[0037] Machines such as kitchen mixers can conveniently and quickly process the food mixing and processing needs through accessories and are very popular in the market. However, as the amount of food to be mixed increases or the proportion of different food formulas changes, the required mixing force increases, so the connection and cooperation between the machine and the accessories wear more, and the accessories are worn and squeezed and deformed, thus affecting the installation and removal of the accessories, which will greatly affect the user experience when customers use the product.

[0038] To solve the above problems, the present utility model proposes an anti-jamming structure and a kitchen mixer, aiming to provide an anti-jamming structure and a kitchen mixer that can avoid the accessories from being jammed and affecting the taking and placing. Figures 1 to 6 It is a schematic structural diagram of an embodiment provided by the anti-jamming structure of the present utility model.

[0039] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the anti-jamming structure 100 includes an output shaft 1, a mixing member 2, and an anti-jamming portion 3; the output shaft 1 is arranged in a long shape, provided with a driving end and a free end, and the kitchen mixer 200 is drivingly connected to the driving end; the mixing member 2 is convexly provided with a mounting block 21, and the mounting block 21 is concavely provided with an assembly groove 211, and the free end of the output shaft 1 is accommodated in the assembly groove 211 to drivingly connect the mixing member 2; the anti-jamming portion 3 is arranged in the assembly groove 211 to prevent the output shaft 1 from being jammed in the assembly groove 211 when driving the mixing member 2.

[0040] According to the technical solution of the present utility model, the mixer is drivingly connected to the output shaft 1, and then drives the mixing member 2 to rotate to mix food. At the same time, by arranging the anti-jamming portion 3 in the assembly groove 211, that is, at the position where the output shaft 1 is drivingly connected to the mixing member 2, the phenomenon that the mixing member 2 is stuck with the output shaft 1 and is difficult to take is avoided.

[0041] It can be understood that the mounting block 21 can also be protruded from the output shaft 1. Further, an assembly groove 211 is recessed in the mounting block 21, and the driving end of the stirring member 2 is received in the assembly groove 211. Thus, the output shaft 1 can still drive the stirring member 2 to stir, and the anti-jamming portion 3 is disposed in the assembly groove 211 to prevent the output shaft 1 from jamming in the assembly groove 211 when driving the stirring member 2.

[0042] Further, please refer to Figure 1 and Figure 2 , a convex block 11 is protruded horizontally from the free end of the output shaft 1, and the anti-jamming portion 3 includes the convex block 11; the assembly groove 211 includes a first groove 2111 and a second groove 2112. The first groove 2111 is used to receive the free end of the output shaft 1, and the second groove 2112 receives the convex block 11; wherein, an avoidance groove 2113 is recessed in the side wall of the first groove 2111 relative to the contact portion between the convex block 11 and the second groove 2112. It can be understood that in order to avoid the stirring member 2 being stuck with the output shaft 1, and thus it is difficult to take it. Specifically, a convex block 11 is protruded horizontally from the free end of the output shaft 1, and the anti-jamming portion 3 includes the convex block 11; the assembly groove 211 includes the first groove 2111 and the second groove 2112. The first groove 2111 is used to receive the free end of the output shaft 1, and the second groove 2112 receives the convex block 11; wherein, an avoidance groove 2113 is recessed in the side wall of the first groove 2111 relative to the contact portion between the convex block 11 and the second groove 2112. Thus, through the arrangement of the first groove 2111 and the second groove 2112, the driving connection between the output shaft 1 and the mounting block 21 is realized. That is, during the rotation of the output shaft 1, the stirring member 2 rotates through the cooperation between the convex block 11 and the side wall of the second groove 2112; at the same time, when the resistance of stirring is too large, deformation will occur between the convex block 11 and the side wall of the second groove 2112. This deformation is the main reason for the difficulty in disassembling the stirring member 2 and the output shaft 1 after stirring. Thus, through the avoidance groove 2113 being recessed in the side wall of the first groove 2111 relative to the contact portion between the convex block 11 and the second groove 2112, the deformation amount generated by the convex block 11 is directed to the avoidance groove 2113, thereby alleviating the deformation pressure between the convex block 11 and the output shaft 1. Thus, after stirring, the user can easily disassemble the output shaft 1 and the stirring member 2, which is convenient for taking and replacing accessories.

[0043] It can be understood that the convex block 11 and the output shaft 1 are integrally provided.

