Description

Technical Field

[0001] The present invention relates to an ear cleaning tool, and in particular to an ear cleaning device equipped with a camera, thereby facilitating a user to clean earwax more accurately. Background Art

[0002] Earwax is a substance secreted by the human ear canal. If earwax is secreted too much or cannot be discharged normally, it will accumulate in the ear canal, making the ear unhygienic. In severe cases, it may also cause hearing loss, tinnitus, ear pain and other symptoms.

[0003] Using an ear pick or tampon to clean earwax is difficult because the wax's location inside the ear is unknown, making it difficult to completely remove. Furthermore, improper use of the ear pick or tampon can damage the ear canal or eardrum. Using ear drops to clean earwax carries the risk of ear infection. Professional cleaning is also relatively expensive.

[0004] Currently available on the market are visual ear picks equipped with a miniature camera, allowing users to capture real-time images of their ears to assist and guide them in cleaning earwax. However, while these visual ear picks allow users to see what's happening inside the ear canal, if the camera parameters are mismatched or the lighting is insufficient, resulting in unclear images, or if the user misjudges the position of the ear pick tip used to clean earwax, the pick can scratch the ear canal and cause infection. Furthermore, the camera generates a significant amount of heat during operation. This heat, when transferred to the point where the visual ear pick contacts the ear, can cause a burning sensation and discomfort.

[0005] In addition, the visual ear pick needs to be cleaned with water before or after use. If the waterproof performance of the device is not good, it will easily cause damage to the device. When cleaning water droplets remain on the camera device, the user needs to wait for the water on the camera device to evaporate before using it, which wastes the user's time. Summary of the Invention

[0006] One advantage of the present invention is that it provides an ear cleaning device that is equipped with a suitable camera for acquiring images inside the ear in real time, so as to facilitate the user to accurately locate the location of earwax for cleaning.

[0007] Another advantage of the present invention is that it provides an ear cleaning device, which has a light source assembly configured around its camera and a light guide tube configured at the front end of the camera, so that the light from the light source assembly can be evenly guided into the ear and the end of the ear spoon assembly, and external stray light is prevented from entering the field of view of the camera, thereby reducing glare or dark spots and providing the user with a clearer image.

[0008] Another advantage of the present invention is that it provides an ear cleaning device, wherein the light-emitting surface of the light source assembly is flush with the lens end face of the camera or located behind the lens end face of the camera, so that the light of the light source assembly is effectively emitted toward the outlet of the light guide tube to illuminate the inner auditory canal and ear spoon assembly of the ear, thereby avoiding direct emission to the camera, and also avoiding the side reflection of light from the light source assembly to generate stray light emitted to the camera, and when waterproof glue is applied to the light source assembly, it also avoids the glue being applied to the lens end face and affecting the optical imaging effect.

[0009] Another advantage of the present invention is that it provides an ear cleaning device, wherein the light guide tube is used to detachably mount the ear pick assembly, and the camera does not extend into the light guide tube, thereby preventing the camera from being squeezed and damaged during the installation of the mounting portion of the ear pick assembly in the light guide tube.

[0010] Another advantage of the present invention is that it provides an ear cleaning device, wherein after the mounting portion of the ear pick is installed with the light guide tube, the connecting structure for detachably connecting the mounting portion of the ear pick assembly with the light guide tube does not form the inner wall of the light channel, thereby preventing light from being incident on the connecting structure and forming stray light incident on the camera.

[0011] Another advantage of the present invention is to provide an ear cleaning device, wherein the parameters of the camera are selected according to the length of the light guide tube and the ear pick assembly, so that the ear canal in the ear and the end of the ear pick assembly are located within the depth of field of the camera, thereby enabling the camera to obtain a clear image of the ear canal in the ear and the end of the ear pick assembly.

[0012] Another advantage of the present invention is to provide an ear cleaning device, wherein the ear pick assembly can be made of a different material from the fixing rod and can be configured to prevent heat from being transferred from the fixing rod to the end of the ear pick assembly when the camera is in operation, thereby preventing burns to the user's ears.

[0013] Another advantage of the present invention is to provide an ear cleaning device, wherein the ear spoon assembly can be constructed of a transparent material to avoid blocking the light emitted by the light source assembly.

[0014] Another advantage of the present invention is that it provides an ear cleaning device, wherein the ear spoon assembly includes a rigid inner spoon and a flexible outer spoon, wherein when the flexible outer spoon is detachably mounted on the outside of the rigid inner spoon, the center position of the flexible outer spoon end for contacting the ear and cleaning earwax is coaxial with the central axis of the camera, so that the user can accurately judge the position of the flexible outer spoon end in the image on the screen and conveniently operate the ear cleaning device to accurately clean earwax, and avoid the ear spoon assembly scratching the ear canal and causing infection.

[0015] Another advantage of the present invention is that it provides an ear cleaning device, wherein the end of the ear pick assembly, the center of the camera, and the two light-emitting elements around the camera are coplanar, thereby ensuring that the center of the end of the ear pick assembly and the earwax in the ear can be located at the center of the camera's field of view, thereby making it convenient for the user to operate the ear pick assembly to aim at the earwax for cleaning.

[0016] Another advantage of the present invention is that it provides an ear cleaning device, wherein a waterproof structure is provided at the assembly position of the camera, so that when the ear cleaning device is cleaned with water, water will not enter the interior of the ear cleaning device and cause damage to parts.

[0017] Another advantage of the present invention is that it provides an ear cleaning device, wherein a hydrophobic structure is provided in front of the camera. In this way, after the ear cleaning device is cleaned with water, water droplets are not likely to remain in front of the camera, so that the ear cleaning device can be used by the user in a timely manner without wasting the user's time.

[0089] like Figures 1 to 8 Shown in the figure is an ear cleaning device 100 according to a first preferred embodiment of the present invention, for a user to clean the ears of himself or others such as children or the elderly. In the present invention, the ear cleaning device 100 is used to clean the user's own ears as an example.

[0090] The ear cleaning device 100 includes a display device 10, an ear pick assembly 20, a fixing assembly 30, a camera 40 and a light source assembly 50, wherein the display device 10 is communicatively connected to the camera 40, so that the image inside the ear obtained by the camera 40 can be displayed on the display device 10, allowing the user to observe the situation inside the ear and obtain the location of earwax. The ear pick assembly 20 is connected to the fixing assembly 30 for cleaning earwax inside the ear. The fixing assembly 30 is connected to the display device 10. The camera 40 and the light source assembly 50 are assembled in the fixing assembly 30. The light source assembly 50 provides a fill light effect for the camera 40 to illuminate the locations inside the ear that need to be illuminated, such as the concha cavity, ear canal, etc. during the ear cleaning operation.

[0091] The display device 10 includes a display 11 and a connecting wire 12. The display 11 is integrated with an image processor for processing the image information sent by the camera 40, so that the image inside the ear captured by the camera 40 can be displayed in real time. In this way, the user does not need to connect the ear cleaning device 100 to other electronic devices, thereby facilitating the user's use.

