FIELD

[0001] The present application relates to the field of air purification, and particularly, relates to air purification equipment.BACKGROUND

[0002] An air purifier can adsorb pollutants in the air through an electric field generated when powered on to achieve the purpose of air purification.

[0003] In related technologies, an air purifier often collects pollutants in the air through a built-in air duct and an air chamber; however, this solution requires introducing air into the air duct and the air chamber first, and this affects the purification efficiency; moreover, it is difficult to clean dust in the future for the built-in air duct and the air chamber, and user experience can be easily ruined.SUMMARY

[0004] The present application aims to solve at least one of the problems existing in the prior art or related art.

[0005] Therefore, the present application provides air purification equipment.

[0006] In view of this, the present application provides air purification equipment, and the air purification equipment comprises: a main body; a dust collection assembly, provided in the main body, and the dust collection assembly comprises a dust collection surface, the dust collection assembly can generate an electric field when powered on, the dust collection surface is at least partially exposed, and the at least partially exposed dust collection surface is configured to collect pollutants in the air outside the main body through the electric field.

[0007] The present application defines the air purification equipment, and the air purification equipment is configured to treat pollutants in the air, to achieve the effect of reducing the content of pollutants in the air. And the air purification equipment comprises the dust collection assembly.

[0008] The dust collection assembly comprises the dust collection surface; when the dust collection assembly is powered on, electric ions are accumulated therein, and under the action of the accumulated electric ions, an electric field can be generated; the electric field forms an electric field area at the front side of the dust collection surface, and the pollutants in the electric field area will be polarized; the polarized pollutants move towards the dust collection surface under the action of Coulomb force until the pollutants are adsorbed on the dust collection surface. Under the adsorption effect, the concentration of the pollutants in the electric field area decreases; and under the effect of concentration difference, the pollutants outside the electric field area migrate to the electric field area with a low concentration, and thus, the concentration of the pollutants in the entire environment is reduced and the air purification effect is achieved.

[0009] At least a portion of the dust collection surface on the dust collection assembly is an exposed surface exposed to the outer side of the air purification equipment, and the exposed dust collection surface can form an electric field area at the outer side of the air purification equipment, and thereby directly collects the pollutants outside the air purification equipment through the electric field area.

[0010] Thus, through disposing the exposed dust collection surface and the cooperation with the exposed dust collection surface, the present application enables the air purification equipment to directly collect the pollutants in the outside air, and thus, avoids a structure for introducing air into the interior of the air purification equipment in related technologies and eliminates an internal purification solution. Compared with the internal purification solution, without the limitation of an internal structure, the area of the exposed dust collection surface can be enlarged more easily, to improve the purification capacity and the purification efficiency of the air purification equipment through a large-area dust collection surface; moreover, the front side of the exposed dust collection surface is not easily blocked, and this is conducive to expanding the coverage area of the electric field area, to further improve the purification capacity and the purification efficiency of the air purification equipment, and thus solve the problems of insufficient purification capacity and low purification efficiency in related technologies. At the same time, the difficulty of cleaning the exposed dust collection surface is relatively low, and a user can directly wipe off the pollutants on the exposed dust collection surface to avoid excessive pollutants adhering to the dust collection surface, and thus, the problems of difficult cleaning and poor user experience in related technologies are solved.

[0011] On the above basis, the dust collection assembly provided in the present application collects the pollutants through the electric field, and the collected pollutants adhere to the dust collection surface; after use, the pollutants can be removed by cleaning or wiping the dust collection surface, and thus the operation of frequently replacing filter materials is avoided to reduce the use cost of the air purification equipment. Meanwhile, the noise generated by the dust collection assembly when powered on is relatively small, and this can further improve the user experience.

[0012] In an embodiment, the dust collection assembly provided in the present application can actively adsorb the pollutants in the air through the electric field generated by the dust collection assembly itself, the present application does not need a circulating airflow to achieve an air purification function and thus saves the space for arranging an air duct and a fan, and this provides a convenient condition for the miniaturization design and the lightweight design of the air purification equipment.

[0013] The pollutants mentioned in the present application are mainly solid particulate pollutants, and the solid particulate pollutants in the air comprise dust, smoke, particles, bacteria, viruses, etc. Their diameters are not exactly the same, and they can generally be classified into the following categories based on the diameter sizes:

[0014] Visible particles: particles having a diameter less than or equal to 10 microns, the presence of the particles can be seen, such as dust, pollen, and human dander.

[0015] Fine particles: particles having a diameter less than or equal to 2.5 microns, the particles cannot be seen by naked eyes, but have a significant influence on human health, such as car exhaust and factory exhaust.

