Technical Field
[0001] The utility model relates to the technical field of hearing aids, in particular to a hearing aid which is convenient to maintain. Background Art
[0002] A hearing aid is an electronic device designed to help hearing-impaired people improve their hearing. It works by capturing and amplifying sounds in the environment and transmitting them clearly to the user's ears. Hearing aids usually consist of a microphone, amplifier, and speaker. The device itself is small and easy to wear. It can be placed behind the ear, in the ear canal, or completely implanted in the body. The technology and design of hearing aids are constantly improving. Modern hearing aids can reduce background noise and enhance speech clarity through digital processing technology, and wirelessly connect to other devices such as phones and televisions, greatly improving the user's daily quality of life and communication efficiency.
[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "hearing aid for convenient replacement of earplug tips", and its application number is "CN202122779523.9". The patent mainly presses two protrusions at the same time and contracts the spring return rod until the block and the clamp no longer clamp the snap ring, and then pulls the snap ring out of the docking groove. At this time, it is convenient to separate the earplug head from the earphone head, thereby facilitating the replacement of earplug tips of various sizes, which is beneficial to improving the wearing comfort of the hearing impaired, and is convenient to clean the earwax on the earplug head, ensuring the normal hearing effect of the earplug head.
[0004] However, the device is not easy to maintain, especially for non-professionals. Since hearing aid components are extremely small and delicate, such as batteries, microphones, and circuit boards, users may encounter difficulties when repairing or cleaning them at home. This complexity not only increases the need to rely on professional service centers, but may also lead to higher maintenance costs. In addition, frequent maintenance needs—such as replacing batteries or cleaning earwax—can cause interruptions to daily use, especially for elderly users or people with physical disabilities, for whom operation of these small components may be particularly difficult. This maintenance inconvenience may limit some users from the full potential benefits they can obtain from hearing aids.
[0005] To this end, we propose a hearing aid that is easy to maintain. Utility Model Content
