Abstract
Description
Technical Field
[0001] The present application relates to the technical field of small household appliances, and in particular to a mixing blade assembly and a food processor. Background Art
[0002] Existing food processors generally consist of a mixing cup and a main unit. The mixing cup is usually made of high boron glass. The knife assembly is detachably arranged at the bottom of the mixing cup and mixes the ingredients by cooperating with the drive shaft. In this structure, there is a risk that the knife assembly will be lifted up by the ingredients and fall off the drive shaft during cooking. After the knife assembly falls out, it may hit the mixing cup and cause it to break, posing a safety hazard. Therefore, it is urgent to solve this problem. Summary of the invention
[0003] The purpose of the present application is to provide a stirring knife assembly and a food processor, which can effectively prevent the knife assembly from being lifted up by food materials, thereby improving the safety of the food processor during use.
[0004] The present application provides a stirring knife assembly, including a driving shaft and a knife assembly, wherein the knife assembly is detachably mounted on the driving shaft, and the knife assembly includes a sleeve mounted on the driving shaft and a blade fixed to the sleeve; wherein the driving shaft is provided with a stopper, and the stopper includes a fixing portion fixed to the driving shaft and a stopper protruding radially outward from the driving shaft, wherein the distance between the stopper and the axis of the driving shaft in a first state is less than or equal to the inner diameter of the sleeve; and the distance between the stopper and the axis of the driving shaft in a second state is greater than the inner diameter of the sleeve, so as to limit the knife assembly to the driving shaft. In the process of mounting the knife assembly on the driving shaft or removing the knife assembly from the driving shaft, the stopper is in the first state; and in the process of the food processor working, the stopper is in the second state.
[0005] As set up as above, since the knife assembly is detachably mounted on the drive shaft, the knife assembly can be removed for cleaning after the use of the food processor, so that the cleaning is more thorough; the knife assembly is limited to the drive shaft by the limit piece provided on the drive shaft, making the installation and disassembly of the knife assembly more convenient, and the knife assembly can be stuck during whipping cooking to prevent the knife assembly from being lifted up by the food and detached from the drive shaft, thus making the food processor safer during use.
[0006] In some embodiments, the drive shaft is provided with a mounting cavity penetrating the top end and a through hole communicating with the mounting cavity, the fixing portion is fixed in the mounting cavity by a fixing member, and the limiting portion extends the drive shaft outward through the through hole. The fixing member can stably and reliably fix the limiting member in the mounting cavity, and the structure is simple. The size of the limiting portion matches the aperture of the through hole, so that the limiting portion can extend the drive shaft from the through hole. In other embodiments, the limiting member can also be fixed in the mounting cavity by means of a snap, a screw or welding.
[0007] In some embodiments, the bottom wall of the installation cavity is provided with a slot, and the position-limiting member includes a clamping portion inserted into the slot. The clamping portion cooperates with the slot to limit the bottom end of the position-limiting member, so that the position-limiting member can be fixed in the installation cavity more stably and reliably. The shape and size of the slot match the shape and size of the clamping portion.
[0008] In some embodiments, the limiting member is elastic, and the limiting portion switches between the first state and the second state through elastic deformation. In the process of installing the knife assembly on the drive shaft or removing the knife assembly from the drive shaft, the limiting portion is squeezed by the sleeve and switches from the second state to the first state through elastic deformation; when the knife assembly is installed in place, the limiting portion switches from the first state to the second state through its own elastic deformation, and the limiting portion can limit the knife assembly to the drive shaft. In this way, the elastic deformation of the limiting portion makes the installation and disassembly of the knife assembly very convenient, and the knife assembly can be reliably limited to the drive shaft, effectively preventing the knife assembly from detaching from the drive shaft, and making it safer to use.
[0009] In some embodiments, the limiting portion is configured as a spherical surface.
[0010] As set up above, the spherical structure is symmetrical in all directions, so when subjected to external forces, the stress can be distributed relatively evenly across the entire spherical surface. This uniformity helps reduce areas of stress concentration, thereby improving the strength and durability of the structure. Since the sphere has the same curvature in all directions, it can deform elastically evenly in multiple directions. This multi-directional deformation capability enables the spherical structure to better adapt to external forces or pressures from different directions. Moreover, the spherical structure is relatively simple and easy to manufacture and process.
[0011] In some embodiments, the installation cavity includes a deformation cavity located below the fixing member, and the deformation cavity corresponds to the position of the limiting portion. By providing the deformation cavity, a deformation space is provided for the limiting portion to switch from the second state to the first state.
