[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, the partition plate 3 of the first casing 5 is provided with a plurality of air inlets 19 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. FIG. 2A illustrates a state where the atomizing unit 33 is not operated, and FIG. 2B illustrates a state where the atomizing unit 33 is operated and the smoke generating agent 31 is atomized.

As shown in FIG. 2, the atomizing section 33 is composed of a thin tube 35 serving as a smoke generating agent lifting member that is immersed in the smoke generating agent housed in the tank portion 13 at one end and pulls the smoke generating agent 31 to the other end. It has a coil heater 37 as a heating means that heats the smoke generating agent 31 provided on the other end side and pulled up. The coil heater 37 is wound around and attached to a ceramic cylinder 39 installed on the upper portion of the 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.

  In the present embodiment, the smoke generating agent pulling member is constituted by a glass thin tube 35, and the tube wall of the thin tube 35 functions as a partition wall of the present invention that prevents contact between the smoke generating agent 31 and the coil heater 37.

<Coil heater>
The coil heater 37 heats the upper end portion of the thin tube 35 or the entire upper portion of the thin tube 35 exposed from the tank unit 13 to atomize the smoke generating agent 31 pulled up to the upper end portion of the thin tube 35. It is one aspect | mode of the heating means of invention. The coil heater 37 is formed of, for example, nichrome wire, but the material is not particularly limited.
In the present embodiment, the coil heater 37 is wound around a ceramic cylinder 39.
Since the smoke generating agent 31 is in the glass thin tube 35 and the coil heater 37 is wound around a ceramic cylinder 39 installed on the outer periphery of the thin tube 35, the coil heater 37 contacts the smoke generating agent 31. There is nothing.
The reason why the coil heater 37 is 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. When the residue adheres to the coil heater 37, the coil heater 37 deteriorates, and the atomization of the smoke generating agent 31 cannot be continuously performed.

In the present embodiment, since the smoke generating agent pulling member is composed of the glass thin tube 35, the tube wall of the thin tube 35 serves as a partition wall as described above, and the smoke generating agent 31 can be used as a coil heater without the cylinder 39. 37, the coil heater 37 may be wound directly around the thin tube 35.
However, by winding the coil heater 37 around the cylindrical body 39 so that the thin tube 35 and the cylindrical body 39 can be inserted and removed, an effect of facilitating replacement work when the thin tube 35 is contaminated with residue can be obtained.
The cylindrical body 39 also functions as a reinforcing material that prevents damage such as the thin tube 35 from being broken.

In addition, as shown in FIG. 3, the cylindrical body 39 is good also as the taper-shaped cylindrical cylindrical body 40 diameter-reduced as it goes to a front-end | tip part. With such a shape, heat is more easily transmitted to the distal end portion of the thin tube 35, and on the other hand, heat is less likely to be transmitted to the proximal end side, so that the temperature is higher at the distal end portion of the narrow tube 35 and lower at the proximal end portion. .
By using the circular tapered cylindrical cylindrical body 40, the cylindrical cylindrical body 40 functions as the heating temperature adjusting means of the present invention.
The reason for providing the cylindrical tube 40 as the heating temperature adjusting means is as follows.
By warming the smoke generating material 31 at the proximal end side and the intermediate portion of the thin tube 35, the temperature of the smoke generating material 31 supplied to the distal end side can be raised in advance to facilitate atomization. On the other hand, if the temperature of the proximal end side and the intermediate portion of the narrow tube 35 is too high, the smoke generating agent 31 may be atomized on the proximal end side and the intermediate portion of the narrow tube 35. Therefore, by providing a cylindrical tube body 40 as a heating temperature adjusting means, the temperature is higher at the distal end portion and lower at the proximal end portion, so that atomization at the proximal end side and the intermediate portion of the thin tube 35 is achieved. Atomization at the tip can be reliably performed while suppressing the above.

  In the present embodiment, the cylindrical body 39 is formed of ceramic, but the material of the cylindrical body 39 may be other materials as long as it has heat resistance and insulation.

  The second casing 7 houses, for example, a rechargeable battery 49 and a circuit board 27 on which a circuit (not shown) for applying a voltage to the coil heater 37 and the blower fan 23 is mounted using the battery 49 as a power source. ing. When the operation switch 29 is turned on, the circuit board 27 energizes the coil heater 37 and then energizes the blower fan 23 to rotate. The circuit board 27 cuts off the power supply to the coil heater 37 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 battery voltage is applied to the coil heater 37 by the circuit board 27 and the battery voltage is applied 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. The raised smoke generating agent 31 is atomized by being heated by the coil heater 37, and becomes a mist-like smoke generating agent 31, that is, a state of 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, a 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 ventilation path 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.

