Description

Technical Field

[0001] The utility model relates to the technical field of atomizing nozzles, in particular to a closable atomizing nozzle. 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 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, and 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.

[0005] The No. 2 nozzle comprises a No. 2 nozzle body, a No. 2 adjusting screw, a No. 2 spray hole, a No. 2 placement groove, a No. 2 rotation vertical line, and a No. 1 internal thread. The No. 2 nozzle body is provided with a No. 2 rotation vertical line in the circumferential direction of the outer periphery of the bottom of the No. 2 nozzle body, and the No. 2 adjusting screw is provided on the outer periphery of the No. 2 nozzle body, and the No. 2 adjusting screw is located above the No. 2 rotation vertical line. The No. 2 nozzle body is provided with a No. 2 spray hole and a No. 2 placement groove near the top, and the No. 1 internal thread used in conjunction with the No. 1 adjusting screw is provided on the inner side of the bottom of the No. 2 nozzle body;

[0006] The sealing gasket is located between the No. 1 nozzle and the No. 2 nozzle. The nozzle cap includes a nozzle cap body, a water outlet, No. 3 rotating vertical lines, and No. 2 internal threads. The outer circumference of the bottom of the nozzle cap body is provided with No. 3 rotating vertical lines. The top of the nozzle cap body is provided with a water outlet. 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.

[0007] This patent can be used to control the intensity and spray range of the sprayed water flow by controlling the tightness of the nozzle cap and the second nozzle; by adjusting the tightness between the first nozzle and the second nozzle, the overlap between the sealing gasket and the first nozzle hole can be adjusted, thereby adjusting the intensity of the water flow, including the supply and shutdown of the water flow. However, the shutdown effect in actual application is not good. Due to multiple rotations, the internal sealing gasket will be misaligned or loose, so that the nozzle hole cannot be effectively closed, which will cause the entire nozzle to leak and cannot be completely closed.

[0008] Therefore, a closable atomizing nozzle becomes a problem that people need to solve urgently. Utility Model Content

[0009] The technical problem to be solved by the utility model is to provide an atomizing nozzle which can effectively adjust the flow rate of the atomizing nozzle and shut it down.

[0010] In order to solve the above technical problems, the technical solution provided by the utility model is: a closable atomizing nozzle, comprising a connecting seat, a nozzle and a nozzle cap; the connecting seat is arranged at the bottom of the nozzle, the nozzle comprises a nozzle seat and a flow control plug, and the flow control plug is inserted into the nozzle seat from the top of the nozzle seat downward;

[0011] The flow control plug includes a baffle and a diverter plug, the diameter of the baffle is larger than the diameter of the water flow channel inside the nozzle seat, the diverter plug is inserted into the water flow channel inside the nozzle seat and extends downward, and the expanded part at the lower end is stuck by the bottom end of the water flow channel inside the nozzle seat and is difficult to be pulled out upward; the diameter of the diverter plug is smaller than the diameter of the water flow channel inside the nozzle seat;

[0026] 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.

[0027] The following is a further detailed description of a closable atomizing nozzle of the utility model in conjunction with the accompanying drawings.

[0028] Combined with Figure 1-7 The specific implementation process of the utility model of a closable atomizing nozzle is as follows:

[0029] A closable atomizing nozzle comprises a connection seat 1, a nozzle 2 and a nozzle cap 3; the connection seat 1 is arranged at the bottom of the nozzle 2 for connecting a water inlet pipe, the nozzle 2 comprises a nozzle seat 21 and a flow control plug 22, and the flow control plug 22 is inserted into the nozzle seat 21 from the top of the nozzle seat 21 downward;

[0030] The flow control plug 22 includes a baffle 221 and a diverter plug 222. The diameter of the baffle 221 is larger than the diameter of the water flow channel 211 inside the nozzle seat 21, ensuring that the baffle 221 is always at the top of the nozzle seat 21 to prevent the entire flow control plug 22 from falling into the water flow channel 211; the diverter plug 222 is inserted into the water flow channel 211 inside the nozzle seat 21 and extends downward, and the expanded portion at the lower end is stuck by the bottom end of the water flow channel 211 inside the nozzle seat 21 and is difficult to be pulled upward. The diverter plug 222 is inserted into the water flow channel 211 to adjust the water output, and at the same time, the expanded portion is used to resist the bottom end of the water flow channel 211 to prevent the diverter plug 222 from being washed out by the water flow; the diameter of the diverter plug 222 is smaller than the diameter of the water flow channel 211 inside the nozzle seat 21, and the diameter of the diverter plug 222 is slightly smaller to allow water to pass through, avoiding completely blocking the water flow channel 211;

