Description

Technical Field

[0001] This utility model relates to the field of cultivation box technology, specifically to a rotationally molded rainwater siphon-type greening cultivation box. Background Technology

[0002] Traditional urban landscaping typically involves planting flowers and trees directly in flower beds, pots, or green spaces without rainwater harvesting and storage systems. Rainwater quickly runs off or evaporates after it falls, leaving the city reliant on artificial irrigation during dry seasons, consuming enormous amounts of urban water. During the rainy season, the inability to retain surface runoff leads to direct runoff, becoming a significant contributing factor to urban flooding.

[0003] Current cultivation containers generally suffer from simple structure and limited function, making them ineffective at collecting and storing rainwater. To address this issue, existing technologies, such as patent document CN204157348U, disclose a rainwater harvesting and storage water-saving tank for urban landscaping. This water-saving tank includes a flower bed enclosure, with the enclosed area divided into a water storage zone and a cultivation zone. Several of these water-saving tanks are placed within the water storage zone, and both the tanks and the cultivation zone are filled with a cultivation substrate, where plants are planted. Therefore, during rainfall, the rainwater harvesting and storage flower bed can collect rainwater and store it in the water-saving tank; during dry seasons, water slowly seeps into the plant root zone through capillary action for use, or the plant roots directly absorb water from the water-saving tank, similar to hydroponics.

[0004] Although the aforementioned patent documents disclose a solution to the problem of effectively collecting and storing rainwater, their application still has limitations, as follows:

[0005] Because water slowly seeps into the plant root zone through capillary action for use, this continuous water supply cannot be adjusted according to the plant's actual water requirements, easily leading to water waste or insufficient supply. During seasons when plant demand is low and the weather is humid, this continuous water supply not only causes the soil to become overly wet, affecting root respiration and potentially triggering diseases, but also rapidly reduces water storage areas, thus impacting overall water retention.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] This utility model provides a rotationally molded rainwater collection siphon type greening cultivation box, which aims to solve the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rotationally molded rainwater siphon-type greening cultivation box, comprising a first box body, a first basin body, a second box body, and a second basin body. The height of the second box body is less than the height of the first box body and is located on the top side of the first box body. The adjacent side walls of the second box body and the first box body are connected. The first basin body is correspondingly located in the box opening facing upwards in the first box body, and the second basin body is correspondingly located in the box opening facing upwards in the second box body. The bottom of the first box body and the bottom of the second box body both serve as water storage parts for rainwater. When the bottoms of the first box body and the second box body both store rainwater, the bottom of the first basin body and the bottom of the second basin body are both higher than or equal to the water surface of the rainwater. It also includes a water absorption structure, which has an intake end and a release end. The intake end is located at the bottom of the first box body and the second box body and is submerged in rainwater. The release end is located in the first basin body and the second basin body. The water absorption structure is configured to siphon rainwater from bottom to top to the release end through the intake end.

[0009] The relevant content in the above plan is explained as follows:

[0010] In the above scheme, the connection between the adjacent side walls of the two boxes means that the rainwater collected by the first box and the second box can be shared.

[0011] In the above scheme, the bottom of the first box and the bottom of the second box both include the bottom and the bottom perimeter, which means that rainwater will not only accumulate at the bottom but also at the bottom perimeter, for example, at the connection between the adjacent side walls of the two boxes.

[0012] In the above scheme, the bottom of the first pot and the bottom of the second pot are both higher than or equal to the water level of the rainwater, which means that the roots of the green plants in the first pot and the second pot will not be soaked by rainwater, reducing the risk of root rot.

[0013] It should be noted that the bottom of the first basin and the bottom of the second basin may or may not be flush; preferably, they are flush.

[0014] Meanwhile, the water level of rainwater is usually below the bottom of the first and second basins. In special circumstances, such as heavy rain, the water level may exceed the bottom of the first and second basins. In this case, overflow outlets can be set around the first and second basins. When the rainwater exceeds the bottom of the first and second basins, the excess water can be discharged through the overflow outlets.

[0015] In the above scheme, the water-absorbing structure can be made of porous fiber material (such as cotton rope, non-woven fabric, etc.), which is filled with micron-level pores (equivalent to countless capillaries).

