In addition, because different templates are arranged on different heights, the templates can be independently arranged and disassembled, so that the disassembly and the assembly of other templates are not influenced.
Of course, the electrostatic device 3 is not limited to the above configuration, and is of a wide variety. Since the mounting rail 33 of the electrostatic device 3 of the present invention can support a plurality of layers of electrostatic templates, the electrostatic templates are not limited to the above-described honeycomb frame and pin electrode form, and may have a modular structure of electrostatic templates of electrode plate to electrode plate.

As shown in fig. 9, preferably, the anti-creeping mounting spacer is a circular disk plate 335 connected to the outer circumferential wall of the mounting fence 33 through a center connection pole 339, and in order to minimize a creeping path D of grease creeping along the surface of the mounting fence 33 to the surface of the housing 1 of the range hood, the circular disk plate 335 is arranged centrally in the height direction of the mounting fence 33. It can thus be obtained that the value of the creepage path D is the sum of the value of the radius of the disc plate 335 and half the height of the mounting fence 33.
Wherein, center connection post 339 is the screw thread connection post, and the periphery wall of installation rail 33 is equipped with installation screw 309, and anti-creep electricity installation baffle passes through center connection post 339 spiro union in the installation screw 309 of installation rail 33.
