[0048] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] This invention proposes a food processor.

[0051] Food processors include soy milk makers, blenders, and high-speed blenders—machines that use motors to pulverize food. Taking a high-speed blender as an example, its motor can reach speeds of over 25,000 rpm, instantly breaking down the cell walls of fruits and vegetables, thus effectively extracting phytochemicals. When using a food processor, the heating temperature, time, and program may vary depending on the ingredients. This requires users to manually select different blending cups and corresponding control programs based on the food being prepared, increasing the user's workload and complicating the food preparation process. Food processors typically consist of a cup and a base, with the motor located within the base. During operation, the motor in the base drives the blades inside the cup to rotate at high speed via a shaft. After blending, the cup and base can be separated. However, if the motor is accidentally triggered when the cup leaves the base, the rotating shaft could potentially cause injury. Therefore, a safety detection circuit is generally required to detect whether the cup assembly is properly placed on the base or to detect specific cup assemblies. The basic principle of current safety detection circuits is to set a safety switch in the circuit and a corresponding trigger device on the food processor. When the cup assembly is placed on the base, the safety switch closes or opens, and the detection circuit also closes or opens accordingly. The continuity of the detection circuit determines whether the cup assembly is on the base, ensuring that the motor only operates when the cup is inserted into the base, and stops when the cup is removed. Common safety switches used in food processors include mechanical microswitches, magnetic induction switches, and couplers. This method of preventing false triggering or identifying specific cup assemblies by detecting the continuity of the circuit requires a certain amount of installation space in the base, and each cup assembly needs a corresponding trigger device, making installation inconvenient, design complex, and costly.

[0052] To solve the above problems, refer to Figure 1 and Figure 2 In one embodiment of the present invention, the food processor includes:

[0053] Food container 10;

[0054] Base 20, on which a working position is provided for placing and fixing the cooking container 10;

[0055] The automatic clamping component 30 clamps the food container 10 when the food container 10 is placed on the base 20 in the working position.

[0056] The detection module 40, when the automatic clamping component 30 clamps the cooking container 10, contacts the cooking container 10 to form a detection circuit, so as to output the access electrical signal of the cooking container 10.

[0057] In one embodiment, the detection module 40 outputs an electrical signal indicating that the cooking container 10 is not connected when the automatic clamping component 30 fails to clamp the cooking container 10.

[0058] In this embodiment, the food preparation container 10, depending on its function, can be combined with the base 20 to form a high-speed blender, a blender, a juicer, or a soy milk maker. The high-speed blender can combine the functions of a juicer, soy milk maker, ice cream maker, food processor, and grinder, instantly breaking down food cell walls and releasing phytochemicals. The base 20 contains a motor. The food preparation container 10, depending on its function, may include a blending cup and blades within the blending cup, or simply a cup body with blades 11 embedded in the cup body and connected to the motor via a drive shaft, thus blending the food under the motor's drive. The blending cup has a cup body and a lid, the material of which can vary depending on the function. For example, when used for juicing, the cup body can be made of glass or plastic. When used for other functions such as soy milk makers requiring steaming or heating, the cup body can be made of metal or other easily heat-conducting composite materials. The material of the cup can vary depending on the ingredients being heated, enabling the food processor to perform various functions, such as heating, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. No limitations are imposed here. The shape of the lid can be selected as needed; in this embodiment, it can be round or square, and its material can be plastic, metal, or composite materials.

[0059] The base 20 includes a base housing 21 and a motor housed within the base housing 21. The base housing 21 has a groove, and the automatic clamping assembly 30 is disposed within the groove. A through hole is provided on the inner bottom wall of the groove, and a drive shaft passes through the through hole to connect the motor and the cutter 11. An electronic control board is also provided inside the base 20, and a detection module 40 is disposed on the electronic control board. The detection end of the detection module 40 can be connected to the automatic clamping assembly 30 via wires, a flexible substrate, etc.

[0060] The automatic clamping assembly 30 has both clamping and opening states. It clamps or releases the food container 10 by clamping or opening it radially. The automatic clamping assembly 30 is triggered by the food container 10. When the food container 10 is placed on the base 20, the automatic clamping assembly 30 is triggered and enters the clamping state. At this time, the food container 10 is axially clamped and fixed to the base 20 by the automatic clamping assembly 30, thus preventing relative movement between the food container 10 and the base 20. The automatic clamping assembly 30 can switch from the clamping state to the opening state based on the triggering of a microswitch. When the automatic clamping assembly 30 is in the opening state, the food container 10 is released, allowing the user to remove the food container 10 from the base 20 for operations such as pouring food or cleaning the food container 10. The automatic clamping assembly 30 can automatically clamp the food container 10, and can be disengaged by triggering a microswitch or other button when the user needs to remove it, thus preventing accidental scratches to the user and potential safety hazards.

