[0001] Related art cross-reference

[0002] This application claims priority to the Chinese patent publication entitled "Electrostatic air cleaner" with publication number 202410653242.4, filed on May 24, 2024, with the China National Intellectual Property Office, the entire contents of which are incorporated by reference into the present disclosure. TECHNICAL FIELD

[0003] The present disclosure relates to the field of air purification equipment, in particular to an electrostatic air cleaner. BACKGROUND

[0004] The core components of the electrostatic air cleaner are the electrostatic generating device and the particulate matter collecting device. Among them, the role of the electrostatic generating device is to ionize the air by high voltage, so that the particulate matter in the air is charged positively, and the particulate matter collecting device is usually connected to a negative high voltage, so that a negative high voltage field is formed inside the particulate matter collecting device. When the particulate matter with positive charge flows through the negative high voltage field with the air, the particulate matter is adsorbed in the collecting device, thereby achieving the effect of purifying the air.

[0005] Generally, the electrostatic generating device needs to be connected to a positive direct current high voltage of 10-20kv, and the particulate matter collecting device usually needs to be connected to a negative direct current high voltage of 2-10kv. Due to the working nature of the electrostatic air cleaner, after working for a period of time, the electrostatic generating device and the collecting device need to be disassembled and cleaned and maintained or replaced due to the accumulation of particulate matter collection. Therefore, the high voltage connection of the generating device and the collecting device needs to be designed into a structure that can be disassembled and cleaned and maintained.

[0006] The electrostatic generating device and the dust collecting device usually need to be installed and disassembled through a quick connection type wiring structure. The commonly used wiring structure in the industry is the contact type of spring (or spring) and spring (or spring) and the contact type of pin and spring. When the above two connection methods are used, the wiring structure cannot be sealed, and under the action of high voltage electricity of several thousand volts to several tens of thousands of volts, there is often leakage at sharp parts, and electric sparks are formed on the surface of the fixed shell. In severe cases, high voltage breakdown occurs, leading to short circuit.

Detailed Implementation

[0051] The following detailed embodiments are provided to aid the reader in gaining a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent upon understanding the disclosure herein. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent upon understanding the disclosure herein may be made, except for operations that must occur in a specific order. Furthermore, descriptions of features known in the art may be omitted for clarity and brevity.

[0052] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent upon understanding the disclosure herein.

[0053] Throughout the specification, when an element (such as a layer, region or substrate) is referred to as being "on" another element, "connected to" another element, "coupled to" another element, "adjacent to" another element, "on top of" another element or "covering" another element, it can be directly on, connected to, coupled to, adjacent to, on top of, or covering the other element, or one or more other elements can be interposed therebetween. In contrast, when an element is referred to as being "directly on", "directly connected to", "directly coupled to", "directly adjacent to", "directly on top of", or "directly covering" another element, there are no other elements interposed therebetween.

[0054] As used herein, the term "and / or" includes any one of the listed items and any combination of two or more of the listed items.

[0055] Although terms such as "first" and "second" and "third" can be used herein to describe various components, assemblies, regions, layers or sections, these components, assemblies, regions, layers or sections are not limited by these terms. Rather, these terms are only used to distinguish one component, assembly, region, layer or section from another component, assembly, region, layer or section. Thus, the first component, assembly, region, layer or section described in the examples described herein could also be termed a second component, assembly, region, layer or section, without departing from the teachings of the examples.

[0056] For ease of description, spatial relationship terms, such as "on", "upper", "beneath", and "lower", can be used herein to describe the relationship of one element to another element as illustrated in the figures. Such spatial relationship terms can be intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, a element described as on "upper" or "top" of another element would then be oriented on a "lower" or "bottom" of the other element. Thus, the term "on" can encompass both an "on" and "under" orientation depending on the spatial orientation of the device. The device can be oriented in other ways (e.g., rotated 90 degrees or at other orientations) and an appropriate modification to the spatial relationship terminology will be made accordingly.

[0057] The terminology used herein is for the purpose of describing various examples only and is not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "includes," "including" and "has" are listed means the stated features, numbers, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, numbers, operations, components, elements, and / or combinations thereof.

[0059] Features of the examples described herein can be combined with one another in any manner, as will be apparent after understanding the disclosure provided herein. Moreover, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure provided herein.

In the electrostatic air cleaner of the present disclosure, three fixing holes are formed on the housing 1. The high-voltage circuit control module 2 is connected with the electrostatic generation module 3 and the collection module 4 in the interior of the housing 1 through the three conductive assemblies 6. The insulating sleeve 91 is sleeved on the conductive assembly 6, and the insulating sleeve 91 abuts against the hole wall of the fixing hole, thereby achieving the insulation of the housing 1 and the conductive assembly 6. In this way, the electric spark pattern of the housing 1 caused by the electric leakage of the conductive assembly 6 is avoided, and the short circuit problem caused by the high-voltage breakdown of the housing 1 is avoided.

