[0028] Figure 1 A perspective structural view of a sprinkler irrigation apparatus according to an embodiment of the present disclosure is shown schematically. Figure 1 As shown, the sprinkler irrigation device 10 includes a body 100, a nozzle 110 disposed on the upper part of the body 100, a mounting assembly 120 disposed on the lower part of the body, and a water inlet pipe 130. Water can be supplied to the nozzle 110 through the water inlet pipe 130, and the sprinkler irrigation device 10 can be installed and fixed by the mounting assembly 120. According to at least one embodiment of this disclosure, the nozzle 110 can rotate relative to the body 100. As an example, the body 100 of the sprinkler irrigation device 10 can be equipped with mechanisms such as a drive motor and transmission gears. The drive motor drives the transmission gears to rotate the nozzle, thereby achieving multi-directional spraying. Furthermore, the body 100 of the sprinkler irrigation device 10 can also be equipped with components such as a water pump and a controller, thereby enabling control of the pressure and / or flow rate of the sprayed water.

[0029] As an example, such as Figure 1 As further shown, the sprinkler head 110 includes a jet nozzle 140 through which water can be sprayed to irrigate objects such as lawns and trees.

[0030] The structure of the sprinkler head for the sprinkler irrigation device according to the present disclosure will be described in detail below with reference to the accompanying drawings.

[0031] Figure 2 A schematic diagram of a nozzle according to an embodiment of the present disclosure is shown. As an example, it can be used... Figure 2 Replace the nozzle 200 shown. Figure 1 The nozzle 110 is shown. (As shown) Figure 2 As shown, the nozzle 200 includes a housing 210, a jet nozzle 220 partially exposed above the housing 210, and a nozzle body (not shown) mainly housed inside the housing 210. The housing 210 provides protection for the jet nozzle and the nozzle body. (Refer to the above...) Figure 1 As described, the nozzle 200 can be relative to the body of the irrigation device ( Figure 2 (Not shown in the image) can be rotated to allow for sprinkler operations within a wider angular range.

[0032] Figure 2 The nozzle retaining ring 230 fitted on the jet nozzle 220 and the nozzle cover plate 240 covering the cover 210 at the outlet position of the jet nozzle 220 are also schematically shown.

[0033] According to embodiments of this disclosure, a sprinkler head for a sprinkler irrigation device may include a sprinkler head body and a jet nozzle. A flow channel is provided within the sprinkler head body. The sprinkler head body includes a connecting end and a flow channel outlet disposed on the end face of the connecting end. The jet nozzle includes an inlet end and a nozzle inlet disposed on the end face of the inlet end. The jet nozzle and the sprinkler head body are detachably connected via a rotatable fastening mechanism between the inlet end and the connecting end, allowing fluid communication between the nozzle inlet and the flow channel outlet.

[0034] Figure 3A This schematically illustrates the structure where the jet nozzle and the nozzle body are assembled together after the housing 210, nozzle retaining ring 230, and nozzle cover plate 240 have been removed. Figure 3A As shown, the jet nozzle 300 and the nozzle body 310 can be sleeved together, so that the water inlet of the jet nozzle and the water outlet of the flow channel of the nozzle body can be fluidly connected.

[0035] Figures 3B to 3C The main structures of the jet nozzle 300 and the nozzle body 310 are schematically shown respectively. Figure 3B As shown, the jet nozzle 300 includes an inlet end 3010 and a nozzle inlet 3020 disposed on the end face of the inlet end; as Figure 3C As shown, a flow channel is provided inside the nozzle body 310. The nozzle body 310 includes a connecting end 3110 and a flow channel outlet 3120 provided on the end face of the connecting end.

[0036] As an example, Figure 3D A schematic diagram showing the disassembly and assembly of the jet nozzle and nozzle body is provided, such as... Figure 3D As shown, the jet nozzle 300 and the nozzle body 310 can be detachably connected by a rotating fastening between the inlet end 3010 and the connecting end 3110 as indicated by the arrow, so that the nozzle inlet of the jet nozzle and the flow channel outlet of the nozzle body can be fluidly connected.

[0037] According to embodiments of this disclosure, a snap fastener can be provided on one of the cylindrical surfaces of the connecting end of the nozzle body and the inlet end of the jet nozzle, while a slot is provided on the other. This allows the inlet end of the jet nozzle and the connecting end of the nozzle body to be rotated into the slot, thus achieving a rotational locking between the nozzle body and the jet nozzle. As an example, the number of snap fasteners and slots is not limited, as long as they can be rotated to achieve a locking mechanism.

