Description

Technical Field

[0001] The present invention relates to the technical field of breast milk shakers, and in particular provides a breast milk shaker and a control method thereof. Background Art

[0002] In the process of preparing milk powder, the milk bottle needs to be shaken, but everyone has different shaking techniques, and some people with poor techniques will have serious bubbling. For this reason, milk shakers came into being. The existing portable milk shakers on the market all have a single milk shaking function and lack heating and heat preservation effects. When used in cold weather, the water temperature is prone to drop rapidly when shaking the milk, which easily leads to poor dissolution of milk powder and ultimately leads to long milk shaking time and many bubbles, which is not conducive to the baby's drinking and nutrient absorption. Subsequently, milk shakers with heating and heat preservation functions appeared on the market, which can heat the milk bottle to warm the milk.

[0003] Existing milk shakers are equipped with a motor, which is connected to the cradle through a belt, gears or couplings, so that the motor can drive the cradle to rotate to perform milk shaking operations. However, when users use milk shakers to shake milk, there will be problems such as excessive vibration and noise, and there is even a risk of the milk bottle being separated and flying out; in addition, bubbles are easily generated during the milk shaking process.

[0004] Therefore, there is an urgent need for a milk shaker and a control method thereof to solve the above technical problems. Summary of the invention

[0016] Whether the current vibration frequency is appropriate is determined according to the first detection duration and the second detection duration.

[0017] In a specific implementation of the above-mentioned method for controlling a breast shaker, “determining whether the current frequency is appropriate according to the first detection duration and the second detection duration” includes:

[0018] If the absolute value of the difference between the first detection duration and the second detection duration is less than a preset difference, the current vibration frequency is appropriate;

[0019] If the absolute value of the difference between the first detection duration and the second detection duration is not less than a preset difference, the current vibration frequency is inappropriate.

[0044] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0045] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0046] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Existing milk shakers are equipped with a motor, which is connected to the cradle through a belt, gears or couplings, so that the motor can drive the cradle to rotate to perform milk shaking operations. However, when users use milk shakers to shake milk, there will be problems such as excessive vibration and noise, and there is even a risk of the milk bottle being separated and flying out; in addition, bubbles are easily generated during the milk shaking process.

[0048] In order to solve the above technical problems, the present embodiment discloses a milk shaker, which includes a housing, a cradle and a control module, wherein the cradle is arranged in the housing, and the ultrasonic vibration module is arranged at the bottom of the cradle, and the ultrasonic vibration module is used to ultrasonically vibrate the milk bottle, so as to shake the milk in the milk bottle. By using ultrasonic vibration to shake the milk, there is no need to use a motor to drive the milk bottle to rotate for shaking the milk, thus avoiding the problems of excessive vibration and noise in the process of shaking the milk, and there is no need to rotate the milk to shake the milk, so the milk shaking is relatively stable and a large number of bubbles will not appear.

[0049] The milk shaker further includes a heating module, wherein the heating module specifically includes a fan and a heater. The side wall of the cradle is hollowed out, and a receiving cavity is provided on the outside of the cradle. Hot air is introduced into the receiving cavity and enters the cradle through the hollow space of the cradle to heat the milk bottle. The air outlet of the fan is connected to the receiving cavity through an air duct, and the heater is provided in the air duct. The heater is used to heat the air in the air duct so that the air introduced into the receiving cavity is hot air, so as to heat the milk bottle and perform the milk warming operation.

[0050] Regarding the heating module, it should be noted that although air heating is adopted in this embodiment, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, water bath heating may also be adopted. Specifically, water is filled in the cradle, and an electric heater is arranged in the cradle, and the electric heater heats the water in the cradle to heat the milk bottle. This does not deviate from the basic principle of the present invention and will fall within the protection scope of the present invention.

[0051] The control module is arranged in the housing, the ultrasonic vibration module is electrically connected to the control module, and the control module controls the ultrasonic vibration module to operate so as to perform the milk shaking operation. The fan and the heater are both communicatively connected to the control module, and the control module can control the fan and the heater to perform the heating operation.

[0052] A temperature detection component is provided in the cradle, specifically a temperature sensor, which is provided on the bottom wall of the cradle and can be in direct contact with the milk bottle, and can directly detect the temperature of the milk bottle, so that the milk warming process can be adjusted in real time according to the temperature of the milk bottle during the milk warming process. The temperature sensor is connected to the control module, and the detected temperature information can be transmitted to the control module in real time, so that the control module controls the operation of the ultrasonic vibration module and the heating module to perform the milk warming operation. In addition, the control module is configured to be able to execute the control method of the milk shaker; specifically, to execute the milk shaking control logic and safety control logic of the milk shaker.

