Description

Technical Field

[0001] The present application relates to but is not limited to the field of air purification technology, and in particular to an electrode module, a dust collecting device and an air treatment device. Background Art

[0002] Dust filtration technology is used to remove various dust particles from the air. Common dust filtration technologies include: mechanical filtration, electrostatic filtration (electrostatic dust collection), wet filtration, molecular adsorption, centrifugal separation, nanotechnology filtration, filter bags, etc. Among them, electrostatic dust collection technology has attracted much attention for its high efficiency, no consumables, and easy maintenance.

[0003] The main electrostatic filtration technologies currently available are:

[0004] 1) Ion precipitation: mainly relies on ions to charge dust and then agglomerate to achieve precipitation;

[0005] 2) ESP (Charging + Metal High-voltage Dust Collection Technology): Relying on wire plates or plasma to charge dust, bacteria and viruses in the air, the high-voltage electric field force formed by the exposed metal dust collecting plate with high voltage electricity adsorbs dust, bacteria and viruses in the air to the surface of the dust collecting plate;

[0006] 3) IFD (charged + insulated conductor dust collection technology): relying on monopolar negative ions, wire plates or plasma to charge dust, bacteria and viruses in the air, and the high-voltage electric field force formed by the dust collecting plate with surface insulation and internal conductivity adsorbs dust, bacteria and viruses in the air to the surface of the dust collecting plate;

[0007] 4) Ion + electret dust collection network technology (i.e. ion + HAF network / HPPA): Rely on the negative ion generator to charge the dust in the air. When the dust in the air passes through the filter with an electret electric field, it is adsorbed to the surface of the filter by the electret electric field.

[0008] The existing electrostatic dust removal technology has the following problems:

[0009] 1) The purification efficiency of ion precipitation technology is low and the purification upper limit is extremely low;

[0010] 2) ESP technology: The metal plate used is easy to arc and ignite, release ozone, and produce unpleasant electric current sound when working;

[0011] 3) Ion + electret dust collection technology: In addition to the ion generator, the electret dust collection net needs to be replaced frequently;

[0012] 4) IFD technology: large wind resistance, complex structure, high processing cost, local electric field loss, inability to achieve overall filtration, and this technology uses conductive graphite as high-voltage conductive material with low conductivity, which will cause high-voltage loss.

[0073] In some exemplary embodiments, the first connection portion 112 and the second connection portion 113 are both sheet-shaped and coplanarly arranged, and the angle between each electrode sheet 111 and the first connection portion 112 is equal to the angle between the electrode sheet 111 and the second connection portion 113 .

[0074] Specifically, Figure 1 As shown, a plurality of electrode sheets 111 are arranged in parallel, and a first connection portion 112 and a second connection portion 113 are arranged in parallel and perpendicular to the electrode sheets 111 (i.e., the angle between the electrode sheet 111 and the first connection portion 112 is 90°, and the angle between the electrode sheet 111 and the second connection portion 113 is 90°). The first connection portion 112 and the second connection portion 113 can be arranged horizontally (or vertically), and the electrode sheet 111 can be arranged vertically (or horizontally).

[0075] In some exemplary embodiments, the insulating layer 12 may include an insulating film attached to the outer surface of the conductive body 11 (such as the electrode sheet 111, the first connecting portion 112 and the second connecting portion 113), wherein the insulating film may be made of any one or more of PP (polypropylene), PET (polyethylene glycol terephthalate), PC (Polycarbonate), and ABS (Acrylonitrile butadiene Styrene copolymers).

[0076] Alternatively, the insulating layer 12 may include an insulating coating applied to the outer surface of the conductive body 11 (e.g., the electrode sheet 111, the first connecting portion 112, and the second connecting portion 113). The insulating coating is made of any one or more of silicone rubber resin coating, polyurethane coating, fluorine-containing polymer coating, polyimide resin coating, and epoxy resin coating.

[0077] The insulating layer 12 may be formed by attaching an insulating film to the outer surface of the conductive body 11 , or by coating the outer surface of the conductive body 11 with an insulating coating formed by an insulating material.

