[0023] During use, by setting up a cleaning mechanism 5, when the device is started, the cleaning liquid in the cleaning liquid cylinder 4 is pushed into the flushing tube 501. At the same time, the flushing tube 501 in the cleaning mechanism 5 rotates, and the flushing liquid is evenly sprayed into the patient's external auditory canal through multiple water outlets on the surface of the flushing tube 501, thereby improving the uniformity of the device spraying the flushing liquid. At the same time, the flushing tube 501 can clean the stubborn earwax adhered to the external auditory canal through the soft bristles 502 on the surface, thereby improving the cleaning effect of the device on the ear canal.

[0024] In this embodiment, the limit pin 6 is a shoulder column structure, one end of the reset spring 13 is fixedly installed on the shoulder of the limit pin 6, and the other end of the reset spring 13 is fixedly installed on the adapter sleeve 503.
