[0002] This application claims priority to Chinese Patent Application No. 2023110188567 entitled “Food Chopper”, filed on August 11, 2023, the disclosure of which is considered to be part of the disclosure of this application, and is hereby incorporated herein by reference in whole or in part. Technical Field

[0003] This utility model belongs to the field of food processing electrical appliances, specifically relating to food choppers, and more particularly to a food chopper that achieves meat grinding function by configuring a second processing component, as well as a processing sub-component. Background Technology

[0004] A food processor is an appliance that uses a motor to drive blades to rotate at high speed to chop food. Some manufacturers also call it a high-speed blender. It is generally equipped with a heating element, such as a heating plate located at the bottom of the container. Food processing is achieved through the heating element and the blade's chopping function. Generally speaking, existing food processors use high speed to chop food. Because the blades of food processors are relatively low, it is usually necessary to add a fluid such as water to chop the food materials.

[0005] Food processors are generally unsuitable for tasks like mincing meat, chopping seasonings, and making fillings into small pieces. Firstly, because the blades are low and the rotation speed is high, and since fluid cannot be added, they can only chop food at the bottom. Although the amount of food fed in at one time can be controlled, the efficiency is low, and the processed food is often too finely chopped, failing to meet requirements. Secondly, they are difficult to clean, easily leading to odors and hygiene problems. People need to purchase a meat grinder for these tasks. Meat grinders have a lower output speed than food choppers, but higher torque. Their blades are usually multi-layered, allowing them to process more food at once, and the blades are detachable for easy cleaning.

[0006] For the reasons mentioned above, people need to purchase multiple devices, which is costly and takes up a lot of space. Summary of the Invention

[0007] The purpose of this invention is to solve the problem that the existing technology requires the purchase of multiple devices for food preparation and chopping into larger particles or non-fluid processing, which is costly and space-consuming. The solution is to design a second food preparation component that can be selectively installed and coupled with the drive mechanism to achieve non-fluid cutting processing.

[0008] One aspect of this application provides a food chopper, comprising: a first cooking assembly and a second cooking assembly; the first cooking assembly includes: a first cup assembly having a first cooking cavity with a first upper opening; a drive mechanism; a first blade disposed at the bottom of the first cooking cavity and drively coupled to the drive mechanism; the second cooking assembly is detachably assembled into the first cooking cavity; and includes: a second cup assembly having a second cooking cavity with a second upper opening; a second blade disposed in the second cooking cavity; and a reduction device including a reduction mechanism, a second input end, and a second output end, the second input end being at least indirectly driveably coupled to the drive mechanism, and the second blade being drively coupled to the second output end.

[0009] This food chopper can process food using a first processing component. When it is necessary to chop ingredients into larger particles or for non-fluid processing, a second processing component is assembled into the first processing chamber, and the second input end is coupled to the drive mechanism. Because the second processing component is equipped with a reduction gear, the torque of the second blade can be increased to meet the needs of food chopping. Furthermore, the second blade can be configured with multiple layers as needed, allowing for the simultaneous cutting of more food. One device can achieve two processing methods, saving costs. Since the second processing component and the first processing chamber are detachable, disassembly and cleaning are convenient. When storing, the second processing component can be placed inside the first processing chamber, occupying little space and facilitating placement.

[0010] Furthermore, the second cutter is detachably connected to the second output end. This configuration makes cleaning easier.

[0011] Furthermore, the upper end of the first tool is equipped with a transmission unit, and the second input end is coupled to the transmission unit. This design allows for coupling with the second input end without disassembling the first tool, making it convenient and quick to use.

[0012] As an alternative, the first tool can be disassembled and the second input end can be coupled to the output end of the drive mechanism.

[0013] Furthermore, it also includes a first cover for opening and closing the first upper opening of the first cooking cavity, the first cover covering the second upper opening of the second cup assembly, and the first cover having a positioning structure that rotatably engages with the upper end of the second blade. This allows the second blade to remain stable during operation. In another embodiment, a second cover is provided, used for opening and closing the second upper opening of the second cup assembly, and the second cover having a positioning structure that rotatably engages with the upper end of the second blade. The second cover better fits the second cup assembly, and after the second cup assembly is removed from the first cooking cavity, it can close the opening of the second cooking cavity, providing a protective cover.

[0014] Furthermore, the second cooking component also includes a second cup holder, a deceleration device disposed within the second cup holder, and a second cup body assembly connected to the upper side of the second cup holder. By placing the deceleration device within the second cup holder, the structure of the second cooking component can be made more compact.

[0015] Furthermore, the lower end of the second cooking component is provided with one or more support parts, and the second cooking component is mounted above the bottom wall of the first cooking cavity via one or more support parts. This design ensures stable support for the second cooking component, allowing it to be placed on a flat surface after being removed from the first cooking cavity via the one or more support parts.

[0016] Furthermore, the one or more support portions are provided with cushioning material that contacts the bottom wall of the first cooking cavity. With this design, during operation, the cushioning material can reduce vibration between the first cooking component and the first cooking cavity, while also reducing noise.

