A drinking straw with a built-in nanobubble generating mechanism

Abstract

To provide a drinking straw with a built-in nanobubble generating mechanism that enables a user to constantly ingest beverages containing nanobubbles through the straw without requiring any special operation. [Solution] Nanobubble generators 2 and 3 are built into straw body 1, and by sucking fluid through straw body 1, when the fluid passes through nanobubble generator 2 or nanobubble generator 3, it passes through clearance section 6 between spiral section 4 of nanobubble generator 2 and spiral section 5 of nanobubble generator 3. The water pressure increases as the fluid passes through spiral section 4 of nanobubble generator 2 and clearance section 6 between spiral section 5 of nanobubble generator 3. After passing through nanobubble generators 2 and 3, the fluid reaches the inside of the tube of straw body 1, where the water pressure drops suddenly, creating a pressure difference and generating nanobubbles.

Description

[Technical Field]

[0001] The present invention relates to a straw for consuming beverages, and more particularly to an improved straw that has the function of generating nanobubbles (or microbubbles) in beverages. [Background technology]

[0002] Regular straws do not have a bubble-generating mechanism and do not contribute to improving the quality or functionality of beverages.

[0003] Nanobubbles are known to contribute to maintaining the flavor of beverages, assisting in sterilization, and promoting absorption.

[0004] However, there is no technology that can stably generate nanobubbles using a portable straw-type structure.

[0006] We propose a technology that uses pressure difference, fluid collision, porous film, and Venturi structure to generate nanobubbles in liquid that is sucked and pressurized through a straw. [Problem to be solved by the invention]

[0007] The straw has a built-in pressure chamber and venturi structure, allowing nanobubbles to be generated naturally by the suction flow of the beverage.

[0008] The material used is highly corrosion-resistant resin or silicone. [Effects of the Invention]

[0009] Users can constantly consume beverages containing nanobubbles through a straw without any special operations.

[0010] It can also be used for medical, nursing care, health and pet purposes. [Means for solving the problem]

[0011] We propose a technology that uses pressure difference, fluid collision, porous film, and Venturi structure to generate nanobubbles in liquid that is sucked and pressurized through a straw. [Brief explanation of the drawings]

[0012] [Figure 1] Parts diagram [Figure 2] Container fitting [Figure 3] When in use

[0013] Figure 2 shows the fluid flow in a storage state before use, and Figure 3 shows the fluid flow in use. When fluid is sucked through the straw, it passes through nanobubble generators 2 and 3, causing the water pressure to increase. After passing through the nanobubble generators, the fluid reaches the inside of the straw tube, where the water pressure drops suddenly, creating a pressure difference that generates nanobubbles.

Claims

[Claim 1] A drinking straw for sucking up a beverage from a beverage container, characterized in that the straw has a foaming mechanism inside that generates nanobubbles by changing the flow rate of the fluid and by a pressure difference.
