[0033] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0034] To solve the technical problems of inconvenient cleaning and easy detachment of cutting tools existing in household food processing equipment in the prior art, an embodiment of the present application provides a material processing equipment. The material processing equipment includes a cover assembly, the cover assembly has a first side and a second side, and the first side and the second side are oppositely arranged. The material processing equipment further includes a cup body, and the cup body is butted with the cover assembly at the first side to form a material holding cavity for holding materials. The cover assembly includes a cover main body, a brake sleeve and a functional member. The cover main body is provided with a first anti-rotation member, and the functional member applies a force to the brake sleeve, and the force makes the brake sleeve tend to move towards the first side; the material processing equipment further includes a cutting knife assembly, the cutting knife assembly is rotatably arranged in the cup body, the cutting knife assembly is provided with a second anti-rotation member, and the second anti-rotation member is used to cooperate with the first anti-rotation member to limit the rotation of the cutting knife assembly, and the brake sleeve is used to abut against the cutting knife assembly. The material processing equipment further includes a driving assembly, and the driving assembly is in transmission connection with the cutting knife assembly and is used to drive the cutting knife assembly to rotate. The following will be elaborated in detail.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic cross-sectional structure diagram of an embodiment of the material processing equipment of the present application, Figure 2 and which is an exploded structure diagram of an embodiment of the material processing equipment of the present application.

[0036] In one embodiment, the material processing equipment may be a household food processing equipment such as a meat grinder, a wall breaker, and a pulverizer. Of course, the material processing equipment of this embodiment can also be applied to industrial production, for example, applied to the processing and production of materials on a production line, where the materials are not limited to food ingredients, but can also be other materials that need to be processed by cutting.

[0037] The material processing equipment includes a material holding container 10, a driving assembly 20 and a cutting knife assembly 30. The material holding container 10 is provided with a material holding cavity 11. As the name implies, the material holding cavity 11 is used to hold materials, and the materials are processed in the material holding container 10. The cutting knife assembly 30 is rotatably arranged in the material holding cavity 11 and is used to cut the materials held in the material holding cavity 11. Specifically, the materials are cut by the rotation of the cutting knife assembly 30. The driving assembly 20 is used to be in transmission connection with the cutting knife assembly 30, and the driving assembly 20 is used to drive the cutting knife assembly 30 to rotate.

[0038] Specifically, the container 10 includes a lid assembly 40 and a cup body 50. The lid assembly 40 has a first side 41 and a second side 42, where the first side 41 and the second side 42 are oppositely arranged. The cup body 50 docks with the lid assembly 40 at the first side 41 to form a storage cavity 11. The cutting tool assembly 30 is rotatably arranged in the cup body 50. The cutting tool assembly 30 includes a tool bar 31, a positioning shaft 32, a cutting blade 33, and a tool shaft 34. The tool bar 31 is sleeved on the outer periphery of the positioning shaft 32, and the tool bar 31 is rotatably arranged in the cup body 50 through the positioning shaft 32. The cutting blade 33 is arranged on the outer periphery of the tool bar 31, and the cutting blade 33 is used for cutting the material. The tool shaft 34 is located at the end of the tool bar 31 away from the positioning shaft 32, and the tool shaft 34 can rotate synchronously with the tool bar 31. The driving assembly 20 has a motor as a driving member built therein, and the driving assembly 20 is used for drivingly connecting with the tool shaft 34 of the cutting tool assembly 30 to drive the tool shaft 34 to rotate, and then synchronously drive the tool bar 31 and the cutting blade 33 thereon to rotate.

[0039] The central axis of the storage cavity 11 coincides with the central axis of the cutting tool assembly 30, as Figure 1 shown by the dashed line O in the figure. That is to say, the cup body 50, the positioning shaft 32, the tool bar 31, and the tool shaft 34 are coaxially arranged. The rotation of the cutting tool assembly 30 is specifically manifested as the tool bar 31 and the tool shaft 34 rotating around the central axis to drive the cutting blade 33 on the outer periphery of the tool bar 31 to rotate.

[0040] The material processing device of this embodiment can adopt an upper-actuation form, that is, when working, the driving assembly 20 is located at the upper part of the material processing device. In this case, the driving assembly 20 is connected to the lid assembly 40 at the second side 42 of the lid assembly 40 and is drivingly connected to the cutting tool assembly 30 in the cup body 50 through the lid assembly 40, as Figure 1 shown. Of course, in other embodiments of the present application, the material processing device can also adopt a lower-actuation form, that is, when working, the driving assembly is located at the lower part of the material processing device. In this case, the driving assembly can be drivingly connected to the cutting tool assembly from the bottom of the cup body. Among them, the specific driving connection form between the driving assembly and the cutting tool assembly (i.e., the tool shaft) belongs to the understanding scope of those skilled in the art and will not be elaborated here. The following takes the material processing device adopting the upper-actuation form as an example for elaboration, only for the need of discussion and not for limitation.

[0041] Please refer to Figures 1 to 3 , Figure 3 which is a schematic cross-sectional structure diagram of an embodiment of the lid assembly and the cutting tool assembly of the present application.

