Milk foaming steam pipe

Abstract

The invention relates to a milk foaming steam pipe which comprises an inner pipe internally provided with a steam channel. The milk foaming steam pipe is characterized by further comprising an outer pipe, a steam nozzle and a spray head, the outer pipe sleeves the inner pipe, an air channel is formed between the periphery wall of the inner pipe and the inner hole wall of the outer pipe, and the air channel and the steam channel are independent of each other; the steam nozzle is internally provided with a transition steam channel and a transition air channel which are independent of each other,a steam inlet end of the steam nozzle is insertedly connected to a steam outlet end of the inner pipe, and the upper portion of the steam nozzle is in threaded connection with the tail end in the outer pipe; the spray head is internally provided with a through hole, and an outlet end of the through hole is shaped like necking, the lower portion of the steam nozzle stretches into the through holeand is in threaded connection with the interior of the through hole of the spray head, and a negative pressure cavity is formed in the spray head below the steam nozzle. According to the steam pipe, it can be guaranteed that adequate air is mixed with the steam without complex operation, tiny air particles are directly formed to be put into milk to form milk foams, milk cannot be left in the innerchannel of the steam pipe basically, and use is more sanitary and healthier.

Description

technical field

[0001] The present invention relates to a milk frothing device for preparing steam milk froth, in particular to a milk frothing steam tube for automatically producing frothed milk. The device can be used together with or integrated into a coffee machine. Background technique

[0002] When drinking coffee, adding silky and delicate milk foam in the coffee can increase the taste and texture of the coffee, and can play a very good decorative role. The milk foam is the product of the fine mixing of milk and air. Devices for producing frothed milk have various structural forms.

[0003] The first is to directly fill the cup with cold milk, and use the steam wand nozzle directly connected to the steam pipe to prepare frothed milk, such as the Chinese utility model patent "A Milk Frothing Device" discloses such a milk frothing device. The steam emitted by the nozzle of the steam pipe forms a negative pressure space, and milk, air, and steam are mixed to form milk ...
