Description

Technical Field

[0001] This application relates to the technical field of air purifiers, and more particularly, to a dust collection electrode collector structure and an air purifier. Background Art

[0002] With the increasing attention and requirements of people's lives for air quality, it has become the first choice for people to improve indoor air quality through air purifiers. Among air purifiers in the industry, an air purifier based on electrostatic dust collection technology has the following working principle:

[0003] Air purifiers based on electrostatic dust collection technology all include a discharge electrode and a collector electrode placed between the air inlet and the air outlet. The discharge electrode and the collector electrode are placed opposite to each other at a fixed distance. Under the action of high-voltage ionization, the discharge electrode forms a plasma field, ionizing air molecules and making them carry positive charges. The ionized air is accelerated under the action of the electric field force formed by the discharge electrode and the collector electrode to collide with other particles, making them carry positive charges. Through a series of snowball-like avalanche effects, dust and bacteria passing through the electric field are all charged and move towards the collector electrode, and are finally adsorbed by the collector electrode; the collector electrode module itself includes a collector plate and a repelling plate, which carry opposite charges. When dust is adsorbed, the collector plate with the opposite charge plays an adsorption role, and the repelling plate plays a repelling role, pushing the dust towards the direction of the collector plate.

[0004] With the accumulation of technical experience, air purifiers with increasingly mature electrostatic dust collection technology have been rapidly and widely accepted by the market due to their technical advantages such as being washable and reusable, killing bacteria with an electrostatic field, and being able to capture and purify smaller particles.

[0005] Existing air purifiers with electrostatic dust collection technology have the following disadvantages: 1. The assembly is complex and time-consuming; 2. The distance between the dust collection plates is very narrow after assembly, and it is difficult to thoroughly clean them with daily tools; 3. The assembly structure of the dust collection electrode seat has slits and narrow grooves, which are prone to accumulating dirt and moisture, and are prone to tip discharge and tracking. Summary of the Invention

[0006] The purpose of this application is to provide a dust collection electrode collector structure, which is simple to assemble, can achieve easy cleaning and drying of the collector plate, avoid tip discharge and tracking, and improve the user experience.

[0007] Another purpose of this application is to provide an air purifier.

[0008] According to the dust collection electrode collector structure of the first aspect embodiment of this application, it includes a frame body, a collector electrode insertion plate group, and a repelling electrode insertion plate group. The collector electrode insertion plate group and the repelling electrode insertion plate group are respectively detachably installed in the frame body;

[0009] The collector plate group includes an upper collector plate group and a lower collector plate group. The upper collector plate group and the lower collector plate group are detachably connected. The upper collector plate group includes a plurality of upper collector plates, and the lower collector plate group includes a plurality of lower collector plates. The upper collector plates and the lower collector plates are arranged alternately.

[0010] According to the collector electrode structure of the dust collecting electrode in the embodiments of the present application, the assembly is simple. The collector plate group can be taken out of the frame as a whole, realizing the separation of the collector plate and the repelling plate (primary separation). The plate spacing (the spacing between two plates) becomes twice the original. After the upper collector plate group and the lower collector plate group are separated, secondary separation is realized. After the secondary separation, the plate spacing (the spacing between two collector plates) becomes four times the original. After the upper collector plates and the lower collector plates are separated, the spacing between the upper collector plates and the spacing between the lower collector plates are sufficient for detailed and comprehensive cleaning with daily tools and are easy to dry, avoiding tip discharge and tracking, and improving the user experience.

[0011] In addition, the collector electrode structure of the dust collecting electrode in the embodiments of the present application also has the following additional technical features:

[0015] In the above embodiment, the upper collector plate group is sleeved on the lower collector plate group, and the upper collector plates and the lower collector plates are inserted in a staggered manner to ensure that the collector plates are arranged at equal intervals.

[0016] In some specific embodiments of the present application, a plurality of card slots are provided on both the third connecting plate and the fourth connecting plate. The two ends of the upper collector plate are respectively inserted into the card slots on the third connecting plate and the fourth connecting plate.

