Description

Technical Field

[0001] The present invention relates to the technical field of food processing devices, and in particular to a food processing utensil. Background Art

[0002] Food processing appliances currently on the market, such as grinders and soymilk machines, usually require a motor to drive the rotating shaft to run at high speed, thereby driving the grinding mechanism or stirring mechanism to rotate. However, in the prior art, the motors of some food processing appliances are fixed with a bracket. Due to the large rigidity of the bracket, the bracket and the motor are hard-connected, which results in insufficient buffer elasticity, making it easy for the motor vibration to be transmitted to other parts through the bracket. In addition, the fixing position of the bracket and the motor is often set at the middle and lower part or the bottom of the motor, which is far away from the motor shaft, so that the motor shaft at the free end shakes more during rotation, and the shaking of the motor shaft is easily transmitted to other parts, thereby increasing the vibration amplitude of the whole machine. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that the vibration of the motor of the food processing appliance is easily transmitted outward and the motor shaft has a large swing amplitude, thereby providing a food processing appliance that can weaken the transmission of motor vibration and reduce the motor shaft swing amplitude.

[0004] In order to solve the above technical problems, the present invention provides a food processing device, comprising:

[0012] Optionally, a motor cantilever is provided on one side of the motor close to the motor shaft, the motor cantilever is formed by radially extending from the outer surface of the motor, and the motor cantilever is suitable for abutting against the shock absorbing spring;

[0013] A through hole is formed through the motor cantilever, the through hole is coaxially arranged with the suspension column, and the suspension column is suitable for passing through the through hole.

[0014] Optionally, the buffer assembly further comprises: a limiting bolt adapted to pass through the through hole and be fixedly connected to the suspension column; along the axial direction of the through hole (112), the bolt head of the limiting bolt and the shock absorbing spring respectively abut against the opposite side surfaces of the motor cantilever.

[0015] Optionally, the buffer assembly also includes: a buffer washer made of a soft material, the buffer washer is arranged on the upper and lower sides of the motor cantilever along the axial direction and is arranged around the through hole; the bolt head of the limiting bolt and the shock-absorbing spring are suitable for respectively abutting against the buffer washer.

[0016] Optionally, at least two of the via holes are formed through the motor cantilever, and each of the via holes is arranged corresponding to a group of the buffer components.

[0020] Optionally, the base further includes: sound-absorbing cotton, which is made of sound-absorbing material and is arranged around the outer circumference of the motor.

[0021] The technical solution of the present invention has the following advantages:

[0022] 1. The food processing device provided by the present invention has a buffer component disposed between the motor and the base, and the side of the motor away from the motor shaft is suspended in the accommodating cavity, thereby ensuring that the motor is connected to the base only through the buffer component and there is no other fixed position, thereby preventing the motor from transmitting vibration to the base through the contact part during operation, and reserving a clearance space for the movement of the motor along the axial direction, thereby being able to slow down the radial and / or axial vibration of the motor, reduce the transmission of the motor vibration to the outside, reduce the noise of the whole machine, and improve the user experience.

[0042] Embodiment 1

[0043] Combined with Figures 1 - 3 As shown, the food processing appliance provided in this embodiment includes:

[0044] Base 10, at least part of the base 10 is recessed to form a receiving cavity 16;

[0045] Motor 11, with a motor shaft protruding from one end, and at least part of the side of the motor 11 away from the motor shaft is disposed in the receiving cavity 16;

[0046] Buffer assembly 50, one end is fixedly connected to the base 10, and the other end is fixedly connected to the side of the motor 11 close to the motor shaft. The buffer assembly 50 is adapted to slow down the vibration of the motor 11 in the radial and / or axial directions;

[0047] The side of the motor 11 away from the motor shaft is suspended in the receiving cavity 16.

[0048] The receiving cavity 16 can form a clearance space for the motor 11, facilitating the placement of the motor 11 in the base 10.

[0049] Preferably, the buffer assembly 50 can be made of a soft material or an elastic material. By fixedly connecting one end of the buffer assembly 50 to the base 10 and the other end to the motor 11, when the motor 11 is running, the vibration of the motor 11 relative to the base 10 in the radial and / or axial directions can be slowed down, thereby reducing the shaking amplitude of the base 10.

[0050] It should be noted that the radial direction refers to the radial direction of the motor shaft of the motor, and the axial direction refers to the axial direction of the motor shaft of the motor.

