Description

  The present invention relates to a sensitivity test apparatus used for a sensitivity test of a smoke detector.

  Conventionally, fire alarms have been installed in buildings such as offices. When a fire breaks out, the smoke generated by the fire is detected by a smoke detector and an alarm signal is sent to the receiver to give a fire alarm. It is output so that it can perform fire fighting, evacuation and fire fighting activities.

  The fire alarm system is regularly inspected after installation in the building. For the smoke detector, remove the smoke detector installed on the ceiling and use the sensitivity test device that was brought in during the inspection. The sensitivity test of the smoke detector is conducted.

  In the sensitivity test device, a smoke detector to be tested is placed in the test space inside the device housing, and in this state, smoke is supplied from the smoke generator to the test space, and the smoke detector reports at a predetermined smoke concentration. A sensitivity test is conducted to confirm this.

  Incense sticks and filter paper are used as smoke bodies used in the sensitivity test apparatus. However, when using incense sticks, the smell is so strong that it is discouraged from being used in buildings where many people gather, especially in hospitals, and the number of items that can be inspected with a single incense stick is limited. In addition, since incense smoke has a relatively small particle size, ionization smoke detectors are easy to report in a short time, but in the case of photoelectric smoke detectors, it takes time to report. There was a problem that the work efficiency of inspection was poor.

  In addition, when filter paper is used as the smoke emitting body, for example, filter paper chopped to about 1 cm square is fired with a pot heater, so it is difficult to continuously generate smoke at a constant speed. Since the heater is constantly heated to about 400 ° C., there is a problem that power consumption increases.

  In order to solve such a problem, in the sensitivity test apparatus disclosed in Patent Document 1, a smoke generator that emits smoke from the tip is provided in the test space of the sensitivity test apparatus. A liquid supply unit impregnated with a functional liquid, and when performing a test, smoke is sent by sending air from the blower unit into the cylinder, atomizing the water-soluble liquid vaporized by heating with a heater, and emitting pseudo smoke The sensitivity test is performed.

  According to such a smoke test jig, it generates pseudo smoke that is atomized by vaporization of a water-soluble liquid, so there is no problem of odor and the like, and smoke is generated continuously at a constant speed. Therefore, the sensitivity test of the smoke detector can be advanced efficiently at the inspection site.

Etc. need to be additionally provided to the sensitivity test apparatus, the configuration of the sensitivity test apparatus becomes complicated, and there is a problem that the existing sensitivity test apparatus cannot be fully utilized.

  In addition, when a smoke generating body that generates pseudo smoke atomized by vaporization of a water-soluble liquid is incorporated in the sensitivity test device, a structure for enabling replacement of the used smoke generating body is required. In some cases, it is desirable to fully utilize the structure of the existing sensitivity test apparatus.

(Overview of the smoke generator)
As shown in FIG. 3, a smoke generating part 32 is incorporated in the main body 12 of the smoke generating device 10. The smoke generation unit 32 includes a power supply unit 38, a holder 34, a smoke generation cartridge 36, an air pump unit 40, an air hose 42, a blower unit 44, an airflow detection unit 46 and a control unit 48.

  A mounting hole 15 is formed on the distal end side of the main body 12, and a connecting pipe 14 is detachably fitted into the mounting hole 15. A storage portion 16 is formed following the attachment hole 15. A holder 34 is fitted into the inside of the connecting pipe 14 fitted into the mounting hole 15 from the storage portion 16.

  As shown in FIG. 4, the holder 34 has a hollow cylindrical member opened at the lower end thereof, an overhang portion 35 formed on the outer periphery, a cartridge attachment portion 50 provided at the upper end, and a smoke generating cartridge in the attachment hole of the cartridge attachment portion 50. 36 is detachably mounted. A plug 52 is formed on the outer periphery of the lower side of the smoke generating cartridge 36. When the smoke generating cartridge 36 is inserted into the cartridge mounting portion 50, the connection pin of the plug 52 is connected to the connector 54 on the holder 34 side. I am doing so.

