Flour mixing component and extrusion module Technical Field

[0001] This application is a divisional application of Chinese invention patent application number 202411945800.0, filed on December 27, 2024, entitled "A cutting and mixing machine equipped with an extrusion module". This invention belongs to the field of household appliance technology, and specifically relates to a dough mixing component and an extrusion module. Background Technology

[0002] As people's living standards improve, busy work schedules are inevitable. In order to save time in the cooking and food preparation stage, various food preparation equipment has emerged. However, for Chinese cooking, the food preparation process is even more diverse.

[0003] Among them, pasta is a common food, such as noodles and flatbread. However, preparing pasta requires adding water to the flour to form dough flakes with the appropriate moisture content, stirring the dough flakes to create a more chewy texture, and then extruding the stirred dough flakes and dough into shapes.

[0004] Therefore, how to create a pasta product with a more chewy texture and extrusion shape is a problem that technicians must face. At the same time, how to integrate the extrusion module into the power platform is also a technical problem that technicians urgently need to solve. Summary of the Invention

[0005] To address the aforementioned technical problems, this application further improves the structure of the cutting and mixing machine to obtain a more chewy and elastic texture in pasta. One objective of this invention is to provide a dough mixing assembly, and another objective is to provide a corresponding dough extrusion module.

[0006] The specific technical solution is explained below:

[0007] A cutting and processing machine equipped with an extrusion module includes a power platform and an extrusion module disposed on the power platform;

[0008] The power platform includes a transmission structure and assembly components that cooperate with it;

[0009] The transmission structure includes: a phase-changing coupling, which includes a second output section and a third output section; the assembly component is disposed on the upper housing, and the assembly component includes: a snap-fit ​​groove, the outer end of which is an open end, and the inner end of which is provided with a third through hole to expose the third output section; the outer side of the inner end of the snap-fit ​​groove is provided with an assembly gap, and the assembly gap is provided with a second through hole to expose the second output section;

[0010] The extrusion module includes:

[0011] Water tank, dough mixing structure, and dough extrusion structure;

[0012] The dough extrusion structure includes an extrusion screw disposed in an extrusion channel below the dough mixing container, the extrusion screw having a drive end and an extrusion end disposed opposite to each other;

[0013] The extrusion channel is connected to the snap-fit ​​groove, and the driving end of the extrusion screw is driven to the third output part.

[0014] In the above technical solution, the extrusion module is connected to the power platform and driven by the drive end of the extrusion screw to the third output unit, thus realizing the assembly and use of the extrusion cutting machine.

[0015] Preferably, the transmission structure further includes a dual-output motor, which includes a first output and a coupling output.

[0016] The variable phase coupling provides power through the coupling output section;

[0017] The dual-output motor also includes a first output section;

[0018] The rotational speed corresponding to the first output unit is greater than the rotational speed corresponding to the second output unit, and the rotational speed corresponding to the second output unit is greater than the rotational speed corresponding to the third output unit;

[0019] The assembly components also include:

[0020] A snap-fit ​​boss has a length direction extending in a first direction, and a first through hole is provided on the snap-fit ​​boss to expose the first output part.

[0021] The snap-fit ​​groove has a length direction extending in the second direction;

[0022] The snap-fit ​​protrusion is located above the snap-fit ​​groove;

[0023] An assembly gap is provided between the inner end of the snap-fit ​​boss and the snap-fit ​​groove, and the assembly gap has a second through hole that exposes the second output part.

[0024] The first direction and the second direction are intersecting.

[0025] In the above technical solution, by combining a dual-output motor and a phase-changing coupling, the output units with three speed levels are integrated together, providing an operational basis for food preparation operations with various needs.

[0026] Specifically, in conjunction with the assembly components:

[0027] The snap-fit ​​boss provides the first type of assembly base. The cutting module can be snapped into the groove provided below and driven by the first output part to perform the corresponding cutting operation.

[0028] The snap-fit ​​groove provides a second assembly base. The cutting module can be snapped into the groove through the strip-shaped snap-fit ​​tenon set on the side or bottom, and the corresponding cutting operation is driven by the third output part.

[0029] The assembly interval separates the snap-fit ​​boss and the snap-fit ​​groove, and also separates the first through hole and the third through hole, which facilitates the configuration of the transmission structure. At this time, the assembly interval serves as the third type of assembly base and can drive the corresponding cutting and fitting operation through the second through hole as the source of power.

[0030] The snap-fit ​​boss is located above the snap-fit ​​groove. At the same time, the snap-fit ​​boss protrudes upward and the snap-fit ​​groove is recessed downward. The upward and downward concave and convex directions make the two staggered in the vertical direction more. The first direction and the second direction intersect each other, which makes it easier to arrange the two assembly bases in the horizontal direction, making the integrated setup more reasonable.

[0031] The assembly component described in this invention provides at least two assembly structures to accommodate the integrated setup of different assembly modules.

[0032] Preferably, the inside of the snap-fit ​​boss is provided with a motor snap-fit ​​groove, the opening of the motor snap-fit ​​groove faces downward, and the side wall of the motor snap-fit ​​groove engages and limits the upper part of the dual output motor;

[0033] More preferably, the first output part is disposed on one side of the dual-output motor, the third output part is disposed at the end of the phase-changing coupling away from the dual-output motor, and the second output part is disposed above the third output part; more preferably, the inner end of the snap-fit ​​groove is provided with a coupling limiting wall, and the coupling limiting wall abuts against and snaps against the side of the phase-changing coupling where the third output part is located.

[0034] In other words, the snap-fit ​​boss and snap-fit ​​groove not only facilitate the integrated assembly of various cutting and fitting modules, but also limit the transmission structure through their own structure, preventing it from vibrating and jumping, and making the assembly of the transmission structure more stable.

[0035] Preferably, the output direction of the first output unit is vertically upward, the output direction of the second output unit is vertically upward, and the output direction of the third output unit is horizontal.

[0036] The opening direction of the first through hole is vertically upward, the opening direction of the third through hole is horizontal, and the opening direction of the second through hole is vertically upward.

[0037] Preferably, the first through hole is disposed at one end of the snap-fit ​​protrusion extending along the length direction, and the third through hole is disposed in the middle region of the inner end;

[0038] The location and orientation of the first through hole, the second through hole, and the third through hole are used to adapt to the output position and output direction of the transmission structure.

[0039] More preferably, a gap is provided between the first output section and the second output section to avoid the snap-fit ​​structure. This arrangement allows the food preparation module powered by the first output section to have space for snap-fit ​​installation, preventing the second output section from causing installation obstruction.

[0040] More preferably, the second output section and the third output section have a coplanar rotation output axis. This arrangement allows the second output section and the third output section to jointly serve as the power input section of the food preparation module, which facilitates the internal structural design of the food preparation module.

[0041] The food preparation module, such as the dough kneading and extrusion module, has a second output unit responsible for the power input for kneading and a third output unit responsible for the power input for extrusion. Since the rotation output shafts of the second and third output units are coplanar, the dough kneading operation can be directly followed by the extrusion operation.

[0042] Preferably, the output power of the first output unit acts at least on the module that crushes the ingredients.

[0043] Preferably, the output power of the second output unit acts at least on the module for cutting vegetables or kneading dough.

[0044] Preferably, the output power of the third output unit acts at least on the module for cutting meat or extruding noodles.

