For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] As Figures 1-4 shown, a hydroponic planting horizontal wind and humidity control device according to an embodiment of the first aspect of the present utility model includes a cabin body 100, a hydroponic rack body 200, an atomization module 300, and a plurality of cross-wind modules 400. The cabin body 100 has an inner cavity. The hydroponic rack body 200 is in a long strip shape. A plurality of hydroponic layer racks 210 are arranged in upper and lower layers on the hydroponic rack body 200. A plurality of hydroponic dishes 220 are arranged along the length direction of the hydroponic layer rack 210. There is a first interval space between two adjacent upper and lower hydroponic layer racks 210. The atomization module 300 is arranged in the cabin body 100. The mist output port 310 of the atomization module 300 is communicated with the inner cavity. Each cross-wind module 400 is correspondingly arranged above each hydroponic layer rack 210. The cross-wind module 400 is used to drive the air flow to flow along the length direction of the hydroponic rack body 200.

[0029] Among them, the cabin body 100 can be built by a container or a greenhouse to form a relatively enclosed inner cavity. A storage cavity independent of the inner cavity can also be separated in the cabin body 100. The atomization module 300 can include a conventional water storage container and an atomizer. The atomizer can be a pressure atomizer, an ultrasonic atomizer, etc. The atomization output end of the atomizer faces the inner cavity. The atomizer atomizes the water in the water storage cavity to output it into the inner cavity, thereby increasing the humidity of the inner cavity.

[0030] The hydroponic rack body 200 is in a long strip shape. The hydroponic rack body 200 can be rectangular when viewed from above. The hydroponic rack body 200 can include four vertical racks and a plurality of intermediate frames. The four corners of the intermediate frame are respectively connected to the four vertical racks, and a plurality of intermediate frames are arranged from top to bottom. The hydroponic layer rack 210 is fixed by the intermediate frame. The hydroponic dishes 220 are arranged at intervals on the hydroponic layer rack 210, and the hydroponic dishes 220 are provided with planting grooves. Fruit and vegetable plants can be placed on the planting grooves for planting.

[0031] The crosswind humidity control device for hydroponic cultivation of the present utility model is such that fruit and vegetable plants can be planted on the hydroponic dish 220 and grow in the first spaced space on the hydroponic dish 220. The mist outlet 310 of the atomization module 300 outputs mist into the inner cavity. After the fruit and vegetable plants grow to a certain height, they will cause a certain obstruction to the flow of the air current, and the mist accumulates in some areas. The crosswind module 400 drives the air current to flow along the length direction of the hydroponic rack 200, thereby driving the mist to disperse to each area. This design makes the humidity in the areas where each hydroponic dish 220 on each layer of the hydroponic rack 200 is located approximately uniform by outputting a crosswise air current, optimizing the control of the planting environment conditions and improving the planting effect.

[0032] The crosswind module 400 can be arranged at the end of the long strip-shaped first spaced space between two layers of hydroponic shelves 210, and can drive the air current to blow from one end of the first spaced space to the other end. Or, in some embodiments of the present utility model, such as Figure 1 、 2 shown, the crosswind module 400 includes a plurality of crosswind fans 410, the crosswind fans 410 are arranged along the length direction of the hydroponic rack 200, and each crosswind fan 410 is arranged corresponding to the hydroponic dish 220 one by one, and the crosswind fan 410 is used to drive the air current to flow along the length direction of the hydroponic rack 200.

[0033] The plurality of crosswind fans 410 are arranged along the length direction of the hydroponic rack 200, which can make the intensity of the air current not gradually decrease in the length direction, further make the distribution of the mist more uniform, and reasonably control the humidity in each area.

[0034] In some embodiments of the present utility model, such as Figure 1 、 2 shown, the crosswind fans 410 above each layer of the hydroponic shelf 210 are arranged on the bottom surface of the upper layer of the hydroponic shelf 210, so as to provide a more sufficient growth space for the growth of fruit and vegetable plants. At the same time, since most of the mist will accumulate on the top of the fruit and vegetable plants after they grow, and the crosswind fans 410 are located on the bottom surface of the upper layer of the hydroponic shelf 210, close to the top of the fruit and vegetable plants, they can better drive the air current to flow.

[0035] In some embodiments of the present utility model, such as Figure 4 shown, the hydroponic shelf 210 is provided with a humidity sensor 500 corresponding to each hydroponic dish 220, the humidity sensor 500 is used to detect the humidity signal, and the humidity sensor 500 is electrically connected to the crosswind fan 410 corresponding to the hydroponic dish 220 to drive the crosswind fan 410 to start according to the humidity signal.

[0036] Each humidity sensor 500 can detect the humidity of the area where each hydroponic dish 220 is located in a one-to-one correspondence. When the humidity of a certain area is high, the crosswind fan 410 in that area starts, and the air flow disperses the fog, thereby reducing the humidity here. By using each humidity sensor 500 to detect the humidity of each area and controlling the corresponding crosswind fan 410 to start, the humidity of the area can be adjusted more purposefully.

[0037] Specifically, the hydroponic cultivation crosswind humidity control device further includes a control module 600, which can be selected from an MCU or a CPU and its peripheral circuits. The control module 600 is respectively connected to each humidity sensor 500 and each crosswind fan 410 to control the start and stop of the crosswind fan 410 according to the humidity signal fed back by the humidity sensor 500.

[0038] In some embodiments of the present invention, as Figure 2 、 3 shown, the hydroponic rack 200 has at least two rows. Multiple rows of hydroponic racks 200 are arranged side by side, and there is a second interval space between two adjacent rows of the hydroponic racks 200. The atomizing output port of the atomizing module 300 is located above the second interval space and outputs fog toward the hydroponic racks 200 on both sides.

