Enough flow velocitys for preferably stablizing air pump 31, this just preferably ensure that the gas surveyed in haze chamber 22 can have relatively stable stream
Speed, and then preferably ensure that the accuracy of DATA REASONING.
Survey haze instrument body 100 in the present embodiment also includes plastic casing, and plastic casing includes lower cover 35 and upper casing 10, under
Lid 35 is fixedly connected with upper casing 10.Screen display device includes screen circuit board 8, screen 9, Transparent frame 11 and shift knob 12,
Screen circuit board 8 is connected with screen 9, and screen 9 is fixed on the surface of upper casing 10 by Transparent frame 11, and shift knob 12 is installed on upper casing
On 10.
Be additionally provided with cell apparatus in addition, surveying in haze instrument body 100, with reference to shown in Figure 19, cell apparatus include lithium battery 36,
Battery bracket 37 and USB charging heads 43, lithium battery 36 are installed on battery bracket 37, and lithium battery 36 is filled by USB charging heads 43
Electricity, screen circuit board 8 are powered by lithium battery 36.It is convenient that cell apparatus is charged by carrying with charging wire.
The present invention is run by air pump 31 and produces air-flow, and the air of Particulate Inclusion thing is pumped into cutter 1, passes through two ranks
The cutting of section, enter the air for being substantially free of remaining (with phase to be measured repulsion) particles things and survey in haze chamber 22.Then it is red
Outer laser generating assembly 27 irradiates particulate matter, and particulate matter receiving unit 26 amplifies particulate matter and receives calculating, specifically by
Infrared laser pipe 51 irradiates the particulate matter entered in survey haze device to come, then the second lens for passing through particulate matter receiving unit 26
60 amplification, then by receive sensor 59 receive calculate, computational methods be by laser irradiate projected area, weigh supplemented by
Help.Then can be adsorbed after particle analyte detection is complete on filter for installation, the filter membrane in filter for installation is removable to unload title particle down
The weight of thing.Do not allow particulate matter to enter in air pump 31 it can in addition contain play, protect air pump 31.Three-in-one sensor device and
Five in one sensor device device is connected on main circuit board 7 by socket, and detection data are shown finally by screen display device.
The mass figures of energy quick detection air of the invention, fast response time, are advantageous to grasp air quality in time, so as to
Effectively improve furniture environment, or carry out protected working, there is ageing and operability.It is convenient for carrying, it is simple to operate bright
, it is singlehanded just easily to control, detection work is carried out whenever and wherever possible, it is rationally strong to oneself according to different degrees of environmental pollution
The residence row suggestion of health.And by carrying with charging wire, the charging of USB charging heads is more convenient, longevity of service, has well
Environmental suitability, it is applied widely.The mode that the cutter of the present invention is fixed on rotation is stuck on survey haze device, on survey haze chamber
Fixed screw unclamp slightly, then cutter is screwed into fixed screw clockwise, fixed screw locked again after being screwed into position
Tightly, in order to avoid gas leakage.Other end absorption glass falls light absorbs after infrared laser irradiation of the present invention, in case light fires back, such as
Fruit light reflects the detection that will influence particulate matter.The present invention is cased with second spring outside screw, realizes that filter fills
Put to be locked in and survey on haze chamber, filter for installation is withstood by second spring, because filter for installation just needs to change after a while, directly
Connect and open filter membrane cover plate with regard to filter for installation can be changed from the hole surveyed on haze chamber with the thimble top of specialty.
Schematically the present invention and embodiments thereof are described above, this describes no restricted, institute in accompanying drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So if common skill of this area
Art personnel are enlightened by it, without departing from the spirit of the invention, without designing and the technical scheme for creativeness
Similar frame mode and embodiment, protection scope of the present invention all should be belonged to.
