Description

Technical Field

[0001] This utility model relates to the technical field of green plant cultivation boxes, specifically a nutrient solution supply device for green plant cultivation boxes. Background Technology

[0002] A plant cultivation box is a container specifically designed for plant growth and is widely used in home gardening, balcony planting, and landscaping.

[0003] According to a public notice regarding a nutrient solution mixing and supply device for cardamom cultivation (Announcement No.: CN220940259U), the aforementioned application includes a first motor, a fixed column, a rotating column, a stirring rod, and a filter tank. These components facilitate the full mixing of the nutrient solution and water. The filter tank is also designed to be easily opened and cleaned by the inclusion of a filter base plate, a connecting ring, a mounting groove, a socket, a mounting block, a receiving groove, a spring, and a limiting block.

[0004] However, in actual use, the above-mentioned equipment often requires different proportions of nutrient solution to be mixed when dealing with different plants. The existing nutrient solution needs to be weighed in a beaker before mixing. When encountering a nutrient solution with a relatively transparent color, it is difficult to accurately observe the exact volume of the nutrient solution, making it difficult for users to accurately dilute the nutrient solution. In view of this, we propose a nutrient solution supply device for green plant cultivation boxes. Utility Model Content

[0005] The purpose of this invention is to provide a nutrient solution supply device for a green plant cultivation box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nutrient solution supply device for a green plant cultivation box, comprising a box body, a mixing tank fixedly connected to the outer wall of the box body, an outlet pipe fixedly connected to the upper outer wall of the mixing tank, a connecting pipe fixedly connected to the outer wall of the mixing tank, and an inlet cylinder fixedly connected to the end of the connecting pipe away from the mixing tank. A metering component is provided inside the inlet cylinder, the metering component comprising:

[0007] A float rod is slidably connected to the inner wall of the feed cylinder. A float plate is fixedly connected to the lower outer wall of the float rod. A limit block is fixedly connected to the outer wall of the float rod. An insert rod is slidably connected through the upper outer wall of the float rod.

[0008] A locking plate is slidably connected to the upper outer wall of the float rod. A locking rod is slidably connected through the outer wall of the float rod. A gas spring is fixedly connected to the upper outer wall of the feed cylinder. A scale plate is fixedly connected to the telescopic end of the gas spring.

[0009] Preferably, the scale plate is provided with a limiting component inside. The limiting component includes a slot, which is formed on the outer wall of the scale plate. An insert plate is slidably connected through the inner wall of the slot. A push plate is fixedly connected to the end of the insert plate away from the slot. A return spring is fixedly connected to the outer wall of the push plate, so that the user can fix the position of the insert rod through the insert plate, thereby making the insert rod stably flush with the zero mark of the scale plate when the scale plate moves.

[0010] Preferably, the end of the return spring away from the push plate is fixedly connected to the end of the scale plate away from the insertion rod. The size of the push plate is larger than the size of the slot, so that when the insertion plate is pushed into the slot of the scale plate, the insertion plate will not fall out of the slot. After the push plate loses its pushing force, the return spring can drive the insertion plate out of the slot.

[0011] Preferably, the lower outer wall of the slot is flush with the zero mark of the scale plate, the length of the insert plate is the same as the distance between the scale plate and the insert rod, and the lower outer wall of the insert plate contacts the upper outer wall of the insert rod. When the insert plate is inserted into the slot, it can push the push plate to make the insert plate pass through the slot. At this time, the insert rod will block the insert plate as it rises.

[0012] Preferably, the inner wall of the locking plate fits against the outer wall of the insertion rod, and a fixing seat is fixedly connected to the upper outer wall of the float rod. The locking rod passes through the fixing seat and contacts the outer wall of the locking plate. When the locking rod passes through the fixing seat, it can push the locking plate to fit against the outer wall of the insertion rod, so that the insertion rod can be fixed at this time. This allows the user to adjust the height of the insertion rod and insert the locking rod to fix the insertion rod when adjusting the height of the scale plate.

