In the description of the present invention, "a plurality" means two or more.

An electrostatic precipitator 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1-5, the electrostatic precipitator 1 according to the embodiment of the present invention includes a plurality of electrode units 100, the plurality of electrode units 100 at least includes a high potential unit 130 and a low potential unit 140, the plurality of electrode units 100 are disposed at intervals, and the high potential unit 130 and the low potential unit 140 are alternately arranged, in other words, some electrode units 100 can be used as the high potential unit 130, some electrode units 100 can be used as the low potential unit 140, that is, the electrode unit 100 adjacent to the high potential unit 130 is the low potential unit 140, and the electrode unit 100 adjacent to the low potential unit 140 is the high potential unit, for example, the arrangement manner of the plurality of electrode units 100 is: the high potential units 130, the low potential units 140, the high potential units 130, and the low potential units 140 are alternately arranged in sequence. A dust removal air duct is formed between the adjacent electrode units 100.

Each electrode unit 100 is annular and includes a conductive portion 110 and an insulating portion 120, the conductive portion 110 includes a conductive protrusion 111 and an electric field generator 112, the insulating portion 120 covers a portion of the electric field generator 112, and the dust removal duct extends annularly along the circumferential direction of the adjacent high potential unit 130 and the low potential unit 140.

It is understood that the conductive protrusion 111 refers to a portion of the conductive portion 110 for achieving electrical conduction. The electric field generator 112 is a portion of the conductive portion 110 for generating an electric field.

According to the electrostatic precipitator 1 of the embodiment of the present invention, the insulating part 120 is used to cover the electric field generating body 112, so that the electric field generating bodies 112 of the adjacent electrode units 100 are separated by the insulating part 120, on one hand, corona discharge between the electrode units 100 is avoided, and ozone generation due to breakdown is avoided, thereby solving the problem of ozone disturbance and reducing the risk of electric shock accidents from the source of ozone generation, thereby greatly improving the safety of use, on the other hand, the covering method can form the conductive part 110 and the insulating part 120 into a whole, which is beneficial to simplifying assembly, and each electrode unit 100 forms an independent whole, thus, in production or use, each electrode unit 100 can be independently replaced, for example, if some electrode unit 100 is found to have a defect in production, it can be independently replaced, and a plurality of electrode units 100 or the whole dust removing device 1 does not need to be processed, so that the yield of products is indirectly improved, the production cost is saved, and in the using process, the maintenance and the repair in the using process are facilitated as the single electrode unit 100 can be replaced.

Because a high-voltage electric field can be generated between the adjacent electrode units 100 of the electrostatic dust collector 1, air molecules can be ionized into positive ions and negative ions through the high-voltage electric field, when the negative ions are in contact with bacteria, molds, viruses and the like, the negative ions carry redundant electrons, molecular protein structures in the bacteria, the molds, the viruses and the like can be damaged, structural change (two polarities of proteins are reversed) or energy transfer is generated on the bacteria, the molds, the viruses and the like, and therefore microorganisms such as bacteria, viruses and the like can die. Therefore, the electrostatic precipitator 1 has a sterilization effect, and the cleanliness of air is improved.

By configuring each electrode unit 100 as an annular shape, air can enter the electrostatic dust collector 1 from each angle in the circumferential direction of the electrostatic dust collector 1, and the air can be fully contacted with the electrode unit 100, so that the air inlet efficiency of the electrostatic dust collector 1 is improved, and the dust collection effect of the electrostatic dust collector 1 is good. Moreover, each electrode unit 100 is annular, so when the dust removal area of the electrode unit 100 is increased, the electrode units 100 can extend all around simultaneously, so that the occupied space of the electrostatic dust removal device 1 is small while the dust removal area is ensured.

Therefore, according to the utility model discloses electrostatic precipitator 1 has compromise dust removal sterilization area and space utilization, and can realize that full angle dust removal disinfects in its circumference, has the dust removal effect and disinfects advantages such as good and the security is high.

According to some embodiments of the present invention, as shown in fig. 4 and 5, the insulating part 120 covers the whole electric field generator 112, so that the probability of discharge between adjacent electrode units 100 is lower, the probability of ozone generation is further reduced, the risk of electric shock is reduced, and the reliability of the electrostatic dust collector 1 is greatly improved.

According to some embodiments of the present invention, as shown in fig. 1 to 3, the electrode units 100 are arranged along an axial direction of the plurality of electrode units 100. Therefore, the wind resistance can be reduced, the dust collecting and sterilizing area can be increased, and the occupied space of the electrostatic dust collector 1 is smaller.

