Technical Field

[0001] This application relates to the field of intelligent control technology, and in particular to a purification device, a purification device control method, an apparatus, a computer device, a storage medium, and a computer program product. Background Technology

[0002] With the gradual improvement of people's living standards and the increasing severity of environmental problems, air purification equipment has become a best-selling household appliance. Air purification equipment generally uses filters installed inside the device to effectively adsorb pollutants such as dust, odors, and impurities in the air, thereby achieving the goal of providing clean, high-quality air for the indoor environment.

[0003] The filter in an air purifier can be considered a key component affecting the quality of air purification. As the purification time gradually increases, the filtration function of the filter in the existing purification equipment will gradually decline. If it is not replaced in time, it will not only affect the purification efficiency of the purification equipment, but may also affect the air quality in the environment due to the large amount of pollutants adhering to the filter, thus affecting the health of users. Summary of the Invention

[0004] Therefore, it is necessary to provide a purification device and a purification device control method that can improve purification efficiency in response to the above-mentioned technical problems.

[0005] In a first aspect, this application provides a purification device, the purification device comprising:

[0010] A controller is connected to the filter assembly, the drive mechanism, and the purification capacity detection assembly respectively. The controller is used to acquire purification capacity detection data of the filter in use of the purification equipment. When it is determined from the purification capacity detection data that the filter in use meets the filter replacement conditions, the controller controls the filter assembly of the purification equipment to rotate, and rotates other usable filters in the filter assembly to the air inlet.

[0011] In one embodiment, the controller controls the filter assembly of the purification device to rotate by a preset angle to obtain the purification capacity detection data of the candidate filter that is currently opposite the air inlet of the purification device; when it is determined from the purification capacity detection data of the candidate filter that the candidate filter does not meet the filter replacement conditions, the candidate filter is determined to be a usable filter.

[0012] In one embodiment, when the controller determines that the candidate filter meets the filter replacement condition based on the purification capacity detection data of the candidate filter, it returns to the step of controlling the filter assembly of the purification device to rotate by a preset angle and detecting the purification capacity detection data of the candidate filter currently opposite the air inlet of the purification device, until all filters in the purification device meet the filter replacement condition.

[0013] In one embodiment, the controller controls the filter assembly of the purification device to rotate sequentially by a preset angle, and detects the purification capacity data of the filter screen opposite the air inlet of the purification device after each rotation; when it is determined from the purification capacity detection data of each filter screen that there is a candidate filter screen that does not meet the filter screen replacement conditions, the candidate filter screen is determined as a usable filter screen; a target rotation angle is determined based on the position of the usable filter screen; the filter assembly is controlled to rotate based on the target rotation angle, so as to rotate the usable filter screen to the air inlet.

[0014] In one embodiment, when the controller determines, based on the purification capacity detection data of each filter, that there are multiple candidate filters that do not meet the filter replacement conditions, it determines the purification capacity value of each candidate filter based on the purification capacity detection data of each candidate filter; sorts the purification capacity values ​​of each candidate filter in descending order, and determines the candidate filter corresponding to the maximum purification capacity value as the usable filter; determines a target rotation angle based on the position of the usable filter; and controls the filter assembly to rotate based on the target rotation angle, rotating the usable filter to the air inlet.

[0015] In one embodiment, the purification device further includes an air outlet;

[0016] The purification capacity detection component includes:

[0017] An inlet dust detection component is installed at the air inlet to detect the ambient dust concentration at the air inlet.

[0018] An outlet dust detection component is installed at the air outlet to detect the concentration of purified dust at the air outlet.

[0019] The controller is connected to the inlet dust detection component and the outlet dust detection component respectively, and is used to determine the purification capacity value of the filter in use based on the concentration difference between the ambient dust concentration at the air inlet of the purification equipment and the purified dust concentration at the air outlet of the purification equipment; when the purification capacity value of the filter in use is less than or equal to a preset capacity threshold, it is determined that the filter in use meets the filter replacement conditions.

[0020] Secondly, this application also provides a method for controlling a purification device, the method comprising:

[0021] Obtain test data on the purification capacity of filters during the use of purification equipment;

[0022] When the filter in use is determined to meet the filter replacement conditions based on the purification capacity detection data, the filter assembly of the purification equipment is controlled to rotate, and other usable filters in the filter assembly are rotated to the air inlet; the filter assembly includes at least three filters.

[0023] In one embodiment, controlling the rotation of the filter assembly of the purification device to rotate other usable filters in the filter assembly toward the air inlet includes:

[0024] Control the filter component of the purification device to rotate by a preset angle, and obtain the purification capacity detection data of the candidate filter that is currently opposite to the air inlet of the purification device;

[0025] When the purification capacity test data of the candidate filter determines that the candidate filter does not meet the filter replacement conditions, the candidate filter is determined to be a usable filter.

[0026] In one embodiment, the method further includes:

[0027] When it is determined, based on the purification capacity detection data of the candidate filter, that the candidate filter meets the filter replacement condition, the process returns to the step of controlling the filter assembly of the purification equipment to rotate by a preset angle and detecting the purification capacity detection data of the candidate filter currently opposite the air inlet of the purification equipment, until all filters in the purification equipment meet the filter replacement condition.

[0028] In one embodiment, controlling the rotation of the filter assembly of the purification device to rotate other usable filters in the filter assembly toward the air inlet includes:

[0029] The filter components of the purification equipment are controlled to rotate sequentially by a preset angle, and the purification capacity data of the filter screen opposite the air inlet of the purification equipment is detected after each rotation.

[0030] When it is determined, based on the purification capacity test data of each filter, that there is a candidate filter that does not meet the filter replacement conditions, the candidate filter is determined as a usable filter.

[0031] The target rotation angle is determined based on the location of the available filter.

[0032] The filter assembly is rotated based on the target rotation angle, so that the usable filter is rotated to the air inlet.

[0033] In one embodiment, the method further includes:

[0034] When it is determined, based on the purification capacity test data of each filter, that there are multiple candidate filters that do not meet the filter replacement conditions, the purification capacity value of each filter is determined based on the purification capacity test data of each filter.

