Description

The invention relates to the implementation of a means for drinking and, more specifically, the design of the tube, through which the intake of the beverage from the container is ensured, and can replace conventional tubes in cases where additional mixing and improvement of taste and disinfection due to the action of cavitation inside the bacteria leading to their destruction.

Known tube for cocktails with a set of holes along its length (US 2570366, 1951). The holes can be closed and opened before lowering the duct. When you open any one hole, the first doses of liquid will correspond to the depth selected, depending on the open hole, but as the liquid is taken, the depth level will be variable, which excludes the possibility of taking all the liquid from a given depth.

Known straws for cocktails, which is a tube with a float on it. At the lower end, the tube is bent to some angle (JP 2005013684, 2005). Liquid is taken from the tank through the inlet in the tube. From this it follows that there is only one liquid inlet into the tube, and when liquid is taken through the inlet into the channel, the liquid layers that are above and below the inlet will also be captured due to the turbulence of the flow.

Known straws for cocktails, which is a tube with a float filter at its end (DE 20 2006000080 U, 04.20.2006). When using such straws, the jet entering the hole of the tube collects liquid located throughout its depth, in a cone with a vertex at the end of the tube.

Known straws for cocktails with an ice trap at the end of a straw tube (US 2004118769, 2004). Liquid intake is carried out from an arbitrary depth. The fluid enters the tube through the volume of ice in the trap.

The disadvantages of the known devices is the inability to create turbulence of high intensity and cumulative microjets, which, if present, enrich the drink with free liquid ions useful for the human body, as well as the disinfection of the drink.

Known tube for drinks and medicines with a hollow cylinder and constrictions in the form of compression (WO 2008036885, A47G 21/18, 03/27/2008). However, the known device does not provide the creation of a cavitation chamber with the creation of turbulence of high intensity, but is intended to retain solid undissolved particles in the drink.

A tube with a hollow cylinder, constrictions in the form of crimps and a filter is known (WO2008062241 A1, May 29, 2008), which also does not provide the creation of a cavitation chamber with the creation of turbulence of high intensity, and with the help of the installed filter it solves other problems.

Closest to the proposed is the drinking tube described in RU 2293506, A47G 21/18, 02.20.2007 with a bellows and one or more hollow cylinders. In a known construction, a valve mechanism is used, which, for example, can be formed by extending the tube from which the bellows element is formed.

However, this device does not allow to achieve the effects that are provided by the present invention.

The technical result of the claimed tube design is:

1. Improving the taste of the drink when drinking through the proposed tube. This is achieved by intensive mixing due to the formation of macroturbulent vortices of high intensity and microvortices obtained by the collapse of microcavitation bubbles obtained after the collapse of the caverns formed in the tube. When microbubbles collapse, cumulative microjets are formed with velocities of the order of 1000 m / s and shock local pressures of the order of 10,000 atm.

2. The enrichment of the drink with free liquid ions useful for the human body, the number of which increases significantly due to the cavitation-cumulative effect and the energy released during the collapse of the bubbles.

3. Purification of the drink from harmful bacteria and viruses located in it, due to the action of cavitation inside the bacteria, the formation of hydrogen peroxide. A certain role in the destruction of virus bacteria is played by the evolution of gas from solutions, as well as a sharp change in pressure in the liquid.

4. Reducing the amount of saturated gases in the drink, which leads to the preservation of human health, because saturated gases dissolved in liquids adversely affect human blood vessels, since cavitation of the bubbles of these gases leads to damage to the walls of blood vessels and heart valves.

5. In some cases, it seems possible to reduce the effort required to lift the drink through the tube from the vessels into the oral cavity, even despite the presence of places of resistance of the liquid in the form of clamps. This is explained both by a decrease in the coefficient of resistance of fluid to friction against the wall of the tube with increasing turbulence of the fluid flow, and by splitting the fluid flow into a number of parts, which require less effort to lift.

This result is ensured by the fact that the drinking tube containing one or more hollow cylinders with at least one bellows is characterized in that the tube has at least two constrictions and is made with one or more cavitation chambers to create cumulative microjets formed during the collapse of cavitation bubbles, the chamber being formed by placing throttle devices in the form of washers or nozzles at the ends or walls of the cylinder, obtained by crimping the tube and / or creating a month GOVERNMENTAL thickenings tube walls and / or insertions into pucks or nozzles attached by welding, gluing or crimping.