[0017] In the above embodiment, the two ends of the upper collector plate are inserted into the card slots on the third connecting plate and the fourth connecting plate, which is convenient for realizing the assembly of the upper collector plate group and the lower collector plate group and saves installation space.

[0021] In some specific embodiments of the present application, the materials of the upper collection electrode plate group and the lower collection electrode plate group are both carbon fiber reinforced resin.

[0022] In the above embodiment, for the collection electrode plate integrally formed with carbon fiber reinforced resin, due to the hydrophobicity of the base resin and the smoothness of the electrode plate surface, only a small amount of water droplets remain on the surface after cleaning and it is easy to dry.

[0023] In some specific embodiments of the present application, a graphene composite carbon nanotube conductive coating is sprayed on the surfaces of the first cylindrical protrusion and the second cylindrical protrusion.

[0024] In the above embodiment, the graphene composite carbon nanotube conductive coating solves the problem of uneven surface resistance caused by uneven mixing of carbon fiber and the base material, which affects the corona efficiency; the coating is dense and firm, resistant to friction, and solves the problem of easy detachment during cleaning.

[0027] According to some embodiments of the present application, the upper collection electrode plate group and the lower collection electrode plate group are locked by a cantilever hook engaging structure.

[0028] In the above embodiment, the locking of the upper collection electrode plate group and the lower collection electrode plate group is realized through the cantilever hook engaging structure, which facilitates the assembly and disassembly of the upper collection electrode plate group and the lower collection electrode plate group.

[0029] According to some embodiments of the present application, engaging bosses are fixed on the collecting electrode insertion plate group, and sliding push buttons corresponding to the engaging bosses are arranged on the frame body. The sliding push buttons are slidably matched with the frame body and can move relative to the frame body to cooperate with or separate from the engaging bosses, so as to lock or loosen the collecting electrode insertion plate group.

[0046] The dust collection electrode collector structure 100 according to the first aspect embodiment of the present application will be described below with reference to the drawings.

[0047] As Figure 1 shown, the dust collection electrode collector structure 100 according to the embodiment of the present application includes: a frame body 10, a collector plate group 20, and a repelling electrode plate group 30.

[0048] Specifically, as Figure 2 shown, the frame body 10 plays a role of positioning and supporting. The collector plate group 20 and the repelling electrode plate group 30 are respectively detachably installed in the frame body 10, and the collector plates 21 and the repelling electrode plates 31 are alternately arranged. As Figure 3 shown, the distance between the collector plates (the distance between the collector plates 21 and the repelling electrode plates 31) is D. As Figure 4 shown, the collector plate group 20 includes an upper collector plate group 22 and a lower collector plate group 23. The upper collector plate group 22 and the lower collector plate group 23 are detachably connected. The upper collector plate group 22 includes a plurality of upper collector plates 221, and the lower collector plate group 23 includes a plurality of lower collector plates 231. The upper collector plates 221 and the lower collector plates 231 are alternately arranged. The upper collector plates 221 and the lower collector plates 231 are collectively referred to as collector plates 21. The collector plates 21 and the repelling electrode plates 31 are alternately arranged to facilitate dust collection on the collector plates 21.

[0049] The dust collection electrode collector structure 100 according to the embodiment of the present application has simple assembly. The collector plate group 20 can be integrally taken out from the frame body 10 to separate the collector plates 21 and the repelling electrode plates 31 (primary separation), and the plate distance (the distance between two collector plates 21) becomes 2D (as Figure 1 shown). After the upper collector plate group 22 and the lower collector plate group 23 are separated, secondary separation is achieved. After secondary separation, the plate distance (the distance between two upper collector plates 221 or the distance between two lower collector plates 231) becomes 4D (as Figure 4 shown); after the upper collector plates 221 and the lower collector plates 231 are separated, the distances between the upper collector plates 221 and the lower collector plates 231 are sufficient to be cleaned in detail and comprehensively using daily tools, and are easy to dry, avoiding tip discharge and tracking, and improving the user experience.

