Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a stirring assembly and stirring device. Background Technology

[0002] With the continuous improvement of living standards, various kitchen appliances and tools have emerged in an endless stream. Mixing devices can quickly mix minced meat and flour, greatly reducing the workload of users. The main component of a mixing device is the mixing assembly inside the container. The mixing assembly includes a rotating main shaft and a processing part extending from the side of the main shaft. Due to the different functions, the main shaft and the processing part are made of different materials, so they cannot be molded as a single piece. Instead, the main shaft and the processing part can only be fixed together by a fixing structure.

[0003] Generally, the spindle uses contour machining to create a fixing groove that matches the outer contour of the workpiece to hold it in place. However, because the positioning contours of the spindle and the workpiece are relatively long during contour positioning, they are prone to wear or localized deformation due to slight relative movements. Over time, the edges of the fixing groove can deform, causing the gap between the fixing groove and the workpiece to gradually increase, leading to loosening between the spindle and the workpiece and affecting the mixing effect. Utility Model Content

[0004] The purpose of this invention is to provide a stirring assembly and stirring device. The stirring assembly is not easily deformed or worn, which improves the stability and service life between the workpiece and the rotating shaft.

[0009] As an optional embodiment of the above-mentioned stirring assembly, the locating pin is interference-fitted with the machined part.

[0010] As an alternative to the above-mentioned stirring assembly, the processing component includes at least two processing parts, and the positions of at least two of the processing parts relative to the main shaft are not exactly the same along the axial direction of the main shaft.

[0011] As an optional embodiment of the above-mentioned stirring assembly, the fixing member includes a support surface that is perpendicular to the axial direction of the main shaft.

[0012] As an optional embodiment of the above-mentioned stirring assembly, the processing component includes a processing section, and along the rotation direction of the rotating shaft, the front end of the processing section is provided with a cutting edge; or

[0013] The processed part includes a processing section, which includes a first stirring section and a second stirring section that are connected to each other and arranged at an angle.

[0014] A stirring device includes the stirring assembly, a cover plate, a base, and a drive assembly. The cover plate is fastened to the base, the stirring assembly is disposed inside the base, the driven part passes through the cover plate, and the drive assembly is detachably connected to the driven part and can drive the stirring assembly to rotate.

[0015] As an optional embodiment of the above-mentioned stirring device, the bottom of the base is provided with a stabilizing shaft, the bottom surface of the fixing member is provided with a stabilizing hole, and the fixing member is sleeved on the stabilizing shaft through the stabilizing hole and can rotate relative to the stabilizing shaft.

The rotating shaft of the stirring assembly includes a detachably connected pressure cap and a fixing member, which can clamp and fix the workpiece, thereby securing the workpiece to the rotating shaft. The connecting post and locating pin of the fixing member both pass through the workpiece, thus providing at least two positioning references for the workpiece, ensuring the relative stability of the position between the workpiece and the rotating shaft.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] This embodiment provides a stirring device, such as... Figure 1 and Figure 2 As shown, the mixing device includes a cover plate 1, a base 2, and a mixing component 4. The base 2 is used to hold the ingredients to be mixed (such as minced meat or flour). The mixing component 4 is disposed inside the base 2. The cover plate 1 is fastened to the base 2. The mixing component 4 passes through the cover plate 1 so that the user can rotate the mixing component 4. The rotation of the mixing component 4 can mix the ingredients. The cover plate 1 can reduce the possibility of the ingredients splashing out of the base 2 during the mixing process and also helps to prevent the mixing component 4 from flying out and causing injury.

[0038] To optimize the user experience, the mixing device also includes a drive assembly 3, which is connected to the mixing assembly 4 to automatically drive the mixing assembly 4 to rotate, thereby improving mixing efficiency and saving manpower. For easy storage, the drive assembly 3 and the mixing assembly 4 are detachably connected, allowing the drive assembly 3 to be stored separately, and enabling the individual components to be stored in a small space, thus improving space utilization.

