Description

Technical Field

[0001] The present application relates to the technical field of bathroom equipment, and in particular to a toilet foaming system and a control method for an intelligent toilet. Background Art

[0002] As a key component of modern bathroom fixtures, smart toilets are constantly evolving to enhance user experience. The "Foam Shield" feature, which pre-sprays a dense layer of foam onto the toilet's water seal, effectively prevents splashing, reduces odor spread, and enhances cleaning effectiveness. It has become a hallmark feature of mid-range and high-end smart toilets.

[0003] Currently, there are two main technical approaches to achieving foaming in smart toilet foam shields. The first solution relies on an independent, electrically controlled waterway switching valve and a dedicated diaphragm pump: the waterway switching valve is responsible for connecting the foam liquid waterway, while the diaphragm pump is dedicated to extracting the foam stock and delivering it to the foaming device. While this solution can ensure effective foaming, it requires the addition of a waterway switching valve and diaphragm pump, resulting in a complex system structure and significantly increased component costs. The second solution uses a mechanical pumping mechanism (such as utilizing the Venturi effect or a piston), and its foaming process relies on the pressure of the toilet's inlet waterway. While this solution reduces the cost of a dedicated pump, it still requires a waterway switching valve to connect the pressurized waterway, and its foaming effect is highly dependent on the inlet water pressure. When encountering low water pressure conditions, the driving water pressure is insufficient, resulting in difficulty in extracting the foam liquid, inadequate mixing, a significant reduction in foaming volume, a thin foam layer, or even failure, significantly reducing the user experience. Summary of the Invention

[0004] The present application provides a toilet foaming system and a control method for an intelligent toilet to solve the problem of significantly reducing system costs while ensuring stable and efficient foaming under low water pressure conditions.

[0005] In a first aspect, the present application provides a toilet foaming system, comprising:

[0006] A cleaning device comprising a water pressure control member, a water distribution member, and a nozzle assembly connected in sequence, wherein the water distribution member comprises a water inlet, a first water outlet, and a second water outlet, the water inlet being connected to the output end of the water pressure control member, and the first water outlet being connected to the input end of the nozzle assembly;

[0007] The foaming assembly includes a liquid storage device, a mixing device, and a liquid pumping device, wherein the liquid storage device is suitable for storing a foaming agent, the mixing device is suitable for mixing the foaming agent and water, and the liquid pumping device is connected to the liquid storage device, the mixing device, and the second water outlet, respectively;

[0008] A first control module is electrically connected to the water pressure control component, the water distribution component and the mixing device, respectively. The first control module is suitable for obtaining a first control instruction and controlling the water distribution component to open the second water outlet, the water pressure control component and the mixing device according to the first control instruction; wherein the first control instruction is issued by the control terminal.

[0009] Beneficial Effects: By reusing water distribution components to switch water paths, the system eliminates the need for independent water path switching valves, achieving zero-cost water path switching. The foaming assembly also shares a water pressure control unit with the cleaning device to boost the foaming pumping pressure, eliminating the need for a dedicated foaming diaphragm pump and reducing the number of core components. The water pressure control unit actively boosts the foaming water path, ensuring stable foaming even at low water pressures, resolving the water pressure dependency of traditional mechanical structures.

[0010] In an optional embodiment, the water pressure control component includes a water supply pump, the input end of the water supply pump is used to communicate with an external water source; the output end of the water supply pump is connected to a water inlet.

[0011] Beneficial effects: The water supply pump can boost the pressure for foaming liquid extraction, eliminating the need for a dedicated foaming diaphragm pump and reducing the number of core components.

[0012] In an optional embodiment, the water pressure control component further includes a pressure stabilizer, an input end of the pressure stabilizer is connected to the external water source, and an output end of the pressure stabilizer is connected to the water inlet.

[0013] Beneficial effect: The pressure stabilizing valve can be used to balance water pressure fluctuations, thereby ensuring the reliability of foaming and cleaning.

[0014] In an optional embodiment, the method further includes:

[0015] The second control module is electrically connected to the water pressure control component, the water distribution component and the nozzle assembly, respectively. The second control module is suitable for obtaining a second control instruction and controlling the water distribution component to open the first water outlet, the water pressure control component and the nozzle assembly according to the second control instruction, wherein the second control instruction is issued by the control terminal.