[0016] Ultra fine particles: particles having a diameter less than or equal to 0.1 micron, the particles cannot be seen by naked eyes, but can penetrate deep into the human respiratory tract and have a greater influence on human health, such as viruses and bacteria.

[0017] In addition, the air purification equipment in the above embodiment provided by the present application can further have the following additional features: In some embodiments of the present application, the main body comprises: a discharging component, and the discharging component is configured to discharge electricity to the area which the at least partially exposed dust collection surface faces; and the dust collection assembly is configured to connect one of a positive electrode and a negative electrode, and the discharging component is configured to connect the other one of the positive electrode and the negative electrode.

[0018] In the embodiment, the air purification equipment further comprises the discharging component; the discharging end of the discharging component faces the electric field area outside the air purification equipment, and the discharging component can release electric ions into the electric field area, and the released electric ions can act on the pollutants in the electric field area. The air purification equipment further comprises a power supply component; one of the positive electrode and the negative electrode of the power supply component is connected to the dust collection assembly, and the other one is connected to the discharging component, and the polarity of the electric ions accumulated inside the dust collection assembly is opposite to the polarity of the electric ions released by the discharging component.

[0019] The electric ions released by the discharging component will adhere to the pollutants in the electric field area, and the pollutants carry opposite electricity to the dust collection assembly, and thus the adsorption force of the dust collection assembly on the pollutants is increased on the basis of the original Coulomb force, then the pollutants are made to accelerate movement towards the dust collection surface, thereby the adsorption capacity of the dust collection assembly is enhanced, and this compensates for the shortcomings of electric field adsorption, and improves the purification capacity of the air purification equipment.

[0020] In an embodiment, the dust collection assembly and the discharging component can be a split structure, the dust collection assembly and the discharging component are powered independently, and the positions of the dust collection assembly and the discharging component can be freely adjusted based on scene needs. During the use, the arrangement of the dust collection assembly is first accomplished, and then the discharging component is placed in the electric field area generated by the dust collection assembly, to ensure that the discharging component can effectively cooperate with the dust collection assembly to adsorb the pollutants in the air.

[0021] In an embodiment, the dust collection assembly and the discharging component can be an integrated structure, for example, the dust collection assembly is directly connected to the discharging component, or the dust collection assembly and the discharging component are fixed on the same base. Under the integrated structure, the relative positions of the dust collection assembly and the discharging component are locked, and this can ensure that the discharging component can discharge electricity to the electric field area generated by the dust collection assembly.

[0022] In some embodiments of the present application, the discharging component comprises a connecting end and a transmitting end; the connecting end is connected to a support, and the transmitting end is for discharging electricity.

[0026] In the embodiment, the dust collection assembly and the discharging component can be supplied with power independently to help achieve the split design of the dust collection assembly and the discharging component. The dust collection assembly is connected to the power supply through the first voltage regulator; under the voltage regulation of the first voltage regulator, the potential of the dust collection assembly is higher than the ground potential, and a positive voltage is formed between the dust collection assembly and a zero-pole. Correspondingly, the discharging component is connected to the power supply through the second voltage regulator; under the voltage regulation of the second voltage regulator, the potential of the discharging component is lower than the ground potential, and a negative voltage is formed between the discharging component and the zero-pole; the discharging component carrying the negative voltage can release negative ions into the air, this causes the pollutants in the air to be negatively charged; after being negatively charged, the pollutants will move towards the dust collection assembly that is positively charged and are finally captured by the dust collection assembly, and thus the pollutants in the air are removed. In some embodiments of the present application, the air purification equipment further comprises a base, and the dust collection assembly and the discharging component are arranged on the base.

[0029] Meanwhile, the base has a relatively large contact surface and a relatively low center of gravity, and can reduce the tilting or collapsing probability of the dust collection assembly and the discharging component.

[0030] On the above basis, the dust collection assembly is plate-shaped, and the plate-shaped dust collection assembly is mounted above the base; after the dust collection assembly is assembled, at least a portion of the dust collection surface on the dust collection assembly is exposed outside the base, to form an electric field area above the base, and thereby, the pollutants in the air near the base are collected through the electric field area.

[0031] Disposing the dust collection assembly in a plate shape helps increase the total area of the exposed dust collection surface, and thus, the purification capacity and the purification efficiency of the air purification equipment are improved by increasing the exposed area of the dust collection surface.

[0032] In an embodiment, the shapes of the cross section of the plate-shaped dust collection assembly comprise a rectangular shape, a curved shape and a circular shape.

Thus, the slot can play a role of positioning the dust collection assembly, to ensure that the dust collection assembly can be fixed at a predetermined working position.