[0045] Preferably, the first output section outputs power through a spline structure.

[0046] Preferably, the coupling output section obtains the output direction of the second output section and the third output section through a bevel gear connection structure, and adjusts the rotational speed of the second output section and the third output section respectively.

[0047] Preferably, the first direction and the second direction are perpendicular to each other.

[0048] Preferably, it also includes a support structure that serves as both a platform and a trough, the support structure comprising:

[0049] The upper shell has an assembly structure for the food preparation module formed on its surface and a transmission structure for power output inside.

[0050] The lower housing is used to support the upper housing and the positioning handle, and forms a placement space for placing containers, the placement space being located below the upper housing;

[0051] The aforementioned positioning handle is telescopically positioned between the upper housing and the lower housing, and its positioning is achieved in both hidden and locked states through a positioning structure.

[0052] The support structure includes a retractable support plate disposed at the lower end of the lower housing. When the support plate is extended, it is exposed below the placement space and when it is retracted, it is hidden at the lower end face of the lower housing.

[0053] In the above technical solution, a placement space is formed below the upper shell to accommodate bowls or basins, thereby saving kitchen countertop space. However, after the placement space is formed, the upper shell of the power platform still occupies a large space and has a certain weight because it needs to cover the power mechanism, etc. This structure makes the power platform top-heavy, unstable, and even easy to tip over. Therefore, a support structure is also provided. The support plate extending from the support structure supports the power platform and makes it more stable.

[0054] In addition, depending on whether it is to work in the water tank, the positioning handle can be in a hidden state and a locked state. When it is in the hidden state, the positioning handle is retracted and does not take up extra space. When it is in the locked state, the positioning handle is locked against the inner wall of the water tank to fix the position of the power platform in the water tank and prevent it from moving. At the same time, the positioning handle itself can also be used as a handle to lift the power platform, making it easy to move its position.

[0055] Furthermore, the positioning handle itself is located above the placement space, making the center of the power platform more upward, which makes the existence of the support structure even more necessary; when the positioning handle extends and locks in the water tank, the support plate in the support structure can be retracted and hidden in the lower end face of the lower shell to prevent the support plate from taking up extra space.

[0056] Preferably, the positioning structure includes a positioning buckle and a group of positioning holes;

[0057] The positioning hole group includes a plurality of positioning holes, which are spaced apart on the side wall of the positioning handle along the extension and retraction direction of the positioning handle. The positioning buckle is inserted into the corresponding positioning hole to achieve positioning.

[0058] Preferably, the positioning hole group consists of hidden positioning holes and locking positioning holes;

[0059] The hidden positioning hole is located near the end of the positioning handle that is engaged with the water tank.

[0060] The positioning hole is located at the end of the water tank that is away from the positioning handle.

[0061] Preferably, the positioning buckle is positioned by adjusting the through hole and then inserting it into the corresponding positioning hole.

[0062] Preferably, the adjustment through hole is partially formed on the upper housing and partially formed on the lower housing, and the upper housing and the lower housing are joined together to form the adjustment through hole.

[0063] Preferably, when in the locking position, the width of the power platform in the telescopic direction of the positioning handle is adapted to a span within the water tank, which is typically the width of the water tank.

[0064] Preferably, the feature is that, when in the hidden state, the inner contour of the positioning handle fits snugly against the power platform.

[0065] Preferably, the positioning handle is engaged with the side wall of the water tank by means of the handle portion, and the outer layer of the handle portion is provided with an elastic surface layer so as to fit more tightly against the inner wall of the water tank.

[0066] Preferably, each side of the positioning handle has a side arm, and each side arm is provided with a counterweight at the end away from the handle portion; more preferably, when the positioning handle is in the locked state, the counterweight is disposed inside the space covered by the upper shell and / or the lower shell.

[0067] In the above technical solution, the counterweight block installed at the end of the side arm can optimize several problems existing in the power platform:

[0068] ① When the positioning handle is in the hidden state, the power platform is applied to the table. The counterweight is located inside the shell on the side away from the placement space. This side is exactly opposite to the protruding end of the upper shell, that is, the protruding part above the placement space. Originally, the protruding end of the upper shell caused the power platform to be prone to tipping over. However, the presence and position of the counterweight greatly balance the center of gravity tilt problem caused by the protruding end, thus greatly improving the risk of the above-mentioned hidden danger.

[0069] ② When the positioning handle is in the locked position, the distance between the extended parts of the positioning handle is relatively long. In structures with a long extension, the end where the handle is located tends to sink, causing the positioning handle to easily tilt towards the end where the handle is located, resulting in unstable locking with the water tank or even locking failure. However, by setting a counterweight and keeping the counterweight within the internal space of the shell, with the side arm using the edge of the shell as a fulcrum, the counterweight balances the weight distribution of the positioning handle itself in the locked position, thus reducing or even eliminating the tendency of the positioning handle to tilt towards the end where the handle is located, thereby improving the risk of locking failure.

[0070] Preferably, the positioning buckle consists of a positioning cap that is easy to hold and a positioning protrusion that is inserted into the positioning hole. During operation, the user holds the positioning cap and inserts the positioning protrusion into the positioning hole.

[0071] Preferably, the support plate is provided with slide rails on both sides extending along its extension and retraction direction, and the support plate moves along the slide rails.

[0072] Preferably, the slide rail is provided with a first stop, which limits the extension range of the support baffle and ensures that the support baffle is at least partially located at the lower end face of the lower housing when it is restricted.

[0073] After the support plate extends, the portion that is confined in the slide rail engages with the slide rail, providing support for the support plate and ensuring that the force of the power platform's gravity acts primarily on the plane of the support plate, rather than on the ends of the support plate, making the power platform more stable.

[0074] More preferably, a second stop is provided on the side of the support plate where the first stop is located, and the first stop restricts the extension range of the support plate by abutting against the second stop.

[0075] Preferably, the first or second stop is an elastic block.

[0076] Preferably, the thickness of the support plate is less than 5 mm.

[0077] Preferably, the support plate is a rigid flat plate formed in one piece.

[0078] More preferably, the corners of the outer contour of the support plate have arc-shaped edges.

[0079] Preferably, when the support plate is extended to its maximum extent and placed on the platform, the center of gravity of the cutting and mixing machine power platform is projected onto the support plate in the vertical direction.

[0080] Preferably, the water tank is connected to the dough-mixing cover above the dough-mixing container; the dough-stirring structure is disposed inside the dough-mixing container for stirring the dough flakes; the dough-stirring extrusion structure is disposed at the lower part of the dough-mixing container for extruding the stirred dough flakes.

[0081] in:

[0082] The dough stirring structure includes a stirring rod, which is drivenly connected to the second output unit;

[0083] The extrusion structure also includes an extrusion outlet located at the extrusion end.

[0084] In the above technical solution, the stirring surface is stirred by driving the stirring rod and the second output unit.

[0085] Preferably, the water tank slot is engaged with the lower end of the water tank.

[0086] Preferably, the water tank outlet is connected to the dough mixing inlet via a check valve. In this case, the check valve is opened to a flow-through state by the dough mixing inlet. Before the check valve is connected to the dough mixing inlet, it is in a stop-flow state, and water in the water tank will not flow out. After the check valve is connected to the dough mixing inlet, it is in a flow-through state, and water in the water tank is added to the dough mixing container. More preferably, the dough mixing inlet is a protruding inlet pipe. The protruding inlet pipe is inserted into the check valve to open it to a flow-through state. In this case, the protruding inlet pipe also plays an auxiliary positioning role, making the water tank installation more secure.