  The holder 34 is a hollow cylindrical member. However, since the smoke generating cartridge 36 only needs to be held on the opening side of the mounting hole 15, it does not need to be so strong. For example, the hollow cylindrical member having a mesh structure has flexibility. You may make it.

  A hose connection port 56 is provided under the cartridge mounting portion 50, and the air hose 42 from the air pump portion 40 of FIG. 3 is connected through the holder 34 and sent out from the air pump portion 40 as indicated by an arrow A. The pressurized air is fed into the smoke cartridge 36.

  An opening 55 is formed around the cartridge mounting portion 50 provided at the upper end of the holder 34, and as shown by an arrow B, the air flow sent from the air blowing portion 44 of FIG. Through the opening 55 and through the periphery of the smoke generating cartridge 36 to the connection pipe 14 side.

  Referring to FIG. 3 again, the power supply unit 38 is provided with a rechargeable secondary battery such as a lithium ion battery. The smoke generating cartridge 36 provided in the smoke generating unit 32, the air pump unit 40, the air blowing unit 44, the air flow Power is supplied to the detection unit 46 and the control unit 48. The power supply unit 38 may be a primary battery that cannot be recharged or an AC-DC conversion adapter that inputs a commercial AC power supply from the sensitivity test apparatus 100 shown in FIGS. 1 and 2 and outputs a predetermined DC voltage.

  The air pump unit 40 outputs pressurized air by electromagnetic drive. For example, an air pump for a water tank or the like is used, and the air hose 42 sends pressurized air to the smoke generating cartridge 36 attached to the tip of the holder 34. ing.

  An adapter 45 in which an airflow detection unit 46 is housed is provided in the middle of the air hose 42 that connects the air pump unit 40 and the smoke generating cartridge 36, and an airflow flowing through the air hose 42 is detected to detect an airflow detection signal. Is output to the control unit 48. The airflow detection unit 46 is not limited to the middle of the air hose 42 as long as it is a route for sending pressurized air from the air pump unit 40 to the smoke generation cartridge 36, and may be provided at an appropriate position including the inside of the smoke generation cartridge 36. good.

  The air blower 44 is a motor-driven fan that passes pseudo smoke emitted from the smoke cartridge 36 into the sensor cover 16 through the holder 34, around the smoke cartridge 36, and further through the internal passage of the support rod 14. I try to send it in.

  When the power switch 20 is turned on, the control unit 48 receives power supply from the power supply unit 38 and enters an operating state. When the control unit 48 detects the on operation of the operation switch 18, the control unit 48 drives the air pump unit 40 to supply the compressed air to the air. The air is sent to the smoke generating cartridge 36 through the hose 42, and the fan is rotated by driving the motor of the blower unit 44, whereby the air is sent from the holder 34 through the periphery of the smoke generating cartridge 36.

  In addition, the control unit 48 switches and selects the amount of air blown by the air blowing unit 44 based on the selection of the two levels of strength or the selection of air blowing and sending stop by operating the air blowing changeover switch 21. When the sensitivity test device 100 is used to select both of the air blows by the air blow switch 21, since the circulation fan 106 is provided in the sensitivity test device 100, the air flow rate is reduced or stopped, and the air pump unit 40. Utilize smoke inflow by pressurized air from On the other hand, as will be clarified in the description of FIG. 9 later, when used in a smoke test apparatus, the blowing amount is set to strong or blown, and the smoke generated is blown from the blower portion 44 via the support rod. Into the sensor cover at the tip.

  In addition, when the control unit 48 detects the airflow flowing by driving the air pump unit 40 based on the airflow detection signal of the airflow detection unit 46 provided in the air hose 42, the control unit 48 energizes the heater built in the smoke generating cartridge 36. And controlling the generation of simulated smoke by evaporating the aqueous solution for fuming impregnated in the liquid supply unit incorporated in the fuming cartridge 36.

