The invention relates to a rotary airflow nozzle for cleaning the optical elements of medical diagnostic device. The invention is formed by one cylinder element, wherein, a pipe chamber is arranged inside the cylinder element; one end of said pipe chamber is connected to the compression air container via valve; the front end of cylinder element has at least three fumaroles while the inner end of fumaroles are connected to the pipe chamber and the outer ends of fumaroles are arranged on the front end surface of said cylinder element; each axis of outlet of fumaroles forms a angle of 0-45 degrees with the front end surface of cylinder element while the projection of said axis is tangent with one round of said front end surface while the center of said round is on the axial line of cylinder element. The invention utilizes at least three fumaroles to enlarge the action area of air flow which can flow outside the fumaroles along several tangents of said round. When rotating the compression airflow nozzle, the dust on the surface of optical element can depart the optical element along said tangent to realize the ideal cleaning effect. |
