Description

Technical Field

[0001] This application relates to the field of garden irrigation technology, and in particular to an irrigation device. Background Technology

[0002] Garden and agricultural irrigation is a technical means of providing water to plant roots or leaves through artificial intervention. It is a core element in ensuring plant growth, with the core objective of achieving efficient water resource utilization while ensuring healthy plant growth through scientific regulation of water supply. Globally, approximately 70% of freshwater consumption originates from agricultural irrigation (data from the Food and Agriculture Organization of the United Nations). Traditional irrigation systems heavily rely on municipal water supply networks, with water consumption per unit area reaching 10-15 cubic meters per acre per irrigation, exacerbating groundwater over-extraction and ecological degradation in water-scarce regions. Simultaneously, rainwater harvesting devices often employ static planar flow-guiding structures (such as funnel-type collectors), which, limited by fluid dynamics design flaws, generally have low rainwater harvesting efficiency and are prone to pipe blockage due to sediment and debris accumulation, resulting in high maintenance costs.

[0003] Traditional irrigation systems have the following drawbacks:

[0004] (1) The irrigation device and the rainwater harvesting module operate independently, which cannot form a closed loop of water resources of "collection-filtration-reuse", and the dependence on municipal water supply is high.

[0005] (2) The irrigation device lacks a filtration structure, which easily leads to blockage of the rainwater collection pipes and high maintenance costs in the later stage.

[0006] (3) The irrigation mode of the irrigation device is monotonous, which easily leads to the waste of water resources.

[0007] In summary, existing irrigation devices suffer from drawbacks such as low utilization of rainwater, high clogging rate, and limited functionality, leading to water waste. Utility Model Content

[0008] The irrigation device provided in this application solves the problems of low water resource utilization and high clogging rate in existing irrigation devices.

[0009] This application provides an irrigation device, including: a water storage container, an irrigation assembly, and a switching assembly. The water storage container has a water storage cavity formed around it, and the top of the water storage container has an opening to allow the water storage cavity to communicate with the external space of the water storage container. The irrigation assembly includes a water pump, a pipeline, and a nozzle, with the water pump connected to the water storage container and the nozzle through the pipeline; the switching assembly includes: a rotating body, multiple movable baffles, and a drive unit.

[0010] A rotating body is coaxially sleeved on the outer periphery of a water storage container, and the rotating body and the water storage container are arranged radially at intervals. Multiple movable baffles are arranged sequentially on the outer periphery of the water storage container along the circumference of the water storage container. Each movable baffle is rotatably connected to the water storage container through a pivot. The rotating body is provided with a guide part corresponding to each movable baffle, and the movable baffle is provided with a guided part that is slidably connected to the guide part. A drive unit is used to drive the rotating body to rotate. Through the sliding cooperation between the guide part and the guided part, the multiple movable baffles are driven to rotate relative to the water storage container to achieve synchronous opening and closing, so as to open or close the opening of the water storage container.

[0011] The irrigation device provided in this application embodiment has multiple movable baffles rotatably connected to the outer surface of the water storage container in the switch assembly. The multiple movable baffles and the rotating body are slidably connected through the guide part and the guided part. The drive unit drives the rotating body to rotate. Through the structural design of the guide part and the guided part, the multiple movable baffles can be driven to rotate synchronously. The multiple movable baffles unfold to open the opening of the water storage container, and the multiple movable baffles close to close the opening of the water storage container.

[0012] By adopting the above scheme, the switch assembly realizes the synchronous opening and closing of multiple movable baffles through the mechanical linkage between the drive unit and the rotating body. During rainfall, the movable baffles are opened to collect rainwater, and during non-rainfall periods, the water storage container is closed. The opening and closing of the water storage container is automatically determined according to the water volume inside the container, which effectively improves the automation and ease of operation of the irrigation device and increases the utilization rate of rainwater resources.

[0013] In one possible implementation, each guide portion is configured as a guide groove that penetrates the rotating body radially and extends obliquely along the circumference of the rotating body; the guided portion is configured as a sliding post that passes through the guide groove and can slide relative to the guide groove along the extension direction of the guide groove; the pivot portion is configured on the outer circumferential surface of the water storage container and adjacent to the opening of the water storage container.

[0014] Using the above scheme, when the movable baffle rotates relative to the water storage container about the pivot, the sliding column slides relative to the guide groove in the guide groove.

[0015] In one possible implementation, the pivot is configured as: a connecting shaft protruding from the outer peripheral surface of the water storage container, a connecting hole provided on the movable baffle corresponding to the position of the connecting shaft, the connecting shaft passing through the connecting hole, so that each movable baffle is rotatably connected to the water storage container about the connecting shaft, and the guided part has a first position and a second position in the guide part.

[0016] When the guided part is in the first position, multiple movable baffles unfold to open the opening of the water storage container, and each movable baffle is located between the outer circumferential surface of the water storage container and the inner circumferential surface of the rotating body; when the guided part is in the second position, multiple movable baffles retract to close the opening of the water storage container.