(Smoke cartridge)
As shown in FIG. 5, in the smoke generating cartridge 36, a rod-shaped liquid supply unit 66 is accommodated in a cylindrical body 60, a heater 68 is wound around the liquid supply unit 66, and the tip of the heater 68 is connected to the plug 52. Connected to pin 53.

  The cylindrical body 60 has an inlet 62 at the lower end, and introduces the pressurized air sent from the air pump unit 40 of FIG. 3 into the cylindrical body 60 as indicated by an arrow A. In addition, a discharge port 64 is opened at the top of the cylindrical body 60, and air introduced from the inflow port 62 is discharged upward.

  The liquid supply unit 66 is formed by forming a fiber-based non-combustible filter such as glass fiber or a non-combustible filter made of foamed resin into a rod shape, and the filter has a large number of voids that are open to allow ventilation in all directions on the surface. A hole is formed inside, and a predetermined water-soluble liquid serving as a smoke generating agent is impregnated in the void hole.

  A heater 68 using a metal wire such as a nichrome wire or a platinum wire is spirally wound around the liquid supply unit 66, and the water-soluble liquid impregnated in the liquid supply unit 66 is brought into contact with the heater 68. The water-soluble liquid impregnated in the liquid supply unit 66 is vaporized by heating when energized, and is put on an air current and discharged from the discharge port 64 to generate atomized pseudo smoke (aerosol).

  As the water-soluble liquid to be impregnated in the liquid supply unit 66, a water-soluble liquid that is hydrophilic and has a high water retention property, for example, a water-insoluble liquid that is harmless to the human body including at least one component such as glycerin and propylene glycol. It has been.

  When a water-soluble liquid containing components such as glycerin and propylene glycol impregnated in the liquid supply unit 66 is heated by the heater 68 and vaporized, the components such as glycerin and propylene glycol are evaporated together with water and emitted from the discharge port 64. After that, it cools and becomes a nucleus, and water vapor condenses on this to form white smoke, so that pseudo smoke is generated.

  In the pseudo smoke generated in this way, white smoke is relatively long because propylene glycol and glycerin are highly hydrophilic and take up evaporated water and prevent evaporation of the taken-in water. It will float in the air over time.

(Cartridge replacement lid)
As shown in FIG. 6, a cartridge replacement lid 19 is detachably provided on the operation portion 12, and is formed on the peripheral side surface of the connecting pipe 14 when the cartridge replacement lid 19 is removed from the operation portion 12 as shown in the figure. The smoke cartridge 36 attached to the tip of the holder 34 is exposed inside the opened opening 23, the smoke cartridge 36 that has been used up is removed, replaced with a new smoke cartridge, and the cartridge replacement lid 19 is closed.

  The smoke cartridge 36 can be replaced with the connecting pipe 14 attached. However, if the opening 23 is not formed in the support rod 22, the cartridge replacement lid 19 is opened with the connecting pipe 14 removed from the operation unit 12. The smoke cartridge 36 can be replaced. The cartridge replacement lid 19 may have a door structure that can be freely opened and closed.

[Test work with sensitivity test equipment]
Next, the sensitivity test of the smoke detector by the sensitivity test apparatus 100 using the smoke generator 10 will be described.

  As shown in FIGS. 1 and 2, when the sensitivity test of the smoke detector is performed by the sensitivity test apparatus 100, the sensor mounting door 104 is opened as shown in the sensor mounting lid 104a of FIG. The smoke detector 30 is attached to the inner mounting base 105 and closed. In this state, the connection pipe 14 of the smoke generator 10 shown in FIG. 3 is inserted into the smoke inlet 120, and the power switch 20 of the smoke generator 10 is inserted. 3 is turned on, the control unit 48 shown in FIG. 3 detects that the operation switch 18 is turned on, drives the air pump unit 40, and the smoke generating cartridge 36 via the air hose 42. Since the pressurized air is fed into the air flow switch 21 and the air volume changeover switch 21 is switched to a weak level, the air blower 44 is driven to drive the inside of the holder 34, the smoke cartridge 36, and the inside of the connecting pipe 14. Feeding the wind with a weak air flow in the sensor cover 16 through the passage. In addition, when the air blowing selection switch 21 is switched to the air blowing stop, the air blowing unit 44 is not driven.

