Composite smoke and temperature sensing fire detecting device

Abstract

The invention provides a composite smoke and temperature sensing fire detecting device including an air collecting cover, a smoke suction base, a small air suction fan, a pt100 temperature sensor, a connecting base and a lamp socket; the top surface of a detection seat supports a function seat through a supporting rod, the function seat is of a round cavity structure, and a small suction fan is arranged in the inner cavity of the function seat; three air pipes are arranged on the outer side of the small suction fan in a penetrating mode, the air pipes penetrate through the outer side of the function seat to be bent downwards; a mounting table with an annular structure is arranged on the top surface of the function seat, and a bolt hole used for installing the whole device on the ceiling ofthe house is formed in the mounting table; when the smoke rises upwards, the raised smoke can rise to the detector quickly, the receiving of the smoke signals are accelerated, an alarm is quickly sent, the signal early warning speed is increased, and the low-concentration smoke is generated even when the smoke rises upwards, the air suction and gathering effects of the three upward air suction pipes which are uniformly distributed are achieved, the smoke can be rapidly ascended into the sensing base, and the smoke concentration is improved.

Description

technical field [0001] The invention belongs to the technical field of smoke detection seat structure, and more specifically relates to a composite smoke and temperature fire detection device. Background technique [0002] The fire detector is the equipment used in the automatic fire alarm system to detect the scene and find the fire. The fire detector is the "sensory organ" of the system, and its function is to monitor whether there is a fire in the environment. Once there is a fire, the characteristic physical quantities of the fire, such as temperature, smoke, gas and radiant light intensity, are converted into electrical signals, and immediately act to send an alarm signal to the fire alarm controller. [0003] The inventor found similar patents for tree injection in the process of searching for patents. For example, the application number is: a buzzer base for fire detectors disclosed in CN201620378006.7, its basic description In order to include: a housing, a PCB boa...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a composite smoke-sensing and temperature-sensing fire detection device to solve the problem that after the above-mentioned existing detector with a hanging structure is installed on the roof of the house, the fire source on the ground of the house is upward due to the inconsistent height of the room space. The rising smoke cannot reach the position where the detection sensor seat is located quickly, and because the concentration of the smoke rises to the detector position is not uniform, it is possible that the concentration of smoke near the position of the sensor sensor seat of the detector is too thin, making the sensing effect And it seems that it is so ideal, so it will lead to the problem that the detection and induction time is too long
