[0012] Beneficial effects of the utility model:

[0013] 1. According to the previous experience, the screw vacuum pump has been used for too long, and the screw surface and gap will wear, resulting in gaps between its structures and leakage. It is not easy to check, which affects the working efficiency of the pump. The difference is that the pressure intake detection component can be used to drive the single-head spiral screw to turn when the pump body starts working, and the airtight environment state startup quantity can be timely detected. As the gas gradually flows, the single-head spiral screw turns, causing the internal airflow to change. The airflow will flow circumferentially along the pump tube, and simultaneously press on the extrusion airbag ball. The circumferential airflow detection component is used to detect the air pressure flow in an annular direction to improve the overall detection effect. As the filling pipe is filled, the concentration sensor senses the appropriate range, indicating that the internal quantity is full, and the feedback is on the first flashing light, so that it can be observed in time to ensure the overall operation stability.

[0014] 2. When the airflow impacts in a circular direction, the vibration of the pump body is transmitted to the spring column, which provides shock absorption protection, strengthens the structural connection, and improves the structural sealing effect. As the pressure sensor inside the airbag is squeezed, the pressure is sensed and fed back to the display screen, and then fed back to the background through the signal device.
