Description

Technical Field

[0001] This application relates to the field of household appliances, and more specifically, to a blending device and a food processor using the blending device. Background Technology

[0002] Food processors, such as soymilk makers, blenders, high-speed blenders, dough mixers, or blending kettles, are household appliances that crush and blend food. They process ingredients in a container using a blending device. In related technologies, taking soymilk makers and high-speed blenders as examples, their blending devices include a blade shaft and a stirring blade mounted on it. Typically, the stirring blade is fixed to the blade shaft and cannot be removed. Therefore, the space inside the container, especially in the area where the blending device is installed, can easily become a difficult area to clean due to the presence of the stirring blade. Utility Model Content

[0003] This application provides a blending device and a food processor, which are designed to make the blending device detachable to improve the ease of cleaning the food processor.

[0004] This application provides a stirring device, including a stirring component, a rotating shaft, and a locking assembly. The stirring component includes a bushing and a stirring part connected to the bushing. A drive groove is provided inside the bushing, and a mounting hole communicating with the drive groove is provided on the side wall of the bushing. The rotating shaft is adapted to be assembled in the drive groove and drive the agitator to rotate together. The rotating shaft includes a drive section and a connecting section. The drive section is connected to the front end of the connecting section in the insertion direction of the rotating shaft. A limiting surface is provided at the end of the drive section connected to the connecting section. The locking assembly is mounted on the bushing and extends at least partially into the drive groove through the mounting hole. The locking assembly is used to stop the limiting surface in the direction of disengagement from the drive groove after the rotating shaft is inserted into the drive groove, and to avoid the limiting surface during operation so that the rotating shaft can disengage from the drive groove.

[0005] In some embodiments, the locking assembly includes a locking member that engages with the stop of the limiting surface, the locking member being movably disposed in the mounting hole, a portion of the locking member extending out of the mounting hole and located outside the bushing for operation.

[0006] In some embodiments, the locking member is rotatably connected to the bushing via a pivot, and when the locking member is operated, the portion of the locking member located within the drive groove rotates about the pivot to move to the outside of the limiting surface.

[0007] In some embodiments, the locking assembly further includes an elastic element that provides an elastic force acting on the locking member to hold the locking member in a position that blocks the limiting surface, and, when the locking member is operated, overcomes the elastic force to move the locking member about the pivot to the outside of the limiting surface.

[0008] In some embodiments, the outer wall of the bushing is formed with a mounting groove that communicates with the mounting hole. Part of the elastic element is fixed in the mounting groove, and another part of the elastic element extends into the mounting hole and elastically acts on the locking element.

[0009] In some embodiments, the elastic element is a ring-shaped structure, and the mounting groove is an annular groove.

[0010] In some embodiments, at least two locking members are provided and are spaced apart in the circumferential direction of the bushing, and the mounting holes are provided in one-to-one correspondence with the locking members; The elastic element acts elastically on at least two of the locking elements together.

[0011] In some embodiments, the locking element is a sheet-like structure, and the opening shape of the mounting hole is adapted to the form of the locking element.

[0012] In some embodiments, the portion of the locking member located on the outer side of the bushing has a radial dimension ranging from 2 mm to 10 mm along the bushing.

[0013] In some embodiments, the outer surface of the bushing is provided with an annular groove, and the mounting hole is formed in the annular groove.

[0014] In some embodiments, the cross-section of the drive segment is polygonal, and the cross-sectional shape of the portion of the drive groove corresponding to the drive segment is adapted to the drive segment; And / or, the top of the bushing is provided with a connecting hole that communicates with the drive groove; And / or, the locking member is located above the agitator.

[0015] This application also provides a food processor, including a main unit, a blending cup assembly, and a blending device as described above. The blending device is disposed at the bottom of the blending cup assembly and can be driven by the main unit.

[0016] The mixing device based on this application provides a mounting hole on the bushing that communicates with the drive groove, and a locking component is provided at the mounting hole. When the rotating shaft is installed in the drive groove, the locking component limits the limiting surface in the direction of the rotating shaft's disengagement. The locking component can be operated to allow it to avoid the limiting surface in the direction of the rotating shaft's disengagement from the drive groove, thereby allowing the rotating shaft to disengage from the drive groove. This enables the mixing device to be disassembled and reassembled. For food processors using the mixing device of this application embodiment, after processing the ingredients, the mixing component can be removed from the bottom of the food processor's mixing cup assembly, making it easier to clean the bottom space of the mixing cup assembly. This greatly reduces the possibility of unsanitary corners, thereby improving hygiene and safety.

