Technical Field

[0001] The present application relates to the technical field of small household appliances, and in particular to a knife disc assembly, a blender cup assembly and a food processor. Background Art

[0002] The food processor includes a mixing cup, a blade assembly and a driving device. The blade assembly includes a blade disc, a bearing seat, a bearing assembly and a blade assembly. The bearing assembly is assembled to the bearing seat. The bearing seat is assembled to the blade disc. The blade assembly is connected to the bearing assembly. The blade disc is located at the bottom of the mixing cup and forms a food processing space with the mixing cup. The driving device drives the blade assembly to rotate in the food processing space to process food, such as making soy milk, squeezing juice, etc.

[0003] In the above-mentioned cutter disc assembly, the bearing assembly is easy to fall off from the bearing seat. Utility Model Content

[0004] The purpose of the present application is to disclose a blade disc assembly, a mixing cup assembly and a food processor. The bearing assembly of the blade disc assembly will not fall off from the bearing seat.

[0005] In a first aspect, the present application discloses a cutter disc assembly. The cutter disc assembly includes a cutter disc, a bearing assembly, and a cutter assembly. The cutter disc is provided with a bearing seat, and the bearing seat has a mounting cavity; the bearing assembly includes an inner liner and a bearing fastened in the inner liner; the inner liner includes an insertion portion inserted into the mounting cavity; the insertion portion and the inner wall of the mounting cavity are connected by a connecting structure; the cutter assembly includes a cutter shaft assembled with the bearing and a blade located above the cutter disc.

[0006] As described above, since the connection structure connects the liner to the bearing seat, the bearing assembly can be firmly assembled to the bearing seat through the connection structure, for example, the bearing assembly is not easy to fall off. Furthermore, the insertion portion of the liner is inserted into the installation cavity, so that the outer wall of the insertion portion of the liner contacts the inner wall of the installation cavity, thereby ensuring the concentricity of the bearing assembly and the knife shaft.

[0007] In some embodiments, the connection structure includes a groove and a protrusion. One of the inner wall of the installation cavity and the outer wall of the insertion portion is provided with the groove, and the other is provided with the protrusion, and the protrusion is located in the groove.

[0008] As configured above, by virtue of the protrusion being located in the groove, a force acting along the axial direction of the knife shaft is generated between the protrusion and the groove, thereby preventing the bearing assembly from falling off.

[0009] In some embodiments, the groove is located on the outer wall of the insert, the protrusion is located on the inner wall of the installation cavity, the groove surrounds the circumference of the cutter head assembly, and the protrusions are spaced apart in the circumference of the cutter head assembly. Alternatively, both the groove and the protrusion surround the circumference of the cutter head assembly.

[0010] As described above, no matter the groove surrounds the cutter disc assembly, the protrusions are arranged at intervals, or the groove and the protrusions surround the cutter disc assembly, because the groove is one circle, the protrusion can enter the groove at any position in the circumferential direction, so the bearing assembly is not only easier to assemble with the protrusion of the cutter disc, but also the bearing assembly is not easy to fall off from the bearing seat of the cutter disc.

[0011] In some embodiments, the liner is a plastic part, a silicone part or a powder metallurgy part.

[0012] As set up above, the liner is a plastic part or a silicone part, and is inserted into the installation cavity in combination with the insertion portion of the liner. In this way, the liner can play a buffering role and can effectively reduce the movement of the bearing assembly caused by the knife assembly stirring food, thereby extending the life of the bearing assembly and the life of the knife shaft, avoiding friction loss caused by vibration, and thus reducing the risk of water leakage.

[0013] In some embodiments, the bearing seat and the cutter disc are integrally formed.

[0014] As set up as above, since the bearing seat and the cutter disc are integrally formed, welding of the bearing seat and the cutter disc is avoided. There is no welding point at the intersection of the bearing seat and the main body of the cutter disc. On the one hand, no welding process is required, which can reduce costs. On the other hand, since no welding process is required, there are no welding points, which can avoid rusting of the welding points and can also avoid water leakage caused by falling off of the welding points. Unlike the threaded connection between the bearing seat and the cutter disc, there will be no water leakage due to loose threads.

[0015] In some embodiments, the cutter disc includes a mounting portion located laterally to the bearing seat and opposite to the bearing seat; the liner includes a fixing portion located laterally to the insertion portion, and the fixing portion is fixedly connected to the mounting portion.