[0042] In one embodiment, the lid assembly 40 includes a lid main body 43. The lid main body 43 is provided with a first anti-rotation member, and the cutting tool assembly 30 is provided with a second anti-rotation member, and the second anti-rotation member is used to cooperate with the first anti-rotation member to limit the rotation of the cutting tool assembly.

[0043] Specifically, the cover body 43 is fixedly provided with an anti-rotation sleeve 44. A first anti-rotation protrusion 441 protrudes from the inner side wall of the anti-rotation sleeve 44, that is, the first anti-rotation protrusion 441 protrudes towards the middle space of the anti-rotation sleeve 44. A second anti-rotation protrusion 311 protrudes from the outer periphery of the cutting tool assembly 30. Specifically, the second anti-rotation protrusion 311 protrudes from the outer periphery of the tool bar 31, and the second anti-rotation protrusion 311 protrudes in a direction away from the tool bar 31, as Figure 3 shown. The second anti-rotation protrusion 311 can rotate circumferentially around the cutting tool assembly 30 as the cutting tool assembly 30 rotates.

[0044] When the anti-rotation sleeve 44 is sleeved on the outer periphery of the cutting tool assembly 30, the second anti-rotation protrusion 311 can abut against the first anti-rotation protrusion 441 as the cutting tool assembly 30 rotates, so as to limit the further rotation of the cutting tool assembly 30. Therefore, the cutting tool assembly 30 can be stopped in time after the material processing is completed or when the user makes a wrong operation, reducing the risk of the cutting tool assembly 30 accidentally injuring the user. Moreover, the anti-rotation sleeve 44 is arranged on the cover assembly 40, and the anti-rotation sleeve 44 can be separated from the cutting tool assembly 30 along with the cover assembly 40, which is convenient for cleaning the anti-rotation mechanism including the first anti-rotation protrusion 441 and the second anti-rotation protrusion 311, and can reduce the residue of material debris.

[0045] After the cover assembly 40 and the cup body 50 are docked, the first anti-rotation protrusion 441 is relatively farther from the second side 42 of the cover assembly 40 than the second anti-rotation protrusion 311. This means that during the material processing after the cover assembly 40 and the cup body 50 are docked, the first anti-rotation protrusion 441 and the second anti-rotation protrusion 311 are misaligned with each other, and there is no abutting relationship between the first anti-rotation protrusion 441 and the second anti-rotation protrusion 311. At this time, the cutting tool assembly 30 can rotate normally without being restricted, so as to realize the normal material processing function of the material processing equipment. When the cover assembly 40 is lifted after the material processing is completed or when the user accidentally lifts the cover assembly 40, the first anti-rotation protrusion 441 can abut against the second anti-rotation protrusion 311 as the cover assembly 40 moves away from the cup body 50, so as to stop the cutting tool assembly 30 in time and reduce the risk of the cutting tool assembly 30 accidentally injuring the user.

[0046] Of course, in other embodiments of the present application, the first anti-rotation member and the second anti-rotation member are not limited to the forms of the above-mentioned first anti-rotation protrusion 441 and the second anti-rotation protrusion 311. For example, one of the first anti-rotation member and the second anti-rotation member may be a groove, and the other is still a protrusion, and the protrusion is kept in a state of abutting against the anti-rotation sleeve 44 or the cutting tool assembly 30 by a spring. During the material processing, the groove and the protrusion are still misaligned with each other and do not hinder the normal rotation of the cutting tool assembly 30; and after the material processing is completed or when the user accidentally lifts the cover body assembly 40, the protrusion can be embedded in the groove as the cover body assembly 40 moves away from the cup body 50, so as to stop the rotation of the cutting tool assembly 30 in time. Of course, the first anti-rotation member and the second anti-rotation member can also adopt other forms, which will not be elaborated here.

[0047] In this embodiment, the cover body assembly 40 further includes a brake sleeve 45 and a functional member. The brake sleeve 45 is used to abut against the cutting tool assembly 30, and the functional member applies a force to the brake sleeve 45, and this force makes the brake sleeve 45 tend to move towards the first side 41, so as to make the brake sleeve 45 abut against the cutting tool assembly 30.

[0048] During the process of the driving assembly 20 driving the cutting tool assembly 30 to cut the material normally, the brake sleeve 45 can abut against the cutting tool assembly 30, or the brake sleeve 45 and the cutting tool assembly 30 are spaced apart from each other in the axial direction of the cutting tool assembly 30, that is, the brake sleeve 45 does not abut against the cutting tool assembly 30. When the cutting tool assembly 30 is removed from the cup body 50 as the cover body assembly 40 moves away from the cup body 50, the cutting tool assembly 30 will abut against the brake sleeve 45, and thus the cutting tool assembly 30 is hindered from being removed from the cup body 50 under the restriction of the brake sleeve 45. The following takes the case where the brake sleeve 45 abuts against the cutting tool assembly 30 as an example for elaboration, which is only for the need of discussion and is not limited thereby.

