Low-pressure large-flow air pump

Abstract

The invention relates to a low-pressure large-flow air pump. The low-pressure large-flow air pump comprises an outer shell, an inner cylinder and a piston, the inner cylinder is of a hollow columnar structure, a left sealing cover is arranged on one side of the inner cylinder, a right sealing cover is arranged on the other side of the inner cylinder, the piston is arranged on the outer side of the inner cylinder in a sleeving mode and located between the left sealing cover and the right sealing cover, the outer shell is arranged on the outer side of the inner cylinder and the outer side of the piston in a sleeving mode, the outer surface of the piston and the outer surfaces of the left sealing cover and the right sealing cover are sealed, a transmission device for driving the piston to move back and forth between the left sealing cover and the right sealing cover is installed on one side of the interior of the inner cylinder, a hollowed-out air channel connected with the end faces of the two sides is formed inside the piston, one-way valves are installed at the two ends of the hollowed-out air channel correspondingly, and a ventilation connector device is installed on the other side of the interior of the inner cylinder. The air pump belongs to a reciprocating type positive displacement pump, continuous work is achieved through reciprocating double actions, air suction and compression can be achieved back and forth, and therefore large flow is provided.

Description

Technical field[0001]The present invention relates to the field of air pumps, and more particularly to a low voltage large flow air pump.Background technique[0002]In a large volume of inflatable pad, most of the inflatable airbag products, most of which is not suitable for frequent charge and discharge gas, because the amount of gas is large, the inflation process is slow, but provides sufficient flow of air pump, or large noise, or high power Resulting in high cost. In fact, these air cushions need to be very low, but the required flow is relatively high, the actual power is not large, so many occasions, people will use the manual air pump to solve, the decrease in inflation is reduced, and the air cushion is reduced. Use performance.Inventive content[0003]It is an object of the present invention to provide a low voltage large flow air pump to solve the problems encountered in the above background techniques.[0004]In order to achieve the above object, the technical solutions of the...

AI Technical Summary

Problems solved by technology

[0002] Most of the large-volume inflatable cushions and inflatable airbag products are not suitable for frequent inflation and deflation, because the inflation volume is large, the inflation process is slow, and the air pump that provides sufficient flow is either noisy or needs to provide high power instead. cause high cost

In fact, the pressure required for these air cushions is very low, but the required flow rate is relatively high, and the actual power required is not large. Therefore, in many occasions, people will use manual air pumps to solve the problem. The reduction in inflation speed greatly reduces the cost of air cushions and other products. performance
