Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a heating mixer. Background Technology

[0002] In conventional heating and blending products, each machine is typically designed for a single function, either providing both heating and blending capabilities or only offering room-temperature blending. If a user needs both heating and cooking and room-temperature blending, they often need to purchase two separate units, which not only takes up kitchen space but also increases the purchase cost.

[0003] Some products attempt to expand functionality by equipping the same main unit with interchangeable cups, but this design presents significant safety hazards. If a user mistakenly installs a heat-sensitive or non-heat-resistant room-temperature blending cup onto a main unit with a heating function, the main unit may not recognize the cup type and could still output heating power to the cup. This can easily cause the cup material to deform due to high temperatures, release harmful substances, or even lead to a fire or damage to the appliance. Furthermore, even if users clearly understand the purpose of different cups, they may easily forget to manually switch function modes when frequently switching between them, resulting in misoperation.

[0004] Therefore, how to ensure that a single host can be compatible with multiple types of cups while accurately identifying the type of cup currently installed and automatically deciding whether to enable the heating function based on the type of cup, thereby eliminating safety hazards caused by misuse of cups or incorrect mode selection, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To address the aforementioned shortcomings, this invention proposes a heating mixer that distinguishes between open heating cups and closed mixing cups and automatically matches the corresponding working modes using an identification module. This achieves dual-cup compatibility in one machine, balancing multi-functional usage needs with electrical safety.

[0006] The present invention provides the following technical solution: a heating mixer, comprising a main unit, a blade holder and a cup body, wherein the cup body comprises an open heating cup and a closed mixing cup; The blade holder and the main unit are detachably locked via a screw-in structure. The blade holder is equipped with a stirring blade assembly, which can be inserted into the cup body. The main unit has an identification module to detect whether the cup that mates with the blade holder is an open heating cup or a closed mixing cup. When it is identified as an open heating cup, the main unit activates the heating and mixing modes. When it is identified as a closed mixing cup, the main unit disables the heating function and only executes the mixing mode.

[0007] Compared with the prior art, the advantages of the present invention are as follows: This technical solution divides the cup into an open heating cup and a closed mixing cup, and incorporates a recognition module within the main unit, enabling the same heating and mixing machine to be compatible with both types of cups. When the open heating cup is installed, the main unit automatically activates the heating and mixing modes, allowing for the heating and blending of ingredients. When the closed mixing cup is installed, the main unit automatically disables the heating function, performing only the mixing mode. Thus, a single machine can meet both heating and cooking needs and room-temperature mixing requirements, eliminating the need to purchase two separate devices or manually switch between functions.

[0008] The identification module can automatically detect the type of cup currently mating with the blade holder and determine whether to allow the heating function to be enabled based on the detection results. This fundamentally avoids the safety hazards caused by users misusing a sealed mixing cup as a heating cup due to misoperation or negligence, and also prevents the risk of fire or appliance damage caused by mistakenly heating a cup that is not equipped for heating, significantly improving the safety of product use.

[0009] Whether the heating function is enabled or not is automatically determined by the recognition module based on the cup type, eliminating the need for users to manually select heating or stirring modes on the control panel. This simplifies the operation process, lowers the barrier to entry, and enhances the product's intelligence and user experience.

