Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer. Background Art

[0002] A mixer, also known as a mixing instrument or an oscillating mixer, is a commonly used device in laboratories and is widely used in research fields such as medicine, biochemistry, genetic engineering, and pharmaceuticals. It is mainly used for effectively oscillating and mixing various liquids, liquid-solid mixtures, solid-solid (powders), etc. in the laboratory.

[0003] For example, a rotary mixer with the patent publication number CN220696522U includes a frame, a rotary frame, a mounting frame, and a test tube rack; the left and right sides of the rotary frame are respectively provided with a first rotating shaft and a second rotating shaft, the first rotating shaft is a hollow rotating shaft, a fixed shaft is provided on the frame, the first rotating shaft rotates and slidably sleeved on the fixed shaft, the second rotating shaft is rotatably arranged on the frame and connected to the motor on the frame, a second spring is also sleeved on the fixed shaft, and a supporting edge for blocking the second spring is provided on the outer side wall of the first rotating shaft; a convex ball is also provided on the side wall of the rotary frame where the second rotating shaft is located, and a plurality of top blocks are provided on the frame corresponding to the convex ball; the mounting frame is detachably mounted on the rotary frame, a fixing member for fixing the mounting frame is provided on the rotary frame, a mounting hole for mounting the test tube rack is provided on the mounting frame, and the test tube rack is detachably arranged in the mounting hole.

[0004] Although this rotary mixer enables the test tubes to have more than one single motion mode, improves the mixing effect, and is convenient for replacing the test tube fixture with good applicability, the above-mentioned rotary mixer also has certain limitations in actual operation. Specifically, when using this mixer to process multiple reagents, all test tubes will rotate at the same speed during the mixing process, while different reagents may require different mixing speeds to achieve the best effect. This requires the operator to wait until a batch of reagents with the same mixing speed requirement is processed before changing to another batch of reagents that require different mixing speeds, which will increase the overall mixing time of the reagents and reduce the work efficiency.

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will provide a detailed description of the specific embodiments of the present utility model in conjunction with the drawings in the specification.

[0027] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0029] Example 1

[0030] Reference Figures 1 to 6 , which is the first embodiment of the present utility model. This embodiment provides a mixer.

[0031] Specifically, it includes a support assembly 100, which includes a support base 101, a support rod 102 connected to the top of the support base 101, a fixed block 103 arranged on the top of the support base 101, and a slideway 104 arranged on the top of the fixed block 103. Among them, the support rod 102 can be replaced with other components according to requirements, such as being replaced with a bearing seat of corresponding size;

[0032] Similarly, other components can be added to the slideway 104 as needed to improve accuracy, such as a threaded rod. However, it should be noted that the components connected to the fixed block 103 also need to be replaced accordingly.

[0033] In summary, in order to reduce wear, the support rod 102 can be replaced with a bearing seat, and at the same time, a threaded rod can be added to the slideway 104 to improve accuracy.

[0034] Example 2

[0035] Reference Figures 1 to 6 , which is the second embodiment of the present utility model. Based on the previous embodiment, the difference is that this embodiment can make different test tubes rotate at different speeds.

[0036] Specifically, a power assembly 200 is arranged on the support rod 102, which includes a rotating member 201, a linkage member 202 connected to the top of the rotating member 201, a moving frame 203 connected to the linkage member 202, a moving block 204 connected to the bottom of the moving frame 203, and a threaded rod 205 connected to the inner wall of the moving block 204. Among them, when the rotating member 201 rotates, it will drive one end of the linkage member 202 to move, so that the other side of the linkage member 202 will move.

[0037] The rotating member 201 includes an eccentric wheel 201a, a limit ring 201b connected to one side of the eccentric wheel 201a, and a rotating shaft 201c connected to one side of the eccentric wheel 201a. Among them, when the rotating shaft 201c rotates, it will drive the eccentric wheel 201a and the limit ring 201b to rotate eccentrically.

[0038] The linkage member 202 includes a rotating rod 202a, a fixed shaft 202b connected to one side of the rotating rod 202a, a rotating wheel 202c rotatably connected to the outer wall of the fixed shaft 202b, a connecting shaft 202d connected to the other side of the rotating rod 202a, and a chute 202e opened on the outer wall of the rotating rod 202a. Among them, there are two fixed shafts 202b, and rotating wheels 202c are arranged on both fixed shafts 202b.