[0035] The purification capacity values ​​of each candidate filter are sorted in descending order, and the candidate filter with the highest purification capacity value is determined as the usable filter.

[0036] The target rotation angle is determined based on the location of the available filter.

[0037] The filter assembly is rotated based on the target rotation angle, so that the usable filter is rotated to the air inlet.

[0038] In one embodiment, the purification capacity detection data includes the ambient dust concentration at the air inlet of the purification equipment and the purified dust concentration at the air outlet of the purification equipment.

[0039] The step of determining whether the filter in use meets the filter replacement conditions based on the purification capacity detection data includes:

[0040] The purification capacity value of the filter in use is determined based on the concentration difference between the ambient dust concentration at the air inlet of the purification equipment and the purified dust concentration at the air outlet of the purification equipment.

[0041] When the purification capacity value of the filter in use is less than or equal to a preset capacity threshold, the filter in use is determined to meet the filter replacement conditions.

[0042] The aforementioned purification equipment and its control method include an air inlet, a filter assembly, a drive mechanism, a purification capacity detection component, and a controller. The controller acquires purification capacity detection data of the filter in use through the purification capacity detection component. This data reflects the purification capacity of the filter. When the data determines that the filter meets the replacement requirements, the controller controls the filter assembly to rotate via the drive mechanism. This rotates other usable filters (excluding the filter in use) to the air inlet of the purification equipment. Air purification is then performed using these replaced, usable filters. This avoids the problems of poor air quality and low purification efficiency caused by using filters with insufficient purification capacity, effectively improving the purification efficiency of the equipment.

[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] Air purification equipment draws in air from the environment and filters it through built-in filters, removing dust, odors, and pollutants to effectively improve air quality.

[0054] Traditional air purification equipment typically features a fixed filter at the air inlet, which adsorbs pollutants to achieve air purification. Therefore, the equipment is limited by the filter's lifespan and requires regular filter replacement to maintain effectiveness. Filter lifespan is often related to the operating environment and duration of use. If filters in traditional air purification equipment are not replaced in a timely manner, not only will they fail to purify the air effectively, but filter clogging can also increase the overall air resistance of the equipment, increasing power consumption and severely impacting purification efficiency.

[0055] Based on this, such as Figure 1 As shown, in this embodiment, a purification device 100 is provided, including:

[0056] The air inlet 101, filter assembly 102, drive mechanism 103, purification capacity detection assembly 104, and controller 105 connected to filter assembly 102, drive mechanism 103, and purification capacity detection assembly 104 respectively.

[0057] The air inlet 101 can be considered as the entrance connecting the external environment and the interior of the purification device 100. Air to be purified enters the purification device 100 through the air inlet 101 and comes into contact with the filter screen 1021 in the filter assembly 102 of the purification device 100 for filtration, thereby obtaining clean air. Understandably, the specific location of the air inlet 101 on the purification device 100 can be determined according to actual conditions, such as being located at the bottom or side of the purification device 100.

[0058] The filter assembly 102 includes at least three filters. Each filter is a purification medium carrier used to filter and purify air. When air comes into contact with the filters, pollutants in the air are adsorbed and removed by the purification medium on the filters, resulting in clean air being released into the environment. Understandably, the type and number of filters in the filter assembly 102 can be determined based on the actual conditions of the purification equipment 100.

[0059] It should be noted that the filter assembly 102 contains at least three filters, including one in-use filter 1021 and other usable filters 1022. The in-use filter 1021 is located opposite the air inlet 101. When the purification device 100 is running, the air to be purified enters the purification device 100 through the air inlet 101 and directly contacts the in-use filter 1021 for filtration, resulting in filtered clean air. The other usable filters 1022 will not come into contact with the air to be purified; they are only provided as backup filters in the purification device 100.

[0060] The drive mechanism 103 is a mechanism for providing power to rotate the filter assembly 102. The drive mechanism 103 is connected to both the filter assembly 102 and the controller 105, and is controlled by the controller 105 to drive the filter assembly 102 to rotate, that is, to drive the multiple filter screens 1021 in the filter assembly 102 to rotate relative to the housing of the purification device 100. It is understood that the drive mechanism 103 can be any type of drive device, as long as it can drive the filter assembly 102 to rotate.

[0061] In one embodiment, the drive mechanism 103 includes a stepper motor, a turntable, and a tray. The turntable and the tray are connected by a snap-fit, and a spring is provided at the bottom of the tray to lift the tray. The stepper motor is connected to the turntable by gears. When the drive mechanism is working, the stepper motor drives the gears at the bottom of the turntable to rotate the turntable. The tray fixes the filter assembly to the base and rotates with the turntable.

[0062] The purification capacity detection component 104 is a detection component used to detect the purification capacity of the filter screen in the filter assembly 102. The purification capacity detection component 104 is connected to the controller 105, and can detect the purification capacity of the filter screen in the filter assembly 102 that needs to be tested, and send the obtained purification capacity detection data to the controller 105. It is understood that the purification capacity detection component 104 can be any detection component capable of detecting the purification capacity of the filter screen. The specific component type and setting location of the purification capacity detection component 104 can be determined according to the actual situation. For example, the purification capacity detection component 104 can be an airflow detection component, set in the air outlet channel of the purification device 100 (not shown in the figure), to detect the airflow of the purification device 100 and obtain purification capacity detection data. The purification capacity detection component 104 can also be a volume detection component, set on the fan of the purification device 100 (not shown in the figure), to detect the operating volume of the purification device 100 and obtain purification capacity detection data.

[0063] The controller 105 is used to acquire the purification capacity detection data of the filter 1021 in use in the purification equipment 100. When it is determined from the purification capacity detection data that the filter 1021 in use meets the filter replacement conditions, the controller controls the filter assembly 102 of the purification equipment 100 to rotate, and rotates other usable filters 1022 in the filter assembly 102 to the air inlet 101.

