Description

Technical Field

[0001] This utility model relates to the field of stirrer technology, specifically to a quick-change structure for a stirring head. Background Technology

[0002] Electric stirrers are suitable for experiments in biology, physicochemistry, cosmetics, health products, food, and reagents. They are experimental devices for mixing and stirring liquids. With a novel design concept and advanced manufacturing process, they offer high torque output at low speeds and excellent continuous operation performance, making them ideal equipment for scientific research, product development, quality control, and production processes in factories, research institutions, universities, and medical units.

[0003] Utility model patent CN220110816U discloses a retractable electric mixer. This utility model includes a housing and an extension rod. The extension rod is slidably connected to the left side of the inner wall of the housing. A mounting plate is fixedly connected to the right side of the inner wall of the housing. A motor is fixedly connected to the left side wall of the mounting plate. A rotating shaft is fixedly connected to the end of the motor's power output shaft, and a locking block is fixedly connected to the end of the rotating shaft. A locking bolt is screwed onto the upper side of the outer wall of the housing. A battery is fixedly connected to the right side wall of the inner cavity of the housing. The battery is electrically connected to the motor via wires. The extension rod has slots at the top and bottom of its inner cavity, and a connecting slot at its left end. This retractable electric mixer has a reasonable structural design, allowing the entire electric mixer to be stored, reducing storage space, and enabling convenient and quick replacement of the mixing head.

[0004] While the aforementioned utility model allows for the replacement of the stirring head, the process requires pushing both push rods to the right with both hands to disengage the locking rod from the pin head. Then, the two pin heads at both ends must be pulled outwards to disengage the rod from the slot, allowing the connecting rod to leave the connecting groove and thus enabling the stirring head to be replaced. This method is cumbersome and inconvenient. Therefore, we propose a quick-change structure for the stirring head. Utility Model Content

[0005] This invention provides a quick-change structure for the stirring head to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-change mixing head structure includes an electric mixer body, a mixing head connected to the left end of the electric mixer body, and an auxiliary mechanism installed on the left end of the outer surface of the electric mixer body.

[0008] The auxiliary mechanism includes an auxiliary sleeve, an auxiliary ring welded to the left end of the auxiliary sleeve, and a limiting frame welded to the right side surface of the auxiliary ring. The limiting frame has a limiting block inside, a limiting groove is formed on the surface of the auxiliary ring at the installation position of the limiting frame, and an auxiliary groove is formed in the middle of the inner surface of the auxiliary ring.

[0009] This feature allows for quick control of the two limiting mechanisms located on both sides of the stirring rod via an auxiliary mechanism, enabling workers to easily replace the stirring head.

[0010] As a preferred technical solution, the limiting block is welded to the left end of the outer surface of the electric mixer body, and the overall shape of the limiting groove is L-shaped.

[0011] As a preferred technical solution, the internal dimensions of the limiting frame are equal to the dimensions of the limiting block, and the limiting block can move in both the vertical and horizontal directions within the L-shaped limiting groove.

[0012] These two features ensure that the auxiliary mechanism can be fixed on the outside of the limit block under the action of the limit frame, while the L-shaped limit groove restricts the horizontal movement of the limit block when it moves into the vertical area of ​​the L-shaped limit groove.

[0013] As a preferred technical solution, the electric mixer body is provided with a stirring rod inside, and the front and rear sides of the left end of the outer surface of the stirring rod are equipped with limit mechanisms, and a locking mechanism is installed on one side of each limit mechanism.

[0014] This feature ensures that the limiting mechanism is fixed in place by the locking mechanism, preventing the mixing head from falling off if the limiting mechanism accidentally disengages.

[0015] As a preferred technical solution, the locking mechanism includes a limiting shell, a sliding rod welded to the upper end of the inside of the limiting shell, and a fixed shaft welded to the lower end of the right side surface inside the limiting shell. The left end of the fixed shaft is slidably connected to a limiting insert rod. A spring is welded to the right side surface of the limiting insert rod. A sliding connecting block is slidably connected to the sliding rod. The lower end of the sliding connecting block is welded to the limiting insert rod.