[0092] The connecting wire 12 is used to connect the display 11 and the fixing assembly 30 . It can be understood that the connecting wire 12 includes an outer skin and an electrical connection wire wrapped in the outer skin. The electrical connection wire can be electrically connected to the camera 40 and the light source assembly 50 .

[0093] The display device 10 is also configured with a power module, which is electrically connected to the camera 40 and the light source assembly 50 via the electrical connection lines, thereby providing power to the camera 40 and the light source assembly 50. The power module may include a rechargeable battery, including but not limited to a nickel-cadmium battery, a nickel-metal hydride battery, a lead-acid battery, a lithium-ion battery, a lithium polymer battery, etc. The battery module may also be electrically connected to a mains AC power source to convert the AC power into pulsating DC power via a rectifier for use by the display 11, the camera 40, and the light source assembly 50.

[0094] The fixing assembly 30 includes a fixing rod 31 and a handle 32. The fixing rod 31 is used to assemble the camera 40 and the light source assembly 50, and the ear pick assembly 20 is connected to the fixing rod 31. The handle 32 is connected to the fixing rod 31 for the user to hold. The user can hold the handle 32 to place the front end of the ear pick assembly 20 in their ear to perform ear cleaning operations.

[0095] In this embodiment of the present invention, the fixing rod 31 is implemented as a hollow fixed cylinder, and the camera 40 and the light source assembly 50 are built into the fixing cylinder. The diameter of the fixing rod 31 is smaller than that of the handle 32, and the handle 32 has a relatively large diameter, thereby facilitating the user's grip and operation. The fixing rod 31 can be made of the same material as the handle 32 and extend integrally from the handle 32, or the fixing rod 31 and the handle 32 can be assembled and fixed, such as by bonding or using screws.

[0096] In this embodiment, the ear pick assembly 20 is detachably connected to the fixing rod 31 of the fixing assembly 30, thereby conveniently allowing the user to replace the ear pick assembly 20 with one of different sizes, allowing the user to select the ear pick assembly 20 that suits them best. In other words, the present invention can provide ear pick assemblies 20 of different sizes and styles for the user to select and assemble with the fixing rod 31. After being removed from the fixing rod 31 of the fixing assembly 30, the ear pick assembly 20 can also be cleaned separately, thereby preventing water from entering the fixing assembly 30 and damaging the camera 40 and the light source assembly 50.

[0097] like Figures 2A to 4 As shown in the figure, the ear spoon assembly 20 includes a rigid inner spoon 21 and a flexible outer spoon 22, wherein the flexible outer spoon 22 is detachably mounted on the rigid inner spoon 21. It is understood that the rigid inner spoon 21 is made of a rigid material, such as metal, metal alloy, ceramic, plastic, or wood. The flexible outer spoon 22 is made of a flexible material, such as silicone, thermoplastic polyurethane elastomer rubber (TPU), acrylonitrile-butadiene-styrene (ABS), polypropylene, polyimide, polyetherketone, polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA), ethylene and α-olefin elastomeric copolymer (POE), thermoplastic elastomer rubber (TPES), and other flexible plastics. It flexibly contacts the user's ear and thus does not scratch the user's ear.

[0098] In a preferred embodiment of the present invention, the flexible outer spoon 22 is formed by integral injection molding of a fluid material comprising an outer layer of thermoplastic polyurethane elastomer rubber and an inner layer of polycarbonate (PC), so that it can achieve a moderate hardness and softness, wherein the polycarbonate material provides a predetermined hardness and the thermoplastic polyurethane elastomer rubber ensures the softness of the flexible outer spoon 22, thereby ensuring that the flexible outer spoon 22 can prevent the ear from being scratched and causing infection while ensuring the scraping effect.

[0099] The rigid inner spoon 21 includes a mounting portion 211 and an inner spoon body 212. The inner spoon body 212 integrally extends from the mounting portion 211, and the flexible outer spoon 22 is sleeved on the inner spoon body 212. In this embodiment, the mounting portion 211 is annular, and the inner spoon body 212 integrally extends from a partial edge of the annular mounting portion 211. The mounting portion 211 is configured to be detachably assembled with the fixing rod 31.

[0100] like Figures 2A to 4As shown in , the mounting portion 211 is sleeved onto the outer surface of the fixing rod 31, thereby allowing the inner wall of the front end of the fixing rod 31 to remain smooth without requiring a structure connected to the mounting portion 211. The detachable connection between the mounting portion 211 and the fixing rod 31 can be achieved in various ways, such as a threaded connection, a snap connection, a magnetic connection, etc. Alternatively, the mounting portion 211 can be made of an elastically deformable material and can be tightly sleeved onto the front end of the fixing rod 31.

[0101] More specifically, if Figure 2A and Figure 2B As shown in the figure, the fixed rod 31 includes a rod body 311 and a light guide tube 312, the light guide tube 312 and the rod body 311 are integrally connected, and the light guide tube 312 is located in front of the camera 40 and the light source assembly 50, thereby playing the role of guiding the light emitted by the light source assembly 50.

[0102] In this embodiment, the rod body 311 can also form a cylinder, the diameter of the light guide tube 312 is smaller than the diameter of the rod body 311, the camera 40 is built into the rod body 311 without extending into the light guide tube 312, and the light guide tube 312 is also located in front of the light source assembly 50, and the light guide tube correspondingly forms a light guide wall 3121 by its inner wall, and the light guide wall 3121 forms a light guide channel 3122 and forms an opening 3123 at the front end that is connected to the light guide channel 3122, so that Part of the light from the light source assembly 50 can be directly emitted into the ear through the opening 3123, and another part of the light is reflected by the light guide wall 3121 and then guided into the ear and the end of the ear spoon assembly 20 through the light guide channel 3122 and the opening 3123. In this way, the light from the light source assembly 50 is evenly guided to the position that needs to be illuminated, and the light guide tube 312 prevents external stray light from entering the field of view of the camera 40, thereby reducing glare or dark spots and providing the user with a clearer image on the display 11.

[0103] That is to say, in this embodiment, the camera 40 and the light source assembly 50 are not arranged at positions corresponding to the opening 3123, but are located in a recessed position within the fixing rod 31 relative to the opening 3123, so that the light emitted by the light source assembly 50 can be effectively directed into the field of view of the camera 40, and the light in the external environment is prevented from directly incident on the camera 40, so that the camera 40 obtains clear image information of the field of view corresponding to the opening 3123.

[0104] In addition, in this embodiment, the light guide tube 312 is further used to be detachably connected to the mounting portion 211 of the rigid inner spoon 21. Figure 4 As shown in FIG, a portion of the inner surface 2111 of the mounting portion 211 is provided with multiple sets of positioning ridges 213 spaced apart along the circumferential direction, with a positioning groove 214 formed between two adjacent positioning ridges 213. A portion of the outer surface 3125 of the light guide tube 312 is provided with multiple sets of limiting ridges 313 spaced apart along the circumferential direction, with a limiting groove 314 formed between two adjacent limiting ridges 313. Figure 4 In the example shown in FIG, each set of positioning ridges 213 on the inner surface 2111 of the mounting portion 211 includes four positioning ridges 213 and forms three positioning grooves 214, and each set of limiting ridges 313 on the outer surface 3125 of the light guide tube 312 includes five limiting ridges 313 and forms four limiting grooves 314, respectively corresponding to the four positioning ridges 213. The positioning ridges 213 can slide in the limiting grooves 214 accordingly, and the limiting ridges 313 can slide in the positioning grooves 214 accordingly, thereby enabling the mounting portion 211 of the rigid inner spoon 21 to be detachably mounted on the outer surface 3125 of the light guide tube 312.

