Description

Technical Field

[0001] The utility model relates to the field of food processing, in particular to a food processing machine which has a machine base and a cup body and adopts magnetic non-contact transmission processing. Background Art

[0002] Existing blenders or food processors typically include a base and a detachable cup assembly mounted on the base. The base is equipped with a motor, and the cup assembly includes a cup for holding processed ingredients and a crushing element for crushing the ingredients. The motor rotates to drive the crushing element to rotate, thereby cutting and crushing the ingredients in the cup. Blenders rely on the crushing element to rotate at high speeds to crush the ingredients. Therefore, during operation, both the motor and the crushing element need to be in a high-speed rotating state. On the one hand, the motor itself and the lower coupling driven by the motor will generate vibration and noise when transmitting to the upper coupling. On the other hand, the impact generated by the high-speed collision between the crushing element and the ingredients will also be transmitted back through the upper coupling to the lower coupling, reacting to the motor, causing the blender to vibrate and make more noise during operation, resulting in a poor user experience. Therefore, how to reduce the reaction force of the crushing element on the motor, or even cut off the mechanical transmission between the two, becomes the primary issue in solving vibration and noise problems.

[0003] To address the technical issues of vibration and noise, the applicant has proposed a non-contact transmission solution. For example, Chinese utility model patent CN201020015043.4 discloses a non-contact transmission soybean milk maker, in which a magnetic non-contact upper and lower couplings are provided between the motor and the crushing cutter. These include both upper-lower transmission and inner-outer transmission. Because the couplings are not in direct contact, noise and vibration are significantly reduced during operation. However, in this solution, the upper and lower couplings remain fixedly connected to the machine head and cup lid, failing to reduce the connection structure between the machine head and cup lid for mounting the upper and lower couplings. Furthermore, the upper and lower couplings cannot be disassembled, resulting in various inconveniences in use.

[0004] Based on this, the applicant has further proposed an improved non-contact transmission solution. For example, Chinese invention patent CN201120194553.7 discloses an indirect transmission food processor, comprising a driving coupling mounted on the motor power output shaft and a driven coupling connected to a pulverizing tool. The driven coupling is provided with a certain floating space in the axial direction, allowing the pulverizing tool to slide appropriately in the axial direction to disengage stuck materials and enable normal operation of the pulverizing tool. This solution enables the cup body to be configured as a completely closed bottom structure without mechanical connection holes, thereby better solving the problem of liquid leakage in the mixing cup. Furthermore, in this solution, the driven coupling connected to the pulverizing tool can be removed from the container, facilitating cleaning of the pulverizing tool and driven coupling. Different pulverizing functions can also be achieved by replacing different pulverizing tools and driven couplings. However, a detachable crushing tool and driven coupling assembly presents the following problem: when a user operates a cup or container, such as pouring out slurry from the cup or container, the crushing tool and driven coupling may fall off the cup or container, potentially posing a risk of injury to the user. This application proposes a different fixing structure that secures the crushing tool to the bottom of the container while also ensuring that the crushing tool is detachable.

[0005] In order to prevent the crushing tool from detaching from the cup body, the prior art also discloses a magnetic fixation solution. For example, Chinese utility model patent CN202321907134.2 discloses a cutter disc assembly, in which a positioning piece is provided at the center of the cutter disc body, and a magnetic-driven cutter assembly is sleeved on the positioning piece. A magnetic attraction piece and an attracted piece that are magnetically attracted to each other are provided between the magnetic-driven cutter assembly and the positioning piece, so as to solve the problem of the magnetic-driven cutter assembly flying out and falling out of the mixing cup and injuring people.

[0006] However, such a solution still has technical defects for users: whether it is a mechanical fixing structure or a magnetic fixing structure, the purpose of its setting is to strengthen the installation strength between the tool and the cup body to prevent the tool from falling off the cup body during normal operation. For the solution using a mechanical fixing structure, the friction of the mechanical fixing structure can be increased, or mutually cooperating buckles can be set between the tool and the cup body, but such a solution requires the user to release the fixing structure first when operating the tool, which makes the operation cumbersome, and the complex fixing structure also brings inconvenience to cleaning. Similarly, the use of a magnetic solution requires a sufficiently large magnetic force between the magnetic part and the attracted part to prevent the tool from falling off the positioning part, but the user also needs to overcome the magnetic force to remove the tool during operation, which also brings inconvenience to the operation. And the plug-in positioning part and the magnetic part will also bring inconvenience to cleaning. Summary of the Invention

[0007] The purpose of this application is to provide a food processor that is easy to operate, so as to solve the technical problem in the prior art that when the magnetically driven crushing device is detachably arranged in the cup body, it can ensure sufficient safety protection in the cup body, and at the same time, it can facilitate the user to disassemble the crushing device without generating reaction force when the user operates it. As a result, there is an installation contradiction between requiring large interaction force and small interaction force, and the user's safety and convenient operation cannot be satisfied at the same time.

[0017] Preferably, the side wall of the cup body assembly is provided with an operating hole for the operating member to extend into, and a handle is further provided on the outside of the operating member.

[0018] Compared with the existing technology, this application has at least the following technical effects:

[0019] 1. This application continues the applicant's technical direction in contactless transmission, employing a mutually magnetically attracted active and passive magnetic disk assembly to achieve power transmission between the motor and the pulverizer, fundamentally preventing the pulverizer from transmitting vibration and noise to the motor during operation. The pulverizer is detachably mounted on the bottom of the cup, allowing it to fully adhere to the cup bottom and thus be close to the active magnetic disk assembly of the machine base, thereby reducing the distance between the active and passive magnetic disk assemblies and enhancing the magnetic attraction between the two. Furthermore, the cup assembly further includes a locking device on the outside of the cup body that is magnetically attracted to the pulverizer. The locking device is magnetically attracted to an internal magnetic member within the pulverizer to prevent the pulverizer from falling out of the cup body when not in use. Furthermore, to ensure that the pulverizer is securely locked within the cup assembly and does not risk flying out or falling out during user operation, the internal and external magnetic members of this application have sufficient magnetic attraction.

