Hydrogen-enriched water cup lid

Abstract

The invention relates to a hydrogen-enriched water cup lid which comprises a cup lid shell, a stop piece, an O-shaped sealing ring and a one-way pressure relief valve. The one-way pressure relief valve comprises an inner piece, a linkage rod, a sealing face and a linkage rod reset device. The stop piece is arranged on the inner side face of the cup lid shell. The linkage rod sequentially penetrates through the cup lid shell and the stop piece. One end of the linkage rod is fixedly connected with the inner piece, and the other end of the linkage rod is fixedly connected with the sealing face. The sealing face is contained inside a concave portion of the outer surface of the cup lid shell. A groove for fixing the O-shaped sealing ring is arranged on the stop piece. The linkage rod is sleeved with the O-shaped sealing ring.

Description

technical field [0001] The invention relates to a water cup lid, in particular to a hydrogen-rich water cup lid. Background technique [0002] At present, the hydrogen produced by the hydrogen-rich water cups on the market will generate sparks in the electrolytic sheet separated by the ionic membrane at a certain concentration, and then cause an explosion. For safety, a pressure relief valve is usually used for pressure relief. In the prior art The structure of the pressure relief valve usually adopts the structure that the O-ring seals the gap between the cup cover shell and the connecting rod, see figure 1 The lid of the hydrogen-rich water cup includes a lid shell 1, an inner piece 2, a first spring 3, a baffle 4, an O-ring 5 and a connecting rod 6, wherein the baffle 4 and the connecting rod 6 adopt a top seal structure, the The structural reliability is poor.

[0002] At present, the hydrogen produced by the hydrogen-rich water cups on the market will generate sparks in the electrolytic sheet separated by the ionic membrane at a certain concentration, and then cause an explosion. For safety, a pressure relief valve is usually used for pressure relief. In the prior art The structure of the pressure relief valve usually adopts the structure that the O-ring seals the gap between the cup cover shell and the connecting rod, see figure 1 The lid of the hydrogen-rich water cup includes a lid shell 1, an inner piece 2, a first spring 3, a baffle 4, an O-ring 5 and a connecting rod 6, wherein the baffle 4 and the connecting rod 6 adopt a top seal structure, the The structural reliability is poor. When the connecting rod is slightly inclined 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 of the hydrogen-rich water cup cover on the market is one-way pressure relief. During the electrolysis process Hydrogen and oxygen are generated to increase the internal pressure of the cup, but the pressure relief requirement cannot be met. At this time, the lid of the cup is difficult to unscrew due to the increased pressure inside the cup.
