[0034] Reference Figures 1-9 A milk frother with quantitative cooling is described according to the embodiments of the utility model.

[0035] In one embodiment, as Figures 1-9 shown, a milk frother with quantitative cooling, the milk frother includes a kettle 1, a water collecting tank 2 and a controller.

[0036] The kettle 1 is provided with a first temperature sensor 11 and a heating element 12 at the bottom, and the water collecting tank 2 is provided with a second temperature sensor 21 at the bottom, and the kettle 1 is communicated with the water collecting tank 2 through the metering pump 3;

[0037] The water outlet of the water collecting tank 2 is connected to one end of the cooling device 5 through the water pump 4, the other end of the cooling device 5 is communicated with the water return port of the water collecting tank 2 through the electromagnetic valve 6, and the electromagnetic valve 6 is also communicated with the water outlet nozzle 7 of the milk frother;

[0038] The controller is connected with the first temperature sensor 11, the heating element 12, the second temperature sensor 21, the metering pump 3, the water pump 4, the cooling device 5 and the electromagnetic valve 6 respectively, so as to control these components.

[0039] The heating element 12 can be a heating wire or a heating disc, which is attached to the bottom of the kettle 1 to heat the water in the kettle 1; the first temperature sensor 11 is used to detect the water temperature in the kettle 1, and when the first temperature sensor 11 detects that the water in the kettle 1 reaches the boiling point temperature, the heating element 12 stops heating; the electromagnetic valve 6 has two water outlets, one of which is a normally open end for circulating the cooled water back to the water return port of the water collecting tank 2, and the other is a normally closed end for connecting the water outlet nozzle 7 for directly outputting the cooled water; the second temperature sensor 21 is used to detect the water temperature in the water collecting tank 2.

[0040] In specific implementation, the kettle 1 is filled with water, the heating element 12 first boils the water to boiling water, and the first temperature sensor 11 is set to stop the heating element 12 from working; the user presets the water volume and the cooled water temperature, and the milk frother draws the preset water volume of hot water from the kettle 1 through the pipeline into the water inlet at one end of the water collecting tank 2 through the metering pump 3, and the process is accurately controlled by the metering pump 3 to separate the water volume into the water collecting tank 2; then, the hot water is pumped out from the water outlet at the bottom of the water collecting tank 2 through the water pump 4 and transported to one end of the cooling device 5 through the pipeline; the cooled water returns to the water return port at the other end of the water collecting tank 2 from the other end of the cooling device 5 along the pipeline through the electromagnetic valve 6, and the water circuit is repeatedly circulated to realize the cooling of the water; when the second temperature sensor 21 detects that the water temperature in the water collecting tank 2 reaches the preset temperature, the controller controls the electromagnetic valve 6 to switch the water circuit so that the cooled water directly flows to the water outlet nozzle 7.

[0041] The above-mentioned embodiment provides a quantitative cooling milk frother, which quantitatively transports the water in the kettle 1 into the water collecting tank 2 through the metering pump 3, accurately and quickly controls the required capacity, then separately cools the water in the water collecting tank 2, and can quickly cool down, thereby shortening the cooling time and improving the cooling efficiency.

[0042] In this embodiment, the cooling device 5 includes a radiator 51 and a fan 52. The fan 52 is located on the side of the radiator 51, and the controller is connected to the fan 52. One end of the radiator 51 is connected to the outlet of the water pump 4, and the other end is connected to the inlet of the solenoid valve 6. The first outlet of the solenoid valve 6 is connected to the return port of the water collection tank 2, and the second outlet is connected to the outlet 7 of the formula maker.

[0043] The radiator 51 can be an aluminum heat sink or other types of heat dissipation pipes, such as copper pipes.

[0044] In practice, the water flow direction between the water collection tank 2 and the metering pump 3, water pump 4, radiator 51, and solenoid valve 6 is as follows: Figures 6-9 As shown by the middle arrow; based on the detection result of the second temperature sensor 21, the controller can command the solenoid valve 6 to switch between the first water outlet and the second water outlet. For example, when the second temperature sensor 21 detects that the water temperature in the water collection tank 2 drops to the set temperature, the controller will control the solenoid valve 6 to switch its water outlet, so that the water flowing out of the radiator 51 flows directly to the water outlet 7 of the milk maker and no longer flows back to the water collection tank 2.

[0045] Furthermore, an air intake shroud 53 is provided on one side of the fan 52, which can effectively protect the radiator 51 and the fan 52 while ensuring air circulation to guarantee the normal operation of the radiator 51 and meet its heat dissipation needs.

[0047] Among them, such as Figure 3 and Figure 4 As shown, the air inlet 81 can be a circular area composed of several horizontal strip-shaped through holes, which facilitates the intake of air to form an airflow. The air outlet 82 can be a rectangular area composed of multiple vertical strip-shaped through holes, which is similar in shape to the radiator 51, so that the airflow after absorbing heat can pass through and ensure the cooling effect.

[0048] In practice, after the fan 52 is turned on, it draws in cold air from the air inlet 81 on one side of the chassis 8. The cold air passes through the air inlet shroud 53, and the fan 52 blows the cold air toward the heat sink 51. When the cold air passes through the heat sink 51, it absorbs the heat of the hot water and turns into hot air. The fan 52 then blows the hot air directly out to the air outlet 82 on the other side of the chassis 8. Cold air in and hot air out can achieve air cooling.

[0049] In the embodiment, the front end of the machine body 8 is provided with a panel assembly 9, the panel assembly 9 comprising a controller; the water outlet nozzle 7 is arranged at the lower end of the panel assembly 9, and water can be conveniently taken.

[0051] In the embodiment, the bottom of the inner cavity of the machine body 8 is provided with a power board 91, and the power board 91 is used to connect an external power supply to supply power to the milk mixing machine. In specific implementation, the power board 91 is connected with the controller, the heating element 12, the metering pump 3, the water pump 4, the electromagnetic valve 6, the fan 52 and other components of the milk mixing machine to supply power for the operation of the milk mixing machine.

[0052] In the embodiment, the bottom of the kettle 1 is provided with a kettle seat 13, and the kettle seat 13 is arranged between the kettle 1 and the machine body 8. In specific implementation, the kettle 1 can be detachably arranged on the kettle seat 13, so that the kettle 1 can be conveniently installed and detached for cleaning.

[0053] In the embodiment, the bottom of the machine body 8 is provided with a base 10, so that the above-mentioned milk mixing machine can be conveniently placed and moved. In specific implementation, the bottom of the base 10 can be further provided with a plurality of foot pads, so that the whole machine can be placed more stably on a table top.

[0054] In the embodiment, the top of the kettle 1 is provided with a kettle cover assembly 14, which can close the opening of the kettle.
