Description

Technical Field

[0001] This invention relates to the field of irrigation equipment technology, and more particularly to a sprinkler head and irrigation equipment with a quick-release nozzle. Background Technology

[0002] In sprinkler irrigation systems, water is typically sprayed through nozzles. These nozzles are generally fixed in design, making disassembly inconvenient once installed. During use, nozzles are susceptible to clogging due to mud and impurities. Existing nozzle designs often hinder user disassembly and cleaning, requiring specialized equipment and tools, thus impacting the efficiency of routine maintenance. Once a nozzle becomes clogged, it can disrupt the normal operation of the entire irrigation system.

[0003] Different crops and growth stages have different requirements for the strength of sprinkler heads and nozzles. The replacement process of existing nozzles is complicated and difficult to quickly adapt to diverse irrigation needs.

[0004] Currently, nozzles are typically installed in the main body in a removable manner for easy replacement when changes in spray intensity and range are needed. However, disassembly is required for replacement, and each replacement process is time-consuming. In large-area irrigation areas, frequent nozzle replacements are not only time-consuming and labor-intensive but also increase operating costs.

[0005] In related technologies, some nozzles are designed to be detachable, but their assembly and disassembly structures are still relatively complex, making it difficult to replace the nozzles quickly and conveniently. Summary of the Invention

[0006] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a nozzle with a quick-release nozzle, designed to achieve rapid installation, removal, and replacement of the nozzle.

[0007] The present invention also proposes an irrigation device.

[0008] According to a first aspect embodiment of the present invention, a nozzle having a quick-release nozzle includes:

[0009] Lower diffuser;

[0010] The upper supply section includes a main body and a supporting component. The main body is connected to the lower diffusion section through the supporting component. A diffusion space is formed between the main body and the lower diffusion section. The main body has an installation space with a side wall opening and a jet outlet at the bottom of the main body to connect the installation space and the diffusion space.

[0011] The nozzle includes a body, an actuating part, and a supporting part. The supporting part abuts against the inner wall of the installation space. The body is mounted on the supporting part and has a water outlet corresponding to the jet outlet. The actuating part is connected to the supporting part and is located outside the installation space and engaged with the body. The actuating part is adapted to deform under external force to disengage from the engaged position with the body. The nozzle is adapted to spray water onto the lower diffuser so that the lower diffuser can diffuse the water flow using the diffusion space.

[0012] According to an embodiment of the present invention, a nozzle with a quick-release nozzle is connected to an upper supply section and a lower diffuser section. Specifically, the main body is supported on the lower diffuser section by a support member, thereby forming a diffused space that spreads outwards. When water is sprayed toward the lower diffuser section, the water flow spreads out from the diffused space to achieve an irrigation effect. The main body has an installation space with a side wall opening, allowing the nozzle to be installed into the installation space through the side wall of the main body, which is convenient and quick. The support section and the actuator section of the nozzle are used to snap and fix it onto the main body, so that the outlet of the main body corresponds to the jet outlet. At the same time, at least a portion of the actuator section is located outside the installation space, allowing the user to directly manipulate the actuator section to deform relative to the support section, thereby disengaging the actuator section from the snap-fit ​​position with the main body and easily removing the nozzle. Thus, when installing the nozzle, it is simply pushed from the side wall of the main body into the installation space to the snap-fit ​​position; when removing the nozzle, it is simply manipulated from outside the installation space to disengage it from the snap-fit ​​position, thereby achieving quick and convenient installation and removal of the nozzle.

[0013] According to one embodiment of the present invention, the actuating part includes an actuating handle and a connecting section. One end of the connecting section is connected to the support part, and the other end is connected to the actuating handle. The actuating handle is provided with one of a fixing groove and a fixing protrusion. The main body is provided with the other of the fixing groove and the fixing protrusion on one side of the installation space opening. The fixing protrusion engages with the fixing groove. The actuating handle is adapted to deform the connecting section under the action of external force so that the fixing protrusion disengages from the fixing groove.

[0014] According to one embodiment of the present invention, the connecting segment is a downwardly curved arc segment.

[0015] According to one embodiment of the present invention, the support portion includes a movable column and a connecting column, the main body portion is installed between the movable column and the connecting column, one end of the arc-shaped segment is connected to the connecting column, and the movable column supports and abuts against the inner wall of the installation space.

[0016] According to one embodiment of the present invention, the installation space is provided with a first arc-shaped slide and a second arc-shaped slide arranged opposite to each other. Both the first arc-shaped slide and the second arc-shaped slide extend arc-shapedly from the bottom to the top of the installation space. The top of the first arc-shaped slide is provided with a first bearing groove, and the top of the second arc-shaped slide is provided with a second bearing groove. One end of the circular moving column is supported and abuts against the first bearing groove, and the other end is supported and abuts against the second bearing groove.