[0051] In the food processing appliance provided in this embodiment, by providing the buffer assembly 50 between the motor 11 and the base 10, and the side of the motor 11 away from the motor shaft is suspended in the receiving cavity 16, it is ensured that the motor 11 is only connected to the base 10 through the buffer assembly 50, there is no other fixed position, and a clearance space is reserved for the movement of the motor 11 in the axial direction, avoiding the vibration being transmitted from the contact part to the base 10 when the motor 11 is running. Thus, the vibration of the motor 11 in the radial and / or axial directions can be slowed down, reducing the transmission of the motor's vibration to the outside, reducing the noise of the whole machine, and improving the user experience.

[0052] In the food processing appliance provided in this embodiment, the buffer assembly 50 is fixedly connected to the side of the motor 11 close to the motor shaft, so that the fixed position of the motor 11 is closer to the motor shaft, shortening the length of the motor shaft from the fixed position, and ensuring that the shaking amplitude of the motor shaft is limited during rotation.

[0053] By reasonably setting the fixed position of the buffer component 50 and the motor 11, the fixed position of the motor 11 is made closer to the motor shaft, that is, the shaking amplitude at one end close to the motor shaft is restricted, and at the same time, the other end far from the motor shaft is in a suspended state and has no direct contact with the base 10, so that the vibration cannot be directly transmitted to the outside, thereby reducing the noise of the whole machine.

[0054] Specifically, the buffer component 50 includes:

[0055] A damping spring 52, one end of which abuts against the base 10 and the other end abuts against the motor 11;

[0056] A suspension column 51 is arranged on the base 10, and the damping spring 52 is sleeved on the outer peripheral side of the suspension column 51.

[0057] By using the damping spring 52 to connect the base 10 and the motor 11, the rigid connection between the motor 11 and the base 10 is avoided, the damping effect is effectively improved, and the base 10 is prevented from vibrating following the motor 11.

[0058] By setting the suspension column 51 and sleeving the damping spring 52 on the outer peripheral side of the suspension column 51, the movement of the damping spring 52 can be limited and guided, and the shaking amplitude of the damping spring 52 in the radial direction can be restricted.

[0059] Specifically, a motor cantilever 111 is arranged on one side of the motor 11 close to the motor shaft. The motor cantilever 111 extends radially from the outer surface of the motor 11, and the motor cantilever 111 is adapted to abut against the damping spring 52;

[0060] A through hole 112 is formed through the motor cantilever 111. The through hole 112 is coaxially arranged with the suspension column 51, and the suspension column 51 is adapted to pass through the through hole 112.

[0061] Preferably, the motor cantilever 111 extends radially from the outer surface of the motor 11. Specifically, the motor cantilever 111 can be an eaves-shaped structure extending radially from the outer surface of the motor 11. A through hole 112 is formed through the motor cantilever 111. The through hole 112 can provide a clearance for the suspension column 51. When the motor 11 expands and contracts in the axial direction, the damping spring 52 is compressed, and the suspension column 51 can extend into the through hole 112, thereby avoiding interference between the motor cantilever 111 and the suspension column 51.

[0062] Specifically, in combination with Figure 2As shown, the buffer assembly 50 further includes: a limit bolt 54, which is adapted to pass through the through hole 112 and be fixedly connected to the suspension column 51; along the axial direction of the through hole (112), the bolt head of the limit bolt 54 and the shock-absorbing spring 52 respectively abut against the opposite side surfaces of the motor cantilever 111.

[0063] Preferably, in this embodiment, the bolt head of the limit bolt 54 abuts against the upper surface of the motor cantilever 111, and the shock-absorbing spring 52 abuts against the lower surface of the motor cantilever 111, so as to limit the maximum height of the motor 11. At the same time, when the motor 11 is subjected to a downward pressure or vibrates, the shock-absorbing spring 52 can be compressed, causing the motor 11 to move downward to ensure a certain buffer displacement.

[0064] Specifically, the buffer assembly 50 further includes: a buffer washer 53, which is made of a soft material. The buffer washer 53 is disposed on the upper and lower sides of the motor cantilever 111 along the axial direction and surrounds the through hole 112; the bolt head of the limit bolt 54 and the shock-absorbing spring 52 are adapted to respectively abut against the buffer washer 53.

[0065] Preferably, the buffer washer is made of a soft material, with large ends and a small middle, and has a through hole along the axial direction. During assembly, because the buffer washer has elasticity, it can be squeezed and deformed and then installed into the through hole 112 of the motor cantilever 111. Then the upper and lower washers are respectively disposed on the upper and lower surfaces of the motor cantilever.