[0016] This design allows the movement of the limiting mechanism to be unlocked simply by pushing the sliding connecting block to move on the sliding rod, thus disengaging the limiting rod from the limiting hole inside the limiting mechanism.

[0017] As a preferred technical solution, the width of the auxiliary groove is greater than the thickness of the sliding connecting block, the sliding connecting block is located inside the auxiliary groove, and the sliding connecting block does not contact the auxiliary groove.

[0018] This feature ensures that the auxiliary mechanism will not come into contact with the stirring rod or the locking mechanism when the stirring rod is rotating, thus not affecting the rotation of the stirring rod.

[0019] As a preferred technical solution, the inner diameter of the auxiliary sleeve is equal to the outer diameter of the left end of the electric mixer body, and the horizontal length of the limiting groove is equal to the maximum stroke of the sliding connecting block.

[0020] This design allows the auxiliary ring to pull the sliding limit block along the sliding rod when the auxiliary sleeve is pushed to the right. When the auxiliary sleeve reaches its maximum distance, the limit block contacts the bottom of the limit groove and cannot move further. At this point, the sliding connecting block, driven by the auxiliary sleeve, pulls the limit rod away from the limit mechanism, thus unlocking the limit mechanism and allowing it to move.

[0021] As a preferred technical solution, a connecting rod is provided at the right end of the stirring head, and a slot for inserting the connecting rod is provided on the left side surface of the stirring rod.

[0022] With this feature, the connecting rod inserted into the slot is fixed in the slot by the limiting mechanism, so that the connecting rod can be limited by the fixing mechanism. When it is necessary to replace the stirring head, the limiting mechanism needs to be pulled open first.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. When it is necessary to replace the stirring head, push the auxiliary sleeve to the right, so that the auxiliary ring drives the sliding connecting block to the right, so that the limit rod can leave the limit mechanism. Then, the position of the auxiliary sleeve is fixed by the limit groove and the limit block, and the position of the sliding connecting block is fixed. Then, the limit mechanism can be easily operated to replace the stirring head.

[0025] 2. Through the auxiliary mechanism, the auxiliary groove on the inner side of the auxiliary ring simultaneously locks the sliding connecting blocks on both sides. When the auxiliary sleeve is pushed, the sliding connecting blocks on both sides can be moved synchronously, so that the user can easily control the locking mechanism on both sides at the same time. The locking mechanism on both sides can be unlocked synchronously by pushing with one hand through the auxiliary mechanism, without the need for separate operation, reducing steps and enabling faster replacement of the stirring head.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-4 This embodiment provides a technical solution:

[0034] A quick-change mixing head structure includes an electric mixer body 100, a mixing head 200 connected to the left end of the electric mixer body 100, and an auxiliary mechanism 300 installed on the left end of the outer surface of the electric mixer body 100.

[0035] The auxiliary mechanism 300 includes an auxiliary sleeve 301, an auxiliary ring 302 welded to the left end of the auxiliary sleeve 301, and a limiting frame 305 welded to the right surface of the auxiliary ring 302. The limiting frame 305 has a limiting block 306 inside. A limiting groove 304 is opened on the surface of the auxiliary ring 302 at the installation position of the limiting frame 305. An auxiliary groove 303 is opened in the middle of the inner surface of the auxiliary ring 302. Through the above mechanism, the locking mechanisms 103 on both sides can be moved conveniently at the same time through the auxiliary mechanism 300. The locking mechanism 103 can also be fixed by fixing the auxiliary mechanism 300, which is convenient for the user to operate the limiting mechanism 102 and for the user to replace the stirring head.