[0087] Preferably, the water tank slot is a groove adapted to the shape of the bottom of the water tank; more preferably, the dough inlet is located at one end of the bottom of the water tank slot, which can prevent the water tank from being installed backwards;

[0088] Preferably, a strip-shaped first portable protrusion is provided in the middle of the dough cover; more preferably, the water tank slot is provided on one side of the first portable protrusion.

[0089] The first portable protrusion makes it easy for users to hold the kneading container by hand, while the placement of the water tank slot facilitates the utilization and arrangement of the space above the kneading lid.

[0090] Preferably, the water tank is provided with a water tank cover, and the water tank cover is provided with a strip-shaped second portable protrusion, so that the user can hold the water tank by hand.

[0091] Preferably, the water tank is a cylindrical body, and the cross-section of the cylindrical body has a shape that matches the inner contour of the water tank slot. In this case, the water tank is only located in the upper part of the water tank slot and does not occupy additional space.

[0092] Preferably, the lower part of both the first portable protrusion and the second portable protrusion is provided with a gradually expanding base structure, which can form a basis for handheld use.

[0093] Preferably, the stirring rod includes a rod body, which is vertically arranged in the working state. The two ends of the rod body are respectively provided with a drive connection part and a follower connection part. A pre-stirring arm, an auxiliary stirring arm and a main stirring arm are arranged sequentially from top to bottom on the rod body.

[0094] The dough flake return section on the main mixing arm can scrape the dough flakes scattered on the inner wall of the mixing container and guide them to the dough flake extrusion area. Then, the auxiliary mixing arm will perform secondary mixing on the guided dough flakes in the dough flake extrusion area to improve the chewy texture of the dough flakes.

[0095] Preferably, the auxiliary stirring arm has a dough extrusion area formed at the end away from the rod; the main stirring arm has a dough return baffle that protrudes toward the dough extrusion area at the end away from the rod; when the rod rotates, the outer contour of the dough return baffle forms a circular trajectory, which is adapted to the inner wall contour of the dough container.

[0096] The dough flake return section on the main mixing arm can scrape the dough flakes scattered on the inner wall of the mixing container and guide them to the dough flake extrusion area. Then, the auxiliary mixing arm will perform secondary mixing on the guided dough flakes in the dough flake extrusion area to improve the chewy texture of the dough flakes.

[0097] Preferably, the distance between the pre-stirring arm and the rod body is greater than the distance between the auxiliary stirring arm and the rod body. The end of the stirring arm has a stronger stirring effect and a more thorough stirring action. Therefore, this design allows the pre-stirring arm to stir the flour flakes within a larger rotation range. The stirring area of ​​the auxiliary stirring arm is different from that of the pre-stirring arm, so that the flour flakes in different areas are thoroughly stirred.

[0098] Preferably, the distance between the main stirring arm and the rod body is greater than the distance between the auxiliary stirring arm and the rod body. Similarly, the main stirring arm has a larger stirring range and should cooperate with the scraping action of the flour floc return section to facilitate the formation of the flour floc extrusion area. The stirring range of the main stirring arm should be as large as possible, usually greater than the stirring range of the pre-stirring arm.

[0099] Preferably, the pre-stirring arm and the auxiliary stirring arm extend in opposite directions from the rod body to reduce mutual interference between them and to distribute them as evenly as possible within the dough mixing container, minimizing the probability of dough clumps not being stirred.

[0100] Preferably, in the working state, the upper surface of the auxiliary stirring arm is provided with a first guide side, the first guide side having a downwardly extending inclined surface from the extension direction of the rod body; the upper surface of the pre-stirring arm is provided with a second guide side, the second guide side having a downwardly extending inclined surface from the extension direction of the rod body.

[0101] Under the action of centrifugal force, the first and second guide sides cause the dough flakes to move outward and downward, making it easier for them to be scraped up by the dough flake return section for secondary stirring.

[0102] Preferably, the auxiliary stirring arm and the main stirring arm are located on the same side of the rod body, so that the auxiliary stirring arm acts on the dough flakes scraped up by the dough flake return baffle at the first moment.

[0103] Preferably, in the working state, the upper surface of the main stirring arm is provided with a third guide side, the third guide side having a downwardly extending inclined surface along the direction pointing towards the rod body; the side of the floc return baffle near the rod body is provided with a fourth guide side, the fourth guide side having a downwardly extending inclined surface along the direction pointing towards the rod body.

[0104] The third and fourth guiding sides are used to guide the dough flakes after secondary mixing to be output further downwards.

[0105] Preferably, the top view projection relationship of the pre-stirring arm, the auxiliary stirring arm, and the main stirring arm is as follows:

[0106] The auxiliary stirring arm and the main stirring arm have projection areas that extend in the same direction and at least partially overlap.

[0107] The pre-stirring arm and the auxiliary stirring arm have projected areas with opposite directions of extension;

[0108] The pre-stirring arm and the main stirring arm have projected areas with opposite directions of extension.

[0109] In a further preferred embodiment, the water inlet for kneading is positioned so that the dripping point is located on the inner wall of the kneading container. This arrangement allows the flour to first form flocs on the inner wall of the kneading container under the guidance of the first and second guide sides of the stirring rod, combined with the centrifugal force of the flour. These flocs are then scraped off by the floc return section and guided to the floc extrusion area, where the auxiliary stirring arm performs secondary kneading. This creates a floc formation-extrusion-secondary kneading path, which improves the kneading efficiency and also produces a chewy and delicious pasta.

[0110] Preferably, the extrusion structure further includes an extrusion cover fixed to one end of the extrusion channel, the extrusion cover being at least partially fitted onto the extrusion end, the extrusion cover having a space for the extrusion screw to rotate inside, and the extrusion outlet being disposed on the surface of the extrusion cover.

[0111] It also includes an extrusion die head, which is detachably covered at the extrusion outlet. The extrusion die head has a dough extrusion section, and different shapes of pasta can be extruded by replacing different dough extrusion sections - corresponding to different shaped dough extrusion holes.

[0112] Preferably, the extrusion cover is provided with a first limiting ring at one end adjacent to the dough mixing container; it also includes an extrusion fixing member, which is provided with an outer cover through hole, a second limiting ring and a fixing structure. The outer cover through hole is sleeved on the extrusion cover, and the fixing structure fixes the extrusion fixing member to the dough mixing container. At least partially overlapping snap-fit ​​portions are formed between the first limiting ring and the second limiting ring, and another snap-fit ​​portion is formed on the dough mixing container that contacts the first limiting ring. The two snap-fit ​​portions cause the first limiting ring to snap between the extrusion fixing member and the dough mixing container.

[0113] Preferably, the extruded outer cover includes a first tubular member, the first limiting ring is formed at one end of the first tubular member, and the other end of the first tubular member is closed;

[0114] The extrusion outlet is located on the first tubular component;

[0115] The first tubular component is preferably a round tube.

[0116] More preferably, the extrusion outlet is located at the lower end of the first tubular member and faces downwards, so that it can be extruded by the weight of the surface itself.

[0117] Preferably, the extrusion fixing member has a second tubular member, the second limiting ring is opened at one end of the second tubular member, and the fixing structure is disposed at the other end of the second tubular member;

[0118] The inner contour of the second limiting ring surrounds and forms the outer cover through hole.

