Abstract
Description
Technical Field
[0001] This invention relates to the field of sleep aid technology, and more specifically, to a sleep care earmuff. Background Technology
[0002] Sleep earmuffs can help improve sleep quality, especially for people who are sensitive to noise or have a noisy sleep environment. They reduce external interference through physical sound insulation, creating a relatively quiet sleep environment. However, the actual effect varies from person to person and needs to be judged in combination with personal comfort and usage habits. Generally, earmuffs can be divided into one-piece and two-piece types. One-piece earmuffs can cover both ears at the same time to insulate against noise, while two-piece earmuffs can cover only one ear. You can choose either one according to your needs. The working principle of sleep earmuffs: Most earmuffs use sound-insulating materials (such as memory foam and sponge) to cover the ears, reducing noise by blocking or absorbing sound waves. The noise reduction ability is usually 20-30 decibels, and it can filter some low-frequency noise.
[0003] Existing split earmuffs, when in use, are directly fixed to the outer contour of the ear and rely on the overall elasticity (such as elastic fiber materials in textiles) to wrap and lock the user's ear, preventing it from coming loose during sleep due to the user's turning over or other movements. However, because the width and shape of the human ear are not uniform, uneven force is easily generated when the ear is wrapped. Over time, uneven force on the ear can easily cause obvious ear discomfort, which can affect the user's sleep. In severe cases, it may even cause the soft tissue structure of the ear to become brittle and break. Summary of the Invention
[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a sleep care earmuff. By setting an arc-shaped tightening ring and a flexible support plate, a double-layer fixation measure is formed for the user's ear, which provides external wrapping and internal support. On the one hand, it effectively improves the wrapping effect and prevents the ear from falling off due to the user's posture adjustment. On the other hand, it can ensure that the overall force on the ear is even and ensure the patient's comfort, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a sleep care earmuff, comprising an earmuff body with an oval structure, an arc-shaped tightening ring fixedly disposed on the outer edge of the earmuff body, the arc-shaped tightening ring being bent inwards towards the inside of the earmuff body, a flexible support plate fixedly installed inside the earmuff body, the flexible support plate comprising a base, an arc-shaped trajectory disposed on the edge of the base, the concave direction of the arc-shaped trajectory pointing towards the central axis of the base, an arc-shaped surface integrally formed on the outer side of the base, the arc-shaped surface protruding outwards towards the outer side of the earmuff body, and the highest point of the protrusion being within the coverage area of the arc-shaped tightening ring, a flexible plate fixedly connected to the side of the arc-shaped surface and at the connection point between the arc-shaped surface and the arc-shaped trajectory, the end of the flexible plate forming a circular end, the overall volume of the flexible plate gradually increasing proportionally from the root to one side of the circular end, and a spacing distribution between the flexible plate and the inner wall of the earmuff body.
[0006] In a preferred embodiment, the earmuff body is made entirely of elastic sound-absorbing material, the arc-shaped tightening ring is made entirely of elastic fabric material, and the end of the arc-shaped tightening ring is woven into a semi-circular transition structure.
[0007] In a preferred embodiment, the bottom end of the base is adapted to the arc shape of the inner wall of the earcup body, and both the base and the arc surface are made of sound-absorbing sponge material, and the surface of the arc surface is smooth.
[0008] In a preferred embodiment, the base and the arcuate surface together form a T-shaped structure, and the base is located at the center of the earcup body.
[0009] In a preferred embodiment, the side of the arc-shaped surface is arc-shaped, and the connection between the arc-shaped surface and the arc trajectory is rounded. The arc-shaped bending direction of the flexible plate points to the inner wall side of the earmuff body, and the entire flexible plate is made of rubber material.
[0010] In a preferred embodiment, the overall curvature formed by the circular end and the flexible plate is greater than the curvature of the inner wall of the earcup body, and the arc-shaped surface can be twisted and adjusted in any direction toward the inner wall of the earcup body via an arc trajectory on the surface of the base.
