[0032] It should be noted that during the use of the milk frother, water and milk powder are placed in a specific box for use in the process of preparing the milk powder. When in use, the water is first heated to one hundred degrees Celsius. Boiling can effectively kill bacteria, viruses, parasites and other pathogens in the water, such as Escherichia coli, Salmonella and parasites, thereby reducing the risk of water-borne diseases. The water is then cooled to the required temperature to avoid water contamination. The required water and milk powder are then mixed, and the milk is output to the milk frother after stirring, thereby completing the automatic brewing of the milk. When in use, the time is set, and the time calculation module sends a prompt command to the prompt issuing module at the set time, and the prompt issuing module prompts the user to clean the box, thereby directly setting the milk frother for prompting The function of reminding users to clean the box body can avoid the situation that users forget to clean the box body after long-term use; the mixing body 101, milk powder tank 102 and water tank 104 are set to be a milk frother with model BQA8018-2, and the first solenoid valve 103 and the second solenoid valve 105 are used to control the amount of water and milk powder out of the milk powder tank 102 and the water tank 104. The solenoid valve is composed of an electromagnet, a valve core, a valve body and a spring. When the solenoid valve is not energized, the spring keeps the valve core on the valve seat, and the fluid cannot pass through the valve. At this time, the valve is in a closed state; when the solenoid valve is energized, when the current passes through the electromagnet, the magnetic force generated overcomes the force of the spring, so that the valve core moves to the open position, and the fluid can pass through the valve at this time. The valve is in an open state so that the fluid can pass through the solenoid valve.

[0033] Specifically, the breaking component 2 includes a stirring shaft 203 inserted and connected to the inner wall of the top end of the milk powder can 102, and a plurality of stirring rods 204 for breaking up the milk powder blocks are symmetrically fixedly connected to the bottom center of the stirring shaft 203.

A positioning block 202 is sleeved on the top of the stirring shaft 203, and a guide block 3 for guiding the movement of milk powder is arranged on the inner wall of the bottom end of the milk powder can 102.

[0034] It should be noted that a truncated cone-shaped hole with a top area larger than a bottom area is provided in the middle of the guide block 3. When in use, the milk powder is guided to the discharge port of the milk powder tank 102 by the hypotenuse of the truncated cone-shaped hole; the milk powder tank 102 is divided into a tank body and a tank cover, and the stirring shaft 203 is inserted and connected in the middle of the tank cover.

[0036] It should be noted that the temperature and humidity changes in different seasons will affect the environmental conditions inside the box. In humid seasons, boxes are more likely to accumulate moisture and bacteria, so they need to be cleaned and disinfected more frequently to avoid bacterial growth and mold growth, while in dry seasons, the cleaning interval can be appropriately extended. The set periodic input module is used to change the timing length in the time calculation module, so that the time interval for cleaning the box body can be modified in different seasons, and the set interval is sent to the time receiving module in the time calculation module. The time receiving module accepts the newly set time interval. The timing unit is used to count down from zero according to the set time. When the timing reaches the set time, the prompt trigger unit sends a command to turn on the prompt to the prompt issuing module, and sends the prompt through The part sends a reminder to the user that the box needs to be cleaned. When the user finishes cleaning the box, the user uses the reminder closing part to simultaneously close the reminder issued by the reminder issuing module and reset the timing in the timing part to zero, so that it restarts the timing; when making milk, the ratio of water and milk powder in the required milk water is set by the ratio setting module, so that the required amount of water and milk powder is directly calculated by the set amount of milk water required to be output, so that the required amount of water and milk powder is directly obtained by the powder water calculation part, and the amount of water and milk powder output is controlled by the water output control part and the powder output control part respectively to control the second solenoid valve 105 and the first solenoid valve 103, so as to avoid the waste of water and powder;

When setting, the ratio of water to milk powder can be set according to the selected milk powder brand and type and the preference of the milk drinker. When calculating, the required amount of water and milk powder is directly calculated according to the set ratio and the required amount of milk, so as to ensure that it is prepared in an accurate ratio. When both amounts are confirmed, the required water is controlled by the water output control unit, and the water is first heated to one hundred degrees Celsius through the heating and cooling modules in the milk frother, and then cooled to the required temperature. Finally, the required amount of milk powder is obtained through the powder output control unit, and the milk powder is poured into the cooled water. After stirring and other steps, the milk is poured into the feeding bottle through the milk output control unit, so as to ensure that the milk of the required concentration is brewed by the milk frother.

[0039] It should be noted that the increasing and decreasing part and the milk quantity confirmation part are used to replace the set amount according to the amount of milk required by the user, so as to adjust the control of the milk quantity. The specific steps are: firstly adjust the required amount of milk through the increasing and decreasing part, then determine the required amount of milk through the milk quantity confirmation part, and send it to the milk foaming control module, and obtain the milk of required concentration through the milk foaming control module; the set ratio modification part and storage part are used to set different concentrations of milk according to the selected milk powder brand and type and the preferences of the milk drinker, that is, the ratio of milk powder to water in the same cup of milk, and different concentrations of milk are brewed by setting different ratios of milk powder to water, so as to adapt to different brands of milk powder, improve the applicability of the milk foaming machine, and also better fit the user's preferences. After setting the ratio of each milk powder to water, The data will be stored in the storage unit so that when it is necessary to brew milk powder with the same proportion, the data in the storage unit can be directly used to avoid the need to repeatedly input the proportion data. When in use, the required ratio of milk powder to water is modified through the proportion modification unit, and the modified ratio of milk powder to water is sent to the powder and water calculation module. At the same time, the set ratio of milk powder to water is stored through the storage unit. When it is necessary to use the ratio data of milk powder to water in the storage unit, the ratio data of milk powder to water is directly called out from the storage unit; when the set periodic input module is used, the time interval is modified through the interval modification unit to increase and decrease the time interval until it is adjusted to the required time interval, and then the modification is confirmed through the modification confirmation unit, and the modified result is input into the time calculation module, thereby completing the modification of the prompt time interval.
