Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a liquid filling structure for a smart toilet and a smart toilet. Background Technology

[0002] As people's living standards improve, the demand for smart toilet functions is increasing, leading to continuous upgrades in smart toilet functions. Existing smart toilets typically have a foam shield function for odor isolation and a descaling function for purifying pipes. These functions require special liquids to achieve. For example, the foam shield function requires the use of foaming agents to generate foam, and the descaling function requires the use of descaling agents to soften and decompose limescale.

[0003] Typically, the liquid filling port is located on the smart toilet seat, while the liquid storage bottle is hidden inside the ceramic. This requires a flexible liquid guide tube to connect the filling port to the storage bottle. If the installation of the flexible liquid guide tube is difficult during the assembly of the smart toilet, it will have an adverse impact on production efficiency and product reliability.

[0004] like Figure 1 To reduce the installation difficulty of the liquid guiding hose 1', existing smart toilets are equipped with a quick-release structure for the liquid guiding hose 1'. This quick-release structure must include at least the liquid guiding hose 1', a sealing ring 2', a retaining ring 3', a retaining spring 4', a retaining seat 5', a button 6', and a housing 7'. The sealing ring 2', retaining ring 3', retaining spring 4', retaining seat 5', and button 6' are all fitted onto the outside of the liquid guiding hose 1'. Liquid added from the opening of the housing 7' will enter the liquid storage bottle inside the smart toilet through the liquid guiding hose 1'. The smart toilet has a base 8', which is provided with a passage for the liquid guiding hose 1' to pass through. The through hole is provided. The sealing ring 2' is disposed between the housing 7' and the liquid guiding hose 1' to seal and prevent liquid from flowing out from the gap between the housing 7' and the liquid guiding hose 1'. The retaining spring 4' engages with the liquid guiding hose 1'. When the button 6' is pressed upward, the retaining spring 4' is opened by the button 6'. When the button 6' is released, the retaining spring 4' will spring back to its original position. The retaining ring 3' is sleeved in the sealing ring 2' to fix the sealing ring 2' and to limit the upward movement of the retaining spring 4'. The retaining seat 5' is fixed on the housing 7' to fix the retaining ring 3' and to support and limit the retaining spring 4' from falling downward.

[0005] Existing smart toilets feature a quick-release mechanism for the fluid guide hose 1', with a retaining spring 4' forming an inverted buckle on the outer cylindrical surface of the hose 1' to prevent loosening, a sealing ring 2' to prevent leakage, and a button 6' for unlocking. However, this design has the following drawbacks: 1. The numerous and small parts make assembly inconvenient; 2. During installation, it is difficult to confirm that the fluid guide hose 1' is properly installed, and improper installation can easily lead to leakage; 3. The use of a metal retaining spring 4' to form an inverted buckle on the outer cylindrical surface of the hose 1' to prevent loosening can easily damage the outer surface of the hose, potentially causing leakage; 4. When removing the hose 1', it is necessary to press the button 6' while simultaneously pulling it out, which is inconvenient due to the small size of the button 6'.

[0006] In view of the above, the designer of this utility model designed this utility model. Utility Model Content

[0007] The purpose of this utility model is to provide a liquid filling structure for an intelligent toilet and an intelligent toilet in general, which features a simple structure and convenient assembly and disassembly.

[0008] Another objective of this invention is to provide a smart toilet.

[0009] To achieve the above objectives, the present invention adopts the following solution: A liquid filling structure for a smart toilet includes: a liquid filling box assembly, a connecting assembly, and a liquid storage device. The connecting assembly is sealed between the liquid filling box assembly and the liquid storage device. The connecting assembly includes an adapter pipe and a quick-release connector. One end of the adapter pipe is detachably connected to the liquid filling box assembly, and the other end of the adapter pipe is sealed to one end of the quick-release connector via a screw-on structure. The other end of the quick-release connector is sealed to the liquid storage device.

