Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, and in particular to a novel ear cover structure for in-ear hearing aids. Background Technology

[0002] In-the-ear (ITE) hearing aids are widely used by people with hearing impairments due to their small size and discreet wearing style. However, most existing ITE hearing aids have a single, fixed earpiece structure, which has the following technical drawbacks:

[0003] Poor fit: Traditional ear tips do not fully match the natural curve of the human ear canal (such as the curvature and diameter changes of the outer section of the ear canal), which can easily cause local pressure or gaps when worn, resulting in low comfort and may affect the hearing aid effect due to poor sealing.

[0004] Inconvenient maintenance: The ear tips and the main body of the hearing aid are mostly molded as one piece or have an interference fit, making disassembly difficult. After long-term use, the earwax accumulated inside the ear tips is difficult to clean, which can easily breed bacteria and affect hygiene and safety.

[0005] Easy to fall off: In mobile scenarios such as walking and exercising, the friction between traditional ear tips and the ear canal is insufficient, and the hearing aid is easily shaken by external force, causing the entire hearing aid to fall off, which poses a risk of loss or damage.

[0006] Limited adaptability: Most existing ear tips are of a fixed size, which cannot meet the ear canal size needs of different users (such as adults, children, and people with different ear canal sizes). Some users need to customize ear tips, which increases the cost of use.

[0007] To address the aforementioned issues, there is an urgent need to design a new type of ear cover structure that conforms to the human ear canal, is easy to disassemble and clean, prevents it from falling off, and is compatible with multiple sizes. Utility Model Content

[0008] This invention provides a novel ear cover structure for in-ear hearing aids, which can solve the problems mentioned in the background art.

[0009] This utility model provides a novel ear cover structure for an in-ear hearing aid, including:

[0010] The ear cover body has a buckle groove at its rear end;

[0011] Ear covers, including small ear covers, medium ear covers and large ear covers, and the small ear covers, medium ear covers and large ear covers are all provided with inner grooves;

[0012] The hearing aid body that is fitted and connected to the ear tips;

[0013] The hearing aid body includes a rear shell, buttons, a PCB board, a front shell, a hearing aid module, a sound cavity shell, and a sound cavity module.

[0014] The novel ear cover structure for an in-ear hearing aid according to one embodiment of this utility model further includes:

[0015] A protrusion located on the outside of the sound cavity shell and adapted to the snap-fit ​​groove.

[0016] The novel ear cover structure for an in-ear hearing aid according to one embodiment of this utility model further includes:

[0017] An external protrusion groove is located on the outside of the sound cavity shell and is adapted to the inner groove.

[0018] In a novel ear cover structure for an in-ear hearing aid according to an embodiment of this utility model, the outer sides of the small, medium, and large ear covers are all provided with anti-slip textures.

[0019] In the novel ear cover structure of the in-ear hearing aid according to one embodiment of this utility model, the ear cover body, small ear cover, medium ear cover and large ear cover are all medical soft silicone.

[0020] In a novel ear cover structure for an in-ear hearing aid according to one embodiment of this utility model, the diameter of the small ear cover is 5-6mm.

[0021] In a novel ear cover structure for an in-ear hearing aid according to one embodiment of this utility model, the diameter of the medium-sized ear cover is 7-8mm.

[0022] In a novel ear cover structure for an in-ear hearing aid according to one embodiment of this utility model, the diameter of the large ear cover is 9-10mm.

[0023] The technical solutions provided in this application embodiment may include the following beneficial effects: This application designs a new ear cover structure for in-ear hearing aids. First, the fit and comfort are improved: the segmented arc structure of the ear cover body perfectly matches the physiological curve of the human ear canal, and the medical soft silicone material can adapt to deformation, avoid local pressure, and there is no discomfort when wearing it for a long time.

[0024] Secondly, portability and cleanability are optimized: the snap-on connection allows for quick assembly and disassembly of the ear tips and the hearing aid body, while the threaded connection facilitates the individual replacement of the ear caps. During cleaning, the ear tips and ear caps can be completely removed to thoroughly remove earwax and ensure hygiene.

[0025] Next, the anti-drop effect is remarkable: the "three-point support" fit structure combined with the anti-slip texture of the ear cap greatly increases the friction between the ear cap and the ear canal, effectively preventing the hearing aid from falling out even in moving scenarios such as running and going up and down stairs.

[0026] Finally, it is highly versatile: the three sizes of ear tips can cover the ear canal size needs of most users, eliminating the need for customization, reducing usage costs, and making it easy for users to change to the appropriate ear tips according to changes in their own ear canal (such as when the skin of the ear canal is swollen).

[0027] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Example:

[0040] like Figures 1 to 6 As shown, this application provides a novel ear cover structure for an in-ear hearing aid, including: an ear cover body 1, with a snap-fit ​​groove 101 at the rear end of the ear cover body 1; an ear cover 2, including a small ear cover 21, a medium ear cover 22, and a large ear cover 23, with an inner groove 201 inside each of the small ear cover 21, medium ear cover 22, and large ear cover 23; and a hearing aid body 3 that is adapted to and connected to the ear cover 2; the hearing aid body 3 includes a rear shell 31, a button 32, a PCB board 33, a front shell 34, a hearing aid module 35, a sound cavity shell 36, and a sound cavity module 37.

[0041] The button 32 corresponds to the PCB board 33, the hearing aid module 35 is located in the middle of the front shell 34 and is installed by bolts, and the sound cavity shell 36 is connected to the front shell 34 by a snap-fit.

