Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and in particular to an air purification device. Background Art

[0002] In the related art, air purification equipment can adsorb dust and other particles in the air to achieve air purification effect. However, the adsorbed particles will adhere to the air purification equipment for a long time. If not handled in time, it is easy to cause secondary pollution and affect the adsorption capacity of the air purification equipment for particles. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] A first aspect of the present invention provides an air purification device.

[0005] A second aspect of the present invention provides an air purification device.

[0006] The first aspect of the present invention provides an air purification device, which includes: a dust collecting component, the dust collecting component including a dust collecting surface, the dust collecting component can generate an electric field when powered on, and the dust collecting surface is used to collect pollutants in the air through the electric field; a first cleaning component, which is arranged on the dust collecting surface and can move on the dust collecting surface, and the first cleaning component is used to peel off the pollutants on the dust collecting surface through movement.

[0007] The present application defines an air purification device, which is used to treat pollutants in the air to achieve the effect of reducing the content of pollutants in the air. The air purification device includes a base and a dust collection component, and the base is used to position, support and protect the dust collection component.

[0008] The dust collecting component includes a dust collecting surface, which is arranged in the base, and the base avoids the dust collecting surface so that the dust collecting surface can be exposed to the air. The dust collecting component can generate an electric field after being energized, and the electric field forms an electric field area on the front side of the dust collecting surface. The pollutants in the electric field area will be polarized, and the polarized pollutants will move toward the dust collecting surface under the action of Coulomb force until the pollutants are adsorbed on the dust collecting surface. Under this adsorption action, the concentration of pollutants in the electric field area is reduced, and under the action of the concentration difference, the pollutants outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of pollutants in the entire environment to achieve an air purification effect.

[0009] On this basis, the air purification device also includes a first cleaning component, which is arranged on the dust collecting assembly, and the first cleaning component can move relative to the dust collecting assembly on the dust collecting surface. During the movement of the first cleaning component, the first cleaning component can maintain contact with the dust collecting surface, thereby peeling off the pollutants attached to the dust collecting surface during the relative movement, thereby playing a role in cleaning the dust collecting surface. Specifically, when the user issues a cleaning instruction, or the air purification device enters the self-cleaning mode, the air purification device controls the first cleaning component to start moving to complete the self-cleaning of the dust collecting surface.

[0010] It can be seen that, by setting the first cleaning component, the present application enables the air purification device to process the pollutants attached to the dust collecting surface with the help of the moving cleaning component. On the one hand, it can avoid the pollutants attached to the dust collecting surface for a long time from falling off and causing secondary pollution. On the other hand, it can avoid the pollutants attached to a large area from reducing the pollutant adsorption capacity of the dust collecting component. On the other hand, it can save the user from manually wiping the dust collecting surface, thereby improving the user experience. Thereby solving the technical problems existing in the above-mentioned related technologies. And then achieving the technical effect of optimizing the structure of the air purification equipment, improving the practicality and reliability of the air purification equipment, and providing convenient conditions for users.

[0011] On this basis, the dust collection component proposed in this application collects pollutants through an electric field, and the collected pollutants adhere to the dust collection surface. After use, the pollutants can be removed by washing or wiping the dust collection surface, eliminating the need for frequent replacement of filter materials, thereby reducing the cost of using air purification equipment. At the same time, the noise generated by the dust collection component when powered on is relatively small, which can further improve the user experience.

[0012] Specifically, the dust collecting component proposed in this application can actively absorb pollutants in the air by means of the electric field generated by itself, without the need for circulating airflow to achieve the air purification function, thereby saving space for arranging air ducts and fans. Moreover, the dust collecting component that absorbs pollutants by electric field can be reused after cleaning operation, which saves the cost of consumables compared to the technical solution of collecting pollutants by filtering consumables, thereby achieving the technical effect of improving the practicality of air purification equipment.

[0013] Among them, the pollutants mentioned in this application are mainly solid particle pollutants. Solid particle pollutants in the air include dust, smoke, particulate matter, bacteria, viruses, etc. Their diameters vary and can generally be divided into the following categories according to their diameters:

[0014] Visible particles: particles with a diameter of 10 microns or less, whose presence can be seen, such as dust, pollen, human dandruff, etc.

[0015] Fine particulate matter: Particles with a diameter of less than or equal to 2.5 microns, which cannot be seen by the naked eye but have a greater impact on human health, such as automobile exhaust and factory waste gas.

[0016] Ultrafine particles: particles with a diameter of 0.1 microns or less, which cannot be seen by the naked eye, but can penetrate deep into the human respiratory tract and have a greater impact on human health, such as viruses and bacteria.

[0017] Specifically, the first cleaning component includes structures such as a brush, a rubber strip, and an electrostatic strip.

[0018] In addition, the air purification device in the above technical solution provided by the present invention may also have the following additional technical features:

[0019] In some technical solutions of the present invention, optionally, the first cleaning component is adsorbed on the dust collecting surface, and the air purification device further includes: a moving component, which is arranged on the first cleaning component, and the moving component is used to drive the first cleaning component to move on the dust collecting surface.

[0020] In this technical solution, the first cleaning component is adsorbed on the dust collecting surface, and when the dust collecting surface is arranged vertically, the first cleaning component can stay on the dust collecting surface by adsorption force. On this basis, the first cleaning component is also provided with a moving component, which can drive the first cleaning component to move on the dust collecting surface. During the moving process, the first cleaning component peels off the pollutants on its movement track to complete the self-cleaning of the dust collecting surface.

[0021] By adsorbing the first cleaning component on the dust collecting surface, the positioning, guiding and connecting structures between the first cleaning component and the dust collecting assembly can be eliminated, thereby reducing the structural complexity of the dust collecting assembly and reducing the cost of the air purification device. By providing a moving component, the first cleaning component adsorbed on the dust collecting surface has the ability to move forward by itself, thereby realizing automatic cleaning of the dust collecting surface.

[0022] Specifically, after the air purification device turns on the self-cleaning mode, the moving component is controlled to drive the first cleaning component to move along a predetermined trajectory on the dust collecting surface. The predetermined trajectory covers the entire dust collecting surface, thereby ensuring that the first cleaning component can clean the entire area of ​​the dust collecting surface and avoid cleaning dead corners.

[0023] Specifically, the moving component includes a wheel body, and the first cleaning component can be driven to move on the dust collecting surface by controlling the rotation of the wheel body, wherein the wheel body can rotate relative to the first cleaning component to adjust the moving direction of the first cleaning component by controlling the rotation of the wheel body.

[0024] Specifically, the moving component includes a first magnetic component and a second magnetic component, the first magnetic component and the second magnetic component attract each other, the first magnetic component is connected to the first cleaning component, and the second magnetic component is arranged on the dust collecting component and is located on the inner side of the dust collecting surface. When the self-cleaning mode is turned on, the second magnetic component is controlled to move, and through magnetic attraction, the first magnetic component moves synchronously with the second magnetic component, and at the same time drives the first cleaning component to move on the dust collecting surface, thereby realizing self-cleaning of the dust collecting surface.

[0025] In some technical solutions of the present invention, optionally, the first cleaning component is slidably connected to the dust collecting assembly; the first cleaning component can reciprocate along the first direction.

[0026] In this technical solution, the first cleaning component is slidably connected to the dust collecting assembly. After the first cleaning component is assembled on the dust collecting assembly, the first cleaning component can slide back and forth along the first direction on the dust collecting assembly. During the sliding process of the first cleaning component, the first cleaning component that is in contact with the dust collecting surface peels off the pollutants on the dust collecting surface. The sliding track of the first cleaning component covers the dust collecting surface. During a single reciprocating sliding process, the first cleaning component can clean the dust collecting surface twice in different directions to ensure that the sliding first cleaning component can peel off the pollutants on the dust collecting surface.

[0027] The sliding connection method has the advantages of low connection structure complexity and simple movement form. It can reduce the structural complexity of the air purification equipment and reduce costs on the basis of meeting the sliding cleaning requirements of the first cleaning component. At the same time, the sliding connection has strong movement reliability and a low probability of interference and jamming, which is conducive to reducing the failure rate of the first cleaning component and improving the stability of the air purification equipment.

[0028] Specifically, the first cleaning component can be manually operated by the user, and when the dust collecting surface needs to be cleaned, the user can push and pull the first cleaning component. The first cleaning component can also be driven by a motor and a transmission mechanism to achieve automatic cleaning of the dust collecting surface.

