Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and in particular to an air purifier and a control method, a control device, a computer device, and a storage medium thereof. Background Art

[0002] Air filtration technology is a highly efficient air purification technology that uses filters to intercept dust and microorganisms in the air. As the use time increases, the dust, pollen, bacteria, viruses and other particles captured by the filters will accumulate on the filters, forming a thick layer of dirt. The bacteria and mold in the dirt will multiply and produce odor under suitable temperature and humidity conditions. The chemical substances in the dirt may also react chemically, further increasing the generation of odor. These odor molecules can be blown out from the air outlet of the air purifier along the air duct when the user uses the air purifier, causing trouble for the user and endangering human health. When the filter has an odor, the relevant technology often uses water-washing filters, disinfectants or exposure to the sun to clean the filter. Incorrect cleaning methods may also cause damage to the filter material, thereby generating odor. Summary of the invention

[0003] In view of this, the present invention provides an air purifier and a control method, a control device, a computer device, and a storage medium thereof to solve the problem of filter odor.

[0004] In a first aspect, the present invention provides an air purifier, comprising:

[0005] The filter screen is a cylindrical structure;

[0006] The plasma module is arranged on the inner side of the filter.

[0007] Beneficial effects: By setting a plasma module on the inner side of the filter, the plasma module can generate a large amount of plasma. Plasma is a highly ionized gas containing a large amount of active substances, such as free radicals, ozone and hydrogen peroxide. These active particles have strong oxidizing ability and can react with odor molecules to decompose them into harmless small molecules, such as water and carbon dioxide. When the odor molecules in the space and on the filter pass through the discharge area of ​​the plasma module, the odor can be effectively removed to protect human health. Compared with the related art of using water-washed filters, disinfectants or exposure to the sun to clean the filters, this air purifier has a better odor removal effect and does not need to remove the filters.

[0008] In an optional embodiment, air enters from the periphery of the filter and exits from the first end, and the plasma module is close to the second end of the filter.

[0009] Beneficial effect: air enters from the surrounding side of the filter and exits from the first end. By placing the plasma module close to the second end of the filter, when removing odor from the filter, the odor molecules on the filter can all pass through the discharge area of ​​the plasma module, thereby achieving more comprehensive odor removal.

[0010] In an optional embodiment, the air purifier includes an air inlet, an air outlet, a first fan and a second fan. The first fan is arranged on the outside of the filter, and is used to allow air to enter from the air inlet and blow out from the air outlet. The second fan is arranged on the inside of the filter. The power of the second fan is less than that of the first fan. The air purifier has an external circulation mode for operating the first fan and an internal circulation mode for operating the second fan.

[0011] Beneficial effects: When the air purifier operates in the external circulation mode, the external circulation mode can also be called the space odor removal mode. The air and odor molecules in the external space enter the air purifier from the air inlet under the action of the first fan. When passing through the filter, most of the foreign molecules are intercepted and adsorbed on the filter. A small number of odor molecules that are not intercepted enter the discharge area of ​​the plasma module and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge, thus completing the odor removal of the space. When the air purifier operates in the internal circulation mode, the internal circulation mode can also be called the filter odor removal mode. The second fan works, and the air circulates in a small range. The odor molecules on the filter enter the discharge area of ​​the plasma module with the second fan, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge, thus completing the odor removal of the filter.

[0012] In an optional embodiment, an odor concentration detection component is provided at the air outlet, and the air purifier includes a controller, and the controller is communicatively connected with the odor concentration detection component and the plasma module.

[0013] Beneficial effect: By setting an odor concentration detection component at the air outlet, the odor concentration at the air outlet can be detected, so that it can be judged whether the odor removal work is completed according to the odor concentration. The controller is communicated with the odor concentration detection component and the plasma module, and can control the working time of the plasma module or whether to continue working according to the odor concentration or odor level at the air outlet to ensure the odor removal effect.

[0014] In a second aspect, the present invention further provides a control method for an air purifier, which is applied to the air purifier, and the control method comprises:

[0015] Acquire a working mode of the air purifier, wherein the working mode is an external circulation mode or an internal circulation mode;

[0016] Get the odor level at the air outlet;

[0017] The plasma module working time is controlled according to the odor level at the air outlet.

