DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0028] The first aspect of the embodiments of the present application provides a whipping assembly, which is a key component in a food processor, a blender or other food processing equipment, and its main function is to mix or stir food materials into the desired texture through rotation, cutting or stirring, etc.

[0029] Please refer to Figures 1-2 , the whipping assembly 10 includes a rotating shaft 11 and a whipping element 12.

[0030] Specifically, the rotating shaft 11 includes a driving section 111, the driving section 111 includes a plurality of edges 1111 extending in the length direction of the rotating shaft 11, and the plurality of edges 1111 gradually deflects along the circumference of the driving section 111; that is, the driving section 111 is provided with a plurality of edges 1111 deflecting along the circumference of the driving section 111, and the number of the edges 1111 is not specifically limited. It should be noted that when the whipping assembly 10 is applied to a food processor, the length direction of the rotating shaft 11 refers to the up-down direction of the food processor; when the whipping assembly 10 is applied to a noodle machine, the length direction of the rotating shaft 11 refers to the horizontal direction.

[0031] The rotating shaft 11 further comprises a connecting section 113 fixedly connected with the driving section 111; the food processing device generally comprises a motor, the motor has a motor shaft 41, the connecting section 113 is installed in the motor shaft 41 and is in driving connection with the motor shaft 41, so that when the motor works, the rotating shaft 11 is responsible for transmitting the power of the motor rotation to the whipping member 12, thereby driving the whipping member 12 to rotate, and then realizing the whipping and crushing of food. The connecting section 113 and the motor shaft 41 can be connected by threads or a shaft coupling, and the embodiments of the application do not make specific limitations.

[0032] Please refer to Figures 3-4 The whipping member 12 comprises a frame body 121 and a whipping part 122, the frame body 121 is sleeved on the rotating shaft 11, and the whipping part 122 is connected to the frame body 121. It can be understood that the frame body 121 is detachably connected with the rotating shaft 11, and when it is necessary to install the rotating shaft 11 on the whipping member 12, the frame body 121 can be sleeved on the rotating shaft 11 to complete the assembly between the frame body 121 and the rotating shaft 11; the frame body 121 acts as a support structure for the whipping part 122 and plays a role of fixing and carrying the whipping part 122, therefore, the frame body 121 is designed to be strong and durable to ensure that it can remain stable during whipping and will not shake or deform due to strong stirring action. Common materials used to make the frame body 121 include high-strength, corrosion-resistant materials such as stainless steel and alloy steel, and the embodiments of the application do not make specific limitations.

[0033] The whipping part 122 can be connected to the frame body 121 by welding, riveting, pressure bonding or the like to achieve fixed connection between the whipping part 122 and the frame body 121. In addition, since the whipping assembly 10 can be applied to different food processing devices, the shape of the whipping part 122 can be various; that is, the whipping part 122 can be a blade, a stirring rod, a dispersion disc or the like. Exemplarily, when the whipping assembly 10 is applied to the food processor 1, the whipping part 122 can be a blade. According to the properties of the food to be stirred, the purpose of stirring and the like, the above-mentioned blade can be an inclined blade, a curved blade, a spiral blade or the like, and the embodiments of the application do not make specific limitations.

[0034] Furthermore, since the whipping member 12 is detachably connected with the rotating shaft 11, when the whipping member 12 needs to be cleaned after use, the user can rotate the whipping member 12 to detach it and clean it, so that the whipping member 12 no longer has the problem of dead angle that cannot be cleaned, thereby effectively avoiding the problem of bacterial growth and odor generation of the whipping member 12.

[0035] However, in the related art, the fitting gap between the beating element 12 and the rotating shaft 11 is small, so that accurate alignment is required during the installation of the beating element 12 and the rotating shaft 11, which leads to the difficulty in the installation alignment of the beating element 12 and the rotating shaft 11.