[0011] The technical effects and advantages of this invention are as follows: This invention utilizes an arc-shaped tightening ring and a flexible support plate. First, the user fastens and wraps the earmuff around their ear. The elasticity of the arc-shaped tightening ring secures the earmuff to the user's ear contour, thus firmly wrapping the earmuff around the ear. Once the earmuff is fully wrapped, the arc-shaped surface inside the earmuff conforms to the center of the user's inner ear contour. Simultaneously, the flexible plate on the side of the arc-shaped surface adheres closely to the inner edge of the patient's inner ear, continuously providing outward support. This works in conjunction with the earmuff and the arc-shaped tightening ring to ensure that after the earmuff and the arc-shaped tightening ring have completely wrapped the user's ear contour, the flexible plate provides simultaneous support to the ear from the inside of the ear contour. This creates a double-layer fixation measure of external wrapping and internal support for the user's ear. On the one hand, it effectively improves the wrapping effect, preventing the earmuff from slipping off due to changes in posture. On the other hand, it ensures even force distribution on the ear, avoiding discomfort and injury caused by uneven force distribution in certain areas of the ear tissue, thus guaranteeing patient comfort.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, those skilled in the art who have not made any innovative embodiments are all within the scope of protection of the present invention.
[0015] As attached Figure 1 To be continued Figure 5The sleep care earmuff shown includes an oval-shaped earmuff body 1. An arc-shaped tightening ring 2 is fixedly disposed on the outer edge of the earmuff body 1. The arc-shaped tightening ring 2 is curved inwards towards the earmuff body 1. A flexible support plate 3 is fixedly installed inside the earmuff body 1. The flexible support plate 3 includes a base 31. An arc-shaped track 32 is disposed on the edge of the base 31, with the concave direction of the arc-shaped track 32 pointing towards the central axis of the base 31. An arc-shaped surface 33 is integrally formed on the outer side of the base 31, protruding outwards towards the outer side of the earmuff body 1, with its highest point located within the coverage area of the arc-shaped tightening ring 2. A flexible plate 34 is fixedly connected to the side of the arc-shaped surface 33 and at the connection point between the arc-shaped surface 33 and the arc-shaped track 32. A circular end 35 is formed at the end of the flexible plate 34. The overall volume of the flexible plate 34 is from the root... The volume of the flexible plate 34 gradually increases proportionally from the circular end 35 to one side. There is a spacing distribution between the flexible plate 34 and the inner wall of the earmuff body 1. With the above arrangement, it can be ensured that when the flexible plate 34 fits the ear contour on the inside, its gradually increasing volume conforms to the ergonomic design of the human ear contour, effectively providing support for the inside of the user's ear. Furthermore, the overall curvature formed by the circular end 35 and the flexible plate 34 is greater than the curvature of the inner wall of the earmuff body 1, so that when the ear is wrapped, the soft tissue at the edge of the ear forms an inward snapping posture, further improving the fit between it and the earmuff body 1 and improving its stability during use. At the same time, the highest point of the arc surface 33 is located within the wrapping range of the arc tightening ring 2, thereby ensuring that the arc tightening ring 2 first elastically tightens and fixes the ear contour, and then the arc surface 33 fits and supports the center of the ear, improving the cooperation effect between the two.
[0016] The earmuff body 1 is made entirely of elastic sound-absorbing material, and the arc-shaped tightening ring 2 is made entirely of elastic fabric material. The end of the arc-shaped tightening ring 2 is woven into a semi-circular transition structure. The bottom end of the base 31 is adapted to the arc shape of the inner wall of the earmuff body 1. The base 31 and the arc-shaped surface 33 are both made of sound-absorbing sponge material. The surface of the arc-shaped surface 33 is smooth. The base 31 and the arc-shaped surface 33 form a T-shaped structure, and the base 31 is located at the center of the earmuff body 1. With the above settings, the arc-shaped tightening ring 2 uses a flexible tension effect to wrap and lock the ear, improving the user's fit and comfort. At the same time, since the base 31 and the arc-shaped surface 33 are both made of sound-absorbing sponge material, after the earmuff body 1 absorbs and isolates noise on the outside, the base 31 and the arc-shaped surface 33 can simultaneously isolate and reduce noise in the center of the patient's ear canal, further improving its sound insulation effect and helping to promote the patient's sleep quality.
