Description

Technical Field

[0001] The utility model relates to the field of kitchen appliances, in particular to a multifunctional food processing machine. Background Art

[0002] Traditionally, cutting vegetables in the kitchen involves manual use of knives, a process that is not only inefficient but also carries the risk of injury. To improve efficiency and safety, automatic vegetable cutters have emerged on the market. Operators only need to feed the ingredients, and the cutter automatically completes the cutting process. This is highly efficient, hands-free, and safer.

[0003] For example, the existing patent CN219788555U discloses an electric vegetable cutter that saves manual labor and is easy to use. Although the vegetable cutter is highly efficient, safe and reliable, it has a single function. Since daily cooking requires a combination of meat and vegetables, operators also need to cut meat. Manual meat cutting also has the problem of low efficiency and unsafety. If a dedicated meat cutter on the market is used to cut meat, consumers need to purchase and use two machines for cutting vegetables and meat respectively, which is costly, cumbersome to operate, and requires a lot of cleaning work.

[0004] In the prior art, both vegetable cutters and meat cutters can only achieve a single function. One important reason for this is that the structures and working principles of the vegetable cutter assembly and the meat cutter assembly are quite different. Specifically, the vegetable cutter assembly usually includes a vegetable cutter barrel and a vegetable cutter mounted on the side wall of the vegetable cutter barrel. When it is working, the vegetable cutter barrel and the vegetable cutter need to rotate together to cut the food; while the meat cutter assembly usually includes a knife holder and a rolling cutter group arranged in the knife holder. When it is working, the knife holder must remain stationary, and only the rolling cutter group rotates. This leads to the inevitable different ways of matching the processing chamber and the drive transmission structure with the vegetable cutter barrel and the knife holder / rolling cutter. Therefore, the existing processing chamber is only adapted to the vegetable cutter assembly or the meat cutter assembly. The outer contour of the processing chamber can be adapted to one processing assembly, which is easy to implement. However, the vegetable and meat cleaver assemblies not only operate differently when used in the processing chamber, but also have significantly different external profiles. When both are used in the same processing chamber, considerations must be given to both chamber compatibility and the operational stability of each component. This complicates the design of the specific processing chamber structure and presents significant obstacles to improvements for those skilled in the art. Incorporating both assemblies into the same processing chamber and using the same drive structure would further increase the difficulty of improvement.

[0005] In order to solve the problem of applying two different processing components, the vegetable cutting knife component and the meat cutting knife component, to the same device. In the prior art, there is also patent CN202211035591.7 that discloses a cutting machine that can realize both cutting vegetables and cutting meat in one machine. However, the two processing components of the cutting machine for cutting vegetables and cutting meat need to work at the same time, and the working noise is loud. Moreover, the vegetable cutting knife and the rolling cutter group are driven to rotate by the same rotating shaft at the same time, resulting in a large load on the motor, which not only affects the service life of the motor, but also has the problem of unstable downstream transmission. Moreover, since the second rotating shaft at the output end of the motor must pass through and extend behind the vegetable cutting knife to cooperate with the rolling cutter group, the feeding port is located above the corresponding knife group. A accommodating box is provided between the vegetable cutting knife and the rolling cutter group, and a hopper is provided above it, that is, the accommodating box and the hopper limit the upper and lower positions of the second rotating shaft, which results in the vegetable cutting knife needing to be assembled with the second rotating shaft and cannot be disassembled. Furthermore, the upper portion of the rolling cutter assembly is a feed port with a smaller diameter than the rolling cutter assembly itself. The right side is the base sidewall, the left side is connected to the second rotating shaft, and the lower portion is the first discharge port. This means that the rolling cutter assembly cannot be disassembled. Without the ability to disassemble the cutting knives and rolling cutter assembly, food residue will accumulate on them over time, creating an unpleasant odor and affecting the hygiene of the processed ingredients. Furthermore, placing the two processing components side by side horizontally on a single device results in a larger device, requiring a large footprint and making it unsuitable for home use.

[0039] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0040] 1. The same processing chamber of the same food processor of the present invention can be adapted for use with two different processing assemblies. First, in this application, by providing a tool holder that is locked in place with the processing chamber and a clearance fit between the second processing assembly and the inner wall of the processing chamber, the second processing assembly can rotate and work as a whole within the processing chamber, making the outer contour of the processing chamber compatible with both a tool holder that does not rotate relative to the processing chamber and a second processing assembly that must rotate as a whole relative to the processing chamber. This application also provides a transmission head that drives the first and second processing assemblies to rotate, respectively, and is disposed relative to the mounting opening of the processing chamber, so that the first or second processing assembly can be installed into the processing chamber through the mounting opening so that both can be properly assembled with the transmission head.

[0041] Secondly, in the present application, the first processing component and the second processing component can be installed replaceably, and the first processing component and the second processing component are respectively installed in the processing chamber through the installation port, that is, the two processing components can be replaceably loaded into the processing chamber from the installation port. On the one hand, when working, the driving component only needs to drive one of the processing components to work. Compared with the scheme in the prior art that drives the two processing components to rotate at the same time, the load on the driving component is smaller, especially the direct connection between the driving component and each processing component can effectively improve the working stability of the processing component and reduce the working noise; on the other hand, the first processing component and the second processing component are respectively installed in the processing chamber through the installation port, that is, when the first processing component is working, only the first processing component is loaded into the processing chamber, and when the second processing component is working, only the second processing component is loaded into the processing chamber. That is to say, no matter which processing component is working, the processing chamber only needs to accommodate space for one processing component. Compared with the scheme in the prior art that needs to accommodate two processing components at the same time, the lateral volume of the processing chamber is greatly reduced, thereby reducing the volume of the whole machine, which is conducive to home use. In addition, the two processing components can be replaced by each other, and the two processing components can be disassembled from the processing chamber as a whole, which provides conditions for their replacement and provides convenience for removing and cleaning the processing components, solving the problem of difficulty in cleaning caused by the inability to disassemble the processing components in the prior art, and avoiding residual dirt on the processing components to generate odor and affect food processing hygiene.

[0042] The first processing component can be used to slice meat ingredients by moving only the rolling cutter group, while the second processing component is used to process ingredients that require rotation, such as vegetables and noodles. In other words, the first and second processing components are mainly used to process different types of ingredients, or the first and second processing components can also process the same ingredients into different forms. For example, the rolling cutter group of the first processing component can be used to slice vegetables, while the second processing component can be used to shred or dice vegetables. This can enrich the functions and usage scenarios of the food processor and meet more user needs.

[0043] In summary, the solution of the present application, by making the processing chamber compatible with a first processing assembly whose tool holder does not rotate and a second processing assembly that rotates as a whole, integrates processing assemblies with significantly different working principles and larger external contours into a single processing chamber of a food processor, thereby expanding the processing functions of a variety of different food ingredients. Furthermore, the first processing assembly and the second processing assembly can be interchangeably installed in the processing chamber, reducing the volume of the processing chamber for household use, and the processing assemblies are easy to disassemble and clean, ensuring hygienic use of the processing assemblies. Furthermore, in the present application, only one processing assembly is in operation at a time, which reduces the load on the drive assembly, improves working stability, and reduces noise.

[0044] 2. In the present application, a mounting port is provided, which includes a first opening centered on the central axis of the output shaft and a second opening extending radially outward from the first opening. The first opening can be used to install the rolling cutter group of the first processing component and to accommodate the second processing component, while the second opening is used to allow the tool holder of the first processing component to extend therein, thereby achieving that one mounting port can be compatible with two processing components with greatly different forms, especially compatible with two processing components with opposite working states: one processing component is flatter and needs to be circumferentially fixed with the processing cavity, while the other processing component needs to rotate as a whole within the mounting port. In addition, the minimum distance from the edge of the first opening to the central axis of the output shaft is greater than the rotation radius of the second processing component, that is, the second processing component maintains a gap with the edge of the first opening, thereby ensuring the stability of the second processing component in the overall rotation processing of food and reducing the risk of contact with the first opening.

