Abstract
The utility model discloses a kind of flame detectors, infrared fileter, ultraviolet filter including detector housing and at the top of detector housing, detector housing between infrared fileter, ultraviolet filter is equipped with gas outlet, condenser is being equipped with close to top position in detector housing, detector housing lower part is equipped with temperature sensor, temperature sensor is connected to the input terminal of controller, and the output end of controller is connect with fire alarm module and solenoid valve respectively, and solenoid valve connects gas source.The utility model has the beneficial effects that light-ray condensing is improved detector sensitivity by the design of condenser, alarm response speed is fast；The temperature sensor of setting, it can be decided whether to start cooling of blowing according to the temperature in current device, avoid equipment hot soak condition, guarantee the service life of equipment, the gas of blowout comes out from gas outlet simultaneously, the sundries on optical filter can be cleared up, so that the translucency that optical filter has also been able to maintain after a protracted use.
Description
Technical field
The utility model relates to technical field of fire detection, relate in particular to a kind of flame detector.
Background technique
With the rapid development of economic construction of China, the quantity of volumed space building and hypogee is continuously increased, these ground
Side is often densely populated, and loss caused by generation fire incident is inestimable, and therefore, the fire-fighting security work of these occasions is especially
Seem important.But existing fire alarm generally uses flame detector, flame detector in use generally there are
Following problems: (1) prolonged use causes to cover with one layer of heavy bits on optical filter, seriously affects the translucency of optical filter, in turn
Influence the sensitivity of flame detector；(2) flame detector for fire spot is made because under hot soak condition
At service life；(3) in addition to this, the detection range of flame detector is limited, and to will cause sensitivity inadequate apart from too long, so that
Fire detection ability is limited, and the flame brightness of detection must be bright enough, and flame must be sufficiently large.
Utility model content
For the problems in the relevant technologies, the utility model proposes a kind of flame detectors, solve existing flame detector
There are problems that sensitivity is inadequate, service life is short and optical filter pollution.
In order to achieve the above technical purposes, technical scheme of the utility model is as follows:
A kind of flame detector, infrared fileter, purple including detector housing and at the top of the detector housing
Outer optical filter, the detector housing between the infrared fileter, ultraviolet filter are equipped with gas outlet, the detector housing
Inherent to be equipped with condenser close to top position, the detector housing lower part is equipped with temperature sensor, and the temperature sensor connects
It is connected to the input terminal of controller, the output end of the controller is connect with fire alarm module and solenoid valve respectively, the electromagnetism
Valve connects gas source.
Further, the infrared fileter and ultraviolet filter use optically flat filter, arc optical filter or spheric
Optical filter.
Further, the bottom of the detector housing is equipped with pedestal.
Further, the infrared fileter, ultraviolet filter are fastened on detector housing.
The utility model has the beneficial effects that light-ray condensing is improved detector sensitivity, alarm by the design of condenser
Fast response time；The temperature sensor of setting can decide whether to start cooling of blowing according to the temperature in current device, avoid setting
Standby hot soak condition guarantees the service life of equipment, while the gas blown out comes out from gas outlet, can clear up optical filter
On sundries so that the translucency that optical filter has also been able to maintain after a protracted use.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model

A little attached drawings obtain other attached drawings.
Fig. 1 is a kind of structural schematic diagram of flame detector according to the utility model embodiment.
In figure:
1, detector housing；2, fire alarm module；3, condenser；41, infrared fileter；42, ultraviolet filter；5, go out
Port；6, temperature sensor；7, solenoid valve；8, controller.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in Figure 1, a kind of flame detector, including detector housing 1 and set on the red of 1 top of detector housing
Outer optical filter 41, ultraviolet filter 42, the detector housing 1 between the infrared fileter 41, ultraviolet filter 42 are equipped with
Gas outlet 5, the detector housing 1 is interior to be equipped with condenser 3 close to top position, and 1 lower part of detector housing is equipped with temperature
Spend sensor 6, the temperature sensor 6 is connected to the input terminal of controller 8, the output end of the controller 8 respectively with fire
Alarm module 2 and solenoid valve 7 connect, and the solenoid valve 7 connects gas source.
In a specific embodiment, the infrared fileter 41 and ultraviolet filter 42 use optically flat filter, arc
Shape optical filter or spheric optical filter.
In a specific embodiment, the bottom of the detector housing 1 is equipped with pedestal.
In a specific embodiment, the infrared fileter 41, ultraviolet filter 42 are fastened on detector housing 1
On.
When in use, the light detection that flame detector detection is penetrated according to infrared fileter 41, ultraviolet filter 42 is to fiery
Flame signal, then fire alarm module 2 issues alarm signal, and instruction people take measures, and after a period of time, works as temperature sensor
6 reach set temperature, and controller 8 controls solenoid valve 7 and opens, and start to cool down, then to blowing air inside flame detector
The gas being discharged from flame detector secondary can be used to blow away infrared fileter 41, the dirt on ultraviolet filter 42.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
