DETAILED DESCRIPTION

[0043] In the following description, a large number of details are provided so that the present application can be thoroughly understood. However, it can be appreciated by those skilled in the art that the following description only exemplarily shows the preferred embodiments of the present application, and the present application can be implemented without one or more such details. In addition, in order to avoid confusion with the present application, some technical features known in the art are not described in detail.

[0044] A cutter assembly is provided in the embodiments of the present application. The cutter assembly can be applied to any type of food crushing device to cut and crush food materials. In combination with the description of the cutter assembly, the cutter assembly can be applied to any type of food crushing device to cut and crush food materials. In combination with the description of the cutter assembly, Figure 1 , Figure 3 and Figure 5, the food material crushing device can include a cup assembly 20. The cutter assembly 10 can include a cutter disc 110 rotatably mounted in the cup assembly 20 in a predetermined plane, and the cutter disc 110 can be disc-shaped. The predetermined plane can be understood as the rotation plane of the cutter disc 110, and the predetermined plane and the rotation axis of the cutter disc 110 satisfy the vertical condition. The cutter disc 110 can be provided with a first transmission groove 1112, and a transmission shaft 150 is connected to the first transmission groove 1112. The motor output shaft of the food material crushing device can be linked to the transmission shaft 150 for transmission, that is, the motor drives the cutter disc 110 to rotate. The cutter disc 110 can be divided into a first processing cavity 101 and a second processing cavity 102 in the cup assembly 20. The first processing cavity 101 and the second processing cavity 102 can be located on opposite sides of the cutter disc 110 and communicate with each other, and the cutter disc 110 can include a disc body 1110 and a first cutting knife provided on the disc body 1110. The first side of the cutter disc 110 and the cup assembly 20 form the first processing cavity 101, and the second side of the cutter disc 110 and the cup assembly 20 form the second processing cavity 102. The first side and the second side are opposite sides in the axial direction of the cutter disc 110. The first processing cavity 101 and the second processing cavity 102 can each be provided with a processing structure for processing food materials. It can be understood that the cutter disc 110 can play a role in separating and blocking, that is, two processing cavities are separated. For example, the right side of the cutter disc 110 is the first side and the left side is the second side. When the cutter assembly 10 is working, the rotation of the cutter disc 110 stirs the food materials in the cup assembly 20. Since the first processing cavity 101 and the second processing cavity 102 communicate with each other, the food materials flow in the two processing cavities and form a circulation, and the rotation of the cutter disc 110 contacts the food materials to crush the food materials in the circulation. This process can be understood as a crushing cycle in which the cutter assembly 10 cuts and crushes the food materials. The communication between the first processing cavity 101 and the second processing cavity 102 can be achieved in one or a combination of multiple ways, for example, through a gap 103, through a slot 1111 provided on the cutter disc 110, or through other hollow structures provided on the cutter disc 110. Figure 1

[0045] Compared with the cutting blade scheme, the cutter assembly 10 provided by the present application is arranged to reduce the occurrence of food materials being stuck between adjacent two cutting blades during rotation, that is, to reduce the probability of the cutter disc 110 being stuck by hard objects and to reduce the risk of motor lock. The disc-shaped arrangement can reduce the resistance between the cutter disc 110 and the food materials during rotation. Moreover, the first processing cavity 101 and the second processing cavity 102 communicate with each other, and in cooperation with the cutter disc 110, a crushing cycle is formed, and the crushing effect is good.

[0046] Referring to Figure 3 ​The outer periphery of the cutter disc part 110 can have a gap 103 with the cup assembly 20, and the gap 103 can communicate the first processing cavity 101 and the second processing cavity 102. That is, the broken materials in the first processing cavity 101 and the second processing cavity 102 can flow through the gap 103. The size of the gap 103 can be set according to the use requirement. In this way, the food materials form a broken circulation of the first processing cavity 101, the gap 103, and the second processing cavity 102 in the cup assembly 20, and the circulation is smoother, and the broken effect is good.

[0047] With reference to Figure 5 , Figure 6 , Figure 9 , Figure 13 and Figure 17 , the disc body 1110 is provided with a slot 1111, the slot 1111 communicates the first processing cavity 101 and the second processing cavity 102, and the first cutting knife 1120 is arranged along the slot 1111 and extends from one side slot wall to the other side slot wall. The slot 1111 can extend along the middle part of the disc body 1110 to the edge. The first cutting knife 1120 can be detachably mounted on the disc body 1110, or the first cutting knife 1120 and the disc body 1110 can be an integral part. When the cutter assembly 10 works, the disc body 1110 rotates, and the first cutting knife 1120 rotates and contacts the broken materials to cut and break. In this way, the broken circulation is further improved. The disc body 1110 itself rotates to have the effect of stirring the food materials, so that the resistance of the first cutting knife 1120 rotating with the disc body 1110 can be smaller. In an embodiment not shown, the first cutting knife can be arranged at the outer edge of the cutter disc part.

