If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Reference Figures 1 to 4 The ear canal cleaning device of this utility model includes an insertion tube 100, a tail tube 200, a rotating rod 300, an exhaust fan blade, and a sponge head 400. The insertion tube 100 has a cleaning end 111 and a connecting end 121. The side wall of the cleaning end 111 is provided with a plurality of suction ports 112, which extend along the length of the insertion tube 100. The plurality of suction ports 112 are arranged around the center of the insertion tube 100 at intervals. The tail tube 200 is detachably connected to the connecting end 121. A filter screen 210 is provided at the end of the tail tube 200; a rotating rod 300 is pivotally built into the insert tube 100, one end of the rotating rod 300 extends to the cleaning end 111 and is surrounded by multiple blades 310, and the other end is fixedly connected to a drive motor 320, which is built into the tail tube 200; an exhaust fan blade is built into the tail tube 200 and is fixed to the drive rod of the drive motor 320; the sponge head 400 and the end of the cleaning end 111 are detachably connected.

[0031] In use, insert the insertion tube 100 into the ear canal, start the drive motor 320, and drive the rotating rod 300 to pivot. At the same time, the exhaust fan blades fixed to the drive rod of the drive motor 320 swing. At this time, a negative pressure is formed inside the insertion tube 100, and the suction port 112 has an adsorption force, adsorbing the earwax in the ear canal and adhering it to the suction port 112. At this time, the swinging blade 310 breaks up the earwax. The broken earwax is sucked into the insertion tube 100, and after passing through the insertion tube 100, it reaches the filter screen 210, completing the cleaning of the ear canal.

[0032] Furthermore, by rotating the entire ear canal cleaning device, the suction port 112 can be made to fit any part of the inner side of the ear canal, ensuring complete cleaning of the inner side of the ear canal.

[0033] Before inserting the insertion tube 100 into the ear canal, a sponge head 400 is first installed on the cleaning end 111. The sponge head 400 is then moistened before being inserted into the ear canal to moisten the ear canal. The sponge head 400 is then removed, and the cleaning end 111 is inserted into the ear canal for subsequent cleaning.

[0034] In summary, the negative pressure created within the insertion tube 100 by the exhaust fan blades draws earwax into the ear canal through the suction port 112, and the earwax is broken up by the blade 310 and then adsorbed onto the filter screen 210, thus improving cleaning efficiency.

[0035] Specifically, in order to constrain the rotation of the connecting rod 131, a limiting ring 130 is built into the insertion tube 100. The connecting rod 131 is fixed between the limiting ring 130 and the inner wall of the insertion tube 100. The rotating rod 300 passes through the limiting ring 130 and rotates in cooperation with the limiting ring 130.

[0036] In practical use, the detachable connection between the tail tube 200 and the insertion tube 100 allows for the cleaning of earwax on the filter screen 210. To achieve this detachable connection, the tail tube 200 and the insertion tube 100 can be engaged via a snap-fit ​​structure. The rotating rod 300 and the drive motor 320 should also be detachable. Accordingly, in some embodiments, the rotating rod 300 has a slot near the tail tube 200. The drive rod of the drive motor 320 passes through the filter screen 210, and its end has a polygonal insert. The insert is fitted into the slot, enabling the drive motor 320 and the rotating rod 300 to engage in transmission. The slot and insert are engaged, allowing torque to be transmitted to the rotating rod 300 during the rotation of the drive rod of the drive motor 320.

[0037] Preferably, the exhaust fan blades are located between the drive motor 320 and the filter 210 to prevent earwax from contaminating the exhaust fan blades.

[0038] In some embodiments, the insertion tube 100 includes an insertion section 110 and an operating section 120. A cleaning end 111 is disposed at the end of the insertion section 110. One end of the operating section 120 is connected to the cleaning end, and the other end is connected to the tail tube 200. A rotating rod 300 is rotatably mounted in the operating section 120. The diameter of the insertion section 110 is smaller than the diameter of the operating section 120. The operating section 120 is provided for the user to hold the device for convenient use.

[0039] Furthermore, the sidewall of the insertion section 110 is provided with multiple rubber protrusions 113, which are located between adjacent suction ports 112. The insertion section 110 is inserted into the ear canal, and the rubber protrusions 113 are used to clean the inside of the ear canal, causing the earwax to fall out.

[0040] As an embodiment of the above solution, refer to Figure 1 The insertion section 110 and the operating section 120 are fixedly connected by threads.

[0041] As a second embodiment of the above scheme, refer to Figure 2 and Figure 4 Along the circumference of the operating section 120, a groove 140 is provided on the side wall of the operating section 120. One end of the insertion section 110, near the operating section 120, is embedded in the operating section 120, and a slider 150 is provided on its side wall. The slider 150 is embedded in the groove 140 and can slide along the groove 140, allowing the insertion section 110 and the operating section 120 to be rotatably connected. The slider 150 protrudes from the outer wall of the operating section 120. In actual use, after the cleaning end 111 of the insertion section 110 is inserted into the ear canal, the slider 150 is slidable, causing the insertion section 110 to rotate relative to the operating section 120, so that each inner side of the ear canal corresponds to the suction port 112, facilitating the suction of earwax.

[0042] In some embodiments, a lamp holder 500 is fixedly connected to the end of the operating section 120 near the insertion section 110, and a patch LED 510 is fixed to the lamp holder 500. The LED allows medical personnel to easily observe the condition inside the patient's ear canal.

[0043] Specifically, in some embodiments, in order to achieve detachable installation between the cleaning end 111 and the sponge head 400, the end of the cleaning end 111 is arc-shaped, and an insertion hole 1111 is provided at the center of the end of the cleaning end 111. The sponge head 400 is provided with a connecting housing 410, and the connecting housing 410 is provided with a mounting groove 411 that matches the shape of the end of the cleaning end 111. A pin 412 is provided in the middle of the mounting groove 411, and the pin 412 is detachably inserted into the insertion hole 1111.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
