Referring to fig. 2, when the spray gun 2 moves forward relative to the guide plate 1, it is in an extended state at least partially exposed out of the toilet lid, so as to clean the human body.

Still referring to fig. 1 to 3, the supporting frame 3 is movably disposed on the guiding plate 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 guide plate 1 so as to extend out or retract into the toilet lid.

Referring to fig. 3 and 4, in some embodiments, the spray gun 2 is vertically disposed at one side thereof. The guide plate 1 extends in the front-rear direction and is distributed on one side of the support frame 3.

The guide plate 1 is provided with a guide chute 12 extending in the front-rear direction. One end of the support frame 3 can stretch into the guide chute 12 to slide, namely, the support frame 3 can slide back and forth along the extending direction of the guide chute 12, so that the support frame 3 and the spray gun 2 can be guided by the guide chute 12, and the movement track of the support frame 3 and the spray gun 2 is limited.

The height of the guide chute 12 on the guide plate 1 corresponds to the height of the support frame 3 and the spray gun 2 on the guide plate 1. In some embodiments, the guide chute 12 is disposed at the top edge of the guide plate 1 to reduce the height dimension of the guide plate 1, thereby reducing the material required for manufacturing the guide plate 1 and achieving the overall cost reduction.

Referring to fig. 3 and 4, in the present embodiment, the guide chute 12 is an arc-shaped chute structure. 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 frame 3 gradually decreases as the support frame 3 moves from back to front on the curved guide runner 12.

Referring to fig. 5 in conjunction with fig. 3, in some embodiments, the guide chute 12 may also be a segmented structure, and 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.

It should be noted that the height of the supporting frame 3 is not changed or changes slowly when the supporting frame 3 moves on the transverse trough section 121. When the support shelf 3 is moved over the inclined trough section 122, the height of the support shelf 3 changes relatively faster than when it is moved over the transverse trough section 121.

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 guide plate 1.

Referring to fig. 6 in conjunction with fig. 3, the driving assembly includes a driving motor 4 and a swing link 5. Wherein, the driving motor 4 is arranged on the guide plate 1 and is 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. One end of the swing rod 5 is fixed on the output shaft of the driving motor 4, that is, the swing rod 5 is connected with the output end of the driving motor 4 and can synchronously rotate along with the rotation of the output shaft of the driving motor 4.

In some embodiments, the output shaft of the drive motor 4 is perpendicular to the plane of the guide plate 1. The swing rods 5 are distributed along the radial extension of the output shaft of the driving motor 4, so that the swing plane of the swing rods 5 is parallel to the plane of the guide plate 1.

In some embodiments, the swing link 5 is provided with a through hole 51, and the through hole 51 penetrates through the swing link 5 in a direction perpendicular to the plane of the guide plate 1. The through hole 51 is elongated and extends in the radial direction of the output shaft of the drive motor 4. The supporting frame 3 is movably inserted into the through hole 51, and then the swing rod 5 and the supporting frame 3 are linked. The support frame 3 is movable in the radial direction of the output shaft of the drive motor 4 at the through hole 51. When the swing rod 5 rotates synchronously with the output shaft of the driving motor 4, the side wall of the through hole 51 can abut against the support frame 3 and push the support frame 3 to move back and forth relative to the guide plate 1.

When the swing rod 5 rotates relative to the front side of the guide plate 1, the swing rod 5 can drive the support frame 3 penetrating through the through hole 51 to synchronously slide forward relative to the guide plate 1, and further drive the spray gun 2 to extend out of the guide plate 1 forward.

When the swing rod 5 rotates relative to the rear side of the guide plate 1, the swing rod 5 can drive the support frame 3 penetrating through the through hole 51 to synchronously slide backwards relative to the guide plate 1, and further drive the spray gun 2 to retract backwards into the guide plate 1.

Referring to fig. 7 in conjunction with fig. 3, the lance 2 is a cylindrical structure. The spray gun 2 is fixed in the support frame 3.

