As the public's awareness of disinfection continues to increase, disinfectant is expected to become a necessary household item, and household disinfectant manufacturing machines have great development potential.

[0003] Traditional household disinfectant manufacturing machines produce disinfectant by electrolyzing salt water. Specifically, when salt water (sodium chloride solution) is electrolyzed, chloride ions are oxidized to generate chlorine gas, which then reacts with water to generate hypochlorous acid, thereby obtaining the effective component of the disinfectant.

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is described more comprehensively below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] In one embodiment, a disinfectant manufacturing machine control device is provided to realize the control of the disinfectant manufacturing machine. The disinfectant manufacturing machine can be used as a household disinfectant manufacturing device, which is convenient for users to produce disinfectants at home for daily use, and is easy to use. The structure of the disinfectant manufacturing machine is not unique. Generally speaking, the disinfectant manufacturing machine includes an electrolysis module, an electric spraying system, a handle, a USB-TypeC data interface, a bottle, a display and controller, a trigger and a micro switch, and a battery. When working, the switch is located at the display and controller part, and the disinfectant manufacturing machine is turned on by the switch. There is also a disinfection button at the display and controller part. After pressing, the electrolysis module is controlled to electrolyze the brine. Pressing the trigger and the micro switch can spray disinfectant water from the electrolysis module. The USB-TypeC data interface can charge the battery. The battery is a storage battery that can store electricity, so that the disinfectant manufacturing machine can be used without plugging in.

[0027] The bottle contains sodium chloride solution. The principle of the electrolysis module to produce disinfectant includes: using the electrolysis module to electrolyze sodium chloride aqueous solution to generate sodium hypochlorite solution. Sodium hypochlorite is further decomposed by hydrolysis to form new ecological oxygen, which has extremely strong oxidizing properties and can denature proteins on bacteria and viruses (2NaCl+2H2O→electrolysis→Cl2↑+H2↑+2NaOH, Cl2+2NaOH→NaCl+H2O+NaClO, that is: NaCl+H2O→electrolysis→NaClO+H2↑). In the process of sterilization and virus killing, hypochlorous acid can not only act on cell walls and virus shells, but also penetrate into bacteria (viruses) and react with organic polymers such as bacterial (viral) proteins, nucleic acids and enzymes to kill pathogenic microorganisms; the chloride ions produced by hypochlorous acid can also significantly change the osmotic pressure of bacteria and viruses, causing their cells to lose activity and die; sodium hypochlorite can decompose trace amounts of pesticides remaining on agricultural and sideline products such as vegetables and fruits. Most pesticides are composed of organic matter, and the new oxygen released by sodium hypochlorite can oxidize and decompose these substances. Therefore, sodium hypochlorite has a strong disinfection ability, and the disinfectant produced by the disinfectant making machine can meet the daily needs of users.

[0028] In this example, see Figure 1The control device of the disinfectant manufacturing machine includes a temperature detector 100, a controller 200 and a switch tube 300. The temperature detector 100 is arranged on the mainboard of the disinfectant manufacturing machine. The temperature detector 100 is connected to the controller. The controller is connected to the control end of the switch tube 300. The input end of the switch tube 300 is used to access the power supply. The output end of the switch tube 300 is electrically connected to the mainboard. The temperature detector 100 can detect the mainboard temperature of the disinfectant manufacturing machine and send the mainboard temperature to the controller. The controller sends a corresponding control instruction to the switch tube 300 according to the comparison result between the mainboard temperature and the preset temperature threshold. The switch tube 300 adjusts its own conduction state according to the control instruction to make the mainboard powered or powered off. The temperature detector 100 is used to monitor the temperature of the mainboard. When the temperature of the mainboard is abnormal, the mainboard can be controlled to disconnect the power supply and stop working, thereby avoiding poor working performance caused by the mainboard temperature being too high and still running, extending the service life of the mainboard, improving the safety performance of the disinfectant manufacturing machine, and thus improving the reliability of the disinfectant manufacturing machine.

[0029] In the present embodiment, the mainboard refers to a circuit board for controlling the operation of each device of the disinfectant manufacturing machine, and the circuit board is arranged in the housing of the disinfectant manufacturing machine to reduce the damage of the external environment. The size and quantity of the mainboard are not unique. According to the number of components of the disinfectant manufacturing machine and the difference in the functions to be realized, the size of the mainboard can be adjusted as needed. In order to better realize the control of the disinfectant manufacturing machine, the mainboard can also be dispersed into several pieces, which are arranged in different positions respectively, simplifying the design difficulty of the disinfectant manufacturing machine. Each dispersed mainboard can be interconnected, which is convenient for communication and improves the intelligent degree of the disinfectant manufacturing machine.

