Detailed Description

To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1, an operation control method of a repeller assembly for a dust collecting apparatus of an air cleaner includes steps S100, S200, and S300.

And S100, acquiring an air inlet fine particulate matter concentration value at an air inlet of the air purifier and an air outlet fine particulate matter concentration value at an air outlet of the air purifier.

Specifically, the fine particulate matter is also called fine particles, and PM2.5, and the fine particulate matter refers to particulate matter having an aerodynamic equivalent diameter of 2.5 μm or less in ambient air. It can be suspended in air for a long time, and the higher the content concentration in the air, the more serious the air pollution is. Air purifier except that the front end is used for carrying out prefilter's primary filter net to the air to and be used for carrying out the ionization to the air and purify the subassembly, still be provided with integrated device and carry out the collection of dust or particulate matter in the place that is close to the air outlet. The integrated device generally includes a repeller, an integrator, and a dust-collecting plate disposed between the repeller and the integrator, and an electric field between the repeller and the integrator causes the particles to adhere to the dust-collecting plate to achieve collection.

The application provides a repeller subassembly includes air intake particulate matter detector, switching device, controller and is used for forming the electric field and carries out the wire electrode that particulate matter collected. The air inlet particle detector is arranged at an air inlet of the air purifier and used for detecting the content of particles in air at the air inlet of the air purifier, namely the concentration value of fine particles at the air inlet; and the air outlet particulate matter detector is arranged at the air outlet of the air purifier and is used for detecting the content of particulate matters in the air (purified air) at the air outlet of the air purifier, namely the concentration value of the fine particulate matters at the air outlet. The air inlet particle detector detects an air inlet fine particle concentration value and sends the air inlet fine particle concentration value to the controller, and the air outlet particle detector detects an air outlet fine particle concentration value and sends the air outlet fine particle concentration value to the controller, namely, the controller is represented to acquire the air inlet fine particle concentration value and the air outlet fine particle concentration value.

It should be noted that the specific types of the air inlet particle detector and the air outlet particle detector are not exclusive, as long as the detection of the concentration value of the fine particles at the corresponding positions can be realized. For example, in one more detailed embodiment, the inlet particulate matter detector and the outlet particulate matter detector are both PM2.5 sensors.

And step S200, obtaining the clean state grade information of the purified environment according to the concentration value of the fine particles at the air inlet and the concentration value of the fine particles at the air outlet.

Specifically, the cleanliness state level information of the purified environment represents air quality information after the purified environment is purified by the air purifier. A higher information of the cleanliness status level indicates a cleaner decontamination environment, i.e. a better control quality of the decontamination environment. After the controller obtains the concentration value of the fine particulate matters at the air inlet and the concentration value of the fine particulate matters at the air outlet, the controller can combine the concentration values to analyze, and clean state grade information of the purified environment can be obtained according to the change of the concentration values of the fine particulate matters before and after purification and the like.

It should be noted that the cleaning state grade information is not particularly unique, and the cleaning state grade information may be differentiated according to an actual use scene or a model of the air purifier, and may be cleaning state grade information in which two grades, three grades, four grades, or even more grades are set. For example, in a more detailed embodiment, three levels of cleaning status information may be set, specifically a low cleaning status, a medium cleaning status, and a high cleaning status, wherein the high cleaning status corresponds to a best air quality of the clean environment.

And step S300, controlling the corresponding number of electrode wires in the repeller assembly to be connected with a power supply to operate according to the grade information of the cleaning state.

Specifically, when the controller performs comparative analysis by combining the concentration value of the fine particulate matters at the air inlet and the concentration value of the fine particulate matters at the air outlet to obtain the grade information of the cleaning state, the matched number of the electrode wires are controlled to be connected to the power supply to operate according to the grade information of the cleaning state. Through this kind of control scheme, can avoid the condition that the wire electrode all inserts the operation to take place among the whole operation process, take place to repel utmost point and strike sparks relatively when all wire electrodes all insert the operation, take place to repel under this state of striking sparks when the less wire electrode of quantity inserts the operation, the degree of repelling utmost point and striking sparks is lower, and the crackle sound that sends is also less to experience for the better use of user. Meanwhile, the generation amount of ozone can be reasonably adjusted by matching the access quantity control of the wire electrodes with the grade of the cleaning state, and the stable and energy-saving self-adaptive working state is achieved.

