[0002] In laboratory analysis and testing, whether testing water quality, soil, or mineral samples, waterbath evaporation of liquid samples is often required. Examples include NY / T1121.16-2006 Soil Testing, Part 16: Determination of Total Water-Soluble Salts in Soil, and GBT5750.4-2023 Standard Methods for the Examination of Drinking Water, Part 4: Determination of Total Dissolved Solids in Sensory and Physical Properties. Current standard methods all utilize waterbaths. Waterbaths are primarily used in the laboratory for distillation, drying, concentration, and soaking of chemicals or biological products. They can also be used for constant temperature heating and other temperature testing. They are essential tools in biology, genetics, virology, aquaculture, environmental protection, medicine, health, laboratories, analytical labs, and educational research. The continuous advancement of modern waterbath heating equipment and technology has led to the emergence of a variety of advanced waterbaths. Waterbaths have become an indispensable piece of equipment in laboratories and industry.

When the water level in the water storage box is high, the 4K power device is activated, connecting V+ and VC+ to activate the micro water pump. When the water level in the water storage box drops to a low level, the 4K pin is powered off, and the micro water pump stops. This prevents the micro water pump from burning out due to no-load operation.

[0042] The use method and advantages of the present invention: When the high-efficiency parallel evaporation device is in operation, the working process is as follows: like Figures 1 to 13 As shown, first set the operating parameters on the touch screen intelligent controller 15 (or mobile phone interface). Adjust the iris mechanism 6 so that its aperture matches the diameter of the evaporating dish. Press the start button to start the system. The heating plate 7 is powered on to heat the chamber, and the circulating fan 8 operates to achieve a more uniform temperature within the evaporation chamber. When the temperature reaches a certain level, the high-temperature air pump 10 starts. Simultaneously, the temperature and humidity sensor 16 transmits the temperature and humidity values ​​of the evaporation chamber to the touch screen intelligent controller (or computer, tablet, or mobile phone) for monitoring. The high-temperature air pump conveys the steam in the evaporation chamber to the electronic condenser. After condensation, the gaseous portion is discharged into the waste liquid tank. The condensed water flows through the overflow port into the water storage box. When the water level in the water storage box rises to the upper limit of the water level sensor 55, the water pump starts to discharge the water into the waste liquid tank. When the water level drops to the lower limit of the water level sensor 55, the water pump stops. This cycle repeats until the sample evaporation meets the standard value and an alarm sound is issued.
