[0002] With increasing public awareness of health, people have higher and higher requirements for personal hygiene. Disinfection boxes, as an effective hygiene tool, are gradually being widely used in daily life. Especially in the field of personal care, the hygiene of everyday cleaning tools such as toothbrushes and razors directly affects our health. These cleaning tools are prone to bacterial growth during use; therefore, ensuring they are effectively disinfected after use is particularly important. Disinfection boxes use technologies such as ultraviolet light and hot steam to quickly remove bacteria and viruses from the surface of tools, effectively preventing bacterial growth in humid environments and thus protecting the user's health.

[0053] Most sterilization boxes on the market rely on wired charging, which has limitations. First, wired charging restricts the portability of the sterilization box, requiring users to place the device near a specific outlet, causing inconvenience. Second, the need to connect and disconnect the cord each time it's charged increases operational complexity and impacts the user experience. Furthermore, prolonged use can cause wear and tear on the charging port, shortening the lifespan of the charging box.
[0054] This utility model proposes a circuit for a disinfection box.
[0055] Please see Figure 1 In one embodiment of this utility model, the disinfection box circuit includes:
[0056] Battery 10;
[0057] The disinfection circuit 20 has its power supply terminal connected to the battery 10 and is used to disinfect the equipment to be disinfected.
[0058] The attitude detection circuit 30 is connected to the battery 10. The attitude detection circuit 30 is used to detect the placement attitude of the disinfection box and output the corresponding attitude detection signal.
[0059] The touch control circuit 40 is connected to the battery 10 at its power supply terminal. The touch control circuit 40 is used to output corresponding touch signals when triggered by the user. The touch signals include charging switch signals and disinfection switch signals.
[0060] The output terminal of the wireless charging circuit 50 is connected to the battery 10. The wireless charging circuit 50 is used to receive wireless charging signals and convert the wireless charging signals into charging power output to charge the battery 10.
[0061] The main control circuit 60 is connected to the battery 10, the signal output terminal of the posture detection circuit 30, the signal output terminal of the touch control circuit 40, the controlled terminal of the disinfection circuit 20, and the controlled terminal of the wireless charging circuit 50. The main control circuit 60 is used to control the operation of the wireless charging circuit 50 according to the charging switch signal, and to control the operation of the disinfection circuit 20 according to the disinfection switch signal when the disinfection box is detected to be in an inverted posture according to the posture detection signal.
[0062] It should be noted that the sterilization box can be rectangular or cylindrical in shape, with a hollow interior forming a sterilization chamber to hold items to be sterilized (such as electric toothbrushes, water flossers, and other cleaning tools). The sterilization box can have embedded ultraviolet lamps and other sterilization components in the top and side walls to ensure that ultraviolet light evenly irradiates the entire sterilization chamber during the sterilization process, achieving thorough sterilization without blind spots. To prevent ultraviolet leakage and potential harm to the human body, especially the eyes, the top and side walls of the sterilization box can be designed with opaque materials to effectively block ultraviolet light leakage. To enhance ease of use, the sterilization box can have an open bottom design, allowing users to place the box directly into position without moving the items to be sterilized and begin the sterilization process by snapping it shut. For example, when sterilizing an electric toothbrush head, the user simply fixes the electric toothbrush to its base, then inverts the sterilization box over the base and triggers the sterilization command. This enhances operational convenience. If the disinfection box is placed incorrectly upright, causing the ultraviolet lamp to shine directly into the user's eyes during sterilization, the automatic control will stop the disinfection process, thus enhancing the safety of using the disinfection box.
