Description

Technical Field

[0001] This invention relates to the field of air purification technology, specifically to a power supply mechanism, a dust collection module, and an air purifier. Background Technology

[0002] High-voltage electrostatic dust collection technology is a mature air purification technology. Its core structure includes a high-voltage power supply, a corona discharge device (generating electrode), and a dust collection device (collecting electrode). The basic working principles of the high-voltage power supply module, electrostatic dust collection, and corona discharge device are common knowledge in the field and will not be elaborated here.

[0003] In the field of traditional high-voltage electrostatic precipitator technology, the power supply connection structure of electrode modules has formed a relatively fixed technical solution. Specifically, the traditional collecting electrode module adopts a metal spring contact power supply, with the metal springs arranged on the left, right, and rear sides of the collecting electrode; the traditional generating electrode adopts a metal spring or pin power supply, with the metal springs or pins also arranged on the left, right, and rear sides of the generating electrode. The core reason why the above power supply scheme can be widely used and is technically mature is that the traditional collecting and generating electrodes are designed as cuboid structures. This structure is formed by arranging metal electrode plates at preset intervals. When the cuboid electrode module is horizontally inserted into the equipment compartment, its regular shape can form a natural positioning structure. It is only necessary to pre-embed wires at the corresponding insertion path positions on the compartment shell and expose the contact springs to achieve the power supply connection with the electrostatic module.

[0004] However, with the development of electrostatic dust collection technology and the diversification of product forms, the limitations of traditional power supply structures have gradually become apparent, especially in scenarios where the electrode module adopts a non-cubic structure, where the defects are more significant. For example, in scenarios where the collecting electrode is designed as a circular structure (such as the roll-wound circular collecting electrode disclosed in patent CN118768088A), if the traditional solution of arranging metal springs or pins in the circumference of the collecting electrode is used, the lack of an effective positioning structure will lead to insufficient assembly accuracy when the disc-shaped electrostatic module is inserted into the engine compartment; if a straight edge is added to the disc-shaped module or part of the edge is cut off to form a positioning structure, it will damage the appearance integrity of the product and does not conform to the aesthetic logic of industrial design.

[0005] Meanwhile, traditional power supply structures also present significant electrical safety hazards: the positive and negative poles draw power from the same location on the side of the module, which can easily lead to an excessively short safety distance between the poles, potentially causing creepage under high-voltage conditions. Furthermore, when the equipment body adopts a cylindrical design, the traditional horizontal insertion method for assembling electrode modules has obvious defects. To remove the electrostatic module from the cylindrical housing, the body must be cut along its maximum diameter. This design not only significantly weakens the axial load-bearing stability of the main body and limits the aesthetic possibilities of industrial design, but also increases the difficulty of operation for users and reduces the ease of use of the product.

[0006] More importantly, traditional power supply structures lack targeted protection designs. In humid and dusty environments, high-voltage electrodes are prone to leakage current traces due to flashover, which can form conductive paths and ultimately cause short circuit failure of the high-voltage electrostatic dust collection system. This can lead to partial discharge burning and abnormal discharge noises, seriously affecting the product's lifespan and safety.

[0007] Therefore, there is an urgent need for a new type of connection and power supply structure that can adapt to the assembly requirements of non-cubic electrode modules, while solving the problems of low positioning accuracy, large electrical safety hazards, and poor product form adaptability of traditional structures, so as to achieve stable power supply from high voltage power supply to corona device and dust collection device. Summary of the Invention

[0008] Therefore, the technical problem to be solved by the present invention is to overcome the problem that non-cubic electrode modules in the prior art are difficult to stably supply power, and to provide a power supply mechanism, a dust collection module and an air purifier.

[0009] To solve the above-mentioned technical problems, the present invention provides a power supply mechanism, including a base, a high-voltage power supply, and a power supply handle, a power supply pen, and a docking assembly respectively connected to the high-voltage power supply. The high-voltage power supply is placed inside the base, the power supply handle protrudes from the top surface of the base, and the docking assembly is disposed on the top surface of the base and surrounds the power supply handle.

[0010] In one embodiment of the present invention, the power supply handle includes a handle body and a climbing rod. The handle body is connected to the base and extends vertically.

[0011] In one embodiment of the present invention, the housing is provided with an assembly groove and a positioning groove inside. The assembly groove is recessed downward from the top surface of the housing. The grounding conductive post is disposed in the assembly groove. The positioning groove and the assembly groove are respectively disposed on both sides of the housing.

[0012] In one embodiment of the present invention, the outer surface of the housing and the outer surface of the power supply handle are both configured as non-cylindrical structures.

