Description

Technical Field

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

[0003] With the increasing status of pets in families, pet health and the cleanliness of the home environment have become the focus of pet owners' attention. The air purifiers in related technologies are mainly designed for the human living environment and lack consideration for pets. The air environment near pets is usually relatively poor, which affects the health of humans and pets. Summary of the Invention

[0004] In view of this, the present invention provides a control method for an air purification device, a control device, a computer device, and a storage medium to solve the problem of poor air quality near pets.

[0005] In a first aspect, the present invention provides a control method for an air purification device, including:

[0006] Obtaining the location where the pet is located;

[0007] Controlling the air outlet of the air purification device to face the location where the pet is located.

[0008] Beneficial Effects: By obtaining the location where the pet is located in real time and controlling the air outlet of the air purification device to face the location where the pet is located, it is possible to ensure the efficient purification of the air around the pet and reduce the allergen and odor problems caused by the pet.

[0009] In an optional embodiment, the air purification device includes a filter screen and a plasma module disposed inside the filter screen. The air purification device has a filter screen deodorization mode. When the filter screen deodorization mode is turned on, the control method includes:

[0010] Obtaining the odor level inside the filter screen;

[0011] Controlling the working set time of the plasma module according to the odor level inside the filter screen.

[0012] Beneficial effects: By obtaining the odor level inside the filter screen and controlling the working set time of the plasma module according to the odor level inside the filter screen, a large amount of plasma can be generated when the plasma module works. Plasma is a highly ionized gas containing a large number of active substances such as free radicals (OH·, O·), ozone (O3), and hydrogen peroxide (H2O2). 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 screen pass through the discharge area of the plasma module, effective removal of odors can be achieved, protecting human health.

[0013] In an optional embodiment, the air purification device further includes an ultraviolet module disposed inside the filter screen, and the control method further includes:

[0014] Obtain the ozone concentration at the air outlet;

[0015] Determine whether the ozone concentration at the air outlet is greater than or equal to a preset concentration;

[0016] If so, turn on the ultraviolet module.

[0017] Beneficial effects: When the plasma module works, ozone is generated. By detecting the ozone concentration at the air outlet in real time, if the ozone concentration at the air outlet is greater than or equal to the preset concentration, it means that the ozone concentration is relatively high and does not meet the ozone emission standard. Then turn on the ultraviolet module, and the ultraviolet starts to decompose the ozone generated by high-voltage discharge, ensuring that the ozone concentration at the air outlet meets the emission standard.

[0018] In an optional embodiment, the control method further includes:

[0019] Adjust the input current of the ultraviolet module according to the ozone concentration at the air outlet.

[0020] Beneficial effects: Adjust the input current of the ultraviolet module according to the ozone concentration at the air outlet, and then the ultraviolet intensity can be adjusted, so as to ensure that the ozone concentration at the air outlet meets the emission standard.

[0021] In an optional embodiment, after controlling the working set time of the plasma module, the control method further includes:

[0022] Determine whether the odor level inside the filter screen is less than or equal to a preset level;

[0023] If the odor level inside the filter screen is less than or equal to the preset level, turn off the plasma module;

[0024] If the odor level inside the filter screen is greater than the preset level, control the plasma module to continue working.

[0025] Beneficial effects: After controlling the plasma module to work for a preset time, it is judged whether the odor level inside the filter is less than or equal to the preset level. If the odor level inside the filter is less than or equal to the preset level, it indicates that the purification is completed and the odor has been basically removed. Therefore, the plasma module is turned off. If the odor level inside the filter is greater than the preset level, it indicates that there is still odor. Therefore, the plasma module is controlled to continue working to ensure the removal of the odor.

[0026] In an alternative embodiment, if the odor level inside the filter is greater than the preset level, the plasma module is controlled to work according to the adjusted set time based on the odor level inside the filter.

