[0001] The invention relates to the technical field of intelligent toilet accessories, in particular to a water channel cover plate. Background Art

[0002] With the development of social economy and the continuous improvement of people's living standards, people's requirements for living environment are also increasing, especially the demand for personal hygiene is growing. As an important part of modern bathroom facilities, smart toilets are widely welcomed because of their multiple cleaning functions and convenient operation. However, the existing smart toilet cleaners still have some shortcomings in design, especially in the design of the water distribution system.

[0003] The water distribution system of traditional smart toilet cleaners mostly uses an external hose connection, that is, the distribution valve and the spray rod are connected through a hose. Although this design can achieve basic water distribution functions, it also brings a series of problems: Complex structure: External hose connection increases the complexity of the system and makes the overall structure of the cleaner less compact.

[0004] Large space occupied: Due to the need to arrange additional hoses, the overall size of the cleaner is large and the installation space is limited.

[0005] Easy to damage: The hose is exposed to the outside for a long time and is easily affected by environmental factors (such as temperature changes, ultraviolet radiation, etc.), which leads to accelerated aging and increased failure rate.

[0006] Difficult maintenance: The existence of the external hose makes daily maintenance relatively troublesome, especially when cleaning the scale inside the hose.

[0007] Poor aesthetics: The external hose affects the neatness of the appearance of the cleaner, which does not conform to the pursuit of aesthetics in modern homes.

[0008] In view of the above problems, the market urgently needs a new solution that can not only ensure the efficiency and reliability of water distribution, but also simplify the structure, reduce the volume, and improve the user experience. To this end, this application proposes an innovative water channel cover plate design, which fundamentally changes the design concept of the traditional water channel distribution system by integrating the distribution valve with the water channel cover plate. Summary of the invention

[0009] In view of the deficiencies in the background technology, the present invention provides a waterway cover plate.

[0010] The technical solution adopted by the present invention is: a water channel cover plate, including a cover plate main body, a plurality of independent distribution channels are arranged on the bottom end surface of the cover plate main body, a medium inlet is arranged on one end of each of the distribution channels, a distribution valve bottom shell is arranged on the cover plate main body on the back of the medium inlet, a distribution valve main body is connected to the distribution valve bottom shell, and the medium inlet is connected to the valve cavity of the distribution valve main body.

[0011] Furthermore, the distribution valve body includes a distribution valve shell, a driving motor, a water-dividing turntable and a water-dividing plate. The distribution valve shell is connected to the distribution valve bottom shell. The water-dividing plate is arranged in the valve cavity of the distribution valve bottom shell. The output end of the driving motor is connected to the water-dividing turntable. One side of the distribution valve bottom shell has a water inlet.

[0012] Furthermore, the distribution flow channel at least includes a self-cleaning flow channel, a feminine wash flow channel, a buttocks wash flow channel and an external flow channel.

[0013] Furthermore, a self-cleaning butt joint pipe is integrally formed on the back side of the cover plate body at one end of the self-cleaning flow channel away from the medium inlet.

[0014] Furthermore, an external connecting pipe is integrally formed on the back side of the cover plate body at one end of the external flow channel away from the medium inlet.

[0015] Furthermore, it also includes an inlet air flow channel, and an air inlet butt joint pipe is integrally formed on the back side of the cover plate body at one end of the inlet air flow channel away from the medium inlet.

[0016] Furthermore, the water-dividing plate is provided with conducting openings corresponding one-to-one to the medium inlets, and the water-dividing rotating disk is provided with water-dividing openings.

[0017] Furthermore, a fixing column is provided on the cover plate body at the outer periphery of the bottom shell of the distribution valve, and a mounting ear corresponding to the fixing column is provided on the housing of the distribution valve.

This design not only reduces unnecessary external components, but also makes the entire system look more concise and compact.

