Description

Technical Field

[0001] This application belongs to the field of electrical technology, specifically relating to an odor removal device, an air purifier, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] In related technologies, people are paying more and more attention to the air quality of their living environment, so air purification devices are being used more and more frequently. In order to remove HCHO (formaldehyde) and VOC (volatile organic compounds) from the air, the existing treatment methods generally use adsorption materials such as activated carbon and molecular sieves for adsorption. However, the adsorption capacity of adsorption materials is limited, and they are prone to adsorption saturation, which leads to poor adsorption function and short-term maintenance of filtration performance.

[0003] In order to regenerate the adsorbent material, fresh air needs to be introduced into the air conditioner for desorption, which increases the complexity of the system. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an odor removal device, an air purifier, an indoor air conditioning unit, and an air conditioner, aiming to at least partially solve the technical problem that introducing fresh air into the air conditioner for desorption in order to regenerate the adsorbent material increases the complexity of the system.

[0005] The technical solution of this invention is as follows:

[0006] An odor removal device is characterized by comprising: a housing having a purification duct having an air inlet and an air outlet; an adsorption element rotatably disposed within the purification duct; and a plasma assembly fixedly disposed within the purification duct, wherein a portion of the end face of the adsorption element is opposite to the plasma assembly in the direction of rotation axis.

[0007] The housing of this application has a purification duct with an air inlet and an air outlet. Indoor air enters the purification duct through the air inlet. Since the adsorbent is rotatably mounted within the purification duct, when indoor air passes through it, the adsorbent adsorbs odor pollutants, achieving online adsorption. The purified air is then discharged through the air outlet. Simultaneously, the rotation of the adsorbent within the purification duct allows indoor air to swirl around it, ensuring sufficient contact between the air and the adsorbent and guaranteeing the adsorption effect. Because the plasma assembly is fixed within the purification duct, with a portion of its end face opposite that of the adsorbent, activation... The plasma module generates plasma wind, which carries high-energy electrons and strong oxidizing groups that act on the area opposite the adsorbent and the plasma module. This purifies and decomposes the odor pollutants adsorbed in that area of ​​the adsorbent into harmless gases such as CO2 and H2O, thus desorbing the adsorbent and regenerating its adsorption capacity. The purified air is then discharged into the room through the air outlet of the purification duct, forming an internal circulation that prevents secondary pollution and improves indoor air comfort. The adsorbent does not need to be replaced, reducing costs. The purified air, along with harmless gases such as CO2 and H2O, are discharged into the room through the air outlet of the purification duct, eliminating the need for constructing new ducts and saving space.

[0008] In some implementations, the ratio of the projection of the plasma component on the end face to the area of ​​the end face is 1:2 to 1:5, which can achieve a better purification effect.

[0009] In some embodiments, the odor removal device further includes an ozone decomposition element fixedly disposed within the purification duct. The ozone decomposition element and the plasma assembly are disposed opposite each other on both sides of the adsorption element in the direction of the rotation axis, and the ozone is decomposed by the ozone decomposition element.

[0010] In some implementations, the area ratio of the ozone decomposition element to the plasma assembly is 1:1 to ensure that the ozone generated by the plasma assembly is fully decomposed.

[0011] In some implementations, the distance between the ozone decomposition element and the adsorption element is 1mm-5mm to prevent ozone escape and to control the ozone concentration in trace amounts.

[0012] In some embodiments, the odor removal device further includes a drive assembly connected to the adsorbent to drive the adsorbent to rotate, the drive assembly driving the adsorbent to rotate within the purification duct, the drive assembly being disposed within the purification duct.

[0013] In some implementations, the drive assembly is positioned on a side away from the air inlet and the air outlet to avoid interfering with the airflow.

[0014] In some embodiments, the drive assembly includes a driver and a transmission gear connected to the actuating end of the driver, the transmission gear meshing with the circumferential surface of the adsorption element.

[0015] The actuator drives the adsorption element to rotate within the purification duct via a transmission gear.

[0016] Furthermore, the plasma assembly is fan-shaped to match the diameter of the adsorbent, so that the plasma assembly can cover the adsorbent.