[0027] Beneficial effects: Since the plasma discharge intensity is related to the ambient temperature and humidity, different temperature and humidity conditions result in different discharge intensities. After the set working time, the odor may not be completely removed. After controlling the plasma module to work for the set time, if the odor level inside the filter is greater than the preset level, it indicates 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 by increasing the set time, and the plasma module is controlled to work according to the adjusted set time based on the odor level inside the filter, so as to ensure the removal of the odor from the filter.

[0028] In an alternative embodiment, the air purification device includes a filter and an ultraviolet module disposed inside the filter. The air purification device has a filter sterilization mode. When the filter sterilization mode is turned on, the control method includes:

[0029] Turn on the ultraviolet module for a preset time.

[0030] Beneficial effects: After the ultraviolet module is turned on, the ultraviolet module emits ultraviolet rays. When the ultraviolet rays irradiate the bacteria on the surface of the filter, the ultraviolet rays can break the chemical bonds in the DNA molecules, resulting in the breakage of the DNA strands or the formation of thymine dimers, hindering the normal replication and transcription processes of DNA, causing the microorganisms to be unable to grow and reproduce normally, and successfully killing the bacteria on the inner surface of the filter, completing the disinfection of the filter.

[0031] In a second aspect, the present invention also provides a control device for an air purification device, including:

[0032] A first acquisition module for acquiring the location of the pet;

[0033] A first control module for controlling the air outlet of the air purification device to face the location of the pet.

[0034] In a third aspect, the present invention also provides a computer device, including:

[0035] A memory and a processor, which are communicatively connected to each other. Computer instructions are stored in the memory, and the processor executes the control method of the air purification device by executing the computer instructions.

[0036] In a fourth aspect, the present invention further provides a computer-readable storage medium, on which computer instructions are stored, and the computer instructions are used to cause a computer to execute the control method of the air purification device. Description of the Drawings

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0046] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] As the status of pets in the family has been increasing day by day, pet health and the cleanliness of the home environment have become the focus of pet owners' attention. The air purifiers in the related art are mainly designed for the human living environment and lack consideration for pets. The air environment near pets is usually relatively poor, which affects the health of humans and pets.

[0050] In addition, the air purifier includes a filter screen, which is an efficient air purification technology that uses the filter screen to intercept dust and microorganisms in the air. As the use time increases, the particulate matter such as dust, pollen, bacteria, and viruses captured by the filter screen will accumulate on the filter screen, forming a thick layer of dirt. The bacteria and molds in this dirt will reproduce and generate odors under suitable temperature and humidity conditions, and the chemical substances in the dirt may also undergo chemical reactions, further increasing the generation of odors. These generated odor molecules can be blown out from the air outlet of the purifier along the air duct when the user uses the air purifier, causing trouble to the user and endangering the physical health of the human body.

[0051] The following combines Figures 1 to 4 , to describe the embodiments of the present invention.

[0052] According to an embodiment of the present invention, in a first aspect, an air purification device is provided.

[0053] In one embodiment, the bottom of the air purification device is provided with universal wheels, and the orientation of the air outlet of the air purification device can be adjusted through the universal wheels.

[0054] In one embodiment, the air purification device is provided with a camera and a motion sensor, which can identify the behavior patterns and positions of pets, and adjust the wind speed of the air purification device and the orientation of the air outlet according to the positions of the pets to ensure the efficient purification of the air around the pets and reduce the problems of allergens and odors caused by pets.

[0055] In one embodiment, as Figure 1 shown, it includes a filter screen 1, a plasma module 2 and an ultraviolet module arranged inside the filter screen 1.

[0056] When the plasma module 2 works, it can generate a large amount of plasma. Plasma is a highly ionized gas containing a large number of active substances, such as free radicals (OH·, O·), ozone (O3) and hydrogen peroxide (H2O2), 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 screen 1 pass through the discharge area of the plasma module 2, effective removal of odors can be achieved, protecting human health.

[0057] Specifically, in one embodiment, as Figure 1 shown, the filter screen 1 is cylindrical.

