Description

Technical Field

[0001] This disclosure relates to the field of hearing aid technology, and in particular to a hearing aid charging case and a hearing aid assembly. Background Technology

[0002] Hearing aids are a common tool used to improve hearing impairment. Used hearing aids require two steps: disinfection and drying. Disinfection removes germs from the surface of the hearing aid, while drying removes moisture to prevent a damp environment from forming in the user's ear when wearing it.

[0003] Currently, the disinfection process is mainly achieved by the user applying alcohol to the hearing aid with a cotton swab, while the drying process is mainly achieved by placing the hearing aid in a drying machine.

[0004] It is evident that the above-mentioned disinfection steps for hearing aids are relatively complex and inefficient. Utility Model Content

[0047] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0049] Hearing aids are common tools used to improve hearing impairment. When using a hearing aid, it needs to be inserted into the ear canal. After use, it needs to be removed and placed in the charging case for charging. Because hearing aids are frequently in contact with the ear canal, their surfaces accumulate bacteria. Users need to regularly disinfect and dry the surface to protect ear canal hygiene. Currently, disinfection is mainly achieved by applying alcohol to the hearing aid with a cotton swab, and drying is done by placing it in a drying machine. However, these disinfection procedures are relatively complex. Firstly, the drying process requires a separate time to complete, which is inefficient. Secondly, applying alcohol with a cotton swab may result in excessive alcohol being absorbed, potentially causing short circuits. Thirdly, alcohol is flammable and inconvenient to carry when using public transportation. These issues have become pain points for users and urgently need to be addressed.

[0050] This disclosure provides a hearing aid charging case, which includes a charging case body 1, a heating element 2, and an ultraviolet lamp 3.

[0051] The charging box body 1 has a receiving cavity 101 for receiving the hearing aid 02. The heating element 2 and the ultraviolet lamp 3 are located in the receiving cavity 101 and are respectively connected to the charging box body 1.

[0052] In this way, the hearing aid charging case is equipped with a heating element 2 and an ultraviolet lamp 3. When the user charges the hearing aid using the charging case after use, the heating element 2 and the ultraviolet lamp 3 can work simultaneously. The heating element 2 is used to raise the temperature inside the housing 101, heating and evaporating the moisture attached to the hearing aid 02, completing the drying step of the hearing aid 02. The ultraviolet lamp 3 is used to irradiate the hearing aid 02, removing germs attached to the hearing aid 02, completing the disinfection step. On the one hand, using this hearing aid charging case, the drying and disinfection steps can be completed during the charging process of the hearing aid 02, eliminating the need for separate time spent on drying and disinfection steps, thus improving efficiency. On the other hand, the disinfection step is completed by irradiation with the ultraviolet lamp 3, eliminating the need for the user to apply alcohol to disinfect the hearing aid 02, avoiding short circuits caused by excessive alcohol application, and eliminating the need for the user to carry alcohol, thus improving the convenience of the disinfection process.

[0053] It is understood that the “electrical connection” mentioned in the embodiments of this disclosure includes electrical connection through direct physical contact between components, as well as electrical connection through wire contact between components.

[0054] In some possible embodiments, the charging case body 1 includes a case, a circuit board 100, and a battery 200.

[0055] See Figure 1 The box has a receiving cavity 101, and a circuit board 100 is disposed in the receiving cavity 101 and connected to the box. The heating element 2 and the ultraviolet lamp 3 are both electrically connected to the circuit board 100. The battery 200 is electrically connected to the heating element 2 and the ultraviolet lamp 3 through the circuit board 100, respectively, to provide power for the operation of the heating element 2 and the ultraviolet lamp 3.

[0056] In one example, circuit board 100 is a printed circuit board (PCB), and battery 200 can be a hard-shell lithium battery.