[0063] In this embodiment, the disinfection circuit 20 may include an ultraviolet LED (UVC LED), which emits ultraviolet light that can effectively kill bacteria and viruses. The attitude detection circuit 30 may include an accelerometer. When the disinfection box is upright, the gravitational acceleration mainly acts on the Z-axis (positive direction); when it is upside down, the gravitational acceleration acts in the opposite direction on the Z-axis (negative direction). The main control circuit 60 can read the accelerometer data and detect the upright / upside-down position of the disinfection box based on the acceleration value (positive or negative) on the Z-axis. The attitude detection circuit 30 may also include a gyroscope. The gyroscope detects the change in the rotation angle of the disinfection box. The main control circuit 60 can acquire the data detected by the gyroscope and combine it with the static gravity direction data to detect whether the disinfection box is upright or upside down. The attitude detection circuit 30 may also use a combination of an accelerometer and a gyroscope for detection, which is not limited here. The touch control circuit 40 may include a capacitive touch sensing chip. When a finger approaches or touches the touch surface, it changes the capacitance value at that location. The touch chip can detect this change and convert it into a digital signal, which is then sent to the main control circuit 60. The main control circuit 60 can identify whether a charging switch signal and / or a disinfection switch signal have been triggered based on this signal. Alternatively, the touch control circuit 40 may include a resistive touch sensing chip, which may consist of two layers of transparent conductive material that come into contact when pressed. The touch position can be determined by measuring the current at the touch point, and the main control circuit 60 can identify whether a charging switch signal and / or a disinfection switch signal have been triggered based on this current information. The wireless charging circuit 50 may include a receiving coil, a rectifier circuit, a voltage regulator circuit, and a protection circuit. The receiving coil can receive electromagnetic energy from the wireless transmitter. The rectifier circuit may include components such as diodes to convert the AC voltage induced by the receiving coil into a DC voltage. The voltage regulator circuit may include components such as voltage regulators to ensure a stable voltage supplied to the battery 10 or subsequent circuits. Please refer to [link to relevant documentation]. Figure 6 The main control circuit 60 may include an MCU chip, such as the STM32 series, which has rich peripheral interfaces such as UART, I2C, and SPI, and can realize communication connection with the disinfection circuit 20, the wireless charging circuit 50, etc.
[0064] In this embodiment, the posture detection circuit 30 can detect the placement posture of the disinfection box and output a corresponding posture detection signal to the main control circuit 60. When the user triggers the disinfection switch signal to indicate the start of disinfection via the touch control circuit 40, the main control circuit 60 activates the disinfection circuit 20 to start the disinfection operation only when the posture detection signal detects that the disinfection box is in an inverted posture, thereby avoiding direct ultraviolet radiation to the user and causing harm. It should be noted that the main control circuit 60 can be set with a preset disinfection time. When the disinfection switch signal is triggered to indicate that the disinfection function is turned on, the main control circuit 60 can control the disinfection circuit 20 to disinfect the device to be disinfected, and stop disinfection when the disinfection time exceeds the preset disinfection time, thus saving battery 10 power. The wireless charging circuit 50 can receive external wireless charging signals and convert them into power output suitable for charging battery 10. When the user triggers the charging switch signal to indicate the start of charging via the touch control circuit 40, the main control circuit 60 controls the wireless charging circuit 50 to start working and charge battery 10. Compared to existing technologies, this embodiment employs a built-in battery 10 and wireless charging technology. Users are no longer limited by the location of a specific socket and can use the disinfection box anytime, anywhere. Charging is simple and avoids wear and tear on the charging interface caused by frequent plugging and unplugging of power cords. This solves the problems of limited mobility, complex operation, and shortened lifespan associated with existing disinfection boxes that rely on wired charging. Furthermore, the disinfection circuit 20 is only activated when the disinfection box is in an inverted position, preventing ultraviolet light and other disinfection rays from directly shining into the user's eyes, thus enhancing the safety of using the disinfection box.
[0065] In this invention, the posture detection circuit 30 can detect the placement posture of the disinfection box and output a corresponding posture detection signal to the main control circuit 60. The user can trigger the disinfection switch signal via the touch control circuit 40. The main control circuit 60 will only activate the disinfection circuit 20 to perform the disinfection operation when it detects that the disinfection box is in an inverted posture based on the posture detection signal, thus avoiding harm to the user from incorrect usage postures, such as preventing direct ultraviolet radiation to the user's eyes. The wireless charging circuit 50 can receive external wireless charging signals and convert them into a power output suitable for charging the battery 10. When the user triggers the charging switch signal indicating the start of charging via the touch control circuit 40, the main control circuit 60 controls the wireless charging circuit 50 to start working and charge the battery 10. Compared with the prior art, this invention uses a built-in battery 10 and wireless charging technology. Users are no longer limited by the location of a specific socket and can use the disinfection box anytime, anywhere. The charging operation is simple and avoids wear and tear on the charging interface caused by frequent plugging and unplugging of wires. This solves the problems of limited mobility, complex operation, and shortened lifespan caused by existing disinfection boxes relying on wired charging. Moreover, the disinfection circuit 20 is only activated when the disinfection box is in an inverted position to perform the disinfection operation, which avoids the ultraviolet light or other light used for disinfection from directly shining into the user's eyes during disinfection, thus enhancing the safety of using the disinfection box.
