Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, and in particular to an anti-earwax earmold and a hearing aid. Background Technology

[0002] Hearing aids are devices that provide hearing assistance to people with hearing impairments. Existing hearing aids generally include: a microphone for receiving external sounds, a speaker for transmitting sound into the ear, and an electronic processing device. Ear-hook hearing aids connect to an earmold through a sound tube. The earmold is inserted into the external auditory canal to transmit processed sound into the user's ear.

[0003] Because the earmold is inserted into the ear canal, earwax can easily stick to the earmold during normal use, blocking the sound tube or the front of the speaker, resulting in poor sound transmission. Since earwax is difficult to clean once it enters the sound tube, it affects the normal use of the hearing aid. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-earwax earmold and hearing aid, which has the advantages of being waterproof, anti-earwax, and easy to clean.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] According to a first aspect of the present disclosure, an anti-earwax earmold is provided, comprising:

[0007] The ear mold body has an internal hollowed-out cavity to form an installation chamber with an opening at the rear end, and a through sound guide hole is provided at the front end of the ear mold body.

[0008] A loudspeaker is disposed in the mounting chamber. The loudspeaker is connected to an outwardly extending sound guide tube. The sound guide tube is inserted and fixed in the sound guide hole, and there is a height difference between the front end of the sound guide tube and the outer surface of the ear mold to form an installation space.

[0009] A protective mesh cover is installed in the installation space and fixed to the front end of the sound guide tube and / or the inner wall of the sound guide hole. The outer surface of the protective mesh cover is basically flush with the outer surface of the ear mold body, and the inner surface of the protective mesh cover is loaded with a nano waterproof membrane layer.

[0010] To achieve the above technical solution, during use, the sound from the speaker is transmitted to the ear through the sound guide tube. Because a protective mesh is provided at the front end of the sound guide tube, earwax can be prevented from entering the sound guide tube, thus avoiding earwax blockage. The nano-waterproof membrane layer loaded on the protective mesh can seal the through holes on the protective mesh without affecting sound transmission, further blocking earwax. At the same time, the nano-waterproof membrane layer is also waterproof, preventing water vapor from entering the earmold body through the sound guide hole. Since the protective mesh is set, earwax will concentrate on the surface of the protective mesh and will not enter the sound guide hole, thus making the cleaning process more convenient.

[0011] In some exemplary embodiments, the front end of the sound guide hole is further provided with an assembly step hole, the bottom wall of the assembly step hole is flush with the end face of the sound guide tube, and the protective mesh cover is simultaneously adhered to the assembly step hole and the front end of the sound guide tube.

[0012] To achieve the above technical solution, by setting the assembly step hole to be flush with the front end face of the sound guide tube, the bonding and fixing area of ​​the protective netting is expanded, and the protective netting can be bonded to the assembly at the same time. This not only makes the bonding and fixing of the protective netting more convenient, but also further strengthens the connection strength between the sound guide tube and the earmold body, and improves the overall connection stability of the earmold body.

[0013] In some exemplary embodiments, the sidewalls of the mounting step hole are inclined inward to press against the side of the protective mesh cover.

[0014] In some exemplary embodiments, the inclination angle of the mounting step hole sidewall is 2-5°.

[0015] To achieve the above technical solution, the protective netting is reinforced and fixed by squeezing the side of the assembly step hole. In the initial stage of bonding the protective netting, the protective netting can be in close contact with the assembly step hole and the sound guide tube, so that the protective netting can be bonded stably.

[0016] In some exemplary embodiments, the protective mesh cover is arched, and the bottom wall of the mounting step hole is an arc surface adapted to the protective mesh cover.

[0017] The above technical solution enables the protective mesh to better fit the shape of the front end of the earmold and reduces the accumulation of earwax on the protective mesh.

[0018] According to a second aspect of the present disclosure, a hearing aid is provided, including an anti-earwax earmold as described in the first aspect.

[0019] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0020] This utility model embodiment provides an anti-earwax earmold and a hearing aid. The anti-earwax earmold includes: an earmold body with an internal hollowed-out mounting chamber forming an opening at the rear end, and a through sound guide hole at the front end of the earmold body; a speaker disposed within the mounting chamber, the speaker being connected to an outwardly extending sound guide tube, the sound guide tube being inserted and fixed within the sound guide hole, and a height difference between the front end of the sound guide tube and the outer surface of the earmold body forming an mounting space; and a protective mesh cover disposed within the mounting space and fixed to the front end of the sound guide tube and / or the inner wall of the sound guide hole. The outer surface of the protective mesh cover is substantially flush with the outer surface of the earmold body, and the inner surface of the protective mesh cover is coated with a nano-waterproof membrane layer. During use, the sound from the speaker is transmitted to the ear through the sound guide tube. Because the front end of the sound guide tube is equipped with a protective mesh, earwax can be prevented from entering the sound guide tube to avoid clogging it. The nano-waterproof membrane layer on the protective mesh can seal the through holes on the protective mesh without affecting sound transmission, further blocking earwax. At the same time, the nano-waterproof membrane layer is also waterproof, preventing moisture from entering the earmold body through the sound guide hole. Because of the protective mesh, earwax will concentrate on the surface of the protective mesh and will not enter the sound guide hole, making the cleaning process more convenient.