[0044] In addition, please refer to Figure 1 and Figure 3 A through hole 12 is horizontally penetrated through the free end of the output shaft 1; the anti-jamming structure 100 further includes a pin shaft 4, one end of which is received in the through hole 12, and the other end protrudes from the through hole 12 to form a convex portion 41; the anti-jamming portion 3 includes the convex portion 41; the assembly groove 211 includes a first groove 2111 and a second groove 2112. The first groove 2111 is used to receive the free end of the output shaft 1, and the second groove 2112 receives the convex portion 41 of the pin shaft 4; wherein, an avoidance groove 2113 is recessed in the side wall of the first groove 2111 relative to the contact portion between the convex portion 41 and the second groove 2112. It can be understood that, in order to prevent the mixing member 2 from being jammed with the output shaft 1, and thus making it difficult to take out, specifically, a through hole 12 is horizontally penetrated through the free end of the output shaft 1; the anti-jamming structure 100 further includes the pin shaft 4, one end of which is received in the through hole 12, and the other end protrudes from the through hole 12 to form the convex portion 41; the anti-jamming portion 3 includes the convex portion 41; the assembly groove 211 includes the first groove 2111 and the second groove 2112. The first groove 2111 is used to receive the free end of the output shaft 1, and the second groove 2112 receives the convex portion 41 of the pin shaft 4; wherein, an avoidance groove 2113 is recessed in the side wall of the first groove 2111 relative to the contact portion between the convex portion 41 and the second groove 2112; thus, through the arrangement of the first groove 2111 and the second groove 2112, the driving connection between the output shaft 1 and the mounting block 21 is realized, that is, during the rotation of the output shaft 1, the mixing member 2 is rotated by the cooperation of the convex portion 41 and the side wall of the second groove 2112; at the same time, when the resistance of stirring is too large, deformation will occur between the convex portion 41 and the side wall of the second groove 2112. This deformation is the main reason for the difficulty in disassembling the mixing member 2 from the output shaft 1 after stirring. Thus, an avoidance groove 2113 is recessed in the side wall of the first groove 2111 relative to the contact portion between the convex portion 41 and the second groove 2112, so as to direct the deformation amount of the convex portion 41 to the avoidance groove 2113, thereby alleviating the deformation pressure between the convex portion 41 and the output shaft 1. Thus, after stirring, the user can easily disassemble the output shaft 1 from the mixing member 2, which is convenient for taking and replacing accessories.

[0045] It can be understood that the bump 11 and the output shaft 1 are integrally provided. On the one hand, it is relatively difficult during the production process. In addition, if the bump 11 is excessively squeezed and deformed, a new output shaft 1 needs to be replaced, and thus the maintenance cost is too high, which is not conducive to the economy of the kitchen mixer 200. On the other hand, since the bump 11 protrudes directly from the free end of the output shaft 1, when the bump 11 is engaged with the second groove 2112, the cross-section where the bump 11 and the output shaft 1 intersect is a dangerous cross-section, and thus it is easy to break here, causing the driving function of the output shaft 1 to fail. Therefore, a through hole 12 is provided through the free end of the output shaft 1, which makes the production process of the output shaft 1 easier. In addition, a detachable installation is achieved between the pin shaft 4 and the output shaft 1, that is, the convex portion 41 of the pin shaft 4 is detachable relative to the output shaft 1. Thus, when the stirring member 2 is stirring and the stirring pressure is too high, resulting in a large deformation amount of the convex portion 41, a new convex portion 41 can be replaced by replacing the new pin shaft 4, thereby reducing the cost. Finally, during the stirring process, the stirring pressure borne by the convex portion 41 is shared by the inner wall of the through hole 12 and the circumferential side of the pin shaft 4, thus avoiding the situation of the convex portion 41 breaking, and thus ensuring the reliability of the output shaft 1 to drive the stirring member 2.

[0046] In addition, please refer to Figure 4 and Figure 5, the assembly groove 211 further includes a third groove 2114 which penetrates through the peripheral side of the mounting block 21 and communicates with the second groove 2112. It can be understood that the output shaft 1 is directly received in the first groove 2111 in the up and down direction. Thus, such a setting lacks the limit of the output shaft 1 in the up and down direction. During the stirring process, due to the change of the stirring material in the height direction, the stirring member 2 is likely to rise and fall accordingly. In a more serious situation, during the high-speed rotation of the output shaft 1, the stirring member 2 rising and falling relative to the output shaft 1 may cause the stirring member 2 to directly come out, which poses a hazard to the user and damages the kitchen mixer 200. Therefore, the assembly groove 211 further includes the third groove 2114 which penetrates through the peripheral side of the mounting block 21 and communicates with the second groove 2112. Thus, when the output shaft 1 is received in the first groove 2111 in the up and down direction, the convex portion 41 is received in the second groove 2112. When the mixer rotates, the convex portion 41 turns from the second groove 2112 to the third groove 2114, and then the upper side wall of the third groove 2114 limits the convex portion 41, thereby preventing the stirring member 2 from coming out of the output shaft 1 during the stirring process, and further ensuring the safe use of the kitchen mixer 200.

