[0002] With the continuous development of hearing aid technology, more and more hearing-impaired people choose to use hearing aids to improve their quality of life. A hearing aid is a small loudspeaker that amplifies sounds that are originally inaudible, and then uses the residual hearing of the hearing-impaired to send the sound to the auditory center of the brain, so that the sound can be felt; it is mainly composed of five parts: microphone, amplifier, earphone, power supply and volume control; it is classified into box type, glasses type, hairpin type, behind-the-ear type, in-the-ear type, ear canal type, and deep ear canal type hearing aids according to the way they are used.

[0003] Behind-the-ear hearing aids are popular among users due to their comfort and ease of operation. When wearing them, users need to hang the hearing aid body firmly on the back of the ear, insert the earplug part correctly into the external auditory canal, and then use the hearing aid to process the sound collected from the outside and transmit it to the patient's auditory center.

[0004] In hot weather or when doing sports, users will produce a lot of sweat around their ears. Since behind-the-ear hearing aids require the hearing aid body to be hung on the back of the ear, sweat can easily penetrate into the hearing aid along the side that fits the skin, causing damage to the internal electronic components and batteries, resulting in reduced performance or even damage to the hearing aid.

[0041] During use, when the heat dissipation component is started to drive the air to accelerate through the heat dissipation slot 2, the air forms contact heat exchange with the heat dissipation fins 19 and the surface of the heat dissipation plate 3, thereby effectively increasing the contact area between the heat dissipation plate 3 and the air, and improving the heat exchange efficiency of the heat dissipation plate 3.

The ceramic heat insulation board 21 is installed between the heat dissipation board 3 and the temperature conduction board 5 , and one end of the semiconductor cooling chip 4 is fixedly connected to the ceramic heat insulation board 21 .

[0045] During use, when the heat generated by the patient's ear is transferred to the surface of the thermal conduction plate 5 through the silicone insulating layer 6, the ceramic thermal insulation plate 21 is provided to isolate the thermal conduction plate 5 from the body 1, thereby reducing the direct transfer of heat from the surface of the thermal conduction plate 5 to the inside of the body 1, thereby reducing the heat accumulation inside the body 1 and affecting the normal operation of the body 1, thereby improving the practicability of the device.

[0049] When in use, firstly, the silicone cleaning ring 28 is driven to be inserted into the interior of the sound tube 8 by pulling the connecting tube 9, and the silicone cleaning ring 28 is made to come into contact with the inner wall of the sound tube 8, and deformed to fill the space between the connecting tube 9 and the sound tube 8, and then the threaded sleeve 25 is manually pulled to align with the locking screw head tube 26, and then the threaded sleeve 25 is rotated to form a threaded connection with the locking screw head tube 26, and the rubber sealing ring 27 is pushed to form an extrusion contact with one end of the locking screw head tube 26, so that the rubber sealing ring 27 is deformed by force and fills the gap between the threaded sleeve 25 and the locking screw head tube 26, thereby effectively improving the sealing effect between the connecting tube 9 and the sound tube 8, reducing the situation where sweat enters the interior of the sound tube 8, and improving the waterproof effect of the device; Then, after loosening the heat dissipation motor 15 to release the threaded connection with the locking screw tube 26, the connecting tube 9 is manually pulled to drive the silicone cleaning ring 28 to slide along the inner wall of the sound tube 8, and while it is separated from the inside of the sound tube 8, the silicone cleaning ring 28 produces a rebound deformation and fits the inner wall of the sound tube 8, driving the water vapor generated on the inner wall of the sound tube 8 to be discharged from the inside of the sound tube 8, thereby effectively improving the practicability of the device.

[0050] The implementation principle of the sweat-proof and moisture-proof behind-the-ear hearing aid of this embodiment is as follows: first, the silicone cleaning ring 28 is driven to be inserted into the interior of the sound tube 8 by pulling the connecting tube 9, and the silicone cleaning ring 28 is made to come into conflict with the inner wall of the sound tube 8, and deformed to fill the space between the connecting tube 9 and the sound tube 8, and then the threaded sleeve 25 is manually pulled to align with the locking screw head tube 26, and then the threaded sleeve 25 is rotated to form a threaded connection with the locking screw head tube 26, and the rubber sealing ring 27 is pushed to form an extrusion conflict with one end of the locking screw head tube 26, so that the rubber sealing ring 27 is deformed by force and fills the gap between the threaded sleeve 25 and the locking screw head tube 26; Then, the body 1 is pulled to drive the ear hook 7 to hook on the patient's ear, and the ear plug head 10 is pulled to be inserted into the cochlea, so that the body 1 drives the silicone isolation layer 6 to fit with one side of the patient's ear, and the ear hook 7 drives the temperature sensor 12 to fit with the patient's ear, and the temperature sensor 12 is used to monitor the temperature change of the patient's ear in real time. When the temperature sensor 12 detects that the patient's ear temperature rises to a preset value, the temperature sensor 12 sends a start signal to the semiconductor cooling chip 4 and the heat dissipation motor 15, and at the same time, the heat generated by the patient's ear is transferred to the surface of the heat conduction plate 5 through the silicone isolation layer 6, and the semiconductor cooling chip 4 starts to absorb the heat accumulated on the surface of the heat conduction plate 5, and then the semiconductor cooling chip 4 transfers the absorbed heat to the heat dissipation plate 3 through the heat release end, thereby reducing the temperature of the surface of the heat conduction plate 5, and then reducing the temperature of the fitting surface of the patient's ear and the silicone isolation layer 6, reducing the metabolism of the patient's ear, and reducing the amount of sweating in the patient's ear; Then, the heat dissipation motor 15 is started to drive the turbofan 14 to rotate, and the turbofan 14 sucks the outside air into the wind collection chamber 13 through the air inlet 16, and then discharges the air sucked into the wind collection chamber 13 into the heat dissipation tank 2 through the air guide 17, so that the air flows along the inner wall of the heat dissipation tank 2 and forms contact heat exchange with the surface of the heat dissipation plate 3, thereby cooling the surface of the heat dissipation plate 3, and then the air after heat exchange is discharged from the heat dissipation tank 2 through the air outlet 18; Finally, the threaded connection with the locking screw tube 26 is released by loosening the heat dissipation motor 15, and then the connecting tube 9 is manually pulled to drive the silicone cleaning ring 28 to slide along the inner wall of the sound tube 8, and while it is separated from the inside of the sound tube 8, the silicone cleaning ring 28 produces a rebound deformation and fits the inner wall of the sound tube 8, driving the water vapor generated on the inner wall of the sound tube 8 to be discharged from the inside of the sound tube 8.
