The pins of a temperature response devices are connected with the analog input ports of a monolithic on the fume and temperature detecting circuit board, a probes of the temperature response devices extends outside the shell, two through holes are arranged on the upper wall of the shell which are symmetrically arranged along the axis of the shell, the number of the temperature response devices is two, every probe of the temperature response device separately extends through a through hole, the two sides of the every through hole on the outside of the shell are separately provided with a guarding ridge, the probe of the temperature response device is disposed between the two guarding ridges on the two sides of the through hole. The fume and temperature complex detector is characterized by a high sensitivity and reliability to the test of the direction of the temperature and the time response, further the appearance is thin.
Description
Technical field
The utility model relates to fire-alarm, and specifically a kind of smog and temperature to the smoldering fire that produces black smoke surveyed, thereby realizes the smoke temperature compound detection device of fire alarm by alarm.
Background technology
Temperature sensing device on the existing cigarette temperature detector is independently one, and for guaranteeing cigarette temperature explorer response threshold value and the consistance of response time, independently temperature sensing device is arranged on the center of detector housing usually.There is following shortcoming in above-mentioned cigarette temperature detector: temperature sensing device fast inadequately to temperature-responsive independently, and sensitive inadequately to the orientation response of temperature; Independently in a single day temperature sensing device breaks down, and detector promptly can be malfunctioning.In addition, independently temperature sensing device stretches out at the center position of detector housing projection, and the monnolithic case of detector is increased, and modern requirement to detector is ultra-thin attractive in appearance.
Summary of the invention
The purpose of this utility model is to provide the test sensitivity of a kind of orientation to temperature, time response, the smoke temperature compound detection device that reliability is high, and it also has the thin characteristics of profile.
For achieving the above object, the utility model adopts following scheme:
Base plate is stamped in the lower end of housing, the cigarette temperature detection circuit plate that is positioned at housing is loaded on the base plate, single-chip simulation input port on the pin of temperature sensing device and the cigarette temperature detection circuit plate joins, the probe of temperature sensing device stretches out outside the housing, the roof of housing is provided with two through holes, two through holes are along the axis symmetric arrangement of housing, temperature sensing device is two, the probe of each temperature sensing device stretches out from a through hole respectively, two limits of each through hole of hull outside respectively are installed with a root guard muscle, and the probe of temperature sensing device is between the two protection muscle on through hole two limits.Protrude in the middle of the roof of housing, through hole is positioned on the lower end face in the roof projection outside.
The temperature parameter that two temperature sensing devices collect not only can be used as the compensation of aflame smog parameter, effectively survey various test fires (comprising the black smoke that polyurethane plastics, normal heptane burning produce), and two temperature sensing devices can be independent collecting temperature information, to survey the temperature variation in each orientation delicately.The protection muscle that each through hole two limit is provided with plays the protective effect to temperature sensing device, and the probe that prevents to stretch out the temperature sensing device of housing is collided with and damages.In addition, even two temperature sensing devices have a damage, another also can independently be worked, and compares with adopting a temperature sensing device in the existing detector, and reliability improves.And temperature sensing device is arranged on the lower face in the housing top wall projection outside, and the height of housing is reduced.
Description of drawings
The structural drawing of Fig. 1 the utility model one embodiment;
The vertical view of Fig. 2 Fig. 1.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1
Base plate 2 is stamped in the lower end of housing 1, and cigarette temperature detection circuit plate 8 is loaded on the base plate 2, identical in cigarette temperature detection circuit plate 8 and the existing cigarette temperature detector.On cigarette temperature detection circuit plate 8 radome 7 is housed, radome 7 covers light acceptance, the emitting area of cigarette temperature detection circuit plate 8.Single-chip simulation input port on the pin of temperature sensing device 5 and the cigarette temperature detection circuit plate 8 joins, and temperature sensing device 5 adopts thermistor.Protrude in the middle of the roof of housing 1, both the middle part of housing 1 be a boss 1 ', boss 1 ' sidepiece have window 9, in housing 1, be installed with the wire netting 6 of retaining at window 9 places.It more than is prior art.Through hole 4 on the roof of housing 1 is positioned on the lower end face in the roof projection outside, and two through holes 4 are along the axis symmetric arrangement of housing 1.Two edges of each through hole 4 of housing 1 outside respectively are installed with a root guard muscle 3, the inboard hollow out of protection muscle 3.Temperature sensing device 5 is two, and the probe of each temperature sensing device 5 stretches out from a through hole 4 respectively, and the height of temperature sensing device 5 probes is lower than protection muscle 3.
Referring to Fig. 2
Two edges of each through hole 4 respectively are installed with a root guard muscle 3, and the probe of temperature sensing device 5 is between the two protection muscle 5 on through hole 4 two limits.Boss 1 ' and the low end face in the outside between be provided with reinforcement 10.
The protection muscle does not block the less thermistor of volume, so just can not cause the smog that enters detector direction and block.Though and the darkroom, labyrinth that is used to survey smog in the housing can cause the air-flow of thermistor perception smog temperature and block, the employing of two temperature sensing devices of the utility model can remedy this disappearance.This detector can accomplish neither to influence the smoke detection performance, can not influence the temperature-responsive time again to be subjected to the orientation to change conforming test.This detector joins by bus and alarm, detects the small amount of thermal energy that smoldering fire is discharged by detector when burning, and can realize fire alarm by alarm.
