[0022] Please see Figure 1-5 The present invention provides a technical solution: a long-lasting fire extinguishing device, comprising a fire extinguisher bottle 1 and a combination mechanism 2, wherein the combination mechanism 2 is provided on one side of the surface of the fire extinguisher bottle 1;

[0023] The combined mechanism 2 includes an external thread 201, a sealing ring 202, a connecting cover 203, a connecting plate 204, a connecting groove 205, a first slot 206, a slide 207, a handle 208, a flat nozzle 209, a positioning post 210, a spring 211, a long rod-type pressure handle 212, a rubber block 213, a second slot 214, and a safety pin 215. The surface of the fire extinguisher cylinder 1 is provided with an external thread 201. A sealing ring 202 is installed at the rim of the fire extinguisher cylinder 1. The surface of the external thread 201 is threadedly connected to the connecting cover 203. A connecting plate 204 is fixedly connected to one side of the connecting cover 203. The interior of the connecting cover 203... A connecting groove 205 is provided, a first slot 206 is provided at one end of the connecting cover 203, a sliding groove 207 is provided on one side of the connecting cover 203, a handle 208 is fixedly connected to one side of the surface of the connecting cover 203, a flat nozzle 209 is installed inside the connecting groove 205, a positioning post 210 is fixedly connected to one side of the sliding groove 207, a spring 211 is connected to one side of the sliding groove 207, a long rod-type pressure handle 212 is fitted into the surface of the positioning post 210, a rubber block 213 is installed on the pressing arc surface of the long rod-type pressure handle 212, a second slot 214 is provided at one end of the long rod-type pressure handle 212, and the second slot 214 is fitted inside. With a safety pin 215, and through the arrangement of external thread 201, sealing ring 202, connecting cover 203, connecting plate 204, connecting groove 205, first slot 206, slide groove 207, handle 208, flat nozzle 209, positioning post 210, spring 211, long rod type handle 212, rubber block 213, second slot 214, and safety pin 215, under normal circumstances, the safety pin 215 is engaged in the first slot 206 and the second slot 214 to prevent the long rod type handle 212 from being accidentally touched or misoperated. When the fire extinguisher needs to be used, first pull out the safety pin 215 to unlock the handle mechanism, allowing the long rod type handle 212 to be engaged. The handle 212 can be pressed freely. The user holds the handle 208 and presses the long handle 212 with force. Since the long handle 212 forms a sliding structure with the positioning post 210 and the spring 211, when pressed, the long handle 212 will move downward along the slide groove 207. At the same time, the rubber block 213 provides a comfortable pressing experience. The long handle 212 covers the flat nozzle 209. When the handle is pressed, the handle is removed, and the pressurized extinguishing agent enters the flat nozzle 209 through the connecting groove 205 and is sprayed out evenly. Since the connecting groove 205 fits the inner diameter of the fire extinguisher bottle 1, it ensures that the extinguishing agent flows out smoothly.

[0024] Furthermore, the other side of the sealing ring 202 is fitted with the connecting cover 203. Two sets of sealing rings 202 are provided. Through the setting of the sealing rings 202, the sealing rings 202 are installed on the surface of the fire extinguisher cylinder 1 and are tightly fitted with the connecting cover 203. Its main function is to prevent the extinguishing agent from leaking from the interface of the cylinder during the use of the fire extinguisher. The sealing ring 202 effectively ensures that the pressure inside the fire extinguisher is maintained, ensuring that the extinguishing agent can be sprayed out smoothly and efficiently. At the same time, the sealing ring 202 plays a key sealing role between the connecting cover 203 and the fire extinguisher cylinder 1. It fills the tiny gap between the cylinder and the connecting cover 203, preventing the leakage of gas or liquid.