[0031] The nozzle cap 3 is sleeved on the outside of the nozzle 2 and is threadedly connected thereto. The degree of compression of the nozzle cap 3 on the flow control plug 22 is adjusted by means of threaded connection, thereby controlling the water spraying amount of the entire nozzle 2 and realizing the opening and closing of the nozzle; a water spray hole 31 is provided on the nozzle cap 3, and atomized water is sprayed out through the water spray hole 31 to realize irrigation.

[0032] In one embodiment of the present application, the water flow will be blocked when it hits the diverter plug 222. Therefore, in order to allow more water flow to be ejected, a diverter channel 2221 is provided in the middle of the diverter plug 222, so that the water flow can enter the diverter channel 2221 after hitting the diverter plug 222. The diverter channel 2221 extends all the way to a position close to the baffle 221. After the water in the diverter channel 2221 reaches the end of the diverter channel 2221, it is ejected from the gap between the diverter plug 222 and the water flow channel 211. 221 divides the diverter plug 222 evenly into three insert pieces 2222, and an expansion head 2223 is provided at the end of each insert piece 2222. The expansion head 2223 allows the lower end of the diverter plug 222 to press against the bottom end of the water flow channel 211 to prevent the diverter plug 222 from being washed out of the water flow channel 211 by the water flow. At the same time, since the diverter plug 222 is provided with a diverter channel 2221, each insert piece 2222 can be squeezed and bent, thereby facilitating the entire diverter plug 222 to be inserted into the water flow channel 211 and to be pulled out by force.

[0033] In one embodiment of the present application, after the water flows into the water flow channel 211, in order to facilitate its discharge, the length of the diverter plug 222 is made greater than the length of the water flow channel 211 inside the nozzle seat 21 and a certain distance is left between the top of the expansion head 2223 and the bottom of the water flow channel 211 inside the nozzle seat 21. The existence of this distance allows the bottom of the baffle 221 and the top of the nozzle seat 21 to be separated under the impact of the water flow, thereby allowing the water in the water flow channel 211 to be quickly sprayed out.

[0034] Preferably, the diverter plug 222 is covered with a gasket 223, which is located between the nozzle seat 21 and the baffle 221. After the nozzle cap 3 is tightened, the gasket 223 achieves close contact between the nozzle seat 21 and the baffle 221 to ensure that the nozzle no longer leaks water after closing.

[0035] In one embodiment of the present application, in order to enhance the atomization effect of the nozzle, an atomizing groove 2211 is provided on the top of the baffle 221, and a water inlet groove 2212 is provided on the edge of the atomizing groove 2211. The water sprayed out of the water flow channel 211 enters the atomizing groove 2211 from the water inlet groove 2212, and is squeezed, blocked, and reversed multiple times to make the water flow speed faster and have an atomized form. After entering the atomizing groove 2211, it is sprayed out from the water spray hole 31 of the nozzle cap 3.

[0036] Preferably, two water inlet grooves 2212 are provided and are centrally symmetrically arranged.

[0037] In one embodiment of the present application, a detachable sealing rubber ring 4 is provided on the nozzle seat 21, and the sealing ring is used to enhance the sealing effect between the nozzle seat 21 and the nozzle cap 3 to avoid water leakage from the connection between the two.

[0038] Preferably, the nozzle seat 21 is threadedly connected to the nozzle cap 3 .

[0039] In one embodiment of the present application, since the entire atomizing nozzle adopts multiple components, in order to facilitate the installation of the various components and facilitate the adjustment of the water flow intensity, anti-slip patterns 5 are provided on the outer walls of the connecting seat 1, the nozzle seat 21 and the nozzle cap 3. By increasing the friction, the convenience of relative rotation operation between the various components is improved.

[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.
