A hydrogen-rich water cup

Abstract

The invention relates to a hydrogen-rich water cup which comprises a cup lid, a cup body and a base. The cup lid comprises a cup lid shell, a stop piece, an O-shaped sealing ring and a one-way pressure release valve; the one-way pressure release valve comprises an inner piece, a connecting rod, a sealing face and a connecting rod reset device, the stop piece is arranged on the inner side face of the cup lid shell, the connecting rod sequentially penetrates through the cup lid shell and the stop piece, one end of the connecting rod is fixedly connected with the inner piece, and the other end of the connecting rod is fixedly connected with the sealing face; the sealing face is contained in a concave portion of the outer surface of the cup lid shell, and the stop piece is provided with a groove for fixing the O-shaped sealing ring which is arranged on the connecting rod in a sleeving mode.

Description

technical field [0001] The invention relates to a water cup cover, in particular to a hydrogen-rich water cup. Background technique [0002] At present, the hydrogen-rich water cups on the market only have the function of electrolysis, without the function of dechlorination. If electrolysis is added to tap water, it will contain residual chlorine. Drinking it for a long time will cause certain harm to the human body; and for pure water, since there is no electrolyte in pure water, it cannot Hydrogen is obtained by electrolysis. [0003] Moreover, at a certain concentration, the hydrogen produced by the hydrogen-rich water cups currently on the market will generate sparks in the electrolytic sheet separated by the ion membrane, and then cause an explosion. For safety, a pressure relief valve is usually used for pressure relief.

[0002] At present, the hydrogen-rich water cups on the market only have the function of electrolysis, without the function of dechlorination. If electrolysis is added to tap water, it will contain residual chlorine. Drinking it for a long time will cause certain harm to the human body; and for pure water, since there is no electrolyte in pure water, it cannot electrolysis to hydrogen

[0003] Moreover, at a certain concentration, the hydrogen produced by the hydrogen-rich water cups currently on the market will generate sparks in the electrolytic sheet separated by the ion membrane, and then cause an explosion. For safety, a pressure relief valve is usually used for pressure relief. Existing The structure of the pressure relief valve in the technology usually adopts the structure that the O-ring seals the gap between the cup cover shell and the connecting rod, see figure 1 , the hydrogen-rich water cup cover includes a cover shell 1, an inner piece 2, a first spring 3, a retainer 4, an O-ring 5 and a link 6, wherein the retainer and the link adopt a top seal structure, which is reliable Poor performance, when the connecting rod is slightly tilted or the O-ring is displaced when the pressure relief valve is displaced, it will cause water leakage; at the same time, the structure of the pressure relief valve on the lid of the hydrogen-rich water cup on the market is one-way pressure relief, which generates hydrogen during the electrolysis process And oxygen, so that the internal pressure of the cup increases, but the pressure relief requirements cannot be met, at this time, the lid of the cup is difficult to unscrew due to the increased pressure inside the cup
