Description

Technical Field

[0001] This utility model relates to the field of ear cleaning technology, and in particular to a visual ear canal dryer. Background Technology

[0002] Ear canal cleaning and drying are important parts of daily personal care. A moist environment inside the ear canal easily breeds bacteria, leading to inflammation and other health problems. This is especially true after swimming or bathing, when water accumulates in the ear canal and is difficult to drain naturally, causing discomfort and health risks. Currently, there are ear canal dryers on the market, most of which work by using a miniature fan or air pump to generate airflow into the ear canal to achieve drying.

[0003] However, existing ear canal dryers have significant drawbacks. First, the operation is entirely "blind," as users cannot observe the specific conditions inside the ear canal, such as the location of water accumulation, the degree of earwax (cerumen) blockage, or the health of the ear canal skin. This leads to low drying efficiency and poses a risk of damaging the ear canal mucosa or eardrum due to improper operation. Second, they are functionally limited; most products only have a blowing function and cannot switch between blowing drying and suction cleaning as needed. This makes them ineffective at removing earwax, affecting the drying effect. Third, airflow control is not precise enough, lacking real-time temperature monitoring and constant temperature control mechanisms. This may result in excessively high or low airflow temperatures, affecting comfort and even posing a risk of burns. Additionally, the wind speed adjustment is imprecise, and strong winds may cause user discomfort. Furthermore, the design of the wind shield in existing products often lacks adaptability, making it difficult to fit the ear canal structure of different users or age groups (such as children), posing safety hazards and affecting the sealing effect.

[0004] Therefore, there is an urgent need in the field for an ear canal care device that can overcome the above-mentioned shortcomings and achieve safe, efficient, intuitive and multifunctional ear canal drying and cleaning. Summary of the Invention

[0005] The main objective of this invention is to overcome the shortcomings of existing technologies and provide a visual ear canal dryer. This visual ear canal dryer, through structural optimization and functional integration, offers a safe, efficient, intuitive, and multifunctional integrated solution for ear canal care, possessing significant practical value and market potential.

[0006] The technical solution adopted by this utility model to achieve its technical purpose is: a visual ear canal dryer, including a shell, wherein the shell is connected to a fan hood through a fixing frame; The mounting bracket is fixed to the outer casing, and the camera and ventilation duct are fixed on the mounting bracket; The camera is located inside the air cavity of the hood and is aimed at the air outlet of the ear canal. The camera can capture images of the ear canal through the air outlet and can transmit the images to an external display device. An air pump is fixedly installed inside the housing. The air pump is equipped with an air inlet and an air outlet. The air outlet of the air pump is connected to a ventilation duct through an air pump supply pipe. The air generated by the air pump is discharged into the air cavity through the air pump supply pipe and the ventilation duct, and then discharged through the air outlet in the ear canal.

[0007] Preferably, a circuit control board, a power supply, and a USB charging module are also fixedly installed inside the housing.

[0008] Preferably, a switch button is fixedly provided on the outer casing. The switch button is a gear switch to adjust the air pump's air force.

[0009] Preferably, a switching button is also fixedly provided on the outer casing to control the air pump to blow or suck air.

[0010] Preferably, a flexible tube is provided outside the air outlet of the wind cover, an ear pick is provided on the air outlet of the wind cover, a rubber tube is provided on the camera, the ear pick is fixed to the camera through the rubber tube, and the ear pick extends out from the flexible tube.

[0011] Preferably, the fan cover is configured as a flared structure, movably connected to the fixed frame, and a sealing ring is provided at the connection between the fan cover and the fixed frame.

[0012] Preferably, the ventilation duct is provided with airflow connection ports at both ends, with one end of the airflow connection port extending into the air cavity and the other end extending into the outer casing, and connected to the air pump delivery pipe.

[0013] Preferably, the airflow connection port at one end of the ventilation duct is blocked inside the air cavity, and at least one side hole is opened on the side of the ventilation duct for side exhaust.

[0014] Preferably, one or more airflow channel layers are fixedly disposed inside the air cavity of the wind cover to extend the airflow path and absorb the heat generated by the camera.

[0015] Preferably, the airflow channel layer includes an isolation mesh and an isolation cover; The isolation net is fixedly installed on the outer wall of the camera, and the isolation cover is fixedly attached to the edge of the isolation net.

[0016] Preferably, the side of the shroud has at least one groove.

