Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an electrostatic dust removal and self-cleaning device for the dust collection plate of an air purifier. Background Technology

[0002] An air purifier is a device that can adsorb, decompose, or transform various air pollutants. It is mainly used to improve indoor air cleanliness and is primarily used in home and commercial settings. The core component of an air purifier is the dust collection plate, which accumulates a lot of dust on its surface after prolonged use and therefore needs to be cleaned regularly.

[0003] Existing air purifier dust collection plates require periodic disassembly and cleaning, which is time-consuming and labor-intensive. Some electrostatic self-cleaning devices, however, have limitations in their effectiveness because dust accumulates mainly on the outer surface of the dust collection plate, and the plate cannot be flipped over. Furthermore, the self-cleaning process cannot reliably shut off the air purifier's exhaust, leading to dust leakage and reduced air purification efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problems of time-consuming and laborious disassembly and cleaning of the dust collection plate, the inability to flip the dust collection plate during self-cleaning, which reduces the effectiveness of electrostatic self-cleaning, and the inability to stably close the exhaust vent of the air purifier during self-cleaning, which leads to dust leakage and reduces the air purification effect. This invention provides an electrostatic dust removal and self-cleaning device for the dust collection plate of an air purifier.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: An electrostatic dust removal and self-cleaning device for an air purifier dust collection plate includes a cylindrical body. A semi-circular cover is uniformly fixedly connected to the outer periphery of the cylindrical body. Air inlets are uniformly opened on the outer periphery of the semi-circular cover. A dust collection plate is rotatably connected to the inner part of the cylindrical body where the semi-circular cover connects to the cylindrical body. A gear is fixedly installed at the top of the dust collection plate. A partition is fixedly connected to the inner side of the top of the cylindrical body. Two motors are fixedly installed at the center of the partition. A turntable is driven to the bottom of the two motors. Gear rings are uniformly fixedly connected to the outer periphery of the turntable. A vertically penetrating arc-shaped groove is uniformly opened on the outer periphery of the turntable. Fan blades are driven to the top of the two motors. A second arc-shaped groove is uniformly opened on the outer periphery of the partition. An exhaust port is opened at the top of the cylindrical body. An electrostatic rod is fixedly installed at the center of the bottom of the turntable.

[0006] Furthermore, the inner diameter of the semicircular cover is larger than the rotation diameter of the dust collection plate, allowing the dust collection plate to rotate inside the semicircular cover.

[0007] Furthermore, the transmission shafts on the upper and lower sides of the dual motors are controlled separately, and are used to drive the fan blades and the turntable to rotate respectively.

[0008] Furthermore, during the rotation of the turntable, the toothed ring on the outer periphery of the turntable can mesh with the gear, and the number of teeth on the toothed ring is half the number of teeth on the gear. Therefore, during the rotation of the turntable, the meshing of the toothed ring and the gear can drive the gear and the dust collection plate to rotate 180°.

[0009] Furthermore, the top of the turntable is attached to the bottom of the partition plate, and during air purification, the second arc-shaped groove on the partition plate aligns with the first arc-shaped groove on the turntable. As the turntable rotates, the second arc-shaped groove on the partition plate and the first arc-shaped groove on the turntable are misaligned and closed after the outer gear ring drives the gear to rotate. Therefore, during air purification, the purified air can be ensured to flow upward normally, and during electrostatic dust removal, the top of the cylinder can be stably sealed.

[0010] Furthermore, a collection box is slidably connected to the bottom of the cylinder, and a handle is fixedly installed on the right end of the collection box. A material drop trough is provided in the center above the collection box at the bottom of the cylinder, and the diameter of the material drop trough is larger than the diameter of the electrostatic bar, so that after the electrostatic bar is de-energized, the dust adsorbed on the surface of the electrostatic bar can fall downward and fall into the collection box through the material drop trough for collection.

[0011] Furthermore, support legs are evenly fixedly installed at the bottom end of the cylinder to facilitate the suspended placement of the cylinder.

[0012] The beneficial effects of this utility model are as follows: This invention, through the design of an electrostatic bar inside the cylinder, combined with a collection box at the bottom, enables electrostatic dust removal and cleaning of the dust collection plate inside the cylinder. Compared to disassembly and cleaning, this method is more time-saving and labor-saving. The engagement of the gear ring and gears on the turntable allows the dust collection plate to be flipped during electrostatic dust removal and cleaning, thereby improving the cleaning effect. At the same time, the engagement of the first arc groove on the turntable and the second arc groove on the partition plate allows the partition to be sealed during electrostatic dust removal and cleaning, thus preventing dust from easily leaking out during the cleaning process and ensuring the air purification effect.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0016] A preferred embodiment of the present invention, an electrostatic dust removal and self-cleaning device for an air purifier dust collection plate, will be described in detail below, such as... Figures 1-7 As shown, an electrostatic dust removal self-cleaning device for an air purifier dust collection plate includes a cylinder 1. A semi-circular cover 2 is uniformly fixedly connected to the outer periphery of the cylinder 1. Air inlet holes 3 are uniformly opened on the outer periphery of the semi-circular cover 2. A dust collection plate 4 is rotatably connected to the connection between the semi-circular cover 2 and the cylinder 1 inside the cylinder 1. The inner diameter of the semi-circular cover 2 is larger than the rotation diameter of the dust collection plate 4, so that the dust collection plate 4 can rotate inside the semi-circular cover 2.

