Description

Technical Field

[0001] The present invention relates to the technical field of intelligent toilets, and in particular to an air pump booster pulse cleaning device and an intelligent toilet. Background Art

[0002] In modern home life, smart toilets are increasingly becoming a key choice for people pursuing a high-quality lifestyle due to their convenience and comfort. The buttocks cleaning function of smart toilets has become a core requirement for improving user health and comfort. However, balancing the gentleness of the water flow and cleaning power to meet the needs of different users remains a technical challenge.

[0003] Although existing cleaning devices can achieve basic cleaning through air-water mixing, they generally have two core defects: first, the air-water mixing ratio is fixed, resulting in the water flow texture being either too strong and stinging the anal mucosa due to insufficient bubble content, or the cleaning power being weakened due to excessive bubbles; second, the flushing water pressure is constant, making it difficult to take into account both daily care and deep cleaning needs.

[0004] Current technology uses a fixed power level for conventional air pumps, and the simple air-liquid mixing chamber only allows for mechanical mixing of coarse bubbles (>1mm in diameter) with the water flow, which can cause a slight stinging sensation. This is particularly problematic for women undergoing menstrual care, those with anorectal conditions, or the health of the elderly. Therefore, improving the hip-washing experience of smart toilets to accommodate a wider range of user needs is a pressing challenge.

[0005] It should be noted that the information disclosed in this background technology section is only intended to increase understanding of the overall background of the present invention, and should not be regarded as an admission or any form of implication that the information constitutes prior art already known to those skilled in the art. Summary of the Invention

[0006] In order to solve the technical problems existing in the buttocks cleaning device of the above-mentioned existing intelligent toilet during the buttocks washing process, the present invention provides an air pump boost pulse cleaning device, which at least includes: Air pump, used to continuously generate compressed air; An air storage and pressurizing component, comprising a sealed cavity and an air inlet and an air outlet connected to the sealed cavity, wherein the air inlet is connected to the air pump, and the air pump outputs compressed air to the sealed cavity when in operation; a pulse control valve connected to the air outlet and configured to periodically open and close to release the compressed air in the closed chamber; A water-gas mixing element having a water-gas mixing chamber and an air inlet, a water inlet, and a water outlet connected to the water-gas mixing chamber; The compressed air in the closed cavity enters the water-gas mixing cavity from the air inlet through the opening of the pulse control valve and mixes with the water flow delivered by the water inlet to form a water-gas mixture. The pulse control valve is periodically opened or closed, and the water flow out of the water outlet presents a pulse characteristic.

[0007] Furthermore, the air storage booster also includes a pressure-changing assembly located in the closed cavity to drive the compressed air in the closed cavity to be pressurized; the pressure-changing assembly includes a push rod, a seal and a compression spring, the push rod is movably arranged in the closed cavity, and forms a sealed connection with the inner wall of the closed cavity through the seal, so that a variable compression space is formed in the closed cavity; the variable compression space is connected to the air inlet and the air outlet; the compression spring abuts between the push rod and the closed cavity, when compressed air enters the variable compression space from the air inlet, the push rod compresses the compression spring under the action of the compressed air, and when the pulse control valve is opened, the rebound force of the compression spring causes the push rod to pressurize the compressed air in the variable compression space and enter the water-gas mixing element through the pulse control valve.

[0008] Furthermore, the water-gas mixing chamber is provided with a porous structural member near the water outlet, and / or the water outlet is provided with a porous structural member, so that the water-gas mixture is cut by the porous structural member to form fine bubbles.

[0009] Furthermore, the water-gas mixing element further includes a check element, which is provided between the air inlet and the water-gas mixing chamber and is used to allow the compressed air to flow into the water-gas mixing chamber from the air inlet in one direction only, preventing it from flowing in the reverse direction.

