1. pulsed flow of liquid device, it has a liquid entering hole part and a liquid outlet part, its in order to the fluid of the liquid entering hole part that will flow to this device continuously, low speed, controlled flow rate converts the interruption of the fluid that partly sprays from the liquid outlet of this device and the high flow rate of pulse to, comprising:

  • Fuse (9103) with liquid entering hole (9104) and liquid outlet (9105);

    A spring tube (9101), wherein;

    this spring tube (9101) wraps up and is contacting the major part of described fuse (9103) usually at least, and when fluid flowed through described fuse (9103), this spring tube (9101) left described fuse (9103) to form an expandable cavity (9125) between the surface, inside of the outer surface of described fuse (9103) and described spring tube (9101) inflatablely;

    It is characterized in that;

    Described cavity (9125) has a liquid entering hole part (9112) and a liquid outlet part (9115), the liquid entering hole (9104) of described liquid entering hole part (9112) and described fuse (9103) fluid by phased manner is communicated with, and the liquid outlet (9105) of described liquid outlet part (9115) and described fuse (9103) fluid by phased manner is communicated with;

    The described liquid entering hole (9104) of described fuse (9103) and the liquid entering hole of described cavity (9125) part (9112) fluid are communicated with, and the feasible fluid that flows to the described liquid entering hole (9104) of described fuse (9103) can reach the described liquid entering hole part (9112) of described cavity (9125);

    Under normal state, the shape of described spring tube (9101) can directly contact with described fuse (9103), thereby described liquid entering hole part (9112) that can directly closed described cavity (9125) and described liquid outlet be (9115) partly, and can prevent that fluid from flowing out from described cavity (9125);

    Hydrodynamic pressure in the described liquid entering hole part (9112) of described cavity (9125) surpasses first scheduled pressure value and reaches second scheduled pressure value, the effect of described spring tube (9101) fluid-responsive pressure is just partly expanded, thereby partly forms passage between (9115) in the liquid entering hole part (9112) of described cavity (9125) and the liquid outlet of described cavity (9125);

    When described spring tube (9101) when partly expanding, described spring tube (9101) wraps up and is contacting described fuse (9103) in the described liquid outlet part (9115) of described cavity (9125), thereby stop fluid to flow out to the liquid outlet (9105) of described fuse (9103) from the described liquid outlet part (9115) of described cavity (9125), thereby make hydrodynamic pressure increase in the described liquid entering hole part (9112) of described cavity (9125), cause the additional expansion of described spring tube (9101) and open the described liquid outlet part (9115) of described cavity (9125) more commodiously, the described liquid outlet part (9115) of quickening described cavity (9125) is communicated with the fluid of the described liquid outlet (9105) of described fuse (9103);

    Described pulsed flow of liquid device just penetrates fluid from described cavity (9125) with high flow rate by the described liquid outlet (9105) of described fuse (9103), make the volume and the pressure of the fluid that described cavity (9125) is interior reduce, the pressure that response descends, the described liquid outlet part (9115) of the closed described cavity of described spring tube (9101) (9125) is so just finish the discontinuous flow of fluid of the one-period of the described liquid outlet by described pulsed flow of liquid device.