[0105] It can be understood that an interference fit is formed between the protrusion and the groove, so that after the mounting portion 211 of the rigid inner spoon 21 is assembled to the outer surface 3125 of the light guide tube 312, the mounting portion 211 of the rigid inner spoon 21 can be tightly positioned on the outer surface 3125 of the light guide tube 312 and is not easy to fall off, thereby preventing the ear spoon assembly 20 from falling off in the user's ear.

[0106] The limiting groove 314 has an entrance 3141 that gradually decreases in size from the opening toward the inside. The sliding end 2131 of the positioning protrusion 213 is guided by the entrance 3141 into the limiting groove 314 until the tail end 2132 of the positioning protrusion 213 reaches the entrance 3141 of the limiting groove 314. The sliding end 2131 reaches the end 3142 of the limiting groove 314. The positioning protrusion 213 is tightly fitted with the surface forming the corresponding limiting groove 314, thereby tightly positioning the mounting portion 211 of the rigid inner spoon 21 on the outer surface 3125 of the light guide tube 312. The end 3142 of the limiting groove 314 can have a smaller width, thereby further limiting the maximum sliding displacement of the positioning protrusion 213 and preventing the positioning protrusion 213 from separating from the corresponding limiting groove 314.

[0107] like Figure 2B and Figure 4As shown in , the cross section of the limiting ridge 313 is triangular, the corresponding cross section of the limiting groove 314 is also triangular, and the cross section of the positioning ridge 213 is also triangular, so that the surface of the positioning ridge 213 fits tightly with the surface of the limiting protrusion 313.

[0108] It can be understood that by providing the corresponding positioning ridges 213 and the limiting ridges 313, it can be more stable compared to the threaded connection method, and the assembly position of the mounting portion 211 of the rigid inner spoon 21 and the outer surface 3125 of the light guide tube 312 can be determined, thereby avoiding the mounting portion 211 of the rigid inner spoon 21 and the outer surface 3125 of the light guide tube 312 in a similar threaded connection method from sliding easily along the axial direction.

[0109] It is worth mentioning that the light guide tube 312 is used to detachably install the ear spoon assembly 20, and the camera 40 does not extend into the light guide tube 312, thereby avoiding the camera 40 from being squeezed and damaged during the installation of the mounting portion 211 of the rigid inner spoon 21 of the ear spoon assembly 20 in the light guide tube 312.

[0110] In addition, the rod body 311 of the fixed rod 31 has an annular top surface 3111 at a position adjacent to the light guide tube 312, and the mounting portion 211 of the rigid inner spoon 21 has an annular bottom surface 2112 at the bottom end. When the mounting portion 211 of the rigid inner spoon 21 is assembled to the outside of the light guide tube 312, the annular bottom surface 2112 of the mounting portion 211 abuts against the annular top surface 3111 of the rod body 311, and the outer diameter of the annular mounting portion 211 is the same as the outer diameter of the rod body 311, so that the outer surface 2113 of the mounting portion 211 of the rigid inner spoon 21 is connected to the outer surface 3112 of the rod body 311 to form a continuous cylindrical outer surface.

[0111] It is worth mentioning that Figures 2A to 4 As shown in , when the mounting portion 211 of the rigid inner spoon 21 is assembled to the outside of the light guide tube 312, the top edge 2133 of the positioning ridge 213 of the mounting portion 211 is located below the top edge 3126 of the light guide tube 312. In this way, the positioning ridge 213 does not extend into the light path of the light source assembly 50, thereby preventing the light emitted by the light source assembly 50 from being projected onto the structure of the positioning ridge 213 and generating stray light.

[0112] The lengths of the mounting portion 211 and the light guide tube 312 can be similar, thereby reducing reflections of light emitted by the light source assembly 50. The length of the mounting portion 211 can be slightly greater than that of the light guide tube 312, and its inner surface 2111 has a smooth top edge surface 21111, thereby ensuring that the light guide tube 312 is covered by the mounting portion 211. The top edge surface 21111 is a smooth surface and does not have the positioning ridges 213, thereby not affecting the light path of the light source assembly 50.

[0113] Accordingly, the light guide wall 3121 of the light guide tube 312 has excellent mirror reflection performance. For example, the material of the light guide tube 312 is a material with high light reflectivity, such as aluminum, nickel, silver, etc., or the light guide tube 312 is coated with a film such as an aluminum film, a nickel film, or a silver film to form a mirror reflection surface on the light guide wall 3121. Therefore, when the light emitted by the light source assembly 50 is incident on the light guide wall 3121, it can be effectively reflected toward the opening 3123. In addition, the light guide wall 3121 has good polishing performance. When the light reflected from the ear back to the light guide tube 312 is reflected by the light guide wall 3121 toward the camera 40, no stray light that affects the image effect is formed. Figure 6 and Figure 7 As shown in .

[0114] like Figure 2A and Figure 2B As shown in the figure, the light source assembly 50 includes a light source circuit board 51 and a plurality of light-emitting elements 52. The light source circuit board 51 surrounds the camera 40 for mounting the light-emitting elements 52. The top of the light-emitting element 52 forms a light-emitting surface 53. The camera 40 includes a camera body 41 and a connecting circuit board 42, and the top of the camera body 41 forms a lens end surface 43. The light-emitting surface 53 of the light source assembly 50 is flush with the lens end surface 43 of the camera 40 or is located behind the lens end surface 43 of the camera 40, so that the light of the light source assembly 50 is effectively emitted toward the opening 3123 of the light guide tube 312 to illuminate the inner auditory canal of the ear and the ear spoon assembly 20, thereby avoiding the formation of invalid light directly emitted to the camera 40, and also avoiding the side reflection light of the light source assembly 50 to generate stray light emitted to the camera 40.

[0115] The light source circuit board 51 and the connecting circuit board 42 can preferably be implemented as flexible circuit boards, so that they can be conveniently extended in a bendable manner in the fixing rod 31, and the light source circuit board 51 and the connecting circuit board 42 are electrically connected and further electrically connected to the display device 10, so that the camera 40 and the light source assembly 50 can be controlled by the display device 10.

[0116] like Figure 2B As shown in , the fixing assembly 30 further includes a bracket 33 for mounting the camera 40 and the light source assembly 50. The light guide tube 312 of the fixing rod 31 forms an annular step surface 3124 at a position adjacent to the handle 32. The bracket 33 includes an annular end surface 331, which is adhered to the step surface 3124, such as by gluing, so that the bracket 33 is assembled in the handle 32. The bracket 33 accordingly forms an accommodating cavity 332 for accommodating the camera 40. The connecting circuit board 42 can accordingly pass through the bracket 33 to be electrically connected to the display device 10.

