Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. 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.

Fig. 1 is a schematic diagram of a frame structure of a swing control food processor according to some embodiments of the present application. In fig. 1, the shaking control food processor 1 includes a cup (not shown), a crushing blade 2, a battery 3 and a charging circuit 4 thereof, a control chip 5, an acceleration sensor 6 and a motor 7 connected to the control chip 5, and the crushing blade 2 is disposed in the cup and driven by the motor 7. The acceleration sensor 6 is used for acquiring acceleration sensing data of the food processor 1; the acceleration sensor data are used to determine oscillation parameters of the food processor 1, so that gesture operations of the user are recognized. The oscillation parameters of the food processor 1 comprise at least one of the following factors: a direction of oscillation of the food processor 1, an amplitude of oscillation of the food processor 1, a period of oscillation of the food processor 1, a number of oscillations of the food processor 1, and a trajectory of oscillation of the food processor 1. And the control chip 5 is used for controlling the food processor 1 to start or stop according to the acceleration sensing data. Based on the same idea, the control chip 5 can also be used to control other actions of the food processor 1, such as stirring speed, stirring duration, heating power, heating duration, etc., according to the acceleration sensing data.

It should be noted that the positional relationship of the partial structures in fig. 1 is exemplary and not limiting to the present application, and for example, the charging circuit 4 may be provided outside the cup body.

The swing-controlled food processor 1 in fig. 1 is mainly a handheld food processor 1 (abbreviated as food processor), and performs gesture operation by a user holding the food processor to implement at least part of control actions of the food processor, so that the advantages of the present disclosure can be better embodied, and generally, the user gesture operation includes at least one of the following factors: a direction in which the user shakes the food processor, a force with which the user shakes the food processor, a number of times the user shakes the food processor, a trajectory pattern in which the user shakes the food processor, and the like. For non-handheld food processors, the above solution, although also applicable, may reduce the number of user operation gestures supported. The gesture operation is mainly a shaking operation, and the shaking force, the number of times, the trajectory and the like required by the shaking operation can be specifically predefined according to needs.

Since the hand-held food processor is powered by a battery, the power is usually not high, and the power is weak for common processing actions such as crushing and stirring, and the processing effect is influenced. In this case, according to the present invention, the user can control the food processor by the swing operation, which not only improves the convenience of the user operation, but also improves the processing effect such as crushing and stirring when the food processor is operated by the swing operation.

The acceleration sensor 6 may include a linear acceleration sensor. Taking a three-axis acceleration sensor as an example, the three-axis acceleration sensor can detect linear accelerations in three directions of an X axis, a Y axis and a Z axis. Some technical parameters of the three-axis acceleration sensor are exemplarily listed in tables 1 and 2 below, which can be used as reference.

Table 1:

table 2:

data output rate	Corresponding to current consumption
		268Hz	50uA
134Hz	25.3uA
		67Hz	12.9uA
33.6Hz	3.7uA
		13.4Hz	2.9uA
3.7Hz	1.7uA

To facilitate detection of more complex shaking operations, the acceleration sensor 6 may also comprise an angular acceleration sensor, such as a six-axis gyroscope, so that the direction of rotation of the food processor can be detected.

Through the shaking control food processor in fig. 1, the starting or stopping is not controlled in a key mode, but is controlled through user gesture operations such as handheld shaking, so that on one hand, the user operation is more convenient, and on the other hand, taking a handheld food processor as an example, the user gesture operations such as handheld shaking can help the machine to more fully crush and stir, and the food processing effect is improved.

Through the acceleration sensing data, various state parameters can be directly or indirectly obtained, and the state parameters can reflect the characteristics of the user gesture operation and/or the characteristics of the interference signals, so that the user gesture operation is detected.