[0049] Specifically, the functional member is an elastic member 46. The brake sleeve 45 is sleeved on the outer periphery of the anti-rotation sleeve 44, and the elastic member 46 is arranged between the brake sleeve 45 and the cover main body 43. The elastic member 46 applies an elastic restoring force to the brake sleeve 45, so that the brake sleeve 45 has a tendency to move towards the first side 41 to abut against the cutting tool assembly 30. In other words, under the action of the elastic member 46, the brake sleeve 45 can abut against the cutting tool assembly 30 that is about to be removed from the cup body 50, so that the cutting tool assembly 30 can be hindered from being removed from the cup body 50, and thus the risk of the cutting tool assembly 30 being removed from the cup body 50 is reduced.

[0050] Considering the risk that the cutting tool assembly 30 may be disengaged from the cup body 50 as the cover body assembly 40 moves away from the cup body 50, in this embodiment, during the process of the cover body assembly 40 being lifted until it is completely separated from the cup body 50, the elastic member 46 always keeps the brake sleeve 45 in contact with the cutting tool assembly 30. During this process, the cutting tool assembly 30 is always restricted from being disengaged from the cup body 50. After the cover body assembly 40 is completely separated from the cup body 50, the cutting tool assembly 30 no longer has the problem of being disengaged from the cup body 50 along with the cover body assembly 40, and thus there is no longer a need for the brake sleeve 45 to contact the cutting tool assembly 30. This embodiment can reduce the risk of the cutting tool assembly 30 being disengaged from the cup body 50, and can further reduce the risk of the cutting tool assembly 30 accidentally injuring the user. Of course, in other embodiments of the present application, the functional member can also be a magnetic member, etc. For example, a magnetic member is provided on the brake sleeve 45, and a magnetic member is also provided on the cover main body 43, and the magnetic members on the brake sleeve 45 and the cover main body 43 repel each other. The above-mentioned acting force is the repulsive force generated between the magnetic members, so that the brake sleeve 45 has a tendency to move towards the first side 41. Of course, the functional member can also adopt other forms, which will not be elaborated here.

[0051] Please continue to refer to Figure 1 and Figure 3 . In one embodiment, a first abutting portion 451 is convexly provided on the outer periphery of the brake sleeve 45, that is, the first abutting portion 451 protrudes in a direction away from the brake sleeve 45. One end of the elastic member 46 abuts against the first abutting portion 451, and the other end abuts against the cover main body 43. By compressing the elastic member 46, the elastic member 46 applies a force to the first abutting portion 451, thereby causing the brake sleeve 45 to have a tendency to move towards the first side 41.

[0052] The cover main body 43 is further provided with a fixing pressing plate 47. The fixing pressing plate 47 is located at the end of the anti-rotation sleeve 44 close to the second side 42 of the cover body assembly 40. One end of the elastic member 46 abuts against the first abutting portion 451, and the other end abuts against the fixing pressing plate 47. Further, the fixing pressing plate 47 can be locked to the cover main body 43 by fasteners such as screws.

[0053] Of course, in other embodiments of the present application, the fixing pressing plate can also be an integral structure with the cover main body, and the fixing pressing plate is integrally formed on the cover main body without being locked by fasteners.

[0054] Further, the fixing pressing plate 47 is provided with a through hole 471, and the through hole 471 communicates with the anti-rotation sleeve 44. The driving assembly 20 can be connected to the cutting tool assembly 30 through the through hole 471 on the fixing pressing plate 47 and the anti-rotation sleeve 44 in sequence.

[0055] It should be noted that the elastic member 46 can be a spring, etc., and the number of the elastic members 46 can be one or more. Figure 1 andFigure 3 The case where the number of the elastic members 46 is one is shown. The elastic member 46 is sleeved on the outer periphery of the brake sleeve 45, one end of which abuts against the first abutting portion 451 of the brake sleeve 45, and the other end abuts against the fixed pressing plate 47. Of course, in other embodiments of the present application, the elastic member 46 may not be sleeved on the brake sleeve 45, but is separately located outside the brake sleeve 45, and the elastic member 46 is clamped between the first abutting portion 451 and the fixed pressing plate 47.

[0056] Please refer to Figures 1 to 4 , Figure 4 which is a schematic structural view of an embodiment of the brake sleeve of the present application. Among them, Figure 4 the view looking at the brake sleeve 45 from the first side 41 is shown.

[0057] In one embodiment, the brake sleeve 45 includes a sleeve body 452 and a second abutting portion 453. The second abutting portion 453 is located at the end of the sleeve body 452 close to the first side 41, that is, the second abutting portion 453 is used to abut against the cutting tool assembly 30. Specifically, the length of the second abutting portion 453 in the circumferential direction of the brake sleeve 45 is less than the length of the sleeve body 452 in the circumferential direction of the brake sleeve 45. In this way, the brake sleeve 45 abuts against the cutting tool assembly 30 through the second abutting portion 453, which can reduce the contact area between the brake sleeve 45 and the cutting tool assembly 30, so as to reduce the frictional resistance between the brake sleeve 45 and the cutting tool assembly 30, and further reduce the influence on the rotation speed of the cutting tool assembly 30, and thus reduce the influence on the processing efficiency of the material processing equipment of this embodiment.

