Description

Technical Field

[0001] This utility model belongs to the technical field of indoor plant cultivation devices, and more specifically, it relates to an indoor plant cultivation rack. Background Technology

[0002] Indoor plant racks are commonly used in homes or offices to arrange potted plants in tiers to save space. However, existing racks of this type generally suffer from the following drawbacks: 1. Traditional racks have fixed legs, requiring manual lifting and movement to adjust placement or clean the plants. For multi-tiered racks fully loaded with plants, this significantly increases weight, making movement strenuous and potentially damaging to the floor. 2. Existing plant racks typically have flat surfaces, allowing excess water to drip directly from the pot holes onto the lower surface or floor. While some designs include drainage holes, they lack effective drainage mechanisms, causing wastewater to flow freely along the rack, polluting the indoor environment and potentially creating slippery floors. 3. A few improved designs incorporate water containers at the bottom to collect dripping wastewater, but these containers are directly exposed on the outside of the rack. External containers occupy extra floor space, are visually cluttered, and the exposed wastewater detracts from the aesthetics of the room. 4. In common cultivation racks, the base support area is similar to that of the upper shelf. When plants are unevenly distributed or the rack is subjected to external impact, it is prone to tipping over due to a shift in the center of gravity. This is especially true in designs with bottom-mounted casters; if the casters are only located on both sides of the base, stability is further reduced.

[0003] Therefore, improvements are urgently needed to meet the needs of indoor plant cultivation. Utility Model Content

[0033] Figure 1 An implementation of an indoor plant cultivation rack is shown, comprising: a base 2 with rollers 1 mounted at its lower end and a connection interface at its upper end; a support rod 4 with its lower end vertically fixed to the connection interface of the base 2; multiple plant cultivation platforms 8 (two plant cultivation platforms are shown as an example in the figure), each with a vertically extending sliding sleeve 6 at its center, the sliding sleeve 6 being spaced out and fitted onto the support rod 4, so that the multiple plant cultivation platforms 8 are horizontally distributed vertically; each plant cultivation platform 8 is a rigid board with multiple grooves for placing flower pots 14 on its surface, and a drain outlet at the bottom of the groove, the drain outlet being covered by a filter screen 7; a water collection tank 17 located at the bottom of the plant cultivation platform 8, the top opening of which is connected to the drain outlet; one end of the water collection tank 17 is connected to a water guide pipe at its bottom, and the other end of the water guide pipe is connected to a wastewater collection tank 16; the wastewater collection tank 16 is mounted on the base 2.

[0034] This utility model enables free movement through rollers 1; the drain outlet, water collection trough 17 and wastewater collection box 16 form a closed-loop drainage system to prevent sewage overflow and solve the problems of traditional plant racks being inconvenient to move and watering sewage polluting the indoor environment.

