Description

Technical Field

[0001] This utility model generally relates to the field of bathroom equipment technology, and more specifically, to a multi-water nozzle and its intelligent toilet. Background Technology

[0002] In the field of smart toilets, the practicality and comfort of the cleaning function directly affect the user experience, and the diversity of water patterns is one of the core influencing factors. Currently, the nozzle water outlet structure of mainstream smart toilet cleaning systems on the market generally has functional limitations: on the one hand, most products can only provide a single water pattern (such as conventional direct jet), which is difficult to meet the differentiated needs of different users (such as adults and children) or different usage scenarios (such as daily cleaning and precise flushing); on the other hand, even if some products attempt to achieve multi-water pattern switching, they mostly rely on setting multiple independent water outlets to output different water flows.

[0003] Under the current technological state, when users need to switch washing modes, they either face the dilemma of having no suitable water type to choose from, or they have to move the entire nozzle to switch between different water outlets. This is not only cumbersome, but the washing effect may also be affected by the misalignment of the water outlet position. In addition, the design of multiple water outlets increases the complexity of the nozzle structure, installation space, and manufacturing and maintenance costs, which is not conducive to the miniaturization and lightweight development of smart toilets. Therefore, developing a technical solution that can switch between multiple washing water types from a single water outlet is the key to solving the current dilemma.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The present invention includes a series of simplified concepts, which will be further explained in detail in the detailed description section. This present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] One of the main objectives of this utility model is to overcome at least one of the defects of the prior art and to provide a multi-water nozzle and its intelligent toilet.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: According to one aspect of the present invention, a multi-water nozzle is provided, comprising: a body having a first flow channel, a second flow channel, a first water passage cavity, a second water passage cavity, a first nozzle, and a second nozzle; the first nozzle and the second nozzle are coaxially arranged, the first flow channel, the first water passage cavity, and the first nozzle are sequentially connected to form a first water path, and water sprayed from the first nozzle is sprayed out through the second nozzle; the second flow channel, the second water passage cavity, and the second nozzle are sequentially connected to form a second water path; and a control valve for controlling the on / off state of the first water path and / or the second water path; the first water passage cavity or the second water passage cavity is used to convert the water flow state into a direct flow or a spiral flow.

[0008] According to one embodiment of the present invention, the first water passage cavity further includes a rectification structure; the rectification structure is a tubular structure with a certain length, and the tubular structure is a straight pipe and / or a tapered pipe.

[0009] According to one embodiment of the present invention, the second water passage cavity is formed by a boss and a main cavity wall, and at least one water inlet groove is provided between the boss and the main cavity wall, the water inlet groove being connected to the second flow channel and the second water passage cavity.

[0010] According to one embodiment of the present invention, the water inlet tank includes a first water inlet tank that enters the second water passage chamber along an inclined direction and a second water inlet tank that enters the second water passage chamber along an inclined direction, and the water in the first water inlet tank and the second water inlet tank flows in the same direction after entering the second water passage chamber.

[0011] According to one embodiment of the present invention, the second water passage cavity is provided with a spiral cavity, the spiral cavity is connected to the water inlet groove, and the protrusion is recessed inward and surrounds the main cavity wall to form a spiral cavity.

[0012] According to one embodiment of the present invention, the main body includes an upper cover, a front cover, and a lower cover. The upper cover and the front cover are welded together to form a first water passage cavity, and the lower cover and the front cover are welded together to form a second water passage cavity. The boss, the main cavity wall, and the water inlet groove are all provided on the front cover.

[0013] According to one embodiment of the present invention, the first nozzle and the second nozzle are coaxially arranged, and the minimum orifice diameter of the first nozzle is less than or equal to the minimum orifice diameter of the second nozzle.

[0014] According to one embodiment of the present invention, the first water passage cavity and the first nozzle are coaxially arranged, the second water passage cavity and the second nozzle are coaxially arranged, and the water passage cavity is sprayed out from the first nozzle and then passes through the second water passage cavity and the second nozzle in sequence.

[0015] According to one embodiment of the present invention, the cross-sectional shape of the second nozzle is circular or an outwardly expanding conical structure.

