Air bag provided with built-in hand pull pump

Abstract

The invention discloses an air bag provided with a built-in hand pull pump. The air bag is provided with an opening, the built-in hand pull pump is installed at the opening, the hand pull pump comprises a pump shell and a push-pull assembly, the edge of the pump shell is fixed to the opening of the air bag, and the bottom of the pump shell is located in the air bag; an air outlet is formed in the bottom of the pump shell and provided with a one-way valve; the push-pull assembly comprises a push-pull rod and a sealed air outlet structure, and one end of the push-pull rod is connected with the sealed air outlet structure; the push-pull rod is pushed to drive the sealed air outlet structure to slide along the inner wall surface of the pump shell, and external air is driven to enter the air bag through the sealed air outlet structure to inflate the air bag. Therefore, the external air is driven to enter the air bag through the sealed air outlet structure to inflate the air bag, and the air bag is ingenious in structural design, quite convenient to use and easy to achieve.

Description

technical field [0001] The invention relates to the technical field of inflatable products, in particular to an air bag with a built-in hand pump. Background technique [0002] The air pump is a key component of various inflatable products (such as air mattresses, inflatable trampoline, inflatable sofas and large inflatable toys). It is installed on the inner side of the soft bladder of the inflatable products. The product performs operations such as rapid inflation, pressure maintenance and rapid deflation, so as to realize the functions of inflatable products for normal use and deflation to reduce the space volume for storage. [0003] The current air pumps are mainly divided into electric air pumps and manual air pumps. The existing manual air pumps are similar in principle to inflators, but the external gas is charged into the interior of the product to be inflated by pushing and pulling. The built-in hand pump is to install the manual pump on the air bag. The performan...

Problems solved by technology

[0003] The current air pumps are mainly divided into electric air pumps and manual air pumps. The existing manual air pumps are similar in principle to inflators, but the external gas is charged into the interior of the product to be inflated by pushing and pulling. The built-in hand pump is to install the manual pump on the air bag. The performance of the existing built-in manual pump is somewhat unsatisfactory, the inflation efficiency is low, the sealing is also poor, and it is easy to leak after inflation, etc. The overall performance is not ideal