[0066] The food processing appliance provided in this embodiment can make the buffer washer 53 act as an intermediate layer to abut against the bolt head of the limit bolt 54 and the shock-absorbing spring 52 by arranging the buffer washer 53 on the upper and lower sides of the motor cantilever 111 along the axial direction, avoiding rigid connection, and thus further reducing vibration.

[0067] Specifically, at least two through holes 112 are formed through the motor cantilever 111, and each through hole 112 is correspondingly provided with a set of buffer assemblies 50.

[0068] Preferably, in this embodiment, a through hole 112 is respectively provided at the four corners of the motor cantilever 111, and four sets of buffer assemblies 50 are correspondingly provided on the base 10. Thus, when the motor 11 shakes in all directions, a buffering effect can be achieved.

[0069] Preferably, buffer washers 53 are installed in the through holes 112 at the four corners of the motor cantilever 111.

[0070] Specifically, the projected area of the motor cantilever 111 facing the accommodation cavity 16 is larger than the opening side area of the accommodation cavity 16.

[0071] By setting the projected area of the motor cantilever 111 facing the accommodation cavity 16 to be larger than the opening side area of the accommodation cavity 16, when the motor 11 is assembled with the base 10, the motor cantilever 111 plays a limiting role to prevent the motor 11 from completely falling into the accommodation cavity 16, ensuring that the part of the motor 11 extending into the accommodation cavity 16 can be in a suspended state. Specifically, a support portion 17 is further provided on the base 10, and the support portion 17 is disposed around the opening side of the accommodation cavity 16; the suspension post 51 is fixed to the support portion 17.

[0072] Combined with Figure 1 As shown, the projected area of the motor cantilever 111 facing the accommodation cavity 16 is larger than the opening side area of the accommodation cavity 16, so that the motor cantilever 111 is always located relatively above the accommodation cavity 16. And the suspension post 51 is provided on the support portion 17, so that after the motor cantilever 111 is supported by the support portion 17, a part of the motor 11 can be always located inside the accommodation cavity 16. The base 10 serves as a load-bearing member for the motor and also for the whole machine. The force is simple and reliable, with better balance and buffering, reducing vibration and making the operation smoother.

[0073] Preferably, combined with Figure 1 As shown, there is no contact between the bottom of the motor 11 and the inside of the base 10, ensuring that the motor 11 is always in a suspended state and leaving a clearance space for the movement of the motor 11 in the axial direction.

[0074] Specifically, the base 10 further includes: an air guide cover 14, which is disposed inside the accommodation cavity 16 and surrounds the outer peripheral side of the motor 11.

[0075] The air guide cover 14 can reasonably guide the air flow and reduce the noise when the motor 11 operates.

[0076] Specifically, the base 10 further includes: a sound-absorbing cotton 15, which is made of a sound-absorbing material and surrounds the outer peripheral side of the motor 11.

[0077] For the food processing appliance provided in this embodiment, by providing the air guide cover 14 and the sound-absorbing cotton 15 on the base 10 and cooperating with the buffer assembly 50, the noise when the motor 11 operates is further reduced, making the whole machine operate more smoothly and quietly.

[0078] Embodiment Two

[0079] Combined with Figures 4 - 6 As shown, the food processing appliance provided in this embodiment further includes a grinding assembly 40, and the grinding assembly 40 includes:

[0080] A static grinding disc 42;

[0081] The moving grinding disc 43 is arranged relatively above the static grinding disc 42 in the height direction, and the moving grinding disc 43 is adapted to rotate relative to the static grinding disc 42;

[0082] The moving grinding disc 43 includes: a spiral feeding groove 432, which is arranged around the outer peripheral surface of the moving grinding disc 43, and the spiral feeding groove 432 is continuously arranged from the bottom surface to the top surface of the moving grinding disc 43; a material discharging port 431, which penetrates through the top surface and the bottom surface of the moving grinding disc 43.

[0083] Preferably, in this embodiment, the static grinding disc 42 remains stationary during the grinding of the grinding assembly, and the moving grinding disc 43 rotates relative to the static grinding disc 42; as a deformation, the static grinding disc 42 and the moving grinding disc 43 can rotate in opposite directions.

