1. a kind of coaxial microfluidic control shower nozzle of level Four it is characterised in that:

  • Including a total capillary, the first tortuous capillary andTwo tortuous capillaries and the 3rd tortuous capillary;

    The external diameter of the first described tortuous capillary is less than the interior of described total capillaryFootpath;

    The external diameter of the second described tortuous capillary is less than the internal diameter of the first described tortuous capillary;

    The 3rd described curved hairsThe external diameter of tubule is less than the internal diameter of the second tortuous capillary;

    The straightway of the first described tortuous capillary is arranged on described totalIn capillary, the bend of the first described tortuous capillary passes from the side wall of the entrance point of described total capillary, instituteThe other end of the first tortuous capillary stated passes the port of export of described total capillary;

    The second described tortuous capillaryStraightway is arranged in the first described tortuous capillary, and the port of export of the second described tortuous capillary bends capillary from firstPass in the port of export of pipe, the other end of the second described tortuous capillary passes the first described tortuous capillary;

    DescribedThe bend of the second tortuous capillary pass from the side wall of the entrance point of described total capillary;

    The 3rd described curved hairsThe straightway of tubule is arranged in the second described tortuous capillary, and the port of export of the 3rd described tortuous capillary is curved from secondPass in the port of export of bent capillary, the other end of the 3rd described tortuous capillary passes the second described bending capillaryPipe;

    The bend of the 3rd described tortuous capillary passes from the side wall of the entrance point of described total capillary;

    DescribedIt is provided with ring on the lateral wall of bend entrance point of one tortuous capillary, the second tortuous capillary and the 3rd tortuous capillaryShape is raised;

    Described total capillary and the first tortuous capillary, the second tortuous capillary, the 3rd tortuous capillary straightway withAxle is arranged.
