Problems solved by technology

Existing masks are generally made of gauze or filter sponge. In order to improve the filtering effect, it is necessary to use multi-layer or thicker gauze or sponge. Therefore, when the air passes through the filter layer, the resistance is large and there is a shortcoming of difficulty in breathing; and When a single-layer or thinner mask is used, there are disadvantages of insufficient filtration and poor filtering effect

Embodiment 1

[0027] like figure 2 , image 3 As shown, in the present embodiment, the fractal channel filter device 6 is connected together by the total air intake pipe 7 and the three-stage fractal channel filter unit 4 in a gradually branching and expanding manner, and each stage of the fractal channel filter unit 4 It includes a main pipe 11 and a branch pipe 12 , and the main pipe 11 and the branch pipe 12 are vertically connected to form a T-shaped filter unit 21 . The total intake pipe 7, the main pipe 11, and the branch pipe 12 are all hollow pipes, which can be made of plastics, rubber, silica gel, metal, cotton cloth, adsorption materials, or other materials. Injection moulding, gluing, inlaying, screwing or integral manufacturing.

[0028] The end of the total intake pipe 7 is connected in parallel with two first-stage T-type filter units 8, and two second-stage T-type filter units 9 are connected in parallel at both ends of each first-stage T-type filter unit 8, and each firs...

Embodiment 2

[0033] like Figure 4 As shown, in this embodiment, the fractal channel filter device 6 includes three-stage Y-type filter units, which are respectively the first-stage Y-type filter unit 16, the second-stage Y-type filter unit 17, and the third-stage Y-type filter unit. The filter unit 18 and the three-stage Y-shaped filter unit are connected together in a way of gradually branching and expanding. Each stage of the fractal channel filter unit 4 includes a main pipe 11 and two branch pipes 12, and the two branch pipes 12 are obliquely installed on the main pipe 11 to form a Y-shaped filter unit. The two branch pipes 12 of the first-stage Y-shaped filter unit 16 are respectively connected with two second-stage Y-shaped filter units 17, and the two branch pipes 12 of one second-stage Y-shaped filter unit 17 are respectively connected with three third-stage Y-shaped filter units. Three-stage Y-type filter unit 18, a branch pipe 12 in the second-stage Y-type filter unit 17 is con...

Embodiment 3

[0037] like Figure 5 As shown, in this embodiment, the fractal channel filter device 6 includes a main air intake pipe 7 , an air intake hollow disk 19 and six fractal channel filter units 4 . The total air intake pipe 7 communicates with the air intake hollow disk 19, and the air intake hollow disk 19 communicates with six fractal channel filter units 4 evenly distributed around it.

[0038]The six fractal channel filter units 4 have the same structure, and each fractal channel filter unit 4 is composed of a T-shaped filter unit 20 and two stages of H-shaped filter units. The two-stage H-type filter units are respectively a first-stage H-type filter unit 21 and a second-stage H-type filter unit 22 . The T-shaped filter unit 20 includes a main pipe 11 and a branch pipe 12, the main pipe 11 and the branch pipe 12 are vertically connected, and the shape is T-shaped. The H-shaped filter unit includes a main pipe 11 and two branch pipes 12, and two ends of the main pipe 11 are ...

Abstract

The invention relates to a split channel type filtering mask. The split channel type filtering mask is characterized in that a split channel type filtering device is arranged in the mask and composed of a plurality of split channel type filtering units, and the split channel type filtering units are connected in a series or parallel manner. According to the split channel type filtering mask, the inertia adsorption type dust removing method is adopted, the unique split channel type filtering structure is adopted, and therefore the problems that according to an existing mask, breathing is not smooth, resistance is large and stuffiness is caused are solved.

Description

technical field [0001] The invention relates to a filter device, in particular to a fractal channel type filter mask. Background technique [0002] People often use masks in places where there is dust or where dust protection is required, or in weather with "smog". Existing masks are generally made of gauze or filter sponge. In order to improve the filtering effect, it is necessary to use multi-layer or thicker gauze or sponge. Therefore, when the air passes through the filter layer, the resistance is large and there is a shortcoming of difficulty in breathing; and When a single-layer or thinner mask is used, there are disadvantages of insufficient filtration and poor filtering effect. Contents of the invention [0003] The purpose of the present invention is to provide a kind of fractal channel filter mask in order to overcome the deficiencies in the prior art. [0004] In order to solve the problems of the technologies described above, the present invention adopts the ...