[0012] In some embodiments, the driving shaft includes two through holes arranged opposite to each other, the two limiting members are respectively arranged in the mounting cavity, and the limiting parts of the two limiting members respectively extend out of the driving shaft through the two through holes. In this way, by providing two limiting members, the limiting members can be more reliably limited.
[0013] In some embodiments, the stopper is stamped from a sheet. The production efficiency of the stopper can be improved, and a large number of stoppers can be quickly manufactured to meet the use requirements. In addition, the stamping process can ensure that the size and shape of the stopper have a high degree of accuracy and consistency, effectively utilize materials, and reduce waste. By cutting the material into an appropriate shape and stamping it, each piece of material can be utilized to the maximum extent, thereby reducing material costs. At the same time, the stopper stamped from the sheet usually has high strength and durability, and is easy to assemble and replace during maintenance or installation.
[0014] In some embodiments, the limiter is made of a thermally deformable material. For example, the material of the limiter can be a bimetallic strip or other materials. When the food processor is not working, or after work is completed, the limiter is not heated and is in the first state. At this time, the knife assembly can be installed on the drive shaft, or the knife assembly can be removed from the drive shaft. When the food processor starts to work, the temperature of the limiter rises and the limiter is deformed, and switches from the first state to the second state. At this time, the limiter can limit the knife assembly to the drive shaft, reliably limit the knife assembly to the drive shaft, effectively prevent the knife assembly from detaching from the drive shaft, and make it safer to use.

[0016] A main unit; a blending cup assembly installed on the main unit, the blending cup assembly comprising a blending cup and a base fixed to the bottom of the blending cup, a handle assembly being provided on the side of the blending cup; the blending blade assembly being provided at the bottom of the blending cup, wherein the drive shaft passes through the base; and a cup cover assembly being provided on the blending cup assembly.

[0028] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.
[0029] See also Figure 2 The embodiment of the present application discloses a stirring knife assembly 11, comprising a driving shaft 111 and a knife assembly 112, wherein the knife assembly 112 is detachably mounted on the driving shaft 111, and the knife assembly 112 comprises a sleeve 1121 sleeved on the driving shaft 111 and a blade 1122 fixed to the sleeve 1121; wherein the driving shaft 111 is provided with a limiting member 113, wherein the limiting member 113 comprises a fixing portion 1132 fixed to the driving shaft 111 and a limiting portion 1131 radially protruding outward from the driving shaft 111, wherein in a first state, the distance between the limiting portion 1131 and the axis of the driving shaft 111 is less than or equal to the inner diameter of the sleeve 1121; in a second state, the distance between the limiting portion 1131 and the axis of the driving shaft 111 is greater than the inner diameter of the sleeve 1121, so as to limit the knife assembly to the driving shaft 111. During the process of installing the knife assembly 112 on the driving shaft 111 or removing the knife assembly 112 from the driving shaft 111, the limiting portion 1131 is in the first state; during the operation of the food processor 100, the limiting portion 1131 is in the second state.
[0030] Since the knife assembly 112 is detachably mounted on the drive shaft 111, the knife assembly 112 can be removed for cleaning after the use of the food processor 100, so that the cleaning is more thorough; the knife assembly 112 is limited on the drive shaft 111 by the limiter 113 provided on the drive shaft 111, making the installation and removal of the knife assembly 112 more convenient, and the knife assembly 112 can be stuck during whipping cooking to prevent the knife assembly 112 from being lifted up by the food and detached from the drive shaft 111, thus making the food processor 100 safer during use.
[0031] See also Figure 3 and Figure 7 In some embodiments, the drive shaft 111 is provided with a mounting cavity 1112 that passes through the top and a through hole 1113 that communicates with the mounting cavity 1112, the fixing portion 1132 is fixed in the mounting cavity 1112 by a fixing member 114, and the limiting portion 1131 extends outward from the drive shaft 111 through the through hole 1113. In other embodiments, the limiting member 113 can also be fixed in the mounting cavity 1112 by means of a snap, a screw or welding. The limiting member 113 can be stably and reliably fixed in the mounting cavity 1112 by the fixing member 114, and the structure is simple. The size of the limiting portion 1131 matches the aperture of the through hole 1113, so that the limiting portion 1131 can extend the drive shaft 111 from the through hole 1113.