  Then, the smoke S that has flowed into the atomizing section casing 15 is discharged again into the silicon cover 9 from the nozzle 25 together with the mist-like smoke S heated by the coil heater 37. 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 accommodated in the tank unit 13 is pulled up into the narrow tube 35 using the capillary phenomenon, and the smoke generating agent 31 thus lifted is heated and atomized by the coil heater 37. The mist-like smoke generating agent 31 is forcibly discharged as smoke S to the smoke detector SD by the blower fan 23.
In this way, the smoke tester 1 can be pulled up into the narrow tube 35 without using mechanical means to supply the smoke generating agent 31, and only the pulled smoke generating agent 31 is heated. Therefore, the operation test of the smoke detector SD can be efficiently performed. Furthermore, since the heating of the smoke generating agent 31 is performed by the coil heater 37 wound around the cylindrical body 39, the smoke addition tester 1 having a simple structure can be provided.
Further, since the smoke generating agent 31 is not in direct contact with the coil heater 37 by the partition wall, the coil heater 37 is not deteriorated, has a long life, and can be stably atomized even when used for a long time.

  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 above description, the example in which the smoke generating agent 31 lifting member is configured by the glass thin tube 35 is shown, but the smoke generating agent 31 lifting member may be formed of a porous material such as ceramic.
An example of the atomization part which formed the smoke generating agent 31 raising member with the porous material is shown in FIG. The atomizing portion 43 shown in FIG. 4 has a cylindrical porous member 45 and a permeation preventing member 47 that is installed on the porous member 45 and serves as a partition wall. The permeation preventing member 47 may be cylindrical or may be wound around the porous member 45. The permeation preventing member 47 has a shape that covers the outer periphery of the porous member 45 and is thermally conductive so that the smoke generating agent 31 does not ooze out. If it is a material, it will not specifically limit.

  The porous member 45 has a large number of thin grooves on the surface, and the smoke generating agent 31 can be lifted upward by capillary action as in the case of the thin tube 35 described above. In the case of the porous member 45, since the smoke generating agent 31 can enter from the entire peripheral surface in contact with the smoke generating agent 31, the pulling property is good. Therefore, for the purpose of preventing the smoke generating agent 31 from spilling out from the tank portion 13, as shown in FIG. 4, the absorbent cotton 51 or the like is accommodated in the tank portion 13 and the absorbent cotton 51 or the like is impregnated with the absorbent cotton 51 or the like. Also good. In this case, the rubber plug 41 is not necessary.

[Embodiment 2]
FIG. 5 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. 5, the same reference numerals are given to the same components as those in the smoking tester 1 of the first embodiment, and only portions different from the first embodiment will be described below.

In FIG. 5, 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 battery voltage is applied to the coil heater 37 by the circuit board 27 and the 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 coil heater 37 to be atomized into a state of smoke S. 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 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 due to the setting of the opening area of the exhaust port 65, and the smoke S in the silicon cover 9. And the normal smoke detector SD only 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. 6 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.
In addition, the same code | symbol is attached | subjected in FIG. 6 to the same thing as the smoke tester 1 which concerns on Embodiment 1, and the smoke tester 61 which concerns on Embodiment 2. FIG.

  6, the appearance of the smoke tester 81 in the third embodiment 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.

  The second casing 7 accommodates, for example, a rechargeable battery 49 and a circuit board 27 on which a circuit (not shown) for applying a voltage to the coil heater 37 and the blower fan 23 is mounted using the battery 49 as a power source. ing. 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 circuit board 27 energizes the coil heater 37 and then energizes the blower fan 23 to rotate. Further, the circuit board 27 cuts off the power supply to the coil heater 37 and the blower fan 23 when the manual switch 89 is turned off.

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 directed to the smoke inflow portion SD1 of the smoke detector SD and the manual switch 89 is turned on, the battery voltage is applied to the coil heater 37 by the circuit board 27. Then, the 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 coil heater 37 to be atomized into a state of smoke S. 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 81 according to the present embodiment, since the tip of the extendable extension tube 85 is only directed toward the smoke inflow part 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.
