Description

Technical Field

[0001] This application relates to the field of bathroom technology, specifically to atomizing devices and smart toilets. Background Technology

[0002] The hygiene and cleaning functions of smart toilets are receiving increasing attention, with atomization sterilization technology being a key component. This technology typically involves spraying a high concentration of electrolyzed water atomized particles onto the inner surface of the toilet bowl to achieve efficient sterilization and disinfection without chemical residue.

[0003] Currently, common smart toilet atomizing sterilization devices typically include an atomizing chamber for generating and storing atomized liquid. This atomizing chamber usually introduces water through a water inlet channel and then performs electrolytic atomization. To discharge un-atomized residual liquid or to clean the chamber, the atomizing chamber is connected to a drainage channel.

[0004] However, the existing structure described above tends to leave a certain amount of electrolyzed water with a high concentration at the bottom of the atomization chamber. This high-concentration residual liquid mixes with the newly injected water during the next atomization cycle. This mixing directly leads to unstable water concentration in the atomization chamber, making precise control impossible and severely affecting the reliability and consistency of the sterilization effect. Utility Model Content

[0005] This application provides an atomizing device and a smart toilet to solve the problem of unstable water concentration in the atomizing chamber, which cannot be accurately controlled and seriously affects the sterilization effect.

[0006] In a first aspect, this application provides an atomizing device, comprising:

[0007] The atomizing chamber includes a first end and a second end opposite to each other, with the second end being higher than the first end. The first end of the atomizing chamber is provided with a water inlet, and the second end of the atomizing chamber is provided with a water outlet.

[0008] The water inlet assembly includes a water volume control unit and a water supply unit, wherein the water volume control unit is connected to the water supply unit and the water inlet is connected to the water inlet hole;

[0009] A drainage component is connected to the water outlet.

[0010] Beneficial effects: By setting a water outlet at the higher second end of the atomizing chamber, gravity allows excess water to be discharged when the water level in the atomizing chamber is higher than the outlet, ensuring consistent water volume and thus consistent atomization volume each time, improving atomization stability. Residual liquid discharge is achieved using the height difference of the chamber and gravity, requiring no additional power or complex control, resulting in a simple structure and high reliability. Placing the water inlet at the lower first end of the atomizing chamber allows water to enter from the bottom, directly collecting and mixing with the high-concentration electrolyte remaining at the bottom of the atomizing chamber, diluting its concentration. With continuous water supply, water continues to be discharged from the connecting pipe for a period of time, thus removing the high-concentration electrolyte remaining at the bottom of the atomizing chamber and ensuring the stability of the atomized water concentration. The water volume control unit precisely controls the water intake each time, ensuring consistent atomized water concentration within the atomizing chamber. The drainage assembly can discharge water from the outlet, eliminating the need for traditional drain valves / pumps, reducing the number of parts, lowering the failure rate, and reducing manufacturing costs.

[0011] In one alternative implementation, it includes:

[0012] The drainage chamber includes a first end and a second end opposite to each other, with the second end being higher than the first end. The water outlet connects the second end of the atomizing chamber and the second end of the drainage chamber. The first end of the drainage chamber is provided with a drainage hole, which is connected to the drainage assembly.

[0013] Beneficial effects: The high-low design of the drain chamber allows residual electrolyzed water entering the drain chamber to naturally converge to the lower drain hole under gravity and be discharged. The connection between the drain chamber and the drain assembly allows water in the drain chamber to be discharged through the flushing assembly, eliminating the need for a traditional drain valve / pump, reducing the number of components, lowering the failure rate, and reducing manufacturing costs. The atomizing chamber and drain chamber are located within the outer casing.

[0014] In one optional implementation, the water volume control unit includes:

[0015] The water distribution valve includes an inlet end, a first outlet end, and a second outlet end. The orifice diameters of the first outlet end and the second outlet end of the water distribution valve are set in a proportional manner. The inlet end of the water distribution valve is connected to the water supply unit. The first outlet end of the water distribution valve is used to connect to the water tank of the toilet. The inlet hole is connected to the second outlet end of the water distribution valve.

