Technical Field

[0001] The utility model relates to a drying tank, in particular to a novel hearing aid drying box. Background Art

[0002] A hearing aid is a tool, device, apparatus and instrument that helps the hearing-impaired to improve their hearing impairment and improve their ability to communicate with others. It is a precision electronic instrument, so its use and maintenance are also very strict. Since hearing aids are in long-term use, they are inevitably corroded by sweat and moisture, which leads to a sharp decline in performance and seriously affects normal use. Therefore, dehumidification and drying of hearing aids has become the top priority of daily maintenance work.

[0003] The hearing aid drying tank is an important component for protecting the performance of hearing aids. Hearing aid drying tanks usually have the functions of preventing pressure, moisture-proof and dehumidification, especially moisture-proof and dehumidification. In daily life, the items to be dried and the desiccant are placed in the same closed container to absorb moisture and dry. The desiccant's hygroscopic properties are used to absorb moisture from the hearing aid to achieve the effect of moisture-proof and dehumidification. For example, application number 202222311762.6, patent name: A passive drying tank for hearing aids, with drying boxes installed at both ends of the tank body. The drying boxes are limited at both ends of the tank body by a sealing cover for drying hearing aids. However, the defects of the above design are:

[0004] The desiccant is placed in a sealed container (drying box). The amount of desiccant in the sealed container is limited, and the drying effect may be affected. In addition, if the desiccant is placed together with the product, once the container is opened by a child (the sealing cover is directly rotated to open), it is easy for the child to ingest it by mistake. Summary of the invention

[0005] The utility model aims to provide a novel hearing aid drying box. By using the structure, the safety of use can be effectively improved and the drying effect can be guaranteed.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a new hearing aid drying box, comprising a shell with an opening at the bottom and a box body rotatably arranged in the shell;

[0009] The elastic member pushes the housing to move upward when in an extended state, and the bottom surface of the second protrusion is arranged above the top surface of the first protrusion;

[0010] When the box body moves downward and compresses the elastic member, the bottom surface of the second protrusion is arranged below the side of the top surface of the first protrusion, the side wall of the second protrusion is arranged opposite to the side wall of the first protrusion, and when the shell rotates, the box body is driven to rotate via the first protrusion and the second protrusion.

[0011] In the above technical solution, the elastic member is a spring.

[0012] In the above technical solution, there are two first protrusions, and the two first protrusions are symmetrically arranged on both sides of the top surface of the box body;

[0013] There are two second protrusions, and the two second protrusions are symmetrically arranged on both sides of the top of the inner surface of the shell, and each second protrusion is respectively arranged on both sides between the two first protrusions.

[0014] In the above technical solution, a cavity is provided inside the shell, the bottom of the cavity is connected to the bottom of the shell, the box body is arranged in the cavity, and the second convex part is arranged on the top surface of the cavity.

[0015] In the above technical solution, a limiting ring extending inward is provided at the bottom of the shell, and the limiting ring is arranged below the edge of the bottom surface of the box body.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] Example 1: See Figures 1 to 3 As shown, a novel hearing aid drying box comprises a shell 1 with an opening at the bottom and a box body 2 rotatably disposed in the shell 1;

[0027] The top of the box body 2 is provided with at least one first protrusion 3, which is arranged beside the axis of the box body 2, and the top of the inner surface of the shell 1 is provided with at least one second protrusion 4, which is arranged beside the axis of the shell 1;

[0028] An elastic member 5 is installed on the top surface of the box body 2, and the top of the elastic member 5 is connected to the top of the inner surface of the shell 1;

[0029] When the elastic member 5 is extended, it pushes the housing 1 upwards and makes the bottom surface of the second protrusion 4 be arranged above the top surface of the first protrusion 3; that is, the elastic member 5 gives the housing 1 an upward thrust and pushes the bottom surface of the second protrusion 4 to be arranged above the top surface of the first protrusion 3;

[0030] When the box body 2 moves downward and compresses the elastic member 5, the bottom surface of the second protrusion 4 is arranged below the side of the top surface of the first protrusion 3, and the side wall of the second protrusion 4 is arranged opposite to the side wall of the first protrusion 3. When the shell 1 rotates, the box body 2 is driven to rotate via the first protrusion 3 and the second protrusion 4.

[0031] See also Figure 2 As shown, a cavity 6 with a bottom opening is provided in the box body 2 , and an internal thread 7 is provided on the inner surface of the cavity 6 .

