  FIG. 1 is a diagram showing the structure of a hydrogen-dissolved liquid discharge pot 100 that is an embodiment of the present invention.

  In FIG. 1, a hydrogen-dissolved liquid discharge pot 100 includes a pot body 1 and a hydrogen generator 2 attached to the pot body from the outside, and is manufactured in a fixed form. The hydrogen-dissolved liquid discharge pot 100 includes discharge means 3 having a discharge port 34 for discharging a liquid.

  The pot body 1 has a cylindrical shape on the outer surface and a bottle portion 11 in which the inside serves as a liquid storage tank. A liquid intended to dissolve hydrogen is stored in the bottle portion 11 and becomes a stored liquid. A liquid storage tank part is formed in the bottle part 11. The liquid is often drinking water such as mineral water (water) or tap water contained in a pot. The liquid may be coffee, tea or juice, may be a facial liquid, or may be a medicinal liquid. Hereinafter, the water accommodated in the pot will be described as a typical case of drinking water.

  The pot body 1 has a shape in which the upper part is narrowed.

  A lid 12 is provided on the upper portion of the pot body 1 having a narrowed shape. The lid 12 is attached to the pot body 1 by screwing by engagement by a screw groove mechanism 51 formed on the outer surface of the pot body 1 and the inner surface of the lid 12. A flat packing 52 is provided between the pot body 1 and the inner surface of the lid 12. The pot body 1 and the lid 12 are formed with substantially the same outer diameter.

  A hydrogen generator 2 is provided at the bottom of the pot body 1 so that it can be attached. The hydrogen generator 2 is attached to the pot body 1 by screwing by engagement by a thread groove mechanism 53 formed on the outer surface of the pot body 1 and the inner surface of the lid 12. The pot body 1 and the hydrogen generation part 2 are formed to have substantially the same outer diameter.

The hydrogen generation part 2 has an outer shape equivalent to that of the pot body 1 and a hydrogen generation space part 15 is formed therein. The hydrogen generation space 15 can store the hydrogen generating agent 17. A packing 54 is provided between the upper surface of the hydrogen generator 2 and the lower surface of the pot body 1. The hydrogen generation space 15 is connected to a hydrogen gas flow passage 16 formed on the pot body side. A check valve 18 is installed in the hydrogen gas flow passage 16. The hydrogen gas flow passage 16 is formed in the check valve holding body 20, and the check valve holding body 20 holds the check valve 18.

  The distal end portion of the hydrogen gas flow passage 16 is an inlet 19 having a small hole diameter, and the inlet 19 opens toward the bottle portion 11. As a result, the hydrogen generation space 15 is connected to the bottle 11 through the hydrogen gas flow passage 16, the check valve 18, and the inlet 19.

  The check valve 18 prevents water in the bottle part from leaking into the hydrogen generation space 15. When water is added to the hydrogen generating agent 17 disposed in the hydrogen generating space 15, hydrogen gas is generated and introduced into the bottle portion 11. A typical example of the hydrogen generating agent 17 is a mixed material made of an aluminum agent and calcium oxide, and the structure of the mixed material is well known. A hydrogen generating agent composed of a member other than a mixed material composed of an aluminum agent and calcium oxide may be used.

  In this example, the hydrogen generating part 2 is shaped to be attached to the lower part of the pot body 1. However, as is well known, for example, as shown in Patent Document 1, the hydrogen generating part is placed in the bottle part 11. You may make it install.

  The display line 22 is displayed and provided on the pot body 1 having a certain form so as to be visually confirmed. The display line 22 does not need to be provided all around the pot body 1. It is sufficient if the length is visible from the position direction. One round may be provided. A predetermined volume can be set in the pressure chamber 21 by indicating an assumed boundary between the pressure chamber that stores hydrogen in the bottle portion before hydrogen generation and the stored liquid in the bottle portion.