[0013] Preferably, a connecting plate is fixedly connected to the outer wall of the float, and a limiting block is fixedly connected to the lower outer wall of the connecting plate. A limiting groove is opened on the outer wall of the feed cylinder, and the limiting block is slidably connected to the inner wall of the limiting groove. When liquid is added to the feed cylinder to make the float plate drive the float to rise, the limiting block can move in the limiting groove, thereby enabling the float to rise stably.

[0014] Preferably, the mixing tank is equipped with a water pump and a mixing trough. The connecting pipe passes through the mixing trough, and a valve is provided at the end of the connecting pipe near the feed cylinder. Water and nutrient solution are added to the feed cylinder, and the mixture can be poured into the mixing trough for mixing.

[0015] Compared with the prior art, this utility model provides a nutrient solution supply device for a green plant cultivation box, which has the following beneficial effects:

[0016] 1. This plant cultivation box uses a nutrient solution supply device. When the liquid is added to the cylinder, the float plate drives the float rod to rise, which in turn drives the insertion rod to measure the scale plate. When encountering a low point, the gas spring can be pushed to raise the scale plate, and then the insertion rod can be raised to the designated position. The locking rod is then inserted, causing the locking rod to push the locking plate to fit against the outer wall of the insertion rod, thus fixing the insertion rod. This allows the height of the insertion rod to be fixed when the height of the scale plate changes, making it easier to observe the liquid level measured by the scale plate.

[0017] 2. The nutrient solution supply device for this green plant cultivation box allows the push plate to pass through the slot when the insertion rod is moved. As the insertion rod rises, it blocks the insertion plate, thus stabilizing the insertion rod at the zero mark on the scale plate. This enables the insertion rod to accurately measure the volume of the liquid. After the push plate loses its pushing force, the return spring causes the insertion plate to leave the slot, allowing the insertion rod to rise stably. Attached Figure Description

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a nutrient solution supply device for a green plant cultivation box, including a box body 1, a mixing box 2 fixedly connected to the outer wall of the box body 1, an outlet pipe 3 fixedly connected to the upper outer wall of the mixing box 2, a connecting pipe 4 fixedly connected to the outer wall of the mixing box 2, and an inlet cylinder 5 fixedly connected to the end of the connecting pipe 4 away from the mixing box 2. A metering component 6 is provided inside the inlet cylinder 5. The metering component 6 includes a float plate 61, a float rod 62, a limiting block 63, an insertion rod 64, a locking plate 65, a locking rod 66, a gas spring 67, and a scale plate 68.

[0024] In one embodiment of this utility model, the float 62 is slidably connected to the inner wall of the feed cylinder 5, the lower outer wall of the float 62 is fixedly connected to the float plate 61, the outer wall of the float 62 is fixedly connected to the limit block 63, and the upper outer wall of the float 62 is slidably connected to the insert rod 64.

[0025] In one embodiment of this utility model, the locking plate 65 is slidably connected to the upper outer wall of the float 62, the outer wall of the float 62 is slidably connected to the locking rod 66, the upper outer wall of the feed cylinder 5 is fixedly connected to the gas spring 67, and the telescopic end of the gas spring 67 is fixedly connected to the scale plate 68.

[0026] In addition, a limiting component 7 is provided inside the scale plate 68. The limiting component 7 includes a slot 74, which is opened on the outer wall of the scale plate 68. An insert plate 73 is slidably connected through the inner wall of the slot 74. A push plate 71 is fixedly connected to the end of the insert plate 73 away from the slot 74. A return spring 72 is fixedly connected to the outer wall of the push plate 71, so that the user can fix the position of the insert rod 64 through the insert plate 73. This allows the insert rod 64 to be stably aligned with the zero mark of the scale plate 68 when the scale plate 68 moves. When the scale plate 68 moves, the float plate 61 can rise with the liquid, allowing the insert rod 64 to accurately measure the volume of the liquid.