[0016] Beneficial Effects: The second control module is set up separately from the first control module, which can realize the separation of cleaning and foaming control logic, reducing system complexity. At the same time, the second control module cooperates with the first control module to achieve efficient dual-mode switching without interfering with each other.

[0017] In an optional embodiment, the liquid pumping device includes:

[0018] shell;

[0019] a piston body slidably disposed in the housing along the axial direction of the housing, the piston body dividing the inner cavity of the housing into a liquid storage cavity and a pressure cavity, the pressure cavity being provided with a water supply interface and a drainage interface, the water supply interface being in communication with the second water outlet, and the drainage interface being in communication with the mixing device;

[0020] An elastic member is arranged in the pressure chamber, and the elastic member has a tendency to drive the piston body away from the water supply interface.

[0021] Beneficial Effects: The pumping device is a mechanical pumping mechanism that requires no additional electricity. It operates automatically based on water pressure, thanks to the reset effect of the elastic element and the water pressure supplied by the hydraulic control element. Compared to electronic pumps, it is more wear-resistant and has improved long-term stability. Water pumped into the water supply interface not only provides water pressure to the pressure chamber, driving the piston to move, but also enters the mixing device through the drainage interface to mix with the foaming agent, saving manufacturing costs.

[0022] In an optional embodiment, the liquid storage chamber is provided with a liquid inlet interface and a liquid discharge interface, the liquid inlet interface is communicated with the liquid storage device, and the liquid discharge interface is communicated with the mixing device.

[0023] Beneficial effects: The water pumped into the water supply interface is used to provide water pressure to the pressure chamber, driving the piston body to move, thereby compressing the space of the liquid storage chamber, and squeezing the foaming agent in the liquid storage chamber into the mixing device. When the foaming is completed and the water supply is stopped, the setting of the elastic part can pull the piston body back, so that the liquid storage chamber is in a negative pressure state, and then the foaming agent in the liquid storage device is sucked into the liquid storage chamber again for use in the next foaming.

[0024] In an optional embodiment, the mixing device comprises:

[0025] a box body, the inner cavity of which is in communication with the liquid discharge interface and the water discharge interface;

[0026] A mixing component is disposed in the box body;

[0027] The foam nozzle is communicated with the inner cavity of the box body and is suitable for spraying water and foaming agent in the box body.

[0028] Beneficial effect: By integrating the box body and the mixing component, not only can space be saved, but also the length of the pipeline can be shortened, and the mixing efficiency of the foaming agent and water can be improved.

[0029] In an optional implementation, the first control module and the second control module are integrated on a circuit board, and the control terminal includes the circuit board.

[0030] Beneficial effects: Integrating the first control module and the second control module can reduce the number of circuit boards, simplify the assembly process, and reduce material costs.

[0031] In a second aspect, the present application also provides a method for controlling a smart toilet, comprising:

[0032] Obtaining a first control instruction;

[0033] Controlling the water distribution element to open the second water outlet, the water pressure control element and the mixing device according to the first control instruction; wherein the first control instruction is issued by the control terminal;

[0034] Obtaining a second control instruction;

[0035] According to the second control instruction, the water distribution component is controlled to open the first water outlet, the water pressure control component and the nozzle assembly; wherein, the second control instruction is issued by the control terminal.

[0036] Benefits: The cleaning and foaming devices share the same hydraulic control unit, allowing them to switch between cleaning and foaming as needed, maximizing the use of existing components and saving manufacturing costs. Independent control of the cleaning and foaming modes ensures instantaneous response from the cleaning action and the foam shield, preventing them from interfering with each other and optimizing the user experience.

[0044] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0045] The following combination Figures 1 to 4 , describing the embodiments of the present application.

[0046] According to an embodiment of the present application, in one aspect, a toilet foaming system is provided, comprising a cleaning device, a foaming assembly, and a first control module. The cleaning device comprises a water pressure control member, a water distribution member 2, and a nozzle assembly 3, which are connected in sequence. The water distribution member 2 comprises a water inlet 201, a first water outlet 202, and a second water outlet 203. The water inlet 201 is connected to the output end of the water pressure control member, and the first water outlet 202 is connected to the input end of the nozzle assembly 3. The foaming assembly comprises a liquid storage device, a mixing device 6, and a liquid pumping device 5. The liquid storage device is suitable for storing foaming agent, and the mixing device 6 is suitable for mixing the foaming agent and water. The liquid pumping device 5 is respectively connected to the liquid storage device, the mixing device 6, and the second water outlet 203. The first control module is electrically connected to the water pressure control member, the water distribution member 2, and the mixing device 6. The first control module is suitable for receiving a first control instruction and, in accordance with the first control instruction, controlling the water distribution member 2 to open the second water outlet 203, the water pressure control member, and the mixing device 6; wherein the first control instruction is issued by a control terminal.