[0036] Furthermore, such as Figure 4As shown, the limiting block 306 is welded to the left end of the outer surface of the electric mixer body 100. The limiting groove 304 has an overall L-shaped structure. The internal dimensions of the limiting frame 305 are equal to the dimensions of the limiting block 306. The limiting block 306 can move in both the vertical and horizontal directions within the L-shaped limiting groove 304. When the limiting block 306 moves to the vertical area of ​​the limiting groove 304, the auxiliary sleeve 301 is restricted from moving in the horizontal direction by the limiting block 306.

[0037] In this embodiment, as Figure 2 As shown, the electric mixer body 100 is equipped with a stirring rod 101 inside. Limiting mechanisms 102 are installed on both the front and rear sides of the left end of the outer surface of the stirring rod 101. Each limiting mechanism 102 is equipped with a locking mechanism 103 on one side. The locking mechanism 103 prevents the limiting mechanism 102 from moving due to centrifugal force during the start-up process of the electric mixer body 100.

[0038] In this embodiment, as Figure 3 As shown, the locking mechanism 103 includes a limiting shell 1031, a sliding rod 1032 welded to the upper end of the inside of the limiting shell 1031, and a fixed shaft 1033 welded to the lower end of the right side surface inside the limiting shell 1031. The left end of the fixed shaft 1033 is slidably connected to a limiting rod 1035. A spring 1034 is welded to the right side surface of the limiting rod 1035. A sliding connecting block 1036 is slidably connected to the sliding rod 1032. The lower end of the sliding connecting block 1036 is welded to the limiting rod 1035. The movement of the limiting rod 1035 can be controlled by the movement of the sliding connecting block 1036.

[0039] In this embodiment, as Figure 4 As shown, the width of the auxiliary groove 303 is greater than the thickness of the sliding connecting block 1036. The sliding connecting block 1036 is located inside the auxiliary groove 303 and does not contact the auxiliary groove 303. When the sliding connecting block 1036 rotates with the rotation of the stirring rod 101, the auxiliary groove 303 will not affect its rotation.

[0040] In this embodiment, as Figure 1 As shown, the inner diameter of the auxiliary sleeve 301 is equal to the outer diameter of the left end of the electric mixer body 100, and the horizontal length of the limiting groove 304 is equal to the maximum stroke of the sliding connecting block 1036, ensuring that when the auxiliary sleeve 301 moves to the rightmost end, the limiting rod 1035 can disengage from the limiting mechanism 102.

[0041] In this embodiment, as Figure 2As shown, a connecting rod 201 is provided at the right end of the stirring head 200. A slot for inserting the connecting rod 201 is provided on the left side surface of the stirring rod 101. A limiting mechanism 102 is provided in the slot area to restrict the connecting rod 201 in the slot. To remove the connecting rod 201, the limiting mechanism 102 must first be pulled out. The presence of the limiting mechanism 102 can restrict and fix the connecting rod 201.

[0042] It is worth noting that the structure and working principle of the electric mixer body 100, the limiting mechanism 102, the locking mechanism 103, and the mixing head 200 involved in this embodiment are all technologies that have been disclosed in the prior art, and will not be described in detail here.

[0043] In the specific use of the quick-change structure for the stirring head in this embodiment, when it is necessary to replace the stirring head 200, first hold the auxiliary sleeve 301 and push the auxiliary sleeve 301 to the right until the limiting block 306 contacts the left side surface of the limiting groove 304. Then, control the auxiliary sleeve 301 to rotate, so that the limiting block 306 enters the vertical area of ​​the limiting groove 304, so that the auxiliary sleeve 301 cannot move horizontally. During the process of the auxiliary sleeve 301 moving to the right, the auxiliary ring 302 drives the sliding connecting block 1036 to move to the right along the sliding rod 1032 through the auxiliary sleeve 301. When the auxiliary sleeve 301 moves to the rightmost end, the limiting rod 1035 can disengage from the limiting mechanism 102. Then, the user pulls the limiting mechanisms 102 on both sides with both hands to move outward. The stirring head 200 will move downward under the action of gravity, so that the connecting rod 201 disengages from the stirring rod 101. Then the user can replace the stirring head 200.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
