Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic hydrogen production, and more specifically to a pressure relief cup cover and a hydrogen water cup. Background Art

[0002] The hydrogen production cup electrolyzes the water in the cup to produce hydrogen through the electrolysis module set at the bottom of the cup, and the cup has a certain pressure bearing performance (such as 0.3MPa-0.6MPa), so that the hydrogen in the cup is more easily dissolved in the water under pressure to form hydrogen-rich water. Existing hydrogen production cups usually have the function of active pressure relief. When the electrolysis module electrolyzes the water in the cup to form a certain pressure (such as 0.3MPa-0.6MPa) in the cup, the pressure pushes the pressure-bearing component upward, so that a gas channel is formed in the cup cover, thereby releasing hydrogen to the outside.

[0003] However, when the user continuously triggers the electrolysis module to work, the pressure value in the cup body may remain at the peak value for a long time, and the pressure-bearing component is also in a pushed-up state, so that the hydrogen cannot be well utilized. Utility Model Content

[0044] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0045] like Figure 1-Figure 2 As shown, in the first embodiment of the hydrogen water cup of the utility model, the hydrogen water cup 10 includes an electrolytic component 100, a cup body 200 and a pressure relief cup cover 300;

[0046] The electrolysis assembly 100 is disposed at the lower end of the cup body 200 and is detachably connected to the cup body 200, and is used to electrolyze the water in the cup body 200 to generate hydrogen;

[0047] The lower end of the pressure relief cup cover 300 and the upper end opening of the cup body 200 are detachably arranged to seal the cup body 200 so that the cup body 200 can withstand pressure, thereby increasing the concentration of hydrogen dissolved in water;

[0048] The detachable part can be fixed by threaded connection or clamping.

[0049] exist Figure 3-Figure 4 In the first embodiment of the pressure relief cup cover of the utility model, the pressure relief cup cover 300 includes an outer cover 301, a cover pressure assembly 302, a sealing assembly 303 and a pressure bearing assembly (304-309);

[0050] The outer cover 301 is a cylindrical body with a hollow interior and two ends are open structures (not shown) for installing the cover pressing assembly 302 and placing the sealing assembly 303;

[0051] The cover pressing assembly 302 is configured as a circular structure, one end 302a of which is inserted into one side of the upper opening of the outer cover 301, and the other end of the cover pressing assembly 302 covers the upper opening of the outer cover 301;

[0052] The sealing component 303 is a cylindrical structure, which is arranged in the outer cover 301, and has an internal thread on its inner wall, which is engaged with the external thread of the bottle mouth of the cup body 200 through the internal thread to seal the cup body 200;

[0053] The pressure-bearing components (304-309) are arranged in the cavity 303c of the sealing component 303 and are arranged in close contact with the through hole 303a;

[0054] For example, assuming that the peak pressure of the pressure-bearing component (304-309) is 0.65Mpa, when the electrolysis component 100 continues to electrolyze the water in the cup body 200, a certain air pressure is formed in the cup body 200. When the air pressure in the cup body 200 is greater than the peak pressure of 0.65Mpa, the pressure-bearing component (304-309) is pushed upward by the air pressure in the cup body 200, so that the pressure-bearing component (304-309) is separated from the through hole 303a, and hydrogen is output through the through hole 303a and the pressure-bearing component (304-309);

[0055] Specifically, the sealing assembly 303 covers the upper opening extension of the cup body 200 and is detachable from the cup body 200.

[0056] An axial through hole 303a is provided in the sealing assembly 303, so that the sealing assembly 303 can communicate with the cup body 200;

[0057] Furthermore, the lower end surface of the pressure-bearing component (304-309) is in contact with the upper end surface of the sealing component 303 and is in contact with the upper end of the through hole 303a to seal the through hole 303a;

[0058] A hydrogen outlet 320a is provided at the upper end of the pressure-bearing component (304-309). When the pressure-bearing component (304-309) is pushed upward by the gas pressure in the cup body 200 so as to separate from the through hole 303a, the hydrogen in the cup body 200 is output through the through hole 303a and the hydrogen outlet 320a.

[0059] Furthermore, the cover pressing assembly 302 and the pressure bearing assembly (304-309) are detachably connected, and the lower end surface of the cover pressing assembly 302 abuts against the hydrogen outlet 320a;

[0060] The covering pressure component 302 is separated from the pressure-bearing component (304-309). When the pressure-bearing component (304-309) is pushed upward by the internal air pressure of the cup body 200, the pressure-bearing component (304-309) is separated from the through hole 303a, and the hydrogen flows through 303a and the air flow channel 320 to the hydrogen outlet 320a for use by the user.

[0061] By using the technical solution, when the internal air pressure of the cup body 200 is greater than the pressure value of the pressure-bearing component (304-309), the pressure-bearing component (304-309) is pushed upward by the air pressure, and an airflow is formed in the pressure-bearing component (304-309). Hydrogen is output through the airflow channel 320 for use by the user. This can effectively solve the problem that the pressure value in the cup body 200 may remain at a peak value for a long time, while the pressure-bearing component is also in a pushed-up state, and hydrogen is continuously released outward, resulting in hydrogen waste.
