Description

Technical Field

[0001] The utility model relates to a cleaning water channel of an intelligent toilet and an intelligent toilet, belonging to the field of kitchen and sanitary ware. Background Art

[0002] Microbubble technology has been widely used in the field of water treatment due to its unique sterilization and decontamination properties, and has been maturely integrated into household sanitary ware, such as the water outlet system of faucets and showers. This type of device introduces microbubbles so that when the water flows in contact with the surface, the microbubbles release energy at the moment of bursting, effectively stripping and removing stains. At the same time, the local high-pressure environment generated has a significant inactivation effect on microorganisms attached to the surface, thereby improving the cleaning effect and hygiene level.

[0003] However, the application of microbubble technology in smart toilets is relatively lagging. This is mainly because the inherent characteristics of smart toilet flushing systems are significantly different from traditional faucets and showers, which makes the direct transplantation of microbubble technology challenging.

[0004] The cleaning water circuit design of smart toilets usually does not have a high water inlet pressure comparable to that of faucets. Faucets and showers are often directly connected to the water supply mains, which can obtain sufficient water pressure, so as to form a stable and dense flow of microbubbles near the water outlet. In contrast, the cleaning system of smart toilets is often strictly controlled by internal pressure stabilizing and limiting devices, which aims to protect the water circuit and its precision accessories from excessive water pressure shock and prevent potential damage risks. Compared with the high-flow flushing of faucets and showers, smart toilet cleaning usually uses a smaller water flow. Such a water inlet design limits the ability to generate and maintain a sufficient number of microbubbles.

[0005] Therefore, how to successfully introduce microbubble technology into the cleaning water circuit of smart toilets is a challenge faced by technicians in this field. Summary of the invention

[0006] The utility model provides a cleaning water channel of an intelligent toilet and an intelligent toilet, which integrate a micro-bubble generating technology and can generate micro-bubbles in the cleaning water channel of the intelligent toilet, thereby providing a more hygienic, efficient and comfortable cleaning experience for users.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0009] Preferably, a second three-way pipe fitting is further included, and the air outlet of the air pump, the second water inlet of the switching valve, and the first three-way pipe fitting opening C1 are respectively connected to the second three-way pipe fitting openings A2, B2, and C2, so that when the water pump is working, part of the water flowing from the first water inlet of the switching valve to the water outlet of the switching valve flows back to the second three-way pipe fitting opening B2 through the second water inlet of the switching valve, and then is connected to the water inlet of the water pump through the first three-way pipe fitting opening B1.

[0010] Preferably, the cleaning water circuit is also configured that, when the water pump is not working, the water at the water inlet end is divided into a first water circuit and a second water circuit and flows to the switching valve; part of the water at the water inlet end of the first water circuit flows to B1 through the first three-way pipe opening A1, and then flows to the first water inlet of the switching valve through the water pump and the microbubble generator; part of the water at the water inlet end of the second water circuit flows to B2 through the first three-way pipe opening C1 and the second three-way pipe opening C2; at the same time, the gas flowing out of the air pump flows to B2 through the second three-way pipe opening A2, and the mixed gas and liquid flow together to the second water inlet of the switching valve.

[0011] Preferably, an electromagnetic pressure-stabilizing valve is further provided, the water inlet end is connected to the water inlet of the electromagnetic pressure-stabilizing valve, and the water outlet of the electromagnetic pressure-stabilizing valve is connected to the opening A1 of the first three-way pipe fitting.

[0012] Preferably, the microbubble generator comprises a jet unit connected to the water inlet of the microbubble generator, the jet unit is provided with a plurality of small holes, a baffle is provided at the rear end of the plurality of small holes, the gas-liquid mixture passes through the plurality of small holes to form a concentrated jet, and then hits the baffle.

[0013] Preferably, the micro-bubble generator further comprises a cavity arranged at the rear end of the baffle, and the cavity is connected to the water outlet of the micro-bubble generator.

[0014] Preferably, a heating component is provided between the electromagnetic pressure-stabilizing valve and the first three-way pipe fitting, and the water at the water inlet end is warm water heated by the heating component.

[0015] Preferably, the switching valve has three water outlets, which are respectively connected to the buttocks washing port, the women's washing port, and the self-cleaning port of the cleaning pipe.

[0017] Preferably, the smart toilet has at least two cleaning modes, the first cleaning mode is a microbubble water cleaning mode in which the water pump and the air pump work simultaneously, and the second cleaning mode is a non-microbubble water cleaning mode in which the water pump is turned off and the air pump is turned on.

[0018] Compared with the prior art, the technical solution of the utility model has the following beneficial effects:

[0019] 1. An innovative reflux water system is introduced, which utilizes the continuous motion characteristics of the circulating water flow to make the air in the water undergo repeated high-intensity shearing, which can enhance the efficiency and total amount of microbubble generation and ensure the efficiency and sufficiency of the microbubble generation process.

