[0034] An embodiment of the present application provides a hearing aid, comprising:

[0035] The housing comprises a base and a flip cover which is flipped on the base, wherein the base is provided with a first inner groove for placing an earphone inlet, a second inner groove for placing an earphone body, a third inner groove which is provided in the second inner groove and is used to place a controller, and a fourth inner groove which is connected to the third inner groove and is used to place a hanging rope;

[0036] The base is provided with an inner cavity, the heating element is arranged in the inner cavity, and is wrapped and sleeved on the first inner groove, the second inner groove, the third inner groove and the fourth inner groove.

[0037] The hearing aid provided above is provided with a heating element, and the heating element is made into a three-dimensional grid structure that can be wrapped and sleeved on the first inner groove, the second inner groove, the third inner groove and the fourth inner groove to reduce the volume of the heater, and by sleeved on the earphone inlet, the earphone body, the periphery of the controller, and the connection between the controller and the lanyard and other parts where there are openings and gaps, when the heating element heats up, it can dry out the moisture in the above openings and gaps, and can better prevent moisture from entering the earphone through the openings or gaps to ensure the service life of the hearing aid.

[0038] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] See also Figure 1-Figure 3The present application proposes a hearing aid 100, comprising: a shell 10, including a base 11 and a flip cover 12 flipped on the base 11, the base 11 is provided with a first inner groove 11a for placing the ear inlet 31 of the earphone 30, a second inner groove 11b for placing the main body 32 of the earphone 30, a third inner groove 11c opened in the second inner groove 11b and used for placing the controller 40, and a fourth inner groove 11d connected to the third inner groove 11c and used for placing the hanging rope 50; a heating element 20, the base 11 is provided with an inner cavity (not shown), the heating element 20 is arranged in the inner cavity, and is wrapped and sleeved on the first inner groove 11a, the second inner groove 11b, the third inner groove 11c and the fourth inner groove 11d.

[0040] It should be noted that, in the present application, the base 11 has a surface facing the flip cover 12, that is, the upper surface of the base 11, and the first inner groove 11a, the second inner groove 11b, the third inner groove 11c and the fourth inner groove 11d are opened on the above-mentioned surface.

[0041] In a specific embodiment, the shape of the heating element 20 is consistent with the shape of the above-mentioned surface, that is, the three-dimensional heating element 20 is located in the inner cavity and wrapped in the first inner groove 11a, the second inner groove 11b, the third inner groove 11c and the fourth inner groove 11d. Therefore, when the hearing aid 100 is used in a humid environment, or when the hearing aid 100 becomes damp due to long-term use, the three-dimensional heating element 20 generates heat, thereby heating and drying the hearing aid 100 to evaporate the water vapor in the hearing aid 100 to achieve a dry environment, thereby avoiding the problem that the openings and holes on the hearing aid 100 are located in a humid environment and the water vapor enters the hearing aid 100 through the openings and holes, thereby affecting the service life of the hearing aid 100.

[0042] Furthermore, the above-mentioned heating element 20 is formed by winding a heating wire. Compared with the existing products in which a heater is arranged in the hearing aid 100 (such as patent application document EP3697104A1), the present application replaces the existing heater with a heating element 20 formed by surrounding the heating element 20, thereby greatly reducing the overall volume and weight of the hearing aid 100, making it easier for the elderly to carry.

[0043] In another specific embodiment, the heating element 20 may also be an electric heating film.

[0044] Furthermore, since the first inner groove 11a is used to place the ear inlet 31 of the earphone 30, the second inner groove 11b is used to place the main body 32 of the earphone 30, the third inner groove 11c is used to place the controller 40, and the fourth inner groove 11d is used to support the connection part 214 between the controller 40 and the lanyard 50, the above-mentioned parts all have openings, or have splicing seams, or are parts where the lanyard 50 is connected to the electronic device, and they all have large or small holes, which are also parts where water vapor easily enters when there is water vapor in the hearing aid 100. The present application heats the above-mentioned openings or holes by wrapping the heating element 20 around the above-mentioned parts to evaporate the water vapor, thereby reaching a dry environment to avoid the influence of water vapor on the hearing aid 100.

