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 an intelligent toilet or a toilet seat, and is used as a main carrier of a cleaning function of the intelligent toilet or the toilet seat. 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 base 1 is arranged in a toilet cover of the intelligent toilet and can provide mounting positions or mounting spaces for the spray gun 2, the guide frame 3, the support frame 4 and the driving assembly.

The lance 2 is movably disposed on the bed 1 and extends in the front-rear direction. 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. The spray gun 2 can be extended and retracted back and forth relative to the base 1, and when the spray gun 2 moves backwards relative to the base 1, the spray gun has a retracted state hidden inside the toilet lid, as shown in fig. 1; when the spray gun 2 moves forward relative to the base 1, it has an extended state at least partially exposed out of the toilet lid, so as to clean the human body, as shown in fig. 2.

The guide frame 3 is provided on the base 1 and supports the front end portion of the spray gun 2. The guide frame 3 is movably sleeved on the spray gun 2, so that the spray gun 2 can stretch back and forth in the guide frame 3, the spray gun 2 is guided and steered by the guide frame 3, and the movement track of the spray gun 2 is stabilized.

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.

The driving assembly is connected with the support frame 4 and used for providing driving force to drive the support frame 4 and the spray gun 2 to stretch back and forth relative to the guide frame 3.

Referring to fig. 3, the driving assembly includes a first pulley 5, a second pulley 6, a third pulley 7, a belt 8 and a driving motor 9.

Wherein, first band pulley 5 and second band pulley 6 are the interval arrangement in front and back, and second band pulley 6 is located first band pulley 5 front side. The belt 8 is mounted on the first pulley 5 and the second pulley 6 so that the first pulley 5 and the second pulley 6 can be rotated in synchronization by the belt 8. Specifically, the first pulley 5 and the second pulley 6 may be engaged with the inner surface of the belt 8, respectively, to achieve synchronous transmission. The support frame 4 is connected on the top surface of the belt 8, so that the support frame 4 and the spray gun 2 can synchronously move along with the belt 8.

The driving motor 9 is disposed on the base 1 for providing a rotational driving force. As shown in fig. 3, the first pulley 5 is mounted on the output shaft of the drive motor 9, i.e., the first pulley 5 is connected to the output end of the drive motor 9. The driving motor 9 is a forward and reverse rotation motor, and the forward rotation or the reverse rotation of the driving motor 9 can be synchronous forward rotation or reverse rotation of the first belt wheel 5, the belt 8 and the second belt wheel 6. Because the belt 8 is connected with the support frame 4, when the belt 8 rotates forwards or backwards along with the first belt wheel 5 and the second belt wheel 6 synchronously, the belt 8 can drive the support frame 4 and the spray gun 2 to extend and retract back and forth relative to the guide frame 3.

It will be appreciated that the second pulley 6 may be mounted on the output shaft of the driving motor 9, and the above-mentioned functional effects can be achieved.

Still referring to fig. 3, in some embodiments, the third pulley 7 is disposed between the first pulley 5 and the second pulley 6. The third pulley 7 is able to pull the belt 8 open from the inner ring of the belt 8, so that the top of the belt 8 forms a transverse belt segment 81 and an inclined belt segment 82. The transverse belt segments 81 are distributed between the first belt pulley 5 and the third belt pulley 7. The inclined belt segments 82 are distributed between the third pulley 7 and the second pulley 6. The transverse belt segment 81 forms a smooth transition with the oblique belt segment 82 at the third pulley 7. When the support frame 4 moves on the transverse belt segment 81 along with the belt 8, the spray gun 2 can be driven to move forwards horizontally. When the support frame 4 continues to move on the inclined belt section 82 along with the belt 8, the spray gun 2 can be driven to move obliquely forwards and downwards. Thereby realizing the movement track that the spray gun 2 changes from the straight line movement to the oblique line movement.

It should be noted that in some embodiments, the third pulley 7 may not be provided between the first pulley 5 and the second pulley 6. The belt 8 may only form a transverse belt section 81 in the region between the first pulley 5 and the second pulley 6 to carry the spray gun 2 horizontally forward. Or only the inclined band section 82 is formed to move the spray gun 2 obliquely forward and downward.

In some embodiments, a plurality of third pulleys 7 may be further disposed between the first pulley 5 and the second pulley 6, and the plurality of third pulleys 7 are arranged at intervals, so that the belt 8 forms a plurality of belt segments between the first pulley 5 and the second pulley 6, and the plurality of belt segments are sequentially connected to realize different running tracks.

Referring to fig. 3 and 4, a guide plate 11 is erected on one side of the base 1, and the guide plate 11 extends in the front-rear direction. 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, the guide runner 12 includes a transverse channel section 121 and an inclined channel section 122 integrally connected. The transverse groove segments 121 extend in the transverse direction, and the transverse groove segments 121 are distributed corresponding to the transverse belt segments 81 of the belt 8. The inclined groove section 122 extends from the front end of the transverse groove section 121 obliquely forward and downward, and the inclined groove section 122 is distributed corresponding to the inclined belt section 82 of the belt 8. The transverse groove section 121 and the inclined groove section 122 are in smooth transition, and the third pulley 7 is correspondingly arranged at the transition area between the transverse groove section 121 and the inclined groove section 122.

It will be appreciated that in some embodiments in which no third pulley 7 is provided, the guide runner 12 may also comprise only the transverse groove segment 121, or only the inclined groove segment 122, or take other shapes such as a circular arc segment-like structure.

