The invention relates to an air-returning and water-sealing suction pipe system which is penetrated through a cup cover. The air-returning and water-sealing suction pipe system comprises a suction nozzle part, a retainer ring, a suction pipe part and a cross-shaped sealing film, wherein the suction nozzle part and the suction pipe part are integrally connected; both the suction nozzle part and the suction pipe part are hollow truncated cones; the retainer ring is arranged between the suction nozzle part and the suction pipe part; the cross-shaped sealing film is arranged at the hollow junction between the suction nozzle part and the suction pipe part; the outer part of the suction nozzle part is shaped like a slim groove; the retainer ring is embedded on an insertion port at the inner side of the cup cover, and achieves the effects of air returning and water sealing; loops of the retainer ring are in thick film and thin film structures; and five bulges uniformly distributed are arranged in the retainer ring, and form an air-returning pipeline type air ring. The air-returning and water-sealing suction pipe system combines the functions of air returning and water sealing, and has the characteristics of simple structure, high practicality and convenient operation process.
Description
technical field [0001] The invention belongs to the technical field of straws, and relates to a straw system for returning air to seal water 。 Background technique [0002] The straw is based on the principle of atmospheric pressure. When using it, suck some air against the straw, which will cause the pressure inside the pipe to decrease. In order to balance the air pressure, the atmospheric pressure will force the liquid in the pipe to rise. When the inhalation is stopped, the liquid in the tube drops, and the pressure returns to equilibrium. This is the wonderful principle and application of straws, but the current straws can't play the function of returning air and sealing water, and generally have small holes on the cup surface to play the function of returning air. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a suction pipe system that integrates the function of air return s...
