Technical Field

[0001] This application relates to the field of toilet technology, and in particular to a toilet. Background Technology

[0002] With the continuous development of electronic technology, smart toilets are becoming increasingly popular. Smart toilets are used in bathrooms, which are relatively humid and therefore prone to bacterial growth, leading to mold, yellowing, blackening, and odor. Bacteria mainly grow on the internal components of the smart toilet seat, the space inside the ceramic bowl, the ceramic wall, and inside the seat.

[0003] Although smart toilets with sterilization and disinfection devices have appeared on the market, their complex design structure leads to high production costs, and their sterilization and disinfection effects are poor. As a result, these smart toilets are difficult to popularize in people's lives. Utility Model Content

[0022] Figure 1 This is a structural schematic diagram of a toilet provided in an embodiment of this application. Figure 1 As shown, the toilet 10 includes a toilet seat 102, a housing space 104, a toilet bowl cavity 106, and a first sensor, as... Figure 2 As shown, the housing space 104 includes a controller 1042, a plasma generator 1044, a drying device 1046, and a spray gun 1048.

[0023] The controller 1042 is electrically connected to the plasma generator 1044, the first sensor, the drying device 1046, and the spray gun 1048.

[0024] The first sensor is used to detect the first signal.

[0025] The controller 1042 is configured to, when the value of the first signal is less than or equal to a first threshold, or when the value of the first signal is greater than or equal to a second threshold, control the plasma generator 1044 to generate positive and negative ions, control the drying device 1046 to diffuse positive and negative ions from the housing space 104 into the toilet bowl cavity 106 under the blowing action of the drying device 1046, and / or control the spray gun 1048 to diffuse positive and negative ions from the housing space 104 into the toilet bowl cavity 106 under the guiding action of the spray gun 1048.

[0026] The toilet 10 is a bathroom fixture used to receive and process human excrement. It has a flushing function to clean the toilet bowl 106 containing human excrement and to remove the excrement. The toilet bowl 106 of the toilet 10 can be made of ceramic, stainless steel, or other materials.

[0027] The toilet seat 102 is a component installed above the toilet 10 to cover the opening of the toilet bowl cavity 106 to prevent odors from escaping and maintain a hygienic environment for the toilet 10. The toilet seat 102 can be connected to the toilet seat of the toilet 10, and both the toilet seat 102 and the toilet seat can be opened for human use of the toilet 10.

[0028] In addition to the toilet seat 102, the toilet 10 also includes a toilet base. The housing space 104, the toilet bowl cavity 106, and the first sensor are all located on the toilet base.

[0029] The housing space 104 is the core component inside the toilet 10 base, which integrates the controller 1042, plasma generator 1044, drying device 1046, and spray gun 1048. Since the housing space 104 integrates multiple devices and components, it is the basis for the toilet 10 to achieve the purification function of sterilization, disinfection, and deodorization.

[0030] The toilet bowl cavity 106 is the space inside the toilet 10 used to hold excrement, and is located below the toilet lid 102.

[0031] The first sensor is used to detect whether a human body is sitting on the toilet 10. Optionally, the first sensor can be a distance sensor, a pressure sensor, or other sensors. For example, the distance sensor can be a lidar sensor, an infrared sensor, an ultrasonic sensor, etc.

[0032] Optionally, the first sensor can be disposed at any location in the toilet seat 102, the housing space 104, or the toilet bowl cavity 106. For example, if the first sensor is a distance sensor, the first sensor can be disposed in the toilet seat 102 or the toilet bowl cavity 106; if the first sensor is a pressure sensor, the first sensor can be disposed on the seat ring connected to the toilet seat 102.

[0033] The first signal corresponds to the type of the first sensor. For example, if the first sensor is a ranging sensor, the first signal is the distance signal measured by the first sensor; if the first sensor is a pressure sensor, the first signal is the pressure signal measured by the first sensor.

[0034] Optionally, the first threshold and the second threshold correspond to different types of first signals, for example, the first threshold may correspond to a distance signal and the second threshold may correspond to a pressure signal.