[0053] The control method of the milk shaker comprises the following main steps:

[0054] According to the current value of the ultrasonic vibration module, it is determined whether there is a milk bottle on the milk shaker.

[0055] Among them, “determining whether there is a bottle on the milk shaker according to the current value of the ultrasonic vibration module” specifically includes the following detailed steps:

[0056] When the current value is less than the first preset current value, no bottle is placed on the milk shaker; when the current value is smaller, it means that there is no load on the ultrasonic vibration module, so no bottle is placed on the milk shaker.

[0057] When the current value is not less than the first preset current value and less than the second preset current value, a milk bottle is placed on the milk shaker; wherein the second preset current value is greater than the first preset current value. At this time, the load of the ultrasonic vibration module is normal, so a milk bottle is placed on the milk shaker. At this time, the milk shaking operation can be performed, specifically, it can be in a standby state, so that the milk shaker can perform the milk shaking operation according to the needs of the user.

[0058] When the current value is not less than the second preset current value, the milk shaker will give an alarm; since the current of the ultrasonic vibration module is too large, this means that the ultrasonic vibration module has a fault, or the load is too large, resulting in an excessive current in the ultrasonic vibration module. The alarm can be issued so that the user can handle it.

[0059] like Figure 1 As shown, the control method of the milk shaker includes the following detailed steps:

[0060] S01, obtaining the current of the ultrasonic vibration module;

[0061] S02, determining whether the current current value is less than the first preset current value, if yes, no milk bottle is placed on the milk shaker; if no, proceeding to step S03;

[0062] S03, judging whether the current current value is less than the second preset current value, if yes, a milk bottle is placed on the milk shaker; if no, the milk shaker sends out an alarm.

[0063] The control method of the milk shaker also includes the following main steps:

[0064] The vibration frequency of the ultrasonic vibration module is determined according to the weight of the bottle.

[0065] Among them, the step of "determining the vibration frequency of the ultrasonic vibration module according to the weight of the milk bottle" can only be performed after the milk shaker detects that a milk bottle is placed in the cradle; it can avoid the ultrasonic vibration module from running idle, because the vibration frequency of the ultrasonic vibration module is set according to the conventional milk bottles on the market, and it cannot be adjusted to a suitable frequency during idle operation, and an alarm will be issued. In addition, idle operation will waste unnecessary electrical energy. Therefore, after detecting a suitable milk bottle, performing ultrasonic vibration can ensure that the vibration is effective. Moreover, the heating module heats the milk bottle after the milk shaker detects that a milk bottle is placed in the cradle.

[0066] Specifically, Figure 2 As shown in the figure, “determining the vibration frequency of the ultrasonic vibration module according to the weight of the milk bottle” specifically includes the following detailed steps:

[0067] S1, the ultrasonic vibration module operates at the initial frequency;

[0068] S2. Adjust the vibration frequency according to the waveform voltage.

[0069] The control method can automatically adjust the vibration frequency according to the waveform voltage after the milk bottle is placed, so that the milk can be shaken at a more appropriate vibration frequency, thereby ensuring both the effect of milk shaking and the safety of milk shaking.

[0070] Among them, Figure 3 As shown, step S2 "adjusting the vibration frequency according to the waveform voltage" specifically includes the following detailed steps:

[0071] S21, determining whether the current vibration frequency is appropriate according to the waveform voltage;

[0072] S22. When the current vibration frequency is not appropriate, adjust the vibration frequency, and then perform step S22 again.

[0073] Among them, Figure 4 As shown, step S21 "determine whether the current vibration frequency is appropriate according to the waveform voltage" includes the following detailed steps:

[0074] S211, obtain the first detection duration when the waveform voltage in a single cycle is greater than the first preset voltage and the second detection duration when the waveform voltage in the same single cycle is less than the second preset voltage; wherein the first preset voltage and the second preset voltage are symmetrical with respect to the waveform voltage symmetry axis; taking the waveform voltage of a sine function passing through the zero point as an example, the first preset voltage is a positive value, the second preset voltage is a negative value, and the absolute values ​​of the two are the same. Under normal circumstances, after the first preset voltage and the second preset voltage are both subtracted from the value a, the absolute values ​​of the two are the same. wherein a is a constant. wherein the first detection duration and the second detection duration are both not zero.

