Drinking system with injector pump

A drinking system comprising:

• a drinking vessel defining a receiving chamber for a liquid,
• a drinking straw arranged in the drinking vessel and guided into the receiving chamber, with a first end having an inlet opening which projects towards a base of the receiving chamber and with a second end with a drinking opening, and with the drinking straw projecting from the drinking vessel and having a suction channel between the inlet opening and the outlet opening,
• a fragrance reservoir which is loaded with fragrance and has an inflow opening for air and an outflow opening for fragrance-enriched air,
• the drinking straw being connected or connectable to the outflow opening of the fragrance reservoir in order to suck in fragrance-enriched air emerging from the outflow opening, and
• an injector pump arrangement which is connected to or integrated into the drinking straw and is joined to the suction channel by a main flow path surrounded by an outer wall or is a component of the suction channel, and which has a suction opening which is led through the outer wall and is fluidically connected or connectable to the outflow opening of the fragrance reservoir, the injector pump arrangement having the following components integrated into the main flow path in a direction pointing towards the second end of the drinking straw:
• a drive nozzle,
• an expansion chamber fluidically connected directly downstream of the drive nozzle, and
• a collector nozzle fluidically connected directly downstream of the expansion chamber,
• wherein the suction opening leads into the expansion chamber.
