[Embodiment 1]
FIG. 1 is a schematic diagram showing a smoke tester 1 according to the first embodiment.
In FIG. 1, the external appearance of the smoke tester 1 in Embodiment 1 is detachably attached to a cylindrical first casing 5 having a partition plate 3 on the lower side and a lower portion of the first casing 5, for example. A bottomed cylindrical second casing 7 and a silicon cover 9 which is detachably attached to the upper portion of the first casing 5 and can be expanded and contracted in the axial direction. Two shafts (not shown) facing each other are attached to the outer peripheral surface of the first casing 5. Although not shown, the two shafts are rotatably attached to a U-shaped support that is fixed to the tip of the support bar. Thereby, the smoke tester 1 itself can be freely tilted with respect to the support rod.
The above-mentioned support rod has a predetermined length, the smoke tester 1 is provided at one end via the support, the operator holds the other end, and the smoke detector SD attached to the ceiling C is added. Take the smoke tester 1 with you. Thereafter, the operator presses the smoke tester 1 against the ceiling C, turns on an operation switch 29 described later, and holds it until the smoke generating agent 31 is atomized and the smoke detector SD is activated.

  The partition plate 3 of the first casing 5 is provided with a tank part 13 having an insertion port 11 in the upper center and an atomizing part casing 15 that covers the tank part 13. Further, the partition plate 3 of the first casing 5 is provided with a plurality of air inlets 17 in the circumferential direction between the atomizing section casing 15 and the tank section 13. Further, in the partition plate 3 of the first casing 5, a plurality of air inlets 19 are provided between the first casing 5 and the atomizing portion casing 15 in a concentric circumferential direction outside the air inlet 17. A ring-shaped smoke circulation path 21 (circulation means) is formed between the first casing 5 and the atomizing section casing 15 as viewed from above. On the lower surface of the partition plate 3 of the first casing 5, for example, a blower fan 23 of a blower unit using a DC motor as a drive source is attached.

  Above the atomizing section casing 15, a nozzle 25 for emitting smoke S toward the smoke detector SD and an operation switch 29 such as a micro switch connected to the circuit board 27 are provided. A smoke generating agent 31 is stored in the tank unit 13. The smoke generating agent 31 is made of water or a mixture containing at least water and having a small global warming potential. For example, the smoke generator 31 is a mixture of glycerin and propylene glycol containing water. The smoke generating agent 31 has a smaller global warming potential than that containing Freon gas, which has been frequently used in the conventional smoke tester 1.

The tank part 13 is provided with an atomizing part 33 for heating and atomizing the smoke generating agent 31 accommodated in the tank part 13. The atomization part 33 is demonstrated in detail below based on FIG.
FIG. 2 illustrates an upright section in a state where the atomizing section 33 is installed in the tank section 13.

As shown in FIG. 2, the atomizing section 33 has a narrow tube 35 as a smoke generating agent pulling member that is immersed in the smoke generating agent 31 housed in the tank portion 13 at one end and pulls the smoke generating agent 31 to the other end. The first coil heater 37a serving as the first heating means for heating the smoke generating agent 31 provided on the other end side of the heater and the second coil heater 37b serving as the second heating means. The 1st coil heater 37a and the 2nd coil heater 37b are wound and attached to the 1st cylinder 39a and the 2nd cylinder 39b made from a ceramic installed in the upper part of thin tube 35.
In addition, the insertion port 11 is provided in the upper center of the tank part 13, and the rubber stopper 41 is installed in the insertion port 11 so that the smoke generating agent 31 does not spill out. And the thin tube 35 is inserted and installed in the through-hole provided in the rubber stopper 41, and is maintaining the stable standing state.

<Narrow tube>
The thin tube 35 is one aspect of the smoke generating material pulling member of the present invention, and the material thereof is not particularly limited, but examples thereof include a glass tube. The inner diameter of the thin tube 35 is set to a very small diameter so that the smoke generating agent 31 stored in the tank portion 13 can be pulled up by capillary action.
The lower end portion of the narrow tube 35 is inserted into the smoke generating agent 31 stored in the tank unit 13 at all times, and the smoke generating agent 31 is always pulled up to the upper end portion of the narrow tube 35.

<First coil heater and second coil heater>
The first coil heater 37a is an aspect of the first heating means of the present invention, and the second coil heater 37b is an aspect of the second heating means of the present invention.
The first coil heater 37a is provided on the outer peripheral portion on the upper end side of the thin tube 35, and the second coil heater 37b is provided on the outer peripheral portion of the thin tube 35 at a predetermined distance below the first coil heater 37a. Yes. The distance between the first coil heater 37a and the second coil heater 37b is that the smoke generating agent in the meantime emits smoke in one test, so that the amount of the smoke generating agent required for at least one smoke generation in the thin tube 35 during this period. The distance to be accommodated. However, this distance is not strictly defined, and any distance may be used as long as the amount of smoke generating agent necessary for one test is released.

