Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, and in particular to a handheld water-based fire extinguisher. Background Technology

[0002] Water-based fire extinguishers are small fire-fighting devices that use water as the primary extinguishing medium and are characterized by being environmentally friendly, safe, and easy to operate. They are named for their compact size and ease of use with one or two hands. They extinguish fires through physical and chemical action and are suitable for various initial fire scenarios, especially for emergency protection in homes, offices, and vehicles.

[0003] In existing technologies, the extinguishing bottles are usually cylindrical or flat, about 20-30 cm high and 8-12 cm in diameter, with a single bottle weighing 1-3 kg. Adults can easily hold or carry them with one hand. However, when some devices do not have a support frame, the user needs to use their arm strength to hold the extinguishing bottle throughout the process. Especially when operating for a long time or when the extinguishing bottle has a large capacity, the arm is prone to fatigue, resulting in an unstable grip, loss of control over the spray direction, and affecting the fire extinguishing efficiency. Utility Model Content

[0004] The purpose of this invention is to suspend and support the fire extinguishing bottle so that the user does not need to lift the fire extinguishing bottle with arm strength, making it easier to use. It provides a handheld water-based fire extinguisher, which solves the problem that traditional handheld fire extinguishers require one hand to hold the bottle and the other to lift the handle. If there is no support, it is difficult to control the bottle stably with one hand, which may lead to interruption of spraying or waste of extinguishing agent.

[0005] This utility model also provides a handheld water-based fire extinguisher, including a tank, a fixed block rotatably connected to the bottom of the tank, a second rotating shaft rotatably connected to the bottom of the fixed block, a first support rod rotatably connected to the outside of the second rotating shaft, a first slider slidably connected to the outside of the first support rod, a first ball rotatably connected to the inside of the first slider, a connecting rod rotatably connected to the outside of the first ball, a second ball rotatably connected to one end of the connecting rod, a second slider rotatably connected to the outside of the second ball, and an electric push rod fixedly connected to the outside of the second slider.

[0006] According to the present invention, a handheld water-based fire extinguisher has a second support rod fixedly connected to the outside of the electric push rod, and the top of the second support rod is fixedly connected to the bottom of the tank.

[0007] According to the present invention, a handheld water-based fire extinguisher has a support plate fixedly connected to the bottom of the first support rod, a plurality of first springs fixedly connected to the bottom of the support plate, and a base plate fixedly connected to the bottom of the first springs.

[0008] According to the present invention, a handheld water-based fire extinguisher has a collar fixedly connected to the outside of the tank, and a limit block is fixedly connected to the outside of the collar.

[0009] According to the present invention, a handheld water-based fire extinguisher is provided inside the limiting block, and a support column is fixedly connected to one end of the water inlet pipe.

[0010] According to the present invention, a handheld water-based fire extinguisher is provided with a canister cap on the top of the canister body, and the top of the canister cap is fixedly connected to the bottom of the support column.

[0011] According to the present invention, a handheld water-based fire extinguisher is provided, wherein a first rotating shaft is rotatably connected inside the support column, a rotating block is rotatably connected outside the first rotating shaft, and a handle is fixedly connected outside the rotating block.

[0012] According to the present invention, a handheld water-based fire extinguisher has a threaded rod threaded to one end of the water inlet pipe, a housing fixedly connected to the bottom of the threaded rod, a first filter plate slidably connected inside the housing, a telescopic rod fixedly connected to the bottom of the first filter plate, a sliding block slidably connected inside the telescopic rod, a blade rotatably connected to the outside of the telescopic rod, a second filter plate slidably connected inside the housing, two second springs fixedly connected to the bottom of the second filter plate, a third filter plate fixedly connected to the bottom of the second springs, and a fourth filter plate fixedly connected inside the housing. Beneficial effects

[0013] 1. The handheld water-based fire extinguisher of this technical solution, driven by an electric push rod at the bottom of the tank, moves a second slider at one end onto a second support rod. The second slider causes the second ball inside to rotate, which in turn moves an external connecting rod. The connecting rod then causes a first ball at one end to rotate, which in turn moves the first slider on the first support rod. This causes the first support rod to move towards the center under the action of a second rotating shaft, bringing the bottom plate of the extinguisher into contact with the ground and supporting the tank. This suspends and supports the fire extinguisher, eliminating the need for the user to lift the extinguisher with their arm strength, making it more effortless to use.

