Stirring assembly and food processor

Abstract

This utility model discloses a mixing assembly and a food processor. The mixing assembly includes a power output shaft and a blade assembly. The blade assembly includes at least a blade shaft and mixing blades mounted on the blade shaft. The blade shaft is detachably sleeved on the power output shaft and is drive-connected to it. The power output shaft includes a main body and a flat portion at one end of the main body. The blade shaft has a socket hole and a flat insertion hole communicating with the socket hole. The blade shaft is detachably sleeved on the main body of the power output shaft through the socket hole and fitted onto the flat portion through the flat insertion hole to achieve a drive-connection between the two. Compared with the traditional method of machining the entire power output shaft into a regular polygonal prism structure, this utility model's mixing assembly simplifies the process by machining only the flat portion at one end of the main body. Furthermore, due to the shorter length of the flat portion, the flatness and parallelism of each surface are easier to control during machining, resulting in higher machining precision and lower machining costs.

Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a mixing component and a food processor. Background Technology

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] A food processor is a household appliance that integrates functions such as making soy milk, grinding dry powders, juicing, mincing meat, and shaved ice. It is used to make various food products, including juice, soy milk, jam, dry powders, shaved ice, and minced meat. Existing food processors typically include a cup base, a cup body mounted on the base, and a blending blade assembly housed within the cup body. A power output shaft is inserted through the bottom of the cup body. The blending blade assembly includes a blade shaft and blending blades mounted on the blade shaft, which is then mounted on the power output shaft. Therefore, when the power output shaft is rotated, the blade shaft and blending blades rotate simultaneously, thus blending and pulverizing the food within the cup base.

[0004] To achieve the transmission connection between the cutter shaft and the power output shaft, the power output shaft is typically machined into a regular polygonal prism structure, with a transmission hole matching the shape of this prism inside the cutter shaft. The transmission hole is then fitted onto the polygonal prism structure to achieve the transmission connection between the two. However, using this structure requires machining the entire power output shaft into a regular polygonal prism structure, and the power output shaft is relatively long. Ensuring the flatness and parallelism of each surface during machining places high demands on machining accuracy, resulting in high machining costs. Utility Model Content

[0005] In order to overcome the defects of the prior art, the present invention provides a mixing component and a food processor, which can solve the problems of high processing precision and high cost mentioned in the background art.

[0007] The stirring assembly includes:

[0008] Power take-off shaft;

[0009] A blade assembly, comprising at least a blade shaft and stirring blades disposed on the blade shaft; the blade shaft is detachably sleeved on the power output shaft and is drively connected to the power output shaft.

[0010] The power output shaft includes a main body and a flat portion disposed at one end of the main body. The cutter shaft has a socket hole and a flat insertion hole communicating with the socket hole.

[0011] The cutter shaft is detachably sleeved on the main body of the power output shaft through the sleeve hole, and is fitted onto the flat insertion hole to achieve a transmission connection.

[0012] As an optional implementation, the flat portion is a double flat portion structure or a regular polygonal flat portion structure, and the flat portion socket is adapted to the shape of the flat portion.

[0013] As an optional implementation, the tool assembly further includes a tool shaft cap and an elastic ring, wherein:

[0014] The cutter shaft cap is located at the top of the cutter shaft, and the elastic ring is located between the cutter shaft cap and the cutter shaft; the cutter shaft cap is detachably connected to the cutter shaft and presses and fixes the elastic ring;

[0015] The power output shaft also includes a shaft head disposed on the flat portion, and the blade assembly is fitted onto the outer wall of the shaft head by the elastic ring to achieve limiting and fixing.

[0016] As an optional implementation, the elastic ring is a silicone ring or a retaining ring.

[0017] As an optional implementation, the outer side wall of the top of the cutter shaft is provided with an external thread, the cutter shaft cap is provided with a groove, and the side wall of the groove is provided with an internal thread; the cutter shaft cap is threadedly connected to the external thread on the cutter shaft through the internal thread to achieve a detachable connection.