[0016] Beneficial effects: By using a water distribution valve to allocate water to the toilet tank and the atomizing chamber inlet in a fixed ratio, a quantitative water supply is achieved. Each time the tank is refilled, the atomizing chamber also receives a fixed amount of water, ensuring consistent water volume each time. Specifically, quantitative water supply is achieved through a fixed orifice ratio, eliminating the need for complex electronic controls or sensors, resulting in a simple structure, low cost, and high reliability. The atomizing chamber water intake is synchronized with the toilet tank refill, simplifying the water supply logic.

[0017] In one optional embodiment, the water volume control unit further includes:

[0018] The first control module is adapted to control the opening and closing of the inlet end of the water distribution valve according to the water level changes in the water tank.

[0019] Beneficial effects: The first control module controls the opening and closing of the water distribution valve according to the water level change in the water tank, ensuring that water enters the atomizing chamber only when the toilet tank needs to be replenished, and is set to only perform atomization when the toilet tank is full, avoiding simultaneous water entry and atomization, which would reduce the atomization concentration.

[0020] In one optional embodiment, the water volume control unit further includes:

[0021] The solenoid valve includes an inlet end and an outlet end, wherein the inlet end of the solenoid valve is connected to the water supply unit, and the inlet hole is connected to the outlet end of the solenoid valve.

[0022] The second control module is electrically connected to the solenoid valve, and the second control module is adapted to control the water outlet duration of the solenoid valve.

[0023] Beneficial effects: The second control module precisely controls the opening and water output duration of the solenoid valve, directly and accurately controlling the amount of water injected into the atomizing chamber, ensuring consistent water intake each time. Water intake into the atomizing chamber is not limited by the toilet tank's water replenishment needs; it can be replenished independently and flexibly according to the requirements of the atomization sterilization program.

[0024] In one optional embodiment, the water volume control unit further includes:

[0025] The switching valve body is connected to at least a first channel and a second channel respectively. The first channel is connected to the water inlet, the second channel is connected to the lower end of the toilet tank, and the water supply unit is connected to the toilet tank.

[0026] The switching valve body is adapted to block the second channel.

[0027] Beneficial effects: Through the water replenishment structure of the toilet tank, when the water level in the toilet tank rises, the water in the tank can enter the switching valve body through the second channel, and then enter the atomizing chamber through the first channel, thereby realizing the replenishment of the atomizing chamber.

[0028] In one optional embodiment, the switching valve body includes:

[0029] The housing includes a first chamber and a second chamber that are interconnected, and both the first channel and the second channel are connected to the first chamber.

[0030] A sealing element is slidably disposed between the first chamber and the second chamber; the end faces of both ends of the sealing element form cavities with the inner walls of the first chamber and the second chamber, respectively.

[0031] The sealing element is adapted to block the second channel.

[0032] Beneficial effects: The cavity design at both ends of the sealing component, combined with the water pressure difference, can drive the sealing component to slide automatically, realizing the opening and closing of the second channel. No additional motor or electromagnetic drive is required, which is energy-saving and reliable.

[0033] In one optional embodiment, the second chamber gradually narrows along the direction from the first chamber to the second chamber, and the first chamber gradually narrows along the direction from the second chamber to the first chamber; the two ends of the sealing member along the direction from the first chamber to the second chamber are respectively adapted to the inner walls of the first chamber and the second chamber.

[0034] Beneficial effects: The sealing element slides within the converging first and second chambers. When water pressure is applied to one end of the sealing element, its tapered end face fits tightly against the inner wall of the converging chamber, forming a reliable seal and effectively blocking the second channel.

[0035] In one optional embodiment, the second chamber is connected to a third channel and a fourth channel, the third channel being connected to the upper end of the toilet tank and the fourth channel being connected to the lower end of the tank. A one-way valve is provided in the fourth channel, and the one-way valve is adapted to connect the second chamber and the tank in the direction from the second chamber to the tank.

