A square plug 43 slidably connected to the inner wall of the moving block 13 is fixedly installed at one end of the moving block 13 located in the square cylinder 12. A first fixing member 43 is fixedly connected between the square plug 43 and the inner wall of the square cylinder 12 close to the round box 16. The second spring 44 is provided on the square tube 12 with a second connecting tube 7 and a third connecting tube 11 connected to the inside thereof. The ends of the second connecting tube 7 and the third connecting tube 11 connected to the square tube 12 are both located on the side of the square plug 43 away from the moving block 13. The end of the second connecting tube 7 away from the square tube 12 is connected to the box body 3. The end of the third connecting tube 11 away from the square tube 12 is connected to another conveying tube 34. The other conveying tube 34 is provided with a seventh connecting tube 35 connected to the inside thereof. The third connecting tube 11 and the seventh connecting tube 35 are connected to the square tube 12. One end connected to the other conveying cylinder 34 is located outside the two conveying plugs 37. A heating box 10 is arranged on the top of the box body 1. One end of the seventh connecting pipe 35 away from the other conveying cylinder 34 is connected to the heating box 10. One-way valves are arranged in the first connecting pipe 6, the third connecting pipe 11, the fourth connecting pipe 14, the fifth connecting pipe 15, the sixth connecting pipe 19 and the seventh connecting pipe 35. The second connecting pipe 7 is provided with a first control valve 5. The arc groove 39 extends along the axial direction of the lifting column 38, and the moving block 13 is in the shape of a right-angle trapezoid.

[0038] When the present invention is used, one end of the fourth connecting pipe 14 away from the round box 16 is connected to a container for storing clean water, and one end of the fifth connecting pipe 15 away from the round box 16 is connected to a container for storing disinfectant washing liquid. A plastic container is placed in the barrel body 2. In the initial state, the valves of the first control valve 5 and the second control valve 9 are both in a closed state, the sixth connecting pipe 19 is connected to the fifth connecting pipe 15 but not to the fourth connecting pipe 14, and the control rod 33 is passed through the first frame 31 and the second frame 32 (as shown in the attached figure) by the cylinder 30. Figure 3 As shown), the motor 28 is started at this time, and the output shaft of the motor 28 drives the second toothed disc 29 to rotate. By setting the first toothed disc 27, the mixing drum 46 can be rotated, that is, the second rotating shaft 24 and the mixing rod 23 rotate around the axis direction of the mixing drum 46;

[0039] When the second toothed disc 29 rotates, the cylinder 30 and the control rod 33 rotate around the axis of the second toothed disc 29, and the control rod 33 slides in the first frame 31, so that the first frame 31 swings left and right, and then the first rotating shaft 22 rotates left and right, so that the swing rod 4 and the first bevel gear 25 rotate back and forth left and right. By setting the second bevel gear 26, the stirring rod 23 can rotate around the axis of the second rotating shaft 24, so that the stirring rod 23 can rotate while revolving. Through the joint action of the stirring rod 23 and the swing rod 4, the vessel placed in the barrel 2 can be fully stirred for subsequent disinfection, cleaning and drying.

[0040] When the control rod 33 rotates around the axis of the second toothed disc 29, the control rod 33 will also slide in the second frame 32, so that the second frame 32 moves left and right, and then the two delivery plugs 37 slide left and right in the two delivery cylinders 34 respectively. When the delivery plugs 37 slide in the direction close to the second toothed disc 29, the disinfectant washing liquid will be sucked into one of the delivery cylinders 34 through the fifth connecting pipe 15 and the sixth connecting pipe 19, and the hot air heated by the heating box 10 will be sucked into the other delivery cylinder 34 through the seventh connecting pipe 35. When the delivery plug 37 moves in the direction away from the second toothed disc 29, the disinfectant washing liquid in one delivery cylinder 34 will be squeezed into the box body 3 through the first connecting pipe 6 and sprayed from the nozzle 45 to the vessel in the barrel body 2, and the stirring of the stirring rod 23 and the swing rod 4 will be coordinated to achieve the disinfection and washing of the vessel, while the hot air in the other delivery cylinder 34 will be squeezed into the square cylinder 12 through the third connecting pipe 11. Since the valve of the first control valve 5 is in the closed state, the square plug 43 and the moving block 13 will move in the direction close to the round box 16 ( Figure 1 The second spring 44 is compressed, and the process repeats like this;

[0041] After a period of time, the utensils are sterilized and washed, the inclined surface on the moving block 13 will contact the curved surface of the convex cap 20, and as the moving block 13 continues to move, the convex cap 20, the connecting rod 21 and the lifting column 38 move downward, the first spring 18 is compressed, and the slider 42 slides in the arc groove 39, so that the rotating cylinder 40 and the two conversion blocks 41 can rotate clockwise by a certain angle, and the convex cap 20 moves downward and finally contacts the bottom of the moving block 13, and the convex cap 20, the connecting rod 21 and the lifting column 38 are at the lowest position, and the positions of the rotating cylinder 40 and the conversion blocks 41 are as shown in the attached figure. Fig. 9 As shown, the sixth connecting pipe 19 is connected to the fourth connecting pipe 14 but not to the fifth connecting pipe 15. At this time, the motor 28 is turned off and the second control valve 9 is opened to discharge the disinfectant washing liquid in the barrel 2;

[0042] After the washing liquid is discharged, the motor 28 is started again. At this time, the clean water will be sucked into one of the conveying cylinders 34 through the fourth connecting pipe 14 and the sixth connecting pipe 19 and finally sprayed to the utensils in the barrel body 2 through the first connecting pipe 6, the box body 3 and the nozzle 45 for cleaning. The hot air will still be squeezed into the square tube 12, so that the square plug 43 and the moving block 13 continue to move to the right. During this process, the convex cap 20 will not move downward. After the utensils are cleaned, the second control valve 9 is opened again to discharge the washing water in the barrel body 2, and the control rod 33 is moved upward and away from the second frame body 32 through the cylinder 30. At this time, through The motor 28 cannot move the second frame 32 left and right, but can still swing the first frame 31 to fully stir the vessel in the barrel 2. The valve of the first control valve 5 is opened, and the elastic force generated by the compression of the second spring 44 causes the square plug 43 and the moving block 13 to return to the initial position to the left. The hot air in the square cylinder 12 is squeezed into the box body 3 through the second connecting pipe 7 and sprayed from the nozzle 45 to the stirred vessel, accelerating the drying of the vessel. After the vessel is dried faster, the control rod 33 passes through the second frame 32 again through the cylinder 30, and the motor 28 is turned off, and finally the vessel in the barrel 2 is taken out;

[0043] The moving block 13 that moves leftward back to the initial position will eventually no longer be in contact with the convex cap 20. The elastic force generated by the compression of the first spring 18 can cause the lifting column 38 to move upward, thereby causing the rotating cylinder 40 and the conversion block 41 to rotate counterclockwise, thereby causing the sixth connecting tube 19 to be connected to the fifth connecting tube 15 again instead of being connected to the fourth connecting tube 14.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
