The first rotating shaft 302 of the first rotor assembly 30 and the second rotating shaft 402 of the second rotor assembly 40 are directly connected with the cutter assembly 70 located in the cup 202, and then the first rotor assembly 30 and the second rotor assembly 40 are used for directly driving the cutter assembly 70 to rotate, so that the advantages of low running noise and small vibration are achieved, and although the scheme that the cutter assembly 70 is directly connected with the first rotating shaft 302 and the second rotating shaft 402 is excellent in effect, the cutter assembly 70 is not connected with the first rotating shaft 302 and the second rotating shaft 402 through other devices. Compared with the assembly structure in the related art, the first rotor assembly 30 and the second rotor assembly 40 directly drive the cutter assembly 70 to rotate, compared with the scheme that the motor is indirectly connected with the cutter assembly 70 through two magnetic disks or a coupler in the related art, the height of the whole machine can be reduced, and the bad experience that the base 10 and the cup body assembly 20 are not easy to take due to the fact that magnetic force between the two magnetic disks adsorbs in the related art is overcome. Preferably, the cutter assembly 70 includes a first cutter disposed on the first spindle 302 and a second cutter disposed on the second spindle 402.

As shown in fig. 5, the food processing device 1 according to the embodiment of the present invention includes: the base 10, the cup assembly 20 and the cutter assembly 70, the cup assembly 20 includes a cup 202, and the first rotating shaft 302 and the second rotating shaft 402 extend from the side wall of the cup 202 into the cup 202.

Optionally, the first and second rotor assemblies 30 and 40 are distributed in a horizontal direction, and the first rotor assembly 30 is located on a side of the second rotor assembly 40 adjacent to the cup 202.

In this embodiment, the first rotating shaft 302 and the second rotating shaft 402 are set to extend into the cup body 202 from the side wall of the cup body 202, so that the blades of the knife assembly 70 on the first rotating shaft 302 and the second rotating shaft 402 can be in a substantially vertical state or an inclined state, and therefore, during the rotation of the knife assembly 70, no matter the food material is cut vertically or obliquely, a left-right push-pull force is generated on the food material, so that the food material flows in the left-right direction, and due to the limitation of the spatial structure of the cup body 202, the food material collides with the side wall of the cup body 202, and a restriction force is given to the food material by the side wall of the cup body 202 to restrict the stroke of the food material, so that the food material cannot form a cavity in the horizontal direction, and the phenomenon that the blade of the knife assembly 70 in the related art is in a horizontal state and a cavity is formed above the blade in the horizontal state, the working noise of the food processing device is reduced. Moreover, by making the blades of the cutter assembly 70 in a substantially vertical state or in an inclined state, the cleaning of the cutter assembly 70 is greatly facilitated, and the direct washing of the cutter assembly 70 with water is facilitated, compared to the related art in which the blades of the cutter assembly 70 are in a horizontal state and the back surfaces of the blades of the cutter assembly 70 cannot be directly washed with water.

Alternatively, in the case that the first rotating shaft 302 and the second rotating shaft 402 extend into the cup 202 from the side wall of the cup 202, the first rotating assembly 30 and the second rotating assembly 40 are distributed along the horizontal direction, the first rotating assembly 30 is located at one side of the second rotating assembly 40 close to the cup 202, the second rotating shaft 402 extends into the cup 202 through the first rotating shaft 302, and the second rotating shaft 402 is located above the first rotating shaft 302, so that the cutter assemblies 70 located on the first rotating shaft 302 are spaced apart from the cutter assemblies 70 located on the second rotating shaft 402, and a crushing area is formed between the two cutter assemblies 70, so that the food material to be crushed is sufficiently crushed in the crushing area for multiple times, and the crushing efficiency and the crushing effect are further improved.

It should be noted that the tool assembly 70 may be configured to be detachably connected to the spindle, so as to facilitate replacement of the tool assembly 70 or assembly of other components on the spindle. In addition, the sidewall of the default cup 202 is a wall surface that is circumferentially distributed when the cup assembly 20 is in an operating state.