[0018] As an optional implementation, it further includes a limiting protrusion ring disposed around the outer wall of the cutter shaft and located below the external thread, wherein:

[0019] The elastic ring is located in the groove. When the cutter shaft cap is threadedly connected to the cutter shaft until the bottom of the cutter shaft cap abuts against the limiting protrusion and is limited, the elastic ring is pressed and fixed between the inner top wall of the groove and the top wall of the cutter shaft.

[0020] As an optional implementation, the top wall of the cutter shaft is also provided with a rib, and the bottom of the elastic ring is provided with a groove, the rib being inserted into the groove and pressing the elastic ring.

[0021] As an optional implementation, a mounting convex ring extends downward from the bottom of the cutter shaft, wherein:

[0022] The stirring blade has a mounting hole, and the stirring blade is fitted onto the mounting protrusion through the mounting hole.

[0024] In addition, this utility model also provides a food processor, including a mixing cup, a drive motor, and the above-mentioned mixing assembly, wherein:

[0025] The stirring assembly is disposed inside the stirring cup;

[0026] The bottom of the stirring cup has a through hole, and one end of the power output shaft extends through the through hole;

[0027] The power output shaft is the motor shaft of the drive motor, or the power output shaft is connected to the output end of the drive motor.

[0029] (1) The stirring assembly of this utility model is provided with a flat part at one end of the main body of the power output shaft and a flat insertion hole matching the flat part is opened in the cutter shaft. When the flat part is inserted into the flat insertion hole, the transmission connection between the two can be realized. Compared with the traditional method of machining the entire power output shaft into a regular polygonal prism structure, it is simpler to machine the flat part at only one end of the main body. Moreover, since the length of the flat part is shorter, the flatness and parallelism of each surface are easier to control during machining, resulting in higher machining accuracy and lower machining cost.

[0030] (2) The stirring assembly of this utility model has an elastic ring on its blade assembly, which is used to lock the blade assembly onto the head of the power output shaft for limiting and fixing. This prevents the blade assembly from falling off the power output shaft when food is poured out, making it safer to use. In addition, when the blade assembly needs to be disassembled for cleaning, the user only needs to hold the blade shaft cap or blade shaft on the blade assembly and pull it upwards until the elastic ring is disengaged from the power output shaft. At this point, the blade assembly can be removed from the power output shaft, making the operation convenient.

[0031] (3) The stirring assembly of this utility model has the stirring blade fixed on the mounting convex ring by riveting or welding to form an integral part, thus eliminating the need for additional connecting parts, simplifying the structure, reducing the number of parts, and lowering the cost.

[0041] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0042] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0044] Example 1

[0045] See Figure 1-5This utility model provides a stirring assembly, including a power output shaft 1 and a blade assembly 2 detachably mounted on the power output shaft 1. The blade assembly 2 includes at least a blade shaft 21 and stirring blades 24 disposed on the outer wall of the blade shaft 21. The blade shaft 21 is detachably mounted on the power output shaft 1 and is connected to the power output shaft 1 for transmission. The power output shaft 1 includes a main body 11 and a flat portion 12 disposed at one end of the main body 11. The blade shaft 21 has a bottom-opening socket 211 and a flat insertion hole 212 that communicates with the socket 211 and extends vertically. The blade shaft 21 can be detachably mounted on the main body 11 from top to bottom through the socket 211 and is mounted on the flat portion 12 through the flat insertion hole 212 to achieve a transmission connection.

[0046] Therefore, when the power output shaft 1 is driven to rotate, the blade shaft 21 can be driven to rotate through the snap-fit ​​transmission between the flat insertion hole 212 and the flat part 12, thereby driving the stirring blade 24 to rotate to chop and stir the food.

