DETAILED DESCRIPTION
[0021] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figure 1 to Figure 5 As shown, this embodiment proposes an automatic watering device, including a protective outer cylinder 1, a water storage cylinder 4, and a protective cover 3. The protective outer cylinder 1 is provided with a grid-shaped opening, the water storage cylinder 4 is located inside the protective outer cylinder 1, the protective cover 3 is located on the upper side of the protective outer cylinder 1, and a control cylinder 5 is provided between the protective outer cylinder 1 and the water storage cylinder 4. The protective outer cylinder 1 and the water storage cylinder 4 are both slidably connected to the control cylinder 5. The water storage cylinder 4 is provided with a plurality of first water discharge openings 42, and the control cylinder 5 is provided with a plurality of second water discharge openings 53. The positions of the first water discharge openings 42 and the second water discharge openings 53 correspond to each other one by one. The control cylinder 5 is divided by the second water discharge openings 53. The wall area is larger than the first open opening area. A rotating structure and a second water pipe 51 are fixedly connected to the upper side of the control cylinder 5. The second water pipe 51 is located in the middle of the upper side of the control cylinder 5. One end of the second water pipe 51 is located inside the water storage cylinder 4. A control cover 2 is arranged between the protective outer cylinder 1 and the protective cover 3. The control cover 2 is detachably connected to the protective outer cylinder 1 and the protective cover 3. The control cover 2 is fixedly connected to a driving structure for driving the rotating structure to rotate and a first water pipe. The first water pipe is connected to the second water pipe 51. One end of the first water pipe away from the second water pipe 51 passes through the protective cover 3 and is located outside the protective cover 3.
[0023] In this embodiment, the protective outer cylinder 1 is used to protect the internal control cylinder 5 and water storage cylinder 4, and is also used to prevent soil and plant roots from entering the control cylinder 5 and water storage cylinder 4, and to prevent soil or plant roots from being blocked between the control cylinder 5 and the water storage cylinder 4, resulting in the control cylinder 5 being unable to control the release of water in the water storage cylinder 4. The grid-shaped openings of the protective outer cylinder 1 should be evenly distributed on the cylinder wall of the protective outer cylinder 1, and the opening area of the grid-shaped openings should not be too large. An opening area of an excessively large grid-shaped opening cannot effectively block the soil and plant roots; the water storage cylinder 4 It is used to store water. One end of the first water pipe located outside the protective cover 3 is connected to the external water pipe. The external water pipe transfers water into the water storage cylinder 4 through the first water pipe and the second water pipe 51. Since the control cylinder 5 can rotate, the first water pipe and the second water pipe 51 are designed to be split. The second water pipe 51 rotates with the control cylinder 5. The first water pipe is fixed. The first water pipe 20 should be inserted into the second water pipe 51, which can effectively prevent water leakage. The protective cover 3 is used to protect the control cover 2 to prevent the control cover 2 from entering. The control cylinder 5 is used to control the release of water in the water storage cylinder 4. When the first water discharge opening 42 coincides with the second water discharge opening 53, the water in the water storage cylinder 4 flows out, and the water flows into the soil through the grid-shaped opening of the protective outer cylinder 1. When the cylinder wall of the control cylinder 5 blocks the first water discharge opening 42, the water in the water storage cylinder 4 stops flowing out. The change of the position of the cylinder wall of the control cylinder 5 and the first water discharge opening 42 is realized by the rotating structure and the driving structure. The driving structure drives the rotating structure to rotate. The rotating structure and the control cylinder 5 are integrated. The rotation of the rotating structure means the rotation of the control cylinder 5. The control cover 2 is used to control the driving structure, that is, to control the rotation of the control cylinder 5. The protective outer cylinder 1, the water storage cylinder 4, the protective cover 3, the control cover 2, and the control cylinder 5 should all be arranged to be detachably connected, so as to facilitate maintenance and replacement of parts. Attention should be paid to draining water during connection. A waterproof strip can be set at the connection, especially at the connection between the control cover 2 and the protective cover 3 and the protective outer cylinder 1. Water ingress into the control cover 2 will cause abnormalities in the driving structure and other parts inside it, and then cause the device to fail to operate normally.
