Description

Technical Field

[0001] The invention relates to the technical field of pulverizing devices, and in particular to a food processor with multiple functions. Background Art

[0002] In recent years, as users' pursuit of quality of life and healthy food has improved, people are more and more fond of making healthy food at home. For example, when people make meat-filled food, they often use commercial meat grinders in the vegetable market to grind it or buy it home and cut it with a knife. However, due to the poor sanitary environment of the former, the merchants will not clean the machine or meat, resulting in certain food hygiene problems in the minced meat, while the latter requires more manpower and time. Therefore, the emergence of household electric meat grinders has solved the above problems, entered thousands of households and become one of the favorite kitchen appliances of many families.

[0003] However, the meat grinder bowl used in the existing household meat grinder is suitable for mincing large amounts of meat and vegetables. When using the traditional meat grinder bowl to prepare small-volume complementary foods, the ingredients of the complementary foods are often only spread on the bottom of the meat grinder bowl, and may even be lower than the bottommost blade, resulting in poor results in making complementary foods.

[0004] To this end, the patent document with application number CN202220362985.2 discloses a meat grinder and a multifunctional meat grinder, including: a casing, a cover, a meat grinder bowl, a driving device, a knife holder and a cup body, the driving device is arranged in the casing, the lower end of the casing is inserted into the groove on the cover body, the cover body is arranged on the top of the meat grinder bowl, the upper and lower ends of the cup body are open structures, and a partition is connected inside, and the top surface of the partition and the upper end of the cup body and the bottom surface and the lower end of the cup body respectively form a meat grinder cavity, the cup body is placed in the meat grinder bowl, and the top of the cup body is in contact with the cover body. The size of the cup body of the patent is smaller than that of the meat grinder bowl, which is convenient for the mincing of small amounts of supplementary food ingredients. When a large amount of meat products is minced, the meat grinder cup body is taken out and minced by the meat grinder bowl, so as to realize the multifunctional mincing use needs, with good crushing effect, wide practicability and easy operation. The two meat grinder cavities of the meat grinder cup body can be used interchangeably, and the problem of cross-flavor can also be avoided.

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

[0006] 1. Since the meat grinder cup is a two-way cup and is placed on the inner bottom surface of the meat grinder bowl, and the upper end of the cup is only in contact with the annular flange at the bottom of the cover or maintains a small gap, this will result in the vibration generated by the stirring of the ingredients and the linkage of the main machine during the preparation of complementary foods, causing the meat grinder cup to move relative to the meat grinder bowl and produce abnormal noises, and even the complementary food knife will be offset relative to the output shaft hole of the main machine, resulting in the knife getting stuck.

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

[0008] 3. This two-way cup includes a first cup body and a second cup body with openings facing opposite directions. After the first cup body is used to prepare the food, if the two-way cup is directly turned upside down for use, the residual complementary food in the first cup body (usually pumpkin puree, yam puree and other liquid food with some liquid, which is convenient for babies to eat) will flow along the cup wall to the minced meat bowl, contaminating the minced meat bowl and increasing the difficulty of cleaning. If you want to solve this problem, you need to clean the two-way cup after using it once before you can use it again, which increases the complexity of production.

[0009] 4. The two-way cup occupies the entire axial space of the meat grinder bowl, and no other cup bodies can be further added. Therefore, the meat grinder bowl is limited to accommodating only one two-way cup, and it is impossible to expand more functional cups. Summary of the invention

[0010] The object of the present invention is to provide a multi-functional food processor, which aims to meet the multi-functional production requirements of different capacities such as minced meat and supplementary food, and solve the problem of loud abnormal noise of supplementary food cups in the prior art.

[0011] To achieve the above-mentioned purpose, the present invention provides a multi-functional food processing machine, characterized in that it comprises: a first cup body; a second cup body, the second cup body is accommodated in the first cup body; a cup cover, the cup cover is closed on the top of the first cup body; a main unit, a motor is arranged in the main unit, and the main unit is installed on the cup cover; a first crushing knife, the first crushing knife is arranged in the first cup body, and the top of the knife shaft of the first crushing knife is connected to the motor by transmission; a second crushing knife, the second crushing knife is arranged in the second cup body, and the knife shaft height of the first crushing knife is greater than the knife shaft height of the second crushing knife; the cup cover comprises a first mounting portion and a second mounting portion arranged inside the first mounting portion, the first cup body is limitedly matched with the first mounting portion, and the second cup body is detachably connected with the second mounting portion; the second cup body is hoisted below the cup cover 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 chamber between the second cup body and the first cup body, and the plumb bob projection of the second cup body falls within the plumb bob projection range of the rotating space formed by the rotation of the first crushing knife.

