For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0063] As described in the background art, the prior art usually uses an independent air purification device to filter and adsorb carbon dioxide and fine particles in the air to improve air quality. However, the purification efficiency of the existing air purification devices is low, and the filters or adsorbers need to be cleaned and replaced regularly, and cannot operate during maintenance. There are also problems of high maintenance costs and short service life.

[0064] Based on this, please refer to Figures 1 - 10 , embodiments of the present utility model provide an air purification device 100 and an air-conditioning device, which can effectively improve the above-mentioned technical problems, that is, it can improve the purification efficiency, reduce the maintenance cost, and extend the service life. The air purification device 100 and the air-conditioning device will be described in detail below.

[0065] This embodiment provides an air conditioning device, which includes an air conditioning body and an air purification device 100. The air purification device 100 is disposed inside the air conditioning body, and the air purification device 100 can purify the indoor air introduced from the return air outlet of the air conditioning body, thereby improving the indoor air quality and realizing the delivery of healthier air indoors.

[0066] Specifically, please refer to Figures 1 - 4 , Figure 1 which is a schematic structural diagram of the air purification device 100 provided in this embodiment, Figure 2 which is an exploded view of the air purification device 100 provided in this embodiment, Figure 3 which is a schematic diagram of the air purification device 100 provided in this embodiment in the first working state, Figure 4 which is a schematic diagram of the air purification device 100 provided in this embodiment in the second working state. Combining Figures 1 - 4 , the air purification device 100 includes a box body 10, a first adsorption assembly 30, a second adsorption assembly 40, a partition assembly 50, a first desorption assembly 60, and a driving device 70. The box body 10 has an air inlet 11, a purified air outlet 12, and an exhaust air outlet 13. Both the first adsorption assembly 30 and the second adsorption assembly 40 are movably disposed inside the box body 10. The partition assembly 50 is disposed inside the box body 10 and is used to cooperate with the first adsorption assembly 30 and the second adsorption assembly 40 to divide the internal space of the box body 10 into an adsorption chamber 21 and a desorption chamber 22. Among them, the air inlet 11, the adsorption chamber 21, and the purified air outlet 12 are sequentially communicated, and the air inlet 11, the desorption chamber 22, and the exhaust air outlet 13 are sequentially communicated. The first desorption assembly 60 is fixedly disposed inside the box body 10 and is used to desorb the first adsorption assembly 30 or the second adsorption assembly 40 in the desorption chamber 22. The driving device 70 is disposed on the box body 10 and is used to drive both the first adsorption assembly 30 and the second adsorption assembly 40 simultaneously, so that when the first adsorption assembly 30 is in the adsorption chamber 21, the second adsorption assembly 40 is in the desorption chamber 22; or when the first adsorption assembly 30 is in the desorption chamber 22, the second adsorption assembly 40 is in the adsorption chamber 21.

[0067] It should be noted that both the first adsorption component 30 and the second adsorption component 40 have adsorbents, which can adsorb harmful gases such as carbon dioxide in the air to achieve the purpose of purifying the air. Moreover, under the drive of the drive device 70, both the first adsorption component 30 and the second adsorption component 40 have an adsorption station and a desorption station. Among them, the adsorption station can be understood as the working position of the first adsorption component 30 or the second adsorption component 40 in the adsorption chamber 21, at this time, it is used to purify the air in the adsorption chamber 21; while the desorption station can be understood as the working position of the first adsorption component 30 or the second adsorption component 40 in the desorption chamber 22, at this time, the first desorption component 60 desorbs the harmful gases such as carbon dioxide adsorbed by the first adsorption component 30 or the second adsorption component 40, so as to continue to adsorb and purify the harmful gases when in the adsorption station subsequently.

[0068] Please refer to Figure 3 and Figure 4 , it should also be noted that the first working state mentioned above can be understood as: the working state when the drive device 70 drives the first adsorption component 30 to the adsorption station and the second adsorption component 40 to the desorption station at the same time; while the second working state can be understood as: the working state when the drive device 70 drives the first adsorption component 30 to the desorption station and the second adsorption component 40 to the adsorption station at the same time.

