Description

Technical Field

[0001] The invention relates to the field of flower pots, in particular to a flower pot with bottom air circulation and watering. Background Art

[0002] A watering pot is a self-irrigating planting container with a built-in water storage structure. The outer pot stores irrigation water, while the inner pot holds soil and plant roots. The two are connected by a capillary medium, which uses capillary action to continuously transport water from the water storage area to the soil layer. When growing orchids, many valuable orchid species have fleshy aerial roots that rely on the "pericarp" tissue on the root epidermis to absorb water and oxygen directly from the air. To ensure the respiration of the plant roots, the bottom of the inner pot is often equipped with air vents or ventilation grilles, allowing air to enter the soil through the bottom gaps and prevent root hypoxia caused by water accumulation. When the outer pot contains a large amount of water, the air at the bottom of the inner pot is squeezed out. As the water volume increases, the contact area between the capillary medium and the water increases, continuously transporting water to the soil, causing the aerial roots to rot due to lack of oxygen. When the water volume is insufficient, the fixed-sized air vents provide continuous strong ventilation, which accelerates water evaporation from the roots, reduces the contact area between the capillary medium and the water, and reduces the efficiency of water transport to the soil, causing the aerial roots to dry out.

[0003] After searching, the publication number CN116649113 discloses a bottom air circulation watering flowerpot; it includes a flowerpot body, the upper part of the flowerpot body has an opening, the bottom of the flowerpot body is provided with a ventilation structure and a support structure, the ventilation structure is connected to the inside of the support structure, the ventilation structure includes a front extension pipe, a rear extension pipe and a wind shield, the support structure includes an outer support surface and support feet, and the support feet are provided with air holes.

[0004] Although existing watering pots solve basic irrigation and oxygen supply needs through a static combination of water storage layers and air vents, the air vents of existing watering pots are fixed in size and cannot dynamically adjust the air circulation efficiency according to changes in water storage, resulting in difficulty in balancing soil moisture and root oxygen supply: when there is sufficient water, the air vents cannot accelerate air circulation, which can easily cause root hypoxia and rot; when there is insufficient water, excessive air circulation will aggravate water evaporation, causing plant dehydration. Summary of the Invention

[0005] In order to solve the problem that the air vents in the watering pots mentioned above are fixed in size and the air circulation efficiency cannot be dynamically adjusted according to the changes in water storage, resulting in difficulty in balancing soil moisture and root oxygen supply: when there is sufficient water, the air vents cannot accelerate air circulation, which can easily cause root hypoxia and rot; when there is insufficient water, excessive air circulation will aggravate water evaporation and cause plant dehydration, the present invention is achieved through the following technical solutions.

When the floating plate rises and falls with the water level, the connecting plate drives the connecting head to move along the second slide, driving the second air permeable plate to rotate to adjust the opening degree of the air permeable holes.

[0007] Preferably, it also includes: a water-absorbing rope, which passes through the bottom plate, the first air-permeable plate and the second air-permeable plate at the same time, with one end of the water-absorbing rope extending into the soil of the inner pot and the other end placed in the water of the outer pot.

[0008] Preferably, the water-absorbing rope includes: an inner tube, which is sleeved on the water-absorbing rope; an outer tube, which is sleeved on the inner tube, and both the inner tube and the outer tube have through holes. The outer tube is configured to rotate on the inner tube to adjust the overlapping range of the through holes on the outer tube and the inner tube.

[0009] Preferably, fixing holes are coaxially provided on the bottom plate, the first air-permeable plate and the second air-permeable plate, and the water-absorbing rope is provided through the fixing holes.

[0010] Preferably, the floating plate includes: a connecting hole, which is opened on the floating plate, and the outer tube passes through the connecting hole; a control rod, which is installed on the inner wall of the connecting hole, and a first sliding groove is opened on the outer wall of the outer tube, and the first sliding groove is spiral-shaped. One end of the control rod is connected to the first sliding groove. When the floating plate is raised or lowered, the control rod slides along the first sliding groove and drives the outer tube to rotate.

[0011] Preferably, the spiral direction of the first chute is opposite to that of the second chute, so that when the floating plate rises, the opening of the through hole of the inner tube decreases and the opening of the air hole of the first air permeable plate increases.

