The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 to 4, a smoke aspirator according to an embodiment of the present invention includes a mounting frame 1, a suction bottle 2, a suction tube 3, a filter 4, and a suction head 5; the suction bottle 2 is arranged on the mounting rack 1, and the suction bottle 2 comprises a first suction bottle 21 and a second suction bottle 22; the suction tube 3 comprises a first suction tube 31, a second suction tube 32 and a third suction tube 33, one end of the first suction tube 31 is used for connecting negative pressure equipment, the other end of the first suction tube 31 is positioned in the first suction bottle 21, one end of the second suction tube 32 is positioned in the first suction bottle 21, the other end of the second suction tube 32 is positioned in the second suction bottle 22, the second suction tube 32 is connected with the one-way valve 6, and one end of the third suction tube 33 is positioned in the second suction bottle 22; the filter 4 is connected with the other end of the third suction pipe 33, and filter cotton 41 is detachably arranged in the filter 4; the suction head 5 is used for absorbing smoke, and the suction head 5 is connected to the filter 4 through a connection pipe 51. Wherein, this check valve 6 can be located first suction bottle 21, and traditional check valve is blockked up by the tiny particle in the smog easily, leads to whole suction to descend, influences smoking effect. The one-way valve is arranged on the pipeline.
Thus, the utility model relates to a smoke suction apparatus, when using, negative pressure equipment work to make suction head 5 produce suction, suction head 5 absorbs the smog that the electrotome in the operating room cut skin and produced, this smog gets into filter 4 through connecting pipe 51, the filter pulp 41 in the filter 4 is effectively filtered the tiny particle in the smog, then this smog is through the third suction tube 33 get into the second suction bottle 22 in, then through the second suction tube 32 get into first suction bottle 21, export to the external world after finally through first suction tube 31. As the smoke is filtered by the filter cotton 41, fine particles in the smoke are filtered, so that the filtered smoke is not easy to block the one-way valve 6 when passing through the one-way valve 6, and the suction head 5 keeps strong suction force. Meanwhile, after the filter 4 is used for a period of time, the filtering effect of the old filter cotton 41 is not good, and at this time, the old filter cotton 41 can be taken out and replaced by a new filter cotton 41, so that the filter 4 keeps a good filtering effect and can filter fine particles in smoke.
The negative pressure device connected to the first suction pipe 31 is an existing device, and is a prior art device capable of generating negative pressure so as to suck the smoke and discharge the smoke to the outside or to a smoke processing center for further processing.
Optionally, the filter 4 includes an upper cover 42 and a lower cover 43, a receiving cavity 431 is formed in the lower cover 43 for receiving the filter cotton 41, and the lower cover 43 is screwed with the upper cover 42. By arranging the upper cover 42 and the lower cover 43, when the filter cotton 41 needs to be replaced, the upper cover 42 is only required to be rotated to separate the upper cover 42 from the lower cover 43, so that the old filter cotton 41 can be conveniently taken out, a new filter cotton 41 is put in, and finally the upper cover 42 is rotated in the opposite direction to connect the upper cover 42 with the lower cover 43.