[0032] See also Figure 8 and Fig. 9 In some embodiments, the bottom wall of the installation cavity 1112 is provided with a slot 1111, and the stopper 113 includes a clamping portion 1133 inserted into the slot 1111. The clamping portion 1133 cooperates with the slot 1111 to limit the bottom end of the stopper 113, so that the stopper 113 can be fixed in the installation cavity 1112 more stably and reliably. The shape and size of the slot 1111 match the shape and size of the clamping portion 1133.
[0033] See also Figure 4In some embodiments, the stopper 113 is elastic, and the stopper 1131 switches between the first state and the second state through elastic deformation. In the process of installing the knife assembly 112 on the drive shaft 111 or removing the knife assembly 112 from the drive shaft 111, the stopper 1131 is squeezed by the sleeve 1121 and switches from the second state to the first state through elastic deformation; when the knife assembly 112 is installed in place, the stopper 1131 switches from the first state to the second state through its own elastic deformation, and the stopper 1131 can limit the knife assembly 112 to the drive shaft 111. In this way, the elastic deformation of the stopper 1131 makes it very convenient to install and remove the knife assembly 112, and the knife assembly 112 can be reliably limited on the drive shaft 111, effectively preventing the knife assembly 112 from being separated from the drive shaft 111, and making it safer to use.
[0034] See also Figure 4 and Figure 5 In some embodiments, the limiting portion 1131 is configured as a spherical surface.
[0035] As set up above, the spherical structure is symmetrical in all directions, so when subjected to external forces, the stress can be distributed relatively evenly across the entire spherical surface. This uniformity helps reduce areas of stress concentration, thereby improving the strength and durability of the structure. Since the sphere has the same curvature in all directions, it can deform elastically evenly in multiple directions. This multi-directional deformation capability enables the spherical structure to better adapt to external forces or pressures from different directions. Moreover, the spherical structure is relatively simple and easy to manufacture and process.
[0036] See also Figure 6 In some embodiments, the installation cavity 1112 includes a deformation cavity 1114 located below the fixing member 114, and the deformation cavity 1114 corresponds to the position of the limiting portion 1131. By providing the deformation cavity 1114, a deformation space is provided for the limiting portion 1131 to switch from the second state to the first state.
[0037] See also Figure 5 and Figure 6 In some embodiments, the driving shaft 111 includes two through holes 1113 that are oppositely disposed, the two limiting members 113 are respectively disposed in the mounting cavity 1112, and the limiting portions 1131 of the two limiting members 113 extend out of the driving shaft 111 through the two through holes 1113. In this way, by providing two limiting members 113, the limiting member 113 can be more reliably limited.
[0038] See also Figure 4 In some embodiments, the limiting member 113 is formed by stamping a sheet of material.
[0039] As described above, the production efficiency of the stopper 113 can be improved, and a large number of stoppers 113 can be quickly manufactured to meet the use requirements. In addition, the stamping process can ensure that the size and shape of the stopper 113 have a high degree of precision and consistency, effectively utilize materials, and reduce waste. By cutting the material into an appropriate shape and stamping it, each piece of material can be utilized to the maximum extent, thereby reducing material costs. At the same time, the stopper 113 stamped from the sheet material usually has high strength and durability, and is easy to assemble and replace during maintenance or installation.
[0040] In some embodiments, the stopper 113 is made of a thermally deformable material. For example, the stopper 113 may be made of a bimetallic sheet, but is not limited thereto.
[0041] As described above, when the food processor 100 is not working, or after the work is finished, the stopper 113 is not heated and is in the first state. At this time, the knife assembly 112 can be installed on the drive shaft 111, or the knife assembly 112 can be removed from the drive shaft 111. When the food processor 100 starts to work, the stopper 113 increases in temperature and deforms, and switches from the first state to the second state. At this time, the stopper 1131 can reliably limit the knife assembly 112 on the drive shaft 111, effectively preventing the knife assembly 112 from detaching from the drive shaft 111, and making it safer to use.
[0042] See also Figure 1 The embodiment of the present application discloses a food processor, wherein the food processor 100 includes: a main unit 3, a blending cup assembly 1 and a cup cover assembly 2.
[0043] The blending cup assembly 1 is installed on the main machine 3, and the blending cup assembly 1 includes a blending cup 14 and a base 12 fixed to the bottom of the blending cup, and a handle assembly 13 is provided on the side of the blending cup 14; the blending blade assembly 11 is provided at the bottom of the blending cup 14, wherein the driving shaft 111 passes through the base 12. The cup cover assembly 2 is provided on the blending cup assembly 1.

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.
