[0017] (4) The fluff brush can clean the earwax on the inner wall of the ear canal. The fine and elastic bristles can better fit the complex curved surface of the inner wall of the ear canal, so that they can penetrate into some small gaps and recesses of the inner wall of the ear canal and clean the earwax hidden therein. The soft bristles of the fluff brush can gently act on the ear canal, avoiding problems such as ear canal skin damage and bleeding caused by excessive force or hard tools, thereby ensuring the safety and effectiveness of the cleaning process.

[0018] (5) The movable cylinder and the cotton sleeve are arranged to allow multiple cleaning and adsorption, so that the ear canal is kept dry after cleaning, preventing inflammation in the ear canal and improving the comfort and effectiveness of ear canal cleaning for the patient.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0022] like Figure 1The ear canal cleaning device shown includes a rotating handle 8, an extension rod 3 connected to the left outer wall of the rotating handle 8, a medication storage cavity 19 and a gel storage cavity 15 inside the rotating handle 8, a medication hole 1 and a medication inlet 2 shared by the rotating handle 8 and the extension rod 3, the medication storage cavity 19 and the gel storage cavity 15 respectively communicating through the medication hole 1 and the medication inlet 2, the rotating handle 8 is connected to an infusion assembly 7, the infusion assembly 7 communicating through the gel storage cavity 15, a piston head 21 slidably connected to the inner wall of the gel storage cavity 15, a pressing rod 17 connected to the right outer wall of the piston head 21, the rotating handle 8 has a movable hole 16, the pressing rod 17 is slidably connected to the movable hole 16, by pushing the pressing rod 17, the ear canal gel in the gel storage cavity 15 is pushed out under pressure, facilitating the application of medication into the ear canal by the staff, the rotating handle 8 is connected to An infusion tube 18 is connected to a drug storage cavity 19. A connecting seat 9 is attached to the outer wall of a rotating handle 8. Two sets of connecting seats 9 are symmetrically arranged. A finger ring 11 is connected to the end of each set of connecting seats 9 away from the rotating handle 8. A telescopic rod 12 is connected to the opposite side of each set of finger rings 11. A limit block 14 is connected to the opposite side of each telescopic rod 12. A spring 13 is sleeved on the outer wall of the telescopic rod 12. The two ends of the spring 13 are connected to the finger ring 11 and the limit block 14, respectively. When a medical staff member inserts their finger into the finger ring 11, the spring force of the spring 13 tightly fits the limit block 14 onto the medical staff member's finger, effectively limiting the finger and preventing the medical staff member from slipping during cleaning or other operations. The telescopic rod 12 can also limit the up and down movement of the limit plate, preventing it from shifting during movement and affecting the clamping effect. A sealing ring 20 is fitted onto the outer wall of the piston head 21. Its elasticity allows it to fit tightly against the cavity wall, forming a continuous seal and effectively preventing gel leakage from gaps. Two sets of connecting seats 9 are each connected to a side rod 10, which is connected to a finger ring 11, providing additional support and distributing force. This makes the force on the finger ring 11 more balanced in all directions, reducing the possibility of instability such as wobbling or shifting due to uneven force. A soft brush 4 is connected to the outer wall of the extension rod 3 away from the rotating handle 8. The soft brush 4 can clean earwax from the inner wall of the ear canal without damaging it. The extension rod 3 is connected to a movable cylinder 6 on its outer wall. A cotton sleeve 5 is fitted on the outer wall of the movable cylinder 6. By sliding the cotton sleeve 5, it covers the front end of the extension rod 3. Then, by rotating the handle 8, the cotton sleeve 5 cleans the inner wall of the ear canal. At the same time, the cotton sleeve 5 absorbs the residual medicine attached to the inner wall of the ear canal, thus keeping the ear canal dry after cleaning, preventing inflammation in the ear canal, and improving the patient's ear canal cleaning comfort and cleaning effect.

[0023] The specific implementation process is as follows:

[0024] Staff members fill the medication and ear canal repair gel into the medication storage cavity 19 and the gel storage cavity 15, respectively. Then, the medical staff inserts their fingers into the finger ring 11, and the limiting plate is pressed onto the fingers by the elasticity of the spring 13 to limit the fingers. When the staff member extends the extension rod 3 into the ear canal, the infusion tube 18 can be connected to the medication and inject the medication into the medication storage cavity 19. The medication is injected into the ear canal through the medication storage cavity 19 and the medication hole 1. After the earwax in the ear canal is soaked and softened, the staff member can rotate the handle 8 to make the bristle brush 4 clean the earwax on the inner wall of the ear canal. After cleaning, push the pressing rod 17 to apply the ear canal gel to the inner wall of the ear canal through the medication hole 2 to prevent inflammation of the inner wall of the ear canal.