[0017] This application also provides a food preparation sub-assembly for detachably coupling with the drive mechanism of a food processor to achieve food chopping. The food preparation sub-assembly includes: a sub-cup body, a sub-blade, and a reduction gear; the sub-cup body has a sub-cooking cavity with a second upper opening, and the sub-blade is disposed in the sub-cooking cavity; the reduction gear is disposed on the lower side of the bottom of the sub-cooking cavity and includes a reduction mechanism, the input end of the reduction mechanism being detachably coupled to the drive mechanism at least indirectly, and the output end of the reduction mechanism being drively connected to the sub-blade.

[0018] The food processing sub-component of this application can be selectively assembled into the food processor and detachably coupled to the drive mechanism when it is necessary to chop ingredients into larger particles. Because the sub-component is equipped with a speed reduction device, the torque of the sub-blades can be increased to meet the needs of food chopping. Furthermore, the sub-blades can be configured with multiple layers as needed, allowing for the simultaneous cutting of more food. One device can perform two processing methods, saving costs. The detachable assembly of the food processing sub-component also facilitates disassembly and cleaning.

[0019] Furthermore, it also includes a sub-cup holder, which is connected to the lower side of the sub-cup body. The deceleration device is disposed inside the sub-cup holder, and the input end is located in the lower middle part of the sub-cup holder. One or more support parts are provided at the lower end of the sub-cup holder, and the sub-cooking component passes through one or more support parts. Attached Figure Description

[0041] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0042] See Figures 1 to 4 This utility model generally relates to a food chopper and a second cooking component (cooking sub-component b). The coupling described in this utility model is a connection that enables rotary transmission, such as the second input end 5.1 of the reduction mechanism 50 being detachably coupled to the drive mechanism 3. That is, the second input end 5.1 and the output end 3.1 of the drive mechanism 3 are detachably and circumferentially positioned connected, such as a square shaft and a square hole, or a polygonal shaft and a polygonal hole, or a plum blossom hole and a shaft, or a transmission coupling structure existing in the art.

[0043] The second blade k2 is a blade capable of chopping ingredients into larger particles, such as mincing meat. It typically requires multiple blades, such as two or more layers. Of course, the number of blades can be adjusted according to actual needs; in some embodiments, it can be a single layer. Furthermore, regarding the use of the second cooking component (cooking sub-component) b, the scope of protection of this application is not limited to mincing meat, but can also include other uses that require processing separately from the first cooking component a. For example… Figure 10 As shown, the second cutting tool k2 includes a tool body k2' and a cutting blade k2.1' disposed on the tool body k2'. Figure 10 An embodiment with two layers of blades k2.1' is shown; in other embodiments, one, three, or more layers may be configured. The assembly of the blades k2.1' and the body k2' can be achieved by injection molding the body k2' separately and then assembling it with the blades k2.1', such as using interference fits or threaded connections commonly used in the art. Alternatively, the blades k2.1' can be injection molded and fixed to the body k2. Of course, it can also be achieved using structures found in shredders, such as meat grinders, in the art.

[0044] See Figures 1 to 8In some embodiments, the food chopper includes: a first cooking component a and a second cooking component b; the first cooking component a includes: a first cup assembly 1 having a first cooking cavity 100 with a first upper opening 10; a first cover 2 for opening and closing the first upper opening 10 of the first cooking cavity 100; a drive mechanism 3 disposed below the first cup assembly 1 and including a drive motor; a first blade k1 disposed at the bottom of the first cooking cavity 100 and drivenly coupled to the drive mechanism 3; the second cooking component b is detachably assembled into the first cooking cavity 100 and includes: a second cup assembly 4 having a second cooking cavity 400 with a second upper opening 40; a second blade k2 disposed in the second cooking cavity 400; a reduction device 5 disposed below the second cup assembly 4, including a reduction mechanism 50, a second input end 5.1 and a second output end 5.2, the second input end 5.1 being detachably drivenly coupled to at least the drive mechanism 3, and the second blade k1 being drivenly coupled to the second output end 5.2.

[0045] The reduction mechanism 50 of this application can be a gear reduction mechanism, such as achieving reduction through one or more sets of gears with different transmission ratios. It can include a combination of double gears and single gears, a combination of multiple double gears, or a combination of multiple single gears; or it can achieve reduction through a planetary reduction mechanism. Such a reduction mechanism can be implemented based on currently known reduction mechanisms.

[0046] The food chopper of this application can process food through the first processing component a. When it is necessary to chop the ingredients into larger particles, the second processing component b is assembled into the first processing chamber 100, so that the second input end 5.1 is coupled with the drive mechanism 3. Since the second processing component b is equipped with a reduction device 5, the torque of the second blade k2 can be increased to meet the needs of chopping food. Moreover, the second blade k2 can be configured with multiple layers, which can cut more food at the same time. One device can realize two processing methods, saving costs.

[0047] Because the second cooking component b is detachable from the first cooking cavity 100, it is easy to disassemble and clean. When storing, the second cooking component b can also be placed inside the first cooking cavity 100, taking up little space and making it convenient to place. Furthermore, the configuration of the second cooking component b allows for separate processing of food; food processed in the second cooking component b will not affect the first cooking cavity 100. For example, raw meat can be processed in the second cooking component b, separately from the first cooking component a, making it more hygienic and healthier.

