This hearing aid helps people with hearing loss better understand and participate in daily conversations by capturing, amplifying and processing sounds in the environment, thereby improving their social skills and quality of life. Existing ear-band hearing aids have made significant progress after development, but there are still some defects. That is, during use, since the hearing aid is directly inserted into the user's ear canal, the user's ear canal will inevitably secrete grease. Therefore, when people use hearing aids, as the use time increases, the mixture of grease, dust, etc. will inevitably block the sound outlet of the hearing aid, which will cause the sound enhancement effect of the hearing aid to deteriorate, affecting the user's experience.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 16 As shown, the present invention provides the following technical solutions:

[0040] Implementation Method 1

[0041] This embodiment provides an in-ear hearing aid. When using the hearing aid, the user needs to insert the hearing aid into his / her ear canal. The ear canal will secrete oil and dust during use. Therefore, impurities will inevitably stick to the hearing aid, which will affect the use effect. Therefore, the hearing aid needs to be cleaned regularly, such as Figure 1-Figure 4 As shown, the hearing aid mainly includes a housing 3 and a hearing aid component 5;

[0042] A placement cavity 35 is formed inside the shell 3 for accommodating the hearing aid 5, and a material guide 1 is fixedly connected to the bottom of the shell 3. A bottom cavity 13 is formed inside the material guide 1. The bottom cavity 13 is connected to the placement cavity 35 and is used to accommodate and guide out impurities scraped off the hearing aid 5.

[0043] In addition, in the present invention, if Figure 15-16As shown, the hearing aid device 5 includes a hearing aid body 51, and the hearing aid body 51 is recessed on one side toward the guide member 1 to form a sound outlet hole 59 for outputting sound; and the other side is recessed to form a sound pickup hole 52 for receiving sound;

[0044] Furthermore, in the present invention, in order to clean the sound outlet hole 59 and prevent impurities from clogging the sound outlet hole 59, as shown in FIG. Figure 5 As shown, inside the material guiding channel, there is a connecting shaft 16 rotatably connected perpendicularly to the horizontal plane, and a scraping portion is fixedly connected to the top of the connecting shaft 16. The scraping portion is located inside the placement cavity 35 and is used to scrape the sound hole 59 to remove impurities thereon. In order to drive the connecting shaft 16 to rotate, a motor 15 is fixedly connected inside the material guiding member 1, and the output end of the motor 15 is connected to the connecting shaft 16.

[0045] Through the above technical solution, when a person needs to use a hearing aid, the user wears the hearing aid body 51 in the ear canal, and when wearing it, it is necessary to ensure that the sound pickup hole 52 and the sound outlet hole 59 of the hearing aid body 51 are respectively aligned with the ear canal opening and the eardrum direction. When the person completes wearing the hearing aid body 51, the hearing aid body 51 works, so that the sound pickup hole 52 on the hearing aid body 51 receives the surrounding sound and converts the sound into an electric current signal, which is then amplified and converted into a sound signal, and the sound is played through the sound outlet hole 59, thereby assisting the user. When the person needs to clean the ear, When the sound outlet hole 59 is opened, as the use time increases, if impurities such as grease adhere to the sound outlet hole 59 and affect the sound effect, the hearing aid body 51 is taken out of the user's ear canal and placed in the placement cavity 35 on the shell part 3. After the hearing aid body 51 is placed, the motor 15 is started, and the motor 15 drives the connecting shaft 16 to rotate. As the connecting shaft 16 rotates, the scraping part is driven to rotate, and the scraping part starts to scrape the sound outlet hole 59, scraping off the earwax, dust and other impurities attached thereon. The scraped impurities enter the interior of the guide member 1 through the bottom cavity 13 for collection.

[0046] Implementation Method 2

[0047] This embodiment further optimizes the wearing method of the hearing aid body 51 on the basis of Embodiments 1 to 7.

[0048] Specifically, in the present invention, Figure 3 , Fig.15 and Fig.16 As shown, a side hole 54 is formed inwardly on one side of the hearing aid body 51, and the side hole 54 is located on one side of the sound pickup hole 52. A deformable limiting plate 55 is fixedly connected inside the side hole 54, and a detachable connecting ring 56 is sleeved on the limiting plate 55. A transparent elastic rope 57 is fixedly connected to one side of the connecting ring 56, and a transparent elastic ring 58 is fixedly connected to the free end of the transparent elastic rope 57.

