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] Furthermore, the prior art can also provide a mutually magnetic magnet assembly between the detachable tool and the cup body for the detachable non-contact transmission contact, so as to adsorb the tool to the cup body to prevent the tool from falling off from the cup body.

[0006] However, such a solution still has technical defects for users: for the solution using a mechanical fixing structure, on the one hand, it will increase the friction of the mechanical fixing structure; on the other hand, when operating the tool, the user must first release the fixing structure before further removing the tool from the cup body, which makes the operation cumbersome, and the complex fixing structure also brings inconvenience to cleaning. Although the magnetic attraction structure using magnets can solve the problem of complex mechanical structure, if the magnetic attraction force between the magnetic attraction structures is insufficient, the tool will still fall off from the cup body, and if the magnetic attraction force is too large, the user will need to overcome the large magnetic attraction force when removing the tool, which will also bring inconvenience to the operation. As a result, there is a contradiction between the safety and ease of use of the magnetic attraction structure. The existing solutions usually adopt a compromise solution, that is, to partially sacrifice the user's convenience while ensuring safety as much as possible. Summary of the Invention

[0007] The purpose of the present utility model is to provide a food processing machine that is easy to operate, so as to solve the technical problem in the prior art that when a magnetically driven crushing device is detachably arranged in a cup body, sufficient safety protection can be ensured in the cup body, and no reaction force is generated when the user operates it, so that the user can easily remove the crushing device, thereby solving the installation contradiction between requiring a large interaction force and a small interaction force.

[0008] In order to solve the above technical problems, the present application provides a food processor that is easy to operate, wherein the food processor includes a machine base, which is provided with a motor and an active magnetic disk assembly driven by the motor; a cup body assembly, which is detachably mounted on the machine base, and the cup body assembly includes a cup body, a crushing device arranged in the cup body and detachably mounted on the inner side of the cup bottom; the crushing device includes a crushing part, a driven magnetic disk assembly that is attracted to the active magnetic disk assembly and drives the crushing part to work under the drive of the active magnetic disk assembly, and an internal magnetic part; a locking device, which is arranged outside the cup body for locking and unlocking the crushing device, includes an external magnetic part that is magnetically attracted to the internal magnetic part and is movable, and a push rod that pushes the external magnetic part to move; wherein the push rod is arranged at the bottom of the cup body assembly, and the push rod protrudes downward from the lower end surface of the cup body assembly. The push rod is pressed and moved by the bearing surface to push the external magnetic part away from the internal magnetic part.

[0010] Preferably, the external magnetic component includes an external magnet and a mounting bracket for mounting the external magnet, the mounting bracket is movably mounted on the bottom of the cup body assembly, and the push rod pushes the mounting bracket to move the external magnetic component away from the internal magnetic component.

[0011] Preferably, a guide rail and a slider that slide in radial direction are provided between the mounting bracket and the cup body assembly, and the push rod moves axially and drives the mounting bracket to move radially away from the inner magnetic component.

[0012] Preferably, a push surface and a sliding surface that cooperate with each other are further provided between the push rod and the mounting bracket, and the included angles between the push surface and the sliding surface and the push rod and the mounting bracket are all acute angles.

[0013] Preferably, there are at least two external magnetic members and they are symmetrically arranged at the center of the bottom of the cup body assembly.

[0014] Preferably, a guide rail and a slider that slide in an axial direction are provided between the mounting bracket and the cup body assembly, and the push rod moves in the axial direction and drives the mounting bracket to move axially away from the inner magnetic component.

[0015] Preferably, the locking device further comprises a connecting rod located between the outer magnetic member and the push rod, and the push rod pushes the outer magnetic member away from the inner magnetic member through the connecting rod.

[0016] Preferably, a transmission cavity is provided at the bottom of the cup body assembly for the active magnetic disk assembly to extend into, and the external magnetic component is arranged on the periphery of the transmission cavity.

[0017] Preferably, the crushing device includes a shell that wraps the driven magnetic disk assembly and the inner magnetic part, the inner magnetic part is arranged on the outer periphery of the driven magnetic disk assembly and close to the bottom wall of the shell, the outer magnetic part is arranged on the outside of the bottom wall of the cup body and the magnetic poles of the outer magnetic part and the inner magnetic part are arranged axially opposite to each other.

[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 non-contact transmission, and adopts an active magnetic disk assembly and a driven magnetic disk assembly that are magnetically attracted to each other to realize power transmission between the motor and the crushing part, fundamentally avoiding the crushing part from transmitting vibration and noise to the motor during operation. The crushing device is detachably arranged at the bottom of the cup, which allows the crushing device to fully fit the bottom of the cup, so that it can be close to the active magnetic disk assembly of the machine base to reduce the distance between the active magnetic disk assembly and the driven magnetic disk assembly, and enhance the magnetic attraction between the active magnetic disk assembly and the driven magnetic disk assembly. On the basis of the above, the cup body assembly further provides a locking device on the outside of the cup body that is magnetically attracted to the crushing device. The locking device can be magnetically attracted to the internal magnetic part in the crushing device to prevent the crushing device from falling out of the cup body when not operated by the user. The applicant further analyzed and found that, for the pulverizing device and the cup assembly, when the user operates the cup assembly, for example, when pouring out the slurry in the cup assembly, the pulverizing device is not operated synchronously. When the pulverizing device is operated, the cup assembly is usually placed on a workbench and does not need to be operated. In other words, although the pulverizing device is detachably installed in the cup assembly, it is necessary to have sufficient limiting force to prevent the pulverizing device from falling off, and to avoid excessive limiting force to facilitate the user to remove the pulverizing device. However, the above-mentioned contradiction occurs at different stages of the user's use. Therefore, it is only necessary to set different limiting forces between the cup assembly and the pulverizing device at different stages of the user's operation to simultaneously meet the limiting requirements of having a sufficiently strong force but not having a sufficiently large force.

