Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to an ear canal cleaner for ENT department. Background Art

[0002] An ENT ear cleaner is a medical device used to clean the ear canal and remove earwax and foreign matter. While earwax protects the ear canal, excessive accumulation can lead to blockage and hearing loss, making ear canal cleaning crucial. In recent years, the emergence of smart ear cleaners has made the cleaning process more precise and safer, automatically adjusting the cleaning intensity based on the condition of the ear canal. Furthermore, modern ear cleaners not only effectively remove earwax but also incorporate ear health monitoring features to provide users with personalized ear canal care. With the continuous advancement of technology, ear cleaners will continue to develop in a more intelligent and convenient direction, providing a safer and more accurate cleaning experience. However, care should still be taken to avoid over-cleaning during use to prevent damage to the ear canal or eardrum and ensure ear health.

[0003] After searching, the existing patent announcement number CN222444554U discloses an ear canal cleaner for otolaryngology, including a handle, a cleaning probe is provided on the front end of the inner wall of the handle through a locking assembly, and soft bristles and holes are staggered on the outer surface of the cleaning probe, the cleaning probe is located on the inner wall of one end of the handle and a cross-shaped frame is provided, a micro motor is provided inside the handle, and the output end of the micro motor is connected to the cross-shaped frame; by starting the micro motor and the dual-axis motor, the micro motor drives the cleaning probe to rotate, and the cleaning probe is inserted into the patient's ear canal. When the cleaning probe rotates in the patient's ear canal, the soft bristles clean the residue in the patient's ear canal and separate it from the ear canal skin. The dual-axis motor drives the fan blades to rotate and sucks the residue in the ear canal that has separated from the ear canal skin into the interior of the handle. When the residue passes through the chip guard net, it is blocked by the chip guard net and falls into the interior of the collection bottle and is collected by the collection bottle, thereby achieving the purpose of collecting the residue after cleaning the ear canal.

[0004] However, during the actual use of the above solution: since the device draws air through the fan blades, there is a negative pressure near the filter during the process, thereby sucking out the earwax inside the ear canal through the pipe. During actual use, the actual size of the patient's ear canal does not have a large air circulation space. This causes the above device to cause excessive negative pressure inside the ear canal when in use. Excessive negative pressure may cause discomfort or irritation in the ear canal, and may even cause damage or pulling of the ear canal skin. Excessive suction may also exert uneven pressure on the eardrum, increasing the risk of eardrum damage or perforation. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that excessive negative pressure inside the ear canal may cause discomfort or irritation in the ear canal, and may even cause damage or pulling of the ear canal skin, and to propose an ENT ear canal cleaner.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: An ear canal cleaner for ENT, comprising: a rotating suction component and a storage box which are interconnected, and an air supply tube which is sleeved outside the rotating suction component and connected to the storage box; The portion of the rotary suction assembly protruding from the air supply tube is sequentially provided with a cleaning brush, an opening, and a plurality of cleaning plates, wherein the cleaning brushes are evenly arranged along the circumference of the rotary suction assembly, the opening is used to suck earwax in the ear canal, and the plurality of cleaning plates are evenly arranged along the circumference; An air supply channel is provided on the air supply pipe, and one end of the air supply channel corresponds to the cleaning brush.

[0007] Optionally, it also includes: a second motor, the second motor being disposed in an accommodating space between the air supply pipe and the rotating suction assembly; The rotary suction assembly includes: a suction pipe and a transmission sleeve fixed on the outside of the suction pipe, the transmission sleeve is connected to the second motor, and the opening includes an outer opening opened on the transmission sleeve and an inner opening opened on the suction pipe.

[0008] Optionally, the second motor is fixed to the air supply pipe via a connecting ring.

[0009] Optionally, it also includes: a driving gear connected to an output end of the second motor; a transmission gear, the transmission gear being meshed with the driving gear; a gear ring, the gear ring being meshed with the transmission gear; The transmission ring is fixed on the gear ring, and the transmission ring is connected to the transmission sleeve.

[0010] Optionally, the air outlet end of the suction pipe is inserted into the storage box, an exhaust pipe connecting the inside and the outside is provided on the side wall of the storage box, an exhaust fan is fixed in the exhaust pipe, and a filter is connected to the inside of the exhaust pipe.