[0045] In a specific embodiment, the heating element 20 includes a first heating part 21, a second heating part 22, a third heating part 23 and a fourth heating part 24; the first heating part 21 is wrapped and sleeved on the surface of the first inner groove 11a in the inner cavity, the second heating part 22 is wrapped and sleeved on the surface of the second inner groove 11b in the inner cavity, the third heating part 23 is sleeved on the surface of the third inner groove 11c in the inner cavity, and the fourth heating part 24 is wrapped and sleeved on the surface of the fourth inner groove 11d in the inner cavity.

[0046] In a specific embodiment, the first heating portion 21, the second heating portion 22, the third heating portion 23 and the fourth heating portion 24 are formed by winding a heating wire. When the heating wire is wound, it spirals at the first inner groove 11a, the second inner groove 11b, the third inner groove 11c and the fourth inner groove 11d to form the first heating portion 21, the second heating portion 22, the third heating portion 23 and the fourth heating portion 24.

[0047] It can be understood that, in another specific embodiment, the first heating portion 21, the second heating portion 22, the third heating portion 23 and the fourth heating portion 24 can also be formed by winding a plurality of heating wires, as follows:

[0048] Specifically, the first inner groove 11a has a first winding surface 111a in the inner cavity; the first winding surface 111a includes a first arcuate surface 111b and a second arcuate surface 111c arranged in sequence, the first arcuate surface 111b is arranged opposite to the sound outlet of the ear inlet 31 of the earphone 30, and the second arcuate surface 111c is arranged around and wrapped in the first inner groove 11a; the first heating part 21 includes a first heat generating part 211 and a fixing part 212 arranged on the first heat generating part 211, the first heat generating part 211 is wrapped around the first arcuate surface 111b, and is used to generate heat on the first arcuate surface 111b, and the fixing part 212 is wrapped and fixed on the second arcuate surface 111c.

[0049] It should be noted that, by setting the first heat generating part 211 on the first arc-shaped surface 111b, when the heat generating part of the heating element 20 generates heat, most of the heat generated is concentrated in the heat generating part, and the heat generating part is arranged opposite to the sound outlet of the earphone 30, so that when a large amount of heat is concentrated on the heat generating part, a large amount of heat can dry the space at the sound outlet of the earphone 30 to form a dry environment. Furthermore, by concentrating heat generation at the heat generating part, the present application avoids the problem that when the entire heating element 20 is uniformly heated, the heating temperature is deliberately raised to ensure that the important parts reach the specified temperature, resulting in excessive temperatures in other parts, which affects the function and life of the entire hearing aid 100.

[0050] Furthermore, by wrapping the fixing portion 212 around the second curved surface, the connection firmness between the heating element 20 and the base 11 is increased.

[0051] In a specific embodiment, the first heat generating portion 211 and the fixing portion 212 are integrally formed.

[0052] In order to generate heat only at the heat generating part, in a specific embodiment, the first heat generating part 21 further includes a heat generating component 213; there are multiple first heat generating parts 211, and the multiple first heat generating parts 211 are respectively connected to the heat generating component 213, and each of the first heat generating parts 211 is arranged in a circle to jointly surround and wrap around the first inner groove 11a.

[0053] It should be noted that in order to reduce the problem of heat loss during heat propagation, the above-mentioned embodiment uses multiple sections of heating wire to wind to form multiple first heat generating parts 211, and connects the multiple first heat generating parts 211 to the heat generating component 213, so that when the heat generating component 213 generates heat, the multiple first heat generating parts 211 can directly receive the heat from the heat generating component 213 and transfer the heat to the first curved surface, thereby concentrating the maximum heat to heat and dry the sound outlet of the earphone 30.

[0054] Preferably, in the above embodiment, each first heat generating portion 211 is arranged in a circle to avoid the problem of heat loss when heat is propagated in the first heat generating portion 211 .