[0035] Optionally, when the first sensor is a ranging sensor, the first signal, which is the distance signal, is obtained by reflecting the ranging signal emitted by the ranging sensor. Since the ranging signal emitted by the ranging sensor will not be reflected by the human body when no human body is sitting on the toilet 10, but will be reflected by the human body when a human body is sitting on the toilet 10, that is, if the value of the first signal obtained after the reflection of the ranging signal is relatively small, it can be determined that a human body is sitting on the toilet 10. Based on this, in an exemplary embodiment, when the first sensor is a ranging sensor, the controller 1042 is used to control the plasma generator 1044 to operate and generate positive and negative ions when the value of the first signal is less than or equal to a first threshold, control the drying device 1046 to operate so that the positive and negative ions diffuse from the housing space 104 to the toilet bowl cavity 106 under the blowing action of the drying device 1046, and / or control the spray gun 1048 to operate so that the positive and negative ions diffuse from the housing space 104 to the toilet bowl cavity 106 under the guiding action of the spray gun 1048.

[0036] Optionally, when the first sensor is a pressure sensor, since the pressure sensor naturally cannot sense the first signal as a pressure signal when no human body is sitting on the toilet 10, but can sense the pressure applied by the human body when a human body is sitting on the toilet 10, it can sense the first signal. That is to say, in this case, if the first signal is relatively large, it can be determined that a human body is sitting on the toilet 10. Based on this, in an exemplary embodiment, when the first sensor is a pressure sensor, the controller 1042 is used to control the plasma generator 1044 to operate and generate positive and negative ions when the value corresponding to the first signal is greater than or equal to the second threshold, control the drying device 1046 to operate so that the positive and negative ions diffuse from the housing space 104 to the toilet bowl cavity 106 under the blowing action of the drying device 1046, and / or control the spray gun 1048 to operate so that the positive and negative ions diffuse from the housing space 104 to the toilet bowl cavity 106 under the guiding action of the spray gun 1048.

[0037] Optionally, the controller 1042 may be a microcontroller, MCU, PLC, intelligent control chip, or other components with data processing and control capabilities.

[0038] The plasma generator 1044 is a component used to generate positive and negative ions. In the toilet 10, the positive and negative ions generated by the plasma generator 1044 will destroy the growth of bacteria, viruses, and particulate matter, causing the bacteria to die. Therefore, positive and negative ions can be used for sterilization, deodorization, and air purification.

[0039] Optionally, the controller 1042 can be used to control the plasma generator 1044 to generate positive and negative ions at regular intervals.

[0040] The drying device 1046 is a component in the toilet 10 used to generate airflow to blow away water molecules and achieve the drying function. In this embodiment, the drying device 1046 is also used in conjunction with the plasma generator 1044 to diffuse positive and negative ions from the housing space 104 into the toilet bowl cavity 106.

[0041] The spray gun 1048 is a component in the toilet 10 used to spray water to perform a cleaning function. Since the spray gun 1048 includes a retractable spray bar for guiding the water flow, the spray gun 1048 can guide positive and negative ions to diffuse from the housing space 104 into the toilet bowl cavity 106 via the spray bar.

[0042] Because the positive and negative ions in this embodiment can diffuse from the housing space 104 into the toilet bowl cavity 106 under the blowing action of the drying device 1046 or the guiding action of the spray gun 1048, the positive and negative ions can also purify the housing space 104 by sterilizing, disinfecting, and deodorizing. That is to say, both the housing space 104 and the toilet bowl cavity 106 can be purified by sterilization, disinfection, and deodorization. At the same time, since the drying device 1046 and the spray gun 1048 are commonly used devices in smart toilets 10, by cleverly diffusing positive and negative ions from the housing space 104 into the toilet bowl cavity 106 through the drying device 1046 or the spray gun 1048, the durability of the toilet 10 can be improved while reducing the cost of the toilet 10 provided in this embodiment.

[0043] Since positive and negative ions pass through the housing space 104, which includes the controller 1042, plasma generator 1044, drying device 1046, and spray gun 1048, the positive and negative ions also have a purifying effect of sterilization, disinfection, and deodorization on the controller 1042, plasma generator 1044, drying device 1046, and spray gun 1048. Other devices or components located in the housing space 104 can also receive the purifying effect of positive and negative ions, and therefore will not be described in detail below. Similarly, since positive and negative ions diffuse into the toilet bowl cavity 106, they also have a purifying effect of sterilization, disinfection, and deodorization on the devices or components included in the toilet bowl cavity 106, and therefore will not be described in detail below.