[0017] Preferably, an infrared light module is fixedly installed inside the air cavity of the wind shroud.

[0018] Preferably, the air outlet side of the hood is provided with at least one small hole.

[0019] Preferably, the air outlet of the hood is provided with a step.

[0020] Preferably, a temperature sensor is fixedly installed inside the air outlet of the shroud, and the temperature sensor is electrically connected to a temperature display via a circuit control board. The temperature display is fixedly installed on the outer casing.

[0021] Preferably, the air pump delivery pipe is divided into two sections, which are connected into one unit by a first heat-conducting pipe. The first heat-conducting pipe is wrapped with a heating element, which is connected to the circuit control board.

[0022] Preferably, a second heat-conducting pipe is provided inside the air cavity, one end of which is connected to a ventilation duct, and the other end of which exhausts air inside the air cavity. A heating pad is fixed outside the second heat-conducting pipe, and the heating pad is connected to a circuit control board.

[0023] Preferably, a heating module is fixedly disposed inside the outer casing, and the heating module is connected to the circuit control board.

[0024] Preferably, the circuit control board is equipped with a constant temperature control module, which enables the visual ear canal dryer to output air at a constant temperature.

[0025] The working principle of this visualized ear canal dryer is as follows: an air pump draws in air through the inlet, and the airflow is delivered to the air chamber of the air hood through the air pump's air supply pipe and ventilation duct, and finally discharged from the ear canal outlet, thus drying the ear canal. The air intake path is controlled by a switch button. The outlet is equipped with a flexible tube and an ear pick. The flexible tube is sealed to the outlet, and the ear pick extends out from the flexible tube to perform cleaning by simultaneously scraping and suctioning. At the same time, a camera fixed on the bracket is located inside the air chamber, aiming at the ear canal outlet to collect real-time images of the inside of the ear canal and transmitting them to an external display device to visualize the operation process.

[0026] It should be noted that switching between the blowing and suction functions can be accomplished by a single air pump or by two air pumps working together. The two air pumps control the airflow and suction separately. The air pump for blowing air is connected to an air supply pipe, which in turn connects to a ventilation duct, leading to the airflow chamber and exiting through the air outlet into the ear canal. The air pump for suction air is connected to an air intake pipe, which in turn connects to a ventilation duct on a fixed bracket, drawing in air through the air outlet within the air chamber. To prevent cross-contamination between the two air pumps, valves can be installed in their respective ventilation ducts. For ease of control, the valves can be installed on the fixed bracket and on the ventilation duct within the air chamber.

[0027] Compared with the prior art, the beneficial effects of this utility model are: This visual ear canal dryer uses a camera positioned inside the air chamber of the shroud, aligned with the air outlet of the ear canal, to transmit real-time images of the ear canal to an external display device. Users can intuitively observe the condition of their ear canal, accurately locate areas of water or dirt, avoid blind operation, greatly reduce the risk of ear canal damage, and improve the safety and accuracy of operation, achieving both visualization and enhanced safety during the process.

[0028] This visualized ear canal dryer features a switchable air pump that allows for seamless switching between blowing and suction cleaning functions. It not only efficiently dries the ear canal but also removes earwax and other foreign objects, meeting users' more comprehensive ear canal care needs and providing a multi-functional solution integrating blowing and suction.

[0029] This visual ear canal dryer features a switch button design that allows for precise adjustment of the air pump's airflow. An integrated temperature control module on the circuit board, combined with multiple heating methods (such as heating modules, heating elements with a first heat pipe, and heating pads with a second heat pipe), along with a temperature sensor and display, achieves constant and real-time monitoring of the outlet air temperature. This effectively prevents burns, ensuring comfort and safety during use, and guaranteeing both comfortable and controllable airflow.

[0030] This visual ear canal dryer features a flared design with a sealing ring, which improves the fit and seal of the ear canal and facilitates easy disassembly for cleaning the lens and air chamber.

[0031] This visual ear canal dryer, with its added steps and other structures, allows the product to be safely adapted to different user groups (such as children) and ear canal shapes.

[0032] This visual ear canal dryer features a side-hole design at the end of the ventilation duct and an airflow channel layer (such as an isolation mesh and isolation cover) within the air cavity. This optimizes the airflow path, extends the contact time between the air and the heating components, improves thermal efficiency, and helps dissipate heat from the camera. The optimized structural design enhances applicability and effectiveness.

