Description

Technical Field

[0001] This application relates to the field of protective cover technology, and more particularly to a waterproof and dustproof hearing aid protective cover. Background Technology

[0002] Hearing aids, as important hearing assistive devices, can help people with hearing loss regain some auditory function and significantly improve their quality of life. Hearing aids typically consist of a main body (including a microphone, speaker, amplifier, battery compartment, etc.) and connecting components (such as a rod structure and silicone earplugs). During use, the main body of the hearing aid is exposed to the outside environment and is susceptible to its effects. To extend the lifespan of the hearing aid and ensure its performance, many hearing aids are equipped with protective covers to provide basic protection.

[0003] However, existing hearing aid protective cases have several drawbacks. Traditional cases primarily focus on preventing physical damage such as impacts or scratches, and are typically placed inside the case only when the user is not using the hearing aid, providing temporary protection. This design fails to provide effective waterproof and dustproof protection for the main body of the hearing aid during use. While silicone earplugs do not require waterproof and dustproof features because they fit snugly into the ear canal and provide a certain degree of seal, the main body of the hearing aid (especially components such as the microphone, speaker, and battery compartment) is prone to water and dust ingress in humid or dusty environments. This can not only affect the normal operation of the hearing aid, leading to sound distortion and performance degradation, but may even damage internal electronic components, increasing repair and replacement costs. Furthermore, traditional protective cases cannot provide comprehensive protection for the hearing aid during use, with insufficient sealing being a particularly prominent issue.

[0004] To address the aforementioned issues, it is necessary to propose a waterproof and dustproof hearing aid protective cover to prevent moisture and dust from entering the main body of the hearing aid, while ensuring that the hearing aid's sound pickup, output functions, and user experience are not affected. Utility Model Content

[0005] The purpose of this application is to overcome the shortcomings of the prior art and propose a waterproof and dustproof hearing aid protective cover to solve the problem of moisture and dust entering the main body of the hearing aid.

[0006] This application is achieved through the following technical solution:

[0007] This application proposes a waterproof and dustproof hearing aid protective cover, comprising:

[0008] The flexible silicone sleeve has a receiving groove and a bag opening connected to the receiving groove. The main body of the hearing aid is placed in the receiving groove through the bag opening, and the rod-shaped structure of the hearing aid passes through the bag opening.

[0009] The retraction component includes a cord that wraps around the opening of the flexible silicone sleeve. When the cord is tightened, the opening of the flexible silicone sleeve fits tightly against the rod-shaped structure of the hearing aid to prevent moisture and dust from entering the main body of the hearing aid.

[0010] In one embodiment of this application, the flexible silicone sleeve covering the microphone and speaker of the hearing aid has a sound-transmitting protective structure so that the sound pickup and output functions of the hearing aid are not affected.

[0011] In one embodiment of this application, the retraction component further includes an elastic pressing structure, one end of the rope is fixedly connected to the elastic pressing structure, and the other end is movably connected to the elastic pressing structure;

[0012] When the elastic pressing structure is pressed, the rope relaxes, making the tightness of the bag opening of the flexible silicone sleeve adjustable.

[0013] When the elastic pressing structure is released, the rope tightens to secure the rope on the elastic pressing structure.

[0014] In one embodiment of this application, the elastic pressing structure includes:

[0015] A connector is fixedly connected to the flexible silicone sleeve. The connector has a first positioning groove, a second positioning groove, and a first connecting hole. The first positioning groove is connected to the first connecting hole, and the second positioning groove is connected to the first connecting hole.

[0016] The pressing component has a second connecting hole. The pressing component is located in the positioning groove, and the second connecting hole is connected to the first connecting hole. One end of the rope is fixedly connected to the elastic pressing structure, and the other end passes through the second connecting hole.

[0017] When the pressing element is pressed, the cord can slide away from the bag opening through the second connecting hole, tightening the bag opening of the flexible silicone sleeve so that the bag opening fits tightly against the rod-shaped structure of the hearing aid. Alternatively, the cord can slide towards the bag opening through the second connecting hole, loosening the bag opening of the flexible silicone sleeve.

[0018] In one embodiment of this application, the elastic pressing structure further includes a reset member, which is disposed in the second positioning groove. One end of the reset member abuts against the bottom surface of the connecting member in the second positioning groove, and the other end abuts against the pressing member.

[0019] When the pressing element is released, the reset element pushes the pressing element to reset, and the rope is fixed in the second connecting hole, so that the opening of the flexible silicone sleeve fits tightly with the rod-shaped structure of the hearing aid.

