Description

Technical Field

[0001] This disclosure relates to the field of intelligent irrigation, specifically to a sprinkler head for a sprinkler irrigation device and a corresponding sprinkler irrigation device. Background Technology

[0002] With the increasing demand for smart irrigation in landscaping, gardening, and home gardens, various sprinkler systems have emerged. For example, currently, lawns in home gardens typically use either buried automatic irrigation systems or traditional systems that use water pipes and sprinklers for automatic irrigation. However, buried automatic irrigation systems are costly to construct and complex to install, generally requiring the excavation of the lawn, laying of pipes, and placement of multiple sprinklers on the pipes to ensure complete coverage of the entire lawn. Traditional water pipe and sprinkler systems, on the other hand, have limited coverage areas for individual sprinklers, typically around 100 square meters. To completely cover the entire lawn, individual sprinklers need to be frequently moved, increasing workload and operating costs. Utility Model Content

[0024] Furthermore, dimensions may be exaggerated in the accompanying drawings for clarity and are not drawn to scale. Throughout the drawings, the same reference numerals generally refer to the same elements.

[0025] Figure 1 A perspective structural view of a sprinkler irrigation apparatus according to an embodiment of the present disclosure is shown schematically. Figure 1As 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.

[0026] 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.

[0027] According to embodiments of this disclosure, a sprinkler head for a sprinkler irrigation device may include a housing and a jet nozzle at least partially located within the housing. The jet nozzle includes an inlet and a first outlet, and the housing includes a second outlet. The first outlet and the second outlet are at least partially connected. The sprinkler head also includes a removable nozzle cover disposed at and detachably connected to the first outlet. The nozzle cover is capable of changing the direction of the water jet from the first outlet.

[0028] The structure of the nozzle according to the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0029] Figure 2 A schematic diagram of a nozzle according to an embodiment of the present disclosure is shown. Figure 2 As shown, the nozzle 110 includes a jet nozzle 210, a removable nozzle guard 220, and a housing 230 that can accommodate at least a portion of the jet nozzle 210 to protect the jet nozzle.

[0030] Figure 3A and 3B A perspective view and a side view schematically illustrate the installation of a nozzle guard cap on a jet nozzle. (See diagram.) Figures 3A-3B As shown, a nozzle protective cover 220 is installed on the jet nozzle 210. The jet nozzle 210 includes an inlet 2110 and a first outlet 2120. The water flow that enters the jet nozzle 210 through the inlet 2110 can be ejected through the first outlet 2120.

[0031] As an example, the housing may include a second outlet. For example, such as Figure 6B As shown, a second water outlet 2310 can be provided on the housing 230.

[0032] As an example, the first outlet of the jet nozzle and the second outlet provided on the housing are at least partially connected, so that the water jetted through the first outlet is ejected outward through the second outlet provided on the housing.

[0033] like Figures 3A-3B As shown, a nozzle protective cover 220 is disposed at and detachably connected to the first water outlet 2120. As an example, the nozzle protective cover 220 can change the direction of the water flow ejected from the first water outlet 2120. For instance, when the water flow ejected from the first water outlet is blocked by at least a portion of the nozzle protective cover, its spray direction can be changed, resulting in a more dispersed and uniform spray coverage area.

[0034] Figures 3A-3B Further schematically shown, the nozzle protective cover 220 may include a first end cover 2210 and a second end cover 2220, wherein the second end cover 2220 is sleeved on the outside of the first end cover 2210, and the first end cover 2210 is sleeved at the first outlet 2120.

[0035] As an example, the second end cap 2220 can be fitted onto the first end cap 2210, and the nozzle guard cap 220 can be detachably installed at the outlet 2120 of the jet nozzle 210 via the first end cap 2210.

[0036] As an example, Figure 4A and 4B The perspective view and front view of the first end cap included in the nozzle protective cover are schematically shown respectively. For example... Figures 4A-4B As shown, an annular boss 2230 is provided on the first end cap 2210. By providing an annular boss on the first end cap as a structure for connecting with the second end cap, it is easy to fit the second end cap into the first end cap for detachable connection.

[0037] like Figures 4A-4B As shown, the first end cap 2210 is further provided with a water flow blocking member 2240, which is capable of deforming 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 2240 can be an elastic baffle. For example, 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, the greater the impact force of the water flow, for example, the higher the flow velocity / flow rate of the water flow ejected through the outlet, such as... Figures 4A-4BThe greater the deformation of the water flow obstruction member 2240, the more it flips outwards towards the direction away from the water outlet, thus reducing the obstruction to the water flow ejected from the outlet and allowing it to be sprayed further, forming a larger sprinkler coverage area; conversely, when the impact force of the water flow decreases, such as Figures 4A-4B The deformation of the water flow blocking component 2240 is reduced, and it elastically returns to its original position in the direction closer to the water outlet, which can disperse the water flow ejected from the water outlet, thereby enabling the sprayed water flow to form a close-range sprinkler coverage area.