[0045] Furthermore, by providing second openings symmetrically located on either side of the first opening, the processing chamber can maintain overall alignment when mounted on the machine base, reducing the deflection of the processing chamber during operation. Furthermore, the tool holder is provided with an adapter portion adapted to the two second openings, which provides circumferential anti-rotation between the tool holder and the inner wall of the processing chamber. This arrangement also positions the adapter portion away from the first opening and the feeding port, preventing food introduced from the feeding port from splashing onto the adapter portion during processing, causing the tool holder to become stuck in the mounting chamber and affecting the disassembly experience of the first processing assembly.

[0046] 3. In the prior art, the drive head of the vegetable cutter assembly needs to both drive and axially limit the cutter assembly, while the drive head of the rolling cutter assembly only needs to engage the cutter assembly. This results in significant structural differences between the drive heads of the two different processing assemblies. Thus, without increasing structural complexity, those skilled in the art would readily consider providing different drive heads that can be detachably connected to the main unit if the vegetable cutter assembly and the meat cutter assembly can be used in the same device. When a particular processing assembly is used, the corresponding drive head can be replaced. This solution would also simplify the structural design. However, the present application adopts a different, seemingly more complex solution: integrating two different drive heads, while still being able to adapt to the first and second processing assemblies. Specifically, by configuring the drive head with coaxially arranged first and second pivots, each can be adapted to the working state regardless of the processing assembly, and high coaxiality further enhances operational stability. The integration of the first and second pivots solves the operational complexity of the prior art, which requires repeated replacement of the drive head.

[0047] 4. When the second processing assembly of the present application is in operation, the rotation speed of the second processing assembly during rotary cutting is usually relatively high, and there is a situation where one end of the second processing assembly is engaged with the transmission head and the other end is suspended in the air. This requires that the second processing assembly needs to obtain stable support at the end connected to the transmission head. The present application is able to provide effective and reliable position limiting for the second processing assembly while ensuring the transmission connection effect through the first pivoting portion. For the first processing assembly, under the premise that the tool holder is limited by the processing chamber and the rolling cutter group usually only requires a relatively low operating speed, its own stability is relatively good, which can reduce the connection requirements of the transmission head to the rolling cutter group. Furthermore, the first processing assembly may be equipped with a reduction gearbox, and a shaft structure that is connected to the second pivot portion usually extends from the reduction gearbox. The shaft can meet the strength requirements of the connection to the rolling cutter group by using a smaller outer diameter. If a larger outer diameter is used, the internal space occupied by the reduction gearbox will be increased, thereby increasing the volume of the reduction gearbox, increasing the cost, and increasing the volume of the processing chamber. When the volume of the second processing assembly remains unchanged, the gap between the second processing assembly and the inner wall of the processing chamber will be too large. When the second processing assembly shakes, it is not conducive to the return of the second processing assembly, thereby reducing the working stability of the second processing assembly. Therefore, in the solution of the present application, the second pivot portion that cooperates with the rolling cutter group can adopt a relatively small outer diameter, and the first pivot portion that cooperates with the second processing assembly can adopt a relatively large outer diameter to meet the strength requirements of the transmission head for connecting the second processing assembly.

[0048] To further enhance the operational stability of the second processing assembly, in a preferred embodiment, the first pivoting portion includes a plug-in portion that plugs into and engages with the second processing assembly to achieve transmission engagement, and a stop portion that bends relative to the plug-in portion and serves to axially limit the second processing assembly. After the plug-in portion and the second processing assembly are plugged together and installed, the edge of the through-hole engages with the stop portion, and the stop portion cooperates with the end stop of the second processing assembly, thereby firmly connecting the second processing assembly to the transmission head. During the second processing assembly's rotation, the second processing assembly will not disengage from the transmission head, ensuring operational stability.

[0049] In order to further improve the working stability of the first processing assembly, as a preferred embodiment, the first pivot portion is located outside the second pivot portion, and the second pivot portion is protruded relative to the first pivot portion toward the side away from the output shaft. By arranging the second pivot portion away from the output shaft, the matching stroke between the second pivot portion and the input end of the rolling cutter assembly can be shortened, so that the transmission chain is shortened, which is beneficial to improving the stability of the transmission. In addition, when the second pivot portion with a smaller outer diameter is arranged close to the output shaft and the first pivot portion with a larger outer diameter is arranged away from the output shaft, since the first pivot portion has to support the second processing assembly to form a suspended state, when the distance from the output shaft to the first pivot portion increases, the probability of the second processing assembly shaking during rotation increases, which is not conducive to the stable operation of the second processing assembly. In the long run, this will increase the risk of the first pivot portion or the connection between the first pivot portion and the second pivot portion breaking, resulting in a decrease in the service life of the structure.

[0050] 5. In order to ensure that the tool holder does not move relative to the processing chamber when the first processing assembly is in working state, thereby ensuring the stability and reliability of the rolling cutter group, the present application sets a limiting structure between the tool holder and the processing chamber to limit the installation of the tool holder.

[0051] In a preferred embodiment, one of the machining chamber and the tool holder is provided with a slide groove, and the other is provided with a stopper that slidably engages with the slide groove. When the first machining assembly is installed, the stopper engages with the slide groove to prevent circumferential rotation of the machining chamber and the tool holder. The combination of the slide groove and the stopper provides a simple structure, and the slide groove occupies little space in the machining chamber, without interfering with the machining chamber's ability to accommodate the second machining assembly, thereby ensuring the machining chamber's compatibility with both machining assemblies.

[0052] 6. When processing food, since the food falls from the feeding port from top to bottom, when cutting the food, the cutting force on the food is strongest in the top area of the processing component, and the food is most likely to fly out into the gap between the processing component and the processing chamber, especially splashing into the gap between the second processing component and the processing chamber, which causes the most serious problems and may directly cause the second processing component to get stuck. Therefore, in this application, an inwardly convex retaining rib is provided in the processing chamber, and the retaining rib is provided above the horizontal plane where the central axis of the output shaft is located, that is, it is used to block the area where splashing is most likely to occur, so that the retaining rib cooperates with the first processing component or the second processing component to prevent food from splashing, and can also ensure the cleanliness of the processing chamber. In addition, the retaining rib can also straighten the processing component when radial shaking occurs, thereby improving the uniformity of food processing. In addition, the ribs are raised structures, which are more three-dimensional and have a smaller contact area with the food than the smooth inner wall of the processing chamber. When the cut vegetables splash onto the ribs, they can be bounced back quickly and promptly and fall back into the processing chamber, ensuring that the cut food can be fully discharged, reducing food waste, and avoiding some food splashing and sticking to the inner wall of the processing chamber, which increases the user's cleaning burden.

[0053] 7. Under the premise that the second processing component is a vegetable cutting knife component, since one end of the roller is a fixed end and the other end is a cantilever end, the cantilever end is prone to radial shaking during rotation. On the one hand, it causes friction and wear with the inner wall of the processing chamber during shaking, generating noise. On the other hand, it causes the vegetable cutting knife component to have a tortuous path during rotation, resulting in uneven cutting of the food. In order to solve the aforementioned problems of shaking noise and uneven cutting of food, the present application provides a second processing component including a bracket and a cutting piece detachably mounted on the side wall of the bracket, one end of the bracket is fixed to the transmission head, and the other end is suspended relative to the processing chamber. The bracket is provided with an anti-collision ring that protrudes radially outward relative to the cutting piece, and the anti-collision ring is in clearance with the retaining rib.

[0054] The use of a radially outward-projecting anti-collision ring relative to the cutting element ensures that if the cantilever end of the bracket deflects, the anti-collision ring, rather than the cutting element, comes into contact with the retaining rib first. This prevents deformation of the cutting element, wear of the machining cavity, or even slippage of the cutting element relative to the bracket. The protruding anti-collision ring further reduces the amount of deflection of the cantilever end of the bracket relative to the machining cavity, making it easier for the retaining rib to straighten the bracket, improving the overall rotary cutting stability and operating noise of the second machining assembly.

