Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, and more specifically to a multifunctional food processing machine. Background Technology

[0002] In recent years, as consumers have increasingly pursued higher quality of life and healthier food, more and more people enjoy making healthy meals at home. For example, when making minced meat dishes, people used to either have it ground at a commercial meat grinder at the market or buy it and chop it themselves at home. However, the former often resulted in unsanitary conditions, as vendors didn't properly clean the machines or the meat, leading to potential hygiene issues with the minced meat. The latter required more manpower and time. Therefore, the emergence of household electric meat grinders has solved these problems, entering countless households and becoming a popular kitchen appliance for many families.

[0003] However, the meat grinding bowls used in existing household meat grinders are suitable for grinding large quantities of meat and vegetables. When using traditional meat grinding bowls to prepare small amounts of complementary food, the ingredients for the complementary food are often only spread on the bottom of the meat grinding bowl, or even below the bottom blades, resulting in poor results in making complementary food.

[0004] To address this, patent application CN202220362985.2 discloses a meat grinder cup and a multi-functional meat grinder, comprising: a housing, a lid, a grinding bowl, a drive unit, a blade holder, and a cup. The drive unit is located inside the housing, with the lower end of the housing inserted into a groove on the lid. The lid is positioned on top of the grinding bowl. The cup has an open structure at both ends, with internal partitions. The top surface of the partition forms grinding chambers with the upper end of the cup, and the bottom surface forms grinding chambers with the lower end of the cup. The cup is placed inside the grinding bowl, with its top contacting the lid. This patent design features a cup smaller than the grinding bowl, facilitating the grinding of small quantities of baby food ingredients. When grinding large quantities of meat products, the cup is removed, and the meat is ground through the grinding bowl, fulfilling multi-functional grinding needs. It offers good grinding effect, wide applicability, and convenient operation. The two grinding chambers of the meat grinder cup can be used interchangeably, preventing flavor mixing.

[0005] However, this approach has the following problems:

[0006] 1. Because the meat grinder cup is a two-way cup placed on the inner bottom surface of the meat grinder bowl, and the upper part of the cup only contacts or maintains a small gap with the annular flange at the bottom of the lid, the vibration caused by the stirring of ingredients and the linkage of the main unit during the preparation of complementary food will cause the meat grinder cup to move relative to the meat grinder bowl and produce abnormal noise, and even the complementary food knife will be misaligned relative to the output shaft hole of the main unit, resulting in the phenomenon of knife jamming.

[0007] 2. When the ingredients are prepared and the main unit is removed immediately, there is a possibility that the lid will be taken away, leaving the baby food knife exposed. The baby food knife may still be rotating due to inertia when the main unit is removed immediately, which poses a safety issue.

[0008] 3. This type of two-way cup consists of a first cup and a second cup with openings facing opposite directions. After food is prepared in the first cup, if the two-way cup is inverted for use, any remaining baby food (usually pumpkin puree, yam puree, or other slightly liquid foods easy for babies to eat) will flow down the cup wall into the meat grinder bowl, contaminating it and increasing cleaning difficulty. To solve this problem, the two-way cup must be thoroughly cleaned after each use, adding to the complexity of food preparation.

[0009] 4. The two-way cup occupies the entire axial space of the meat grinder bowl, making it impossible to add other cups. This limits the meat grinder bowl to only accommodating one two-way cup and prevents the addition of more functional cups. Summary of the Invention

[0010] The purpose of this invention is to provide a multifunctional food processing machine that, while meeting the needs of producing meat grinders and complementary foods in different capacities, solves the problem of excessive noise from complementary food cups in the prior art.

[0011] To achieve the above objectives, the present invention provides a multifunctional food processing machine, characterized in that it comprises: a first cup body; a second cup body, the second cup body being housed within the first cup body; a cup lid, the cup lid covering the first cup body; a main unit, the main unit containing a motor, the main unit being mounted on the cup lid; a first pulverizing blade, the first pulverizing blade being disposed within the first cup body, the top of the blade shaft of the first pulverizing blade being connected to the motor for transmission; a second pulverizing blade, the second pulverizing blade being disposed within the second cup body, the blade shaft height of the first pulverizing blade being greater than the blade shaft height of the second pulverizing blade; the cup lid includes a first mounting portion and a second mounting portion disposed inside the first mounting portion, the first cup body being in a limiting fit with the first mounting portion, and the second cup body being detachably connected to the second mounting portion; the second cup body is suspended below the cup lid, and the outer bottom surface of the second cup body is suspended relative to the inner bottom surface of the first cup body to form a U-shaped noise reduction cavity between the second cup body and the first cup body, the plumb projection of the second cup body falling within the plumb projection range of the rotation space formed by the rotation of the first pulverizing blade.