[0069] That is to say, the drive device 70 can drive the first adsorption component 30 and the second adsorption component 40 to be in the adsorption chamber 21 or the desorption chamber 22 to achieve alternative air purification: when the first adsorption component 30 is in the adsorption chamber 21, the second adsorption component 40 is in the desorption chamber 22. At this time, the first adsorption component 30 adsorbs and purifies harmful gases such as carbon dioxide in the air entering the adsorption chamber 21 from the air inlet 11 and discharges them from the purified air outlet 12; while the first desorption component 60 desorbs the harmful gases such as carbon dioxide adsorbed by the second adsorption component 40 and discharges the harmful gases from the waste gas outlet 13. Similarly, when the first adsorption component 30 is in the desorption chamber 22, the second adsorption component 40 is in the adsorption chamber 21. At this time, the second adsorption component 40 purifies the air, and the first desorption component 60 desorbs the harmful gases adsorbed by the first adsorption component 30. Therefore, the air purification device 100 can achieve continuous air purification, thereby improving the purification efficiency; moreover, the adsorbents in the first adsorption component 30 and the second adsorption component 40 can be recycled, thereby reducing the maintenance cost and extending the service life of the device.

[0070] Please refer to Figure 1 and Figure 2, in this embodiment, the box body 10 includes a bottom plate 14 and a first side plate 15, a second side plate 16, a third side plate 17, and a fourth side plate 18 that are simultaneously connected to the bottom plate 14.

In this embodiment, the air inlet 11 is provided on the bottom plate 14, and the exhaust gas outlet 13 is provided on the side of the third side plate 17 away from the bottom plate 14, that is, near the purification air outlet 12. Of course, in other embodiments, the exhaust gas outlet 13 can also be provided on the first side plate 15 or the second side plate 16 or the fourth side plate 18. Of course, if the box body 10 has a top plate, the exhaust gas outlet 13 can also be provided on the top plate and separated from the purification air outlet 12 through the separation component 50.

[0072] It should be further noted that the bottom plate 14, the first side plate 15, the second side plate 16, the third side plate 17, and the fourth side plate 18 can be bent and extended, and connected and fixed by screwing or riveting.

[0074] It should be noted that the guiding plate 19 can be a separate sheet metal part, fixed on the third side plate 17 by welding, screwing or riveting, or the guiding plate 19 can also be integrally formed with the third side plate 17. In addition, in some other embodiments, the guiding plate 19 can also not be selected, and the exhaust gas outlet 13 can be connected through a pipeline or directly communicated with the exhaust gas treatment device to facilitate the treatment of the exhaust gas.

[0075] Furthermore, in order to increase the gas pressure at the air inlet 11, better drive the gas flow, and further improve the purification efficiency, in this embodiment, the air purification device 100 further includes a fan 91. The fan 91 is provided at the air inlet 11. It can be understood that the main noise source of the air purification device 100 provided in this embodiment is only the fan 91, and the overall device has low operating noise and low energy consumption.

[0077] Please continue to refer to Figure 1 and Figure 2 , the driving device 70 includes a driver 71 and a switching mechanism 72.

The switching mechanism 72 is simultaneously disposed in the adsorption chamber 21 and the desorption chamber 22, and the first adsorption assembly 30 and the second adsorption assembly 40 are both movably connected to the switching mechanism 72. That is to say, the driver 71 drives the switching mechanism 72 to move, so that the switching mechanism 72 can drive the first adsorption assembly 30 and the second adsorption assembly 40 to alternately switch between the adsorption station and the desorption station.

[0078] Specifically, please refer to Figure 5 , Figure 5 is an exploded view of the switching mechanism 72 provided in this embodiment. Referring to Figures 2 - 5 , the switching mechanism 72 includes a first mounting plate 721, a second mounting plate 722, a first turntable 723, a second turntable 724, and a rotating shaft 725. The first mounting plate 721 and the second mounting plate 722 are spaced apart and are both located in the adsorption chamber 21 and the desorption chamber 22 at the same time. The first turntable 723 is rotatably disposed on the first mounting plate 721, and the second turntable 724 is rotatably disposed on the second mounting plate 722. The first adsorption assembly 30 and the second adsorption assembly 40 are both located between the first mounting plate 721 and the second mounting plate 722, and both ends of the first adsorption assembly 30 are respectively connected to the first turntable 723 and the second turntable 724, and both ends of the second adsorption assembly 40 are respectively connected to the first turntable 723 and the second turntable 724. The rotating shaft 725 passes through the second turntable 724, the second mounting plate 722, the first mounting plate 721, and the first turntable 723 at the same time and is in transmission connection with the driver 71.