[0055] 8. The rolling cutter group is generally used to cut meat slices, and the speed required is lower than that of cutting vegetables. In order to achieve the low-speed output of the first processing component to cut meat, as a preferred embodiment, the first processing component also includes a reduction gearbox provided on the tool holder, and the drive component is connected to the rolling cutter group through the reduction gearbox, and the speed of the rolling cutter group is lower than the speed of the second processing component. By integrating the reduction gearbox on the tool holder, the requirements for the setting of the reduction structure of the machine base can be reduced, and the rolling cutter group can be guaranteed to output a low speed to work without relying on an external reduction gearbox; the second processing component can output a relatively high speed to achieve functions such as cutting vegetables, kneading noodles, and extruding noodles.

[0056] 9. To minimize the volume of the processing chamber, simplify the structural configuration, and achieve the adaptation of two processing components to one processing chamber and one feeding port, as a preferred embodiment, a feeding port is provided above the processing chamber. When the first processing component and the second processing component are installed, the rolling cutter assembly and the second processing component are exposed through the feeding port. When a single feeding port is used, the rolling cutter assembly and the second processing component are exposed through the feeding port. That is, the first processing component and the second processing component are both installed with the same feeding port as the reference. The difference in the installation position of the first processing component and the second processing component is small, which reduces the user's requirements for the installation of different processing components, facilitates the rapid switching of different processing components, and ensures the accuracy of the installation position.

[0057] 10. In order to reduce the probability of contact between different ingredients and avoid cross-flavoring, and to ensure reliable transmission of the rolling cutter group when the rolling cutter group is far away from the driving assembly, a feeding port is provided, including a first feeding port and a second feeding port spaced apart. The first feeding port is arranged relative to the second feeding port and is far away from the output end of the driving assembly. The food processor includes a connecting rod, and the rolling cutter group is connected to the output end of the driving assembly through the connecting rod. When the first processing assembly is installed in place, the rolling cutter group is aligned with the first feeding port. When the second processing assembly is installed in place, the second processing assembly is aligned with the second feeding port.

[0058] Using two independent feeding ports allows for separate feeding of vegetables, meat, or other ingredients, reducing the likelihood of different ingredients coming into contact, thus preventing odor contamination and ensuring a consistent taste. The connecting rod acts as an intermediate connection. Although its provision extends the transmission path, the connecting rod itself is lightweight and lacks additional accessories, resulting in a minimal load on the drive end. This facilitates stable transmission of power to the rolling cutter assembly through the connecting rod when the motor load is low, ensuring stable operation of the rolling cutter assembly.

[0073] like Figures 1 to 11 As shown, the present application provides a multifunctional food processing machine, comprising a base 10 having a drive assembly and a processing chamber 11. Preferably, the processing chamber 11 is disposed on the base. The output shaft 291 of the drive assembly is provided with a transmission head 14 extending into the processing chamber 11. One end of the processing chamber 11 is provided with a mounting opening 111. The transmission head 14 is located within the processing chamber 11 and is disposed opposite the mounting opening 111.

[0074] The processing chamber 11 has a feeding port at the top for feeding food, which is in communication with the processing chamber. A first processing assembly 12 and a second processing assembly 13 are replaceably installed in the processing chamber 11. One end of the processing chamber 11 has a mounting port 111, so that the first processing assembly 12 and the second processing assembly 13 can be separately installed in the processing chamber 11 through the mounting port 111. In other words, the first processing assembly 12 and the second processing assembly 13 are installed and used independently: when the first processing assembly 12 is in operation, the first processing assembly 12 is installed in the processing chamber 11 through the mounting port 111, and the second processing assembly 13 is not installed; when the second processing assembly 13 is in operation, only the second processing assembly 13 is installed in the processing chamber 11 through the mounting port 111, and the first processing assembly 12 is not installed. The first processing assembly 12 and the second processing assembly 13 are replaceably engaged with the transmission head 14. The transmission head 14 is located in the processing chamber 11 and is arranged opposite to the installation port 11, so that the first processing assembly 12 or the second processing assembly 13 can be installed in the processing chamber 11 through the installation port 111 so that they can be well assembled with the transmission head 14.

[0075] The first processing assembly 12 includes a tool holder 121 and a rolling cutter group 122 provided on the tool holder 121. The maximum dimension of the edge of the tool holder 121 passing through the central axis of the output shaft is larger than the maximum dimension of the edge of the second processing assembly 13 passing through the central axis of the output shaft. When the first processing assembly 12 is in working condition, the processing chamber 11 and the tool holder 121 are circumferentially fixed, and only the rolling cutter group 122 rotates under the action of the driving assembly to process food. When the second processing assembly 13 is in working condition, the outer peripheral surface of the second processing assembly 13 is gap-fitted with the inner wall of the processing chamber 11, and the second processing assembly 13 rotates as a whole under the action of the driving assembly to process food.

[0076] In this application, reference Figure 2 Because the first machining assembly is equipped with two sets of rolling cutter assemblies, it is flatter overall, with its width greater than its height. The machining chamber is also flattened to accommodate the first machining assembly. Therefore, to minimize the height of the machining chamber and thus reduce the overall size of the machine, the maximum size of the second machining assembly is limited by the vertical height of the machining chamber. Specifically, the maximum dimension of the edge of the tool holder 121 passing through the central axis of the output shaft is set to be greater than the maximum dimension of the edge of the second machining assembly 13 passing through the central axis of the output shaft.

[0077] The same processing chamber 11 of the same food processor of the present invention is adapted for use with at least two different processing assemblies. First, in this embodiment, by providing a tool holder 121 with a fixed rotation fit within the processing chamber 11 and a second processing assembly 13 with a clearance fit within the inner wall of the processing chamber 11, the second processing assembly 13 can rotate and operate as a whole within the processing chamber 11. This allows the outer contour of the processing chamber 11 to accommodate both the tool holder 121, which does not rotate relative to the processing chamber 11, and the second processing assembly 13, which must rotate as a whole relative to the processing chamber 11.

[0078] Secondly, the two processing components can be replaceably installed in the processing chamber 11 through the installation port 111. On the one hand, when working, the driving component only needs to drive one of the processing components to work. Compared with the solution in the prior art that drives the two processing components to rotate at the same time, the load on the driving component is smaller, especially the direct connection between the driving component and each processing component, which can effectively improve the working stability of the processing components and reduce the working noise; on the other hand, the first processing component 12 and the second processing component 13 are respectively installed in the processing chamber 11 through the installation port 111, that is, when the first processing component 12 is working, only the first processing component 12 is installed in the processing chamber, and when the second processing component 13 is working, only the second processing component 13 is installed in the processing chamber. That is to say, no matter which processing component is working, the processing chamber 11 only needs to accommodate space for one processing component. Compared with the solution in the prior art that needs to accommodate two processing components horizontally at the same time, the lateral volume of the processing chamber is greatly reduced, thereby reducing the volume of the entire machine, which is conducive to home use. In addition, the two processing components can be replaced by each other. The two processing components can be disassembled from the processing chamber as a whole, which provides conditions for their replacement. The disassembly also provides convenience for taking out the processing components for cleaning, solving the problem of difficulty in cleaning caused by the inability to disassemble the processing components in the prior art, and avoiding residual dirt on the processing components to generate odor and affect food processing hygiene.

[0079] The first processing assembly 12 can be used to slice meat ingredients by moving only the rolling cutter assembly, while the second processing assembly is used to process ingredients that require rotation, such as vegetables and noodles. In other words, the first processing assembly 12 and the second processing assembly 13 are primarily used to process different types of ingredients, or the first processing assembly 12 and the second processing assembly 13 can also process the same ingredient into different forms. For example, the rolling cutter assembly of the first processing assembly can be used to slice vegetables, while the second processing assembly can be used to shred or dice vegetables. This enriches the functions and usage scenarios of the food processor and meets more user needs.