[0035] Meanwhile, the dust collection assembly can be disassembled and assembled through simple plugging and unplugging actions, and this helps reduce the difficulty of cleaning the dust collection assembly; in an embodiment, a user can unplug the dust collection assembly from the slot and re-insert it back into the slot after the wiping is accomplished.

[0036] On the above basis, after the plug-in assembly of the dust collection assembly is accomplished, the dust collection assembly is partially inserted into the slot, and partially located outside the slot, and the dust collection surface on the dust collection assembly is at least partially exposed outside the slot, and thereby, the adsorption efficiency and the adsorption capacity of the dust collection assembly for the pollutants are improved.

[0037] In some embodiments of the present application, the dust collection assembly is connected to the base, and the entire dust collection assembly is located outside the base.

[0038] In the embodiment, the dust collection assembly is fixed above the base; after the dust collection assembly is assembled, the entire dust collection assembly is located outside the base, and the dust collection surface on the dust collection assembly is completely exposed outside the base, to prevent the base from blocking the dust collection surface; therefore, the purification efficiency and the purification capacity of the air purification equipment are improved by increasing the exposed area of the dust collection surface.

[0039] In an embodiment, the dust collection assembly can be fixed to the outer side of the base through a connecting member such as a screw, and can further be buckled to the outer side of the base through a buckle.

[0040] In some embodiments of the present application, the main body further comprises a frame, and the dust collection assembly is provided within the frame, the frame comprises a window, and the dust collection surface is exposed through the window.

[0041] In the embodiment, the air purification equipment further comprises the frame, the frame is connected to the base, an accommodating chamber is formed inside the frame, and a window communicating the accommodating chamber with the external space of the frame is further opened in the frame. And the dust collection assembly is mounted in the accommodating chamber, and the frame can play a role of positioning, protecting and supporting the dust collection assembly, to lower the possibility of damaging the dust collection assembly due to external impact.

[0042] On the above basis, the dust collection surface on the dust collection assembly is exposed through the window; during a working process, the dust collection assembly forms an electric field area at the front side of the window; the pollutants in the electric field area move towards the dust collection surface at the inner side of the window under the action of Coulomb force and are finally captured by the dust collection surface; firstly, the window can reduce the probability of scraping and impacting the dust collection surface, and secondly, the window can play a role of gathering the pollutants adsorbed on the dust collection surface and blocking the airflow blowing towards the dust collection surface, to reduce the possibility of a secondary pollution caused by the pollutants on the dust collection surface.

[0043] During a cleaning process, a user can directly wipe the pollutants on the dust collection surface at the inner side of the window, and can further disassemble the frame to perform a deep cleaning on the dust collection surface.

[0044] In some embodiments of the present application, the air purification equipment further comprises a power supply component provided on the base, and the power supply component comprises a positive electrode and a negative electrode; the positive electrode is connected to one of the dust collection assembly and the discharging component, and the negative electrode is connected to the other one of the dust collection assembly and the discharging component.

[0045] In the embodiment, the air purification equipment further comprises the power supply component; one of the positive electrode and the negative electrode on the power supply component is connected to the dust collection assembly, and the other one is connected to the discharging component, and the polarity of the electric ions accumulated inside the dust collection assembly is opposite to the polarity of the electric ions released by the discharging component. The electric ions released by the discharging component will adhere to the pollutants in the electric field area, and the pollutants carry opposite electricity to the dust collection assembly, and thus, the adsorption force of the dust collection assembly on the pollutants is increased on the basis of the original Coulomb force, the pollutants are made to accelerate movement towards the dust collection surface, thereby the adsorption capacity of the dust collection assembly is enhanced, and this compensates for the shortcomings of electric field adsorption, and solves the problems in related technologies that the Coulomb force on the pollutants does not meet a standard, the pollutant capturing ability is insufficient, and the purification effect is poor.

[0048] In the embodiment, there are multiple discharging needles provided on the support, and the multiple discharging needles are arranged side by side on the support. By arranging multiple discharging needles side by side on the support, the coverage range of the electric ions released by the discharging needles can be expanded, and thereby the overlap degree between the coverage area of the electric ions and the electric field area is improved, to increase the number of the electric ions released into the electric field area and lower the difficulty that the pollutants adhere to the electric ions in the electric field area, and then the effect of improving the adsorption capacity of the dust collection assembly for the pollutants is achieved.

[0049] In some embodiments of the present application, the dust collection assembly comprises: protective plates, and the number of the protective plates is N, N is an integer greater than 1, the N protective plates are stacked, and two adjacent protective plates are spaced apart from each other; a conductive component, provided between two adjacent protective plates, and the conductive component is configured to generate the electric field when powered on; and the surface of the protective plate facing away from the conductive component is the dust collection surface.

