Novel plastic air pump machine core

Abstract

The invention provides a novel plastic air pump machine core. The novel plastic air pump machine core comprises a plastic air cylinder, a plastic piston, a plastic output disc and a power mechanism. The power mechanism comprises a plastic gear, a plastic rocker arm and a motor. The air pump machine core further comprises a plastic support fixing and supporting the motor, the plastic gear, the plastic rocker arm and the plastic air cylinder. The plastic output disc and the plastic air cylinder are fixedly connected through a rotation buckle. The plastic support is fixedly connected with the motor and the plastic air cylinder through rotation buckles. The whole novel plastic air pump machine core is arranged in the plastic shell, and the plastic shell is internally provided with clamping grooves matched with the plastic air cylinder, the plastic output disc, the plastic support, the plastic rocker arm, the gear and the motor. According to the novel plastic air pump machine core, reliable engineering plastic is adopted, a reasonable connecting mechanism is designed, the overall air pump machine core except the motor is made of plastic, the weight of the novel plastic air pump machine core is greatly reduced, installing is easier and more convenient, the production efficiency of enterprises is greatly improved, and the manufacturing cost of the enterprises is saved.

Description

technical field [0001] The invention relates to a novel plastic air pump core. Background technique [0002] The air pump core is a main functional part of the air pump, also known as the air pump and the inflator. It provides power through the rotation of the motor to drive the piston to compress the gas, and output compressed air to complete the function of inflating. The working process of the air pump core: when the motor is running, when pumping air, the valve of the connector is opened by the atmospheric pressure, and the gas enters the air cylinder, and when the air is pumped into the tire, the valve is closed by the air pressure in the air cylinder, and the gas enters the tire middle. [0003] At present, air pumps are widely used in fields such as automobiles, motorcycles, bicycles, rubber balls, and rubber boats. If the tire is punctured by nails or other hard objects in a relatively remote place, it is very necessary to use an air pump to temporarily replenish t...

AI Technical Summary

Problems solved by technology

At present, the air pumps on the market are all made of alloy materials to meet the requirements of each component, but this leads to a certain weight of the air pump, which brings inconvenience during use, and the price is too high. It is difficult to realize one car with one air pump, which is not conducive to Widely promoted, and the vehicle has a large load and high fuel consumption, which will cause a certain waste of resources
