Abstract

The present application relates to a miniature vacuum machine with a filtering structure, and relates to the field of vacuum machines, including a casing, a vacuum pump installed in the casing, and a filtering device arranged in the casing, and the filtering device includes a first A filter device and a second filter device, one end of the first filter device protrudes from the housing to be connected to a vacuum bag, the other end of the first filter device is connected to one end of the second filter device, and the second filter device One end of the filter device away from the first filter device communicates with the air inlet of the vacuum pump, the first filter device includes a first filter tube and a filter screen fixed inside the first filter tube, the second The filter device includes a second filter tube and filter cotton detachably connected in the second filter tube. The application has the effect of reducing the dust contained in the air accumulating in the pump cavity of the vacuum pump and causing damage to the vacuum pump.

Description

technical field [0001] The application relates to the field of vacuum machines, in particular to a miniature vacuum machine with a filtering structure. Background technique [0002] The vacuum machine can take the air out of the vacuum bag, so as to keep the products placed in the vacuum bag fresh. At present, the vacuum machine is widely used in the electronics industry, the refrigeration system of the electroplating industry, the food industry, and the medical industry. [0003] A vacuum pump is installed in the vacuum machine, and the air in the vacuum bag can be sucked away by the vacuum pump. However, since the air currently contains a lot of dust and impurities, when the vacuum machine works for a period of time, the dust contained in the gas pumped by the vacuum pump located in the vacuum machine will accumulate in the pump chamber of the vacuum pump, destroying the flow rate of the vacuum pump and The degree of vacuum will affect the normal vacuuming operation.
