Description

Technical Field

[0001] This utility model relates to the field of ion wind air purifier technology, and in particular to a high-voltage electrostatic air purification module and an ion wind air purifier. Background Technology

[0002] The working principle of an electrostatic dust removal ion wind air purifier is mainly to generate corona discharge through a high-voltage electric field, producing ion wind and avalanche effect, causing air to flow in from the corona electrode and out from the dust collection electrode, thereby adsorbing dust and germs on the dust collection plate to achieve the effect of dust removal, sterilization and air purification.

[0003] The shortcomings of existing electrostatic dust removal ion air purifiers are that they rely solely on their own generated ion wind speed and low wind pressure, resulting in a limited range of fresh air delivery and a limited purification effect per unit time. Furthermore, simply increasing the voltage will ionize the air, producing ozone and nitrogen oxides, which will actually affect the purification effect. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a high-voltage electrostatic air purification module and an ion wind air purifier.

[0005] A high-voltage electrostatic air purification module is disclosed, which is applied to an ion wind air purifier. The module includes a power supply, an emitting mesh equipped with metal wires, and a collecting mesh equipped with a dust collection plate. The emitting mesh and the collecting mesh are arranged parallel to each other, and the distance between them is within a preset range. The power supply powers the metal wires and the dust collection plate. When the airflow of the ion wind air purifier is set to a first preset value, the voltage of the power supply is proportional to the distance between the emitting mesh and the collecting mesh within a preset voltage range. The preset range is between 5 mm and 200 mm, and the preset voltage range is between 15000V and 43000V.

[0006] An ion wind air purifier includes a main body and a high-voltage electrostatic air purification module as described above; both the emitting net and the collecting net are mounted on the main body.

[0007] The high-voltage electrostatic air purification module and ion wind air purifier provided by this utility model have an flexibly adjustable spacing between the emitting and collecting nets, which can be set within the power supply voltage adjustment range according to the air volume requirements. This solves the problem that unilaterally increasing the voltage in the prior art will generate ozone and nitrogen oxides. As a result, the ion wind air purifier based on this high-voltage electrostatic air purification module has more flexible design space to improve wind speed and wind pressure, thereby achieving better air purification effect.

[0016] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] A high-voltage electrostatic air purification module and an ion wind air purifier are provided, such as Figures 1 to 6 As shown, the high-voltage electrostatic air purification module includes a power supply, an emitting net 1 equipped with metal wires 11, and a collecting net 2 equipped with a dust collection plate 21; the emitting net and the collecting net are arranged parallel to each other, and the distance between them is within a preset range; the power supply is used to power the metal wires and the dust collection plate; when the air volume of the ion wind air purifier is set to a first preset value, the voltage value of the power supply is proportional to the distance between the emitting net and the collecting net within the preset voltage range; the preset range is between 5 mm and 200 mm, and the preset voltage range is between 15000V and 43000V.

[0018] The emitting net corresponds to the positive electrode, and the collecting net corresponds to the negative electrode. When energized, corona discharge is formed on the metal wires (also called emitting wires) on the emitting net, generating ion wind, and the air flows out through the dust collection plate on the collecting net.

[0019] Specifically, the first preset value for the airflow is 0.8 m / s. When the power supply voltage is 24000V, the optimal distance between the transmitting and collecting nets (i.e., between the metal wire and the dust collection plate) is 38 mm; when the power supply voltage is 26000V, the optimal distance is 45 mm; when the power supply voltage is 28000V, the optimal distance is 51 mm; and when the power supply voltage is 30000V, the optimal distance is 58 mm. Since the high-voltage electrostatic air purification module is based on unpowered airflow, the airflow is directly related to the voltage and the distance between the metal wire and the dust collection plate. That is, within the preset voltage range, the voltage value is directly proportional to the distance between the transmitting and collecting nets: the greater the distance between the transmitting and collecting nets, the higher the voltage requirement; conversely, the smaller the distance, the lower the voltage requirement. The range of motion between the metal wire and the dust collection plate is between 5 mm and 200 mm, and the voltage range is between 15000V and 43000V.

[0020] Furthermore, the transmitting net includes a wire frame 12; the metal wire is a single piece, and is integrally woven into a wire mesh in a first preset shape and assembled on the wire frame. Existing transmitting nets use multiple metal wires, which is not only cumbersome and complex for point-to-point installation but also more expensive. In this embodiment, the metal wire is set as a single piece, such as forming a wire mesh around the mounting points or tracks on the transmitting net in an S-shape or other shape. Installation can be completed simply by fixing both ends of the metal wire, making installation simple and efficient. This not only saves on the processing cost of the metal wire but also saves on conductive components.

[0021] Furthermore, the collection net includes a bottom shell 22; the number of dust collection plates is one, and it is in the shape of a metal strip; the metal strip dust collection plate is integrally assembled on the bottom shell in a second preset shape. In this embodiment, similar to the embodiment with a single metal wire, the existing multiple dust collection plates are improved into a whole metal strip shape, assembled in an S-shape or other shapes, which not only facilitates installation but also saves costs.

[0022] Furthermore, the dust collection plate comprises multiple pieces, each of which is horizontally arranged and the pieces are spaced vertically apart; the metal wire comprises multiple strands, each of which is vertically arranged and the strands are spaced horizontally apart; that is, the metal wires are all arranged perpendicularly to the dust collection plate at a 90° angle.

