Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, a smoke test box (smoke test instrument) 1 </ b> C according to an embodiment of the present invention has a box-shaped casing 31 that forms a test tank, and smoke is generated in the casing 31. A body 2 and a smoke densitometer 30 are provided, and a smoke detector K to be tested is arranged to check how much smoke concentration the smoke detector K operates.

  The smoke test box 1C includes a smoke generating body 2, a connector 15, an airflow sensor 19, a container 20, a blower 10, and a control unit 21, a power supply unit 22, a power switch 23, and a drive switch 24 that constitute the operation unit 5. In addition, the smoke density in the housing 31 is measured using the smoke densitometer 30, and density setting means 32 is provided for setting the smoke density in the housing 31 based on the measurement result.

  The smoke generating body 2 is provided in the vicinity of the cylinder 6, the heater 7 disposed in the cylinder 6, and the heater 7, holds the water-soluble liquid that is vaporized by the heat of the heater 7, and the water-soluble liquid And a liquid supply unit 8 for supplying the liquid to the heater 7. The smoke generating body 2 is connected to an air blowing means 10 which blows air from one end side, atomizes the vaporized water-soluble liquid to form pseudo smoke, and discharges the pseudo smoke from the discharge port 9 on the other end side. ing.

  The cylindrical body 6 is formed in a cylindrical shape having a circular cross section with both ends opened, and a smoke discharge port 9 is formed on one end side. The cross-sectional shape, diameter, and longitudinal dimension of the cylindrical body 6 are not particularly limited.

  The heater 7 is formed in a coil shape having a diameter smaller than that of the cylindrical body 6 using a metal wire such as a nichrome wire or a platinum wire, and is arranged in the longitudinal direction with the cylindrical body 6 and the axis L being substantially coincident with each other. One end 7a of the heater 7 is connected to a terminal of a heater connector 15 fixed to the bottom of the cylindrical body 6, and the other end 7b is folded at the end (tip) of the coil and directed toward the heater connector 15. It extends in a straight line, and is connected to the other terminal of the connector 15 in the same manner as the one end 7a, and is electrically connected to the control unit 21 via the connector 15. The control unit 21 allows a predetermined current to flow through the heater 7 in accordance with ON / OFF of the power switch 23 and the drive switch 24, thereby heating / stopping the heater 7.

  On the inner side and the outer side of the coil-shaped heater 7, for example, a fiber-based incombustible filter such as glass fiber or a non-combustible filter made of foamed resin is disposed as the liquid supply unit 8. The filter of the liquid supply unit 8 has a large number of air holes formed therein so as to be able to vent in all directions on the surface thereof, and a water-soluble liquid serving as a smoke generating agent can be held in the air holes. It has become. The liquid supply unit 8 can be atomized by the heat of the heater 7 by supplying the smoke generating agent to the heater 7 along the heater 7 in a state of being impregnated with the water-soluble liquid, that is, in contact with or adjacent to the heater 7. It is installed as follows.

  As a component of the water-soluble liquid, a water-soluble liquid that is hydrophilic and has a high water retention property, such as a water-insoluble liquid that is harmless to the human body including at least one component such as glycerin and propylene glycol. The water-soluble liquid is preferably a component that has high moisture retention and is less likely to volatilize, and is preferably a component that does not alter the smoke detector K and the ceiling material W of the building (see FIG. 1).

  A container 20 having a heater connector 15 and an airflow sensor 19 therein is connected to the base end side (support bar 4 side) of the cylindrical body 6. The air blowing means 10 is connected to the container 20 through a hollow rod-like body so as to be able to vent. The air flow from the air blowing means 10 is blown into the cylindrical body 6 through the internal space of the container 20, and the heater 7 The vaporized water-soluble liquid is atomized to form pseudo smoke (aerosol) S and the generated pseudo smoke S is discharged from the discharge port 9. For example, a blower pump or a fan is used as the blower unit 10.

  The airflow sensor 19 is a device that detects the airflow in the container 20. When air is blown in by the blower 10, the airflow sensor 19 detects the airflow, sends a signal to the control unit 21, and sends a predetermined current to the heater 7. When the airflow is not detected, the current to the heater 7 is limited or cut off so as not to be heated. The air flow sensor 19 prevents the heater 7 from being heated even when there is no air flow, thereby causing the temperature to rise abnormally, and the heater 7 is heated with a predetermined current only when an air flow is detected. Yes. When the heater 7 is heated and reaches a predetermined temperature, the water-soluble liquid is vaporized. An appropriate sensor may be provided in addition to the airflow sensor 19, and the control unit 21 may further perform control such as temperature control of the heater 7 and prevention of overheating based on these signals. Further, the supply current value to the heater 7 may be changed continuously or stepwise according to the change or strength of the airflow, the change in temperature or the height of the heater 7, and the like.