[0080] In summary, the above-mentioned embodiment of the present application, by making the processing chamber 111 compatible with the first processing assembly 13 of the tool holder 121 that does not rotate and the second processing assembly 13 that rotates as a whole, integrates processing assemblies with greatly different working principles and large external contours into a single processing chamber 11 of a food processor to expand the processing functions of different food materials with greatly different functions. In addition, the first processing assembly 12 and the second processing assembly 13 can be installed replaceably in the processing chamber 11, so that the volume of the processing chamber 11 is reduced and it is convenient for household use. The processing assemblies are easy to disassemble and clean, which can ensure the hygienic use of the processing assemblies. In addition, in the present application, only one processing assembly is in operation at a time, and the load on the drive assembly is small, which can improve working stability and reduce noise.

[0081] In some preferred embodiments of the present application, Figures 1 to 3As shown, the processing chamber 11 is detachably mounted on the machine base 10, which facilitates disassembly and cleaning of the processing chamber 11. The first processing assembly 12 and the second processing assembly 13 are both detachably mounted on the processing chamber 11, which also facilitates cleaning of the first processing assembly 12 and the second processing assembly 13. For example, the first processing assembly 12 and the second processing assembly 13 can be directly rinsed under the faucet.

[0082] Specifically, refer to Figure 3 The mounting port 111 includes the center axis of the output shaft 291 ( Figure 3 The mounting opening 111 comprises a first opening 1111 centered on the horizontal dotted line (shown in FIG) and a second opening 1112 extending radially outward from the first opening 1111. The first opening 1111 can be used to install the rolling cutter group 122 of the first processing assembly 12 and accommodate the second processing assembly 13. The second opening 1113 is used to allow the tool holder 121 of the first processing assembly 12 to extend therethrough. This allows a single mounting opening 111 to accommodate two processing assemblies with significantly different shapes, particularly two processing assemblies with opposite working conditions: one flatter processing assembly that needs to be circumferentially fixed to the processing chamber, and the other that needs to rotate integrally within the mounting opening.

[0083] Preferably, Figure 3 There are two second openings 1112, which are symmetrically arranged on both sides of the first opening 1111 along the width direction, so that the processing chamber 11 can maintain the centering as a whole when installed on the machine base, reducing the deflection of the processing chamber during operation. Figure 3 In the figure, the two vertical dashed lines represent one of the dividing lines between the first opening and the second opening. When the rolling cutter assembly 122 of the first processing assembly 12 is inserted through the first opening 1111, the tool holder 121 of the first processing assembly 12 extends into the processing chamber 11 through the second opening 1112 and engages with the inner wall of the processing chamber 11 for rotation prevention. The second processing assembly 13 is inserted into the processing chamber 11 through the first opening 1111, and the minimum distance from the edge of the first opening 1111 to the central axis of the output shaft is greater than the rotation radius of the second processing assembly 13. That is, a gap is maintained between the second processing assembly 13 and the edge of the first opening 1111, ensuring the stability of the second processing assembly 13 in overall rotational processing of food, and reducing the risk of contact with the first opening 1111.

[0084] In a more preferred embodiment, the tool holder 121 is further provided with an adapter portion adapted to fit the two second openings 1112. The adapter portion prevents circumferential rotation between the tool holder 121 and the inner wall of the processing chamber 11. This arrangement also positions the adapter portion away from the first opening 1111 and the feeding port, preventing food introduced from the feeding port from splashing onto the adapter portion during processing, causing the tool holder to become stuck in the installation chamber and affecting the disassembly experience of the first processing assembly.

[0085] Generally, the rolling cutter assembly 122 can be mainly used for cutting meat. The type of the second processing assembly 13 is not limited. For example, the second processing assembly 13 can be any one of a vegetable cutting assembly, a dough mixer 18 or an extrusion screw 181. The vegetable cutting assembly generally includes a roller 131 and a cutting member 132 provided on the roller 131, such as Figure 4 As shown, the cutting member 132 can be different types of accessories that can be replaceably arranged on the roller 131. The cutting member 132 includes a slicing knife 1321, a shredder knife 1322, a grinding knife 1323, etc., which can enrich the cutting forms of vegetables. The roller 131, the dough kneading rod and the extrusion screw are all integrally rotating structures with the same working principle, and therefore can all be applied to the processing chamber 11 of the present application for use. Preferably, the rolling cutter group 122 includes two groups of rolling cutters arranged along the width direction of the tool holder 121, and the maximum lateral width of the tool holder 121 is greater than the maximum lateral width of the second processing component 13. The processing chamber 11 of the present application can adapt to processing components with different external contours, and has higher requirements on the shape of the processing chamber 11 than the prior art. The processing chamber 11 of the present application can accommodate both flat-type tool holders 121 and relatively round processing components, and has good compatibility.

[0086] like Figure 2 As shown, the tool holder 121 is flat. When the second processing component 13 is a vegetable cutting knife component, the roller 131 is cylindrical. The maximum lateral width of the tool holder 121 is greater than the maximum lateral width of the roller 131. To ensure the compatibility of the processing chamber 11, the lateral width of the processing chamber 11 should be set according to the maximum lateral width of the tool holder 121. At the same time, the height of the processing chamber 11 is greater than the maximum height of the tool holder 121 and the roller 131.

[0087] Specifically, the adapting portion is a portion on the tool holder that conforms to the second opening, for example Figure 2 、 3 As shown, the mounting opening resembles a runway-shaped circular structure, so the cross-section of the tool holder where it is inserted into the mounting opening also has a runway-shaped circular structure, and the adapting portion is composed of two semicircular portions on the tool holder's end face. Therefore, when the tool holder and the mounting opening are contoured and adapted, the gap between them is small, and the mounting opening is non-circular, there is no need to provide an additional stopper on the tool holder to achieve circumferential rotational stop between the tool holder and the mounting opening. When a stopper is provided on the adapting portion, the following implementation schemes are provided in this application:

[0088] As a preferred embodiment, one of the processing chamber 11 and the tool holder 121 is provided with a slide groove 19, and the other is provided with a stopper that slidably engages with the slide groove 19. When the first processing assembly 12 is installed, the stopper engages with the slide groove 19 to prevent the processing chamber and the tool holder from rotating circumferentially. The combined structure of the slide groove 19 and the stopper is relatively simple. The slide groove 19 occupies little space in the processing chamber 11, thus preventing the processing chamber 11 from being excessively large. Furthermore, the slide groove 19 does not affect the processing chamber 11's ability to accommodate the second processing assembly 13, thus ensuring the processing chamber 11's compatibility with both processing assemblies.

[0089] Specifically, such as Figure 2 、 3 As shown in Figures 6 and 7, the maximum size of the tool holder 121 is larger than the maximum size of the second processing component 13. The tool holder 121 is provided with a limiting portion on both sides along the width direction, that is, the distance between the two ends of the limiting portion along the width direction is greater than the maximum outer diameter of the second processing component. The limiting portion is a limiting rib 20 protruding from the outer wall of the tool holder 121, that is, the limiting rib 20 is the adapter. The inner wall of the processing chamber 11 is provided with a radially outwardly recessed slide 19, and the limiting rib 20 is slidably installed in the slide 19. When the tool holder 121 of this embodiment is slidably installed, the tool holder 121 and the limiting rib 20 are both extended into the inner side of the processing chamber 11 for installation, which is conducive to the rapid alignment of the limiting rib 20 and the slide 19, thereby improving the installation efficiency and promoting the smooth assembly of the tool holder 121.