[0061] The detection end of the detection module 40 is mounted on the automatic clamping assembly 30. When the cooking container 10 is placed on the base 20, it can come into contact with the cooking container 10 as the automatic clamping assembly 30 moves, thus forming a detection loop with the cooking container 10. After the detection loop is formed, an access electrical signal corresponding to the cooking container 10 is output. When the cooking container 10 is not placed on the base 20 or is removed from the base 20, the automatic clamping assembly 30 is in the open state and releases the clamp on the cooking container 10. The contact between the detection end of the detection module 40 and the cooking container 10 is also broken, and the detection loop with the cooking container 10 is broken. At this time, an access electrical signal is output.

[0062] This invention features a food preparation container 10 and a base 20. The base 20 has a designated working position for the food preparation container 10, allowing an automatic clamping component 30 to clamp the food preparation container 10 when it is placed in this position. Furthermore, the detection end of a detection module 40 is positioned on the automatic clamping component 30. When the automatic clamping component 30 clamps the food preparation container 10, it forms a detection circuit with the container, outputting an electrical signal indicating the container's connection. This invention determines whether the cup assembly is placed on the base 20 by checking the continuity of the detection circuit formed between the detection module 40 and the food preparation container 10, thus achieving safety detection and improving the safety of the food processor. This invention eliminates the need for a dedicated installation space for safety detection within the base 20, and the cup assembly does not require a corresponding triggering device, making installation convenient and reducing the production cost of the food processor.

[0063] Reference Figure 1 and Figure 2In one embodiment, the food processor further includes a main controller 50, which is electrically connected to the detection module 40.

[0064] In this embodiment, the main controller 50 can be implemented using a microprocessor such as a microcontroller, DSP, or FPGA. The main controller 50 is the control center of the food processor, connecting various parts of the food processor through various interfaces and lines. Specifically, the main controller 50 can integrate a comparator, memory, and data processor. By running or executing software programs and / or modules in the memory, and by calling stored data, it executes various functions of the food processor and processes data, thereby providing overall control of the food processor. The main controller 50 may include one or more processing units; preferably, the main controller 50 can integrate an application processor and a modem processor. The application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the main controller 50. In some embodiments, the food processor can also be equipped with a wireless communication circuit, such as a Bluetooth module, an infrared sensor module, or a WIFI module. The main controller 50 can also achieve wireless connection with mobile phones, smartwatches, etc., through the wireless communication module to receive control commands from applications and achieve wireless control of the food processor. Alternatively, it can send information such as the working status of the food processor to achieve human-machine interaction. The controller is mounted on the electronic control board and is electrically connected to the detection module 40. The main controller 50 can also be electrically connected to the motor drive module used to drive the motor to work, and control the working state of the motor according to the detection signal output by the detection module 40.

[0065] Reference Figure 1 and Figure 2 In one embodiment, the main controller 50 is used to confirm that the automatic clamping assembly 30 is not equipped with the cooking container 10 based on the non-connection electrical signal output by the detection module 40, and to output an alarm signal.

[0066] In this embodiment, when the main controller 50 outputs an electrical signal indicating that the food container 10 is connected according to the detection module 40, it can determine that the mixing cup is ready to be installed. The main controller 50 can then control the motor to start, thereby driving the blades 11 to rotate. When an electrical signal indicating that the food container 10 is not connected is detected, it can be confirmed before or during the operation of the food processor that the automatic clamping assembly 30 is not equipped with the food container 10. In this case, it can be determined that the mixing cup is not ready to be installed, and the main controller 50 will control the motor to stop working or stop working altogether. In one embodiment, an audible and visual alarm device, such as an LED light or a buzzer, can also be installed on the main control board or the base 20. When the main controller 50 confirms that the automatic clamping assembly 30 is not equipped with the food container 10, it will issue an alarm control signal to control the alarm device to work and output an alarm signal, thereby preventing user misoperation and alerting the user that the food processor is malfunctioning. This design ensures user safety, reduces the risk of personal injury due to misoperation, and improves the safety of the food processor.

