Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a portable food processing machine. Background Technology

[0002] Existing food processors, such as high-speed blenders, typically consist of a separate main unit and a blending cup assembly. The main unit contains a motor, and the blending cup assembly contains pulverizing blades. Users attach the blending cup assembly to the main unit, and the motor drives the pulverizing blades to pulverize the ingredients. However, this type of product is generally only suitable for home use. As users expand their usage, there is a growing demand for portable food processors that can be used while traveling.

[0003] Based on the above needs, existing technologies have miniaturized food processing machines to make them easier for users to carry. In its research on technical directions, the applicant proposed two technical directions: the cup body and the base are integrated, and the cup body and the base are detachable.

[0004] For example, the applicant's earlier patent application CN202022707521.4 discloses a food processor, including an integrally formed cup body and main unit. To ensure more stable and reliable operation during heating, a cup lid with a lower cover and an upper cover is provided. The lower cover has a vent, and the upper cover can open or close the vent, ensuring that the food processor cannot be started when the user closes the vent. However, this technical solution has the following drawbacks: when drinking beverages from the cup, the heavy base makes drinking inconvenient, and the cup body is usually deep, making it difficult to clean the cup body and the pulverizing blade located at the bottom. Furthermore, in this solution, the cup lid directly senses the sensing element on the side wall of the cup body. Due to spatial constraints, the sensing element of the cup body is usually set as a reed switch or Hall element, while the sensing element of the cup lid is a magnet. The reed switches and Hall effect sensors mentioned above cannot be directly disconnected from the mains power, so there is still a risk that the food processor will start when the lid is removed due to the failure of the detection element; the magnetic sensing element is also easily affected by the external magnetic field, which may cause the food processor to misjudge and start abnormally.

[0005] The applicant's earlier patent application, CN202010269120.7, discloses a food processing machine. Compared to the previous solution, it features a detachable cup body and a base. The cup body has an upper opening and a lower opening. To prevent the cup body from being disassembled during normal operation, a locking structure is provided. After the cup lid is closed, the locking structure can interlock the cup body and the base. However, this solution only ensures the reliable installation between the cup body and the base. It does not provide specific implementation methods or corresponding technical guidance regarding the stable and reliable operation of the food processing machine, such as how to ensure that the food processing machine can only operate normally when maintaining internal and external communication.

[0006] The applicant's prior patent application CN201921365682.0 discloses a food processor, including a cup lid, a detachable cooking cup, and a base. To ensure the safety of the food processor, a connecting rod is provided inside the cooking cup, and a micro switch is provided inside the base. The cup lid includes an upper cover and a lower cover. When the user operates the upper cover to rotate, the vent is opened, allowing the cooking cup to communicate with the outside world. This also drives the push rod of the push rod mechanism to move downward, which in turn moves the switch connecting rod and triggers the micro switch. At the same time, the cooking cup is radially positioned between itself and the base via the connecting rod, preventing the cup lid or cooking cup from accidentally falling off during processing and preventing the user from accidentally removing the cup lid or cooking cup during the food processor process. However, during product development, the applicant discovered the following shortcomings in the solution: While the switch linkage can lock the blending cup and base simultaneously when the top cover is rotated to open the vent, when the user rotates the top cover to close the vent for external transport, the switch linkage releases the lock between the blending cup and base. This still poses a risk of accidental removal of the blending cup. Although this prevents accidental activation of the food processor, the food inside the blending cup may spill out, affecting usability. In extreme cases, the threads of the food processor's lid and blending cup may be too tight, while the threads of the blending cup and base may be relatively loose. When removing the lid, if the user directly grasps the base to remove the blending cup, there is a risk that the blending cup may detach from the base while the lid remains attached.

[0007] As a leader in the food processing machine industry, the applicant continuously prioritizes the safety of its food processing machine products. For example, the applicant's CN202110324923.2 and CN202110324921.3 disclose different solutions to address the technical problem of accidental activation of food processing machines during use. These solutions include employing a first and second linkage to achieve interlocking of the lid locking and normal start-up of the food processing machine; and setting a locking linkage device to lock the cup body during normal operation of the food processing machine.

[0008] In its technical research, the applicant discovered that previous technical solutions mainly addressed the safety and stability of the food processor during operation, without considering the need to prevent accidental activation of the portable food processor when it is not in operation, such as when the user is carrying it. Alternatively, complex linkage structures were used to separately trigger the switch and lock the cup. However, such solutions are not suitable for portable food processors that require minimal size. Therefore, how to meet the safety requirements of the portable food processor in multiple usage scenarios—operation, carrying, and drinking—without increasing its size has become a pressing technical problem that this application's portable food processor needs to solve. Utility Model Content

[0009] The purpose of this utility model is to provide a safe and reliable food processing machine. While ensuring that the cup of the food processing machine is detachable, has the function of opening for ventilation and sealing for portability, it further solves the technical problem that the locking structure of the existing food processing machine is complicated and cannot fully guarantee that the cup and the base cannot be disassembled when carried.

[0010] To solve the above-mentioned technical problems, this utility model provides a safe and reliable food processing machine, comprising: a cup body having an upper opening and a lower opening; a base connected to the lower opening of the cup body, a motor being installed inside the base, and a pulverizing component extending into the cup body and driven by the motor being installed on the top of the base; and a cup lid covering the upper opening of the cup body; wherein the base is equipped with a micro switch electrically connected to the motor; the cup lid having: a cup lid body; an exhaust port disposed on the cup lid body to connect the interior and exterior of the cup body; and a linkage exhaust device having a transparent opening for opening the exhaust port. The cup body has a gas position and a closed position for sealing the exhaust port; the side wall of the cup body is provided with a trigger link extending vertically, the trigger link having: a first position: the position of the trigger link when the cup lid is not installed; a second position: the cup lid is installed and the linkage exhaust device is not in the venting position, the cup lid pushes the trigger link to move downward from the first position, so that the trigger link part extends into the base to achieve interlocking between the cup body and the base; a third position: the linkage exhaust device in the venting position pushes the trigger link to move downward from the second position to trigger the micro switch.