[0049] In this embodiment, before a person needs to wear the hearing aid body 51, the hearing aid body 51 is taken out from the placement cavity 35, and the limiting plate 55 is pulled so that the limiting plate 55 is bent and unfolded, and then the connecting ring 56 is sleeved on the limiting plate 55, so that the transparent elastic rope 57 and the transparent elastic ring 58 are installed on one side of the hearing aid body 51, and then the hearing aid body 51 is inserted into the user's ear canal, and the transparent elastic ring 58 is pulled so that the transparent elastic ring 58 is sleeved on the user's own ear. When the person uses the hearing aid body 51, the hearing aid body 51 will not be lost through the cooperation of the transparent elastic ring 58 and the transparent elastic rope 57.

[0050] Implementation Method 3

[0051] When impurities accumulate to a certain extent, it is necessary to collect and process the impurities generated during cleaning. Therefore, in the present invention, Figure 5-Figure 6 As shown, on one side of the material guide member 1, a drain groove 19 is opened to form, and the drain groove 19 is connected to the bottom cavity 13 for draining out impurities. A material guide slope 12 is formed at the bottom of the bottom cavity 13. The horizontal height of the material guide slope 12 close to the drain groove 19 is lower than the horizontal height on the other side, so that impurities can slide smoothly into the drain groove 19 along the material guide slope 12. The user can discharge the impurities from the drain groove 19 by operating the drain groove 19 on the material guide member 1.

[0052] In this embodiment, regarding the wearing of the hearing aid, the wearing method is the same as that in the first embodiment, so it is not repeated here. The hearing aid body 51 is taken out from the user's ear canal and placed in the placement cavity 35 on the shell member 3. After the hearing aid body 51 is placed, the motor 15 is started, and the motor 15 drives the connecting shaft 16 to rotate. As the connecting shaft 16 rotates, the scraping part is driven to rotate. The scraping part begins to scrape the sound hole 59, and scrapes off the earwax, dust and other impurities attached thereto. The scraped impurities enter the interior of the guide member 1 through the bottom cavity 13 for collection. After the scraping part scrapes off the impurities, the impurities slide into the drain trough 19 along the guide slope 12. When the impurities accumulate to a certain extent, the impurities are removed through the drain trough 19, and the impurities can be discharged more smoothly through the guide slope 12.

[0053] Implementation Method 4

[0054] On the basis of the third embodiment, in order to collect the impurities discharged from the sewage tank 19, the impurities can be easily processed in a centralized manner, such as Figure 1-Figure 4 As shown, a detachable storage member 4 is added to temporarily store scraped impurities, so that the user can clean it at any time;

[0055] Specifically, a detachable material storage member 4 is provided on one side of the material guide member 1. The material storage member 4 includes a material collection shell 41. A cavity for storing dirt is formed inside the material collection shell 41. The material collection shell 41 is open toward one side of the cavity to form a feed trough 44. The feed trough 44 is connected to the sewage trough 19 to receive impurities discharged from the sewage trough 19.

[0056] In addition, two second magnetic plates 47 are symmetrically fixedly connected to one side of the collection shell 41, the feed trough 44 is located between the two second magnetic plates 47, and two first magnetic plates 110 are symmetrically fixedly connected to one side of the material guide member 1, the sewage trough 19 is located between the two first magnetic plates 110, and the first magnetic plate 110 matches the second magnetic plate 47 and is connected together by magnetic force, so that the material storage member 4 can be easily disassembled and installed.

[0057] In this embodiment, regarding the wearing of the hearing aid, the wearing method is the same as that of the first embodiment, so it is not repeated here. When the hearing aid body 51 is placed in the placement cavity 35, the motor 15 is started, and the motor 15 drives the connecting shaft 16 to rotate. As the connecting shaft 16 rotates, the scraping part is driven to rotate, and the scraping part begins to scrape the sound hole 59, scraping off the earwax, dust and other impurities attached thereto. The scraped impurities enter the interior of the guide member 1 through the bottom cavity 13 for collection. After the scraping part scrapes off the impurities, the impurities slide into the drain trough 19 along the guide slope 12. When the impurities accumulate to a certain extent, When the impurities are discharged through the drain chute 19, and the impurities can be discharged more smoothly through the material guide slope 12, the impurities slide into the drain chute 19 along the material guide slope 12, and then enter the cavity of the aggregate shell 41. When the impurities in the aggregate shell 41 accumulate to a certain extent, the user pulls the aggregate shell 41 to separate the first magnetic plate 110 and the second magnetic plate 47, so that the storage piece 4 can be removed from the material guide piece 1, and then the impurities can be poured out from the aggregate shell 41. After cleaning the impurities, the user can reinstall the storage piece 4 on the material guide piece 1 and connect the first magnetic plate 110 and the second magnetic plate 47 by magnetic force.

