[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] 1. The utility model provides a portable fire extinguisher. By hitting the surface of the connecting block with a hard object, the connecting block is forced to move downward and the card block is pressed off. At this time, the air outlet moves upward relative to the connecting block, so that the air outlet pushes the limit plate 1 outward upward and breaks the restraint of the limit plate 2. At this time, through the effect of the internal pressure of the bottle body, the gas inside the bottle body is quickly ejected through the air outlet to extinguish the fire in the place where the fire is larger, thereby effectively controlling the spread of the fire and improving the fire extinguishing effect. By not equipping the bottle body with a spray assembly, the fire extinguisher can store more fire extinguishers in a limited space, thereby avoiding the situation where there are not enough fire extinguishers in an emergency.

[0017] 2. The utility model provides a portable fire extinguisher. By taking out the injection assembly and aligning the threaded rod with the top of the connecting block, the threaded rod is driven to rotate by rotating the connecting rod. At this time, the fixed block moves downward through the threaded connection between the threaded rod and the threaded groove. When the fixed block contacts the limit plate, the connecting rod continues to be rotated. At this time, the fixed block continues to move downward and destroys the limit plate. At this time, the gas in the bottle body enters the connecting rod through the air outlet. At this time, one hand holds the pressure handle and the other hand holds the nozzle and aims at the fire source. By pressing the pressure handle, the gas in the bottle body is sprayed out through the nozzle to extinguish the fire source. The pressure handle can be released to stop spraying. When the gas in the bottle body is used up, the connecting rod can be rotated in the opposite direction to separate the injection assembly from the bottle body, and a new bottle body filled with gas can be connected to the injection assembly for continued use. Therefore, one injection assembly can be equipped with multiple bottles, so that the fire extinguisher can reduce the waste of resources during production and occupy less space.

At this time, the gas in the bottle body 1 can be sprayed out through the action of the injection assembly 3 to extinguish the fire source.

[0026] like Figure 2 As shown, in the present embodiment, blocks 22 are fixedly connected to both sides of the inner wall of the connecting cover 21, a connecting block 27 is fixedly connected to the top of the inner wall of the connecting cover 21, an air outlet 23 is fixedly connected to the middle of the bottom of the inner wall of the connecting cover 21, a limiting plate 24 is fixedly connected to the top of the air outlet 23, a limiting plate 25 is fixedly connected to the top of the limiting plate 24, a circular cylinder 26 is fixedly connected to the outer side of the bottom of the limiting plate 25, the bottom of the outer wall of the circular cylinder 26 is fixedly connected to the bottom of the inner wall of the connecting block 27, a threaded groove 28 is fixedly connected to the top of the inner wall of the connecting block 27, and the top of the inner wall of the connecting block 27 is threadedly connected to the bottom of the outer wall of the threaded rod 31.

[0027] In specific implementation, when an emergency situation occurs and the fire is large, the surface of the connecting block 27 is hit with a hard object, so that the connecting block 27 is forced to move downward and break the block 22. At this time, the air outlet 23 moves upward relative to the connecting block 27, so that the air outlet 23 pushes the limit plate 1 24 outward and breaks through the restraint of the limit plate 25. At this time, through the action of the internal pressure of the bottle body 1, the gas inside the bottle body 1 is quickly ejected through the air outlet 23 to extinguish the fire in the place where the fire is large, thereby effectively controlling the spread of the fire and improving the fire extinguishing effect. By not equipping the bottle body with an injection assembly 3, the fire extinguisher can store more fire extinguishers in a limited space, thereby avoiding the situation where there are not enough fire extinguishers in an emergency.

At this time, the fixing block 32 moves downward through the threaded connection between the threaded rod 31 and the threaded groove 28. When the fixing block 32 contacts the limit plate 24, the connecting rod 34 is continuously rotated. At this time, the fixing block 32 continues to move downward and destroys the limit plate 24. At this time, the gas in the bottle body 1 enters the connecting rod 34 through the gas outlet 23. At this time, one hand holds the Hold the pressure handle 35 with one hand and hold the nozzle 38 and aim it at the fire source. By pressing the pressure handle 35, the gas in the bottle body 1 is sprayed out through the nozzle 38 to extinguish the fire source. Release the pressure handle 35 to stop spraying. When the gas in the bottle body 1 is used up, the connecting rod 34 can be rotated in the opposite direction to separate the spray assembly 3 from the bottle body 1, and a new bottle body 1 filled with gas can be connected to the spray assembly 3 for continued use. In this way, one spray assembly 3 can be equipped with multiple bottle bodies 1, so that the fire extinguisher can reduce waste of resources during production and occupy less space.