[0011] Preferably, the top of the cup body is provided with a trigger groove, the top end of the trigger rod is located in the trigger groove, the cup lid is provided with a trigger part that extends into the trigger groove and abuts against the trigger rod, and the linkage exhaust device pushes the trigger part to displace the trigger rod to the trigger position.

[0012] Preferably, the triggering part includes a trigger plate disposed on the cup lid body, the bottom end of the trigger plate abutting against the trigger linkage, and the linkage exhaust device pushing the trigger plate to move downward.

[0013] Preferably, the trigger linkage has a second push position that cooperates with the cup lid body and a third push position that cooperates with the linkage exhaust device.

[0014] Preferably, the linkage exhaust device includes a flip cover hinged to the cup lid body. The cup lid body has a first fastening position and a second fastening position that engage with the flip cover. The flip cover is fastened to the first fastening position to close the exhaust port. The flip cover is fastened to the second fastening position to push the trigger linkage to the trigger position.

[0015] Preferably, the linkage exhaust device further includes a latching cover hinged to the free end of the flip cover, the first latching position and the second latching position are disposed on the outer side walls of opposite sides of the cup lid body, and the latching cover is folded down to latch with the first latching position and the second latching position respectively.

[0016] Preferably, the linkage exhaust device includes a rotating cover rotatably connected to the cup lid body. The rotating cover has a second exhaust port that extends through the axial direction. When in the first connection position, the second exhaust port is misaligned with the exhaust port. When in the second connection position, the second exhaust port coincides with the exhaust port.

[0017] Preferably, the side wall of the cup body is provided with a mounting groove for mounting the trigger link and a cover for covering the mounting groove, and the trigger link is disposed in the mounting groove and moves along the axial direction of the cup body.

[0018] Preferably, the top of the base is provided with a locking hole into which the trigger linkage extends.

[0019] Preferably, the base is further provided with a top rod that abuts against the trigger linkage and triggers the micro switch.

[0020] After adopting the above technical solution, this utility model has the following technical advantages.

[0021] 1. By analyzing the usage scenarios of the portable food processor and the fixed connection relationship between the cup body, base, and lid, the applicant disassembled the operating steps in each usage scenario, which are as follows: The user assembles the cup body on the base and holds the food or drinks the processed beverage: At this time, the food processor only consists of two parts, the cup body and the base. Unless the user has emptied the food in the cup body to store the food processor, the user usually does not directly disassemble the cup body and the base. At this time, the top of the cup body is open, and the user can directly see the situation inside the cup body. There is usually no risk of food spillage caused by the user disassembling the cup body and the base. The user closes the lid on the cup body to realize the next processing step or to carry it out. This further includes the normal working state of the food processor and the state of stopping processing and carrying it.

[0022] During normal processing, regardless of whether the food processor has a heating function, the crushing parts will collide with the food and generate heat during operation, thereby increasing the pressure inside the cup. When the food processor has a heating function, the internal pressure will increase rapidly during heating. Therefore, the food processor must be equipped with a pressure relief structure to adjust the internal pressure. For portable food processors, a high-pressure processing environment is not required, so a vent that directly connects to the inside and outside is sufficient. However, when carrying the food processor, the cup lid may not be facing upwards, so the vent needs to be sealed when carrying it.

[0023] An analysis of existing technical solutions reveals that they all break down each usage state individually and solve the corresponding technical problems, which cannot meet the safety requirements of all usage states. Existing technical solutions also cannot be simply superimposed to meet the needs of multiple usage scenarios. Even food processing machines in more conventional fixed kitchen scenarios usually require multiple interconnected linkage devices to achieve safety, locking and other requirements, which cannot meet the needs of portable products that are simple, small in size and have higher safety requirements.

[0024] In this application, the detachable connection between the food processor cup and the base is first ensured. Based on this, the application first installs a linkage exhaust device on the cup lid, using this device to open or close the exhaust port of the cup lid, meeting the needs of the food processor for venting during operation and sealing during transport. Furthermore, a microswitch electrically connected to the motor is installed inside the base, and a trigger linkage is installed on the side wall of the cup body, with the trigger linkage having a first position, a second position, and a third position. It should be noted that the linkage exhaust device typically has a certain stroke; for example, in a hinged configuration, it rotates between two positions. Typically, the exhaust port is only completely closed in the closed position, while leaving the closed position allows the exhaust port to communicate with the outside. The venting position here refers to a preset position where the linkage exhaust device can be fixed or triggered with other structural devices, not simply an intermediate position where the exhaust port is open only after leaving the closed position.

[0025] The trigger linkage, cup lid, and linked exhaust device form an interactive interconnection to meet the different control needs of the food processor in various processing states. When only the cup body is installed on the base, as mentioned earlier, the user can clearly understand the current status of the food processor and will not invert it. Therefore, there is no risk even if the cup body and base are not interlocked. At this time, the microswitch is not triggered, and the food processor will not start normally, ensuring basic safety. When the user installs the cup lid, the cup lid can push the trigger linkage to a second position to interlock the cup body and base, thus preventing the user from directly separating the cup body and base while operating the food processor. Regardless of the position of the linked exhaust device, the interlock between the cup body and base is guaranteed. That is, as long as the cup lid, cup body, and base are installed correctly, it prevents the cup body from being removed from the base without removing the cup lid.

[0026] Based on the above, when the user needs to start the food processor, they only need to fix the linkage exhaust device in the venting position with the exhaust port open. The linkage exhaust device can then further push the lever triggering link, pushing the triggering link from the second position down to the third position to trigger the micro switch, allowing the food processor to start normally. This links the disassembly of the cup body and the installation of the cup lid. Furthermore, it links the start-up of the food processor with whether the exhaust port is properly open, meeting the needs of various usage scenarios for the food processor, including normal installation, preventing accidental separation of the cup body and the base, ensuring sealing, and preventing start-up while sealed. Compared with existing technologies, this application's solution achieves different functions by setting a single triggering link in different positions, eliminating the need for multiple linkage structures as in existing solutions. This meets the requirements of a portable food processor that is compact, easy to operate, and safe and reliable.

