Description

Technical Field

[0001] The utility model relates to the technical field of vacuum air pumps, in particular to a combined vacuum air pump. Background Art

[0002] In the machinery industry, it is often necessary to use a vacuum air pump to evacuate or provide high-pressure gas to gas-using equipment. The vacuum air pump generally compresses and stretches the air in the pump chamber through the reciprocating motion of a mechanical device to form a negative pressure, and draws air inside the equipment through the suction port to create a vacuum environment, or supplies air to the gas-using equipment through the blowing port. Traditional vacuum extraction or air supply equipment uses a single vacuum air pump to evacuate or supply air. When the vacuum suction force is large, the blowing pressure value becomes smaller accordingly. Conversely, the vacuum pressure value will also become smaller when blowing. The vacuum pressure and the air supply pressure restrict each other, so that a single vacuum air pump cannot meet the requirements of continuous vacuum pressure and blowing pressure value at the same time. Multiple vacuum air pumps are used to evacuate and supply air to the equipment respectively, which is large and bulky, occupies a lot of space, and has cumbersome installation and connection.

[0003] As in the patent application with application number CN201921711066.6, a first vacuum pump is installed inside the mounting frame, and a second vacuum pump is installed above the mounting frame. The blowing port of the first vacuum pump extends upward through a ventilation pipe and is connected to the exhaust port of the second vacuum pump. The exhaust port of the first vacuum pump is the vacuum end, and the blowing port of the second vacuum pump is the air supply end. The air pump combination is formed by the first vacuum pump and the second vacuum pump, which can continuously provide power. When the air pressure of one vacuum pump is insufficient, the other vacuum pump provides compensating power. One of the vacuum pumps can be operated alone, or the two can be operated in combination at the same time, and the requirements of continuous vacuum pressure and blowing pressure values ​​can be met at the same time. The structure is compact, the size is small, and the installation and connection are convenient.

[0004] However, when the above-mentioned combined vacuum air pump is used, the number of vacuum air pumps that can be installed on the mounting frame is limited, which makes it impossible for the staff to install multiple vacuum air pumps for use according to the actual situation, thereby reducing the use effect of the combined vacuum air pump. It is urgent to design a combined vacuum air pump to solve the above problem. Utility Model Content