[0012] The multi-functional food processor provided by the present invention can achieve the separation of meat and vegetables, supplementary food, etc. by setting a first cup body and a second cup body, thereby preventing the problem of mixed flavors in a single cup. The second cup body is accommodated in the first cup body, which solves the problem of storing multiple cups. At the same time, by setting the first crushing knife and the second crushing knife to have different knife shaft heights, the two different crushing knives are adapted to cups with different capacities, thereby improving the adaptability of the crushing knife to different cup bodies and enhancing the crushing effect. In this food processor, by setting a first mounting portion and a second mounting portion provided on the inner side of the first mounting portion on the cup cover, the first cup body is limitedly matched with the first mounting portion, and the second cup body is detachably connected to the second mounting portion, thereby achieving the function of a single cup cover being adapted to multiple cup bodies. Compared with the solution in the prior art that a large cup is adapted to a large cup cover and a small cup is adapted to a small cup cover, a small cup cover is omitted, and the cost is lower. The second cup body is hoisted under the cup cover and the outer bottom surface of the second cup body is suspended relative to the inner bottom surface of the first cup body. First, the outer bottom surface of the second cup body is avoided from contacting with the inner bottom surface of the first cup body, which causes abnormal noise caused by mutual friction between the two during operation; second, a U-shaped noise reduction cavity is formed between the second cup body and the first cup body. The noise generated when the second crushing knife in the second cup body and the food are crushed needs to be weakened by the U-shaped noise reduction cavity before being transmitted to the outside of the first cup body, thereby achieving the effect of noise reduction and improving the user experience; third, due to the hoisting of the second cup body, the gravity of the cup cover is increased, which effectively prevents the user from accidentally taking the cup cover away from the top of the first cup body when taking away the host, thereby solving the installation risk caused by the second crushing knife in the second cup body being exposed and still rotating by inertia. In order to further reduce the noise problem of the second cup body in the working state, the plumb bob projection of the second cup body is also set to fall within the plumb bob projection range of the rotating space formed by the rotation of the first crushing knife under this scheme, that is, the bottom area of ​​the second cup body is smaller than the outer peripheral area of ​​the rotating space of the first crushing knife. Normally, the first crushing blade must fit in the gap between the inner side wall of the first cup body. In this solution, the plumb bob projection of the second cup body is set to fall within the plumb bob projection range of the rotating space formed by the rotation of the first crushing blade, and the lateral width of the noise reduction cavity between the side wall of the second cup body and the side wall of the first cup body is widened to increase 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 side wall of the first cup body, thereby increasing the working noise generated by the second cup body 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 cooperation with the first cup body, the cup cover includes a concave cavity for accommodating the main unit, the outer wall of the concave cavity is gap-fitted with the first surrounding wall, and the second mounting portion is arranged on the outer wall of the concave cavity.

[0014] By setting the first mounting part as the first surrounding wall that cooperates with the radial limiting of the first cup body, the radial limiting of the cup cover and the first cup body is achieved, and the cup cover is prevented from radially separating from the first cup body during the working process of the first cup body, thereby causing the food to splash. At the same time, by setting a concave cavity to accommodate the main machine, on the one hand, the radial limiting of the main machine is performed, and on the other hand, the working center of gravity of the main machine is reduced, thereby improving the working stability of the food processor. On this basis, by setting the clearance between the outer wall of the concave cavity and the first surrounding wall, the second mounting part is arranged on the outer wall of the concave cavity, on the one hand, when the noise generated by the main machine is transmitted radially outward, it is first transmitted to the outside through the above-mentioned gap, and has a certain noise reduction effect on the main machine; on the other hand, the second mounting part is directly installed on the outer wall of the concave cavity, eliminating the cost of separately setting the second mounting part on the cup cover to install the second cup body, and the main machine is installed in the concave cavity and the second cup body is installed outside, which is a dual-purpose. In addition, the radial limiting of the second cup body by the outer wall of the concave cavity avoids the radial deviation of the second cup body, improves the coaxiality of the second cup body, the second crushing knife and the through hole of the cup cover, and effectively avoids the problem of knife jamming.

[0015] Preferably, the outer wall of the concave 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 portion is located on the second surrounding wall.

[0016] In order 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 set not higher than the top wall of the first cup body. On this basis, by setting an extended second surrounding wall on the outer bottom wall of the concave cavity, the second mounting portion is located on the second surrounding wall, which is conducive to lowering the center of gravity of the second cup body, and then lowering the overall center of gravity of the main unit, the cup cover, and the second cup body, so that the cup cover and the first cup body are more stably matched, and the overall food processor works more stably when using the second cup body to make food.

[0017] Preferably, the second mounting portion includes a screw-in groove provided on the inner side surface of the second surrounding wall and a screw-in rib provided on the outer side wall of the second cup body and protruding radially outward, and the second surrounding wall extends into the U-shaped noise reduction cavity.

[0018] The coordination stability of the second cup body and the cup cover can be achieved by cooperating with the screw-in groove and the screw-in rib, and at the same time, the screw-in structure is simple and easy to install. At the same time, the screw-in groove is arranged on the inner side of the second surrounding wall, which is conducive to the second surrounding wall to laterally shield the food in the second cup body even if there is a small amount of splashing, so as to prevent the food from splashing into the first cup body. Generally, in order to facilitate the installation convenience of the second cup body and the cup cover, they are usually loosely installed. Therefore, the second surrounding wall extends into the U-shaped noise reduction cavity, which can not only reduce the working center of gravity of the second cup body, but also can block the noise generated by the collision between the second cup body and the second surrounding wall through the U-shaped noise reduction cavity.

[0019] Preferably, a first positioning column cooperating with a first crushing knife is provided on the inner bottom surface of the first cup body, a second positioning column cooperating with a second crushing knife is provided on the inner bottom surface of the second cup body, a first radial swing gap L1 is provided between the first crushing knife and the through hole of the cup cover, a second radial swing gap L2 is provided between the second crushing knife and the through hole of the cup cover, and the lateral offset difference between the central axis of the first positioning column and the central axis of the second positioning column is L3, wherein the smaller value of L1 and L2 is greater than or equal to L3.

