Description

The present invention relates to a reaction vessel of casting or extrusion molded product hydrogen generator bath and drinking the reaction metal body thick and was immersed in an aqueous solution of citric acid to generate hydrogen as a magnesium and magnesium alloys is there.

  Conventionally, as a method for generating hydrogen for bathing and drinking purposes without using electricity, there has been a method of generating hydrogen by immersing a metal body of magnesium and a magnesium alloy in a reaction vessel containing the aqueous solution. However, in the present invention, the above-mentioned reaction vessel will be described with emphasis, so the details of the chemical reaction formula relating to hydrogen generation will not be touched basically except those necessary for the explanation of the present invention. This is because the details of these chemical reactions are widely known.

  Some of the above reactive metal bodies are processed into powder and immersed in water to generate hydrogen in a short time. However, these are disposable and are not considered as the technical object of the present invention. Targeting the reaction vessel using the reaction metal body having a thick plate shape, or a type that is thick and has a complicated cross-sectional shape in order to increase the surface area, and is used repeatedly. State.

  Although there are several product examples, the reaction vessel is deeply related to the shape of the reaction metal body, and will be described from its shape. A typical example of the reaction metal body is a so-called Baumkuchen-like perforated columnar body of a Western confectionery that is divided into a plurality of lengths. This is hereinafter referred to as a reaction metal body core. The plurality of reaction metal cores processed in this way are cylindrical, and the reaction metal cores are perpendicular to the engaging portion provided on the flat bottom of the reaction vessel made of resin. To be paid. This reaction metal core is obtained by extrusion molding, and its cross-sectional shape is a hollow, generally fan-shaped columnar shape having complicated irregularities, cut at right angles to a required length. The reason for this is to obtain an increase in the surface area of the reactive metal core and to make it easier to handle because it is sometimes necessary to remove the oxide film and dirt. Magnesium is a light metal, but it is considerably heavy if the reaction metal body is integrated without being divided. In order to stably hold the core of the reaction metal body vertically, a lower curved enclosure that can drop the lower part of the core of the reaction metal body and the inside of the core of the reaction metal body It had curved locking ribs that contacted and supported.

  Further, in another product example, a low-curved enclosure that can drop the entire circumference or part of the lower part of the core of the reaction metal body, or the curved surface that can be supported inside the reaction metal body core. In some cases, a slight step is provided on the inner side of the locking rib to float and support the bottom surface of the reaction metal core.

  In addition, although it is not a technical object of the present invention, it should be noted that the reaction vessel has a lid. Some drinkable hydrogen water can be opened and closed, but this is a spout. Some used for baths have a detachable lid having a reverse funnel-shaped opening at the top of the reaction vessel. If there is no such narrowed structure, bubbles will rise as hydrogen is generated, and at the same time, convection will occur due to some reaction heat, so that the aqueous solution in the reaction vessel will enter the bath water. It is provided for the purpose of preventing the hydrogen production from weakening due to the sudden dilution. This is to explain the complex movement of the aqueous solution in the reaction vessel.

  Other than that, the above-mentioned aqueous solution is put into an existing covered pitcher with a spout, for example, and the reaction metal body core is housed in a cylindrical container with a bottomed lid and a plurality of holes. Some are installed. Also in this case, the method of locking the reaction metal body was almost the same as the above-described means.

Japanese Patent No. 4326577 Model 3151576

  As described in the prior art, in most products, the bottom of the reaction metal core is in contact with the bottom of the reaction vessel, so that the surface area for the reaction is reduced accordingly.

  In addition, a low curved enclosure that can drop the entire circumference or part of the lower part of the reaction metal body core, or a curved engagement rib that can be supported on the inner side where the reaction metal body core contacts is slightly There was also a thing which provided a level difference and floated and supported the bottom part of the above-mentioned reaction metal body core, but since the above-mentioned reaction metal body core is thinned every time it reacts for hydrogen generation, If the thickness of the reaction metal core becomes thin, the reaction metal core cannot be supported by the step and falls to the bottom of the reaction vessel to directly contact with it, so that the surface area for the reaction also decreases.

  Further, the movement of the aqueous solution during hydrogen generation is complicated by the presence of the reactive metal core. There are upward flow due to the generated hydrogen bubbles and convection due to reaction heat, but in some parts it stays and turbulence occurs in the part, and the concentration of the aqueous solution varies. However, there was a problem that the purpose of repeatedly generating hydrogen stably could not be achieved.

  Furthermore, since the bottom surface of the reaction metal core is in contact with the bottom of the reaction vessel, magnesium hydroxide is produced because it remains in the gap by capillarity even if the residual liquid is drained after use. When these stuck to the gaps and the above aqueous solution was put next time, it was not possible to prevent the black film pieces that were peeled off without being dissolved and soiling the hot water in the bathtub.

  In order to solve the above-mentioned problems, the bottom of the reaction vessel and the bottom end face of the reaction metal body core are slightly floated. If there is a locking rib of the mold, the reaction metal core is easy to be stabilized even if it is thin. In order to secure an effective surface area, a plurality of upward ball feet may be provided on the bottom of the reaction vessel to form a support. This is because a ball foot makes point contact, and since there are no corners or intersections of the rising parts as in the rib structure, the reaction residue hardly remains and cleaning after use is easy. In this way, a chemical reaction equivalent to the upper end face of the reaction metal core can be obtained, and an appropriate gap can be formed at the bottom, so that the aqueous solution can easily circulate in the reaction vessel within a certain time. Stable and smooth hydrogen production can be expected. In addition, abnormal partial meat thinning can be prevented.

  If a gap is provided between the bottom of the reaction vessel, the bottom of the reaction metal core and the ball foot, there is no problem in circulation, and incomplete reaction due to retention of the aqueous solution can be avoided.

  Further, the ball foot is installed in accordance with the cross-sectional shape of the reaction metal core, but is located at the center of the thickness of the continuous cut surface of the reaction metal core. This can be supported stably for a long period of time because it is used in combination with a curved locking portion that can be supported inside the reaction metal core.

  As described above, the present invention has a structure in which the bottom part in the reaction vessel and the bottom end surface of the reaction metal body core are not brought into contact with each other and are slightly floated by point contact with the ball foot. Since a chemical reaction equivalent to that of the upper end face of the core can be obtained and a gap is formed in the bottom, the aqueous solution can easily circulate in the reaction vessel, so that there is a remarkable effect that hydrogen can be stably obtained.

  In addition, the aqueous solution is drained after the hydrogen generation is completed, but the residual solution of the aqueous solution hardly adheres to the bottom end face of the reaction metal core due to floating by point contact, and is regarded as black dirt. Formation of a magnesium film can be prevented as much as possible, and cleaning is easy.
