The upper surface of the flat base 220 is a plane, so that the garbage can stably move in the horizontal direction, the upper surfaces of the first inclined base 210 and the second inclined base 230 are inclined planes, the higher side of the inclined bases is connected with the flat base 220, and the lower side of the inclined bases is arranged back to the flat base 220, so that the garbage can be conveniently put in and taken out.

The cleaning bin 1 is arranged along the length direction of the flat bottom seat 220, and is formed by overlapping a plurality of inverted U-shaped shells along the length direction of the flat bottom seat 220. The front side of the washing cartridge 1 (i.e. the right side as shown in fig. 1) is the inlet opening 101 and the rear side of the washing cartridge 1 is the outlet opening. A conveyor belt 260 is provided on the base below the surface of the flat bottom base 220 and the first and second angled bases 210, 230 for conveying the trash can from the first angled base 210 on the front side of the base to the second angled base 230 on the rear side. In another more preferred embodiment, conveyor belt 260 employs a conveyor chain. The prior art is adopted to drive the conveying belt 260 or the conveying chain to run and to support the conveying belt 260 and the conveying chain to keep stable in long distance, and the prior art is adopted to arrange corresponding grooves on the flat bottom seat 220, the first inclined seat 210 and the second inclined seat 230 to expose the conveying belt 260 for placing garbage cans and other structures, and meanwhile, the above technology is not the essential point of the utility model, so that the description is omitted.

The first cleaning unit 110, the second cleaning unit 120, and the third cleaning unit 130 are sequentially arranged at intervals along the conveying direction (the entrance 101→the exit) of the conveyor belt 260, and preferably, the distance between the first cleaning unit 110 and the second cleaning unit 120 is not less than 50cm, and the distance between the second cleaning unit 120 and the first cleaning unit 110 is not less than 50cm.

Referring to fig. 3 and 4, the first cleaning unit 110, the second cleaning unit 120, and the third cleaning unit 130 have the same basic structure, and each of them includes a plurality of high-pressure nozzles distributed on the top, bottom, and side walls of the cleaning bin 1 and water supply pipes for supplying water to the high-pressure nozzles. In this embodiment, the first cleaning unit 110 is used to wet and soak the trash can, and the dirt on the surface of the trash can is softened by pre-wetting and soaking for a certain period of time, so as to facilitate washing. The second cleaning unit 120 is mainly used for cleaning dirt and stains by impact, so that the spraying flow of the first high-pressure nozzle 111 of the first cleaning unit 110 is larger than that of the second high-pressure nozzle 121 of the second cleaning unit 120, and the spraying pressure is smaller than that of the second high-pressure nozzle 121 of the second cleaning unit 120.

And, the positions of the high-pressure nozzles 111 on the middle pipe or the water supply pipe can be different from each other.

In this way, the wetting range of the first cleaning unit 110 can be enlarged, and the garbage can be soaked for a longer time in the process that the conveying belt 260 drives the garbage can to move, so that the dirt on the garbage can be fully softened and wetted under the limited space and time range, and the second cleaning can be conveniently performed by single flushing.

Thus, the high pressure nozzles of the second and third cleaning units 120 and 130 may be intensively distributed on one vertical plane with the transfer direction of the transfer unit. Specifically, referring to fig. 4, each of the second and third cleaning units 120 and 130 includes only a rectangular water supply structure formed in a single-layered structure using a single-turn water supply pipe, which communicates with the water pump 4 through a water supply pipe. The water supply pipe is distributed with a plurality of first high-pressure nozzles 111 or second high-pressure nozzles 121.

In addition, a control cabinet and a water pump 4 are additionally arranged, the water inlet side of the water pump 4 is communicated with a municipal water supply official network or is communicated with a water tank, the water tank is communicated with the municipal water supply official network, and the water outlet side of the water pump 4 is respectively communicated with and supplies water for the first cleaning unit 110, the second cleaning unit 120 and the third cleaning unit 130 through a first water supply pipe 41, a second water supply pipe and a third water supply pipe 43. If a water tank is arranged, an electromagnetic valve and an electronic water level detector can be arranged to avoid the too high or too low water level in the water tank.

To improve the cleaning effect, a heater may be provided in the tank for increasing the temperature of the rinse water to improve the wetting and soaking effects.

The control cabinet comprises a controller, wherein the input end of the controller is electrically connected with a temperature sensor (arranged in a water tank for detecting the temperature), a heater and an electronic water level detector, and the output end of the controller is communicated with a motor and an electromagnetic valve for controlling the movement of the conveying belt 260, so that the functions of automatic operation, automatic water supplementing, automatic heating and the like of the conveying belt 260 can be realized, and the automatic assembly line for cleaning the 3-section garbage can is further realized, so that the automatic control cabinet is convenient to use in practice.

The present embodiment uses the following: the garbage inlet of the garbage can (i.e. the opening at the top of the garbage can) is downward placed on the conveyer belt 260 exposed from the inclined surface of the first inclined base 210, and the conveyer belt 260 is used for being linked with the garbage can and driving the garbage can to enter the cleaning bin 1 and sequentially pass through the first cleaning unit 110, the second cleaning unit 120 and the third cleaning unit 130. The first cleaning unit 110 sprays water or cleaning liquid with high flow rate and low pressure on the inner and outer side walls and the bottom of the garbage can to soak dirt, the second cleaning unit 120 sprays water with high pressure to perform a dirt removing function, and the third cleaning and rinsing unit rinses the passing garbage can.