[0027] 2. If the trigger rod is directly exposed or in a position easily accessible to the user, the user could potentially trigger the microswitch and start the food processor even without the cup lid installed, posing a risk. To further enhance the safety of the food processor, this design includes a trigger groove at the top of the cup body, with the tip of the trigger rod located within it. The depth of the trigger groove prevents the user from directly touching the trigger rod. The cup lid is designed to extend into the trigger groove and abut against the trigger rod. Furthermore, the linked venting device pushes the trigger rod to a third position when in the venting position, ensuring the food processor is even safer and more reliable.

[0028] 3. Preferably, the trigger groove can be set to a smaller size to avoid easy access by the user. Correspondingly, the cup lid is provided with a trigger plate, which is used to push the trigger link and the trigger plate is pushed downward by the linkage exhaust device to realize the normal operation of the food processing machine. The trigger groove can also limit the trigger plate to ensure that the trigger plate reliably abuts against the trigger link, thereby ensuring that the cup lid reliably pushes against the trigger link.

[0029] 4. Different linkage venting devices can be set for different cup lid structures. The cup lid body and the linkage venting device can be set to the same position for pushing the trigger link. Furthermore, the trigger link has a second pushing position for the cup lid body to push, and a third pushing position for the linkage venting device to push. When the cup lid is installed in place, the cup lid body pushes the second pushing position to push the trigger link to the second position; when the linkage venting device is in the venting position, it pushes the third pushing position to push the trigger link to the third position. Furthermore, the trigger link can be provided with different branches to abut against the cup lid body and the linkage venting device respectively, realizing the function of locking and triggering the micro switch by different abutments of a single trigger link.

[0030] 5. A flip cover is directly hinged to the cup lid body, and a first fastening position and a second fastening position are provided on the cup lid body. The user can clearly fasten the flip cover to the first fastening position or the second fastening position respectively to achieve the purpose of carrying and starting operation. The simultaneous provision of the first fastening position and the second fastening position can avoid the accidental triggering of the linkage exhaust device between two different functions, and avoid the unstable switching of the linkage exhaust device between the ventilated position and the closed position.

[0031] 6. Further, a snap-on cover is provided, and a first snap-on position and a second snap-on position are provided on the outer side walls on both sides of the cup lid body. The flip cover is horizontally attached to the upper part of the cup lid body, while the snap-on cover is vertically snapped to the side wall of the cup lid body, so that the snap-on cover and the flip cover are set vertically or nearly vertically, and the forces on both are distributed in the normal direction, so as to prevent the snap-on cover or the flip cover from being accidentally touched and detached from the snap-on state with the cup lid body, thereby ensuring the sealing state and stable and reliable working state of the food processing machine.

[0032] 7. A rotating cover is provided that rotates relative to the cup lid body, and the rotating cover has a second vent corresponding to the vent. When in the closed position, the second vent and the vent are misaligned; when in the vented position, the second vent and the vent are connected, so as to more easily and completely close or open the vent. The rotating cover, for example, can be a rotating cover with the same diameter as the cup lid body, so as to form an integral shape with the cup lid body, improving the visual effect of the food processing machine.

[0033] 8. A mounting groove is provided on the side wall of the cup body for mounting the trigger link. This ensures a compact overall spatial structure for the cup body. The trigger link is axially oriented, requiring only its axial length to be guaranteed. In the radial and circumferential directions, only reliable fit with the mounting groove and the strength of the trigger link itself are needed. The mounting groove is then sealed with a cover to prevent users from directly touching the trigger link. This also ensures a simpler and more elegant overall appearance for the food processor, improving user satisfaction. The trigger link, extending axially along the cup body, has sufficient axial movement space to facilitate switching between the first, second, and third positions, preventing interference when the distance between positions is too short. For example, if the distance between the second and third positions is too short, the trigger link in the second position may be accidentally pushed, triggering the microswitch.

[0034] 9. A locking hole is provided directly on the top of the base for the trigger rod to extend into. When the user installs the cup body, it is convenient for the trigger rod to extend from the bottom of the cup body and into the locking hole, ensuring a compact connection between the cup body, the base, etc., thereby reducing the overall size of the food processor. While ensuring the safety of the food processor, it further facilitates user operation and carrying.

[0035] 10. The base needs to house a motor, a micro switch, and may also include a heating element, a control board, a power board, and other components. The micro switch may not necessarily be mounted on the top of the base for direct triggering by the trigger rod. Furthermore, the top of the base must have a through hole for the trigger rod to extend into. To prevent water from directly entering the through hole and flowing towards the micro switch, a push rod is further provided within the base. One end of the push rod abuts against the trigger rod, and the other end abuts against the micro switch, transmitting the force of the trigger rod to the micro switch. In this way, the micro switch can be positioned within the available space of the base, and water seepage to the micro switch is prevented. Attached Figure Description

[0063] Portable food processors are gaining popularity due to their portability and ease of use on the go. However, their usage scenarios differ significantly from traditional food processors. Traditional blenders, like high-speed blenders, don't prioritize weight and simply require the cup to be mounted on the base to start operating. They utilize anti-overflow controls to process beverages like soy milk. Traditional blenders also have adequate venting channels in the lid during heating and even employ pressure blending. However, this approach is unsuitable for portable food processors. Without a venting structure, increasing pressure can cause the lid to pop open, splashing food and posing a risk to the user. A venting structure, on the other hand, allows leakage during transport, also affecting usability. Furthermore, while detachable cups and bases facilitate cleaning, this can lead to accidental spillage. When the applicant was accumulating preliminary technical solutions, it found that the original technical solutions still had shortcomings: the existing solutions were mostly focused on a certain technical problem of portable food processors, and did not connect and solve the technical problems of portable solutions based on the same structural solution. Furthermore, the locking structure of existing traditional blenders has the disadvantages of being complex and taking up a large space, and cannot be easily applied to portable products.

