Description

Technical Field

[0001] This application relates to the technical field of air purifiers, and in particular, to a control method for an air purifier and an air purifier. Background Art

[0002] In related technologies, the main functions of an air purifier are to adsorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria and allergens, etc.). After the air purifier is used for a long time, a large amount of dust will adhere to the air inlet side of the filter element, resulting in an increase in the resistance of the filter element, thereby affecting the air volume of the whole machine and the air purification effect. At the same time, most air purifiers detect the air components through particulate matter sensors and gaseous pollutant sensors, such as PM2.5 sensors or formaldehyde sensors, to reflect the purification effect of the air purifier. However, such air purifiers still cannot enable users to directly experience the effect of the air purifier. Summary of the Invention

[0003] This application aims to at least solve one of the technical problems existing in the prior art. For this reason, this application proposes a control method for an air purifier and an air purifier, so that users can directly experience the purification effect of the air purifier and improve the user experience.

[0004] An embodiment of one aspect of this application provides a control method for an air purifier.

The control method includes: acquiring the working mode of the air purifier, the working mode including a standby mode; when the air purifier is in standby mode, turning on the cleaning device to remove dust particles from the filter element.

[0016] Furthermore, the cleaning device includes an air outlet, and turning on the cleaning device includes: controlling the air outlet to rotate to change the relative angle between the air outlet and the filter element, and spraying compressed air onto the filter element through the air outlet.

[0017] Furthermore, before the step of turning on the cleaning device, the process includes: obtaining the airflow rate of the air outlet; when the airflow rate is less than a set airflow rate threshold, the air purifier starts a standby mode and then starts the cleaning device.

[0018] An air purifier provided in another embodiment of this application includes at least one processor and a memory for communicatively connecting to the processor; the memory stores instructions executable by the processor, which, when executed by the processor, enable the processor to perform the air purifier control method as described above.

[0029] In the air purifier control method and air purifier provided in this application embodiment, by controlling the first light source to turn on in purification mode, the first light source illuminates the air entering the first chamber, which can induce the Tyndall effect in the first chamber. This allows the user to observe dust particles in the air that has not been filtered by the purifier body, thus enabling the user to intuitively perceive the degree of air pollution and increasing the desire to use the air purifier. As the air purifier operates, the dust particles in the bright passage gradually decrease, thus allowing the user to intuitively experience the purification effect of the air purifier. In this application embodiment, the first light source is located in the first chamber. When the purifier body is working, the airflow velocity and direction in the first chamber are less affected by interference or fluctuations compared to the outside of the air purifier, which is conducive to the formation of the Tyndall effect and helps to optimize the user experience.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] See Figure 1 As shown, one embodiment of this application discloses an air purifier that utilizes the Tyndall effect to allow users to intuitively observe the dust particles in the air that has not been purified by the air purifier, thereby visualizing the purification effect and increasing users' desire to use the air purifier.

[0042] like Figure 1 An air purifier disclosed in one embodiment of this application includes a purifier body, a first light source 200, a light sensor 310, and a control component.

[0043] Specifically, the air purifier body includes a housing 110, which has an air inlet 111 and a first chamber 112, with the air inlet 111 and the first chamber 112 in fluid communication. A first light source 200 is disposed in the first chamber 112, with the incident direction of the first light source 200 intersecting the extension direction of the air inlet 111. The first light source 200 is a variable light source. A light sensor 310 is used to acquire the ambient light intensity of the air purifier. A control component is connected to the light sensor 310 and the first light source 200, and is used to control the light intensity of the first light source 200 according to the ambient light intensity. The housing 110 is provided with a light-transmitting area 113, which is used for the user to observe the area illuminated by the first light source 200.

[0044] In the air purifier provided in this embodiment, the housing 110 is provided with an air inlet 111 and a first chamber 112. A first light source 200 is provided in the first chamber 112, and the light beam emitted by the first light source 200 can illuminate the air flowing into the first chamber 112 from the air inlet 111. When the light beam emitted by the first light source 200 illuminates the air flowing into the first chamber 112, a bright path can be formed in the incident direction of the first light source 200, that is, the Tyndall effect is generated in the first chamber 112, making the dust particles in the path visible; at the same time, the housing 110 is provided with a light-transmitting area 113, which allows the user to observe the Tyndall effect in the first chamber 112.

[0045] This allows users to observe dust particles in the air that has not been filtered by the purifier itself, enabling them to intuitively perceive the level of air pollution and thus increasing their desire to use an air purifier. As the air purifier operates, the dust particles in the bright passage gradually decrease, allowing users to directly experience the purification effect of the air purifier.

