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 electronically controlled waterway switching valve and a dedicated diaphragm pump: the waterway switching valve is responsible for connecting the foam liquid waterway, and the diaphragm pump is dedicated to extracting the foam stock liquid and delivering it to the foaming component. Although this solution can guarantee the foaming effect, it requires the additional installation of a waterway switching valve and diaphragm pump, resulting in a complex system structure and a significant increase in component costs. The second solution uses a mechanical liquid extraction structure (such as using the Venturi effect or piston, etc.), and its foaming process relies on the pressure of the toilet water inlet itself. Although this solution reduces the cost of a dedicated pump, it still requires a waterway switching valve to connect the pressure waterway, and its foaming effect is highly dependent on the inlet water pressure. When encountering zero water pressure conditions, the foam liquid cannot be sucked out and the water source cannot be provided, causing the foam layer to fail and the user experience to be greatly reduced. 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 zero water pressure conditions.

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

[0006] A flushing device includes a water tank, a water pump, a water channel switching member, and a flushing assembly that are connected in sequence. The water channel switching member includes a water inlet, a first water outlet, and a second water outlet. The water inlet is connected to the output end of the water pump, and the first water outlet is connected to the input end of the flushing 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] The first control module is electrically connected to the water pump, the water circuit switching component and the mixing device respectively. The first control module is suitable for obtaining a first control instruction and controlling the water circuit switching component to open the second water outlet, the water pump and the mixing device according to the first control instruction; wherein, the first control instruction is issued by the control terminal.

[0009] Beneficial Effects: The second outlet of the waterway switching element connects to the pumping device, which shares a single pump with the flushing device. This eliminates the need for a separate waterway switching valve and foaming diaphragm pump, enabling zero-cost waterway switching and significantly reducing costs. Utilizing water storage in the water tank and active pressurization by the pump achieves stable foaming at zero water pressure, eliminating the traditional mechanical structure's reliance on tap water pressure and breaking through water pressure limitations. Furthermore, the pump continuously pressurizes the mechanical pumping device, ensuring the proper function of the foam shield at zero water pressure, thereby enhancing system reliability.

[0010] In an optional embodiment, the flushing assembly includes:

[0011] The upper flushing nozzle and the bottom flushing nozzle are provided with two first water outlets, and the two first water outlets are respectively connected to the upper flushing nozzle and the bottom flushing nozzle.

[0012] Beneficial effect: The dual nozzle design of the upper and lower nozzles allows the flushing functions to remain independent and ensures that the foaming water circuit reuse switching valve does not affect the original flushing performance.

[0013] In an optional embodiment, the method further includes:

[0014] The second control module is electrically connected to the water pump and the water circuit switching component respectively. The second control module is suitable for obtaining a second control instruction and, according to the second control instruction, controlling the water circuit switching component to open the first water outlet and control the opening of the water pump, wherein the second control instruction is issued by the control terminal.

[0015] Beneficial Effects: The same pump can be used in both flushing and foaming modes in a time-sharing manner, maximizing hardware utilization and enabling efficient resource reuse. The independent configuration of the first and second control modules prevents interference between foaming and flushing commands, improving system stability and achieving functional isolation.

[0016] In an optional embodiment, the flushing device further includes:

[0017] The water supply component comprises a water inlet and a water outlet. The water inlet of the water supply component is used to communicate with an external water source, and the water outlet of the water supply component is communicated with the water tank.

[0018] Beneficial Effect: The water tank is used as an independent water storage unit to provide water for the water pump, avoiding the dependence of the foaming function on tap water pressure. At the same time, the water supply component is used to supply water to the water tank to ensure that there is sufficient water in the water tank for flushing and foaming.

[0019] Beneficial Effects: The water inlet valve connects to an external water source, enabling on / off connections and facilitating subsequent maintenance and repair of the smart toilet. The water inlet valve introduces external water into the water tank, thereby replenishing the water. Furthermore, the water inlet valve controls the water level in the tank, ensuring a constant water supply.

[0020] In an optional embodiment, the liquid pumping device includes:

[0021] shell;

[0022] 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;

[0023] 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.

[0024] Beneficial Effects: The mechanical pumping system relies solely on water pressure and the resetting of elastic components, eliminating the need for additional power supply and achieving zero power consumption. Simultaneously, the pump actively increases pressure in the pressure chamber to drive the piston, overcoming the failure of traditional mechanical structures at zero water pressure.

[0025] 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.

[0026] 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.

[0027] In an optional embodiment, the mixing device comprises:

[0028] The box body has an inner cavity connected to the liquid discharge interface and the water discharge interface;

[0029] A mixing component is disposed in the box body;

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0035] Obtaining a first control instruction;

[0036] Controlling the water channel switching component to open the second water outlet, the water pump and the mixing device according to the first control instruction; wherein the first control instruction is issued by the control terminal;

[0037] Obtaining a second control instruction;

[0038] According to the second control instruction, the water channel switching component is controlled to open the first water outlet and control the water pump to be turned on; wherein, the second control instruction is issued by the control terminal.

