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 breather. The filtering device comprises a circular tank and a circular cover, wherein the tank and the cover are both provided with ventilating holes; a filtering layer is arranged in the tank; multiple first support edges are arranged in the radial direction of the inner side of the bottom of the tank; the top of the tank is an opening; and multiple second support edges are arranged in the radial direction of the inner side of the cover. An active carbon absorbing layer is arranged in the middle of the filtering layer; and aloe gel alkaline coating layers are respectively arranged at the two sides of the absorbing layer. After air enters the tank from the ventilating holes, the air is fully dispersed on the whole plane of the filtering layer along channels among the first support edges or the second support edges, so that the contact space between internal medicament and external air is increased, and the air exchange is more smooth.

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...