[0047] In addition, by providing a flat portion 12 at one end of the main body 11 of the power output shaft 1, it is simpler to process the flat portion 12 only at one end of the main body 11 compared to the conventional method of machining the entire power output shaft 1 into a regular polygonal prism structure. Furthermore, since the flat portion 12 is shorter, the flatness and parallelism of each surface are easier to control during processing, resulting in higher processing accuracy and lower processing cost.

[0048] Preferably, the cross-section of the main body 11 of the power output shaft 1 is circular, and the socket 211 is a cylindrical hole that matches it; both sides of the flat part 12 are provided with flat parts to form a double flat part structure, and the flat part insertion hole 212 matches the shape of the double flat part structure.

[0049] Therefore, by machining a double flat structure at one end of the main body 11 to form the flat part 12, the machining is simple and the cost is low, but it is difficult to align during assembly.

[0050] Of course, in other embodiments, the flat portion 12 can also be a regular square flat structure (i.e., a regular square prism structure) or a regular hexagonal flat structure (i.e., a regular hexagonal prism structure). Correspondingly, the flat insertion hole 212 is a matching regular square prism hole or regular hexagonal prism hole. Compared with the double flat structure, its processing is more complicated and the cost is higher, but it is easier to align during assembly, and the assembly is more convenient and efficient.

[0051] Of course, it should be noted that the flat part 12 can also be a regular triangular flat part structure or a regular pentagonal flat part structure; correspondingly, the flat part insertion hole 212 is a matching regular triangular prism hole or a regular pentagonal prism hole, which can also achieve the same technical effect. Here, the number of flat parts in the flat part 12 is not limited.

[0052] Furthermore, the tool assembly 2 also includes a tool shaft cap 22 and an elastic ring 23. The tool shaft cap 22 is located at the top of the tool shaft 21, and the elastic ring 23 is located between the tool shaft cap 22 and the tool shaft 21. The tool shaft cap 22 is detachably connected to the tool shaft 21 and presses and fixes the elastic ring 23. The power output shaft 1 also includes a shaft head 13 disposed on the flat portion 12. The shaft head 13 is disposed through the flat insertion hole 212, and the tool assembly 2 is fitted onto the outer wall of the shaft head 13 by the elastic ring 23 to achieve limiting and fixing.

[0053] Therefore, by setting an elastic ring 23 on the knife assembly 2 and using the elastic ring 23 to fit tightly onto the outer wall of the shaft head 13 to limit and fix the knife assembly 2, it can prevent the knife assembly 2 from falling off the power output shaft 1 when pouring out food, making it safer to use. In addition, when it is necessary to remove the entire knife assembly 2 for cleaning, the user only needs to hold the knife shaft cap 22 or the knife shaft 21 on the knife assembly 2 and pull it upwards until the elastic ring 23 disengages from the power output shaft 1. At this time, the knife assembly 2 can be removed from the power output shaft 1, making it convenient to clean the knife assembly 2.

[0054] Preferably, the elastic ring 23 can be a silicone ring or a retaining ring.

[0055] See Figure 2-3 as well as Figure 5 The outer side wall of the top of the cutter shaft 21 is provided with an external thread 214, and the cutter shaft cap 22 is provided with a groove 221 with a bottom opening. The side wall of the groove 221 is provided with an internal thread 2211. The cutter shaft cap 22 is threadedly connected to the external thread 214 on the cutter shaft 21 through the internal thread 2211 to achieve a detachable connection.

[0056] The elastic ring 23 is disposed in the groove 221. The outer wall of the cutter shaft 21 is also provided with a limiting protrusion 215 located below the external thread 214. When the cutter shaft cap 22 is threadedly connected to the external thread 214 on the cutter shaft 21 through the internal thread 2211, the elastic ring 23 is pressed and fixed between the inner top wall of the groove 221 and the top wall of the cutter shaft 21 until the bottom wall of the cutter shaft cap 22 abuts against the top wall of the limiting protrusion 215 to achieve the limiting.

