As shown in Fig. 1 and Figure 13, photoelectricity darkroom 2 is made up of the darkroom base plate 21 being equipped with mutually and base plate lower cover 22；At the bottom of darkroom
Plate 21 and base plate lower cover 22 phase lid join be formed be positioned at center darkroom cavity 2b and around darkroom cavity 2b distribution multiple
Smog and little light can be allowed to enter into the tortuous tunnel 2a in the cavity 2b of darkroom；Multiple tortuous tunnel 2a and infrared emission dress
Put 91, infrared receiving device 92 forms an annulus around darkroom cavity 2b, infrared launcher 91 and infrared receiver just
Device 92 is directed between the center of darkroom cavity 2b, and infrared launcher 91 and infrared receiving device 92 at a distance of 135 degree extremely
139 degree, being provided with black mask shield 211 in the cavity 2b of darkroom, black mask shield 211 non smoke in the cavity 2b of darkroom makes the feelings of light scattering
It is avoided that under condition that the infrared light that infrared launcher 91 straight line is launched is received by infrared receiving device 92.In order to prevent infrared emission
The infrared light that device 91 is launched directly is received by infrared receiving device 92, setting of infrared launcher 91 and infrared receiving device 92
Putting the most on the same line, the infrared light that infrared launcher 91 sends points to the center of darkroom cavity 2b, and infrared receiver fills
Putting 92 also towards the center of darkroom cavity 2b, between infrared launcher 91 and infrared receiving device 92, optimal circumference is apart set to
137.6 degree, and it is provided with black mask shield 211 in the cavity 2b of darkroom, so in the case of the most smogless, infrared emission fills
Put 91 infrared lights sent to be received by infrared receiving device 92, only after having smog to enter darkroom cavity 2b, in smog
Fine particle, the infrared ray scattered could be received by infrared receiving device 92, thus by fire on fire time produce
Smog realize fire early detection report to the police.
In embodiment, continuing with seeing Figure 13, darkroom base plate 21 is machined with and fills infrared launcher 91 for locator card
The first locator card chamber K1 and arrange for locator card dress the second locator card chamber K2 of infrared receiving device 92 and multiple interval
And extrados has additional arc and highlights the arc block plate 21a of 21b, infrared launcher 91 is releasably installed on the first locator card chamber
In K1, infrared receiving device 92 is installed in the second locator card chamber K2 the most removedly, the tortuous tunnel described in this utility model
2a be then by two adjacent arc block plate 21a between arc tortuous spaces formed, arc highlights 21b and is then positioned at arc tortuous spaces
In, thus add the arc curvature of tortuous tunnel 2a tunnel internal, make the light in the external world substantial amounts of can not enter to darkroom cavity
In 2b.Black mask shield 211 of the present utility model is molded on darkroom base plate 21, and darkroom cavity 2b is by arc block plate 21a and first
The space that locator card chamber K1, the second locator card chamber K2 surround is constituted.
Electric supply installation 4 of the present utility model includes for the power supply of all electric units distribution electric power in fire detection alarm
Electroplax 41 and with power supply electroplax 41 circuit connect for the large-capacity battery 42 providing electric power export and press control electric power storage
Pond 42 powers the power supply bayonet lock 43 of break-make；The bottom surface of base 12 has the pilot hole 12a of power supply bayonet lock 43 assembling, and power card
The both sides of pin 43 are provided with stopper slot 43a, correspondingly the both sides of pilot hole 12a stretch out be shaped with there is appropriate elasticity can be with spacing
Groove 43a snaps in the spacing card article T of spacing cooperation.From Fig. 1, Fig. 3, Figure 10, Figure 11 and Figure 12 of the present utility model it will be seen that the end
The bottom surface of seat 12 is also machined with prominent battery compartment 12d, and accumulator 42 is arranged in the battery compartment 12d of base 12, electroplax of powering
41 location are arranged on the top of accumulator 42.The built-in accumulator 42 of this utility model is long life accumulator, in detection
When alarm dispatches from the factory, accumulator 42 is set to off-state, and now power supply bayonet lock 43 is ejection state, and therefore its height is higher than electricity
The projecting height of storehouse, pond 12d, base 12 cannot be fixed on installing plate 8 by user in this case.Before first use
Power supply bayonet lock 43 must be pressed downwards, make spacing card article T be positioned at the stopper slot 43a of power supply bayonet lock 43 i.e.: power supply is on-state.
