Specific embodiments

[0014] The following further clarifies the present invention in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0015] As shown in the figure, the present invention provides a brass drain valve applicable to a fresh - milk foaming machine, which includes a brass drain - valve body. The brass drain - valve body includes a horizontally arranged cavity. Quick - connect plugs 1 are respectively connected to the left and right ends of the cavity. The air proportion valve 2, the milk - line solenoid valve 3, and the water - line solenoid valve 4 are successively arranged from left to right at the top. The middle part of the front side is connected to the fresh - milk pipeline 5. The air proportion valve 2, the milk - line solenoid valve 3, and the water - line solenoid valve 4 are communicated with the cavity. Among them, a duck - bill check valve 6 is arranged at the lower end of the air proportion valve 2. The milk - line solenoid valve 3 is an isolated milk - inlet valve for controlling the on - off of the fresh - milk pipeline 5, and the water - line solenoid valve 4 is used to control the on - off of the pure - water pipeline 7.

[0016] In this embodiment, the quick - connect plug 1 at the left end of the brass drain - valve body is successively connected to the milk pump 8, the heating plate 9, the three - way solenoid valve 10, and the liquid - outlet nozzle. The quick - connect plug 1 at the right end is connected to the pure - water pipeline 7 through the flowmeter 11.

[0017] In this embodiment, the three - way solenoid valve 10 includes a milk - inlet / water - inlet, a milk - outlet / water - outlet, and a waste - liquid discharge port. Among them, the milk - inlet / water - inlet is connected to the heating plate 9, and the milk - outlet / water - outlet is connected to the liquid - outlet nozzle 12.

[0018] The working principle of this application is as follows:

[0019] S1. The milk pump starts to generate negative pressure to open the milk - line solenoid valve, suck the milk into the brass drain - valve body, and adjust the amount of air entering by adjusting the opening and closing size of the air proportion valve; the air is mixed into the fresh milk through the duck - bill check valve, and the milk and air enter the milk pump in a certain proportion, and are stirred and mixed by the milk pump to form milk foam;

[0020] S2. The milk foam enters the heating plate for instantaneous heating to ensure the quality of the milk foam;

[0021] S3. After heating, the milk foam enters the liquid - outlet nozzle through the three - way solenoid valve to complete the milk - foam output;

[0022] S4. After the milk foam is output, the water - line solenoid valve is opened, and the fresh milk in front of the air valve is pushed into the milk tank by water pressure to ensure that the fresh milk does not deteriorate; and by the flowmeter and the opening time of the milk - line solenoid valve, water is prevented from entering the milk tank, which can ensure that the fresh milk is always in a refrigerated state;

[0023] After the fresh milk is withdrawn into the milk tank, close the milk pipeline solenoid valve, switch the three-way solenoid valve, and the water is discharged into the wastewater pipe through the milk pump and the heating plate by the three-way solenoid valve to ensure that there is no fresh milk in the pipeline, which can prevent the fresh milk in the pipeline from deteriorating.

[0024] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
