[0013] Specifically, Figure 1 , Figure 2 and Figure 4 The entire external structure of a milk frothing machine according to an embodiment of the present application is shown. Figure 5 and Figure 6 A schematic structural diagram of a hidden part of a milk frothing machine body 6 according to another embodiment of the present application is shown, showing the composition structure of the air intake assembly 1 . Figure 7 and Figure 8 The structure diagram of the hidden part of the milk frothing machine 6 of another embodiment of the present application is shown, wherein a heat preservation container 74 is arranged outside the material storage part 21, and a refrigeration device such as a compressor 71 and a heat exchanger 72 is arranged inside the body 6. The working principle of the milk frothing machine of the present embodiment of the application to generate milk froth beverages is as follows: the air intake component 1 sends air into the milk frothing generating component 3 through the air supply pipe 11; the feeding component 2 sends the 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 driver 33 ( Figure 6 ) pump body 31 (shown in Figure 6 ) and the three-way valve assembly 32 ( Figure 6As shown in FIG. 1 , the pump body 31 is used to pump the air in the air delivery pipe 11 and the material in the material delivery pipe 22 into the three-way valve assembly 32 and into the whipping shaft assembly. The driver 33 is used to provide driving force for the pump body 31 and the whipping shaft assembly. The whipping shaft assembly is used to mix the air and the material (milk or milk mixture) and form rich and delicate milk foam through high-speed oscillation. The milk foam generated by the milk foam generating assembly 3 flows out through the liquid outlet 62 on the outer wall of the body 6, thereby forming the final beverage, i.e., milk foam or milk froth. The control module is electrically connected to the air intake assembly 1 and the milk foam generating assembly 3, so that the milk foam machine can automatically generate milk foam beverages. Among them, the set density of the beverage refers to the density of the milk foam beverage actually required by the user, and the actual density of the generated beverage refers to the density of the milk foam actually generated by the milk foam machine. The calculation method of the milk foam density is to divide the mass of the milk foam output from the milk foam generating assembly 3 by the volume of the milk foam. The density of the milk foam beverage is proportional to the concentration of the milk foam beverage.

[0014] In the milk frothing machine of the embodiment of the present application, the control module is electrically connected to the air intake component 1 and the milk frothing generating component 3, so that the milk frothing machine of the present application can automatically generate milk frothing beverages. A regulating valve 12 is arranged on the air supply pipeline 11, and the regulating valve 12 can change the air supply flow rate of the air supply pipeline 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 measuring component 4 and a control module. The measuring component 4 can automatically measure the actual weight and actual volume of the milk frothing beverage generated by the milk frothing generating component 3. The control module is electrically connected to the measuring component 4 to obtain the actual weight and actual volume of the generated beverage. The control module obtains the actual density of the generated beverage according to the actual weight and actual volume of the generated beverage, and the control module can also obtain the set density of the ideal beverage required by the user. The control module compares the set density of the beverage with the actual density of the generated beverage, and drives the air intake component 1 to adjust the air supply flow rate according to the comparison result. In this way, the milk frothing machine provided in the embodiment of the present application can accurately and automatically adjust the concentration of the generated milk frothing beverage according to the set density of the beverage actually required by the user and the actual density of the generated beverage. The milk frothing machine provided in the embodiment of the present application can accurately adjust the concentration of the generated milk froth beverage according to the actual needs of the user through the control module, the measuring component 4 and the regulating valve 12, so as to meet the diverse and personalized needs of the user for the concentration of milk froth generated by the milk frothing machine. Compared with the method of manually adjusting the air flow rate of the air intake component in the prior art, the milk frothing machine provided in the embodiment of the present application has a high level of automation, saving labor costs and operation time.

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

[0016] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the milk frothing machine further comprises an input component 5 , which is electrically connected to the control module. The input component 5 is configured to input a set density of a beverage, and the control module is configured to obtain the set density of the beverage through the input component 5 .

[0017] Specifically, Figure 1 and Figure 2 As shown, the input component 5 can be configured to include a display screen 51 provided on the outer wall of the body 6 of the milk frothing machine, and at least one of a button 52 or a knob. The input component 5 can also be configured to include a remote operation panel. The input component 5 can be used to input the set density of the milk froth drink, and the input component 5 can also input parameters such as the set volume of the milk froth drink, the rotation speed of the whipping shaft component, etc. The input component 5 can also input the set concentration or milk froth type of the milk froth drink, and convert the milk froth concentration or milk froth type into the density data of the milk froth drink.