[0066] Please see Figure 3 In one embodiment of this utility model, the wireless charging circuit 50 includes a coil L101, a first capacitor C101, a second capacitor C102, a first resistor R101, a second resistor R102, a third resistor R103, a first diode D101, a second diode D102, a third diode D103, a first switch Q101, a second switch Q102, and a Zener diode DW101;
[0067] The first output terminal of coil L101 and the first terminal of first capacitor C101 are connected to the anode of first diode D101. The cathode of first diode D101, one end of second capacitor C102, the first terminal of first switch Q101, and the anode of second diode D102 are connected to one end of third resistor R103. The second output terminal of coil L101, the other end of first capacitor C101, the other end of second capacitor C102, one end of second resistor R102, and the first terminal of second switch Q102 are grounded to the anode of Zener diode DW101. The third resistor R... The other end of 103, the controlled end of the first switch Q101, is connected to the second end of the second switch Q102. The cathode of the second diode D102 is connected to one end of the first resistor R101. The other end of the first resistor R101, the controlled end of the second switch Q102, and the other end of the second resistor R102 are connected to the first signal output terminal of the main control circuit 60. The second end of the first switch Q101 and the cathode of the Zener diode DW101 are connected to the anode of the third diode D103. The cathode of the third diode D103 is connected to the output terminal of the wireless charging circuit 50.
[0068] In this embodiment, when the disinfection box is close to the wireless charging pad, the coil L101 senses an alternating magnetic field and generates a current. The first capacitor C101, the first diode D101, and the second capacitor C102 form a rectification and preliminary filtering circuit, converting the AC current induced by the coil L101 into DC current and smoothing voltage fluctuations. The first resistor R101, the second resistor R102, the third resistor R103, and the first and second switching transistors Q101 and Q102 constitute a circuit that can be controlled by the main control circuit 60. When the main control circuit 60 detects a charging start command, it can control the conduction state of the second switching transistor Q102 via a control signal, thereby controlling the conduction state of the first switching transistor Q101, allowing current to flow to the battery 10 for charging. The main control circuit 60 can also adjust the charging current input to the battery 10 by controlling the conduction frequency of the first switching transistor Q101 to ensure a safe and efficient charging process. In this embodiment, the first switch Q101 can be a PMOS transistor, and the second switch Q102 can be an NMOS transistor. When the gate input of the second switch Q102 is high, its drain and source are connected. Therefore, when the gate input of the first switch Q101 is low, its drain and source are also connected, allowing charging of the battery 10. Similarly, when the gate input of the second switch Q102 is low, its drain and source are turned off. Therefore, the drain and source of the first switch Q101 are also turned off, stopping charging.
[0069] In one feasible embodiment, the wireless charging circuit 50 further includes a fourth resistor R104, a fifth resistor R105, and a third switch Q103;
[0070] One end of the fourth resistor R104 is connected to the negative terminal of the first diode D101. The other end of the fourth resistor R104 and one end of the fifth resistor R105 are connected to the controlled terminal of the third switch Q103. The other end of the fifth resistor R105 is grounded to the first terminal of the third switch Q103. The second terminal of the third switch Q103 is connected to the first signal input terminal of the main control circuit 60.
[0071] In this embodiment, the fourth resistor R104, the fifth resistor R105, and the third switch Q103 can constitute a charging detection feedback circuit. The third switch Q103 can be an NMOS transistor. When the coil L101 receives a wireless charging signal, the third switch Q103 is turned on and can output a high-level CHARG_DET signal. The main control circuit 60 can then output a prompt message based on this CHARG_DET signal to indicate that the wireless charging mode has been entered. When the coil L101 does not receive a wireless charging signal, the third switch Q103 is turned on and can output a low-level CHARG_DET signal. The main control circuit 60 can then output a prompt message based on this CHARG_DET signal to indicate that the wireless charging mode has not been entered, thus facilitating wireless charging prompts.