The conductive component is provided in the gap between the two adjacent protective plates, and can generate an electric field after being powered on. On the multiple protective plates, the surface facing away from the conductive component is the dust collection surface, for example, when the number of the protective plates is two, the outer side surfaces of the two protective plates form two dust collection surfaces; when the number of the protective plates is three, the two surfaces on the middle protective plate both face the conductive component and do not form the dust collection surface; the outer side surfaces of the protective plates located at two sides form two dust collection surfaces, i.e., increasing the number of the protective plates will not increase the number of the dust collection surfaces.

[0051] In an embodiment, the air purification equipment further comprises the power supply component, and the power supply component is provided in the base; the power supply component comprises a positive electrode and a negative electrode, and the conductive component is connected to the positive electrode to supply a positive DC high voltage to the conductive component through the power supply component. After the positive DC high voltage is supplied to the conductive component, a large number of negative ions can be stored in the conductive component, and thus an electric field is formed. After moving into the electric field area, the pollutants are polarized under the action of the electric field and are adsorbed onto the dust collection surface, during the process of approaching the dust collection surface, the closer the distance to the dust collection surface is, the stronger the adsorption force is; therefore, the pollutants undergo a process of accelerating movement towards the dust collection surface.

[0052] On the above basis, the surface of the protective plate facing the conductive component is covered with a first conductive layer, and the electric field can be enhanced by providing the first conductive layer, to strengthen the adsorption capacity of the dust collection assembly for the pollutants. In an embodiment, the first conductive layer is a barium carbonate coating.

[0053] In an embodiment, the protective plate is a silicon dioxide tempered glass plate, and the silicon dioxide tempered glass plate has the advantages of high strength, strong corrosion resistance and insulation, and can provide a long-term and effective protection for the inside conductive component, and thus, the reliability of the dust collection assembly is improved and the failure rate of the dust collection assembly is reduced. At the same time, the insulation property can avoid the problem of electricity leakage of the dust collection assembly, and thus improving the safety of the dust collection assembly.

[0054] In an embodiment, the conductive component comprises a conductive wire and a second conductive layer; the conductive wire is electrically connected to the power supply component, and the second conductive layer is wrapped around the conductive wire. By setting the second conductive layer, the conductivity of the conductive component can be further improved, and thus, the strength of the electric field is further improved, to enhance the adsorption capacity of the dust collection assembly for the pollutants.

[0055] In an embodiment, the conductive wire is an aluminum wire, and the second conductive layer is a graphene coating.

[0056] In an embodiment, a conductive foam is further provided between two adjacent protective plates, and the conductive foam cooperates with the conductive wire and the second conductive layer to fill the gap between the two adjacent protective plates.

Therefore, the protection scope of the present application is not limited to the specific embodiments disclosed in the following text.

[0062] Air purification equipment according to some embodiments of the present application is described in the following by referring to FIG. 1 to FIG. 9.

[0063] As shown in FIG. 1, FIG. 2 and FIG. 4, an embodiment of the present application provides air purification equipment 100, and the air purification equipment 100 comprises: a main body 1002; a dust collection assembly 120, provided in the main body 1002, and the dust collection assembly 120 comprises a dust collection surface 122, the dust collection assembly 120 can generate an electric field when powered on, the dust collection surface 122 is at least partially exposed, and the at least partially exposed dust collection surface 122 is configured to collect pollutants 200 in the air outside the main body 1002 through the electric field.

And the air purification equipment 100 comprises the dust collection assembly 120.

[0067] The dust collection assembly 120 comprises the dust collection surface 122; when the dust collection assembly 120 is powered on, electric ions are accumulated therein, and under the action of the accumulated electric ions, an electric field can be generated; the electric field forms an electric field area at the front side of the dust collection surface 122, and the pollutants 200 in the electric field area will be polarized; the polarized pollutants 200 move towards the dust collection surface 122 under the action of Coulomb force until the pollutants 200 are adsorbed on the dust collection surface 122. Under the adsorption effect, the concentration of the pollutants 200 in the electric field area decreases; and under the effect of concentration difference, the pollutants 200 outside the electric field area migrate to the electric field area with a low concentration, and thus, the concentration of the pollutants 200 in the entire environment is reduced and the air purification effect is achieved.

