Furthermore, a sliding groove 315 is concavely formed on the surface of the atomizing block 31 facing the mounting opening 111, and the sliding block 52 is slidably disposed in the sliding groove 315; specifically, this atomizing piece 31 forms spout 315 to make sliding block 52 of apron 50 can slide and locate in the spout 315, not only further improve the directional slip of sliding block 52, in order to avoid sliding block 52 slip process to break away from atomizing piece 31, guarantee both sliding fit's stability, in order to further improve sputum discharging equipment 100's usability, this processing and mounting means are comparatively convenient and fast simultaneously. Of course, the slide rail may be disposed on the atomizing block 31, so that the slide block 52 is slidably disposed on the slide rail, and the relative sliding between the slide block 52 and the atomizing block 31 may also be implemented, which may be selected by a person skilled in the art and will not be described herein.

Optionally, a surface of the guide block 51 facing away from the sliding block 52 is concavely formed with a handling groove 511. Specifically, a handling groove 511 is concavely formed on the surface of the guide block 51 facing away from the sliding block 52, so that medical staff can more easily poke the cover plate 50 through the handling groove to slide, the operation difficulty is reduced, and the sliding efficiency of the cover plate 50 is improved. Of course, bumps may be provided on the surface of the guide block 51 facing away from the slide block 52, so as to facilitate the medical staff to move the cover plate 50.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