[0010] As an improvement, a cup-state detection component is also included to cooperate with the identification module. This component includes a signal triggering unit on the cup body, a signal acquisition unit inside the tool holder, and a signal transmission interface between the tool holder and the host computer. When the tool holder and host computer are screwed in and locked, and the cup body is in a preset working state, the signal triggering unit drives the signal acquisition unit to generate a sensing signal. This signal is then fed back to the host computer via the signal transmission interface, allowing the identification module to identify the cup type. Through the coordinated operation of the signal triggering unit, signal acquisition unit, and signal transmission interface, a complete detection link from the cup body to the host computer is established. Only when both conditions are met—the tool holder and host computer being screwed in and locked, and the cup body being in a preset working state—will the signal triggering unit drive the signal acquisition unit to generate a sensing signal, which is then fed back to the host computer via the signal transmission interface for identification by the identification module. The cup type identification ensures accuracy and reliability, preventing misidentification due to improper installation or the cup not being in the preset working state. The signal trigger and signal acquisition sections are located on the cup and the cutter holder, respectively, eliminating the need for direct cable connection. Instead, a physical trigger generates a sensing signal, preventing cable tangling or terminal wear when removing the cup from the cutter holder, facilitating cup replacement and cleaning. The signal transmission interface is located between the cutter holder and the main unit, reliably transmitting the sensing signal from the cutter holder to the main unit. This clear division of labor between signal acquisition and transmission, with each interface fulfilling its corresponding function, reduces the complexity of overall wiring. The entire signal acquisition and transmission process is automatically triggered by the cutter holder screwing in and locking, and the cup's preset working state. Users can automatically identify the cup type without additional operation, simplifying the usage process.

[0011] It also includes a screw-in coupling protection assembly that works with the identification module. The main unit has a first coupling terminal with a protective element, and the tool holder has a second coupling terminal. During the screw-in locking process between the tool holder and the main unit, the tool holder drives the protective element to shift, causing the first coupling terminal to switch from a shielded state to an exposed state, thereby achieving a screw-in electrical connection with the second coupling terminal. The identification module determines whether the tool holder is installed correctly by detecting the on / off state of the electrical signals of the first and second coupling terminals, so as to realize power transmission and signal transmission. Before the tool holder is screwed in and locked, the protective element keeps the first coupling terminal in a shielded state to prevent dust, liquid, or foreign objects from entering the terminal area; when the tool holder is screwed in and locked, the tool holder drives the protective element to shift. When the component shifts, the first coupling terminal switches from a shielded state to an exposed state, and then completes a screw-in electrical connection with the second coupling terminal. The opening of the protective component and the connection of the terminal are automatically triggered by the screwing-in action of the tool holder, eliminating the need for the user to manually open the protective cover or perform a separate plugging action, simplifying the operation steps and realizing the linkage function of locking and connecting. The identification module determines whether the tool holder is installed in place by detecting the on / off state of the electrical signals of the first and second coupling terminals. Only when the two coupling terminals are in physical contact and form a conductive circuit will the identification module confirm that the tool holder has been locked in place. This determination method is directly based on the physical state of the electrical connection, has high reliability, and is not affected by environmental factors.

[0012] As an improvement, a signal connection component is also provided between the tool holder and the main unit. This component is configured to: synchronously connect when the tool holder and main unit are screwed into place via a screw-in mechanism, allowing the identification module to receive the sensing signal from the cup-state detection component; when the tool holder is not screwed in, the signal connection component is disconnected, blocking the signal path between the cup-state detection component and the main unit's identification module; when the tool holder is screwed in and locked in place, the signal connection component is synchronously connected, instantly establishing a signal transmission path, allowing the identification module to receive the sensing signal from the cup-state detection component. Thus, the signal connection and mechanical locking are synchronized, eliminating the need for additional user wiring.

[0013] As an improvement, the tool holder includes an outer ring and an inner ring located radially inward of the outer ring. The inner ring has a terminal mounting position, and at least a portion of the signal engagement assembly is located within the terminal mounting position. A connector extends radially from the inner wall of the outer ring, and the connector is fixedly connected to the component within the terminal mounting position. This allows the outer ring to synchronously drive the component to rotate and engage with the corresponding interface on the host computer when the tool holder rotates as a whole. When the tool holder rotates as a whole, the rotational torque of the outer ring is directly transmitted to the component within the terminal mounting position via the connector, causing the component to rotate synchronously with the tool holder until it accurately engages with the corresponding interface on the host computer. Therefore, the screwing-in locking action of the tool holder and the activation action of the signal engagement assembly are completely synchronized in space and time, eliminating the need for a separate drive mechanism or additional operating steps for the signal engagement assembly.