The 1st coil heater 37a heats the upper end part of the thin tube 35, and is for atomizing the smoke generating agent 31 pulled up by the upper end part of the thin tube 35. As shown in FIG.
The 2nd coil heater 37b is for heating the intermediate part of the thin tube 35, atomizing the smoke generating agent 31 pulled up in the thin tube 35, and generating a bubble by atomization.
Details of the operation of the first coil heater 37a and the second coil heater 37b will be described later.

  Although the 1st coil heater 37a and the 2nd coil heater 37b are formed, for example with a nichrome wire, the material is not specifically limited.

In the present embodiment, the first coil heater 37a and the second coil heater 37b are wound around a first cylinder body 39a and a second cylinder body 39b made of ceramic.
The smoke generating agent 31 is in the glass thin tube 35, and the first coil heater 37a and the second coil heater 37b are wound around the first tube body 39a and the second tube body 39b made of ceramic disposed on the outer periphery of the thin tube 35. Since it is rotated, the first coil heater 37 a and the second coil heater 37 b do not contact the smoke generating agent 31.
The reason why the first coil heater 37a and the second coil heater 37b are not brought into contact with the smoke generating agent 31 is as follows.
When the smoke generating agent 31 is heated and atomized, impurities such as tar contained in the smoke generating agent 31 become a residue. If the residue adheres to the first coil heater 37a and the second coil heater 37b, the first coil heater 37a and the second coil heater 37b deteriorate, and the atomizing agent 31 cannot be atomized continuously and stably.

In the present embodiment, since the smoke generating agent pulling member is constituted by the glass thin tube 35, the smoke generating agent 31 is used as the first coil heater 37a and the first coil heater 37a without the first cylindrical body 39a and the second cylindrical body 39b. Since the two-coil heater 37b is not touched, the first coil heater 37a and the second coil heater 37b may be wound directly around the thin tube 35.
However, by winding the first coil heater 37a and the second coil heater 37b around the first cylinder 39a and the second cylinder 39b, the thin tube 35, the first cylinder 39a and the second cylinder 39b can be inserted and removed. The effect that the replacement work when the thin tube 35 is soiled with the residue becomes easy is obtained.
Further, the first cylindrical body 39a and the second cylindrical body 39b also function as a reinforcing material that prevents breakage such as breaking of the thin tube 35.

The effect | action of the atomization part 33 is demonstrated below based on FIG.
FIG. 3A shows a state in which the operation switch 29 is off. At this time, the smoke generating agent 31 is pulled up to the upper end in the capillary 35 by a capillary phenomenon. When the operation switch 29 is turned on in this state, heating of the first coil heater 37a and the second coil heater 37b is started (see FIG. 3B). Then, the atomization of the smoke generating agent 31 at the upper end of the thin tube 35 is started by the heating of the first coil heater 37a. At the same time, bubbles 38 made of the smoke generating agent 31 atomized by the second coil heater 37b are generated in the smoke generating agent 31 near the second coil heater 37b by the heat of the second coil heater 37b (FIG. 3 (c). )reference). When the heating is continued, the bubbles 38 grow greatly along with this, and the smoke generating agent 31 is cut off above and below the bubbles 38 (see FIG. 3D).

  When the heating is continued, the smoke generating agent 31 is heated by the second coil heater 37b, the surface tension of the smoke generating agent 31 is lowered, and the pulling up by the capillary phenomenon is stopped. ) Go down as indicated by the arrow in the middle. On the other hand, as the bubble 38 grows, the bubble 38 gains sufficient buoyancy and rises (see FIG. 3E). As the bubble 38 rises, the smoke generating agent 31 between the first coil heater 37a and the second coil heater 37b is pushed up, and atomization continues by the heating by the first coil heater 37a (FIG. 3 (f )reference). When the bubble 38 is fully raised, the fuming agent 31 that is atomized disappears, and the fuming agent 31 below the second coil heater 37b does not rise. That is, the smoke generating agent 31 existing before the heating as indicated by the arrow in FIG. 3F is consumed in one test. Thus, when the atomization of the smoke generating agent 31 necessary for one test is completed, the smoke generating agent 31 is not consumed any more.

  When the operation switch 29 is turned off and the temperature of the thin tube 35 decreases, the smoke generating agent 31 rises again by the capillary phenomenon as shown by the arrow in FIG. 2 (g) and returns to the state of FIG. 2 (a). When the operation switch 29 is turned on in this state, the same operation is repeated.

