[0026] When the rotating block 6 is moved, the rotation of the rotating block 6 can be controlled by adjusting the gear plate 11, and the movement of the rotating block 6 can be used to control the pressurized gas of the contraction cylinder 8 to the air pump 9. Through the pressurization of the air pump 9, the gas can be conveniently discharged through the air outlet 1303, and the collection of objects is facilitated.

[0027] In the embodiment, the inside of the bottom shell 1 is provided with an internal cavity 101, both ends of the bottom shell 1 are provided with movable holes 102, both ends of the bottom wall of the internal cavity 101 are provided with inclined conical blocks 103, and the bottom shell 1 is provided with a collection box 10 on one side. The collection box 10 is hung outside the bottom shell 1 through a hanging head 1001, the air outlet 1303 is directed to one side of the collection box 10, and the conical block 103 is arranged to facilitate the discharge of objects to the center of the internal cavity 101, so that the objects automatically slide into the internal cavity 101 under the action of gravity, and the collection box 10 is conveniently connected through the hanging head 1001.

[0028] In the embodiment, the top of the bottom shell 1 is provided with two moving rails 4, and a placing piece 5 is arranged between the two moving rails 4. The moving rail 4 is provided with a moving groove, and the placing piece 5 is provided with a protruding block penetrating into the moving groove. The protruding block cooperates with the moving groove to make the placing piece 5 slide along the rail, so as to facilitate the adjustment of the position.

[0029] In the embodiment, the rotating block 6 is fixedly connected with a gear block 602, and the other end of the rotating block 6 is provided with a moving slider 601. The air pump 9 is fixedly connected with the moving slider 601. In use, the contraction cylinder 8 increases the pressure of the air pump 9, so as to collect gas in the air pump 9, and ensure that the gas discharged into the rotating roller 13 has a certain pressure, so as to facilitate the stable discharge of the gas. The structure of the one-way valve 802 in the contraction cylinder 8 is known, and will not be described herein.

[0030] In the embodiment, the inner wall of the supporting plate 12 is provided with a gear cavity 1201, and the inner part of the gear cavity 1201 is provided with a driving wheel 1202 and a driven wheel 1203 which are engaged with each other. The driving wheel 1202 is connected with the rotating block 6, and the driven wheel 1203 is connected with the rotating roller 13. Through the connection of the driving wheel 1202 and the driven wheel 1203, the rotation of the rotating block 6 can be transmitted to the transmission of the rotating roller 13, so as to realize the stable rotation of the rotating roller 13.

[0031] In the embodiment, the outside of the rotating roller 13 is provided with a ventilation hole 1301, and the outside of the air pump 9 is provided with an exhaust pipe which is in communication with the ventilation hole 1301. Through the pressurization of the air pump 9, the gas enters the ventilation hole 1301 through the exhaust pipe and is uniformly discharged, thereby enhancing the air blowing effect of the air outlet 1303 outside the rotating roller 13.

[0033] The operating principle is that the bottom shell 1 is used to collect and process objects that fall inside the placement component 5 through the processing structure 3. When cleaning is needed, the handheld block 7 can be moved manually.

[0034] When the handheld block 7 is moved, the gear block 602 and gear plate 11 on the outside of the rotating block 6 mesh, and the rotating block 6 rotates relative to the rotating block 6. After the rotating block 6 rotates, the rotating block 6 inside the support plate 12 drives the driving wheel 1202 and the driven wheel 1203 in sequence through the support plate 12, and then drives the rotating roller 13 to rotate. After the rotating roller 13 rotates, the friction brush 1302 on the outside of the rotating roller 13 rotates and contacts the bottom shell 1 to achieve the function of assisting in cleaning the objects at the bottom of the bottom shell 1.

[0035] While the rotating block 6 rotates, the reciprocating threads on its exterior control the one-way valve 802 to move back and forth, thus inflating the air pump 9. The air pump 9 collects the gas discharged from the shrink cylinder 8. This gas then reaches the rotating roller 13, where the air outlet 1303, in conjunction with the roller 13, assists in cleaning objects inside the bottom shell 1. This allows for easy control of blowing impurities to one side of the collection box 10, improving cleaning efficiency. Furthermore, the one-way valve 802 ensures unidirectional gas flow, preventing backflow and further enhancing the system's stability and reliability.

[0036] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