[0017] In some implementations, the ratio of the air inlet velocity to the plasma wind velocity of the plasma assembly is 1:2 to 1:4, ensuring that the high-energy electrons and strong oxidizing groups carried by the plasma wind generated by the plasma assembly can fully act on the area opposite the adsorbent and the plasma assembly.

[0018] In some implementations, the plasma assembly discharges in the form of needle tip discharge or sawtooth discharge.

[0019] Compared to dielectric barrier discharge, needle tip discharge or sawtooth discharge can use ultra-high voltage to disinfect bacteria and viruses in indoor air, ensuring clean indoor air. At the same time, the plasma wind generated can carry sufficient high-energy electrons and strong oxidizing radicals to act on the adsorbent, which can fully purify and decompose the odor pollutants adsorbed by the adsorbent into harmless gases such as CO2 and H2O, so as to fully desorb the adsorbent and regenerate the adsorption capacity of the adsorbent.

[0020] Based on the same inventive concept, the present invention also provides an air purifier, including the aforementioned odor removal device.

[0021] Based on the same inventive concept, the present invention also provides an indoor air conditioning unit, including the air purifier or the odor removal device.

[0022] Based on the same inventive concept, the present invention also provides an air conditioner, including the air purifier, the indoor unit of the air conditioner, or the odor removal device.

[0023] The beneficial effects of the present invention include at least the following:

[0024] In order to regenerate the adsorbent material and ensure its adsorption capacity, the regeneration method requires the introduction of fresh air for desorption. Therefore, a new desorption duct needs to be constructed, which increases the complexity of the system. At the same time, the desorption duct discharges the desorbed gas, causing secondary pollution.

[0025] The housing of this application has a purification duct with an air inlet and an air outlet. Indoor air enters the purification duct through the air inlet. Since the adsorbent is rotatably mounted within the purification duct, when indoor air passes through it, the adsorbent adsorbs odor pollutants, achieving online adsorption. The purified air is then discharged through the air outlet. Simultaneously, the rotation of the adsorbent within the purification duct allows indoor air to swirl around it, ensuring sufficient contact between the air and the adsorbent and guaranteeing the adsorption effect. Because the plasma assembly is located within the purification duct, with a portion of its end face opposite that of the adsorbent, it activates upon startup. The ion module generates plasma wind, which carries high-energy electrons and strong oxidizing groups that act on the area opposite the adsorbent and the plasma module. This purifies and decomposes the odor pollutants adsorbed in that area of ​​the adsorbent into harmless gases such as CO2 and H2O, thus desorbing the adsorbent from that area and regenerating its adsorption capacity. The purified air is then discharged into the room through the air outlet of the purification duct, forming an internal circulation that prevents secondary pollution and improves indoor air comfort. The adsorbent does not need to be replaced, reducing costs. The purified air, along with harmless gases such as CO2 and H2O, are discharged into the room through the air outlet of the purification duct, eliminating the need for new ductwork and saving space.

[0045] This application is described below with reference to the accompanying drawings and specific embodiments:

[0046] The odor removal device, air purifier, indoor air conditioning unit, and air conditioner provided in this embodiment aim to at least partially solve the technical problem that introducing fresh air into the air conditioner for desorption in order to regenerate the adsorbent material increases the complexity of the system.

[0047] Figure 1 This is a schematic diagram of the odor removal device in this embodiment. Figure 2 for Figure 1 Schematic diagram of an odor removal device. (Combined with...) Figure 1 and Figure 2 The odor removal device of this embodiment includes a housing 10, an adsorption element 30, and a plasma assembly 40. The housing 10 has a purification air duct 20, which has an air inlet 201 and an air outlet 202. The adsorption element 30 is rotatably disposed within the purification air duct 20. The plasma assembly 40 is fixedly disposed within the purification air duct 20, and a portion of the plasma assembly 40 is opposite to the end face of the adsorption element 30 in the direction of the rotation axis 50.

[0048] The air inlet 201 and air outlet 202 of the purification air duct 20 are both connected to the room where the air to be purified is located. The odor removal device can be installed inside the space to be purified or outside the space to be purified.

[0049] When indoor air passes through the adsorption element 30, the adsorption element 30 adsorbs odor pollutants in the indoor air.

