Description

Technical Field

[0001] The utility model belongs to the technical field of plant cultivation, and particularly relates to a hydroponic device. Background Art

[0002] The existing hydroponic device usually includes a bottle body for containing a culture solution, the upper edge of the planting basket is placed on the bottle mouth of the bottle body, the basket body of the planting basket is placed in the bottle cavity, and the roots of the hydroponic plants extend from the bottom of the planting basket into the culture solution. If the plant roots are always immersed in the culture solution, the plant roots will be insufficiently supplied with oxygen, and the roots will not be able to breathe, resulting in root rot and the death of the plant. In order to avoid the occurrence of the above situation, Chinese patent CN210987524U discloses a hydroponic device, including a hydroponic tank for planting plants; a liquid storage structure for passing nutrient solution into the hydroponic tank so that the roots of the plant are in contact with the nutrient solution; and a liquid discharge structure for discharging the nutrient solution in the hydroponic tank so that the roots of the plant are in contact with the air. The device needs to add a water supply pump, a drainage pump, and a liquid storage container on the basis of the existing hydroponic device, and also needs to set a control module or the user to manually control the pump body. The structure is complex and the cost is high, and it is difficult to promote and apply.

[0003] In addition, the basket frame of the planting basket needs to be adapted to the size of the bottle mouth. If the bottle body is replaced, the plant usually needs to be transplanted into the planting basket used with the bottle body. The transplantation operation usually damages the plant root system, thereby affecting the transplant survival rate of the plant. Chinese patent CN204518761U discloses a hydroponic planting device, including a hydroponic bottle, a planting fence and a planting base plate. A water inlet is provided on the bottle wall at the upper part of the hydroponic bottle. The circular edge at the upper part of the planting fence is mounted on the open top of the hydroponic bottle. The planting base plate is provided on the circular edge at the lower part of the planting fence. The planting base plate is formed by splicing a plurality of base plates separately. A plurality of sockets are provided on the planting base plate. The connecting line of the spliced ​​edges of the planting base plate passes through the center of the socket. Although this scheme can reduce damage to the root system of the plant by separating the planting base plate, it is still necessary to transplant the plant to replace the hydroponic bottle, which still affects the survival rate of the plant. Utility Model Content

[0004] The utility model aims to provide a hydroponic device, which can not only promote the healthy growth of plants, but also facilitate users to replace the culture liquid container.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a hydroponic device, including a planting container for planting plants and a hydroponic base for containing a cultivation liquid, the bottom of the planting container is provided with a bottom hole, the top of the hydroponic base is provided with a cultivation hole, and the upper part is provided with a liquid injection hole; the planting container is placed on the top of the hydroponic base, so that the bottom hole and the cavity of the cultivation hole are connected up and down to form a passage for the roots of the plants to pass through.

[0006] Compared with the prior art, the utility model has the following technical effects: the planting container is completely exposed and arranged above the hydroponic base, making it easy to separate and install the planting container from the hydroponic base, which is convenient for users to replace hydroponic bases of different shapes and can reliably maintain the planting state of the planting container above the liquid level of the cultivation liquid, thereby reducing the difficulty of hydroponic planting for users.

[0016] The specific implementation of the utility model is further described in detail below through the description of embodiments in conjunction with the accompanying drawings.

[0017] Embodiment 1

[0018] A hydroponic device includes a planting container 10 for planting plants and a hydroponic base 20 for containing a culture solution. Figure 1 , 2As shown, the planting container 10 is placed on the top of the hydroponic base 20, and the planting container 10 is exposed and arranged above the hydroponic base 20. The bottom of the planting container 10 is provided with a bottom hole 11, and the top of the hydroponic base 20 is provided with a cultivation hole 21. In specific implementation, the stem and part of the root system of the plant are accommodated in the planting container 10, and most of the root systems of the plant pass through the bottom hole 11 of the planting container 10 and the cultivation holes 21 of the hydroponic base 20 in sequence and immerse in the cultivation liquid in the hydroponic base 20. In this way, the plant planted in the planting container 10 can be conveniently transplanted to any hydroponic base 20 with the planting container 10. The operation is simple and convenient and will not damage the root system of the plant. The user can conveniently combine and match the planting containers 10 and the hydroponic base 20 of different appearances to obtain the desired ornamental effect of the hydroponic plant.