[0050] The structural features and connection methods of the components of the dust collecting electrode collector structure 100 according to the embodiments of the first aspect of the present application will be described below with reference to the accompanying drawings.

[0051] As Figure 1 shown, the frame 10 is a rectangular frame for accommodating the collector plate group 20 and the repelling electrode plate group 30. The collector plate group 20 is located above the repelling electrode plate group 30.

[0052] The repelling electrode plate group 30 is detachably connected to the frame 10. As Figure 3 shown, the repelling electrode plate group 30 includes a plurality of repelling electrode plates 31 arranged side by side. The repelling electrode plates 31 and the collector plates 21 are arranged alternately. Since the repelling electrode plates 31 repel charged particles and do not play an adsorption role, the repelling electrode plates 31 do not need to be cleaned. At the same time, the specific structure of the repelling electrode plate group 30 will not be introduced in detail in this application.

[0053] The components of the collector plate group 20 will be mainly introduced below.

[0054] As Figure 4 shown, the upper collector plate group 22 of the collector electrode includes a plurality of upper collector plates 221, a first connecting plate 222 and a second connecting plate 223. The plurality of upper collector plates 221 are arranged side by side between the first connecting plate 222 and the second connecting plate 223. Both ends of each upper collector plate 221 are respectively connected to the first connecting plate 222 and the second connecting plate 223. The first connecting plate 222, the plurality of upper collector plates 221 and the second connecting plate 223 are integrally formed, avoiding the insertion and assembly of the plurality of upper collector plates 221 and saving assembly time.

[0055] As Figure 4 shown, the lower collector plate group 23 of the collector electrode includes a plurality of lower collector plates 231, a third connecting plate 232 and a fourth connecting plate 233. The plurality of lower collector plates 231 are arranged side by side between the third connecting plate 232 and the fourth connecting plate 233. Both ends of each lower collector plate 231 are respectively connected to the third connecting plate 232 and the fourth connecting plate 233. The third connecting plate 232, the plurality of lower collector plates 231 and the fourth connecting plate 233 are integrally formed, avoiding the insertion and assembly of the plurality of lower collector plates 231 and saving assembly time.

[0056] In order to facilitate the insertion of the collector plate group 20 and the repelling electrode plate group 30, both the upper collector plate 221 and the lower collector plate 231 are of T-shaped structures.

[0057] When the upper collector plate group 22 and the lower collector plate group 23 are assembled, the first connecting plate 222 corresponds to the third connecting plate 232, and the second connecting plate 223 corresponds to the fourth connecting plate 233. The first connecting plate 222 and the second connecting plate 223 are sleeved outside the third connecting plate 232 and the fourth connecting plate 233. In order to save installation space and ensure that the upper and lower ends of the upper collector plate 221 and the lower collector plate 231 are flush, a plurality of card slots 234 are formed in both the third connecting plate 232 and the fourth connecting plate 233. The plurality of card slots 234 are spaced along the length direction of the third connecting plate 232 or the fourth connecting plate 233. The two ends of the upper collector plate 221 are respectively inserted into the card slots 234 on the third connecting plate 232 and the fourth connecting plate 233. As an alternative embodiment of the present application, the card slot 234 has a V-shaped structure, which is convenient for the upper collector plate 221 to be inserted into the card slot 234.

[0058] It should be noted that, as Figure 1 shown, the upper collector plates 221 at both ends of the upper collector plate group 22 are not inserted into the card slots 234 because there are no corresponding card slots 234 at the ends of these two upper collector plates 221.