[0058] The number of the second abutting portions 453 can be multiple, and the multiple second abutting portions 453 are sequentially and spaced apart along the circumferential direction of the brake sleeve 45. Figure 4 The case where the number of the second abutting portions 453 is two is shown. The two second abutting portions 453 are spaced apart from each other along the circumferential direction of the brake sleeve 45. For the sake of example only, the number and distribution mode of the second abutting portions 453 are not limited thereby.

[0059] Furthermore, the cutting tool assembly 30 is provided with a third abutting portion 312, and the above-mentioned brake sleeve 45 is specifically used to abut against the third abutting portion 312. Specifically, a third abutting portion 312 also protrudes from the outer periphery of the tool bar 31 of the cutting tool assembly 30, that is, the third abutting portion 312 protrudes in a direction away from the tool bar 31, as shown in Figure 1 and Figure 3 . The third abutting portion 312 is closer to the bottom of the cup body 50 than the second anti-rotation protrusion 311 on the tool bar 31, and the third abutting portion 312 is used to abut against the brake sleeve 45. Specifically, the second abutting portion 453 of the brake sleeve 45 abuts against the third abutting portion 312 on the tool bar 31.

[0060] In the above manner, after the braking sleeve 45 abuts against the third abutting portion 312, the third abutting portion 312 can prevent the materials in the storage cavity 11 from entering the braking sleeve 45, which can reduce the material residue in the braking sleeve 45 and facilitate the user to clean it.

[0061] Please refer to Figures 1 to 3 、 Figure 5 , Figure 5 which is a schematic structural diagram of an embodiment of the cover body of the present application. Among them, Figure 5 it shows the perspective view looking at the cover body 43 from the second side 42.

[0062] In one embodiment, the cover body 43 is further provided with a limiting sleeve 48. The anti-rotation sleeve 44 and the braking sleeve 45 are embedded in the limiting sleeve 48. A limiting portion 481 protrudes from the inner side wall of the limiting sleeve 48, that is, the limiting portion 481 protrudes towards the braking sleeve 45. The braking sleeve 45 moves towards the first side 41 of the cover body assembly 40 under the action of the elastic member 46, and the first abutting portion 451 of the braking sleeve 45 will also move towards the first side 41 along with the braking sleeve 45. When the first abutting portion 451 of the braking sleeve 45 abuts against the limiting portion 481, the limiting portion 481 will limit the braking sleeve 45 from disengaging from the limiting sleeve 48, that is, limit the maximum displacement of the braking sleeve 45 moving towards the first side 41.

[0063] In one embodiment, one of the inner side wall of the limiting sleeve 48 and the outer periphery of the first abutting portion 451 is provided with a guiding rib 61, and the other is provided with a guiding groove 62, wherein the guiding rib 61 extends along the relative direction of the first side 41 and the second side 42 (as Figure 3 shown by the arrow Z in

[0064] Figure 4 and Figure 5 it shows that the inner side wall of the limiting sleeve 48 is provided with the guiding rib 61, and the outer periphery of the first abutting portion 451 of the braking sleeve 45 is provided with the guiding groove 62. The elastic member 46 is located in the space between the braking sleeve 45 and the guiding rib 61. Moreover, the number of the guiding ribs 61 and the guiding grooves 62 is multiple, and the guiding ribs 61 and the guiding grooves 62 are in one-to-one correspondence and cooperate with each other for clamping. Of course, in other embodiments of the present application, it may also be that the inner side wall of the limiting sleeve 48 is provided with the guiding groove 62, and the outer periphery of the first abutting portion 451 of the braking sleeve 45 is provided with the guiding rib 61, which is not limited herein.

[0065] The following generally describes the operation process of the material processing equipment according to the embodiments of the present application.

[0066] The cover assembly 40 and the cup body 50 are docked, and the driving assembly 20 is drivingly connected to the cutting tool assembly 30 through the cover assembly 40. At this time, the anti-rotation sleeve 44 is sleeved on the outer periphery of the cutting tool assembly 30. The first anti-rotation protrusion 441 in the anti-rotation sleeve 44 is away from the second side 42 of the cover assembly 40 relative to the second anti-rotation protrusion 311 on the tool shank 31, and the first anti-rotation protrusion 441 does not restrict the rotation of the tool shank 31 and the cutting blade 33 thereon. Moreover, the elastic member 46 urges the brake sleeve 45 to move toward the first side 41 and abut against the third abutting portion 312 on the tool shank 31. The tool shank 31 and the cutting blade 33 thereon operate normally to perform cutting processing on the material in the storage cavity 11.

[0067] After the material processing is completed or when the user accidentally lifts the cover assembly 40, the cover assembly 40 and the cup body 50 are not completely separated. At this time, the first anti-rotation protrusion 441 moves toward the second anti-rotation protrusion 311 as the cover assembly 40 moves away from the cup body 50. After the second anti-rotation protrusion 311 that rotates with the tool shank 31 abuts against the first anti-rotation protrusion 441, the further rotation of the tool shank 31 is restricted to achieve an anti-rotation effect. Moreover, at this time, the brake sleeve 45 still maintains the state of abutting against the third abutting portion 312 of the tool shank 31 under the action of the elastic member 46 to prevent the cutting tool assembly 30 from disengaging from the cup body 50. Then, the cover assembly 40 is continuously lifted, and the cover assembly 40 and the cup body 50 are completely separated. The first abutting portion 451 of the brake sleeve 45 abuts against the limiting portion 481 of the limiting sleeve 48 under the action of the elastic member 46, so that the brake sleeve 45 no longer moves toward the first side 41.