Five state parameters have mainly been considered in the scheme of this application, can the exclusive use, also can combine the use, and every kind of state parameter can both improve gesture detection's accuracy, and simultaneously, every kind of state parameter is especially unique advantage again respectively. These five state parameters include: acceleration amplitude, acceleration change period, gravity acceleration direction, acceleration change symmetry and acceleration change direction of the food processor. For convenience of detection, the acceleration amplitude, the acceleration change period, and the symmetry of the acceleration change may be respectively determined for one or more specific directions (e.g., X-axis, Y-axis, and Z-axis directions).

Generally, for the acceleration amplitude and the acceleration change period, the corresponding acceleration amplitude data and acceleration change period data can be obtained more directly from the acceleration sensing data, and for the other three state parameters, more analysis and determination may need to be performed on the acceleration sensing data. For convenience of description, the following embodiments are mainly described in detail by taking such an application scenario as an example.

In some embodiments of the present application, the acceleration sensing data may include acceleration amplitude data for determining a food processor swing amplitude that reflects a shake amplitude of a user shaking the food processor. In practical applications, the swing of the food processor is not necessarily caused by the user to perform the gesture operation, but may also be caused by the vibration of the motor 7, or by the user only carrying the food processor for other activities, so that these latter factors can cause interference to the gesture operation of the user, and the present application filters such interference by setting a reasonable acceleration amplitude threshold.

In particular, the user performing a gesture operation to shake the food processor is more likely to shake a magnitude of the shake than other shaking situations of the food processor, since this is a subconscious action by the user, which tends to perform the gesture operation harder in order for the food processor to respond correctly to the user's gesture operation. Based on this, the acceleration amplitude threshold value can be configured on the food processor in advance, and the control chip 5 can be based onThe acceleration amplitude data and the acceleration amplitude threshold value control the starting or stopping of the food processing machine, and the signal smaller than the acceleration amplitude threshold value is judged as the interference signal. In some test data, the acceleration amplitude due to motor vibration is typically less than 4m/s²The acceleration variation amplitude is generally less than 8m/s²For example, the threshold value of the acceleration variation amplitude can be set to be not less than 8m/s²The method is used for filtering the interference caused by the vibration of the motor, and for other similar interference, an appropriate acceleration amplitude threshold value can be set for filtering.

In some embodiments of the present application, as shown in fig. 5, the food processor includes a control board 8, the charging circuit 4 and the control chip 5 are disposed on the control board 8, and the control board 8 is mounted inside the food processor through a control board positioning structure (not shown in the drawings).

In some embodiments of the present application, the acceleration sensing data may include acceleration change period data for determining a food processor swing period reflecting a shaking speed at which a user shakes the food processor. In practical application, the food processor swinging is not necessarily caused by the user to perform gesture operation, and is also caused by the user walking or running with the food processor, so the following factors can bring interference to the gesture operation of the user, and the interference is filtered by setting a reasonable acceleration change period threshold value.

In particular, the user performs a gesture operation to shake the food processor, the swing speed is more likely than other shaking situations of the food processor, i.e., the swing period is more likely than other shaking situations of the food processor. Based on this, an acceleration change period threshold may be configured on the food processor in advance, the control chip 5 may control the food processor to start or stop according to the acceleration change period data and the acceleration change period threshold, and a signal greater than the acceleration change period threshold is determined as an interference signal, in some test data, the swing period of the food processor caused by the user gesture operation is about 200 to 500ms, and the acceleration change period of the person walking is about 1000 to 2000 ms.

In the above example, the acceleration amplitude threshold and the acceleration change period threshold are described by taking the example of configuring one threshold respectively, but of course, a plurality of thresholds may be directly configured to have corresponding ranges, for example, a range of 200 to 500ms of acceleration change period is configured, and a signal falling outside the range is determined as an interference signal caused by the user walking.

In some embodiments of the present application, the swing direction reflects the direction in which the user is currently shaking the food processor, which may also be one of the contributing factors of the user's operational gesture. The swing direction may generally include vertical swing (upright or inverted), horizontal swing (landscape).