[0020] In order to improve the working stability of the first crushing knife, a first positioning column cooperating with the first crushing knife is arranged on the inner bottom surface of the first cup body; in order to improve the working stability of the second crushing knife, a second positioning column cooperating with the second crushing knife is arranged in the second cup body. In the food processing machine provided by the present invention, the through hole of a single cup cover needs to be adapted to two different crushing knives. In order for the knife shaft of the first crushing knife and the knife shaft of the second crushing knife to gather energy through the through hole of the cup cover and be connected to the motor transmission of the host, a first radial swing gap L1 is arranged between the first crushing knife and the through hole of the cup cover, and a second radial swing gap L2 is arranged between the second crushing knife and the through hole of the cup cover. At the same time, due to the manufacturing and installation tolerances of the position of the second positioning column in the second cup body, the manufacturing and installation tolerances of the position of the first positioning column in the first cup body, and the loose fit between the second cup body and the cup cover, the positioning shaft of the second cup body and the through hole of the cup cover are not located on the same axis, and the positioning shaft of the first cup body and the through hole of the cup cover are not located on the same axis. Therefore, in order to compensate for the manufacturing and installation tolerances of the two positioning posts and the deviation of the cup cover of the second cup body, and to ensure that the second crushing knife and the first crushing knife can pass through the through hole of the cup cover and be connected to the main machine, the lateral offset difference between the central axis of the first positioning post and the central axis of the second positioning post is set to L3, wherein the smaller value of L1 and L2 is greater than or equal to L3. If the value of L2 is less than L1, and L2 is less than L3, then the second crushing knife will not be able to pass through the through hole of the cup cover and be connected to the main machine; if the value of L1 is less than L2, and L1 is less than L3, then the first crushing knife will not be able to pass through the through hole of the cup cover and be connected to the main machine; if the value of L1 is equal to L2, and L1 or L2 is less than L3, then the first crushing knife and the second crushing knife will not be able to pass through the through hole of the cup cover and be connected to the main machine.

[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 body is located below half the height of the first cup body, thereby lowering the overall center of gravity of the first cup body, the second cup body, the cup cover and the main unit after they are matched. By having the top surface of the second cup body be lower than the top surface of the first cup body, it is helpful to lower the center of gravity of the first cup body, the cup cover and the main unit after assembly, thereby achieving a downward shift in the center of gravity of the entire machine, preventing the entire assembly from tilting or tipping over during the operation of the main unit or the transportation of the entire machine, and helping to improve the working stability of the food processor.

[0023] Preferably, the second crushing knife includes a knife shaft, a blade arranged on the knife shaft and a spoiler fixed on the outer periphery of the knife shaft, the spoiler has a blunt end at the front end of the knife shaft in the rotation direction, the spoiler extends obliquely upward along the rotation direction of the knife shaft, and the blade includes a first blade located below the spoiler, and the first blade has a cutting edge at the front end of the knife shaft in the rotation direction.

[0024] The second crushing blade provided by the present invention also includes a spoiler, which has a blunt end and extends upward along the rotation direction of the blade shaft. During the rotation of the blade shaft, the material located in front of the spoiler is pushed forward and downward under the combined action of the blunt end and the lower surface of the spoiler, thereby preventing the material from staying at a certain height, increasing the probability of the material colliding with the edge of the first blade, and effectively cutting the material; the material located behind the spoiler falls as the blade shaft rotates, collides with the first blade, and is effectively cut. Therefore, under the disturbing action of the spoiler, the material is cut by the first blade in a cycle from top to bottom, and the spoiler can press the material down at the same time to prevent the material from splashing upward to the cup cover, so that the material is fully disturbed in the cup body, increasing the contact probability of the food and the edge of the first blade. During the rotation of the blade shaft, the first blade cyclically cuts the material to improve the crushing effect.

[0025] Preferably, the side wall thickness of the second cup body is less than the side wall thickness of the first cup body; and / or, both the first cup body and the second cup body are made of transparent materials.

[0026] Since the volume of the second cup body is smaller than that of the first cup body, and the second cup body needs to be hoisted on the cup cover, in order to avoid the second cup body being too heavy and causing the second cup body to bend the cup cover or the connection between the second cup body and the cup cover to break, the side wall thickness of the second cup body is set to be lower than the side wall thickness of the first cup body.

[0027] In addition, in order to reduce the working noise, the second cup body is usually placed inside the first cup body when the second cup body is in working state. Therefore, in order to improve the visibility of the second cup body in working state and facilitate the user to observe the preparation of the food in the second cup body through the first cup body, the first cup body and the second cup body are both made of transparent materials.

[0028] Preferably, it also includes a third cup body which is replaceably connected to the second mounting portion and detachably connected to the second cup body, the second cup body and the third cup body are detachably socketed to form a combination, the combination is accommodated in the first cup body, and a U-shaped noise reduction cavity is formed between the combination and the first cup body.

[0029] The food processor provided by the present invention comprises a second cup body and a third cup body contained in a first cup body, the second cup body and the third cup body can be replaced and fixed to the second mounting portion, the capacity of the second cup body and the third cup body are respectively smaller than the capacity of the first cup body, thereby satisfying the user's preparation requirements for ingredients of different capacities, selecting the first cup body with a larger capacity for large-capacity ingredient preparation, and selecting the second cup body or the third cup body for small-capacity supplementary food preparation, thereby achieving multi-function and wide practicality. Moreover, different cup bodies can be selected for preparation of different types of ingredients, thereby solving the problem of food odor contamination. By arranging the second mounting portion on the cup cover, the second cup body and the third cup body can be positioned during the processing process, thereby improving the stability of use, and avoiding the user from removing the cup cover when removing the main machine after the food processing is completed, thereby avoiding causing trouble to the user, and also avoiding the danger of the crushing knife in the second cup body or the third cup body being exposed, thereby improving the safety of use. The second cup body and the third cup body can be detachably sleeved to form a combination body, which is convenient for storage. Moreover, the second cup body and the third cup body can be used separately, which is more convenient for independent cleaning. After using the second cup body, the third cup body can be used directly. After preparing multiple types of food, each cup body can be cleaned, which is more convenient. The combination body is accommodated in the first cup body, which saves space and is convenient for storage. At the same time, it avoids the second cup body and the third cup body from being compressed by dust when they are idle, which is convenient for next use.

