Figures 4 to 6 A schematic structural diagram of a hidden body 5 of a milk frothing machine according to an embodiment of the present application is shown. Figures 7 and 8The structure diagram of the hidden body 5 of the milk frothing machine of another embodiment of the present application is shown, wherein a heat preservation container 84 and a cooling pipe 85 are arranged outside the material storage part 21. The air intake component 1, the material feeding component 2, the milk frothing generating component 3 and the control module are all located in the inner cavity of the body 5. The working principle of the milk frothing machine of the present application for generating milk froth is as follows: the air intake component 1 delivers air into the milk frothing generating component 3 through the air supply pipe 11; the feeding component 2 delivers material (the material is milk or a mixture including milk) into the milk frothing generating component 3 through the feeding pipe 22; the milk frothing generating component 3 includes a whipping shaft component (not shown in the figure), a driving component (not shown in the figure) and a pump component (not shown in the figure), the pump component is used for pumping the air in the air supply pipe 11 and the material in the feeding pipe 22 into the whipping shaft component, the driving component is used for providing driving force for the pump and the whipping shaft component, and the whipping shaft component is used for mixing the air and the material and forming rich and delicate milk froth through high-speed oscillation; the milk froth generated by the milk frothing generating component 3 flows out through the liquid outlet nozzle 52 on the outer wall of the machine body 5, thereby forming a final drink, namely milk froth or milk foam. Optionally, the milk frothing machine of the present application has a control module which is electrically connected to the air intake assembly 1, the feeding assembly 2, and the milk frothing generating assembly 3. The control module can control the operation of the air intake assembly 1, the feeding assembly 2, and the milk frothing generating assembly 3, so that the milk frothing machine can automatically generate milk frothing beverages. The set density of the beverage refers to the density of the ideal milk froth required by the user, and the actual density of the generated beverage refers to the density of the milk froth actually generated by the milk frothing machine. The calculation method of the milk froth density is the mass of the milk froth output from the milk froth generating assembly 3 divided by the volume of the milk froth. The milk froth concentration data is proportional to the milk froth density data. The milk frothing machine of the embodiment of the present application needs to generate a cup of milk froth beverage first during actual use. The user obtains the actual density of the cup of milk froth beverage by measurement and calculation, and then the user inputs the desired set density of the ideal milk froth into the milk frothing machine. The control module obtains the actual density of the cup of milk froth beverage and the desired set density of the ideal milk froth required by the user, compares them, and drives the air intake assembly 1 to adjust the air supply flow rate, so as to generate a milk froth beverage with a density that meets the user's needs.

[0014] The milk frothing machine of the embodiment of the present application is provided with a regulating valve 12 on the air supply pipe 11, and the regulating valve 12 can change the air supply flow rate of the air supply pipe 11. The regulating valve 12 can be a regulating valve 12 with a micro-adjustment function, so as to improve the adjustment accuracy of the regulating valve 12. The milk frothing machine is also provided with a control module, which is configured to compare the set density of the beverage with the actual density of the generated beverage, and drive the air intake component 1 to adjust the air supply flow rate according to the comparison result. In this way, the milk frothing machine of the present application can accurately adjust the density of the generated milk froth beverage according to the set density of the beverage combined with the actual density of the generated beverage, so as to meet the user's diverse and personalized needs for the milk froth concentration generated by the milk frothing machine.

[0015] For example, the content of the control module driving the air intake component 1 to adjust the air supply flow rate may include: if the actual density of the generated beverage is less than the set density of the beverage, the air supply flow rate of the air intake component 1 of the milk froth machine becomes smaller; if the actual density of the generated beverage is greater than the set density of the beverage, the air supply flow rate of the air intake component 1 of the milk froth machine becomes larger.

[0016] In an exemplary embodiment, Figure 1 As shown, the milk frothing machine further comprises an input module 4 which is electrically connected to the control circuit.

After the user obtains the actual density of the generated beverage through measurement and calculation, the operator needs to manually input the set density of the next cup of beverage and the actual density of the generated beverage into the input module 4.

[0019] In some embodiments, the milk froth machine of the present application is manually controlled to generate milk froth concentration. After obtaining the actual volume and actual weight of the generated beverage through measurement and calculation, the operator needs to manually input the set density of the next cup of beverage into the input module 4. The operator manually inputs the actual volume and actual weight of the generated beverage, and the control module needs to derive the actual density of the generated beverage based on the actual volume and actual weight of the generated beverage.

[0020] In some embodiments, the milk frothing machine of the present application semi-automatically controls the generation of milk froth concentration, and the actual weight data of the generated beverage can be automatically obtained by the input module 4 (for example, the device for measuring the weight of the generated beverage can be communicated with the input module 4), and the preset volume of the generated beverage is selected through the input module 4, and the cup 71 of the preset volume is used to hold the generated beverage. In this way, the input module 4 knows the actual volume of the generated beverage in advance. Therefore, the milk frothing machine of this embodiment does not require the user to manually input the actual volume and actual weight of the generated beverage into the input module 4, and is a milk frothing machine with semi-automatic control of the milk froth concentration.

[0021] The cup 71 of preset volume is used to contain the generated beverage, and the cup 71 of preset volume may include various types, such as Figure 1The large cup and the small cup can be included, and both the large cup and the small cup are provided with preset scale lines. The user first selects the type of cup 71 through the input module 4, and then the milk frothing machine stops working when the milk froth outputted from the milk frothing generating assembly 3 reaches the preset scale line of the cup 71. In the case of using a cup 71 of preset volume, the user can input the set mass of the drink and the actual mass of the generated drink into the input module 4, and the control module compares the set mass of the drink and the actual mass of the generated drink, and drives the air intake assembly 1 to adjust the air supply flow rate according to the comparison result.

[0022] It can be understood that the types of cups 71 with preset volumes used in the present application are not limited to large cups and small cups.

The milk frothing machine uses the volume measuring member 7 to hold the beverage. The side wall of the volume measuring member 7 is provided with scale lines. When the milk froth output from the milk frothing generating assembly 3 to the volume measuring member 7 reaches the scale line of the volume required by the user, the milk frothing machine stops generating milk froth. Then the user moves the volume measuring member 7 containing the milk froth to the weighing member 6 to measure the total weight of the milk froth and the volume measuring member 7. The actual weight of the generated beverage is equal to the total weight of the measured milk froth and the volume measuring member 7, minus the weight of the empty volume measuring member 7. The user measures the actual weight and actual volume of the generated beverage through both the weighing member 6 and the volume measuring member 7. The user manually calculates the actual weight of the generated beverage divided by the actual volume of the generated beverage to obtain the actual density of the generated beverage; or the user inputs the actual weight and actual volume of the generated beverage to the input module 4, and the control module of the milk frothing machine calculates the actual density of the generated beverage, which are all within the protection scope of the present application.