[0016] In the above solution, the automatic supply and discharge of water can be achieved through the water-absorbing structure, which can save water resources and prevent root rot of plants. Specifically, plants are placed in the first and second pots, and rainwater is collected inside the first and second boxes. When the soil around the plant roots is short of water, it will absorb a large amount of water from the release end, which will cause water loss at the release end. Then, the rainwater will be siphoned from bottom to top to the release end. The whole process is carried out automatically by the water-absorbing structure, which can save water resources and prevent a large amount of water from entering the soil and causing root rot of plants.

[0017] Unlike existing technologies that continuously supply water, the water in this application is mainly supplied based on the demand at the release end, achieving on-demand supply, avoiding water waste, and ensuring that plants can obtain suitable water under different weather conditions, thereby improving the growth quality and survival rate of plants.

[0018] A further technical solution is that the water-absorbing structure is a water-absorbing cotton strip, which includes a first cotton strip. The first cotton strip automatically siphons rainwater from the water storage part to the release end through capillary force. Multiple first cotton strips are threaded through the bottom of both the first basin and the second basin. All the first cotton strips are perpendicular to the water surface of the rainwater, and the lower end of each first cotton strip is the suction end and the upper end is the release end. The lower end of the first cotton strip threaded through the first basin extends into the bottom of the first box. The lower end of the first cotton strip threaded through the second basin extends into the bottom of the second box.

[0019] The length of the first cotton strip threaded through the second basin is shorter than the length of the first cotton strip threaded through the first basin.

[0020] With the above design, water can be evenly supplied to the second basin by multiple first cotton strips threaded through the second basin; and water can be evenly supplied to the first basin by multiple first cotton strips threaded through the first basin.

[0021] This ensures that the water content is evenly distributed throughout the first and second basins.

[0022] In a further technical solution, the absorbent swab also includes a second swab; when the bottoms of both the first box and the second box contain rainwater, one end of the second swab is located in the rainwater at the bottom of the first box, and the other end passes through the connection between the first box and the second box and penetrates into the interior along the periphery of the second basin; the second swab is used to siphon the rainwater in the first box to the interior area of ​​the second basin through capillary force.

[0023] Since less rainwater collects inside the second chamber, the second basin can be supplied with water via the second cotton swab thanks to the above design.

[0024] In a further technical solution, the bottom side wall of the second box is provided with a second connecting port, the side wall of the first box is provided with a first connecting port, and the second connecting port is connected to the first connecting port; the lowest point of the second connecting port is higher than the inner surface of the bottom of the first box.

[0025] With the above design, rainwater inside the second box can be combined with rainwater inside the first box. When the rainwater is combined, the rainwater accumulated inside the second box is introduced into the first connecting port through the second connecting port, thus accumulating in the first box. After the rainwater accumulates to a certain level at the bottom of the first box (i.e., exceeding the lowest point of the second connecting port), it will enter the second box.

[0026] In a further technical solution, the first box includes a hollow base and a box cover disposed on the hollow base, wherein the length of the box cover is greater than the length of the second box.

[0027] This design guides rainwater to collect within the hollow base, while simultaneously increasing the load-bearing area at the bottom of the enclosure. When the second enclosure is full of water, it prevents the enclosure from becoming top-heavy due to insufficient load-bearing area at the bottom, thus avoiding tilting and tipping over.

[0028] A further technical solution is that the first box and the first basin are integrally formed by rotational molding to form a first component, and the second box and the second basin are integrally formed by rotational molding to form a second component; the first component and the second component are interconnected and the first box and the second box are connected at a predetermined position; both the first basin and the second basin are provided with multiple reserved holes to guide the release end of the water absorption structure into the corresponding basin and position it.

[0029] The above design significantly improves manufacturing efficiency. Specifically, when the first housing and the first basin, and the second housing and the second basin are integrally molded into the first and second components using rotational molding, the number of separate assembly steps can be greatly reduced, eliminating the time consumption and sealing risks associated with welding or splicing multiple parts, thereby effectively reducing overall production costs. Furthermore, the first and second components can be precisely connected at predetermined positions, ensuring seamless alignment of the interfaces between the two housings; simultaneously, multiple pre-drilled holes on the two basins precisely position the release end of the absorbent structure, effectively preventing assembly misalignment and ensuring the reliable deployment of key functional components such as the absorbent core and water guide pipe.

[0035] The working principle and advantages of this utility model are as follows:

[0036] This invention enables automatic water supply and drainage through a water-absorbing structure. Specifically, plants are placed in the first and second pots, and rainwater is collected inside the first and second boxes. When the soil around the plant roots is dry, the plant will absorb a large amount of water from the release end, resulting in water loss at the release end. Subsequently, the rainwater will be siphoned from bottom to top to the release end. The entire process is carried out automatically by the water-absorbing structure, which can save water resources and prevent a large amount of water from entering the soil and causing root rot.