[0058] Specifically, in one embodiment, the filter screen 1 is a HEPA filter screen 1. The air purifier mainly adsorbs and intercepts various odors through the HEPA filter screen 1. However, in the actual use process, since the adsorption capacity of the filter screen 1 will gradually weaken with the increase of the use time, when the filter screen 1 is not replaced, the effect of removing odors in a room with a high concentration of odors by the air purifier weakens. By the cooperation of the plasma module 2 and the filter screen 1 to remove the odor gas in the space and on the filter screen 1, the user experience can be improved and human health can be protected.

[0059] It should be noted that the filter screen 1 can have circumferential air inlet and end air outlet; or end air inlet and circumferential air outlet.

[0060] In one embodiment, the filter screen 1 has circumferential air inlet and first-end air outlet, and the plasma module 2 is close to the second end of the filter screen 1. With the circumferential air inlet and first-end air outlet of the filter screen 1, by placing the plasma module 2 close to the second end of the filter screen 1, when removing odors from the filter screen 1, all the odor molecules on the filter screen 1 can pass through the discharge area of the plasma module 2, so that odors can be removed more comprehensively.

[0061] Specifically, in one embodiment, the area inside the filter screen 1 can be divided into an upper half and a lower half. The upper end of the filter screen 1 discharges air, and the plasma module 2 is arranged in the lower half.

[0062] In one embodiment, the air purification device includes an air inlet, an air outlet, a first fan, and a second fan. The first fan is arranged outside the filter screen 1 and is used to make air enter from the air inlet and blow out from the air outlet. The second fan is arranged inside the filter screen 1, and the power of the second fan is less than that of the first fan. The air purification device has an external circulation mode in which the first fan operates and an internal circulation mode in which the second fan operates.

[0063] When the air purification device operates in the external circulation mode, the external circulation mode can also be called the space odor removal mode. Under the action of the first fan, the air and odor molecules in the external space enter the air purification device from the air inlet. When passing through the filter screen 1, most of the foreign molecules are intercepted and adsorbed on the filter screen 1, and a small number of un-intercepted odor molecules 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, completing the removal of odor in the space. When the air purification device operates in the internal circulation mode, the internal circulation mode can also be called the filter screen odor removal mode. The second fan operates, and the air circulates in a small range. The odor molecules on the filter screen 1 enter the discharge area of the plasma module 2 along with the second fan and are oxidized and decomposed into H2O, CO2 or other small molecules by the active substances generated by the discharge, completing the removal of odor from the filter screen 1.

[0064] Specifically, in one embodiment, the second fan is arranged on one side of the first end of the plasma module 2 away from the filter screen 1, specifically located below the plasma module 2.

[0065] In one embodiment, an odor concentration detection component is arranged at the air outlet. The air purification device includes a controller, and the controller is communicatively connected to the odor concentration detection component and the plasma module 2.

[0066] By arranging an odor concentration detection component at the air outlet, the odor concentration at the air outlet can be detected. Therefore, it can be judged whether the odor removal work is completed according to the odor concentration. The controller is communicatively connected to the odor concentration detection component and the plasma module 2, and can control the working duration or whether to continue working of the plasma module 2 according to the odor concentration or odor level at the air outlet to ensure the odor removal effect.

[0067] Specifically, in one embodiment, the odor level can be obtained based on the odor concentration at the air outlet. When the air purification device operates in the external circulation mode, which can also be referred to as the space odor removal mode, the air and odor molecules in the external space enter the interior of the air purification device 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 un-intercepted odor molecules 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 operates for a set time, it is judged whether the odor level at the air outlet is less than or equal to 1. If the odor level > 1, the plasma module 2 is made to continue operating for the set time corresponding to the odor level until the odor level ≤ 1, thus completing the removal of odors in the space. When the air purification device operates in the internal circulation mode, which can also be referred to as the filter odor removal mode, the second fan 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 with the second fan 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 operates for a set time, it is judged whether the odor level at the air outlet is less than or equal to 1. If the odor level > 1, the plasma module 2 is made to continue operating for the set time corresponding to the odor level until the odor level ≤ 1, thus completing the removal of odors from the filter 1.

