Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a stirring device and agitator. Background Technology

[0002] Household electric meat grinders are widely used due to their ease of operation. Current models typically have a fixed positioning shaft at the bottom of the grinding bowl, with the bottom of the blade shaft fitted onto this shaft and the top connected to the motor output shaft. A bowl lid is installed between the bowl and the motor, with a through hole in the center for the blade shaft to pass through. The motor drives the blade shaft to rotate and grind the material. However, due to the assembly gap between the blade shaft and the through hole in the bowl lid, food particles can splash out through this gap during grinding, easily causing contamination of the bowl lid and the motor. Utility Model Content

[0003] In view of this, the present invention provides a stirring device and a stirrer to solve the problem that, due to the assembly gap between the blade shaft and the through hole of the bowl lid, food particles splash out of the bowl lid during the chopping process, which easily causes contamination of the outside of the bowl lid and the motor.

[0004] In a first aspect, this utility model provides a stirring device, comprising:

[0005] The shell assembly has an internal stirring chamber and a through hole.

[0006] A stirring assembly is disposed inside the stirring chamber, and the driving end of the stirring assembly is used to connect to an external driving component through the through hole;

[0007] A protective cover is located inside the stirring chamber, is disposed on the stirring assembly, and its projection on the housing assembly covers the through hole.

[0008] Beneficial effects: This mixing device features a protective cover located inside the mixing chamber and mounted on the mixing assembly. The projection of the protective cover onto the housing assembly covers the through hole. When the mixing assembly mixes materials inside the mixing chamber, the protective cover effectively blocks splashed materials from directly reaching the through hole, preventing material from accumulating and clumping within it. It also prevents material from splashing out of the through hole to the outside of the housing assembly, keeping the exterior of the housing assembly clean. Furthermore, the drive components on the exterior of the housing assembly are less susceptible to material contamination. This not only facilitates daily cleaning and maintenance but also effectively reduces the failure rate of drive components caused by material contamination, ensuring the stable operation of the mixing device.

[0009] In one alternative embodiment, the stirring assembly includes a rotating shaft, and the protective cover includes:

[0010] Cover plate body;

[0011] A connecting hole is provided on the cover plate body, and the cover plate body is sleeved on the outer periphery of the rotating shaft through the connecting hole.

[0012] Beneficial effects: By providing connection holes on the cover plate body, and by fitting the cover plate body onto the outer periphery of the rotating shaft through the connection holes, an effective connection between the protective cover and the stirring assembly is achieved.

[0013] In one alternative embodiment, the connecting hole is interference-fitted with the rotating shaft.

[0014] Beneficial effects: Due to the interference fit between the connecting hole and the rotating shaft, the cover plate body can fit tightly with the rotating shaft. During the operation of the stirring assembly, it is ensured that the cover plate body can rotate synchronously with the rotating shaft and always maintain a stable relative position with the rotating shaft, effectively avoiding the problem of reduced protective effect due to loosening or displacement.

[0015] In one alternative embodiment, the protective cover further includes a protrusion that protrudes from the surface of the cover body, is disposed at the connection hole, and is fitted around the outer periphery of the rotating shaft.

[0016] Beneficial effects: By setting a protrusion at the connection hole and sleeved on the outer circumference of the rotating shaft, the contact area between the cover body and the rotating shaft is increased, enhancing the stability of the connection between the cover body and the rotating shaft. Furthermore, during the rotation of the rotating shaft, the interaction force between the rotating shaft and the cover body is distributed more evenly, effectively ensuring that the protective cover can always maintain a stable operating state.

[0017] In one alternative embodiment, the protective cover has a ring-shaped structure.

[0018] Beneficial effects: Due to the uniform force distribution of the annular structure, by setting the protective cover to an annular structure, when the protective cover is impacted by materials during the operation of the mixing component, the force can be effectively dispersed and evenly transmitted, thereby significantly reducing the risk of local deformation or damage to the protective cover, extending the service life of the protective cover itself, and ensuring the long-term stable protective performance of the protective cover.

[0019] In one alternative embodiment, a first gap exists between the outer peripheral edge of the protective cover and the inner wall of the stirring chamber.

