Description

Technical Field

[0001] This utility model relates to the field of spraying equipment, specifically to a dual-mode jet nozzle. Background Technology

[0002] Current garden sprayers mostly employ a fixed radial spray pattern, which, while capable of basic irrigation, has significant drawbacks: its planar water flow is ill-suited to the three-dimensional irrigation needs of tree branches and shrub roots, resulting in insufficient deep wetting; the fixed scattering range easily leads to water waste and accidental spraying of non-target areas; and wind interference can exacerbate uneven irrigation, causing the risk of localized waterlogging. While existing adjustable spraying devices have attempted improvements, their complex structure, low adjustment precision, and susceptibility to clogging make them unsuitable for long-term stable use. There is an urgent need to develop a spraying structure that can dynamically adapt to plant morphology and regulate water flow trajectory to improve garden maintenance efficiency. Utility Model Content

[0005] A dual-mode jet nozzle, comprising:

[0006] A nozzle holder, wherein a nozzle cover is fixedly provided at the front end of the nozzle holder, and a spray mesh is fixedly provided on the inner side of the front end of the nozzle cover, and a direct spray hole is provided at the center of the spray mesh;

[0007] The valve body includes a valve body body and a direct injection pipe fixed at the center of the front end of the valve body body. The front end of the direct injection pipe is fixedly connected to the spray mesh around the direct injection hole. The valve body body is provided with a first water guide hole communicating with the inside of the direct injection pipe and a second water guide hole communicating with the outside of the direct injection pipe. The first water guide hole and the second water guide hole are spaced apart along the circumferential direction around the central axis of the valve body body.

[0008] The valve core is movably fitted inside the rear end of the nozzle seat and rotates with the valve body. The valve core has a third water guide hole. The first water guide hole and the second water guide hole rotate circumferentially with the nozzle seat and form a periodic coupling and communication with the third water guide hole.

[0009] To better achieve the above technical solution, optionally, the rear end of the nozzle cover and the front end of the nozzle seat are connected by threads.

[0010] Optionally, a first sealing ring that mates with the inner circumferential surface of the nozzle cover is provided around the middle of the outer peripheral surface of the spray mesh.

[0011] Optionally, it also includes a connecting pin, wherein the valve core has a pin hole at its center, and the pin end of the connecting pin moves through the pin hole and is fixed at the center of the rear end of the valve body.

[0012] Optionally, the valve body has an arc groove located outside the circumference of the first water guide hole and the second water guide hole and coaxial with it. The front end of the valve core is provided with a guide post. The front end of the guide post is located in the arc groove and slides with the arc groove. When the guide post is located at one end of the arc groove, the first water guide hole and the third water guide hole overlap and communicate with each other.

[0015] Optionally, the front end of the direct injection pipe is provided with a foamer.

[0016] Optionally, a second sealing ring is provided between the outer peripheral surface of the valve body and the inner peripheral surface of the nozzle seat.

[0017] The beneficial effects of this utility model are:

[0018] This utility model discloses a dual-mode jet nozzle. Rotating the nozzle seat or nozzle cover as a single unit rotates the valve body. When the first and third water guide holes are connected, water from the valve core enters the direct spray pipe through the third and first water guide holes, and then exits through the direct spray holes, forming a direct jet. This is suitable for scenarios requiring powerful rinsing or centralized water supply. When the second and third water guide holes are connected, water from the valve core enters the cavity formed by the direct spray pipe, valve body, nozzle seat, and nozzle cover through the third and second water guide holes, and then exits through the holes in the spray mesh, forming a spray pattern suitable for large-area irrigation and sprinkler applications. This dual-mode jet nozzle offers two selectable modes: diffused spray and axial focused jet. Users can freely switch between these modes according to their needs, thereby improving the performance and meeting diverse user requirements for water flow patterns and functions in different scenarios.

Detailed Implementation

[0029] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0030] Please see Figures 1 to 8 This utility model discloses a dual-mode jet nozzle, including: a nozzle seat 10, a nozzle cover 20, a spray mesh 30, a valve body 40, and a valve core 50.