[0018] The hollow section has the installation space and the hollow section has the jet outlet;

[0019] The tubular part is connected to the hollow part, and the tubular part is provided with a water supply channel, which is connected to the nozzle.

[0020] According to one embodiment of the present invention, the main body further includes a flow stabilizer pipe and a sealing ring, the flow stabilizer pipe being disposed within the water supply channel, and the sealing ring being disposed between the flow stabilizer pipe and the nozzle.

[0021] According to one embodiment of the present invention, the lower diffuser includes a housing, a fixed base, a base, and a water distribution plate. The housing has a mounting cavity communicating with the top. The fixed base is disposed in the mounting cavity. One end of the base abuts against the fixed base, and the other end of the base extends toward the opening of the mounting cavity. The water distribution plate is connected to the end of the base away from the fixed base. The base is rotatable relative to the fixed base. Both the base and the water distribution plate have an installation gap with respect to the housing. The base is adapted to swing relative to the housing with the fixed base as a fulcrum.

[0022] According to one embodiment of the present invention, the fixing seat has an arc-shaped protrusion on the side facing the base, and the bottom of the base has an arc-shaped groove, the groove wall of the arc-shaped groove abutting against the arc-shaped protrusion, so that the base swings with the fixing seat as the fulcrum.

[0023] An irrigation apparatus according to a second aspect of the present invention includes a water supply device and a nozzle having a quick-release nozzle, wherein the water supply device is in communication with a nozzle of the nozzle having a quick-release nozzle, and the water supply device supplies water to the nozzle having a quick-release nozzle.

[0024] The irrigation device according to an embodiment of the present invention includes the above-described nozzle with a quick-release nozzle, and therefore has all the technical effects of the above-described nozzle with a quick-release nozzle, which will not be repeated here.

[0055] The following is based on Figures 1 to 21 This invention introduces a nozzle with a quick-release nozzle. According to a first aspect embodiment of the invention, the nozzle with a quick-release nozzle includes a lower diffuser, an upper supply section, and a nozzle 8. The upper supply section includes a main body 6 and a support member 7. The main body 6 is connected to the lower diffuser via the support member 7. A diffusion space 5 is formed between the main body 6 and the lower diffuser. The main body 6 has an installation space 611 with a side wall opening, and a jet outlet 612 is provided at the bottom of the main body 6 to connect the installation space 611 and the diffusion space 5. The nozzle 8 includes... The device comprises a body 81, an actuator 82, and a support 83. The support 83 abuts against the inner wall of the installation space 611. The body 81 is mounted on the support 83 and has a water outlet corresponding to the jet outlet 612. The actuator 82 is connected to the support 83 and is located outside the installation space 611 and engaged with the body 6. The actuator 82 is adapted to deform under external force to disengage from the engaged position with the body 6. The nozzle 8 is adapted to spray water into the downward diffuser so that the downward diffuser can diffuse the water flow using the diffusion space 5.

[0056] like Figure 11As shown, the nozzle with a quick-release nozzle according to an embodiment of the present invention is connected to the lower diffuser via an upper supply section. Specifically, the main body 6 is supported on the lower diffuser via a support member 83 7, thereby forming a diffuser space 5 that diffuses in all directions. When water is sprayed toward the lower diffuser, the water flow spreads out from the diffuser space 5 to achieve an irrigation effect. The main body 6 is provided with an installation space 611 with a side wall opening. The nozzle 8 can be installed into the installation space 611 through the side wall of the main body 6, which is convenient and quick. The support member 83 and the actuator 82 of the nozzle 8 are used to snap and fix it to the main body 6, so that the water outlet of the main body 81 corresponds to the jet outlet 612. At the same time, at least a part of the actuator 82 is located outside the installation space 611. The user can directly move the actuator 82 to deform the actuator 82 relative to the support member 83, thereby disengaging the actuator 82 from the snap-fit ​​position with the main body 6, and the nozzle 8 can be easily removed. Thus, when installing the nozzle 8, it can be done by pushing the nozzle 8 from the side wall of the main body 6 into the mounting space 611 to the snap-fit ​​position. When removing the nozzle 8, it can be removed by moving the actuator 82 out of the mounting space 611 to disengage it from the snap-fit ​​position. This allows for quick and easy installation and removal of the nozzle 8.

