The bubbler uses the principle of water pressure and flow rate to make a large amount of fine foam formed by the water flow through the water valve, thereby making up for the disadvantage that the water flow is reduced due to the reduction of water volume. While saving water, the foam-rich water stream not only makes cleaning more thorough, but also reduces the scouring power of human skin, thus effectively protecting the skin. At the same time, the delicate water flow of the foam can effectively avoid the splashing of water, keep the flow table dry for a long time, and prevent the generation of harmful substance hotbeds.

Enhance water pressure - Prevent the water from splashing, the air and water flow are well mixed, the water flow is soft and enhanced, and the cleaning is more labor-saving and convenient. 360 degree universal rotation - The water flow can easily cover the entire sink, and it is more convenient to clean the sink.
