Also, the lower end (end of-Z-direction) in umbrella portion 42 be set to the outside of shell 23, illumination with cover 25 with
Near the bond sites of radiating part 24.
It should be noted that umbrella portion 42 surrounds the periphery of shell 23 completely, but as long as enclosing coal gas detection portion 30, then
A part of the periphery of the shell 23 including coal gas detection portion 30 can only be surrounded.
Next, being illustrated to the fuel gas flow illuminated in one-piece type gas detectors 10.It should be noted that at this
In embodiment, the downside (- Z-direction) of guide portion 40 is formed as the entrance side of the space S between shell 23 and guide portion 40,
And the upside (+Z-direction) of guide portion 40 is formed as the outlet side of space S.
Lighting integrated type gas detectors 10 light emitting module 21 it is luminous when, heat is generated by light emitting module 21.Pass through
Illumination region 20 is set integrally to heat up by the generated heat that shines of the light emitting module 21.Therefore, if the air in space S is by luminous mould
The luminous heating of block 21, then expand and rise.New air flows into and is heated to rise from the lower end of space S as a result,.This
Sample, the air in space S are successively heated and rise, and the convection current of air is thus generated in space S.
In this state, indoors in the case where gas leakage, the combustion gas of leakage is due to lighter than air gradually to smallpox
Plate rises.As shown in figure 5, a part of the air containing the combustion gas having leaked reaches the entrance side of space S.As described above,
The convection current of air is generated in space S.Therefore, the also inflow space S of the air containing combustion gas.
The air containing combustion gas of inflow space S is heated supreme and the luminous generated heat by light emitting module 21
Temperature.Therefore, it generates from the downside of guide portion 40 (- Z-direction) towards the upside (+Z-direction) of guide portion 40 containing leakage
The convection current of the air of combustion gas.Downside (- Z-direction) the direction of the air containing combustion gas of inflow space S from guide portion 40 as a result,
The upside (+Z-direction) of guide portion 40 rises.As a result, the air containing combustion gas in space S be set to the outer of shell 23
The gas detectors 30 in week forcibly flow out while contact from the upside (+Z-direction) of guide portion 40.At this point, inflow space S
Combustion gas contacted with the coal gas detection portion 30 for the periphery for being set to shell 23, thus the combustion of 30 pairs of coal gas detection portion inflow space S
Gas is detected.By generating the upside (+Z-direction) flowing from the downside (- Z-direction) of guide portion 40 towards guide portion 40
Air convection current, the touch opportunity of the combustion gas of coal gas detection portion 30 and leakage can be made to increase, therefore can be improved leakage
The detection performance of combustion gas.
In addition, compared with the downside (- Z-direction) of guide portion 40, the shell 23 of illumination region 20 and the umbrella portion of guide portion 40
42 upside (+Z-direction) for being spaced in guide portion 40 is narrower, compared with the downside (- Z-direction) of guide portion 40, space S
Sectional area is smaller in the upside (+Z-direction) of guide portion 40.Therefore, the flow velocity of the air containing combustion gas of inflow space S with
The flow velocity of the air containing combustion gas when advancing and accelerate to the upside (+Z-direction) of guide portion 40, therefore being flowed out from space S
The flow velocity of the air containing combustion gas when can be than inflow space S is fast.By accelerating the flow velocity of the air containing combustion gas, can make
Coal gas detection portion 30 and the touch opportunity of the combustion gas of leakage further increase, therefore can further increase in coal gas detection portion 30
Combustion gas detection performance.
Even if coal gas detection portion 30 is in the periphery of shell 23 it is also preferred that be set to shell 23 contains driving circuit 22
Position.Light emitting module 21 it is luminous when, driving circuit 22 also generates heat.Therefore, because the heat of illumination region 20 and containing for rising
There is the air of combustion gas to be further heated by the heat generated by driving circuit 22, thus in the downside (- Z axis of guide portion 40
Direction) and upside (+Z-direction) between generate the air containing combustion gas temperature difference.Driving is contained in shell 23 as a result,
Near the position of circuit 22, the flow velocity of the air containing combustion gas can be further speeded up, therefore coal gas detection portion 30 can be easy
Detect combustion gas in ground.
Also, the lower end (end of-Z-direction) in umbrella portion 42 be set to the outside of shell 23, illumination with cover 25 with