[0090] As another preferred embodiment, the limiting portion and the tool holder are two independent components. There is no need to restrict the maximum outer diameter of the tool holder relative to the maximum outer diameter of the second machining assembly. It is sufficient to ensure that the limiting portion can circumferentially constrain the tool holder within the machining chamber. Specifically, the limiting portion may be a rib that slides into a slot installed in the machining chamber. The rib may engage the tool holder via a snap-fit connection or a slot-fitting connection.

[0091] As another preferred embodiment: Figure 2 As shown, the side of the chute 19 radially closer to the center of the processing chamber 11 is open, allowing the limiting rib 20 to be inserted through the open side. The other side is closed, so that the limiting rib 20 remains inside the processing chamber 11 after insertion. That is, the peripheral sidewall of the processing chamber 11 in this example is a closed structure, which can prevent food from flying out and reduce food waste. In this case, the limiting rib 20 is an adapter.

[0092] As another preferred implementation scheme: the slide groove 19 radially penetrates the side wall of the processing cavity 11. When the limiting rib 20 is plugged into the slide groove 19, a part of the limiting rib 20 can extend to the outside of the slide groove 19, and the limiting rib 20 is only plugged into the slide groove 19. Under the premise of ensuring the plug-in effect of the limiting rib 20, it is beneficial to reduce the material usage of the processing cavity 11 and save costs.

[0093] Of course, it is understandable that in other embodiments, the slide groove 19 can be set as a long through-hole structure, and a hole can be directly opened on the side wall of the processing chamber 11 without a protruding setting, which is beneficial to further reduce the lateral volume of the processing chamber 11.

[0094] As another preferred embodiment: the slide groove 19 radially penetrates the side wall of the processing cavity 11, and the limiting rib 20 has a certain elasticity. When the limiting rib 20 and the slide groove 19 are plugged into place, a part of the limiting rib 20 extends to the outside of the slide groove 19, and the extended part can be bent and attached to the outer wall of the processing cavity 11 to strengthen the fixing effect of the limiting rib 20 and improve the reliability of the tool holder 121.

[0095] As another preferred embodiment: Figure 7 and Figure 8 As shown, the limiting portion is a limiting rib 20 provided on the outer wall of the tool holder 121 and bent toward the drive assembly. The outer wall of the processing chamber 11 is provided with a radially inwardly protruding slide 19, and the limiting rib 20 is slidably mounted in the slide 19. Since the slide 19 is radially inwardly protruding in this embodiment, the lateral volume of the processing chamber 11 is reduced, which can promote the miniaturization of the entire machine. In addition, the tool holder 121 is partially located inside the processing chamber 11 and partially located outside the processing chamber 11, and the installation method is novel.

[0096] As another preferred embodiment, the limiting portion is a roller provided on the blade holder 121. Preferably, the roller can be provided on the side or bottom of the blade holder 121. The inner wall of the processing chamber 11 is provided with a slide groove 19, and the roller is slidably mounted in the slide groove 19. The slide groove 19 is provided with a sensor for sensing the position of the roller. This embodiment adopts a roller structure to slide more smoothly, and can increase the sliding speed whether the blade holder 121 is installed in the processing chamber 11 or removed from the processing chamber 11, thereby improving the efficiency of the installation and removal of the blade holder 121. In addition, the use of the sensor to sense the position of the roller can provide feedback that the blade holder 121 is installed in place, so that the rolling cutter assembly 122 on the blade holder 121 is in the optimal position to ensure the cutting effect of the food.

[0097] Regarding the number of rollers on one side, one roller can be set in the middle position of the tool holder 121 in the axial direction, or two rollers can be set at the positions of the two ends of the tool holder 121 in the axial direction. When one roller is set, the sensing part is set in the middle of the slide 19. When two rollers are set, the sensing part is set at one end of the slide 19 close to the drive assembly. When the sensing part senses the roller, the tool holder 121 moves into position, completing the installation of the tool holder 121. A matching part is provided at the position of the roller or tool holder 121 corresponding to the roller. The sensing part and the matching part are, for example, a magnetic matching structure, or the sensing part is a reed switch and the matching part is a magnet. It can be understood that the sensing part can also be used for the sensing protrusion provided on the slide 19 to limit the tool holder from sliding out of the window during operation after it is installed in place.

[0098] In a specific application scenario, when the second processing component is a vegetable cutting knife component, the structure of the transmission head connected to the vegetable cutting barrel and the transmission head connected to the rolling cutter group in the prior art are different. Specifically, the transmission head of the vegetable cutting knife component needs to transmit and axially limit the vegetable cutting knife component, while the transmission head of the rolling cutter group only needs to transmit engagement, which leads to a large difference in the transmission head structure of these two different processing components. In this way, without increasing the complexity of the structure, it is easy for those skilled in the art to think that when the vegetable cutting knife component and the meat cutting knife component can be applied to the same device, different forms of transmission heads that can be detachably connected to the main machine can be provided, and when a certain processing component is used, the corresponding transmission head can be replaced. Although this solution can simplify the structural design.

[0099] In the present application, however, another seemingly more complicated solution is adopted, which is to integrate two different forms of transmission heads, which can still adapt to the transmission of the first processing component 12 and the second processing component 13. Specifically, by setting the transmission head 14 to a coaxially arranged first pivot part 15 and a second pivot part 16, one of the first pivot part 15 and the second pivot part 16 is in transmission engagement with the first processing component 12, and the other is in transmission engagement with the second processing component 13, so that no matter which processing component is in the working state, it can be adapted separately, and the high coaxiality is more conducive to improving the working stability. The first pivot part 15 and the second pivot part 16 are integrated together, which solves the problem of the complicated operation of repeatedly replacing the transmission head in the prior art. The present application integrates different pivot parts on the same transmission head, which can save the user's operation amount and improve the user experience under the premise of matching different processing components.

[0100] While studying specific preferred solutions, the applicant also discovered that when the second processing assembly of the present application is in operation, there are two situations: one in which one end of the second processing assembly is engaged with the transmission head and the other end is suspended; the other in which one end of the processing assembly is fixed to the transmission head and the other end requires a third member to achieve position limiting. Furthermore, under normal circumstances, the rotational speed of the second processing assembly during rotary cutting is relatively fast, and the operating vibration is more intense, which requires the second processing assembly to obtain stable support at the end connected to the transmission head. As for the first processing assembly, under the premise that the tool holder is limited by the processing chamber and the rolling cutter group generally only requires a relatively low operating speed, its inherent stability is relatively good, which can reduce the connection requirements of the transmission head to the rolling cutter group.

[0101] Therefore, the utility model provides a transmission head 14, the end of the transmission head 14 away from the output shaft includes a first pivot part 15 that is transmission-engaged with the second processing component 13, and a second pivot part 16 that is plugged into the input end of the rolling cutter group 122 to achieve transmission engagement. The outer diameter of the first pivot part 15 is larger than the outer diameter of the second pivot part 16, so that the first pivot part 15 with a larger outer diameter and better strength is adapted to the second processing component, thereby improving the working stability of the second processing component, and allowing the second pivot part 16 with a smaller diameter to be transmission-connected with the first processing component. While ensuring the working stability of the first processing component, the overall volume of the first processing component can also be effectively controlled.

[0102] The reason is that the first processing component may be equipped with a reduction gearbox, and usually an axis structure extending from the reduction gearbox is connected to the second pivot part 16. The shaft can meet the strength requirements of the connection to the rolling cutter group with a smaller outer diameter. If a larger outer diameter is used, the internal space occupied by the reduction gearbox will be increased, thereby increasing the volume of the reduction gearbox, increasing the cost and increasing the volume of the processing chamber. When the volume of the second processing component remains unchanged, the gap between the second processing component and the inner wall of the processing chamber will be too large. When the second processing component shakes, it is not conducive to the return of the second processing component, thereby reducing the stability of the second processing component.

[0103] Therefore, in the solution of the present application, the second pivot part 16 cooperating with the rolling cutter group can adopt a relatively small outer diameter, and the first pivot part 15 cooperating with the second processing component can adopt a relatively large outer diameter to meet the strength requirements of the transmission head connecting the second processing component.