[0064] To overcome the shortcomings of existing solutions, the applicant, based on existing technology, further proposes a safe and reliable food processing machine, such as... Figures 1-19 As shown, the food processor includes a base 1, a cup body 2, and a lid 3. The cup body 2 has an upper opening and a lower opening to form a cylindrical shape. The base 1 is detachably connected to the lower opening of the cup body 2. A motor is installed inside the base 1, and a pulverizing component driven by the motor is located at the top. The pulverizing component extends into the cup body 2 to pulverize the food. The lid 3 covers the upper opening of the cup body 2 and seals it. The detachable cup body 2 and base 1 allow users to easily remove the cup body 2 for cleaning and to clean the pulverizing component on the top of the base 1. A closed bottom lid can also be added to the lower opening of the cup body 2, so that the cup body 2 is sealed by the bottom lid and the lid, respectively, forming a separate container. This eliminates the need to remove the base when drinking, making it more convenient for the user.

[0065] To address the issue that the food processor needs to vent during operation but needs to be sealed and inoperable when portable, this application incorporates a microswitch electrically connected to the motor within the base. The food processor cannot be started when the microswitch is not triggered. The cup lid includes a lid body and a linked venting device. The lid body has a vent that connects the inside and outside of the cup, allowing for timely release of pressure when the pressure inside the cup increases. The linked venting device is configured with a venting position for opening the vent and a closing position for closing the vent. The food processor can start normally when the vent is open, but cannot start when the vent is closed, ensuring safety and portability. It should be noted that the linkage exhaust device is usually set with two specific fixed positions to indicate the ventilation position and the closed position. However, when the linkage exhaust device leaves the closed position, the exhaust port is already connected to the outside to perform the function of ventilation. But at this time, the linkage exhaust device has not reached the ventilation position. The ventilation position in this application refers to the position that the food processing machine is specifically set with the linkage exhaust device having a definite position to fully open the exhaust port.

[0066] Building upon this, the present application further provides a vertically extending trigger link on the side wall of the cup body, wherein the upper and lower ends of the trigger link are respectively associated with the cup lid and the base. The trigger link has the following characteristics:

[0067] First position: This refers to the normal installation when the trigger link is located on the side wall of the cup body and does not abut against the cup lid or the base. This mainly refers to the position of the trigger link when the cup body is installed on the base but the cup lid is not installed. At this time, it is necessary to make it convenient for the user to install and remove the cup body without being affected by the trigger link.

[0068] Second position: After the user completes the pre-processing preparations, the cup lid is placed on the upper opening of the cup body. At this time, as long as the linkage exhaust device is not set in the venting position of the exhaust port, the cup lid will press the trigger linkage downward and move from the first position to the second position. At this time, the trigger linkage interlocks the cup body and the machine base, that is, the user cannot directly remove the cup body from the machine base while the cup lid is in place, so as to ensure that the cup body is reliably fixed on the machine base and ensure the safety of the food processing machine. At this time, the user can fix the cup lid in the closed position for easy carrying of the food processing machine.

[0069] Third position: When the user needs to start the food processor normally, the exhaust port needs to be opened simultaneously. The user opens the exhaust port by setting the linkage exhaust device to the vent position. At this time, the linkage exhaust device is associated with the trigger rod, which further pushes the trigger rod downward from the second position to the third position. At this time, the trigger rod triggers the micro switch, and the food processor is powered on and can start normally. This strongly links the opening of the exhaust port and normal start-up of the food processor, eliminating the risk of starting the machine before the exhaust port is opened. It should be noted that when the trigger rod moves from the first position to the third position, it must pass through the second position. That is, if the linkage exhaust device is already in the vent position when the user installs the lid, the trigger rod will be pushed by the lid and the linkage exhaust device together, moving from the first position, through the second position, and directly to the third position, enabling the food processor to start. However, at this time, the food processor meets the conditions for normal start-up, and there is no safety risk for the user to start the food processor.

[0070] In this application, the triggering linkage is arranged in three positions from top to bottom: a first position, a second position, and a third position. The displacement of the triggering linkage between these positions is linked to the venting device of the cup lid. This satisfies the processing needs of the portable food processor in this application, which has multiple different usage states. Users only need to assemble the cup body, base, and cup lid in different positions to meet the corresponding functional requirements. This application ensures that the cup body and base are locked when the cup lid is installed in place, preventing users from accidentally opening them directly. Furthermore, the triggering linkage is further pushed to trigger the microswitch, eliminating the need for multiple linkage structures. This fulfills the requirements of a compact, easy-to-operate, and safe portable food processor.

[0071] As a preferred implementation method, such as Figures 1-14 As shown, the food processing machine includes a base 1, a cup body 2, and a cup lid 3. Figures 1-3As shown, the cup lid 3 includes a cup lid body 31, a vent 34, and a linkage venting device. Preferably, the linkage venting device includes a flip cover 32 hinged to the cup lid body 31 and a latching cover 33 hinged to the free end of the flip cover 32. A hinge shaft 332 is provided between the latching cover 33 and the flip cover 32. The cup lid body 31 has a first latching position and a second latching position that engage with the flip cover 32. When the flip cover 32 is latched in the first latching position, it forms a closed position that closes the vent 34. When latched in the second latching position, it forms a venting position that opens the vent 34. In this embodiment, the top of the cup lid body 31 is provided with a latching groove 35, which extends across the top of the cup lid body 31. The first latching position and the second latching position are respectively formed on the two side walls of the cup lid body 31 corresponding to the latching groove 35. Preferably, the hinge axis of the flip cover 32 is located at the rotation center of the cup lid body 31. This allows the latch 33 to fold further downwards to latch onto the first and second latching positions located on the side wall when the flip cover 32 is in contact with the cup lid body 31. Simultaneously, since the first and second latching positions are located on opposite sides of the cup lid body 31, the user can more intuitively rotate the flip cover 32 to the corresponding latching position. A silicone plug 341 is also provided at the vent 34, with a venting channel 342, and the vent 34 is close to the hinge center of the flip cover 32. On one hand, this allows the flip cover to apply greater force when closing the vent 34, preventing normal internal pressure from pushing the flip cover 32 open; on the other hand, the vent near the center of the cup lid body makes it inconvenient for the user to drink directly from the vent, thus preventing burns when drinking directly from the vent without knowing the state of the beverage inside.