[0020] Therefore, the present invention provides a locking device in the cup assembly, which includes an external magnetic member and a push rod. The external magnetic member can magnetically attract the internal magnetic member in the pulverizing device, utilizing the magnetic attraction between the two to ensure that the pulverizing device can be stably and reliably installed in the cup assembly. When the user normally operates the cup assembly, there is no risk of the pulverizing device falling off, ensuring that the food processor is safer and more reliable. The top rod protrudes downward from the lower end surface of the cup body assembly at the bottom, and the top rod can push the external magnetic part. When the user needs to remove the crushing device, it is usually not necessary to operate the cup body assembly at the same time. At this time, the cup body assembly is in a non-working state and is usually placed freely on the workbench. The table top of the workbench will abut against the exposed top rod to form a bearing surface that can press the top rod. Under the action of the gravity of the cup body assembly, the workbench applies a reaction force to the cup body assembly, and the bearing surface presses the top rod to shrink into the cup body assembly, so that the top rod pushes the external magnetic part, so that the external magnetic part moves away from the internal magnetic part, and the magnetic attraction of the external magnetic part to the internal magnetic part is exerted. At this time, the crushing device will no longer be subjected to additional additional force and can be easily removed from the cup body assembly, which is convenient for the user's direct operation. The driven disk assembly is provided with a transmission permanent magnet to magnetically attract the active disk assembly for transmission; the external magnetic part is provided with an external magnet to magnetically attract the internal magnetic part, wherein the magnetic poles of the external magnet and the transmission permanent magnet extend in the same direction, that is, when the magnetic poles of the transmission permanent magnet extend axially, the magnetic poles of the external magnet extend axially accordingly. This arrangement can avoid the influence of the active disk assembly and the driven disk assembly on the external magnetic part and the internal magnetic part, and provide reliability of the external magnetic part locking the crushing device. It should be noted that since the external magnetic part and the internal magnetic part only need to lock the crushing device by magnetic attraction and do not require power transmission, the external magnetic part and the internal magnetic part do not need to be provided with permanent magnets at the same time.

[0021] Here, the non-working free placement refers to the state when the cup body assembly is not in a working state, is not directly mounted on the machine base, and the user does not need to pick up the cup body assembly, and the cup body assembly is placed normally on a workbench such as a kitchen countertop. At this time, the external workbench is usually a horizontal table, and forms a bearing surface for placing the cup body assembly. Therefore, the top rod exposed on the lower end surface of the cup body assembly first contacts the table. When the user completely disengages from the cup body assembly, the gravity of the cup body assembly will compress the top rod, and under the reaction push of the workbench, the top rod will be compressed and retracted into the cup body assembly. During the retraction process, the user does not need to perform additional operation or compression.

[0022] Of course, even if the user operates the cup body assembly while operating the crushing device, for example, the crushing device is removed when cleaning the cup body assembly, and the crushing device is not necessarily placed on the workbench at this time, then the user can directly operate the top rod to move the external magnetic part away from the internal magnetic part; or, the user can also place the cup body assembly on the workbench and then remove the crushing device. Since the top rod directly protrudes from the lower end surface of the cup body assembly, the user can also directly touch it when operating it directly. Among them, when the cup body assembly contains slurry, if the user places the cup body assembly on the workbench, although the top rod pushes the external magnetic part away from the internal magnetic part, so that the crushing device has no limiting force, the user cannot operate the crushing device at this time, and the crushing device can also be safely and reliably placed freely at the bottom of the cup body assembly under the action of its own gravity, without any risk. When the user picks up the cup assembly to pour out the slurry, the external force of the push rod disappears, the push rod and the external magnetic part return to the locked state, and the crushing device is locked. In this way, even if the cup assembly is tilted, there is no risk of the crushing device falling off.

[0023] 2. The push rod is configured to protrude downward from the lower end surface of the cup assembly, so that when the cup assembly is placed on the machine base, the push rod can also abut against the machine base. For a properly operating food processor, at this time, the cup assembly and the pulverizing device are both properly placed, and there is no risk of the pulverizing device itself falling off. In addition, there is a stronger magnetic attraction between the driven magnetic disk assembly of the pulverizing device and the active magnetic disk assembly of the machine base, which can also better restrain the pulverizing device. Therefore, the push rod protruding from the lower end surface of the cup assembly does not affect the normal operation of the food processor.

[0024] However, when the cup assembly is placed on the base to achieve transmission, the active and passive disk assemblies must be aligned with high precision. The reaction force of the ejector pin can affect the precise alignment of the cup assembly and the base, thereby reducing the operational stability between the cup assembly and the base and easily generating vibration and noise. Furthermore, although the active and passive disk assemblies have a stronger magnetic attraction, if the passive disk assembly becomes stuck during operation, the active and passive disk assemblies cannot rotate synchronously, potentially causing magnetic pole repulsion. The active disk assembly can push the passive disk assembly away from its operating position, thus affecting the normal transmission between the active and passive disk assemblies.

[0025] Therefore, a relief hole for accommodating the push rod is provided in the machine base. When the cup body assembly is placed on the machine base, the push rod freely extends into the relief hole and does not come into direct contact with the machine base. Consequently, the push rod will not be subjected to a compressive force to push the external magnetic component upward. The external magnetic component can also always lock and limit the crushing device. In this way, the push rod will not affect the normal installation of the cup body assembly and the machine base, allowing the cup body assembly and the machine base to be accurately aligned. At the same time, the external magnetic component can also strengthen the position limitation of the crushing device. In particular, the external magnetic component and the internal magnetic component usually do not need to rotate with the driven disk assembly. Even if the driven disk and crushing component become stuck and receive a reverse thrust from the active disk assembly, the external magnetic component and the internal magnetic component can still limit the crushing device to a suitable transmission position, ensuring that the food processor can always be in a stable and reliable working state.

[0026] 3. The driven disk assembly and the inner magnetic component are wrapped in a shell to prevent them from leaking directly into the cup assembly. The driven disk assembly and the active disk assembly, the inner magnetic component and the outer magnetic component, all adopt a non-contact magnetic attraction method to attract each other, and the shell will not affect the normal operation of the two modules. The inner magnetic component is set 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.

[0027] 4. Similarly, 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 magnetic member and the internal magnetic member can also be maintained.

