For individual users, this way of obtaining CO2 is neither economical nor convenient. Summary of the Utility Model

[0035] Embodiment 1:

[0036] As Figure 1 shown, a CO2 adsorption and desorption enrichment device includes:

[0037] A housing 3; an air inlet is provided at the bottom end of the housing 3, and an air outlet is provided at the top end of the housing 3;

[0038] Two fans 2; one fan 2 is arranged in the air inlet, and the other fan 2 is arranged in the air outlet. The fan 2 is used to accelerate the external air flowing through the inside of the housing 3, so that the air contacts the CO2 adsorption material 6;

[0039] A CO2 adsorption mechanism; the CO2 adsorption mechanism includes an adsorption container and a CO2 adsorption material 6. When the CO2 adsorption material 6 is not heated, the CO2 adsorption material 6 adsorbs CO2 in the air. When the CO2 adsorption material 6 is heated, the CO2 adsorption material 6 releases the adsorbed CO2. The CO2 adsorption material 6 is filled in the adsorption container according to a preset ratio. The adsorption container is arranged inside the housing 3, and the adsorption container is a breathable structure;

[0040] A driving mechanism; the driving mechanism is arranged inside the housing 3. The driving mechanism is provided with a rotating shaft, and the adsorption container is fixedly connected to the rotating shaft. The driving mechanism is used to drive the adsorption container to rotate;

[0041] A heating mechanism; the heating mechanism is arranged inside the housing 3, and the heating mechanism is used to heat the CO2 adsorption material 6;

[0042] A one-way valve 11; the one-way valve 11 is installed on the housing 3. The gas input end of the one-way valve 11 points to the inside of the housing 3, and the gas output end of the one-way valve 11 points to the outside of the housing 3;

[0043] Two openable and closable sealing mechanisms 1; the two sealing mechanisms 1 are respectively used to seal and unseal the air inlet and the air outlet;

[0044] A control module; the fan 2, the one-way valve 11, the heating mechanism and the sealing mechanism 1 are all connected to the control module. When the CO2 adsorption material 6 needs to adsorb CO2, the control module controls the sealing mechanism 1 to unseal and starts the fan 2. When the CO2 adsorption material 6 needs to release CO2, the control module controls the sealing mechanism 1 to seal, turns off the fan 2, starts the heating mechanism, and controls the opening time, opening interval and opening threshold of the one-way valve 11. The control module includes a microcontroller or a processor, a memory, and an input / output interface.

[0045] In this embodiment, the present application is provided with a mechanism for CO2 adsorption and CO2 release. When the CO2 adsorption material 6 is required to adsorb CO2, the control module controls the unsealing of the sealing mechanism 1 and starts the fan 2. The fan 2 accelerates the external air to flow through the housing 3. At this time, the CO2 adsorption material 6 contacts the air and adsorbs CO2 at room temperature. When the adsorption process ends and the CO2 adsorption material 6 is required to release CO2, the control module controls the sealing mechanism 1 to seal, turns off the fan 2, and starts the heating mechanism to heat the CO2 adsorption material 6. At this time, the CO2 adsorption material 6 starts to release CO2. As CO2 is released, the air pressure inside the housing 3 gradually rises. At this time, the control module can control the opening time and opening interval of the one-way valve 11 to achieve continuous and timed release of CO2.

[0046] Compared with the traditional CO2 acquisition method, the present application is provided with a driving structure to continuously rotate the CO2 adsorption mechanism, making the CO2 adsorption material contact the air more comprehensively and being heated more evenly, improving the efficiency of CO2 adsorption and release. Using the present application can increase the proportion of CO2 per unit volume and achieve the enrichment effect of CO2. Moreover, the present application is more economical and convenient, and can meet the CO2 requirements in mosquito trapping and agricultural production.

[0047] Embodiment 2:

[0048] The difference between this embodiment and Embodiment 1 is that the CO2 adsorption material 6 is granular, the housing of the adsorption container is a mesh structure, and the mesh diameter of the housing of the adsorption container is smaller than the diameter of a single particle of the CO2 adsorption material 6.

