Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0030] The hydrogen water cup includes an electrolysis module, which can electrolyze water to generate hydrogen and then mix the hydrogen with water to prepare hydrogen-rich water. It has the advantages of being small in size and suitable for home use. However, the existing hydrogen water cup has certain defects. When producing hydrogen water, drinking water directly contacts the electrode, which is a metal structure. Long-term use may cause heavy metal contamination of drinking water. In addition, the water in the hydrogen water cup must be pure water or distilled water, which cannot meet the needs of users who need to use other types of beverages.
[0031] like Figure 1 As shown, this embodiment provides a hydrogen water cup electrode isolation chamber, comprising:
[0032] The isolation chamber body 1 includes a first connector 111 and a second connector 121, wherein the first connector 111 is used to connect to the water cup 5, and the second connector 121 is used to connect to the electrolysis module 4;
[0033] The one-way valve 2 is installed in the first connector 111 , and its opening direction is from the isolation chamber body 1 to the water cup 5 .
[0034] Among them, the first connecting head 111 and the second connecting head 121 are respectively arranged according to the connectors of the water cup 5 and the electrolysis module 4. It is required that after the connection, the isolation chamber body 1 can be connected to the water cup 5 and the electrolysis module 4 respectively through the first connecting head 111 and the second connecting head 121, and there will be no water leakage or air leakage.
[0035] Specifically, when in use, first fill the isolation chamber body 1 with pure water, then install the electrolysis module 4 on the second connector 121 of the isolation chamber body 1, and use the water in the isolation chamber body 1 as water for electrolysis; then connect the first connector 111 of the isolation chamber body 1 to the water cup 5 containing beverages; after the electrolysis module 4 is powered on, hydrogen will be produced in the isolation chamber body 1, and when the air pressure is large enough, the one-way valve 2 will be pushed open, and the hydrogen in the isolation chamber body 1 will enter the water cup 5 through the one-way valve 2, so as to achieve the purpose of preparing hydrogen-containing beverages. It should be noted that, generally, during the electrolysis process, the water cup 5 is located above the isolation chamber body 1, so that the prepared hydrogen can float up and gather near the one-way valve 2. After the one-way valve 2 is pushed open, since the internal pressure of the isolation chamber body 1 is much greater than the pressure in the water cup 5, the hydrogen will be discharged upward through the one-way valve 2, and the water in the water cup 5 will not leak into the isolation chamber body 1.
[0036] Based on the hydrogen water cup electrode isolation chamber of the present embodiment, an independent electrolysis space is provided for the electrolysis module 4, and the gas generated by electrolysis can be passed into the water cup 5 through the one-way valve 2 provided in the first connector 111 to prepare drinking hydrogen water, which can avoid the problem of heavy metal pollution caused by drinking water contacting the electrode. At the same time, the present solution for preparing hydrogen water has no requirements on the type of beverage in the water cup 5. Before electrolysis, only pure water needs to be loaded into the isolation chamber body alone, and any beverage can be added to the water cup 5. The hydrogen generated after electrolysis is passed into the water cup 5 alone and mixed with the beverage, thereby satisfying the user's need to freely choose the type of beverage.

The present solution provides a first connector 111 with an internal thread groove 11111, which can be directly adapted and connected with the traditional water cup 5 or water bottle, and has the advantages of good reliability and strong sealing after connection. Therefore, the present solution has the advantage of good adaptability. An inner mounting ring 1112 is provided in the outer connecting ring 1111, and the inner mounting ring 1112 can provide support for the installation of the one-way valve 2, so that the medium flow between the water cup 5 and the isolation chamber body 1 must be controlled by the one-way valve 2.
[0039] In one embodiment, a gas guide module 3 is further included. The gas guide module 3 is installed outside the first connector 111 and is used to split the hydrogen discharged from the first connector 111 .