[0036] Beneficial effects: Connecting the second chamber to the top of the toilet tank via the third channel allows water to flow from the tank into the second chamber when the water level reaches the connection point. This water then pushes the sealing element to block the second channel, stopping its water supply. As the water level drops, water from the second chamber flows into the tank through the fourth channel, while water from the first chamber flows into the tank through the second channel. A one-way valve in the fourth channel ensures unidirectional drainage, preventing water from entering the second chamber through the fourth channel during water intake. This prevents the sealing element from moving towards the first chamber and blocking the second channel, thus ensuring its water supply.

[0037] In one alternative implementation, it further includes:

[0038] The third control module is electrically connected to the water inlet component, and the third control module is adapted to control the water inlet component to replenish water after atomization.

[0039] Beneficial effect: The third control module controls the water inlet component to replenish water after the atomization device finishes atomization, thereby ensuring the execution of the next atomization.

[0040] Secondly, this application also provides a smart toilet, including an atomizing device.

[0041] Beneficial effects: Integrating a toilet atomizing device into a smart toilet enables the smart toilet to have a stable, efficient, and reliable atomization sterilization function, making the atomization sterilization concentration of the smart toilet more stable, providing more consistent and effective cleaning and sterilization effects, and improving product quality and user satisfaction.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] The following is combined Figures 1 to 10 This describes an embodiment of the present application.

[0057] According to an embodiment of this application, an atomizing device is provided, including an atomizing chamber 1, a water inlet assembly, and a drain assembly. The atomizing chamber 1 includes a first end and a second end opposite to each other, with the second end higher than the first end. The first end of the atomizing chamber 1 is provided with a water inlet 3, and the second end of the atomizing chamber 1 is provided with a water outlet 4. The water inlet assembly includes a water volume control unit and a water supply unit, the water volume control unit being connected to the water supply unit and the water inlet 3. The drain assembly is connected to the water outlet 4.

[0058] It should be noted that placing the water inlet 3 at the lower end of the atomizing chamber 1 allows water to enter from the bottom, directly collecting and mixing with the high-concentration electrolyte remaining at the bottom of the atomizing chamber 1, thus diluting its concentration. With continuous water supply, the water in the atomizing chamber 1 can be continuously discharged from the water outlet 4 for a period of time, thereby removing the high-concentration electrolyte remaining at the bottom of the atomizing chamber 1 and preventing it from remaining there. If the water inlet 3 is placed at other heights in the atomizing chamber 1, as the water level in the atomizing chamber 1 continuously rises until it reaches the water outlet 4, water from the atomizing chamber 1 will continuously enter the water outlet 4. In this case, although the water inlet 3 continuously supplies water for dilution, the water below the water inlet 3 remains undisturbed; only the water above the water inlet 3 is continuously diluted. This results in a limited overall dilution of the atomized water in the atomizing chamber 1, and due to factors such as water pressure and flow rate, the dilution degree cannot be guaranteed, leading to unstable atomization concentration.

[0059] Understandably, water entering from the bottom through the water inlet 3 can sufficiently agitate the atomized water, allowing the water flow control unit to directly control the water flow rate. This ensures consistent dilution of the atomized water within the atomization chamber 1, thereby guaranteeing stable atomization concentration. The water supply unit supplies water to the water flow control unit.

[0060] In this embodiment, by setting a water outlet 4 at the higher second end of the atomizing chamber 1, and utilizing gravity, when the water level in the atomizing chamber 1 is higher than the water outlet 4, the excess water will be discharged from the water outlet 4, ensuring the consistency of the water volume in the atomizing chamber 1, thereby achieving consistent atomization volume each time and improving atomization stability. Residual liquid discharge is achieved using the height difference and gravity, requiring no additional power or complex control, resulting in a simple structure and high reliability. The water volume control unit can precisely control the water intake each time, ensuring the consistency of the atomized water concentration in the atomizing chamber 1. The drainage component can discharge the water discharged from the water outlet 4, eliminating the need for a traditional drain valve / pump, reducing the number of components, lowering the failure rate, and reducing manufacturing costs.

