A dustproof cylinder body of a car inflator pump

Abstract

This utility model discloses a cylinder body for a dustproof car air pump, including a right cylinder body assembly and a left cylinder body assembly. Both the right and left cylinder body assemblies include a first housing with a first mounting groove. An air inlet is formed within the first mounting groove, and an elastic filter is fixedly connected within the first mounting groove. The elastic filter has multiple filter holes evenly distributed on it. This utility model, by adding an elastic filter at the air inlet, utilizes the filter holes of the elastic filter to filter dust, sand, and other impurities in the air, effectively preventing impurities from entering the cylinder body. This avoids increased wear on moving parts such as pistons and valve plates due to friction, ensuring stable operation of the air pump and extending its service life. Simultaneously, the elastic filter is directly installed in the first mounting groove due to its own elasticity, requiring no additional fasteners, making disassembly and assembly convenient. Users can easily clean the accumulated impurities on the filter regularly to ensure smooth air intake. The overall design is simple in structure and low in cost, significantly improving the user experience and reliability of the product.

Description

Technical Field

[0001] This utility model relates to the field of air pump technology, and in particular to a cylinder body of a dustproof car air pump. Background Technology

[0002] A car air pump is a device specifically designed to inflate car tires and is widely used in in-vehicle emergency scenarios. The cylinder, as the carrier of the piston's reciprocating motion, must work in conjunction with the piston to complete the intake, compression, and exhaust of air, making it a key component connecting the intake, compression, and exhaust processes. To ensure smooth air entry into the cylinder, it is usually designed with an intake port. However, existing cylinder intake ports lack dustproof design, allowing dust to easily penetrate the cylinder interior, causing friction with moving parts such as the piston and valve plates, accelerating wear, and shortening the pump's lifespan. Some technologies design the intake port as a combination of multiple small holes, which can block some large particles by reducing the hole diameter, providing some dustproof effect. However, the small hole structure is easily clogged by dust, easily causing insufficient air intake, and even affecting the normal operation of the motor due to obstructed air intake.