[0068] Please refer to Figures 1 to 2 、 Figure 6 , Figure 6 which is a schematic structural diagram of an embodiment of the scraping wall assembly of the present application.

[0069] In one embodiment, the material processing device further includes a scraping wall assembly 70, and the structure of the scraping wall assembly 70 is independent of the storage vessel 10 and the cutting tool assembly 30. Specifically, the scraping wall assembly 70 includes a first support frame 71 and a second support frame 72. The planes where the first support frame 71 and the second support frame 72 are located are parallel to each other and are spaced apart. The scraping wall assembly 70 includes a scraping arm 73. Both ends of the scraping arm 73 are respectively connected to the first support frame 71 and the second support frame 72, and the scraping arm 73 also extends along the spacing direction of the first support frame 71 and the second support frame 72, as Figure 6 shown.

[0070] Both the first support frame 71 and the second support frame 72 can be in the form of complete rings, as Figure 6As shown. Of course, in other embodiments of the present application, the first support frame and the second support frame may also present an incomplete ring shape, but a broken ring shape. The broken parts of the first support frame and the second support frame can be connected by a scraping arm or other structures.

[0071] Optionally, the scraping arm 73 can be integrally formed with the first support frame 71 and the second support frame 72, or the scraping arm 73 is welded to the first support frame 71 and the second support frame 72, or the scraping arm 73 is fixed to the first support frame 71 and the second support frame 72 by fasteners such as screws. Of course, the connection manner of the scraping arm 73 with the first support frame 71 and the second support frame 72 in this embodiment includes but is not limited to the foregoing several manners.

[0072] After the scraping wall assembly 70 is assembled to the material processing equipment, that is, the scraping wall assembly 70 is placed in the storage cavity 11. The first support frame 71 and the second support frame 72 are respectively disposed around the outer periphery of the cutting tool assembly 30, and the first support frame 71 and the second support frame 72 are spaced apart from each other along the axial direction of the storage cavity 11. The scraping arm 73 is relatively adjacent to the inner wall of the storage cavity 11 with respect to the cutting tool assembly 30. The scraping arm 73 can move relative to the inner wall of the storage cavity 11 as the material moves in the storage cavity 11, so as to scrape the material adhered to the inner wall of the storage cavity 11 through the movement of the scraping arm 73 relative to the inner wall of the storage cavity 11, such as Figure 1 shown.

[0073] By the above method, since the cutting tool assembly 30 applies a shearing force to the material during the cutting process of the material, under the action of this shearing force, the material will move circumferentially along the cutting tool assembly 30 in the storage cavity 11, and the moving material can just drive the scraping arm 73 to move. In other words, the scraping arm 73 of the scraping wall assembly 70 in this embodiment is driven by the material in the storage cavity 11 to move relative to the inner wall of the storage cavity 11 to scrape the material adhered to the inner wall of the storage cavity 11. This embodiment does not use a motor to drive the scraping arm 73 to move as in the prior art, simplifies the control process of the material processing equipment, can conveniently scrape the material adhered to the inner wall of the storage cavity 11, and does not require an additional motor, can reduce the manufacturing cost of the material processing equipment, and finally enables the material in the storage cavity 11 to be fully cut and processed.

[0074] In one embodiment, precisely because the structure of the scraping wall assembly 70 is independent, during the processing of the material, the scraping wall assembly 70 has a crosstalk along the axial direction of the storage cavity 11 (i.e., Figure 1 shown as the up and down direction) and along the direction perpendicular to the axial direction of the storage cavity 11 (i.e., Figure 1 shown as the left and right direction). In particular, the crosstalk of the scraping wall assembly 70 along the left and right direction will cause interference and collision between the scraping wall assembly 70 and the cutting tool assembly 30, affecting the reliability of the material processing equipment.

[0075] In view of this, in this embodiment, the lid assembly 40 and the cup body 50 cooperate to limit the axial movement of the scraping wall assembly 70 along the storage cavity 11, and through the dimensional design of the scraping wall assembly 70, the storage cavity 11, and the cutting tool assembly 30, the scraping wall assembly 70 is prevented from moving axially in the left and right directions, which may cause interference and collision between the scraping wall assembly 70 and the cutting tool assembly 30.