[0061] In addition, the conductive assembly 6 extends into the interior of the housing 1 and is connected with the electrostatic generation module 3 and the collection module 4, thereby avoiding the rusting and aging problem caused by the exposure of the conductive assembly 6.

[0062] In the embodiment of the present disclosure, as shown in FIG. 2, the shell 1 comprises a first fixed plate 11, a second fixed plate 12, a third fixed plate 13 and a fourth fixed plate 14, the first fixed plate 11 is parallel to the second fixed plate 12, and the third fixed plate 13 and the fourth fixed plate 14 are parallel. The first fixed plate 11, the third fixed plate 13, the second fixed plate 12 and the fourth fixed plate 14 are sequentially connected, the high-voltage circuit control module 2 is fixed on the outer side wall of the first fixed plate 11 facing away from the second fixed plate 12, and the three conductive assemblies 6 penetrate through the first fixed plate 11 to extend into the interior of the shell 1, so as to be connected with the static electricity generating module 3 and the collecting module 4. An opening 121 is formed on the second fixed plate 12, so that the static electricity generating module 3 and the collecting module 4 can be fixed to the interior of the shell 1 through the opening 121. A door body is arranged on the opening 121, and the door body is detachably connected with the opening 121. The side of the third fixed plate 13 facing the fourth fixed plate 14 is provided with a first fixed strip 15, a second fixed strip 16 and a third fixed strip 17, and the side of the fourth fixed plate 14 facing the third fixed plate 13 is also provided with a first fixed strip 15, a second fixed strip 16 and a third fixed strip 17. When installing the static electricity generating module 3, the lower end of the static electricity generating module 3 is abutted against the two first fixed strips 15, the upper end of the static electricity generating module 3 is abutted against the two second fixed strips 16, and then the static electricity generating module 3 is pushed to slide until the static electricity generating module 3 is connected with one conductive assembly 6, so as to realize the fixation of the static electricity generating module 3. When installing the collecting module 4, the lower end of the collecting module 4 is abutted against the two second fixed strips 16, the upper end of the collecting module 4 is abutted against the two third fixed strips 17, and then the collecting module 4 is pushed to slide until the collecting module 4 is connected with the two conductive assemblies 6, so as to realize the fixation of the collecting module 4. In this way, the static electricity generating module and the collecting module 4 can be connected with the conductive needle 61 by pushing the static electricity generating module 3 and the collecting module 4, thereby improving the convenience of installation of the static electricity generating module 3 and the collecting module 4.

[0063] Further, the bottom of the shell 1 has an air inlet, the top of the shell 1 has an air outlet, and the top of the shell 1 is provided with a fan 5. The static electricity type air purifier is generally installed through a support frame, so that the bottom of the static electricity type air purifier is suspended. Under the driving of the fan 5, air flows into the interior of the shell 1 from the air inlet at the bottom, and when passing through the high-voltage electric field formed by the static electricity generating module 3, the particulate matters are positively charged. When passing through the negative electric field formed by the collecting device, the particulate matters are adsorbed into the interior of the collecting device, and then the air flows out from the air outlet, thereby forming the air purification effect.

[0064] As shown in FIG. 14, the high-voltage circuit control module 2 includes a positive direct-current high-voltage output end 21, a negative direct-current high-voltage output end 22, and a ground output end 23, which are respectively connected with three conductive pins 61. The conductive pin 61 connected with the positive direct-current high-voltage output end 21 is connected with the static electricity generation module 3, and the conductive pin 61 connected with the negative direct-current high-voltage output end 22 and the conductive pin 61 connected with the ground output end 23 are connected with the collection module 4.

[0065] In the embodiments of the present disclosure, as shown in FIGS. 12-17, the conductive assembly 6 includes the conductive pin 61, a connecting piece, and a glue covering part 63. The end of the conductive pin 61 is provided with a thread, one end of the connecting piece is connected with the high-voltage circuit control module 2 through a cable 62, and the other end of the connecting piece is provided with a threaded counterbore, so as to facilitate the connection of the terminal post with the conductive pin 61. The connecting piece and the cable 62 can be glued and injection molded together, and the glue covering part 63 is formed after the glue is cured. By providing the glue covering part 63, the discharge phenomenon of the sharp part on the conductive pin 61 under high voltage can be avoided, and the insulation and reliability of the conductive pin 61 can be greatly improved, thereby preventing the problem of high-voltage static electricity leakage and creeping.

