Improved control structure of electronic fire detection automatic fire extinguisher (III)

The present invention is an improved control structure of an electronic fire detection automatic fire extinguisher (III), and the main feature is that the fire detector of the detection circuit constitutes an OR type, or a trigger circuit for forming an AND type circuit inductively touching the annular series connection The controller of the control circuit touches the LED/buzzer to continuously flash and emit a warning, and the trigger circuit outputs a trigger voltage to break the glass bulb, sprays the fire extinguishing agent on the protection zone, and cuts off the air conditioner to prevent air from entering.

General suspended fire extinguishers, commonly known as automatic fire extinguishers, that is, fire protection law: automatic fire extinguishers set in standard fire safety equipment in various places. The automatic fire extinguisher is a container for storing fire extinguishing agent and having a nitrogen pressure push, suspending the fire extinguishing agent in the lower half, nitrogen is on, so the drug release port is also below, and the release port is provided with a temperature sensing type. The temperature probe is used to detect the fire temperature within the protection range of the fire extinguisher. The detection temperature is selected according to the characteristics of various places, the height of the ceiling and the temperature range of the ceiling affected by the ambient temperature. Different temperature sprinklers are used (Fixed Temperature Sprinkler) ). Please refer to Figure 1 for a schematic diagram of the structure of a conventional electronic fire detection automatic fire extinguisher. It can be seen from the drawings that the structure of the conventional electronic fire detection automatic fire extinguisher is mainly composed of a battery (A), a fire detector (B), and a fire extinguishing agent container (C). It is equipped with an electronic starter at the glass bulb of the fixed temperature sprinkler head. The usual electronic starter is connected to the fire detector (B) in an open state, once the fire occurs. When the surrounding temperature, smoke or flame reaches the range of the fire detector (B) induction, the fire detector (B) acts in a closed state immediately, and the battery (A) transmits current to the electronic starter to break the glass tube. The fire extinguishing agent in the fire extinguishing agent container (C) is sprayed on the protection zone to achieve the purpose of automatic fire extinguishing.

However, the battery is old or has insufficient power. It cannot be detected in advance. It cannot promote the normal operation of the fire extinguisher, and the circuit does not have the detection circuit turned on. Causes the entire circuit to be unable to know if it works properly?

Please refer to Figure 2 for a schematic diagram of the construction of a conventional electronic fire extinguisher. As can be seen from the figure, the structure of the conventional electronic detection fire extinguisher is triggered by the battery (D), the power detector (E), the smoke detector/detector detector (F), the LED/buzzer (G), and the trigger. The circuit (H) and the fire extinguishing agent container (I) are composed. The battery (D) power supply detects whether the power is sufficient via the power detector (E). When the power is insufficient, the LED/buzzer (G) flashes and sounds a warning; then the smoke detection/detection detection When any detector in the device (F) senses a fire alarm, it immediately activates the trigger circuit (H), and outputs a triggering voltage to break the glass bulb of the fixed temperature sprinkler head to spray the fire extinguishing agent in the fire extinguishing agent container (I). protected area.

However, the structure of the conventional electronic fire extinguisher lacks a power protection circuit, which is easy to cause a high power to burn the circuit, and the smoke detector/detection detector is limited to a single detector, and the fire or temperature sensing is judged to be a fire alarm, which is easy to cause The fire alarm was misjudged and the detection arrangement was only a single small area protection.

It can be seen from the above that the construction of the conventional electronic fire detection fire extinguisher and the construction of the electronic fire extinguisher have the following defects:

1. Can not detect power shortage beforehand.

2. It is impossible to detect whether the circuit is turned on beforehand.

3. Lack of power protection circuit, easy to burn the circuit.

4. Single detection smoke/detection detector is easy to cause misjudgment of fire alarm.

5. Detection arrangement is only a single small area protection

The creators of the case have alleged that the construction of the above-mentioned electronic fire detection automatic fire extinguisher and the construction of the electronic detection fire extinguisher are lacking, and based on the experience of its manufacturing, to provide "an electronic fire detection automatic fire extinguisher ( III) The control structure is improved, mainly by single or double fire detector detection method, OR action release mode (either single or dual detector) or AND action release mode (dual detector parallel) circuit, and utilize Inductively triggers the trigger circuit of the ring-connected series to flash and audible alarm. At the same time, the trigger circuit outputs a trigger voltage to break the glass bulb, sprays the fire-extinguishing agent on the protection zone, and cuts off the air conditioner to prevent air from entering, so as to achieve automatic detection and automatic fire extinguishing. The purpose of the person."

Another object of the present invention is to provide an improved control structure for an electronic fire detection automatic fire extinguisher (III), by which the control circuit can detect whether the battery power is sufficient, and the LED/buzzer continuously indirectly flashes and sings. Notice, and protect the circuit by power protection circuit The person who was burned.

A further object of the present invention is to provide an improved control structure for an electronic fire detection automatic fire extinguisher (III), wherein the fire detector of the detection circuit constitutes an OR action release mode (either single or dual detector) or an AND action The release mode (dual detector parallel) circuit is used as a dual detection circuit to make it more accurate to detect smoke, temperature, or flame, and to improve the efficiency of automatic fire extinguishing.

Another object of the present invention is to provide an electronic fire alarm detection automatic fire extinguisher (III) control structure improvement, by which a trigger circuit can be connected to a plurality of detection circuits to form a ring-connected trigger circuit, and by detecting circuit The sensing fire alarm triggers the trigger circuit, causing the controller of the control circuit to touch the LED/buzzer to continuously flash and emit a warning, and the trigger circuit outputs a trigger voltage to break the glass bulb to spray the fire extinguishing agent into the protection zone, and cut off the air conditioner. To prevent air input, it is more effective to make the automatic fire extinguishing more efficient.

The job is to improve the control structure of the electronic fire detection automatic fire extinguisher (III). The main purpose is to supply AC power or DC power from the power supply, and supply a single fire extinguisher or multiple fire extinguishers via the control circuit. The power switch device is used for starting/closing the power supply for maintenance and repair, and in combination with the test/operation switch, the trigger voltage is outputted by the pause/start trigger circuit to perform circuit test/operation.