[0030] Specifically, the temperature detector 100 is arranged on the mainboard of the disinfectant manufacturing machine and connected to the controller, and can detect the mainboard temperature of the disinfectant manufacturing machine and send the mainboard temperature to the controller. The setting position of the temperature detector 100 on the mainboard is not unique. For example, it can be set in the area with the highest temperature rise of the mainboard. When the temperature detector 100 is set in the area with the highest temperature rise of the mainboard, if the temperature of the area with the highest temperature rise of the mainboard is greater than the preset temperature threshold, it is judged that the entire mainboard is in danger of overheating, and the temperature warning state can be entered early to avoid further damage caused by the excessive temperature of the mainboard. The method of obtaining the position of the area with the highest temperature rise of the mainboard is not unique. For example, a thermometer can be used to detect the temperature of each area of ​​the mainboard. When the mainboard is running at the highest power, the area with the highest temperature can be used as the area with the highest temperature rise of the mainboard. Alternatively, it can also be considered that according to the working state of the disinfectant manufacturing machine, an area that may be the area with the highest temperature rise of the mainboard is selected as a temperature measurement point, or a temperature measurement point is set according to other requirements, and the temperature detector 100 is set to measure the temperature to realize the monitoring of the mainboard temperature. The type of temperature detector 100 is not unique. In this embodiment, the temperature detector 100 may be a thermistor temperature sensor. Thermistor temperature sensors are low in cost and simple to use. As the temperature detector 100, the disinfectant making machine can be more convenient to use. It is understood that in other embodiments, the temperature detector 100 may be other types of devices as long as those skilled in the art consider it feasible.

[0031] The controller can use the controller that already exists in the disinfectant manufacturing machine, add the instructions that need to be executed by the disinfectant manufacturing machine control device to the original controller, and connect the switch tube 300 through different ports on the basis of the original controller, which can reduce the hardware cost. It is also possible to use an independent controller different from the original controller to avoid sharing a controller to cause excessive load and affect work efficiency. The type of controller is not unique, and can be CPLD (Complex Programmable Logic Device), FPGA (Field-Programmable Gate Array) or single-chip microcomputer. CPLD as a controller has the advantages of flexible programming, high integration, short design and development cycle, wide application range, low design and manufacturing cost, strong confidentiality, popular price, etc., and fast speed, with greater time predictability. FPGA as a controller can realize parallel task processing in the true sense, and does not use an operating system. There is deterministic hardware for each task, low design cost, and high working stability. The single-chip microcomputer as a controller integrates various functional components on one chip, adopts a bus structure internally, reduces the connection between the chips, greatly improves the reliability and anti-interference ability of the single-chip microcomputer, and thus has the advantages of small size, simple structure and high reliability. It can be understood that in other embodiments, the controller can also be other types of devices as long as those skilled in the art believe that it can be implemented.

[0032] The preset temperature threshold value can be a value pre-set in the controller, for example, a value that has been set when the disinfectant manufacturing machine leaves the factory, or a value that is updated by the user according to the needs during the user's use later. The disinfectant manufacturing machine control device can also include an input device, which is connected to the controller 200, and the user can set the temperature threshold value through the input device. The input device sends the received user-set temperature threshold value to the controller, and the controller updates the existing preset temperature threshold value to achieve the on-demand setting of the temperature threshold value. The types of input devices include but are not limited to buttons, touch screens, or voice input devices. The value of the preset temperature threshold value is not unique and can be set according to actual needs.

[0033] The type of control instruction is not unique, and can generally be a high level or a low level. The level sent is different according to the comparison result between the temperature of the mainboard and the preset temperature threshold. The control end of the switch tube 300 is connected to the controller to receive the control instruction sent by the controller. According to the difference of the high level or low level received, the conduction state of the switch tube 300 is different. The input end of the switch tube 300 is used to access the power supply, and the output end of the switch tube 300 is electrically connected to the mainboard. When the switch tube 300 is turned on, the input end and the output end are connected, the mainboard is powered, and can work normally. When the switch tube 300 is turned off, the input end and the output end are disconnected, the mainboard cannot obtain power, and the mainboard stops working. The type of the switch tube 300 is not unique, for example, it can be an NPN transistor, the base of the NPN transistor is connected to the controller, the collector is used to access the power supply, and the emitter is grounded. When the base of the NPN transistor receives the control instruction and the current of the base and the collector meets the conduction condition, the NPN transistor is turned on, and the mainboard can be powered normally. It can be understood that in other embodiments, the switch tube 300 can also be other types of devices as long as those skilled in the art consider it feasible.