[0068] Specifically, in one embodiment, the space odor removal mode is mainly used in cases where there is a strong odor in the room. For example, after the user eats hot pot indoors and the odor is strong, the space odor removal mode can be turned on to remove the odor in the indoor space.

[0069] The filter odor removal mode is used to remove odors from the filter 1. In the actual use process, since the adsorption capacity of the filter 1 gradually weakens with the increase of the use time, by turning on the filter odor removal mode, the odor of the filter 1 can be removed, improving the user experience and protecting human health.

[0070] The air purification device also has a filter sterilization mode. The ultraviolet module emits ultraviolet light. When the ultraviolet light irradiates the bacteria on the surface of the filter 1, the ultraviolet light can break the chemical bonds in the DNA molecules, resulting in the breakage of the DNA strand or the formation of thymine dimers, hindering the normal replication and transcription processes of DNA, causing the microorganisms to be unable to grow and reproduce normally, and successfully killing the bacteria on the inner surface of the filter 1, thus completing the disinfection of the filter 1.

[0071] Specifically, in one embodiment, the ultraviolet module includes a plurality of ultraviolet lamp beads 4 evenly distributed along the circumference, which can perform 360° sterilization on the inner surface of the cylindrical filter 1.

[0072] Specifically, in one embodiment, as Figure 2As shown, the ultraviolet module includes four lamp beads 4, and the irradiation angle of each lamp bead 4 is A, where A > 120°.

[0073] Specifically, in one embodiment, the ultraviolet module is installed on the lamp socket 3, and the plasma module 2 is disposed below the lamp socket 3.

[0074] In one embodiment, the air purification device includes a body and a laser cat - teasing device disposed on the body. By setting the laser cat - teasing device on the body, after the laser cat - teasing device is turned on, it can emit laser light and interact with pets, enhancing the sense of interaction and entertainment.

[0075] In one embodiment, the laser cat - teasing device includes a plurality of laser lamps spaced circumferentially along the body. The positions and angles of the laser light emitted by each laser lamp are different. Therefore, by controlling different laser lamps to emit light, the laser position can be continuously changed to enhance the interaction with pets.

[0076] In one embodiment, the body is provided with a first detection component, and the air purification device includes a controller. The controller is communicatively connected to the first detection component and the laser cat - teasing device. The controller can control the laser cat - teasing device to operate when the first detection component detects that a pet is approaching the body.

[0077] According to an embodiment of the present invention, in a second aspect, there is provided a control method for an air purification device, including:

[0078] Obtain the position of the pet;

[0079] Control the air outlet of the air purification device to face the position where the pet is located.

[0080] In this embodiment, by obtaining the position of the pet in real - time and controlling the air outlet of the air purification device to face the position where the pet is located, it is possible to ensure the efficient purification of the air around the pet and reduce the problems of allergens and odors caused by the pet.

[0081] In one embodiment, the air purification device includes a filter screen 1 and a plasma module 2 disposed inside the filter screen 1. The air purification device has a filter - screen odor - removal mode. When the filter - screen odor - removal mode is turned on, the control method includes:

[0082] Obtain the odor level inside the filter screen 1;

[0083] Control the working set time of the plasma module 2 according to the odor level inside the filter screen 1.

[0084] In this embodiment, by obtaining the odor level inside the filter screen 1 and controlling the working set time of the plasma module 2 according to the odor level inside the filter screen 1, a large amount of plasma can be generated when the plasma module 2 works. Plasma is a highly ionized gas containing a large number of active substances such as free radicals (OH·, O·), ozone (O3), and hydrogen peroxide (H2O2). 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 screen 1 pass through the discharge area of the plasma module 2, effective removal of odors can be achieved to protect human health.

[0085] Specifically, in one embodiment, an odor concentration detection component is provided inside the filter screen 1 to detect the odor concentration inside the filter screen 1, and the odor level is obtained based on the odor concentration.