[0033] The present invention is further described below with reference to specific examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of protection of the present invention.

[0034] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0035] Example 1: Reference Figure 1-Figure 5 A bottom-air-circulating watering flowerpot includes an outer basin 100, an inner basin 200, a first air permeable plate 202, a second air permeable plate 203, a floating plate 400, and a connecting plate 401. The floating plate 400 rises and falls with the water level in the outer basin 100, driving the second air permeable plate 203 to rotate via a spiral second chute 402, thereby adjusting the opening of the air holes 204 in the first air permeable plate 202 in real time. When there is sufficient water, the air holes 204 open wider, accelerating air circulation to expel moisture and introduce oxygen, thereby preventing root rot due to lack of oxygen. When there is insufficient water, the air holes 204 open narrower, reducing air circulation and slowing soil evaporation to prevent plant dehydration. This solves the problem of existing fixed air holes 204 being unable to dynamically balance soil moisture and root oxygen supply based on water storage.

[0036] In view of the characteristics of orchid plants' dependence on aerial roots for respiration and succulent plants' fleshy roots having poor waterlogging tolerance, the system can achieve precise regulation of air and water in the root microenvironment, improve the survival rate of precious plants, reduce root damage (such as root rot and dryness) caused by improper ventilation, and reduce maintenance difficulty and economic losses.

[0037] The outer basin 100 and the inner basin 200 are nested in the outer basin 100. The outer basin 100 is provided with ventilation holes 101, which can allow air to circulate in the outer basin 100.

[0038] A through hole 303 is provided at the bottom of the inner basin 200, and a bottom plate 201 and a first air permeable plate 202 are installed in the through hole 303. The bottom plate 201 is located above the first air permeable plate 202, and an air circulation hole is provided on the bottom plate 201. The air circulation hole on the bottom plate 201 is smaller than the air permeable hole 204 on the first air permeable plate 202. The bottom plate 201 can be ventilated while preventing the soil in the inner basin 200 from leaking out of the air permeable hole 204. A rotatable second air permeable plate 203 is also provided at the bottom of the first air permeable plate 202 for adjusting the opening range of the air permeable hole 204 on the first air permeable plate 202. The second air permeable plate 203 is used to adjust the opening range of the air permeable hole 204 on the first air permeable plate 202. 03 and the first air permeable plate 202 are provided with air holes 204 of the same size and number. By rotating the second air permeable plate 203, the air holes 204 on the second air permeable plate 203 and the first air permeable plate 202 are staggered, and the size of the air holes 204 on the first air permeable plate 202 can be adjusted. That is to say, when the air holes 204 on the first air permeable plate 202 and the second air permeable plate 203 overlap, the opening size of the air holes 204 is the largest. When the second air permeable plate 203 is rotated, the second air permeable plate 203 will cover the air holes 204 on the first air permeable plate 202, and the size of the air holes 204 will also be reduced.

[0039] The floating plate 400 moves upward in a straight line under the action of buoyancy, and the connecting plate 401 moves upward vertically synchronously. The initial position of the connecting head 403 is located at the lower end of the second slide groove 402. When the connecting plate 401 moves upward, the side wall of the second slide groove 402 exerts a lateral thrust on the connecting head 403 (the direction is consistent with the tangent of the second slide groove 402), and the connecting head 403 is forced to move toward the upper end of the second slide groove 402 along the second slide groove 402, while pushing the second air plate 203 to rotate clockwise around the axis. The rotation causes the second air plate 203 to gradually align with the air hole 204 of the first air plate 202, and the opening increases.

[0040] The floating plate 400 descends: the floating plate 400 sinks due to gravity, the connecting plate 401 moves vertically downward, the side wall of the second chute 402 presses the connecting head 403 in the opposite direction, the second air permeable plate 203 rotates counterclockwise, the air holes 204 gradually shift, and the opening is reduced.

[0041] The core function of the second slide 402: conversion from linear to rotation: the inclined track of the second slide 402 decomposes the vertical motion into horizontal components, forcing the connector 403 to move along the tangential direction and drive the rotation.