[0016] As described above, after the bearing assembly and the cutter shaft are assembled as a whole, they are pressed into the installation cavity as a whole, and then the fixing portion is fixedly connected to the installation portion, so that the assembly of the cutter disc assembly is simple. In addition, since the fixing portion is located on the side of the insertion portion, and the installation portion is located on the side of the bearing seat, when the fixing portion and the installation portion are in contact, the bearing assembly cannot be pressed in again, preventing the cutter disc from being damaged. Moreover, the combination of the fixed connection and the connection structure further ensures that the bearing assembly will not fall off the bearing seat.

[0017] In some embodiments, the cutter disc assembly further includes at least one of the following features: a) the fixing portion and the mounting portion are welded, screwed, or integrally formed to achieve the fixed connection; b) the fixing portion surrounds the insertion portion; the mounting portion surrounds the bearing seat; c) the mounting portion is a step.

[0018] As described above, the liner and the cutter disc are conveniently assembled by welding, screw connection or integral molding. Since the fixing portion surrounds the insertion portion, and the mounting portion surrounds the bearing seat, the liner and the cutter disc have more contact points, the cutter disc and the liner are firmly assembled, and the bearing assembly is not easy to fall off. Since the mounting portion is a step, it can play a positioning role, making it easier to assemble the liner and the cutter disc.

[0019] In some embodiments, the liner includes a bearing mounting cavity for accommodating the bearing and a accommodating cavity connected to the bearing mounting cavity; the cutter disc assembly includes a seal, which is located in the accommodating cavity and is used to seal the top gap between the liner and the bearing seat.

[0020] As set up as above, it is only necessary to place the seal in the accommodating cavity, and after the bearing assembly is pressed into the installation cavity, the seal seals the top gap between the liner and the bearing seat. The installation of the seal is simple because the aforementioned tight contact makes the sealing effect good.

[0021] In a second aspect, the present application discloses a stirring cup assembly, which comprises a stirring cup and any one of the aforementioned knife disc assemblies, wherein the knife disc and the stirring cup form a food processing cavity.

[0022] As configured above, the blending cup assembly has at least the beneficial effects of the blade disc assembly, which will not be described in detail.

[0023] In a third aspect, the present application discloses a food processor, which comprises a mixing cup, a driving device, and any one of the aforementioned blade disc assemblies; the driving device drives the blade assembly to rotate in the mixing cup.

[0024] As configured above, the food processor at least has the beneficial effects of the blade assembly, which will not be described in detail. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] First, see Figure 1 , Figure 3 and Figure 4 The present application discloses a cutter disc assembly. The cutter disc assembly comprises a cutter disc 1, a bearing assembly 2 and a cutter assembly 3. Figure 1 , Figure 3 and Figure 4As shown, when the blade disc assembly has a heating function, a heating element 19 and the like may be provided on the blade disc 1. In other embodiments, the blade disc 1 may not be provided with components such as a heating element 19, that is, the blade disc assembly does not have a heating function.

[0032] See also Figure 1 , Figure 3 and Figure 4 , the cutter disc 1 protrudes with a bearing seat 11 (usually, the center of the cutter disc 1 protrudes from the bearing seat 11). There is no limit on how the bearing seat 11 is protruded. For example, the bearing seat 11 can be formed by stamping, or by 3D printing and the like. In other embodiments, the bearing seat 11 can also be welded to the cutter disc 1. In any case, as long as the cutter disc 1 is provided with the bearing seat 11. The bearing seat 11 of the cutter disc assembly has an installation cavity 111. For example, the installation cavity 111 passes through the bearing seat 11. In some embodiments, the installation cavity 111 may not pass through the bearing seat, and the bearing assembly 2 can be installed. The bearing assembly 2 includes an inner liner 4, a bearing 21, a retaining ring 22, and the like. The bearing 21 is fastened in the inner liner 4. There is no limit on how it is fastened. In an embodiment of the present application, the inner liner 4 includes a bearing installation cavity 411. The bearing 21 can be fastened in the bearing installation cavity 411 by means of the retaining spring 22 or other fixing parts, thereby being fastened in the liner 4. The liner 4 includes an inserting portion 41. The inserting portion 41 is inserted into the installation cavity 111, and the inserting portion 41 is connected to the inner wall of the installation cavity 111 by a connecting structure. Figure 1 and Figure 2 and Figure 3 and Figure 4 By comparison, we can see the aforementioned connection relationship.