[0019] The upper part of the hydroponic base 20 is provided with a liquid injection hole 22. When the user injects the culture liquid from the liquid injection hole 22, it is convenient and intuitive to observe whether the culture liquid overflows, thereby avoiding waste of the culture liquid. The position of the liquid injection hole 22 determines the highest liquid level of the culture liquid in the cavity of the hydroponic base 20. When the liquid injection hole 22 is arranged at the top wall 23 of the hydroponic base 20, the highest liquid level that the culture liquid in the hydroponic base 20 can reach is the upper surface of the top wall of the hydroponic base 20, and the planting container 20 is placed on the top wall 23 of the hydroponic base, which makes the liquid level of the culture liquid arranged near the root outlet of the planting container 10, and the root system of the plant will not be completely immersed in the culture liquid, so that the root system of the plant can always perform a certain breathing action, thereby reducing the difficulty of plant maintenance and extending the life of the plant.

[0020] When the injection hole 22 is arranged on the side wall of the hydroponic base 20, the highest liquid level of the culture liquid is the lower end of the injection hole 22. If the lower end of the bottom hole 11 is not lower than the lower end of the injection hole 22, the air gap between the root outlet of the planting container 10 and the highest liquid level of the culture liquid can be effectively maintained. Figure 1 As shown, the injection hole 22 is arranged at the top wall 23 of the hydroponic base 20, so that the highest liquid level of the culture solution is the upper hole opening of the injection hole 22. In order to make the root outlet of the planting container 10 not lower than the liquid level of the culture solution, the lower hole end of the bottom hole 11 should not be lower than the upper hole end of the injection hole 22.

[0021] In order to facilitate the injection of the cultivation liquid into the cavity of the hydroponic base 20, the injection hole 22 and the cultivation hole 21 in this embodiment are two holes separated from each other, and the opening of the injection hole 22 is completely exposed to the side of the bottom wall of the planting container 10. In other embodiments, the injection hole 22 can also be a recessed portion of the cultivation hole 21, that is, a special-shaped hole is opened on the top wall 23 of the hydroponic base 20, and the hole edge of the special-shaped hole can support the base of the planting container 10, and part of the hole area of ​​the special-shaped hole is blocked below the planting container 10 and is for the root system of the plant to pass through, and part of the hole area is exposed from the side of the planting container 10 so that the user can directly inject nutrient solution, and the cultivation solution can be clean water or nutrient solution.

[0022] Obviously, as long as the injection hole 22 has an exposed hole area for the user to directly inject the culture liquid, the demand can be met. In a further preferred embodiment, the injection hole 21 is arranged adjacent to the side wall of the hydroponic base 20, as shown in the attached Figure 1 As shown, the injection hole 22 in this embodiment is arranged adjacent to the edge of the top wall 23, so that when a larger planting container 10 is placed on the hydroponic base 20, the injection hole 22 still has an exposed hole area. In this embodiment, only one injection hole 22 is provided on the top wall 23, and in other embodiments, multiple injection holes 22 may also be provided on the top wall 23.

[0023] During specific implementation, the planting container 10 is supported on top of the hydroponic base 20 and is always located above the liquid surface of the culture liquid. The shapes and contours of the planting container 10 and the hydroponic base 20 can be fully displayed, so that the planting container 10, the hydroponic base 20 and the planted plants together constitute a hydroponic potted landscape to meet the interests of users.

[0024] In this embodiment, a planting container 10 is placed above the hydroponic base 20. In other embodiments, a plurality of planting holes 21 and injection holes 22 may be opened on the top wall of the hydroponic base 20, and a plurality of planting containers 10 may be configured to form a hydroponic potted plant combination.