[0030] Preferably, the food processor further comprises a fourth cup body detachably mounted above the main machine, wherein a fourth crushing knife is disposed in the fourth cup body.

[0031] By arranging the fourth cup body, the utilization rate of the main machine is further increased, the function of the food processing machine is expanded, and the application is more extensive. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0052] It should be noted that many specific details are set forth in the following description to facilitate 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 protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0053] like Figure 1-13 As shown, the present invention provides a multi-functional food processor in one embodiment, including a main machine 1 with a motor 11, and the main machine 1 is installed on a cup cover 25. The cup body assembly 2 includes at least a first cup body 21 and a second cup body 22. The cup cover 25 covers the first cup body 21, and the second cup body 22 is placed in the first cup body 21. A concave cavity 252 is provided on the cup cover 25, and the main machine 1 is accommodated in the concave cavity 252. At the same time, by providing the concave cavity 252 to accommodate the main machine 1, on the one hand, the radial position of the main machine 1 is limited, and on the other hand, the working center of gravity of the main machine 1 is reduced, thereby improving the working stability of the food processor. In this solution, the first cup body 21 is used to make minced meat or chopped vegetables with a large capacity requirement, and the second cup body 22 is used to make supplementary food with a smaller capacity, such as pumpkin puree, yam puree, etc. for babies. By providing the first cup body 21 and the second cup body 22, it is achieved that meat and vegetables, supplementary food, etc. can be beaten separately to prevent the problem of single cup odor.

[0054] Specifically, the cup cover 25 includes a first mounting portion and a second mounting portion provided inside the first mounting portion. When the first cup body 21 is in operation, the first cup body 21 is limitedly matched with the first mounting portion, and the second cup body 22 is located outside the first cup body 21. The crushing assembly 3 includes at least a first crushing knife 31 and a second crushing knife 32. The top of the knife shaft 35 of the first crushing knife 31 provided in the first cup body 21 passes through the through hole 251 of the cup cover 25 and is connected to the motor 11 for transmission to realize the transmission of the first crushing knife 31. When the second cup body 22 is in operation or storage, the second cup body 22 is accommodated in the first cup body 21 and the second crushing knife 32 is provided in the second cup body 22, the first cup body 21 is limitedly matched with the first mounting portion, the second cup body 22 is detachably connected with the second mounting portion, the second cup body 22 is hoisted below the cup cover 25, and the outer bottom surface of the second cup body 22 is suspended relative to the inner bottom surface of the first cup body 21 to form a U-shaped noise reduction chamber 4 between the second cup body 22 and the first cup body 21. The second cup body 22 is accommodated in the first cup body 21, solving the problem of storing multiple cups.

[0055] By providing a first mounting portion and a second mounting portion provided on the inner side of the first mounting portion on the cup cover 25, the first cup body 21 is limitedly matched with the first mounting portion, and the second cup body 22 is detachably connected to the second mounting portion, thereby realizing the function of a single cup cover 25 being adapted to multiple cup bodies. Compared with the solution in the prior art that a large cup is adapted to a large cup cover 25 and a small cup is adapted to a small cup cover 25, a small cup cover 25 is omitted, and the cost is lower.

[0056] The second cup body 22 is hoisted under the cup cover 25 and the outer bottom surface of the second cup body 22 is suspended relative to the inner bottom surface of the first cup body 21. First, the contact between the outer bottom surface of the second cup body 22 and the inner bottom surface of the first cup body 21 is avoided, which causes abnormal noise caused by the friction between the two during operation; second, a U-shaped noise reduction chamber 4 is formed between the second cup body 22 and the first cup body 21. The noise generated when the second crushing knife 32 in the second cup body 22 and the food are crushed needs to first pass through the U-shaped noise reduction chamber 4 to weaken the sound waves and then transmit them to the outside of the first cup body 21, thereby achieving the effect of noise reduction and improving the user experience; third, due to the hoisting of the second cup body 22, the gravity of the cup cover 25 is increased, which effectively prevents the user from accidentally deviating or taking away the cup cover 25 from above the first cup body 21 when taking away the host 1, thereby solving the installation risk caused by the second crushing knife 32 in the second cup body 22 being exposed and still rotating by inertia in this case.

[0057] It should also be noted that in this solution, since the second cup body 22 is to be accommodated in the first cup body 21 and a U-shaped noise reduction chamber 4 is to be formed, it is necessary to set the first crushing knife 31 and the second crushing knife 32 to have different heights of the knife shaft 35. The different heights of the knife shaft 35 allow the two different crushing knives to fit cup bodies with different capacities, thereby improving the compatibility of the crushing knives with different cup bodies and enhancing the crushing effect.

[0058] At the same time, in order to further reduce the noise problem when the second cup body 22 is in the working state, the plumb projection of the second cup body 22 is also set in this solution to fall within the plumb projection range of the rotating space formed by the rotation of the first crushing knife 31, that is, the bottom area of ​​the second cup body 22 is smaller than the peripheral area of ​​the rotating space of the first crushing knife 31. Under normal circumstances, the first crushing knife 31 must be matched with the inner wall gap of the first cup body 21. In this solution, by setting the plumb projection of the second cup body 22 to fall within the plumb projection range of the rotating space formed by the rotation of the first crushing knife 31, the lateral width of the noise reduction cavity 4 between the side wall of the second cup body 22 and the side wall of the first cup body 21 is widened to increase the volume of the U-shaped noise reduction cavity 4, that is, the above-mentioned lateral width is wider than the gap between the first crushing knife 31 and the inner wall of the first cup body 21, thereby increasing the working noise generated by the second cup body 22 in the working state.

