Description

Sleep nursing earmuff Technical Field The invention relates to the technical field of sleep assistance, in particular to a sleep nursing earmuff. Background The sleeping earmuff is particularly suitable for people sensitive to noise or noisy in sleeping environment, external interference is reduced through physical sound insulation, relatively quiet sleeping environment is created, actual effects are different from person to person, personal comfort is needed to be combined, comprehensive judgment is needed for use habit, the general earmuff can be divided into an integral type and a split type, the integral type can be used for wrapping and sound insulation on two ears at the same time, the split type can be used for wrapping single-side ears independently, the sleeping earmuff can be selected as required, the action principle of the sleeping earmuff is that most earmuffs are made of sound insulation materials (such as memory cotton and sponge) for wrapping the ears, noise is reduced through blocking or absorbing sound waves, the noise reduction capability is generally 20-30 dB, and part of low-frequency noise can be filtered. The existing split earmuff is directly fixed on the outer outline of the ear during use, and the ear of a user is wrapped and locked by means of integral elasticity (such as elastic fiber materials in textiles), so that the problem of loosening due to actions such as turning over of the user during sleeping is prevented, but the situation of uneven stress is easily generated due to inconsistent upper and lower widths and shapes of the ear of a human body during integral wrapping, obvious discomfort of the ear is easily caused due to uneven stress of the ear for a long time, the sleeping condition of the user is influenced instead, and brittle fracture of the soft tissue structure of the ear is possibly caused during severe. Disclosure of Invention In order to overcome the defects in the prior art, the embodiment of the invention provides a sleep nursing earmuff, which forms double-layer fixing measures of external wrapping and internal supporting on the ear of a user by arranging an arc-shaped tightening ring and a flexible supporting plate, so that the wrapping effect is effectively improved on one hand, falling off caused by posture adjustment of the user is prevented, the whole stress of the ear is ensured to be uniform on the other hand, and the comfort level of a patient is ensured, so that the problems in the background art are solved. In order to achieve the above purpose, the invention provides the technical scheme that the sleep care earmuff comprises an earmuff body with an oval structure, wherein an arc-shaped tightening ring is fixedly arranged at the outer side edge of the earmuff body, the whole arc-shaped tightening ring is bent towards the inside of the earmuff body, a flexible supporting plate is fixedly arranged in the earmuff body and comprises a base, the edge of the base is provided with an arc track, the concave direction of the arc track points to the central axis of the base, an arc-shaped surface is integrally formed at the outer side of the base, the arc-shaped surface protrudes towards the outer side of the earmuff body, the highest point of the protrusion is positioned in the wrapping range of the arc-shaped tightening ring, a flexible plate is fixedly connected to the side surface of the arc-shaped surface and is positioned at the joint of the arc-shaped track, the end part of the flexible plate is provided with a round end, the whole volume of the flexible plate is gradually increased from the root to one side of the round end in equal proportion, and the flexible plate and the inner wall of the earmuff body is distributed at intervals.
