Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides a dry powder fire extinguishing device based on the principle of fluid pressure, which has the advantages of automatically stirring the powder and maintaining constant pressure, and solves the problem that the existing dry powder fire extinguisher has dry powder and The compressed gas inside the fire extinguisher is separated, so it must be artificially shaken to mix the dry powder with the compressed gas when using it. At the same time, the pressure of the compressed gas inside the fire extinguisher cannot maintain a constant pressure during the fire extinguishing process, so that the dry powder fire extinguishing agent can be used to extinguish the fire. The range of agent spraying will be reduced, which will greatly reduce the problem of fire extinguishing effect

The invention relates to the technical field of pressurization, and discloses a dry powder fire extinguishing device based on the principle of fluid pressure. A stirring fan is connected, the inside of the bottle body is movably connected with a pressure plate, the inside of the bottle body is fixedly connected with a closure cover, and the outside of the closure cover is fixedly connected with an elastic membrane; , Spring 1, collision block, gear 1, gear 2, moving block 1, gear 3, moving block 2, slide plate, detection component, slide rail, and slider interact with each other, allowing users to use the fire extinguisher in the process of Under the action of the pressure plate, the internal pressure of the fire extinguisher is always maintained at a constant pressure, so that the fire extinguishing range of the fire extinguisher can always be kept in a better spraying range and the fire extinguishing time can be shortened.
Description
technical field [0001] The invention relates to the technical field of pressurization, in particular to a dry powder fire extinguishing device based on the principle of fluid pressure. Background technique [0002] Dry powder fire extinguishers are widely used in people's daily life. Dry powder fire extinguishers are widely loved by people for their unique characteristics of convenient use, wide fire extinguishing range and good fire extinguishing effect. For people living in cities, fire prevention is very important. , dry powder fire extinguishers have become a must-have fire prevention artifact for people at home, but the existing dry powder fire extinguishers have the separation of the dry powder and the compressed gas inside the fire extinguisher after being placed for a period of time during use, so it must be artificially shaken to mix the dry powder with the compressed gas when in use, and at the same time The pressure of the compressed gas inside the fire extinguish...
