[0052] Currently, electric purification devices are widely used in daily life. However, when in use, current electric purification devices are prone to particle escape, resulting in a low particle collection rate and affecting dust removal efficiency.

[0053] Referring to FIG. 1 , one embodiment of the present application provides an electric purification device 100 comprising a first pole assembly 10 and a second pole assembly 20 . The first pole assembly 10 is configured to form a first electric field within a dust collection space 11 through which a target medium passes, the first electric field being used to collect target particles in the target medium. The second pole assembly 20 is configured to generate a second electric field within the dust collection space 11 . The electric field force directions of the first electric field, the electric field force directions of the second electric field, and the movement direction of the target medium within the dust collection space 11 are arranged to intersect with each other.

[0054] In some embodiments, the electric field force direction of the first electric field is perpendicular to the electric field force direction of the second electric field, and the electric field force directions of the first electric field and the second electric field are respectively perpendicular to the movement direction of the target medium in the dust collecting space 11.

[0055] In some embodiments, the second pole assembly 20 is disposed on the first pole assembly 10 , and the second pole assembly 20 may be engaged with the first pole assembly 10 . In still other embodiments, the second pole assembly 20 may not be in contact with the first pole assembly 10 .

[0056] It should be noted that when the electric purification device 100 is applied to an air purifier, the target medium may be the air to be purified, and the target particles may be dust in the air. The following description is based on the electric purification device 100 being applied to an air purifier. Of course, the electric purification device 100 can also be applied to other purification equipment, which will not be described in detail here.

[0057] In some embodiments, a dust collection space 11 is formed within the first pole assembly 10. Specifically, the first pole assembly 10 includes a dust collection space 11. For example, the dust collection space 11 is the space enclosed by the side walls and bottom wall of the first pole assembly 10. The dust collection space 11 allows a target medium, such as air to be purified, to pass through. As the air passes through the dust collection space 11, the electric field forces of the first and second electric fields can be used to collect charged particles, such as dust, in the air, thereby purifying the air.

[0058] Specifically, the first pole assembly 10 forms a first electric field within the dust collection space 11, with the electric field force of the first electric field perpendicular to the direction of air entering the integrated space. As air passes through the dust collection space 11, the first electric field initially charges the particles entering the field. Under the influence of the electric field force, the charged particles move toward the first pole assembly 10, where they are collected.

[0059] However, the force exerted on the charged particles in their flow direction (i.e., the direction of movement of the target medium) may be greater than the attraction exerted by the first pole assembly 10. For example, when the wind speed of the air purifier is high, the force exerted on the charged particles in their flow direction by the airflow is greater than the attraction exerted by the first pole assembly 10. In this case, the charged particles may escape and fail to be collected by the first pole assembly 10, thus affecting the dust removal efficiency.

[0060] Based on this, by setting the second pole assembly 20, a superimposed second electric field is formed in the dust collecting space 11, and the electric field force direction of the second electric field is perpendicular to the electric field force direction of the first electric field and the direction of air entering the dust collecting space 11.

[0061] As charged particles move within the dust collection space 11, they are subjected to a first force component in the direction of movement, an attractive force from the first pole assembly 10, and a second force component applied by the second electric field. These three forces are perpendicular to each other. The combined effects of the first, attractive, and second forces increase the movement path of the charged particles within the dust collection space 11, causing them to gradually approach the first pole assembly 10 during movement and ultimately be collected there, thereby achieving dust removal.

[0062] Through the above structure, under the joint action of the superimposed first electric field and the second electric field, the movement path of the target particles in the dust collecting space 11 is increased, so that the target particles can move toward the direction close to the first pole assembly 10 in the dust collecting space 11, and finally be successfully collected on the first pole assembly 10, thereby reducing the probability of target particles escaping and improving the dust removal efficiency.