[0046] In this embodiment, the control component includes a processor for controlling the first light source 200 and other components.

[0047] In this embodiment, the first light source 200 is disposed in the first chamber 112. When the purifier body is working, the air velocity and direction in the first chamber 112 are less affected by interference or fluctuations compared to the outside of the air purifier, which is conducive to the formation of the Tyndall effect and helps to optimize the user experience.

[0048] In this embodiment, see Figure 1 The extension direction of the air inlet 111 is a, and the incident direction of the first light source 200 is b. The incident direction of the first light source 200 intersects with the extension direction of the air inlet 111, so that the first light source 200 can irradiate the air flowing into the first chamber 112 from the outside.

[0049] Furthermore, as the air purifier is turned on and continues to operate, the amount of dust particles observed by the user in the light-transmitting area 113 gradually decreases, and the Tyndall effect no longer forms in the first chamber 112. In other words, by comparing the dust particles in the first chamber 112 before and after the Tyndall effect, the user can intuitively perceive the purification effect of the air purifier.

[0050] It is understandable that the incident direction of the first light source 200 can be set according to factors such as the user's observation angle, the extension direction of the air inlet 111, and the airflow direction in the first chamber 112.

[0051] Once the Tyndall effect is established within the first chamber 112, a bright "path" can be observed when viewed from an incident direction perpendicular to the first light source 200. The aerosol particles displayed in this "path" are dust particles from the air. Thus, users can directly observe dust particles in the air.

[0052] In some embodiments of this application, see Figure 1 The incident direction of the first light source 200 is perpendicular to the extension direction of the air inlet 111. When the incident direction of the first light source 200 is perpendicular to the extension direction of the air inlet 111, the first light source 200 can be incident perpendicularly into the air flowing into the first chamber 112 from the air inlet 111, making the interaction between the light and the colloidal particles more complete, and the intensity of the scattered light reaches its maximum in the vertical direction, which can clearly form a bright light path, thus facilitating user observation and identification.

[0053] It is worth noting that in some other embodiments, the incident direction of the first light source 200 may also be set at a certain angle to the air inlet 111. That is, the light beam emitted by the first light source 200 is incident obliquely into the air flowing into the first chamber 112 from the air inlet 111, which can create a unique visual effect in that part of the air.

[0054] It should be noted that in the above embodiments, the incident angle of the first light source 200 can be set to 45°, 60° or other angles according to the visual effect requirements.

[0055] In this embodiment, the light-transmitting area 113 can specifically be a notch provided on the housing 110, or a light-transmitting structure formed by a light-transmitting material provided in the notch area of ​​the housing 110; of course, the light-transmitting area 113 can also be the area of ​​the transparent housing 110 corresponding to the first chamber 112. In this way, the user can easily observe the bright "pathway" formed in the first chamber 112, i.e., the Tyndall effect, from the light-transmitting area 113.

[0056] In some embodiments of this application, the light-transmitting area 113 is provided with a light-transmitting element. Specifically, the light-transmitting element is a structure made of a transparent material. Exemplarily, the light-transmitting element may be made of glass, acrylic, or transparent plastic.

[0057] In some other embodiments of this application, the light-transmitting element includes one-way transparent glass. Specifically, the housing 110 has a notch on the side corresponding to the first light source 200, and one-way transparent glass is installed in this notch. Light from outside the air purifier cannot pass through this one-way glass to reach the first chamber 112, while light from inside the first chamber 112 can pass through the one-way glass to reach the outside of the air purifier, allowing the user to observe the Tyndall effect formed inside the first chamber 112. In this embodiment, by providing one-way transparent glass, the probability of light from outside the air purifier reaching the first chamber 112 and causing interference or weakening of the Tyndall effect inside the first chamber 112 can be reduced.

[0058] Of course, in other possible implementations, the light-transmitting element can be one-way transparent glass, and more specifically, one-way transparent photochromic glass. The mirror surface of the one-way transparent glass is positioned facing the inside of the first chamber 112, allowing the user to observe the Tyndall effect inside the first chamber 112 from outside the air purifier.

[0059] In some other embodiments of this application, the light-transmitting element includes a transparent plastic element. Light from outside the air purifier can pass through the light-transmitting element into the first chamber 112, and light from inside the first chamber 112 can also pass through the transparent plastic element.