[0017] Furthermore, in this embodiment, the locking component blocks the limiting surface to combine the rotating shaft and the bushing. During disassembly, the locking structure can be operated to avoid the limiting surface. It is understood that the limiting surface is easy to form during the rotating shaft machining process by ordinary turning or integral casting. Such a structure is also relatively simple and the manufacturing cost is relatively low. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] The first aspect of this application provides a food processor, which can be a soy milk maker, blender, high-speed blender, dough mixer, or electric kettle, etc.

[0023] Please see Figures 1-2 The food processor 1001 includes a main unit 10, a blending cup assembly 20, a cup lid 30, and a blending device 40.

[0024] Specifically, the main unit 10 may include a motor, a control panel (not shown), and a circuit system. The main unit 10 also includes a housing 11, within which the main structure of the motor and the circuitry are housed. The control panel can be mounted on the outer surface of the housing 11. The motor has a motor shaft 121, which provides power to the blending device 40. The control panel provides an interactive interface between the user and the blender 100, allowing the user to set the blender's operating mode, adjust the speed, and perform other functions.

[0025] The mixing cup assembly 20 is driven and connected to the main unit 10. In one embodiment, the mixing cup assembly 20 includes a mixing cup 21 and a base. The mixing cup 21 and the base can be connected by threads or screws, etc., which is not specifically limited in this embodiment. The mixing cup 21 can be used to hold food to be mixed. To facilitate the user in taking and putting away the mixing cup 21, the mixing cup assembly 20 may also include a handle. The handle is firmly connected to the outer wall of the mixing cup 21, conforms to human grip habits, and can effectively improve the convenience of operation. The mixing cup 21 may be cylindrical and made of transparent materials, such as transparent plastic or high borosilicate glass, so that the user can clearly and intuitively observe the processing status of the ingredients at any time during the operation of the food processor 100, such as the degree of crushing and mixing state of the ingredients, thereby better controlling the cooking progress.

[0026] Furthermore, the blending cup 21 has an opening, and the lid 30 can cover the blending cup assembly 20, so that the lid 30 can seal the opening and cooperate with the blending cup 21 to form a blending chamber 20a. The lid 30 seals the opening to prevent food from splashing out of the blending chamber 20a, thereby preventing food waste and reducing the probability of food soiling the outer surface of the food processor 100 or the countertop where the food processor 100 is placed, thus improving the user's cleaning convenience and user experience.

[0027] The mixing device 40 is located at the bottom of the mixing cup assembly 20; that is, the mixing device 40 is connected to the chassis. The mixing cup assembly 20 is mounted on the main unit 10; the mixing cup assembly 20 is electrically connected to the main unit 10. The motor shaft 121 of the motor is driven by the rotating shaft 44; that is, the rotating shaft 44 can pass through the chassis and be driven by the motor shaft 121 to drive the mixing device 40 to stir or crush the food to be mixed in the mixing chamber 20a. The output power of the motor can be precisely controlled by the circuit system of the main unit 10 to flexibly adjust the operating state of the mixing device 40 so that it can adapt to various food preparation programs. Of course, in other embodiments, the mixing device 40 can also be driven by magnetic force, that is, the rotating shaft 44 is not directly connected to the motor shaft 121 of the motor, but each of them is provided with a disk, and the two are connected by non-contact transmission through the cooperation of the disks.

[0028] Furthermore, the food processor 100 of this application may also have a heating function. In some embodiments, the blending cup assembly 20 may further include a heating module (not shown), which is used to heat the ingredients in the blending chamber 20a. The heating method of the heating module may be at least one of resistance heating, infrared heating, and electromagnetic heating. In this application embodiment, the specific heating method of the heating module is not limited. It is understood that the installation position of the heating module may be at least one of the base and the periphery of the blending cup 21. In this application embodiment, the installation position of the heating module is not limited.

[0029] In other embodiments, the food processor 100 may also have structures such as temperature detection and installation detection on the blending cup assembly 20. That is, after the blending cup assembly 20 is installed on the host 10, the host 10 can activate these temperature detection and installation detection structures, thereby driving the blending cup assembly 20 in the circuit.

[0030] Based on the above, since the mixing device 40 is installed at the bottom of the mixing cup 21, it occupies most of the bottom space of the mixing cup 21. After the food is processed, if the user wants to clean the entire mixing cup 21, the interference of the mixing device 40 makes the cleaning process inconvenient and easily creates unsanitary corners.

