Abstract
Description
Technical Field
[0001] This utility model relates to the field of agitator technology, and more specifically, to a quick-release electric agitator structure. Background Technology
[0002] Electric mixers, as common devices for mixing and stirring materials, are widely used in many fields such as chemical, food, pharmaceutical, and laboratory industries. In these applications, the ease of assembly and disassembly of the mixing head is particularly important to meet different mixing needs and facilitate cleaning and maintenance. In traditional electric mixers, to improve the efficiency of assembly and disassembly, a threaded connection is typically used between the mixing head and the output end of the mixer body. Specifically, a stud is fixed to the end of the mixing head, while a threaded hole that matches the stud is provided at the output end of the mixer body. The connection between the mixing head and the mixer body is achieved through the fit between the stud and the threaded hole.
[0003] However, this threaded connection method has obvious drawbacks. After repeated disassembly and use, the threads on the stud surface are prone to wear. Once the threads are worn, it will seriously affect the stability and reliability of the connection between the mixing head and the mixer output end, which may lead to loosening or shaking during the mixing process. This will not only affect the mixing effect, but may also pose a safety hazard. Therefore, it is necessary to replace the connecting parts to restore normal use.
[0004] In conventional structures, the stud and the mixing head are fixedly connected. When the threads of the stud wear down to a certain extent and can no longer guarantee a normal connection, the stud and the mixing head need to be replaced manually. This will undoubtedly cause a lot of material waste, because many times the mixing head itself is not damaged, only the stud part has a problem, but it has to be discarded together, which increases the cost of use and does not conform to the concept of energy conservation and environmental protection. Utility Model Content
[0005] This utility model provides a quick-release electric mixer head structure, which solves the technical problems existing in the prior art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A quick-release electric mixer structure includes a mixer body and a mixing head detachably mounted on the output end of the mixer body. A mounting stud is provided between the mixing head and the mixer body. The output end of the mixing head has a threaded slot that mates with the mounting stud. There are two sets of mounting studs, symmetrically distributed vertically, with a flip-and-replacement part between them. A U-shaped mounting base is fixed to the top of the mixing head. The flip-and-replacement part is located inside the mounting base. C-shaped grooves are provided through the two side walls of the mounting base. Through holes communicating with the C-shaped grooves are provided through the top of both sides of the mounting base. A limiting part is provided within the through holes to ensure the stability of the flip-and-replacement part during rotation. Furthermore, the flipping replacement part includes a connecting column that is vertically fixed between the two sets of mounting studs, and C-shaped grooves are provided through both sides of the mounting base. A support column that is perpendicularly fixed to the connecting column rod is provided deep inside the C-shaped groove. Furthermore, the limiting part includes a limiting rod that slides within the insertion hole, the bottom end of the limiting rod passing through the C-groove and abutting against the body of the support column. Furthermore, the inner wall of the support column is provided with a vertical through hole, and the top of the mounting base is also provided with a vertical groove corresponding to and communicating with the through hole. The vertical groove is provided with a mating part to ensure the firmness of the connecting column after it is flipped. Furthermore, the docking part includes a vertically sliding rod that slides in the vertical groove. The top end of the rod passes through the mounting base and is fixed with a sliding piece. The sliding piece is slidably sleeved on the body of the limiting rod, and both ends of the sliding piece are fixedly connected to the mounting base with spring telescopic rods. Furthermore, a clamping block that abuts against the sliding plate is fixed at the top of the limiting rod, a screw head is fixed at the bottom of the limiting rod, and a threaded locking hole corresponding to the screw head is opened on the inner wall of the bottom of the C-shaped groove. Compared with existing technologies, the advantages of this invention are as follows: By using a flip-over replacement part and two sets of mounting studs, a dual-stud alternating usage mode is constructed. This differs from the drawback of traditional mixers where the mixing head end has only a single mounting stud, leading to complete failure upon wear. When one set of mounting studs in this structure experiences thread wear due to repeated disassembly and assembly, affecting the connection stability with the mixer body's output end, the flip-over replacement part allows for quick switching to another set of spare mounting studs, maintaining an effective connection between the mixing head and the mixer body. Thus, when mounting studs wear out, there is no need to discard the studs along with the mixing head; only the worn studs need to be replaced, significantly reducing material waste and lowering operating costs.

[0010] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0011] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0012] Please see Figure 1-5A quick-release electric mixer structure includes a mixer body 1 and a mixer head 2 detachably mounted on the output end of the mixer body 1. A mounting stud 3 is provided between the mixer head 2 and the mixer body 1. The output end of the mixer head 2 has a threaded slot that mates with the mounting stud 3. By screwing the mounting stud 3 into or out of the threaded slot, the mixer head 2 and the mixer body 1 can be connected by threads. The threaded fit allows for quick connection between the two.
[0013] For further details, please refer to Figure 2 The system comprises two sets of mounting studs 3, symmetrically distributed vertically, with a flip-and-replace section between them. A U-shaped mounting base 4 is fixed to the top of the stirring head 2, with the flip-and-replace section located inside the mounting base 4. This design, along with the flip-and-replace section and the two sets of mounting studs 3, creates a dual-stud-3 alternating usage mode. This differs from traditional mixers where the stirring head 2 has only a single mounting stud 3, leading to complete failure upon wear. In this system, when one set of mounting studs 3 experiences thread wear due to repeated disassembly and assembly, affecting the connection stability with the output end of the mixer body 1, the flip-and-replace section allows for quick switching to the other set of spare mounting studs 3, maintaining effective connection between the stirring head 2 and the mixer body 1. Thus, when a mounting stud 3 wears, it is not necessary to discard the entire set along with the stirring head 2; only the worn stud 3 needs to be replaced, significantly reducing material waste and lowering operating costs.
