Abstract
The utility model provides a spray nozzle. The spry nozzle comprises an inflow channel, a vortex cavity and an outflow channel, wherein, the inflow channel is communicated with the vortex cavity along the tangential direction; the outflow channel is communicated with the vortex cavity along the axial direction of the vortex cavity; and the throughflow section of the inflow channel gradually decreases. As the throughflow section of one part of the inflow channel along the direction of the vortex cavity is larger than that of the other part of the inflow channel, namely, the throughflow section of the inflow channel is inconsistent, and the throughflow section of one part of the inflow channel near to the vortex cavity is smaller than that of the other part of the inflow channel far from the vortex cavity, the flow velocity of liquid flowing through one part of the inflow channel is higher than that of the liquid flowing through the other part of the inflow channel under the same flow rate, thereby the flow velocity of the liquid flowing into the vortex cavity is increased.

The specific embodiment
Below with reference to accompanying drawing the specific embodiment of the present utility model is described in detail.
As shown in Figure 3 and Figure 4, nozzle provided by the utility model includes circulation road 5, swirl chamber 6 and goes out circulation road 7, goes into circulation road 5 and tangentially is communicated with swirl chamber 6, goes out circulation road 7 axially being communicated with swirl chamber 6 along swirl chamber 6, wherein, the passage section of going into circulation road 5 reduces.
In going into circulation road 5, because the passage section of going into circulation road 5 reduces, thereby when liquid was flowed through the less part of passage section, flow velocity was improved naturally.
According to a kind of embodiment of the present utility model, go into circulation road 5 and comprise first port 8 and be positioned at into the passage section of circulation road 5 and second port, 9, the second ports 9 of swirl chamber 6 intersections passage section less than first port 8.Like this, the speed of the speed when liquid is flowed through second port 9 when flowing through first port 8 enters the flow velocity of swirl chamber 6 thereby improved liquid.
The variation of going into the passage section of circulation road 5 can be achieved by various ways, according to a kind of embodiment of the present utility model, as Fig. 4 and shown in Figure 7, go into circulation road 5 and between first port 8 and second port 9, also comprise the passage section of the passage section of first cylindrical channel 10, frustum of a cone passage 11, second cylindrical channel 12 and third channel 14, the first cylindrical channels 10 that are communicated with successively greater than second cylindrical channel 12.Like this, by frustum of a cone passage 11, liquid has been realized the raising of flow velocity when the flow velocity of second cylindrical channel 12 of the flowing through flow velocity when flowing through first cylindrical channel 10.
The passage section of second cylindrical channel 12 can equate with the passage section of third channel 14, and in this case, the flow velocity of liquid in second cylindrical channel 12 equates with flow velocity in the third channel 14.
In the preferred case, the passage section of third channel 14 is less than the passage section of second cylindrical channel 12, and third channel 14 is that the cylindrical passageway 15 and the cross sectional shape of rectangle is that semicircular semi-circular channel 16 forms by cross sectional shape, and a side 17 of cylindrical passageway is tangent with the circumference side of swirl chamber 6.
