Abstract
The invention discloses a small fire detector comprising a shell and an internal core which are sleeved together. A sampler is rigidly connected in the internal part of the internal core. The sampler is made of L-shaped temperature-sensitive material. An optical fiber is connected on the internal core. An optical filter is arranged at the bottom part of the internal core. Clearance fitting is realized between the bottom part of the internal core and the bottom part of the shell. The bottom part of the shell is provided with a first smoke hole. The defects in the prior part can be improved, and the degree of miniaturization and integration of the fire detector can be enhanced.
Description
Technical field
The present invention relates to fire hazard monitoring technical field, especially a kind of small-sized fire detector.
Background technology
Fire causes hundreds of millions of economic losses and great casualties every year in China, so fire disasters protection is a very important measure in safety in production life.Existing fire detector not only volume is large, cannot install and use in some narrow space, and function singleness, or only photosensitive or sense cigarette, makes the monitoring of fire there is blind spot.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of small-sized fire detector, can solve the deficiencies in the prior art, improves miniaturization and the integration degree of fire detector.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of small-sized fire detector, comprise the shell and kernel that are set in together, kernel internal rigid is connected with sampling thief, sampling thief is made up of L-type thermo-sensitive material, kernel is connected with optical fiber, the bottom of kernel is provided with optical filter, and the bottom of kernel coordinates with the bottom gap of shell, and the bottom of shell is provided with the first cigarette hole.
As preferably, the top of described kernel is provided with the second cigarette hole and flue, and the second cigarette hole is connected with flue, and the top of shell is provided with the 3rd cigarette hole.
As preferably, described 3rd cigarette hole and the first cigarette hole lay respectively at the both sides of shell.
As preferably, described flue is semi-circular recesses.
As preferably, described shell adopts copper coin to make.
As preferably, described shell is cube, and its length is 6mm, and width is 3.8mm, is highly 3.6mm.
As preferably, described shell seals cementation calmly by aviation glue and kernel.
The beneficial effect adopting technique scheme to bring is: the present invention reduces the volume of fire detector effectively, and be integrated with sense cigarette, sense flame and the multiple detection mode of temperature-sensitive, parameter sampling precision is high, can realize early warning to fire simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural drawing of inner housing in the present invention's embodiment.
Fig. 2 is the structural drawing of the present invention's embodiment China and foreign countries housing.
In figure: 1, shell; 2, kernel; 3, sampling thief; 4, the 3rd cigarette hole; 5, optical fiber; 6, optical filter; 7, the first cigarette hole; 8, the second cigarette hole; 9, flue.
Embodiment
The standardized element used in the present invention all can be commercially, shaped piece all can carry out customized according to instructions with the record of accompanying drawing, the concrete connected mode of each part all adopts the conventional means such as bolt, rivet, welding, stickup ripe in prior art, is not described in detail in this.
With reference to Fig. 1-2, the present invention's embodiment comprises the shell 1 and kernel 2 that are set in together, kernel 2 internal rigid is connected with sampling thief 3, sampling thief 3 is made up of L-type thermo-sensitive material, kernel 2 is connected with optical fiber 5, the bottom of kernel 2 is provided with optical filter 6, and the bottom of kernel 2 coordinates with the bottom gap of shell 1, and the bottom of shell 1 is provided with the first cigarette hole 7.The top of kernel 2 is provided with the second cigarette hole 8 and flue 9, second cigarette hole 8 and is connected with flue 9, and the top of shell 1 is provided with the 3rd cigarette hole 4.3rd cigarette hole 4 and the first cigarette hole 7 lay respectively at the both sides of shell 1.Flue 9 is semi-circular recesses.Shell 1 adopts copper coin to make.Shell 1 is cube, and its length is 6mm, and width is 3.8mm, is highly 3.6mm.Shell 1 is determined by aviation glue and kernel 2 envelope cementation.Short of the L-type of sampling thief 3 is coupled with light, and the light through optical filter 6 also can be coupled with light by short of the L-type of sampling thief 3.When there is smog, smog enters kernel 2 from the space of the first cigarette hole 7 and optical filter 6 surrounding, and smog stops the light between optical fiber 5 and sampling thief 3, thus the reflection ray light quantity in optical fiber is reduced, and detector sends warning message.When there being thermal current to flow to detector, reflector is heated and bends, thus the reflection angle between sampling thief 3 and optical fiber is changed, thus the light quantity entering optical fiber is changed, and detector sends warning message.When flame is near detector, flame injects the space of reflector and fiber end face by optical filter, and the light quantity entering optical fiber is increased, and detector sends warning message.Second cigarette hole 8, the 3rd cigarette hole 4 and flue 9 can form a smoke flow passage be communicated with the first cigarette hole 7, thus improve the precision of smoke detection.
The present embodiment volume is little, and installation site is flexible, and functional integration is high, can realize early stage accurate early warning to fire.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
