Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, specifically to an electromagnetic pulse air pressure spray water gun. Background Technology

[0002] A pulse pressure spray water gun is a fire extinguishing tool that uses compressed air as power to instantly spray a high-speed atomized water jet into the center of a fire, producing a cooling, suffocating, and isolating effect to extinguish the fire. Powered by compressed air, it mixes rapidly expanding compressed air with water, then sprays a high-speed, ultra-fine water mist in a pulse. This water mist effectively controls the spread of fire and extinguishes it quickly and efficiently. The pulse pressure spray water gun is designed for safety, simplicity, and portability, allowing for rapid deployment to locations difficult for rescue vehicles, such as narrow streets, urban-rural fringe areas, and high-rise buildings. Its high mobility and flexibility enable it to quickly reach the fire scene and extinguish the fire. Its low or no pollution characteristics mean it causes virtually no secondary damage to buildings, equipment, or personnel, and there is almost no secondary property damage caused by fire-fighting water stains. The pulse pressure spray water gun has a wide range of applications, capable of directly extinguishing electrical fires without creating a circuit, and is suitable for various fields such as solid fires, gas fires, and petrochemical fires. However, the power source of the pulse pressure spray water gun is high-pressure gas. While water can be virtually unlimited during firefighting, the gas volume in high-pressure cylinders is still limited. Pulse pressure spray water guns are heavy, reducing their maneuverability. Furthermore, their large size makes them inconvenient to carry. Therefore, those skilled in the art have developed electromagnetic pulse pressure spray water guns to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide an electromagnetic pulse air pressure spray water gun to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An electromagnetic pulse air pressure spray water gun includes an electromagnetic pulse spray water gun body, an internal structure, and an external structure. The internal structure is fixedly connected to the inside of the electromagnetic pulse spray water gun body, and the external structure is fixedly connected to the outside of the electromagnetic pulse spray water gun body. The internal structure includes: a water storage chamber, a water inlet pipe, a support rod, a connecting guide rod, a firing coil, a reciprocating piston, a reciprocating piston limiting block, an energy storage device, and a power supply. A water storage chamber is provided at the front end of the interior of the electromagnetic pulse spray water gun body. A water inlet pipe is fixedly connected to the lower end of the water storage chamber and to the bottom of the exterior of the electromagnetic pulse spray water gun body. The interior of the water inlet pipe is connected to the interior of the water storage chamber.

[0006] As a further embodiment of this utility model: a support rod is fixedly connected to one end of the interior of the electromagnetic pulse spray water gun body, and a connecting guide rod is fixedly connected to one side surface of the support rod and located inside the electromagnetic pulse spray water gun body.

[0007] As a further embodiment of this utility model: a transmitting coil is fixedly connected to the surface of the connecting guide rod and to the front side of the support rod, and a reciprocating piston is movably connected to the surface of the connecting guide rod and to the front side of the transmitting coil.

[0008] As a further embodiment of this utility model: a reciprocating piston limiting block is fixedly connected to the surface of the connecting guide rod and to the front side of the reciprocating piston, and an energy storage device is fixedly connected to the upper end of the electromagnetic pulse spray water gun body.

[0009] As a further improvement of this utility model: a power source is fixedly connected to the lower end of the body of the electromagnetic pulse spray water gun, and the energy storage device and the power source are located on the rear side of the support rod.

[0010] As a further embodiment of this utility model: the external structure includes: a rubber front baffle, a star-shaped opening, a water gun handle and a water gun handle anti-slip sleeve, and the rubber front baffle is fixedly connected to the front surface of the electromagnetic pulse spray water gun body.

[0011] As a further improvement of this utility model, the front surface of the rubber front baffle is provided with a cross-shaped opening made by a cutter.

[0012] As a further embodiment of this utility model: a water gun handle is fixedly connected to the bottom of the electromagnetic pulse spray water gun body and to the rear side of the water inlet pipe, and a water gun handle anti-slip sleeve is fixedly fitted on the surface of the water gun handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. First, fire extinguishing agent (water or other water-based fire extinguishing agent) is injected into the water storage chamber through the water inlet pipe. The transmitting coil is connected to the power supply through an electrical wire, and the power supply is connected to the energy storage device through an electrical wire. Under the action of the magnetic force of the transmitting coil, the reciprocating piston slides at high speed on the surface of the connecting rod. The movement of the reciprocating piston pushes the fire extinguishing agent (water or other water-based fire extinguishing agent) inside the water storage chamber out of the star-shaped opening on the surface of the rubber front baffle for fire extinguishing.

[0015] 2. The function of the reciprocating piston limiting block on the surface of the connecting guide rod is to prevent the reciprocating piston from detaching from the surface of the connecting guide rod during movement. The electromagnetic pulse spray water gun body uses electromagnetism as a power source, which is much better than high-pressure gas. It is also lighter than pulse air pressure spray water guns, making it more convenient and flexible in terms of mobility. Carrying a backup power supply is much lighter and smaller than carrying a backup gas cylinder. Attached Figure Description