[0072] Please see Figure 4 In one embodiment of this utility model, the touch control circuit 40 includes a fourth resistor R104, a fifth resistor R105, a sixth resistor R106, a seventh resistor R107, a third capacitor C103, a fourth capacitor C104, a touch input terminal TH, and a touch chip U101.
[0073] The touch input terminal TH is connected to one end of the fourth resistor R104. The other end of the fourth resistor R104 and one end of the third capacitor C103 are connected to the IN pin of the touch chip U101. The other end of the third capacitor C103 and one end of the fourth capacitor C104 are grounded to the VSS pin of the touch chip U101. The QO pin of the touch chip U101 is connected to one end of the fifth resistor R105. The other end of the fifth resistor R105 and one end of the sixth resistor R106 are connected to the second signal input terminal of the main control circuit 60. The other end of the sixth resistor R106 and one end of the seventh resistor R107 are connected to the battery 10. The other end of the seventh resistor R107, the VDD pin of the touch chip U101, the AHLB pin of the touch chip U101, and the other end of the fourth capacitor C104 are connected.
[0074] In this embodiment, when the touch input terminal TH is touched by the user, a capacitance change is generated. This capacitance change is transmitted to one end of the fourth resistor R104, and then through its other end and one end of the third capacitor C103 to the IN pin (input pin) of the touch chip U101. The fourth resistor R104 and the third capacitor C103 work together to filter out unnecessary noise and stabilize the input signal. The fourth capacitor C104 can smooth power supply voltage fluctuations and ensure power supply stability. When the touch chip U101 detects a valid touch signal, it will send a corresponding signal through its QO pin (output pin). This signal is transmitted to the main control circuit 60 via the P13 terminal. The main control circuit 60 can perform specific operations based on the received signal, such as turning the disinfection function on / off, or starting / stopping wireless charging.
[0075] Please see Figure 2 In one embodiment of this utility model, the attitude detection circuit 30 includes:
[0076] The power supply terminal of the gyroscope circuit 31 is connected to the battery 10, and the signal output terminal of the gyroscope circuit 31 is connected to the main control circuit 60. The gyroscope circuit 31 is used to detect the placement angle of the disinfection box and output the corresponding angle detection signal.
[0077] The main control circuit 60 is used to control the operation of the disinfection circuit 20 according to the disinfection switch signal when the disinfection box is detected to be in an inverted position according to the angle detection signal.
[0078] Please see Figure 11 , Figure 11This is an electronic circuit diagram of the gyroscope circuit in one embodiment of the disinfection box circuit provided by this utility model. In this embodiment, the gyroscope circuit 31 can use an MPU-6050 chip to detect the placement angle of the disinfection box and control the operation of the disinfection circuit 20 based on the detection results. Upon startup, the main control circuit 60 can initialize the MPU6050, including configuring the communication interface and selecting parameters such as the measurement range (measurement range of the accelerometer and gyroscope), ensuring that the chip can work normally and accurately collect data. The 3-axis gyroscope and 3-axis accelerometer built into the MPU6050 begin to continuously monitor the position changes of the disinfection box. The gyroscope can detect changes in angular velocity, while the accelerometer can measure linear acceleration and the direction of gravity; the combination of these two can accurately calculate the attitude and angle information of the disinfection box. The MPU6050 chip integrates a digital motion processor to automatically perform attitude calculations, converting raw sensor data into easily understandable angle detection signals. When the main control circuit 60 detects that the disinfection box is in an inverted position based on the angle detection signal, for example, if the detected angle value is within a preset angle range, and the user triggers the disinfection switch signal, the main control circuit 60 can activate the disinfection circuit 20. Conversely, if the angle detection signal detects that the disinfection box is not in an inverted position, the disinfection process will not be initiated, thus ensuring safe use.
[0079] Please see Figure 2 In one embodiment of this utility model, the disinfection circuit 20 includes:
[0080] Light fixture 21 is used to generate the light source required for disinfection;
[0081] The boost power supply circuit 22 has its input terminal connected to the battery 10 and its output terminal connected to the first terminal of the lamp 21. The boost power supply circuit 22 is used to boost the voltage output by the battery 10 before outputting it.
