A small gear 701 is installed on the driving shaft of the motor 7, and the small gear 701 meshes with the transmission gear 6, and the transmission gear 6 meshes with the large gear 401; a three-way pipe 201 is provided on the top of the three-way sealing cover 2, and the bottom of the three-way pipe 201 is connected with the top of the pumping chamber 101, and the two ends of the top of the three-way pipe 201 are connected with two switching valves 8. The switching valve 8 is composed of a valve body 81, a valve core 82, a one-way valve 83, a top cover 84 and a valve shaft 85. The motor 7 drives the small gear 701 to rotate, and the small gear 701 drives the crankshaft 4 to rotate through the transmission gear 6. The crankshaft 4 drives the pumping piston 3 to reciprocate up and down through the transmission connecting rod 5. When the pumping piston 3 moves downward, the air enters the pumping chamber 101 through one of the switching valves 8. When the pumping piston 3 moves on the pumping piston 3, the air in the pumping chamber 101 is discharged through the other switching valve 8, which plays a role in detecting the breathing valve connected to the oil storage tank.

[0029] In the embodiment of the present disclosure, the valve core 82 is rotatably connected to the valve body 81, the one-way valve 83 is installed in the valve core 82, the two ends of the one-way valve 83 are connected to the two ends of the valve body 81, the bottom of the valve shaft 85 is rotatably connected to the valve body 81, the bottom end of the valve shaft 85 is inserted into the valve core 82, the top cover 84 is rotatably connected to the valve body 81, the valve shaft 85 runs through the top cover 84, and the valve shaft 85 is in the shape of an arrow pointing to the direction;

When the arrow pointing to the top of the valve shaft 85 is facing the pipeline connected to the oil storage tank, the pressurized air in the pumping chamber 101 enters the oil storage tank, and the inside of the oil storage tank is pressurized to achieve positive pressure detection of the breathing valve. When the arrow pointing to the top of the valve shaft 85 is facing the opposite state, the air in the oil storage tank is pumped into the pumping chamber 101, and the inside of the oil storage tank is depressurized to achieve negative pressure detection of the breathing valve.

When the pumping piston 3 moves downward, the air enters the pumping chamber 101 through one of the switching valves 8. When the pumping piston 3 moves upward, the air in the pumping chamber 101 is discharged through the other switching valve 8. According to the difference between the positive pressure and negative pressure detection required by the breathing valve, the valve core 82 is driven to rotate through the valve shaft 85 to change the direction of the two one-way valves 83. When the arrow pointing to the top of the valve shaft 85 is pointing toward the pipeline connected to the oil storage tank, the pressurized air inside the pumping chamber 101 enters the oil storage tank, pressurizing the inside of the oil storage tank to achieve positive pressure detection of the breathing valve; when the arrow pointing to the top of the valve shaft 85 is pointing to the opposite state, the air in the oil storage tank is pumped into the pumping chamber 101, decompressing the inside of the oil storage tank to achieve negative pressure detection of the breathing valve; during the negative and positive pressure detection process, the internal pressure value of the oil storage tank does not change much, indicating that the safe use of the breathing valve meets the standards.