[0063] Referring to FIG. 2 , in some embodiments, the first electrode assembly 10 includes a repelling electrode 12 and a first grounding electrode 13 spaced apart along a first direction a. The repelling electrode 12 is connected to the positive electrode, and the first grounding electrode 13 is connected to the ground electrode. The first direction a is parallel to the direction of the electric field force of the first electric field.

[0064] Specifically, the repelling electrode 12 is connected to a sub-high voltage, and the first grounding electrode 13 is connected to the ground. Thus, the repelling electrode 12 is a positive electrode, and the first grounding electrode 13 is a negative electrode. When charged particles move between the repelling electrode 12 and the first grounding electrode 13, they are attracted by the first grounding electrode 13, causing the charged particles to be collected by the first grounding electrode 13, thereby achieving dust removal.

[0065] Furthermore, the repelling electrode 12 and the first grounding electrode 13 can each be configured as a flat plate structure perpendicular to the first direction a, and the repelling electrode 12 and the first grounding electrode 13 can be spaced apart along the first direction a, thereby forming a first electric field between the repelling electrode 12 and the first grounding electrode 13, and the direction of the electric field force of the first electric field is from the repelling electrode 12 to the first grounding electrode 13. When charged particles pass through the dust collection space 11, they are attracted by the first grounding electrode 13, so that the charged particles can move toward the first grounding electrode 13 under the action of the attraction and are ultimately collected on the first grounding electrode 13.

[0066] By setting up a repelling electrode 12 and a first grounding electrode 13, and connecting the repelling electrode 12 to the positive electrode and the first grounding electrode 13 to the negative electrode, a first electric field is formed between the repelling electrode 12 and the first grounding electrode 13, with the direction of the electric field force pointing from the repelling electrode 12 to the first grounding electrode 13. When passing through the dust collecting space 11, the target particles can move toward the first grounding electrode 13 under the attraction of the first grounding electrode 13, and thus be collected on the first grounding electrode 13, thereby successfully achieving dust removal.

[0067] As shown in FIG3 , in some embodiments, the repelling electrode 12 includes a main body 121 and an insulating layer 122 covering the outside of the main body 121 , and the main body 121 is used to connect to the positive electrode.

[0068] It should be noted that during the electrical purification process, if target particles with larger diameters enter the dust collecting space 11, they may hit the repelling electrode 12, causing abnormal discharge, sparking and electric shock sounds, affecting the use of the air purifier.

[0069] Therefore, coating the main body 121 of the repelling electrode 12 with an insulating layer 122 can effectively suppress abnormal discharge and sparking, increase the electric field, and reduce the generation of ozone.

[0070] In some embodiments, the body 121 includes a metal body, and / or the insulating layer 122 includes a rubber coating.

[0071] Specifically, the main body 121 is configured as a metal body, and the insulating layer 122 is configured as a rubber coating that insulates the exterior of the metal body. The metal body can be, but is not limited to, a steel sheet. This creates a fully encapsulated structure of polarized dielectric material, utilizing the principle of material polarization to address the "edge effect" discharge problem. Ultimately, by suppressing abnormal discharge, the electric field is enhanced, and ozone production is reduced.

[0072] Referring to Figures 2, 4, and 5, in some embodiments, the first electrode assembly 10 includes a plurality of repelling electrodes 12 and a plurality of first grounding electrodes 13. The repelling electrodes 12 and the first grounding electrodes 13 are spaced and staggered along a first direction a. The first electric field includes a plurality of first sub-electric fields, and any adjacent repelling electrodes 12 and first grounding electrodes 13 are used to form a first sub-electric field.

[0073] Each repelling electrode 12 and each first grounding electrode 13 are arranged parallel to each other and staggered along the first direction a. Each repelling electrode 12 is connected to a positive electrode, and each first grounding electrode 13 is connected to a ground electrode. Thus, each repelling electrode 12 forms a positive electrode, and the first grounding electrodes 13 located on either side of the repelling electrode 12 along the first direction a form negative electrodes. This forms a first sub-electric field between the repelling electrode 12 and the adjacent first grounding electrodes 13. All of the first sub-electric fields together form the first electric field, and the direction of the electric field force of the first electric field is directed from the repelling electrode 12 to the first grounding electrode 13 along the first direction a.