[0078] In some exemplary embodiments, the conductive body 11 is made of conductive metal (eg, copper plate, galvanized plate, stainless steel plate, aluminum plate, etc.) or conductive plastic (eg, conductive plastic with conductive components added).

[0079] The present application also provides a preparation method for preparing the electrode module provided in any of the above embodiments, the preparation method comprising:

[0080] Punching out a first connection portion and a plurality of electrode sheets connected to the first connection portion and separated by gaps on a sheet-shaped conductor, covering the surface of the electrode sheet with an insulating film so that the insulating film wraps the plurality of electrode sheets, punching out the insulating film, and rotating and bending the plurality of electrode sheets to obtain an electrode module;

[0081] Alternatively, a first connecting portion and a plurality of electrode sheets connected to the first connecting portion and cut off from each other are punched out from a sheet-shaped conductor, the plurality of electrode sheets are rotated and bent, and an insulating coating is sprayed on the surfaces of the plurality of electrode sheets to obtain an electrode module;

[0082] Alternatively, the first connecting portion and a plurality of electrode sheets connected to the first connecting portion are obtained by mold injection molding or metal reverse molding, and surfaces of the plurality of electrode sheets are covered with an insulating film or coated with an insulating coating.

[0083] In some exemplary embodiments, the electrode module 1 can be manufactured in the following ways:

[0084] Method 1: The conductor is formed by punching Figure 2 The conductive body 11' (the conductive body 11' is a semi-finished product of the conductive body 11) is provided with a covering insulating film (such as Figure 3 As shown), the insulating film is then punched out by a die, and then the electrode module 1 is formed by rotation and shaping. Figure 1 As shown). The conductor forming the conductive body 11' can be a metal conductor such as a copper plate, a galvanized plate, a stainless steel plate, an aluminum plate, etc. The conductor forming the conductive body 11' can be a whole sheet-shaped conductor, and the insulating film can be a monomer or a composite of plastic films such as PP, PET, PC, ABS, etc., which can withstand high voltage.

[0085] During the processing, a punch press can be used to punch out the conductor so that a gap is formed on the conductor to separate the electrode sheets 111. A laminating machine can be used to adhere the insulating film (the insulating film with adhesive on the back is adhered to the conductive body 11' from the upper and lower sides to at least cover the area where the electrode sheet 111 is located, and the insulating film covers the outer edge of the electrode sheet 111 and the above-mentioned gap). A cutting die can be used to punch out excess insulating film and / or cut off the insulating film between the gaps formed between adjacent electrode sheets 111. The electrode sheet 111 can be rotated by a machine tool so that the electrode sheet 111 of the electrode module 1 can form a certain angle with the first connecting portion 112 and the second connecting portion 113.

[0086] At this time, in the obtained electrode module 1, the width of the electrode sheet 111 (the distance between the side of the electrode sheet 111 connecting the first connecting part 112 and the second connecting part 113 and the side of the electrode sheet 111 away from the first connecting part 112 and the second connecting part 113) is smaller than the distance between two adjacent electrode sheets 111, and the width of the insulating layer 12 covering the electrode sheet 111 (the size of the insulating layer 12 in the width direction of the electrode sheet 111) is smaller than or equal to the distance between two adjacent electrode sheets 111.

[0087] The electrode module 1 formed in this way has a simpler processing procedure than the prior art, and the insulating layer 12 formed by the insulating film has a uniform thickness and good high-voltage resistance.

[0088] Method 2: The conductor is directly punched (cutting off adjacent electrode sheets 111) and rotated to form a conductive body 11, and an insulating coating is applied to the outer surface of the conductive body 11. The conductor can be a metal conductor such as a copper plate, a galvanized plate, a stainless steel plate, an aluminum plate, etc., and the insulating component of the insulating coating can be a silicone rubber resin coating, a polyurethane coating, a fluorine-containing polymer coating, a polyimide resin coating, an epoxy resin coating, or a mixture of these materials, preferably an epoxy resin and a fluorine-containing polymer coating.

