Abstract
The utility model discloses a blowpipe for breath alcohol content tester, comprising a blowpipe body, wherein a through-hole connected with a pressure sensor and a through-hole connected with an alcohol sensor are arranged on the side-wall of the body, a baffle plate is longitudinally arranged in the blowpipe between the two through-holes, a gas-flow hole is arranged in the middle of the baffle plate and the gas-flow flows from the direction near the pressure sensor through-hole to the direction near the alcohol sensor through-hole. The blowpipe for breath alcohol content tester can satisfy the needs of people to the measurement of breath pressure and alcohol content, and make the use more convenient and the measurement more accurate.
Description
Technical field
The utility model relates to a kind of alcoholicity of exhaled gas tester, the particularly blow tube construction of alcoholicity of exhaled gas tester.
Background technology
The police comes the alcohol content of test drives person in breathing by the alcoholicity of exhaled gas tester, thereby judge whether the driver drives when intoxicated, the existing employed alcoholicity of exhaled gas tester of people, its structure all is directly to be connected with the alcoholicity of exhaled gas tester by a blow gun or mouthpiece, the gas of breathing out directly acts on alcohol sensor, the monitoring of carrying out is owing to be subjected to the influence of air temperature and current intensity in this case, not only test not accurate enough, and damage sensor easily, influence accuracy of measurement and sensor serviceable life of whole tester, shortcoming at prior art, the applicant has invented a kind of detected pressures of passing through, make air-flow stably enter the tester of alcohol sensor, how to design at can detected pressures, can detect the employed incoming call gas apparatus of tester of alcohol content again, be the problem that needs solution at present.
The utility model content
At the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of alcohol content tester blowpipe, and this can satisfy the needs of detected pressures and alcohol, and result of use is better.
The technical solution adopted in the utility model is: a kind of alcoholicity of exhaled gas tester blowpipe, it comprises the blowpipe body, on the sidewall of described body, offer through hole that is connected with pressure transducer and the through hole that is connected with alcohol sensor, be vertically arranged with baffle plate in the blowpipe body between two through holes, centre at described baffle plate is provided with airflow hole, and air-flow is from flowing to the direction of close alcohol sensor through hole near the direction of pressure transducer through hole.
The described through hole that is connected with pressure transducer and with through hole that alcohol sensor is connected between the blowpipe body on be provided with thickened section.
Described baffle plate is arranged on the position near the pressure transducer connecting through hole.
The described through hole that is connected with pressure transducer stretches out from described blowpipe body respectively with the through hole that is connected with alcohol sensor and forms hollow tubing string, and the described flexible pipe that is connected with alcohol sensor with pressure transducer is connected on the described tubing string.
Be outside equipped with four locating pieces at described through hole that is connected with pressure transducer and the through hole that is connected with alcohol sensor.
Described locating piece is a right-angle triangle, and the right angle of described each locating piece is inwardly corresponding to be provided with.
On described body, be provided with the groove that shows the air blowing direction.
Alcoholicity of exhaled gas tester blowpipe of the present utility model, on body, offer through hole that is connected with pressure transducer and the through hole that is connected with alcohol sensor, because air-flow is from flowing to the direction of close alcohol sensor near the direction of pressure transducer through hole, therefore, air-flow is introduced into pressure transducer and tests, satisfy the needs of pressure transducer, in addition, owing to be vertically arranged with plate washer in the blowpipe between two through holes, centre at baffle plate is provided with airflow hole, like this, milder when making the air-flow process through hole in the blowpipe, detect better effects if.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Embodiment
Shown in Fig. 1-4, alcoholicity of exhaled gas tester blowpipe of the present utility model, comprise blowpipe body 1, on the sidewall of body 1, offer through hole 2 that is connected with pressure transducer and the through hole 3 that is connected with alcohol sensor, through hole 2 and through hole 3 stretch out from body 1 respectively and form hollow tubing string 4 and 5, the flexible pipe that is connected with pressure transducer is connected on the hollow tubing string 4, the flexible pipe that is connected with alcohol sensor is connected on the hollow tubing string 5, be vertically arranged with baffle plate 6 in the blowpipe body 1 between through hole 2 and 3, be provided with airflow hole 7 in the centre of baffle plate 6, on the blowpipe body 1 between through hole 2 and the through hole 3, be provided with thickened section 8, thickened section can play the function of anti-aqueous vapor, and waterproof sucks detection system.Baffle plate 6 is arranged on the position near through hole 2.Air-flow is from flowing to the direction of close alcohol sensor through hole 3 near the direction of pressure transducer through hole 2.This design makes the air-flow that enters through hole 2,3 more gentle, and it is more accurate to monitor.
The location is being outside equipped with four locating pieces 10 with through hole and the through hole that is connected with alcohol sensor for convenience.Locating piece 10 is a right-angle triangle, and the right angle of each locating piece is inwardly corresponding to be provided with.On body 1, be provided with and show the groove 9 that blows afloat direction.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