[0010] Furthermore, the water-gas mixing element also includes an inlet cavity, a conducting hole, and a limiting hole arranged between the air inlet and the water-gas mixing chamber. The inlet cavity is located on the side close to the air inlet and is connected to the air inlet. The conducting holes respectively connect the inlet cavity and the water-gas mixing chamber to allow compressed air to pass through. The check element passes through the limiting hole from the inlet cavity and extends to the bottom of the water-gas mixing chamber to form an umbrella shape; there are multiple conducting holes, and the sum of the cross-sectional areas of the conducting holes is smaller than the cross-sectional area of the inlet cavity.

[0011] The present invention also provides an intelligent toilet, comprising any of the above-mentioned air pump boost pulse cleaning devices.

[0012] Furthermore, it also includes a control component and a music component electrically connected to the control component. When the control component controls the air pump boost pulse cleaning device to execute a cleaning instruction, the air storage boost component triggers a corresponding signal when the compressed air is boosted to one or more preset thresholds, and starts the music component through the signal to play music to cover the cleaning noise and / or perform noise reduction action.

[0013] Furthermore, when the air storage and boosting component includes a pressure-transforming component having a push rod and a compression spring, the compressed air in the closed cavity is pressurized by the push rod and the compression spring; it also includes a travel switch or a push button switch located on the push rod stroke path; when the push rod is pushed to or pushed to a preset position, the travel switch or the push button switch is triggered to generate a signal; wherein, when the push rod is pushed to or pushed to a preset position with a shorter stroke, the trigger signal starts the music component to play music, and / or, when the push rod is pushed to or pushed to a preset position with a longer stroke, the trigger signal performs a strong noise reduction action.

[0014] Furthermore, it also includes a control component and a flushing component electrically connected to the control component. The air storage and boosting component triggers a corresponding signal when the compressed air is pressurized to one or more preset thresholds, and starts the flushing component through the signal to perform single-speed or multi-speed flushing actions.

[0015] Furthermore, when the air storage and boosting component includes a pressure-changing component having at least a push rod and a compression spring, the compressed air in the closed chamber is boosted by the push rod and the compression spring; it also includes a travel switch or a push button switch located on the travel path of the push rod; when the push rod is pushed to or pushed to a preset position, the travel switch or the push button switch is triggered to generate a signal; a pressure sensor is integrated at the top of the push rod, and the pressure sensor is used to collect the pressure value of the push rod in real time; wherein, when the push rod is pushed to or pushed to a first preset position and the pressure value of the push rod is between a first preset threshold value, a pre-flush mode is triggered to moisten the inner wall of the smart toilet; and / or, when the push rod is pushed to or pushed to a second preset position and the pressure value of the push rod is between the first preset threshold value and the second preset threshold value, a standard flushing mode is triggered to flush the inner wall of the smart toilet; and / or, when the push rod is pushed to or pushed to a third preset position and the pressure value of the push rod is greater than the second preset threshold value, a strong flushing mode is triggered to strongly flush the inner wall of the smart toilet.

[0016] Based on the above, the air pump booster pulse cleaning device provided by the present invention, compared with the existing technology, forms a water-gas mixture by mixing air and water flow to effectively improve the comfort of cleaning, and dynamically adjusts the air-water mixing ratio and cleaning intensity by periodically opening or closing the pulse control valve to effectively meet the needs of different users.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof all mean "at least including".

[0022] Example 1 See also Figure 1 、 Figure 2 The present invention provides an air pump boost pulse cleaning device, which includes at least an air pump 10, an air storage and boosting component 20, a pulse control valve 30, and a water-gas mixing component 40.

[0023] The air pump 10, as the air supply component, primarily draws in ambient air and continuously generates compressed air at a certain pressure. Air pump 10 can employ common piston or diaphragm air pumps, though this embodiment prefers a diaphragm air pump, which features stable performance and low cost. The air pump 10 is sealed to the air inlet 23 of the air storage and pressurization component 20 via an air pipe, ensuring smooth air flow into the sealed chamber 21.