[0089] At this time, in the obtained electrode module 1 , the width of the electrode sheet 111 may be less than or equal to the distance between two adjacent electrode sheets 111 .

[0090] Method 3: After mold injection molding or metal reverse molding (directly molded into a shape where the electrode sheet 111 is bent relative to the first connection part 112 and the second connection part 113 on both sides without an additional bending process), the conductive body 11 is formed, and an insulating film or an insulating coating is applied to the outer surface of the conductive body 11. Among them, the conductor can be a metal conductor such as a copper plate, a galvanized plate, a stainless steel plate, an aluminum plate, or a conductive plastic with a conductive component added, the insulating film can be a monomer or a composite of plastic films such as PP, PET, PC, ABS, etc., and the insulating coating can be a silicone rubber resin coating, a polyurethane coating, a fluorine-containing polymer coating, a polyimide resin coating, an epoxy resin coating, or a mixture of these materials, preferably epoxy resin and fluorine-containing polymer coating.

[0091] At this time, in the obtained electrode module 1 , the width of the electrode sheet 111 may be smaller than, equal to, or larger than the distance between two adjacent electrode sheets 111 .

[0092] In some exemplary embodiments, the thickness of the insulating layer 12 is 10 μm to 700 μm, such as 50 μm, 100 μm, 200 μm, 300 μm, 400 μm, 500 μm, 600 μm, 700 μm. Preferably, the thickness of the insulating layer 12 can be set to 100 μm to 200 μm.

[0093] The thickness of the insulating layer 12 is set to 10μm to 700μm. While ensuring that the electrode module 1 will not be ionized with the air, no ozone will be generated, and no arcing will occur after being powered on, it is convenient to form the insulating layer 12 by bonding an insulating film to the outer surface of the conductive body 11, or by coating an insulating coating on the outer surface of the conductive body 11 to form the insulating layer 12.

[0094] Of course, the thickness of the insulating layer 12 is not limited to the above range and can be adjusted according to actual needs.

[0095] In some exemplary embodiments, Figure 1 As shown, the end of the first connection portion 112 not covered with the insulating layer 12 forms a terminal 116 .

[0096] One end of the first connection portion 112 may not be covered with the insulating layer 12 , and the end not covered with the insulating layer 12 may form a connection terminal 116 , which may be electrically connected to a power source so that the electrode module 1 is powered on.

[0097] In summary, the electrode module 1 of the embodiment of the present application has the following beneficial effects:

[0098] 1. The conductive body 11 is an integrated structure with high conductivity, which can avoid voltage loss. Therefore, after power is turned on, the overall potential of the electrode module 1 is high and uniform, and the air filtering and dust collection efficiency is high;

[0099] 2. After the conductive body 11 is energized, a high-voltage array ring can be formed, covering the entire module, thereby avoiding local high-voltage field defects;

[0100] 3. Through the processing method of once punching and forming the conductor, once laminating and cutting, and rotating and finalizing, the electrode module 1 formed has a simple structure, and can realize the automatic production of the module with lower cost;

[0101] 4. The outer surface of the conductive body 11 is substantially completely covered by the insulating film, so that the electrode module 1 will not be ionized with the air, no ozone will be generated, and no arcing will occur.

[0102] The present application also provides a dust collecting device 100, such as Figure 4-Figure 7 As shown, it includes the electrode module 1 provided by any of the above embodiments.

[0103] In some exemplary embodiments, Figure 4-Figure 7 As shown, the electrode module 1 is provided with a plurality of electrode sheets 111 of the conductive bodies 11 of the plurality of electrode modules 1 are plugged in and arranged alternately in sequence, and a ventilation gap 6 is provided between two adjacent electrode sheets 111 .

[0104] The electrode sheets 111 of the multiple electrode modules 1 are interlaced with each other to form a high-low voltage interlaced structure or a high-voltage and 0-pole interlaced structure, wherein a ventilation gap 6 is formed between two adjacent electrode sheets 111. When the airflow passes through the ventilation gap 6, the charged particles in the air can move under the action of the electric field between the two adjacent electrode sheets 111 and be adsorbed onto the electrode sheets 111 to achieve a dust removal effect.

