Description

Technical Field

[0001] This invention relates to the field of virus disinfection technology, and more specifically to a portable active oxygen disinfection device and its control method. Background Technology

[0002] With increasing public health awareness and growing environmental protection demands, efficient and environmentally friendly sterilization and disinfection technologies have become a focus of attention across society. Reactive oxygen species (ROS), with their unique strong oxidizing properties and broad-spectrum bactericidal characteristics, have demonstrated enormous application potential in various fields such as medical and health care, food safety, and water treatment. ROS molecules, including ozone, superoxide anion radicals, hydroxyl groups, and hydrogen peroxide, are all in a highly active excited state, capable of rapidly destroying the cellular structure of bacteria and viruses, achieving rapid and effective sterilization and disinfection.

[0003] Currently, proton exchange membrane (PEM) hydrolysis of reactive oxygen species (ROS) is a relatively mature method for ROS preparation. This technology, through low-pressure water electrolysis with the assistance of a proton exchange membrane, can stably generate a mixed gas containing various ROS components. However, this technology has a significant drawback: it is extremely sensitive to water quality, requiring the use of pure water as the electrolysis medium. This requirement not only increases production costs but also limits its application in areas with poor water quality or scarce resources. More seriously, impurities in non-pure water environments can rapidly deposit and clog the micropores of the proton exchange membrane, even causing corrosion of the membrane material, thus severely shortening its lifespan, increasing maintenance costs, and potentially causing secondary environmental pollution. Summary of the Invention

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A portable active oxygen disinfection device includes: a water tank, a protective upper shell, and a lower shell. The protective upper shell is fixedly installed on the water tank, and the lower shell is fixedly installed below the water tank. The protective upper shell is detachable.

A thin-film pressure sensor and a temperature sensor are provided inside the water tank. The thin-film pressure sensor measures the water level in the tank, and the temperature sensor measures the water temperature. A control board and a battery are provided inside the lower shell. Buttons are provided on the side wall of the lower shell. The control board is connected to the buttons, battery, thin-film pressure sensor, temperature sensor, and active oxygen electrolysis cathode and anode plates.

[0007] Furthermore, the control board is equipped with a light indicator module and an MCU.

[0018] When the battery is in the charging state, determine whether the real-time power level is greater than the power level of the second battery.

[0019] If the real-time battery level is greater than the second battery level, the MCU controls the battery to stop charging and uses an indicator light module to display the current real-time battery level.

[0020] Furthermore, the preset reference current includes the operating current of the first electrode and the operating current of the second electrode, wherein the operating current of the first electrode is less than the operating current of the second electrode.

[0038] Furthermore, the determination of the second working time point T2 based on the first working time point T1 and the active oxygen preparation time is specifically as follows:

[0039] The second working time point T2 is calculated using the formula T2=T1+OL, where OL is the preparation time of active oxygen.

[0040] Furthermore, the determination of the third working time point T3 based on the second working time point T2 and the effective duration of active oxygen disinfection is specifically as follows:

[0053] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0054] like Figure 1 The portable active oxygen disinfection device shown includes: a water tank 2, a protective upper shell 1, and a lower shell 4. The protective upper shell 1 is fixedly installed on the water tank 2, and the lower shell 4 is fixedly installed below the water tank 2. The protective upper shell 1 is a detachable shell and can be disassembled; the user needs to remove the protective upper shell 1 for use and reinstall it afterward. The lower shell 4 is used to carry the internal components of the portable active oxygen disinfection device and is connected to the water tank 2 but cannot be disassembled. The water tank 2 is used to hold clean water or an active oxygen solution.

[0055] The bottom of water tank 2 is equipped with active oxygen electrolysis cathode and anode electrodes 6. These electrodes electrolyze clean water to generate active oxygen, which is then used to electrolyze the water in water tank 2 to produce an active oxygen aqueous solution. A sprayer 5 is installed inside the protective upper shell 1, fixedly mounted on the top of water tank 2, and used to spray the active oxygen aqueous solution from water tank 2 onto the area to be disinfected. In use, the user can manually press the nozzle to spray the active oxygen aqueous solution from water tank 2 onto the area to be disinfected.

[0056] The water tank 2 is equipped with a thin-film pressure sensor 10 and a temperature sensor 11. The thin-film pressure sensor 10 is used to measure the water level in the tank, and the temperature sensor 11 is used to measure the water temperature. The lower casing 4 houses a control board 7, a battery 8, and a charging interface 9. A button 3 is located on the side wall of the lower casing 4. The control board 7 includes a light indicator module 12 and an MCU 13. Users can change the operating status of the portable active oxygen disinfection device by pressing the button 3. The battery 8 serves as the power source for the portable active oxygen disinfection device, and the charging interface 9 uses a Type-C interface.

