[0019] Embodiments of the present utility model: Figure 1-Figure 4 As shown, a reagent storage device with a mixing device includes a base 1 and a bottle body 2. The top of the base 1 is plugged into the bottom of the bottle body 2. A rotor driving device is arranged in the base 1. The bottle body 2 contains four chambers 3. Each chamber 3 is equipped with a magnetic rotor 4. Four sets of liquid inlet and outlet components are arranged on the top of the bottle body 2. The four sets of liquid inlet and outlet components are connected to the four chambers 3 respectively.

[0020] The rotor driving device is used to drive the magnetic rotors 4 in the four chambers 3 to rotate, and the magnetic rotors 4 are used to stir the solution to quickly mix the solution to meet the detection requirements. The inlet and outlet liquid components are used to introduce and export the solution into the chamber 3.

[0021] In a specific embodiment, the cross-section of the base 1 and the bottle body 2 are both square, the size of the bottle body 2 is larger than that of the base 1, so that the base 1 can be inserted into the bottom of the bottle body 2, and the inner cavity of the bottle body 2 is divided into four square chambers 3 of exactly the same shape and size by a cross-shaped partition. The four chambers 3 can be respectively loaded with cationic eluent, anionic eluent, regeneration solution and one other solution to meet the test requirements.

[0022] Furthermore, the rotor driving device includes a rotor driving unit, a support frame 5 and a driving motor 6. The support frame 5 is fixed in the base 1. The support frame 5 has four supporting rods. A rotor driving unit is rotatably installed on each supporting rod. The driving motor 6 is fixed at the center position of the bottom plate of the base 1. A driving gear 7 is installed on the output shaft of the driving motor 6. The driving gear 7 is connected to the four rotor driving units at the same time.

[0023] The four ends of the support frame 5 are fixedly connected to the inner wall of the base 1, and a through hole is provided at the center of the support frame 5, through which the output shaft of the drive motor 6 can pass, thereby improving the rotation stability of the output shaft of the drive motor 6. The four rotor drive units are located directly below the four chambers 3, respectively.

[0024] Furthermore, the structures of the four rotor drive units are exactly the same. The rotor drive units include a rotating shaft 8, a turntable 9 and a driven gear 11. The rotating shaft 8 is rotatably mounted on the support rod through a bearing. The turntable 9 is fixedly mounted on the upper end of the rotating shaft 8.

Two magnets 12 are fixedly provided on the top surface of the turntable 9. The two magnets 12 are symmetrically arranged relative to the axis of the turntable 9. The two ends of the magnetic rotor 4 are magnetic. The two ends of the magnetic rotor 4 are attracted to the two magnets 12 on the turntable 9. A ring 13 is formed in the middle position of the magnetic rotor 4.

[0025] The rotating shaft 8, the rotating disk 9 and the driven gear 11 are coaxially arranged, the rotating disk 9 is a circular rotating disk, the magnet 12 is a cylindrical magnet, and the magnet 12 is used to adsorb the two ends of the magnetic rotor 4. The driving gear 7 drives the driven gear 11 to rotate, and the driven gear 11 rotates with the rotating disk 9 through the rotating shaft 8, so that the two magnets 12 rotate with the rotating shaft 8 as the axis, and the magnetic rotor 4 rotates under the action of magnetic force, and the magnetic rotor 4 stirs the solution. The ring 13 is arranged in the middle position of the magnetic rotor 4 to reduce the contact area between the magnetic rotor 4 and the chamber 3, thereby reducing the friction.

[0028] The liquid outlet pipe 16 is arranged on the opposite side to the first liquid inlet pipe 14 and the second liquid inlet pipe 15, so as to prevent the solution from being sucked out by the liquid outlet pipe 16 before being fully stirred. By setting the flow sensor 10, the detection device can conveniently control the speed of sucking the solution. It should be noted that, according to actual needs, a third liquid inlet pipe and a fourth liquid inlet pipe can be added to each chamber 3.
