Embodiment
Defer to technique scheme, as shown in Figure 1 to Figure 3, this programme discloses a kind of hand-held device for detecting automotive interior harmful gas, comprise housing 12, housing 12 is provided with display screen 15 and keyboard 16 on the surface, in housing 12, be provided with airway 19, airway 19 top, bottom are respectively arranged with and the air intake opening 10 of housing 12 ft connection and gas outlet 7; Housing 12 inside is provided with air quality detector 8, and air quality detector 8 is connected with described display screen 15 and keyboard 16, and the probe 9 of air quality detector 8 extend in airway 19.
Mentality of designing of the present utility model is, existing in-car air quality monitoring device due to position be fixing, thus can only monitor the air quality in limited area, this data are subject to the impact of position.Such as, in car, jewelry easily distributes harmful gas, and when atmosphere quality monitoring device installation site is away from jewelry, the harmful gas concentration detected is just on the low side, and this is one sided.So this programme is considered and arranged the changeable detecting instrument in a kind of position, and carries out the detection of air quality when air flows, make the air regime that the air quality of detection can show in current vehicle objectively.
This programme entirety is handheld housing 12 equipment, and housing 12 is provided with display screen 15 and keyboard 16 on the surface.Housing 12 inside is provided with an airway 19, airway 19 has air intake opening 10 and gas outlet 7, there is air quality detector 8 in housing 12, existing equipment can be adopted, its probe 9 is placed in airway 19, concrete measuring principle is, make air in car enter into airway 19 from air intake opening 10 during use, and flow out from gas outlet 7, in this process, the air quality of air quality detector 8 to flowing detects, and the result of detection is shown by display screen 15; Keyboard 16 may be used for controlling air quality detector 8, and preserves Measuring Time and air quality data.The air of flowing is compared to static measurement, and measurement data is more accurate, and measuring process is very fast, can repetitive measurement, considers, determine current air mass situation after obtaining the data of repetitive measurement.
In order to be imported to by air in airway 19 better, in airway 19, air intake opening 10 place is provided with inducer 11; Inducer 11 can pass through electric power or manual actuation, make inducer 11 turn east under, can agitation air, make air flow through airway 19.
In order to as far as possible accurately obtain air quality data objectively in this programme, the airway 19 of inducer 11 bottom is divided into two parts by dividing plate 6, and air quality detector 8 can arrange two, and its probe 9 is placed in two parts respectively.Be divided into two parts by the air that inducer 11 blasts like this, detected respectively by an air quality detector 8, the two is detected after the data obtained are averaged and is shown by display screen 15, and this twin-channel test mode result is more accurate.
Inducer 11 is driven by drive unit and rotates, this programme is for convenience of using, the drive unit proposed comprises gas cell 1, wheel shaft 18 power wheel 17 that be connected coaxial with inducer 11 is provided with in described housing 12, above power wheel 17, be provided with guide duct 13, guide duct 13 is connected with gas cell 1.
The effect of gas cell 1 is for the rotation of inducer 11 provides power, and the gas velocity that gas cell 1 bloats is higher, be not suitable for for measuring, therefore power wheel 17 is provided with, the blade that the gas of what gas cell 1 provided have certain speed blows power wheel 17 makes it rotate, power wheel 17 rotates the inducer 11 that rear drive is arranged in airway 19 and rotates, and to make air flow through in airway 19, is convenient to testing process.
As shown in Figure 2, gas cell 1 is provided with air inlet termination 4 and termination 14 of giving vent to anger, in air inlet termination 4 and termination 14 of giving vent to anger, all retaining valve is installed; Described guide duct 13 is connected on air inlet termination 4.Retaining valve in the air inlet termination 4 of air bag only allows gas to enter into gas cell 1, and the retaining valve of giving vent to anger in termination 14 only allows gas to enter into guide duct 13.Gas cell 1 is elastic construction, can reset rapidly after pinching.In order to accelerate reseting procedure, gas cell 1 inside is provided with back-moving spring 2.
In use procedure, this device is extend into vehicle body, can the continuous pinching gas cell 1 of hand, make inner inducer 11 uniform rotation, blow air slowly flows through airway 19, carries out the measurement of air quality.After measurement, change a position and measure again.For ease of the use of whole device, housing 12 outer wall is provided with pair of brackets 5, support 5 is connected with air inlet termination 4, termination 14 of giving vent to anger by collar 3; And leave certain gap between gas cell 1 and housing 12.During use, can the finger of a hand through gap, hold gas cell 1, so both can facilitate pinching gas cell 1, whole device can be arrested again, very easy to use.
Although be below described embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art is under the enlightenment of instructions, and when not departing from the scope that the utility model claim is protected, can also make a variety of forms, these all belong to the row of protection of the present utility model.