[0057] like Figure 2 As shown, the MCU13 is connected to the light indicator module 12, button 3, battery 8, thin-film pressure sensor 10, temperature sensor 11, and active oxygen electrolysis anode and cathode plates 6, respectively. It is used to obtain control signals through button 3, and to control the charging and discharging of battery 8, drive and monitor the status of active oxygen electrolysis anode and cathode plates 6, and monitor the liquid level in water tank 2 according to the control signals. It generates corresponding status indication signals according to the monitoring information and displays them on the light indicator module 12.

[0058] Accordingly, based on the aforementioned portable active oxygen disinfection device, such as Figure 3 As shown, the present invention also discloses a control method for a portable active oxygen disinfection device, which specifically includes the following steps:

[0059] S1: Monitors the battery level and operating status in real time, compares the battery level with a preset benchmark level, and controls the battery operation based on the comparison results.

[0060] In a specific implementation, the preset baseline power level includes the power level of a first battery and the power level of a second battery, wherein the power level of the first battery is less than the power level of the second battery.

[0061] This step provides a battery operation control strategy, the specific process of which is as follows:

[0062] First, the system collects real-time battery power and operating status data, and then uses a light indicator module to visually display this information to the user via digital display or light indicators. The battery operating status includes charging and discharging states.

[0063] Then, it is determined whether the real-time battery level is lower than the first battery level. If the real-time battery level is lower than the first battery level, the MCU disconnects the load from the battery, causing the portable active oxygen disinfection device to automatically shut down, preventing the battery from being over-discharged and shortening its lifespan.

[0064] When the battery is in the charging state, it is determined whether the real-time battery level is greater than that of the second battery. If the real-time battery level is greater than that of the second battery, the MCU controls the battery to stop charging and uses an indicator light module to display the current real-time battery level to the user in a visual way through digital display or light indication, so as to prevent the battery from being overcharged.

[0065] S2: Monitor the working current of the active oxygen electrolysis cathode and anode plates in real time, compare the current with a preset reference current, identify the abnormal state of the active oxygen electrolysis cathode and anode plates based on the comparison result, and display the abnormal information.

[0066] In a specific implementation, the preset reference current includes the operating current of the first electrode and the operating current of the second electrode, wherein the operating current of the first electrode is less than the operating current of the second electrode. The operating current of the first electrode is the minimum operating current of the active oxygen electrolysis cathode and anode electrodes, and the operating current of the second electrode is the maximum operating current of the active oxygen electrolysis cathode and anode electrodes.

[0067] This step provides a strategy for controlling the operation of active oxygen electrolysis cathode and anode electrodes. The specific process is as follows:

[0068] First, the real-time operating current of the active oxygen electrolysis cathode and anode plates was collected;

[0069] Then, it is determined whether the real-time operating current is less than the operating current of the first electrode. If so, the working status of the active oxygen electrolysis anode and cathode electrodes is determined to be abnormal, which means two possibilities: one is that there is no water in the disinfection device's water tank; the other is that the anode and cathode electrodes of the disinfection device are open-circuited. Both of these abnormal situations can generate alarm information, which is intuitively displayed to the user through digital display or light indication using the light prompt module.

[0070] If the real-time operating current is greater than or equal to the operating current of the first electrode, then it is determined whether the real-time operating current is greater than the operating current of the second electrode. If so, it means that the anode and cathode electrodes are short-circuited. At this time, it is determined that the working status of the active oxygen electrolysis anode and cathode electrodes is abnormal. The MCU immediately sends a control signal to shut down the machine, generates an alarm message, and uses an indicator module to intuitively display the information to the user through digital display or light indication, so as to facilitate contacting professional repair personnel.

[0071] S3: Real-time monitoring of water tank level, water tank temperature, and the operating status of the portable active oxygen disinfection device.

[0072] In a specific implementation, a thin-film pressure sensor monitors the water level in the tank in real time, a temperature sensor monitors the water temperature in the tank in real time, and an MCU acquires the operating status information of the portable active oxygen disinfection device. Based on the determined final active oxygen concentration, the water level in the tank determines the preparation time; during the standby period of the disinfection device, the water temperature in the tank determines the half-life of the active oxygen.

[0073] S4: In response to the activation signal of the portable active oxygen disinfection device triggered by the button, determine the operating status switching time point of the portable active oxygen disinfection device according to the operating status information, water tank level, and water tank temperature, and control the operation of the portable active oxygen disinfection device according to the operating status switching time point.