[0032] In this embodiment, in actual use, the hearing aid to be dried is placed in a can body, and the box body is directly threadedly connected to the opening of the can body through its internal thread, so that the can body is closed, and the hearing aid is dried using the drying material in the box body. In the initial state, the elastic member is in a restored state, that is, the elastic member gives an upward thrust to the shell, pushing the shell to move upward, so that the second protrusion moves upward away from the top surface of the box body, so that there is a vertical gap between the top surface of the first protrusion and the bottom surface of the second protrusion, so that when the shell is subjected to a rotational force, it will only rotate relative to the box body, and the box body will not rotate with it. When the box body and the tank body need to be screwed together (taking the example of rotating the box body clockwise to achieve the threaded connection between the box body and the tank body, and rotating the box body counterclockwise to achieve the disassembly of the box body and the tank body), the box body is first placed on the tank body, with the internal thread of the cavity facing the external thread of the tank body. Then the operator applies downward pressure to the shell to push the shell downward relative to the box body (that is, the top of the shell is close to the top of the box body). The shell compresses the elastic member, so that the second protrusion moves downward, and the bottom surface of the second protrusion is close to the top surface of the box body. In this way, the bottom of the second protrusion is The second convex part will be located below the top surface of the first convex part, and the side wall of the second convex part will face the side wall of the first convex part. In addition, while applying downward pressure to the shell, the shell is given a clockwise rotation force, so that the second convex part will rotate clockwise with the shell. Since the side wall of the second convex part will face the side wall of the first convex part, the side wall of the second convex part will contact the side wall of the first convex part, and then the first convex part will be pushed to rotate with the second convex part, so that the box body is driven to rotate clockwise through the rotation of the first convex part, so as to achieve the screw connection between its internal thread and the external thread of the tank body. After the box body is tightened, the downward pressure and the rotating wheel of the shell are released, and the restoring force of the elastic member pushes the shell to rise, so that the bottom surface of the second convex part is above the top surface of the first convex part. In this way, even if the shell is given a rotation force, the side wall of the second convex part will not contact the side wall of the first convex part, and the shell will rotate relative to the box body, unable to drive the box body to rotate, and unable to achieve the disassembly of the box body and the tank body, preventing children from misoperating and preventing the internal dry substances from leaking out and being eaten by mistake. When the box body and the tank body need to be disassembled, the outer shell is subjected to downward pressure and counterclockwise rotation force in the same manner as above. The second protrusion descends and rotates counterclockwise, and the first protrusion is pushed to rotate counterclockwise by the second protrusion, thereby synchronously driving the box body to rotate counterclockwise and be disassembled from the tank body.

[0033] In this embodiment, the elastic member is a spring.

[0034] The top of the spring is connected to the top of the inner surface of the shell, and the bottom is connected to the top surface of the box body, so that when the shell rotates and presses down, the two ends of the spring will contact the top of the inner surface of the shell and the top surface of the box body respectively, so that the shell will always be pushed up and the second protrusion will be away from the first protrusion. Preferably, the top of the elastic member is rotatably connected to the top of the inner surface of the shell, the bottom of the elastic member is rotatably connected to the top surface of the box body, and the elastic member is coaxially arranged with the box body and the shell, so that when the shell rotates, the elastic member will not be damaged or damaged by torsion deformation.

[0035] See also Figure 2 , 3 As shown, there are two first protrusions 3, and the two first protrusions 3 are symmetrically arranged on both sides of the center of the top surface of the box body 2;

[0036] There are two second protrusions 4 , which are symmetrically arranged on both sides of the top center of the inner surface of the housing 1 , and each second protrusion 4 is respectively arranged on both sides between the two first protrusions 3 .

[0037] A cavity 8 is provided inside the housing 1 , the bottom of the cavity 8 is communicated with the bottom of the housing 1 , the box body 2 is disposed in the cavity 8 , and the second protrusion 4 is disposed on the top surface of the cavity 8 .

[0038] In this embodiment, the second protrusion preferably adopts an arc-shaped structure, which is located between the two first protrusions. In this way, after the shell is pressed down, whether it is rotated clockwise or counterclockwise at a small angle, it can contact the first protrusion on one side of the rotation direction to drive the box body to rotate, thereby improving the convenience of rotation.

[0039] See also Figure 2 As shown, the bottom of the housing 1 is provided with a limiting ring 9 extending inward, and the limiting ring 9 is arranged below the edge of the bottom surface of the box body 2. The limiting ring will be below the outer side of the internal thread, will not block the internal thread, and will not affect the screw connection of the box body.

[0040] By setting the limiting ring, when the outer shell moves upward due to the thrust of the elastic member, the outer shell will be limited by the limiting ring and the box body, so that the outer shell cannot move upward and separate from the box body, thereby preventing the outer shell from separating from the box body. When the outer shell moves downward, it will be limited by the top surface of the box body. Therefore, the setting of the limiting ring can limit the axial movement of the outer shell relative to the box body.

[0041] See also Figure 2 As shown, an extension ring 10 extending downward is provided in the middle of the top surface of the cavity 6, and the interior of the extension ring 10 constitutes a dry particle placement cavity with an open bottom. A sealing member 11 is provided at the bottom of the dry particle placement cavity, and dry particles 12 are placed in the dry particle placement cavity above the sealing member 11.

[0042] The extension ring is located at the inner end of the internal thread, and the dry particles are placed in the dry particle placement cavity formed by the extension ring and the shell, so that after the box body is screwed to the tank body by the internal thread, the extension ring and the dry particles can be inserted into the tank body, and the hearing aid placed in the tank body is dried by the dry particles. The sealing member is used to limit the dry particles in the dry particle placement cavity to prevent them from falling out.

[0043] Wherein, the sealing member comprises a moisture-absorbing paper sheet and a sealing aluminum foil arranged on the bottom surface of the moisture-absorbing paper sheet, and the edge of the top surface of the moisture-absorbing paper sheet is connected to the bottom surface of the extension ring.

[0044] The hygroscopic paper can not only limit the dry particles and prevent them from falling out, but also be breathable and hygroscopic, so as not to affect the drying of the hearing aid in the tank by the dry particles. At the same time, the sealing aluminum foil is used to seal the hygroscopic paper. When not in use, the sealing aluminum foil is used to seal to prevent the dry particles and the hygroscopic paper from absorbing external moisture, thereby ensuring the dryness of the dry particles and the hygroscopic paper and maintaining their drying effect. When the hearing aid needs to be dried, the sealing aluminum foil can be torn off, so that the hygroscopic paper and the dry particles can dry the hearing aid in the tank.