[0047] It should be noted that the pumping device 5 is adapted to draw the foaming agent from the liquid storage device and discharge it into the mixing device 6, and is also adapted to direct the second water outlet 203 into the mixing device 6. The pumping device 5 can be configured as a hydraulic piston, with the power used by the pumping device 5 to discharge the foaming agent into the mixing device 6 being generated by converting the incoming water pressure. Furthermore, water entering the pumping device 5 through the second water outlet 203 not only serves to provide hydraulic pressure but also, after entering the pumping device 5, re-enters the mixing device 6 to serve as water for foaming. The water diverter 2 can be configured as a water diverter valve.

[0048] Among them, the nozzle assembly 3 is an existing technology commonly used in intelligent toilet cleaning devices, including multiple cleaning modes, such as hip washing, feminine washing, etc., so the corresponding first water outlet 202 can be set in multiple ways, and the interfaces of different cleaning modes are connected.

[0049] It can be understood that when the first control module controls the operation of the water pressure control component, the water distribution component 2 and the mixing device 6, the second water outlet 203 is in the open state, the first water outlet 202 is in the closed state, and the nozzle assembly 3 is also in the closed state, which can avoid the cleaning action and the foaming action running at the same time, affecting the formation of the foam shield.

[0050] In this embodiment, waterway switching is achieved by reusing the water diverter 2, eliminating the need for a separate waterway switching valve, achieving zero-cost waterway switching. The foaming assembly also shares a water pressure control unit with the cleaning device for foaming, pumping, and pressurizing the liquid, eliminating the need for a dedicated foaming diaphragm pump and reducing the number of core components. The water pressure control unit actively boosts the foaming waterway, ensuring stable foaming even at low water pressures, resolving the water pressure dependency of traditional mechanical structures.

[0051] In one embodiment, the water pressure control component includes: a water supply pump 1 , wherein the input end of the water supply pump 1 is used to communicate with an external water source; and the output end of the water supply pump 1 is communicated with the water inlet 201 .

[0052] In one embodiment, the water pressure control component further includes a pressure stabilizer 7 , an input end of the pressure stabilizer 7 is connected to an external water source, and an output end of the pressure stabilizer 7 is connected to an input end of the water supply pump 1 .

[0053] In one embodiment, the cleaning device further includes an angle valve 9 , which includes a water inlet and a water outlet. The water inlet of the angle valve 9 is used to communicate with an external water source; the input end of the water pressure control component is connected to the water outlet of the angle valve 9 .

[0054] It can be understood that the angle valve 9 can serve as a common structure for the cleaning device and the foaming component, which can meet the water demand for cleaning and foaming, ensure the operation of two independent structures, and achieve the stability of water supply.

[0055] In this embodiment, by setting an angle valve 9, direct connection with an external water source can be achieved. When the foaming component needs to foam or the cleaning device needs to be cleaned, the angle valve 9 can directly supply the water provided by the external water source to the water pressure control component to achieve pumping connection of the water path. Even if the external water source is in a low-pressure state, the water pressure supplied to the foaming component can be guaranteed through the setting of the water pressure control component, thereby ensuring the normal operation of the foaming function of the foaming component.

[0056] In one embodiment, the cleaning device further includes a vacuum breaker 8 , the pressure stabilizer 7 is connected to the vacuum breaker 8 , the input end of the pressure stabilizer 7 is connected to an external water source, and the vacuum breaker 8 is connected to the input end of the water pressure control element.

[0057] It should be noted that the pressure stabilizer 7 and the vacuum breaker 8 are commonly used structures in smart toilets. They can not only act on the cleaning function of the cleaning device, but also ensure the stability of the water supply when used for the foaming function, thereby ensuring the stability of the water pressure of the pumping device 5 and the water pressure entering the mixing device 6, and further ensuring the foaming effect.