[0036] Please refer to Figures 4-6 In order to solve the above problems, further, the frame body 121 has a driving hole 123 accommodating the rotating shaft 11, and the end of the driving hole 123 for inserting the rotating shaft 11 includes a guide hole section 1231. It can be understood that the rotating shaft 11 can be inserted into the driving hole 123 from the guide hole section 1231, so that part of the rotating shaft 11 is accommodated in the driving hole 123; wherein the inner wall of the guide hole section 1231 includes a plurality of inclined planes 12311 connected in sequence in the circumferential direction, and the caliber of the guide hole section 1231 is arranged to decrease in the direction of insertion of the rotating shaft 11. It can be understood that, during the insertion of the rotating shaft 11 into the driving hole 123, because the inner wall of the guide hole section 1231 is arranged as the inclined plane 12311, and the caliber of the guide hole section 1231 is arranged to decrease in the direction of insertion of the rotating shaft 11, so that in the direction of insertion of the rotating shaft 11, the caliber of the guide hole section 1231 is largest when the rotating shaft 11 is just inserted into the driving hole 123, and the caliber of the guide hole section 1231 decreases as the rotating shaft 11 is inserted further into the driving hole 123, so that the insertion of the rotating shaft 11 can be guided, so as to facilitate the assembly of the rotating shaft 11 into the driving hole 123. At the same time, the caliber of the guide hole section 1231 is arranged to decrease in the direction of insertion of the rotating shaft 11, so that the edge 1111 can be rotationally fitted with the inclined plane 12311, so that during the operation of the motor, the adjacent inclined planes 12311 form meshing grooves, and the edge 1111 of the rotating shaft 11 is protrudingly arranged and engaged with the meshing grooves as the rotating shaft 11 rotates, so that the edge 1111 and the inclined plane 12311 have a driving effect, so as to facilitate the rotation of the beating element 12; in addition, the edge 1111 and the inclined plane 12311 can also function as a limiting effect, so as to prevent the beating element 12 from being separated from the rotating shaft 11 during rotation, thereby improving the safety of the beating assembly 10 in use.

[0037] It should be noted that the number of inclined planes 12311 and the number of edges 1111 are not specifically limited in the embodiments of the present application. Exemplarily, the number of inclined planes 12311 needs to be greater than 3, and the number of edges 1111 also needs to be greater than 3, so that on the one hand the installation of the rotating shaft 11 is facilitated, and on the other hand the stability of the fitting between the edge 1111 and the inclined plane 12311 is improved.

[0038] The inner wall of the guide hole section 1231 comprises a plurality of inclined planes 12311 connected in sequence in the circumferential direction, and the caliber of the guide hole section 1231 decreases in the direction of insertion of the rotating shaft 11. In the direction of insertion of the rotating shaft 11, the caliber of the guide hole section 1231 is the largest when the rotating shaft 11 is just inserted into the driving hole 123, and the caliber of the guide hole section 1231 decreases as the rotating shaft 11 is inserted further into the driving hole 123. Thus, the insertion of the rotating shaft 11 is guided, facilitating the disassembly and assembly of the beating element 12 in the beating assembly 10. In addition, the caliber of the guide hole section 1231 decreases in the direction of insertion of the rotating shaft 11, so that the edge 1111 can rotate with the inclined plane 12311. During the operation of the motor, the edge 1111 and the inclined plane 12311 drive each other, facilitating the rotation of the beating element 12, thereby improving the working efficiency of the beating assembly 10.

[0039] Referring to Figures 3-4 In some embodiments, the frame body 121 can comprise a first part 1211 and a second part 1212 forming an integrated structure.

[0040] Specifically, the first part 1211 and the second part 1212 can be formed into an integrated structure by welding or the like, or by pressure casting in a mold cavity, or by injection molding, which is not limited in the present application. Furthermore, the driving hole 123 penetrates the end surface of the second part 1212 and extends into the first part 1211. Thus, when the rotating shaft 11 is inserted into the driving hole 123, part of the rotating shaft 11 can extend into the first part 1211 through the end surface of the second part 1212, and the other part of the rotating shaft 11 extends out of the end surface of the second part 1212. Thus, the other part of the rotating shaft 11 can be connected in transmission with the motor shaft 41.

[0041] Further, the connection between the first part 1211 and the second part 1212 is in a stepped structure 1213; that is, the diameter of the connection between the first part 1211 and the second part 1212 is larger than the diameter of the second part 1212, so that the connection between the first part 1211 and the second part 1212 is in the stepped structure 1213. The beating part 122 includes a blade, when the blade is assembled with the frame 121, the blade can be fixed to the stepped structure 1213 by riveting, and the blade abuts against the first part 1211 and the second part 1212. It can be understood that, since the diameter of the connection between the first part 1211 and the second part 1212 is larger than the diameter of the second part 1212, the stepped structure 1213 includes a first surface perpendicular to the axis of the driving hole 123, and a second surface parallel to the axis of the driving hole 123, wherein the first surface is formed by the part of the end surface of the first part 1211, and the second surface is the outer wall surface of the second part 1212, and when the blade is fixed to the stepped structure 1213 by riveting, the blade can abut against the part of the end surface of the first part 1211, and the blade also abuts against the outer wall surface of the second part 1212, so that the stability of the installation between the beating part 122 and the frame 121 is improved.