[0017] A gear 5 is fixedly installed at the top of the dust collection plate 4. A partition 6 is fixedly connected to the inner side of the top of the cylinder 1. A dual motor 7 is fixedly installed at the center of the partition 6. The transmission shafts on the upper and lower sides of the dual motor 7 are controlled separately to drive the fan blade 11 and the turntable 8 to rotate. The bottom of the dual motor 7 is connected to the turntable 8. Gear rings 9 are evenly fixedly connected to the outer periphery of the turntable 8. During the rotation of the turntable 8, the gear rings 9 on the outer periphery of the turntable 8 can mesh with the gear 5. The number of teeth on the gear rings 9 is half the number of teeth on the gear 5. Therefore, during the rotation of the turntable 8, the meshing of the gear rings 9 and the gear 5 can drive the gear 5 and the dust collection plate 4 to rotate 180°.

[0018] The outer periphery of the turntable 8 is evenly provided with arc-shaped grooves 10 running vertically through it. The top of the dual motors 7 is connected to the fan blades 11. The outer periphery of the partition plate 6 is evenly provided with arc-shaped grooves 12. The top of the turntable 8 is attached to the bottom of the partition plate 6. When purifying the air, the arc-shaped grooves 12 on the partition plate 6 are aligned with the arc-shaped grooves 10 on the turntable 8. As the turntable 8 rotates, after the gear 5 driven by the outer toothed ring 9 rotates, the arc-shaped grooves 12 on the partition plate 6 and the arc-shaped grooves 10 on the turntable 8 are misaligned and closed. Therefore, when purifying the air, it can ensure that the purified air flows upward normally. When performing electrostatic dust removal, it can stably seal the top of the cylinder 1.

[0019] The top of the cylinder 1 is provided with an exhaust hole 13. An electrostatic rod 14 is fixedly installed at the center of the bottom of the turntable 8. A collection box 15 is slidably connected to the bottom of the cylinder 1. A handle 151 is fixedly installed at the right end of the collection box 15. A material drop trough 16 is provided at the center above the collection box 15 at the bottom of the cylinder 1. The diameter of the material drop trough 16 is larger than the diameter of the electrostatic rod 14, so that when the electrostatic rod 14 is de-energized, the dust adsorbed on the surface of the electrostatic rod 14 can fall downward and fall into the collection box 15 through the material drop trough 16 for collection. Support legs 17 are evenly fixedly installed at the bottom of the cylinder 1 to facilitate the suspension of the cylinder 1.

[0020] The working principle of this utility model is as follows: During air purification, the dual motors 7 are activated to drive the fan blades 11 to rotate. As the fan blades 11 rotate, they blow air upwards, drawing air from the bottom through the air inlet 3 on the semi-circular cover 2. The air then passes through the dust collection plate 4 and enters the interior of the cylinder 1, where the dust collection plate 4 purifies the air. The purified air then passes through the aligned arc-shaped grooves 10 and 12 and is discharged upwards through the exhaust port 13, thus achieving air purification.

[0021] When the dust collection plate 4 needs to be cleaned, the dual motors 7 stop driving the fan blades 11 to rotate and drive the turntable 8 to rotate. During the rotation of the turntable 8, the meshing of the outer toothed ring 9 and the gear 5, and the design that the number of teeth of the toothed ring 9 is half the number of teeth of the gear 5, can drive the gear 5 and the dust collection plate 4 to rotate 180°, thereby turning the dust collection plate 4 over. During the rotation of the turntable 8, the arc groove 10 and the arc groove 2 12 can also be misaligned and closed, thereby preventing the air inside the cylinder 1 from passing upward through the partition 6.

[0022] After the partition 6 is closed, the electrostatic bar 14 is energized to adsorb the dust on the surface of the dust collection plate 4 after it is flipped. After the electrostatic adsorption is completed, the electrostatic bar 14 is de-energized, and the dust adsorbed on the surface of the electrostatic bar 14 will fall downward and fall into the collection box 15 through the drop chute 16 for collection.

[0023] After the dust collection is completed, the dual motors 7 drive the turntable 8 to reverse, causing the dust collection plate 4 to flip over again and start adsorption again. The turntable 8 also drives the arc groove 10 to realign with the arc groove 12. Then, the dual motors 7 drive the fan blades 11 to rotate, so that the dust collection plate 4 can re-purify the air after dust removal, thus ensuring the purification effect.

[0024] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