[0057] Specifically, see Figure 1 The receiving cavity 101 includes a first receiving cavity 1011 and a second receiving cavity 1012 that are connected to each other. The second receiving cavity 1012 is used to receive the hearing aid 02, and the first receiving cavity 1011 is used to receive the circuit board 100. Correspondingly, the battery 200, the heating element 2 and the ultraviolet lamp 3 fixed to the circuit board 100 are also located in the first receiving cavity 1011.

[0058] In some possible embodiments, the charging case body 1 includes a base 11, a connecting plate 12, and a top cover 13.

[0059] like Figure 2 As shown, the charging case body 1 includes a base 11, a connecting plate 12, and a top cover 13.

[0060] The base 11 has an open end. A connecting plate 12 is located at the open end of the base 11 and is connected to the base 11. A first receiving cavity 1011 is formed between the connecting plate 12 and the base 11. The connecting plate 12 has a first through hole 121 and a second through hole 122. The first through hole 121 is arranged opposite to the heating element 2, and the second through hole 122 is arranged opposite to the ultraviolet lamp 3. The upper cover 13 is connected to the base 11. A second receiving cavity 1012 is formed between the upper cover 13 and the connecting plate 12. The second receiving cavity 1012 is connected to the first receiving cavity 1011 through the first through hole 121 and the second through hole 122.

[0061] For example, see Figure 2 The first through hole 121 can be a circular through hole, and the second through hole 122 can be a square through hole.

[0062] In this way, by setting the connecting plate 12, the box formed by the base 11 and the top cover 13 can be divided into a first receiving cavity 1011 and a second receiving cavity 1012. Furthermore, since the circuit board 100, battery 200, heating element 2 and ultraviolet lamp 3 are all located in the first receiving cavity 1011, the user will not come into contact with the heating element 2 and ultraviolet lamp 3 during daily use of the hearing aid charging box. On the one hand, this can avoid damage to the two due to contact, and on the other hand, it can improve the aesthetics of the hearing aid charging box.

[0063] In some possible embodiments, the connecting plate 12 has a plurality of first through holes 121, which are arranged at intervals and are respectively arranged opposite to the heating element 2.

[0064] See Figure 2 The circuit board 100 is located between the connecting plate 12 and the base 11 and is fixedly connected to the base 11. The hearing aid charging box includes multiple heating elements 2 arranged in a matrix. All heating elements 2 are located on the upper wall of the circuit board 100 and are electrically connected to the circuit board 100.

[0065] like Figure 2 As shown, multiple heating elements 2 are arranged in a matrix, and multiple heating elements 2 form a heating area on the circuit board 100. Multiple first through holes 121 are arranged at intervals and are respectively arranged opposite to the heating area.

[0066] In one example, the hearing aid charging case also includes a temperature sensor 500 and a control unit 700, with the temperature sensor 500 located between a plurality of heating elements 2, and the temperature sensor 500 and the control unit 700 electrically connected to the circuit board 100, respectively.

[0067] The temperature sensor 500 is used to detect the temperature in the heating area and send the temperature to the control unit 700. The control unit 700 is used to determine the difference between the temperature and the temperature threshold. When the temperature is less than the temperature threshold, the heating element 2 is controlled to work.

[0068] For example, the temperature threshold mentioned above can be 37°C.

[0069] In practice, multiple first through holes 121 can correspond to the positions of the receiver and earpiece of the hearing aid 02. The heating element 2 operates to raise the temperature in the heating area, evaporating the moisture attached to the receiver and earpiece of the hearing aid 02, thereby completing the drying step of the hearing aid 02.

[0070] In one example, see Figure 3 The first through hole 121 is a circular through hole, and the diameter of the first through hole 121 is located in the range of [1.5mm, 2mm].

[0071] This reduces the machining difficulty of the first through hole 121.

[0072] In some possible embodiments, see Figure 2 The connecting plate 12 has a receiving groove 123 on the wall of the second receiving cavity 1012. The receiving groove 123 is used to receive the hearing aid 02. The connecting plate 12 has a second through hole 122, which is arranged at intervals with the receiving groove 123.