[0105] In some exemplary embodiments, Figure 7 As shown, the gap d between two adjacent electrode sheets 111 is greater than or equal to 0.5 mm.

[0106] The gap d between two adjacent electrode sheets 111 is ≥ 0.5 mm, and there is a voltage difference between two adjacent electrode sheets 111 . The voltage difference may range from 0 kV to 100 kV, and more preferably, the voltage difference may range from 1.5 kV to 50 kV.

[0107] In some exemplary embodiments, the plurality of electrode modules include at least one first electrode module and at least one second electrode module, the electrode sheets of the first electrode module and the electrode sheets of the second electrode module are arranged alternately in sequence, and the first electrode module and the second electrode module are respectively connected to different power output terminals, so that a voltage difference is formed between the electrode sheets of the first electrode module and the electrode sheets of the second electrode module. The first connection portion of the first electrode module and the first connection portion of the second electrode module are separated from each other to reduce the risk of creepage or electrical breakdown.

[0108] The first connection portion of the first electrode module and the first connection portion of the second electrode module may be spaced apart in the ventilation direction of the ventilation gap. For example, the first connection portion of the first electrode module may be located upstream of the ventilation gap, and the first connection portion of the second electrode module may be located downstream of the ventilation gap.

[0109] Alternatively, the first connection portion of the first electrode module and the first connection portion of the second electrode module can be spaced apart in a direction perpendicular to the ventilation direction of the ventilation gap, for example, the first connection portion of the first electrode module can be located on the left side of the ventilation gap, and the first connection portion of the second electrode module can be located on the right side of the ventilation gap.

[0110] The number of first electrode modules can be multiple, and the first connection parts of multiple first electrode modules are connected, and the first connection parts of multiple first electrode modules are conductively connected, so that it is convenient to supply power to multiple first electrode modules at the same time through the terminal of the first connection part of one first electrode module, for example, the parts of the first connection parts of multiple first electrode modules that are not covered by the insulating layer are attached to each other. The electrode sheets of multiple first electrode modules are plugged in at intervals and parallel to each other, which can reduce the distance between the electrode sheets of the same pole in the dust collecting device 100. Similarly, the number of second electrode modules can also be multiple, and the first connection parts of multiple second electrode modules are connected, and the electrode sheets of multiple second electrode modules are plugged in at intervals and parallel to each other.

[0111] The number of the first electrode modules can be equal to the number of the second electrode modules, the electrode sheets of the first electrode modules and the electrode sheets of the second electrode modules have the same size, and the electrode sheets of the first electrode modules face the electrode sheets of the second electrode modules to form a uniform electric field.

[0112] The first electrode module and the second electrode module may have the same shape and structure, and the two are arranged symmetrically with respect to the center and the electrode sheets of the two are plugged into each other. The first electrode module and the second electrode module may be manufactured by the same mold, thereby saving costs.

[0113] In some exemplary embodiments, Figure 4-Figure 5As shown, the dust collecting device 100 also includes an insulating frame 2 and a fixing card 3, the electrode sheets 111 of the multiple electrode modules 1 are interlaced and inserted with each other, the multiple electrode modules 1 can be fixed to the insulating frame 2 through the fixing card 3, and the connection terminals 116 of the multiple electrode modules 1 can be electrically connected to the spring sheet 5, the spring sheet 5 can be electrically connected to the power supply module through a high-voltage line, and the circuit formed by the multiple electrode modules 1 and the power supply module can be provided with a high-voltage resistor.

[0114] In the embodiment of the present application, the conductor can be cut and then covered with an insulating film, and then the electrode module 1 can be formed by cutting the film and rotating it, and two or more electrode modules 1 can be assembled into an insulating frame 2 to form a dust collecting device 100, which can utilize static electricity. In the embodiment of the present application, the processing process of the dust collecting device 100 is simplified, and the conductivity coefficient of the conductive body 11 is higher, ensuring that the overall electric field of the dust collecting device 100 is higher and more uniform, and the filtering efficiency is higher.