[0060] In some other embodiments, the light-transmitting area 113 may be a notch located on the housing 110, and a portion of the air inlet 111 may be located on this notch. That is, a portion of the air inlet 111 and the light-transmitting area 113 are located at the same position on the housing 110.

[0061] In this embodiment, at least a portion of the housing 110 is made of transparent plastic, transparent glass, or one-way transparent glass, so that the Tyndall effect formed in the first chamber 112 can be observed by a user located on one side of the air purifier.

[0062] The Tyndall effect is affected by the incident angle of the light source, the background color, the light path, the light intensity, and the ambient light intensity. In order to achieve a more ideal observation effect, the background color is required to be dark. The background color of this solution is black, the light path is vertical or vertical multi-angle reflection, and the light intensity of the light source is fixed or adjustable. This solution adopts adjustable light intensity.

[0063] It is understandable that the background color within the first chamber 112 will affect the observation effect when observing the Tyndall effect. In some embodiments of this application, a background wall is formed within the first chamber 112, located on the side of the irradiated area away from the light-transmitting area 113, and the surface color of the background wall is set to a dark color. This facilitates user observation of the Tyndall effect generated within the first chamber 112, thus improving the user experience.

[0064] It should be noted that the background wall can be a separate component located behind the user's line of sight, or it can be formed on the inner wall of the first chamber 112. The first chamber 112 is defined by the inner wall of the housing 110 and the surfaces of the various components disposed within the first chamber 112. In this case, the background wall can be formed on one or more of the inner wall of the housing 110 and the outer surfaces of the various components located within the first chamber 112. For example, the purifier body includes a filter assembly, the outer surface of which is located within the first chamber 112 and at least partially within the user's observation range. The portion of the filter assembly observed by the user is set to a dark color.

[0065] It is worth understanding that dark colors refer to colors with low brightness. For example, dark colors include, but are not limited to, black, dark gray, dark red, dark purple, and dark blue. In this way, the background wall can increase the contrast with the light generated in the first chamber 112, thereby making it easier for users to intuitively observe the dust particles in the light path.

[0066] The control component is connected to the light sensor 310 and the first light source 200. The light sensor 310 is used to detect the light intensity outside the housing 110. In this way, the control component can adjust the light intensity of the first light source 200 according to the external light intensity obtained by the light sensor 310, so that the light intensity of the first light source 200 is always higher than the light intensity of the ambient light, thereby ensuring that the Tyndall effect is always generated in the first chamber 112.

[0067] In some embodiments of this application, see Figure 1 The purifier body includes a filter assembly disposed within a first chamber 112, with a gap between the filter assembly and the air inlet 111. A first light source 200 is located between the air inlet 111 and the filter assembly in the housing 110. Thus, when outside air flows into the first chamber 112 from the air inlet 111, it is first irradiated by the first light source 200, generating the Tyndall effect, before being filtered and purified by the filter assembly. Because the space through which the light passes is narrow, the dust concentration per unit volume is higher, making the Tyndall effect more pronounced.

[0068] In one possible implementation, the filter assembly includes a filter element 121 disposed within a first chamber 112, with a gap between the filter element 121 and the air inlet 111.

[0069] It should be understood that the first light source 200 can be positioned anywhere within the gap between the air inlet 111 and the filter element 121, and is not limited to the line connecting the air inlet 111 and the filter element 121. For example, the first light source 200 may be positioned diagonally above the air inlet 111, such as... Figure 1 As shown.

[0070] It should be noted that in some other possible implementations, the filter element 121 may be located outside the first chamber 112, so that the first chamber 112 serves as a display space for the formation of the Tyndall effect.

[0071] In some embodiments of this application, see Figure 1 The filter assembly includes a filter element 121, which is disposed within the first chamber 112. The purifier body includes a cleaning device 130, which is used to remove dust particles from the filter element 121. By removing residual dust particles from the air filtered by the filter element 121 using the cleaning device 130, the filtration and purification effect can be guaranteed, thereby extending the service life of the filter element 121 and reducing operating costs.

[0072] In one possible implementation, see Figure 1The cleaning device 130 has an air outlet 131 facing the filter element 121. The cleaning device 130 blows air into the filter element 121 through the air outlet 131. Dust particles in the filter element 121 are reversed by the airflow, causing them to move in the opposite direction to the purified airflow, thereby detaching the dust particles from the filter element 121. In this embodiment, the cleaning device 130 includes a compression mechanism for generating compressed air and blowing it from the air outlet 131 towards the filter element 121 to clean the filter element 121.

