[0027] In this article, the terms "first interface," "second interface," and "third interface" are used to clearly indicate the connection method; the text has no other meaning.

[0028] In this article, the interfaces of components through which the fluid passes are considered to be in a closed circuit state, while the interfaces of components through which the fluid does not pass are considered to be in an open circuit state.

[0029] For ease of explanation, milk is used as an example in this article.

[0030] In this article, "interface 1 and 2" refers to the fluid passing through the first and second interfaces in sequence, "interface 1 and 3" refers to the fluid passing through the first and third interfaces in sequence, and so on.

[0031] When this device is working:

[0032] Making hot milk: Reference Figure 1 Start the forward and reverse fluid pump 3 to rotate forward and start the fluid heating device 4. The milk passes through the first valve body 2-3 interface, the forward and reverse fluid pump 3-2 interface, the fluid heating device 4-2 interface, the second valve body 6-3 interface, and the third valve body 8-2 interface in sequence, and is discharged through the liquid outlet 9 to realize the production of hot milk.

[0033] When making milk foam, milk enters the forward and reverse fluid pump at the same time as air enters the forward and reverse fluid pump. The rotation of the forward and reverse fluid pump mixes the milk and air to form milk foam.

[0034] Forward cleaning: Reference Figure 2 Start the forward and reverse fluid pump 3 to rotate forward. The fluid heating device 4 can be started or not. The water passes through the fifth valve body 12 interface 1 and 2, the first valve body 2 interface 2 and 3, the forward and reverse fluid pump 3 interface 1 and 2, the fluid heating device 4 interface 1 and 2, the second valve body 6 interface 1 and 3, and the third valve body 8 interface 1 and 3 in sequence, and is discharged through the waste liquid outlet 10 to achieve small-scale cleaning.

[0035] Reverse breast sealing: Reference Figure 3Start the forward and reverse fluid pump 3 to reverse, and turn off the fluid heating device 4. The water passes through the fifth valve body 12-3 interface, the second valve body 6-1 interface, the fluid heating device 4-1 interface, the forward and reverse fluid pump 3-1 interface, and the first valve body 2-3 interface in sequence. Then stop the forward and reverse fluid pump 3 to fill the pipeline with water without entering the milk storage container, thus achieving the effect of sealing the milk and preventing bacteria from growing in the pipeline.

[0036] As a method of making milk foam, the air intake pipe includes a sixth valve body 15, a first one-way valve 17, and a third connector 18. The first port of the sixth valve body 15 can be connected to the outside air, the second port of the sixth valve body 15 can be connected to the first port of the first one-way valve 17, the second port of the first one-way valve 17 can be connected to the third port of the third connector 18, the fifth port of the third connector 18 can be connected to the first port of the forward and reverse fluid pump 3, the third port of the first valve body 2 can be connected to the fourth port of the third connector 18, and the third port of the first valve body 2 is connected to the first port of the forward and reverse fluid pump 3 through the third connector 18.

[0037] Making cold milk foam: Reference Figure 4 The forward and reverse fluid pump 3 is started to rotate in the forward direction, and the fluid heating device 4 is turned off. The gas passes through the first and second ports of the sixth valve body 15, the first one-way valve 17, and the third connector 18 in sequence to enter the first port of the forward and reverse fluid pump 3. At the same time, the milk passes through the first valve body 2, the third connector 18, and the fourth and fifth ports to enter the first port of the forward and reverse fluid pump 3. The gas and milk are mixed under the action of the forward and reverse fluid pump 3 to form milk foam. The milk foam passes through the second port of the forward and reverse fluid pump 3, the first and second ports of the fluid heating device 4, the second valve body 6, the third valve body 8, and the second port in sequence, and is discharged through the liquid outlet 9 to realize the production of cold milk foam.

[0038] Making hot milk foam: Reference Figure 4 The forward and reverse fluid pump 3 is started to rotate in the forward direction, and the fluid heating device 4 is started. The gas passes through the first and second ports of the sixth valve body 15, the first one-way valve 17, and the third connector 18 in sequence to enter the first port of the forward and reverse fluid pump 3. At the same time, the milk passes through the first valve body 2, the third connector 18, and the fourth and fifth ports to enter the first port of the forward and reverse fluid pump 3. The gas and milk are mixed under the action of the forward and reverse fluid pump 3 to form milk foam. The milk foam passes through the second port of the forward and reverse fluid pump 3, the first and second ports of the fluid heating device 4, the second valve body 6, the third valve body 8, and the second port in sequence, and is discharged through the liquid outlet 9 to realize the production of hot milk foam.

[0039] After the milk foam is prepared, perform the forward cleaning as described above, and selectively perform reverse sealing.

