Embodiment Construction

[0010] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0011] The 2 outer tubes and 1 switch of the present invention are made of hard plastic products, the 3 air guiding hose is a rubber hose, and the 4 spring is a metal spiral spring. The invention consists of an outer tube, a conduit, a switch and a spring. Its characteristic is that the opening and closing of the valve is controlled by the inflation state of the valve and the balloon. When the balloon is not inflated or filled with gas, the valve opens; when the balloon is full of gas, the valve closes, and the gas can neither be introduced nor exported.

[0012] The structure is as follows: the outer tube has a small opening radially, and the two ends of the tube are tightly connected with the two ends of the outer tube, so that the gas can only pass through the tu...

Abstract

The invention relates to a gas guiding hose sealing device. The gas guiding hose sealing device is characterized in that the gas guiding hose sealing device is composed of an outer tube, a guiding tube, a switch and a spring and has the functions that when a balloon is not inflated or not filled with gas, a gas valve is in an open state, and the gas is allowed to pass; and when the balloon is filled with the gas, the gas valve is in a closed state, the gas cannot be guided into and out, the gas valve automatically stops charging the balloon, and the balloon is prevented from exploded.

Description

Technical field [0001] The invention relates to a mechanical air valve, in particular to a sealing device for an air guiding hose. Background technique [0002] At present, the implementation process of the balloon sealing device is relatively complicated, and the sensitivity of some parts is relatively high, and the performance of the parts is unstable or accidents lead to a high failure rate of the device, and the cost is relatively high due to the requirements of accuracy. Summary of the invention [0003] The purpose of the present invention is to provide an air guiding hose sealing device, which has a simple structure and an intelligent inflation valve with low manufacturing cost. [0004] The technical scheme adopted by the present invention is: the present invention consists of an outer tube, a conduit, a switch and a spring. Its characteristic is that the opening and closing of the valve is controlled by the inflation state of the valve and the balloon. When the balloon is ...