[0079] Specifically in this embodiment, the first desorption assembly 60 is located between the first mounting plate 721 and the second mounting plate 722 and is fixedly connected to both the first mounting plate 721 and the second mounting plate 722 at the same time.

[0080] The driver 71 drives the rotating shaft 725 to rotate, thereby driving the first turntable 723 and the second turntable 724 to rotate on the first mounting plate 721 and the second mounting plate 722 respectively, and further driving the rotation and switching of the first adsorption assembly 30 and the second adsorption assembly 40 that are simultaneously disposed on the first turntable 723 and the second turntable 724.

[0081] It should be noted that in this embodiment, the spacing direction between the first mounting plate 721 and the second mounting plate 722 is the same as the spacing direction between the second side plate 16 and the fourth side plate 18; and the first mounting plate 721 is simultaneously fixed to the inner walls of the first side plate 15, the second side plate 16, and the third side plate 17, and the second mounting plate 722 is simultaneously fixed to the inner walls of the second side plate 16, the third side plate 17, and the fourth side plate 18. Of course, in other embodiments, the spacing direction between the first mounting plate 721 and the second mounting plate 722 may also be the same as the spacing direction between the first side plate 15 and the third side plate 17.

[0082] To ensure the rotational stability of the first turntable 723 and the second turntable 724 and prevent interference with other components in the device, in this embodiment, the first turntable 723 is located on the side of the first mounting plate 721 away from the second mounting plate 722, that is, between the first mounting plate 721 and the second side plate 16; the second turntable 724 is located on the side of the second mounting plate 722 away from the first mounting plate 721, that is, between the second mounting plate 722 and the fourth side plate 18.

[0083] Please continue to refer to Figures 2 - 5 Furthermore, the first turntable 723 is provided with a first limiting member 7231 and a second limiting member 7232, the first mounting plate 721 is provided with a first arc-shaped slide rail 7211 and a second arc-shaped slide rail 7212, the first limiting member 7231 is slidably disposed in the first arc-shaped slide rail 7211, and the second limiting member 7232 is slidably disposed in the second arc-shaped slide rail 7212; the second turntable 724 is provided with a third limiting member 7241 and a fourth limiting member 7242, the second mounting plate 722 is provided with a third arc-shaped slide rail 7221 and a fourth arc-shaped slide rail 7222, the third limiting member 7241 is slidably disposed in the third arc-shaped slide rail 7221, and the fourth limiting member 7242 is slidably disposed in the fourth arc-shaped slide rail 7222; wherein, both ends of the first adsorption assembly 30 are respectively connected to the first limiting member 7231 and the third limiting member 7241, and both ends of the second adsorption assembly 40 are respectively connected to the second limiting member 7232 and the fourth limiting member 7242.

[0084] It is easy to understand that the rotating shaft 725 is driven to rotate by the driver 71, and the rotating shaft 725 drives the first turntable 723 and the second turntable 724 to rotate. Specifically, the first limit member 7231 and the third limit member 7241 are respectively connected to the two ends of the first adsorption component 30, and can slide on the first arc-shaped slide rail 7211 and the third arc-shaped slide rail 7221 respectively, thereby realizing the back-and-forth switching of the first adsorption component 30 between the adsorption station and the desorption station; at the same time, the second limit member 7232 and the fourth limit member 7242 are respectively connected to the two ends of the second adsorption component 40, and can slide on the second arc-shaped slide rail 7212 and the fourth arc-shaped slide rail 7222 respectively, thereby realizing the back-and-forth switching of the second adsorption component 40 between the adsorption station and the desorption station.

