DETAILED DESCRIPTION

[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0027] 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.

[0028] Please refer to Figures 1-2The beating assembly 10 comprises a rotating shaft 11 and a beating element 12.

[0029] Specifically, the rotating shaft 11 comprises a driving section 111, which comprises a plurality of edges 1111 extending in the length direction of the rotating shaft 11 and gradually deflecting 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 beating assembly 10 is applied to the food processor, the length direction of the rotating shaft 11 refers to the up-down direction of the food processor 1; when the beating assembly 10 is applied to the noodle machine, the length direction of the rotating shaft 11 refers to the horizontal direction.

[0030] Please refer to Figure 1 and Figure 3 The rotating shaft 11 further comprises a connecting section 113 fixedly connected with the driving section 111; the food processing equipment generally comprises a motor, which has a motor shaft 41 inside, the connecting section 113 is installed in the motor shaft 41 and in transmission 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 beating element 12, thereby driving the beating element 12 to rotate, and further realizing the beating and crushing of food. The connecting section 113 and the motor shaft 41 can be connected through threads or through a shaft coupling, which is not specifically limited in the embodiment of the application.

[0031] Please continue to refer to Figure 1 and Figure 3 The beating element 12 comprises a frame 121 and a beating part 122, the frame 121 is sleeved on the rotating shaft 11, and the beating part 122 is connected to the frame 121. It can be understood that the frame 121 and the rotating shaft 11 are detachably connected, and when it is necessary to install the rotating shaft 11 on the beating element 12, the frame 121 can be sleeved on the rotating shaft 11 to complete the assembly between the frame 121 and the rotating shaft 11; the frame 121 acts as a support structure for the beating part 122, and plays a role of fixing and carrying the beating part 122, therefore, the frame 121 is designed to be strong and durable to ensure that it can remain stable during the beating process and will not shake or deform due to strong beating action. Common materials used to make the frame 121 include high-strength and corrosion-resistant materials such as stainless steel and alloy steel, which are not specifically limited in the embodiment of the application.

[0032] The beating part 122 can be connected to the frame body 121 by welding, riveting, crimping or the like, so as to be fixedly connected between the beating part 122 and the frame body 121. In addition, since the beating assembly 10 can be applied to different food processing equipment, the shape of the beating part 122 can be various; that is, the beating part 122 can be a blade, a stirring rod, a dispersing disc or the like. Exemplarily, when the beating assembly 10 is applied to the food processor 1, the beating part 122 can be provided with a blade. According to the properties of the food to be stirred, the stirring purpose or the like, the blade can be an inclined blade, a curved blade, a spiral blade or the like, which is not limited in the embodiment of the application.

[0033] Furthermore, since the beating part 12 and the rotating shaft 11 are detachably connected, when the beating part 12 needs to be cleaned after use, the user can rotate the beating part 12 to detach the beating part 12 and clean the beating part 12, so that the problem of dead angle of the beating part 12 cannot be cleaned is avoided, thereby effectively avoiding the problem of bacteria breeding and odor generation of the beating part 12.

[0034] However, in the related art, the fitting gap between the beating part 12 and the rotating shaft 11 is small, so that the beating part 12 and the rotating shaft 11 need to be accurately aligned during installation, which leads to difficulty in installation and alignment of the beating part 12 and the rotating shaft 11.

