Description

Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to an air filtration mechanism for a culture box. Background Art

[0002] The air filter plays a vital role in the plant incubator, which directly affects the growth environment and health status of the plants. With the continuous development of modern biotechnology and agricultural technology, the requirements for air quality in the plant incubator are getting higher and higher. The air filter not only needs to filter out dust, microorganisms and other impurities in the air, but also needs to be able to adjust the gas composition in the air as needed, especially the concentration of carbon dioxide and oxygen, to meet the needs of plant photosynthesis and respiration.

[0003] Most of the existing air filtration mechanisms are single-function filtration devices, such as filters with only dust removal or sterilization functions. Although these filters can improve the air quality in the plant incubator to a certain extent, they cannot accurately adjust the gas composition in the air according to the different stages and different needs of plant growth. Especially in the two key processes of photosynthesis and respiration, there are significant differences in the demand of plants for carbon dioxide and oxygen. If the gas composition in the air cannot be adjusted in time, it may affect the normal growth and development of the plant. Therefore, an incubator air filtration mechanism is proposed to solve the above-mentioned problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figure 1-4 , an incubator air filtration mechanism, comprising a connection seat 1, an air inlet 2, a widening block 3 and a conversion fixing component, wherein the air inlet 2 is arranged on one side of the top of the connection seat 1, the widening block 3 is arranged at the lower middle part of the outside of the air inlet 2, and the air inlet 2 and the widening block 3 are jointly provided with a conversion fixing component;

[0028] The conversion and fixing assembly includes a rotating column 8, two composite membranes 9 and a snap-on module 13. The rotating column 8 is located on the outside of the air inlet 2 and is rotatably connected to the middle of the widening block 3 through a bearing. The bottom of the rotating column 8 is also rotatably connected to the connecting seat 1 through a bearing. The rotating column 8 is located on the outer section of the inner section of the widening block 3 and is fixed with a connecting block 7 by external bolts. The two ends of the connecting block 7 are respectively fixed with the outer frame bolts of the two composite membranes 9.

[0029] It should be noted that the material of the two composite membranes 9 can be selected from high molecular polymers, such as polyimide, polytetrafluoroethylene, etc. These materials have excellent gas selective permeability and stability, and can accurately adjust the passage rates of carbon dioxide and oxygen.

[0030] In this embodiment, a support column is welded to the top of the connecting seat 1 and the bottom of the widening block 3 and the end away from the air inlet 2. The air inlet 2 is bolted with an air intake module 4, a coarse filter 5 and a high-efficiency particulate air filter 6 in sequence from top to bottom.

[0031] It should be noted that the coarse filter 5 is usually made of metal mesh or nylon mesh and other materials, which can effectively remove large particles of impurities in the air, such as dust, sand, etc., and protect the subsequent high-efficiency particle air filter 6 from being blocked prematurely. The material of the high-efficiency particle air filter 6 is usually ultra-fine glass fiber paper, which can capture particles larger than 0.3 microns, including bacteria, viruses, mold spores, etc., greatly improving the cleanliness of the air.

[0032] In this embodiment, the air intake module 4 is composed of a connecting ring 401, a cross support frame 402, a motor 403 and a fan blade 404. The connecting ring 401 is fixed to the inner wall near the top of the air inlet 2 by bolts, and the cross support frame 402 is welded to the inside of the connecting ring 401. The motor 403 and the fan blade 404 are respectively arranged at both ends of the cross support frame 402, and the output end of the motor 403 passes through the cross support frame 402 and is fixed to the fan blade 404 by bolts.

[0033] It should be noted that the motor 403 in the air intake module 4 drives the fan blades 404 to rotate, effectively sucking in the outside air. Here, the motor 403 can be a low-noise, high-efficiency DC motor to ensure stable air flow without affecting the plant growth environment.

[0034] In this embodiment, the air inlet 2 and the widening block 3 are jointly provided with a rotating groove whose diameter is greater than the maximum distance between the two composite membranes 9 by 1-3 mm and whose height is 1-3 mm higher than the height of the composite membrane 9. The two composite membranes 9 are respectively a membrane that allows carbon dioxide to pass through while limiting the oxygen permeability and a membrane that allows oxygen to pass through while limiting the carbon dioxide permeability.

[0035] In this embodiment, after the top of the rotating column 8 passes through the widening block 3, the top of the rotating column is widened and two marking blocks 10 are provided on the widened top. Alignment blocks 11 are also provided on both sides of the widened top of the rotating column 8. A horizontal calibration block 12 is provided on the top of the widening block 3 near the alignment block 11 on this side.

[0036] It should be noted that the design of the rotating column 8 allows the composite membrane 9 to be switched by a simple rotation operation, thereby realizing a rapid adjustment of the gas concentration in the incubator. At the same time, the cooperation of the marking block 10 and the alignment block 11 with the calibration block 12 at the top ensures that the composite membrane 9 can be accurately aligned after switching, thereby ensuring the filtering effect.

[0037] In this embodiment, the clamping module 13 includes a connecting ring 1301, four inserting rods 1302 and two holding blocks 1305. The four inserting rods 1302 and the two holding blocks 1305 are respectively welded on both sides of the connecting ring 1301 and are symmetrically distributed.

[0038] In this embodiment, the ends of the insertion rod 1302 are plugged into the outer frames of the air inlet 2 and the composite membrane 9 in turn, a widened column groove is provided at the connection between the inside of the air inlet 2 and the insertion rod 1302, a stopper 1303 is provided outside the insertion rod 1302 and at the bottom of the widened column groove, and a long spring 1304 is also provided outside the insertion rod 1302 and between the stopper 1303 and the top of the widened column groove.

[0039] It should be noted that the design of the plug rod 1302 and the long spring 1304 in the clamping module 13 makes the fixing and replacement process of the composite membrane 9 easier and faster. The material of the plug rod 1302 can be high-strength stainless steel or alloy material to ensure that it will not be deformed or damaged during long-term use. The long spring 1304 provides stable elasticity to ensure the tight connection between the plug rod 1302 and the air inlet 2 and the outer frame of the composite membrane 9.

[0040] Beneficial effects:

[0041] The air filtering mechanism of the incubator drives the fan blades 404 to rotate through the motor 403 in the air intake module 4, thereby effectively inhaling the outside air. The incoming air first passes through the coarse filter 5 to remove large particles of impurities, and then passes through the high-efficiency particle air filter 6 to further filter tiny particles to ensure the cleanliness of the air. At the same time, two composite membranes 9 are connected to the connecting block 7 through the rotating column 8. The two composite membranes have different gas selective permeability properties. One allows carbon dioxide to pass through while limiting the oxygen pass rate, and the other is the opposite. By rotating the rotating column 8, the composite membrane 9 can be easily switched to achieve precise adjustment of the carbon dioxide and oxygen concentrations in the incubator to meet the needs of plant photosynthesis and respiration. The two marking blocks 10 are used to distinguish the two composite membranes 9 to prevent misidentification, while the alignment block 11 and the calibration block 12 are used to ensure that the position after rotation is correct. In addition, the mechanism is also designed with a card connection module 13, including a connecting ring 1301, a plug rod 1302 and a handheld block 1305 and other components. The plug rod 1302 is connected with the air inlet 2 and the outer frame of the composite membrane 9, combined with the elastic effect of the long spring 1304, to achieve rapid fixation and replacement of the composite membrane 9, greatly simplifying the operation process and improving the practicality and convenience of the filtering mechanism.