[0014] As an improvement, a heating element is integrated within the inner ring, arranged circumferentially along the inner ring. The heating element is electrically connected to a second coupling terminal, obtaining operating power through a connection circuit between the first and second coupling terminals. The cup body itself does not require a separate heating element to achieve heating, simplifying the cup's structural design, reducing manufacturing and maintenance costs, and facilitating cleaning and replacement with cups of different functions. The circumferential arrangement of the heating element provides surround heating of the food inside the cup, with heat evenly transferred upwards from the bottom of the cup, reducing localized overheating or uneven heating and improving the consistency and texture of food processing. The heating element's electrical connection to the second coupling terminal obtains operating power through a connection circuit between the first and second coupling terminals. This makes the power supply path of the heating element directly related to the screw-in coupling protection component. The heating element can only be powered when the tool holder is screwed in and locked in place, and the first coupling terminal and the second coupling terminal are engaged to form a conductive circuit. When the tool holder is not locked, the coupling terminal is in the open state, and the heating element cannot be powered. This prevents the safety hazard of accidental power supply and heating in the state of false locking from the perspective of electrical structure.

[0015] As an improvement, the protective component includes a driven part and a shielding part. In the shielded state, the shielding part blocks the electrical connection path of the first coupling terminal, and the driven part is located within the area covered by the screw-in motion trajectory of the tool holder. When the tool holder is screwed in and locked, the tool holder abuts against the driven part to drive the entire protective component to move, causing the shielded area to move away from the electrical connection path, exposing the first coupling terminal. In the shielded state, the shielding part blocks the electrical connection path of the first coupling terminal, preventing foreign objects such as dust and liquid from entering the terminal area. The driven part is located within the area covered by the screw-in motion trajectory of the tool holder and is in a ready position to receive the drive of the tool holder. When the tool holder is screwed in and locked, the tool holder directly abuts against the driven part, driving the entire protective component to move. The shielding part then moves away from the electrical connection path, exposing the first coupling terminal, which then completes an electrical connection with the second coupling terminal.

[0016] As an improvement, the screw-in coupling protection assembly also includes a resilient reset member corresponding to the protective component. The resilient reset member is configured to continuously apply a biasing force to the protective component, keeping it in a shielded state. When the tool holder is screwed in and locked, the tool holder overcomes the biasing force to resist the driven part, driving the protective component to move. After the tool holder is screwed out, the biasing force drives the protective component back to the shielded state. In the non-use state, the protective component remains stably sealed on the electrical connection path of the first coupling terminal under the action of the biasing force, preventing accidental opening due to tilting, vibration, or transportation bumps, ensuring the long-term reliability of the protection. When the tool holder is screwed in and locked, the tool holder needs to overcome the biasing force of the resilient reset member to push the driven part to drive the protective component. The presence of the biasing force provides a moderate damping feel during the screw-in operation, allowing the user to perceive by hand that the protective component is being driven open. When the tool holder is screwed out, the resistance force of the tool holder against the driven part disappears, the biasing force accumulated in the resilient reset member is released instantaneously, and the protective component is automatically driven back to the shielded state. The entire reset process requires no manual operation of the protective cover by the user, nor does it rely on any reset mechanism other than gravity or springs, achieving a reliable response of automatic protection upon unlocking.

[0017] As an improvement, a first magnetic trigger element is provided on the outer wall of the sealed mixing cup near the opening end as a signal triggering part. A magnetic induction signal detection switch, which is inductively coupled with the first magnetic trigger element, is provided inside the blade holder as a signal acquisition part. When the sealed mixing cup is installed on the blade holder and the handle is locked, the first magnetic trigger element triggers the signal detection switch, causing the host to determine that the current load is a sealed mixing cup and allowing the heating element inside the blade holder to be turned off. When the sealed mixing cup is installed on the blade holder and the handle is locked, the first magnetic trigger element and the magnetic induction signal detection switch are spatially close and aligned. The magnetic field triggers the detection switch to generate an induction signal, which the host uses to determine that the current load is a sealed mixing cup and allows the heating element inside the blade holder to be turned off. Thus, the identification of the sealed mixing cup and the handle locking action are combined into one, eliminating the need for the user to perform an additional signal triggering step during normal operation. The magnetic trigger element and the magnetic induction signal detection switch use a non-contact induction coupling, eliminating mechanical contact wear or oxidation issues. The signal triggering is stable and reliable, maintaining consistent sensitivity even after long-term use.

