1. A water negative ion generating device comprising:
a water storage container having a water storage chamber;
a holder element having a placement channel communicated to the water storage chamber;
a friction buffer element made of cotton arranged in the placement channel;
a water mist generating circuit for driving the generation of negative ion water mist, wherein the water mist generating circuit comprises a sprayer element and a water negative ion spraying control unit electrically connected to the sprayer element, wherein the sprayer element comprises a spraying piece with spraying holes and a piezoelectric ceramic piece, so as to vibrate water to generate tiny water droplets through water resonance, at the same time, the tiny water droplets rub against the spraying piece for further acquiring negative electrons and forming negative ions which then diffuse into the environment through the spraying holes, wherein the sprayer element is used to vibrate and rub the water in the friction buffer element; and
a high voltage charging circuit, wherein the high voltage charging circuit comprises an ionization needle and an ionization control unit electrically connected to the ionization needle, wherein the water mist generating circuit and the high voltage charging circuit are grounded together, wherein the ionization control unit comprises a DC to high voltage drive module, wherein the ionization needle is electrically connected to the DC to high voltage drive module for generating electrons, wherein the DC to high voltage drive module increases a voltage of the ionization needle to −2 KV or above, wherein the ionization needle is arranged in a horizontal direction and the sprayer element is located adjacent to the ionization needle and arranged in a vertical direction.