[0074] When the target medium passes through the dust collecting space 11, it can pass between each two adjacent repelling electrodes 12 and the first grounding electrode 13 respectively. In the process of passing through the adjacent repelling electrodes 12 and the first grounding electrodes 13, the target particles are adsorbed onto the corresponding first grounding electrodes 13, thereby achieving the purpose of dust removal.

[0075] By setting up multiple repelling electrodes 12 and multiple first grounding electrodes 13, and spacing and staggering the repelling electrodes 12 and the first grounding electrodes 13, the number of first electric fields can be increased, so that more target particles can enter the dust collecting space 11, thereby improving dust removal efficiency.

[0076] In some embodiments, the second pole assembly 20 includes a pole wire 21 and a second grounding electrode 22 spaced apart along the first direction a. The pole wire 21 is used to connect to the positive pole, and the second grounding electrode 22 is used as the grounding electrode.

[0077] Specifically, the electrode wire 21 can be, but is not limited to, a tungsten wire. The tungsten wire is connected to a high voltage, and the second grounding electrode 22 is connected to a ground electrode. The tungsten wire and the second grounding electrode 22 jointly form a second electric field, which is superimposed on the first electric field, and the direction of the electric field force of the second electric field is perpendicular to the direction of the electric field force of the first electric field and the direction in which the charged particles enter the dust collecting space 11.

[0078] When the airflow is subjected to greater force when the charged particles enter the dust collecting space 11, the movement path of the charged particles in the dust collecting space 11 can be increased under the joint action of the first electric field force and the second electric field force, so that the charged particles can move smoothly toward the first grounding electrode 13 in the dust collecting space 11, and finally be successfully collected on the first grounding electrode 13, thereby achieving the purpose of dust removal.

[0079] In some embodiments, the second pole assembly 20 includes a plurality of pole wires 21 and a plurality of second grounding electrodes 22, wherein each pole wire 21 and each second grounding electrode 22 are spaced and staggered along the first direction a. The second electric field includes a plurality of second sub-electric fields, and any adjacent pole wires 21 and second grounding electrodes 22 are used to form a second sub-electric field.

[0080] Specifically, each pole wire 21 and each second grounding electrode 22 are arranged parallel to each other and staggered along the first direction a. Each pole wire 21 is evenly connected to the positive pole, and each second grounding electrode 22 is evenly connected to the ground pole, so that each pole wire 21 forms a positive pole and each second grounding electrode 22 forms a negative pole. Each adjacent pole wire 21 and second grounding electrode 22 form a second sub-electric field, and all of the second sub-electric fields together form the second electric field. Thus, a second electric field superimposed on the first electric field is formed by the pole wires 21 and second grounding electrodes 22.

[0081] Furthermore, the second pole assembly 20 can be arranged above the first pole assembly 10 along the direction of gravity, and the pole wires 21 in the second pole assembly 20 and the second grounding electrodes 22 are spaced and staggered along the first direction a, and the repelling electrodes 12 in the first pole assembly 10 and the first grounding electrodes 13 are spaced and staggered along the first direction a.

[0082] As shown in Figure 6 , each first electric field is superimposed with a second electric field. When the target medium passes through the dust collection space 11, the combined electric field forces of the first and second electric fields increase the movement path of the charged particles within the dust collection space 11, allowing the charged particles to be smoothly collected on the first grounding electrode 13 within the dust collection space 11, reducing the probability of charged particles escaping and improving dust removal efficiency.

[0083] In some embodiments, the first pole assembly 10 and the second pole assembly 20 are detachably connected.

[0084] It should be noted that in the structure of the electric purification device 100, a tungsten wire is usually provided at the front end, and a repelling electrode 12 and a first grounding electrode 13 are provided at the rear end. As use progresses, a large amount of dust is adsorbed on the first grounding electrode 13, so the electric purification device 100 needs to be cleaned in a timely manner.