[0016] According to another aspect of this disclosure, a smart toilet is provided, comprising a multi-water nozzle as described in any of the above claims, a pressure regulating valve, a flow meter, and an instant heating component. The pressure regulating valve and the flow meter are both disposed on the water inlet channel of the multi-water nozzle. The instant heating component is connected to the water inlet channel and is used to heat the water flowing into the multi-water nozzle. The control valve is a water distribution valve or a solenoid valve, and the water distribution valve or the solenoid valve is used to control the on / off state and flow rate of the first water path and / or the second water path.

[0017] As can be seen from the above technical solution, the advantages and positive effects of this utility model are as follows: 1. This utility model, through the combined design of dual water channels (first water channel and second water channel) and control valve, can independently or collaboratively control the on / off state and flow rate of the two water channels, and realize multiple modes such as direct current, spiral flow and mixed flow output from the same spray nozzle, effectively solving the problem of single spray nozzle water type, and can meet different scenarios such as daily cleaning and precise rinsing, as well as the differentiated use needs of adults and children. 2. This utility model stabilizes the water flow through the tubular rectifying structure (straight pipe or gradient pipe) of the first water passage chamber, ensuring uniform DC output without scattering, avoiding incomplete cleaning or discomfort caused by water flow dispersion, and significantly improving cleaning comfort; while the first and second water inlet grooves of the second water passage chamber cooperate with the spiral cavity to form a strong spiral state of water flow, which enhances the rinsing force to improve cleaning efficiency, while avoiding discomfort caused by excessive local rinsing, thus achieving a balance between efficiency and experience. 3. This utility model's technical solution balances practicality and economy. Its main body adopts a split-welded structure of upper cover-face cover-lower cover, allowing for the separate forming of the first and second water passage chambers. This eliminates the need for integrated machining of complex chambers, significantly simplifying processing and reducing production and subsequent maintenance costs. Simultaneously, the dual water passage chambers and dual nozzles are coaxially arranged, with the first nozzle's orifice diameter being smaller than or equal to the second nozzle. This ensures precise focusing when different water patterns are output, avoiding blind spots caused by water pattern deviation, and perfectly fitting the compact installation space inside a smart toilet.

[0018] 4. The nozzle of this utility model has excellent compatibility with the core components of the smart toilet. When used with the pressure stabilizing valve, flow meter and instant heating component, it can achieve stable water pressure and controllable flow, completely avoiding the problem of fluctuating water flow and ensuring stable use. At the same time, the instant heating component can heat the water flow instantly, which is convenient and reduces preheating energy consumption, fully meeting the core needs of smart toilets in terms of energy saving and comfort.

[0028] 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 embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0029] The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0031] like Figures 1-2 As shown, this embodiment provides a multi-water nozzle, including: a body 100, on which a first flow channel 210, a second flow channel 310, a first water passage 220, a second water passage 320, a first nozzle 230, and a second nozzle 340 are provided; the first nozzle 230 and the second nozzle 340 are coaxially arranged; the first flow channel 210, the first water passage 220, and the first nozzle 230 are sequentially connected to form a first water path, and the water sprayed from the first nozzle 230 is sprayed out through the second nozzle 340; the second flow channel 310, the second water passage 320, and the second nozzle 340 are sequentially connected to form a second water path; it also includes a control valve 400, which is used to control the opening and closing of the first water path and / or the second water path and the flow rate; the first water passage 220 or the second water passage 320 is used to convert the water flow state into a direct flow or a spiral flow. It is understood that the "first water path" and the "second water path" are independent and parallel water flow channels, outputting through the same nozzle, namely the second nozzle 340. The "control valve 400" can independently control the on / off state and flow rate of a single water path, or simultaneously control the two water paths to work together. In this embodiment, the first water passage chamber 220 converts the water flow into a direct current, and the second water passage chamber 320 converts the water flow into a spiral flow. The control valve 400 can achieve single output of direct current, single output of spiral flow, or a mixture of both. This allows for the output of multiple water types from the same nozzle, meeting diverse cleaning needs and improving operational flexibility. In other embodiments, more flow channels and water passage chambers can be set to achieve three or more water types output. The control valve 400 can adopt electromagnetic control or mechanical control methods, such as switching valves, water distribution valves, and solenoid valves.