[0017] Please refer to the attached instruction manual for details. Figure 2The side of the arc surface 33 is arc-shaped, and the connection between the arc surface 33 and the arc trajectory 32 is rounded. The arc bending direction of the flexible plate 34 points to the inner wall of the earmuff body 1. The entire flexible plate 34 is made of rubber material.
[0018] The specific implementation method is as follows: With the above settings, after the earmuff body 1 and the arc-shaped tightening ring 2 wrap around the user's ear contour, the flexible plate 34 can provide close-fitting support to the ear on the inner side of the ear contour, thereby forming a double-layer fixation measure of external wrapping and internal support for the user's ear. On the one hand, it effectively improves the wrapping effect, and on the other hand, it ensures that the overall force on the ear is uniform, avoiding discomfort and injury caused by uneven local force on the ear tissue.
[0019] Please refer to the attached instruction manual for details. Figure 3 The overall curvature formed by the circular end 35 and the flexible plate 34 is greater than the curvature of the inner wall of the earmuff body 1. The arc surface 33 can be twisted and adjusted in any direction toward the inner wall of the earmuff body 1 via the arc trajectory 32 on the surface of the base 31.
[0020] The specific implementation method is as follows: With the above settings, the arc-shaped surface 33 can be twisted and adjusted in any direction within the earmuff body 1 via the arc-shaped trajectory 32. When the arc-shaped surface 33 fits and supports the inner side of the patient's ear, it can adaptively change the support direction of the arc-shaped surface 33 according to the user's own posture changes, such as lying on the side or lying flat, thereby improving the comfort of the patient's ear and ensuring the support effect. In addition, the fitting posture of the arc-shaped surface 33 can be squeezed and changed according to the different ear contour shapes of different users. At the same time, the arc-shaped tightening ring 2 can adjust the elasticity of its own ring structure according to different contour sizes, so as to better adapt to the specific usage needs of different groups of people such as adults and children, and further improve the practical performance and economic value of the device.
[0021] Working principle of the invention: Step 1: First, the user fastens and wraps the earcup body 1 over the ear, and uses the elasticity of the arc-shaped tightening ring 2 to fasten the earcup body 1 securely over the user's ear.
[0022] Step 2: After the earmuff body 1 has finished wrapping the ear, the arc-shaped surface 33 inside the earmuff body 1 can fit against the center of the inner contour of the user's ear. At the same time, the flexible plate 34 on the side of the arc-shaped surface 33 will fit tightly against the inner edge of the patient's inner ear and continuously provide outward support to the edge of the ear. This works in conjunction with the earmuff body 1 and the arc-shaped tightening ring 2 to ensure that after the earmuff body 1 and the arc-shaped tightening ring 2 have wrapped the user's ear contour, the flexible plate 34 can simultaneously fit and support the ear on the inner side of the ear contour. This forms a double-layer fixation measure of external wrapping and internal support for the user's ear. On the one hand, it effectively improves the wrapping effect and ensures the patient's comfort. On the other hand, it can ensure that the overall force on the ear is even and avoid discomfort and injury caused by uneven force on the ear tissue.
[0023] Step 3: First, when the patient is sleeping and changes position, the curved surface 33 can be twisted and adjusted in any direction within the earmuff body 1 via the curved trajectory 32. When the curved surface 33 fits and supports the inside of the patient's ear, it can adaptively change the support direction of the curved surface 33 as the user's posture changes (such as lying on their side or flat), thereby improving the comfort of the patient's ear and ensuring its support effect, further improving the user's flexibility and practicality.
