[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a HVAC filtering device, comprising: a shell 1, a slot 3 is provided on the inner surface of the shell 1, a filter plate 4 is inserted on the inner surface of the slot 3; a cleaning component 2, the cleaning component 2 is fixedly connected to the outer surface of the shell 1, the cleaning component 2 comprises two support rods 201, a support plate 202 is fixedly connected between the end surfaces of the two support rods 201, an electric push rod 203 is fixedly connected to the outer surface of the support plate 202 close to the shell 1, a push plate 204 is fixedly connected to the end surface of the electric push rod 203, a plurality of springs 205 are evenly fixedly connected to the outer surface of the push plate 204, a connecting plate 206 is fixedly connected between the end surfaces of the plurality of springs 205, and a brush 2 is arranged on the outer surface of the connecting plate 206 07. A top cover 5 is fixedly connected to the top of the outer shell 1. A slot is opened on the top of the top cover 5. An air outlet 6 is fixedly connected to the top of the top cover 5 near the slot. The air outlet 6 is connected to the outer shell 1, and the position of the air outlet 6 matches that of the filter plate 4. A connecting seat 208 is fixedly connected to the outer surface of the push plate 204. A motor 209 is fixedly connected to the outer surface of the connecting seat 208. The output end of the motor 209 slides through the connecting seat 208 and extends to the inside. A rotating shaft 210 is fixedly connected to the output end of the motor 209. The end face of the rotating shaft 210 is rotatably connected to the inner surface of the connecting seat 208. An eccentric wheel 211 is symmetrically fixedly connected to the outer surface of the rotating shaft 210. The outer surface of the eccentric wheel 211 fits the outer surface of the connecting plate 206.

[0024] The effect achieved by the entire embodiment 1 is that when the HVAC filter device is in use, the air blown out by the HVAC is intercepted and filtered by the use of the filter plate 4, and the air filtered by the filter plate 4 is discharged into the room from the air outlet 6. When the filter device needs to be cleaned after being used for a period of time, the electric push rod 203 is started to extend to drive the push plate 204 to move toward the filter plate 4. The push plate 204 can drive the connecting plate 206 to follow the movement through the connection of the spring 205. After the connecting plate 206 moves toward the filter plate 4, it can drive the bristles 207 to insert into the filter plate 4, then start the motor 209, the motor 209 can drive the shaft 210 to rotate, and the rotation of the shaft 210 drives the eccentric wheel 211 to follow the rotation. When the eccentric wheel 211 rotates, it can repeatedly collide with the connecting plate 206. Under the high-speed rotation of the eccentric wheel 211, the connecting plate 206 can generate high-frequency vibration. At this time, the bristles 207 are in a state of being inserted into the pores of the filter plate 4 and generate high-frequency vibration. Therefore, the vibration generated by the bristles 207 can make the dust attached to the filter plate 4 be vibrated out, completing the cleaning process of the filter plate 4.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, a first sealing ring 212 is disposed on the outer surface of the push plate 204 , and a second sealing ring 213 is disposed on the outer surface of the connecting plate 206 . The outer surfaces of the first sealing ring 212 and the second sealing ring 213 are both in contact with the inner surface of the housing 1 .

[0026] The effect achieved by the entire embodiment 2 is that, through the coordinated use of the first sealing ring 212 and the second sealing ring 213, when the electric push rod 203 pushes the push plate 204 to move for cleaning, the push plate 204 and the connecting plate 206 can always be in a fit with the inner wall of the outer shell 1, thereby avoiding air leakage in the gap between the push plate 204 and the connecting plate 206 when they move, which affects the air outlet stability of the HVAC.

[0027] Working principle: when the HVAC filter device is in use, the air blown out by the HVAC is intercepted and filtered through the use of the filter plate 4, and the air filtered by the filter plate 4 is discharged into the room from the air outlet 6. When the filter device needs to be cleaned after being used for a period of time, the electric push rod 203 is started to extend to drive the push plate 204 to move toward the filter plate 4. The push plate 204 can drive the connecting plate 206 to follow the movement through the connection of the spring 205. After the connecting plate 206 moves toward the filter plate 4, it can drive the bristles 207 to insert into the pores of the filter plate 4. Then the motor 209 is started. The motor 209 can drive the rotating shaft 210 to rotate, and the rotation of the rotating shaft 210 drives the eccentric wheel 211 to follow the rotation. When the eccentric wheel 211 rotates, it can repeatedly collide with the connecting plate 206. Under the high-speed rotation of 211, the connecting plate 206 can generate high-frequency vibration. At this time, the bristles 207 are in a state of being inserted into the pores of the filter plate 4 and generate high-frequency vibration. Therefore, the vibration generated by the bristles 207 can make the dust attached to the filter plate 4 be vibrated out, completing the cleaning process of the filter plate 4. After the vibration cleaning is completed, the outer shell 1 is taken out to pour out the dust to complete the cleaning operation of the filter device. The cleaning effect on the filter plate 4 is more thorough. Through the coordinated use of the first sealing ring 212 and the second sealing ring 213, when the electric push rod 203 pushes the push plate 204 to move for cleaning, the push plate 204 and the connecting plate 206 can always be in a fit state with the inner wall of the outer shell 1, avoiding air leakage in the gap between the push plate 204 and the connecting plate 206 when they move, affecting the air outlet stability of the HVAC.

[0028] The wiring diagram of the electric push rod 203 and the motor 209 in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the electric push rod 203 and the motor 209 are not explained in detail.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
