Embodiment 1

[0025] Embodiment 1: as figure 1 , figure 2 As shown, a filter device on a filtering respirator includes a circular tank body 1 and a circular cover 2, the tank body 1 and the cover 2 are made of flame-retardant plastic material, and the tank body 1 and the cover 2 are provided with Phosphor coating. Both the tank body 1 and the cover 2 are provided with ventilation holes 3 , and the tank body 1 is provided with a filter layer 4 . There are 24 first supporting ribs 5 radially arranged on the inner side of the bottom of the tank body 1 , the top of the tank body 1 is an opening, and the first supporting ribs 5 on the tank body 1 are equally spaced. There are 24 second supporting ribs 6 on the inner side of the cover 2 in the radial direction, and the second supporting ribs 6 on the cover 2 are equally spaced. A flange 7 protrudes from the cover 2, and the cover 2 is nested into the opening of the tank body 1. The bottom of the tank body 1 is a convex round head, and the ve...

Embodiment 2

[0027] Embodiment 2: The difference from Embodiment 1 is that the cap 2 is screwed to the opening of the tank body 1, and the ratio of aloe vera gel and sodium carbonate in the coating 42 is 8:2.

Embodiment 3

[0028] Embodiment 3: The difference from Embodiment 1 is that the lid 2 and the opening of the tank body 1 are tightly and fixedly connected, and the ratio of aloe vera gel and sodium carbonate in the coating 42 is 7:3.

Abstract

The invention discloses a filtering device on a filtering respirator, which comprises a circular tank body and a circular cover, both of which are provided with ventilation holes, and a filter layer is provided in the tank body, and the bottom of the tank body is There are several first supporting ribs arranged radially on the inner side of the lid, the top of the tank body is an opening, and several second supporting ribs are arranged radially on the inner side of the lid. The middle of the filter layer is an adsorption layer of activated carbon, and there is an alkaline coating of aloe gel on both sides of the adsorption layer. The invention allows the air to enter the tank from the vent hole, and spreads over the entire filter layer plane along the channels between the first support ribs or the second support ribs, increasing the contact space between the internal medicine and the external air, and making the gas exchange smoother.

Description

technical field [0001] The invention relates to a filtering respirator for fire protection, in particular to a filtering device on the filtering respirator. Background technique [0002] Be prepared for danger in times of peace. In today's increasingly urbanized environment, it is essential to configure some fire-fighting self-rescue equipment in buildings and residences. When a fire breaks out, the quality and function of the fire-fighting self-rescue equipment directly affect the survival rate of personnel. Filter-type self-rescue respirator is more commonly used among many self-rescue equipment, which can isolate most of the smoke and poisonous gas to a certain extent. However, the filtering device of the existing filtering respirator generally fixes a filter plate with holes respectively on both sides of the filter layer containing medicines, as the gas channel, which has the following problems. The gas channel area of ​​the respirator is small, so that the gas exchang...