[0038] As an example, such as Figure 3DAs further shown, snap fasteners 3030 and 3040 can be provided on the cylindrical surface of the inlet end 3010 of the jet nozzle 300, and corresponding slots 3130 and 3140 can be provided on the cylindrical surface of the connecting end 3110 of the nozzle body 310, so that the connecting end 3110 of the nozzle body 310 can be sleeved on the inlet end 3010 of the jet nozzle 300 by rotating the snap fasteners 3030 and 3040 into the slots 3130 and 3140, thereby forming a... Figure 3A The installation and connection relationship between the jet nozzle 300 and the nozzle body 310 is shown.

[0039] It should be noted that Figure 3D The rotation directions indicated by the arrows are merely illustrative. For example, the jet nozzle can be detached from the nozzle body by rotating it counterclockwise, and installed onto the nozzle body by rotating it clockwise, thus locking the jet nozzle to the nozzle body and allowing fluid communication between the nozzle inlet and the flow channel outlet of the nozzle body. As an example, the rotation direction can be determined based on the relative positional relationship between the latches / slots on the connecting end of the nozzle body and the latches / slots on the inlet end of the jet nozzle, thereby enabling the installation and removal of the jet nozzle from the nozzle body.

[0040] As an example, in addition to using a snap-fit ​​and slot-fitting structure, the jet nozzle and the nozzle body can also be assembled and disassembled by rotating fasteners. Depending on the actual needs, other structures such as threaded structures, magnetic rotating structures, spring pin structures, and torsion lock structures can be selected. No restrictions are imposed here.

[0041] According to embodiments of this disclosure, the nozzle further includes a sealing assembly disposed between the cylindrical inner wall of the connecting end of the nozzle body and the cylindrical outer wall of the inlet end of the jet nozzle.

[0042] Figure 4 The appearance of the nozzle body 310, the jet nozzle 300, and the sealing assembly 320 is schematically shown; Figure 5 A schematic cross-sectional view of a sprinkler head for a sprinkler irrigation apparatus according to an embodiment of the present disclosure is shown. Figure 5 As shown, the sealing component 320 is disposed between the inner cylindrical wall of the connecting end of the nozzle body 310 and the outer cylindrical wall of the inlet end of the jet nozzle 300, which can realize a waterproof and sealed connection between the nozzle inlet of the jet nozzle and the flow channel outlet of the nozzle body.

[0043] As an example, the sealing component can be an O-ring.

[0044] According to embodiments of this disclosure, the jet nozzle may further include a nozzle grid disposed at the nozzle inlet of the jet nozzle. For example... Figure 6As shown, the jet nozzle 300 may include a nozzle grille 350 disposed at its nozzle inlet, which can not only prevent foreign objects from entering the flow channel of the nozzle body, but also shape the water flow ejected from the flow channel outlet of the nozzle body.

[0045] According to at least one embodiment of the present disclosure, in the above-mentioned nozzle, the jet nozzle further includes an outlet end, wherein a nozzle outlet is provided on the end face of the outlet end; the nozzle further includes a nozzle retaining ring, which is detachably sleeved on the outlet end.

[0046] like Figure 7 As shown, the jet nozzle 300 includes an outlet end 3050 and a nozzle outlet disposed on the end face of the outlet end 3050; the nozzle retaining ring 330 is detachably sleeved on the outlet end 3050 of the jet nozzle 300.

[0047] According to at least one embodiment of the present disclosure, the nozzle further includes a nozzle cover plate, wherein the nozzle cover plate is disposed on the outside of the nozzle retaining ring, the nozzle retaining ring is provided with an annular boss, and the nozzle cover plate is provided with an opening that matches the annular boss, the edge of the opening being engaged with the annular boss.

[0048] like Figure 7 As further shown, the nozzle retaining ring 330 is provided with an annular boss, and the nozzle cover plate 340 is provided with an opening that matches the annular boss. By the engagement of the edge of the opening with the annular boss, the nozzle cover plate 340 can be placed on the outside of the nozzle retaining ring 330.

[0049] According to at least one embodiment of the present disclosure, the nozzle further includes a housing, the nozzle body and the jet nozzle are housed within the housing, the housing has an opening, and the nozzle cover is disposed on the opening.

[0050] As an example, such as Figure 8 As shown, the housing includes an upper housing 810 and a bottom housing 820. The bottom housing 820 has a slot on its cylindrical surface. The upper housing 810 includes a top cover 8110 and a front cover 8115 that matches and is installed at the slot of the bottom housing 820. Thus, the upper housing 810 and the bottom housing 820 together enclose a space that can accommodate the nozzle body and the jet nozzle. As an example, an opening is provided at the front cover 8115, through which the outlet end of the jet nozzle 300 is exposed, and a nozzle cover plate 340 is placed over the opening.