[0035] According to one embodiment of this utility model, when the width of the culture platform is 40cm×40cm, the base 2 can be a square steel plate with a width of 50cm×50cm to 60cm×60cm and a thickness of 1-2cm. Polyurethane universal casters 1 with a diameter of 5cm can be installed at the four corners of its lower surface, and the casters 1 have a load-bearing capacity of 50kg. A steel connecting interface with an outer diameter of 4cm and a depth of 3cm can be welded to the center of the upper surface of the base 2. The support rod 4 can be a 304 stainless steel round tube with a length of 150cm and an outer diameter of 4cm, and its lower end can be inserted into the connecting interface of the base 2 and radially locked and fixed by M6 bolts. After assembly, the support rod 4 remains perpendicular to the base 2, with a perpendicularity tolerance controlled within 2°. During use, by pushing the base 2 as a whole to the desired position, the braking device of the casters 1 can lock to prevent displacement. This design achieves stable load-bearing and convenient movement. The plant cultivation platform 8 can be made of 40cm×40cm×1cm ABS plastic board. Six or eight grooves with a diameter of 10-20cm and a depth of 2-3cm can be arrayed on the board. A drain outlet with a diameter of 1-2cm can be made at the center of the bottom of each groove. An 80-mesh nylon filter screen 7 can be placed above the drain outlet (or the filter screen 7 can be a detachable double-layer structure, including an upper 80-mesh nylon mesh and a lower 1mm aperture stainless steel filter plate; the upper 80-mesh nylon mesh is easy to remove and clean). The sliding sleeve 6 can be made of 4.1cm inner diameter PVC round pipe, vertically fixed to the center of the cultivation platform, with a 0.05cm gap between it and the support rod 4. After sliding to the target height, the sliding sleeve 6 is fixed to the support rod 4 with screws. Space is reserved between the sliding sleeve 6 and the support rod 4 for embedding a water guide pipe. The water collection tank 17 can be made of transparent PP plastic with a depth of 5cm. The top can be fitted with a snap-fit ​​structure to connect it to the bottom plate of the cultivation platform. The tank has a volume of 500ml. A water guide pipe is connected to the lowest point of the tank (the water guide pipe consists of a rigid connection section and a flexible drainage section. The rigid connection section is the inclined section from the bottom outlet of the water collection tank 17 to the side of the support rod 4, made of UPVC rigid pipe with an inner diameter of approximately 10mm and a wall thickness of 1.5mm, fixed to the surface of the support rod 4 with snap-fits to prevent bending. The flexible drainage section is the vertical section from the side of the support rod 4 to the wastewater collection tank 16, made of silicone flexible tubing with a Shore hardness of approximately 60A, with a 10% length allowance to accommodate displacement). During operation, water overflowing from the flowerpot 14 flows into the water collection tank 17 after being filtered through the grooved drain outlet, and then drains out through the water guide pipe. The wastewater collection tank 16 can be made of HDPE plastic with a capacity of 5-10L. A 2cm diameter water inlet and vent hole can be opened on the top of the tank; the end of the water pipe can be inserted into the water inlet to form an interference fit. The wastewater collection tank 16 can be placed in the central area of ​​the base 2, and an anti-slip rubber pad can be installed on the bottom of the tank. A limiting edge with a height of 2cm can be welded to the surface of the base 2 to restrain the horizontal displacement of the wastewater collection tank 16.During use, wastewater flows into the wastewater tank through the drain pipe. When the water level reaches half of the total height, the water level is displayed through a transparent observation window on the side wall of the tank, allowing the user to remove the tank and empty the wastewater. This structure achieves closed-loop wastewater collection.

[0036] This invention achieves the free movement of the cultivation rack through the combination of a movable base 2, layered drainage channels, and centralized wastewater collection. At the same time, it facilitates the directional collection of irrigation wastewater to prevent overflow, reducing the workload of cleaning and maintenance.

[0037] According to another embodiment of this utility model, a storage container 3 is also included. The storage container 3 can be a rattan flower basket with a height of 25cm and a diameter of 30cm. A 2mm thick rubber anti-slip mat can be laid on the bottom of the flower basket. A circular hole with a diameter of 4.2cm can be opened in the center of the bottom wall of the flower basket, and the edge of the circular hole can be covered with a PVC reinforcing ring. During assembly, the lower end of the support rod 4 passes through the circular hole of the flower basket, and the bottom surface of the flower basket is placed on the surface of the base 2. The gap between the circular hole and the support rod 4 is controlled within 0.1cm. During operation, the flower basket forms a radial constraint with the support rod 4 through the circular hole to avoid horizontal displacement. The wastewater collection tank 16 can be a rectangular HDPE water tank with a capacity of 5L and a height of 20cm. A water inlet hole with a diameter of 1.5cm can be opened on its top, and a transparent water level observation window can be set on the side wall. During assembly, the wastewater collection tank 16 is placed inside the storage container 3, with the bottom of the tank in contact with the rubber pad on the inner bottom surface of the storage container 3. The end of the water pipe is inserted into the water inlet hole of the tank to a depth of 3cm. The internal space of the storage container 3, with a height of 25cm, and the wastewater tank, with a height of 20cm, form a 5cm margin. During use, wastewater flows into the wastewater tank through the water pipe, and the water level can be identified through the observation window when it reaches 4L. A humidifier 15 can be placed in the space above or next to the wastewater collection tank 16 inside the storage container 3; the humidifier 15 can be an ultrasonic atomizer with a bottom area of ​​15cm × 15cm and a height of 10cm. During assembly, the humidifier 15 is placed on the top cover surface of the wastewater collection tank 16 (avoiding the vent holes and water inlet holes on the top cover), maintaining a 3cm heat dissipation gap between them. The open area at the top of the storage container 3 can store small gardening tools. During operation, the wastewater collection and equipment storage functions are implemented in layers in the vertical space without interfering with each other. This utility model integrates the functions of wastewater tank storage and equipment placement through the storage container 3, avoiding the impact of exposed water tanks on visual neatness, while utilizing vertical space to increase practical storage area.

