Description

Technical Field

[0001] This invention belongs to the field of transmission device technology, and specifically relates to a cooking mixer. Background Technology

[0002] With the ever-increasing pace of life, cooking blenders have emerged to alleviate the stress of cooking and save time and energy. A cooking blender is a modern kitchen appliance that integrates cooking and blending functions, offering multiple uses. Generally, a cooking blender consists of a cooking vessel, a mixer, an electric motor, and a control panel for controlling the mixer. The cooking vessel holds the ingredients; the electric motor drives the mixer to blend the ingredients, ensuring they are evenly distributed within the vessel; and the control panel controls the mixing mode. Therefore, when using a cooking blender to prepare dishes, users simply place the prepared ingredients in the cooking vessel, select the corresponding function on the control panel, and the mixer will automatically blend, easily preparing the desired dish.

[0003] The uniformity of mixing in a cooking blender directly affects the quality of cooked dishes. Therefore, current research and development of cooking blenders focuses primarily on the design of the blender itself. Specifically, patent CN210540735 U discloses a stir-fry machine that includes a body with an inner pot for holding cooking ingredients. A lid is hinged to one side of the body, and a stirring spatula is positioned in the center of the lid. After the lid is closed, the stirring spatula extends into the inner pot and stirs the ingredients through its rotation. To maximize the uniformity of stirring and cover the entire inner pot, this patent also features a special design for the stirring spatula: two cantilever arms, one long and one short, to stir the inner wall of the inner pot and the ingredients in the center, respectively. However, during lid opening, the end of the longer cantilever arm can easily get stuck on the inner wall of the inner pot, affecting the opening and closing of the lid. Therefore, this patent also incorporates a folding design for the stirring spatula, but its component structure is relatively complex and prone to accumulating dirt and grime.

[0004] Based on this, patent CN216393787U discloses an eccentric stirring stir-fry machine, which includes a separate pot body and a pot lid. The pot lid is equipped with a stirring spatula and a stirring motor. A transmission assembly connects the stirring spatula and the stirring motor. The transmission assembly includes a gearbox, a chassis, a stirring shaft, and a transmission gear. The top of the gearbox is fixedly connected to the pot lid. The gearbox is a cylindrical body with an open bottom. The chassis is located below the gearbox. The output shaft of the stirring motor passes through the gearbox and connects to the chassis. A gear ring is provided on the inner circumferential wall of the gearbox. The stirring shaft passes through a non-central part of the chassis. The transmission gear is fixedly connected to one end of the stirring shaft and meshes with the gear ring. The other end of the stirring shaft is connected to the stirring spatula. This utility model, through the arrangement of the transmission assembly, provides an eccentric stirring stir-fry machine that enables more even heating of the food, resulting in a better flavor.

[0005] However, the stirring surfaces of the aforementioned two types of stir-fry machines are relatively concentrated, only capable of continuously stirring ingredients within a certain area inside the pot. Therefore, they are more suitable for single-tasting applications such as stir-frying vegetables and fried rice, which, to some extent, limits their application scenarios. For applications such as whipping cream and egg whites, which require continuously stirring ingredients on the inner wall of the pot and thoroughly mixing the ingredients inside, these stir-fry machines cannot achieve ideal stirring results. Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional cooking mixer with high mixing flexibility, good effect, and wide range of applications, which is achieved through the following technical solution:

[0007] A cooking mixer includes a cooking dish, a lid for fastening onto the cooking dish, and a stirring component disposed on the lower surface of the lid for stirring ingredients within the cooking dish. The stirring component includes a stirring spatula and an adjusting assembly for adjusting the horizontal position of the stirring spatula. The adjusting assembly includes a fixing member for securing the stirring component, a telescopic member slidably connected to the fixing member, and a locking member for adjusting the relative position between the fixing member and the telescopic member. A mounting plate is provided at the end of the telescopic member away from the fixing member. The stirring component further includes a planetary gear disposed on the upper surface of the mounting plate, and a mounting platform penetrating the mounting plate and used for mounting the stirring spatula is provided on the lower surface of the planetary gear. The lid includes a gear assembly, which includes a large gear meshing internally with the planetary gear and a small gear meshing externally with the planetary gear. The lid also includes a drive shaft penetrating the center of the small gear and connected to the fixing member for driving the stirring component to rotate.

[0008] Compared to the relatively fixed design of existing stirring spatulas, this application first sets an adjustment component on the stirring spatula, and uses the cooperation of telescopic, fixed and locking components to give the stirring spatula the function of telescopic extension along the direction of the adjustment component, which increases the stirring surface of the stirring spatula blades. Therefore, during the stirring process, by manually adjusting the locking component, the stirring spatula can better and more fully take into account the ingredients inside the cooking vessel.

