Description

Air Compressor The present invention relates to an air compressor, and more particularly to a piston-type air compressor. Vehicle-mounted air compressors can be used in conjunction with tire sealant bottles to repair and inflate vehicle tires, or they can be used to inflate vehicle tires without tire sealant bottles. The air compressor may be a piston-type air compressor in which a piston advances within a cylinder to compress the air inside the cylinder, causing high-pressure air to flow out through the front of the cylinder. As the piston moves backward within the cylinder, the space inside the cylinder gradually increases, causing the air pressure inside the cylinder to decrease; when the next piston advances, the compression cycle continues. Piston-type air compressors heat up during operation, so a cooling fan is typically installed coaxially with the motor used to drive the piston. However, due to the compact internal structure and limited space of the air compressor, which results in poor cooling airflow efficiency, the above heat dissipation design does not effectively achieve sufficient heat dissipation. The accompanying drawings are provided to aid in a better understanding of the present invention and are included in and constitute part of this specification. The drawings illustrate exemplary embodiments of the present invention and serve to explain the principles of the present invention together with the detailed description.