[0020] Beneficial effects: By setting a first gap between the outer edge of the protective cover and the inner wall of the mixing chamber, the necessary space for the protective cover to rotate synchronously with the rotating shaft is provided. During the rotation of the protective cover, interference with the inner wall of the mixing chamber can be avoided, as well as direct contact or friction between the protective cover and the inner wall of the mixing chamber, which would generate additional resistance. This not only ensures that the protective cover and the mixing assembly can operate smoothly and stably, but also reduces energy loss and component wear caused by mechanical interference, and extends the service life of the protective cover and the housing assembly.

[0021] In one alternative embodiment, the stirring assembly includes a rotating shaft, the rotating shaft comprising:

[0022] The rotating shaft body has the protective cover fitted around its outer periphery.

[0023] A limiting protrusion is provided on the rotating shaft body; the protective cover is provided between the limiting protrusion and the through hole, and abuts against the limiting protrusion.

[0024] Beneficial effects: The setting of the limiting protrusion provides a clear and definite installation positioning benchmark for the protective cover, ensuring that the protective cover can be quickly and accurately installed in the designated position, avoiding repeated adjustments caused by ambiguous positioning, shortening installation time, and improving the assembly efficiency between the protective cover and the rotating shaft; and because the protective cover abuts against the limiting protrusion, the limiting protrusion forms a reliable axial limit on the protective cover, providing stable support and constraint for the protective cover. During the operation of the mixing assembly, the protective cover can effectively avoid the risk of accidental falling due to equipment vibration, rotational inertia, etc., ensuring that the protective cover is always stably fixed in the designated installation position, and ensuring the safe and reliable operation of the entire mixing device.

[0025] In one alternative implementation, the housing assembly includes:

[0026] case;

[0027] The cover is detachably fitted onto the housing and together with the housing to form the stirring chamber.

[0028] Beneficial effects: The cover can be detachably placed on the shell, forming a stirring chamber together with the shell. During maintenance, cleaning, and component replacement, the cover can be easily removed from the shell, facilitating a comprehensive and meticulous cleaning of the interior of the shell and the cover, thus improving the convenience and thoroughness of cleaning and maintenance.

[0029] In one alternative embodiment, the through hole is provided on the cover body, and a second gap exists between the cover body and the protective cover.

[0030] Beneficial effects: By setting the through hole on the cover, a reasonable and clear channel is provided for the connection between the rotating shaft and other components of the stirring assembly and the external drive unit. This facilitates the assembly and layout of the stirring assembly, cover, and external drive unit, making the entire stirring device more compact and rational in structure, and the installation process simpler and more efficient. Since the protective cover rotates with the rotating shaft during stirring, the second gap provides the necessary space for the protective cover to rotate synchronously with the shaft. During the rotation of the protective cover, interference with the cover body is avoided, as is direct contact or friction between the protective cover and the cover body, preventing additional resistance. This not only ensures the smooth and stable operation of the protective cover and the stirring assembly but also reduces energy loss and component wear caused by mechanical interference, extending the service life of the protective cover and the cover body.

[0031] Secondly, this utility model also provides a stirrer, comprising:

[0032] The aforementioned stirring device;

[0033] A driving component is connected to the driving end of the stirring assembly.

[0034] In one alternative implementation, the mixer is a meat grinder. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0057] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0058] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0059] According to an embodiment of the present invention, a stirring device is provided, including a housing assembly 1, a stirring assembly 2, and a protective cover 4; the housing assembly 1 has a stirring chamber 11 inside, and a through hole 12 on the housing assembly 1; the stirring assembly 2 is disposed in the stirring chamber 11, and the driving end of the stirring assembly 2 is used to pass through the through hole 12 and connect to an external driving component 3; the protective cover 4 is located in the stirring chamber 11, disposed on the stirring assembly 2, and its projection on the housing assembly 1 covers the through hole 12.