Optionally, the inner sidewall of the cup 202 is a smooth inner sidewall.

In this embodiment, by setting the inner sidewall of the cup 202 to be a smooth inner sidewall, i.e., eliminating the need for a spoiler on the inner sidewall of the cup 202, the cup 202 can be made more lightweight and easy to clean the cup 202.

EXAMPLE five

In any of the above embodiments, as shown in fig. 1 and 2, optionally, the first rotating shaft 302 is configured as a hollow structure with a through hole, and the second rotating shaft 402 extends out of the first rotating shaft 302 from the through hole.

In this embodiment, by disposing the first rotating shaft 302 as a hollow structure having a through hole and disposing the second rotating shaft 402 in the through hole of the first rotating shaft 302 and extending out of the first rotating shaft 302, structural interference between the first rotating shaft 302 and the second rotating shaft 402 can be avoided, so as to ensure smooth operation of the first rotating shaft 302 and the second rotating shaft 402.

Optionally, the distance between the inner wall of the first rotating shaft 302 and the outer wall of the second rotating shaft 402 may be set to be between 0.5mm and 2mm, so as to further ensure smooth operation of the first rotating shaft 302 and the second rotating shaft 402, and ensure sufficient thickness and strength of the first rotating shaft 302 and the second rotating shaft 402, thereby ensuring the service life of the product. It is understood that the second shaft 402 may be a hollow structure or a solid structure.

EXAMPLE six

In any of the above embodiments, as shown in fig. 1-5, preferably, the stator assembly has mating surfaces that mate with the first and second rotor assemblies 30, 40, the mating surfaces being disposed opposite a portion of the outer peripheral surface of the first rotor assembly 30 and a portion of the outer peripheral surface of the second rotor assembly 40 to enable the first and second rotor assemblies 30, 40 to be separated from the stator assembly in the radial and/or axial directions thereof.

In this embodiment, the surfaces of the stator assembly that mate with the first and second rotor assemblies 30 and 40 are mating surfaces that surround portions of the outer circumferential surfaces of the first and second rotor assemblies 30 and 40, i.e., the stator assembly does not completely surround the first rotor assembly 30, so that the first and second rotor assemblies 30 and 40 can be separated from the first stator group in the radial direction thereof. Of course, it will be appreciated that the first and second rotor assemblies 30, 40 may also be separated from the stator assembly in the axial direction. Specifically, the mating surfaces surround portions of the outer peripheral surfaces of the first and second rotor assemblies 30 and 40, i.e., the rotor assemblies are non-closed structures, thereby enabling the first and second rotor assemblies 30 and 40 to disengage from the stator assembly.

Specifically, the faces of the stator assembly corresponding to the end faces of the stator teeth 64 constitute mating faces of the stator assembly.

It can be understood that compare in the stator module among the correlation technique, set up stator module into non-confined structure for stator module's weight becomes light, and then has realized the lightweight of whole product, and convenience of customers draws the use, and occupation space diminishes, also is convenient for accomodating of food processing apparatus 1.

As shown in fig. 1 and 3 to 5, a food processing device 1 according to an embodiment of the present invention includes: the base 10 comprises a cup body assembly mounting area 102, and the cup body assembly 20 comprises a cover body 204, a rotor mounting area and an avoiding notch 206.

Specifically, the cup assembly mounting area 102 is configured to accommodate the removable placement of the cup assembly 20 onto the base 10, with the stator assembly being located on one side of the cup assembly mounting area 102; the rotor mounting area is arranged on the cover 204, the first rotor assembly 30 and the second rotor assembly 40 are rotatably arranged in the rotor mounting area, and the projection of the first rotor assembly 30 and the second rotor assembly 40 on the cover 204 constitutes the rotor mounting area; an avoidance gap 206 is provided on the cage 204, and when the cup assembly 20 is placed on the base 10, the stator assembly extends into the cage 204 through the avoidance gap 206.