[0048] See Figure 5 and Figure 6In one embodiment, the second tool k1 is detachably connected to the second output end 5.2. This configuration facilitates cleaning. The second tool k1 and the second output end 5.2 can be coupled using a connector and socket transmission coupling method. For example, the second tool k1 can be equipped with a protruding connector, and the second output end 5.2 can be equipped with an interface. A structure restricting relative rotation can be configured between the connector and the interface, such as a quincunx structure, a square structure, a flat structure, etc., or other known structures for detachable connection between the tool and the transmission output. Of course, a threaded connection structure is also possible.

[0049] See Figure 2 , Figure 5 and Figure 6 In one embodiment, the upper end of the first cutting tool k1 is provided with a transmission part k1.1, and the second input end 5.1 is coupled to the transmission part k1.1. With this structure, the second cutting tool k2 can be directly coupled to the transmission part k1.1 without disassembling the first cutting tool k1, making it convenient and quick to use.

[0050] In other embodiments, a tool-changing method is used, that is, after the first tool k1 is disassembled, the second input end 5.1 is coupled to the output end 3.1 of the drive mechanism 3. The method of transmission coupling can refer to the method in which the second tool k1 is detachably connected to the second output end 5.2.

[0051] See Figure 5 In one embodiment, the first cover 2 is provided with a positioning structure that rotatably engages with the upper end of the second cutter k2. This ensures the stability of the second cutter k2 during operation. Using the first cover 2 to position the upper end of the second cutter k2 results in a simple structure, convenient use, and easy cleaning.

[0052] Specifically, the first cover 2 is provided with a first engagement portion 201 that engages with the first upper opening 10 of the first cooking cavity 100, and a second engagement portion 202 that engages with the second upper opening 40 of the second cooking cavity 400. Through the above improvements, by using the first cover 2 to cover the first upper opening 10 of the first cooking cavity 100 and the second upper opening 40 of the second cooking cavity 400, it is possible to prevent food from being thrown out during processing in the second cooking cavity 100.

[0053] In one embodiment, the first joint 201 and the second joint 202 may be made of a soft material, such as silicone or other materials known in the art. Since the size of the second cooking component b is smaller than the size of the first cooking cavity 100, the size of the second cooking cavity 400 is smaller than the size of the first cooking cavity 100. Therefore, the size of the first joint 201 is at least partially (the sealing or joining portion) larger than the size of the second joint 202 (the sealing or joining portion).

[0054] The first joint 201 and the second joint 202 can also be formed on a single component, such as a flexible sleeve-shaped component. One or more first joint pieces are formed on the outer surface of the sleeve-shaped component to form the first joint, and one or more second joint pieces are formed below the first joint to form the second joint. The size of the first joint piece is larger than the first upper opening 10 of the first cooking cavity 100, and the size of the second joint piece is larger than the second upper opening 40 of the second cooking cavity 400. Because the first and second joints are sheet-like, they have good elastic deformation, which ensures that the first cover 2 can easily and conveniently cover the upper end of the first cooking cavity 100 and / or the upper end of the second cooking cavity 400. Of course, normally, the first joint fits tightly with the first upper opening 10 of the first cooking cavity 100 to ensure that liquid food processed in the first cooking cavity 100 does not splash out; the second joint can also fit tightly with the second cooking cavity 400.

[0055] In other embodiments, the first joint and the second joint may be two components, such as those made of flexible materials, which are then installed onto the first cover 2.

[0056] Positioning structure such as Figure 5 As shown, a rotating shaft protrusion k2.1 can be configured on the upper end of the second tool k2, and a rotating positioning hole 2.1 that mates with the shaft protrusion k2.1 can be configured on the first cover 2. The rotating shaft protrusion k2.1 can be rotatably mounted into the rotating positioning hole 2.1. Of course, the rotating shaft protrusion k2.1 and the rotating positioning hole 2.1 can be interchanged, such as... Figure 21 As shown, a rotating shaft protrusion is constructed on the first cover body 2, and a rotating positioning hole 2.1 is constructed on the upper end of the second cutter k2.

[0057] See Figure 20 In another embodiment, a second cover 2' is provided. The second cover 2' is used to open and close the second upper opening 40 of the second cooking cavity 400. The second cover 2' has a positioning structure that rotatably engages with the upper end of the second blade k2. The second cover 2' better fits the second cup assembly b. After the second cup assembly b is removed from the first cooking cavity 100, it can close the opening of the second cooking cavity 100, providing protection and preventing food in the second cooking cavity 400 from contacting the first cooking cavity 100, thus providing a hygienic barrier. For example, if the second cooking cavity 400 is used for mincing meat, the second cover 2' can prevent it from falling into the first cooking cavity 100.

[0058] As mentioned above, the positioning structure can be configured with a rotating shaft protrusion k2.1 on the upper end of the second tool k2, and a rotary positioning device that mates with the shaft protrusion k2.1 on the second cover 2. The rotating shaft protrusion k2.1 can be rotatably fitted into the rotary positioning hole. Of course, it can also be as follows: Figure 21As shown, the upper end of the second tool k2 is provided with a rotary positioning hole k2.1, and the second cover 2' is provided with a rotary shaft protrusion 2.1' that cooperates with the rotary positioning hole k2.1.