[0064] The controller 105 is a control device that can receive purification capacity detection data, make logical judgments based on the purification capacity detection data, generate instructions, and send them. After being connected to the purification capacity detection component 104 and the drive mechanism 103 respectively, the controller 105 can obtain the purification capacity detection data of the filter 1021 in use in the purification equipment 100 through the purification capacity detection component 104. When it is determined from the purification capacity detection data that the filter 1021 in use needs to be replaced, the controller can control the drive mechanism 103 connected to it to drive the filter component 102 to rotate, so that other filters 1022 in the filter component 102 can replace the original filter 1021 in use.

[0065] Filter replacement conditions are preset criteria used to determine whether a filter needs to be replaced. These conditions are generated based on the filter's purification capacity. When the filter meets the replacement conditions, it means that its purification capacity is no longer sufficient for the user's needs and it must be replaced.

[0066] Specifically, the purification capacity detection component 104 detects the purification capacity of the filter 1021 in use in the purification equipment 100, obtains the purification capacity detection data of the filter 1021 in use, and sends it to the controller 105. The controller 105 receives the purification capacity detection data that reflects the purification capacity of the filter 1021, and determines whether the filter 1021 in use meets the filter replacement conditions based on the purification capacity detection data. When it is determined that the filter 1021 in use meets the filter replacement conditions, the controller 105 generates a rotation command and sends the rotation command to the drive mechanism 103. In response to the rotation command, the drive mechanism 103 drives the filter assembly 102 to rotate, rotating other usable filters 1022 in the filter assembly 102 to the air inlet 101, replacing the original filter 1021 in use. The purification equipment 100 will then operate an air cleaning mode based on the usable filters 1022.

[0067] The aforementioned purification equipment includes an air inlet, a filter assembly, a drive mechanism, a purification capacity detection component, and a controller. The controller acquires purification capacity detection data of the filter in use through the purification capacity detection component. This data reflects the purification capacity of the filter. When the data determines that the filter in use meets the replacement requirements, the controller controls the filter assembly to rotate via the drive mechanism. This rotates other usable filters (excluding the one in use) to the air inlet of the purification equipment. Air purification is then performed using these replaced, usable filters. This avoids the problems of poor air quality and low purification efficiency caused by using filters with insufficient purification capacity, effectively improving the purification efficiency of the equipment.

[0068] Since the filtration assembly of a purification device contains at least three filters, determining which usable filter can be replaced when the filter in use meets the replacement requirements is a crucial step in improving the purification efficiency of the device. The following examples illustrate methods for determining usable filters.

[0069] In one embodiment, the controller controls the filter assembly of the purification equipment to rotate by a preset angle and detects the purification capacity detection data of the candidate filter that is currently opposite the air inlet of the purification equipment; when it is determined from the purification capacity detection data of the candidate filter that the candidate filter does not meet the filter replacement conditions, the candidate filter is determined to be a usable filter.

[0070] The preset angle is the angle the filter assembly needs to rotate to face the air inlet when the filter adjacent to the one currently facing the air inlet is rotated. The specific value of the preset angle is determined based on the number of filters in the filter assembly and the actual design. For example, if the filter assembly includes 4 filters and the rotation range of the 4 filters is 360°, the preset angle can be considered to be 90°. If the filter assembly includes 3 filters and the rotation range of the 3 filters is 180°, the preset angle can be considered to be 60°.

[0071] Specifically, when the controller determines that the filter in use in the purification equipment does not meet the filter replacement conditions, it generates a rotation command based on a preset angle and sends the rotation command to the drive mechanism in the purification equipment. In response to the rotation command, the drive mechanism drives the filter component in the purification equipment to rotate by a preset angle, rotating the filter adjacent to the filter in use to the air inlet. The filter at the air inlet at this time is the filter to be selected.

[0072] The controller generates a filter detection command and sends it to the purification capacity detection component. Responding to the command, the component performs purification capacity detection on the candidate filter, obtaining its data and sending it to the controller. The controller receives this data and determines whether the filter meets the replacement requirements. If the filter does not meet the replacement requirements, it means the filter rotated to the air inlet has sufficient purification capacity to meet the user's needs. The controller then designates the filter as usable and operates the air purification equipment in air purification mode based on this usable filter, providing the user with clean air that meets their requirements.

[0073] In this embodiment, when it is determined that the filter in use needs to be replaced, the filter assembly can be rotated at a preset angle to identify a candidate filter with higher purification capacity as the usable filter, and the filter in use can be replaced. Subsequently, the purification equipment can purify the air based on the usable filter with higher purification capacity, which effectively improves the purification efficiency of the purification equipment.

[0074] Furthermore, other filters in the filtration assembly may have lower purification capabilities due to environmental factors or human intervention. Therefore, in some embodiments, when the controller determines that a candidate filter meets the filter replacement conditions based on its purification capability detection data, it returns to the step of controlling the filtration assembly of the purification equipment to rotate by a preset angle and detecting the purification capability detection data of the candidate filter currently opposite the air inlet of the purification equipment, until all filters in the purification equipment meet the filter replacement conditions.

[0075] Specifically, if the controller determines, based on the filter capacity detection data, that a candidate filter also meets the filter replacement conditions, it indicates that the filter's purification capacity still cannot meet the user's needs. The controller will continue to generate a rotation command based on a preset angle and send it to the drive mechanism in the purification equipment. Responding to the rotation command, the drive mechanism rotates the filter components in the purification equipment by a preset angle, rotating the filter adjacent to the current candidate filter to the air inlet. The filter at the air inlet is then replaced as the candidate filter, and the purification capacity detection component checks the purification capacity of the replaced filter, and so on. If, during the above rotation detection process, it is determined that a candidate filter does not meet the filter replacement conditions, this filter is identified as usable, and the purification equipment performs air purification operations based on the usable filter. If, during the above rotation detection process, it is determined that all filters in the purification equipment meet the filter replacement conditions, it indicates that there are no filters in the purification equipment that meet the user's needs, and the controller stops the rotation detection.

