Detailed Description
In order to make the present invention more popular and easy to understand, the present invention will be further explained below with reference to the embodiments and the accompanying drawings.
The utility model provides a dripper (for short, refer to fig. 1-4) capable of eliminating satellite droplets, which comprises a dripper body 3 connected with an external drip plate, wherein two inclined runners and a vertical runner are arranged in the dripper body 3, the two inclined runners are converged together at the tail end and connected with the vertical runner, the three jointly form a Y-shaped runner 4 for liquid to pass through, and the two inclined runners penetrate through the top of the dripper body 3 and form two liquid inlets 1 at the top of the dripper body; the upper end of the drainage device is fixedly connected to the dripper body at the junction tail end of the two inclined flow channels, the drainage device is coaxially arranged in the vertical flow channel of the dripper body 3, the tail end of the drainage device 2 is provided with a tip part 5, and the tip part 5 extends out of one section of distance from the tail end of the vertical flow channel of the Y-shaped flow channel 4.
The inclined flow channel forms an included angle of 30 degrees or 45 degrees with the vertical direction; the design can satisfy drainage device and keep at the center of runner like this, can guarantee that the liquid drop inflow resistance is less when not hindering drainage device's setting moreover.
The drainage device 2 is a slender cylinder, the tail end of the drainage device is provided with a tip, and the height of the tip is the same as the diameter of the cylindrical part of the drainage device; the liquid will form very thin liquid bridge at the end of drainage device 2, under the unstable effect of rayleigh, fracture very fast, the liquid after the fracture contracts under surface tension and balling, the part that does not fracture will contract under the viscous force to the tip 5 of drainage device 2 and join with new liquid, continue the fracture, so reciprocal, will reduce the formation of satellite liquid drop like this.
