working principle

In the present invention, the STC8A8K64S4A12 single-chip microcomputer 8 reads and processes the data of the air quality sensor module 20 to judge the pollution situation, and the MEGA 2560 9 controls the movement and the start-up of the purification module. The WIFI module 22 is connected, and the detected data is sent to the STC8A8K64S4A12 single-chip microcomputer 8 and the WIFI module 22 through the serial port, and the STC8A8K64S4A12 single-chip microcomputer 8 sends the data to the TFT full-color touch screen 21; the WIFI module 22 sends the data to the M _y SQL database so that Displayed on the web page.

P6.0, P6.1, P6.2, P6.3, and P6.4 of STC8A8K64S4A12 MCU 8 are respectively connected to digital pins 2, 3, 4, 5, and 6 of MEGA 2560. Among them, pin 2 of MEGA 2560 9 is the external interrupt 0 pin, which is set as falling edge interrupt. The eight states 0000-0111 of the four pins P6.1, P6.2, P6.3, and P6.4 of the STC8A8K64S4A12 single-chip microcomputer 8 respectively indicate that the moving direction is the front, the back, the left, the right, and the left There are eight directions: front, left rear, right front, and right rear. The ninth state 1000 indicates that pollutants have diffused and mobile coverage purification should be performed; STC8A8K64S4A12 single-chip microcomputer 8 reads and processes the data of air quality sensor module 20. The concentration value of pollutants judges the pollution situation and sets P6.1, P6.2, P6.3, and P6.4 to corresponding values, then first sets P6.0 to 1, and then sets P6.0 to 0, resulting in a decrease along. When the values of P6.1, P6.2, P6.3, and P6.4 are 1000, start timer 0, reset P6.0 to 1 after 1 minute, and turn off timer 0; when it is 0000-0111, start Timer 1, reset P6.0 to 1 after 5s, and turn off Timer 1. When P6.0 is set to 0, MEGA 2560 9 starts the purification module and starts the timer at the same time, and turns off the purification module after 1 minute. Mobile covering purification; when it is 0000-0111, the purifier controls the silent planetary gear motor 2 to move a certain distance in the specified direction.

When the main body is moving, the silent planetary gear motor 2 works, and the bottom plate 1 drives the device to move by controlling the omnidirectional wheel 3, through three flexible film pressure-sensitive sensors 10 around the entire purifier shell and ultrasonic modules 11 in three directions to avoid obstacles. When the distance read by a certain ultrasonic module 11 is less than the set value, the purifier retreats and rotates at a certain angle before moving forward; when the purifier collides in a certain direction, the flexible film pressure-sensitive sensor 10 in the corresponding direction outputs a high level, The purifier retreats and rotates at a certain angle before moving forward.

When the purification module is working, the air is first sucked through the air hole 32 of the casing 12, and then passes through the air inlet 24 to contact the cylindrical composite filter element 18 for initial filtration, and then passes through the negative ion generating device and the plasma generating device 13 for deposition. The fan 15 blows the deposited air through the composite filter screen 16 for secondary filtration, and finally the clean air is blown into the room from the lower side of the base 1 through the second fan 17 . The positive ions and negative ions generated by the plasma generating device at the same time produce a huge energy release at the moment of neutralization of positive and negative charges in the air, resulting in changes in the structure of the surrounding bacteria or energy conversion, resulting in the death of the bacteria and realizing its bactericidal effect . Since the number of negative ions is greater than that of positive ions, the excess negative ions are still floating in the air, which can eliminate smoke, dust, eliminate odors, improve air quality, and promote human health. Plasma has: deodorization, smoke deodorization, leather deodorization, foot odor deodorization, perspiration deodorization, sterilization and disinfection. Negative ions have: fresh air, increased oxygen supply, car air intake, air-conditioned room, second-hand smoke, and PM2.5 removal.

When the air purification mode is selected, MEGA 2560 9 controls the silent planetary gear motor 2 and the control motor 5 to stop running, and the STC8A8K64S4A12 microcontroller 8 reads the data of the air quality sensor module in real time. When the read data exceeds the threshold, P6.1, Set P6.2, P6.3, and P6.4 to 1000, first set P6.0 to 0, then set P6.0 to 1, generate a falling edge, and start timer 0 at the same time, reset P6.0 after 1 minute 1. Turn off the timer. At this time, MEGA 2560 9 controls the purification work. At the same time, start the timer, and the purifier will purify on the spot for one minute. If the data detected by the sensor still exceeds the threshold after one minute, continue to purify.

When the sweeping-air purification mode is selected, the purifier detects the air quality while sweeping the floor. When the data of the air quality sensor module 20 read by the STC8A8K64S4A12 microcontroller 8 exceeds the threshold and the data in each direction differs very little, set P6.1, P6.2, P6.3, and P6.4 to 1000, and first set P6.0 Set it to 0, then set P6.0 to 1, generate a falling edge, and start timer 0 at the same time, reset P6.0 to 1 after 1 minute, and turn off timer 0. At this time, MEGA 2560 9 controls the cleaning work to start, and starts at the same time Timer, the purifier performs covering cleaning for one minute while sweeping the floor, if the data detected by the air quality sensor 20 still exceeds the threshold after one minute, then continue. When the data read by the air quality sensor 20 exceeds the threshold and there is a certain difference in different directions, set P6.1, P6.2, P6.3, and P6.4 to a value between 0000-0111 according to different situations , set P6.0 to 0, then set P6.0 to 1, generate a falling edge, start timer 1 at the same time, reset P6.0 to 1 after 5s, and turn off timer 1, at this time MEGA 2560 9 controls the purification work , start the timer at the same time, stop working after one minute, and the purifier starts to locate, track, and purify pollution. STC8A8K64S4A12 single-chip microcomputer 8 will send a movement signal to MEGA 2560 9 every five seconds according to the value read by the air quality sensor to control the movement of the purifier. Until it judges and finds the source of pollution or the concentration of pollutants drops.
