The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

At present, the structure of the intelligent closestool tends to be miniaturized and lightened. The intelligent toilet lid requires a compact internal space, and particularly the height direction requires a smaller size.

For convenience of description, unless otherwise specified, the directions of the upper, lower, left, right, front and rear are all referred to herein as the state of the spray gun 2 in the cleaning device 100 when used in a toilet, and the end of the spray gun 2 where the nozzle 21 is located is the front, and the opposite direction is the rear.

Referring to fig. 1 to 3, a cleaning device 100 according to an embodiment of the present invention is mainly applied to a toilet or an intelligent toilet, and is used as a main carrier of a cleaning function in the intelligent toilet or the toilet. The cleaning device 100 mainly comprises a base 1, a spray gun 2, a guide frame 3, a support frame 4 and a driving assembly. The driving assembly is arranged on the base 1 and used for providing driving force to drive the support frame 4 and the spray gun 2 to move back and forth relative to the guide frame 3.

The base 1 is arranged inside a toilet cover of the intelligent toilet and can be used for providing mounting positions or mounting spaces for the spray gun 2, the guide frame 3, the support frame 4 and the driving assembly.

The spray gun 2 is movably arranged on the base 1 and extends in the front-rear direction so as to be retractable on the base 1.

The front end of the spray gun 2 is provided with an upward nozzle 21. The spray gun 2 sprays a water column through its nozzle 21 to wash the buttocks or lower body of a human body.

Referring to fig. 1, when the spray gun 2 moves backward relative to the base 1, it has a retracted state hidden inside the toilet lid.

Referring to fig. 2, when the spray gun 2 moves forward relative to the base 1, it is at least partially exposed out of the toilet lid to facilitate cleaning of a human body.

Still referring to fig. 1 to 3, the guide frame 3 is mounted on the base 1 and can support the front end of the spray gun 2.

The guide frame 3 is movably sleeved on the spray gun 2, so that the spray gun 2 can slide back and forth in the guide frame 3 to realize back and forth expansion. The leading truck 3 rotates to be connected on base 1, and then at the in-process of spray gun 2 back-and-forth movement, utilizes leading truck 3 to lead and turn to spray gun 2, stabilizes the movement track of spray gun 2 simultaneously.

The support frame 4 is located at the rear side of the guide frame 3 and serves to support the rear end portion of the spray gun 2.

The support frame 4 is fixedly sleeved at the rear end of the spray gun 2 and can drive the spray gun 2 to extend back and forth relative to the guide frame 3.

Referring to fig. 3 and 4, in some embodiments, the base 1 is provided with a vertical guide plate 11. The guide plates 11 extend in the front-rear direction and are distributed on one side of the support frame 4.

Offer the direction spout 12 that extends along the fore-and-aft direction on the deflector 11, the one end of support frame 4 can stretch into this direction spout 12 and slide, and support frame 4 can slide along the extending direction of direction spout 12 about going on promptly, and then utilizes this direction spout 12 to lead the removal of support frame 4 and spray gun 2 to inject the movement track of support frame 4 and spray gun 2.

It will be appreciated that the guide plate 11 may be integrally formed with the base 1 or may be removably attached to the base 1.

The height of the guide chute 12 on the guide plate 11 corresponds to the height of the support frame 4 and the spray gun 2 on the base 1. In some embodiments, the guide chute 12 is disposed at the top edge of the guide plate 11 to reduce the height dimension of the guide plate 11, thereby reducing the material required for manufacturing the guide plate 11 and achieving a reduction in the overall cost.

Referring to fig. 4 in conjunction with fig. 3, in the present embodiment, the guide chute 12 includes a transverse slot segment 121 and an inclined slot segment 122 integrally connected.

The transverse groove section 121 extends in a transverse direction. It will be appreciated that the transverse groove segments 121 may extend horizontally or may be angled to the horizontal.

The inclined groove section 122 extends obliquely forward and downward from the front end of the transverse groove section 121. The transverse groove section 121 and the inclined groove section 122 are in smooth transition.

It should be noted that the height of the supporting frame 4 is not changed or changes slowly when the supporting frame 4 moves on the transverse trough section 121. When the support shelf 4 is moved over the inclined trough section 122, the height of the support shelf 4 changes relatively faster than when it is moved over the transverse trough section 121.

