Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The flow diagrams depicted in the figures are merely illustrative and do not necessarily include all of the elements and operations/steps, nor do they necessarily have to be performed in the order depicted. For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

The juicer control method can be applied to terminal equipment and a server, wherein the terminal equipment can be electronic equipment such as a mobile phone, a tablet computer, a notebook computer, a desktop computer and an intelligent television; the server may be a single server or a server cluster including a plurality of servers.

For example, when detecting that a motor of the juice extractor operates, the terminal device obtains a working voltage of a battery of the juice extractor, when the working voltage is less than or equal to a first preset voltage threshold, the terminal device controls the motor of the juice extractor to stop operating and controls the juice extractor to stand by, and then the terminal device obtains a voltage of the battery when the juice extractor stands by to obtain a standby voltage, and determines whether the standby voltage is less than or equal to a second preset voltage threshold, and if the standby voltage is less than or equal to the second preset voltage threshold, the juice extractor is locked so that the motor of the juice extractor does not operate, wherein the second preset voltage threshold is greater than the first preset voltage threshold.

It should be noted that the juicer control method may also be applied to juicers, such as portable juicers. The following explanation will be given taking the application of the method for controlling a juicer to a juicer as an example.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a juice extractor control method according to an embodiment of the present disclosure.

As shown in fig. 1, the method of controlling a juice extractor includes steps S101 to S104.

Step S101, when the fact that a motor of the juicer runs is detected, obtaining working voltage of a battery of the juicer.

The juice extractor is a seasonal product, and is generally used in summer, but is rarely used in winter. If the juicer is not used for a long time, the electric quantity of the battery is consumed by the internal resistance of the battery and the standby power consumption of the controller, and if the battery is over-discharged, the risk of permanent failure occurs. Therefore, the voltage protection point of the juicer is not suitable to be set too low, the juicer is not used for at least 6 months, and the over-discharge phenomenon of the battery does not occur.

In addition, when the motor of the juicer starts to work, the working current of the motor is large, the phenomena of ohmic polarization, electrochemical polarization, concentration polarization and the like in the battery of the juicer caused by large current are obvious, and the voltage of the battery can be quickly reduced. If the output voltage of the battery is reduced to a voltage protection point, the motor stops working. The existing juicer is usually stopped at low power when the stirrer is stirred to a half, then the voltage of a battery slowly rises after the juicer is stopped, the juicer can continue to work after a few minutes, and the juicer is repeatedly cycled.

The juicer can be a stirring juicer, a spray juicer, a juicing juicer, or can be a single-cylinder juicer, a double-cylinder juicer, a three-cylinder juicer, a round-cylinder juicer and the like. It should be noted that the juice extractor includes a motor and a battery, and when it is detected that the motor of the juice extractor is operated, the operating voltage of the battery of the juice extractor is obtained. Specifically, when the juicer detects that the motor runs, the processor of the juicer sends a voltage acquisition instruction to acquire the voltage of the battery to obtain the working voltage.

In one embodiment, the juice extractor comprises a battery voltage sampling circuit, the battery voltage sampling circuit is used for collecting the voltage of a battery, and the voltage of the battery of the juice extractor can be rapidly acquired through the battery voltage sampling circuit. Illustratively, as shown in fig. 2, the battery voltage sampling circuit 10 includes a resistor R3 and a resistor R4 connected in series with the battery, and a capacitor C2 connected in parallel with the resistor R4. The microprocessor 30 may collect the battery voltage ucd1 through the battery voltage sampling circuit 10.

In one embodiment, the juice extractor comprises a charging voltage sampling circuit and a charging port, wherein the charging voltage sampling circuit is used for judging whether the charging port of the juice extractor is charged or not and monitoring the voltage at the charging port, and the voltage at the charging port of the juice extractor can be quickly and conveniently acquired through the charging voltage sampling circuit. Illustratively, as shown in fig. 2, the charging voltage sampling circuit 20 includes a resistor R1 connected in series with the charging port, a resistor R2, a capacitor C1 connected in parallel with the resistor R2, and a diode D6 connected to VCC. The microprocessor 30 may collect the voltage ucd2 at the charging port through the charging voltage sampling circuit 20, and when the charging port is not charged, the voltage ucd2 is zero.

And S102, when the working voltage is smaller than or equal to a first preset voltage threshold value, controlling a motor of the juicer to stop running, and controlling the juicer to stand by.