[0037] Unlike existing technologies that continuously supply water, the water in this application is mainly supplied based on the demand at the release end, achieving on-demand supply, avoiding water waste, and ensuring that plants can obtain suitable water under different weather conditions, thereby improving the growth quality and survival rate of plants.

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0044] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0045] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0046] See appendix Figures 1-4 As shown, a rotationally molded rainwater siphon-type greening cultivation box includes a first box body 1, a first pot body 2, a second box body 3, and a second pot body 4. The height of the second box body 3 is less than the height of the first box body 1, and it is located on the top side of the first box body 1. The adjacent side walls of the second box body 3 and the first box body 1 are connected. The first pot body 2 is correspondingly located in the box opening facing upwards in the first box body 1, and the second pot body 4 is correspondingly located in the box opening facing upwards in the second box body 3. The bottom of both the first box body 1 and the second box body 3 serve as storage containers. The rainwater storage section 5; when the bottoms of the first box 1 and the second box 3 are both filled with rainwater, the bottom of the first basin 2 and the bottom of the second basin 4 are both higher than or equal to the water surface of the rainwater; it also includes a water absorption structure, which has an intake end 6 and a release end 7. The intake end 6 is located at the bottom of the first box 1 and the second box 3 and is submerged in rainwater. The release end 7 is located inside the first basin 2 and the second basin 4. The water absorption structure is configured to siphon rainwater from bottom to top to the release end 7 through the intake end 6.

[0047] In this embodiment, the fact that the adjacent side walls of the two boxes are connected means that the rainwater collected by the first box 1 and the second box 3 can be shared.

[0048] In this embodiment, the bottom of the first box 1 and the bottom of the second box 3 both include the bottom and the bottom periphery, which means that rainwater will not only accumulate at the bottom but also at the bottom periphery, for example, at the connection between the adjacent side walls of the two boxes.

[0049] In this embodiment, the bottom of the first pot 2 and the bottom of the second pot 4 are both higher than or equal to the water level of the rainwater, which means that the roots of the green plants in the first pot 2 and the second pot 4 will not be soaked by rainwater, reducing the risk of root rot.

[0050] It should be noted that the bottom of the first basin 2 and the bottom of the second basin 4 may or may not be flush; preferably, they are flush.

[0051] Meanwhile, the water level of rainwater is generally below the bottom of the first basin 2 and the second basin 4. In special circumstances, such as heavy rain, the water level may exceed the bottom of the first basin 2 and the second basin 4. In this case, overflow outlets can be set around the first box 1 and the second box 3. When the rainwater exceeds the bottom of the first basin 2 and the second basin 4, the excess water can be overflowed through the overflow outlets.

[0052] In this embodiment, the water-absorbing structure can be made of porous fiber material (such as cotton rope, non-woven fabric, etc.), which is filled with micron-level pores (equivalent to countless capillaries).

[0053] In this embodiment, the automatic supply and discharge of water can be achieved through the water-absorbing structure, which can save water resources and prevent plant root rot. Specifically, the first pot 2 and the second pot 4 are used to place plants, and the first box 1 and the second box 3 collect rainwater. When the soil around the plant roots is short of water, it will absorb a large amount of water from the release end 7, which will cause the release end 7 to lose water. Then, the rainwater will be siphoned from bottom to top to the release end 7. The whole process is carried out automatically by the water-absorbing structure, which can save water resources and prevent a large amount of water from entering the soil and causing plant root rot.

[0054] Unlike the continuous water supply in existing technologies, the water in this application is mainly supplied according to the demand of the release end 7, realizing on-demand supply, avoiding water waste, and ensuring that plants can obtain suitable water under different weather conditions, thereby improving the growth quality and survival rate of plants.

[0055] Preferably, the water-absorbing structure is an absorbent swab, which includes a first swab 8. The first swab 8 automatically siphons rainwater from the water storage part 5 to the release end 7 through capillary force. Multiple first swabs 8 are threaded through the bottom of both the first basin 2 and the second basin 4. All first swabs 8 are perpendicular to the surface of the rainwater, and the lower end of each first swab 8 is the suction end 6, and the upper end is the release end 7. The lower end of the first swab 8 threaded through the first basin 2 extends into the bottom of the first box 1. The lower end of the first swab 8 threaded through the second basin 4 extends into the bottom of the second box 3.