[0058] Optionally, the other interface of the voltage stabilizer 7 is connected to the angle valve 9 through a pipeline, and is connected to the pipeline of the external water source through the angle valve 9, so that the external water source can be connected or disconnected, which is convenient for the later maintenance of the smart toilet.

[0059] Optionally, the pressure stabilizing element may be configured as a pressure stabilizing valve.

[0060] In this embodiment, a pressure stabilizing valve is provided to balance water pressure fluctuations, and the vacuum breaker 8 can prevent siphon contamination, thereby ensuring the reliability of foaming and cleaning.

[0061] In one embodiment, the cleaning device further includes a heating component 4 including an input end and an output end. The input end of the heating component 4 is connected to the output end of the water pressure control component, and the output end of the heating component 4 is connected to the water inlet 201 .

[0062] It is understandable that the heating component 4 can be configured as a heater. The heating component 4 is an indispensable component of the intelligent toilet cleaning device. It can heat the water in the waterway when the cleaning device is spraying water for cleaning, ensuring the user's comfort during the cleaning process. In addition, during the reuse of the cleaning device and the foaming component, the heating component 4 can be in a working state where water is kept flowing but no heating is performed to avoid affecting the foaming. It is also possible to control the temperature of the heating component 4 during the foaming process, and to control the temperature of the water entering the mixing device 6, which can further improve the foaming effect.

[0063] In this embodiment, the heating component 4 is used to clean the water channel and heat the water sprayed by the cleaning device. When the foaming action is performed, the heating component 4 is in a heating stop state, but still maintains the circulation of the water channel.

[0064] In one embodiment, a second control module is further included, which is electrically connected to the heating component 4, the water pressure control component, the water distribution component 2 and the nozzle assembly 3 respectively. The second control module is suitable for obtaining a second control instruction and controlling the water distribution component 2 to open the first water outlet 202, turn on the heating component 4, the water pressure control component and the nozzle assembly 3 according to the second control instruction, wherein the second control instruction is issued by the control terminal.

[0065] It should be noted that the first control module and the second control module are independent control components and operate asynchronously. While the second control module is controlling the operation of the heating assembly 4, the water pressure control component, the water distribution component 2, and the nozzle assembly 3, the second water outlet 203 and the mixing device 6 are both in a stopped state.

[0066] In this embodiment, the second control module is independently configured from the first control module to separate the cleaning and foaming control logics, reducing system complexity. Furthermore, the second control module works in conjunction with the first control module to achieve efficient dual-mode switching without interfering with each other.

[0067] In one embodiment, the liquid pumping device 5 includes a housing 501, a piston body 502, and an elastic member 507. The piston body 502 is slidably disposed within the housing 501 along the axial direction of the housing 501. The piston body 502 divides the inner cavity of the housing 501 into a liquid storage chamber 503 and a pressure chamber 504. The pressure chamber 504 is provided with a water supply interface 505 and a drainage interface 506. The water supply interface 505 is connected to the second water outlet 203, and the drainage interface 506 is connected to the mixing device 6. The elastic member 507 is disposed within the pressure chamber 504 and has a tendency to drive the piston body 502 away from the water supply interface 505.

[0068] It is understood that the elastic member 507 can be configured as a spring, and the elastic member 507 includes a first end and a second end that are opposite to each other, the first end of the elastic member 507 being connected to the piston body 502, and the second end of the elastic member 507 being connected to the inner wall of the pressure chamber 504. Alternatively, the diameter of the elastic member 507 can be increased, and the housing 501 can be configured as a cylindrical structure simultaneously, so that the diameter of the elastic member 507 is close to the inner diameter of the housing 501. In this case, the inner wall of the housing 501 can limit the elastic member 507, and the first end and / or second end of the elastic member 507 may not need to be fixed.

[0069] Optionally, the piston body 502 can be made of rubber material, and the outer edge of the piston body 502 is in sliding contact with the inner wall of the shell 501, and the shape is adapted to achieve sealed separation of the pressure chamber 504 and the liquid storage chamber 503 to avoid liquid leakage or water leakage.

[0070] It should be noted that the liquid pumping device 5 is a common structure in the foaming device of the smart toilet.