[0009] Secondly, considering that most applications of cooking blenders involve operation at high temperatures, to avoid the safety hazards of directly installing a rotary motor inside the mixing paddle, this application also achieves synchronous rotational drive of the drive shaft on the fixed component and the mixing paddle by incorporating a planetary gear detachably connected to the mixing paddle and a geared disc meshing with the planetary gear. Specifically, when the drive shaft is turned on, the fixed component rotates around the drive shaft as its central axis under the drive shaft's influence. At this time, based on the connection between the mounting plate and the fixed component, the mixing paddle mounted on the mounting plate will rotate along with the fixed component. Correspondingly, the planetary gear detachably connected to the mixing paddle rotates around the drive shaft under the drive of the mixing paddle, and based on its meshing relationship with the large or small geared disc, the planetary gear will further drive the mixing paddle to rotate in the opposite direction.

[0010] Based on this, as mentioned above, the planetary gears and the stirring shovel of this application are detachably connected. Therefore, without changing the gear disk assembly, the rotation speed of the stirring shovel can be adjusted by installing planetary gears of different diameters. This means that regardless of whether the planetary gears mesh with the large or small gear disk, different stirring intensity requirements can be met by replacing planetary gear parts of different diameters and models, making the stirring shovel extremely flexible.

[0011] Furthermore, this application also incorporates two different diameter large and small toothed discs, which, when combined with the telescopic component, allow for adjustment of the planetary gear's meshing position, thereby meeting various mixing needs. Specifically, when the planetary gear meshes externally with the small toothed disc, it is suitable for concentrated and dispersed applications such as stir-frying and fried rice; when the planetary gear meshes internally with the large toothed disc, it is suitable for applications such as whipping butter and egg whites. Regardless of the application, adjusting the telescopic component allows the planetary gear to switch positions between the small and large toothed discs. Therefore, the mixing spatula can better and more fully cover the ingredients inside the cooking dish, resulting in significantly better overall mixing performance compared to existing technologies.

[0012] In summary, this application, through the coordination of the structure, position, and installation relationship of the mixing spatula, adjusting components, gear disk assembly, and planetary gears, overcomes the limitations of the application scenarios of mixers mentioned in the background technology, increases the diversity of mixing power parameters, can meet various mixing and cooking needs of users, fundamentally realizes multi-purpose use of one machine, reduces the economic and space burden of purchasing multiple models of machines for users, and has extremely high practicality.

[0013] Preferably, the fixing member includes a swing arm groove with an opening on one side, one side of which is used for sliding connection with the telescopic member; the fixing member also includes a swing arm cover that covers the swing arm groove and is used to prevent the telescopic member from falling off; the swing arm groove includes an inner groove surface corresponding to the swing arm cover, and a boss is provided on the inner groove surface. A magnet is embedded in the side of the boss near the swing arm cover, and a transmission end for mounting a drive shaft is provided at the end of the boss away from the magnet.

[0014] As described above, the stirring speed of the mixing spatula in this application can be adjusted by replacing planetary gears of different diameters. However, when replacing the planetary gears, the user needs to disassemble the fixing component from the drive shaft. Therefore, if the installation between the fixing component and the drive shaft is complex, it will increase the difficulty of adjusting the stirring. To address this, this technical solution utilizes the inner surface of the tank, providing a boss on it, with magnets and transmission ends respectively at both ends of the boss. This greatly simplifies the disassembly and assembly steps between the fixing component and the drive shaft. While ensuring the adjustment component can adjust the horizontal position of the mixing spatula, it further enhances the convenience of flexible adjustment of the stirring parameters. Specifically, during installation, the drive shaft only needs to be brought close to the transmission end of the boss, and the magnet installed in the boss can form a tight connection with the drive shaft through magnetic attraction. At this time, the magnet can lift the stirring component by means of the magnetic attraction between itself and the drive shaft, completing the installation of the stirring component.

[0015] Furthermore, considering the application scenarios of the stirring component—which primarily comes into contact with food ingredients such as vegetables—to avoid hygiene issues caused by food residue remaining on the fixing, telescopic, and locking components after stirring, the fixing component in this technical solution is designed with a box-like structure. Specifically, by providing a swing arm groove and a swing arm cover that fits over it, food ingredients can be prevented from entering the interior of the fixing component, thus effectively avoiding the problem of food residue sticking together. In addition, the closing design of the swing arm groove and swing arm cover increases the ease of disassembly of the adjustment component, facilitates cleaning of stains, and has excellent practicality.

[0016] As a further preferred embodiment, the telescopic component further includes two parallel telescopic arms that are slidably connected to the inner wall of the swing arm groove and are used to drive the mounting plate to move; the inner groove surface is also provided with a limiting protrusion that is slidably connected to the telescopic arms and is used to limit the position of the telescopic arms.