[0042] By adopting the above technical solution, through the setting of three different models of ear tips 2 and ear tip body 1, buckle groove 101, protrusion 301 and external protrusion groove 302, the problem of poor fit of traditional ear tips can be solved: traditional ear tips 1 do not fully match the natural curve of the human ear canal (such as the curvature of the outer section of the ear canal and the change in diameter), and local pressure or gaps are likely to occur when wearing them, resulting in low comfort and potentially affecting the hearing aid effect due to poor sealing;

[0043] Inconvenient maintenance: The ear cover 1 and the hearing aid body 3 are mostly integrally molded or interference fit, making disassembly difficult. After long-term use, the earwax accumulated inside the ear cover 1 is difficult to clean, which easily breeds bacteria and affects hygiene and safety.

[0044] Easy to fall off: In mobile scenarios such as walking and exercising, the friction between the traditional ear tip 1 and the ear canal is insufficient, and the hearing aid is easily shaken by external force, causing the entire hearing aid to fall off, which poses a risk of loss or damage.

[0045] Limited adaptability: Most existing ear tips are of a fixed size, which cannot meet the ear canal size needs of different users (such as adults, children, and people with different ear canal sizes). Some users need to customize ear tips, which increases the cost of use.

[0046] In an optional embodiment, the protrusion 301, which is located on the outside of the acoustic cavity shell 36 and is adapted to the snap-fit ​​groove 101, can wrap around the outside of the hearing aid body 3 through the ear cover body 1 during the installation process between the ear cover body 1 and the hearing aid body 3. At the same time, the protrusion 301 and the snap-fit ​​groove 101 engage to limit the ear cover body 1 and ensure the stability of the ear cover body 1 during use.

[0047] Quick assembly and disassembly are achieved through a snap-fit ​​connection (when disassembling, simply pull the back end of the earpiece body 1 to detach it from the hearing aid body 3);

[0048] One side of the ear cup body 1 is equipped with a pull ring, which serves as a grip during the disassembly and removal of the ear cup body 1, making it convenient to pull the ear cup body 1.

[0049] The main body of the ear cover 1 adopts a "segmented arc structure", which is designed with a natural arc according to the anatomical structure of the human ear canal and matches the physiological curvature of the outer segment of the ear canal; it fits against the skin around the ear canal opening to form a "three-point support" structure to ensure overall fit.

[0050] In an optional embodiment, it further includes: an external protrusion 302 disposed on the outside of the acoustic cavity shell 36 and adapted to the inner groove 201, wherein when the ear sleeve 2 is installed between the ear sleeve 2 and the ear sleeve body 1, the inner groove 201 and the external protrusion 302 engage to complete the positioning of the ear sleeve 2.

[0051] The ear tip body 1 and the hearing aid body 3 are connected by a deformed enlarged inner hole, and the replacement can be completed simply by pulling down the ear tip 2.

[0052] In an optional embodiment, the outer sides of the small ear tips 21, medium ear tips 22, and large ear tips 23 are provided with anti-slip textures to increase friction with the inner wall of the ear canal. At the same time, the gaps between the textures can accommodate a small amount of earwax, reducing the impact of earwax on the fit.

[0053] In an optional embodiment, the ear cover body 1, the small ear cover 21, the medium ear cover 22, and the large ear cover 23 are all made of medical-grade soft silicone, which provides both softness and elasticity during use, allowing them to deform slightly according to the shape of the ear canal and reduce pressure.

[0054] In an optional embodiment, during standard ear canal fitting:

[0055] Hold the hearing aid body 3 and gently press the buckle groove 101 at the rear end of the ear cover body 1 against the protrusion 301 at the front end of the hearing aid body 3 until it fits completely, confirming that the connection between the ear cover body 1 and the hearing aid body 3 is firm.

[0056] Select medium-sized ear tips 22, with an optimal diameter of 7.5mm. Align and press the inner groove 201 on the inside of the medium-sized ear tip 22 with the outer protrusion 302 at the front of the hearing aid body 3 until the medium-sized ear tip 22 fits tightly against the hearing aid body 3.

[0057] When wearing, insert the medium-sized ear tip 22 into the ear canal slowly along its natural curve until the rear section of the ear tip body 1 fits against the ear canal opening. At this point, the arc-shaped structure of the middle section of the ear tip body 1 matches the curved section of the ear canal without any pressure. When walking or exercising slightly, the anti-slip texture on the outside of the medium-sized ear tip 22 rubs against the inner wall of the ear canal, and the hearing aid body 3 shows no signs of shaking or falling off.

[0058] In an optional embodiment, during the ear canal fitting process:

[0059] Select the small ear tip 21, with an optimal diameter of 5.5mm, and assemble it with the ear tip body 1 and the hearing aid body 3 according to the method described in the above embodiment;

[0060] The soft silicone material of the ear cover body 1 can reduce irritation to the skin of the ear canal, and the front section of the segmented arc structure has a smaller diameter to avoid insertion too deep;

[0061] The three-point support structure and anti-slip texture of the ear tip body 1 work together to effectively prevent the hearing aid from falling off. At the same time, the ear tip body 1 is easy to disassemble, and parents can remove it regularly for cleaning to prevent bacterial growth.

[0062] In an optional embodiment, during the cleaning and replacement of the ear cover body 1:

[0063] When cleaning, hold the hearing aid body 3 with one hand and gently pull the rear end of the ear cover body 1 with the other hand to disengage the buckle slot 101 from the protrusion 301 and remove the entire ear cover body 1 structure.

[0064] At the same time, separate the ear cover 2 from the hearing aid body 3, and use medical alcohol swabs to wipe the inner wall and outer wall of the ear cover body 1 and the inner and outer surfaces of the ear cover 2 to remove earwax;

[0065] When the ear tip body 1 shows signs of aging (such as hardening of silicone or wear of texture), simply replace the ear tip body 1 with a new one, without having to replace the hearing aid body 3, thus reducing maintenance costs.