[0075] When obtaining the first detection duration, the voltage value of the waveform voltage is always obtained. When the voltage value is not greater than the first preset voltage, the first detection duration is controlled not to be counted. When it is detected that the waveform voltage is greater than the first preset voltage, the timing starts, and the waveform voltage continues to be detected whether it is greater than the first preset voltage. When the waveform voltage is not greater than the first preset voltage, the timing ends. When obtaining the second detection duration, the voltage value of the waveform voltage is always obtained. When the voltage value is not less than the second preset voltage, the second detection duration is controlled not to be counted. When it is detected that the waveform voltage is less than the second preset voltage, the timing starts, and the waveform voltage continues to be detected whether it is less than the second preset voltage. When the waveform voltage is not less than the second preset voltage, the timing ends.

[0076] S212: Determine whether the current vibration frequency is appropriate according to the first detection duration and the second detection duration.

[0077] Among them, “determining whether the current frequency is appropriate according to the first detection duration and the second detection duration” specifically includes the following detailed steps:

[0078] If the absolute value of the difference between the first detection time and the second detection time is less than the preset difference, the current vibration frequency is appropriate; at this time, the duration of the waveform voltage rises and falls by a large amplitude is almost the same, and the waveform voltage at this time tends to be a normal sine or cosine function curve, that is, the waveform voltage curve has a better periodicity, and the upper and lower chord curves are almost the same. The vibration frequency at this time is the optimal resonant frequency. The ultrasonic vibration module works at this vibration frequency, which can ensure that there is enough power to vibrate to ensure the effect of shaking the milk, and will not be too powerful, causing the milk in the bottle to splash; moreover, the amplitude of each vibration is the same, which can ensure that the vibration is relatively stable.

[0079] If the absolute value of the difference between the first detection time and the second detection time is not less than the preset difference, the current vibration frequency is inappropriate. At this time, the duration of the waveform voltage rises and falls significantly, and the upper and lower chord curves of the waveform voltage change greatly, which will make the vibration unstable and is not suitable for vibrating milk at this frequency.

[0080] Among them, in this embodiment, the initial frequency is the minimum vibration frequency, that is, the ultrasonic vibration module runs at the minimum vibration frequency when it is turned on. Step S22 "When the current vibration frequency is not suitable, adjust the vibration frequency" specifically includes: S221, increase the current vibration frequency by a preset value; wherein the preset value is a smaller value, which is the amplitude of each adjustment of the vibration frequency. If the difference between the minimum vibration frequency and the maximum vibration frequency is large, the preset value can be slightly larger. When the difference between the minimum vibration frequency and the maximum vibration frequency is small, the preset value can be slightly smaller, so that the number of adjustments within the adjustable range can be almost the same. The initial frequency is the minimum frequency, which can ensure that the vibration amplitude is small when it is initially turned on, and the phenomenon of milk splashing from the bottle will not occur.

[0081] In addition, step S211 includes: when the vibration frequency after increasing the preset value is greater than the maximum vibration frequency, an alarm is issued; specifically, a warning light and / or a buzzer can be used to prompt the user that there is no suitable vibration frequency to adapt to the current bottle, and the user needs to adjust the bottle.

[0082] Although the initial vibration frequency in this embodiment is the minimum frequency, this is not a limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, those skilled in the art may choose that the initial frequency is the maximum vibration frequency, and step S22 includes step S222, which includes: reducing the current vibration frequency by a preset value; at this time, step S211 includes: when the vibration frequency after reducing the preset value is less than the minimum vibration frequency, an alarm is issued. That is, try from top to bottom, and an alarm is issued if there is no suitable vibration frequency. Or, the initial frequency is greater than the minimum vibration frequency and less than the maximum vibration frequency; at this time, step S22 includes step S223, and step S223 includes: at the beginning, the current vibration frequency increases by a preset value; when the vibration frequency after increasing the preset value is greater than the maximum vibration frequency, the next time the vibration frequency is adjusted, the preset value is reduced on the basis of the initial frequency. At this time, step S211 includes: when the vibration frequency after reducing the preset value is less than the minimum vibration frequency, an alarm is issued. That is, try from bottom to top, and then from top to bottom, and an alarm is issued if there is no suitable vibration frequency. This does not deviate from the basic principles of the present invention and will fall within the protection scope of the present invention.

[0083] like Figure 5 As shown, the control method of the milk shaker includes the following detailed steps:

[0084] S001, the ultrasonic vibration module operates at the minimum vibration frequency;

[0085] S002, obtaining a first detection duration and a second detection duration;

[0086] S003, determining whether the absolute value of the difference between the first detection duration and the second detection duration is less than a preset difference, if yes, the ultrasonic vibration module vibrates and shakes the milk at the current vibration frequency; if no, proceeding to step S004;

[0087] S004, determining whether the current vibration frequency is greater than the maximum vibration frequency, if yes, the milk shaker issues an alarm; if no, proceeding to step S005;

[0088] S005, vibration frequency=vibration frequency+preset value; then perform step S02 again.

[0089] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