[0039] The outer wall of the rotating shaft 201c is rotatably connected to the inner wall of the support rod 102. A pulley 201d is connected to one side of the rotating shaft 201c. Among them, the pulley 201d is used to connect to the motor. When the motor drives the pulley 201d to rotate, it will drive the rotating shaft 201c and the eccentric wheel 201a to rotate.

[0040] The outer wall of the rotating wheel 202c is in contact with the outer wall of the eccentric wheel 201a, and the outer wall of the other side of the rotating wheel 202c is in contact with the outer wall of the limiting ring 201b. Among them, the rotating wheel 202c is located between the eccentric wheel 201a and the limiting ring 201b. When the eccentric wheel 201a rotates, it will push the rotating wheel 202c to move, and the limiting ring 201b is used to limit the moving direction of the rotating wheel 202c, so that the rotating wheel 202c moves in a specified direction.

[0041] The inner wall of the chute 202e is slidably connected to the top of the moving frame 203, the outer wall of the moving block 204 is slidably connected to the outer wall of the slideway 104, and the outer wall of the threaded rod 205 is slidably connected to the inner wall of the fixed block 103. Among them, when the moving frame 203 can slide in the chute 202e, thereby changing the fulcrum of the rotating rod 202a, so that the movement amplitude of the rotating rod 202a during swinging.

[0042] In summary, when it is necessary to change the swinging amplitude of the side of the rotating rod 202a where the connecting shaft 202d is installed, move the moving block 204 in the direction away from the eccentric wheel 201a, thereby changing the fulcrum of the rotating rod 202a. At this time, the moving distance of the side of the rotating rod 202a where the connecting shaft 202d is installed will become shorter. When the eccentric wheel 201a rotates, the swinging amplitude of the side of the rotating rod 202a where the connecting shaft 202d is installed will decrease.

[0043] Embodiment 3

[0044] Refer to Figures 1 to 6 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that different clamps can be installed in the opening 304 to clamp test tubes with different diameters.

[0045] Specifically, a triangular frame 105 is installed on the top of the support seat 101, and a limiting rod 106 is installed on the top of the triangular frame 105. Among them, the triangular frame 105 that supports and limits the rod 106 can be replaced according to needs, and other multifunctional brackets that can be rotated and height-adjusted can be replaced.

[0046] A placing assembly 300 is connected to the inner wall of the limiting rod 106. The placing assembly 300 includes a swinging rod 301, a fixing rod 302 rotatably connected to the top of the swinging rod 301, a fixing plate 303 connected to the top of the fixing rod 302, and an opening 304 formed in the outer wall of the fixing plate 303. The outer wall of the fixing rod 302 is slidably connected to one side of the limiting rod 106. The bottom of the swinging rod 301 is rotatably connected to the outer wall of the rotating shaft 201c. Among them, there are two placing assemblies 300, and the swinging rods 301 in the two placing assemblies 300 are respectively rotatably connected to the rotating shaft 201c and the connecting shaft 202d. Therefore, when the rotating shaft 201c and the connecting shaft 202d move, they will also drive the swinging rod 301 to move, thereby driving the fixing rod 302 to move up and down, and then driving the fixing plate 303 to move up and down. In this way, the test tubes in the opening 304 can perform the mixing work.

[0047] In summary, when the eccentric wheel 201a rotates, it will push the rotating wheel 202c to move, so that both sides of the rotating rod 202a move. At this time, the swinging rods 301 connected to the rotating shaft 201c and the connecting shaft 202d move at the same frequency. When the moving block 204 is pushed to move in the direction away from the eccentric wheel 201a, the fulcrum of the rotating rod 202a will be changed, thereby slowing down the movement frequency of the swinging rod 301 connected to the connecting shaft 202d, and then reducing the movement frequency of the corresponding fixing plate 303. At this time, two reagents that need to be mixed at different speeds can be placed on the two fixing plates 303 to perform the mixing work simultaneously. In this way, there is no need to queue up, improving the applicability and working efficiency of the mixer.