[0012] This invention provides a multifunctional food processor that, by incorporating a first cup and a second cup, allows for the separate processing of meat, vegetables, and baby food, preventing flavor contamination within a single cup. The second cup is housed within the first cup, solving the storage problem for multiple cups. Furthermore, by setting different blade shaft heights for the first and second pulverizing blades, the two different blades can be adapted to cups of different capacities, improving the compatibility of the blades with different cups and enhancing the pulverizing effect. In this food processor, by providing a first mounting part on the cup lid and a second mounting part located inside the first mounting part, with the first cup and the first mounting part in a limiting fit, and the second cup and the second mounting part being detachably connected, a single cup lid can accommodate multiple cups. Compared to existing technologies where large cups are fitted with large lids and small cups with small lids, this eliminates the need for a separate cup lid, resulting in lower costs. The second cup is suspended below the lid, with its outer bottom surface suspended relative to the inner bottom surface of the first cup. This design serves several purposes: first, it prevents contact between the outer bottom surface of the second cup and the inner bottom surface of the first cup, thus avoiding friction and noise during operation; second, it creates a U-shaped noise reduction cavity between the two cups, attenuating the noise generated by the second pulverizing blade pulverizing the food before it reaches the first cup, thereby reducing noise and improving the user experience; and third, the suspension of the second cup increases the weight of the lid, effectively preventing the lid from being accidentally pulled off the first cup when the user removes the main unit, thus mitigating the installation risk caused by the exposed and still rotating second pulverizing blade. To further reduce noise during operation, the design ensures that the plumb bob projection of the second cup falls within the plumb bob projection range of the rotational space formed by the first pulverizing blade, meaning the bottom area of ​​the second cup is smaller than the outer perimeter area of ​​the rotational space of the first pulverizing blade. Normally, the first crushing blade must be in clearance fit with the inner sidewall of the first cup. However, in this solution, by setting the projection of the plumb bob of the second cup to fall within the projection range of the plumb bob in the rotational space formed by the rotation of the first crushing blade, the lateral width of the noise reduction cavity between the sidewall of the second cup and the sidewall of the first cup is widened, thereby increasing the volume of the U-shaped noise reduction cavity. That is, the lateral width is wider than the gap between the first crushing blade and the inner sidewall of the first cup, thereby reducing the working noise generated by the second cup in the working state.

[0013] Preferably, the first mounting portion includes a first surrounding wall for extending into the first cup body and radially limiting the first cup body, the cup lid includes a cavity for accommodating the main unit, the outer wall of the cavity is clearance-fitted with the first surrounding wall, and the second mounting portion is disposed on the outer wall of the cavity.

[0014] By setting the first mounting part as a first enclosure wall that radially limits the first cup body, radial limiting of the cup lid and the first cup body is achieved, preventing the cup lid from radially detaching from the first cup body during operation and thus avoiding food splashing. Simultaneously, by setting a cavity to accommodate the main unit, both radial limiting of the main unit and lowering its center of gravity are achieved, thereby improving the working stability of the food processor. Furthermore, by setting a gap fit between the outer wall of the cavity and the first enclosure wall, the second mounting part is placed on the outer wall of the cavity. This allows the noise generated by the main unit to pass through the gap before being transmitted to the outside, providing a certain degree of noise reduction. Moreover, the second mounting part is directly mounted on the outer wall of the cavity, eliminating the cost of separately setting a second mounting part on the cup lid to install the second cup body; the main unit is installed inside the cavity, and the second cup body is installed outside, serving a dual purpose. In addition, the radial limiting of the second cup body by the outer wall of the cavity prevents radial displacement of the second cup body, improving the coaxiality of the second cup body, the second pulverizing blade, and the through hole of the cup lid, effectively preventing blade jamming.

[0015] Preferably, the outer wall of the cavity includes an outer bottom wall and an outer side wall. The outer bottom wall is not higher than the top wall of the first cup body. A second surrounding wall extending downward is provided on the outer bottom wall, and the second mounting part is located on the second surrounding wall.

[0016] To further reduce the height of the main unit and improve the stability of the food processor during operation, the outer bottom wall of the concave cavity is designed to be no higher than the top wall of the first cup body. Furthermore, by providing an extended second enclosure wall on the outer bottom wall of the concave cavity, with the second mounting portion located on the second enclosure wall, the center of gravity of the second cup body is lowered. This, in turn, lowers the overall center of gravity of the main unit, the lid, and the second cup body, resulting in a more stable fit between the lid and the first cup body. Consequently, the food processor operates more smoothly when using the second cup body to prepare food.

[0017] Preferably, the second mounting part includes a screw-in groove provided on the inner side of the second enclosure and a screw-in rib provided on the outer side of the second cup body that protrudes radially outward, and the second enclosure extends into the U-shaped noise reduction cavity.

[0018] The engagement groove and engagement ribs ensure a stable fit between the second cup body and the lid, while the engagement structure is simple and easy to install. Furthermore, the engagement groove is located inside the second enclosure, allowing for lateral shielding of any small amount of food splashing from the second cup body, preventing it from splashing into the first cup body. Generally, for ease of installation, the second cup body and lid are loosely fitted. Therefore, the second enclosure extending into the U-shaped noise reduction cavity not only lowers the working center of gravity of the second cup body but also effectively blocks noise generated by the collision between the second cup body and the second enclosure.

[0019] Preferably, the inner bottom surface of the first cup body is provided with a first positioning post that cooperates with the first crushing blade, the inner bottom surface of the second cup body is provided with a second positioning post that cooperates with the second crushing blade, a first radial swing gap L1 is provided between the first crushing blade and the through hole of the cup lid, a second radial swing gap L2 is provided between the second crushing blade and the through hole of the cup lid, and the lateral offset difference between the central axis of the first positioning post and the central axis of the second positioning post is L3, wherein the smaller of L1 and L2 is greater than or equal to L3.

