Double-layer planting box structure

Abstract

This invention discloses a double-layer planting box structure, relating to the field of horticultural supplies technology. It includes a planting box body comprising an inner wall, an outer wall, and a closed water storage cavity enclosed by them. The inner wall has small holes that allow capillary action, enabling slow and even wetting of the soil placed inside the planting box. The speed and extent of soil wetting can be controlled by adjusting the size, position, and number of these capillary holes. The closed design of the water storage cavity ensures near-zero loss of stored water and dissolved fertilizer. This solves problems associated with traditional planting pots, such as frequent watering, bottom leakage affecting hygiene and fertilizer loss, soil compaction, uneven humidity, and large diurnal temperature variations. Furthermore, the water storage cavity is connected to a water pipe for automatic water replenishment and temperature control. An electric heating device is added inside the water storage cavity for temperature regulation, providing a new solution for automated planting, decentralized home planting, and planting in extreme environments such as deserts and cold regions.

Description

Technical Field

[0001] This invention relates to the field of gardening supplies technology, specifically a double-layer planting box structure. Background Technology

[0002] Flower pots are basin-shaped containers used in landscaping projects, primarily for private gardens, villas, and residential green spaces. Currently, most commercially available planting pots, such as flower pots, fruit and vegetable pots, and landscape pots, are single-walled, with a drip tray at the bottom to prevent water seepage and soiling of the ground. However, this traditional planting pot has the following serious drawbacks:

[0003] 1. Because excess water in traditional planting pots will leak out from the bottom, the soil around the pot is exposed to sunlight and the temperature is high, resulting in a lot of water evaporation. Frequent watering is not conducive to the respiration of plant roots and affects the growth of plants.

[0004] 2. When watering, the remaining water, along with soil and dirt, leaks out and stays in the drip tray, which not only affects the appearance but also easily breeds bacteria and insects, and makes it troublesome to clean frequently.

[0005] 3. Because when watering, a large amount of water carries fertilizer from the soil and seeps to the bottom of the planting pot or leaks out, resulting in a significant loss of fertilizer effectiveness.

[0006] 4. In traditional potted plants, water often accumulates at the top and then flows down quickly through the large gaps in the soil. This not only easily causes the top layer of soil to harden and affect plant respiration, but also means that the middle and lower soil may not absorb water completely before it leaks out, resulting in uneven soil moisture. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution: a double-layer planting box structure, comprising a planting box body, the planting box body comprising an inner side wall, an outer side wall, and a water storage cavity disposed between the inner side wall and the outer side wall, wherein the inner side wall is provided with a plurality of capillary permeation holes.

[0008] As a preferred embodiment of the present invention, a plurality of capillary perforations are distributed on the bottom surface and sidewall of the inner wall, and the diameter of the capillary perforations is less than 0.3 mm.

[0009] As a preferred embodiment of the present invention, the bottom of the inner and outer walls are provided with a number of intersecting wall reinforcement ribs, which are segmented and deepened in an arched shape towards the water storage cavity.

[0010] As a preferred embodiment of the present invention, the deepest recess is located at the intersection of two adjacent wall reinforcement ribs, and the intersection points of the wall reinforcement ribs on the inner and outer walls are corresponding and connected to each other to form the bottom inner and outer wall support points.

[0011] As a preferred embodiment of the present invention, a ring of armrest steps is provided at the top of the outer side wall, and the four sides of the armrest steps are all arc-shaped.

[0012] As a preferred embodiment of the present invention, the four corners of the lifting step are provided with connecting holes for connecting or fixing two or more planting box bodies or for conveniently fixing the planting box body to the three-dimensional planting frame.

[0013] As a preferred embodiment of the present invention, the top of the inner sidewall and the outer sidewall are provided with a groove, and the inside of the groove is provided with a water injection hole that communicates with the inside of the water storage cavity.

[0014] As a preferred embodiment of the present invention, the inner sidewall is provided with a plurality of sidewall reinforcing ribs, and a water leakage hole is provided between the inner sidewall and the outer sidewall. The water leakage hole is not connected to the inside of the water storage cavity, and a plug is movably inserted into the bottom of the water leakage hole.

[0015] Compared with the prior art, the present invention provides a double-layer planting box structure, which has the following beneficial effects:

[0016] This double-layer planting box structure utilizes a double-walled water storage chamber and capillary drainage holes to slowly and evenly moisten the soil through capillary action. This solves the problems of frequent watering, soil compaction, and uneven moisture caused by gravity drainage in traditional planting pots. The sealed design of the water storage chamber ensures almost zero water and fertilizer loss, reducing fertilizer waste and preventing bacteria and insects from growing in the drip tray. The reinforced walls and the support structure on the inner and outer walls of the bottom enhance the load-bearing capacity, making it suitable for planting in thick soil layers and large plants. Modular connection holes support expansion and stacking or climbing frame fixation, improving the flexibility of use. The water storage chamber is equipped with water pipes and an electric heating device that can automatically replenish water and regulate temperature. It is suitable for extreme environments such as deserts and cold regions, providing a low-cost, high-efficiency solution for modern planting and has broad application prospects.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-9 A double-layer planting box structure includes a planting box body 1, the planting box body 1 includes an inner side wall 11, an outer side wall 12 and a water storage cavity 13 disposed between the inner side wall 11 and the outer side wall 12, and the inner side wall 11 is provided with a plurality of capillary drainage holes 14.