[0025] Furthermore, the other side of the long lever handle 212 covers the flat nozzle 209. The long lever handle 212 and the flat nozzle 209 form a sliding structure through the spring 211. The main function of the flat nozzle 209 is to spray the extinguishing agent in the fire extinguisher. Through its connection with the connecting groove 205, it ensures that the extinguishing agent passes smoothly through the long lever handle 212 and is sprayed out from the nozzle. The nozzle design allows the extinguishing agent to be dispersed around the fire source in a more uniform and flat spray pattern, increasing the extinguishing area and improving the extinguishing efficiency.

[0026] Furthermore, one side of the connecting groove 205 is fitted with the inner diameter of the fire extinguisher cylinder 1, and one side of the sealing ring 202 is fitted with the connecting groove 205. Through the setting of the connecting groove 205, the main function of the connecting groove 205 is to serve as a channel between the fire extinguisher cylinder 1 and the flat nozzle 209. When the fire extinguisher is activated, the extinguishing agent flows out from the cylinder, enters the nozzle through the connecting groove 205, and is sprayed onto the fire source. It provides a smooth path to ensure that the flow of the extinguishing agent is not obstructed.

[0027] Furthermore, spring 211 is located on the outside of positioning post 210, and the other side of spring 211 is connected to long rod handle 212. Through the setting of spring 211, spring 211 is connected to long rod handle 212 and positioning post 210. Its main function is that when the user releases the handle, the reverse elastic force provided by spring 211 will reset long rod handle 212 to its original position. This reset function can ensure that the fire extinguisher stops quickly after spraying, prevent the extinguishing agent from continuing to flow out, and ensure the safety and efficiency of use.

[0028] Furthermore, the positioning post 210 is provided in two sets. The long rod type pressure handle 212 forms a mutual sliding structure with the positioning post 210 through the spring 211. The main function of the positioning post 210 is to ensure that the long rod type pressure handle 212 slides along the correct trajectory during the pressing process. Through its structural design, the positioning post 210 enables the pressure handle to move stably in the predetermined direction within the slide groove 207, thereby avoiding pressure handle deviation or jamming and ensuring smooth operation of the fire extinguisher.

[0029] Furthermore, the first slot 206 and the second slot 214 are positioned opposite each other, and the other end of the safety pin 215 is fitted inside the first slot 206. With the arrangement of the first slot 206, the second slot 214 and the safety pin 215, when the user needs to use the fire extinguisher, the safety pin 215 must first be pulled out from the first slot 206 and the second slot 214 to unlock the mechanism. After the safety pin 215 is pulled out, the long lever handle 212 can be pressed down freely, thereby activating the spray function of the fire extinguisher. This design ensures that the fire extinguisher is safe when not in use, and can be quickly activated in an emergency.

[0030] Furthermore, multiple sets of rubber blocks 213 are provided. The rubber blocks 213 are distributed at equal intervals and angles on the pressing arc surface of the long-handled handle 212. The main function of the rubber blocks 213 installed on the pressing arc surface of the long-handled handle 212 is to improve the user's comfort when pressing. The elasticity and softness of the rubber can effectively reduce the pressure on the hand, avoid discomfort when pressing for a long time, improve the operating experience, and make the use of the fire extinguisher more user-friendly.

[0031] Working principle: Under normal circumstances, the safety pin 215 is engaged in the first slot 206 and the second slot 214 to prevent the long lever handle 212 from being accidentally touched or misoperated. When the fire extinguisher needs to be used, first pull out the safety pin 215 to unlock the handle mechanism, so that the long lever handle 212 can be pressed freely. The user holds the handle 208 and presses the long lever handle 212 with force. Since the long lever handle 212 forms a sliding structure with the positioning post 210 and the spring 211, when pressed, the long lever handle 212 will move downward along the slide groove 207. At the same time, the rubber block 213 provides a comfortable pressing experience. The long lever handle 212 covers the flat nozzle 209. When the handle is pressed, the handle is removed, and the pressurized extinguishing agent enters the flat nozzle 209 through the connecting groove 205 and is sprayed out evenly. Since the connecting groove 205 fits the inner diameter of the fire extinguisher bottle 1, it ensures that the extinguishing agent flows out smoothly.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