[0017] This technical solution considers the design of the inner wall of the swing arm groove. By controlling the dimensions of the telescopic arm and the inner wall of the swing arm groove, the sliding position relationship between the two can be directly limited without setting up complicated components. The structural design is relatively simple and easy to operate. Furthermore, to avoid deviations during the manufacturing process of the swing arm groove and the telescopic arm, and to increase the stability of the telescopic arm sliding within the swing arm groove, this technical solution also provides a limiting protrusion on the inner surface of the groove. Therefore, during use, the cooking mixer with this technical solution allows adjustment of the horizontal position of the stirring spatula mounted on the mounting plate by sliding the telescopic arm and adjusting its length within the swing arm groove. This, in turn, allows the planetary gear to engage with the large or small gear disc, ultimately achieving eccentric stirring motion of the stirring spatula at different positions.

[0018] As a further preferred embodiment, the ends of the two telescopic arms away from the mounting plate are connected to each other to form an anti-disengagement arm to prevent the telescopic component from disengaging from the swing arm groove; the side of the two telescopic arms near the mounting plate is provided with a barrier plate to prevent the mounting plate from sliding into the swing arm groove.

[0019] In this technical solution, by setting anti-detachment arms at the ends of the two telescopic arms away from the mounting plate and setting baffle plates at the ends of the two telescopic arms close to the mounting plate, the sliding range of the telescopic arms within the swing arm groove can be effectively limited, avoiding the technical problem of difficult planetary gear meshing installation caused by telescopic arms that are too long or too short and are built into the swing arm groove. Furthermore, the baffle plate design also prevents collisions between the mixing shovel and the fixing components during the sliding of the telescopic arms, thus making the mixing component design more reasonable and reliable.

[0020] As a further preferred embodiment, the locking member includes a locking protrusion plate disposed on the inner groove surface, and a lead screw with one end disposed on the locking protrusion plate, the other end of the lead screw passing through the anti-disengagement arm and the swing arm groove in sequence along the extension and retraction direction of the telescopic member; a screw plate is provided at one end of the locking member passing through the swing arm groove; the locking member also includes a nut sleeved on the outer surface of the lead screw for driving the anti-disengagement arm to move along the lead screw.

[0021] This technical solution utilizes the positional relationship and structural design between the lead screw, locking cam, nut, tightening plate, and anti-disengagement arm to adjust the meshing position of the planetary gears, ultimately achieving multi-mode stirring of ingredients in the cooking dish. Specifically, the user manually turns the tightening plate to rotate the lead screw, which in turn moves the anti-disengagement arm along the lead screw via the nut that engages with it, adjusting the length of the telescopic arm built into the swing arm groove. Furthermore, compared to electric hydraulic drives, the manual tightening plate design in this technical solution better meets the needs of various stirring applications.

[0022] Preferably, the stirring shovel includes a stirring rod with blades and a sleeve that is axially slidably connected to the end of the stirring rod away from the blades. The stirring shovel also includes a fixing module for fixing the relative position of the stirring rod and the sleeve.

[0023] To further increase the mixing range of the stirring spatula, this technical solution establishes a relatively stable sliding connection between the stirring rod and the sleeve by setting up a stirring rod, a sleeve, and a fixing module, giving the stirring rod the function of extending and retracting along the axial direction of the sleeve. Therefore, based on the horizontal adjustment of the stirring spatula position by the adjusting component, the length of the stirring spatula can be further adjusted. It can be seen that this design can be used in conjunction with the adjusting component to further increase the mixing surface of the blades. Thus, the stirring spatula can better and more fully take into account the ingredients inside the entire cooking vessel, resulting in higher overall mixing flexibility and better mixing effect.

[0024] As a further preferred embodiment, the fixing module includes a mounting slot corresponding to and passing through the surfaces of the stirring rod and the sleeve, and a connector that mates with the mounting slot; the connector includes a first connector that passes through the mounting slot, and a second connector that mates with the first connector.

[0025] Since the stirring spatula needs to rotate continuously during use, the stability of the fixing module directly affects the stirring effect of the telescopic stirring spatula and even cooking safety. Therefore, in this technical solution, by setting an installation slot and corresponding connecting parts, the first and second connecting parts can fix the stirring rod and the sleeve to the corresponding installation slot. Specifically, the aforementioned installation slot can be multiple isolated slots or a single slot centrally located; the first and second connecting parts can be bolts and nuts, or pins and pins, etc.

[0026] As a further preferred embodiment, the stirring rod and the sleeve are respectively provided with positioning grooves, and the mounting slot is provided on the positioning grooves.

[0027] During the adjustment of the mixing spatula length, the user needs to first rotate and adjust the mixing rod and the sleeve to align their mounting slots before installing the connectors. To save on these adjustment steps and increase the convenience of adjusting the impeller mixing interface, this technical solution provides positioning grooves on the surfaces of the mixing rod and the sleeve. Furthermore, by placing the mounting slots on these positioning grooves, the visibility of the mounting slots is increased, further simplifying the installation process.