[0084] Specifically, grinding surfaces are respectively arranged on the lower surface of the moving grinding disc 43 and the upper surface of the static grinding disc 42. The grinding surfaces are made of the same material as the main body of the grinding disc, and ceramics are preferably used in this embodiment. The grinding surfaces are rough and have a granular feel, which can grind food ingredients better.

[0085] The food processing appliance provided in this embodiment enables the grinding material to be lifted along the spiral feeding groove 432 to the top surface of the moving grinding disc 43 by arranging the spiral feeding groove 432 on the outer peripheral surface of the moving grinding disc 43 and penetrating the material discharging port 431 between the top surface and the bottom surface of the moving grinding disc 43. Subsequently, the grinding material falls back to the bottom surface from the material discharging port 431 on the top surface of the moving grinding disc 43. In this way, the reciprocating cycle grinding of the grinding material is realized, so that the grinding material can be fully ground, ensuring the fineness of grinding and improving the use experience.

[0086] Preferably, the grinding material can be food ingredients or medicinal materials.

[0087] The grinding surfaces of the moving grinding disc 43 and the static grinding disc 42 can grind the grinding material. When the moving grinding disc 43 rotates relative to the static grinding disc 42, the grinding of the grinding material is realized by the grinding surfaces. A spiral feeding groove 432 is also arranged on the outer peripheral surface of the moving grinding disc 43. As the moving grinding disc 43 rotates, the grinding material is lifted along the spiral feeding groove 432 to the top surface of the moving grinding disc 43. Subsequently, the grinding material falls back to the bottom surface from the material discharging port 431 on the top surface of the moving grinding disc 43 and is ground again between the grinding surfaces of the moving grinding disc 43 and the static grinding disc 42. In this way, the repeated grinding of the grinding material is realized.

[0088] In one implementation form, the spiral feeding groove 432 has a certain depth, and the grinding material can be lifted by its own groove.

[0089] In some other implementation forms, the spiral lifting chute 432 is relatively shallow and is arranged with a clearance from the filter screen cylinder. Relying on the restraint and guidance of the filter screen cylinder, the grinding material can be lifted following the spiral lifting chute 432.

[0090] Specifically, the spiral lifting chute 432 gradually rises in the direction opposite to the rotation direction of the moving grinding disc 43.

[0091] For the food processing appliance provided in this embodiment, by arranging the spiral lifting chute 432 to gradually rise in the direction opposite to the rotation direction of the moving grinding disc 43, during the rotation of the moving grinding disc 43, the grinding material can be lifted along the spiral lifting chute 432 by means of the rotational force, without the need to additionally arrange a feeding mechanism, rationally utilizing the rotation of the moving grinding disc 43 itself, improving the structural utilization rate, and reducing the number of components.

[0092] Specifically, the moving grinding disc 43 further includes a guiding inclined surface 433, which gradually inclines from the edge area of the top surface of the moving grinding disc 43 towards the feeding port 431 and is adapted to guide the grinding material to converge towards the feeding port 431.

[0093] Preferably, by arranging the guiding inclined surface 433 on the moving grinding disc 43, the top surface of the moving grinding disc is configured as a concave surface, and the feeding port 431 is arranged at the lowest point of the concave surface, so as to guide the grinding material on the top surface of the moving grinding disc 43 to converge towards the feeding port 431.

[0094] Preferably, the feeding port 431 is located at a position of the moving grinding disc 43 close to the rotation axis, so that the grinding material falling from the feeding port 431 can fall on the grinding center area between the moving grinding disc 43 and the static grinding disc 42, thereby increasing the grinding distance, prolonging the grinding time for each grinding, and improving the grinding efficiency.

[0095] Specifically, a plurality of guiding grooves 421 are arranged on the grinding surface of the static grinding disc 42. The guiding grooves 421 extend from the center of the static grinding disc 42 towards the circumferential edge, and the bending direction of the guiding grooves 421 is the same as the rotation direction of the moving grinding disc 43.

[0096] For the food processing appliance provided in this embodiment, by arranging a plurality of guiding grooves 421 on the grinding surface and the bending direction of the guiding grooves 421 being the same as the rotation direction of the moving grinding disc 43, it is convenient for the grinding material to move from the center of the static grinding disc 42 towards the circumferential edge under the guidance of the guiding grooves 421, and further convenient for the spiral lifting chute 432 on the outer circumferential surface of the moving grinding disc 43 to lift the grinding material, improving the circulation efficiency, avoiding the accumulation of some grinding material between the moving grinding disc 43 and the static grinding disc 42, and enabling all the grinding material to have the opportunity to be ground.