According to some embodiments of the present invention, as shown in fig. 4 and 5, the conductive part 110 and the insulating part 120 of the plurality of electrode units 100 are injection molded. Thus, the conductive part 110 and the insulating part 120 form a complete whole, which not only simplifies the assembly and has more stable structure, but also can utilize the mold to ensure that the thickness of the electrode unit 100 is uniform and controllable, and is beneficial to mass production and space consistency, so that the wind resistance of all parts of the electrostatic dust collector 1 is consistent, and the dust collection uniformity can be improved.

Further, the conductive parts 110 and the insulating parts 120 of the plurality of electrode units 100 are integrally injection molded. Thus, the electrostatic precipitator 1 is more efficient in production.

According to some embodiments of the present invention, as shown in fig. 4 and 5, the conductive portion 110 is a conductive plastic member. Therefore, each electrode unit 100 is easy to form into a ring shape, the processing is simple, and the mass production is facilitated. Moreover, the conductive plastic part has light weight, good stretchability, elasticity and flexibility and is convenient to form, and meanwhile, the conductive plastic part has the advantages of metal, such as good conductivity.

According to some embodiments of the present invention, as shown in fig. 4 and 5, the electrode unit 100 has a circular ring shape.

It can be understood that the circular electrode unit 100 is more space-saving after being stacked compared with the non-circular electrode unit 100, and the occupied space of the electrostatic dust collector 1 can be further reduced while the dust-collecting area and the sterilization effect are considered. Moreover, since the outer diameters of the circular electrode units 100 in the radial direction are the same, when the plurality of electrode units 100 are installed, the circumferential alignment is not required, and the lengths of the electrode units 100 in the radial direction are not completely the same, so that when the plurality of electrode units 100 are installed, the circumferential alignment is required, that is, the circular electrode units 100 are more convenient to install.

According to some embodiments of the present invention, as shown in fig. 4 and 5, one of the adjacent electrode units 100 is provided with a positioning ring 150, and the other is provided with a positioning protrusion 160 inserted into the positioning ring 150.

For example, the positioning rings 150 are formed around the groove portions, and the positioning rings 150 are arranged in the circumferential direction of the electrode unit 100. The adjacent electrode units 100 are matched and assembled with the positioning ring 150 through the positioning protrusions 160, so that a plurality of electrode units 100 can be fixed together to form a whole, and due to the arrangement of the positioning protrusions 160 and the positioning ring 150, the distance between the adjacent electrode units 100 can be reliably limited, and the consistency of the dust removal air channel is ensured.

In addition, the positioning ring 150 is disposed on one side of the electrode unit 100 in the thickness direction, the positioning protrusion 160 is disposed on the other side of the electrode unit 100 in the thickness direction, and the positioning ring 150 and the positioning protrusion 160 are disposed on the insulating portion 120 of the electrode unit 100, so that corona discharge of the electrostatic dust collector 1 can be further prevented, the probability of ozone generation and electric shock is reduced, and the processing and assembly are facilitated, and the assembly efficiency is improved.

This ensures that the high potential units 21 are electrically conductive and have the same potential, and also ensures that the low potential units 22 are electrically conductive and have the same potential.

It is to be understood that the first conductive bumps and the second insulating bumps are alternately arranged, for example, the first conductive bumps, the second insulating bumps, the first conductive bumps, and the second insulating bumps are alternately stacked at intervals. The second conductive bumps and the first insulating bumps are alternately arranged, for example, the second conductive bumps, the first insulating bumps, the second conductive bumps, and the first insulating bumps are alternately stacked at intervals. This ensures that the high potential units 130 and the low potential units 140 are alternately arranged, thereby ensuring that the electrostatic precipitator 1 can generate an electric field to remove dust and sterilize the use site.

Since the insulating part 120 entirely covers the electric field generator 112 of the conductive part 110, the thickness of the electric field generator 112 is smaller than that of the insulating part 120, and the thickness of the conductive protrusion 111 can be set to be the same as that of the electric field generator 112, which facilitates the production and processing of the conductive part 110 and takes into account the production cost and the structural strength. And the first and second insulating protrusions are formed of the insulating part 120, so the thickness of the first and second insulating protrusions may be greater than the thickness of the first and second conductive protrusions. Thus, the connection strength between the plurality of potential units 23 and the first positioning piece 200 and the second positioning piece 300 is ensured, and the overall structural stability of the electrostatic dust collector 1 is improved. In addition, the width of the low potential slot is larger than that of the high potential slot, so that the distance between the high potential unit 130 and the low potential unit 140 in the thickness direction of the electrode unit 100 can be ensured to be fixed, and the corresponding relation between the insulating protrusion 121 and the conductive protrusion 111 and the high potential slot and the low potential slot can be conveniently distinguished during assembly, thereby reducing the assembly difficulty and improving the assembly speed.

the first cover plate 600 may be provided with the air guiding opening 630, and the first cover plate 600 may not be provided with the air guiding opening 630. When the electrostatic dust collector 1 is applied, the high-potential conductive contact piece 640 and the low-potential conductive contact piece 650 can be connected with a power supply, so that the electrostatic dust collector 1 is convenient to electrically connect, and because the contact type electric connection between the electrostatic dust collector 1 and the power supply can be realized through the contact pieces, a wire can be omitted, and the assembly difficulty is reduced.