[0066] Preferably, the glue covering part 63 can be made of PVC (Polyvinyl chloride) or Teflon through glue injection molding. The glue covering part 63 formed in this way has good waterproof and dustproof effects.

[0067] As shown in FIG. 17, the connecting piece can include a first hole and a second hole. The first hole and the second hole are respectively recessed from the two surfaces of the connecting piece opposite to each other to the inside of the connecting piece. The hole wall of the first hole is provided with a thread, so as to realize the connection of the connecting piece with the conductive pin 61. The connecting piece is threadedly connected with the conductive pin 61, which can facilitate the replacement of the conductive pin 61. The cable 62 is inserted into the second hole, so as to realize the connection of the cable 62 with the connecting piece. The glue covering part 63 covers the entire connecting piece and part of the conductive pin 61. An insulating sleeve 91 is sleeved outside the glue covering part 63, and part of the conductive pin 61 is also covered outside the insulating sleeve 91. Through the cooperation of the insulating sleeve 91 and the glue covering part 63, the conductive pin 61 is not exposed except for the part used to connect with the connecting piece 8 described below, thereby further improving the insulation of the conductive pin 61.

[0068] In addition, the cable 62 is sleeved with a heat shrinkable sleeve 65. The heat shrinkable sleeve 65 is sleeved outside the cable 62. Part of the heat shrinkable sleeve 65 is located inside the glue covering part 63, and the other part of the heat shrinkable sleeve 65 is exposed outside the glue covering part 63. The heat shrinkable sleeve 65 realizes the insulation of the cable 62. The adhesion between the heat shrinkable sleeve 65 and the glue covering part 63 is higher, which can avoid the gap between the glue covering part 63 and the cable 62, thereby improving the insulation of the connection between the cable 62 and the connecting piece.

[0069] Further, the three cables 62 are connected with the positive direct current high voltage output end 21, the negative direct current high voltage output end 22 and the ground output end 23 respectively, so as to realize the connection of the three conductive needles 61 with the positive direct current high voltage output end 21, the negative direct current high voltage output end 22 and the ground output end 23.

The axis of the limiting cavity coincides with the axis of the conductive assembly 6. By arranging the mounting piece 18, the installation precision of the conductive assembly 6 can be improved. At the same time, by arranging the fixed cover 64, the conductive assembly 6 is completely sealed in the mounting piece 18, which can effectively prevent the occurrence of the phenomena of electric leakage, electric discharge and electric creep of the conductive needle 61 to the first fixed plate 11, and improve the stability of the operation of the electrostatic air purifier.

[0071] In the embodiment of the present disclosure, as shown in FIG. 3, the electrostatic air purifier further comprises an insulating pad 7. One side of the insulating pad 7 is attached to the inner side wall of the first fixed plate 11, and the other side of the insulating pad 7 is attached to the electrostatic generation module 3 and the collection module 4 respectively. The three conductive assemblies 6 all pass through the insulating pad 7, so as to facilitate the connection of the three conductive assemblies 6 with the electrostatic generation module 3 and the collection module 4. By insulating the part between the first fixed plate 11 and the electrostatic generation module 3 and the part between the first fixed plate 11 and the collection module 4 of the conductive assembly 6 through the insulating pad 7, the outflow of high-voltage static electricity and the occurrence of electric creep during the operation of the electrostatic air purifier can be effectively prevented.

[0072] Further, the collection module 4 comprises a collection assembly and a grounding assembly. The electrostatic air purifier further comprises three connecting pieces 8. The collection assembly, the grounding assembly and the electrostatic generation module 3 are connected with the three conductive assemblies 6 through the three connecting pieces 8 respectively. The three connecting pieces 8 are all located on the side of the insulating pad 7 which is away from the shell 1. The three connecting pieces 8 can be separated from the first fixed plate 11 through the insulating pad 7, so as to avoid the outflow of high-voltage static electricity.

[0073] Optionally, the insulating pad 7 comprises a main body part 71, a first partition part 72, a second partition part 73 and a third partition part 74, the main body part 71 is plate-shaped, the first partition part 72, the second partition part 73 and the third partition part 74 are block-shaped, the first partition part 72 and the second partition part 73 are connected with two ends of the main body part 71 respectively, and the third partition part 74 is connected with the middle part of the main body part 71. When the static electricity generating module 3 and the collecting module 4 are connected with the three conductive pins 61 respectively, the static electricity generating module 3 is located between the first partition part 72 and the third partition part 74, and the collecting module 4 is located between the second partition part 73 and the third partition part 74.