[0085] In order to ensure the smoothness of the sliding of the first limit member 7231, the second limit member 7232, the third limit member 7241 and the fourth limit member 7242 on their respective slide rails, so that the alternating switching positions of the first adsorption component 30 and the second adsorption component 40 are accurate, in this embodiment, the center of the first arc-shaped slide rail 7211, the center of the second arc-shaped slide rail 7212, and the rotation center point of the first turntable 723 are all on the central axis of the rotating shaft 725; the center of the third arc-shaped slide rail 7221, the center of the fourth arc-shaped slide rail 7222, and the rotation center point of the second turntable 724 are all on the central axis of the rotating shaft 725.

[0086] It should be noted that, in the present embodiment, the driver 71 is specifically a damper actuator; of course, in other embodiments, the driver 71 may also be a servo motor or a motor or other device that can drive the rotating shaft 725 to rotate.

[0087] Combination Figure 5 In order to better realize the synchronous rotation of the turntable and the rotating shaft 725, in the present embodiment, the switching mechanism 72 further includes a first bearing seat 726 and a second bearing seat (not shown in the figure), the first bearing seat 726 is arranged on the first turntable 723, and the second bearing seat is arranged on the second turntable 724. The rotating shaft 725 is simultaneously passed through the center holes of the first turntable 723 and the second turntable 724, and is connected to the inner rings of the first bearing seat 726 and the second bearing seat. The turntable and the rotating shaft 725 are supported by the two bearing seats to maintain the rotation of the overall structure.

[0088] In order to protect the rotating shaft 725 and the bearings and reduce wear and noise, the switching mechanism 72 further includes a shaft sleeve 728 , which is disposed at the connection between the rotating shaft 725 and the driver 71 .

[0089] Further, in order to improve the overall switching operation stability of the switching mechanism 72 and ensure the smooth operation of the first adsorption assembly 30 and the second adsorption assembly 40, in this embodiment, the first limiting member 7231 and the second limiting member 7232 are symmetrically arranged with respect to the third limiting member 7241 and the fourth limiting member 7242 about a central plane perpendicular to the axis of the rotating shaft 725.

[0090] Of course, in this embodiment, the first limiting member 7231 and the second limiting member 7232 are centrally symmetrically arranged about the center point of the first turntable 723; the third limiting member 7241 and the fourth limiting member 7242 are centrally symmetrically arranged about the center point of the second turntable 724. Correspondingly, the center of the first arc-shaped slide rail 7211 coincides with the center of the second arc-shaped slide rail 7212, and the first arc-shaped slide rail 7211 and the second arc-shaped slide rail 7212 are centrally symmetrically arranged about this center; the center of the third arc-shaped slide rail 7221 coincides with the center of the fourth arc-shaped slide rail 7222, and the third arc-shaped slide rail 7221 and the fourth arc-shaped slide rail 7222 are centrally symmetrically arranged about this center. In this way, the operation stability of the first adsorption assembly 30 and the second adsorption assembly 40 is further improved.

[0091] Please refer to Figure 6 , Figure 6 which is a schematic internal structure diagram of the air purification device 100 provided in this embodiment. Combining Figure 2 , Figure 3 , Figure 4 and Figure 6 , the separation assembly 50 includes a first separation plate 51, a second separation plate 52 and a mounting frame 53. The mounting frame 53 is fixed inside the box body 10. Specifically, in this embodiment, the mounting frame 53 is simultaneously fixed on the first mounting plate 721 and the second mounting plate 722; the first separation plate 51 and the second separation plate 52 are respectively arranged on opposite sides of the mounting frame 53, and the second separation plate 52 is connected to the mounting frame 53; the first adsorption assembly 30 is located between the first separation plate 51 and the mounting frame 53, the second adsorption assembly 40 is located on the side of the second separation plate 52 away from the mounting frame 53, and the first desorption assembly 60 is located on the side of the second adsorption assembly 40 away from the second separation plate 52; wherein, the first separation plate 51 is used to cooperate with the first adsorption assembly 30, and the second separation plate 52 is used to cooperate with the second adsorption assembly 40.

