Description
Technical field
The present invention relates to a kind of fine particle concentration detection device more particularly to a kind of the function is realized using mobile phone component
Device.
Background technique
Particulate matter refers to various solids and liquid particle evenly dispersed in aerosol system, including primary particulate and two
Secondary particulate matter.Primary particulate is the particulate matter polluted of being discharged into the atmosphere by direct pollution sources, secondary aerosol species be by
Reacted between certain contaminating gaseous components or between these components and the normal components in atmosphere by photochemical oxidation in atmosphere,
The particulate matter that catalytic oxidation or other chemical reactions are converted into.Atmospheric particulates are mainly what natural pollution source generated,
But big city and the industrial and mining area of some areas such as population concentration, the quantity artificially generated is relatively more, including three macrofossil fuel, life
The primary particulate of the direct emissions such as the burnings such as substance and road and building fugitive dust, industrial dust, also including primary emission
After the secondary aerosol species that gaseous pollutant is transformed, especially the 1950s, industry, traffic are grown rapidly, population
It increasingly concentrates, city more expands, the great increase of fuel consumption, and Particulate Pollution caused by artificial origin is on the rise.Greatly
Aerated particle can be suspended in the air the long period, portable poisonous and harmful substances, and particle sinking speed is slow and conveying distance
Far, and the physiological structure of human body determines its filtering and stops the effect of Atmospheric particulates limited, therefore Atmospheric particulates are to people
The influence of body is very big.The method of measurement particle concentration mainly has gravimetric method, light scattering method, concentration specifications table comparison method, luminosity
Mensuration and particle calculating method.Domestic most common detecting instrument is the laser dust monitor produced using light scattering method at present, with
And the portable particulate matter sensors using light scattering method production, measuring device is more complicated, needs additional power supply and circuit
Plate and communication module, in order to solve these problems, the present invention utilize the processor and power supply of mobile phone itself, provide a kind of knot
Structure is simple and the higher fine particle concentration detection device of precision.
Summary of the invention
The invention discloses a kind of fine particle concentration detection devices, which includes mobile phone body and optical path component, in hand
Sensitive device and light source are provided on owner's body, sensitive device and light source are powered by battery of mobile phone, and the light that light source generates passes through light
Road component simultaneously eventually arrives at sensitive device, and the analog signal that sensitive device generates is handled by cell phone processor, then in mobile phone
It is shown in application APP.Optical path component contains optical lens and reflecting mirror, and the light that light source generates passes through optical lens front end,
Optical path component is designed to telescopic.The invention saves individual power supply, circuit board and bluetooth communication, while optical path component
Telescopic design make more compact structure, it is more portable.

Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, disclose further below some non-
Limiting embodiment, the present invention is described in further detail.
As shown in Figure 1, the device includes mobile phone body 1, mobile phone the invention discloses a kind of fine particle concentration detection device
Sensitive device 11 and light source 12 are provided in main body 1, sensitive device 11 and light source 12 are powered by mobile phone body 1.
As shown in Figures 2 and 3, the invention discloses a kind of fine particle concentration detection device, which further includes optical path group
Part 2, optical path component 2 are equipped with reflecting mirror 24 and optical lens 25, and the optical signal that light source 12 issues is reflected through reflecting mirror 24 in optics
On the fine grained 3 of 25 front of lens, after fine grained 3 emits optical signal again, amplified by optical lens 25, finally quilt
Sensitive device 11 receives.The mobile phone body provides the electric energy of sensitive device 11 and light source 12, the received light of sensitive device 11 letter
It number is handled by 1 built-in integrated circuit of mobile phone body, is then calculated by the processor in mobile phone body 1, and
Fine particle concentration is shown in the application APP of mobile phone body 1.
As shown in Figures 2 and 3, optical path component 2 is additionally provided with chopped-off head casing 21, at least one intermediate casing 22, end casing
23, chopped-off head casing 21, intermediate casing 22 are sequentially connected and mutually nested with end casing 23, are realized the flexible of optical path component 2, are made
It is proper do not need using when optical path component 2 is retracted, optical path component 2 is stretched out when it is desired to be used, the beneficial effect is that subtracting
Few mobile phone occupied space, is convenient for carrying, at the same also protect optical path component 2 do not need using when avoid by extraneous dirt
Dye.
As shown in figure 4, optical path component 2 is when need to use in a kind of fine particle concentration detection device disclosed by the invention
The state of stretching, extension.
As shown in figure 5, in a kind of fine particle concentration detection device disclosed by the invention, optical path component 2 do not need using
When the state packed up, convenience easy to carry and Backup lightpath component 2.
