Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically to a vortex mixer. Background Technology

[0002] Vortex mixers, as a common laboratory device, are widely used in biology, chemistry, and other fields for the rapid mixing of liquid samples in test tubes. Their working principle involves a motor-driven tray generating high-frequency vibration or rotation, causing the sample in the test tube to be uniformly mixed under centrifugal force or eddy current. Traditional vortex mixers typically employ a fixed tray structure, usually consisting of a lower support and an upper auxiliary support. When the mixer's actuating unit moves the bottom support, the upper auxiliary support usually does not move with it. While it assists in securing the test tubes in the bottom support, it affects the continuity of the bottom support's movement, resulting in poor consistency between the lower actuating structure and the upper auxiliary support structure, thus impacting the mixing efficiency of the sample in the test tube. Therefore, we propose a vortex mixer. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a vortex mixer, including a mixer body 1, a tray mechanism 2 mounted on the top of the mixer body 1 for placing test tubes, an action unit mounted inside the mixer body 1, the action unit being connected to the tray mechanism 2 for transmission, the action unit driving the action of the tray mechanism 2 to shake and mix the sample in the test tube, and a control panel fixedly mounted on the front side wall of the mixer body 1, through which the running speed and running time of the action unit inside the mixer body 1 can be set.

[0019] like Figure 1 and Figure 2 As shown, the tray mechanism 2 includes a bottom tray 21, which consists of a base 211 and a snap-fit ​​seat 212. The base 211 is snap-fitted and fixed to the output end of the action unit inside the mixer body 1. The surface of the snap-fit ​​seat 212 is evenly provided with slots 213 for inserting test tubes. Both the base 211 and the snap-fit ​​seat 212 are made of rubber material, which provides a certain buffering effect when the action unit inside the mixer body 1 is driven to perform its action, and can protect the test tubes located in the slots 213.

[0020] The top of the mixer body 1 is fixedly equipped with assembly shafts 22 that are symmetrically distributed on the left and right. Assembly frames 23 are respectively snapped onto the outer side walls of the assembly shafts 22. An auxiliary fixing frame 24 is assembled between the two assembly frames 23. By setting the auxiliary fixing frame 24, the test tube can be fixed in the slot 213, and the stability of the test tube can be enhanced during the mixing process of the mixer body 1.

[0021] like Figure 3 As shown, a fixing bolt 25 is fixedly mounted between the auxiliary fixing frame 24 and the assembly frame 23. A handle ring 26 is fixedly connected to the top of the fixing bolt 25. The fixing bolt 25 enables a detachable fixed connection between the auxiliary fixing frame 24 and the assembly frame 23. The size of the auxiliary fixing frame 24 is adapted to the bottom tray 21. When it is necessary to clamp and fix test tubes of different sizes, the bottom tray 21 and the auxiliary fixing frame 24 of the corresponding size can be replaced. The operation of replacing the auxiliary fixing frame 24 is simple and convenient.

[0022] like Figure 3As shown, the assembly frame 23 includes an assembly frame body 231. A positioning groove 232 is provided on one side wall of the assembly frame body 231, and a positioning screw 233 is screwed onto the other side wall of the assembly frame body 231. A handwheel 234 is fixedly connected to the end of the positioning screw 233. By rotating the handwheel 234, the positioning screw 233 can be fastened to the side wall of the assembly shaft 22, thereby fixing the assembly frame 23 at the connection position of the assembly shaft 22.

[0023] like Figure 1 and Figure 3 As shown, a scale 3 is provided on the outer wall of the assembly shaft 22. The assembly position of the two side assembly frames 23 and the assembly shaft 22 can be leveled by the scale 3. After the positions of the two side assembly frames 23 correspond, the auxiliary fixing frame 24 is assembled and fixed with the assembly frame 23 and kept in a horizontal position.

[0024] like Figure 4 As shown, the auxiliary fixing frame 24 includes an upper frame 241 and a lower frame 242. A connecting component 4 is fixedly assembled between the upper frame 241 and the lower frame 242, connecting the upper frame 241 and the lower frame 242 through the connecting component 4. The upper frame 241 and the lower frame 242 are also made of rubber material, which can play a buffering and protective role in the process of limiting and fixing the test tube. Positioning blocks 243 are fixedly connected to the left and right ends of the upper frame 241, respectively. The positioning blocks 243 are used to cooperate with the positioning grooves 232. By setting the positioning blocks 243 and the positioning grooves 232, it is convenient to position and connect the auxiliary fixing frame 24 and the assembly frame 23, thereby facilitating the assembly and fixing of the fixing bolts 25, so that the auxiliary fixing frame 24 and the assembly frame 23 can be better fixed. The bottom of the lower frame 242 is evenly provided with auxiliary fixing grooves 244, which are used to engage and fix the top of the test tube.

[0025] like Figure 4 As shown, the connecting assembly 4 includes a connecting cavity 41, which is opened inside the upper frame 241. A connecting shaft 42 is fixedly connected to the top of the lower frame 242. The top of the connecting shaft 42 is inserted into the connecting cavity 41 and fixedly connected to a connecting ball 43. Supporting springs 44 are uniformly fixedly assembled between the connecting ball 43 and the connecting cavity 41. By setting the supporting springs 44, there is a certain elastic space between the connecting ball 43 and the connecting cavity 41, so that the lower frame 242 and the upper frame 241 can swing relative to each other within a certain range. The upper frame 241 can be connected and fixed to the assembly frame 23, while the lower frame 242 can move with the bottom tray 21 to better mix the sample in the test tube.

[0026] Working principle: When using this device to mix samples, first select the bottom tray 21 and auxiliary fixing frame 24 of the corresponding size according to the size of the test tube. Connect and fix the bottom tray 21 to the top of the action unit of the mixer body 1. Then connect and fix the auxiliary fixing frame 24 to the assembly frame 23. After inserting the test tube into the slot 213, adjust the position of the auxiliary fixing frame 24 by adjusting the position of the assembly frame 23, so that the lower frame 242 of the auxiliary fixing frame 24 provides auxiliary limiting and fixing to the top of the test tube. Then, calibrate the fixing position of the assembly frames 23 on both sides according to the scale 3, so that the assembly frames 23 on both sides are horizontally aligned. Then, turn on the mixer body 1. The action unit inside the mixer body 1 drives the bottom tray 21 to shake, mixing the sample in the test tube. During the shaking, the lower frame 242 can cooperate with the bottom tray 21 to move, limiting and fixing the test tube while also meeting the movement requirements of the bottom tray 21, so that the sample in the test tube can get a more uniform mixing effect.