Compared with the internal purification solution, without the limitation of an internal structure, the area of the exposed dust collection surface 122 can be enlarged more easily, to improve the purification capacity and the purification efficiency of the air purification equipment 100 through a large-area dust collection surface 122; moreover, the front side of the exposed dust collection surface 122 is not easily blocked, and this is conducive to expanding the coverage area of the electric field area, to further improve the purification capacity and the purification efficiency of air purification equipment 100, and thus solve the problems of insufficient purification capacity and low purification efficiency in related technologies. At the same time, the difficulty of cleaning the exposed dust collection surface 122 is relatively low, and a user can directly wipe off the pollutants 200 on the exposed dust collection surface 122 to avoid excessive pollutants 200 adhering to the dust collection surface 122, and thus, the problems of difficult cleaning and poor user experience in related technologies are solved.

Meanwhile, the noise generated by the dust collection assembly 120 when powered on is relatively small, and this can further improve the user experience.

[0071] In an embodiment, the dust collection assembly 120 provided in the present application can actively adsorb the pollutants 200 in the air through the electric field generated by the dust collection assembly 120 itself, the present application does not need a circulating airflow to achieve an air purification function and thus saves the space for arranging an air duct and a fan, and this provides a convenient condition for the miniaturization design and the lightweight design of the air purification equipment 100.

[0085] Disposing the dust collection assembly 120 in a plate shape helps increase the total area of the exposed dust collection surface 122, and thus, the purification capacity and the purification efficiency of the air purification equipment 100 are improved by increasing the exposed area of the dust collection surface 122.

[0086] In an embodiment, the shapes of the cross section of the plate-shaped dust collection assembly 120 comprise a rectangular shape, a curved shape and a circular shape.

[0087] As shown in FIG. 1, in some embodiments of the present application, the base 110 comprises a slot 1102, and the dust collection assembly 120 is partially inserted into the slot 1102.

[0088] In the embodiment, the slot 1102 is provided in the base 110, and the opening of the slot 1102 is at the top of the base 110; the shape of the slot 1102 is adapted to the shape of the outer contour of the dust collection assembly 120; during the use, the assembling of the dust collection assembly 120 can be accomplished by inserting the dust collection assembly 120 into the slot 1102. Thus, the slot 1102 can play a role of positioning the dust collection assembly 120, to ensure that the dust collection assembly 120 can be fixed at a predetermined working position.

[0089] Meanwhile, the dust collection assembly 120 can be disassembled and assembled through simple plugging and unplugging actions, and this helps reduce the difficulty of cleaning the dust collection assembly 120; in an embodiment, a user can unplug the dust collection assembly 120 from the slot 1102 and re-insert it back into the slot 1102 after the wiping is accomplished.

[0091] As shown in FIG. 2, in some embodiments of the present application, the dust collection assembly 120 is connected to the base 110, and the entire dust collection assembly 120 is located outside the base 110.

[0092] In the embodiment, the dust collection assembly 120 is fixed above the base 110; after the dust collection assembly 120 is assembled, the entire dust collection assembly 120 is located outside the base 110, and the dust collection surface 122 on the dust collection assembly 120 is completely exposed outside the base 110, to prevent the base 110 from blocking the dust collection surface 122; therefore, the purification efficiency and the purification capacity of the air purification equipment 100 are improved by increasing the exposed area of the dust collection surface 122.

[0093] In an embodiment, the dust collection assembly 120 can be fixed to the outer side of the base 110 through a connecting member such as a screw, and can further be buckled to the outer side of the base 110 through a buckle.

The dust collection assembly 120 is mounted in the accommodating chamber, and the frame 150 can play a role of positioning, protecting and supporting the dust collection assembly 120, to lower the possibility of damaging the dust collection assembly 120 due to external impact.

[0096] On the above basis, the dust collection surface 122 on the dust collection assembly 120 is exposed through the window 1502; during a working process, the dust collection assembly 120 forms an electric field area at the front side of the window 1502; the pollutants 200 in the electric field area move towards the dust collection surface 122 at the inner side of the window 1502 under the action of Coulomb force and are finally captured by the dust collection surface 122; firstly, the window 1502 can reduce the probability of scraping and impacting the dust collection surface 122, and secondly, the window 1502 can play a role of gathering the pollutants 200 adsorbed on the dust collection surface 122 and blocking the airflow blowing towards the dust collection surface 122, to reduce the possibility of a secondary pollution caused by the pollutants 200 on the dust collection surface 122.

[0097] During a cleaning process, a user can directly wipe the pollutants 200 on the dust collection surface 122 at the inner side of the window 1502, and can further disassemble the frame 150 to perform a deep cleaning on the dust collection surface 122.

