The specific working process is as follows:

1. startup horizontal calibration

After the power key 30 is pressed down and the power indicator 10 lights up the host component 200 and is powered on, the inclination angles of X, Y two shafts of the inclination angle sensor 600, namely the horizontal state, need to be automatically detected firstly, and the inclination angle data is sent to the single chip microcomputer, if the inclination angle data is not within the preset threshold range (plus or minus 3 degrees), the buzzer 700 continuously alarms at high frequency, the alarm lamp 20 flashes red to prompt that the plane of the inclination angle sensor 600 is not horizontal, and the 'horizontal automatic adjustment' is started by pressing an external confirmation key. If the air flow is within the preset threshold range, the vibration and swing exhaust is started.

2. Automatic level adjustment

After the confirmation key 40 is pressed, the 2 brushless motors are accurately controlled by a program to realize forward transmission and reverse rotation, so that the inclination angles of the X, Y two axes of the inclination angle sensor 600 are adjusted to be within a preset threshold range (+/-3 degrees), and the inclination angles of the X, Y two axes can be adjusted simultaneously. Wherein the threshold range and the brushless motor rotating speed can be quickly and manually adjusted through external hardware (a potentiometer). When the brushless motor rotates, the inclination angle sensor 600 continuously sends inclination angle data to the single chip microcomputer, the single chip microcomputer continuously calculates the inclination angles of the two shafts until the inclination angles of X, Y of the inclination angle sensor 600 enter a threshold range, at the moment, the brushless motor stops rotating, the buzzer 700 rings and stops, and the LED is changed from red light flickering to green light constant.

3. Vibrating, oscillating exhaust

After the horizontal automatic adjustment, the small vibration module 310 (a micro direct current motor with an eccentric wheel) is controlled by the single chip microcomputer to vibrate discontinuously, the brushless motor is started to rotate in a forward rotation and a reverse rotation alternately, the inclination angle of two shafts X, Y can be adjusted only by one shaft at the same time, namely, when the brushless motor rotates in the forward rotation and the reverse rotation, the brushless motor stops rotating, and when the brushless motor rotates in the forward rotation and the reverse rotation, the brushless motor rotates. The material object is shown in figure 1, and each time the vibration and swing exhaust are executed, a complete cycle is required. The brushless motor is mechanically combined with the tilt sensor 600, so that the tilt angles of the X, Y two axes of the tilt sensor 600 can be adjusted to be within a preset threshold range (± 30 °) through the number of turns of the brushless motor and are alternately changed. The positive and negative rotation time and the rotating speed of each brushless motor can be quickly and manually adjusted through external hardware (a potentiometer). The buzzer 700 takes three sounds as a group, the sounds are intermittently sounded, the LED indicator light turns red, the LED indicator light flickers at the same frequency as the buzzer 700, and the process lasts for 30 seconds. After 30 seconds, the brushless motor stops rotating, the buzzer 700 stops sounding, and the LED indicator light turns green and constant. Then, the "automatic horizontal adjustment" program is directly entered without pressing the enter key 40. It is noted that the "automatic horizontal adjustment" procedure is performed each time the "vibration, swing exhaust" procedure is performed.

4. Level condition monitoring

In a starting state, after the horizontal automatic adjustment is carried out for the first time, the single chip microcomputer monitors the inclination angle of the inclination angle sensor 600 in real time, and if the inclination angles of the inclination angle sensor 600 and the Y axis exceed the threshold range, the single chip microcomputer directly enters the horizontal automatic adjustment program without pressing the confirmation key 40.

5. Bubble monitoring

In a starting state, after the first vibration and swing exhaust, the single chip microcomputer monitors data returned by the bubble sensor 500 in real time, judges whether bubbles exist or not (the monitoring sensitivity can be quickly adjusted through a hardware circuit), and directly enters a vibration and swing exhaust program without a confirmation piece if the bubbles exist.

6. Lithium battery power supply

The circuit board has lithium battery charging circuit, and the accessible lithium cell is the power supply of complete set of device, is provided with charge indicator and low battery indicator, and accessible buzzer 700 was reported to the police when the electric quantity was low.