[0020] To improve the working stability of the first pulverizing blade, a first positioning post that mates with the first pulverizing blade is provided on the inner bottom surface of the first cup body; to improve the working stability of the second pulverizing blade, a second positioning post that mates with the second pulverizing blade is provided inside the second cup body. In the food processing machine provided by this invention, the through hole of a single cup lid needs to accommodate two different pulverizing blades. To ensure that the blade shafts of both the first and second pulverizing blades can pass through the through hole of the cup lid and connect to the motor of the main unit, a first radial swing gap L1 is provided between the first pulverizing blade and the through hole of the cup lid, and a second radial swing gap L2 is provided between the second pulverizing blade and the through hole of the cup lid. However, due to manufacturing and installation tolerances in the positions of the second and first positioning posts in the second cup body, and because the fit between the second cup body and the cup lid is loose, the positioning shaft of the second cup body and the through hole of the cup lid are not located on the same axis, nor are the positioning shaft of the first cup body and the through hole of the cup lid. Therefore, to compensate for the manufacturing and installation tolerances of the two positioning posts and the deviation in the fit of the cup lid of the second cup body, and to ensure that both the second and first pulverizing blades can smoothly pass through the through holes of the cup lid and connect to the main drive, a lateral offset difference of L3 is set between the central axes of the first and second positioning posts, where the smaller of L1 and L2 is greater than or equal to L3. If L2 is less than L1 and L2 is less than L3, the second pulverizing blade will not be able to pass through the through holes of the cup lid and connect to the main drive; if L1 is less than L2 and L1 is less than L3, the first pulverizing blade will not be able to pass through the through holes of the cup lid and connect to the main drive; if L1 is equal to L2 and both L1 and L2 are less than L3, neither the first nor the second pulverizing blade will be able to pass through the through holes of the cup lid and connect to the main drive.

[0021] Preferably, the bottom wall of the second cup body is located below half the height of the first cup body; or, the top surface of the second cup body is lower than the top surface of the first cup body.

[0022] The bottom wall of the second cup is located below half the height of the first cup, thereby lowering the center of gravity of the entire assembly of the first and second cups, along with the lid and main unit. The top surface of the second cup is lower than the top surface of the first cup, which helps to lower the center of gravity of the first cup, lid, and main unit after assembly. This lowers the center of gravity of the entire machine, preventing the assembly from tilting or tipping over during operation or transportation, and improving the working stability of the food processing machine.

[0023] Preferably, the second shredder includes a shroud, a blade disposed on the shroud, and a baffle fixed to the outer periphery of the shroud. The baffle has a blunt end at the front end of the shroud in the rotation direction and extends obliquely upward along the rotation direction of the shroud. The blade includes a first blade located below the baffle and the first blade has a cutting edge at the front end of the shroud in the rotation direction.

[0024] The second pulverizer provided by this invention also includes a baffle plate. The baffle plate has a blunt end and extends obliquely upward along the rotation direction of the pulverizer shaft. During the rotation of the pulverizer shaft, the material located in front of the baffle plate is pushed forward and downward by the combined action of the blunt end and the lower surface of the baffle plate, thereby preventing the material from remaining at a certain height and increasing the probability of the material colliding with the cutting edge of the first blade, thus effectively cutting the material. The material located behind the baffle plate falls as the pulverizer shaft rotates and collides with the first blade, thus being effectively cut. Therefore, under the agitation of the baffle plate, the material is cyclically cut by the first blade from top to bottom, and the baffle plate can also press down the material to prevent it from splashing upward onto the lid, thus fully agitating the material inside the cup and increasing the probability of contact between the food and the cutting edge of the first blade. During the rotation of the pulverizer shaft, the first blade cyclically cuts the material, improving the pulverizing effect.

[0025] Preferably, the sidewall thickness of the second cup body is lower than that of the sidewall thickness of the first cup body; and / or, both the first cup body and the second cup body are made of transparent material.

[0026] Since the volume of the second cup is smaller than that of the first cup, and the second cup also needs to be suspended on the lid, in order to prevent the second cup from being too heavy and bending the lid or breaking at the connection between the second cup and the lid, the side wall thickness of the second cup is set to be lower than that of the first cup.

[0027] Furthermore, to reduce operating noise, the second cup is usually housed within the first cup during operation. Therefore, in this design, to improve visibility of the second cup during operation and facilitate observation of the food preparation process within the second cup through the first cup, both the first and second cups are made of transparent material.

[0028] Preferably, it further includes a third cup body that is replaceable and detachably connected to the second mounting portion, the second cup body and the third cup body being separably fitted together to form an assembly, the assembly being housed in the first cup body, and a U-shaped noise reduction cavity being formed between the assembly and the first cup body.

[0029] The food processor provided by this invention includes a second cup and a third cup housed within a first cup. The second and third cups are replaceably fixed to a second mounting part. The capacities of the second and third cups are smaller than those of the first cup, thus meeting users' needs for preparing ingredients of different capacities. For large-capacity ingredients, the larger first cup is used for processing; for small-capacity complementary foods, either the second or third cup is used, achieving multi-functionality and wide applicability. Furthermore, different cups can be used for different types of ingredients, thus solving the problem of flavor mixing. The second mounting part on the lid provides positioning for the second and third cups during processing, improving stability and preventing the lid from being removed along with the main unit after processing, avoiding inconvenience. It also prevents the pulverizing blades in the second or third cup from being exposed, thus improving safety. The second and third cups can be detachably fitted together to form a combined unit, allowing for convenient storage. Furthermore, the second and third cups can be used separately for easier independent cleaning. After using the second cup, the third cup can be used directly. This allows for cleaning of each cup only after preparing multiple types of ingredients, making cleaning more convenient. The combined unit is housed within the first cup, saving space and facilitating storage. It also prevents dust from accumulating on the second and third cups when not in use, ensuring easy access for future use.