When the working voltage is smaller than or equal to the first preset voltage threshold value, the electric quantity in the battery is considered to be too low, the motor of the juicer is controlled to stop running, and the phenomenon that the electric quantity in the battery is released too much and is over-discharged is prevented. After the motor of the juicer stops running, the juicer is controlled to be in standby mode, and at the moment, the electric quantity in the battery rises back, so that follow-up operation is facilitated. It should be noted that the first preset voltage threshold is a voltage protection point when the battery is in operation, and the first preset voltage threshold may be set according to an actual situation, for example, obtained through a large amount of experimental data, and the application is not particularly limited. It can be understood that the first preset voltage threshold is not easily set too high, which prevents the battery from easily triggering the above conditions to stop the operation of the juicer.

In one embodiment, the first predetermined voltage threshold is determined based on a nominal voltage of the battery and a first predetermined factor. The first preset coefficient can be flexibly set by a user, and the first preset voltage threshold is the product between the rated voltage of the battery and the first preset coefficient. For example, when the rated voltage of the battery is 5 volts and the preset coefficient is 0.7, the first preset voltage threshold is the product of the rated voltage and the first preset coefficient is equal to 3.5 volts, that is, when the motor runs, when the working voltage of the battery is detected to be reduced to 3.5 volts, the motor of the juicer is controlled to stop running, and the juicer is controlled to be in a standby state.

In an embodiment, the juicer has a plurality of batteries. When the batteries of the juicer are multiple, acquiring the number of the batteries and the rated voltage corresponding to each battery; and determining a first preset voltage threshold according to the number of the battery sections and the rated voltage corresponding to each battery. Specifically, a mapping table for representing a mapping between the number of battery sections and the rated voltage and the first preset voltage threshold is prestored in the memory or the database. Based on the mapping relation table, according to the number of the battery sections and the rated voltage corresponding to each battery, the corresponding first preset voltage threshold value can be quickly inquired, and when the working voltage of the battery is reduced to the first preset voltage threshold value, the motor of the juicer is controlled to stop running, so that the juicer keeps enough electric quantity according to the actual situation, and the battery is prevented from being damaged due to the over-discharge phenomenon of the battery.

It can be understood that different sections of batteries and different rated voltages cause different total electric quantities of the juicer and different discharging efficiencies of the batteries. Generally, the more the number of battery sections is, the higher the rated voltage of a single battery is, the higher the set first preset voltage threshold is; the lower the number of battery cells and the lower the rated voltage of a single battery cell, the lower the first preset voltage threshold value is set. Illustratively, the juice extractor has two lithium batteries, the rated voltage of a full charge of a single lithium battery is 4.2V, the rated voltage of the full charge of the two lithium batteries is 8.4V, and the first preset voltage threshold can be quickly determined to be 5.8V by inquiring the mapping relation table.

Step S103, obtaining the voltage of the battery when the juice extractor is in standby, obtaining the standby voltage, and judging whether the standby voltage is smaller than or equal to a second preset voltage threshold value.

It should be noted that the voltage of the battery can be collected by the battery voltage sampling circuit when the juicer is in standby state, so as to obtain the standby voltage. When the juice extractor is in standby, the resistance and the current of the load are far smaller than those of the load when the juice extractor works. In addition, according to the characteristics of the battery, the voltage of the battery will continue to rise after the battery is left idle for a period of time. Therefore, the standby voltage of the battery when the juicer is in standby is usually greater than the operating voltage of the battery when the juicer is in operation, and therefore the second preset voltage threshold is greater than the first preset voltage threshold.

The second preset voltage threshold is a voltage protection point when the battery is in a standby state, and the second preset voltage threshold can be set according to actual conditions, for example, obtained through a large amount of experimental data, and the application is not particularly limited. It can be understood that, although the second preset voltage threshold should be larger than the first preset voltage threshold, the second preset voltage threshold is not easily set too low, so that the juicer retains enough electric power according to practical situations, and even if the juicer is not used for a long time, the phenomenon of over-discharge of the battery and damage of the battery can not occur.

In some embodiments, the second preset voltage threshold may also be determined according to a rated voltage of the battery and a second preset coefficient. The second preset coefficient is larger than the first preset coefficient and can be flexibly set by a user, and the first preset voltage threshold is the product of the rated voltage of the battery and the second preset coefficient. For example, when the rated voltage of the battery is 5 volts and the second predetermined coefficient is 0.77, and the second predetermined voltage threshold is the product of the rated voltage and the second predetermined coefficient is equal to 3.85 volts, it is necessary to determine whether the standby voltage of the battery is less than or equal to the second predetermined voltage threshold of 3.85 volts.

In an embodiment, the juicer has a plurality of batteries. When the batteries of the juicer are multiple, acquiring the number of the batteries and the rated voltage corresponding to each battery; and determining a second preset voltage threshold according to the number of the battery sections and the rated voltage corresponding to each battery. For example, two lithium batteries exist in the juicer, the rated voltage of a single lithium battery when the single lithium battery is fully charged is 4.2V, optionally, the second preset voltage threshold is 6.5V, and details are not repeated here.

