Description

  The present invention relates to an electrostatic eliminator, and more particularly to an electrostatic eliminator with a greatly reduced thickness.

The prior art disclosed in Patent Document 1 will be described below based on the drawings. FIG. 1 is a cross-sectional view showing a conventional static eliminator. FIG. 2 is another cross-sectional view showing a conventional static eliminator.
As shown in FIGS. 1 and 2, the conventional static eliminator includes a housing 11, an electronic discharge module 12, a blower 13, a metal fixing part 14, and a removable ventilation window 15. The housing 11 is provided with an air guide tube 111 having a relative electrode 115 and a protruding portion 112. The protruding portion 112 has a high voltage end portion 113 on one side surface. The high voltage end 113 has an end end 114 at the end. The electronic discharge module 12 is provided with a fixing device 121 disposed on the high voltage end 113 side of the air guide tube 111. Further, the electronic discharge module 12 is provided with a discharge electrode 122 having a plurality of large diameter portions 123.

  Although the static eliminator has a static eliminating action, in assembling, the air guide tube 111 of the casing 11 arranges the electronic discharge module 12, and a removable ventilation window 15 is arranged on one side of the electronic discharge module 12, Since the ventilation window 15 is attached to one side of the air guide tube 111 at the same time, the thickness of the entire static eliminator is considerably increased, and the electronic product is currently required to be light and thin. But it could not meet the needs of users. The high-voltage end portion 113 comes into contact with the large-diameter portion 123 of the discharge electrode 122 and the protruding portion 112 of the air guide tube 111 due to the elastic deformation of the end end 114, but the end end 114 and the discharge electrode 122 are in contact with each other. In many cases, the force received by the large-diameter portion 123 is not average, so that a portion that contacts the power source and a portion that does not contact appear, and a spark is scattered due to poor contact of the large-diameter portion 123 to overheat the electronic component. This has hindered the operation of the product and greatly shortened the product life.