[0031] Therefore, please refer to the following: Figures 3 to 5 In another aspect, this application provides a mixing device 40. By forming the mixing device 40 into a detachable structure, the entire cleaning process is more convenient, and it is less likely to leave any dead corners, thereby improving the hygiene and safety of the food processor 100.

[0032] The agitation device 40 includes an agitator 41, a rotating shaft 44, and a locking assembly 45. The agitator 41 includes a bushing 42 and an agitator 43 connected to the bushing 42. A drive groove 421 is provided inside the bushing 42, wherein the drive groove 421 is open at its lower end for the rotating shaft 44 to be inserted into the drive groove 421. A mounting hole 422 communicating with the drive groove 421 is provided on the side wall of the bushing 42. In this embodiment, the upper end of the drive groove 421 can be connected to the outside, for example, a connecting hole 425 is provided on the top of the bushing 42. The connecting hole 425 facilitates the discharge of gas in the drive groove 421 to the outside during the process of the rotating shaft 44 being inserted into the drive groove 421, thereby releasing pressure. This makes the assembly operation of the rotating shaft 44 and the drive groove 421 easier to achieve. Of course, this arrangement also facilitates the subsequent cleaning operation.

[0033] The rotating shaft 44 is drivenly connected to the motor shaft 121 and is adapted to be assembled in the drive groove 421, driving the agitator 41 to rotate together. The rotating shaft 44 includes a drive section 441 and a connecting section 442. The drive section 441 is connected to the front end (i.e., the upper end) of the connecting section 442 in the insertion direction of the rotating shaft 44. The end where the drive section 441 connects to the connecting section 442 is provided with a limiting surface 443. In this embodiment, the connecting section 442 of the rotating shaft 44 can be directly connected to the motor shaft 121 or connected through a coupling. When directly connected to the motor shaft 121, the rotating shaft 44 can be fixedly connected to the motor shaft 121 in a non-detachable manner, such as by welding, or even a part of the motor shaft 121 can be formed into the rotating shaft 44. When the rotating shaft 44 and the motor shaft 121 are detachably connected, one of the motor shaft 121 and the rotating shaft 44 can be provided with a threaded hole, while the other of the motor shaft 121 and the rotating shaft 44 can be provided with a threaded section, and the threaded section and the threaded hole can be threadedly engaged.

[0034] In this embodiment, the drive section 441 has a polygonal cross-section, and the portion of the drive groove 421 corresponding to the drive section 441 is also designed as a polygonal cross-section cavity. This allows the rotating shaft 44 to stably drive the bushing 42 to rotate together. In this embodiment, the outer diameter of the circumscribed circle of the drive section 441 is larger than the outer diameter of the circumscribed circle of the connecting section 442, thus forming a finite surface 443 at the end where the drive section 441 connects to the connecting section 442. This structural design is easy to implement on the rotating shaft 44 using existing processing techniques. Furthermore, it reduces the material usage of the rotating shaft 44, lowers costs, and simplifies the structure.

[0035] The bushing 42 can be made of high-strength, corrosion-resistant materials such as stainless steel and alloy steel, and this embodiment does not specifically limit its material. The mixing part 43 can be connected to the bushing 42 by non-removable methods such as welding, riveting, or pressing, so as to achieve a fixed connection between the mixing part 43 and the bushing 42. In addition, since the mixing device 40 can be applied to different types of food processors 100, the shape of the mixing part 43 can be varied; that is, the mixing part 43 can be a blade, a stirring rod, a grinding disc, etc. For example, when the mixing device 40 is applied to a soymilk maker, a blender, etc., the mixing part 43 can be provided with a blade. And depending on the nature of the food to be mixed and the purpose of mixing, the blade can be an inclined blade, a curved blade, a spiral blade, etc., and this embodiment does not specifically limit its material.

[0036] The locking assembly 45 is mounted on the bushing 42 and extends at least partially into the drive groove 421 through the mounting hole 422. The locking assembly 45 is used to stop the limiting surface 443 in the direction in which the rotating shaft 44 disengages from the drive groove 421 after the rotating shaft 44 is inserted into the drive groove 421, and to avoid the limiting surface 443 during operation so that the rotating shaft 44 can disengage from the drive groove 421.