The swing direction directly influences the gravity acceleration level of the food processor in all directions, the gravity acceleration is always vertical downwards, based on the gravity acceleration, a gravity acceleration value can be configured on the food processor in advance, the control chip 5 can determine the swing direction according to the gravity acceleration value and the acceleration components of the food processor in one or more directions, and then the food processor is controlled to start or stop according to the swing direction.

In some embodiments of the present application, the acceleration change of the food processor will have a certain symmetry when the user shakes the food processor because the food processor is doing reciprocating motion, thereby assisting the detection of the gesture operation of the user. If a logic for judging the symmetry of the acceleration change can be arranged in the food processor, the control chip 5 can control the food processor to start or stop according to the judgment result of whether the acceleration change has symmetry.

In some embodiments of the present application, it has been mentioned above that the acceleration sensor may also comprise an angular acceleration sensor, in which case the acceleration sensing data may also be used to determine an acceleration change direction of the food processor, which reflects a more specific trajectory pattern for a user shaking the food processor, such as a horizontal shake, a vertical shake, a rattle shake, a clockwise horizontal rotation, a counter-clockwise horizontal rotation, a flip, and so on. Based on this, the acceleration preset changing direction may be arranged in advance on the food processor, and the control chip 5 may start or stop the food processor according to the acceleration changing direction and the acceleration preset changing direction.

The above analysis of the acceleration sensor data for several uses in the solution of the present application, in combination with several uses thereof, helps to more accurately detect a user gesture operation, while based on the detection result, the food processor can be controlled to start or stop, and also to perform other predetermined actions.

More intuitively, some embodiments of the present application provide a schematic diagram of some acceleration sensing data of the food processor of fig. 1 in an application scenario, as shown in fig. 2a to 2g, to further assist the description.

Fig. 2a shows the acceleration sensor data in the X-axis direction when the food processor is stationary, and it can be seen that the acceleration sensor data is approximately a straight line and is substantially influenced only by the acceleration of gravity. Fig. 2b shows the acceleration sensing data in the X-axis direction when the motor 7 is started, and it can be seen that the acceleration amplitude is small, and it can be determined as a disturbance signal. Fig. 2c shows acceleration sensing data in the X-axis direction when the user wearing the backpack walks, and the acceleration change cycle at this time is relatively large, and therefore, the user can determine that the user is a disturbing signal. Fig. 2d shows the acceleration sensing data in the X-axis direction when the user shakes the food processor, and it can be seen that there are 9 large fluctuations in the figure, and it is determined that the user shakes 9 times in total according to the predetermined rule, and the control signal is valid. As can be seen from the figures, the acceleration change situation during shaking is obviously different from the disturbance caused by motor vibration or walking, and the gesture operation of the user and part of the disturbance signal can be distinguished through the acceleration amplitude and the acceleration change period.

Similarly, acceleration sensing data in the Y-axis direction and the Z-axis direction can be acquired, so that the calculated displacement situation can be calculated, the acceleration amplitude and the acceleration change period in any direction can be calculated according to the comprehensive displacement, and the gesture operation of the user can be accurately detected according to the direction.

The filtering of the partial interference signal is explained in more detail in connection with fig. 2d and 2 c.

In FIG. 2d, the acceleration amplitude is about 1800 (representing 18 m/s)²) The magnitude of the acceleration change is approximately 3600 (representing 36m/s 2). Some test data show that the acceleration change amplitude caused by the motor vibration is generally less than 8m/s². The user can easily reach 18m/s by hand shaking the food processor²Therefore, based on the acceleration amplitude or the acceleration change amplitude, it is easy to distinguish the motor vibration disturbance from the shake gesture operation. Some test data indicate that the acceleration variation period of the user hand-cranking food processor is about 200-500 ms, the acceleration variation period of the user walking is about 1000-2000 ms, and the acceleration variation period of the user running is similar to that of the hand-cranking food processor, but the running generates an asymmetric acceleration in one direction, and the interference signal caused by the running can be further filtered by whether the acceleration has symmetry. Comparing fig. 2d and fig. 2c, it can be seen that when the hand-held food processor shakes, the forces for the reciprocating shaking are nearly the same, so that accelerations with opposite directions and the same magnitude are generated, and the accelerations caused by actions such as running do not have the characteristics, so that the corresponding interference signals can be filtered.

