[0036] The air processor provided by this invention allows air to enter the housing through the air inlet and flow along the first air duct inside the turbulence collector towards the air outlet. The smaller the particle size, the higher the irregularity of its motion. When the vortex blades rotate, small particles are more easily affected by the turbulence generated by the rotation of the vortex blades, while large particles, with greater inertia, are less easily disturbed by the vortex blades. Therefore, the velocity difference between small and large particles caused by turbulence intensifies collisions, causing small particles to aggregate onto large particles. Thus, the particles in the air flowing out of the first air duct outlet are primarily large particles. These particles are then intercepted and filtered by the first filter module, achieving purification. Therefore, this air processor can efficiently remove fine particles, resulting in excellent air purification. Attached Figure Description

[0050] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] Example

[0052] As living standards continue to improve, people's requirements for air quality are also gradually increasing, and air purifiers are being used more and more. Current air purifiers can typically filter out PM2.5 particles, but their removal rate for smaller particles such as PM1.0 is not high. PM1.0 can enter the alveoli of the lungs and is extremely harmful to human health.

[0053] Therefore, this embodiment provides an air processor.

[0054] In one implementation, such as Figures 1 to 7 As shown, the air processor includes a housing 1, a particulate turbulence coalescing module 2, and a first filter module 3. The housing 1 has an air inlet 101 and an air outlet 102. The particulate turbulence coalescing module 2 is disposed within the housing 1 and located in the airflow path from the air inlet 101 to the air outlet 102. The particulate turbulence coalescing module 2 includes at least one turbulence coalescer 201, and the turbulence coalescer 201 has several first air ducts 2011 inside, with rotatable vortex vanes 2012 inside the air ducts. The first filter module 3 is located downstream of the particulate turbulence coalescing module 2 in the airflow path from the air inlet 101 to the air outlet 102.

[0055] In this embodiment, such as Figure 2 As shown, air enters the housing 1 through the air inlet 101, as... Figure 4 and Figure 5 As shown, particles can flow along the first air duct 2011 inside the turbulence aggregator 201 towards the air outlet 102. The smaller the particle size, the higher the irregularity of the motion. When the vortex vane 2012 rotates, small particles are more easily affected by the turbulence generated by the rotation of the vortex vane 2012. Large particles have greater inertia and are less easily disturbed by the vortex vane 2012. Therefore, small particles are affected by turbulence and form a velocity difference with large particles, which intensifies the collision. Small particles aggregate onto large particles. Therefore, the particles in the air flowing out of the outlet of the first air duct 2011 are mainly large particles. When flowing through the first filter module 3, they are intercepted and filtered by the first filter module 3 to achieve purification. Therefore, this air processor can efficiently remove fine particles and has a good air purification effect.

[0056] In one specific implementation, the first filter module 3 is a HEPA filter, which can efficiently filter PM2.5 particles in the air and purify the air.

[0057] It should be noted that the outer casing 1 is equipped with a fan 4, which can accelerate the air flow and ensure that air continuously flows in from the air inlet 101 and flows out from the air outlet 102.

[0058] In one specific embodiment, the air outlet 102 is located on the top of the housing 1, and the top of the housing 1 is also provided with a display operation panel 5. The display operation panel 5 is located on one side of the air outlet 102, and the user can select the desired working mode through the display operation panel 5.

[0059] In one specific implementation, the first air duct 2011 is a circular air duct, and one or more vortex blades 2012 can be provided in each circular air duct.

[0060] Based on the above embodiments, in a preferred embodiment, a plurality of guide vanes 2013 are provided at the inlet of the first air duct 2011, and the guide vanes 2013 are used to guide air into the first air duct 2011. In this embodiment, the airflow can enter the first air duct 2011 more effectively after passing through the guide vanes 2013.

[0061] Based on the above embodiments, in a preferred embodiment, the particle turbulent agglomeration module 2 includes at least two turbulent agglomerators 201 connected in series. In this embodiment, by setting at least two turbulent agglomerators 201 connected in series, the efficiency of removing fine particles can be further improved when the vortex vanes 2012 in two or more turbulent agglomerators 201 are all rotating.