[0027] In this embodiment of the present invention, the end of the return spring 72 away from the push plate 71 is fixedly connected to the end of the scale plate 68 away from the insertion rod 64. The size of the push plate 71 is larger than the size of the slot 74, so that when the insertion plate 73 is pushed into the slot 74 of the scale plate 68, the insertion plate 73 will not fall out of the slot 74. After the push plate 71 loses its pushing force, the return spring 72 can drive the insertion plate 73 away from the slot 74, so that the insertion rod 64 can rise stably.

[0028] In this embodiment of the invention, the lower outer wall of the slot 74 is flush with the zero mark of the scale plate 68, the length of the insert plate 73 is the same as the distance between the scale plate 68 and the insert rod 64, and the lower outer wall of the insert plate 73 contacts the upper outer wall of the insert rod 64. When the insert plate 73 is inserted into the slot 74, it can push the push plate 71 to make the insert plate 73 pass through the slot 74. At this time, the insert rod 64 will block the insert plate 73 as it rises, so that the insert rod 64 can be stably positioned on the zero mark of the scale plate 68.

[0029] In this embodiment of the utility model, the inner wall of the locking plate 65 is fitted with the outer wall of the insertion rod 64, and a fixing seat is fixedly connected to the upper outer wall of the float rod 62. The locking rod 66 passes through the fixing seat and contacts the outer wall of the locking plate 65. When the locking rod 66 passes through the fixing seat, it can push the locking plate 65 to fit against the outer wall of the insertion rod 64, so that the insertion rod 64 can be fixed at this time. Thus, when the user adjusts the height of the scale plate 68, he can adjust the height of the insertion rod 64 and insert the locking rod 66 to fix the insertion rod 64, so as to adapt to scale plates 68 of different heights.

[0030] In an embodiment of this utility model, a connecting plate is fixedly connected to the outer wall of the float 62, and a limiting block 63 is fixedly connected to the lower outer wall of the connecting plate. A limiting groove is opened on the outer wall of the feed cylinder 5, and the limiting block 63 is slidably connected to the inner wall of the limiting groove. When liquid is added to the feed cylinder 5 to make the float 61 drive the float 62 to rise, the limiting block 63 can move in the limiting groove, so that the float 62 can rise stably and drive the insertion rod 64 to accurately measure the scale plate 68.

[0031] In an embodiment of this utility model, a water pump is installed inside the mixing tank 2, and a mixing trough is installed inside the mixing tank 2. A connecting pipe 4 passes through the mixing trough, and a valve is installed at one end of the connecting pipe 4 near the feed cylinder 5. Water and nutrient solution are added to the feed cylinder 5. The mixture can be poured into the mixing trough and mixed. Then, the mixture is pumped out from the connecting pipe 4 by the water pump to irrigate the green plants in the tank 1.

[0032] In this invention, when liquid is added to the feed cylinder 5, the float plate 61 drives the float rod 62 to rise. At this time, the limiting block 63 moves in the limiting groove, allowing the float rod 62 to rise stably and drive the insertion rod 64 to accurately measure the scale plate 68. When it is necessary to adjust the scale plate 68 for easier observation, the gas spring 67 can be pushed to raise the scale plate 68. At this time, the insertion rod 64 can be raised to the designated position, and then the locking rod 66 can be inserted, causing the locking rod 66 to push the locking plate 65 to fit against the outer wall of the insertion rod 64, thus fixing the insertion rod 64. Therefore, when the height of the scale plate 68 changes, the height of the insertion rod 64 can be adjusted accordingly. The fixed position allows for easier observation of the liquid height measured by the scale plate 68. When moving the insertion rod 64, the push plate 71 can be pushed to allow the insertion plate 73 to pass through the slot 74. At this time, the insertion rod 64 will block the insertion plate 73 as it rises, thus allowing the insertion rod 64 to be stabilized at the zero mark of the scale plate 68. This enables the insertion rod 64 to accurately measure the volume of the liquid. After the water and nutrient solution are added to the feed cylinder 5 to the specified amount, the water valve can be opened to allow the mixture to be poured from the connecting pipe 4 into the mixing tank for mixing. Then, the mixture is pumped out from the connecting pipe 4 and sprayed from the outlet pipe 3 to irrigate the plants inside the box 1.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