[0072] Preferably, the cup lid body 31 is further provided with an upper mounting hole 36, and a trigger piece 5 is provided at the upper mounting hole 36. Figures 1-7As shown, the trigger piece 5 has an abutment 51 protruding from the upper mounting hole 36 and an upper limit groove 52. An upper limit member 53 is provided at the upper limit groove 52. The upper limit member 53 is smaller than the width of the upper limit groove 52, so that the trigger piece 5 can move up and down within the cup lid body 31 under the restriction of the upper limit member 53. The upper mounting hole 36, the trigger piece 5, and the vent 34 are located on both sides of the hinge axis of the flip cover 32. The cup lid body 31 has a first fastening protrusion 371 at the first fastening position and a second fastening protrusion 372 at the second fastening position. The cover 33 has a fastening hole 331. When the flip cover 32 is rotated to the first fastening position, it abuts against the silicone plug 341 to block the vent passage 342. At the same time, the cover 33 is folded downward so that the fastening hole 331 engages with the first fastening protrusion 371, ensuring that the flip cover 32 is securely fastened. Correspondingly, when the flip cover 32 rotates to the second engaging position, it abuts against the abutment 51 and pushes the abutment 51 downward, causing the cover 33 to fold downward so that the engaging hole 331 engages with the second engaging protrusion 372. Here, the angles at which the cover folds downward are opposite in the first and second engaging positions.

[0073] Preferably, the cup body 2 includes a cup body 21, the side wall of which is provided with a mounting groove 22 and a cover 23. The trigger rod 4 is disposed in the mounting groove 22, and the cover 23 covers the trigger rod 4 and the mounting groove 22. To ensure the contact effect between the upper and lower ends of the trigger rod 4, the trigger rod 4 is provided with a rod body 41, with an upper extension section 43 at the upper end and a lower extension section 42 at the lower end. The middle area of ​​the rod body 41 is also provided with an elastic groove 45, and a first spring 44 is provided in the elastic groove 45. The first spring 44 can push the trigger rod 4, so that the trigger rod 4 is in a preset position of a first position. The first spring is configured to push the trigger rod to maintain the first position when it is not subjected to external pressure, so that when the cup body is installed on the base, the trigger rod will not be exposed and will not affect normal installation. It is understandable that an elastic wall structure can be provided between the trigger link and the cup body to push the trigger link; or, a magnetic element can be provided between the cup body and the trigger link, using the mutual repulsion of the magnetic elements to push the trigger link to remain in the first position. It is also understandable that the trigger link may not be provided with a first spring for pushing and resetting. In this case, when the cup body is not installed on the base, the bottom of the trigger link may be partially exposed. The bottom end of the trigger link can be set to be an inclined surface facing the screw-on side, and a vertical surface facing the unscrewed side. In this way, when the cup body is installed, the inclined surface is pushed upward by the base to ensure the normal installation of the cup body and the base. In the reverse direction, the base cannot push the vertical surface of the trigger link, and when the cup lid is installed in place, it can prevent the trigger link from moving upward, thereby ensuring the safe locking of the cup body and the base.

[0074] The cover 23 and the cup body 21 form a trigger groove 24 at the top of the mounting groove 22. When the trigger rod 4 is in the first position, the top of the upper extension 43 is located in the trigger groove 24. The cup lid 3 is provided with a trigger part that extends into the trigger groove 24 to push the trigger rod 4. In a preferred embodiment, the trigger part includes the trigger piece 5. When the cup lid 3 is rotated into place, the trigger piece 5 pushes the trigger rod 4 from the first position to the second position. When the flip cover 32 is fastened to the second fastening position, the flip cover 32 pushes the trigger piece 5 to push the trigger rod 4 from the second position to the third position. In this way, when the cup lid 3 is installed in place, the cup lid 3 can push the upper extension 43. However, since the upper extension 43 is not exposed, the user cannot directly trigger the upper extension 43, so as to avoid the user directly pushing the trigger rod and causing the food processor to be accidentally started, thus ensuring the safety of the food processor. As an alternative implementation, a trigger hole may also be provided on the top of the cup body, and the cup lid may be inserted into the trigger hole to push the trigger linkage.

[0075] Preferred, such as Figures 1-8 As shown, the base 1 includes a housing 11 and a blade disc 12, with the blade disc 12 positioned at the top opening of the housing 11. In this embodiment, the blade disc 12 is further equipped with a heating element for heating and cooking the food inside the cup 2. A motor (not shown) is fixed to the central area of ​​the bottom side of the blade disc 12, with the motor shaft extending into the cup 2 and a pulverizing element positioned at the top of the motor shaft. The housing 11 contains a push rod 13, a micro switch 14, and a second spring 15, and a locking hole 16 is provided at the top of the housing 11. In a preferred embodiment, the push rod 13 includes an integrally formed first push rod post 131 and a second push rod post 132 arranged in parallel. The top end of the first push rod post 131 corresponds to the locking hole 16, the lower end of the second push rod post 132 abuts against the micro switch 14, and the second spring 15 is sleeved on the second push rod post 132 and pushes the push rod 13 to disengage from the micro switch 14 in normal operation. The push rod 13 is configured with a first push rod post and a second push rod post. On one hand, this allows the push rod to trigger a micro switch located away from the locking hole, facilitating the installation of the micro switch within the base. On the other hand, it also allows the micro switch to be offset from the locking hole, preventing water from seeping into the base through the locking hole and directly reaching the micro switch, thus ensuring greater safety. It is understood that the push rod may also have only a single push rod post, abutting against the micro switch at its bottom; alternatively, the base may not have a push rod, and the micro switch may be directly positioned at the locking hole, allowing it to be triggered directly in a third position when the triggering rod extends into the locking hole. Furthermore, the base may also have a sealing structure at the locking hole to prevent external water from seeping into the base.