[0073] In practice, with the hearing aid 02 placed in the receiving slot 123, the second through hole 122 is arranged opposite to the receiver of the hearing aid 02. The ultraviolet lamp 3 is located below the connecting plate 12, and the hearing aid 02 is located above the connecting plate 12. The ultraviolet lamp 3 and the receiver of the hearing aid 02 are arranged opposite to each other through the second through hole 122. The ultraviolet light emitted by the ultraviolet lamp 3 irradiates the receiver of the hearing aid 02, thereby removing germs attached to the receiver and completing the disinfection step of the hearing aid 02.

[0074] In one example, see Figure 3 The hearing aid charging case includes two ultraviolet lamps 3. The connecting plate 12 is located on the wall of the second receiving cavity 1012 and has two receiving slots 123. Each receiving slot 123 is used to receive a hearing aid 02. The connecting plate 12 has two second through holes 122, and each second through hole 122 is arranged at intervals corresponding to a receiving slot 123.

[0075] In practice, with the hearing aid 02 placed in the receiving slot 123, the two second through holes 122 are respectively arranged opposite to the receivers of the two hearing aids 02. The two ultraviolet lamps 3 are set below the connecting plate 12, and the two hearing aids 02 are set above the connecting plate 12. Each ultraviolet lamp 3 is arranged opposite to the receiver of one hearing aid 02 through a second through hole 122. The ultraviolet light emitted by the two ultraviolet lamps 3 irradiates the receivers of the two hearing aids 02, thereby removing germs attached to the receivers and completing the disinfection step of the hearing aid 02.

[0076] This can improve the disinfection effect of hearing aid 02.

[0077] Further, see Figure 2 The receiving slot 123 has charging pins 800 on its wall. There can be two charging pins 800: a positive charging pin and a negative charging pin. When the hearing aid 02 is placed in the receiving slot 123, the positive charging pin contacts the positive electrode of the hearing aid 02, and the negative charging pin contacts the negative electrode of the hearing aid 02, thus enabling the hearing aid charging case to charge the hearing aid 02.

[0078] In one example, see Figure 4The ultraviolet lamp 3 is located inside the second through hole 122.

[0079] Specifically, the ultraviolet lamp 3 may include a connecting part and an emitting part. The connecting part is electrically connected to the circuit board 100, and the emitting part is located inside and connected to the second through hole 122. The connection between the emitting part and the second through hole 122 may be adhesive or snap-fit, and this embodiment does not limit the method.

[0080] This improves the connection strength between the UV lamp 3 and the second through hole 122. Simultaneously, it prevents the UV light emitted by the UV lamp 3 from remaining within the first receiving cavity 1011, thus enhancing the disinfection effect of the hearing aid charging case on the hearing aid 02.

[0081] In one example, the base 11 and the top cover 13 are hinged together.

[0082] like Figure 2 As shown, a connecting seat 111 is provided on one side of the base 11, and a connecting head 131 is provided on one side of the top cover 13. The connecting head 131 is adapted to the connecting seat 111, and the connecting head 131 and the connecting seat 111 are hinged together by a hinge shaft 300 to realize the rotational connection between the base 11 and the top cover 13.

[0083] Furthermore, the other side of the base 11 may have a connected push button 112 and a first snap-fit ​​structure 113. The push button 112 is slidably connected to a receiving through hole opened on the outer wall of the base 11. Correspondingly, the other side of the top cover 13 has a second snap-fit ​​structure 132, which cooperates with the first snap-fit ​​structure 113.

[0084] In practice, when a user needs to charge the hearing aid 02 using the hearing aid charging case, a force can be applied to the push button 112 toward the hinge shaft 300, causing the first locking structure 113 and the second locking structure 132 to separate, thereby unlocking the base 11 and the top cover 13. Then, the top cover 13 can be rotated to separate the base 11 from the top cover 13, and the hearing aid 02 can be placed on the connecting plate 12 for charging.

