Description

Technical Field

[0001] This utility model relates to the technical field of hearing aids, and in particular to a wearing structure for RIC module hearing aids. Background Technology

[0002] A hearing aid is a sophisticated electronic device whose main function is to amplify sound, helping people with hearing loss to hear more clearly and easily. It cannot cure hearing loss, but it can greatly improve communication skills and quality of life.

[0003] RIC hearing aids are generally divided into two parts: the main unit and the receiver. The receiver is usually worn in the ear canal through an earplug. Because some earplugs almost completely block the ear canal in order to isolate external sounds, users often feel uncomfortable when wearing hearing aids for a long time. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide a wearing structure for RIC module hearing aids, which, while ensuring the effect of the earplug isolating external sound, allows the user's ear canal to continuously exchange gas with the outside world, thus avoiding discomfort caused by prolonged wearing of the hearing aid.

[0005] To solve the above problems, this utility model provides a wearing structure for a RIC module hearing aid, including: a receiver, which is fitted with a fixing tube on its outer periphery. The fixing tube has a plurality of circular holes arranged in a circular array inside its tube wall, and a one-way valve is fixedly installed in the openings at both ends of the circular holes. The piston-injection mechanism is located on the inner wall of the fixed tube at the position corresponding to the circular hole. It is used in conjunction with the one-way valve to draw external gas into the circular hole and push the gas in the circular hole into the ear canal. A filter element, which is installed in a corresponding circular hole, is used to filter the gas flowing into the circular hole.

[0006] Preferably, a sponge sleeve is fixedly fitted on the outer periphery of the receiver, and the outer peripheral wall of the sponge sleeve is in contact with the inner wall of the fixing tube.

[0007] Preferably, a silicone sleeve is fixedly fitted on the outer peripheral wall of the fixing tube. The silicone sleeve is frustum-shaped, and the outer circumference edges at both ends of the silicone sleeve are arc-shaped.

[0008] Preferably, the piston air injection mechanism includes a plurality of piston holes, which are equally spaced at the positions of the corresponding circular holes on the inner wall of the fixed tube, and the interior of the piston holes is connected to the interior of the corresponding circular holes. A piston push rod is slidably installed in the piston hole, and one end of the piston push rod is hemispherical and passes through the sponge sleeve to contact the outer wall of the receiver. The other end of the piston push rod is fixedly connected to the inner wall of the corresponding circular hole by a spring.

[0009] Preferably, the filter element includes a filter block disposed in the corresponding opening of the corresponding circular hole, one end of the filter block is in contact with the air inlet end of the corresponding one-way valve, and the other end of the filter block is an arc-shaped surface that bulges from all sides toward the center.

[0010] Preferably, a threaded tube is fixedly sleeved on the outer periphery of the filter block, and the outer periphery wall of the threaded tube is threadedly connected to the inner wall of the corresponding circular hole.

[0011] This utility model has the following beneficial effects: When in use, the improved hearing aid's wearing structure uses the vibration of the receiver as a driving force to activate the piston inflation mechanism. This mechanism, in conjunction with a one-way valve, slowly draws in external air and pushes it into the ear canal. Simultaneously, a filter prevents dust and other impurities from being trapped outside the ear canal. This ensures that the earplug effectively isolates external sound while allowing continuous gas exchange between the user's ear canal and the outside environment, preventing discomfort caused by prolonged hearing aid use.

[0015] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Example: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention discloses a wearing structure for a hearing aid with an RIC module, comprising: a receiver 1, a fixing tube 2 sleeved on its outer periphery, and a plurality of circular holes 3 arranged in a circular array inside the tube wall of the fixing tube 2, and a one-way valve 4 fixedly installed in the openings at both ends of the circular holes 3. The piston injection mechanism 5 is located on the inner wall of the fixed tube 2 at the position corresponding to the round hole 3. It is used to cooperate with the one-way valve 4 to draw external gas into the round hole 3 and push the gas in the round hole 3 into the ear canal. The filter element 6 is disposed in the corresponding circular hole 3 and is used to filter the gas flowing into the circular hole 3.

[0017] In this embodiment, when the improved hearing aid is in use, the vibration of the receiver 1 is used as the driving force to drive the piston air injection mechanism 5 to start. This works in conjunction with the one-way valve 4 to slowly draw in external gas and push the gas into the ear canal. At the same time, the filter 6 blocks dust and other objects carried in the external gas from the round hole 3. While ensuring the earplug's ability to isolate external sound, the user's ear canal continues to exchange gas with the outside world, thus avoiding discomfort caused by prolonged wearing of the hearing aid. Specifically: (Please refer to...) Figure 1 As shown, receiver 1 is connected to the main unit via a thin wire. According to the existing installation method of the main unit, the main unit is fixed by ear clip or worn behind the user's ear by hook, while receiver 1 is inserted into the ear canal to complete the wearing. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, during the use of this improved hearing aid's wearing structure, as the receiver 1 emits a sound, the receiver 1 vibrates accordingly. The vibrating receiver 1 will shift to one side, thereby pressing the piston air injection mechanism 5 through the receiver 1, driving the piston air injection mechanism 5 to operate, repeatedly expanding or shrinking the internal space of the corresponding circular hole 3, thereby drawing in external air through the one-way valve 4 at one end of the fixed tube 2, and injecting part of the gas in the circular hole 3 into the ear canal through the one-way valve 4 at the other end of the fixed tube 2.

