An explosion-proof inflation nozzle for aluminum foil balloons

Abstract

This invention discloses an explosion-proof inflation nozzle for aluminum foil balloons, belonging to the field of balloon inflation nozzle technology. It includes an inflation seat body with an adhesive membrane attached to the outside of the body for connection to the aluminum foil balloon. An inflation channel is formed inside the inflation seat body, with a docking seat and an inflation seat on the inner wall of the channel. A docking nozzle is connected to the inner wall of a sealing ring, and a limiting ring seat adapted to the sealing ring is provided on the inner wall of the inflation channel. A sealing ball core is connected to the inner wall of the sealed air passage via a sealing elastic element. This invention senses the air pressure inside the aluminum foil balloon through a sealed pressure regulating space between the pressure-bearing membrane layer and the inner membrane body on the inflation seat body. The air pressure acts directly on the pressure-bearing membrane layer, causing the connected venting ring to move upward within the venting annular opening, opening the venting channel and releasing excess gas pressure to prevent the aluminum foil balloon from exploding during continuous inflation.

[0041] The further advantage is that: in the case of normal use, the aluminum film balloon will also be under certain pressure, but the pressure can be removed in time without explosion, and the pressure in the case of normal use will not be removed from the deflation channel 16, because the sealing ring 5 is located at the outlet of the deflation channel 16 without inflation, and the outer wall of the sealing ring 27 is arranged to block the deflation channel 16, so that the movement of the deflation ring 12 will not cause deflation, thereby ensuring that the deflation channel 16 is only opened when inflating, that is, ensuring the normal use of the aluminum film balloon, and avoiding the explosion of the aluminum film balloon during inflation.

[0044] When the pressure gradually increases during inflation and gradually reaches the limit of the aluminum film balloon, the air pressure in the aluminum film balloon will continue to increase, and the increase of the internal air pressure will cause the pressure to act on the pressure receiving film layer 36, which will cause the pressure receiving film layer 36 to be squeezed to move the trigger seat 11 connected thereto, and at the same time, the deflation ring 12 connected to the trigger seat 11 will move upward in the deflation ring-shaped port 15, when the pressure in the aluminum film balloon reaches the limit pressure, the conical tube 29 arranged on the deflation ring 12 will be inserted into the pressure relief seat 30, and the pressure relief ball 33 originally sealed will be moved, so that the gas in the aluminum film balloon is discharged from the deflation channel 16 to the outside, thereby realizing the discharge of excess gas pressure to the outside, so as to avoid the explosion of the aluminum film balloon during continuous inflation.
