Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation cotton, in particular to a dust-proof sound insulation cotton. Background Technique

[0002] The sound insulation cotton has good heat insulation and sound insulation effects, can reduce the transmission and reflection of sound, and improve the comfort of the indoor environment. The application environment of the sound insulation cotton is very wide, including but not limited to the inside of the car hood, the downpipe, the ceiling, the floor material in home decoration, and the walls and ceilings of specific rooms, etc.

[0003] When the common sound insulation cotton on the market is in use, due to the accumulation of dust on the outside after long-term use, the performance of the sound insulation cotton is affected, and it is not easy to clean if dust enters the sound insulation cotton. Therefore, a dust-proof sound insulation cotton is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dust-proof sound insulation cotton to solve the problems that the performance is affected by the accumulation of dust at the sound insulation cotton and it is not easy to clean.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A dust-proof sound insulation cotton, including a sound insulation cotton main body for sound insulation and heat insulation, a cellulose layer is fixedly connected below the sound insulation cotton main body, and a dust-proof cloth is closely attached to the bottom of the cellulose layer.

[0007] Preferably, the first magic tape is embedded at the edge of the dust-proof cloth, the second magic tape is embedded at the edge of the cellulose layer, and the first magic tape and the second magic tape are closely attached.

[0008] Preferably, a plurality of arc-shaped grooves are formed on one side of the dust-proof cloth, and elastic blocks are attached to the grooves formed in the dust-proof cloth.

[0009] Preferably, the elastic block is fixedly connected to the cellulose layer, and the elastic block is made of a rubber block.

[0010] Preferably, a mildew-proof coating layer is provided on the other side of the sound insulation cotton main body, and the sound insulation cotton main body is arranged between the cellulose layer and the mildew-proof coating layer.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the present utility model, through the provided sound insulation cotton main body and cellulose layer, the cellulose layer has good air permeability and dust-proof performance. Due to its dense fiber structure, it can effectively filter tiny particulate matter in the air. By setting a dust-proof cloth on one side of the cellulose layer, the dust-proof effect of the sound insulation cotton main body is further enhanced. The double-layer dust-proof materials are stacked, making it difficult for dust to enter the sound insulation cotton main body. By setting the first magic tape and the second magic tape, it is convenient to disassemble, clean or replace the dust-proof cloth after long-term use, preventing dust accumulation. By setting elastic blocks on the cellulose layer and grooves at the dust-proof cloth, the dust-proof cloth has a positioning effect during installation, and the elastic blocks are usually made of rubber. Rubber can increase friction, making the dust-proof cloth not easy to move after installation. By setting a mildew-proof paint layer on the other side of the sound insulation cotton main body, the whole has a mildew-proof effect. Brief Description of the Drawings

[0019] Please refer to Figure 1-2, the present utility model provides a technical solution:

[0020] A dust-proof and sound-insulating cotton, comprising a sound-insulating cotton main body 1 for sound insulation and heat insulation. A cellulose layer 2 is fixedly connected below the sound-insulating cotton main body 1, and a dust-proof cloth 3 is closely attached to the bottom of the cellulose layer 2. By setting the double-layer dust-proof materials to be stacked, it is not easy for dust to enter the sound-insulating cotton main body 1. By setting the detachable dust-proof cloth 3, it is convenient to disassemble, clean or replace the dust-proof cloth 3 after long-term use, preventing dust accumulation.

[0021] A first magic tape 4 is embedded at the edge of the dust-proof cloth 3, and a second magic tape 5 is embedded at the edge of the cellulose layer 2. The first magic tape 4 and the second magic tape 5 are closely attached, facilitating the disassembly of the dust-proof cloth 3; a plurality of arc-shaped grooves 7 are formed on one side of the dust-proof cloth 3, and an elastic block 6 is attached to the grooves 7 formed in the dust-proof cloth 3, enabling the dust-proof cloth 3 to have a positioning effect during installation; the elastic block 6 is fixedly connected to the cellulose layer 2, and the elastic block 6 is made of a rubber block, facilitating the installation of the dust-proof cloth 3; a mildew-proof coating layer 8 is provided on the other side of the sound-insulating cotton main body 1, and the sound-insulating cotton main body 1 is arranged between the cellulose layer 2 and the mildew-proof coating layer 8, making the whole sound-insulating cotton main body 1 have a mildew-proof effect.

[0022] Working process: When the dust-proof and sound-insulating cotton is in use, first place the sound-insulating cotton main body 1 in a suitable position, and then install it. Align the mildew-proof coating layer 8 with the outside of the installation object, so that the sound-insulating cotton main body 1 has a mildew-proof effect, and the dust-proof cloth 3 is exposed outside. When the dust-proof cloth 3 has been used for a long time and there is dust on its surface, the user can use a cleaning tool to wipe and clean its outside, or hold a corner of the dust-proof cloth 3 and directly tear it off. The first magic tape 4 at the dust-proof cloth 3 and the second magic tape 5 at the cellulose layer 2 are separated, and the elastic block 6 gradually moves away from the groove 7. After the whole dust-proof cloth 3 is removed, it can be cleaned or replaced. Then place the cleaned or new dust-proof cloth 3 on the outside of the cellulose layer 2, and then gradually approach the cellulose layer 2. The elastic block 6 enables it to have a positioning effect during installation. Then stick and fix the first magic tape 4 and the second magic tape 5 to effectively fix the dust-proof cloth 3. By setting the double-layer dust-proof materials to be stacked, it is not easy for dust to enter the sound-insulating cotton main body 1. By setting the detachable dust-proof cloth 3, it is convenient to disassemble, clean or replace the dust-proof cloth 3 after long-term use, preventing dust accumulation.
