Description

Technical Field

[0001] The invention relates to the technical field of gardening supplies, in particular to a double-layer planting box structure and a preparation method thereof. Background Art

[0002] Flower pots are pot-shaped objects used in landscape engineering, and are mainly used in private gardens, villas, community greening and other places. Currently, the flower pots, fruit and vegetable pots, landscape pots and other planting pots on the market are all single-walled pots, and then a water basin is placed at the bottom to prevent water from seeping out and dirtying the ground. However, this traditional planting pot has the following serious defects:

[0003] 1. Because the excess water of the traditional planting pot will leak from the bottom, the soil around the pot is exposed to light and the temperature is high, the water evaporates violently, and frequent watering is not conducive to the respiration of the plant roots and affects the growth of the plants;

[0004] 2. When watering, the remaining water will leak out with dirt and stay in the water tray, which not only affects the appearance, but also easily breeds bacteria and mosquitoes, and also brings trouble to frequent cleaning;

[0005] 3. When watering, a large amount of water will carry the fertilizer in the soil and seep to the bottom of the planting pot or leak out, resulting in a large loss of fertilizer effect;

[0006] 4. When watering traditional planting pots, water often accumulates in the upper part and then quickly flows down along the large gaps in the soil. This not only easily causes the surface soil to become hardened and affect the breathing of plants, but also many places in the middle and lower soil may not absorb water completely and leak out, resulting in uneven soil moisture.

[0011] As a preferred technical solution of the present invention, a lifting step is provided at the top of the outer sidewall, and the four sides of the lifting step are all arc-shaped.

[0012] As a preferred technical solution of the present invention, connection holes are provided inside the four corners of the lifting step for connecting two or more planting box bodies or fixing a plant climbing frame or facilitating fixing the planting box body on a three-dimensional planting rack.

[0013] As a preferred technical solution of the present invention, a groove is jointly provided at the top of the inner sidewall and the outer sidewall, and a water injection hole communicating with the inside of the water storage cavity is provided inside the groove.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention

[0036] Please refer to Figures 1-9 , a double - layer planting box structure and its preparation method, including a planting box main body 1, the planting box main body 1 includes an inner side wall 11, an outer side wall 12 and a water storage cavity 13 arranged between the inner side wall 11 and the outer side wall 12, and a plurality of capillary water seepage holes 14 are arranged on the inner side wall 11

[0037] As a specific technical solution of this embodiment, a plurality of the capillary water seepage holes 14 are distributed on the bottom surface and the side wall of the inner side wall 11, and the diameter of the capillary water seepage holes 14 is less than 0.3 mm

[0038] In this implementation scheme, by limiting the diameter of the capillary water seepage holes 14 to be less than 0.3 mm (such as 0.1 mm - 0.25 mm), the capillary phenomenon is used to realize the slow and uniform infiltration of the water in the water storage cavity 13 into the soil, avoiding the soil drying and fertilizer loss caused by the rapid drainage of traditional planting pots due to gravity. At the same time, the hole distribution on the bottom surface and the side wall of the inner side wall 11 ensures that the water infiltrates the soil from multiple directions, solving the problems of "upper - layer water accumulation and caking, and lower - layer uneven water absorption" of traditional pots

[0039] As a specific technical solution of this embodiment, a number of criss - cross wall surface reinforcing ribs 15 are correspondingly arranged at the bottoms of the inner side wall 11 and the outer side wall 12, and the wall surface reinforcing ribs 15 are segmented and arc - shaped and deepened towards the water storage cavity 13

[0040] In this implementation scheme, the criss-cross arch-shaped wall strengthening ribs 15 significantly improve the load-bearing capacity of the double-layer wall, preventing the inner and outer walls from deforming or collapsing due to the pressure of the soil weight. It is especially suitable for scenarios of planting large plants or having thick soil layers. The arch-shaped 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 main body 1.