[0044] The toilet includes a toilet seat, a housing space, a toilet bowl cavity, and a first sensor. The housing space includes a controller, a plasma generator, a drying device, and a spray gun. The controller is electrically connected to the plasma generator, the first sensor, the drying device, and the spray gun. The first sensor is used to detect a first signal. The controller is used to control the plasma generator to generate positive and negative ions, control the drying device to diffuse positive and negative ions from the housing space into the toilet bowl cavity under the blowing action of the drying device, and / or control the spray gun to diffuse positive and negative ions from the housing space into the toilet bowl cavity under the guiding action of the spray gun. The toilet provided in this application embodiment is equipped with a plasma generator, which allows the positive and negative ions generated by the plasma generator to diffuse from the shell space into the toilet bowl cavity under the action of the drying device or spray gun. As a result, both the shell space and the toilet bowl cavity can be purified by sterilization, disinfection, and deodorization under the action of positive and negative ions. Furthermore, by improving the hygienic environment of the toilet, the number of bacteria in the toilet can be reduced, thereby improving the durability of the toilet.

[0045] In one exemplary embodiment, positive and negative ion diffusion outlets are respectively provided on the four sides of the plasma generator, which are used to diffuse positive and negative ions inside the plasma generator into the housing space.

[0046] The positive and negative ion diffusion outlets should be located on the plasma generator to ensure that positive and negative ions can be effectively released from inside the plasma generator and diffuse into the housing space. Optionally, the four surfaces of the plasma generator with positive and negative ion diffusion outlets can be the four sides of the plasma generator other than the upper and lower surfaces parallel to the ground.

[0047] In one exemplary embodiment, such as Figure 3 As shown, the plasma generator 1044 includes positive and negative ion diffusion channels 10440 leading to the housing space 104, positive and negative ion diffusion channels 10440 leading to the toilet chamber 106, and positive and negative ion diffusion channels 10440 leading to the drying device 1046.

[0048] The number of positive and negative ion diffusion channels 10440 leading to the shell space 104, positive and negative ion diffusion channels 10440 leading to the toilet bowl cavity 106, and positive and negative ion diffusion channels 10440 leading to the drying device 1046 can each include at least one.

[0049] In a straightforward manner, the positive and negative ion diffusion channel 10440 can guide the positive and negative ions generated inside the plasma generator 1044 to the corresponding positions in the toilet. For example, the positive and negative ion diffusion channel 10440 leading to the housing space 104 can guide positive and negative ions from the plasma generator 1044 into the housing space 104, the positive and negative ion diffusion channel 10440 leading to the toilet bowl cavity 106 can guide positive and negative ions from the plasma generator 1044 into the toilet bowl cavity 106, and the positive and negative ion diffusion channel 10440 leading to the drying device 1046 can guide positive and negative ions from the plasma generator 1044 into the drying device 1046.

[0050] In a straightforward manner, the controller 1042 controls the plasma generator 1044 to operate and generate positive and negative ions, so that the positive and negative ions inside the plasma generator 1044 diffuse to the corresponding positions under the guidance of the positive and negative ion diffusion channel 10440.

[0051] It is easy to understand that at least some of the positive and negative ions that enter the positive and negative ion diffusion channel 10440 leading to the drying device 1046 will diffuse from the housing space 104 into the toilet bowl cavity 106 under the blowing action of the drying device 1046.

[0052] Optionally, the positive and negative ion diffusion channel 10440 can be a straight channel or a curved channel. Optionally, when the toilet's purification requirements for sterilization, disinfection, and deodorization prioritize purification efficiency over purification uniformity, the positive and negative ion diffusion channel 10440 can be set as a straight channel; when the toilet's purification requirements prioritize purification uniformity over purification efficiency, the positive and negative ion diffusion channel 10440 can be set as a curved channel.