[0062] In one specific implementation, the first air ducts 2011 in two adjacent turbulence converging devices 201 are connected to each other, which means that the turbulence converging devices 201 are connected in series.

[0063] Based on the above embodiments, in a preferred embodiment, a PM1.0 sensor is provided at the air outlet 102, and the air processor also includes a controller. The controller is communicatively connected to the PM1.0 sensor and the first drive structure that drives the rotation of each vortex 2012, and is capable of: stopping the operation of at least one of the first drive structures of the turbulent aggregators 201 when the PM1.0 concentration detected by the PM1.0 sensor decreases and the rate of change of concentration decreases; and increasing the number of operating first drive structures of the turbulent aggregators 201 when the PM1.0 concentration detected by the PM1.0 sensor increases. In this embodiment, when the PM1.0 concentration detected by the PM1.0 sensor decreases and the rate of change of concentration decreases, it indicates that the air purification effect has basically reached its peak. At this time, the power of the air processor can be reduced by shutting down the first drive structure of at least one of the turbulent aggregators 201. When the PM1.0 concentration detected by the PM1.0 sensor increases, it indicates that the air quality is deteriorating, so the number of operating turbulent aggregators 201 increases to quickly purify the air.

[0064] Specifically, when the particle turbulence agglomeration module 2 includes two turbulence agglomerators 201 connected in series, when the PM1.0 concentration detected by the PM1.0 sensor decreases and the rate of change of concentration decreases, the first drive structure of one of the turbulence agglomerators 201 is controlled to stop working; when the PM1.0 concentration detected by the PM1.0 sensor increases, the first drive structures of both turbulence agglomerators 201 are controlled to work simultaneously.

[0065] In one specific implementation, the processor of the air processor records the PM1.0 sensor value d at the sequential air outlet 102 every half minute. The concentration change rate is the current PM1.0 sensor value d1 minus the value d2 after half a minute, divided by 30 seconds, i.e. (d1-d2) / 30.

[0066] Based on the above embodiments, in a preferred embodiment, the particulate turbulence coalescing module 2 further includes a second air duct 202 disposed on one side of the turbulence coalescer 201. The particulate turbulence coalescing module 2 is rotatably disposed in the housing 1, so that air entering from the air inlet 101 can selectively pass through the first air duct 2011 or the second air duct 202. In this embodiment, by rotatably disposing of the particulate turbulence coalescing module 2 in the housing 1, when the PM1.0 concentration is very low, the turbulence coalescer 201 does not operate, and the second air duct 202 is located on the airflow path from the air inlet 101 to the air outlet 102. When the PM1.0 concentration is high, the turbulence coalescer 201 is located on the airflow path from the air inlet 101 to the air outlet 102, thus meeting different user needs.

[0067] like Figure 3 As shown, the turbulence coalescing module includes a semi-circular first support 203 and a second support 204. A turbulence coalescer 201 is disposed within the first support 203. The inner side of the second support 204 forms a second air duct 202. Both the first support 203 and the second support 204 are retractable within the outer casing 1. In this embodiment, by retracting both the first support 203 and the second support 204 within the outer casing 1, the user can remove the first support 203 and the second support 204 to clean or replace their internal structures in the event of a power outage.

[0068] Further reference Figure 3The outer casing 1 contains a rotatable first crossbeam 205, on which an electromagnet 6 is mounted. The electromagnet 6 can generate a magnetic attraction force on the first bracket 203 and the second bracket 204. In this embodiment, when the air processor is in operation, the electromagnet 6 is activated, attracting the first bracket 203 and the second bracket 204 to the first crossbeam 205, preventing the user from removing them. When the air processor is off, the electromagnet 6 loses its magnetic attraction force, allowing the user to pull out the first bracket 203 and the second bracket 204 for cleaning or replacement of their internal structures. This embodiment ensures the safe use of the air processor.