[0061] In one embodiment, a drainage chamber 2 is further included, comprising a first end and a second end opposite to each other, with the second end being higher than the first end. A water outlet 4 connects the second end of the atomizing chamber 1 and the second end of the drainage chamber 2. The first end of the drainage chamber 2 is provided with a drainage hole 12, which is connected to the drainage assembly.

[0062] In this embodiment, the high-low design of the drainage chamber 2 allows residual electrolyzed water entering the drainage chamber 2 to naturally converge to the lower drainage hole 12 under gravity and be discharged. The connection between the drainage chamber 2 and the drainage assembly allows water in the drainage chamber 2 to be discharged through the flushing assembly, eliminating the need for a traditional drain valve / pump, reducing the number of components, lowering the failure rate, and reducing manufacturing costs. The atomizing chamber 1 and the drainage chamber 2 are housed within the outer casing 20.

[0063] In one embodiment, the water volume control unit includes a water distribution valve 5, which includes an inlet end, a first outlet end, and a second outlet end. The orifice diameters of the first outlet end and the second outlet end of the water distribution valve 5 are set in proportion. The inlet end of the water distribution valve 5 is connected to the water supply unit. The first outlet end of the water distribution valve 5 is used to connect to the water tank 6 of the toilet. The inlet hole 3 is connected to the second outlet end of the water distribution valve 5.

[0064] It should be noted that the second water outlet of the water distribution valve 5 is connected to the water inlet 3 through the first water inlet pipe 7. Specifically, the first end of the water inlet 3 is connected to the bottom of the atomizing chamber 1, and the second end of the water inlet 3 can be extended through the external pipe 8 and can be inserted into the drain chamber 2 for easy connection with the first water inlet pipe 7.

[0065] Understandably, the orifice diameters of the first and second water outlets of the water distribution valve 5 are set in proportion, and in conjunction with the quantitative water intake of the water distribution valve 5, quantitative control of the water entering the atomizing chamber 1 can be achieved.

[0066] In this embodiment, the water supply is distributed to the toilet tank 6 and the inlet 3 of the atomizing chamber 1 at a fixed ratio using the water distribution valve 5, achieving quantitative water intake. Each time the tank 6 is refilled, the atomizing chamber 1 also receives a fixed amount of water, ensuring consistent water volume each time. Specifically, quantitative water intake is achieved through a fixed orifice ratio, eliminating the need for complex electronic control or sensors, resulting in a simple structure, low cost, and high reliability. The water intake of the atomizing chamber 1 is synchronized with the refilling of the toilet tank 6, simplifying the water supply logic.

[0067] In one embodiment, a first water inlet method is provided. Specifically, the water volume control unit further includes a first control module adapted to control the opening and closing of the water inlet end of the water distribution valve 5 according to the water level changes in the water tank 6.

[0068] It should be noted that the first control module can control the inlet of the water distribution valve 5. Specifically, the inlet of the water distribution valve 5 can be connected to the water pump, thereby controlling the on / off state of the water pump, which is a component in the water supply unit. The first control module can also be directly electrically connected to the water pump. During atomization, the water pump is in a shut-off state even if there is no water in the water tank 6.

[0069] In this embodiment, the first control module controls the opening and closing of the water distribution valve 5 according to the water level change of the water tank 6, ensuring that the water entering the atomizing chamber 1 only occurs when the toilet tank 6 needs to be replenished, and setting it to only perform atomization when the toilet tank 6 is full, so as to avoid water entering and atomization occurring at the same time, which would lead to a decrease in atomization concentration.

[0070] In one embodiment, a second water inlet method is provided. Specifically, the water volume control unit also includes a solenoid valve 9 and a second control module.

[0071] The solenoid valve 9 includes an inlet end and an outlet end. The inlet end of the solenoid valve 9 is connected to the water supply unit, and the inlet hole 3 is connected to the outlet end of the solenoid valve 9. The second control module is electrically connected to the solenoid valve 9 and is adapted to control the water outlet duration of the solenoid valve 9.

