Its laser launched is received after gas absorption vessel 43 by laser absorption device 44.Laser generator 42 can fast modulation laser
Frequency simultaneously exports laser to scan the absorption line of measured target gas, and sensor 99 obtains target gas by detecting absorption spectrum
Body mass index.The gas of gas absorption vessel 43 determines frequency range by absorb that laser generator 42 launches laser line.
Photoelectric detector 46 be the controller that is made up of real-time control and the data handling system using single-chip microcomputer as core and
Semiconductor laser power supply forms, and it is used to the optical signal that laser absorption device 44 receives being converted to electric signal.
Analysis element 48 transmits the harmonic component in spectral line to analyze after being actually taken up by gas using techniques of phase-sensitive detecting technique measurement
The absorbing state of gas, obtain the air quality index in present air in real time.In the present embodiment, air quality index
For PM2.5 values.Result after analysis is sent to display element 49 and by display element 49 and shown by analysis element 48, allows user
The quality condition of air can be become apparent from sucking, to determine current practical action, meet the demand of hommization.
In summary, the tunable laser method in sensor 99 is modulated to light can avoid other gas componants to institute
The absorption line of selection produces interference, is not influenceed by dust and air pollution, performance comparision problem.Gas absorption vessel 43 is set
Air admission hole 432 and venthole are equipped with, the passage of air flow can be formed in sensor 99 so that the sensor 99 is in reality
While existing above-mentioned air quality index detects, moreover it is possible to reach the purpose taken a breath in real time.So, sensor 99 can be by not
Interruption ventilation improves air quality, user is absorbed new air to mitigate harm of harmful material to human body.
Fig. 5 to 7 is referred to, cover inner casing 120 is provided with accepting groove 122.Accepting groove 122 is from part cover inner casing 120 to away from cover
The direction of shell 110 is recessed to be formed.Sensor 99 is placed in accepting groove 122, while the opening of accepting groove 122 is as sensor
99 air inlet.Cover inner casing 120 is also provided with square chute 126 in the opening side of accepting groove 122, and square chute 126 is big
It is small not influenceed by the size of fan blade 30 of sensor 99.
Mouth mask 100 also includes the filter membrane bracket 200 being removably installed on the chute 126 of cover inner casing 120.Filter membrane
Bracket 200 is in tabular, and it can be slided with respect to chute 126 makes filter membrane bracket 200 to install into cover inner casing 120 and skid off cover
Switch between 120 two states of inner casing.
Please refer to Fig. 8 to 10, filter membrane bracket 200 is including being flat backing 220 and opening up lid 230.Backing
220 is generally rectangular shaped, the operating portion 224 that it includes backing main body 222 and the extension of backing main body 222 is formed.Backing main body 222 is opened
Provided with the rectangular recess 2220 placed for filter membrane.
Groove 2220 on the shape size and backing main body 222 of cover 230 is correspondingly arranged.In the present embodiment, hold in the palm
Lid 230 is rectangular.Cover 230 can be placed in the groove 2220 of backing main body 222, and passes through ultrasonic wave with backing main body 222
It is fixed together so as to which filter membrane is fixed in filter membrane bracket 200, makes filter membrane bracket 200 and filter membrane as a mistake
Filter structure is integrally assemblied on the cover inner casing 120 of cover body 130, facilitates user to change whole filter mechanism.
Operating portion 224 supplies user's push-and-pull to load and pull out cover inner casing 120 by filter membrane bracket 200.On operating portion 224
Facilitate user that filter membrane bracket 200 is pulled out into cover inner casing 120 provided with depressed part 2240 and change filter mechanism.Due to filter membrane bracket
200 be in tabular, and the replacing of filter mechanism can be directly completed by push pull maneuver, more convenient.
Further, the square chute 126 on filter membrane bracket 200 and cover inner casing 120 is correspondingly arranged so that cover inner casing
120 and filter membrane bracket 200 in the non-overlapping area of overthe openings of the accepting groove 122 of the air inlet as sensor 99, can be with
Farthest utilize the filter membrane in filter membrane bracket 200.
In addition, the backing 220 of filter membrane bracket 200 and opening up lid 230 and offering some through holes 225, do not reduced as far as possible
The filter area of filter membrane in filter membrane bracket 200.In addition, the Aspect Ratio of filter membrane bracket 200 is 16：9 golden ratio knot
Structure, relatively conventional exoskeletal or few skeleton structure, can preferably solve the problems, such as the support of filter membrane.
Concepts described herein may be embodied to other forms in the case of without departing from its spirit and characteristic.It is disclosed
Specific embodiment should be considered as exemplary rather than restricted.Therefore, the scope of the present invention be by appended claim,
Rather than it is determined according to these descriptions before.Any change in the letter of claim and equivalency range is all
The scope of these claims should be belonged to.
