The base 1 includes a water tank (not shown), a control component (not shown), and a power component (not shown) disposed therein. In a preferred embodiment of the present invention, the control component and the power component should be separated from the water tank by a necessary waterproof structure. An ear canal 23 is provided inside the earmuff 22, and when the earmuff 22 is covered over the ear, the ear canal 23 can be inserted into the ear canal. A viewfinder tube 24 is provided inside the ear canal 23, and a camera device (not shown) is installed inside the viewfinder tube 24. The camera device can be controlled to move back and forth in a straight line to adjust the focus; the straight line can be referenced to the axis of the ear canal 23. In a preferred embodiment of this invention, the camera device uses wireless signal transmission to transmit the captured audio and video data to a mobile phone or other dedicated wireless audio and video playback device via Bluetooth or a wireless network.

A gear 25 is provided on the output shaft of the drive motor. A rack is provided on the outer wall of the viewfinder tube 24. The gear 25 meshes with the rack, thereby causing the viewfinder tube 24 to reciprocate along a straight line within the earpiece tube 23 under the control of the control component, in order to adjust the focal length of the camera device; the straight line direction can be referenced to the axial direction of the earpiece tube 23.

[0031] Preferred embodiments of this utility model, such as Figure 5 As shown, the handle 21 is composed of two handle housings connected together, and the bottom of the handle 21 is sealed by the cover 212.

[0032] Preferred embodiments of the utility model, for example Figure 1 and Figure 2As shown, the earcup 22 includes an earcup base 221, at least two earcup rings 222, and a connecting ring 223. The ear tube 23 is fixedly mounted on the earcup base 221. The earcup rings 222 are composed of two conical rings with larger diameters connected together. Adjacent earcup rings 222 are elastically connected together to form a corrugated tubular earcup ring assembly.

They are located in the middle of the pipeline separating ring 43, so that the three rings of the air pipe separating ring 433, the water spray pipe separating ring 434, and the water suction pipe separating ring 435 form an electrical wire separating ring 436 with the outer separating ring 431 of the pipeline separating ring 43.

[0042] This invention uses the separator connector 41 and the pipeline separator ring 43 to ensure that the various wires in the ear canal cleaning device are laid out in an orderly, safe and reliable manner, preventing the pipelines from getting tangled and causing adverse effects on each other, and ensuring the stability of the device's operation.

[0043] Preferred embodiments of this utility model, such as Figure 2 and Figure 9 As shown, it also includes at least one gas path heating device 42.

A water circuit heating wire is installed inside the clean water tank. This heating wire is electrically connected to a control component, and the heat generated by the heating wire is controlled by the control component. Under the control of the control component, the clean water pumped into the spray pipe is heated by the water circuit heating wire.

[0045] This invention allows for controllable adjustment of the temperature of the rinsing water and airflow, enabling users to clean their ear canals in a comfortable and relaxed posture while ensuring effective ear canal cleaning and enhancing the user experience.

[0046] In a preferred embodiment of this invention, the ear canal cleaning device further includes a liquid filtration and purification device installed within the base. This liquid filtration and purification device connects a clean water tank and a waste water tank, and can filter and purify the liquid in the waste water tank into clean water suitable for cleaning the ear canal, and then discharge the clean water into the clean water tank.

[0047] Preferred embodiments of this utility model, such as Figures 1 to 3 As shown, the base 1 has a recessed wire receiving cavity 11 with cylindrical walls at its top. A winding seat 12 is located in the middle of the wire receiving cavity 11. The top of the winding seat 12 has a recessed handle cavity with cylindrical walls. The side wall of the winding seat has a wire outlet 122, which is a recessed notch that penetrates the side wall of the winding seat 12. A winding cavity is formed between the inner wall of the wire receiving cavity 11 and the outer wall of the winding seat 12, for leading the wire 13, which connects the components in the base 1 and the components in the handheld part 2, out of the handle cavity from the base. The wire 13 includes an electric wire for electrically connecting the electrical components in the base 1 and the electrical components in the handheld part 2, an air pipe 51, a water spray pipe 52, and a water suction pipe 53. Between the base 1 and the handheld part 2, the electric wire, air pipe 51, water spray pipe 52, and water suction pipe 53 can be independent of each other, or they can be bound together without affecting each other. When the handle 2 is inserted into the base 1, the wire 13 enters the winding cavity from the outlet 133 and winds around the outer wall of the winding base 12. The handle 21 of the handle 2 is inserted into the handle cavity of the winding base. The top edge of the winding base extends outward to form a wire-blocking eave 121, which prevents the wire 13 wound on the winding base 12 from detaching from the top of the winding base 12. This utility model makes the ear canal cleaning device easier to store and display in daily life through the winding base 12 and its related structures, thus improving the user experience.
