Milk delivery pipe switching device of milk foam device

Abstract

The invention discloses a milk delivery pipe switching device of a milk foam device. The milk delivery pipe switching device comprises a milk delivery pipe which is composed of a milk feeding sectioncommunicating with a milk storage tank and a milk discharging section communicating with the milk foam device, a switching body is arranged between the milk feeding section and the milk discharging section, and an air pipe is connected to the switching body. When the switching body is under a milk delivery state, the milk feeding section and the milk discharging section communicate with each other. When the switching body is under a milk returning state, the milk feeding section and the air pipe communicate with each other. According to the milk delivery pipe switching device of the milk foamdevice, residual milk in the milk delivery pipe can flow back into the milk storage tank.

Description

technical field [0001] The invention relates to a milk tube conversion device of a milk frother. Background technique [0002] When drinking coffee, adding a layer of milk foam (referred to as milk foam) on the surface of the coffee can enhance the taste. A milk frother is a device for making milk foam. The working principle of the milk frother is: feed milk, air and steam into the mixing chamber to make them mix and heat to produce milk foam. The milk tube is the line that connects the milk tank to the milk frother. [0003] The milk frother has the following defects in actual use: First, after the milk is foamed and sent into the coffee, due to the negative pressure, the milk in the milk delivery tube will not flow back into the milk storage tank, but will remain in the milk delivery tube. In the pipeline of the tube, the residual milk is easy to harden and deteriorate, which will not only affect the taste of the milk foam made in the later stage, but also cause the mil...

Problems solved by technology

[0003] The milk frother has the following defects in actual use: First, after the milk is foamed and sent into the coffee, due to the negative pressure, the milk in the milk delivery tube will not flow back into the milk storage tank, but will remain in the milk delivery tube. In the pipeline of the tube, the residual milk is easy to harden and deteriorate, which will not only affect the taste of the milk foam made in the later stage, but also cause the milk delivery tube to be blocked; secondly, the milk frother of the prior art is difficult to wash, and the milk frother needs to be removed. Disassembled from the coffee machine and rinsed with water, very inconvenient