In this embodiment, by providing the cup assembly mounting region 102 on the base 10, the stator assembly is located on one side of the cup assembly mounting region 102, so as to define the setting position of the stator assembly relative to the cup assembly 20 after the base 10 and the cup assembly 20 are assembled, thereby providing effective structural support for the subsequent stator assembly to drive the rotor assembly to rotate; further, providing the rotor mounting area on the cover 204, i.e., indirectly defining the rotation area of the first and second rotor assemblies 30 and 40, provides a reliable and sufficient rotation space for the rotation of the first and second rotor assemblies 30 and 40, thereby ensuring the stability, safety and reliability of the operation of the first and second rotor assemblies 30 and 40.

Further, by providing an avoiding gap 206 on the cover 204, when the cup assembly 20 is placed on the base 10, the stator assembly passes through the avoiding gap 206 and extends into the cover 204, so that the stator assembly reaches the matching area with the first rotor assembly 30 and the second rotor assembly 40, and the avoiding gap 206 provides effective structural support for the matching of the stator assembly with the first rotor assembly 30 and the second rotor assembly 40.

Optionally, the clearance gap 206 is located outside of the rotor mounting area, and when the cup assembly 20 is placed on the base 10, the stator assembly passes through the clearance gap 206 and is located outside of the first and second rotor assemblies 30, 40. Through the reasonable setting of the position of the avoiding gap 206, the avoiding gap 206 is located outside the rotor installation area, and thus, when the cup body assembly 20 is assembled with the base 10, the stator assembly passes through the avoiding gap 206 and is located outside the first rotor assembly 30 and the second rotor assembly 40, that is, the avoiding gap 206 defines the assembly position of the stator assembly relative to the first rotor assembly 30 and the second rotor assembly 40, that is, the avoiding gap 206 defines the moving path of the stator assembly in the cup body assembly 20, and reliable and safe structural guarantee is provided for the stator assembly to drive the first rotor assembly 30 and the second rotor assembly 40 to rotate.

EXAMPLE seven

As shown in fig. 1-5, in any of the above embodiments, optionally, the stator assembly includes a first stator group 50 and a second stator group 60; the first stator set 50 is configured to be able to drive the first rotor assembly 30 to rotate; the second stator group 60 is configured to drive the second rotor assembly 40 to rotate.

In this embodiment, the stator assembly includes a first stator group 50 and a second stator group 60, wherein the first stator group 50 can drive the first rotor assembly 30 to rotate, the second stator group 60 can drive the second rotor assembly 40 to rotate, the first rotor assembly 30 and the second rotor assembly 40 are respectively and independently driven to rotate by the first stator group 50 and the second stator group 60, so that the first rotor assembly 30 and the second rotor assembly 40 can move in different rotating speeds and rotating directions to form turbulent flow, and the working states of the two cutter assemblies 70 can be adjusted according to actual requirements, thereby improving the crushing effect and the crushing efficiency of the food processing device 1, and improving the quality and the taste of food materials.

It is understood that the first stator set 50 is preferably disposed at one side of the first rotor assembly 30, which facilitates the first stator set 50 to drive the first rotor assembly 30 to rotate, i.e., in the case that the first rotor assembly 30 and the second rotor assembly 40 are distributed in the vertical direction, and the first rotor assembly 30 is located above the second rotor assembly 40, and accordingly, the first stator set 50 and the second stator set 60 are also distributed in the vertical direction, and the first stator set 50 is located above the second stator set 60; or in the case where the first and second rotor assemblies 30 and 40 are distributed in the horizontal direction, and the first rotor assembly 30 is located at a side of the second rotor assembly 40 adjacent to the cup 202, the first and second stator groups 50 and 60 are also distributed in the horizontal direction, and the first stator group 50 is located at a side of the second stator group 60 adjacent to the cup assembly 20.