[0057] Understandably, the nozzle 8 is adapted to be inserted radially toward the body 6, passing through the side-opening mounting space 611, and positioned substantially coaxially with the body 6 within the mounting space 611, thereby guiding the liquid jet axially downwards. Optionally, the body portion 81 of the nozzle 8 has a tapered structure, wider at the top and narrower at the bottom, thus converging the water flow for spraying onto the lower diffuser. The side opening of the body 6 always provides a passage to the mounting space 611 for mounting the nozzle 8. The side opening of the mounting space 611 is not opposite to the jet direction, facilitating the insertion and removal of the nozzle 8. This specific structure allows the nozzle 8 to be quickly inserted or removed from the body 6 without stopping the system water supply, which can pass through the mounting space 611 and be ejected from the jet outlet 612. The nozzle 8 features good stability, high efficiency, and relatively low cost, and its simple structure allows it to be stably and securely fixed to the body 6, always ensuring a good sealing effect.

[0058] In one embodiment, the support 83 7 consists of two support arms, which are respectively connected to both sides of the main body 6 and connected to the lower diffuser to support the main body 6, forming a diffusion space 5 to facilitate the outward diffusion of water flow. The outlet of the nozzle 8 is positioned facing the lower diffuser, which may be equipped with a rotating disk 44 or outwardly radiating water channels to diffuse the sprayed water. This nozzle with a quick-release nozzle is designed to distribute irrigation liquid, typically water, onto the soil to be irrigated.

[0059] Please refer to the reference. Figures 1 to 5According to one embodiment of the present invention, the actuating part 82 includes an actuating handle 821 and a connecting section 822. One end of the connecting section 822 is connected to the support part 83, and the other end is connected to the actuating handle 821. The actuating handle 821 is provided with one of a fixing groove 8211 and a fixing protrusion 613. The main body 6 is provided with the other of the fixing groove 8211 and the fixing protrusion 613 on one side of the opening of the installation space 611. The fixing protrusion 613 engages with the fixing groove 8211. The actuating handle 821 is adapted to deform the arc segment under the action of external force so that the fixing protrusion 613 disengages from the fixing groove 8211.

[0060] In other words, the actuation handle 821 can be configured with a fixing slot 8211, and the main body 6 can be configured with a fixing protrusion 613, so that the two are locked together. Of course, the actuation handle 821 can also be configured with a fixing protrusion 613, and the main body 6 can be configured with a fixing slot 8211; this is not limited here. Taking the actuation handle 821 with a fixing slot 8211 as an example, the main body 6 is provided with a fixing protrusion 613, which is a fixing protrusion 613 that engages with the fixing slot 8211 to fix the nozzle 8.

[0061] Understandably, the actuation handle 821 has an upper surface and a side surface facing the main body 6. A fixing groove 8211 is provided on the side surface, so that the fixing groove 8211 can face the fixing protrusion 613 on the main body 6, which facilitates the fixing of the nozzle 8. When the actuation handle 821 is pulled back to an appropriate position, the nozzle 8 can be stably removed from the main body 6.

[0062] Please refer to the reference. Figures 6 to 8 In the preferred embodiment shown, such as Figure 6 As shown, the nozzle 8 is inserted into the mounting space 611 in a radial direction at an angle downwards. After the nozzle 8 is fully inserted into the mounting position, the actuation handle 821 is pulled in a basically vertical direction to engage with the fixing protrusion 613, thereby enabling the nozzle 8 to reach the designated position.

[0063] In one embodiment not shown, with Figure 6 The difference is that the nozzle 8 is inserted radially from the lower side into the installation space 611 from the upper side. First, a portion of the nozzle 8 is inserted, and then the actuation handle 821 can be engaged with the fixing protrusion 613 on the main body 6 through the fixing slot 8211. Finally, the nozzle 8 is pushed into the installation space 611, and the same effect can be achieved at the same time.

[0064] like Figure 5 As shown, in one embodiment, the outer surface of the actuated handle 821 is provided with anti-slip texture or hand groove to facilitate the user's gripping and prevent slippage.

[0065] like Figure 4As shown, according to one embodiment of the present invention, the connecting segment 822 is a downwardly curved arc segment.

[0066] Understandably, to facilitate the deformation of the actuating part 82 to disengage from the snap-fit ​​position, the actuating handle 821 is connected to the support part 83 via a connecting section 822. The connecting section 822 is bent downwards into an arc shape, giving it a slightly flexible physical property. This allows the fixing groove 451 on the actuating handle 821 to engage with the fixing protrusion 613 without removing the nozzle 8, and also facilitates removal of the actuating handle 821 from the fixing protrusion 613 by turning it. In this case, the nozzle 8 can be easily removed by first turning the actuating handle 821 in the opposite direction of insertion and then removing it, making the operation simple.