[0053] Optionally, the positive and negative ion diffusion channel 10440 can be made of metal or insulating material. Optionally, when the toilet's purification requirements for sterilization, disinfection, and deodorization prioritize purification efficiency over purification uniformity, the positive and negative ion diffusion channel 10440 made of metal can be selected; when the toilet's purification requirements prioritize purification uniformity over purification efficiency, the positive and negative ion diffusion channel 10440 made of insulating material can be selected.

[0054] In this embodiment, the plasma generator is provided with positive and negative ion diffusion outlets on four sides, or includes positive and negative ion diffusion channels leading to the housing space, positive and negative ion diffusion channels leading to the toilet bowl cavity, and positive and negative ion diffusion channels leading to the drying device. Thus, the plasma generator can smoothly diffuse the positive and negative ions generated inside it to the corresponding positions on the toilet, so that both the housing space and the toilet bowl cavity can be purified by sterilization, disinfection, and deodorization under the action of positive and negative ions. Furthermore, by improving the hygienic environment of the toilet, the number of bacteria in the toilet can be reduced, thereby improving the durability of the toilet.

[0055] In one exemplary embodiment, the drying device includes a drying fan and a drying duct, the drying fan being electrically connected to a controller.

[0056] The controller is used to control the operation of the drying fan so that positive and negative ions diffuse from the drying air duct into the toilet bowl cavity.

[0057] The drying fan is a component in the drying device used to generate a continuous airflow, mixing the positive and negative ions produced by the plasma generator with the air before blowing them into the drying duct. The drying fan not only helps the toilet quickly remove surface moisture but also promotes the diffusion of positive and negative ions to achieve a purifying effect of sterilization, disinfection, and deodorization.

[0058] The drying duct is a component in a drying device used to guide the flow direction of the airflow blown by the drying fan.

[0059] In one exemplary embodiment, the toilet seat includes a toilet seat drive component; the spray gun includes a nozzle, a spray gun drive component, and a telescopic spray bar, with the nozzle disposed at one end of the spray bar near the toilet bowl cavity and the spray gun drive component disposed at one end of the spray bar near the controller.

[0060] The controller is electrically connected to both the toilet seat drive component and the spray gun drive component.

[0061] The controller is further configured to generate a first driving signal to drive the toilet seat transmission component to move the toilet seat closer to and fit against the top of the toilet bowl cavity when the value corresponding to the first signal increases from less than or equal to the first threshold to greater than the first threshold, or when the value corresponding to the first signal decreases from greater than or equal to the second threshold to less than the second threshold; and to generate a second driving signal to drive the spray gun transmission component to move the spray bar from the housing space to the toilet bowl cavity, so that positive and negative ions diffuse from the housing space sequentially through the spray bar and the nozzle into the toilet bowl cavity.

[0062] The toilet seat transmission component is an electromechanical structure inside the toilet seat used to drive the opening and closing of the toilet seat. Optionally, the toilet seat transmission component may include components such as a toilet seat transmission motor, gears, and connecting rods, so that the toilet seat can be driven by the first drive signal of the controller to move the toilet seat closer to and fit against the upper part of the toilet bowl cavity.

[0063] The nozzle is the component in a spray gun used to spray water or positive and negative ions. After aiming the nozzle at the area of ​​the toilet that needs cleaning, spraying water onto that area will clean it.

[0064] The spray gun drive component is an electromechanical structure inside the spray gun used to drive the extension and retraction of the spray boom. Optionally, the spray gun drive component may include components such as a spray gun drive motor, gears, and connecting rods, so that the spray gun drive component can drive the spray boom to extend from the housing space into the toilet bowl cavity under the drive of the second drive signal of the controller.

[0065] In order to allow positive and negative ions to diffuse from the shell space through the spray bar and nozzle into the toilet bowl cavity, the spray bar is hollow to allow positive and negative ions to pass through it.

[0066] In this embodiment, when the value corresponding to the first signal increases from less than or equal to the first threshold to greater than the first threshold, or when the value corresponding to the first signal decreases from greater than or equal to the second threshold to less than the second threshold, that is, when the controller detects that the human body has left the toilet based on the first signal, the controller drives the toilet lid to approach and fit against the top of the toilet bowl cavity to close the connection channel between the toilet bowl cavity and the outside air, and drives the spray bar to extend from the shell space into the toilet bowl cavity. Thus, positive and negative ions can diffuse from the shell space into the toilet bowl cavity. And because the toilet lid is on top of the toilet bowl cavity, positive and negative ions will not overflow from the toilet bowl cavity to diffuse to the outside of the toilet. In this way, positive and negative ions can effectively play a full role in sterilizing, disinfecting, and deodorizing the toilet bowl cavity.