[0059] It is understandable that for some host machines 1 with smaller dimensions, that is, host machines 1 with relatively low height, it is also possible not to provide the cavity 252 in the cup cover 25 , but to provide a plane to adapt to the host machine 1 .

[0060] In some embodiments of the present invention, reference Figure 2 , the first mounting portion includes a first surrounding wall 26 for extending into the first cup body 21 and cooperating with the first cup body 21 in radial limiting. By setting the first mounting portion as the first surrounding wall 26 cooperating with the first cup body 21 in radial limiting, the radial limiting of the cup cover 25 and the first cup body 21 is achieved, so as to avoid the cup cover 25 radially separating from the first cup body 21 during the operation of the first cup body 21, thereby causing food to splash. In order to ensure the sealing between the cup cover 25 and the first surrounding wall 26, a sealing ring can also be sleeved on the outer periphery of the first surrounding wall 26. The clearance between the outer side wall 2522 of the concave cavity 252 and the first surrounding wall 26 is matched, so that when the noise generated by the main unit 1 is transmitted radially outward, it is first transmitted to the outside through the above-mentioned gap, which has a certain noise reduction effect on the main unit 1.

[0061] Regarding the specific structure in which the second mounting portion is disposed on the outer wall of the concave cavity 252, the present invention provides the following exemplary solutions:

[0062] The second mounting portion is arranged on the outer wall of the concave cavity 252, eliminating the cost of separately setting the second mounting portion on the cup cover 25 to mount the second cup body 22. The main unit 1 is mounted inside the concave cavity 252, and the second cup body 22 is mounted outside the concave cavity 252, which is a dual-purpose device. Among them, the outer wall of the concave cavity 252 includes an outer bottom wall 2521 and an outer side wall 2522. In addition, the outer wall of the concave cavity 252 radially limits the second cup body 22 to avoid radial deviation of the second cup body 22, thereby improving the coaxiality of the second cup body 22, the second crushing knife 32 and the through hole 251 of the cup cover 25, and effectively avoiding the problem of knife jamming.

[0063] Exemplary solution 1: Figure 1-4 As shown, the outer bottom wall 2521 is provided with a second surrounding wall 2523 extending downward, and the second mounting portion is located on the second surrounding wall 2523. In this scheme, the second mounting portion can be located on the inner side wall of the second surrounding wall 2523 or on the outer side wall 2522 of the second surrounding wall 2523, which is not specifically limited here. By setting the second surrounding wall 2523 extending downward on the outer bottom wall 2521 of the concave cavity 252, and the second mounting portion is located on the second surrounding wall 2523, it is beneficial to lower the center of gravity of the second cup body 22, and then lower the overall center of gravity of the host 1, the cup cover 25, and the second cup body 22, so that the cup cover 25 and the first cup body 21 are more stably matched, and the overall food processor works more stably when making food with the second cup body 22.

[0064] Exemplary solution 2: Regardless of whether there is a second surrounding wall 2523 extending downward on the outer bottom wall 2521 of the concave cavity 252, the second mounting portion is provided on the outer side wall 2522 of the concave cavity 252, that is, the concave cavity 252 partially extends into the second cup body 22. If the second surrounding wall 2523 is provided under this solution, the second surrounding wall 2523 extends into the second cup body 22, which is conducive to the formation of the second surrounding wall 2523 to block the food when it splashes upward, so that the food falls back, and the food is reduced from going out of the gap between the second surrounding wall 2523 and the second cup body 22. At the same time, the second surrounding wall 2523 improves the radial limit reliability of the second cup body 22. If the second surrounding wall 2523 is not provided under this solution, the cost of providing the second surrounding wall 2523 can be saved, so that the concave cavity 252 serves as both a component for accommodating the host 1 and a component for installing the second cup body 22.

[0065] Example 3: Reference Fig.13 The outer bottom wall 2521 of the cavity 252 first extends radially outward to the outer diameter of the cavity 252, and then extends downward to form a second surrounding wall 2523, and the second mounting portion is located on the second surrounding wall 2523. In this solution, compared with the exemplary solution 1, the second cup body 22 can be made with a relatively large capacity.

[0066] Specifically, the second mounting portion may include a screw-on rib 2524 disposed on the outer wall of the concave cavity 252 and a screw-on groove 2526 disposed on the second cup body 22. Of course, the screw-on rib 2524 and the screw-on groove 2526 may be relatively replaced. Alternatively, a first thread is disposed on the outer wall of the concave cavity 252, and a second thread engaged with the first thread is disposed on the second cup body 22. Here, no further description is given.

[0067] In a preferred embodiment of the present invention, reference is made to Figure 2 , 3The through hole 251 of the cup cover 25 is also provided with a third wall 27 extending downward, the interior of the third wall 27 is connected to the through hole 251, and the third wall 27 is used to extend the height of the radial limit of the crushing knife, thereby improving the coaxiality and stability of the crushing knife when working. In addition, the third wall 27 can also play a role in lateral shielding of food, preventing the food from being thrown directly onto the top of the knife shaft 35 of the crushing knife.

[0068] In a preferred embodiment of the present invention, reference is made to Figure 3 , 4 , 8, 9, the second mounting portion includes a screwing groove 2526 provided on the inner side of the second surrounding wall 2523 and a screwing rib 2524 provided on the outer side wall 2522 of the second cup body 22 and protruding radially outward, and the second surrounding wall 2523 extends into the U-shaped noise reduction cavity 4. Figure 3 , 4 The screwing groove 2526 is formed by combining the transverse ribs and the vertical ribs to form an L-shaped screwing groove 2526, and a plurality of L-shaped screwing grooves 2526 are arranged at intervals along the inner side surface of the second surrounding wall 2523. A sensing bump is also convexly provided on the upper surface of the transverse rib of the screwing groove 2526, and a sensing groove adapted to the sensing bump is provided on the lower surface of the screwing rib 2524, so that after the second cup body 22 and the second surrounding wall 2523 are aligned and installed through the screwing groove 2526 and the screwing rib 2524, the screwing rib 2524 will not fall out of the screwing groove 2526 during operation to cause the second cup body 22 to fall.