[0018] Beneficial effects: By obtaining the odor level at the air outlet, the plasma module setting time is controlled according to the odor level at the air outlet. The plasma module can generate a large amount of plasma. Plasma is a highly ionized gas containing a large amount of active substances, such as free radicals (OH·, O·), ozone (O) and hydrogen peroxide (HO). These active particles have strong oxidizing ability and can react with odor molecules to decompose them into harmless small molecules, such as water and carbon dioxide. When the odor molecules in the space and on the filter pass through the discharge area of ​​the plasma module, the odor can be effectively removed to protect human health.

[0019] In an optional embodiment, after controlling the plasma module to work for a preset time, the control method further includes:

[0020] Determine whether the odor level at the air outlet is less than or equal to a preset level;

[0021] If the odor level at the air outlet is less than or equal to the preset level, the plasma module is turned off;

[0022] If the odor level at the air outlet is greater than the preset level, the plasma module is controlled to continue working.

[0023] Beneficial effect: After controlling the plasma module to work for a preset time, determine whether the odor level at the air outlet is less than or equal to the preset level. If the odor level at the air outlet is less than or equal to the preset level, it means that the purification is completed and the odor has been basically removed, so the plasma module is turned off. If the odor level at the air outlet is greater than the preset level, it means that there is still odor, so the plasma module is controlled to continue working to ensure that the odor is removed.

[0024] In an optional embodiment, if the odor level at the air outlet is greater than a preset level, the plasma module is controlled to operate according to the adjusted set time according to the odor level at the air outlet.

[0025] Beneficial effect: After controlling the plasma module to work for a preset time, if the odor level at the air outlet is greater than the preset level, it means that the plasma module cannot completely remove the odor according to the set time corresponding to the odor level. Therefore, the set time is adjusted, specifically, the set time is increased, and the plasma module is controlled to work according to the adjusted set time according to the odor level at the air outlet, thereby ensuring that the filter is deodorized.

[0026] In a third aspect, the present invention further provides a control device for an air purifier, which is applied to the air purifier, and the control device comprises:

[0027] A first acquisition module is used to acquire the working mode of the air purifier, wherein the working mode is an external circulation mode or an internal circulation mode;

[0028] The second acquisition module is used to obtain the odor level at the air outlet;

[0029] The control module is used to control the working time of the plasma module according to the odor level at the air outlet.

[0030] Beneficial effects: The second acquisition module acquires the odor level at the air outlet, and the control module controls the setting time of the plasma module according to the odor level at the air outlet. The plasma module can generate a large amount of plasma when it is working. Plasma is a highly ionized gas containing a large amount of active substances, such as free radicals (OH·, O·), ozone (O) and hydrogen peroxide (HO), etc. These active particles have strong oxidation ability and can react with odor molecules to decompose them into harmless small molecules, such as water and carbon dioxide. When the odor molecules in the space and on the filter pass through the discharge area of ​​the plasma module, the odor can be effectively removed to protect human health.

[0031] In a fourth aspect, the present invention further provides a computer device, comprising:

[0032] A memory and a processor, wherein the memory and the processor are communicatively connected to each other, computer instructions are stored in the memory, and the processor executes the control method of the air purifier by executing the computer instructions.

[0033] In a fifth aspect, the present invention further provides a computer-readable storage medium, on which computer instructions are stored, and the computer instructions are used to enable a computer to execute the control method of the air purifier. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Air filtration technology is a highly efficient air purification technology that uses filters to intercept dust and microorganisms in the air. As the use time increases, the dust, pollen, bacteria, viruses and other particles captured by the filters will accumulate on the filters, forming a thick layer of dirt. The bacteria and mold in the dirt will multiply and produce odor under suitable temperature and humidity conditions. The chemical substances in the dirt may also react chemically, further increasing the generation of odor. These odor molecules can be blown out from the air outlet of the air purifier along the air duct when the user uses the air purifier, causing trouble for the user and endangering human health. When the filter has an odor, the relevant technology often uses water-washing filters, disinfectants or exposure to the sun to clean the filter. Incorrect cleaning methods may also cause damage to the filter material, thereby generating odor.

[0046] Plasma purification technology is a highly efficient air purification technology that uses partially ionized gas to perform various physical and chemical treatments. The ionized gas contains a large number of free electrons, positive ions, negative ions, and excited atoms and molecules. When this plasma comes into contact with odor molecules, high-energy electrons can collide with the odor molecules, causing the chemical bonds of the odor molecules to break, or active species and odor molecules to react chemically to produce harmless substances. Under the combined action of multiple mechanisms, plasma technology can effectively decompose and remove odor molecules in the air.