[0097] Preferably, a grinding surface is also provided on the bottom surface of the moving grinding disc 43. A plurality of guiding grooves 421 are also provided on the grinding surface of the moving grinding disc 43. The guiding grooves 421 of the moving grinding disc 43 extend from the center of the moving grinding disc 43 towards the circumferential edge, and the bending direction of the guiding grooves 421 is opposite to the rotating direction of the moving grinding disc 43, so as to facilitate pushing the grinding material towards the circumferential edge of the moving grinding disc 43.

[0098] Taking the grinding material as food ingredients as an example, when the grinding assembly is specifically used, after the food ingredients are soaked and heated to soften, first all the food ingredients are put on the top of the moving grinding disc 43. As the moving grinding disc rotates, the food ingredients gradually fall between the grinding surfaces of the moving grinding disc 43 and the static grinding disc 42 from the feeding port 431 of the moving grinding disc 43. The moving grinding disc assembly rotates to grind the food ingredients. Under the guidance of the guiding grooves 421 on the grinding surface, the food ingredients after primary grinding will gradually converge at the circumferential edge of the moving grinding disc 43, and then under the pushing of the spiral lifting groove 432, the food ingredients are transferred to the top surface of the moving grinding disc and enter the feeding port 431 again, forming a circulating grinding process.

[0099] Preferably, the food ingredients are ground in a water environment, such as grinding soybeans swollen with water.

[0100] Specifically, the grinding assembly further includes:

[0101] A filter screen cylinder 41, which is arranged around the outer peripheral side of the moving grinding disc 43, and the filter screen cylinder 41 is fixedly connected with the static grinding disc 42;

[0102] A plurality of filter holes 411 are provided on the wall surface of the filter screen cylinder 41.

[0103] Preferably, the filter screen cylinder 41 is configured as a cylindrical structure. The moving grinding disc 43 is arranged inside the filter screen cylinder 41, and a gap is provided between the outer peripheral surface of the moving grinding disc 43 and the filter screen cylinder 41.

[0104] In the food processing appliance provided in this embodiment, by arranging the filter screen cylinder 41 on the outer peripheral side of the moving grinding disc 43, on the one hand, when the moving grinding disc 43 rotates, the filter screen cylinder 41 can provide lateral support for the grinding material to prevent it from slipping. On the other hand, a plurality of filter holes 411 are provided on the wall surface of the filter screen cylinder 41, so that after the grinding material is ground, the grinding material with a fine enough particle size can be discharged from the filter holes 411, and the coarse-grained grinding material continues to be ground in a cycle.

[0105] Preferably, a plurality of filter holes 411 are provided at the position of the filter screen cylinder 41 corresponding to the moving grinding disc 43, so that when the grinding material is lifted along the spiral lifting groove 432, the grinding material with a fine enough particle size can be screened, increasing the contact time between the grinding material and the filter screen cylinder 41, facilitating screening the grinding material at any time as the moving grinding disc 43 rotates, and improving the screening efficiency.

[0106] Preferably, the diameter of the filtering holes 411 in the upper relative position of the filter cartridge 41 in the height direction is larger than that of the filtering holes 411 in the lower relative position. Since there is a mating relationship between the lower part of the filter cartridge 41 and the moving grinding disc 43, the ground material after grinding will be transferred from the spiral lifting groove 432 on the outer peripheral surface of the moving grinding disc to the top. During this process, the ground material contacts the lower part of the filter cartridge and is subjected to a certain extrusion force. Therefore, the diameter of the filtering holes 411 here is smaller, and the large particles of unground food materials are not easily filtered out. The upper region of the filter cartridge 41 does not contact the moving grinding disc 43 and there is no extrusion force. Therefore, the diameter of the filtering holes 411 in the upper region of the filter cartridge 41 is larger, which facilitates the natural discharge of the ground material that meets the conditions.

[0107] Preferably, a clamping buckle 413 is provided at the lower edge of the filter cartridge 41 in the axial direction. Correspondingly, a clamping groove 422 is provided on the static grinding disc 42. The clamping buckle 413 and the clamping groove 422 are fastened and fixed together, thereby realizing the fixed connection between the filter cartridge 41 and the static grinding disc 42.

[0108] Preferably, the food processing appliance provided in this embodiment further includes:

[0109] A cup body assembly 20;

[0110] And a grinding assembly 40 as described above disposed in the cup body assembly 20.