[0010] In some embodiments, the screw-on structure includes protrusions on the outer wall of the quick-release connector and limiting grooves on the side wall of the adapter pipe. The number of protrusions is set to multiple, and the multiple protrusions are spaced apart circumferentially along the quick-release connector. The number of limiting grooves is set to multiple, and the multiple limiting grooves are spaced apart circumferentially along the adapter pipe. The protrusions and limiting grooves correspond one-to-one. The protrusions pass through one side of the limiting groove and are engaged with the other side of the limiting groove to achieve the connection between the quick-release connector and the adapter pipe.

[0011] In some embodiments, an opening is provided on one side of the limiting groove, and the protrusion enters the limiting groove through the opening. The limiting groove includes an integrally formed vertical section and a horizontal section. The opening is integrally formed at the bottom of the vertical section. A recess is formed at the end of the horizontal section away from the vertical section. The protrusion can be inserted into the recess. A limiting protrusion is provided on the lower side of the end where the horizontal section connects to the vertical section. The limiting protrusion makes it difficult for the protrusion to come out of the recess.

[0012] In some embodiments, a liquid filling structure for a smart toilet further includes a quick-release buckle, one end of which is rotatably mounted on the outer wall of the adapter pipe, and the other end of which can engage with the quick-release connector.

[0013] In some embodiments, the quick-release buckle includes an adapter portion, the outer side wall of the adapter tube is provided with two opposing rotating shafts, and the adapter portion is provided with a rotating shaft hole that mates with the rotating shafts.

[0014] In some embodiments, the quick-release buckle seat further includes a spring-loaded buckle portion, which can hold the quick-release connector. The spring-loaded buckle portion is provided with a limiting hole, and the quick-release connector is provided with a limiting rib that cooperates with the limiting hole to form a circumferential limiting rib.

[0015] In some embodiments, one side of the limiting hole forms an anti-rotation edge, and the spring-loaded part is integrally formed with an opening. After the other end of the adapter tube is screwed to one end of the quick-release connector, the spring-loaded part latches the quick-release connector through the opening, and the limiting rib abuts against the anti-rotation edge.

[0016] In some embodiments, the adapter includes an integrally formed first adapter and a second adapter, the first adapter having a liquid inlet end and the second adapter having a liquid outlet end, the liquid filling box assembly having a liquid inlet and a liquid outlet, the liquid inlet end being sealed and inserted into the liquid outlet of the liquid filling box assembly, and the quick-release connector being screwed onto the liquid outlet end.

[0017] In some embodiments, a sealing ring is provided between the quick-release connector and the liquid outlet end, and a liquid outlet check valve is installed inside the head of the quick-release connector.

[0018] A smart toilet includes a toilet body, a toilet seat fixed to the toilet body, and a liquid filling structure for the smart toilet. The liquid filling box assembly is installed on the toilet seat by a snap-on or pull-out method. The adapter pipe is fixed to the liquid filling box assembly by at least one of the following methods: snap-fit, threaded, or adhesive. The liquid storage device is installed on the toilet body or the toilet seat.

[0019] As can be seen from the above technical solution, this utility model, through the structural design of the connecting components, has the following technical effects: Compared to existing smart toilets with quick-release liquid guide hoses that require multiple small, scattered parts such as liquid guide hoses, sealing rings, retaining rings, snap rings, retaining seats, buttons, and housings, this utility model includes core components such as a liquid filling box assembly, a connecting assembly with an adapter and quick-release connector, and a liquid storage device. This directly reduces the number of parts and assembly steps, solving the problem of "many parts and inconvenient assembly" from the source, reducing assembly difficulty during production, improving assembly efficiency on the production line, and facilitating after-sales service. The overall structure is simple.

[0020] The adapter tube of this invention is detachably connected to the liquid filling box assembly at one end, allowing for disassembly and assembly without the need for complex tools. The other end of the adapter tube is sealed to one end of the quick-release connector via a screw-in structure, which enables quick assembly and prevents liquid leakage. The other end of the quick-release connector is sealed to the liquid storage device, further ensuring the overall sealing of the product and simplifying the disassembly process—no buttons need to be pressed; simply release the screw-in structure to disassemble, solving the pain point of "inconvenient disassembly operation" and thus achieving convenient disassembly and assembly.