[0030] Preferably, the food processor further includes a fourth cup body that is detachably mounted above the main unit, and the fourth cup body is provided with a fourth pulverizing blade.

[0031] By adding a fourth cup, the utilization rate of the main unit is further increased, the function of the food processor is expanded, and its application becomes more widespread. Attached Figure Description

[0051] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0052] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0053] like Figure 1-13 As shown, in one embodiment of the present invention, a multifunctional food processor is provided, including a main unit 1 with a motor 11 inside, which is mounted on a cup lid 25. The cup assembly 2 includes at least a first cup body 21 and a second cup body 22. The cup lid 25 covers the first cup body 21, and the second cup body 22 is housed within the first cup body 21. The cup lid 25 has a recess 252, in which the main unit 1 is housed. Simultaneously, by providing the recess 252 to house the main unit 1, the main unit 1 is radially limited, and its center of gravity is lowered, thereby improving the working stability of the food processor. In this solution, the first cup body 21 is used to prepare larger quantities of minced meat or chopped vegetables, while the second cup body 22 is used to prepare smaller quantities of complementary foods, such as pumpkin puree or yam puree for babies. By setting the first cup body 21 and the second cup body 22, meat, vegetables, and complementary foods can be processed separately, preventing cross-contamination of flavors within a single cup.

[0054] Specifically, the cup lid 25 includes a first mounting portion and a second mounting portion located inside the first mounting portion. When the first cup body 21 is in operation, it is in a limiting fit with the first mounting portion, and the second cup body 22 is located outside the first cup body 21. The pulverizing assembly 3 includes at least a first pulverizing blade 31 and a second pulverizing blade 32. The top of the blade shaft 35, which houses the first pulverizing blade 31, passes through the through hole 251 of the cup lid 25 and is connected to the motor 11 to drive the first pulverizing blade 31. When the second cup body 22 is in operation or stored, it is housed within the first cup body 21 and contains the second pulverizing blade 32. The first cup body 21 is in a limiting fit with the first mounting portion, and the second cup body 22 is detachably connected to the second mounting portion. The second cup body 22 is suspended below the cup lid 25, with its outer bottom surface suspended relative to the inner bottom surface of the first cup body 21 to form a U-shaped noise reduction cavity 4 between the second cup body 22 and the first cup body 21. The second cup 22 is placed inside the first cup 21, thus solving the problem of storing multiple cups.

[0055] By providing a first mounting part on the cup lid 25 and a second mounting part located inside the first mounting part, the first cup body 21 is limited and engaged with the first mounting part, and the second cup body 22 is detachably connected to the second mounting part, thus realizing the function of a single cup lid 25 adapting to multiple cup bodies. Compared with the existing technology where large cups are adapted to large cup lids 25 and small cups are adapted to small cup lids 25, a small cup lid 25 is eliminated, resulting in lower costs.

[0056] The second cup body 22 is suspended below the cup lid 25, with its outer bottom surface suspended relative to the inner bottom surface of the first cup body 21. This serves several purposes: first, it prevents contact between the outer bottom surface of the second cup body 22 and the inner bottom surface of the first cup body 21, thus avoiding noise caused by friction during operation; second, it creates a U-shaped noise reduction cavity 4 between the second cup body 22 and the first cup body 21, reducing the noise generated by the second pulverizing blade 32 pulverizing food before it reaches the outside of the first cup body 21, thereby achieving noise reduction and improving the user experience; third, the suspension of the second cup body 22 increases the weight of the cup lid 25, effectively preventing the cup lid 25 from being accidentally pulled off or taken away from the first cup body 21 when the user removes the main unit 1, thus mitigating the installation risk caused by the second pulverizing blade 32 being exposed and still rotating due to inertia in this situation.

[0057] It should also be noted that, in this design, since the second cup 22 needs to be housed within the first cup 21 and also needs to form a U-shaped noise reduction cavity 4, the blade shafts 35 of the first pulverizing blade 31 and the second pulverizing blade 32 need to be at different heights. The different heights of the blade shafts 35 allow the two different pulverizing blades to adapt to cups of different capacities, improving the compatibility of the pulverizing blades with different cups and enhancing the pulverizing effect.

[0058] Meanwhile, to further reduce noise during the operation of the second cup 22, this solution also sets the plumb projection of the second cup 22 to fall within the plumb projection range of the rotational space formed by the rotation of the first crushing blade 31. In other words, the bottom area of ​​the second cup 22 is smaller than the outer perimeter area of ​​the rotational space of the first crushing blade 31. Normally, the first crushing blade 31 necessarily has a clearance fit with the inner wall of the first cup 21. However, this solution increases the volume of the U-shaped noise reduction cavity 4 by setting the plumb projection of the second cup 22 to fall within the plumb projection range of the rotational space formed by the rotation of the first crushing blade 31. This means the lateral width of the noise reduction cavity 4 between the sidewall of the second cup 22 and the sidewall of the first cup 21 is wider than the gap between the first crushing blade 31 and the inner wall of the first cup 21, thereby reducing the operating noise generated by the second cup 22 during operation.

[0059] It is understandable that for some main unit 1s with relatively small size, that is, with relatively low height, the cavity 252 may not be set in the cup lid 25, but a flat adapter may be set for the main unit 1.

