[0039] Combined with Figure 1-2As shown, in some embodiments, a device for removing carbon dioxide includes: a housing 100, an air flow switch assembly 200, an adsorption module 300, and a heating device 400. The housing 100 includes a first air outlet 500 communicating with the interior of the room and a second air outlet 600 communicating with the exterior of the room; the air flow switch assembly 200 is configured to open the first air outlet 500 and close the second air outlet 600 in a first state, and close the first air outlet 500 and open the second air outlet 600 in a second state.

[0040] By using the device for removing carbon dioxide disclosed in this embodiment, the carbon dioxide in the indoor air can be adsorbed by the adsorption module 300 disposed inside the housing 100. Due to the characteristic that the adsorption module 300 adsorbs carbon dioxide at normal temperature and releases carbon dioxide in a heated state, the adsorption module 300 is intermittently heated by the heating device 400, and the carbon dioxide released by the adsorption module 300 is discharged to the outside through the second air outlet 600, effectively removing the carbon dioxide in the indoor air and improving the user experience.

The first switching valve 210 is disposed inside the first air outlet 500; the second switching valve 220 is disposed inside the second air outlet 600. In this way, by controlling the first switching valve 210 to open and the second switching valve 220 to close, the first air outlet 500 is opened and the second air outlet 600 is closed, or by controlling the first switching valve 210 to close and the second switching valve 220 to open, the first air outlet 500 is closed and the second air outlet 600 is opened, so that the air treated by adsorption is discharged into the room through the first air outlet 500, and the carbon dioxide released by the adsorption module 300 is discharged to the outside through the second air outlet 600, effectively removing the carbon dioxide in the indoor air and improving the user experience.

[0043] Optionally, in the first state, the first switching valve 210 is opened and the second switching valve 220 is closed. In this way, when in the first state, the first air outlet 500 is opened and the second air outlet 600 is closed, and the air after adsorption treatment in the housing 100 is discharged into the room, reducing the carbon dioxide content in the indoor air.

[0044] Optionally, in the second state, the first switching valve 210 is closed and the second switching valve 220 is opened. In this way, when in the second state, the first air outlet 500 is closed and the second air outlet 600 is opened, and the carbon dioxide released by the adsorption module 300 is discharged outdoors, effectively removing the carbon dioxide in the indoor air and improving the user experience.

[0045] Optionally, in the case corresponding to the first state, the heating device 400 is turned off. In this way, the adsorption module 300 is in a normal temperature state and will adsorb the carbon dioxide in the air flowing through the adsorption module 300, effectively removing the carbon dioxide in the indoor air.

[0046] Optionally, in the case corresponding to the second state, the heating device 400 is turned on. In this way, the adsorption module 300 is heated and will release the carbon dioxide it adsorbs, and the released carbon dioxide is discharged outdoors, effectively removing the carbon dioxide in the indoor air.

[0047] Combined with Figure 3-6 As shown, in some optional embodiments, the air flow switch assembly 200 includes: a baffle 700. The baffle 700 is configured to open the first air outlet 500 and close the second air outlet 600 when in the first position, and close the first air outlet 500 and open the second air outlet 600 when in the second position. In this way, by controlling the baffle 700 to switch between the first position and the second position, the air after adsorption treatment is discharged into the room through the first air outlet 500, and the carbon dioxide released by the adsorption module 300 is discharged outdoors through the second air outlet 600, facilitating the discharge of the air flow and effectively removing the carbon dioxide in the indoor air.

[0048] Optionally, the device for removing carbon dioxide further includes: a driving device 800. The driving device 800 is connected to the baffle 700 and is configured to drive the baffle 700 to switch between the first position and the second position. In this way, the setting of the driving device 800 facilitates driving the baffle 700 to switch between the first position and the second position, facilitating the air flow after adsorption treatment to be discharged into the room through the first air outlet 500, and the carbon dioxide released by the adsorption module 300 to be discharged outdoors through the second air outlet 600, effectively removing the carbon dioxide in the indoor air.

