Title:
PARTICLE COLLECTION SYSTEM WITH DISCHARGING ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2019/140069
Kind Code:
A1
Abstract:
A particle collection system of an imaging apparatus includes an air flow generation device to generate an air flow for transporting airborne particles, a charging device that is located upstream of the air flow generation device in a ventilation direction to charge the floating fine particles in the air flow, and a particle collection device that is located downstream of the charging device in the ventilation direction to collect the airborne particles which are charged by the charging device. The charging device includes a discharging electrode and a counter electrode, and the particle collection device includes a tubular ventilation passage. A length of the tubular ventilation passage in the ventilation direction is greater than an opening diameter of the tubular ventilation passage, and the opening diameter of the tubular ventilation passage is less than or equal to a gap between the discharging electrode and the counter electrode.
