Technical Field

[0001] The utility model relates to the field of plant growth chambers, in particular to a controllable CO2 plant growth chamber. Background Art

[0002] A plant growth chamber is a plant cultivation device that provides variable conditions such as temperature, humidity and light suitable for plant growth within a certain space. It is generally used for plant cultivation and growth promotion.

[0003] Existing plant growth chambers generally contain supply equipment for resources such as light and water required for plant growth. The carbon dioxide required for plant photosynthesis is generally maintained by introducing air to exhaust the oxygen produced by plant photosynthesis in the chamber to maintain the carbon dioxide concentration in the chamber. Some plant growth chambers also directly inject carbon dioxide gas into the chamber.

[0004] With respect to the above-mentioned related technologies, in actual use, the existing plant growth chambers use air circulation to exhaust the air in the chamber and continuously introduce fresh air into the chamber, which makes it difficult to maintain a high concentration of carbon dioxide content in the chamber. The method of directly introducing high-concentration carbon dioxide into the chamber easily causes uneven distribution of carbon dioxide in the chamber, resulting in the plants in the chamber being unable to obtain the growth conditions of the proper carbon dioxide concentration. In summary, it is difficult for the existing plant growth chambers to evenly control the carbon dioxide concentration in the chamber structure. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a controllable CO2 plant growth chamber to solve the technical problem that the existing plant growth chamber is difficult to evenly control the carbon dioxide concentration in the chamber structure.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a controllable CO2 plant growth box, comprising a base, a box body fixedly connected to the base, multiple layers of culture platforms arranged in the box body in a vertical direction, an air duct including all the culture platforms fixedly connected to the box body, an air supply pipe passing through the multiple layers of culture platforms fixedly connected to the top of the base, an air supply pipe is provided with an air jet disk above each layer of culture platforms, a plurality of air jet heads are connected to the air jet disk along a circumferential direction, a carbon dioxide gas cylinder is connected to the bottom end of the air supply pipe, an air inlet is provided on one side of each culture platform of the air duct, and an air outlet is provided on the other side, a fan assembly is provided at the bottom end of the air duct near the air inlet, a ventilation strip is provided on the side away from the fan assembly, a wind shield structure is provided at the air inlet of the air duct, and a one-way ventilation structure is provided at the air outlet.

[0007] By adopting the above technical solution, the carbon dioxide sprayed by the nozzle is mixed with external air to achieve convenient adjustment of the carbon dioxide concentration in the box, and the carbon dioxide concentration of each layer of the plant culture platform in the box can be adaptively adjusted to provide a better growth environment for the plants.

[0008] The utility model is further configured such that the air inlets are rectangular in structure and are arranged at equal intervals along the length direction of the culture platform.

[0009] By adopting the above technical solution, the concentration of carbon dioxide can be easily adjusted by controlling the gas inflow at the air inlet.

[0010] The utility model is further configured that the inner wall of the air duct is provided with mutually parallel guide rails at the upper and lower ends of the air inlet, and a baffle is slidably connected in the guide rail, and the baffle is used to shield the air inlet.

[0011] By adopting the above technical solution, the gas flux at the air inlet can be conveniently adjusted through the sliding baffle structure.

[0012] The utility model is further configured such that the air outlets are in a rectangular structure and are arranged at equal intervals along the height direction of the culture platform.

[0013] By adopting the above technical solution, the air pressure in the plant planting space inside the box increases, and the oxygen produced by plant photosynthesis is mixed with air and conveniently discharged from the air outlet.

[0014] The utility model is further configured that the outer wall of the air duct is rotatably connected with a blocking bar for shielding the air outlet at a position close to the air outlet.

[0015] By adopting the above technical solution, the gas in the culture platform can be smoothly discharged into the air duct, while the gas between the air duct and the inner wall of the box cannot smoothly enter the space above the culture platform through the air outlet.

[0016] The utility model is further configured that one end of the baffle is connected to a telescopic rod, and the telescopic rod is installed on the inner wall of the air duct.

[0017] By adopting the above technical solution, the sliding amount of the baffle is controlled by using the telescopic rod, thereby conveniently achieving the control of the gas flux at the air inlet.

[0018] The utility model is further configured such that the adjacent jet heads on the jet disc are respectively inclined upward and downward.

[0019] By adopting the above technical solution, the carbon dioxide gas in the gas supply pipe can be sprayed into the space above the culture platform more evenly and efficiently.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] The utility model arranges an air duct structure in the box, and arranges a carbon dioxide injection head at each layer of the plant culture platform, so that the carbon dioxide in the carbon dioxide compressed gas cylinder in the base is passed into the plant culture platform on each layer, and the air intake is controlled by a slide plate on one side of the air duct structure, and the carbon dioxide injected by the injection head is mixed with external air to realize convenient adjustment of the carbon dioxide concentration in the box, and can realize adaptive adjustment of the carbon dioxide concentration of the plant culture platforms on each layer in the box, thereby providing a better growth environment for the plants.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1

