connected to it to rotate, changing the cleaning brush from a horizontal position perpendicular to the dustproof net to a vertical position against the front of the dustproof net. The drive motor drives the fan blades to rotate slowly. Through the connection between the adsorption component and the limiting plate, the support plate rotates at the dustproof net, thereby causing the cleaning brush to clean the area intercepted by the front of the dustproof net. The accumulated layers of dust are scraped and cleaned. After rotating for a period of time, the cleaning work stops, the adsorption of the adsorption component to the connecting block is released, and the cleaning brush is rotated and reset by the torsion spring. Through the conduction of the flipping component and the translation component, the limiting plate is separated from the adsorption component, and the connection between the two is broken. The cleaning brush changes from a vertical state to a horizontal state, thereby avoiding the cleaning brush from continuously blocking the front of the dustproof net during daily work, causing wind resistance and affecting the air supply efficiency. Moreover, the blowing airflow will pass over the surface of the cleaning brush, blowing off the small amount of dust that is scraped off the cleaning brush after the cleaning work.

The flipping component 6 is rotatably installed inside the connecting groove 4. There are two sets of flipping components 6, and the two sets of flipping components 6 are respectively engaged with the upper and lower sides of the translation component 5. The cleaning brush 7 is fixedly installed on the surface of the flipping component 6. The cleaning brush 7 is correspondingly arranged with the front air inlet of the fan housing 1. The adsorption component 8 is located on the front side of the rotating end of the air supply mechanism 2, and the adsorption component 8 is correspondingly arranged with the translation component 5.

[0025] The fan housing 1 includes a fan duct 101, a dustproof net 102 and a protective railing 103. The dustproof net 102 is fixedly installed at the air inlet on the front side of the fan duct 101. A support plate is rotatably installed inside the dustproof net 102. The protective railing 103 is fixedly installed at the air outlet on the rear side of the fan duct 101.

[0026] Specifically, the air supply mechanism 2 inside the air duct 101 is protected, the air inlet of the air duct 101 is protected from dust by the dustproof net 102, the air outlet of the air duct 101 is safely isolated by the protective railing 103, the air supply mechanism 2 blows air, the wind speed sensor 3 detects the gas flow rate at the fan housing 1, the adsorption component 8 adsorbs and pulls the translation component 5, causing the translation component 5 to slide inside the connecting groove 4, the translation component 5 causes the flipping component 6 to rotate inside the connecting groove 4, and the flipping component 6 causes the cleaning brush 7 to flip, controlling its switching between horizontal and vertical states.

[0027] The air supply mechanism 2 includes a motor 201 and a fan blade 202. The motor 201 is fixedly installed inside the air duct 101, and the fan blade 202 is fixedly installed at the output end of the motor 201.

[0028] Specifically, the motor 201 drives the fan blades 202 to rotate, thereby achieving the required air delivery function.

[0029] The connecting groove 4 includes a through groove 401 and a recess 402. The through groove 401 is opened on the surface of the support plate of the dustproof net 102 and passes through the center of the support plate in the front-back direction. The recess 402 is opened on the front side of the support plate of the dustproof net 102 and is connected to the through groove 401.

[0030] Specifically, the slide bar 501 is supported by the through groove 401 and slides stably inside it, while the rotation range of the cleaning brush 7 is limited by the groove 402.

[0031] The translation component 5 includes a slide rod 501, a locking tooth 502, a connecting block 503, and a limiting plate 504. The slide rod 501 is slidably installed inside the through groove 401. The locking tooth 502 is fixedly connected to both the upper and lower sides of the slide rod 501. The locking tooth 502 is meshed with the gear 602. The connecting block 503 is fixedly installed at the rear end of the slide rod 501. The connecting block 503 is correspondingly arranged with the adsorption component 8. The limiting plate 504 is fixedly installed at the rear end of the slide rod 501. The limiting plate 504 is inserted into the adsorption component 8.