[0018] As an improvement, the handle of the open-ended heating cup is equipped with a movable linkage as a signal trigger, and the tool holder is equipped with a signal detection switch as a signal acquisition unit. When the open-ended heating cup is installed on the tool holder and the handle is locked, the movable linkage is pressed and triggers the signal detection switch, causing the host to determine that the current load is the open-ended heating cup and allow the heating element in the tool holder to be turned on. When the open-ended heating cup is installed on the tool holder and the handle is locked, the movable linkage is pressed and triggers the signal detection switch, generating an induction signal that is fed back to the host. Thus, the locking action of the handle and the signal triggering action are combined into one, eliminating the need for the user to perform an additional signal triggering step during normal operation, simplifying the usage process. The locked state of the handle directly determines... Whether the signal detection switch is triggered or not, no signal will be generated if the handle is not locked. The main unit cannot determine that the current load is an open-faced heating cup, and therefore will not connect the heating element inside the blade holder. This forcibly links the activation of the heating function to the correct locking of the handle, avoiding safety hazards caused by the cup becoming loose or tilted during operation due to an unlocked handle, and preventing accidental heating when the cup is not reliably secured. The signal triggering and signal acquisition parts are located inside the handle and blade holder, and the two are triggered by mechanical action. There is no need for exposed electrical contacts or cable connections between the cup and the blade holder, so that cable tangling or terminal wear will not occur when the cup is removed from the blade holder, facilitating cleaning and replacement of the cup. The connection of the heating element is only permitted after the identification module determines that the cup type is an open-faced heating cup. Therefore, the heating function is only allowed to be activated under the dual conditions of hardware triggering and software identification, further improving the safety of product use.

[0019] As an improvement, the lid of the open-top heated cup is equipped with a magnetic trigger element as a signal trigger, and the blade holder is equipped with a reed switch that engages with the magnetic trigger element as a signal acquisition unit. The signal transmission interface includes a probe assembly located at the bottom of the blade holder. When the lid is closed and locked, the reed switch closes under magnetic force, and the induction signal is fed back to the host through the probe assembly, allowing the host to determine that the current load is an open-top heated cup. When the lid is closed and locked, the magnetic trigger element approaches the reed switch, and the reed switch closes under magnetic force, generating an induction signal. When the lid is not closed or locked, the distance between the magnetic trigger element and the reed switch is insufficient to trigger the closure, and no signal is generated. This non-contact magnetic induction triggering method eliminates the problems of mechanical wear or contact oxidation, ensuring stable and reliable signal triggering and maintaining consistent sensitivity over long-term use. The closed and locked state is the only condition for generating an induction signal. Only upon receiving this sensing signal can the current load be determined to be an open heating cup, thus allowing the subsequent heating function to be activated. If the cup lid is not properly closed or locked, the reed switch remains open, the main unit cannot obtain a cup type confirmation signal, and the heating function cannot be started. Therefore, the safety operation of closing and locking the lid is forcibly embedded in the electrical control logic, preventing the risk of food splashing or accidental user contact with the blade caused by the high-speed rotation of the motor when the lid is not closed. It also avoids the safety hazard of steam or hot liquid overflowing due to the lid not being locked during heating. The signal transmission interface uses a probe assembly located at the bottom of the blade holder to transmit the sensing signal from the blade holder to the main unit. The probe assembly automatically presses and conducts during the process of screwing the blade holder and the main unit into place and locking, eliminating the need for manual alignment or cable connection by the user. The establishment of the signal transmission path is completed synchronously with the mechanical locking of the blade holder, simplifying the operation steps and improving the reliability of signal transmission.

