[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a mixing device for a fully automated chemiluminescence analyzer, comprising a body 1, a cover plate 2 at the top of the body 1, a premixing mechanism at the bottom of the inner wall of the body 1, a bracket 4 detachably mounted on the top surface of the body 1 via bolts 5, a threaded groove on the surface of the body 1, the bolts 5 being threadedly connected to the inner wall of the threaded groove of the body 1, a mounting hole on the surface of the bracket 4, the bolts 5 contacting the inner wall of the mounting hole of the bracket 4, and the bracket 4 being fixed to the surface of the body 1 by rotating the bolts 5 with a special tool, thereby supporting and fixing the connecting plate 8, allowing the vibration mechanism 15 to vibrate and mix the reagent kit after reagent injection, a positioning groove on the surface of the body 1, the outer wall of the bracket 4 contacting the inner wall of the positioning groove, and the mounting position of the bracket 4 being positioned and installed through the positioning groove.

[0033] Reference Figure 2 and Figure 4 A connecting seat 6 is detachably mounted on the surface of the bracket 4 via a limiting component 7. A rotating block 12 is rotatably connected to the top of the outer wall of the connecting seat 6, and a threaded rod 13 is rotatably connected to the inner left wall of the connecting seat 6. A slider 14 is threadedly connected to the surface of the threaded rod 13. The rotating block 12 is fixedly connected to the rotation center axis of the threaded rod 13. The inner wall of the slider 14 has an internal thread groove that fits the threaded rod 13. The rotation of the rotating block 12 can drive the threaded rod 13 to rotate, thereby allowing the slider 14 to move up and down on its surface, thereby driving the connecting plate 8 to move up and down, thus causing its bottom end to vibrate. The distance between the mechanism 15 and the reagent kit is adjusted to regulate the vibration frequency, which can be adjusted according to the viscosity of different reagents added. The slider 14 is slidably connected to the inner left side of the connecting seat 6. The outer wall of the slider 14 is fixedly connected to the connecting plate 8. The bottom of the outer wall of the connecting plate 8 is provided with a vibration mechanism 15. The vibration mechanism 15 is an existing technology and adopts an electromagnetic type. Through its non-contact vibration with the reagent kit, it avoids cross-contamination between reagents. At the same time, multiple sets of vibration mechanisms 15 are provided, so that when the placement plate 3 rotates, it can simultaneously vibrate and mix multiple sets of reagents, thereby improving its mixing efficiency.

[0034] Reference Figure 3The premixing mechanism includes a motor 9, the output shaft of which is fixedly connected to a rotating seat 16. A rotating column 11 is slidably connected to the inner wall of the rotating seat 16. A protrusion 17 is fixedly connected to the outer wall of the bottom end of the rotating column 11. A placement tray 3 is fixedly connected to the top of the outer wall of the rotating column 11. The surface of the placement tray 3 has multiple sets of reagent placement slots, which can be used for cleaning and dispensing reagent kits. A protruding rod 18 is fixedly connected to the outer wall of the bottom end of the placement tray 3. An arc-shaped seat 19 is fixedly connected to the bottom end of the inner wall of the machine body 1. The arc-shaped seat 19 is wavy and only one-third the size of the outer arc surface of the placement tray 3. The motor 9 is fixedly connected to the bottom end of the inner wall of the machine body 1. A vertical groove is formed on the surface of the rotating seat 16. The protrusion 17 is slidably connected to the inner wall of the vertical groove of the rotating seat 16. The bottom end of the rotating seat 16 has a vertical groove, which allows the protrusion 17 to move up and down only within the vertical groove of the rotating seat 16. When the rotating seat 16 rotates, it drives the protrusion 17 to rotate synchronously, and also drives the rotating column 11 to rotate. This allows the placement tray 3 to stop during the multiple processes of cleaning, liquid injection, and liquid mixing. The surface of the machine body 1 has an installation groove. The outer wall of the placement tray 3 contacts the inner wall of the installation groove, and the outer wall of the protrusion 18 contacts the surface of the arc-shaped seat 19. The contact between the two allows the reagent kit, after being vibrated and mixed by the vibration mechanism 15, to be pre-contacted by the protrusion 18 and driven to move up and down, thereby performing preliminary mixing of the liquid in the reagent kit and improving its mixing efficiency.

[0035] Reference Figure 4 The limiting component 7 includes a wedge 71, which is elastically connected to the inner wall of the bottom of the connecting seat 6 via a limiting spring 72. One end of the limiting spring 72 is fixedly connected to the outer wall of the wedge 71, and the other end is fixedly connected to the inner wall of the right side of the connecting seat 6. The function of the limiting spring 72 is to automatically reset the position of the wedge 71 after it is squeezed and manually moved. The wedge 71 is slidably connected to the inner wall of the right side of the connecting seat 6. The surface of the bracket 4 is provided with a slot. The bottom end of the outer wall of the connecting seat 6 contacts the inner wall of the slot. The side wall of the slot of the bracket 4 is provided with a slot. The bottom end of the outer wall of the wedge 71 is engaged with the inner wall of the slot. The engagement between the two can quickly fix the position of the connecting seat 6 after it is fixed to the vibration mechanism 15. When the vibration mechanism 15 is damaged, the connecting seat 6 can be disassembled without using special tools to remove the bolts 5.

[0036] Working principle: When installing the connecting seat 6, align the bottom of the outer wall of the connecting seat 6 with the slot of the bracket 4 and insert it. The inclined surface of the bottom end of the wedge 71 is squeezed, overcoming the elastic force of the limiting spring 72 and moving into the connecting seat 6. After the connecting seat 6 is inserted into place, the wedge 71 automatically resets under the action of the limiting spring 72, and its bottom end is inserted into the slot on the side wall of the slot of the bracket 4, quickly fixing the connecting seat 6 as a whole, thereby fixing the vibration mechanism 15. When the vibration mechanism 15 is damaged and needs to be disassembled, manually move the wedge 71 to disengage it from the slot, and the connecting seat 6 can be disassembled as a whole without removing the bolt 5, making the operation simple.

[0037] Simultaneously, motor 9 is started, which drives rotating seat 16 to rotate. When rotating seat 16 rotates, protrusion 17 rotates synchronously in vertical groove. Since protrusion 17 is fixed to rotating column 11, it drives rotating column 11 and placement tray 3 to rotate. When placement tray 3 rotates, the reagent kit on it undergoes cleaning, liquid injection and other processes in sequence. After liquid injection is completed, placement tray 3 continues to rotate, and protrusion 18 contacts the surface of arc seat 19. Due to the waveform structure of arc seat 19, when protrusion 18 contacts arc seat 19, it will drive placement tray 3 to move up and down, perform preliminary mixing of liquid in reagent kit, and improve the efficiency of subsequent vibration mixing.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