[0076] In some embodiments, if it is determined that all filters in the purification equipment meet the filter replacement conditions, the controller will generate a filter replacement prompt after stopping the rotation detection and push the filter replacement prompt to the user to prompt the user to replace the filter.

[0077] In the above embodiments, when it is determined that the purification capacity of the candidate filter also does not meet the user's needs, the controller will continue to control the rotation of the filter assembly to search for a usable component with purification capacity that meets the user's needs from among the various filters in the filter assembly, thereby improving the purification efficiency of the purification equipment. When there are no filters in the purification equipment that meet the user's needs, the controller controls the filter assembly to stop rotating, avoiding adding unnecessary detection processes and increasing the computational simplicity of the purification equipment control process.

[0078] In addition to the aforementioned method of determining usable filters while rotating, in other embodiments, the controller controls the filter components of the purification equipment to rotate sequentially by a preset angle, and detects the purification capacity data of the filter opposite the air inlet of the purification equipment after each rotation; when it is determined from the purification capacity detection data of each filter that there is a candidate filter that does not meet the filter replacement conditions, the candidate filter is determined as a usable filter; the target rotation angle is determined based on the position of the usable filter; and the filter components are controlled to rotate based on the target rotation angle, rotating the usable filter to the air inlet.

[0079] The target rotation angle is the angle required to rotate the usable filter to the air inlet. Understandably, the target rotation angle is related to the position of the usable filter and the preset rotation angle of the filter assembly. For example, the filter assembly includes four filters: filter 1, filter 2, filter 3, and filter 4, and the rotation range of the filter assembly is 360°. If the controller controls the filter assembly to rotate sequentially, and filter 4 is currently rotating to the air inlet, and the controller determines that filter 2 is the usable filter, then the target rotation angle is 180°. If the controller determines that filter 3 is the usable filter, then the target rotation angle is 90°; and if the controller determines that filter 4 is the usable filter, then the target rotation angle is 0°.

[0080] Specifically, when the controller determines that the filters in the purification equipment meet the filter replacement requirements, it sequentially generates rotation commands based on preset angles and sends these commands to the drive mechanism within the purification equipment. Responding to the rotation commands, the drive mechanism drives the filter components within the purification equipment to rotate sequentially by preset angles, rotating each filter in the filter components to the air inlet in turn. During this sequential rotation, after each rotation, the controller generates a filter detection command and sends it to the purification capacity detection component. Responding to the filter detection command, the purification capacity detection component sequentially detects the purification capacity of the filters rotated to the air inlet, obtaining purification capacity detection data for each filter.

[0081] The controller acquires purification capacity detection data for each filter and determines the filter replacement conditions based on this data. Filters that do not meet the replacement conditions are identified as candidate filters. When only one candidate filter that does not meet the replacement conditions is identified, the controller designates this single candidate filter as usable and determines its location. Based on the location of the usable filter, a target rotation angle is determined, and a rotation command is generated and sent to the drive mechanism. The drive mechanism responds to the rotation command, driving the filter assembly to rotate by the target angle, moving the usable filter to the air inlet. Subsequent control of the purification equipment operates in air purification mode based on the usable filter, filtering the air to be purified and providing users with clean air that meets their needs, effectively improving the purification efficiency of the equipment.

[0082] Furthermore, in some embodiments, when the controller determines, based on the purification capacity detection data of each filter, that there are multiple candidate filters that do not meet the filter replacement conditions, it determines the purification capacity value of each candidate filter based on the purification capacity detection data of each candidate filter; sorts the purification capacity values ​​of each candidate filter in descending order, and determines the candidate filter corresponding to the maximum purification capacity value as the usable filter; determines the target rotation angle based on the position of the usable filter; and controls the filter assembly to rotate based on the target rotation angle, rotating the usable filter to the air inlet.

[0083] Specifically, when the controller determines that there are multiple candidate filters in the purification equipment that do not meet the filter replacement conditions, it determines the purification capacity value of each candidate filter based on the purification detection data of each candidate filter. The obtained purification capacity values ​​are then sorted in descending order, and the candidate filter corresponding to the highest purification capacity value is identified as the usable filter, and its location is determined. Based on the location of the usable filter, a target rotation angle is determined, and a rotation command is generated and sent to the drive mechanism. Responding to the rotation command, the drive mechanism drives the filter assembly to rotate by the target rotation angle, rotating the usable filter to the air inlet. Subsequently, the purification equipment operates in an air purification mode based on the usable filter, filtering the air to be purified through the usable filter to provide users with clean air that meets their needs.

[0084] In this embodiment, when there are multiple candidate filters in the purification equipment that meet the user's needs, the controller can select the candidate filter with the highest purification capacity as the usable filter based on the purification capacity value of each candidate filter, which effectively improves the purification capacity and purification efficiency of the purification equipment.

[0085] Whether a filter meets the replacement criteria is a key factor in determining whether it needs replacement and which filters are usable. This requirement is based on the filter's purification capacity testing data. Therefore, accurately determining whether a filter meets the replacement criteria based on this data is a crucial step affecting the effectiveness of filter replacement in air purification equipment.

[0086] In order to make an accurate judgment, in one embodiment, such as Figure 2 As shown, a purification device 200 is provided, wherein the purification device 200 includes an air inlet 201, a filter assembly 202, a drive mechanism 203, a purification capacity detection assembly 204, and a controller 205 connected to the filter assembly 202, the drive mechanism 203, and the purification capacity detection assembly 204 respectively, and also includes an air outlet 206.

[0087] The filter assembly 202 includes a filter 2021 in use and other spare filters 2022.

[0088] Purification capacity detection component 204 includes:

[0089] An inlet dust detection component 2041 is provided at the air inlet 201 to detect the ambient dust concentration at the air inlet 201.

[0090] The outlet dust detection component 2042, wherein the inlet dust detection component 2042 is installed at the air outlet 206 and is used to detect the concentration of purified dust at the air outlet 206.

[0091] Both the inlet dust detection component 2041 and the outlet dust detection component 2042 are dust sensors capable of detecting the degree of dust pollution in the air and obtaining the dust concentration. Examples include laser dust sensors and electrostatic dust sensors.