[0076] Specifically, the central axis of the storage cavity 11 and the central axis of the cutting tool assembly 30 coincide, as shown by the dashed line O in Figure 1 . When the central axis of the scraping wall assembly 70 coincides with the central axis of the storage cavity 11 and the central axis of the cutting tool assembly 30 (i.e., the central axis of the tool rod 31), and when a cutting blade 33 rotates to face the scraping arm 73, the minimum distance (such as d1 shown in Figure 1 , the same below) between the scraping arm 73 and the cutting tool assembly 30 in the target direction (such as the direction indicated by the arrow X in Figure 1 ) is greater than the minimum distance (such as d2 shown in Figure 1 ) between the scraping arm 73 and the inner wall of the storage cavity 11 in the target direction. Here, the target direction is parallel to the relative direction between the cutting blade 33 and the scraping arm 73. The minimum distance between the scraping arm 73 and the cutting tool assembly 30 is specifically the minimum distance between the scraping arm 73 and the cutting blade 33 when the scraping arm 73 moves to face the cutting blade 33. The distances d1 and d2 are both described based on the relative cutting blade 33 and scraping arm 73 in Figure 1 .

[0077] In the above manner, since the displacement of the scraping wall assembly 70 in the left and right directions depends on the minimum distance between the scraping arm 73 and the inner wall of the storage cavity 11, when the minimum distance between the scraping arm 73 and the cutting tool assembly 30 is greater than the minimum distance between the scraping arm 73 and the inner wall of the storage cavity 11, even if the scraping wall assembly 70 moves axially in the left and right directions until it abuts against the inner wall of the storage cavity 11, there will be no interference or collision between the scraping wall assembly 70 and the cutting tool assembly 30.

[0078] Please continue to refer to Figure 1. In one embodiment, the distance between the scraping arm 73 and the inner wall of the storage cavity 11 in the above-mentioned target direction is d1, and d1 is the minimum distance between the scraping arm 73 and the inner wall of the storage cavity 11. Among them, 1.99 mm ≤ d1 ≤ 9.99 mm. For example, d1 can be 1.99 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 9.99 mm, etc. In this way, the distance between the scraping arm 73 and the inner wall of the storage cavity 11 can be designed reasonably, avoiding the situation that the distance between the scraping arm 73 and the inner wall of the storage cavity 11 is too small, resulting in too large viscous resistance on the scraping arm 73 and affecting the working efficiency of the scraping arm 73. At the same time, it can also avoid the situation that the distance between the scraping arm 73 and the inner wall of the storage cavity 11 is too large, which affects the effect of the scraping arm 73 scraping the adhered material on the inner wall of the storage cavity 11.

[0079] In one embodiment, the distance between the scraping arm 73 and the above-mentioned one cutting blade 33 in the target direction is d2, and d2 is the minimum distance between the scraping arm 73 and the cutting tool assembly 30. Among them, 0.99 mm ≤ d2 ≤ 5.99 mm. For example, d2 can be 0.99 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 5.99 mm, etc. In this way, the distance between the scraping arm 73 and the cutting tool assembly 30 can be designed reasonably, avoiding the situation that the distance between the scraping arm 73 and the cutting tool assembly 30 is too small, resulting in an increased risk of interference and collision between the scraping arm 73 and the cutting tool assembly 30. At the same time, it can also avoid the situation that the distance between the scraping arm 73 and the cutting tool assembly 30 is too large, resulting in too low speed of the scraping arm 73 relative to the inner wall of the storage cavity 11 and affecting the working efficiency of the scraping arm 73. This is because the material is driven by the cutting tool assembly 30, and the material closer to the cutting tool assembly 30 moves faster, which can drive the scraping arm 73 to move at a faster speed.

[0080] Please refer to Figure 7 and Figure 8 , Figure 7 which is a schematic diagram of the first orthographic projection of the first end of the scraping wall assembly of the present application on the reference plane, Figure 8 and

[0081] Figure 1 is a schematic diagram of the second orthographic projection of the second end of the scraping wall assembly of the present application on the reference plane. In one embodiment, the scraping wall assembly 70 has a first end and a second end. The first end is provided with a first support frame 71, and the second end is provided with a second support frame 72. The first support frame 71 is farther from the bottom of the storage cavity 11 than the second support frame 72. The first end has a first orthographic projection 711 on the reference plane (such as

[0082] The distance between any two points on the first orthographic projection 711 has a maximum value d3, and the distance between any two points on the second orthographic projection 721 has a maximum value d4, where d3 > d4. In other words, the size of the end where the first support bracket 71 is located is larger than the size of the end where the second support bracket 72 is located. Since the cup body 50 in this embodiment has a form with a large cup mouth size and a small cup bottom size, the larger cup mouth size can facilitate the docking of the cup body 50 and the cover assembly 40 and the addition of materials into the cup body 50. The form of the cup body 50 with a large cup mouth size and a small cup bottom size makes the inner side wall of the cup body 50 present an inclined form. To match the structure of the cup body 50, in this embodiment, the size of the end where the first support bracket 71 is located is larger than the size of the end where the second support bracket 72 is located, so that the scraping arm 73 is inclined, so that the scraping arm 73 is as parallel as possible to the inner side wall of the cup body 50, ensuring that the scraping arm 73 can efficiently scrape off the materials adhered to various positions on the inner side wall of the cup body 50.

[0083] Furthermore, 129.9 mm ≤ d3 ≤ 149.9 mm. For example, d3 is 129.9 mm, 130 mm, 135 mm, 140 mm, 145 mm, 149.9 mm, etc. And, 109.9 mm ≤ d4 ≤ 129.9 mm. For example, d4 is 109.9 mm, 110 mm, 115 mm, 120 mm, 125 mm, 129.9 mm, etc. It is precisely because of the such size design of the end where the first support bracket 71 is located and the end where the second support bracket 72 is located that the scraping wall assembly 70 has the above distance relationship with the inner side wall of the storage cavity 11 and the cutting tool assembly 30 after being built into the storage cavity 11.