[0059] In other embodiments (not shown), a second cover is provided, which is used to open and close the second upper opening 40 of the second cup assembly 4. The second cover is constructed with a clearance hole to avoid the upper end of the second cutter k2. A rotational positioning structure is constructed between the upper end of the second cutter k2 and the first cover 2. The positioning structure can adopt the structure of other embodiments of this application.

[0060] See Figures 1 to 8 In one embodiment, the first cooking component a includes a first cup body component 1 and a first cup holder 1', and the drive mechanism 3 is mounted on the first cup holder 1'.

[0061] like Figures 1 to 8 In the illustrated embodiment, a base c' is also provided, which has a cavity c0' for positioning the lower part of the first cooking component a, a circuit module c.1' electrically coupled to the first cooking component a, and a heat dissipation mechanism c.2. The specific structure of the base c' is not an improvement of this application.

[0062] See Figure 9 As shown, the first cooking component a includes only the first cup body component 1 and the first cup holder area 1', and the drive mechanism 3 is installed in the first cup holder area 1'.

[0063] Alternatively, in other embodiments, the first cooking component a and the drive mechanism 3 may be encapsulated in a single housing.

[0064] See Figures 10 to 15 In one embodiment, the second cooking component b further includes a second cup holder 6, a speed reduction device 5 disposed within the second cup holder 6, and a second cup body component 4 connected to the upper side of the second cup holder 6. Distributing the speed reduction device within the second cup holder 6 allows for a more compact structure in the second cooking component b.

[0065] See Figure 12 and Figure 14 In one embodiment, the second cup holder 6 includes a second cup holder body 601 having a side wall 6011 and a top wall 6012, and a second cup holder cover 602 having a side wall 621' and a bottom wall 6022'. A speed reduction device 5 is installed on the second cup holder cover 602. Specifically, the speed reduction device 5 is installed on the drive mounting part 6022 of the second cup holder body 601. The second cup holder cover 602 is connected to the inside of the second cup holder body 601 through a connecting hole 6021. The bottom wall 6022' is constructed to avoid the second input end 5.1.

[0066] See Figures 13 to 15In one embodiment, the second cup body assembly 4 is detachably connected to the second cup holder 6. This design facilitates the disassembly of the second cup body assembly 4 for cleaning.

[0067] See Figures 13 to 15 In one embodiment, the second cup assembly 4 includes a second cup body 4.1 and a bottom wall 4.2. The transmission hole 401 is constructed in the middle of the bottom wall 4.2. The second cup body 4.1 and the bottom wall 4.2 can be manufactured by an integral molding process, such as injection molding of PC or PP materials; or by glass; of course, they can also be manufactured by current processes such as stamping and welding of metal materials.

[0068] See Figures 13 to 15 In one embodiment, a cylinder 402 extends upward from the edge of the transmission hole 401 on the bottom wall 4.2. The second cutter k2 is provided with an assembly space k20 for fitting the cylinder 402, and a second cutter transmission joint k2.2 is at least indirectly coupled to the drive mechanism 3 through the cylinder 402. Since the second cutter k2 is detachable, the arrangement of the cylinder 402 and the assembly space k20 prevents residual material or fluid from falling into the transmission hole 401 when disassembling the second cup assembly 4; it also prevents food from entering the transmission hole 401 during processing, thereby facilitating the cleaning of the second cup assembly 4.

[0069] See Figure 10 , Figure 13 and Figure 14 The lower part of the transmission hole 401 has a sealing part 4011 with an increased diameter. The second output end 5.2 protrudes from the top wall 6012 of the second cup seat body 601, and a sealing ring s is disposed between the second output end 5.2 protrusion and the sealing part 4011. By adopting the above solution, the transmission hole 401 and the sealing part 4011 can be effectively sealed. In order to facilitate manufacturing, the transmission hole 401 extends downward to form a sealing wall, and the sealing part 4011 is formed on the inner side of the sealing wall.

[0070] See Figures 13 to 15 One connection scheme between the second cup body assembly 4 and the second cup seat 6 is a screw-on structure 46, wherein the lower end of the second cup body assembly 4 is provided with a plurality of upper screw-on portions 46.1, and the upper end 601 of the second cup seat 6 is provided with a plurality of lower screw-on portions 46.2. The second cup body assembly 4 and the second cup seat 6 rotate relative to each other. When the upper screw-on portions 46.1 and the lower screw-on portions 46.1 are aligned, the two are fixedly connected. When the upper screw-on portions 46.1 and the lower screw-on portions 46.1 are disengaged when the second cup body assembly 4 and the second cup seat 6 rotate relative to each other, the two can be disassembled.

[0071] In one embodiment, the upper screw-in portion 46.1 and the lower screw-in portion 46.1 are staggered protrusions, see [reference]. Figures 13 to 15As shown, both the upper screw-in portion 46.1 and the lower screw-in portion 46.1 are protrusions. A screw-in channel 460 with an opening on the screw-in side is formed on the lower side of the lower screw-in portion 46.1. The upper screw-in portion 46.1 is screwed into the screw-in channel 460 and confined to the lower side of the lower screw-in portion 46.1. To facilitate the screwing of the upper screw-in portion 46.1 into the screw-in channel 460, the top wall of the screw-in side of the screw-in channel 460 is constructed with a beveled portion.