[0029] Specifically, the sliding connection between the first cleaning component and the dust collecting assembly can be achieved through a guide rail and a first slider. Specifically, the guide rail is arranged on the dust collecting assembly and avoids the dust collecting surface. The first slider is arranged on the first cleaning component and can slide along the guide rail.

[0030] The first cleaning component and the dust collecting component can also be slidably connected by a lead screw and a second slider. Specifically, the lead screw is arranged on the dust collecting component and the lead screw avoids the dust collecting surface. The second slider is connected to the first cleaning component, and the second slider is sleeved on the lead screw and meshed with the external thread of the lead screw. Rotating the lead screw can drive the second slider and the first cleaning component to slide along the lead screw.

[0031] In some technical solutions of the present invention, optionally, the first cleaning component is in a strip shape, and the extending direction of the first cleaning component is the second direction; the first direction is perpendicular to the second direction.

[0032] In this technical solution, the sliding connection method of the above-mentioned technical solution is adopted. The first cleaning component is in the shape of a strip, and the specific first cleaning component can be selected as a strip brush or a rubber strip. The extension direction of the first cleaning component is the second direction, and the extension direction corresponds to the length direction of the strip first cleaning component. On this basis, the first direction is perpendicular to the second direction, so that the pollutants on the dust collecting surface are swept by the strip first cleaning component.

[0033] By defining the above structure, the cleaning coverage area of ​​the first cleaning component can be expanded, so as to reduce the size and material of the first cleaning component on the basis of meeting the cleaning requirements of the dust collecting surface, thereby achieving the technical effect of improving the cleaning reliability of the first cleaning component and reducing production costs.

[0034] Specifically, when the dust collecting surface is rectangular, the extension direction of the first cleaning component is consistent with the length direction of the dust collecting surface, and when the dust collecting surface needs to be cleaned, the first cleaning component is driven to slide along the width direction of the dust collecting surface. Alternatively, the extension direction of the first cleaning component is consistent with the width direction of the dust collecting surface, and when the dust collecting surface needs to be cleaned, the first cleaning component is driven to slide along the length direction of the dust collecting surface.

[0035] In some technical solutions of the present invention, optionally, the first cleaning component is rotatably connected to the dust collecting assembly.

[0036] In this technical solution, the first cleaning component is rotatably connected to the dust collecting assembly. When the dust collecting surface needs to be cleaned, the first cleaning component is controlled to swing on the dust collecting surface, so that the dust collecting surface within the swinging range is repeatedly cleaned by the swinging first cleaning component.

[0037] By setting a swinging first cleaning component, a part of the dust collecting surface can be cleaned multiple times and at a high frequency to ensure the cleanliness of the local area and ensure that the area can maintain a strong adsorption effect on pollutants. This can achieve the technical effect of optimizing the structure of the first cleaning component, improving the cleaning effect of the first cleaning component, and improving the pollutant adsorption capacity of the air purifier.

[0038] Specifically, the partial area is the central area of ​​the dust collecting surface.

[0039] In some technical solutions of the present invention, optionally, the air purification device further includes: a driving component, which is arranged in the dust collecting component and connected to the first cleaning component, and the driving component is used to drive the first cleaning component to move.

[0040] In this technical solution, the air purification device also includes a driving component, which is fixed on the dust collecting component, and the driving end of the driving component is connected to the first cleaning component. After power is turned on, the driving component is used to drive the first cleaning component to move relative to the dust collecting component, so as to clean the pollutants on the dust collecting surface through the moving first cleaning component.

[0041] By providing a driving component, automatic control of the first cleaning component can be achieved, eliminating the need for a user to manually control the movement of the first cleaning component, thereby achieving the technical effect of improving the degree of automation and intelligence of the air purification equipment.

[0042] Specifically, when the first cleaning component is connected to the dust collecting assembly through the guide rail and the first slider, the driving component can be selected as a telescopic cylinder, and the telescopic cylinder drives the first cleaning component to slide along the guide rail through a telescopic action.

[0043] When the first cleaning component is connected to the dust collecting assembly via the lead screw and the second sliding block, the driving component may be a motor, and the motor drives the lead screw to rotate.

[0044] When the first cleaning component is rotationally connected to the dust collecting assembly, the driving component can be selected to be a motor, which is connected to the rotating shaft and drives the rotating shaft and the first cleaning component to rotate synchronously.

[0045] In some technical solutions of the present invention, optionally, the air purification device also includes: a sensor, which is arranged in the dust collecting component, and the sensor is used to detect the pollutant content on the dust collecting surface; a controller, which is connected to the sensor and the driving component, and the controller is used to control the operation of the driving component according to the pollutant content.

[0046] In this technical solution, the air purification device also includes a sensor and a controller. The sensor is arranged on the dust collecting component, and the sensor is arranged opposite to the dust collecting surface. The sensor can detect the pollutant content on the dust collecting surface. The controller is connected to the sensor and the driving component, and the controller can control the operation of the driving component according to the pollutant content. Specifically, when the pollutant content is greater than the threshold, the driving component is controlled to drive the first cleaning component to work, and when the pollutant content is less than or equal to the threshold, the driving component is controlled to standby. In order to realize the automatic cleaning of the dust collecting surface, the technical effect of improving the degree of automation and intelligence of the air purification equipment is achieved.

[0047] Specifically, the sensor is a light sensor, which determines the degree of pollutant adhesion on the dust collecting surface by detecting the light transmittance of the dust collecting surface, and correspondingly determines the pollutant content.

[0048] In some technical solutions of the present invention, optionally, the air purification device further includes: a water supply component, which is arranged on the dust collecting component and / or the first cleaning component, and the water supply component is used to supply water to the dust collecting surface.

[0049] In this technical solution, the air purification device also includes a water supply component, which is arranged on the dust collecting assembly and / or the first cleaning component. The water supply component is connected to a water tank or an external water source. When the dust collecting surface needs to be cleaned, the water supply component is controlled to spray liquid onto the dust collecting surface to cooperate with the sliding first cleaning component to clean off the pollutants attached to the dust collecting surface, ensuring that the stubborn pollutants on the dust collecting surface can be peeled off.

[0050] By providing a water supply component, pollutants on the dust collecting surface can be flushed away by means of liquid sprayed on the dust collecting surface, thereby improving the cleaning effect of the dust collecting surface.

[0051] In some technical schemes of the present invention, optionally, the dust collecting assembly includes: a guard plate, the number of the guard plates is N, N is an integer greater than 1, the N guard plates are stacked, and two adjacent guard plates are spaced apart; a conductive component, arranged between two adjacent guard plates, the conductive component is used to generate an electric field when power is supplied, and the surface of the guard plate facing away from the conductive component is a dust collecting surface.

[0052] In this technical solution, the structure of the dust collecting assembly is refined. Specifically, the dust collecting assembly includes a guard plate and a conductive component. Specifically, there are multiple guard plates, and the multiple guard plates are stacked along the thickness direction of the base, and two adjacent guard plates are spaced apart to form a gap between two adjacent guard plates. The conductive component is arranged in the gap between two adjacent guard plates, and the conductive component can generate an electric field after being energized. On the multiple guard plates, the surface facing away from the conductive part is the dust collecting surface. For example, when the number of guard plates is two, the outer side surfaces of the two guard plates form two dust collecting surfaces. When the number of guard plates is three, the two middle guard plates are both facing the conductive component and do not form a dust collecting surface. The outer side surfaces of the guard plates on both sides form two dust collecting surfaces, that is, increasing the number of guard plates will not increase the number of dust collecting surfaces.

[0053] Specifically, the air purification device also includes a power supply component, which is arranged in the base. The power supply component includes a positive electrode and a negative electrode. The conductive component is connected to the positive electrode so that positive DC high voltage is passed to the conductive component through the power supply component. After the positive DC high voltage is passed to the conductive component, a large number of negative ions can be stored in the conductive component, thereby forming an electric field. After the pollutants move to the electric field area, they are polarized under the action of the electric field and are adsorbed onto the dust collecting surface. In the process of approaching the dust collecting surface, the closer the distance to the dust collecting surface, the stronger the adsorption force, so the pollutants have a process of accelerating movement toward the dust collecting surface.

[0054] On this basis, the surface of the guard plate facing the conductive component is covered with a first conductive layer, and the first conductive layer can enhance the electric field to strengthen the adsorption capacity of the dust collecting component to pollutants. Specifically, the first conductive layer is a barium carbonate coating.