[0047] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

[0048] According to an embodiment of the present invention, in a first aspect, an air purifier is provided, comprising a filter 1 and a plasma module 2.

[0049] The filter screen 1 is a cylindrical structure; the plasma module 2 is arranged on the inner side of the filter screen 1 .

[0050] In this embodiment, by arranging a plasma module 2 on the inner side of the filter 1, the plasma module 2 can generate a large amount of plasma when it is working. Plasma is a highly ionized gas containing a large amount of active substances, such as free radicals (OH·, O·), ozone (O) and hydrogen peroxide (HO), etc. These active particles have strong oxidizing ability and can react with odor molecules to decompose them into harmless small molecules, such as water and carbon dioxide. When the odor molecules in the space and on the filter 1 pass through the discharge area of ​​the plasma module 2, the odor can be effectively removed to protect human health. Compared with the related art that uses water washing filter 1, disinfectant or exposure to the sun to clean the filter 1, this air purifier has a better odor removal effect and does not need to disassemble the filter 1.

[0051] Specifically in one embodiment, Figure 1 As shown, the filter screen 1 is cylindrical.

[0052] Specifically in one embodiment, the filter 1 is a HEPA filter 1. In the related art, the air purifier mainly absorbs and intercepts various odors through the HEPA filter 1. However, in actual use, since the adsorption capacity of the filter 1 will gradually weaken with the increase of the use time, when the filter 1 is not replaced, the air purifier's odor removal effect in the room with high concentration is weakened. In this embodiment, the plasma module 2 and the filter 1 cooperate to remove the odor gas in the space, improve the user experience, and protect human health.

[0053] It should be noted that the filter 1 can have circumferential air inlet and end air outlet; or can have end air inlet and circumferential air outlet.

[0054] In one embodiment, air enters from the periphery of the filter 1 and exits from the first end, and the plasma module 2 is close to the second end of the filter 1 .

[0055] In this embodiment, air enters from the peripheral side of the filter 1 and exits from the first end. By placing the plasma module 2 close to the second end of the filter 1, when removing odor from the filter 1, the odor molecules on the filter 1 can all pass through the discharge area of ​​the plasma module 2, thereby achieving more comprehensive odor removal.

[0056] Specifically in one embodiment, the area inside the filter 1 can be divided into an upper half and a lower half, the air is discharged from the upper end of the filter 1, and the plasma module 2 is arranged in the lower half.

[0057] In one embodiment, the air purifier includes an air inlet, an air outlet, a first fan and a second fan 3. The first fan is arranged on the outside of the filter 1, and is used to allow air to enter from the air inlet and blow out from the air outlet. The second fan 3 is arranged on the inside of the filter 1. The power of the second fan 3 is less than that of the first fan. The air purifier has an external circulation mode for making the first fan work and an internal circulation mode for making the second fan 3 work.

[0058] In this embodiment, when the air purifier operates in the external circulation mode, the external circulation mode can also be called the space odor removal mode. The air and odor molecules in the external space enter the air purifier from the air inlet under the action of the first fan. When passing through the filter 1, most of the foreign molecules are intercepted and adsorbed on the filter 1. A small number of odor molecules that are not intercepted enter the discharge area of ​​the plasma module 2 and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge, thereby completing the odor removal of the space. When the air purifier operates in the internal circulation mode, the internal circulation mode can also be called the filter 1 odor removal mode. The second fan 3 works, and the air circulates in a small range. The odor molecules on the filter 1 enter the discharge area of ​​the plasma module 2 with the second fan 3, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge, thereby completing the odor removal of the filter 1.

[0059] Specifically in one embodiment, the second fan 3 is disposed on a side of the plasma module 2 away from the first end of the filter 1 , specifically, on the lower side of the plasma module 2 .

[0060] In one embodiment, an odor concentration detection component is provided at the air outlet, and the air purifier includes a controller, which is communicatively connected with the odor concentration detection component and the plasma module 2.

[0061] In this embodiment, by setting an odor concentration detection component at the air outlet, the odor concentration at the air outlet can be detected, so that it can be judged whether the deodorization work is completed according to the odor concentration. The controller is communicated with the odor concentration detection component and the plasma module 2, and can control the working time of the plasma module 2 or whether to continue working according to the odor concentration or odor level at the air outlet to ensure the deodorization effect.