[0013] In one embodiment of the present invention, the power supply terminal of the power supply pen is provided with a generating electrode female, the diameter of which gradually narrows in the direction toward the generating electrode.

[0014] In one embodiment of the present invention, the base includes a base and a tower support, the sidewalls of the tower support are configured to gradually and smoothly taper inward in a direction away from the base; the power supply handle protrudes from the top surface of the tower support, the docking assembly is disposed on the top surface of the tower support; and the power supply pen is connected to the base.

[0015] The present invention also provides a dust collection module, comprising: the aforementioned power supply mechanism; a corona assembly, the corona assembly comprising a corona frame and generating electrodes and a grounding tongue respectively disposed on the corona frame, wherein the corona frame is sleeved on the housing and supported on the base, the generating electrodes are connected to the power supply terminal of the power supply pen, and the grounding tongue is connected to the grounding conductive post; and a dust collection assembly, the dust collection assembly comprising a dust collection frame and dust collection electrodes disposed on the dust collection frame, the dust collection frame being sleeved on the power supply handle and supported on the corona assembly, and the first connector being connected to the dust collection electrodes.

[0016] In one embodiment of the present invention, the grounding tongue is provided with a pressing post, the pressing post protruding toward the dust collection assembly, so as to press the grounding tongue into the assembly groove of the housing by the dust collection assembly and connect it with the grounding conductive post; the corona assembly further includes a positioning tongue, the positioning tongue being able to be embedded in the positioning groove of the housing.

[0017] In one embodiment of the present invention, the corona frame includes a grounding plate, the grounding plate and the generating electrode are spaced apart in the thickness direction of the corona frame, the grounding tongue is disposed on the grounding plate, and the center of the grounding plate is provided with a first mounting hole that matches the shape of the outer surface of the housing.

[0018] In one embodiment of the present invention, the dust collection frame is provided with a second mounting hole at its center that matches the shape of the outer surface of the power supply handle; the generating electrode is provided with a second connector, which is inserted into the generating electrode female seat.

[0019] In one embodiment of the present invention, the dust collection assembly further includes an adapter assembly and a roll film, the roll film being connected to the dust collection frame and having one end connected to the dust collection electrode, and the adapter assembly being disposed between the dust collection electrode and the roll film to enable the dust collection electrode to be electrically connected to the roll film.

[0020] In one embodiment of the present invention, the adapter assembly includes a fixing member and an adapter piece. The adapter piece includes a connecting portion and two pressing portions. The dust collection electrode is connected to the connecting portion through the fixing member. The two pressing portions are disposed on the side of the connecting portion facing the roll film and are disposed on both sides of the connecting portion. Both pressing portions abut against the roll film.

[0021] In one embodiment of the present invention, the dust collection frame is provided with a collecting electrode female seat, the dust collection electrode is disposed in the collecting electrode female seat, and the first connector can be inserted into the collecting electrode female seat and electrically connected to the dust collection electrode.

[0022] The present invention also provides an air purifier, which includes the above-mentioned dust collection module, main unit and coupler. The male coupling of the coupler is disposed on the main unit, and the female coupling of the coupler is disposed on the power supply end of the power supply handle in the dust collection module. The male coupling can be plugged into the female coupling to connect the dust collection module and the main unit.

[0023] The technical solution of the present invention has the following advantages over the prior art: The power-feeding mechanism of this invention integrates a high-voltage power supply, a power-feeding handle, a power-feeding pen, and a docking assembly into a single unit. Its compact structure and rational layout allow for simultaneous power supply to both the power-feeding pen and the docking assembly via the high-voltage power supply. One device can meet the power requirements of both the external corona structure and the dust collection structure, eliminating the need for multiple additional power supply systems. This significantly simplifies the wiring and installation process of external equipment, reducing overall equipment setup costs and space occupancy. The power-feeding pen and the docking assembly output voltages with opposite polarities, enabling the corona structure to generate a strong electric field that charges dust particles. Simultaneously, the dust collection structure forms a reverse high-voltage dust collection electric field. Under the influence of the electric field, the charged dust particles rapidly move towards the dust collection structure and are adsorbed. It effectively improves dust capture efficiency and optimizes electrostatic precipitator performance; the grounding conductive post on the docking component housing can promptly conduct stray currents and static electricity generated during equipment operation to the ground, avoiding equipment short circuits, electrostatic breakdowns, and other faults caused by charge accumulation, eliminating the risk of electric shock in high-voltage working environments, and improving the safety and stability of the entire system operation; the docking component is set around the power-receiving handle, and its housing can protect the power-receiving handle, reducing the corrosion of the power-receiving handle by external dust and moisture, while fixing the relative position of the power-receiving handle and the docking component, realizing quick positioning and docking with external equipment, reducing installation difficulty, and facilitating subsequent equipment inspection and component replacement, thus improving maintenance convenience.