[0104] In one embodiment, the first pivot portion 15 includes a plug-in portion 151 that is plugged into and matched with the second processing component 13 to achieve transmission engagement, and a stop portion 152 that is bent relative to the plug-in portion 151 and is used to axially limit the second processing component 13. The second processing component includes a bracket and a cutting piece 132 provided on the bracket. The end plate of the bracket is provided with a through hole 17 corresponding to the shape of the plug-in portion 151. After the plug-in portion 151 and the stop portion 152 are aligned and inserted into the through hole 17, they are rotated relative to the through hole 17 until the edge of the through hole 17 engages with the stop portion, that is, the stop portion 152 extends into the through hole 17 and rotates to be misaligned with the through hole, thereby limiting the bracket of the second processing component 13 to the first pivot portion 15 or the second pivot portion 16. Specifically, the second processing component 13 is a vegetable cutting knife component as an example for explanation. It includes a bracket that is a roller 131, and a cutting piece 132 on the side wall of the roller 131:

[0105] In a specific example, the first pivoting portion 15 is a turn buckle, and a through hole 17 is provided on the bottom wall of the drum 131. The second pivoting portion 16 can extend into the drum 131 through the through hole 17. The first pivoting portion 15 only extends into the drum 131 when aligned with the through hole 17, and by rotating to deviate from the through hole 17, the turn buckle is engaged with the bottom wall of the drum 131. Specifically, the plug-in portion 151 extends in a direction away from the output shaft and bends at the end to form a stop portion 152. The plug-in portion 151 and the stop portion 152 form an L-shaped structure. When the first pivoting portion 15 is aligned with the through hole 17, the stop portion 152 is extended into the drum 131, and then the stop portion 152 is misaligned with the through hole 17 by rotating at an appropriate angle so as to be hooked on the bottom wall of the drum 131. This can achieve the axial limitation of the drum 131 by the first pivoting portion 15.

[0106] It is understandable that the bracket may not be roller-shaped, but may simply be provided with an end face adapted to the connector and a cutting piece directly provided on the end face, or a transverse rod body may be provided on the end face to mount the cutting piece.

[0107] When the first pivoting portion 15 is a turn buckle, its location is not limited. For example, in one embodiment, Figure 5 As shown, the transmission head 14 includes a stopper 141, and the first pivot portion 15 is provided on the stopper 141. When the transmission head 14 and the roller 131 are installed in place, the stopper 141 is located outside the bottom wall of the roller 131. In another embodiment, as shown in FIG. Figure 11 As shown, the transmission head 14 includes a stopper 141 and a boss 142 protruding from the stopper 141 , and the first pivot portion 15 is disposed on an outer peripheral wall of the boss 142 .

[0108] It can be understood that when the first pivot portion 15 is a turn buckle, the shape of the turn buckle is not limited to the above-mentioned L-shape. For example, in another example, the transmission head 14 includes a stopper 141 and a boss 142 protruding from the stopper 141. The first pivot portion 15 is a plurality of turn buckles provided on the outer peripheral wall of the boss 142. In order to simplify the structure of the turn buckle, the turn buckle is, for example, a strip block protruding radially outward from the outer peripheral wall of the boss 142.

[0109] To achieve position limiting of the roller 131 by the first pivoting portion 15, in another embodiment, the transmission head 14 includes a stopper 141, which is a mounting plate. A gap is defined between the first pivoting portion 15 and the mounting plate. When the transmission head 14 and the roller 131 are properly installed, the bottom wall of the roller 131 engages in the gap. By engaging the bottom wall of the roller 131 in the gap, the gap can be used to clamp the bottom wall of the roller 131, achieving secure position limiting.

[0110] In another embodiment of the present application, the transmission head is not provided with a stopper, but rather a third component is used to provide the stopper. For example, when the second processing component is an extrusion screw or a dough kneading rod, the mounting opening of the processing chamber, i.e., the lateral opening of the processing chamber, is provided with an end cap, so that one end of the extrusion screw (or dough kneading rod) is in driving engagement with the transmission head, and the other end is in a positional stop with the end cap.

[0111] Furthermore, regarding the distribution of the first pivot portion 15 and the second pivot portion 16, in one embodiment, the first pivot portion 15 and the second pivot portion 16 are arranged sequentially in a direction away from the output shaft, i.e., the first pivot portion 15 is located outside the second pivot portion, and the second pivot portion 16 is arranged to protrude away from the output shaft relative to the first pivot portion 15. This facilitates user identification of the pivot portions and prevents incorrect installation. Furthermore, by locating the second pivot portion 16 away from the output shaft, the travel between the second pivot portion 16 and the input end of the rolling cutter assembly is shortened, shortening the transmission chain and improving transmission stability. In addition, when the second pivot part 16 with a smaller outer diameter is arranged close to the output shaft and the first pivot part 15 with a larger outer diameter is arranged away from the output shaft, since the first pivot part 15 has to support the second processing component to form a suspended state, when the distance from the output shaft to the first pivot part 15 increases, the probability of the second processing component shaking during rotation will increase, which is not conducive to the stable operation of the second processing component. In the long run, it will increase the risk of the first pivot part or the connection position between the first pivot part 15 and the second pivot part 16 breaking, resulting in a decrease in the service life of the structure.

[0112] Specifically, the transmission head 14 includes a boss 142, and the second pivot portion 16 is provided on a side of the boss 142 away from the output shaft. The second pivot portion 16 is a spline. By providing the boss 142, under the premise that the connection length between the meat cleaver assembly 13 and the second pivot portion 16 is constant, the second pivot portion 16 is provided on the boss 142, which is advantageous in shortening the length of the second pivot portion 16 compared to providing the second pivot portion 16 directly on the stopper 141. Figure 6 As shown, when the second pivot portion 16 is a spline, the second pivot portion 16 can be transmission-connected to the shaft hole 32 of the rotating shaft that drives the rolling cutter assembly 122 to rotate.

[0113] In one example, if Figure 11 As shown, the boss 142 is a columnar boss. In another example, the first pivot portion 15 is a cross-shaped structure, in which case the middle area of the cross-shaped structure can be used as the boss 142.

[0114] When processing food, since the food falls from the feeding port from top to bottom, when cutting the food, the cutting force on the food is strongest in the top area of the processing component, and the food is most likely to fly out into the gap between the processing component and the processing chamber, especially splashing into the gap between the second processing component 13 and the processing chamber 11, which causes the most serious problems and may directly cause the second processing component 13 to get stuck. Therefore, in this application, an inwardly protruding retaining rib 21 is provided on the inner side wall of the processing chamber, and the retaining rib 21 is set above the horizontal plane where the central axis of the output shaft is located, that is, it blocks the area where splashing is most likely to occur, so that the retaining rib cooperates with the first processing component 12 or the second processing component 13 to prevent food from splashing, and also ensures the cleanliness of the processing chamber. In addition, the retaining rib 21 can also straighten the processing component when radial shaking occurs, thereby improving the uniformity of food processing. In addition, the retaining rib 21 is a raised structure that is more three-dimensional than the smooth inner wall retaining rib of the processing chamber and has a smaller contact area with the food. When the cut vegetables splash onto the retaining rib, they can be rebounded quickly and promptly and fall back into the processing chamber, ensuring that the cut food can be fully discharged, reducing food waste, and avoiding some food splashing and sticking to the inner wall of the processing chamber, which increases the user's cleaning burden.