[0042] Reference Figure 10 and Figure 11The rotation of the second air-permeable plate 203 is driven by the floating plate 400 and the connecting plate 401. Specifically, a floating plate 400 is provided in the outer basin 100. The floating plate 400 is arranged in the outer basin 100 and floats on the water surface. The top edge of the floating plate 400 is connected with a vertically extending connecting plate 401. The connecting plate 401 is slidably connected to the outer wall of the inner basin 200. A slide rail is connected to the outer wall of the inner basin 200. The connecting plate 401 is connected to the inner basin 200 through the slide rail. The edge of the second air-permeable plate 203 is connected to the connecting plate 401. When the outer basin 100 As the water level in the tank increases, the floating plate 400 also moves upward, and the floating plate 400 drives the connecting plate 401 to move upward. A second chute 402 is provided on the connecting plate 401 near the second air-permeable plate 203. A connector 403 is connected to the second air-permeable plate 203. The connector 403 is connected to the second chute 402. The second chute 402 is spiral. When the floating plate 400 rises and falls with the water level, the connecting plate 401 drives the connector 403 to move along the second chute 402, driving the second air-permeable plate 203 to rotate to adjust the air-permeable plate 203. The opening and closing degree of the air holes 204 is adjusted. In this way, when the second air plate 203 rises straight up, the connecting head 403 always moves in the second slide groove 402, which will automatically adjust the direction of the second air plate 203. That is to say, the upward movement of the connecting plate 401 drives the second air plate 203 to rotate, that is, when the connecting plate 401 moves upward, the second air plate 203 rotates and gradually opens the air holes 204. The more water there is in the outer basin 100, the greater the opening and closing degree of the air holes 204, and the air volume of the soil at the bottom of the inner basin 200 is increased. The faster the air circulation speed, the larger the air holes 204 can accelerate air circulation, discharge moisture and introduce oxygen to prevent root rot; on the contrary, the less water in the outer pot 100, the liquid level drops, the floating plate 400 also moves downward, and the connecting plate 401 drives the second air permeable plate 203 to rotate in the opposite direction, and the second air permeable plate 203 gradually closes the air holes 204. When the water level in the outer pot 100 decreases, the soil humidity decreases, and air circulation needs to be reduced to slow evaporation and prevent plant dehydration. Reducing the air holes 204 can reduce the soil drying speed caused by excessive oxygen input.

[0043] Reference Figure 5 and Figure 9 A water-absorbing rope 300 is also provided at the bottom of the inner basin 200. The water-absorbing rope 300 passes through the bottom plate 201, the first air-permeable plate 202 and the second air-permeable plate 203 at the same time. The bottom plate 201, the first air-permeable plate 202 and the second air-permeable plate 203 are coaxially provided with fixing holes. The water-absorbing rope 300 passes through the fixing holes. One end of the water-absorbing rope 300 is deeply immersed in the soil of the inner basin 200, and the other end is placed in the water body of the outer basin 100. The water-absorbing rope 300 absorbs the water in the outer basin 100 and supplies water to the soil of the inner basin 200. The more water in the outer basin 100, the greater the contact area between the water-absorbing rope 300 and the water, and the faster the water delivery speed. Therefore, when the water in the outer basin 100 increases, the opening and closing size of the air hole 204 needs to be increased.

[0044] Example 2: The difference between this example and example 1 is that, Figure 6-Figure 8 , an inner tube 301 and an outer tube 302 are sleeved on the water-absorbing rope 300, the inner tube 301 is sleeved on the water-absorbing rope 300, and the outer tube 302 is sleeved on the outside of the inner tube 301, and both the inner tube 301 and the outer tube 302 are provided with through holes 303, and the water in the outer basin 100 enters through the through holes 303 and contacts the water-absorbing rope 300, and the outer tube 302 is arranged to rotate on the inner tube 301 to adjust the overlapping range of the outer tube 302 and the through holes 303 on the inner tube 301. By rotating the outer tube 302, the outer tube 302 and the through holes 303 on the inner tube 301 are staggered, and the opening range of the through holes 303 on the inner tube 301 can be adjusted. That is, the outer tube 302 and the inner tube 301 are interlaced. When the through hole 303 of the outer tube 302 coincides with the through hole 303, the opening size of the through hole 303 is the largest. When the outer tube 302 rotates, the outer tube 302 covers the through hole 303 on the inner tube 301, and the size of the through hole 303 also decreases. The purpose of this design is that when the water in the outer basin 100 increases, the outer tube 302 rotates on the inner tube 301 and reduces the opening range of the through hole 303. When the water volume decreases, the outer tube 302 rotates on the inner tube 301 and increases the opening range of the through hole 303. The length of water in contact with the water absorption rope 300 is P. When the water volume increases, P increases, and the width Q of the through hole 303 will decrease accordingly. When the water volume decreases, P decreases, and the width Q of the through hole 303 will increase accordingly.