[0060] In some embodiments of the present invention, reference is made to Figure 2 The first mounting portion includes a first enclosure 26 for extending into the first cup body 21 and radially limiting its engagement with the first cup body 21. By setting the first mounting portion as the first enclosure 26 that radially limits its engagement with the first cup body 21, radial limiting of the cup lid 25 and the first cup body 21 is achieved, preventing the cup lid 25 from radially detaching from the first cup body 21 during operation, thus avoiding food splashing. To ensure the sealing between the cup lid 25 and the first enclosure 26, a sealing ring can also be fitted around the outer periphery of the first enclosure 26. The outer wall 2522 of the cavity 252 has a clearance fit with the first enclosure 26, so that when the noise generated by the main unit 1 is transmitted radially outward, it first passes through the aforementioned clearance before being transmitted to the outside, thus having a certain noise reduction effect on the main unit 1.

[0061] Regarding the specific structure of the second mounting part being located on the outer wall of the cavity 252, the present invention provides the following exemplary solutions:

[0062] The second mounting part is located on the outer wall of the cavity 252, eliminating the cost of separately setting a second mounting part on the cup lid 25 to install the second cup body 22. The main unit 1 is installed inside the cavity 252, and the second cup body 22 is installed outside, serving a dual purpose. The outer wall of the cavity 252 includes an outer bottom wall 2521 and an outer side wall 2522. In addition, the outer wall of the cavity 252 radially limits the second cup body 22, preventing radial displacement of the second cup body 22, improving the coaxiality of the second cup body 22, the second crushing blade 32, and the through hole 251 of the cup lid 25, and effectively avoiding blade jamming problems.

[0063] Example Solution 1: Figure 1-4 As shown, a downwardly extending second enclosure 2523 is provided on the outer bottom wall 2521, and the second mounting part is located on the second enclosure 2523. In this scheme, the second mounting part can be located on the inner side wall of the second enclosure 2523 or on the outer side wall 2522 of the second enclosure 2523, which is not specifically limited here. By providing a downwardly extending second enclosure 2523 on the outer bottom wall 2521 of the cavity 252, and with the second mounting part located on the second enclosure 2523, it is beneficial to lower the center of gravity of the second cup body 22, thereby lowering the overall center of gravity of the main unit 1, the cup lid 25, and the second cup body 22. This makes the fit between the cup lid 25 and the first cup body 21 more stable, and the overall food processor operates more smoothly when using the second cup body 22 to process food.

[0064] Exemplary Solution 2: Regardless of whether there is a downwardly extending second enclosure 2523 on the outer bottom wall 2521 of the cavity 252, the second mounting part is provided on the outer side wall 2522 of the cavity 252, that is, the cavity 252 partially extends into the second cup body 22. In this solution, if the second enclosure 2523 is provided, then the second enclosure 2523 extending into the second cup body 22 facilitates the shielding of food when it splashes upwards, causing the food to fall back and reducing the likelihood of food escaping through the gap between the second enclosure 2523 and the second cup body 22. Simultaneously, the second enclosure 2523 improves the radial limiting reliability of the second cup body 22. In this solution, if the second enclosure 2523 is not provided, the cost of providing the second enclosure 2523 can be saved, allowing the cavity 252 to serve both as a component housing the main unit 1 and as a component for mounting the second cup body 22.

[0065] Exemplary Solution 3: Reference Figure 13 The outer bottom wall 2521 of the cavity 252 first extends radially outward to a size greater than the outer diameter of the cavity 252, and then extends downward to form a second surrounding wall 2523, on which the second mounting part is located. In this scheme, compared with exemplary scheme 1, the second cup body 22 can be made with a relatively large capacity.

[0066] Specifically, the second mounting part may include a screw-in rib 2524 provided on the outer wall of the cavity 252 and a screw-in groove 2526 provided on the second cup body 22. Of course, the screw-in rib 2524 and the screw-in groove 2526 can also be replaced. Alternatively, a first thread may be provided on the outer wall of the cavity 252, and a second thread that meshes with the first thread may be provided on the second cup body 22. Further details will not be elaborated here.

[0067] In a preferred embodiment of the present invention, reference is made to... Figure 2 , 3The cup lid 25 also has a downwardly extending third enclosure 27 at the through hole 251. The interior of the third enclosure 27 communicates with the through hole 251. The third enclosure 27 extends the radial limiting height of the pulverizing blade, improving the coaxiality and stability of the pulverizing blade during operation. In addition, the third enclosure 27 also plays a role in laterally shielding the food, preventing the food from being directly thrown onto the top of the pulverizing blade shaft 35.

[0068] In a preferred embodiment of the present invention, reference is made to... Figure 3 , 4 8, 9, The second mounting part includes a screw-in groove 2526 provided on the inner side of the second enclosure 2523 and a screw-in rib 2524 radially protruding outward on the outer side wall 2522 of the second cup body 22, wherein the second enclosure 2523 extends into the U-shaped noise reduction cavity 4. (Refer to...) Figure 3 , 4 The engagement groove 2526 is formed by combining horizontal and vertical ribs to form an L-shaped engagement groove 2526. Multiple L-shaped engagement grooves 2526 are spaced apart along the inner side of the second enclosure wall 2523. The upper surface of the horizontal rib of the engagement groove 2526 is also provided with a sensing protrusion, and the lower surface of the engagement rib 2524 is provided with a sensing groove adapted to the sensing protrusion. This ensures that after the second cup body 22 and the second enclosure wall 2523 are aligned and installed through the engagement groove 2526 and the engagement rib 2524, the engagement rib 2524 will not come out of the engagement groove 2526 during operation, causing the second cup body 22 to fall off.