[0031] like Figure 1-3 As shown, a nozzle cover 20 is fixedly provided at the front end of the nozzle seat 10, and a spray mesh 30 is fixedly provided on the inner side of the front end of the nozzle cover 20. A direct spray hole 301 is provided in the center of the spray mesh 30.

[0032] Specifically, a first sealing ring 302 is provided around the center of the outer circumference of the spray mesh 30, which mates with the inner circumference of the nozzle cover 20. More specifically, a first mounting groove is provided around the center of the outer circumference of the spray mesh 30. The inner side of the first sealing ring 302 is placed in the first mounting groove, and the outer side protrudes from the first mounting groove. The first sealing ring 302 ensures a sealed connection between the outer circumference of the spray mesh 30 and the inner circumference of the nozzle cover 20, effectively preventing water leakage from the connection between the spray mesh 30 and the nozzle cover 20, and improving the sealing performance and water utilization efficiency of the entire nozzle. The inner circumference of the rear end of the nozzle cover 20 is provided with an internal thread, and the outer circumference of the front end of the nozzle seat 10 is provided with an external thread. The internal and external threads mate to allow the nozzle seat 10 and the nozzle cover 20 to be detachably connected, facilitating the maintenance and replacement of the internal components of the nozzle and improving the maintainability of the product.

[0033] like Figures 2 to 8 As shown, the valve body 40 includes a valve body 41 and a direct spray pipe 42 fixed at the center of the front end of the valve body 41. The front end of the direct spray pipe 42 is fixedly connected to the spray mesh 30 around the direct spray hole 301. The valve body 41 is provided with a first water guide hole 411 communicating with the inside of the direct spray pipe 42 and a second water guide hole 412 communicating with the outside of the direct spray pipe 42. The first water guide hole 411 and the second water guide hole 412 are spaced apart along the circumferential direction around the central axis of the valve body 41. Specifically, the first water guide hole 411 and the second water guide hole 412 are both arc-shaped, and the central angle of the first water guide hole 411 and the second water guide hole 412 is 30°-60°. The valve core 50 is movably fitted inside the rear end of the nozzle cover 20 and rotates with the valve body 40. The valve core 50 has a third water guide hole 501. The first water guide hole 411 and the second water guide hole 412 rotate circumferentially with the nozzle seat 10 and form a periodic coupling and conduction with the third water guide hole 501. Through the periodic coupling and conduction, the dual-mode jet nozzle can flexibly switch between spraying and direct current modes, which meets the needs of water flow mode in different application scenarios and greatly improves the applicability of the product.

[0034] In this embodiment of the invention, a dual-mode jet nozzle is used by rotating the nozzle seat 10 or the nozzle cover 20. The integrated rotation of the nozzle seat 10 and the nozzle cover 20 drives the valve body 40 to rotate. When the first water guide hole 411 is connected to the third water guide hole 501, the water in the valve core 50 enters the direct spray pipe 42 through the third water guide hole 501 and the first water guide hole 411, and then sprays out through the direct spray hole 301 to form a direct jet. This can be used in scenarios requiring strong rinsing or centralized water supply, improving cleaning efficiency and water supply effect. When the second water guide hole 412 is connected to the third water guide hole 501, the water in the valve core 50 enters the cavity formed by the direct spray pipe 42, the valve body 41, the nozzle seat 10, and the nozzle cover 20 through the third water guide hole 501 and the second water guide hole 412, and is sprayed out through the holes of the spray mesh 30 to form a spraying mode. This is suitable for large-area irrigation, spraying, and other scenarios, expanding the coverage range of the water flow.

[0035] This utility model provides a dual-mode jet nozzle with two selectable modes: diffuse jet and axial focused jet. Users can freely switch between diffuse jet and axial focused jet modes according to their needs, thereby improving the performance and meeting the diverse needs of users for water flow patterns and functions in different scenarios.

[0036] In an embodiment of this utility model, the inner wall of the rear end of the valve core 50 has an internal threaded connection part 503. The dual-mode jet nozzle is directly connected to the spray pipe through the internal threaded connection part 503, thereby fixing the valve core 50. This connection method is not only convenient and quick to install, but also ensures a stable connection between the valve core 50 and the spray pipe, preventing loosening or leakage under water flow impact, and improving the stability of the entire system.

