Specific embodiment
This utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of gas mixing ratio case includes oval casing 1, the gas of one end open in oval casing 1, is provided with
Bag 2, at least two air inlet pipe 3（The quantity of air inlet pipe 3 is related to the mixed gas composition species for needing proportioning, for example, have two kinds
Gas mixing, i.e., using two air inlet pipe 3, if any three kinds of gas mixings, i.e., using three air inlet pipe 3, each gas adopts one
3 air inlet of root air inlet pipe）Connect with airbag 2, the opening of airbag 2 is connected with the gas outlet 4 being located on oval casing 1；
As in Fig. 2, gas outlet 4 includes arcuate groove 41, is provided with outlet in 41 bottommost of the arcuate groove, and outlet is provided with out
Air valve, is provided with backing plate 42 in arc inside arcuate groove 41,2 open circumferential mould of airbag backing plate 42 in the arcuate groove 41 with arc
Between, 2 open circumferential film inner surface of airbag is additionally provided with reinforcement silk screen 5, and in arc, backing plate 42 contacts with silk screen 5 is strengthened, airbag 2
Open circumferential film outer surface is contacted with arcuate groove 41, in such as Fig. 3, is strengthened silk screen 5 and is provided with irregular projection block 6, projection
Block 6 is to raised away from 2 open circumferential film inwall direction of airbag；
Cushion pad 7 on reinforcement 5 projection block 6 of silk screen is covered, wear 3 and cross backing plate 42 and gas in arcuate groove 41, arc by air inlet pipe
Connect inside bag 2；
1 inwall of oval casing is provided with multiple pressure inductors 8, and operator are by observing diverse location pressure sensitive
The change of device 8, you can know the size of the expansion of airbag 2, in order to ensure the accuracy of proportioning, the shape after the expansion of general airbag 2
Similar to 1 interior shape size of oval casing, the volume of final mixing match is also identical with 1 internal volume of oval casing,
When airbag 2 is expanded into maximum, it is that mixed gas are volume required；At least one water inlet pipe 9 is additionally provided with oval casing 1,
1 one end of oval casing is provided with the arcuate groove 41, other end and is provided with electric magnet 10；Airbag 2 opening the other end be provided with metal gauze or