In one embodiment, the fruit and vegetable type and/or weight of the fruit and vegetable to be juiced are obtained; determining a juicing difficulty coefficient according to the type and/or weight of the fruits and vegetables, wherein the juicing difficulty coefficient is used for representing the juicing difficulty of the fruits and vegetables to be juiced; and adjusting the first preset voltage threshold and/or the second preset voltage threshold according to the juicing difficulty coefficient. Advantageously, the adjusted first preset voltage threshold and/or second preset voltage threshold are/is more accurate, and the implementation effect of the application is improved.

The fruit and vegetable includes pulp Citrulli, fructus Mali Pumilae, fructus Pyri, fructus Persicae, fructus Pruni, and optionally Chinese cabbage, caulis et folium Brassicae Capitatae, radix Raphani, radix Dauci Sativae, herba Alii Fistulosi, Bulbus Allii Cepae, Bulbus Allii, etc. The fruit and vegetable type can be determined according to the fruit and vegetable type information input before the user controls the juice extractor to operate; or the type of the fruits and vegetables can be obtained according to an image recognition technology; the weight of the fruits and vegetables can be acquired according to the weight sensor. It can be understood that the weight of the fruits and the vegetables is in direct proportion to the juicing difficulty coefficient, and the larger the weight of the fruits and the vegetables is, the higher the corresponding juicing difficulty coefficient is. When the juicing difficulty coefficient is higher, the first preset voltage threshold value and the second preset voltage threshold value can be correspondingly adjusted and reduced; when the juicing difficulty coefficient is lower, the first preset voltage threshold value and the second preset voltage threshold value can be correspondingly adjusted and increased, the adjustment relation can be set according to the actual situation, and the application is not particularly limited.

Exemplarily, when the juicing difficulty coefficient is higher, the working current of the juicer is higher, the ohmic polarization, the electrochemical polarization and the concentration polarization inside the battery caused by a large current are abnormal and obvious, the voltage drop can be very fast, and the working voltage is easily smaller than or equal to a first preset voltage threshold, so that the internal protection of the juicer is caused, and therefore, the first preset voltage threshold (or a second preset voltage threshold) is adjusted to be reduced, the working voltage is not easily smaller than or equal to the first preset voltage threshold, the condition that the juicer is shut down when half of the juicer works is avoided, and the user experience is improved.

Further, the hardness and/or the weight of the fruits and vegetables are determined according to the types of the fruits and vegetables to be juiced, and the juicing difficulty coefficient of the fruits and vegetables to be juiced is determined according to the hardness and/or the weight of the fruits and vegetables. It can be understood that the higher the hardness of the fruits and vegetables, the higher the juicing difficulty coefficient is, and the fruits and vegetables with higher hardness such as pears, coconut meat, apples, wild peaches, carrots and the like; the lower the hardness of the fruits and vegetables, the smaller the juicing difficulty coefficient, and the lower the hardness of the fruits and vegetables such as grapes, tomatoes, watermelons and the like. For example, the hardness of the pear is 3, the weight of the pear is 100 g, the hardness of the tomato is 1.2, and the weight of the tomato is 80 g, and by inquiring a mapping relation table between the hardness of the fruits and vegetables and/or the weight of the fruits and vegetables and the juicing difficulty coefficient prestored in a memory of the juicer, the juicing difficulty coefficient of the pear can be known to be 3.0, and the juicing difficulty coefficient of the tomato is known to be 0.96.

And step S104, if the standby voltage is less than or equal to a second preset voltage threshold, locking the juicer to enable a motor of the juicer not to run.

If the standby voltage is less than or equal to the second preset voltage threshold, the juice extractor is locked, so that the motor of the juice extractor does not run, that is, the juice extractor loses the juice extraction function and cannot be used by the user continuously. It should be noted that, if the standby voltage is less than or equal to the second preset voltage threshold, the juicer is not controlled to be locked, and the user is given the following steps: firstly, the battery has low electric quantity, the load output capacity which can be provided is limited, and the stirring effect is not good; secondly, the battery is easy to be over-discharged, so that the battery is easy to lose efficacy. Therefore, when the standby voltage is smaller than or equal to the second preset voltage threshold value, the single chip microcomputer limits the juice extractor not to output any more, or limits the motor of the juice extractor not to operate any more, and only when the follow-up requirements are met, the limitation is removed, and the user can normally use the juice extractor. For example, when it is detected that the standby voltage of the battery drops to 3.85 volts, equal to the second preset voltage threshold of 3.85 volts, the juicer is locked such that the motor of the juicer does not operate.