[0020] The applicant further analyzed and found that for the user, the pulverizing device is taken during a specific period of time, and the pulverizing device remains in a locked state during other periods. Therefore, it is only necessary to release the locking effect of the external magnetic part on the internal magnetic part during the picking stage to achieve the goal of maintaining a sufficiently large mutual magnetic attraction without affecting the user's normal picking operation, satisfying the user's safety and convenience in use. Therefore, the present application scheme sets a locking structure in the cup body assembly, first using the locking structure to reliably lock the pulverizing device in the cup body assembly, and further, the locking device also includes an operating member, which is set at the bottom of the cup body assembly and can be exposed to the outer wall of the cup body assembly. By operating the operating member, the external magnetic part can be pushed away from the internal magnetic part. In the normal locking state, the external magnetic part can be magnetically adsorbed with the internal magnetic part in the pulverizing device, and the magnetic attraction between the two is used to ensure that the pulverizing device can be stably and reliably installed in the cup body assembly. Whether during operation or when the user operates the cup body assembly, there is no risk of the pulverizing device flying out or falling off, ensuring the safety and reliability of the food processor. When the user needs to take the pulverizing device, the user operates the operating member to push the outer magnetic member away from the inner magnetic member, thereby increasing the distance between the magnetic poles of the outer and inner magnetic members. According to Coulomb's law, the magnetic attraction between two magnets is inversely proportional to the square of the distance between the two magnets. Therefore, when the distance between the outer and inner magnetic members increases, the magnetic attraction between the outer and inner magnetic members will also rapidly weaken, eventually reaching a state where the user can hardly perceive the magnetic attraction between the outer and inner magnetic members, thereby allowing the user to easily remove the pulverizing device from the cup assembly.

[0021] The operating member is used to push the external magnetic member. The operating member can be directly connected to the external magnetic member to directly push the external magnetic member. Of course, the operating member can also push the external magnetic member through an intermediate connecting member. For example, a connecting rod located in the cup body assembly is provided between the operating member and the external magnetic member. The operating member is pushed to drive the connecting rod to move, and the connecting rod then drives the external magnetic member to move. Even magnetic transmission is adopted between the operating member and the external magnetic member. For example, a closed cavity is provided at the bottom of the cup body assembly, and the external magnetic member is installed in the cavity. Magnets that magnetically cooperate with each other are provided between the operating member and the external magnetic member, and the operating member is pushed to drive the external magnetic member to move.

[0022] 2. The driven disk assembly and the inner magnetic component are enclosed in a shell to prevent them from leaking directly into the cup assembly. The driven disk assembly and the active disk assembly, as well as the inner magnetic component and the outer magnetic component, are all attracted to each other by non-contact magnetic attraction, and the shell does not affect the normal operation of the two modules. The inner magnetic component is arranged on the periphery of the driven disk assembly, and the inner magnetic component and the driven disk assembly are at the same height in the axial direction. In this way, when the crushing device is placed at the bottom of the cup, the inner magnetic component and the driven disk assembly can be closer to the bottom of the cup, and then can be magnetically attracted to the outer magnetic component and the active disk assembly located outside the bottom of the cup, respectively, to achieve the normal operation of the two modules. In particular, the magnetic attraction between the two mutually attracted magnetic components is inversely proportional to the square of the distance between the two magnets. Reducing the distance between the magnets can ensure a stronger magnetic attraction between the magnets. Correspondingly, the outer magnetic part is located outside the cup body and opposite to the inner magnetic part, which can ensure that the outer magnetic part and the inner magnetic part have a sufficiently close magnetic attraction distance, thereby ensuring that there is a sufficiently strong magnetic attraction force between the outer magnetic part and the inner magnetic part.

[0023] 3. A transmission cavity is provided at the bottom of the cup assembly, into which the active disk assembly extends. When the cup assembly is placed on the base, the active disk assembly can fit more closely to the bottom of the cup, thereby creating a closer distance between the active disk assembly and the driven disk assembly, ensuring a stronger magnetic attraction. The external magnetic member is disposed on the periphery of the active disk assembly. When the external magnetic member is positioned close to the cup bottom, it does not affect the normal installation of the active disk assembly. In this way, while fully ensuring the magnetic attraction between the active and driven disk assemblies, the magnetic attraction between the external and internal magnetic members can also be maintained.

[0024] 4. A guide groove and a guide column that cooperate with each other are provided between the cup body assembly and the external magnetic part, and the guide groove is used to limit the radial reciprocating movement of the external magnetic part along the cup body assembly, thereby switching between the locked position of the crushing device and the unlocked position of the crushing device. When the user needs to take the crushing device, the user operates the operating part to push the external magnetic part to move radially to unlock the crushing device. For the cup body assembly, there is installation space in both the axial and radial directions, and the diameter of the crushing device is much smaller than the diameter of the cup body assembly. Therefore, there is a large proportion of installation space between the crushing device and the outer wall of the cup body assembly. This space is used to accommodate the locking device and form a movement space to accommodate the locking device. There is no need to increase the installation space structure of the cup body assembly, the volume of the cup body assembly will not be increased, and the structure and shape of the existing product will not be affected.

[0025] 5. By forming a circumferentially extending guide groove between the cup body assembly and the external magnetic part, the external magnetic part can reciprocate circumferentially along the guide groove at the bottom of the cup body assembly to switch between a locked position and an unlocked position of the crushing device. Preferably, the bottom of the cup body assembly is preferentially provided for the cooperative transmission of the active disk assembly and the driven disk assembly. Therefore, the external magnetic part and the internal magnetic part are usually configured as a ring that is sleeved outside the active disk assembly and the driven disk assembly, wherein a plurality of groups of mutually attracted magnets can be provided between the external magnetic part and the internal magnetic part. When the external magnetic part is pushed by the operating part, the external magnetic part rotates and causes the magnets between the external magnetic part and the internal magnetic part to be misaligned, thereby achieving the unlocking of the internal magnetic part by the external magnetic part. The external magnetic part only rotates within the cup body assembly and does not occupy additional moving space, which can better facilitate the structural installation of the external magnetic part and ensure the stability and reliability of the external magnetic part.

[0026] 6. A pushing surface and a sliding surface that cooperate with each other are set between the operating member and the external magnetic member, wherein the pushing surface or the sliding surface has an angle with the moving direction of the operating member, so that when the operating member moves, it can utilize the cooperation of the pushing surface and the sliding surface to push the external magnetic member, so that the external magnetic member can reset in the required radial direction or circumferential direction.

