[0002] Water baths usually refer to constant temperature water baths and water bath heating tanks used in laboratories. They are mainly used for distillation, drying, concentration and temperature soaking of chemicals or biological products in laboratories. They can also be used for constant temperature heating and various temperature tests. They are indispensable tools in the fields of biology, genetics, viruses, aquaculture, environmental protection, medicine, health, laboratories, analysis rooms, and education and scientific research.

[0003] At present, there are serious safety hazards in the water baths on the market. They lack the low liquid level warning function, which may be easily ignored during the heating process, resulting in the evaporation of water in the water bath and dry burning. The water bath drying up may cause a fire, posing a serious threat to the personal safety of experimenters and laboratory equipment. It is very important to ensure the safe use of the water bath and avoid the dry phenomenon. In addition, the intelligence of the water bath is also seriously insufficient, far behind other intelligent laboratory equipment, and cannot achieve remote control, automatic control, etc., which affects the efficiency of the experiment.

[0016] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings. Example 1

[0017] Reference Figure 1-Figure 2 , an automatic early warning and water replenishing device for a water bath pot, comprising a rubber waterproof shell and a control board 3, a surface of the control board 3 is provided with a water level early warning unit 4, an automatic water replenishing unit 5 and a remote control unit 6 in sequence from top to bottom, a central processing unit 201 (STM32F103 processor) is provided inside the control board 3, and the central processing unit 201 is respectively connected to the water level early warning unit 4, the automatic water replenishing unit 5 and the remote control unit 6 by signal.

[0018] The water level warning unit 4 includes an ultrasonic water level sensor 202 and an alarm 212 .

[0019] The automatic water replenishment unit 5 comprises a solenoid valve 203 , which is arranged on the water inlet pipe of the water bath 1 . The solenoid valve 203 is connected to the central processor 201 by signal, and the water source is tap water.
