Description

Technical Field

[0001] The utility model relates to the technical field of magnetic stirring equipment, in particular to a constant temperature magnetic stirrer structure. Background Art

[0002] A magnetic stirrer is a laboratory instrument used for liquid mixing. It is mainly used to stir or heat and stir low-viscosity liquids or solid-liquid mixtures at the same time. The temperature of the stirred liquid is kept stable through a constant temperature system, and a rotational force is generated through a magnetic transmission device, so that the stirring rod can quickly and evenly stir the mixed liquid in the container. This structural design can ensure that chemical and biological experiments and other work requiring stirring can be carried out efficiently under constant temperature conditions.

[0003] The "magnetic stirrer" described in patent application number "CN202320134469.9" has a technical solution in which the position of the fixing clamp can be quickly adjusted through a lifting frame and a telescopic frame, thereby improving the flexibility and convenience of the container when used. The use of an arc table can increase the contact area between the stirrer body and the round-bottom container, thereby improving the working efficiency of the stirrer body.

[0004] However, the applicant believes that although the existing magnetic stirring structure is convenient for quickly adjusting the position of the fixing clamp during stirring, the stirring effect of the magnetic stirrer on the liquid in the cup is not obvious when it is first used for stirring. When the stirring power is too high and the liquid is continuously stirred, the liquid in the cup is easy to overflow from the cup.

[0005] For this purpose, we provide a constant temperature magnetic stirrer structure. Utility Model Content

[0006] The main purpose of the utility model is to provide a constant temperature magnetic stirrer structure, which can effectively solve the problem proposed in the background technology that the magnetic stirrer has no obvious stirring effect on the liquid in the cup when it is first used for stirring, and when the stirring power is too high and the liquid is continuously stirred, the liquid in the cup is easy to overflow from the cup.

[0014] Beneficial Effects

[0015] Compared with the prior art, the utility model has the following beneficial effects: the constant temperature magnetic stirrer structure is equipped with devices such as a pressure sensor, an elastic clamp and a movable frame.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 5As shown, in this embodiment, a constant temperature magnetic stirrer structure includes a mounting plate 6, a slide groove is provided on one side of the mounting plate 6, a telescopic rod 7 is embedded and installed on the inner side of the slide groove, a mobile frame 8 is embedded and installed above the telescopic rod 7, a plurality of connecting shafts 9 are embedded and installed on the inner side of the mobile frame 8, a handle 10 is fixedly installed on the upper side of the mobile frame 8, a cup holder 11 is provided on one side of the handle 10, and the cup holder 11 is embedded and connected with the mobile frame 8, an elastic clamp 1302 is fixedly installed on one side of the cup holder 11, a cup clamp 13 is provided on one side of the elastic clamp 1302, and the cup clamp 13 is movably connected with the cup holder 11 through the elastic clamp 1302, a pressure sensor 1301 is embedded and installed on the inner side of the cup clamp 13, the cup clamp 13 is clamped on both sides of the upper side of the stirring cup 1101 through the elastic clamp 1302, and the pressure sensor 1301 is connected with the magnetic stirrer 1 by signal.

[0025] Specifically, through this arrangement, when the liquid in the mixing cup 1101 is stirred, the cup clamp 13 is used to fit and clamp the upper outer side of the mixing cup 1101 to improve the stability during stirring. When the stirring power of the liquid in the mixing cup 1101 is high, continuous stirring will cause the liquid to fit the inner wall of the mixing cup 1101 and rise. At this time, the impact force of the eddy current generated by the rotation of the liquid on the inner wall of the mixing cup 1101 will also increase accordingly and be monitored by the pressure sensor 1301. Since the cup clamp 13 is attached to the upper side of the mixing cup 1101 through the elastic clamp 1302, the data information is transmitted to the control processor in the magnetic stirrer 1 through the pressure sensor 1301, and the pressure sensor 1301 is used to detect the impact of the eddy current on the inner wall of the mixing cup 1101. The control processor in the magnetic mixer 1 controls the magnetic rod in the magnetic mixer 1 to reduce the power, and then reduces the stirring power of the magnetic rod 1102 through the magnetic rod, thereby avoiding the situation where the magnetic rod 1102 continues to stir under the initial power that is too high in order to improve the stirring effect, causing the liquid in the stirring cup 1101 to overflow. At the same time, the telescopic rod 7 moves on the mounting plate 6 and the mobile frame 8 to adjust the placement angle and direction of the stirring cup 1101, and the telescopic rod 7 is used to adjust the placement height of the stirring cup 1101. Secondly, the handle 10 is used to adjust the angle, direction and height of the telescopic rod 7 and the mobile frame 8, so as to remove or put in the stirring cup 1101 from the magnetic stirring device for use.