[0024] The air storage and booster component 20 has a closed cavity 21 and an air inlet 23 and an air outlet 24 connected to the closed cavity 21. The air inlet 23 is connected to the air pump 10, and the air pump 10 outputs compressed air to the closed cavity 21 when working. In this embodiment, the air storage and booster component 20 also includes a pressure-changing component 22 located in the closed cavity 21. Among them, the pressure-changing component 22 is used to pressurize the air located in the closed cavity 21, thereby further improving the cleaning force of the subsequent water flow out. The pressure-changing component 22 can adopt but is not limited to structures such as a diaphragm compression component, a push rod compression component, a centrifugal compression component, and a piston / cylinder compression component. Taking the diaphragm compression component as an example, the solenoid valve coil can be energized, and the magnet attracts the diaphragm to move to one side of the closed cavity 21, so that the air volume in the closed cavity 21 is reduced, and the compressed air is further compressed to achieve a pressurization effect. For example, a centrifugal compressor uses a miniature centrifugal impeller driven by a motor to force air into the impeller. Centrifugal force then propels the air toward the inner wall of the volute, converting kinetic energy into pressure energy, creating pressurized compressed air. For example, a piston / cylinder compressor uses the reciprocating motion of the piston or cylinder to compress the air and achieve supercharging. Specific settings can be tailored to your needs.

[0025] The pulse control valve 30 is connected to the air outlet 24 and is configured to periodically open and close to release the compressed air within the sealed chamber. The pulse control valve 30 can periodically open and close according to a preset pulse signal. When the pulse control valve 30 is open, the compressed air within the sealed chamber 21 enters the pulse control valve 30 through the air outlet 24 and further flows to the water-air mixing element 40. When the pulse control valve 30 is closed, the flow of compressed air is blocked.

[0026] The water-gas mixing element 40 has a water-gas mixing chamber 41 and an air inlet 42, a water inlet 43, and a water outlet 44 connected to the water-gas mixing chamber 41; the air inlet 42 is connected to the pulse control valve 30; and the water inlet 43 is connected to an external water source (such as a tap water pipeline) through a water pipe. The water-gas mixing chamber 41 is used to fully mix the incoming compressed air and water flow to form a water-gas mixture. Some flow-disturbing structures, such as spoilers, spiral blades, etc., can be provided in the water-gas mixing chamber 41 to enhance the air-water mixing effect. Preferably, the water-gas mixing element 40 also includes a check element 60, which is provided between the air inlet 42 and the water-gas mixing chamber 41 and is used to allow the compressed air to flow into the water-gas mixing chamber 41 in a one-way direction only from the air inlet 42, preventing it from flowing in the opposite direction. The check element 60 may be, for example, a one-way valve to allow compressed air to enter the water-gas mixing chamber 41 only from the air inlet 42 and not to return from the water-gas mixing chamber 41 to the air inlet 42 , thereby ensuring unidirectional flow of the air path.

[0027] See also Figure 3During pulse cleaning, the air pump 10 outputs air into the sealed chamber 21. The compressed air within the sealed chamber 21 enters the water-air mixing chamber through the air inlet 42 when the pulse control valve 30 is opened, where it mixes with the water delivered by the water inlet 43 to form a water-air mixture. The pulse control valve periodically opens and closes, causing the water flowing out of the water outlet to exhibit a pulsed characteristic. The pulse control valve 30 periodically opens and closes according to a preset pulse signal to control the water-air mixture to flow out of the water outlet 44.

[0028] Preferably, the duration that the air pump 10 outputs air to fill the sealed chamber 21 and the duration that the pulse control valve 30 is closed vary dynamically within the pulse cleaning cycle. Specifically, the air pump 10 can control the time it takes for the sealed chamber 21 to be filled with gas by adjusting the duty cycle of the input voltage. The greater the duty cycle, the faster the air pump 10 operates, the faster air is input into the sealed chamber 21, and the shorter the duration that the air pump 10 outputs air to fill the sealed chamber 21. Therefore, assuming that the duration that the air pump 10 outputs air to fill the sealed chamber 21 is T1, and the duration that the pulse control valve 30 is closed is T2, when T1 < T2, the sealed chamber 21 is filled with the most gas. When the pulse control valve 30 is open, the sealed chamber 21 inputs the maximum amount of compressed air (also at the maximum pressure) into the water-gas mixing chamber 41. At this time, the maximum amount of gas mixes with water to form the strongest water-gas mixture. When the pulse control valve 30 is closed, there is no gas in the water-gas mixing chamber 41, only pure water. The water-gas mixture at this point is equivalent to a pulse of water. When T1 > T2, the sealed chamber 21 inputs a submaximal volume of compressed air (and therefore submaximal pressure) into the water-gas mixing chamber 41, resulting in a relatively weak water-gas mixture.

