[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] In order to solve the technical problems in the prior art that the separate disinfection structure of the ear-picking stick is unstable and has limited usage scenarios, the present application proposes an ear-picking stick with a disinfection structure.

[0038] See also Figure 1-2 , Figure 1 This is an exploded view of the ear-cleaning stick with a disinfection structure in an embodiment of the present application. Figure 2 Schematic diagram of the disinfection structure 30, the ear-cleaning rod with a disinfection structure of the present application includes a housing 10, an image acquisition component 20, a disinfection structure 30 and a functional component 40. In the embodiment of the present application, the housing 10 includes a gripping section 11, a neck section 12, a first mounting frame 13 and a second mounting frame 14, wherein the gripping section 11 and the neck section 12 are arranged along the axial direction of the ear-cleaning rod, the first mounting frame 13 is disposed in the gripping section 11 and connected to the gripping section 11, and the second mounting frame 14 is disposed in the neck section 12 and connected to the neck section 12. In this embodiment, the user holds and operates the gripping section 11 and controls the neck section 12 to enter the ear to complete ear care, therefore, the diameter of the neck section 12 is smaller than the diameter of the gripping section 11. It should be noted that, considering the structural strength and stability, the grip section 11 and the neck section 12 can be of a non-detachable structure, for example, the grip section 11 and the neck section 12 are an integrally formed structure; considering the convenience of transportation and maintenance, the grip section 11 and the neck section 12 can be of a detachable structure, for example, the grip section 11 and the neck section 12 are detachably connected. Similarly, the first mounting frame 13 and the second mounting frame 14 are detachably connected, or the first mounting frame 13 and the second mounting frame 14 are an integrally formed structure.

[0039] Further, the image acquisition component 20 is disposed in the housing 10 and mounted on an end of the second mounting frame 14 away from the first mounting frame 13. It can be understood that the functional component 40 is mounted on one end of the housing 10 and is located within the field of view of the image acquisition component 20. The user collects images in the ear canal based on the image acquisition component 20 and operates the functional component 40 to care for the ear canal.

[0040] See also Figure 1-Figure 2 Compared with the related art, in the embodiment of the present application, the disinfection structure 30 is arranged in the housing 10, wherein the ultraviolet lamp 31 in the disinfection structure 30 is arranged on the radial inner side of the neck section 12 away from the grip section 11, and is arranged opposite to the functional part 40 along the radial direction of the neck section 12. Specifically, the ultraviolet lamp 31 is installed on the peripheral side of the image acquisition part 20: the ultraviolet lamp 31 and the lighting part 21 form a circle and are arranged around the image acquisition part 20, wherein the lighting part 21 can adopt an LED lighting lamp. It can be understood that the position setting of the ultraviolet lamp 31 in this embodiment makes the distance between the ultraviolet lamp 31 and the functional part 40 the longest. At this time, the ultraviolet lamp 31 can irradiate the functional part 40 to the maximum extent, ensuring a more effective disinfection coverage.

[0041] It should be noted that, in this embodiment, there may be one or more ultraviolet lamps 31. Specifically, when there is one ultraviolet lamp 31 in the disinfection structure 30, the ultraviolet lamp 31 and the functional part 40 are arranged opposite to each other along the radial direction of the neck section 12; when there are multiple ultraviolet lamps 31 in the disinfection structure 30, the multiple ultraviolet lamps 31 are distributed at intervals along the circumference of the inner wall of the neck section 12, and one of the ultraviolet lamps 31 and the functional part 40 are arranged opposite to each other along the radial direction of the neck section 12.

[0042] Furthermore, the disinfection structure 30 also includes a control unit 32, a flexible circuit board 33, a first circuit board 34, a second circuit board 35 and a connector 36. In the embodiment of the present application, the control unit 32 in the disinfection structure 30 is electrically connected to the ultraviolet lamp 31, and is configured to control the opening and closing of the ultraviolet lamp 31 according to a preset mode to achieve intermittent or continuous disinfection of the functional part 40.

