Abstract
The invention discloses a vacuum air pump which comprises a shell. A vacuum pump and an air pumping device are respectively disposed in the shell. The air pumping device and the vacuum pump are integrally connected with the shell. A support rack is connected to the front end of the vacuum pump. Vacuum pipes are arranged on the support rack and penetrate the support rack to be connected with the vacuum pump in a sealed manner. A one-way valve is disposed on the lateral side of the vacuum pump and used for controlling operation of the vacuum pipes and the vacuum pump. The top of the air pumping device is provided with an exhaust pipe. The air inlet of the exhaust pipe is connected with the air outlet of the air pumping device. One end of the exhaust pipe is connected with the air pumping device, and the other end thereof is connected with a air filter device. The air filter device is connected with the exhaust pipe in a sealed manner through a seal plug. The vacuum air pump is convenient to operate, firm in polymerization molding, stable in connecting performance and convenient to assemble, air can be prevented from entering the shell from a silencer effectively, vacuumizing effect of the vacuum pump is guaranteed, and no other pipelines need to be externally connected to a container.