[0072] In other embodiments, one of the screw-on portions can be a rotating protrusion, and the other can be provided with a retaining groove. Rotation engages the upper screw-on portion 46.1 and the lower screw-on portion 46.1 to achieve connection and fixation, while reverse rotation achieves disassembly. For example, the upper screw-on portion 46.1 is a rotating protrusion, and the lower screw-on portion 46.2 is a retaining groove. Figure 9 and Figure 10 As shown, the upper end of the second cup holder 6 is provided with a lower joint edge 6.3, and the lower end of the second cup body assembly 4 is provided with an upper joint edge 4.3. The sides of the lower joint edge 6.3 and the upper joint edge 4.3 that fit together are respectively provided with the upper screw joint 46.1 and the lower screw joint 46.2.

[0073] like Figure 9 and Figure 10 In one embodiment shown, the upper connecting edge 4.3 engages the outer side of the lower connecting edge 6.3. A plurality of upper screw-in portions 46.1 are spaced apart and disposed on the inner side of the upper connecting edge 4.3, and a plurality of lower screw-in portions 46.2 are spaced apart and disposed on the outer side of the lower connecting edge 6.3. When the upper connecting edge 4.3 engages the lower connecting edge 6.3, rotation can cause the upper screw-in portion 46.1 to engage the lower side of the lower screw-in portion 46.2, thereby fixing the second cup body assembly 4 and the second cup seat 6. When rotation causes the upper screw-in portion 46.1 to disengage from the lower screw-in portion 46.2, the second cup body assembly 4 can be detached from the second cup seat 6.

[0074] Specifically, the lower screw-in part 46.2 has a slot (screw-locking channel 460) with the same screw-side opening on the lower side. With this configuration, the second cup body assembly 4 can only be connected to the second cup seat 6 from one screw direction, ensuring that the rotational connection is in place; when disassembling, rotate in the opposite direction to disengage the upper screw-in part 46.1 and the lower screw-in part 46.2.

[0075] See Figure 15To ensure the reliable connection between the second cup assembly 4 and the second cup holder 6, an anti-detachment structure is provided between the upper screw-in portion 46.1 and the lower screw-in portion 46.2. Specifically, one screw-in portion 46.1 is provided with one or more protrusions 46.20, and the other screw-in portion is provided with one or more recesses 46.10. When the upper screw-in portion 46.1 and the lower screw-in portion 46.2 are connected, the protrusions 46.20 and the recesses 46.10 engage. During installation and disassembly, the user needs to apply a certain amount of rotation to assemble or disassemble the second cup assembly 4 and the second cup holder 6, thus ensuring that the second cup assembly 4 and the second cup holder 6 do not become loose during use. For example, a recess 46.10 is constructed in the upper screw-in part 46.1, and a protrusion 46.20 is constructed in the inner wall of the screw-lock channel 460. When the upper screw-in part 46.1 is screwed into the screw-lock channel 460, the recess 46.10 is locked into the protrusion 46.20, which can effectively prevent the connection between the second cup body assembly 4 and the second cup seat 6 from becoming loose.

[0076] like Figure 15 As shown, the protrusion 46.10 is disposed on the inner wall of the lower screw-in portion 46.2 (slot), and the recess 46.10 is disposed on the outer edge of the upper screw-in portion 46.1. Of course, the protrusion 46.20 and the recess 46.10 are not limited to the above positions, and can be disposed in other positions of the lower screw-in portion 46.2 and the upper screw-in portion 46.1 as needed.

[0077] In other embodiments, the mating edge 4.3 may also be designed to fit the inner side of the lower mating edge 6.3, in which case the upper screw-on portion 46.1 is located on the outer side of the upper mating edge 4.3, and the lower screw-on portion 46.2 is located on the inner side of the lower mating edge 6.3.

[0078] In other embodiments, the upper screw-in portion 46.1 is a slot.

[0079] In other embodiments, the second cup body assembly 4 and the second cup seat 6 are connected by a threaded structure.

[0080] See Figure 10 and Figure 18 The inner wall of the second cup body 4.1 of this application has one or more flow-dispersing ribs b01'. The flow-dispersing ribs b01' are preferably vertically extending and spaced apart. (See attached...) Figure 10 In the illustrated embodiment, the baffle rib b01' is formed by protruding inward from the sidewall of the second cup body 4.1. Specifically, when the second cup body 4.1 is made of plastic or glass, the baffle rib b01' is integrally manufactured with the second cup body 4.1; when the second cup body 4.1 is made of metal, the baffle rib b01' is formed by stamping. To facilitate observation of the processing status of the second cooking cavity 400, the second cup body 4.1 is preferably made of a transparent material, such as transparent plastic or glass; it is readily understood that these materials are well-known.