[0033] See also Figure 1 , Figure 3 and Figure 4 , the knife assembly 3 includes a knife shaft 31 and a blade 32. The knife shaft 31 is connected to the bearing 21 and passes through the installation cavity 111. The blade 32 is connected to the knife shaft 31 and is located above the knife disc 1. In an embodiment of the present application, the knife disc assembly 3 also includes a clutch 9 (here, an upper clutch). In some embodiments in which the drive is achieved by magnetic force, the knife disc assembly may also not include a clutch.

[0034] As described above, since the connection structure connects the liner 4 to the bearing seat 11, the bearing assembly can be firmly assembled to the bearing seat 11 through the connection structure, for example, the bearing assembly is not easy to fall off. Furthermore, the insertion portion 41 of the liner 4 is inserted into the installation cavity 111. In this way, after the bearing assembly 2 is located in the bearing installation cavity 411, the outer wall of the insertion portion 41 of the liner 4 contacts the inner wall of the installation cavity, ensuring the concentricity of the bearing assembly 2 and the knife shaft. For example, the bearing assembly 2 and the knife shaft 31 can be pressed into the installation cavity 111 as a whole, and the outer wall of the insertion portion 41 of the liner 4 contacts the inner wall of the installation cavity 111, avoiding the aforementioned overall eccentricity, thereby ensuring concentricity.

[0035] Based on the role played by the aforementioned insertion portion 41 and the mounting cavity 111, the shape of the insertion portion 41 and the shape of the mounting cavity 111 can be the same or different as long as the aforementioned purpose can be achieved.

[0036] See also Figure 3 Combined with Figure 2 , Figure 1 and Figure 4 , the connection structure includes a groove 412 and a protrusion 112. The inner wall of the installation cavity 111 is provided with a protrusion 112, and the outer wall of the insertion portion 41 of the liner 4 is provided with a groove 412. Of course, based on the principle of subsequent concave-convex matching, the bearing seat 11 can also be provided with a groove 412, and the liner 4 can be provided with a protrusion 112. Figure 2 , Figure 1 and Figure 4 , the protrusion 112 is located in the groove 412 .

[0037] As configured above, by the protrusion 112 being located in the groove 412 , a force acting along the axial direction of the knife shaft 31 is generated between the protrusion 112 and the groove 412 , thereby preventing the bearing assembly from falling off.

[0038] Based on the above mentioned functions of the protrusion 112 and the groove 412, the structures of the groove 412 and the protrusion 112 are not limited. A structure of the present application is described as follows.

[0039] See also Figure 3 Combined with Figure 4 The groove 412 is located on the outer wall of the inserting portion 41. The groove 412 is around the circumference of the cutter head assembly, that is, the groove 412 is a circle of grooves. The protrusions 112 are located on the inner wall of the mounting cavity 111. The protrusions 112 are distributed at intervals in the circumference of the cutter head assembly, for example, there are 2 to 6 protrusions 112.

[0040] In other embodiments, the groove 412 is located on the outer wall of the inserting portion 41. The protrusion 112 is located on the inner wall of the mounting cavity 111. The groove 412 and the protrusion 112 are both around the circumference of the cutter head assembly.

[0041] As described above, no matter the groove 412 surrounds the cutter disc assembly, the protrusions 112 are arranged at intervals, or the groove 412 and the protrusions 112 surround the cutter disc assembly. Because the groove 412 is a circle, the protrusion 112 can enter the groove 412 at any position in the circumferential direction. Therefore, the bearing assembly 2 is not only easier to assemble with the bearing seat 11 of the cutter disc 1, but also the bearing assembly 2 is not easy to fall off from the bearing seat 11 of the cutter disc 1.

[0042] In some embodiments, the lining 4 is a plastic part, a silicone part or a powder metallurgy part. Of course, the material of the lining 4 is not limited thereto.

[0043] As set up above, the lining 4 is a plastic part or a silicone part, and is inserted into the installation cavity 111 in combination with the insertion portion 41 of the lining 4. In this way, the lining 4 can play a buffering role, which can effectively reduce the movement of the bearing assembly 2 caused by the knife assembly 3 stirring food, thereby extending the life of the bearing assembly 2 and the life of the knife shaft 31, avoiding friction loss caused by vibration, and thus reducing the risk of water leakage.

[0044] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The bearing seat 11 and the cutter disc 1 are integrally formed.