[0067] like Figure 5 As shown, according to an embodiment of the present invention, the support portion 83 includes a circular movable column 831 and a connecting column 832, the body portion 81 is installed between the circular movable column 831 and the connecting column 832, one end of the arc-shaped segment is connected to the connecting column 832, and the circular movable column 831 supports and abuts against the inner wall of the installation space 611.

[0068] Understandably, the support part 83 can be a plate-like structure with a through hole in the middle for mounting the main body part 81, i.e., the main body part 81 passes through the through hole to spray water toward the jet outlet 612. The circular moving column 831 and the connecting column 832 are provided on both sides of the main body part 81 to connect and support the main body part 81.

[0069] Preferably, the support portion 83 can be integrally formed with the body portion 81 to form a single component, and the support portion 83, the body portion 81, and the actuating portion 82 can be integrally formed to form a single component, thereby always ensuring that the nozzle 8 is correctly inserted and in a centered position. In addition, after the circular moving column 831 on the support portion 83 enters the installation space 611, the circular moving column 831 can overlap the supporting component in the installation space 611, so that it cooperates and abuts against the upper edge of the installation space 611, thereby keeping the circular moving column 831 in a state where it can only rotate at a small angle.

[0070] It should be noted that the actuation handle 821 is suitable for being actuated by the user to promote the rotation of the nozzle 8 around the central axis of the circular moving column 831, so that the fixing slot 8211 engages or disengages from the fixing protrusion 613.

[0071] like Figure 9 and Figure 10As shown, according to an embodiment of the present invention, the installation space 611 is provided with a first arc-shaped slide rail 6111 and a second arc-shaped slide rail 6112 arranged opposite to each other. The first arc-shaped slide rail 6111 and the second arc-shaped slide rail 6112 both extend arc-shapedly from the bottom to the top of the installation space 611. The top of the first arc-shaped slide rail 6111 is provided with a first bearing groove 6113, and the top of the second arc-shaped slide rail 6112 is provided with a second bearing groove 6115. One end of the circular moving column 831 is supported and abuts against the first bearing groove 6113, and the other end is supported and abuts against the second bearing groove 6115.

[0072] Specifically, the interior of the main body 6 is an installation space 611. Within the installation space 611, on both sides, are a first vertical surface and a second vertical surface that roughly position the insertion point of the nozzle 8. That is, the first vertical surface and the second vertical surface are parallel, and the first and second vertical surfaces can clamp the nozzle 8 in the middle. Furthermore, connected to the substantially vertical first and second vertical surfaces are a first arc-shaped slide rail 6111 and a second arc-shaped slide rail 6112. The top of the installation space 611 has an upper edge, a first bearing groove 6113, a second bearing groove 6115, and the upper edge together constrain the circular moving column 831 of the support part 83. It can be understood that these two arc-shaped slide rails are designed to slide against the sliding surface on the support part 83, so that when the nozzle 8 begins to be inserted into the installation space 611, it facilitates the translation of the nozzle 8, preparing for the subsequent locking of the nozzle 8 into place.

[0073] In one embodiment, the surface of the circular movable column 831 is a sliding surface, which adheres closely to the first arc-shaped slide rail 6111 and the second arc-shaped slide rail 6112 to facilitate smooth entry into the installation space 611, making installation more convenient. It is understood that the support portion 83, carrying the main body portion 81, allows insertion into and removal from the installation space 611 without requiring the water supply component to be removed from the downlink supply line.

[0074] For example, such as Figures 7 to 8 As shown, the support part 83 moves from the second position to the third position and is fixed on the main body 6 at the third position. After the actuation handle 821 is applied, it is pressed against the installation space 611 to achieve a sealing effect.

[0075] It should be noted that the two ends of the circular moving column 831 are normally constrained by the side wall of the installation space 611, so that the nozzle 8 can slide smoothly on the first arc-shaped slide 6111 and the second arc-shaped slide 6112 to achieve the centered positioning of the nozzle 8.

[0076] The support part 83 is designed to allow the circular movable column 831 to slide upward to the end on the first arc-shaped slide 6111 and the second arc-shaped slide 6112, so that the nozzle 8 can be inserted at any position of the slide, and the axial translation of the nozzle 8 can be guaranteed to ensure that it is installed in place, so that the nozzle 8 can be connected to the water supply port.

[0077] Optionally, the support portion 83 is also designed to allow the movable column 831 to rotate axially along the movable column 831 between the ends of the first arc-shaped slide rail 6111 and the second arc-shaped slide rail 6112, the first bearing groove 6113 and the second bearing groove 6115 and the upper edge of the mounting space 611, so as to facilitate the engagement of the actuation handle 821 with the fixing protrusion 613.