[0076] The specific operation process of the preferred embodiment of the safe and feasible food processing machine described in this application is as follows: Figures 6-14 As shown, wherein, Figures 6-8 When the cup lid, cup body and base of the food processing machine are assembled, and the linkage exhaust device, i.e. the flip cover, is between the first and second fastening positions and the triggering rod is not pushed, the mutual cooperation relationship between the cup lid, cup body and base is as follows: at this time, the triggering rod is in the second position under the push of the cup lid. Figures 9-11 When the cup lid, cup body and base of the food processing machine are assembled and the flip cover is in the first snap-fit ​​position, the mutual cooperation between the cup lid, cup body and base is such that the trigger linkage is in the second position under the push of the cup lid. Figures 12-14When the cup lid, cup body, and base of the food processing machine are assembled and the flip cover is in the second engaged position, the mutual cooperation between the cup lid, cup body, and base is as follows: At this time, the trigger linkage is in the third position under the push of the cup lid and the flip cover. The following is a detailed description of the various positions of the trigger linkage.

[0077] The trigger linkage is in the first position: as follows: Figure 1 As shown, when the cup body 2 is in a free state, or when only the cup body and the base are fixedly connected, the trigger rod 4 is only pushed by the internal first spring 44 to engage with the top end of the mounting groove 22. Preferably, in this state, the lower extension 42 at the bottom of the trigger rod 4 retracts into the mounting groove 22, and the upper extension 43 at the top is located in the trigger groove 24. This prevents the user from touching the trigger rod at the top and also prevents the trigger rod from affecting the normal assembly of the cup body when assembling the cup body and the base. It should be noted that the cup body and the base are usually fixed by screw connection, such as by threads or screw-on buckles, and the cup body is rotated into place when the trigger rod and the locking hole are aligned. Therefore, the trigger rod will not extend into the locking hole during assembly in the first position, so that the cup body can be installed and removed normally. It is understandable that the cup body and the base can also be connected by a press-fit method, or by a separate external cover. In this way, the cup body and the base do not need to rotate relative to each other, and the trigger rod can be directly inserted into the locking hole to achieve the alignment effect.

[0078] The trigger lever is in the second position. When the cup lid 3 is installed in place with the cup body 2, and the flip cover 32 is not in the second engaged position, the cup lid 3 pushes the trigger lever to the second position. Here, the flip cover 32 can be in a closed position, fixedly engaged with the cup lid 3 to close the vent, or it can be between a vented position and a closed position, for example, when the user operates the flip cover 32.

[0079] like Figures 6-8 The diagram illustrates the positional relationship of the functional components of the food processing machine when the flip-top cover 32 is in the first and second engaging positions. Figure 6 As shown, the cup lid body 31 has a vent 34 near its center, and a silicone plug 341 is provided at the vent 34. The silicone plug 341 has a vent channel 342. The silicone plug 341 provides a better seal. The cup lid body 31 and its inner wall are threaded to mate with the cup body 21, and the outer wall of the cup lid body 31 has a first engaging protrusion 371. Figure 7As shown, the cup lid body 31 has a second fastening protrusion 372 on its other outer side wall opposite to the first fastening protrusion 371. The trigger piece 5 is disposed in the upper mounting hole 36, and the bottom end of the trigger piece 5 abuts against the upper extension section 43. Thus, the cup lid 3 pushes the trigger connecting rod 4 from the first position to the second position through the trigger piece 5. The trigger connecting rod 4 reacts to the trigger piece 5 under the action of the first spring 44, and under the limiting action of the upper limit member 53, the abutment 51 protrudes from the upper mounting hole 36. As mentioned above, the bottom end of the trigger piece 5 extends into the trigger groove 24 to push the upper extension section 43, without the upper extension section 43 being exposed outside the mounting groove 22, thus preventing the user from directly touching the trigger connecting rod 4. Meanwhile, since the top surface of the cup lid body 31 is provided with a fastening groove 35, and the abutment 51 protruding from the upper mounting hole 36 is located within the fastening groove 35, it can also prevent the user from directly triggering the abutment 51, thereby ensuring the safe use of the food processing machine. Figure 8 As shown, under the pushing action of the cup lid 3, the trigger link 4 moves from the first position to the second position. At this time, the lower extension 42 extends into the locking hole 16, locking the cup body 2 and the base 1 to prevent the user from directly removing the cup body 2. The lower extension 42 abuts against the top rod 13 and pushes the top rod 13 downward, but the displacement of the top rod 13 is insufficient to trigger the micro switch 14. Of course, it is also possible to set the lower extension 42 in the second position to not abut against the top rod 13, but only the lower extension 42 is inserted into the locking hole 16 and locked together. It is understood that the base can also be provided with a locking countertop at the top, or a locking notch at the top of the side wall of the base, and the trigger link extends into the locking countertop or locking notch to lock the cup body and the base.