Referring to fig. 5 in conjunction with fig. 3, in some embodiments, the guide chute 12 may also be an arc-shaped chute. The height of the guide chute 12 gradually decreases in the direction from the rear to the front. It will be appreciated that the height of the support 4 gradually decreases as the support 4 moves from back to front on the curved guide runner 12.

Referring to fig. 1 to 3, the driving assembly is connected to the supporting frame 4 and is used for providing a driving force to drive the supporting frame 4 and the spray gun 2 to extend back and forth relative to the guide frame 3 and the base 1.

Referring to fig. 6 in conjunction with fig. 3, the driving assembly includes a driving motor 5, a driving link 6, a driven link 7 and a slider 8.

Wherein, the driving motor 5 is arranged on the base 1 and used for providing a rotary driving force. The driving motor 5 is a forward and reverse rotation motor so as to control the driving motor 5 to perform forward rotation and reverse rotation.

One end of the driving link 6 is fixed on the output shaft of the driving motor 5, that is, the driving link 6 is connected with the output end of the driving motor 5 and can rotate synchronously with the rotation of the output shaft of the driving motor 5.

One end of the driven connecting rod 7 is hinged with the other end of the driving connecting rod 6, and the other end of the driven connecting rod 7 is used for driving the support frame 4 to move back and forth along the guide sliding groove 12.

Referring to fig. 6 in combination with fig. 1 and 2, when the driving motor 5 rotates forward or backward, the driving motor 5 can drive the driving link 6 to rotate forward or backward synchronously, and can also drive the driving link 6 to rotate relative to the driven link 7, so that the driving link 6 and the driven link 7 can perform opening and closing movements which are opened or closed relatively, and further drive the supporting frame 4 to move back and forth along the guiding chute 12.

Still referring to fig. 6, in some embodiments, the plane of the driving link 6 and the driven link 7 is perpendicular to the plane of the guide plate 11 during the opening and closing movement, so that the opening and closing movement of the driving link 6 and the driven link 7 is more stable.

Still referring to fig. 6 in conjunction with fig. 1 to 3, a sliding block 8 is mounted on the base 1 for transmission connection between the driven link 7 and the supporting frame 4. The base 1 is provided with a slide rail 13 extending in the front-rear direction, and the slider 8 is slidably mounted on the slide rail 13.

A hinge 81 is arranged on the side wall of the sliding block 8, one end of the driven connecting rod 7 is hinged with the driving connecting rod 6, and the other end of the driven connecting rod 7 is rotatably connected on the hinge 81, so that the driven connecting rod 7 is hinged with the sliding block 8. Therefore, the driven connecting rod 7 can drive the sliding block 8 to slide back and forth on the base 1 along the sliding rail 13, and further drive the support frame 4 and the spray gun 2 to move back and forth along the guide sliding groove 12.

Referring to fig. 6 in conjunction with fig. 3, in some embodiments, the slider 8 is provided with an elongated through hole 82. The perforations 82 are distributed through the slider 8 in a direction perpendicular to the side walls of the guide plate 11. One end of the support frame 4 passes through the through hole 82 and is slidably connected in the guide chute 12, so that the sliding block 8 and the support frame 4 are linked. When the sliding block 8 slides back and forth on the sliding rail 13, the inner wall of the front side or the rear side of the through hole 82 can abut against the supporting frame 4 to push the supporting frame 4 to move back and forth relative to the base 1.

When the slide block 8 slides forwards along the slide rail 13, the slide block 8 can drive the support frame 4 penetrating through the through hole 82 to synchronously slide forwards, and then the spray gun 2 is driven to slide forwards to be close to the guide frame 3.

When the slide block 8 slides backwards along the slide rail 13, the slide block 8 can drive the support frame 4 penetrating through the through hole 82 to synchronously slide backwards, and then the spray gun 2 is driven to slide backwards to be far away from the guide frame 3.

The length and height of the through hole 82 on the sliding block 8 correspond to the height of the supporting frame 4. Specifically, as the supporting frame 4 moves on the transverse trough section 121 and the inclined trough section 122, the height of the supporting frame 4 changes, and the through hole 82 allows the supporting frame 4 to synchronously move up and down on the through hole 82 so as to correspond to the height of the supporting frame 4 in the guide chute 12.

It should be noted that, the slide block 8 is used for transmission between the driven connecting rod 7 and the supporting frame 4, and the slide block 8 is in sliding fit with the slide rail 13, so that the forward or backward pulling force of the driven connecting rod 7 on the slide block 8 can be converted into the more stable forward or backward pushing force of the slide block 8 on the supporting frame 4, and the movement of the supporting frame 4 is more stable and smooth.

