Claim of US Patent No. 11,071,190

1. An electrostatic discharge device comprising:at least two conductive materials, attached to an outer wall of an insulating hollow tube, separating from each other and overlapping in a radial direction of the insulating hollow tube, when liquid carrying static charges flows through and rubs against the insulating hollow tube, the static charges are accumulated on the insulating hollow tube to generate an electrostatic voltage across the at least two conductive materials; and
at least one electrostatic eliminating circuit, electrically connected to the at least two conductive materials and disconnected from a grounding terminal, receiving and eliminating the static charges through the at least two conductive materials to reduce the electrostatic voltage.
