Abstract

An compressor contains a gap defined between a top of a piston and a valve so that when the air compressor stops, compressed airs are discharged out of the gap from a cylinder so that when the air compressor is turned on again, a upward movement is not stopped to avoid a raising of a compressed loading and electric currents, and the piston operates reciprocately in the cylinder, thus enhancing using safety and service life and inflating high-pressure airs to an object quickly.

Description

air compressor unit

The present invention relates to an air compressor device, in particular, a gap is formed between the top end surface of the piston head and the valve when the air compressor is stopped. When the air compressor is finished operating, the The compressed air remaining in the cylinder can be discharged from the gap, so that after the air compressor is restarted, the piston body will not have additional resistance during the upstroke, avoiding the instantaneous increase of compression load and current surge, resulting in the piston body in the cylinder. During the reciprocating motion, it can maintain a smooth compression performance, and is more safe to use and prolong its service life, and can more easily and quickly fill the object to be inflated with sufficient gas.

The inventor of the present invention has been devoted to the research and development of air compressor devices for a long time, not only transforming the early air compressors that were labor-intensive and complicated in structure into products with simplified structures and easy and rapid assembly, but also improved the structure of air compressors to strengthen the air Compressor performance. As shown in Figures 7 to 9, the main structure of the air compressor 9 is to drive a piston 92 by a motor to perform a reciprocating compression action in the cylinder 91, and the compressed air can be delivered from the cylinder 91 to the storage. In the air seat 96, a transmission hose connected to the manifold on the air storage seat 96 is connected to the object to be inflated. The conventional piston head 93 of the piston body 92 is provided with a vent hole 930 therethrough, and the piston A valve 95 is covered on the ventilation hole 930 of the head 93. When the air compressor 9 is stopped, the valve 95 closes the ventilation hole 930 of the piston head 93. , due to the airtightness formed by the airtight ring 94 provided on the outer periphery of the piston head 93 and the valve 95 closing the air passage 930 of the piston head 93, the high-pressure air remaining in the cylinder 91 cannot be discharged, and when the air compressor 9 When restarted, the piston body 92 hits the high-pressure air remaining in the cylinder 91 in the process of starting compression, which instantly increases the load of the air compressor 9 device and the current surges, resulting in the loss of the life of the air compressor 9 device. Therefore, the inventors have developed a gap between the top end surface of the piston head and the valve when the air compressor is stopped. Compressed air can be discharged from the gap, so that after the air compressor starts again, the piston body will not have additional resistance during the upstroke, avoiding the instantaneous increase of the compression load and the current surge, causing the piston body to reciprocate in the cylinder. It maintains smooth compression performance, is more safe to use and prolongs its service life, and can more easily and quickly fill the object to be inflated with sufficient gas.