[0048] With reference to Figure 3 , Figure 4 and Figure 7 , the first cutting knife 1120 can include a connecting end 1121 connected with the disc body 1110 and a cutting end 1122 away from the connecting end 1121. In the axial direction of the cutter disc part 110, the cutting end 1122 is arranged spaced apart from the disc body 1110 and forms a flow-through passage between the first cutting knife 1120 and the disc body 1110, and the flow-through passage can communicate with the slot 1111. One side of the flow-through passage communicates with the slot 1111, and the other side communicates with the first processing cavity 101 or the second processing cavity 102. It should be noted that in the embodiments shown in the present application, the flow-through passages are all located on the side of the slot 1111 close to the first side, which depends on the position of the first cutting knife 1120. In an embodiment not shown, the first cutting knife can be located on the side of the cutter disc part facing the second side, and correspondingly, the flow-through passage is located on the side of the slot close to the second side.

[0049] The first cutting knife 1120 is arranged along one side groove wall to the other side groove wall of the slot 1111, and the cutting end 1122 is arranged spaced apart from the disc body 1110, that is, the first cutting knife 1120 extends from one side groove wall to the other side groove wall and is inclined to the first side or the second side. In operation, the disc body 1110 and the first cutting knife 1120 rotate, and the food material entering the flow passage contacts the first cutting knife 1120 and is extruded by the first cutting knife 1120 (for example, extruded downward in the view angle), so that the crushing cycle is more smooth. It can be understood that the inclination direction of the first cutting knife 1120 can be consistent with the rotation direction of the cutter assembly 10. Moreover, the food material in the first processing cavity 101 and the second processing cavity 102 can enter the opposite side through the flow passage and the slot 1111. When the food material enters the flow passage, the cutting end 1122 contacts the food material, that is, cuts the food material. In this way, the crushing effect of the crushing cycle process can be better improved, that is, the cutter assembly 10 crushes the food material more fully and better. Figure 3 It can be understood that the inclination direction of the first cutting knife 1120 can be consistent with the rotation direction of the cutter assembly 10. Moreover, the food material in the first processing cavity 101 and the second processing cavity 102 can enter the opposite side through the flow passage and the slot 1111. When the food material enters the flow passage, the cutting end 1122 contacts the food material, that is, cuts the food material. In this way, the crushing effect of the crushing cycle process can be better improved, that is, the cutter assembly 10 crushes the food material more fully and better.

[0050] With reference to Figure 4 , Figure 7 , Figure 8 and Figure 11 , the cutting end 1122 and the connecting end 1121 can form a first cutting surface 1123 facing the disc body 1110, and the first cutting surface 1123 can have a first included angle a1 with the predetermined plane, 20°≤a1≤60°. For example, the first included angle a1 can be 20°, 30° or 60°, and the like. The first cutting surface 1123 arranged in this way can on the one hand ensure the extrusion of the food material and ensure the smoothness of the crushing cycle, and on the other hand ensure the cutting effect of the food material. Of course, the angle of the first cutting surface 1123 can be set to any other setting according to the use requirement. The side of the first cutting knife 1120 facing the disc body 1110 can have a plurality of cutting surfaces, and the first cutting surface 1123 is one of the plurality of cutting surfaces. Alternatively, the side of the first cutting knife 1120 facing the disc body 1110 can be an arc surface.

[0051] With reference to Figure 7 , Figure 11 , Figure 15 and Figure 19 , the cutting end 1122 and the connecting end 1121 can form a second cutting surface 1124 facing away from the disc body 1110, and the second cutting surface 1124 can have a second included angle a2 (not shown in the figure) with the predetermined plane, 0≤a2≤50°. For example, the second included angle a2 can be 0, 30° or 60°, and the like. Among them, the second included angle of 0 can be understood as that the second cutting surface 1124 is arranged parallel to the predetermined plane (for example, the second cutting surface 1124 is arranged perpendicular to the disc body 1110).Figure 7 、 Figure 11 、 Figure 15 ). The smaller the angle between the second cutting surface 1124 and the predetermined plane, the better the structural strength of the first cutting knife 1120 and the disc body 1110 can be ensured. The angle between the second cutting surface 1124 and the predetermined plane can improve the crushing effect of the first cutting knife 1120 on the food material. The second cutting surface 1124 is thus arranged to better balance the structural strength and crushing effect of the first cutting knife 1120 and the disc body 1110, ensuring the stability and crushing effect of the cutter assembly 10. Of course, in an embodiment not shown, the angle of the second cutting surface can be set to any other arrangement according to the use requirements.

