Description

Technical Field

[0001] The utility model relates to the technical field of intelligent wearable devices, in particular to an intelligent eye mask. Background Art

[0002] In recent years, with the improvement of people's requirements for health and quality of life, intelligent eye masks, as intelligent wearable devices integrating multiple functions such as sleep monitoring and stress management, have received extensive attention. However, there are several technical defects in the existing intelligent eye mask products, which affect the user experience and limit their popularization speed in the market.

[0003] At present, some intelligent eye mask products on the market adopt the strategy of integrating the signal acquisition device into the forehead part of the eye mask, and the signal acquisition device is encapsulated by a hard plastic shell. This design not only increases the overall hardness of the eye mask and reduces the wearing comfort, but also makes the assembly complex and the cost increase during the production process because the signal acquisition device is fixedly connected to the eye mask body. In addition, since the eye mask body is inseparable from the signal acquisition device, it cannot be cleaned separately, reducing the maintenance convenience.

[0004] To solve the above problems, intelligent eye mask products with a split design of the eye mask body and the signal acquisition device have emerged on the market. Although such a design has improved the wearing experience and maintenance convenience to a certain extent, it has also brought new challenges - the contact stability between the signal acquisition device and the user's forehead is insufficient.