[0058] Implementation Method 5

[0059] On the basis of the fourth embodiment, in order to improve the efficiency of impurities entering the aggregate shell 41, in the present invention, as Figure 1-Figure 6 , Figure 12-14 As shown, the structure of the material storage member 4 is further optimized, a negative pressure cleaning function is added, and the cleaning efficiency of impurities is improved.

[0060] Specifically, in the present invention, an inclined plate 45 is fixedly connected to the inner bottom end of the aggregate shell 41, and the horizontal height of the inclined plate 45 on one side close to the feed trough 44 is lower than that on the other side, so that impurities can slide smoothly to the bottom of the aggregate shell 41 along the inclined plate 45, and a connecting pipe 42 is fixedly connected to the top of the aggregate shell 41, and a detachable negative pressure member 2 is screwed and connected to the top of the connecting pipe 42. A gap for impurities to pass through is formed between the top of the inclined plate 45 and the inner wall of the aggregate shell 41, and since impurities can only pass through the gap, after being sucked to the other side of the inclined plate 45, the impurities will not fall back to the side of the inclined plate 45 close to the feed trough 44, so that the impurities can smoothly enter the suction range of the negative pressure member 2, and the side of the aggregate shell 41 away from the feed trough 44 is open to form a discharge hole 46, and a baffle 43 for covering the discharge hole 46 is rotatably connected to one side of the aggregate shell 41. When it is necessary to clean the impurities, the user can open the baffle 43 so that the impurities can be discharged from the discharge hole 46 .

[0061] In this embodiment, the wearing method of the hearing aid is the same as that of embodiment 1, so it is not repeated here. The motor 15 drives the connecting shaft 16 to rotate, so that the connecting shaft 16 drives the scraping part to rotate and starts to scrape the sound outlet hole 59. After the scraping part scrapes off the impurities, the impurities slide into the drain trough 19 along the guide slope 12, and then enter the cavity of the aggregate shell 41. When the impurities are cleaned, the negative pressure piece 2 is started to create negative pressure inside the aggregate shell 41, so that the feed trough 44 generates suction, so that the impurities can be sucked into the feed trough 44 faster, and under the action of negative pressure, the impurities are sucked into the aggregate shell 41 along the inclined plate 45 and the gap. When the cleaning is completed, the negative pressure piece 2 is closed, the negative pressure cleaning is stopped, and the baffle 43 is opened to clean the impurities, so that the impurities can be discharged from the outlet hole 46. If it is necessary to continue using the storage piece 4 to collect impurities, the user can reinstall the aggregate shell 41 on the guide piece 1.

[0062] Implementation Method 6

[0063] Regarding how the negative pressure member 2 works, Figure 1-Figure 3 , Figure 7 As shown, the negative pressure member 2 includes a vacuum pump 21, the air inlet end and the air outlet end of the vacuum pump 21 are respectively fixedly connected to an air inlet pipe 23 and an air outlet pipe 22, a filter is installed inside the air inlet pipe 23, and the free end of the air inlet pipe 23 is rotatably connected to a connector 24, which is rotatably connected to the connecting pipe 42, so that the negative pressure member 2 can be rotated at a certain angle relative to the aggregate shell 41, which is convenient for user operation.

[0064] In this embodiment, before the device is used, the connector 24 is connected to the connecting pipe 42. When the impurities in the aggregate shell 41 accumulate to a certain extent, the vacuum pump 21 is started to allow the air inlet pipe 23 to extract gas and discharge the gas through the air outlet pipe 22, thereby creating a negative pressure inside the aggregate shell 41, thereby allowing the feed trough 44 to generate suction, so that the impurities can be sucked into the feed trough 44 more quickly, and under the action of the negative pressure, the impurities are sucked into the aggregate shell 41 along the inclined plate 45 and the gap, and the impurities are blocked by the filter net so that the gas can be discharged normally, and the impurities are retained inside the aggregate shell 41. When cleaning is completed, the negative pressure piece 2 is closed, the negative pressure cleaning is stopped, and the baffle 43 is opened to clean the impurities so that the impurities can be discharged from the discharge hole 46.