[0037] Based on the mixing device 40 of this application, by providing a mounting hole 422 on the bushing 42 that communicates with the drive groove 421, and providing a locking component 45 at the mounting hole 422, when the rotating shaft 44 is installed in the drive groove 421, the locking component 45 limits the limiting surface 443 in the disengagement direction of the rotating shaft 44, and can be operated to make the locking component 45 avoid the limiting surface 443 in the direction in which the rotating shaft 44 disengages from the drive groove 421, thereby enabling the rotating shaft 44 to disengage from the drive groove 421. This allows the mixing device 40 to achieve a disassembly and assembly design. For the food processor 100 using the mixing device 40 of this application embodiment, after processing the food, the mixing component 41 can be removed from the bottom of the mixing cup assembly 20 of the food processor 100, thereby facilitating the cleaning of the bottom space of the mixing cup assembly 20. This greatly reduces the possibility of hygiene dead corners, thereby improving hygiene and safety.

[0038] Furthermore, in this embodiment, the locking component 45 blocks the limiting surface 443 to connect the rotating shaft 44 and the bushing 42. During disassembly, the locking structure can be operated to avoid the limiting surface 443. It is understood that the limiting surface 443 is easy to form during the machining process of the rotating shaft 44 by ordinary turning or integral casting. Such a structure is relatively simple and the manufacturing cost is relatively low.

[0039] It should be noted that in the agitator 40 provided in this embodiment, the agitator 43 is connected to the bushing 42 below the locking assembly 45. Therefore, please refer to the reference [reference needed]. Figure 1 , Figures 5 to 7 When it is necessary to remove the agitator 41 from the rotating shaft 44, the operator can insert the agitator cup assembly 20 downwards into the agitator chamber 20a, operate the locking assembly 45 above the agitator part 43, and further pull the bushing 42 of the agitator 41 upwards. Throughout the process, the agitator part 43 will not interfere with the operation, making the operation more convenient.

[0040] In some embodiments, the locking assembly 45 includes a locking member 46 for engaging with a stop on the limiting surface 443. The locking member 46 is movably disposed in the mounting hole 422, with a portion extending out of the mounting hole 422 and located outside the bushing 42 for operation. When disassembly of the agitator 40 is required, the agitator 41 is primarily separated from the rotating shaft 44. In this case, the operator can operate on the exposed portion to allow the locking member 46 to avoid obstructing the limiting surface 443, thereby separating the agitator 41 from the rotating shaft 44. It is understood that in other structural forms, the locking member 46 may not be exposed outside the bushing 42; in this case, a tool can be used to insert into the mounting hole 422 to drive the locking member 46.

[0041] Furthermore, the locking member 46 is rotatably connected to the bushing 42 via a pivot 47. When the locking member 46 is operated, the portion of it located within the drive groove 421 rotates around the pivot 47 to move to the outside of the limiting surface 443. Specifically, pivots 47 can be provided on opposite sides of the locking member 46, and shaft holes are provided on the two opposite groove walls of the bushing 42 located in the mounting hole 422, with the pivots 47 rotatably disposed within the shaft holes.

[0042] Of course, the movement of the locking member 46 can be either rotational or sliding. For example, the mounting hole 422 is a hole extending radially in the bushing 42. The locking member 46 slides axially along the mounting hole 422 to partially extend into the lower position of the limiting surface 443 to block the limiting surface 443, or moves to the outside of the limiting surface 443 to avoid the limiting surface 443.

[0043] The following content will continue to explain the solution of this application by referring to the movement of the locking member 46 as rotation.

[0044] Please continue to refer to Figures 2 to 5 In one embodiment, the locking assembly 45 further includes an elastic member 48, which provides an elastic force acting on the locking member 46 to keep the locking member 46 in a position that blocks the limiting surface 443. When the locking member 46 is operated, the elastic force is overcome so that the locking member 46 moves about the pivot 44 to the outside of the limiting surface 443 to avoid the limiting surface 443.

[0045] Understandably, since the locking member 46 of this application is rotatably connected to the bushing 42, during the process of the rotating shaft 44 being inserted into the drive groove 421, the rotating shaft 44 pushes the locking member 46 outward so that the drive section 441 passes through the position of the locking member 46, thereby causing the limiting surface 443 to move to the position above the locking member 46 in the drive groove 421. During this process, the elastic member 48 provides elastic force to reset the locking member 46 and keep the part of the locking member 46 in the drive groove 421 always in the position of blocking the limiting surface 443. This can better ensure that the mixing member 41 is not prone to separation from the rotating shaft 44 during the operation of the food processor 100, thereby ensuring the stability of the entire structure.

[0046] In one embodiment, the axial direction of the rotating shaft 44 of this application is approximately horizontal, that is, the locking member 46 rotates in a substantially vertical direction. In this configuration, the locking member 46 is a sheet-like structure with a thickness ranging from 2 mm to 4 mm. The mounting hole 422 is also a narrow, elongated hole extending axially and radially into the bushing 42. This configuration ensures that the locking member 46 has high structural strength, while also ensuring high overall structural integrity of the bushing 42, thus guaranteeing the structural strength of its foundation.