[0011] Optionally, it also includes: A cleaning wheel, the cleaning wheel being arranged on the inner side of the filter screen; A first motor, wherein an output end of the first motor is fixedly connected to the cleaning wheel.

[0012] Optionally, it further includes: a protection tube, which is sleeved on the outside of the cleaning wheel, and is provided with a through groove corresponding to the filter screen, and the protection tube has a chip discharge port.

[0013] Optionally, the cleaning brush is made of medical silicone and the cleaning plate is made of polycarbonate.

[0014] Optionally, it further includes: a sealing cover, which is snap-connected to the end of the storage box away from the air supply pipe.

[0015] Optionally, the end portion of the rotating suction assembly away from the storage box is closed.

[0016] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects: In the above scheme, by arranging an air supply tube on the outside of the rotating suction component, the rotating suction component can replenish air into the ear canal through the air supply channel while extracting earwax and air inside the ear canal, thereby balancing the negative pressure, avoiding excessive suction causing discomfort or damage to the ear canal and eardrum, and improving the comfort during use. At the same time, increasing the airflow helps to improve the cleaning effect, especially for dry or sticky earwax, as replenishing air can make the earwax easier to be sucked out.

[0017] By optimizing airflow, suction and performance are enhanced while noise is reduced, providing a quieter user experience. This optimized airflow design also improves device stability, reduces energy waste, and achieves energy savings, extending the device's lifespan. Smoother airflow also reduces wear on internal components, improving device durability.

[0018] By setting a cleaning plate on the other side of the cleaning brush, stubborn earwax can be cleaned. The physical action loosens and removes hardened or dried earwax, enhancing the thoroughness of cleaning while reducing attraction to the ear canal and the risk of damage to the ear canal and eardrum. It can help separate earwax from the ear canal wall, making it easier to suck out, thereby improving cleaning efficiency and reducing the need for frequent cleaning, avoiding excessive stimulation of the ear canal. The cleaning plate design can also better adapt to different types of earwax, improving the versatility and practicality of the device, ensuring safer, gentler and more efficient cleaning of stubborn earwax. By arranging a filter at the outlet end of the rotating suction component, air and earwax can be separated. The filter cleaning component cleans the filter and pushes the earwax out of the protective tube at the same time, thereby preventing earwax from accumulating near the negative pressure area of the cleaning wheel and keeping the interior of the cleaner clean. This reduces the risk of earwax accumulation affecting cleaning efficiency and ensures a cleaning effect every time it is used. By placing the filter inside the protective tube, the chance of earwax coming into contact with the filter is reduced, minimizing the risk of filter clogging. This maintains the cleaner's suction force and improves cleaning efficiency. Because the filter is less susceptible to earwax clogging, the device maintains efficient operation, extending its lifespan and reducing the frequency of maintenance and replacement. This design also reduces the risk of earwax spreading within the cleaner, preventing secondary contamination and ensuring a more hygienic and thorough cleaning each time.

[0029] like Figures 1 to 7 As shown, an embodiment of the present invention provides an ear canal cleaner for otolaryngology, comprising: a rotating suction assembly and a storage box 1 that are interconnected, and an air supply tube 4 that is sleeved outside the rotating suction assembly and connected to the storage box 1; a portion of the rotating suction assembly that protrudes from the air supply tube 4 is sequentially provided with a cleaning brush 31, an opening, and a plurality of cleaning plates 32, the cleaning brushes 31 being evenly arranged along the circumference of the rotating suction assembly, the opening being used to suck earwax in the ear canal, and the plurality of cleaning plates 32 being evenly arranged along the circumference; an air supply channel 41 is provided on the air supply tube 4, one end of which corresponds to the cleaning brush 31 (see Figure 2 ).

