Go out, the laser of laser module 22 passes through air flue, and the dust particle scattering light in air flue feeds back to photodiode, photodiode
Potential change is handled by circuit data and obtains PM2.5 numerical value.
As shown in figure 20, two wind turbines 3 are arranged in the utility model binary channels air quality detecting device, and two wind turbines 3 divide
The other air to outside interior and vehicle samples, and is mutually independent of each other, and can effectively reduce when air-conditioning is opened to module samples air-flow
Influence, ensure detection precision.Also, the transmitting terminal of two laser modules 22 is arranged the utility model in outer eight-shaped, no
But the longitudinal length that can effectively reduce the air detection module, reduces the overall volume of product.
Secondly, the utility model can meet full-automatic assembly technology, by the top needle connector 371 and air quality of wind turbine 3
It detects the hard contact 251 of module 2 and the conductive contact 41 on master control PCB4 plates and pin 42 is mating, can increase substantially
Production and packaging efficiency, facilitate inspection and repair.
Furthermore the outlet air end of the first wind turbine 3A and the second wind turbine 3B of the utility model connect noise-reduction joint 6, suction
Greatly, the experience of user can be improved in low noise.Wind turbine sealing cover 38 is closed in the upper cap of Fan casing 31, the lower part of Fan casing 31 is set
The noise generated when the first wind turbine 3A and the second wind turbine 3B work can effectively be reduced by setting fan shock-absorbing pad 39.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
