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 support frame 3 and a driving assembly. The driving assembly is arranged on the base 1 and used for providing driving force to drive the support frame 3 and the spray gun 2 to stretch back and forth relative to the base 1.

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 support frame 3 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 supporting frame 3 is movably disposed on the base 1 and is used for supporting the spray gun 2.

The support frame 3 is fixedly sleeved on the spray gun 2 and can drive the spray gun 2 to extend back and forth relative to the base 1 so as to extend out or retract into the toilet lid.

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 3.

Offer the direction spout 12 that extends along the fore-and-aft direction on the deflector 11, the one end of support frame 3 can stretch into this direction spout 12 and slide, and support frame 3 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 3 and spray gun 2 to inject the movement track of support frame 3 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 3 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 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.

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

Referring to fig. 5 and 6 in conjunction with fig. 3, the driving assembly includes a driving motor 4, a driving gear 5, a first winding wheel 61, a second winding wheel 62, a driving rope 7, a fixed pulley 8 and a sliding block 9.

Wherein, the driving motor 4 is arranged on the base 1 and used for providing a rotary driving force. The driving motor 4 is a forward and reverse rotation motor so as to control the driving motor 4 to perform forward rotation and reverse rotation.

In some embodiments, a stand 15 is provided on the base 1. The driving motor 4 is fixed on the stand 15, and an output shaft of the driving motor 4 can be perpendicular to the side wall of the guide plate 11, so that the output shaft of the driving motor 4 is perpendicular to the guide chute 12.

The driving gear 5 is disposed on the output shaft of the driving motor 4, that is, the driving gear 5 is connected to the output end of the driving motor 4 and can rotate synchronously with the rotation of the output shaft of the driving motor 4. It is understood that a gear assembly may be provided on the output shaft of the driving motor 4 or between the output shaft of the driving motor 4 and the driving gear 5 to change the speed of the rotational driving force output from the driving motor 4 and output the rotational driving force with different rotational speeds.

The first winding wheel 61 and the second winding wheel 62 are respectively connected to the base 1 in a rotating manner and meshed with the driving gear 5, so that the driving motor 4 can drive the first winding wheel 61 and the second winding wheel 62 to rotate synchronously through the rotation of the driving gear 5.

Referring to fig. 6, in some embodiments, the first winding wheel 61 is provided with a first gear portion 611, the first winding wheel 61 can be engaged with the driving gear 5 through the first gear portion 611, the second winding wheel 62 is provided with a second gear portion 621, and the second winding wheel 62 can be engaged with the driving gear 5 through the second gear portion 621.

Referring to fig. 5, in some embodiments, a first axle 151 and a second axle 152 are protruded from the stand 15, and the first axle 151 and the second axle 152 are spaced up and down and are parallel to the output shaft of the driving motor 4. The first reel 61 is rotatably connected to a first axle 151 and the second reel 62 is rotatably connected to a second axle 152.

Referring to fig. 5 and 6, in some embodiments, the driving gear 5 drives the first winding wheel 61 and the second winding wheel 62 to rotate in the same direction, and the first winding wheel 61 and the second winding wheel 62 are spaced up and down.

One end of the drive rope 7 is wound around the first reel 61, and the other end is wound around the second reel 62. Meanwhile, both ends of the driving rope 7 are reversely wound around the first winding wheel 61 and the second winding wheel 62, respectively, that is, when one end of the driving rope 7 is clockwise wound around the first winding wheel 61, the other end of the driving rope 7 is counterclockwise wound around the first winding wheel 61. Thus, when one end of the driving rope 7 is wound on the first reel 61 as the first reel 61 rotates, the other end of the driving rope 7 can be unwound on the second reel 62 in synchronization with the rotation of the second reel 62. Similarly, when one end of the driving rope 7 is unreeled on the first reel 61, the other end of the driving rope 7 can be reeled on the second reel 62, and the length of the driving rope 7 between the first reel 61 and the second reel 62 is always kept constant.

It should be noted that, in some embodiments, when the driving gear 5 drives the first winding wheel 61 and the second winding wheel 62 to rotate in opposite directions, the two ends of the driving rope 7 are wound around the first winding wheel 61 and the second winding wheel 62 in the same direction, and the winding and unwinding of the two ends of the driving rope 7 on the first winding wheel 61 and the second winding wheel 62 can also be achieved.

Still referring to fig. 5 and 6, the fixed sheave 8 is provided at a front side of the first and second reels 61 and 62 at an interval for reversing the driving rope 7 and supporting the driving rope 7 such that the driving rope 7 is extended in the front-rear direction. The driving rope 7 is wound out from the first winding wheel 61, is reversed by the fixed pulley 8 and is wound on the second winding wheel 62 again.

The fixed pulley 8 is rotatably connected to the base 1. In some embodiments, a wheel column 111 is protruded from the side wall of the guide plate 11, and the fixed pulley 8 is rotatably sleeved on the wheel column 111.

