[0049] Embodiment 1

[0050] In order to solve the problems that the existing milk powder mixer relies on hot water flowing into the mixing bin to mix with the milk powder, which easily leads to uneven mixing of the milk powder and water, and moreover, when the milk powder and water are unevenly mixed, the milk powder is likely to accumulate at the liquid outlet, making the milk powder mixer not easy to clean.

[0051] As Figures 1 to 6As shown in the figure, this embodiment discloses a milk powder dispenser, which can automatically brew powdered foods such as milk powder, rice flour or soy milk. In this embodiment, milk powder is taken as an example for illustration. The milk powder dispenser includes a housing 1, a milk shaking device 2, a feeding device 3 and a hot water device 4 installed on the housing 1. A baby bottle 8 is placed on the milk shaking device 2. The feeding device 3 is used to store milk powder and put the milk powder into the baby bottle 8 according to a set amount. The hot water device 4 is used to store water and inject warm water with a set amount and a set temperature into the baby bottle 8. Through the milk shaking device 2, the baby bottle 8 can also be shaken to mix the warm water and the milk powder.

[0052] When using the milk powder dispenser, the user first selects the milk brewing parameters and activates the brewing function. According to the milk brewing parameters selected by the user, the hot water device 4 injects warm water with a set temperature and a set amount into the baby bottle 8. Then, according to the milk brewing parameters selected by the user, the feeding device 3 puts the set amount of milk powder into the baby bottle 8. Then, the milk shaking device 2 shakes the baby bottle 8 to mix the warm water and the milk powder evenly. When using the milk powder dispenser, the user can also first select the milk brewing parameters and activate the brewing function. Then, according to the milk brewing parameters selected by the user, the hot water device 4 injects warm water with a set temperature and a set amount into the baby bottle 8. The milk shaking device 2 shakes the baby bottle 8 at a slower first rotation speed. Then, according to the milk brewing parameters selected by the user, the feeding device 3 puts the set amount of milk powder into the baby bottle 8. The milk shaking device 2 shakes the baby bottle 8 at a faster second rotation speed to mix the warm water and the milk powder evenly.

[0053] Compared with the prior art in which hot water flows into the mixing chamber to mix with the milk powder, by shaking the baby bottle 8 through the milk shaking device 2, the warm water and the milk powder can be mixed more evenly, improving the milk powder brewing effect. Moreover, the milk powder and water are stored separately and mixed in the baby bottle 8. After the milk powder is brewed, there is no need to clean the milk powder dispenser. It is only necessary to clean the baby bottle 8 after the milk liquid is consumed, thereby reducing the possibility of bacteria breeding caused by incomplete cleaning of the milk powder dispenser and making the milk powder dispenser cleaner and safer.

[0054] As Figure 1 shown, specifically, the milk shaking device 2 includes a cradle 21 and a first driving member 22. The first driving member 22 uses a first motor. The first motor is installed on the housing 1. The cradle 21 is coaxially connected to the output shaft of the first motor. The baby bottle 8 is placed in the cradle 21. By driving the cradle 21 to rotate through the first motor, the baby bottle 8 is driven to rotate to mix the warm water and the milk powder evenly. Of course, a driving wheel can also be coaxially connected to the output shaft of the first motor, a rotating shaft can be coaxially installed at the bottom of the cradle 21, the rotating shaft is rotatably connected to the housing 1, and a driven wheel is coaxially installed on the rotating shaft. A transmission belt is sleeved on the driving wheel and the driven wheel. By driving the driving wheel to rotate through the first motor, the transmission belt drives the driven wheel and the rotating shaft to rotate, so that the cradle 21 can drive the baby bottle 8 to rotate to mix the warm water and the milk powder evenly.

[0055] A presence sensor is also provided inside the cradle 21. The presence sensor is used to detect whether the feeding bottle 8 is placed inside the cradle 21. When the feeding bottle 8 is in place, the brewing function can be activated. When the feeding bottle 8 is not in place, the brewing function cannot be activated, thereby reducing the possibility of milk powder and water leakage caused by user's incorrect operation. Among them, the presence sensor is specifically a weight sensor or an infrared sensor.