[0034] Expandably, the disinfectant manufacturing machine control device can also be set on the existing motherboard as a small part of the disinfectant manufacturing machine mainboard circuit. Different circuits control different parts. The disinfectant manufacturing machine control device is connected to the main chip on the original circuit board. The main chip obtains the ambient temperature through the disinfectant manufacturing machine control device. If the main chip determines that the temperature is too high, the power supply is cut off.

[0035] In one embodiment, see Figure 2 The disinfectant manufacturing machine control device also includes a current limiting device 400, and the temperature detector 100 is connected to the controller through the current limiting device 400. The current limiting device 400 can limit the current flowing into the controller, avoid the impact of excessive current on the controller, protect the controller, and extend the service life of the controller.

[0036] Specifically, the type of current limiting device 400 is not unique. In the present embodiment, the current limiting device 400 may be a current limiting resistor. The current limiting resistor has a low cost, a wide range of applications, and a good current limiting effect. As a current limiting device 400, the performance of the disinfectant manufacturing machine can be improved. The current limiting resistor is connected in series with the temperature detector 100 and the controller. For example, the temperature detector 100 is a thermistor. One end of the thermistor is used to access the power supply, and the other end is connected to the current limiting resistor. The end of the current limiting resistor that is not connected to the temperature detector 100 is connected to the controller. In this way, the electric energy connected to the temperature detector 100 is consumed by the current limiting resistor and then transmitted to the controller, thereby protecting the controller. It can be understood that in other embodiments, the current limiting device 400 may also be other types of devices, as long as those skilled in the art believe that it can be implemented.

[0037] In one embodiment, see Figure 2 The disinfectant manufacturing machine control device also includes a voltage divider 500, one end of which is connected to the common end of the temperature detector 100 and the controller, and the other end is grounded. The voltage divider 500 is connected to the temperature detector 100 to play a voltage dividing role. The voltage divider 500 is connected to the controller, and the controller can determine the mainboard temperature by detecting the pressure of the voltage divider 500, which is convenient to use.

[0038] Specifically, the type of the voltage divider device 500 is not unique, for example, it can be a voltage divider resistor. One end of the voltage divider resistor is connected to the common end of the temperature detector 100 and the controller, and the other end is grounded. Taking the temperature detector 100 as a thermistor as an example, one end of the thermistor is used to access the power supply, and the other end is directly connected to the controller or connected to the controller through a current limiting resistor. The voltage divider resistor connects the common end of the thermistor and the voltage divider resistor, and the other end of the voltage divider resistor is grounded, and the voltage divider resistor is connected in series with the thermistor. When the ion concentration in the water is too high, the temperature of the mainboard also rises sharply. At this time, the resistance value of the thermistor changes, and the voltage of the voltage divider resistor also changes. The controller detects the voltage of R1, and it is known that the resistance and voltage of the thermistor at this time, thereby analyzing the mainboard temperature detected by the thermistor. Once the thermistor temperature reaches the preset temperature threshold, the controller controls the switch 800 tube 300 to disconnect, the mainboard is powered off, and the disinfectant manufacturing machine stops working. It can be understood that in other embodiments, the voltage divider device 500 can also be other types of devices, as long as those skilled in the art think that it can be achieved.

[0039] In one embodiment, see Figure 2 The disinfectant manufacturing machine control device also includes a filter circuit 600, one end of the filter circuit 600 is connected to the common end of the temperature detector 100 and the controller 200, and the other end is grounded. The filter circuit 600 can filter out clutter in the circuit and improve the working performance of the disinfectant manufacturing machine control device.

[0040] Specifically, the structure of the filter circuit 600 is not unique. Taking the temperature detector 100 as a thermistor, the disinfectant manufacturing machine control device also includes a current limiting resistor and a voltage dividing resistor as an example. One end of the thermistor is used to access the power supply, and the other end is connected to the controller through the current limiting resistor. The voltage dividing resistor connects the common end of the thermistor and the voltage dividing resistor, and the other end of the voltage dividing resistor is grounded. The voltage dividing resistor is connected in series with the thermistor. The filter circuit 600 includes a first capacitor, a second capacitor and a third capacitor. The first capacitor and the second capacitor are connected in parallel to form a parallel first end and a parallel second end. The common end of the thermistor, the current limiting resistor and the voltage dividing resistor is connected to the parallel first end, and the parallel first end is grounded. The common end of the current limiting resistor and the controller is connected to the third capacitor and one end, and the other end of the third capacitor is grounded. In actual work, in actual work, the controller detects the AD value of the voltage dividing resistor. If the AD value is too disturbed and there is a large fluctuation, the disturbance can be reduced by the filter circuit 600, which is conducive to improving the working performance of the disinfectant manufacturing machine control device. It can be understood that in other embodiments, the filter circuit 600 can also adopt other structures as long as those skilled in the art believe that it can be achieved.