[0028] 5. Since there is no need for power transmission between the outer magnetic part and the inner magnetic part, even if only the inner magnetic part or the outer magnetic part is set as a permanent magnet, the magnetic attraction requirement between the outer magnetic part and the inner magnetic part can be met, and it can also be ensured that when the distance between the outer magnetic part and the inner magnetic part increases, the crushing device can be easily removed. In order to make the locking of the crushing device by the external magnetic part more reliable, the outer magnetic part and the inner magnetic part are usually set as permanent magnets at the same time to ensure the magnetic attraction between the two. As mentioned above, preferably, the outer magnetic part is sleeved on the outer periphery of the active disk assembly, and the inner magnetic part is sleeved on the outer periphery of the driven disk assembly, which makes the diameter and circumference of the outer magnetic part and the inner magnetic part larger. If it is set as a complete permanent magnet, the cost of the outer magnetic part and the inner magnetic part will increase and the structural stability will deteriorate. The inner magnetic part and the outer magnetic part are arranged in a ring shape and are arranged as multiple groups of permanent magnets that attract each other. For example, mounting frames can be respectively arranged in the cup body assembly and the crushing device, and multiple groups of permanent magnets can be arranged on the mounting frames to achieve mutual magnetic attraction between the outer magnetic part and the inner magnetic part. In this way, the stable and reliable installation of the crushing device can be guaranteed, the overall cost of the food processing machine can be reduced, and the structural stability of the outer magnetic part and the inner magnetic part can be improved.

[0029] 6. The outer magnetic part needs to be magnetically attracted to the inner magnetic part through a magnet. Preferably, the outer magnetic part is provided with an outer magnet and a mounting bracket. The outer magnet and the inner magnetic part are magnetically attracted to each other, and the mounting bracket is used to install the outer magnet and drive the outer magnet to move to switch between different positions. In this way, the functions of the two are separated to ensure that both the outer magnet and the mounting bracket can achieve stable and reliable operation. A sliding structure is then provided on the cup body assembly. When the push rod is subjected to an external reaction force, it can conveniently push the sliding structure to drive the outer magnet away from the inner magnetic part, thereby more conveniently and reliably achieving the separation of the outer and inner magnetic parts, and the operation is more convenient and reliable.

[0030] 7. Reliable guide rails and slides can make the sliding of the external magnet smoother and faster, and can also increase the service life of the locking device. Even after the food processor has been used for a long time, it can still ensure that the push rod can stably and reliably push the external magnetic part, thereby achieving certified and reliable operation of the food processor. Further, a pushing surface and a sliding surface are provided, which can convert the axial movement of the push rod into a force that pushes the external magnetic part in the radial direction. In particular, the angles between the pushing surface and the sliding surface and the push rod and the mounting bracket are all acute angles to ensure that the pushing force of the push rod can be applied more to the external magnetic part, so as to push the external magnetic part in the radial direction more quickly.

[0031] 8. For a food processor with a non-contact transmission, the primary function is to ensure reliable power transmission between the active and passive magnetic disk assemblies. Generally, inner and outer magnetic members for interlocking are disposed on the periphery, for example, surrounding the periphery of the active and passive magnetic disk assemblies. At least two outer magnetic members are disposed at the bottom of the cup assembly, enabling multiple circumferential arrangements of both the inner and outer magnetic members to ensure balanced magnetic locking. The inner magnetic member only needs to be fixed to the periphery of the passive magnetic disk assembly; the outer magnetic member, on the other hand, requires relative movement to lock or unlock the pulverizing device. By disposing multiple outer magnetic members, each housing an external magnet and a mounting bracket, the multiple outer magnetic members simultaneously move radially of the cup assembly away from the inner magnetic member under the push of the push rod. This ensures that multiple sets of mutually magnetically attracted outer and inner magnetic members are simultaneously unlocked or locked, thereby better ensuring that the pulverizing device is stably and reliably locked to the bottom of the cup assembly.

[0032] 9. For different cup body assemblies, there are different spaces inside. Only the push rod and the external magnetic part are provided, which cannot meet the needs of various spaces. A connecting rod is further provided between the external magnetic part and the push rod, and the connecting rod is used to transmit the force between the push rod and the external magnetic part, so that the locking device can meet more installation requirements. In particular, since the push rod can usually only be set and moved axially, and the external magnetic part has multiple movement modes, it may not be possible to directly push the external magnetic part directly driven by the push rod. The connecting rod is used to achieve the direction change of the driving force, and the axial force is converted into the directional force required by the external magnetic part. For example, the external magnetic part requires axial force, radial force, circumferential force, or even a combination of forces in multiple directions, etc., which can be achieved by the connecting rod. The connecting rod can also be set to multiple as needed to meet the pushing requirements of external magnetic parts in multiple different positions.

[0033] Furthermore, mutually cooperating pushing surfaces and sliding surfaces are provided between the connecting rod and the external magnetic part, and between the connecting rod and the push rod. When the push rod is subjected to an external reaction force, force is transmitted between the push rod and the connecting rod through the pushing surface and the sliding surface. The connecting rod further utilizes the pushing surface and the sliding surface to transmit the force to the external magnetic part, and pushes the external magnetic part away from the internal magnetic part, thereby finally unlocking the crushing device.

[0034] 10. When the cup body assembly is placed on the workbench, the push rod is compressed and pushes the outer magnetic part away from the inner magnetic part, thereby unlocking the crushing device. An elastic part is provided so that when the cup body assembly is picked up, the outer magnetic part can be promptly pushed back to the magnetic attraction position relative to the inner magnetic part to lock the crushing device, thereby improving safety and reliability. Of course, since the outer magnetic part and the inner magnetic part are in a mutually magnetic attraction relationship, and the active disk assembly and the driven disk assembly are in a mutually magnetic attraction relationship, when the crushing device is installed in place, the outer magnetic part is always under the action of magnetic attraction. Therefore, when the external force acting on the outer magnetic part disappears, the outer magnetic part can also be reset to the position locked to the crushing device under the action of the magnetic attraction force of the inner magnetic part, or even under the action of the magnetic attraction force of the driven disk assembly or the active disk assembly, without the need to add the elastic part.

[0035] 11. When the push rod is subjected to the reaction force of the workbench, it usually slides axially and is pressed into the cup body assembly. A limiting hole extending axially is provided at the bottom of the cup body assembly to limit the push rod from sliding in the limiting hole, so as to fully protect the push rod from being compressed by external force, so that it can be retracted upward into the cup body assembly in time, and further push the external magnetic part to unlock the crushing device.