[0030] The workflow of the technical solution provided by the present invention is as follows: First, insert the rotary suction assembly and the air supply tube 4 into the innermost part of the ear canal; Then, the air inside the ear canal is extracted by rotating the suction assembly. During this process, the external air is transported into the ear canal through the air supply channel 41 to balance the negative pressure generated by the air extraction, thus forming a circulation. By rotating the suction assembly, the cleaning brush 31 and the cleaning plate 32 are driven to rotate synchronously, and the earwax inside the ear canal is cleaned by the cleaning brush 31, while the stubborn earwax inside the ear canal can be cleaned by the cleaning plate 32.

[0031] In the above scheme, by arranging an air supply tube 4 on the outside of the rotating suction component, the rotating suction component can replenish air into the ear canal through the air supply channel 41 while extracting earwax and air inside the ear canal, thereby balancing the negative pressure, avoiding excessive suction causing discomfort or damage to the ear canal and eardrum, and improving the comfort during use. At the same time, increasing the airflow helps to improve the cleaning effect, especially for dry or sticky earwax, the replenishing air can make the earwax easier to be sucked out.

[0032] By optimizing airflow, suction and performance are enhanced while noise is reduced, providing a quieter user experience. This optimized airflow design also improves device stability, reduces energy waste, and achieves energy savings, extending the device's lifespan. Smoother airflow also reduces wear on internal components, improving device durability.

[0033] By providing a cleaning plate 32 on the other side of the cleaning brush 31, stubborn earwax can be cleaned. Hardened or dried earwax can be loosened and removed through physical action, thereby enhancing the thoroughness of cleaning and reducing the attraction to the ear canal, thereby reducing the risk of damage to the ear canal and eardrum. It can help separate earwax from the ear canal wall, making it easier to suck out earwax, thereby improving cleaning efficiency, and reducing the need for frequent cleaning, avoiding excessive stimulation of the ear canal. The design of the cleaning plate 32 can also better adapt to different types of earwax, improving the versatility and practicality of the equipment, and ensuring that stubborn earwax is cleaned more safely, gently and efficiently.

[0034] See also Figures 5 and 6 In one embodiment provided by the present invention, it further includes: a second motor 21, which is arranged in the accommodating space between the air supply pipe 4 and the rotating suction assembly; the rotating suction assembly includes: a suction pipe 33 and a transmission sleeve 3 fixedly mounted on the outside of the suction pipe 33, the transmission sleeve 3 is connected to the second motor 21, and the opening includes an outer opening opened on the transmission sleeve 3 and an inner opening opened on the suction pipe 33.

[0035] The second motor 21 is used to provide power for suction, and the transmission sleeve 3 is used to drive the cleaning brush 31, the cleaning plate 32 and the suction tube 33 to rotate. The suction tube 33 can accelerate the collection of earwax during the rotation process.

[0036] In one embodiment of the present invention, the second motor 21 is secured to the air supply pipe 4 via a connecting ring 2. The connecting ring 2 protects the second motor 21 and other components. Furthermore, the connecting ring 2 connects the air supply pipe 4 and the storage box 1 on either side, allowing for quick connection and removal.

[0037] In one embodiment provided by the present invention, it also includes: a driving gear 22, the driving gear 22 is connected to the output end of the second motor 21; a transmission gear 23, the transmission gear 23 is engaged with the driving gear 22; a gear ring 24, the gear ring 24 is engaged with the transmission gear 23; a transmission ring 25, the gear ring 24 is fixed on the transmission ring 25, and the transmission ring 25 is connected to the transmission sleeve 3.

[0038] The power is transmitted to the transmission sleeve 3 through the above transmission structure.

[0039] See Figure 3 、 Figure 4 、 Figure 7 and Figure 8In one embodiment of the present invention, the outlet end of the suction tube 33 is inserted into the storage box 1. An exhaust pipe 11 is provided on the side wall of the storage box 1, connecting the inside and the outside. An exhaust fan 12 is fixed inside the exhaust pipe 11. A filter 14 is connected to the inside of the exhaust pipe 11. In other words, the filter 14 is located at the outlet end of the rotating suction assembly. The exhaust fan 12 provides power for the suction of the suction tube 33. At the same time, the filter 14 filters the air in the suction tube 33, separating the earwax from the air, leaving the earwax inside the filter 14. The filtered air is then discharged from the cleaner.