[0020] In one embodiment of this application, the end of the rope away from the bag opening is provided with a winding member, which is used to wind the end of the rope away from the bag opening onto the rod-shaped structure of the hearing aid.

[0021] In one embodiment of this application, the winding member includes an elastic member and a winding channel disposed within the elastic member. When the rod-shaped structure is disposed within the winding channel, the elastic member is attached to the rod-shaped structure of the hearing aid and elastically contracts according to the shape of the rod-shaped structure.

[0022] In one embodiment of this application, the winding member includes a support portion, which is fixedly connected to one end of the elastic member, and the support portion is used to support the winding state of the rope.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] The waterproof and dustproof hearing aid protective case includes a flexible silicone sleeve and a shrink-fit component. The flexible silicone sleeve has a receiving groove and an opening communicating with the receiving groove. The main body of the hearing aid is placed in the receiving groove through the opening, and the hearing aid's rod-like structure passes through the opening. The shrink-fit component includes a cord that wraps around the opening of the flexible silicone sleeve. When the cord is tightened, the opening of the flexible silicone sleeve fits tightly against the hearing aid's rod-like structure, preventing moisture and dust from entering the hearing aid's main body. This combined design of the flexible silicone sleeve and shrink-fit component achieves continuous sealing protection for the hearing aid's main body, making it particularly suitable for humid, dusty, or other special environments, thus significantly improving the hearing aid's lifespan and performance stability.

[0039] Please refer to Figures 1 to 4 This application proposes a waterproof and dustproof hearing aid protective cover 10, including a flexible silicone sleeve 100 and a shrinkable assembly 200. The flexible silicone sleeve 100 has an accommodating groove 110 and a pocket opening 120 communicating with the accommodating groove 110. The main body 41 of the hearing aid 40 is disposed in the accommodating groove 110 through the pocket opening 120, and the rod-shaped structure 42 of the hearing aid 40 passes through the pocket opening 120. The shrinkable assembly 200 includes a rope 210, which wraps around the pocket opening 120 of the flexible silicone sleeve 100. When the rope 210 is tightened, the pocket opening 120 of the flexible silicone sleeve 100 is tightly fitted with the rod-shaped structure 42 of the hearing aid 40 to prevent moisture and dust from entering the main body 41 of the hearing aid 40.

[0040] Specifically, the hearing aid 40 includes a main body 41, a rod-shaped structure 42, and an earplug 43. One end of the rod-shaped structure 42 is connected to the main body 41, and the other end is connected to the earplug 43. The flexible silicone sleeve 100 has a receiving groove 110 and a pocket opening 120 that communicates with the receiving groove 110. The main body 41 of the hearing aid 40 is placed in the receiving groove 110 through the pocket opening 120, while the rod-shaped structure 42 of the hearing aid 40 passes through the pocket opening 120. The flexible silicone sleeve 100 is made of soft silicone material, which not only fits tightly to the surface of the hearing aid 40 body 41, but also has good waterproof and dustproof performance, effectively preventing external moisture and dust from intruding into the hearing aid 40 and improving the sealing at the opening 120. The shrinking component 200 includes a cord 210 that wraps around the opening 120 of the flexible silicone sleeve 100. One end of the cord 210 is fixed to the flexible silicone sleeve 100, and the other end adjusts the tightness of the opening 120 through an adjustable shrinking structure. When the cord 210 is tightened, the opening 120 fits tightly with the rod-shaped structure 42 of the hearing aid 40, forming a reliable seal. When the cord 210 is loosened, the user can easily install or remove the hearing aid 40 body 41. Through the full coverage of the flexible silicone sleeve 100 and the adjustable sealing design at the opening 120, this protective sleeve structurally achieves comprehensive protection for the hearing aid 40 body 41, while also adapting to various structural shapes of hearing aids 40.

[0041] It is worth noting that the flexible silicone sleeve 100 is preferably a silicone rubber composite material or silicone coated with a hydrophobic film.

[0042] It should be noted that traditional protective covers cannot provide a sealed protection for the hearing aid 40 during use, and their static design makes it difficult to adapt to various hearing aid 40 models. The design of combining the flexible silicone sleeve 100 and the shrinkable component 200 in this embodiment ensures the sealing of the hearing aid 40 body 41 on the one hand, and provides flexible adaptation to the structure of the hearing aid 40 on the other hand, avoiding the shortcomings of traditional solutions in terms of practicality and protective performance.

