Please refer to the figures, which show an embodiment of the dual-flow nozzle of the present invention. However, these embodiments are for illustrative purposes only and are not limited to this structure in patent applications.

As shown in Figures 1 to 8, the first embodiment of the dual-outlet showerhead comprises a main base 10, a screw cap 20, and a tubular flow divider 30. A flow channel 11 is formed within the main base 10. One end of the flow channel 11 extends to the front end of the main base 10, and the other end of the flow channel 11 extends to the exterior of the main base 10. This connects the flow channel 11 to a water supply pipe (not shown) used to transport irrigation water, allowing the water to flow through the water supply pipe into the flow channel 11. A threaded connection 12 is formed on the exterior front end of the main base 10.

The screw cap 20 is screwed onto the screw portion 12, and the front end of the screw cap 20 radially forms a ring portion 22.

The diverter 30 is disposed at the front end of the main seat 10. The diverter 30 is positioned opposite the main seat 10 and is located inside the screw cap 20. A first chamber 41 is formed inside the diverter 30 and is connected to the flow channel 11. A second chamber 42 is formed between the radial outer portion of the diverter 30 and the inner circumferential wall of the screw cap 20. A plurality of diverter channels 43 are respectively connected to the first chamber 41 and the second chamber 42. The number of the diverter channels 43 can be increased or decreased as needed. The diversion channel 43 is limited to at least one. In this example, each diversion channel 43 is formed radially through the diversion member 30. The front end of the diversion member 30 radially forms a front plate 31. The front plate 31 passes through a first water outlet 44 and connects to the first chamber 41. An annular second water outlet 45 is formed between the front end of the diversion member 30 and the annular portion 22 and connects to the second chamber 42. Water is discharged outward through the first and second water outlets 44 and 45.

The water supply pipe supplies irrigation water into the main seat 10. The water flows through the flow channel 11 into the first chamber 41. Then, a portion of the water is sprayed forward in a cone shape toward the front of the front plate 31 through the first water outlet 44 to form a water mist. The remaining portion of the water is diverted through the respective branch channels 43 to enter the second chamber 42. Thereafter, it is sprayed outward in a cone shape around the periphery of the front plate 31 through the second water outlet 45 to form a water mist. Rotating the screw cap 20 to move it forward or backward changes the radial width and shape of the second water outlet 45 defined by the screw cap 20 and the diverter 30, thereby changing the distribution range and shape of the water mist sprayed outward through the second water outlet 45.

Water flows through the first chamber 41 and the second chamber 42, forming dual outlet paths: one directional and one variable. Water is then sprayed outward through the first outlet 44 and the second outlet 45, respectively. Adjusting the screw cap 20 allows the spray from the second outlet 45 to create a wider range of water mist. This facilitates the interaction between the variable and directional water mists due to contact.

The components of the diverter 30 that facilitates water diversion are simplified, and the connection and positioning between the diverter 30 and the main base 10 are simplified, making assembly and disassembly of the diverter 30 and the main base 10 easy.

The diverter 30 has two radially protruding hooks 32, and the main seat 10 has two recesses 13. Each hook 32 elastically fits into each recess 13, positioning the diverter 30 relative to the main seat 10.

The main seat 10 forms an annular stop surface 14, and the end of the diverter 30 away from the front plate 31 abuts against the stop surface 14.

The inner part of the diverter 30 is optionally provided with a guide member 50, the front end of the guide member 50 is against the rear side of the front plate 31, the radial outer periphery of the guide member 50 is recessed with two guide grooves 52 respectively connected to the first chamber 41, the guide member 50 is recessed with a confluence groove 54 and two connecting grooves 56 on the side facing the front plate 31, the confluence groove 54 is connected to the first water outlet 44, and the connecting grooves 56 are respectively connected to the guide grooves 54 and the first water outlet 44. After entering the first chamber 41, water is further divided and flows through the guide grooves 52 and the connecting grooves 56 before converging into the converging groove 54. Water is then sprayed outward through the first water outlet 44. By guiding the water entering the first chamber 41 through the guide member 50 and then converging it through the first water outlet 44, the atomization of the water sprayed outward through the first water outlet 44 is improved.

As shown in Figure 9, the main difference between the second embodiment and the first embodiment is that each of the diverter channels 43 is located on both sides of each of the hooks 32, and each of the diverter channels 43 extends to the end of the diverter member 30 away from the front plate 31.

As shown in Figures 10 to 12, the third embodiment differs from the first embodiment in that the front plate 31 is penetrated by a plurality of first water outlets 44, each of which is distributed around the center of the front plate 31. A plurality of diversion grooves 33 are recessed into the rear side of the front plate 31, each of which is connected to a respective first water outlet 44 and extends to converge at the center of the front plate 31. A channel 58 is axially penetrated through the guide member 50. One end of the channel 58 is connected to the first chamber 41, and the other end of the channel 58 is connected to each of the diverter grooves 33. Water flows from the first chamber 41 through the channel 58 into each of the diverter grooves 33, where it is guided by each of the diverter grooves 33 toward each of the first water outlets 44. The water is then sprayed outward through each of the first water outlets 44 to form multiple directional water mists. Each of the diverter grooves 33 can enhance the atomization of the water mist sprayed outward through each of the first water outlets 44.

As shown in Figures 13 and 14 , the fourth embodiment differs from the first embodiment primarily in that two locking buckles 15 protrude from the front end of the main base 10 . Each locking buckle 15 is integrally formed with an anchor portion 152 and a buckle portion 154 . The width of each anchor portion 152 is smaller than the width of the buckle portion 154 to which it is connected, and each buckle portion 154 is located at the front end of the anchor portion 152 to which it is connected.

The diverter 30 cooperates with each of the locking buckles 15 to penetrate two through-slots 34. Each through-slot 34 is formed by a first slot 342 and a second slot 344. Each of the locking portions 154 fits into each of the first slots 342, while each of the connecting portions 152 fits into each of the second slots 344. The diverter 30 forms two abutment surfaces 35, each located on the side of each of the first slots 342 facing away from the first water outlet 44. Each of the locking portions 154 abuts against each of the abutment surfaces 35, thereby positioning the diverter 30 relative to the main seat 10.

The fourth embodiment does not require the hook 32 or the slot 13 for the hook 32 to fit into as in the first embodiment. Instead, the hooks 15 and the slots 34 are spatially aligned. The diverter 30 is slidably mounted on one side of the main base 10. The hooks 15 and the diverter 30 form a relative constraint, thereby positioning the diverter 30.

As shown in FIG13 , the fifth embodiment differs from the fourth embodiment in that each first groove portion 342 further extends toward the front plate 31 , thereby forming a respective flow channel 43 .