[0074] In a specific implementation, the specific process of this step is as follows:

[0075] In response to the activation signal of the portable active oxygen disinfection device triggered by the button, the current time point is recorded as the first working time point T1. It should be noted that this process has a first working time point T1, a second working time point T2, and a third working time point T3. T1 < T2 < T3; the first working time point T1 is the time point when the disinfection device is triggered by the button, and the disinfection device is activated when the button is pressed in the off state.

[0076] First, confirm the water level in the tank. Based on the water level, determine the active oxygen preparation time. Then, based on the first working time point T1 and the active oxygen preparation time, determine the second working time point T2 and send a start signal to the active oxygen electrolysis cathode and anode plates to begin active oxygen preparation. Specifically, the second working time point T2 is calculated using the formula T2 = T1 + OL, where OL is the active oxygen preparation time, which is mainly affected by the water level in the tank.

[0077] Then, the current time is collected in real time to determine whether the current time has reached the second working time point T2. If so, a shutdown signal is sent to the active oxygen electrolysis anode and cathode plates, and the device enters standby mode. When the disinfection device reaches the second working time point, it switches to standby mode and stops active oxygen production. It should be noted that if the customer triggers the button again before reaching the second working time point, the disinfection device will stop production, shut down, and enter sleep mode. In addition, before reaching the second working time point, the battery operation control strategy and active oxygen electrolysis anode and cathode plate operation control strategy disclosed in steps S1 and S2 must be continuously used to identify and control anomalies in real time. If an anomaly is identified, operation is stopped immediately.

[0078] At this point, the water temperature in the tank is collected. Based on the water temperature, the effective duration of the active oxygen disinfection effect is determined. The third working time point T3 is then determined based on the second working time point T2 and the effective duration of the active oxygen disinfection effect. Specifically, the third working time point T3 is calculated using the formula T3 = T2 + XL, where XL is the effective duration of the active oxygen disinfection effect, which is primarily affected by the water tank temperature.

[0079] Once the third working time point T3 is determined, the water temperature in the tank is collected in real time, and the third working time point T3 is corrected based on the real-time water temperature. Specifically, the water temperature in the tank is collected in real time, and the corresponding active oxygen half-life HL is obtained from the active oxygen half-life reference table based on the water level in the tank; finally, the third working time point T3 is corrected using the formula T3 = T2 + HL.

[0080] Finally, the current time is collected in real time to determine whether the current time has reached the third working time point T3; if so, the portable active oxygen disinfection device is shut down and put into sleep mode via the MCU.

[0081] It should be noted that if the customer does not perform any other operations during the standby period, the disinfection device will shut down and enter sleep mode after reaching the third working time point T3; if the customer triggers the button again during the standby period, the disinfection device will need to consider the degree of active oxygen decay and the water level in the tank to confirm the second working time point T2 before restarting the preparation of active oxygen.

[0082] In this invention, the buttons can be in the form of touch, light touch, etc., and the button triggering methods can be single click, double click, long press, etc.

[0083] As an example, based on the control method of the aforementioned portable active oxygen disinfection device, this patent embodiment discloses an active oxygen preparation process for a portable active oxygen disinfection device, taking a single-click triggering method for the button and a tri-color light indicator module as an example. Figure 4 As shown, the specific process is as follows:

[0084] 1. Click the micro switch to power on the positive and negative electrode plates, provided that the water level and temperature in the water tank are normal. The three-color light will flash blue until the second working time point is reached.

[0085] 2. Within the time frame shorter than the second working time point, the system will monitor the working current of the positive and negative electrodes, the water level in the tank, and other statuses in real time. Based on the status of each functional component of the disinfection device, corresponding lighting effects will be displayed to the user. Specifically, a red light will illuminate when a component malfunctions, and a yellow light will illuminate when the water tank is empty or low on water.

[0086] 3. After reaching the second working time point, the positive and negative electrode plates are de-energized, the three-color light switches to a solid blue light, and the water tank level and water temperature are obtained in real time. The third working time point is then corrected in real time using the aforementioned formula.

[0087] 4. If the button is triggered again within the time range of the third working time point, the second working time point will be adjusted according to the water tank level and the residual concentration of active oxygen, and the process 1-3 will be executed again.

[0088] 5. After reaching the third working time point, the standby ends, the disinfection device shuts down and enters sleep mode.

[0089] Therefore, this invention discloses a portable active oxygen disinfection device and its control method, which can generate active oxygen using tap water through electrolytic active oxygen generation technology.

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.