[0092] The inlet dust detection component 2041 is located at the air inlet 201, therefore it detects the dust concentration in the unpurified air, i.e., the ambient dust concentration. The outlet dust detection component 2042 is located at the air outlet 206, therefore it detects the dust concentration in the purified air, i.e., the purified dust concentration.

[0093] The controller 205 is connected to the inlet dust detection component 2041 and the outlet dust concentration detection component 2042 respectively. It is used to determine the purification capacity value of the filter 2021 in use based on the concentration difference between the ambient dust concentration at the air inlet 201 of the purification equipment 200 and the purified dust concentration at the air outlet 206 of the purification equipment 200. When the purification capacity value of the filter 2021 in use is less than or equal to the preset capacity threshold, it is determined that the filter 2021 in use meets the filter replacement conditions.

[0094] The preset capacity threshold is a parameter used to determine whether the filter needs to be replaced. When the filter's purification capacity value is greater than the preset capacity threshold, it can be considered that the filter's purification capacity value meets the user's needs and does not need to be replaced. When the filter's purification capacity value is less than or equal to the preset capacity threshold, it means that the filter's purification capacity value no longer meets the user's needs and needs to be replaced.

[0095] Understandably, preset capacity thresholds can be determined by designers based on the actual purification capacity required when the filter needs replacement during actual use of the air purifier. For example, if the air purifier is installed in a home environment, the higher the purification capacity of the filter to meet user needs, the higher the preset capacity threshold will be, resulting in cleaner purified air. If the air purifier is installed in an environment with high dust concentration, the lower the purification capacity of the filter to meet user needs, and the lower the preset capacity threshold will be, avoiding frequent filter replacements and reducing user costs.

[0096] Specifically, the inlet dust detection component 2041 detects the air at the air inlet 201 to obtain the ambient dust concentration and sends it to the controller 205. The outlet dust concentration detection component 2042 detects the air at the air outlet 206 to obtain the purified dust concentration and sends it to the controller 205. The controller 205 calculates the concentration difference between the received ambient and purified dust concentrations; this concentration difference represents the dust concentration that the filter can filter. The controller 205 determines this concentration difference as the purification capacity value of the filter 2021 in use and compares it with a preset capacity threshold. If the purification capacity value of the filter 2021 in use is less than or equal to the preset capacity threshold, it indicates that the purification capacity value of the filter 2021 in use no longer meets the user's needs and needs to be replaced. The controller 205 determines that the filter 2021 in use meets the filter replacement conditions.

[0097] In this embodiment, by setting dust detection components at the air inlet and air outlet of the purification equipment, the dust concentration in the air at the air inlet and air outlet is detected respectively. The purification capacity value of the filter in use can be accurately determined based on the concentration difference of the detected data. Subsequently, based on the purification capacity value of the filter and the pre-capacity threshold, it can be quickly and accurately determined whether the filter in use meets the filter replacement conditions, which effectively improves the accuracy of the judgment on whether the filter meets the filter replacement conditions, thereby improving the purification efficiency of the purification equipment.

[0098] Furthermore, in some embodiments, the above-described determination method can be used to determine whether the filter replacement conditions are met during the filter determination process.

[0099] Specifically, when each filter rotates to the air inlet, the inlet dust detection component will detect the ambient dust concentration at the air inlet, and the outlet dust concentration detection component will detect the purified dust concentration at the air outlet. The concentration difference between the filters currently rotating to the air inlet is obtained, which is the purification capacity value of the filters currently rotating to the air inlet. The purification capacity value of the filters is compared with a preset capacity threshold. If the purification capacity value of the filters is less than or equal to the preset capacity threshold, it is determined that the filters currently rotating to the air inlet meet the filter replacement conditions.

[0100] In some embodiments, such as Figure 3 As shown, an air purifier 300 is provided, comprising:

[0101] The system includes an air inlet 301, an air outlet 302, a filter assembly 303, a drive mechanism 304, an inlet dust sensor 305, an outlet dust sensor 306, and a controller 307 that is connected to the filter assembly 303, the drive mechanism 304, the inlet dust sensor 305, and the outlet dust sensor 306, respectively.

[0102] The filter assembly 303 includes four filters: a first filter 3031, a second filter 3032, a third filter 3033, and a fourth filter 3034. The four filters form a cylindrical structure, and the filter assembly 303 can rotate 360°. The top of the cylinder is connected to the air outlet 302, and the air inlet 301 is located on the opposite side of the cylinder.

[0103] The drive mechanism 304 is connected to the filter assembly 303 and the controller 307 respectively, and is controlled by the controller 307 to drive the filter assembly 303 to rotate.

[0104] An inlet dust sensor 305 is installed at the air inlet 301 to detect the ambient dust concentration at the air inlet 301.

[0105] The outlet dust sensor 306 is installed at the air outlet 302 to detect the concentration of purified dust at the air outlet 302.

[0106] Taking the first filter 3031 as an example, the air purifier 300 operates in air purification mode based on the first filter 3031. The inlet dust sensor 305 detects the ambient dust concentration at the air inlet 301 and sends it to the controller 307. The outlet dust sensor 306 detects the purified dust concentration at the air outlet 302 and sends it to the controller 307. The controller determines the purification capacity value of the first filter 3031 based on the concentration difference between the ambient dust concentration and the purified dust concentration.

[0107] The purification capacity value of the first filter 3031 is compared with a preset capacity threshold. If the purification capacity value Z of the first filter 3031 is less than or equal to the preset capacity threshold 40, then the first filter 3031 meets the filter replacement condition. The controller 307 generates rotation commands sequentially based on a 90° rotation angle and sends the rotation commands to the drive mechanism 304. In response to the rotation commands, the drive mechanism 304 drives the filter assembly 303 to rotate 90° sequentially, rotating the second filter 3032, the third filter 3033, and the fourth filter 3034 in the filter assembly 303 to the air inlet in sequence. During the sequential rotation, after each rotation, the controller 307 generates a filter detection command and sends the filter detection command to the inlet dust sensor 305 and the outlet dust sensor 306. In response to the filter detection command, the inlet dust sensor 305 and the outlet dust sensor 306 sequentially detect the dust concentration of the air at the air inlet 301 and the air outlet 302 when the second filter 3032, the third filter 3033 and the fourth filter 3034 rotate to the air inlet 301, obtain the ambient dust concentration and the purified dust concentration and send them to the controller 307.