[0039] like Figure 3 and Figure 4 As shown, the stirring assembly 4 includes a main shaft 411, with a driven part 412 at one end and a processing part 42 at the other end. The driven part 412 passes through the cover plate 1 and is detachably connected to the drive assembly 3. When the drive assembly 3 is started, it drives the main shaft 411 to rotate via the driven part 412, which in turn drives the processing part 42 to rotate, thereby stirring the food in the base 2.

[0040] Generally speaking, the spindle 411 only serves to transmit power and has low requirements for hardness and wear resistance, while the workpiece 42 is in direct contact with the food and there is relative movement. The surface of the workpiece 42 is prone to wear, so it has higher requirements for hardness and wear resistance.

[0041] In some embodiments, the spindle 411 can be made of materials such as plastic or high-strength rubber, while the workpiece 42 can be made of metal. That is, the spindle 411 and the workpiece 42 can be fixed together by injection molding, which results in high processing efficiency, a smooth surface, and easy cleaning.

[0042] In some embodiments, the workpiece 42 can be clamped by the fixing member 414 and the spindle 411 and fixed by screws. This fixing method has a simple structure and facilitates the replacement of the workpiece 42. It is worth noting that in order to prevent the workpiece 42 from moving relative to the spindle 411, the fixing member 414 is provided with a positioning groove. The workpiece 42 is located in the positioning groove, and the positioning groove limits the workpiece 42 by its outer contour.

[0043] In this embodiment, the food processing device can be a cooking robot. This robot also has a cooking function, which can cook the processed ingredients and precisely control the heat, seasoning, and time to ensure consistent taste and doneness, as well as high serving efficiency, thus alleviating peak-hour pressure. It is worth noting that the cooking robot can also be equipped with a cutting and preparation function. This function can process specific ingredients, quickly slicing, shredding, and dicing them with uniform thickness and shape, avoiding human error and ensuring both aesthetic appeal and consistent cooking.

[0044] It is worth noting that in both of the above connection methods, the workpiece 42 is fixed by contouring the outer profile. However, because the positioning profiles of the spindle 411 and the workpiece 42 are relatively long during contour positioning, they are prone to wear or local deformation due to slight relative movements. As the service life increases, the positioning effect of the worn or locally deformed positioning profile decreases, causing loosening between the spindle 411 and the workpiece 42, thus affecting the mixing effect.

[0045] like Figure 4 As shown, the other end of the spindle 411 is provided with a pressure cap 413 and a fixing member 414. The fixing member 414 is detachably connected to the pressure cap 413 through a connecting post 417. The fixing member 414 is provided with a positioning pin 418. The machining part 42 is provided between the pressure cap 413 and the fixing member 414. Both the connecting post 417 and the positioning pin 418 pass through the machining part 42.

[0046] The rotating shaft 41 of the stirring assembly 4 includes a detachably connected pressure cap 413 and a fixing member 414. The pressure cap 413 and the fixing member 414 can clamp and fix the workpiece 42, thereby fixing the workpiece 42 to the rotating shaft 41. The connecting post 417 and the positioning pin 418 of the fixing member 414 are both inserted through the workpiece 42, thus providing at least two positioning references for the workpiece 42, thereby ensuring the relative stability of the position between the workpiece 42 and the rotating shaft 41. Because the connecting post 417, the positioning pin 418 and the hole have high machining accuracy, and the contour lines of the connecting post 417, the positioning pin 418 and the hole are short, they are not easily deformed and worn. Moreover, even if the positioning structure of the fixing member 414 is worn, the fixing member 414 can be replaced, which improves the stability and service life between the workpiece 42 and the rotating shaft 41.

[0047] Because the drive assembly 3 and the stirring assembly 4 are detachably connected, and the stirring assembly 4 only passes through the cover plate 1, there is no direct connection between the stirring assembly 4 and the cover plate 1. Therefore, the stability of the stirring assembly 4 within the base 2 is relatively poor. Figure 3 and Figure 5 As shown, to solve the above problems, a stabilizing shaft is provided at the bottom of the base 2, and a stabilizing hole 416 is provided on the bottom surface of the fixing member 414. The fixing member 414 is sleeved on the stabilizing shaft through the stabilizing hole 416 and can rotate relative to the stabilizing shaft. The stabilizing shaft can be radially limited at the bottom end of the rotating shaft 41 through the stabilizing hole 416. After the drive assembly 3 is connected to the top end of the stirring assembly 4, the rotating shaft 41 can be ensured to rotate stably.