[0052] Referring to Figure 7 and Figure 19 , the cutting end 1122 and the predetermined plane can have a distance H1, 0.4mm≤H1≤2.5mm. For example, H1 can be 0.4mm, 0.5mm, 1.0mm or 2.5mm, etc. It can be understood that the distance between the cutting end 1122 and the predetermined plane can affect the amount of food material passing into the gap 103 and the slot 1111. Moreover, when the disc body 1110 and the first cutting knife 1120 rotate, the resistance experienced by H1 is also different. This arrangement can make the amount of food material passing through the flow passage and the slot 1111 more moderate, and avoid excessive resistance, ensuring the overall crushing effect of the cutter assembly 10. In an embodiment not shown, the distance between the cutting end and the predetermined plane can be set to any other arrangement according to the use requirements.

[0053] The disc body 1110 and the predetermined plane can have a third included angle a3 (not shown in the figure), 0≤a3≤5°. For example, the third included angle a3 can be 0, 1°, 2.5° or 5°, etc. Among them, a3=0 can be understood as the disc body 1110 being parallel to the predetermined plane, as Figure 7 、 Figure 11 、 Figure 15 and Figure 19 . When working, the smaller the angle between the disc body 1110 and the predetermined plane, the smaller the resistance experienced by the disc body 1110, but the crushing cycle is relatively weak. Correspondingly, the larger the angle between the disc body 1110 and the predetermined plane, the more intense the crushing cycle in the first processing cavity 101 and the second processing cavity 102, which can improve the crushing effect, but excessive resistance will affect the rotation of the disc body 1110 and thus affect the crushing effect. This arrangement can better balance the resistance experienced by the disc body 1110 and the crushing effect, ensuring that the cutter assembly 10 has a good crushing effect on the food material.

[0054] The first cutting knife 1120 extends along a predetermined track. The predetermined track can be linear, and the linear track can pass through the center of the disc body 1110, as shown in Figure 4 、 Figure 5 、 Figure 6 、 Figure 16 、 Figure 17 and Figure 18 . In this way, the structural strength of the disc body 1110 and the first cutting knife 1120 can be better ensured. When the grooves 1111 are multiple, the multiple grooves 1111 can be arranged symmetrically with the center of the disc body 1110. Alternatively, the predetermined track is linear, and the linear track can be arranged offset from the center of the disc body 1110, as shown in Figure 8 、 Figure 9 and Figure 10 . That is, the grooves 1111 can be arranged eccentrically, so that the length of the grooves 1111, i.e. the length of the first cutting knife 1120, can be increased, and the crushing effect can be improved, without changing the size of the disc body 1110.

[0055] In combination with reference to Figure 12 、 Figure 13 、 Figure 14 and Figure 15 , the first cutting knife 1120 extends along a predetermined track, and the predetermined track can be arc-shaped, and the first cutting knife 1120 is arranged in parallel with the predetermined track. The arc-shaped grooves 1111 and the first cutting knife 1120 can better avoid the jamming of the crushed material, the length of the first cutting knife 1120 can be larger, and the crushing effect is better.

[0056] In combination with reference to Figure 4 、 Figure 8 、 Figure 12 and Figure 16 , the groove 1111 can pass through to the outer edge of the disc body 1110, and the first cutting knife 1120 extends along the groove wall on one side of the groove 1111 and is arranged. In the radial direction of the disc body 1110, the outer edge of the first cutting knife 1120 is flush with the outer edge of the disc body 1110. That is, the outer edge of the first cutting knife 1120 does not protrude from the disc body 1110. In this way, the length of the first cutting knife 1120 can be as long as possible without changing the size of the disc body 1110, and the first cutting knife 1120 can avoid excessive resistance. The groove 1111 passing through to the outer edge of the disc body 1110 can reduce the jamming of the crushed material in the groove 1111.