[0029] Based on the above principle, by controlling the time it takes for the air pump 10 to output air to fill the closed chamber 21 and the closing time of the pulse control valve 30 to change dynamically during the pulse cleaning cycle, the volume and pressure of the compressed air in the closed chamber 21 can be controlled to provide users with different cleaning intensity experiences. In this dynamic change process, not only can the air-water mixing ratio be changed, so that the water flow texture takes into account both cleaning power and water flow gentleness; the flushing water pressure can also be gradually changed, which can effectively take into account the needs of daily care and deep cleaning. It should be noted that the specific dynamic change process of the time it takes for the air pump 10 to output air to fill the closed chamber 21 and the closing time of the pulse control valve 30 can be reasonably designed according to actual needs, and its specific change examples all fall within the scope of protection of the present invention.

[0030] Further, see Figure 2, the water-gas mixing chamber 41 is provided with a porous structural member 50 near the water outlet 44, and / or, the water outlet 44 is provided with a porous structural member 50, so that the water-gas mixture is cut by the porous structural member 50 to form fine bubbles. Among them, the porous structural member 50 can be a plate-like structure with many small holes, and the material can be selected from materials with a certain strength such as stainless steel and ceramics. For example, this embodiment adopts a porous plate with a stainless steel middle part and a silica gel edge, and circular holes with a diameter of 0.5-2 mm are evenly distributed on its surface. The hole spacing is designed according to actual needs, generally about 1-3 mm.

[0031] After the water-gas mixture is formed in the water-gas mixing chamber 41, it will pass through the porous structural member 50 when flowing toward the water outlet 44. Since the holes on the porous structural member 50 are relatively small, the water-gas mixture will be divided into multiple small water streams and air columns when passing through these holes. In this process, the gas-liquid interface changes dramatically, and the originally larger bubbles will be cut into many small bubbles, making the bubbles in the water-gas mixture smaller, denser and more evenly distributed. Small bubbles have a larger specific surface area and higher surface activity. During the cleaning process, they can better adhere to the surface of the cleaned part, such as the wrinkles of the skin on the human buttocks. When the bubbles burst, a small impact force is generated, which helps to remove dirt and bacteria and improve the thoroughness of cleaning.

[0032] Furthermore, if the porous structural member 50 is positioned near the air inlet 42, the air is first cut and then mixed with water, resulting in larger bubbles and a greater risk of stinging. Therefore, in this embodiment, the porous structural member 50 is preferably positioned near the water outlet 44 in the water-air mixing chamber 41, so that the water-air mixture is cut at the outlet 44. This results in denser bubbles and a better cleaning experience.

[0033] Furthermore, in this embodiment, porous structural members 50 are preferably provided at both the water outlet 44 and the water outlet 44 of the water-gas mixing chamber 41. When porous structural members 50 are provided at both the water outlet 44 and the water outlet 44 of the water-gas mixing chamber 41, the water-gas mixture will undergo two refinement processes. First, the first cutting and refinement is performed at the porous structural member 50 near the water outlet 44 of the water-gas mixing chamber 41 to initially form smaller bubbles and more dispersed water flows. Then, these preliminarily treated water-gas mixtures are further refined and segmented through the porous structural member 50 at the water outlet 44, so that the bubbles in the finally ejected water-gas mixture are smaller and more uniform, thereby improving the cleaning effect.