[0039] Beneficial Effects: The flushing device and foaming component share the same pump, switching between flushing and foaming functions as needed, maximizing the use of existing components and reducing manufacturing costs. Independent control of the flushing and foaming modes ensures instantaneous response from the flushing action and the foam shield, preventing them from interfering with each other and optimizing the user experience. In foaming mode, the pump's forced water supply ensures the pumping device can continue to operate even without mains water pressure, ensuring a zero-water-pressure process.

DETAILED DESCRIPTION

[0048] 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.

[0049] The following combination Figures 1 to 5 , describing the embodiments of the present application.

[0050] According to an embodiment of the present application, on the one hand, a toilet foaming system is provided, comprising a flushing device, a foaming component, and a first control module. The flushing device comprises a water tank 1, a water pump 2, a water circuit switching component 3, and a flushing component, which are connected in sequence. The water circuit switching component 3 comprises a water inlet 301, a first water outlet 302, and a second water outlet 303. The water inlet 301 is connected to the output end of the water pump 2, and the first water outlet 302 is connected to the input end of the flushing component. The foaming component comprises a liquid storage device, a mixing device 4, and a liquid pumping device 5. The liquid storage device is suitable for storing a foaming agent. The mixing device 4 is suitable for mixing the foaming agent and water. The liquid pumping device 5 is connected to the liquid storage device, the mixing device 4, and the second water outlet 303, respectively. The first control module is electrically connected to the water pump 2, the water circuit switching component 3 and the mixing device 4 respectively. The first control module is suitable for obtaining a first control instruction and controlling the water circuit switching component 3 to open the second water outlet 303, the water pump 2 and the mixing device 4 according to the first control instruction; wherein the first control instruction is issued by the control terminal.

[0051] It is understood that the water in the water tank 1 is used not only for the flushing action of the flushing device, but also for the foaming action in the foaming component. This allows the foam shield function to be realized even when the water is cut off, that is, when there is zero water pressure. The water in the water tank 1 can serve as a reserve of water required by the foaming component. When foaming is required, the water in the water tank 1 is pumped out by the water pump 2, which can provide pressure kinetic energy to the liquid pumping device 5 and inject it into the mixing device 4 for mixing with the foaming agent. Specifically, when the first control module controls the operation of the water pump 2, the water channel switching component 3, and the mixing device 4, that is, the second water outlet 303 is in the open state and the first water outlet 302 is in the closed state.

[0052] 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 4, and is also adapted to direct the second water outlet 303 into the mixing device 4. The hydraulic piston structure of the pumping device 5 converts the power used to discharge the foaming agent into the mixing device 4 into the force generated by the incoming water pressure. Furthermore, water entering the pumping device 5 through the second water outlet 303 is not only used to provide water pressure, but can also enter the mixing device 4 after entering the pumping device 5 to serve as foaming water.

[0053] Optionally, the water channel switching component 3 can be configured as a switching valve.

[0054] In this embodiment, the second water outlet 303 of the waterway switching element 3 is connected to the pumping device 5, and the pumping device and the flushing device share a single pump 2. This eliminates the need for a separate waterway switching valve and a foaming diaphragm pump, enabling zero-cost waterway switching and significantly reducing costs. By utilizing water tank 1 for water storage and pump 2 for active pressurization, stable foaming can be achieved at zero water pressure, resolving the traditional mechanical structure's reliance on tap water pressure and breaking through water pressure limitations. Furthermore, pump 2 continuously pressurizes the mechanical pumping device 5, ensuring the proper functioning of the foam shield at zero water pressure and improving system reliability.

[0055] In one embodiment, the flushing assembly includes an upper flushing nozzle 6 and a bottom flushing nozzle 7 , and two first water outlets 302 are provided. The two first water outlets 302 are respectively connected to the upper flushing nozzle 6 and the bottom flushing nozzle 7 .

[0056] It should be noted that the upper flush nozzle 6 and the lower flush nozzle are commonly used structures in smart toilets. The upper flush nozzle 6 is used to spray from the top of the inner wall of the ceramic body 10 and rotate along the inner wall of the ceramic body 10 for cleaning. The lower flush nozzle is used to spray from the water trap of the ceramic body 10, and can flush the dirt in the water trap into the sewage pipe.

[0057] In this embodiment, the dual-nozzle design of the upper flushing nozzle 6 and the bottom flushing nozzle 7 allows the flushing functions to remain independent and ensures that the foaming water circuit reuse switching valve does not affect the original flushing performance.

[0058] In one embodiment, a second control module is further included, which is electrically connected to the water pump 2 and the water circuit switching component 3 respectively. The second control module is suitable for obtaining a second control instruction and, according to the second control instruction, controlling the water circuit switching component 3 to open the first water outlet 302 and control the opening of the water pump 2, and the second control instruction is issued by the control terminal.

[0059] It should be noted that the upper flush nozzle 6 and the lower flush nozzle are connected to the water path switching component 3 through two first water outlets 302 respectively. Therefore, the second control module can also control the opening timing of the two first water outlets 302. First, the water pump 2 and the upper flush nozzle 6 are turned on synchronously, and then the lower flush nozzle is turned on, thereby achieving comprehensive cleaning of the inner cavity of the ceramic body 10.