Referring to fig. 7 in conjunction with fig. 3, the lance 2 is a cylindrical structure. The rear end of the spray gun 2 is fixed in the support frame 4, and the front end of the spray gun 2 movably penetrates through the guide frame 3.

The support frame 4 includes a first holster part 41 and a first coupling part 42 integrally connected.

The first gun sleeve part 41 is fixedly sleeved on the spray gun 2. A first through hole 411 for the spray gun 2 to penetrate is formed in the first gun sleeve portion 41, that is, the first gun sleeve portion 41 is fixedly sleeved on the spray gun 2 through the first through hole 411.

In some embodiments, screw holes correspondingly distributed may be formed in the first holster part 41 and the spray gun 2, so that the first holster part 41 is fixed on the outer peripheral wall of the spray gun 2 through screws, thereby achieving the connection and fixation between the support frame 4 and the spray gun 2.

Referring to fig. 7, in some embodiments, a rib 22 is projected from the outer wall of the spray gun 2 and extends in the axial direction thereof. The first sleeve portion 41 has a fixing groove 412 recessed on the inner wall of the first through hole 411 for fitting with the rib portion 22. When the first sleeve portion 41 is fitted over the spray gun 2, the rib portion 22 is limited in the fixing groove 412, so that the spray gun 2 can be prevented from rotating in the first sleeve portion 41.

Still referring to fig. 7 in conjunction with fig. 3, the first coupling portion 42 is formed at one side of the first holster portion 41 in a protruding manner along a radial direction of the first holster portion 41. The first shaft connecting part 42 can pass through the through hole 82 to be in transmission connection with the sliding block 8, so that the synchronous movement of the support frame 4 and the sliding block 8 is realized.

One end of the first shaft connecting part 42 far away from the first holster part 41 can extend into the guide chute 12 to slide. Thereby the motion trail of the first shaft connecting part 42 is guided and limited through the guide chute 12, and further the motion trail of the support frame 4 and the spray gun 2 is guided and limited.

In some embodiments, a circumferential wall of an end of the first coupling portion 42 away from the first holster portion 41 is recessed with a stop ring groove 421 extending along a circumferential direction thereof. The limit ring groove 421 is located in the guide chute 12, and both side walls of the limit ring groove 421 in the axial direction of the first coupling portion 42 are limited on both sides of the guide plate 11. Therefore, the limit ring groove 421 on the first coupling portion 42 is matched with the guide chute 12, so that a stable sliding connection can be formed between the guide chutes 12 on the guide plate 11, and the movement tracks of the support frame 4 and the spray gun 2 are more reliable.

Still referring to fig. 7 in conjunction with fig. 3, the guiding frame 3 includes a second holster part 31 and a second coupling part 32 integrally connected.

The second gun sleeve portion 31 is movably sleeved on the spray gun 2. A second through hole 311 is formed in the second gun sleeve portion 31 for the spray gun 2 to pass through, that is, the second gun sleeve portion 31 is movably sleeved on the spray gun 2 through the second through hole 311.

In some embodiments, a limiting groove 312 matched with the convex edge 22 of the spray gun 2 is recessed on the inner wall of the second through hole 311 of the second gun sleeve portion 31. When the second gun sleeve portion 31 is movably sleeved on the spray gun 2, the rib portion 22 is limited in the limiting groove 312, so that when the spray gun 2 slides back and forth in the second gun sleeve portion 31, the spray gun 2 can be prevented from rotating in the second gun sleeve portion 31.

The second coupling portion 32 is protruded from one side of the second holster portion 31 in a radial direction of the second holster portion 31. Meanwhile, a shaft hole 14 is formed in the base 1, the shaft hole 14 is formed in the front side of the slide rail 13, the second shaft connecting portion 32 is rotatably inserted into the shaft hole 14, and the guide frame 3 is arranged on the front side of the slide rail 13 and the slide block 8. The center line of the shaft hole 14 is the rotation axis of the second coupling portion 32, which is perpendicular to the center line of the lance 2. Therefore, the guide frame 3 can be rotated relative to the base 1, and the guide frame 3 can guide the spray gun 2 and also can steer the spray gun 2, thereby realizing the sliding and rotating of the spray gun 2 relative to the guide frame 3.

In some embodiments, the end surface of the second coupling portion 32 facing the shaft hole 14 is concavely provided with a threaded hole, and is connected with the second coupling portion 32 through a bolt 321 arranged in the shaft hole 14, so that the guide frame 3 is rotatably connected to the shaft hole 14 of the guide plate 11.