[0033] This visual ear canal dryer features an added infrared light module that combines illumination with potential sterilization functions. This visual ear canal dryer features a flexible tube at the air outlet of the air hood, an ear pick attached to the air outlet, and a rubber tube attached to the camera. The ear pick is fixed to the camera via the rubber tube and extends out of the flexible tube. This design achieves a combined effect of physical ear cleaning and negative pressure suction under visual guidance, significantly improving cleaning efficiency and expanding integrated functions to enhance the user experience.

However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0045] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0048] Please see Figure 1A visual ear canal dryer includes a housing 1, to which a fan hood 2 is connected via a mounting bracket 4. The fan hood 2 has a flared structure and is movably connected to the mounting bracket 4. A sealing ring 20 is provided at the connection between the fan hood 2 and the mounting bracket 4. The flared structure of the fan hood 2 facilitates opening and straightening of the ear canal, making it easy to observe the ear canal and blow air. The sealing ring 20 can be fixedly set on the outer ring of the mounting bracket 4 or the inner ring of the fan hood 2 to prevent airflow leakage and ensure concentrated airflow. It also allows for easy disassembly of the fan hood 2, facilitating the cleaning of the camera 3 and the fan hood 2 itself. Because the sealing ring 20 increases the friction between the fan hood 2 and the mounting bracket 4, it better enables the fan hood 2 to be plugged and unplugged onto the mounting bracket 4, increasing the stability of the fan hood 2.

[0049] The mounting bracket 4 is fixed to the outer casing 1. The camera 3 and ventilation duct 19 are fixed on the mounting bracket 4. A rubber tube 21 is fitted onto the camera 3, tightly securing it to the outside. The rubber tube 21 provides elastic fixation for the camera 3, preventing it from loosening or falling off and avoiding it from entering the interior of the outer casing 1, thus improving structural stability. The camera 3 is located inside the air cavity 5 of the fan cover 2 and is aligned with the ear canal outlet 7 of the fan cover 2. The camera 3 captures ear canal images through the ear canal outlet 7 and can transmit the images to an external display device for visual operation.

[0050] An air pump 8 is fixedly installed inside the outer casing 1. The air pump 8 is equipped with an air inlet 13 and an air outlet 14. The air outlet 14 of the air pump 8 is connected to a ventilation duct 19 through an air pump supply pipe 11. Both ends of the ventilation duct 19 are provided with airflow connection ports 12. One end of the airflow connection port 12 extends into the air cavity 5, and the other end extends into the outer casing 1, communicating with the air pump supply pipe 11. The air generated by the air pump 8 is discharged into the air cavity 5 through the air pump supply pipe 11 and the ventilation duct 19, and is discharged through the ear canal air outlet 7. The ventilation duct 19 ensures that the airflow is smoothly introduced from the air pump 8 into the air cavity 5, forming a continuous airflow channel, which makes the overall structure well sealed and prevents air leakage.

[0051] The outer casing 1 also houses a circuit control board 9, a power supply 10, and a USB charging module 23. The circuit control board 9 controls the operation of electronic components such as the air pump 8 and the camera 3, the power supply 10 provides electrical power, and the USB charging module 23 facilitates charging for users and enhances portability.

[0052] Furthermore, in this embodiment, a switch button 15 is fixedly installed on the outer casing 1. The switch button 15 is a gear switch that can adjust the speed and / or air temperature of the air pump 8. The switch button 15 is installed on the surface of the outer casing 1 and connected to the circuit control board 9. Users can adjust the airflow and / or temperature through the gear switch to adapt to different usage needs, thereby improving the comfort and safety of use.

[0053] Furthermore, in this embodiment, a switching button 31 is also fixedly installed on the outer shell 1. The switching button 31 controls the air pump to blow or suck air. The switching button 31 is installed on the surface of the outer shell 1 and connected to the circuit control board 9. The user can adjust the air pump to blow or suck air through the switch, thereby generating positive pressure to dry the ear canal or negative pressure to suck out dirt, integrating blowing and suction. Example 2

[0054] Please see Figure 1 and Figure 2 Based on the above embodiments, this visual ear canal dryer differs from the above embodiments in that: the air pump delivery pipe 11 is divided into two sections, which are connected into one unit by a first heat-conducting pipe 17. A heating element 18 is wrapped around the first heat-conducting pipe 17 and connected to the circuit control board 9. The heating element 18 is used to heat the first heat-conducting pipe 17, thereby heating the flowing air, enabling the air pump delivery pipe 11 to output hot air and improve the drying efficiency of the ear canal.