[0055] Specifically, the protective plate is a silicon dioxide tempered glass plate, which has the advantages of high strength, strong corrosion resistance and insulation, and can provide long-term and effective protection for the internal conductive parts, thereby improving the reliability of the dust collection component and reducing the failure rate of the dust collection component. At the same time, the insulation property can avoid the leakage problem of the dust collection component, thereby improving the safety of the dust collection component.

[0056] Specifically, the conductive component includes a conductive wire and a second conductive layer. The conductive wire is electrically connected to the power supply component. The second conductive layer is wrapped around the outside of the conductive wire. By setting the second conductive layer, the conductive performance of the conductive component can be further improved, thereby increasing the strength of the electric field to enhance the dust collection component's ability to adsorb pollutants.

[0057] Specifically, the conductive wire is an aluminum wire, and the second conductive layer is a graphene coating.

[0058] Specifically, a conductive foam is arranged between two adjacent guard plates, and the conductive foam cooperates with the conductive thread and the second conductive layer to fill the gap between the two adjacent guard plates.

[0059] In some technical solutions of the present invention, optionally, the air purification device also includes: a base, and the dust collecting component is arranged on the base.

[0060] In this technical solution, the air purification device also includes a base, which is used to position, support and protect the dust collecting component.

[0061] Specifically, a slot is provided on the base, and the shape of the slot is adapted to the outer contour of the dust collecting component so that the dust collecting component can be partially inserted into the slot. After the dust collecting component is assembled, a small part of the dust collecting component at the bottom is embedded in the slot to provide a limit for the dust collecting component, and most of the dust collecting component at the top is exposed above the slot to absorb pollutants in the air by exposing the dust collecting surface to the air.

[0062] In some technical solutions of the present invention, optionally, the dust collecting assembly is detachably connected to the base, and the air purification device also includes: a first electrical connection component, which is arranged on the base; and a second electrical connection component, which is arranged on the dust collecting assembly and docked with the first electrical connection component.

[0063] A first electrical connection component is provided in the slot of the base, and a second electrical connection component is correspondingly provided at the bottom of the dust collection component. After the dust collection component is inserted into the slot, the first electrical connection component and the second electrical connection component are connected, and the power supply component in the base can supply power to the dust collection component through the first electrical connection component and the second electrical connection component, so that the dust collection component absorbs pollutants through the electric field. Correspondingly, after the dust collection component is pulled out of the slot, the first electrical connection component and the second electrical connection component are disconnected.

[0064] When the dust collection component needs to be cleaned or replaced, the user can remove the dust collection component from the slot. By limiting the detachable installation method, on the one hand, convenient conditions can be provided for the maintenance and replacement of the dust collection component, and on the other hand, the split structure can reduce the difficulty of transportation and warehousing.

[0065] In some technical solutions of the present invention, optionally, the air purification device also includes: a storage component, which is arranged on the base, and in the height direction of the air purification device, the storage component is located below the dust collecting component, and the storage component is used to store pollutants peeled off by the first cleaning component on the dust collecting surface.

[0066] In the technical solution, the air purification device further includes a storage component, which is arranged on the base and below the dust collecting assembly. When the first cleaning component cleans the dust collecting surface by moving, the pollutants peeled off by the first cleaning component fall into the storage component below, so that the pollutants cleaned by the storage component are collected.

[0067] Similarly, when liquid is sprayed onto the dust collecting surface through the water supply component, the storage component can also collect the liquid dripping along the dust collecting surface to simultaneously complete the collection of the cleaning liquid.

[0068] By providing a storage component, the stripped pollutants and cleaning liquid can be prevented from causing secondary pollution to the environment, and the pollutants and cleaning liquid can be prevented from damaging other electrical structures in the air purifier, thereby achieving the technical effect of improving the practicality and reliability of the air purifier and reducing the failure rate of the air purifier.

[0069] In some technical solutions of the present invention, optionally, the air purification device also includes: a discharge component, which is arranged on the base, and the discharge component is used to discharge toward the area facing the dust collecting surface.

[0070] In this technical solution, a discharge port is also provided on the base, and the discharge port is connected to the cavity in the base. On this basis, the air purification device also includes a discharge component, the discharge end of the discharge component is opposite to the discharge port, and the discharge component can discharge to the outside of the base through the discharge port after being energized.

[0071] Specifically, one of the positive and negative electrodes on the power supply component is connected to the dust collection component, and the other is connected to the discharge component, so that the ions accumulated inside the dust collection component and the ions released by the discharge component have opposite polarities. The ions released by the discharge component will adhere to the pollutants in the air, so that the pollutants carry the opposite charge to the dust collection component, thereby accelerating the movement of the pollutants to the dust collection surface, thereby achieving the technical effect of improving the adsorption capacity of the dust collection component, improving the air purification capacity and air purification efficiency.

[0072] At the same time, the ions released by the discharge component can also play a bactericidal role to reduce the content of toxic substances in the air and protect the health of users.

[0073] In some technical solutions of the present invention, optionally, the discharge component avoids the first cleaning component; the discharge component avoids the area between the dust collecting surface and the storage component.

[0074] In this technical solution, the position of the discharge component needs to meet the following conditions: the discharge component avoids the movement trajectory of the first cleaning component, and the discharge component avoids the area between the dust collecting surface and the storage component. By setting the discharge component to avoid the first cleaning component, interference between the first cleaning component and the discharge component can be avoided, ensuring that the first cleaning component and the discharge component can work normally. By setting the discharge component to avoid the area between the dust collecting surface and the storage component, on the one hand, it can prevent the stripped pollutants and cleaning liquid from entering the discharge component, thereby extending the service life of the discharge component, and on the other hand, it can prevent the charged pollutants from re-attaching to the dust collecting surface, thereby improving the cleaning effect of the dust collecting surface.

[0075] In some technical solutions of the present invention, optionally, the base includes a cavity and a discharge port, and the discharge assembly includes: a bracket disposed in the cavity; a discharge component disposed in the bracket, and the discharge port and the discharge component are arranged opposite to each other.

[0076] In this technical solution, the discharge assembly includes a bracket and a discharge component, the bracket is arranged in a cavity in the base and connected to the base, and the bracket is used to position and support the discharge component. When the discharge component is energized, it can release ions toward the discharge port it faces.

[0077] Specifically, the discharge component is a discharge needle, a first end of the discharge needle is electrically connected to the power supply component, and a second end of the discharge needle faces the discharge port. After power is applied, the discharge needle can release ions toward the discharge port.

[0078] In some technical solutions of the present invention, optionally, the base includes a cavity, a first air flow port and a second air flow port, the first air flow port is connected with the second air flow port through the cavity, and also includes: an ion wind component disposed in the cavity.

[0079] In this technical solution, a first air flow opening and a second air flow opening are also provided on the base, and the first air flow opening is connected with the second air flow opening through the cavity, that is, the first air flow opening, the cavity and the second air flow opening are combined into an air flow passage.

[0080] On this basis, the air purification device also includes an ion wind component, which is arranged in the cavity. When the ion wind component is energized, ions that move in a direction are generated inside the component. The ions can drive the nearby gas to flow during the directional movement, thereby generating a corresponding directional airflow. On the one hand, this airflow can accelerate the air flow near the air purification device, thereby cooperating with the dust collection component and the discharge component to improve the air purification capacity. On the other hand, the directional flow of ions can sterilize the pollutants in the driven airflow to reduce the content of toxic substances in the air and protect the health of users.

[0081] In some technical solutions of the present invention, optionally, the ion wind component includes: a frame, including an air duct, the end of the air duct is opposite to the first air flow outlet; an ion emitting component, arranged in the air duct; and an ion receiving component, arranged in the air duct and opposite to the ion emitting component.

[0082] In this technical solution, the structure of the ion wind component is refined, and the ion wind component includes a frame, an ion emitting component and an ion receiving component. The frame is arranged in the cavity, and the frame is connected to the base. A through air duct is arranged in the frame, and the outlet end of the air duct is opposite to the first air flow outlet. The ion emitting component and the ion receiving component are arranged in the frame, and the frame can provide support and protection for the ion emitting component and the ion receiving component. Among them, the ion receiving component is arranged at a position close to the outlet end of the air duct, and the ion receiving component is arranged at a position close to the inlet end of the air duct.

