Technical Field
[0001] This utility model relates to the field of bird feeders, and in particular to a ceramic bird feeder that can collect rainwater. Background Technology
[0002] With increasing awareness of urban ecological protection, bird feeders are widely used in parks, courtyards, and other settings. Existing technology (such as CN218457054U) proposes a ceramic bird feeder that, through the design of a storage bin, an automatic feeding mechanism, and a rain shield, achieves automatic feed dispensing and rain protection, effectively reducing feed waste and improving the comfort of birds while feeding. However, this technical solution has the following shortcomings: Waste of rainwater resources: Bird feeders do not integrate rainwater collection functions and rely on manual water addition or external water sources. In rainy areas, they cannot utilize natural precipitation, resulting in waste of water resources.
[0003] The water feeding system lacks automatic adjustment: the water level in the water trough needs to be monitored and water is added manually. It cannot automatically adjust the water volume according to the birds' drinking or evaporation. It is easy for the water level to overflow due to being too high or to run out of water due to being too low, which will affect the birds' drinking experience.
[0004] Water quality is easily polluted: Without a rainwater filtration system, direct use of rainwater may cause impurities, leaves, and other debris to enter the water trough, polluting the water source and breeding bacteria, which can harm the health of birds. Utility Model Content
[0005] The purpose of this invention is to provide a ceramic bird feeder that can collect rainwater. Through a rainwater collection and filtration system, a buoyancy water level adjustment mechanism, and an environmentally friendly material design, it solves the problems of water waste, lack of automatic adjustment in the feeding system, and easy water pollution in existing bird feeders. It realizes the utilization of rainwater resources, intelligent control of water volume, and water quality safety, significantly improving the practicality, environmental protection, and bird health protection capabilities of the bird feeder. It is especially suitable for ecological landscapes and bird protection scenarios in rainy areas.
[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include: A ceramic bird feeder that collects rainwater includes: A base is provided, with a central support column fixedly connected to the center of the top of the base. A water collection tank for rainwater collection is fixedly connected to the top of the central support column. A water feeding trough for feeding water is installed at the edge of the top of the base, corresponding to the position of the water collection tank. A water outlet assembly is installed at the bottom of the water collection tank, corresponding to the position of the water feeding trough.
[0007] The aforementioned ceramic bird feeder that can collect rainwater has a filter frame on the top of the water collection tank, and a filter screen for rainwater filtration is provided on the inner wall of the filter frame.
[0008] The aforementioned ceramic bird feeder that can collect rainwater includes a water outlet component comprising an automatically opening and closing water outlet pipe, which is fixedly connected to the bottom of the water collection tank.
[0009] In the aforementioned ceramic bird feeder that can collect rainwater, a sealing ring is fixedly connected to the inner wall of the water outlet pipe, and a liftable sealing plate is provided at the bottom of the sealing ring.
[0010] In the aforementioned ceramic bird feeder that can collect rainwater, a connecting rod is fixedly connected to the bottom of the sealing ring, a mounting rod is fixedly connected to the bottom of the connecting rod, and a float is fixedly connected to the mounting rod.
[0011] In the aforementioned ceramic bird feeder that can collect rainwater, a sealing gasket matching the sealing ring is fixedly connected to the top of the sealing plate, and the top of the sealing plate is sealed to the bottom of the sealing ring through the sealing gasket.
[0012] In the aforementioned ceramic bird feeder that can collect rainwater, both sides of the bottom of the sealing ring are fixedly connected to a limiting slide rod, and a limiting slide sleeve is slidably connected to the limiting slide rod. The side of the limiting slide sleeve near the sealing plate is fixedly connected to the side of the sealing plate.
[0013] This utility model has at least the following beneficial effects: 1. This utility model realizes a ceramic bird feeder that can collect rainwater. Through the rainwater collection and filtration system, buoyancy water level adjustment mechanism and environmentally friendly material design, it solves the problems of water waste, lack of automatic adjustment of water feeding system and easy water pollution in existing bird feeders. It realizes rainwater resource utilization, intelligent water volume control and water quality safety guarantee, significantly improves the practicality, environmental protection and bird health protection capabilities of bird feeders, and is especially suitable for ecological landscapes and bird protection scenarios in rainy areas.
[0014] 2. Rainwater resource utilization, reducing manual maintenance costs: Natural rainwater is collected through a collection tank, and the top filter screen intercepts impurities such as leaves and dust to ensure clean rainwater; the collected rainwater automatically flows into the water supply tank through the outlet pipe, eliminating the need for frequent manual watering, which is especially suitable for rainy areas and significantly reduces maintenance frequency and water consumption.