[0041] As a specific technical solution of this embodiment, the intersection of two adjacent sections of the wall strengthening ribs 15 has the deepest depression. The positions of the intersection points of the wall strengthening ribs 15 on the inner wall 11 and the outer wall 12 correspond to each other and are connected to form the inner and outer wall support points 16 on the bottom surface.

[0042] In this implementation scheme, the connection design of the inner and outer wall support points 16 at the intersection of the wall strengthening ribs 15 on the inner wall 11 and the outer wall 12 forms a three-dimensional network support structure, enhancing the compressive performance at the bottom of the double-layer wall, avoiding the water storage cavity 13 from leaking due to long-term pressure rupture. At the same time, the inner and outer wall support points 16 on the bottom surface limit the relative displacement of the inner wall 11 and the outer wall 12, ensuring the stable position of the capillary water seepage holes 14 and maintaining the uniformity of water seepage.

[0043] As a specific technical solution of this embodiment, a circle of lifting steps 17 is provided at the top of the outer wall 12, and the four sides of the lifting steps 17 are all arc-shaped.

[0044] In this implementation scheme, the arc-shaped concave lifting steps 17 at the top of the outer wall 12 provide an ergonomic gripping position, facilitating the handling of the planting box main body 1. The four-side arc-shaped concave design avoids hand bumps during handling and at the same time adapts to the grasping requirements in narrow spaces, such as when placed against a wall.

[0045] As a specific technical solution of this embodiment, connection holes 171 are provided inside the four corners of the lifting steps 17 for connecting two or more planting box main bodies 1 or fixing a plant climbing frame or for conveniently fixing the planting box main body 1 on a three-dimensional planting rack.

[0046] In this implementation scheme, the four-corner connection holes 171 support modular expansion:

[0047] Pairwise connection: Refer to Figure 6 , two planting box main bodies 1 are stacked vertically one above the other. A through hole is provided inside the upper planting box main body 1, which can increase the soil layer thickness and facilitate the planting of deep-rooted plants. The two planting box main bodies 1 are fixed by passing screws through the connection holes 171. Water is injected into the interior of the upper planting box main body 1 around the through hole. The water inside the upper planting box main body 1 can flow into the water storage cavity 13 of the lower planting box main body 1 through the grooves 18 and the water injection holes 181. After the two planting box main bodies 1 are locked with screws, a seal is maintained between the two planting box main bodies 1;

[0048] Climbing frame fixation: The plant climbing frame can be inserted through the connection hole 171 for planting twining climbing plants, avoiding the inconvenience of the need for additional drilling in traditional flower pots.

[0049] Quick disassembly and assembly: The screw connection method facilitates layout adjustment or disassembly and cleaning.

[0050] As a specific technical solution of this embodiment, a circular groove 18 is jointly arranged at the tops of the inner side wall 11 and the outer side wall 12, and a water injection hole 181 communicating with the inside of the water storage cavity 13 is arranged inside the groove 18.

[0051] In this implementation scheme, the integrated design of the top groove 18 and the water injection hole 181 realizes convenient water injection. The water injection hole 181 is directly connected to the water storage cavity 13, avoiding the trouble of frequent dumping of the traditional water receiving tray. The groove 18 can also collect rainwater or irrigation surplus water and flow back to the water storage cavity 13 through the water injection hole 181, improving the utilization rate of water resources.

[0052] As a specific technical solution of this embodiment, a plurality of side wall reinforcing ribs 19 are arranged on the side wall of the inner side wall 11, and a water leakage hole 3 is also arranged 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 hole plug 31 is movably inserted at the bottom of the water leakage hole 3.

[0053] In this implementation scheme, the side wall reinforcing ribs 19 enhance the anti-lateral extrusion ability of the inner side wall 11, prevent the wall body from cracking due to soil swelling or root growth, and at the same time assist in positioning the capillary water seepage holes 14 to avoid blocking the water seepage channels due to wall surface deformation.