[0083] One of the ion emitting component and the ion receiving component is connected to the positive electrode of the power supply component, and the other is connected to the negative electrode of the power supply component. After power is turned on, the ion emitting component releases ions, and the released ions are captured by the ion receiving component, thereby forming directional flow of ions and directional flow of airflow. The airflow flows out of the base through the outlet end of the air duct and the first airflow outlet to form a cycle in conjunction with the second airflow outlet.

[0084] In some technical solutions of the present invention, optionally, the dust collecting surface is a plane; or the dust collecting surface is a smooth curved surface.

[0085] In this technical solution, the dust collecting surface is a plane, or the dust collecting surface is a smooth curved surface. By setting the dust collecting surface as a plane, it is conducive to realizing an ultra-thin design of the dust collecting component, providing convenient conditions for the miniaturization and lightweight design of the air purification equipment.

[0086] By setting the dust collecting surface as a smooth curved surface, the pollutant adsorption range of the dust collecting surface can be expanded through the smooth curved surface, thereby improving the pollutant adsorption capacity of the air purification device.

[0087] The second aspect of the present invention provides an air purification device, which includes: a base; a dust collecting component, which is arranged on the base and can move on the base, the dust collecting component includes a dust collecting surface, the dust collecting component can generate an electric field when powered on, and the dust collecting surface is used to collect pollutants in the air through the electric field; a second cleaning component, which is arranged on the base and contacts the dust collecting surface, and the second cleaning component is used to peel off the pollutants on the dust collecting surface during the movement of the dust collecting component.

[0088] The present application defines an air purification device, which is used to treat pollutants in the air to achieve the effect of reducing the content of pollutants in the air. The air purification device includes a base and a dust collection component, and the base is used to position, support and protect the dust collection component.

[0089] The dust collecting component includes a dust collecting surface, which is arranged in the base, and the base avoids the dust collecting surface so that the dust collecting surface can be exposed to the air. The dust collecting component can generate an electric field after being energized, and the electric field forms an electric field area on the front side of the dust collecting surface. The pollutants in the electric field area will be polarized, and the polarized pollutants will move toward the dust collecting surface under the action of Coulomb force until the pollutants are adsorbed on the dust collecting surface. Under this adsorption action, the concentration of pollutants in the electric field area is reduced, and under the action of the concentration difference, the pollutants outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of pollutants in the entire environment to achieve an air purification effect. Among them, the dust collecting component can move relative to the base, and the dust collecting component can be disassembled and assembled by sliding.

[0090] On this basis, the air purification device is further provided with a second cleaning component, which is mounted on the base and is located on the sliding track of the dust collecting surface. When the dust collecting component moves relative to the base, the second cleaning component keeps in contact with the dust collecting surface, thereby peeling off the pollutants on the dust collecting surface through the relative movement trend.

[0091] Specifically, a slot is provided on the base, the dust collecting assembly is detachably arranged in the slot, and the second cleaning component is installed at the opening of the slot. After the dust collecting assembly is inserted into the slot, the second cleaning component contacts the edge of the dust collecting surface. In the process of driving the dust collecting assembly to slide relative to the body through push-pull action, the second cleaning component slides on the dust collecting surface and peels off the pollutants attached to the dust collecting surface through contact and sliding.

[0092] For example, when removing the dust collecting component from the slot, the second cleaning component contacts and sweeps across the entire dust collecting surface to remove pollutants attached to the dust collecting surface, thereby reducing the difficulty of subsequent cleaning and wiping. Correspondingly, when assembling the dust collecting component, the cleaning unit can also contact and sweep across the entire dust collecting surface to remove dust attached to the dust collecting surface through the second cleaning component, thereby preventing the original dust on the dust collecting surface from affecting the pollutant adsorption effect.

[0093] It can be seen that, by setting a second cleaning component, the present application enables the air purification device to process the pollutants attached to the dust collecting surface with the help of the moving dust collecting component and the second cleaning component that maintains contact, so that the disassembly and assembly process of the dust collecting component and the cleaning process of the dust collecting surface can be performed simultaneously. On the one hand, it avoids the secondary pollution caused by the fall-off of pollutants that have been attached to the dust collecting surface for a long time, on the other hand, it can avoid the pollutants attached over a large area from reducing the pollutant adsorption capacity of the dust collecting component, and on the other hand, it eliminates the need for users to manually wipe the dust collecting surface, thereby improving the user experience. Thereby, the technical problems existing in the above-mentioned related technologies are solved. Then, the technical effect of optimizing the structure of the air purification equipment, improving the practicality and reliability of the air purification equipment, and providing convenient conditions for users is achieved.

[0094] Specifically, the second cleaning component includes structures such as a brush, a rubber strip, and an electrostatic strip.

[0095] In some technical solutions of the present invention, optionally, the dust collecting component includes a first position, and the air purification device also includes: a third electrical connection component, which is arranged on the base; a fourth electrical connection component, which is arranged on the dust collecting component, and when the dust collecting component is located in the first position, the third electrical connection component and the fourth electrical connection component are connected.

[0096] In this technical solution, a third electrical connection component is provided in the slot of the base, and a fourth electrical connection component is correspondingly provided at the bottom of the dust collecting component. After the dust collecting component is inserted into the slot, the third electrical connection component and the fourth electrical connection component are connected, and the power supply component in the base can supply power to the dust collecting component through the third electrical connection component and the fourth electrical connection component, so that the dust collecting component absorbs pollutants through the electric field. Correspondingly, after the dust collecting component is pulled out of the slot, the third electrical connection component and the fourth electrical connection component are disconnected.

[0097] When the dust collection component needs to be cleaned or replaced, the user can remove the dust collection component from the slot. By limiting the detachable installation method, on the one hand, convenient conditions can be provided for the maintenance and replacement of the dust collection component, and on the other hand, the split structure can reduce the difficulty of transportation and warehousing.

DETAILED DESCRIPTION

[0122] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0123] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0124] Refer to the following Figures 1 to 20 Air purification devices according to some embodiments of the present invention are described.

[0125] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, one embodiment of the present application proposes an air purification device 100, which includes: a dust collecting component 120, the dust collecting component 120 includes a dust collecting surface 122, the dust collecting component 120 can generate an electric field when powered on, and the dust collecting surface 122 is used to collect pollutants in the air through the electric field; a first cleaning component 170, which is arranged on the dust collecting surface 122 and can move on the dust collecting surface 122, and the first cleaning component 170 is used to peel off the pollutants on the dust collecting surface 122 by movement.

[0126] The present application defines an air purification device 100, which is used to treat pollutants in the air to reduce the content of pollutants in the air. The air purification device 100 includes a base 110 and a dust collection component 120, and the base 110 is used to position, support and protect the dust collection component 120.

[0127] The dust collecting component 120 includes a dust collecting surface 122, and the dust collecting component 120 is arranged in the base 110, and the base 110 avoids the dust collecting surface 122 so that the dust collecting surface 122 can be exposed to the air. The dust collecting component 120 can generate an electric field after being energized, and the electric field forms an electric field area in front of the dust collecting surface 122. The pollutants in the electric field area will be polarized, and the polarized pollutants move toward the dust collecting surface 122 under the action of the Coulomb force until the pollutants are adsorbed on the dust collecting surface 122. Under this adsorption action, the concentration of pollutants in the electric field area is reduced, and under the action of the concentration difference, the pollutants outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of pollutants in the entire environment to achieve an air purification effect.

[0128] On this basis, the air purification device 100 also includes a first cleaning component 170, which is arranged on the dust collection assembly 120, and the first cleaning component 170 can move relative to the dust collection assembly 120 on the dust collection surface 122. During the movement of the first cleaning component 170, the first cleaning component 170 can maintain contact with the dust collection surface 122, so as to peel off the pollutants attached to the dust collection surface 122 during the relative movement, and play a role in cleaning the dust collection surface 122. Specifically, when the user issues a cleaning instruction, or the air purification device 100 enters the self-cleaning mode, the air purification device 100 controls the first cleaning component 170 to start moving to complete the self-cleaning of the dust collection surface 122.

[0129] It can be seen that, by setting the first cleaning component 170, the present application enables the air purification device 100 to process the pollutants attached to the dust collecting surface 122 with the help of the moving cleaning component. On the one hand, it can avoid the pollutants attached to the dust collecting surface 122 for a long time from falling off and causing secondary pollution. On the other hand, it can avoid the pollutants attached to a large area from reducing the pollutant adsorption capacity of the dust collecting component 120. On the other hand, it can avoid the user from manually wiping the dust collecting surface 122, thereby improving the user experience. Thereby solving the technical problems existing in the above-mentioned related technologies. And then achieving the technical effect of optimizing the structure of the air purification device 100, improving the practicality and reliability of the air purification device 100, and providing convenient conditions for users.