[0017] Using the above scheme, when the guided part is in the first position, multiple movable baffles are in an unfolded state. The movable baffles are located in the radial gap between the outer peripheral surface of the water storage container and the inner wall surface of the rotating body. The unfolded movable baffles avoid the opening area at the top of the water storage container, so that the opening and the through hole of the first part of the outer shell form a through channel. External rainwater flows into the water storage cavity through the through hole, completing the rainwater collection. When the guided part is in the second position, that is, when the sliding column is located at the other end of the guide groove away from the base along the height direction of the irrigation device, multiple movable baffles simultaneously retract towards the center, forming an overlapping covering layer above the opening of the water storage container. The retracted movable baffles are located in the space between the first part of the outer shell and the opening of the water storage container, completely covering the opening area and blocking the communication path between the water storage cavity and the external environment. At this time, the water storage cavity is in a closed state.

[0018] In one possible implementation, the drive unit includes a motor, a drive gear, and a gear ring. The drive gear is mounted on the drive shaft of the motor and meshes with the gear ring. The gear ring is fixedly connected to the rotating body. The motor drives the rotating body to rotate through the meshing of the drive gear and the gear ring.

[0019] Using the above scheme, the motor drives the drive gear to rotate, which in turn drives the gear ring and the rotating body to rotate, realizing the automatic rotation process of the movable baffle and the automatic opening and closing of the switch assembly.

[0020] In one possible implementation, the irrigation device further includes: a filter screen disposed at the opening of the water storage container; the filter screen includes a first filter layer and a second filter layer, the first filter layer having a plurality of first filter holes formed thereon, the second filter layer having a plurality of second filter holes formed thereon, the aperture of the first filter holes being larger than the aperture of the second filter holes, and the first filter layer being disposed on the side of the second filter layer away from the water storage cavity.

[0021] With the above scheme, when rainwater flows through the first filter layer, larger impurities are initially intercepted, and when the water continues to flow through the second filter layer, smaller impurities are secondary intercepted, forming a gradient filtration structure, which significantly reduces the risk of excessive impurities in the water storage chamber clogging the irrigation device.

[0022] In one possible implementation, the water storage container is provided with a partition that divides the interior of the water storage container into a water storage chamber and a receiving chamber that are independent of each other; the water pump is located in the receiving chamber, and the pipeline includes a first pipeline, a second pipeline and at least one third pipeline. The two ends of the first pipeline are respectively connected to the water storage chamber and the water inlet of the water pump, the second pipeline is connected to the water outlet of the water pump, and the two ends of the third pipeline are connected to the second pipeline and the nozzle.

[0023] Using the above scheme, the separator divides the interior of the water storage container into two independent cavities distributed along the axis. The water storage cavity is located above the partition and is used to contain irrigation water, while the receiving cavity is located below the partition and is used to support functional components.

[0024] In one possible implementation, the irrigation device further includes a housing, which includes a base and an outer shell. The outer shell is connected above the base, and the bottom of the water storage container is fixed to the inner wall of the base. The outer shell includes a first part and a second part. The first part surrounds the outer periphery of the opening of the water storage container. When the multiple movable baffles are closed, the multiple movable baffles are located between the opening and the first part. The second part is coaxially sleeved on the outer periphery of the rotating body and connected to the base. The ends of the first part and the second part away from the base are connected.

[0025] The first part has a plurality of through holes spaced apart circumferentially along the first part, each through hole penetrating the wall of the first part and facing the opening of the water storage container; the outer surface of the second part has a plurality of grooves spaced apart circumferentially along the second part, and the outer surface of the second part is coated with a luminescent coating.

[0026] Using the above scheme, the through-hole in the first part is used to collect rainwater, improving the utilization rate of rainwater by the irrigation device. The inner surface of the groove in the second part is coated with a luminescent coating. The concave inner surface of the groove helps to concentrate and guide light, so that the outer shell of the irrigation device not only has the function of collecting rainwater, but also has a certain luminescent function, realizing the position indication or device function at night or in low light environment.

[0027] In one possible implementation, the sprinkler head includes a drip irrigation sprinkler head, a sprinkler irrigation sprinkler head, and a switching valve, the switching valve being used to switch the operating states of the drip irrigation sprinkler head and the sprinkler irrigation sprinkler head.

[0028] In one possible implementation, the irrigation device further includes: a retaining ring, a mounting bracket, and a solar panel. The retaining ring is mounted on the end of the rotating body axially close to the opening. The retaining ring has a mating part, and the rotating body has a mating groove. The mating part is embedded in the mating groove. The mounting bracket is connected to the end of the retaining ring away from the rotating body, and the solar panel is mounted on the mounting bracket.