[0049] In this embodiment, as Figure 1 shown, the adsorption container includes a tray 8 and a grid 7. The CO2 adsorption material 6 is filled in the tray 8. The bottom of the tray 8 is a mesh structure, and the mesh diameter of the bottom of the tray 8 is smaller than the diameter of a single particle of the CO2 adsorption material 6. The grid 7 is arranged in the tray 8, and the CO2 adsorption material 6 is evenly distributed in the grids of each grid 7;

[0050] In addition, the adsorption container can also be a spherical structure. The housing of the spherical adsorption container is a mesh structure, and the mesh diameter of the housing of the spherical adsorption container is smaller than the diameter of a single particle of the CO2 adsorption material 6. The filling volume of the CO2 adsorption material 6 is less than 90% of the volume of the spherical adsorption container. When the spherical adsorption container is driven by a driving mechanism to rotate, the particles of the CO2 adsorption material 6 filled inside it will all roll, and each particle of the CO2 adsorption material 6 can be in full contact with the air and be heated evenly, finally achieving the effect of improving the CO2 adsorption and release efficiency.

[0051] In addition, the adsorption container can also be a wheel-shaped structure. A grid chamber is provided at the outer wheel edge of the wheel-shaped structure. The mesh diameter of the grid chamber is smaller than the diameter of a single particle of the CO2 adsorption material 6. The axle of the wheel-shaped structure is connected to the rotating shaft of the driving mechanism, and the driving structure can drive the adsorption container of the wheel-shaped structure to rotate along the axle.

[0052] Example 3:

[0053] The difference between this example and Example 2 is that, as Figure 1 shown, the heating mechanism includes:

[0054] Two semiconductor temperature control chips 5; the semiconductor temperature control chips 5 are arranged at the bottom of the grid, and the tray 8 is arranged above the semiconductor temperature control chips 5;

[0055] The first electric wire; one end of the first electric wire is connected to the semiconductor temperature control chip 5, and the other end of the first electric wire passes through the housing 3 and is connected to the control module.

[0056] In this example, the semiconductor temperature control chip 5 is a PTC ceramic chip. The PTC ceramic chip can switch between heating and cooling by changing the direction of the current inside it. In this application, the CO2 adsorption and CO2 release can be alternately cycled through the control module. When entering the CO2 adsorption process, the control module controls the sealing mechanism 1 to unseal and starts the fan 2. The fan 2 accelerates the external air to flow through the housing 3. At this time, the CO2 adsorption material 6 contacts the air and adsorbs CO2 at room temperature. After reaching the preset adsorption time, it enters the CO2 release process. The control module controls the sealing mechanism 1 to seal, closes the fan 2, and starts the semiconductor temperature control chip 5 to heat the CO2 adsorption material 6. At this time, the CO2 adsorption material 6 starts to release CO2. As the CO2 is released, the air pressure inside the housing 3 gradually rises. At this time, the control module controls the opening time and opening interval of the one-way valve 11 to achieve continuous CO2 release. After reaching the preset release time, it enters the CO2 adsorption process again. The control module controls the sealing mechanism 1 to unseal and starts the fan 2. The fan 2 accelerates the external air to flow through the housing 3. At this time, the direction of the current inside the semiconductor temperature control chip 5 is changed to make the semiconductor temperature control chip 5 refrigerate and quickly reduce the temperature of the CO2 adsorption material 6. At this time, the CO2 adsorption material 6 contacts the air and adsorbs CO2.

[0057] Repeating the above process can improve the adsorption efficiency and release efficiency.

[0058] Example 4:

[0059] The difference between this example and Example 2 is that, as Figure 1 shown, the rotating mechanism is a motor 4. The motor 4 is fixedly installed inside the housing 3, and the top of the transmission shaft of the motor 4 is fixedly connected to the center of gravity point of the bottom surface of the tray 8.

[0060] Example 5:

[0061] The difference between this embodiment and Embodiment 1 is that, as Figure 1 shown, the enrichment device further includes a gas collection mechanism, which is connected to the one-way valve 11 and is used to collect the output gas of the one-way valve 11.

[0062] In this embodiment, the gas collection mechanism is used for the storage and transportation of CO2.

[0063] Embodiment 6:

[0064] The difference between this embodiment and Embodiment 5 is that, as Figure 1 shown, the gas collection mechanism includes:

[0065] A gas guide pipe 10; the first end of the gas guide pipe 10 is communicated with the gas output end of the one-way valve 11;

[0066] A gas storage tank 9; the second end of the gas guide pipe 10 is communicated with the gas input end of the gas storage tank 9.

[0067] Embodiment 7:

[0068] The difference between this embodiment and Embodiment 2 is that, as Figure 1 shown, the CO2 adsorption material 6 is a DAC technology material, such as the carbon dioxide capture material for mosquito trapping equipment involved in the patent with the patent number ZL202410482343.X.

[0069] Embodiment 8:

[0070] The difference between this embodiment and Embodiment 1 is that, as Figure 1 shown, both of the two sealing mechanisms 1 are electric valves, and the electric valves are both connected to the control module.

[0071] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