[0062] Specifically in one embodiment, the odor level can be obtained according to the odor concentration at the air outlet. When the air purifier runs in the external circulation mode, the external circulation mode can also be called the space odor removal mode. The air and odor molecules in the external space enter the air purifier from the air inlet under the action of the first fan. When passing through the filter 1, most of the foreign molecules are intercepted and adsorbed on the filter 1. A small number of odor molecules that are not intercepted enter the discharge area of ​​the plasma module 2 and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge. After the plasma module 2 runs for a set time, it is determined whether the odor level at the air outlet is less than or equal to 1. If the odor level is greater than 1, the plasma module 2 continues to run for the set time corresponding to the odor level until the odor level is ≤1, and the space odor removal is completed. When the air purifier operates in the internal circulation mode, which can also be called the filter 1 odor removal mode, the second fan 3 works, and the air circulates in a small range. The odor molecules on the filter 1 enter the discharge area of ​​the plasma module 2 with the second fan 3, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge. After the plasma module 2 runs for a set time, it is determined whether the odor level at the air outlet is less than or equal to 1. If the odor level is greater than 1, the plasma module 2 continues to run for the set time corresponding to the odor level until the odor level is ≤1, thereby completing the odor removal of the filter 1.

[0063] Specifically in one embodiment, the space odor removal mode is mainly used in situations where there is a strong odor in the room. For example, if there is a strong odor after the user has finished eating hot pot indoors, the odor in the room can be removed by turning on the space odor removal mode.

[0064] The odor removal mode for filter 1 is used to remove odors from filter 1. In actual use, since the adsorption capacity of filter 1 will gradually weaken with the increase of usage time, by turning on the odor removal mode for filter 1, the odor of filter 1 can be removed, thereby improving the user experience and protecting human health.

[0065] According to an embodiment of the present invention, in a second aspect, a control method for an air purifier is provided, which is applied to the air purifier provided in the above embodiment, and the control method includes:

[0066] Get the working mode of the air purifier, which is external circulation mode or internal circulation mode;

[0067] Get the odor level at the air outlet;

[0068] The working time of the plasma module 2 is controlled according to the odor level at the air outlet.

[0069] In this embodiment, by obtaining the odor level at the air outlet, the working setting time of the plasma module 2 is controlled according to the odor level at the air outlet. The plasma module 2 can generate a large amount of plasma when it is working. Plasma is a highly ionized gas containing a large amount of active substances, such as free radicals (OH·, O·), ozone (O) and hydrogen peroxide (HO), etc. These active particles have strong oxidizing ability and can react with odor molecules to decompose them into harmless small molecules, such as water and carbon dioxide. When the odor molecules in the space and on the filter 1 pass through the discharge area of ​​the plasma module 2, the odor can be effectively removed to protect human health.

[0070] Specifically in one embodiment, an odor concentration detection component is provided at the air outlet to detect the odor concentration at the air outlet, and the odor level is obtained according to the odor concentration.

[0071] Specifically in one embodiment, the user selects the working mode according to the actual situation. When the user selects the external circulation mode, the air and odor molecules in the external space enter the air purifier from the air inlet under the action of the first fan. When passing through the filter 1, most of the foreign molecules are intercepted and adsorbed on the filter 1, and a small number of odor molecules that are not intercepted enter the discharge area of ​​the plasma module 2, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge, thereby completing the deodorization of the space.

[0072] When the user selects the internal circulation mode, the second fan 3 works, and the air circulates in a small range. The odor molecules on the filter 1 enter the discharge area of ​​the plasma module 2 along the second fan 3, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances produced by the discharge, thereby completing the deodorization of the filter 1.

[0073] Running time (h) Smell experience (before and after power on) Odor intensity 7.5 Pungent odor → Significantly reduced 4→3 8.5 Obvious smoke smell → Removal of typical smoke smell 3→2 8.5 Smell → Slight smell after shutting down 2→2 6.5 Slightly smelly → The odor has been basically removed 2→1

[0074] Table 1

[0075] Odor intensity Judgment content 0 Odorless 1 Seemingly existent 2 Slightly smelly 3 Obviously taste 4 Strong taste 5 Unbearable

[0076] Table 2

[0077] Specifically in one embodiment, combined with Table 1, after the user selects the working mode of the air purifier, the odor level at the air outlet is detected and obtained. If the odor level is 4, the plasma module 2 is operated for 7.5+8.5+8.5+6.5=31h, which can reduce the odor level from 4 to 1.