[0055] The circuit control board 9 is equipped with a constant temperature control module. The constant temperature control module controls the heating element 18 through the control circuit board 9, and can control the heating element 18 to maintain a constant temperature. Thus, the visual ear canal dryer can output air at a constant temperature through the constant temperature control module.

[0056] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 3

[0057] Please see Figure 1 and Figure 3 Based on the above embodiments, this visual ear canal dryer differs from the above embodiments in that: a second heat-conducting pipe 24 is provided inside the air cavity 5, one end of which is connected to the ventilation duct 19, and the other end of which exits the air cavity 5. A heating pad 6 is fixed to the outside of the second heat-conducting pipe 24, and the heating pad 6 is connected to the circuit control board 9. The second heat-conducting pipe 24 is fixedly sleeved on the ventilation duct 19. By heating the airflow through the second heat-conducting pipe 24 and the heating pad 6, the outlet air temperature of the ventilation duct 19 is increased, which can generate hot air in the air cavity 5 and improve the drying efficiency of the ear canal.

[0058] The circuit control board 9 is equipped with a constant temperature control module. The constant temperature control module controls the heating pad 6 connected to the control circuit board 9, and can control the temperature of the heating pad 6. Thus, the constant temperature control module enables the visual ear canal dryer to output air at a constant temperature.

[0059] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 4

[0060] Please see Figure 1 and Figure 4 Based on the above embodiments, this visual ear canal dryer differs from the above embodiments in that: a heating module 16 is fixedly installed inside the outer shell 1, and the heating module 16 is connected to the circuit control board 9. The heating module 16 can be configured as a heater to preheat the air inside the outer shell 1, so that the air pump 8 can directly output hot air after drawing in the air inside the outer shell 1, thereby improving the drying efficiency of the ear canal.

[0061] The circuit control board 9 is equipped with a constant temperature control module. The constant temperature control module controls the heating module 16 through the control circuit board 9, and can control the heating module 16 to maintain a constant temperature. Thus, the visual ear canal dryer can output air at a constant temperature through the constant temperature control module.

[0062] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 5

[0063] Please see Figure 1 and Figure 5 Based on the above embodiments, this visual ear canal dryer differs from the above embodiments in that: the airflow connection port 12 at one end of the ventilation duct 19 inside the air cavity 5 is blocked, and at least one side hole 30 is opened on the side of the ventilation duct 19 for side exhaust. Air is exhausted through one or more side holes 30, avoiding direct airflow, extending the airflow time, increasing the contact area and time between the air and the camera 3, absorbing the heat from the camera itself, and saving energy.

[0064] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 6

[0065] Please see Figure 1 and Figure 6 Based on the above embodiments, the visual ear canal dryer differs from the above embodiments in that: one or more airflow channel layers are fixedly provided in the air cavity 5 of the air cover 2 to extend the airflow path and absorb the heat generated by the camera 3. The airflow channel layer extends the airflow path, allowing the air to more fully absorb the heat emitted by the camera, which can increase the outlet air temperature, save energy and improve comfort.

[0066] The airflow channel layer includes an isolation net 25 and an isolation cover 26. The isolation net 25 is fixedly installed on the outer wall of the camera 3, and the isolation cover 26 is fixedly attached to the edge of the isolation net 25. The isolation net 25 is designed with a mesh structure (for easy ventilation and to isolate dirt), and the isolation cover 26 is designed with a sealed structure such as stickers to block the edge of the isolation net 25, preventing the ventilation duct 19 from blowing air directly into the ear canal outlet 7. This allows the ventilation duct 19 to blow air towards the isolation cover 26, allowing the air to flow laterally within the air cavity 5 before exiting, increasing the airflow and prolonging the residence time of the air inside the air cavity 5. This allows the air to fully absorb the heat from the camera 3. When multiple layers of airflow channels are set, they can be set as a stepped structure, gradually reducing the volume and arranging them towards the ear canal outlet 7 before being fixed on the outer wall of the camera 3.

[0067] Furthermore, in this embodiment, an infrared light module is fixedly installed inside the air cavity 5 of the air cover 2. The infrared light has the functions of sterilization and promoting microcirculation, which improves the health environment of the ear canal while drying. The infrared light module is located between the airflow channel layer and the fixing frame 4, which facilitates direct disinfection after the air is discharged from the ventilation duct 19.