[0029] Using the above scheme, the lower end of the mounting bracket along the height direction of the irrigation device is connected to the other side of the retaining ring along the height direction of the irrigation device away from the rotating body, and the upper end of the mounting bracket along the height direction of the irrigation device is connected to the solar panel. The upper end of the mounting bracket passes through the top of the first part to install the solar panel on the top of the irrigation device.

[0030] In one possible implementation, the irrigation device further includes: a storage battery, a humidity detection module, a water level detection module, and a control unit; when the irrigation device includes a housing and a solar panel, the storage battery is located inside the base of the housing and is electrically connected to the solar panel; the detection end of the humidity detection module extends out of the base through the bottom wall of the base; the water level detection module is located inside the water storage chamber of the water storage container; the control unit is electrically connected to the storage battery, the water level detection module, the humidity detection module, and the drive unit respectively.

[0031] By adopting the above scheme, the irrigation device can automatically adjust the irrigation mode according to the soil moisture, and automatically open the water storage container to replenish the water or close the water storage container to prevent evaporation, which can effectively improve the utilization rate of water resources and improve the automation level of the irrigation device.

[0052] A. The height direction of the irrigation device. Detailed Implementation

[0053] In existing irrigation technologies, the tops of water storage containers (such as pools, tanks, and rainwater collection buckets) are typically designed to be completely open or simply covered. This design leads to the following major drawbacks: A large area of ​​water within the storage chamber is exposed to the air, especially in arid, hot, or windy regions, resulting in extremely high evaporation rates and significant water waste; the open storage container easily allows external impurities such as leaves, dust, insects, bird droppings, and algae spores to fall into the water. These impurities are carried into the irrigation system (pumps, pipes, sprinklers) by the water flow, easily causing blockages, especially at fine sprinklers. These impurities, carried into the system (including pumps, pipes, and sprinklers), easily accumulate on the inner walls of the pipes, eventually clogging the fine water outlets. Frequent blockages increase the workload and cost of manual cleaning and maintenance, and reduce or even interrupt irrigation efficiency; frequent blockages require manual cleaning, increasing maintenance costs and affecting irrigation efficiency; even with simple coverings (such as manual covers or tarpaulins), manual operation is time-consuming and labor-intensive for large storage containers or scenarios requiring frequent irrigation, making it impractical; the covering function of the storage container and the start / stop of the irrigation system are usually managed independently, lacking an intelligent linkage mechanism. Users may neglect to close the cover, exacerbating evaporation loss and pollution risks, or forget to open the cover, hindering rainwater collection or affecting normal irrigation operations.

[0054] Therefore, the core drawbacks of existing irrigation systems are low water resource utilization and poor impurity prevention, leading to a high clogging rate.

[0055] To address the aforementioned technical problems, this application provides an irrigation device. This device features an automatically opening and closing switch assembly on a water storage container, allowing the container to automatically open when rainwater collection is needed and automatically close when rainwater collection is not required. This effectively solves the problems of low water resource utilization and high clogging rate in existing irrigation devices.

[0056] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of the irrigation device 100 according to an embodiment of this application.

[0057] like Figure 1 As shown, the irrigation device 100 includes a housing 5, which includes a base 52 and an outer shell 51. The outer shell 51 is connected above the base 52 and includes a first part 511 and a second part 513. The second part 513 is connected to the base 52, and the first part 511 and the second part 513 are connected to the ends of the second part 513 away from the base 52.

[0058] The irrigation device 100 has a height direction, and the base 52 is configured to support the irrigation device 100. The base 52 is located at the bottom of the irrigation device 100 along the height direction, and a fixing structure is formed at the bottom end of the base 52 along the height direction A of the irrigation device to facilitate fixing the irrigation device 100 to the ground. The fixing structure can be a fastener or other connection structure, and this embodiment is not limited to this only.

[0059] The outer casing 51 is connected to the base 52 above it along the height direction A of the irrigation device, together forming a cavity to accommodate other components of the irrigation device 100. In one possible embodiment, along the height direction A of the irrigation device, the first part 511, the second part 513, and the base 52 are arranged sequentially, with the lower end of the first part 511 detachably engaged with the upper end of the second part 513. Preferably, the first part 511 and the second part 513 can be connected by a threaded connection or a snap-fit ​​connection. The first part 511 and the second part 513 can also be connected by other structures, which is not limited in this embodiment. The lower end of the second part 513 is connected to the upper end of the base 52, and the second part 513 and the base 52 can be connected by a snap-fit ​​structure. The second part 513 and the base 52 can also be connected by fasteners or other connection methods, which is not limited in this embodiment.

[0060] Using the above solution, this embodiment designs the outer casing 51 as a detachable first part 511 and a second part 513. The first part 511 is easy to disassemble, allowing users to install, maintain, repair, or replace the components housed inside without disassembling the entire device. The outer casing 51 protects the internal components, extending the service life of the irrigation device 100 and improving its operational reliability. The base 52 supports and secures the entire device, ensuring the stability of the irrigation device 100 on the bottom surface.