[0029] As a specific technical solution of this embodiment, a plurality of capillary perforations 14 are distributed on the bottom surface and side wall of the inner sidewall 11, and the diameter of the capillary perforations 14 is less than 0.3 mm.

[0030] In this embodiment, by limiting the diameter of the capillary permeation holes 14 to less than 0.3 mm (e.g., 0.1 mm-0.25 mm), the capillary effect is used to allow water in the water storage chamber 13 to slowly and evenly seep into the soil, avoiding the soil drying and fertilizer loss caused by the rapid drainage due to gravity in traditional planting pots. At the same time, the distribution of holes on the bottom and side walls of the inner wall 11 ensures that water permeates the soil from multiple directions, solving the problem of "water accumulation and hardening in the upper layer and uneven water absorption in the lower layer" in traditional pots.

[0031] As a specific technical solution in this embodiment, the bottom of the inner wall 11 and the outer wall 12 are provided with a number of crisscrossing wall reinforcing ribs 15, and the wall reinforcing ribs 15 are segmented and deepened in an arch shape towards the water storage cavity 13.

[0032] In this implementation scheme, the crisscrossing arched wall reinforcement 15 significantly improves the load-bearing capacity of the double-layer wall, preventing the inner and outer walls from deforming or collapsing due to soil weight pressure. It is especially suitable for planting large plants or thick soil layers. The arched design disperses the pressure borne by the inner wall 11 to the outer wall 12 and its load-bearing points, extending the service life of the planting box body 1.

[0033] As a specific technical solution in this embodiment, the deepest recess is at the intersection of two adjacent wall reinforcing ribs 15, and the intersection of the wall reinforcing ribs 15 on the inner wall 11 and the outer wall 12 corresponds to each other and is connected to form the bottom inner and outer wall support points 16.

[0034] In this embodiment, the bottom inner and outer wall support points 16 at the intersection of the wall reinforcing ribs 15 of the inner wall 11 and the outer wall 12 are connected to form a three-dimensional mesh support structure, which enhances the compressive strength of the bottom of the double-layer wall and prevents the water storage cavity 13 from rupturing and leaking due to long-term pressure. At the same time, the bottom inner and outer wall support points 16 restrict the relative displacement of the inner wall 11 and the outer wall 12, ensuring the stability of the capillary seepage holes 14 and maintaining the uniformity of seepage.

[0035] As a specific technical solution in this embodiment, a ring of armrest steps 17 is provided on the top of the outer wall 12, and the four sides of the armrest steps 17 are all arc-shaped.

[0036] In this embodiment, the arc-shaped concave lifting step 17 at the top of the outer side wall 12 provides an ergonomic grip position, which facilitates the handling of the main body 1 of the planting box. The arc-shaped concave design on all four sides avoids hand bumps during handling, and is also suitable for narrow spaces, such as the gripping needs when placed against a wall.

[0037] As a specific technical solution in this embodiment, the four corners of the lifting step 17 are provided with connection holes 171 for connecting or fixing two or more planting box bodies 1 or for conveniently fixing the planting box body 1 to the three-dimensional planting frame.

[0038] In this implementation scheme, the four corner connection holes 171 support modular expansion:

[0039] Reciprocal connection: See Figure 6 Two planting box bodies 1 are stacked one on top of the other. The upper planting box body 1 has through holes inside to increase the soil layer thickness and facilitate the planting of deep-rooted plants. The two planting box bodies 1 are fixed by screws through the connecting holes 171. Water flows into the interior of the upper planting box body 1 through the through holes. The water inside the upper planting box body 1 can flow into the water storage chamber 13 of the lower planting box body 1 through the grooves 18 and the water injection holes 181. After the screws are tightened, the two planting box bodies 1 are sealed together.

[0040] Climbing frame fixing: A plant climbing frame can be inserted through the connecting hole 171 for planting climbing plants, avoiding the inconvenience of needing to drill extra holes in traditional flower pots;

[0041] Quick assembly and disassembly: The screw connection method facilitates layout adjustment or disassembly for cleaning.

[0042] As a specific technical solution of this embodiment, the top of the inner wall 11 and the outer wall 12 are provided with a groove 18, and the inside of the groove 18 is provided with a water injection hole 181 that communicates with the inside of the water storage cavity 13.