[0067] In one exemplary embodiment, such as Figure 4 As shown, the housing space 104 also includes a nozzle drive component 1043, and the toilet bowl cavity 106 includes a plurality of water spray holes 1062.

[0068] The nozzle drive component 1043 is electrically connected to the controller 1042.

[0069] The controller 1042 is also used to generate a third drive signal to drive the nozzle transmission component 1043 to drive the nozzle 1045 to rotate in a preset direction to the nearest target water spray hole 1062 and stay there for a first preset time, so that positive and negative ions diffuse from the housing space 104 through the spray bar and the nozzle 1045 to the target water spray hole 1062.

[0070] The nozzle drive component 1043 is an electromechanical structure in the spray gun used to control the rotation of the nozzle 1045. The nozzle drive component 1043 ensures that the nozzle 1045 is accurately aligned with each water spray hole 1062, allowing positive and negative ions to diffuse sequentially from the housing space 104 through the spray bar and nozzle to the target water spray hole 1062, thereby achieving the purification function of sterilization, deodorization, and disinfection of the water spray hole 1062. Optionally, the nozzle drive component 1043 may include components such as a nozzle rotation motor, gears, and connecting rods.

[0071] The water spray hole 1062 is an opening located inside the toilet bowl cavity 106 for spraying water to clean the inside of the toilet bowl. Optionally, the toilet bowl cavity 106 includes 5 water spray holes 1062, and the 5 water spray holes 1062 are evenly and uniformly arranged in the toilet bowl cavity 106.

[0072] Optionally, the first preset duration can be 1 minute, 2 minutes, 3 minutes or other durations.

[0073] Optionally, the third drive signal may be generated by the controller 1042 when the value corresponding to the first signal increases from less than or equal to the first threshold to greater than the first threshold, or when the value corresponding to the first signal decreases from greater than or equal to the second threshold to less than the second threshold.

[0074] Optionally, the preset direction can be either counterclockwise or clockwise rotation.

[0075] Optionally, the controller 1042 generates multiple third drive signals to enable the nozzle 1045 to remain at all the spray holes 1062 for a first preset time, thereby ensuring that all the spray holes 1062 in the toilet bowl cavity 106 can receive the purification effect of positive and negative ions.

[0076] Optionally, when the spray bar extends from the housing space 104 into the toilet bowl cavity 106, the nozzle 1045 has an initial position, which can be the edge of the toilet bowl cavity 106. Thus, the nozzle 1045 can start purifying from the water spray hole 1062 at the outermost edge, and complete the purification of all water spray holes 1062 after rotating one revolution in a preset direction.

[0077] Since the spray gun transmission component 1043 drives the spray bar to extend from the housing space 104 into the toilet bowl cavity 106, and the nozzle 1045 is located at one end of the spray bar near the toilet bowl cavity 106, the nozzle 1045 extends into the toilet bowl cavity 106 at this time.

[0078] For example, such as Figure 3 As shown, the toilet bowl cavity 106 includes five spray holes 1062 (spray hole 1, spray hole 2, ..., spray hole 5). The first preset duration is 2 minutes. After the controller 1042 generates the first third drive signal to drive the nozzle transmission component 1043 to drive the nozzle 1045 to rotate in the preset direction to the nearest spray hole 10621 and stay for 2 minutes, it generates the second third drive signal to make the nozzle 1045 rotate to the spray hole 10622 adjacent to the spray hole 10621 and stay for 2 minutes... Finally, it generates the fifth third drive signal to make the nozzle 1045 rotate to the spray hole 10625 adjacent to the spray hole 10624 and stay for 2 minutes. Thus, the purification of the five spray holes 1062 by positive and negative ions is completed through the nozzle 1045.