[0073] In some embodiments of this application, see Figure 1 The cleaning device 130 includes a dust collection box 140, which is disposed on one side of the filter element 121 and is used to collect dust particles that fall off the filter element 121.

[0074] Furthermore, the dust collection box 140 is made of a transparent material.

[0075] In some embodiments of this application, please refer to... Figure 1 The air purifier includes a second light source 400, and the housing 110 has a second chamber 114 and an air outlet. The second light source 400 is disposed within the second chamber 114. Specifically, the air purified by the purifier body first flows through the second chamber 114, and then is discharged back to the outside of the air purifier through the air outlet. The light beam emitted by the second light source 400 can illuminate the air inside the second chamber 114. When there are many dust particles in the air inside the second chamber 114, the Tyndall effect can occur; when the dust particles in the air inside the second chamber 114 decrease or even become zero, the Tyndall effect weakens or even fails to occur. Thus, the purification effect of the air purifier can be visually observed by whether the Tyndall effect occurs in the air inside the second chamber 114 and the strength of the Tyndall effect.

[0076] In the above embodiment, the housing 110 is provided with an observation window for the user to observe the air quality in the second chamber 114.

[0077] In some embodiments of this application, a filter assembly and a cleaning device 130 are also included. The filter assembly includes a filter element 121, which is disposed in a first chamber 112. A first light source 200 is located between an air inlet 111 and the filter element 121. The cleaning device 130 is used to remove dust particles from the filter element 121.

[0078] In some embodiments of this application, the wavelength of the first light source 200 is 400nm to 700nm. When the wavelength of the first light source 200 is chosen to be 400-700nm, and the light beam passes through a colloid with particle diameters of 1-100nm, a bright "pathway" can be seen in the colloid when viewed from a direction perpendicular to the incident light. This "pathway" is formed because the sol particles are generally no more than 100nm, which is smaller than the visible light wavelength (400-700nm), thus generating the Tyndall effect when visible light passes through the sol.

[0079] It is understandable that the wavelength of the first light source 200 can be selected as 500nm, 600nm, or 700nm, depending on the actual display effect requirements.

[0080] See Figure 1 and Figure 2 Another embodiment of this application discloses a control method for an air purifier. The air purifier includes a purifier body and a first light source 200. The purifier body has an air inlet 111 and a first chamber 112. The air inlet 111 and the first chamber 112 are in fluid communication. The first light source 200 is disposed in the first chamber 112. The incident direction of the first light source 200 intersects the extending direction of the air inlet 111. The control method includes the following steps:

[0081] S110: Obtain the working mode of the air purifier, including the purification mode;

[0082] S120: When the air purifier is in purification mode, turn on the first light source 200.

[0083] In the above embodiment, in purification mode, the air purifier begins to purify the air, meaning that the air purifier can draw outside air into the first chamber 112 through the air inlet 111. During this process, the first light source 200 is turned on, so that the light beam emitted by the first light source 200 illuminates the air flowing into the first chamber 112. When the light beam emitted by the first light source 200 illuminates the air flowing into the first chamber 112, a bright path can be formed in the incident direction of the first light source 200, that is, the Tyndall effect is generated in the first chamber 112, which makes the dust particles in the path visible; at the same time, the housing 110 is provided with a light-transmitting area 113, which allows the user to observe the Tyndall effect in the first chamber 112.

[0084] This allows users to visually observe dust particles in the air that has not been filtered by the air purifier itself, enabling them to directly perceive the level of air pollution and thus increasing their desire to use the air purifier. As the air purifier operates, the dust particles in the bright passageway gradually decrease, allowing users to directly experience the purification effect of the air purifier.

[0085] The first light source 200 is used to create the Tyndall effect within the first chamber 112, forming a bright path in the air within the first chamber 112, thus allowing the user to visually observe the dust particles in the air. In other words, the first light source 200 is used to show the user the air quality before purification, and the first light source 200 can remain off when the user is not around the air purifier.

[0086] In this embodiment, see Figure 3 When the air purifier is in purification mode, the first light source 200 is turned on, including:

[0087] S121: Obtain the user's location and determine the initial distance between the user and the air purifier based on the user's location;

[0088] S122: When the first distance is less than the preset first distance threshold, control the first light source 200 to turn on.

[0089] In this way, the first light source 200 can be turned on when the user approaches the air purifier and turned off when the user moves away from the air purifier.