[0069] In one specific embodiment, the outer casing 1 is provided with a second driving structure, which is connected to the first crossbeam 205 and can drive the first crossbeam 205 to rotate. The rotation of the first crossbeam 205 can drive the first bracket 203 and the second bracket 204 to rotate synchronously.

[0070] In one specific implementation, the controller is communicatively connected to the PM1.0 sensor and the second drive structure, and can automatically control the rotation of the particulate turbulence coalescence module 2.

[0071] Based on the above embodiments, in a preferred embodiment, the air processor further includes a second filter module 7 disposed in the housing 1. The second filter module 7 is located on the side of the particulate turbulence coalescing module 2 near the air inlet 101, and includes a primary filter. In this embodiment, the second filter module 7 can filter out larger particles, dust, hair, etc., preventing larger particles, dust, hair, etc. from entering the first air duct 2011 and causing blockage of the first air duct 2011.

[0072] In one specific embodiment, the primary filter is a plastic mesh made of woven PET.

[0073] Based on the above embodiments, in a preferred embodiment, the primary filter includes a first semi-circular filter 701 and a second semi-circular filter 702. The second filter module 7 also includes a water nozzle 703 for spraying water onto the first semi-circular filter 701. The second filter module 7 is rotatably disposed in the housing 1 so that air entering from the air inlet 101 can selectively pass through either the first semi-circular filter 701 or the second semi-circular filter 702. In this embodiment, by rotatably disposing of the second filter module 7 in the housing 1, when the turbulence agglomerator 201 is required, the second filter module 7 can be rotated to a position where air entering from the air inlet 101 passes through the first semi-circular filter 701. While filtering larger particles, dust, and hair, the water nozzle 703 sprays water toward the first semi-circular filter 701 to humidify the air, increasing the air humidity. This makes it easier for particles to agglomerate due to the adhesive force of water, improving the removal effect of fine particles. When the turbulence aggregator 201 is not needed, the second filter module 7 can be rotated to a position where the air entering from the air inlet 101 passes through the second semi-circular filter screen 702, and the second filter module 7 only serves a filtering function.

[0074] Based on the above embodiments, in a preferred embodiment, the first semi-circular filter 701 is disposed in the semi-circular third bracket 704, the second semi-circular filter 702 is disposed in the semi-circular fourth bracket 705, and the water nozzle 703 is disposed on the third bracket 704. Both the third bracket 704 and the fourth bracket 705 are retractable within the outer casing 1. In this embodiment, by making both the third bracket 704 and the fourth bracket 705 retractable within the outer casing 1, in the event of a power outage, the user can pull out the third bracket 704 and the fourth bracket 705 to clean or replace their internal structures.

[0075] Based on the above embodiments, in a preferred embodiment, a second crossbeam 706 is rotatably provided inside the outer casing 1. An electromagnet 6 is mounted on the second crossbeam 706, which can generate a magnetic attraction force on the third bracket 704 and the fourth bracket 705. In this embodiment, when the air processor is in operation, the electromagnet 6 activates, attracting the third bracket 704 and the fourth bracket 705 to the second crossbeam 706, preventing the user from removing them. When the air processor is off, the electromagnet 6 loses its magnetic attraction force, allowing the user to pull out the third bracket 704 and the fourth bracket 705 for cleaning or replacement of their internal structures. This embodiment ensures the safe use of the air processor.

[0076] In one specific embodiment, the outer casing 1 is provided with a third driving structure, which is connected to the second crossbeam 706 and can drive the second crossbeam 706 to rotate. The rotation of the second crossbeam 706 can drive the third bracket 704 and the fourth bracket 705 to rotate synchronously.

[0077] In one specific implementation, the controller is communicatively connected to the third drive structure to control the automatic rotation of the second filter module 7.

[0078] Based on the above embodiments, in a preferred embodiment, the outer casing 1 is further provided with a dust collection tray 8, which is located below the second filter module 7. In this embodiment, since the primary filter can block larger particles, dust, and hair, the larger particles, dust, and hair blocked by the primary filter can fall onto the dust collection tray 8, and the user only needs to clean the dust collection tray 8 periodically.

