The upper base (2) has arranged therein a separator (62), which is connected at the bottom to a pressure groove (63). The upper base (2) has arranged thereon a hollow tube exterior connector (10) matching a suction tube (131). The hollow tube (19a) and a cavity (9) on one side of the separator (62) are interconnected via conduit (18), or, the hollow tube (19a) is extended for about 8 centimeters to form a mouthpiece. The upper base (2) has arranged in the cavity (9) thereof a filter (121). The base (1) is provided with an external base cover (72) which covers a press-button (5a) so as to reduce air flow into the cavity (9).