Further, a mounting groove 740 is provided on a side of the first cover plate 600 facing away from the plurality of electrode units 100, and the high potential conductive contact piece 640 and the low potential conductive contact piece 650 are located in the mounting groove 740.

Thus, the production efficiency is high. In other embodiments of the present invention, the high potential conductive contact 640 and the low potential conductive contact 650 are integrally injection-molded with the first cover 600. Thus, the production efficiency is higher.

In addition, the first cover plate 600 is provided with a wire through hole (not shown), through which a wire between the high potential conductive contact 640 and the high potential conductive member 230 passes, and through which a wire between the low potential conductive contact 650 and the low potential conductive member 330 passes.

Each handle 910 is configured as a portion of a ring, such that each handle 910 is evenly stressed, increasing the useful life of the handle 910. The shape of the receiving groove 750 may be adapted to the shape of the handle 910, for example, the handle 910 may be a ring-shaped portion, the receiving groove 750 may be an annular groove extending around the circumference of the first cover 600, and the annular groove may be provided on the outer circumferential side of the first cover 600.

When the handle 910 is in the operating state, the handle 910 is located outside the accommodating groove 750, and at this time, the handle 910 can be held, so that not only the overall movement of the electrostatic dust removal device 1 is facilitated, but also the cleaning of the electrostatic dust removal device 1 is facilitated.

According to some embodiments of the present invention, as shown in fig. 1, the electrostatic precipitator 1 further includes a first fixing member 800 and a second fixing member (not shown). The first fixing member 800 includes a stopping portion 810 and a pillar portion 820, one end of the pillar portion 820 is connected with the stopping portion 810, the stopping portion 810 abuts against a surface of the first cover plate 600 facing away from the electrode unit 100, the pillar portion 820 sequentially penetrates through the first cover plate 600, the plurality of electrode units 100 and the second cover plate 700 along the axial direction of the electrode unit 100, and the second fixing member is disposed on the second cover plate 700 and is matched with the other end of the pillar portion 820.

For example, the other end of the pillar 820 may be provided with an external thread, the second fixing member may be provided on a surface of the second cover plate 700 facing away from the electrode unit 100, the second fixing member may be a nut, and the nut is provided with an internal thread matching with the external thread; or, the other end of the column part 820 is provided with a through hole, and the second fixing part is a plug which extends into the through hole.

This ensures that the stopping portion 810 is lower than the surface of the first cover plate 600 and the second fixing member is lower than the surface of the second cover plate 700, which not only improves the tidiness of the electrostatic dust collector 1, but also prevents the stopping portion 810 and the second fixing member from being worn or scratching other parts.

According to some embodiments of the present invention, as shown in fig. 1, the post 820 passes through the positioning ring 150 and the positioning protrusion 160 of each electrode unit 100. It will be appreciated that each post 820 passes through one locating ring 150 and one locating projection 160 of each electrode unit 100. This reduces the number of steps of the manufacturing process and improves the stability of the connection between the adjacent electrode units 100.

For example, if the positioning protrusion 160 is provided on the side of the electrode unit 100, which is closest to the first cover plate 600, of the plurality of electrode units 100 facing the first cover plate 600, the positioning structure 770 of the first cover plate 600 may be the same as the positioning ring 150, and the positioning ring 150 is provided on the side of the electrode unit 100, which is closest to the second cover plate 700, of the plurality of electrode units 100 facing the second cover plate 700, and the positioning structure 770 of the second cover plate 700 may be the same as the positioning protrusion 160.

Still further, the first fixing pieces 800 are a plurality of fixing pieces arranged at intervals along the circumferential direction of the electrode unit 100, the second fixing pieces are a plurality of fixing pieces arranged at intervals along the circumferential direction of the electrode unit 100, and the first fixing pieces 800 and the second fixing pieces are matched in a one-to-one correspondence manner. The number of the first fixing members 800 is equal to the number of the second fixing members, and the number of the first fixing members 800 is less than or equal to the number of the positioning rings 150 or the positioning protrusions 160 of each electrode unit 100.

For example, the plurality of first fixing pieces 800 and the plurality of second fixing pieces may be respectively disposed at regular intervals in the circumferential direction of the electrode unit 100. The stability of the relative positions between the first cover plate 600, the second cover plate 700, and the plurality of electrode units is further increased, thereby improving the structural strength of the electrostatic precipitator 1.
