[0015] The embedded dripper and drip irrigation device provided by this utility model have at least the following beneficial effects:

[0016] The embedded dripper includes a dripper body and an elastic pressure equalizing element. The dripper body is embedded in the inner wall of the drip irrigation pipe, and the elastic element is located inside the dripper body. Through its own elasticity, it plays a role in stabilizing pressure.

[0017] The dripper body has a water inlet chamber, and the elastic pressure equalizing element is disposed within the water inlet chamber.

The water inlet body has an inlet connected to the drip irrigation pipe. The continuous cavity has a connecting port, and the connecting port has a turbulent flow channel. The turbulent flow channel is connected to an outlet. During drip irrigation, water from the drip irrigation pipe enters the water inlet chamber through the inlet, and then sequentially passes through the continuous cavity, the connecting port, and the continuous cavity. The turbulent flow channel discharges water from the outlet. During the above process, when the water pressure is too high, the elastic pressure equalizing element will resist the water flow, thereby reducing the pressure. The pressure equalization effect is significant. Furthermore, when the elastic pressure equalizing element recovers its deformation, it has a backwashing effect, which can improve the anti-clogging effect. The turbulent flow channel has the effect of disturbing and turbulent flow, which further improves the pressure stabilization effect. With multiple connecting ports and turbulent flow channels, even if one flow channel is blocked, the other flow channels still have the function of guiding the flow, which has a significant anti-clogging effect and ensures the drip irrigation effect.

[0018] This invention incorporates an elastic pressure equalizing component, which increases resistance and reduces water pressure when it is too high, and also has an anti-blocking effect. By setting multiple connecting ports and turbulent flow channels, even if one channel is blocked, the water flow effect is not affected, resulting in a significant drip irrigation effect.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1:

[0035] This utility model provides an embedded drip irrigation nozzle, referenced Figures 1 to 7 As shown, the embedded drip irrigation nozzle includes a drip head body 11 and an elastic pressure equalizing component 12.

[0036] The dripper body 11 is embedded in the inner wall of the drip irrigation pipe 2. The elastic pressure equalizing element 12 is disposed in the dripper body. The dripper body 11 is provided with a water inlet cavity. The elastic pressure equalizing element 12 is disposed in the water inlet cavity. A water inlet cavity 14 and a connecting cavity 13 are formed on both sides of the elastic pressure equalizing element 12 in the water inlet cavity. The water inlet cavity 14 is provided with a water inlet 1121 that is connected to the drip irrigation pipe 2. The connecting cavity 13 is provided with multiple connecting ports 1114. Each connecting port 1114 is connected to a turbulent flow channel 1111. The turbulent flow channel 1111 is connected to a water outlet 1112.

[0037] When in use, the water in the drip irrigation pipe 2 flows through the inlet 1121 into the inlet chamber 14, flows through the elastic pressure equalizing member 12 and into the connecting chamber 13, then through the connecting port 1114 into the turbulent flow channel 1111, and then flows out from the outlet 1112.

[0038] In the aforementioned process, when the water pressure is low, the elastic pressure equalizing element 12 deforms less, generating less resistance; when the water pressure is high, the elastic pressure equalizing element 12 deforms more, generating greater resistance. The setting of the elastic pressure equalizing element 12 can effectively stabilize the water pressure, ensure the stability of the water output, and when the elastic pressure equalizing element 12 returns to its original position, it has a backwashing effect, which can play an anti-clogging role.

[0039] When water flows through the turbulent flow channel 1111, the turbulent flow channel 1111 has a good disturbance and turbulence effect, and has a pressure stabilizing effect.

[0040] It is equipped with multiple connecting ports 1114 and multiple turbulent flow channels 1111. In actual use, even if one flow channel is blocked, the other flow channels will still have the function of circulation and will not affect the drip irrigation effect.

[0041] This invention not only has a good pressure equalization effect, ensuring water output regardless of water pressure, but also has a flow channel that has the function of turbulence and flow disturbance, resulting in a significant anti-clogging effect. Furthermore, it employs multiple connecting ports 1114 and multiple turbulent flow channels 1111, so even if one flow channel is blocked, it will not affect the water flow, resulting in a significant drip irrigation effect.

[0042] As an optional implementation, the dripper body 11 includes a first housing 111 and a second housing 112, which are fixedly connected.

[0043] The first housing 111 and the second housing 112 form the water inlet cavity. Specifically, the first housing 111 has an annular body on the side facing the second housing 112, and the second housing 112 has a receiving groove on the side facing the first housing 111. The annular body is sized to fit the receiving groove, and the annular body is inserted into the receiving groove. The inner cavity of the annular body forms the water inlet cavity.

[0044] The turbulent flow channel 1111 and the outlet 1112 are located on the side of the first housing 111 away from the second housing 112; the inlet 1121 is located on the side of the second housing 112 away from the first housing 111. A filter grid 1124 is provided at the position of the inlet 1121. The diameter of the grid holes of the filter grid 1124 is smaller than the diameter of the inlet 1121, which can play a filtering role and further prevent impurities from entering the embedded drip irrigation nozzle 1 and blocking the flow channel.

[0045] As an optional implementation, a guide sleeve 1122 is provided inside the water inlet cavity within the second housing 112. Specifically, the guide sleeve 1122 is inserted into the ring body, and the axial length of the guide sleeve 1122 is less than the axial length of the ring body, so that the inside and outside of the guide sleeve 1122 are connected.