[0027] 7. By forming a guide groove and a guide block that cooperate with each other in the axial direction between the cup body assembly and the external magnetic part, the external magnetic part can reciprocate along the axial direction of the cup body assembly to achieve the purpose of approaching or moving away from the internal magnetic part. It is only necessary to set an inclined surface with an axial tilt in the guide groove and the guide block, that is, the external magnetic part can be moved axially when the external magnetic part is pushed. For different cup body assemblies, as mentioned above, a space for the active disk assembly and the driven disk assembly to cooperate is usually set in the center of the cup body assembly, and other components of the cup body assembly need to be set on the periphery. For example, the heating element for heating the cup body assembly, the temperature sensor for monitoring the processing status of the cup body assembly, the temperature controller for providing safety protection, etc. are all set in the external space, which will also make the radial space available for the external magnetic part insufficient. In order to ensure that the active disk assembly can be close to the driven disk assembly, the cup assembly is usually provided with a space at the bottom for the active disk assembly to extend into. The outer magnetic part can use the above-mentioned space extending in the axial direction to increase the distance between the outer magnetic part and the inner magnetic part, thereby achieving magnetic separation between the outer magnetic part and the inner magnetic part. This arrangement fully utilizes the existing space of the cup assembly and does not require additional space and structural support. The structure is easy to implement and has strong reliability. Of course, when the magnetic attraction between the outer magnetic part and the inner magnetic part is too large, it is also necessary to add special moving space so that the increased distance between the outer magnetic part and the inner magnetic part is sufficient to weaken the magnetic attraction between the two.

[0028] 8. An upper cover and a lower cover that fit together are provided at the bottom of the cup body assembly. The installation space is formed inside the upper cover and the lower cover, and the external magnetic part is provided in the internal space, which can provide better protection for the external magnetic part. The upper cover is connected to the operating part, and can rotate and reciprocate in the circumferential direction under the pushing action of the operating part. At the same time, mutually matching inclined surfaces are provided between the upper cover and the external magnetic part. During the rotation of the upper cover, the external magnetic part can be driven to move back and forth in the axial direction, thereby widening the axial distance. The space formed by the combination of the upper cover and the lower cover first protects the external magnetic part to prevent the external magnetic part from being affected by external debris, etc.; in particular, it can also prevent the external magnetic part from being corroded by external liquids. Similarly, the external magnetic part only moves back and forth in the axial direction in the space formed by the upper cover and the lower cover. The space is more closed, which also ensures that the reciprocating motion of the external magnetic part is more reliable, thereby achieving stable and reliable locking or unlocking of the crushing device.

[0029] 9. The pulverizing device is unlocked by operating the operating member to move the outer magnetic member away from the inner magnetic member. When the user no longer needs to operate the pulverizing device, the outer magnetic member needs to be able to reset in time to lock the pulverizing device. In order to ensure that the outer magnetic member can reset in time, an elastic member is further provided to use the elastic member to push the outer magnetic member to return to the locked position in time. Of course, since the outer magnetic member and the inner magnetic member are in a magnetic attraction relationship with each other, and the active disk assembly and the driven disk assembly are in a magnetic attraction relationship with each other, when the pulverizing device is installed in place, the outer magnetic member is always under the action of magnetic attraction. Therefore, when the external force on the outer magnetic member disappears, the outer magnetic member can also be reset to the position locked to the pulverizing device under the action of the magnetic attraction of the inner magnetic member, or even under the action of the magnetic attraction of the driven disk assembly or the active disk assembly, without the need to add the elastic member.

[0030] 10. An operating hole is directly provided on the side wall of the cup body assembly so that the operating member can be exposed outside through the operating hole. The user can directly operate the operating member from the side wall and displace the external magnetic member. Even when the cup body assembly is placed on the machine base, the operating member will not affect the normal installation and placement of the cup body assembly, and the operation of the food processor will be more stable and reliable.

[0050] Food processors such as wall breakers, food processors, and soymilk makers usually rely on motors to drive the rotation of the crushing parts, which will collide and cut the ingredients placed in the cup body to complete the crushing of the ingredients. During the crushing process of current wall breakers, the rotation of the motor usually exceeds 10,000 rpm. During the collision and cutting process of the crushing parts with the ingredients, non-continuous and random impacts are formed between the ingredients and the crushing parts, and the crushing parts will generate vibration and noise. Such vibration will be transmitted back to the motor and the base, which will cause the motor and the base to generate more serious vibration and noise during operation. As a technological leader in food processing products in this field, the applicant is constantly exploring to find solutions to the problems of motor vibration and noise.

[0051] As previously mentioned, the applicants earlier proposed using a non-contact method to transmit power between the motor and the pulverizer, thereby severing the mechanical connection between the motor and the pulverizer and preventing the vibration and impact of the pulverizer from reacting to the motor. Due to the adoption of non-contact power transmission, the cup body does not need to be provided with a through hole for power transmission, facilitating the integrated design of the cup body. Furthermore, the pulverizer within the cup body is directly configured as a detachable structure. When the user requires pulverization, the pulverizer is installed, and when the user does not need pulverization, the pulverizer is not required. This facilitates the functional expansion of the food processor and avoids the need to clean the pulverizer after use.

[0052] However, the crushing device cannot be placed completely freely in the cup assembly. On the one hand, the crushing device needs to be magnetically transmitted with the active disk assembly, which requires that the crushing device and the active disk assembly can be aligned. On the other hand, if the crushing device is not limited, there is a risk that the crushing device will be pushed open when it is misaligned with the active ribs and will run around in the cup assembly. Furthermore, when the user operates the cup assembly, there is also a risk that the crushing device will fall directly from the cup assembly and injure the user. Therefore, in the prior art, a locking structure is still provided for the detachable crushing device to improve the reliability of the crushing device. There are usually two types of existing locking devices. One is a purely mechanical snap-in connection, which usually uses a card slot and a card block. The card slot has a locking position for the card block to prevent the crushing device from detaching. However, this structure is cumbersome and usually needs to be installed or unlocked in a specific position. It has higher requirements for users and there is also a risk of use caused by improper installation by the user. Another solution uses magnetic attraction, in which another magnetic attraction component is set between the crushing device and the cup body assembly to reliably adsorb the crushing device to the cup body assembly. This solution has low requirements for the locking and unlocking positions. The user can install or remove the crushing device at any position. When the user does not install it completely, the magnetic attraction can be used to reliably adsorb the crushing device into place, thereby improving the safety of the food processor.