[0055] It should be noted that when heat is transferred in a solid heating wire or other fixed material, heat conduction is mainly carried out through the vibration of atoms or molecules, and the vibration of atoms or molecules in the high temperature area is more intense than that in the low temperature area. Therefore, under the collision of molecules, heat is transferred from the hot end to the cold end, and the kinetic energy decay caused by heat loss to the air and collision between molecules causes heat loss during the transfer process. In the prior art, when heat is transferred by winding a heating wire, due to its long length, the part of the heating wire far away from the heat generating part is not utilized due to heat loss, resulting in low utilization of the heating wire. The present application sets a plurality of first heat generating parts 211, and sets each first heat generating part 211 in a circle to avoid the problem of low utilization of the first heat generating part 211 due to heat loss caused by the first heat generating part 211 being too long, thereby saving materials, reducing costs, and improving drying efficiency.

[0056] Furthermore, the first heating portion 21 further includes a plurality of connecting portions 214 ; each of the heat generating portions is fixed to the heat generating element 213 via one of the connecting portions 214 .

[0057] In a specific embodiment, the plurality of first heat generating parts 211 , the plurality of connecting parts 214 and the heat generating element 213 are integrally formed.

[0058] It should be noted that, in a specific embodiment, the connecting portion 214 is a heating wire, and the heat generating element 213 is a block-shaped resistance heater, which includes a block-shaped heating block, and the connecting portion 214 is also a heating wire structure, which is integrally formed. Preferably, when each connecting portion 214 connects the heat generating element 213 and a first heat generating portion 211, each heat generating portion is arranged downward in sequence along the vertical direction, that is, along the vertical direction, a plurality of first heat generating portions 211 are arranged around the first arc surface at equal intervals to heat different parts of the first arc surface, so as to improve the heating efficiency and avoid the problem of overheating in local areas caused by overlapping of different first heat generating portions 211. At the same time, the heating area and heating efficiency are maximized.

[0059] Furthermore, in order to facilitate the heat generation of the heat generating element 213, in a specific embodiment, the hearing aid 100 further includes a power module (not shown). The power module is disposed in the inner cavity of the base 11 and connected to the heat generating element 213, and is used to generate heat on the heat generating element 213. Specifically, in this embodiment, the heat generating element 213 is an electric heating block or the like.

[0060] In order to prevent the hearing aid 100 from overheating and causing damage to the hearing aid 100 or affecting the service life of the hearing aid 100, in a specific embodiment, the hearing aid 100 further includes a temperature sensor (not shown). The temperature sensor is disposed in the inner cavity of the base 11 and is electrically connected to the power module, and is used to control the power module to disconnect when it is detected that the temperature in the base 11 reaches a threshold.

[0061] It should be noted that, during the production process of the hearing aid 100, the electronic components in the hearing aid 100 are investigated to obtain the minimum temperature at which any component is damaged, and this temperature is set as the threshold temperature of the temperature sensor. A temperature sensor is set in the base 11 to detect the minimum problem of damaging any electronic component, so that when the temperature inside the hearing aid 100 reaches the above-mentioned temperature threshold, the temperature sensor controls the power module to disconnect, so as to disconnect the heat generating part 213, thereby stopping heat generation, so as to increase the service life of the hearing aid 100.

[0062] In order to better disconnect the heat generating component 213, in a specific embodiment, the hearing aid 100 further includes a fuse. The fuse is disposed in the inner cavity of the base 11 and is electrically connected between the temperature sensor and the power module, and is used to disconnect the power module when receiving a signal transmitted by the temperature sensor that the temperature reaches a threshold.

[0063] It should be noted that the power module, the temperature sensor and the fuse are parts of the prior art, and their specific principles will not be elaborated in detail here.

[0064] In order to facilitate carrying by the elderly, the hearing aid 100 further includes a hanging rope 50.

[0065] The hearing aid 100 provided above is provided with a heating element 20, and the heating element 20 is made into a three-dimensional grid structure that can be wrapped and sleeved in the first inner groove 11a, the second inner groove 11b, the third inner groove 11c and the fourth inner groove 11d to reduce the volume of the heater, and by sleeved on the ear inlet 31 of the earphone 30, the main body 32 of the earphone 30, the periphery of the controller 40 and the connection between the controller 40 and the hanging rope 50 where there are openings and gaps, so that when the heating element 20 generates heat, the moisture in the above-mentioned openings and gaps can be dried, and the moisture can be better prevented from entering the earphone 30 through the openings or gaps to ensure the service life of the hearing aid 100.

[0066] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
