Abstract
The open a kind of dust laser sensor of this utility model, including optical measurement cavity and exhausting system, it is characterised in that: also including that drainage screen, described optical measurement cavity are provided with an air inlet, described drainage screen shape is adaptive with air inlet；Described drainage screen includes filter screen bracket and nylon wire.The drainage screen that this utility model provides, uses nylon wire material, can conveniently take out cleaning, cleaning after filter screen dust, sensor accuracy class can be made to recover, prolongation sensor service life.
Description
Technical field
This utility model relates to air detection field, particularly relates to a kind of dust laser sensor.
Background technology
In recent years, along with the raising of quality of life, people are more and more higher to the concern of air quality, dust laser sensor
As can quick and precisely detect the electronic product of air quality, it is widely applied to above environment measuring and household electrical appliances.But at present
On market, the laser sensor life-span is the shortest, and reason is the accumulation along with dust, and optical measurement tracavity optical components and parts can be slowly
Lose precision, until thoroughly losing efficacy..
Utility model content
This utility model aims to provide a kind of dust laser sensor, reduces the mistake that sensor produces because of dust pollution
Effect.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
A kind of dust laser sensor, including optical measurement cavity and exhausting system, also includes drainage screen, and described optics is surveyed
Amount cavity is provided with an air inlet, and described drainage screen shape is adaptive with air inlet；Described drainage screen includes filter screen bracket and nylon wire.
Preferably, described filter screen bracket is quadra, has a divider, divider and quadra in the middle of quadra
Minor face parallel.
Preferably, described drainage screen is connected by grab draw-in groove with air inlet.
Preferably, described air inlet is provided with draw-in groove, and described filter screen bracket is provided with grab.
Utility model works principle is as follows: under exhausting system works, air to be measured arrives optical measurement again through drainage screen
Chamber, big dust particle, when through drainage screen, can be blocked on filter screen, reduces the dust pollution to optical measurement cavity, can have
Effect extends the sensor optical certainty of measurement life-span.
The drainage screen that this utility model provides, uses nylon wire material, can conveniently take out cleaning, is cleaning filter screen dust
Afterwards, sensor accuracy class can be made to recover, extend sensor service life.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is filter screen structure schematic diagram
In figure: 1-drainage screen, 2-optical measurement cavity, 3-exhausting system, 4-nylon wire, 5-filter screen bracket.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, to this reality
It is further elaborated with novel.
As depicted in figs. 1 and 2, a kind of dust laser sensor, including optical measurement cavity 2 and exhausting system 3, also include
Drainage screen 1, described optical measurement cavity 2 is provided with an air inlet, and described drainage screen 1 shape is adaptive with air inlet；Described drainage screen 1
Including filter screen bracket 5 and nylon wire 4.
Preferably, described filter screen bracket 5 is quadra, has a divider, divider and square box in the middle of quadra
The minor face of frame is parallel.
Preferably, described drainage screen 1 is connected by grab draw-in groove with air inlet.
Preferably, described air inlet is provided with draw-in groove, and described filter screen bracket 5 is provided with grab.
Utility model works principle is as follows: under exhausting system works, air to be measured arrives optical measurement again through drainage screen 1
Chamber 2, big dust particle, when through drainage screen 1, can be blocked on drainage screen 1, reduces the dust dirt to optical measurement cavity 2
Dye, can effectively extend the sensor optical certainty of measurement life-span..
Certainly, this utility model also can have other various embodiments, spiritual and essence without departing substantially from this utility model
In the case of, those of ordinary skill in the art can make various corresponding change and deformation according to this utility model, but these phases
Change and the deformation answered all should belong to the scope of the claims appended by this utility model.