[0079] In a preferred embodiment, the ash tray 8 is removably disposed within the housing 1 for easy cleaning.

[0080] Based on the above embodiments, in a preferred embodiment, a water tank 9 is further provided inside the outer casing 1, and the water tank 9 is located below the ash receiving tray 8. In this embodiment, since the second filter module 7 includes a water nozzle 703 for spraying water onto the first semi-circular filter screen 701, the water falling from the first semi-circular filter screen 701 can be collected in the water tank 9, and the water tank 9 can supply water to the water nozzle 703.

[0081] Based on the above embodiments, in a preferred embodiment, the air processor further includes a humidity control module 10. The humidity control module 10 is located on the side of the particulate turbulence coalescing module 2 opposite to the second filter module 7. The humidity control module 10 includes a humidification channel 1001 and a drying channel 1002. The humidity control module 10 is rotatably disposed within the housing 1, allowing air flowing from the particulate turbulence coalescing module 2 to selectively pass through either the humidification channel 1001 or the drying channel 1002. In this embodiment, by providing a humidity control module 10 rotatably disposed within the housing 1, when air humidification is required, the air flowing from the particulate turbulence coalescing module 2 is humidified through the humidification channel 1001; when air drying is required, the air flowing from the particulate turbulence coalescing module 2 is dried through the drying channel 1002. Therefore, different user needs can be met.

[0082] Based on the above embodiments, in a preferred embodiment, the humidity control module 10 includes a semi-circular fifth bracket 1003 and a sixth bracket 1004. The fifth bracket 1003 contains a desiccant tray 1005, on which solid silica gel 1006 is disposed. The sixth bracket 1004 contains a humidifying water vapor channel 1007. In this embodiment, when air flows through the inner side of the fifth bracket 1003, the solid silica gel 1006 dries the air after it has passed through the particle turbulence coalescence module 2. When air flows through the inner side of the sixth bracket 1004, the humidifying water vapor channel 1007 sprays water mist into the inner side of the sixth bracket 1004 to humidify the air.

[0083] In one specific embodiment, an ultrasonic atomizer is provided near the water tank 9, and the water mist generated by the ultrasonic atomizer can be transported to the humidifying water vapor channel 1007 through a pipeline.

[0084] Based on the above embodiments, in a preferred embodiment, both the fifth bracket 1003 and the sixth bracket 1004 are retractable within the housing 1. In this embodiment, by retracting both the fifth bracket 1003 and the sixth bracket 1004 within the housing 1, in the event of a power outage, the user can pull out the fifth bracket 1003 and the sixth bracket 1004 to clean or replace their internal structures.

[0085] Based on the above embodiments, in a preferred embodiment, a third crossbeam 1008 is rotatably provided inside the outer casing 1. An electromagnet 6 is installed on the third crossbeam 1008, which can generate a magnetic attraction force on the fifth bracket 1003 and the sixth bracket 1004. In this embodiment, when the air processor is in operation, the electromagnet 6 activates, attracting the fifth bracket 1003 and the sixth bracket 1004 to the third crossbeam 1008, preventing the user from removing them. When the air processor is in the off state, the electromagnet 6 loses its magnetic attraction force, allowing the user to pull out the fifth bracket 1003 and the sixth bracket 1004 for cleaning or replacement of their internal structures. This embodiment ensures the safe use of the air processor.

[0086] In one specific embodiment, the outer casing 1 is provided with a fourth driving structure, which is connected to the third crossbeam 1008 and can drive the third crossbeam 1008 to rotate. The rotation of the third crossbeam 1008 can drive the fifth bracket 1003 and the sixth bracket 1004 to rotate synchronously.

[0087] In one specific implementation, the controller is communicatively connected to the fourth drive structure to control the humidity regulation module 10 to rotate automatically.