[0060] In the above embodiment, the stirring device is equipped with a protective cover 4 located inside the stirring chamber 11 and mounted on the stirring assembly 2. The projection of the protective cover 4 on the housing assembly 1 covers the through hole 12. When the stirring assembly 2 stirs the material in the stirring chamber 11, the splashed material is effectively blocked by the protective cover 4 because the projection of the protective cover 4 covers the through hole 12. This prevents the material from accumulating and clumping in the through hole 12 and avoids the material from splashing from the through hole 12 to the outside of the housing assembly 1, keeping the outside of the housing assembly 1 clean. The drive component 3 outside the housing assembly 1 is also less likely to be contaminated by the material. This not only facilitates daily cleaning and maintenance but also effectively reduces the failure rate of the drive component 3 caused by material contamination, ensuring the stable operation of the stirring device.

[0061] In one embodiment, the stirring assembly 2 includes a rotating shaft 21, and the protective cover 4 includes a cover plate body 41 and a connecting hole 42; the connecting hole 42 is disposed on the cover plate body 41, and the cover plate body 41 is sleeved on the outer periphery of the rotating shaft 21 through the connecting hole 42.

[0062] In the above embodiment, by providing a connection hole 42 on the cover plate body 41, and by sleeve the cover plate body 41 on the outer periphery of the rotating shaft 21 through the connection hole 42, an effective connection between the protective cover 4 and the stirring assembly 2 is achieved.

[0063] In one embodiment, the connecting hole 42 is interference-fitted with the rotating shaft 21.

[0064] In the above embodiment, since the connecting hole 42 is interference-fitted with the rotating shaft 21, the cover plate body 41 can fit tightly with the rotating shaft 21. During the operation of the stirring assembly 2, it is ensured that the cover plate body 41 can rotate synchronously with the rotating shaft 21 and always maintain a stable relative position with the rotating shaft 21, effectively avoiding the problem of reduced protection effect due to loosening or displacement.

[0065] In one embodiment, the protective cover 4 further includes a protrusion 43, which protrudes from the surface of the cover body 41, is disposed at the connection hole 42, and is sleeved on the outer periphery of the rotating shaft 21.

[0066] In the above embodiment, by providing a protrusion 43 at the connection hole 42 and sleeved on the outer periphery of the rotating shaft 21, the contact area between the cover body 41 and the rotating shaft 21 is increased, enhancing the stability of the connection between the cover body 41 and the rotating shaft 21. Furthermore, during the rotation of the rotating shaft 21, the interaction force between the rotating shaft 21 and the cover body 41 is distributed more evenly, effectively ensuring that the protective cover 4 can always maintain a stable operating state.

[0067] In some embodiments, the protrusion 43 can be a convex ring, which is sleeved on the outer periphery of the rotating shaft 21. The convex ring can form a tight circumferential fit with the rotating shaft 21, which improves the overall structural rigidity and coaxiality. During the rotation of the rotating shaft 21, the eccentric vibration of the protective cover 4 is effectively avoided, ensuring smooth operation. Furthermore, the continuous annular contact surface provides uniform support and force transmission path, avoiding local stress concentration, which not only enhances the load-bearing capacity but also extends the service life of the rotating shaft 21 and the protective cover 4 as a whole.

[0068] In other embodiments, the protrusion 43 may include multiple protrusions, and multiple protrusions are evenly arranged around the outer periphery of the rotating shaft 21; the discrete design of the multiple protrusions allows the rotating shaft 21 and the protective cover 4 to generate small relative displacements when thermally expanded or deformed by force, effectively avoiding the over-constraint problem that may occur with integral protrusions, and improving the reliability of the stirring device; and the evenly distributed protrusions ensure the symmetry and stability of load transmission, preventing local overload and uneven wear.

[0069] In one embodiment, the protective cover 4 has a circular structure.

[0070] In the above embodiments, since the annular structure is subjected to uniform force, by setting the protective cover 4 as an annular structure, when the protective cover 4 is impacted by materials during the operation of the stirring assembly 2, the force can be effectively dispersed and uniformly transmitted, thereby significantly reducing the risk of local deformation or damage to the protective cover 4, extending the service life of the protective cover 4, and ensuring the long-term stable protective performance of the protective cover 4.

[0071] In a specific implementation, the protective cover 4 is coaxially arranged with the rotating shaft 21. During the operation of the stirring device, ensuring the dynamic balance between the protective cover 4 and the rotating shaft 21 can effectively avoid the tilting problem of the protective cover 4 caused by the eccentricity between the rotating shaft 21 and the protective cover 4, reduce the additional stress and instability caused by the tilt, and improve the stability and reliability of the protective cover 4 during the operation of the stirring device.