[0050] The adsorption element 30 is rotatably disposed within the purification air duct 20. There are several ways in which the adsorption element 30 can be rotatably disposed, such as: the adsorption element 30 is sleeved on the rotating shaft 50, the rotating shaft 50 is connected to the housing 10, and the rotating shaft 50 supports the adsorption element 30. In this case, the rotating shaft 50 and the adsorption element 30 are rotatably connected, while the rotating shaft 50 and the housing 10 are fixedly connected; or the rotating shaft 50 and the adsorption element 30 are fixedly connected, while the rotating shaft 50 and the housing 10 are rotatably connected; of course, the rotating shaft 50 and either the adsorption element 30 or the housing 10 can be integrally formed, and the other can be rotatably connected.

[0051] The plasma assembly 40 is located on the side near the air inlet 201.

[0052] The end face of the adsorption element 30 is perpendicular to the rotating shaft 50.

[0053] The adsorption element 30 can rotate clockwise or counterclockwise within the purification duct 20. There is no limitation on this, and it can be set according to specific needs or purification effect.

[0054] In order to regenerate the adsorbent material and ensure its adsorption capacity, the regeneration method requires the introduction of fresh air for desorption. Therefore, a new desorption duct needs to be constructed, which increases the complexity of the system. At the same time, the desorption duct discharges the desorbed gas, causing secondary pollution.

[0055] The housing 10 of this application has a purification air duct 20, which has an air inlet 201 and an air outlet 202. Indoor air enters the purification air duct 20 through the air inlet 201. Since the adsorbent 30 is rotatably disposed within the purification air duct 20, when indoor air passes through the adsorbent 30, the adsorbent 30 adsorbs odor pollutants from the indoor air, achieving online adsorption. The purified air is discharged through the air outlet 202 of the purification air duct 20. Simultaneously, the rotation of the adsorbent 30 within the purification air duct 20 allows the indoor air to swirl around the adsorbent 30, ensuring sufficient contact between the indoor air and the adsorbent 30 and guaranteeing the adsorption effect. Since the plasma assembly 40 is disposed within the purification air duct 20, a portion of the end face of the plasma assembly 40 and the adsorbent 30... Since the regions are relatively opposite, when the plasma component 40 is activated, it generates plasma wind. The high-energy electrons and strong oxidizing groups carried by the plasma wind act on the area opposite the adsorbent 30 and the plasma component 40, purifying and decomposing the odor pollutants adsorbed in that area of ​​the adsorbent 30 into harmless gases such as CO2 and H2O, thereby desorbing the adsorbent 30 in that area and regenerating its adsorption capacity. The pollutants are then discharged into the room through the air outlet 202 of the purification duct 20, forming an internal circulation system that does not produce secondary pollution, improves indoor air comfort, eliminates the need to replace the adsorbent 30, and reduces costs. The purified air, CO2, H2O, and other harmless gases are all discharged into the room through the air outlet 202 of the purification duct 20, eliminating the need to construct a new duct and saving space.

[0056] In some embodiments, a fan is provided inside the purification duct 20. By starting the fan, indoor air enters the purification duct 20 through the air inlet 201 and is discharged from the air outlet 202 after passing through the adsorption element 30.

[0057] Combination Figure 1 In some embodiments, the plasma assembly 40 can be connected to the housing 10, and the housing 10 supports the plasma assembly 40. Of course, the plasma assembly 40 can also be connected to the rotating shaft 50, and the rotating shaft 50 supports the plasma assembly 40.

[0058] In existing technologies, a regeneration temperature field is generally used to desorb the adsorbent 30. However, this method is energy-intensive, has a small regeneration area, and may result in incomplete regeneration of the adsorbent 30 or require secondary regeneration. Therefore, this application uses a plasma assembly 40 to generate plasma wind. The high-energy electrons and strong oxidizing groups carried by the plasma wind act on the area of ​​the adsorbent 30 opposite to the plasma assembly 40, purifying and decomposing the odor pollutants adsorbed in that area of ​​the adsorbent 30 into harmless gases such as CO2 and H2O, thereby desorbing the adsorbent from that area of ​​the adsorbent 30 and regenerating its adsorption capacity. This method has relatively low energy consumption, ensures complete regeneration of the adsorbent 30, does not require heating, and is easily implemented in air conditioners.