It should be noted that in some embodiments where a plurality of third pulleys 7 are provided, the guide chute 12 may include a plurality of groove segments that correspond one-to-one with a plurality of belt segments formed on the belt 8.

Still referring to fig. 5 and 6 in conjunction with fig. 3, the lance 2 is shown as 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. 6, 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.

Referring to fig. 6 in conjunction with fig. 1 and 3, the first shaft 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 coupling portion 42 may be connected with the belt 8. The top of belt 8 integrated into one piece has a connecting sleeve 83, and this connecting sleeve 83 can supply first hub portion 42 to pass, and this first hub portion 42 rotationally wears to locate in connecting sleeve 83, realizes that support frame 4 is connected with the rotation of belt 8 to make support frame 4 can be along with belt 8 synchronous motion.

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 support frame 4 and the guide chute 12, and the movement tracks of the support frame 4 and the spray gun 2 are more reliable.

Still referring to fig. 5 and 6 in conjunction with fig. 3, the guide 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 for the spray gun 2 to penetrate is formed in the second gun sleeve portion 31, 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 sleeve 13 is arranged on the base 1, the shaft sleeve 13 is arranged on the front side of the second belt wheel 6, the second shaft connecting part 32 is rotatably arranged in the shaft sleeve 13 in a penetrating way, and the guide frame 3 is arranged on the front side of the second belt wheel 6. The centre line of the sleeve 13 is the axis of rotation of the second coupling part 32, which is perpendicular to the centre line of the lance 2. Therefore, the guide frame 3 can be rotated relative to the base 1, and the guide frame 3 can also steer the spray gun 2 in addition to guiding the spray gun 2. I.e. the lance 2 is able to slide and rotate relative to the guide frame 3.

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. 7 to 9, when the spray gun 2 moves forward with the support frame 4 on the transverse belt segment 81 of the belt 8, the support frame 4 moves along the transverse groove segment 121 of the guide chute 12. In the process, namely in the process from the state of fig. 8 to the state of fig. 9, the rear end part of the spray gun 2 and the support frame 4 move forwards linearly, while the front end part of the spray gun 2 slides forwards relative to the guide frame 3 and synchronously moves downwards, so that the whole spray gun 2 can rotate relative to the base 1 along with the guide frame 3, and the steering of the spray gun 2 is realized.

Therefore, when the spray gun 2 moves forwards on the transverse belt segment 81 of the belt 8, the spray gun 2 can slide and rotate relative to the guide frame 3, the transverse extending distance of the spray gun 2 is prolonged, 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 vertical extending distance of the spray gun can be prolonged.

Referring to fig. 9 to 11, when the spray gun 2 moves forward and downward along the inclined band section 82 of the belt 8 with the support frame 4, the support frame 4 moves along the inclined groove section 122 of the guide chute 12. In this process, i.e. in the process from the state of fig. 9 to the state of fig. 11, the center line direction of the spray gun 2 can be arranged parallel to the inclined belt section 82, so that the support frame 4 and the spray gun 2 only slide relative to the guide frame 3 without rotating, and the running track of the spray gun 2 is a straight line which is inclined forward and downward. In the linear motion process of the spray gun 2 which slants forwards and downwards, the vertical dimension H of the spray gun 2 is not changed, so that the spraying angle of the spray nozzle 21 on the spray gun 2 is kept unchanged, and the vertical extending distance of the spray gun 2 can be further increased and prolonged.

The spray gun 2 firstly moves on the transverse belt section 81 and then moves on the inclined belt section 82, so that the occupied space of the spray gun 2 in the height direction inside the toilet cover is reduced, but the extension distance of the spray gun in the extension state is still longer, the scheme of long-distance extension and retraction in a low space is realized, the light and thin toilet is facilitated, and the extension distance of the spray gun 2 is effectively ensured.

It should be noted that when the driving motor 9 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. 12, based on the above-mentioned cleaning device 100, an embodiment of the present invention further provides an intelligent toilet. The intelligent toilet 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. 12 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. 12 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 disposed inside the toilet lid 200, so that the transverse slot segment 121 of the guide chute 12 and the transverse belt segment 81 of the belt 8 are horizontally disposed. Alternatively, the base 1 may be obliquely disposed inside the toilet lid, so that the transverse slot segment 121 of the guide chute 12 and the transverse belt segment 81 of the belt 8 are obliquely disposed. None of the above approaches affect the normal use of the cleaning device 100 in the toilet.

Based on the technical scheme, the embodiment of the utility model provides an at least, following advantage and positive effect have:

in the cleaning device 100 for the toilet bowl according to the embodiment of the present invention, the driving motor 9 is used to cooperate with the first belt pulley 5, the second belt pulley 6 and the belt 8 to provide the front and back telescopic power for the spray gun 2 and the support frame 4; utilize leading truck 3 and support frame 4 to support spray gun 2 jointly simultaneously, and utilize leading truck 3 to guide and turn to spray gun 2, make support frame 4 can drive spray gun 2 and slide and rotate relative leading truck 3, and stabilize the movement track of spray gun 2, be favorable to optimizing belt cleaning device 100's structure, and improve belt cleaning device 100's operating stability and reliability, be favorable to improving the reach of spray gun 2 in the direction of height, be favorable to reducing the space occupation of spray gun 2 and belt cleaning device 100 in the closestool, in order to realize the frivolousization of closestool.