[0061] like Figure 1 and Figure 2As shown, in one possible implementation, a plurality of through holes 512 are formed on the first part 511 at intervals along the circumference of the first part 511. Each of the plurality of through holes 512 penetrates the wall of the first part 511. The first part 511 has a plurality of through holes 512 evenly spaced along the circumference of the first part 511. The plurality of through holes 512 are arranged in a circumferential array on the first part 511. Each through hole 512 penetrates the wall thickness of the first part 511 and is used to guide external rainwater into the interior of the irrigation device 100.

[0062] like Figure 1 and Figure 2 As shown, the outer surface of the second part 513 has a plurality of grooves 514 spaced apart circumferentially along the second part 513, and the outer surface of the second part 513 is coated with a light-emitting coating.

[0063] A plurality of grooves 514 are formed on the outer surface of the second part 513, and the grooves 514 are evenly spaced along the circumference of the second part 513. Each groove 514 is formed by a radial inward recess of at least a portion of the outer surface of the second part 513. The inner surface of the groove 514 can be an arc-shaped structure or other multifaceted structures, which are not limited to this embodiment. A luminescent coating covers the inner surface of the grooves 514 and other areas on the outer surface of the second part 513 except for the grooves 514. The luminescent coating is a long-lasting phosphorescent material, such as a coating that can absorb visible light and release afterglow, and its continuous luminescence time can, for example, exceed 12 hours. Preferably, the luminescent coating can be a rare-earth-doped aluminate luminescent coating. The core component of this rare-earth-doped aluminate luminescent coating is strontium aluminate as a matrix, modified by doping with europium as an activator and dysprosium as a co-activator. After absorbing visible light, the rare-earth ions in the crystal lattice structure capture energy and slowly release it, forming a long-lasting afterglow luminescence. This coating, through a special process, is non-toxic and non-radioactive, and is widely used in coatings, inks, and other fields, with a luminescence duration exceeding twelve hours. The luminescent coating in this embodiment can also be made of other materials; this embodiment does not limit it to a single material. The edge shape of the groove 514 can be honeycomb-shaped, circular, or other polygonal; this embodiment does not limit it to a single material.

[0064] Using the above scheme, the through hole 512 in the first part 511 is used to collect rainwater, improving the utilization rate of rainwater by the irrigation device 100. The inner surface of the groove 514 on the second part 513 is coated with a luminescent coating. The concave inner surface of the groove 514 helps to concentrate and guide light, so that the outer shell 51 of the irrigation device 100 not only has the function of collecting rainwater, but also has a certain luminescent function, realizing the functions of position indication, lighting or decoration at night or in low light environment.

[0065] like Figure 2 and Figure 3 As shown, in one possible embodiment, the irrigation device 100 includes: a water storage container 1, the bottom of which is fixed to the inner wall of the base 52. The water storage container 1 has a water storage cavity 11 formed around it, and the top of the water storage container 1 has an opening 15 to allow the water storage cavity 11 to communicate with the external space of the water storage container 1 through the opening 15. A first part 511 surrounds the outer periphery of the opening 15 of the water storage container 1, and a through hole 512 is opposite to the opening 15 of the water storage container 1.

[0066] The water storage container 1 is fixedly connected to the inner surface of the bottom wall of the base 52 along the height direction of the irrigation device 100. The first part 511 and the second part 513 surround the outside of the water storage container 1. The top of the water storage container 1 along the height direction A of the irrigation device has an opening 15. Specifically, the projection of the opening 15 along the height direction A of the irrigation device covers the projection of a plurality of through holes 512.

[0067] The multiple through holes 512 of the first part 511 are opposite to the opening 15 of the water storage container 1 along the height direction A of the irrigation device, forming a water collection channel. Rainwater can enter the water storage cavity 11 through the through holes 512 and the opening 15 to improve the utilization rate of rainwater by the irrigation device 100. The design of the through holes 512 of the first part 511 can also play a preliminary anti-clogging role to prevent large impurities from falling into the water storage cavity 11.

[0068] like Figure 2 and Figure 3 As shown, in one possible embodiment, the irrigation device 100 further includes a filter screen 4, which is disposed at the opening 15 of the water storage container 1. The filter screen 4 includes a first filter layer 41 and a second filter layer 42. A plurality of first filter holes 411 are formed on the first filter layer 41, and a plurality of second filter holes 421 are formed on the second filter layer 42. The aperture of the first filter holes 411 is larger than the aperture of the second filter holes 421. The first filter layer 41 is disposed on the side of the second filter layer 42 away from the water storage chamber 11.