[0057] More specifically, the top wall of the cutter shaft 21 is also provided with a rib 213, and the bottom of the elastic ring 23 is provided with a groove 231. The rib 213 is inserted into the groove 231 and presses the elastic ring 23. Thus, the abutment between the rib 213 and the groove 231 further improves the firmness of pressing the elastic ring 23 and prevents the elastic ring 23 from shifting.

[0058] Furthermore, the bottom of the cutter shaft 21 extends downwards to form a mounting protrusion 216, and the stirring blade 24 has a mounting hole 241, through which the stirring blade 24 is fitted onto the mounting protrusion 216. Preferably, the stirring blade 24 is fixed to the mounting protrusion 216 by riveting or welding to form a single unit.

[0059] Thus, the stirring blade 24 is fixed to the mounting ring 216 by riveting or welding to form an integral part, thereby eliminating the need for additional connecting parts, simplifying the structure, reducing the number of parts, and lowering costs.

[0060] Example 2

[0061] See Figure 6 This embodiment also provides a food processor, including a mixing cup 3, a drive motor 4, and the mixing assembly described in Embodiment 1 above. The mixing assembly is disposed inside the mixing cup 3. A through hole is provided at the bottom of the mixing cup 3, and the bottom of the power output shaft 1 extends through the through hole. The drive motor 4 is disposed outside the mixing cup 3. Preferably, the power output shaft 1 is the motor output shaft of the drive motor 4.

[0062] Therefore, when the drive motor 4 drives the power output shaft 1 to rotate, it can drive the blade assembly 2 to rotate to stir and chop the food in the mixing cup 3, thereby realizing the cooking of the ingredients.

[0063] Example 3

[0064] See Figure 7 The difference between the food processor in this embodiment and that in Embodiment 2 is that the power output shaft 1 and the output shaft of the drive motor 4 are separately configured. That is, the food processor also includes a connecting sleeve 5, and the power output shaft 1 and the output shaft of the drive motor 4 are connected by the connecting sleeve 5 to achieve a transmission connection.

[0065] Thus, by separating the power output shaft 1 from the output shaft of the drive motor 4, the mixing cup 3 and the cup holder 6 can be separated, making it easier to disassemble and clean the mixing cup 3.

[0066] In summary, the mixing component and food processor of this invention have the following beneficial effects:

[0067] (i) The stirring assembly of this utility model provides a flat part 12 at one end of the main body 11 of the power output shaft 1 and opens a flat insertion hole 212 in the cutter shaft 21 that matches the flat part 12. When the flat part 12 is inserted into the flat insertion hole 212, the transmission connection between the two can be realized. Compared with the traditional method of machining the main body 11 into a polygonal prism, it is simpler to machine the flat part 12 at one end of the main body 11. Moreover, since the flat part 12 is shorter, the flatness and parallelism of each surface are easier to control during machining, resulting in higher machining accuracy and lower machining cost.

[0068] (II) The stirring assembly of this utility model has a blade assembly 2 equipped with an elastic ring 23, which is tightly fitted onto the shaft head 13 of the power output shaft 1 for limiting and fixing. This not only prevents the blade assembly 2 from disengaging from the power output shaft 1 when rotating, but also prevents the blade assembly 2 from falling off the power output shaft 1 when pouring out food, making it safer to use. In addition, when it is necessary to disassemble the blade assembly 2 as a whole for cleaning, the user only needs to hold the blade shaft cap 22 or the blade shaft 21 on the blade assembly 2 and pull it upwards until the elastic ring 23 disengages from the power output shaft 1. At this time, the blade assembly 2 can be removed from the power output shaft 1, which is convenient to operate.

[0069] (iii) The stirring assembly of this utility model, wherein the stirring blade 24 is fixed to the mounting protrusion ring 216 by riveting or welding to form an integral part, thereby eliminating the need for additional connecting parts, simplifying the structure, reducing the number of parts, and lowering the cost.

[0070] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

[0071] It should be understood that the terms "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0072] Furthermore, in the description of this utility model, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