[0053] However, the above-mentioned magnetic installation solution still has disadvantages. Since it is necessary to ensure that the pulverizing device and the cup body assembly are firmly fixed and that the cup body assembly can adsorb the pulverizing device into place, the magnetic attraction between the pulverizing device and the cup body assembly must be large enough. However, when the user needs to remove the pulverizing device, such a magnetic attraction will greatly hinder the user's operation. The greater the magnetic attraction, the more difficult it is for the user to remove the pulverizing device; but if the magnetic attraction is reduced, the safety locking function may fail. This creates a contradiction between the pulverizing device and the cup body assembly, which requires both a large interaction force and a small interaction force. The existing solution can only achieve the function of the food processor by sacrificing one of them or lowering the properties of both at the same time.

[0054] How to ensure that the magnetic attraction between the crushing device and the cup assembly is large enough to ensure absolute safety, while also making the force between the crushing device and the cup assembly small so as not to affect the normal operation of the user, has become the main breakthrough point in solving the problem of the magnetic locking structure. Through continuous research and testing, the applicant discovered that the magnetic attraction between the crushing device and the cup assembly is both large and small. Through spatial and temporal disassembly, it was found that the locking state requiring a large magnetic attraction and the unlocking state requiring a small magnetic attraction are in different usage states. Therefore, by disassembling the locking structure of the crushing device and the cup assembly, the contradiction is avoided, thereby achieving the purpose of both large and small magnetic attraction, and achieving the effect of ensuring that the cup assembly can reliably lock the crushing device and making it convenient for the user to easily remove the crushing device.

[0055] Based on the above analysis, the applicant has changed the existing installation structure of direct magnetic locking between the crushing device and the cup body assembly on the basis of the non-contact transmission solution, and set the locking device to have different locking positions in different working states. In order to solve the above technical problems and achieve the technical effect of both secure locking and convenient operation, the present application provides a stable and reliable food processing machine, which includes a machine base and a cup body assembly that is detachably placed on the machine base, a motor and an active magnetic disk assembly driven by the motor are provided in the machine base, the cup body assembly is provided with a cup body for holding processed materials, a crushing device is placed in the cup body, the crushing device is detachably mounted on the inner side of the cup bottom of the cup body, the crushing device is provided with a crushing piece and a driven magnetic disk assembly, the driven magnetic disk assembly and the active magnetic disk assembly are magnetically attracted to each other and realize power transmission, and since there is no need for a power transmission through-hole, the bottom of the cup body assembly is set to be completely closed. The crushing device is detachably arranged on the inner side of the bottom of the cup body. On the one hand, the food to be processed is usually located at the bottom of the cup body. On the other hand, the crushing device located at the bottom can fit closer to the active disk assembly of the machine base, which makes the magnetic attraction between the active disk assembly and the driven disk assembly stronger. Furthermore, the crushing device is further provided with an internal magnetic part, and the cup body assembly is provided with a locking device located on the outside of the cup body. The locking device is provided with an external magnetic part. The external magnetic part and the internal magnetic part are arranged relative to each other and magnetically attracted to each other, so that the crushing device is fixed to the bottom of the cup by using the external magnetic part. Although the active disk assembly and the driven disk assembly are both provided with magnets, and there is a sufficiently strong magnetic attraction between the two magnets, since the active disk assembly and the driven disk assembly are used to achieve power transmission, the two need to rotate to work, and it is not suitable to reuse the active disk assembly and the driven disk assembly to lock the crushing device. Therefore, a separate inner magnetic part is provided in the pulverizing device, and the mutual magnetic attraction between the inner magnetic part and the outer magnetic part is utilized to ensure that the locking device can securely lock the pulverizing device at the bottom of the cup body. The locking device is further provided with an operating part, which is provided at the bottom of the cup body assembly and extends out of the outer side wall of the cup body assembly, so that one end of the operating part is connected to the outer magnetic part and the other end is exposed to the outside and can be operated by the user. Thus, the user can drive the outer magnetic part away from the inner magnetic part by operating the operating part, thereby rapidly weakening the magnetic attraction between the outer magnetic part and the inner magnetic part, thereby achieving the purpose of unlocking the pulverizing device. The locking structure is utilized to reliably lock the pulverizing device in the cup body assembly. During the use of the food processor, the pulverizing device can be stably and securely fixed in the cup body assembly without having to worry about the pulverizing device flying or falling off, thereby improving safety.When the user needs to remove the pulverizer, they simply operate the operating member, pushing the outer magnetic member away from the inner magnetic member, causing the locking mechanism to unlock the pulverizer. This allows the user to conveniently remove the pulverizer from the cup assembly without being affected by the magnetic attraction between the outer and inner magnetic members, making operation quicker and more convenient. This ensures a sufficiently strong magnetic attraction between the pulverizer and the cup assembly, ensuring the pulverizer is securely locked. Furthermore, when the user needs to remove the pulverizer, the magnetic attraction between the outer and inner magnetic members can be disengaged or weakened, allowing for easy operation. Of course, it should be noted that even if the distance between the outer and inner magnetic members increases, the magnetic attraction between them remains. The main forces a user overcomes when operating the pulverizer include the pulverizer's gravity, the magnetic attraction between the outer and inner magnetic members, and the frictional force exerted on the pulverizer by the cup assembly. The gravity and frictional forces exerted on the pulverizer are relatively stable, and the frictional force exerted on the pulverizer is relatively small relative to the gravity, making it negligible to the user's perception. The force between the outer magnetic part and the inner magnetic part in the locked position is usually greater than the gravity of the pulverizing device, so as to ensure the stability and reliability of the pulverizing device; when the outer magnetic part is in the unlocked position, the magnetic attraction between the outer magnetic part and the inner magnetic part is rapidly weakened due to the change in distance. At this time, the magnetic attraction can be ignored relative to the gravity of the pulverizing device. Therefore, the user will not feel the magnetic attraction, and the gravity of the pulverizing device itself is predictable to the user. Ultimately, the user can easily pick up the pulverizing device.