[0037] like Figure 5-7 As shown, in this embodiment of the present invention, a connecting pin 60 is also included. The valve core 50 has a pin hole 505 at its center. The pin end of the connecting pin 60 moves through the pin hole 505 and is fixed to the center of the rear end of the valve body 41. The cap end of the connecting pin 60 moves against the rear end face of the pin hole 505. Specifically, a first hollow column 504 is provided around the pin hole 505 at the center of the valve core 50, and a second hollow column 414 is provided on the valve body 41. The connecting pin 60 is rotatably engaged with the first hollow column 504 and fixedly connected to the second hollow column 414, so that the valve body 40 can only rotate relative to the valve core 50 and cannot move axially. This ensures the relative position stability between the valve body 40 and the valve core 50, ensures accurate communication between the water guide holes, and improves the reliability of dual-mode switching.

[0038] In an embodiment of this utility model, the valve body 41 is provided with an arc groove 413 located on the outer side of the first water guide hole 411 and the second water guide hole 412 and coaxial with it. The front end of the valve core 50 is provided with a guide post 502. The front end of the guide post 502 is located in the arc groove 413 and slides with the arc groove 413. When the guide post 502 is located at one end of the arc groove 413, the first water guide hole 411 and the third water guide hole 501 overlap and communicate. When the guide post 502 is located at the other end of the arc groove 413, the second water guide hole 412 and the third water guide hole 501 overlap and communicate. Specifically, the second water guide hole 412 and the third water guide hole 501 have the same central angle. When the valve body 40 rotates, the first water guide hole 411 or the second water guide hole 412 connects with the third water guide hole 501 to achieve seamless switching. The cooperation between the arc groove 413 and the guide post 502 plays a role in precise guidance and positioning, making the switching between water guide holes smoother and more accurate, avoiding the problem of water flow interruption or leakage during the switching process, and improving the stability and smoothness of dual-mode switching.

[0039] In the embodiments of this utility model, there are two of each of the first water guide hole 411, the second water guide hole 412, the third water guide hole 501, the arc groove 413, and the guide post 502, which are symmetrically arranged along the central axis of the valve body 40. The two first water guide holes 411, the second water guide hole 412, and the third water guide hole 501 can increase the water flow rate and meet the needs of large flow rates. The two arc grooves 413 and the guide post 502 can make the force uniform and stable, reduce the wear and deformation of the components during rotation, and extend the service life of the product.

[0040] like Figure 4 , 5 As shown in Figures 6 and 8, in the embodiments of this utility model, a sealing mesh frame 80 is provided on the mating surface of the valve core 50 and the valve body 41. The first water guide hole 411, the second water guide hole 412, and the third water guide hole 501 are all located within the sealing mesh frame 80. Specifically, the sealing mesh frame 80 includes an inner ring sealing ring 801, an outer ring sealing ring 802, and a sealing rod portion 803 connecting the inner ring sealing ring 801 and the outer ring sealing ring 802. Preferably, there are four sealing rod portions 803, which form four cavities. The two third water guide holes 501 have forward-extending protruding ring portions 506, which are engaged in the two cavities to fix the sealing mesh frame 80. The sealing mesh frame 80 can improve the sealing performance of the first water guide hole 411, the second water guide hole 412, and the third water guide hole 501, effectively preventing water leakage around the water guide holes and improving the utilization rate of water flow and the working efficiency of the system.

[0041] In an embodiment of this utility model, a foamer 70 is provided at the front end of the direct spray pipe 42. The foamer 70 enables the water flow to form foam when it is sprayed out, which reduces the impact force of the water flow, avoids water splashing, and at the same time reduces the noise generated when the water flow is sprayed, thus improving the comfort of use.

[0042] In an embodiment of this utility model, a second sealing ring 43 is sandwiched between the outer peripheral surface of the valve body 40 and the inner peripheral surface of the nozzle seat 10. The second sealing ring 43 further enhances the sealing performance between the valve body 40 and the nozzle seat 10, prevents water from leaking from the gap between the two, and improves the waterproof performance and reliability of the entire nozzle.

The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
