Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and in particular to a milk frothing device used in beverage machines such as coffee machines. Background Art

[0002] A beverage machine is a device that automatically makes beverages. It has been widely used in restaurants, schools, factories, homes and other places. The basic principle of a beverage machine is to automatically complete the beverage preparation process through a pre-set program. In terms of product structure, a beverage machine is mainly composed of a blender, pump, water tank, compressor, condenser, solenoid valve, control panel and other parts.

[0003] As the most commonly used beverage machine, the coffee machine is an electrical device mainly used to make coffee automatically. It combines coffee beans or coffee powder with water through certain technologies and mechanisms, and extracts the taste and aroma of the coffee through heating and pressurization.

[0004] The working principle of the coffee machine is mainly based on heating and pressure; usually, there is a water tank inside the coffee machine to store water. When the coffee machine is working, the heating element, usually a hot water heater or hot water pipe, heats the water to a suitable temperature, usually between 85℃ and 95℃. Then, the water pump draws water from the hot water tank and pushes it to the coffee powder placed in the filter with a certain pressure. When the hot water comes into contact with the coffee powder, it extracts the aroma, oils and dissolved substances in the coffee powder to form coffee liquid. The coffee liquid flows out through the filter and finally flows into the coffee cup or container.

[0005] As people's living standards improve, their pursuit of coffee flavors is becoming more and more diverse. In order to cater to people's various tastes, coffee machines are becoming more and more diversified. For example, while producing coffee, a layer of milk foam can be spread on the surface of the coffee to enrich the taste of the coffee drink. This process requires the participation of a milk foam generating device.

[0006] Most of the existing milk frothing devices adjust the size of milk frothing by controlling the size of the air intake. Based on this, Chinese patent CN215077615U discloses an adjustable milk frothing generator, which includes a body, the body includes a containing mechanism and a connecting channel vertically connected to the outer wall of the containing mechanism, a buffer chamber is provided in the connecting channel, an air intake assembly is provided in the buffer chamber, a liquid inlet is provided at the center of one end of the buffer chamber facing the containing mechanism, a connecting pipe is provided above the liquid inlet, the connecting pipe is vertically arranged with the connecting channel, an inlet is provided in the middle of the connecting pipe, the connecting pipe is connected to the buffer chamber space through the inlet, the two ends of the connecting pipe are respectively connected and connected with a milk inlet channel and an air channel, an adjusting assembly is provided on the side of the air channel away from the connecting pipe, and an air inlet is provided on the adjusting assembly; a liquid outlet is provided at the bottom of the containing mechanism; the negative pressure generated when the steam enters the containing mechanism through the liquid inlet from the air intake assembly drives the milk and air into the containing mechanism, the three are mixed to form milk froth, and milk froth with different tastes is formed by adjusting the air intake amount to meet different needs.

[0007] However, the milk frothing generator disclosed in the prior art still has the technical problem of complex structure. Specifically, in the technical solution of the milk frothing generating device disclosed in the prior art, the steam introduced from the outside enters the containing mechanism through the liquid inlet by the air inlet component, and the negative pressure generated at the same time drives the milk in the milk inlet channel and the air in the air channel into the containing mechanism, and the three are mixed to form milk froth. The air intake is adjusted by the adjustment component to form milk froth with different tastes, thereby meeting different user needs. However, the milk frothing generating device and its air intake adjustment structure disclosed therein are relatively complex, and the air intake adjustment component cannot be disassembled and cleaned, and is easily blocked, which affects the milk frothing performance.