[0024] Based on this, the dust collection module and air purifier innovatively propose a tower-style vertical stacked structure consisting of a base, docking components, corona components, and dust collection components. This eliminates the limitations of traditional horizontal insertion structures. The corona frame is directly fitted onto the docking component housing, and the dust collection frame is fitted onto the power-on handle and supported on the corona component. Precise alignment of each component can be achieved without additional positioning straight edges or guide grooves. This not only breaks through the limitations of traditional cuboid modules on equipment cabin shapes, allowing it to adapt to diverse product designs such as round and cylindrical shapes, but also significantly simplifies the assembly process. Users can quickly complete the installation simply by stacking the components using their own weight, significantly reducing assembly difficulty and operational barriers. Simultaneously, it effectively prevents flashover of high-voltage electricity caused by moisture and dirt, avoiding the formation of conductive paths due to leakage current traces, which could lead to short circuits and failures in the high-voltage electrostatic dust collection system.

[0025] Furthermore, this application utilizes the downward pressure of gravity on the dust collection component to ensure a tight fit between the grounding tongue of the corona component and the grounding conductive post of the docking component, guaranteeing reliable conductivity between the first connector and the dust collection electrode. This replaces the shortcomings of traditional side spring connections, which are susceptible to assembly tolerances and long-term wear. During equipment operation, the connection status of each component will not loosen due to vibration, deformation, or other factors, and a stable high-voltage electrostatic field can be maintained at all times. This ensures that the corona ionization and particulate matter capture effects are stable and long-lasting, effectively improving the operational reliability and service life of the dust collection module.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0030] Example 1: See Figures 1 to 3As shown, this embodiment provides a power-giving mechanism, which includes a base 100 and a power-giving mechanism 200. The power-giving mechanism 200 includes a high-voltage power supply 240 and a power-giving handle 210, a power-giving pen 220, and a docking assembly 230 respectively connected to the high-voltage power supply 240. The high-voltage power supply 240 is disposed inside the base 100. One end of the power-giving handle 210 is connected to the high-voltage power supply 240, and the other end protrudes from the top surface of the base 100. The docking assembly 230 is disposed on the top surface of the base 100 and surrounds the power-giving handle 210. The docking assembly 230 includes a housing 231 and grounding conductive posts 232 and a first connector group respectively disposed on the housing 231. The power-giving pen 220 is connected to the base 100 through the housing, and the voltage polarity output by the power-giving pen 220 is opposite to that of the first connector group.

[0031] This device integrates a high-voltage power supply, a charging handle, a charging pen, and a docking assembly into a single unit. Its compact structure and rational layout allow for simultaneous power supply to both the charging pen and the docking assembly via the high-voltage power supply. One unit can meet the power requirements of both the external corona structure and the dust collection structure, eliminating the need for multiple additional power supply systems. This significantly simplifies the wiring and installation process of external equipment, reducing overall equipment setup costs and space occupancy. The charging pen and docking assembly output voltages with opposite polarities, generating a strong electric field in the corona structure that charges dust particles. Simultaneously, the dust collection structure forms a reverse high-voltage electric field. Under the influence of this electric field, the charged dust particles rapidly move towards the dust collection structure and are adsorbed, effectively improving dust collection efficiency. The improved dust capture efficiency optimizes the electrostatic precipitator effect. The grounding conductive posts on the docking component housing promptly conduct stray currents and static electricity generated during equipment operation to the ground, preventing short circuits and electrostatic breakdowns caused by charge accumulation. This eliminates the risk of electric shock in high-voltage operating environments and enhances the safety and stability of the entire system. The docking component, positioned around the power-receiving handle, protects the handle from external dust and moisture, reducing corrosion. It also fixes the relative position of the handle and the docking component, enabling rapid positioning and docking with external equipment, reducing installation difficulty, facilitating subsequent equipment maintenance and component replacement, and improving maintenance convenience.

[0032] The base 100 is the fundamental supporting component of the dust collection module of this application. It has an internal space for fixing the high-voltage power supply 240, preventing displacement or vibration during operation and ensuring power supply stability. Simultaneously, the base 100 provides a passageway for the power supply handle 210 and the power supply pen 220, and provides a stable assembly support surface for the docking component 230, the corona component 300, and the dust collection component 400. Precise structural design ensures the relative positional accuracy of each component, distributes the weight load of each component, and improves the structural reliability and assembly consistency of the entire dust collection module. In different embodiments, the overall shape of the base 100 can be adaptively adjusted according to actual usage requirements; this invention does not impose specific limitations in this regard.

