[0022] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. For the convenience of description, the positional relationship of "front, rear, up, and down" in the following is described as follows: the extension direction of the cleaning device is defined as "front", the retraction direction of the cleaning device is defined as "rear", the front-to-back direction is the horizontal direction, the vertical direction is perpendicular to the horizontal direction, the vertical upward direction is defined as "up", and the vertical downward direction is defined as "down".

[0024] like Figure 1 As shown, the cleaning device of the intelligent toilet of the utility model comprises a mounting seat 10, a cleaning pipe 20, a driving gear 30 and a power mechanism 40. The mounting seat 10 is provided with a sleeve 11 integrally formed therewith. The power mechanism 40 is generally a motor. The motor and the driving gear 30 are both mounted on the mounting seat 10. The driving shaft of the motor is generally connected to the driving gear 30 through a gear set 50. Specifically, the cleaning pipe 20 comprises an outer tube 22 and an inner tube 21. The sleeve 11 and the outer tube 22 are mutually nested and can slide and retract relative to each other in the axial direction. The outer tube 22 and the inner tube 21 are mutually nested and can slide and retract relative to each other in the axial direction. In this embodiment, the inner tube 21 is nested in the outer tube 22, and the outer tube 22 is nested in the sleeve 11. In the retracted state, the sleeve 11, the outer tube 22, and the inner tube 21 are mutually nested to achieve a reduction in the overall length.

[0025] In order to realize the movement of the outer tube and drive the relative movement of the inner tube through its movement, the outer tube 22 of the utility model is provided with a second rack 22a meshed with the driving gear 30, a transmission gear 60 is rotatably provided on the outer tube 22, and the mounting seat 10 and the inner tube 21 are respectively provided with a first rack 12 and a third rack 21a meshed with the transmission gear 60. In this way, when the power mechanism 40 drives the driving gear 30 to rotate, the second rack 22a meshed with the driving gear 30 moves, and the outer tube 22 moves relative to the mounting seat 10. At the same time, under the action of the first rack 12, the transmission gear 60 set on the outer tube 22 rotates, and the third rack 21a meshed with the transmission gear 60 moves, so that the inner tube 21 moves relative to the outer tube 22. In this embodiment, the transmission gear 60 and the driving gear 30 have the same rotation direction, the first rack 12 is set below the transmission gear 60, and the third rack 21a is set above the transmission gear 60.

[0026] In this embodiment, the number of transmission gears is 1, and the third rack and the first rack are respectively arranged in the upper and lower directions of the transmission gear. Of course, the number of transmission gears can also be at least 2, including at least a first transmission gear and a second transmission gear that rotate simultaneously, the first transmission gear meshes with the first rack, and the second transmission gear meshes with the third rack, so that the same function is achieved through the coordinated action of multiple transmission gears.

[0027] In order to reduce the overall thickness of the cleaning device as much as possible, the third rack is preferably arranged at the top of the inner tube, and the transmission gear passes through the cavity of the outer tube and the bottom of the inner tube to mesh with the third rack. In the present embodiment, the water outlet 21c of the cleaning device is arranged on the inner tube 21, and the inner tube 21 is provided with a water inlet 21d and has a water passage connecting the water inlet 21d and the water outlet 21c. The water passage can be directly formed inside the inner tube 21, or the water inlet 21d can be connected to the water outlet 21c through a hose. The number of water inlets 21d is 2, and the transmission gear 60 is arranged in the middle of the outer tube 22 in the left-right direction, and the two water inlets are respectively located on both sides of the transmission gear in the left-right direction. Preferably, in the present embodiment, the mounting seat 10 is integrally formed with the sleeve 11, the second rack 22a is arranged at the bottom of the outer tube 22, and the driving gear 30 passes through the bottom of the sleeve 11 and meshes with the second rack 22a. A mutually cooperating limiting structure is also provided between the sleeve 11 and the outer tube 22, and the limiting structure includes a clamping groove 13 provided on the outer wall of the sleeve 11 and a protrusion 22b provided on the outer tube 22. The clamping groove 13 and the protrusion 22b are correspondingly matched, so that the outer tube is limited by the limiting structure when extending. As for the limiting when retracting, a relatively simple way is to directly set a blocking piece at the rear end of the mounting seat.

[0028] The principle and preferred implementation of the utility model are described above, and the description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that the utility model is not limited to the form disclosed herein, and should not be regarded as the exclusion of other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention of this article through the above teachings or the technology or knowledge of the relevant field.
