Description

Air intake structure of air suction type smoke detector

Technical Field

The utility model relates to the technical field of fire-fighting detection equipment, in particular to an air inlet structure of an air suction type smoke detector.

Background

The smoke detector is a device for detecting smoke in fire-fighting alarm equipment, and has the principle that a laser emitting device is arranged in the smoke detector, smoke particles can emit laser rays if smoke enters the device, reflected rays are detected by a photoelectric device at a specific position, when the detected rays are stronger, the voltage of the photoelectric device in a circuit is higher, the smoke concentration in the air can be detected according to the principle, the smoke appearing in the surrounding environment is sensed, and an alarm signal is sent out when the smoke reaches a certain concentration, so that the purpose of preventing fire disaster is achieved. The device is commonly used in fire-fighting fire detection equipment and in the field of industrial dust detection.

The air suction type smoke detector in the prior art generally only has one air inlet pipeline, the detection area is relatively one-sided, the pipeline is narrow, air flow is relatively fast, and the rear-end detector is easy to work unstably.

SUMMERY OF THE UTILITY MODEL

In order to overcome the technical problem, the utility model provides an air intake structure of an air-breathing smoke detector, which has the following specific scheme:

an air inlet structure of an air suction type smoke detector comprises an annular pipe, wherein the bottom of the annular pipe is provided with a plurality of air inlets, and the annular pipe is connected with a transition bin through a plurality of connecting pipes; the lower part of ring conduit is equipped with the condenser, be equipped with Y type pipe in the condenser, the air inlet of Y type pipe is connected with the bottom in excessive storehouse, and the gas outlet of Y type pipe is equipped with the outlet duct that is used for being connected with the smoke detector, be equipped with the draught fan on the outlet duct, the delivery port and the header box of Y type pipe are connected, the delivery port department of header box is equipped with the solenoid valve.

Based on the above, every air intake department all is equipped with the filter screen.

Based on the above, be equipped with water level detector in the water catch box.

Compared with the prior art, the utility model has substantive characteristics and progress, and particularly has the following advantages:

according to the utility model, the bottom of the annular pipe is provided with the plurality of air inlets, and the annular pipe is connected with the transition bin through the plurality of connecting pipes, so that the structural design can introduce air in a certain area into the transition bin for detection, and the detection accuracy is improved; in addition, set up the condenser through the lower part at the ring tube, be equipped with Y type pipe in the condenser, the air inlet of Y type pipe is connected with the bottom in excessive storehouse, the gas outlet of Y type pipe is equipped with the outlet duct that is used for being connected with the smoke detector, be equipped with the draught fan on the outlet duct, the delivery port and the header box of Y type pipe are connected, this structural design can collect and carry out drying process after the hybrid buffering to the air in certain region, then discharge into the detector again and carry out assay, not only can improve the sensitivity of surveying, the accuracy, and can prevent to cause the detector air inlet to block up because of the air humidity.