[0048] In this embodiment, the processing part 42 includes a processing part 421 and a fixing part 422 connected to each other. The fixing part 422 is disposed between the pressure cap 413 and the fixing part 414. The processing part 421 extends radially along the main shaft 411 to stir the food in the base 2.

[0049] like Figure 3 As shown, in some embodiments, a cutting edge 4211 is provided at the front end of the processing part 421 along the rotation direction of the rotating shaft 41. This kind of stirring device is suitable for stirring minced meat. The cutting edge 4211 can cut the minced meat, thereby making the minced meat finer.

[0050] like Figure 5 As shown, in some embodiments, the processing component 42 includes a processing section 421, which includes a first stirring section 4212 and a second stirring section 4213 connected to each other and arranged at an angle. This type of stirring device is suitable for stirring flour for kneading. The structure of the first stirring section 4212 and the second stirring section 4213 can increase the stirring range of the processing component 42, thereby fully stirring the flour in the base 2 and improving the stirring effect.

[0051] In this embodiment, the processing component 42 includes at least two processing parts 421. Along the axial direction of the main shaft 411, the positions of the at least two processing parts 421 relative to the main shaft 411 are not exactly the same. That is, the height positions of the at least two processing parts 421 relative to the bottom surface of the base 2 are not exactly the same, so as to further expand the stirring range of the processing component 42 and improve the stirring effect.

[0052] Optionally, the fixing member 414 includes a supporting surface 415, which is perpendicular to the axial direction of the main shaft 411. After the stabilizing hole 416 of the stirring assembly 4 is fitted onto the stabilizing shaft and food is loaded into the base 2, the supporting surface 415 abuts against the bottom surface of the base 2. When the cover plate 1 is fastened, it can ensure that the axis of the main shaft 411 is perpendicular to the bottom surface of the base 2, that is, the main shaft 411 is vertically set, so that the driven part 412 at the top of the main shaft 411 can pass through the cover plate 1.

[0053] like Figure 4 and Figure 6 As shown, the drive assembly 3 includes a drive motor, a housing 31, and an output component 32. The drive motor is housed within the housing 31, and its output shaft is coaxially connected to the output component 32. The output component 32 has an output groove 321, and the inner wall of the output groove 321 is provided with output teeth 322. The driven part 412 includes a transmission tooth 4121 protruding from the side wall of the main shaft 411. The main shaft 411 is inserted into the output groove 321, and the output tooth 322 abuts against the side wall of the transmission tooth 4121. When the drive motor drives the output component 32 to rotate, the output tooth 322 can drive the main shaft 411 to rotate through the transmission tooth 4121, thereby providing rotational power for the workpiece 42.

[0054] Optionally, the output component 32 includes multiple spaced output teeth 322, with transmission teeth 4121 located between two adjacent output teeth 322. This structure allows the output component 32 to quickly drive the spindle 411 to rotate, whether rotating forward or backward. Furthermore, the starting speed is low, resulting in less impact force between the output teeth 322 and the transmission teeth 4121, thus preventing damage.

[0055] Similarly, the driven part 412 includes a plurality of spaced transmission teeth 4121, each transmission tooth 4121 being located between two adjacent output teeth 322. This structure ensures that when the output member 32 rotates, its driving force is evenly distributed among the multiple transmission teeth 4121, which not only improves the uniformity of the force on the driven part 412, but also reduces the interaction force between each output tooth 322 and the transmission tooth 4121, preventing damage.

[0056] It is worth noting that the multiple transmission teeth 4121 are equally spaced and the multiple output teeth 322 are equally spaced, so that the output component 32 and the rotating shaft 41 can be inserted at various relative angles.