[0043] It should be noted that, compared with traditional chemical disinfection methods, ultraviolet disinfection has the characteristics of convenience, low consumption and no residue, so it plays an important role in the field of medical disinfection. Ultraviolet rays, as high-energy light with a certain killing ability, are usually used to disinfect the environment and avoid direct exposure to the human body, but low doses of ultraviolet rays have an immunomodulatory effect on human skin. Based on this, two ultraviolet disinfection modes are designed in the embodiment of the present application: continuous disinfection mode, when the ear-picking stick is used, the control unit 32 will start the ultraviolet lamp 31 and delay closing. In this mode, the ultraviolet lamp 31 will continue to irradiate the functional part 40 for a period of time to ensure that the functional part 40 is thoroughly disinfected; intermittent disinfection mode, during the use of the ear-picking stick, the control unit 32 controls the ultraviolet lamp 31 to turn on and off at preset time intervals. This intermittent irradiation method can play a role in regulating the ear canal environment and avoid continuous irradiation from causing damage to the ear canal.

[0044] Specifically, the control unit 32 includes a mode selection switch 321, a relay circuit 322, a main control circuit 323 and an indicator light 324. Figure 3 , Figure 3The schematic diagram of the circuit block diagram of the control unit 32 in this embodiment, the main control circuit 323 is electrically connected to the mode selection switch 321, the relay circuit 322, and the indicator light 324 respectively, the relay circuit 322 is electrically connected to the ultraviolet lamp 31, and is used to control the opening and closing of the ultraviolet lamp 31, the mode selection switch 321 is used to switch the working mode, and the main control circuit 323 is provided with a microcontroller 3230 and a timer 3231, wherein the microcontroller 3230 responds to the signal of the mode selection switch 321, according to the control instruction of the continuous disinfection mode or the intermittent disinfection mode and controls the on and off of the relay circuit 322 through the timer 3231, so as to realize the continuous disinfection mode or the intermittent disinfection mode. In addition, the indicator light 324 responds to the signal of the main control circuit 323 and indicates the working mode of the ultraviolet lamp 31. For example, the indicator light 324 is configured to flash and light up in the continuous disinfection mode, and is configured to light up continuously in the intermittent disinfection mode. The user can understand the working mode of the ultraviolet lamp 31 through the indicator light 324. Further, the indicator light 324 can adopt an LED indicator light.

[0045] Further, in this embodiment, the control unit 32 is arranged in the grip section 11. Specifically, in the disinfection structure 30, the first circuit board 34 is arranged on one side of the first mounting frame 13, the second circuit board 35 is arranged in parallel and spaced on the side of the first circuit board 34 away from the first mounting frame 13, and the connector 36 is arranged between the first circuit board 34 and the second circuit board 35, and is electrically connected to the first circuit board 34 and the second circuit board 35 respectively. The control unit 32 is arranged on the second circuit board 35 and is electrically connected to the second circuit board 35. Further, the control unit 32 is electrically connected to the ultraviolet lamp 31 through the flexible circuit board 33, wherein the flexible circuit board 33 is spirally received in the second mounting frame 14, one end is electrically connected to the ultraviolet lamp 31, and the other end is electrically connected to the control unit 32. It can be understood that in this embodiment, two layers of circuit boards are provided, which better utilizes the internal space of the grip section 11, can accommodate more components and circuits, and increase the functionality of the ear-picking stick. Among them, the first circuit board 34 and the second circuit board 35 can be disassembled and replaced separately, which improves the maintainability of the product. In addition, the control unit 32 is disposed on the second circuit board 35 and is directly electrically connected to the ultraviolet lamp 31 through the flexible circuit board 33, which can reduce wiring crossover and avoid mutual interference between the control unit 32 and other functional modules.

