Description

Improvement of the air outlet structure of the air compressor cylinder

The present invention is an improvement of the air outlet structure of a cylinder of an air compressor, in particular to a cylinder provided with an air outlet tube seat, the outer tube wall of the air outlet tube seat is provided with a plurality of air outlet holes, and the outer tube wall is provided with an elastic Membrane, compressed air generated by the air compressor can enter the air storage chamber of the air storage seat by pushing the elastic membrane through the plurality of air outlets, and use the fast closing feature of the elastic membrane to allow compression per unit time into the air storage chamber of the air storage seat The air volume is greatly increased, so that the compressed air can quickly enter the air storage chamber through the air outlet, so that the operation of the piston body is smoother and the pumping efficiency is improved.

The air compressor used at this stage basically has a cylinder in its structure. The cylinder can provide a piston body to reciprocate to generate compressed air. The generated compressed air can be pushed by a valve mechanism through the air outlet of the cylinder to compress Air enters another space for storing compressed air. This space can be a space in an air storage seat (or an air collection tank). The air storage seat is also equipped with an air outlet to deliver compressed air to the air to be inflated. In order to complete the whole inflation purpose. Since there is only a single vent hole between the conventional cylinder and the air storage seat, the opening or closing of the vent hole is controlled by a valve mechanism, and the valve mechanism is composed of a valve seat and a spring. The piston body produces The compressed air pushes the valve seat and compresses the spring. The compressed air can enter the air storage chamber of the air storage seat. Since the compressed air collected in the air storage chamber will produce back pressure on the valve seat, the back pressure will be suppressed during the pumping phase The opening of the valve seat, in contrast, is that the compressed air generated during the operation of the piston body will have more resistance and not smooth when it moves the valve seat. This factor makes the piston body more resistant and slows down the inflation speed. , It is easy to cause the motor of the air compressor to overheat, the efficiency of the motor is reduced, and even the latent motor is burnt out. In view of the lack of the cylinder structure design of the conventional air compressor, the inventor developed it and developed the present invention after many efforts.