[0090] It is understandable that the preset first distance threshold can be set according to factors such as the size of the space where the air purifier is located, the spatial layout, and the user's visual distance to observe the first chamber 112.

[0091] In one possible implementation, the air purifier includes a human body detection sensor mounted on the housing 110. The human body detection sensor acquires the location of the user around the air purifier to facilitate the calculation of a first distance between the user and the air purifier.

[0092] In some embodiments of this application, when the air purifier is in purification mode, the step of turning on the first light source 200 includes reducing the airflow velocity at the air inlet 111. Thus, when a user approaches the air purifier, reducing the airflow velocity at the air inlet 111 facilitates observation of the Tyndall effect, helping the user to clearly observe dust particles in the bright path formed by the Tyndall effect.

[0093] It is understandable that the step of reducing the airflow speed at the air inlet 111 can be performed before the first light source 200 is turned on, after the first light source 200 is turned on, or simultaneously with the turning on of the first light source 200; no limitation is made here.

[0094] In some embodiments of this application, see Figure 4 The step of activating the first light source 200 includes:

[0095] S124: Obtain the ambient light intensity of the air purifier;

[0096] S126: Adjust the light intensity of the first light source 200 according to the ambient light intensity so that the light intensity of the first light source 200 is greater than the ambient light intensity.

[0097] This ensures the brightness of the Tyndall effect, allowing users to clearly observe dust particles in the air within the first chamber 112 and thus intuitively perceive the air quality.

[0098] In some embodiments of this application, the air purifier includes an ambient light, which is mounted on the housing 110 of the air purifier body. The ambient light is used to generate ambient light so that the user can easily observe the irradiated area of ​​the first light source 200.

[0099] In one possible implementation of this application, see [link to relevant documentation]. Figure 1 The air purifier body includes a housing 110 and a filter element 121. The housing 110 has an air inlet 111 and a first chamber 112. The filter element 121 is disposed within the first chamber 112, and a first light source 200 is disposed between the air inlet 111 and the filter element 121. The housing 110 has a light-transmitting area 113, which is specifically constructed of ordinary glass or transparent plastic. When a user approaches the air purifier, the first light source 200 is activated, and the airflow speed at the air inlet 111 is reduced to facilitate observation of the Tyndall effect within the first chamber 112, allowing for direct observation of airborne particulate matter. In this design, the light intensity of the first light source 200 can be greater than, equal to, or less than, the ambient light intensity. Typically, the Tyndall effect is more pronounced within the first chamber 112 when the light intensity of the first light source 200 is greater than the ambient light intensity.

[0100] In some other possible implementations, the light-transmitting zone 113 is made of one-way transparent glass or one-way viewing glass. In application, the luminous intensity of the first light source 200 should be controlled so that the light intensity inside the first chamber 112 is greater than the light intensity outside the first chamber 112, so that the user can always observe the Tyndall effect inside the first chamber 112. It is worth understanding that the light intensity outside the first chamber 112 is determined by the ambient light intensity and the ambient light intensity of the space where the air purifier is located.

[0101] In some embodiments of this application, the step of turning on the first light source 200 when the air purifier is in purification mode includes:

[0102] Obtain the user's location and determine the second distance between the user and the air purifier based on the user's location;

[0103] When the second distance is less than the preset second distance threshold, the ambient light is turned on.

[0104] In the above embodiments, when the first light source 200 is turned on, the ambient light is turned on, which can provide contrasting ambient light, so that the Tyndall effect in the first chamber 112 can be better presented in front of the user's field of vision, which is conducive to improving the user experience.

[0105] The specific value of the second distance threshold can be set according to the actual order of light activation and trigger distance. Specifically, the second distance threshold can be the same as the first distance threshold, or it can be greater than or less than the first distance threshold.

[0106] For example, if the second distance threshold is greater than the first distance threshold, then when the user approaches the air purifier, the ambient light turns on first, and then the first light source 200 is turned on.

[0107] In some embodiments of this application, see Figure 1 The air purifier includes a second chamber 114 and a second light source 400, the second light source 400 being disposed in the second chamber 114. The control method includes: acquiring the operating mode of the air purifier; and turning on the second light source 400 when the air purifier is in purification mode.