[0059] In some embodiments, the voltage of the plasma module 40 is controlled between 7kV and 30kV. The ultra-high voltage exceeding 7kV can eliminate bacteria and viruses in indoor air, ensuring clean indoor air. To ensure that the plasma module 40 can generate ultra-high voltage, and to reduce energy consumption, the voltage of the plasma module 40 is preferably controlled between 10kV and 25kV.

[0060] In this embodiment, since the voltage of the plasma component 40 is between 10kV and 25kV, when the plasma component 40 is working, the air is disturbed and flows under the ultra-high voltage electric field. The flowing air carries a large number of high-energy electrons and strong oxidizing groups, which purify and decompose the pollutants adsorbed by the adsorbent 30 into harmless gases such as CO2 and H2O.

[0061] In some embodiments, the high-energy electrons and strong oxidizing groups carried by the plasma wind act on the first region of the adsorbent 30 opposite to the plasma component 40, purifying and decomposing the odor pollutants adsorbed in the first region of the adsorbent 30 into harmless gases such as CO2 and H2O, thereby desorbing the first region and regenerating the adsorption capacity of the first region of the adsorbent 30. Since the adsorbent 30 is rotatably disposed in the purification air duct 20, when the first region of the adsorbent 30 has finished desorbing, the adsorbent 30 rotates so that the first region of the adsorbent 30 is no longer opposite to the plasma component 40. The first region of the adsorbent 30 adsorbs odor pollutants in the indoor air, which can continuously and efficiently treat odor pollutants in the indoor air. When the adsorbent 30 rotates relative to the plasma assembly 40, and the first region of the adsorbent 30 is no longer opposite to the plasma assembly 40, the second region of the adsorbent 30 becomes opposite to the plasma assembly 40. The plasma wind generated by the plasma assembly 40 desorbs the second region of the adsorbent 30. The plasma assembly 40 can continuously and efficiently purify and decompose the odor pollutants adsorbed in each region of the adsorbent 30, ensuring that the adsorbent 30 can continuously adsorb odor pollutants without needing to replace it, thus reducing costs.

[0062] In this embodiment, in order to save energy, the plasma assembly 40 can be started after the adsorption element 30 has adsorbed for a certain period of time, so that the plasma assembly 40 operates in an intermittent manner.

[0063] Combination Figure 1 and Figure 2 In some embodiments, to achieve better purification results, the ratio of the projection of the plasma component 40 on its end face to the area of ​​the end face is 1:2-1:5. This ensures that the plasma component 40 fully covers a sufficient area of ​​the end face of the adsorbent 30, enabling sufficient desorption of the area covered by the plasma component 40. The area of ​​the adsorbent 30 not covered by the plasma component 40 can then effectively adsorb odor pollutants in the indoor air, ensuring clean indoor air. Preferably, the ratio of the projection of the plasma component 40 on its end face to the area of ​​the end face is 1:4.

[0064] Combination Figure 1 and Figure 2 In some embodiments, since the plasma wind generated by the plasma assembly 40 contains ozone, in order to eliminate ozone and ensure air quality, the odor removal device also includes an ozone decomposition component 60 fixedly disposed within the purification duct 20. The ozone decomposition component 60 and the plasma assembly 40 are disposed opposite each other on both sides of the adsorption component 30 in the direction of the rotation axis 50, and the ozone is decomposed by the ozone decomposition component 60. That is, the plasma assembly 40 is disposed between the adsorption component 30 and the air inlet 201, and the ozone decomposition component 60 is disposed between the adsorption component 30 and the air outlet 202.

[0065] In this embodiment, the plasma component 40 is activated, generating plasma wind. The high-energy electrons and strong oxidizing groups carried by the plasma wind act on the area opposite the adsorbent 30 and the plasma component 40, purifying and decomposing the odor pollutants adsorbed in this area of ​​the adsorbent 30 into harmless gases such as CO2 and H2O. The harmless gases such as ozone, CO2, and H2O will reach the ozone decomposition component 60, which decomposes the ozone, ensuring clean indoor air and avoiding any impact on the health of people in the room.