[0040] In one embodiment of the present invention, the cleaning wheel 16 is further provided. The cleaning wheel 16 is disposed inside the filter 14. A first motor 15 is fixedly connected to the output end of the first motor 15. The first motor 15 drives the cleaning wheel 16 to scrape the earwax inside the filter 14 and disperse it in the storage box 1, thereby preventing the filter 14 from being clogged.

[0041] By arranging a filter 14 at the outlet end of the rotating suction component, air and earwax can be separated, and the filter 14 cleaning component cleans the filter 14 while pushing the earwax out of the protective tube 13, thereby avoiding earwax accumulation near the negative pressure area of the cleaning wheel 16 and keeping the inside of the cleaner clean. This reduces the risk of affecting the cleaning efficiency due to earwax accumulation and ensures the cleaning effect each time it is used.

[0042] In one embodiment provided by the present invention, it also includes: a protective tube 13, which is mounted on the outside of the cleaning wheel 16, and is provided with a through groove corresponding to the filter screen 14. The filter screen is arranged in the through groove. Moreover, the protective tube 13 has a chip discharge port for discharging the earwax scraped from the filter screen 14 from the protective tube 13 to the storage box 1 through the chip discharge port.

[0043] By placing the filter 14 inside the protective tube 13, the probability of earwax coming into contact with the filter 14 is reduced, reducing the risk of filter 14 clogging, maintaining stable suction, and improving cleaning efficiency. Because the filter 14 is less likely to become clogged by earwax, the device can maintain efficient operation, extending its service life and reducing the frequency of maintenance and replacement. This design also reduces the risk of earwax spreading within the cleaner, preventing secondary contamination and ensuring a more hygienic and thorough cleaning each time.

[0044] In one embodiment provided by the present invention, the cleaning brush 31 is made of medical silicone. Its softness and comfort can avoid damage to the eardrum and ear canal skin, providing a more comfortable cleaning experience. At the same time, medical silicone has strong anti-allergic properties, reduces skin irritation, and is suitable for use on sensitive skin. In addition, the high temperature resistance and corrosion resistance of silicone make it stable and hygienic during the disinfection process, and it is not easy to breed bacteria, which helps to prevent ear canal infection. Its high transparency makes it easy to observe the cleaning effect, meets the needs of different ear canal shapes, and is particularly suitable for children and the elderly. Finally, medical silicone is environmentally friendly and recyclable, and meets modern environmental protection standards. Accurate; the cleaning plate 32 is made of polycarbonate, which has high strength and toughness and can withstand a certain amount of pressure, ensuring the durability and stability of the cleaning plate 32 during use. Its transparency makes it easy for doctors or users to observe the cleaning effect and ensure the precise operation of the cleaning process. At the same time, the lightweight nature of polycarbonate reduces the weight of the tool and improves the comfort of use. The material also has good heat resistance and chemical resistance, can withstand high-temperature disinfection and resist the corrosion of cleaning agents, maintaining the hygiene and long-term stability of the cleaning plate 32. Its smooth surface and no sharp angle design reduce irritation to the ear canal and ensure safety during the cleaning process.

[0045] In one embodiment provided by the present invention, it further includes: a sealing cover 17, which is engaged with the end of the storage box 1 away from the air supply pipe 4, and the end opening of the storage box 1 is sealed by the sealing cover 17.

[0046] In one embodiment provided by the present invention, the end portion of the rotating suction assembly away from the storage box 1 is closed to avoid the formation of negative pressure inside the ear canal and damage to the eardrum.

[0047] It should be noted that the rotation and suction functions of the rotating suction component can be controlled independently of each other. That is to say, during the cleaning process, a part of the earwax is directly sucked into the rotating suction component through the opening, and is transported to the inside of the storage box 1 for storage under the suction action. If there is any earwax remaining, the rotating suction component can be controlled to stop rotating, and only the suction function can be used to absorb and clean the remaining earwax.

[0048] Furthermore, the air supply pipe 4 is sleeved on the outside of the transmission sleeve 3, and sealing rings are provided at both ends of the air supply pipe 4. By providing sealing rings between the transmission sleeve 3 and the air supply pipe 4, the overall air tightness of the equipment is improved.

[0049] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