[0072] In one embodiment, the outer diameter of the protective cover 4 is larger than the diameter of the through hole 12. This ensures that the protective cover 4 can completely cover the area where the through hole 12 is located, effectively preventing splashed material from directly entering the through hole 12; and the larger outer diameter gives the protective cover 4 a larger coverage area, allowing it to effectively shield the through hole 12 without precise positioning during installation, thereby improving the ease of installation of the protective cover 4.

[0073] In some embodiments, the outer contour of the protective cover 4 can be set as a polygon, such as a triangle, quadrilateral, or pentagon. Compared to complex curves or circular contours, polygons composed of straight edges are simpler to design in molds. Whether it is an injection mold or a stamping mold, the design difficulty is greatly reduced, and it is also easier to operate during mold manufacturing, which can effectively shorten the mold manufacturing cycle. Moreover, the processing technology such as cutting, milling, and bending of straight edges is relatively mature and simple. Compared with the precise processing of complex curves, it is not only more convenient to operate, but also faster to process, and can effectively reduce processing costs. It helps to increase production speed in mass production and ensure product consistency, reducing production errors and defect rates caused by complex shapes. In addition, during sheet metal blanking or stamping, polygons are easier to arrange rationally than circles or other complex curved shapes, which can make fuller use of raw materials, reduce the generation of scrap, and thus reduce material costs.

[0074] In some embodiments, the outer contour of the protective cover 4 can be set as a polygon, and the distance between the center of the protective cover 4 and the edge of the outer contour of the protective cover 4 is greater than the diameter of the through hole 12. This ensures that the protective cover 4 can completely cover the area of ​​the through hole 12 no matter how it is rotated, effectively preventing splashed materials from entering the through hole 12; and the fact that the distance between the center of the protective cover 4 and the edge of the outer contour of the protective cover 4 is greater than the diameter of the through hole 12 gives the protective cover 4 a large coverage area, ensuring that the protective cover 4 has sufficient dimensional margin, so that the through hole 12 can be effectively shielded without precise positioning during installation, thereby significantly improving the convenience of installation.

[0075] In one embodiment, a first gap 5 exists between the outer peripheral edge of the protective cover 4 and the inner wall of the stirring chamber 11.

[0076] In the above embodiment, by setting a first gap 5 between the outer peripheral edge of the protective cover 4 and the inner wall of the stirring chamber 11, the necessary space for the protective cover 4 to rotate synchronously with the rotating shaft 21 is provided. During the rotation of the protective cover 4, interference with the inner wall of the stirring chamber 11 can be avoided, and direct contact or friction between the protective cover 4 and the inner wall of the stirring chamber 11 can be avoided to generate additional resistance. This not only ensures that the protective cover 4 and the stirring assembly 2 can operate smoothly and stably, but also reduces energy loss and component wear caused by mechanical interference, and extends the service life of the protective cover 4 and the housing assembly 1.

[0077] In one embodiment, the stirring assembly 2 includes a rotating shaft 21, which includes a shaft body 211 and a limiting protrusion 212; the protective cover 4 is sleeved on the outer periphery of the shaft body 211; the limiting protrusion 212 protrudes from the shaft body 211; the protective cover 4 is disposed between the limiting protrusion 212 and the through hole 12, and abuts against the limiting protrusion 212.

[0078] In the above embodiment, the setting of the limiting protrusion 212 provides a clear and definite installation positioning reference for the protective cover 4, ensuring that the protective cover 4 can be quickly and accurately installed in the designated position, avoiding repeated adjustments caused by ambiguous positioning, shortening the installation time, and improving the assembly efficiency between the protective cover 4 and the rotating shaft 21; and since the protective cover 4 abuts against the limiting protrusion 212, the limiting protrusion 212 forms a reliable axial limit on the protective cover 4, providing stable support and constraint for the protective cover 4. During the operation of the stirring assembly 2, the protective cover 4 can effectively avoid the risk of accidental falling due to equipment vibration, rotational inertia, etc., ensuring that the protective cover 4 is always stably fixed in the designated installation position, and ensuring the safe and reliable operation of the entire stirring device.

