A kind of foam bathtub
Technical field
The present invention relates to the technical field of bathtub, particularly relate to a kind of foam bathtub.
Background technology
Conventional bubble bath, is mixed with air under the impact of current by the bubble bath containing chemical compositions such as surfactant, albumen, glycerol and is formed often.The bathing experiences of this bubble is not good: it is short 1) to hold the bubble time, because the mode of this generation foam is only utilize water impact to produce, so foam is big, it is easy to broken;2) experiencing bad, because foam beads size is not enough, it is short to hold the bubble time, so have more than is needed, how long foam is with regard to Lock-out, it is impossible to persistently cover on the person;3) consumption is big, in order to utilize water impact to produce foam, it has to adopt bigger bath COnCentratlon, thus causing waste.
Summary of the invention
Even if the technical problem to be solved in the present invention is to provide, a kind of foaming effect is good, the careful foam that also can continuously generate high-quality under only small pressure of foam, and the foam bathtub being not easily blocked.
