Description

Portable water mist fire extinguisher spray device

This creation is about an atomizing device for a portable fire extinguisher, especially a device that can guide pressurized fluid to the device for diversion, rotation, and atomization, and produce fine water mist, which can save water and extend The radiation time effectively eliminates the effect of the fire extinguishing source.

Traditional portable fire extinguishers can be divided into four types: sea dragon, carbon dioxide (CO2), dry powder and foam fire extinguishers. The structure is roughly composed of a bottle, a valve, a pipe and a nozzle. The sea dragon, Different extinguishing agents such as carbon dioxide (CO2), dry powder or foam. The aforementioned four types of fire extinguishing agents, in addition to sea dragons and carbon dioxide gas that naturally discharge the atmosphere, dry powder and foam fire extinguishers all pollute the environment, and it is difficult to deal with the aftermath of the fire. The former two have a considerable impact on the atmospheric environment.

For the nozzle structure of the portable fire extinguisher, it is assembled at one end of the pipe, and the fire extinguishing agent is miniaturized through several perforations of the nozzle, and appropriate pressure is applied to make the fire extinguishing agent spray out; this can spray a long distance and make The fire extinguishing agent produces better coverage and achieves a better fire extinguishing effect.

The nozzle technology of conventional portable fire extinguishers, such as the "water mist fire extinguisher" disclosed in the domestic invention patent No. 093139639, includes: bottle body, valve body, air injection device, air safety release device, handle device and nozzle. The feature is that the above-mentioned grave tube has a pipe and a water mist nozzle, the front end of the water mist nozzle has a plurality of arc grooves, and each of the arc grooves has A nozzle, and the rear end of the water mist nozzle has a flange, the flange forms a notch, the notch is connected to the pipe, and the notch corresponds to the arc groove and also has a plurality of grooves, the The grooves each have a guide port, and the guide port is connected to the nozzle, by injecting air into the bottle body filled with water through the air injection device, and then by passing the compressed water in the bottle body through After being released, it enters the nozzle through the pipe to produce a multi-layer fan spray.

Another sprinkler technology for conventional portable fire extinguishers, such as the "Improved Structure of Fire Extinguisher Sprinkler" disclosed in the domestic invention patent No. 095205410, includes: a sprinkler with an outlet on its top edge surface and a periphery adjacent to the top There are circumferentially spaced side outlets, and the bottom edge is provided with threads; a cover is roughly horn-shaped for locking with the spray head; a pipe body, one end of which is connected to the spray head, and the other end is provided with a joint , To be locked to the spout of the fire extinguisher; by the combination of the aforementioned components, when the fire extinguisher is spraying the fire extinguishing agent, the outlet and the side outlet of the sprinkler and the cover body can make the fire extinguishing agent sprayed. A wider range of spraying can improve the fire extinguishing effect.

Since the conventional water mist nozzle of the first case mentioned above uses only micropores to atomize the fluid, a relatively large fluid pressure is required for atomization, and the atomization effect is not good, which also results in shortened operation time of the fire extinguisher and reduced fire extinguishing efficiency. decline. The aforementioned second case of the prior art uses a nozzle and a horn-shaped cover provided outside the nozzle to allow the fire extinguishing agent to flow through the cover to naturally produce a pressurized effect and spray with an expanded range.

On the other hand, the release time of the conventional portable fire extinguisher is about 10 to 20 seconds, and the protection time is too short. If the fire source cannot be extinguished instantly, the fire cannot be controlled. Therefore, the author of this case proposes a fluid that can effectively atomize the fluid, which can produce better fire extinguishing effects with less water and also effectively extend the operating time of the fire extinguisher.

In view of this, the portable water mist fire extinguisher spray device disclosed by this creation includes: A sprinkler connected to the pressurized water source of the fire extinguisher, forming a space inside with a plurality of micro-holes at the front end; a spoiler, which is arranged in the space and can be rotated in the space to divert the fluid in the sprinkler , Pressurized, rotated, and impacted and sent to the micro-holes at the front end of the nozzle; with the above components, the spoiler can be used to rotate in the space to atomize the fluid of the fire extinguishing agent to produce spray, while saving water, Extend the radiation time, effectively eliminate the fire source and other functions.

The main purpose of this creation is to provide a portable water mist fire extinguisher spray device, which has a specially designed flow channel, spoiler and micro-hole sprinkler. This spray device is connected to the portable water mist fire extinguisher. The provided pressurized water flows through the atomization device of this creation, and the specially designed flow channel produces fine water mist spray, which can save water consumption, extend the radiation time, and effectively eliminate the fire extinguishing source.

The second purpose of this creation is to provide a portable water mist fire extinguisher spray device, which uses a spoiler to guide the fluid to rotate in the direction of the pipe wall and down into the multiple micro holes of the nozzle, using pressure, rotation, impact and micro holes And other mechanisms, effectively atomize the fluid of the fire extinguishing agent.
