Huawei has applied for a new patent for dust and water resistance: the performance may be stronger than IP68
Recently, Huawei has made further breakthroughs in the dustproof, waterproof and breathable performance of terminal equipment.
An application dated on May 1, with the publication number CN111092973A, was exposed by the media mainly for a patent for dustproof, waterproof and breathable on terminal equipment.
The full description of the patent is as follows:
The present application relates to the technical field of Electronic products, and in particular, to a mobile terminal. The mobile terminal includes a casing, the casing is formed with a first opening, and a waterproof and breathable membrane assembly is provided in the casing corresponding to the first opening. The waterproof and breathable membrane assembly A dust-proof net is arranged on the side facing the casing, and a first layer of adhesive layer is used for bonding the dust-proof net and the casing.
A second opening is formed at the position of the first adhesive layer corresponding to the first opening, so that the inside of the housing communicates with the outside through the waterproof and breathable membrane assembly, the dustproof net, the second opening and the first opening in sequence.
In the mobile terminal provided by the present application, by setting the dustproof net, when the outside air enters the mobile terminal, the dust particles and other dirt from the outside are isolated by the dustproof net, which effectively prevents the dirt from adhering to the waterproof and breathable membrane assembly, resulting in The ventilation failure of the waterproof and breathable membrane assembly ensures the stability of the use of the waterproof and breathable membrane assembly, and also ensures that the mobile terminal can stably communicate with the external air pressure.
At present, Huawei already has the world’s highest waterproof level of IP68. The new patent applied for this time will likely make the waterproof and dustproof functions of Huawei’s terminal equipment more powerful and more diverse.