[0092] As Figure 3 and Figure 4As shown, it should be noted that in this embodiment, the first desorption component 60 is specifically arranged on the side of the second adsorption component 40 away from the second partition plate 52, which can also be understood as between the second adsorption component 40 and the blower 91. In this way, when the first adsorption component 30 is in the desorption station and the second adsorption component 40 is in the adsorption station, the distance between the first adsorption component 30 and the first desorption component 60 is relatively far. To further improve the desorption effect of the first adsorption component 30 in the desorption station, further, the air purification device 100 further includes a second desorption component 80. The second desorption component 80 is arranged between the mounting bracket 53 and the second adsorption component 40 and is connected to the mounting bracket 53. The second desorption component 80 is located in the desorption chamber 22.

[0093] It is easy to understand that when the first adsorption component 30 is in the desorption station, only the second desorption component 80 closer to it can be started for desorption work, or only the first desorption component 60 can be started; of course, the first desorption component 60 and the second desorption component 80 can also work simultaneously, which can further improve the desorption efficiency.

[0094] It should be noted that the adsorption-desorption method is not limited. It can be temperature swing adsorption (TSA method), pressure swing adsorption (PSA method), moisture swing adsorption (MSA method), vacuum adsorption (VSA method), photo-responsive adsorption, etc., or a combination of the above technologies, such as: pressure swing-temperature swing adsorption (PTSA method), temperature swing-vacuum adsorption (TVSA method), etc. Correspondingly, the first desorption component 60 can be one or more of a PTC heater, a radiation heater, a pulse blowing valve, and an ultraviolet generator; the second desorption component 80 can also be one or more of a PTC heater, a radiation heater, a pulse blowing valve, and an ultraviolet generator.

[0095] For example, specifically in this embodiment, both the first desorption component 60 and the second desorption component 80 are PTC heaters. In this way, the corresponding adsorption-desorption method is the temperature swing adsorption method, that is, low-temperature adsorption and temperature-raising desorption; specifically, air enters from the air inlet 11, and the air is introduced into the desorption chamber 22 by the action of the blower 91. The first desorption component 60 or the second desorption component 80 heats the air and flows through the first adsorption component 30 or the second adsorption component 40, so that harmful gases such as carbon dioxide adsorbed by the adsorbent are desorbed and then discharged from the waste gas outlet 13.

[0096] In addition, it should also be noted that the number of the first desorption component 60 and the second desorption component 80 is not limited either. Both can be one or more, and the specific number needs to be determined according to the design requirements of the purification device and the actual purification environment.

[0097] Please refer to Figure 7 , Figure 7Exploded view of the first adsorption component 30 and the second adsorption component 40 provided in this embodiment, in combination with Figure 3 , Figure 4 , Figure 6 and Figure 7 , specifically, the first adsorption component 30 includes a first adsorption box 31 and a first base 32. The first adsorption box 31 is disposed on the first base 32. Opposite sides of the first base 32 extend toward the first partition plate 51 to form a first extension portion 321 and a second extension portion 322. One end of the first partition plate 51 is disposed between the first extension portion 321 and the second extension portion 322. The second adsorption component 40 includes a second adsorption box 41 and a second base 42. The second adsorption box 41 is disposed on the second base 42. Opposite sides of the second base 42 extend toward the second partition plate 52 to form a third extension portion 421 and a fourth extension portion 422. One end of the second partition plate 52 is disposed between the third extension portion 421 and the fourth extension portion 422.

[0098] That is to say, in this embodiment, through the cooperation between the first extension portion 321 and the second extension portion 322 and the first partition plate 51, no matter whether the first adsorption component 30 is driven to switch to the desorption station or the adsorption station, it can cooperate with the first partition plate 51 to achieve the separation of the internal space of the box body 10 and avoid the air cross-flow between the adsorption chamber 21 and the desorption chamber 22. Similarly, through the cooperation between the third extension portion 421 and the fourth extension portion 422 and the second partition plate 52, no matter whether the second adsorption component 40 is driven to switch to the desorption station or the adsorption station, it can cooperate with the second partition plate 52 and can also achieve the separation of the internal space of the box body 10 and avoid the air cross-flow between the adsorption chamber 21 and the desorption chamber 22.

