Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoke detector inspection device for inspecting a smoke detector installed on a ceiling or the like.

[0002]

2. Description of the Related Art As a smoke detector inspection device of this type, there is, for example, one shown in FIG. This one has an air intake 18
a, a ventilation unit 18 having an air outlet 18b, a blower 5 disposed in the ventilation unit 18 for generating an airflow from the air intake 18a side to the air outlet 18b side, and the smoke disposed in the ventilation unit 18. And a blower 5 and a control unit 7 that is connected to the smoke generator 6 and controls the operating states thereof.

This smoke detector inspection device is used as shown in FIG. That is, one end of the ventilation part 18 is brought close to or in contact with the smoke detector A installed on the ceiling or the like, and the wind containing the smoke generated by the smoke generator 6 is sent to the smoke detector A to detect the smoke. Check reaction of vessel A. At this time,
Smoke sensor A responds to smoke and sends a sensing signal to the receiver,
From the alarm issued by the receiver, it can be seen that the smoke detector A operates normally. After the alarm is issued, the smoke generator 6 is controlled to stop the smoke generation, and the smoke-free wind is sent to discharge the smoke accumulated in the smoke detector A. As a result, the receiver can be restored from the alarm state to the normal state, and the inspection work of other smoke detectors can be started.

[0004]

By the way, in the above-mentioned one, the control unit 7 controls the generation of smoke by changing the voltage applied to the heater of the smoke generator 6,
A smoke-containing wind and a smoke-free wind are switched. However, when switching from a smoke-free wind to a smoke-containing wind, it takes time until the heater becomes sufficiently hot and smoke is generated after applying a predetermined voltage to the smoke generator 6, which is a waste of inspection work. There was a long waiting time. On the other hand, when switching from a smoke-containing wind to a smoke-free wind, even if the voltage applied to the smoke generator 6 is reduced to the extent that smoke is not generated, there is preheating and it takes time until smoke stops. However, there was a problem in that it was not possible to move quickly to the next smoke detector inspection work.

When the ventilation part 18 is brought into contact with the smoke sensor A for inspection, the housings of the smoke sensor A and the ventilation part 18 are made of a slippery material such as plastic or metal. Therefore, there is a problem that the ventilation part 18 is easily slippery with respect to the smoke sensor A, and it is difficult to position and blow air as desired, which makes inspection work difficult. On the other hand, if the ventilation part 18 is strongly pressed against the smoke sensor A to be fixed, the smoke sensor A and the ventilation part 18 may be damaged and, in extreme cases, may be damaged.

The present invention has been made in view of the above circumstances. A first object of the present invention is to provide a smoke detector inspection device capable of efficiently performing the smoke detector inspection work. is there. A second object of the present invention is to provide a smoke detector inspection device that can be in good contact with the smoke detector for inspection work.