[0035] Please refer to Figures 4-5, in order to solve the above problems, further, the frame body 121 has a driving hole 123 containing the rotating shaft 11, the driving hole 123 includes a guide hole section 1231 at the end of the rotating shaft 11 inserted. 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 contained in the driving hole 123; wherein the inner wall of the guide hole section 1231 includes a plurality of matching arc surfaces 12311 connected in sequence along the circumference, the number of matching arc surfaces 12311 matches the number of edges 1111, and the hole diameter of the guide hole section 1231 is configured to be reduced in the direction of the rotating shaft 11 insertion. It can be understood that when the rotating shaft 11 needs to be assembled into the driving hole 123, because the number of matching arc surfaces 12311 matches the number of edges 1111, the matching arc surfaces 12311 and the edges 1111 can be matched with each other to guide the installation of the rotating shaft 11, thereby facilitating the assembly of the rotating shaft 11 into the driving hole 123. At the same time, in the working process of the motor, the rotating shaft 11 is responsible for transmitting the power of the motor rotation to the whipping element 12, at this time, the adjacent matching arc surfaces 12311 will form a meshing groove, and the edges 1111 of the rotating shaft 11 will be protruding, and with the rotation of the rotating shaft 11, the edges 1111 will engage with the meshing groove, so that the edges 1111 will be drivingly connected with the matching arc surfaces 12311, so that the matching arc surfaces 12311 and the edges 1111 play a driving role, thereby facilitating the rotation of the whipping element 12. When the rotating shaft 11 needs to be separated from the driving hole 123, it can be achieved by pushing the whipping element 12 away from the rotating shaft 11.

[0036] It should be noted that the number of matching arc surfaces 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 cooperation between the edges 1111 and the matching arc surfaces 12311 is improved.

[0037] The embodiment of the application sets the guide hole section 1231 at the end of the driving hole 123 for the rotating shaft 11 insertion, and the inner wall of the guide hole section 1231 includes a plurality of matching arc surfaces 12311 connected in sequence along the circumference, and the number of matching arc surfaces 12311 matches the number of edges 1111, so that during the assembly of the rotating shaft 11 into the driving hole 123, the matching arc surfaces 12311 can cooperate with the edges 1111 to guide the installation of the rotating shaft 11, thereby facilitating the disassembly and assembly of the whipping element 12 in the whipping assembly 10.

[0038] Please continue to see Figures 4-5In some embodiments, the middle portion of the matching arc surface 12311 is convexly arranged towards the center line of the driving hole 123; that is, the middle portion of the matching arc surface 12311 is closer to the center line of the driving hole 123 than the two ends of the matching arc surface 12311, so that the hole diameter of the guide hole section 1231 has a trend of decreasing in the middle and increasing at the two ends in the direction of insertion of the rotating shaft 11; in this way, the middle portion of the matching arc surface 12311 can cooperate with the edge 1111 to drive the rotation between the rotating shaft 11 and the beating element 12, and to avoid the beating element 12 from being separated from the rotating shaft 11 during high-speed rotation. During the insertion of the rotating shaft 11 into the driving hole 123, since the guide hole section 1231 is located at the end of the driving hole 123 for the insertion of the rotating shaft 11, when the rotating shaft 11 needs to be inserted into the driving hole 123, the rotating shaft 11 needs to pass through the guide hole section 1231. The present application has a trend of decreasing in the middle and increasing at the two ends of the hole diameter of the guide hole section 1231, so that, on the one hand, the rotating shaft 11 can be easily inserted into the driving hole 123, thereby guiding the assembly between the beating element 12 and the rotating shaft 11; on the other hand, when the rotating shaft 11 is completely inserted into the driving hole 123, the matching arc surface 12311 of the middle portion of the guide hole section 1231 can cooperate with the edge 1111 of the driving section 111 to prevent the beating element 12 from being separated from the rotating shaft 11.

[0039] Please refer to Figure 4 and Figure 6 Further, in some embodiments, the extension direction of the tangent line tangent to the middle portion of the matching arc surface 12311 in the direction of insertion of the rotating shaft 11 is parallel to the extension direction of the center line of the driving hole 123, so that, during the insertion and rotation of the rotating shaft 11 into the driving hole 123, the friction and resistance caused by the angle deviation or inconsistent direction between the matching arc surface 12311 and the edge 1111 can be reduced, thereby reducing the vibration and noise of the beating assembly 10 during rotation, improving the stability of the rotation of the beating assembly 10, and more easily achieving the accurate alignment between the rotating shaft 11 and the driving hole 123, thereby improving the assembly accuracy and reliability. At the same time, the meshing groove can be arranged at the middle portion of the matching arc surface 12311, so that the stress on the matching arc surface 12311 can be dispersed to the two ends of the guide hole section 1231 to reduce the wear of the matching arc surface 12311.