[0056] Specifically, such as Figures 1-11As shown, the present application provides a stable and reliable food processing machine, which includes a base 100 and a cup assembly 110. The base 100 is provided with a motor 101 and an active disk assembly 102 driven by the motor 101, and the active disk assembly 102 is disposed on the upper portion of the base 100. The cup assembly 110 is detachably mounted above the base 100 and includes a cup body 120, a crushing device 2, and a locking device 3. Since the cup body 120 does not need to be provided with a through hole at the bottom, it can be provided in various ways. For example, the cup body 120 can be made of an integral stainless steel, or the cup body 120 can be made of an integral glass or ceramic material. Preferably, the cup body 120 includes a main body 121 and a knife disc 122. The main body 121 is made of cylindrical glass and includes an opening communicating with the upper and lower parts. A knife disc 122 is provided at the bottom opening of the main body 121. The knife disc 122 is made of stainless steel and closes the bottom opening of the main body 121. At the same time, a heating tube is provided on the outside of the knife disc 122 to heat the cup body assembly. The pulverizing device 2 includes a pulverizing element 21, a driven magnetic disk assembly 22, and an internal magnetic element 23. The driven magnetic disk assembly 22 is connected to the pulverizing element 21. The cup assembly 110 is mounted on the machine base 100. When the food processor is in operation, the active magnetic disk assembly 102 rotates under the drive of the motor 101, synchronously driving the driven magnetic disk assembly 22 to rotate and drive the pulverizing element 21 to cut and pulverize the food in the cup assembly. The internal magnetic element 23 and the locking device 3 are magnetically coupled to each other. As a result, the locking device 3, which is located outside the cup body, locks the pulverizing element 2 located inside the cup body through the internal magnetic element 23. The locking device 3 includes an external magnetic element and an operating member 33. The external magnetic element and the internal magnetic element 23 are magnetically coupled to each other to lock or unlock the pulverizing element 2. Since the main purpose of the outer magnetic part and the inner magnetic part is to lock the pulverizing device, the magnetic attraction between the outer magnetic part and the inner magnetic part only needs to be able to overcome the maximum external force applied to the pulverizing device. Therefore, the outer magnetic part and the inner magnetic part can be provided with permanent magnets at the same time to provide a greater magnetic attraction. Of course, one of the outer magnetic part and the inner magnetic part can be provided with a permanent magnet and the other can be provided with a magnetic part, which only attracts the permanent magnet. It is not necessary for both to be provided with permanent magnets at the same time. Furthermore, the outer magnetic part and the inner magnetic part provided with permanent magnets can also be provided with a single permanent magnet or multiple permanent magnets according to the requirements of the magnetic attraction. The operating member 33 is provided at the bottom of the cup body assembly and extends out of the outer side wall of the cup body assembly. Since the outer magnetic part and the inner magnetic part are located together at the bottom of the cup body assembly, the operating member is provided at the corresponding bottom and can be directly connected to the outer magnetic part. The other end of the operating member directly extends out of the outer side wall of the bottom of the cup body assembly. The user can directly operate the operating member to push the outer magnetic part, which is more convenient and direct.

[0057] By utilizing the locking device and the inner magnetic part, the crushing device can be securely fixed to the inner bottom of the cup body assembly under normal conditions, thereby realizing normal processing of the crushing device. When the crushing device needs to be removed, the user only needs to operate the operating part to push the outer magnetic part away from the inner magnetic part, thereby unlocking the crushing device and allowing the user to conveniently remove the crushing device. The locking device and the inner magnetic part are provided to realize different functions in different operating periods to meet the different needs of users. In this way, the locking device provides a sufficiently large magnetic attraction force for the crushing device to ensure the stability and reliability of the crushing device, and can also achieve a weakened magnetic attraction force to facilitate the user to directly pick up the crushing device. The user only needs to directly operate the operating part to conveniently and efficiently switch the locking device between different working states, thereby resolving the technical contradictions existing in the prior art, and ultimately providing users with a food processor that is stable and reliable during operation and easy to operate during use.

[0058] As a specific embodiment of the stable and reliable food processing machine described in this application, Figures 1-8 As shown, the food processor includes a base 100 and a cup assembly 110. The base 100 is provided with a housing 103 and a motor 101 located within the housing 103. The motor shaft of the motor 101 extends out of the housing 103, and an active disk assembly 102 is disposed at the upper end of the motor shaft. The cup assembly 110 is detachably mounted on the upper end of the base 100. Preferably, a mounting platform is provided on the upper end of the base 100, and the cup assembly 110 is mounted on the upper end of the base 100 via the mounting platform. The cup body assembly 110 includes a cup body 120, a cutter disc 122, a crushing device 2 and a locking device 3. The cup body 120 preferably includes a main body 121 and a cutter disc 122. The main body 121 is made of cylindrical glass and has upper and lower openings. The cutter disc 122 is preferably made of stainless steel and closes the lower opening of the main body 121. The main body 121 and the cutter disc 122 constitute a complete cup body 120, and a processing cavity is formed inside the cup body 120.

[0059] The crushing device 2 is detachably arranged at the bottom of the inner side of the cup body 120. Preferably, the bottom of the cutter disc 122 is provided with a cutter disc sink 123 extending downward. The crushing device 2 is arranged in the cutter disc sink 123 to better limit the crushing device 2 and prevent the crushing device 2 from being out of the transmission position during operation. The crushing device 2 includes a crushing part 21, a driven magnetic disk assembly 22 and an internal magnetic part 23. Preferably, the crushing device 2 is provided with a shell 24 that wraps the driven magnetic disk assembly 22 and the internal magnetic part 23. A cavity for accommodating the driven magnetic disk assembly 22 and the internal magnetic part 23 is formed in the shell 24, so that external processed food and liquid cannot directly contact the driven magnetic disk assembly 22 and the internal magnetic part 23, thereby preventing the driven magnetic disk assembly 22 and the internal magnetic part 23 from being corroded and rusted when in direct contact with liquid. The driven disk assembly 22 is connected to the pulverizer 21 via a blade shaft 221. The blade shaft 221 passes through the housing 24 to connect the driven disk assembly 22 and the pulverizer 21. Preferably, the driven disk body 221 is provided with a permanent magnet to magnetically engage with the active disk assembly 102. The housing 24 has an inner receiving chamber 25 formed therein. The inner magnetic member 23 is disposed within the inner receiving chamber 25. Preferably, the inner magnetic member 23 is annular and surrounds the outer circumference of the driven disk assembly 22. Axially, the inner magnetic member 23 and the driven disk assembly are both close to the bottom wall of the housing 24. Since the driven disk assembly 22 needs to rotate, a certain gap is required between it and the bottom wall of the housing 24. However, since the inner magnetic member 23 does not need to rotate, it can directly engage with the bottom wall of the housing 24. This can reduce the distance between the inner magnetic member and the outer magnetic member, and between the driven disk assembly and the active disk assembly, thereby increasing the magnetic attraction between them.