[0078] It should be noted that since the specific value of the odor intensity value represents a concentration range, after a period of time, the odor perception may change but the odor level may not change significantly. For example, in Table 1, the odor experience decreases from having an odor to a slight odor after shutting down, but the odor level does not change. Table 2 shows the relationship between the national standard odor intensity and the odor experience. The national standard does not give the relationship between the specific concentration range value and the odor level, and the judgment is only made by smell.

[0079] In one embodiment, after controlling the plasma module 2 to work for a preset time, the control method further includes:

[0080] Determine whether the odor level at the air outlet is less than or equal to a preset level;

[0081] If the odor level at the air outlet is less than or equal to the preset level, the plasma module 2 is turned off;

[0082] If the odor level at the air outlet is greater than the preset level, the plasma module 2 is controlled to continue working.

[0083] In this embodiment, after controlling the plasma module 2 to work for a preset time, it is determined whether the odor level at the air outlet is less than or equal to the preset level. If the odor level at the air outlet is less than or equal to the preset level, it means that the purification is completed and the odor has been basically removed, so the plasma module 2 is turned off. If the odor level at the air outlet is greater than the preset level, it means that there is still odor, so the plasma module 2 is controlled to continue working to ensure that the odor is removed.

[0084] Specifically in one embodiment, the preset level is 1. After the plasma module 2 is controlled to work for a preset time, it is determined whether the odor level at the air outlet is less than or equal to 1. If the odor level at the air outlet is less than or equal to 1, it means that the purification is completed and the odor has been basically removed, so the plasma module 2 is turned off. If the odor level at the air outlet is greater than 1, it means that there is still odor, so the plasma module 2 is controlled to continue working to ensure that the odor is removed.

[0085] Specifically in one embodiment, when the air purifier operates in the external circulation mode, the air and odor molecules in the external space enter the air purifier from the air inlet under the action of the first fan. When passing through the filter 1, most of the foreign molecules are intercepted and adsorbed on the filter 1, and a small number of odor molecules that are not intercepted enter the discharge area of ​​the plasma module 2, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge. After the plasma module 2 runs for a set time, it is determined whether the odor level at the air outlet is less than or equal to 1. If the odor level is greater than 1, the plasma module 2 continues to run for the set time corresponding to the odor level until the odor level is ≤1, thereby completing the deodorization of the space. When the air purifier operates in the internal circulation mode, which can also be called the filter 1 odor removal mode, the second fan 3 works, and the air circulates in a small range. The odor molecules on the filter 1 enter the discharge area of ​​the plasma module 2 with the second fan 3, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge. After the plasma module 2 runs for a set time, it is determined whether the odor level at the air outlet is less than or equal to 1. If the odor level is greater than 1, the plasma module 2 continues to run for the set time corresponding to the odor level until the odor level is ≤1, thereby completing the odor removal of the filter 1.

[0086] In one embodiment, if the odor level at the air outlet is greater than a preset level, the plasma module 2 is controlled to operate according to the adjusted set time according to the odor level at the air outlet.

[0087] In this embodiment, after controlling the plasma module 2 to work for a preset time, if the odor level at the air outlet is greater than the preset level, it means that the plasma module 2 cannot completely remove the odor according to the set time corresponding to the odor level. Therefore, the set time is adjusted, specifically, the set time is increased, and the plasma module 2 is controlled to work according to the adjusted set time according to the odor level at the air outlet, thereby ensuring that the filter 1 is deodorized.

[0088] Specifically in one embodiment, after the user selects the working mode of the air purifier, the odor level at the air outlet is detected and obtained. If the odor level is 4, the plasma module 2 is operated for 7.5+8.5+8.5+6.5=31 hours. If the odor level at the air outlet is 2, and the initial setting time corresponding to the odor level 2 is 6.5 hours, the initial setting time is adjusted, for example, by increasing 2 hours, so that the plasma module 2 is controlled to operate for 8.5 hours.

[0089] According to an embodiment of the present invention, in a third aspect, a control device for an air purifier is provided, which is applied to the air purifier provided in the above embodiment, and the control device includes:

[0090] A first acquisition module is used to acquire the working mode of the air purifier, which working mode is an external circulation mode or an internal circulation mode;

[0091] The second acquisition module is used to obtain the odor level at the air outlet;

[0092] The control module is used to control the working time of the plasma module 2 according to the odor level at the air outlet.