Alternatively, the surface of the first stator assembly 50 that mates with the first rotor assembly 30 is a mating surface that is disposed opposite a portion of the outer circumferential surface of the first rotor assembly 30, i.e., the first stator assembly 50 does not completely surround the first rotor assembly 30, such that the first rotor assembly 30 can be separated from the first stator assembly 50 in the radial direction thereof. Of course, it will be appreciated that the first rotor assembly 30 may also be separated from the first stator set 50 in the axial direction. Specifically, since the mating surface is disposed opposite to a portion of the outer peripheral surface of the first rotor assembly 30, that is, the first stator assembly 50 is a non-closed structure, the first rotor assembly 30 can be detached from the first stator assembly 50. It will be appreciated that the same cooperation between the second stator group 60 and the second rotor assembly 40 as between the first stator group 50 and the second rotor assembly 40 also achieves that the second rotor assembly 40 can be separated from the second stator group 60 in the radial and/or axial direction thereof, and will not be described again here.

Optionally, the first stator group 50 includes at least one stator, the second stator group 60 includes at least one stator, based on the number of stators in the first stator group 50 and the second stator group 60 being one, the stator includes a stator core 62 and at least two stator windings 66, the stator core 62 has stator teeth 64 thereon, the at least two stator windings 66 are respectively disposed on the stator teeth 64, and the at least two stator windings 66 can generate a magnetic field when energized, so that the first rotor assembly 30 and the second rotor assembly 40 rotate under the action of the magnetic field. Based on the number of the stators in the first stator group 50 and the second stator group 60 being a plurality, each stator comprises a stator core 62 and at least one stator winding 66, the stator core 62 has stator teeth 64 thereon, the at least one stator winding 66 is disposed on the stator teeth 64, and the stator windings 66 of the plurality of stators can jointly generate a magnetic field when being energized, so that the first rotor assembly 30 and the second rotor assembly 40 rotate under the action of the magnetic field.

Specifically, the first stator group 50 and the first rotor assembly 30 are taken as an example for the following description, and the second stator group 60 and the second rotor assembly 40 are similar thereto, and a repeated description thereof is omitted:

optionally, at least two stator teeth 64 of the first stator group 50 are equally spaced circumferentially on the stator core 62. The stator core 62 is at least provided with two stator teeth 64, when more than two stator teeth 64 exist, the stator teeth 64 are distributed on the stator core 62 along the circumferential direction, the stator teeth 64 are distributed at equal intervals, the first stator group 50 partially surrounds the first rotor assembly 30, in order to enable the magnetic force generated by the magnetic field generated by each stator core 62 to the first rotor assembly 30 to be the same, the stator teeth 64 are arranged at equal intervals along the circumferential direction, the first rotor assembly 30 rotates under the action of uniform magnetic force, the vibration generated by the first rotor assembly 30 in the rotating process is reduced, the noise generated by the motor in the working process is reduced, and the service life of the motor is prolonged.

Optionally, the end surfaces of the at least two stator teeth 64 near the first rotor assembly 30 are all equidistant from the center of rotation of the first rotor assembly 30, ensuring that the magnetic field generated by each stator winding 66 is equal to the magnetic force generated by the first rotor assembly 30.

Optionally, the number of the stator teeth 64 is two, and the stator windings 66 on the two stator teeth 64 are sequentially energized and have the same polarity; or the number of the stator teeth 64 is two, the stator windings 66 on the two stator teeth 64 are energized simultaneously and have different polarities, and the magnetic poles of the stator windings 66 on the two stator teeth 64 alternate.

Specifically, when two stator teeth 64 are arranged in the stator assembly, there are two schemes for driving the first rotor assembly 30, wherein one scheme is that the stator windings 66 on the two stator teeth 64 are sequentially electrified, and the polarities generated by the two stator windings 66 when electrified are the same, according to the principle of magnetic attraction, the magnetic force generated by the stator windings 66 acts on the first rotor assembly 30 to rotate, and the two stator windings 66 are sequentially electrified, so that the two stator windings 66 sequentially generate acting force on the first rotor assembly 30, thereby driving the first rotor assembly 30 to rotate continuously; the other is that the stator windings 66 on the two stator teeth 64 are energized simultaneously, the two stator windings 66 generate different polarities when energized, the magnetic force generated by the stator windings 66 acts on the first rotor assembly 30 to rotate the first rotor assembly, and during the process of controlling the rotation of the first rotor assembly 30 by energizing, the polarities of the two stator windings 66 are alternately changed, so that the two stator windings 66 sequentially generate magnetic forces with different polarities, that is, the two stator windings 66 sequentially generate acting forces on different magnetic poles on the first rotor assembly 30, thereby driving the first rotor assembly 30 to rotate continuously.