[0045] The rotation of the outer tube 302 on the inner tube 301 is also controlled by the lifting and lowering of the floating plate 400. A connecting hole is provided on the floating plate 400, and the outer tube 302 passes through the connecting hole. A control rod 305 is installed on the inner wall of the connecting hole. A first sliding groove 304 is provided on the outer wall of the outer tube 302. The first sliding groove 304 is spiral-shaped, and one end of the control rod 305 is connected to the first sliding groove 304. When the floating plate 400 is lifted or lowered, the control rod 305 slides along the first sliding groove 304 and drives the outer tube 302 to rotate. When the floating plate 400 moves vertically upward, it drives the control rod 305 to move linearly upward, and the control rod 305 drives the outer tube 302 to rotate.

[0046] The vertical relay of the floating plate 400 is decomposed into a normal force (perpendicular to the first sliding groove 304) and a tangential force (along the first sliding groove 304) through the first sliding groove 304. The tangential force generates a rotational torque, and the floating plate 400 drives the control rod 305 to move vertically upward. The end of the control rod 305 slides along the first sliding groove 304. The side wall of the first sliding groove 304 exerts a tangential force on the control rod 305, forcing the outer tube 302 to rotate counterclockwise around the inner tube 301. The through hole 303 of the outer tube 302 is misaligned with the through hole 303 of the inner tube 301, and the exposed width of the through hole 303 is reduced, thereby limiting the length of the water-absorbing rope 300 in contact with the water body.

[0047] The floating plate 400 descends (water level decreases): the control rod 305 moves downward → the side wall of the first slide groove 304 applies reverse force → the outer tube 302 rotates clockwise, the outer tube 302 and the through hole 303 of the inner tube 301 gradually overlap, the width of the through hole 303 increases, and the contact length of the water-absorbing rope 300 increases.

[0048] Spiral direction design

[0049] Reverse spiral coordination: If the spiral direction of the first chute 304 is opposite to that of the second chute 402 of the second air permeable plate 203 (for example, the second chute 402 rotates clockwise and the first chute 304 rotates counterclockwise), when the floating plate 400 rises: the second air permeable plate 203 rotates clockwise (opening ↑) → the air permeability increases; the outer tube 302 rotates counterclockwise (through hole 303 ↓) → the water absorption rate decreases.

[0050] Functional synergy: When there is a lot of water, it accelerates air permeability and inhibits water absorption to prevent the soil from being over-wet; when there is little water, it inhibits air permeability and enhances water absorption to avoid dehydration.

[0051] 1. Operation process when water volume is sufficient (high water level)

[0052] The floating plate 400 rises as follows: the amount of water in the outer basin 100 increases → the water level rises → the floating plate 400 moves vertically upward due to the buoyancy.

[0053] Adjustment of the opening of the air hole 204: the floating plate 400 drives the connecting plate 401 to move upward synchronously → the second sliding groove 402 on the connecting plate 401 squeezes the connecting head 403 of the second air permeable plate 203.

[0054] The connector 403 moves tangentially along the second sliding groove 402 → the second air-permeable plate 203 rotates clockwise around the axis.

[0055] The air holes 204 of the second air permeable plate 203 and the first air permeable plate 202 are gradually aligned → the opening of the air holes 204 increases, and the air circulation is accelerated.

[0056] Function: drain moisture from the soil, introduce oxygen, and prevent root rot due to lack of oxygen.