[0046] See also Figure 4-Figure 5 , Figure 4 is a schematic diagram of a first connection mode of the functional part 40, Figure 5It is a schematic diagram of a second connection method of the functional part 40. The functional part 40 is detachably connected to one end of the housing 10. The functional part 40 includes a functional part 41 and a fixing part 42 connected to the functional part 41. The fixing part 42 is detachably connected to the end of the neck section 12 away from the gripping section 11, so that the functional part 41 and the ultraviolet lamp 31 are arranged opposite to each other along the radial direction of the neck section 12. It should be noted that the ear-picking rod with a disinfection structure in this embodiment is equipped with a variety of functional parts 40, for example, an ear pick and an ear stick for cleaning the ear canal, and for example, a drug delivery accessory for drug introduction. These functional parts 40 are all detachably connected to one end of the housing 10, and the user can choose one to load and unload according to needs. In this embodiment, the functional parts 40 are divided into threaded connection and sleeve connection according to the connection method.

[0047] Since different functional parts 40 are connected to the housing 10 in different ways, in order to realize that the functional parts 40 and the ultraviolet lamp 31 are arranged opposite to each other along the radial direction of the neck section 12, in the embodiment of the present application, the neck section 12 can be a tubular body with an axis passing through, and the inner wall of the neck section 12 is provided with a first convex ridge 15, and the outer wall is provided with a second convex ridge 16, which is used to limit the relative orientation of the functional parts 40. Among them, the first convex ridge 15 is arranged opposite to the ultraviolet lamp 31, and is at a first preset distance from the end of the neck section 12 away from the grip section 11; the second convex ridge 16 is arranged along the axial direction of the neck section 12, and is arranged opposite to the ultraviolet lamp 31. In this embodiment, in order to avoid scratching the ear canal, the second convex ridge 16 is arc-shaped.

[0048] See also Figure 4 and Figure 6 , Figure 6 It is a partially enlarged schematic diagram of the first connection mode of the functional part 40. As a feasible implementation mode, the functional part 40 is spirally connected to one end of the neck section 12. The functional part 40 is also provided with a limiting portion 43. The limiting portion 43 is connected to the fixing portion 42 and is arranged corresponding to the functional portion 41. The fixing portion 42 is provided with an internal thread. One end of the outer wall of the neck section 12 is provided with a thread. During the process of the fixing portion 42 being threadedly connected to the end of the neck section 12 away from the gripping section 11, the limiting portion 43 extends into the neck section 12 and gradually approaches the first convex ridge 15 in the axial direction of the neck section 12, and finally stops at the first convex ridge 15 in the circumferential direction of the neck section 12. Therefore, after the functional part 40 is installed in place, the limiting portion 43 and the first convex ridge 15 stop each other in the circumferential direction of the neck section 12, so that the functional part 40 and the ultraviolet lamp 31 are arranged opposite to each other along the radial direction of the neck section 12.

[0049] See also Figure 5 and Figure 7 , Figure 7It is a partial cross-sectional schematic diagram of the second connection method of the functional part 40. As another feasible implementation method, the functional part 40 is sleeved on one end of the neck section 12, and the fixing part 42 is provided with a receiving groove 44, and the receiving groove 44 is arranged corresponding to the functional part 41. After the fixing part 42 is sleeved on the end of the neck section 12 away from the gripping section 11, the receiving groove 44 cooperates with the second ridge 16, so that the functional part 40 and the ultraviolet lamp 31 are arranged opposite to each other along the radial direction of the neck section 12.

[0050] In general, in the ear cleaning rod with a disinfection structure of the embodiment of the present application, the disinfection structure 30 is integrated with the main body of the ear cleaning rod to form an integrated design, so as to improve the stability and durability of the disinfection structure 30, optimize the position of the ultraviolet lamp 31 in the disinfection structure 30 to ensure a more effective disinfection coverage, and optimize the working mode of the ultraviolet lamp 31 in the disinfection structure 30 to be suitable for different disinfection scenarios.