[0047] Of course, in other embodiments, the axis of the rotating shaft 44 can also be approximately vertical, meaning it is also possible for the locking member 46 to rotate in a generally horizontal direction. The following description will further elaborate on the assumption that the axis of the rotating shaft 44 is approximately horizontal.

[0048] When the locking member 46 is rotatably connected to the bushing 42, in order to ensure that the portion of the locking member 46 located in the drive groove 421 is always at the position of the blocking limiting surface 443 after the rotating shaft 44 is inserted into the drive groove 421 without operating the locking member 46, a counterweight can also be designed for the locking member 46. The counterweight is connected to the position of the locking member 46 below the rotating shaft 44. In this case, the elastic member 48 can be omitted.

[0049] With the elastic member 48 provided, the outer wall of the bushing 42 is further formed with a mounting groove 423, which communicates with the mounting hole 422. Part of the structure of the elastic member 48 is fixed in the mounting groove 423, and another part of the elastic member 48 extends into the mounting hole 422 and elastically acts on the locking member 46. When the locking member 46 is operated, the locking member 46 squeezes the elastic member 48, causing it to deform and enter the mounting hole 422.

[0050] The arrangement of the mounting groove 423 connecting to the mounting hole 422 in this embodiment reduces the obstruction of the structure on the bushing 42 to the locking member 46 during operation, thus making the operation smoother. Specifically, by connecting the mounting groove 423 to the mounting hole 422, the locking member 46 can be operated until its outer surface is basically parallel to the outer wall of the bushing 42. It should be noted that after the operation on the locking member 46 is canceled, the elastic member 48 will drive the part of the structure at the bottom of the locking member 46 located in the mounting hole 422 to retract. In this embodiment, the elastic member 48 is basically a structure similar to an elastic block or elastic sheet, and its deformation bending direction is the thickness direction of its own structure.

[0051] In one embodiment, the elastic element 48 is a ring-shaped structure, and the mounting groove 423 is an annular groove. In this embodiment, the elastic element 48 can be made of silicone, which is elastic and suitable for food processing. Of course, other materials that meet these properties can also be used. By setting it to a ring-shaped structure and making the mounting groove 423 an annular groove, the installation of the elastic element 48 is facilitated.

[0052] Furthermore, at least two locking elements 46 are provided and are arranged at intervals in the circumferential direction of the bushing 42, and the mounting holes 422 are provided one-to-one with the locking elements 46; wherein, the elastic element 48 acts elastically on at least two locking elements 46 together.

[0053] exist Figures 3 to 5 As exemplarily shown, two locking members 46 are symmetrically arranged in the circumferential direction of the bushing 42. In this way, while the limiting surface 443 is limited relatively stably by the two locking members 46, it is also convenient to apply force to both locking members 46 simultaneously with one hand, making the unlocking operation more convenient.

[0054] It is understood that, in addition to the embodiments described above, the elastic element 48 can also be a spring, torsion spring, or other structure. When there are at least two locking elements 46, the number of elastic elements 48 in the form of springs or torsion springs corresponds to the number of locking elements 46.

[0055] In one embodiment, please refer to Figure 5 With the rotating shaft 44 assembled into the drive groove 421, the portion of the locking member 46 located on the outer side of the bushing 42 has a radial dimension D along the bushing 42, where D ranges from 2 to 10 millimeters, for example, 2 millimeters, 3 millimeters, 4 millimeters, 5 millimeters, 6 millimeters...10 millimeters. This configuration ensures a good fit to the bushing 42 while also guaranteeing an effective operating stroke and stable switching between different states.

[0056] In one embodiment, the outer surface of the bushing 42 is provided with an annular groove 424, and the mounting hole 422 is formed in the annular groove 424. Through the design of the annular groove 424, this embodiment makes the structure of the entire stirring device 40 more compact, and the annular groove 424 also provides the operator with convenient gripping for pulling the stirring component 41 upward, making the disassembly and assembly of the stirring component 41 simpler.

[0057] In addition, the portion of the locking member 46 located on the outer side of the bushing 42 is formed as a wedge structure extending obliquely downward. Thus, the locking member 46 also has a certain cutting function. During the rotation of the mixing member 41, the exposed portion of the locking member 46 can cut and turbulent the food close to the bushing 42, thereby improving the mixing and pulverizing effect within the mixing cup assembly 20.

In the description of this application, it should be understood that if terms such as "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this application 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, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