[0040] In some embodiments, the gap between the outer wall surface of the rotating shaft 11 and the minimum aperture of the guide hole segment 1231 is greater than 0 mm and less than or equal to 1 mm, that is, the gap can be 0.1 mm, 0.3 mm, 0.6 mm, 0.9 mm, 1 mm, etc. In this way, the direct contact between the rotating shaft 11 and the guide hole segment 1231 during rotation can be reduced to reduce friction and wear, thereby avoiding vibration and noise of the whipping assembly 10 during rotation. If the gap is less than 0 mm, that is, the minimum aperture of the guide hole segment 1231 and the outer wall surface of the rotating shaft 11 are in interference fit, which makes it difficult for the inner wall of the guide hole segment 1231 to rotate with the edge 1111, so that the whipping assembly 10 is prone to jamming during rotation, which is not convenient for normal use of the whipping assembly 10. If the gap is greater than 1 mm, the gap between the minimum aperture of the guide hole segment 1231 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 the inner wall of the guide hole segment 1231 to be unstable, resulting in vibration and noise of the whipping assembly 10 during rotation, and safety problems during use.

[0041] Please refer to Figure 4 In some embodiments, the length L1 of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 is greater than or equal to 2 mm and less than or equal to 10 mm, that is, the length L1 of the guide hole segment 1231 can be 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, etc. In this way, the stability of the connection between the inner wall of the guide hole segment 1231 and the rotating shaft 11 is improved, and the friction and wear between the inner wall of the guide hole segment 1231 and the outer wall surface of the rotating shaft 11 are reduced. If the length L1 of the guide hole segment 1231 is less than 2 mm, the length of the matching arc surface 12311 is small, and the matching surface between the matching arc surface 12311 and the edge 1111 is small when the rotating shaft 11 and the whipping element 12 are matched, which reduces the stability of the connection between the matching arc surface 12311 and the edge 1111. If the length L1 of the guide hole segment 1231 is greater than 10 mm, the length of the guide hole segment 1231 is long, which increases the contact area between the inner wall of the guide hole segment 1231 and the outer wall surface of the rotating shaft 11, thereby increasing the friction and wear, and shortening the service life of the rotating shaft 11 and the guide hole segment 1231.

[0042] In other embodiments, the gap between the minimum aperture of the guide hole segment 1231 and the outer wall surface of the rotating shaft 11 is greater than 0 mm and less than or equal to 1 mm, and the length L1 of the guide hole segment 1231 in the direction of insertion of the rotating shaft 11 is greater than or equal to 2 mm and less than or equal to 10 mm, and the effects are the same as above. The embodiments of the present application will not be repeated here.

[0043] Please refer toFigure 5 In some embodiments, the matching arc surface 12311 is a part of a circular arc surface, the radius of the matching arc surface 12311 is greater than or equal to 3 mm and less than or equal to 10 mm; that is, the radius of the matching arc surface 12311 can be 3 mm, 6 mm, 9 mm, 10 mm, etc. In this way, on the one hand, the friction between the matching arc surface 12311 and the edge 1111 can be reduced; on the other hand, the assembly of the rotating shaft 11 and the driving hole 123 can be facilitated, thereby improving the assembly efficiency. If the radius of the matching arc surface 12311 is less than 3 mm, when the rotating shaft 11 is inserted into the driving hole 123, the radius of the matching arc surface 12311 is too small, which increases the difficulty of inserting the rotating shaft 11 into the driving hole 123, thereby affecting the assembly efficiency. At the same time, during the process of inserting the rotating shaft 11 into the driving hole 123, the outer wall surface of the rotating shaft 11 is easily rubbed with the matching arc surface 12311, thereby causing damage to the rotating shaft 11 and the matching arc surface 12311. If the radius of the matching arc surface 12311 is greater than 10 mm, the gap between the matching arc surface 12311 and the edge 1111 is large, that is, the gap between the inner wall of the guide hole section 1231 and the outer wall surface of the rotating shaft 11 is large, which leads to a decrease in assembly accuracy, which may affect the overall performance and stability of the whipping assembly 10. Of course, the radius of the matching arc surface 12311 is too large, so that the contact area of the matching arc surface 12311 is reduced, and the contact stress is increased, thereby increasing the friction and wear.

