Abstract
A blowing device capable of preventing outflow of high-pressure air in a balloon during air change comprises a blowing horn (1), and is characterized in that an elastic air stopping plate (2) is arranged in an airflow passage of the blowing horn (1) and the liftable end of the elastic air stopping plate (2) is arranged in the direction close to a balloon (P). Accordingly, the blowing device has the advantages of convenience in use and low cost.
Description
Technical field
What the present invention relates to is that ventilation the time can stop the excessive blowning installation of balloon mesohigh gas, the blowning installation that promptly has " diode " function.
Background technique
At present, the blowning installation that people use, for example: in the process of blowing up a balloon, in ventilation, if pinch flat balloon port without hand, will make that the pressurized gas in the balloon are excessive from this balloon port especially, giving blows up a balloon causes trouble.
Summary of the invention
The present invention's purpose is to a kind of improvement of existing blowning installation, solves above-mentioned " trouble " problem.
In order to realize the purpose of foregoing invention, intend adopting following technology.
The present invention includes the air blowing horn body, it is characterized in that: in the air-flow path of above-mentioned air blowing horn body, be provided with the elasticity barge board, and the end that this elasticity barge board can perk is on the direction near balloon.
The present invention's characteristics compared with the prior art:
Easy to use, with low cost.---be particularly useful for the blowning installation that adopts when blowing up a balloon with " diode " function.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
1: the air blowing horn body; 2: the elasticity barge board; 3: gas hole; 4: the screw of location elasticity barge board; 5: groove; 6: air outlet hole; P: balloon.
Embodiment
(for example: length overall 30mm) air outlet hole 6 (for example: the balloon P of end aperture 12mm) to be arranged on air blowing horn body 1,3 air blowings allow balloon P inflate to gas hole by mouth, when mouth toward gas hole 3 (for example: when aperture 8mm) blowing, gas will back down elasticity barge board 2 by air outlet hole 6, and gas is arrived among the balloon P; When needs ventilation mouth is not blown toward gas hole 3, pressurized gas in air outlet hole 6 end balloon P are the application of force oppositely, force the elasticity barge board 2 that has been blown open oppositely to be closed, stop the pressurized gas among the balloon P excessive by air blowing horn body 1, what this moment, mouth just can be relieved is air-breathing, prepares to blow once more.---the present invention's plastics that can have drawn from.
During use, the pore of balloon P is enclosed within air outlet hole 6 ends in the air blowing horn body 1, and make the pore of balloon P cross the position of groove 5, because the pore of balloon P has elastic reaction, will make pore end and the groove 5 of balloon P form sealing state, afterwards, mouth just can be blown to balloon P by the present invention.
Claims (1)
1. can stop the excessive blowning installation of balloon mesohigh gas when taking a breath, it comprises air blowing horn body (1), it is characterized in that: in the air-flow path of above-mentioned air blowing horn body (1), be provided with elasticity barge board (2), and the end that this elasticity barge board (2) can perk is towards on the direction near the balloon (P) that is blown afloat.