[0067] Reference Figures 1 to 3 In one embodiment, the food processor further includes a heater 60, which is disposed on the base 20. The main controller 50 is used to identify the type of the food container 10 according to the electrical signal output by the detection module 40, and to control the heater 60 to work in a control mode corresponding to the identified type of food container 10.

[0068] In this embodiment, the heater 60 can be disposed on the bottom wall of the groove in the base 20, and a heat-conducting medium is disposed on the bottom plate of the blending cup. The heat-conducting medium includes at least one of metal (e.g., aluminum), ceramic, and glass. In another embodiment, the heater 60 can be an electromagnetic coil, and the bottom plate of the blending cup can be an electromagnetic heat-conducting plate, heating the food by electromagnetic heating. Of course, the bottom plate and side walls of the blending cup may not be equipped with heating devices such as electromagnetic coils, and the food may not be heated. The specific configuration depends on the function of the blending cup. For example, if it is used as a juicer, it may not need to be configured.

[0069] Specifically, when the heating element 60 uses an electromagnetic induction coil, an induction heating base corresponding to the electromagnetic induction coil is installed at the bottom of the mixing cup. In use, the electromagnetic induction coil is energized, generating an alternating magnetic field. Under the influence of this alternating magnetic field, the induction heating base cuts the alternating magnetic field lines, generating an alternating current, which in turn generates eddy currents. These eddy currents cause the atoms within the induction heating base to collide and rub against each other, generating heat energy, thereby heating the food in the mixing cup. Using this electromagnetic heating method to heat the mixing cup not only reduces maintenance and replacement costs, but also utilizes high-frequency electromagnetic heating, ensuring full heat utilization with minimal loss and very rapid heat start-up.

[0070] The heating element 60 heats the stirring cup using a heating method employing a resistance heating element or a heating film as the heat-conducting medium, with a heat-conducting plate correspondingly installed at the bottom of the stirring cup. Taking a heating element as an example, the heating element is generally fixed to the inner side of the bottom of the groove by die-casting. An aluminum alloy heat-conducting plate can also be installed at the bottom of the groove, with the heating element fixed on the aluminum alloy heat-conducting plate.

[0071] Reference Figure 1 and Figure 2 In one embodiment, the base 20 includes:

[0072] Base shell 21;

[0073] The power module 22 is disposed inside the base housing 21 and is electrically connected to the main controller 50. The main controller 50 is also used to control the power module 22 to work according to the identified type of the cooking container 10 and the control mode corresponding to the type of the cooking container 10.

[0074] In this embodiment, the power module 22 may include a motor and a drive shaft. The motor is controlled by the main controller 50, which has different function programs, such as making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Users can select different food containers 10. When the main controller 50 identifies different food containers 10, it calls the corresponding program to control the power module 22 and / or the heater 60 to achieve the corresponding function.

[0075] In practical applications, the main controller 50 can determine the motor's rotation duration, speed, and rotation cycle according to the type of the food processing container 10, so as to achieve different control modes. This allows it to work with different food processing containers 10 and execute corresponding cooking programs based on the type of the food processing container 10, eliminating the need for manual operation. This helps to improve the intelligence of the food processor and enhance its ease of use.

[0076] Reference Figure 1 and Figure 2 In one embodiment, the magnitude of the electrical signal output by the detection module 40 corresponds to the resistance value of the cooking container 10.

[0077] In this embodiment, the cup body of the food processor 10 can be made of different materials, each corresponding to a different resistance value. This resistance value can be a specific value or a range; in this embodiment, a range is selected. The main controller 50 can determine the type of cup body corresponding to the resistance value by the magnitude of the electrical signal. For example, if the main controller 50 detects that the resistance value is within the first resistance range, it determines that the food processor 10 is a blender cup; if it detects that the resistance value is within the second resistance range, it determines that the food processor 10 is a grinder cup; and if it detects that the resistance value is within the third resistance range, it determines that the food processor 10 is a juicer cup. When the main controller 50 detects and determines that the food processor 10 is a blender cup, it controls the food processor to execute a blending program to achieve the blending function; when it detects and determines that the food processor 10 is a grinder cup, it controls the food processor to execute a grinding program to achieve the grinding function; and when it detects that the food processor 10 is a juicer cup, it controls the food processor to execute a juicing program to achieve the juicing function. When executing the corresponding program, the main controller 50 can control whether the heater 60 heats, the heating temperature, the heating time, and the motor speed, rotation method (e.g., rotation direction), and rotation cycle. By controlling the operation of the heater 60 and the motor, the corresponding functions can be automatically achieved without manual operation by the user. It is understandable that due to different usage requirements, there may be situations where heating and stirring are needed simultaneously, or only heating is needed, or only stirring is needed, or neither heating nor stirring is needed. In such cases, depending on the type of cooking container 10, the heater 60 and the motor can be controlled to perform the corresponding function to meet the application requirements.

