[0005] Principle and effect of the technical solution: When using the device, people only need to place the lunch box on the serving plate after eating. At this time, the first gravity sensor drives the serving plate to rotate and the lunch box falls between the two clamping plates. When the serving plate falls between the clamping plates, the second gravity sensor is triggered. The second gravity sensor starts the first motor and the second motor. After the first motor is started, the blade is driven to rotate through the second rotating shaft. After the second motor is started, the first driven gear is driven to rotate through the driving gear. After the first driven gear rotates, it drives the two threaded rods to rotate. After the two threaded rods rotate, they drive the two clamping plates to expand outward by 30°, so that the bottom of the lunch box is opened. In the process of moving the clamping plate, the bottom of the lunch box can be completely cut open with the help of the blade, so that the oil or unfinished food in the lunch box can be poured into the recycling box on one side of the partition plate. When the clamping plate moves to the second deflection section, the clamping plate is driven outward again by the threaded rod, so that the lunch box falls on the other side of the partition plate, thereby realizing the automatic classification and recycling of kitchen waste.

[0006] Furthermore, the clamping plate is composed of a longitudinal plate and a transverse plate rotatably connected to the longitudinal plate, and cams located on both sides of the blade are symmetrically arranged on the second rotating shaft, and each of the cams is located on the movement trajectory of the transverse plate.

[0007] Furthermore, a spring is connected between the longitudinal plate and the transverse plate.

[0008] Through the above arrangement, when the lunch box separates the uneaten food in it, the cam can be used to squeeze the cross plate, and the elastic force of the spring can be used to drive the cross plate to reset. When it is reset, the up and down vibration of the spring can be used to drive the lunch box on the clamping plate to vibrate, which is convenient for accelerating the falling of the food and improving the separation efficiency and effect.

[0010] Through the above arrangement, the driving gear and the second driven gear are used to drive the third rotating shaft to rotate, so that the negative pressure blades can continuously inflate the airbag, so that the airbag can drive the sealing plate to trigger the pressure switch, and the pressure switch can control the battery valve to open, so that a small amount of clean water in the liquid storage tank can be used to clean the clamping plate, thereby keeping the clamping plate clean and hygienic.

[0011] Furthermore, the upper and lower sides of the feed port are both arc-shaped, and the free ends of the holding plates are matched with the upper and lower sides of the feed port. The two symmetrical holding plates and the first rotating shaft can close the feed port.

A water outlet pipe is connected to the bottom of the water storage tank 22. A solenoid valve 24 is installed on the water outlet pipe.

The right end of the third rotating shaft 31 is rotatably connected to the recovery box 1. Four negative pressure blades located at the opening of the airbag 28 are equidistantly distributed on the left side of the third rotating shaft 31 in the circumferential direction. The right end of the third rotating shaft 31 is covered with a second driven gear 32 meshing with the driving gear 20.

[0026] The working process of this scheme is as follows: before using this device, firstly, clean water is filled into the water storage tank 22 by means of the water inlet pipe 23. At this time, the two receiving plates 5 seal the feed port, thereby preventing the odor in the recycling box 1 from being transmitted and polluting the environment. After finishing the meal, people place the lunch box on the receiving plate 5. At this time, the first gravity sensor is triggered to start the stepper motor 3. After the stepper motor 3 is started, it can drive the receiving plate 5 to rotate, so that the lunch box slides onto the two horizontal plates 10. The baffle 12 on the horizontal plate 10 can be used to prevent the lunch box from sliding out of the horizontal plate 10, thereby maintaining the stability of this device.

[0027] When the plate 5 falls on the horizontal plate 10, the second gravity sensor is triggered. After the second gravity sensor is triggered, the first motor 18 and the second motor 19 are started. After the first motor 18 is started, the blade 14 and the cam 15 are driven to rotate through the second rotating shaft 13. After the second motor 19 is started, the first driven gear 16 is driven to rotate through the driving gear 20. After the first driven gear 16 rotates, the two threaded rods 8 are driven to rotate. After the two threaded rods 8 rotate, the two clamping plates are driven to expand outward by 30°. At this time, the two horizontal plates 10 are separated and the bottom of the lunch box is opened. When the clamping plates cannot be expanded outward, they start to move to the right side, so that the bottom of the lunch box can be completely cut open with the help of the blade 14, so that the oil or unfinished food in the lunch box can be poured into the recycling box 1 on the side of the partition plate 17. During the operation of the blade 14, the cam 15 can also drive the two horizontal plates 10 to move intermittently toward the longitudinal plate 9, so that the vibration of the horizontal plate 10 can be realized in the switching process of compression and reset with the help of the first spring 11, which accelerates the speed of food falling.

[0028] When the clamping plate moves to the second deflection section 7, the clamping plate is again extended outwards driven by the threaded rod 8. At this time, the clamping plate is located on the right side of the partition plate 17, so that the lunch box falls on the right side of the partition plate 17, thereby realizing automatic classification and recycling of kitchen waste. When the horizontal plate 10 of the clamping plate touches the pressure sensor 21, the second motor 19 starts to rotate in the opposite direction to drive the clamping plate to reset. When the clamping plate hits the first pressure switch, the second motor 19 is turned off and the clamping plate stops moving.

[0029] During the resetting process of the clamping plate, after the second motor 19 is started, it will drive the second driven gear 32 to rotate with the help of the driving gear 20, so that the third rotating shaft 31 drives the negative pressure blade to continuously inflate the airbag 28. After the airbag 28 is inflated, it can move in the direction of extension of the second spring 29, thereby driving the sealing plate 30 to move and triggering the second pressure switch 26. At this time, the solenoid valve 24 is opened, and the clean water in the water tank 22 is sprayed out from the nozzle 25, thereby achieving the cleaning of the clamping plate.

It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
