Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, and in particular to an intelligent electronic start-up device for fire extinguishers. Background Technology

[0002] Existing fire extinguishers generally use solenoid valve extinguishing devices, which have insufficient opening time, leading to the escalation of the fire. When filling the extinguishing agent cylinder, the entire control module must be carried along, making operation inconvenient. The overall structural dimensions are also relatively large, requiring significant installation space. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent electronic activation device for fire extinguishers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent electronic activation device for fire extinguishers includes a fire extinguishing activation valve assembly installed on a fire extinguishing cylinder. A nozzle communicating with the inside of the fire extinguishing cylinder is provided on one side of the fire extinguishing activation valve assembly. The fire extinguishing activation valve assembly includes a movably mounted cam. A sealing piston is installed inside the fire extinguishing activation valve assembly via a spring. The sealing piston is used to seal the end of the nozzle near the fire extinguishing cylinder. A siphon tube is provided inside the fire extinguishing cylinder. After the nozzle and the fire extinguishing cylinder are connected, the siphon tube guides the extinguishing agent in the fire extinguishing activation valve assembly into the nozzle. A reset pin, a manual trigger ring, and an automatic trigger are provided on one side of the fire extinguishing activation valve assembly.

[0005] Preferably, the top of the fire extinguishing cylinder is provided with a pressure relief port, which can release the pressure when the pressure inside the fire extinguishing cylinder is too high, thus ensuring overall safety.

[0006] Preferably, one end of the cam corresponds to the position of the sealing piston.

[0007] Preferably, the fire extinguishing cylinder is filled with a fire extinguishing agent.

[0008] Preferably, the extinguishing agent is liquid perfluorohexanone.

[0009] Preferably, the automatic trigger contains an electronic match.

[0010] The beneficial effects of this utility model are as follows: This invention employs electronic activation, achieving millisecond-level pipeline opening for highly efficient fire extinguishing. The overall structure is compact and cost-effective; a manual knob facilitates filling the extinguishing agent cylinder, making it convenient to carry and operate. A pressure relief port is included to automatically discharge extinguishing agent when the filling pressure is too high, preventing the danger of overfilling. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] In one embodiment, refer to Figures 1 to 3 A smart electronic activation device for fire extinguishers includes a fire extinguishing activation valve assembly 11 installed on a fire extinguishing cylinder 10. A nozzle 4 communicating with the inside of the fire extinguishing cylinder 10 is provided on one side of the fire extinguishing activation valve assembly 11. The fire extinguishing activation valve assembly 11 includes a movably configured cam 6. A sealing piston 3 is installed inside the fire extinguishing activation valve assembly 11 via a spring. The sealing piston 3 is used to seal the end of the nozzle 4 near the fire extinguishing cylinder 10. A siphon tube 2 is provided inside the fire extinguishing cylinder 10. After the nozzle 4 and the fire extinguishing cylinder 10 are connected, the siphon tube 2 guides the extinguishing agent 1 inside the fire extinguishing activation valve assembly 11 to the nozzle 4. A reset pin 7, a manual trigger ring 8, and an automatic trigger 5 are provided on one side of the fire extinguishing activation valve assembly 11.

[0015] When the fire extinguishing signal is triggered, the automatic trigger 5 detonates. The explosive force of the automatic trigger 5 pushes the cam 6 to move. At this time, the sealing piston 3 moves upward under the action of the spring. The movement of the sealing piston 3 makes the nozzle 4 and the fire extinguishing cylinder 10 internally connected. The extinguishing agent 1 in the fire extinguishing cylinder 10 is guided to the nozzle 4 through the siphon tube 2 and sprayed out to extinguish the fire. After the fire is extinguished, the reset pin 7 is pulled to reset the cam 6. The cam 6 drives the sealing piston 3 to reset downward, thereby sealing one end of the nozzle 4 and closing the connection between the nozzle 4 and the fire extinguishing cylinder 10. When manual operation is required, the manual trigger ring 8 is pulled up, which in turn pulls the cam 6 and the sealing piston 3 to move, connecting the nozzle 4 and the fire extinguishing cylinder 10.

[0016] In a preferred embodiment of this utility model, the top of the fire extinguishing cylinder 10 is provided with a pressure relief port 9. When the pressure inside the fire extinguishing cylinder 10 is too high, it can be discharged through the pressure relief port 9 to ensure overall safety.

[0017] In a preferred embodiment of this utility model, one end of the cam 6 corresponds to the position of the sealing piston 3.

[0018] In a preferred embodiment of this utility model, the fire extinguishing cylinder 10 is filled with fire extinguishing agent 1.

[0019] In a preferred embodiment of this utility model, the extinguishing agent 1 is liquid perfluorohexanone.

[0020] In a preferred embodiment of this utility model, the automatic trigger 5 contains an electronic match.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