[0034] Optionally, see Figure 5 、 Figure 6The water-gas mixing element 40 also includes an inlet chamber 45, a conducting hole 46, and a limiting hole 47 provided between the air inlet 42 and the water-gas mixing chamber 41. The inlet chamber 45 is located on the side close to the air inlet 42 and is connected to the air inlet 42. The conducting hole 46 connects the inlet chamber 45 and the water-gas mixing chamber 41 respectively to allow compressed air to pass through. The check element 60 extends from the inlet chamber 45 through the limiting hole 47 and toward the bottom of the water-gas mixing chamber 41 to form an umbrella shape. There are multiple conducting holes 46, and the sum of the cross-sectional areas of the conducting holes 46 is smaller than the cross-sectional area of the inlet chamber 45.

[0035] The inlet chamber 45 is a cylindrical cavity located on the side of the water-gas mixing element 40 near the air inlet 42. It temporarily stores compressed air to stabilize the airflow. The guide holes 46 are evenly distributed circular holes arranged in a ring-shaped array. In this embodiment, the cross-sectional area of the inlet chamber 45 is greater than the sum of the cross-sectional areas of the guide holes 46. This arrangement allows compressed air to enter the inlet chamber 45 at high speed from the air inlet 42. The expanded space reduces the flow velocity (Bernoulli's principle), converting kinetic energy into static pressure energy. Upon passing through the guide holes 46, the airflow accelerates due to the sudden decrease in cross-sectional area, forming a high-speed jet that is injected into the water-gas mixing chamber 41. This enhances the shear effect between the gas and liquid, effectively creating a "diffusion-throttling" effect and further thoroughly mixing the compressed air and water. The cross-sectional area refers to the cross-sectional area perpendicular to the direction of compressed air flow.

[0036] In this embodiment, the check element 60 preferably extends from the inlet chamber 45 through the stop hole 47 toward the bottom of the water-gas mixing chamber 41 to form an umbrella-shaped valve flap structure, wherein the umbrella cover at least covers the end of the guide hole 46. The umbrella handle is provided with a positioning portion on the side of the stop hole 47 near the inlet chamber 45. The positioning portion is used to prevent the umbrella-shaped valve flap structure from being pushed into the water-gas mixing chamber 41 by compressed air and thus losing its one-way flow function. Of course, the stop hole 47 can also be configured as a stepped hole to cooperate with the stepped umbrella handle for effective positioning.

[0037] In this embodiment, the umbrella-shaped valve flap structure is preferably made of silicone material to provide a certain strength while also being flexible. When the pulse control valve 30 is opened, compressed air enters the guide hole 46 from the inlet chamber 45 and impacts the umbrella surface, causing the umbrella surface to open toward the water-vapor mixing chamber 41.

[0038] In this example, see Figure 4The pressure-variable assembly 22 includes a push rod 22a, a seal 22b, and a compression spring 22c. The push rod 22a is movably disposed within the sealed chamber 21 and forms a sealed connection with the inner wall of the sealed chamber 21 via the seal 22b, thereby forming a variable compression space 21a within the sealed chamber 21. The variable compression space 21a communicates with the air inlet 23 and the air outlet 24. The seal 22b is an O-ring that is installed in an annular groove on the inner wall of the sealed chamber 21 or in an annular groove on the outer diameter of the push rod 22a, thereby forming a dynamic seal in the sealed chamber 21 when the push rod 22a reciprocates.

[0039] The compression spring 22c is in contact between the push rod 22a and the sealed cavity 21. Figure 4 As shown, one end of the compression spring 22c abuts against the boss on the push rod 22a that contacts the variable compression space 21a, and the other end of the compression spring 22c abuts against the bottom of the closed chamber 21. Preferably, a positioning groove is provided at the bottom of the closed chamber 21, and the compression spring 22c abuts against the positioning groove to prevent the compression spring 22c from being subjected to eccentric force.

[0040] When compressed air enters the variable compression space 21a from the air inlet 23, the push rod 22a compresses the compression spring 22c under the action of the compressed air, and when the pulse control valve 30 is opened, the rebound force of the compression spring 22c causes the push rod 22a to pressurize the compressed air in the variable compression space 21a and enter the water-gas mixing element 40 through the pulse control valve 30.