[0038] According to another embodiment of this utility model, the base 2 can be made of a square steel plate with a side length of 60cm and a thickness of 1cm; or a circular aluminum alloy frame with an outer diameter of 60cm and a frame beam width of 5cm. Other decorations or items can be placed on the flat base as needed, improving space utilization. The upper surface of the base 2 is 10cm above the ground, and its width is 20cm wider than the plant cultivation platform 8. During assembly, the base 2 is placed horizontally on the ground, and the support rod 4 is vertically fixed to the center point of the base 2. During operation, widening the base 2 ensures that the projection of the support rod 4 is always located in the geometric center area of ​​the base 2's boundary.

[0039] Rollers 1 can be 5cm diameter polyurethane casters, each with a load capacity of 30kg; four rollers are used, installed at the four corners of base 2 (for square bases); for round bases 2, rollers 1 are mounted on four evenly distributed lugs. During assembly, rollers 1 are fastened to the lower surface of base 2 with M8 bolts, with the bottom of rollers 1 0.5cm below the plane of base 2. During movement, all four rollers 1 touch the ground simultaneously, with a maximum load capacity of 120kg. Four reinforcing ribs with a cross section of 3cm×3cm can be welded to the lower surface of base 2, intersecting at the interface of support rod 4 in a cross shape. 5mm thick reinforcing pads can be added to the roller 1 mounting positions. During operation, when the culture rack is subjected to lateral thrust, the four rollers 1 form a rectangular support surface, and the reinforcing ribs distribute stress to the edge of base 2. Tilting tests show that the rack only becomes unstable when the tilt angle exceeds 15°. This embodiment improves the anti-tilting ability of the culture rack by optimizing the geometric dimensions and the layout of the four corner rollers 1, ensuring the structural stability in both moving and stationary states.

[0040] According to another embodiment of this utility model, the support rod 4 can be made of 304 stainless steel pipe with an outer diameter of 4cm, and multiple sets of spare screw holes 13 are opened along the axial direction at intervals of 5cm; the screw holes can be made of M6 internal thread with a depth of 10mm; each set contains two radially symmetrical screw holes, and the included angle between adjacent sets is 90°. During assembly, the support rod 4 is vertically fixed to the connection interface of the base 2, and the axis of the screw holes remains horizontal. During operation, the array of spare screw holes 13 covers the effective length range of 120cm of the support rod 4. The sliding sleeve 6 can be made of PVC pipe with an inner diameter of 4.1cm and a wall thickness of 3mm, and its side wall has radially opened threaded through holes; the locking screw 5 can be made of M6×20mm stainless steel wing screw. During assembly, the sliding sleeve 6 is fitted onto the outer surface of the support rod 4, and the center line of the threaded through hole is aligned with the spare screw hole 13; the locking screw 5 is screwed into the threaded through hole until the end is tightened with the spare screw hole 13 corresponding to the support rod 4. During adjustment, the locking screw 5 is tightened so that its end is embedded in the spare screw hole 13 to a depth of 3mm. The plant cultivation platform 8 is connected to the support rod 4 via a sliding sleeve 6, and each cultivation platform is equipped with two locking screws 5. During operation, first loosen the locking screws 5, then slide the cultivation platform up and down along the support rod 4 to the target height; when the through hole of the sliding sleeve 6 aligns with the spare screw hole 13, tighten the locking screws 5 until the torque reaches 1.5 N·m. Tests show that a single locking screw 5 can withstand a vertical load of 20 kg, and the double screw configuration meets the 40 kg load requirement. This embodiment, through a standardized screw hole array and mechanical locking structure, achieves adjustable cultivation platform height to adapt to the growth space needs of plants of different heights.

