Patent ID: 8392029

Claim:
An odor blender comprising: N component odor containers each configured to supply a component odor gas, wherein N is an integer of 2 or more, M carrier gas containers each configured to supply a carrier gas, wherein M is an integer of 1 or more and less than N, a blend part configured to blend the component odor gases, a blend line configured to lead the component odor gases from the N component odor containers to the blend part, a bypass line configured to discharge the component odor gases from the N component odor containers without passing through the blend part, N+M solenoid valves each of which is a three-way valve configured to have one of the N component odor containers and the M carrier gas containers communicate with any one of the blend line and the bypass line, and a control unit configured to control the switching of the connections by the N+M solenoid valves, wherein the control unit sets the number of the component odor containers connected to the blend line at the same time to M or less but not less than one out of the N component odor containers; connects the same number of the carrier gas containers to the bypass line as the number of the component odor containers connected to the blend line, and controls a time frame for the connection from the component odor container to the blend line per predetermined time period, based on a predetermined component odor gas mixing ratio.
