[0015] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0017] refer to Figures 1 to 9 The present invention includes a flow channel body 2 clamped on the bottom of the outer shell 1, and a gasket 3 is installed on the bottom of the flow channel body 2; The outer shell 1 includes an outermost base shell 101 and a guide shell 102 integrally connected thereto. The guide shell 102 is hollow inside. The upper half of the side of the guide shell 102 is not connected to the base shell 101, and the lower half of the side is provided with an internal air intake gap 105. The top of the guide shell 102 is provided with a flat nozzle 103, which serves as the base of the nozzle hole 104. The center of the nozzle 103 is provided with a semicircular nozzle hole 104, which serves as an outlet for water jetting. The flow channel body 2 is supported by a circular base 201, with a clamping ring 202 disposed above it. The two are integrally formed into a "convex" structure, serving as a clamping medium and a place for water and air to react. A long columnar flow guide 203 is disposed above the clamping ring 202. The gasket ring 3 includes a hollow rubber pad body 301, the bottom of which is protruding as an inlet, through which water or other liquids to be sprayed enter. The middle of the gasket ring 3 is penetrated by an inlet cavity 303 from top to bottom, and a concave ring-shaped blister cavity 302 is provided on the upper end surface of the rubber pad body 301.

[0018] The interior of the guide shell 102 is divided into a limiting cavity 1021, a speed increasing cavity 1022 and a pre-spray cavity 1023 from bottom to top, and the diameters decrease in sequence. Figure 9 , which plays the role of connecting and providing channels for all parties.

[0019] The cutout of the nozzle hole 104 is V-shaped with an included angle of 21.59 degrees, and can spray a fan-shaped surface with an angle of 110 degrees to both sides, which is the included angle of the sprayed bubble mist.

[0020] The guide body 203 is provided with a guide cavity 2031 that is wide at the top and narrow at the bottom. The Bernoulli principle is used to gradually slow down the flowing liquid to prevent the flow rate from being too fast. The base 201 and the clamping ring 202 are provided with a mixing cavity 2011 that is connected to the guide cavity 2031, which mainly serves as a space for the fusion of water and air (air bubbles). The upper end surface of the clamping ring 202 is evenly provided with three groups of arc-shaped air grooves 2021 that pass through from top to bottom. After the water passes through the inlet cavity 303 and the guide cavity 2031, its high-speed water flow will cause the air grooves 2021 and the air intake gap 105 to generate negative pressure, forcing the outside air to enter and mix with the water. Moreover, since the air grooves 2021 are located beside the flow channel and are connected to the mixing cavity 211 only through the thinner bubble cavity 302 (refer to Figure 10 ), so water overflow will not occur.

[0021] After the flow channel body 2 is snapped into the interior of the outer shell 1, the outer wall of the flow guide 203 is interference fit with the inner wall of the speed increasing cavity 1022 to prevent it from falling off. The flow guide 203 does not contact the inner wall of the limiting cavity 1021. The outer wall of the retaining ring 202 is interference fit with the inner wall of the base shell 101, and the lower end face of the base shell 101 abuts against the upper end face of the base 201.

[0022] When the gasket ring 3 is clamped in the mixing cavity 2011 at the bottom of the flow channel body 2, the outer wall of the rubber pad body 301 is clamped with the inner wall of the mixing cavity 2011, and the lower end surface inside the clamping ring 202 is in contact with the upper end surface of the rubber pad body 301.

[0023] A protruding fastening ring 106 is provided on the inner wall of the bottom of the base shell 101 , and the fastening ring 106 is interference-fitted with the outer wall of the clamping ring 202 .

[0024] The working principle of the present invention is: High-pressure water flows into the inlet chamber 303 and enters the bubble chamber 302, where it mixes with the air entering under negative pressure to produce bubbles. The water containing the cheongsam then enters the diversion chamber 2031 and gradually decelerates, and then enters the speed-increasing chamber 1022. When it passes through the speed-increasing chamber 1022 to the pre-spray chamber 1023, it is instantly accelerated (Bernoulli principle). In addition, since the semicircular nozzle hole 104 is sprayed out at an accelerated speed as the diameter decreases when the water flows through it, the water mixed with bubbles will produce a bubble mist with an angle of 110 degrees when it is sprayed out. That is, the water droplets in the sprayed mist are bubbles containing air. The pressure of the nozzle can reach 200 MPa and can still maintain stable fan-shaped diffusion. The bubbles explode when they approach or touch the crops being sprayed, further expanding the spraying area and coverage diameter.

[0025] The 110-degree cross-angle spraying creates no-dead-angle coverage and reduces atomization drift caused by wind.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