[0023] like Figures 1 to 15 As shown in the figure, this solution provides a heating mixer, the structure of which is as follows.

[0024] The heating mixer comprises three main parts: a main unit 1, a blade holder 2, and a cup body. The main unit 1 serves as the support and power / control core of the entire machine, with a mounting base 1.1 on its upper part. Multiple insertion portions 1.1.1 are distributed circumferentially on the outer wall of the mounting base 1.1, each protruding radially outward. Inside each insertion portion 1.1.1, a second high-voltage terminal coupler 4 and a terminal protection member 5 are accommodated, with a dustproof portion formed on the terminal protection member 5. A limiting portion 1.1.2 is also provided at the rear end of each insertion portion 1.1.1 along the screw-in direction of the blade holder 2. After assembly, the radial outer wall of the insertion portion 1.1.1 and the radial inner wall of the blade holder 2 form a sliding groove 11.

[0025] The blade holder 2 connects the main unit 1 and the cup body, and its lower end is machined with a mounting groove 2.1. A first high-voltage terminal coupler 6 is installed inside the mounting groove 2.1. Three first high-voltage terminal couplers 6 are provided, corresponding to grounding, neutral, and live wire functions respectively, to meet the high-voltage power supply requirements of the heating coil 8 and the motor, etc. A retaining block 2.2 is provided on the side wall of the mounting groove 2.1. The main structure of the blade holder 2 includes an outer ring portion 2.3 located on the outer side and an inner ring portion 2.4 located radially inward of the outer ring portion 2.3. A heating coil 8 is integrated inside the inner ring portion 2.4, which is arranged circumferentially around the inner ring portion 2.4 and can be used to heat the food inside the cup body. The aforementioned mounting groove 2.1 is located radially inward of the inner ring portion 2.4. A first low-voltage terminal coupler 9 is also provided inside the mounting groove 2.1, and a second low-voltage terminal coupler 10 is correspondingly provided inside the main unit 1 mounting base 1.1, for transmitting control signals or sensor signals. To achieve motion transmission, a connector 2.5 extends radially inward from the inner wall of the outer ring 2.3. A high-voltage socket is formed on the connector 2.5 corresponding to the position of the first high-voltage terminal coupler 6, and a low-voltage socket is formed corresponding to the position of the first low-voltage terminal coupler 9. The high-voltage socket is fitted onto the first high-voltage terminal coupler 6, and the low-voltage socket is fitted onto the first low-voltage terminal coupler 9. This allows the rotational motion of the outer ring 2.3 to be synchronously transmitted to the first high-voltage terminal coupler 6 and the first low-voltage terminal coupler 9 via the connector 2.5 and the sockets, enabling each terminal to rotate integrally with the tool holder 2. The first low-voltage terminal coupler 9 and the second low-voltage terminal coupler 10 are configured to achieve contact coupling through rotational action; that is, when the tool holder 2 and the main unit 1 are screwed and locked in place, they become conductive through rotational contact.

[0026] Regarding the specific structure of the terminal protection member 5, a first insertion groove 1.1.3 is provided at one end of the insertion portion 1.1.1 away from the limiting portion 1.1.2, and the terminal protection member 5 is disposed inside the insertion portion 1.1.1. A second insertion groove 5.2 is provided at the front end of the terminal protection member 5, and the second insertion groove 5.2 is axially opposite to the first insertion groove 1.1.3. A second high-voltage terminal coupler 4 is fixedly disposed in the internal space of the terminal protection member 5 and forms an insertion gap 4.1, which is opposite to both the first insertion groove 1.1.3 and the second insertion groove 5.2. The dustproof part on the terminal protection member 5 specifically includes a first dustproof part 5.3 and a second dustproof part 5.4, which are respectively disposed on the radial sides of the second insertion groove 5.2, with the first dustproof part 5.3 located on the outer side and the second dustproof part 5.4 located on the inner side. When the terminal protector 5 is in the protected position, at least a portion of the first dustproof part 5.3 extends into the sliding groove 11, while the second dustproof part 5.4 seals the gap 4.1 between the first insertion groove 1.1.3 and the second high-voltage terminal coupler 4, thus shielding and protecting the insertion gap 4.1. When the tool holder 2 is screwed and locked into place with the main unit 1, and the terminal protector 5 is pushed to the connected state, the terminal protector 5 moves radially inward, aligning and connecting the first insertion groove 1.1.3, the second insertion groove 5.2, and the insertion gap 4.1 to form a continuous insertion space, allowing the first high-voltage terminal coupler 6 to be smoothly inserted and complete the electrical connection.