[0078] This invention can execute corresponding cooking programs according to the type of cooking container 10, without manual operation, which helps to improve the intelligence of the food processor and enhance its ease of use. The first resistance range, the second resistance range, and the third resistance range can be specifically determined according to the cooking container 10. Therefore, if the detected resistance value falls within one of these resistance ranges, the type of cooking container 10 corresponding to that resistance value can be determined.

[0079] Reference Figure 3 and Figure 4 In one embodiment, the detection module 40 has two detection parts disposed on the automatic clamping component 30. When the automatic clamping component 30 clamps the cooking container 10, the detection module 40 forms a detection circuit by contacting the cooking container 10 through the two detection parts, so as to output the access electrical signal of the cooking container 10.

[0080] In this embodiment, the two detection parts are disposed on the two clamping blocks 3333 of the automatic clamping assembly 30. When the automatic clamping assembly 30 does not clamp the cooking container 10, the two detection parts are essentially suspended in the air. When the automatic clamping assembly 30 clamps the cooking container 10, the two detection parts are connected to the cooking container 10. At this time, the cooking container 10 acts as a resistor. Under a constant voltage, the magnitude of the detected current value can determine the type of the cooking container 10. Alternatively, under a constant current, the magnitude of the detected voltage value can also determine the type of the cooking container 10.

[0081] Reference Figure 3 and Figure 2 In one embodiment, the food processor further includes a conductive heater 60, which is disposed on the automatic clamping assembly 30. When the automatic clamping assembly 30 clamps the food container 10, the conductive heater 60 contacts and connects with the food container 10.

[0082] The two detection sections of the detection module 40 are electrically connected to the conductive heater 60.

[0083] In this embodiment, the conductive heater 60 provides side heating. When the automatic clamping assembly 30 clamps the cooking container 10, the conductive heater 60 contacts and connects to the outer wall of the lower end of the cooking container 10. The conductive heater 60 can heat the cooking container 10 and also detect the type of the cooking container 10.

[0084] Correspondingly, a heat transfer plate 61 made of a heat-conducting medium is provided on the outer wall at the lower end of the mixing cup. The heat-conducting medium includes at least one of metal (e.g., aluminum), ceramic, and glass. The heat-conducting medium comes into thermal contact with the conductive heating element 60 to conduct heat and heat the food.

[0085] In another embodiment, the conductive heating element 60 can be an electromagnetic coil, and an electromagnetic heating plate is provided at the corresponding position of the blending cup to heat the food via electromagnetic heating. Of course, the side wall of the blending cup may not be equipped with an electromagnetic coil or other heating device, and the food may not be heated. The specific setting depends on the function of the blending cup. For example, if it is used as a juicer, it may not need to be set.

[0086] Specifically, when the conductive heater 60 uses an electromagnetic induction coil, an induction heating plate corresponding to the electromagnetic induction coil is installed on the outer wall of the mixing cup near the base 20. In use, the electromagnetic induction coil is energized, generating an alternating magnetic field. Under the influence of this alternating magnetic field, the induction heating plate cuts the alternating magnetic field lines, generating an alternating current, which in turn generates eddy currents. These eddy currents cause the atoms within the induction heating plate to collide and rub against each other, generating heat energy, thereby heating the food inside the mixing cup.

[0087] The conductive heater 60 heats the stirring cup using a heating method employing a resistance heating element or a heating film as the heat-conducting medium. A heat-conducting plate is correspondingly provided on the outer wall of the stirring cup near the base 20. Taking the heating element as an example, the heating element can be fixed to the inner side of the automatic clamping assembly 30 by die casting.

[0088] Reference Figure 3 and Figure 4 In one embodiment, the number of conductive heaters 60 is two;

[0089] The inner walls of the two conductive heaters 60 are arranged in an arc shape.

[0090] In this embodiment, the number of conductive heaters 60 can be one or two. When two are used, the two conductive heaters 60 are arranged opposite each other on both sides of the automatic clamping assembly 30. During heating, the main controller 50 can control one conductive heater 60 to work or control both conductive heaters 60 to work simultaneously, depending on the type of the cooking container 10. The inner walls of the two conductive heaters 60 are arc-shaped, forming a circle to clamp the cooking container 10, increasing the clamping force in the cooking container 10 and preventing the cooking container 10 from shaking in its radial direction. Arranging the inner walls of the two conductive heaters 60 in an arc shape also helps to increase the contact area between the conductive heaters 60 and the cooking container 10, thereby improving the heating efficiency.