[0099] In the embodiment, the air purification equipment 100 further comprises the power supply component; one of the positive electrode and the negative electrode on the power supply component is connected to the dust collection assembly 120, and the other one is connected to the discharging component 144, and the polarity of the electric ions accumulated inside the dust collection assembly 120 is opposite to the polarity of the electric ions released by the discharging component 144. The electric ions released by the discharging component 144 will adhere to the pollutants 200 in the electric field area, and the pollutants 200 carry opposite electricity to the dust collection assembly 120, and thus, the adsorption force of the dust collection assembly 120 on the pollutants 200 is increased on the basis of the original Coulomb force, the pollutants 200 are made to accelerate movement towards the dust collection surface 122, thereby the adsorption capacity of the dust collection assembly 120 is enhanced, and this compensates for the shortcomings of electric field adsorption, and solves the problems in related technologies that the Coulomb force on the pollutants 200 does not meet a standard, the ability to capture the pollutants 200 is insufficient, and the purification effect is poor. Furthermore, the effects of optimizing the structure of the air purification equipment 100, enhancing the purification capacity of air purification equipment 100 and improving the user experience are achieved.

[0100] As shown in FIG. 3, in some embodiments of the present application, the discharging component 144 comprises a connecting end and a transmitting end; the connecting end is connected to a support 142, and the transmitting end is for discharging electricity.

[0101] In the embodiment, the discharging component 144 is a discharging needle, and the discharging needle comprises a connecting end and a transmitting end; the connecting end of the discharging needle is electrically connected to the power supply component, and the power supply component supplies power to the discharging needle through the connecting end; after being powered on, the discharging needle can release electric ions, and the electric ions can adhere to the pollutants 200 in the electric field area.

[0102] In an embodiment, the discharging component 144 comprises the discharging needle or a discharging brush.

[0104] In the embodiment, the dust collection assembly 120 and the discharging component 144 can be supplied with power independently to help achieve the split design of the dust collection assembly 120 and the discharging component 144. The dust collection assembly 120 is connected to the power supply through the first voltage regulator 170; under the voltage regulation of the first voltage regulator 170, the potential of the dust collection assembly 120 is higher than the ground potential, and a positive voltage is formed between the dust collection assembly 120 and a zero-pole. Correspondingly, the discharging component 144 is connected to the power supply through the second voltage regulator 180; under the voltage regulation of the second voltage regulator 180, the potential of the discharging component 144 is lower than the ground potential, and a negative voltage is formed between the discharging component 144 and the zero-pole; the discharging component 144 carrying the negative voltage can release negative ions into the air, this causes the pollutants 200 in the air to be negatively charged; after being negatively charged, the pollutants 200 will move towards the dust collection assembly 120 that is positively charged and are finally captured by the dust collection assembly 120, and thus the pollutants 200 in the air are removed. In some embodiments of the present application, the air purification equipment 100 further comprises a base 110, and the dust collection assembly 120 and the discharging component 144 are arranged on the base 110.

[0105] As shown in FIG. 3, in some embodiments of the present application, the air purification equipment 100 further comprises a support 142 provided on the base 110, and the discharging component 144 is provided on the support 142. The discharging component 144 comprises discharging needles, and there are multiple discharging needles; the multiple discharging needles are arranged side by side on the support 142.

[0106] In the embodiment, the air purification equipment 100 further comprises the support 142, and the support 142 is configured to position and support the discharging component 144. After the discharging component 144 is powered on, it can release electric ions towards the discharging port it faces.

[0107] There are multiple discharging needles provided on the support 142, and the multiple discharging needles are arranged side by side on the support 142. By arranging multiple discharging needles side by side on the support 142, the coverage range of the electric ions released by the discharging needles can be expanded, and thereby the overlap degree between the coverage area of the electric ions and the electric field area is improved, to increase the number of the electric ions released into the electric field area and lower the difficulty that the pollutants 200 adhere to the electric ions in the electric field area, and then the effect of improving the adsorption capacity of the dust collection assembly 120 for the pollutants 200 is achieved.

[0108] As shown in FIG. 7, in some embodiments of the present application, the dust collection assembly 120 comprises: protective plates 124, and the number of the protective plates 124 is N, N is an integer greater than 1, the N protective plates 124 are stacked, and two adjacent protective plates 124 are spaced apart from each other; a conductive component 126, provided between two adjacent protective plates 124, and the conductive component 126 is configured to generate the electric field when powered on; and the surface of the protective plate 124 facing away from the conductive component 126 is the dust collection surface 122.