[0032] In some embodiments, such as Figures 1-2 and Figure 4As shown, the first water passage cavity 220 also includes a rectifying structure 221. It can be understood that the "rectifying structure 221" refers to a structure that can streamline the water flow and reduce turbulence, used to convert turbulent water flow into a stable direct current. In this embodiment, the rectifying structure 221 is located between the inlet of the first water passage cavity 220 and the first nozzle 230, so that the water flow forms a vortex-free direct current after rectification. The rectifying structure ensures stable direct current output, avoids water flow scattering, and improves cleaning accuracy and comfort. In other embodiments, the rectifying structure can adopt different forms such as a mesh or a fence, as long as it can achieve the water flow rectification effect.

[0033] In some embodiments, such as Figures 1-2 and Figure 4 As shown, the rectifying structure 221 is a tubular structure of a certain length, which can be a straight pipe or a tapered pipe. It can be understood that a "straight pipe" refers to a tubular structure with a constant inner diameter, and a "tapered pipe" refers to a tubular structure with an inner diameter that gradually decreases or increases along the water flow direction. Both can be used individually or in combination. By guiding the water flow through tubular constraints, turbulence is further eliminated, ensuring direct current stability, and the manufacturing process is simple and easy to implement. In this embodiment, a rib 240 for auxiliary rectification is also provided at the inlet of the first water passage 220. In a specific embodiment below, the rib 240 is located on the upper cover 110.

[0034] In some embodiments, such as Figures 1-2 and Figure 4 , Figure 6 As shown, the second water passage cavity 320 is formed by a boss 321 and a main cavity wall 322. At least one water inlet groove 330 is provided between the boss 321 and the main cavity wall 322, and the water inlet groove 330 connects the second flow channel 310 and the second water passage cavity 320. It can be understood that the "water inlet groove 330" refers to a groove whose water inlet direction forms a certain angle with the axis of the water passage cavity, which is used to allow water to enter the water passage cavity at an inclined angle. In this embodiment, the water flow forms a rotational trend after entering through the water inlet groove 330, laying the foundation for the generation of spiral flow. The structure is compact and easy to form. In other embodiments, the water inlet groove 330 can be inclined in a clockwise or counterclockwise direction, and the number can be set to multiple evenly distributed.

[0035] In some embodiments, such as Figure 6As shown, the water inlet trough 330 includes a first water inlet trough 331 that enters the second water passage chamber 320 along an inclined direction and a second water inlet trough 332 that enters the second water passage chamber 320 along an inclined direction. The water in the first water inlet trough 331 and the second water inlet trough 332 flows in the same direction after entering the second water passage chamber 320. The water flows into the second water passage chamber 320 at an inclined direction along the first water inlet trough 331 and the second water inlet trough 332, respectively, forming a bidirectional rotational driving force. In this embodiment, the rotational forces generated by the bidirectional water inlet are superimposed, enhancing the rotational intensity of the spiral flow and improving the rinsing force. In other embodiments, multiple sets of symmetrical water inlet troughs 330 can be set, and the inclination angle can be adjusted within the range of 30°-60°. Of course, the water can also enter the second water passage chamber 320 along the tangential direction of the second water passage chamber 320.

[0036] In some embodiments, such as Figures 1-2 and Figure 4 , Figure 6 As shown, the second water passage cavity 320 is provided with a spiral cavity, which connects to the water inlet trough 330. The boss 321 is recessed inward and encloses the main cavity wall 322 of the cover 120 to form the spiral cavity. It can be understood that the "spiral cavity" can refer to a cavity with a spiral guiding structure on the inner wall, which is used to guide the water flow to form a regular spiral motion and improve cleaning efficiency. The boss 321 being recessed inward means that the boss 321 is recessed towards the second water passage cavity 320.

[0037] Specifically, when the first flow channel 210 at the water inlet end is connected to the first water passage 220, the water flow is rectified by the first water passage 220 and then sprayed out as a column of water from the first nozzle 230, which is water type I. The column of water is then sprayed out through the second nozzle 340. When the second flow channel 310 at the water inlet end is connected to the second water passage 320, the water flows through the second water passage 320 and accelerates under the water inlet groove 330 of the second water passage 320 to spray out hollow dispersed water from the second nozzle 340, which is water type II. Water type I and water type II are single-mode water discharge, or water can be introduced into the first flow channel 210 and the second flow channel 310 at the same time to form a third type of water type III.