[0033] Furthermore, the base includes a base and a tower support, the tower support being connected to the base, and the sidewalls of the tower support being configured to gradually and smoothly taper inwards in a direction away from the base. This smoothly tapering sidewall can precisely guide the airflow through the dust collection module, causing the airflow to converge smoothly towards the center of the module along the sidewall. This effectively prevents the formation of eddies in the gaps between the base and the components, ensuring that charged dust particles can pass uniformly and stably through the electric field regions of the corona discharge assembly and the dust collection assembly, thereby significantly improving the uniformity of dust collection and overall dust collection efficiency. Simultaneously, the tower-like taper structure gradually widens from top to bottom, perfectly conforming to the principles of mechanical load-bearing, and can evenly distribute the weight load of the corona discharge assembly and the dust collection assembly to the base, significantly reducing local stress on the sidewalls of the support and avoiding structural deformation or breakage due to long-term load-bearing, thus greatly improving the structural reliability and service life of the entire dust collection module. More importantly, the inwardly tapering sidewall design eliminates the creepage hazards such as sharp corners and steps that are easily formed in traditional equal-diameter structures. At the same time, it indirectly extends the creepage path between components with different potentials on the base surface. Combined with the smooth surface of the sidewall without grooves or dead corners, it can effectively prevent the adhesion and accumulation of dust and moisture, cut off the creepage channel at the structural level, significantly reduce the creepage risk in high-voltage electrostatic environments, and ensure the long-term stable operation of the module.

[0034] In this embodiment, the high-voltage power supply 240 serves as the energy source, outputting stable high-voltage direct current to provide the necessary electric field energy for corona discharge and dust adsorption. One end of the power supply handle 210 is connected to the high-voltage power supply 240, and the other end protrudes from the top of the base 100, which not only realizes the stable conduction of high-voltage electricity to the dust collection assembly 400, but also serves as the assembly support structure for the dust collection frame 410, realizing the positioning and installation of the dust collection assembly 400. The power supply pen 220 is connected to the base 100 and connected to a high-voltage power supply with the opposite polarity to the output of the docking component 230. This power supply provides electrical energy to the generating electrode 320 of the corona component 300, ensuring the smooth occurrence of corona discharge. The docking component 230 is located on the top surface of the base 100 around the power supply handle 210. Its housing 231 provides an installation carrier for the grounding conductive post 232 and the first connector 233 and achieves insulation isolation between the two to avoid short circuit faults. The grounding conductive post 232 is used to connect with the grounding tongue 330 of the corona component 300 to provide a potential reference point for corona discharge. The first connector 233 realizes the electrical connection between the high-voltage power supply 240 and the dust collection electrode 420, conducting the high-voltage power to the dust collection electrode 420. Finally, through the cooperation of various components, high-voltage power with opposite polarity is provided to the corona component 300 and the dust collection component 400, constructing the electric field foundation required for electrostatic dust collection.

[0035] Specifically, see Figure 3 and Figure 4 As shown, in this embodiment, the power-feeding handle 210 protrudes from the top surface of the tower support. The docking assembly 230 is disposed on the top surface of the tower support and includes a handle body 211 and a climbing rod 212. The handle body 211 is connected to the base 100 and extends vertically. The climbing rod 212 is disposed inside the handle body 211 and has multiple wire grooves. Multiple power lines 250 are correspondingly disposed in the multiple wire grooves. The multiple power lines 250 are all connected to the high-voltage power supply 240 and supply power to the power-feeding pen 220, the power-feeding handle 210, and the first connector 233, respectively. The handle 211 is connected to the base 100 and extends vertically, serving as both an assembly support structure for the dust collection frame 410, providing a stable installation and positioning reference for the dust collection assembly 400, and providing protection and housing space for the internal climbing rod 212. The climbing rod 212 is located inside the handle 211 and has multiple wire grooves. Multiple power lines 250 are correspondingly embedded in each wire groove. Through the separation and constraint effect of the wire grooves, the power lines 250 can be effectively prevented from tangling, abrasion, or short circuit, ensuring power supply safety. The multiple power lines 250 are electrically connected to the high-voltage power supply 240 and supply power to the power pen 220, the power handle 210 itself, and the first connector 233, respectively, realizing a stable multi-path distribution of high-voltage power and providing reliable power support for the corona discharge of the corona assembly 300 and the dust collection of the dust collection assembly 400.

