Emulsification device and beverage machine

An emulsification device of a beverage machine, wherein

• the emulsification device comprises a Venturi structure, the Venturi structure comprises a first mixing chamber and a second mixing chamber;
• the first mixing chamber is communicated with a first steam channel, a first liquid channel, a first air channel and an outlet channel, the second mixing chamber is communicated with a second steam channel, a second liquid channel, a second air channel and the outlet channel;
• the first steam channel and the second steam channel are configured to selectively communicate with a steam source, the first liquid channel and the second liquid channel are configured to communicate with a liquid storage source, the first air channel and the second air channel are configured to communicate with air;
• the outlet channel is configured to output a mixed fluid produced by the first mixing chamber or the second mixing chamber based on a Venturi effect;
• in a case that the first steam channel is communicated with the steam source, steam flows through the first steam channel into the first mixing chamber to produce a mixed fluid with a first temperature based on the Venturi effect;
• and
• in a case that the second steam channel is communicated with the steam source, steam flows through the second steam channel into the second mixing chamber to produce a mixed fluid with a second temperature based on the Venturi effect, and the first temperature is not equal to the second temperature.