[0028] Preferably, the cover further includes a pot lid assembly and an electrical control box assembly that are sequentially connected to the upper surface of the gear disk assembly; a groove is provided at the center of the small gear disk protruding from the upper surface of the small gear disk, with the opening of the groove facing downwards; a connecting groove is provided on the lower surface of the electrical control box assembly for mounting the groove; the groove penetrates the pot lid assembly and is connected to the inner wall of the connecting groove; a pair of retaining plates abut against the inner walls of the groove, and an elastic mounting member is provided between the retaining plates to allow the retaining plates to abut against the inner wall of the groove; a first protrusion is provided at the lower end of the retaining plate to connect with the lower surface of the gear disk assembly, and a second protrusion is provided at the upper end of the retaining plate to penetrate the inner wall of the groove; a groove is provided on the side wall of the connecting groove to engage with the second protrusion.

[0029] The rotation of the stirring shovel depends on the operation of the planetary gears connected to it, and the rotation of the planetary gears depends on the meshing gear discs. Therefore, the stability of the gear disc assembly with the gear discs will affect the stability and accuracy of the stirring shovel's rotation. Based on this, in this technical solution, by setting protrusions and connecting grooves on the gear disc assembly and the electrical control box assembly respectively, and setting a specific-shaped retaining plate and elastic mounting component inside the protrusion, a relatively stable connection can be established between the gear disc assembly, the pot lid assembly, and the electrical control box assembly through the cooperation between the first and second protrusions of the retaining plate and the elastic mounting component, thereby enhancing the operational stability of the gear disc assembly.

[0030] Furthermore, considering the safety hazards of cleaning the control box assembly, the above design facilitates the cleaning of the cooking blender. Before cleaning, by pinching the first protrusion of the two clamping plates, the elastic mounting member is compressed, causing the clamping plates at both ends of the elastic mounting member to gradually move closer. At the same time, the second protrusion located at the other end of the clamping plates will also gradually move closer and disengage from the groove of the control box assembly. From this point on, only the gear plate assembly and the lid assembly can be cleaned without having to clean the control box assembly as well.

[0031] As a further preferred embodiment, the elastic mounting component includes a spring and a guide post correspondingly disposed on the inner wall of the groove that abuts against the clamping plate, for fixing the end of the spring; the clamping plate is provided with a guide hole for the guide post to pass through.

[0032] As described above, to balance the ease of cleaning and disassembly of the cooking blender with the stability of the gear assembly installation, this technical solution provides a preferred option for a flexible mounting component. By incorporating guide posts, guide holes, and springs, the position of the clamping plates within the grooves can be precisely controlled, thus providing a stable foundation for the normal meshing and operation of the planetary gears of the mixing spatula. Furthermore, this design simultaneously increases the stability of disassembly of the control box assembly and the gear assembly. When the first protrusions of the two clamping plates are engaged, the guide post design limits the degree of freedom of movement of the clamping plates, ensuring they move along the axial direction of the guide post and preventing the plates from shifting. Therefore, disassembly is smoother and more efficient.

[0033] As a further preferred embodiment, the first protrusion is disposed in the middle of the lower end of the card plate; surrounding the groove, the lower surface of the gear disk assembly is also provided with a limiting protrusion for defining the position of the first protrusion.

[0034] In principle, the secure mounting of the clamping plate to the electrical control box assembly and gear disk assembly can be achieved by setting guide posts, guide holes, and springs. This technical solution, by providing a limiting protrusion on the lower surface of the gear disk assembly, further restricts the position of the clamping plate, thus increasing the stability of the gear disk assembly. Furthermore, the above design also limits the sliding position at the lower end of the clamping plate. Therefore, after the first protrusion of the two clamping plates is engaged, the first protrusion and both ends of the clamping plate will slide closer together along the inner wall of the limiting protrusion, resulting in greater stability and smoothness in disassembly.

[0035] As a further preferred embodiment, the lower surface of the defined protrusion is detachably connected to a lower pressure plate for sealing the groove; the distance between the first protrusions of the two clamping plates is greater than the length of the lower pressure plate along the guide post direction.

[0036] In this technical solution, by providing a pressure plate on the lower surface of the defined protrusion, the position of the clamping plate is further defined, increasing the connection strength between the gear disk assembly and the electrical control box assembly, thereby improving the stability of the stirring spatula's rotation. Furthermore, the pressure plate effectively prevents the internal splashing of cooking ingredients, and its detachable design allows users to clean it periodically. In addition, the distance between the aforementioned first protrusions refers to the distance between the ends of the first protrusions furthest from the groove. Considering that the design of the pressure plate will affect the ease of closing the first protrusions, this technical solution also designs the dimensions of the first protrusions and the pressure plate, achieving a balance between cleanliness and ease of disassembly.

[0037] As a further preferred embodiment, the groove includes an upper pressure plate that is correspondingly disposed to the lower pressure plate and detachably connected to the side wall of the groove, and the upper pressure plate is connected to the upper end of the second protrusion.

