Opening covers, and volatilization gas discharge outlet (2a) is provided on sealing cover (2)；The heating container (1) be circumscribed with water inlet pipe (3) and
Drainpipe (4), this two water pipes are connected to the inner cavity of heating container (1), it is characterised in that: are set in the heating container (1)
There are electric heater (5) and temperature sensor (6), wherein electric heater (5) is located at heating container (1) bottom, temperature sensor (6)
Positioned at the middle and lower part of heating container (1) side wall, and the detection data of temperature sensor (6) feeds back to the control of electric heater (5)
Device, and control the working condition of electric heater (5)；The outer wall of heating container (1) is equipped with a micro pump (7), should
The water inlet end of micro pump is connected to by an external water inlet pipe (8) with the bottom of heating container (1) inner cavity, micro pump (7)
Water outlet be connected to by outer connected water outlet pipe (9) with the top for heating container (1) inner cavity.
In said structure, volatilization gas discharge outlet (2a) is for discharging volatilization gas.Electric heater (5) be used for water into
Row heating, and temperature sensor (6) detects water temperature, the detection data of temperature sensor (6) feeds back to electric heater (5), thus
Negative-feedback is formed, to make temperature keep constant in the section of setting, and the heating speed of electric heater (5) is fast, high-efficient.
In addition, establishing the external circulation path of water by micro pump (7), increase the mobility of water, also can guarantee that water is uniformly added in this way
Heat.Also, all using mature component, structure is simple, avoids chemical experiment described in ZL2017207359777 well for this case
The room complicated defect of uniform water bath heating device.
Powder-refining with water is splashed in order to prevent, and the inner end of the outer connected water outlet pipe (9) is vertical end, outer connected water outlet pipe (9) inner end
It is discharged mouth down.
Preferably, the water inlet pipe (3) is located at heating container (1) top, drainpipe (4) is located under heating container (1)
Portion.
The utility model has the advantages that the utility model can fast and efficiently heat cold water, and water temperature is made to be maintained at the temperature range of setting
It is interior constant, and uniform distribution of temperature field, moreover it is possible to effectively discharge escaping gas；Meanwhile this case is removed from all using mature component
The chemical laboratory rabbling mechanism of uniform water bath heating device described in ZL2017207359777, eliminates rotation section together
The problem of part seals simplifies structure to reply, reduces manufacture difficulty and cost, is suitable for large-scale promotion and uses.
