[0007] The charged module includes a hollow shell, and a charged element is disposed inside the shell. Through holes are provided on both sides of the shell along the air flow direction at positions corresponding to the charged element. The charged module is connected to a negative high-voltage power supply to form a negative high-voltage electric field. The outer shell is connected to a ground wire, and the charged element is connected to a negative high-voltage power supply.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

The terms "first," "second," "third," "fourth," etc. (if present), in the specification, claims, and accompanying drawings of this utility model are intended to distinguish the objects they refer to. For solutions with a sequential flow, this terminology need not be interpreted as describing a specific order or sequence; for solutions with device structures, this terminology does not distinguish between matters of importance or positional relationships.

[0026] Furthermore, the terms “comprising,” “having,” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may also include other steps or units that are not expressly listed but are inherent to these processes, methods, products, or devices, or steps or units added based on further optimizations of the inventive concept.

[0027] like Figures 1-4 As shown, this utility model discloses an integrated electrostatic field purification device, which includes a charged module 1 and a dust collection module 2, wherein the charged module 1 and the dust collection module 2 are installed sequentially in the purification device along the air flow direction.

[0028] The charged module 1 includes a hollow shell, and a charged element is disposed inside the shell. Through holes 15 are provided on both sides of the shell along the air flow direction at positions corresponding to the charged element. The charged module 1 is connected to a negative high-voltage power supply to form a negative high-voltage electric field. The shell is connected to a ground wire and a reference voltage (or common reference point) is used. The charged element is connected to the negative high-voltage power supply to realize needle tip discharge.

[0029] The dust collection module 2 includes an annular frame 21, and a mesh dust collection plate 22 is provided inside the annular frame 21. The dust collection plate 22 is fixedly connected to the frame 21, and the dust collection module 2 is connected to a positive high voltage power supply to form a positive high voltage electric field.

[0030] The aforementioned charged module 1 and dust collection module 2 are installed inside the purification device. The purification device can be an existing purification device. The charged module 1 and dust collection module 2 are installed inside the purification device along the air flow direction of the purification device, and the air flowing along the air inlet and air outlet flows through the charged module 1 and dust collection module 2 in sequence. The air enters the device from the air inlet, is purified by the charged module 1 and dust collection module 2, and is discharged from the air outlet.

[0031] The charged element includes a vertically arranged support plate 13, which is fixedly connected to the housing. Multiple support plates 13 are evenly spaced along the length of the housing, and multiple steel needles 14 are evenly spaced on both sides of each support plate 13. Multiple through holes 15 are provided, with each through hole 15 corresponding to one steel needle 14. Both the support plate 13 and the steel needles 14 are made of stainless steel and are integrally formed.

[0032] The charging module 1 uses stainless steel needles 14 as charging elements. Stainless steel needles 14 have good conductivity and corrosion resistance, ensuring long-term stable operation. The charging module 1 is connected to a negative high-voltage power supply, forming a negative high-voltage electric field, with the shell serving as the negative electrode and the steel needles 14 as the positive electrode. When air passes through the charging module 1, the airborne particles are ionized and acquire a negative charge under the influence of the negative high-voltage electric field. Specifically, the stainless steel needles 14 are arranged in an array on the frame 21 of the charging module 1. This distribution allows air to pass evenly through the charging region, improving the charging effect on the particles.

[0033] In a further specific embodiment, the housing includes a lower housing 12 and an upper housing 11. Both the lower housing 12 and the upper housing 11 are groove-shaped structures. The inner wall size of the groove of the upper housing 11 is adapted to the outer wall size of the lower housing 12 so that the upper housing 11 and the lower housing 12 are fastened together. The upper housing 11 and the lower housing 12 are fixedly connected by bolts.

[0034] The housing is configured as a detachable upper housing 11 and a lower housing 12. Both the upper housing 11 and the lower housing 12 are groove-shaped structures. The groove of the lower housing 12 is used to install charged elements. The upper housing 11 can be snapped together and fixed to the top of the lower housing 12.

[0035] The charged element includes a stainless steel support plate 13 and a stainless steel needle 14. The support plate 13 can be fixed to the lower housing 12 by bolts. The support plate 13 is installed between two adjacent rows of through holes 15. The support plate 13 extends towards the center of the through holes 15 on both sides to form a support rod. The end of the support rod extends axially towards the through hole 15 to form a steel needle 14. The support plate 13, the support rod and the steel needle 14 are integrally formed.

[0036] In a further embodiment, the mesh of the dust collection plate 22 is quadrilateral or hexagonal.

[0037] The dust collection plate 22 is made of dielectric material and has electrode sheets wrapped with conductive ink material inside.

[0038] The aforementioned dust collection plate 22 adopts a honeycomb structure. The honeycomb dust collection plate 22 is made of dielectric material and internally encapsulates electrode sheets made of conductive ink material. The dust collection module 2 is connected to a positive high-voltage power supply, forming a positive high-voltage electric field. When negatively charged particles enter the dust collection module 2 with the air, they are adsorbed onto the honeycomb dust collection plate 22 under the action of the positive high-voltage electric field, thereby achieving particle collection. The honeycomb structure greatly increases the dust collection area and improves dust collection efficiency. Simultaneously, the use of dielectric material can create a strong and stable electric field within the channel, enhancing the adsorption capacity for charged particles.

[0039] In another embodiment, an electric field control module can be provided to ensure the stability of the electric field and the purification effect. The electric field control module can monitor the electric field strength of the charging module 1 and the dust collection module 2 in real time, and automatically adjust the output of the negative high voltage and positive high voltage according to the actual situation to ensure that the electric field strength is always in the optimal working state. In addition, the electric field control module also has overvoltage and overcurrent protection functions; when an abnormality occurs in the electric field, it can promptly cut off the power supply to protect the device's safety.

[0040] For ease of cleaning and maintenance, the charging module 1 and dust collection module 2 can be detachably connected to the purification device. Users can easily open the outer casing of the purification device and remove the charging module 1 and dust collection module 2 for cleaning. The stainless steel needles 14 of the charging module 1 are relatively easy to clean due to their smooth surface; the honeycomb dust collection plate 22 of the dust collection module 2 can be cleaned by washing or wiping to restore its dust collection performance.

[0041] The beneficial effects of this invention are as follows: The use of stainless steel needles 14 as charging elements and the honeycomb dust collection plate 22 structure significantly improves air purification efficiency. The excellent conductivity and corrosion resistance of the stainless steel needles 14 ensure the stability of the charging effect, while the honeycomb dust collection plate 22 increases the dust collection area, enabling more effective collection of airborne particles. Real-time monitoring and adjustment of the electric field strength via the electric field control module ensures the device always operates in optimal condition, improving particle collection efficiency. The detachable design of the charging module 1 and dust collection module 2 facilitates easy cleaning, reducing maintenance costs and operational difficulties for users, and extending the device's service life.

[0042] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0043] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0044] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments.
