Description of drawings:
Fig. 1 is embodiment 1 structural representation of the utility model
The specific embodiment:
Below in conjunction with concrete embodiment the start-up control circuit of the portable fire extinguisher of the utility model is further explained:
Can know that by Fig. 1 the starting drive among the embodiment is mainly interconnected by power supply 1, discharge cock 2, flash alarm circuit 3, audible alarm circuit 5 and delayed startup circuit 4 and constitutes.
Wherein, It is the button cell of BT2032 that power supply 1 adopts model, and the positive pole of battery connects discharge cock 2, between the negative pole of the current output terminal of discharge cock 2 and battery, is connected with the storage capacitor C3 of a 100uF; After circuit is connected; Storage capacitor C3 begins charging, after charging is saturated, begins to discharge, and can increase the startup ability of starting drive.
Flash alarm circuit 3 is connected and composed by the 3rd resistance R 3 of LED 3 and 10K; LED 3 and the 3rd resistance R 3 are connected between discharge cock 2 and the GND each other; After extracting discharge cock 2; Electric current is got back to GND from battery through flow through LED 3 and the 3rd resistance R 3 of discharge cock 2, forms the closed-loop path, plays forewarning function thereby make LED 3 send optical signal.
Wherein: first pin of 555 chip u1 is connected to the negative pole of battery, and the 8th pin is couple on the discharge cock 2, thereby guarantees chip processing power 1; Form the loop; The 6th pin and the 7th pin couple through first resistance R 1 and discharge cock 2, and are connected to the negative pole of battery through the first filter capacitor C1, after circuit is connected; Can drag down the immediate current of the 3rd pin, make its moment keep low electricity frequently; The 4th pin is couple to discharge cock 2, the five pins through the second filter capacitor C2 ground connection, guarantees the stable work in work of circuit; The A utmost point of IGCT Q1 is couple on the discharge cock 2, and the K utmost point is connected with igniter head terminal 6 of fire extinguisher, and the G utmost point is connected to the 3rd pin of chip; The emitter stage of PNP triode Q2 is connected to second pin of chip; Grounded collector; Base stage is connected with danger button SW-PB through second resistance R 2, and the other end of danger button SW-PB is couple on the discharge cock 2, and the end of adjustable resistance R4 is couple on second resistance R 2; Other end ground connection, delay capacitor is parallelly connected with adjustable resistance R4.Like this, when pressing danger button SW-PB, circuit is connected, and electric current is from discharge cock 2 come out to flow through the danger button SW-PB and second resistance R 2; Through adjustment adjustable resistance R4 dividing potential drop, to the delay capacitor charging, the low electricity of base stage of assurance PNP triode Q2 then drags down the electricity frequency of second pin that is connected with emitter stage frequently; Make the second pin place form low electricity frequently, the electricity of the 3rd pin drags down frequently, and then the low electricity of the gate pole G of IGCT Q1 frequently; IGCT Q1 keeps off-state, and is saturated until the delay capacitor charging, and the base stage of PNP triode Q2 forms high electricity frequently; Triode breaks off, and the second pin place becomes high electricity frequently, and the 3rd pin forms the forward trigger current; IGCT Q1 puncture conducting is connected with fire extinguisher igniter head terminal 6, thereby makes the ignition circuit conducting, starts fire extinguisher.
The workflow of the utility model is: after finding the condition of a fire, at first pick up fire extinguisher and pull off the insurance draw ring, discharge cock 2 action energized 1 loop; Flash alarm circuit 3, sound and light alarm is sent in 5 work of audible alarm circuit; To remind peripheral personnel to note fire-prone, in time withdraw, also can prevent the unrelated person error starting; Press danger button SW-PB this moment, and delayed startup circuit 4 is started working, through the time-delay of 3-10s; Start fire extinguisher igniter head and implement fire extinguishing, delay time can be regulated the resistance value of adjustable resistance R4 according to actual needs.