[0069] The engagement groove 2526 and engagement rib 2524 ensure stable fit between the second cup body 22 and the lid 25, while also providing a simple and convenient screw-fit structure. Furthermore, the engagement groove 2526, located inside the second enclosure 2523, allows for lateral shielding of any spillage of food from the second cup body 22, preventing it from splashing into the first cup body 21. Typically, for ease of installation, the second cup body 22 and lid 25 are loosely fitted. Therefore, the second enclosure 2523 extends into the U-shaped noise reduction cavity 4, lowering the center of gravity of the second cup body 22 and effectively blocking noise generated by the collision between the second cup body 22 and the second enclosure 2523.

[0070] Furthermore, in some embodiments of the present invention, in order to further reduce the height of the host machine 1 and improve the stability of the food processing machine during operation, the outer bottom wall 2521 of the recess 252 is set not higher than the top wall of the first cup body 21. If the outer edge of the cup mouth of the first cup body 21 is also provided with a lug (not shown in the figure), then the fact that the outer bottom wall 2521 of the recess 252 is not higher than the top wall of the first cup body 21 is equivalent to the fact that the outer bottom wall 2521 of the recess 252 is not higher than the top surface of the lug.

[0071] In some embodiments of the present invention, reference is made to Figures 1 to 3 To improve the working stability of the first crusher 31, a first positioning post 211 that cooperates with the first crusher 31 is provided on the inner bottom surface of the first cup body 21; to improve the working stability of the second crusher 32, a second positioning post 221 that cooperates with the second crusher 32 is provided inside the second cup body 22. A first radial swing gap L1 is provided between the first crusher 31 and the through hole 251 of the cup lid 25, and a second radial swing gap L2 is provided between the second crusher 32 and the through hole 251 of the cup lid 25. The lateral offset difference between the central axis of the first positioning post 211 and the central axis of the second positioning post 221 is L3, wherein the smaller of L1 and L2 is greater than or equal to L3. The food processing machine provided by the present invention requires two different pulverizing blades to be adapted to the through hole 251 of a single cup lid 25. In order for the blade shaft 35 of the first pulverizing blade 31 and the blade shaft 35 of the second pulverizing blade 32 to pass through the through hole 251 of the cup lid 25 and be connected to the motor 11 of the main unit 1, a first radial swing gap L1 is provided between the first pulverizing blade 31 and the through hole 251 of the cup lid 25, and a second radial swing gap L2 is provided between the second pulverizing blade 32 and the through hole 251 of the cup lid 25.

[0072] Meanwhile, due to manufacturing and installation tolerances in the positions of the second positioning post 221 and the first positioning post 211 in the first cup body 21, and because the fit between the second cup body 22 and the cup lid 25 is loose, the positioning shaft of the second cup body 22 and the through hole 251 of the cup lid 25 are not on the same axis, nor are the positioning shaft of the first cup body 21 and the through hole 251 of the cup lid 25. Therefore, in order to compensate for the manufacturing and installation tolerances of the two positioning posts and the deviations in the fit between the cup lid 25 and the second cup body 22, and to ensure that the second crushing blade 32 and the first crushing blade 31 can pass smoothly through the through hole 251 of the cup lid 25 and be connected to the main unit 1, the lateral offset difference between the central axis of the first positioning post 211 and the central axis of the second positioning post 221 is set to L3, where the smaller of L1 and L2 is greater than or equal to L3. If L2 is less than L1 and L2 is less than L3, then the second crushing blade 32 will not be able to pass through the through hole 251 of the cup lid 25 and be connected to the main unit 1 for transmission. If L1 is less than L2 and L1 is less than L3, then the first crushing blade 31 will not be able to pass through the through hole 251 of the cup lid 25 and be connected to the main unit 1 for transmission. If L1 is equal to L2 and both L1 and L2 are less than L3, then neither the first crushing blade 31 nor the second crushing blade 32 can pass through the through hole 251 of the cup lid 25 and be connected to the main unit 1 for transmission. Preferably, L3 is 0, that is, the first positioning post 211, the second positioning post 221, and the through hole 251 of the cup lid 25 are coaxially arranged.

[0073] It is also understood that, in some embodiments of the present invention, reference is made to... Figure 10-12 The food processing machine also includes a third cup body 23 that is replaceable and detachably connected to the second mounting part. The second cup body 22 and the third cup body 23 are detachably fitted together to form an assembly. The assembly is housed in the first cup body 21, and a U-shaped noise reduction cavity 4 is formed between the assembly and the first cup body 21.

[0074] The food processor provided by this invention includes a second cup body 22 and a third cup body 23 housed within a first cup body 21. The second cup body 22 and the third cup body 23 are replaceably fixed to a second mounting part. The capacities of the second cup body 22 and the third cup body 23 are smaller than the capacity of the first cup body 21, thus meeting users' needs for preparing ingredients of different capacities. For large-capacity ingredients, the larger-capacity first cup body 21 is selected for processing; for small-capacity complementary food preparation, the second cup body 22 or the third cup body 23 is selected, achieving multi-functionality and wide applicability. Furthermore, different cup bodies can be selected for different types of ingredients, thus solving the problem of flavor mixing. By providing a second mounting part on the cup lid 25, the second cup body 22 and the third cup body 23 can be positioned during processing, improving stability and preventing the user from removing the cup lid 25 along with the main unit 1 after processing, avoiding inconvenience. It also prevents the pulverizing blades in the second cup body 22 or the third cup body 23 from being exposed, thus improving safety.