[0049] Optionally, the apparatus for removing carbon dioxide further includes: an air outlet cavity 710. The air outlet cavity 710 is disposed on the housing 100 and is in communication with the housing 100. The baffle 700 is movably disposed within the air outlet cavity 710. In this way, the airflow within the housing 100 first enters the air outlet cavity 710 and then is discharged from the first air outlet 500 or the second air outlet 600 through the adjustment of the baffle 700, facilitating the discharge of the airflow.

[0050] Optionally, both the first air outlet 500 and the second air outlet 600 are disposed on the air outlet cavity 710. The first air outlet 500 communicates the air outlet cavity 710 with the interior of the room, and the second air outlet 600 communicates the air outlet cavity 710 with the exterior of the room. In this way, the airflow within the air outlet cavity 710 that has been adsorbed and processed is discharged into the room through the first air outlet 500, and the carbon dioxide released by the adsorption module 300 within the air outlet cavity 710 is discharged to the exterior of the room through the second air outlet 600, facilitating the discharge of the airflow within the air outlet cavity 710 and effectively removing carbon dioxide from the indoor air.

[0051] Optionally, in the first state, the baffle 700 is in the first position, and in the second state, the baffle 700 is in the second position. In this way, in the first state, the baffle 700 opens the first air outlet 500 and closes the second air outlet 600, facilitating the discharge of the adsorbed and processed airflow into the room. In the second state, the baffle 700 closes the first air outlet 500 and opens the second air outlet 600, facilitating the discharge of the carbon dioxide released by the adsorption module 300 to the exterior of the room.

[0052] Optionally, the baffle 700 includes: a plurality of flow guiding vanes 720. In the case where the baffle 700 is in the first position, some of the flow guiding vanes 720 close the second air outlet 600, and the remaining flow guiding vanes 720 guide the airflow flowing through the first air outlet 500. In this way, when the baffle 700 is in the first position and the adsorption module 300 is in a normal temperature state, the adsorption module 300 adsorbs the carbon dioxide in the air flowing through it, and then discharges the adsorbed and processed airflow into the room through the first air outlet 500. At this time, some of the flow guiding vanes 720 close the second air outlet 600 to prevent the adsorbed and processed airflow from being discharged to the exterior of the room, and the remaining flow guiding vanes 720 guide the airflow flowing through the first air outlet 500, enabling the direction of the airflow blown out from the first air outlet 500 to be adjustable, making the air outlet more uniform, increasing the air outlet range, and improving the user experience.

[0053] Optionally, one end of the flow guiding vane 720 is provided with a first shaft arm 721, and the other end is provided with a second shaft arm 722, and it is movably installed within the air outlet cavity 710 through the first shaft arm 721 and the second shaft arm 722. In this way, it is convenient for the installation of the flow guiding vanes 720, and the installed flow guiding vanes 720 are easy to rotate and adjust, with strong stability.

[0054] Optionally, the driving device 800 includes: a crank lever 810, a motor, and a connecting rod 820. There are multiple crank levers 810, and some of the crank levers 810 are connected to the output end of the motor, and the remaining crank levers 810 are connected to the first shaft arm 721 of the guide vane 720. All the multiple crank levers 810 are connected to the connecting rod 820. In this way, by driving the crank lever 810 connected to the output end of the motor to rotate, the crank lever 810 connected to the first shaft arm 721 of the guide vane 720 is driven to rotate through the connecting rod 820, and then the rotation of the guide vane 720 is uniformly driven by the motor, so that the guide vane 720 rotates in the air outlet cavity 710, opening the first air outlet 500 and closing the second air outlet 600 or closing the first air outlet 500 and opening the second air outlet 600.

[0055] Optionally, the crank lever 810 is a crank-shaped rod structure, and one end is fixedly connected to the output end of the motor or the first shaft arm 721 of the guide vane 720, and the other end is rotatably connected to the connecting rod 820. In this way, since one end of the crank lever 810 is fixedly connected to the output end of the motor or the first shaft arm 721 of the guide vane 720, the crank lever 810 can be driven to rotate by the output end of the motor, or the guide vane 720 can be driven to rotate by the crank lever 810. Since the other end of the crank lever 810 is rotatably connected to the connecting rod 820, relative rotation can occur between the crank lever 810 and the connecting rod 820, which is convenient for driving the crank lever 810 by the connecting rod 820 and facilitating the driving of the crank lever 810 connected to the guide vane 720.

