Description

Air inlet structure applied to steam milk frother Technical Field The utility model relates to the field of milk foaming devices, in particular to an air inlet structure applied to a steam milk frother. Background Coffee is a drink and gradually enters daily work, study and life of people. People can soak a strong and mellow coffee in the current fast-paced life, and the spirit can be greatly improved. With the increasing frequency of drinking coffee by people, more and more people need to use coffee machines to make coffee in outdoor travel or at home. In daily life, fancy coffee which we often drink is a drink prepared by mixing milk foam with coffee, and in order to generate milk foam, air needs to be sucked into milk and steam flow, and milk is generally sucked into a vacuum chamber by utilizing a siphon principle, and the effect is caused by the high speed of steam sprayed under pressure. In the existing steam sucking and foaming device, milk and clear water are easy to overflow through an air inlet in the sucking or cleaning process, so that air inlet blocking is caused by agglomeration after milk is dried, an air inlet structure is invalid, and therefore the air quantity introduced into a cavity is insufficient to support sufficient mixing of milk foam, and the taste of the milk foam is affected. Disclosure of utility model The utility model aims to solve the technical problem of providing an air inlet structure applied to a steam milk frother aiming at the current state of the art.