[0069] A removable filter screen 4 is provided at the opening 15 of the water storage container 1. Multiple mounting grooves 16 are formed at the opening 15 of the water storage container 1, and these grooves are evenly distributed circumferentially along the opening 15. Multiple mounting portions 43 are formed on the radially outer peripheral wall of the filter screen 4, and these portions are evenly distributed circumferentially along the filter screen 4. Each mounting portion 43 corresponds to one of the mounting grooves 16. The filter screen 4 and the water storage container 1 are detachably assembled through the cooperation between the mounting portions 43 and the mounting grooves 16. The shapes of the mounting portions 43 and the mounting grooves 16 are adapted to each other; however, this embodiment does not impose a unique limitation on the specific structure of the mounting portions 43 and the mounting grooves 16.

[0070] The filter screen 4 includes a first filter layer 41 and a second filter layer 42 arranged sequentially along the height direction A of the irrigation device. The second filter layer 42 is disposed adjacent to the water storage chamber 11, and the first filter layer 41 is disposed on the side of the second filter layer 42 away from the water storage chamber 11. The first filter layer 41 has a plurality of first filter holes 411 penetrating through it, and the second filter layer 42 has a plurality of second filter holes 421 penetrating through it. The first filter layer 41 and the second filter layer 42 are spaced apart along the height direction A of the irrigation device, and the diameter of the first filter holes 411 is larger than the diameter of the second filter holes 421. Along the height direction A of the irrigation device, the first filter holes 411 and the second filter holes 421 can be partially opposite, completely opposite, or not opposite; this embodiment does not impose a unique limitation on this.

[0071] Using the above scheme, during the rainwater collection process, the filter screen 4 can perform dual filtration of the rainwater. When the rainwater flows through the first filter layer 41, larger impurities are initially intercepted. When the water continues to flow through the second filter layer 42, smaller impurities are secondary intercepted, forming a gradient filtration structure. This significantly reduces the risk of excessive impurities in the water storage chamber 11 clogging the irrigation device 100. The detachable design of the filter screen 4 also makes it convenient for users to clean the irrigation device 100 regularly, extending the service life of the irrigation device 100.

[0072] like Figure 2 and Figure 3 As shown, in one possible embodiment, the water storage container 1 includes a pivot portion 13, which is configured as a connecting shaft protruding from the outer peripheral surface of the water storage container 1. The pivot portion 13 is disposed on the outer peripheral surface of the water storage container 1 and adjacent to the opening 15 of the water storage container 1. There are multiple pivot portions 13, which are evenly spaced along the circumference of the water storage container 1.

[0073] In one possible implementation, such as Figure 2 and Figure 3 As shown, the irrigation device 100 also includes: a retaining ring 6, a mounting bracket 73 and a solar panel 71. The retaining ring 6 is installed on one end of the rotating body 31 along the axial direction near the opening 15. The retaining ring 6 has a mating part 61, and the rotating body 31 has a mating groove 312. The mating part 61 is embedded in the mating groove 312.

[0074] The retaining ring 6 has at least one mating part 61 on one side of the rotating body 31 along the height direction A of the irrigation device. The rotating body 31 has a corresponding mating groove 312 at its upper end along the height direction of the irrigation device 100. The mating part 61 and the mating groove 312 are matched in structure. The mating part 61 is embedded in the mating groove 312, so that the retaining ring 6 is fixedly connected to the rotating body 31.

[0075] Mounting bracket 73 is connected to the end of retaining ring 6 away from rotating body 31, and solar panel 71 is mounted on mounting bracket 73. The lower end of mounting bracket 73 along the height direction A of irrigation device is connected to the other side of retaining ring 6 along the height direction A of irrigation device away from rotating body 31, and the upper end of mounting bracket 73 along the height direction A of irrigation device is connected to solar panel 71. The upper end of mounting bracket 73 passes through the top of first part 511, fixing solar panel 71 to the top of irrigation device 100.

[0076] By adopting the above scheme, the solar panel 71 is placed on the top of the irrigation device 100 through the retaining ring 6 and the mounting bracket 73, so that the irrigation device 100 can collect solar energy and convert it into electrical energy, thereby improving the energy utilization rate of the irrigation device 100 and realizing automation.

[0077] like Figure 3 and Figure 4 As shown, in one possible embodiment, the irrigation device 100 further includes a switch assembly 3, which includes a rotating body 31. The rotating body 31 is coaxially sleeved on the outer periphery of the water storage container 1, and the rotating body 31 and the water storage container 1 are arranged radially spaced apart. A second part 513 is coaxially sleeved on the outer periphery of the rotating body 31.

[0078] Along the radial direction of the water storage container 1, there is a certain gap between the inner wall surface of the rotating body 31 and the outer peripheral surface of the water storage container 1. Along the radial direction of the water storage container 1, the water storage container 1, the rotating body 31 and the second part 513 are nested in sequence.