[0021] This invention replaces the original fluid guiding hose with a metal retaining spring by using a screw-on connection of an adapter and a quick-release connector. This eliminates wear on the outer surface of the hose caused by the metal parts, structurally avoids leakage problems caused by hose damage, and improves product reliability.

Fluid delivery hose Detailed Implementation

[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0034] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0035] Reference Figures 2 to 9 As shown, this utility model discloses a liquid filling structure for a smart toilet, including: a liquid filling box assembly 1, a connecting assembly 2, and a liquid storage device. The connecting assembly 2 is sealed between the liquid filling box assembly 1 and the liquid storage device. The connecting assembly 2 includes an adapter pipe 21 and a quick-release connector 22. One end of the adapter pipe 21 is detachably connected to the liquid filling box assembly 1, and the other end of the adapter pipe 21 is sealed to one end of the quick-release connector 22 via a screw-on structure. The other end of the quick-release connector 22 is sealed to the liquid storage device. The other end of the quick-release connector 22 may be provided with a liquid guiding hose 7, and the outlet end of the liquid guiding hose 7 is sealed to the liquid storage device.

[0036] Therefore, compared to the existing quick-release structure of the liquid guiding hose in smart toilets, which requires multiple scattered small parts such as the liquid guiding hose, sealing ring, retaining ring, snap ring, retaining seat, button, and housing, this utility model includes core components such as a liquid filling box assembly 1, a connecting assembly 2 with an adapter pipe 21 and a quick-release connector 22, and a liquid storage device. This directly reduces the number of parts and assembly steps, solving the problem of "many parts and inconvenient assembly" from the source. This invention addresses several issues, including: First, it reduces assembly difficulty during production, improves assembly efficiency on the production line, and facilitates after-sales service. Second, one end of the adapter tube 21 is detachably connected to the liquid filling box assembly 1, allowing for easy assembly and disassembly without complex tools. The other end of the adapter tube 21 is sealed to one end of the quick-release connector 22 via a screw-on structure. This screw-on structure enables quick assembly, and the sealing design prevents liquid leakage. The other end of the quick-release connector 22 is sealed to the liquid storage device, further ensuring the overall sealing of the product and simplifying the disassembly process—no buttons need to be pressed; simply releasing the screw-on structure allows for disassembly, solving the problem of inconvenient disassembly and achieving convenient assembly and disassembly. Third, the invention replaces the original connection between the liquid guiding hose and the metal retaining spring with a screw-on connection between the adapter tube 21 and the quick-release connector 22, eliminating wear on the hose's outer surface from metal parts and structurally preventing leakage due to hose damage, thus improving product reliability.

[0037] In some embodiments, the screw-on structure includes a protrusion 221 and a limiting groove 211. The protrusion 221 is disposed on the outer side wall of the quick-release connector 22, and the limiting groove 211 is disposed on the side wall of the adapter tube 21. The number of protrusions 221 is set to be multiple, and the multiple protrusions 221 are arranged at intervals along the circumference of the quick-release connector 22. The number of limiting grooves 211 is set to be multiple, and the multiple limiting grooves 211 are arranged at intervals along the circumference of the adapter tube 21. The protrusions 221 and the limiting grooves 211 correspond one-to-one. The protrusion 221 passes through one side of the limiting groove 211 and is engaged with the other side of the limiting groove 211 to realize the connection between the quick-release connector 22 and the adapter tube 21. In the embodiment shown in the figure, the number of protrusions 221 and limiting grooves 211 is two, but it is not limited to this. Thus, the present invention can achieve "precise positioning + quick screw-on" through the cooperation of the protrusions 221 and the limiting grooves 211.

[0038] Please see Figure 5 As shown, an opening 2115 is provided on one side of the limiting groove 211, and the protrusion 221 enters the limiting groove 211 through the opening 2115, which avoids misalignment during assembly and simplifies the connection steps. Initial fixation can be completed without additional tools, solving the problem of "cumbersome assembly" of the original structure.

