[0022] The present invention provides a disinfection device and disinfection method for an intelligent toilet, which are respectively described below.

[0023] like Figure 1 As shown, the present invention provides a disinfection device for an intelligent toilet, comprising: a housing and a circuit board arranged in the housing; the circuit board is integrated with: Infrared laser detector 103, used to emit infrared laser to collect infrared information around the toilet; UVC (short-wave ultraviolet) sterilization module 102; The MCU (microcontroller unit) controller 101 is used to receive the infrared information, and when it is determined based on the infrared information that a person approaches the toilet, control the drive motor of the toilet to open the toilet lid and control the UVC sterilization module 102 to close; when it is determined based on the infrared information that a person leaves the toilet, control the drive motor to close the toilet lid and control the UVC sterilization module 102 to start working.

[0024] It is understandable that the present invention provides a disinfection device for a smart toilet, which mainly includes a housing and a circuit board. Among them, the circuit board is integrated with a seat sensor 106, an infrared laser detector 103, a light sensor 104, an MCU controller 101, two constant current drive control modules, a UVC sterilization module 102 and an illumination light module 105. The housing is designed with a receiving cavity, and the circuit board is placed in the receiving cavity. When the toilet lid is closed, the sterilization module can be automatically turned on for sterilization, and when the toilet lid is lifted, the sterilization module is automatically turned off, thereby realizing automatic sterilization of the smart toilet, making the toilet healthier and safer to use; and the light sensing module can sense the intensity of the surrounding light, and control the adaptive adjustment of the illumination light module 105 according to the intensity of the surrounding light, which is convenient for users to use the toilet when the light is dim, and can be automatically turned off when the light is sufficient, thereby saving energy and making the product more convenient and more humane.

[0025] In some embodiments, the circuit board further integrates: The first constant current driving control module 107 is used to receive a first PWM (pulse width modulation) driving signal sent by the MCU controller 101, generate a first driving current based on the first PWM driving signal, and control the UVC sterilization module 102 to turn on or off based on the first driving current.

[0026] In some embodiments, the circuit board further integrates: A light sensor 104, used to collect light signals from the area around the toilet; The lighting module 105 is used for lighting after being turned on; Among them, the MCU controller 101 is also used to receive the light signal, and when it is determined based on the light signal that the current light brightness value exceeds the preset brightness value, control the lighting module 105 to turn off the lighting function, and when it is determined based on the light signal that the current light brightness value is lower than the preset brightness value, control the lighting module 105 to turn on the lighting function.

[0027] In some embodiments, the MCU controller 101 is further used to adjust the brightness of the light emitted by the lighting module 105 according to the current light brightness value after controlling the lighting module 105 to turn on the lighting function.

[0028] In some embodiments, the circuit board further integrates: The second constant current drive control module 108 is used to receive the second PWM drive signal sent by the MCU controller 101, and generate a second drive current based on the second PWM drive signal, and control the lighting module 105 to turn on and off based on the second drive current, and after the lighting module 105 is turned on, adjust the brightness of the light emitted by the lighting module 105 according to the current light brightness value.

[0029] In some embodiments, the circuit board further integrates: A seat sensor 106 is used to collect signals when a person sits on the toilet; Among them, the MCU controller 101 is also used to receive a signal when a person sits on the toilet, and within the first target time after the toilet lid is opened, it is determined based on the signal when a person sits on the toilet that no person is sitting down, and based on the infrared information, it is determined that there is no person around the toilet, and then the light sensor 104 and the lighting module 105 are controlled to stop working.

[0030] In some embodiments, the color temperature of the light emitted by the lighting module 105 is between 2700K and 10000K.

[0031] It is understandable that the color temperature of the light emitted by the lighting module 105 may be 2700K, 5000K or 10000K.

[0032] In some embodiments, the UVC sterilization module 102 includes a plurality of AlGaN-based deep ultraviolet LEDs.

[0033] In some embodiments, the MCU controller 101 is further used to control the UVC sterilization module 102 to start working at a preset frequency when the closing time of the toilet lid reaches a second target time and is not opened.

[0034] In some embodiments, the disinfection device of the smart toilet provided by the present invention includes: The seat sensor 106 is used to collect signals when a person sits down and detect whether someone is using the toilet.

[0035] The infrared laser detector 103 is used to detect whether someone is passing by, so that the toilet lid is automatically opened when someone approaches and automatically closed when the person leaves.

[0036] The light sensor 104 is used to collect ambient light to achieve adaptive brightness adjustment, that is, when the brightness detected by the light sensor 104 reaches or exceeds the set brightness value, the lighting function is automatically turned off, otherwise it is adaptively adjusted according to the ambient light, so that the ambient light is always maintained at the set brightness value.

[0037] The MCU controller 101 is connected to the seat sensor 106, the infrared laser sensor 103, and the light sensor 104, and is used to detect signals to generate corresponding control instructions.

