AI Technical Summary
Existing door bottom gap sealing products suffer from insufficient durability, poor adaptability, poor installation stability, and unsatisfactory dustproof and sound insulation effects. In particular, traditional rubber strips are prone to deformation, sponge strips are prone to mold, and simple brush strips are unstable to install and cumbersome to clean.
A soundproof and dustproof brush strip for door bottom gaps is designed. The base is fixed with screws, and the soundproof and dustproof mechanism, including the combination structure of the base, hook and panel, enhances the sealing and aesthetics. The brush body fits tightly into the gap, and the hook snaps together to achieve stable installation and convenient cleaning.
It effectively blocks dust and insects, reduces noise transmission, and improves indoor quietness and cleanliness. It is stable to install and easy to clean. The screw heads are covered by the panel for a neat appearance, and it enhances the sealing and durability of gaps.