[0069] The coordination stability of the second cup body 22 and the cup cover 25 can be achieved by cooperating with the screw-in groove 2526 and the screw-in rib 2524, and at the same time, the screw-in structure is simple and easy to install. At the same time, the screw-in groove 2526 is arranged on the inner side of the second surrounding wall 2523, which is conducive to the food in the second cup body 22. Even if there is a small amount of splashing, it can be laterally shielded by the second surrounding wall 2523 to prevent the food from splashing into the first cup body 21. Generally, in order to facilitate the installation convenience of the second cup body 22 and the cup cover 25, it is usually loosely installed. Therefore, the second surrounding wall 2523 extends into the U-shaped noise reduction chamber 4, which can not only reduce the working center of gravity of the second cup body 22, but also can block the noise generated by the collision between the second cup body 22 and the second surrounding wall 2523 through the U-shaped noise reduction chamber 4.

[0070] Furthermore, in some embodiments of the present invention, in order to further reduce the height of the main unit 1 and improve the stability of the food processor during operation, the outer bottom wall 2521 of the concave cavity 252 is set not higher than the top wall of the first cup body 21. If a lug (not marked in the drawings) is further provided at the outer edge of the cup opening of the first cup body 21, then the outer bottom wall 2521 of the concave cavity 252 is not higher than the top wall of the first cup body 21, which is equivalent to the outer bottom wall 2521 of the concave cavity 252 being 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 In order to improve the working stability of the first crushing knife 31, a first positioning column 211 cooperating with the first crushing knife 31 is arranged on the inner bottom surface of the first cup body 21; in order to improve the working stability of the second crushing knife 32, a second positioning column 221 cooperating with the second crushing knife 32 is arranged in the second cup body 22. A first radial swing gap L1 is arranged between the first crushing knife 31 and the through hole 251 of the cup cover 25, and a second radial swing gap L2 is arranged between the second crushing knife 32 and the through hole 251 of the cup cover 25. The lateral offset difference between the central axis of the first positioning column 211 and the central axis of the second positioning column 221 is L3, wherein the smaller value of L1 and L2 is greater than or equal to L3. In the food processing machine provided by the present invention, the through hole 251 of a single cup cover 25 needs to be adapted to two different crushing knives. In order to gather energy for the knife shaft 35 of the first crushing knife 31 and the knife shaft 35 of the second crushing knife 32 to pass through the through hole 251 of the cup cover 25 and be transmission-connected with the motor 11 of the main machine 1, a first radial swing gap L1 is provided between the first crushing knife 31 and the through hole 251 of the cup cover 25, and a second radial swing gap L2 is provided between the second crushing knife 32 and the through hole 251 of the cup cover 25.

[0072] At the same time, due to the manufacturing and installation tolerances of the position of the second positioning column 221 in the second cup body 22, the manufacturing and installation tolerances of the position of the first positioning column 211 in the first cup body 21, and the loose fit between the second cup body 22 and the cup cover 25, the positioning axis of the second cup body 22 and the through hole 251 of the cup cover 25 are not located on the same axis, and the positioning axis of the first cup body 21 and the through hole 251 of the cup cover 25 are not located on the same axis. Therefore, in order to make up for the manufacturing and installation tolerances of the two positioning columns and the deviation of the fit of the cup cover 25 of the second cup body 22, and to ensure that the second crushing knife 32 and the first crushing knife 31 can pass through the through hole 251 of the cup cover 25 and be connected to the main machine 1, the lateral offset difference between the central axis of the first positioning column 211 and the central axis of the second positioning column 221 is set to L3, wherein the smaller value of L1 and L2 is greater than or equal to L3. If the value of L2 is less than L1, and L2 is less than L3, the second crushing knife 32 will not be able to pass through the through hole 251 of the cup cover 25 to be transmission-connected with the host 1; if the value of L1 is less than L2, and L1 is less than L3, the first crushing knife 31 will not be able to pass through the through hole 251 of the cup cover 25 to be transmission-connected with the host 1; if the value of L1 is equal to L2, and L1 or L2 is less than L3, the first crushing knife 31 and the second crushing knife 32 will not be able to pass through the through hole 251 of the cup cover 25 to be transmission-connected with the host 1. Preferably, the value of L3 is 0, that is, the first positioning column 211, the second positioning column 221, and the through hole 251 of the cup cover 25 are coaxially arranged.

[0073] It is also understood that, in some embodiments of the present invention, reference Figure 10-12 The food processor also includes a third cup body 23 which is replaceably connected to the second mounting portion and detachably connected to the second cup body 22. The second cup body 22 and the third cup body 23 are detachably fitted together to form a combination, which is accommodated in the first cup body 21. A U-shaped noise reduction chamber 4 is formed between the combination and the first cup body 21.

[0074] The food processor provided by the present invention comprises a second cup body 22 and a third cup body 23 contained in a first cup body 21, the second cup body 22 and the third cup body 23 can be replaced and fixed to the second mounting portion, the capacity of the second cup body 22 and the third cup body 23 are respectively smaller than the capacity of the first cup body 21, thereby satisfying the user's preparation requirements for ingredients of different capacities, selecting the first cup body 21 with a larger capacity for large-capacity ingredient preparation for processing, and selecting the second cup body 22 or the third cup body 23 for processing for small-capacity supplementary food preparation, thereby achieving multi-function and wide practicality. Moreover, different cup bodies can be selected for preparation of different types of ingredients, thereby solving the problem of food odor contamination. By arranging the second mounting portion on the cup cover 25, the second cup body 22 and the third cup body 23 can be positioned during the processing process, thereby improving the stability of use, and avoiding the user from removing the cup cover 25 when removing the host 1 after the food processing is completed, thereby avoiding causing trouble to the user, and also avoiding the danger of the crushing knife in the second cup body 22 or the third cup body 23 being exposed, thereby improving the safety of use.

