A drinking straw with a built-in nanobubble generating mechanism

Abstract

To provide a straw that allows a user to constantly ingest beverages containing nanobubbles without requiring any special operation. [Solution] The straw of this invention sucks fluid into the straw body 1 from the tip 4, while simultaneously taking in air from within the liquid through the hole 5. As the fluid passes through the straw tube and passes through the spiral part 2 inside the straw body 1, the water pressure increases. Once the fluid has passed through the spiral part 2, the water pressure drops suddenly, creating a pressure difference that generates 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] Appearance of the straw [Figure 2] Cross section of a straw [Figure 3] When in use

[0013] Figure 1 shows the appearance, Figure 2 shows the storage state, and Figure 3 shows the fluid flow when in use. When fluid is sucked through the straw, it passes through the spiral part inside the straw, causing the water pressure to increase. Once the fluid has passed through the spiral part, it reaches the inside of the straw tube, causing the water pressure to drop suddenly and creating a pressure difference. In addition, by providing a hole at the tip, air present in the liquid can be taken in, effectively generating nanobubbles. [Explanation of symbols]

Claims

1. A drinking straw for sucking up a beverage from a beverage container, characterized in that a spiral part that generates nanobubbles due to changes in fluid flow rate and pressure differences is located inside the straw 30 mm to 100 mm from the mouthpiece, the spiral part having a pitch of 3 mm to 6 mm and a spiral ridge diameter of 1.1 mm to 2 mm.

2. The drinking straw of claim 1, wherein the drinking straw has one to four holes with a diameter of 0.3 mm to 0.6 mm located 5 to 30 mm from the tip of the drinking straw to promote the generation of nanobubbles.