[0081] See Figures 16 to 19 In another embodiment of the second cooking component b of this application, the second cooking component b includes a second cup body assembly 4 and a second cup holder 6. The second cup body assembly 4 includes a second cup body 4.1 and a base 4.2. The second cup body 4.1 has an upper port and a lower port. The base 4.2 is sealed to the lower end of the second cup body 4.1 by a sealing ring 4.3. The second cup holder 6 is connected to the lower side of the base 4.2. The deceleration device 5 is disposed in the second cup holder 6. As can be seen from the foregoing, disposing of the deceleration device 5 in the second cup holder 6 can make the structure of the second cooking component b more compact.

[0082] See Figure 12 , Figure 14 , Figures 16 to 19 In one embodiment, the second cup holder 6 includes a second cup holder body 601 having a side wall 6011 and a top wall 6012, and a second cup holder cover 602 having a side wall 621' and a bottom wall 6022'. A speed reduction device 5 is installed on the second cup holder cover 602. Specifically, the speed reduction device 5 is installed on the drive mounting part 6022 of the second cup holder body 601. The second cup holder cover 602 is connected to the inside of the second cup holder body 601 through a connecting hole 6021. The bottom wall 6022' is constructed to avoid the second input end 5.1.

[0083] One specific connection method between the second cup holder 6 and the second cup body assembly 4 is shown in [reference]. Figures 16 to 19 The lower end of the second cup body 4.1 has an inwardly extending lower connecting part 4.10. The sealing ring 4.3 has a sealing assembly groove that communicates with the outside. The sealing ring 4.3 is fitted onto the lower connecting part 4.10 through the sealing assembly groove. The edge of the base plate 4.2 extends to the lower connecting part 4.10 to cover the upper side of the sealing ring 4.3. The second cup seat 6 is connected to the base plate 4.2 by a connector such as a screw to tighten the base plate 4.2, so that the base plate 4.2 and the connecting part 4.10 squeeze the sealing ring 4.3 to achieve a seal.

[0084] Specifically, the top wall 6012 of the second cup holder 6 has a connecting hole 60120, through which screws are directly or indirectly connected to the chassis 4.2 (if other intermediate connectors are configured).

[0085] In addition to the screw connection mentioned above, the second cup body 4.1 and the second cup seat 6 can also be made of engineering plastics and connected by ultrasonic welding, known adhesive materials, etc.

[0086] The chassis 4.2 is made of materials with high structural strength, such as metals (stainless steel, aluminum alloy, etc.), or it can be a known plastic material that meets the requirements of structural strength.

[0087] A plurality of positioning protrusions b012' are constructed along the edge of the top wall 6012 of the second cup seat 6. The outer wall of the second cup body 4.1 is recessed to form a groove structure b011' that connects to its lower end, corresponding to the position of one or more bleed ribs b01'. The positioning protrusions b012' are embedded in the groove structure b011'. Through the above structure, the circumferential force of the second cup body assembly 4 and the second cup seat 6 can be applied between the positioning protrusions b012' and the groove structure b011', thereby reducing the force on the vertical connection (such as screw connection) between the second cup body assembly 4 and the second cup seat 6, making its structure more stable and reliable.

[0088] As described above, when the second cup body 4.1 is made of plastic or glass, the baffle rib b01' is integrally manufactured with the second cup body 4.1; when the second cup body 4.1 is made of metal, the baffle rib b01' is formed by stamping.

[0089] See Figure 2 and Figure 11 In one embodiment, the inner wall of the first cooking cavity 100 is provided with a plurality of vertically spaced positioning protrusions a01, and the side of the second cooking component b is provided with a plurality of spaced positioning grooves b01. When the second cooking component b is installed into the first cooking cavity 100, the positioning protrusions a01 are inserted into the positioning grooves b01, thereby restricting the rotation of the second cooking component b. Using the above solution, the rotation of the second cooking component b due to the reaction force of the food during operation can be restricted. Moreover, the structure is simple and assembly is convenient. Another function of the positioning protrusions a01 is to turbulence, improving the food processing effect. Therefore, in some embodiments, the positioning protrusions a01 can directly utilize the existing turbulence ribs on the inner wall of the first cooking cavity 100 without additional design and processing, reducing production costs.

[0090] In some embodiments, the positioning groove b01 is formed at least in one of the second cup body assembly 4 and the second cup seat 6. A specific preferred embodiment is shown below. Figure 3 , Figure 11 , Figure 12 , Figure 15 , Figure 16 and Figure 19 As shown, the positioning groove b01 is preferably constructed on the second cup body assembly 4 and the second cup seat 6, that is, the positioning groove b01 of each part of the second cup body assembly 4 and the second cup seat 6 corresponds vertically and is connected to the lower end of the second cup seat 6. This structure facilitates the installation of the second cooking component b from the first cooking cavity 100 from top to bottom, and makes the positioning groove b01 cooperate with the positioning protrusion a01.

[0091] like Figure 3 , Figure 11 , Figure 12 , Figure 15 , Figure 16 and Figure 19 In the embodiment shown, the positioning protrusion a01 is located in the positioning groove b01 of both the second cup body assembly 4 and the second cup seat 6. This structure allows the circumferential force on the second cooking component b to be transmitted from both the second cup body assembly 4 and the second cup seat 6 to the positioning protrusion a01, optimizing the force on the second cooking component b and preventing either the second cup body assembly 4 or the second cup seat 6 from being subjected to excessive force, which could cause unstable fit or damage.