[0075] The second cup body 22 and the third cup body 23 can be detachably sleeved to form a combination body, which is convenient for storage. Moreover, the second cup body 22 and the third cup body 23 can be used separately, which is more convenient for independent cleaning. After using the second cup body 22, the third cup body 23 can be used directly, and each cup body can be cleaned after preparing multiple types of ingredients, which is more convenient for cleaning. The combination body is accommodated in the first cup body 21, which saves space and is convenient for storage. At the same time, it avoids the accumulation of dust on the second cup body 22 and the third cup body 23 when they are idle, which is convenient for next use.

[0076] The second cup body 22 and the third cup body 23 of this solution are sleeved. Compared with the two-way cup in the prior art, it does not completely occupy the entire axial space of the minced meat bowl, and more cup bodies can be expanded.

[0077] Specifically, a third positioning column 231 is provided in the third cup body 23. Usually, the third positioning column 231 is coaxially arranged with the second positioning column 221, and the second cup body 22 and the third cup body 23 can share the second crushing knife 32. Of course, if the heights of the second cup body 22 and the third cup body 23 are inconsistent, or in order to prevent the food materials in the second cup body 22 and the third cup body 23 from odor contamination, the third crushing knife 33 can also be separately provided in the third cup body 23. The lateral offset difference between the center of gravity axis of the third positioning column 231 and the center axis of the first positioning column 211 is also L3, a first radial swing gap L1 is provided between the first crushing knife 31 and the through hole 251 of the cup cover 25, and a second radial swing gap L2 is provided between the third crushing knife 33 and the through hole 251 of the cup cover 25, and L1, L2, and L3 still satisfy: the smaller value of L1 and L2 is greater than or equal to L3.

[0078] Further, regarding the sleeve arrangement of the second cup body 22 and the third cup body 23 in the first cup body 21, the present invention provides the following three embodiments:

[0079] Embodiment 1: The second cup body 22 is sunk into the third cup body 23 from the open end of the third cup body 23, and the side wall of the second cup body 22 is sleeved with the side wall of the third cup body 23. By sinking the second cup body 22 into the third cup body 23 from the open end of the third cup body 23, and the side wall of the second cup body 22 is sleeved with the side wall of the third cup body 23, the shared height of the second cup body 22 and the third cup body 23 can be further increased, thereby saving the occupied space of the combination. Moreover, by using the side wall to achieve the sleeved fit, the user can directly stack the second cup body 22 and the third cup body 23 after use, which is convenient and labor-saving to store.

[0080] For example, refer to Fig.10 , the side wall of the second cup body 22 may be provided with a step portion 28 protruding outward, the step portion 28 is exposed from the open end of the third cup body 23 and is supported on the open end surface of the third cup body 23;

[0081] Alternatively, the side wall of the second cup body 22 is provided with a step portion 28 protruding outward, and the side wall of the third cup body 23 is also provided with a step portion 28 protruding outward. The step portion 28 of the second cup body 22 is sleeved on the inner side of the step portion 28 of the third cup body 23 and is supported by the step portion 28 of the third cup body 23.

[0082] By setting a step portion 28 on the second cup body 22, the step portion 28 of the second cup body 22 and the step portion 28 of the third cup body 23 can be overlapped, play a certain axial limit, improve the stability of the combination after storage, and the step portion 28 of the second cup body 22 is exposed from the open end of the third cup body 23, so that the user can take the second cup body 22 through the step portion 28 of the second cup body 22 to separate the combination, which is convenient and labor-saving to operate, and it is also convenient to make the height of the second cup body 22 as close as possible to the height of the third cup body 23, which is more conducive to sharing a crushing knife and simplifying the structure. The step portion 28 of the second cup body 22 is sleeved on the inner side of the step portion 28 of the third cup body 23, which further increases the overlapping height of the second cup body 22 and the third cup body 23, thereby further reducing the occupied space of the combination and saving storage space.

[0083] Example 2: Reference Fig.11 The openings of the third cup body 23 and the second cup body 22 are oriented in the same direction, the side walls of the third cup body 23 are sleeved on the support ribs 29 of the second cup body 22, the outer bottom wall 2521 of the second cup body 22 is convexly provided with an annular support rib 29, and the second cup body 22 and the third cup body 23 are sleeved together through the support ribs 29.

[0084] The support ribs 29 are provided and the second cup body 22 and the third cup body 23 are sleeved together through the support ribs 29. When the second cup body 22 is placed on the work surface, the support ribs 29 support the second cup body 22. In the storage state, the support ribs 29 serve as a connecting portion to sleeve the second cup body 22 and the third cup body 23, thereby realizing reasonable use of the support ribs 29. There is no need to separately provide a connecting portion at other portions of the second cup body 22, and the structure is simple.

[0085] Example 3: Reference Fig.12 The openings of the third cup body 23 and the second cup body 22 face oppositely, and 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 convexly provided with annular supporting ribs 29, and the two supporting ribs 29 are sleeved and matched.

[0086] By arranging the openings of the third cup body 23 and the second cup body 22 to face oppositely, the operation of the second cup body 22 and the third cup body 23 is not restricted by the socketing form. Not only can the second cup body 22 and the third cup body 23 remain socketed when the food processor is idle, but also when the second cup body 22 or the third cup body 23 is needed for processing, the second cup body 22 and the third cup body 23 can still remain socketed, and the cup body located below can support the cup body above, thereby improving the stability of operation.

