Description

Foam maker with viscous liquid foaming function

Technical Field

The utility model relates to a foaming device with viscous liquid foaming function, which is suitable for a coffee machine or similar beverage extraction equipment and is directly connected with a liquid outlet end of the coffee machine to finish liquid outlet.

Background

Coffee machines are one type of beverage extraction devices, and generally comprise a water tank, an extraction element, a heating element, a water pump, etc. When the coffee machine is used, the coffee bag containing the coffee powder is placed in the extraction machine element of the coffee machine, the heated water is pumped into the chamber in the coffee machine where the coffee bag is placed by the water pump, the hot water flows through the coffee powder in the coffee bag, and the hot coffee flows into the cup from the water outlet channel of the coffee machine. There are many patents relating to beverage brewing devices or coffee machines, but the mechanisms for discharging the liquid (coffee) are the same, the beverage directly flows out through a channel, when hot water passes through a beverage bag, the water pressure is lost, the liquid discharging pressure is small, the oil ester in the coffee beverage is not fine and smooth, the oil ester layer is not thick enough, the coarse foam is more, and the taste of the beverage (coffee) flowing out from the existing liquid discharging mechanism is poor. The problems of less coffee oil and insufficient extraction oil and fat and the like frequently occur, and great challenges are generated for the production and debugging of the espresso coffee machine.

In view of the above situation, a chinese utility model patent "liquid outlet mechanism of a beverage brewing device" with patent number ZL201120154501.7 (publication number CN202060612U) discloses a liquid outlet mechanism of a beverage brewing device, which comprises a liquid outlet channel communicating an extraction space with the outside, and is characterized in that: the liquid outlet channel is internally provided with a plug which is supported by a spring and keeps the tendency of plugging the inlet of the liquid outlet channel. The beverage flowing out of the liquid outlet channel must overcome the elastic force of the spring, so the pressure of the beverage flowing out of the liquid outlet channel is increased, and the beverage with larger pressure compresses the bubbles with larger grain diameter to form the bubbles with the grain diameter between 30 microns and 0.5 nanometer, thereby completing one-time foaming.

Although the effect of the extracted coffee oil is improved, the coffee oil is still little, and the obtained coffee oil effect still does not reach the satisfaction degree of customers.
