Description

  The present invention relates to a portable and highly sensitive smoke detection device that optically detects and alarms a minute smoke concentration by applying laser light to smoke particles contained in air sucked from a monitoring area.

  Conventionally, a high-sensitivity smoke detection device that detects minute smoke has been used in a clean room in a computer room or a semiconductor manufacturing facility in which a server or the like is installed. This high-sensitivity smoke detector sucks air from a sampling tube installed in the monitoring area and optically detects the number of particles floating in the air using laser light to determine the minute smoke concentration. When the smoke concentration exceeds a predetermined threshold, an alarm is output.

  In addition to the fixed installation type smoke detector that sucks air from the sampling tube, a portable smoke detector with a suction nozzle attached to the tip of the hose is placed in the monitoring area such as a computer room or clean room. When the person in charge moves the smoke detection device, the air in the place that needs to be confirmed is sucked by the suction nozzle to check the smoke density.

  According to such a portable smoke detector, there is no need to install the sampling pipe in the monitoring area in a fixed manner, and there is an advantage that the smoke density can be investigated while moving around as needed. For example, it is used in combination with a fixed installation type smoke detector that installs a sampling tube and sucks air in the monitoring area.

With a hose with a suction nozzle connected to the suction port, move it to the required place, for example, on a carriage, etc., where it sucks air from the suction nozzle at the tip of the hose and detects the smoke concentration Since the smoke detection device provided with the smoke concentration display section is separated from the suction location by the suction nozzle, there is a problem that it is difficult to perform an operation of checking the smoke density display while suctioning.

  In addition, when suctioning while moving from place to place, the suction start and stop may be repeated by operating the power switch provided on the smoke detection device side, and the power switch is turned on at the smoke detection device side away from the suction location. Since it is necessary to operate, there is also a problem that it is difficult to perform a suction operation while operating.
