Description

Technical Field

[0001] This utility model relates to a fire extinguishing device, and more particularly to a multifunctional portable handheld fire extinguisher structure. Background Technology

[0002] The extinguishing principles of known fire extinguisher technology are limited to the capacity of the cylinder container, resulting in insufficient capacity and poor extinguishing efficiency. Furthermore, using larger volumes of extinguishing agents poses a risk of explosion due to the excessively large cylinders and the immense pressure of the nitrogen gas.

[0003] It is known that existing traditional fire extinguisher technology is limited by issues with agent capacity and nitrogen pressure, and the high pressure of nitrogen makes it a hazardous material. For example, rusting of the fire extinguisher cylinder can lead to its explosion. In addition, existing traditional fire extinguisher gas-driven technology suffers from high-pressure nitrogen leakage due to rubber fatigue in the valve components, resulting in insufficient nitrogen gas, preventing gas-driven operation, and thus preventing the extinguishing agent from being sprayed to extinguish the fire.

[0004] Therefore, a driving method that does not require high-pressure nitrogen gas is needed to replace the small electric pump that can continuously spray fire extinguishing agents. Utility Model Content

[0005] In view of the above problems, the main purpose of this utility model is to provide a multifunctional portable handheld fire extinguisher structure, which is lightweight and portable, and uses a small electric pump to start via battery charging. It replaces bulky fixed large-capacity fire extinguishing agents and nitrogen fire extinguishing cylinders, and is not limited by wiring and pipeline constraints. It can spray fire extinguishing at will, and the electric pump spray pressure is greater than the traditional accumulator gas diversion pressure, so the sprayed fire extinguishing agent can exert a greater fire extinguishing effect.

[0061] Figure 4 This is a three-dimensional schematic diagram of the liquid inlet of the multifunctional portable handheld fire extinguisher structure of this utility model, showing a liquid bottle connected to the inlet. Figure 5 This is a three-dimensional schematic diagram of the liquid inlet of the multifunctional portable handheld fire extinguisher structure of this utility model, which is connected to a water pipe. Figure 6 This is a three-dimensional schematic diagram of the liquid outlet of the multifunctional portable handheld fire extinguisher structure of this utility model, which is connected to the nozzle. Figure 7 This is a three-dimensional schematic diagram of the liquid outlet of the multifunctional portable handheld fire extinguisher structure of this utility model, which is connected to a solution bottle with a nozzle.

[0062] Please refer to Figure 4 In some embodiments, the liquid inlet 710 is detachably connected to and communicates with a liquid bottle, such as a fire extinguishing agent bottle 711.

[0063] Please refer back to this page. Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 The multifunctional portable handheld fire extinguisher structure 10 of this utility model may further include a spray start button 800. The spray start button 800 may be disposed at the extension 120 of the housing 100 and may be electrically connected to the rechargeable battery 220, the control circuit board 300 and the drive motor 400. In some embodiments, the spray start button 800 may be a push-button switch, but is not limited thereto.

[0064] According to the above structure, when intending to extinguish a fire with water, the user (not shown) can hold the handle 200 and press the spray start button 800. At this time, the control circuit board 300 is electrically connected to the rechargeable battery 220 and is activated. The control circuit board 300 starts the drive motor 400 to rotate, which in turn drives the torque ratio gear set 500 to rotate and increase the rotation torque. The torque ratio gear set 500 then controls the electric pump 600 to operate to increase the pressure and flow rate. At this time, the electric pump 600 can draw water from, for example, a liquid bottle from a fire extinguishing agent bottle 711 through the liquid inlet 710. The water pipe 712 draws in extinguishing agent or water, and the drawn-in extinguishing agent or water is then pumped by the electric pump 600 through the outlet connection 720 and through the nozzle 721 or the nozzle solution bottle 722 nozzle 723 to form a fire extinguishing water jet, water jet or spray with increased water pressure and flow rate for fire extinguishing. If the nozzle solution bottle 722 is connected to the outlet connection 720, the extinguishing agent can be installed in the solution bottle 724. When the nozzle 723 sprays water, it can simultaneously draw out the extinguishing agent in the solution bottle 724, and the inlet connection 710 can be connected only to the water pipe 712, thereby achieving the effect of fire extinguishing.

[0065] In summary, the multifunctional portable handheld fire extinguisher structure 10 of this utility model is primarily lightweight and portable. It uses a small electric pump 600, which is powered by a battery (i.e., a rechargeable battery 220), to replace bulky fixed large-capacity fire extinguishing agents and nitrogen fire extinguishing cylinders. It is not limited by wiring and pipeline constraints, and can spray fire extinguishing agents at will. Furthermore, the spray pressure of the electric pump 600 is greater than that of traditional pressurized gas drainage, allowing the fire extinguishing agent to exert a more effective fire extinguishing effect.
