Problems solved by technology

In the foregoing description, the rubber ring with a circular or rectangular cross-section as shown in Figure 11 cannot fully respond to the change in the gap between the cylinder and the connecting rod and piston integrated. If the rubber ring is enlarged, it will cause Decrease in air filling capacity

[0083] Looking at the present invention, a rubber ring is provided between the piston and the inner wall of the cylinder. As mentioned above, because the rubber ring is V-shaped, it can solve the gap change between the piston and the cylinder caused by the inclination change of the integrated piston that cannot be solved by the O-ring. Problem, and because the gap is filled by the deformation of the outer rib of the rubber ring when the force is applied, the force on the piston is further reduced, and the durability of the product is improved by reducing friction. Again because of the expansion and contraction of the outer ribs of the above-mentioned rubber rings at low temperatures, the deform...

Abstract

A small and simple air filler for tyre is composed of a detachable casing, a motor, a small air compressor with V-shaped rubber ring between piston and inner surface of cylinder, and air delivering unit. Its advantages are high reliability and performance, small size and light weight.

Description

technical field [0001] The present invention relates to a small and simple air filling device which is reliable, high-performance and can be used to generate high-pressure air even at low temperature. Especially when a tire blows out, it can be used together with a sealant to carry out air filling for a blown tire. It is a combined small air filling device that can be repaired in an emergency. Background technique [0002] At present, there are air compressor products for tire emergency repair, but there is still a reliable small and simple air compressor on the market that can be mounted on a car, which is small, light, has good durability, and can be used for emergency repairs when a tire blows out. Requirements for emergency repair kits. [0003] The current small-sized air compressor is shown in Figure 11: it has a motor m, a reduction gear driven by the motor, a gear-embedded crank disc k, a connecting rod n connected to the crank disc k, and a piston q at the front en...
