technical field

The utility model relates to the technical field of generation of micro-nano bubbles, in particular to a shower system formed by means of pressurized dissolved gas to separate out micro-nano bubbles, and is especially suitable for bathing and health care of the human body.

Background technique

After 20 to 30 years of development in China, Jacuzzi and steam rooms have become more and more mature due to the increasingly mature technology, easy matching, small investment, more and more small manufacturers, and increasingly fierce competition. In addition, the overall market demand is declining. Under this market competition situation, to continue to achieve sales growth, it is an inevitable choice to take the route of product innovation and differentiation. The application of micro-nano bubble technology in sanitary products will be able to meet people's health care needs, improve product quality, Increase the added value of products and promote product sales.

Micro-nano bubbles refer to bubbles with a diameter of micro-nano level, which have different physical and chemical properties from ordinary bubbles. The size of micro-nano bubbles is very small, so its surface tension is much lower than that of ordinary bubbles. The decrease in surface tension makes it easier for O ₂ molecules to combine with water molecules, so that the bubbles become heavier than the surrounding area, and the settlement of the bubbles is realized; At the same time, oxygen molecules break the interface of water, making it easier to dissolve into water. At the same time, due to the small diameter of the micro-nano bubbles, they can easily penetrate into the pores and take away the dirt in the pores; at the same time, a large number of bubbles dissolve and rupture in the water, and the instantaneous maximum temperature is about 5,500 degrees Celsius, and when they rupture, it produces about 400 kilometers per hour. Ultrasound, and a large number of negative oxygen ions occur. This sparkling water can sterilize, enhance human immunity, purify blood, and improve allergic constitution; beauty care, skin cleansing, exfoliation, whitening effect, moisturizing skin, increasing elasticity; improving skin diseases, improving skin allergies, improving Acne, improve athlete's foot, improve eczema; and have the effect of increasing physical strength, recovering fatigue, improving sleep, etc.