In one embodiment, after the juice extractor is locked, the juice extractor is controlled to perform a preset reminding operation to remind a user that the juice extractor is locked, low in electric quantity and/or to be charged. Wherein, the preset reminding operation comprises at least one of the following steps: broadcasting a preset reminding sound, lighting a preset breathing lamp and displaying preset reminding information. Illustratively, as shown in fig. 3, a display screen 11 and a breathing lamp 12 are installed on the juicer 10, when the juicer 10 is locked, the breathing lamp 12 lights up red, and the display screen 11 displays: if the juicer is locked, please charge. For another example, the juice extractor 10 is provided with a display screen 11 and a speaker 13, and the display screen 11 displays: if the juicer is locked, please charge; and the speaker 13 broadcasts: "juicer locked, please charge".

In an embodiment, after the juice extractor is locked, the method further comprises: monitoring an input voltage of a charging port of the juicer; when the input voltage is greater than or equal to a preset voltage threshold, the locking of the juicer is released, so that the juicer can operate based on an operation instruction input by a user. Illustratively, the input voltage ucd2 at the charging port is collected by the charging voltage sampling circuit 20, and the input voltage ucd2 is received by the microprocessor 30, as shown in fig. 2, and when the charging port is not charged, the voltage ucd2 is zero. When the input voltage ucd2 is greater than or equal to the preset voltage threshold, the locking of the juice extractor is released to enable the juice extractor to operate based on the operation instruction input by the user.

Further, after the locking of the juicer is released, the method further comprises the following steps: when detecting that a motor of the juicer runs, acquiring the voltage of a battery to obtain a first voltage; judging whether the first voltage is less than or equal to a first preset voltage threshold value or not; if the first voltage is less than or equal to a first preset voltage threshold, controlling a motor of the juicer to stop running, and controlling the juicer to stand by; and if the first voltage is greater than a first preset voltage threshold value, acquiring a current operation strategy of the juicer, and controlling a motor of the juicer to continuously operate based on the current operation strategy. For example, if the first preset voltage threshold is 5.8V, it is detected that the first voltage is 5.2V, that is, the first voltage is less than the first preset voltage threshold, at this time, the motor of the juice extractor is controlled to stop running, and the juice extractor is controlled to stand by. For another example, if the first preset voltage threshold is 5.8V, and it is detected that the first voltage is 6.2V, that is, the first voltage is greater than the first preset voltage threshold, and the current operation strategy of the juicer is obtained as "medium-grade and 1 minute for juicing", the motor of the juicer is controlled to continue to operate based on the current operation strategy, that is, to continuously operate for 1 minute according to the operation intensity of the medium-grade.

In an embodiment, after the locking of the juicer is released, the method further comprises: when the juicer is detected to be in a standby state, acquiring the voltage of a battery to obtain a second voltage; judging whether the second voltage is less than or equal to a second preset voltage threshold value or not; if the second voltage is less than or equal to a second preset voltage threshold value, the juicer is locked again; and if the second voltage is greater than a second preset voltage threshold value, controlling the juice extractor to operate based on an operation instruction input by a user. For example, if the second preset voltage threshold is 6.5V, it is detected that the second voltage is 6.2V, i.e. the second voltage is less than the second preset voltage threshold, at which point the juice extractor is re-locked so that the motor is not operated and the user cannot continue to use the juice extractor. For another example, if the second preset voltage threshold is 6.5V, and the second voltage is detected to be 6.8V, that is, the second voltage is greater than the second preset voltage threshold, the juice extractor is controlled to operate based on an operation instruction input by the user, for example, the operation instruction is "middle gear, juice extracting for 3 minutes", and the juice extractor is controlled to operate according to the operation instruction, that is, to operate for 3 minutes according to the operation intensity of the middle gear.

The juice extractor control method provided in the above embodiment includes obtaining a working voltage of a battery of the juice extractor when it is detected that a motor of the juice extractor is running, controlling the motor of the juice extractor to stop running and controlling the juice extractor to stand by when the working voltage is less than or equal to a first preset voltage threshold, obtaining a voltage of the battery of the juice extractor when the juice extractor stands by, obtaining a standby voltage, and determining whether the standby voltage is less than or equal to a second preset voltage threshold, and locking the juice extractor so that the motor of the juice extractor does not run if the standby voltage is less than or equal to the second preset voltage threshold. This application is through setting for two voltage protection points, first predetermineeing voltage threshold and first predetermineeing voltage threshold promptly, effectively prevents that the battery of juice extractor from not using for a long time and appearing the battery and cross the phenomenon of putting, avoids the juice extractor to appear the condition that work is just shut down half simultaneously, has greatly improved user experience.