[0119] The extrusion fastener is also tubular in shape to fit the tubular extrusion cover.

[0120] More preferably, the fixing structure is a threaded structure consisting of an internal thread on the inner wall of the second tubular component and an external thread on the dough container, wherein the snap-fit ​​portion between the dough container and the first limiting ring is located at the end of the external thread.

[0121] Preferably, the extrusion die covers the extrusion outlet from the inner wall of the first tubular member, making it less likely to fall out.

[0122] Preferably, the extrusion die is a sheet-like component and has a shape that matches the inner wall contour of the first tubular component.

[0123] More preferably, the first limiting ring includes a limiting portion protruding into the first tubular member.

[0124] More preferably, the extrusion die has a limiting length that matches the distance between the limiting portion and the closed end of the first tubular member.

[0125] The limiting part is used to form the basis of the limiting extrusion die head. The extrusion die head is limited between the limiting part and the closed end, without the need for additional positioning structure.

[0126] In summary, the technical solution described in this invention has the following main beneficial effects:

[0127] Compared with the prior art, the present invention realizes the assembly and use of the extrusion and cutting machine by connecting the extrusion module to the power platform, and by driving the stirring rod to the second output part and the driving end of the extrusion screw to the third output part.

[0128] Meanwhile, the power platform integrates the output units of three different speed levels, providing an operational basis for food preparation operations such as crushing, kneading and extruding dough, cutting vegetables, and cutting meat. The assembly components offer a variety of assembly structures to adapt to the integration settings of different assembly modules and have a reasonable assembly integration layout.

[0129] The technical solution of this invention saves kitchen countertop space by placing a bowl or basin in the space, and provides support for the power platform through the support plate extending from the support structure, making it more stable.

[0130] In addition, depending on whether the operation is to be carried out in the water tank, the positioning handle can be in a hidden state or a locked state. When hidden, it does not take up extra space; when locked, it can fix the position of the power platform in the water tank and prevent it from moving. At the same time, the positioning handle itself also makes it easier to move the position of the power platform.

[0131] The extrusion module disclosed in this invention provides a stable and detachable water tank assembly structure, which can be used in conjunction with the dough mixing structure to obtain more elastic dough flakes, and the dough flakes can be extruded through the dough extrusion structure. Different shapes of pasta can be extruded by changing the extrusion die head with different extrusion hole shapes.

[0132] Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the detailed implementation. Attached Figure Description

[0157] The present invention will be further explained in conjunction with the embodiments:

[0158] The core technical problem faced by the technical solution of this application embodiment stems from the inventor's accurate understanding of the prior art. Therefore, how to assemble and use the extrusion module and the power platform is a technical problem that the inventor urgently needs to solve.

[0159] It should be noted that the embodiments do not constitute a limitation on the scope of protection of the claims of this invention. All technical solutions that can be reasonably expected by those skilled in the art based on the technical concepts provided / proved by the embodiments should be covered within the scope of protection of the claims of this invention.

[0160] The specific implementation examples are detailed below:

[0161] Please refer to Figures 1-2 and 6-7. A cutting and mixing machine equipped with an extrusion module consists of a power platform 1 and an extrusion module 2, wherein:

[0162] The power platform 1 is equipped with a transmission structure and matching assembly components;

[0163] The transmission structure includes a dual-output motor 1.1, which consists of a first output 1.11 and a coupling output 1.12; it also includes a phase-changing coupling 1.2, which provides power through the coupling output 1.12, and the phase-changing coupling 1.2 includes a second output 1.21 and a third output 1.22.

[0164] The assembly component is mounted on the upper housing 1.3. The assembly component is provided with a snap-fit ​​groove 1.32. The outer end of the snap-fit ​​groove 1.32 is an open end, and the inner end is provided with a third through hole 1.321 that exposes the third output part 1.22. The outer side of the inner end of the snap-fit ​​groove 1.32 is provided with an assembly gap 1.33. The assembly gap 1.33 is provided with a second through hole 1.331 that exposes the second output part 1.21.

[0165] The first output part 1.11 is located on one side of the dual output motor 1.1, the third output part 1.22 is located at the end of the phase coupling 1.2 away from the dual output motor 1.1, and the second output part 1.21 is located above the third output part 1.22.

[0166] Extrusion module 2 includes:

[0167] Water tank 2.8, dough mixing structure and dough extrusion structure;

[0168] Water tank 2.8 is connected to the dough-mixing cover 2.7 above the dough-mixing container 2.5; a dough-stirring structure is located inside the dough-mixing container 2.5 for stirring dough flakes; a dough-stirring extrusion structure is located at the bottom of the dough-mixing container 2.5 for extruding the stirred dough flakes; specifically,

[0169] The dough-making cover 2.7 is provided with a water tank slot 2.71, the water tank 2.8 is snapped into the water tank slot 2.71, the water tank slot 2.71 is provided with a dough-making water inlet 2.72, and the lower end of the water tank 2.8 has a water tank outlet that connects to the dough-making water inlet 2.72 after snapping.

[0170] The dough mixing structure includes a mixing rod 2.6;

[0171] The dough extrusion structure includes an extrusion screw 2.1 disposed in an extrusion channel below the dough container 2.5. The extrusion screw 2.1 has a drive end 2.11 and an extrusion end 2.12 disposed opposite to each other, and also includes an extrusion outlet 2.21 disposed at the extrusion end 2.12.

[0172] The stirring rod 2.6 of the extrusion module 2 is driven to be connected to the second output unit 1.21;

[0173] The extrusion channel is connected within the snap-fit ​​groove 1.32, and the drive end 2.11 of the extrusion screw 2.1 of the extrusion module 2 is driven to connect with the third output part 1.22.

[0174] In the technical solution of this embodiment: the extrusion module 2 is connected to the power platform 1 by snapping, and the extrusion screw 2.6 is connected to the second output part 1.21 by driving the stirring rod 2.6 and the third output part 1.22 by driving the extrusion screw 2.1's driving end 2.11 to the third output part 1.22 to achieve the assembly and use of the extrusion cutting machine.

[0175] In a preferred embodiment, referring to Figures 2-3, the assembly component further includes a snap-fit ​​boss 1.31, wherein the length extension direction of the snap-fit ​​boss 1.31 is perpendicular to the length extension direction of the snap-fit ​​groove 1.32, so as to integrate the two into a rectangular component as much as possible. At the same time, the snap-fit ​​boss 1.31 is positioned above the snap-fit ​​groove 1.32 so that the two are staggered in the vertical direction, making the layout more suitable for the transmission structure and facilitating the assembly of the cutting module.

[0176] Specifically, the snap-fit ​​boss 1.31 has a first through hole 1.311 that exposes the first output part 1.11. The first through hole 1.311 is located at one end of the snap-fit ​​boss 1.31 that extends along the length direction and has its opening direction vertically upward.

[0177] The outer end of the snap-fit ​​groove 1.32 is an open end, and the inner end is provided with a third through hole 1.321 that exposes the third output part 1.22. The third through hole 1.321 is located in the middle area of ​​the inner end and the opening direction is horizontal.

