Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a cleaning device and a toilet with the cleaning device. Background Technology

[0002] With the widespread adoption of smart toilets, people have increasingly diverse requirements for their appearance, and slim toilet seat assemblies are gaining popularity. Existing smart toilet seat assemblies typically have a washing device on the base for ergonomic purposes. This device usually includes a support frame, a moving tube, a washing pipe (i.e., a flexible hose), a drive mechanism, and a water flow switching valve. The drive mechanism moves the moving tube back and forth relative to the support frame, and the washing pipe connects the water flow switching valve and the moving tube. For integrated washing devices that combine the support frame, moving tube, washing pipe, drive mechanism, and water flow switching valve, current technology requires sufficient space above the support frame for the washing pipe to move. This increases the required height of the seat assembly, limiting its overall height and failing to meet consumer expectations for slim smart toilets, becoming a pain point for both the industry and consumers.

[0003] In view of this, how to provide a cleaning device that can reduce the height space occupied by the cleaning pipeline, thereby making the toilet seat assembly lighter and thinner, is a technical problem to be solved in this field. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a toilet cleaning device with a simple structure that can effectively reduce the height space occupied, thereby making the toilet seat assembly lighter and thinner.

[0005] The technical solution adopted in this utility model is:

[0006] A toilet cleaning device, comprising:

[0007] A bracket is fixed to the base of the toilet seat assembly, and the bracket has a hose groove inside.

[0008] A movable tube is mounted on the support and can extend and retract back and forth. The front end of the movable tube is provided with several spray holes.

[0009] A switching valve is fixed on the bracket. The switching valve has an inlet and several outlets. The switching valve can switch between connecting the inlet and each outlet.

[0010] Several hoses, each hose having its inlet end connected to the corresponding outlet on the switching valve, and each hose having its outlet end connected to the corresponding nozzle on the moving pipe;

[0011] As the movable tube retracts relative to the bracket, the flexible tube gradually enters the flexible tube groove; as the movable tube extends relative to the bracket, the flexible tube gradually leaves the flexible tube groove.

[0012] In a preferred embodiment, there are two or more hoses, and each hose is arranged horizontally side by side.

[0013] In a preferred embodiment, the hose groove is located at the rear of the bracket, with the top and front ends of the hose groove being open, and the bottom wall of the hose groove being concave and connected to the rear wall of the hose groove.

[0014] In a preferred embodiment, the switching valve is mounted on the bracket at a position in front of the hose groove.

[0015] In a preferred embodiment, both the inlet and outlet of the switching valve are positioned facing the rear end of the bracket.

[0016] In a preferred embodiment, the rear end of the movable tube is engaged with the flexible tube for limiting.

[0017] In a preferred embodiment, the movable tube is provided with a plurality of axially extending fluid channels, each of the hoses is connected to the corresponding nozzle through the corresponding fluid channel, the water inlet end of the fluid channel extends to the rear end of the movable tube, and the water outlet end of each hose is inserted and fixedly connected to the water inlet end of each fluid channel.

[0018] In a preferred embodiment, the top of the support is provided with guide rails on the left and right sides respectively, which guide and cooperate with the moving tube. A tube cavity is formed between the two guide rails. The flexible tube passes through the tube cavity. When the moving tube extends or retracts relative to the support, the flexible tube moves in the tube cavity. The groove of the flexible tube is located below the tube cavity and is connected to the tube cavity.

[0019] In a preferred embodiment, the device further includes a drive motor and a transmission component mounted on the bracket, wherein the drive motor drives the movable tube to move back and forth relative to the bracket via the transmission component.

[0020] In addition, this utility model also provides a toilet, including a toilet seat with a urinal and a toilet seat assembly disposed on the toilet seat. The toilet seat assembly is provided with a base and also includes a cleaning device as described in any of the above.

[0021] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0022] This utility model discloses a toilet cleaning device that, by incorporating a hose groove within the support frame, allows the hose to gradually enter the groove as the moving tube retracts relative to the support frame. This effectively conceals most of the hose within the support frame, reducing the length of the hose protruding from the frame when the moving tube is retracted. Consequently, it eliminates the need for sufficient space above the support frame for hose movement, as required in existing technologies, thus saving significant height space. Furthermore, existing technologies, lacking effective hose concealment, may result in excessive bending of the hose, hindering its protection and flexibility. This utility model, by using a hose groove to conceal the hose, effectively prevents excessive bending, thus promoting hose protection and flexible movement. Attached Figure Description

[0039] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0040] Please see Figures 1-7 As shown, a preferred embodiment of the toilet cleaning device of this utility model includes a bracket 10, a moving tube 20, a switching valve 30, and several flexible hoses 40, etc., wherein:

[0041] The bracket 10 is fixed to the base (not shown) of the toilet seat assembly, and the bracket 10 has a hose groove 11 inside;

[0042] The movable tube 20 is mounted on the support 10 in a telescopic manner, and the front end of the movable tube 20 is provided with several spray holes 21.