[0043] In summary, the combined design of the flexible silicone sleeve 100 and the retractable assembly 200 achieves continuous sealing protection for the main body 41 of the hearing aid 40, making it particularly suitable for humid, dusty, or other special environments, thereby significantly improving the lifespan and performance stability of the hearing aid 40. The adjustable design of the cord 210 retractable assembly 200 at the opening 120 not only enhances the sealing effect but also provides ease of operation and structural flexibility, adapting to different sizes and shapes of the hearing aid 40's rod-shaped structure 42. The overall solution ensures a tight seal while also considering user convenience and practical application needs, representing an innovative design that combines efficient protection with ease of use.

[0044] Please refer to Figure 1In one embodiment, the flexible silicone sleeve 100 has a sound-transmitting protective structure 130 covering the microphone 411 and speaker 412 of the hearing aid 40 so that the sound pickup and output functions of the hearing aid 40 are not affected.

[0045] Specifically, the flexible silicone sleeve 100 provides a sound-permeable protective structure 130 in the area covering the microphone 411 and speaker 412 of the hearing aid 40. The sound-permeable protective structure 130 can be in the form of a waterproof sound-permeable membrane or a hydrophobic coating, allowing sound to pass through smoothly while blocking the intrusion of moisture and dust. The material and thickness of the sound-permeable protective structure 130 are optimized to ensure that sound signal pickup and output are not affected, while providing reliable protective performance.

[0046] Please refer to Figure 1 and Figure 2 In one embodiment, the shrinking assembly 200 further includes an elastic pressing structure (not shown in the figure), one end of the rope 210 is fixedly connected to the elastic pressing structure, and the other end is movably connected to the elastic pressing structure; when the elastic pressing structure is pressed, the rope 210 relaxes, so that the position of the bag opening 120 of the flexible silicone sleeve 100 is adjustable; when the elastic pressing structure is released, the rope 210 tightens, so that the rope 210 on the elastic pressing structure is fixed.

[0047] Specifically, the elastic pressing structure is used to adjust the tension of the cord 210. One end of the cord 210 is fixedly connected to the elastic pressing structure, and the other end is movably connected. When the user presses the elastic pressing structure, the cord 210 can be pulled to loosen the opening 120 of the flexible silicone sleeve 100, making it easier to insert or remove the hearing aid 40 body 41 into or from the receiving groove 110. The cord 210 can also be pulled in the opposite direction to tighten the opening 120 of the flexible silicone sleeve 100, making the opening 120 fit tightly against the rod-shaped structure 42 of the hearing aid 40. At this time, the pressing structure can be released, and the elastic device pushes the cord 210 to tighten, making the cord 210 unable to move, so that the opening 120 fits tightly against the rod-shaped structure 42 of the hearing aid 40, forming an efficient seal.

[0048] Please refer to Figure 4In one embodiment, the elastic pressing structure includes a connector 220 and a pressing member 230. The connector 220 is fixedly connected to the flexible silicone sleeve 100. The connector 220 has a first positioning groove 221, a second positioning groove 222, and a first communicating hole (not shown in the figure). The first positioning groove 221 communicates with the first communicating hole, and the second positioning groove 222 communicates with the first communicating hole. The pressing member 230 has a second communicating hole 231. The pressing member 230 is disposed in the positioning groove, and the second communicating hole 231 communicates with the first communicating hole. One end of 210 is fixedly connected to the elastic pressing structure, and the other end passes through the second connecting hole 231. When the pressing member 230 is pressed, the rope 210 can slide away from the bag opening 120 through the second connecting hole 231, so that the bag opening 120 of the flexible silicone sleeve 100 is tightened and the bag opening 120 of the flexible silicone sleeve 100 is tightly fitted with the rod-shaped structure 42 of the hearing aid 40. Alternatively, the rope 210 can slide towards the bag opening 120 through the second connecting hole 231, so that the bag opening 120 of the flexible silicone sleeve 100 is relaxed.

