A gas cylinder 132 is connected to the other end of the tube 42, and a combustible gas is supplied to the injection unit 40 from the gas cylinder 132 via the tube 42. In the first embodiment, the tube 42 is accommodated inside the support rod 110. However, the tube 42 may be attached along the outer periphery of the support rod 110.

The holding part 30 is formed in a U-shaped cross section by bending a metal plate such as an aluminum plate. The holding part 30 includes support parts 30a and 30b and a bottom part 30c. The bottom portion 30 c is fixed to the bottom surface 62 a of the case 60. A through hole 30d is formed in the bottom 30c, and the injection unit 40 is fitted into the through hole 30d. Attachment holes 32a and 32b are formed at positions where the support portions 30a and 30b face each other. Hollow screws 70a and 70b are screwed into the mounting holes 32a and 32b. The support portions 30a and 30b support both side surfaces of the heat generation unit 20 via screws 70a and 70b so that the heat generation unit 20 is positioned in the injection direction of the injection unit 40.

The heat generating unit 20 generates heat by reaction heat due to oxidative decomposition of the combustible gas using a catalytic action. The heat generating unit 20 has a hollow cylindrical housing 20a made of a metal such as aluminum. The housing 20a has a heat generation chamber 80 in which flammable gas is oxidatively decomposed.

The temperature of the platinum net 26 is increased to the activation temperature by the combustible gas fuel, whereby the catalytic action of the platinum net 26 is promoted in the heat generation chamber 80. Due to the catalytic action of the platinum mesh 26, the combustible gas is oxidatively decomposed in the heat generation chamber 80, and heat of reaction due to oxidative decomposition is generated. Due to the heat generated by the heat generation unit 20, the ambient temperature of the heat generation unit 20 rises, and the operation test of the heat sensor 210 is performed.

Further, the combustible gas injected from the injection unit 40 liquefies the water vapor in the case 60 by evaporative cooling, and the water vapor liquefied in the case 60 is filled with smoke. An operation test of the smoke detector 200 is performed by the smoke.

As described above, the combustible gas is injected from the injection unit 40, and a part of the combustible gas is taken into the heat generation chamber 80 through the flame extinguishing element 22a. However, the combustible gas is not all taken into the heat generation chamber 80 but diffuses to the outside of the heat generation unit 20. Therefore, smoke is generated by the other combustible gas existing in the case 60 besides the smoke generated by the liquefaction of the water vapor discharged from the heat generation chamber 80 through the flame extinguishing element 22b. Note that the case 60 may not be provided.

Further, a switch may be provided in the operation unit 120 and the three-way valve 90 may be switched by the switch. Further, the first branch gas pipe 44-1 or the second branch gas pipe 44-2 may be supported by support members from both sides and fixed to the base 92.

The heat generating unit 20 is installed via the holding unit 30 in the injection direction 300 of the first injection unit 40-1. Since the structure of the heat generating unit 20 may be the same as that of the heat generating unit 20 of the first embodiment, detailed description thereof is omitted.

With the above configuration, the combustible gas injected from the injection port 40a-1 of the first injection unit 40-1 is taken into the heat generating unit 20 and reacted by oxidative decomposition of the combustible gas using a catalytic action.

The main body 100 according to the third embodiment differs from the main body 100 according to the first embodiment in that the injection direction of the injection unit 40 is switched and the case 60 is not provided.

A base 92 made of a metal plate such as an aluminum plate is joined to the tip of the support rod 110 as in the second embodiment. An opening 92 a is formed at a position corresponding to the support rod 110 of the base 92. The support parts 30a and 30b which comprise the holding | maintenance part 30 hold | maintain the heat generation part 20 similarly to 1st Example. Furthermore, extending portions 30e and 30f are formed in the support portions 30a and 30b, respectively, and guide grooves 30g and 30h are formed in the extending portions 30e and 30f. The extension portions 30e and 30f support the injection portion 40 so as to be rotatable around the rotation shaft 48 along the guide grooves 30g and 30h. That is, the extension parts 30e and 30f and the rotating shaft 48 function as an injection direction switching part that switches the injection direction of the injection part 40.

Moreover, the injection unit 40 and the base 92 are joined via a leaf spring (not shown) having elasticity. Furthermore, one end of a wire 94 is connected to the injection unit 40. The wire 94 passes through the inside of the support rod 110 through the opening 92 a and extends to the operation unit 120, and the other end of the wire 94 is connected to a lever (not shown) provided in the operation unit 120. By operating the lever, the wire 94 is pulled toward the operation unit 120.

The injection part 40 is connected to one end of a tube 42 as in the first embodiment. The tube 42 passes through the inside of the support rod 110 through the opening 92 a and extends to the gas cylinder 132, and the other end of the tube 42 is connected to the gas cylinder 132. By holding the injection unit 40 in a state where the injection port 40 a faces the heat generation unit 20, the combustible gas injected from the injection port 40 a is easily supplied into the heat generation unit 20.

FIG. 7 is a side view showing a state in a case where an operation test of the smoke detector 200 of the main body 100 according to the third example of the present embodiment is performed.

When the wire 94 is not pulled in the direction of the operation unit 120 via the operation unit 120, the injection unit 40 rotates around the rotation shaft 48 along the guide grooves 30g and 30h by the reaction force of the leaf spring, The table 92 is held in a state inclined by approximately 45 degrees.

