Description
Technical Field
The invention relates to the technical field of air compressors, in particular to an outer cover of an air compressor.
Background
An air compressor is a device that sucks in external air, compresses the air and outputs the air to form high-pressure air. The prior art air compressor usually sucks external air directly through an air inlet on the side wall of the casing and then pumps the air out, but the external environment may have impurity particles such as sand blown by the wind, and the prior art air compressor is particularly used in a dry outdoor environment. Therefore more among the prior art is that there is the shell at the air compressor machine dustcoat, the air inlet on the shell sets up the filter screen, thereby play dirt-proof effect, but this air compressor machine shell of current, if choose for use the filter screen that the filter effect is good then very easily lead to long-time use the back air inlet to diminish, thereby lead to the air input to reduce, the air intake volume of air compressor machine can't satisfy the output demand, if choose for use the filter screen that the filter effect is relatively poor although difficult for causing the jam, but the impurity of tiny granule is inhaled easily, long-term use probably leads to the damage of the inside unit of air compressor machine, especially impeller and the motor part of air compressor machine.
Therefore, how to realize dust prevention under the condition of meeting the air inflow requirement of the existing air compressor in the outdoor environment is a difficulty to be solved.
Disclosure of Invention
The present invention is directed to solving, at least to some extent, one of the technical problems in the related art: the air compressor outer cover is large in air inlet amount and good in filtering effect, and air inlets cannot be blocked along with use, so that the use requirement of outdoor environment is met.
To this end, an object of the present invention is to provide an air compressor casing, which includes a casing having at least one side wall formed by a ventilation board, or at least one side wall provided with a mounting opening for mounting the ventilation board, wherein: the ventilating plate comprises a base plate, a sealed containing cavity is arranged in the base plate, at least one cyclone unit is arranged in the containing cavity and comprises inner cylinders with openings at two ends, the inner cylinders are arranged along the vertical direction, the upper ends of the inner cylinders are communicated with air outlet holes in the inner surface of the base plate, the lower ends of the inner cylinders are communicated with air inlet holes in the outer surface of the base plate through the containing cavity, and openings at the lower ends of the inner cylinders are lower than the horizontal plane where the air inlet holes are located along the vertical direction. The centrifugal action that the air current through cyclone unit rotates and produce makes the foreign particle that contains in the gas get rid of to the inner wall in holding chamber by centrifugal force on, accomplishes the separation of air current and foreign particle, because this foreign particle's disconnect-type adopts cyclone unit to realize, need not the setting of filter screen, consequently can not lead to the problem that the air input that the filter screen mesh blockked up the result reduces along with the increase of live time.
