<embodiment one>
As shown in Figures 1 to 4, the toxic gas detection safety cap in the present embodiment, including safety cap and warning device,
In: the safety cap includes cap body 1100 and chin strap 1200, and shield jaw block 1210, the shield are equipped in the middle part of the chin strap 1200
Several ventholes 1211 are provided on jaw block 1210；
The warning device includes detection sensor 2100, warning lamp 2200, processing module 2300 and battery module
2400, the detection sensor 2100 is set in the shield jaw block 1210, and the warning lamp 2200 is set to the cap body
1100 lower section of the brim of a hat 1110, the processing module 2300 and the battery module 2400 be fixed on the cap body 1100 with institute
It states on the outside of the opposite one end of the brim of a hat 1110.
In the present embodiment, detection sensor 2100 is disposed in proximity to the position of mouth and nose, can more accurately supervise
The concentration of toxic gases for surveying human body sucking gas, prevents the distribution difference of toxic gas from leading to missing inspection and sucking human body, and
The air-flow that human body respiration generates can also help the diffusion of gas, and detection sensor 2100 is made more to be quickly detected current location
Concentration of toxic gases；Warning lamp 2200 is set under the brim of a hat 1110, convenient for observation, prevents mine or pipe network intraoral illumination too bright
Influence observation.
In the present embodiment, detection sensor 2100 can be the detection sensor of pure gas, be also possible to incorporate
The integrated circuit of multiple gases detection sensor.
In the present embodiment, the warning lamp 2200 includes two, is respectively arranged at the two of 1110 center line of the brim of a hat
Side, the distance of two warning lamps 2200 are equal to the distance of two eyes of human body.Two warning lamps 2200 are set, reliability is improved；
The crowd bad suitable for some single eye eyesights.Since the air therapeutic in mine or pipe network is poor, there are many dust, powder
Dirt, which is easily accessible in eyes, causes some eye temporarily uncomfortable, therefore two warning lamps 2200 are arranged and are conducive to further increase this
The reliability of device, each eye are able to observe that warning lamp 2200.Warning lamp 2200 is two from blinking light emitting diode
Warning lamp 2200 can be same color, or different colours alternately flash.
In the present embodiment, the venthole 1211 is set to the front end of the shield jaw block 1210, the venthole 1210
It is inside provided with metal filter screen (not shown), prevents dust from entering the detection accuracy for influencing detection sensor 2100.
In the present embodiment, the side of the shield jaw block 1210 is again provided with venthole 1211, the shield jaw block 1210
It is inside provided with fan 2110, the fan 2110 improves air flowing towards the venthole 1211 of shield 1210 side of jaw block
Speed prevents venthole 1211 from influencing detection effect because of the blocking of dust.
In the present embodiment, the warning device further includes two loudspeakers 2500, and the loudspeaker 2500 is respectively set
In the bottom of 1100 two sides of cap body, loudspeaker 2500 is set to 1100 liang of side bottoms of cap body, can be clear close to ear
Alarm sound is not heard, and does not block ear, does not interfere personnel transfer.Loudspeaker 2500 is controlled by processing module 2300, if inspection
It measures concentration of toxic gases and reaches certain standard, play Audio Alert, or play concentration of toxic gases.
In the present embodiment, the battery module 2400 is two pieces of lithium ion batteries 2410, is set to the processing module
Battery 2410 is placed in bottom rearward position by 2300 two sides, avoids top and rear end upper position is often collided with
Position prevents battery 2410 from colliding with, causes short circuit risk.
The present embodiment has technical effect that, will test sensor 2100 and is arranged close to nose, when detection breathes in air-flow
Concentration of toxic gases, improve reliability；Warning lamp 2200 and loudspeaker 2500 are arranged respectively close to eyes and ear, adapt to
Warning note under complex environment.
<embodiment two>
As shown in figure 5, the toxic gas detection safety cap in the present embodiment is compared to above-described embodiment, difference exists
In the warning device further includes vibrator 2600, and the vibrator 2600 is set to the shield jaw block 1210 and the cap body
On chin strap 1200 between 1100.
Due to often having biggish noise and stronger illumination light in working environment, merely simultaneously by sound-light alarm
It can not effectively remind construction personnel, be provided with vibrator 2600 close to face in the present embodiment, detecting poison gas
When body other than sound-light alarm, vibration can be also generated, since pudendal nerve is more sensitive, can effectively remind constructor
Member, further increases the reliability of the present apparatus.
Although being described in detail by some specific embodiments of the example to the utility model, this field
It is to be understood by the skilled artisans that above example merely to be illustrated, rather than in order to limit the scope of the utility model.This
Field it is to be understood by the skilled artisans that can not depart from the scope of the utility model and spirit in the case where, to above embodiments