[0117] Preferably, the inner surface 333 of the bracket 33 is the same as the inner diameter of the light-guiding wall 3121 of the light-guiding tube 312, so that when the annular end surface 331 of the bracket 33 is attached to the step surface 3124, the inner surface 333 of the bracket 33 and the light-guiding wall 3121 of the light-guiding tube 312 form a continuous cylindrical inner wall, which is used to guide and reflect the light emitted by the light source assembly 50.

[0118] like Figure 3 As shown in the figure, the flexible outer spoon 22 is detachably mounted on the outside of the rigid inner spoon 21, and the end edge 2201 of the flexible outer spoon is used to contact the ear and clean earwax, and its center position 2202 is coaxial with the center 431 of the lens end surface 43 of the camera 40, that is, coaxial with the central axis X of the camera 40, so that the user can accurately judge the position of the end edge 2201 of the flexible outer spoon 22 in the screen image and facilitate the user to operate the ear cleaning device 100 to accurately clean the earwax, and avoid the ear spoon assembly 20 scratching the ear canal and causing infection.

[0119] The light-emitting elements 52 of the light source assembly 50 are evenly distributed around the camera 40, and these light-emitting elements 52 include two median light-emitting elements 521 and 522 located at both ends of the diameter of the lens end surface 43 of the camera 40, that is, two light-emitting elements located on the left and right sides, wherein the center positions of the light-emitting points of the two median light-emitting elements 521 and 522 are on the same straight line with the center 431 of the lens end surface 43 of the camera 40, and the end of the ear pick assembly 20, that is, the end edge 2201 of the flexible outer spoon 22 is in the same plane, thereby ensuring that the center of the end of the ear pick assembly 20 and the earwax in the ear can be located at the center of the field of view of the camera 40, thereby facilitating the user to operate the ear pick assembly 20 to aim at the earwax for cleaning.

[0120] That is to say, the two middle light-emitting elements 521 and 522 respectively emit light, so that the earwax appearing in the field of view of the camera 400 is located exactly at the center position of the end of the ear spoon assembly 20 rather than at the side. Therefore, in the circular image field of view of the display device 10, when the earwax image is displayed at the center of the image field of view, the user can use the center position 2202 of the end edge 2201 of the flexible outer spoon 22 to aim at the earwax and clean the earwax.

[0121] like Figures 2A to 4 As shown in FIG, the flexible outer spoon 22 includes a flexible spoon body 221 and an extension 222, wherein the flexible spoon body 221 integrally extends from the extension 222. The flexible spoon body 221 includes a spoon base 2211 and a flange 2212 integrally extending from the spoon base 2211. The flange 2212 and the spoon base 2211 form a groove 2213 for accommodating earwax. The end of the flange 2212 forms the end edge 2201 of the flexible outer spoon 22. The end edge 2201 of the flexible outer spoon 22 is parallel to and coplanar with the two intermediate light-emitting elements 521 and 522. The center 2202 of the end edge 2201 is coaxial with the center 431 of the lens end surface 43 of the camera 40.

[0122] The flexible outer spoon 22 has a mounting channel 223 extending inside the extension portion 222 and the flexible spoon body portion 221 for mounting the inner spoon body 212 of the rigid inner spoon 21. The inner spoon body 212 of the rigid inner spoon 21 includes a rigid spoon body 2121 and a connecting portion 2122. The connecting portion 2122 integrally extends from the mounting portion 211, and the rigid spoon body 2121 integrally extends from the connecting portion 2122.

[0123] The rigid spoon body 2121 of the inner spoon main body 212 of the rigid inner spoon 21 has an end 21211. When the end 21211 of the rigid spoon body 2121 abuts against the end 2231 of the mounting channel 223 of the flexible outer spoon 22, the end edge 2201 of the front end of the flange portion 2212 of the flexible spoon body 221 is exactly located so that the center position 2202 of its end edge 2201 is coaxial with the center 431 of the lens end surface 43 of the camera 40, and is in the same plane as the center position of the light-emitting points of the two mid-position light-emitting elements 521 and 522 and the center 431 of the lens end surface 43 of the camera 40.

[0124] like Figure 8As shown in FIG, a user can hold the handle 32 to guide the distal end 2201 of the ear pick assembly 20 into their ear, and the light emitted by the light source assembly 50 is irradiated into the ear. The camera 40 captures the flexible outer spoon 22 of the ear pick assembly 20 and an image of the interior of the ear, and displays the image on the display 11 of the display device 10. The distal end 2201 of the flexible outer spoon 22 of the ear pick assembly 20 is located at the center of the circular image field, and facilitates scraping earwax from the ear into the groove 2213 of the flexible spoon body 221, and then removes the earwax as the ear pick assembly 20 is removed from the ear.

[0125] like Figures 9 to 25 FIG shows an ear cleaning device 100 according to a second preferred embodiment of the present invention, comprising an ear spoon assembly 20, a fixing assembly 30, a camera 40, a light source assembly 50, and a controller 60. In this embodiment of the present invention, the ear cleaning device 100 can be wirelessly connected to an electronic device 1 such as a mobile phone or tablet computer, so that the user can view the image of the inside of the ear captured by the camera 40 in real time on the electronic device 1.

[0126] In this embodiment, the ear spoon assembly 20 is connected to the fixing assembly 30 for cleaning earwax in the ear. The camera 40, the light source assembly 50 and the controller 60 are assembled in the fixing assembly 30. The light source assembly 50 provides a fill light effect for the camera 40 to illuminate the positions in the ear that need to be illuminated, such as the concha cavity, the ear canal, etc., during the ear cleaning operation.

[0127] Accordingly, the controller 60 is communicatively connected to the electronic device 1, that is, the controller 60 can be implemented as including a control circuit board 61 and integrated with a wireless communication module, such as a cellular network module, a WiFi module, a Bluetooth module or a ZigBee module, so that the electronic device 1 can obtain the image information obtained by the camera 40 of the ear cleaning device 100 through wireless communication.

[0128] The controller 60 is also configured with a power module 62, which is electrically connected to the control circuit board 61 and further electrically connected to the camera 40 and the light source assembly 50, thereby providing power to the camera 40 and the light source assembly 50. The power module 62 may include a rechargeable battery, including but not limited to a nickel-cadmium battery, a nickel-metal hydride battery, a lead-acid battery, a lithium-ion battery, a lithium polymer battery, etc.

[0129] The fixing assembly 30 includes a fixing rod 31 and a handle 32. The fixing rod 31 is used to assemble the camera 40 and the light source assembly 50, and the ear pick assembly 20 is connected to the fixing rod 31. The handle 32 is connected to the fixing rod 31 to accommodate the control circuit board 61 and the power module 62 of the controller 60 and to be held by the user's hand, so that the user can hold the handle 32 to place the front end of the ear pick assembly 20 in their ear to perform an ear cleaning operation.

[0130] The controller 60 also includes a control switch 63, which can be implemented as a button or a knob. Figures 9 to 11 The controller 60 further includes a charging port 64 electrically connected to the power module 62 so as to charge the rechargeable battery in the power module 62 when connected to an external power source.