  As described above, when the operation switch 29 is turned on, only the smoke generating agent 31 necessary for one test is consumed. Further, even if the operation switch 29 is forgotten to be turned off, the smoke generating agent 31 is not consumed.

  In the present embodiment, the first cylindrical body 39a and the second cylindrical body 39b are made of ceramic. However, the first cylindrical body 39a and the second cylindrical body 39b may be made of heat resistance and insulation. For example, other materials may be used.

  In the second casing 7, for example, a rechargeable battery 49 and a circuit (not shown) for applying a voltage to the first coil heater 37 a, the second coil heater 37 b and the blower fan 23 using the battery 49 as a power source are mounted. The circuit board 27 is accommodated. When the operation switch 29 is turned on, the circuit board 27 energizes the first coil heater 37a and the second coil heater 37b, and then energizes the blower fan 23 to rotate. Further, the circuit board 27 cuts off the power supply to the first coil heater 37a, the second coil heater 37b, and the blower fan 23 when the operation switch 29 is turned off.

Next, the operation of the smoke tester 1 when performing the operation test of the smoke detector SD will be described.
When the smoke inflow part SD1 of the smoke detector SD attached to the ceiling C is covered with the silicon cover 9 of the smoke tester 1 and the smoke tester 1 itself is pushed up by the support rod, the silicon cover 9 is pivoted. It contracts in the direction of the heart, and the operation switch 29 contacts the smoke detector SD and turns on. At that time, the circuit board 27 applies a battery voltage to the first coil heater 37 a and the second coil heater 37 b, and then applies a battery voltage to the blower fan 23.

  On the other hand, the smoke generating agent 31 accommodated in the tank portion 13 is pulled up into the capillary tube 35 by capillary action. As a result of the above-described action, the smoke generator 31 that has been pulled up is nebulized in the amount of the smoke generator 31 necessary for one test, and is in the state of the mist-like smoke generator 31, that is, the smoke S. In this manner, the smoke generating agent 31 can be supplied to the inside of the thin tube 35 without using mechanical means, and only the raised smoke generating agent 31 is heated, so that it can be atomized with a small heating amount.

  The smoke S is pushed up by the wind from the blower fan 23 that flows in from the intake port 17 and is discharged from the nozzle 25 into the silicon cover 9. The smoke S composed of the mist-like smoke generating agent 31 sent into the silicon cover 9 enters from one side of the smoke inflow portion SD1 of the smoke detector SD and stays in the labyrinth of the smoke detector SD. On the other hand, part of the smoke S that has not entered the smoke detector SD passes through the smoke circulation path 21, which is a circulation means, and is discharged from the vent 19 by the suction force of the blower fan 23. Thereafter, the air flows again from the air inlet 17 into the atomizing portion casing 15 by the suction force of the blower fan 23 and circulates.

  And the smoke S which flowed in in the atomization part casing 15 is discharge | released in the silicon cover 9 again from the nozzle 25 with the mist-like smoke S heated by the 1st coil heater 37a. By repeating this circulation, smoke S having a high concentration is obtained. On the other hand, the smoke detector SD reports when the smoke S staying in the labyrinth has a concentration higher than a specified value. At this time, if the smoke detector SD does not report, it means that the smoke detector SD has failed.

  As described above, in the first embodiment, the smoke generating agent 31 can be supplied to the inside of the thin tube 35 without using mechanical means, and only the raised smoke generating agent 31 is heated. It can be atomized and the operation test of the smoke detector SD can be performed efficiently. Further, since the smoke generating agent 31 is heated by the first coil heater 37a and the second coil heater 37b wound around the first cylinder 39a and the second cylinder 39b, the smoke tester 1 having a simple structure. Can provide.

In addition, since the smoke generating agent 31 is consumed only in an amount necessary for one test by switching on once, the fuming agent 31 is not wasted even if the switch is forgotten to be turned off.
Further, since the smoke generating agent 31 is not in direct contact with the first coil heater 37a and the second coil heater 37b, the first coil heater 37a and the second coil heater 37b are not deteriorated and have a long life and can be used for a long time. It can be atomized stably.

  Further, since the smoke S composed of the mist-like smoke generating agent 31 discharged from the nozzle 25 to the smoke detector SD is circulated in the first casing 5, the concentration as the smoke S increases. That is, since the concentration of the smoke S supplied to the smoke inflow portion SD1 becomes high, the operation test of the smoke detector SD can be performed accurately in a short time.

