To make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, and only illustrates the basic structure of the present invention in a schematic manner, and therefore it only shows the constitution related to the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Specifically, referring to fig. 2, the limiting mechanism 3 includes a limiting switch 31 disposed beside the cleaning mechanism 2, and a limiting block 32 disposed at one side of the nut 24. The limiting block 32 is shaped like a Chinese character 'ao', and the limiting switch 31 is positioned at the sunken part in the middle of the limiting block 32. When the stopper 32 moves, it touches the limit switch 31. The limit switch 31 includes a first switch 311 located at an upper portion and a second switch 312 located at a lower portion.

Specifically, referring to fig. 2-3, the cleaning mechanism 2 includes a motor 21, a deceleration system 22 disposed at a bottom end of the motor 21, a screw 23 connected to the deceleration system 22, a nut 24 sleeved outside the screw 23, an outer tube 25 sleeved outside the screw 23, a cavity 251 disposed in the outer tube 25, and nozzles 26 disposed around a lower portion of the outer tube 25. The motor shaft of the motor 21 extends into the speed reducing system 22 and is meshed with the multi-stage speed reducing gears in the speed reducing system 22, and when the motor 21 is started, the rotating speed of the motor shaft is gradually reduced to drive the screw rod 23 to rotate slowly through the speed reducing system 22. When the screw 23 rotates along the thread direction, the nut 24 is driven to move upwards, and when the screw 23 rotates against the thread direction, the nut 24 is driven to move downwards.

An outer tube 25 of the cleaning mechanism 2 is a cylindrical tube, and threads matched with the screw rod 23 are arranged inside the outer tube 25. When the nut 24 moves up and down, the outer tube 25 also moves along with the nut 24. When the nut 24 moves upward until the stopper 32 reaches the first switch 311, the motor 21 stops rotating and the cleaning mechanism 2 stops moving at the same time. When the outer tube 25 needs to move downwards, the screw rod 23 rotates towards the reverse thread direction through the introduction of reverse current and the power transmission of the gear, the nut 24 drives the outer tube 25 to gradually move downwards to the second switch 312, and after the limiting block 32 touches the second switch 312, the motor 21 stops rotating, and the cleaning mechanism 2 stops moving.

When the cleaning mechanism 2 is required to perform cleaning operation, cleaning liquid is injected into the cavity 251 in the cleaning mechanism 2, the cleaning liquid enters the nozzles 26 through the cavity 251, and the nozzles 26 arranged around the cleaning mechanism 2 uniformly spray the cleaning liquid onto the inner wall of the dryer to clean the dryer.

Specifically, referring to fig. 1-2, the atomizer 4 includes an atomizing motor 41, a speed increasing system 42 connected to a motor shaft of the atomizing motor 41, a main shaft connected to the speed increasing system 42, and an atomizing disk 43 disposed at one end of the main shaft. When the atomizer 4 is required to work, the atomizing motor 41 is started to drive the motor shaft to rotate, the main shaft is enabled to rotate at a high speed through multi-stage acceleration, the atomizing disc 43 is driven to rotate at a high speed, and the feed liquid entering the atomizer 4 can be thrown out through a plurality of dense and fine atomizing holes in the atomizing disc 43 under the action of centrifugal force.

Specifically, referring to fig. 1, the cross-section of the housing 1 is a straight oval shape with two sides, the width of the oval is slightly larger than the diameter of the nut 24, and when the cleaning mechanism 2 is fully retracted, the lower end of the housing 1 is above the nozzle 26.

When the atomization and cleaning integrated device 100 works, the cleaning mechanism 2 is in a completely withdrawing state at the beginning, when the atomization process is needed, the atomization motor 41 is started, the motor shaft of the atomization motor 41 starts to rotate, the speed increasing system 42 can be driven to start to operate due to the fact that the motor shaft is meshed with the gear in the speed increasing system 42, the atomization disc 43 is driven to operate at a high speed through the multistage speed increasing of the gear in the speed increasing system 42, and the feed liquid entering the atomizer 4 is atomized into fog drops.

Alternatively, the structure of the atomizer 5 can refer to CN103463825A, a centrifugal atomizer.

When the atomization process is finished and the cleaning process needs to be performed, the atomization motor 41 stops operating, the motor 21 is started, the motor shaft of the motor 21 is connected with the speed reduction system 22, the rotating speed of the screw rod 23 is reduced through multi-stage speed reduction of the gear of the speed reduction system 22, the screw rod 23 rotates in the direction of reverse threads, the outer pipe 25 of the cleaning mechanism 2 moves downwards, when the limiting block 32 moves downwards to the second switch 312, the cleaning mechanism 2 stops operating, and cleaning liquid in the cavity 251 of the cleaning mechanism 2 is sprayed out through the nozzle 26 to clean the inner wall. After the cleaning is finished, the cleaning mechanism 2 is reset.