[0066] Combination Figure 1 and Figure 2 In this embodiment, in order to ensure that the ozone generated by the plasma component 40 is fully decomposed, the area ratio of the ozone decomposition component 60 to the plasma component 40 is 1:1, and the shape of the ozone decomposition component 60 matches the shape of the plasma component 40. This can prevent ozone from escaping, fully decompose the ozone, ensure clean indoor air, and avoid affecting the health of people in the room.

[0067] Combination Figure 1 and Figure 2In this embodiment, if the distance between the ozone decomposition component 60 and the adsorption component 30 is too large, ozone will escape and cause discomfort to the human body. The distance between the ozone decomposition component 60 and the adsorption component 30 is 1mm-5mm. That is, the distance between the ozone decomposition component 60 and the adsorption component 30 in the direction of the rotation shaft 50 is 1mm-5mm. This can control the ozone concentration to be less than or equal to 0.01ppm at the air outlet 202. The trace amount of ozone enters the room with harmless gases such as CO2 and H2O, giving people a fresh feeling like after a thunderstorm, thus improving environmental comfort. Preferably, the distance between the ozone decomposition component 60 and the adsorption component 30 is 3mm.

[0068] Figure 6 for Figure 1 A schematic diagram of the ozone decomposition component in a central odor removal device. (Combined with...) Figure 6 In this embodiment, the ozone decomposition component 60 includes an ozone decomposition mesh 601 coated with an ozone decomposition agent 602. When ozone passes through the ozone decomposition mesh 601, the ozone is decomposed by the ozone decomposition agent 602. In this embodiment, the ozone decomposition mesh 601 can be a stainless steel mesh, an aluminum mesh, or other metal mesh, and the ozone decomposition agent 602 can be one or more manganese-based, iron-based, or cobalt-based catalysts.

[0069] In this embodiment, to ensure the effectiveness of ozone decomposition, the thickness of the ozone decomposition mesh 601 is 3mm-10mm, so as to ensure that the ozone concentration at the air outlet 202 is less than or equal to 0.01ppm. Preferably, the thickness of the ozone decomposition mesh 601 is within 4mm-8mm.

[0070] Combination Figure 1 and Figure 2 In some embodiments, the adsorbent 30 includes a rotating wheel 301 loaded with adsorbent material. When indoor air passes through the rotating wheel 301, the adsorbent material loaded on the rotating wheel 301 adsorbs odor pollutants from the indoor air, achieving online adsorption. The purified air is discharged through the air outlet 202 of the purification duct 20. Simultaneously, the rotating wheel 301 rotates within the purification duct 20, allowing the indoor air to swirl around the rotating wheel 301, ensuring sufficient contact between the indoor air and the rotating wheel 301 and guaranteeing the adsorption effect. While the rotating wheel 301 rotates, the adsorbent material in different areas of the rotating wheel 301 can be positioned opposite the plasma component 40, allowing the high-energy electrons and strong oxidizing groups carried by the plasma wind generated by the plasma component 40 to act on the areas of the adsorbent 30 opposite to the plasma component 40. This purifies and decomposes the odor pollutants adsorbed in that area of ​​the adsorbent 30 into harmless gases such as CO2 and H2O, thereby desorbing the adsorbent from that area of ​​the adsorbent 30 and regenerating the adsorption capacity of that area of ​​the adsorbent 30.

[0071] In this embodiment, the material of the rotating wheel 301 can be one of honeycomb corrugated paper, aluminum honeycomb, or nickel foam, so as to facilitate the loading of adsorption materials and at the same time, facilitate the flow of air.

[0072] In this embodiment, to ensure the adsorption effect of the rotating wheel 301, the thickness of the rotating wheel 301 is 20mm-40mm. However, to reduce costs and avoid making the rotating wheel 301 too heavy, the thickness of the rotating wheel 301 is preferably 20mm.

[0073] In this embodiment, to ensure the adsorption effect of the rotating wheel 301, the diameter of the rotating wheel 301 is 150mm-200mm. To reduce costs and the space occupied by the rotating wheel 301, the thickness of the rotating wheel 301 is preferably 150mm.

[0074] In this embodiment, the adsorbent material can be an adsorbent that easily adsorbs moisture from the air, such as silica gel, molecular sieve, or activated carbon. The adsorbent can adsorb moisture from the indoor air, and the adsorbed moisture, under the action of an ultra-high voltage electric field, helps the plasma wind generate more strong oxidizing groups to achieve deep purification of the adsorbent 30. Furthermore, under the regeneration of the plasma wind, it helps maintain the indoor air humidity.