[0026] like Figure 1 - Figure 5As shown, in this embodiment, a magnetic stirrer 1 is fixedly installed on one side of a mounting plate 6, a display screen 2 is embedded and installed on one side of the magnetic stirrer 1, a control button 4 is provided on one side of the display screen 2, and the control button 4 is connected to the magnetic stirrer 1 in telecommunication, control knobs 3 are symmetrically provided on both sides of the magnetic stirrer 1, and the control knobs 3 are connected to the magnetic stirrer 1 in telecommunication, a magnetic stirring table 5 is fixedly installed above the magnetic stirrer 1, a magnetic rod and a heating coil are provided on the inner side of the magnetic stirring table 5, and the magnetic rod and the heating coil are connected to the magnetic stirrer 1 in telecommunication;

[0027] Specifically, through this arrangement, the telescopic rod 7, the movable rack 8 and the cup rack 11 are installed and used through the mounting plate 6. When the magnetic mixer 1 is used, the device data and other information are displayed through the display screen 2, and the operation of the magnetic rod and the heating coil and other equipment in the magnetic mixer 1 are controlled by the control knob 3 and the control button 4. Secondly, the tray 14 is moved to the center position of the magnetic stirring table 5 to facilitate the constant temperature magnetic stirring of the liquid in the stirring cup 1101.

[0028] like Figure 1 - Figure 5 As shown, in this embodiment, a fixing rod 12 is embedded and installed on one side of the cup holder 11, and the fixing rod 12 is clamped on one side of the movable frame 8 through the cup holder 11, and a tray 14 is fixedly installed below the cup holder 11, and a stirring cup 1101 is provided above the tray 14, and a magnetic rod 1102 is provided on the inner side of the stirring cup 1101, and the magnetic rod 1102 is magnetically attracted to the magnetic rod on the inner side of the magnetic stirring table 5, and the tray 14 is electromagnetically inductively arranged with the heating coil in the magnetic stirring table 5;

[0029] Specifically, through this arrangement, when in use, the cup holder 11 is installed on the top of the mobile frame 8 through the fixing rod 12, and the stirring cup 1101 is placed on the tray 14. At the same time, electromagnetic induction is performed between the tray 14 and the heating coil, and then the stirring cup 1101 on the tray 14 is heated at a constant temperature. Secondly, the magnetic rod operates in the magnetic stirring table 5, and then the liquid in the stirring cup 1101 is magnetically stirred by the magnetic rod 1102 and the magnetic rod magnetic attraction setting.

[0030] It should be noted that when using the utility model as a constant temperature magnetic stirrer structure, firstly, the telescopic rod 7, the mobile frame 8 and the cup rack 11 are installed and used through the mounting plate 6, and the cup rack 11 is installed on the top of the mobile frame 8 through the fixing rod 12. When the magnetic stirrer 1 is used, the device data and other information are displayed on the display screen 2, and the operation of the magnetic rod and the heating coil and other equipment in the magnetic stirrer 1 is controlled by the control knob 3 and the control button 4. Secondly, the tray 14 is moved to the center position of the magnetic stirring table 5 to facilitate the constant temperature magnetic stirring of the liquid in the stirring cup 1101. When the stirring power of the liquid in the stirring cup 1101 is high, the continuous stirring will make the liquid adhere to the inner wall of the stirring cup 1101 and rise. At this time, the vortex generated by the rotation of the liquid on the inner wall of the stirring cup 1101 will also increase accordingly, and The pressure sensor 1301 is used for monitoring, and the data information is transmitted to the control processor in the magnetic mixer 1 through the pressure sensor 1301. The control processor in the magnetic mixer 1 controls the magnetic rod in the magnetic mixer 1 to reduce the power, and then reduces the stirring power of the magnetic rod 1102 through the magnetic rod, so as to avoid the situation that the magnetic rod 1102 continues to stir under the initial excessive power to improve the stirring effect, causing the liquid in the stirring cup 1101 to overflow. At the same time, the telescopic rod 7 moves on the mounting plate 6 and the mobile frame 8 to adjust the placement angle and orientation of the stirring cup 1101, and the telescopic rod 7 is used to adjust the placement height of the stirring cup 1101. Secondly, the handle 10 is used to adjust the angle, orientation and height of the telescopic rod 7 and the mobile frame 8, so as to remove or put in the stirring cup 1101 from the magnetic stirring device for use.