[0057] Referring to Figure 6 、 Figure 10 、 Figure 14 and Figure 18The plurality of grooves 1111 can be arranged at intervals in the circumferential direction of the disc body 1110, and at least some of the plurality of grooves 1111 can be provided with the first cutting knife 1120. That is, some of the plurality of grooves 1111 can be provided with the first cutting knife 1120, or all of the grooves 1111 can be provided with the first cutting knife 1120. In this way, more first cutting knives 1120 are involved in the crushing cycle, and the crushing effect of the cutter assembly 10 is better.

[0058] With reference to Figure 1 , Figure 2 and Figure 3 , the cutter assembly 10 can further include a second cutting knife 130 rotatably arranged on the side of the disc body 1110 facing the first processing cavity 101. The second cutting knife 130 can be provided with a second transmission groove, and the transmission shaft 150 can pass through the first transmission groove 1112 and the second transmission groove, so that the motor drives the second cutting knife 130 and the first cutting knife 1120 to rotate together. The second cutting knife 130 can crush the crushed material in the first processing cavity 101, further improving the crushing effect of the cutter assembly 10. In an embodiment not shown, the first processing cavity can not have a cutting knife. For example, the cutter assembly can include a first cutting knife and a third cutting knife.

[0059] With reference to Figure 3 , the second cutting knife 130 can have a third cutting surface 1310, and the third cutting surface 1310 and the predetermined plane can form a fourth included angle a4, 25°≤a4≤65°. For example, the third cutting surface 1310 and the predetermined plane can form an included angle of 25°, 40° or 65°, etc. In this way, the crushing effect of the second cutting knife 130 is better. The fourth included angle a4 can be greater than the first included angle a1 and / or the second included angle a2. The orthographic projection of the second cutting knife 130 in the predetermined plane can fall within the orthographic projection of the disc body 1110 and the first cutting knife 1120 in the predetermined plane. In an embodiment not shown, the cutting surface of the second cutting knife can be at any other angle.

[0060] With reference to Figure 1 , Figure 2 and Figure 3The cutter assembly 10 can further include a third cutting knife 140, which can be arranged on the side of the disc body 1110 facing the second processing cavity 102. The third cutting knife 140 can be provided with a third transmission groove, and the transmission shaft 150 can pass through the first transmission groove 1112 and the third transmission groove, so that the motor drives the third cutting knife 140 and the first cutting knife 1120 to rotate together. The third cutting knife 140 can crush the crushed materials in the second processing cavity 102, further improving the crushing effect of the cutter assembly 10. In an embodiment not shown, the second processing cavity can not have a cutting knife. For example, the cutter assembly can include a first cutting knife and a second cutting knife.

[0061] With reference to Figure 1 , Figure 5 , Figure 9 , Figure 13 and Figure 17 The third cutting knife 140 has a fourth cutting surface 1410, and the fourth cutting surface 1410 has a fifth included angle a5 (not shown in the figure) with the predetermined plane, 25°≤a5≤65°. For example, the included angle between the fourth cutting surface 1410 and the predetermined plane is 25°, 40° or 65°, etc. In this way, the crushing effect of the third cutting knife 140 is better. The orthographic projection of the third cutting knife 140 in the predetermined plane can fall within the orthographic projection of the disc body 1110 and the first cutting knife 1120 in the predetermined plane. The fifth included angle a5 can be greater than the first included angle a1 and / or the second included angle a2. The fourth included angle a4 between the third cutting surface 1310 and the predetermined plane and the fifth included angle a5 between the fourth cutting surface 1410 and the predetermined plane can be the same. The diameter of the third cutting knife 140 can be greater than the diameter of the second cutting knife 130. In an embodiment not shown, the cutting surface of the third cutting knife can be at any other angle.

[0062] According to another aspect of the present application, a food crushing device is also provided. With reference to Figure 1 , Figure 2 and Figure 3The food crushing device can include any one of the cutter assembly 10 and the cup assembly 20 described above. The cup assembly 20 forms a closed cooking space inside, and the cutter assembly 10 can be located in the cooking space, and the first processing cavity 101 and the second processing cavity 102 can be formed in the cooking space. The cup assembly 20 can include a cup seat 210 and a cup body 220 that is detachably mounted to the cup seat 210. The food crushing device can further include a motor assembly, an output end of the motor assembly being connected with the transmission shaft 150, and the transmission shaft 150 being connected with the disc body 1110 through the cup seat 210. Since the cutter assembly 10 adopts the technical solutions of any one of the embodiments described above, the food crushing device at least has the beneficial effects brought by the technical solutions of the embodiments described above, which will not be repeated here. The food crushing device can be any device that needs to cut and crush food materials, including but not limited to food material processors, coffee machines, etc.