[0060] 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.

[0061] 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.

[0062] 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 device 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.

[0063] 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.

[0064] 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 magnetic locking devices. 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 device 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.

[0065] Based on the above analysis, the applicant has modified the existing direct magnetic locking installation structure between the pulverizing device and the cup assembly on the basis of a 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 food processing machine that is easy to operate. The food processing machine includes a machine base and a cup assembly that is detachably placed on the machine base. A non-contact magnetic power transmission method is used between the two. The machine base is provided with a motor and an active magnetic disk assembly driven by the motor. The cup assembly is provided with a cup body for holding the processed material. Since there is no need for a power transmission through hole, the bottom of the cup body can be completely closed. The pulverizing device for cutting and processing the food is detachably arranged at the bottom inside 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 pulverizing device located at the bottom can be closer to the active magnetic disk assembly. The cup body assembly is further provided with a locking device that is magnetically attracted to the pulverizing device to lock the pulverizing device. The pulverizing device includes a pulverizing element for processing food materials, a driven disk assembly that is magnetically attracted to the active disk assembly and drives the pulverizing element to achieve pulverization processing under the drive of the active disk assembly. The driven disk assembly and the pulverizing element can achieve the pulverization processing requirements of the pulverizing device. The pulverizing device further includes an internal magnetic element. 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 magnets, since the active disk assembly and the driven disk assembly need to achieve power transmission and both need to rotate during operation, it is not suitable to reuse the active disk assembly and the driven disk assembly to lock the pulverizing device. Therefore, a separate internal magnetic element is provided in the pulverizing device, and the internal magnetic element and the locking device are magnetically attracted to each other to ensure that the locking device firmly locks the pulverizing device. The locking device is provided with an external magnetic element on the outside of the cup body, and the external magnetic element and the internal magnetic element are magnetically attracted to each other, and a top rod is provided to push the external magnetic element to move. Wherein, the push rod is arranged at the bottom of the cup body assembly, and the push rod protrudes downward from the lower end surface of the cup body assembly, thereby, when the cup body assembly is placed on the workbench, the push rod first contacts the workbench, and due to the weight of the cup body assembly itself, the push rod is pressed by the reaction force of the workbench, shrinks into the cup body assembly and pushes the external magnetic part, so that the external magnetic part is away from the original position locked with the internal magnetic part. According to Coulomb's law, the magnetic attraction between two magnets is inversely proportional to the square of the distance between the two magnets. When the distance between the external magnetic part and the internal magnetic part is increased, the magnetic attraction between the external magnetic part and the internal magnetic part will quickly weaken. The magnetic attraction between the external magnetic part and the internal magnetic part can be weakened to the point that the user is not easily aware of the interaction force when operating the crushing device.It should be noted that the non-working freely placed cup body assembly here means that the cup body assembly is not in a working state of being connected to the power of the machine base, and the user does not operate the cup body assembly or other actions, so that the cup body assembly is naturally placed on a workbench with a normal horizontal surface. The workbench here refers to a flat surface such as a kitchen countertop or desktop used by ordinary users at home, and does not refer to a countertop with a special surface for special purposes. In such a food processing machine, the cup body assembly can reliably lock the crushing device at the bottom of the cup body assembly when it is working normally and when the user is operating the slurry, ensuring the safety of the cup body assembly and the alignment between the crushing device and the active magnetic disk assembly; and when the user needs to remove the crushing device, the magnetic attraction can be weakened to facilitate the user's disassembly operation, improve user comfort, and avoid the safety risks that may be posed to the user by excessive gripping force. The solution of the present application is to directly set a push rod at the bottom of the cup body assembly. When the user needs to remove the crushing device, he only needs to place the cup body assembly freely on the workbench, and the push rod can be used to unlock the crushing device and then remove the crushing device without additional operation. When the user does not directly operate the crushing device, even if the cup body assembly is placed on the workbench and the crushing device is in an unlocked state, since the cup body assembly and the crushing device are both in a natural position at this time, there is no risk of the crushing device falling off and injuring the user. When the user picks up the cup body assembly, for example, when the user pours pulp, the push rod is separated from the reaction force of the workbench, and the locking device can lock the crushing device again, so that the crushing device is in a reliable position. In this way, there is a sufficiently large magnetic attraction force between the crushing device and the cup body assembly, which can meet the requirements of safe locking of the crushing device. When the user needs to remove the crushing device, the magnetic attraction between the crushing device and the cup body assembly can be released or weakened, and the user can operate it easily.

[0066] Specifically, such as Figures 1-15As shown, the present application provides a food processor that is easy to operate. The food processor 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. 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 disc is provided on the outside of the knife disc 122 to heat the cup body assembly. The crushing device 2 includes a crushing element 21, a driven magnetic disk assembly 22, and an internal magnetic element 23. The driven magnetic disk assembly 22 is connected to the crushing element 21. The cup body 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 to drive the crushing element 21 to work, cutting and crushing the food in the cup body assembly. The internal magnetic element 23 and the locking device 3 are magnetically coupled to each other. Thus, the locking device 3 disposed on the outside of the cup body locks the crushing device 2 located in the cup body through the internal magnetic element 23. The locking device 3 includes an external magnetic element and a push rod 33. The external magnetic element and the internal magnetic element 23 are magnetically attracted to each other. Since the main purpose of the external magnetic part and the internal magnetic part is to lock the pulverizing device, the magnetic attraction between the external magnetic part and the internal magnetic part only needs to be able to overcome the maximum external force acting on the pulverizing device. Therefore, the external magnetic part and the internal magnetic part can be provided with permanent magnets at the same time to provide a greater magnetic attraction. Of course, the external magnetic part and the internal magnetic part can also be provided with a permanent magnet, and the other can be provided as a magnetic part, which only attracts the permanent magnet. It is not necessary for both to be provided as permanent magnets at the same time. Furthermore, the external magnetic part and the internal magnetic part that are 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 push rod 33 is located at the bottom of the cup body assembly 110, and the push rod 33 at least partially protrudes downward from the lower end surface of the cup body assembly 110. When the cup body assembly 110 is in a non-working state and is placed freely, the push rod 33 first contacts the placement table. Under the action of the gravity of the cup body assembly 110 itself, the push rod 33 is subjected to the reaction force of the placement table, and the push rod 33 is pressed into the cup body assembly 110 and retracted. Then, the push rod 33 pushes the external magnetic part to move and away from the internal magnetic part 23. Since the distance between the external magnetic part and the internal magnetic part 23 is too large, the magnetic attraction between the two is rapidly weakened. At this time, when the user operates the crushing device 2, the magnetic attraction of the external magnetic part to the crushing device is in a negligible state. It should be noted that although the distance between the outer magnetic part and the inner magnetic part becomes larger, the magnetic attraction of the outer magnetic part to the inner magnetic part has not been completely eliminated. However, for the user, when operating the crushing device, the crushing device itself has weight, and there will be friction between the crushing device and the inner wall of the cup body assembly. The combined force of the crushing device's own gravity, friction, and the magnetic attraction of the external magnetic part to the crushing device needs to be overcome by the user. When the magnetic attraction between the outer magnetic part and the inner magnetic part is sufficiently small relative to the gravity of the crushing device, it is an acceptable operating force for the user. Therefore, the present application does not necessarily have to reduce the magnetic attraction between the outer magnetic part and the inner magnetic part to completely disappear or be small enough, but it is sufficient to reach a range that the user can bear.