[0092] Of course, in some other embodiments, the positioning groove b01 is only constructed on the second cup body assembly 4. In this case, a corresponding avoidance structure needs to be set on the second cup seat 6, such as designing a recess or avoidance plane at the part of the second cup seat 6 corresponding to the positioning groove b01, or directly designing the side dimension of the second cup seat 6 to be smaller than the inner side of the positioning groove b01.

[0093] In other embodiments, the positioning groove b01 is constructed only on the second cup holder 6.

[0094] The design schemes of the two positioning grooves b01 mentioned above can meet the positioning requirements by optimizing the structure of the second cup body component 4 or the second cup seat 6, such as material selection, thickness selection, and adding reinforcing structures.

[0095] like Figure 3 , Figure 11 , Figure 12 , Figure 15 , Figure 16 and Figure 19 In the embodiment shown, the positioning groove b01 on the second cup assembly 4 is formed by the recessed position of the bleed rib b01' corresponding to the outer wall of the second cup 4.1.

[0096] See Figure 5 , Figure 11 and Figure 12 In one embodiment, the lower end of the second cooking component b is provided with one or more support portions b02, and the second cooking component b is mounted above the bottom wall of the first cooking cavity 100 via the one or more support portions b02. This design ensures stable support for the second cooking component b. Furthermore, during operation, the buffer reduces vibration between the first cooking component and the first cooking cavity, while also reducing noise. (See also...) Figure 5 , Figure 11 and Figure 12 In the illustrated embodiment, four support portions b02 are provided. In other embodiments, the support portions b02 may be provided in smaller quantities, such as two or three, or in more quantities, such as five or more.

[0097] See figure. Figure 5 , Figures 11 to 14As shown, a clearance space b0 is constructed between the inner side of the support b02 and the bottom of the second cup holder 6. When the second cooking component b is installed into the first cooking cavity 100 and the second input end 5.1 is coupled with the transmission part k1.1 of the first cutter k1, the clearance space b0 can avoid the first cutter k1.

[0098] When multiple support parts b02 are used, an exhaust channel b03 is formed between adjacent support parts b02, which can exhaust the airflow generated when the first cutter k1 is working, parallel to the air pressure at the bottom of the second cooking component b.

[0099] Of course, the discharge channel b03 can also be in other forms, such as the bottom of the second cup seat 6 having a clearance space b0, the lower end of the wall of the second cup seat 6 serving as a support, and the lower end of the second cup seat 6 having a discharge channel b03 connecting the clearance space b0, such as a hole structure or a groove structure.

[0100] See Figure 11 and Figure 12 In one embodiment, the one or more support portions b02 are provided with a buffer member b.1 that contacts the bottom wall of the first cooking cavity 100. Specifically, the one or more support portions b02 are provided with a connecting portion, and the buffer member b.1 is connected to the connecting portion, such as by screws, or the one or more support portions b02 are provided with mounting holes, and the buffer member b.1 is inserted into the mounting holes; or, the buffer member b.1 is connected to the one or more support portions b02 by an adhesive. The buffer member b.1 is preferably flexible, such as silicone material, but other known flexible materials can also be used. The buffer member b.1 can reduce collisions with the bottom wall of the first cooking cavity 100, preventing or reducing noise generation; on the other hand, when the second cooking component b is removed and placed in another position (such as on a countertop), the buffer member b.1 serves as an anti-slip element.

[0101] In some embodiments, in order to facilitate the taking and putting away of the second cooking component b, a handle (not shown) that can be flipped over and stored is provided on the upper side of the second cooking component b.

[0102] See Figures 11 to 15 The technical solution of the second cooking component b is described below: The second cooking component b includes: a second cup assembly 4, a second cooking cavity 400 having a second upper opening 40; a second knife k2, disposed in the second cooking cavity 400; and a speed reduction device 5, disposed on the lower side of the second cup assembly 4, including a speed reduction mechanism 50, a second input end 5.1 and a second output end 5.2, wherein the second knife k1 is drivenly coupled to the second output end 5.2.

[0103] In one embodiment, the second tool k1 is detachably connected to the second output terminal 5.2. This configuration makes cleaning easier.

[0104] In one embodiment, the second cooking component b further includes a second cup holder 6, a deceleration device 5 is disposed within the second cup holder 6, and a second cup body component 4 is connected to the upper side of the second cup holder 6.

[0105] In one embodiment, the second cup assembly 4 and the second cup holder 6 are detachably connected. This design makes cleaning the second cup assembly and the second cup holder easier after disassembly. In another embodiment, an upwardly extending cylinder 402 is provided on the upper side of the upper edge of the transmission hole 401 in the middle of the bottom wall of the second cup assembly 4. The second tool k2 has an assembly space k20 for fitting the cylinder 402, and a tool transmission joint k2.1 coupled to the drive mechanism 3 through the cylinder 402. The cylinder 402 prevents residual material or fluid from falling out when disassembling the second cup assembly 4.

