[0047] With the accelerating pace of modern life and the increasing prominence of environmental pollution, people's demands for indoor air quality are gradually increasing. Today, air purifiers have become an indispensable part of many homes and offices. Especially in large cities, the frequent occurrence of environmental issues such as smog and renovation pollution has led to a significant increase in consumer demand for air purifiers. Growing awareness of health and environmental protection has prompted people to pay more attention to the air quality in their homes, especially for families with elderly people, children, or those with allergies. Air purifiers can effectively remove indoor allergens such as fine particulate matter, pollen, dust mites, and pet hair. However, the use of these devices in the home remains limited, with younger and older users having difficulty using complex home appliances. This results in the need for user-specific adjustments to the operation of air purifiers.

[0048] Therefore, reference Figure 1 The present invention provides a control method for an air purifier, wherein the air purifier includes a control device, a touch display device, a voice pickup device, and an image pickup device; the control device is connected to the touch display device, the voice pickup device, and the image pickup device respectively; the control method includes:

[0049] Step S100: generating a first matching result between the voice signal and a preset voice signal in response to the voice signal output by the voice pickup device;

[0050] Step S200: generating a second matching result between the picture signal and a preset picture signal in response to the picture signal output by the picture pickup device;

[0051] Step S300: Based on the first matching result and the second matching result, when the voice signal matches the pre-stored voice signal and the picture signal matches the pre-stored picture signal, confirm the user's identity information and control the touch display device to display the corresponding preset operation interface.

[0052] In this embodiment, the voice pickup device can be implemented using multiple condenser microphones, multiple dynamic microphones, or multiple electret microphones. The voice pickup device can pick up sound signals within a preset area of the air purifier and convert them into corresponding electrical signals to output to the control device. For example, when the air purifier is placed in a certain area of the home, under the condition that the air purifier is turned on, the voice signal output by the user is received, and the received voice signal is matched with the preset voice signal to obtain a first matching result. It can be understood that by presetting the corresponding voice signal in the control device, the corresponding action can be performed under the condition that the air purifier receives the corresponding voice signal. For example, when the user outputs a voice signal indicating the start of air purification, the air purifier receives the voice signal through the voice pickup device, and the control device matches the electrical signal output by the voice pickup device with the preset voice signal pre-stored in the control device to obtain a first matching result, thereby executing the action of starting air purification. In addition, the control device can also confirm the identity of the user corresponding to the received voice signal through the voiceprint of the pre-stored preset voice signal. For example, when the voice pickup device in the air purifier picks up a pre-stored preset voice signal in a preset area, the air purifier can preliminarily confirm the user who may currently need to use the air purifier, and adjust the screen displayed by the touch display device to the preset screen for the corresponding user's use.

[0053] In this embodiment, the air purifier may be located in a noisy environment. This noise may come from the operation of the air purifier's own fan or from the surrounding environment. It is understood that noise may cause errors in the voice signal output by the air purifier's voice pickup device, leading to erroneous matching results or even failure of voice matching. Therefore, in this embodiment, an image pickup device is provided in the air purifier to capture image signals within a preset range of the air purifier. It is understood that to ensure that the air purifier can effectively capture image signals centered on itself, multiple image pickup devices are required. The image pickup devices can be implemented as network cameras, surveillance cameras, and the like. The control device compares the image signal output by the image pickup device with a pre-stored preset image signal to determine whether the image signal received by the image pickup device matches the pre-stored preset image signal, and then outputs a second matching result. The preset image signal can be pre-recorded and stored, or automatically identified using a corresponding algorithm. Furthermore, the air purifier can also use the image pickup device to capture image signals within a preset range, thereby confirming environmental characteristics within the preset range and, therefore, determining the area within which movement is permitted. The preset range here is the range within which the image pickup device can capture images.

[0054] In this embodiment, the control device can generate a first matching result between the voice signal and the preset voice signal through the voice signal output by the voice pickup device, and can also generate a second matching result between the picture signal and the preset picture signal through the picture signal output by the picture pickup device. In order to avoid an error in the matching result obtained by the signal output by any of the pickup devices, the control device will confirm whether the first matching result and the second matching result are both matched, thereby confirming the user's identity information when the first matching result and the second matching result are both matched. For example, if the first matching result between the voice signal output by the voice pickup device and the preset voice signal is the identity information of the first user, and the second matching result between the picture signal output by the picture pickup device and the preset picture signal is the identity information of the second user, it can be confirmed that there is an erroneous recognition, and the control device will not control the touch display device to display the corresponding preset operation interface to avoid erroneous judgment.