[0056] As Figures 1 to 4 shown, the feeding device 3 includes a milk powder can 30, a temporary storage bin 31, a milk powder detection sensor 39, a first shutter 32, a second shutter 33, a second driving member 34, a half gear 35 and two racks 36. The milk powder can 30 and the temporary storage bin 31 are fixed on the housing 1. The bottoms of the milk powder can 30 and the temporary storage bin 31 are both inclined downward. The temporary storage bin 31 is located on the side where the bottom of the milk powder can 30 is inclined downward. A first discharge port 301 is provided at the bottom of the milk powder can 30. A first feed port is provided on the temporary storage bin 31, and the first feed port is located at the first discharge port 301, so that the milk powder in the milk powder can 30 can flow into the temporary storage bin 31 more smoothly. A second discharge port 311 is provided on the temporary storage bin 31. A guiding nozzle 7 is also fixed at the bottom of the temporary storage bin 31. The guiding nozzle 7 is arranged towards the mouth of the feeding bottle 8. The milk powder in the temporary storage bin 31 falls to the guiding nozzle 7 through the second discharge port 311 and is guided into the feeding bottle 8 through the guiding nozzle 7.

[0057] The first shutter 32 is slidably arranged on the side wall of the milk powder can 30 and is used to block or open the first discharge port 301, and can control whether the temporary storage bin 31 feeds milk powder to the feeding bottle 8; the second shutter 33 is slidably arranged on the side wall of the temporary storage bin 31 and is used to block or open the second discharge port 311, and can control whether the milk powder can 30 replenishes the milk powder in the temporary storage bin 31. The milk powder detection sensor 39 is installed at the bottom of the milk powder can 30 and can detect the amount of milk powder put into the temporary storage bin 31 each time and the remaining amount of milk powder in the milk powder can 30, so as to accurately control the amount of milk powder put each time. It can also prompt the user to replenish when the amount of milk powder in the milk powder can 30 is less. The amount of milk powder put is specifically determined according to the number of times the milk powder in the temporary storage bin 31 is put into the feeding bottle. Under normal circumstances, the capacity of the temporary storage bin 31 is the amount of one spoonful of milk powder, and the amount of milk powder put is determined by the number of times of putting in the temporary storage bin 31. A flow detection member can also be provided at the second discharge port 311, and it is specifically a flow meter; the amount of milk powder put is determined by detecting the milk powder flow rate.

[0058] As Figures 2 to 4As shown, a first return spring 37 is installed at the top of the first shutter 32, and a second return spring 38 is installed at the top of the second shutter 33. The tops of the first return spring 37 and the second return spring 38 are fixed to the housing 1. Under the elastic force of the first return spring 37 and the second return spring 38, the first shutter 32 and the second shutter 33 move downward, the first shutter 32 seals the first discharge port 301, and the second shutter 33 seals the second discharge port 311. When it is necessary to open the first discharge port 301 or the second discharge port 311, the first shutter 32 or the second shutter 33 is driven to move upward by the second driving member 34.

[0059] The second driving member 34 is a second motor. The second motor is installed on the housing 1 and is located between the first shutter 32 and the second shutter 33. The half gear 35 is coaxially connected to the output shaft of the second motor. Two racks 36 are respectively installed on the first shutter 32 and the second shutter 33. The half gear 35 can only mesh with one of the racks 36 at the same time. When the first shutter 32 seals the first discharge port 301 and the second shutter 33 seals the second discharge port 311, the half gear 35 does not mesh with either of the two racks 36.

[0060] When it is necessary to put milk powder into the milk bottle 8, the second motor drives the half gear 35 to rotate clockwise. The half gear 35 meshes with the rack 36 installed on the first shutter 32, driving the first shutter 32 to move upward, opening the first discharge port 301. The milk powder in the milk powder can 30 flows into the temporary storage bin 31 through the first discharge port 301. When the set amount of milk powder in the milk powder can 30 has flowed out, the second motor drives the half gear 35 to rotate counterclockwise, so that the half gear 35 does not mesh with the rack 36 installed on the first shutter 32 and meshes with the rack 36 installed on the second shutter 33. At this time, the first shutter 32 closes the first discharge port 301 under the action of the first return spring 37, and the second shutter 33 moves upward under the drive of the second motor, opening the second discharge port 311, so that the milk powder in the temporary storage bin 31 can be put into the milk bottle 8 through the guiding nozzle 7, completing the quantitative input of the milk powder. After the milk powder input is completed, the second motor drives the half gear 35 to reset, that is, the half gear 35 does not mesh with either of the two racks 36, and the second shutter seals the second discharge port 311 under the action of the second return spring 38 to reduce the entry of foreign matters such as dust and moisture from the outside into the temporary storage bin 31.

[0061] According to the milk powder brewing parameters selected by the user, the milk powder detection sensor 39 measures the amount of milk powder that needs to be put into the temporary storage bin 31. The data measured by the milk powder detection sensor 39 controls the steering time of the second motor to timely close the first discharge port 301, and the quantitative input of the milk powder can be realized.