It can be understood that the mode that the controller controls whether the electrode wire is connected to the power supply for operation is not unique, and in one embodiment, different power supplies can be respectively connected to different electrode wires, and then the connection and disconnection operations of the corresponding electrode wires can be realized only by controlling the on or off of the power supplies. In another embodiment, a switch device can be connected between the wire electrode and the power supply, and whether the wire electrode is connected with the power supply or not can be controlled by switching on and off of the switch device. Further, in one embodiment, the device may be switched only between a part of the electrode wires and the power supply, and the number of the electrode wires connected to the power supply may be changed by controlling the number of the part of the electrode wires connected to the power supply.

Referring to fig. 2, in one embodiment, step S200 includes step S210 and step S220.

Step S210, determining whether the concentration value of the fine particles at the air outlet is less than or equal to a first preset concentration threshold, and whether the difference between the concentration value of the fine particles at the air inlet and the concentration value of the fine particles at the air outlet is less than or equal to a preset difference threshold. Step S220, if the concentration value of the fine particulate matters at the air outlet is greater than a first preset concentration threshold value, and/or the difference value is greater than a preset difference value threshold value, the purified environment is in a low-grade clean state.

Specifically, according to the scheme of the embodiment, when the cleaning state grade analysis is performed, the purified air quality and the air purification capacity are combined for analysis, that is, the difference between the concentration value of the fine particles in the air inlet and the concentration value of the fine particles in the air outlet is obtained. Firstly, the concentration value of the fine particulate matters at the air outlet is compared and analyzed with a first preset concentration threshold value, if the concentration value of the fine particulate matters at the air outlet is larger than the first preset concentration threshold value, the concentration of the fine particulate matters in the purified air is still higher, and at the moment, information that the purification environment is in a low-grade clean state is obtained. Similarly, when the difference between the concentration value of the fine particulate matters at the air inlet and the concentration value of the fine particulate matters at the air outlet is greater than the preset difference threshold, the air purifier has insufficient purification capacity for the inflowing air, the concentration of the fine particulate matters is still high after the inflowing air is purified, and the information that the purified environment is in a low-grade clean state can be obtained at the moment.

It should be noted that the first predetermined concentration threshold and the predetermined difference threshold are not unique in magnitude, and in a more detailed embodiment, the first predetermined concentration threshold may be set to 10 micrograms per cubic meter and the predetermined difference threshold may be set to 5 micrograms per cubic meter. In other embodiments, the first preset concentration threshold value and the preset difference threshold value can be set to other values according to actual conditions.

Referring to fig. 3, in an embodiment, after step S210, the method further includes step S230 and step S240.

Step S230, if the concentration value of the fine particulate at the air outlet is less than or equal to the first preset concentration threshold and the difference value is less than or equal to the preset difference threshold, determining whether the concentration value of the fine particulate at the air outlet is less than or equal to the second preset concentration threshold and the difference value is less than or equal to the preset difference threshold. Step S240, if the concentration value of the fine particles at the air outlet is less than or equal to a second preset concentration threshold, and the difference value is less than or equal to a preset difference threshold, the high-cleanness state of the purified environment is obtained.