[0178] The technical solution of this embodiment provides two assembly structures to adapt to the integration settings of different assembly modules:

[0179] The snap-fit ​​boss 1.31 provides the first type of assembly base, and the cutting module can be snap-fitted and assembled with it through the groove provided below, and the corresponding cutting operation is driven by the first output part 1.11.

[0180] The snap-fit ​​groove 1.32 provides a second assembly base, and the cutting module can be snapped and assembled with it through the strip-shaped snap-fit ​​provided on the side or below, and the corresponding cutting operation is driven by the third output part 1.22.

[0181] The location and orientation of the first through hole 1.311 and the third through hole 1.321 are used to adapt to the output position and output direction of the transmission structure.

[0182] In this embodiment, an assembly gap 1.33 is provided between the inner ends of the snap-fit ​​boss 1.31 and the snap-fit ​​groove 1.32. The assembly gap 1.33 has a second through hole 1.331 that exposes the second output part 1.21. The opening direction of the second through hole 1.331 is vertically upward.

[0183] The technical solution of this embodiment separates the snap-fit ​​boss 1.31 and the snap-fit ​​groove 1.32, and also separates the first through hole 1.311 and the third through hole 1.321, which facilitates the configuration of the transmission structure. At the same time, the assembly interval 1.33 serves as a third type of assembly base, and the corresponding cutting and fitting operation can be driven through the second through hole 1.331 as the source of power drive.

[0184] Please continue to refer to Figure 3. The embodiment also includes a three-way output transmission structure used in conjunction with the above-mentioned assembly components: wherein, the three-way output transmission structure is based on a dual-output motor 1.1 and a phase-changing coupling 1.2 as core components. The dual-output motor 1.1 is a high-torque worm gear reducer motor with two output shafts. The two output shafts are paired with two output parts. One output part is a first output part 1.11 with the output direction vertically upward, and the other output part is a coupling output part 1.12 with the output direction horizontal. The first output part 1.11 outputs power through a spline structure.

[0185] Power is provided by the aforementioned coupling output section 1.12. The input end of the variable coupling 1.2 is connected to the coupling output section 1.12. The variable coupling 1.2 also includes two output sections. One output section is a second output section 1.21 with the output direction vertically upward, and the other output section is a third output section 1.22 with the output direction horizontal. The coupling output section 1.12 obtains the different output directions of the second output section 1.21 and the third output section 1.22 through a bevel gear connection structure, and adjusts the speeds corresponding to the second output section 1.21 and the third output section 1.22 respectively.

[0186] In the technical solution of this embodiment, in order to adapt to the needs of different cutting modules, the first output unit 1.11, the second output unit 1.21 and the third output unit 1.22 are set to have different output speeds. Specifically, the speed corresponding to the first output unit 1.11 is greater than the speed corresponding to the second output unit 1.21, and the speed corresponding to the second output unit 1.21 is greater than the speed corresponding to the third output unit 1.22.

[0187] By combining a motor with two output sections and a phase-changing coupling, the output sections with three speed levels are integrated, providing an operational basis for food preparation operations with various needs.

[0188] For example, as configured in the embodiment:

[0189] The first output section 1.11 has the fastest rotation speed, and its output power can be used for the grinding module to grind the ingredients. The grinding module has a groove below it that matches and engages with the locking boss 1.31, and a transmission structure that matches the position of the first through hole 1.311 and is connected to the first output section 1.11.

[0190] The second output section 1.21 has a medium rotation speed, and its output power can be used for cutting vegetables or kneading dough. The corresponding module is mounted on the assembly interval 1.33 and is provided with a transmission structure that matches the position of the second through hole 1.331 and is connected to the second output section 1.21.

[0191] The third output unit 1.22 has the slowest output speed and can be used to drive the extrusion module. The extrusion module is assembled by snapping into the snap-fit ​​groove 1.32 through a strip-shaped tenon. The strip-shaped tenon is provided with a transmission structure that matches the position of the third through hole 1.321 and is connected to the third output unit 1.22.

[0192] In a preferred embodiment, a gap is provided between the first output section 1.11 and the second output section 1.21 to avoid interference with the snap-fit ​​structure. In this case, when the shredding module is snap-fitted onto the first output section, interference from the second output section 1.21 on its snap-fit ​​structure can be avoided.

[0193] In a preferred embodiment, the second output section 1.21 and the third output section 1.22 have coplanar rotational output axes. In this embodiment, the second output section 1.21 and the third output section 1.22 can jointly serve as the power input part of the dough kneading and extruding two-in-one food preparation module, which facilitates the internal structural design of the module. Specifically, the second output section 1.21 is responsible for the power input of dough kneading, and the third output section 1.22 is responsible for the power input of dough extrusion. Since the rotational output axes of the second output section 1.21 and the third output section 1.22 are coplanar, the dough kneading operation can be directly followed by the dough extrusion operation.

[0194] Please refer to Figures 2-5 again. In the preferred embodiment, the power platform includes an outer shell, which is composed of an upper shell 1.3 and a lower shell 1.4 joined together. It also includes a positioning handle 1.5 and a support structure 1.6, wherein:

[0195] The upper shell 1.3 and lower shell 1.4 can be made of various common materials, not limited to various plastics, alloys and other materials. The upper shell 1.3 has an assembly structure for the cutting module formed on its surface and a transmission structure for power output inside. Therefore, the upper shell 1.3 occupies a large volume. The lower shell 1.4 is used to support the upper shell 1.3. The lower shell 1.4 has a placement space 1.41 for placing containers. The placement space 1.41 is located below the upper shell 1.3 and is used to hold bowls or basins to conveniently receive prepared dishes. Therefore, the lower shell 1.4 is relatively small in volume. The power platform itself is in a top-heavy state. Whether placed in a sink or on a platform, it is prone to displacement or even tipping over if not secured, causing trouble for food preparation.

[0196] Therefore, this embodiment provides a positioning handle 1.5 and a support structure 1.6 as described above, to correspond to the placement of the power platform in the water tank and on the platform, respectively, so as to prevent it from being stable and tipping over.

[0197] Specifically:

[0198] The positioning handle 1.5 is telescopically positioned between the upper housing 1.3 and the lower housing 1.4, and its positioning structure enables it to be in a hidden state and a locked state.

[0199] In the above technical solution of this embodiment, depending on whether it needs to work in the water tank, the positioning handle 1.5 can be in a hidden state and a locked state respectively. When it is in the hidden state, the positioning handle 1.5 is retracted and does not occupy additional space; when it is in the locked state, the positioning handle 1.5 is locked with the inner wall of the water tank to fix the position of the power platform in the water tank and prevent it from moving. At the same time, the positioning handle 1.5 itself can also be used as a handle to lift the power platform, making it convenient to move its position.

[0200] Specifically, when in the hidden state, the inner contour of the positioning handle 1.5 fits snugly against the power platform; when in the locked state, the width of the power platform in the extension direction of the positioning handle 1.5 is consistent with the width inside the water tank.

[0201] The positioning structure in the above embodiments includes a positioning buckle 1.51 and a positioning hole group 1.52;

[0202] The positioning hole group 1.52 consists of a hidden positioning hole 1.521 and a locking positioning hole 1.522. The hidden positioning hole 1.521 is located near the end of the positioning handle 1.5 that is locked to the water tank, and the locking positioning hole 1.522 is located away from the end of the positioning handle 1.5 that is locked to the water tank. The positioning buckle 1.51 is inserted into the corresponding positioning hole to achieve positioning.