[0038] In principle, in designs using only a lower pressure plate, the groove can be thoroughly cleaned by disassembling the lower pressure plate, the elastic mounting component, and the clamping plate. However, this technical solution, by incorporating a flexibly removable upper pressure plate, allows users to more comprehensively clean blind spots such as the inner wall of the groove and the end of the guide post furthest from the groove opening after disassembly. Furthermore, this technical solution further reduces the ease of cleaning at the location where the clamping plate is penetrated by the second protrusion by adjusting the connection between the upper pressure plate and the second protrusion, thus offering excellent practicality.

[0039] As a further preferred embodiment, the elastic mounting members are configured in two sets, respectively disposed at both ends of the clamping plate; both the lower pressure plate and the upper pressure plate are provided with through holes in the middle for the drive shaft to pass through.

[0040] By setting two sets of guide posts, guide holes, and springs at both ends of the clamping plate, the stability of the clamping plate can be increased. Therefore, the first and second protrusions on both sides of the clamping plate can better engage with the limiting protrusions on the surface of the gear disk assembly and the grooves on the electrical control box assembly, resulting in a tighter connection between the gear disk assembly, the electrical control box assembly, and the pot lid assembly. This means that the gear disk assembly will be firmly fixed to the lower surface of the pot lid assembly, that is, the positions of the large and small gear disks are relatively fixed, thus the meshing stability of the planetary gears meshing with it is higher, and the corresponding rotation and stirring of the stirring spatula is also more stable. In addition, in this technical solution, by providing through holes in the middle of the lower and upper pressure plates for the drive shaft to pass through, the position of the drive shaft can be limited.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] This application, through the coordination of the structure, position, and installation relationship of the mixing spatula, adjusting components, gear disk assembly, and planetary gears, breaks through the barriers of the limitations of the application scenarios of mixers proposed in the background technology, increases the diversity of mixing power parameters, can meet the various mixing and cooking needs of users, fundamentally realizes one machine for multiple uses, reduces the economic and space-consuming burden of purchasing multiple models of machines for users, and has extremely high practicality.

[0043] This application also establishes a relatively stable sliding connection between the stirring rod and the sleeve by setting up a stirring rod, a sleeve head, and a fixing module, giving the stirring rod the function of extending and retracting along the axial direction of the sleeve head. It can be seen that, based on the horizontal adjustment of the stirring spatula position by the adjusting component, the stirring spatula can also stir ingredients at different depths within the cooking vessel, further increasing the stirring surface area of ​​the blades. Therefore, the stirring spatula can better and more fully cover the ingredients inside the entire cooking vessel, resulting in higher overall stirring flexibility and better stirring effect.

[0044] This application, by setting protrusions and connecting grooves on the gear disk assembly and the electrical control box assembly respectively, and setting a specifically shaped retaining plate and elastic mounting component inside the protrusion, utilizes the cooperation between the first and second protrusions of the retaining plate and the elastic mounting component to establish a relatively stable connection between the gear disk assembly, the lid assembly, and the electrical control box assembly, thereby enhancing the operational stability of the gear disk assembly. This means that the planetary gear meshing with the large or small gear disk of the gear disk assembly has higher operational stability, and the stirring spatula's rotational stirring effect is better. Furthermore, this application, through the design of the positioning slide and the structure and position of the adjusting component, greatly simplifies the user's convenience in installing and switching between different stirring modes of the cooking mixer.

[0061] The present application will be further described below with reference to specific embodiments. Those skilled in the art will be able to implement the present application based on these descriptions. Furthermore, the embodiments of the present application described below are generally only a part of the embodiments of the present application, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort should fall within the scope of protection of the present application.

[0062] Example

[0063] Please see Figures 1-14 This embodiment discloses a cooking blender, comprising:

[0064] A cooking dish 1, a lid 2 for fastening onto the cooking dish 1, and a stirring component 3 disposed on the lower surface of the lid 2 for stirring the ingredients inside the cooking dish 1; the stirring component 3 includes a stirring spatula 31 and an adjusting assembly 32 for adjusting the horizontal position of the stirring spatula 31; the adjusting assembly 32 includes a fixing member 321 for fixing the stirring component 3, a telescopic member 322 slidably connected to the fixing member 321, and a locking member 323 for adjusting the relative position between the fixing member 321 and the telescopic member 322; the telescopic member 322 is located away from the fixing member 321. The stirring component 3 is provided with a mounting plate 3221 at one end; the stirring component 3 also includes a planetary gear 33 disposed on the upper surface of the mounting plate 3221, and a mounting platform 331 for mounting the stirring shovel 31 is provided on the lower surface of the planetary gear 33, which penetrates the mounting plate 3221; the cover 2 includes a gear disk assembly 21, which includes a large gear disk 211 that meshes internally with the planetary gear 33, and a small gear disk 212 that meshes externally with the planetary gear 33; the cover 2 also includes a drive shaft that penetrates the middle of the small gear disk 212 and is connected to the fixing member 321 for driving the stirring component 3 to rotate. In this embodiment, by first setting an adjustment component 32 on the stirring shovel 31, the stirring shovel 31 is given the function of extending and retracting along the direction of the adjustment component 32 by the cooperation of the telescopic member 322, the fixing member 321 and the locking member 323, thereby increasing the stirring surface of the stirring shovel blade. Based on this, by setting two different diameter large gear discs 211 and small gear discs 212, they can cooperate with the telescopic component 322 to adjust the meshing position of the planetary gear 33, thereby meeting different stirring requirements. In addition, by replacing the planetary gear 33, the rotation speed of the stirring shovel 31 can be further adjusted, resulting in high stirring flexibility and a wider range of applications.