[0038] The first constant current drive control module 107 is connected to the UVC sterilization module 102. According to the volt-ampere characteristics of the LED, a constant current drive is required to drive the LED chip; the first constant current drive control module 107 is connected to the MCU controller 101, and is used to generate a drive signal according to the control instruction of the MCU controller 101, and control the opening or closing of the UVC sterilization module 102 according to the generated first PWM signal.

[0039] The second constant current drive control module 108 is connected to the lighting light-emitting module 105. According to the volt-ampere characteristics of the LED, a constant current drive is required to drive the LED chip, and the drive also needs to support a PWM dimming function; the constant current drive control module is connected to the MCU controller 101, and is used to generate a drive signal according to the control instruction of the MCU controller 101, and adjust the current size of the constant current drive according to the generated second PWM signal, thereby realizing adaptive adjustment of the lighting.

[0040] The UVC sterilization module 102 is connected to the first constant current drive control module 107. A plurality of UVC ultraviolet lamp beads are integrated on a PCB board. The deep ultraviolet LED (250 nm<λ<285 nm) based on AlGaN destroys and terminates the DNA replication process of bacteria, spores and viruses through ultraviolet irradiation, thereby achieving the purpose of effective sterilization and inhibiting bacterial reproduction.

[0041] The lighting module 105 is connected to the second constant current drive control module 108, and integrates a plurality of white light beads on a PCB board. The color temperature can be designed to be 2700K-10000K according to user needs, so as to realize auxiliary lighting in darker environments.

[0042] When the infrared laser sensor 103 detects that someone is approaching, it transmits the detection signal to the MCU controller 101, and the MCU controller 101 outputs a corresponding signal to control the drive motor of the toilet lid, and the toilet lid is automatically opened at this time. In any case, as long as the lid is opened, the UVC sterilization module 102 is always in a closed state to prevent ultraviolet rays from causing harm to the human body; when the infrared laser detects that a person has left, the lid is automatically closed, and the UVC module starts working. It can be timed / delayed closed through the MCU controller 101. For example, when it is designed, closing the lid can kill the bacteria in the toilet wall within 2 minutes, then our program can be set to a timer / delay ≥ 2 minutes.

[0043] When the infrared laser sensor 103 detects that someone is approaching, the light sensor 104 also works at the same time, that is, when the lid is opened, the light sensor 104 is always in a detection state to collect ambient light. When the ambient light is ≥ the set brightness value, the MCU outputs a second PWM signal to the second constant current drive control module 108. At this time, the signal is 0%, and the lighting is not turned on; conversely, the MCU outputs a second PWM signal to the second constant current drive control module 108. At this time, the second PWM signal is automatically adjusted from 1% to 100%, and the second constant current drive control module 108 changes according to the change of the second PWM signal. The driving current also changes accordingly, thereby realizing adaptive adjustment of the brightness of the lamp beads and keeping the light at the set brightness value at all times; this situation is mainly convenient at night or when the surrounding environment is dark, using the smart toilet to provide an auxiliary lighting, which increases convenience and humanization.

[0044] When the toilet lid is opened, the seat sensor 106 will also be in the detection state. If no one is detected sitting within 2 minutes, and the infrared laser detection module does not detect anyone nearby, the undetected signal will be transmitted to the MCU controller 101, thereby turning off the detection of the light sensor 104. At this time, the lighting is always in the off state; when someone passes by the sensing area and re-triggers the infrared laser detection signal or the seat sensing sensor detects that someone is sitting, the control program is reactivated; this situation is to avoid the phenomenon that the lighting is always on when the toilet lid is opened manually but no one uses the toilet, and the ambient light is lower than the brightness setting value. Therefore, adding this design can reduce the phenomenon of wasting energy by turning on the lighting in a poor light environment.

[0045] When the toilet has not been used for a long time and the lid is closed, bacteria will slowly grow on the inner wall of the toilet over time, affecting safety during use. At this time, a fixed cycle time can be set through the MCU controller 101 to perform sterilization. For example, it can be designed that the MCU controller 101 outputs a first PWM signal to the first constant current drive control module 107 to start sterilization once, so as to realize the function of regular sterilization and keep the inner wall of the toilet clean and hygienic for a long time.

[0046] The present invention also provides a method for disinfecting a smart toilet, which is applied to the above-mentioned disinfecting device. Figure 2 As shown, the disinfecting method comprises: S201, emitting infrared laser based on the infrared laser detector 103 to collect infrared information around the toilet; S202, based on the MCU controller 101 receiving the infrared information, when it is determined based on the infrared information that a person approaches the toilet, the drive motor is controlled to open the toilet lid and the UVC sterilization module 102 is controlled to close; when it is determined based on the infrared information that a person leaves the toilet, the drive motor is controlled to close the toilet lid and the UVC sterilization module 102 is controlled to start working.