[0018] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 5 As shown, a sponge sleeve 7 is fixedly sleeved on the outer periphery of the receiver 1, and the outer periphery of the sponge sleeve 7 is in contact with the inner wall of the fixing tube 2. In this embodiment, please refer to Figure 2 and Figure 5 As shown, the sponge sleeve 7 can stably connect the fixing tube 2 and the receiver 1 without affecting the vibration of the internal receiver 1, so that the fixing tube 2 is always fitted on the outer periphery of the receiver 1, and the holes on the sponge sleeve 7 can allow excess air in the ear canal to be discharged from the ear canal.

[0019] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a silicone sleeve 8 is fixedly sleeved on the outer peripheral wall of the fixed tube 2. The silicone sleeve 8 is frustum shaped and the outer ring edges at both ends of the silicone sleeve 8 are arc-shaped. In this embodiment, please refer to Figure 2 and Figure 5 As shown, the silicone sleeve 8 can replace the fixing tube 2 in contact with the inner wall of the ear canal, avoiding the fixing tube 2 being too hard and coming into contact with the inner wall of the ear canal, which would cause discomfort to the user. The silicone sleeve 8, the foam sleeve 7, and the fixing tube 2 form a complete earplug, thereby fixing or wearing the receiver 1 in the user's ear canal in the manner of existing earplugs. The earplug as a whole has only a very small gap structure on the foam sleeve 7, which can greatly isolate external sound.

[0020] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 5 As shown, the piston injection mechanism 5 includes several piston holes 51, which are equally spaced on the inner wall of the fixed tube 2 at positions corresponding to the circular holes 3. The interior of the piston holes 51 is connected to the interior of the corresponding circular holes 3. A piston push rod 52 is slidably installed in the piston holes 51. One end of the piston push rod 52 is hemispherical and passes through the sponge sleeve 7 to contact the outer wall of the receiver 1. The other end of the piston push rod 52 is fixedly connected to the inner wall of the corresponding circular hole 3 by a spring 53. In this embodiment, please refer to Figure 2 , Figure 3 and Figure 5As shown, the receiver 1 pushes the piston rod 52, and the spring 53 pushes the piston rod 52 in the opposite direction, repeatedly expanding and shrinking the internal space of the corresponding circular hole 3 and piston hole 51. This creates a pressure difference between the inside and outside of the circular hole 3. When the space inside the circular hole 3 and piston hole 51 expands, external gas is drawn into the circular hole 3 through the one-way valve 4 at one end of the fixed tube 2. When the space inside the circular hole 3 and piston hole 51 shrinks, the gas in the circular hole 3 is injected into the ear canal through the one-way valve 4 at the other end of the fixed tube 2. In summary, when the receiver 1 vibrates, it can draw in external gas very slowly and inject the gas into the ear canal. The operation of the device does not require an additional power source and will not affect the operating time of the hearing aid. Specifically, when receiver 1 shifts to one side, part of the piston push rod 52 at the corresponding position is pushed into piston hole 51. At this time, the overall space inside the corresponding circular hole 3 and piston hole 51 shrinks. At the same time, due to the push of spring 53, part of the piston rod at the corresponding position slides out of piston groove. At this time, the overall space inside the corresponding circular hole 3 and piston hole 51 expands.

[0021] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the filter element 6 includes a filter block 61, which is disposed in the corresponding opening of the corresponding circular hole 3. One end of the filter block 61 is in contact with the air inlet end of the corresponding one-way valve 4, and the other end of the filter block 61 is an arc-shaped surface that protrudes from all sides toward the center. In this embodiment, please refer to Figure 2 , Figure 3 and Figure 4 As shown, before the outside air flows into the round hole 3 through the one-way valve 4, it needs to pass through the filter holes of the filter block 61, so that the filter block 61 can block dust and particulate matter and other impurities in the outside air from the round hole 3.

[0022] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, a threaded tube 62 is fixedly sleeved on the outer periphery of the filter block 61, and the outer periphery of the threaded tube 62 is threadedly connected to the inner wall of the corresponding circular hole 3. In this embodiment, please refer to Figure 2 , Figure 3 and Figure 4 As shown, the threaded tube 62 allows the filter block 61 to be disassembled and installed, making it convenient to clean and replace the filter block 61. Specifically, the user places their finger on the filter block 61. Due to the high friction between the finger and the filter block 61 caused by the filter holes on the filter block 61, the user can twist the threaded tube 62 by twisting the finger, thereby unscrewing the threaded tube 62 out of the round hole 3 to complete the disassembly of the filter block 61. After the filter block 61 is cleaned, the threaded tube 62 is screwed back into the round hole 3 as described above to complete the disassembly and assembly of the filter block 61.

[0023] Working principle: When using the improved hearing aid wearing structure, the main unit is fixed by ear clip or worn behind the user's ear by hook, while the receiver 1 is inserted into the ear canal. The receiver 1 is fixed in the ear canal by the friction between the silicone sleeve 8 and the inner wall of the ear canal, so as to complete the wearing of the receiver 1. During the use of the hearing aid wearing structure, as the receiver 1 emits a sound, the receiver 1 vibrates accordingly. The piston rod 52 is pushed by the receiver 1 and pushed in the opposite direction by the spring 53, which expands and contracts the overall space inside the corresponding round hole 3 and piston hole 51. This creates a pressure difference between the inside and outside of the round hole 3. Through the one-way valves 4 at both ends of the fixed tube 2, the external air is slowly drawn in and injected into the ear canal. At the same time, the filter block 61 blocks impurities in the air from outside the round hole 3.

[0024] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