Specifically, the second preset density threshold is smaller than the second preset density threshold. Referring to fig. 4, after obtaining the concentration values of the fine particles at the inlet and the outlet, the controller first compares the concentration value of the fine particles at the outlet with a first predetermined concentration threshold, and compares the difference between the two with a predetermined difference threshold. If the concentration value of the fine particulate matters at the air outlet is smaller than or equal to a first preset concentration threshold value and the difference value is smaller than or equal to a preset difference threshold value, a second preset concentration threshold value smaller than the first preset concentration threshold value needs to be combined for analysis, and whether the concentration value of the fine particulate matters at the air outlet is smaller than or equal to the second preset concentration threshold value and the difference value is smaller than or equal to the preset difference threshold value are simultaneously met is judged. If the concentration value of the fine particulate matters in the air outlet is smaller than or equal to the second preset concentration threshold value, and the difference value is smaller than or equal to the preset difference value threshold value, it is indicated that the concentration of the fine particulate matters in the purified air is very low, the purifying capacity of the air purifier is high, and information that the purifying environment is in a high clean state is obtained.

Likewise, the magnitude of the second preset density threshold is not exclusive, as long as it is less than the first preset density threshold. For example, in a more detailed embodiment, the second preset concentration threshold may be set at 5 micrograms per cubic meter.

It should be noted that since the air quality will gradually become better as the air purifier is operated, the fine particulate matter concentration will gradually decrease. Therefore, in an embodiment, referring to fig. 4, when the controller detects that the concentration value of the fine particulate matters at the air outlet is greater than the first preset concentration threshold, and/or after the concentration value of the fine particulate matters at the air outlet is greater than the preset difference threshold, and controls the corresponding number of the electrode wires in the repeller assembly to be connected to the power supply to operate, the detection operation of whether the concentration value of the fine particulate matters at the air outlet is less than or equal to the first preset concentration threshold and whether the difference value is less than or equal to the preset difference threshold is performed again, so as to ensure that the concentration value of the fine particulate matters at the air outlet is changed, so that the cleaning level of the current cleaning environment can be obtained in time when the concentration value of the fine particulate matters at the air outlet is changed.

Referring to fig. 3, in an embodiment, after step S230, the method further includes step S250. Step S250, if the concentration value of the fine particles at the air outlet is greater than a second preset concentration threshold value and less than or equal to a first preset concentration threshold value, and/or the difference value is greater than a preset difference value threshold value, the purified environment is in a medium clean state.

Specifically, when further analyzing whether the concentration value of the fine particulate matters at the air outlet is smaller than or equal to a second preset concentration threshold value and whether the difference value is smaller than or equal to a preset difference threshold value, the condition of no further occurs. At the moment, the concentration value of the fine particles at the air outlet is larger than a second preset concentration threshold value, and/or the difference value is larger than a preset difference value threshold value, the controller can obtain the information that the purified environment is in a medium cleaning state, and the purified environment is between the high cleaning state and the low cleaning state. Because the detection of the concentration value of the fine particulate matters at the air outlet is carried out under the condition that the concentration value of the fine particulate matters at the air outlet is less than or equal to the first preset concentration threshold value, the concentration value of the fine particulate matters at the air outlet is greater than the second preset concentration threshold value and is less than or equal to the first preset concentration threshold value.

Also, since the air quality will gradually become better as the air purifier is operated, the fine particulate matter concentration will gradually decrease. In an embodiment, referring to fig. 4, when the controller detects that the cleaning level is in the intermediate cleaning state, and controls the corresponding number of the electrode wires in the repeller assembly to be connected to the power supply to operate, the controller further detects whether the concentration value of the fine particles at the air outlet is less than or equal to a second preset concentration threshold value, and whether the difference value is less than or equal to a preset difference threshold value, so that the detection can be performed in time when the cleaning level of the cleaning environment changes.

Referring to fig. 5, in one embodiment, step S300 includes step S310, step S320, and step S330.

Step S310, when the purification environment is in a low-grade clean state, controlling a first number of electrode wires in the repeller assembly to be connected to a power supply for operation; step S320, when the purification environment is in a medium cleaning state, controlling a second number of electrode wires in the repeller assembly to be connected to a power supply for operation; and step S330, controlling the third number of electrode wires in the repeller assembly to be connected to a power supply to operate when the purification environment is in a high-level cleaning state.