The operation trajectory and the movement process of the spray gun 2 in the present embodiment will be specifically described below. It should be noted that in the present embodiment, the height of the guide frame 3 is always lower than that of the support frame 4, so that the front end of the lance 2 can always be arranged obliquely downward.

Referring to fig. 8 and 9, when the spray gun 2 moves forward along with the support frame 4 on the transverse groove section 121 of the guide chute 12, i.e. during the process from the state of fig. 8 to the state of fig. 9, the rear end of the spray gun 2 and the support frame 4 move linearly forward, while the front end of the spray gun 2 slides forward relative to the guide frame 3 and simultaneously moves downward synchronously, so that the whole spray gun 2 can rotate relative to the base 1 along with the guide frame 3, and the spray gun 2 extends forward and turns gradually.

Therefore, when the spray gun 2 moves forward on the transverse groove section 121 of the guide chute 12, the spray gun 2 can slide and rotate relative to the guide frame 3, the transverse extending distance of the spray gun 2 is increased, and meanwhile, the vertical dimension H of the spray gun 2 is gradually increased along with the rotation of the spray gun 2, so that the extending distance in the height direction can be increased.

Referring to fig. 9 and 10, when the lance 2 moves along with the support frame 4 in the inclined groove section 122 of the guide chute 12, i.e. during the process from the state of fig. 9 to the state of fig. 10, the center line direction of the lance 2 can be parallel to the inclined groove section 122, so that the support frame 4 and the lance 2 only slide relative to the guide frame 3 without rotating, and the travel track of the lance 2 is a straight line which is inclined forward and downward. It will be appreciated that the centerline of the lance 2 may also be oriented other than parallel to the inclined trough section 122.

In the linear motion process of the spray gun 2 in the front and lower direction, and when the central line direction of the spray gun 2 is parallel to the inclined groove section 122, the vertical dimension H of the spray gun 2 is not changed, so that the spraying angle of the upper nozzle 21 of the spray gun 2 is kept unchanged, but the extending distance of the spray gun 2 in the height direction can be further increased and prolonged.

The spray gun 2 moves on the transverse groove section 121 along with the support frame 4, and then moves on the inclined groove section 122 in a turning mode, so that the occupied space of the spray gun 2 in the height direction inside the toilet cover can be reduced, the extension distance of the spray gun in the extension state can be long, the scheme of long-distance extension and retraction in a low space is realized, the thinning and miniaturization of the toilet are facilitated, and the extension distance of the spray gun 2 is effectively guaranteed.

It should be noted that when the driving motor 5 is controlled to rotate reversely, the moving track and the moving mode of the spray gun 2 are opposite to the moving process, and are not described herein again.

In the whole movement process of the forward movement of the spray gun 2, the vertical dimension H of the spray gun 2 can be gradually increased, so that the vertical dimension H of the spray gun 2 in a contraction state is smaller, and the vertical dimension H in an extension state is larger. It is advantageous to reduce the space occupied by the spray gun 2 and the cleaning device 100 in the toilet lid and to increase and lengthen the extension distance of the spray gun 2 in the extended state.

Referring to fig. 11, based on the above-mentioned cleaning device 100, an embodiment of the invention further provides an intelligent toilet. The intelligent toilet mainly includes a toilet body (not shown), a toilet lid 200, a seat 300, a lid 400 and a 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 front end of the toilet lid and is hinge-coupled with the toilet lid 200. The lid 400 is disposed over the seat 300 and is hinged to the toilet lid 200. The cleaning device 100 is disposed inside the toilet lid 200, and the cleaning device 100 is the cleaning device 100 described above.

Referring to fig. 11 in conjunction with fig. 1, when the spray gun 2 is in a retracted state, the spray gun 2 is hidden inside the toilet lid 200.

Referring to fig. 11 in conjunction with fig. 2, when the spray gun 2 is in the extended state, the spray gun 2 is exposed out of the toilet lid 200 and extends into the lower portion of the seat 300.

It should be noted that, in the cleaning device 100, the base 1 can be horizontally arranged inside the toilet lid 200, so that the transverse groove section 121 of the guide chute 12 is horizontally arranged. Alternatively, the base 1 may be disposed inside the toilet lid 200 in an inclined manner, so that the transverse groove section 121 of the guide chute 12 is disposed in an inclined manner.
