Embodiment 1

[0031] Please refer to figure 1 , figure 1 Shown is that this embodiment provides a protective mask for filtering harmful gases, which includes a flexible protective cover main body 1, a filter 2 and a strap 3, and the flexible protective cover main body 1 is provided with a connecting portion 11 and a plurality of symmetrically distributed connections The buckle 12 , the connecting portion 11 is engaged with the filter 2 , and the connecting buckle 12 is connected with the strap 3 .

[0032] In some embodiments of the present invention, for the problem of poor sealing after the main body of the protective cover is connected to the face in the prior art, this embodiment adopts a flexible protective cover main body 1 that can be bonded, and the flexible protective cover 1 in its specific embodiment The material of the main body 1 is made of medical flexible silicone. Because the flexibility of the medical flexible silicone is good, it can be quickly fitted according to the dif...

Embodiment 2

[0034] Please refer to figure 1 , this embodiment is based on the technical solution proposed in Embodiment 1. The filter 2 includes a protective shell 21 and a filter element 23 , the protective shell 21 is clamped with the connecting portion 11 , and the filter element 23 is penetrated in the protective shell 21 and the connecting portion 11 .

[0035] In some embodiments of the present invention, when the user wears it, in order to allow the user to breathe normally, this embodiment uses the filter 2 to filter the external harmful gas. The specific implementation method is to use the filter element 23 to filter the harmful gas. Filtration, the protective shell 21 is set to connect with the connecting part 11, so that a limiting space is formed between the protective shell 21 and the connecting part 11, so as to achieve the purpose of limiting the filter element 23, and also play a role in protecting the filter element 23. The safety of the protective mask for filtering harm...

Embodiment 3

[0037] Please refer to figure 2 , this embodiment is based on the technical solution proposed in Embodiment 2, and also includes a limiting grid 4, the connecting part 11 is sleeved on the limiting grid 4, and the filter element 23 is arranged between the protective shell 21 and the limiting grid 4 .

[0038]In some embodiments of the present invention, when wearing a protective mask, the mouth or nose is likely to be in direct contact with the filter element 23, and because the protective mask needs to completely isolate the user's mouth and nose from the outside air, the user's mouth and nose may The nose is prone to sweat and oil in a closed environment. In this case, if there is direct contact with the filter element 23, sweat and oil stains on the user's face will inevitably be rubbed on the filter element 23, thereby causing the air vents on the surface of the filter element 23 to be blocked, and the user's breathing is restricted, resulting in a shortened service life...

Abstract

The invention provides a protective mask for filtering harmful gas, and relates to the technical field of protective masks. The protective mask comprises a flexible protective cover body used for being adsorbed or bonded to the skin, a filter and a bandage, a connecting part and a plurality of symmetrically-distributed connecting buckles are arranged on the flexible protective cover body, the connecting part is clamped with the filter, and the connecting buckles are connected with the bandage. According to the protective mask for filtering the harmful gas, the harmful gas can be effectively isolated, and the safety of a user is improved.

Description

technical field [0001] The invention relates to the technical field of protective masks, in particular to a protective mask for filtering harmful gases. Background technique [0002] As personal protective equipment, protective masks are used to provide effective protection for personnel's respiratory organs and facial skin. It is a component that isolates the personnel's face from the outside air. The protective mask for filtering harmful gases in the prior art is made up of a face mask, an air guide tube and a canister. The face mask can be directly connected with the canister, or connected with the canister with an air guide tube. Gas masks can choose various types of canisters according to the protection requirements, and are used in chemical, warehouse, scientific research, and various toxic and harmful working environments. However, in the prior art, the material of the protective mask and the face of the human body is relatively hard, so that when the user wears it,...