[0024] In this embodiment, the rotating structure includes a gear protrusion 50, the cross section of which is annular, and the second water delivery pipe 51 is located in the middle of the gear protrusion 50; the driving structure includes a gear motor 21, the control cover 2 is fixedly connected with a motor compartment 22, the gear motor 21 is located in the motor compartment 22, and the transmission gear of the gear motor 21 is meshed with the gear protrusion 50. Through the meshing of the gear protrusion 50 and the gear motor 21, the rotation of the control cylinder 5 can be accurately controlled; the motor compartment 22 is used to fix the position of the gear motor 21, and is also used to protect the gear motor 21 to prevent the gear motor 21 from entering water.
[0025] In this embodiment, the control cylinder 5 is provided with a waterproof protrusion 52, which is located at the end where the second water delivery pipe 51 is located, and the waterproof protrusion 52 extends from the control cylinder 5 to the protective outer cylinder 1, and the waterproof protrusion 52 abuts against the protective outer cylinder 1. The waterproof protrusion 52 is used to prevent moisture from entering the connection between the gear protrusion 50 and the gear motor 21, to prevent moisture from affecting the operation of the gear protrusion 50 and the gear motor 21, and to prevent moisture from entering the motor compartment 22 through the connection between the gear protrusion 50 and the gear motor 21, causing motor failure.
[0026] In this embodiment, the water storage cylinder 4 is fixedly connected with a threaded fixing protrusion 40, a fixing groove 41, and a drain outlet 43. The water storage cylinder 4 is threadedly connected to the protective outer cylinder 1 through the threaded fixing protrusion 40. The end of the control cylinder 5 away from the first water pipe is embedded in the fixing groove 41, and the drain outlet 43 is located between the threaded fixing protrusion 40 and the fixing groove 41. The threaded fixing protrusion 40 is used to fix with the protective outer tube 1. The connection between the protective outer tube 1 and the threaded fixing protrusion 40 should be provided with a corresponding thread so that it can be connected and fixed with the threaded fixing protrusion 40. The connection between the protective outer tube 1 and the water storage tube 4 connected by the thread is more stable and easy to disassemble; the fixing groove 41 is used to fix the position of the control tube 5. The control tube 5 rotates in the fixing groove 41. The fixing groove 41 enables the control tube 5 to stably realize its function; the drain port 43 is used to discharge water to the lower end of the device, so that the soil at the lower end of the device can also be quickly moistened, and the drain port 43 can also discharge the soil entering the protective outer tube 1 from the grid-shaped opening of the protective outer tube 1. Although the protective outer tube 1 can resist most of the soil and prevent it from entering the interior of the protective outer tube 1, when the water is released, some soil will still enter the interior of the protective outer tube 1 through the water. At this time, these soils can be discharged from the protective outer tube 1 through the drain port 43 when the waterproofing stops, thereby avoiding the accumulation of soil in the protective outer tube 1.
[0027] In this embodiment, the control cover 2 is fixedly connected with a battery 23 and a controller 24. The controller 24 is provided with a soil moisture sensor 25. The soil moisture sensor 25 is electrically connected to the controller 24 through a wire. The battery 23 is electrically connected to the controller 24 and the drive structure. The battery 23 is used to provide power to the gear motor 21 and the controller 24. The battery 23 should be provided with a battery cover. The battery cover is detachably connected to the battery 23 housing. The battery cover is used to facilitate the staff to replace the battery. The controller 24 is used to control the gear motor 21. The controller 24 includes a control chip and a timer. The specific models of the control chip and the timer are not limited. All models that can meet the requirements of the device can be used. The timer is used to realize timed water discharge. The control chip is used to realize control of the gear motor 21 and the control timer. The controller 24 should also be provided with a control button. The control button is used to reset the position of the control cylinder 5. When the device needs to be disassembled to clean the control cylinder 5 or protect the outer cylinder 1 or the water storage cylinder 4, the position of the control cylinder 5 will inevitably change, and the controller 24 will be unable to determine whether the first water discharge opening 42 and the second water discharge opening 53 overlap. Therefore, it is necessary to manually reset through the control button so that the controller 24 can clearly know the current position of the control cylinder 5. The controller 24 can also be provided with a display screen for simply displaying current soil moisture, water discharge times and other data; the soil moisture sensor 25 is used to provide the controller 24 with the current soil moisture so that the controller 24 can discharge or stop water according to the soil moisture.
[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