[0039] Furthermore, the limiting groove 211 may include an integrally formed vertical segment 2111 and a horizontal segment 2112. The opening 2115 is integrally formed at the bottom of the vertical segment 2111. A recessed portion 2113 is formed at the end of the horizontal segment 2112 away from the vertical segment 2111. The protrusion 221 can be inserted into the recessed portion 2113. A limiting protrusion 2114 is provided on the lower side of the end where the horizontal segment 2112 connects to the vertical segment 2111. The limiting protrusion 2114 can prevent the protrusion 221 from easily coming out of the recessed portion 2113. The vertical segment 2111 and the horizontal segment 2112 are connected in a figure-7 shape. The vertical segment 2111 provides a vertical channel for the protrusion 221 to enter. The horizontal segment 2112 guides the protrusion 221 to move horizontally to the recessed portion 2113. The recessed portion 2113 can stably engage the protrusion 221 and prevent it from coming out after connection.

[0040] In addition, the limiting protrusion 2114 on the lower side of the connection between the horizontal segment 2112 and the vertical segment 2111 can prevent the protrusion 221 from falling out of the recess 2113 in the opposite direction, further improving the connection stability and avoiding leakage due to vibration, thus solving the defect of the original structure that "is prone to leakage if not installed properly".

[0041] In some embodiments, the liquid filling structure of the smart toilet of this utility model may further include a quick-release buckle 23, one end of which is rotatably mounted on the outer side wall of the adapter pipe 21, and the other end of which can fasten the quick-release connector 22; thus, this utility model enhances the connection strength between the adapter pipe 21 and the quick-release connector 22 through "secondary fixing", avoiding loosening of the screw connection structure after long-term use, without increasing the complexity of disassembly and assembly, taking into account both stability and convenience, and ensuring a firm and reliable installation.

[0042] Wherein, the diameter of the head 222 of the quick-release connector 22 is larger than the diameter of the bottom 224 of the quick-release connector 22, and the bottom end of the quick-release buckle 23 can be snapped into the bottom surface of the head 222 of the quick-release connector 22.

[0043] In some embodiments, the quick-release buckle 23 may include an adapter 231. The outer wall of the adapter tube 21 is provided with two opposing rotating shafts 212. The adapter 231 is provided with a rotating shaft hole 2311 that cooperates with the rotating shaft 212. The rotating shaft 212 is respectively inserted into the rotating shaft hole 2311, which can realize the flexible rotation of the quick-release buckle 23. The rotational design allows the quick-release buckle 23 to quickly engage or disengage from the quick-release connector 22. The operation is simple and more convenient than the original structure of "pressing a button to unlock".

[0044] Furthermore, the quick-release buckle seat 23 may also include a spring-loaded buckle portion 232, which can hold the quick-release connector 22. The spring-loaded buckle portion 232 is provided with a limiting hole 2321, and the quick-release connector 22 is provided with a limiting rib 223 that cooperates with the limiting hole 2321 to form a circumferential limiting. Thus, by adapting the limiting hole 2321 of the spring-loaded buckle portion 232 to the limiting rib 223 of the quick-release connector 22, a circumferential limiting is formed, preventing the adapter pipe 21 and the quick-release connector 22 from rotating relative to each other, and avoiding sealing failure due to rotational wear at the connection part.

[0045] In some embodiments, one side of the limiting hole 2321 forms an anti-rotation edge 2322, and the spring-loaded part 232 is integrally formed with an opening 2323, which is C-shaped. After the other end of the adapter tube 21 is screwed onto one end of the quick-release connector 22, the spring-loaded part 232 latches onto the quick-release connector 22 through the opening 2323, and the limiting rib 223 abuts against the anti-rotation edge 2322. (See also...) Figure 6 and Figure 7As shown, the quick-release connector 22 can be snapped into the opening 2323 to further restrict circumferential displacement, ensuring the overall structural stability of the product after connection, preventing leakage due to component rotation during liquid flow, and improving sealing reliability. In other words, after the quick-release connector 22 is assembled, it can prevent the quick-release connector 22 from rotating, thereby preventing loosening. The opening 2323 of the spring buckle part 232 can be quickly snapped into the quick-release connector 22, ensuring both tight fastening and simplifying the disassembly steps. The size of the opening 2323 is smaller than the outer diameter of the quick-release connector 22. After installation, the quick-release buckle seat 23 can be clamped on the quick-release connector 22, so that the limiting rib 223 on the quick-release connector 22 and the anti-rotation edge 2322 on the quick-release buckle seat 23 are always in a self-locking state.