[0086] Running time (h) Smell experience (before and after startup) Smell intensity 7.5 Pungent smell → significantly reduced 4→3 8.5 Obvious smoky smell → representative smell of smoke removed 3→2 8.5 Smelly → slightly smelly after shutdown 2→2 6.5 Slightly smelly → strange smell basically removed 2→1

[0087] Table 1

[0088] Smell intensity Judgment content 0 Odorless 1 Barely perceptible 2 Slightly smelly 3 Obviously smelly 4 Strongly smelly 5 Intolerable

[0089] Table 2

[0090] Specifically, in one embodiment, in combination with Table 1, the odor level inside the filter screen 1 is detected and obtained. If the odor level is 4, the plasma module 2 is made to work for 7.5 + 8.5 + 8.5 + 6.5 = 31 h, and the odor level can be reduced from 4 to 1.

[0091] It should be noted that since the specific value of the odor intensity value represents a concentration range, there will be a situation where after a period of time, the odor sensation changes but the odor level does not change significantly. For example, in Table 1, the odor experience changes from having an odor to slightly having an odor after turning off, 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 only judges by smelling.

[0092] In one embodiment, the air purification device further includes an ultraviolet module provided inside the filter screen 1, and the control method further includes:

[0093] Obtain the ozone concentration at the air outlet;

[0094] Judge whether the ozone concentration at the air outlet is greater than or equal to the preset concentration;

[0095] If so, turn on the ultraviolet module.

[0096] In this embodiment, when the plasma module 2 is operating, ozone is generated. By detecting the ozone concentration at the air outlet in real time, if the ozone concentration at the air outlet is greater than or equal to the preset concentration, it indicates that the ozone concentration is relatively high and does not meet the ozone emission standard. Then the ultraviolet module is turned on, and the ultraviolet light starts to decompose the ozone generated by high-voltage discharge to ensure that the ozone concentration at the air outlet meets the emission standard.

[0097] Specifically, if the ozone concentration at the air outlet is less than the preset concentration, the ultraviolet module is turned off.

[0098] In one embodiment, the control method further includes:

[0099] Adjusting the input current of the ultraviolet module according to the ozone concentration at the air outlet.

[0100] In this embodiment, by adjusting the input current of the ultraviolet module according to the ozone concentration at the air outlet, the ultraviolet intensity can be adjusted, thereby ensuring that the ozone concentration at the air outlet meets the emission standard.

[0101] In one embodiment, after the plasma module 2 has been operating for a set time, the control method further includes:

[0102] Judging whether the odor level inside the filter screen 1 is less than or equal to the preset level;

[0103] If the odor level inside the filter screen 1 is less than or equal to the preset level, the plasma module 2 is turned off;

[0104] If the odor level inside the filter screen 1 is greater than the preset level, the plasma module 2 is controlled to continue operating.

[0105] After the plasma module 2 has been operating for the preset time, judge whether the odor level inside the filter screen 1 is less than or equal to the preset level. If the odor level inside the filter screen 1 is less than or equal to the preset level, it indicates that the purification is over and the odor has been basically removed. Therefore, the plasma module 2 is turned off. If the odor level inside the filter screen 1 is greater than the preset level, it indicates that there is still odor. Therefore, the plasma module 2 is controlled to continue operating to ensure that the odor is removed.

[0106] Specifically, in one embodiment, the preset level is 1. After the plasma module 2 has been operating for the preset time, judge whether the odor level inside the filter screen 1 is less than or equal to 1. If the odor level inside the filter screen 1 is less than or equal to 1, it indicates that the purification is over and the odor has been basically removed. Therefore, the plasma module 2 is turned off. If the odor level inside the filter screen 1 is greater than 1, it indicates that there is still odor. Therefore, the plasma module 2 is controlled to continue operating to ensure that the odor is removed.

[0107] In one embodiment, if the odor level inside the filter screen 1 is greater than the preset level, the plasma module 2 is controlled to operate according to the adjusted set time based on the odor level inside the filter screen 1.