[0078] Furthermore, after the circular moving column 831 contacts the first arc-shaped slide rail 6111 and the second arc-shaped slide rail 6112 and begins to slide, the lower surface of the support part 83 can also slide on the first arc-shaped slide rail 6111 and the second arc-shaped slide rail 6112. This phenomenon only stops after the actuation handle 821 is pulled in a basically vertical direction.

[0079] It should be noted that the opening width of the installation space 611 is just enough to allow the circular moving post 831 on the support part 83 to be inserted, so as to ensure the accurate centering of the nozzle 8, thereby preventing the nozzle 8 from shifting its position when the actuation handle 821 is pulled upward.

[0080] In another embodiment not shown, the outer wall thickness of the nozzle 8 can be widened until it fits the first vertical plane and the second vertical plane on both sides of the mounting space 611, thereby ensuring the accurate centering of the nozzle 8.

[0081] like Figure 1 As shown, according to an embodiment of the present invention, the main body 6 includes a hollow part 61 and a tubular part 62. The hollow part 61 is provided with an installation space 611 and a jet outlet 612. The tubular part 62 is connected to the hollow part 61 and is provided with a water supply channel 621, which is connected to the nozzle 8.

[0082] Understandably, the tubular part 62 has an irrigation water inlet at the top of the water supply channel 621 and an outlet at the bottom that communicates with the installation space 611. The circumference of the tubular part 62 is a threaded interface for connecting to an external irrigation water pipe. The bottom of the tubular part 62 is a hollow part 61 for installing the nozzle 8.

[0083] Specifically, the upper edge of the nozzle 8 is tightly fixed to the outlet of the tubular portion 62 in a substantially coaxial and facing relationship through the cooperation of the actuating part 82 and the supporting part 83. The nozzle 8 is installed in the mounting space 611 and is detachably connected to the outlet of the tubular portion 62, thereby guiding the liquid jet downward to the lower diffuser. The mounting space 611 is conveniently located downstream of the outlet of the tubular portion 62 and is designed to allow the nozzle 8 to enter the mounting space 611 at least in the oblique radial direction.

[0084] For example, the support portion 83 and the actuating portion 82 fix the body portion 81 so that it abuts against the outlet of the water supply channel 621 to ensure a proper sealing effect, thus allowing for the option of not performing a seal. The body portion 81 of the nozzle 8 has a flared upper edge, and the tubular portion 62 has a fitted outlet whose shape matches the shape of the upper edge so that the two seal against each other when the actuating handle 821 is lifted, thereby achieving a sealing effect even when no seal is provided.

[0085] like Figure 6 As shown, according to one embodiment of the present invention, the main body 6 further includes a flow stabilizing pipe 63 and a sealing ring 64. The flow stabilizing pipe 63 is disposed within the water supply channel 621, and the sealing ring 64 is disposed between the flow stabilizing pipe 63 and the nozzle 8. It is understood that the tubular portion 62 is used to connect to an external water supply pipe, and the water flow from the water supply pipe may be somewhat turbulent. Therefore, by installing a flow stabilizing pipe 63 within the water supply channel 621 of the tubular portion 62, it is helpful to stabilize the water flow and make the water flow more uniform. Simultaneously, a sealing ring 64 can be sandwiched between the flow stabilizing pipe 63 and the nozzle 8 to prevent water from seeping into the surrounding area.

[0086] Optionally, in the irrigation system, the threaded interface of the tubular portion 62 of each nozzle 8 is connected to a descending supply line for distributing the irrigation jet substantially uniformly on the surface to be irrigated.

[0087] In other embodiments, the flow stabilizer 63 is closely attached to the inner wall of the water supply channel 621 of the tubular portion 62. A tapering opening is provided at the bottom of the flow stabilizer 63. The tapering opening gradually narrows in the direction away from the flow stabilizer 63 so that it fits tightly with the upper edge of the nozzle 8 to achieve a sealing effect. In this way, the sealing ring 64 can be omitted, saving installation costs.

[0088] Please refer to the reference. Figure 11 and Figure 12 According to one embodiment of the present invention, the lower diffuser includes a housing 1, a fixed base 2, a base 3, and a water distribution plate 4. The housing 1 has an installation cavity 11 communicating with the top. The fixed base 2 is disposed in the installation cavity 11. One end of the base 3 abuts against the fixed base 2, and the other end of the base 3 extends toward the opening of the installation cavity 11. The water distribution plate 4 is connected to the end of the base 3 away from the fixed base 2. The base 3 can rotate relative to the fixed base 2. Both the base 3 and the water distribution plate 4 have an installation gap with the housing 1. The base 3 is adapted to swing relative to the housing 1 with the fixed base 2 as the fulcrum.

