DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1-Figure 5 The hot and cold integrated magnetic stirrer comprises a magnetic base 1, a moving frame 3 is arranged above the magnetic base 1, a moving component for adjusting the up and down position of the moving frame 3 is arranged on the magnetic base 1, a plurality of stirring rods 301 are connected to the lower end of the moving frame 3 in a circular equidistant rotation, a magnetic rotor 303 is arranged at the lower end of the stirring rod 301, a heating plate 105 matching the position of the stirring rod 301 is arranged on the magnetic base 1, a temperature monitoring head 103 is arranged on one side of the heating plate 105, a temperature display screen 101 and a temperature controller 102 are arranged on the magnetic base 1, the temperature display screen 101 and the temperature monitoring head 103 are electrically connected, and the temperature controller 102 is electrically connected to the heating plate 105;

[0023] The moving assembly includes a support plate 2, which is located above the magnetic base 1. The support plate 2 is connected to the magnetic base 1 through symmetrically arranged limit rods 201. The moving frame 3 is slidably connected to the limit rods 201. A screw rod 401 is arranged between the two limit rods 201. The screw rod 401 is rotatably connected to the support plate 2 and the magnetic base 1. A placement cavity is arranged in the magnetic base 1, and a motor 4 is arranged in the placement cavity. The output end of the motor 4 is fixedly connected to the screw rod 401, and the moving frame 3 is threadedly connected to the screw rod 401.

[0024] Among them Figure 1 As shown, the temperature display screen 101 and the temperature controller 102 are respectively provided with multiple groups, and the temperature display screen 101 and the temperature controller 102 in each group are respectively electrically connected with two of the temperature detection monitoring heads 103 and the heating plate 105 used in conjunction therewith. When it is necessary to conduct an experiment on the mixed solution in the experimental bottle, the experimental bottle is first placed on the heating plate 105, and then the temperature of each heating plate 105 is controlled by multiple temperature controllers 102, and the temperature monitoring head 103 displays the real-time temperature of the experimental bottle on the corresponding temperature display screen 101. When all the experimental bottles reach the conditional temperature, the motor 4 works, and the screw rod 401 rotates The movable rack 3 is moved downward to abut against the experimental bottle. At this time, the magnetic base 1 and the magnetic rotor 303 at the lower end of the stirring rod 301 generate a magnetic field, so that the magnetic rotor 303 drives the stirring rod 301 to rotate to fully stir the mixed solution in the experimental bottle. After the experiment is over, the heating plate 105 is turned off, and the motor 4 is allowed to work. The screw rod 401 rotates to drive the movable rack 3 to move upward, so that the experimental bottle loses the clamping effect of the movable rack 3. After the experimental bottle is cooled, the experimental bottle can be taken away. Compared with the existing magnetic stirrer, it can meet the needs of conducting experiments with multiple different reaction conditions on the same device at the same time, effectively speeding up the research and development time, saving labor costs, and improving efficiency.

[0025] Embodiment 2:

[0026] Reference Figure 1-Figure 5 The hot and cold integrated magnetic stirrer is basically the same as Example 1. Furthermore, a placement groove matching the position of the stirring rod 301 is provided on the magnetic base 1, and the heating plate 105 is located in the placement groove. Through the placement groove, the experimental bottle can be placed in the corresponding position more accurately and quickly, which is convenient for better experimental testing.

[0027] An air bag 104 is arranged in the placement groove to prevent the experimental bottle from directly contacting the magnetic base 1, thereby protecting the experimental bottle placed in the placement groove and preventing the experimental bottle from being damaged and affecting the progress of the experiment.

[0028] A protective pad 302 is provided on the lower surface of the mobile frame 3 near the stirring rod 301. When the mobile frame 3 descends and contacts the experimental bottle, the protective pad 302 can effectively prevent the mobile frame 3 from squeezing the experimental bottle too much and causing damage to the experimental bottle.

[0029] The protective pad 302 is detachably connected to the movable frame 3 by Velcro, so that the protective pad 302 is easy to replace.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