[0046] The inner wall of the flow guide sleeve 1122 is uniformly provided with multiple support blocks 1123 along the circumference. Specifically, three support blocks 1123 are provided. All support blocks 1123 are fixedly connected to the edge of the elastic pressure equalizing member 12. The elastic pressure equalizing member 12 is a circular elastic diaphragm with a diameter smaller than that of the flow guide sleeve 1122. There is a gap between the edge of the elastic pressure equalizing member 12 and the inner wall of the flow guide sleeve 1122. The space between the elastic pressure equalizing member 12 and the water inlet 1121 in the flow guide sleeve 1122 forms a water inlet cavity 14. The gap between two adjacent support blocks 1123 forms a connecting groove that connects the water inlet cavity 14 and the connecting cavity 13. Thus, the water inlet cavity 14 and the connecting cavity 13 are connected.

[0047] As an optional implementation, the connecting port 1114 is connected to the turbulent flow channel 1111 through the water inlet channel 1113, and the water inlet channel 1113 is a straight flow channel.

[0048] The number of connecting ports 1114 and water inlet channels 1113 is set to two, and the two connecting ports 1114 and the two water inlet channels 1113 are symmetrically arranged on both sides of the turbulent flow channel 1111.

[0049] In practical applications, multiple connecting ports 1114, water inlet channels 1113, and turbulent flow channels 1111 can be set and evenly distributed on the dripper body 11.

[0050] As an optional implementation, the turbulent flow channel 1111 is configured as a broken-line flow channel, which has multiple turbulent flow units arranged in sequence. The turbulent flow units adopt a toothed structure, a trapezoidal structure, a rectangular structure or a triangular structure. The figure shows a trapezoidal structure.

[0051] The turbulent flow channel 1111 includes a first turbulent flow section 11111 and a second turbulent flow section 11112. One end of the first turbulent flow section 11111 is connected to the outlet 1112, and the other end of the first turbulent flow section 11111 is connected to the corresponding inlet flow channel 1113 through the second turbulent flow section 11112. The first turbulent flow section 11111, the second turbulent flow section 11112 and the inlet flow channel 1113 form an S-shape.

[0052] As an optional implementation, the two turbulent channels 1111 share a first turbulent section 11111, which is simple and compact in structure while ensuring the turbulence and disturbance effect.

[0054] Example 2 is based on Example 1:

[0056] The drip irrigation device also includes a main water pipe 4, a drip irrigation pipe 2, and a quick-connect switch component 3. An opening 41 is provided on the wall of the main water pipe 4.

The embedded drip irrigation dripper 1 is embedded in the embedding groove 22. The embedding groove 22 is provided with a through hole 21 at the position corresponding to the water outlet 1112.

[0058] The number of drip irrigation pipes 2 and quick-connect switching components 3 is set to at least one, and all drip irrigation pipes 2 are sequentially and evenly connected to the main water pipe 4 through the corresponding quick-connect switching components 3.

[0059] As an optional implementation, the quick-connect component 3 includes a valve component 31 and a first quick-connect component 32.

[0060] The outlet end of the valve assembly 31 is connected to the port of the corresponding drip irrigation pipe 2 via the first quick-connect assembly 32.

[0061] The first quick-connect assembly 32 includes a first spinning sleeve, the outer wall of which is provided with a first actuating block. The first spinning sleeve includes a first threaded sleeve 321 and a clamping sleeve 322 integrally formed along the axial direction. The inner wall of the first threaded sleeve 321 is provided with a first internal thread, and the outer wall of the outlet end is provided with a first external thread. The first threaded sleeve 321 is threadedly connected to the outlet end. The inner wall of the clamping sleeve 322 and the outer wall of the outlet end form an annular conical cavity 323.

[0062] During installation, the port of the drip irrigation tube 2 is inserted into the annular conical cavity 323. The first spinning sleeve is rotated, and the first spinning sleeve moves axially. At this time, the inner wall of the pressing sleeve 322 is displaced relative to the outer wall of the outlet end, thereby pressing the port of the drip irrigation tube 2 onto the outlet end.

[0063] The first quick-connect component 32 not only enables rapid installation with the drip irrigation pipe 2, but also provides a good sealing effect.

[0064] As an optional implementation, the quick-connect switching assembly 3 includes a second quick-connect assembly 33, and the inlet end of the valve assembly 31 is connected to the opening 41 of the main water pipe 4 through the second quick-connect assembly 33.

The second threaded sleeve 331 is threadedly connected to the inlet end. An annular limiting protrusion 311 is provided along the end face of the inlet end. A spiral tooth 312 is integrally provided axially on the annular limiting protrusion 311, and the spiral tooth 312 has half a turn.

[0066] During installation, insert the spiral tooth 312 into the opening 41, rotate the second spinning sleeve, and the second spinning sleeve moves along the inlet end. After the annular limiting eaves 311 are fully inserted into the inside of the opening 41, continue to rotate the second spinning sleeve so that the second threaded sleeve 331 and the annular limiting eaves 311 are pressed against the outer wall and inner wall of the main water pipe 4, respectively. At this time, the installation is completed.

[0067] The second quick-connect component 33 not only enables quick installation with the main water pipe 4, but also provides a good sealing effect.