[0108] In this embodiment, since the plasma discharge intensity is related to the ambient temperature and humidity, different temperature and humidity result in different discharge intensities, and the odor may not be completely removed after the set working time. After controlling the plasma module 2 to work for the set time, if the odor level inside the filter screen 1 is greater than the preset level, it indicates 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 by increasing the set time, and the plasma module 2 is controlled to operate according to the adjusted set time based on the odor level inside the filter screen 1, so as to ensure the removal of the odor from the filter screen 1.

[0109] Specifically, in one embodiment, when the user selects the odor removal mode, the odor level inside the filter screen 1 is detected and obtained. If the odor level is 4, after the plasma module 2 works for 7.5 + 8.5 + 8.5 + 6.5 = 31 h, if the odor level inside the filter screen 1 is 2, and the initial set time corresponding to the odor level 2 is 6.5 h, then the initial set time is adjusted, for example, increased by 2 h. Therefore, the plasma module 2 is controlled to work for 8.5 h.

[0110] In one embodiment, the air purification device includes a filter screen 1 and an ultraviolet module disposed inside the filter screen 1. The air purification device has a filter screen sterilization mode. When the filter screen sterilization mode is turned on, the control method includes:

[0111] Turn on the ultraviolet module for a preset time.

[0112] In this embodiment, after the ultraviolet module is turned on, the ultraviolet module emits ultraviolet rays. When the ultraviolet rays irradiate the bacteria on the surface of the filter screen 1, the ultraviolet rays can break the chemical bonds in the DNA molecules, resulting in the breakage of the DNA strand or the formation of thymine dimers, hindering the normal replication and transcription processes of DNA, causing microorganisms to be unable to grow and reproduce normally, and successfully killing the bacteria on the inner surface of the filter screen 1, thus completing the disinfection of the filter screen 1.

[0113] According to an embodiment of the present invention, in a third aspect, a control device for an air purification device is further provided, including:

[0114] A first acquisition module for acquiring the location of the pet;

[0115] A first control module for controlling the air outlet of the air purification device to face the location of the pet.

[0116] In this embodiment, the first acquisition module is used to acquire the location of the pet in real time, and the air outlet of the air purification device is controlled to face the location of the pet, which can ensure the efficient purification of the air around the pet and reduce the allergen and odor problems caused by the pet.

[0117] In one embodiment, the air purification device includes a filter screen 1 and a plasma module 2 disposed inside the filter screen 1. The air purification device has a filter screen odor removal mode. The control device includes:

[0118] A second acquisition module, configured to acquire the odor level inside the filter screen 1;

[0119] A second control module, configured to control the working set time of the plasma module 2 according to the odor level inside the filter screen 1.

[0120] In this embodiment, the second acquisition module acquires the odor level inside the filter screen 1, and the second control module controls the working set time of the plasma module 2 according to the odor level inside the filter screen 1. When the plasma module 2 works, a large amount of plasma can be generated. Plasma is a highly ionized gas containing a large number of active substances, such as free radicals (OH·, O·), ozone (O3), and hydrogen peroxide (H2O2), 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 screen 1 pass through the discharge area of the plasma module 2, effective removal of odors can be achieved, protecting human health.

[0121] Specifically, in one embodiment, an odor concentration detection component is provided inside the filter screen 1 to detect the odor concentration inside the filter screen 1, and the odor level is obtained according to the odor concentration.

[0122] In one embodiment, the air purification device further includes an ultraviolet module disposed inside the filter screen 1. The control device further includes:

[0123] A third acquisition module, configured to acquire the ozone concentration at the air outlet;

[0124] A first judgment module, configured to judge whether the ozone concentration at the air outlet is greater than or equal to a preset concentration;

[0125] A third control module, configured to turn on the ultraviolet module when the ozone concentration at the air outlet is greater than or equal to the preset concentration.

