Specific embodiment
Below with reference to the accompanying drawings embodiments of the present invention are described more fully.Being provided for of embodiment makes this hair
It is bright more detailed, and protection scope is adequately conveyed to those skilled in the art.Elaborate that numerous specific details is for example specific
Position, device example, to provide detailed understanding to embodiments of the present invention.To those skilled in the art will
It is evident that embodiment can be implemented with many different forms and not necessarily be applicable in these specific details, therefore they
It shall not be construed as limiting the scope of the invention.In addition, being retouched in an attached drawing of the invention or a kind of embodiment
The elements and features stated can be combined with elements and features shown in one or more other drawings or embodiments.?
In some embodiments, in order to understand purpose, the well-known process that is not described in detail in the drawings and in the description, knot
Structure and technology.
Such as the overall structure of the explosion figure that Fig. 4 is smoke detector in the present invention, smoke detector includes upper casing 20, into cigarette fan
Palace 10 is arranged in into detection probe, circuit board 40 and the lower casing 30 below 10 pedestal 1 of cigarette labyrinth.Smoke detector is generally logical
It crosses lower casing 30 to be mounted on the ceiling for needing to carry out smoke detection space, offers on upper casing 20 and opened convenient for what air entered
Mouthful.Air in ambient enviroment is entered in detector by the opening on shell, and today is into the use in cigarette labyrinth 10
In the cavity 5 of detection smokescope.The space and cavity 5 that detection probe on pedestal 1 can be detected are interconnected.Detection
Probe is connected on circuit board 40, and the signal detected is analyzed and turned by chip on circuit board 40 and component
It changes, finally carry out fire behavior alarm or continues to test.
It is as shown in Figure 1 the structural schematic diagram in the present embodiment into cigarette labyrinth 10, includes pedestal 1 and upper cover into cigarette labyrinth 10
4, the cavity 5 for detecting smokescope is formed between upper cover 4 and pedestal 1, gas enters detection from the upper casing 20 of detector
After in device, through filter screen 7, the insect carried in air or large particle are blocked in into 10 outside of cigarette labyrinth by strainer 7, prevent
Insect or large particle block fume inlet passage 6 after entering, and influence detector detection.Cavity 5 is surrounded by 16 block baffles 2,
This 16 block baffle 2 is along the circumferential uniformly arrangement in 5 periphery of cavity.As shown in Figures 2 and 3, it is all formed between every two adjacent screen 2
Enter the fume inlet passage 6 in cavity 5 for ambient atmos, smog enters in cavity 5 from fume inlet passage 6.In the present embodiment, ten
Six baffles 2 are arranged in upper cover 4, and whens installation or removal only needs to lift upper cover 4 and labyrinth structure can be taken, just
In inspection and cleaning.In order to facilitate the installation and use of each detector, it is equipped with battery in the smoke detector in the present embodiment,
Smoke detector only passes through power supply power supply, and is equipped with wireless communication module, removes the worry of connection data line from.
The base shape of each baffle 2 is identical, is fork type, and contacting into cigarette one end with strainer 7 for baffle 2 is another
End is divided into two, and forms two first bifurcateds 21 and the second bifurcated 22.Wherein, the length of the first bifurcated 21 is less than the second bifurcated 22,
Second bifurcated 22 protrudes into cavity 5, and the one end for protruding into cavity 5 is tilted to side.In this way, the second bifurcated 22 forms one and half
The situation of encirclement, the first bifurcated 21 of baffle 2 adjacent at this time extend with corresponding second bifurcated, 22 direction, protrude into the second bifurcated
In 22 semi-surrounding circle, and then form the fume inlet passage 6 of " C " type.
As shown in Figures 2 and 3, in order to enable it is more uniform into cigarette effect, it include several sketch plates 3 in 16 baffles 2,
Protrusive board 31 on sketch plate 3 is arranged on the second bifurcated 22, and baffle 2 and sketch plate 3 are in one-to-two, then divide two form, similar
In fork type.In the present embodiment, there are four sketch plate 3 is set, and the protrusive board 31 being arranged on 3 plate of each sketch plate prolongs to unprecedentedly interior
The angle and depth stretched are different, and four sketch plates 3 are distributed in the not equally distributed specific position of surrounding cavity 5.This
Sample, the fume inlet passage 6 formed between different baffles 2 or sketch plate 3 is distributed in different angles, to cooperate the peace of detection probe
Dress supervision, enables to smoke-sensitive alarm device performance more excellent.Wherein, in this implementation, it is in 135 ° or so that detection probe, which is a pair of,
The luminous tube and reception pipe of angle are to shot-light seat, and strainer 7 is metal screen 7.
Detect environment in gas by fume inlet passage 6 enter cavity 5 to be detected in, into the pedestal 1 in cigarette labyrinth 10 on set
There is the window 11 for detecting smokescope and for gas outflow, in order to facilitate airflow and guarantees that airflow is steady
Fixed, window 11 is provided with position corresponding to 5 middle part of cavity, and detection probe can carry out smokescope by window 11 real-time
Detection.