[0059] Furthermore, as Figure 3 and Figure 4 shown, a first cylindrical protrusion 224 is formed on the upper side (the side away from the repelling plate group 30) of the upper collector plate 221. The two ends of the first cylindrical protrusion 224 are respectively connected to the first connecting plate 222 and the second connecting plate 223. A second cylindrical protrusion 235 is formed on the upper side (the side away from the repelling plate group 30) of the lower collector plate 231. The two ends of the second cylindrical protrusion 235 are respectively connected to the third connecting plate 232 and the fourth connecting plate 233. The design of the first cylindrical protrusion 224 and the second cylindrical protrusion 235 increases the sectional moment of inertia of the collector plate 21 (collectively referred to as the upper collector plate 221 and the lower collector plate 231), enhances the rigidity of the collector plate 21, is not easily bent and deformed during cleaning, and keeps the spacing of the overall collector plate 21 uniform, providing a guarantee for providing a uniform electric field.

[0060] Furthermore, the first connecting plate 222, the plurality of upper collector plates 221, and the second connecting plate 223 are integrally formed by carbon fiber reinforced resin. The third connecting plate 232, the plurality of lower collector plates 231, and the fourth connecting plate 233 are integrally formed by carbon fiber reinforced resin. By adjusting the ratio of carbon fiber to base resin, the resistivity of the material itself is controlled within 10 4Within Ω / CM, when the integral collecting plate 21 is connected to high voltage electricity, it is in a conducting state, providing a uniform and consistent electric field. The collecting plate 21 is integrally formed with carbon fiber reinforced resin and is designed with an open side-by-side array structure. There are no positions such as cracks and narrow grooves in the structure itself that are difficult to clean, and it is easy to clean thoroughly, avoiding the occurrence of poor phenomena such as creepage and discharge of dirty media.

[0061] The collecting plate 21 integrally formed with carbon fiber reinforced resin is very easy to clean during cleaning due to the hydrophobicity of the base resin and the smoothness of the plate surface. After cleaning, only a small amount of water droplets remain on the surface. At room temperature of 25°C, it can be dried in 10 - 30 minutes, or it can be directly wiped dry with a dry towel and then used.

[0062] Furthermore, the surfaces of the first cylindrical protrusion 224 and the second cylindrical protrusion 235 are both sprayed with a graphene composite carbon nanotube conductive coating, and the thickness of the coating is 0.3μm, controlling the surface resistance value of the entire cylinder within 800Ω / cm, solving the problem of uneven surface resistance caused by uneven mixing of carbon fiber and the base material, which affects the corona efficiency. The graphene coating is fused with the base material of the collecting plate 21 through a special formula, and the coating is dense and firm, resistant to friction, solving the problem of easy shedding during cleaning.

[0063] Furthermore, the upper plug-in plate group 22 of the collecting electrode and the lower plug-in plate group 23 of the collecting electrode are locked through a cantilever hook engaging structure. As Figure 5 shown, cantilever hooks 225 are provided inside the first connecting plate 222 and the second connecting plate 223, and buckles 236 are provided on the third connecting plate 232 and the fourth connecting plate 233. When the upper plug-in plate group 22 of the collecting electrode and the lower plug-in plate group 23 of the collecting electrode are assembled, the upper plug-in plate group 22 of the collecting electrode is sleeved on the lower plug-in plate group 23 of the collecting electrode. The first connecting plate 222 corresponds to the third connecting plate 232, and the second connecting plate 223 corresponds to the fourth connecting plate 233. The cantilever hooks 225 are engaged with the buckles 236 to lock the upper plug-in plate group 22 of the collecting electrode and the lower plug-in plate group 23 of the collecting electrode. When it is necessary to separate the upper plug-in plate group 22 of the collecting electrode, press the lower plug-in plate group 23 of the collecting electrode, and the cantilever hook engaging structure can be opened to separate the upper plug-in plate group 22 of the collecting electrode and the lower plug-in plate group 23 of the collecting electrode.