[0072] It should be noted that the water supply unit can be configured with a water pump and an external water source. The water pump supplies water to the inlet of the solenoid valve 9. The solenoid valve 9 is controlled by the second control module, and the water inflow is controlled by time to ensure that the water inflow exceeds the outlet 4. The outlet of the solenoid valve 9 is connected to the inlet 3 through the second inlet pipe 10. Specifically, the first end of the inlet 3 is connected to the bottom of the atomizing chamber 1, and the second end of the inlet 3 can be extended through the external pipe 8 to reach into the drain chamber 2 for easy connection with the second inlet pipe 10.

[0073] In this embodiment, the second control module precisely controls the opening duration of the solenoid valve 9, directly and accurately controlling the amount of water injected into the atomizing chamber 1 to ensure consistent water intake each time. The water intake of the atomizing chamber 1 is not limited by the water replenishment needs of the toilet tank 6, and can be replenished independently and flexibly according to the requirements of the atomization sterilization program.

[0074] In one embodiment, a third water inlet method is provided. Specifically, the water volume control unit also includes a switching valve body 11, which is connected to at least a first channel 1101 and a second channel 1102 respectively. The first channel 1101 is connected to the water inlet 3, the second channel 1102 is connected to the lower end of the toilet tank 6, and the water supply unit is connected to the toilet tank 6.

[0075] The switching valve body 11 is suitable for blocking the second channel 1102.

[0076] Understandably, the water supply unit consists of a water pump, an external water source, and related components used to supply water to the water tank. The first channel 1101 is connected to the water inlet 3 via a pipe, and the connection end of the pipe to the first channel 1101 is located above the atomizing chamber 1.

[0077] In this embodiment, through the water replenishment structure of the toilet tank 6, when the toilet tank 6 is replenished, as the water level in the toilet tank 6 rises, the water in the tank 6 can enter the switching valve body 11 through the second channel 1102, and then enter the atomizing chamber 1 through the first channel 1101, thereby realizing the replenishment of the atomizing chamber 1.

[0078] In one embodiment, the switching valve body 11 includes a housing 1103 and a sealing member 1104. The housing 1103 includes a first chamber 1105 and a second chamber 1106 that are interconnected, and a first channel 1101 and a second channel 1102 are both connected to the first chamber 1105. The sealing member 1104 is slidably disposed between the first chamber 1105 and the second chamber 1106; the end faces at both ends of the sealing member 1104 form cavities with the inner walls of the first chamber 1105 and the second chamber 1106, respectively. The sealing member 1104 is adapted to block the second channel 1102.

[0079] In this embodiment, the cavity design at both ends of the sealing member 1104, combined with the water pressure difference, can drive the sealing member 1104 to slide automatically, realizing the opening and closing of the second channel 1102 without the need for an additional motor or electromagnetic drive, which is energy-saving and reliable.

[0080] In one embodiment, the second chamber 1106 gradually narrows along the direction from the first chamber 1105 to the second chamber 1106, and the first chamber 1105 gradually narrows along the direction from the second chamber 1106 to the first chamber 1105; the two ends of the sealing member 1104 along the direction from the first chamber 1105 to the second chamber 1106 are respectively adapted to the inner walls of the first chamber 1105 and the second chamber 1106.

[0081] It should be noted that the taper of the two ends of the sealing member 1104 is the same as that of the first chamber 1105 and the second chamber 1106, respectively. However, when the sealing member 1104 is in a free state, there is a gap between its outer wall and the inner walls of the two chambers. When the sealing member 1104 moves left and right under the influence of the water pressure on both sides, it can fit against the inner walls of the two chambers respectively. When the sealing member 1104 is in a free state, the second channel 1102 is in an open state.

[0082] In this embodiment, the sealing member 1104 slides within the converging first chamber 1105 and second chamber 1106. When water pressure is applied to one end of the sealing member 1104, its conical end face fits tightly against the inner wall of the converging chamber, forming a reliable seal and effectively blocking the second channel 1102.

[0083] In one embodiment, the second chamber 1106 is connected to a third channel 1107 and a fourth channel 1108. The third channel 1107 is connected to the upper end of the toilet tank 6, and the fourth channel 1108 is connected to the lower end of the tank 6. A one-way valve 1109 is provided in the fourth channel 1108. The one-way valve 1109 is adapted to connect the second chamber 1106 and the tank 6 in the direction from the second chamber 1106 to the tank 6.