[0045] As described above, since the bearing seat 11 is integrally formed with the cutter disc 1, welding between the bearing seat and the cutter disc 1 is avoided, and there is no welding point at the intersection of the bearing seat 11 and the main body 10 of the cutter disc 1 (such as Figure 1 , Figure 2 , Figure 3 and Figure 4 On the one hand, no welding is required, which can reduce costs. On the other hand, because no welding is required, there are no welding points, which can prevent rust at the welding points and prevent water leakage caused by welding points falling off. There will also be no water leakage due to loose threads like the threaded connection between the bearing seat and the cutter disc.

[0046] See also Figure 3 Combined with Figure 1 , Figure 2 and Figure 4The cutter head 1 includes a mounting portion 12 located at the side of the bearing seat 11 and opposite to the bearing seat 11. The liner 4 includes a fixing portion 42 located at the side of the inserting portion 41, and the fixing portion 42 is fixedly connected to the mounting portion 12.

[0047] As described above, after the bearing assembly 2 and the cutter shaft 31 are assembled as a whole, they are pressed into the installation cavity 111 as a whole, and then fixedly connected with the installation portion 12 by the fixing portion 42, the assembly of the cutter disc assembly is simple. In addition, since the fixing portion 42 is located on the side of the insertion portion 41, and the installation portion 12 is located on the side of the bearing seat 11, when the fixing portion 42 abuts against the installation portion 12, the liner 4 and other components cannot be pressed in, preventing the cutter disc 1 from being damaged. Moreover, the combination of the fixed connection and the connection structure further ensures that the bearing assembly 2 will not fall off the bearing seat 11.

[0048] In some embodiments, the cutter head assembly further comprises at least one of the following features:

[0049] a) The fixing portion 42 is welded, screwed or integrally formed with the mounting portion 12 to achieve the fixed connection; in this way, the liner 4 (bearing assembly 2) and the cutter head 1 (bearing seat 11) are conveniently assembled by welding, screwing or integrally forming. When the fixing portion 42 and the mounting portion 12 are integrally formed, that is, the liner 4 (bearing assembly 2) and the cutter head 1 (bearing seat 11) are integrally formed, the bearing 21 can also be assembled in the bearing mounting cavity 411 by means of the aforementioned retaining spring 22.

[0050] b) The fixing portion 42 surrounds the inserting portion 41; the mounting portion 12 surrounds the bearing seat 11; as configured above, the liner 4 (bearing assembly 2) and the cutter disc 1 (bearing seat 11) have more contact points, the cutter disc 1 and the liner 4 are firmly assembled, and the bearing assembly 2 is not easy to fall off.

[0051] c) The mounting portion 12 is a step. Figure 2 As shown, the mounting portion 12 is lower than the back side 110 of the cutter head 1 to form a step. As described above, since the mounting portion 12 is a step, it can play a positioning role and is more convenient for assembling the liner 4 and the cutter head 1.

[0052] See also Figure 3 Combined with Figure 1 , Figure 2 and Figure 4The liner 4 includes a bearing mounting cavity 411 for accommodating the bearing 21 and an accommodating cavity 413 connected to the bearing mounting cavity 411. The cutter head assembly includes a seal 5, and the seal 5 is located in the accommodating cavity 413, and is used to seal the top gap between the liner 4 and the bearing seat 11. For example, the seal 5 is pressed against the inner wall of the mounting cavity 111 and the inner wall of the accommodating cavity 413 to seal the gap. The structure of the seal 5 is not limited as long as it can achieve a sealing effect. In an embodiment of the present application, the seal 5 is an oil seal.

[0053] As configured as above, the seal 5 only needs to be placed in the accommodating cavity 413, and after the lining 4 and other components are pressed into the installation cavity 111, the seal 5 can be pressed tightly against the inner wall of the installation cavity 111 and the inner wall of the accommodating cavity 413. The installation of the seal 5 is simple, and the sealing effect is good because of the aforementioned pressing.

[0054] In a second aspect, the embodiments of the present application disclose a blending cup assembly, wherein the blending cup assembly comprises a blending cup and any of the aforementioned blade disc assemblies, wherein the blade disc 1 and the blending cup form a food processing cavity.

[0055] In a third aspect, the embodiment of the present application discloses a food processor. The food processor comprises a mixing cup, a driving device and any of the aforementioned blade disc assemblies. The driving device drives the blade assembly 3 to rotate in the mixing cup. There is no limit to how the blade assembly 3 is driven, and the blade assembly 3 can be driven by a clutch or by magnetic force.

[0056] The above description is only a preferred implementation mode of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