[0115] An embodiment of the present application also provides an air treatment device, comprising a dust collection device 100, a power supply module and a control device provided in any of the above embodiments, wherein the power supply module is configured to supply power to the dust collection device 100, and the control device is configured to control the amount of power supplied by the power supply module to the dust collection device 100.

[0116] Specifically, when performing dust removal, the control device can control the power supply module to supply power to the dust collecting device 100 so that the dust collecting device 100 performs electrostatic dust collection. In addition, the control device can also control the voltage or current of the power supply module to supply power to the dust collecting device 100 to control the dust collection efficiency and dust collection effect.

[0117] In some exemplary embodiments, the air treatment equipment also includes a dust collection sensor (dirty blockage sensor), which is configured to detect the dust collection condition of the dust collection device 100. The control device is configured to receive the detection signal of the dust collection sensor, and control whether the power supply module supplies power to the dust collection device 100 according to the detection signal of the dust collection sensor, and / or send a reminder signal to clean the dust collection device 100.

[0118] The dust collection sensor (dirty and blocked sensor) can detect the dust collection condition of the dust collecting device 100 (i.e., the dust collecting module on the electrode sheet 111 of the electrode module 1 of the dust collecting device 100, i.e., the dirty and blocked condition of the dust collecting device 100). When the dust collection condition of the dust collecting device 100 reaches the dust collection threshold, the control device can send a reminder signal to remind the user to clean the dust collecting device 100 in time, and control the power supply module to stop supplying power to the dust collecting device 100; when the dust collection condition of the dust collecting device 100 does not reach the dust collection threshold, the control device can control the power supply module to supply power to the dust collecting device 100 for dust removal.

[0119] In some exemplary embodiments, the air handling device further comprises a fan device, which is configured to form an airflow passing through the dust collecting device 100 to achieve dust collection.

[0120] The dust collecting sensor is configured to detect the parameters of the airflow passing through the dust collecting device 100, and the parameters of the airflow include wind speed and / or wind pressure. The dust collecting sensor for detecting wind speed may be disposed on one side of the dust collecting device 100 (e.g., the downstream side of the dust collecting device 100), or may be disposed on both sides of the dust collecting device 100 (e.g., the upstream and downstream sides of the dust collecting device 100); or, the dust collecting sensor for detecting wind pressure may be disposed on one side of the dust collecting device 100 (e.g., the upstream side of the dust collecting device 100), or may be disposed on both sides of the dust collecting device 100 (e.g., the upstream and downstream sides of the dust collecting device 100). The dust collecting device 100 may be a pressure-sensitive sensor or other types of sensors.

[0121] Dust is collected on the dust collecting device 100, which will affect the wind speed or wind pressure upstream and downstream of the dust collecting device 100 (such as: reducing the wind speed on the downstream side of the dust collecting device 100 and increasing the wind pressure on the upstream side of the dust collecting device 100). Therefore, the dust collection situation on the dust collecting device 100 can be known by detecting the wind speed or wind pressure upstream and downstream of the dust collecting device 100.

[0122] Alternatively, the dust collecting sensor is configured to detect the power of the motor of the fan device. Dust collection on the dust collecting device 100 will increase the wind pressure and the power of the motor of the fan device. Therefore, the dust collection condition on the dust collecting device 100 can be known by detecting the power of the motor.

[0123] Alternatively, the dust collection sensor includes a light emitting component and a light receiving component, the light emitting component and the light receiving component are respectively arranged at the upstream and downstream of the dust collection device 100, and the light receiving component is arranged to receive the light emitted by the light emitting component and projected through the dust collection device 100. When the light emitting component and the light receiving component are used for detection, the circuit structure adopted is as follows: Figure 8 The light emitting component may include a light emitting tube, such as a light emitting diode LED, the light receiving component may include a light receiving tube PD, and the circuit structure may include a light emitting diode switch control circuit A1, a power supply circuit A2 and an external detection circuit A3.

[0124] The dust collection sensor utilizes the obstruction of dust to the propagation of light. A light emitting component is installed on one side (e.g., the upstream side) of the dust collecting device 100, and a light receiving component is installed on the other side (e.g., the downstream side). The dust collection condition of the dust collecting device 100 is judged based on the intensity of the light received by the light receiving component.

