The cleaning liquid is sprayed on the cleaning roller 56 through the nozzle 53.

[0038] Furthermore, a driving roller 54 and a fourth driving member driving the driving roller 54 are rotatably connected in the cleaning box 5. The cleaning roller 56 abuts against the driving roller 54 after being recovered along with the multi-stage telescopic rod 7. After the cleaning roller 56 is recovered, the driving roller 54 drives the cleaning roller 56 to rotate, and at the same time, the nozzle 53 sprays the cleaning liquid on the cleaning roller 56, so that the cleaning liquid can fully infiltrate the cleaning roller 56.

[0039] Furthermore, an adapter seat 61 is provided between the connecting seat 6 and the multi-stage telescopic rod 7. The connecting seat 6 and the adapter seat 61 are rotatably connected via a damping shaft 62. The adapter seat 61 is fixedly connected to the end of the multi-stage telescopic rod 7. The cleaning box 5 is provided with a rack 55 on the moving path of the connecting seat 6, and the connecting seat 6 is coaxially provided with a gear 63 that can mesh with the rack 55. The length of the rack 55 is the length corresponding to the ninety-degree rotation of the driving gear 63.

The threaded sleeve 73 rotates synchronously with the control screw 72 through the cooperation of the first synchronization groove 721 and the synchronization bar 731, and can slide relatively. The secondary threaded sleeve 73 also rotates synchronously through the cooperation of the second synchronization groove 732 and the synchronization bar 731, and slides relatively. Such repeated arrangement enables the control screw 72 to rotate so that the plurality of threaded sleeves 73 can simultaneously drive the corresponding secondary sleeves 75 to move. The end of the primary sleeve 74 is connected to the adapter 61 .

[0042] Furthermore, the cleaning box 5 is connected to the base frame 21 via a rotating shaft 57 disposed at the bottom. The second driving member 211 is a telescopic cylinder.

[0043] The implementation principle of an intelligent transport robot suitable for patient transfer in the embodiment of the present application is as follows: In the transport state, the first driving member 25 controls the driving rod 24 to rotate, the tail plate 11 rotates downward, and the back plate 12 rotates upward. The patient is transferred to a suitable position.

[0044] In the cleaning state, the first driving member 25 controls the driving rod 24 to rotate, so that the tail plate 11 rotates upward and the back plate 12 rotates downward, so that the patient contact surfaces of the tail plate 11, the back plate 12 and the base plate 2 are all facing the cleaning box 5. Remove the sealing plate 51 to expose the cleaning box 5, and control the multi-stage telescopic rod 7 to extend out of the cleaning box 5 through the third driving member 71 until the cleaning roller 56 contacts the surface of the base plate 2, and repeatedly retract the multi-stage telescopic rod 7 to clean the surface. The cleaning box 5 is rotated by the second driving member 211, thereby driving the cleaning roller 56 to clean the tail plate 11 and the back plate 12. After the cleaning roller 56 is recovered into the cleaning box 5, the cleaning liquid is sprayed on the surface of the cleaning roller 56 through the nozzle 53, and the cleaning roller 56 is rotated by the active roller 54 so that the cleaning roller 56 is fully soaked in the cleaning liquid.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