[0080] like Figures 9-11 The diagram shows the positional relationship of the functional components of the food processing machine when the flip-top cover 32 is in the first engaged position. Figure 9As shown, the flip cover 32 rotates and fits into the fastening groove 35. The flip cover 32 presses against the silicone plug 341 to seal the vent channel 342. The fastening cover 33 further rotates downwards via the hinge shaft 332, causing the fastening hole 331 to engage with the first fastening protrusion 371, thus fastening the flip cover 32 to the first fastening position. Since the fastening cover 33 is fastened to the side wall of the cup lid body and the rotation of the flip cover is perpendicular to the normal, the fastening state of the flip cover can be better guaranteed, preventing the flip cover from disengaging. In this state, the vent is closed, and the beverage in the cup will not leak out of the vent, making it convenient for users to carry the food processor when going out. However, since the flip cover is not in the second fastening position, the trigger linkage is not pushed by the flip cover. Therefore, the trigger linkage remains in the second position, and... Figures 6-8 They are in the same position. Specifically, Figure 10 The positional relationship between the trigger linkage 4 and the trigger piece 5 described herein is maintained at... Figure 7 The state; Figure 11 The positional relationship between the trigger linkage 4, the push rod 13, and the micro switch 14 is maintained at the specified position. Figure 8 The state.

[0081] The trigger linkage in the second state can lock the cup body and the base, and does not trigger the microswitch. This prevents the user from directly separating the cup body and the base when there is a beverage in the cup, ensuring the safety of the food processor. Although the food processor can start normally as long as the vent is in a venting state, it is usually complex and costly to detect the real-time position of the flip cover. Therefore, this application only sets the food processor to an open venting state and enables the food processor to start normally when the flip cover is reliably fastened in the second fastening position. Regardless of whether the flip cover is in the closed venting state in the first fastening position, or in a position between the first and second fastening positions that allows the vent to vent, it is assumed that the flip cover is in a closed venting state. This ensures a safer and more reliable food processor while simplifying the structure and reducing costs.

[0082] The trigger linkage is in the third position. For example... Figures 12-14As shown, when the flip cover 32 is fastened to the second fastening position, the flip cover 32 pushes the trigger piece 5 and further pushes the trigger linkage 4 downward to the third position, and finally triggers the micro switch. Preferably, the trigger linkage 4 is also provided with a lower limit groove 46, and the side wall of the cup body 2 is provided with a fixing post 221. When the cover 23 is closed on the mounting groove 22, the fixing post 221 is inserted into the lower limit groove 46. The axial length of the lower limit groove 46 is greater than the outer diameter of the fixing post 221, so that when the trigger linkage 4 switches between the first position, the second position and the third position, the fixing post 221 moves within the lower limit groove 46. Specifically, as shown... Figure 12 As shown, when the flip-top cover 32 disengages from the first locking position, the vent 34 is opened, and the cup lid 3 returns to its original position. Figure 6 The normal exhaust state is shown. The pressurized gas inside the cup 2 can be normally discharged from the exhaust port 34, and the food processor can start normally without any risk. Figure 13 As shown, the flip cover 32 is fastened in the fastening groove 35, and the fastening cover 33 is fastened in the opposite direction to the other side of the cup lid body 31 via the hinge shaft 332, so that the fastening hole 331 is fastened with the second fastening protrusion 372. At this time, the flip cover 32 presses against the trigger piece 5, pushing the trigger piece 5 to move downward, and the trigger piece 5 further pushes the upper extension section 43, thereby driving the trigger connecting rod 4 to move downward to the third position. Figure 14 As shown, the trigger rod 4, reaching the third position, extends further into the locking hole 16, causing the lower extension section 42 to press the top rod 13 downwards. This causes the top rod 13 to reach the trigger position of the micro switch 14, triggering it and energizing the food processor. The food processor can then start and operate normally under user operation. At this time, the cup body remains locked, preventing the user from directly separating it from the base. The vent on the cup lid is open, allowing the internal gas to escape smoothly even if the food inside the cup expands due to heat. The food processor operates normally without any risk.

[0083] The food processor described in this application features a detachable lid, cup body, and base. Users can easily disassemble the cup body and base for convenient cleaning of all components, eliminating hard-to-reach areas and ensuring the food processor meets hygiene requirements. Furthermore, the detachable cup body can be fitted with a bottom cover, allowing the lid and base to be combined to form a portable drinking cup, eliminating the need to operate it with the base. Based on this, the present application provides a micro switch inside the base and a triggering link inside the cup body that can trigger the micro switch. Furthermore, the triggering link has a first position under normal conditions, a second position locking the cup body and the base, and a third position capable of triggering the micro switch to start the food processor. In this process, the cup lid pushes the triggering link from the first position to the second position, and then the linkage exhaust device pushes the triggering link from the second position to the third position. This achieves the linkage between a single triggering link structure and the cup lid and linkage exhaust device, resulting in a simple and efficient structure. It also ensures that the food processor is always in a safe operating state, thereby improving the safety of the food processor.

[0084] As an optional implementation method, such as Figures 15-18 As shown, the linkage exhaust device includes a rotating cover 62 rotatably connected to the cup lid body 61. The cup lid body 61 is provided with an exhaust port 631, and the rotating cover 62 is provided with a second exhaust port 632 that extends axially through it. When in the closed position, the second exhaust port 632 is misaligned with the exhaust port 631; when in the ventilated position, the second exhaust port 632 is connected to the exhaust port 631.

[0085] Specifically, the cup lid includes a cup lid body 61, a rotating cover 62, and a sealing gasket 64. The rotating cover 62 can rotate relative to the cup lid body 61 around the center of the cup lid body 61. A trigger push section 621 is provided on the edge of the rotating cover 62. The sealing gasket 64 is sandwiched between the cup lid body 61 and the rotating cover 62. The cup lid body 61 is provided with a vent 631, the rotating cover 62 is provided with a second vent 632, and the sealing gasket 64 is provided with a sealing vent 641. Preferably, the sealing gasket 64 is fixed to the cup lid body 61, and the sealing vent 641 coincides with the vent 631.

