As shown in fig. 1, in the cleaning apparatus 100 of the present embodiment, before the cleaning operation, the support frame 30 is relatively close to the driving motor 41 together with the spray gun 20. At this time, the lance 20 is disposed to be inclined with respect to the base 10, and the vertical dimension occupied by the lance 20 in the space in the height direction is H.

When the driving motor 41 is operated, the driving teeth 421 and the wheel 42 are rotated, and the rack portion 432 is moved forward by the engagement of the interlocking teeth 4321 with the driving teeth 421, so that the slider 43 is moved forward. The movement of the slide 43 moves the support 30 and thus the spray gun 20 relative to the base 10. In the moving process of the spray gun 20, the limit protrusion 3211 on the support frame 30 is limited in the guide chute 121, so that the moving track of the spray gun 20 is consistent with the trend of the guide chute 121.

When the lance 20 moves along the guide chute 121, the lance 20 first moves in the transverse groove section 1211, i.e., translates forward relative to the base 10. The distance that lance 20 projects laterally is progressively longer in this case, but the vertical dimension H of lance 20 is unchanged. When the lance 20 and the support frame 30 move in the guide chute 121 in the transition area between the transverse groove section 1211 and the inclined groove section 1212, the vertical dimension H of the lance 20 becomes larger and its projecting distance in the height direction becomes longer.

When the spray gun 20 moves along with the support 30 in the inclined groove section 1212 of the guide chute 121, the support 30 and the spray gun 20 only make a translational motion downwards relative to the base 10. At this time, the vertical dimension H of the lance 20 is not changed any more, but the distance it projects in the height direction becomes long. Until the final extended state is reached, as shown in fig. 2.

When the driving motor 41 drives the driving gear 421 and the gear 42 to rotate reversely, the movement track and the movement form of the spray gun 20 are opposite to those of the above situation, and the spray gun 20 is retracted after the cleaning operation is completed.

Through the setting of the guide chute 121, the spray gun 20 moves on the transverse groove section 1211 along with the support frame 30, and then moves on the inclined groove section 1212, so that the extended distance is relatively long under the condition of ensuring the extended state, the occupation of the spray gun 20 in the space in the height direction inside the toilet lid 200 can be reduced, the purpose of relatively long-distance extension and retraction of the spray gun 20 in a low space is achieved, and the design of lightening, thinning and miniaturization of the intelligent toilet is favorably realized.

Further, as shown in fig. 7, an embodiment of the present application further provides an intelligent toilet. The intelligent toilet comprises a toilet body, a toilet cover 200, a seat ring 300, a flip cover 400 and the cleaning device 100.

Wherein, the toilet lid 200 is disposed on the top of the toilet body. The seat 300 is provided on the top surface of the toilet lid 200 and is rotatable with respect to the toilet lid 200. The lid 400 is disposed above the seat 300 and can rotate with respect to the toilet lid 200. The cleaning device 100 is disposed inside the toilet lid 200, and the base 10 of the cleaning device 100 is fixed to the toilet lid 200.

When the spray gun 20 of the cleaning device 100 is in the extended state, the spray gun 20 is exposed out of the toilet lid 200 and extends into the lower portion of the seat 300 to perform the cleaning function. When the spray gun 20 is in the retracted state, the spray gun 20 is hidden inside the toilet lid 200.

To the belt cleaning device and intelligent closestool for closestool of this embodiment, the spray gun is overall structure, through the cooperation of driving motor, drive gear and slider, can provide the power of back-and-forth movement for support frame and spray gun, realizes stretching out or packing up of spray gun.
