Microbubble device

This creation is related to the foaming device, and in particular to a microbubble device.

In general, a foaming device can make the water flow more delicate and contain foam, as disclosed in TWM 424,358.

However, such conventional foaming devices are used for mixing air and water directly in the foaming device, without any mechanism for sufficiently mixing air and water, and refining air bubbles, and the air and water are not uniformly mixed. Moreover, the bubbles in the water are large and the size is different, so that the water flow cannot continue to maintain a dense and foamy state, and there is a defect that needs to be improved.

Therefore, it is necessary to provide a novel and progressive microbubble device to solve the above problems.

The main purpose of this creation is to provide a microbubble device that provides a very fine and dense foam water flow.
