[0036] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0037] Please also read Figures 1 to 5The embodiment of the present application provides a fire extinguishing stick, which includes a handle 10, a spray cartridge 20 and a bottom cover 30. The handle 10 is provided with a first end 11 and a second end 12 at opposite ends thereof, the spray cartridge 20 stores medicine, and a control component 40 is installed in the handle 10. One end of the spray cartridge 20 has a nozzle 201, and the other end is detachably connected to the outer periphery of the first end 11. The middle part of the second end 12 has an opening 101. The control component 40 is provided with a pull ring 41 exposed from the opening 101, and the pull ring 41 is pulled out by a user to trigger the spray cartridge 20 to spray medicine from the nozzle 201. The bottom cover 30 is detachably connected to the outer periphery of the second end 12 to close the opening 101. A support member 50 is connected to the outer peripheral wall of the bottom cover 30, a blade 60 is installed between the opposing surfaces of the support member 50 and the bottom cover 30, and a window breaker 70 is installed on the surface of the support member 50 away from the bottom cover 30.

[0038] By arranging the handle 10, the spray cartridge 20 and the bottom cover 30 to cooperate with each other, the user can control the spray cartridge 20 to spray the agent to extinguish the fire by holding the handle 10 and pulling out the pull ring 41 of the control component 40. The pull ring 41 is placed at the opening 101 of the second end 12. When the fire extinguishing stick is not in use, the bottom cover 30 is installed on the outer periphery of the second end 12 to close the opening 101 to prevent the pull ring 41 from being touched by mistake. When the fire extinguishing stick needs to be used, the bottom cover 30 can be removed from the second end 12 to close the opening 101. The end 12 is disassembled to expose the pull ring 41 from the opening 101 of the second end 12, so that the user can pull out the pull ring 41, thereby triggering the spray cartridge 20 to spray the agent from the nozzle 201, and the fire extinguishing stick is more convenient to use; the bottom cover 30 is equipped with a blade 60 and a window-breaking hammer 70 through the support 50, the blade 60 is used to cut the car seat belt, and the window-breaking hammer 70 is used to smash the car window, so that the fire extinguishing stick can be suitable for more application scenarios and the fire extinguishing stick has richer functions.

[0039] Specifically, a first accommodating cavity for placing the control component 40 is formed inside the handle 10, and the opening 101 is connected to the first accommodating cavity. A second accommodating cavity for placing the medicine is formed inside the spray barrel 20, and the nozzle 201 is connected to the second accommodating cavity.

[0040] Specifically, the agent can be a solid-state mixed agent of potassium and strontium ions. The agent is safer when stored in solid form. During the fire extinguishing process, potassium salt and strontium salt will produce potassium strontium ion aerosol under the high temperature of the flame. This process can absorb the heat of the flame. At the same time, the produced potassium strontium ion aerosol can combine with the active oxygen atoms near the flame, thereby ensuring that the fire extinguishing stick has a higher fire extinguishing efficiency.

[0041] Specifically, the blade 60 and the window breaking hammer 70 can be made of alloy steel, carbon steel and stainless steel to ensure structural strength.

[0042] In application, when a general accident occurs in a car and a fire occurs in the car, the user can hold the handle 10 to remove the bottom cover 30, then aim the nozzle 201 at the fire source and pull out the pull ring 41 to make the spray cartridge 20 spray the agent toward the fire source to extinguish the fire.

[0043] In application, when a general accident occurs in the car and the door cannot be opened and the seat belt latch cannot be pulled out, the user can first use the blade 60 to cut the seat belt, and then use the window breaker 70 to break the window to get out of the car.

[0044] In application, when a serious car accident occurs, resulting in a fire in the car, the door cannot be opened, and the seat belt latch cannot be pulled out, the user can use the blade 60 and the window breaker 70 to leave the car, and use the handle 10 and the spray cartridge 20 to extinguish the fire in time.

[0045] In one embodiment, please refer to Figures 2 to 4 The support member 50 includes a first support portion 51 and a second support portion 52 that are bent and connected to each other.

A first slot 501 is provided on the surface of the second support portion 52 facing away from the bottom cover 30 for plugging in the window breaking hammer 70.

[0046] In use, the first support portion 51 and the second support portion 52 are integrally formed, and the blade 60 and the window breaker hammer 70 are integrated into the bottom cover 30 through the first support portion 51 and the second support portion 52, occupying less space, making the fire extinguisher more convenient to carry.

[0047] In one embodiment, please refer to Figures 2 to 4 The first support portion 51 and the second support portion 52 have a second slot 502 on their surfaces facing the bottom cover 30 , and the outer wall of the bottom cover 30 has a third slot 302 corresponding to the second slot 502 .

[0052] In application, the zigzag slide groove 303 extends in a zigzag shape, the shape of the protrusion 103 is adapted to the zigzag slide groove 303, and the number of the zigzag slide groove 303 and the number of the protrusion 103 are both multiple, so as to make the connection between the handle 10 and the bottom cover 30 more stable.

[0053] Specifically, when installing the bottom cover 30 on the second end 12, first insert the protrusion 103 into one end of the zigzag groove 303, and then push the bottom cover 30 in a straight line until the protrusion 103 reaches the corner of the zigzag groove 303, and then twist the bottom cover 30 until the protrusion 103 reaches the other end of the zigzag groove 303, and the installation between the bottom cover 30 and the handle 10 is completed.

[0054] Specifically, when removing the bottom cover 30 from the second end 12, first twist the bottom cover 30 until the protrusion 103 reaches the corner of the zigzag groove 303, and then pull the bottom cover 30 in a straight line until the protrusion 103 disengages from the zigzag groove 303, thereby completing the disassembly between the bottom cover 30 and the handle 10.

[0055] In one embodiment, please refer to Figures 2 to 4 A retaining ring 13 is provided on the outer peripheral wall of the first end 11 adjacent to the second end 12 .

[0056] In application, by providing the retaining ring 13 , when the fire extinguishing rod is used to extinguish a fire, the palm of the user holding the handle 10 can be prevented from touching the spray cartridge 20 .