[0051] According to embodiments of this disclosure, components such as nozzle cover plates and nozzle retaining rings are detachably connected to the jet nozzles through snap-fitting / fitting, and the jet nozzles are detachably connected to the nozzle body through rotating fasteners. This enables quick and convenient cleaning, maintenance, and / or replacement of nozzle accessories (e.g., jet nozzles, nozzle cover plates, and / or nozzle retaining rings), improving operational efficiency and reducing the operating cost of the irrigation device.

[0052] Figure 9 A schematic mounting structure of the nozzle cover and housing is shown, wherein, for clarity, other components disposed within the housing are omitted. Figure 9 As shown, a locking part is also provided on the inner wall of the upper cover 810 corresponding to the opening 8120, and at least one elastic buckle 3410 is provided on the side of the nozzle cover 340 facing the opening 8120. The locking part includes at least one locking plate 8130, and the at least one elastic buckle 3410 engages with the at least one locking plate 8130.

[0053] According to embodiments of this disclosure, by providing matching engaging parts and snaps, a detachable connection between the nozzle cover and the nozzle housing can be achieved, thereby facilitating the installation and removal of the nozzle cover.

[0054] According to an embodiment of this disclosure, a disassembly opening is provided on the edge of the nozzle cover to facilitate the disassembly and assembly of the nozzle cover and the nozzle head housing. Figure 10 The structure of the nozzle cover is shown, as follows: Figure 10 As shown, a disassembly port 3420 is provided on the lower edge of the nozzle cover plate 340 to facilitate the disassembly of the nozzle cover plate, for example, to facilitate the separation of the nozzle cover plate from the housing and / or the nozzle retaining ring.

[0055] According to at least one embodiment of the present disclosure, the nozzle retainer includes a deformable water flow blocking member that is deformable under the impact of at least part of the ejected water flow to disperse the water ejected by the jet nozzle and adjust the spray range accordingly based on the flow rate of the jet from the jet nozzle, for example, to make the covered spray range more dispersed and uniform.

[0056] For example, such as Figure 11As shown, the nozzle retaining ring 330 includes a water flow blocking member 3310, which is deformable under the impact force of at least a portion of the water flow ejected from the jet nozzle. As an example, the water flow blocking member 3310 can be an elastic baffle. For instance, when the jet nozzle ejects water through the outlet, at least a portion of the ejected water flow can contact the water flow blocking member, and the impact force of the water flow can cause the water flow blocking member to deform; wherein the degree of deformation is related to the magnitude of the impact force of the water flow. As an example, when the impact force of the water flow is greater, for example, when the flow rate / flow rate of the water flow ejected through the outlet is higher, the deformation degree of the water flow blocking member 3310 is greater and it flips outward in the direction away from the outlet, so that the water flow ejected from the outlet is less obstructed, thereby being able to spray to a farther distance and form a larger sprinkler coverage area; conversely, when the impact force of the water flow is reduced, the deformation degree of the water flow blocking member 3310 is reduced, and it elastically returns to its original position in the direction closer to the outlet, which can disperse the water flow ejected from the outlet, thereby enabling the sprayed water flow to form a short-range sprinkler coverage area.

[0057] like Figure 11 As shown, the upper part of the water flow blocking member 3310 is connected to the upper part of the nozzle retaining ring 330.

[0058] As an example, the water flow blocking component 3310 and the nozzle retaining ring 330 can be integrally molded, thereby reducing manufacturing costs and simplifying the installation process.

[0059] like Figure 11 As further shown, the water flow blocking member 3310 has a shape that is wider at the top and narrower at the bottom when projected onto the front of the jet nozzle along the flow channel axis. As an example, Figure 11 The schematic diagram shows the frontal projection of the water flow blocking member 3310 along the axial direction of the jet channel, which presents a triangular shape.

[0060] However, based on the principles of this disclosure, the frontal projection of the water flow blocking member along the axial direction of the jet channel can also present other shapes that are wider at the top and narrower at the bottom, such as an inverted trapezoidal shape, without limitation.

[0061] According to embodiments of this disclosure, a sprinkler irrigation device is also provided, including the above-described sprinkler head, as shown in reference to... Figure 1 As described, the nozzle can rotate relative to the body of the irrigation device.

[0062] According to embodiments of this disclosure, the jet nozzle and the nozzle body are designed to be detachably connected by a rotating snap-fit, and the nozzle retaining ring, nozzle cover plate and jet nozzle are designed to be detachably connected by a snap-fit / fitting mechanism. This allows for quick and convenient cleaning, maintenance and / or replacement of nozzle accessories (e.g., jet nozzle, nozzle cover plate and / or nozzle retaining ring), improving operational efficiency and reducing the operating cost of the irrigation device.

[0063] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "setting," "connection," "linking," "fixing," and "coupling," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communicative connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.