[0041] In summary, during pulse cleaning, the entire device works according to the following steps: 1. Air compression stage: The air pump 10 starts and continuously outputs compressed air into the sealed chamber 21. After the compressed air enters the variable compression space 21a, it pushes the push rod 22a to compress the compression spring 22c, causing the compressed air to be pressurized in the variable compression space 21a, forming compressed air with a higher pressure.

[0042] 2. Pulse Control Phase: The pulse control valve 30 periodically opens and closes to release the compressed air within the sealed chamber. When the pulse control valve 30 is open, compressed air flows through the pulse control valve 30 from the air inlet 42 into the water-gas mixing chamber 41. When the pulse control valve 30 is closed, the flow of compressed air is blocked.

[0043] 3. Water-Air Mixing Stage: As compressed air enters the water-air mixing chamber 41, water from an external source is delivered into the chamber through the water inlet 43. The compressed air and water mix thoroughly within the chamber 41, forming a water-air mixture. Due to the periodic opening and closing of the pulse control valve 30, the compressed air entering the chamber 41 is pulsed, resulting in a pulsed water-air mixture. Specifically, the water flowing out of the water outlet exhibits a pulsed characteristic.

[0044] 4. Pulse spraying stage: The water flow containing the water-gas mixture is sprayed out from the water outlet 44 with pulse characteristics, and the parts that need to be cleaned are pulse-cleaned.

[0045] Example 2 The present invention also provides an intelligent toilet, comprising the air pump boost pulse cleaning device described in any one of the implementation modes of the above-mentioned embodiment 1.

[0046] In practice, an air pump boost pulse cleaning device is installed in the smart toilet to achieve the buttocks cleaning function. The air pump boost pulse cleaning device is also used to achieve signal linkage with the smart toilet, effectively improving the buttocks cleaning effect and satisfying the cleaning experience of different users.

[0047] It should be noted that the specific structure, function and effect of the air pump boost pulse cleaning device can be referred to above, and will not be described in detail in this embodiment.

[0048] Furthermore, the smart toilet also includes at least a toilet body, a control component, a music component, a flushing component, etc. Preferably, please refer to Figure 7 The air pump boost pulse cleaning device is electrically connected to the control component for transmitting or feedback signals. The control component is electrically connected to the flushing component and the music component respectively for controlling the flushing component and the music component to perform corresponding actions according to the signals fed back by the air pump boost pulse cleaning device, so as to achieve good noise processing effect and realize refined control of the flushing function of the intelligent toilet.

[0049] In a preferred embodiment, the intelligent toilet includes a control component and a music component electrically connected to the control component. The specific circuit design can be tailored to actual needs and combined with existing conventional technologies, and will not be detailed in this embodiment. Furthermore, the air storage and boosting component 20 triggers a corresponding signal when the compressed air reaches one or more preset thresholds. This signal activates the music component to play music to cover cleaning noise and / or reduce noise.

[0050] Specifically, a program or structure is designed based on the specific structure of the air storage and boosting component 20 to sense the compressed air pressurization to one or more preset thresholds, which are used to trigger a corresponding signal. The preset threshold should reflect a quantitative value of the compressed air pressurization level, such as a preset pressure value, a preset volume value, a preset position, or a preset time value to which the compressed air in the closed chamber is pressurized, etc. The specific setting can be reasonably determined according to the actual structure and falls within the scope of protection of the present invention. For example, when the air storage and boosting component 20 uses a diaphragm boosting component, the corresponding signal can be triggered based on the power-on time of the solenoid valve coil. For another example, when the air storage and boosting component 20 uses a centrifugal boosting component, the corresponding signal can be triggered based on the drive time of the drive motor. For another example, when the air storage and boosting component 20 uses a piston or cylinder boosting component, the corresponding signal can be triggered based on its boost stroke position or boost volume, thereby effectively covering the noise caused by cleaning and providing the user with a better and more comfortable experience.