[0079] In this embodiment, positive and negative ions are diffused from the shell space to the water spray hole in the toilet bowl cavity through the nozzle, so that the positive and negative ions can play a purifying role in sterilizing, disinfecting and deodorizing the water spray hole. In this way, by improving the sanitary environment of the toilet, the number of bacteria in the toilet can be reduced and the durability of the toilet can be improved.

[0080] In one exemplary embodiment, such as Figure 2 As shown, the housing space 104 also includes a communication device 10410, which is electrically connected to the controller 1042.

[0081] The communication device 10410 is used to receive control signals from an external terminal and send the control signals to the controller 1042.

[0082] The controller 1042 is also used to control the state of the plasma generator in response to a control signal; the state of the plasma generator is either an operating state or a standby state.

[0083] The external terminal can be a user's personal computer, smartphone, smart wearable device, or other terminal, and thus the control signal is initiated by the user on their terminal for the toilet controller 1042.

[0084] Optionally, the communication device 10410 may include a Bluetooth module or a wireless network module.

[0085] In this embodiment, since the housing space also includes a communication device electrically connected to the controller, the communication device can receive control signals initiated by the user on an external terminal for the controller and send the control signals to the controller. Thus, the controller can respond to the control signals to control the state of the plasma generator to either a working state or a standby state. By realizing the user's remote control of the plasma generator, the sterilization, disinfection, and deodorization purification effect of the toilet is made controllable and flexible.

[0086] In one exemplary embodiment, such as Figure 2 As shown, the housing space 104 also includes a deodorizing fan 10412, which is electrically connected to the controller 1042.

[0087] The controller 1042 is also used to control the deodorizing fan 10412 to exhaust air from the toilet bowl cavity after the toilet seat approaches and adheres to the top of the toilet bowl cavity, so that the toilet bowl cavity is in a negative pressure state.

[0088] In this process, after the toilet seat approaches and fits against the top of the toilet bowl cavity, the deodorizing fan 10412 exhausts the toilet bowl cavity, which can reduce the air pressure value of the toilet bowl cavity in a closed state.

[0089] Because positive and negative ions diffuse within the toilet bowl cavity after the toilet seat is close to and adheres to it, these ions also purify the side of the toilet seat closest to the bowl cavity by killing bacteria, eliminating odors, and disinfecting. Similarly, when the toilet seat includes the attached seat ring, the seat ring also receives the purifying effect of positive and negative ions.

[0090] It should be noted that, in order to avoid the toilet bowl cavity being too low in air pressure and thus preventing the user from being unable to open the toilet lid, the power of the deodorizing fan 10412 when venting the toilet bowl cavity should not be too high. Optionally, the power of the deodorizing fan 10412 when venting the toilet bowl cavity can be less than or equal to the preset power. The preset power setting should ensure that the negative pressure state of the toilet bowl cavity is a slight negative pressure state, so as to avoid the toilet lid being unable to be opened from the outside.

[0091] In this embodiment, after the toilet seat approaches and adheres to the upper part of the toilet bowl cavity, the controller and the deodorizing fan work together to put the toilet bowl cavity into a negative pressure state, which can keep the positive and negative ions in the toilet bowl cavity without overflowing, thereby further improving the purification effect of positive and negative ions on the toilet bowl cavity for sterilization, disinfection and deodorization.

[0092] In one exemplary embodiment, such as Figure 5 As shown, the toilet also includes a second sensor 1064 located in the toilet bowl cavity 106, and the housing space 104 also includes a timer 10414.

[0093] The controller 1042 is electrically connected to the second sensor 1064 and the timer 10414 respectively.

[0094] The second sensor 1064 is used to detect the second signal of the toilet bowl cavity 106.

[0095] Timer 10414 is used to detect a first duration for which the value corresponding to the second signal is less than or equal to the second threshold.

[0096] The controller 1042 is also used to control the plasma generator 1044 to switch from the working state to the standby state when the first maintenance duration is greater than or equal to the second preset duration.

[0097] The second sensor 1064 can be an air quality sensor, an odor detection sensor, a bacteria detection sensor, or other sensors.

[0098] The second signal corresponds to the type of the second sensor 1064. For example, if the second sensor 1064 is an odor detection sensor, the second signal is the odor concentration signal measured by the second sensor 1064; if the second sensor 1064 is a bacteria detection sensor, the second signal is the number of bacteria measured by the second sensor 1064.