  A display line 22 indicating an assumed boundary between the pressure chamber 21 storing hydrogen and the stored liquid is provided on the surface of the pot body 1 in the horizontal direction. Therefore, the display line 22 has a function as a boundary line. In FIG. 1, one embodiment of the display line 22 is described. The display line 22 is displayed on the bottle part so as to be visually confirmed with a predetermined width. The display line 22 is printed and displayed on the upper surface or the inner surface of the bottle portion so as to be visually confirmed. It may be affixed. As a result, the position of the pressure chamber 21 partitioned from the stored liquid is instructed, a predetermined volume is set, and the visual angle is confirmed that the pressure chamber is formed, and the size of the volume is confirmed. It is important to be able to confirm the viewing angle when the user determines and stores the recommended amount easily when storing the drinking water in the pot body 1. The display line 22 may be formed by various displays such as a straight line, a linear arrangement of star marks, and a linear arrangement of symbol marks. As will be described later, the display line 22 is displayed in accordance with various needs by determining the arrangement position in advance by conducting some experiments in consideration of the discharge water amount, discharge strength, discharge time length, and the like. The

  As shown in FIG. 4, a plurality of display lines 22 may be provided up and down based on the reference line. This makes it possible to set a minus line that reduces the volume in the pressure chamber when it is desired to increase the discharge pressure when the line used for discharging the entire amount of liquid in the bottle is used as the reference line, and when it is not necessary to discharge the entire amount of liquid in the bottle. The positive pressure may be set by decreasing the discharge pressure to increase the volume in the pressure chamber. Which instruction line is suitable and recommended for use is explained in the explanatory text.

  The discharge means 3 is composed of a discharge pipe 31 and an on-off valve 32 provided in the middle of the discharge pipe 31, and a suction tip port 33 of the discharge tube 31 is disposed at the bottom in the bottle portion, and the tip port 33 is set where. This is important in relation to the discharge amount of the stored liquid in the bottle portion.

  The other end is a discharge port 34. The discharge pipe 31 can be formed of a tube. The suction tip port 33 may be disposed so as to reach the bottom surface. The discharge means 3 is simply formed so that all the liquid in the bottle part can be discharged. Here, “all discharge” means that all the liquid up to the discharge port 34 is naturally discharged.

  In the case of this example, the on-off valve 32 is provided with a push-type on-off valve. The on-off valve 32 constitutes an on-off body, and includes a valve portion 61 that is pressed by the valve seat, a push shaft 62 attached to the valve portion, a spring 63 that normally presses the push shaft 62 in the closing direction, and the push shaft 62 is closed. It consists of a push body 64 operated in the direction and a connecting pipe 65 to the discharge pipe 31. By pushing the push body 64 with a finger, the valve portion 61 is separated from the valve seat, and the hydrogen drinking water from the discharge pipe 31 flows to the other discharge pipe 31A. You may make it fix a push position, when pushing. In that case, it is returned to the original position by pushing again.

  The form as the on-off valve is not limited to this example. Any other form can be adopted as long as the discharge can be controlled.

  In this example, the ON / OFF type on-off valve 32 is used. However, the discharge pressure is continuously controlled by using a controllable on-off valve in which the degree of opening / closing can be appropriately set, and the discharge water having the same form pressure is used. Also good.

  Hydrogen drinking water is guided to the discharge port 34 from the other discharge pipe 31A. A spray head 35 is detachably provided at the discharge port 34. The discharge port 34 may be provided with various heads, or may be a head specific to an application corresponding to the application. When an athlete or general user drinks hydrogen drinking water, a drinking mouth head is attached. An O-ring 65 is provided between the push shaft 62 and the inner surface of the lid and between the valve seat 61 and the inner surface of the lid.

  While the open / close valve 32 that opens and closes the discharge pipe 31 is closed by the hydrogen generated in a predetermined amount of the hydrogen generating agent 17 installed in the hydrogen generating space 15, the pressure of the pressure chamber 21 that is divided in volume. In addition, when the discharge pressure is sufficient to discharge all the liquid in the bottle portion and the opening / closing valve 32 is opened or stopped intermittently, the discharge of the liquid in the bottle portion is continued. Is maintained at a pressure sufficient to continue the discharge of the hydrogen-dissolved liquid that reaches the temperature. If the on-off valve 32 that opens and closes the discharge pipe 31 is not provided, the generated pressure immediately disappears, and it is not possible to generate a discharge pressure sufficient to discharge all the liquid in the bottle part. Further, unless a sufficient discharge pressure is generated, the hydrogen-dissolved liquid cannot be continuously discharged.

  The inventors conducted an experiment to examine the relationship between the pressure chamber pressure (bottle internal pressure) (MPa) and the discharge water volume (ml).

  FIG. 2 is a diagram showing the relationship between the pressure (pressure chamber pressure) (MPa) formed in the pressure chamber and the discharge water amount (ml). The pressure chamber pressure is also the pressure in the pressure chamber 21, that is, the discharge pressure. FIG. 2A shows the acquired data, and FIG. 2B shows the acquired graph.

