Abstract
The utility model discloses a photoelectric smoke and temperature sensitive fire detector, which comprises smoke sensitive elements, temperature sensitive elements, and an optical dark room. The utility model is characterized in that the smoke sensitive elements are arranged in the optical dark room, and the temperature sensitive elements and the optical dark room are positioned in the same horizontal plane; the optical dark room is designed into a circle segment shape, and the temperature sensitive elements are installed at the circle segment. The utility model not only can avoid the problem that traditional double-layer structure occupies large perpendicular space, but also can solve the problem that the radial dimension of traditional single-layer structure is enlarged; therefore, the thinned type and the miniaturisation of the photoelectric smoke and temperature sensitive fire detector is reasonably realized, and the photoelectric smoke and temperature sensitive fire detector is adapted to the requirement that modern building designs require fire detectors to be small and hidden and compatible with environment.
Description
The utility model relates to a kind of fire detector, and especially a kind of architecture advances of photoelectric smoke temperature inductive combined fire detector belongs to the fire fighting device technical field.
Existing smoke and temperature inductive combined fire detector contains thoughts cigarette element and temperature-sensing element, and sense cigarette element is placed in the circular optical dark room usually.The mounting means of temperature-sensing element has two kinds, and a kind of is to adopt double-decker, is about to temperature-sensing element and is placed in optical dark room bottom; Another kind is to adopt single layer structure, is about to temperature-sensing element and is installed in the optical dark room next door.The former takies big vertical space these two kinds of compound mounting meanss, be unfavorable for the detector slimming, the latter is because the optical dark room horizontal section is circular, in order to guarantee that temperature-sensing element obtains than highly-responsive, the detector radial dimension of just having to strengthen, the result is unfavorable for the requirement of the miniaturization of detector.
The purpose of this utility model is: the problem at above-mentioned prior art exists under the prerequisite that guarantees smoke temperature compound detection device performance, proposes a kind of photoelectric smoke temperature inductive combined fire detector with slimming, miniaturization structure.
In order to achieve the above object, photoelectric smoke heat fire detector of the present utility model contains thoughts cigarette element, temperature-sensing element, and optical dark room, and described sense cigarette component positioning is in optical dark room, and temperature-sensing element and optical dark room are located in the same horizontal plane.Described optical dark room is designed to circle and lacks shape, and described temperature-sensing element is installed in circle and lacks the place.
Because breaking the normal procedure, optical dark room is designed to the scarce shape of circle, abdicate the position and just be used on the installation temperature-sensing element, therefore the utility model both can avoid double-decker to take the bigger problem of vertical space, can solve the problem that the single layer structure radial dimension strengthens again, thereby reasonably realize slimming, the miniaturization of photoelectric smoke heat fire detector, adapt to modern building design small and exquisite, hidden to fire detector, with the requirement of environmental harmony, guarantee that again the smoke-temperature sensing performance is unaffected simultaneously.
Fig. 1 is the structural representation after embodiment of the utility model removes the detector case.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation after second embodiment of the utility model removes the detector case.
Fig. 4 is the structural representation after the 3rd embodiment of the utility model removes the detector case.
Photoelectric smoke heat fire detector illustrated in figures 1 and 2 contains thoughts cigarette element 3, temperature-sensing element 2, optical dark room 1, drain pan 4, and sense cigarette element 3 is placed in the optical dark room 1, and temperature-sensing element 2 is located in the same horizontal plane with optical dark room 1.Being shaped as with the circular both sides of straight line side cut symmetry excision small semicircle of optical dark room 1 is track and field runway shape, and its inner structure both can be the forward direction type of scattering angle greater than 90 °, also can be the backward type of scattering angle less than 90 °.Two temperature-sensing elements, 2 symmetries are installed in the circle of abdicating behind the excision small semicircle and lack the place.The optical dark room structure of this shape is simple and direct, convenient manufacturing process, and sense cigarette characteristic is good.Experiment shows, the diameter a of the photoelectric smoke heat fire detector optical dark room 1 of present embodiment at the spacing e of 30-50 millimeter, two temperature-sensing elements 2 during at the 35-75 millimeter, can guarantee all that the response speed of temperature-sensing element is unaffected and the sense smoke performance is good at 45-70 millimeter, two straight line side cut spacing b.
Embodiment illustrated in fig. 3 and difference Fig. 1 embodiment is that the scarce shape of the circle that forms behind the camber line cut-out circle is used in being shaped as of optical dark room.
Embodiment illustrated in fig. 4 and difference Fig. 1 embodiment is that the scarce shape of the circle that forms behind the broken line cut-out circle is used in being shaped as of optical dark room.
