Preferably, described magnetic stirring apparatus comprises a U-shaped magnet, and described U-shaped magnet two free end is equipped with stirrer two ends respectively.
Preferably, the distance of described U-shaped magnet two free end is identical with described stirrer length.
Preferably, described stirrer length and the described diameter compatible covering lower end that stirs close.
Preferably, described housing is also provided with a temperature display and temperature regulating key, described temperature display is connected with described temperature sensor, and described temperature regulating key is connected with described heating plate.
Preferably, the described cover that stirs comprises a cover body and one and the cover cap of described cover body threaded engagement, and described cover body is provided with symmetrical two fixed handles, and described cover cap is provided with one and screws bar.
Compared with prior art, the beneficial effects of the utility model comprise: by being embedded a heating plate in real time to the heating of stirring cover on housing, arrange bottom heating mantles simultaneously and detect groove so that the monitoring of temperature, in in stirring cover, liquid constantly stirs, namely liquid has harmony with stirring cover temperature, the temperature being stirred cover bottom by test is determined to stir fluid temperature in cover, and its accuracy rate is higher.
Accompanying drawing explanation
Fig. 1 is the syndeton schematic diagram of magnetic stirring apparatus of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1 of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment of the present utility model provides a kind of magnetic stirring apparatus, as shown in Figure 1 and Figure 2, comprise heating plate 2, the stirring cover 3, be positioned on described heating plate 2 that a magnetic stirring apparatus 6, be located in described receiving cavity 101 of the housing 1, with receiving cavity 101 is embedded at described housing 1 upper surface and be located at the stirrer 4 stirred in cover 3; The temperature sensor 5 that one has detection probe 501 is provided with in described receiving cavity 101, described heating plate 2 is provided with a through hole 201, be provided with a detection groove 301 matched with described through hole 201 bottom described stirring cover 3, described detection probe 501 is passed described through hole 201 and is placed in described detection groove 301.
The present embodiment heats stirring cover 3 in real time by being embedded a heating plate 2 on housing, arrange bottom heating mantles 3 simultaneously and detect groove 301 so that the monitoring of temperature, in in stirring cover 3, liquid constantly stirs, namely liquid has harmony with stirring cover 3 temperature, determine to stir fluid temperature in cover 3 by the test temperature stirred bottom cover 3, its accuracy rate is higher.Wherein, in order to improve accuracy, by improving the thermal conductivity stirring cover 3, reduce the temperature difference stirring cover 3 and the liquid in it.
Due to magnetic stirring apparatus mainly through repulsive force and attraction alternately realize stir, and the size of repulsive force and attraction has larger impact for stirring, therefore the magnetic stirring apparatus 6 of the present embodiment comprises a U-shaped magnet 601, described U-shaped magnet 601 liang of free ends are equipped with stirrer 4 two ends respectively, make stirrer 4 liang of free ends relatively closer to U-shaped magnet 601 liang of free ends, strengthen the active force between stirrer 4 and U-shaped magnet 601.Concrete, the distance of described U-shaped magnet 601 liang of free ends is set to identical with described stirrer 4 length by the present embodiment, thus ensures to have maximum active force between stirrer 4 and U-shaped magnet 601.And in order to ensure that stirrer 4 only rotates in stirring cover 3, reducing the relative disPlacement motion that stirrer 4 does other, the diameter compatible of described stirrer 4 length and described stirring cover 3 lower end closes.
The housing 1 of the present embodiment is also provided with a temperature display 7 and temperature regulating key 8, described temperature display 7 is connected with described temperature sensor 5, described temperature regulating key 8 is connected with described heating plate 2, by the temperature value that the accurate displays temperature sensor 5 of temperature display 7 detects, and temperature adjustment buttons side 8 is for regulating the heating-up temperature value of heating plate 2.It should be noted that, the present embodiment also can be arranged and a heating-up temperature display screen, the temperature for needing heater plate of this heating-up temperature display screen display, and the temperature being hot plate heating regulating button to regulate, it is not identical with the temperature of Temperature displaying screen display, Temperature displaying screen display be stir cover bottom and stir the actual temperature of liquid in cover, owing to adopting the display of heating-up temperature display screen to need the temperature of heating to be the conventional means of this area, therefore not to repeat here for the present embodiment.
Stir in cover 3 whipping process and can cause liquid splash, therefore the described stirring cover 3 of the present embodiment comprises a cover body 302 and one and the cover cap 303 of described cover body 302 threaded engagement, relatively large owing to stirring cover 3 volume, cover cap 303 is tightened on cover body 302 by inconvenience, therefore described cover body 302 is provided with symmetrical two fixed handles 304, described cover cap 303 is provided with one and screws bar 305, be convenient to pick and place stirring cover 3 by arranging two fixed handle 304 1 aspects, when screwing cover cap 303 on the other hand, by fixed handle 304, cover body 302 can be fixed by a hand, cover cap 303 is tightened on cover body 302 by the bar 305 that screws on cover cap 303 by another hand.
The above detailed description of the invention of the present utility model, does not form the restriction to the utility model protection domain.Any various other made according to technical conceive of the present utility model change and distortion accordingly, all should be included in the protection domain of the utility model claim.