[0023] Furthermore, the transmitting net includes a wire frame 12 and a transmitting net cover 16, with a transmitting net silicone sleeve 17 installed inside the transmitting net cover. The wire frame is made of plastic; the wire frame is equipped with a high-voltage resistant quick-connect female connector 13 and a spring bracket 14; one end of the metal wire is connected to the high-voltage resistant quick-connect female connector, and the other end is connected to the spring bracket via a spring; a groove is provided on the wire frame corresponding to the wire outlet to accommodate the metal wire without contacting it.

[0024] In this embodiment, one end of the metal wire is attached to the female end and wraps around the inner track of the wire frame several times to form a wire mesh. The other end of the metal wire is attached to a spring support via a spring. Under the action of the spring's extension force, the metal wire is tightened, solving the difficulties of slow wire feeding and loose wire tension during production. Simultaneously, because the metal wire releases a large number of ions during operation, these ions cannot move quickly and tend to accumulate, accelerating the oxidation of the metal wire and forming a discontinuous oxide ring, making the metal wire prone to breakage. The groove at the wire exit is much larger than the metal wire, facilitating the rapid movement of the released ions and preventing them from piling up, thus ensuring the metal wire is less prone to breakage.

[0025] Furthermore, the collection net includes a bottom shell 22 and a collection net cover 26; the bottom shell has multiple opening slots 23, and a conductive metal sheet 24 is disposed inside the bottom shell; the dust collection plate consists of multiple arched metal sheets; the multiple arched metal sheets are respectively inserted into the opening slots and connected to the conductive metal sheet. In this embodiment, the opening slots facilitate quick assembly of the arched metal sheets, and when the arched metal sheets are inserted, they are connected to the conductive metal sheet, thus achieving the effect of quick assembly of the collection net, saving time and labor.

[0026] Furthermore, the upper or lower surface of the collection net is provided with protrusions 25, which are dot-shaped or strip-shaped. During assembly, the upper or lower surface of the collection net will contact the purifier body. Since it is a surface-to-surface contact, the resistance during sliding is large. Therefore, by changing the contact from surface to point, the resistance during sliding is reduced, and the tightness of the collection net when plugging and unplugging is also appropriate. At the same time, by reducing the contact area between the collection net and the body, the conductivity of the body is reduced. The protrusions include, but are not limited to, raised dots or raised strips, such as prismatic strips.

[0027] Furthermore, the collection net includes a pin assembly 3, which includes an insulating cover 31, a bracket 32, and a metal pin 33 mounted on the bracket. One end of the metal pin is fixed to the power cord by a nut, and the other end contacts a conductive metal sheet via a spring. The insulating cover is mounted on the nut and fixes the metal pin. In this embodiment, the metal pin is installed inside the bracket, with one end of the power cord fixed to the metal pin by a nut, and the other end pressed against the metal of the collection net by the spring. The upper end of the nut is provided with a pin insulating cover, which fixes the metal pin to the main body. This design solves the problem of the collection net being able to quickly and unobstructedly connect to the power supply while ensuring no leakage and ensuring safe operation of the machine.

[0028] The ion wind air purifier includes a main body 4 and the aforementioned high-voltage electrostatic air purification module; both the emission grid and the collection grid are mounted on the main body.

[0029] Furthermore, the main body is provided with two L-shaped buckles 5: an upper buckle and a lower buckle. One end of the L-shaped buckle is locked to the main body by a magnetic clamp 51, and the other end is provided with an anti-detachment protrusion 52. A corresponding groove is opened in the buckle on the main body. The anti-detachment protrusion prevents the collection net from falling out after it is assembled onto the main body. In this embodiment, the buckles are components that prevent the collection net from falling out. When the collection net is placed into the main body, the buckles are pressed into the grooves, and under the action of the protrusions, the buckles are locked, and the collection net is fixed inside the main body. This buckle design is simple, easy to assemble, and effective; it is both simple and important.

[0030] Furthermore, the main body is equipped with a male connector, and the transmitting net is equipped with a female connector that matches the male connector. When the transmitting net is assembled onto the main body, the male connector and the female connector are connected and fixed. In this embodiment, since the transmitting net is equipped with a female connector and the main body is equipped with a male connector, during assembly, it is only necessary to align the side of the transmitting net equipped with the female connector with the male connector on the main body and push it into place with force, which is simple and convenient.

[0031] Furthermore, the ion wind air purifier also includes a front shell, left side cover, right side cover, rear cover, and base for covering the main body 4; a module compartment 8 for facilitating the assembly of the emission net and collection net; light strips and light panels for displaying the working status; a screen bracket for mounting the display screen and a lens for easy observation of the display screen; and rollers installed on the lower edge of the base for machine movement.

[0032] Furthermore, the TVOC sensor inside the ion air purifier is equipped with a silicone protective cover. The silicone protective cover can prevent the bare TVOC sensor board from being easily damaged by static electricity, greatly extending the life of the sensor.

[0033] The above is a description of the technical solution of this utility model, which is used to help understand this utility model; however, the implementation of this utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of this utility model shall be considered as equivalent substitutions and shall be included within the protection scope of this utility model.
