Description

Microbubble generator and microbubble water generator having the microbubble generator

The present invention relates to a bubble generating device, and more particularly to a microbubble generator.

In the past, the concept of purifying water quality was to use a water filter to purify water or use silver-containing substances to sterilize. Not only is the cost high, the filter material needs to be replaced frequently, and a large amount of waste water is generated to cause environmental pollution. The amount of water filtered by the water filter is small and cannot be applied to industries such as agriculture and fishery, and can usually only be applied to drinking water.

The currently known microbubble generators are classified into two types: gas-dissolved and liquid-powered. The gas-dissolved type is injected into the liquid by using high-pressure gas. The disadvantage is that a large amount of gas is consumed, and the cost is high, which is unfavorable for application in industry and home life. The liquid-power type is the type that is currently used more frequently. It uses the pumping water to recirculate and simultaneously draw in air, dissolves a large amount of high-density micro-bubbles in the circulating water, or uses vortex pumping to quickly convert the gas into small bubbles into the water. However, this type of microbubble generator usually has complicated equipment, high technical requirements, large power consumption, and large space required for installation, which is not conducive to home use and application of small and medium-sized agriculture and fishery industries. In addition, the micro-bubble generated by it The number of bubbles is often insufficient and the time that microbubbles stay in the water is too short to achieve the effect of purifying water and sterilizing.

Therefore, how to make the microbubble generator can effectively produce a large number of microbubbles, and the diameter of the microbubbles is small, and the cleaning effect of purifying water quality, sterilization, water saving efficiency, and low chemical detergent demand is widely applied to agricultural products, Industry, aquaculture, medical care, beauty and other industries have become the goals that the industry has striven to achieve.