[0131] like Figures 11 to 12 As shown in FIG, in this embodiment, the handle 32 includes a handle body 321 and a cover 322. The handle body 321 defines a housing chamber 323. The cover 322 is assembled to the handle body 321 to provide a flat surface for printing product logos. The housing chamber 323 is used to accommodate the control circuit board 61 and the power module 62.

[0132] In this embodiment of the present invention, the fixing rod 31 is implemented as a hollow fixed cylinder, and the camera 40 and the light source assembly 50 are built into the fixing cylinder. The diameter of the fixing rod 31 is smaller than that of the handle 32, and the handle 32 has a relatively large diameter, thereby facilitating the user's grip and operation. In this embodiment, the fixing rod 31 and the handle 32 are assembled and fixed, such as by bonding or using screws.

[0133] In this embodiment, the ear pick assembly 20 is detachably connected to the fixing rod 31 of the fixing assembly 30, so that the user can easily replace the ear pick assembly 20 of different sizes and select the ear pick assembly 20 that suits him / her. Figures 9 to 17 、 Figures 18 to 20 or Figure 22-23 Select from the ear pick assembly 20 shown in FIG.

[0134] like Figures 13A to 15As shown in FIG, the ear spoon assembly 20 includes a rigid inner spoon 21 and a flexible outer spoon 22. The flexible outer spoon 22 is detachably mounted on the rigid inner spoon 21. It is understood that the rigid inner spoon 21 is made of a rigid material. The flexible outer spoon 22 is made of a flexible material, which flexibly contacts the user's ear and does not scratch the user's ear.

[0135] The rigid inner spoon 21 includes a mounting portion 211 and an inner spoon body 212. The inner spoon body 212 integrally extends from the mounting portion 211, and the flexible outer spoon 22 is sleeved on the inner spoon body 212. In this embodiment, the mounting portion 211 is annular, and the inner spoon body 212 integrally extends from a partial edge of the annular mounting portion 211. The mounting portion 211 is configured to be detachably assembled with the fixing rod 31.

[0136] More specifically, if Figures 11 to 14 As shown in , the fixing rod 31 includes a rod body 311 and a light guide tube 312. The light guide tube 312 is integrally connected to the rod body 311 and is located in front of the camera 40 and the light source assembly 50, thereby guiding the light emitted by the light source assembly 50. The rod body 311 includes a joint end 3114, which is suitable for being inserted into and bonded to the front end of the handle 32, thereby assembling the fixing rod 31 and the handle 32.

[0137] In this embodiment, the rod body 311 can also form a cylinder, the diameter of the light guide tube 312 is smaller than the diameter of the rod body 311, the camera 40 is built into the rod body 311 without extending into the light guide tube 312, and the light guide tube 312 is also located in front of the light source assembly 50, and the light guide tube correspondingly forms a light guide wall 3121 by its inner wall, and the light guide wall 3121 forms a light guide channel 3122 and forms an opening 3123 at the front end that is connected to the light guide channel 3122, so that Part of the light from the light source assembly 50 can be directly emitted into the ear through the opening 3123, and another part of the light is reflected by the light guide wall 3121 and then guided into the ear and the end of the ear spoon assembly 20 through the light guide channel 3122 and the opening 3123. In this way, the light from the light source assembly 50 is evenly guided to the position that needs to be illuminated, and the light guide tube 312 prevents external stray light from entering the field of view of the camera 40, thereby reducing glare or dark spots and providing the user with a clearer image on the display 11.

[0138] In addition, in this embodiment, the light guide tube 312 is further used to be detachably connected to the mounting portion 211 of the rigid inner spoon 21. Figure 15As shown in , one or more fixing groove structures are formed on the outer surface 3125 of the light guide tube 312, which include a longitudinal guide groove 315 and a locking groove 316 extending transversely to the bottom end of the guide groove 315. One or more positioning protrusions 213 are protruded from the inner surface 2111 of the mounting portion 211 of the rigid inner spoon 21. The positioning protrusions 213 correspond to the shape and size of the locking groove 316 and the size of the notch 3151 at the top of the guide groove 315. Thus, the positioning protrusions 213 are adapted to enter the guide groove 315 through the notch 3151 at the top of the guide groove 315, and then transversely enter the locking groove 316, thereby being retained in the locking groove 316, so that the mounting portion 211 of the rigid inner spoon 21 is assembled to the outside of the light guide tube 312.

[0139] More specifically, during the assembly of the mounting portion 211 of the rigid inner spoon 21 onto the outer surface 3125 of the light guide tube 312, the ear spoon assembly 20 is first inserted onto the outer surface of the light guide tube 312 along the longitudinal direction, i.e., the length of the fixing rod 31. The positioning protrusion 213 is aligned with the notch 3151 at the top of the guide groove 315, allowing the positioning protrusion 213 to slide within the guide groove 315. When the positioning protrusion 213 reaches the bottom of the guide groove 315, the mounting portion 211 is rotated, causing the positioning protrusion 213 to enter the locking groove 316. Preferably, the positioning protrusion 213 and the locking groove 316 further form an interference fit, preventing the positioning protrusion 213 from easily disengaging from the fixing groove structure, thereby firmly securing the ear spoon assembly 20 to the outer surface 3125 of the light guide tube 312.

[0140] It can be understood that by providing the corresponding positioning protrusion 213 and the guide groove 315 and the locking groove 316 structure, it can be more stable compared to the threaded connection method, and the assembly position of the mounting portion 211 of the rigid inner spoon 21 and the outer surface 3125 of the light guide tube 312 can be determined, thereby avoiding the mounting portion 211 of the rigid inner spoon 21 and the outer surface 3125 of the light guide tube 312 in a similar threaded connection method from sliding easily along the axial direction.

[0141] The light guide tube 312 is used to detachably mount the ear pick assembly 20 , and the camera 40 does not extend into the light guide tube 312 , thereby preventing the camera 40 from being squeezed and damaged during the installation of the mounting portion 211 of the rigid inner spoon 21 of the ear pick assembly 20 in the light guide tube 312 .

[0142] In addition, the rod body 311 of the fixed rod 31 has an annular top surface 3111 at a position adjacent to the light guide tube 312, and the mounting portion 211 of the rigid inner spoon 21 has an annular bottom surface 2112 at the bottom end. When the mounting portion 211 of the rigid inner spoon 21 is assembled to the outside of the light guide tube 312, the annular bottom surface 2112 of the mounting portion 211 abuts against the annular top surface 3111 of the rod body 311, and the outer diameter of the annular mounting portion 211 is the same as the outer diameter of the rod body 311, so that the outer surface 2113 of the mounting portion 211 of the rigid inner spoon 21 is connected to the outer surface 3112 of the rod body 311 to form a continuous cylindrical outer surface.

[0143] It is worth mentioning that Figure 15 As shown in the figure, the guide groove 315 and the locking groove 316 are recessed in the outer surface 3125 of the light guide tube 312 without penetrating the light guide tube 312. When the mounting portion 211 is assembled to the light guide tube 312, the positioning ridge 213 is arranged on the bottom inner surface of the inner surface 2111 of the mounting portion 211 and is adjacent to the bottom opening of the annular mounting portion 211, so that the top edge 213 is located below the top edge 3126 of the light guide tube 312. In this way, the positioning ridge 213 does not extend into the light path of the light source assembly 50 to avoid the light emitted by the light source assembly 50 from being projected onto the structure of the positioning ridge 213 to generate stray light.