FIG. 3 is a diagram illustrating the relationship between the pressure chamber volume and the pressure chamber pressure. FIG. 3A shows the acquired data, and FIG. 3B shows the acquired graph.
(Experiment Content) The relationship between the bottle internal pressure and the discharge water amount when hydrogen water was generated in the hydrogen-dissolved liquid discharge pot shown in FIG. 1 was examined.
(Experimental equipment) Hydrogen-dissolved liquid discharge pot (Personal 2007 water generator manufactured by NTC Dreammax Co., Ltd.): Pot body volume (380 ml), liquid volume (300 ml), pressure chamber volume (80 ml), pressure chamber volume / Pot body capacity: 80ml / 380m ≒ 0.2 (20%)
Hydrogen generator: Mixed material consisting of aluminum and calcium oxide (hydrogen generator from NTC Dreammax Co., Ltd.)
Pressure gauge: Pressure gauge of the inventor modified from a commercially available pressure gauge Hydrogen water: Hydrogen-dissolved drinking water (hydrogen drinking water)
(experimental method)
1. Produces hydrogen drinking water in a hydrogen-dissolving liquid discharge pot.
2. At this time, the amount of hydrogen generating agent and reaction water was adjusted, and the pressure in the pressure chamber was changed.
3. Each pressure chamber pressure and discharge amount were measured and the relationship was examined.
(Experimental results) The experimental results are shown in FIG. 2 (a) and FIG. 2 (b). FIG. 2 (a) is data showing the amount of hydrogen generating agent (g), the amount of reaction water (ml), the measured pressure (MPa), the amount of discharged water (ml), and the discharge time for each Test-No. (B) is a graph which shows the relationship between a pressure (MPa) and discharge water amount (ml) based on the data shown by Fig.2 (a).
FIG. 3A shows data indicating the relationship between the pressure chamber volume (ml) and the pressure chamber pressure (Mpa) for each other Test-No, and FIG. 3B is a graph obtained from the data. Indicates.
(Discussion) From the experimental results, there was a correlation among the pressure chamber pressure, the pressure chamber volume, and the discharge water amount. Therefore, the discharge water amount is determined by determining the pressure chamber pressure and the pressure chamber volume. There is an unambiguous relationship with the amount of hydrogen generating agent, and defining the pressure in the pressure chamber indicates the amount of hydrogen generating agent used. Pressure chamber pressure and pressure chamber volume play an important role in discharging hydrogen drinking water in the bottle.

  As shown in FIG. 2A, all the liquid in the bottle is discharged at a pressure of 0.25 MPa. The pressure of 0.25 MPa is a pressure necessary to discharge all the liquid in the bottle part. As shown in FIG. 2 (b), a pressure of 0.26 MPa is employed with a margin to ensure ejection. The pressure of 0.26 MPa is a necessary and sufficient pressure to discharge all the liquid in the bottle part.

  Thus, in order to discharge hydrogen drinking water (300 ml) which is the liquid capacity in the bottle part, a pressure of 0.25 MPa or more is required. Therefore, in order to quickly discharge all the hydrogen drinking water (300 ml) in the bottle part, 50 ml can be discharged at 0.05 MPa, and therefore 0.26 MPa obtained by adding 0.01 MPa to 0.25 MPa is necessary and sufficient. If necessary, for example, it is 0.3 MPa according to the needs of the customer. Therefore, the necessary and sufficient pressure is a pressure that is necessary and sufficient by adding a slight pressure to the necessary pressure required for discharging the hydrogen-dissolved liquid reaching the bottom of the bottle portion. The slight pressure means 0.01 MPa added to the necessary pressure (for example, 0.25 MPa). Add 0.01 MPa or more. For example, 0.01 to 0.05 MPa is added. This eliminates the need to install more hydrogen generator than necessary. The pressure chamber volume is an important factor in maintaining these pressures. It is important to provide a display line 22 indicating the boundary between the pressure chamber 21 and the liquid level on the surface of the pot body. The setting of the display line 22 can be dealt with by determining the arrangement position in advance by conducting some experiments in consideration of the discharge water amount, the discharge strength, the length of the discharge time, etc., corresponding to various needs. . In consideration of the fact that the user stores the liquid in the hydrogen-dissolved liquid discharge pot, the display line 22 is preferably configured so that the user can easily confirm the visual angle. It only needs to be confirmed. When the volume of the pressure chamber 21 increases, the inclination (gradient) shown in FIG. 2A becomes slow, and when the volume of the pressure chamber 21 decreases, the inclination becomes steep, but the tendency does not change. In any case, the importance of providing the display line 22 does not change. When forming the pressure chamber pressure, an auxiliary agent such as a foaming agent may be used. The use of a foaming agent does not depart from the spirit of the present invention.