[0020] 2. Part of the water flowing from the first water inlet of the switching valve to the water outlet of the switching valve flows back through the second water inlet of the switching valve, which can appropriately reduce the pressure at the water outlet of the microbubble generator, thereby increasing the pressure difference at both ends of the microbubble generator, thereby promoting the effective generation of microbubbles.

[0021] 3. When the water pump is turned off, the first three-way pipe fitting is used to divert the water at the water inlet end. Part of the water flows to the microbubble generator through the water pump, and the other part of the water flows to the second water inlet of the switching valve through the second three-way pipe fitting. Because the microbubble generator has a certain flow limit on the water channel, the water channel passing through the second three-way pipe fitting just plays a complementary role, so that the final water flow rate is sufficient and the flushing force is increased; on the other hand, it can ensure that when the water pump is turned off, the gas output by the air pump can be smoothly introduced into the water channel to achieve effective gas-water mixing.

[0022] 4. Only by adding a water pump and a micro-bubble generator to the existing smart toilet structure can the micro-bubble cleaning function be upgraded at a low cost and with a small footprint. Its advantage lies in the minimal changes to the existing hardware layout. With its excellent adaptability and convenience, the smart toilet can be efficiently transformed into a new device with micro-bubble cleaning capabilities in a short period of time, bringing users a more hygienic and efficient cleaning experience.

[0023] 5. The water path can be changed simply by turning off the water pump, which means that users can freely choose between two or more preset water path modes according to actual needs or personal preferences. This design gives the product rich functionality and scene adaptability, meeting users' needs for personalized experience and diversified application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figures 1 to 3 In this embodiment, a cleaning water circuit of an intelligent toilet includes a water inlet 1, a water pump 2, an air pump 3, a first three-way pipe fitting 4, a switching valve 5, a microbubble generator 6 and a cleaning pipe 7. The water inlet 1, the water inlet of the water pump 2, and the air outlet of the air pump 3 are respectively connected to the openings A1, B1, and C1 of the first three-way pipe fitting 4, the water outlet of the water pump 2 is connected to the water inlet of the microbubble generator 6, the water outlet of the microbubble generator 6 is connected to the first water inlet 51 of the switching valve, the first water inlet 51 and the second water inlet 52 of the switching valve are connected to the water outlet 53 of the switching valve, and the water outlet 53 of the switching valve is connected to the cleaning pipe 7.

[0029] The water inlet 1 is responsible for accessing the water source, and the water pump 2 located behind the water inlet 1 allows the water flow to maintain sufficient pressure and flow rate when entering the microbubble generator. The air pump 3 is used to inject air into the cleaning water path, and then the microbubble generator can evenly disperse the air in the water flow in the form of microbubbles to form a mixed liquid rich in microbubbles.

[0030] The switching valve 5 can accurately control the direction of the water path according to user instructions or preset programs. It contains multiple water outlets, which correspond to different cleaning functions (such as buttocks washing, women's washing, self-cleaning, etc.). Generally, fast switching is achieved through electronic control to ensure that the cleaning water flows accurately to the target area. The number of water outlets of the switching valve is set to 3. These three water outlets are connected to the three outlets of the cleaning pipe 7 respectively. The switching valve can choose to connect the three outlets according to the setting. The three outlets are the buttocks washing port, the women's washing port and the self-cleaning port. The first water outlet of the switching valve is closely connected to the buttocks washing port of the cleaning pipe. When the user selects the buttocks washing mode, the water flow will be directed through this channel to carry out targeted cleaning of the buttocks area. The second water outlet is dedicated to connecting the women's washing port of the cleaning pipe. This function is designed for female users to meet their hygiene needs during their special physiological period. When the women's washing mode is enabled, the water will flow out gently from this water outlet, accurately locate the private area, and provide gentle and thorough cleaning services, reflecting the humanized care and meticulous design concept of the product. The last outlet is connected to the self-cleaning port of the cleaning pipe. In the self-cleaning mode, water will flow through this outlet to self-rinse the cleaning pipe, ensuring that the device remains clean before and after each use.

[0031] In this way, the air provided by the air pump 3 and the water provided by the water inlet 1 are mixed through the first three-way pipe 4 and then enter the water pump 2, and are further provided to the micro-bubble generator 6. The cleaning water circuit is configured such that when the water pump 2 is working, part of the water flowing from the first water inlet 51 of the switching valve to the water outlet 53 of the switching valve flows back to the water inlet of the water pump 2 through the second water inlet 52 of the switching valve. In the water circuit configuration of the cleaning system, the reflux design concept is cleverly used to optimize the generation effect of micro-bubbles.