[0044] In other embodiments, in the direction of insertion of the rotating shaft 11, the length of the guide hole section 1231 is greater than or equal to 2 mm and less than or equal to 10 mm; at the same time, the matching arc surface 12311 is a part of a circular arc surface, the radius of the matching arc surface 12311 is greater than or equal to 3 mm and less than or equal to 10 mm, and the effects are the same as above, which will not be repeated here.

[0045] Please continue to refer to Figure 5 In some embodiments, the driving section 111 further comprises an inlet hole section 1232, wherein the inlet hole section 1232 is connected with one end of the guide hole section 1231, and during the process of inserting the rotating shaft 11 into the driving hole 123, the rotating shaft 11 enters the guide hole section 1231 through the inlet hole section 1232; wherein the inner diameter of the inlet hole section 1232 is greater than the inner diameter of the guide hole section 1231. It can be understood that since the rotating shaft 11 needs to enter the guide hole section 1231 after passing through the inlet hole section 1232, by setting the inner diameter of the inlet hole section 1232 to be greater than the inner diameter of the guide hole section 1231, on the one hand, it is convenient for the rotating shaft 11 to be inserted into the driving hole 123; on the other hand, it is convenient for the inner wall of the inlet hole section 1232 to be connected with the inner wall of the guide hole section 1231, so as to improve the stability of the connection between the inlet hole section 1232 and one end of the guide hole section 1231.

[0046] Furthermore, based on the direction of the insertion of the rotating shaft 11, the hole diameter of the guide hole section 1231 is reduced in the middle and increased at both ends, so one end of the guide hole section 1231 can be smoothly connected with the inlet hole section 1232 to disperse the stress of the guide hole section 1231.

[0047] Please refer to Figure 1 and Figure 4 In some embodiments, the driving hole 123 further comprises a main hole section 1233 and a limiting hole section 1234.

[0048] Specifically, one end of the main hole section 1233 is connected with one end of the guide hole section 1231 away from the inlet hole section 1232; that is, when the whipping assembly 10 is applied to the food processor 1, the main hole section 1233 is located above the guide hole section 1231, and the inner diameter of the main hole section 1233 is greater than that of the guide hole section 1231, so that the rotating shaft 11 can be inserted into the main hole section 1233 through the inlet hole section 1232 and the guide hole section 1231. The other end of the main hole section 1233 is connected with the limiting hole section 1234; that is, the main hole section 1233 is located between the limiting hole section 1234 and the guide hole section 1231.

[0049] Please refer to Figure 1 and Figure 4 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, and along the direction of the insertion of the rotating shaft 11, 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 is matched with the matching arc surface 12311. In the present embodiment, the limiting section 1113 is tightly matched with the limiting hole section 1234, so that after the rotating shaft 11 is inserted into the driving hole 123, the limiting hole section 1234 is tightly matched with the limiting section 1113, and the matching arc surface 12311 is also matched with the edge 1111, so that the stability of the rotating shaft 11 installed in the driving hole 123 is improved to avoid the whipping assembly 10 from being separated during rotation.

[0050] Furthermore, the front end of the limiting hole section 1234 has a through hole 1235 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 1235 to facilitate the insertion of the rotating shaft 11 into the driving hole 123.