[0093] In this embodiment, the second acquisition module acquires the odor level at the air outlet, and the control module controls the setting time of the plasma module 2 according to the odor level at the air outlet. The plasma module 2 can generate a large amount of plasma when it is working. Plasma is a highly ionized gas containing a large amount of active substances, such as free radicals (OH·, O·), ozone (O) and hydrogen peroxide (HO), etc. These active particles have strong oxidation ability and can react with odor molecules to decompose them into harmless small molecules, such as water and carbon dioxide. When the odor molecules in the space and on the filter 1 pass through the discharge area of ​​the plasma module 2, the odor can be effectively removed to protect human health.

[0094] Specifically in one embodiment, an odor concentration detection component is provided at the air outlet to detect the odor concentration at the air outlet, and the odor level is obtained according to the odor concentration.

[0095] Specifically in one embodiment, the user selects the working mode according to the actual situation. When the user selects the external circulation mode, the air and odor molecules in the external space enter the air purifier from the air inlet under the action of the first fan. When passing through the filter 1, most of the foreign molecules are intercepted and adsorbed on the filter 1, and a small number of odor molecules that are not intercepted enter the discharge area of ​​the plasma module 2, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge, thereby completing the deodorization of the space.

[0096] When the user selects the internal circulation mode, the second fan 3 works, and the air circulates in a small range. The odor molecules on the filter 1 enter the discharge area of ​​the plasma module 2 along the second fan 3, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances produced by the discharge, thereby completing the deodorization of the filter 1.

[0097] In one embodiment, after controlling the plasma module 2 to work for a preset time, the control method further includes:

[0098] A judgment module, used to judge whether the odor level at the air outlet is less than or equal to a preset level after the plasma module 2 is controlled to work for a preset time;

[0099] The control module is used to shut down the plasma module 2 when the odor level at the air outlet is less than or equal to the preset level; and to control the plasma module 2 to continue working when the odor level at the air outlet is greater than the preset level.

[0100] In this embodiment, after controlling the plasma module 2 to work for a preset time, the judgment module judges whether the odor level at the air outlet is less than or equal to the preset level. If the odor level at the air outlet is less than or equal to the preset level, it means that the purification is completed and the odor has been basically removed, so the plasma module 2 is turned off. If the odor level at the air outlet is greater than the preset level, it means that there is still odor, so the plasma module 2 is controlled to continue working to ensure that the odor is removed.

[0101] Specifically in one embodiment, the preset level is 1. After the plasma module 2 is controlled to work for a preset time, the judgment module judges whether the odor level at the air outlet is less than or equal to 1. If the odor level at the air outlet is less than or equal to 1, it means that the purification is completed and the odor has been basically removed, so the plasma module 2 is turned off. If the odor level at the air outlet is greater than 1, it means that there is still odor, so the plasma module 2 is controlled to continue working to ensure that the odor is removed.

[0102] Specifically in one embodiment, when the air purifier operates in the external circulation mode, the air and odor molecules in the external space enter the air purifier from the air inlet under the action of the first fan. When passing through the filter 1, most of the foreign molecules are intercepted and adsorbed on the filter 1, and a small number of odor molecules that are not intercepted enter the discharge area of ​​the plasma module 2, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge. After the plasma module 2 runs for a set time, the judgment module determines whether the odor level at the air outlet is less than or equal to 1. If the odor level is greater than 1, the plasma module 2 continues to run for the set time corresponding to the odor level until the odor level is ≤1, thereby completing the deodorization of the space. When the air purifier operates in the internal circulation mode, which can also be called the filter 1 odor removal mode, the second fan 3 works, and the air circulates in a small range. The odor molecules on the filter 1 enter the discharge area of ​​the plasma module 2 with the second fan 3, and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge. After the plasma module 2 runs for a set time, the judgment module judges whether the odor level at the air outlet is less than or equal to 1. If the odor level is greater than 1, the plasma module 2 continues to run for the set time corresponding to the odor level until the odor level is ≤1, thereby completing the odor removal of the filter 1.

[0103] In one embodiment, the control module is used to control the plasma module 2 to operate according to the adjusted set time according to the odor level at the air outlet when the odor level at the air outlet is greater than a preset level.

[0104] In this embodiment, after controlling the plasma module 2 to work for a preset time, if the odor level at the air outlet is greater than the preset level, it means that the plasma module 2 cannot completely remove the odor according to the set time corresponding to the odor level, so the set time is adjusted, specifically increasing the set time, and controlling the plasma module 2 to work according to the adjusted set time according to the odor level at the air outlet, thereby ensuring that the filter 1 is deodorized. The further functional description of each of the above modules and units is the same as that of the above corresponding embodiment, and will not be repeated here.