[0067] The locking device and internal magnetic member enable the crushing device to be securely fixed to the inner bottom of the cup assembly under normal conditions, enabling normal operation of the crushing device. When the crushing device needs to be removed, the user does not need to additionally operate the cup assembly while operating the crushing device. Therefore, the cup assembly normally placed on the work surface can unlock the crushing device under the action of its own weight, allowing the user to conveniently remove the crushing device. The locking device and internal magnetic member are provided to perform different functions at different operating times to meet different needs. This allows the locking device to provide a sufficiently large magnetic attraction to ensure the stability and security of the crushing device, while also achieving a weakened magnetic attraction to facilitate the user's direct removal of the crushing device. In particular, the locking device's operating state switching does not require excessive user involvement and can be achieved by simply placing the cup assembly naturally. This ultimately provides the user with a food processor that is safe and secure during operation and easy to operate during use.

[0068] As a specific embodiment of the food processing machine which is easy to operate according to the present invention, Figure 1-7As 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 therein. The motor shaft of the motor 101 extends into the housing, and an active magnetic 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 fixed to the upper end of the base 100 by the mounting platform. The cup assembly 110 includes a cup 120, a blade disc 122, a crushing device 2, and a locking device 3. The cup 120 preferably includes a body 121 and a blade disc 122. The body 121 is cylindrical and made of glass, with upper and lower openings. The blade disc 122 is preferably made of stainless steel and closes the lower opening of the body 121. The body 121 and the blade disc 122 form a complete cup 120, and the interior of the cup 120 forms a processing chamber.

[0069] 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. 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. The shell 24 is provided with an opening, and a bottom cover 241 that closes the shell 24 is provided at the opening. The shell 24 and the bottom cover 241 are used to form a closed cavity inside the crushing device 2, 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 they are in direct contact with liquid. The driven disk assembly 22 includes a driven disk body 221, a knife shaft 222, a bearing 223 and a shaft seal 224. The driven disk body 221 is fixedly connected to the knife shaft 222. Preferably, the driven disk body 221 is provided with a permanent magnet to magnetically cooperate with the active disk assembly 102. The bearing 223 is sleeved on the outside of the knife shaft 222 and installed in the shell 24. The knife shaft 222 passes through the shell 24 to be fixedly connected to the crushing element 21. The shaft seal 224 is provided at the opening of the shell 24 for the knife shaft 222 to pass through. An inner accommodating chamber 25 is formed inside the shell 24, and the inner magnetic part 23 is arranged in the inner accommodating chamber 25. Preferably, the inner magnetic part 23 is annular and surrounds the outer circumference of the driven magnetic disk body 221. In the axial direction, the inner magnetic part 23 and the driven magnetic disk body 221 are both close to the bottom cover 241. Since the driven magnetic disk assembly 221 needs to rotate, a certain gap is required between it and the bottom cover 241, and the inner magnetic part 23 does not need to rotate and can be directly fitted with the bottom cover 241. This can reduce the distance between the inner magnetic part and the driven magnetic disk assembly and the outer magnetic part and the active magnetic disk assembly, thereby enhancing the magnetic attraction between them.

[0070] Preferably, the cup body assembly 110 is further provided with a cup body shell and a cup body bracket 4 on the outside of the cup body 120, and an installation space for installing the locking device 3 is formed between the cup body shell, the cup body 120 and the cup body bracket 4. The locking device 3 includes an external magnetic part and a top rod 34, wherein the external magnetic part includes an external magnet 31 and a mounting bracket 32 ​​for mounting the external magnet 31. A transmission cavity 41 is also provided at the bottom of the cup body bracket 4. When the cup body assembly 110 is installed on the machine base 100, the active disk assembly 102 is inserted into the transmission cavity 41 to be close to the bottom wall of the cup body 120, so that the active disk assembly 102 can be close to the driven disk assembly 22 to realize power transmission. The mounting bracket 32 ​​is sleeved on the outer periphery of the transmission cavity 41. When the active disk assembly 102 is inserted into the mounting cavity 41, the external magnetic part surrounds the outer periphery of the active disk assembly 102. Preferably, the external magnetic parts are provided in two groups, a single mounting bracket is fan-shaped, and the two mounting brackets are provided around the center of the pulverizing device so that the two external magnetic parts are opposite to the internal magnetic parts in the pulverizing device. The internal magnetic part 23 is annular and is provided opposite to the two groups of external magnetic parts, and a plurality of groups of permanent magnets are provided in the internal magnetic part 23, which are magnetically attracted to the permanent magnets provided in the external magnetic parts, and the magnetic poles of the permanent magnets of the internal magnetic part and the external magnetic part are provided opposite to each other in the axial direction. With such a setting, on the premise that the active disk assembly is sufficiently close to the driven disk assembly, the active disk assembly and the driven disk assembly, the internal magnetic part and the external magnetic part are all better aligned, ensuring that they have the maximum magnetic attraction when they are installed in place. The magnetic poles of the permanent magnet are arranged along the axial direction. When the inner magnetic part and the outer magnetic part overlap in the axial direction, they can have the maximum magnetic attraction to ensure that the crushing device is securely installed; and when the inner magnetic part and the outer magnetic part are misaligned, the magnetic attraction between the inner magnetic part and the outer magnetic part can be quickly weakened, making it easier to remove the crushing device.

