Claim of US Patent No. 10,251,251

1. An electrostatic dissipation device with static sensing applicable to dissipate electrostatic charges on an object, comprising:an ion transmitting unit, including a casting, an air flow generator disposed in the casting, and an air flow control circuit electrically connected to the air flow generator;
an ion generating unit, including a circuit controller electrically connected to the air flow control circuit, an ion generating circuit electrically connected to the circuit controller, and at least one ion discharge needle disposed on the casting and electrically connected to the ion generating circuit; and
a static sensing unit, including a static sensor electrically connected to the circuit controller, and a static value is continuously detected and provided as feedback to the circuit controller by the static sensor, the circuit controller being configured to calculate a quantity of charge and a quantity of airflow for electrostatic dissipation;
when the static value on an object is detected by the static sensor is negative, the ion generating circuit controlled by the circuit controller enables the ion discharge needle to generate positive ions only, furthermore, the air flow generator controlled by the circuit controller enables the air flow control circuit to generate adequate airflow, wherein the positive ions are blown to the object for static neutralization; when the static value on the object is detected by the static sensor is positive, the ion generating circuit controlled by the circuit controller enables the ion discharge needle to generate negative ions only, furthermore, the air flow control circuit controlled by the circuit controller enables the air flow generator to generate adequate air flow, wherein the negative ions are blown to the object for static neutralization; when the static value is not detected by the static sensor, the operation of the ion generating circuit and the air flow generator are ceased by the circuit controller,
wherein an amount of the air flow is adjusted by the static value as detected.