[0041] According to another embodiment of the present invention, it also includes an irrigation device, such as... Figure 2-3 As shown, the irrigation device includes a humidifier 15 and an irrigation pipe 11.

[0042] The humidifier 15 can be an ultrasonic atomizer with a base size of 15cm × 15cm and a height of 10cm; its atomization capacity is 300ml / h, and its water tank capacity is 2L. During assembly, the humidifier 15 is placed above the wastewater collection tank 16 inside the storage container 3, with a 3cm gap for heat dissipation between them. A non-slip silicone pad can be installed on the bottom of the humidifier 15, with the spray nozzle facing upwards. During operation, the humidifier 15 generates water mist after being powered on, and the mist is output vertically upwards from the spray nozzle. The pouring pipe 11 can be a food-grade silicone hose with an inner diameter of 8mm and a length of 180cm. During assembly, one end of the pouring pipe 11 is connected to the spray nozzle of the humidifier 15 and secured with a clamp; the other end extends upwards along the surface of the support rod 4, and the pipe is fixed to the support rod 4 every 30cm with nylon cable ties. The top of the pouring pipe 11 terminates 10cm above the top of the support rod 4. A 5mm gap is maintained between the pouring pipe 11 and the surface of the support rod 4 during the installation path. The irrigation pipe 11 has two rows of axially distributed misting holes 12 on its wall; the upper row of holes is located 5 cm below the top of the pipe, and the lower row is located in the middle of the pipe. Each row has 12 holes, each 5 mm in diameter, with a spacing of 2 cm between them. During operation, when the humidifier 15 is activated, water mist enters the irrigation pipe 11 through the spray nozzle and diffuses outwards through the misting holes 12. This not only irrigates indoor plants but also creates a beautiful misty effect. Tests show that water mist can adhere to plant leaves within a 20 cm radius of the irrigation pipe. This embodiment, through the tiered misting hole design 12, allows water mist to cover plant cultivation areas at different heights, reducing the frequency of manual watering.

[0043] According to another embodiment of this utility model, the water collection tank 17 can be a PP plastic tank of 45cm×45cm×6cm, and the top of the tank wall can be provided with an outward flange with a width of 3cm; the flange thickness is 2mm, and the height of the upper surface from the bottom of the tank is 6cm. During assembly, the water collection tank 17 is fixed to the bottom of the support rod 4 by four L-shaped buckles, and the flange plane remains horizontal. During operation, the outer edge of the flange extends 2.5cm beyond the boundary of the plant cultivation platform 8. The sliding sleeve 6 can be an ABS plastic sleeve with a height of 8cm and an inner diameter of 4.1cm; its lower end can be interference-fitted with the center hole of the water collection tank 17, with a fit depth of 3cm. The plant cultivation platform 8 can be an ABS board of 40cm×40cm×1cm, and the edge of the board can be provided with a downward-bent flange with a flange height of 1cm. During assembly, the cultivation platform is placed on the upper surface of the flange of the water collection tank 17, and the gap between the four sides of the board and the inner side of the flange is 0.5cm. After installation, the top of the sliding sleeve 6 is 2cm lower than the surface of the cultivation platform. The height difference between the upper surface of the flange and the upper plane of the cultivation platform is 1.5 cm. When water overflows from the flowerpot 14 and flows onto the surface of the cultivation platform, the water flow is blocked by the flange and guided into the water collection tank 17. In the test, when the amount of water poured in a single session exceeded 200 ml, the overflow water was still confined within the area surrounded by the flange. During disassembly and cleaning, the water collection tank 17 can be separated simply by lifting the cultivation platform. This embodiment effectively prevents irrigation wastewater from seeping out from the edge of the cultivation platform through the flange enclosure structure, reducing the risk of pollution to the surrounding environment.