Specifically, the first number is greater than the second number, which is greater than the third number. In the scheme of the embodiment, the number of the wire electrodes which are connected with the power supply and participate in the air purification operation in the rejection assembly is different according to different cleaning state grades. When the purification environment is in a high-grade clean state, the air quality in the environment is very good, and the concentration of pollutants such as fine particles is very low, so that the dust collection requirement can be met only by connecting a small number of electrode wires of the repeller component into operation. When the clean environment is in the medium clean state, the air quality is better in the environment, and the concentration of pollutants such as fine particles is lower, consequently, need be more than the electrode wire access operation of quantity under the high clean state, just can satisfy the collection dirt demand. When purifying the environment and being in low clean state, air quality is relatively poor in the environment, and the concentration of pollutants such as fine particles is higher, consequently, need be more than the electrode wire access operation of quantity under the medium clean state, just can satisfy the collection dirt demand.

It should be noted that the first number, the second number and the third number are not exclusive, and may be different according to the arrangement mode and the arrangement number of the electrode wires in the actual repeller assembly. For example, in a more detailed embodiment, the repeller assembly has 15 wires disposed therein, and is arranged in three layers, each layer having five wires, which are numbered 1, 2, 3, 4, and 5. When the purification environment is in a high-grade clean state, the controller controls the wire electrodes marked with the numbers 2 and 4 in the layers 1, 2 and 3 to be disconnected to work, namely the third number is 9; when the purification environment is in a medium cleaning state, the controller controls the two layers of wire electrodes with the labels 2 and 4 to be disconnected to work, namely the second quantity is 11; and when the purification environment is in a low-grade clean state, all the electrode wires are switched in to operate, namely the first number is 15.

In one embodiment, the operation control method further includes: when a shutdown command is received, the power supply is turned off to interrupt the operation of all the electrode wires in the repeller assembly.

Specifically, referring to fig. 4, no matter what operation state the controller analyzes according to the concentration value of the fine particulate matters at the air inlet and the concentration value of the fine particulate matters at the air outlet, the controller detects whether the shutdown instruction is received in real time, as long as the shutdown instruction is detected, the air purifier corresponding to the repeller assembly is shut down, and at this time, the corresponding controller interrupts the operation of each wire electrode.

According to the operation control method of the repeller component, in the operation process, the concentration value of fine particulate matters at the air inlet of the air purifier and the concentration value of fine particulate matters at the air outlet of the air purifier can be acquired and analyzed to obtain the grade information of the cleaning state of the environment purified by the air purifier in the current operation state, and then the corresponding number of electrode wires in the repeller component are controlled to be connected to the power supply to operate according to the different grade information of the cleaning state. Through above-mentioned scheme, the actual access condition of wire electrode in the repeller subassembly can change along with the clean state difference of purifying environment, need not keep all wire electrodes all to insert the state of operation to reduce the phenomenon that the repeller struck sparks to a certain extent, crack when reducing the repeller struck sparks. Meanwhile, the quantity of the electrode wires connected to the power supply for operation is adjusted to be matched with the purification environment, so that the generation quantity of ozone can be reasonably controlled, and the phenomenon that additional products such as ozone overflow is avoided.

Referring to fig. 6, a repeller assembly includes: a switching device 40; the air inlet particle detector 10 is arranged at an air inlet of the air purifier and is used for detecting the concentration value of fine particles at the air inlet; an air outlet particle detector 20, disposed at an air outlet of the air purifier, for detecting a concentration value of fine particles at the air outlet; wire electrodes 50, each wire electrode 50 being connected to a power supply, wherein at least one wire electrode 50 is connected to the power supply through the switching device 40; the controller 30, the air inlet particle detector 10, the air outlet particle detector 20 and the switch device 40 are respectively connected with the controller 30, and the controller 30 is used for controlling the corresponding number of the electrode wires 50 to be connected with a power supply to operate according to the operation control method.

