Water leakage prevention straw and water cup blowout prevention and water inhaling prevention structure

Abstract

The invention discloses a water leakage prevention straw and a water cup blowout prevention and water inhaling prevention structure. The water leakage prevention straw comprises a pipe body and a water blocking valve, wherein the pipe body can be elastically deformed under the extrusion of external force, the water blocking valve is arranged in the pipe body, the water blocking valve comprises atleast two sealing pieces, the edge of one side of each sealing piece is connected to the inner wall of the pipe body, the other edges of the sealing pieces are mutually contacted and pressed, and thethicknesses of the sealing pieces are gradually increased from one side close to the center of the pipe body to one side connected with the inner wall of the pipe body. According to the water blockingvalve structure, the strength of the sealing pieces and the strength of the joint of the sealing pieces and the pipe wall can be improved, the resilience force of the sealing pieces is better, the service life is longer, the problem that the function of the sealing pieces is lost due to repeated bite and water drinking of infants is solved, particles and fragments generated by breakage or fallingof the sealing pieces are reduced or eliminated, and the purposes of protecting the health of the infants, preventing splashing during cover opening and preventing liquid from flowing out when the upper cover is transversely placed, inverted and shaken during opening are achieved.

Description

technical field [0001] The invention relates to the technical field of water cups, in particular to a leak-proof water straw and a water cup anti-spray and anti-choking structure. Background technique [0002] In order to prevent the water from splashing or flowing out when the water cup is placed horizontally, upside down or shaken, the existing water cup straw needs to be provided with a V-shaped water blocking valve in the straw, such as Figure 1-Figure 3 As shown, the V-shaped water blocking valve 02 is composed of two downward-sloping D-shaped sealing sheets oppositely arranged, and the straight sides of the two D-shaped sealing sheets are in contact with each other and pressed against each other. When drinking water, just gently squeeze the mouth of the straw 01, and the mouth of the straw 01 will be deformed, so that the D-shaped sealing pieces that were originally in contact with each other are separated from each other, and the V-shaped water blocking valve 02 will ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing V-shaped water blocking valve has been chewed and drank by children many times. Because of its low structural durability, the V-shaped water blocking valve is easily damaged after a period of use, resulting in water leakage at the drinking mouth. It needs to be replaced by accessories. Solve, bring troubles to users, affect user experience