It can be understood that two setting schemes of the stator winding 66 can be selected according to actual conditions and working requirements when the stator assembly is set, so that the flexibility of the stator assembly setting of the motor is further enhanced, and the applicability of the motor is improved.

Wherein, the first driving scheme takes the energization polarity of the stator winding 66 as an example of N: specifically, when the stator windings 66 on the two stator teeth 64 are sequentially energized and both of them are N-poles, the first stator winding 66 is first energized to generate an N-pole magnetic field, according to the principle that the magnetic poles attract each other in opposite directions, the S-pole of the magnetic member 32 in the first rotor assembly 30 is attracted to the position of the first stator winding 66, the N-pole of the magnetic member 32 passes through the second stator winding 66, the second stator winding 66 is closer to the N-pole of the magnetic member 32 in the first rotor assembly 30, the first stator winding 66 is de-energized and the second stator winding 66 is energized simultaneously, the second stator winding 66 generates an N-pole magnetic field, and according to the principle that like poles repel each other, the N-pole magnetic field generated by the second stator winding 66 pushes the N-pole of the magnetic member 32 to move continuously toward the first stator winding 66, at this time, the second stator winding 66 is de-energized, the first stator winding 66 is energized, so that the first stator winding 66 generates an N-pole magnetic field to push the N pole of the adjacent magnetic member 32 to move continuously, and the second stator winding 66 is energized, so that the first rotor assembly 30 rotates continuously.

Wherein, the second driving scheme is that the stator windings 66 on the two stator teeth 64 are energized simultaneously and have different polarities, and the magnetic poles of the stator windings 66 on the two stator teeth 64 are alternated. The following are specific illustrations: specifically, when the first stator winding 66 is energized for the first time, the first stator winding 66 generates an N-pole magnetic field, the second stator winding 66 generates an S-pole magnetic field, and the two stator windings 66 are energized simultaneously, the first stator winding 66 emits an N-pole magnetic field, according to the principle that the magnetic poles attract each other, the first stator winding 66 attracts the S-pole of the magnetic member 32 of the first rotor assembly 30, the second stator winding 66 attracts the N-pole of the magnetic member 32 of the first rotor assembly 30, a tangential acting force is formed on the first rotor assembly 30, the magnetic poles of the first stator winding 66 and the second stator winding 66 are switched, the first stator winding 66 generates an S-pole magnetic field, the second stator winding 66 generates an N-pole magnetic field, according to the principle that the magnetic poles repel each other, the first stator winding 66 and the second stator winding 66 generate repulsive forces respectively on the S-pole of the magnetic member 32 and the N-pole of the magnetic member 32, the first rotor assembly 30 is rotated further, and the magnetic poles of the first stator winding 66 and the second stator winding 66 are switched, so that the first rotor assembly 30 is rotated continuously.

Example eight

As shown in fig. 6 to 10, in any of the above embodiments, optionally, the number of the stator teeth 64 is greater than or equal to 3, and the polarities of the stator windings 66 on any two adjacent stator teeth 64 are different.

