Title: Static electricity recharging device for a used mask
Inventor: WOO SANG KI
IPC: H02N1/04
Filed: 2021-04-02
Granted: 2021-09-16
Abstract: In order to maintain a filtering effect of a mask using static electricity, the mask must have sufficient static charge. However, when electrostatic properties are exposed to air or come into contact with a human body, the amount of self-electrostatic charge naturally decreases, and an initial filtering effect gradually decreases, making it difficult to function as a mask. The present invention relates to a mask static electricity recharging device capable of recharging reduced or lost electrostatic charge in static electricity to enable a mask to be reused. The mask static electricity recharging device includes: a housing; two electrodes disposed in the housing, facing each other at a predetermined distance so that a mask can be inserted therein and covering at least a part of a filter of an electrostatic mask; and a voltage adjusting unit adjusting a voltage applied to the two electrodes from a power source.

The door stopper of the present invention is assembled with a hinge to which a rubber part is coupled on a bracket to which a double-sided adhesive tape is attached, such that the hinge rotates freely. A locking plate is formed to protrude from the inner surface of a bottom plate of the bracket, and a locking part formed on a lower portion of the hinge is engaged so that the rotation is controlled when exceeding a predetermined angle. Furthermore, a weight is provided on the inner surface of the hinge to facilitate rotation by self- weight, and protruding locking protrusions are provided on both sides of the rubber part so that the hinge can be firmly maintained between the side plates of the bracket when hinged.
