Description

Improvement of the air outlet structure of the air compressor

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 outlet tube seat, the tube wall of the outlet tube seat is provided with multiple notches, and an elastic cover is sheathed on the tube wall of the outlet tube seat , The compressed air generated by the air compressor can enter the air storage chamber of the air storage seat by pushing the side wings of the elastic cover through these multiple notches. The quick closing feature of the side wings of the elastic cover allows the air to enter the air storage seat per unit time. The compressed air volume of the air storage chamber is greatly increased, so that the compressed air can quickly enter the air storage chamber through the gap, which makes the operation of the piston body smoother and improves the pumping efficiency.

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 the cylinder's air outlet to a valve mechanism 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, reduce the efficiency of the motor, and even cause the loss of the latent motor to burn. 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.