[0025] Embodiment 2

[0026] The difference between this embodiment and the first embodiment is that the hole area of ​​the cultivation hole 21 of the hydroponic base 20 is larger than the outer contour of the bottom of the planting container 10. In order to prevent the lower part of the planting container 10 from entering the cavity of the hydroponic base 20 through the cultivation hole 21, a gasket 30 can be added above the cultivation hole 21 to support the planting container 10.

[0027] Details are as attached Figure 3 As shown, the gasket 30 is sandwiched between the planting container 10 and the hydroponic base 20, the outer edge of the gasket 30 is placed above the edge of the cultivation hole 21, and the middle part of the gasket 30 is provided with a hole for the plant roots to pass through, and the hole area of ​​the hole is smaller than the outer contour of the bottom of the planting container 10 to ensure its reliable support for the planting container 10.

[0028] Embodiment 3

[0029] The difference between this embodiment and the first embodiment is that the cultivation hole 21 is a stepped hole that is larger at the top and smaller at the bottom, and its stepped table top 211 is abutted against the bottom of the planting container 10 to support the planting container 10, and the hole wall of the upper large hole section of the stepped hole is abutted against the outer wall of the planting container 10 to limit the displacement of the planting container 10 in the wall direction of the top wall 23 of the hydroponic base.

[0030] As attached Figure 5As shown, in this embodiment, the highest liquid level of the cultivation liquid is the upper end of the injection hole 22, and the stepped table 211 is lower than the upper end of the injection hole 22. Therefore, in the preferred embodiment, the height difference between the stepped table 211 and the top wall 23 of the hydroponic base can be reduced, or a planting container 10 with a bottom angle can be selected to maintain the root air gap.

[0031] In other embodiments, the cultivation hole 21 may also be a tapered hole, and the tapered hole surface thereof abuts against the bottom of the planting container 10 to limit the displacement of the planting container 10 .

[0032] Embodiment 4

[0033] The difference between this embodiment and the first embodiment is that the hydroponic base 20 includes a peripheral edge 24 arranged around the outer peripheral edge of the top wall 23, and the peripheral edge 24 is a closed ring. In this way, when the user injects the culture liquid into the inner cavity of the hydroponic base 20 from the injection hole 22, if the culture liquid overflows, it can also be intercepted by the peripheral edge 24 to prevent the overflowed culture liquid from flowing under the hydroponic base 20. The height of the peripheral edge 24 used to enclose the culture liquid overflowing from the injection hole 22 is preferably less than 2 mm.

[0034] In order to accelerate the flow of the culture liquid into the cavity of the hydroponic base 20, a plurality of injection holes 22 are provided on the top wall 23 at intervals in this embodiment. Figure 6 As shown, five arc-shaped liquid injection holes 22 are evenly arranged at equal angles around the core of the cultivation hole 21.

[0035] Embodiment 5

[0036] The difference between this embodiment and the fourth embodiment is that protrusions 25 are arranged around the cultivation hole 21, and the protrusions 25 are short platforms and short columns arranged at intervals, which are used to support the planting container 10. The protrusion height of the protrusion 25 is not lower than the protrusion height of the surrounding edge 24, that is, the height difference between the top surface of the protrusion 25 and the top surface of the top wall 23 is greater than the height difference between the lowest point of the surrounding edge 24 and the top surface of the top wall 23, so that the planting container 10 can be supported, so that the bottom surface of the planting container 10 is higher than the top surface of the surrounding edge 24, thereby maintaining the height difference between the bottom hole 11 and the highest liquid level of the cultivation solution.

[0037] Embodiment 6

[0038] The difference between this embodiment and the fifth embodiment is that the protrusion 25 is a closed circle body. Figure 8 As shown, the protrusion 25 constitutes the hole wall of the cultivation hole 21. While the protrusion 25 supports the planting container 11, the planting container 10 covers the cultivation hole 21, which can reduce the open area and prevent the growth of green moss inside the hydroponic base 20 from affecting the root system's absorption of nutrients in the cultivation solution.