[0062] As Figure 1 and Figure 5As shown in the figure, the hot water device 4 includes a water tank 41, a water pipe, a flow meter 42, a first temperature sensor 43, a water pump 44, a first heating element 45, a second temperature sensor 46, a three-way valve 47, and a water injection assembly that are sequentially arranged on the water pipe. The water tank 41 is used to store water. A liquid level sensor is installed in the water tank 41. When the liquid level in the water tank 41 is low, it can remind the user to replenish water. The water inlet end of the water pipe is connected to the water tank 41, the water outlet end of the water pipe is connected to the first valve port of the three-way valve 47, the second valve port of the three-way valve 47 is connected to the water injection assembly, and the third valve port of the three-way valve 47 is connected to the water tank 41 through a return pipe.

[0063] The water in the water tank 41 is supplied into the first heating element 45 by the water pump 44 for heating. The heated water first returns to the water tank 41 through the first valve port and the third valve port. The first heating element 45 is a commonly used heating element in the art, and its specific structure will not be elaborated here. After the water pump 44 operates for a set time, the temperature of the heated water is more stable. The warm water heated to the set temperature enters the water injection assembly through the first valve port and the second valve port, and is injected into the milk bottle 8 through the water injection assembly, so that the water temperature entering the milk bottle 8 can be controlled more accurately, improving the brewing effect of milk powder and reducing the damage to the nutritional value of milk powder.

[0064] As Figure 1 and Figure 5 As shown in the figure, the water injection assembly includes a water injection nozzle 481 and a third driving member 482. The water injection nozzle 481 is a hose made of silica gel. The first end of the water injection nozzle 481 is connected to the second valve port of the three-way valve 47. The third driving member 482 is an electric push rod. The electric push rod is installed on the outer shell of the first heating element 45, and the output end of the electric push rod is fixedly connected to the second end of the water injection nozzle 481. When the electric push rod is started, the water injection nozzle 481 extends above the milk bottle 8 so that warm water can be injected into the milk bottle 8. After the water injection is completed, the electric push rod is started to reset, so that the water injection nozzle 481 is away from the milk bottle 8, in order to reduce the possibility that the water injection nozzle 481 affects the rotation of the milk bottle 8.

[0065] The water flow meter 42 can calculate the water output of the water tank 41. The first temperature sensor 43 detects the water temperature before heating, and the second temperature sensor 46 detects the water temperature after heating. According to the water temperatures upstream and downstream of the first heating element 45 and the target temperature, the heating power and the water inflow rate of the first heating element 45 are controlled so that the water temperature downstream of the heating element is the target temperature, thereby enabling precise control of the water injection volume and water temperature.

[0066] During use, according to the milk brewing parameters selected by the user, the water temperature and water volume to be injected are determined, and the water is injected into the milk bottle 8 through the water injection nozzle 481 to brew the milk powder. The hot water device 4 can also be used alone, and water is discharged according to the water temperature and water volume set by the user to provide hot water for the user.

[0067] As Figure 6As shown in the figure, further, the milk powder dispenser further includes a milk warming device 5. The milk warming device 5 includes a blower 52 and a second heating element 51. The blower 52 is installed on the housing 1. A duct 6 for connecting the blower 52 to the cradle 21 is provided on the housing 1. The second heating element 51 is installed in the duct 6. By starting the second heating element 51 and the blower 52, hot air can be blown onto the cradle 21 and the milk bottle 8 to keep the milk bottle 8 warm or heat it. For example, when the ambient temperature is relatively low, during the process of the cradle 21 rotating to mix the milk powder with warm water, the temperature of the milk liquid will decrease. By blowing hot air at a first set temperature onto the milk bottle 8 through the second heating element 51 and the blower 52, the milk liquid can be kept warm. The milk shaking device 2 and the milk warming device 5 can also cooperate to warm the milk. For example, for frozen or refrigerated milk liquid taken out of the refrigerator, the milk bottle 8 can be placed on the cradle 21, the first motor is started to rotate the milk bottle 8 on the cradle 21, the blower 52 and the second heating element 51 are started to blow hot air at a second set temperature onto the milk bottle 8 to heat the milk liquid, realizing the function of warming the milk.

[0068] Embodiment 2

[0069] This embodiment discloses a control method for a milk powder dispenser, and the milk powder dispenser is the milk powder dispenser in Embodiment 1. As Figure 7 shown, the control method mainly includes the following steps:

[0070] Inject water into the milk bottle 8.

[0071] Put milk powder into the milk bottle 8.

[0072] Perform a milk shaking operation on the milk bottle 8.

[0073] By shaking the milk bottle 8 through the milk shaking device 2, the warm water and the milk powder can be mixed more evenly, improving the milk powder brewing effect. Moreover, the milk powder and water are stored separately and mixed in the milk bottle 8. After the milk powder is brewed, there is no need to clean the milk powder dispenser, and only the milk bottle 8 needs to be cleaned after the milk liquid is consumed. Thus, the possibility of bacteria breeding due to incomplete cleaning of the milk powder dispenser can be reduced, making the milk powder dispenser cleaner and safer.