[0044] According to another embodiment of this utility model, the bottom inclination angle of the water collection tank can be set to a taper of 1° to 5°, preferably 2° to 3° to meet the gravity drainage requirements. The overall size of the water collection tank can be a square with a side length of 40cm to 50cm or a circle with the same diameter, and the depth can be designed to be 5cm to 8cm. The inner diameter of the water guide pipe can be adapted to a specification of 8mm to 15mm, and the pipe length is adjusted according to the actual floor height spacing. The material of the water collection tank can be polypropylene plastic, and the wall thickness can be controlled to 1.5mm to 2.5mm to balance strength and weight. The material of the soft drainage section of the water guide pipe can be food-grade silicone, with a Shore hardness of 50A to 60A and a temperature resistance range of -30℃ to 120℃. The water collection tank can be an injection-molded conical-bottom container, and its bottom slope is achieved by molding. One end of the water guide pipe is sealed to the water outlet at the bottom of the water collection tank through a clamp connector. During assembly, the vertical axis of the water collection tank must coincide with the support rod, with the lowest point of its sloping bottom directly below the center. The water guide pipe extends axially along the support rod, passing through the gaps in the inner walls of each sliding sleeve before connecting downwards to the wastewater collection tank. The inlet height of the wastewater collection tank must be lower than the lowest point of the lowest water collection tank, utilizing the elevation difference to create gravity-fed drainage. Excess water after watering flows into the water collection tank through the drain outlet of the plant cultivation platform's recess. Due to the sloping shape of the water collection tank's bottom, which is lower in the center and higher at the edges, wastewater automatically converges towards the lowest point under gravity. The water guide pipe inlet is located at this lowest point, ensuring that wastewater flows seamlessly into the wastewater collection tank without stagnation. This design eliminates horizontal stagnation areas inside the water collection tank, improving drainage efficiency. The sloping bottom combined with directional flow avoids localized water accumulation, reducing the risk of algae and bacterial growth and lowering the frequency of cleaning and maintenance.

[0045] This implementation uses a bottom-sloping design to connect to the low-level water pipe, ensuring that wastewater is completely discharged from the collection tank by gravity, eliminating hygiene hazards caused by residual water. This structure requires no external power, is simple to maintain, and is highly reliable.

[0046] According to another embodiment of this utility model, the storage container 3 is a cylindrical structure with an open top and a through hole in its bottom wall; the support rod 4 passes through the through hole of the storage container 3 and is fixedly connected to the base 2; a wastewater collection tank 16 is placed at the bottom of the storage container 3, and a humidifier 15 is placed at the top; the irrigation pipe 11 extends from the spray nozzle of the humidifier 15, passes through the open top of the storage container 3, the gap between the inner wall of the sliding sleeve 6 of the water collection tank 17 and the support rod 4, and extends to the top of the support rod 4; the water guide pipe extends from the outer wall of the humidifier 15 to the wastewater collection tank 16. The first water guide pipe 9 is connected to the upper water collection tank 17, and passes through the open top of the storage container 3, the gap between the inner wall of the sliding sleeve 6 of the lower water collection tank 17 and the support rod 4, and extends to the bottom of the upper water collection tank 17. The second water guide pipe 10 is connected to the lower water collection tank 17, and passes through the open top of the storage container 3, extends along the axial direction of the support rod 4, and connects to the bottom of the lower water collection tank 17.

[0047] The storage container 3 is a woven rattan flower basket (30cm in diameter, 25cm in height), with a 5.5cm diameter circular hole in the center of the bottom wall. The support rod 4 (4cm in outer diameter or side length) passes through this hole. The irrigation pipe 11 is a silicone flexible tube (1cm in outer diameter, Shore hardness can be selected to be around 60A) leading out from the humidifier 15, passing through the opening on the top of the flower basket, and entering the 1.0-1.5cm gap between the support rod 4 and the sliding sleeve 6 (5.0cm in inner diameter), and going up to the top along the gap. The lower layer of the flower basket holds a wastewater tank (5L capacity), and the upper platform holds the humidifier 15 (15×15cm), without interference between them. The through-hole design of this utility model allows the storage container 3 and the support rod 4 to form a positioning fit, avoiding movement and displacement; the irrigation pipe 11 uses the gap of the sliding sleeve 6 for wiring, avoiding pipe compression when adjusting the plant cultivation platform 8; the storage container 3 integrates the wastewater tank storage and the humidifier 15's carrying function and wastewater drainage, reducing the space occupied by independent components and achieving the aesthetic requirements of indoor design.

[0048] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be easily made by those skilled in the art.
