A plurality of through holes 504 are formed in the upper connecting piece 502 and the lower connecting piece 503, and the intermediate connecting piece 501 and the elastic protruding piece 203 are in contact with each other. The upper tab 502 and the lower tab 503 extend from the rear of the main bobbin 51 to the left and right wiring grooves 525 and 526, respectively. The upper connecting piece 502 and the lower connecting piece 50 3 of the first conductive sheet 55 are electrically connected to the negative bus line 53, respectively, and the upper connecting piece 502 and the lower connecting piece 503 of the third conductive piece 57 are electrically connected to the positive electrode bus line 54, respectively.

[0052] The second conductive sheet 56 is provided as an alternative to the second conductive sheet 55 connected to the negative bus line 53, and the second conductive sheet 56 functions the same as the second conductive sheet 55 except that the positions are set differently.

The second conductive sheet 55 and the third conductive sheet 57 are respectively disposed on the left and right sides of the dust collecting assembly 52.

[0053] In the same manner, the arrangement of the negative electrode sheets 521 is also different. The negative electrode tab 521 is provided with a latching recess 5201 at both ends of the outermost negative electrode tab 521 of the dust collecting member 52 for electrical connection with the second conductive sheet 56. The engaging groove 5201 also includes a guiding groove 5202 at the upper portion and a circular groove 5203 at the lower portion. The width of the guiding groove 5202 is smaller than the outer diameter of the negative bus line 53, and the inner diameter of the circular groove 5203 is larger than the outer diameter of the negative electrode bus 53. In this case, the direction of the engaging groove 5201 of the outermost negative electrode piece 521 is bilaterally symmetrical, and the mounting 吋 does not need to pay attention to the left and right mounting directions, and can be mounted in any one direction.

Referring to FIG. 15 again, the second conductive sheet 56 is provided with an intermediate connecting piece 50, an upper connecting piece 502' and a lower connecting piece 503, and the upper connecting piece 502' and the lower connecting piece 503 are respectively in the middle The connecting piece 501' is vertical, and a plurality of through holes 504' are respectively disposed on the upper connecting piece 502' and the lower connecting piece 503'. The intermediate connecting piece 50 and the elastic protruding piece 203 are in contact with each other, and the upper connecting piece 502' and the lower connecting piece 503 ' from The rear portion of the main skeleton 7 extends into the right wiring groove 526, and the upper connecting piece 502' is electrically connected to the right end portion of the negative electrode tab 521, and is electrically connected to the negative electrode bus 53 through the left end portion of the negative electrode tab 521. The lower tab 503' is not connected to the negative tab 521.

[0055] The radius of the arc of the negative electrode tab 521 and the positive electrode tab 522 is 30 mm to 100 mm. In the present embodiment, the negative electrode sheet 52

1 and the radius of the arc of the positive electrode sheet 522 is 55 mm, thereby changing the inherent trajectory of the particulate matter, changing the moving incident angle of the parabola of the particulate matter, enhancing the adhesion of the particulate matter on the electrode plate, and significantly improving the purification ability, and simultaneously effectively The purpose of enhancing structural strength.

[0056] The negative electrode sheet 521 and the positive electrode sheet 522 have a wall thickness of 0.1 mm to 2 mm. In the present invention, both the negative electrode sheet 521 and the positive electrode sheet 522 are made of an aluminum alloy sheet having a wall thickness of 0.15 mm, which greatly reduces the cost and reduces the weight, but does not impair the purification ability, but is more effective than the conventional electrostatic dust collecting device. %-10<3⁄4 or more.

[0057] A titanium oxide coating layer is provided on the outer surfaces of the negative electrode tab 521 and the positive electrode tab 522. Under the action of high-pressure field strength, it can catalyze and decompose organic gases such as formaldehyde and TVOC attached to the surface of the object, which can kill microorganisms, remove bacteria, eliminate odor and clean the air.

[0058] The distance between two adjacent negative electrode sheets 521 and positive electrode sheets 522 is 2.0 mm to 5 mm. Compared with the conventional electrostatic precipitator device, the electrode sheet can produce the same electric field strength compared with the electrode spacing of 6mm~8mm, and the voltage applied to the invention can be reduced to 50%~60<3⁄4, which solves the complicated process. The problem is that the discharge current between the negative electrode tab 521 and the positive electrode tab 522 is greatly reduced, which greatly reduces the discharge noise, saves energy, and has higher safety.

[0059] The ratio of the chord length to the chord height of the arc of the positive electrode tab 522 and the negative electrode tab 521 is 3 to 40. The positive electrode sheet 522 and the negative electrode sheet 521 of this embodiment have a chord length of 25 mm and a chord height of 1.6 mm. If the ratio of the chord length to the chord height is less than 3, the wind pressure loss is too large to meet the requirements for use of the dust collecting device. If the ratio of the chord length to the chord height is greater than 40, the mechanical strength requirements of the dust collecting device cannot be met. Under the conditions of the negative electrode sheet and the positive electrode sheet of the same width, the dust collecting device of the present embodiment has the characteristics of no ozone, no discharge noise, high dust collecting efficiency, and easy cleaning, compared with the prior art.