Specifically, the first stator group 50 and the first rotor assembly 30 are taken as an example for the following description, and the second stator group 60 and the second rotor assembly 40 are similar thereto, and a repeated description thereof is omitted: when the number of the stator teeth 64 is greater than or equal to 3, it is preferable to energize two adjacent stator windings 66 together and make the polarities of the two windings opposite, so that the first rotor assembly 30 is subjected to a tangential force to power the rotation of the first rotor assembly 30. Specifically, when the number of the stator teeth 64 is set to three, the first stator winding 66 and the second stator group 60 are energized, the first stator winding 66 generates an N-pole magnetic field to attract the S-pole of the magnetic member 32 in the rotor, the second stator winding 66 generates an S-pole magnetic field to attract the N-pole of the magnetic member 32 in the rotor, a tangential acting force is formed on the rotor, then, the second stator winding 66 and the third stator winding 66 are energized, the second stator winding 66 generates an N-pole magnetic field to repel the N-pole of the magnetic member 32 in the rotor, the third stator winding 66 generates an S-pole magnetic field to repel the S-pole of the magnetic member 32 in the rotor, the rotor continues to rotate, and the rotor continues to rotate in this cycle.

Alternatively, the first and second rotor assemblies 30 and 40 include the rotating disk 34 and the magnetic members 32, respectively, and the magnetic poles of the magnetic members 32 are distributed in the circumferential direction of the rotating disk 34, thereby eliminating a rotor core structure, reducing the weight of the first and second rotor assemblies 30 and 40, and facilitating easier separation of the first and second rotor assemblies 30 and 40 from the base 10 together with the cup assembly 20.

As shown in fig. 6 to 10, in any of the above embodiments, optionally, the number of the magnetic members 32 is one, and one magnetic member 32 is annular; or the number of the magnetic members 32 is plural, and the plurality of magnetic members 32 surround to form a ring shape.

Specifically, magnetic part 32 can be a plurality of magnets along the even distribution of the circumference of carousel 34 on carousel 34, and a plurality of magnets can receive the magnetic field influence that produces after stator module circular telegram, drive carousel 34 under the effect of magnetic field force and rotate.

Specifically, magnetic member 32 may be configured as an integral ring, and is distributed along the circumferential direction of rotating disk 34, and integral magnetic member 32 also has a plurality of magnetic poles, and integral magnetic member 32 may be influenced by the magnetic field generated after stator assembly is powered on, and drives rotating disk 34 to rotate under the action of the magnetic field.

Alternatively, the number of the stator windings 66 is 3N, and the number of the magnetic poles of the magnetic member 32 is 4M; wherein N is a positive integer and M is a positive integer.

In this embodiment, the number of the stator windings 66 is defined, that is, the number of the stator windings 66 is an integer multiple of 3, and the number of the magnetic poles of the magnetic member 32 in the rotating disk 34 is an integer multiple of 4, which makes the generated magnetic field more stable, so that the stator assembly can be better matched with the first rotor assembly 30 and the second rotor assembly 40, and the output efficiency of the product is higher.

Specifically, when the requirement for the smoothness of the operation of the motor is high, the number of the stator windings 66 can be set to 6 or 9 or more, so that the number of the magnetic poles in the motor is increased, and the operation of the motor is more smooth. And each stator winding 66 is provided on the stator teeth 64, the number of stator teeth 64 should be provided the same as the number of stator windings 66.

As shown in fig. 8 to 10, the magnetic member 32 is a magnet, and the magnetic member 32 in the first and second rotor assemblies 30 and 40 is a magnet, which has the advantages of easily available materials and low production cost, and ensures that the first and second rotor assemblies 30 and 40 can continuously rotate under the influence of magnetic force in the magnetic field generated by the stator assembly.

In this embodiment, by setting the blade shapes of the plurality of cutter assemblies 70 to be completely the same or completely different or not completely the same, and setting the blade sizes of the plurality of cutter assemblies 70 to be completely the same or completely different or not completely the same, it is beneficial to fully treat the food material. Alternatively, the cutter assembly 70 with a proper shape and size can be arranged on the rotating shaft at a proper position according to requirements, and the rotating shaft at a proper position can be controlled to rotate according to requirements, while the other rotating shaft is not moved. In addition, an included angle exists between the cross sections of the blades of each cutter assembly 70 and the rotating shaft connected with the blades, namely the blades are bent and twisted for a certain angle instead of a flat sheet-shaped structure, so that the food materials can be cut or stirred fully.