[0108] Specifically, the housing 110 also has an air outlet communicating with the second chamber 114. The air purified by the purifier body first flows through the second chamber 114 and then is discharged back to the outside of the air purifier through the air outlet. The light beam emitted by the second light source 400 can illuminate the air inside the second chamber 114. When there are many dust particles in the air inside the second chamber 114, the Tyndall effect can occur; when the dust particles in the air inside the second chamber 114 decrease or even become zero, the Tyndall effect weakens or even fails to occur. Thus, by observing whether the Tyndall effect occurs in the air inside the second chamber 114 and the strength of the Tyndall effect, the purification effect of the air purifier can be visually observed.

[0109] In the above embodiment, the housing 110 is provided with an observation window for the user to observe the air quality in the second chamber 114.

[0110] In some embodiments of this application, the air purifier includes a display screen, and the control method includes: acquiring and analyzing images of the air purified by the air purifier to determine the concentration of particulate matter in the purified air; and displaying the particulate matter concentration value on the display screen. Thus, the purified air quality can be displayed on the display screen, allowing users to accurately perceive the purification effect of the air purifier.

[0111] The specific location of the display screen can be set according to the actual situation to facilitate user observation of the display screen.

[0112] In some embodiments of this application, the air purifier includes an alarm, and the control method includes: when the concentration of dust particles is greater than a preset concentration threshold, activating the alarm and triggering an alarm to alert the user.

[0113] In one possible implementation, when the concentration of dust particles exceeds a preset concentration threshold, the alarm is triggered, prompting the user to turn on the air purifier to purify the indoor air.

[0114] Furthermore, when the alarm sounds, the air purifier is controlled to increase its purification level, thereby enhancing its ability to purify the air.

[0115] In one possible implementation, when the alarm sounds, the air purifier is switched to standby mode, and then the cleaning device 130 is activated to clean the filter element 121. If the alarm remains active after cleaning, the user is prompted to replace the filter element 121.

[0116] In some embodiments of this application, see Figure 1 The air purifier body includes a filter element and a cleaning device 130. The filter element is disposed in the first chamber 112, and the cleaning device is used to remove dust particles from the filter element. The control method includes: acquiring the operating mode of the air purifier, including a standby mode; when the air purifier is in standby mode, activating the cleaning device 130 to remove dust particles from the filter element 121. In this way, the cleaning device can be controlled to clean the filter element 121, thereby ensuring the purification effect.

[0117] In one possible implementation, see Figure 1 The cleaning device 130 includes an air outlet 131. Activating the cleaning device 130 involves controlling the air outlet 131 to rotate, thereby changing the relative angle between the air outlet and the filter element, and spraying compressed air onto the filter element 121 through the air outlet 131. The direction of the compressed air flow is opposite to the airflow direction at the air inlet 111 in the purification mode. Thus, by controlling the compressed air to be blown out from the air outlet 131, dust particles on the filter element 121 can be blown away in the opposite direction and detached from the filter element 121, thereby cleaning the filter element 121. The blowing angle of the air outlet 131 is variable. Therefore, when cleaning the filter element 121, by controlling the angle between the air outlet 131 and the filter element 121, the sweeping area of ​​the air outlet 131 can be increased, thereby expanding the cleaning area.

[0118] In addition, before cleaning the filter element 121, the filter element 121 can be divided into sections. First, the amount of dust particles in each section of the filter element 121 can be obtained, and then the blowing angle and residence time of the air outlet 131 can be determined to ensure the cleaning effect.

[0119] In some embodiments of this application, before activating the cleaning device 130, the following steps are included: obtaining the airflow rate at the air outlet; when the airflow rate is less than a set airflow rate threshold, the air purifier enters standby mode and the cleaning device 130 is activated. The cleanliness of the filter element 121 can be determined based on the airflow rate at the air outlet. Specifically, as the amount of dust particles accumulated on the filter element 121 increases, the airflow rate at the air outlet decreases. When the airflow rate is lower than a preset airflow rate threshold and the air purifier is in standby mode, the cleaning device 130 is activated to clean the filter element 121.

[0120] In the above embodiments, the airflow rate threshold is used as the comparison object for airflow rate, and its type corresponds to the type of airflow rate. Its value can be determined according to the actual situation. Generally, if the airflow rate is greater than the airflow rate threshold, it indicates that there are fewer dust particles in the filter element 121 and the current filter element is relatively clean; if the airflow rate is less than the airflow rate threshold, it indicates that there are more dust particles in the filter element 121 and the current filter element 121 needs to be cleaned.

[0121] It's worth noting that standby mode refers to the air purifier being in non-purification mode, where it is not purifying the air. Therefore, cleaning the air purifier's filter 121 in standby mode avoids affecting the air quality outside the air purifier during the cleaning process.