[0108] The controller 307 calculates the purification capacity values ​​Z1, Z2, Z3, and Z4 for each filter based on the ambient dust concentration and the purification dust concentration corresponding to each filter. It then compares these purification capacity values ​​with a preset threshold 40. If only one purification capacity value is greater than the preset threshold (e.g., Z3 > 40), the filter corresponding to that value (the third filter 3033) is determined to be usable. If multiple purification capacity values ​​are greater than the preset threshold (e.g., Z2 and Z3, or Z2 and Z4, or Z3, Z4, or Z2, Z3, Z4 > 40), the purification capacity values ​​greater than the preset threshold are sorted in descending order, and the filter with the highest purification capacity value is determined to be usable. For example, if Z3 > Z4 > Z2, then the third filter 3033 corresponding to Z3 is determined to be usable.

[0109] The controller 307 determines the target rotation angle based on the position of the usable filter and generates a rotation command based on the target rotation angle, which is then sent to the drive mechanism 304. In response to the rotation command, the drive mechanism 304 drives the filter assembly 303 to rotate by the target rotation angle, rotating the usable filter to the air inlet 301.

[0110] The air purifier in the above embodiment can achieve 360° rotation of the filter component through the drive structure. At the same time, a dust sensor is set to detect the dust concentration in the air. Based on the detected data, the filter is intelligently rotated to adjust to the optimal position, which can improve the purification efficiency of the air purifier.

[0111] Based on the same inventive concept, this application also provides a purification equipment control method applied to the above-mentioned purification equipment.

[0112] In some embodiments, such as Figure 4 As shown, a method for controlling a purification device is provided. Taking the application of this method to a controller of a purification device as an example, the method includes the following steps:

[0113] S402, Obtain the purification capacity test data of the filter screen during the use of the purification equipment.

[0114] S404, when the filter in use is determined to meet the filter replacement conditions based on the purification capacity test data, the filter assembly of the purification equipment is controlled to rotate, and other usable filters in the filter assembly are rotated to the air inlet; the filter assembly includes at least three filters.

[0115] Specifically, the controller receives purification capacity detection data from the purification capacity detection component, which reflects the filter's purification capacity. Based on this data, it determines whether the filter in use meets the replacement requirements. When the replacement requirement is met, the controller generates a rotation command and sends it to the drive mechanism. Responding to the rotation command, the drive mechanism rotates the filter assembly, moving other usable filters to the air inlet to replace the currently used filter. The purification equipment then operates in air cleaning mode based on the available filters.

[0116] The above-mentioned purification equipment control method involves the controller acquiring purification capacity detection data of the filter in use through a purification capacity detection component. This data reflects the purification capacity of the filter. When the data determines that the filter in use meets the replacement requirements, the controller can control the filter assembly to rotate via a drive mechanism. This rotates the other usable filters (excluding the filter in use) to the air inlet of the purification equipment. Air purification is then performed using the replaced usable filters. This method avoids the problems of poor air quality and low purification efficiency caused by using filters with insufficient purification capacity, effectively improving the purification efficiency of the purification equipment.

[0117] In one embodiment, controlling the rotation of the filter assembly of the purification device to rotate other usable filters in the filter assembly toward the air inlet includes:

[0118] The system controls the filter components of the purification equipment to rotate at a preset angle, acquiring the purification capacity detection data of the candidate filter currently opposite the air inlet of the purification equipment. If the candidate filter does not meet the filter replacement conditions based on the purification capacity detection data, the candidate filter is determined to be a usable filter.

[0119] Specifically, when the controller determines that the filter in use in the purification equipment does not meet the filter replacement conditions, it generates a rotation command based on a preset angle and sends the rotation command to the drive mechanism in the purification equipment. In response to the rotation command, the drive mechanism drives the filter component in the purification equipment to rotate by a preset angle, rotating the filter adjacent to the filter in use to the air inlet. The filter at the air inlet at this time is the filter to be selected.

[0120] The controller then generates a filter detection command and sends it to the purification capacity detection component. Responding to the command, the component performs a purification capacity test on the candidate filter, obtaining its data and sending it to the controller. The controller receives this data and determines whether the filter meets the replacement requirements. If the filter does not meet the replacement requirements, it means the filter rotated to the air inlet has sufficient purification capacity to meet the user's needs. The controller then designates the filter as usable and operates the air purification system in air purification mode based on this usable filter. This allows the system to filter the air, providing clean air that meets the user's requirements and effectively improving the purification efficiency of the system.

[0121] In one embodiment, the purification equipment control method further includes:

[0122] When the purification capacity test data of the candidate filter determines that the candidate filter meets the filter replacement conditions, the process returns to the step of controlling the filter component of the purification equipment to rotate by a preset angle and detecting the purification capacity test data of the candidate filter currently opposite the air inlet of the purification equipment, until all filters in the purification equipment meet the filter replacement conditions.

[0123] Specifically, if the controller determines, based on the filter capacity detection data, that a candidate filter also meets the filter replacement conditions, it indicates that the filter's purification capacity still cannot meet the user's needs. The controller will continue to generate a rotation command based on a preset angle and send it to the drive mechanism in the purification equipment. Responding to the rotation command, the drive mechanism rotates the filter components in the purification equipment by a preset angle, rotating the filter adjacent to the current candidate filter to the air inlet. The filter at the air inlet is then replaced as the candidate filter, and the purification capacity detection component checks the purification capacity of the replaced filter, and so on. If, during the above rotation detection process, it is determined that a candidate filter does not meet the filter replacement conditions, this filter is identified as usable, and the purification equipment performs air purification operations based on the usable filter. If, during the above rotation detection process, it is determined that all filters in the purification equipment meet the filter replacement conditions, it indicates that there are no filters in the purification equipment that meet the user's needs, and the controller stops the rotation detection.