[0074] As Figure 8 shown, the control method specifically includes the following steps:

[0075] S1. The user selects the milk brewing parameters and starts the brewing function.

[0076] S2. Determine whether the milk bottle 8 is in place. If not, execute S21; if in place, execute S3.

[0077] S21. Remind the user that the milk bottle 8 is not in place.

[0078] S3. Start the third driving member 482 to extend the water injection nozzle 481 above the milk bottle 8. According to the milk powder brewing parameters selected by the user, start the water pump 44 and the first heating member 45 to operate at the set power. Open the first valve port and the third valve port of the three-way valve 47, and the water in the water tank 41 flows through the first heating member 45 and then returns to the water tank 41. According to the water temperatures upstream and downstream of the first heating member 45 and the target temperature, control the heating power of the first heating member 45 and the water inflow rate, so that the heated water temperature reaches the target temperature faster.

[0079] S4. After the water pump 44 operates for the first set time and the water temperature reaches the target temperature, open the second valve port of the three-way valve 47 and close the third valve port. The warm water is injected into the milk bottle 8 through the water injection nozzle 481.

The first shutter opens the first discharge port 301, and the milk powder in the milk powder can 30 flows out a set amount according to the milk powder brewing parameters selected by the user. Then, the second motor drives the half gear 35 to rotate counterclockwise, the first shutter closes the first discharge port 301, and the second shutter opens the second discharge port 311, and a set amount of milk powder is put into the milk bottle 8.

[0081] S6. Start the first driving member 22 to drive the cradle 21 to rotate, so that the warm water and the milk powder in the milk bottle 8 are mixed evenly.

[0082] S7. After the first driving member 22 operates for the second set time, stop and prompt the user that the brewing is completed.

[0088] Specifically, rotate at a low speed during the process of putting milk powder, and after the milk powder is put in place, then rotate at a high speed to perform the milk shaking operation.

[0089] First, shake the water in the milk bottle 8, and then add milk powder while shaking, which can make the warm water and milk powder mix more evenly and further improve the milk powder brewing effect. Moreover, the milk powder and water are stored separately and mixed in the milk bottle 8. After the milk powder is brewed, there is no need to clean the milk powder machine, and only the milk bottle 8 needs to be cleaned after the milk is drunk, so as to reduce the possibility of bacteria breeding caused by incomplete cleaning of the milk powder machine and make the milk powder machine cleaner and safer.

[0090] As Figure 10 shown, the control method specifically includes the following steps:

[0091] S1. The user selects milk powder brewing parameters and starts the brewing function.

[0092] S2. Determine whether the milk bottle 8 is in place. If not, execute S21; if in place, execute S3.

[0093] S21. Remind the user that the milk bottle 8 is not in place.

[0094] S3. Start the third driving member 482 to extend the water injection nozzle 481 above the milk bottle 8. According to the milk powder brewing parameters selected by the user, start the water pump 44 and the first heating member 45 to operate at a set power, open the first valve port and the third valve port of the three-way valve 47, and the water in the water tank 41 flows through the first heating member 45 and then returns to the water tank 41. According to the water temperatures upstream and downstream of the first heating member 45 and the target temperature, control the heating power and the incoming water flow rate of the first heating member 45 to make the heated water temperature reach the target temperature faster.

[0095] S4. After the water pump 44 operates for the first set time and the water temperature reaches the target temperature, open the second valve port of the three-way valve 47 and close the third valve port. The warm water is injected into the milk bottle 8 through the water injection nozzle 481. After reaching the set water volume, close the second valve port of the three-way valve 47 and start the third driving member 482 to reset.

[0096] S5. Start the first driving member 22 to drive the cradle 21 to rotate at the first rotation speed.

[0097] S6. Start the second driving member 34 to drive the half gear 35 to rotate clockwise. The first gate opens the first discharge port 301, and after the set amount of milk powder in the milk powder can 30 flows out according to the milk powder brewing parameters selected by the user, the second motor drives the half gear 35 to rotate counterclockwise, the first gate closes the first discharge port 301, the second gate opens the second discharge port 311, and the set amount of milk powder is put into the milk bottle 8.

[0098] S7. Control the first driving member 22 to drive the cradle 21 to rotate at the second rotation speed to make the warm water and milk powder in the milk bottle 8 mix evenly, where the second rotation speed is greater than the first rotation speed.

[0099] After the first driving member 22 operates for the second set time and stops, it prompts the user that the brewing is completed.