[0032] Specifically, the sliding rod 501 slides inside the through groove 401, causing the locking tooth 502 to drive the gear 602 that meshes with it to rotate. The connecting block 503 is attracted and pulled by the adsorption member 8, causing the sliding rod 501 to slide closer to the adsorption member 8. The limiting plate 504 is inserted and fixed to the adsorption member 8, so that rotating the adsorption member 8 drives the translation member 5 and the connected components to rotate.

[0033] The flipping component 6 includes a rotating shaft 601, a gear 602, and a torsion spring 603. The rotating shaft 601 is rotatably mounted inside the through groove 401 and extends through the connection between the through groove 401 and the recess 402 into the interior of the recess 402. The gear 602 is fixedly mounted on the surface of the rotating shaft 601. The gear 602 is located inside the through groove 401 and is meshed with the retaining tooth 502. A cleaning brush 7 is fixedly mounted on one end of the rotating shaft 601.

The other end of the torsion spring 603 is connected to the inner wall of the recess 402.

[0034] Specifically, the gear 602 is driven by the snap ring 502, which in turn drives the rotating shaft 601 to rotate. The rotating shaft 601 drives the cleaning brush 7 to flip, controlling the cleaning brush 7 to be in contact with or away from the front side of the dustproof net 102. The torsion spring 603 applies force to the rotating cleaning brush 7, pushing it to rotate from the vertical state back to the horizontal state.

[0035] The adsorption component 8 consists of a socket and an electromagnet. The socket is fixedly installed at the front axis of the fan blade 202, and the electromagnet is embedded in the front of the socket. The socket and the limiting plate 504 are correspondingly set, and the electromagnet and the connecting block 503 are correspondingly set.

[0036] Specifically, the connecting block 503 is attracted and pulled by an electromagnet, and then connected to the limiting plate 504 through a socket to complete the connection and fixation of the adsorption component 8 and the translation component 5.

[0037] In summary: When this utility model is in use, workers use the device in large workshops, warehouses, farms and other places. The motor 201 drives the fan blades 202 to rotate, which drives the air flow to achieve the effect of ventilation and air exchange and accelerate the airflow. As the usage time increases, the dustproof net 102 at the air inlet of the air duct 101 blocks dust, lint and other impurities from entering the air duct 101. Some dust stays on the front side of the dustproof net 102 and falls off on its own. Some dust adheres to the surface of the dustproof net 102 due to electrostatic adsorption, moisture adhesion and other reasons. The thickening of the dust layer affects the air flow and reduces the air supply efficiency of the device. The wind speed sensor 3 detects that the air flow rate of the device has decreased at this point.

[0038] To clean the dust filter 102, first stop the motor 201 from rotating the fan blades 202. After the fan blades 202 come to a stop, energize the electromagnet of the adsorption component 8, causing it to attract and pull the connecting block 503. This causes the slide rod 501 to slide inside the through groove 401 towards the adsorption component 8 until the limiting plate 504 is inserted into the socket of the adsorption component 8. During the sliding of the slide rod 501, the teeth 502 on the surface of the slide rod 501 engage with the gear 602, causing the gear 602 to rotate. The gear 602 drives the rotating shaft 601 to rotate inside the through groove 401 and the recess 402, causing the rotating shaft 601 to rotate the cleaning brush 7 at one end, compressing the torsion spring 603 and changing the cleaning brush 7 from a horizontal to a vertical position. The front side of the dustproof net 102 is attached to the drive motor 201, which drives the fan blade 202 to rotate. Relying on the connection between the translation component 5 and the adsorption component 8, the component connected to the translation component 5 rotates accordingly. The cleaning brush 7 is controlled to scrape and clean the dust and impurities accumulated on the front side of the dustproof net 102. After cleaning, the electromagnet at the adsorption component 8 is de-energized, and the translation component 5 is no longer pulled by the adsorption component 8. The spring force of the torsion spring 603 pushes the cleaning brush 7 to flip and reset, which drives the rotating shaft 601 connected to it to rotate and reset. The slide rod 501 slides and resets, so that the limiting plate 504 separates from the adsorption component 8. The horizontal cleaning brush 7 will not hinder the normal operation of the device, and the airflow on the front side of the dustproof net 102 will blow off the small amount of impurities attached to the surface of the cleaning brush 7 due to the cleaning work.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