[0071] A limiting hole 42 is also provided at the bottom of the cup body bracket 4, and the push rod 34 includes an extension section 333 located in the limiting hole 42 and a limiting section 332 located in the upper section of the limiting hole 42. Preferably, the limiting hole 42 and the extension section 333 are both set to be cylindrical, so that the extension section 333 can easily slide in the limiting hole 42, and the limiting section 332 is set to be square or polygonal, and cooperates with the cup body bracket 4, so that the limiting section 332 can limit the push rod 34 in the circumferential direction, so that the push rod 34 can better push the external magnetic part away from the internal magnetic part. The push rod 34 passes through the limiting hole 42 and protrudes from the bottom end of the cup body assembly 110, so that when the cup body assembly 110 is normally placed on a horizontal table, the push rod 34 can serve as the main support between the table. Therefore, under the action of the gravity of the cup body assembly 110 itself, the table can exert a reaction force on the push rod 34, causing the push rod 34 to move axially along the limiting hole 42 and be compressed and contracted into the cup body assembly 110.

[0072] like Figure 4-Figure 6 As shown, the locking device 3 further includes a connecting rod 34, which is located between the push rod 33 and the mounting bracket 32. A pushing sliding surface is provided between the push rod 33 and the connecting rod 34, and between the connecting rod 34 and the mounting bracket 32. The top end of the push rod 33 is provided with a first pushing surface 331, and one end of the connecting rod 34 is provided with a first sliding surface 341. The first pushing surface 331 and the first sliding surface 341 are matching inclined surfaces. When the push rod 33 moves upward, the first pushing surface 331 and the first sliding surface 341 push the connecting rod 34 to move to one side. Furthermore, the other end of the connecting rod 34 is provided with a connecting rod pushing portion 343, and the side of the connecting rod pushing portion 343 is provided with a second pushing surface 344. The mounting bracket 32 ​​has a bracket body 321, and a second sliding surface 322 is formed at a relative position between the bracket body 321 and the second pushing surface 344. When the connecting rod 34 is pushed by the top rod 33 to move radially, the second pushing surface 344 and the second sliding surface 322 cooperate, so that the connecting rod 34 further pushes the mounting bracket 32 ​​to move radially, and drives the outer magnet 31 to move radially, so that the outer magnet 31 and the inner magnetic part 23 are misaligned and distanced from each other, thereby weakening the magnetic attraction between the outer magnet 31 and the inner magnetic part 23, so that the crushing device 2 can be easily taken.

[0073] Sliding structures are provided between the cup body bracket 4 and the mounting bracket 32, and between the cup body bracket 4 and the connecting rod 34. Preferably, guide rails and slides are provided radially between the cup body bracket 4 and the mounting bracket 32 ​​and the connecting rod 34. A bracket guide portion 323 extends outward from the outer side of the bracket main body 321 of the mounting bracket 32, and the bracket guide portion 323 is provided with a bracket guide groove 324 forming a guide rail. The cup body bracket 4 is provided with a bracket mounting platform 433, and a bracket guide column 432 is provided on the bracket mounting platform 433, which is inserted into the bracket guide groove 324 and forms a slider. When the mounting bracket 32 ​​is subjected to a pushing force, the mounting bracket 32 ​​slides along the bracket guide groove 324 under the limiting action of the bracket guide column 432, so that the mounting bracket 32 ​​and the external magnet 31 are away from the internal magnetic part 23. Accordingly, the connecting rod 34 is provided with a connecting rod guide groove 342 forming a guide rail, and the cup body bracket 4 is provided with a connecting rod guide post 431 inserted into the connecting rod guide groove 342 to form a slider. When the connecting rod 34 is pushed and squeezed by the push rod 33, the connecting rod 34 slides along the connecting rod guide groove 342 under the restraining action of the connecting rod guide post 431, thereby transmitting the pushing force of the push rod 33 to the mounting bracket 32.

[0074] The locking device 3 is also provided with an elastic member that pushes the external magnetic member to reset. Preferably, the elastic member is a spring 35 provided between the cup body bracket 4 and the mounting bracket 32. The spring 35 pushes against the mounting bracket 32. When the external force acting on the mounting bracket 32 ​​is eliminated, the spring 35 pushes the mounting bracket 32 ​​back to a position aligned with the internal magnetic member 23, so as to ensure that when the crushing device 2 is installed in place, the locking device 3 can promptly lock the crushing device 2. Preferably, the locking device 3 is also provided with springs that respectively push the top rod 33 and the connecting rod 34 to reset. When the cup body assembly is picked up, the top rod 33, the connecting rod 34 and the external magnetic member can all be promptly reset.

[0075] like Figure 4As shown, the housing 103 is further provided with an escape hole 104. When the cup assembly 110 is mounted on the base 100, the push rod 33 is located in the escape hole 104 and does not directly abut against the base 100. As a result, the base 100 does not exert a reaction force on the push rod. When the cup assembly 110 is normally placed on the base 100, the locking device 3 can still lock the pulverizing device. Such an arrangement can ensure that the pulverizing device 2 is in the proper installation position except when it needs to be disassembled, thereby ensuring that the driven disk assembly and the active disk assembly can be accurately aligned. In addition, it can also prevent the ejector 33 from being unstable in the installation between the cup body assembly 110 and the machine base 100 when it is subjected to the reaction force of the machine base 100, thereby affecting the precise alignment of the cup body assembly. Furthermore, the locking device 3 can continuously lock the pulverizing device during operation. Even if the magnetic poles of the active disk assembly and the driven disk assembly are misaligned due to knife jamming or other conditions during operation, and a reverse force is generated, the locking device can ensure that the pulverizing device is in a reliable position to prevent the pulverizing device from shifting during operation and affecting the normal operation of the food processor.