[0046] In some embodiments, the spring-loaded part 232 is provided with two opposing limiting steps, and the gap between the two limiting steps forms the opening 2323. After the spring-loaded part 232 latches the quick-release connector 22 through the opening 2323, the limiting step is engaged with the bottom surface of the head 222 of the quick-release connector 22, further limiting the quick-release connector 22 in the longitudinal direction and preventing the quick-release connector 22 from falling off in the event of failure (such as breakage) of the protrusion 221.

[0047] In some embodiments, the adapter pipe 21 includes an integrally formed first adapter pipe 213 and second adapter pipe 214. The first adapter pipe 213 is provided with a liquid inlet end 2131, and the second adapter pipe 214 is provided with a liquid outlet end 2141. The liquid filling box assembly 1 includes a liquid inlet 12 and a liquid outlet 11. The liquid inlet end 2131 is sealed and inserted into the liquid outlet 11 of the liquid filling box assembly 1. The quick-release connector 22 is screwed onto the liquid outlet end 2141. The integrally formed structure reduces splicing gaps and lowers the risk of leakage. At the same time, it clarifies the liquid inlet and outlet paths, making the liquid flow smoother. The first adapter pipe 213 and the second adapter pipe 214 form a 7-shaped connection.

[0048] Furthermore, a sealing ring 3 is provided between the quick-release connector 22 and the liquid outlet 2141, and the adapter pipe 21 and the quick-release connector 22 form a mating fit. The sealing ring 3 enhances the radial sealing of the connection between the two, preventing liquid from seeping out from the gap. The head 222 of the quick-release connector 22 is equipped with a liquid outlet check valve 4, which can prevent the liquid in the liquid storage device from flowing back to the adapter pipe 21, and at the same time prevent external air from entering the liquid storage device and contaminating the liquid, thereby improving the safety of product use and the stability of liquid storage. When liquid is not needed, the liquid outlet channel can be closed by the liquid outlet check valve 4.

[0049] Please see Figure 2As shown, this utility model also discloses a smart toilet, including a toilet body 5, a toilet seat 6 fixed on the toilet body 5, and a liquid filling structure for the smart toilet. The liquid filling box assembly 1 is installed on the toilet seat 6 by a snap-on or pull-out method. The adapter pipe 21 is fixed to the liquid filling box assembly 1 by at least one of the following methods: snap-fit, threaded, or adhesive. The liquid storage device 1 is installed on the toilet body 5 or the toilet seat 6, allowing users to quickly remove the liquid filling box assembly 1 for liquid filling without tools. In the embodiment shown in the figure, the adapter pipe 21 is fixed to the liquid filling box assembly 1 by a snap-fit ​​method, which facilitates quick assembly.

[0050] The liquid filling box assembly 1 can also be locked onto the toilet seat 6 by screws.

[0051] Please see Figure 5 As shown, when installing the liquid filling structure of the smart toilet of this utility model, after the quick-release connector 22 and the liquid outlet end 2141 of the second adapter 214 of the adapter 21 are inserted and rotated, the protrusions 221 respectively enter from the opening 2115 of the limiting groove 211 and are locked into the lower recess 2113 of the limiting groove 211, thus completing the axial mutual fixation; the quick-release buckle 23 then rotates to lock the quick-release connector 22, completing the rotational limitation of the quick-release connector 22 in the circumferential direction, and then the connecting component 2 is installed on the toilet seat 6; conversely, by releasing the quick-release buckle 23 from the quick-release connector 22, the quick-release connector 22 can be removed by rotating it in the opposite direction.