[0054] A preparation method for a double-layer planting box structure includes the following steps:

[0055] S1. Forming a double-layer wall hollow structure, integrally forming the inner side wall 11, the outer side wall 12 and the water storage cavity 13 therebetween by plastic blow molding process; or separately manufacturing the inner side wall 11 and the outer side wall 12 and then forming a closed double-layer wall hollow structure through a splicing process;

[0056] S2. Processing capillary water seepage micropores, processing capillary water seepage holes 14 with a diameter less than 0.3 mm on the bottom surface and the side wall seepage area of the inner side wall 11 by laser cutting process or hot melt perforation process;

[0057] S3. Setting water injection holes, opening water injection holes 181 at the top groove 18 of the planting box main body 1 or on the outer side wall;

[0058] S4. Manufacturing the box body strengthening structure, setting a lifting step 17 with an arc-shaped concave inner side on the top of the outer side wall 12 main body during injection molding, arranging side wall reinforcing ribs 19 on the inner side wall 11, and arranging a plurality of arch-shaped wall surface reinforcing ribs 15 that are criss-crossed and deepened in the direction of the cavity depth on the bottom surfaces of the inner side wall 11 and the outer side wall 12;

[0059] S5. Set multi-functional connection holes. Connection holes 171 are provided inside the four corners of the lifting step 17 for connecting two or more planter bodies 1 or fixing plant climbing frames, or for conveniently fixing the planter body 1 on a three-dimensional planter rack.

[0060] S6. Set water leakage holes. Water leakage holes 3 that are not connected to the inside of the water storage cavity 13 are provided between the inner side wall 11 and the outer side wall 12 to prevent water accumulation inside the planter body 1 in rainy outdoor environments. There is a hole plug 31, which can be used to block the holes when it is not necessary to place it outdoors.

[0061] The planter body 1 preferably adopts a blow molding process. The blow molding integral forming process ensures that the water storage cavity 13 between the inner and outer walls is completely sealed without splicing gaps, and the air blowing port after blow molding can be directly used as the water injection hole 181, which simplifies the production process and reduces costs.

[0062] 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 optional item when heating is required to control the water temperature. In S3, a water pipe interface is configured at the outer end of the water injection hole 181 as an optional item when automatic water replenishment is required to connect to an external water supply device.

[0063] In this implementation scheme, refer to Figure 7 , an electric heating device 2 is arranged inside the water storage cavity 13. The electric heating device 2 adopts an electric heating wire or an electric heating tube. The power connection end of the electric heating device 2 is connected to a wire that passes through the water injection port or the groove and is connected to a temperature controller. The soil temperature is adjusted by the water temperature to meet the growth requirements of plants in cold regions or tropical regions. A water level sensor is arranged inside the water storage cavity 13, and the water injection hole 181 is externally connected to a water pipe to achieve automatic water replenishment, achieving the effect of "no manual watering, constant temperature and humidity".

[0064] In summary, for this double-layer planter structure and its preparation method, through the double-layer wall water storage cavity 13 and the capillary water seepage holes 14, the capillary phenomenon is used to slowly and evenly moisten the soil, solving the problems of frequent watering, soil compaction, and uneven humidity caused by gravity drainage in traditional planters. The closed design of the water storage cavity 13 makes the water and fertilizer almost zero loss, reducing fertilizer waste and avoiding the breeding of bacteria and mosquitoes in the water receiving tray. The wall strengthening ribs 15 and the inner and outer wall support points 16 on the bottom surface enhance the load-bearing capacity, adapting to the planting requirements of thick soil layers and large plants. The modular connection holes 171 support expansion, stacking, or climbing frame fixation, improving the flexibility of use. The addition of a water pipe and an electric heating device 2 in the water storage cavity 13 can be linked to achieve automatic water replenishment and temperature control, which is applicable to extreme environments such as deserts and cold regions, providing a low-cost and high-benefit solution for modern planting and having broad application prospects.