[0056] Optionally, the crank lever 810 includes: a first crank lever 811, a second crank lever 812, a third crank lever 813, and a fourth crank lever 814. The first crank lever 811 and the second crank lever 812 are both connected to the output end of the motor; the third crank lever 813 and the fourth crank lever 814 are both connected to the first shaft arm 721 of the guide vane 720. In this way, the first crank lever 811 and the second crank lever 812 are driven to rotate by the output end of the motor, and the rotating first crank lever 811 and second crank lever 812 drive the third crank lever 813 and the fourth crank lever 814 to rotate through the connecting rod 820, thereby driving the guide vane 720 connected to the third crank lever 813 and the fourth crank lever 814, so that the guide vane 720 rotates in the air outlet cavity 710, opening the first air outlet 500 and closing the second air outlet 600 or closing the first air outlet 500 and opening the second air outlet 600.

[0057] Optionally, when the baffle 700 is in the first position, the first shaft arm 721 of the deflector 720 that closes the second air outlet 600 is connected to the third crank 813, and the first shaft arm 721 of the deflector 720 that guides the airflow flowing through the first air outlet 500 is connected to the fourth crank 814. In this way, when the baffle 700 is in the first position, a part of the deflector 720 is driven by the third crank 813 to close the second air outlet 600, and the remaining part of the deflector 720 is driven by the fourth crank 814 to guide the airflow flowing through the first air outlet 500, so that the deflector 720 closing the second air outlet 600 and the deflector 720 guiding the airflow flowing through the first air outlet 500 are driven by different cranks 810.

[0058] Optionally, the motor includes: a first motor 830 and a second motor 840. The output end of the first motor 830 is connected to the first crank 811, and the first crank 811 and the third crank 813 are connected by a connecting rod 820; the output end of the second motor 840 is connected to the second crank 812, and the second crank 812 and the fourth crank 814 are connected by a connecting rod 820. In this way, the first crank 811 is driven by the first motor 830. Since the first crank 811 and the third crank 813 are connected by a connecting rod 820, the third crank 813 is driven to rotate by the first crank 811. The second crank 812 is driven by the second motor 840. Since the second crank 812 and the fourth crank 814 are connected by a connecting rod 820, the fourth crank 814 is driven to rotate by the second crank 812. When the baffle 700 is in the first position, the third crank 813 is driven to rotate by the first motor 830, so that the deflector 720 connected to the third crank 813 rotates to close the second air outlet 600. The fourth crank 814 is driven to rotate by the second motor 840, so that the deflector 720 connected to the fourth crank 814 rotates to guide the airflow flowing through the first air outlet 500. When the baffle 700 is in the second position, the third crank 813 is driven to rotate by the first motor 830, and the fourth crank 814 is driven to rotate by the second motor 840, so that the deflector 720 connected to the third crank 813 and the deflector 720 connected to the fourth crank 814 both rotate to close the first air outlet 500 and open the second air outlet 600, facilitating the discharge of the adsorbed and treated airflow to the indoor through the first air outlet 500, guiding the airflow while discharging the airflow to the indoor, and discharging the carbon dioxide released by the adsorption module 300 to the outdoor through the second air outlet 600, effectively removing the carbon dioxide in the indoor air.

[0059] Combined with Figure 7-8As shown, in some alternative embodiments, the heating device 400 is disposed on the windward side of the adsorption module 300. In this way, the air flow first passes through the heating device 400 and then through the adsorption module 300, and the heated air flow can be used to more fully heat the adsorption module 300, enabling the carbon dioxide adsorbed on the adsorption module 300 to be released more comprehensively, thereby improving the release efficiency of carbon dioxide.

[0060] Optionally, the heating device 400 is disposed at the center of the windward surface of the adsorption module 300. In this way, the heating device 400 has a wider radiation range on the adsorption module 300, heating the adsorption module 300 more evenly, improving the heating efficiency of the heating device 400, enabling the carbon dioxide adsorbed on the adsorption module 300 to be released more comprehensively, facilitating the discharge of the carbon dioxide released from the adsorption module 300 to the outside, effectively removing carbon dioxide in the indoor air, and improving the user experience.