[0089] In this embodiment, the lower diffuser is designed to disperse the water flow, and the water distribution plate 4 distributes the jet in a deflecting and radial manner. The water distribution plate 4 can be stationary or can be rotated by mounting on a support shaft, allowing the water distribution plate 4 to rotate with complex motions, which are either rotations of the water distribution plate 4 about its own axis or oscillations based on the rotation of the water distribution plate 4, thereby providing a wider radial range and more uniform liquid distribution.

[0090] The main body 6 is connected to the housing 1 via the support part 83 7. A diffusion space 5 is formed between the main body 6 and the housing 1. The nozzle 8 is located on the main body 6, and the outlet of the nozzle 8 is set towards the water distribution plate 4.

[0091] According to an embodiment of the present invention, a nozzle with a quick-release nozzle forms a diffusion space 5 between a lower diffuser and an upper supply section. The upper supply section guides the water flow to supply water, and when water is sprayed toward the lower diffuser, the water distribution plate 4 distributes the jet in a deflected and radial manner to achieve irrigation. The housing 1 of the lower diffuser has a mounting cavity 11 for mounting a fixed base 2 and restricting the swing of the base 3. The base 3 is supported on the fixed base 2 to achieve swinging, so that the water distribution plate 4, located above the base 3, can rotate relative to the base 3 to achieve a rotating water distribution effect, resulting in more uniform irrigation. The water distribution plate 4 is located above the housing 1, and water is ejected toward the water distribution plate 4 from the nozzle 8 of the upper supply section. The water distribution plate 4 rotates under the impact of the water flow. Simultaneously, with the impact of the water flow, the base 3 can also swing relative to the housing 1, and the water distribution plate 4 swings under the drive of the base 3, thereby achieving more uniform irrigation over a wider area. The nozzle 8 is located above the water distribution plate 4. The impact force of the water jet and its own gravity can drive the water distribution plate 4 to rotate, improving energy utilization. Thus, with the swing of the base 3 and the rotation of the water distribution plate 4, the irrigation range of the sprinkler head is wider and the irrigation area is more uniform.

[0092] like Figure 13As shown, in one embodiment, the water distribution plate 4 includes a rotating plate 44 and a connecting shaft 43. The rotating plate 44 is connected to the base 3 through the connecting shaft 43, so that the rotating plate 44 can rotate relative to the base 3. The upper part of the rotating plate 44 has multiple flow channels, that is, multiple flow channels are provided on the side of the rotating plate 44 facing the nozzle 8. Each flow channel can be composed of a deflection flow channel 411, a direct flow channel 412 and a flow channel outlet 413. The bottom of the water distribution plate 4 is a support platform 42, which is attached to the base 3. The bottom of the water distribution plate 4 is provided with a first constraint shaft 45, which is used to connect with the base 3. Specifically, a second constraint shaft 31 can be provided at one end of the base 3. The first constraint shaft 45 and the second constraint shaft 31 are nested together to prevent radial displacement. Furthermore, the inner wall of the first restraint shaft 45 is provided with a fixing groove 451, and the outer wall of the second restraint shaft 31 is provided with a fixing protrusion 311. When the second restraint shaft 31 is fitted inside the first restraint shaft 45, the fixing protrusion 311 and the fixing groove 451 are engaged together to prevent the first restraint shaft 45 and the second restraint shaft 31 from undergoing normal displacement.

[0093] Please refer to the reference. Figures 14 to 18 The base 3 includes a second constraint shaft 31, a rotating shaft 32, and a contact platform 33 connected in sequence. The outer wall of the second constraint shaft 31 has a fixing protrusion 311, and the inner cavity of the second constraint shaft 31 has a flat surface with a small hole 312 for drainage. It is understood that the connecting shaft 43 can pass through the inner cavity of the second constraint shaft 31 to utilize the installation space 611. If water enters the inner cavity of the second constraint shaft 31, it can be drained through the small hole 312 to prevent water accumulation and obstruction of the water distribution plate 4. The contact platform 33 is a tapered connecting column 832, and the bottom of the contact platform 33 abuts against the fixed base 2 to allow the base 3 to swing.

[0094] Understandably, the bottom of the water distribution plate 4 is a support platform 42, which is connected to the base 3. The bottom of the water distribution plate 4 is surrounded by a first constraint shaft 45, which surrounds the support platform 42. The first constraint shaft 45 is fitted onto the second constraint shaft 31 to prevent radial displacement.