[0065] Implementation Method 7

[0066] Based on the first embodiment, the present embodiment optimizes the structure of the scraping part, thereby improving the scraping efficiency and the cleaning effect.

[0067] like Figure 5-Figure 6 As shown, the scraping part includes a conical head 17, the diameter of which gradually decreases from the top to the bottom, so that the conical head 17 can enter the sound pickup hole 52 and the sound outlet hole 59 more deeply for more thorough cleaning. A scraper 18 for scraping the sound outlet hole 59 is fixedly connected to one side of the bottom of the conical head 17. The scraper 18 can fit tightly against the inner wall of the sound outlet hole 59 to scrape off the impurities attached thereto.

[0068] In this embodiment, when a person needs to clean the sound hole 59, the user starts the motor 15, and the motor 15 drives the connecting shaft 16 to rotate, so that the connecting shaft 16 drives the cone head 17 and the scraper 18 to rotate. As the cone head 17 and the scraper 18 rotate, they begin to scrape the inner wall of the sound hole 59, scraping off earwax, dust and other impurities attached thereto, and the scraped impurities are made to enter the interior of the material guide 1 along the bottom cavity 13 through the cooperation of the cone head 17, and the vacuum pump 21 is started to extract gas from the air inlet pipe 23. And the gas is discharged through the outlet pipe 22, so that the internal negative pressure of the aggregate shell 41 is created, so that the feed trough 44 generates suction, so that impurities can be sucked into the feed trough 44 faster, and under the action of the negative pressure, the impurities are sucked into the aggregate shell 41 along the inclined plate 45 and the gap, and the impurities are blocked by the filter net, so that the gas can be discharged normally, and the impurities are retained in the aggregate shell 41. When the cleaning is completed, the negative pressure part 2 is closed, the negative pressure cleaning is stopped, and the baffle 43 is opened to clean the impurities, so that the impurities can be discharged from the discharge hole 46.

[0069] Implementation Method 8

[0070] Based on the first embodiment, this embodiment comprehensively optimizes the structures of the material guide member 1 and the housing member 3, thereby improving the overall performance of the hearing aid and the user experience.

[0071] Specifically, Figure 1-Figure 4 , Figure 8-Figure 10 As shown, the material guide member 1 includes a bottom shell 11, a bottom cavity 13 is formed inside the bottom shell 11, and a hollow inner cavity 14 is also formed inside the bottom shell 11. The inner cavity 14 is located below the bottom cavity 13 and is used to accommodate a motor 15. The output end of the motor 15 is connected to a connecting shaft 16, and the cleaning function of the scraping part is realized by driving the connecting shaft 16 to rotate;

[0072] Furthermore, in the present invention, regarding the above-mentioned housing member 3, as Figure 1-Figure 4 , Figure 9-10 As shown, the housing member 3 includes a first housing 31 and a second housing 34. A placement cavity 35 is formed between the first housing 31 and the second housing 34 for accommodating the hearing aid 5. The top of the second housing 34 is fixedly connected to the top of the bottom shell 11, thereby achieving a stable connection between the material guide member 1 and the housing member 3. A cover plate 37 for covering the top opening of the first housing 31 is rotatably connected to one side of the first housing 31. A rubber pad 38 is bonded to the side of the cover plate 37 facing the placement cavity 35 to improve the sealing performance and prevent dust and moisture from entering the placement cavity 35.

