Problems solved by technology

[0004] 1. The electrolyzed water electrodes in the hydrogen-rich cup mostly adopt superimposed sheet structures. This type of structure has a small contact area with the water body and occupies a large space. It is not suitable for free combination of multi-electrode structures. The efficiency of electrolyzed water is low, and the prepared hydrogen Hydrogen concentration in water is not high
[0005] 2. The hydrogen bubbles generated by the existing electrolytic water electrodes are mostly micron-sized, and the solubility of micron-sized hydrogen bubbles in water is not high, and they cannot exist stably
[0006] 3. In addition, because the existing sheet-shaped electrolytic water electrodes are not suitable for the free combination of multi-electrode structures, they are only suitable for use in small devices such as hydrogen-rich cups, and cannot meet the needs of large amounts of hydrogen-rich water in daily life, industry, agriculture, etc.

Description

technical field [0001] The invention belongs to the technical field of electrolyzed water, and in particular relates to a tubular electrode for electrolyzed water, and an electrolyzed water device and application thereof. Background technique [0002] Hydrogen is the smallest and simplest molecule in nature and plays a very important role in life. Hydrogen can neutralize some highly oxidative reactive oxygen species in the body. When aqueous solutions rich in micron or nanometer hydrogen bubbles enter daily life, a large number of studies have shown that hydrogen-rich water can regulate the activity of oxidative metabolism, and has anti-fatigue and anti-cancer properties. , anti-inflammatory and other physiological effects. Therefore, hydrogen-rich water can not only be used as a new type of drinking water resource, but also an ideal antioxidant, and can even provide effective help in the prevention and treatment of chronic diseases. [0003] Therefore, the application of ...