  The signal level of the airflow detection signal is increased from the airflow detection unit 46 provided in the middle of the air hose 42 by the air blow from the air pump unit 40, and the control unit 48 causes the smoke generating cartridge 36 when the airflow detection signal exceeds a predetermined threshold level. The heater 68 provided in is energized and heated. Thus, since the heater 68 is not energized unless the airflow to the smoke generating cartridge 36 increases, abnormal heating due to energization of the heater 68 when there is no airflow or when the airflow is low can be prevented.

  When the liquid supply unit 66 is heated by energization of the heater 68, the water-soluble liquid containing components such as glycerin and propylene glycol impregnated in the liquid supply unit 66 is vaporized, and the pressurized air from the air pump unit 40 is used. By being discharged from the discharge port 64, it is atomized and pseudo smoke is generated.

  The simulated smoke emitted from the smoke generation cartridge 36 passes through the inner passage of the connection pipe 14 by the air flow sent from the blower 44 through the holder 34, and the inside of the sensitivity test apparatus 100 shown in FIG. It is discharged to the lower right corner of the test space 101 and is sent to the upper space of the test space 101 through the current plate 108 by the circulation fan 106 to increase the smoke density.

  For this reason, when pseudo smoke flows into the smoke detector 30 and the smoke detector 30 is triggered and the alarm indicator lamp 132 is lit, the sensitivity is determined by whether or not the display of the densitometer 136 is within a predetermined range. Check.

  Here, the smoke generating cartridge 36 of the smoke generating apparatus 10 has a constant amount of pseudo air by making the amount of pressurized air sent from the air pump unit 40 constant with respect to the cylindrical body 60 provided with the heater 68 and the liquid supply unit 66. Smoke can be stably generated and emitted, and the pseudo smoke released from the smoke cartridge 36 is sent to the test space 101 of the sensitivity test apparatus 100 by the air blowing unit 44 provided separately, and stable pseudo smoke is generated. It is possible to achieve both the generation and the sending of pseudo smoke corresponding to the test space 101, and it is possible to increase the smoke density in the test space 101 without time delay and to efficiently perform the sensitivity test of the smoke detector 30.

[Embodiment of sensitivity test apparatus with built-in smoke generation unit]
FIG. 10 is an explanatory diagram showing an embodiment of a sensitivity test apparatus with a built-in smoke generating unit, and FIG. 11 is an explanatory diagram showing the sensitivity test apparatus of FIG. 10 from the side.

  As shown in FIGS. 10 and 11, in this embodiment, a cartridge storage unit 200 that functions as a cylindrical storage unit having a drawer structure is provided at the lower right front of the housing 102 of the sensitivity test apparatus 100, for example. The cartridge storage unit 200 is formed in a box shape that opens upward. The cartridge storage unit 200 utilizes a smoke box structure that can be pulled out using an existing incense stick.

  A smoke generating cartridge 36 is detachably stored in the cartridge storage unit 200 with the same structure as shown in FIG. As shown in FIG. 5, the smoke cartridge 36 is provided with a liquid supply unit 66 and a heater 68 in a cylindrical body 60. In addition, a smoke outflow pipe 202 is arranged from the depth surface of the cartridge storage unit 200 so that smoke sent out from the smoke generating cartridge 36 is sent into the test space 101.

  The air hose 42 has play by being bent in the middle, and can be pulled out from the front surface of the housing 102 as shown in an imaginary line cartridge housing portion 200a. An airflow detector 46 is provided in the middle of the air hose 42. Along with the air hose 42, a signal line (not shown) for the heater provided in the smoke generating cartridge 36 is also drawn.