[0144] The lengths of the mounting portion 211 and the light guide tube 312 can be similar, thereby reducing reflections of light emitted by the light source assembly 50. The length of the mounting portion 211 can be slightly greater than that of the light guide tube 312, and its inner surface 2111 has a smooth top edge surface 21111 located above the positioning ridge 213, thereby ensuring that the light guide tube 312 is covered by the mounting portion 211. The top edge surface 21111 is a smooth surface without the positioning ridge 213, thereby not affecting the light path of the light source assembly 50.

[0145] Correspondingly, the light guide wall 3121 of the light guide tube 312 has excellent mirror reflection performance. For example, the material of the light guide tube 312 is a material with high light reflectivity such as aluminum, nickel, silver, etc., or the light guide tube 312 is coated with a film such as an aluminum film, a nickel film or a silver film to form a mirror reflection surface of the light guide wall 3121, so that when the light emitted by the light source assembly 50 is incident on the light guide wall 3121, it can be effectively reflected toward the opening 3123, and the light guide wall 3121 has good polishing performance, and the light reflected from the ear back to the light guide tube 312 will not form stray light that affects the image effect when it is reflected by the light guide wall 3121 toward the camera 40.

[0146] like 13A to 13B As shown in the figure, the light source assembly 50 includes a light source circuit board 51 and a plurality of light-emitting elements 52. The light source circuit board 51 surrounds the camera 40 for mounting the light-emitting elements 52. The top of the light-emitting element 52 forms a light-emitting surface 53. The camera 40 includes a camera body 41 and a connecting circuit board 42, and the top of the camera body 41 forms a lens end surface 43. The light-emitting surface 53 of the light source assembly 50 is flush with the lens end surface 43 of the camera 40 or is located behind the lens end surface 43 of the camera 40, so that the light of the light source assembly 50 is effectively emitted toward the opening 3123 of the light guide tube 312 to illuminate the inner auditory canal of the ear and the ear spoon assembly 20, thereby avoiding the formation of invalid light directly emitted to the camera 40, and also avoiding the side reflection light of the light source assembly 50 to generate stray light emitted to the camera 40.

[0147] The light source circuit board 51 and the connecting circuit board 42 can preferably be implemented as flexible circuit boards, so that they can be conveniently extended in a bendable manner in the fixing rod 31, and the light source circuit board 51 and the connecting circuit board 42 are electrically connected and further electrically connected to the control circuit board 61 of the controller 60, so that the camera 40 and the light source assembly 50 can be controlled by the switching element 63.

[0148] like Figures 13A to 14 As shown in , the fixing assembly 30 also includes a bracket 33 for mounting the camera 40 and the light source assembly 50. The light guide tube 312 of the fixing rod 31 forms an annular step surface 3124 at a position adjacent to the handle 32. The bracket 33 includes an annular end surface 331, which is adhered to the step surface 3124, such as by gluing, so that the bracket 33 is assembled in the handle 32. The bracket 33 correspondingly forms an accommodating cavity 332 for accommodating the camera 40. The connecting circuit board 42 can accordingly pass through the bracket 33 to be electrically connected to the control circuit board 61.

[0149] Preferably, the inner surface 333 of the bracket 33 is the same as the inner diameter of the light-guiding wall 3121 of the light-guiding tube 312, so that when the annular end surface 331 of the bracket 33 is attached to the step surface 3124, the inner surface 333 of the bracket 33 and the light-guiding wall 3121 of the light-guiding tube 312 form a continuous cylindrical inner wall, which is used to guide and reflect the light emitted by the light source assembly 50.

[0150] The bracket 33 and the fixing rod 31 can be made of a material with good thermal conductivity so that heat can be dissipated into the environment through the outer surface of the fixing rod 31, thereby preventing heat from being transferred to the ear pick assembly 20 and maintaining a relatively low temperature of the ear pick assembly 20. Alternatively, the fixing rod 31 can be made of a thermally insulating material so that heat generated by the camera 40 and the light source assembly 50 during operation is transferred from the connecting circuit board 42 to the handle 32, thereby dissipating heat at the handle 32 and preventing heat from being transferred to the ear pick assembly 20.

[0151] The rigid inner spoon 21 and the fixing rod 31 of the ear spoon assembly 20 can be made of the same material, or they can be made of different materials. For example, the rigid inner spoon 21 can be made of a plastic with poorer thermal conductivity than the fixing rod. In this way, the rigid inner spoon 21 prevents heat generated by the camera 40 and the light source assembly 50 from being transferred to the distal end of the ear spoon assembly 20 via the fixing rod 31 during operation.

[0152] In addition, the connecting circuit board 42 is a flexible circuit board, which is located in the fixing rod 31 and can be bent and extended so as to be conveniently extended in the fixing rod 31 .

[0153] The fixing assembly 30 also includes a transparent sealing element 34, which is bonded to the bracket 33 via a waterproof adhesive layer 35 to serve as a transparent cover to seal the camera 40 and the light source assembly 50. The sealing element 34 can be attached to the light guide tube 312 of the fixing rod 31, forming an annular stepped surface 3124 adjacent to the handle 32. The waterproof adhesive layer 35 includes, but is not limited to, silicone sealant, epoxy resin sealant, polyurethane sealant, acrylic sealant, butyl rubber adhesive, etc. Preferably, to facilitate manufacturing, the waterproof adhesive layer 35 can be a UV-curable adhesive. This prevents water from entering the light guide tube 312 during cleaning of the fixing rod 31 or during cleaning of the ear spoon assembly 20, thereby preventing damage to the camera 40, the light source assembly 50, and the control circuit board 61.

[0154] It is worth mentioning that the transparent sealing element 34 preferably further has hydrophobic properties, and its contact angle with water is greater than 90 degrees. In this way, after the ear cleaning device 100 is cleaned with water, if water enters the light guide tube 312, water droplets will not be retained on the transparent sealing element 34. In this way, the user does not need to wait for the water to evaporate and can immediately use the ear cleaning device 100, thereby avoiding wasting the user's time.

[0155] It is understood that the hydrophobic material of the transparent sealing element 34 may include but is not limited to polyurethane compounds, polyimide compounds, organic silane compounds, fluorocarbon compounds, fluoroalkenyl ether polymers, fluorine-containing silane compounds, fluorine-containing acrylate compounds, methyltrimethoxysilane, propyltrimethoxysilane, vinyltriethoxysilane, isopropyl tris(dioctylpyrophosphate) titanate, benzyl aluminate, titanium dioxide hydrogenated silicon carbon nitride film, etc.

[0156] like Figure 18 As shown in , according to another variant embodiment, the transparent sealing element 34 may also be a coating layer, which is a hydrophobic layer and is coated on the outer surfaces of the camera 40 and the light source assembly 50 .