[0027] To achieve automatic reset of the terminal protection component 5, several sets of screw-in coupling protection components are distributed circumferentially within the mounting base 1.1. The terminal protection component 5 and the elastic component 7 together constitute the screw-in coupling protection components. The terminal protection component 5 is the protective component, and the elastic component 7 is the elastic reset component. The driven part of the protective component is the first dustproof part 5.3 of the terminal protection component 5, and the shielding part of the protective component is the second dustproof part 5.4 of the terminal protection component 5. The first high-voltage terminal coupler 6 is the first coupling terminal, the second high-voltage terminal coupler 4 is the second coupling terminal, and the signal bonding assembly includes a first low-voltage terminal coupler 9 and a second low-voltage terminal coupler 10. The terminal protection component 5 is provided with an abutment part 5.1, which is located close to its corresponding elastic component 7. A mounting post is provided within the mounting base 1.1 corresponding to the elastic component 7. The elastic component 7 includes a sleeve portion fitted onto the outer peripheral wall of the mounting post and an elastic arm extending from the tail end of the sleeve portion towards the abutment part 5.1. The elastic arm continuously applies a biasing force to the abutment portion 5.1 of the corresponding terminal protection member 5, and the direction of this biasing force keeps the terminal protection member 5 stably in the protected position. During the process of screwing and locking the tool holder 2 with the main unit 1, the locking block 2.2 on the tool holder 2 will overcome the biasing force of the elastic arm and push the terminal protection member 5 away from the protected position; when the tool holder 2 is unlocked and separated from the main unit 1, the biasing force will drive the terminal protection member 5 to automatically reset, so that the dustproof part will once again cover the second high-voltage terminal coupler 4.

[0028] The cup body is used to hold the food to be processed, and its end facing the blade holder 2 has an open end. The stirring blade assembly 3 is fixedly installed on the blade holder 2. After the cup body is connected to the blade holder 2, the stirring blade assembly 3 enters the interior of the cup body through the open end and rotates under the drive of the motor to achieve functions such as stirring and pulverizing. Depending on the usage requirements, the cup body can be configured in two structural forms. First, the cup body is a closed stirring cup 12, which is integrally formed, and its open end is detachably connected to the outer ring 2.3 by threads. Second, the cup body is a combination of an open heating cup 13 and a cup lid 14. The cup lid 14 can cover the upper end of the open heating cup 13, and the two are detachably connected by a snap-fit ​​structure. The lower end of the open heating cup 13 is machined with an open end, which is also connected to the outer ring 2.3 by threads. Both of these cup body forms are secured to the blade holder 2 by threads locking the open end to the outer ring 2.3 of the blade holder 2, so that the entire cup body is firmly fixed to the blade holder 2.

