<p>PROBLEM TO BE SOLVED: To surely pick earwax in spite of the existence of downy hair inside an external auditory canal by constituting an ear cleaning appliance by means of vapor-depositing diamond powder in a cleaning body. SOLUTION: In the ear cleaning appliance 1, helical and continuous recessed parts 7 progressing forward and backward with an axial line 5 as the common one are formed in a columnar shape body 6 by a cleaning body 4 and the cross section of the parts 7 is made to be rectangular. Besides, diamond powder is vapor-deposited in the cleaning body 4, the corner parts 8 forming the continuous recessed part 7 are made to work as a blade by rotation-scanning the ear cleaning appliance 1 and downy hair on the external auditory canal is cut together with the rotary scanning of the appliance 1 by the angle parts 8. The cut downy hair is stored in the part 7 of the cleaning body 4. Then the tool 1 is slowly moved and cut downy hair is discharged to the outside of the external auditory canal together with earwax.</p> |