[0079] like Figure 3 and Figure 4 As shown, the switch assembly 3 also includes multiple movable baffles 32. The multiple movable baffles 32 are arranged sequentially on the outer periphery of the water storage container 1 along the circumference of the water storage container 1. Each of the multiple movable baffles 32 is rotatably connected to the water storage container 1 through a pivot part 13. The movable baffles 32 are provided with connecting holes 322 at the positions corresponding to the connecting shafts. The connecting shafts pass through the connecting holes 322 so that each movable baffle 32 is rotatably connected to the water storage container 1 with the connecting shafts as the axis.

[0080] Each movable baffle 32 is provided with a connecting hole 322 that penetrates the wall thickness of the movable baffle 32. The connecting hole 322 of each movable baffle 32 cooperates with the pivot part 13 on the outer peripheral surface of the water storage container 1. Multiple pivot parts 13 are correspondingly provided with multiple movable baffles 32. The pivot part 13 passes through the connecting hole 322 of the movable baffle 32 to form a rotating pair, so that the movable baffle 32 can be rotatably connected to the outer peripheral surface of the water storage container 1 with the pivot part 13 as the axis.

[0081] like Figure 3 and Figure 4As shown, in one possible implementation, the rotating body 31 is provided with a guide portion 311 corresponding to each movable baffle 32, and the movable baffle 32 is provided with a guided portion 321 that is slidably connected to the guide portion 311. Each guide portion 311 is configured as a guide groove that penetrates the rotating body 31 radially and extends obliquely along the circumference of the rotating body 31; the guided portion 321 is configured as a sliding post that passes through the guide groove and can slide relative to the guide groove along the extension direction of the guide groove.

[0082] The rotating body 31 has a guide groove extending radially inclined along its inner wall. The guide groove can be formed by recessing at least a portion of the inner wall surface of the rotating body 31 radially away from the water storage container 1. Alternatively, the guide groove can be formed by penetrating the rotating body 31 radially. This embodiment does not limit the structure of the guide groove to a single feature. Each movable baffle 32 has a sliding column corresponding to the guide groove position. One end of the sliding column is connected to the surface of the movable baffle 32 away from the water storage container 1, and the other end is embedded in the guide groove to form a sliding pair. Multiple guide grooves are formed on the rotating body 31, and these guide grooves correspond to multiple movable baffles 32. When the movable baffle 32 rotates relative to the water storage container 1 about the pivot 13, the sliding column slides relative to the guide groove within the guide groove.

[0083] like Figure 3 and Figure 4 As shown, in one possible embodiment, the switch assembly 3 further includes a drive unit 33, which includes a motor 331, a drive gear 333, and a gear ring 334. The drive gear 333 is mounted on the drive shaft 332 of the motor 331 and meshes with the gear ring 334. The gear ring 334 is fixedly connected to the rotating body 31. The motor 331 drives the rotating body 31 to rotate through the meshing of the drive gear 333 and the gear ring 334. The drive unit 33 is used to drive the rotating body 31 to rotate. Through the sliding cooperation between the guide part 311 and the guided part 321, it drives multiple movable baffles 32 to rotate relative to the water storage container 1 to achieve synchronous opening and closing, thereby opening or closing the opening 15 of the water storage container 1.

[0084] The motor 331 is housed within the base 52. The drive shaft 332 of the motor 331 passes through the upper wall of the base 52 along the height direction of the irrigation device 100 and extends out of the base 52. A drive gear 333 is coaxially and fixedly connected to the end of the drive shaft 332. A gear ring 334 is fitted onto the outer circumferential surface of the water storage container 1 near the base 52. The gear ring 334 is connected to the bottom of the rotating body 31 along the height direction A of the irrigation device, and the gear ring 334 meshes with the drive gear 333 to form a meshing pair. The output torque of the motor 331 is transmitted to the gear ring 334 via the drive gear 333, causing the rotating body 31 to rotate. A guide groove extending circumferentially on the rotating body 31 pushes the sliding column relative to the guide groove, forcing multiple movable baffles 32 to rotate synchronously around the pivot axis.

[0085] Using the above scheme, the switch assembly 3 achieves the synchronous opening and closing of multiple movable baffles 32 through the mechanical linkage between the drive unit 33 and the rotating body 31. During rainfall, the movable baffles 32 are opened to collect rainwater, and during non-rainfall periods, the water storage container 1 is closed. The opening and closing of the water storage container 1 is automatically determined according to the water volume inside the water storage container 1, which effectively improves the automation and ease of operation of the irrigation device 100 and increases the utilization rate of rainwater resources by the irrigation device 100.