[0115] like Figure 2 or Figure 3 As shown, by using the retaining ribs 21 to straighten the drum 131 when it experiences radial wobbling, the amount of wobbling that the drum 131 may experience is reduced, thereby reducing collision noise. Furthermore, the drum 131 is promptly returned to its original position and remains coaxial with the output shaft of the drive assembly. In this way, the motion path formed by the drum during operation and rotation is approximately circular, and the thickness and size of the cut food are uniform. Furthermore, the retaining ribs 21 are raised structures, and compared to the smooth inner wall of the processing chamber 11, the retaining ribs 21 are more three-dimensional and have a smaller contact area with the food. When the cut chopped vegetables splash onto the retaining ribs 21, they can be quickly and promptly rebounded and fall back into the processing chamber 11, ensuring that the cut food can be fully discharged, reducing food waste, and preventing some food from splashing and sticking to the inner wall of the processing chamber 11, thereby increasing the user's cleaning burden.

[0116] Furthermore, under the premise that the second processing component 13 is a vegetable cutting knife component, since one end of the roller 131 is a fixed end and the other end is a cantilever end, radial shaking may occur during its rotation. On the one hand, it causes friction and wear with the inner wall of the processing chamber during shaking, generating noise. On the other hand, it causes the path of the vegetable cutting knife component to be tortuous during rotation, and the cut food is uneven. In order to solve the aforementioned problems of shaking noise and uneven cutting of food, the second processing component 13 is provided in this embodiment, including a cutting piece 132 and a bracket for mounting the cutting piece 132. Preferably, the bracket is a roller 131. One end of the roller 131 is engaged with the drive component to achieve the limit fixation of the roller 131, and the other end is suspended relative to the processing chamber 11. Reference Figure 5 The drum is provided with an anti-collision ring 1324 that protrudes radially outward relative to the cutting piece 132, and the anti-collision ring 1324 is clearance-matched with the retaining rib 21.

[0117] The use of a bumper ring 1324, which projects radially outward relative to the cutting element 132, ensures that if the cantilever end of the bracket deflects, the bumper ring 1324, rather than the cutting element 132, is the first to come into contact with the retaining rib 21. This prevents deformation of the cutting element 132, wear of the machining chamber 11, or even slippage of the cutting element 132 relative to the roller. The outwardly projecting bumper ring 1324 further minimizes the amount of deflection of the cantilever end of the roller relative to the machining chamber 11, further facilitating the retaining rib 21 to straighten the roller, thereby improving the overall rotary cutting stability and operating noise of the second machining assembly 13.

[0118] The retaining rib 21 may extend along the axial direction of the processing chamber 11, or the retaining rib 21 may extend along the radial direction of the processing chamber 11. When the retaining rib 21 extends axially, in one embodiment, the total length of the retaining rib 21 along the axial direction of the processing chamber 11 is not less than the total length of the cutting member 132 along the axial direction of the roller 131. The use of retaining ribs 21 that cover the length of the cutting member 132 can enhance the material blocking effect of the retaining rib 21, so that the food cut by the cutting member 132 can fall back into the processing chamber 11 after hitting the retaining rib 21, so that the food can contact the cutting member 132 again, and the food can be fully cut. The retaining rib 21 can be a continuous convex rib, and the total length of the retaining rib 21 is the length of the continuous convex rib. Alternatively, the retaining rib 21 includes multiple sections of sub-retaining ribs spaced apart along the axial direction, and the total length of the retaining rib 21 is the length of all sub-retaining ribs plus the length of all spacings.

[0119] The retaining rib 21 can be formed in one piece with the processing cavity 11, or it can be separately provided with the processing cavity 11 and fixedly connected. For example, the retaining rib 21 can be fixed to the inner wall of the processing cavity 11 by welding, bonding, etc.

[0120] In one embodiment, the retaining rib 21 is an elastic member, such as a silicone member, which can provide a certain buffer when the roller 131 contacts the retaining rib 21. The elastic force of the retaining rib 21 can help the roller 131 to quickly return to its original position and reduce wear on the roller 131.

[0121] In one embodiment, the gap between the retaining rib 21 and the outer wall of the roller 131 is in the range of 0.05 mm to 2 mm. Setting a reasonable gap range can avoid interference with the rotation of the roller 131 due to a too small gap, while also preventing the roller 131 from being unable to straighten due to a too large gap when the roller 131 sways slightly.

[0122] In one embodiment, the outer wall of the tool holder 121 is provided with a relief groove 22 that mates with the retaining rib 21. The relief groove 22 not only facilitates smooth installation of the tool holder 121 but also allows the rib to abut against the relief groove 22 in the event of wobbling, thereby restraining the tool holder 121 and preventing rotation that could affect the operation of the rolling cutter assembly 122. Furthermore, the relief groove 22, when mated with the retaining rib 21, also provides circumferential rotation prevention for the tool holder, further ensuring the reliability of the circumferential rotational connection between the tool holder and the machining chamber.

[0123] It should be noted that when the second processing component 13 is a vegetable cutting knife component, one end of the roller 131 is a fixed end and the other end is a cantilever end, and the processing chamber 11 is open on one side of the cantilever end. When the second processing component 13 is a dough kneading rod or an extrusion screw, the processing chamber 11 is covered with an end cover at the open position so that the two ends of the dough kneading rod or the extrusion screw are respectively connected to the drive component and the end cover.

[0124] The rolling cutter assembly 122 is generally used for slicing meat, which does not require a high rotational speed compared to cutting vegetables. To enable the first processing assembly 12 to cut meat at a low rotational speed, as a preferred embodiment, the first processing assembly 12 also includes a reduction gearbox 123 mounted on the tool holder 121. The drive assembly is connected to the rolling cutter assembly 122 via the reduction gearbox 123, and the rotational speed of the rolling cutter assembly 122 is lower than that of the second processing assembly 13. By integrating the reduction gearbox 123 with the tool holder 121, the requirements for the reduction gear structure of the machine base 10 can be reduced, ensuring that the rolling cutter assembly 122 can operate at a low rotational speed without relying on an external reduction gearbox. The second processing assembly 13 can output a relatively high rotational speed to achieve functions such as cutting vegetables, kneading noodles, and extruding noodles.

[0125] like Figure 6 As shown, the tool holder 121 is provided with a reduction box 123 located at one end of the rolling cutter group 122 and a handle 124 located at the other end of the rolling cutter group 122. The reduction box 123 can satisfy the rolling cutter group 122 to output a low speed for cutting meat, and the handle 124 is convenient for the user to take the tool holder 121 for installation, providing convenient operation.

[0126] To minimize the volume of the processing chamber 11 and simplify the structural configuration, and to achieve the adaptation of one processing chamber 11 and one feeding port 23 to two processing assemblies, a feeding port 23 is provided above the processing chamber 11 as a preferred embodiment. When the first processing assembly 12 and the second processing assembly 13 are installed in place, the rolling cutter assembly 122 and the second processing assembly 13 are exposed through the feeding port, that is, at least parts of the rolling cutter assembly 122 and the second processing assembly 13 are located within the range of the feeding port 23. When a single feeding port 23 is used, the first processing assembly 12 and the second processing assembly 13 are both installed with alignment with the same feeding port 23 as the reference. The installation positions of the first processing assembly 12 and the second processing assembly 13 are relatively small, which reduces the user's requirements for installing different processing assemblies, facilitates rapid switching between different processing assemblies, and ensures accurate installation positions.

[0127] It can be understood that in another embodiment, the drive assembly includes a motor and a two-stage reduction gearbox connected to the motor, the transmission head includes a first transmission head connected to the high-speed end of the two-stage reduction gearbox, and a second transmission head connected to the low-speed end of the two-stage reduction gearbox, the rolling cutter group is connected to the second transmission head, and the first transmission head and the second transmission head are nested inside and outside.

[0128] like Figure 9 As shown, the processing chamber 11 of this embodiment is a single-chamber structure. The first processing assembly 12 and the second processing assembly 13 are selectively installed in the processing chamber 11 to perform operations. The processing chamber 11 is provided with only one feeding port 23. By interchangeably using the first processing assembly 12 and the second processing assembly 13 in the processing chamber 11, the processing chamber 11 can be adapted to accommodate two different processing assemblies, making the processing chamber 11 more compact and the overall structure more compact, making it more suitable for home use. When the second processing assembly 13 is a vegetable cutting knife assembly, the axial length of the feeding port 23 preferably covers the length of the rolling cutter assembly 122 and the cutting element 132. In this way, after the material enters through the feeding port 23, it can immediately and fully contact the rolling cutter assembly 122 and the cutting element 132, which is conducive to improving cutting efficiency.

