Description

Technical Field

[0001] The present application relates to the field of air purification equipment, and in particular, to an air purifier. Background Art

[0002] Existing air purifiers based on electrostatic dust collection technology generally include multiple modules such as a generator module, a collector module, a primary network, a fan and a casing, and the multiple modules are generally installed and designed in a vertical or horizontal stacking manner. Therefore, the existing air purifiers are large in size and occupy a large space. For rooms with smaller areas, they pose greater obstacles and restrictions, and the product user experience is poor. In addition, the two stacking structures limit the scope of the product's appearance industrial design and reduce the product user experience. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide an air purifier, which has a compact structure and a small space volume, and can improve the comfort of product use and user experience.

[0004] The embodiment itself provides an air purifier, which includes a shell, a generating pole winding, a dust collecting impeller and a motor, the shell includes an air inlet and an air outlet, and the air inlet and the air outlet form an air flow channel between the shell; the generating pole winding is arranged upstream of the air flow channel, and the generating pole winding is connected to positive high voltage electricity; the dust collecting impeller is arranged downstream of the air flow channel, including a plurality of collecting pole blades, and the collecting pole blades are connected to negative high voltage electricity; the motor is installed on the shell, and is used to drive the dust collecting impeller to rotate.

[0005] In the above implementation process, the air flows from the air inlet to the air outlet under the action of the dust collecting impeller. When the air circulates in the air flow channel between the air inlet and the air outlet, it will first pass through the upstream generating pole winding. Since the generating pole winding is connected to positive high voltage electricity, a plasma field will be formed around the generating pole winding under the action of high voltage ionization, so that the surrounding air molecules are ionized and carry positive charges. The ionized air accelerates and collides with other particles and carries positive charges under the action of the electric field force formed between the generating pole winding connected to positive high voltage electricity and the dust collecting impeller connected to negative high voltage electricity. Through a series of snowball avalanche effects, the dust and bacteria passing through the electric field are charged and move toward the dust collecting impeller, and finally adsorbed by the dust collecting impeller connected to negative high voltage electricity. The above air purifier integrates the collecting pole module into the impeller to form a dust collecting impeller, which reduces the number of component modules of the air purifier, simplifies the internal structure of the air purifier, reduces the space volume of the space purifier, expands the scope of the appearance design of subsequent air purifiers, and improves the product comfort and user experience.

[0006] In a possible implementation, the dust collecting impeller is a multi-blade centrifugal impeller, the generating pole winding is wound in a cylindrical shape, and the generating pole winding is nested in the dust collecting impeller.

[0007] In the above implementation process, the dust collecting impeller adopts the structure of a multi-blade centrifugal impeller, which is cylindrical in structure. The pole winding is also designed to be cylindrical, and the pole winding is nested in the dust collecting impeller. The pole winding and the dust collecting impeller are assembled in a nested manner, which reduces the overall space occupied compared to the vertical or horizontal stacking assembly form in the prior art.

[0008] In a possible implementation, the axis of the dust collecting impeller coincides with the axis of the generating pole winding.

[0009] In the above implementation process, the axis of the dust collecting impeller is arranged to coincide with the axis of the generating pole winding, so that the radial distance between the generating pole on the generating pole winding and the collecting pole blade on the dust collecting impeller is equal everywhere, so that the electric field force between the generating pole wire winding and the dust collecting impeller is evenly distributed along the circumference, which can improve the dust collection effect and air purification effect.

[0010] In a possible implementation, the dust collecting impeller further includes a plurality of repelling pole blades, and the plurality of repelling pole blades are spaced apart from the plurality of collecting pole blades.

[0011] In the above implementation process, repelling electrode blades are arranged on the dust collecting impeller, and the repelling electrode blades are connected to positive high voltage electricity. When the dust with positive charge ionized by the generating electrode winding approaches the repelling electrode blades, the positively charged dust repels the repelling electrode blades connected to the positive high voltage electricity. Under the action of the electric field force, the repelling electrode blades push the dust to move in the direction of the collecting electrode blades, thereby improving the dust collection rate and the air purification effect.

[0012] In a possible implementation, the dust collecting impeller also includes an insulating bracket, which includes a front ring, a rear ring and a connecting frame fixedly connected to the front ring and the rear ring, the axes of the front ring and the rear ring coincide, the output shaft of the motor is fixedly connected to the front ring, one end of the repulsion pole blade is fixedly connected to the front ring, and the other end is detachably connected to the rear ring, and one end of the collection pole blade is fixedly connected to the rear ring, and the other end is detachably connected to the front ring.