[0076] The exposed length of the push rod protruding from the lower end surface of the cup body assembly depends on the structural settings of the push rod, connecting rod and external magnetic part. Generally speaking, in order not to affect the overall structure and appearance of the cup body assembly, the length of the push rod protruding from the lower end surface is not more than 10 mm. The mutual cooperation between the connecting rod and the external magnetic part is utilized to achieve the required displacement of the external magnetic part, and finally ensure that the magnetic attraction between the external magnetic part and the internal magnetic part does not affect the user's operation.

[0077] By providing a locking device, the external magnetic element of the locking device can stably attach the pulverizing device to the cup assembly when it is needed. When the user needs to remove the pulverizing device, they simply place the cup assembly normally on the workbench, and the cup assembly itself can be used to unlock the locking device, requiring no additional action, making operation simple and convenient. Furthermore, by providing elastic members and avoidance holes in the base, the locking device is prevented from interfering with the cup assembly or base during normal operation of the food processor. Because the pulverizing device is operated at different stages, the locking device can be used to apply different forces to the pulverizing device at different stages. This achieves the goal of applying a sufficiently secure locking force to the pulverizing device while also weakening the force applied to the pulverizing device, allowing the user to conveniently operate 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 convenient 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.

[0078] It is understood that the external magnetic member can also move axially under the push of the push rod. For example, a support rod is provided at the bottom of the cup assembly, and the support rod is respectively linked to the push rod and the external magnetic member. The push rod moves upward under the extrusion force and pushes the support rod. The support rod rotates about the central rotation fulcrum and drives the external magnetic member to move axially downward, thereby increasing the distance between the external magnetic member and the inner magnetic member.

[0079] It is understandable that the external magnetic member can also be arranged to rotate along the circumference of the cup body assembly. For example, the external magnetic member and the internal magnetic member are provided with multiple sets of permanent magnets, or the crushing device and the cup body assembly have a specific installation direction, so that the external magnetic member and the internal magnetic member can have magnetic poles that attract each other. When the external magnetic member is pushed by the top rod, it rotates along the circumference of the cup body assembly, so that the magnetic pole directions of the external magnetic member and the inner magnetic member are misaligned or repelled, thereby facilitating the removal of the crushing device.

[0080] It is understandable that the external magnetic part can also be arranged to rotate radially along the cup body assembly. For example, the magnetic poles of the permanent magnets of the external magnetic part and the internal magnetic part are both arranged axially, and the external magnetic part is pushed by the top rod to rotate radially along the cup body assembly, so that the magnetic poles of the permanent magnets of the external magnetic part and the internal magnetic part are misaligned or the magnetic poles repel each other. For example, when the external magnetic part rotates 90 degrees, the magnetic poles of the permanent magnets of the external magnetic part and the internal magnetic part are misaligned by 90 degrees, and the magnetic attraction between the external magnetic part and the internal magnetic part is eliminated; or, the external magnetic part rotates 180 degrees, so that the magnetic poles of the external magnetic part are reversed. At this time, the magnetic attraction of the external magnetic part and the internal magnetic part changes from attraction to repulsion. The external magnetic part can push the internal magnetic part and drive the crushing device out of its original position, making it more convenient for users to pick up the crushing device.

[0081] It is understandable that the outer magnetic member may also be directly formed by an annular permanent magnet without providing a mounting bracket for mounting the permanent magnet.

[0082] It is understood that the inner magnetic member and the driven magnetic member can be positioned at different locations based on the shape variations of the active magnetic member and the driven magnetic member. For example, a sink is provided at the bottom of the cup body to accommodate the pulverizing device, the outer magnetic member is disposed on the periphery of the sink, and the inner magnetic member is disposed at an axial height corresponding to the outer magnetic member, for example, above the driven magnetic member.

[0083] 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.

[0084] As another preferred embodiment of the food processor that is easy to operate as described in this application, Figure 8-Figure 1 As shown in FIG4 , the locking device includes an external magnetic member and a push rod, wherein the push rod protrudes downward from the lower end surface of the cup body assembly, and the push rod directly abuts against the external magnetic member upward to push the external magnetic member to move.

[0085] like Figure 8 、 Figure 9As shown, the food processor includes a cup assembly, which is equipped with a detachable crushing device 2. The crushing device 2 includes a crushing element 21, a driven magnetic disk assembly 22, and an internal magnetic element 23. The cup assembly is also equipped with a locking device located outside the cup body. The locking device includes an external magnetic element and a push rod 33. The external magnetic element includes an external magnet and a mounting bracket 32. The external magnet is a plurality of permanent magnets assembled on the mounting bracket 32. The push rod 33 includes an extension section at the bottom and a push section 334 at the top. The extension section protrudes downward from the lower end surface of the cup assembly. The push sections 334 are symmetrically arranged, with extension structures on both sides. First push surfaces 331 are formed on both sides of the push section 334.

[0086] like Figure 10-13 As shown, the mounting bracket 32 ​​completely wraps the external magnet to prevent the permanent magnet constituting the external magnet from leaking out and rusting or corroding, so as to ensure that the external magnet can work stably and reliably. The external magnetic parts are arranged in two symmetrical groups, each of the mounting brackets 32 is fan-shaped, the mounting bracket 32 ​​is provided with a bracket guide groove 324, and the cup body bracket 4 is provided with a bracket guide column 432. When the mounting bracket 32 ​​is installed on the cup body bracket 4, the bracket guide column 432 is inserted into the bracket guide groove 324. Furthermore, the end of the bracket guide column 432 is fixed with a limit screw 434. The limit screw 434 is used to limit the axial movement of the mounting bracket 32, and the bracket guide groove 324 and the bracket guide column 432 limit the mounting bracket 32 ​​to be easily movable along the radial direction of the bracket guide groove 324. The cup body bracket 4 is further provided with a bracket mounting platform 433 , a mounting groove is formed in the bracket mounting platform 433 , a spring 35 is provided in the mounting groove, one end of the spring 35 abuts against the bracket mounting platform 433 , and the other end abuts against the mounting bracket 32 ​​.