[0082] The lamp driving circuit 23 has its first terminal connected to the second terminal of the lamp 21 and grounded. The controlled terminal of the lamp driving circuit 23 is connected to the main control circuit 60. The lamp driving circuit 23 is used to drive the lamp 21 to work according to the lamp driving signal output by the main control circuit 60.
[0083] Please see Figure 8 , Figure 8This is an electronic circuit diagram of a boost power supply circuit according to an embodiment of the disinfection box circuit provided by this utility model. In this embodiment, the boost power supply circuit 22 can use a TX9710 chip, which internally includes a PWM controller and a power MOSFET. It can achieve voltage boost conversion by controlling a network composed of inductor L2, diode D2, and capacitor C9. When the battery 10 is connected, the TX9710 chip starts working. Its internal PWM controller adjusts the duty cycle to control the switching frequency and time of the power MOSFET, thereby regulating the charging and discharging process of the inductor and achieving voltage increase. During each switching cycle, when the power MOSFET is turned on, current flows through the inductor and stores energy; when the MOSFET is turned off, the magnetic field energy in the inductor is released to capacitor C9 through the diode, simultaneously increasing the output voltage. The TX9710 chip is equipped with a feedback pin FB, which is used to monitor the output voltage and compare it with an internal reference voltage. If the output voltage is lower than the set value, the PWM controller adjusts the duty cycle so that more energy is transferred to the output terminal until the required voltage level is reached. The stable voltage after boost conversion is supplied to the first terminal of the lamp 21 through the output terminal of the boost power supply circuit 22, providing sufficient operating voltage for the lamp 21 to ensure that the lamp 21 can emit light normally and complete the disinfection task. The main control circuit 60 can be connected to the EN pin of the TX9710 chip to control the startup of the TX9710 chip.
[0084] Please see Figure 9 , Figure 9 This invention provides a lamp driving circuit and electronic circuit diagram for an embodiment of the disinfection box circuit. In this embodiment, lamp 21 (i.e. Figure 9 L1) includes UVC and UVA lamps. The UVC lamp is used for sterilization and disinfection, emitting short-wave ultraviolet light (200-280nm) that effectively destroys the DNA structure of microorganisms, achieving highly efficient disinfection. The UVA lamp emits longer-wavelength ultraviolet light (320-400nm), generating reactive oxygen species to assist the disinfection process. A bidirectional transient voltage suppressor (NC) is connected in parallel across the UVA lamp to protect it from transient overvoltage damage. The lamp drive circuit 23 may include a switching transistor Q4. When it is necessary to activate the UVC and / or UVA lamps, the main control circuit 60 can send a signal to turn on the switching transistor Q4, allowing current to flow through the UVC and UVA lamps, thus causing them to emit light.
[0085] Thus, in this embodiment, the light source can be emitted to disinfect the equipment to be disinfected through the coordinated operation of the boost power supply circuit 22, the lamp driving circuit 23 and the lamp 21.

In this embodiment, the battery 10 protection chip U6 has overcharge protection, over-discharge protection and overcurrent protection functions. When the voltage of the battery 10 is higher than a first preset voltage value during charging, the battery 10 protection chip can control the internal field-effect transistor MOSFET to turn off to stop charging; when the voltage of the battery 10 drops below a second preset voltage value during discharge under normal conditions, the battery 10 protection chip U6 can control the field-effect transistor MOSFET to turn off to stop discharging; when the discharge current is higher than a preset current value, the battery 10 protection chip U6 can control the field-effect transistor MOSFET to turn off to stop discharging. The battery protection chip U6 also detects the voltage of the battery 10 and outputs a corresponding voltage detection signal. The main control circuit 60 controls the wireless charging circuit 50 to stop working when the voltage of the battery 10 reaches a preset voltage threshold, i.e., when the battery 10 is fully charged. In this way, this embodiment enhances the safety of charging and discharging the battery 10.

In this embodiment, the voltage regulator circuit 90 includes a voltage regulator chip U5, which can regulate the voltage of the battery 10 to a voltage output of 3.3V. Since the voltage supplied by the battery 10 may vary depending on its charge level, the voltage regulator circuit 90 ensures that the voltage supplied to the main control circuit 60 and the attitude detection circuit 30 is a constant 3.3V regardless of the current charge level of the battery 10, thereby guaranteeing the stable operation of the circuit.