[0157] like Figure 14 As shown in the figure, the flexible outer spoon 22 is detachably mounted on the outside of the rigid inner spoon 21, and the end edge 2201 of the flexible outer spoon is used to contact the ear and clean earwax, and its center position 2202 is coaxial with the center 431 of the lens end surface 43 of the camera 40, that is, coaxial with the central axis X of the camera 40, so that the user can accurately judge the position of the end edge 2201 of the flexible outer spoon 22 in the screen image and facilitate the user to operate the ear cleaning device 100 to accurately clean the earwax, and avoid the ear spoon assembly 20 scratching the ear canal and causing infection.

[0158] The light-emitting elements 52 of the light source assembly 50 are evenly distributed around the camera 40, and these light-emitting elements 52 include two median light-emitting elements 521 and 522 located at both ends of the diameter of the lens end surface 43 of the camera 40, that is, two light-emitting elements located on the left and right sides, wherein the center positions of the light-emitting points of the two median light-emitting elements 521 and 522 are on the same straight line with the center 431 of the lens end surface 43 of the camera 40, and the end of the ear pick assembly 20, that is, the end edge 2201 of the flexible outer spoon 22 is in the same plane, thereby ensuring that the center of the end of the ear pick assembly 20 and the earwax in the ear can be located at the center of the field of view of the camera 40, thereby facilitating the user to operate the ear pick assembly 20 to aim at the earwax for cleaning.

[0159] That is to say, the two middle light-emitting elements 521 and 522 respectively emit light, so that the earwax appearing in the field of view of the camera 400 is located exactly at the center position of the end of the ear spoon assembly 20 rather than at the side. Therefore, in the circular image field of view of the electronic device 1, when the earwax image is displayed at the center of the image field of view, the user can use the center position 2202 of the end edge 2201 of the flexible outer spoon 22 to aim at the earwax and clean the earwax.

[0160] like Figures 12 to 15As shown in FIG, the flexible outer spoon 22 includes a flexible spoon body 221 and an extension 222, wherein the flexible spoon body 221 integrally extends from the extension 222. The flexible spoon body 221 includes a spoon base 2211 and a flange 2212 integrally extending from the spoon base 2211. The flange 2212 and the spoon base 2211 form a groove 2213 for accommodating earwax. The end of the flange 2212 forms the end edge 2201 of the flexible outer spoon 22. The end edge 2201 of the flexible outer spoon 22 is parallel to and coplanar with the two intermediate light-emitting elements 521 and 522. The center 2202 of the end edge 2201 is coaxial with the center 431 of the lens end surface 43 of the camera 40.

[0161] The flexible outer spoon 22 has a mounting channel 223 extending inside the extension portion 222 and the flexible spoon body portion 221 for mounting the inner spoon body 212 of the rigid inner spoon 21. The inner spoon body 212 of the rigid inner spoon 21 includes a rigid spoon body 2121 and a connecting portion 2122. The connecting portion 2122 integrally extends from the mounting portion 211, and the rigid spoon body 2121 integrally extends from the connecting portion 2122.

[0162] The rigid spoon body 2121 of the inner spoon main body 212 of the rigid inner spoon 21 has an end 21211. When the end 21211 of the rigid spoon body 2121 abuts against the end 2231 of the mounting channel 223 of the flexible outer spoon 22, the end edge 2201 of the front end of the flange portion 2212 of the flexible spoon body 221 is exactly located so that the center position 2202 of its end edge 2201 is coaxial with the center 431 of the lens end surface 43 of the camera 40, and is in the same plane as the center position of the light-emitting points of the two mid-position light-emitting elements 521 and 522 and the center 431 of the lens end surface 43 of the camera 40.

[0163] like Figure 16 As shown in the figure, the end 21211 of the rigid spoon body 2121 is not coaxial with the center 431 of the lens end face 43 of the camera 40. When the flexible outer spoon 22 is mounted on the rigid inner spoon 21, as shown in the figure, the end edge 2201 of the flange portion 2212 of the flexible spoon body 221 is exactly in a position where the center position 2202 of the end edge 2201 is coaxial with the center 431 of the lens end face 43 of the camera 40.

[0164] like Figure 17As shown in FIG, the flexible spoon body 221 of the flexible outer spoon 22 is offset toward the central axis X of the camera 40, such that the center position 2202 of the end edge 2201 is coaxial with the center 431 of the lens end surface 43 of the camera 40. The rigid spoon body 2121 is offset toward the central axis X of the camera 40, thereby supporting the flexible spoon body 221 of the flexible outer spoon 22.

[0165] like Figures 19 to 21 As shown in , according to a variant embodiment, the flexible outer spoon 22 can be configured in another shape. Specifically, the flexible spoon body 221 of the flexible outer spoon 22 forms a tip 2203. The flexible spoon body 221 gradually increases in size from the tip 2203 toward a portion of the extension 222, forming a curved transition surface 2204. In other words, the flexible spoon body 221 lacks the aforementioned edge 2201, and the tip 2203 forms the center position 2202 of the end of the flexible spoon body 221. Furthermore, the tip 2203 is coaxial with the center 431 of the lens end surface 43 of the camera 40, that is, coaxial with the central axis X of the camera 40. This allows the user to accurately determine the position of the tip 2203 of the flexible outer spoon 22 in the image, facilitates the user's operation of the ear cleaning device 100, and precisely removes earwax. This also prevents the ear spoon assembly 20 from scratching the ear canal and causing infection.

[0166] In addition, the center positions of the light-emitting points of the two middle light-emitting elements 521 and 522 of the light source assembly 50 are on the same straight line as the center 431 of the lens end surface 43 of the camera 40, and are in the same plane as the tip 2203 of the flexible outer spoon 22, thereby ensuring that the center of the end of the ear spoon assembly 20 and the earwax in the ear can be located at the center of the field of view of the camera 40.

[0167] like Figures 22 to 23 As shown in FIG , according to another variant embodiment, the ear pick assembly 20 includes an ear pick element 23, which includes a mounting portion 231 and a spoon body portion 232. In this embodiment, unlike the ear pick assembly 20 comprising an inner spoon and an outer spoon in the above-mentioned embodiment, the ear pick element 23 consists of a single component. The mounting portion 231 can be constructed similarly to the structure in the above-mentioned embodiment, and is equipped with a detachable connection structure such as a thread, a snap, or the aforementioned positioning protrusion and positioning groove structure, so that it can be detachably assembled to the light guide tube 312.

[0168] In this embodiment, the ear pick element 23 is made of a transparent plastic material. This ensures that the light emitted by the light source assembly 50 is not blocked by the ear pick element 23, thereby enabling the capture of more image information within the human ear. In other words, in the aforementioned embodiment, when the rigid inner spoon 21 is made of, for example, a metal material, the portion of the ear corresponding to its location cannot be captured by the camera 40. However, in the present invention, image information within the ear located in front of the ear pick element 23 can also be captured by the camera 40.

[0169] Additionally, the ear pick element 23 and the fixing rod 31 may be made of different materials. For example, the ear pick element 23 may be made of a material with lower thermal conductivity than the fixing rod 31. This prevents heat generated by the camera 40 and the light source assembly 50 from being transferred through the fixing rod 31 to the distal end of the ear pick element 23 and causing a burning sensation in the human ear.