[0130] On this basis, the dust collecting assembly 120 proposed in the present application collects pollutants through an electric field, and the collected pollutants adhere to the dust collecting surface 122. After use, the pollutants can be removed by washing or wiping the dust collecting surface 122, eliminating the need for frequent replacement of filter materials, thereby reducing the use cost of the air purification device 100. At the same time, the noise generated by the dust collecting assembly 120 when powered on is relatively small, which can further enhance the user experience.

[0131] Specifically, the dust collecting component 120 proposed in the present application can actively absorb pollutants in the air by means of the electric field generated by itself, without the need for circulating airflow to achieve the air purification function, thereby eliminating the space for arranging the air duct 1522 and the fan. In addition, the dust collecting component 120 that absorbs pollutants by the electric field can be reused after the cleaning operation, which saves the cost of consumables compared to the embodiment of collecting pollutants by filtering consumables, thereby achieving the technical effect of improving the practicality of the air purification device 100.

[0132] Among them, the pollutants mentioned in this application are mainly solid particle pollutants. Solid particle pollutants in the air include dust, smoke, particulate matter, bacteria, viruses, etc. Their diameters vary and can generally be divided into the following categories according to their diameters:

[0133] Visible particles: particles with a diameter of 10 microns or less, whose presence can be seen, such as dust, pollen, human dandruff, etc.

[0134] Fine particulate matter: Particles with a diameter of less than or equal to 2.5 microns, which cannot be seen by the naked eye but have a greater impact on human health, such as automobile exhaust and factory waste gas.

[0135] Ultrafine particles: particles with a diameter of 0.1 microns or less, which cannot be seen by the naked eye, but can penetrate deep into the human respiratory tract and have a greater impact on human health, such as viruses and bacteria.

[0136] Specifically, the first cleaning component 170 includes structures such as a brush, a rubber strip, and an electrostatic strip.

[0137] like Figure 1 As shown, in some embodiments of the present invention, optionally, the first cleaning component 170 is adsorbed on the dust collecting surface 122, and the air purification device 100 also includes: a moving component 172, which is arranged on the first cleaning component 170, and the moving component 172 is used to drive the first cleaning component 170 to move on the dust collecting surface 122.

[0138] In this embodiment, the first cleaning component 170 is adsorbed on the dust collecting surface 122. When the dust collecting surface 122 is arranged vertically, the first cleaning component 170 can be stationed on the dust collecting surface 122 by adsorption force. On this basis, the first cleaning component 170 is also provided with a moving component 172, which can drive the first cleaning component 170 to move on the dust collecting surface 122. The first cleaning component 170 peels off the pollutants on its movement track during the moving process to complete the self-cleaning of the dust collecting surface 122.

[0139] By adsorbing the first cleaning component 170 on the dust collecting surface 122, the positioning, guiding and connecting structures between the first cleaning component 170 and the dust collecting assembly 120 can be eliminated, thereby reducing the structural complexity of the dust collecting assembly 120 and reducing the cost of the air purification device 100. By providing the moving component 172, the first cleaning component 170 adsorbed on the dust collecting surface 122 has the ability to move forward by itself, thereby realizing automatic cleaning of the dust collecting surface 122.

[0140] Specifically, after the air purification device 100 turns on the self-cleaning mode, the first cleaning component 170 is driven to move along a predetermined trajectory on the dust collecting surface 122 by controlling the moving component 172. The predetermined trajectory covers the entire dust collecting surface 122, thereby ensuring that the first cleaning component 170 can clean the entire area on the dust collecting surface 122 to avoid cleaning dead corners.

[0141] Specifically, the moving component 172 includes a wheel body, which can drive the first cleaning component 170 to move on the dust collecting surface 122 by controlling the rotation of the wheel body, wherein the wheel body can rotate relative to the first cleaning component 170 to adjust the moving direction of the first cleaning component 170 by controlling the rotation of the wheel body.

[0142] Specifically, the traveling component 172 includes a first magnetic component and a second magnetic component, the first magnetic component and the second magnetic component attract each other, the first magnetic component is connected to the first cleaning component 170, and the second magnetic component is arranged on the dust collecting assembly 120 and is located inside the dust collecting surface 122. When the self-cleaning mode is turned on, the second magnetic component is controlled to move, and through magnetic attraction, the first magnetic component moves synchronously with the second magnetic component, and at the same time drives the first cleaning component 170 to move on the dust collecting surface 122, thereby realizing self-cleaning of the dust collecting surface 122.

[0143] like Figure 2and Figure 3 As shown, in some embodiments of the present invention, optionally, the first cleaning component 170 is slidably connected to the dust collecting assembly 120; the first cleaning component 170 can reciprocate along the first direction. Figure 2 The arrows a and Figure 3 The arrow b in FIG. 1 shows the first direction in two different implementations.

[0144] In this embodiment, the first cleaning component 170 is slidably connected to the dust collecting assembly 120. After the first cleaning component 170 is assembled on the dust collecting assembly 120, the first cleaning component 170 can slide back and forth along the first direction on the dust collecting assembly 120. During the sliding process of the first cleaning component 170, the first cleaning component 170 that keeps in contact with the dust collecting surface 122 peels off the pollutants on the dust collecting surface 122. The sliding track of the first cleaning component 170 covers the dust collecting surface 122. During a single reciprocating sliding process, the first cleaning component 170 can clean the dust collecting surface 122 twice in different directions, ensuring that the sliding first cleaning component 170 can peel off the pollutants on the dust collecting surface 122.

[0145] The sliding connection has the advantages of low connection structure complexity and simple movement form, which can reduce the structural complexity of the air purification device 100 and reduce costs on the basis of meeting the sliding cleaning requirements of the first cleaning component 170. At the same time, the sliding connection has strong movement reliability, and the probability of interference and jamming is low, which is conducive to reducing the failure rate of the first cleaning component 170 and improving the stability of the air purification device 100.

[0146] Specifically, the first cleaning component 170 can be manually operated by the user. When the dust collecting surface 122 needs to be cleaned, the user can push and pull the first cleaning component 170. The first cleaning component 170 can also be driven by a motor and a transmission mechanism to achieve automatic cleaning of the dust collecting surface 122.

[0147] Specifically, the sliding connection between the first cleaning component 170 and the dust collecting assembly 120 can be achieved through a guide rail and a first slider. Specifically, the guide rail is arranged on the dust collecting assembly 120 and the guide rail avoids the dust collecting surface 122. The first slider is arranged on the first cleaning component 170 and the first slider can slide along the guide rail.

[0148] The sliding connection between the first cleaning component 170 and the dust collecting component 120 can also be achieved through a lead screw and a second slider. Specifically, the lead screw is arranged on the dust collecting component 120 and the lead screw avoids the dust collecting surface 122. The second slider is connected to the first cleaning component 170, and the second slider is sleeved on the lead screw and meshed with the external thread of the lead screw. Rotating the lead screw can drive the second slider and the first cleaning component 170 to slide along the lead screw.

[0149] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, optionally, the first cleaning member 170 is in a strip shape, and the extending direction of the first cleaning member 170 is the second direction; the first direction is perpendicular to the second direction.

[0150] In this embodiment, the sliding connection method of the previous embodiment is adopted. The first cleaning member 170 is in a strip shape, and the first cleaning member 170 can be a strip brush or a rubber strip. The extension direction of the first cleaning member 170 is the second direction, and the extension direction corresponds to the length direction of the strip first cleaning member 170. On this basis, the first direction is perpendicular to the second direction, so that the pollutants on the dust collecting surface 122 are swept by the strip first cleaning member 170.

[0151] By defining the above structure, the cleaning coverage area of ​​the first cleaning component 170 can be expanded, so as to reduce the size and material of the first cleaning component 170 while meeting the cleaning requirements of the dust collecting surface 122, thereby achieving the technical effect of improving the cleaning reliability of the first cleaning component 170 and reducing production costs.