[0033] A controllable CO2 plant growth chamber, such as Figure 1-8 As shown, it includes a base 1, a box body 2 is fixedly connected to the base 1, and a variety of plant growth protection equipment commonly used in the prior art such as lighting and water supply are arranged in the box body 2. Multi-layer culture platforms 5 are arranged in the vertical direction in the box body 2, and each culture platform 5 is provided with a plurality of sensors for detecting carbon dioxide concentration. An air duct 6 including all the culture platforms 5 is fixedly connected in the box body 2. Specifically, the air duct is in an inverted concave shape, and it and the inner wall of the box body 2 together form a passage for gas flow. The top of the base 1 is fixedly connected to an air supply pipe 13 that passes through the multi-layer culture platform 5. The air supply pipe 13 is arranged at each layer of the culture platform 5. A jet disk 14 is provided above the culture platform 5, and a plurality of jet heads 15 are connected to the jet disk 14 along a circumferential direction. A carbon dioxide cylinder is connected to the bottom end of the air supply pipe 13. An air inlet 7 is provided on one side of each culture platform 5 of the air duct 6, and an air outlet 8 is provided on the other side. A fan assembly 3 is provided at the bottom of the air duct 6 near the air inlet 7 of the box body 2. Specifically, the fan assembly 3 includes a plurality of groups of fans connected in parallel with each other and blowing in the direction of the air duct 6. A breathable strip 4 is provided on the side away from the fan assembly 3. The air duct 6 is provided with a wind shield structure at the air inlet 7, and a one-way ventilation structure at the air outlet 8.

[0034] See also Figure 2-8 The air outlet 8 is of a rectangular structure and is equidistantly arranged along the height direction of the culture platform 5. The air pressure in the plant planting space in the box body 2 increases, and the oxygen produced by plant photosynthesis is mixed with air and conveniently discharged from the air outlet 8. The outer wall of the air duct 6 is rotatably connected to a baffle 12 for blocking the air outlet 8 at a position close to the air outlet 8. Since the baffle 12 can only rotate in a direction away from the air duct 6, a one-way ventilation effect is achieved at the air outlet 8, so that the gas in the culture platform 5 can be smoothly discharged into the air duct 6, while the gas between the air duct 6 and the inner wall of the box body 2 cannot smoothly pass through the air outlet 8 into the space above the culture platform 5.

[0035] See also Figure 2-8The air inlet 7 is of a rectangular structure and is arranged at equal intervals along the length direction of the culture platform 5. The airflow flowing into the plant planting space in the box body 2 at the air inlet 7 is mixed with high-concentration carbon dioxide gas. The carbon dioxide concentration can be easily adjusted by controlling the gas inflow at the air inlet 7. The inner wall of the air duct 6 is provided with mutually parallel guide rails 9 at the upper and lower ends of the air inlet 7. A baffle 10 is slidably connected in the guide rail 9. Specifically, the baffle 10 is provided with gaps that are the same as those of the air inlet 7 at intervals, so that the baffle 10 can slide to cover the air. It can block the air inlet 7 and can also slide to align the notch with the air inlet 7. The baffle 10 is used to block the air inlet 7. The gas flux at the air inlet 7 can be conveniently adjusted through the sliding baffle structure. One end of the baffle 10 is connected to a telescopic rod 11. Specifically, the telescopic rod 11 includes a telescopic part fixedly connected to the baffle 10 and a fixed part fixedly connected to the inner wall of the air duct 6. The telescopic rod 11 is installed on the inner wall of the air duct 6. The telescopic rod 11 is used to control the sliding amount of the baffle 10, thereby conveniently realizing the control of the gas flux at the air inlet 7. Embodiment 2

[0036] A controllable CO2 plant growth chamber, such as Figure 1-8 As shown, on the basis of Example 1, the difference from Example 1 lies in that the adjacent nozzles 15 on the jet disk 14 are tilted upward and downward respectively. Specifically, the jet disk 14 is located in the middle of the air supply pipe 13 above the culture platform 5, and can occasionally introduce the carbon dioxide gas passing through the air supply pipe 13 into the nozzle head 15, so that the gas in the carbon dioxide gas tank located in the base 1 flows along the air supply pipe 13 to the jet disk 14, and then passes through the jet disk 14 and is ejected from the nozzle head 15, so that the carbon dioxide gas in the air supply pipe 13 can be more evenly and efficiently sprayed into the space above the culture platform 5.

[0037] The working principle of the utility model is as follows: the fan in the fan assembly 3 works, and at the same time, after the telescopic rods 11 at each layer of the culture platform 5 adjust the telescopic amount, the outside air is blown into the air duct 6, and while flowing along the air duct 6, it flows into the space above the inverted culture platform 5 from the air inlet 7, and the carbon dioxide gas in the carbon dioxide storage tank in the base 1 enters the space above the inverted culture platform 5 through the air supply pipe 13 and the guidance of the jet disk 14 and the jet head 15, and after being fully mixed with the air passing through the air inlet 7, the carbon dioxide concentration of the plant planting environment can be conveniently adjusted, the air pressure in the space above the culture platform 5 increases, the baffle 10 at the air outlet 8 is blown up, and the oxygen generated by plant photosynthesis flows through the air outlet 8 driven by the air flow and is discharged from the box body 2 from the air permeable strip 4.

[0038] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
