[0044] For details, please refer to Figure 4 A guide frame 56 is fixedly provided on the rear side of the support plate 51. The interior of the guide frame 56 is a rectangular cavity structure. A guide rail 57 communicating with the interior of the guide frame 56 is opened on the rear side of the guide frame 56. The interior of the guide frame 56 and the guide frame 56 slide linearly left and right along the fixed frame 52, that is, the front end of the fixed frame 52 is a T-shaped structure matching the interior of the guide frame 56 and the guide frame 56. When the water bucket 4 needs to be taken out, the support plate 51 can be moved outward at the front end of the fixed frame 52 through the guide frame 56 to be dislocated and separated from the front end of the water bucket 4, so that the water bucket 4 can be drawn out from the front end of the cylinder body 21 to avoid obstruction. After the new water bucket 4 is installed, the support plate 51 can be slid and reset.
[0045] For further information, please refer to Figure 5 The rotating assembly 6 includes a ring gear 61, a gear 62, a first motor 63 and a mounting plate 64. The ring gear 61 is coaxially fixed to the outside of the cylinder 21, and the outer side of the gear 62 is meshed with the ring gear 61. The output shaft of the first motor 63 is coaxially fixed to the gear 62, and the outer side of the first motor 63 is fixed to the frame 1 through the mounting plate 64, so that the gear 62 drives the ring gear 61 to rotate through the rotation of the first motor 63, so that the cylinder 21 can rotate, driving the bucket 4 to rotate synchronously.
[0046] Please refer to Figure 2The disinfection assembly 7 includes an infusion tube 71, a first joint 72, a second joint 73, a liquid extraction tube 74, a liquid extraction hose 75, a joint hose 76 and a block 77. The first joint 72 and the second joint 73 are fixedly provided on the outside of the infusion tube 71. The outer end of the liquid extraction tube 74 is fixed to the first joint 72. The liquid extraction tube 74 is coaxially arranged inside the infusion tube 71. The second joint 73 is communicated with the inside of the infusion tube 71. The liquid extraction hose 75 is fixedly arranged on the inner end of the liquid extraction tube 74. The joint hose 76 is fixedly mounted on the first joint At the outer ends of the first joint 72 and the second joint 73, the pipeline for externally extracting disinfectant and the pipeline for inputting disinfectant are respectively connected to the first joint 72 and the second joint 73 through the joint hose 76, so that the disinfectant is injected into the infusion tube 71 through the second joint 73. When extracting liquid, the disinfectant is extracted from the first joint 72 through the extraction tube 74 and the extraction hose 75. A blocking block 77 is rotatably installed on the outer wall of the infusion tube 71 to stop the water inlet of the bucket 4 through the blocking block 77, so as to facilitate the disinfection and sealing of the inside of the bucket 4.
[0047] During implementation, the inner ends of the infusion tube 71 and the extraction tube 74 are both inserted into the water bucket 4, and the extraction hose 75 is located inside the water bucket 4. The end of the extraction hose 75 contacts the bottom of the water bucket 4 through its own weight, so that during disinfection, the disinfectant is input into the water bucket 4 through the infusion tube 71. Since the water bucket 4 is in a horizontal position, the disinfectant only needs to be injected until it covers half of the volume of the water bucket 4. When the water bucket 4 rotates, the disinfectant is inconveniently positioned due to its own weight, and the rotating water bucket 4 can make its internal circulation contact with the disinfectant, so as to save disinfectant while meeting the needs of quick disinfection of the water bucket 4. The block 77 is an overall conical structure, and the outer wall of the block 77 fits with the inner wall of the water inlet of the water bucket 4. The material of the block 77 is rubber, which has strong elasticity and fits with the water inlet of the water bucket 4, so that when the water bucket 4 rotates, the block 77 rotates synchronously with the water bucket 4 and prevents leakage of the disinfectant.
[0048] Furthermore, the moving assembly 8 includes a frame 81, a second screw rod 82, a support frame 83 and a second motor 84. The top of the frame 81 is fixed to the infusion tube 71, and the bottom of the frame 81 is threadedly connected to the second screw rod 82. The outer side of the frame 81 slides linearly along the support frame 83. The second motor 84 is fixed to the outer side of the support frame 83, and the output shaft of the second motor 84 is coaxially fixed with the second screw rod 82. The front and rear ends of the second screw rod 82 are rotatably connected to the support frame 83, so that the second screw rod 82 can be driven to rotate by the rotation of the second motor 84, so that the frame 81 can drive the infusion tube 71 to move forward or backward after receiving the spiral thrust of the second screw rod 82, so that the infusion tube 71 can be separated from the bucket 4 after the water bucket 4 is disinfected, and after the new water bucket 4 is installed, the infusion tube 71 is reset and connected to the bucket 4 for disinfection.
[0049] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and wiring arrangement in detail.
[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
