Technical Field

[0001] The utility model relates to the technical field of energy-saving vacuum pumps, in particular to an energy-saving vacuum pump which is convenient for filtering. Background Art

[0002] Energy-saving vacuum pumps use a pair of gears that mesh with each other to achieve relatively synchronous operation. The driving shaft is connected to the output end of the motor through a coupling. When driving, the gears mesh with each other to form a negative pressure, thereby generating suction to evacuate the container to obtain a vacuum device or equipment.

[0003] When using an energy-saving vacuum pump for vacuuming, it is inevitable that some impurities will be mixed in it, and these impurities may damage the internal structure of the energy-saving vacuum pump; currently, a filter is installed at the air outlet of the energy-saving vacuum pump to prevent impurities from entering the energy-saving vacuum pump, but over time, too much impurity accumulates and the filter is easily clogged by impurities, and traditional filters are difficult to clean or replace.