[0088] In this embodiment, when the user selects a humidification mode and sets the humidity, and the current air quality requires the turbulence aggregator 201 to be activated, the second filter module 7 rotates to allow air to flow through the first semi-circular filter 701, and the particle turbulence aggregator module 2 switches to a two-aggregator series connection. The humidity control module 10, based on data from the humidity sensor, switches the humidification channel 1001 and the drying channel 1002 in real time to ensure the current ambient humidity is at the user-set humidity level. When the user selects a humidification mode and sets the humidity, and the current air quality does not require the turbulence aggregator 201 to be activated, the second filter module 7 switches to allow air to flow through the second semi-circular filter 702, and the particle turbulence aggregator module 2 switches to allow air to flow through the second air duct 202. The dehumidification module, based on data from the humidity sensor, switches the humidification channel 1001 and the drying channel 1002 in real time to ensure the current ambient humidity is at the user-set humidity level. When the user does not select humidification and the current air quality requires the turbulence aggregator 201 to be turned on, the second filter module 7 switches to allow air to flow through the first semi-circular filter 701, the particle turbulence aggregator module 2 switches to two aggregators connected in series, and the humidity adjustment module 10 switches to allow air to flow through the drying channel 1002.

[0089] Specifically, such as Figure 2 As shown, the air processor has a baffle directly opposite the air inlet 101. The area of ​​the baffle near the air inlet is the air intake area. After the air enters the air intake area, it is blocked by the baffle and cannot flow to the other side, so it can only flow upward.

[0090] The second filter module 7 is adjacent to the air inlet area. When the first semi-circular filter 701 is located on the left side, that is, directly opposite the air inlet area, the air can only flow through the first semi-circular filter 701 due to the obstruction of the second crossbeam 706 in the middle of the second filter module 7. In other words, the first semi-circular filter 701 is located on the air flow path from the air inlet 101 to the air outlet 102. When the second semi-circular filter 702 is directly opposite the air inlet area, the air can only flow through the second semi-circular filter 702 due to the obstruction of the second crossbeam 706 in the middle of the second filter module 7. In other words, the second semi-circular filter 702 is located on the air flow path from the air inlet 101 to the air outlet 102.

[0091] The particulate turbulence coalescing module 2 is located directly above and adjacent to the second filter module 7. When the turbulence coalescing device 201 is located on the left, the air can only flow through the turbulence coalescing device 201 due to the obstruction of the first crossbeam 205 in the middle of the particulate turbulence coalescing module 2. That is, the first air duct 2011 is located on the air flow path from the air inlet 101 to the air outlet 102. When the second air duct 202 is located on the left, the air can only flow through the second air duct 202 due to the obstruction of the first crossbeam 205 in the middle of the particulate turbulence coalescing module 2. That is, the second air duct 202 is located on the air flow path from the air inlet 101 to the air outlet 102.

[0092] The humidity control module 10 is located directly above and adjacent to the particulate turbulence coalescence module 2. When the humidification channel 1001 is located on the left, it is blocked by the third crossbeam 1008 in the middle of the humidity control module 10, so the air can only flow through the humidification channel 1001. That is, the humidification channel 1001 is located on the air flow path from the air inlet 101 to the air outlet 102. When the drying channel 1002 is located on the left, it is blocked by the third crossbeam 1008 in the middle of the humidity control module 10, so the air can only flow through the drying channel 1002. That is, the drying channel 1002 is located on the air flow path from the air inlet 101 to the air outlet 102.

[0093] This embodiment also provides a control method for an air processor, which is applied to the air processor described above.

[0094] In one implementation, the control method includes the following steps:

[0095] S1. Obtain the concentration and concentration change rate of PM1.0. Specifically, a PM1.0 sensor is installed at the air outlet 102. The concentration of PM1.0 can be obtained through the PM1.0 sensor, and the concentration change rate can be calculated based on the obtained PM1.0 concentration. More specifically, the air processor records the PM1.0 sensor value d at the air outlet 102 every half minute. The concentration change rate is the current PM1.0 sensor value d1 minus the value d2 after half a minute, divided by 30 seconds, i.e., (d1-d2) / 30.