[0075] The second cup 22 and the third cup 23 can be detachably fitted together to form a combined unit, allowing for convenient storage. Furthermore, the second cup 22 and the third cup 23 can be used separately, making independent cleaning easier. After using the second cup 22, the third cup 23 can be used directly. This allows for cleaning of each cup after preparing multiple types of ingredients, making cleaning more convenient. The combined unit is housed within the first cup 21, saving space and facilitating storage. It also prevents dust accumulation on the second and third cups 22 and 23 when not in use, ensuring easy access for future use.

[0076] The second cup 22 and the third cup 23 of this solution are connected in a nested configuration. Compared with the existing bidirectional cup, it does not completely occupy the overall axial space of the meat grinder bowl, and can expand to include more cups.

[0077] Specifically, a third positioning post 231 is provided inside the third cup body 23. Normally, the third positioning post 231 is coaxially arranged with the second positioning post 221, and the second cup body 22 and the third cup body 23 can share the second pulverizing blade 32. However, if the heights of the second cup body 22 and the third cup body 23 are different, or to prevent cross-contamination of flavors between the ingredients in the second cup body 22 and the third cup body 23, a third pulverizing blade 33 can be separately provided inside the third cup body 23. The lateral offset difference between the center axis of the third positioning post 231 and the center axis of the first positioning post 211 is also L3. A first radial swing gap L1 is provided between the first pulverizing blade 31 and the through hole 251 of the cup lid 25, and a second radial swing gap L2 is provided between the third pulverizing blade 33 and the through hole 251 of the cup lid 25. L1, L2, and L3 still satisfy the condition that the smaller of L1 and L2 is greater than or equal to L3.

[0078] Furthermore, regarding the way the second cup body 22 and the third cup body 23 are nested within the first cup body 21, the present invention provides the following three embodiments:

[0079] Example 1: The second cup 22 is sunk into the third cup 23 from its open end, with the sidewall of the second cup 22 fitting snugly against the sidewall of the third cup 23. By sunk the second cup 22 into the third cup 23 from its open end, and with the sidewall of the second cup 22 fitting snugly against the sidewall of the third cup 23, the shared height of the second cup 22 and the third cup 23 can be further increased, thereby saving space occupied by the assembly. Moreover, by using the sidewalls to achieve the snug fit, the user can simply stack the second cup 22 and the third cup 23 after use, making storage convenient and effortless.

[0080] Specifically, for example, refer to Figure 10 The side wall of the second cup body 22 may have an outwardly protruding step, which is exposed from the open end of the third cup body 23 and rests on the open end face of the third cup body 23.

[0081] Alternatively, the side wall of the second cup body 22 is provided with an outwardly protruding step portion, and the side wall of the third cup body 23 is also provided with an outwardly protruding step portion. The step portion of the second cup body 22 is fitted inside the step portion of the third cup body 23 and rests on the step portion of the third cup body 23.

[0082] By incorporating a stepped portion on the second cup body 22, the stepped portion of the second cup body 22 overlaps with the stepped portion of the third cup body 23, providing axial restraint and improving the stability of the assembled unit after storage. The stepped portion of the second cup body 22 protrudes from the open end of the third cup body 23, allowing users to easily remove the second cup body 22 and separate the assembled unit. This operation is convenient and effortless, and also facilitates making the heights of the second cup body 22 and the third cup body 23 as close as possible, enabling the sharing of a single shredder and simplifying the structure. The stepped portion of the second cup body 22 fits inside the stepped portion of the third cup body 23, further increasing the overlap height of the two cup bodies, thereby further reducing the space occupied by the assembled unit and saving storage space.

[0083] Example 2: Reference Figure 11 The openings of the third cup body 23 and the second cup body 22 face the same direction. The side wall of the third cup body 23 is sleeved on the support rib 29 of the second cup body 22. The outer bottom wall 2521 of the second cup body 22 is provided with a ring-shaped support rib 29. The second cup body 22 and the third cup body 23 are sleeved together through the support rib 29.

[0084] The second cup body 22 and the third cup body 23 are connected by a support rib 29. When the second cup body 22 is placed on the work surface, the support rib 29 provides support for the second cup body 22. In the stored state, the support rib 29 serves as a connecting part to connect the second cup body 22 and the third cup body 23, achieving efficient use of the support rib 29. There is no need to set separate connecting parts on other parts of the second cup body 22, resulting in a simple structure.

[0085] Example 3: Reference Figure 12 The openings of the third cup body 23 and the second cup body 22 face opposite directions. The outer bottom wall 2521 of the third cup body 23 and the outer bottom wall 2521 of the second cup body 22 are both provided with annular support ribs 29, and the two support ribs 29 are fitted together.

[0086] By having the openings of the third cup 23 and the second cup 22 face opposite directions, the operation of the second cup 22 and the third cup 23 is not limited by the socketed form. Not only can the second cup 22 and the third cup 23 remain socketed when the food processing machine is idle, but they can also remain socketed when processing is required using either the second cup 22 or the third cup 23. Furthermore, the lower cup can support the upper cup, improving the stability of the operation.

[0087] To lower the center of gravity of the entire machine and prevent the assembled unit from tilting or tipping over during operation of the main unit 1 or during transportation, thereby improving the working stability of the food processing machine, the present invention provides the following two implementation schemes:

[0088] Implementation Scheme 1: The bottom wall of the second cup body 22 is located below half the height of the first cup body 21, thereby lowering the overall center of gravity of the first cup body 21, the second cup body 22, and the main unit 1 after they are assembled. (Reference) Figure 2 The height of the first cup body 21 is H1, and the height of the bottom surface of the second cup body 22 from the bottom surface of the first cup body 21 is H2, where H2 is less than or equal to half of H1.