In view of this, the discharge amount and discharge time are determined by the pressure chamber pressure in a fixed form when a pot in a fixed form is used. 1. Amount of hydrogen generating agent The relationship is determined by the size of the pressure chamber volume.

  When the volume of the pressure chamber 21 and the pressure chamber pressure are determined, the hydrogen generation amount (that is, the hydrogen generating agent amount), the discharge amount, and the discharge time are uniquely determined. Therefore, the pressure chamber volume and the pressure chamber pressure are determined in order to determine the total discharge amount in the pot body. Further, when the pressure chamber volume and the pressure chamber pressure are determined, the discharge amount in the pot body is determined.

  In the present embodiment, as described above, the display line 22 is displayed on the pot body 1 in a certain form so as to be visually observable, and the pressure chamber for storing hydrogen in the bottle portion before hydrogen generation and the liquid stored in the bottle portion A predetermined volume is set in the pressure chamber 21. The user can easily set a predetermined volume in the pressure chamber 21 by the display line 22.

  By displaying the display line 22 indicating the assumed boundary between the pressure chamber 21 storing hydrogen and the stored liquid in the bottle portion, the pressure chamber 21 having a set volume is easily formed, and the entire amount of drinking water in the main body pot is supplied. The amount of the hydrogen generating agent 17 to be discharged can be used while being suppressed as much as possible.

  A discharge pressure is formed in the pressure chamber 21 while the opening / closing valve 32 that opens and closes the discharge pipe 31 is closed, which is determined by the volume determined by the position on the display line 22 and the amount of the hydrogen generating agent 17. When the on-off valve 32 is opened, the bottle-stored liquid is formed at a pressure sufficient to discharge all the liquid up to the suction tip port 33 of the discharge pipe 31 arranged at the bottom.

  In many cases, the hydrogen generating agent 17 is quantitatively put in a small bag, and one of the hydrogen generating agents 17 in a bag is used at the time of use. And in use, appropriate water is added. Controlling the amount of the hydrogen generating agent 17 corresponding to the application increases the cost for maintaining versatility. Compared to this, the setting of the display line 22 is easy, and the increase in cost can be kept to a minimum. Compared to controlling the amount of the hydrogen generating agent 17, there is an advantage of prioritizing the display line setting.

  The discharge pressure determined by the volume of the pressure chamber 21 determined by the position of the display line 22 and the amount of the hydrogen generating agent 17 to discharge all of the stored liquid in the bottle part to the suction front end of the discharge pipe arranged at the bottom is the hydrogen generating agent. When the amount of 17 is constant, the display line position is set so that a sufficient discharge pressure added by 0.01 MP or more is obtained.

  A spray injection nozzle is connected to the discharge pipe discharge port, and the pressure chamber 21 is sufficient to discharge the spray liquid by setting the position of the display line 22 when the amount of the hydrogen generating agent 17 is constant. The discharge pressure is maintained. A spray injection nozzle may be fixed to the discharge port 34 in advance.

  A drinking port is connected to the discharge port 34 of the discharge pipe 31, and the pressure chamber 21 discharges drinking water from the drinking port by setting the position of the display line 22 when the amount of the hydrogen generating agent 17 is constant. The discharge pressure is maintained at a sufficient level. A drinking port may be fixed to the discharge port 34 in advance. You may make it select a spray nozzle and a drinking mouth suitably.

  Necessary to discharge all the liquid in the bottle part while the pressure chamber 21 takes in the hydrogen generated in the hydrogen generation space part 15 installed outside the bottle part and the on-off valve 32 for opening and closing the discharge pipe 31 is closed. When the opening / closing valve 32 is intermittently or continuously opened, the discharge of the liquid in the bottle is continued and the discharge of the hydrogen-dissolved liquid reaching the bottom of the bottle is continued. Can be maintained at a necessary and sufficient pressure. Accordingly, the user can form a discharge pressure that can meet various needs by using the hydrogen-dissolved liquid discharge pot, and can easily set and visually check the discharge pressure. By continuously discharging or spraying the liquid for a certain period of time under the necessary and sufficient discharge pressure, all the liquid in the bottle part in which the hydrogen-dissolved liquid discharge pot is stored can be discharged and used.
