Embodiment 2
[0029] Embodiment two, the difference with embodiment one is:
[0030] see image 3 , The casing 1 is provided with an avoidance groove 15 . The escape groove 15 extends along the circumference of the housing 1 . The central angle corresponding to the avoidance groove 15 is 180°, that is, the extension length of the avoidance groove 15 is half of the circumference of the housing.
[0031] A drum 5 is also rotatably connected in the casing 1 . The two bottom walls of the drum 5 are composed of two filter plates 51, in other words, a number of filter holes are opened on the two bottom walls of the drum 5 to form two filter plates. Drum 5 is connected together by staving 5-1 and bung 5-2 and constitutes. The inner space of the drum 5 constitutes a filter material storage chamber 12 . A partition 55 is provided inside the drum 5 . The partition plate 55 evenly divides the filter material storage chamber 12 into a first branch storage chamber 121 and a second branch storage c...

The invention relates to a fire-fighting article, and provides a canister assembly for a fire-fighting self-rescue apparatus. The canister assembly for the fire-fighting self-rescue apparatus comprises a shell and two filter plates, wherein the shell is divided into an air cavity of an end close to the mouth, a filter material storage cavity and an air cavity of an end away from the mouth by the two filter plates; an air hole of the end close to the mouth is formed in the air cavity of the end close to the mouth; an air hole of the end away from the mouth is formed in the air cavity of the end away from the mouth; a plurality of supporting pins for supporting the filter plates are separately formed in the air cavity of the end close to the mouth and the air cavity of the end away from the mouth; the air hole of the end close to the mouth is provided with a hole cover; the hole cover comprises a cover plate and a top block which is connected to the cover plate; the cover plate and the shell are integrally formed together; a damaged guiding groove is formed in the position where the cover plate is connected with the shell; the damaged guiding groove is positioned in the inner side of the cover plate; and the top block is positioned on the outer side of the cover plate and is projected out of the shell. According to the canister assembly for the fire-fighting self-rescue apparatus, the hole cover cannot be loosened easily, the filter plates cannot deform easily, and the problems that a rubber plug which seals an air hole drops easily and filter plates which are hung in the air deform easily are solved.
Description
technical field [0001] The invention relates to fire-fighting supplies, in particular to a poison canister assembly of a fire-fighting self-rescue respirator. Background technique [0002] The fire-fighting self-seeking breathing apparatus is an appliance used to wear during fire-fighting operations to prevent smoke poisoning. The respirator filters the inhaled air through the green poison canister. The Chinese patent application number is 2012101089456, and the publication date is August 1, 2012. In the patent document, one existing canister for respirators is disclosed. The basic structure of the canister includes a shell and two filter plates located in the shell. The two filter plates divide the shell into an air cavity near the mouth, a filter material storage cavity and an air cavity at the far mouth. The air cavity near the mouth is equipped with The air hole near the mouth end and the air cavity at the far mouth end are provided with air holes at the far mouth end,...