[0038] In some embodiments, such as Figures 3-4 As shown, the main body 100 includes an upper cover 110, a face cover 120 and a lower cover 130. The upper cover 110 and the face cover 120 are welded together to form a first water passage cavity 220, and the lower cover 130 and the face cover 120 are welded together to form a second water passage cavity 320. The boss 321, the main cavity wall 322 and the water inlet groove 330 are all provided on the face cover 120.

[0039] It is understood that the main body 100 adopts a split design, assembled by welding, with each component forming a complex chamber structure. This embodiment reduces the processing difficulty of complex chambers, facilitates mass production, and improves structural sealing. In other embodiments, assembly can be achieved using snap-fit ​​connections or adhesive bonding.

[0040] In some embodiments, such as Figures 1-2 As shown, the first nozzle 230 and the second nozzle 340 are coaxially arranged, and the minimum orifice diameter of the first nozzle 230 is less than or equal to the minimum orifice diameter of the second nozzle 340.

[0041] In some embodiments, the first water passage chamber 220 and the first nozzle 230 are coaxially arranged, as are the second water passage chamber 320 and the second nozzle 340. Water exiting the first water passage chamber 220 from the first nozzle 230 passes sequentially through the second water passage chamber 320 and the second nozzle 340. It can be understood that "coaxial arrangement" means that the axes of all components coincide, the first water passage chamber 220 and the second water passage chamber 320 are distributed in an upper and lower structure, and water passing through the first water passage chamber 220 can be sprayed out from the second nozzle 340. This example structure can avoid water flow deviation, ensure that water from the first water passage chamber 220 and the second water passage chamber 320 can be sprayed out from the same outlet, and ensure consistent rinsing positions for different water types, thus improving the user experience.

[0042] In other embodiments, such as Figures 5-6 As shown, the multi-water nozzle is also provided with a third flow channel 510 and a fourth flow channel 520 that are connected to another nozzle outlet. The third flow channel 510 is arranged in the same layer as the first flow channel 210, and the fourth flow channel 520 is arranged in the same layer as the second flow channel 310.

[0043] In some embodiments, such as Figure 2 As shown, the cross-sectional shape of the second nozzle 340 is either circular or an outwardly expanding conical structure. It can be understood that a "conical structure" refers to a nozzle cross-section that gradually expands along the water flow direction, forming a diffused water output. In this embodiment, the circular nozzle ensures concentrated spiral flow, while the conical structure expands the rinsing range to adapt to different cleaning needs.

[0044] like Figure 7 As shown, this embodiment provides a smart toilet, including a multi-water nozzle as described in any of the above embodiments, a pressure regulating valve, a flow meter, and an instant heating component. The pressure regulating valve and flow meter are both located on the water inlet channel of the multi-water nozzle; the instant heating component is connected to the water inlet channel and is used to heat the water flowing into the multi-water nozzle. It is understood that the components work together to respectively achieve water pressure stabilization, flow monitoring, and water temperature control functions, ensuring stable water flow and suitable temperature, thus improving the comfort and safety of using the multi-water nozzle. In other embodiments, a water filtration component can be added, and the instant heating component can adopt an instant electric heating element or a semiconductor heating method.

[0045] It should be understood that the various examples described above can be utilized in multiple directions (e.g., tilted, inverted, horizontal, vertical, etc.) and in multiple configurations without departing from the principles of this invention. The embodiments shown in the accompanying drawings are merely examples of effective application of the principles of this invention, and the invention is not limited to any specific details of these embodiments.

[0046] Of course, upon careful consideration of the above description of the representative embodiments, those skilled in the art will readily understand that various modifications, additions, substitutions, deletions, and other changes can be made to these specific embodiments, and that such changes are within the scope of the principles of this invention. Therefore, the foregoing detailed description should be clearly understood as being given by way of illustration and example only, and the spirit and scope of this invention are defined solely by the appended claims and their equivalents.
