Description

Technical Field

[0001] This utility model relates to the field of hearing aid technology, specifically to a sweat-proof hearing aid. Background Technology

[0002] Behind-the-ear (BTE) hearing aids are one of the most common types of hearing aids. The main body of an behind-the-ear hearing aid is hung behind the ear, and a sound tube transmits sound to the earplug or earmold in the ear canal.

[0003] When exercising, working, or in hot weather, people tend to sweat. Sweat may flow down the auricle onto the ear-hook hearing aid, enter the hearing aid, corrode electronic components, and affect the performance and lifespan of the hearing aid. Utility Model Content

[0004] The purpose of this invention is to provide a sweat-proof hearing aid to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sweat-proof hearing aid, comprising a hearing aid, wherein an earplug is provided on the hearing aid;

[0006] The hearing aid is equipped with a flow guiding mechanism, which includes a support rod and a flow guiding shell. One end of the support rod is fixedly connected to a support plate, and a round tube is fixedly connected to the support plate. One end of the round tube is fixedly connected to a limiting plate. A pressure groove is formed in the middle of the limiting plate. A compression bolt is threadedly connected to the support plate at the position corresponding to the round tube. A connecting groove is formed on the outer wall of the flow guiding shell, and a limiting groove is formed on the outer wall of the flow guiding shell at the position corresponding to the connecting groove.

[0007] Preferably, the support rod is fixedly connected to the outer shell of the hearing aid, and the flow guide shell is coated with a fluoropolymer coating.

[0008] Preferably, one end of the circular tube is slidably connected inside the connecting groove, and the connecting groove and the limiting groove are in communication.

[0009] Preferably, the limiting plate is slidably connected inside the limiting groove, the pressure groove is conical, and the limiting plate is made of rubber.

[0010] Preferably, one end of the extrusion bolt is located inside the circular tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by using a diversion mechanism, when sweat drips onto the diversion shell, the sweat will quickly condense into water droplets. These water droplets, thanks to the unique surface structure and tilt angle of the diversion shell, flow away along a predetermined diversion path. In this way, the sweat is effectively blocked outside the hearing aid and cannot penetrate the delicate electronic component area inside, thus building a solid protective barrier for the hearing aid and greatly extending its service life.

[0016] 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.

[0017] Please see Figure 1-3 The present invention provides the following technical solution:

[0018] Example 1: A sweat-proof hearing aid, including a hearing aid 1, with an earplug 2 provided on the hearing aid 1;

[0019] When in use, the user can directly hang the hearing aid 1 behind the ear and then accurately insert the earplug 2 into the ear canal to achieve the sound-assisted hearing function.

[0020] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a flow guiding mechanism 3 on the hearing aid 1, the flow guiding mechanism 3 including a support rod 31 and a flow guiding shell 32, a support plate 33 fixedly connected to one end of the support rod 31, a round tube 34 fixedly connected to the support plate 33, a limiting plate 35 fixedly connected to one end of the round tube 34, a pressure groove 36 opened at the middle position of the limiting plate 35, a compression bolt 37 threadedly connected to the support plate 33 at the position corresponding to the round tube 34, a connecting groove 38 opened on the outer wall of the flow guiding shell 32, and a limiting groove 39 opened on the outer wall of the flow guiding shell 32 at the position corresponding to the connecting groove 38;

[0021] The support rod 31 is fixedly connected to the outer shell of the hearing aid 1. The flow guide shell 32 is coated with a fluoropolymer coating. One end of the round tube 34 is slidably connected to the inside of the connecting groove 38. The connecting groove 38 and the limiting groove 39 are in communication. The limiting plate 35 is slidably connected to the inside of the limiting groove 39. The pressure groove 36 is tapered. The limiting plate 35 is made of rubber. One end of the extrusion bolt 37 is located inside the round tube 34.

[0022] Before wearing the hearing aid 1, the position of the flow guide shell 32 can be adjusted. The position of the flow guide shell 32 needs to be adjusted according to actual usage requirements. The flow guide shell 32 can be pushed up or down, and it will slide along the outer shell of the hearing aid 1. The round tube 34, limiting plate 35, connecting groove 38, and limiting groove 39 serve as guides and limits. After adjusting the flow guide shell 32, the pressing bolt 37 can be directly rotated. Supported by the support plate 33, the pressing bolt 37 moves towards the pressure groove 36 on the limiting plate 35. The moving pressing bolt 37 will press against the pressure groove 36, causing... The pressure groove 36 deforms, which in turn causes the limiting plate 35 to deform, thereby increasing the friction between the limiting plate 35 and the limiting groove 39. At this point, the flow guide shell 32 is fixed, and the hearing aid 1 can be worn normally. The sweat from the user's temples will drip into the flow guide shell 32. The fluoropolymer coating on the flow guide shell 32 will cause the sweat to quickly condense into water droplets, which will then flow away along the flow guide shell 32. The sweat is effectively blocked outside the hearing aid 1 and cannot penetrate the delicate electronic component area inside, thus building a solid protective barrier for the hearing aid 1 and greatly extending its service life.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
