And warning circuit, described power-supplying circuit provides circuit voltage, and smoke detection circuit receives the detectable signal of cigarette sense detecting head
And outputting signals to microprocessor, the output signal of microprocessor is sent to wireless radio frequency modules and warning circuit；Described cover body
It is provided with several perforates as smog window, and a rotary handle that can rotate relative to cover body is interted at the top of cover body,
The end of described rotary handle connects runing rest, is provided with Clean Brush for cleaning, described Clean Brush for cleaning position at the two ends of runing rest
Top in cigarette sense detecting head.
Described perforate is long shape hole, arranges a more than circle at the circumference of cover body top differing heights.
Described microprocessor uses the MSP430 single-chip microcomputer of low-power consumption, and the radio frequency chip in wireless radio frequency modules uses band to answer
Answer the CC1101 of pattern.
Described cigarette sense detecting head uses HQ-2 Smoke Sensor.
The beneficial effects of the utility model are: perception accuracy rate is high, it is possible to accurately detection fire dangerous situation, inside easy cleaning
Pollutant and impurity, it is ensured that personal safety as well as the property safety.
This utility model uses wireless communication technique to combine with cigarette sense Detection Techniques, is possible not only to the standalone probe condition of a fire,
The effect of fire-fighting link can be played with fire-fighting host communication simultaneously.
This utility model uses 433MHz wireless communication technique, uses the low-consumption wireless radio frequency core of the band answer-mode of TI
Sheet, is possible not only to the two-way intercommunication of the information that realizes, also reduces system power dissipation；Use 9V lithium electricity, it is ensured that detector is at electricity simultaneously
Normally can be worked under the electric power thus supplied of pond 6-8, decreases user and changes the trouble of battery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structured flowchart of circuit main board.
Fig. 3 is circuit theory diagrams of the present utility model.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of wireless smoke alarm of trigger-type, it includes base 1, is arranged on described base 1
Cover body 2, be positioned at the detector body 3 of described cover body 2, its described detector body 3 includes circuit main board, cigarette sense detecting head
4 and buzzer 5, described circuit main board is provided with power-supplying circuit 6, smoke detection circuit 7, microprocessor 8, less radio-frequency mould
Block 9 and warning circuit 10, described power-supplying circuit 6 provides circuit voltage, smoke detection circuit 7 to receive cigarette sense detecting head 4
Detectable signal also outputs signals to microprocessor 8, and the output signal of microprocessor 8 is sent to wireless radio frequency modules 9 and electricity of reporting to the police
Road 10；Described cover body 2 is provided with several perforates 11 as smog window, and the top of cover body 2 intert one can relatively cover
The rotary handle 12 that body rotates, the end of described rotary handle 12 connects runing rest 13, sets at the two ends of runing rest 13
Clean Brush for cleaning 14, described Clean Brush for cleaning 14 is had to be positioned at the top of cigarette sense detecting head 4.
As it is shown on figure 3, power-supplying circuit 6 uses transformator T blood pressure lowering, diode VD1, VD2 all wave rectification, power supply electricity
Hold C filtering, and after Zener diode VZ voltage stabilizing, the DC voltage of output about 5V, supply circuit uses.Described smoke detection
Circuit 7 uses HQ-2 Smoke Sensor to gather smoke signal, and supply voltage supplies HQ-2 Smoke Sensor after resistance R1 blood pressure lowering
Filament heating, smog detected once HQ-2 Smoke Sensor, its electrical conductivity increases rapidly so that it is outfan connect electricity