[0039] The atomizing output port is located obliquely above the hydroponic rack 200. After the fog is output from the atomizing output port, it will deposit downward and then enter the first interval space from the side of the hydroponic rack 200. And the second interval space provides a space for the fog to sink. Hydroponic racks 200 are arranged on both sides of the second interval space, so that the fog output from the atomizing output port can be fully utilized.

[0040] In some embodiments of the present invention, as Figure 1 、 3 shown, the cabin 100 is further provided with a water delivery module and a water return module. The water delivery module extends to each hydroponic dish 220 through a water delivery pipe group. The water delivery pipe group is provided with water outlets corresponding to each hydroponic dish 220. The water return module extends to each hydroponic dish 220 through a water return pipe group. The water return pipe group is provided with water inlets communicated with each hydroponic dish 220. The water delivery module is communicated with the water return module to supply the returned water to each hydroponic dish 220.

[0041] Among them, the water delivery pipe group can be installed on the bottom surface of each hydroponic layer rack 210, and the water outlet is located directly above the hydroponic dish 220. The water discharged from the water outlet can spray fruits and vegetable plants, and the water will remain in the hydroponic dish 220. The water return port can be opened on the bottom surface of the hydroponic dish 220. The hydroponic dish 220 can be provided with planting soil, and the water will soak the planting soil. The excess water will flow back through the water return pipe group, and the water delivery module can reuse the returned water to supply water to the fruits and vegetable plants.

[0042] In some embodiments of the present invention, as Figure 4 shown, the water delivery module at least includes a first water pump 710 and a second water pump 720. The water return module includes a water storage tank 730. The water return pipe group is provided with a return port communicated with each water return port. The water return pipe group is communicated with the water storage tank 730 through the return port. The water storage tank 730 is respectively docked with the first water pump 710 and the second water pump 720. The water delivery pipe group includes a first water pipe group and a second water pipe group. The first water pump 710 is correspondingly arranged with each hydroponic dish 220 on one row of the hydroponic rack body 200 through the first water pipe group. The second water pump 720 is correspondingly arranged with each hydroponic dish 220 on the other row of the hydroponic rack body 200 through the second water pipe group. The control module 600 is electrically connected to the first water pump 710 and the second water pump 720 respectively to control the first water pump 710 and the second water pump 720 to start alternately.

[0043] The hydroponic dishes 220 on multiple hydroponic rack bodies 200 can share a water storage tank 730. When water needs to be provided for the fruits and vegetable plants in the hydroponic dishes 220, the control module 600 can first control the first water pump 710 to start. At this time, the second water pump 720 does not start. The first water pump 710 supplies water to each hydroponic dish 220 on one row of the hydroponic rack body 200 through the first water pipe group. Then, after the water enters each hydroponic dish 220 and is utilized by the vegetables, part of the water will flow back from the hydroponic dish 220 to the water storage tank 730 through the water return pipe group. At this time, the control module 600 controls the second water pump 720 to start and the first water pump 710 to stop. The second water pump 720 supplies water to each hydroponic dish 220 on the other row of the hydroponic rack body 200 through the second water pipe group. Thus, the water storage capacity of the water storage tank 730 can be reduced, the volume of the water storage tank 730 can be reduced, space can be saved, and the floor area can be reduced.

[0044] It can be understood that the number of hydroponic rack bodies 200 can be increased, and the corresponding number of water pumps and water delivery pipes can be configured according to the number of hydroponic rack bodies 200.

[0045] In some embodiments of the present invention, as Figure 1As shown, the first water pipe group includes a first main pipe section 740 and a plurality of first branch pipe sections 750. The first main pipe section 740 is vertically arranged and the first water pump 710 is docked with the first main pipe section 740. The plurality of first branch pipe sections 750 are arranged in one-to-one correspondence with each hydroponic layer rack 210. The head ends of each first branch pipe section 750 are all docked with the first main pipe section 740, and a plurality of water outlets are opened along the length direction of the first branch pipe section 750.

[0046] The first main pipe section 740 serves as the main water supply and then diverts water to each first branch pipe section 750. The first branch pipe sections 750 are arranged at the top of each hydroponic layer rack 210 one by one, and specifically can be arranged at the bottom of the upper hydroponic layer rack 210. The structure is compact and reasonable, the layout is simple, and the complexity of pipeline design is reduced.

[0047] Correspondingly, the second water pipe group includes a second main pipe section and a plurality of second branch pipe sections. The second main pipe section is vertically arranged and the second water pump 720 is docked with the second main pipe section. The plurality of second branch pipe sections are arranged in one-to-one correspondence with each hydroponic layer rack 210. The head ends of each second branch pipe section are all docked with the second main pipe section, and a plurality of water outlets are opened along the length direction of the second branch pipe section.

[0048] In some embodiments of the present invention, as Figure 4 shown, a water level detection module 800 is arranged in the water storage tank 730. The control module 600 is electrically connected to the water level detection module 800. The water level detection module 800 can be selected from a conventional float type water level sensor, a capacitance water level sensor, and a pressure water level sensor. The control module 600 can control the first water pump 710 or the second water pump 720 to start when the water level in the water storage tank 730 reaches the water level threshold, so as to more reasonably and orderly control the alternating operation of the first water pump 710 and the second water pump 720.

[0049] In some embodiments of the present invention, as Figure 3 shown, the return water pipe group includes a return main pipe section 760 and a plurality of return branch pipe sections 770. One end of the return main pipe section 760 is docked with the water storage tank 730. The return main pipe section 760 is arranged along the length direction of the hydroponic rack body 200. The two adjacent hydroponic dishes 220 up and down are connected and communicated through the return branch pipe section 770. The lowermost hydroponic dish 220 is connected and communicated with the return main pipe section 760 through the return branch pipe section 770.

For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