Moreover, since the rubber plug 41 is installed in the insertion port 11 of the tank part 13, even if the smoke generating agent 31 is accommodated in the tank part 13 with liquid state, the smoke generating agent 31 does not spill out.
Moreover, since the smoke inflow part SD1 which is a part of the smoke detector SD is covered with the elastic silicon cover 9, the sealing property with the smoke detector SD can be maintained without applying excessive force. The smoke tester 1 can be provided with good workability.

In the first embodiment, the first coil heater 37a and the second coil heater 37b are heated simultaneously. However, the timing for heating the second coil heater 37b may be shifted.
For example, when the second coil heater 37b is heated first, the bubble 38 is generated and grows at an early stage, so that the fuming agent 31 above and below the bubble 38 is also separated at an early stage.
While the separation by the bubbles 38 is not performed, the smoke generating agent 31 is supplied from the tank unit 13 to the first coil heater 37a through a slight gap between the thin tube 35 and the bubbles 38 in a very small amount.
Although this is an amount that causes almost no problem, as described above, if the second coil heater 37b is heated first and the separation by the bubbles 38 is performed at an early stage, the first is more reliably performed before the start of heating. Only the smoke generating agent 31 that exists between the coil heater 37a and the second coil heater 37b can be atomized, resulting in less waste.
As another example, the second coil heater 37b may be heated later. In this case, after the smoke generating material 31 is atomized to some extent by the first coil heater 37a, bubbles 38 are generated and grow, so that even if the length of the narrow tube 53 is short, a lot of smoke S can be generated, Miniaturization is possible.
In this way, by separately providing a changing means for changing the amount of the smoke generating agent 31 to be atomized, it may be possible to cope with the test of the smoke detector SD having different sensitivities.

[Embodiment 2]
FIG. 4 is a schematic diagram showing a smoke tester 61 according to the second embodiment.
The smoke tester 61 differs from the smoke tester 1 of the first embodiment mainly in the method of discharging the smoke S to the outside, and the other configurations are common. Therefore, in FIG. 4, the same reference numerals are given to the same components as those of the smoke tester 1 of the first embodiment, and only the portions different from the first embodiment will be described below.

In FIG. 4, the external appearance of the smoke tester 61 in the second embodiment is shown in the upper part of the first casing 5 and the first cylindrical casing 5 and the second casing 7 that are integrally separated by the partition plate 3. It consists of a silicon cover 9 that is detachably mounted. The partition plate 3 is provided with a plurality of air inlets 17 in the circumferential direction only between the atomizing section casing 15 and the tank section 13. Between the first casing 5 and the atomizing section casing 15, a smoke guiding path 63 having substantially the same shape (ring shape) as the smoke circulation path 21 of the first embodiment is formed. In addition, an exhaust port 65 is provided at the lower part of the side surface of the first casing 5.
In addition, the smoke generating agent 31 is accommodated in the tank part 13, and the same atomization part 33 as the smoke tester 1 of Embodiment 1 is installed.

  The blower fan 23 provided on the lower surface of the partition plate 3 is accommodated in the second casing 7. In the center of the bottom of the second casing 7, an outside air inlet 67 for taking in outside air is provided. The battery 49 and the circuit board 27 are disposed horizontally in the second casing 7 so as to be parallel to the partition plate 3. Due to the arrangement, the length of the second casing 7 in the axial direction is shorter than that in the first embodiment. A smoke discharge hole 69 is provided on one side of the upper portion of the atomizing section casing 15, and the operation switch 29 is attached to the upper center of the atomizing section casing 15 in an exposed state.

Next, the operation of the smoke tester 61 when performing the operation test of the smoke detector SD will be described.
As described above, when the smoke inflow part SD1 of the smoke detector SD attached to the ceiling C is covered by the silicon cover 9 of the smoke tester 61 and the smoke tester 61 itself is pushed up by the support rod, The silicon cover 9 is contracted in the axial direction, and the operation switch 29 contacts the smoke detector SD and is turned on. At that time, the circuit board 27 applies a battery voltage to the first coil heater 37 a and the second coil heater 37 b, and then applies a battery voltage to the blower fan 23.

  On the other hand, the smoke generating agent 31 pulled up to the tip of the capillary tube 35 by the capillary phenomenon is heated by the first coil heater 37a to be atomized into a smoke S state. At that time, the smoke S is pushed up by the wind from the blower fan 23 flowing in from the air inlet 17 and discharged into the silicon cover 9 from the smoke discharge hole 69. The smoke S discharged into the silicon cover 9 enters from one side of the smoke inflow part SD1 of the smoke detector SD and stays in the labyrinth of the smoke detector SD. Thereafter, it flows out of the smoke detector SD and is discharged from the exhaust port 65 to the outside. In this case, the opening area of the exhaust port 65 is set so that the smoke S discharged from the exhaust port 65 is less than the smoke S discharged from the smoke discharge hole 69 of the atomizing portion casing 15, and the silicon cover 9 The concentration of the smoke S in the inside increases, and only the normal smoke detector SD reports.