[0021] 2. Improve integration: The design of the water channel cover adopts a modular concept, organically combining the distribution valve body with the cover body. This highly integrated design not only reduces the overall volume of the cleaner, but also makes installation easier and reduces manufacturing costs.

[0022] 3. Enhanced durability and reliability: By eliminating the external hose, the aging problem of the hose caused by environmental factors (such as temperature changes, UV exposure, etc.) is avoided, thereby improving the durability and reliability of the entire system. At the same time, the internal integrated design also reduces the risk of hose damage due to external interference.

[0023] 4. Easy maintenance and cleaning: The design of the water channel cover makes maintenance and cleaning much simpler. Since all the flow channels are inside the cover body, it is easier to clean and maintain.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] The invention provides a waterway cover plate.

[0036] In this embodiment, refer to Figure 1-5 The water channel cover plate includes a cover plate body 1, and a plurality of independent distribution channels 2 are arranged on the bottom end surface of the cover plate body 1. A medium inlet 3 is arranged on one end of each distribution channel 2. A distribution valve bottom shell 4 is arranged on the cover plate body on the back of the medium inlet 3, and a distribution valve body 5 is connected to the distribution valve bottom shell. The medium inlet is connected to the valve cavity 6 of the distribution valve body.

[0037] In the above technical solution, a plurality of independent distribution channels are processed on the bottom end surface of the cover body, and these channels can be set separately according to different functional requirements. A medium inlet is set at one end of each distribution channel, and the position of the medium inlet corresponds to the corresponding position on the bottom shell of the distribution valve. The bottom shell of the distribution valve is integrally formed on the cover body (of course, it can also be set separately and fixed on the cover body by bolts or other fastening methods), and is connected to the distribution valve body. The valve cavity in the distribution valve body is connected to each distribution channel through the medium inlet, so that the medium flow and cutoff of each medium flow channel are realized through the distribution of the distribution valve.

[0038] After adopting the above solution, the external structure of the washer can be greatly simplified, the complexity and maintenance difficulty caused by the traditional hose connection can be reduced, the system integration can be improved, and the washer can be made more compact and easy to install.

[0039] During specific use, the water channel cover is directly installed to the corresponding position of the outer wall of the washer (such as the installation cavity on the outer wall of the washer). Since the distribution flow channel is closed on three sides and open on one side, after being installed on the outer wall of the washer, a closed flow channel is naturally formed between the distribution flow channel and the outer wall of the washer. Therefore, when the water channel needs to be cleaned, the water channel cover can be directly removed to facilitate cleaning of the inside of the water channel. However, the hose cannot be cleaned or is difficult to clean internally and can only be replaced with a new hose.

[0040] Specifically, the distribution valve body includes a distribution valve shell 7, a driving motor 8, a water-dividing turntable 28 and a water-dividing plate 9. The distribution valve shell is connected to the distribution valve bottom shell. The water-dividing plate 9 is arranged in the valve cavity 6 of the distribution valve bottom shell. The output end of the driving motor is connected to the water-dividing turntable. One side of the distribution valve bottom shell has a water inlet 10.

[0041] The main body of the distribution valve consists of a distribution valve housing, a drive motor, a water distribution disc and a water distribution sheet. The distribution valve housing is tightly connected to the distribution valve bottom shell to ensure sealing. The water distribution sheet is located in the valve cavity of the distribution valve bottom shell. The output shaft of the drive motor is directly connected to the water distribution disc. The water distribution disc is controlled by the drive motor to rotate to achieve accurate water flow distribution. A water inlet is provided on one side of the distribution valve bottom shell for introducing water source. Automatic water flow distribution is achieved through electric control, which improves distribution accuracy and response speed.

[0042] Specifically, the distribution flow channel at least includes a self-cleaning flow channel 11, a feminine wash flow channel 12, a buttocks wash flow channel 13 and an external flow channel 14.

[0043] The distribution channels include but are not limited to self-cleaning channels, women's wash channels, hip wash channels and external channels. They meet the needs of different user groups and provide a more personalized and comfortable cleaning experience. The design of multifunctional channels expands the application range of the cleaner.