[0091] Combined with reference Figure 1 and Figure 2 In one embodiment of the present invention, the clamping assembly 33 includes a carrier 331, at least two clamping members 333, and at least two connecting members 335. The carrier 331 is disposed at the working position of the base 20 and is used to support the base body 21. A clamping space for clamping the base body 21 is formed between the two clamping members 333. One end of a connecting member 335 is connected to the carrier 331, and the other end is connected to a clamping member 333. When the base body 21 is supported by the carrier 331, the connecting member 335 drives the two clamping members 333 to clamp the base body 21.

[0092] The support member 331 can be a plate-like structure used to support the lower end of the base body 21 in the cooking container 10. The clamping member 333 can be adapted to the shape of the base body 21, for example, the surface that fits against the base body 21 can be curved. When the base body 21 is placed on the support member 331, the weight of the base body 21 itself presses the support member 331 downward, thereby driving the connecting member 335 to move. The two connecting members 335 then drive the two clamping members 333 to move towards each other, thereby clamping the base body 21. In this way, the automatic clamping function can be completed by the weight of the base body 21 using only a mechanical transmission structure. When it is necessary to remove the base body 21, the base body 21 is taken out. Without the drive of the support member 331, the two clamping members 333 disengage from the base body 21, making it easier to remove the base body 21.

[0093] Furthermore, the connector 335 includes a bearing section 3351, a connecting section 3353, and a driving section 3355. One end of the bearing section 3351 is connected to the bearing member 331. One end of the connecting section 3353 is connected to the end of the bearing section 3351 opposite to the bearing member 331, and is arranged at an angle to the bearing section 3351. One end of the driving section 3355 is connected to the end of the connecting section 3353 opposite to the bearing section 3351, and the end of the driving section 3355 opposite to the bearing section 3351 is connected to the clamping member 333. The driving section 3355 and the connecting section 3353 are arranged at an angle.

[0094] The bearing section 3351 is connected to the bearing member 331, and a portion of the bearing section 3351 can be disposed outside the base 20. That is, the entire connecting member 335 can be disposed outside the base 20, and consequently, the entire clamping assembly 33 can be disposed outside the base 20, thus facilitating the installation and removal of the clamping assembly 33. Of course, it can also be as follows... Figure 1 and Figure 2 As shown, installation space is saved by passing a portion of the connector 335 through the base 20. The bearing section 3351 receives the downward driving force of the bearing 331 (refer to reference). Figure 1 The movement of the bearing section 3351, the connecting section 3353, and the driving section 3355 is directed by the movement of the connecting section 3353, which in turn drives the clamping member 333 to move laterally. The bearing section 3351, the connecting section 3353, and the driving section 3355 form a linkage structure, which drives the movement of the clamping member 333.

[0095] Furthermore, a first elastic element 35 is provided between the bearing member 331 and the base 20.

[0096] The first elastic element 35 enables the automatic reset function of the bearing element 331. The first elastic element 35 can be a spring or compression spring, or other structural components made of elastic material (such as an elastic silicone pad). When the base body 21 rests on the bearing element 331, the base body 21 presses against the bearing element 331, causing the first elastic element 35 to move downwards. When the base body 21 moves away from the bearing element 331, the first elastic element 35 elastically returns to its original position, causing the bearing element 331 to pull the connecting element 335, thus causing the two clamping elements 333 to move in opposite directions, thereby achieving the automatic release function of the clamping assembly 33.

[0097] In one embodiment of this application, the carrier 331 is further provided with a temperature sensor, which abuts against the base body 21 when the base body 21 is installed on the carrier 331.

[0098] Temperature sensors can monitor the temperature of the base body 21 in real time, thereby enabling intelligent processing control.

[0099] Further combined with reference Figure 1 and Figure 2 To facilitate the installation of the cooking container 10 and the base 20, as well as the installation of the clamping component 33 and the base 20, in one embodiment of the present invention, the base 20 is further provided with an installation groove 311. The installation groove 311 is formed as a working position. The support member 331 is installed on the bottom wall of the installation groove 311. The clamping member 333 is correspondingly provided with the side wall of the installation groove 311. One end of the connector 335 passes through the bottom wall of the installation groove 311 and is connected to the support member 331. The other end of the connector 335 passes through the side wall of the installation groove 311 and is connected to the clamping member 333.