[0203] Specifically, the positioning buckle 1.51 consists of a positioning cap that is easy to hold and a positioning protrusion that is inserted into the positioning hole. During operation, the user holds the positioning cap and inserts the positioning protrusion into the positioning hole.

[0204] Before insertion, the positioning buckle 1.51 is first positioned by adjusting the through hole and then inserting into the corresponding positioning hole. The adjusting through hole is partially opened on the upper shell 1.3 and partially opened on the lower shell 1.4. The upper shell 1.3 and the lower shell 1.4 are joined together to form the adjusting through hole.

[0205] The support structure 1.6 includes a retractable support plate 1.61 located at the lower end of the lower housing 1.4. When the support plate 1.61 is extended, it is located below the placement space 1.41. When the support plate 1.61 is retracted, it is hidden at the lower end face of the lower housing 1.4.

[0206] In this embodiment, the support plate 1.61 is a rigid rectangular plate formed in one piece, with arc-shaped edges at the corners of its outer contour and a thickness of less than 5mm.

[0207] Specifically, the support plate 1.61 is provided with slide rails 1.62 extending along its extension direction on both sides. The support plate 1.61 performs the aforementioned extension and retraction movement along the slide rails 1.62. A first stop 1.63 is provided in the slide rails 1.62. A second stop 1.64 is provided on the side of the support plate 1.61 where the first stop 1.63 is located. The first stop 1.63 restricts the extension range of the support plate 1.61 by abutting against the second stop 1.64, and ensures that the support plate 1.61 is at least partially located on the lower end face of the lower housing 1.4 when it is restricted.

[0208] In this embodiment, a placement space 1.41 is formed below the upper shell 1.3 to accommodate bowls or basins, thereby saving kitchen countertop space. At the same time, after the placement space 1.41 is formed, the upper shell 1.3 of the power platform still occupies a large space and has a certain weight because it needs to cover the power mechanism, etc. This structure makes the power platform top-heavy, unstable, and even prone to tipping over. Therefore, the embodiment also provides a support structure 1.6, and the support plate 1.61 extending from the support structure 1.6 provides support for the power platform, making it more stable.

[0209] After the support plate 1.61 extends, the part that is confined in the slide rail 1.62 is engaged in the slide rail 1.62, providing support for the support plate 1.61 and making the force of the power platform mainly act on the plane of the support plate 1.61, rather than on the end of the support plate 1.61, which makes the power platform more stable.

[0210] Furthermore, the positioning handle 1.5 is located above the placement space 1.41, making the center of the power platform more upward, which makes the existence of the support structure 1.6 more necessary. When the positioning handle 1.5 extends out of the water tank, the support plate 1.61 in the support structure 1.6 can be retracted and hidden at the lower end face of the lower shell 1.4 to prevent the support plate 1.61 from taking up extra space.

[0211] In a further preferred embodiment, the positioning handle 1.5 is engaged with the side wall of the water tank via the handle portion 1.53. The outer layer of the handle portion 1.53 is provided with an elastic surface layer. The elastic surface layer allows the positioning handle 1.5 to abut more tightly against the inner wall of the water tank and also reduces the processing accuracy requirements of the positioning handle 1.5. Even if the extended length of the positioning handle 1.5 makes the power platform slightly shorter than the width of the water tank, the presence of the elastic surface layer can provide an appropriate gap to make the engagement of the power platform more secure.

[0212] In a further preferred embodiment, the positioning handle 1.5 has a side arm 1.54 on each side, and a counterweight 1.541 is provided at the end of each side arm 1.54 away from the handle part 1.53. When the positioning handle 1.5 is in the locked state, the counterweight 1.541 is located inside the space covered by the upper shell 1.3. In this embodiment, the counterweight 1.541 is made of a metal block with a high density, such as a stainless steel block.

[0213] In this embodiment, the setting of counterweight 1.541 can optimize several problems existing in the power platform, as follows:

[0214] ① When the positioning handle 1.5 is in the hidden state, the power platform is applied to the table. The counterweight 1.541 is located inside the shell on the side away from the placement space 1.41. This side is exactly opposite to the protruding end of the upper shell 1.3, that is, the protruding part above the placement space 1.41. Originally, the protruding end of the upper shell 1.3 caused the power platform to have the potential to tip over. However, the presence and position of the counterweight 1.541 greatly balance the problem of the center of gravity tilt caused by the protruding end, thus greatly improving the risk of the above-mentioned potential danger.

[0215] ② When the positioning handle 1.5 is in the locked position, the power platform is applied to the water tank. The distance between the extended position of the positioning handle 1.5 is relatively long. In the structure with a long extension, the end where the handle part 1.53 is located tends to sink, causing the positioning handle 1.5 to easily tilt towards the end where the handle part 1.53 is located. This causes the connection structure between the positioning buckle 1.51 and the hidden positioning hole 1.521 to be subjected to greater stress. When the hidden positioning hole 1.521 does not have a high-strength limiting structure, the locking of the positioning handle 1.5 and the water tank can easily become unstable or even fail.

[0216] At this time, by setting a counterweight 1.541 and keeping it inside the housing, the side arm 1.54 uses the edge of the housing as a fulcrum. The counterweight 1.541 balances the weight distribution of the positioning handle 1.5 in the locked state, which reduces or even eliminates the tendency of the positioning handle 1.5 to tilt towards the end where the handle part 1.53 is located, thereby improving the risk of locking failure.

[0217] In a preferred embodiment, the inside of the snap-fit ​​boss 1.31 is provided with a motor slot, the opening of which faces downwards. The side wall of the motor slot engages and limits the upper part of the dual-output motor 1.1. At the same time, the inner end of the snap-fit ​​groove 1.32 is provided with a coupling limiting wall, which abuts against and locks the side of the third output part 1.22 on the phase-changing coupling 1.2. In this embodiment, the snap-fit ​​boss 1.31 and the snap-fit ​​groove 1.32 not only facilitate the integrated assembly of various cutting modules, but also limit the transmission structure through their own structure, preventing it from vibrating and jumping, and making the assembly of the transmission structure more stable.

[0218] In a further preferred embodiment, the first stop 1.63 or the second stop 1.64 is an elastic block to avoid rigid collisions when the support plate 1.61 extends or retracts.

[0219] In a further preferred embodiment, when the support plate 1.61 extends to its maximum extent, the center of gravity of the cutting and mixing machine power platform is projected onto the support plate 1.61 in the vertical direction to obtain a better support effect.

[0220] Please refer to Figures 6-9. This embodiment relates to a preferred extrusion module, wherein:

[0221] The dough-making cover 2.7 is provided with a water tank slot 2.71. The outer periphery of the water tank slot 2.71 has a shape that fits the lower outer contour of the water tank 2.8. The water tank slot 2.71 is provided with a dough-making inlet 2.72. The lower end of the water tank 2.8 has a water tank outlet that connects to the dough-making inlet 2.72 after being snapped on.

[0222] The dough mixing structure includes a mixing rod 2.6, which includes a rod body 2.61. The rod body 2.61 is vertically arranged in the working state, and a drive connection part 2.62 and a follower connection part 2.63 are respectively provided at both ends of the rod body 2.61. In the working state, a pre-mixing arm 2.64, an auxiliary mixing arm 2.65 and a main mixing arm 2.66 are arranged sequentially from top to bottom on the rod body 2.61.