[0065] The cooking mixer of this application can adjust the stirring rotation speed of the stirring spatula 31 by replacing the planetary gears 33 of different diameters. However, when replacing the planetary gears 33, the user needs to first separate the fixing part 321 from the drive shaft. Therefore, if the installation between the fixing part 321 and the drive shaft is complicated, it will increase the difficulty of adjusting the stirring. Therefore, in this embodiment, the fixing member 321 includes a swing arm groove 3211 with an opening on one side, and the opening side of the swing arm groove 3211 is used for sliding connection with the telescopic member 322; the fixing member 321 also includes a swing arm cover 3212 covering the swing arm groove 3211 and used to prevent the telescopic member 322 from falling off; the swing arm groove 3211 includes an inner groove surface 32111 corresponding to the swing arm cover 3212, and a boss 32112 is provided on the inner groove surface 32111. A magnet is embedded in the side of the boss 32112 near the swing arm cover 3212, and a transmission end for installing a drive shaft is provided at the end of the boss 32112 away from the magnet. This embodiment fully utilizes the inner groove surface 32111, on which a boss 32112 is provided, with magnets and transmission ends respectively at both ends of the boss 32112. This design greatly simplifies the assembly and disassembly steps between the fixing component 321 and the drive shaft. While ensuring the adjustment component 32's function of adjusting the horizontal position of the stirring spatula 31, it further enhances the convenience of flexible adjustment of stirring parameters. Specifically, during installation, simply bring the drive shaft close to the transmission end of the boss 32112, and the magnet installed in the boss 32112 will form a tight connection with it through magnetic attraction. At this time, the magnet can lift the stirring component 3 through the magnetic attraction between itself and the drive shaft, completing the installation of the stirring component 3.

[0066] To further simplify the structural design of the adjustment component 32, in this embodiment, the telescopic member 322 further includes two parallel telescopic arms 3222 that slide in contact with the inner wall of the swing arm groove 3211 and are used to move the mounting plate 3221. The inner groove surface 32111 is also provided with a limiting protrusion 32113 that slides in contact with the telescopic arms 3222 and is used to limit the position of the telescopic arms 3222. This embodiment controls the dimensions of the telescopic arms 3222 and the inner wall of the swing arm groove 3211, and can directly limit the sliding position relationship between the two without setting up complicated components. The structural design is relatively simple and easy to operate. On this basis, in order to avoid deviations in the manufacturing process of the swing arm groove 3211 and the telescopic arms 3222 and increase the stability of the telescopic arms 3222 sliding in the swing arm groove 3211, this technical solution also provides a limiting protrusion 32113 on the inner groove surface 32111. Therefore, during the use of the cooking mixer under this technical solution, by sliding the telescopic arm 3222 and adjusting the length of the telescopic arm 3222 built into the swing arm groove 3211, the horizontal position of the stirring shovel 31 set on the mounting plate 3221 can be adjusted, thereby making the planetary gear 33 connect with the large gear plate 211 or the small gear plate 212, and finally realizing the eccentric stirring motion of the stirring shovel 31 at different positions.

[0067] To limit the sliding range of the telescopic arm 3222 within the swing arm groove 3211 and avoid the technical problem of difficult engagement and installation of the planetary gear 33 caused by the telescopic arm 3222 being too long or too short within the swing arm groove 3211, in this embodiment, the ends of the two telescopic arms 3222 away from the mounting plate 3221 are connected to each other to form an anti-disengagement arm 3223 to prevent the telescopic component 322 from disengaging from the swing arm groove 3211; a baffle plate 3224 is provided on the side of the two telescopic arms 3222 near the mounting plate 3221 to prevent the mounting plate 3221 from sliding into the swing arm groove 3211. Furthermore, the technical solution of setting the baffle plate 3224 can also avoid the collision between the stirring shovel 31 and the fixing component 321 during the sliding of the telescopic arm 3222, thus making the design of the stirring component 3 more reasonable and reliable.