Specifically, the air purifier is provided with an integrated device for collecting dust or particulate matters in a place close to the air outlet, except for a primary filter screen for primarily filtering the air at the front end and an ionization purification component for ionizing and purifying the air. The integrated device generally includes a repeller, an integrator, and a dust-collecting plate disposed between the repeller and the integrator, and an electric field between the repeller and the integrator causes the particles to adhere to the dust-collecting plate to achieve collection.

The repeller assembly provided by this embodiment includes an air inlet particulate matter detector 10, a switching device 40, a controller 30, and a wire electrode 50 for creating an electric field for particulate matter collection. The air inlet particulate matter detector 10 is arranged at an air inlet of the air purifier and is used for detecting the content of particulate matters in air at the air inlet of the air purifier, namely the concentration value of fine particulate matters at the air inlet; the air outlet particle detector 20 is disposed at an air outlet of the air purifier, and is configured to detect a content of particles in air (purified air) at the air outlet of the air purifier, that is, a concentration value of fine particles at the air outlet. Air intake particulate matter detector 10 detects air intake fine particulate matter concentration value and sends controller 30, and air outlet particulate matter detector 20 detects air outlet fine particulate matter concentration value and sends controller 30, and characterization controller 30 acquires air intake fine particulate matter concentration value and air outlet fine particulate matter concentration value promptly.

It should be noted that the specific types of the inlet particle detector 10 and the outlet particle detector 20 are not exclusive, as long as the detection of the concentration value of the fine particles at the corresponding positions can be achieved. For example, in one more detailed embodiment, the inlet particulate matter detector 10 and the outlet particulate matter detector 20 are both PM2.5 sensors.

The cleanliness state level information of the purified environment represents air quality information after the purified environment is purified by the air purifier. A higher information of the cleanliness status level indicates a cleaner decontamination environment, i.e. a better control quality of the decontamination environment. After the controller 30 obtains the concentration value of the fine particulate matters at the air inlet and the concentration value of the fine particulate matters at the air outlet, the concentration values are combined to analyze, and the clean state grade information of the purified environment is obtained according to the change of the concentration values of the fine particulate matters before and after purification and the like.

When the controller 30 performs comparative analysis by combining the concentration value of the fine particulate matters at the air inlet and the concentration value of the fine particulate matters at the air outlet to obtain the grade information of the cleaning state, the electrode wires 50 with the matched number are controlled to be connected to the power supply to operate according to the grade information of the cleaning state. Through this kind of control scheme, can avoid the condition that whole operation in-process wire electrode 50 all inserts the operation to take place, take place the repulsion utmost point when all wire electrodes 50 all insert the operation and strike sparks relatively, and the less wire electrode 50 of quantity takes place under this state of repelling utmost point striking sparks when inserting the operation, and the degree of repelling utmost point striking sparks is lower, and the crackle that sends is also less to experience for the better use of user. Meanwhile, the generation amount of ozone can be reasonably adjusted by matching the access quantity control of the wire electrode 50 with the grade of the cleaning state, so that the stable and energy-saving self-adaptive working state is achieved.

In the scheme of the embodiment, the control of whether the wire electrode 50 is connected to the power supply is realized by switching on and off the switching device 40. The switch device 40 may be connected between each wire electrode 50 and the power supply, and whether the wire electrode 50 is connected to the power supply or not may be controlled by turning on and off the switch device 40. The number of the electrode wires 50 connected to the power supply can be changed by only controlling the number of the electrode wires 50 connected to the power supply by switching the device 40 between a part of the electrode wires 50 and the power supply.

In one embodiment, the switching device 40 is a relay switch.

