[0057] Each connecting cable inside the housing 1 is preferably made of a material that is resistant to high voltage corrosion to prevent the high voltage from damaging the circuit.

[0058] In addition, the air inlet 2 and the air outlet 3 are arranged on the housing 1, and the control panel 4 is arranged on the front side of the housing 1. Among them, a filter screen 12 is arranged at the air inlet 2, and the filter screen 12 is preferably made of activated carbon material to filter and purify the incoming air and remove large particles of impurities and dust in the air; the air outlet protective cover 11 arranged between the rotating blades 6 of the air outlet 3 and the discharge needle plate 7 is a metal mesh structure, which plays a role of blocking and protecting, and prevents the negative oxygen ions generated after the high-voltage ionization of the air from flowing back through the air outlet, thereby causing damage to the inside of the disinfection machine housing 1.

[0059] The control panel 4 is located between the two air outlets 3, and the control panel 4 includes a display screen and control buttons; the control panel 4 is inside the remote control receiving device.

Figure 6 The remote control module is the remote control receiving device.

[0062] Specifically, the main control chip device includes: a main control chip, the main control chip is used to control the indicator light control device and the fan control device; and transmit information with the remote control receiving device.

[0063] The indicator light control device comprises: an indicator light, wherein the indicator light is used to display whether the fan control device is in a working state. If so, the indicator light is on, and if not, the indicator light is off.

[0064] The indicator light control device is Figure 4 The disinfection lamp control device shown in FIG. 1 may include an indicator light as shown in FIG. Figure 6 LED1, LED2 and LED3 are shown.

[0065] The fan control device comprises: a plurality of air inlets, a plurality of air outlets, a rotating blade 6 arranged at each of the air outlets, a discharge needle plate 7 arranged in front of the rotating blades, and a discharge needle 14 arranged on the discharge needle plate.

[0066] The air inlet is an inlet for air to enter. In the embodiment of the present application, air enters the plasma sterilizer through the air inlet.

[0067] The discharge needle is used to ionize the air to achieve air disinfection and purification operations.

[0068] In the air disinfection and purification process of the embodiment of the present application, a high voltage is applied to the discharge needle 14 to discharge, so that the air undergoes an ionization reaction to generate negative oxygen ions, thereby completing the air purification operation.

[0069] The rotating blades are mainly used for rotating and extracting or discharging air.

[0070] The air outlet is used as an outlet for discharging air after the air disinfection and purification operation.

[0071] The fan part of the embodiment of the present application has an air outlet as follows: Fig. 9 As shown. Through the air outlet, the negative oxygen ions generated by the ionization of the air inside the plasma disinfection machine can be discharged from the inside of the plasma disinfection machine.

[0072] In a possible implementation manner, the control circuit board module further includes:

[0073] The display output device is connected to the main control chip device, and has a digital tube or other display device in the display output device, which is used to display the indication information and the air purification information through the digital tube or other display device. The indication information is whether the indicator light is on, and the air purification information is the concentration of negative oxygen ions.

[0074] In a possible implementation manner, the control circuit board module further includes:

[0076] A high-voltage package control device, through which the power supply device is connected to the indicator light control device and the fan control device, is used for high-voltage package output to control the high voltage of the indicator light control device and the fan control device. For example, during the air disinfection and purification process, the high-voltage package control device can independently control the operation of applying a high voltage to the discharge needle 14 for discharge, and at the same time, the high-voltage control device independently controls the operation of applying a high voltage to the indicator light so that the indicator light lights up, so as to display that the fan control device is in working state through the indicator light.

[0077] An Internet of Things device, connected to each device in the control circuit board module, for controlling the connection inside the control circuit board module; Figure 4 and Figure 6 The Internet of Things module is the Internet of Things device.

[0078] The power supply device is connected to each device in the control circuit board module. The power supply device includes a power interface 5 inside, through which power is supplied to each device structure in the control circuit board module.

[0079] In an embodiment of the present application, each device in the control circuit board module individually controls (i.e., separately controls) the indicator light control device and the fan control device according to actual conditions. For example, it can individually control the rotation frequency of the rotating blades 6 in the fan control device, thereby achieving control of the air extraction and exhaust rate.

[0080] In the embodiment of the present application, each device in the control circuit board module controls each external structure individually (i.e., controls them separately) according to the actual situation; the external structure is a boost power module and an electromagnetic coil module. The boost power module is used to boost the voltage of the control circuit board module; the electromagnetic coil module is used to ensure the stability of the boost control of the boost power module.

[0081] Specifically, the control circuit board module is connected to the electromagnetic coil 13 in the electromagnetic coil module, and the boost power supply 9 in the boost power supply module is controlled separately by the high-voltage package control device and the electromagnetic coil 13 in the control circuit board module, so as to realize the subsequent control of the discharge voltage and frequency of the discharge needle 14. The boost power supply 9 controls the voltage of the discharge needle 14 on the discharge needle plate 7, so that the discharge voltage of the discharge needle 14 can reach up to 12,000 volts, thereby ensuring the efficiency of air ionization.

[0082] The electromagnetic coil 13 can ensure the stable increase of the voltage of the boost power supply 9, so that the discharge needle 14 on the discharge needle plate 7 can discharge stably, ensuring that it can discharge smoothly during the ionization process, thereby improving the overall discharge efficiency and air purification efficiency.

[0083] The boost power supply schematic is as follows: Figure 7 As shown. Connect the 220V power supply, first rectify it into DC, then enter the switch tube and the primary transformer, form an oscillation circuit to boost the voltage, and then boost it through the secondary transformer, the voltage reaches 2400V, and finally boost it to high voltage 5 times through the voltage doubling circuit, the high voltage is 12000V.

[0084] In the embodiment of the present application, by Figure 4 The overall circuit of the plasma disinfection machine control circuit is shown in FIG. Figure 6 The overall circuit board diagram of the plasma disinfection machine control circuit is shown in the figure, and then the Figure 8 The circuit board of the plasma sterilizer control circuit is shown.

[0085] In the embodiment of the present application, the entire control circuit of the plasma sterilizer is coated with anti-radiation triple-proof paint, including the chip surface, chip pins, etc. The anti-radiation triple-proof paint has the functions of anti-radiation, insulation, moisture-proof, anti-leakage, shock-proof, dust-proof, anti-corrosion, anti-aging, and corona resistance, which can prevent it from being burned by the plasma returned to the plasma sterilizer.

[0086] In the embodiment of the present application, the control circuit of the plasma disinfection machine, the control circuit board module is connected to the boost power module, and the boost power module is connected to the electromagnetic coil module; the air disinfection and purification operation is performed through the control circuit board module, the boost power module performs boost control on the voltage of the control circuit board module, and the electromagnetic coil module ensures the stability of the boost control of the boost power module. The present application provides a new plasma disinfection machine different from the existing one, which controls each control function separately through the main control chip, so that even if some small functions are damaged, it will not affect the normal operation of the entire machine, and in the presence of high-voltage ions in the air, each control function is controlled separately, which can ensure that the circuit is not easily damaged and can perform disinfection and purification operations on the air.