Additionally, the result is ensured by the fact that the drinking tube contains additional hollow cylinders with diameters equal to or greater than the diameter of the main cylinder;

the inner diameter of one or more cavitation chambers is larger than the inner diameter of the cylinder;

the throttle device is made in the form of a washer having an inner hole without chamfer;

the throttle device is made in the form of a washer having an inner hole with conical or rounded chamfers;

the throttle device is made in the form of a nozzle having a cylindrical middle part and a conical inlet and outlet;

the inner surface of the tube is made rough.

The invention consists in the following.

One or more cavitation chambers are created in a drinking tube with the help of two or more local constrictions, which makes it possible to intensify a number of physicochemical processes in the liquid passing through it, which leads to an improvement in the taste of the drink, enrichment of the drink with free ions useful for the human body, and clear the drink of harmful bacteria and viruses in it, reduce the harmful effects of saturated gases in the drink and in some cases reduce the effort spent drinking the drink through a tube.

The tube must have at least two constrictions 1 (figure 1), forming one or more cavitation chambers 2.

The inner diameter of one or more cavitation chambers 3 may be larger than the inner diameter of the tube.

The narrowing of the tube is a throttle device, which can be made in the form of a throttle washer (Fig.3-11) or in the form of a throttle nozzle (Fig.12-17).

The throttle device can be formed either by crimping the tube (FIGS. 3-5, 12, 13) or using special inserts in the tube (FIGS. 6-8, 14, 15), which can be attached to it by welding, gluing or crimping , and due to local internal thickening of the walls (Fig.9-11, 16, 17).

The throttle washers may have an inner hole without chamfer (Fig. 3, 6, 9), with conical chamfers (Fig. 4, 7, 10) and with rounded chamfers (Fig. 5, 8, 11).

-образный профиль продольного сечения сопла (фиг.13, 15, 17).Throttle nozzles can have a conical inlet and outlet and a cylindrical middle part (Fig. 12, 14, 16) or have a specially selected

-shaped profile of the longitudinal section of the nozzle (Fig.13, 15, 17).

The device operates as follows. Consider Fig. 18.

Nozzle 4 - sections of the tube 6-9, nozzle 5 - sections 10-13, cavitation chamber - section 4-5.

The sections of the tubes 6, 7 and 10, 11 are confusers, respectively, the speed of movement of the drink in them increases. In accordance with the law of conservation of energy, the pressure inside the liquid in these areas decreases. An increase in the flow velocity leads to an increase in the number of vortices inside the flow, i.e., to an increase in its turbulence, and a decrease in pressure inside the fluid leads to the formation of caverns, i.e. bubbles of supersaturated gas vapors dissolved in a liquid.

The largest number of vortices and cavities is formed in the narrowest section of nozzles 7, 8, 11, 12, where the fluid velocity is greatest and the pressure is lowest. With further movement of the liquid, it passes into the expansion sections of the tube 8, 9, 12, 13, i.e. into diffusers, where the fluid velocity slows down and pressure rises. The greatest deceleration of the fluid flow rate and increase in its pressure occur in the cavitation chamber — on the duct section 9, 10. Due to the inhibition of the fluid on the duct section 8, 9 and 12, 13, and especially in the cavitation chamber, the formation of macroturbulent vortices of high intensity and microvortices, obtained by the collapse of microcavitation bubbles. Microcavitation bubbles appeared after the collapse of the caverns formed in the tube in sections 6, 8, 10, 12. When the microbubbles collapse, cumulative microjets are formed with velocities of the order of 1000 m / s and shock local pressures of the order of 10,000 atm, which have a grinding, stirring and dissolving microkinetic effect on the substances that make up the drink. The turbulence and microbubbles formed in the cavitation chamber pass into the next narrowing of the tube — sections 10–13, where the number of vortices and cavities formed increases significantly, which leads to a more intensive process of mixing the liquid as it moves along the tube. With an increase in the number of cavitation chambers, the process of mixing the liquid occurs much more intensively.

In order to increase the intensity of the process of fluid turbulization in the cavitation chamber and to increase the formation of caverns and microbubbles in it, it is recommended to increase friction on the inner surfaces of the chamber (Fig. 19). To this end, it is proposed to place the corrugation - bellows inside the chamber and make the inner surface of the chamber due to special processing. An increase in the roughness of the tube along its entire length behind the cavitation chambers along the course of the liquid will further intensify the process of mixing it.

Thus, as follows from this description, the claimed device during its operation ensures the achievement of the specified technical result.
