the dripper body assembly 1 comprises a dripper body 11, a body step 12 and an outer column 15, wherein the body step 12 is arranged inside the dripper body 11, an inner water outlet 13 is formed in the center of the top of the body step 12, an auxiliary flow passage 14 is formed in one side of the inner water outlet 13, the outer column 15 is located at the center of the dripper body 11, a water outlet 16 is formed in the center of the top, and the water outlet 16 is communicated with the inner water outlet 13.
The dripper base assembly 3 comprises a dripper base 31 and a barbed water inlet pipe 33, and the bottom of the dripper base 31 is fixedly connected with the barbed water inlet pipe 33.
In this embodiment, the connection can be dismantled through the screw thread to dripper body 11 and dripper base 31, can dismantle the washing after conveniently blockking up, adopts the pressure compensation chip 2 of two kinds of different grade types simultaneously, is applicable to the situation of different flow, makes to irrigate more evenly, and the use of runner is also more added has the branch nature, so has reduced the possibility of blockking up.
Further, the pressure compensation chip 2 is placed in the body step 12, and a central through hole 21 is formed in the pressure compensation chip 2.
In the embodiment, when the pressurized water is in a small flow, one pressure compensation chip 2 without a through hole is adopted, and when different water pressures pass through the pressure compensation chip 2, the cross-sectional area of the water can be controlled to perform pressure compensation due to the elastic deformation and the action of the secondary flow channel 14, so that the flow is not changed under certain pressure change; when pressurized water is high in flow, the pressure compensation chip 2 with the central through hole 21 is adopted, the size of the central through hole 21 can be changed through the water pressure impact chip, the water passing sectional area is controlled, and therefore the flow is constant under certain pressure change.
Further, the outer surface of the dripper body 11 is provided with external vertical ribs 111, and the external vertical ribs 111 are distributed annularly, uniformly and at intervals.
In the present embodiment, the strength of the product is enhanced and the feeling of the hand is increased when the body is twisted by the hand.
Further, an internal thread 112 is arranged inside the dripper body 11, an external thread 32 is arranged on the outer surface of the dripper base 31, and the internal thread 112 and the external thread 32 are matched with each other.
In the present embodiment, the two are adapted to each other so that the dripper body 11 and the dripper base 2 are detachably connected by a screw thread.
Further, a water inlet 17 and an efficiency labyrinth flow passage 18 are also formed in the step 12 of the body.
In the present embodiment, the performance labyrinth flow passage 18 is a rectangular sawtooth structure, and is distributed in a single circle, and the inner and outer sides of the sawtooth are staggered to form a curved path for passing pressurized water, so as to extend the water flow path and consume the pressure of irrigation water by continuously impacting the rectangular sawtooth, thereby achieving the effect of pressure reduction.

In the present embodiment, the diameter of the seal groove 34 is slightly smaller than that of the main body step 12, so that the seal groove and the main body step are fixed to each other and do not fall off, thereby performing a certain sealing function.
The utility model discloses a theory of operation and use flow: after the utility model is installed, when the pressurized water is in a small flow specification, the pressure compensation chip 2 without a through hole in the center is adopted; pressurized water enters the interior of the dripper from the barbed water inlet 33, and because of the obstruction of the membrane of the pressure compensating chip 2, pressurized water can only enter the performance labyrinth flow passage 18 from the water inlet 17 and pass through all labyrinth flow passages of the performance labyrinth flow passage 18. When the water pressure is low, the water flow impacts the pressure compensation chip 2 before entering the water inlet 17 to deform, but a gap H is also reserved between the pressure compensation chip 2 and the water outlet platform, and the water flow flows to the inner water outlet 13 from the gap after passing through the efficiency labyrinth runner 18 and flows out from the water outlet 16; when water is high pressure, the clearance H is 0 after the water flow impacts and deforms the pressure compensation chip 2, the water flow only enters the auxiliary flow channel 14 after passing through the efficiency labyrinth flow channel 18, then enters the inner water outlet 13, and then flows out of the water outlet 16;
when the pressurized water is in a large-flow specification, the pressure compensation chip 2 with the through hole in the center is adopted, the pressurized water enters the lower head from the barb water inlet 33, the water flow is blocked by the diaphragm, but because the chip is provided with the central through hole 21, the water flow directly enters the inner water outlet 13 from 21 and flows out from the water outlet 16, when the large-flow specification is adopted, the efficiency labyrinth flow channel 18 and the auxiliary flow channel 14 do not work, at the moment, when the water is in a low pressure, the water flow enters the central through hole 21 again, the middle of the pressure compensation chip 2 is impacted to deform, the central through hole 21 becomes D2 due to the deformation of the chip, the water enters the inner water outlet 13 through D2 and then flows out through the water outlet 16, and at the moment; when water is at high pressure, the central through hole 21 is smaller as D1 due to impact deformation, water flows into the inner water outlet 13 through the D2 and then flows out through the water outlet 16, and at the moment, the pressure is high and the flow speed is high.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