[0056] The length of the first cotton strip 8 threaded through the second basin 4 is less than the length of the first cotton strip 8 threaded through the first basin 2.

[0057] With the above design, water can be evenly supplied to the second basin 4 through multiple first cotton strips 8 threaded through the second basin 4; water can also be evenly supplied to the first basin 2 through multiple first cotton strips 8 threaded through the first basin 2.

[0058] This ensures that the water content is evenly distributed throughout the first basin 2 and the second basin 4.

[0059] Preferably, the absorbent swab further includes a second swab 9; when the bottoms of both the first box 1 and the second box 3 contain rainwater, one end of the second swab 9 is located in the rainwater at the bottom of the first box 1, and the other end passes through the connection between the first box 1 and the second box 3 and extends into the interior along the periphery of the second basin 4; the second swab 9 is used to siphon the rainwater in the first box 1 to the interior area of ​​the second basin 4 by capillary force.

[0060] Since less rainwater collects inside the second box 3, the second basin 4 can be supplied with water through the second cotton swab 9 thanks to the above design.

[0061] Preferably, the bottom side wall of the second box 3 is provided with a second communication port 10, and the side wall of the first box 1 is provided with a first communication port 11. The second communication port 10 is connected to the first communication port 11. The lowest point of the second communication port 10 is higher than the inner surface of the bottom of the first box 1.

[0062] With the above design, the rainwater inside the second box 3 can be combined with the rainwater inside the first box 1. When the rainwater is combined, the rainwater accumulated inside the second box 3 is introduced into the first connecting port 11 through the second connecting port 10, thereby accumulating in the first box 1. After the rainwater accumulates to a certain level at the bottom of the first box 1 (i.e., exceeding the lowest point of the second connecting port 10), it will enter the interior of the second box 3.

[0063] Preferably, the first box 1 includes a hollow base 12 and a box cover 13 disposed on the hollow base 12, wherein the length of the box cover 13 is greater than the length of the second box 3.

[0064] This design guides rainwater to collect within the hollow base 12, while simultaneously increasing the load-bearing area at the bottom of the enclosure 13. When the second enclosure 3 is filled with water, it prevents the enclosure 13 from becoming top-heavy and tipping over due to insufficient load-bearing area at the bottom.

[0065] Preferably, the first box 1 and the first basin 2 are integrally formed by rotational molding to form the first component, and the second box 3 and the second basin 4 are integrally formed by rotational molding to form the second component; the first component and the second component are interconnected and the first box 1 and the second box 3 are connected at a predetermined position; both the first basin 2 and the second basin 4 are provided with a plurality of reserved holes 14 to guide the release end 7 of the water absorption structure into the corresponding basin and position it.

[0066] With the above design, manufacturing efficiency can be significantly improved. Specifically, when the first housing 1 and the first basin 2, and the second housing 3 and the second basin 4 are integrally molded into the first and second components using rotational molding, the separate assembly process can be greatly reduced, eliminating the time consumption and sealing risks associated with welding or splicing multiple parts, effectively lowering overall production costs. Furthermore, the first and second components can be precisely connected at predetermined positions, ensuring seamless alignment of the interfaces between the two housings; simultaneously, multiple pre-drilled holes 14 on the two basins precisely position the water absorption structure release end 7, preventing assembly misalignment and ensuring reliable deployment of key functional components such as the absorbent core and water guide pipe.

[0067] Working principle:

[0068] It is divided into two situations: water storage and water use.

[0069] Specifically, when rainwater collects, the rainwater accumulated inside the second box 3 is introduced into the first connecting port 11 through the second connecting port 10, thereby accumulating inside the first box 1. After the rainwater accumulates to a certain level at the bottom of the first box 1 (i.e., exceeding the lowest point of the second connecting port 10), it will enter the interior of the second box 3.

[0070] In use, plants are placed in the first pot 2 and the second pot 4. Rainwater is collected inside the first box 1 and the second box 3. When the soil around the plant roots is dry, it will absorb a large amount of water from the release end 7, which will cause the release end 7 to lose water. Then, the rainwater will be siphoned from bottom to top to the release end 7. The whole process is carried out automatically by the water absorption structure, which can save water resources and prevent a large amount of water from entering the soil and causing the plant roots to rot.

[0071] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