[0095] Please refer to the reference. Figure 16 and Figure 19 According to one embodiment of the present invention, the fixed seat 2 is provided with an arc-shaped protrusion 21 on the side facing the base 3, and the bottom of the base 3 is provided with an arc-shaped groove 331. The groove wall of the arc-shaped groove 331 abuts against the arc-shaped protrusion 21 so that the base 3 swings with the fixed seat 2 as the fulcrum.

[0096] In this embodiment, specifically, the arc-shaped protrusion 21 is surrounded by connecting plates 22, and the arc-shaped protrusion 21 is connected to the base 23 through the connecting plates 22. The base 23 is fixed to the housing 1 and located at the bottom of the mounting cavity 11. The fixed base 2 is fixedly connected to the inner wall of the mounting cavity 11 around its perimeter. The fixed base 2 has an arc-shaped protrusion 21 at its center, which can be hemispherical, to support the base 3 and allow the base 3 to swing relative to the fixed base 2. The base 3 swings with the fixed base 2 as the fulcrum. When the water distribution plate 4 is impacted by water flow, the base 3 can rotate and swing relative to the fixed base 2, which can effectively improve the uniformity of irrigation. That is, as the base 3 rotates and swings, the water distribution plate 4 rotates on its own axis and is driven by the base 3 to revolve around the central axis of the housing 1. The combination of the rotation and revolution of the water distribution plate 4 effectively improves the uniformity of irrigation. It should be noted that the base 3 can drive the water distribution plate 4 to revolve at a certain angle along the vertical central axis of the casing, but it is not limited to revolving motion; it can also be other forms of motion such as swinging left and right or swinging back and forth.

[0097] Understandably, the arc-shaped protrusion 21 and the arc-shaped groove 331 are adapted to each other. When the base 3 swings, the inner wall of the arc-shaped groove 331 slides relative to the surface of the arc-shaped protrusion 21. To reduce friction, the surface of the arc-shaped protrusion 21 is a smooth surface, or lubricating oil is applied between the arc-shaped protrusion 21 and the inner wall of the arc-shaped groove 331. This ensures that the base 3 can support the water distribution plate 4 and rotate and swing together on the fixed base 2. Optionally, the groove wall of the arc-shaped groove 331 is provided with a cylindrical hole 332, which can accommodate a certain amount of air, thereby balancing the internal and external pressures and preventing the arc-shaped protrusion 21 and the arc-shaped groove 331 from fitting too tightly, resulting in a pressure difference between the inside and outside that prevents the base 3 from swinging.

[0098] like Figure 12 As shown, according to an embodiment of the present invention, the lower diffuser further includes a limiting member 12, which is disposed on the inner wall of the mounting cavity 11. The limiting member 12 is arranged around the periphery of one end of the base 3 adjacent to the fixed seat 2, and there is a gap between the limiting member 12 and the one end of the base 3 adjacent to the fixed seat 2. The limiting member 12 is used to limit the swing angle of the base 3.

[0099] Please refer to the reference. Figure 12 , Figure 20 and Figure 21Understandably, the base 3 requires a relatively large installation space 611 because its upper part is used to support the water distribution plate 4, while its lower part is used for swinging. Furthermore, when the base 3 rotates and swings, it swings in a conical angle around the fixed base 2, thus requiring a smaller installation space 611 below. The mounting cavity 11 is cylindrical, and the upper part of the base 3 can be stopped and limited by the inner wall of the mounting cavity 11. To prevent excessive displacement at the lower fulcrum of the base 3, a limiting member 12 is used for stopping and limiting. Optionally, the limiting member 12 is connected to the inner wall of the mounting cavity 11 and is arranged around the end of the base 3 adjacent to the fixed base 2. The limiting member 12 is spaced a certain distance from the base 3 to limit the swing angle of the base 3 and prevent the base 3 from detaching from the fixed base 2.

[0100] Understandably, the top of the housing 1 is used to support the pivot guardrail 14, which can be used to stop and limit the swing angle of the base 3. For example, the pivot guardrail 14 allows the base 3 to have a maximum deflection radius of R at this location.

[0101] According to one embodiment of the present invention, the lower diffuser further includes a weighting device 13, which is installed inside the housing 1.

[0102] The housing 1 has a hollow cylindrical inner cavity, in which the weight booster 13 is fitted. The inner cavity is used to constrain the movement of the weight booster 13. The weight booster 13 is used to increase the stability of the nozzle when it swings. Under the gravity of the weight booster 13, the lower diffuser can be guaranteed to operate stably during the diffusion process, reducing large swings.

[0103] like Figure 17 As shown, according to an embodiment of the present invention, the top surface of the water distribution plate 4 is an arc-shaped structure that is concave from the center to the periphery. The top surface of the water distribution plate 4 is provided with a plurality of water distribution channels 41. The plurality of water distribution channels 41 are arranged at intervals along the periphery of the water distribution plate 4, and the water distribution channels 41 extend from the center of the water distribution plate 4 to the periphery.