[0018] The set density of the beverage refers to the density of the milk froth beverage actually required by the user. The user inputs the density of the milk froth beverage actually required by the user to the milk froth machine through the input component 5, so that the control module electrically connected to the input component 5 can obtain the set density of the milk froth beverage actually required by the user, so as to compare it with the actual density of the generated beverage and adaptively adjust the air intake flow of the milk froth machine so that the concentration of the beverage generated by the milk froth machine can meet the actual needs of the user.

[0019] In an exemplary embodiment, Figure 2 and Figure 3 As shown, the measuring assembly 4 includes a volume measuring member 41, a weighing sensor 42 and a liquid level sensor 43. The volume measuring member 41 is configured to contain the generated beverage, and the inner cavity of the volume measuring member 41 has a preset cross-sectional area along the height direction perpendicular to the generated beverage; the weighing sensor 42 is configured to measure the actual weight of the generated beverage; the liquid level sensor 43 is configured to measure the liquid level of the generated beverage in the volume measuring member 41, so as to obtain the actual volume of the generated beverage; the weighing sensor 42 and the liquid level sensor 43 are both electrically connected to the control module.

[0020] Specifically, the liquid level sensor 43 is configured to measure the liquid level height of the generated beverage in the volume measuring member 41. When the liquid level sensor 43 detects the specific liquid level height of the generated beverage in the volume measuring member 41, since the cross-sectional area of ​​the inner cavity of the volume measuring member 41 is preset and known, the actual volume of the generated beverage in the inner cavity of the volume measuring member 41 can be obtained. The weighing sensor 42 and the liquid level sensor 43 are both electrically connected to the control module, and the weighing sensor 42 and the liquid level sensor 43 can send the actual volume and actual weight information of the generated beverage to the control module.

[0021] Optionally, the volume measuring component 41 uses a cup of preset volume to hold the generated beverage. The cup of preset volume may include multiple types, for example, a large cup and a small cup. The side walls of the large cup and the small cup are both provided with scale lines. The user first selects the cup type through the input component 5, and then uses the cup of this type to hold the generated beverage.

[0022] In some exemplary embodiments, Figures 2 to 4 As shown, the milk frothing machine further comprises a body 6, an outer wall of which is provided with a bracket 61, and the bracket 61 comprises a support and measurement portion 611 extending horizontally and in a plate shape.

[0023] One end of the support and measurement part 611 is connected to the body 6 , and a support groove 612 is provided at one end of the support and measurement part 611 away from the body 6 . The volume measuring piece 41 is supported in the support groove 612 , and the weighing sensor 42 is installed to the measurement support part 611 .

[0024] Specifically, the bracket 61 is arranged on the outer wall of the body 6, the support groove 612 of the support measurement part 611 of the bracket 61 is used to support the volume measurement member 41, and the weighing sensor 42 is installed on the measurement support part 611. The structure is simple in design, occupies a small space, and is easy to install and maintain. It can be understood that the bracket 61 can also be arranged outside the body 6 and not connected to the milk frothing machine body 6, which is within the protection scope of the present application.

[0025] The weighing sensor 42 can convert the gravity acting on the measured object into a measurable output signal in a certain proportion. In the embodiment of the present application, the support and measurement part 611 for mounting the weighing sensor 42 extends in the horizontal direction and is plate-shaped, which can improve the accuracy of the measurement result of the weighing sensor 42.

[0026] The weighing sensor 42 can be selected from various types of weighing sensors, all of which are within the scope of protection of this application. Since the weighing sensor 42 is close to the generated beverage and is easily affected by liquid splashing, the weighing sensor 42 can be equipped with a waterproof transmitter to increase the service life of the weighing sensor.

[0027] In an exemplary embodiment, Figure 3 and Figure 4As shown, the liquid level sensor 43 is configured as a photoelectric sensor.

[0028] The probe of the liquid level sensor 43 is configured to emit light along the horizontal direction toward the outer wall of the volume measuring piece 41; or, the probe of the liquid level sensor 43 is located above the volume measuring piece 41, and the probe of the liquid level sensor 43 is configured to emit light along the vertical direction toward the generated beverage in the volume measuring piece 41.

[0029] Specifically, in some exemplary embodiments, Figure 3 As shown, in order to reduce space occupation and facilitate installation and maintenance, the bracket 61 can be set to be L-shaped, and the probe of the liquid level sensor 43 is installed on the bracket 61, and emits light in the horizontal direction to a certain point position or multiple points on the outer wall of the volume measuring member 41. When the liquid level of the milk foam beverage generated in the volume measuring member 41 reaches the point position, the reflectivity of the light emitted by the liquid level sensor 43 on the outer wall of the volume measuring member 41 changes, so that the specific liquid level height of the milk foam beverage in the volume measuring member 41 is measured.