[0086] Specifically, such as Figure 3 and Figure 4 As shown, the guided part 321 has a first position and a second position within the guide part 311. When the guided part 321 is in the first position, multiple movable baffles 32 unfold to open the opening 15 of the water storage container 1, and each movable baffle 32 is located between the outer peripheral surface of the water storage container 1 and the inner peripheral surface of the rotating body 31. When the guided part 321 is in the first position, that is, when the sliding column is located at one end of the guide groove along the height direction A of the irrigation device near the base 52, the multiple movable baffles 32 are in the unfolded state. The movable baffles 32 are located in the radial gap between the outer peripheral surface of the water storage container 1 and the inner wall surface of the rotating body 31. The unfolded movable baffles 32 avoid the area of ​​the opening 15 at the top of the water storage container 1, so that the opening 15 and the through hole 512 of the first part 511 of the outer shell 51 form a through channel. External rainwater flows in through the through hole 512 and enters the water storage chamber 11 through the double-layer filtration structure of the filter screen 4 in sequence, thus completing the rainwater collection.

[0087] At this time, the unfolding angle of the movable baffle 32 maximizes the effective collection area of ​​the opening 15, while the movable baffle 32 itself is located in the annular space between the water storage container 1 and the rotating body 31, avoiding obstruction of the water flow path.

[0088] When the guided part 321 is in the second position, the multiple movable baffles 32 retract to close the opening 15 of the water storage container 1. When the multiple movable baffles 32 retract, they are located between the opening 15 and the first part 511. When the guided part 321 is in the second position, that is, when the sliding column is located at the other end of the guide groove along the height direction A of the irrigation device away from the base 52, the multiple movable baffles 32 retract synchronously towards the center, forming an overlapping covering layer above the opening 15 of the water storage container 1. The retracted movable baffles 32 are entirely located in the space between the first part 511 of the outer shell 51 and the opening 15 of the water storage container 1, completely covering the area of ​​the opening 15 and blocking the communication path between the water storage cavity 11 and the external environment. At this time, the water storage cavity 11 is in a closed state.

[0089] Combination Figure 3 and Figure 4 The mechanical transmission relationship shown, in one possible implementation, the specific movement process of the switch assembly 3 is as follows:

[0090] When the drive shaft 332 of the motor 331 drives the drive gear 333 to rotate counterclockwise, the drive gear 333 meshes with the gear ring 334, forcing the gear ring 334 to rotate clockwise. The gear ring 334 is fixedly connected to the rotating body 31, driving the rotating body 31 to rotate clockwise synchronously. The guide groove pushes the slide column to move obliquely downward along the extension direction of the guide groove. The displacement of the slide column forces the movable baffle 32 to rotate counterclockwise around the pivot part 13. All movable baffles 32 unfold synchronously. The unfolded movable baffles 32 completely move out of the opening 15 area of ​​the water storage container 1, so that the opening 15 and the through hole 512 of the outer shell 51 form a continuous water collection channel. At this time, the slide column moves from the second position (closed position) to the first position (open position), and the water storage container 1 enters the rainwater collection state.

[0091] When the drive shaft 332 of the motor 331 drives the drive gear 333 to rotate clockwise, the drive gear 333 meshes with the gear ring 334, forcing the gear ring 334 to rotate counterclockwise. The gear ring 334 is fixedly connected to the rotating body 31, driving the rotating body 31 to rotate counterclockwise synchronously. The guide groove pushes the slide column to move obliquely upward along the extension direction of the guide groove. The displacement of the slide column pulls the movable baffle 32 to rotate clockwise around the pivot part 13. All the movable baffles 32 retract synchronously, and the retracted movable baffles 32 completely cover the opening 15 of the water storage container 1, forming a closed interface. At this time, the slide column returns from the first position (open position) to the second position (closed position), and the water storage container 1 enters the anti-evaporation sealed state.

[0092] In one possible implementation, such as Figure 5 As shown, the irrigation device 100 also includes a storage battery 72, which is located inside the base 52 of the housing 5 and is electrically connected to the solar panel 71. The storage battery 72 can store the electricity collected by the solar panel 71, enabling the irrigation device 100 to operate continuously without an external power source, thus preventing the equipment from shutting down on rainy days or at night.

[0093] like Figure 5 As shown, in one possible implementation, the water storage container 1 is provided with a partition 14 inside, which divides the interior of the water storage container 1 into a water storage cavity 11 and a receiving cavity 12 that are independent of each other.

[0094] The partition 14 is a baffle perpendicular to the container axis, with its edge sealed to the inner wall of the water storage container 1. The partition 14 divides the interior of the water storage container 1 into two independent axially distributed cavities: a water storage cavity 11 located above the baffle for containing irrigation water, and a receiving cavity 12 located below the baffle for supporting functional components. The partition 14 has a connecting hole.

[0095] The irrigation device 100 also includes a water level detection module (not shown in the figure), which is located inside the water storage chamber 11 of the water storage container 1. The water level detection module is used to detect the amount of water in the water storage chamber 11.