[0104] For example, multiple water distribution channels 41 radiate outwards from the center of the water distribution plate 4. Understandably, these multiple channels help to converge and disperse the water flow, improving sprinkler irrigation efficiency. The jet from the nozzle 8 impacts the water distribution channels 41 of the water distribution plate 4, causing the plate to rotate under the impact force. Furthermore, the base 3 revolves relative to the fixed base 2. Subsequently, the water flows out from the outlet 413 of the rotating and revolving water distribution plate 47, achieving more uniform irrigation over a wider area. In particular, it meets the requirement of large-area uniformity while also enabling normal irrigation in sloping irrigation areas.

[0105] According to one embodiment of the present invention, each water distribution channel 41 includes a deflection channel 411, a direct flow channel 412, and a channel outlet 413. One end of the deflection channel 411 is adjacent to the center of the water distribution plate 4. The deflection channel 411 includes a first sidewall and a second sidewall arranged opposite to each other. The first sidewall and the second sidewall gradually move away from each other in a direction away from the center of the water distribution plate 4. One end of the direct flow channel 412 is connected to the deflection channel 411. The direct flow channel 412 includes a third sidewall and a fourth sidewall arranged opposite to each other. The third sidewall transitions smoothly to the first sidewall, and the fourth sidewall transitions arcuately to the second sidewall. The channel outlet 413 is located at the outer periphery of the water distribution plate 4 and is connected to the direct flow channel 412.

[0106] Specifically, the water distribution plate 4 has a connecting shaft 43 in the middle, and a rotating plate 44 around the connecting shaft 43. The upper part of the rotating plate 44 has multiple flow channels, which can effectively and evenly spread the water flow on the water distribution plate 4 over a large area. The straight channel 412 is basically arranged in a straight line to spread the water flow outward.

[0107] It should be noted that when the jet ejected from the nozzle 8 impacts the water distribution plate 4, the jet flows into the water distribution channel 41 to form a water flow. When the water flow passes through the deflection channel 411, it exerts a force perpendicular to the deflection channel 411 on the water distribution plate 4. Under the continuous action of this force, the water distribution plate 4 will rotate. Specifically, the first and second sidewalls of each pair of adjacent deflection channels 411 are close to each other, and the water flow continuously impacts multiple deflection channels 411 at one angle, thereby facilitating the rotation of the water distribution plate 4.

[0108] Furthermore, since the initial position of the water distribution plate 4 is not vertical when the jet impacts it (i.e., the water distribution plate 4 is connected to the base 3, and the base 3 initially swings at a certain angle relative to the casing 1 and leans against the casing 1), the position where the jet hits the water distribution plate 4 is not the center position of the water distribution plate 4. Thus, under the impact of the water flow, the base 3 rotates and swings, causing the water distribution plate 4 to rotate on its own axis while simultaneously forming a oscillating revolution. Specifically, when the water distribution plate 4 and the base 3 revolve on the fixed base 2, their central axis forms a deflection angle θ with the central axis of the casing 1.

[0109] like Figure 17 As shown, according to one embodiment of the present invention, the central axis of the direct current channel 412 is offset from the center of the water distribution plate 4 at a certain angle. That is, the direct current channel 412 extends in a straight line without passing through the center of the water distribution plate 4. When the water distribution plate 4 is impacted by water flow, the water flow flows along the direct current channel 412, which is beneficial for the water flow to better drive the water distribution plate 4 to rotate.

[0110] In one embodiment, a stop protrusion 4121 is provided on one side of the direct current channel 412. The stop protrusion 4121 is perpendicular to the upper surface of the water distribution plate 4. The stop protrusion 4121 can stop a portion of the water sprayed from the nozzle 8 onto the water distribution plate 4, and is used to drive the water distribution plate 4 to rotate. This allows for better utilization of the impact force of the water flow and conversion of it into the rotational force of the water distribution plate 4.

[0111] An irrigation apparatus according to a second aspect of the present invention includes a water supply device and a sprinkler head having a quick-release nozzle, wherein the water supply device is in communication with a nozzle 8 of the sprinkler head having a quick-release nozzle, and the water supply device supplies water to the sprinkler head having a quick-release nozzle. Optionally, the sprinkler head having a quick-release nozzle can be applied to a center-pivot sprinkler irrigation machine.

[0112] The irrigation device according to an embodiment of the present invention includes the above-described nozzle with a quick-release nozzle, and therefore has all the technical effects of the above-described nozzle with a quick-release nozzle, which will not be repeated here.

[0113] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