[0124] In this embodiment, when it is determined that the purification capacity of the candidate filter also does not meet the user's needs, the controller will continue to control the rotation of the filter assembly to search for a usable component with purification capacity that meets the user's needs from among the various filters in the filter assembly, thereby improving the purification efficiency of the purification equipment. When there are no filters in the purification equipment that meet the user's needs, the controller controls the filter assembly to stop rotating, avoiding adding unnecessary detection processes and increasing the computational simplicity of the purification equipment control process.

[0125] In one embodiment, such as Figure 5 As shown, the filter assembly of the purification equipment is rotated, turning other usable filters in the filter assembly toward the air inlet.

[0126] S502 controls the filter components of the purification equipment to rotate sequentially by a preset angle, and detects the purification capacity data of the filter screen opposite the air inlet of the purification equipment after each rotation.

[0127] S504: When it is determined, based on the purification capacity test data of each filter, that there is a candidate filter that does not meet the filter replacement conditions, the candidate filter is determined as a usable filter.

[0128] S506 determines the target rotation angle based on the location of the available filter.

[0129] S508 controls the rotation of the filter assembly based on the target rotation angle, rotating the usable filter towards the air inlet.

[0130] Specifically, when the controller determines that the filters in the purification equipment meet the filter replacement requirements, it sequentially generates rotation commands based on preset angles and sends these commands to the drive mechanism within the purification equipment. Responding to the rotation commands, the drive mechanism drives the filter components within the purification equipment to rotate sequentially by preset angles, rotating each filter in the filter components to the air inlet in turn. During this sequential rotation, after each rotation, the controller generates a filter detection command and sends it to the purification capacity detection component. Responding to the filter detection command, the purification capacity detection component sequentially detects the purification capacity of the filters rotated to the air inlet, obtaining purification capacity detection data for each filter.

[0131] The controller acquires purification capacity detection data for each filter and determines the filter replacement conditions based on this data. Filters that do not meet the replacement conditions are identified as candidate filters. When only one candidate filter that does not meet the replacement conditions is identified, the controller designates this single candidate filter as usable and determines its location. Based on the location of the usable filter, a target rotation angle is determined, and a rotation command is generated and sent to the drive mechanism. The drive mechanism responds to the rotation command, driving the filter assembly to rotate by the target angle, moving the usable filter to the air inlet. Subsequent control of the purification equipment operates in air purification mode based on the usable filter, filtering the air to be purified and providing users with clean air that meets their needs, effectively improving the purification efficiency of the equipment.

[0132] In some embodiments, such as Figure 6 As shown, the purification equipment control method also includes the following steps:

[0133] S602, when it is determined from the purification capacity test data of each filter that there are multiple candidate filters that do not meet the filter replacement conditions, the purification capacity value of each filter is determined from the purification capacity test data of each filter.

[0134] S604, sort the purification capacity values ​​of each candidate filter in descending order, and determine the candidate filter with the highest purification capacity value as the usable filter.

[0135] S606 determines the target rotation angle based on the location of the available filter.

[0136] S608 controls the rotation of the filter assembly based on the target rotation angle, rotating the usable filter towards the air inlet.

[0137] Specifically, when the controller determines that there are multiple candidate filters in the purification equipment that do not meet the filter replacement conditions, it determines the purification capacity value of each candidate filter based on the purification detection data of each candidate filter. The obtained purification capacity values ​​are then sorted in descending order, and the candidate filter corresponding to the highest purification capacity value is identified as the usable filter, and its location is determined. Based on the location of the usable filter, a target rotation angle is determined, and a rotation command is generated and sent to the drive mechanism. Responding to the rotation command, the drive mechanism drives the filter assembly to rotate by the target rotation angle, rotating the usable filter to the air inlet. Subsequently, the purification equipment operates in an air purification mode based on the usable filter, filtering the air to be purified through the usable filter to provide users with clean air that meets their needs.

[0138] In this embodiment, when there are multiple candidate filters in the purification equipment that meet the user's needs, the controller can select the candidate filter with the highest purification capacity as the usable filter based on the purification capacity value of each candidate filter, which effectively improves the purification capacity and purification efficiency of the purification equipment.

[0139] In one embodiment, the purification capacity test data includes the ambient dust concentration at the air inlet of the purification equipment and the purified dust concentration at the air outlet of the purification equipment. Determining whether the filter in use meets the filter replacement conditions based on the purification capacity test data includes:

[0140] The purification capacity of the filter in use is determined based on the difference between the ambient dust concentration at the air inlet and the purified dust concentration at the air outlet. If the purification capacity of the filter in use is less than or equal to a preset capacity threshold, the filter is deemed ready for replacement.

[0141] Specifically, the controller acquires the ambient dust concentration obtained by detecting the air at the air inlet of the purification equipment, and the purified dust concentration obtained by detecting the air at the air outlet of the purification equipment. Based on the ambient dust concentration and the purified dust concentration, the controller calculates the concentration difference between the two concentrations; this concentration difference represents the dust concentration that the filter can filter. This concentration difference is determined as the purification capacity value of the filter in use, and it is compared with a preset capacity threshold. When the purification capacity value of the filter in use is less than or equal to the preset capacity threshold, it indicates that the purification capacity value of the filter in use no longer meets the user's needs and needs to be replaced. The controller determines that the filter in use meets the filter replacement conditions.

[0142] In this embodiment, by setting dust detection components at the air inlet and air outlet of the purification equipment, the dust concentration in the air at the air inlet and air outlet is detected respectively. The purification capacity value of the filter in use can be accurately determined based on the concentration difference of the detected data. Subsequently, based on the purification capacity value of the filter and the pre-capacity threshold, it can be quickly and accurately determined whether the filter in use meets the filter replacement conditions, which effectively improves the accuracy of the judgment on whether the filter meets the filter replacement conditions, thereby improving the purification efficiency of the purification equipment.