[0064] According to some embodiments of the present application, as Figure 5As shown, engaging bosses 226 are fixed on the first connecting plate 222 and the second connecting plate 223 (the engaging bosses 226 are U-shaped structures with the openings facing the outside of the first connecting plate 222). A sliding push button 11 corresponding to the engaging bosses 226 is provided on the frame 10. The sliding push button 11 is slidably engaged with the frame 10 and can move relative to the frame 10. The sliding push button 11 has a locking position and an unlocking position. A return spring (not marked in the figure) is also provided on the frame 10 to move the sliding push button 11 towards the locking position. When the sliding push button 11 is in the locking position, the tongue of the sliding push button 11 cooperates with the engaging boss 226 (the tongue of the sliding push button 11 is inserted into the opening of the engaging boss 226), locking the collector plate group 20 to the frame 10. When the sliding push button 11 is in the unlocking position, the tongue of the sliding push button 11 is separated from the engaging boss 226, so that the collector plate group 20 is separated from the frame 10, and the collector plate group 20 can be pulled out from the frame 10.

[0065] Further, an unlocking indication mark 12 is provided on the frame 10, and the user can push the sliding push button 11 according to the unlocking indication mark 12 to perform the unlocking operation. The unlocking indication mark 12 is an unlocking symbol and corresponds to the unlocking position of the sliding push button 11. When the user pushes the sliding push button 11 towards the unlocking indication mark 12, the tongue of the sliding push button 11 can be separated from the engaging boss 226, so that the collector plate group 20 can be pulled out from the frame 10.

[0066] Further, for the convenience of extracting the collector plate group 20, as Figure 1 and Figure 4 shown, lifting handles 227 are provided on both the first connecting plate 222 and the second connecting plate 223.

[0067] Power connection method: A collector potential contact piece 13 and a repeller potential contact piece 14 are provided on the frame 10. The collector electric field voltage is connected to the collector plate 21 through the collector potential contact piece 13 and the collector potential adapter piece 15 (since the collector plate group 20 needs to be taken out for cleaning, the collector potential adapter piece 15 is added to connect the collector potential contact piece 13 to the collector plate group 20), and the repeller electric field voltage is connected to the repeller plate 31 through the repeller potential contact piece 14.

[0068] The disassembly method of the dust collecting electrode collector structure 100 according to the embodiment of the present application is:

[0069] Push the sliding push button 11 towards the unlocking indication mark 12. The tongue of the sliding push button 11 is separated from the engaging boss 226. Lift the collecting electrode plate group 20 out of the housing 10 through the handle 227 at both ends of the collecting electrode plate group 20 to achieve primary separation. After the primary separation, the distance between the collecting electrode plates 21 becomes 2D. After the collecting electrode plate group 20 is taken out, press the lower inserting plate group 23 of the collecting electrode by hand, and the cantilever hook engaging structure is opened, and the upper inserting plate group 22 of the collecting electrode is separated from the lower inserting plate group 23 of the collecting electrode to achieve secondary separation. After the secondary separation, the distance between the collecting electrode plates 21 (the distance between the upper collecting inserting plate 221 and the lower collecting inserting plate 231) becomes 4D.

[0070] The collecting electrode structure 100 of the dust collecting electrode according to the embodiment of the present application can separate the upper collecting inserting plate 221 and the lower collecting inserting plate 231, so as to facilitate the cleaning of the collecting electrode plates 21. At the same time, the collecting electrode plates 21 are made of carbon fiber reinforced resin. After cleaning, only a small amount of water droplets remain on the surface, which is easy to dry, facilitating the cleaning of the collecting electrode plates 21.

[0071] An embodiment of the second aspect of the present application provides an air purifier, which includes the collecting electrode structure 100 according to the embodiment of the first aspect of the present application.

[0072] When the air purifier needs to be cleaned, take out the collecting electrode plate group 20 from the housing 10, separate the upper collecting inserting plate 221 and the lower collecting inserting plate 231, which facilitates the cleaning of the collecting electrode plates 21 and has high cleaning efficiency.

[0073] It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other.

[0074] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
