[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0037] See Figures 1 to 6 As shown;
[0038] This embodiment discloses a water-connected, waterless flowerpot, which includes:
[0039] Flowerpot outer cylinder 1 and flowerpot inner cylinder 2 placed inside flowerpot outer cylinder 1;
[0040] The space between the outer cylinder 1 and the inner cylinder 2 of the flowerpot is configured as a water storage space 103, and a drainage structure is provided between the water storage space 103 and the inner cylinder 2 of the flowerpot to drain the water in the water storage space 103 to the inner cylinder 2 of the flowerpot through the drainage structure.
[0041] The outer cylinder 1 of the flowerpot is provided with a water inlet 101, through which water is injected into the water storage space 103;
[0042] The water inlets 101 between adjacent flowerpots are connected by a plastic hose 502 to keep the water level in the water storage space 103 of the two adjacent flowerpots consistent.
[0043] Specifically, this embodiment discloses a novel flowerpot structure that can be used individually or multiple flowerpots can be connected in series via the aforementioned plastic flexible tube 502. Firstly, the flowerpot in this embodiment includes an outer pot 1 and an inner pot 2. The space between the outer pot 1 and the inner pot 2 serves as a water storage space 103, storing a certain amount of water. Water is continuously replenished to the inner pot 2 through a drainage structure, ensuring sufficient water for plant growth without overwatering. Furthermore, if multiple flowerpots are connected in series, the water inlets 101 between the flowerpots can be connected together using the plastic flexible tube 502. Utilizing the principle of communicating vessels, this ensures that the water level in the water storage space 103 of each flowerpot is consistent, achieving the effect of synchronized water levels in all flowerpots when watering one flowerpot. Additionally, the external water level must be higher than the inlet for excess water to flow into other flowerpots through the water inlet 101.
[0044] Preferably, in this embodiment, the lower part of the flowerpot outer cylinder 1 is a base 104 with a height of 30mm, and the flowerpot outer cylinder 1 maintains a certain distance from the ground through the base 104, which enhances stability and breathability; the center of the flowerpot outer cylinder 1 protrudes upward to form a protrusion 105, and the protrusion 105 extends into the interior of the flowerpot inner cylinder 2; the part of the protrusion 105 extending into the interior of the flowerpot inner cylinder 2 has a vent hole 106 communicating with the outside, and the opening size of the vent hole 106 is φ3mm, and the part of the protrusion 105 extending into the water storage space 103 has a non-porous structure; air enters the interior of the protrusion 105 through the bottom of the flowerpot outer cylinder 1 and enters the flowerpot inner cylinder 2 through the vent hole 106.
[0045] To prevent root rot caused by lack of oxygen or dampness, this embodiment first uses the base 104 to raise the flowerpot as a whole away from the ground, and uses the protrusion 105 to supply air into the inner cylinder 2 of the flowerpot to ensure sufficient oxygen for plant growth.
[0046] To further collect water resources, especially rainwater, the upper end of the outer tube 1 of the flowerpot in this embodiment is a flowerpot ring platform 3, and the upper surface of the flowerpot ring platform 3 is configured as a slope 301 extending downward toward the inner tube 2 of the flowerpot. A 5mm wide gap is reserved between the slope 301 and the inner tube 2 of the flowerpot, which serves as a rainwater collection port 302. Additionally, this embodiment can be equipped with a removable filter screen with a 2mm mesh size. This ensures smooth drainage and prevents water accumulation even with a rainfall of 50mm / h.
[0047] The small-slit rainwater collection inlet 302, used as a linear drain outlet, effectively prevents impurities from flowing in and avoids clogging. Furthermore, the combination of the slope and the rainwater collection inlet helps collect rainwater, conserving water resources.
[0048] Preferably, in this embodiment, the drainage structure uses a 5mm diameter degreased cotton rope / water-guiding thread. One end of the degreased cotton rope / water-guiding thread extends to the bottom of the water storage space 103 and connects to a counterweight at the bottom of the water storage space 103. The other end of the water-guiding thread passes through the inner cylinder 2 of the flowerpot and extends to the bottom of the inner cylinder 2. By continuously channeling water from the water storage space 103 into the inner cylinder 2 of the flowerpot using the water-guiding thread 4, water can be continuously replenished into the inner cylinder 2 of the flowerpot.
[0049] When the flowerpot is used alone or multiple flowerpots are connected in series, the water inlet 101 without the plastic hose 502 and the water inlet 101 after watering is completed when used alone can be sealed with the plastic plug 501.
[0050] In a preferred embodiment, the outer cylinder 1 of the flowerpot is configured as a quadrilateral conical structure, and the cross-sectional dimensions of the outer cylinder 1 gradually decrease from top to bottom; each of the four sides of the outer cylinder 1 is provided with a water inlet 101. Furthermore, to make the outer wall design more aesthetically pleasing and practical, the outer cylinder 1 is made into a V-shaped groove, which allows water to be automatically drained through the water guide channel 102 in case of rain or flooding, preventing dust and soil on the surface of the flowerpot from affecting its appearance.
[0051] Finally, in this embodiment, the outer tube 1 of the flowerpot is made of food-grade PP material, which has good corrosion resistance and stability; it is recommended to place expanded clay pebbles at the bottom of the inner tube 2 of the flowerpot to facilitate root respiration. The two are connected by snap-fit, making installation convenient and secure.
[0052] The waterless flowerpot in this embodiment has two working modes:
[0053] First mode: Single pot mode
[0054] 1. Water filling: Fill the water storage space 103 with water through the water inlet 101. Pay attention to the water level when filling the water to avoid overflowing. It is advisable to fill the water storage space 103 to 90% full.
[0055] 2. Water Supply: Water in the water storage space 103 is continuously and slowly transported to the inner cylinder 2 of the flowerpot through the capillary action of the water-conducting cotton thread 4, providing moisture to the plant roots. The water-conducting cotton thread 4 absorbs 50-80 ml of water per hour, which can be adjusted according to the plant's water needs.
[0056] 3. Rainwater Collection: Rainwater falls onto the slope 301 and flows into the water storage space 103 through the rainwater collection inlet 302, achieving effective collection and utilization of water resources. During the collection process, the filter screen needs to be cleaned regularly to prevent debris from clogging it; it is recommended to clean it once a month.
[0057] The second mode: multi-pot mode
[0058] 1. Watering: Pour water into any pot through water inlet 101. The water level should be higher than the water inlet of the flowerpot. Alternatively, you can connect a tap water pipe to ensure a steady water flow.
[0059] 2. Water level equalization: Water flows through the quick-connect plastic hose 502 with a sealing ring and is distributed among the flower pots. Using the principle of communicating vessels, the water level of the group of flower pots is automatically balanced.
[0060] 3. Independent water supply: Each flowerpot independently draws water from the water storage space 103 through its own water-conducting cotton thread 4 to supply water to the plants.
[0061] In the above technical solution, the water-connected, waterless flowerpot provided by this utility model has the following beneficial effects:
[0062] The purpose of this invention is to provide a water-connected, waterless flowerpot, which aims to reduce the frequency of watering and build an efficient water storage and supply system; create a stable growth environment for the roots and reduce the risk of root rot; its unique appearance design makes the flowerpot both practical and ornamental; it can be used for seedling cultivation and mass production in the agricultural and forestry industries, and is suitable for various indoor and outdoor environments; it can effectively collect and utilize rainwater, reduce water waste, and conform to the concept of ecological and environmental protection.
[0063] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