[0049] Specifically, the connector 220 is fixedly connected to the flexible silicone sleeve 100, and the connector 220 has a first positioning groove 221, a second positioning groove 222, and a first connecting hole. The first positioning groove 221 and the second positioning groove 222 are respectively connected to the first connecting hole. The pressing member 230 has a second connecting hole 231, and the pressing member 230 is installed in the first positioning groove 221 of the connector 220, and the second connecting hole 231 is connected to the first connecting hole. One end of the rope 210 is fixedly connected to the elastic pressing structure, and the other end passes through the second connecting hole 231. When the user presses the pressing member 230, the rope 210 slides away from the opening 120 through the second connecting hole 231, causing the opening 120 of the flexible silicone sleeve 100 to tighten, thereby making the opening 120 fit tightly against the rod-shaped structure 42 of the hearing aid 40, providing effective sealing protection. Conversely, when the pressing member 230 is released, the rope 210 slides towards the opening 120 through the second connecting hole 231, loosening the opening 120 of the flexible silicone sleeve 100, making it easier to put or take out the hearing aid body 41 into the receiving slot 110.

[0050] In summary, by combining the pressing element 230 with the connecting hole, the cord 210 can be flexibly adjusted, allowing the opening 120 to be easily tightened or loosened, thus providing precise waterproof and dustproof protection for the hearing aid 40 body 41. In the tightened state, the opening 120 fits tightly against the rod-shaped structure 42 of the hearing aid 40, effectively preventing the intrusion of external moisture and dust; in the loosened state, the opening 120 is open, allowing the user to easily attach and detach the hearing aid 40.

[0051] Please refer to Figure 4In one embodiment, the elastic pressing structure further includes a reset member 240, which is disposed in the second positioning groove 222. One end of the reset member 240 abuts against the bottom surface of the connector 220 in the second positioning groove 222, and the other end abuts against the pressing member 230. When the pressing member 230 is released, the reset member 240 pushes the pressing member 230 to reset, and the rope 210 is fixed in the second connecting hole 231, so that the opening 120 of the flexible silicone sleeve 100 is tightly fitted with the rod-shaped structure 42 of the hearing aid 40.

[0052] Specifically, the reset member 240 is disposed within the second positioning groove 222, with one end abutting against the bottom surface of the connector 220 and the other end abutting against the bottom of the pressing member 230. The function of the reset member 240 is to push the pressing member 230 back to its initial position using its elastic restoring force when the pressing member 230 is released, and to fix the rope 210 within the second connecting hole 231 during this process. That is, after the pressing member 230 returns to its initial position, the rope 210 is fixed within the second connecting hole 231 by the misalignment between the first connecting hole of the connector 220 and the second connecting hole 231 of the pressing member 230. At this time, the opening 120 of the flexible silicone sleeve 100 will fit tightly against the rod-shaped structure 42 of the hearing aid 40, thereby ensuring the sealing of the opening 120 and preventing moisture and dust from entering the main body 41 of the hearing aid 40.

[0053] Please refer to Figure 1 and Figure 2 In one embodiment, the end of the rope 210 away from the bag opening 120 is provided with a winding member 300. The winding member 300 is used to wind the end of the rope 210 away from the bag opening 120 onto the rod-shaped structure 42 of the hearing aid 40. The winding member 300 includes an elastic member 310 and a winding channel 320. When the rod-shaped structure 42 is disposed in the winding channel 320, the elastic member 310 is attached to the rod-shaped structure 42 of the hearing aid 40 and elastically contracts according to the shape of the rod-shaped structure 42.

[0054] Specifically, the winding member 300 is used to wind the end portion of the cord 210 onto the rod-shaped structure 42 of the hearing aid 40. The winding channel 320 is an annular or semi-closed structure opened inside the winding member 300, and the elastic member 310, similar to the winding cord of a telephone, is used to accommodate the rod-shaped structure 42 of the hearing aid 40. When the rod-shaped structure 42 is inserted into the winding channel 320, the elastic member 310 fits tightly against the surface of the rod-shaped structure 42 and elastically contracts according to its shape. The elastic member 310 is usually made of a highly elastic material, which can adapt to rod-shaped structures 42 of different shapes and sizes, achieving a tight fit while maintaining a certain tension to stabilize the position of the cord 210.

[0055] Please refer to Figure 1 and Figure 2In one embodiment, the winding member 300 includes a support portion 330, which is fixedly connected to one end of the elastic member 310. The support portion 330 is used to support the winding state of the rope 210.

[0056] Specifically, the support portion 330 is fixedly connected to one end of the elastic element 310 to provide support for the winding state of the rope 210. The support portion 330 can be designed as a ring, semi-ring, or other adaptable structure, located outside or inside the winding channel 320. Its function is to stabilize the position of the elastic element 310 and provide a fixed support point for the winding of the rope 210, preventing the rope 210 from slipping or slack during winding. Through the design of the support portion 330, the overall structure of the winding component 300 is more robust, and the stability of the wound rope 210 is significantly improved.

[0057] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