The operation unit 5 includes a control unit 21 that controls heating / heating stop of the heater 7 according to the detection of the airflow by the airflow sensor 19, a power supply unit 22, and a power source that connects the control unit 21 and the power supply unit 22. A switch 23 and a drive switch 24 that supplies power to the blowing unit 10 via the control unit 21 and drives the blowing unit 10 while the power switch 23 is ON are provided.
The power supply unit 22 may be any device that can supply operating power. For example, a dry battery, a rechargeable battery, or an AC power supply can be used.

  As the smoke detector K, a smoke detector adopting a scattered light method as a detection principle is used.

  As described above, according to the smoking test box 1C, the smoke detector K and the ceiling material are generated in order to generate the pseudo smoke S obtained by atomizing the water-soluble liquid as smoke for operating the smoke detector K on a trial basis. It is possible to check the operation of the smoke detector K suitably by avoiding the sticking of viscous oily smoke or the like to the W to contaminate the sensor K or the like, or further attaching dust. In particular, water-soluble liquids contain components such as propylene glycol and glycerin that are hydrophilic and have high water retention properties. Therefore, these components evaporate with water using a heater, and these components become the core at the jet nozzle. And atomize. Since these components have high water retention, unlike the case where only water evaporates, they can float well in the air for a while and play a role as simulated smoke. This has been confirmed by experiments conducted by the inventors. In general, it is believed that propylene glycol or glycerin evaporates with water and then atomizes and discharges, then cools to become nuclei, and water vapor aggregates to form white smoke. And since propylene glycol and glycerin have high hydrophilicity and take in the evaporated water and prevent the evaporation of the taken-in water, the white smoke will float in the air for a relatively long time.

On the other hand, since the smoke using the water-soluble liquid evaporates in the environment soon after the test, it can be avoided that the smoke remains attached to the smoke sensor K and affects its sensitivity.
Moreover, since the smoke generating body 2 can be manufactured with a simple structure using a water-soluble liquid of an inexpensive component and an inexpensive resin member, the manufacturing cost of the smoke test box 1C can be suppressed. In addition, since environmentally harmful gases such as chlorofluorocarbon are not discharged, the environmental load is small.

Furthermore, since the water-soluble liquid is vaporized and then atomized to generate pseudo smoke and discharged by the air blowing means 10, the smoke concentration and emission amount can be easily controlled, and smoke detection is performed accurately and efficiently. The operation of the device K can be confirmed.
In addition, odorless components, low odor components, or odor-friendly components can be selectively used as water-soluble liquids, and the smoke test box 1C is used in hospitals and other places where many people gather. The effect is easy. Alternatively, when an odor that does not cause discomfort to humans is added to the water-soluble liquid, the smoke remaining state can be recognized after the operation test of the smoke detector K by the smoke test box 1C.

  In addition, a coil-shaped heater 7 is disposed along the axis L of the cylindrical body 6, and a liquid supply unit 8 impregnated with a water-soluble liquid is disposed inside and outside the coil of the heater 7. The effect that the water-soluble liquid of the part 8 can be efficiently vaporized in a wide range by the coil heater 7 is obtained. In addition, the heater 7 can adjust the generation | occurrence | production density | concentration of the pseudo smoke S suitably by narrowing or expanding the winding pitch of a coil, and adjusting the internal diameter of a coil.

  As described above, the embodiment of the present invention has been described using the smoke test box 1C. However, the present invention is not limited to the embodiment shown in the above-described embodiment, and does not depart from the spirit of the present invention. Thus, each part can be appropriately changed and used in a more preferred embodiment.

Specifically, the cylinder 6 including the heater 7 and the liquid supply unit 8 impregnated with the water-soluble liquid is configured to be detachable from the cover 11 and the container 20 by, for example, a screwing structure or a fitting structure. can do.
By adopting such a configuration, even when the water-soluble liquid or the heater 7 is consumed, the liquid supply unit 8 and the heater 7 can be easily replaced together with the cylindrical body 6, and the smoke test box 1C can be economically operated. The effect that it can be used is obtained.

  Further, the liquid supply unit 8 impregnated with the water-soluble liquid may be configured to be detachable from the cylindrical body 6. Moreover, the heater 7 of the smoke generating body 2 shown in said embodiment may be replaceable. By making the liquid supply part 8 and / or the heater 7 impregnated with a water-soluble liquid detachable, the effect that the most consumable part of the smoke test box 1C can be efficiently exchanged can be obtained. .

  In addition to the air blowing means 10 for blowing air into the cylinder 6 of the smoke generating body 2, the fan 35, the fan 35 switch 36 and the fan are provided in the vicinity of the smoke generating body 2 or in the operation unit 5 as illustrated in FIG. By providing 35 transmissions (not shown), it is possible to adopt a configuration that can accelerate the emission of the pseudo smoke S as necessary. By providing such a fan 35, it becomes possible to quickly fill the entire interior of the casing 31 with the pseudo smoke S emitted from the emission port 9 of the smoke generating body 2 without staying in the vicinity of the emission port 9. The effect is obtained.

