Description

Dust sensor
Technical field
The present invention relates to a kind of dust sensor.
Background technology
Some automobiles judge air quality within the interior or exterior of the vehicle equipped with air borne sensor.This sensor main will be by Fans drive air flow, then emitted beam by the luminous tube in sensor, through corresponding detection zone, received by reception pipe Signal, obtains data.
But, existing sensor is only limited to test data within the interior or exterior of the vehicle, it is impossible to while obtaining the air outside in-car Qualitative data, and then when cannot judge that air quality is relatively low in the car, if the window that to drive is (when in-car air quality is less than car Outward) or turn on the aircondition (when in-car air quality is higher than outside car).And if to obtain the related data outside in-car simultaneously, then need to install Two sensors.
The content of the invention
The technical problem to be solved in the present invention is:In order to overcome the existing air borne sensor cannot be while obtaining car inner air and outer air The deficiency of qualitative data, the present invention provides a kind of dust sensor.
The technical solution adopted for the present invention to solve the technical problems is:A kind of dust sensor, including fan and sensing Device body, the sensor body includes in-car air channel, car outer air duct, luminous tube, optical lens group and reception pipe, the in-car Air channel and car outer air duct are mutually isolated;The in-car air channel has in-car tunnel inlet and in-car ducting outlet, the car exogenous wind There is car outer air duct entrance and car outer air duct to export in road;The in-car ducting outlet and the outlet of car outer air duct are close to each other, or In-car ducting outlet and the outlet of car outer air duct are same through hole, and the fan sets ducting outlet in the car and car outer air duct is exported Place;The reception pipe includes being respectively provided with the interior reception pipe and outer reception pipe of air channel in the car and car outer air duct, the in-car wind Road and car outer air duct are arranged side by side, and the emitting light path of the luminous tube is divided into two bursts of light paths and injects car respectively by optical lens group Interior air channel and car outer air duct, the interior reception pipe and outer reception pipe deviate light path and are respectively provided with air channel in the car and car outer air duct.
The present invention can be realized only with one group of fan and luminous tube, while obtaining the air dependency number outside in-car and car According to.Therefore, devising passage and car outer tunnel, this two paths is mutually isolated, therefore, in-car car outer ventilation circuit is not done mutually Disturb.Meanwhile, emitted beam using same luminous tube, inject passage and car outer tunnel respectively by optical lens group, can Ensure the accurate of relative data.The setting of fan causes that sensor is inside and outside and produces pressure differential, and then promotes extraneous air to enter biography Inside sensor.And in-car ducting outlet and car outer air duct export close to each other or are same through hole so that the outlet of two-way wind path Same fan can be set, i.e., internal wind field is to be rotated to produce by same fan, ensure that two measured zone wind field numbers According to stabilization.The emergent ray of luminous tube can be infrared ray or laser.
In-car air channel and car outer air duct, the optical lens are not injected in order to the emergent ray for realizing luminous tube is divided into two stocks Microscope group includes spectroscope and is separately positioned on two pieces of speculums of spectroscope both sides, the luminous tube towards spectroscope, the hair The emitting light path of light pipe is divided into two strands and is parallel to each other or after collinear light path by spectroscope, anti-by two pieces respectively Mirror is penetrated to reflect into in-car air channel and car outer air duct.
A kind of implementation method is that the spectroscope and speculum are total reflection prism.
Specifically, preferably, the in-car air channel and car outer air duct are symmetrically set, the luminous tube is located at in-car On the symmetry axis of air channel and car outer air duct.In such manner, it is possible to ensure the light path correlation of in-car air channel and car outer air duct well, more Be conducive to the outer comparing of in-car car.
In order to collect the data close to air quality within the interior or exterior of the vehicle, the interior reception pipe is located at in-car tunnel inlet Near, the outer reception pipe is located at car outer air duct entrance.
In order that in-car air channel and car outer air duct form unique wind path in entrance to the exit of wind so that air is more Close to the air quality entered before air channel, the in-car air channel has the first wind deflector, and car outer air duct has the second wind-guiding Plate, and the first wind deflector and the second wind deflector are bending-type baffle plate, first wind deflector prolongs always from by in-car tunnel inlet Extend at in-car ducting outlet, second wind deflector extends to car outer air duct exit from by car outer air duct entrance.
In order to prevent light path from reflecting, the reception light of reception pipe is influenceed, and then influence collection result, first wind deflector With path channels hole, the light that the path channels hole position reflects in luminous tube by optical lens group are offered on the second wind deflector Lu Shang.So so that light can be projected after being reflected by optical lens group by path channels hole, and then from in-car air channel Projected with car outer air duct.
The fan is one, and in-car ducting outlet and the outlet of car outer air duct are same through hole, the in-car air channel and car Outer air duct is mutually isolated by dividing plate, and the dividing plate is arranged on the through hole to form in-car ducting outlet and the outlet of car outer air duct. Internal wind field is to be rotated to produce by same fan, ensure that two stabilizations of measured zone wind field data.Meanwhile, in-car wind Road is exported and the outlet of car outer air duct is same through hole, dividing plate air channel and while car outer air duct in runner wagon, can be separated again Go out in-car ducting outlet and the outlet of car outer air duct, simplify the processing of in-car ducting outlet and the outlet of car outer air duct.
In order to obtain the signal of reception pipe, also including circuit board and connector, the luminous tube and reception pipe are and circuit Plate is connected, and the circuit board connects external power source by connector.
In order to protect component, also including upper lid, the upper lid lid is located on sensor body, and the circuit board is located at sense Answer between device body and upper lid.
The beneficial effects of the invention are as follows dust sensor of the invention can simultaneously obtain the air phase outside in-car and car Close data.Passage and car outer tunnel are mutually isolated, do not interfere with each other in-car car outer ventilation circuit.Meanwhile, using same luminous Pipe emits beam, and injects passage and car outer tunnel respectively by optical lens group, it is ensured that relative data it is accurate.Fan Setting cause that sensor is inside and outside and produce pressure differential, and then promote extraneous air to enter sensor internal.And in-car ducting outlet It is close to each other or be same through hole with the outlet of car outer air duct so that the outlet of two-way wind path can set same fan, i.e., internal Wind field is to be rotated to produce by same fan, ensure that two stabilizations of measured zone wind field data.
