Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, this utility model amasss expectorant bag 2 etc. by suction pipe 1 and negative pressure and forms, described suction pipe 1 and negative pressure are amassed expectorant bag 2 and are connected through, the arrival end of described suction pipe 1 is provided with the hemisphere structure of injection moulding integrated molding, described hemisphere structure is provided with multiple sucker 11, and multiple described sucker 11 is all connected through with suction pipe 1, and the shape of multiple described sucker 11 is regular hexagon, this orthohexagonal diameter is 1 ~ 2mm, is preferably 1.5mm.

Described suction pipe 1 is provided with control valve 3, described control valve 3 is connected through with suction pipe 1, piston 31 is provided with in described control valve 3, this piston 31 is provided with depression bar 32, described depression bar 32 stretches out control valve 3, the external part of this depression bar 32 is arranged with spring 33, one end of described spring 33 is fixedly connected on depression bar 32, and the correspondence position of the other end and control valve 3 lateral wall is connected and fixed; Described depression bar 32 is provided with safety collar 6, and one end of described safety collar 6 is articulated on depression bar 32, and the other end is articulated on control valve 3; The middle part of amassing expectorant bag 2 in described negative pressure is connected with exhaust tube 4, described exhaust tube 4 is also connected with air bag, described air bag comprises trachea 51 and pull bar 52, one end of described pull bar 52 is provided with piston plate 53, one end of this piston plate 53 is stretched in trachea 51, the internal chamber wall of described trachea 51 and the lateral wall sliding connection of piston plate 53; Air outlet valve 5 is provided with the junction of exhaust tube 4 at described trachea 51.