[0143] In one embodiment, before determining whether the filter in use meets the filter replacement conditions, the controller first compares the obtained ambient dust concentration with a preset dust concentration threshold. If the ambient dust concentration is less than the preset dust concentration threshold, it indicates that the ambient air quality is good at this time, and the controller can control the purification equipment to continue to purify the air based on the filter in use.

[0144] For example, when the preset dust concentration threshold is 35ug / m³ 3If the detected environmental dust concentration value X ≤ 35 ug / m³ 3 In this case, it can be assumed that there is no need to rotate the filter assembly, adjust the filter position, or replace the filter. When X > 35 ug / m 3 If the air quality is generally poor, it is necessary to test the purification capacity of the filter in use to determine whether it needs to be replaced.

[0145] In one embodiment, such as Figure 7 As shown, a method for controlling a purification device is provided, which is applied to... Figure 3 We will take air purifiers as an example to illustrate this.

[0146] First, the controller acquires the ambient dust concentration X1 obtained by detecting the dust concentration of the air at the air inlet, and the purified dust concentration Y1 obtained by detecting the air at the air outlet. It then calculates the concentration difference X1-Y1 between the ambient dust concentration and the purified dust concentration, and determines this concentration difference as the purification capacity value Z1 of the first filter.

[0147] The purification capacity value Z1 of the first filter is compared with a preset capacity threshold of 40. When Z1 > 40, the filter in use is determined to meet the filter replacement condition. The controller generates rotation commands sequentially based on 90°, controlling the filter assembly to rotate, and rotating each filter on the filter assembly to the air inlet in turn. After each filter is rotated to the air inlet, the ambient dust concentration and the purified dust concentration are detected. The concentration difference between the ambient dust concentration and the purified dust concentration corresponding to each filter is calculated, and thus the purification capacity values ​​Z2, Z3, and Z4 of each filter except the first filter are obtained.

[0148] The purification capacity values ​​Z2, Z3, and Z4 of each filter are compared with a preset capacity threshold of 40. If only one purification capacity value is greater than the preset threshold (i.e., Z2 / Z3 / Z4 > 40), the filter corresponding to that value is determined to be usable. If multiple purification capacity values ​​are greater than the preset threshold (i.e., Z2 and Z3, Z2 and Z4, Z3 and Z4, or Z2, Z3, and Z4 > 40), the purification capacity values ​​greater than the preset threshold are sorted in descending order, and the filter with the highest purification capacity value is determined to be usable. If Z1 / Z2 / Z3 ≤ 40, a filter replacement reminder is generated and pushed to the user.

[0149] The controller determines the target rotation angle based on the position of the usable filter, generates a rotation command based on the target rotation angle, and controls the filter assembly to rotate according to the rotation command, so that the usable filter is rotated to the air inlet.

[0150] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0151] Based on the same inventive concept, this application also provides a purification equipment control device for implementing the purification equipment control method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more purification equipment control device embodiments provided below can be found in the limitations of the purification equipment control method described above, and will not be repeated here.

[0152] In one embodiment, such as Figure 8 As shown, a purification equipment control device 800 is provided, including: a data acquisition module 801 and a control module 802, wherein:

[0153] The data acquisition module 801 is used to acquire the purification capacity test data of the filter screen during the use of the purification equipment.

[0154] The control module 802 is used to control the rotation of the filter assembly of the purification equipment when it is determined from the purification capacity detection data that the filter in use meets the filter replacement conditions, so as to rotate other usable filters in the filter assembly to the air inlet; the filter assembly includes at least three filters.

[0155] The aforementioned purification equipment control device uses a controller to acquire purification capacity detection data of the filter in use through a purification capacity detection component. This data reflects the purification capacity of the filter. When the data determines that the filter in use meets the replacement requirements, the controller can control the filter assembly to rotate via a drive mechanism. This rotates the other usable filters (excluding the filter in use) to the air inlet of the purification equipment. Air purification is then performed using the replaced usable filters, avoiding the problems of poor air quality and low purification efficiency caused by using filters with insufficient purification capacity. This effectively improves the purification efficiency of the purification equipment.

[0157] In one embodiment, the control module is further configured to: when it is determined from the purification capacity detection data of the candidate filter that the candidate filter meets the filter replacement conditions, return to the step of controlling the filter assembly of the purification equipment to rotate by a preset angle and detecting the purification capacity detection data of the candidate filter currently opposite the air inlet of the purification equipment, until all filters in the purification equipment meet the filter replacement conditions.

[0158] In one embodiment, the control module is further configured to: when it is determined from the purification capacity detection data of the candidate filter that the candidate filter meets the filter replacement conditions, return to the step of controlling the filter assembly of the purification equipment to rotate by a preset angle and detecting the purification capacity detection data of the candidate filter currently opposite the air inlet of the purification equipment, until all filters in the purification equipment meet the filter replacement conditions.

[0160] In one embodiment, the control module is further configured to: when it is determined, based on the purification capacity detection data of each filter, that there are multiple candidate filters that do not meet the filter replacement conditions, determine the purification capacity value of each filter based on the purification capacity detection data of each filter; sort the purification capacity values ​​of each candidate filter in descending order, and determine the candidate filter corresponding to the maximum purification capacity value as the usable filter; determine the target rotation angle based on the position of the usable filter; and control the filter assembly to rotate based on the target rotation angle, rotating the usable filter to the air inlet.

[0161] In one embodiment, the purification capacity detection data includes the ambient dust concentration at the air inlet of the purification equipment and the purified dust concentration at the air outlet of the purification equipment. The control module is further configured to: determine the purification capacity value of the filter in use based on the concentration difference between the ambient dust concentration at the air inlet of the purification equipment and the purified dust concentration at the air outlet of the purification equipment; and determine that the filter in use meets the filter replacement conditions when the purification capacity value of the filter in use is less than or equal to a preset capacity threshold.