[0068] The locking component 323 includes a locking protrusion 3231 disposed on the inner groove surface 32111, and a lead screw 3232 disposed at one end on the locking protrusion 3231. The other end of the lead screw 3232 passes through the anti-detachment arm 3223 and the swing arm groove 3211 sequentially along the extension direction of the telescopic component 322. A tightening plate 3233 is provided at one end of the locking component 323 passing through the swing arm groove 3211. The locking component 323 also includes a nut 3234 sleeved on the outer surface of the lead screw 3232 for driving the anti-detachment arm 3223 to move along the lead screw 3232. In this embodiment, through the design of the positional relationship and structure between the lead screw 3232, the locking protrusion 3231, the nut 3234, the tightening plate 3233 and the anti-detachment arm 3223, the meshing position of the planetary gear 33 can be adjusted, ultimately realizing multi-mode stirring of the ingredients in the cooking dish 1. Specifically, the user can manually turn the screw 3232 by turning the screw plate 3233, thereby driving the anti-detachment arm 3223 to move along the screw 3232 through the nut 3234 that cooperates with the screw 3232, and adjusting the length of the telescopic arm 3222 built into the swing arm groove 3211.

[0069] To further increase the stirring range of the stirring spatula 31, in this embodiment, the stirring spatula 31 includes a stirring rod 311 with blades and a sleeve 312 axially slidably connected to the end of the stirring rod 311 away from the blades. The stirring spatula 31 also includes a fixing module 313 for fixing the relative position of the stirring rod 311 and the sleeve 312. This embodiment establishes a relatively stable sliding connection between the stirring rod 311 and the sleeve 312 by setting the stirring rod 311, the sleeve 312, and the fixing module 313, giving the stirring rod 311 the function of axial extension and retraction along the sleeve 312. Therefore, based on the horizontal adjustment of the stirring spatula 31 position by the adjusting component 32, the length of the stirring spatula 31 can be further adjusted. This design can cooperate with the adjusting component 32 to further increase the stirring surface of the blades. Therefore, the stirring spatula 31 can better and more fully cover the ingredients inside the entire cooking dish 1, resulting in higher overall stirring flexibility and better stirring effect for the stirring component 3.

[0070] Since the stirring spatula 31 needs to rotate continuously during use, the stability of the fixing module 313 directly affects the stirring effect of the telescopic stirring spatula 31 and even cooking safety. Therefore, the fixing module 313 includes a mounting slot 3131 correspondingly extending through the surfaces of the stirring rod 311 and the sleeve 312, and a connector 3132 cooperating with the mounting slot 3131. The connector 3132 includes a first connector 31321 extending through the mounting slot 3131 and a second connector 31322 cooperating with the first connector 31321. In this embodiment, by providing the mounting slot 3131 and the cooperating connector 3132, the first connector 31321 and the second connector 31322 can correspondingly fix the mounting slot 3131 of the stirring rod 311 and the sleeve 312. In this embodiment, the mounting slot 3131 is a single, centrally located slot; the first connector is a bolt, and the second connector is a nut.

[0071] During the adjustment of the length of the stirring spatula 31, the user needs to first rotate and adjust the stirring rod 311 and the sleeve 312 so that their mounting slots 3131 correspond before the connector 3132 can be installed. To save the above adjustment steps and increase the convenience of adjusting the blade stirring interface, in this embodiment, the surfaces of the stirring rod 311 and the sleeve 312 are respectively provided with positioning grooves 314, and the mounting slots 3131 are set on the positioning grooves 314.

[0072] The rotation of the stirring spatula 31 depends on the operation of the planetary gear 33 connected to it. The rotation of the planetary gear 33 depends on the meshing of the gear disk. Therefore, the stability of the gear disk assembly 21 with the gear disk will affect the stability and accuracy of the stirring spatula 31's rotation. In this embodiment, the cover 2 also includes a pot lid assembly 22 and an electrical control box assembly 23 that are sequentially connected to the upper surface of the gear disk assembly 21. A groove 213 is provided at the center of the small gear disk 212 protruding from the upper surface of the small gear disk 212, and the opening of the groove 213 faces downward. The lower surface of the electrical control box assembly 23 is provided with a connecting groove 231 for installing the groove 213. The groove 213 penetrates the pot lid assembly 22 and is connected to the inner wall of the connecting groove 231. 13 A pair of inner walls abut against a retaining plate 214, and an elastic mounting member 215 is provided between the retaining plates 214 for abutting against the inner wall of the groove 213; the lower end of the retaining plate 214 is provided with a first protrusion 2141 that connects with the lower surface of the gear disk assembly 21, and the upper end of the retaining plate 214 is provided with a second protrusion 2142 that penetrates the inner wall of the groove 213; the side wall of the connecting groove 231 is provided with a groove 2311 that engages with the second protrusion 2142. In this embodiment, by providing a protrusion 213 and a connecting groove 231 on the gear disk assembly 21 and the electrical control box assembly 23 respectively, and by providing a specific shaped clamping plate 214 and an elastic mounting member 215 inside the protrusion 213, a relatively stable connection relationship can be established between the gear disk assembly 21, the pot lid assembly 22 and the electrical control box assembly 23 through the cooperation between the first protrusion 2141 and the second protrusion 2142 of the clamping plate 214 and the elastic mounting member 215, thereby enhancing the operational stability of the gear disk assembly 21.

