Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, specifically to a multi-channel valve and a toilet seat with flushing function. Background Technology

[0002] With the improvement of people's living standards and the continuous development of bathroom product technology, multi-functional toilet seats have gradually become an important part of modern home life. These products typically integrate multiple functions such as heating, warm water washing, and sterilization to meet users' higher demands for hygiene and comfort. However, with the diversification of toilet seat functions, the design of their internal water system has become increasingly complex. Traditional valve structures can usually only support a single or limited water flow channel, making it difficult to meet the needs of multiple water outlet mechanisms operating simultaneously or at different times in multi-functional toilet seats. This results in limited water circuit design, affecting the overall performance of the product and the user experience. Furthermore, existing technologies lack valve devices that can flexibly control different water outlets, limiting the implementation of functions such as washing and flushing. Traditional valves cannot provide effective solutions, especially when pre-cleaning the washing mechanism or adjusting different water flow rates are required. Therefore, how to design a valve device that can integrate multi-channel control and achieve precise control of different water outlet mechanisms has become an urgent problem to be solved in the current bathroom product technology field. Utility Model Content

[0003] This utility model provides a multi-channel valve and a toilet seat with flushing function. By optimizing the valve body structure and flow channel design, it solves the shortcomings of the existing technology, such as single water circuit control and limited functional expansion, thereby improving the practicality of the product and the user experience.

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-channel valve, including a valve body, wherein the valve body is provided with a constant flow channel connecting an inlet and a first outlet, and a trigger flow channel connecting the constant flow channel; the trigger flow channel is provided with multiple outlet ends, and the valve body is provided with a valve core assembly for controlling the switching of the outlet ends.

[0005] As a further optimization, the valve body also includes a valve seat, the valve seat having an inner cavity that connects to the water inlet and the first water outlet respectively, the valve core assembly passing through the inner cavity, and a gap being left between the inner wall of the inner cavity and the valve core assembly.

[0006] As a further optimization, the valve core assembly includes a control handle, a moving ceramic plate, and a stationary ceramic plate. The stationary ceramic plate is coaxially fixed inside the valve seat, and the moving ceramic plate rotates and fits tightly against the upper end of the stationary ceramic plate. The control handle is coaxially mounted on the upper end of the moving ceramic plate. The moving ceramic plate has a through hole, and the upper end of the through hole communicates with the inner cavity. The stationary ceramic plate has connection holes for connecting to the water outlets of each of the trigger flow channels.

[0007] As a further optimization, the valve body is also provided with a second outlet, a third outlet and a fourth outlet, and the static ceramic plate is provided with a first connecting hole for connecting the second outlet, a second connecting hole for connecting the third outlet, and a third connecting hole and a fourth connecting hole for connecting the fourth outlet.

[0008] As a further optimization, the third and fourth connecting holes are arranged at intervals between the first and second connecting holes.

[0009] As a further optimization, the diameters of the first and second connecting holes gradually increase from one end closer to the fourth outlet to the other.

[0010] As a further optimization, the valve core assembly also includes a sealing seat disposed between the valve seat and the stationary ceramic plate; the sealing seat has multiple openings.

[0011] As a further optimization, a knob is provided at the upper end of the control handle.

[0012] This utility model also provides a toilet seat with a flushing function, including a cover plate, a seat plate, and a multi-pass valve disposed on the seat plate as described in any of the above.

[0013] As a further optimization, the seat plate is equipped with a water inlet connector, a switch valve, a flushing mechanism, and a cleaning mechanism. The water inlet connector is used to connect to the water inlet; the first water outlet is used to connect to the water inlet of the switch valve; the water inlet of the flushing mechanism is connected to the second water outlet and the third water outlet respectively; the water inlet of the cleaning mechanism is connected to the fourth water outlet, and the cleaning mechanism is used to clean the flushing mechanism.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0015] First, it achieves multiple water outlet functions through a single inlet, meeting the needs of multi-functional toilet seats. Specifically, the constant flow channel guides water flow to an external switch valve, and the combination of independent control and triggering of the flow channel allows water flow to be distributed to multiple outlets through a single inlet, better adapting to the independent use of different functions and significantly simplifying the complexity of the water system.

[0016] Secondly, the relative rotation of the moving and stationary ceramic discs allows for precise control of the switching on and off of different water outlets. The design of the fit between the through-hole of the moving ceramic disc and the connection hole of the stationary ceramic disc ensures the accuracy and stability of water flow switching.

[0017] Third, the sealing seat ensures isolation between each outlet, preventing water flow misalignment and overflow. This effectively ensures the valve body's sealing performance and functional accuracy.

[0018] Fourth, manual adjustment is achieved through knobs and control handles, making it convenient for users. The anti-slip texture of the knobs and the design of limiting the rotation angle range enhance the ease of operation and safety.