[0100] When the base body 21 is installed on the base 20, a mounting groove 311 can be provided on the base 20 to make the placement of the base body 21 more stable. The mounting groove 311 serves as the mounting location for the clamping component 33 and is also the working position of the cooking container 10. When the base body 21 is installed into the mounting groove 311, the base body 21 presses against the bearing member 331 and moves downward toward the bottom wall of the groove. Then, the driving connector 335 drives the clamping member 333 to move laterally toward the side wall of the groove away from the mounting groove 311, thereby clamping the base body 21.

[0101] Combined with reference Figure 2 In one embodiment of the present invention, the clamping member 333 includes a mounting plate 3331 and a clamping block 3333. The mounting plate 3331 is connected to the connector 335, and the clamping block 3333 is disposed on the surface of the mounting plate 3331 opposite to the connector 335.

[0102] The mounting plate 3331 and clamping block 3333 make the installation and setup of clamping block 3333 simpler. The mounting plate 3331 and clamping block 3333 can be detachably connected, so that when clamping block 3333 is damaged, only the damaged clamping block 3333 needs to be replaced.

[0103] Furthermore, a second elastic element 3335 is provided between the mounting plate 3331 and the clamping block 3333. The second elastic element 3335 allows for a tighter contact between the clamping block 3333 and the base body 21, increasing the contact friction and thus making the base body 21 more stable. Simultaneously, the second elastic element 3335 also provides shock absorption. The second elastic element 3335 can be a spring or compression spring, or other structural components with elastic functions.

[0104] Or, the clamping block 3333 is a heating module, used to clamp the side surface of the cooking container 10. The clamping block 3333 has a heating function, allowing the cooking container 10 to be heated when installed on the base 20. This heating module can be a resistance heating module or an electromagnetic heating module, electrically connected to the main control board 37 inside the base 20 via wires. By setting the clamping block 3333 as a heating module, the heating element can be avoided on the base body 21, thereby reducing the weight of the base body 21 and simplifying the structure of the cooking container 10, making it convenient for users to use as a travel mug. The clamping block 3333 clamps laterally, while also providing heating, meaning heating can be achieved from the side of the base body 21. This side heating method further increases the heating area and improves heating efficiency.

[0105] Specifically, during the cup placement process, when a food container 10 is placed into the base 20, causing the support member 331 to move towards the base 20, the connecting end a, which is in contact with the support member 331, moves downward under the drive of the support member 331, while the connecting end b moves horizontally towards the axial direction of the food container 10, thereby driving the clamping block 3333 to move axially towards the food container 10 and locking the food container 10.

[0106] During the cup removal process, when the food container 10 is removed from the base 20, the carrier 331 can move away from the base 20 under the action of external forces such as buttons, and restore the initial height; the connecting end of the motion guide module 33 moves upward under the drive of the carrier 331, thereby driving the clamping block 3333 to move axially to the food container 10, releasing the food container 10 so that the user can remove the food container 10.

[0107] The present invention also proposes a control method for a food processor, applied to the food processor described above, the control method comprising:

[0108] When the automatic clamping component 30 of the food processor clamps the food processor container 10, the detection module 40 of the food processor contacts the food processor container 10 to form a detection circuit, so as to output the access electrical signal of the food processor container 10.

[0109] The type of the food processor's food container 10 is identified based on the access electrical signal, and the heating element 60 and / or the power module 22 of the food processor are controlled to operate in a control mode corresponding to the type of the food processor's food container 10.

[0110] This invention features a food preparation container 10 and a base 20. The base 20 has a designated working position for the food preparation container 10, allowing an automatic clamping component 30 to clamp the food preparation container 10 when it is placed in this position. Furthermore, the detection end of a detection module 40 is positioned on the automatic clamping component 30. When the automatic clamping component 30 clamps the food preparation container 10, it forms a detection circuit with the container, outputting an electrical signal indicating the container's connection. This invention determines whether the cup assembly is placed on the base 20 by checking the continuity of the detection circuit formed between the detection module 40 and the food preparation container 10, thus achieving safety detection and improving the safety of the food processor. This invention eliminates the need for a dedicated installation space for safety detection within the base 20, and the cup assembly does not require a corresponding triggering device, making installation convenient and reducing the production cost of the food processor.

[0111] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