The drive rope 7 may comprise a first rope portion 71 between the first reel 61 and the fixed pulley 8 and a second rope portion 72 between the second reel 62 and the fixed pulley 8. The first rope portion 71 and the second rope portion 72 are arranged at intervals up and down. It will be appreciated that when the first cord segment 71 is moved towards the front side of the base 1, the second cord segment 72 is moved back and forth relative to the base 1.

The slide block 9 is arranged on the base 1 and is used for transmission connection between the driving rope 7 and the support frame 3. The base 1 is provided with a slide rail 13 extending in the front-rear direction, and the slider 9 is slidably mounted on the slide rail 13. The driving rope 7 can drive the sliding block 9 to slide back and forth on the base 1 along the sliding rail 13, and further drive the support frame 3 and the spray gun 2 to move back and forth along the guide sliding groove 12.

Referring to fig. 5 in combination with fig. 1 to 3, in some embodiments, the first rope portion 71 is fixedly connected to the slider 9, and the slider 9 is provided with a first through hole 91 extending in the front-back direction, and the second rope portion 72 movably penetrates through the first through hole 91. It can be understood that the second rope portion 72 can be fixedly connected to the sliding block 9, and the second rope portion 72 can be movably inserted into the first through hole 91.

When the first rope portion 71 drives the sliding block 9 to move along the sliding rail 13 to the front side of the base 1, the second rope portion 72 can move to the rear side through the first through hole 91. Similarly, when the first rope portion 71 drives the sliding block 9 to move along the sliding rail 13 to the rear side of the base 1, the second rope portion 72 can move to the front side through the first through hole 91.

Referring to fig. 5 in combination with fig. 3, in some embodiments, the slider 9 is provided with a second through hole 92 having an elongated shape. The second perforations 92 are distributed through the slider 9 in a direction perpendicular to the side walls of the guide plate 11. One end of the support frame 3 passes through the second through hole 92 and is slidably connected in the guide chute 12, so that the linkage between the sliding block 9 and the support frame 3 is realized. When the sliding block 9 slides back and forth on the sliding rail 13, the inner wall of the front side or the rear side of the second through hole 92 can abut against the supporting frame 3 to push the supporting frame 3 to move back and forth relative to the base 1.

When the slide block 9 slides forwards along the slide rail 13, the slide block 9 can drive the support frame 3 penetrating through the second through hole 92 to synchronously slide forwards, so that the support frame 3 can drive the spray gun 2 to slide forwards on the base 1 along the guide chute 12.

When the sliding block 9 slides backwards along the sliding rail 13, the sliding block 9 can drive the support frame 3 penetrating through the second through hole 92 to synchronously slide backwards, so that the support frame 3 can drive the spray gun 2 to slide backwards on the base 1 along the guide sliding groove 12.

The length and height of the second through hole 92 on the sliding block 9 correspond to the height of the supporting frame 3. Specifically, as the supporting frame 3 moves on the transverse trough section 121 and the inclined trough section 122, the height of the supporting frame 3 changes, and the second through hole 92 allows the supporting frame 3 to synchronously move up and down on the second through hole 92 so as to correspond to the height of the supporting frame 3 in the guide chute 12.

It should be noted that, the slide block 9 is used for transmission between the driving rope 7 and the support frame 3, and the slide block 9 is matched with the slide of the slide rail 13, so that the forward or backward pulling force of the driving rope 7 on the slide block 9 can be converted into the more stable forward or backward pushing force of the slide block 9 on the support frame 3, and the movement of the support frame 3 is more stable and smooth.

It will be appreciated that in some embodiments, the slider 9 may be omitted, so that the driving rope 7 is directly connected to the supporting frame 3, and the driving rope 7 can also pull the supporting frame 3 to move back and forth relative to the base 1.

Still referring to fig. 7 and 8 in conjunction with fig. 3, the lance 2 is shown as a cylindrical structure. The spray gun 2 is fixed in the support frame 3.

The support frame 3 includes a holster part 31, a first coupling part 32 and a limiting part 33 which are integrally connected.

The gun sleeve part 31 is fixedly sleeved on the spray gun 2. The gun sleeve portion 31 is provided with a through hole 311 for the spray gun 2 to pass through, that is, the gun sleeve portion 31 is fixedly sleeved on the spray gun 2 through the through hole 311.

In some embodiments, screw holes may be correspondingly disposed on the gun case portion 31 and the spray gun 2, so as to fix the gun case portion 31 on the outer peripheral wall of the spray gun 2 by screws, thereby achieving the connection and fixation between the support frame 3 and the spray gun 2.

Referring still to fig. 7 and 8, in some embodiments, a rib 22 is provided on the outer wall of the spray gun 2 and extends axially along the outer wall. The inner wall of the through hole 311 of the holster part 31 is concavely provided with a fixing groove 312 matched with the rib part 22. When the gun case portion 31 is sleeved on the spray gun 2, the rib portion 22 is limited in the fixing groove 312, so that the spray gun 2 can be prevented from rotating in the gun case portion 31, and meanwhile, the quick installation and connection between the spray gun 2 and the support frame 3 are facilitated.

