The driving motor 301 drives the transmission belt 302 to rotate reciprocatingly through the output shaft. When the transmission belt 302 rotates, it meshes with the gear 303. The transmission belt 302 drives the gear 303 to rotate reciprocatingly. The rotation of the gear 303 drives the baffle 3 to swing reciprocatingly. The reciprocating swing of the baffle 3 drives the cleaning plate 305 to swing reciprocatingly and rub the surface of the filter plate 4, and the dust accumulated on the surface of the filter plate 4 is taken away, thereby achieving the effect of cleaning the surface of the filter plate 4. There is no need to remove the filter plate 4 for cleaning, which saves a lot of time for cleaning the filter net, reduces the cleaning steps of the filter net, and improves the cleaning efficiency of the filter net.

[0028] Among them, the cleaning plate 305 is arranged at an angle, and the inclination direction of the cleaning plate 305 is toward the filter plate 4. Through the inclination angle, the cleaning plate 305 can contact the surface of the filter plate 4 in advance when the baffle 3 rotates, thereby expanding the cleaning range of the cleaning plate 305 and improving the practicality of the device.

[0029] Among them, the disassembly structure includes an elastic member 403 and a clamping block 404. A plurality of cavities are provided on the inner wall of the external unit 1. A clamping block 404 is movably connected in each cavity. The clamping block 404 is slidably connected to the cavity in the external unit 1.

[0031] Among them, one end of the clamping block 404 is in an arc shape, the filter plate 4 is provided with a clamping groove, the filter plate 4 and the clamping groove of the clamping block 404 are chamfered, and the arc shape at the end of the clamping block 404 and the chamfering inside the clamping block 404 enable the clamping block 404 and the elastic member 403 to be quickly separated and clamped.

[0032] Among them, a magnetic block 402 is fixedly connected to the external unit 1, and the filter plate 4 is magnetically attracted to the magnetic block 402. The filter plate 4 is fixed by the magnetic block 402, and the filter plate 4 is adsorbed by the suction force of the magnetic block 402, thereby preventing the filter plate 4 from being fully inserted therein, resulting in the block 404 not being engaged with the filter plate 4, and fixing the position of the filter plate 4.

[0033] Among them, a collecting groove 5 is clamped at the bottom of the outdoor unit 1, and the collecting groove 5 is located between the filter plate 4 and the baffle 3.

By pulling and pulling, the filter plate 4 can be quickly replaced, thereby improving the replacement effect of the filter plate 4.

[0035] A rooftop air conditioning unit includes an indoor unit 2, the wall of the indoor unit 2 is provided with an air outlet, and the air outlet is provided with all the above-mentioned filtering air intake grille components. The outdoor unit 1 is fixedly installed in the cavity of the indoor unit 2. By arranging the above-mentioned filtering air intake grille components, the entire device can drive the cleaning plate 305 to swing back and forth to rub the surface of the filter plate 4, and take away the dust accumulated on the surface of the filter plate 4, thereby achieving the effect of cleaning the surface of the filter plate 4. There is no need to remove the filter plate 4 for cleaning, which saves a lot of time for cleaning the filter net, reduces the cleaning steps of the filter net, and improves the cleaning efficiency of the filter net.

[0036] Working principle: the driving motor 301 drives the transmission belt 302 to rotate back and forth through the output shaft. When the transmission belt 302 rotates, it meshes with the gear 303. The transmission belt 302 drives the gear 303 to rotate back and forth. The rotation of the gear 303 drives the baffle plate 3 to swing back and forth. The reciprocating swing of the baffle plate 3 drives the cleaning plate 305 to swing back and forth to rub the surface of the filter plate 4, and the dust accumulated on the surface of the filter plate 4 is taken away, thereby achieving the effect of cleaning the surface of the filter plate 4. There is no need to remove the filter plate 4 for cleaning, which saves a lot of time for cleaning the filter screen, reduces the cleaning steps of the filter screen, and improves the cleaning efficiency of the filter screen. At the same time, the cleaned dust falls into the collection tank 5, and the dust is collected by the collection tank 5. When the filter plate 4 needs to be replaced, the cleaning plate 305 is replaced by the cleaning plate 305. The handle 401 is pulled downward by manpower, and the filter plate 4 is driven to move downward by the handle 401, and the block 404 is pushed inward. The block 404 moves inward and squeezes the elastic member 403, thereby releasing the restriction of the elastic member 403 on the filter plate 4. At this time, a new filter plate 4 is inserted into it, and the block 404 is pushed outward by the elastic member 403. The block 404 is engaged with the grooves on both sides of the filter plate 4 to fix the filter plate 4. At the same time, the filter plate 4 is adsorbed by the suction force of the magnetic block 402, thereby preventing the filter plate 4 from being fully inserted therein, resulting in the block 404 not being engaged with the filter plate 4. The position of the filter plate 4 is fixed, and the filter plate 4 can be quickly replaced by pulling and pulling, thereby improving the replacement effect of the filter plate 4.