[0015] 3. Automatic water level regulation to prevent overflow or water shortage: When the water level in the feeding trough rises, the float ring, under buoyancy, moves the sealing plate upwards via a connecting rod, blocking the sealing ring on the inner wall of the outlet pipe and stopping the water supply; when the water level drops, the weight of the float ring causes the sealing plate to move downwards, restoring the water supply. This mechanism achieves dynamic water balance, preventing overflow from polluting the environment or water shortages from affecting birds' drinking water. Attached Figure Description

Detailed Implementation
[0018] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0019] Please refer to Figures 1 to 3 As shown in the figure, an embodiment of the present invention provides a ceramic bird feeder that can collect rainwater, comprising: a base 1, a central support column 2 fixedly connected to the center of the top of the base 1, a water collection tank 3 for collecting rainwater fixedly connected to the top of the central support column 2, a water feeding trough 4 for feeding water installed at the edge of the top of the base 1 and corresponding to the position of the water collection tank 3, and a water outlet component 5 installed at the bottom of the water collection tank 3 and corresponding to the position of the water feeding trough 4. By adopting the above technical solution, the rainwater collection tank 3 integrates rainwater collection function and top filter screen 3011 to achieve efficient rainwater filtration and avoid impurities from polluting the water quality. Utilizing the buoyancy generated by the float ring 5032 as the water level in the feeding trough 4 rises and falls, the connecting rod 503 links with the sealing plate 5021, allowing it to precisely engage or disengage from the sealing ring 502 on the inner wall of the outlet pipe 501, dynamically adjusting the water flow and achieving automatic water balance. At the same time, the corrosion resistance of the ceramic material and the modular structural design take into account both equipment durability and ease of maintenance, ultimately achieving a triple effect of rainwater resource utilization, intelligent control of water supply, and water quality safety assurance. This significantly reduces manual maintenance costs, improves the drinking health of birds and the environmental value of bird feeders, and is especially suitable for ecological application scenarios in rainy areas.
[0020] In order to achieve preliminary filtration and impurity interception of rainwater, in this embodiment: a filter frame 301 is provided on the top of the water collection tank 3, and a filter screen 3011 for rainwater filtration is provided on the inner wall of the filter frame 301. The filter screen 3011 can intercept large particles of impurities such as leaves and dust, prevent them from entering the water collection tank 3 and polluting the water quality, ensure the cleanliness of the collected rainwater, extend the service life of the water in the water supply trough 4, and reduce the frequency of manual cleaning.
[0021] To achieve automatic discharge and controllable flow of rainwater, in this embodiment: the water outlet component 5 includes an automatically opening and closing water outlet pipe 501, which is fixedly connected to the bottom of the water collection tank 3. A sealing ring 502 is fixedly connected to the inner wall of the water outlet pipe 501, and a liftable sealing plate 5021 is provided at the bottom of the sealing ring 502. The water outlet pipe 501 serves as a rainwater conveying channel, and the design of the bottom sealing ring 502 and sealing plate 5021 provides a structural basis for subsequent control of water flow opening and closing by buoyancy, thereby realizing dynamic adjustment of water supply.
[0022] To achieve the automatic opening and closing function driven by the water level, in this embodiment: a connecting rod 503 is fixedly connected to the bottom of the sealing ring 502, an installation rod 5031 is fixedly connected to the bottom of the connecting rod 503, and a float ring 5032 is fixedly connected to the installation rod 5031. The float ring 5032 generates buoyancy or gravity as the water level in the water tank 4 rises and falls. Through the linkage of the connecting rod 503 with the sealing plate 5021, the automatic opening and closing of the water outlet pipe 501 is achieved without the need for electricity or manual intervention, ensuring the balance of water supply and water level.
[0023] To enhance the sealing effect and prevent water leakage, in this embodiment: a sealing gasket 5022 matching the sealing ring 502 is fixedly connected to the top of the sealing plate 5021, and the top of the sealing plate 5021 is sealed to the bottom of the sealing ring 502 through the sealing gasket 5022. The sealing gasket 5022 is made of a flexible material such as rubber, which fits the surface of the sealing ring 502, fills the gap, prevents rainwater leakage, ensures water level control accuracy, and avoids abnormal water supply due to water leakage.
[0024] To ensure the stable lifting and precise positioning of the sealing plate 5021, in this embodiment: limiting slide rods 504 are fixedly connected to both sides of the bottom of the sealing ring 502, and limiting sleeves 5041 are slidably connected to the limiting slide rods 504. The side of the limiting sleeve 5041 closest to the sealing plate 5021 is fixedly connected to the side of the sealing plate 5021. The limiting slide rods 504 and the limiting sleeves 5041 constitute a guiding mechanism, restricting the sealing plate 5021 to move only in the vertical direction, avoiding skewness or jamming, ensuring the precise alignment of the sealing plate 5021 and the sealing ring 502, and improving the reliability of water level control.
[0025] The working principle of this utility model is as follows: Through a rainwater harvesting and intelligent water level control system, automated rainwater recycling and utilization are achieved. 1. Rainwater collection and filtration: The filter screen 3011 inside the top filter frame 301 of the water collection tank 3 intercepts impurities such as leaves and dust, ensuring that the collected rainwater is clean and unpolluted, and preventing impurities from clogging the outlet pipe 501 or polluting the water quality of the water feeding trough 4.
[0026] 2. Water level driven automatic water supply: The collected rainwater flows into the water supply tank 4 through the outlet pipe 501. When the water level in the water supply tank 4 rises, the float ring 5032 is driven by buoyancy to move the sealing plate 5021 upward through the connecting rod 503. The sealing gasket 5022 on the top of the sealing plate 5021 tightly fits the sealing ring 502 on the inner wall of the outlet pipe 501, blocking the water flow. When the water level drops, the weight of the float ring 5032 causes the sealing plate 5021 to move downward, disengaging from the sealing ring 502, and restoring the water supply.
[0027] 3. Stable lifting and precise sealing: The limit slide bar 504 and the limit slide sleeve 5041 ensure that the sealing plate 5021 moves smoothly in the vertical direction, avoiding deviation that could lead to sealing failure, and ensuring the accuracy and reliability of water level control.
[0028] Through the above design, this utility model achieves zero-energy recovery of rainwater resources, dynamic balance of water supply, and water quality safety assurance, significantly reducing manual maintenance costs, improving the drinking health of birds and the environmental protection and practicality of bird feeders, and is especially suitable for ecological bird protection scenarios in rainy areas.
