Description

Technical Field

[0001] The utility model relates to the field of air compressor equipment, in particular to an air compressor with a dustproof structure. Background Art

[0002] Air compressor is the abbreviation of air compressor. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. It is a gas pressure generating device for compressed air. A large amount of heat energy will be generated when the air compressor is running. When the temperature of the air compressor is too high, it will cause the air compressor to shut down and other abnormalities. To avoid this, a cooling fan is installed on the top of the air compressor to export the temperature inside the air compressor. When the cooling fan is running, a large amount of dust will enter the air compressor. When there is too much dust, it will also cause abnormal operation of the air compressor. To avoid this, the merchant installs a filter inside the air compressor to filter the air entering the cooling fan and reduce the amount of dust entering the air compressor.

[0003] The air compressor is specifically composed of a compressor, a cooling fan, a filter and a cooling hood. The cooling fan is arranged inside the compressor, and the filter is arranged on one side of the cooling fan. The filter filters the air drawn by the cooling fan to reduce dust in the air. The cooling hood is sleeved on one side of the outer surface of the compressor and is installed on the compressor through fixing bolts. After the air compressor has been used for a certain period of time, the staff is required to clean the filter regularly to ensure the filtering effect of the filter. When cleaning the filter, the staff is required to use tools to remove the fixing bolts of the cooling hood before cleaning the filter inside the compressor. The existing cooling hood disassembly process is relatively cumbersome, which reduces the maintenance efficiency of the staff to a certain extent.
