Description

Technical Field

[0001] The utility model relates to the technical field of atomizing nozzles, in particular to an atomizing nozzle with adjustable flow rate. Background Art

[0002] Irrigation system is a general term for all levels of ditches or pipelines, as well as corresponding buildings and facilities for water diversion, water transmission, water distribution, water storage and water withdrawal in irrigation areas. It is an engineering system that draws water from water sources and transmits and distributes water to farmland for irrigation through channels, pipelines and ancillary buildings. It can be divided into two types: channel irrigation system and pipeline irrigation system. In pipeline irrigation systems, atomizing nozzles are often required to atomize and spray the water in the pipeline.

[0003] However, the atomizing nozzles commonly used in the prior art can only adjust the water flow intensity and the spray range by rotating the nozzle cap, and do not have the function of independently realizing the water spraying shutdown.

[0004] The Chinese patent with the announcement number CN 218609932 U discloses a novel atomizing nozzle, including a connecting seat, a No. 1 nozzle, a No. 1 sealing ring, a sealing gasket, a No. 2 nozzle, a No. 2 sealing ring, and a nozzle cap. The bottom of the No. 1 nozzle is equipped with a connecting seat, the No. 1 nozzle includes a No. 1 nozzle body, a No. 1 adjusting screw, a No. 1 spray hole, and a No. 1 placement groove. The No. 1 nozzle body is provided with a No. 1 adjusting screw at the periphery, and the No. 1 nozzle body is provided with a No. 1 spray hole and a No. 1 placement groove near the top, and the No. 1 placement groove is located between the No. 1 spray hole and the No. 1 adjusting screw; the No. 2 nozzle includes a No. 2 nozzle body, a No. 2 adjusting screw, a No. 2 spray hole, a No. 2 placement groove, a No. 2 rotating vertical line, and a No. 1 internal thread. The outer bottom of the No. 2 nozzle body is provided with a No. 1 adjusting screw. A No. 2 rotating vertical line is arranged around the circumference, a No. 2 adjusting screw is arranged on the periphery of the No. 2 nozzle body, and the No. 2 adjusting screw is located above the No. 2 rotating vertical line, a No. 2 spray hole and a No. 2 placement groove are arranged near the top of the No. 2 nozzle body, and a No. 1 internal thread used in conjunction with the No. 1 adjusting screw is arranged on the inner side of the bottom of the No. 2 nozzle body; the sealing gasket is located between the No. 1 nozzle and the No. 2 nozzle, and the nozzle cap comprises a nozzle cap body, a water outlet hole, a No. 3 rotating vertical line, and a No. 2 internal thread. The outer circumference of the bottom of the nozzle cap body is provided with a No. 3 rotating vertical line, the top of the nozzle cap body is provided with a water outlet hole, and the inner side of the bottom of the nozzle cap body is provided with a No. 2 internal thread used in conjunction with the No. 2 adjusting screw.

[0005] This patent changes the water output of the nozzle and its opening and closing by adjusting the tightness of the thread to control the degree of squeezing of the sealing gasket. However, the sealing gasket needs to be used with a sealing ring to seal the side wall when in use to prevent water leakage between nozzles No. 1 and No. 2. At the same time, although the sealing gasket with this structure is simple in structure and easy to manufacture, it is easy to slide and shift during use. After long-term use, the nozzle cannot be closed and is prone to water leakage during use.

[0006] Therefore, an atomizing nozzle with adjustable flow rate has become an issue that needs to be solved urgently. Utility Model Content

[0025] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following is a further detailed description of the utility model of an atomizing nozzle with adjustable flow rate in conjunction with the accompanying drawings.

[0027] Combined with Figure 1-4 The specific implementation process of the utility model of an adjustable flow atomizing nozzle is as follows:

[0028] A flow-adjustable atomizing nozzle comprises a base 1, a sealing gasket 2, a middle seat 3 and a cover 4; the base 1 comprises a base body 101, a water inlet 102 and a flow regulating groove 103, the water inlet 102 runs through the upper and lower ends of the base body 101, the flow regulating groove 103 is arranged at the top of the base body 101 and surrounds the outside of the water inlet 102, and the flow regulating groove 103 extends downward from the top to form a ring-shaped deep groove.