[0152] Specifically, when the dust collecting surface 122 is rectangular, the extension direction of the first cleaning component 170 is consistent with the length direction of the dust collecting surface 122. When the dust collecting surface 122 needs to be cleaned, the first cleaning component 170 is driven to slide along the width direction of the dust collecting surface 122. Alternatively, the extension direction of the first cleaning component 170 is consistent with the width direction of the dust collecting surface 122. When the dust collecting surface 122 needs to be cleaned, the first cleaning component 170 is driven to slide along the length direction of the dust collecting surface 122.

[0153] like Figure 4 As shown, in some embodiments of the present invention, optionally, the first cleaning component 170 is rotatably connected to the dust collecting assembly 120. Figure 4 The arrow c in FIG. 1 shows the swinging direction of the first cleaning member.

[0154] In this embodiment, the first cleaning component 170 is rotatably connected to the dust collecting assembly 120. When the dust collecting surface 122 needs to be cleaned, the first cleaning component 170 is controlled to swing on the dust collecting surface 122, so that the dust collecting surface 122 within the swinging range is repeatedly cleaned by the swinging first cleaning component 170.

[0155] By setting the swinging first cleaning component 170, a partial area on the dust collecting surface 122 can be cleaned multiple times and at a high frequency to ensure the cleanliness of the local area and ensure that the area can maintain a strong adsorption effect on pollutants. This achieves the technical effect of optimizing the structure of the first cleaning component 170, improving the cleaning effect of the first cleaning component 170, and improving the pollutant adsorption capacity of the air purifier.

[0156] Specifically, the partial area is the central area of ​​the dust collecting surface 122 .

[0157] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the present invention, optionally, the air purification device 100 further includes: a driving component 174, which is disposed in the dust collecting assembly 120 and connected to the first cleaning component 170, and the driving component 174 is used to drive the first cleaning component 170 to move.

[0158] In this embodiment, the air purification device 100 also includes a driving component 174, which is fixed on the dust collecting component 120, and the driving end of the driving component 174 is connected to the first cleaning component 170. After power is turned on, the driving component 174 is used to drive the first cleaning component 170 to move relative to the dust collecting component 120, so as to clean the pollutants on the dust collecting surface 122 through the moving first cleaning component 170.

[0159] By providing the driving component 174, automatic control of the first cleaning component 170 can be achieved, eliminating the need for the user to manually control the movement of the first cleaning component 170, thereby achieving the technical effect of improving the automation and intelligence of the air purification device 100.

[0160] Specifically, when the first cleaning component 170 is connected to the dust collecting assembly 120 via the guide rail and the first slider, the driving component 174 can be selected as a telescopic cylinder, which drives the first cleaning component 170 to slide along the guide rail through a telescopic action.

[0161] When the first cleaning component 170 is connected to the dust collecting assembly 120 via a lead screw and a second slider, the driving component 174 can be selected to be a motor, and the motor drives the lead screw to rotate.

[0162] When the first cleaning component 170 is rotationally connected to the dust collecting assembly 120 , the driving component 174 can be selected to be a motor, which is connected to the rotating shaft and drives the rotating shaft and the first cleaning component 170 to rotate synchronously.

[0163] like Figure 4 and Fig. 9 As shown, in some embodiments of the present invention, optionally, the air purification device 100 also includes: a sensor 162, which is arranged on the dust collecting component 120, and the sensor 162 is used to detect the pollutant content on the dust collecting surface 122; a controller 160, which is connected to the sensor 162 and the driving component 174, and the controller 160 is used to control the operation of the driving component 174 according to the pollutant content.

[0164] In this embodiment, the air purification device 100 also includes a sensor 162 and a controller 160. The sensor 162 is arranged on the dust collecting assembly 120, and the sensor 162 is arranged relative to the dust collecting surface 122. The sensor 162 can detect the pollutant content on the dust collecting surface 122. The controller 160 is connected to the sensor 162 and the driving component 174, and the controller 160 can control the operation of the driving component 174 according to the pollutant content. Specifically, when the pollutant content is greater than the threshold value, the driving component 174 is controlled to drive the first cleaning component 170 to work, and when the pollutant content is less than or equal to the threshold value, the driving component 174 is controlled to standby. In order to realize the automatic cleaning of the dust collecting surface 122, the technical effect of improving the automation and intelligence of the air purification device 100 is achieved.

[0165] Specifically, the sensor 162 is a light sensor 162 , and the light sensor 162 determines the degree of pollutant adhesion on the dust collecting surface 122 by detecting the light transmittance of the dust collecting surface 122 , and correspondingly determines the pollutant content.

[0166] like Figure 4 As shown, in some embodiments of the present invention, optionally, the air purification device 100 also includes: a water supply component 176, which is provided in the dust collecting assembly 120 and / or the first cleaning component 170, and the water supply component 176 is used to supply water to the dust collecting surface 122.

[0167] In this embodiment, the air purification device 100 also includes a water supply component 176, which is arranged on the dust collecting assembly 120 and / or the first cleaning component 170. The water supply component 176 is connected to a water tank or an external water source. When the dust collecting surface 122 needs to be cleaned, the water supply component 176 is controlled to spray liquid onto the dust collecting surface 122 to cooperate with the sliding first cleaning component 170 to clean off the pollutants attached to the dust collecting surface 122, ensuring that the stubborn pollutants on the dust collecting surface 122 can be peeled off.

[0168] By providing the water supply component 176 , pollutants on the dust collecting surface 122 can be flushed away by means of liquid sprayed on the dust collecting surface 122 , thereby improving the cleaning effect of the dust collecting surface 122 .

[0169] Specifically, the water supply component 176 can be controlled to work alone to flush away the pollutants on the dust collecting surface 122 through the cleaning liquid.

[0170] The first cleaning member 170 may also be controlled to work alone, so that the first cleaning member 170 can clean the pollutants on the dust collecting surface 122 .

[0171] The first cleaning component 170 and the water supply component 176 may also be controlled to work in coordination to enhance the cleaning effect of the dust collecting surface 122 .

[0172] like Fig.13 , Fig.14 and Fig.15 As shown, in some embodiments of the present invention, optionally, the dust collecting assembly 120 includes: a guard plate 124, the number of the guard plates 124 is N, N is an integer greater than 1, the N guard plates 124 are stacked, and two adjacent guard plates 124 are spaced apart; a conductive component 126, disposed between two adjacent guard plates 124, the conductive component 126 is used to generate an electric field when power is supplied, and the surface of the guard plate 124 facing away from the conductive component 126 is the dust collecting surface 122.

[0173] In this embodiment, the structure of the dust collecting assembly 120 is refined. Specifically, the dust collecting assembly 120 includes a guard plate 124 and a conductive component 126. Specifically, the number of the guard plates 124 is multiple, and the multiple guard plates 124 are stacked along the thickness direction of the base 110, and the two adjacent guard plates 124 are spaced apart to form a gap between the two adjacent guard plates 124. The conductive component 126 is arranged in the gap between the two adjacent guard plates 124, and the conductive component 126 can generate an electric field after being energized. On the multiple guard plates 124, the surface facing away from the conductive part is the dust collecting surface 122. For example, when the number of the guard plates 124 is two, the outer side surfaces of the two guard plates 124 form two dust collecting surfaces 122. When the number of the guard plates 124 is three, the two middle guard plates 124 both face the conductive part 126 and do not form dust collecting surfaces 122. The outer side surfaces of the guard plates 124 on both sides form two dust collecting surfaces 122, that is, increasing the number of guard plates 124 will not increase the number of dust collecting surfaces 122.

[0174] Specifically, the air purification device 100 also includes a power supply component, which is arranged in the base 110. The power supply component includes a positive electrode and a negative electrode. The conductive component 126 is connected to the positive electrode so that positive DC high voltage is passed to the conductive component 126 through the power supply component. After the conductive component 126 is passed with positive DC high voltage, a large amount of negative ions can be stored in the conductive component 126, thereby forming an electric field. After the pollutants move to the electric field area, they are polarized under the action of the electric field, and are adsorbed onto the dust collecting surface 122. In the process of approaching the dust collecting surface 122, the closer the distance to the dust collecting surface 122, the stronger the adsorption force, so the pollutants have a process of accelerating movement toward the dust collecting surface 122.

[0175] On this basis, the surface of the guard plate 124 facing the conductive component 126 is covered with a first conductive layer, and the first conductive layer can enhance the electric field to strengthen the adsorption capacity of the dust collecting assembly 120 for pollutants. Specifically, the first conductive layer is a barium carbonate coating.