  As described above, the smoke tester 61 of the present embodiment exhausts the smoke S composed of the mist-like smoke generating agent 31 discharged to the smoke detector SD little by little from the exhaust port 65 of the first casing 5 to the outside. Therefore, in addition to the effect of the smoke tester 1 of the first embodiment, there is an effect that condensation can be prevented while the smoke concentration in the silicon cover 9 is increased.

[Embodiment 3]
FIG. 5 is a schematic diagram showing a smoke tester 81 according to the third embodiment.
In the smoke tester 1 of the first embodiment and the smoke tester 61 of the second embodiment, the smoke detector SD is covered with the silicon cover 9 with the smoke tester, and the smoke S is smoked. Although it was made to flow into the sensor SD, the smoke tester 81 is largely different between the first embodiment and the second embodiment in that the smoke S is blown from a position separated by a predetermined distance.
The same components as those of the smoke tester 1 according to the first embodiment and the smoke tester 61 according to the second embodiment are denoted by the same reference numerals in FIG.

  In FIG. 5, the external appearance of the smoke tester 81 in Embodiment 3 is, for example, a rectangular first casing 5 having a partition plate 3 on the lower side, and a rectangular shape attached to one side of the first casing 5. The second casing 7 and a telescopic extension pipe 85 (for example, a multistage pipe) connected to a connection port 83 provided at the upper part of the side surface of the first casing 5. Shoulder straps 87 are attached to the upper portions of the first and second casings 5 and 7.

The partition plate 3 of the first casing 5 is provided with a tank portion 13 having a hole in the upper center. The partition plate 3 of the first casing 5 is provided with a plurality of air inlets 17 in the circumferential direction outside the tank portion 13. A blower fan 23 using a DC motor as a drive source is attached to the lower surface of the partition plate 3 of the first casing 5. Furthermore, an outside air inlet 67 for taking in outside air is provided at the bottom of the first casing 5.
In addition, the smoke generating agent 31 is accommodated in the tank part 13, and the same atomization part 33 as the smoke tester 1 of Embodiment 1 is installed.

  In the second casing 7, for example, a rechargeable battery 49 and a circuit (not shown) for applying a voltage to the first coil heater 37 a, the second coil heater 37 b, and the blower fan 23 using the battery 49 as a power source are mounted. The circuit board 27 is accommodated. A manual switch 89 such as a toggle switch is attached to the upper portion of the second casing 7. When the manual switch 89 is turned on, the aforementioned circuit board 27 energizes the first coil heater 37a and the second coil heater 37b, and then energizes the blower fan 23 to rotate. In addition, when the manual switch 89 is turned off, the circuit board 27 interrupts energization of the first coil heater 37a, the second coil heater 37b, and the blower fan 23.

Next, the operation of the smoke tester 81 when performing the operation test of the smoke detector SD will be described.
When the shoulder strap 87 of the smoke tester 81 is put on the shoulder and the tip of the telescopic extension tube 85 is pointed to the smoke inflow part SD1 of the smoke detector SD and the manual switch 89 is turned on, the circuit board 27 causes the first coil heater 37a and A battery voltage is applied to the second coil heater 37 b, and a battery voltage is applied to the blower fan 23.

  On the other hand, the smoke generating agent 31 pulled up to the tip of the capillary tube 35 by the capillary phenomenon is heated by the first coil heater 37a to be atomized into a smoke S state. At that time, the smoke S is pushed up by the wind from the blower fan 23 flowing in from the intake port 17, and flows into the telescopic extension pipe 85 from the connection port 83 provided in the first casing 5. Then, the smoke S in the telescopic extension tube 85 is discharged from the tip of the telescopic extension tube 85 to the smoke inflow portion SD1 of the smoke detector SD. On the other hand, the smoke detector SD is notified when the smoke S has a concentration equal to or higher than a specified value, and when the smoke detector SD does not issue, it is broken.

As described above, in the smoke tester 61 according to the present embodiment, since the tip of the extendable extension tube 85 is only directed toward the smoke inflow portion SD1 of the smoke detector SD, the operation test of the smoke detector SD is easy. Thus, the smoke tester 81 with good workability can be provided.
Needless to say, the smoke tester 81 of the present embodiment can also achieve the effects of the first and second embodiments.
