Description
Technical field
The utility model relates to alcohol testing device field, exactly refers to a kind of alcohol tester with flux detecting function.
Background technology
Alcohol tester is for detection of the breathe out alcohol content of gas in body of user, if breath capacity not or the incorrect operation of breath all will affect the accuracy that detects result.Alcohol screen test is in the past the sampling of blowing when design, adopt the detection modes such as temperature detection to be confirmed whether that user is blowing, after can only detection temperature while blowing sampling whether reaching certain temperature, just sample, within when this detection mode user puffs away 1 second, by 2 seconds, just by constant, got off, for measurement capacity, be very difficult, capacity does not reach requirement, and the data that detect will cause inaccurate, thereby it is inaccurate to lose the test result of alcohol tester.
Utility model content
For above-mentioned defect, the technical matters that the utility model solves is to provide a kind of alcohol tester with flux detecting function, user's expiration is carried out to flux detecting, to guarantee to blow out the gas of enough capacity, so that alcohol tester can test out the interior alcohol concentration of measured's body more accurately.
In order to solve above technical matters, the alcohol tester with flux detecting function that the utility model provides, comprise tracheae, alcohol sensor and sampler, described tracheae is connected with described alcohol sensor, described alcohol sensor is connected with described sampler, also comprises microphone casing and microphone device, in described microphone casing, has microphone device, described microphone casing is connected with described tracheae by conduit, and described microphone device is arranged in described microphone casing.
Preferably, described microphone device comprises microphone amplifying circuit, main control module, sampling module, power module and display module, wherein, described microphone amplifying circuit is connected with described main control module, described power module is connected with described main control module, described display module is connected with described main control module, and described sampling module is connected with described main control module.
Preferably, described microphone amplifying circuit is arranged in described microphone casing.