[0040] In one embodiment, the intake pipe also includes a second connector 14, an air pump 20, a second one-way valve 21, a seventh valve body 19, and a first connector 7. The first port of the second connector 14 can be connected to the outside air, the third port of the second connector 14 can be connected to the first port of the sixth valve body 15, the second port of the second connector 14 can be connected to the first port of the air pump 20, the second port of the air pump 20 can be connected to the first port of the second one-way valve 21, the second port of the second one-way valve 21 can be connected to the first port of the third connector 18, the second port of the third connector 18 can be connected to the first port of the seventh valve body 19, the second port of the seventh valve body 19 can be connected to the first port of the first connector 7, the second port of the first connector 7 can be connected to the third port of the second valve body 6, and the third port of the first connector 7 can be connected to the first port of the third valve body 8. The device includes a fourth valve body 11, whose first interface is connected to a water source, and whose second interface is connected to the first interface of a fifth valve body 12. The fourth valve body 11 acts as a main switch, and the fifth valve body 12 is a three-way valve. This three-way valve always has one end open. By opening and closing the fourth valve body 11, the water inlet can be completely cut off.

[0041] The system requires periodic cleaning. After each batch of milk drinks is produced, the system can be set up in the background to perform periodic cleaning of the entire pipeline to ensure that no bacteria grow.

[0042] First, perform forward cleaning:

[0043] refer to Figure 2 When the forward and reverse fluid pump 3 is started to rotate forward, the fluid heating device 4 can be started or not. The water passes through the first and second ports of the fourth valve body 11, the first and second ports of the fifth valve body 12, the second and third ports of the first valve body 2, the fourth and fifth ports of the third connector 18, the first and second ports of the forward and reverse fluid pump 3, the first and second ports of the fluid heating device 4, the first and third ports of the second valve body 6, and the third valve body 8, and is discharged through the waste liquid outlet 10.

[0044] Then, perform air blowing on the first pipeline:

[0045] refer to Figure 5 When the air pump 20 is started, the gas passes sequentially through the second connector 14-2 interface, the air pump 20-2 interface, the second one-way valve 21-2 interface, the third connector 18-5 interface, the forward and reverse fluid pump 3-2 interface, the fluid heating device 4-2 interface, the second valve body 6-3 interface, the first connector 7-3 interface, and the third valve body 8-3 interface, and is discharged through the waste liquid outlet 10, or through the third valve body 8-2 interface and the liquid outlet 9.

[0046] Then, air blowing is performed on the second pipeline:

[0047] refer to Figure 6When the air pump 20 is started, the gas sequentially passes through the second connector 14 (interface 1-2), the air pump 20 (interface 1-2), the second one-way valve 21 (interface 1-2), the third connector 18 (interface 1-2), the seventh valve body 19 (interface 1-2), the first connector 7 (interface 7-3), and the third valve body 8 (interface 8), and is discharged through the waste liquid outlet 10, or through the third valve body 8 (interface 1-2) and the liquid outlet 9. This operating route allows for separate cleaning of residual milk residue in the liquid outlet and the waste liquid outlet to prevent blockage. A separate air path is also provided to clean residue in unsealed pipes during reverse sealing, as liquid milk used for frothing generally has a high protein and fat content, especially after heating. If residue is not cleaned promptly, it can clump and clog pipes and valves.

[0048] Then perform reverse breast sealing:

[0049] refer to Figure 3 Start the forward and reverse fluid pump 3 to reverse, and turn off the fluid heating device 4. The water passes through the fourth valve body 11-2 interface, the fifth valve body 12-3 interface, the second valve body 6-1 interface, the fluid heating device 4-1 interface, the forward and reverse fluid pump 3-1 interface, the third connector 18-4 interface, and the first valve body 2-1 interface in sequence. Then stop the forward and reverse fluid pump 3 to fill the pipeline with water without entering the milk storage container, thus achieving the effect of sealing the milk and preventing the growth of bacteria in the pipeline.

[0050] To facilitate temperature control, a second temperature sensor 5 is included, which is located between the second interface of the fluid heating device 4 and the first interface of the second valve body 6; a first temperature sensor 1 is included, which is located at the front end of the first interface of the first valve body 2.

[0051] To make the gas cleaner, the intake pipe includes a gas filter 13, which is located at the front end of the first interface of the second connector 14.

[0052] In one implementation, the forward and reverse fluid pump 3 is a gear pump, which mixes air and milk into milk foam through the gears of the pump.

[0053] In this device, the first valve body 2, the second valve body 6, and the third valve body 8 are all electric diaphragm valves to avoid milk contamination; it also includes a gas flow regulating valve 16, which is located between the second port of the sixth valve body 15 and the first port of the first one-way valve 17 to facilitate the adjustment of the air intake and change the viscosity of the milk foam.

[0054] In one implementation: the first valve body 2, the second valve body 6, and the third valve body 8 are selected as two-position three-way electromagnetic diaphragm valves; the fourth valve body 11, the sixth valve body 15, and the seventh valve body 19 are selected as two-position two-way electromagnetic valves; and the fifth valve body 12 is selected as a two-position three-way electromagnetic valve. The first valve body 2, the second valve body 6, the third valve body 8, the fourth valve body 11, the sixth valve body 15, the seventh valve body 19, the fifth valve body 12, the first temperature sensor 1, the forward and reverse fluid pump 3, the fluid heating device 4, the second temperature sensor 5, the gas flow regulating valve 16, and the air pump 20 are electrically connected to the control board. The control board is connected to a control switch or a control display screen that can start various working modes to realize automated operation.