[0013] In the above implementation process, the repelling electrode blade is fixedly connected to the front ring and detachably connected to the rear ring, that is, the repelling electrode blade is integrated with the front ring; the collecting electrode blade is fixedly connected to the rear ring and detachably connected to the front ring, that is, the collecting electrode blade is integrated with the rear ring. Therefore, the collecting electrode blade and the repelling electrode blade can be disassembled, and the gap between the collecting electrode blades becomes larger after disassembly, and one end of the collecting electrode blade is not blocked and is in an open state, which is convenient for cleaning. At the same time, the detachable structure facilitates the subsequent maintenance of the dust collecting impeller.

[0014] In a possible implementation, the generating pole winding includes a circular ring bracket and a plurality of generating pole wires, the circular ring bracket includes a front ring, a rear ring and a connector fixedly connecting the front ring and the rear ring, and each generating pole wire passes around the front ring and the rear ring along the axial direction of the circular ring bracket.

[0015] In the above implementation process, the generating pole winding is formed into a cylindrical shape by winding the generating pole wire on a simple circular ring bracket, and the circular ring bracket only includes a front ring, a rear ring and a connecting piece, which has a simple structure, is easy to manufacture and has a low cost.

[0016] In a possible implementation, the number of the generating pole wires is the same as the number of the collecting pole blades.

[0017] In the above implementation process, since the dust ionized by the generating electrode wire and carried with positive charge will eventually reach the collecting electrode blades and be collected by the collecting blades, when the number of collecting electrode blades is designed to be equal to the number of generating electrode wires wound on the generating electrode winding, the requirements of dust collection and air purification can be met without causing congestion on the dust collecting impeller or the generating electrode winding structure.

[0018] In a possible implementation, the potential difference between the generating electrode winding and the collecting electrode blade is U, the distance between the generating electrode wire and the collecting electrode blade is L, and U / L is less than 10^7V / M.

[0019] In the above implementation process, the relationship between the potential difference and the distance between the generating electrode wire and the collecting electrode blade is limited to U / L less than 10^7V / M, which can ensure the effect of the electric field force between the generating electrode wire and the collecting electrode blade and the dust collection effect.

[0020] In a possible implementation, the insulating bracket also includes a second impeller, which is arranged on the front ring. The second impeller includes a transmission ring and a plurality of second blades. The transmission ring is coaxially arranged with the front ring. One end of the second blade is fixedly connected to the front ring, and the other end extends radially inward along the front ring and is fixedly connected to the transmission ring. The transmission ring is fixedly mounted on the output shaft of the motor.

[0021] In the above implementation process, a second impeller is arranged between the front ring of the dust collecting impeller and the motor. The dust collecting impeller includes two impellers working simultaneously, that is, the dust collecting impeller is designed as a composite impeller, which improves the working efficiency of the dust collecting impeller, accelerates the circulation speed of air in the air flow channel, and improves the dust collection efficiency.

[0022] In one possible implementation, the shell is a volute, which includes a front plate, a rear plate, and a volute tongue arranged between the front plate and the rear plate, the air inlet is arranged on the front plate of the volute, the air outlet is arranged on the volute tongue, and the axis of the generating pole winding is perpendicular to the front plate.

[0023] In the above implementation process, since the dust collecting impeller and the pole winding are both cylindrical structures, the shell is designed as a volute according to the structural characteristics of the dust collecting impeller and the pole winding. The volute can fit with the nested dust collecting impeller and the pole winding, thereby reducing the spatial volume of the air purifier. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0032] Please refer to Figure 1 and Figure 3 , Figure 1 An exploded structural diagram of an air purifier provided in an embodiment of the present application, Figure 3 An overall structural diagram of an air purifier provided for an embodiment of the present application (the arrows in the figure indicate the direction of air flow in the air flow channel). The embodiment itself provides an air purifier, which includes a housing 100, a generating pole winding 200, a dust collecting impeller 300 and a motor 400, the housing 100 includes an air inlet 110 and an air outlet 120, and the air inlet 110 and the air outlet 120 form an air flow channel between the housing 100; the generating pole winding 200 is arranged upstream of the air flow channel, and the generating pole winding 200 is connected to positive high voltage electricity; the dust collecting impeller 300 is arranged downstream of the air flow channel, including a plurality of collecting pole blades 310, and the collecting pole blades 310 are connected to negative high voltage electricity; the motor 400 is installed on the housing 100, and is used to drive the dust collecting impeller 300 to rotate.