[0055] A control method for an air purifier is adopted to effectively improve the adaptability of the air purifier. The air purifier includes a control device, a touch display device, a voice pickup device, and a picture pickup device; the control device is connected to the touch display device, the voice pickup device, and the picture pickup device, respectively. In response to a voice signal output by the voice pickup device, a first matching result between the voice signal and a preset voice signal is generated. In response to a picture signal output by the picture pickup device, a second matching result between the picture signal and a preset picture signal is generated. The preset voice signal and the preset picture signal can be stored in the control device by preset entry, or the user's identity information can be automatically identified by a specific algorithm. Based on the first matching result and the second matching result, if the voice signal matches the pre-stored voice signal and the picture signal matches the pre-stored picture signal, the user's identity information is confirmed, and the touch display device is controlled to display the corresponding preset operation interface, thereby meeting the operation interface needs of different groups of people.

[0056] In one embodiment of the present invention, the air purifier further includes a fan connected to the control device; before the step of responding to the voice signal output by the voice pickup device, the control method includes:

[0057] In response to the voice wake-up signal acquired by the voice pickup device, the operating power of the fan is controlled to be reduced to a corresponding preset power, so that the voice pickup device can accurately acquire the voice signal.

[0058] It is understandable that the air purifier needs to circulate and purify the indoor air by controlling the operation of the fan. The fan inside the air purifier generates airflow and draws the indoor air into the purifier. In this process, the air will pass through a series of filter layers or other purification technologies to remove particulate matter, harmful gases and other pollutants in the air. Among them, when the air purifier is in normal operation, the control device will drive the fan to work through the corresponding drive device. When the fan is working at high power, the noise generated by it may cause noise in the voice content picked up by the voice pickup device, thereby causing the voice signal to not correspond to the preset voice signal. Therefore, in this embodiment, the control device can obtain a voice wake-up signal through the voice pickup device, thereby controlling the working power of the fan to drop to the preset power, thereby reducing the noise generated by the fan operation, so that the voice pickup device can more accurately obtain and output the voice signal within the preset range. Among them, the voice wake-up signal can be implemented using an easily recognizable voice signal.

[0059] In one embodiment of the present invention, after the step of responding to the voice signal output by the voice pickup device, the control method includes:

[0060] In a case where the voice signal corresponds to a preset voice control signal, the operating power of the fan is adjusted to a preset power corresponding to the preset voice control signal.

[0061] In this embodiment, the control device can achieve contactless control of the operation of the air purifier by pre-storing a matching relationship between a corresponding preset voice control signal and a voice signal output by the voice pickup device. There are multiple groups of pre-stored preset voice control signals, each corresponding to a different preset power of the fan. For example, when the voice pickup group receives the corresponding voice information and outputs a voice signal corresponding to the first preset voice control signal, the control device controls the fan to operate at the first preset power; when the voice pickup group receives the corresponding voice information and outputs a voice signal corresponding to the second preset voice control signal, the control device controls the fan to operate at the second preset power. The preset power can be 0, that is, the preset voice control signal corresponding to the voice signal output by the voice pickup device is to control the fan to stop operating.

[0062] refer to Figure 2 In one embodiment of the present invention, the step of confirming the user's identity information and controlling the touch display device to display the corresponding preset operation interface includes:

[0063] Step S310: When the user's identity information is confirmed to be in the first age status, controlling the touch display device to display a first preset operation interface;

[0064] Step S320: When the user's identity information is confirmed to be in the second age status, controlling the touch display device to display a second preset operation interface;

[0065] Step S330: When the user's identity information is confirmed to be the third age status, control the touch display device to display a third preset operation interface.

[0066] There are certain differences in the physical functions and control cognition of users of different age groups. For example, for children, the operation interface they need needs to be simple and easy to understand, with high screen recognition; for adults, they have stronger cognitive abilities, so more complex functions can be set in the operation interface, such as the redemption of points earned from the use of the air purifier; and for the elderly, their ability to accept technological updates and their eyesight may decline, so the operation interface needs to be simple and the font size is enlarged. It can be understood that by confirming the user's identity information and then controlling the touch display device to display different preset operation interfaces, the actual needs of users of different age groups in using the air purifier can be effectively met. In this embodiment, the user's identity information is divided into three age states, and the operation interface that can be displayed by the touch display device is divided into three preset operation interfaces. The user's identity information is confirmed through the first matching result and the second matching result. Among them, the preset voice signal and the preset screen signal can both be pre-stored related information.

[0067] In one embodiment of the present invention, after the touch display device displays the corresponding preset operation interface, the method includes:

[0068] Based on the touch signal received by the touch display device in the preset operation interface, the air purifier is controlled to execute the corresponding working mode.

[0069] In this embodiment, the touch display device includes a touch device and a display device. The touch device can be implemented by any one of a resistive touch screen, a capacitive touch screen, a surface acoustic wave touch screen, etc.; the display device can be implemented by a liquid crystal display device, an organic light-emitting diode, etc. By electrically connecting the touch device and the display device in the touch display device to the control device respectively, the display device can display a preset operation interface when receiving a display control signal output by the control device, and when the touch device is triggered, it outputs a corresponding touch signal to the control device, so that the control device outputs a corresponding control signal to the corresponding device, thereby achieving the technical effect of controlling the air purifier to execute the corresponding operating mode.

