Description

Technical Field

[0001] The utility model relates to the technical field of magnetic coupling stirrers, in particular to a small magnetic coupling stirrer. Background Art

[0002] A magnetic coupling stirrer is an instrument that utilizes the property of magnetic materials that like poles repel each other. It drives the magnetic stirring bar to rotate by constantly changing the polarity of the two ends of the base, and then relies on the rotation of the magnetic stirring bar to drive the sample to rotate, so that the sample is evenly mixed. Magnetic coupling stirrer is a modern word, a special term, which refers to liquids with low viscosity. However, the existing magnetic coupling stirrers have some shortcomings, such as:

[0003] Publication No.: CN204074008U, the reactor magnetic coupling agitator, the device is reasonably designed, provides a new type of magnetic coupling agitator for the reactor, and improves the sealing strength. However, in actual use, since the stator, rotor and other mechanisms of the device are fixed by a fixed sleeve, the rotating sleeve of the device may be filled with water, which may affect the normal use of the agitator;

[0004] So we proposed a small magnetic coupling stirrer to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a small magnetic coupling agitator to solve the problem raised in the above background technology that the stators, rotors and other mechanisms of most magnetic coupling agitators on the market are fixed by a fixing sleeve, which may cause water to enter the rotating sleeve of the equipment and may affect the normal use of the agitator.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a small magnetic coupling agitator, comprising a driving motor and a top shell arranged on the top of the driving motor, a transmission shaft connected to the top of the driving motor, and the transmission shaft passes through the top shell, and a first rotor is connected to the top of the transmission shaft, a second rotor is arranged on the outside of the first rotor, and a device shell is connected to the outside of the second rotor, and a first stirring blade is connected to the top of the device shell, a snap head is connected to the top of the device shell, and a second stirring blade is connected to the top of the snap head, and the second stirring blade is snap-connected to the snap head.

[0007] By leaving a gap between the first rotor and the second rotor, the transmission shaft, the first rotor and other equipment can be prevented from being directly connected to the second rotor, the first stirring blade and other equipment, which makes it more convenient for the user to protect the first rotor and the second rotor, thereby preventing water from entering the agitator and increasing the protectiveness of the equipment.

[0008] As a preferred technical solution of the utility model, a protective shell is provided on the outer side of the driving motor, and the protective shell is fixedly connected to the driving motor, and the protective shell is fixedly connected to the top shell.

[0009] By adopting the above technical solution, a protective shell can be arranged on the outside of the driving motor, and the protective shell is connected to the top shell, so that when the device is working, the driving motor can be protected by the top shell, thereby increasing the protectiveness of the device.

[0010] As an optimal technical solution of the utility model, a container is provided on the top of the top shell, and a first air gap plate is connected to the bottom of the container, the first air gap plate is located between the first rotor and the second rotor, and a positioning shaft is connected to the container, and the positioning shaft limits the rotating shaft, and a feed port is connected to the top of the container.

[0011] The above technical solution can connect the first air gap plate to the container, and the first air gap plate can separate the first rotor from the second rotor. When the container is connected to the agitator, there is no need to open a hole at the bottom. It is only necessary to fix the first rotor inside the first air gap plate. When the driving motor drives the first rotor to rotate, due to magnetic force, the first rotor will also drive the second rotor to rotate, thereby making the agitator work.

[0012] As a preferred technical solution of the present utility model, the top shell is a concave structure, and the transmission shaft passes through the bottom of the top shell and is rotationally connected to the drive motor.

[0013] As a preferred technical solution of the utility model, an air gap is left between the first rotor and the second rotor, and the first rotor and the second rotor are coupled by magnetic force.

[0014] The above technical solution enables the first rotor to directly drive the second rotor to rotate without contacting the second rotor when driving the second rotor to rotate, thereby increasing the coupling property of the device.

[0015] As a preferred technical solution of the present invention, both the first rotor and the second rotor are magnetic, and the first rotor can fit with the second rotor through magnetic force.

[0016] Compared with the prior art, the beneficial effect of the utility model is that by leaving a gap between the first rotor and the second rotor, the transmission shaft, the first rotor and other equipment can be not directly connected to the second rotor, the first stirring blade and other equipment, which makes it more convenient for the user to protect the first rotor and the second rotor, thereby preventing water from entering the agitator and increasing the protectiveness of the equipment.

[0017] By connecting the first air gap plate to the container and separating the first rotor from the second rotor, it is possible to connect the container to the stirrer without opening a hole at the bottom, and only need to fix the first rotor inside the first air gap plate, so that when the driving motor drives the first rotor to rotate, due to magnetic force, the first rotor will also drive the second rotor to rotate, so that the stirrer works;

[0018] Furthermore, by providing a protective shell on the outside of the driving motor and connecting the protective shell to the top shell, the driving motor can be protected by the top shell when the device is working, thereby increasing the protectiveness of the device.