[0038] like Figures 4A-4B As shown, the upper part of the water flow blocking member 2240 is connected to the upper part of the first end cap 2210 through an arc-shaped connecting part 2260.

[0039] As an example, the water flow blocking component 2240, the first end cap 2210, and the arc-shaped connecting part 2260 can be integrally molded, thereby reducing manufacturing costs and simplifying the installation process.

[0040] like Figure 4B As further shown, the water flow obstruction member 2240 has a shape that is wider at the top and narrower at the bottom when projected from the front along the flow channel axis of the jet nozzle. As an example, Figure 4B The schematic diagram shows the frontal projection of the water flow blocking member 2240 along the axial direction of the jet channel, which presents a triangular shape.

[0041] 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.

[0042] As an example, Figure 5A and 5B The diagrams illustrate the relationship between the two. Figures 4A-4B The first end cap is shown in front and rear views when it is connected to the second end cap.

[0043] like Figure 5A As shown, the second end cap 2220 is provided with an opening 2270 that matches the annular boss, so that the second end cap 2220 can be engaged with the annular boss through the edge of the opening 2270.

[0044] In addition, such as Figure 5B As shown, at least one connector 2296 is provided on the side of the second end cap 2220 facing the first end cap. Furthermore, as... Figures 4A-4B As shown, at least one slot 2250 is provided on the first end cap 2210 to match at least one plug 2296, and the second end cap 2220 and the first end cap 2210 can be fitted together by inserting at least one plug 2296 into at least one slot 2250.

[0045] As described above, the nozzle may include a housing for accommodating at least a portion of the jet nozzle in order to protect the jet nozzle.

[0046] Figure 6A This schematically illustrates a view of the jet nozzle positioned within the housing. (As shown) Figure 6A As shown, a jet nozzle 210 is provided inside the housing 230 and a nozzle protective cover 220 is provided on the housing. For clarity, other components provided inside the housing are omitted.

[0047] As an example, such as Figures 6B-6C As shown, a second water outlet 2310 is provided on the side of the housing 230, and the nozzle protective cover 220 can be placed on the second water outlet 2310 of the housing 230.

[0048] As an example, see Figures 5A-5B At least one snap-fit ​​can be provided on the side of the second outlet 2310 of the second end cap 2220 of the nozzle guard 220 facing the side of the housing 230, for example, Figure 5A The buckle 2280 shown connects the end cap to the housing in a detachable manner using a snap-fit ​​method.

[0049] As an example, the buckle can be a flexible buckle.

[0050] According to embodiments of this disclosure, a locking portion can be provided at the second outlet of the housing for detachable connection with the second end cap of the nozzle protective cover. As an example, Figure 6C The connection between the nozzle guard 220 and the housing 230 is schematically shown.

[0051] like Figure 6C As shown, the engaging portion may include at least one locking plate 2290 disposed on the inner side of the housing 230 near the second water outlet 2310, such that the second end cap 2220 of the nozzle protective cover 220 can be fitted onto the second water outlet 2310 on the housing by engaging with at least one locking plate 2290 disposed on the housing through at least one elastic buckle 2280.

[0052] Furthermore, as an example, such as Figure 5B As shown, a buckle 2292 can also be provided on the side of the second end cap 2220 of the nozzle protective cover 220 facing the second outlet of the housing 230, so that when the end cap 2220 is placed on the second outlet of the housing, as shown... Figures 6B-6CAs shown, the buckle 2292 can engage with the edge 2294 of the second outlet 2310 provided on the housing to increase the connection stability between the end cap 2220 and the housing 230. In this case, the edge 2294 where the second outlet 2310 engages with the buckle 2292 can also be regarded as an engaging part provided on the housing 230 for engaging with the first end cap 2210.

[0053] According to embodiments of this disclosure, a sprinkler irrigation device is also provided, including the above-described sprinkler head.

[0054] According to the sprinkler irrigation apparatus of this disclosure, by providing a nozzle protective cover to the jet nozzle of the sprinkler head, and utilizing the elastic deformation of the water flow blocking member of the nozzle protective cover under the impact force of the jet water, the range of the jet water can be adjusted simply and effectively. For example, when the flow rate of the jet water is higher, its impact force is greater, and the deformation degree of the water flow blocking member is greater, causing it to flip 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 water flow rate decreases, its impact force decreases, the deformation degree of the water flow blocking member decreases, and it elastically returns to its original position in the direction closer to the outlet, thereby effectively dispersing the jet water at close range, so that the jet water can form a close-range sprinkler coverage area.

[0055] For example, with a maximum jet flow rate of approximately 20 L / min, the jet flow rate can be adjusted from a distance of 1 meter to a maximum range of 14 meters when the jet flow rate changes. This can significantly improve the uniformity of the spray coverage without affecting the maximum range.

[0056] In addition, the nozzle protective cover is designed to be detachable, which facilitates its installation, maintenance and replacement.

[0057] 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. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0058] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