[0099] It should be noted that the bottoms of the first base 32 and the second base 42 are both hollow box structures. By placing the first adsorption box 31 and the second adsorption box 41 at the hollow structure, air can flow through the first adsorption box 31 and the second adsorption box 41, and harmful gases such as carbon dioxide in the air are adsorbed by the adsorbent in the adsorption box to achieve the purification effect.

[0100] In order to further ensure the sealing effect, sealing strips (not shown in the figure) are also provided at the joints between the first adsorption box 31 and the first base 32 and at the joints between the second adsorption box 41 and the second base 42. The joints include the four sides and the bottom of the adsorption box. By providing the sealing strips, gas leakage from the joints can be effectively prevented, and the air purification effect can be further improved.

[0101] Specifically, please refer to Figure 8 , Figure 8 Exploded view of the first adsorption box 31 and the second adsorption box 41 provided in this embodiment, in combination withFigure 8 , the first adsorption box 31 includes a first box body 311, a first upper cover plate 312, a first lower cover plate 313, a first screen 314 and a second screen 315. The first upper cover plate 312 and the first lower cover plate 313 are respectively connected to both sides of the first box body 311, and the first lower cover plate 313 is arranged on the first base 32; the first screen 314 is arranged between the first upper cover plate 312 and the first box body 311, and the second screen 315 is arranged between the first lower cover plate 313 and the first box body 311; the second adsorption box 41 includes a second box body 411, a second upper cover plate 412, a second lower cover plate 413, a third screen 414 and a fourth screen 415. The second upper cover plate 412 and the second lower cover plate 413 are respectively connected to both sides of the second box body 411, and the second lower cover plate 413 is arranged on the second base 42; the third screen 414 is arranged between the second upper cover plate 412 and the second box body 411, and the fourth screen 415 is arranged between the second lower cover plate 413 and the second box body 411; wherein, the first screen 314, the second screen 315, the third screen 414 and the fourth screen 415 are all loaded with adsorbents.

[0102] It should be noted that the first upper cover plate 312, the first lower cover plate 313, the second upper cover plate 412 and the second lower cover plate 413 are all of a hollow structure, which can facilitate gas circulation and is used for the overall structure support; the upper and lower ends of the first box body 311 and the second box body 411 are both bent inward to form a plurality of connection holes for connecting with the upper and lower cover plates; the screen is arranged between the upper and lower cover plates and the box body, which can prevent the loaded adsorbent from leaking out.

[0103] In addition, it should also be noted that the type and state of the adsorbent in this embodiment are not limited, and it can be a physical adsorbent (porous adsorption material, such as: activated carbon, zeolite, silica gel, MOF material, etc.), a chemical adsorbent (such as: alkanolamines, organic amines, potassium carbonate aqueous solution, ammonia water, ionic liquid, etc.) or a membrane adsorbent (such as: gas separation membrane, gas absorption membrane, etc.), and any adsorbent that can play a role in gas separation can be used.

[0104] Of course, the aforementioned first adsorption box 31 and the second adsorption box 41 are only used as containers for loading the adsorbent, and the specific box body structure can be adaptively modified according to the state of the adsorbent.

[0105] Please refer to Figure 9 , Figure 9 which is a schematic structural diagram of the first partition plate 51 provided in this embodiment. Combining Figure 3 , Figure 4 , Figure 7 and Figure 9, specifically in this embodiment, the first partition plate 51 includes an inclined portion 511 and a first vertical portion 512. The inclined portion 511 is disposed near the waste gas outlet 13 and is connected to the first vertical portion 512. The first vertical portion 512 extends into the space between the first extension portion 321 and the second extension portion 322.

[0106] By providing the inclined portion 511, the output channel of the purified air can be enlarged, and the flow rate of the purified air can be further increased. Through the cooperation of the first vertical portion 512 with the first extension portion 321 and the second extension portion 322, the movement of the first base 32 can be restricted, which not only plays a certain protective role but also realizes the separation between the adsorption chamber 21 and the desorption chamber 22. Of course, in other embodiments, the first partition plate 51 can also be a single-piece vertical plate as long as it can separate the purified air from the waste gas.