The support frame 3 includes a holster part 31, a shaft connecting 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 has a fixing 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 fixing 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.

Still referring to fig. 7, 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 fixing hole 311 of the holster part 31 is concavely provided with a positioning 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 positioning 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.

Still referring to fig. 7 in conjunction with fig. 3, the shaft connecting portion 32 is formed on one side of the holster portion 31 in a protruding manner along the radial direction of the holster portion 31. The shaft connecting part 32 can pass through the through hole 51 to be in transmission connection with the swing rod 5, so that synchronous rotation movement of the support frame 3 and the swing rod 5 is realized.

Referring to fig. 7 to 10 in combination 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 in conjunction with fig. 1 to 3, the limiting portion 33 is movably disposed at the top edge of the guide plate 1, and the guide plate 1 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 1, and the first and second stopper walls 331 and 332 can partially cover the guide chute 12.

Still referring to fig. 7 to 10, a first limiting protrusion 34 is protruded from 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 guiding chute 12 to slide, so that the movement track of the first coupling portion 32 is guided and limited by the guiding 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 guide plate 1.

Referring to fig. 9 and fig. 7, 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 1 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 1, so that the limit protrusion on the limit portion 33 can be in sliding connection with the guide chute 12 on the guide plate 1, 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. 8 and 11, when the spray gun 2 moves forward along with the support frame 3 on the arc-shaped guide chute 12, i.e. in the process from the state of fig. 8 to the state of fig. 11, the rear end of the spray gun 2 and the support frame 3 move forward in an arc-shaped manner, and the front end of the spray gun 2 moves downward synchronously while sliding forward relative to the guide plate 1, so that the whole spray gun 2 can rotate along with the support frame 3 relative to the guide plate 1, and the forward extension and the gradual steering of the spray gun 2 are realized.

Therefore, when the spray gun 2 moves forwards on the arc-shaped guide chute 12, the spray gun 2 can slide and rotate relative to the guide plate 1, 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 extending distance of the spray gun 2 in the height direction can be prolonged. And then when making spray gun 2 shrink in the toilet lid, its occupation space in the direction of height of toilet lid inside can reduce, still can guarantee that its protrusion distance under the state of stretching out is longer, has realized carrying out the scheme that long distance stretches out and draws back in the low space, and then is favorable to realizing the frivolousization and the miniaturization of closestool to effectively guarantee spray gun 2's protrusion distance.

It can be understood that, when the guide chute 12 adopts a sectional structure of the transverse groove section 121 and the inclined groove section 122, 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, so that the spray gun 2 can slide and rotate relative to the guide plate 1, the transverse extension distance of the spray gun 2 is increased, and the vertical dimension H of the spray gun 2 is gradually increased along with the rotation of the spray gun 2, so that the extension distance in the height direction can be increased.

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. 12, 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. 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 washing device 100, the guide plate 1 may be horizontally disposed inside the toilet lid 200, or the guide plate 1 may be obliquely disposed inside the toilet lid. 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 invention at least has the following advantages and positive effects:

in the cleaning device 100 for the toilet bowl, provided by the embodiment of the invention, the forward and reverse rotation of the driving motor 4 is matched with the swing rod 5, so that the swing rod 5 can swing back and forth, and further the support frame 3 and the spray gun 2 are provided with power capable of stretching back and forth, and the support frame 3 and the spray gun 2 can be driven to slide back and forth on the guide plate 1 along the guide chute 12, and further the spray gun 2 can extend out of the guide plate 1 or shrink back into the guide plate 1; meanwhile, the support frame 3 is used for supporting the spray gun 2, so that the support frame 3 can drive the spray gun 2 to stretch back and forth relative to the guide plate 1, the structure of the cleaning device 100 is optimized and simplified, the occupation of the spray gun 2 and the cleaning device 100 in the space of the closestool is reduced, and the product is light and thin.