[0075] Figure 3 for Figure 1 A schematic diagram of the first arrangement of the adsorption components in the odor removal device. Figure 4 for Figure 1 A schematic diagram of the second arrangement of the adsorption element in the odor removal device. (Combined with...) Figure 3 and Figure 4 In this embodiment, depending on the arrangement of the housing 10, the rotating wheel 301 can be arranged horizontally or vertically within the housing 10 to save space.

[0076] Combination Figure 1 In some embodiments, in order to enable the adsorption element 30 to rotate within the purification duct 20, the odor removal device further includes a drive assembly 70 connected to the adsorption element 30 to drive the adsorption element 30 to rotate. The drive assembly 70 drives the adsorption element 30 to rotate within the purification duct 20. The drive assembly 70 is disposed within the purification duct 20.

[0077] In this embodiment, when indoor air passes through the adsorbent 30, the adsorbent material loaded on the adsorbent 30 adsorbs odor pollutants from the indoor air, achieving online adsorption. The purified air is discharged through the air outlet 202 of the purification duct 20. Simultaneously, the drive component 70 drives the adsorbent 30 to rotate within the purification duct 20, allowing the indoor air to swirl around the adsorbent 30, ensuring sufficient contact between the indoor air and the adsorbent 30 and guaranteeing the adsorption effect. While the adsorbent 30 rotates, the adsorbent material in different areas of the adsorbent 30 can be positioned opposite the plasma component 40. This allows the high-energy electrons and strong oxidizing groups carried by the plasma wind generated by the plasma component 40 to act on the areas of the adsorbent 30 opposite to the plasma component 40, purifying and decomposing the odor pollutants adsorbed in that area of ​​the adsorbent 30 into harmless gases such as CO2 and H2O, thereby desorbing the pollutants from that area of ​​the adsorbent 30 and regenerating the adsorption capacity of that area.

[0078] Combination Figure 1 In this embodiment, the drive component 70 is located on the side away from the air inlet 201 and the air outlet 202, so as to avoid the drive component 70 affecting the flow of indoor air to the adsorption component 30, and also to avoid affecting the flow of the adsorbed air to the air outlet 202, thus ensuring smooth airflow.

[0079] Combination Figure 1 In this embodiment, to enable the adsorption element 30 to rotate within the purification duct 20, the drive assembly 70 includes a driver 701 and a transmission gear 702 connected to the actuating end of the driver 701. The transmission gear 702 meshes with the circumferential surface of the adsorption element 30. That is, the circumferential surface of the adsorption element 30 has multiple teeth, making the adsorption element 30 a gear structure, and the transmission gear 702 can mesh with the teeth on the circumferential surface of the adsorption element 30. Of course, in other embodiments, the drive assembly 70 may only include the driver 701, directly connecting the actuating end of the driver 701 to the adsorption element 30 to drive the adsorption element 30 to rotate on the rotating shaft 50.

[0080] In this embodiment, when indoor air passes through the adsorbent 30, the adsorbent material loaded on the adsorbent 30 adsorbs odor pollutants from the indoor air, achieving online adsorption. The purified air is discharged through the air outlet 202 of the purification duct 20. Simultaneously, the driver 701 drives the transmission gear 702 to rotate, which in turn drives the adsorbent 30 to rotate within the purification duct 20. This allows the indoor air to swirl around the adsorbent 30, ensuring sufficient contact between the indoor air and the adsorbent 30 and guaranteeing the adsorption effect. While the adsorbent 30 rotates, the adsorbent material in different areas of the adsorbent 30 can be positioned opposite the plasma component 40. This allows the high-energy electrons and strong oxidizing groups carried by the plasma wind generated by the plasma component 40 to act on the areas of the adsorbent 30 opposite to the plasma component 40, purifying and decomposing the odor pollutants adsorbed in that area of ​​the adsorbent 30 into harmless gases such as CO2 and H2O, thereby desorbing the pollutants from that area of ​​the adsorbent 30 and regenerating its adsorption capacity.

[0081] In this embodiment, the driver 701 can be a motor.

