[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 ha

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, the milk feeding pipe conversion device of the milk frother of the present invention includes a milk feeding pipe, and the milk feeding pipe is composed of a milk inlet section connected with the milk storage tank and a milk outlet section connected with the milk frother. The conversion device also includes a ventilation pipe and a water inlet pipe connected with the water tank of the coffee machine. It can be seen from common sense that the length of the milk inlet section is much longer than that of the milk outlet section, so that most of the milk in the milk delivery tube can be returned to the milk storage tank later. The vent pipe is understood by common sense, that is, it is preferably a pipe that communicates with the atmosphere, but a ded...

Abstract

The invention discloses a milk feeding tube conversion device for a milk frother, which comprises a milk feeding tube, the milk feeding tube is composed of a milk inlet section connected with a milk storage tank and a milk outlet section connected with a milk frother, the milk inlet section There is a conversion body between the milk delivery section and a ventilation tube connected to the conversion body; when the conversion body is in the milk delivery state, the milk inlet section is connected with the milk delivery section; when the conversion body is in the milk return state, the milk inlet section connected to the vent pipe. The milk tube switching device of the milk frother can make the residual milk in the milk tube return to 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...