[0087] In order to achieve the downward shifting of the center of gravity of the whole machine, prevent the assembly from tilting or tipping over during the operation of the main machine 1 or during the transportation of the whole machine, and improve the working stability of the food processing machine, the present invention provides the following two implementation schemes:

[0088] Embodiment 1: The bottom wall of the second cup body 22 is located below the half height of the first cup body 21, thereby lowering the center of gravity of the first cup body 21, the second cup body 22, the cup cover 25 and the main unit 1 after they are matched. Figure 2 The height of the first cup body 21 is H1, the height of the bottom surface of the second cup body 22 from the bottom surface of the first cup body 21 is H2, and H2 is less than or equal to half of H1.

[0089] Embodiment 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 helpful to lower the center of gravity of the first cup body 21 , the cup cover 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 hoisted on the cup cover 25, in order to avoid the excessive weight of the second cup body 22 causing the second cup body 22 to bend the cup cover 25 or the connection between the second cup body 22 and the cup cover 25 to break, the side wall thickness of the second cup body 22 is set to be lower than the side wall thickness of the first cup body 21.

[0091] In some embodiments of the present invention, since the second cup body 22 is in working state, in order to reduce working noise, the second cup body 22 is usually accommodated in the first cup body 21. Therefore, in order to improve the visibility of the second cup body 22 in working state, the first cup body 21 and the second cup body 22 are both made of transparent material to facilitate the observation of the food preparation in the second cup body 22 through the first cup body 21. The transparent material can be glass or food-grade transparent plastic material. The first cup body 21 and the second cup body 22 can be made of the same transparent material, or they can be made of different transparent materials, which will not be repeated here.

[0092] In some embodiments of the present invention, reference Figure 6 , 7The second crushing blade 32 includes a blade shaft 35, a blade disposed on the blade shaft 35, and a spoiler 39 fixed to the outer periphery of the blade shaft 35. The spoiler 39 has a blunt end and extends upward along the rotation direction of the blade shaft 35. During the rotation of the blade shaft 35, the material located in front of the spoiler 39 is pushed forward and downward by the blunt end and the lower surface of the spoiler 39, thereby preventing the material from staying at a certain height, increasing the probability of the material colliding with the cutting edge 361 of the first blade 36, and effectively cutting the material; the material located behind the spoiler 39 falls as the blade shaft 35 rotates, collides with the first blade 36, and is effectively cut. Therefore, under the disturbing effect of the spoiler 39, the material is cut by the first blade 36 in a cycle from top to bottom, and the spoiler 39 can also press the material downward to prevent the material from splashing upward to the cup cover 25, so that the material is fully disturbed in the cup body, increasing the contact probability between the food and the cutting edge 361 of the first blade 36. During the rotation of the blade shaft 35, the first blade 36 cuts the material in a cycle to improve the crushing effect.

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

[0094] Furthermore, the second crushing knife 32 also includes a second blade 37 located above the spoiler 39 , and the first blade 36 , the second blade 37 and the spoiler 39 are staggered along the rotation direction of the knife shaft 35 , and the cutting edge 361 of the second blade 37 is arranged to face one side of the spoiler 39 .

[0095] By arranging the second blade 37 above the spoiler 39, the material above the spoiler 39 can be fully cut. The cutting edge 361 of the second blade 37 is arranged to face one side of the spoiler 39 to prevent the upper material from splashing upward to the cup cover 25 during the cutting process.

[0096] Furthermore, the second crushing blade 32 further includes a third blade 38 located between the spoiler 39 and the first blade 36 , and the third blade 38 extends horizontally outward from the blade shaft 35 .

[0097] Through the third blade 38, the third blade 38 and the first blade 36 can jointly cut the material pressed down by the spoiler 39, thereby increasing the cutting effect of the lower material. The third blade 38 extends horizontally, which can increase the cutting effect of the material between the spoiler 39 and the first blade 36 without affecting the collision of the material with the first blade 36, thereby improving the crushing effect.

[0098] In some embodiments of the present invention, reference Figure 5 , 6The food processor further comprises a fourth cup body 24 detachably mounted on the main machine 1, wherein a fourth crushing knife 34 is disposed in the fourth cup body 24. By providing the fourth cup body 24, the utilization rate of the main machine 1 is further increased, the function of the food processor is expanded, and the application is more extensive.

[0099] Specifically, the first cup body 21 is a grinding cup, and a flip cover 12 is provided on the top of the main machine 1. When the flip cover 12 is opened, the connector 13 on the top of the main machine 1 is exposed to couple with the connector 13 in the cup holder of the grinding cup to realize the transmission of the fourth crushing knife 34. When the flip cover 12 is closed, the connector 13 can be protected. On the one hand, the connector 13 is dustproof in a non-working state; on the other hand, when the first cup body 21, the second cup body 22, or the third cup body 23 is in a working state, the connector 13 is prevented from being exposed and rotating to cause safety risks to users.

[0101] In some embodiments of the present invention, in addition to the need for multiple cups, current users also have different rotational speed requirements for different ingredients. For example, when mincing meat or chopping vegetables, a relatively high rotational speed is required to crush the ingredients, while for kneading noodles or beating eggs, a relatively low rotational speed is required. To this end, the food processor is also provided with a secondary reduction box and two output shaft holes, so that the first crushing knife 31 is in transmission cooperation with the first output shaft hole, and the auxiliary crushing knife is in cooperation with the second output shaft hole, so that the rotational speeds of the two output shaft holes can be inconsistent, which is used to whip specific ingredients, further meeting the user's need for one machine with multiple uses.