[0084] In this embodiment, the second chamber 1106 is connected to the upper end of the toilet tank 6 via the third channel 1107. This allows water in the tank 6 to enter the second chamber 1106 through the third channel 1107 when the water level in the tank reaches the connection point between the third channel 1107 and the upper end of the toilet tank 6. This water then pushes the sealing member 1104 to block the second channel 1102, thus stopping the water supply from the second channel 1102. When the water level in the tank 6 drops, water in the second chamber 1106 enters the tank 6 through the fourth channel 1108, while water in the first chamber 1105 enters the tank 6 through the second channel 1102. A one-way valve 1109 is installed in the fourth channel 1108 to enable one-way drainage. This prevents water in the water tank 6 from entering the second chamber 1106 through the fourth channel 1108 during water intake, which would push the sealing component 1104 towards the first chamber 1105, causing blockage of the second channel 1102 and affecting the water supply effect of the second channel 1102.

[0085] In one embodiment, a first drainage method is provided. Specifically, the drainage component includes a flushing pipe 13 connected to a water trap, and the flushing pipe 13 is connected to a drain hole 12. The drain hole 4 is higher than the water surface inside the water trap.

[0086] In this embodiment, the flushing pipe 13 is connected to the trap. With the drain hole 12 connected to the flushing pipe 13 via the first connecting pipe 15, the connection between the drain hole 12 and the trap is achieved. Since when the water level in the trap is higher than the water surface, water exceeding the water surface will enter the drain pipe. Therefore, the outlet hole 4 is positioned higher than the water surface. When the water level flowing from the outlet hole 4 into the drain chamber 2 is above the water surface, the water in the drain chamber 2 will, under its own gravity, enter the trap through the flushing pipe 13 for discharge. The entire drainage process is real-time, ensuring that the water level in the drain chamber 2 remains below the outlet hole 4, thus preventing backflow.

[0087] In one embodiment, a second drainage method is provided. Specifically, the drainage component includes a water tank 6, which includes a water inlet and a water outlet. The water inlet of the water tank 6 is connected to an external water source, and the water outlet of the water tank 6 is connected to a water trap. The water tank 6 is also connected to a drain hole 12. The drain hole 12 is higher than the lowest water level in the water tank 6, and the connection point between the water tank 6 and the drain hole 12 is lower than the drain hole 12.

[0088] Understandably, the lowest water level in water tank 6 is the remaining water level in water tank 6 after flushing and before refilling.

[0089] It should be noted that the drain hole 12 is connected to the water tank 6 through the second connecting pipe 16, and the second connecting pipe 16 gradually slopes downward along the direction from the drain hole 12 to the water tank 6, which can ensure that the water flowing out of the drain hole 12 can smoothly enter the water tank 6 and avoid water accumulation in the second connecting pipe 16.

[0090] In this embodiment, when the water tank 6 is flushed, the water level inside the tank drops, exposing the connection point between the drain hole 12 and the water tank 6. Since the connection point between the water tank 6 and the drain hole 12 is lower than the drain hole 12, the water in the drain chamber 2 will be forced into the water tank 6 under atmospheric pressure and then discharged into the ceramic drain pipe.

[0091] In one embodiment, a third drainage method is provided. Specifically, the drainage component includes a water tank 6 and a water pump 14. The water pump 14 includes an inlet end and an outlet end. The outlet end of the water pump 14 is connected to a water trap, and the inlet end of the water pump 14 is connected to the drain hole 12 and the water tank 6 respectively.

[0092] It should be noted that the water inlet of the water pump 14 is connected to the bottom of the water tank 6 through the water pump pipe 17, and the drain hole 12 is connected to the water pump pipe 17 through the third connecting pipe 18. When the water pump 14 is driven and the water in the water tank 6 is drawn through the water pump pipe 17, the water pump pipe 17 is in a negative pressure state, and the water in the drain chamber 2 can be drawn out and discharged through the third connecting pipe 18.