[0096] S2. Adjust the number of operating first drive structures of the turbulence aggregator 201 based on the PM1.0 concentration and its rate of change. Specifically, when the PM1.0 concentration detected by the PM1.0 sensor decreases and the rate of change of concentration decreases, it indicates that the air purification effect has basically reached its peak. At this time, the power of the air processor can be reduced by turning off the first drive structure of at least one of the turbulence aggregators 201. When the PM1.0 concentration detected by the PM1.0 sensor increases, it indicates that the air quality is deteriorating. Therefore, the number of operating turbulence aggregators 201 is increased to quickly purify the air.

[0097] Based on the above embodiments, in a preferred embodiment, the control method further includes the following steps:

[0098] S3. Determine whether the concentration of PM1.0 is lower than the first preset value. Specifically, a PM1.0 sensor is installed at the air outlet 102, and the concentration of PM1.0 can be obtained through the PM1.0 sensor.

[0099] S4. If so, control the particle turbulence coalescing module 2 to rotate so that the second air duct 202 is located on the air flow path from the air inlet 101 to the air outlet 102. Specifically, when the concentration of PM1.0 is lower than the first preset value, it means that the concentration of PM1.0 is very low, and there is no need to operate the turbulence coalescing device 201. Therefore, positioning the second air duct 202 on the air flow path from the air inlet 101 to the air outlet 102 can make the air flow quickly.

[0100] S5. If not, control the particle turbulence coalescing module 2 to rotate so that the first air duct 2011 is located on the air flow path from the air inlet 101 to the air outlet 102. Specifically, when the concentration of PM1.0 is equal to or higher than the first preset value, it indicates that the concentration of PM1.0 is high, and the turbulence coalescing device 201 needs to be activated.

[0101] This implementation method can avoid unnecessary operation of the turbulence cohesive device 201, achieving energy saving and high efficiency.

[0102] Based on the above embodiments, in a preferred embodiment, the control method further includes the following steps:

[0103] S6. If the concentration of PM1.0 is equal to or higher than the first preset value, control the second filter module 7 to rotate so that the first semi-circular filter screen 701 is located on the air flow path from the air inlet 101 to the air outlet 102. Specifically, when the concentration of PM1.0 is equal to or higher than the first preset value, it indicates that the concentration of PM1.0 is high, and the turbulence agglomerator 201 needs to be activated. At the same time, the second filter module 7 is rotated so that the first semi-circular filter screen 701 is located on the air flow path from the air inlet 101 to the air outlet 102. While filtering larger particles, dust, and hair, the water nozzle 703 sprays water toward the first semi-circular filter screen 701 to humidify the air, increasing the air humidity. The particles will more easily agglomerate together due to the adhesion of water, improving the effect of removing fine particles.

[0104] Based on the above embodiments, in a preferred embodiment, the control method further includes the following steps:

[0105] S7. Obtain air humidity. Specifically, air humidity can be obtained through a humidity sensor.

[0106] S8. Determine whether the air humidity is lower than the second preset value.

[0107] S9. If so, the humidity control module 10 is rotated so that the humidification channel 1001 is located on the air flow path from the air inlet 101 to the air outlet 102. Specifically, when the air humidity is lower than the second preset value, it indicates that the air humidity is low and the humidification function needs to be used. Therefore, the humidity control module 10 is rotated so that the humidification channel 1001 is located on the air flow path from the air inlet 101 to the air outlet 102, and the air flowing out from the particle turbulence coalescence module 2 is humidified through the humidification channel 1001.

[0108] S10. If not, control the humidity adjustment module 10 to rotate so that the drying channel 1002 is located on the air flow path from the air inlet 101 to the air outlet 102. Specifically, if the air humidity is higher than or equal to the second preset value, it means that the air humidity is high and there is no need to use the humidification function. However, when the air first flows through the first semi-circular filter 701 and is humidified, it is necessary to control the humidity adjustment module 10 to rotate so that the drying channel 1002 is located on the air flow path from the air inlet 101 to the air outlet 102 to dry the humidified air.

[0109] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