[0047] Further, please refer to Figure 4 and Figure 5 , the assembly groove 211 further includes a positioning groove 2115 which penetrates through the peripheral side of the mounting block 21 and is provided on one side of the third groove 2114 in the up and down direction. It can be understood that the output shaft 1 has two modes: driving and stopping driving. When the output shaft 1 is driving, the convex portion 41 turns from the second groove 2112 to the third groove 2114. When the driving stops, due to inertia, the stirring member 2 will still turn a little bit, so that the convex portion 41 turns from the third groove 2114 to the second groove 2112 again, which brings great instability during the use process. Therefore, the assembly groove 211 further includes the positioning groove 2115 which penetrates through the peripheral side of the mounting block 21 and is provided on one side of the third groove 2114 in the up and down direction. It can be understood that when installing the output shaft 1 into the assembly groove 211, the convex portion 41 can be rotated and installed into the positioning groove 2115 manually at one time. Thus, no matter whether the rotating shaft is in the driving mode or the non-driving mode, the convex portion 41 is always in the positioning groove 2115, which not only ensures the reliability of the output of the output shaft 1, but also enables the kitchen mixer 200 to operate stably.

[0048] In addition, please refer to Figure 6 , the anti-jamming structure 100 includes an elastic part 5 disposed on the output shaft 1 for providing elastic support to the stirring member 2. It can be understood that due to the change in the height of the stirred material, the driving end of the output shaft 1 moves up and down relative to the mounting end of the kitchen mixer 200, unable to provide a downward force to push the stirring member 2 against the stirred material, which may lead to insufficient stirring of some parts at the bottom of the stirred material. Therefore, the anti-jamming structure 100 includes the elastic part 5 disposed on the output shaft 1 for providing elastic support to the stirring member 2, thus ensuring that the stirring member 2 can also fully stir the bottom of the stirred material.

[0049] Furthermore, the elastic part 5 includes a spring 51 sleeved on the output shaft 1, with one end abutted against the mounting block 21 and the other end abutted against the output end of the kitchen mixer 200. It can be understood that in order to provide a downward pressure to the stirring member 2 to fully stir the bottom of the stirred material, the elastic part 5 includes the spring 51 sleeved on the output shaft 1, with one end abutted against the mounting block 21 and the other end abutted against the output end of the kitchen mixer 200. Thus, the spring 51 is always in a compressed state and has a tendency to extend, providing a force away from each other for the driving end of the stirring member 2 relative to the output shaft 1. That is, during the actual stirring process, even if the height of the stirred material changes, but since the position of the output shaft 1 is relatively fixed, the stirring member 2 can be pressed against the bottom of the stirred material under the action of the elastic force of the spring 51, and thus can be fully stirred. In addition, the setting of the spring can also play a buffering role. Even in the case of large fluctuations, the upward force on the stirring member 2 will be relieved by the spring 51, so that the driving end of the output shaft 1 can play a buffering role relative to the mixer, avoiding impact damage caused by the reason of height fluctuations.

[0050] In addition, please refer to Figure 1 , the part of the stirring member 2 away from the mounting block 21 is spirally arranged. It can be understood that in some embodiments, when the stirring end face of the stirring member 2 is subject to a large stirring resistance, it is easy to stop rotating and malfunction. Therefore, in another embodiment, the part of the stirring member 2 away from the mounting block 21 is spirally arranged. When the stirring end face of the stirring member 2 is subject to a large stirring resistance, due to the spiral arrangement, the area of the stirring end face receiving the resistance is larger, which can well distribute the resistance. In addition, due to the spiral arrangement, when the stirring member 2 faces the stirred material in the height direction, it cuts in obliquely, and thus is easier to overcome the resistance.

[0051] The present utility model also provides a kitchen blender 200. Please refer to Figure 6 , the kitchen blender 200 includes the anti-jamming structure 100. The specific structure of the anti-jamming structure 100 refers to the above embodiments. Since the kitchen blender 200 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0052] Further, please refer to Figure 6 , a receiving groove 201 is recessed in a part of the kitchen blender 200 relative to the stirring member 2 for receiving a stirring container. It can be understood that in some embodiments, the stirring container is directly placed on a plane. When the stirring member 2 rotates, the stirring member 2 drives the stirring material, and the stirring material then drives the stirring container, causing the stirring container to move on the plane, making it difficult to complete the stirring task. Or the user manually fixes the stirring container, but this also increases the operation burden of the user. Therefore, the receiving groove 201 is recessed in a part of the kitchen blender 200 relative to the stirring member 2 for receiving the stirring container. The stirring container is received and fixed through the receiving groove 201, so that the stirring container is fixed relative to the kitchen blender 200, and then the stirring member 2 can better complete the stirring task, reducing the operation burden for the user and facilitating the operation.

[0053] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