[0223] The dough extrusion structure includes an extrusion screw 2.1 disposed in an extrusion channel below the dough container 2.5, the extrusion screw 2.1 having a drive end 2.11 and an extrusion end 2.12 disposed opposite to each other; it also includes an extrusion cover 2.2 fixed to one end of the extrusion channel, partially sleeved on the extrusion end 2.12, the extrusion cover 2.2 having a space inside for the extrusion screw 2.1 to rotate, and an extrusion outlet 2.21 with an opening facing downwards on its surface; it also includes an extrusion die 2.4 detachably covering the extrusion outlet 2.21, the extrusion die 2.4 having dough extrusion holes formed on it.

[0224] The technical solution in this embodiment provides a stable and detachable water tank assembly structure. The water tank 2.8 can be assembled simply by inserting it into the water tank slot 2.71. It also provides a dough mixing structure, where the drive connection 2.62 on the mixing rod 2.6 is connected to the power output, and the follower connection 2.63 is hinged to cooperate with the rotation of the mixing rod 2.6. During the addition of dough, the pre-mixing arm 2.64 first contacts the dough and forms a mixer, then the auxiliary mixing arm 2.65 further mixes the pre-mixed dough, and finally the main mixing arm 2.66 performs the mixing. A dough extrusion structure is also provided to extrude the mixed dough, and different shapes of pasta can be extruded by changing the extrusion die 2.4 with different extrusion hole shapes.

[0225] In one embodiment:

[0226] The water tank slot 2.71 is a strip-shaped groove, while the water tank 2.8 is a columnar body with a cross-section that matches the inner contour of the water tank slot 2.71.

[0227] The water tank slot 2.71 is provided with a dough-kneading water inlet 2.72, which is a protruding water inlet pipe and is integrally formed with the water tank slot 2.71. The lower end of the water tank 2.8 has a water tank outlet. The position of the water tank outlet is such that after the water tank 2.8 is engaged with the water tank slot 2.71, the water tank outlet is connected to the dough-kneading water inlet 2.72. Specifically, the connection method is: the protruding water inlet pipe corresponding to the dough-kneading water inlet 2.72 is inserted into the water tank outlet.

[0228] Furthermore: After the water tank 2.8 is snapped in, the water tank outlet is connected to the dough inlet 2.72 through the check valve 2.81. At this time, the check valve 2.81 is inserted by the protruding inlet pipe to open it to the flow state.

[0229] In the preferred technical solution, the dough inlet 2.72 is located at one end of the bottom of the water tank slot 2.71.

[0230] In the technical solution of this embodiment, the basic function is as follows: before the stop valve 2.81 is connected to the dough inlet 2.72, it is in a stop state, and the water in the water tank 2.8 will not flow out. After the stop valve 2.81 is connected to the dough inlet 2.72, it is in a flow state. The water droplets in the water tank 2.8 are added to the dough container 2.5 to form dough flakes with appropriate water content. When water needs to be added again, simply pull out the water tank 2.8, add an appropriate amount of water, and then insert it back into the water tank slot 2.71.

[0231] The advanced function of this embodiment is that the protruding water inlet pipe also serves as an auxiliary positioning tool, making the water tank 2.8 more securely installed. The water inlet 2.72 is located at one end of the bottom of the water tank slot 2.71. This arrangement can prevent the water tank 2.8 from being installed backwards. Furthermore, the water tank 2.8 is only located in the area above the water tank slot 2.71 and will not occupy additional space.

[0232] In a preferred embodiment, a strip-shaped first portable protrusion 2.73 is provided in the middle of the dough cover 2.7, a water tank slot 2.71 is provided on one side of the first portable protrusion 2.73, a water tank cover 2.9 is provided on the water tank 2.8, a strip-shaped second portable protrusion 2.91 is provided on the water tank cover 2.9, and a gradually expanding base structure is provided at the lower part of both the first portable protrusion 2.73 and the second portable protrusion 2.91;

[0233] In the technical solution of this embodiment, the first portable protrusion 2.73 makes it convenient for the user to hold the dough container 2.5 by hand, the second portable protrusion 2.91 makes it convenient for the user to hold the water tank 2.8 by hand, and the setting position of the water tank slot 2.71 is conducive to the utilization and arrangement of the upper space of the dough cover 2.7. The above-mentioned base structure can form a hand-held base.

[0234] In one embodiment:

[0235] In the dough mixing structure, the auxiliary mixing arm 2.65 has a dough extrusion area 2.67 formed at the end away from the rod 2.61, and the main mixing arm 2.66 has a dough return baffle 2.661 that protrudes toward the dough extrusion area 2.67 at the end away from the rod 2.61;

[0236] When the rod 2.61 rotates, the circular trajectory formed by the outer contour of the dough return stop 2.661 can be adjacent to the inner wall contour of the dough container 2.6.

[0237] In this embodiment, after the dough flakes are added to the mixing container 2.5, the pre-mixing arm 2.64 first contacts the dough flakes and forms a mixing action. Then, the auxiliary mixing arm 2.65 further mixes the pre-mixed dough flakes. Finally, the main mixing arm 2.66 mixes the dough flakes. The dough flake return baffle 2.661 on the main mixing arm 2.66 can scrape the dough flakes scattered on the inner wall of the mixing container 2.5 and guide them into the dough flake extrusion area 2.67. Then, the auxiliary mixing arm 2.65 performs a second mixing of the guided dough flakes in the dough flake extrusion area 2.67 to improve the elasticity and texture of the dough flakes, thereby obtaining a more delicious pasta.

[0238] In a preferred embodiment, the pre-stirring arm 2.64 extends from the rod 2.61 at a greater distance than the auxiliary stirring arm 2.65 extends from the rod 2.61, and the main stirring arm 2.66 extends from the rod 2.61 at a greater distance than the auxiliary stirring arm 2.65 extends from the rod 2.61. That is, the pre-stirring arm 2.64 has a longer length than the auxiliary stirring arm 2.65, and the main stirring arm 2.66 also has a longer length than the auxiliary stirring arm 2.65.

[0239] Generally speaking, the end of the stirring arm has a stronger stirring effect and a more thorough stirring action. Therefore, in the technical solution of this embodiment, the pre-stirring arm 2.64 stirs the flour flakes within a larger rotation range. The stirring area of ​​the auxiliary stirring arm 2.65 is different from that of the pre-stirring arm 2.64, so that the flour flakes in different areas are thoroughly stirred. Similarly, the main stirring arm 2.66 has a larger stirring range and needs to cooperate with the scraping action of the flour flake return baffle 2.661 and facilitate the formation of the flour flake extrusion area 2.67. The stirring range of the main stirring arm 2.66 should be as large as possible. In this embodiment, its length is greater than that of the pre-stirring arm 2.64.

[0240] In a preferred embodiment, the pre-stirring arm 2.64 and the auxiliary stirring arm 2.65 extend in opposite directions from the rod body 2.61. This arrangement reduces mutual interference between the two and ensures that they are distributed as evenly as possible within the dough mixing container 2.5, minimizing the probability of any dough clumps not being stirred.