[0071] In this embodiment, the pumping device 5 is configured as a mechanical pumping structure, requiring no additional electricity. It operates automatically based on water pressure, thanks to the resetting effect of the elastic member 507 and the water pressure supplied by the water pressure control element. Compared to electronic pumps, it is more wear-resistant and improves long-term stability. Water pumped into the water supply port 505 not only provides water pressure to the pressure chamber 504, driving the piston body 502 to move, but also enters the mixing device 6 through the drainage port 506 to mix with the foaming agent, saving manufacturing costs.

[0072] In one embodiment, the liquid storage chamber 503 is provided with a liquid inlet interface 508 and a liquid discharge interface 509 , the liquid inlet interface 508 is communicated with the liquid storage device, and the liquid discharge interface 509 is communicated with the mixing device 6 .

[0073] As will be appreciated, both the liquid inlet port 508 and the liquid discharge port 509 are in communication with the liquid storage chamber 503. A one-way valve is provided on the pipeline connecting the liquid inlet port 508 and the liquid storage device to prevent the foaming agent in the liquid storage chamber 503 from returning to the liquid storage device during the process of compressing and discharging the liquid from the liquid storage chamber 503. Furthermore, a one-way valve may also be provided on the pipeline between the liquid discharge port 509 and the mixing device 6 to prevent residual mixed liquid in the mixing device 6 from being drawn into the liquid storage chamber 503 when negative pressure is generated in the liquid storage chamber 503.

[0074] The liquid storage device can also be configured as a box-shaped structure with a cavity, wherein the cavity inside is used to load the foaming agent. At the same time, a first interface is provided at the bottom of the liquid storage device for connecting to the liquid inlet interface 508, and a second interface is provided at the top or side of the liquid storage device for replenishing the foaming agent, and an end cover is provided simultaneously for sealing the second interface.

[0075] In this embodiment, the water pumped into the water supply interface 505 is used to provide water pressure to the pressure chamber 504, drive the piston body 502 to move, and then compress the space of the liquid storage chamber 503, so as to squeeze the foaming agent in the liquid storage chamber 503 into the mixing device 6. When the foaming is completed and the water supply is stopped, the setting of the elastic member 507 can pull back the piston body 502, so that the liquid storage chamber 503 is in a negative pressure state, and then the foaming agent in the liquid storage device is sucked into the liquid storage chamber 503 again for use in the next foaming.

[0076] In one embodiment, the mixing device 6 includes a housing 601, a mixing assembly, and a foam nozzle 602. The interior of the housing 601 is connected to the liquid discharge port 509 and the water discharge port 506. The mixing assembly is disposed within the housing 601. The foam nozzle 602 is connected to the interior of the housing 601 and is adapted to spray the water and foaming agent within the housing 601.

[0077] It should be noted that the mixing component is a common structure in smart toilets, which is used to preliminarily mix the foaming agent and water entering the box body 601 to improve the foaming effect during the foaming process.

[0078] In this embodiment, by integrating the box body 601 and the mixing assembly, not only space can be saved, but also the length of the pipeline can be shortened, thereby improving the mixing efficiency of the foaming agent and water.

[0079] In one embodiment, the first control module and the second control module are integrated on a circuit board, and the control terminal includes the circuit board.

[0080] It should be noted that the circuit board is provided with a signal receiving and transmitting module for receiving instructions from the user terminal and respectively operating the first control module and the second control module. At the same time, the operating order of the first control module and the second control module can also be controlled by a preset program.

[0081] In this embodiment, the first control module and the second control module are integrated to reduce the number of circuit boards, simplify the assembly process, and lower material costs.

[0082] According to another embodiment of the present application, a method for controlling a smart toilet is provided, comprising obtaining a first control instruction. Based on the first control instruction, the method controls the water distribution component 2 to open the second water outlet 203, the water pressure control component, and the mixing device 6; wherein the first control instruction is issued by a control terminal. Furthermore, a second control instruction is obtained. Based on the second control instruction, the method controls the water distribution component 2 to open the first water outlet 202, the heating component 4, the water pressure control component, and the nozzle assembly 3; wherein the second control instruction is issued by the control terminal.

[0083] In this embodiment, the cleaning and foaming devices share the same hydraulic control unit, switching between cleaning and foaming as needed. This maximizes the use of existing components and reduces manufacturing costs. Furthermore, independent control of the cleaning and foaming modes ensures instantaneous response of the cleaning action and the foam shield, preventing them from interfering with each other and optimizing the user experience.

[0084] Although the embodiments of the present application have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the appended claims.