[0029] During assembly, the user first installs the cup body onto the blade holder 2. If a closed stirring cup 12 is used, the open end of the closed stirring cup 12 is aligned with the outer ring 2.3 of the blade holder 2 and tightened by thread to form a detachable sealed connection between the cup body and the blade holder 2. If a combination of an open heating cup 13 and a cup lid 14 is used, the open end of the lower end of the open heating cup 13 is first tightened by thread with the outer ring 2.3 of the blade holder 2, and then the cup lid 14 is fastened to the upper end of the open heating cup 13 by a snap-fit ​​structure. After the cup body is installed, the stirring blade assembly 3 enters the cup body through the open end. Subsequently, the user installs the assembled blade holder 2 together with the cup body onto the main unit 1. The mounting groove 2.1 at the lower end of the blade holder 2 is aligned with the mounting base 1.1 of the main unit 1, and the locking block 2.2 in the mounting groove 2.1 is aligned with the gap between two adjacent insertion parts 1.1.1 on the mounting base 1.1. At this time, each terminal protection member 5 is held in the protected position under the bias pressure of the corresponding elastic arm, at least a part of the first dustproof part 5.3 extends into the sliding groove 11, the second dustproof part 5.4 is sealed between the first insertion groove 1.1.3 and the insertion gap 4.1, and the second high-voltage terminal coupler 4 is in a shielded and protected state.

[0030] Regarding cup state detection, a first magnetic trigger element 12.1 is provided on the outer wall of the sealed stirring cup 12 near the opening end as a signal triggering part. A magnetic induction signal detection switch 2.6 is provided inside the knife holder 2 as a signal acquisition part. The magnetic induction signal detection switch 2.6 and the first magnetic trigger element 12.1 are spatially opposite to each other when the sealed stirring cup 12 is installed in place.

[0031] When using the open-ended heating cup 13, with the handle movable link 13.1 as the signal trigger, the outer wall of the open-ended heating cup 13 is provided with a handle, and the handle contains the movable link 13.1 as the signal trigger. The movable link 13.1 is in a free state when the handle is in the unlocked position. When the handle is gripped and rotated or pressed to the locked position by the user, the movable link 13.1 is pressed downwards. The tool holder 2 contains a plug-in signal detection switch 2.7 as a signal acquisition unit, with the trigger end of the plug-in signal detection switch 2.7 facing the installation direction of the handle. The bottom of the tool holder 2 is provided with a probe assembly as a signal transmission interface.

[0032] When using the open heating cup 13 and the magnetic trigger element of the cup lid 14 as the signal trigger, a second magnetic trigger element is provided inside the cup lid 14 as the signal trigger. The second magnetic trigger element is embedded in the edge of the cup lid 14 or near the buckle. A reed switch is provided inside the blade holder 2 as the signal acquisition unit. The reed switch and the second magnetic trigger element are spatially opposite each other when the cup lid 14 is in the closed and locked state. A probe assembly is provided at the bottom of the blade holder 2 as a signal transmission interface.

[0033] When the user begins to rotate the tool holder 2, the locking block 2.2 rotates together with the tool holder 2 and enters the sliding groove 11 formed by the radial outer wall of the insertion part 1.1.1 and the radial inner wall of the tool holder 2, sliding along the predetermined track of the sliding groove 11. During this engagement process, the locking block 2.2 first contacts the first dustproof part 5.3 located in the sliding groove 11, and as the rotation continues, it pushes the entire terminal protection member 5, overcoming the biasing force applied by the elastic arm, causing the terminal protection member 5 to move radially inward. At this time, the second dustproof part 5.4 moves away from the first insertion groove 1.1.3 and the insertion gap 4.1, and the first insertion groove 1.1.3, the second insertion groove 5.2 and the insertion gap 4.1 are aligned and connected, forming a continuous insertion space, and the terminal protection member 5 enters the connected state. Simultaneously, the rotational movement of the outer ring 2.3 is transmitted synchronously to the first high-voltage terminal coupler 6 and the first low-voltage terminal coupler 9 through the connector 2.5 and the high-voltage and low-voltage sockets, causing each terminal to rotate as a whole with the tool holder 2. When the first high-voltage terminal coupler 6 rotates to align with the insertion space, it enters the insertion gap 4.1 through the first insertion slot 1.1.3 and the second insertion slot 5.2, completing the insertion connection with the second high-voltage terminal coupler 4, and connecting the ground, neutral, and live wire circuits respectively. The first low-voltage terminal coupler 9 also contacts the second low-voltage terminal coupler 10 during the rotation, achieving contact coupling and conduction. When the rear end of the locking block 2.2 finally abuts against the inner wall of the limiting part 1.1.2 at the rear end of the insertion part 1.1.1, the locking block 2.2 is reliably stopped in circumferential movement, and the tool holder 2 cannot continue to rotate, indicating that the locking is in place. At this time, the mechanical locking of the tool holder 2 and the electrical connection of the high-voltage and low-voltage circuits are completed in the same rotation operation.