[0241] In a preferred embodiment, in the working state, the upper surface of the auxiliary stirring arm 2.65 is provided with a first guide side 2.651, and the first guide side 2.651 has a downwardly extending inclined surface in the extension direction of the rod body 2.61;

[0242] The upper surface of the pre-stirring arm 2.64 is provided with a second guide side 2.641, and the second guide side 2.641 has a downwardly extending inclined surface in the extension direction of the rod body 2.61;

[0243] In the technical solution of this embodiment, the first guide side 2.651 and the second guide side 2.641 use centrifugal force to make the dough flakes move outward and downward, so that they can be scraped up by the dough flake return baffle 2.661 for secondary stirring.

[0244] In a further preferred embodiment, the auxiliary stirring arm 2.65 and the main stirring arm 2.66 are disposed on the same side of the rod body 2.61, so that the auxiliary stirring arm 2.65 acts on the dough flakes scraped up by the dough flake return baffle 2.661 in the first instant.

[0245] In this embodiment, the top-view projection relationship of the pre-stirring arm 2.64, the auxiliary stirring arm 2.65, and the main stirring arm 2.66 is as follows: the auxiliary stirring arm 2.65 and the main stirring arm 2.66 have projection areas that extend in the same direction and partially overlap; the pre-stirring arm 2.64 and the auxiliary stirring arm 2.65 have projection areas that extend in opposite directions; and the pre-stirring arm 2.64 and the main stirring arm 2.66 have projection areas that extend in opposite directions.

[0246] In a preferred embodiment, in the working state, the upper surface of the main stirring arm 2.66 is provided with a third guide side 2.662, which has a downwardly extending inclined surface along the direction pointing to the rod body 2.61. The dough floc return baffle 2.661 is provided with a fourth guide side 2.663 on the side near the rod body 2.61, which also has a downwardly extending inclined surface along the direction pointing to the rod body 2.61. In this embodiment, the third guide side 2.662 and the fourth guide side 2.663 are used to guide the dough flocs after secondary stirring to be further output downwards.

[0247] In a further preferred embodiment, the water inlet 2.72 is positioned such that the dripping point is located on the inner wall of the dough mixing container 2.5. This arrangement allows the dough flakes to form first on the inner wall of the dough mixing container 2.5 under the guidance of the first guide side 2.651 and the second guide side 2.641 of the stirring rod 2.6, combined with the centrifugal force of the flour. These flakes are then caught by the flake return baffle 2.661 and guided to the flake extrusion area 2.67, where the auxiliary stirring arm 2.65 performs secondary stirring. This creates a path of flake formation-extrusion-secondary stirring, which improves the stirring efficiency of the flakes and also produces a chewy and delicious pasta.

[0248] In one embodiment:

[0249] The extrusion structure for the dough includes a long strip-shaped extrusion channel, an extrusion screw 2.1, an extrusion cover 2.2, an extrusion fixing component 2.3, and an extrusion die head 2.4;

[0250] The extrusion screw 2.1 is located in the middle of the extrusion channel. One end of the extrusion screw 2.1 is the drive end 2.11, and the other end is the extrusion end 2.12. The drive end 2.11 is connected to a power output shaft to drive the extrusion screw 2.1 to rotate. The extrusion end 2.12 is provided with an extrusion outlet 2.21.

[0251] The extrusion cover 2.2 is a cylindrical component and is sleeved onto part of the extrusion screw 2.1 from the extrusion end 2.12. The interior of the extrusion cover 2.2, together with the extrusion channel, forms a space for the extrusion screw 2.1 to rotate. The extrusion outlet 2.21 is provided on the lower surface of the extrusion cover 2.2. A first limiting ring 2.22 is provided at the end of the extrusion cover 2.2 adjacent to the dough container 2.5. For example, the extrusion cover 2.2 includes a cylindrical first tubular component 2.23. The first limiting ring 2.22 is turned outward and provided at one end of the first tubular component 2.23. The other end of the first tubular component 2.23 is closed to prevent dough flakes from being extruded from that end. The extrusion outlet 2.21 is opened on the lower end of the first tubular component 2.23, corresponding to the extrusion end 2.12 of the extrusion screw 2.1. In this way, the dough flakes can be extruded by their own gravity.

[0252] The extrusion fixing component 2.3 is an annular component whose shape matches the extrusion cover 2.2. It is provided with an outer cover through hole 2.31, a second limiting ring 2.32 and an internal thread. The internal thread is screwed into the external thread on the dough container 2.5 to form a fixing structure.

[0253] The outer cover through hole 2.31 is fitted onto the extrusion outer cover 2.2. The internal thread fixing structure fixes the extrusion fixing member 2.3 to a protruding external thread on the dough mixing container 2.5. A partially overlapping snap-fit ​​portion is formed between the first limiting ring 2.22 and the second limiting ring 2.32. Another snap-fit ​​portion is formed on the dough mixing container 2.5 that contacts the first limiting ring 2.22. The two snap-fit ​​portions cause the first limiting ring 2.22 to snap between the extrusion fixing member 2.3 and the dough mixing container 2.5.

[0254] For example, the extrusion fastener 2.3 has a cylindrical second tubular member 2.33, a second limiting ring 2.32 is opened at one end of the second tubular member 2.33 and turned inward, and an internal thread fixing structure is provided on the inner wall of the other end of the second tubular member 2.33. The inner contour of the second limiting ring 2.32 surrounds and forms the above-mentioned outer cover through hole 2.31.

[0255] The extrusion die 2.4 is detachably covered at the extrusion outlet 2.21, and a surface extrusion section is formed on the extrusion die 2.4.

[0256] The technical solution described in this embodiment provides a feasible dough extrusion structure, and by changing the dough extrusion part with different shaped extrusion holes, the extrusion die 2.4 can extrude different shapes of pasta. For example, when the dough extrusion hole is a fine hole, fine noodles are extruded; when it is a coarse hole, coarse noodles are extruded; when it is a flat hole, wide noodles are extruded; when it is a longer slit, dough sheets are extruded, and after a little slicing, small pieces of dough are formed, etc.

[0257] In actual operation, the dough flakes first fall onto the extrusion screw 2.1 in the extrusion channel. The extrusion screw 2.1 is driven to rotate, pushing the dough flakes towards the extrusion outlet 2.21. Since one end of the first tubular member 2.23 is closed, the dough flakes will only be squeezed out from the extrusion outlet 2.21, forming different shapes of pasta with different shaped dough extrusion holes.

[0258] In a preferred embodiment, the extrusion die 2.4 is a curved sheet-like component. The extrusion die 2.4 covers the extrusion outlet 2.21 from the inner wall of the first tubular component 2.23. The curvature of the extrusion die 2.4 matches the shape of the inner wall contour of the first tubular component 2.23. That is, the extrusion die 2.4 fits and covers the extrusion outlet 2.21 from the inside out, making it less likely for the extrusion die 2.4 to fall out and the state during extrusion is relatively stable.

[0259] In a further preferred embodiment, the first limiting ring 2.22 includes a limiting portion protruding into the first tubular member 2.23, and the extrusion die head 2.4 has a defined limiting length, which is the same as the distance from the limiting portion to the closed end.

[0260] In this embodiment, the combined structure of the limiting part and the closed end forms the basis of the limiting extrusion die 2.4. Since the limiting length of the extrusion die 2.4 is the same as the distance from the limiting part to the closed end, the extrusion die 2.4 can be just snapped between the limiting part and the closed end. No additional positioning structure is needed to position the extrusion die 2.4, which simplifies the assembly structure of the extrusion die 2.4 and makes the assembly process of the extrusion die 2.4 faster and more convenient.
