Description
Technical field
The utility model is related to a kind of magnetic stirring apparatus more particularly to a kind of anti-scald magnetic stirring apparatus.
Background technology
For the magnetic stirring apparatus in present laboratory by having the function of stirring and heat, the heating surface of blender is all not
Rust steel material, there is good heat conductivility, but under normal conditions after having heated, after closing stirrer source, on heating surface
Still there is very high temperature, if laboratory operation personnel contact heating surface with hand and be easy to cause not according to the operation of regulation
Scald.
Utility model content
The utility model still has very high in order to overcome magnetic stirring apparatus in the prior art after having heated, on heating surface
Temperature, if laboratory operation personnel contact the deficiency that heating surface be easy to cause scald not according to the operation of regulation with hand,
Provide a kind of anti-scald magnetic stirring apparatus.
To achieve the goals above, the utility model uses following technical scheme：
A kind of anti-scald magnetic stirring apparatus, including mixer drive, heating container, heating plate and stirring magnet, it is described
Heating container is supported in the heating plate, and the stirring magnet is held by mixer drive driving setting in the heating
In device, thermoelectric generator is had in the heating plate, the thermoelectric generator includes that there are one hot junction and two cold ends, hot junctions
It is connected respectively by several P-type semiconductors and several N-type semiconductors with two cold ends, is electrically connected between two cold ends
LED warning lamps are connected to, the cold end of the thermoelectric generator is connected with radiator.
By such structure, do not need when additional power supply can make heating plate have surplus heat in the hot junction of thermoelectric generator and cold
End generates temperature difference, and due to the temperature difference in hot junction and cold end, the carrier of P-type semiconductor and N-type semiconductor is from high concentration to low
Concentration is spread, and since P-type semiconductor is different with the diffusion rate of N-type semiconductor carrier, then electricity is formed between two cold ends
Pressure is so that LED warning lamps shine.Radiator can be radiated by way of natural heat dissipation or forced heat radiation.
As a kind of optimal technical scheme of the utility model, the radiator includes the condenser pipe of cycle, described
Condenser pipe is connected with water pump, and the water pump includes check valve, and the check valve is connected with microprocessor, is gone back under the heating plate
Equipped with pressure sensor and temperature sensor, the pressure sensor and temperature sensor are electrically connected with the microprocessor.
After pressure sensor, which measures the heating container in heating plate, to be removed, signal is passed into microprocessor, micro- place
It manages device control check valve to open, condenser pipe leads to recirculated water to temperature sensor cold end forced heat radiation, when temperature sensor measures
Temperature not higher than microprocessor setting preset temperature when, microprocessor control closed check valve.
As a kind of optimal technical scheme of the utility model, thermal conductive silicon is coated between the heating plate and the hot junction
Fat.
The advantageous effect that the utility model is reached compared with prior art is：
When the temperature of heating plate is higher, LED warning lamps shine and play a warning role, and are realized by thermoelectric generator
The luminous function of LED warning lamps, does not need additional power supply；
It is radiated to the cold end of thermoelectric generator by the condensate water circulatory circuit of radiator, while also heating plate is dissipated
Heat so that the temperature of heating plate, which can be dropped rapidly to human body, can touch temperature.