[0014] For further details, please refer to Figure 3-5 The flipping and replacement unit includes a connecting column 5 vertically fixed between two sets of mounting studs 3. C-shaped grooves are formed through both sides of the mounting base 4. A support column 6, perpendicular to the shaft of the connecting column 5, is located deep within the C-shaped groove. Through the connection column 5 and the support column 6, the connecting column 5 serves as the intermediate support and core carrier for the flipping of the two sets of mounting studs 3, providing stable vertical support for the symmetrical layout of the two mounting studs 3. The support column 6 fits into the C-shaped groove. When it is necessary to flip and replace the mounting studs 3, the C-shaped groove provides a flipping guide space for the support column 6. The operator can easily flip the worn upper mounting stud 3 to a non-working position by moving the connecting column 5, causing the upper and lower sets of mounting studs 3 to rotate, and switch the lower spare mounting stud 3 to the connection position that matches the output end of the mixer body 1.
[0015] For further details, please refer to Figure 3 and Figure 4 The top of both sides of the mounting base 4 is provided with through holes that communicate with the C-shaped groove. The through holes are provided with limiting parts to ensure the stability of the flip-up replacement part when it rotates. By setting the limiting parts, the rotation of the support column 6 in the C-shaped groove can be effectively restricted to prevent it from shifting due to rotation, thereby improving the stability of the connecting column 5 when it flips.
[0016] For further details, please refer to Figure 3 and Figure 4 The limiting part includes a limiting rod 11 that slides in the through hole. The bottom end of the limiting rod 11 passes into the C-shaped groove and abuts against the column body of the support column 6. With the setting of the limiting part, when the connecting column 5 drives the support column 6 to rotate, the limiting rod 11 is located in the C-shaped groove and contacts the support column 6, which can effectively limit the support column 6 to the inner depth of the C-shaped groove, prevent it from shaking or shifting randomly in the C-shaped groove, and ensure that the flipping trajectory of the connecting column 5 and the upper and lower sets of mounting studs 3 is stable and controllable, so that the stud switching action is precise and smooth. Furthermore, when both sets of mounting studs 3 show wear after sufficient use, simply pulling up the limiting rod 11 retracts it into the insertion hole, releasing the constraint on the support column 6. At this point, simply pulling the connecting column 5 allows the support column 6 to be easily removed from the C-groove, separating the replacement unit from the mounting base 4. This design allows the worn mounting studs 3 and the replacement unit to be quickly and completely disassembled, facilitating individual replacement without requiring modification or disposal of the stirring head 2 body. Compared to the traditional structure where the stirring head and mounting studs 3 are fixedly connected and must be replaced as a whole after wear, this design further simplifies the maintenance process and reduces replacement difficulty and material costs.
[0017] For further details, please refer to Figure 3 and Figure 4 The inner wall of the support column 6 has a vertical through hole 9, and the top of the mounting base 4 also has a vertical groove corresponding to and connected to the through hole 9. The vertical groove has a mating part to ensure the firmness of the connecting column 5 after it is flipped. The docking part includes a vertically sliding rod 8 in the vertical groove. The top end of the rod 8 passes through the mounting base 4 and is fixed with a sliding piece 7. The sliding piece 7 is slidably sleeved on the body of the limiting rod 11, and both ends of the sliding piece 7 are fixedly connected to the mounting base 4 with a spring telescopic rod 10. The top of the limiting rod 11 is fixed with a clamping block 12 that abuts against the sliding plate 7, and the bottom of the limiting rod 11 is fixed with a screw head. A threaded locking hole 13 corresponding to the screw head is opened on the inner wall of the bottom of the C-shaped groove. Through the arrangement of the sliding plate 7, the insert rod 8, the insert hole 9, the spring telescopic rod 10, and the screw head, a precise and reliable docking and locking mechanism is constructed. (Refer to the attached instruction manual.) Figure 4As can be seen, under the elastic force of the spring telescopic rod 10, the slider 7 drives the limiting rod 11 to be suspended on one side of the support column 6. Thus, when the connecting column 5 needs to be rotated, the limiting rod 11 can effectively limit the support column 6. After the rotation is completed, the insertion hole 9 on the connecting column 5 will be precisely aligned with the insertion rod 8. At this time, the slider 7 or the clamping block 12 is pressed down to push the insertion rod 8 to be precisely inserted into the insertion hole 9. By using the insertion and cooperation of the two, the rotational freedom and vertical displacement of the connecting column 5 in the working state are restricted, ensuring that the installed stud 3 after flipping is stably kept in the connection position that matches the output end of the mixer. At the same time, the limiting rod 11 will move synchronously with the downward movement of the slider 7, so that the screw head at the bottom of the limiting rod 11 is precisely aligned with the threaded locking hole 13 on the inner wall of the C-shaped groove. Then, the clamping block 12 is turned to screw the screw head into the threaded locking hole 13, which can counteract the elastic force of the spring telescopic rod 10 on the slider 7, so that the insertion rod 8 is stably kept in the insertion hole 9, forming a double locking of "insertion + thread".
[0018] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
