Abstract
A kind of gas-detecting device, comprise apparatus main body, display screen, aerating and exhaust device, display screen is arranged on the surface of apparatus main body, aerating and exhaust device is arranged on the below of apparatus main body, described aerating and exhaust device comprises spring, steel ball, air flue, O-ring seal, gas filling valve, and air flue comprises transverse air channel and vertical air flue, and transverse air channel and vertical air flue are interconnected and form cross air flue, one end communication apparatus main body of vertical air flue, other end sealing; Spring and steel ball are arranged in transverse air channel, and one end of spring is fixed on the sidewall of transverse air channel, and the other end is connected with steel ball; The outer end of transverse air channel is connected with gas filling valve, and in junction, O-ring seal is set and seals.Gas-detecting device provided by the utility model, the in the situation that of change structure not, can freely be inflated and exit, and gas is changed, thereby effectively guaranteed the measuring accuracy of detector.
Description
Technical field
The utility model relates to a kind of electronic product, especially a kind of gas-detecting device.
Background technology
Gas-detecting device can judge equipment under test is in which kind of duty by concentration or the color of gas, common gas-detecting device can not at will carry out inflation/deflation, the words that service time is of a specified duration, gas may be revealed, the chemical property of gas also may change, and these all can affect the precision of detection greatly; If replacing gas, will change the structure of gas-detecting device, cost is higher.
Utility model content
For addressing the above problem, the utility model provides a kind of new gas detecting device, and its technical scheme adopting is as follows:
A kind of gas-detecting device, comprise apparatus main body, display screen, aerating and exhaust device, display screen is arranged on the surface of apparatus main body, aerating and exhaust device is arranged on the below of apparatus main body, described aerating and exhaust device comprises spring, steel ball, air flue, O-ring seal, gas filling valve, and air flue comprises transverse air channel and vertical air flue, and transverse air channel and vertical air flue are interconnected and form cross air flue, one end communication apparatus main body of vertical air flue, other end sealing; Spring and steel ball are arranged in transverse air channel, and one end of spring is fixed on the sidewall of transverse air channel, and the other end is connected with steel ball; The outer end of transverse air channel is connected with gas filling valve, and in junction, O-ring seal is set and seals.
Further, described aerating and exhaust device also comprises plug, and plug and gas filling valve outer end are threaded connection.
By the realization of technique scheme, gas-detecting device provided by the utility model, the in the situation that of change structure not, can freely be inflated and exit, and gas is changed, thereby effectively guaranteed the measuring accuracy of detector.
Accompanying drawing explanation
The structural representation that Fig. 1 is gas-detecting device that the utility model provides.
Embodiment
As shown in Figure 1, a kind of gas-detecting device, comprise apparatus main body 1, display screen 2, aerating and exhaust device, display screen 2 is arranged on the surface of apparatus main body 1, aerating and exhaust device is arranged on the below of apparatus main body 1, described aerating and exhaust device comprises spring 31, steel ball 32, air flue, O-ring seal 34, gas filling valve 35, plug 36, air flue comprises transverse air channel 33 and vertical air flue 37, transverse air channel 33 and vertical air flue 37 are interconnected and form cross air flue, one end communication apparatus main body 1 of vertical air flue 37, other end sealing; Spring 31 and steel ball 32 are arranged in transverse air channel 33, and one end of spring 31 is fixed on the sidewall of transverse air channel 33, and the other end is connected with steel ball 32; The outer end of transverse air channel 33 is connected with gas filling valve 35, and O-ring seal 34 is set in junction seals; Stifled 36 are threaded connection with gas filling valve 35 outer ends, and plug 36 can further seal aerating and exhaust device.
During inflation, screw out plug 36, connect extraneous source of the gas, gas enters after air flue 33 by gas filling valve 35, back down steel ball 32, Compress Spring 31, is able in access to plant main body 1 gas, after inflation finishes, spring 31 recovers former length, promotes steel ball 32 and pushes down O-ring seal 34, and then screw on plug 36; During venting, open plug 36, with a little bar, stretch in gas filling valve 35, prop up steel ball 32, force spring 31 compressions, the gas in apparatus main body 1 can be emitted; While usually working, can carry out by transparent display screen 2 variation of gas color in finder main body 1, thereby judgement equipment under test is in which kind of duty.
Claims (2)
1. a gas-detecting device, comprise apparatus main body, display screen, aerating and exhaust device, display screen is arranged on the surface of apparatus main body, aerating and exhaust device is arranged on the below of apparatus main body, it is characterized in that: described aerating and exhaust device comprises spring, steel ball, air flue, O-ring seal, gas filling valve, air flue comprises transverse air channel and vertical air flue, and transverse air channel and vertical air flue are interconnected and form cross air flue, one end communication apparatus main body of vertical air flue, other end sealing; Spring and steel ball are arranged in transverse air channel, and one end of spring is fixed on the sidewall of transverse air channel, and the other end is connected with steel ball; The outer end of transverse air channel is connected with gas filling valve, and in junction, O-ring seal is set and seals.
2. a kind of gas-detecting device as claimed in claim 1, is characterized in that: described aerating and exhaust device also comprises plug, and plug and gas filling valve outer end are threaded connection.