[0125] Of course, the dust collection sensor can also detect the dust collection condition of the dust collection device 100 in other ways.

[0126] In some exemplary embodiments, the air treatment device also includes an air quality sensor, which is configured to detect indoor air quality. The control device is configured to receive a detection signal from the air quality sensor and control the power supply module to supply power to the dust collection device 100 based on the detection signal from the air quality sensor.

[0127] The air quality sensor can be installed at the air inlet or other location of the air handling equipment and can be used to detect the indoor air quality. For example, the air quality sensor can be a dust sensor that can detect the concentration of particulate matter PM2.5 in the indoor air. The control device can control the voltage or current of the power supply module to the dust collection device 100 according to the indoor air quality to control the dust collection efficiency and dust collection effect.

[0128] In some exemplary embodiments, the air treatment device further includes a charging module, and the charging module may be located upstream of the dust collecting device 100 along the flow direction of the airflow.

[0129] When air passes through the charging module, the charging module can charge the particles in the air so that the charged particles can be subsequently adsorbed by the dust collecting device 100 to achieve dust removal.

[0130] In some exemplary embodiments, the air treatment device may be an air conditioner. Of course, the air treatment device is not limited to an air conditioner, and may also be an air purifier or other types of equipment with air purification functions.

[0131] The present application also provides a control method for controlling the air treatment device provided in any of the above embodiments. Fig. 9 As shown, the control method includes:

[0132] S102: Based on the activation of the dust removal function, the power supply module is controlled to provide a power supply voltage Vd for the dust collecting device according to the expected purification efficiency e and the indoor air quality.

[0133] After the dust removal function of the air conditioner is started, the power supply module is controlled to supply the power voltage Vd to the dust collecting device 100 according to the expected purification efficiency e and the indoor air quality detected by the air quality sensor, thereby controlling the dust removal efficiency of the dust collecting device 100 to meet the dust removal needs.

[0134] In some exemplary embodiments, the supply voltage Vd satisfies: Vd=d×e×k×10 kV.

[0135] Wherein, d represents the distance between two adjacent electrode sheets of the dust collecting device (in mm), e represents the expected purification efficiency (in %), k represents the voltage coefficient (in 1 / mm), and the value of k is related to the indoor air quality. The worse the indoor air quality, the larger the value of k. In some exemplary embodiments, the value range of k is 0.2-0.8, such as: 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, etc. Of course, the value range of k is not limited to 0.2-0.8, and can also be adjusted according to actual needs.

[0136] The voltage coefficient k can be determined according to the indoor air quality level detected by the air quality sensor, as shown in Table 1. Of course, it is not limited to determining the air quality level according to the concentration of PM2.5, and then determining the voltage coefficient k. The voltage coefficient k can also be determined according to the concentration of other pollutants in the air (such as VOCs, etc.).

[0137] Table 1

[0138]

[0139]

[0140] The power supply voltage Vd is positively correlated with d, e, and k. The larger the values ​​of d, e, and k, the larger the power supply voltage Vd. The larger d is, the larger the distance between two adjacent electrode sheets 111 is. Therefore, the larger the power supply voltage Vd required by the dust collecting device 100 is, the greater the electric field strength between two adjacent electrode sheets 111 can be ensured to meet the requirements; the larger e is, the higher the requirements for dust removal efficiency and dust removal effect are. Therefore, the larger the power supply voltage Vd required by the dust collecting device 100 is, the greater the dust removal efficiency and dust removal effect can be ensured; the larger k is, the worse the indoor air quality is. Therefore, the larger the power supply voltage Vd required by the dust collecting device 100 is, the greater the dust removal effect can be ensured.

[0141] In some exemplary embodiments, the expected purification efficiency e may be related to the cleaning frequency of the dust collecting device 100, and the expected purification efficiency e is positively correlated with the cleaning frequency of the dust collecting device 100. The expected purification efficiency e or the cleaning frequency of the dust collecting device 100 may be a default or preset by the user. The value range of the expected purification efficiency e may be 60%-100%, for example: 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, etc.

