[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer toFigures 1 to 4 , in the embodiment of the present utility model, an air purification device with a self-cleaning air outlet includes an outer frame 1. One end of the outer frame 1 is fixedly installed with a filter net 2. Hole grooves 3 are distributed on the end face of the filter net 2. One end of the filter net 2 is installed with a receiving frame 4. The receiving frame 4 is of a hollow structure, and the inner cavity of the filter net 2 is communicated with the inner cavity of the receiving frame 4. A strip-shaped groove 16 is provided at the docking position of the filter net 2 and the receiving frame 4; a cleaning mechanism penetrating below the filter net 2 is installed in the inner cavity of the receiving frame 4, and a driving and guiding mechanism extending into the inner cavity of the filter net 2 is installed outside the filter net 2. The driving and guiding mechanism is used to drive the cleaning mechanism to move reciprocally.

[0022] In this embodiment: When the air purification device purifies air, the air enters the air purification device through the filter net 2. The filter net 2 filters impurities in the air. During long-term use, more impurities adhere to the surface of the filter net 2. At this time, some of the hole grooves 3 are blocked by impurities, and the cross-section of the air inlet channel decreases. At this time, by starting the driving and guiding mechanism to operate, the driving and guiding mechanism drives the cleaning mechanism to move reciprocally, and the cleaning mechanism is started. The reciprocally moving and operating cleaning mechanism effectively cleans the impurities adhering to the surface of the filter net 2.

[0023] Please refer specifically to Figure 2 , Figure 3 and Figure 4 , the driving and guiding mechanism includes a threaded rod 13 and a guide rod 15. The guide rod 15 is fixedly installed between the side end plates of the filter net 2. The threaded rod 13 is rotatably installed between the side end plates of the filter net 2. The threaded rod 13 and the guide rod 15 are symmetrically arranged in the up and down directions; a forward and reverse motor 14 is installed at one outer end of the receiving frame 4, and the output end of the forward and reverse motor 14 is fixedly connected to one end of the threaded rod 13.

[0024] In this embodiment: By starting the forward and reverse motor 14, the forward and reverse motor 14 operates to drive the threaded rod 13 to rotate. At this time, the connecting block 12 threadedly connected to the threaded rod 13 moves. The connecting block 12 drives another connecting block 12 to move along the guide rod 15 through the cleaning mechanism. The two connecting blocks 12 drive the cleaning mechanism to move reciprocally.

[0025] Please refer specifically to Figure 2 , Figure 3 and Figure 4 , the cleaning mechanism includes a suction pipe 10. A plurality of horn-shaped suction nozzles 11 are vertically and equidistantly distributed on the outer periphery of the suction pipe 10. The inner cavities of the plurality of horn-shaped suction nozzles 11 are communicated with the inner cavity of the suction pipe 10. The bottom end of the suction pipe 10 is connected with an L-shaped pipe 7 penetrating below the filter net 2. The other end of the L-shaped pipe 7 is fixedly connected with a corrugated pipe 8. A fixing rod 9 for limiting one end of the corrugated pipe 8 is fixedly connected to the outside of the filter net 2.

[0026] In this embodiment: The air pump connected to the corrugated pipe 8 is started synchronously. At this time, the two connecting blocks 12 drive the suction pipe 10 to move. The moving suction pipe 10 drives the L-shaped pipe 7 to move, and the moving L-shaped pipe 7 squeezes or pulls the corrugated pipe 8.

[0027] The suction force formed by the started air pump passes through the corrugated pipe 8, the L-shaped pipe 7 and the suction pipe 10, and the suction ports are formed on the plurality of trumpet-shaped suction nozzles 11. The suction force acts on the impurities attached to the filter net 2. When the impurities are subjected to the suction force, they are sucked into the trumpet-shaped suction nozzles 11. The impurities enter the corrugated pipe 8 through the suction pipe 10 and the L-shaped pipe 7. This process can effectively clean the filter net 2. It should be noted that: When performing self-cleaning, the use of the cleaning device needs to be stopped to avoid the suction force generated by the cleaning mechanism from being unable to effectively suck in the impurities.

[0028] Please refer specifically to Figure 2 , connecting blocks 12 are integrally formed at symmetric positions on the upper and lower outer peripheries of the suction pipe 10. The connecting block 12 located above is threadedly connected to the threaded rod 13, and the connecting block 12 located below is slidably connected to the guide rod 15.

[0029] In this embodiment: When the threaded rod 13 rotates, the connecting block 12 threadedly connected to the threaded rod 13 moves under the action of its internal thread.

[0030] Please refer specifically to Figure 2 , a notch 6 is opened on the bottom plate of the filter net 2 and the receiving frame 4. The notch 6 is used to provide guidance for the movement of the L-shaped pipe 7.

[0031] In this embodiment: The notch 6 allows the L-shaped pipe 7 to move, preventing the L-shaped pipe 7 from interfering during the movement process.

[0032] Please refer specifically to Figure 1 , a motor cover 5 is installed at one external end of the receiving frame 4. The motor cover 5 is used to protect the forward and reverse motor 14, and a wire hole is opened below the interior of the motor cover 5. The wire of the forward and reverse motor 14 passes through the wire hole and is electrically connected to an external controller.

[0033] In this embodiment: The motor cover 5 can prevent dust and rain from coming into contact with the forward and reverse motor 14, protecting the forward and reverse motor 14.

[0034] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
