Full-stroke reciprocating piston type manual-operated compressor

Abstract

A full-stroke reciprocating piston type manual-operated compressor solves the problem that an existing mechanism is short in acting stroke, and is composed of a sealed shell, a piston, a long guide rod, a one-way valve and a sealing ring. When the full-stroke reciprocating piston type manual-operated compressor is used, supposing that the starting position of the piston is located at the bottom of the sealed shell, when the piston is pulled upwards, air pressure of a space below the piston is reduce, air inlet valves are opened, air enters the space, the air pressure of the space above the piston is raised, air exhaust valves are opened, and the air is exhausted. The return stroke operates in a reverse mode. When other containers need to be inflated, air outlets of two air outlet valves are connected with the container, and the container is inflated continuously in the full-stroke movement of the piston, and when air in the container needs to be exhausted, two air inlet valves are connected with the container, and air in the container can be exhausted continuously in the full-stroke movement of the piston. According to the full-stroke reciprocating piston type manual-operated compressor, the acting stroke of useful work of a machine is increased, so that the compressor or an extractor can inflate or deflate in the reciprocating process in a full stroke mode, the machine evenly acts, and the structure is simple and reliable.

Description

technical field [0001] The invention belongs to a fluid extracting or compressing device, in particular to a full stroke reciprocating piston manual compressor. Background technique [0002] At present, manual air compressors and manual air / water pumps are commonly used. Most of these compression or extraction devices use piston reciprocating motion to extract or compress fluids, such as air pumps, air extractors, etc., which require the user to go back and forth during use. Pull the piston to press out or draw in the fluid through the reciprocating motion of the piston, but this device can only extract in one stroke and compress in the return stroke, or compress in the forward stroke and extract in the return stroke, and cannot do work in the whole stroke, because of this Most of these devices do not work much at one time, and the cause of user fatigue is mostly due to the fatigue caused by too many times of exercise. Therefore, it is necessary to improve this type of devic...