[0026] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 3As shown, the first aspect of this utility model provides an anti-earwax earmold, comprising: an earmold body 10, the earmold body 10 having a hollowed-out interior forming an installation chamber with an opening at the rear end, and a through sound guide hole 11 at the front end of the earmold body 10; a speaker 20 disposed in the installation chamber, the speaker 20 being connected to an outwardly extending sound guide tube 21, the sound guide tube 21 being inserted and fixed within the sound guide hole 11, and a height difference between the front end of the sound guide tube 21 and the outer surface of the earmold body 10 forming an installation space; and a protective mesh cover 30 disposed within the installation space and fixed to the front end of the sound guide tube 21 and / or the inner wall of the sound guide hole 11, the outer surface of the protective mesh cover 30 being substantially flush with the outer surface of the earmold body 10, and the inner surface of the protective mesh cover 30 being loaded with a nano-waterproof membrane layer 31.

[0028] Specifically, the ear mold 10 can be integrally formed by 3D printing or other methods. The surface of the ear mold 10 is smooth and preferably made of UV-curable transparent resin material. It can be understood that the installation chamber is the space inside the ear mold 10. The sound guide hole 11 is formed directly during the molding process of the ear mold 10. It is compatible with the sound guide tube 21, and the sound guide tube 21 can be bonded and fixed to the sound guide hole 11.

[0029] A mounting step hole 12 is also provided at the front end of the sound guide hole 11. The bottom wall of the mounting step hole 12 is flush with the end face of the sound guide tube 21. The protective net cover is simultaneously glued to the mounting step hole 12 and the front end of the sound guide tube 21. By setting the mounting step hole 12 to be flush with the front end face of the sound guide tube 21, the bonding and fixing area of ​​the protective net cover 30 is expanded. The protective net cover 30 can be glued to the assembly at the same time, which not only makes the bonding and fixing of the protective net cover 30 more convenient, but also further strengthens the connection strength between the sound guide tube 21 and the earmold body 10, and improves the overall connection stability of the earmold body 10.

[0030] The sidewall of the mounting step hole 12 is inclined inward to press against the side of the protective net cover 30. The inclination angle of the sidewall of the mounting step hole 12 is 2-5°. The sidewall of the mounting step hole 12 can undergo slight deformation so that the protective net cover 30 can be inserted into the mounting step hole 12. At this time, the sidewall of the mounting step hole 12 presses against the side of the protective net cover 30, thereby strengthening and fixing the protective net cover 30. In the initial stage of bonding the protective net cover 30, the protective net cover 30 can be in close contact with the mounting step hole 12 and the sound guide tube 21, so that the protective net cover 30 can be stably bonded.

[0031] Preferably, the protective mesh cover 30 is arched, and the bottom wall of the mounting step hole 12 is an arc surface that matches the protective mesh cover 30. It can be understood that the arched shape of the protective mesh cover 30 matches the arc shape of the front end of the earmold body 10, and it usually has only a slight curvature. The arc of the bottom wall of the mounting step hole 12 is also a slight curvature, so that the protective mesh cover 30 can better fit the shape of the front end of the earmold body 10 and reduce the accumulation of earwax on the protective mesh cover 30.

[0032] The nano-waterproof membrane layer 31 can be an existing pre-formed membrane, which is fixed to the protective net cover 30 by composite or adhesive methods. Alternatively, it can be formed by coating the inner surface of the protective net cover 30 with nano-waterproof materials, such as existing nano-coatings like nano-polyurethane coatings.

[0033] In use, the sound from the speaker 20 is transmitted to the ear through the sound guide tube 21. Since the front end of the sound guide tube 21 is equipped with a protective mesh cover 30, the protective mesh cover 30 can prevent earwax from entering the sound guide tube 21, thus preventing earwax from clogging the sound guide tube 21. The nano waterproof membrane layer 31 loaded on the protective mesh cover 30 can seal the through holes on the protective mesh cover 30 without affecting the sound transmission, further blocking earwax. At the same time, the nano waterproof membrane layer 31 is also waterproof, which can prevent water vapor from entering the ear mold body 10 from the sound guide hole 11. Since the protective mesh cover 30 is set, the earwax will concentrate on the surface of the protective mesh cover 30 and will not enter the sound guide hole 11, so the cleaning process is more convenient.

[0034] The second aspect of this utility model provides a hearing aid, including an anti-earwax earmold as described in the first aspect, a speaker 20 connected to an external host, the external host being used to receive and process external sound signals, and transmit the processed sound signals to the human ear through the speaker 20. The structure and function of the external host are prior art and will not be described in detail here.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
