Description

Technical Field

[0001] The utility model relates to the technical field of hearing aids, in particular to an adjustable hearing aid with an anti-slip structure. Background Art

[0002] Hearing aids are assistive devices used by people with hearing impairments. They are tools, equipment, devices and instruments used to make up for the defects caused by hearing loss and thus improve the ability to communicate with others. Hearing aids are composed of microphones, amplifiers, receivers and power supplies. Hearing aids are divided into low-power, medium-power and high-power according to the degree of sound amplification; according to the appearance, they are divided into box-type, behind-the-ear and in-the-ear types; according to the technology type, there are analog, digital programming and full-digital hearing aids; from the perspective of wearing position and appearance, they can be divided into behind-the-ear hearing aids, in-the-ear hearing aids, in-the-ear hearing aids and complete in-the-ear hearing aids.

[0003] For example, the Chinese patent (CN208337875U) discloses a non-slip hearing aid for the elderly, which includes a shell, a working component and a battery provided inside the shell, the working component being electrically connected to a sound guide tube, one end of the sound guide tube being connected to an ear mold, a volume control button being provided on the shell, a reel being provided at the bottom of the shell, an elastic band being wrapped around the reel, one end of the elastic band being connected to an elastic member, one end of the elastic member being connected to a fixed seat, a connecting shaft being clamped in the reel, a plurality of limit blocks being provided on the connecting shaft, a limit groove matching the limit blocks being provided in the reel, an end of the connecting shaft away from the reel passing through the inner wall of the shell and being fixedly connected to an adjusting button, the adjusting button being located on the outer wall of the shell, a plurality of blocks being provided on the outer edge of the adjusting button, the blocks being all fixedly connected to the adjusting button, and a slot matching the adjusting button being provided on the side wall of the shell. This utility model has strong practicality and is worthy of promotion.

[0004] The above solution also has the following technical deficiencies: it is not convenient to switch the fixing method of the hearing aid. The above solution only uses an elastic band to fix the hearing aid, which causes the user to have the elastic band tighten the ear for a long time, causing discomfort to the user when wearing the hearing aid and making it impossible to change the wearing method of the hearing aid. Based on this, an adjustable hearing aid with an anti-slip structure is proposed. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an adjustable hearing aid with an anti-slip structure.

[0008] By adopting this technical solution, the extension length of the elastic band can be adjusted according to needs.

[0009] Furthermore, the anti-slip fixing mechanism includes a mounting plate fixed to the front left side of the hearing aid body, a movable rod movably connected to the inside of the mounting plate, a second handle fixed to the front side of the movable rod, a suction cup fixed to the end of the movable rod away from the second handle, and a limiting assembly installed on the outer surface of the movable rod and the rear side of the mounting plate.

[0010] By adopting this technical solution, it is convenient for users to switch the way of fixing the hearing aid body.

[0011] Furthermore, the winding assembly includes a first baffle fixed to the end of the rotating rod away from the first handle, a winding drum fixed to the side of the first baffle away from the rotating rod, a second baffle fixed to the side of the winding drum away from the first baffle, a screw rod fixed to the side of the second baffle away from the winding drum, and a limit plate fixed to the side of the screw rod away from the second baffle, and one end of the elastic band is fixed to the outer surface of the winding drum.

[0012] By adopting this technical solution, the position of the elastic band wound on the winding drum can be changed when the elastic band is wound.

[0013] Furthermore, the limiting assembly includes a screw rod fixed on the outer surface of the moving rod and a threaded sleeve fixed on the rear side of the mounting plate, and the screw rod and the threaded sleeve are matched.

[0014] By adopting this technical solution, the suction cup can be limited.

[0015] Furthermore, a rotation hole is opened on the left side of the hearing aid body, and the rotation rod rotates in the rotation hole.

[0016] By adopting this technical solution, it is convenient for the rotating rod to drive the winding assembly to rotate.

[0017] Furthermore, a through hole is formed on the bottom side of the inner wall of the hearing aid body, and the elastic band slides in the through hole.

[0018] By adopting this technical solution, the elastic band can be easily rolled up and released.

[0019] Furthermore, a threaded hole is provided inside the support plate, and the screw rod is threadedly connected in the threaded hole.

[0020] By adopting this technical solution, it is convenient to support the winding mechanism.

[0021] Furthermore, one end of the elastic band away from the winding drum is fixed to the upper part of the right side of the hearing aid body, and the cotton sleeve is sleeved on the outer surface of the elastic band.

[0022] By adopting this technical solution, the discomfort caused by the elastic band to the user's ears can be reduced.

[0023] Furthermore, a moving groove is provided inside the mounting plate, and the moving rod moves in the corresponding moving groove.

[0024] By adopting this technical solution, it is convenient to use the moving rod to drive the suction cup to move.

[0025] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0026] This adjustable hearing aid with an anti-slip structure has an adjustment mechanism provided at the bottom end of the hearing aid body. The tightness of the hearing aid can be adjusted by changing the extended length of the elastic band. At the same time, the elastic band can be wound around different positions of the winding drum by changing the position of the winding drum, thereby preventing the elastic band from getting stuck due to crowded space. By providing an anti-slip fixing mechanism on the left side of the hearing aid body, the hearing aid body can be fixed on the skin by using a suction cup. At the same time, the suction force of the suction cup can prevent the hearing aid body from slipping off the user's ear, avoiding the discomfort caused by the user using the same method to fix the hearing aid body for a long time.