[0044] Specifically, a self-cleaning butt joint 15 is integrally formed on the back of the cover plate body at one end of the self-cleaning flow channel away from the medium inlet.

[0045] The far end of the self-cleaning flow channel forms an integrated self-cleaning butt joint on the back of the cover body. This butt joint can be directly connected to the self-cleaning nozzle or other cleaning device inside the cleaner, simplifying the connection method of the self-cleaning system, reducing the number of interfaces and reducing the risk of leakage. At the same time, the integrated design improves the structural strength and stability.

[0046] Specifically, the back of the cover plate body at the end of the external flow channel away from the medium inlet is integrally formed with an external butt joint pipe. The far end of the external flow channel also forms an integrally formed external docking tube on the back of the cover body, which provides a convenient interface for an external water source, allowing the user to connect an additional water source through the washer, thereby enhancing the functionality and flexibility of the washer.

[0047] Specifically, it also includes an inlet air passage 17 , and an inlet butt joint pipe 18 is integrally formed on the back side of the cover plate body at one end of the inlet air passage away from the medium inlet.

[0048] In addition to the distribution channel, an inlet channel is also designed, the far end of which also forms an integrated external butt joint pipe on the back of the cover body. The other end introduces air into the valve cavity through the medium inlet, which is mainly used to introduce air to help generate bubbles or increase the impact of water flow. By introducing air, the cleaning effect can be improved, the water flow can be more delicate and comfortable, and the consumption of water resources may also be reduced.

[0049] Specifically, the water-dividing plate is provided with conducting openings 19 corresponding to the medium inlets one by one, and the water-dividing rotating disk is provided with water-dividing openings 27 .

[0050] There are multiple conduction ports on the water distribution plate, each of which corresponds to a medium inlet. When the water distribution turntable rotates, the water distribution ports on the water distribution turntable are aligned with different conduction ports and medium inlets, thereby achieving selective water supply to different flow channels. This ensures accurate distribution of water flow and avoids the possibility of cross contamination. Complex water flow control logic is achieved through a simple mechanical structure.

[0051] Specifically, a fixing column 20 is provided on the cover plate body at the outer periphery of the bottom shell of the distribution valve, and a mounting ear 21 corresponding to the fixing column 20 is provided on the housing of the distribution valve.

[0052] Several fixing columns are arranged around the bottom shell of the distribution valve, which cooperate with the mounting ears on the distribution valve housing, and the two are firmly fixed together by screws or other fasteners, which improves the convenience and stability of assembly and ensures the stable operation of the distribution valve during operation.

[0053] Specifically, a sealing step 22 extends from the step on the periphery of the distribution channel, and the cross section of the sealing step is a "V"-shaped structure.

[0054] A "V"-shaped sealing step is set on the step outside the distribution channel. This shape helps to form a good sealing interface with the outer wall of the washer. It enhances the sealing performance, prevents water from leaking from the gaps between the distribution channels, and improves the waterproof level of the entire system.

[0055] The present application also provides a cleaning device 23, comprising the above-mentioned water channel cover plate, wherein the outer shell surface of the cleaning device is provided with an installation cavity 24 for installing the water channel cover plate, wherein the installation cavity is provided with a sealing groove 25 adapted to the sealing step, and a transfer through hole 26 is provided in the installation cavity.

[0056] There is a reserved installation cavity on the outer shell of the washer, which is specially used to install the water channel cover. The interior of the installation cavity is designed with a sealing groove that matches the sealing step on the cover to ensure that the cover fits tightly after installation to prevent water penetration. The adapter hole is used to connect with the spray rod of the washer.

[0057] Technical personnel should note that: Although the present invention has been described according to the above specific implementation methods, the concept of the present invention is not limited to this invention, and any modification using the concept of the present invention will be included in the scope of protection of this patent right.