[0041] In one embodiment, see Figure 2 The disinfectant manufacturing machine control device also includes a DC boost circuit 700, the first end of the DC boost circuit 700 is used to access the power supply, and the second end of the DC boost circuit 700 is connected to the controller. The DC boost circuit 700 is a type of DC / DC circuit, which generates low-voltage pulses through high-frequency oscillation, and then the pulse transformer boosts the voltage to a predetermined voltage value, and then obtains high-voltage direct current through pulse rectification. The voltage of the power supply can be increased to the required voltage value for use by the controller, ensuring the normal operation of the controller and improving the working performance of the controller. In this embodiment, the DC boost circuit 700 can stabilize the voltage at about 5V, so that the controller can work normally.

[0042] In one embodiment, see Figure 2 The disinfectant manufacturing machine control device also includes a control switch 800, a control end of the control switch 800 is connected to the input end of the switch tube 300, a first end of the control switch 800 is used to connect to the power supply, and a second end of the control switch 800 is connected to the first end of the DC boost circuit 700.

[0043] The control end of the control switch 800 is connected to the input end of the switch tube 300. The conduction state of the control switch 800 is different according to whether the input end of the switch tube 300 is high or low. The first end of the control switch 800 is used to connect to the access power supply, and the second end of the control switch 800 is connected to the first end of the DC boost circuit 700. When the control switch 800 is turned on, the first end and the second end are turned on, and the current of the access power supply flows to the DC boost circuit 700, and then transmitted to the controller, so that the controller works normally. When the control switch 800 is turned off, the first end and the second end are disconnected, and the controller cannot obtain electrical energy. The type of the control switch 800 is not unique, for example, it can be a P-channel MOS tube or a PNP transistor, etc., as long as those skilled in the art believe that it can be implemented.

[0044] In one embodiment, the disinfectant manufacturing machine control device also includes a first regulating resistor and a second regulating resistor, and the first end of the control switch 800 is connected to the control end of the control switch 800 through the first regulating resistor, and the control end of the control switch 800 is connected to the input end of the switch tube 300 through the second regulating resistor. The first regulating resistor and the second regulating resistor both play the role of voltage division, which can adjust the conduction state of the control switch 800 and improve the working performance of the control switch 800. When the ratio of the voltage on the first regulating resistor and the second regulating resistor reaches the conduction condition of the control switch 800, the control switch 800 is turned on, and the current flows to the DC boost circuit 700, and then transmitted to the controller, so that the controller works normally. The values ​​of the first regulating resistor and the second regulating resistor are not unique, and a suitable resistance value can be selected according to actual needs, as long as those skilled in the art believe that it can be achieved.

[0045] In one embodiment, the disinfectant manufacturing machine control device also includes a third regulating resistor and a fourth regulating resistor. The control end of the switch tube 300 is connected to the output end of the switch tube 300 through the third regulating resistor, and the control end of the switch tube 300 is connected to the controller through the fourth regulating resistor. The third regulating resistor is a pull-down resistor of the switch tube 300, and the fourth regulating resistor is a resistor that acts as a current limiter. When the current of the third regulating resistor and the fourth regulating resistor reaches the turn-on current condition of the switch tube 300, the switch tube 300 is turned on, the mainboard is connected to the power supply, and the disinfectant manufacturing machine works normally. The values ​​of the third regulating resistor and the fourth regulating resistor are not unique, and appropriate resistance values ​​can be selected according to actual needs, as long as those skilled in the art believe that it can be achieved.

[0046] In one embodiment, the temperature detector 100 is a thermistor, which is arranged on the mainboard, one end of the thermistor is used to access the power supply, and the other end is connected to the controller. The thermistor has different resistance values ​​according to the change of the mainboard temperature, and the resistance value of the thermistor can reflect the temperature of the mainboard. Further, when the thermistor is connected to a voltage divider resistor, the resistance value of the thermistor can be calculated by detecting the voltage value of the voltage divider resistor, thereby realizing the detection of the mainboard temperature. The thermistor as a temperature detector 100 is low in cost and simple to use. As a temperature detector 100, it can improve the convenience of use of the disinfectant manufacturing machine.

