[0030] Specific application examples of the utility model:

[0031] The device body 1 is fixed above the garbage pool 6 through the hanging plate 2. The driving gear 5 is driven by the output end of the driving motor to rotate with the vertical plate 41 of the mounting frame 4. The driving gear 5 rotates to drive the driving gear 5 to move on the meshing racks 51, thereby driving the mounting frame 4 to move in the connecting groove 3. During installation, the horizontal plate 42 of the mounting frame 4 is moved out of the connecting groove 3, so that the horizontal plate 42 is conveniently inserted into the first slot 32 provided on the connecting rod 31, so that the connecting rod 31 is connected to the mounting frame 4. After the connection is completed, the mounting frame 4 is moved upward, which is conducive to driving the connecting rod 31 to move into the connecting groove 3.

[0032] The first telescopic assembly 44 can be made of an electric telescopic rod. The two ends of the first telescopic assembly 44 are respectively hinged with the horizontal plate 42 and the vertical plate 41. The horizontal plate 42 is driven to move horizontally in the through slot 43 provided on the vertical plate 41 through the telescopic first telescopic assembly 44, which is conducive to driving the horizontal plate 42 to insert into the first card slot 32 provided on the connecting rod 31. The fixing of the mounting frame 4 and the connecting rod 31 is completed. The slider 45 provided in the through slot 43 and the first slide rail 46 provided on the horizontal plate 42 are slidably connected to each other, which is conducive to ensuring that the horizontal plate 42 and the vertical plate 41 are firmly connected.

[0033] The second telescopic assembly 35 can be made of an electric telescopic rod. When the connecting rod 31 is located in the connecting groove 3, the second telescopic assembly 35 drives the fixing rod 34 to pass through the second clamping groove 33 provided on the connecting rod 31 and abut against the inner wall of the connecting groove 3. The fixing rod 34 supports the connecting rod 31, which is helpful to reduce the force on the mounting frame 4 in the fixed state, thereby avoiding damage to the mounting frame 4.

[0034] The second slot 33 is located at the lower side of the first slot 32 , so that when the fixing rod 34 passes through the second slot 33 , the mounting bracket 4 will not hinder the fixing rod 34 .

[0035] When the connecting rod 31 is located in the connecting groove 3, the connecting pipe 11 provided on the device body 1 just extends into the ventilation duct 21 provided on the hanging plate 2, which is convenient for installation. The ventilation duct 21 and the vent opening opened on the top wall of the garbage pool 6 are connected and matched with each other.

[0036] The first elastic member 36 can be made of a shock absorbing spring. The first elastic member 36 abuts against the connecting rod 31 to prevent the connecting rod 31 from colliding with the inner wall of the connecting groove 3 when extending into the connecting groove 3, thereby causing damage.