Fig. 2e shows the acceleration data when the food processor is in the right position, the uppermost line shows the acceleration in the Z-axis direction, the middle line shows the acceleration in the Y-axis direction, and the lowermost line shows the acceleration in the X-axis direction, it can be seen that the accelerations in the X-axis direction and the Y-axis direction are close to 0, and the acceleration in the Z-axis direction has a value of 980, indicating that 1 g is 9.8m/s²The food processor is illustrated as being upright. Similarly, FIG. 2f is acceleration data for a food processor in a horizontal orientation, with the uppermost line representing acceleration in the X-axis direction, the middle line representing acceleration in the Y-axis direction, and the lowermost line representing acceleration in the Z-axis direction, as can be seenThe acceleration in the Y-axis direction and the Z-axis direction are close to 0, and the acceleration in the X-axis direction has a value of 980, indicating that the food processor is horizontal. Similarly, FIG. 2g shows acceleration data for a food processor inverted with the uppermost line representing acceleration in the X-axis direction, the middle line representing acceleration in the Y-axis direction, and the lowermost line representing acceleration in the Z-axis direction, and it can be seen that the acceleration in the X-axis direction and the Y-axis direction are close to 0, and the value of the acceleration in the Z-axis direction is-980, indicating that the food processor is inverted. Thus, it can be seen that the swing direction of the food processor can be determined relatively accurately from the acceleration sensing data.

Through the scheme, the gesture operation of the user can be detected accurately, the gesture operation of the user is various, various control schemes can be predefined, and the following exemplary list is a part of selectable schemes for controlling the food processor.

For example, starting up a food processor may for example employ the following:

the first scheme is as follows: the food processor is vertically shaken for more than two times, and the food processor starts to work for a fixed time. Specifically, the judgment is as follows: shaking in Z-axis direction with acceleration amplitude of 7.5m/s²(or the acceleration change amplitude is 15m/s²Hereinafter, the same applies) for more than two acceleration change periods of 200 to 500ms, and the food processor starts to work.

The second scheme is as follows: the food processor is shaken horizontally for more than two times, and the food processor starts to work for a fixed time. Specifically, the judgment is as follows: shaking in the X-axis direction or the Y-axis direction with an acceleration amplitude of 7.5m/s²And (3) continuing for more than two acceleration change periods of 200-500 ms, and starting the food processor to work.

In the third scheme: the food processor is shaken more than two times in any direction (such as vertical shaking, horizontal shaking, rattle shaking, etc.), and the food processor starts to work for a fixed duration. Specifically, the judgment is as follows: shaking in X-axis direction, Y-axis direction or Z-axis direction with acceleration amplitude of 7.5m/s²And (3) continuing for more than two acceleration change periods of 200-500 ms, and starting the food processor to work.

A fourth scheme: shaking the food processor in any direction starts the food processor to continue to operate, and stops shaking, and after a few seconds, the food processor stops operating. Specifically, the judgment is as follows: shaking in X-axis direction, Y-axis direction or Z-axis direction with acceleration amplitude of 7.5m/s²The period of acceleration change is 200 to 500ms, the shaking is continued, the food processor is continuously operated, the shaking is stopped, and the food processor is stopped after several seconds.

The fifth scheme is as follows: the food processor is turned over for one circle, and the food processor starts to work for a fixed time. Specifically, the judgment is as follows: detecting angular acceleration, turning over in Z-axis direction, and starting the food processor when the acceleration in Z-axis direction changes according to the turning characteristic.