[0042] Further, in some embodiments, the middle part of the first part 1211 is convexly arranged towards the center line of the driving hole 123, so that in the direction of the insertion of the rotating shaft 11, the first part 1211 has a change trend of gradually reducing in the middle part and gradually increasing at both ends, so that on the one hand, the end surface of the first part 1211 close to the second part 1212 forms the stepped structure 1213 with the second part 1212, so as to facilitate the installation of the blade at the stepped structure 1213; on the other hand, when the user needs to disassemble or assemble the beating part 122 and the rotating shaft 11, the middle part of the first part 1211 is reduced relative to the both ends of the first part 1211, so as to facilitate the user to hold.

[0043] Please refer to Figure 4In some embodiments, an angle a is formed between each inclined plane 12311 and a reference plane perpendicular to the axis of the driving hole 123, and the angle a is greater than or equal to 80 degrees and less than or equal to 87 degrees; that is, the angle a can be 80 degrees, 82 degrees, 84 degrees, 86 degrees, 87 degrees. In this way, on the one hand, the shaft 11 can be easily inserted into the driving hole 123; on the other hand, the friction between the inclined plane 12311 and the edge 1111 can be reduced, and the stability of the connection between the shaft 11 and the beating element 12 can be ensured. If the angle a is less than 80 degrees, at this time, the angle a is small, and the shaft 11 can be difficult to insert into the driving hole 123, which can cause the shaft 11 to be difficult to assemble. If the angle a is greater than 87 degrees, at this time, the angle a is large, and the gap between the edge 1111 and the inclined plane 12311 is large, which is not conducive to the stability of the connection between the shaft 11 and the beating element 12. In the process of high-speed rotation of the beating assembly 10, the beating element 12 can easily separate from the shaft 11, which can reduce the safety of the beating assembly 10 in use.

[0044] Please continue to refer to Figure 4 In some embodiments, the length L1 of the guide hole section 1231 in the direction of insertion of the shaft 11 is greater than or equal to 2 mm and less than or equal to 8 mm; that is, the length L1 of the guide hole section 1231 can be 2 mm, 4 mm, 6 mm, 8 mm, etc. In this way, the stability of the connection between the inner wall of the guide hole section 1231 and the shaft 11 can be improved, and the friction and wear between the inner wall of the guide hole section 1231 and the outer wall surface of the shaft 11 can be reduced. If the length L1 of the guide hole section 1231 is less than 2 mm, at this time, the length of the inclined plane 12311 is small, and when the shaft 11 and the beating element 12 are matched, the matching part between the inclined plane 12311 and the edge 1111 is small, which can reduce the stability of the connection between the inclined plane 12311 and the edge 1111. If the length L1 of the guide hole section 1231 is greater than 8 mm, at this time, the length of the guide hole section 1231 is long, which can increase the contact area between the inner wall of the guide hole section 1231 and the outer wall surface of the shaft 11, thereby increasing the friction and wear, and shortening the service life of the shaft 11 and the guide hole section 1231.

[0045] In some embodiments, the first gap between the hole wall at the minimum diameter of the front end of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 and the outer wall surface of the rotating shaft 11 is greater than 0 mm and less than or equal to 0.3 mm; that is, the first gap can be 0.1 mm, 0.2 mm, 0.3 mm, etc. In this way, direct contact between the rotating shaft 11 and the inner wall of the front end of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 during rotation of the rotating shaft 11 can be reduced, thereby reducing friction and wear, and avoiding vibration and noise of the whipping assembly 10 during rotation of the whipping assembly 10. If the gap is less than 0 mm, at this time, interference fit exists between the hole wall at the minimum diameter of the front end of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 and the outer wall surface of the rotating shaft 11. In this way, rotation between the inner wall of the guide hole segment 1231 and the edge 1111 is difficult, so that the whipping assembly 10 is prone to jamming during rotation of the whipping assembly 10, which is not convenient for normal use of the whipping assembly 10. If the gap is greater than 0.3 mm, at this time, the gap between the hole wall at the minimum diameter of the front end of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 and the outer wall surface of the rotating shaft 11 is too large, which easily causes the rotating shaft 11 to shake in the guide hole segment 1231 or unstable connection between the rotating shaft 11 and the inner wall of the guide hole segment 1231, thereby causing vibration and noise of the whipping assembly 10 during rotation of the whipping assembly 10, and existing safety problems in use.