[0036] Furthermore, the outer surfaces of the power-feeding handle 210 and the outer surfaces of the housing 231 are both configured as non-cylindrical structures. In this embodiment, a "D"-shaped structure is preferred. Compared to the traditional cylindrical structure, the non-cylindrical structure, on the one hand, restricts the circumferential relative rotation between the dust collection frame 410 and the power-feeding handle 210, and restricts the relative movement between the corona component 300 and the housing 231 during the assembly of the dust collection frame 410 and the corona frame 310, thus ensuring the relative positional accuracy between the conductive structures and avoiding uneven electric field distribution caused by component rotation, thereby ensuring the stability of the dust collection effect. On the other hand, the non-cylindrical structure can increase the contact area between the power-feeding handle 210 and the dust collection frame 410, improve the fit of the assembled structure, enhance the support stability of the dust collection component 400, prevent the dust collection frame 410 from loosening or shifting during operation, and further ensure the operational reliability of the entire dust collection module.

[0037] In different implementations, the docking component and the power-generating handle can be configured as an integrated structure for ease of manufacturing, or as a separate structure to improve their assembly and disassembly flexibility.

[0038] Furthermore, in this embodiment, the power supply end of the power supply pen 220 is provided with a generating electrode female socket 221. The diameter of the generating electrode female socket 221 gradually tapers towards the generating electrode 320. The generating electrode 320 is provided with a second connector 321, which is inserted into the generating electrode female socket 221. On the one hand, the tapered tapering diameter design can provide precise guidance for the insertion action of the second connector 321, reducing the alignment difficulty during assembly and improving the assembly efficiency of the corona component 300 and the power supply mechanism 200. On the other hand, the tapered structure allows the second connector 321 to fit tightly against the inner wall of the generating electrode female socket 221, increasing the contact area and reducing the contact resistance, thereby achieving stable conduction of high voltage and ensuring the stability of the energy supply for corona discharge of the generating electrode 320. At the same time, the tight insertion fit can also effectively prevent the second connector 321 from loosening or falling off during module operation, further improving the working reliability of the entire dust collection module.

[0039] More importantly, the voltage outputs of the power supply pen 220 and the docking component 230 have opposite polarities, forming a strong electric field distribution with opposing polarities between them. This creates a "canyon effect" similar to insulation and isolation, which greatly extends the creepage path between the two components to almost infinity. This fundamentally cuts off the discharge creepage channel caused by the high voltage difference, completely avoids the creepage damage fault that is most likely to occur in the operation of the high voltage electrostatic dust collector, and significantly improves the operational safety and service life of the dust collection module.

[0040] Example 2: This example provides a dust collection module, comprising: a power supply mechanism 200 as described in the example, a corona assembly 300, wherein the corona assembly 300 includes a corona frame 310 and a generating electrode 320 and a grounding tongue 330 respectively disposed on the corona frame 310, wherein the corona frame 310 is sleeved on the housing 231 and supported on the base 100, the generating electrode 320 is connected to the power supply terminal of the power supply pen 220, and the grounding tongue 330 is connected to the grounding conductive post 232; and a dust collection assembly 400, wherein the dust collection assembly 400 includes a dust collection frame 410 and a dust collection electrode 420 disposed on the dust collection frame 410, the dust collection frame 410 is sleeved on the power supply handle 210 and supported on the corona assembly 300, and the first connector 233 is connected to the dust collection electrode 420.

[0041] See Figure 5 and Figure 6 As shown, the corona assembly 300 is a structure for achieving dust ionization. Its corona frame 310 is sleeved on the housing 231 and supported on the base 100, serving as the mounting carrier for the generating electrode 320 and the grounding tongue 330. The frame structure ensures the relative positional accuracy of the two components and enables rapid assembly and positioning with the docking assembly 230, improving module assembly efficiency. The generating electrode 320 is connected to the power supply terminal of the power supply pen 220. After high voltage is applied, a strong electric field region is formed around it, causing air molecules to ionize and generate a large number of electrons and ions. These electrons and ions attach to the surface of the flowing dust particles, making the dust particles charged. The grounding tongue 330 is connected to the grounding conductive post 232 to achieve grounding, which not only provides a stable potential reference for the corona discharge of the generating electrode 320, ensuring the normal occurrence of corona discharge, but also helps to fix the assembly position of the corona frame 310, preventing the corona frame 310 from shifting during operation and ensuring the stability of the ionization effect.

[0042] Furthermore, in this embodiment, the housing 231 is provided with an assembly groove 2311 inside. The assembly groove 2311 is recessed downward from the top surface of the housing 231. The grounding conductive post 232 is disposed in the assembly groove 2311 to form a recessed assembly structure. The recessed assembly structure can form a creepage safety distance in the height direction and limit the grounding conductive post 232 to prevent displacement of the grounding conductive post 232 due to external collision or component assembly. At the same time, it can reduce the overall volume of the docking assembly 230 and optimize the spatial layout of the top surface of the base 100. The grounding tongue 330 can be embedded in the assembly groove 2311 and tightly connected to the grounding conductive post 232 in the assembly groove 2311. This achieves stable conduction between the grounding tongue 330 and the grounding conductive post 232, which simplifies the assembly process and ensures the reliability of the grounding of the corona assembly 300, providing a stable potential reference for corona discharge.

