DETAILED DESCRIPTION

[0036] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0037] See also Figure 1 to Figure 4 The sheet material for electrostatic dust removal filter shown in the figure includes a substrate 1, a plurality of first conductive layers 2 arranged on the substrate 1 at intervals along the length direction of the substrate 1, and a plurality of second conductive layers 3 arranged on the substrate 1 at intervals along the length direction of the substrate 1. The first conductive layers 2 and the second conductive layers 3 are alternately distributed so that one second conductive layer 3 is distributed between two adjacent first conductive layers 2 and one first conductive layer 2 is distributed between two adjacent second conductive layers 3.

[0038] The sheet also includes a first conductive tape 4 arranged on the substrate 1 and electrically connected to each first conductive layer 2, and a second conductive tape 5 arranged on the substrate 1 and electrically connected to each second conductive layer 3. The first conductive tape 4 is used to be electrically connected to the high-voltage negative electrode, and the second conductive tape 5 is used to be electrically connected to the high-voltage positive electrode.

[0039] A plurality of through holes 10 are arranged at intervals along the width direction of the substrate 1 between the adjacent first conductive layer 2 and the second conductive layer 3, so that after the sheet is folded, the through holes 10 serve as ventilation holes for air flow.

[0040] All first conductive layers 2 and first conductive tapes 4 are integrally printed, and all second conductive layers 3 and second conductive tapes 5 are integrally printed, so that after the sheet is folded, when high voltage is energized, it is only necessary to electrically connect the high voltage negative electrode to the first conductive tape 4 and the high voltage positive electrode to the second conductive tape 5, so that all first conductive layers 2 and all second conductive layers 3 can be energized, without setting a conductive part to electrically connect each first conductive layer or each second conductive layer, thereby greatly simplifying the process operation of electrostatic dust removal filter element production.

[0041] All first conductive layers 2, first conductive strips 4, all second conductive layers 3 and second conductive strips 5 can be obtained by printing with conductive ink, see Figure 4 The substrate 1 includes a first insulating layer 1a and a second insulating layer 1b stacked in sequence, and all first conductive layers 2, first conductive tapes 4, and all second conductive layers 3 and second conductive tapes 5 are arranged between the first insulating layer 1a and the second insulating layer 1b, so that the first conductive layer 2, the first conductive tape 4, the second conductive layer 3 and the second conductive tape 5 are insulated from the outside world, and the safety is high. The material of the first insulating layer 1a and the second insulating layer 1b can be polytetrafluoroethylene, polyperfluoroethylene propylene, polypropylene or polyethylene. In the specific preparation, the first conductive layer 2, the first conductive tape 4, the second conductive layer 3 and the second conductive tape 5 are printed on the first insulating layer 1a, and then the second insulating layer 1b is attached, and the first conductive layer 2, the first conductive tape 4, the second conductive layer 3 and the second conductive tape 5 are encapsulated between the first insulating layer 1a and the second insulating layer 1b.

[0042] The first conductive tape 4 and the second conductive tape 5 are respectively located on opposite sides of the substrate 1. Specifically, a first safety distance is formed between one end of each first conductive layer 2 and one side edge of the substrate 1, and a second safety distance is formed between one end of each second conductive layer 3 and the other side edge of the substrate 1. The first conductive tape 4 passes through the second safety distance, and the second conductive tape 5 passes through the first safety distance, which facilitates the wiring of the first conductive tape 4 and the second conductive tape 5.

[0043] The first fold 6 and the second fold 7 are arranged at intervals on the substrate 1 between the adjacent first conductive layers 2 and the second conductive layers 3, and the first fold 6 and the second fold 7 extend along the width direction of the substrate 1, respectively. Part of the first fold 6 and the second fold 7 are located on the substrate 1 between two adjacent through holes 10, respectively. The arrangement of the first fold 6 and the second fold 7 facilitates the folding of the sheet. When the sheet is folded, it is folded along the first fold 6 and the second fold 7. The distance between the first fold 6 and the second fold 7 is the distance between the part of the substrate where the first conductive layer 2 is located and the part of the substrate where the second conductive layer 3 is located after folding, and is also the distance of the dust collecting space between the first conductive layer 2 and the second conductive layer 3 formed after folding, which facilitates the circulation of airflow. The part of the substrate between the first fold 6 and the second fold 7 after folding serves as a support portion.

[0044] In order to make the folded sheet have a certain strength for easy installation, a clamping piece 8 and a clamping slot 9 that can cooperate with the clamping piece 8 are punched on the base material 1, and the clamping piece 8 is inserted into the clamping slot 9 after the folded sheet.

[0045] Specifically, each first conductive layer 2 includes a plurality of first conductive units 2a spaced apart along the width direction of the substrate 1, and a first conductive connecting strip 2b is respectively connected between two adjacent first conductive units 2a in each first conductive layer 2 and between the first conductive unit 2a close to the first conductive tape 4 and the first conductive tape 4; each second conductive layer 3 includes a plurality of second conductive units 3a spaced apart along the width direction of the substrate 1, and a second conductive connecting strip 3b is respectively connected between two adjacent second conductive units 3a in each second conductive unit 3a and between the second conductive unit 3a close to the second conductive tape 5 and the second conductive tape 5.

[0046] A clamping piece 8 is provided on the substrate 1 between two adjacent first conductive units 2a and located on one side of the first conductive connecting strip 2b, and on the substrate 1 between two adjacent second conductive units 3a and located on one side of the second conductive connecting strip 3b, respectively. A clamping groove 9 is provided on the substrate 1 between two adjacent first conductive units 2a and located on the other side of the first conductive connecting strip 2b, and on the substrate 1 between two adjacent second conductive units 3a and located on the other side of the second conductive connecting strip 3b, respectively. In the adjacent first conductive connecting strips 2b and second conductive connecting strips 3b, the clamping piece 8 on the side of the first conductive connecting strip 2b is used to cooperate with the clamping groove 9 on the side of the second conductive connecting strip 3b.

[0047] The sheet is used to prepare an electrostatic dust removal filter element, such as Figures 5 to 10 The electrostatic dust filter element includes a housing 12 and an electrostatic dust collecting mechanism disposed in the housing 12. The electrostatic dust collecting mechanism is formed by folding the sheet material along the first fold 6 and the second fold 7 to form a plurality of parallel channels. After folding, each first conductive layer 2 and each second conductive layer 3 are alternately arranged and arranged in parallel, so that a dust collecting space is formed between adjacent first conductive layers 2 and second conductive layers 3, and a portion of the substrate between the first fold 6 and the second fold 7 serves as a supporting portion for supporting the formation of parallel channels, and the through hole 10 serves as a ventilation hole for air flow. The electrostatic dust filter element can be used in various dust removal equipment such as disinfection purifiers and fresh air purifiers.

[0048] The electrostatic dust collecting mechanism is formed by folding a whole sheet of material, omitting the swinging operation of the traditional single-piece electrode sheet, and when the electrostatic integrated mechanism is connected to the high-voltage positive and negative electrodes, it is only necessary to electrically connect the high-voltage negative electrode to the first conductive belt 4 through the connecting wire 11, and the high-voltage positive electrode to the second conductive belt 5 through the connecting wire. The electrostatic dust collecting mechanism has sufficient strength and can be simply installed in the outer casing, which greatly simplifies the production process of the electrostatic dust removal filter element and improves production efficiency.

[0049] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