[0142] The higher the cleaning frequency of the dust collecting device 100, the shorter the time taken by the dust collecting device 100 for one cleaning, indicating that the air quality is worse. Therefore, the expected purification efficiency e is set higher to increase the power supply voltage Vd required by the dust collecting device 100 to meet the dust removal needs.

[0143] Of course, the value range of the desired purification efficiency e is not limited to 60%-100%, and can be adjusted as needed.

[0144] In some exemplary embodiments, the supply voltage Vd has a value range of greater than 0 kV and less than or equal to 100 kV.

[0145] For example: In one embodiment, the spacing d between two adjacent electrode sheets 111 is 1.5 mm, the expected purification efficiency e is 90%, and the voltage coefficient k is 0.6. Then, the power supply voltage of the dust collecting device 100 (the voltage difference between adjacent electrode sheets 111) Vd=1.5×90%×0.6×10=8.1 kV.

[0146] In some exemplary embodiments, the control method further includes:

[0147] Check the dust collection condition of the dust collection device;

[0148] When the dust collection condition of the dust collection device reaches a dust collection threshold, the user is reminded to clean the dust collection device;

[0149] Based on the fact that the dust collection condition of the dust collection device does not reach the dust collection threshold, the dust removal function is started.

[0150] The dust collection sensor can be used to detect the dust collection condition of the dust collection device 100. When the dust collection condition of the dust collection device 100 reaches the dust collection threshold, the control device can send a reminder signal to remind the user to clean the dust collection device 100 in time, and control the power supply module to stop supplying power to the dust collection device 100, and no dust removal is performed at this time; when the dust collection condition of the dust collection device 100 does not reach the dust collection threshold, the control device can control the power supply module to supply power to the dust collection device 100 to perform dust removal.

[0151] The dust collection threshold (dirty blockage threshold) P0 can be set according to the characteristics of the dust collection sensor. In the case where the dust collection sensor includes a light emitting component and a light receiving component respectively arranged upstream and downstream of the dust collection device 100, it can be determined whether the dust collection condition of the dust collection device 100 reaches the dust collection threshold according to the size relationship between the real-time dust collection value (real-time dirty blockage value) Pt detected by the dust collection sensor and the preset dust collection threshold (dirty blockage threshold) P0. Among them, the light receiving component is affected by the dirtiness and blockage of the dust collection device 100, and the voltage changes. Therefore, the preset dust collection threshold (voltage threshold) P0 can be set to 3V.

[0152] When the real-time dust collection value (real-time dirty and clogging value) Pt detected by the dust collection sensor is less than the dust collection threshold (dirty and clogging threshold) P0, the display panel or APP of the air treatment equipment can remind the user that maintenance of the dust collection device 100 is required; when Pt≧P0, the input voltage of the dust collection device 100 can be controlled to work.

[0153] In some exemplary embodiments, air handling equipment, such as an air conditioner, can control an air quality sensor (such as a dust sensor) through a control device to detect indoor air quality (such as detecting dust concentration data in indoor air), and control a power supply module to input high voltage to the dust collecting device 100. At the same time, the dust collecting sensor can feedback the dirtiness and blockage of the dust collecting device 100 to remind the user to clean and maintain the dust collecting device 100. The specific control process is as follows: Fig.10 As shown, the air conditioner is turned on, and the user selects automatic dust removal or presets the expected purification efficiency e (the expected purification efficiency e can be set according to the cleaning frequency of the dust collecting device by the user), and the dust collecting sensor detects the dirtiness and blockage of the dust collecting device. When the real-time dust collection value (real-time dirtiness and blockage value) Pt<dust collection threshold (dirtyness and blockage threshold) P0, the display panel or APP of the air conditioner can remind the user that the dust collecting device needs to be maintained; when Pt≧P0, the dust sensor is controlled to collect the indoor air quality, and the power supply voltage Vd of the dust collecting device is obtained through a preset calculation formula to control the dust collecting device to work.
