[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a spray system for a cleaning machine, including a cleaning box body 1. The inside of the cleaning box body 1 is connected to the top of the first motor 2 through bolt cooperation. The first motor 2 is located on the right side of the first partition 10. The output end of the first motor 2 is connected to one end of the connecting shaft 3 through a coupling. The outside of the connecting shaft 3 is fixedly welded with two symmetric first driving wheels 4. A transmission belt 5 is arranged in the annular groove on the side of the first driving wheel 4. The transmission belt 5 connects the first driving wheel 4 and the second driving wheel 8. One end of each of the two water storage cylinders 6 is fixedly welded to the inside of the cleaning box body 1. The inside of the water storage cylinder 6 is hollow. One end of the water storage cylinder 6 is rotatably connected to the connecting pipe 7 through a bearing. The outside of the connecting pipe 7 is fixedly welded with the second driving wheel 8. The other end of the connecting pipe 7 is fixedly welded to the first spray arm 9. A plurality of spray holes are opened on the side of the first spray arm 9. The inside of the connecting pipe 7 is communicated with the first spray arm 9. The outside of the first partition 10 is fixedly welded to the inside of the cleaning box body 1. The outside of the second partition 11 is fixedly welded to the inside of the cleaning box body 1. The bottom surface of the cleaning box body 1 is connected to one end of two symmetric reciprocating lead screws 14 through rotation. A moving block 15 is arranged on the outside of the reciprocating lead screw 14. The side of the moving block 15 is fixedly welded to the second spray arm 16. A plurality of spray holes are opened on the side of the second spray arm 16. The outside of the reciprocating lead screw 14 is fixedly welded with a worm gear 17. The worm gear 17 is meshed with the worm 13. Two symmetric limiting grooves 18 are opened on the side of the second partition 11. The limiting grooves 18 are slidably connected to the second spray arm 16.

[0021] The interior of the cleaning box body 1 is divided into left and right cavities by a first partition 10. The left cavity is the cleaning cavity, and the right cavity is the operation cavity. The first motor 2 and the connecting shaft 3 are both located in the operation cavity. One end of the transmission belt 5 passes through the first partition 10 and is connected to the second transmission wheel 8. By placing the items to be cleaned in the cleaning cavity on one side of the first partition 10 through a placement rack or fixing them, cleaning can be carried out. The first partition 10 and the second partition 11 make the space inside the cleaning box body 1 more compact. At the same time, through the separation, it is convenient to finish cleaning the sprayed cleaning water. The number of the first transmission wheels 4 is two, and the first transmission wheels 4 are respectively located at the upper and lower ends of the connecting shaft 3. The bottom of the connecting shaft 3 is rotationally connected to the upper surface of the cleaning box body 1 through a bearing. The inside of the water storage cylinder 6 is hollow. The top of the water storage cylinder 6 is rotationally connected to one end of the connecting pipe 7 through a sealed bearing. The connecting pipe 7 is internally connected to the inside of the first spray arm 9. By driving the first motor 2, the connecting shaft 3 and the first transmission wheels 4 rotate synchronously. By using the first transmission wheels 4, the transmission belt 5 drives the second transmission wheel 8 to rotate, and further makes the connecting pipe 7 and the second transmission wheel 8 rotate synchronously, so as to realize the rotation of the first spray arm 9 for cleaning. A plurality of spray holes are opened on the sides of the first spray arm 9 and the second spray arm 16, and the spray holes are evenly distributed in a linear array. Through the rotational spraying of the first spray arm 9 and the reciprocating lifting spraying of the second spray arm 16, the cleaning effect of tableware is effectively improved, and the generation of cleaning dead corners is avoided. A matching through hole is opened on the side of the moving block 15, and the moving block 15 is connected to the reciprocating lead screw 14 in a matching manner. The number of the worm wheels 17 is two, and they are located at both ends of the worm 13. The outer diameter size of the worm wheel 17 is adapted to the outer diameter size of the worm 13. The worm 13 is meshed with the two symmetric worm wheels 17. By driving the second motor 12, the worm 13 rotates, and the worm 13 drives the worm wheels 17 on both sides to rotate, so as to make the reciprocating lead screw 14 rotate. Further, the moving block 15 moves up and down reciprocally outside the reciprocating lead screw 14, improving the cleaning efficiency of the cleaning machine.

[0022] Working principle: When in use, the staff places the tableware in the cleaning cavity inside the cleaning box body 1, and then pumps the cleaning water (not shown in the figure) into the inside of the water storage cylinder 6 through a water pipe (not shown in the figure). Subsequently, it enters the inside of the first spray arm 9 through the connecting pipe 7 and sprays out from the spray holes on the first spray arm 9 to achieve the cleaning effect. By driving the first motor 2, the upper and lower first transmission wheels 4 rotate synchronously. By using the first transmission wheels 4 to drive the transmission belt 5, the second transmission wheel 8 rotates synchronously, and further makes the connecting pipe 7 and the first spray arm 9 start to rotate, so as to realize the synchronous rotation of the upper and lower first spray arms 9 for cleaning. In addition, by driving the second motor 12, the worm 13 rotates, and the worm 13 drives the worm wheels 17 on both sides to rotate, so as to make the reciprocating lead screw 14 rotate. Further, the moving block 15 moves up and down reciprocally outside the reciprocating lead screw 14, so that the cleaning water sprays out from the spray holes on the side of the second spray arm 16, effectively improving the cleaning effect of the cleaning machine.