[0029] The sealing gasket 2 is sleeved on the upper part of the base body 101, and a flow regulating hole 201 is provided on the top of the sealing gasket 2. The flow regulating hole 201 is connected with the flow regulating groove 103 up and down. Through this alignment method, the water in the water inlet 102 can be discharged from the flow regulating hole 201 after rushing onto the sealing gasket 2 and falling back to the flow regulating groove 103, ensuring that the water flow can flow out normally after the nozzle is turned on.

[0030] The middle seat 3 is sleeved on the outside of the base 1 and is threadedly connected thereto to wrap the sealing gasket 2 inside. A closed ring platform 301 is provided on the upper part of the middle seat 3. When the middle seat 3 and the base 1 are screwed together, the closed ring platform 301 is pressed on the sealing gasket 2 to block the flow regulating hole 201, thereby closing the nozzle. A water outlet 302 is provided on the inner side of the closed ring platform 301. A water spray hole 303 is provided in the side wall of the water outlet 302. After opening, water flows along the water outlet 302 to the water spray hole 303 and sprays into the surface cover 4.

[0031] The surface cover 4 is threadedly connected to the upper part of the middle seat 3. The top of the surface cover 4 is provided with a water outlet 401 connected to the middle seat 3. After the water flows into the surface cover 4, it is sprayed out from the water outlet 401 on the top thereof, thereby completing the entire atomization water spraying process.

[0032] In one embodiment of the present application, in order to prevent the sealing gasket 2 from falling off easily when it is put on the base 1, an annular groove 104 is provided on the base body 101, and the lower part of the sealing gasket 2 protrudes inward and is buckled into the annular groove 104 for fixation, thereby achieving fixed installation of the sealing gasket 2.

[0033] In one embodiment of the present application, in order to better drain and control the water flow, a flow control plate 202 extending into the water inlet 102 is provided on the top of the sealing gasket 2, and the diameter of the flow control plate 202 is smaller than the inner diameter of the water inlet 102, so as to ensure that water can flow through and avoid completely blocking the water inlet 102.

[0034] Preferably, the flow control sheet 202 is truncated cone-shaped with a bottom diameter smaller than a top diameter. This shape enables the water flow to be diverted to both sides in the middle after impacting the flow control sheet 202, so that the water flow can enter the flow regulating groove 103 through the gaps left on both sides.

[0035] In one embodiment of the present application, a baffle 203 extending to the inner edge of the water outlet 302 is provided on the top of the sealing gasket 2, and the baffle 203 is arranged on the inner side of the flow regulating hole 201. The baffle 203 on the inner side can be inserted into the water outlet 302 to contact its inner wall to achieve better matching connection, and can also limit the water flow; a plurality of baffles 203 are provided, and each of them is located between two flow regulating holes 201. This arrangement can divert the sprayed water to ensure that it flows into the water outlet 302 and prevent the water from running wildly.

[0036] In one embodiment of the present application, in order to better achieve the seal between the middle seat 3 and the surface cover 4, a sealing ring groove 304 is provided on the upper part of the middle seat 3, and a sealing ring 305 is provided in the sealing ring groove 304. The sealing ring 305 can be tightly attached to the middle seat 3 and the surface cover 4 to prevent water in the water outlet 302 from leaking out from the threaded connection between the two.

[0037] In one embodiment of the present application, a water outlet groove 306 is provided at the top of the middle seat 3. The water outlet groove 306 is symmetrically arranged about the center of the top surface of the middle seat 3 and is a strip-shaped groove. The water flow rate can also be controlled through the water outlet groove 306, and the water flow can be further atomized. Specifically, the surface cover 4 can be rotated to adjust the distance between the water outlet groove 306 and the inner wall of the top of the surface cover 4, thereby controlling the water flow to the water outlet hole 401.

[0038] Preferably, the water outlet groove 306 extends inward from the outer edge of the middle seat 3 and is arranged from deep to shallow. The water sprayed from the water spray hole 303 flows from the edge of the water outlet groove 306 to the middle direction, and then sprays from the middle to the water outlet hole 401 on the top of the cover 4. The design from shallow to deep can continuously squeeze the water flow to create an atomization effect, while increasing the water flow pressure and the spray range is farther.

[0039] In one embodiment of the present application, the lower outer walls of the base 1, the middle seat 3, and the surface cover 4 are all provided with anti-slip grooves 5. The provision of the anti-slip grooves 5 makes it more convenient to install and disassemble the various components. At the same time, the flow adjustment, opening and closing of the atomizing nozzle are all controlled by adjusting the degree of compression between the components by rotation. The anti-slip grooves 5 can better assist the user to rotate each component, making the operation easier.

[0040] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