[0176] Specifically, the protective plate 124 is a silicon dioxide tempered glass plate, which has the advantages of high strength, strong corrosion resistance, and insulation, and can provide long-term and effective protection for the internal conductive components 126, thereby improving the reliability of the dust collecting assembly 120 and reducing the failure rate of the dust collecting assembly 120. At the same time, the insulation property can prevent the dust collecting assembly 120 from having leakage problems, thereby improving the safety of the dust collecting assembly 120.

[0177] Specifically, the conductive component 126 includes 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 outside of the conductive wire. By setting the second conductive layer, the conductive performance of the conductive component 126 can be further improved, thereby increasing the strength of the electric field to enhance the dust collection component 120's ability to adsorb pollutants.

[0178] Specifically, the conductive wire is an aluminum wire, and the second conductive layer is a graphene coating.

[0179] Specifically, a conductive foam is disposed between two adjacent guard plates 124 , and the conductive foam cooperates with the conductive thread and the second conductive layer to fill the gap between the two adjacent guard plates 124 .

[0180] like Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, in some embodiments of the present invention, optionally, the air purification device 100 also includes: a base 110, and the dust collecting assembly 120 is arranged on the base 110.

[0181] In this embodiment, the air purification device 100 further includes a base 110 , which is used to position, support and protect the dust collecting assembly 120 .

[0182] Specifically, a slot 112 is provided on the base 110, and the shape of the slot 112 is adapted to the outer contour of the dust collecting component 120 so that the dust collecting component 120 can be partially inserted into the slot 112. After the dust collecting component 120 is assembled, a small part of the dust collecting component 120 at the bottom is embedded in the slot 112 to provide a limit for the dust collecting component 120, and most of the dust collecting component 120 at the top is exposed above the slot 112 to absorb pollutants in the air by exposing the dust collecting surface 122 to the air.

[0183] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, optionally, the dust collecting assembly 120 is detachably connected to the base 110, and the air purification device 100 also includes: a first electrical connection component 114, which is arranged on the base 110; a second electrical connection component 123, which is arranged on the dust collecting assembly 120 and is docked with the first electrical connection component 114.

[0184] A first electrical connection component 114 is provided in the slot 112 of the base 110, and a second electrical connection component 123 is correspondingly provided at the bottom of the dust collection component 120. After the dust collection component 120 is inserted into the slot 112, the first electrical connection component 114 and the second electrical connection component 123 are docked, and the power supply component in the base 110 can supply power to the dust collection component 120 through the first electrical connection component 114 and the second electrical connection component 123, so that the dust collection component 120 absorbs pollutants through the electric field. Correspondingly, after the dust collection component 120 is pulled out of the slot 112, the first electrical connection component 114 and the second electrical connection component 123 are disconnected.

[0185] When the dust collecting component 120 needs to be cleaned or replaced, the user can remove the dust collecting component 120 from the slot 112. By limiting the detachable installation method, on the one hand, convenient conditions can be provided for the maintenance and replacement of the dust collecting component 120, and on the other hand, the split structure can reduce the difficulty of transportation and warehousing.

[0186] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the present invention, optionally, the air purification device 100 also includes: a storage component 178, which is arranged on the base 110. In the height direction of the air purification device 100, the storage component 178 is located below the dust collecting component 120, and the storage component 178 is used to store the pollutants peeled off by the first cleaning component 170 on the dust collecting surface 122.

[0187] In this embodiment, the air purification device 100 further includes a storage component 178, which is disposed on the base 110 and below the dust collecting assembly 120. When the first cleaning component 170 cleans the dust collecting surface 122 by moving, the pollutants peeled off by the first cleaning component 170 fall into the storage component 178 below, so that the pollutants cleaned by the storage component 178 are collected.

[0188] Similarly, when liquid is sprayed onto the dust collecting surface 122 through the water supply component 176, the storage component 178 can also collect the liquid dripping along the dust collecting surface 122 to simultaneously complete the collection of the cleaning liquid.

[0189] By providing the storage component 178, it is possible to prevent the stripped pollutants and cleaning liquid from causing secondary pollution to the environment, and it is also possible to prevent the pollutants and cleaning liquid from damaging other electrical structures in the air purifier, thereby achieving the technical effect of improving the practicality and reliability of the air purifier and reducing the failure rate of the air purifier.

[0190] like Fig. 9 , Fig.12 , Fig.13 and Fig.14As shown, in some embodiments of the present invention, optionally, the air purification device 100 further includes: a discharge component 140, which is disposed on the base 110, and the discharge component 140 is used to discharge toward the area facing the dust collecting surface 122.

[0191] In this embodiment, the base 110 is further provided with a discharge port 116, which is connected to a cavity 117 in the base 110. On this basis, the air purification device 100 further includes a discharge component 140, the discharge end of the discharge component 140 is opposite to the discharge port 116, and the discharge component 140 can discharge to the outside of the base 110 through the discharge port 116 after being energized.

[0192] Specifically, one of the positive and negative electrodes on the power supply component is connected to the dust collecting component 120, and the other is connected to the discharge component 140, so that the ions accumulated inside the dust collecting component 120 and the ions released by the discharge component 140 have opposite polarities. The ions released by the discharge component 140 will adhere to the pollutants in the air, so that the pollutants carry the opposite charge to the dust collecting component 120, thereby accelerating the movement of the pollutants toward the dust collecting surface 122, thereby achieving the technical effect of improving the adsorption capacity of the dust collecting component 120, improving the air purification capacity and air purification efficiency.

[0193] At the same time, the ions released by the discharge component 140 can also play a sterilizing role to reduce the content of toxic substances in the air and protect the health of users.

[0194] like Fig. 9 , Fig.12 , Fig.13 and Fig.14 As shown, in some embodiments of the present invention, optionally, the discharge component 140 avoids the first cleaning component 170; the discharge component 140 avoids the area between the dust collecting surface 122 and the storage component 178.

[0195] In this embodiment, the position of the discharge assembly 140 needs to meet the following conditions: the discharge assembly 140 avoids the movement track of the first cleaning component 170, and the discharge assembly 140 avoids the area between the dust collecting surface 122 and the storage component 178. By setting the discharge assembly 140 to avoid the first cleaning component 170, it is possible to avoid interference between the first cleaning component 170 and the discharge assembly 140, thereby ensuring that the first cleaning component 170 and the discharge assembly 140 can work normally. By setting the discharge assembly 140 to avoid the area between the dust collecting surface 122 and the storage component 178, on the one hand, it is possible to prevent the stripped pollutants and cleaning liquid from entering the discharge assembly 140, thereby extending the service life of the discharge assembly 140, and on the other hand, it is possible to prevent the charged pollutants from reattaching to the dust collecting surface 122, thereby improving the cleaning effect of the dust collecting surface 122.

[0196] like Fig. 9 , Fig.12 and Fig.13 As shown, in some embodiments of the present invention, optionally, the base 110 includes a cavity 117 and a discharge port 116, and the discharge assembly 140 includes: a bracket 142, which is disposed in the cavity 117; a discharge component 144, which is disposed in the bracket 142, and the discharge port 116 is arranged opposite to the discharge component 144.

[0197] In this embodiment, the discharge assembly 140 includes a bracket 142 and a discharge component 144. The bracket 142 is disposed in the cavity 117 in the base 110 and connected to the base 110. The bracket 142 is used to position and support the discharge component 144. When the discharge component 144 is energized, it can release ions toward the discharge port 116 it faces.

[0198] Specifically, the discharge component 140 is a discharge needle, a first end of the discharge needle is electrically connected to the power supply component, and a second end of the discharge needle faces the discharge port 116 . After being energized, the discharge needle can release ions toward the discharge port 116 .

[0199] like Fig. 9 and Fig.13 As shown, in some embodiments of the present invention, optionally, the base 110 includes a cavity 117, a first air flow outlet 118 and a second air flow outlet 119, the first air flow outlet 118 is connected to the second air flow outlet 119 through the cavity 117, and also includes: an ion wind component 150, which is arranged in the cavity 117.

[0200] In this embodiment, the base 110 is further provided with a first air flow opening 118 and a second air flow opening 119 , and the first air flow opening 118 is connected with the second air flow opening 119 through the cavity 117 , that is, the first air flow opening 118 , the cavity 117 and the second air flow opening 119 are combined into an air flow passage.