[0073] In this embodiment, when a person needs to use a hearing aid, the user wears the hearing aid body 51 in the ear canal, and when wearing it, it is necessary to ensure that the sound pickup hole 52 and the sound outlet hole 59 of the hearing aid body 51 are aligned with the ear canal opening and the eardrum direction respectively. When the person completes wearing the hearing aid body 51, the hearing aid body 51 works so that the sound pickup hole 52 on the hearing aid body 51 receives the surrounding sound and converts the sound into an electric current signal, which is then amplified and converted into a sound signal, and the sound is played through the sound outlet hole 59, thereby assisting the user. When the person needs to clean the sound outlet hole 59, the user places the hearing aid body 51 in the placement cavity 35 formed between the first shell 31 and a second shell 34. After placing the hearing aid body 51, the person closes the cover plate 37 to cover the opening at the top of the first shell 31, and starts the motor 15, so that the motor 15 drives the connecting shaft 16 to rotate, thereby The connecting shaft 16 drives the conical head 17 and the scraper 18 to rotate. As the conical head 17 and the scraper 18 rotate, they begin to scrape the inner wall of the sound outlet 59, and scrape off the earwax, dust and other impurities attached thereto. With the cooperation of the conical head 17, the scraped impurities enter the interior of the material guide 1 along the bottom cavity 13, and start the vacuum pump 21 to make the air inlet pipe 23 extract gas and discharge the gas through the air outlet pipe 22, so that the internal negative pressure of the aggregate shell 41 is generated, so that the feed trough 44 generates suction, so that impurities can be sucked into the feed trough 44 faster, and under the action of negative pressure, the impurities are sucked into the aggregate shell 41 along the inclined plate 45 and the gap, and the impurities are blocked by the filter net, so that the gas can be discharged normally, and the impurities are retained in the aggregate shell 41. When cleaning is completed, the negative pressure member 2 is closed, the negative pressure cleaning is stopped, and the baffle 43 is opened to clean the impurities, so that the impurities can be discharged from the discharge hole 46.

[0074] Implementation Method 9

[0075] Based on the eighth embodiment, this embodiment adds a cleaning function for the inner wall of the placement cavity 35 and a stable installation structure for the hearing aid device 5.

[0076] Specifically, in the present invention, Figure 8-Figure 11 As shown, a first sponge pad 36 is bonded to the inner wall of the placement cavity 35. A second sponge pad 310 is bonded to the bottom of the first sponge pad 36. The second sponge pad 310 is located inside the second shell 34, while the first sponge pad 36 is located inside the first shell 31. This design can not only clean the surface of the hearing aid body 51, but also absorb the vibration and noise generated by the hearing aid during the cleaning process.

[0077] In addition, in the present invention, if Figure 8-Figure 10As shown, a liquid injection tube 32 is fixedly connected to the first shell 31 , and the liquid injection tube 32 is connected to the placement cavity 35 . A detachable sealing cover 33 is provided on the top of the liquid injection tube 32 . The user can inject cleaning liquid or other maintenance liquid into the placement cavity 35 by opening the sealing cover 33 .

[0078] In addition, two rotating rods 39 are symmetrically connected to the first housing 31 for rotation, and the inner wall of the sound pickup hole 52 forms a limiting groove 53 matching the rotating rods 39 .

[0079] In this embodiment, after the personnel places the hearing aid body 51 in the placement cavity 35 formed between the first shell 31 and the second shell 34, the sealing cover 33 is removed, and the cleaning liquid is injected into the injection tube 32, and the cleaning liquid is guided into the interior of the first shell 31 through the injection tube 32, so that the cleaning liquid is absorbed by the first sponge pad 36 and the second sponge pad 310, and the sealing cover 33 is plugged back into the injection tube 32, and the cover plate 37 is closed so that the cover plate 37 covers the opening of the first shell 31, and the rotating rod 39 is inserted into the limiting groove 53 on the hearing aid body 51 to engage, and the rotating rod 39 is rotated, so that the rotating rod 39 drives the hearing aid body 51 to rotate in the placement cavity 35, so that the hearing aid body 51 rubs against the first sponge pad 36 and the second sponge pad 310, thereby causing the first sponge pad 36 and the second sponge pad 310 to be rubbed. The absorbed cleaning liquid cleans the surface of the hearing aid body 51, so that the device can not only clean the sound outlet 59 of the hearing aid body 51, but also clean the surface of the hearing aid body 51, thereby improving the cleaning efficiency of the hearing aid body 51. In addition, as the use time increases, the first sponge pad 36 and the second sponge pad 310 will be worn to a certain extent. Therefore, when the personnel need to replace the first sponge pad 36 and the second sponge pad 310, open the air cover 37, pull the cover 37 to open the air of the cover 37, pull the first sponge pad 36 and the second sponge pad 310, and move the worn first sponge pad 36 and the second sponge pad 310 to the outside of the placement cavity 35, and then place the unused first sponge pad 36 and the second sponge pad 310 back into the placement cavity 35, and then continue to clean the hearing aid body 51.