Specifically, the specific type of the switching device 40 is not exclusive, and the switching device can be controlled to switch on or off the corresponding wire electrode 50. In the solution of this embodiment, a relay switch is specifically used to control whether the wire electrode 50 is connected to the power supply. According to the scheme of the embodiment, the relay can generate magnetic force to attract in the power-on state, and the magnetic force disappears in the power-off state, and accordingly the relay does not have attraction capacity, so that whether the wire electrode 50 is connected to the power supply or not is controlled.

It should be noted that the specific structure of the relay switch is not exclusive, and in an embodiment, please refer to fig. 7, the relay switch includes a relay 42, a metal-based switch 44, a base 41, a support 43, a structural member 45 and a high voltage connection pole 46, the relay 42 and the support 43 are disposed on the same surface of the base 41, the metal-based switch 44 is movably connected to the support 43 and located at one end of the relay 42 away from the base 41, the high voltage connection pole 46 is connected to a power supply, and the wire electrode 50 is connected to the structural member 45; the relay 42 is connected to the controller 30 (not shown), when the relay 42 is not energized, the structure 45 and the high voltage connection pole 46 are connected by the metal-based switch 44, and when the relay 42 is energized, the metal-based switch 44 is engaged to disconnect the structure 45 from the high voltage connection pole 46.

Specifically, in the relay switch provided in this embodiment, the relay 42 is disposed on the base 41, and meanwhile, the metal-based switch 44 is movably connected to the supporting member 43, and is disposed at one end of the relay 42 away from the base 41 through the supporting member 43, that is, the top of the relay 42 shown in the figure, so that when the relay 42 is powered on, the metal-based switch 44 can be attracted. The power supply is connected through the high-voltage connecting pole 46, and under the condition that the relay 42 is not electrified, the high-voltage connecting pole 46 is communicated with the structural component 45 through the metal-based switch 44, so that power is supplied to the electrode wire 50 arranged on the structural component 45; when the relay 42 is energized, the metal-based switch 44 is engaged, so that the connection between the high-voltage connection pole 46 and the structural member 45 is broken, thereby interrupting the energization of the wire electrode 50.

It is to be understood that in one embodiment, the relay 42 is connected to the controller 30 specifically as: the relay 42 is connected to a low voltage power source, which is further connected to the controller 30. In the solution of this embodiment, the controller 30 controls the on/off of the low-voltage power supply to control the power-on and power-off of the relay 42.

It should be noted that the type of the supporting member 43 is not exclusive, and in a more detailed embodiment, referring to fig. 7, the supporting member 43 includes a spring 432 and a supporting rod 431, one end of the spring 432 is connected to the base 41, the other end of the spring 432 is connected to the supporting rod 431, and the supporting rod 431 is movably connected to the metal-based switch 44. In the solution of this embodiment, the spring 432 is used as a support, so that even when the movable connection between the metal-based switch 44 and the support 43 fails, the metal-based switch 44 can still be attracted by the relay 42, thereby effectively ensuring the operational reliability of the relay switch.

In one embodiment, the repeller assembly further includes an insulating frame, and the wires 50 are arranged in layers, with the wires 50 being spaced apart by the insulating frame.

Specifically, in the scheme of this embodiment, the wire electrodes 50 are arranged in layers, and the wire electrodes 50 are separated at intervals by the insulating frame, so that mutual interference between the wire electrodes 50 is avoided, and the wire electrodes 50 can be ensured to have better working reliability while the arrangement space of the wire electrodes 50 is effectively saved.

It is understood that it is not unique to how many layers the wire electrode 50 is divided into, for example, in a preferred embodiment, please refer to fig. 8 (only one layer of the wire electrode 50 is shown in the figure), the wire electrode 50 is arranged in three layers, and each layer is provided with five wire electrodes 50. Through this kind of scheme design, total 15 wire electrodes 50 of whole repeller subassembly to satisfy air purifier's purification demand.

In one embodiment, two of the wires 50 in each layer of wires 50 are connected to a power source through the switching device 40.

