Technical field

The present invention relates to a milk froth producing device.

Background technique

When drinking coffee, the silky and delicate milk foam in the coffee can increase the taste and texture of the coffee, and it can play a very good decorative role. Milk foam is a product of fine mixing of milk and air. The way to make milk foam is to drive the air into the milk at a suitable temperature. Therefore, the general milk foam generating device will set a negative pressure chamber in the main body, and then the cold milk will be The air is delivered to the negative pressure chamber, and at the same time the high temperature steam is sprayed onto the surface of the mixed air milk to produce milk foam. In the existing milk foam generating device, the amount of air entering the negative pressure chamber cannot be adjusted, and the ideal thickness of the milk foam cannot be made according to actual needs. In addition, the existing open body directly connected to the negative pressure chamber is connected. Due to the small pore size, the pores are often blocked by the milk slag, which often causes malfunctions and is not very convenient to use.