Referring to fig. 7 and 8 in conjunction with fig. 3, the first coupling portion 32 is formed to protrude from one side of the holster portion 31 in a radial direction of the holster portion 31. The first shaft connecting part 32 can pass through the second through hole 92 to be in transmission connection with the sliding block 9, so that the synchronous movement of the support frame 3 and the sliding block 9 is realized.

Referring to fig. 7 to 11 in conjunction with fig. 3, the limiting portion 33 is integrally formed at an end of the shaft connecting portion 32 away from the holster portion 31. The stopper 33 includes a first stopper wall 331 and a second stopper wall 332 provided at an interval in the axial direction of the coupling 32. The first limiting wall 331 is formed at an end of the shaft connecting portion 32 away from the holster portion 31, and the second limiting wall 332 is formed by bending and extending the first limiting wall 331 toward the end away from the holster portion 31.

Referring to fig. 7 to 15, the limiting portion 33 is movably disposed on the top edge of the guide plate 11, and the guide plate 11 is clamped between the first limiting wall 331 and the second limiting wall 332. At this time, the guide chute 12 is provided at the top edge of the guide plate 11, and the first and second stopper walls 331 and 332 can partially cover the guide chute 12.

Still referring to fig. 7 to 15, a first limiting protrusion 34 is convexly disposed on a side wall of the first limiting wall 331 facing away from the gun sleeve portion 31, and the first limiting protrusion 34 extends into the guide chute 12 to slide, so that the movement track of the first coupling portion 32 is guided and limited by the guide chute 12, and the movement of the support frame 3 and the spray gun 2 is more stable.

Two first limit protrusions 34 are provided on the first limit wall 331 and are arranged at intervals in the front-rear direction. The two first limiting protrusions 34 are matched, so that when the support frame 3 is guided, the shaft connecting part 32 can be prevented from rotating relative to the guide chute 12, the support frame 3 can only slide along the guide chute 12, the support frame 3 can be matched with the guide chute 12, and the spray gun 2 is stably supported on the base 1.

Referring to fig. 12 and fig. 9, the side wall of the second limiting wall 332 facing the first limiting wall 331 is convexly provided with second limiting protrusions 35, and the second limiting protrusions 35 are disposed corresponding to the first limiting protrusions 34 one by one. The second limiting protrusion 35 and the first limiting protrusion 34 can respectively extend into the guide sliding groove 12 from two sides of the guide plate 11 to slide, so that the connection between the support frame 3 and the guide sliding groove 12 is more stable.

It is understood that the first position-limiting protrusion 34 may also extend to the second position-limiting protrusion 35 and be integrally connected with the second position-limiting protrusion 35.

It should be noted that, the guide chute 12 is disposed at the top edge of the guide plate 11, so that the limit protrusion on the limit portion 33 can be in sliding connection with the guide chute 12 on the guide plate 11, thereby simplifying the structure of the whole device and reducing the production cost.

The operation trajectory and the movement process of the spray gun 2 in the present embodiment will be specifically described below. In the present embodiment, the spray gun 2 is arranged obliquely downward in the front direction so that the nozzle 21 at the front end of the spray gun 2 can spray toward the upper front direction.

Referring to fig. 9 to 11, when the lance 2 moves forward along with the support frame 3 on the transverse groove section 121 of the guide chute 12, i.e. in the state of fig. 9, the lance 2 and the support frame 3 move forward in a straight line, but the overall inclination angle of the lance 2 is not changed. Therefore, when the driving rope 7 and the slide block 9 push the support frame 3 and the spray gun 2 to move forwards on the transverse groove section 121 of the guide chute 12, the spray gun 2 can translate forwards relative to the base 1, and the vertical dimension H of the spray gun 2 is unchanged while the transverse extending distance of the spray gun 2 is prolonged.

Referring to fig. 12 and 13, when the spray gun 2 moves along with the support frame 3 in the transition area between the transverse groove section 121 and the inclined groove section 122 of the guide chute 12, the spray gun 2 and the support frame 3 can integrally turn along with the movement of the limiting part 33 along the guide chute 12, that is, the spray gun 2 can rotate relative to the base 1, and the vertical dimension H of the spray gun 2 gradually increases along with the rotation of the spray gun 2, and the extension distance of the spray gun 2 in the height direction increases.

Referring to fig. 14 and 15, when the spray gun 2 moves along with the support frame 3 in the inclined chute section 122 of the guide chute 12, the support frame 3 and the spray gun 2 only translate forward and downward relative to the foundation 1, but do not rotate, and the travel track of the spray gun 2 is a straight line inclined forward and downward. And in this process, the vertical dimension H of the lance 2 is not changed, but the projecting distance of the lance 2 in the height direction can be made long. It should be noted that the vertical dimension H of the lance 2 moving with the support 3 on the inclined trough section 122 is greater than the vertical dimension H of the lance moving on the transverse trough section 121.

The spray gun 2 moves on the transverse groove section 121 along with the support frame 3, 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 4 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. 16, 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.

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. 16 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. 16 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 arranged in the toilet lid in an inclined manner, so that the transverse groove section 121 of the guide chute 12 is arranged in an inclined manner. None of the above approaches affect the normal use of the cleaning device 100 in the toilet.