[0093] In this embodiment, by directly reusing the existing water pump 14 used for flushing the toilet to draw liquid from the drain chamber 2, the water in the drain chamber 2 can be drawn away along with the water in the water tank 6 when the water pump 14 is drawing water for flushing, thus achieving discharge. At the same time, the active suction force provided by the water pump 14 ensures that all water in the drain chamber 2 is discharged.

[0094] In one embodiment, this solution provides three water inlet methods and three drainage methods, which can be combined arbitrarily.

[0095] In one embodiment, a one-way valve 19 is provided at the output end of the drain hole 12.

[0096] In one embodiment, a third control module is further included, electrically connected to the water inlet component, the third control module being adapted to control the water inlet component to replenish water after atomization.

[0097] It should be noted that the first, second, and third control modules are integrated onto a control circuit board, which is a common control component in smart toilets. The atomizer in the atomizing device is electrically connected to the control circuit board.

[0098] Optionally, a first control program is set in the third control module. The first control program can control the atomization time of the atomizer. After the atomizer completes atomization, the third control module controls the water inlet component to replenish water into the atomization chamber 1.

[0099] Optionally, a water level sensing element, i.e. a water level sensor, can be installed inside the atomizing chamber 1. The water level sensing element can transmit the water level signal to the third control module in real time. When the third control module senses that the water level has dropped and stabilized for a period of time, it determines that atomization has ended and then controls the water inlet component to replenish water into the atomizing chamber 1.

[0100] Optionally, when the water level sensing element detects a drop in water level, the third control module needs to control the water inlet component to delay water intake until the atomization is determined to be finished. This can prevent the situation of water intake and atomization occurring simultaneously, which would lead to a decrease in atomization concentration.

[0101] Specifically, in the first water inlet method, a first flushing program can also be set, and the third control module can be electrically connected to the water distribution valve 5. After atomization, the first flushing program first controls the smart toilet to flush, discharging the water in the water tank 6. After flushing, the third control module can control the water distribution valve 5 to replenish water to the atomization chamber 1 and the water tank 6, ensuring that the amount of water replenished to the atomization chamber 1 each time is constant, and the water in the atomization chamber 1 can enter the drain chamber 2 through the water outlet 4.

[0102] In the second water inlet method, the third control module can be electrically connected to the solenoid valve 9. After atomization, the third control module can control the solenoid valve 9 to replenish water into the atomization chamber 1, and ensure that the amount of water replenished into the atomization chamber 1 each time is constant, and the water in the atomization chamber 1 can enter the drainage chamber 2 through the water outlet 4.

[0103] In the third water inlet method, a second flushing program can also be set. After the atomization is completed, the second flushing program first controls the smart toilet to flush, draining the water in the water tank 6. After flushing, the water tank 6 is replenished. By switching the valve body 11, it is ensured that the amount of water replenished into the atomization chamber 1 each time is constant, and the water in the atomization chamber 1 can enter the drain chamber 2 through the water outlet 4.

[0104] In this embodiment, the water inlet component is controlled by the third control module to replenish water after the atomizing device finishes atomizing, thereby ensuring the execution of the next atomization.

[0105] In one embodiment, an anti-dry-burning component is also provided, and a temperature monitoring module is provided in the atomizer. The temperature monitoring module is electrically connected to the control circuit board and is suitable for monitoring the temperature of the atomizing plate in the atomizer. When an abnormal rise in the temperature of the atomizing plate is detected, the atomization control module in the control circuit board can control the atomizer to stop atomizing, or the control circuit board can control the water inlet component to replenish water into the atomization chamber 1.

[0106] According to an embodiment of this application, another aspect provides a smart toilet, including an atomizing device.

[0107] In this embodiment, the atomizing device is integrated into the smart toilet, enabling the smart toilet to have a stable, efficient, and reliable atomizing sterilization function. This makes the atomizing sterilization concentration of the smart toilet more stable, providing a more consistent and effective cleaning and sterilization effect, thereby improving product quality and user satisfaction.

[0108] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