[0060] Preferably, Figure 1 、 Figure 2 and Figure 4As shown, the cup assembly 110 is further provided with a cup housing 124 and a cup support 4 on the outside of the cup body 120. A mounting space for mounting the locking device 3 is formed between the cup housing 124, the cup body 120, and the cup support 4. The locking device 3 includes an external magnetic member and an operating member 33. The external magnetic member includes an external magnet 31 and a mounting support 32. Preferably, the mounting support 32 is provided with a mounting cavity 324 for mounting the external magnet 31. The cup assembly 110 is provided with an upper cover 34 and a lower cover 35 that interlock within the mounting space. The upper cover 34 and the lower cover 35 are annular and are coaxially arranged with the pulverizing device 2. The upper cover 34 has an upper cover inner cavity 347, and the lower cover 35 has a lower cover inner cavity 352. The upper cover inner cavity 347 and the lower cover inner cavity 352 form a storage space for the external magnetic member. The external magnetic member is the same annular shape as the upper cover 34 and the lower cover 35 to be accommodated within the storage space. The bottom of the cup support 4 is also provided with a transmission cavity 41. The upper and lower covers 34, 35, and the external magnetic member surround the outer circumference of the transmission cavity 41. When the cup assembly 110 is mounted on the base 100, the active disk assembly 102 is inserted into the transmission cavity 41 so as to be close to the bottom wall of the cutter head 122, allowing the active disk assembly 102 to be close to the driven disk assembly 22 for better power transmission. The upper and lower covers 34, 35, and the external magnetic member are sleeved around the outer circumference of the transmission cavity 41. When the active disk assembly 102 is inserted into the mounting cavity 41, the external magnetic member surrounds the outer circumference of the active disk assembly 102. Preferably, a plurality of external magnets 31 are provided on the mounting support 32, and the plurality of external magnets 31 are evenly distributed around the circumference of the mounting support 32. For example, the number of external magnets 31 may be two, three, four, five, six, etc. Depending on the number, the size of the external magnets 31 can be adjusted to accommodate the space available. Preferably, the magnetic poles of the outer magnet 31 and the inner magnetic member 23 are arranged relative to each other along the axial direction of the cup body assembly 110, and the magnetic poles of the multiple outer magnets 31 at one axial end are the same. This arrangement allows the active disk assembly and the driven disk assembly, the outer magnetic member and the inner magnetic member, to achieve better alignment and proximity, ensuring that the two sets of magnetic members have maximum magnetic attraction when they are installed. The magnetic poles of the outer magnetic member and the inner magnetic member are arranged axially. When the inner magnetic member and the outer magnetic member overlap axially, they can have maximum magnetic attraction to ensure the secure installation of the crushing device. When the outer magnetic member and the inner magnetic member are misaligned or the distance between them is increased, the magnetic attraction between the inner magnetic member and the outer magnetic member can be quickly weakened, making it easier to remove the crushing device. Furthermore, the magnetic poles arranged axially can also reduce the impact on the active disk assembly and the driven disk assembly. Similarly, the magnetic poles of the active disk assembly and the driven disk assembly are arranged axially, which can also reduce the impact on the outer magnetic member and the inner magnetic member.

[0061] like Figure 2-Figure 8 As shown, the lower cover 35 is fixedly mounted on the cup body bracket 4 via a fixing platform 351. The cup body bracket 4 is provided with a bracket mounting platform 431 for fixing the fixing platform 351. The bracket mounting platform 431 is provided with a bracket guide column 432. Preferably, the lower cover 35 is fixedly connected to the fixing platform 351 and the bracket guide column 432 by screws. The lower cover 35 is also provided with a first retaining rib 353, a second retaining rib 354, and a guide column 355. A first spring 51 is provided at the first retaining rib 353, and a first mounting column 356 is provided on the side wall of the first retaining rib 353 to be inserted into the first spring 51. The first mounting column 356 is inserted into the first spring 51 to limit the first spring 51. A second spring 52 is provided at the second retaining rib 354. The mounting bracket 32 ​​is provided with a guide hole 325 and a spring mounting column 326. When the mounting bracket 32 ​​is installed in the accommodating space formed by the upper cover 34 and the lower cover 35 , the guide column 355 is inserted into the guide hole 323 , and at the same time, the spring mounting column 326 is inserted into the second spring 52 so that the second spring 52 is clamped between the lower cover 35 and the mounting bracket 32 ​​.

[0062] The mounting bracket 32 ​​is also provided with a guide block 321, and the guide block 321 is provided with a guide bevel 322. The outer wall of the mounting bracket 32 ​​is provided with an avoidance groove 323. The upper cover is provided with a guide groove 344 that cooperates with the guide block 321, and the guide groove 344 is provided with an inclined surface 345 that cooperates with the guide bevel 322. The guide block 321 is located in the guide groove 344. When the upper cover 34 is pushed, the guide bevel 322 cooperates with the inclined surface 345 to convert the rotational motion of the upper cover 34 into the vertical motion of the mounting bracket 32 ​​along the axial direction, thereby driving the outer magnet 31 to move closer to or away from the inner magnetic part 23. A limiting rib 346 is also provided below the upper cover 34. When the upper cover 34 and the lower cover 35 are buckled together, the other end of the first spring 51 abuts against the limiting rib 346.