[0043] In this embodiment, the top groove 18 and the water inlet hole 181 are integrated to facilitate water filling. The water inlet hole 181 is directly connected to the water storage chamber 13, avoiding the trouble of frequent emptying of traditional water receiving trays. The groove 18 can also collect rainwater or irrigation waste water, which flows back to the water storage chamber 13 through the water inlet hole 181, thereby improving water resource utilization.

[0044] As a specific technical solution of this embodiment, a number of side wall reinforcing ribs 19 are provided on the side wall of the inner side wall 11, and a water leakage hole 3 is provided between the inner side wall 11 and the outer side wall 12. The water leakage hole 3 is not connected to the inside of the water storage cavity 13, and a plug 31 is movably inserted into the bottom of the water leakage hole 3.

[0045] In this embodiment, the side wall reinforcing ribs 19 enhance the lateral compression resistance of the inner side wall 11, preventing the wall from cracking due to soil expansion or root growth. At the same time, they assist in the positioning of the capillary seepage holes 14, preventing the seepage channels from being blocked due to wall deformation.

[0046] A method for preparing a double-layer planting box structure includes the following steps:

[0047] S1. The double-walled hollow structure is formed by integrally molding the inner wall 11, the outer wall 12 and the water storage cavity 13 between them using plastic blow molding process; or the inner wall 11 and the outer wall 12 are manufactured separately and then spliced ​​together to form a closed double-walled hollow structure.

[0048] S2. Capillary permeation micropore processing: Capillary permeation holes 14 with a diameter of less than 0.3 mm are processed on the bottom surface and the permeation area of ​​the inner wall 11 using laser cutting or hot melt perforation process.

[0049] S3. Set up water injection holes by opening water injection holes 181 in the groove 18 at the top of the main body 1 of the planting box or on the outer wall.

[0050] S4. Box reinforcement structure manufacturing: During injection molding, a raised arm step 17 with four sides concave in an arc shape is set on the top of the outer wall 12 main body, and a side wall reinforcing rib 19 is set on the inner wall 11. Several crisscrossing arched wall reinforcing ribs 15 that deepen in the direction of cavity depth are set on the bottom surface of the inner wall 11 and the outer wall 12.

[0051] S5. Set up multi-functional connection holes. Connection holes 171 are set inside the four corners of the lifting step 17 for connecting or fixing two or more planting box bodies 1 or for conveniently fixing the planting box body 1 to the three-dimensional planting frame.

[0052] S6. A drainage hole is provided between the inner wall 11 and the outer wall 12. The drainage hole 3 is not connected to the inside of the water storage cavity 13 to prevent water from accumulating inside the planting box body 1 in outdoor rainy weather. There is a hole plug 31, which can be used to block the hole when it is not needed to be placed outdoors.

[0053] The main body 1 of the planting box is preferably made by blow molding. The blow molding process ensures that the water storage cavity 13 between the inner and outer walls is completely sealed without any splicing gaps. After blow molding, the air inlet can be directly used as the water injection hole 181, which simplifies the production process and reduces costs.

[0054] As a specific technical solution of this embodiment, in S1, an electric heating device 2 is arranged inside the water storage cavity 13 as an option when heating is required, for controlling the water temperature. In S3, a water pipe interface is configured at the outer end of the water injection hole 181 as an option when automatic water replenishment is required, for connecting to an external water supply device.

[0055] In this implementation plan, please refer to Figure 7 The water storage chamber 13 has a built-in electric heating device 2, which uses an electric heating wire or an electric heating tube. The electric heating device 2 is connected to a thermostat by a wire that passes through the water inlet or groove. The soil temperature is adjusted by the water temperature to meet the growth needs of plants in cold or tropical regions. A water level sensor is installed inside the water storage chamber 13. The water inlet 181 is connected to an external water pipe to achieve automatic water replenishment, thus achieving the effect of "no manual watering and constant temperature and humidity".

[0056] In summary, this double-layer planting box structure, through the double-walled water storage chamber 13 and capillary drainage holes 14, utilizes capillary action to slowly and evenly moisten the soil, solving the problems of frequent watering, soil compaction, and uneven moisture caused by gravity drainage in traditional planting pots. The closed design of the water storage chamber 13 ensures almost zero water and fertilizer loss, reducing fertilizer waste and preventing bacteria and insects from growing in the drip tray. The wall reinforcement ribs 15 and the bottom inner and outer wall support points 16 enhance the load-bearing capacity, adapting to the needs of thick soil layers and large plant planting. The modular connection holes 171 support expansion and stacking or climbing frame fixation, improving the flexibility of use. The water storage chamber 13 is equipped with water pipes and an electric heating device 2 for automatic water replenishment and temperature control, making it suitable for extreme environments such as deserts and cold regions. It provides a low-cost, high-efficiency solution for modern planting and has broad application prospects.
