The implementation scenario is specifically as follows: put into patient's oral cavity with the hollow pole 20 of rectangle during drilling, miniature negative pressure pump 15 work makes the inside negative pressure that produces of collecting bottle 18 through first hose 16, make the inside accumulated liquid in patient's oral cavity pass through first through-hole 30 under the negative pressure effect, the hollow pole 20 of rectangle and second hose 21 get into the inside collection of collecting bottle 18, guarantee the normal clear of drilling work, prevent that liquid overflow mouth cavity from making dirty patient's clothing, patient's comfort level is high, because metal design hose 19 can be crooked at will, so the hollow pole 20 of rectangle also can be in patient's oral cavity when shell 1 removes, after work, it can be to the inside clearance of collecting bottle 18 to screw out collecting bottle 18, this embodiment has specifically solved the inside accumulated liquid in the oral cavity among the prior art and has hindered the going on of drilling work easily, and the easy overflow mouth cavity makes dirty patient's clothing, patient's comfort level is lower problem.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