[0109] In the embodiment, the structure of the dust collection assembly 120 is defined in detail. The dust collection assembly 120 comprises the protective plates 124 and the conductive component 126. There are multiple protective plates 124, and the multiple protective plates 124 are stacked along the thickness direction of the base 110, two adjacent protective plates 124 are spaced apart to form a gap between them. The conductive component 126 is provided in the gap between the two adjacent protective plates 124, and can generate an electric field after being powered on. On the multiple protective plates 124, the surface facing away from the conductive component 126 is the dust collection surface 122, for example, when the number of the protective plates 124 is two, the outer side surfaces of the two protective plates 124 form two dust collection surfaces 122; when the number of the protective plates 124 is three, the two surfaces on the middle protective plate 124 both face the conductive component 126 and do not form the dust collection surface 122; the outer side surfaces of the protective plates 124 located at two sides form two dust collection surfaces 122, i.e., increasing the number of the protective plates 124 will not increase the number of the dust collection surfaces 122.

[0110] In an embodiment, the air purification equipment 100 further comprises the power supply component, and the power supply component is provided in the base 110; the power supply component comprises a positive electrode and a negative electrode, and the conductive component 126 is connected to the positive electrode to supply a positive DC high voltage to the conductive component 126 through the power supply component. After the positive DC high voltage is supplied to the conductive component 126, a large number of negative ions can be stored in the conductive component 126, and thus an electric field is formed. After moving into the electric field area, the pollutants 200 are polarized under the action of the electric field and are adsorbed onto the dust collection surface 122, during the process of approaching the dust collection surface 122, the closer the distance to the dust collection surface 122 is, the stronger the adsorption force is; therefore, the pollutants 200 undergo a process of accelerating movement towards the dust collection surface 122.

[0111] On the above basis, the surface of the protective plate 124 facing the conductive component 126 is covered with a first conductive layer, and the electric field can be enhanced by providing the first conductive layer, to strengthen the adsorption capacity of the dust collection assembly 120 for the pollutants 200. In an embodiment, the first conductive layer is a barium carbonate coating.

[0112] In an embodiment, the protective plate 124 is a silicon dioxide tempered glass plate, and the silicon dioxide tempered glass plate has the advantages of high strength, strong corrosion resistance and insulation, and can provide a long-term and effective protection for the inside conductive component 126, and thus, the reliability of the dust collection assembly 120 is improved and the failure rate of the dust collection assembly 120 is reduced. At the same time, the insulation property can avoid the problem of electricity leakage of the dust collection assembly 120, and thus the safety of the dust collection assembly 120 is further improved.

[0113] In an embodiment, the conductive component 126 comprises a conductive wire and a second conductive layer; the conductive wire is electrically connected to the power supply component, and the second conductive layer is wrapped around the conductive wire. By setting the second conductive layer, the conductivity of the conductive component 126 can be further improved, and thus, the strength of the electric field is further improved, to enhance the adsorption capacity of the dust collection assembly 120 for the pollutants 200.

[0114] In an embodiment, the conductive wire is an aluminum wire, and the second conductive layer is a graphene coating.

[0115] In an embodiment, a conductive foam is further provided between two adjacent protective plates 124, and the conductive foam cooperates with the conductive wire and the second conductive layer to fill the gap between the two adjacent protective plates 124.

[0116] In the embodiment, the dust collection surface 122 is a plane, or the dust collection surface 122 is a smooth curved surface.

[0117] Disposing the dust collection surface 122 to be a plane can reduce the size of the dust collection assembly 120 in a thickness direction, and this helps achieve an ultra-thin design of the dust collection assembly 120, provides a convenient condition for the miniaturization design and the lightweight design of the air purification equipment 100, and reduces the difficulty of the indoor arrangement of the air purification equipment 100.

[0118] Disposing the dust collection surface 122 to be a smooth curved surface can firstly increase the area of the dust collection surface 122 to improve the adsorption capacity of the dust collection assembly 120 for the pollutants 200, and secondly, the smooth curved surface can expand the electric field area generated by the dust collection assembly 120, and thereby expand an effective adsorption range of the dust collection assembly 120.

[0119] As shown in FIG. 8, it shows an electric field area generated by the dust collection assembly 120 after it is powered on.

[0120] In a direction from far to near, the front side of the dust collection surface 122 is divided into multiple fan-shaped sub-regions.

[0121] ρ1 is the concentration value of the pollutants 200 in a first sub-region, ρ2 is the concentration value of the pollutants 200 in a second sub-region, ρ3 is the concentration value of the pollutants 200 in a third sub-region, and ρ4 is the concentration value of the pollutants 200 in a fourth sub-region.

[0122] And, ρ1 <ρ2<ρ3<ρ4.

[0123] The arrow d indicates a moving direction of the pollutants 200; V1 represents a moving speed of the pollutants 200 in the first sub-region; V2 represents a moving speed of the pollutants 200 in the second sub-region; V3 represents a moving speed of the pollutants 200 in the third sub-region, and V4 represents a moving speed of the pollutants 200 in the fourth sub-region.

[0124] And, V1>V2>V3>V4, i.e., the greater the concentration difference is, the faster the moving speed is.