[0051] Please refer to Figure 1 and Figure 3Further, 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 1234. 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 1234 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 as to improve the safety performance of the beating assembly 10. 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 1234, the hole diameter of the limiting hole section 1234 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 1234, thereby making the sealing ring 112 have good wear resistance to prolong the service life of the sealing ring 112.

[0053] It should be noted that the material of the sealing ring 112 is not specifically limited in the present application, and the material of the sealing ring 112 can be silicone, rubber or TPE (Thermoplastic Elastomer) for example, so that the sealing ring 112 has stable performance, is easy to manufacture and has low cost.

[0054] Please refer to Figure 1 In some embodiments, along the length direction of the driving hole 123, the length dimension of the main hole section 1233 is greater than the length dimension of the guide hole section 1231; in this way, when the rotating shaft 11 is inserted into the driving hole 123, the rotating shaft 11 enters the main hole section 1233 after passing through the guide hole section 1231, and the length dimension of the main hole section 1233 is greater than the length dimension of the guide hole section 1231, so that the main hole section 1233 can accommodate the increased size of the rotating shaft 11; during the working process of the beating assembly 10, the stability of the driving hole 123 and the rotation of the rotating shaft 11 can be maintained.

[0055] Please continue to refer to Figure 1In some embodiments, the angle by which the front end of the edge 1111 along the length direction of the driving hole 123 is deflected relative to the end of the edge 1111 along the length direction of the driving hole 123 is greater than or equal to 8 degrees and less than or equal to 22 degrees; that is, the angle by which the front end of the edge 1111 along the length direction of the driving hole 123 is deflected relative to the end of the edge 1111 along the length direction of the driving hole 123 can be 8 degrees, 15 degrees, 19 degrees, 22 degrees, etc., so that the edge 1111 and the cooperating arc surface 12311 can be better limited and matched. If the angle by which the front end of the edge 1111 along the length direction of the driving hole 123 is deflected relative to the end of the edge 1111 along the length direction of the driving hole 123 is less than 8 degrees, the gap between the edge 1111 and the cooperating arc surface 12311 is small, which increases the difficulty of assembly. If the angle by which the front end of the edge 1111 along the length direction of the driving hole 123 is deflected relative to the end of the edge 1111 along the length direction of the driving hole 123 is greater than 22 degrees, the deflection angle is large, which easily causes the shaft 11 to be unbalanced during rotation, thereby causing vibration and noise; at the same time, the friction between the edge 1111 and the cooperating arc surface 12311 is increased, which reduces the transmission efficiency of the shaft 11.

Furthermore, the driving hole 123 penetrates the end surface of the second part 1212 and extends into the first part 1211, so that when the shaft 11 is inserted into the driving hole 123, part of the shaft 11 can extend into the first part 1211 through the end surface of the second part 1212, and the other part of the shaft 11 extending out of the end surface of the second part 1212, so that the other part of the shaft 11 and the motor shaft 41 can be transmissionally connected.

[0058] 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 greater 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, which can be fixed to the stepped structure 1213 by riveting when the blade is assembled with the frame 121, 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 greater than the diameter of the second part 1212, the stepped structure 1213 includes a first face perpendicular to the axis of the driving hole 123 and a second face parallel to the axis of the driving hole 123, wherein the first face is formed by a part of the end face of the first part 1211, and the second face is an outer wall face 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 face of the first part 1211, and at the same time, the blade also abuts against the outer wall face of the second part 1212, so that the stability of the installation between the beating part 122 and the frame 121 is improved.

[0059] Please continue to refer to Figure 4 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 the first part 1211 has a change trend of being reduced in the middle and increased at both ends in the direction in which the rotating shaft 11 is inserted, so that on the one hand, the end face of the first part 1211 close to the second part 1212 forms the stepped structure 1213 with the second part 1212, thereby facilitating 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 12 and the rotating shaft 11, the middle part of the first part 1211 is reduced relative to the two ends of the first part 1211, so as to facilitate the user to hold.