[0033] In the above implementation process, the air flows from the air inlet 110 to the air outlet 120 under the action of the dust collecting impeller 300. When the air flows in the air flow channel between the air inlet 110 and the air outlet 120, it will first pass through the upstream generating pole winding 200. Since the generating pole winding 200 is connected to positive high voltage electricity, a plasma field will be formed around the generating pole winding 200 under the action of high voltage ionization, so that the surrounding air molecules are ionized and carry positive charges. The ionized air is accelerated under the action of the electric field force formed between the generating pole winding 200 connected to positive high voltage electricity and the dust collecting impeller 300 connected to negative high voltage electricity, collides with other particles and makes other particles carry positive charges. Through a series of snowball avalanche effects, the dust and bacteria passing through the electric field are charged and move toward the dust collecting impeller 300, and are finally adsorbed by the dust collecting impeller 300 connected to negative high voltage electricity. The above-mentioned air purifier integrates the collecting electrode module into the impeller to form the dust collecting impeller 300, which reduces the number of component modules of the air purifier, simplifies the internal structure of the air purifier, reduces the space volume of the space purifier, expands the scope of appearance design of subsequent air purifiers, and improves product comfort and user experience.

[0034] In a possible implementation, a primary net 500 is provided at the air inlet 110 on the shell 100 , and the primary net 500 can intercept large particles of dust and hair, etc., to prevent the hair and the like from being retained in the generating pole wire 220 winding and damaging the structure of the generating pole winding 200 .

[0035] In a possible implementation, the dust collecting impeller 300 is a multi-blade centrifugal impeller, the generating pole winding 200 is wound in a cylindrical shape, and the generating pole winding 200 is nested in the dust collecting impeller 300 .

[0036] In the above implementation process, the dust collecting impeller 300 adopts the structure of a multi-blade centrifugal impeller, which is cylindrical in structure, and the pole winding 200 is also designed to be cylindrical, and the pole winding 200 is nested in the dust collecting impeller 300. The pole winding 200 and the dust collecting impeller 300 are assembled in a nested manner, which reduces the overall space occupied compared to the vertical or horizontal stacking assembly form in the prior art.

[0037] Please refer to Figure 2 , Figure 2 The present invention provides an assembly structure diagram of a dust collecting impeller and a generating pole winding. In a possible implementation, the axis of the dust collecting impeller 300 coincides with the axis of the generating pole winding 200.

[0038] In the above implementation process, the axis of the dust collecting impeller 300 is arranged to coincide with the axis of the generating pole winding 200, so that the radial distance between the generating pole on the generating pole winding 200 and the collecting pole blade 310 on the dust collecting impeller 300 is equal everywhere, so that the electric field force between the generating pole wire 220 winding and the dust collecting impeller 300 is evenly distributed along the circumference, which can improve the dust collection effect and the air purification effect.

[0039] In a possible implementation, the dust collecting impeller 300 further includes a plurality of repelling pole blades 320 , and the plurality of repelling pole blades 320 are arranged at intervals from the plurality of collecting pole blades 310 .

[0040] In the above implementation process, a repelling pole blade 320 is provided on the dust collecting impeller 300, and the repelling pole blade 320 is connected to positive high voltage electricity. When the dust with positive charge ionized by the generating pole winding 200 approaches the repelling pole blade 320, the positively charged dust repels the repelling pole blade 320 connected to the positive high voltage electricity. Under the action of the electric field force, the repelling pole blade 320 pushes the dust to move in the direction of the collecting pole blade 310, thereby improving the dust collection rate and the air purification effect.

[0041] In one possible implementation, see Figure 4 , Figure 4An exploded view of a dust collecting impeller provided in an embodiment of the present application, the dust collecting impeller 300 also includes an insulating bracket 330, the insulating bracket 330 includes a front ring 340, a rear ring 350 and a connecting frame 380 fixedly connecting the front ring 340 and the rear ring 350, the axes of the front ring 340 and the rear ring 350 coincide, the output shaft of the motor 400 is fixedly connected to the front ring 340, one end of the repelling pole blade 320 is fixedly connected to the front ring 340, and the other end is detachably connected to the rear ring 350, and one end of the collecting pole blade 310 is fixedly connected to the rear ring 350, and the other end is detachably connected to the front ring 340.

[0042] In the above implementation process, the repelling electrode blade 320 is fixedly connected to the front ring 340 and detachably connected to the rear ring 350, that is, the repelling electrode blade 320 and the front ring 340 are integrated; the collecting electrode blade 310 is fixedly connected to the rear ring 350 and detachably connected to the front ring 340, that is, the collecting electrode blade 310 and the rear ring 350 are integrated. Therefore, the collecting electrode blade 310 and the repelling electrode blade 320 can be disassembled, and the gap between the collecting electrode blades 310 after disassembly becomes larger, and one end of the collecting electrode blade 310 is not blocked and is in an open state, which is convenient for cleaning using daily cleaning methods, such as using a brush, a scouring pad, a sponge, etc., which can improve the user's product experience. At the same time, the detachable structure facilitates the subsequent maintenance of the dust collecting impeller 300.