[0099] Optionally, the second preset duration can be 5 minutes, 8 minutes, 10 minutes or other durations.

[0100] The second signal corresponds to a value less than or equal to the second threshold, indicating that the odor concentration and / or bacterial content in the toilet bowl cavity 106 is low.

[0101] In one exemplary embodiment, such as Figure 2 As shown, the housing space 104 also includes a third sensor 10416 and a timer 10414.

[0102] The controller 1042 is electrically connected to the third sensor 10416 and the timer 10414 respectively.

[0103] The third sensor 10416 is used to detect the third signal in the housing space 104.

[0104] Timer 10414 is used to detect the second duration of the third signal corresponding to a value that is less than or equal to a third threshold.

[0105] The controller 1042 is also used to control the plasma generator 1044 to switch from the working state to the standby state when the second maintenance duration is greater than or equal to the third preset duration.

[0106] The third sensor 10416 can be an air quality sensor, an odor detection sensor, a bacteria detection sensor, or other sensors.

[0107] The third signal corresponds to the type of the third sensor 10416. The specific content of the third signal is the same as that of the second signal, so it will not be described again here.

[0108] Optionally, the third preset duration can be 5 minutes, 8 minutes, 10 minutes or other durations.

[0109] The second signal value is less than or equal to the second threshold, indicating that the odor concentration and / or bacterial content in the toilet bowl cavity is low.

[0110] In this embodiment, when the odor concentration and / or bacterial content in the toilet bowl cavity is low, meaning the hygienic environment of the toilet has been maintained for a relatively long time, the controller switches the plasma generator 1044 from the working state to the standby state. This avoids the plasma generator 1044 from needing to maintain a long working state even when the toilet bowl cavity has been fully purified, thus avoiding the adverse situation of the plasma generator 1044 causing large energy consumption and improving the durability of the toilet.

[0111] In one exemplary embodiment, the third sensor 10416 is a bacterial detection sensor.

[0112] In this embodiment, the third sensor used to detect the third signal in the housing space is a bacterial detection sensor. Thus, the controller can maintain the working state of the plasma generator when the bacterial content in the housing space is high, so that the plasma generator can purify the housing space by sterilizing, deodorizing and sterilizing. In turn, it can prevent the multiple devices included in the housing space from being corroded by mold caused by bacterial growth, thereby reducing their working performance and improving the durability of the toilet.

[0113] In an exemplary embodiment, the toilet also includes a flush button switch connected to a controller. The flush button switch is used to respond to a flush command initiated by a user. Upon responding to the flush command, the flush button switch generates a flush signal and sends it to the controller, so that the controller controls both the second sensor and the second sensor to be in a working state.

[0114] In an exemplary embodiment, the controller is further configured to control the plasma generator to switch from an operating state to a standby state when the first maintenance duration is greater than or equal to a second preset duration and the second maintenance duration is greater than or equal to a third preset duration.

[0115] In one exemplary embodiment, the housing space also includes a timer connected to the controller.

[0116] The controller is also used to switch the plasma generator from the working state to the standby state when the timer detects that the working duration of the plasma generator is greater than or equal to a fourth preset duration.

[0117] Optionally, the fourth preset duration can be 5 minutes, 15 minutes, 30 minutes or other durations.

[0118] In this embodiment, when the plasma generator operates for a long time, the controller can automatically switch the plasma generator from the working state to the standby state. This avoids the plasma generator from having to maintain a long working state even after the toilet bowl cavity has been fully purified, thus avoiding the adverse situation of the plasma generator causing large energy consumption and improving the durability of the toilet.

[0119] In an exemplary embodiment, the controller is further configured to control the second sensor and the third sensor to switch from standby state to working state respectively when the timer detects that the working duration of the plasma generator is greater than or equal to a fifth preset duration.

[0120] Optionally, the fifth preset duration can be 3 minutes, 5 minutes, 7 minutes or other durations.

[0121] In this embodiment, the second and third sensors will only enter the working state after the plasma generator has been working for a certain period of time, thereby improving the service life of the second and third sensors.