[0125] As shown in FIG. 9, the air purification equipment 100 provided by the present application comprises the dust collection assembly 120, an ion wind assembly and the discharging component 144; the dust collection assembly 120 comprises the protective plates 124 and the conductive component 126; the protective plates 124 are disposed at both sides of the conductive component 126, and the material of the conductive component 126 is a metal conductive material or a non-metallic conductive material; a large specific area can be configured to store a large number of negative ions.

[0126] The metal conductive material comprises copper, aluminum, silver, iron, tin, gold, nickel, lead, magnesium, zinc, molybdenum, yttrium, tungsten and cobalt. The non-metallic conductive material comprises graphite and graphene. The material of the conductive component 126 can further be a composition or compound of the metal conductive material and / or the non-metallic conductive material. In some embodiments, the conductive component 126 is a graphene aluminum wire layer.

[0127] The material of the protective plate 124 can be at least one of glass, plastic, or rubber. The protective plate 124 can serve as an adsorption structure; by utilizing the Coulomb force between ions, when the adsorbed object approaches a "glass layer" carrying negative ions, an adsorption effect will be produced. The air pollutants 200 such as PM2.5, dust and volatile substances can move toward the protective plates 124 in the direction indicated by the arrow M, and then adsorb the air pollutants 200 onto the surface of the protective plates 124.

[0128] The ion wind assembly and / or the discharging component 144 can transport negative ions to the dust collection assembly 120 in the direction indicated by arrow N, and can emit an ion beam in the direction indicated by arrow O, and membrane breaking, sterilization, and detoxification are achieved through the ion beam.

[0129] Furthermore, based on the Coulomb's law, the calculation formula for Coulomb force is: F=K × Q1 × Q2 / r 2< , Q1 and Q2 are the charges of two objects respectively, r is the distance between the centers of the two objects (the distance between Q1 and Q2), K is a constant, K=8.987 × 10 9< , and the unit is N · m 2< / C 2< ; the Coulomb force is the interaction force between stationary charged bodies.

[0130] A charged body can be deemed to be composed of many point charges, and the interaction force between each pair of stationary point charges follows the Coulomb's law, and the Coulomb's law states that the magnitude of the interaction force between the two stationary point charges Q1 and Q2 in vacuum is directly proportional to the product of Q1 and Q2, and inversely proportional to the square of the distance r between the point charges Q1 and Q2, and the direction of the action force is along their connection line, where homocharges repel each other and heterocharges attract each other.

[0131] There is no free charge inside an ideal insulating medium, and there is always a small number of free charges inside an actual dielectric; various substances can further be basically regarded as objects in which the centers of positive and negative electrons overlap. In general, the positive and negative bound charges inside the dielectric not subjected to the action of an electric field cancel each other out everywhere on the average, and do not show electrical properties macroscopically. Under the action of an external electric field, the local movement of the bound charges leads to showing electrical properties macroscopically, charges appear on the surface of the dielectric and in uneven areas inside the dielectric. This phenomenon is called polarization, and the appearing charges are called polarized charges. The conductive component 126 generates an electric field, and polarized charges are generated by the substances (for example, the air pollutants 200, etc.) in the electric field. Then, based on the principle that heterocharges attract each other, these substances are adsorbed on the surface of the dust collection assembly 120.

[0132] Furthermore, the dust collection assembly 120 generates the electric field when powered on; the particles first move in the space based on the concentration difference, and when they reach the electric field area, they will be adsorbed by the dust collection assembly 120; there will always be a low concentration area near the dust collection assembly 120, and then the particles are made to move towards it.

[0133] The air pollutants 200 will be polarized when they move to the electric field area of the dust collection assembly 120, and thus are adsorbed onto the dust collection assembly 120, and will undergo a process of accelerating movement when they get close to the dust collection assembly 120.

[0134] The power supply component has a positive electrode and a negative electrode; one of the positive electrode and the negative electrode is connected to the dust collection assembly 120, and the other one is connected to the discharging component 144. The discharging component 144 releases electrons into the air, and the air pollutants 200 carry opposite electricity to the dust collection assembly 120 and are absorbed to the dust collection assembly 120 at an accelerated speed. The purification efficiency is improved, and meanwhile, the discharging component 144 charges the air pollutants 200 and thus has a sterilizing effect.

[0135] One of the positive electrode and the negative electrode of the power supply component is connected to an ion generating electrode of the ion wind assembly, and the other one is connected to an ion receiving electrode of the ion wind assembly; an airflow channel must be provided, the ion generating electrode and the ion receiving electrode are mounted in the airflow channel, the airflow is made to flow through and is then sterilized.