[0043] In one possible implementation, the generating pole winding 200 includes a circular ring bracket 210 and a plurality of generating pole wires 220. The circular ring bracket 210 includes a front ring, a rear ring, and a connector that fixes the front ring and the rear ring. Each generating pole wire 220 passes around the front ring and the rear ring along the axial direction of the circular ring bracket 210.

[0044] In the above implementation process, the pole winding 200 uses a pole wire 220 wound on a simple circular bracket 210 to form a cylindrical shape, and the circular bracket 210 only includes a front ring, a rear ring and a connecting piece, which has a simple structure, is easy to manufacture and has a low cost.

[0045] It should be noted that in order to ensure that the air can pass through the generating pole winding 200 along the radial direction of the generating pole winding 200 to reach the dust collecting impeller 300, that is, to ensure the smoothness of the air flow channel, the connecting piece for connecting the front ring and the rear ring on the ring bracket 210 can be a thinner rod, and the two ends of the thin rod are respectively connected to the front ring and the rear ring. The number of thin rods can be 2-4, and multiple thin rods can be arranged along the circumference array between the rings, which is conducive to the stability of the ring bracket 210 structure.

[0046] In a possible implementation, the number of the generating pole wires 220 is the same as the number of the collecting pole blades 310 .

[0047] In the above implementation process, since the dust ionized by the generating electrode wire 220 and carrying positive charge will eventually reach the collecting electrode blade 310 and be collected by the collecting blade, when the number of collecting electrode blades 310 is designed to be equal to the number of generating electrode wires 220 wound on the generating electrode winding 200, the requirements of dust collection and air purification can be met without causing congestion in the structure of the dust collecting impeller 300 or the generating electrode winding 200.

[0048] In a possible implementation, the potential difference between the generating pole winding 200 and the collecting pole blade 310 is U, the distance between the generating pole wire 220 and the collecting pole blade 310 is L, and U / L is less than 10^7V / M.

[0049] In the above implementation process, the relationship between the potential difference and the distance between the generating electrode wire 220 and the collecting electrode blade 310 is limited to U / L less than 10^7V / M, which can ensure the effect of the electric field force between the generating electrode wire 220 and the collecting electrode blade 310 and the dust collection effect.

[0050] In one possible implementation, the insulating bracket 330 also includes a second impeller, which is arranged on the front ring 340. The second impeller includes a transmission ring 360 and a plurality of second blades 370. The transmission ring 360 is coaxially arranged with the front ring 340. One end of the second blade 370 is fixedly connected to the front ring 340, and the other end extends radially inward along the front ring 340 and is fixedly connected to the transmission ring 360. The transmission ring 360 is fixedly installed on the output shaft of the motor 400.

[0051] In the above implementation process, a second impeller is arranged between the front ring 340 of the dust collecting impeller 300 and the motor 400. The dust collecting impeller 300 includes two impellers working simultaneously, that is, the dust collecting impeller 300 is designed as a composite impeller, which improves the working efficiency of the dust collecting impeller 300, accelerates the circulation speed of air in the air flow channel, and improves the dust collection efficiency.

[0052] In one possible implementation, the shell 100 is a volute, which includes a front plate 130, a rear plate 140, and a volute tongue 150 arranged between the front plate 130 and the rear plate 140, the air inlet 110 is arranged on the front plate 130 of the volute, the air outlet 120 is arranged on the volute tongue 150, and the axis of the pole winding 200 is perpendicular to the front plate 130.

[0053] In the above implementation process, since the dust collecting impeller 300 and the generating pole winding 200 are both cylindrical structures, the housing 100 is designed as a volute according to the structural characteristics of the dust collecting impeller 300 and the generating pole winding 200, and the volute can fit with the dust collecting impeller 300 and the generating pole winding 200 nested together, thereby reducing the spatial volume of the air purifier. The axis of the generating pole winding 200 and the dust collecting impeller 300 is perpendicular to the front plate 130, that is, perpendicular to the air inlet 110 on the front plate 130, and the air enters the inner ring of the generating pole winding 200 from the air inlet 110 along the axial direction of the generating pole winding 200, and then under the action of the centrifugal force of the dust collecting impeller 300, it passes through the generating pole wire 220 and the collecting pole blade 310 of the generating pole winding 200 in the radial direction in sequence, and then is purified.

[0054] It should be noted that the housing 100 may also be in the shape of a disc, with the air inlet 110 disposed on one end face of the disc and the air outlet 120 disposed on the circumferential side of the disc. The air purifier using the disc-shaped housing 100 is similar in appearance to a wall clock or clock, and can be hung on a wall or cabinet, saving space and improving the user's product experience.