[0126] In this embodiment, when the plasma module 2 is operating, ozone is generated. The third acquisition module detects the ozone concentration at the air outlet in real time. If the ozone concentration at the air outlet is greater than or equal to the preset concentration, it indicates that the ozone concentration is high and does not meet the ozone emission standard. The third control module turns on the ultraviolet module, and the ultraviolet starts to decompose the ozone generated by high-voltage discharge to ensure that the ozone concentration at the air outlet meets the emission standard.

[0127] In one embodiment, the control device further includes:

[0128] A fourth control module, configured to adjust the input current of the ultraviolet module according to the ozone concentration at the air outlet.

[0129] In this embodiment, the input current of the ultraviolet module is adjusted according to the ozone concentration at the air outlet, and thus the ultraviolet intensity can be adjusted, so as to ensure that the ozone concentration at the air outlet meets the emission standard.

[0130] In one embodiment, the control device further includes:

[0131] A second judgment module, configured to judge whether the odor level inside the filter screen 1 is less than or equal to the preset level after the plasma module 2 has been operating for a set time;

[0132] A fifth control module, configured to turn off the plasma module 2 when the odor level inside the filter screen 1 is less than or equal to the preset level, and control the plasma module 2 to continue operating when the odor level inside the filter screen 1 is greater than the preset level.

[0133] After the plasma module 2 has been operating for the preset time, the second judgment module judges whether the odor level inside the filter screen 1 is less than or equal to the preset level. If the odor level inside the filter screen 1 is less than or equal to the preset level, it indicates that the purification is completed and the odor has been basically removed, so the plasma module 2 is turned off. If the odor level inside the filter screen 1 is greater than the preset level, it indicates that there is still odor, so the plasma module 2 is controlled to continue operating to ensure that the odor is removed.

[0134] Specifically, in one embodiment, the preset level is 1. After the plasma module 2 has been operating for the preset time, it is judged whether the odor level inside the filter screen 1 is less than or equal to 1. If the odor level inside the filter screen 1 is less than or equal to 1, it indicates that the purification is completed and the odor has been basically removed, so the plasma module 2 is turned off. If the odor level inside the filter screen 1 is greater than 1, it indicates that there is still odor, so the plasma module 2 is controlled to continue operating to ensure that the odor is removed.

[0135] In one embodiment, if the odor level inside the filter screen 1 is greater than the preset level, the plasma module 2 is controlled to operate according to the adjusted set time according to the odor level inside the filter screen 1.

[0136] In this embodiment, since the plasma discharge intensity is related to the ambient temperature and humidity, different temperature and humidity result in different discharge intensities, and the odor may not be completely removed after the working set time. After the plasma module 2 works for the set time, if the odor level inside the filter 1 is greater than the preset level, it indicates 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 by increasing the set time, and the plasma module 2 is controlled to work according to the adjusted set time based on the odor level inside the filter 1, so as to ensure the removal of the odor from the filter 1.

[0137] Specifically, in one embodiment, when the user selects the odor removal mode, the odor level inside the filter 1 is detected and obtained. If the odor level is 4, after the plasma module 2 works for 7.5 + 8.5 + 8.5 + 6.5 = 31 h, if the odor level inside the filter 1 is 2, and the initial set time corresponding to the odor level 2 is 6.5 h, then the initial set time is adjusted, for example, increased by 2 h. Therefore, the plasma module 2 is controlled to work for 8.5 h.

[0138] In one embodiment, the air purification device includes a filter 1 and an ultraviolet module disposed inside the filter 1. The air purification device has a filter sterilization mode, and the control device includes:

[0139] A sixth control module for turning on the ultraviolet module for a preset time when the filter sterilization mode is turned on.

[0140] In this embodiment, after the ultraviolet module is turned on, the ultraviolet module emits ultraviolet rays. When the ultraviolet rays irradiate the bacteria on the surface of the filter 1, the ultraviolet rays can break the chemical bonds in the DNA molecule, resulting in the breakage of the DNA strand or the formation of thymine dimers, hindering the normal replication and transcription processes of DNA, causing the microorganisms to be unable to grow and reproduce normally, and successfully killing the bacteria on the inner surface of the filter 1, thus completing the disinfection of the filter 1.