[0043] The switching valve 30 is fixed on the bracket 10. The switching valve 30 is provided with an inlet 31 and several outlets 32. The switching valve 30 can switch between controlling the connection between the inlet 31 and each outlet 32.

[0044] Several hoses 40, the inlet end of each hose 40 is connected to the corresponding outlet 32 ​​on the switching valve 30, and the outlet end of each hose 40 is connected to the corresponding nozzle 21 on the moving pipe 20. The switching valve 30 switches the water supply to each nozzle 21 through each hose 40.

[0045] As the moving tube 20 retracts relative to the support 10, the hose 40 gradually enters the hose groove 11. As the moving tube 20 extends relative to the support 10, the hose 40 gradually leaves the hose groove 11.

[0046] By providing a hose groove 11 within the support 10, the hose 40 can gradually enter the hose groove 11 as the moving tube 20 retracts relative to the support 10. This allows most of the hose 40 to be housed within the support 10 itself, reducing the length of the hose 40 protruding from the support 10 when the moving tube 20 is retracted. Consequently, it eliminates the need for sufficient space above the support for the hose to move freely, as required in existing technologies, effectively saving the height space occupied by the entire cleaning device. Furthermore, existing technologies, lacking effective hose storage, may result in excessive bending of the hose, hindering its protection and flexibility. This invention, by providing a hose groove to house the hose, effectively prevents excessive bending, thus promoting hose protection and flexible movement.

[0047] Specifically, in this embodiment, there are two or more hoses 40, and each hose 40 is arranged horizontally side by side. This arrangement of the hoses 40 horizontally side by side can further reduce the height space occupied by the hoses 40.

[0048] Specifically, in this embodiment, the hose groove 11 is located at the rear of the bracket 10. The top end 111 and the front end 112 of the hose groove 11 are open. The bottom wall 113 of the hose groove 11 is concave and connected to the rear wall 114 of the hose groove 11. With this design, during the process of the moving tube 20 retracting relative to the bracket 10, the hose 40 gradually enters the hose groove 11 from front to back and from top to bottom, making the storage process smoother and enabling the hose 40 to move very flexibly and freely.

[0049] In this embodiment, the switching valve 30 is installed on the bracket 10 in front of the hose groove 11, which is a more reasonable design layout. Furthermore, the inlet 31 and outlet 32 ​​of the switching valve 30 are both set towards the rear end of the bracket 10, so that the inlet and outlet ends of the hose 40 are facing forward, which is more conducive to the flexible back-and-forth movement of the hose 40.

[0050] In this embodiment, the rear end of the movable tube 20 is engaged with the flexible hose 40. The engagement between the two ensures that the length of the flexible hose 40 exposed outside the movable tube 20 remains consistent, which further facilitates the flexible movement of the flexible hose 40 back and forth.

[0051] Specifically, the moving tube 20 has several axially extending fluid channels (not shown), and each hose 40 is connected to the corresponding nozzle 21 through the corresponding fluid channel. The water inlet end of the fluid channel extends to the rear end of the moving tube 20, and the water outlet end of each hose 40 is inserted and fixed to the water inlet end of each fluid channel, thereby achieving a limiting fit between the rear end of the moving tube 20 and the hose 40. The structure is simple and easy to assemble.

[0052] In this embodiment, the top left and right sides of the bracket 10 are respectively provided with guide rails 12 that guide and cooperate with the moving tube 20. A slider 22 is provided on the bottom surface of the rear end of the moving tube 20. The slider 22 is provided with a sliding groove 221. The guide rail 12 is a rib extending along the moving direction of the moving tube 20. The rib slides and cooperates with the sliding groove 221 on the slider 22, thereby realizing the sliding guidance of the moving tube 20.

[0053] A tube cavity 13 is formed between the two guide rails 12. The flexible hose 40 passes through the tube cavity 13. When the moving tube 20 extends or retracts relative to the support 10, the flexible hose 40 moves in the tube cavity 13. The flexible hose groove 11 is located below the tube cavity 13 and is connected to the tube cavity 13.

[0054] In this embodiment, a drive motor 50 and a transmission component 60 are also included, both mounted on the bracket 10. The drive motor 50 drives the moving tube 20 to move back and forth relative to the bracket 10 via the transmission component 60. The drive motor 50 and the transmission component 60 can employ existing known structures. Specifically, in this embodiment, the transmission component 60 includes a transmission wheel and a steel belt. The transmission wheel and the drive motor 50 are linked and cooperate. One end of the steel belt is connected to the transmission wheel, and the other end is connected to the moving tube 20. The steel belt can be wound around the transmission wheel 61.

[0055] In addition, this utility model also provides a toilet, including a toilet seat (not shown) with a urinal and a toilet seat assembly (not shown) disposed on the toilet seat. The toilet seat assembly is provided with a base, and the toilet also includes a cleaning device as described above.
