[0035] The second embodiment of the present application is:

[0036] Based on the first embodiment, please refer to Figure 5-Figure 8 ,in, Figure 5 is a cross-sectional view of a second embodiment of the present invention. Figure 6 yes Figure 5 A partial enlargement of detail B. Figure 7 is another cross-sectional view of the second embodiment of the present invention. Figure 8 yes Figure 7 A partial enlargement of detail C.

[0037] A plant cultivation device provided by the present invention also includes a splash-proof component 201; the splash-proof component 201 includes two telescopic rods 202, a water receiving box 203, a drainage pipe 204, a first magnet 205 and a second magnet 206; the telescopic rod 202 includes a mounting tube 207 and a sliding rod 208.

[0038] According to this specific embodiment, a plurality of splash-proof components 201 are respectively arranged inside the cabinet 101. If the cultivation tray 106 in the middle layer is taken away, the nutrient solution in the second liquid outlet pipe 109 in the upper layer directly falls into the transfer box 108 in the middle layer, and then passes through the second liquid outlet pipe 109 in the middle layer, the cultivation tray 106 in the lower layer, the first liquid outlet pipe 107 in the lower layer, the transfer box 108 in the lower layer, the second liquid outlet pipe 109 in the lower layer, and finally returns to the liquid storage tank 103; however, when in use, there is a large distance between the second liquid outlet pipe 109 in the upper layer and the transfer box 108 in the middle layer, and when the nutrient solution falls from the second liquid outlet pipe 109 in the upper layer to the transfer box 108 in the middle layer, it is easy to splash out from the transfer box 108 in the middle layer, so the splash-proof component 201 is provided.

[0039] Among them, the two telescopic rods 202 are fixedly connected to the cabinet 101 respectively and are respectively located inside the cabinet 101; the water receiving box 203 is fixedly connected to the two telescopic rods 202 respectively and is located on one side of the two telescopic rods 202; the drain pipe 204 is connected to the water receiving box 203 and is located at the bottom of the water receiving box 203; the first magnet 205 is fixedly connected to the water receiving box 203 and is located on the side of the water receiving box 203; the second magnet 206 is fixedly connected to the disk body 112 and is located on the side of the disk body 112. The two telescopic rods 202 can be telescopic, so the water receiving box 203 can be displaced in the sliding direction of the cultivation tray 106. During normal use, the first magnet 205 adsorbs the second magnet 206, and the water receiving box 203 is located on the side of the cultivation tray 106. Taking the cultivation tray 106 in the middle layer as an example, if the cultivation tray 106 in the middle layer is taken out, the cultivation tray 106 in the middle layer will be slid out through the first magnet 205 and the second magnet 206, which will drive the water receiving box 203 to move until the water receiving box 203 moves to the bottom of the second liquid outlet pipe 109 in the upper layer, and at the same time, the drain pipe 204 is aligned with the transfer box 108 in the middle layer. At this time, the telescopic rod 20 2 cannot be extended any further, and when the cultivation tray 106 is continuously slid out, the first magnet 205 and the second magnet 206 are separated; at this time, the water receiving box 203 and the drain pipe 204 are placed between the second liquid outlet pipe 109 at the upper layer and the transfer box 108 at the middle layer, and the nutrient solution flowing out of the second liquid outlet pipe 109 at the upper layer first enters the adjacent water receiving box 203, and then flows out from the drain pipe 204 and falls into the adjacent transfer box 108 at the middle layer, thereby avoiding the splashing of the nutrient solution; when the cultivation tray 106 at the middle layer is slid back, the cultivation tray 106 will push the water receiving box 203 to reset, and at the same time, the first magnet 205 and the second magnet 206 are adsorbed together.

[0040] Secondly, the installation tube 207 is fixedly connected to the cabinet 101 and is located inside the cabinet 101; the slide bar 208 is slidably connected to the installation tube 207, and is fixedly connected to the water receiving box 203 and is located inside the installation tube 207. The installation tube 207 is used for slidably installing the slide bar 208, and the slide bar 208 can slide in the installation tube 207, and the sliding distance is limited. The two slide bars 208 support the water receiving box 203.

[0041] In the plant cultivation device described in this embodiment, the two telescopic rods 202 can be extended and retracted, so the water receiving box 203 can be displaced in the sliding direction of the cultivation tray 106. During normal use, the first magnet 205 adsorbs the second magnet 206, and the water receiving box 203 is located on the side of the cultivation tray 106. Taking the cultivation tray 106 in the middle layer as an example, if the cultivation tray 106 in the middle layer is taken out, the cultivation tray 106 in the middle layer will be slid out through the first magnet 205 and the second magnet 206, which will drive the water receiving box 203 to move until the water receiving box 203 moves to the bottom of the second liquid outlet pipe 109 in the upper layer, and at the same time, the drain pipe 204 is aligned with the transfer box 108 in the middle layer. When the telescopic rod 202 can no longer be extended, and when the cultivation tray 106 is continuously slid out, the first magnet 205 and the second magnet 206 are separated; at this time, the water receiving box 203 and the drain pipe 204 are placed between the second liquid outlet pipe 109 on the upper layer and the transfer box 108 on the middle layer, and the nutrient solution flowing out of the second liquid outlet pipe 109 on the upper layer first enters the adjacent water receiving box 203, and then flows out from the drain pipe 204 and falls into the adjacent transfer box 108 on the middle layer, thereby avoiding the splashing of the nutrient solution; when the cultivation tray 106 on the middle layer is slid back, the cultivation tray 106 will push the water receiving box 203 to reset, and at the same time, the first magnet 205 and the second magnet 206 are adsorbed together.

[0042] The third embodiment of the present application is:

[0043] Based on the second embodiment, please refer to Figure 9-10 ,in, Fig. 9 It is a schematic structural diagram of the third embodiment of the present invention. Fig.10 yes Fig. 9 A partial enlargement of detail D.

[0044] The plant cultivation device provided by the present invention further includes a plurality of protection components 301 ; the protection components 301 include an L-shaped baffle 302 and an L-shaped block 303 .

[0045] According to this specific embodiment, a plurality of protection components 301 are respectively arranged on the cabinet 101. When the cultivation tray 106 is placed in the cabinet 101, there is no limit protection in front, and the cultivation tray 106 is easy to slide out and fall, so two protection components 301 are arranged for each layer of the cultivation tray 106 for limit.

[0046] The L-shaped baffle 302 is fixedly connected to the cabinet 101 and is located at one side of the cabinet 101; the L-shaped stopper 303 is rotatably connected to the cabinet 101 and is located at one side of the cabinet 101.
