[0002] In daily life, mites and other microorganisms often attach to areas such as clothes, bedding and shoe uppers. Driven by people's pursuit of a better and higher-quality life, the demand for the function and portability of mite removers is growing. Traditional mite removers have defects such as single function, large size, and unfriendly human-computer interaction interface, which can no longer meet the current needs of people. At present, mite removers mainly generate a certain concentration of ozone through an ozone generator, and then use a fan to blow the generated ozone to the surface of clothing or quilts to kill attached mites and eliminate odors. In addition to killing mites, ozone also has the function of disinfection and sterilization. The multifunctional portable disinfection and sterilization mite remover uses different diffusion methods such as fans and air pumps to form ozone of different concentrations, and plasma achieves different sterilization, disinfection, mite removal, beauty (low temperature) and acne removal functions. Using a plasma generator and a fan, the air in the confined space is passed through the plasma generator to form positive and negative ions to neutralize the positive and negative charges in the air, which can effectively reduce the odor in the air and kill the viruses and bacteria in the air, and remove acne and mites for beauty (low temperature). With the development of electronic technology, ozone generators, plasma generators, fans and air pumps have all become miniaturized components, supporting the integration of multiple disinfection, sterilization, mite removal, beauty (low temperature) and acne removal functions into portable mite removers. With the enrichment of functions, a more friendly human-computer interaction interface is needed to meet the needs of use. At the same time, it is necessary to have a small size and strong control ability to achieve automatic control of various functions and portable human-computer interaction. In the face of the needs of miniaturization and multi-functional combination, the multi-functional portable disinfection, sterilization and mite removal device also needs to support the free switching of battery power and external power supply at the same time, and use low-cost, small-volume solutions to meet the different power requirements of different electronic components.

[0016] See also Figure 3 The 12V direct current input by the power plug (P9) is transmitted to the power interface (P7). In the power interface circuit, a diode VD1 is used to ensure that the control current flows in a single direction, thereby preventing reverse current from destroying the circuit in the controller.

[0017] See also Figure 3 The 12V DC input in the power interface circuit is connected to the positive pole of the built-in battery, and is connected to the keypad connector (P10) and the power button (SW2) through the power interface (P7). The power button (SW2) is a hold switch button. When pressed, the switch remains on. When pressed again and released, the switch is disconnected. That is, when the power button (SW2) is pressed, the 12V DC transmission circuit is open.

The HT1621B driver chip (M1) combines and regulates the high and low levels of the SEG0~SEG20 and COM0~COM3 pins in the form of high-frequency scanning according to the received signals, and then controls the level of the LCD display pins through the LCD display connector 1 (P4) and the LCD display connector 2 (P5), thereby controlling the display content of the LCD display.

[0021] See also Figure 2 , Figure 3 When the power button (SW2) is turned on, the STC8C2K08S microcontroller (U1) is powered on by an external power supply or a built-in battery. The STC8C2K08S microcontroller (U1) initializes and pulls up all control pins, and then detects whether the external power is connected through pin P1.5. When pin P1.5 is pulled down to a low level, it means that the external power is not connected. At this time, the STC8C2K08S microcontroller (U1) controls the power indicator light of the LCD display screen through the HT1621B driver chip (M1) to not light up. If pin P1.5 remains in a high level state, it means that the external power is connected. At this time, the STC8C2K08S microcontroller (U1) controls the power indicator light of the LCD display screen through the HT1621B driver chip (M1) to remain on.

[0022] See also Figure 2 , Figure 3 After the power button (SW2) is pressed, long press the function button (SW1) to connect the STC8C2K08S microcontroller (U1) pin P3.2 and the ground of the controller. As the function button (SW1) is released, the pin P3.2 and the ground of the controller will be disconnected. The STC8C2K08S microcontroller (U1) detects that the level of the pin P3.2 is pulled down for 2 seconds and then returns to a high level, indicating that the multi-functional portable disinfection and mite removal device is started. The STC8C2K08S microcontroller (U1) controls the LCD display to display the power on and the bedding mite removal and sterilization, wardrobe clothing disinfection and mildew prevention, indoor air purification and deodorization, 50m 2 The fonts of the six working modes are always on: virus disinfection and sterilization, powerful removal of residual medicines in fruits and vegetables, and sterilization and deodorization of kitchen and bathroom shoe cabinets.

[0023] See also Figure 2 , Figure 3After starting the multifunctional portable disinfection and mite removal device, short press the function button (SW1) to briefly pull down the level of the STC8C2K08S microcontroller (U1) pin P3.2, and restore the high level within 2 seconds. At this time, the working mode of the mite removal device is selected, including bedding mite removal and sterilization, wardrobe clothing disinfection and mildew prevention, indoor air purification and deodorization, 50m 2 The identification lights in front of the fonts of the six working modes, namely, virus disinfection and sterilization, powerful removal of residual medicines on fruits and vegetables, and sterilization and deodorization of kitchen and bathroom shoe cabinets, flash in turn. Each time the function button (SW1) is short pressed, the identification light of the next function flashes. When it reaches the last function, it automatically jumps back to the first function position. At the same time, the STC8C2K08S microcontroller (U1) counts for 2 seconds. If the function button (SW1) is not short pressed within 2 seconds, it means that the current function is selected for execution.

[0024] See also Figure 2 , Figure 3 After selecting the execution function, the STC8C2K08S microcontroller (U1) drives the corresponding load combination through the load drive module. The bedding mite killing and sterilization function is that the ozone generator (OZONE) and the fan (CLOUD) work together for 20 minutes, standby for 5 minutes, and cycle 8 times. The wardrobe clothing disinfection and mildew prevention function is that the ozone generator (OZONE) and the fan (CLOUD) work together for 20 minutes, standby for 2 minutes, and cycle 8 times. The indoor air purification and deodorization function is that the plasma generator (PLASMA) and the fan (CLOUD) work together for 30 minutes, standby for 5 minutes, and cycle 4 times. 50m 2 The virus disinfection and sterilization function is that the plasma generator (PLASMA) and the fan (CLOUD) work together for 30 minutes, standby for 5 minutes, and cycle 10 times. The vegetable and fruit residual medicine powerful removal function is that the ozone generator (OZONE) and the air pump (MOTOR) work together for 15 minutes, standby for 2 minutes, and cycle 3 times. The kitchen and bathroom shoe cabinet sterilization and deodorization function is that the ozone generator (OZONE) and the air pump (MOTOR) work together for 15 minutes, standby for 2 minutes, and cycle 6 times. The STC8C2K08S microcontroller (U1) controls the LCD display to display the countdown of the function execution time through the HT1621B driver chip (M1), so as to realize the display of the current working status of the multi-functional portable disinfection, sterilization and mite removal device.

[0025] See also Figure 2 , Figure 3After the specified function is executed, the STC8C2K08S microcontroller (U1) detects whether the function button (SW1) is pressed for more than 2 seconds through pin P3.2. If it is not pressed for a long time, it returns to the execution function selection position. If it is pressed for more than 2 seconds, it means that the multi-functional portable disinfection and mite removal device is turned off. The STC8C2K08S microcontroller (U1) controls the LCD display to turn off through the HT1621B driver chip (M1), except that the power indicator light is always on depending on whether it is currently using an external power supply or a built-in battery.
