Embodiment Construction

[0017] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] see figure 1 As shown, an inner cylinder of a fire extinguisher includes an upper cylinder 1 and a lower cylinder 2 arranged in the up-down direction, and the upper cylinder 1 is slidably sleeved on the outer wall of the lower cylinder 2 . Wherein, the upper cylinder 1 includes a spout portion 11 with a spout 111 at the top of the upper cylinder 1, a coolant sheet 14 disposed in the inner cavity of the upper cylinder 1, an upper sheet 13 positioned on the upper end surface of the coolant sheet 14, and a support on the upper surface of the upper cylinder 1. The elastic support member 12 between the top of the upper cylinder 1 and the upper sheet 13, the lower cylinder 2 includes a fire extinguishing agent column 21 arranged in the inner cavity of the lower cylinder 2, an explosion vent 22 opened on the side wall...

Abstract

The invention discloses an inner cylinder of a fire extinguisher, which comprises an upper cylinder and a lower cylinder. The upper cylinder is slidably sleeved on the outer wall of the lower cylinder. The agent sheet, the upper surface of the coolant sheet, the upper sheet and the elastic support supported between the top of the upper cylinder and the upper sheet, the lower cylinder includes a fire extinguishing agent column in the inner cavity, and an explosion vent on the side wall of the cylinder. The side wall of the upper cylinder is also provided with a shielding part that can be shielded from the explosion vent or away from the explosion vent, and the side wall of the lower cylinder is also provided with a chute extending in the vertical direction for the upper cylinder to slide. The inner cylinder also includes a sliding part, and the coolant sheet is located between the upper sheet and the sliding part. During transportation or use, the inner cylinder avoids the shaking of the coolant sheet and avoids direct contact with the fire extinguishing agent, which ensures the complete combustion chemical reaction of the fire extinguishing agent and stabilizes the quality and flow of the generated fire extinguishing aerosol. The fire extinguishing ability is consistent with the fire extinguishing effect.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to an inner cylinder of a fire extinguisher. Background technique [0002] Existing portable fire extinguishers, such as hand-held aerosol fire extinguishers, usually use an inner cylinder and a shell sleeved on the inner cylinder, and the inner cylinder is usually provided with fire extinguishing agent, coolant, and the front end of the coolant. Nozzle, during the fire extinguishing process, after the fire extinguishing agent is ignited, the hot aerosol gas generated by the combustion chemical reaction accumulates rapidly in the cylinder, and the pressure in the cylinder will rise sharply, thus generating a huge driving force, pushing the aerosol to the coolant Move in the direction of the nozzle, push the cylinder cover forward along the direction of the nozzle, because the fire extinguishing agent is in direct contact with the fire extinguishing agent, so that when the fi...