[0030] In some embodiments, the probe of the liquid level sensor 43 is installed above the volume measuring member 41, and the probe of the liquid level sensor 43 can emit light along the vertical direction toward the generated beverage in the inner cavity of the volume measuring member 41. The emitted light reaches the upper surface of the milk froth beverage in the inner cavity of the volume measuring member 41 and is reflected back, so that the change of the liquid level of the generated milk froth beverage can be detected, thereby obtaining the actual volume of the generated beverage in the volume measuring member 41.

[0031] Optionally, the photoelectric sensor may be a fiber optic sensor.

[0032] In some exemplary embodiments, Figure 5 and Figure 6 As shown, the air intake assembly 1 also includes a linkage 13 and a drive 14 , the drive 14 is electrically connected to the control module, the regulating valve 12 includes a valve stem (not shown in the figure), the linkage 13 is connected to the valve stem, and the drive 14 is connected to the linkage 13 .

[0033] The driving member 14 is configured to drive the linkage member 13 to move, thereby driving the valve stem to move, so as to adjust the air flow rate of the air delivery pipeline 11 .

[0034] Specifically, compared with the method in which the user manually twists the valve of the air supply pipe 11, the control module is electrically connected to the driving member 14, and the driving member 14 drives the regulating valve 12 through the linkage 13 to adjust the air supply flow rate of the air supply pipe 11. This can improve the mechanization level of the milk frothing machine and enable the milk frothing machine to accurately generate milk froth drinks of different concentrations.

[0035] The driving member 14 can be driven electrically or pneumatically, both of which are within the protection scope of the present application.

[0036] In some exemplary embodiments, Figures 5 to 8 As shown, the driving member 14 is configured as a stepping motor, the linking member 13 is configured as a reduction gear set, and the regulating valve 12 is configured as a needle valve.

[0037] Specifically, the valve core of the needle valve is a sharp cone, and the needle valve has the functions of precision adjustment and cut-off valve. The needle valve can adopt a micro-adjustment valve with scale and threaded interface. The needle valve and stepper motor can improve the precision of the air intake component 1 in adjusting the air flow.

[0038] In some exemplary embodiments, Figure 5 and Figure 6 As shown, the air supply pipe 11 includes an air inlet pipe 111 and an air outlet pipe 112, the air outlet of the air inlet pipe 111 is connected to the inlet end 121 of the needle valve, the air inlet of the air outlet pipe 112 is connected to the outlet end 122 of the needle valve, and the air outlet of the air outlet pipe 112 is connected to the milk froth generating component 3.

[0039] In some exemplary embodiments, Figures 7 and 8 As shown, the milk frothing machine also includes a temperature control component 7 and a body 6.

[0040] Specifically, the body 6 has the function of accommodating various functional components of the milk frothing machine. Milk is prone to bacterial growth and deterioration at room temperature, and the body 6 can also form a cavity with good sealing performance, which is conducive to the temperature control component 7 controlling the temperature of the material in the storage part 21 to the set temperature, thereby extending the shelf life of the material in the storage part 21.

[0041] Optionally, the temperature control component 7 can control the temperature of the material in the material storage part 21 to be 0 degrees to 8 degrees.

[0042] In some exemplary embodiments, Figures 7 and 8 As shown, the temperature control component 8 includes a refrigeration component and a heat preservation component. The refrigeration component includes a compressor 71, a heat exchanger 72 and a thermostat (not shown in the figure) arranged in the body 6. The temperature control component 8 also includes a fan 73 for heat dissipation and cooling arranged below the air intake component 1.

[0043] The heat preservation component includes a heat preservation container 74 and a cooling pipe (not shown in the figure) surrounding the outer wall of the heat preservation container 74 , and at least part of the material storage member 21 is located in the inner cavity of the heat preservation container 74 .

[0044] In some exemplary embodiments, the milk frothing machine is a double-head milk frothing machine (not shown in the figure), which is provided with a body 6, in which two sets of air intake components 1, two sets of feeding components 2 and two sets of milk frothing generating components 3 are provided, and the outer wall of the body 6 is provided with two liquid outlet nozzles 62.

[0045] Specifically, the milk frothing machine is configured as a double-head milk frothing machine, so that the two material storage parts 21 can contain different materials respectively, and the types of beverages flowing out of the two liquid outlets 62 are different. For example, one material storage part 21 contains milk, and the other material storage part 21 contains a mixture of milk and other materials. The two air inlet components 1 can generate milk froth beverages of two different concentrations.