[0060] In this embodiment, the same pump serves both flushing and foaming modes in a time-sharing manner, maximizing hardware utilization and enabling efficient resource reuse. The independent configuration of the first and second control modules prevents interference between foaming and flushing commands, improving system stability and achieving functional isolation.

[0061] In one embodiment, the flushing device further includes a water supply assembly, including a water inlet and a water outlet. The water inlet of the water supply assembly is connected to an external water source, and the water outlet of the water supply assembly is connected to the water tank 1. The water supply assembly, as a common structure of the flushing device and the foaming assembly, can meet the water needs of flushing and foaming, ensure the operation of the two independent structures, and achieve a stable water supply.

[0062] In this embodiment, the water tank 1 serves as an independent water storage unit, providing a water source for the water pump 2, thereby eliminating the dependence of the foaming function on tap water pressure. Simultaneously, the water supply assembly is used to supply water to the water tank 1 to ensure that there is sufficient water in the water tank 1 for flushing and foaming.

[0063] In one embodiment, the water supply assembly includes a water inlet valve 8 and a water receiving valve 9, which are connected to each other. The water inlet valve 8 is arranged in the water tank 1, and the water receiving valve 9 is connected to an external water source.

[0064] It should be noted that the water inlet valve 9 is set as an angle valve to control the switch of the external water source. The water inlet valve 8 is commonly used in smart toilets, which can realize water replenishment at the lowest water level and stop water supply at the highest water level, thereby ensuring the water reserve in the water tank 1.

[0065] In this embodiment, the water inlet valve 9 is used to connect to an external water source, enabling or disconnecting it, facilitating subsequent maintenance and repair of the smart toilet. The water inlet valve 8 is used to introduce external water into the water tank 1, thereby ensuring water storage within the water tank 1. A float assembly is also provided to control the water level within the water tank 1, ensuring a constant water supply.

[0066] 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 303, and the drainage interface 506 is connected to the mixing device 4. 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.

[0067] It can be understood that the elastic member 507 can be set as a spring, and the elastic member 507 includes a first end and a second end relative to each other, the first end of the elastic member 507 is connected to the piston body 502, and the second end of the elastic member 507 is connected to the inner wall of the pressure chamber 504.

[0068] Optionally, the diameter of the elastic member 507 can be increased, and the shell 501 can be simultaneously set to a cylindrical structure so that the diameter of the elastic member 507 is close to the inner diameter of the shell 501. At this time, the inner wall of the shell 501 can limit the elastic member 507, and there is no need to fix the first end and / or second end of the elastic member 507.

[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 component of the smart toilet.

[0071] In this embodiment, the mechanical pumping operation relies solely on water pressure and the resetting of the elastic member 507, eliminating the need for additional power supply and achieving zero power consumption. Simultaneously, the water pump 2 actively increases pressure in the pressure chamber 504 to drive the movement of the piston 502, overcoming the failure of conventional mechanical structures at zero water pressure.

[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 4 .

[0073] It can be understood that the liquid inlet interface 508 and the liquid discharge interface 509 are both connected to the liquid storage chamber 503. At the same time, a one-way valve is provided on the pipeline connecting the liquid inlet interface 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 compression and discharge process of the liquid storage chamber 503.

[0074] Optionally, a one-way valve may be provided on the pipeline between the liquid discharge interface 509 and the mixing device 4 to prevent the residual mixed liquid in the mixing device 4 from being sucked into the liquid storage chamber 503 when negative pressure is generated in the liquid storage chamber 503 .

[0075] Optionally, 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, and 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.

[0076] 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 4. 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.

[0077] In one embodiment, the mixing device 4 includes a housing 401, the mixing device 4, and a foam nozzle 402. The interior of the housing 401 is connected to a liquid discharge port 509 and a water discharge port 506. The mixing assembly is disposed within the housing 401. The foam nozzle 402 is connected to the interior of the housing 401 and is adapted to spray the water and foaming agent within the housing 401.

[0078] 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 401 to improve the foaming effect during the foaming process.

[0079] In this embodiment, by integrating the box body 401 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.

[0080] 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.

[0081] 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.

[0082] 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 reduce material costs.

[0083] According to an embodiment of the present application, another aspect of a smart toilet control method is provided, comprising obtaining a first control instruction and controlling a water channel switching member 3 to open a second water outlet 303, a water pump 2, and a mixing device 4 according to the first control instruction; wherein the first control instruction is issued by a control terminal.

[0084] Obtain a second control instruction. According to the second control instruction, the water channel switching component 3 is controlled to open the first water outlet 302 and the water pump 2 is controlled to be turned on. The second control instruction is issued by the control terminal.

[0085] In this embodiment, the flushing device and foaming assembly share the same pump 2, switching between flushing and foaming functions as needed. This maximizes the use of existing components and reduces manufacturing costs. Independent control of the flushing and foaming modes ensures instantaneous response to both the flushing action and the foam shield, preventing mutual interference and optimizing the user experience. In foaming mode, pump 2 forces water supply, ensuring that the pumping device 5 can continue to operate even without tap water pressure, ensuring a zero-water-pressure process.