[0084] In one embodiment, the number of scraping arms 73 is multiple. The multiple scraping arms 73 are sequentially and evenly spaced along the circumferences of the first support bracket 71 and the second support bracket 72. Further, the multiple scraping arms 73 can be evenly spaced along the circumferences of the first support bracket 71 and the second support bracket 72. In this way, by arranging multiple scraping arms 73 around the first support bracket 71 and the second support bracket 72, the efficiency of the scraping arms 73 in scraping off the materials adhered to the inner side wall of the storage cavity 11 can be improved.

[0085] Figure 6 It shows that there are four scraping arms 73 evenly spaced around the first support bracket 71 and the second support bracket 72. This is only for example and does not limit the number of scraping arms 73 accordingly.

[0086] In one embodiment, the wall scraper assembly 70 further includes a reinforcing crossbeam 74. Since the first support frame 71 is far away from the bottom of the container chamber 11 relative to the second support frame 72, the first support frame 71 is provided with a reinforcing crossbeam 74, and the two ends of the reinforcing crossbeam 74 are respectively provided at different parts of the first support frame 71. The reinforcing crossbeam 74, as the name implies, plays the role of reinforcing the support frame. In this embodiment, by providing the reinforcing crossbeam 74 on the first support frame 71, it is beneficial to improve the overall stability and reliability of the wall scraper assembly 70, so as to avoid reliability problems as much as possible.

[0087] During the assembly of the scraper assembly 70 of this embodiment, the second support frame 72 needs to pass through the cutting blade assembly 30. If a reinforcing crossbeam 74 is provided on the second support frame 72, the reinforcing crossbeam 74 is likely to interfere with or collide with the cutting blade 33 of the cutting blade assembly 30, thereby affecting the reliability of the entire material processing equipment. Therefore, in this embodiment, the reinforcing crossbeam 74 is provided on the first support frame 71, which can not only improve the overall stability and reliability of the scraper assembly 70, but also avoid interference and collision between the reinforcing crossbeam 74 and the cutting blade 33 of the cutting blade assembly 30, thereby avoiding affecting the reliability of the entire material processing equipment as much as possible.

[0088] In one embodiment, the inner wall of a conventional household food preparation device is usually provided with blocking ribs to improve the crushing effect of the material. However, in this embodiment, due to the existence of the scraper assembly 70, the inner wall surface of the container cavity 11 is flat, that is, the inner wall surface of the cup body 50 is flat, and no blocking ribs are provided to avoid the blocking ribs hindering the movement of the scraper assembly 70 and to avoid the blocking ribs affecting the scraper assembly 70 to scrape the material adhered to the inner wall surface of the container cavity 11.

[0089] See also Figure 1 , Figures 9 to 11 , Figure 9 is a schematic diagram of a top view of an embodiment of a cutting blade assembly of the present application, Figure 10 yes Figure 9 The schematic diagram of the cross-sectional structure of the cutting tool assembly in the AA direction is shown. Figure 11 It is a schematic structural diagram of an embodiment of a cutting blade of the present application.

[0090] In one embodiment, the cutting blade 33 includes a cutting portion 331 and a connecting portion 332. The cutting portion 331 is connected to the cutter bar 31 through the connecting portion 332, and the cutting portion 331 is used to cut materials. Figure 9 The two ends of the cutting part 331 are the material receiving end 333a and the material discharging end 333b. The material moves from the material receiving end 333a to the material discharging end 333b relative to the cutting part 331. The thickness of the material receiving end 333a is t, where 0.99mm≤t≤2.99mm, for example, t is 0.99mm, 1mm, 2mm, 2.99mm, etc.

[0091] In the above manner, the thickness of the material receiving end 333a is t, where 0.99 mm ≤ t ≤ 2.99 mm. This means that the material receiving end 333a of the cutting part 331 has a blunt structure, and the cutting part 331 performs cutting by slapping the material, which can avoid overly fine cutting of the material, and thus can be adapted to application scenarios such as processing meatballs and minced meat. Moreover, the thickness of the cutting part 331 in this embodiment is reasonably designed. It can not only ensure that the thickness of the cutting part 331 is not too large to avoid low processing efficiency, but also ensure that the thickness of the cutting part 331 is not too small to avoid overly fine cutting of the material, and can be adapted to application scenarios such as processing meatballs and minced meat. Therefore, it can balance processing efficiency and the effect of the processed meatballs and minced meat.

[0092] It should be noted that the thickness of a component is defined as the length of the component in the direction perpendicular to the plane it is in. For example, as Figure 9 shown, if the plane where the cutting part 331 is located (such as Figure 9 the middle plane α shown) is perpendicular to the axial direction of the tool bar 31, then the thickness of the cutting part 331 is the length of the cutting part 331 in the axial direction of the tool bar 31; as shown below Figure 12 shown, if the plane where the extension part 335 of the cutting part 331 extends along the axial direction of the tool bar 31, then the thickness of the extension part 335 is the length of the extension part 335 in the direction away from the tool bar 31.