[0043] Furthermore, in this embodiment, the housing 231 is also provided with a surrounding plate 2313. The surrounding plate 2313 and the assembly groove 2311 on the housing 231 together form a limiting and protective space for accommodating and limiting the grounding tongue 330 and the grounding conductive post 232. On the one hand, the surrounding plate 2313 can protect the connection area between the grounding conductive post 232 and the grounding tongue 330 in the assembly groove 2311, preventing external dust and debris from entering the connection gap and affecting the grounding conductivity. On the other hand, the surrounding plate 2313 can effectively block external moisture from seeping into the enclosed space, preventing the grounding conductive post 232 and the grounding tongue 330 from short-circuiting or becoming poorly connected due to water accumulation. This ensures that the grounding structure can quickly return to a stable working state after cleaning and maintenance, improving the maintenance convenience and operational safety of the dust collection module.

[0044] In this embodiment, the housing 231 is further provided with a positioning groove 2312. The positioning groove 2312 and the assembly groove 2311 are respectively disposed on both sides of the housing 231. The corona assembly 300 also includes a positioning tongue 340, which can be embedded in the positioning groove 2312. During the assembly process of the corona frame 310 being fitted onto the housing 231, the positioning tongue 340 can be precisely embedded in the positioning groove 2312. Through the fitting and limiting effect of the positioning groove 2312 and the positioning tongue 340, the circumferential rotation and horizontal offset of the corona assembly 300 relative to the docking assembly 230 can be strictly limited, ensuring the alignment accuracy of the generating electrode 320 and the power supply terminal of the power supply pen 220, and the grounding tongue 330 and the grounding conductive post 232 on the corona assembly 300, avoiding problems such as poor power supply connection or grounding failure caused by assembly deviation. Meanwhile, the positioning slots 2312 and assembly slots 2311 on both sides form a dual positioning constraint, which further improves the assembly stability of the corona component 300, provides a precise structural foundation for the subsequent stacking and installation of the dust collection component 400, and ensures the uniformity of the electric field distribution and the reliability of the entire dust collection module.

[0045] Specifically, in this embodiment, the corona frame 310 includes a grounding plate 311. The grounding plate 311 and the generating electrode 320 are spaced apart in the thickness direction of the corona frame 310. The grounding tongue 330 is disposed on the grounding plate 311. The center of the grounding plate 311 is provided with a first mounting hole 312 that matches the shape of the outer surface of the housing 231.

[0046] The spacing between the grounding plate 311 and the generating electrode 320 avoids electrical connection between them, preventing short circuits. It also provides sufficient space for corona discharge from the generating electrode 320, ensuring the electric field strength in the ionization region is not affected by structural obstruction. The grounding tongue 330 is mounted on the grounding plate 311 and fixedly installed using the structural support of the plate, ensuring uniform force distribution during pressing and maintaining a stable connection with the grounding conductive post 232. The grounding plate 311 has a first mounting hole 312 at its center. The shape of the first mounting hole 312 matches the outer surface shape of the housing 231. During the assembly of the corona frame 310 onto the housing 231, this matching shape design ensures precise alignment between the corona frame 310 and the housing 231, limiting relative displacement and further improving the assembly accuracy of the corona assembly 300. This provides a stable structural foundation for the subsequent stacking and installation of the dust collection assembly 400.

[0047] In this embodiment, the grounding tongue 330 is provided with a pressing post 331. The pressing post 331 protrudes towards the dust collection assembly 400 so that the dust collection assembly 400 presses the grounding tongue 330 into the assembly groove 2311 and connects it with the grounding conductive post 232. When the dust collection assembly 400 is fitted onto the power supply handle 210 and supported by the corona assembly 300, the bottom of the dust collection assembly 400 applies downward pressure to the pressing post 331, thereby pressing the grounding tongue 330 into the assembly groove 2311 of the housing 231 of the docking assembly 230, so that the grounding tongue 330 and the grounding conductive post 232 in the assembly groove 2311 form a tight and stable electrical connection. This structure utilizes the assembly load of the dust collection component 400 to achieve the pressing and conduction of the grounding tongue 330 and the grounding conductive post 232, eliminating the need for additional fasteners. This simplifies the module assembly process, reduces assembly costs, and avoids grounding failure caused by loose fasteners. At the same time, it ensures the reliability of the grounding path of the corona component 300, providing a stable potential reference for the corona discharge of the generating electrode 320.