[0085] Optionally, a torsion spring may be fitted on the outer wall of the hinge shaft 300, with the two pins of the torsion spring connected to the upper cover 13 and the base 11 respectively.

[0086] In this way, when the user needs to charge the hearing aid 02 using the hearing aid charging case, a force can be applied to the push button 112 toward the hinge shaft 300, causing the first snap-fit ​​structure 113 and the second snap-fit ​​structure 132 to separate. The top cover 13 and the base 11 can be directly pushed open by the spring force of the torsion spring, without the user having to manually rotate the top cover 13, thus improving the convenience of charging.

[0087] In one example, see Figure 1 The outer wall of the base 11 has a charging port 400.

[0088] like Figure 1 As shown, the charging port 400 penetrates the inner and outer walls of the base 11 and is electrically connected to the battery 200 via the circuit board 100. The charging port 400 may be located below the hinge 300. In this way, the charging port 400 will not obstruct the front of the hearing aid charging case when the charging cable is connected, which can improve the convenience of connecting the charging cable to the hearing aid charging case.

[0089] In some possible embodiments, the charging case body 1 also includes a reflector 4.

[0090] like Figure 4 As shown, the reflector 4 is located in the second receiving cavity 1012, is arranged opposite to the second through hole 122, and is connected to the upper cover 13.

[0091] This can improve the disinfection effect of the hearing aid charging case on hearing aid 02.

[0092] In practice, with the hearing aid 02 placed in the receiving slot 123, the ultraviolet lamp 3 is positioned opposite the receiver of the hearing aid 02 through the second through-hole 122. The ultraviolet lamp 3 is located below the receiver, and the ultraviolet light emitted by the ultraviolet lamp 3 cannot effectively irradiate the side wall of the receiver near the top cover 13, potentially affecting the disinfection effect of the hearing aid 02. A reflector 4 is installed on the top cover 13 within the second receiving cavity 1012. The reflector 4 can reflect the ultraviolet light emitted by the ultraviolet lamp 3, allowing the ultraviolet light to effectively irradiate the side wall of the receiver near the top cover 13, thereby improving the disinfection effect.

[0093] Optionally, such as Figure 4 The reflector 4 may be provided with multiple third through holes 41. (See reference) Figure 2 The third through hole 41 is used to connect the second receiving cavity 1012 with the external space.

[0094] For example, there may be multiple third through holes 41, which are circumferentially spaced along the edge of the reflector 4.

[0095] This prevents water droplets from adhering to the reflector 4, thus keeping the inside of the hearing aid charging case dry.

[0096] The technical solutions provided in this disclosure have at least the following beneficial effects:

[0097] This disclosure provides a hearing aid charging case. The charging case body 1 has a receiving cavity 101 for accommodating a hearing aid 02. A heating element 2 and an ultraviolet lamp 3 are located within the receiving cavity 101 and connected to the charging case body 1. Thus, with the heating element 2 and ultraviolet lamp 3 installed inside the charging case, the heating element 2 and ultraviolet lamp 3 can operate simultaneously when the user charges the hearing aid after use. The heating element 2 raises the temperature inside the receiving cavity 101, evaporating moisture adhering to the hearing aid 02, completing the drying step. The ultraviolet lamp 3 irradiates the hearing aid 02, removing germs adhering to it, completing the disinfection step. On one hand, using this hearing aid charging case, the drying and disinfection steps can be completed during the charging process of the hearing aid 02, eliminating the need for separate time-consuming drying and disinfection steps, thus improving efficiency. On the other hand, the disinfection process is completed by irradiation with ultraviolet lamp 3, which eliminates the need for users to apply alcohol to the hearing aid 02 for disinfection. This avoids short circuits caused by excessive alcohol application to the hearing aid 02, and users no longer need to carry alcohol, thus improving the convenience of the disinfection process.

[0098] This disclosure provides a hearing aid assembly, which includes the hearing aid charging case 01 and the hearing aid 02 described above.

[0099] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
