[0025] The utility model will be further described in combination with specific embodiment:

[0026] The windproof nozzle comprises an outer shell 1, a flow guide base 2 and a spray gasket 3. The outer shell 1 is in a whole columnar shape, one end of which is open and an inner cavity is formed in the outer shell 1. The flow guide base 2 is in a columnar shape, which is inserted into the outer shell 1 from the open end of the outer shell 1. A first flow guide channel 21 is formed in the center of the flow guide base 2, and a liquid inlet 23 is arranged at the outer end of the first flow guide channel 21. A second flow guide channel 22 is formed between the outer wall of the flow guide base 2 and the outer shell 1. A sealing groove 26 is arranged around the outer wall of the flow guide base 2, and a sealing ring 27 is arranged in the sealing groove 26. When the flow guide base 2 is inserted into the outer shell 1, the sealing ring 27 is used to seal between the outer shell 1 and the flow guide base 2, to seal one end of the second flow guide channel 22, and to outwardly expand the outer shell 1 through the sealing ring 27, so as to tightly connect the outer shell 1 and the flow guide base 2. A first flow-through opening 24 is formed in the outer wall of the flow guide base 2, which communicates the first flow guide channel 21 and the second flow guide channel 22.

[0027] With specific reference Figure 1 、 2 , the top of the outer shell 1 is provided with a spray opening 11, which is circular. In fact, a flow guide platform 28 is arranged at the top of the flow guide base 2, and a flow guide ring wall 281 is arranged at the outer edge of the flow guide platform 28, and a second flow-through opening 282 is formed in the flow guide ring wall 281. The flow guide platform 28 faces the spray opening 11. In use, the windproof nozzle in the patent sprays liquid outwardly through the spray opening 11. The liquid enters the first flow guide channel 21 through the liquid inlet 23, enters the second flow guide channel 22 through the first flow-through opening 24, enters the flow guide platform 28 through the second flow-through opening 282, and then sprays outwardly through the spray opening 11.

[0028] The spray gasket 3 is fixed in the spray opening 11, and an atomizing spray opening 33 is formed in the spray gasket 3. The edge of the spray gasket 3 is provided with an abutting boss 31, and the outer edge of the spray opening 11 is provided with an abutting groove 12 opposite to the abutting boss 31. Figure 2 、 3As shown, the spray pad 3 in this patent is made of stainless steel and is circular in shape. The abutment protrusion 31 is arranged around the outer edge of the spray pad 3. The abutment groove 12 is formed inside the nozzle 11 of the outer shell 1. During installation, the spray pad 3 is placed inside the outer shell 1, and the abutment protrusion 31 on the outer edge of the spray pad 3 is engaged with the abutment groove 12 to achieve the installation of the spray pad 3. The size of the spray pad 3 is adapted to the size of the nozzle 11. When the spray pad 3 is installed in the nozzle 11, the spray pad 3 and the nozzle 11 fit tightly together to increase the stability of the spray pad 3 after installation. In addition, after the flow guide 2 is installed in the outer shell 1, it can further abut against the spray pad 3 to achieve further fixation.

[0029] In this patent, the spray pad 3, during installation, achieves quick positioning by abutting the protrusion 31 and abutting the groove 12 against each other, reducing the assembly difficulty of the spray pad 3. Furthermore, the spray pad 3 is provided with an annular inclined groove 32 located outside the atomizing nozzle 33. Further, both ends of the atomizing nozzle 33 are provided with annular slit grooves 14. When the windproof nozzle in this patent is used, water flows into the atomizing nozzle 33 along the annular inclined groove 32 at the lower end of the atomizing nozzle 33. The water flow is gathered by the annular inclined groove 32 and then sprayed out from the atomizing nozzle 33, increasing the water output to enhance the windproof effect. Simultaneously, the water is sprayed outwards through the annular inclined groove 32 on the other side of the spray pad 3, increasing the spray area and enhancing the spray effect.

[0030] Furthermore, the bottom of the flow guide seat 2 is provided with a first connecting boss 25, and the bottom of the outer shell 1 is provided with a second connecting boss 13. When the flow guide seat 2 is fixed inside the outer shell 1, the second connecting boss 13 abuts against the first connecting boss 25, and the flow guide seat 2 and the outer shell 1 are tightly connected by the abutment of the sealing ring 27.

[0031] Furthermore, the outer casing 1 has faceted grooves 14 on both sides, and the top of the outer casing 1 has inclined arc-shaped surfaces 15 located on both sides of the faceted grooves 14. The faceted grooves 14 are generally right-angled, making the cross-section of the outer casing 1 generally flat and strip-shaped. Existing mounting bases for installing windproof nozzles mostly have circular mounting openings, whereby the windproof nozzle is installed in the mounting base, the outer casing 1 passes through the mounting opening, and the first connecting boss 25 abuts against the mounting base for fixation. This patent, by setting faceted grooves 14, reduces the size of the cross-section of the outer casing 1, and the inclined arc-shaped surfaces 15 allow the top of the outer casing 1 to slide more easily into the mounting base along the mounting opening, reducing assembly difficulty. Moreover, the outer casing 1 with faceted grooves can be used with both mounting bases with circular and square mounting openings, making it more flexible in use.
