Abstract
The invention relates to the field of fire safety equipment, and in particular relates to a dry powder extinguisher. The dry powder extinguisher comprises a tank body and a fixed seat which is connected with the tank body in a sealing manner, wherein a combustion chamber which is communicated with the inner part of the tank body is further arranged on the fixed base; an ignition device is further connected with the combustion chamber; and a combustion powder column is arranged in the combustion chamber. The combustion chamber which is communicated with the inner part of the tank body is arranged on the fixed base, so the combustion powder column in the combustion chamber is ignited by the ignition device, and a lot of gasses are quickly generated through the combustion of the combustion powder column; the communication chamber is communicated with the inner part of the tank body, so the generated gases enter the inner part of the tank body from the combustion chamber. The size of the inside of the tank body is limited, so when the gas pressure in the tank body is higher than the atmospheric pressure, the dry powder stored in the tank body is pressed out from the tank body to reach the fire breakout position, thereby achieving the purpose of extinguishing. Thus, the dry powder extinguisher provided by the invention does not need to be stored under high pressure as the dry powder extinguisher in the prior art.