[0063] The upper cover 34 also has a connecting platform 341. The connecting head 341 has a rotation-stop groove 343 and a connecting hole 343. The operating member 33 has a rotation-stop rib 332 that cooperates with the rotation-stop groove 343, and a connecting boss 333 that cooperates with the connecting hole 343. The operating member 33 is also provided with a handle 331 on the outside of the cup body assembly 110. The cup body bracket 4 also has a bracket limiting groove 433, and the side wall of the cup body shell 124 is provided with an operating hole 125. The operating member 33 passes through the bracket limiting groove 433 and the operating hole 125 and reciprocates within the bracket limiting groove 433 and the operating hole 125.

[0064] like Figure 5 As shown, when the inclined surface 345 of the guide groove 344 does not press the guide block 321, the second spring 52 pushes the mounting bracket 32 ​​and drives the external magnet 31 to approach the top of the upper cover 34, so as to approach the cutter disc 122 and the internal magnetic member 23 located in the cutter disc 122. At this time, the distance between the external magnet 31 and the internal magnetic member 23 is close, and the external magnet 31 and the internal magnetic member 23 have a sufficiently strong magnetic attraction force to reliably lock the crushing device 2 in the cup body assembly 110. Figure 6 As shown, by operating the handle 331, the operating member 33 is driven, ultimately pushing the upper cover 34 to rotate at the bottom of the cup assembly 110. The inclined surface 345 of the upper cover 34 applies a force F to the guide bevel 322. This force F is decomposed into a downward force F1 on the guide block 321. Under the pressure of this force F1, the guide block 321 drives the mounting bracket 32 ​​and the outer magnet 31 downward. At this time, the distance between the outer magnet 31 and the inner magnetic member 23 is increased, causing the magnetic attraction between the outer magnet 31 and the inner magnetic member 23 to rapidly decrease, making it easier for the user to pick up the pulverizing device 2. During the rotation of the upper cover 34, the retaining rib 346 rotates within the space of the avoidance groove 323 and compresses the first spring 51. The mounting bracket 32 ​​compresses the second spring 52 through the spring mounting groove 326 and moves axially under the guidance of the guide column 355 and the guide hole 325. Under the reaction force of the first spring 51 and the second spring 52, when the operating member 33 is released, the first spring 51 and the second spring 52 push the mounting bracket 32 ​​and the upper cover 34 back to Figure 5 Shown in locked position.

[0065] The locking device is provided, utilizing its external magnetic member to secure the pulverizing device when needed, thereby stably adhering the pulverizing device to the cup assembly. When the user desires to remove the pulverizing device, they simply operate the operating member to move the external magnetic member away from the internal magnetic member, thereby releasing the magnetic attraction between the external and internal magnetic members, making it easier for the user to remove the pulverizing device. Furthermore, under the action of the elastic member, when the user releases the operating member, the locking device returns to its locked position. Because the pulverizing device is operated at different stages, the locking device can be relied upon to apply different forces to the pulverizing device at different stages, achieving both a sufficiently secure locking force and a reduced force applied to the pulverizing device. By utilizing the different states of the locking device at different stages, the force distribution between the locking device and the pulverizing device is decomposed, resolving any conflicts between the two, and providing the user with a conveniently operated food processor. Of course, since the pulverizing device can be unlocked by pushing the top rod and driving the external magnetic part to move, the user can also unlock the pulverizing device by pressing the top rod by himself during use, for example, when the user needs to take the pulverizing device while holding the cup body assembly, so that the pulverizing device can be easily removed.

[0066] It is understandable that the operating member can also be directly connected to the mounting bracket without providing the upper cover and the lower cover. The operating member drives the mounting bracket and the external magnet to rotate circumferentially so that the external magnet and the internal magnetic member are misaligned and the magnetic attraction distance is increased.

[0067] It is understood that the external magnetic member may be provided solely as a magnetic member, the external magnetic member being directly disposed within the accommodation space formed by the upper and lower covers, with the upper cover being used to drive the external magnetic member to move axially. Alternatively, the locking device may be provided solely as an external magnetic member and an operating member, the external magnetic member being provided solely as an external magnet, with the operating member directly driving the external magnet toward or away from the internal magnetic member.

[0068] It can be understood that the external magnet and the internal magnetic part are both provided with a plurality of relative magnets, the magnetic poles of the magnets are arranged along the axial direction, and the relative magnetic poles attract each other. Among them, the magnetic poles of the multiple external magnets of the external magnetic part are staggered, that is, in the axial direction, when the magnetic pole at the upper end of one external magnet is the N pole, the magnetic pole at the upper end of the adjacent external magnet is the S pole, and the magnetic pole at the upper end of the adjacent external magnet is the N pole, and so on. With such an arrangement, when the external magnetic part and the internal magnetic part are in the locked position, the adjacent magnetic poles attract each other to lock the crushing device to the bottom of the cup body; when the external magnetic part is moved and rotated by the pushing action of the operating part, the magnetic repulsion between the dislocated external magnet and the internal magnetic part occurs, so that the external magnetic part can push the internal magnetic part and push the crushing device to move upward or have a tendency to move, making it more convenient for the user to remove the crushing device. Alternatively, since the crushing device is detachably arranged in the cup body assembly, the crushing device can be limited by utilizing the staggered magnetic poles of the external magnetic part and the internal magnetic part to ensure that the crushing device is in a preset direction; the external magnetic part can be moved downward to increase the distance from the internal magnetic part to unlock the crushing device.

[0069] It can be understood that based on the shape changes of the active disk assembly and the driven disk assembly, the inner magnetic part and the driven disk assembly can be set at different positions. For example, the active disk assembly and the driven disk assembly are nested with each other at the bottom of the cup assembly, such as the active disk assembly is nested on the outer periphery of the driven disk assembly. At this time, the inner magnetic part and the outer magnetic part are nested with each other accordingly, and the inner magnetic part and the outer magnetic part can be located above the active disk assembly and the driven disk assembly; or, the inner magnetic part and the outer magnetic part can also be located below the active disk assembly and the driven disk assembly. The outer magnetic part moves radially away from or closer to the inner magnetic part; or, the outer magnetic part can move axially away from or closer to the inner magnetic part.