[0047] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. The working principle of the disinfectant manufacturing machine is: sodium hypochlorite solution is generated by electrolyzing sodium chloride aqueous solution. Sodium hypochlorite is further decomposed by hydrolysis to form new ecological oxygen, which has extremely strong oxidizing properties and can denature proteins on bacteria and viruses (2NaCl+2H2O→electrolysis→Cl2↑+H2↑+2NaOH, Cl2+2NaOH→NaCl+H2O+NaClO, that is: NaCl+H2O→electrolysis→NaClO+H2↑). In the process of sterilization and virus killing, hypochlorous acid can not only act on cell walls and virus shells, but also penetrate into bacteria (viruses) and react with organic macromolecules such as bacterial (viral) proteins, nucleic acids and enzymes to kill pathogenic microorganisms; the chloride ions produced by hypochlorous acid can also significantly change the osmotic pressure of bacteria and viruses, causing their cells to lose activity and die; sodium hypochlorite can decompose trace amounts of pesticides remaining on agricultural and sideline products such as vegetables and fruits. The vast majority of pesticides are composed of organic matter, and the new oxygen released by sodium hypochlorite can oxidize and decompose these substances.

[0048] In one embodiment, see Figure 3 , the temperature detector 100 is a thermistor, the controller 200 is an MCU, the switch tube 300 is a transistor Q1, the current limiting device 400 is a resistor R2, the voltage divider device 500 is a resistor R1, the filter circuit 600 includes capacitors C1, C2 and C3, the DC boost circuit 700 is a DC-DC, the control switch 800 is a MOS tube U1, the first adjustment resistor is a resistor R3, the second adjustment resistor is a resistor R4, the third adjustment resistor is a resistor R5, and the fourth adjustment resistor is a resistor R6. When the temperature of the mainboard of the disinfectant manufacturing machine is too high, the resistance value of the thermistor changes, and the MCU can detect the current voltage value in time and calculate the temperature of the mainboard at this time. If the set temperature threshold and the preset temperature threshold are reached, the safety measure of cutting off the power supply will be implemented.

[0049] Specifically, VCC is the power supply for the disinfectant manufacturing machine, the thermistor is an NTC resistor. When the temperature of the mainboard is higher, the resistance is smaller. R2 is a resistor that limits the flow into the chip and plays a role in protecting the chip. C1, C2, and C3 are filter capacitors that play a filtering role. R1 is connected in series with the thermistor to play a voltage divider role. U1 is a MOS tube that plays a switch role. R3 and R4 are voltage divider resistors. When R3:R4 meets the requirements of U1, U1 is turned on and the current flows to the DC-DC. The DC-DC is a DC boost circuit 700 that stabilizes the voltage at 5V. R6 is a current limiting resistor. When its current reaches the turn-on current of the Q1 transistor, Q1 is turned on. Q1 reaches the IBβ≥IC condition, and Q1 is turned on. R5 is a pull-down resistor. The thermistor is installed at the highest temperature part of the mainboard. A thermometer can be used to measure the highest temperature point when the mainboard is at the highest power. The controller determines the mainboard temperature by detecting the voltage of R1. C1 and C2 capacitors can be removed according to the actual design. In actual work, the MCU is tested to detect the AD value of R1. If the AD value has too much interference and fluctuates greatly, C1 and C2 need to be installed. U1 is a P-channel MOS tube and can be replaced by a PNP transistor.

[0050] Please refer to the control flow chart of the disinfectant manufacturing machine control device Figure 4 The disinfectant making machine controls its power supply through Q1. When Q1 is turned on, the disinfectant making machine is in working state. The temperature measurement circuit is a thermistor installed on the mainboard. Its installation position is the area with the highest temperature rise of the mainboard. When electrolyzing salt water, when the ion concentration in the water is too high, the temperature of the mainboard also rises sharply. At this time, the resistance value of the thermistor changes. The MCU detects the voltage of R1 to know the temperature of the thermistor at this time. Once the temperature of the thermistor reaches the threshold set by the MCU, the MCU controls Q1 to disconnect, the mainboard is powered off, and the disinfectant making machine stops working. Use thermistors to measure the temperature of the mainboard to protect the mainboard of the disinfectant making machine. When the mainboard temperature is detected to be too high, the electrolysis will also be terminated to improve overall safety.
