Description

[0001] CARBONATED WATER MANUFACTURING DEVICE [0002]

More particularly, the present invention relates to a carbonated water producing apparatus for producing carbonated water by mixing water supplied from an external water source and carbon dioxide gas discharged from a carbon dioxide gas cylinder.

Carbonated water is also used to make carbonated beverages, but it is already known to be effective for healthy hair and scalp. Because human hair consists of 80-90% of protein, it is stiff and rough when washed with basic solution of pH 7 or more, but is softened when washed with acidic solution of pH 7 or less. Among acidic solutions, it is known that when washed with a weakly acidic solution in the pH range of PH 4.5 - PH 6.5, it is possible to remove the softest and healthy hair and scalp.

In particular, when perming or dyeing hair, the hair is likely to be damaged to a strong basicity with a pH of 9.0 to 9.3 due to the use of a pharmaceutical or dye. Typical tap water is around pH 7.0. Therefore, tap water is not in good condition to soften hair or maintain health. Hydrogen ion concentration at the time of healthy hair is weak acidity ranging from pH 4.5 to pH 6.5. Therefore, Washing the hair with slightly acidic carbonated water is good for keeping healthy hair. Also, in the hair salon where head spas are dirty, if the pores are clogged, or when the perms or the coloring agent remains on the scalp, the carbonated water adheres to the dirty skin of the carbonic acid so that the dirt of the scalp is cleaned with dirt.

Furthermore, as the carbon dioxide gas is absorbed into the body, the capillary blood vessels are expanded to smooth the blood circulation, and the carbonic acid gas is acidic to form the antibacterial substance, and also to exhaust the waste while penetrating into the skin. These effects will make your skin softer, cleaner, shiny and you can expect to recover from fatigue. In addition, the effects of carbonation, which is beneficial to your health and beauty, are becoming increasingly evident. As a result, the introduction of carbonated water generation devices has been increasing in general households, as well as beauty care companies such as beauty salons.

Conventional carbonated water producing apparatuses have been proposed as a high pressure carbon dioxide gas impinging method, a physical stirring method, and a hollow fiber membrane method.

The micro-bubble-dissolving method is a method of generating water droplets or minute bubbles and causing carbon dioxide gas to collide with the minute bubbles generated thereby to dissolve the carbon dioxide gas in the minute bubbles (refer to the prior patent 1).

The physical stirring method is a method of mixing carbonic acid gas with stirring the water flowing into or staying in the water tank (see the prior patent 2). In this case, the carbonated water producing apparatus may be configured to perform stirring operation using an impeller or a propeller rotating at several tens to several hundreds of RPM.

However, such a conventional carbonated water producing device has a problem that the carbonic acid gas dissolution rate in carbonated water produced by the conventional carbonated water producing device is so low that it can not be satisfactorily used for cosmetic use, and the volume of the device is relatively large, Which caused harm to the beauty of the installation.

Previous Patent 1: Korean Registered Utility Model No. 20-0203336 (Sep. 2000) Prior Patent 2: Korean Patent No. 10-1119370 (Feb. 15, 2012)

The apparatus for producing carbonated water according to the present invention can remarkably increase the carbonic acid gas dissolution rate of the generated carbonated water, but also has a simple structure and miniaturization, thereby minimizing the volume of the apparatus. Accordingly, it is possible to provide a carbonated water producing apparatus which can best satisfy the required dissolution rate and installation appearance when applied to a beauty care shop such as a beauty shop.

FIG. 5 is a cross-sectional view of the apparatus for producing carbonated water according to the present invention, and is a view showing the operation state at the time of gas inequality. FIG. 6 is a cross- 7 is a view showing how water and carbon dioxide gas are mixed by the operation of Fig.

Hereinafter, the operation of generating carbonated water in the carbonated water producing apparatus according to the present invention will be described with reference to FIGS. 5 to 7. FIG.

(1) Operation before carbon dioxide gas delivery

A part of the opening and closing ball 35 is inserted into the inlet 33 by the elastic supporting force applied in the direction of the inlet 33 by the elastic body 37 as shown in Fig. 5 before the carbonic acid gas feeding of the carbonic acid gas supplying part occurs, And is brought into close contact with the tip of the mixing tube (30).

The water inlet 33 of the mixing pipe 30 is shielded by the opening and closing ball 35 so that the water supplied from the external water source through the first connection pipe 40 can not flow into the water inlet 33 do.

(2) Operation when carbon dioxide gas is delivered

6, when the carbonic acid gas starts to flow into the second inlet / outlet 12 side G1 in the state where the inlet 33 is blocked by the opening / closing ball 35 as described above, The opening and closing ball 35 is pushed in a direction away from the inlet port 33 by the pressure of the carbon dioxide gas flowing into the mixing pipe 30 and retracts while the elastic force of the elastic body 37 is overcome.

Accordingly, the opening / closing ball 35 is retracted in the opposite direction K1 of the elastic supporting direction to generate a micro gap between the opening / closing ball 35 and the inlet / outlet 33. Through the micro gap thus generated, The water staying in the pipe 40 starts to flow into the mixing pipe 30. [

At this time, when the water passes through the micro gap and moves to the inner side W1 of the mixing tube 30, the flow velocity is forcibly increased due to the diaphragm action due to the change in cross-sectional area of the flow path (i.e., Minute bubbles are generated and a vortex as shown in FIG. 7 is generated in the mixing pipe 30, so that the dissolution rate of carbon dioxide gas in water is increased.

The water flowing into the mixing pipe 30 through the process described above is mixed with the carbon dioxide flowing through the gas passing hole 31 to perform the mixing action to generate carbonated water.

The generated carbonated water flows to the outflow side C1 through the outlet 34 of the mixing pipe 30 and the third connection pipe 43 connected thereto and is sprayed to the outside so that the user can use the carbonated water.

While the preferred embodiments of the present invention have been described and illustrated above using specific terms, such terms are used only for the purpose of clarifying the invention, and it is to be understood that the embodiment It will be obvious that various changes and modifications can be made without departing from the spirit and scope of the invention. Such modified embodiments should not be understood individually from the spirit and scope of the present invention, but should be regarded as being within the scope of the claims of the present invention.