[0070] It is understandable that since magnets, particularly permanent magnets, are disposed between the inner and outer magnetic members, the active disk assembly, and the driven disk assembly, a magnetic attraction force exists between them. Therefore, the resetting of the outer magnetic member can also directly rely on the inner magnetic member, or even directly rely on the active disk assembly or the driven disk assembly, without the need for a spring to push the outer magnetic member to reset. Alternatively, a permanent magnet or electromagnet can also be disposed at the bottom of the cup assembly to push the outer magnetic member to reset.

[0071] As another preferred embodiment of the stable and reliable food processing machine described in this application, Figures 9-11 As shown, the locking device includes a manipulation member and an outer magnetic member. The outer magnetic member reciprocates along the axial direction of the cup assembly to approach or move away from the inner magnetic member.

[0072] The operating member 33 is disposed at the bottom of the cup body assembly 110. The bottom of the cup body bracket 4 is provided with a bracket guide column 432. The operating member 33 is provided with a push guide groove 334. The bracket guide column 432 is inserted into the push guide groove 334. The operating member 33 is axially fixed to the cup body bracket 4 by screws or other fixing members, so that the operating member 33 can reciprocate along the extension direction of the push guide groove 334. The side wall of the cup body shell 124 is provided with an operating hole 125 for the operating member 33 to extend. The cup body bracket 4 is also provided with a third spring 53 for pushing the operating member 33 to return. A handle 331 is provided at the outer end of the operating member 33. Pressing the handle 331 can push the operating member 33 to move radially inward along the cup body assembly; under the pushing action of the third spring 53, the operating member 33 returns to its original position. The radial travel range of the operating member 33 is limited by the pushing guide groove 334 . Therefore, the travel range of the operating member 33 can be adjusted by adjusting the radial extension length of the pushing guide groove 334 .

[0073] The external magnetic parts 6 are provided in two pieces and are symmetrically arranged at the bottom of the cup body assembly 110. The bottom of the cup body assembly 110 is also provided with a transmission cavity 41 for the active disk assembly to extend into. The two external magnetic parts 6 are clamped on both sides of the transmission cavity 41. The external magnetic part 6 includes an external magnet and a mounting bracket 61. Preferably, the external magnetism is embedded in the mounting bracket 61, and the mounting bracket 61 is used to protect the external magnetism. The mounting bracket 61 includes a bracket sliding plate 62 and a bracket support plate 64. The bracket support plate 64 is fan-shaped. The external magnet is embedded in the bracket support plate 64 and is arranged opposite to the internal magnetic part 23. The bracket sliding plate 62 is located radially outside the bracket support plate 64. Preferably, the bracket support plate 64 is symmetrically arranged, and the bracket sliding plate 62 is located on the symmetrical center plane of the bracket support plate 64, so that the mounting bracket 61 is symmetrical on both sides. The bracket sliding plate 62 is provided with a bracket guide groove 63. The bottom of the cup holder 4 is further provided with a bracket guide post 432 for limiting the mounting bracket 61. The bracket guide post 432 is inserted into the bracket guide groove 63 and is fixed to the cup holder 4 along the axial direction by means of screws or other fixing members, so that the mounting bracket 61 can reciprocate along the extension direction of the bracket guide groove 63. Preferably, a spring is further provided between the cup holder 4 and the mounting bracket 61.

[0074] The side wall of the bracket support plate 64 is provided with a bracket sliding surface 641, and the end of the operating member 33 close to the mounting bracket 61 is provided with a push plate 335, and one side of the push plate 335 is provided with a push surface 336, and the push surface 336 abuts against the bracket sliding surface 641. Figure 10 As shown, when the operating member 33 is not pushed by an external force, the operating member 33 and the mounting bracket 61 are acted upon by the spring, pushing the mounting bracket 61 to a position close to the center of the cup assembly so as to be opposite to the inner magnetic member, thereby locking the crushing device. Figure 11 As shown, the operating member 33 is subjected to external squeezing force, the pushing guide groove 334 and the bracket mounting rod 432 limit the operating member 33, and the operating member 33 moves radially inward. The pushing surface 336 abuts against the bracket sliding surface 641, and converts the radial inward pushing force of the operating member 33 into a radial outward pushing force of the mounting bracket 61. Under the limiting action of the bracket guide groove 63 and the bracket guide column 432, the mounting bracket 61 moves radially outward to be misaligned with the inner magnetic member and increase the magnetic distance with the inner magnetic member, and the crushing device is unlocked to facilitate the user to take the crushing device.

[0075] The operating member and the external magnetic member are directly provided, and the operating member is exposed on the outer side wall of the cup body assembly. When the user needs to take the pulverizing device, the operating member can be directly operated to drive the external magnetic member to unlock the pulverizing device, making it convenient for the user to take it. When the user does not need to operate the pulverizing device, the external magnetic member can reliably lock the pulverizing device inside the cup body assembly, preventing the pulverizing device from flying or falling off, thereby ensuring the safety of the food processor. With such an arrangement, the pulverizing device has different locking states in different time periods of use, resolving the contradiction caused by the simultaneous requirement of locking and unlocking states in the prior art, and achieving both a sufficiently strong magnetic locking force and the elimination of the magnetic locking force to facilitate user taking, ultimately providing the user with a food processor with stable and reliable transmission. At the same time, the locking device can also be set with different locking methods and position arrangements according to different cup body assembly structures, so as to meet the structural requirements of different food processors.

[0076] It is understandable that the operating member and the external magnetic member may also be directly mounted on the outer side wall of the cutter disc without providing the cup body bracket.

[0077] It can be understood that the guide groove of the mounting bracket is arranged along the circumference, the operating member pushes the mounting bracket, and the mounting bracket reciprocates along the circumference of the cup body assembly to approach or move away from the inner magnetic member to lock or unlock the crushing device.

[0078] It can be understood that a rotating mounting column is set between the operating member and the cup body assembly so that the operating member can be rotated back and forth along the rotating mounting column, pushing the operating member to rotate and further pushing the outer magnetic member to move radially or circumferentially to approach or move away from the inner magnetic member.

[0079] The above description is merely a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. That is, all equivalent changes and modifications made according to the present application are covered by the scope of the claims of the present application and will not be listed one by one here.