[0048] See Figures 7 to 10As shown, the dust collection component 400 is a structure for capturing charged dust. Its dust collection frame 410 is sleeved on the power supply handle 210 and supported on the corona component 300, serving as the installation support structure for the dust collection electrode 420. The frame design fixes the shape and position of the dust collection electrode 420, ensuring that a uniform electric field gap is formed between the dust collection electrode 420 and the generating electrode 320. At the same time, it transfers its own weight to the corona component 300 and the base 100, ensuring the hierarchical assembly stability of the entire module. The dust collection electrode 420 is connected to the first connector 233 and connected to a high voltage with the opposite polarity to that of the generating electrode 320, thereby forming a directional electrostatic field between the two electrodes. When charged dust particles flow through this electric field, they are adsorbed onto the surface of the dust collection electrode 420 under the action of the electric field force, ultimately achieving the separation and collection of dust.

[0049] In this embodiment, the dust collection frame 410 is provided with a second mounting hole 412 at its center that matches the shape of the outer surface of the power supply handle 210. Combined with the non-cylindrical surface structure design of the outer surface of the power supply handle 210, the matching second mounting hole 412 can form a shape coupling limit with the power supply handle 210. During the assembly process of the dust collection frame 410 being fitted onto the power supply handle 210, the circumferential rotation of the dust collection frame 410 relative to the power supply handle 210 can be strictly limited, ensuring that the dust collection electrode 420 on the dust collection frame 410 and the generating electrode 320 of the corona component 300 maintain a preset relative position, ensuring the uniformity of the electric field distribution between the two. At the same time, the shape-matching assembly structure can increase the connection and contact area between the dust collection frame 410 and the power supply handle 210, improve the assembly stability of the dust collection component 400, prevent the dust collection frame 410 from loosening or shifting during module operation, and further ensure the consistency of dust collection effect.

[0050] Specifically, the dust collection assembly 400 further includes an adapter assembly 430 and a roll film 440. The roll film 440 is connected to the dust collection frame 410, and one end of the roll film 440 is connected to the dust collection electrode 420. The adapter assembly 430 is disposed between the dust collection electrode 420 and the roll film 440 to electrically connect the dust collection electrode 420 and the roll film 440. The roll film 440 increases the dust adsorption area, improving the dust capacity of the dust collection module. Its wound structure facilitates disassembly, replacement, cleaning, and maintenance, reducing the module's operation and maintenance costs. The adapter assembly 430, disposed between the dust collection electrode 420 and the roll film 440, acts as an electrical connection medium, ensuring stable conductivity between them and thus providing dust adsorption capacity. This avoids localized electric field failure caused by insufficient conductivity between the roll film 440 and the dust collection electrode 420. In addition, the adapter assembly 430 can also provide structural support for the connection between the dust collection electrode 420 and the roll film 440, preventing the roll film 440 from falling off or shifting during winding or operation, and ensuring the operational stability of the dust collection assembly 400.

[0051] Furthermore, the adapter assembly 430 includes a fixing member 432 and an adapter piece 431. The adapter piece 431 includes a connecting portion 4311 and two pressing portions 4312. The dust collecting electrode 420 is connected to the connecting portion 4311 through the fixing member 432. The two pressing portions 4312 are disposed on the side of the connecting portion 4311 facing the roll film 440 and are symmetrically arranged on both sides of the connecting portion 4311. Both pressing portions 4312 abut against the roll film 440. The connecting part 4311 serves as the assembly carrier for the dust collecting electrode 420. The dust collecting electrode 420 is inserted and fastened to the connecting part 4311 through the fixing member 432. This connection method can achieve rigid fixation and stable electrical conduction between the dust collecting electrode 420 and the adapter piece 431, avoiding poor connection between the two during module operation. The two pressing parts 4312 are symmetrically arranged on the side of the connecting part 4311 facing the roll film 440, and there is an included angle between the two pressing parts 4312 so as to elastically abut against the surface of the roll film 440 respectively. Through the symmetrical pressing structure design, the connection area between the adapter piece 431 and the roll film 440 can be increased. At the same time, the elastic force of the pressing part 4312 is used to ensure that the two always remain tightly attached, thereby realizing the efficient conduction of the high voltage of the dust collecting electrode 420 to the roll film 440 through the adapter assembly 430.

[0052] Furthermore, in this embodiment, the two adapter pieces 431 are installed in two independent spaces, forming a physical isolation barrier. This ensures that the two poles with opposite voltage polarities are completely in independent environments, thus completely cutting off the creepage path between the two poles. From a structural design perspective, this avoids the creepage hazard caused by high voltage difference and ensures safe and stable power conduction between the dust collection electrode and the roll film.