[0019] Fifth, water is supplied to the cleaning mechanism first during use to ensure that the rinsing mechanism is clean before use. The priority connection design of the fourth water outlet allows the cleaning mechanism to remove dirt from the rinsing mechanism in a timely manner, improving the level of hygiene.

[0020] In summary, this utility model provides a multi-channel valve with a compact structure, diverse functions, and convenient operation, as well as a toilet seat with a flushing function, significantly improving user experience and product practicality. By optimizing the valve body structure and flow channel design, it solves the problems of low water control efficiency and complex structure in existing technologies, and has high market application value and promising prospects for technology promotion.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Depend on Figures 1 to 4 As shown, this utility model relates to a multi-channel valve and a toilet seat with a flushing function. Its core lies in optimizing the structure of the valve body 1 and the flow channel design to achieve multi-functional water circuit control and ensure convenient operation and sealing performance.

[0029] Preferably, the overall structure of the valve body 1 includes an inlet 8, a first outlet 9, a second outlet 10, a third outlet 11, and a fourth outlet 12. The valve body 1 contains a constant flow channel 13 and a trigger flow channel 14. The constant flow channel 13 connects the inlet 8 and the first outlet 9, and is used to guide the water flow to an external switching valve 5 for independent control. The trigger flow channel 14 has multiple outlet ends, respectively connected to the second outlet 10, the third outlet 11, and the fourth outlet 12. This flow channel design allows a single inlet 8 to meet multiple water outlet function requirements, simplifying the complexity of the water system.

[0030] Preferably, the valve body 1 further includes an upper valve seat 15 and a lower valve seat 16. The upper valve seat 15 is vertically continuous and fitted inside the lower valve seat 16, forming an integral valve seat structure. The upper valve seat 15 has an inner cavity 17, with openings 18 on both sides to connect the inlet 8 and the first outlet 9, while also providing installation space for the valve core assembly. A gap is left between the inner wall of the inner cavity 17 near the valve seat and the valve core assembly, forming a constant flow channel 13 to ensure smooth water flow. Multiple sealing rings are provided between the upper part of the valve core assembly and the upper valve seat 15 to seal the top of the inner cavity 17; details are omitted here.

[0031] Preferably, the valve core assembly consists of a control handle 19, a moving ceramic plate 20, a stationary ceramic plate 21, and a sealing seat 22. The stationary ceramic plate 21 is installed and fixed in the lower valve seat 16 by a pin engagement. The moving ceramic plate 20 is coaxially disposed at the lower end of the control handle 19 by a snap engagement, while the moving ceramic plate 20 is in close contact with the upper end of the stationary ceramic plate 21. When the control handle 19 is rotated, it can drive the moving ceramic plate 20 to rotate, thereby realizing the water outlet control of different outlets. The moving ceramic plate 20 is provided with a through hole 23, the upper end of which communicates with the inner cavity 17 to connect to the constant flow channel 13. The stationary ceramic plate 21 is constructed with multiple connection holes, including a first connection hole 24 for connecting to the second outlet 10, a second connection hole 25 for connecting to the third outlet 11, and a third connection hole 26 and a fourth connection hole 27 for connecting to the fourth outlet 12. The third connecting hole 26 and the fourth connecting hole 27 are spaced apart and located between the first connecting hole 24 and the second connecting hole 25. It should be noted that all connecting holes are on the same circumference to ensure that the through hole 23 can connect accordingly when it rotates; this will not be elaborated further. In the normally closed state, the through hole 23 is located between the third connecting hole 26 and the fourth connecting hole 27, and is in a closed state. When the moving ceramic disc 20 rotates, the through hole 23 passes sequentially through the third connecting hole 26 or the fourth connecting hole 27, and the first connecting hole 24 or the second connecting hole 25, achieving precise control of different water outlets.

[0032] Furthermore, the diameters of the first connecting hole 24 and the second connecting hole 25 gradually increase from one end near the fourth outlet 12 to the other. This design adjusts the cross-sectional size of the water flow, thereby regulating the water flow intensity. Specifically, when the moving ceramic disc 20 rotates to connect the through hole 23 to the first connecting hole 24 or the second connecting hole 25, the water flows separately through the second outlet 10 or the third outlet 11 into the rinsing mechanism 6, corresponding to two independent rinsing nozzles. The water outlet directions of the two nozzles form an angle with the horizontal plane, and a multi-hole diversion structure is provided at the nozzle outlet, which allows the water flow to be evenly distributed on different parts of the user's buttocks, providing a comfortable and efficient rinsing experience.