[0089] Implementation Scheme 2: By making the top surface of the second cup body 22 lower than the top surface of the first cup body 21, it is beneficial to lower the center of gravity of the first cup body 21, the cup lid 25 and the main unit 1 after assembly.

[0090] In some embodiments of the present invention, since the volume of the second cup body 22 is smaller than that of the first cup body 21, and the second cup body 22 also needs to be suspended on the cup lid 25, in order to avoid the second cup body 22 being too heavy and causing the second cup body 22 to bend the cup lid 25 or break at the connection between the second cup body 22 and the cup lid 25, the side wall thickness of the second cup body 22 is set to be lower than that of the first cup body 21.

[0091] In some embodiments of the present invention, to reduce operating noise, the second cup 22 is typically housed within the first cup 21 during operation. Therefore, in this solution, to improve the visibility of the second cup 22 during operation and facilitate observation of the food preparation process within the second cup 22 through the first cup 21, both the first cup 21 and the second cup 22 are made of a transparent material. The transparent material can be glass or food-grade transparent plastic. The first cup 21 and the second cup 22 can use the same transparent material or different transparent materials; this will not be elaborated further here.

[0092] In some embodiments of the present invention, reference is made to Figure 6 , 7The second shredder 32 includes a shroud 35, blades mounted on the shroud 35, and a baffle 39 fixed to the outer periphery of the shroud 35. The baffle 39 has a blunt end and extends obliquely upward along the rotation direction of the shroud 35. During the rotation of the shroud 35, the material located in front of the baffle 39 is pushed forward and downward by the combined action of the blunt end and the lower surface of the baffle 39, thereby preventing the material from remaining at a certain height and increasing the probability of the material colliding with the cutting edge 361 of the first blade 36, so that the material is effectively cut. The material located behind the baffle 39 falls as the shroud 35 rotates and collides with the first blade 36, thus being effectively cut. Therefore, under the disturbance of the baffle plate 39, the material is cut by the first blade 36 in a circulating manner from top to bottom. At the same time, the baffle plate 39 can press down the material to prevent it from splashing upwards onto the cup lid 25, which makes the material fully disturbed in the cup body, increasing the probability of contact between the food and the cutting edge 361 of the first blade 36. During the rotation of the cutter shaft 35, the first blade 36 continuously cuts the material, improving the crushing effect.

[0093] Specifically, the turbulence deflector 39 and the first blade 36 are staggered along the rotation direction of the cutter shaft 35 to increase turbulence and cutting effect. The lowest point of the turbulence deflector 39 is close to the cutting edge 361 of the first blade 36, so that the material pushed downward by the turbulence deflector 39 can be cut by the first blade 36 more directly and quickly, increasing the cutting efficiency.

[0094] Furthermore, the second crusher 32 also includes a second blade 37 located above the baffle 39. The first blade 36, the second blade 37, and the baffle 39 are staggered along the rotation direction of the blade shaft 35, and the cutting edge 361 of the second blade 37 is positioned facing the side of the baffle 39.

[0095] By setting a second blade 37 above the baffle 39, the material above the baffle 39 can be fully cut. The cutting edge 361 of the second blade 37 is set to face one side of the baffle 39 to prevent the material above from splashing upwards onto the cup lid 25 during the cutting process.

[0096] Furthermore, the second crusher 32 also includes a third blade 38 located between the baffle 39 and the first blade 36, the third blade 38 extending horizontally outward from the blade shaft 35.

[0097] The third blade 38, together with the first blade 36, cuts the material pressed down by the baffle 39, increasing the cutting effect on the lower layer of material. The third blade 38 extends horizontally, which can increase the cutting effect on the material between the baffle 39 and the first blade 36 without affecting the collision between the material and the first blade 36, thus improving the crushing effect.

[0098] In some embodiments of the present invention, reference is made to Figure 5 , 6The food processor also includes a fourth cup body 24 detachably mounted above the main unit 1, and the fourth cup body 24 is equipped with a fourth pulverizing blade 34. By setting the fourth cup body 24, the utilization rate of the main unit 1 is further increased, the function of the food processor is expanded, and its application is more extensive.

[0099] Specifically, the first cup 21 is a grinding cup, and the top of the main unit 1 is provided with a flip cover 12. When the flip cover 12 is open, the connector 13 on the top of the main unit 1 is exposed and coupled to the connector 13 inside the cup seat of the grinding cup to realize the transmission of the fourth pulverizing blade 34. When the flip cover 12 is closed, it can protect the connector 13. On the one hand, it can prevent the connector 13 from dust in the non-working state; on the other hand, it can prevent the exposed rotation of the connector 13 from causing a safety risk to the user when the first cup 21, the second cup 22, or the third cup 23 is working.

Therefore, they should not be construed as limitations on this invention.

[0101] In some embodiments of the present invention, in addition to the need for multiple cups, users now also require different speeds for different ingredients. For example, relatively high speeds are needed to grind meat and vegetables, while relatively low speeds are needed for kneading dough and beating eggs. To this end, the food processor is also equipped with a two-stage reduction gearbox and two output shaft holes, so that the first grinding blade 31 is engaged with the first output shaft hole, and the secondary grinding blade is engaged with the second output shaft hole. This allows the two output shaft holes to rotate at different speeds for grinding specific ingredients, further meeting the user's need for a multi-purpose machine.