[0068] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 7

[0069] Please see Figure 1 and Figure 6 Based on the above embodiments, the visual ear canal dryer differs from the above embodiments in that: the air outlet 7 of the hood 2 is provided with a step 27 on the outside. The step 27 is set as a stepped extension sleeve, which can be directly sleeved on the outside of the air outlet 7, or installed on the outside of the air outlet 7 by insertion or threaded connection. The step 27 can be safely limited, making it convenient and safe for children to use, and meeting the standards for use in children's ear canals.

[0070] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 8

[0071] Please see Figure 1 and Figure 6 Based on the above embodiments, the visual ear canal dryer differs from the above embodiments in that: the air outlet 7 of the hood 2 is provided with at least one small hole on the front side, which facilitates more comprehensive airflow to dry the ear canal.

[0072] It should be noted that when the small hole is located on the front side of the air outlet 7 and the step 27 is fitted outside the air outlet 7, it will not block the small hole. Example 9

[0073] Please see Figure 1, Figure 6 and Figure 8 Based on the above embodiments, the visual ear canal dryer differs from the above embodiments in that: the air outlet 7 of the hood 2 is provided with a flexible hose 32.

[0074] The flexible tube 32 is fitted outside the air outlet 7 or outside the step 27. The flexible tube 32 can be easily and safely inserted into the ear canal for blowing and suction. The flexible tube 32 can be made of existing thin and soft materials, so that the flexible tube 32 can be inserted into the ear canal without pain. It is also easy to remove and replace when it gets dirty. The air hole is conducive to drying the ear canal by air coming out from multiple directions.

[0075] It should be noted that when the small hole is located on the front side of the air outlet 7 and the flexible hose 32 is fitted outside the air outlet 7, the small hole will not be blocked. Example 10

[0076] Please see Figure 1 , Figure 6 and Figure 8 Based on the above embodiments, the visual ear canal dryer differs from the above embodiments in that: a temperature sensor is fixedly installed on the air outlet 7 of the air cover 2, and the temperature sensor is electrically connected to a temperature display 28 through the circuit control board 9. The temperature display 28 is fixedly installed on the outer shell 1. The temperature sensor monitors the air outlet temperature, and the temperature data can be connected to a mobile phone through the circuit control board 9 to be projected onto the mobile phone screen, or it can be displayed on the outer shell 1 through the temperature display 28, so that the temperature inside the ear canal can be seen when blowing air.

[0077] An air pressure sensor is also fixedly installed inside the air outlet 7 of the fan cover 2. The air pressure sensor is electrically connected to the air pressure display 29 through the circuit control board 9. The air pressure display 29 is fixedly installed on the outer shell 1. The air pressure sensor monitors the air pressure. The air pressure data can be connected to a mobile phone through the circuit control board 9 and then projected onto the mobile phone screen. It can also be displayed on the outer shell 1 through the air pressure display 29, so that the air pressure in the ear canal can be seen when blowing air.

[0078] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 11

[0079] Please see Figure 1 and Figure 7 Based on the above embodiments, the visual ear canal dryer differs from the above embodiments in that: the side of the air cover 2 is provided with at least one groove 22. The groove 22 is opened on the side of the air cover 2 to facilitate the airflow from the ear canal, avoid air pressure accumulation, promote air circulation, and accelerate ear canal drying.

[0080] The solution in this embodiment can be selectively combined with solutions in other embodiments. Example 12

[0081] Please see Figure 1 and Figure 8 Based on the above embodiments, the visual ear canal dryer differs from the above embodiments in that: an ear spoon 33 is provided on the air outlet 7 of the air cover 2, and a rubber tube 21 is provided on the camera 3. The ear spoon 33 is fixed to the camera 3 through the rubber tube 21, and the ear spoon 33 passes through the hose 32.

[0082] By setting an ear pick 33 of appropriate length at the air intake 7, and sealing the air outlet 7 with a flexible tube 32 to form an air duct, the ear pick 33 is fixed to the camera 3 via a rubber tube 21. The ear pick 33 passes through the flexible tube 32, and the camera 3 faces the air outlet 7, the suction port of the flexible tube 32, and the ear pick 33. Because the flexible tube 32 has a thin and soft wall, it can flexibly change according to the shape and size of the ear canal after entering it, and it will not hurt when touching the ear canal wall. It can retain suction power to reach the head of the ear pick, while also leaving space for the camera 3 to frame the shot, which is conducive to visually cleaning earwax in various states, especially earwax that is attached to the ear canal wall. As long as the earwax is removed, it can be directly sucked in by negative pressure.