[0129] In order to reduce the probability of contact between different ingredients and avoid cross-flavoring, and to ensure reliable transmission of the rolling cutter group 122 when the rolling cutter group 122 is far away from the drive assembly, as a preferred embodiment, a first feeding port 24 and a second feeding port 25 are provided above the processing chamber 11, and the first feeding port 24 is arranged relative to the second feeding port 25 away from the output end of the drive assembly. The food processor includes a connecting rod 26, and the rolling cutter group 122 is connected to the output end of the drive assembly through the connecting rod 26. When the first processing assembly 12 is installed in place, the rolling cutter group 122 is aligned with the first feeding port 24. When the second processing assembly 13 is installed in place, the second processing assembly 13 is aligned with the second feeding port 25.

[0130] When two independent feeding ports are used, vegetables, meat, or other types of ingredients can be fed separately, which can reduce the probability of different ingredients coming into contact, thereby avoiding the occurrence of flavor contamination and ensuring the taste of the ingredients. The connecting rod 26 acts as an intermediate connection. Although the setting of the connecting rod 26 extends the transmission path, the connecting rod 26 itself is light and has no additional accessories. The load on the driving end is still very small. Therefore, when the load on the motor 29 is small, it is conducive to stable transmission to the rolling cutter group 122 through the connecting rod 26, ensuring the stability of the operation of the rolling cutter group 122.

[0131] In one embodiment, the first and second processing assemblies 12, 13 are installed in an offset arrangement within the processing chamber 11, corresponding to their respective feeding ports 23. This significantly reduces the volume of the processing chamber compared to prior art solutions in which the first and second processing assemblies must be completely offset. When the first processing assembly 12 is installed, it is positioned at the end of the processing chamber 11 away from the drive assembly. When the second processing assembly 13 is installed, it is positioned at the end of the processing chamber 11 closer to the drive assembly. The connecting rod 26 acts as an intermediate connection when the rolling cutter assembly 122 is located at a distance from the drive assembly, ensuring that the drive assembly can output power to the rolling cutter assembly 122 via the connecting rod 26.

[0132] In another embodiment, Figure 10 As shown, the processing chamber 11 includes two connected chambers. The first chamber 27 is set corresponding to the first feeding port 24, and the second chamber 28 is set corresponding to the second feeding port 25. When installing the processing components, they can be installed in the corresponding chambers.

[0133] In the above-mentioned embodiment, the alignment of the rolling cutter assembly 122 with the first feeding port 24 means that at least a portion of the rolling cutter assembly 122 is covered by the first feeding port 24, preferably, the rolling cutter assembly 122 is completely covered by the first feeding port 24, so that the food is immediately and fully contacted with the rolling cutter assembly 122 after feeding, thereby improving cutting efficiency. When the second processing assembly 13 is a vegetable cutting knife assembly, the alignment of the second processing assembly 13 with the second feeding port 25 means that at least a portion of the cutting member 132 is covered by the second feeding port 25, preferably, the cutting member 132 is completely covered by the second feeding port 25, so that the food is immediately and fully contacted with the cutting member 132 after feeding, thereby improving cutting efficiency.

[0134] In a preferred embodiment, the drive assembly includes a motor 29, which includes a first output shaft and a second output shaft, each extending into the processing chamber 11 and spaced vertically apart. One of the first and second output shafts is in driving connection with the rolling cutter assembly 122, and the other is in driving connection with the second processing assembly 13. Using different output shafts facilitates different speeds to meet the processing requirements of different processing assemblies for different ingredients. The two transmission paths, spaced vertically apart along the processing chamber 11, promote structural compactness and facilitate miniaturization of the entire machine, meeting the needs of miniaturization in home kitchens.

[0135] In a preferred embodiment, the second processing assembly 13 is any one of a vegetable cutting knife assembly, a dough kneading rod 18, or an extrusion screw 181. That is, while maintaining the same operating principle, the type of second processing assembly 13 can be flexibly configured to achieve multiple functions such as cutting vegetables, kneading dough, and extruding dough, allowing the food processor to be more than just vegetable and meat cutting functions, enriching the user's processing needs.

[0136] like Figure 3 As shown, the processing chamber 11 disclosed in the present application is a structure with a mounting opening 111 provided laterally. The mounting opening 111 is preferably arranged horizontally, so that the first processing assembly 12 and the second processing assembly 13 can be laterally installed or pulled out of the processing chamber 11 through the mounting opening 111, which is convenient for use. When the second processing assembly 13 is a kitchen knife assembly, the mounting opening 111 of the processing chamber 11 is not sealed. When the second processing assembly 13 is a dough kneading rod or an extrusion screw, after the dough kneading rod or the extrusion screw is installed in the processing chamber 11, an end cap needs to be added to the mounting opening 111 of the processing chamber 11 to secure the dough kneading rod or the extrusion screw.

[0137] Specifically, when the second processing assembly is a knife assembly, the knife assembly includes a roller and a plurality of interchangeable cutting members provided on the sidewall of the roller, and the processing chamber is open at a mounting opening on a side away from the transmission head. When the second processing assembly is a dough-mixing rod, the mounting opening of the processing chamber is covered with an end cap that blocks the mounting opening, and the end cap is provided with a limiting groove or a limiting protrusion for axially limiting the dough-mixing rod. When the second processing assembly is an extrusion screw, the mounting opening of the processing chamber is covered with an end cap that limits the axial position of the extrusion screw. Specifically, the end cap is provided with a limiting groove or a limiting protrusion for axially limiting the extrusion screw, and the end cap or the processing chamber is provided with an exit hole. When the dough-mixing rod is in operation, the dough-mixing rod rotates to form dough through the dough-mixing operation. When the extrusion screw is in operation, the extrusion screw rotates to push the dough to the corresponding dough-exiting structure (such as the die head assembly) for exiting the dough. The specific working principle can be referred to the existing technology and will not be described in detail here.

[0138] The processing chamber 11 of the present application is provided with a discharge port 30 at the bottom thereof, through which the processed food can fall into the receiving box 31 , thereby realizing food collection, freeing the user's hands, and improving the user experience.

[0139] In a preferred embodiment, a discharge port 30 is provided at the bottom of the processing chamber 11, and a food outlet is provided at the bottom of the first processing component. The food outlet is arranged in alignment with the discharge port 30, and the receiving box 31 is arranged below the discharge port 30 to hold the food processed by the first processing component. Since the first processing component relies on a rolling cutter group to cut food, the two groups of rolling cutters rotate relative to each other, so that the material falls from the food outlet and falls stably into the receiving box through the discharge port, eliminating the need for users to have a separate receiving plate or bowl. Of course, it is understandable that the receiving box can also be used to collect materials processed by the second processing component. For example, when the second processing component is a vegetable cutting knife component, the material is discharged from the mounting port of the processing chamber and falls into the receiving box; when the second processing component is an extrusion screw, the material is discharged from the outlet hole and falls into the receiving box.

[0140] The driving form of the first processing component 12 and the second processing component 13 can be either electric drive, such as the driving component includes a motor, and the motor drives the processing component to realize intelligent control, freeing the user's hands, or manual drive, such as the driving component includes a crank, and the user drives the processing component to work by rotating the crank, thereby enriching the user's experience.

[0141] The technical solutions protected by this utility model are not limited to the above-described embodiments. It should be noted that the combination of the technical solutions of any one embodiment with the technical solutions of one or more other embodiments falls within the scope of protection of this utility model. Although the utility model has been described in detail above using general descriptions and specific embodiments, it is obvious to those skilled in the art that modifications or improvements can be made based on this utility model. Therefore, such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