As shown in Figure 6, installing plate 8 is the cirque structure with round and smooth tapering extrados 81, the inner circumference of this installing plate 8
It is respectively symmetrically on face and is machined with the screw recess hole 8a utilizing screw to be fixed in installation site by installing plate 8 and is used for rotating
Button hangs the fixing buckle 8b of fixing body case of annunciator 1 and for limiting the limited post 8c of body case of annunciator 1 anglec of rotation, alarm
The fixed card slot 12b that fixing buckle 8b snaps in is had on the base 12 of shell 1.First will install when installing fire detection alarm
Plate 8 is fixed on to be needed, on position to be mounted, then to be pressed by the power supply bayonet lock 43 on base 12 bottom surface and make spacing card article T snap onto
In the stopper slot 43a of power supply bayonet lock 43, then the fixed card slot 12b of base 12 is directed at fixing buckle 8b, makes fixing buckle 8b enter
Enter in fixed card slot 12b, rotate body case of annunciator 1 the most gently, make fixing buckle 8b and fixed card slot 12b coordinate clamping i.e.
Can.Fire detection alarm overall appearance of the present utility model is novel, and outward appearance is the most generous, due to screw recess hole 8a, fixes
Buckle 8b and limited post 8c is arranged on the internal ring side face of installing plate 8, and therefore installing plate 8 is mounting with body case of annunciator 1 button
After joining, screw recess hole 8a, fixing buckle 8b and limited post 8c are the most hidden inside fire detection alarm, are to see not in outside
The fit on to how.
Analog circuit and the digital circuit of precision it is furnished with on fire detection alarm main circuit board 3 of the present utility model, from
And detector work can be made more stable, reliable, the infrared electro signal that infrared receiving device 92 is inputted by main control module 31 enters
Row amplifies and is changed into digital signal by analogue signal after anti-interference process, and display module 6 is controlled by main control module 31；Without fire
Under the holding state of calamity smoke detection, the detection of every 10 seconds of fire detection alarm once, and the red LED of now display module 6
Lamp 61 flicker in every 344 seconds once, is shown to be normal mode of operation；The fire cigarette setting concentration is detected at fire detection alarm
During mist or use testing button 7 time fire detection alarm is carried out key testing, the red LED 61 of display module 6 is continuously
Piezo 5 then buzzing warning continuously while flicker.Test warning mould is then entered when pressing testing button 7 fire detection alarm
During formula, fire detection alarm will send the buzzer more than 86dB, and testing button 7 is also used for building with GSM fire alarm system
Vertical communication contact, when entering test alarm mode, main control module 31 can send alarm signal, outside making by wireless communication module 32
The GSM fire alarm system on boundary achieves after receiving and record the alarm signal of this fire detection alarm, thus realizes fire and visit
Survey the foundation of alarm and GSM fire alarm system communication contact.
Having the low-voltage alarm circuit realizing low pressure alarming function on main circuit board 3, main control module 31 contains low pressure alarming
Program, when the electricity of accumulator 42 is less than the low-pressure settings of main control module 31, main control module 31 signal of telecommunication controls piezo 5
The alarm sound sending very brief " beep " in every 43 seconds.
Main control module 31 has the history warning memory function of 24 hours, at fire detection alarm, warning once occurs
24 hours in, main control module 31 controls 3 promptings of green LED 62 interval flashing of every 43 seconds and warning once occurred.24 hours