[0057] Water absorption rate adjustment: When the floating plate 400 moves upward, the control rod 305 slides along the first sliding groove 304 of the outer tube 302.

[0058] The lateral thrust of the control rod 305 drives the outer tube 302 to rotate counterclockwise → the outer tube 302 and the through hole 303 of the inner tube 301 are misaligned → the exposed width of the through hole 303 is reduced.

[0059] Function: To limit the contact area between the water-absorbing rope 300 and water, reduce the water transfer rate, and prevent the soil from being over-wet.

[0060] Synergistic effect: accelerates air permeability + inhibits water absorption: when there is sufficient water, it prioritizes dehumidification and oxygen supply, inhibits excessive water supply, and adapts to the respiratory needs of orchid aerial roots.

[0061] Operation process when the water volume is moderate (stable water level)

[0062] The floating plate 400 is suspended and balanced: the water level of the outer basin 100 is maintained at an intermediate value → the floating plate 400 is stationary at the corresponding height.

[0063] The air holes 204 and the water absorption holes are kept half open: the second air permeable plate 203 is at an intermediate angle → the air holes 204 are opened by about 50%.

[0064] The through holes 303 of the outer tube 302 and the inner tube 301 partially overlap → the contact area between the water-absorbing rope 300 and water is moderate.

[0065] Function: Maintain the dynamic balance of soil moisture and oxygen content to meet the moderate drying needs of the fleshy roots of succulents.

[0066] Operation process when water is insufficient (low water level)

[0067] The floating plate 400 descends when: the amount of water in the outer basin 100 decreases → the water level drops → the floating plate 400 sinks due to gravity.

[0068] Adjustment of the opening of the air hole 204: the connecting plate 401 moves downward → the second slide groove 402 pushes the connecting head 403 in the opposite direction → the second air permeable plate 203 rotates counterclockwise.

[0069] The vent holes 204 are gradually dislocated and the opening is reduced to 20%-30%.

[0070] Function: Reduce air circulation, inhibit soil moisture evaporation and prevent dehydration.

[0071] Water absorption rate adjustment: the floating plate 400 drives the control rod 305 to move downward → the outer tube 302 rotates clockwise → the outer tube 302 and the through hole 303 of the inner tube 301 gradually overlap.

[0072] The exposed width of the through hole 303 increases → the contact area between the water-absorbing rope 300 and water increases.

[0073] Function: Increase water delivery rate, extend water supply cycle, and adapt to plant water requirements during drought periods.

[0074] Synergistic effect: inhibit air permeability + enhance water absorption: when water is insufficient, prioritize water conservation to prevent the roots of succulents from drying out.

[0075] In summary, compared with the existing technology, it has the following beneficial effects:

[0076] The floating plate 400 rises and falls with the water level in the outer basin 100, driving the second ventilation plate 203 via the spiral second chute 402 to adjust the opening of the air holes 204 in the first ventilation plate 202 in real time. When the water level is sufficient, the air holes 204 are opened wider, accelerating air circulation to remove moisture and introduce oxygen, preventing root rot due to lack of oxygen. When the water level is insufficient, the air holes 204 are opened narrower, reducing air circulation and slowing evaporation, thus preventing plant dehydration.

[0077] The suction rope 300 comprises an inner tube 301 and an outer tube 302. The overlap between the through-holes 303 of the inner tube 301 and the outer tube 302 can be adjusted by raising and lowering the float 400, which drives the outer tube 302 to rotate. When the float 400 rises, the first chute 304 rotates the outer tube 302, reducing the opening of the through-hole 303 and limiting the length of contact between the suction rope 300 and the water, thus preventing overwetting of the soil when the water level is high. When the float 400 descends, the through-hole 303 opens wider, enhancing water absorption efficiency. This, in conjunction with the ventilation adjustment, creates a dynamic balance: high water flow results in high ventilation and low water absorption, while low water flow results in low ventilation and high water absorption.

[0078] By utilizing buoyancy drive and mechanical transmission of two spiral chutes, the vertical movement of the floating plate 400 is converted into rotation of the breathable plate and adjustment of the through hole 303 of the water-absorbing rope 300. No additional power device is required, the structure is compact and the transmission is stable, reducing costs and failure rates.
