Description

Milk foaming device of coffee machine

Technical Field

The invention relates to the technical field of coffee machines, in particular to a milk foaming device of a coffee machine.

Background

At present, coffee machines on the market are various in types, various foaming devices are adopted, the problems of cleaning the foaming devices exist, and after the coffee machines are used for a period of time, the insides of the foaming devices can be blocked by dirt. And if the residual milk is not cleaned for a long time, the milk can deteriorate, and unnecessary damage is caused to the body of a user. Although some coffee machines are designed with the problem taken into consideration and the whole bubbler is arranged outside the machine to realize the problem of easy washing, the single function of the bubbler is inconvenient for making fancy coffee and needs more complicated steps. In addition, the other common structure can be assembled with the coffee outlet, but the structure solves the complex steps required by the fancy coffee making process, and is inconvenient to disassemble and wash, so that a user does not know how to assemble the fancy coffee in the original position after disassembling and washing, and is inconvenient to assemble and disassemble, and troubles are brought to the user.

In order to solve the above problems, a chinese utility model patent publication No. CN202681665U, a milk frothing apparatus for coffee machine (application No. CN201220288966.6), discloses a structure including a main body for generating milk froth, a connecting device for connecting a coffee machine, and a milk connecting pipe for milk to flow into the main body, the connecting device being connected to the left and right ends of the main body, the milk connecting pipe being provided on the connecting device at one end of the main body, and the milk connecting pipe being connected to the main body; the connecting device is provided with a connecting hook used for being connected with the coffee machine. The milk bubble device with the structure is bound with the coffee outlet, and complex operation is not needed when fancy coffee is made; the coffee machine can be detached from the coffee machine through the connecting hook on the connecting device, so that a user can conveniently detach, install and clean the coffee machine. However, it is necessary to ensure that the milk frothing device is assembled in the cavity of the coffee machine in a specific orientation during assembly to enable the milk to smoothly enter the frothing area, i.e. the milk tube is usually only installed at the right side of the coffee machine, and milk suction from the left side cannot be realized, which brings great inconvenience to the user.

Therefore, the foaming device of the present coffee machine is to be further improved.