Furthermore, in addition to the above-described configuration, a changeover switch that switches energization or interruption (ON / OFF) of current to the heater 7 may be provided.
By making the air blowing means 10 or the fan 35 usable so that the heater 7 can be turned on and off, the heater 7 is energized (turned on) when performing an operation test of the smoke detector K. While generating the pseudo smoke S, as described above, the pseudo smoke S can be quickly filled by the blowing means 10 or the fan 35. When the operation test is completed, the energization of the heater 7 is cut off (turned off) to stop the generation of the pseudo smoke S, and the blowing means 10 or the fan 35 is driven in this state to detect smoke. The air can be sent toward the device K, and the released smoke S can be quickly removed from the smoke detector K and its surroundings. As a result, after the operation test of the smoke detector K is completed, the normal smoke detection state can be promptly restored.
Note that a cylinder filled with compressed air may be used instead of the blower 10 or the fan 35.
Further, the blower 10 or the fan 35 may be provided with a changeover switch (not shown) that reversely rotates the fan. By providing such a change-over switch and rotating the fan in the reverse direction, the smoke emitted after the operation test is completed can be sucked and the smoke around the smoke sensor K can be quickly removed.

  Further, the liquid supply unit 8 impregnated with the water-soluble liquid is disposed only on the inner peripheral side of the coil shape of the heater 7, and a sponge filter that forms an air flow path without impregnating the water-soluble liquid on the outer side thereof. May be arranged. Further, the outer sponge filter does not necessarily have to be arranged as long as the heater 7 and the liquid supply unit 8 can be positioned and fixed in the cylinder 6 and an appropriate amount of air can flow. Further, the liquid supply unit 8 impregnated with the water-soluble liquid may be disposed only outside the coiled heater 7.

Further, in the above embodiment, the heater 7 is formed in a coil shape. However, as shown in FIG. 3, the metal wire arranged on a straight line is moved from the proximal end 6 a side to the distal end 6 b side of the cylindrical body 6. Even if both ends of the metal wire are connected to the respective terminals of the heater connector 15 so as to extend linearly toward the end, bend in the vicinity of the distal end 6b and extend linearly toward the base end 6a. Good.
Further, as shown in FIG. 4, the heater 7 is formed by bending a metal wire into a comb shape on one plane, and the heater 7 formed on a flat plate is formed by two flat plate filters (liquid supply portions) 8 (FIG. 4). 4, the heater 7 may be placed in contact with or in close proximity to the liquid supply unit 8 by sandwiching the flat plate filter on one side (the back side of the drawing).

  5-7 is the figure which looked at the smoke generating body 2 in the cross section in the surface containing the axis line L and the heater 7. FIG. As shown in these drawings, the heater 7 does not necessarily need to be a metal wire, and may be a rod-like body or a plate-like body made of ceramic or metal. In this case, the rod-like or plate-like heater 7 made of ceramic or metal has one rod-like or plate-like heater 7 arranged in the cylinder 6 as shown in FIG. In addition, a liquid supply unit 8 impregnated with a water-soluble liquid may be disposed so as to cover the surfaces 7a, 7b, etc. of the rod-like or plate-like heater 7, or as shown in FIG. A plurality of rod-like other or plate-like heaters 7, 7... Are arranged at intervals, and ventilation is possible between these heaters 7, 7 .. and between the heater 7 and the cylindrical body 6. Alternatively, a liquid supply unit 8 impregnated with a water-soluble liquid may be disposed. Also in this case, substantially the same effect as the above embodiment can be obtained.

  The surfaces 7a, 7b, etc. of the metal or ceramic rod-like or plate-like heater 7 shown in FIGS. 5A and 5B are the same as the heater 7 shown in FIG. May be formed in a wave shape. With such a configuration, the contact area between the heater 7 and the sponge fill 8 impregnated with the water-soluble liquid can be further increased, and smoke can be generated efficiently.

Further, as shown in FIG. 7, the smoke generating body 2 may be externally provided with a liquid holding container 40 for storing a water-soluble liquid and supplying the liquid supply unit 8 with a small amount of the smoke generating agent.
In this case, since the liquid holding container 40 supplies the water-soluble liquid stored with respect to the liquid supply part 8, it has the fine hole 41 which only allows air to flow in from the outside, and water-soluble liquid is supplied to the opening. What connected the pipe | tube 43 made to flow is used. The tube 43 is connected to the liquid supply unit 8. The shape of the container body 44 may be a rectangular parallelepiped shape, a cylindrical shape, or any other shape.
