Air compressor inlet and outlet clearance structure

The invention relates to an air inlet and outlet hole tight-fixing structure of an air compressor, mainly for a partition inlet and outlet hole and an inlet and outlet valve piece disposed between a cylinder and a gas chamber of an air compressor, when the piston member reciprocates It is designed to solve the problem of the deflation of the conventional structure, so as to improve the overall efficiency of the work.

According to the design of the small air compressor for non-industrial use, please refer to the figures 1 and 2, mainly equipped with a small air compressor motor (10), which is located at one end of the air compressor motor (10). a transmission shaft chamber (11), a piston member (12) is disposed inside the transmission shaft chamber (11), a sleeve (13) is sleeved on the upper portion of the piston member (12), and the upper portion and the shaft of the piston member (12) are arranged The sleeve (13) is disposed in a cylinder (14) to enable the piston member (12) to reciprocate in the cylinder (14) under the limit of the sleeve (13), and at the top of the cylinder (14) There is further provided a gas chamber (15), which is further divided into an inlet chamber and an outlet chamber, and a partition (16) is arranged between the cylinder (14) and the gas chamber (15). And a partition hole (16) is respectively provided with an air inlet hole and an air outlet hole at the air inlet chamber and the air outlet chamber, and a metal valve piece (17) is respectively locked on the lower side of the air inlet hole and the upper side of the air outlet hole to respectively respectively Covering the inlet and outlet holes, and holding a grip handle (18) having the function of the intake pipe on the side of the inlet chamber, and connecting the outlet assembly (19) on the side of the outlet chamber, thereby forming The basic functional architecture of such small air compressors; In the above structure, the piston member is reciprocated to generate the inflow and outflow operations, and the opening and closing operations of the metal valve piece covered by the inlet and outlet holes are relatively open and closed as the inlet and outlet operations are performed. However, when the air compressor is stopped, the state of the piston member cannot be ensured. If the intake valve plate is in close contact with the intake hole when the engine is stopped, when the air compressor is restarted, it may be Due to the action of the negative pressure suction, the piston member needs a large amount of power to operate, causing the starting action to be unsuccessful, and may even cause damage to the machine, which is generally in the design of the intake valve piece. It will slightly tilt its moving end at a predetermined angle, so that it can maintain a slight clearance with the air intake hole to prevent the generation of negative pressure suction, so that its starting operation is smoother, but in this structure When the piston member is lifted up, its top surface will inevitably hit the intake valve plate, which not only causes noise, but also may damage the structure of the intake valve plate, which will affect its use invisibly. Life, increased maintenance and replacement The number and cost, said Juenan ideal design, there is a need to try to be addressed to improve those.

In order to solve this problem, the inventor has made an improved design of the air intake valve plate of the air compressor (application number: 100110440), which is used to cover the bottom of the partition to cover the air inlet and its supply. The predetermined depth of the bolt hole portion of the inlet valve plate is offset, so that the bolt hole portion and the bottom surface edge of the partition plate have a difference of at least or greater than a thickness of the inlet valve plate, so that the intake valve plate is assembled. When the step is grooved, it can be hidden in the step groove without the protrusion of the bottom surface of the partition plate. As a result, when the piston member is lifted upward, there is no collision with the intake valve plate to generate noise or structure. Damaged.

However, the above-mentioned structure can solve the problem of collision noise and structural damage of the piston member, but due to the slightly tilting design of the movable end of the inlet and outlet valve pieces and the drop structure of the bolt hole portion, the piston member reciprocates in the reciprocating manner. During the process of moving in and out, the inlet and outlet valves may not be able to The inlet and outlet holes are completely close together, resulting in a phenomenon of deflation, which will affect the efficiency of the operation of the inlet and outlet, and the power of the overall pressure output, and it is necessary to solve the improvement.

In view of the conventional air compressor's structural design of the inlet and outlet valve plates, the inventors may face problems that cannot be separated from the inlet and outlet orifices during the process of reciprocating lifting and moving of the piston member. Specially researched and improved, based on its years of experience and technology in related industries, the R&D and venting structure of the present invention was developed.

In order to obtain the sealing effect of the inlet and outlet valve sheets and the inlet and outlet holes, the present invention is mainly designed to provide a groove in the periphery of the inlet and outlet holes to respectively fix and fix a dense ring, and The height of the tight ring is between the surface of the baffle and the hole of the bolt. Therefore, the effect of maintaining a slight clearance between the movable end of the inlet and outlet valves and the inlet and outlet ports respectively is not affected when the air compressor is stopped. In addition, when the piston member is reciprocated after the air compressor is started, the inlet and outlet valve sheets can be surely obtained the sealing effect to prevent the possibility of deflation, thereby greatly improving the overall working efficiency.

The design of the inlet and outlet holes for the air compressor developed by the air compressor is designed to embed the sealing ring through the periphery of the inlet and outlet holes without affecting the anti-negative suction performance of the air compressor. In the process of ensuring that the piston member is reciprocatingly moving up and down, the inlet and outlet valve pieces have a stop-tightening effect with their inlet and outlet holes in a timely manner, so that the air pressure output is not deflated, thereby making the air pressure output more reliable, and can be greatly Improve the overall efficiency of the work.