[0093] Furthermore, the thickness of each position of the cutting part 331 is t. Even further, the thickness of each position of the cutting part 331 is equal, that is, the upper and lower surfaces of the cutting part 331 in the axial direction of the tool bar 31 are planes. In this way, it is beneficial to reduce the resistance suffered by the cutting blade 33 during the process of cutting the material, and is beneficial to ensuring the cutting efficiency of the material.

[0094] Please continue to refer to Figure 9 . In an embodiment, the positive projection of the outer edge of the material receiving end 333a on the reference plane (such as Figure 9 the middle plane α shown) is arc-shaped, where the reference plane is perpendicular to the axial direction of the tool bar 31. In this way, the outer edge of the material receiving end 333a is different from the straight-edge structure of the edge of a traditional cutting tool. The arc-shaped design of the outer edge of the material receiving end 333a in this embodiment is beneficial to extending the length of the material receiving end 333a, that is, increasing the contact area between the cutting part 331 and the material, and further beneficial to improving the processing efficiency of the material, and can complete the processing of meatballs and minced meat in a shorter time.

[0095] Furthermore, the positive projection of the outer edge of the material receiving end 333a on the reference plane is circular arc-shaped, and the radius of the corresponding circular arc of the positive projection is R, as Figure 9As shown. Among them, 30mm ≤ R ≤ 80mm. For example, R is 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, etc. In this way, R will not be too large, which can avoid the contact area between the cutting blade 33 and the material from being too large, resulting in the material being cut too finely. And R will not be too small, which can avoid the contact area between the cutting blade 33 and the material from being too small, resulting in a low processing efficiency of the material.

[0096] Please continue to refer to Figure 1 . In one embodiment, the end of the cutting part 331 away from the tool bar 31 is the target end 336. The minimum distance between the target end 336 and the inner wall of the storage cavity 11 (i.e., the inner wall of the cup body 50) in the preset direction is w. The preset direction passes through the central axes of the target end 336 and the tool bar 31, and the preset direction is parallel to Figure 1 the direction indicated by the arrow X in

[0097] Please refer to Figure 1 and Figure 12 , Figure 12 which is a schematic structural diagram of another embodiment of the cutting tool assembly of the present application.

[0098] In one embodiment, the number of the cutting blades 33 is multiple. At least some of the cutting blades 33 are arranged at intervals along the axial direction of the tool bar 31. That is to say, some of the cutting blades 33 can be arranged at intervals along the axial direction of the tool bar 31, while some of the cutting blades 33 are located at the same position on the axial direction of the tool bar 31; or, the multiple cutting blades 33 are sequentially arranged at intervals along the axial direction of the tool bar 31, and no two cutting blades 33 are located at the same position on the axial direction of the tool bar 31.

[0099] By the above method, cutting blades 33 are provided at different positions on the axial direction of the tool bar 31, so that the materials at different height positions in the storage cavity 11 can all be cut by the cutting blades 33, which is beneficial to ensuring that the materials in the storage cavity 11 are all cut sufficiently.

[0100] Furthermore, as Figure 1As shown, the cutting blade 33 closest to the bottom of the storage cavity 11 is the target cutting blade 337, and the minimum distance between the target cutting blade 337 and the bottom of the storage cavity 11 is h, that is, the minimum distance between the target cutting blade 337 and the bottom of the cup body 50 is h. Among them, 1.99 mm ≤ h ≤ 7.99 mm. For example, h is 1.99 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 7.99 mm, etc. In this way, it is possible to avoid the risk that the distance between the target cutting blade 337 and the bottom of the storage cavity 11 is too small, resulting in interference and collision between the target cutting blade 337 and the bottom of the storage cavity 11. At the same time, it is possible to avoid the distance between the target cutting blade 337 and the bottom of the storage cavity 11 being too large, which may lead to an overly large overall height dimension of the material processing equipment and is not conducive to the miniaturization design of the material processing equipment.

[0101] Please continue to refer to Figure 12 . In one embodiment, the cutting portion 331 includes a main body portion 334 and an extension portion 335. The extension portion 335 is connected to the tool bar 31 through the main body portion 334, and the main body portion 334 is closer to the tool bar 31 than the extension portion 335. The extending direction of the main body portion 334 (as shown by the arrow X in Figure 12 ) is perpendicular to the axial direction of the tool bar 31 (as shown by the arrow Z in Figure 12 ), and the extending direction of the extension portion 335 is parallel to the axial direction of the tool bar 31. That is to say, the end of the cutting portion 331 away from the tool bar 31 in this embodiment, that is, the extension portion 335, is folded along the axial direction of the tool bar 31. In this way, without changing the length of the cutting portion 331 along the radial direction of the tool bar 31, the extension portion 335 increases the contact area between the cutting portion 331 and the material, which is beneficial to improving the processing efficiency of the material.

[0102] In addition, in this application, unless otherwise clearly specified and limited, terms such as "connected", "connected to", "stacked" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0103] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of this application.
