Description

Technical Field

[0001] The invention relates to the technical field of milk frothing machines, and in particular to a milk liquid discharging system for a milk frothing machine. Background Art

[0002] A milk frother, also known as a steam coffee machine or steam milk frother, is an important accessory or component of a coffee machine. Its main function is to produce hot steam or milk foam for making various coffee and tea drinks, such as latte, cappuccino, etc.

[0003] The working principle of traditional milk frothers is to heat water to a high temperature and generate steam, and then use the pressure of the steam to heat the milk and make fine milk foam. Some high-end milk frothers are also equipped with temperature control and steam pressure adjustment functions so that users can control the temperature and texture of the milk foam more accurately, but they are limited to hot milk foam.

[0004] In addition, compared with a manual milk pump, a milk frother is more convenient and quicker because it can automatically produce steam and milk foam, greatly improving the efficiency of making coffee. At the same time, the milk frother can also be used to heat and stir other liquids, such as chocolate sauce, syrup, etc., so that they can be better integrated into the drink. At present, the control performance of existing milk frothers is not ideal. Summary of the invention

[0005] To solve the above problems, the present invention discloses a milk discharge system for a milk frothing machine, which adopts a gear pump whipping method, controls the density of the milk froth by adjusting the gear speed and air ratio, and can produce cold / hot milk froth, greatly improving the product application scenarios.

[0006] The specific plan is as follows:

[0007] A milk liquid outlet system for a milk frothing machine, characterized in that it comprises a water inlet joint, a milk circuit solenoid valve, a three-way solenoid valve, an F-type three-way, a gear pump and a nipple which are connected in sequence, the F-type three-way is also connected to an air regulating solenoid valve, and the gear pump is used to perform gear stirring on milk and air in a certain proportion to form milk foam containing air.

[0008] As a further improvement of the present invention, an air flow limiting hole is provided at the upper end of the air regulating solenoid valve, and a check valve is provided between the lower end and the F-type three-way valve.

[0009] As a further improvement of the present invention, the diameter of the air flow limiting hole is 0.5 mm.

[0010] As a further improvement of the present invention, a milk flow limiting hole is provided at the outlet of the gear pump.

[0011] As a further improvement of the present invention, the diameter of the milk flow limiting hole is 0.7 mm.

[0012] As a further improvement of the present invention, a heating plate is provided between the gear pump and the nipple.

[0013] As a further improvement of the present invention, a non-contact liquid level sensor is provided between the milk circuit solenoid valve and the three-way solenoid valve.

[0014] As a further improvement of the present invention, a non-contact liquid level sensor is provided between the three-way solenoid valve and the F-type three-way valve.

[0015] The beneficial effects of the present invention are: it has the advantages of simple operation, safety and reliability, time saving, versatility and strong adjustability; it can automatically heat milk or foam milk, and the generated milk foam is more delicate and rich; it can quickly heat milk and make milk foam, which greatly improves the efficiency and quality stability of making coffee and tea drinks compared with manual operation and whipping principles; it can not only be used to make milk foam, but also to heat and stir other liquids to make them better blend into drinks; users can more accurately control the temperature and texture of milk foam according to their own tastes and needs, which can better lower the threshold for making coffee and has broad market prospects.