Specifically, the operation of the air cleaner in which the repeller assembly is located necessarily requires the wire electrode 50 of the repeller assembly to be energized to operate, so as to achieve the dust collecting operation. Therefore, in this embodiment, not all of the wires 50 need to be controlled by the switching device 40 to be connected to the power source, and some of the wires 50 need to be directly connected to the power source, so as to maintain the power-on operation state during the operation of the air purifier. In the solution of this embodiment, the number of the electrode wires 50 that need to be connected to the switching device 40 is specifically six, and for the case that the electrode wires 50 are arranged in three layers, two electrode wires 50 are arranged on each layer and are connected to the power supply through the switching device 40. It will be appreciated that in other embodiments, the number of wires 50 connected to the power supply via the switching device 40 may be different for each layer, or the number of wires 50 connected to the power supply via the switching device 40 may be two, three, four, five, or more than six, etc. in the entire repeller assembly.

Referring to fig. 8, taking three layers of wire electrodes 50, for example, 5 wire electrodes on each layer, the number of each layer of wire electrodes 50 is 1, 2, 3, 4, and 5, specifically, the wire electrodes 50 numbered 2 and 4 may be connected to a power supply through the switching devices 40, and in actual operation, the wire electrodes 50 may be controlled to be connected to the power supply by controlling the on/off of the switching devices 40 corresponding to the wire electrodes 50 numbered 2 and 4.

It will be appreciated that the type of wire electrode 50 employed in the repeller assembly is not exclusive and in one embodiment, a tungsten wire may be employed as the wire electrode 50.

In order to facilitate understanding of the technical solutions of the present application, the present application is explained below with reference to the most specific embodiments. In the embodiment, the switch device adopts a relay switch, and whether the metal-based switch is attracted or not is controlled by switching on or off the relay switch, so that the operation of the corresponding wire electrode is realized, in the scheme of the embodiment, the wire electrodes are divided into 1, 2 and 3, each layer comprises five wire electrodes which are respectively numbered 1, 2, 3, 4 and 5, wherein only the wire electrodes numbered 2 and 4 in each layer are connected with a power supply through the hanging device, and the rest are directly connected with the power supply. Referring to fig. 4, after the controller obtains the concentration value X of the fine particulate matters at the air inlet and the concentration value Y of the fine particulate matters at the air outlet, it is first analyzed whether Y is less than or equal to 10 (a first preset concentration threshold) and whether Y-X is less than 5 (a preset difference threshold), if not, all the electrode wires are connected (the first number), and meanwhile, it is detected whether Y is less than or equal to 10 and whether Y-X is less than 5 again; if yes, whether Y is less than or equal to 5 (a second preset concentration threshold) and whether Y-X is less than 5 are detected. If Y is detected to be less than or equal to 5 and Y-X is detected to be less than 5, the electrode wires numbered 2 and 4 in the layers 1, 2 and 3 are all disconnected, and only 9 electrode wires (the third number) are switched in for operation. And if Y is not less than or equal to 5 and Y-X is less than 5, only switching off the switching devices corresponding to 2 and 4 electrode wires in two layers (1 and 2 layers), switching in 11 (second number) electrode wires for operation, and simultaneously detecting whether Y is less than or equal to 5 and whether Y-X is less than 5. In the whole control process, if a shutdown instruction is received, the power supply is directly disconnected to stop the operation of all the wire electrodes, so that shutdown is realized.

Through this kind of control scheme, can avoid the condition that whole operation in-process wire electrode 50 all inserts the operation to take place, take place the repulsion utmost point when all wire electrodes 50 all insert the operation and strike sparks relatively, and the less wire electrode 50 of quantity takes place under this state of repelling utmost point striking sparks when inserting the operation, and the degree of repelling utmost point striking sparks is lower, and the crackle that sends is also less to experience for the better use of user. Meanwhile, the generation amount of ozone can be reasonably adjusted by matching the access quantity control of the wire electrode 50 with the grade of the cleaning state, so that the stable and energy-saving self-adaptive working state is achieved.