[0087] like Figure 14A 、 Figure 14B As shown, Figure 14A Indicates the position of the locking device when the push rod 33 is not subjected to external force; Figure 14B Indicates the position of the locking device when the push rod 33 is subjected to external extrusion force. Figure 14AAs shown, when the cup assembly is operated by the user, or placed on the machine base and is not subjected to external pressure, the push rod 33 protrudes outward from the lower end surface of the cup assembly, and the external magnetic part is not pushed by the push rod 33. The mounting bracket 32 ​​is pushed by the spring 35 and is located near the center of the cup assembly. At this time, the external magnetic part is magnetically engaged with the internal magnetic part of the crushing device placed in the cup body to lock the crushing device inside the cup body, thereby preventing the crushing device from falling off when the user operates the cup assembly as a whole. Figure 14B As shown, when the cup assembly is in a non-operating, freely placed position, such as when the cup assembly is freely placed on a kitchen countertop, the downwardly protruding push rod 33 contacts the countertop and, under the weight of the cup assembly, is subjected to a reverse force. The push rod 33 is pressed downward, moving axially along the cup assembly, pushing and squeezing the mounting bracket 32 ​​upward. The first pushing surface 331 and the second sliding surface 322 cooperate with each other to decompose the axial force of the push rod 33 into a radial force, pushing the mounting bracket 32 ​​to slide along the extension direction of the bracket guide slot 324, thereby driving the permanent magnet disposed within the mounting bracket 32 ​​away from its original locked position. At this point, the outer magnetic member and the inner magnetic member are misaligned, and the magnetic attraction of the outer magnetic member to the inner magnetic member rapidly weakens, eliminating the locking effect of the outer magnetic member on the pulverizing device, allowing the user to easily remove the pulverizing device from the cup assembly. When the cup assembly is removed again, the spring 35 pushes the mounting bracket 32, driving the outer magnet back to its locked position against the pulverizing device.

[0088] Depending on the structure of the cup assembly, the push rod is directly provided to push the external magnetic member, rather than a connecting rod. This can improve the efficiency of the push rod's force transmission to the external magnetic member, ensuring that the external magnetic member switches between the locked and unlocked positions more quickly and effectively. The mounting bracket and external magnets are arranged in two symmetrical groups, which can more evenly lock the crushing device within the cup. The two groups of external magnetic members can move outward separately, allowing for easier disengagement from the internal magnetic member. Typically, a coupler assembly is electrically connected between the cup assembly and the base, and a stopper structure is provided between the cup assembly and the base to maintain alignment between the active and passive magnetic disk assemblies. Preferably, in this embodiment, the push rod is positioned between the upper coupler and the passive magnetic disk assembly of the cup assembly, and is located on the side of the cup assembly's handle. In this manner, when the user places the cup assembly, the side of the cup assembly away from the handle and push rod first contacts the countertop, ensuring the stability of the cup assembly. As the cup assembly gradually lies horizontally, the push rod is then pressed against the countertop, unlocking the crushing device. When the cup body assembly is picked up, the bottom of the cup on the handle side is first separated from the table, so that the squeezing force on the top rod disappears, and then drives the external magnetic part to quickly lock the crushing device. That is, usually after the cup body assembly is separated from the table, the crushing device has been locked, making the food processor safer and more reliable.

[0089] It is understandable that the push rod can also be set at other different positions according to the bottom space structure of the cup body assembly. It only needs to ensure that the push rod can push the external magnetic part away from the locking position when the cup body assembly is placed on the table.

[0090] As can be understood, due to the strong magnetic attraction between the active and passive magnetic disk assemblies, when the cup assembly is placed on the base, the pulverizing device will not move out of its installed position, even if the external magnetic member does not lock it. Therefore, the base does not need to have a clearance hole for the ejector pin. When the cup assembly is placed on the base, the ejector pin abuts against the base and unlocks the pulverizing device.

[0091] It can be understood that a safety switch assembly can be further provided on the machine base corresponding to the push rod. When the cup body assembly is installed on the machine base, the push rod triggers the safety switch assembly downward, thereby improving the safety of the food processor. The safety switch assembly can also be used to identify and determine whether the crushing device is installed in place, thereby improving the working reliability of the food processor.

[0092] As another preferred embodiment of the food processor that is easy to operate as described in this application, Figure 15As shown, the locking device includes two push rods and two sets of external magnetic parts. The two push rods simultaneously protrude downward from the lower end surface of the cup body assembly and push the external magnetic parts to move when subjected to extrusion force.

[0093] like Figure 15 As shown, the locking device comprises two sets of symmetrically arranged external magnetic members, each comprising a mounting bracket 32 ​​and an external magnet embedded within the mounting bracket 32. The locking device also comprises two symmetrically arranged push rods 33, one at each end of the mounting bracket 32. The bottom ends of the two push rods 33 simultaneously protrude downward from the lower end surface of the cup assembly. When the cup assembly is placed on a table, the two push rods 33 simultaneously contract inward due to the reaction force, pushing the mounting bracket 32, thereby moving the external magnet and ultimately unlocking the pulverizing device.

[0094] Two push rods are provided to ensure that when the cup assembly is placed on the table, the push rods can push the external magnetic member out of the locked position. In addition, the two symmetrically arranged push rods also ensure more uniform force distribution, preventing excessive force on a single push rod from lifting the cup assembly and affecting its normal horizontal placement.

[0095] It is understandable that the push rod and the external magnetic member can be independently provided as a set and provided in multiple groups. When the cup assembly is placed on the table, each push rod pushes the corresponding external magnetic member out of the locked position.

[0096] It can be understood that the push rod is annular and is arranged at the bottom of the cup body assembly. The annular push rod is sleeved on the outside of the transmission cavity of the bottom of the cup body for accommodating the active disk assembly. The annular push rod protrudes downward from the cup body assembly, and the upper end of the push rod abuts against the external magnetic part. When the cup body assembly is placed on the table, the annular push rod contacts the table and is squeezed to push the external magnetic part to move and unlock the crushing device.

[0097] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes and modifications made based on the present invention are covered by the scope of the claims of the present invention and will not be listed one by one here.