[0070] refer to Figure 3In one embodiment of the present invention, the air purifier further includes an air quality detection device and a mobile device, and the control device is connected to the air quality detection device and the mobile device respectively; the method for controlling the air purifier to execute a corresponding operating mode based on a touch signal received by the touch display device in the preset operation interface includes:

[0071] Step S340: When the touch display device receives an adaptive touch signal in the preset operation interface, controlling the air purifier to execute an adaptive working mode;

[0072] Step S350: When the working mode of the air purifier is the adaptive working mode, the mobile device is controlled to move toward a specific area based on the air quality detection signal output by the air quality detection device and the image signal output by the image pickup device.

[0073] In this embodiment, the air quality detection device can be implemented by one or more of a particle concentration detection sensor, a VOC gas sensor, a carbon dioxide sensor, etc. The mobile device can be implemented by a motor, a roller, etc. It is understandable that the air purifier can only stably purify the air within a certain area where it is located, and cannot effectively purify the air outside the area. Therefore, in order to ensure that the air purifier achieves comprehensive and efficient air purification in a specific area, an adaptive working mode is provided in the air purifier. Among them, the adaptive working mode of the air purifier is executed when the touch display device receives an adaptive touch signal under the preset operation interface by the control device. At this time, the control device will judge the air purification situation in the area where the air purifier is located based on the air quality detection signal output by the air quality detection device, and then confirm whether it is necessary to move the air purifier by the mobile device to achieve efficient air purification in the specific area.

[0074] refer to Figure 4 Optionally, there are multiple air quality detection devices, and the multiple air quality detection devices are respectively arranged on multiple sides of the air purifier; there are multiple image pickup devices, and they are arranged corresponding to the air quality detection devices; the method of controlling the mobile device to move toward a specific area based on the air quality detection signal output by the air quality detection device and the image signal output by the image pickup device includes:

[0075] Step S351: confirming the air quality of each side of the air purifier based on the air quality detection signals output by the multiple air quality detection devices;

[0076] Step S352: confirming the movable area of each side of the air purifier based on the image signals output by the plurality of image pickup devices;

[0077] Step S353: performing a gradient comparison on the air quality at each side of the plurality of air purifiers to determine a priority purification area;

[0078] Step S354: When the priority purification area and the movable area are confirmed, control the mobile device to move toward a specific area.

[0079] In this embodiment, multiple air quality detection devices are provided, each located on different sides of the air purifier. The devices output multiple air quality detection signals to the control device, allowing the control device to determine the air quality on different sides of the air purifier. For example, four air quality detection devices are provided, each located on one side of the air purifier. The control device receives the four air quality detection signals and, by evaluating them, determines the air quality on each of the four sides of the air purifier, thereby determining the direction of the area to be purified by the air purifier in the next stage. Furthermore, multiple image pickup devices are provided, each corresponding to the air quality detection devices, i.e., corresponding to the side of the air purifier where the air quality detection device is located. The control device is electrically connected to the multiple image pickup devices to capture image signals from multiple sides of the air purifier, thereby determining the direction in which the air purifier can move. It is understood that the control device performs a gradient comparison of the air quality detection signals output by the multiple air quality detection devices to determine the air quality on each side of the air purifier and thereby determine the priority purification area. It is understood that the priority purification area is the side with the worst air quality among the multiple sides of the air purifier. At this time, the control device will control the mobile device to move toward the specific area after confirming the priority purification area and the movable area, thereby achieving the technical effect of adaptively adjusting the purification area.

[0080] Optionally, the method of controlling the mobile device to move toward a specific area when the priority purification area and the movable area are confirmed includes:

[0081] When there is a correspondence between the priority purification area and the movable area, controlling the moving device to move toward the priority purification area;

[0082] If there is no correspondence between the priority purification area and the movable area, a secondary purification area is identified, and if there is a correspondence between the secondary purification area and the movable area, the moving device is controlled to move toward the secondary purification area.

[0083] In this embodiment, it is necessary to consider whether the priority purification area is a movable area. For example, if there is an obstacle in the priority purification area that prevents the air purifier from moving to this area, that is, the control device confirms the presence of an obstacle on the side of the air purifier through the image signal. At this time, the control device performs a gradient comparison on the air quality detection signals output by multiple air quality detection devices to confirm the air quality of each side of the air purifier, and then confirms the secondary purification area, that is, the priority purification area, which is the side with the second worst air quality among the multiple sides of the air purifier. The control device further controls the mobile device to move toward the secondary purification area by judging whether there is an obstacle in the corresponding image signal.

[0084] The present invention also provides a control device, comprising: a memory, a processor, and an air purifier control program stored in the memory and running on the processor, wherein the air purifier control program is configured to implement the steps of any of the above-described air purifier control methods.
