The publication number of this technical patent is CN 111092973A, and the filing date is1May, which is mainly used for dust prevention, waterproof and ventilation of terminal equipment.
The full text of this patent is as follows:
The application relates to the technical field of electronic products, in particular to a mobile terminal, which comprises a shell, wherein the shell is provided with a first opening; A waterproof and breathable membrane component is arranged in the shell corresponding to the first opening; A dustproof net is arranged on one side of the waterproof and breathable membrane component facing the shell; The first adhesive layer is used for bonding the dust screen with the shell.
A second opening is formed at the position of the first adhesive layer corresponding to the first opening, so that the inside of the shell is communicated with the outside through the waterproof and breathable film assembly, the dustproof net, the second opening and the first opening in turn.
In the mobile terminal provided by the application, by arranging the dustproof net, when the outside air enters the mobile terminal, dirt such as dust particles and the like are isolated by the dustproof net, so that the dirt is effectively prevented from adhering to the waterproof and breathable membrane component, which leads to the ventilation failure of the waterproof and breathable membrane component, the use stability of the waterproof and breathable membrane component is ensured, and the mobile terminal can stably communicate with the outside air pressure.
At present, Huawei's high-end flagship mobile phones generally come standard with the highest ip68 waterproof and dustproof rating, which is the highest waterproof rating at present, and the new patent applied this time is likely to make Huawei's terminal equipment more powerful and diversified in waterproof and dustproof functions.
