Description

TECHNICAL FIELD

[0001] The utility model relates to smoke detector technical field, specifically point to a kind of condensate water collection automatic water drainer of suction type smoke detector with check valve. BACKGROUND

[0002] Suction type smoke detector is an advanced fire detection equipment. It extracts the air sample in the surrounding environment by built-in air extraction device. When working, air is sucked into the sampling pipe network of the detector. The pipe network, like a sharp antenna, can extend to every corner of the protected area, even hidden spaces are not overlooked. The high-precision sensor inside the detector will analyze the collected air. Once the smoke particle concentration exceeds the preset threshold, the alarm will be triggered immediately. Compared with traditional smoke detectors, it can detect fire earlier and more accurately, which can save valuable time for personnel evacuation and fire rescue, and is widely used in data centers, machine rooms, warehouses and other places.

[0003] In actual use scene, the temperature difference of the environment where suction type smoke detector is located changes frequently. Especially when the outside temperature drops sharply or the indoor and outdoor temperature difference is large, condensate water is easy to appear in the air extraction device. This is because the water vapor in hot air will quickly condense into liquid water when it meets cold. On the one hand, these condensate water will adhere to the wall of air extraction pipeline, increase air resistance, and then seriously affect the air extraction effect, so that the detector is difficult to efficiently collect air sample. On the other hand, if the water continues to increase and penetrates into the device, it may also contact the electronic components, causing short circuit and other faults, which endangers the normal operation of the whole detector.

[0007] The three-way pipe is connected to the sampling pipe and the host computer connection pipe at both ends to form a communication pipeline.

[0008] The condensate water collection mechanism includes a collection pipe and a collection box. The collection pipe is connected to the other end of the three-way pipe, and the collection box is fixedly arranged at the lower end of the collection pipe.

[0014] Compared with the prior art, the three-way pipe connects the sampling pipe, the host computer connecting pipe and the collecting pipe, and a clear and reasonable gas-liquid flow channel is constructed. The gas enters through the sampling pipe, can be normally conveyed along the host computer connecting pipe after passing through the three-way pipe, and the gas supply required by the related functions of the air suction type smoke detection device is ensured. The condensate water and water vapor generated in the gas flow process in the host computer connecting pipe can accurately flow to the collecting pipe through the three-way pipe, so that the condensate water and water vapor have a clear and fixed movement direction, and the situation of chaotic backflow does not occur.

[0015] The collecting pipe is connected to the collecting box, once the condensate water flows into the collecting box, the accurate monitoring of the liquid level by the water level detector and the cooperative action of the drain pipe and the check valve can timely drain the condensate water at the appropriate liquid level, avoid the influence of the condensate water accumulation on the normal operation of the equipment, and thus ensure the stable and efficient work of the entire air suction type smoke detection device.