[0106] One solution for connecting the second cup body assembly 4 and the second cup seat 6 is a rotating locking structure 4-6, wherein a rotating protrusion is provided at the connection part of one of them, and a locking groove is provided on the other. By rotating, the rotating protrusion enters the locking groove to achieve connection and fixation, and by rotating in the opposite direction, disassembly is achieved.

[0107] In one embodiment, the inner wall of the first cooking cavity 100 is provided with a plurality of vertically spaced positioning protrusions a01, and the side of the second cooking component b is provided with a plurality of spaced positioning grooves b01. When the second cooking component b is installed into the first cooking cavity 100, the positioning protrusions a01 are inserted into the positioning grooves b01, thereby restricting the rotation of the second cooking component b. Using the above solution, the rotation of the second cooking component b under the reaction force of food during operation can be restricted. Furthermore, the structure is simple and assembly is convenient.

[0108] In one embodiment, the lower end of the second cooking component b is provided with one or more support portions b02, and the second cooking component b is mounted above the bottom wall of the first cooking cavity 100 via the one or more support portions b02. This design ensures stable support for the second cooking component b. Furthermore, during operation, the buffer reduces vibration between the first cooking component and the first cooking cavity, while also reducing noise.

[0109] When multiple support parts b02 are used, an exhaust channel is formed between adjacent support parts b02, which can exhaust the airflow produced when the first cutter is working, parallel to the air pressure at the bottom of the second cooking component b.

[0110] In one embodiment, the one or more support portions b02 are provided with a buffer member b.1 that contacts the bottom wall of the first cooking cavity 100.

[0111] In some embodiments, in order to facilitate the taking and putting away of the second cooking component b, a handle (not shown) that can be flipped over and stored is provided on the upper side of the second cooking component b.

[0112] Although this application illustrates a scheme in which the second cooking component b is mounted above the bottom wall of the first cooking cavity 100 using one or more support portions b02, in other embodiments, a step may be provided on the side wall of the first cooking cavity 100, and a structure that mates with the step may be provided on the outer side of the second cooking component b to achieve the installation of the second cooking component b onto the first cooking cavity 100. For example, a step may be provided on the upper part of the step on the side wall of the first cooking cavity 100, and a protrusion may be provided on the upper outer side of the second cooking component b. The protrusion of the second cooking component b may be mounted on the step, so that the second cooking component b is suspended as a whole from the first cooking cavity 100.

[0113] In other embodiments, the upper part of the second cooking component b is constructed and acts on the protrusion at the upper port of the first cooking cavity 100. The protrusion of the second cooking component b is installed at the upper port of the first cooking cavity 100, so that the second cooking component b is suspended as a whole from the first cooking cavity 100.

[0114] See Figures 11 to 15 This application also provides a food preparation sub-component b' for detachably coupling with the drive mechanism 3 of a food processor to achieve food chopping. The food preparation sub-component b' includes: a sub-cup body 4', a sub-blade k2”, and a reduction device 5; the sub-cup body 4' has a sub-cooking cavity 400' with a second upper opening 40, and the sub-blade k2” is disposed in the sub-cooking cavity 400'; the reduction device 5 is disposed on the lower side of the bottom of the sub-cooking cavity 400', and includes a reduction mechanism 50. The input end 5.1 of the reduction mechanism 50 is detachably coupled to the drive mechanism 3 at least indirectly, and the output end of the reduction mechanism 50 is drively connected to the sub-blade k2”.

[0115] It also includes a sub-cup holder 6', which is connected to the lower side of the sub-cup body 4'. The deceleration device 5 is disposed inside the sub-cup holder 6'. The input end 5.1 is located in the lower middle part of the sub-cup holder 6'. One or more support parts b02 are provided at the lower end of the sub-cup holder 6'. The sub-cooking component b passes through one or more support parts b02.

[0116] like Figures 11 to 15 In the illustrated embodiment, the sub-cup holder 6' and the sub-cup body 4' are detachable, see details below. Figures 11 to 15 The description of the second cooking component b embodiment shows that the second cup body component 4 corresponds to the sub-cup body 4' of this embodiment, and the second cup holder 6 corresponds to the sub-cup holder 6' of this embodiment. Other features and technical effects are the same.

[0117] See Figures 16 to 19 In the illustrated embodiment, the sub-cup holder 6' and the sub-cup body 4' are not disassembled; see details below. Figures 16 to 19 The description of the second cooking component b embodiment shows that the second cup body component 4 corresponds to the sub-cup body 4' of this embodiment, and the second cup holder 6 corresponds to the sub-cup holder 6' of this embodiment. Other features and technical effects are the same.

[0118] The cooking sub-component b' of this application can be used in conjunction with the first cooking component a. When it is necessary to chop the ingredients into larger particles, the cooking sub-component b' is assembled into the first cooking cavity 100, so that the second input end 5.1 is coupled with the drive mechanism 3. Since the cooking sub-component b' is equipped with a speed reduction device 5, the torque of the sub-blade k2” can be increased to meet the need for chopping food.

[0119] Further technical effects of the cooking sub-component b' are demonstrated in other embodiments of this application.

[0120] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