[0014] 2. When water is introduced into the outer shell through the inlet pipe by pressing the handle, the resulting impact causes the telescopic rod inside the shell to compress, which in turn drives the external blades to rotate and pulverize some particles in the water. Then, the water is sprayed outward through the fourth filter plate at the bottom, forming a mist. This pulverization allows the extinguishing agent to mix more evenly, avoiding uneven concentration during spraying due to particle sedimentation. This ensures more comprehensive coverage and more stable cooling or oxygen isolation effects during fire extinguishing. Attached Figure Description

[0023] Reference Figure 1-4 This utility model embodiment of a handheld water-based fire extinguisher includes a tank 1, a fixed block 11 rotatably connected to the bottom of the tank 1, a second rotating shaft 12 rotatably connected to the bottom of the fixed block 11, a first support rod 13 rotatably connected to the outside of the second rotating shaft 12, a first slider 14 slidably connected to the outside of the first support rod 13, a first ball 18 rotatably connected to the inside of the first slider 14, a connecting rod 19 rotatably connected to the outside of the first ball 18, a second ball 20 rotatably connected to one end of the connecting rod 19, a second slider 21 rotatably connected to the outside of the second ball 20, and an electric push rod 23 fixedly connected to the outside of the second slider 21.

[0024] Specifically, driven by the electric push rod 23, the second slider 21 at one end moves on the second support rod 22. The second slider 21 drives the second ball 20 inside to rotate, thereby the second ball 20 drives the external connecting rod 19 to move. The connecting rod 19 drives the first ball 18 at one end to rotate, so that the first ball 18 drives the first slider 14 outside to move on the first support rod 13, so that the first support rod 13 moves towards the middle under the action of the second rotating shaft 12.

[0025] The electric push rod 23 is externally fixedly connected to a second support rod 22, and the top of the second support rod 22 is fixedly connected to the bottom of the tank body 1.

[0026] The electric push rod 23 is externally fixedly connected to a second support rod 22, and the top of the second support rod 22 is fixedly connected to the bottom of the tank body 1.

[0027] The tank body 1 is externally fixedly connected to a collar 8, and the collar 8 is externally fixedly connected to a limit block 9.

[0028] The limiting block 9 has an inlet pipe 7 inside, and one end of the inlet pipe 7 is fixedly connected to a support column 3.

[0029] Specifically, by pressing the handle 6, water from inside the tank 1 is introduced into the outer shell 24 through the inlet pipe 7.

[0030] The top of the tank body 1 is provided with a tank cover 2, and the top of the tank cover 2 is fixedly connected to the bottom of the support column 3.

[0031] The support column 3 is internally rotatably connected to a first rotating shaft 4, the first rotating shaft 4 is externally rotatably connected to a rotating block 5, and the rotating block 5 is externally fixedly connected to a handle 6.

[0032] One end of the water inlet pipe 7 is threadedly connected to a threaded rod 10. The bottom of the threaded rod 10 is fixedly connected to a housing 24. The inside of the housing 24 is slidably connected to a first filter plate 25. The bottom of the first filter plate 25 is fixedly connected to a telescopic rod 26. The inside of the telescopic rod 26 is slidably connected to a sliding block 27. The outside of the telescopic rod 26 is rotatably connected to a blade 28. The inside of the housing 24 is slidably connected to a second filter plate 29. The bottom of the second filter plate 29 is fixedly connected to two second springs 30. The bottom of the second springs 30 is fixedly connected to a third filter plate 31. The inside of the housing 24 is fixedly connected to a fourth filter plate 32.

[0033] Specifically, when water enters the interior of the outer casing 24 through the inlet pipe 7, the resulting impact force causes the telescopic rod 26 inside the outer casing 24 to compress, thereby driving the external blade 28 to rotate and crush some particles in the water. Then, the water is sprayed outward along the fourth filter plate 32 at the bottom, forming a mist.

[0034] Working principle: Driven by an electric push rod 23, the second slider 21 at one end of the bottom of the tank 1 moves on the second support rod 22. The second slider 21 drives the second ball 20 inside to rotate, which in turn drives the connecting rod 19 outside to move. The connecting rod 19 drives the first ball 18 at one end to rotate, causing the first ball 18 to drive the first slider 14 outside to move on the first support rod 13. Under the action of the second rotating shaft 12, the first support rod 13 moves towards the center, bringing the bottom plate 17 of the tank 1 into contact with the ground and supporting the tank 1. This suspends and supports the fire extinguisher bottle. Users do not need to lift the fire extinguisher bottle with their arm strength, making it easier to use. When the water inside the canister 1 enters the outer shell 24 through the inlet pipe 7 by pressing the handle 6, the resulting impact causes the telescopic rod 26 inside the outer shell 24 to squeeze. This causes the telescopic rod 26 to drive the external blade 28 to rotate, pulverizing some particles in the water. Then, the particles are sprayed outward along the fourth filter plate 32 at the bottom, forming a mist. This pulverization allows the extinguishing agent to be mixed more evenly, avoiding uneven concentration during spraying due to particle sedimentation. This ensures more comprehensive coverage and more stable cooling or oxygen isolation effects during fire extinguishing.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