[0061] Optionally, an installation groove 310 is provided at the center of the adsorption module 300, and the heating device 400 is disposed in the installation groove 310. In this way, the installed heating device 400 has strong stability and is not easily detached when subjected to air flow impact for a long time.

[0062] Optionally, the heating device 400 is an electric heating plate. In this way, the electric heating plate has good heating effect, is easy to obtain, and has low cost.

[0063] Optionally, air grooves 410 diverging from the center of the adsorption module 300 to the edge are provided on the heating device 400. In this way, the air grooves 410 can guide the air flow passing through the heating device 400, causing the air flow to diverge from the center of the adsorption module 300 to the edge. The heat around the heating device 400 diffuses along with the air flow from the center of the adsorption module 300 to the edge, fully heating the adsorption module 300, enabling the carbon dioxide adsorbed on the adsorption module 300 to be released more comprehensively, facilitating the discharge of the carbon dioxide released from the adsorption module 300 to the outside, and effectively removing carbon dioxide in the indoor air.

[0064] Optionally, the air grooves 410 diverge from the center of the heating device 400 to the edge. In this way, the air flow passing through the heating device 400 collides with the heating device 400 and then diverges from its center to the edge, taking away the heat around the heating device 400, and then causing the heat of the heating device 400 to diffuse onto the adsorption module 300, fully heating the adsorption module 300, enabling the carbon dioxide adsorbed on the adsorption module 300 to be released more comprehensively, and facilitating the discharge of the carbon dioxide released from the adsorption module 300 to the outside.

[0065] Optionally, the air groove 410 protrudes from the edge of the heating device 400 in the direction of its divergence. In this way, the air flow in the air groove 410 can be ejected farther when leaving the air groove 410, thereby increasing the radiation range of the air flow and fully heating the adsorption module 300.

[0066] Optionally, the length of the air groove 410 protruding from the edge of the heating device 400 is 1-2 cm. In this way, while increasing the radiation range of the air flow ejected from the air groove 410, it can also reduce the resistance of the air groove 410 protruding from the edge of the heating device 400 to the air flow, better heat the adsorption module 300, and enable the carbon dioxide adsorbed on the adsorption module 300 to be released more comprehensively.

[0067] Optionally, a wind collecting groove 420 is provided at the center of the heating device 400. The air groove 410 is communicated with the wind collecting groove 420, and the air groove 410 diverges from the edge of the wind collecting groove 420 to the edge of the heating device 400. In this way, the air flow flowing through the heating device 400 can be concentrated in the wind collecting groove 420, and then diverge to the surroundings through the air groove 410 communicated with the wind collecting groove 420, improving the flow rate of the diverging air flow, increasing the radiation range of the diverging air flow, fully heating the adsorption module 300, enabling the carbon dioxide adsorbed on the adsorption module 300 to be released more comprehensively, and facilitating the discharge of the carbon dioxide released by the adsorption module 300 to the outside.

[0068] Optionally, a plurality of air grooves 410 are provided and diverge uniformly from the center to the edge of the heating device 400. In this way, the air flow diverging from the air groove 410 can diverge in multiple directions, enabling the diverging air flow to cover the adsorption module 300 more comprehensively, fully heating the adsorption module 300, and enabling the carbon dioxide adsorbed on the adsorption module 300 to be released more comprehensively.

[0069] Optionally, the wind collecting groove 420 is a circular groove. In this way, the air flow blowing towards the wind collecting groove 420 gathers in the wind collecting groove 420, and the air flow generates a pressure that diverges towards the periphery of the wind collecting groove 420, improving the flow rate of the diverging air flow, increasing the radiation range of the diverging air flow, fully heating the adsorption module 300, and enabling the carbon dioxide adsorbed on the adsorption module 300 to be released more comprehensively.

[0070] Optionally, both the air groove 410 and the wind collecting groove 420 are provided on the windward surface of the heating device 400.
