Abstract
The utility model discloses a fire extinguishing apparatus which is capable of solving the problem that the existing fire extinguishers are incapable of realizing automatic alarm when the fire happens. The fire extinguishing apparatus is characterized in that a pressure indicator, a nozzle, a safety pin and a handle are arranged on an extinguisher head, wherein the extinguisher head is arranged at the top of a fire extinguisher main body; a power switch is arranged on a battery pack; the battery pack and an integrated circuit board are arranged on a shell of the fire extinguisher main body; and the integrated circuit board consists of a resistor R1, a resistor R2, a resistor R3, a thermistor R4, a resistor R5, a variable resistor R6, a variable resistor R7, a resistor R8, a resistor R9, a resistor R10, a smoke sensor M1, a diode D1, a light emitting diode D2, a diode D3, a buzzer M2, a triode parent tube Q1, a triode parent tube Q2 and a comparator M3. The fire extinguishing apparatus provided by the utility model is simple, convenient, low in cost and easy for popularization.
Description
Technical field
The utility model relates to the fire-fighting equipment field, particularly a kind of extinguishing device.
Background technology
Present fire extinguisher does not possess the function that the automatic alarm people of meeting when fire takes place are arranged.Because it is sudden that the generation of fire mostly has, people often feel to be caught unprepared or are terrified flurried, and cause people can't judge the on-site particular location of fire extinguisher exactly.Delay the Best Times of fire extinguishing, made fire extinguisher not bring into play the due effect of its institute's tool, finally caused fire to have brought tremendous loss for people's economic life.
Summary of the invention
The design's purpose is: solved existing fire extinguisher can not be realized automatic alarm after fire takes place problem, and a kind of extinguishing device that provides.
Technical scheme:
The utility model is by the fire extinguisher main body, pressure indicator, and nozzle, safety plug, handle, battery pack, power switch, surface-mounted integrated circuit and device head are formed.It is characterized in that pressure indicator, nozzle, safety plug, handle are arranged on the device head, wherein the device head is arranged on the top of fire extinguisher main body, and power switch is arranged on the battery pack, and battery pack and surface-mounted integrated circuit are arranged on the shell of fire extinguisher main body, and wherein surface-mounted integrated circuit is by resistance R 1; Resistance R 2, resistance R 3, thermistor R4, resistance R 5, variable resistor R6; Variable resistor R7, resistance R 8, resistance R 9, resistance R 10; Smoke Sensor M1, diode D1, light emitting diode D2, diode D3; Buzzer M2, triode parent tube Q1, triode parent tube Q2, compositions such as comparator M3.
Beneficial effect:
The design has overcome fire extinguisher in the prior art not to be possessed as defective that can automatic alarm when fire takes place.And a kind of extinguishing device of design.
1 when air themperature surpasses the temperature range of thermistor R4 setting; Thermistor R4 carries out one to the in-phase input end of comparator M3 and relatively produces a high level signal through importing a voltage; High level signal drives buzzer M2 through triode parent tube Q2 and sends warning, and driven for emitting lights diode D2 realizes sound and light alarm simultaneously.
2 when the air smokescope is provided with the scope of smokescope above Smoke Sensor M1; Smoke Sensor M1 carries out one to the in-phase input end of comparator M3 and relatively produces a high level signal through importing a voltage; High level signal drives buzzer M2 through triode parent tube Q1 and sends warning, and driven for emitting lights diode D2 realizes sound and light alarm simultaneously.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the design is further specified.
(the same section label is consistent among each figure)
Fig. 1 is the design's an overall structure sketch map;
Fig. 2 is the circuit diagram among the design.
Among the figure: 1. fire extinguisher main body, 2. pressure indicator, 3. nozzle, 4. safety plug, 5. handle, 6. battery pack, 7. power switch, 8. surface-mounted integrated circuit, 9. device head.
The specific embodiment
Like Fig. 1-shown in Figure 2, pressure indicator, nozzle, safety plug, handle are arranged on the device head, and wherein the device head is arranged on the top of fire extinguisher main body, and power switch is arranged on the battery pack, and battery pack and surface-mounted integrated circuit are arranged on the shell of fire extinguisher main body; Wherein surface-mounted integrated circuit is by resistance R 1, resistance R 2, resistance R 3, thermistor R4, resistance R 5; Variable resistor R6, variable resistor R7, resistance R 8, resistance R 9, resistance R 10; Smoke Sensor M1, diode D1, light emitting diode D2, diode D3; Buzzer M2, triode parent tube Q1, triode parent tube Q2, compositions such as comparator M3.
When air themperature surpasses the temperature range of thermistor R4 setting; Thermistor R4 carries out one to the in-phase input end of comparator M3 and relatively produces a high level signal through importing a voltage; High level signal drives buzzer M2 through triode parent tube Q2 and sends warning, and driven for emitting lights diode D2 realizes sound and light alarm simultaneously.
When the air smokescope is provided with the scope of smokescope above Smoke Sensor M1; Smoke Sensor M1 carries out one to the in-phase input end of comparator M3 and relatively produces a high level signal through importing a voltage; High level signal drives buzzer M2 through triode parent tube Q1 and sends warning, and driven for emitting lights diode D2 realizes sound and light alarm simultaneously.
