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.

Description

Vacuum air pump
Technical field
The present invention relates to a kind of air extractor, more particularly to a kind of vacuum air pump.
Background technology
The type of vavuum pump is varied, and it is widely used in the fields such as plastics machinery, pesticide chemical, dye chemical industry, Cryo Equipment, papermaking equipment and food machinery.The operation principle of vavuum pump is mainly by modes such as the volume changes or extruding of container, reaches the purpose of exhaust.During being vacuumized to container, the often requirement to vacuum in container has certain limitation, as long as vavuum pump just carries out vacuumizing action when i.e. vacuum is higher than setting, in order to detect the vacuum in container, conventional method is by connecting pipeline and reservoir at present, and pressure sensor is set on connecting pipeline, by the pressure in pressure sensor detection container, and then determine the vacuum in container.When the vacuum values in container are less than setting, pressure sensor is sent and feeds back signal to vavuum pump so that vavuum pump is started working, but existing vavuum pump is also unable to reach more preferable effect, also need to make it certain improvement, can just better meet the demand of enterprise.

To achieve these goals, the technical solution adopted by the present invention is such:It is of the invention including housing,Vavuum pump and air extractor are respectively equipped with housing,Air extractor and vavuum pump are integrated with housing and are connected,Vavuum pump front end is connected with bracket,Bracket is provided with vacuum tube,Vacuum tube is tightly connected through bracket with vavuum pump,Vavuum pump side is provided with check valve,Check valve is used to control vacuum tube and vacuum pump work,Air extractor top is provided with blast pipe,The air inlet of blast pipe is connected with the gas outlet of air extractor,Blast pipe one end is connected with air extractor,Its other end is connected with gas-filtering device,Gas-filtering device is tightly connected by a sealing-plug and blast pipe,Gas-filtering device is provided with exhaust outlet,Exhaust outlet extends outside housing through housing,Also include muffler and tracheae,The gas outlet of vavuum pump is connected by a connecting tube with muffler,Muffler and housing integrally connected,Muffler is provided with hush pipe,Hush pipe is connected through tracheae with housing,Tracheae two ends are flexibly connected with housing both sides inwall.
Further, as a kind of specific structure type, sealing-plug of the present invention includes a minor diameter part and a large-diameter portion, and minor diameter part is connected with gas-filtering device, and large-diameter portion is connected with blast pipe.
Further, as a kind of specific structure type, sealing-plug of the present invention is rubber seal plug.
Further, as a kind of specific structure type, the spacing between the exhaust outlet and muffler of vavuum pump of the present invention is two to three centimetres.
Compared with prior art, the advantage of the invention is that:Vacuum air pump of the present invention is easy to operate, and polymerization forming firmly, can effectively prevent gas from being entered into housing from muffler, and so as to ensure that the vacuumizing effect of vavuum pump, and without the external other pipelines on container, switching performance stabilization, assembling is more convenient.