[0107] Please refer to Figure 10 , Figure 10 is a schematic structural diagram of the second partition plate 52 provided in this embodiment. Combining Figure 3 , Figure 4 , Figure 7 and Figure 10 , specifically in this embodiment, the second partition plate 52 includes a second vertical portion 521, a horizontal portion 522, and a third vertical portion 523. The second vertical portion 521, the horizontal portion 522, and the third vertical portion 523 are connected in sequence. The second vertical portion 521 is connected to the mounting bracket 53, and the third vertical portion 523 extends into the space between the third extension portion 421 and the fourth extension portion 422.

[0108] It is easy to understand that by connecting the second vertical portion 521 to the mounting bracket 53, the overall structure of the second partition plate 52 can be installed and fixed. By cooperating the third vertical portion 523 with the third extension portion 421 and the fourth extension portion 422 to restrict the movement of the second base 42, it also plays a certain protective role while realizing the separation between the adsorption chamber 21 and the desorption chamber 22.

[0109] Furthermore, combining Figure 6 and Figure 10 , the rotating shaft 725 is located above the horizontal portion 522, and the installation space formed by the second vertical portion 521 and the horizontal portion 522 provides a protective effect for the rotation of the rotating shaft 725.

[0110] In addition, in some embodiments, the air purification device 100 may further include a plurality of sensors for monitoring the gas states at the air inlet 11, the waste gas outlet 13, the purified air outlet 12, and inside the purification device. The plurality of sensors may include: temperature sensors, humidity sensors, particle sensors, optical sensors, pressure sensors, wind speed sensors, and TVOC sensors, etc.

[0111] In summary, the embodiments of the present utility model provide an air purification device 100 and an air conditioning device. The air purification device 100 includes a box body 10, a first adsorption component 30, a second adsorption component 40, a partition component 50, a first desorption component 60, and a driving device 70. The box body 10 has an air inlet 11, a purified air outlet 12, and an exhaust air outlet 13. The first adsorption component 30 and the second adsorption component 40 are both movably arranged in the box body 10. The partition component 50 is arranged in the box body 10 and is used to cooperate with the first adsorption component 30 and the second adsorption component 40 to divide the internal space of the box body 10 into an adsorption chamber 21 and a desorption chamber 22. Among them, the air inlet 11, the adsorption chamber 21, and the purified air outlet 12 are connected in sequence, and the air inlet 11, the desorption chamber 22, and the exhaust air outlet 13 are connected in sequence. The first desorption component 60 is fixedly arranged in the box body 10 and is used to desorb the first adsorption component 30 or the second adsorption component 40 in the desorption station. The driving device 70 is arranged in the box body 10 and is used to drive the first adsorption component 30 and the second adsorption component 40 simultaneously, so that when the first adsorption component 30 is in the adsorption chamber 21, the second adsorption component 40 is in the desorption chamber 22; or when the first adsorption component 30 is in the desorption chamber 22, the second adsorption component 40 is in the adsorption chamber 21.

[0112] That is to say, the driving device 70 can switch the first adsorption component 30 and the second adsorption component 40 to be in the adsorption chamber 21 or the desorption chamber 22, realizing the alternate purification of air: when the first adsorption component 30 is in the adsorption chamber 21, the second adsorption component 40 is in the desorption chamber 22. At this time, the first adsorption component 30 adsorbs and purifies harmful gases such as carbon dioxide in the air entering the adsorption chamber 21 from the air inlet 11 and discharges them from the purified air outlet 12. And the first desorption component 60 desorbs the harmful gases such as carbon dioxide adsorbed by the second adsorption component 40 and discharges the harmful gases from the exhaust air outlet 13. Similarly, when the first adsorption component 30 is in the desorption chamber 22, the second adsorption component 40 is in the adsorption chamber 21. At this time, it is the second adsorption component 40 that purifies the air, and the first desorption component 60 desorbs the harmful gases adsorbed by the first adsorption component 30.

[0113] Therefore, the air purification device 100 can realize continuous air purification, thereby improving the purification efficiency. And the adsorbents in the first adsorption component 30 and the second adsorption component 40 can be recycled, thereby reducing the maintenance cost and prolonging the service life of the device.

[0114] The air conditioning device includes the air purification device 100, which has all the functions and beneficial effects of the air purification device 100.

[0115] The above are only specific embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