[0085] However, during cleaning, it is usually necessary to clean only the repelling electrode 12 and the first grounding electrode 13, that is, the structure of the first pole assembly 10. However, during the cleaning process of the first pole assembly 10, the tungsten wire may be easily touched, thereby causing the tungsten wire to break.

[0086] Therefore, by detachably connecting the first pole assembly 10 and the second pole assembly 20, the second pole assembly 20 can be removed during the cleaning process to facilitate separate cleaning of the first pole assembly 10, which can effectively reduce the risk of the pole wire 21 in the second pole assembly 20 breaking during the cleaning process.

[0087] Referring to FIG. 2 again, in some embodiments, one of the first pole assembly 10 and the second pole assembly 20 is provided with a clamping portion 14 , and the other is provided with a buckling portion 23 that is engaged with the clamping portion 14 .

[0088] Specifically, a clamping portion 14 may be provided on the first pole assembly 10 , and a buckling portion 23 may be provided on the second pole assembly 20 . The clamping portion 14 and the buckling portion 23 may be buckled together to achieve a detachable connection between the first pole assembly 10 and the second pole assembly 20 .

[0089] During disassembly, the second pole assembly 20 can be grasped and lifted upward to separate the second pole assembly 20 from the first pole assembly 10 so as to clean the first pole assembly 10 separately.

[0090] Of course, the buckling portion 23 may be provided on the first pole assembly 10 and the clamping portion 14 may be provided on the second pole assembly 20 , so as to achieve a buckling connection between the first pole assembly 10 and the second pole assembly 20 .

[0091] In some other embodiments, the first pole assembly 10 and the second pole assembly 20 may also be detachably connected by other connection methods, such as threaded connection, which will not be described in detail here.

[0092] Based on the same concept as the above-mentioned electric purification device 100, the present application provides an air purifier, including the above-mentioned electric purification device 100.

[0093] As shown in FIG7 , based on the same concept as the above-mentioned electric purification device 100 , the present application also provides an electric purification method, including the following steps:

[0094] S10 : applying a first electric field in the dust collecting space 11 .

[0095] S20: applying a second electric field in the dust collecting space 11 , the electric field force direction of which intersects with the electric field force direction of the first electric field.

[0096] S30: introducing a target medium into the dust collecting space 11, and making the moving direction of the target medium in the dust collecting space 11 intersect with the electric field force directions of the first electric field and the second electric field respectively.

[0097] Specifically, the target medium's movement direction within the dust collection space 11 is perpendicular to the electric field force directions of the first electric field and the second electric field. That is, the electric field force direction of the first electric field is perpendicular to the electric field force direction of the second electric field, and the electric field force directions of the first electric field and the second electric field are perpendicular to the target medium's movement direction within the dust collection space 11.

[0098] The first electric field charges the target particles in the target medium, turning them into charged particles. Within dust collection space 11, the charged particles are simultaneously subject to the electric force of the first electric field, the electric force of the second electric field, and the force of the airflow. These three forces act together to cause the charged particles to move in a diagonal path within dust collection space 11, moving toward first ground electrode 13. This allows the charged particles to be collected on first ground electrode 13 within dust collection space 11, achieving dust removal.

[0099] According to the electric purification device, air purifier and electric purification method of the present application, when the target medium passes through the dust collecting space, the target particles in the target medium are charged, and the target particles are respectively subjected to the electric field force of the first electric field and the electric field force of the second electric field in the dust collecting space, and the directions of the two electric field forces intersect with the movement directions of the target particles in the dust collecting space respectively; thus, under the combined action of the two intersecting electric field forces, the movement path of the target particles in the dust collecting space is increased, and a combined force is formed on the target particles approaching the first pole assembly, so that more charged target particles are collected, thereby improving the dust removal efficiency.

[0100] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0101] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