[0046] Further, the second gap between the hole wall at the minimum diameter of the end of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 and the outer wall surface of the rotating shaft 11 is greater than 0 mm and less than or equal to 0.5 mm; that is, the second gap can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc. In this way, direct contact between the rotating shaft 11 and the inner wall of the end of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 during rotation of the rotating shaft 11 can be reduced, thereby reducing friction and wear, and avoiding vibration and noise of the whipping assembly 10 during rotation of the whipping assembly 10. If the gap is less than 0 mm, at this time, interference fit exists between the hole wall at the minimum diameter of the end of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 and the outer wall surface of the rotating shaft 11. In this way, rotation between the inner wall of the guide hole segment 1231 and the edge 1111 is difficult, so that the whipping assembly 10 is prone to jamming during rotation of the whipping assembly 10, which is not convenient for normal use of the whipping assembly 10. If the gap is greater than 0.3 mm, at this time, the gap between the hole wall at the minimum diameter of the end of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 and the outer wall surface of the rotating shaft 11 is too large, which easily causes the rotating shaft 11 to shake in the guide hole segment 1231 or unstable connection between the rotating shaft 11 and the inner wall of the guide hole segment 1231, thereby causing vibration and noise of the whipping assembly 10 during rotation of the whipping assembly 10, and existing safety problems in use.

[0047] Please refer to Figures 7-8In some embodiments, the driving hole 123 further comprises a main hole section 1232 and a limiting hole section 1233.

[0048] Specifically, one end of the main hole section 1232 is connected with the guide hole section 1231; that is, when the whipping assembly 10 is applied to the food processor 1, the main hole section 1232 is located above the guide hole section 1231, and the inner diameter of the main hole section 1232 is greater than that of the guide hole section 1231, so that the rotating shaft 11 can be inserted into the main hole section 1232 after passing through the guide hole section 1231. The other end of the main hole section 1232 is connected with the limiting hole section 1233; that is, the main hole section 1232 is located between the limiting hole section 1233 and the guide hole section 1231.

[0049] Please refer to Figure 2 and Figure 7 Further, the driving section 111 comprises a main section 1112 and a limiting section 1113. The main section 1112 is fixedly connected with the limiting section 1113, and the edge 1111 is arranged on the main section 1112 in the direction of insertion of the rotating shaft 11, and the limiting section 1113 is located at the front end of the driving hole 123, so that the edge 1111 of the main section 1112 can be matched with the inclined plane 12311. In the present embodiment, the limiting section 1113 is tightly matched with the limiting hole section 1233, so that after the rotating shaft 11 is inserted into the driving hole 123, the limiting hole section 1233 is tightly matched with the limiting section 1113, and the inclined plane 12311 is also matched with the edge 1111, so that the stability of the rotating shaft 11 installed in the driving hole 123 can be improved to avoid the phenomenon that the whipping assembly 10 is separated during rotation.

[0050] Please refer to Figure 7 Further, the front end of the limiting hole section 1233 has a through hole 1234 which is communicated with the driving hole 123, so that when the rotating shaft 11 is inserted into the driving hole 123, the air in the driving hole 123 can be exhausted through the through hole 1234 due to the existence of the through hole 1234, so as to facilitate the insertion of the rotating shaft 11 into the driving hole 123.

[0051] Please refer to Figures 7-8Further, in some embodiments, the limiting section 1113 is provided with a groove; the rotating shaft 11 further comprises a sealing ring 112, the sealing ring 112 is annularly arranged in the groove, and the sealing ring 112 is in interference fit with the limiting hole section 1233. It can be understood that, when the food after being stirred needs to be poured out after the food processing equipment stops working, the sealing ring 112 can act on the inner wall of the limiting hole section 1233 to block the beating member 12; that is, the frame body 121 can be fixed on the rotating shaft 11 so that the frame body 121 will not be separated from the rotating shaft 11, thereby avoiding the situation that the beating assembly 10 is also poured out at the same time when the food after being stirred is poured out, so that the safety performance of the beating assembly 10 is improved. When the beating member 12 needs to be taken off from the rotating shaft 11, the user needs to exert a force on the beating member 12 away from the rotating shaft 11 when the driving hole 123 passes through the sealing ring 112, so that the beating member 12 is taken off from the rotating shaft 11.

[0052] In addition, since the sealing ring 112 is in interference fit with the limiting hole section 1233, the hole diameter of the limiting hole section 1233 is greater than the diameter of the limiting section 1113, so that the sealing ring 112 can avoid being subjected to excessive extrusion force from the inner wall of the limiting hole section 1233, thereby making the sealing ring 112 have good wear resistance to prolong the service life of the sealing ring 112.