[0057] like Figure 1 and Figure 6 As shown, to ensure stability when the drive assembly 3 is connected to the rotating shaft 41, the housing 31 of the drive assembly 3 is provided with at least two anti-rotation grooves 311, and the cover plate 1 is provided with at least two anti-rotation pins 12 corresponding to the at least two anti-rotation grooves 311, and the anti-rotation pins 12 are inserted into the corresponding anti-rotation grooves 311. When both anti-rotation pins 12 are inserted into the corresponding anti-rotation grooves 311, the drive assembly 3 and the cover plate 1 can be locked at a relative angle to ensure stability.

[0058] Optionally, at least two anti-rotation grooves 311 are equally spaced along the circumference of the rotation axis 41. This structure allows the drive assembly 3 to be adapted to the cover plate 1 at various relative angles, improving the flexibility of use.

[0059] In this embodiment, the housing 31 of the drive assembly 3 is provided with three anti-rotation grooves 311, and the cover plate 1 is provided with three anti-rotation pins 12. It can be understood that the drive assembly 3 is provided with three anti-rotation grooves 311, which enables the drive assembly 3 and the cover plate 1 to be adapted to three relative angles.

[0060] Understandably, when the stirring device is stirring the food, the output component 32 rotates at a high speed and vibrates significantly, resulting in poor relative stability between the drive component 3 and the cover plate 1. To improve the stability between the cover plate 1 and the drive component 3 when the user presses the drive component 3 onto the cover plate 1, the cover plate 1 is provided with a limiting groove 11. The driven part 412 passes through the bottom surface of the limiting groove 11. When the drive component 3 is connected to the driven part 412, part of the drive component 3 is located within the limiting groove 11.

[0061] The limiting groove 11 can abut against the outer periphery of the housing 31 of the drive assembly 3, thereby increasing the contact area between the drive assembly 3 and the cover plate 1. It can also limit the movement of the drive assembly 3 and the cover plate 1 in both the horizontal and vertical directions, ensuring relative stability between them. Furthermore, since part of the housing 31 of the drive assembly 3 enters the limiting groove 11, the cover plate 1 can block the gap between the housing 31 and the cover plate 1. Even if the drive assembly 3 tilts during startup, the user's hand cannot enter between the housing 31 and the cover plate 1, ensuring user safety.

[0062] Since the drive assembly 3 is prone to vibration during the drive process, in order to ensure the stability of the drive assembly 3 and reduce noise, the housing 31 is provided with several buffers 33. The buffers 33 are pressed against the housing 31 and the cover plate 1, which can achieve flexible contact and absorb vibration, reduce the collision between the housing 31 and the cover plate 1, and reduce noise.

[0063] In this embodiment, to ensure the reliability of the connection between the fixing member 414 and the pressure cap 413, the stirring assembly 4 also includes a fixing screw. The fixing member 414 is fixed to the pressure cap 413 by the fixing screw to ensure that the rotating shaft 41 can fix the workpiece 42. To simplify the structure, the stabilizing hole 416 is a countersunk hole, and the fixing screw is set in the stabilizing hole 416 and threadedly connected to the main shaft 411.

[0064] Understandably, since the fixing screw secures the gland 413 and the fastener 414 via the connecting post 417, the connecting post 417 may be slightly deformed due to the pressure exerted by the fixing screw. Figure 4 As shown, to prevent the connecting post 417 from deforming and affecting the positioning and limiting of the workpiece 42, in this embodiment, the fixing member 414 is provided with two positioning pins 418, and the workpiece 42 is correspondingly provided with two positioning holes 423. The positioning pins 418 are inserted into the corresponding positioning holes 423 for positioning. By positioning and limiting the workpiece 42 through the two positioning pins 418, the connecting post 417 and the workpiece 42 can be clearance-fitted, thereby ensuring that the deformation of the connecting post 417 will not affect the relative position between the workpiece 42 and the rotating shaft 41.

[0065] Optionally, the locating pin 418 is interference-fitted with the workpiece 42. This improves the tightness of the fit between the workpiece 42 and the rotating shaft 41, and ensures that the rotating shaft 41 and the workpiece 42 are still effectively positioned even when the locating pin 418 or the locating hole 423 is slightly worn.

[0066] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
