Particle collection vessel, particle collection device and particle collection method

A particle collection method in which particles in air are collected using a particle collection device, wherein:

• the particle collection device comprises:
• a particle collection vessel configured to charge the particles in the air and collect the particles;
• and
• a power supplying unit detachably attached to the particle collection vessel,
• the particle collection vessel comprises:
• a vessel body having an opening;
• a suction part provided in the opening and having an inflow path configured such that the air is flowed from an outside into an inside of the vessel body through the inflow path;
• a discharge part provided in the opening and having an outflow path configured such that the air is discharged from the inside to the outside of the vessel body through the outflow path;
• a discharge electrode provided in the inside of the vessel body and configured such that a high voltage is applied to the discharge electrode;
• and
• a medium storage part provided in the inside of the vessel body and capable of storing a medium for collecting the particles in the air charged by the discharge electrode,
• the power supplying unit includes:
• a suction flow path communicated with the inflow path of the particle collection vessel and configured such that the air is flowed into the inflow path through the suction flow path;
• and
• a discharge flow path communicated with the outflow path of the particle collection vessel and configured such that the air discharged from the outflow path is flowed through the discharge flow path,
• the particle collection vessel further comprises:
• a power supplying contact part formed in the suction part of the particle collection vessel;
• and
• a ground part configured to be in contact with the medium,
• the power supplying unit further includes:
• a power supplying member in contact with the power supplying contact part of the particle collection vessel and configured to apply the high voltage to the discharge electrode through the power supplying contact part;
• and
• a ground member in contact with the ground part of the particle collection vessel and configured to be grounded,
• the particle collection method comprises:
• a medium supplying process in which the medium is supplied into the vessel body;
• an air sucking process in which the air containing the particles is sucked into the vessel body after the medium supplying process;
• a particle charging process in which the particles in the air sucked in the air sucking process are charged by applying the high voltage to the discharge electrode;
• and
• a particle collecting process in which the particles charged in the particle charging process are collected in the medium supplied into the vessel body at the medium supplying process, and
• the particles contain microorganisms, bacteria and viruses.

A particle collection vessel configured to charge and collect particles in air, the particle collection vessel comprising:

• a vessel body having an opening;
• and
• an electrode unit that is detachably provided in the opening of the vessel body, wherein
• the electrode unit comprises:
• a suction part including a cylindrical body inside which an inflow path is formed, the inflow path configured such that the air is flowed from an outside into an inside of the vessel body through the inflow path;
• a supporting body supporting the cylindrical body;
• and
• a discharge part including an outflow path formed inside the supporting body and configured such that the air is discharged from the inside to the outside of the vessel body through the outflow path,
• the opening of the vessel body is formed at an upper portion facing a bottom portion of the vessel body,
• the inflow path and the outflow path penetrate the supporting body in an upper-and-lower direction,
• the cylindrical body includes one end opened to the outside of the vessel body and an other end opened to the inside of the vessel body,
• the electrode unit further comprises a discharge electrode provided at the other end of the cylindrical body and configured such that a high voltage is applied to the discharge electrode, and
• the vessel body comprises a medium storage part provided at the bottom portion of the vessel body and capable of storing a medium for collecting the particles in the air flowed into the inside of the vessel body and charged by the discharge electrode.