[0032] Specifically, a second three-way pipe fitting 8 may also be included, and the air outlet of the air pump 3, the second water inlet 52 of the switching valve, and the first three-way pipe fitting opening C1 are respectively connected to the second three-way pipe fitting openings A2, B2, and C2, so that when the water pump 2 is working, part of the water flowing from the first water inlet 51 of the switching valve to the water outlet 53 of the switching valve flows back to the second three-way pipe fitting opening B2 through the second water inlet 52 of the switching valve, and then connected to the water inlet of the water pump 2 through the first three-way pipe fitting opening B1. Of course, in addition to the scheme shown in this embodiment, those skilled in the art should be able to think of more other schemes under the enlightenment of the utility model for how to form a reflux. Undoubtedly, the construction of the reflux mechanism has a variety of possible implementation methods, and the scheme provided in this embodiment is only one of many schemes. In the face of how to form an effective reflux, those skilled in the art should be able to think of more other schemes after deeply understanding and drawing on the core concept of the utility model.

[0033] On the other hand, the cleaning water circuit can also be configured so that when the water pump is not working, the water at the water inlet end is divided into the first water circuit and the second water circuit and flows to the switching valve. The first water circuit is part of the water at the water inlet end flowing to B1 through the first three-way pipe opening A1, and then flowing to the first water inlet of the switching valve through the water pump and the micro-bubble generator. The second water circuit is part of the water at the water inlet end flowing to B2 through the first three-way pipe opening C1 and the second three-way pipe opening C2. At the same time, the gas flowing out of the air pump flows to B2 through the second three-way pipe opening A2, and the mixed gas and liquid flow together to the second water inlet of the switching valve. In this way, the water path can be flexibly switched by simply turning off the water pump, so that users can choose freely from a variety of pre-set water circuit modes according to actual needs or personal preferences. In this way, the product not only has rich functionality, but also greatly enhances its adaptability to various application scenarios, ensuring that users find the perfect fit between personalized experience and diversified usage needs.

[0034] Furthermore, in the system design, a solenoid pressure regulating valve 9 is specially configured to ensure that the water flow pressure between the water inlet end 1 and the subsequent components is stable and controllable. In order to achieve effective management of the water inlet pressure, the water inlet end 1 is connected to the water inlet of the solenoid pressure regulating valve 9, and the water outlet of the solenoid pressure regulating valve 9 is connected to the opening A1 of the first three-way pipe fitting, that is, the water entering the water pump 2 must first pass through the solenoid pressure regulating valve. Preferably, a heating component can be set between the solenoid pressure regulating valve and the first three-way pipe fitting, and the water at the water inlet end is warm water heated by the heating component.

[0035] The microbubble generator 6 selected by the utility model includes a jet unit 61 connected to the water inlet of the microbubble generator, and a series of small holes 62 with small apertures are arranged on the surface of the jet unit. When the gas-liquid mixture passes through the jet unit, it will be ejected from the small holes at high speed to form a plurality of concentrated jet beams, which have high initial kinetic energy and local flow velocity, and are rapidly mixed with the surrounding water flow. Since the jet velocity is much higher than the mainstream velocity, there is a significant speed difference between the two, resulting in strong shear stress. This shearing action forces the large volume bubbles in the jet to be torn into numerous tiny bubbles in a short time.

[0036] At the rear end of the jet unit, a baffle 63 is provided. The baffle corresponds to the positions of the multiple small holes on the jet unit, and its main function is to block and disperse the jet in a targeted manner. When the concentrated jet beam hits the baffle, the blocking effect of the baffle on the jet induces strong local turbulence. The jet is repeatedly stretched, folded and sheared in the turbulent field, so that the bubbles that have not been fully refined continue to suffer high-intensity crushing, and finally a large number of microbubbles with uniform size and good stability are formed.

[0037] Furthermore, a special cavity 64 is provided at the rear end of the baffle. The existence of the cavity provides a short buffer and stable space for the microbubbles, so that the newly generated microbubbles can further mature in a low shear force environment and reduce unnecessary rupture. The cavity is connected to the water outlet of the microbubble generator to ensure that the fully mixed and stabilized microbubble solution can flow out of the device smoothly for subsequent cleaning. In this way, the microbubble generator achieves efficient jetting, impact crushing and stable generation of microbubbles of the gas-liquid mixture through the coordinated work of the jet unit, the baffle and the cavity.

[0038] The present application further provides a smart toilet, which includes the above-mentioned cleaning water circuit. Further, the smart toilet can have at least two cleaning modes, the first cleaning mode is a microbubble water cleaning mode in which the water pump and the air pump work simultaneously, and the second cleaning mode is a non-microbubble water cleaning mode in which the water pump is turned off and the air pump is turned on.

[0039] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
