[0030] The spherical elastic diaphragm 6 is provided with radial cuts extending from the center of the diaphragm outward; when the through hole of the cylindrical opening and closing valve 3 is rotated to a position through from top to bottom, it corresponds to the position of the suction nozzle 21 and the position of the radial cut, and the edge of the through hole is in contact with the spherical elastic diaphragm 6; the through hole can completely cover the radial cut, and when the cylindrical opening and closing valve 3 is rotated so that the through hole is in contact with the radial cut of the spherical elastic diaphragm 6, the beverage is inhaled. When it is necessary to close, the cylindrical opening and closing valve 3 is rotated, and the edge of its through hole and the cut of the spherical elastic diaphragm 6 form a circular arc tangential motion to squeeze out the residual beverage liquid. The spherical elastic diaphragm 6 is made of food-grade or pharmaceutical-grade rubber, silicone or elastic plastic material.

[0031] like Figure 5 As shown, the radial cuts in this embodiment are composed of three, top-connected, evenly distributed, equal-length arc cuts along the spherical surface; the aperture of the through hole of the cylindrical opening and closing valve 3 is equal to or slightly larger than the diameter of the circumscribed circle of the radial cuts, and the difference does not exceed 0.5 mm.

The drinker sucks the mouthpiece 2, and the suction force opens the radial incision in the spherical elastic diaphragm 6, and drinks according to the amount. After the suction, the cylindrical opening and closing valve 3 is rotated back to the initial position, and the spherical elastic diaphragm 6 returns to its original state. The radial incision of the spherical elastic diaphragm 6 is in a closed state when it is not subject to suction. The opening and closing of the through hole of the rotating cylindrical opening and closing valve 3 fits with the incision of the spherical elastic diaphragm 6 to form a circular arc tangential motion to squeeze out the residual drink liquid, thereby preventing the contamination of a single bottle of drink from being drunk multiple times. After the suction is finished, the mouthpiece can be rinsed with clean water for drinking again.