[0051] In this embodiment, the gas storage and pressurizing component 20 includes a pressure-changing assembly 22 having at least a push rod 22a and a compression spring 22c, and the compressed air in the closed chamber 21 is pressurized by the push rod 22a and the compression spring 22c. Figure 7 As shown, the apparatus further includes a travel switch or pushbutton switch located along the travel path of the push rod 22a. When the push rod 22a is pushed or pushed to a preset position, the travel switch or pushbutton switch is triggered to generate a signal. When the push rod 22a is pushed or pushed to a preset position with a shorter travel, the signal is triggered to play music, and / or when the push rod 22a is pushed or pushed to a preset position with a longer travel, the signal is triggered to perform a strong noise reduction action. It should be noted that the preset positions of the shorter travel and the longer travel are relative, not specific limits on their travels. When the push rod 22a is in the preset position with a shorter travel, the water-vapor mixture is being cleaned with less force. Therefore, the noise generated by the cleaning process can be masked by controlling the activation of a music component to play music. When the push rod 22a is in the preset position with a longer travel, the water-vapor mixture is being cleaned with greater force. Therefore, a strong noise reduction action can be performed to reduce the noise generated by the cleaning process, such as automatically enhancing low-frequency sound insulation.

[0052] This embodiment utilizes the stroke length of the push rod 22a as a trigger condition, and coordinates the dynamic changes in the time it takes for the air pump 10 in the air pump boost pulse cleaning device to output air to fill the closed chamber 21 and the closing time of the pulse control valve 30 during the pulse cleaning cycle. It can differentially execute background music playback and / or strong noise reduction actions, thereby improving the scene adaptability of the user experience.

[0053] In another preferred embodiment, the smart toilet further includes a control component and a flushing component electrically connected to the control component. The specific circuit design can be reasonably designed based on actual needs and in combination with existing conventional technologies, and will not be described in detail in this embodiment. The air storage and boosting component 20 triggers a corresponding signal when the compressed air is boosted to one or more preset thresholds, and activates the flushing component through the signal to perform a single-speed or multi-speed flushing action. The single-speed or multi-speed smart toilet flushing action can be reasonably designed in combination with the flushing component of the specific smart toilet.

[0054] For example, when the air storage booster 20 includes a pressure-changing assembly 22 having at least a push rod 22a and a compression spring 22c, the compressed air in the closed chamber 21 is pressurized by the push rod 22a and the compression spring 22c; it also includes a travel switch or a push button switch located on the travel path of the push rod 22a; when the push rod 22a is pushed to or pushed to a preset position, the travel switch or the push button switch is triggered to generate a signal; a pressure sensor is integrated at the top of the push rod 22a, and the pressure sensor is used to collect the pressure value of the push rod 22a in real time.

[0055] Among them, when the push rod 22a is pushed to or pushed to the first preset position and the pressure value of the push rod 22a is between the first preset threshold value, the pre-flush mode is triggered to moisten the inner wall of the smart toilet; and / or, when the push rod 22a is pushed to or pushed to the second preset position and the pressure value of the push rod 22a is between the first preset threshold value and the second preset threshold value, the standard flush mode is triggered to flush the inner wall of the smart toilet; and / or, when the push rod 22a is pushed to or pushed to the third preset position and the pressure value of the push rod 22a is greater than the second preset threshold value, the strong flush mode is triggered to strongly flush the inner wall of the smart toilet.

[0056] In the flushing mode settings of the above-mentioned gears, the stroke of the first preset position is smaller than the stroke of the second preset position and smaller than the stroke of the third preset position. For example, the stroke of the first preset position can be set to a range of 20% to 40% of the maximum stroke of the push rod 22a, the stroke of the second preset position can be set to a range of 60% to 80% of the maximum stroke of the push rod 22a, and the stroke of the third preset position can be set to 90% to 100% of the maximum stroke of the push rod 22a. Of course, the specific settings should be reasonably limited according to actual needs. Similarly, the first preset threshold is smaller than the second preset threshold, and the specific settings should be reasonably limited according to actual needs.

[0057] By converting the mechanical motion of the push rod 22a into multi-level flushing commands, refined control of the smart toilet's flushing function is achieved. The core innovation lies in combining the push rod 22a's travel depth with real-time pressure to create a three-level flushing system: "Pre-flush - Standard Flush - Power Flush." This replaces the single feedback mode of traditional mechanical buttons and enhances the user experience of the smart toilet.