In the third embodiment, the example in which the injection direction of the injection unit 40 is switched between when the operation test of the heat sensor 210 is performed and when the operation test of the smoke sensor 200 is performed has been described. However, a moving mechanism that functions as an injection position switching unit that moves the injection unit 40 in parallel along the base 92 may be provided. In this case, the injection unit 40 injects the injection unit 40 when the operation test of the heat sensor 210 and the operation test of the smoke sensor 200 are performed by translating the injection unit 40 along the base 92 by the moving mechanism. The position is switched.

FIG. 8 is a side view of the main body 100 according to the fourth example of the present embodiment. In FIG. 8, the heat generation part 80 is shown by sectional drawing. The main body 100 according to the fourth embodiment differs from the configuration of the main body 100 according to the second embodiment in that the first injection unit 40-1 is provided on the bottom surface in the heat generation chamber 80 of the heat generation unit 20. . In the fourth embodiment, the heat generation unit 20 has an opening 21b on the downstream side in the injection direction. A flame extinguishing element 22b having a mesh structure or a corrugated plate structure is attached to the opening 21b via an attachment ring 24b so as to cover the opening 21b. Furthermore, a platinum net 26 is attached as a catalyst to the surface of the flame extinguishing element 22b on the first injection unit 40-1 side. Further, an ejector 41 may be formed in the first branch gas pipe 44-1 in order to increase the pressure of the fuel gas. An ejector that boosts the fuel gas may be provided in the second injection unit 40-2. Further, an ejector may be provided in the first and second injection units 40-1 and 40-2 in the second embodiment.

As described above, according to the test device 10 according to the present embodiment, the test device for the heat detector and the test device for the smoke detector using the combustible gas that liquefies the water vapor by evaporative cooling are used. Therefore, the worker does not have to carry the heat detector for the heat detector and the smoke detector for the smoke detector, respectively, and the labor of the worker in the operation test of the heat detector and the smoke detector can be reduced.

Further, according to the test device 10 according to the present embodiment, it becomes easy to spray the combustible gas directly on the labyrinth of the smoke detector 200, so that the operation of the smoke detector 200 is facilitated. That is, since the time required for the operation of the smoke detector 200 is shortened, the supply time of the combustible gas from the gas cylinder 132 is also shortened. Therefore, the consumption of combustible gas can be suppressed.

Further, by combusting the combustible gas directly on the labyrinth of the smoke detector 200, the operation test of the smoke detector 200 can be performed without providing the case 60 as in the second, third, and fourth embodiments. It can be carried out.

In addition, the smoke detector may be activated again due to fog remaining after the smoke detector test. On the other hand, according to the test device 10 according to the present embodiment, after the smoke detector 200 is tested, heat is generated by the heat generation unit 20 so that the fog remaining after the test of the smoke detector 200 disappears in a short time. Therefore, it is possible to prevent the smoke detector 200 from operating again after the test. Conventionally, it may take time until the activated heat sensor stops due to overheating of the heat sensor. On the other hand, for example, in the tester 10 according to the second embodiment, after the test of the heat sensor 210, the combustible gas is injected from the second injection unit 40-2 toward the heat sensor 210, and the combustible gas is cooled. The heat sensor 210 may be cooled using the effect. By cooling the heat detector using the cooling effect of the combustible gas in this way, it can be prevented that it takes time until the heat detector once activated stops due to overheating of the heat detector. .

In addition, in the above, the heat generation part 20 demonstrated the example which generate | occur | produces heat with the reaction heat | fever of combustible gas by the catalytic action of the platinum net 26. However, the heat generation unit 20 may generate heat by burning the combustible gas in the heat generation chamber 80.

Further, an adjustment valve for adjusting the flow rate of the combustible gas output from the gas cylinder 132 may be provided in the operation unit 120. By providing the regulating valve, the flow rate can be optimized depending on the type of sensor or the difference in ambient temperature, so that work efficiency can be improved.

Furthermore, the main body 100 may be configured to be detachable from the support rod 110 so that the main body 100 can be connected to the existing support rod 110. Accordingly, it is possible to perform an operation test of the heat detector and the smoke detector using the existing support rod 110.

In addition, the main body 100 may be provided with a hook. By providing the main body 100 with a hook, the operator switches on the emergency lighting apparatus installed on the ceiling, for example, by using the hook, so that the operation test of the emergency lighting apparatus is performed by the heat detector and the smoke detector. Can be performed in parallel with the operation test.

By the way, when performing an operation test of a smoke detector, there is a conventional case where pseudo smoke is generated by liquefying water vapor using the evaporative cooling action of Freon gas. However, it is known that the cooling capacity of Freon gas is about half that of propane gas. That is, it is known that the cooling capacity of propane gas is about twice that of Freon gas. Therefore, when performing the operation test of the smoke detector, the operation test of the smoke detector can be performed with a gas consumption about half that of the Freon gas by using propane gas instead of the Freon gas. Therefore, for example, by using propane gas, it is possible to use a gas cylinder having a smaller capacity than when using chlorofluorocarbon gas, and thus the tester 10 can be downsized. In addition, when using propane gas, use a gas cylinder with the same capacity as when using chlorofluorocarbon, and perform operation tests on a larger number of heat sensors and smoke detectors than when using chlorofluorocarbon. be able to. Furthermore, since propane gas has a lower so-called global warming index than chlorofluorocarbon, environmental load can be suppressed by using propane bus compared to the case of using chlorofluorocarbon.