[0111] By arranging the grinding assembly 40 in the cup body assembly 20, the food processing appliance provided in this embodiment enables the ground material to be sufficiently ground by means of the cyclic grinding of the grinding assembly 40, ensures the fineness of grinding, and discharges the ground material that meets the requirements into the cup body assembly 20, facilitating subsequent cooking, boiling and other operations, without the need to repeatedly replace the appliance, and improving the user experience.

[0112] Specifically, the cup body assembly 20 includes a rotating shaft 22. One end of the rotating shaft 22 is connected to the driving unit, and the other end passes through the static grinding disc 42 and is fixedly connected to the moving grinding disc 43.

[0113] Preferably, a rotating shaft hole 423 is formed through the central axis position of the static grinding disc 42. The rotating shaft 22 passes through the rotating shaft hole 423 of the static grinding disc 42, and the rotating shaft 22 can rotate freely relative to the static grinding disc 42. Preferably, the static grinding disc 42 and the rotating shaft 22 are connected and matched through a bearing.

[0114] Preferably, the rotating shaft 22 passes through the central axis of the moving grinding disc 43, and the rotating shaft 22 is fixedly connected to the moving grinding disc 43, so as to drive the moving grinding disc 43 to rotate under the drive of the rotating shaft 22, realizing grinding.

[0115] Specifically, the cup assembly 20 further includes:

[0116] A cup wall 24, which is spaced apart from the filter screen cylinder 41 of the grinding assembly;

[0117] A heating plate 21, which is arranged at a position relatively below the grinding assembly in the height direction, and the heating plate 21 and the cup wall 24 enclose a receiving cavity;

[0118] A blade 23, which is sleeved on the rotating shaft 22, and the blade 23 is arranged at a position relatively below the grinding assembly and is adapted to stir the food materials in the receiving cavity.

[0119] Preferably, the receiving cavity is used to receive food materials such as ground materials and water.

[0120] Preferably, after the ground materials are repeatedly ground in the grinding assembly, the ground materials that are sufficiently ground and reach a sufficiently fine particle size pass through the filter holes 411 of the filter screen cylinder and enter the cup assembly 20, and are heated in the cup assembly, while the coarse-grained ground materials continue to be circulated and ground.

[0121] Preferably, a sealing member is arranged at the contact part between the heating plate 21 and the cup wall 24, so as to ensure the sealing performance of the receiving cavity.

[0122] For the food processing appliance provided in this embodiment, the blade 23 is sleeved on the rotating shaft 22, so that by using one rotating shaft 22, the dynamic grinding disc 43 is driven to rotate, and at the same time, the blade 23 is also driven to rotate, thereby improving the utilization rate, eliminating the need to set up a dual motor, reducing costs and saving energy consumption.

[0123] Since the filter screen cylinder 41 is fixedly connected to the static grinding disc 42, and the static grinding disc 42 is only sleeved and connected to the rotating shaft 22, when the dynamic grinding disc 43 rotates, the whole formed by the filter screen cylinder 41 and the static grinding disc 42 is prone to shaking. Preferably, a flanging stop 412 is further arranged at the upper edge of the filter screen cylinder 41 along the axial direction, and the flanging stop 412 can be clamped with the cup cover 30, so as to limit the filter screen cylinder 41 through the cup cover 30, reduce the shaking of the filter screen cylinder 41, ensure the structural stability and reduce the noise.

[0124] Preferably, the cup assembly 20 is arranged on the upper part of the base 10, and the cup assembly can be conveniently separated from the base.

[0125] Preferably, the drive unit includes a motor 11 and a coupler. The coupler is adapted to connect the output shaft of the motor 11 to the rotating shaft 22, so as to disconnect when the cup body assembly is separated from the base assembly, and ensure the connection between the motor 11 and the rotating shaft 22 when the cup body assembly and the base assembly are assembled together.

[0126] Specifically, the food processing appliance further includes: a cup lid 30, which is adapted to be detachably connected to the opening of the cup body assembly 20. The opening of the cup body assembly 20 facilitates the feeding of the grinding material and the pouring out of the processed food materials. At the same time, the opening of the cup body assembly 20 also facilitates the disassembly and installation of the grinding assembly, thereby facilitating cleaning.

[0127] Preferably, the cup lid 30 can be firmly connected to the cup body assembly 20 by a rotary buckle.

[0128] Preferably, a steam valve is further provided on the cup lid 30.

[0129] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
