Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing equipment, in particular to an integrated fire extinguisher which can be manually pressed and automatically sprayed. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. As one of the common fire-fighting equipment, it is generally stored in public places or places where fires may occur to extinguish initial fires. Nowadays, fire extinguishers have entered thousands of households due to their portability and importance.

[0003] The structure of existing fire extinguishers is generally manual press type, that is, when a fire occurs, the user actively operates it. In the early stage of the fire, when the severity is small, the fire can be effectively extinguished by manually operating the fire extinguisher. However, in practice, the spread and development of fire is very rapid, and larger fires also occur from time to time. Once the fire expands, the difficulty of extinguishing it will increase accordingly, and the harm caused cannot be ignored. Since the fire situation changes very quickly, once the fire spreads, the fire extinguishers stored in various places on the scene lose their function. At the same time, it also brings safety hazards to the rescue work under high temperature. Utility Model Content

[0119] In this embodiment, the pressing mechanism is connected to one end of the bottle mouth of the bottle body and is provided with an extended tube body. The automatic temperature sensing nozzle 7 is arranged on the extended tube body and is connected to the interior of the bottle body through the manual pressing powder tube 8, so that the automatic injection and manual pressing injection share the manual pressing powder tube 8.

[0120] Specifically, the manual pressing powder tube 8 is located in the middle of the bottle body 9 and is arranged parallel to the bottle body 9 .

[0121] like Figure 3 and Figure 4 As shown, in this embodiment, the automatic temperature sensing nozzle 7 includes a nozzle frame 17, a powder splashing plate 12, a temperature sensing ball 14 and a ball seat 15;

[0122] One end of the nozzle frame 17 is adapted to the connection of the bottle body 9 and is provided with a through opening. The other end of the nozzle frame 17 is provided with the powder splashing plate 12. When the fire extinguishing agent 2 is sprayed through the automatic temperature sensing nozzle 7, the fire extinguishing agent 2 is sprayed to the surroundings based on the powder splashing plate 12, thereby expanding the coverage of the fire extinguishing agent 2.

[0123] The two ends of the nozzle frame 17 are connected into an integral structure through a protective column 18. An open cavity is provided in the middle of the nozzle frame 17. The ball seat 15 is provided at the through opening to block the through opening. The temperature sensing ball 14 is placed in the cavity. The temperature sensing ball 14 contains an expansion agent.

[0124] The expansion agent is an organic solution with different expansion coefficients, which can break the temperature-sensitive ball 14 after encountering high temperature. The temperature-sensitive ball 14 can be a glass ball.

[0125] In this embodiment, the ball seat 15 is a structure with a cross-section of an "X" shape, with one protruding end placed inside the through opening and the other end extending outwardly fitted to one end of the through opening in the cavity;

[0126] One end of the temperature sensing ball 14 abuts against the open end of the ball seat 15 , and the other end is fixed to the end of the nozzle frame 17 away from the bottle body 9 by a set screw 13 .

[0127] In this embodiment, one end of the spray head frame 17 away from the bottle body 9 is provided with an internally threaded screw opening, and one end of the set screw 13 is provided with an external thread, and the external thread is adapted to the internal thread of the screw opening.

[0128] The set screw 13 is screwed into the cavity through the outer end of the automatic temperature sensing nozzle 7 through the adapted internal and external threads, and the temperature sensing ball 14 is fixed in cooperation with the ball seat 15 .

[0129] In this embodiment, at least one side of the open end of the open cavity faces the direction of gravity of the bottle body 9 , and the opening of the open side is larger than the ball seat 15 .

[0130] Specifically, two or three protective columns 18 may be provided;

[0131] When two protective columns are provided, the two protective columns 18 are arranged opposite to each other, and the plane formed by the two protective columns 18 is perpendicular to the direction of gravity of the bottle body 9;

[0132] like Figure 5 As shown, when three protection columns are provided, the third protection column is arranged in the middle relative to the other two protection columns and is placed on the side of the bottle body in the opposite direction of gravity.

[0133] The protection column 18 may be a strip-shaped structure, an L-shaped structure or an arc-shaped structure, which is not specifically limited here.

[0134] In this embodiment, the automatic temperature sensing nozzle 7 further includes a sealing element 16 , and the sealing element 16 is disposed between the ball seat 15 and the through opening.

[0135] Based on the above-mentioned fire extinguisher structure, when it is used manually in general scenarios, the fire extinguishing agent 2 can be sprayed out through the hose 1 by the pressing mechanism to achieve fire extinguishing; when a fire breaks out in a building and cannot be extinguished, and personnel need to evacuate urgently, the manual and automatic fire extinguisher can be placed on the personnel evacuation route, and the personnel can evacuate after the automatic nozzle faces the direction of the fire risk. When the fire spreads to the manual and automatic fire extinguisher, the glass ball in the nozzle will automatically spray the agent after the thermal expansion due to the temperature to suppress the fire and slow down the spread of the fire, thereby buying precious time for the evacuation of personnel. Specifically, the fire extinguisher can be placed in a suitable position in advance through the location planning of the placement of fire-fighting equipment. For example, two fire extinguishers can be placed on both sides of the aisle with the nozzles of the two fire extinguishers facing each other. When the flame spreads, it can be extinguished directly to prevent the fire line from injuring the backs of the evacuated personnel. It can also be flexibly placed when a fire occurs.

[0136] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
