The utility model discloses in the access has three-way solenoid valve 16 between main trachea 28 and air pump 14, solenoid valve 16's three interface communicates with atmosphere, air pump 14 and main trachea 28 of taking out respectively.

Further, a liquid collector 15 is connected to a pipeline of the pumping and inflating system, which is communicated with the pumping and inflating pipe 12.

The liquid collector 15 mainly prevents the liquid in the material from being sucked to the air pump under the negative pressure condition, and the quality of the air pump is damaged. After partial liquid in the material is pumped into the pumping and inflating pipe and enters the liquid collector, the liquid is accumulated in the liquid collector and cannot flow to the air pump, so that the effect of gas-liquid separation is achieved, and the quality of the air pump is protected. When the piston head moves downwards, air is pumped, when the piston head moves back, the electromagnetic valve is opened, the atmosphere is communicated with the pumping and inflating pipe 12, the internal pressure and the external pressure are consistent, then the electromagnetic valve is closed, the air is refilled to push the piston head back, or the piston head is directly changed into an air cylinder to retract by itself.

The pumping and inflating pipe 12, the air pump 14 and the electromagnetic valve 16 form part of a pumping and inflating system, in order to further optimize the pumping and inflating system, one end of the air pump far away from the pumping and inflating pipe 12 is connected into a three-way pipe, three pipe orifices of the three-way pipe are respectively communicated with the air pump, a pure air source and a one-way valve, stop valves are respectively connected into the pipes communicated with the three-way pipe, the pure air source and the one-way valve, and meanwhile, the port of the electromagnetic valve 16, which is originally communicated with the atmosphere, is communicated with the pure air source through a pipe, as shown in fig. 8. When air needs to be pumped, the air pump discharges the air in the closed space through the one-way valve; when the internal pressure and the external pressure are required to be consistent, the pure air source supplies air to the closed space through the electromagnetic valve; when the piston needs to be pushed upwards, the air pump sends the air in the pure air source into the closed space.

The purified gas source can adopt nitrogen or air purified by a purifier.
