Beneficial effect: the utility model compared with prior art, can control in time exhaust mercury and discharge test gas residual in alcohol testing device and control cleaning unit residual residual spot is cleaned by described alcohol testing device.Thereby ensure the accuracy while again testing, and health while ensureing again to test.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model alcohol testing device.
Embodiment
Below in conjunction with embodiment, the utility model is further described.
As shown in Figure 1, a kind of alcohol testing device of the utility model specific embodiment, described alcohol testing device comprises air intake opening 1, alcohol gas sensor 2, the first gas outlet 3, the second gas outlet 4, exhaust mercury 5, cleaning unit 6 and single-chip microcomputer (not shown), and wherein cleaning unit 6 comprises the water injector 61, cleaning part 62, telescopic connecting link 63 and the micromachine 64 that are arranged at cleaning unit 6 tops; The junction of air intake opening 1 and the first gas outlet 3 is provided with the first electrovalve 31, the junction of air intake opening 1 and the second gas outlet 4 is provided with the second electrovalve 41, and described single-chip microcomputer is connected with alcohol gas sensor 2, the first electrovalve 31 and the second electrovalve 41 respectively.
The principle of work of the utility model alcohol testing device:
When driver is carried out to alcohol screen test, driver blows to air intake opening 1, gas enters alcohol gas sensor 2 through air intake opening 1, alcohol gas sensor 2 is transferred to single-chip microcomputer by A/D interface by surveyed gas alcohol concentration, and single-chip microcomputer carries out numerical value demonstration by display (not shown).Single-chip microcomputer is after numerical value shows a period of time, first controlling the first electrovalve 31 opens, and control exhaust mercury 5 simultaneously and carry out work, residual gas in alcohol gas sensor 2 is discharged, then open the second electrovalve 41, and control micromachine 64 promotes telescopic connecting link 63 makes its cleaning part 62 clean residual alcohol and steam etc. on alcohol gas sensor 2 sidewalls, and open water injector 61 to spraying water on alcohol gas sensor 2 sidewalls, to clean better alcohol gas sensor 2 simultaneously.
To the explanation of disclosed above-described embodiment, make those skilled in the art can realize or use the utility model, the those skilled in the art of amendment team to above-described embodiment are apparent, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model is not restricted to embodiment illustrated herein, but will meet the wide region consistent with principle disclosed herein and features of novelty.