[0034] At this time, the first magnetic trigger element 12.1 on the closed stirring cup 12 triggers the magnetic induction signal detection switch 2.6 in the blade holder 2 to generate an induction signal, which is fed back to the host 1 via the probe assembly. The identification module determines that the current load is the closed stirring cup 12 based on the induction signal and disables the heating function, allowing only the stirring mode to operate. Although the heating coil 8 has a power input path, the host 1 does not output heating power to it.

[0035] When using the open-top heating cup 13, with the handle linkage 13.1 as the signal trigger, the user rotates or presses the handle to the locked position. The linkage 13.1 is displaced under pressure, and its end contacts and triggers the plug-in signal detection switch 2.7, generating a sensing signal. The sensing signal is fed back to the identification module in the main unit 1 via the probe assembly. The identification module determines that the current load is the open-top heating cup 13 based on the sensing signal and allows the heating coil 8 to be connected. The heating coil 8 obtains working power through the connection circuit of the first high-voltage terminal coupler 6 and the second high-voltage terminal coupler 4, and heats the food in the cup in a circumferential manner along the inner ring 2.4. The motor drives the stirring blade assembly 3 to rotate and stir. When the user needs to stop heating or disassemble the cup, the handle is released from the locked position, the linkage 13.1 is reset, the plug-in signal detection switch 2.7 is disconnected, and the main unit 1 automatically stops heating after recognizing the disappearance of the signal.

[0036] When using the open-top heated cup 13, with the magnetic trigger element of the cup lid 14 as the signal trigger, the second magnetic trigger element inside the cup lid 14 rotates with the cup lid 14 until it approaches and aligns with the reed switch inside the blade holder 2 in the vertical direction. The reed switch closes under magnetic force, generating an induction signal. After the blade holder 2 is locked in place, the probe assembly is pressed and connected to the interface of the main unit 1. The induction signal is fed back to the identification module inside the main unit 1 through the probe assembly. The identification module determines that the current load is the open-top heated cup 13 based on the induction signal, activates the heating and stirring mode, and allows power to be supplied to the heating coil 8.

[0037] If the cup lid 14 is not properly closed or locked, the distance or angular deviation between the second magnetic trigger element and the reed switch is insufficient to trigger the reed switch to close, and the sensing signal cannot be generated. After the blade holder 2 is locked in place, the main unit 1 cannot detect the sensing signal, cannot confirm the cup type, and the heating function remains disabled, preventing the risk of food splashing or accidental user contact with the blade head caused by the motor rotating at high speed when the cup lid 14 is not closed.

[0038] When the user needs to disassemble, clean, or replace parts, simply rotate the tool holder 2 in the reverse direction. The locking block 2.2 separates from the limiting part 1.1.2 and slides out along the sliding groove 11 in the reverse direction. During the process of the locking block 2.2 exiting the sliding groove 11, the pushing force of the locking block 2.2 on the first dustproof part 5.3 disappears, the bias pressure accumulated in the elastic arm is released, and the driving terminal protection part 5 moves radially outward and automatically resets to the protection position. At this time, the first dustproof part 5.3 extends back into the sliding groove 11, and the second dustproof part 5.4 re-seals between the first insertion groove 1.1.3 and the insertion gap 4.1, completely blocking the second high-voltage terminal coupler 4. The user continues to rotate the tool holder 2 in the reverse direction until the locking block 2.2 completely exits the sliding groove 11, and the tool holder 2 and its body can be removed from the main unit 1 to complete the disassembly. The entire process of unlocking and protection is automatically synchronized, without the need for the user to manually operate the protective cover or separately plug and unplug the terminals, simplifying the operation steps.