[0079] In some embodiments, the limiting protrusion 212 is a limiting flange, which protrudes from the outer periphery of the rotating shaft body 211.

[0080] In some other embodiments, the limiting protrusion 212 includes at least two protrusions, and the at least two protrusions are evenly distributed around the outer periphery of the rotating shaft body 211.

[0081] In some embodiments, the protrusion 43 is disposed between the cover plate body 41 and the through hole 12, and the limiting protrusion 212 abuts against the cover plate body 41. The protrusion 43 is located inside the through hole 12, and the diameter of the through hole 12 is larger than the outer diameter of the protrusion 43. That is, along the radial direction of the rotation axis 21, a third gap is provided between the inner wall of the through hole 12 and the protrusion 43. By providing a third gap between the inner wall of the through hole 12 and the protrusion 43, the necessary space for the protective cover 4 to rotate synchronously with the rotation axis 21 is provided. During the rotation of the protective cover 4, interference between the protrusion 43 and the inner wall of the through hole 12 can be avoided, as well as direct contact or friction between the protrusion 43 and the inner wall of the through hole 12 can be avoided, thus preventing additional resistance. This not only ensures that the protective cover 4 and the stirring assembly 2 can operate smoothly and stably, but also reduces energy loss and component wear caused by mechanical interference between the protrusion 43 and the inner wall of the through hole 12.

[0082] In other embodiments, the protrusion 43 is disposed between the cover plate body 41 and the through hole 12, and the limiting protrusion 212 abuts against the cover plate body 41. Furthermore, a fourth gap is provided between the protrusion 43 and the cover body 14 along the axial direction of the rotation shaft 21. By providing the fourth gap between the protrusion 43 and the cover body 14, necessary space for the protective cover 4 to rotate synchronously with the rotation shaft 21 is provided. During the rotation of the protective cover 4, interference between the protrusion 43 and the cover body 14 can be avoided, as well as direct contact or friction between the protrusion 43 and the cover body 14 that would generate additional resistance. This not only ensures that the protective cover 4 and the stirring assembly 2 can operate smoothly and stably, but also reduces energy loss and component wear caused by mechanical interference between the protrusion 43 and the cover body 14.

[0083] In some other embodiments, the protrusion 43 is disposed between the cover plate body 41 and the limiting protrusion 212, and the protrusion 43 abuts against the limiting protrusion 212.

[0084] In one embodiment, the housing assembly 1 includes a housing 13 and a cover 14; the cover 14 is detachably fitted onto the housing 13 and surrounds the housing 13 to form the stirring chamber 11.

[0085] In the above embodiment, the cover 14 is detachably covered on the housing 13, and together with the housing 13, they form the stirring chamber 11. When performing maintenance, cleaning, or component replacement, the cover 14 can be easily removed from the housing 13, which facilitates a comprehensive and meticulous cleaning operation of the inside of the housing 13 and the cover 14, thus improving the convenience and thoroughness of cleaning and maintenance work.

[0086] In a specific embodiment, a fixed shaft is fixedly installed on the bottom wall of the housing 13, and the fixed shaft includes a fixed end and a connecting end. The fixed end is fixedly connected to the bottom wall of the housing 13, and the connecting end protrudes from the bottom wall of the housing 13. The end of the rotating shaft 21 opposite to the driving end is provided with a first groove, and the connecting section is rotatably disposed in the first groove.

[0087] Specifically, the connecting section of the fixed shaft is a cylindrical structure, and the first groove is a circular groove that matches the shape of the connecting section of the fixed shaft, ensuring that the connecting section is rotatably disposed in the first groove.

[0088] In a specific embodiment, the drive shaft of the drive component 3 extends into the through hole 12, and the drive shaft is provided with a second groove. The drive end of the rotating shaft 21 is a prism structure, and the shape of the second groove matches the prism structure. The drive end is engaged in the second groove. When assembling, the drive end of the rotating shaft 21 is inserted into the second groove of the drive shaft, forming a stable engagement with the second groove. This not only effectively prevents relative sliding in the radial direction between the rotating shaft 21 and the drive shaft during transmission, but also ensures that the power generated by the drive component 3 can be efficiently and stably transmitted to the rotating shaft 21.

