The invention discloses a spiral expansion type earpick, and belongs to the technical field of
medicine and
hygiene. The device comprises a
handle, a
balloon, a
pressure release valve, a spiral expansion tube and a spoon head, the
handle is of a hollow tubular structure, and two ends are hermetically connected with the
balloon and the spiral expansion tube respectively; the spiral expansion tube is made of elastic
soft materials, spiral protrusions are arranged on the outer wall of the spiral expansion tube, a hollow spoon head is arranged at the top end of the spiral expansion tube, and the wall thickness of the spiral expansion tube is gradually reduced from the
handle end to the spoon head end. The handle, the
balloon, the spiral expansion tube and the inner space of the spoon head jointly form a closed fluid cavity, and the
pressure release valve is arranged on the handle or the balloon. When the earpick is used, the earpick head enters the
ear canal in a small state, the sacculus is extruded to enable the earpick head and the spiral protrusion to expand, the earpick head hooks earwax when the earpick is pulled out, the spiral protrusion scrapes away attachments on the wall of the
ear canal, and the earpick head shrinks and resets after the
pressure release valve is opened. The cleaning device has the advantages of simple structure, low cost, safety in use, thorough cleaning and the like.
