Description of drawings
Fig. 1 is electromagnetic-radiation-free superminiature double end magnetic stirring apparatus structure of the present utility model and work schematic diagram.
The specific embodiment
As shown in Figure 1, be electromagnetic-radiation-free superminiature double end magnetic stirring apparatus of the present utility model, mainly constitute by direct current micromotor 1, speed governing element, battery pack, casing etc., wherein, in the cavity volume of metal chassis 11, be installed with two direct current micromotor 1a, 1b, two integrated circuit board 2a, 2b, two potentiometers 6,7, two power switches 8,9, and a battery cavities 10.
Two direct current micromotor 1a, 1b are positioned at the middle part of metal chassis 11, and two power transmission shafts stretch out casing 11, are connected with two stirring-heads 4,5 respectively, drive 4,5 rotations of two stirring-heads, and the end face of two stirring-heads 4,5 is embedded with miniature permanent magnet rod 3a, 3b.Two stirrers 12,13 of two stirring-heads 4,5 and split are supporting.
Two integrated circuit board 2a, 2b lay respectively at two direct current micromotor 1a, the 1b left and right sides, and two outsides about two integrated circuit board 2a, 2b are respectively equipped with two potentiometers 6,7, two power switches 8,9.A plurality of dry cells in the battery cavities 10 are formed battery pack and are each parts power supply.
Two potentiometers, 6,7 knobs and two power switches, 8,9 buttons are fixed on the left and right sides sidewall of casing 11, and the size of current of direct current micromotor 1a, 1b is supplied with in the control of two potentiometers, 6,7 knobs, and then change the rotating speed of direct current micromotor 1a, 1b.Start or cut off the electricity supply with two power switches, 8,9 buttons.
The diameter of two stirring-heads 4,5 is less than 10mm, and distance is about 10mm.
Electromagnetic-radiation-free superminiature double end magnetic stirring apparatus of the present utility model can be made the single head magnetic stirring apparatus as required and use.
Electromagnetic-radiation-free superminiature double end magnetic stirring apparatus of the present utility model has following characteristics:
1, battery pack direct current supply does not have electromagnetic interference.
2, direct current micromotor and speed governing wiring board are installed in the metal chassis, produce the leakage of electromagnetic radiation in the time of can effectively preventing their work.
3, the power supply of two stirring-heads is separately control because stirring-head surface-mounted integrated circuit can consumed power yet when not changeing, no stirring-head can the deenergization save power.