[0033] Furthermore, the sealing seat 22 is disposed between the lower valve seat 16 and the stationary ceramic plate 21 by means of snap-fit ​​or pin, to isolate the water flow channels between the outlets and prevent misaligned water discharge. The sealing seat 22 has multiple openings, each corresponding to and connecting to the connecting holes on the stationary ceramic plate 21 and the outlets at the bottom of the valve seat. The sealing seat 22 also has sealing grooves for installing irregularly shaped sealing rings, which will not be elaborated upon here. In practical applications, the design of the sealing seat 22 significantly improves the sealing effect of the valve body 1, reducing the risk of leakage and misaligned water discharge.

[0034] Preferably, the upper end of the control handle 19 is connected to a knob 28, the surface of which is provided with anti-slip texture for easy user operation. The rotation angle range of the knob 28 is limited to 10 degrees, corresponding to the relative position change of the through hole 23 of the moving ceramic plate 20 and the connection hole of the stationary ceramic plate 21. With each degree of rotation, the through hole 23 sequentially connects to the fourth water outlet 12, the second water outlet 10, or the third water outlet 11, realizing precise control of the cleaning mechanism 7 and the rinsing mechanism 6. For example, when the knob 28 is rotated to the left or right from the initial position, the through hole 23 connects to the third connection hole 26 or the fourth connection hole 27, and the water flow preferentially flows to the fourth water outlet 12, so that the cleaning mechanism 7 first cleans the rinsing mechanism 6 to ensure the cleanliness of the rinsing mechanism 6. Subsequently, the knob 28 is rotated in the same direction, and the through hole 23 connects to the first connection hole 24 or the second connection hole 25, and the water flow flows to the second water outlet 10 or the third water outlet 11 respectively, activating the rinsing mechanism 6 to perform buttock rinsing.

[0035] This utility model also relates to a toilet seat with a flushing function, including a cover plate 2, a seat plate 3, and a multi-way valve head disposed on the seat plate 3. The seat plate 3 has a built-in water inlet connector 4, a switching valve 5, a flushing mechanism 6, and a cleaning mechanism 7. The specific structures of the water inlet connector 4, the switching valve 5, the flushing mechanism 6, and the cleaning mechanism 7 are not described in detail here. The water inlet connector 4 is used to connect to the water inlet 8, introducing external water into the valve body 1. The first water outlet 9 is connected to the water inlet of the switching valve 5, enabling independent control of the water flow. The water inlet of the flushing mechanism 6 is connected to the second water outlet 10 and the third water outlet 11, respectively, for flushing different parts of the user's buttocks. The water inlet of the cleaning mechanism 7 is connected to the fourth water outlet 12, for cleaning the flushing mechanism 6 before each use, removing residues in the flushing mechanism 6 through water flow impact, preventing bacterial growth and ensuring hygiene. The cleaning mechanism 7 and the flushing mechanism 6 are connected to the water outlet of the touch-sensitive flow channel of the multi-way valve body 1 via hoses, and are controlled by the user.

[0036] In practical applications, users activate the touch-sensitive flow channel of the multi-channel valve by rotating knob 28. First, rotating knob 28 from the initial position connects through-hole 23 to either the third connection hole 26 or the fourth connection hole 27, allowing water to flow preferentially to the fourth outlet 12. The cleaning mechanism 7 receives the water flow and cleans the flushing mechanism 6. Subsequently, the user continues to rotate knob 28, connecting through-hole 23 to either the first connection hole 24 or the second connection hole 25. Water then flows to either the second outlet 10 or the third outlet 11, activating the flushing mechanism 6 for posterior rinsing. The two nozzles of the flushing mechanism 6 are designed according to water flow intensity and direction to ensure a uniform and comfortable rinsing effect. Throughout the process, the sealing seat 22 effectively isolates the water flow channels between the outlets, preventing cross-contamination that could affect the rinsing effect, such as when rinsing the posterior, ensuring accuracy and safety in use.

[0037] This invention optimizes the structure and flow channel design of the valve body 1, enabling a single inlet 8 to meet the needs of multiple water outlet functions, significantly simplifying the complexity of the water system. The relative rotation design of the moving ceramic disc 20 and the stationary ceramic disc 21 ensures the accuracy and stability of water flow switching. The irregularly shaped sealing design of the sealing seat 22 enhances sealing performance, extends service life, and ensures functional precision. The anti-slip texture of the knob 28 improves ease of operation. The design that prioritizes water supply to the cleaning mechanism 7 ensures that the flushing mechanism 6 is clean before use, improving hygiene.

[0038] In summary, this utility model provides a multi-channel valve with a compact structure, diverse functions, and convenient operation, as well as a toilet seat with a flushing function. It solves the problems of low water control efficiency and complex structure in the prior art, and has high market application value and promising prospects for technology promotion.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