The sixth scheme is as follows: the food processor rotates clockwise for one circle horizontally, and the food processor starts to work for a fixed time length. Specifically, the judgment is as follows: angular acceleration is detected, the food processor rotates in the X-axis direction and the Y-axis direction, the acceleration changes according to the clockwise rotation characteristic, and the food processor starts to work.

For another example, stopping the food processor may, for example, employ the following:

the first scheme is as follows: the working time is fixed and the automatic stop is realized. For example, if the set maximum operation time is 60 seconds, the operation is automatically stopped after 60 seconds of start-up.

The second scheme is as follows: after shaking was stopped, it was automatically stopped within a few seconds. For example, the food processor continues to operate while rocking is continued, and after the rocking is stopped, the food processor automatically stops within 5 seconds.

In the third scheme: the food processor is stopped when the swing direction of the food processor changes from vertical to horizontal. For example, when the food processor is operated, the swing direction is changed to be horizontal, and the operation is stopped.

A fourth scheme: the food processor swings in the direction from the positive position to the reverse position, and the work of the food processor is stopped. For example, when the food processor is operated, the swing direction is changed to be inverted, and the operation is stopped.

The fifth scheme is as follows: the food processor rotates horizontally and anticlockwise for one circle, and the food processor starts to work for a fixed time length.

The power of the handheld food processor is more valuable, and in order to save the power, the food processor in fig. 1 may have a power saving mode and a corresponding wake-up mode, for example, the control chip 5 may include a sleep module, the acceleration sensor 6 includes a wake-up module, and the wake-up module is connected to the sleep module; the dormancy module is used for controlling the control chip 5 to enter a dormancy state at the idle time of the food processor; and the awakening module is used for awakening the dormant state.

Some embodiments of the present application provide a schematic structural diagram of a part of a circuit of the food processor of fig. 1 in an application scenario, as shown in fig. 3, the part of the circuit can support a power saving mode and an awake mode.

In fig. 3, the left chip is used as the control chip 5, the right chip is used as the acceleration sensor 6, the acceleration sensor 6 is connected to the control chip 5 through an Inter-Integrated Circuit (IIC) interface, the control chip 5 can set the register parameter of the acceleration sensor 6 through the IIC interface, the acceleration sensor 6 transmits real-time acceleration sensing data to the control chip 5 through the IIC interface, and the two interrupt interfaces are used for waking up the sleep state of the control chip 5.

Based on the circuit in fig. 3, one triggering scheme of the power saving mode includes: when the food processor does not work for a period of time (for example, 20s), the control chip 5 automatically enters a power saving mode to save the electric quantity. One triggering scheme for the wake-up mode includes, for example: after the food processor is powered on for the first time, the control chip 5 carries out initialization setting on the acceleration sensor 6, and at the moment, besides setting basic parameters such as sampling frequency, communication rate, measuring range and the like, an interrupt awakening threshold value is also set; when the acceleration of the food processor exceeds the set interrupt wake-up threshold, the acceleration sensor will wake up the control chip 5, and at this time, the control chip 5 will immediately detect the user gesture operation.

Based on the power saving mode and the wake-up mode, some embodiments of the present application further provide a schematic workflow diagram of the food processor of fig. 1 in an application scenario, as shown in fig. 4.

The flow in fig. 4 includes the following steps:

electrifying and initializing the food processor, and entering a power saving mode if a user does not trigger; after the user shakes and wakes up, the food processing machine enters a working module, acceleration data starts to be collected, filtering processing is carried out, interference signals are filtered out and used for detecting gesture operation of the user, if the gesture operation of the user is not detected (for example, the gesture operation is judged to be not the user operation), the food processing machine enters a power saving mode, if the gesture operation of the user is detected (for example, the gesture operation is judged to be the user operation), the food processing machine is correspondingly controlled to work according to the gesture operation of the user, and the food processing machine enters the power saving mode. In the process, unnecessary electric quantity waste is reduced by entering the power saving mode in time, and the use of the gesture operation function of the user is better supported.