[0082] In this embodiment, the plasma assembly 40 is fan-shaped to match the diameter of the adsorbent 30, so that the plasma assembly 40 can cover the adsorbent 30 and purify and decompose the odor pollutants adsorbed by the adsorbent 30 into harmless gases such as CO2 and H2O, thereby desorbing the adsorbent 30 in that area and regenerating the adsorption capacity of the adsorbent 30 in that area.

[0083] In some embodiments, to ensure that the high-energy electrons and strong oxidizing groups carried by the plasma wind generated by the plasma assembly 40 can fully act on the area opposite the adsorbent 30 and the plasma assembly 40, the ratio of the air inlet velocity at the air inlet 201 to the plasma wind velocity of the plasma assembly is 1:2-1:4. That is, the plasma wind velocity is lower than the air inlet velocity to prevent the high-energy electrons and strong oxidizing groups from being carried away by the wind generated by the fan before they can fully act on the area opposite the adsorbent 30 and the plasma assembly 40. Preferably, the ratio of the air inlet velocity at the air inlet 201 to the plasma wind velocity of the plasma assembly is 1:3.

[0084] Figure 5 for Figure 1 A schematic diagram of the plasma assembly of the odor removal device. (Combined with...) Figure 5In some embodiments, the plasma assembly 40 includes a ground electrode 401 and a plurality of discharge electrodes 402. The ground electrode 401 has multiple through holes, and the discharge electrodes 402 are inserted into corresponding through holes, with the discharge tips of the discharge electrodes 402 facing the adsorption member 30. The discharge electrodes 402 can be needle-like or serrated, so that the discharge mode of the plasma assembly 40 is needle-like discharge or serrated discharge. For ease of processing, preferably, the discharge electrode 402 is a needle-like tip, so that the discharge mode of the plasma assembly 40 is needle-like discharge.

[0085] In this embodiment, since the discharge form of the plasma component 40 is needle tip discharge or sawtooth discharge, compared with the dielectric barrier discharge method, it can use ultra-high voltage to disinfect bacteria and viruses in indoor air, ensuring clean indoor air. At the same time, the plasma wind it generates can carry sufficient high-energy electrons and strong oxidizing groups to act on the adsorbent 30, which can fully purify and decompose the odor pollutants adsorbed by the adsorbent 30 into harmless gases such as CO2 and H2O, so as to fully desorb the adsorbent 30 and regenerate the adsorption capacity of the adsorbent 30.

[0098] Based on the same inventive concept, this application also proposes an air purifier that uses the aforementioned odor removal device. The specific structure of the odor removal device is as described in the above embodiments. Since it adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0099] In some embodiments, the housing 10 of the odor removal device can also be the housing of an air purifier. The housing 10 has a purification duct 20, which has an air inlet 201 and an air outlet 202. Indoor air enters the purification duct 20 through the air inlet 201. Since the adsorbent 30 is rotatably disposed within the purification duct 20, when indoor air passes through the adsorbent 30, the adsorbent 30 adsorbs odor pollutants from the indoor air, achieving online adsorption. The purified air is discharged through the air outlet 202 of the purification duct 20. At the same time, the adsorbent 30 rotates within the purification duct 20, allowing the indoor air to swirl around the adsorbent 30, ensuring sufficient contact between the indoor air and the adsorbent 30 and guaranteeing the adsorption effect. Since the plasma component 40 is disposed within the purification duct 20, the plasma component 40... Since the adsorbent 30 is located opposite to a portion of its end face, when the plasma assembly 40 is activated, it generates plasma wind. The high-energy electrons and strong oxidizing groups carried by the plasma wind act on the area of ​​the adsorbent 30 opposite to the plasma assembly 40, purifying and decomposing the odor pollutants adsorbed in that area of ​​the adsorbent 30 into harmless gases such as CO2 and H2O. This process desorbs the pollutants in that area of ​​the adsorbent 30, regenerating its adsorption capacity. The pollutants are then discharged into the room through the air outlet 202 of the purification duct 20, forming an internal circulation system that does not generate secondary pollution, improving indoor air comfort. The adsorbent 30 does not need to be replaced, reducing costs. The purified air, CO2, and H2O are all discharged into the room through the air outlet 202 of the purification duct 20, eliminating the need to construct a new duct and saving space.