[0170] like Figure 23 As shown in the figure, the center position 233 of the end of the ear pick element 23 is coaxial with the center 431 of the lens end surface 43 of the camera 40, that is, coaxial with the central axis X of the camera 40, so that the user can accurately determine the position of the center position 233 of the end of the ear pick element 23 in the screen image and conveniently operate the ear cleaning device 100 to accurately clean earwax, and avoid the ear pick assembly 20 scratching the ear canal and causing infection.

[0171] In addition, the center positions of the light-emitting points of the two middle light-emitting elements 521 and 522 of the light source assembly 50 are on the same straight line as the center 431 of the lens end surface 43 of the camera 40, and are in the same plane as the center position 233 of the end of the ear pick element 23, thereby ensuring that the center of the end of the ear pick assembly 20 and the earwax in the ear can be located at the center of the field of view of the camera 40.

[0172] like Figure 24 As shown in , according to another variant embodiment, the rigid inner spoon 21 of the ear spoon assembly 20 can be integrally connected to the light guide tube 312, so that the rigid inner spoon 21 is integrally fixed to the fixing rod 31 and cannot be detached.

[0173] like Figures 25 to 28As shown in FIG, according to another variant embodiment, an ear cleaning device 100 includes an ear spoon assembly 20, a fixing assembly 30, a camera 40, a light source assembly 50, and a controller 60. In this embodiment of the present invention, the ear cleaning device 100 can be wirelessly connected to an electronic device 1 such as a mobile phone or tablet computer, so that the user can view the image inside the ear captured by the camera 40 in real time on the electronic device 1.

[0174] In this embodiment, the ear spoon assembly 20 includes a rigid base 24 and a flexible body 25. The flexible body 25 is mounted above the rigid base 24 to contact the user's ear. That is, unlike the previous embodiment, where the flexible outer spoon 22 is sheathed over the rigid inner spoon 21, the flexible body 25 in this embodiment is superimposed on the rigid base 24.

[0175] Accordingly, as shown in the figure, the rigid spoon base 24 includes a mounting portion 241 and a spoon base body 242. The spoon base body 242 integrally extends from the mounting portion 241, and the mounting portion 241 is connected to the fixing assembly 30. The flexible spoon body 25 includes a flexible spoon body 251 and an extension portion 252. The flexible spoon body 251 integrally extends from the extension portion 252. The spoon base body 242 includes an inclined rigid spoon body 2421. The flexible spoon body 251 of the flexible spoon body 25 is mounted on the inclined rigid spoon body 2421, so that the flexible spoon body 251 extends inward to facilitate ear cleaning operations.

[0176] In this embodiment, the fixing assembly 30 includes a fixing rod 31 and a handle 32. The rod 31 includes a rod body 311 and a sleeve 313. The rod body 311 is used to mount the camera 40 and the light source assembly 50. In this embodiment, the mounting portion 241 of the rigid spoon base 24 extends into the rod body 311 to form a light guide tube 2411. The light guide tube 2411 is located in front of the camera 40 and the light source assembly 50. The mounting portion 241 of the rigid spoon base 24 is mounted on the light guide tube 313, and the sleeve 313 is sleeved on the outside of the light guide tube 312 and the mounting portion 241.

[0177] As shown in the figure, the light source assembly 50 includes a light source circuit board 51 and a plurality of light-emitting elements 52. The light source circuit board 51 surrounds the camera 40 for mounting the light-emitting elements 52. A light-emitting surface 53 is formed at the top of the light-emitting element 52. The camera 40 includes a camera body 41 and a connecting circuit board 42, and a lens end surface 43 is formed at the top of the camera body 41. The light-emitting surface 53 of the light source assembly 50 is located behind the lens end surface 43 of the camera 40, so that the light of the light source assembly 50 is effectively emitted toward the opening 3123 of the light guide tube 312 to illuminate the inner auditory canal of the ear and the ear spoon assembly 20, thereby avoiding the formation of invalid light directly directed toward the camera 40, and also avoiding the side reflection light of the light source assembly 50 to generate stray light directed toward the camera 40.

[0178] In addition, a waterproof adhesive layer 35 is provided on the light-emitting surface 53 of the light source assembly 50. During the manufacturing process, the waterproof adhesive layer 35 is applied to the entire light-emitting surface 53 of the light source assembly 50 and is used to securely install the light source assembly 50. The waterproof adhesive layer 35 is a transparent adhesive layer and can be implemented as a UV-curable adhesive, which facilitates dispensing and curing, and does not affect the light output effect of the light source assembly 50 after curing.

[0179] It is worth mentioning that because the waterproof adhesive layer 35 needs to be set on the light-emitting surface 53 of the light source assembly 50, the light-emitting surface 53 of the light source assembly 50 is located behind the lens end surface 43 of the camera 40. Therefore, when applying glue on the light-emitting surface 53 of the light source assembly 50, the fluid waterproof adhesive layer 35 will not be applied to the lens end surface 43 of the camera 40, thereby not affecting the shooting effect of the camera 40.

[0180] In this embodiment, a transparent sealing element 34 is further provided on the lens end surface 43 of the camera 40, which has a hydrophobic structure. In this way, after the ear cleaning device is cleaned with water, water droplets are not likely to remain in front of the camera 40, so that the ear cleaning device can be used by the user in a timely manner without wasting the user's time.

[0181] It is understood that the waterproof adhesive layer 35 in this embodiment is applied to the light source assembly 50 and used to install the light source assembly 50 to achieve a waterproof effect, and the transparent sealing element 34 with a hydrophobic property is provided on the lens end face 43, which can also be applied to the above Figures 1 to 24 In the embodiment illustrated in FIG.

[0182] In this embodiment, the fixing rod 31 of the fixing assembly 30 further includes a connecting portion 317, which integrally extends from the rod body 311 for assembly with the handle 32. Figures 29 to 30 As shown in FIG, the fixing rod 31 of the fixing assembly 30 further includes a connecting portion 317, which is assembled with the rod body 311 for assembly with the handle 32. The rod body 311 passes through the connecting portion 317 for assembly with the ear spoon assembly 20. Figure 31 As shown in FIG, a user can wirelessly connect to the ear cleaning device 100 via the electronic device 1. For example, the electronic device 1 can download a mobile phone application to control the ear cleaning device 100. The user can hold the handle 32 to guide the tip 2201 of the ear pick assembly 20 into their ear. The light emitted by the light source assembly 50 is directed into the ear. The camera 40 captures the flexible outer spoon 22 of the ear pick assembly 20 and images of the ear, and the image information captured by the camera 40 is displayed on the electronic device 1, such as a mobile phone or tablet. The tip 2201 of the flexible outer spoon 22 of the ear pick assembly 20 is located in the center of the circular image field, facilitating the scraping of earwax into the groove 2213 of the flexible spoon body 221, which is then removed from the ear by the ear pick assembly 20.

[0183] It should be noted that in the apparatus and method of the present application, the components or steps in different embodiments may be decomposed and / or recombined without departing from the principles of the present invention. Such decomposition and / or recombination should be considered as included within the inventive concept of the present application.