  The power source for the smoke generating cartridge 36, the air pump unit 40, the air blowing unit 44, the airflow detecting unit 46, and the control unit for the smoke generating unit uses the power source from the sensitivity test apparatus 100. The control unit of the smoke generation unit is mounted on the same circuit board as the sensitivity test apparatus 100.

  For example, when the power switch 122 is turned on, the control unit of the smoke generation unit receives an electric power supply to be in an operating state, drives the air pump unit 40, and sends compressed air to the smoke generation cartridge 36 via the air hose 42. Control is performed to send the smoke from 36 to the suction side of the circulation fan 106 via the smoke outflow pipe 202. Note that a separate smoke control switch may be provided, and the air pump unit 40 may be driven when the smoke control switch is turned on with the power switch 122 turned on.

  In addition, the control unit of the smoke generation unit detects the airflow flowing by driving the air pump unit 40 based on the airflow detection signal of the airflow detection unit 46 provided in the air hose 42, and the heater built in the smoke generation cartridge 36 is used. Control is performed to emit pseudo smoke by energizing and heating and evaporating the aqueous solution for fuming impregnated in the liquid supply unit incorporated in the fuming cartridge 36.

  When the smoke generating cartridge 36 is used, as shown in the cartridge storing portion 200a, when the cartridge storing portion 200 is pulled out from the housing 102, the upper peripheral surface of the smoke generating cartridge 36 is exposed in the cartridge storing portion 200.

A cable 308 is drawn into the body 102.

  In addition, a non-combustible cotton member 310 such as glass fiber that functions as a liquid supply unit in contact with or in proximity to the heater 306 is disposed. When using the smoke generating device 10, a spoid or the like is used. For example, the cotton member 310 is impregnated with a water-soluble liquid containing at least one of components such as glycerin and propylene glycol, which becomes a smoke generating agent.

  As the power source for the heater 306 of the smoke container 302, the power source from the sensitivity test apparatus 100 is used. The control unit of the smoke generation unit is mounted on the same circuit board as the sensitivity test apparatus 100.

  For example, when the power switch 122 is turned on, the control unit of the smoke generating unit is activated by receiving power supply, and vaporizes the water-soluble liquid impregnated in the cotton member 310 by energizing and heating the heater 306. Thus, pseudo smoke is generated and sent to the suction side of the circulation fan 106.

  When the water-soluble liquid is used up, the smoke container storage unit 300 may be pulled out and the cotton member 310 in the smoke container 302 may be supplemented and impregnated with a syringe using a dropper or the like.

  As another form, a storage unit for storing a water-soluble liquid may be provided, and one end side of the cotton member 310 may be inserted to a predetermined depth in the storage unit, and the heater 306 may be wound around the other end side. . Since one end of the cotton member 310 is immersed in a water-soluble liquid, the water-soluble liquid is impregnated in the entire cotton member 310 by a capillary phenomenon, and pseudo smoke can be generated by heating with a heater.

  Since the water-soluble liquid can be stored in the storage unit, it is possible to reduce the trouble of replenishing the water-soluble liquid. Further, by impregnating the cotton member 310 with the water-soluble liquid, there is no possibility that the water-soluble liquid is supplied to the heater at a time, so that the amount of smoke can be appropriately managed.

  Thus, in the sensitivity test apparatus 100 of this embodiment, since the structure of the smoke generator 10 is simple, it can be realized at a low cost, and it is easy to replenish an aqueous solution as a smoke generator. Excellent handling.

  In the above-described embodiment, the cotton member 310 is disposed in contact with or close to the heater 306. However, as another embodiment, the cotton member 310 is formed in a cylindrical body, and the cotton member 310 is formed in the cylindrical body. Alternatively, the heater 306 may be wound around the outside. Further, the cotton member 310 may be formed in a cylindrical body, and the heater 306 may be disposed in the cylindrical hole of the cotton member 310 formed in the cylindrical body.