[0089] Preferably, the driving end of the driving component 3 protrudes from the rotating shaft body 211, and the outer diameter of the rotating shaft body 211 is larger than the outer diameter of the driving end. When assembled, the driving end of the rotating shaft 21 is inserted into the second groove of the driving shaft, and the driving shaft abuts against the rotating shaft body 211. The connecting section of the fixed shaft abuts against the groove wall of the first groove near the driving end, thereby limiting the axial movement of the rotating shaft 21. During the operation of the stirring device, the axial displacement of the rotating shaft 21 is prevented, ensuring the reliability and stability of the stirring device.

[0090] Preferably, a protective rubber pad is provided at the bottom of the housing 13. The protective rubber pad is assembled on the outer periphery of the bottom of the housing 13 in a covering structure. The protective rubber pad can absorb vibration kinetic energy, effectively avoiding wear and collision between the housing 13 and the contact surface during the operation of the stirring device, avoiding damage to the contact surface and housing 13 caused by rigid contact, and reducing vibration transmission efficiency, thus reducing operating noise. Furthermore, the protective rubber pad can also increase the friction between the housing 13 of the stirring device and the contact surface, ensuring the stability of the device when placed on the contact surface during operation.

[0091] In some embodiments, the material of the housing 13 is not limited; the housing 13 may be made of glass or stainless steel.

[0092] Preferably, the shell 13 can be a glass bowl.

[0093] In some embodiments, the material of the cover 14 is not limited; the cover 14 may be made of glass or stainless steel.

[0094] Preferably, the cover 14 can be a glass cover.

[0095] In some embodiments, the housing 13 and the cover 14 can be snapped together by a snap fastener, thereby achieving a detachable connection between the housing 13 and the cover 14.

[0096] Preferably, a sealing strip is provided on the side wall of the cover 14 near the housing 13. When the housing 13 and the cover 14 are closed, the sealing strip abuts against the inner wall of the housing 13. When the stirring device stirs the material, it can effectively block the material and prevent it from splashing out from the connection between the housing 13 and the cover 14 due to the centrifugal force generated by stirring, thereby ensuring the smooth progress of the stirring process and the cleanliness of the working environment.

[0097] In one embodiment, the through hole 12 is provided on the cover 14, and a second gap 6 exists between the cover 14 and the protective cover 4.

[0098] In the above embodiment, by setting the through hole 12 on the cover 14, a reasonable and clear channel is provided for the connection between the rotating shaft 21 and other components of the stirring assembly 2 and the external drive component 3. This facilitates the assembly and layout of the stirring assembly 2, the cover 14, and the external drive component 3, making the structure of the entire stirring device more compact and reasonable, and the installation process simpler and more efficient. Since the protective cover 4 rotates with the rotating shaft 21 during the stirring process, the setting of the second gap 6 provides the necessary space for the protective cover 4 to rotate synchronously with the rotating shaft 21. During the rotation of the protective cover 4, interference with the cover 14 can be avoided, and direct contact or friction between the protective cover 4 and the cover 14 can be avoided to prevent additional resistance. This not only ensures that the protective cover 4 and the stirring assembly 2 can operate smoothly and stably, but also reduces energy loss and component wear caused by mechanical interference, and extends the service life of the protective cover 4 and the cover 14.

[0099] In some embodiments, the cover 14 is provided with a mounting groove, and the drive component 3 is disposed in the mounting groove. This enhances the stability of the installation between the drive component 3 and the cover 14. During the operation of the stirring device, the drive component 3 is constrained by the mounting groove, effectively preventing it from falling off the cover 14 due to external forces such as vibration and impact, ensuring the continuous and stable operation of the stirring device. Furthermore, the mounting groove also provides some protection for the drive component 3, reducing damage caused by accidental collisions and thus extending its service life.

[0100] Specifically, the through hole 12 is located at the bottom of the mounting groove.

[0101] According to an embodiment of the present invention, another aspect provides a stirrer, including the above-described stirring device and a driving member 3; the driving member 3 is connected to the driving end of the stirring assembly 2.

[0102] In one embodiment, the mixer is a meat grinder.