[0096] like Figure 4 and Figure 5 As shown, in one possible implementation, the irrigation assembly 2 includes a water pump 21, a pipe 22, and a nozzle 23. The water pump 21 is connected to the water storage container 1 and the nozzle 23 via the pipe 22. The water pump 21 is located inside the receiving cavity 12. The pipe 22 includes a first pipe 221, a second pipe 222, and at least one third pipe 223. The two ends of the first pipe 221 are connected to the water storage cavity 11 and the inlet of the water pump 21, respectively. The second pipe 222 is connected to the outlet of the water pump 21. The two ends of the third pipe 223 are connected to the second pipe 222 and the nozzle 23.

[0097] One end of the first pipe 221 is connected to the connecting hole on the separator 14, and the other end of the first pipe 221 is connected to the inlet of the water pump 21, which can draw water from the water storage chamber 11 into the water pump 21. The second pipe 222 can be a ring structure and is connected to the outlet of the water pump 21. There are multiple third pipes 223, which extend radially along the base 52 and are evenly spaced along the circumference of the water storage container 1. One end of the third pipe 223 is connected to the second pipe 222, and the other end of the third pipe 223 passes through the water storage container 1 and extends out of the side wall of the base 52. The other end of the third pipe 223 is connected to the nozzle 23.

[0098] Using the above scheme, the partition 14 facilitates the physical isolation between electrical components and water. The annular second pipe 222 can achieve equal pressure distribution of water volume, ensuring balanced flow of each nozzle 23. The radial arrangement of multiple third pipes 223 can shorten the water flow path, reduce pressure loss, and ensure that the water in the water storage chamber 11 is efficiently transported to the nozzle 23 and flows out through the nozzle 23 to complete irrigation.

[0099] In one possible implementation, such as Figure 4 and Figure 5 As shown, the nozzle 23 includes a drip irrigation nozzle 231, a sprinkler irrigation nozzle 232, and a switching valve. The switching valve is used to switch the working states of the drip irrigation nozzle 231 and the sprinkler irrigation nozzle 232.

[0100] Along the height direction A of the irrigation device, the sprinkler head 232 is positioned above the drip irrigation head 231. The drip irrigation head 231 is equipped with a slender flow channel and an array of drip holes for point-source seepage irrigation, while the sprinkler head 232 is equipped with a swirling chamber and atomizing nozzles for area spraying. The sprinkler head 232 has a dual-chamber isolation structure, and the switching valve has parallel dual channels connecting the drip irrigation channel and the sprinkler irrigation channel respectively. When the switching valve is in the first working state, the channel connected to the drip irrigation head 231 is open, i.e., the low-pressure water valve is open and the high-pressure valve is closed, and the water flow forms intermittent drips after being throttled and depressurized. When the switching valve is in the second working state, the channel connected to the sprinkler head 232 is open, i.e., the high-pressure water valve is open and the low-pressure valve is closed, and the water flow is accelerated by high pressure and centrifugally atomized.

[0101] The switching valve is electrically connected to the storage battery 72, which provides energy to the switching valve to enable automatic switching, thereby enabling the sprinkler head 23 to automatically switch between different irrigation modes.

[0102] In one possible implementation, such as Figure 5 and Figure 6 As shown, the irrigation device 100 also includes a humidity detection module 81 and a control unit. The detection end of the humidity detection module 81 extends out of the base 52 through the bottom wall of the base 52. The control unit is electrically connected to the battery 72, the water level detection module, the humidity detection module 81 and the drive unit 33 respectively.

[0103] A humidity detection module 81 is housed inside the base 52. The detection end of the module 81 extends vertically through the bottom wall of the base 52 to the external soil to detect soil moisture. The control unit is electrically connected to the humidity detection module 81, battery 72, water pump 21, and sprinkler head 23. The battery 72 powers the control unit, humidity detection module 81, water pump 21, and sprinkler head 23. The humidity detection module 81 works by using two metal electrodes to form a capacitor plate, with the soil acting as the dielectric. Changes in soil moisture directly alter the capacitance value, which is then converted into a percentage of humidity. When the humidity detection module 81 detects soil moisture below a preset value, the control unit triggers the water pump 21 to start and selects either sprinkler or drip irrigation mode based on the real-time humidity.

[0104] The control unit is electrically connected to the water level detection module and the motor 331. When the water level detection module detects that the water level in the water storage chamber 11 is lower than the first preset value, the control unit sends an opening command to the motor 331. The motor 331 drives the movable baffle 32 to unfold and open the opening 15 of the water storage container 1, so that the opening 15 of the water storage chamber 11 remains open until the water level rises. When the water level detection module detects that the water level in the water storage chamber 11 is higher than the second preset value, the control unit sends a closing command to the motor 331. The motor 331 drives the movable baffle 32 to close and close the opening 15 of the water storage container 1, and the water storage chamber 11 enters a closed state.

[0105] In summary, the irrigation device 100 can automatically adjust the irrigation mode according to the soil moisture, and automatically open the water storage container 1 to replenish water or close the water storage container 1 to prevent evaporation, which can effectively improve the utilization rate of water resources and enhance the automation level of the irrigation device 100.
