Description

Technical Field

[0001] This utility model relates to the field of dustproof cloth, and in particular to a double-layer dustproof mesh cloth. Background Technology

[0002] Most existing dustproof mesh fabrics are single-layered and are commonly used for protection, filtration, or isolation of dust. They require good air permeability and dustproof performance. However, existing dustproof mesh fabrics often exhibit good air permeability but poor dustproof performance, only blocking large particles such as lint and hair, while being less effective at blocking fine dust or pollen. Therefore, in order to meet usage requirements, the structure of dustproof mesh fabrics needs to be improved. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a double-layer dustproof mesh fabric that achieves both dust and toxicity protection with better results, without compromising breathability, exhibiting good breathability, a reasonable structure, and ease of use.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A double-layer dustproof mesh fabric includes a first dustproof mesh fabric, activated carbon sheets, and a second dustproof fabric. The lower part of the first dustproof mesh fabric is connected to the activated carbon sheets, which contain activated carbon particles. The lower part of the activated carbon sheets is connected to the second dustproof fabric. The first dustproof mesh fabric, activated carbon sheets, and second dustproof fabric are arranged sequentially from top to bottom. The lower part of the first dustproof mesh fabric has a first fastening adhesive, and the upper part of the second dustproof fabric has a second fastening adhesive. The lower part of the first fastening adhesive is connected to the second fastening adhesive. The outer periphery of the first dustproof mesh fabric and the outer periphery of the second dustproof fabric are connected to protective connecting strips.

[0006] The protective connecting strip of this utility model has two positioning connecting grooves on its inner side. The positioning connecting grooves are symmetrically arranged. The inner side of the positioning connecting groove is connected to a first dustproof mesh cloth and the inner side of the positioning connecting groove is connected to a second dustproof cloth.

[0007] The dustproof mesh fabric of this utility model has multiple No. 1 positioning connection holes on its upper part, which are evenly distributed on the upper part of the dustproof mesh fabric. The activated carbon sheet has multiple No. 2 positioning connection holes on its upper part, which are evenly distributed on the upper part of the activated carbon sheet.

[0008] The second dustproof cloth of this utility model has multiple third positioning connection holes on its upper part. The third positioning connection holes are evenly distributed on the upper part of the second dustproof cloth. The first positioning connection hole, the second positioning connection hole, and the third positioning connection hole correspond to each other. The inner side of the first positioning connection hole is connected to the positioning connection nail, the inner side of the second positioning connection hole is connected to the positioning connection nail, and the inner side of the third positioning connection hole is connected to the positioning connection nail fixing pad. The lower part of the positioning connection nail passes through the first positioning connection hole, the second positioning connection hole, and the third positioning connection hole in sequence to connect to the positioning connection nail fixing pad. Beneficial effects

[0009] The first dustproof mesh of this utility model is used to block large particles of debris (such as flying fluff and hair); the second dustproof mesh has a fine mesh (possibly down to the micron level) to filter fine dust, pollen, or PM; the protective connecting strip is used to absorb odors and toxic gases, and the protective connecting strip is detachable.

[0010] This invention does not include a protective connecting strip, allowing for good air circulation and preventing stuffiness, making it suitable for long-term wear or use. It is lightweight and thin, easy to carry and install. Adding a protective connecting strip allows it to be used as a gas mask; it is easy to disassemble and use, and has a reasonable structure.

The lower part of the first dustproof mesh fabric 01 is connected to the activated carbon sheets 02, which contain activated carbon particles. The lower part of the activated carbon sheets 02 is connected to the second dustproof fabric 05. The first dustproof mesh fabric 01, activated carbon sheets 02, and second dustproof fabric 05 are arranged sequentially from top to bottom. The lower part of the first dustproof mesh fabric 01 has a first fastening adhesive 06, and the upper part of the second dustproof fabric 05 has a second fastening adhesive 07. The lower part of the first fastening adhesive 06 is connected to the second fastening adhesive 07. Adhesive 07, No. 1 dustproof mesh 01 is connected to protective connecting strip 03 on the outer perimeter, and No. 2 dustproof cloth 05 is also connected to protective connecting strip 03 on the outer perimeter. No. 1 dustproof mesh 01 is used to block large particles of debris (such as flying fluff and hair); No. 2 dustproof cloth 05 has a fine mesh (possibly down to the micron level) to filter fine dust, pollen, or PM2.5; protective connecting strip 03 is used to absorb odors and toxic gases. Protective connecting strip 03 is detachable, thus achieving both dustproof and toxic gas protection, with better dustproof and toxic gas protection effects without affecting breathability. It has good breathability, a reasonable structure, and is easy to use.

[0020] Example 2:

[0021] The protective connecting strip 03 of this utility model has two positioning connecting grooves 11 on its inner side. The positioning connecting grooves 11 are symmetrically arranged. The inner side of the positioning connecting groove 11 is connected to the first dustproof mesh cloth 01 and the inner side of the positioning connecting groove 11 is connected to the second dustproof cloth 05.