[0053] Based on the above structure, the dust collection frame 410 in this embodiment is provided with a collecting electrode female seat 411, and the dust collection electrode 420 is disposed in the collecting electrode female seat 411. The first connector 233 can pass through the collecting electrode female seat 411 and is electrically connected to the dust collection electrode 420. The connecting part 4311 serves as the assembly carrier for the dust collection electrode 420. The dust collection electrode 420 passes through and is fastened to the connecting part 4311 via the fixing member 432. This connection method can achieve rigid fixation and stable electrical conduction between the dust collection electrode 420 and the adapter piece 431, avoiding poor connection problems during module operation. Two pressing parts 4312 are symmetrically arranged on the side of the connecting part 4311 facing the roll film 440, and both elastically abut against the surface of the roll film 440, achieving symmetrical pressing. The structural design increases the connection area between the adapter plate 431 and the roll film 440. At the same time, the elastic force of the pressing part 4312 ensures that the two remain tightly attached, thereby achieving efficient conduction of the high voltage of the dust collection electrode 420 to the roll film 440 through the adapter assembly 430. The roll film 440 is configured as a structure formed by winding two independent conductive films. The two conductive films are respectively connected to opposite high voltages, so that the roll film 440 itself forms an adsorption electric field, thereby ensuring the stability of the dust collection effect.

[0054] Furthermore, the concave structure of the collecting female base 411 can be fitted with the first connector 233, so that the connected first connector 233 is located in a sealed space, thereby preventing the phenomenon of flashover and creepage caused by moisture and dirt.

[0055] It should be noted that the corona frame 310 and the dust collection frame 410 in this embodiment are respectively provided with handles 500. During the module assembly stage, the operator can hold the handles 500 to achieve precise alignment and fitting of the corona frame 310 with the docking component 230 and the dust collection frame 410 with the power supply handle 210, avoiding component contamination or structural deformation caused by direct connection to the frame body; during the module maintenance stage, the corona component 300 or the dust collection component 400 can be quickly disassembled from the base 100 by pulling the handles 500, which facilitates cleaning of the generating electrode 320 of the corona component 300 and cleaning of the roll film 440 of the dust collection component 400, greatly improving the convenience of module maintenance.

[0056] In different implementations, the positions of the corona component and the dust collection component can be interchanged according to actual usage requirements, and the present invention does not impose specific limitations on them.

[0057] Example 3: See Figure 11 As shown, this embodiment provides an air purifier, which includes the aforementioned dust collection module, main unit 600, and coupler 700. The male coupling socket 710 of the coupler 700 is disposed on the main unit 600, and the female coupling socket 720 of the coupler 700 is disposed at the power supply terminal of the power supply handle 210 in the dust collection module. The male coupling socket 710 can be plugged into the female coupling socket 720 to connect the dust collection module and the main unit 600.

[0058] In summary, the power supply mechanism, dust collection module, and air purifier described in this invention creatively propose a tower-style vertical stacked structure composed of a base 100, a docking component 230, a corona component 300, and a dust collection component 400. This structure overcomes the limitations of traditional horizontal insertion structures. The corona frame 310 is directly fitted onto the housing 231 of the docking component 230, and the dust collection frame 410 is fitted onto the power supply handle 210 and supported on the corona component 300. Precise alignment of each component can be achieved without additional positioning straight edges or guide grooves. This not only breaks through the limitations of traditional cuboid modules on the shape of the equipment cabin, allowing it to adapt to diverse product designs such as round and cylindrical shapes, but also greatly simplifies the assembly steps. Users can quickly complete the installation simply by stacking the components using their own gravity, significantly reducing assembly difficulty and operational barriers. At the same time, it can effectively prevent flashover of high voltage electricity caused by moisture and dirt, and avoid the formation of conductive paths by leakage current traces, which could lead to short circuit failure of the high-voltage electrostatic dust collection system.

[0059] Furthermore, this application utilizes the downward pressure of gravity on the dust collection component 400 to ensure that the grounding tongue 330 of the corona component 300 and the grounding conductive post 232 are tightly fitted together, guaranteeing reliable conduction between the first connector 233 and the dust collection electrode 420. This replaces the defects of traditional side spring connections that are easily affected by assembly tolerances and long-term wear. During equipment operation, the connection status of each component will not loosen due to vibration, deformation, or other factors, and a stable high-voltage electrostatic field can always be maintained. This ensures that the corona ionization and particulate matter capture effects are stable and long-lasting, effectively improving the operational reliability and service life of the dust collection module.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