[0201] On this basis, the air purification device 100 also includes an ion wind component 150, which is arranged in the cavity 117. After the ion wind component 150 is powered on, ionized ions are generated inside it, and the ions can drive the nearby gas flow during the directional movement, thereby generating a corresponding directional flow of airflow. On the one hand, the airflow can accelerate the air flow near the air purification device 100, thereby cooperating with the dust collection component 120 and the discharge component 140 to improve the air purification capacity. On the other hand, the ionized flow can sterilize the pollutants in the driven airflow to reduce the content of toxic substances in the air and protect the health of users.

[0202] like Fig.16 , Fig.17 , Fig.18 , Fig.19 and Fig. 20As shown, in some embodiments of the present invention, optionally, the ion wind component 150 includes: a frame 152, including an air duct 1522, the end of the air duct 1522 is opposite to the first air flow outlet 118; an ion emitting component 154, disposed in the air duct 1522; and an ion receiving component 156, disposed in the air duct 1522 and opposite to the ion emitting component 154.

[0203] In this embodiment, the structure of the ion wind component 150 is refined, and the ion wind component 150 includes a frame 152, an ion emitting component 154 and an ion receiving component 156. The frame 152 is arranged in the cavity 117, and the frame 152 is connected to the base 110. A through air duct 1522 is arranged in the frame 152, and the outlet end of the air duct 1522 is opposite to the first air flow outlet 118. The ion emitting component 154 and the ion receiving component 156 are arranged in the frame 152, and the frame 152 can provide support and protection for the ion emitting component 154 and the ion receiving component 156. Among them, the ion receiving component 156 is arranged at a position close to the outlet end of the air duct 1522, and the ion receiving component 156 is arranged at a position close to the inlet end of the air duct 1522.

[0204] One of the ion emitting component 154 and the ion receiving component 156 is connected to the positive electrode of the power supply component, and the other is connected to the negative electrode of the power supply component. After power is turned on, the ion emitting component 154 releases ions, and the released ions are captured by the ion receiving component 156, thereby forming directional flow of ions and directional flow of air. The airflow flows out of the base 110 through the outlet end of the air duct 1522 and the first airflow port 118 to form a cycle in conjunction with the second airflow port 119.

[0205] like Fig. 9 and Fig.10 As shown, in some embodiments of the present invention, optionally, the dust collecting surface 122 is a plane; or the dust collecting surface 122 is a smooth curved surface.

[0206] In this embodiment, the dust collecting surface 122 is a plane, or the dust collecting surface 122 is a smooth curved surface. By setting the dust collecting surface 122 as a plane, it is beneficial to realize the ultra-thin design of the dust collecting component 120, and provide convenient conditions for the miniaturization and lightweight design of the air purification device 100.

[0207] By setting the dust collecting surface 122 as a smooth curved surface, the pollutant adsorption range of the dust collecting surface 122 can be expanded through the smooth curved surface, thereby improving the pollutant adsorption capacity of the air purification device 100.

[0208] like Figure 7 and Figure 8As shown, the second aspect of the present invention provides an air purification device 100, which includes: a base 110; a dust collecting component 120, which is disposed on the base 110 and can move on the base 110, and the dust collecting component 120 includes a dust collecting surface 122, and the dust collecting component 120 can generate an electric field when powered on, and the dust collecting surface 122 is used to collect pollutants in the air through the electric field; a second cleaning component 179, which is disposed on the base 110 and contacts the dust collecting surface 122, and the second cleaning component 179 is used to peel off the pollutants on the dust collecting surface 122 during the movement of the dust collecting component 120.

[0209] The present application defines an air purification device 100, which is used to treat pollutants in the air to reduce the content of pollutants in the air. The air purification device 100 includes a base 110 and a dust collection component 120, and the base 110 is used to position, support and protect the dust collection component 120.

[0210] The dust collecting assembly 120 includes a dust collecting surface 122, and the dust collecting assembly 120 is arranged in the base 110, and the base 110 avoids the dust collecting surface 122 so that the dust collecting surface 122 can be exposed to the air. The dust collecting assembly 120 can generate an electric field after being energized, and the electric field forms an electric field area in front of the dust collecting surface 122. The pollutants in the electric field area will be polarized, and the polarized pollutants move toward the dust collecting surface 122 under the action of the Coulomb force until the pollutants are adsorbed on the dust collecting surface 122. Under this adsorption, the concentration of pollutants in the electric field area is reduced, and under the action of the concentration difference, the pollutants outside the electric field area migrate to the electric field area with low concentration, thereby reducing the concentration of pollutants in the entire environment to achieve an air purification effect. Among them, the dust collecting assembly 120 can move relative to the base 110, and the dust collecting assembly 120 can be disassembled and assembled by sliding.

[0211] On this basis, the air purification device 100 is further provided with a second cleaning component 179, which is mounted on the base 110 and is located on the sliding track of the dust collecting surface 122. During the movement of the dust collecting assembly 120 relative to the base 110, the second cleaning component 179 maintains contact with the dust collecting surface 122, thereby stripping the pollutants on the dust collecting surface 122 through the relative movement trend.

[0212] Specifically, a slot 112 is provided on the base 110, and the dust collecting assembly 120 is detachably arranged in the slot 112. The second cleaning component 179 is installed at the opening of the slot 112. After the dust collecting assembly 120 is inserted into the slot 112, the second cleaning component 179 contacts the edge of the dust collecting surface 122. In the process of driving the dust collecting assembly 120 to slide relative to the body through the push-pull action, the second cleaning component 179 slides on the dust collecting surface 122 and peels off the pollutants attached to the dust collecting surface 122 through contact and sliding.

[0213] For example, in the process of removing the dust collecting assembly 120 from the slot 112, the second cleaning component 179 contacts and sweeps across the entire dust collecting surface 122 to peel off the pollutants attached to the dust collecting surface 122, thereby reducing the difficulty of subsequent cleaning and wiping. Correspondingly, in the process of assembling the dust collecting assembly 120, the cleaning unit can also contact and sweep across the entire dust collecting surface 122 to peel off the dust attached to the dust collecting surface 122 through the second cleaning component 179, thereby preventing the original dust on the dust collecting surface 122 from affecting the pollutant adsorption effect.

[0214] It can be seen that, by setting the second cleaning component 179, the present application enables the air purification device 100 to process the pollutants attached to the dust collecting surface 122 with the help of the moving dust collecting component 120 and the second cleaning component 179 that maintains contact, so that the disassembly and assembly process of the dust collecting component 120 and the cleaning process of the dust collecting surface 122 can be executed synchronously. On the one hand, it can avoid the pollutants that have been attached to the dust collecting surface 122 for a long time from falling off and causing secondary pollution. On the other hand, it can avoid the pollutants attached to a large area from reducing the pollutant adsorption capacity of the dust collecting component 120. On the other hand, it can eliminate the need for users to manually wipe the dust collecting surface 122, thereby improving the user experience. Thereby solving the technical problems existing in the above-mentioned related technologies. And then achieving the technical effect of optimizing the structure of the air purification device 100, improving the practicality and reliability of the air purification device 100, and providing convenient conditions for users.

[0215] Specifically, the second cleaning component 179 includes structures such as a brush, a rubber strip, and an electrostatic strip.

[0216] like Figure 7 and Figure 8 As shown, in some embodiments of the present invention, optionally, the dust collecting component 120 includes a first position, and the air purification device 100 also includes: a third electrical connection component 115, which is arranged on the base 110; a fourth electrical connection component 127, which is arranged on the dust collecting component 120, and when the dust collecting component 120 is located in the first position, the third electrical connection component 115 and the fourth electrical connection component 127 are connected.

[0217] In this embodiment, a third electrical connection component 115 is provided in the slot 112 of the base 110, and a fourth electrical connection component 127 is correspondingly provided at the bottom of the dust collection component 120. After the dust collection component 120 is inserted into the slot 112, the third electrical connection component 115 and the fourth electrical connection component 127 are docked, and the power supply component in the base 110 can supply power to the dust collection component 120 through the third electrical connection component 115 and the fourth electrical connection component 127, so that the dust collection component 120 absorbs pollutants through the electric field. Correspondingly, after the dust collection component 120 is pulled out of the slot 112, the third electrical connection component 115 and the fourth electrical connection component 127 are disconnected.

[0218] When the dust collecting component 120 needs to be cleaned or replaced, the user can remove the dust collecting component 120 from the slot 112. By limiting the detachable installation method, on the one hand, convenient conditions can be provided for the maintenance and replacement of the dust collecting component 120, and on the other hand, the split structure can reduce the difficulty of transportation and warehousing.