[0086] Figure 15 , Figure 16This describes the coordinated state of the various functional components of the food processor when the rotating cover 62 is in the closed position. When the rotating cover 62 is in the closed position, the second exhaust port 632 is misaligned with the sealing exhaust port 641 and the exhaust port 631. The sealing gasket 64 is completely fitted against the bottom side of the rotating cover 62 to seal the exhaust port 631. At this time, the cup lid body 61 pushes the trigger linkage to the second position. The rotating cover 62 is misaligned with the trigger linkage and does not push the trigger linkage. Therefore, the microswitch is not triggered, and the food processor cannot be started normally. However, the exhaust port is in a closed state, fulfilling the need for carrying the food processor when going out.

[0087] Figure 17 , Figure 18 This describes the coordinated state of the various functional components of the food processor when the rotating cover 62 is in the ventilated position. When the rotating cover 62 is in the ventilated position, the second exhaust port 632 coincides with the sealed exhaust port 641 and the exhaust port 631, allowing airflow between the inside and outside of the cup body through the exhaust port 631, the sealed exhaust port 641, and the second exhaust port 632. At this time, the cup cover body 61 first pushes the trigger linkage to the second position where the cup body and base are locked. When the rotating cover 62 is rotated to the ventilated position, the trigger pushing section 621 inserts into the trigger groove on the side wall of the cup body, further pushing the trigger linkage downwards from the second position to the third position, thereby triggering the micro switch and enabling the food processor to start normally. At this time, the exhaust port is also normally open, thus meeting the conditions for normal start-up.

[0088] Similar to the aforementioned implementation, in the scheme where the linkage exhaust device is configured as a rotating cover, during the rotation of the rotating cover from the closed position to the ventilated position, the overlapping area between the second exhaust port and the exhaust port continuously increases. However, as long as the second exhaust port and the exhaust port are connected, internal and external exhaust can be achieved. However, to ensure that the exhaust speed meets the requirements, when set in the ventilated position, the second exhaust port and the exhaust port are usually completely overlapping, that is, the overlapping area between the second exhaust port and the exhaust port is a preset maximum.

[0089] The rotation center of the linked venting device coincides with the center of the cup lid body, making the rotating lid essentially rotate around its own center. This reduces the space occupied by the rotating lid during rotation and makes it easier for the user to switch between the venting and closed positions. Simultaneously, the food processor allows the trigger lever to sequentially switch between the first, second, and third positions, and the trigger lever can only be pushed to the third position to trigger the microswitch when the rotating lid is in the venting position, thus activating the food processor and ensuring its safety and reliability. By using the cup lid body and the rotating lid to push the trigger lever, no additional components are needed, resulting in a simple, reliable structure that meets the requirements of a portable, lightweight, and compact food processor.

[0090] As an optional implementation method, such as Figure 19 As shown, the linkage venting device includes a rotating cover 72 on which the cup lid body 71 is mounted. The triggering rod 4 has a second pushing position and a third pushing position. The cup lid body pushes the second pushing position, causing the triggering rod to reach a second position. The rotating cover pushes the third pushing position, causing the triggering rod to reach a third position. The cup lid body also has an vent 73. When in the venting position, the rotating cover 72 opens the vent 73.

[0091] Specifically, such as Figure 19 As shown, the side wall of the cup body 2 is provided with a triggering link 4, and the top of the triggering link 4 is provided with a staggered step, which forms a second pushing platform 471 and a third pushing platform 472. The cup lid includes a cup lid body 71 and a linkage exhaust device. The linkage exhaust device includes a rotating cover 72 that is rotatably disposed relative to the cup lid body 71. Preferably, the rotation center of the rotating cover 72 coincides with the axis of the cup lid body 71. The cup lid body is provided with an exhaust port 73. The cup lid body 71 is provided with a body pushing section 711, and the rotating cover 72 is provided with a rotating cover triggering section 721.

[0092] When the cup lid is installed on the cup body 2, the main body pushing section 711 pushes the second pushing platform 471, causing the trigger linkage 4 to reach the second position where the cup body and the base are locked. When the rotating cover 72 is rotated to the venting position, the rotating cover 72 makes the exhaust port 73 open to the outside, and at the same time, the rotating cover trigger section 721 presses the third pushing platform 472, forcing the trigger linkage 4 to move downward from the second position to the third position, triggering the micro switch to meet the start-up conditions of the food processing machine.

[0093] The trigger linkage is equipped with a second push platform and a third push platform, which can respectively abut against the cup lid body and the linkage exhaust device. This can better prevent the trigger linkage from being accidentally triggered by the cup lid, and only push the trigger linkage to the preset position when the cup lid is set in the corresponding position, ensuring that the food processing machine is safer and more reliable.

[0094] As an optional implementation, the linkage venting device includes an auxiliary cover disposed on the cup lid body, the auxiliary cover moving vertically relative to the cup lid body. Preferably, the auxiliary cover is pressed downward to a closed position that seals the vent; the auxiliary cover is lifted upward to a ventilated position that opens the vent, and at this time the auxiliary cover pushes the trigger linkage to move the trigger linkage to a third position.

[0095] Compared to existing technologies, the food processor described in this application not only features separate safety structures—for example, in one existing solution the cup body and base are mutually locked; in another, the cup lid has an exhaust position and a venting position—but also incorporates multiple states of linkage between the cup lid, cup body, and base. This allows the cup body and base to lock when the cup lid is in place, and the cup lid only triggers the microswitch and starts the food processor when the exhaust port is opened by the linkage exhaust device. This improves the safety of the food processor and meets the needs of various usage scenarios for portable food processors. Compared to traditional food processors, this application's trigger linkage has a first position, a second position, and a third position, each performing different functions and being able to link with the cup lid in different positions. This avoids the need for additional locking or triggering structures, making the food processor simpler and more efficient. While ensuring safety and reliability, the food processor is simple in structure, compact in size, and easy to carry.

[0096] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the present utility model are covered by the scope of the claims of the present utility model, and will not be listed here.