[0073] To balance ease of cleaning and disassembly of the cooking mixer with the stability of the gear assembly 21, the elastic mounting component 215 in this embodiment includes a spring 2151 and a guide post 2152 correspondingly disposed on the inner wall of the groove 213 that abuts against the clamping plate 214, for fixing the end of the spring 2151; the clamping plate 214 is provided with a guide hole 2153 for the guide post 2152 to pass through. By providing the guide post 2152, guide hole 2153, and spring 2151, this embodiment allows for precise control of the position of the clamping plate 214 inside the groove 213, thus providing a stable foundation for the normal meshing operation of the planetary gear 33 of the mixing spatula 31. In addition, the above design will simultaneously increase the stability of disassembly of the electrical control box assembly 23 and the gear disk assembly 21. When the first protrusion 213 of the two clamping plates 214 is pinched together, the design of the guide post 2152 will limit the degree of freedom of movement of the clamping plate 214, so that it moves along the axial direction of the guide post 2152, avoiding the occurrence of the clamping plate 214 moving around. Therefore, the disassembly is smoother and more efficient.

[0074] In principle, by setting guide posts 2152, guide holes 2153, and springs 2151, the clamping plate 214 can be stably installed on the electrical control box assembly 23 and the gear disk assembly 21. In this embodiment, to further limit the position of the clamping plate and increase the stability of the gear disk assembly, the first protrusion 2141 is set in the middle of the lower end of the clamping plate 214; around the groove 213, the lower surface of the gear disk assembly 21 is also provided with a limiting protrusion 216 for limiting the position of the first protrusion 2141. In addition, the above design can also limit the sliding position at the lower end of the clamping plate 214. Therefore, after the first protrusion 2141 of the two clamping plates 214 is pinched together, the first protrusion 2141 and the two ends of the clamping plate 214 will slide closer to each other along the inner wall of the limiting protrusion 216, which shows that the disassembly is more stable and smoother.

[0075] To further define the position of the clamping plates and increase the connection strength between the gear disk assembly and the electrical control box assembly, thereby improving the stability of the stirring spatula's rotation, in this embodiment, a lower pressure plate 217 for sealing the groove 213 is detachably connected to the lower surface of the defined protrusion 216. The distance between the first protrusions 2141 of the two clamping plates 214 is greater than the length of the lower pressure plate 217 along the guide post 2152. The lower pressure plate 217 can effectively prevent the internal splashing of cooking ingredients, and its detachable design can meet the user's need for regular cleaning. In addition, this embodiment also fully considers that the design of the lower pressure plate 217 will affect the ease of pinching the first protrusion 2141, and designs the dimensions of the first protrusion 2141 and the lower pressure plate 217 to achieve a balance between cleanliness and ease of disassembly.

[0076] In principle, the groove 213 can be thoroughly cleaned by disassembling the lower pressure plate 217, the elastic mounting part 215, and the clamping plate 214. However, in this embodiment, the groove 213 also includes an upper pressure plate 218 corresponding to the lower pressure plate 217 and detachably connected to the side wall of the groove 213. The upper pressure plate 218 is connected to the upper end of the second protrusion 2142. Therefore, after disassembly, the user can perform a more comprehensive cleaning of the blind areas such as the inner wall of the groove 213 and the end of the guide post 2152 away from the groove opening. Based on this, the design of the connection between the upper pressure plate 218 and the second protrusion 2142 further reduces the ease of cleaning at the position where the clamping plate 214 is penetrated by the second protrusion 2142, thus making it extremely practical.

[0077] Furthermore, in this embodiment, the elastic mounting members 215 are configured in two sets, respectively disposed at both ends of the clamping plate 214; the lower pressure plate 217 and the upper pressure plate 218 are both provided with through holes for the drive shaft to pass through. By providing two sets of guide posts 2152, guide holes 2153 and springs 2151 at both ends of the clamping plate 214, the stability of the clamping plate 214 can be increased. Therefore, the first protrusion 2141 and the second protrusion 2142 disposed on both sides of the clamping plate 214 can be better engaged in the limiting protrusion 216 on the surface of the gear disk assembly 21 and the groove 2311 on the electrical control box assembly 23. Thus, the connection between the gear disk assembly 21, the electrical control box assembly 23, and the pot lid assembly 22 is more tightly secured. This means that the gear assembly 21 will be firmly fixed to the lower surface of the lid assembly 22, that is, the positions of the large gear 211 and the small gear 212 are relatively fixed, thus the meshing stability of the planetary gear 33 that meshes with it is higher, and the rotation and stirring of the corresponding stirring spatula 31 is also more stable. In addition, by providing through holes in the middle of the lower pressure plate 217 and the upper pressure plate 218 for the drive shaft to pass through, the position of the drive shaft can be defined.