[0083] Especially for earwax that grows on the ear canal wall, an ear pick is needed to gently remove and suction it, with particularly good results when supported by a visual camera. The flexible tube here can be a separate tube or an integrated tube into the ear canal. It's important to emphasize that this tube is not only soft and safe and comfortable to insert into the ear, but crucially, it forms an airflow channel, essential for generating suction with the ear pick head. Because the air outlet has a certain diameter, and the ear canal is narrow and has a certain depth, there is a distance of 10-20mm between the ear pick head and the air outlet for easier removal. Due to the negative pressure principle, the suction is only applied at the air intake in the ear canal; there is no suction on the ear pick head itself. This utility model features a hose with a sealed air outlet and a hose duct opening approximately 2 mm from the ear pick head. This extends the negative pressure to the ear pick head, making it easier to generate suction around the ear pick head. In addition, the hose is flexible and can deform freely inside the ear canal, making it easy to enter various shaped ear canals without causing pain when touching the ear. It is easy to operate. When the ear pick head removes earwax, the earwax is located at the suction port and can be automatically sucked out directly.

[0084] The ear pick 33 is fixed to the camera 3 via a rubber tube 21, and extends from the air intake 7 and the flexible tube 32. This reduces the wall thickness of the ear pick fixed on the air intake 7, making it easier to operate in narrow ear canals. Moreover, the ear pick 33 can be fixed by inserting it into the connecting rubber tube 21, which also facilitates the replacement and adjustment of the ear pick length, better meeting user needs.

[0085] Users can switch the polarity of the air pump 8 by using the switch button 31, switching it from blowing mode to suction mode, thereby drying the moisture in the ear canal or sucking out earwax.

[0086] When ear canal cleaning is needed, the user uses the ear pick 33 installed at the front of the air outlet 7 to scrape the earwax under the direct view of the camera 3 pointing at the opening of the flexible tube, and the suction function of the flexible tube 32 is used to remove earwax in time. The solution in this embodiment can be selectively combined with solutions in other embodiments.

[0087] The specific usage process of this visual ear canal dryer is as follows: After the device is powered on, the user starts the device via the switch button 15 on the outer casing 1 and can select the fan speed and temperature. Its core power source, the air pump 8, begins to work, drawing in air from the intake port 13. If hot air is required, the drawn-in air flows through one or more heating components, such as the heating module 16, the first heat-conducting pipe 17 encased in a heating element 18, or the second heat-conducting pipe 24 with a heating pad 6 inside the air chamber 5, and is heated. The processed airflow is then transported to the air chamber 5 of the air cover 2 via the air pump delivery pipe 11 and the ventilation duct 19 on the mounting bracket 4.

[0088] The ventilation duct 19 can discharge airflow into the air cavity in a specific direction through its end or side holes 30. Before being discharged, the airflow may further pass through an airflow channel layer composed of an isolation net 25 and an isolation cover 26 to extend its path, uniformize the temperature, and absorb the heat generated by the camera 3 during operation. Finally, the temperature-controlled airflow is concentrated and discharged from the ear canal outlet 7, acting on the ear canal.

[0089] At the same time, the camera 3, which is aimed at the air outlet 7 in the ear canal, starts to work, collecting images of the inside of the ear canal in real time and transmitting them to an external display device through the circuit control board 9, so as to realize full-process visual operation.

[0090] It can be supplemented with an infrared light module for supplemental lighting and sterilization. To ensure safety and comfort, steps 27 can be installed at the air outlets 7 to limit the movement and accommodate different ear canals. The air outlet temperature and pressure can be monitored by built-in sensors and displayed in real time via temperature display 28 and air pressure display 29.

[0091] The grooves 22 on the side of the ear canal 2 help maintain the balance of air pressure inside and outside the ear canal. The entire system is powered by the power supply 10 inside the housing 1, can be charged via the USB charging module 23, and all functional modules are controlled by the integrated circuit control board 9.

[0092] When ear canal cleaning is needed, the user uses the ear pick 33 installed at the front of the air outlet 7 to scrape the earwax under the direct view of the camera 3 pointing at the opening of the flexible tube, and the suction function of the flexible tube 32 is used to remove earwax in time. It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural, procedural, or functional transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
