Description

Technical Field

[0001] The utility model relates to the field of water bath pots, and particularly relates to a constant temperature water bath pot. Background Art

[0002] A water bath pot is a commonly used constant temperature device in laboratories. The liquid medium of the water bath pot is water, and the boiling point temperature is usually 100 degrees Celsius. When boiling water under standard conditions, no matter how large the fire is and how long the time is, as long as there is still water boiling, its temperature must be 100 degrees. In this way, heating with a water bath pot can control a constant temperature. The water bath pot is mainly applicable to laboratories and laboratories of major and medium-sized colleges and universities, scientific research enterprises and institutions. The digital display electronic constant temperature water bath pot is widely used for drying, concentration, distillation, impregnation of chemical reagents, impregnation of drugs and biological products, and can also be used for water bath constant temperature heating and other temperature tests. It is an essential tool for biological, genetic, virus, aquatic product, environmental protection, medicine, health, biochemical laboratory, and analysis room education and scientific research.

[0003] During the use of the water bath pot, continuous heating is required to maintain a constant temperature state, which also leads to the evaporation of water. Water needs to be added to the pot during use. The existing water bath pot has a simple structure, and the conventional water addition operation is manual. If the water is not added in time, it is easy to cause the pot to dry out, which affects the use and may cause damage to the water bath pot. Therefore, a constant temperature water bath pot with an automatic water addition function is proposed here to solve the above problems. Summary of the Invention

[0032] The working principle of this specific implementation is:

[0033] First, put an appropriate amount of water into the interior of the pot body 102. Generally, the water level reaches two-thirds of the pot body 102. Control the ring-shaped heating tube 301 to generate heat through the controller 101. After heating to an appropriate temperature, place the carrier of the experimental object and the experimental object. When the water in the pot body 102 evaporates and the water level drops to about one-half of the pot body 102, the second float ball valve 801 senses and opens the valve to add water to the standby water tank 3. At the same time, the water level in the standby water tank 3 drops, and the first float ball valve 406 senses and opens the valve to add water to the standby water tank 3. The water introduced through the water inlet pipe 4 is filtered by the coarse filter stones 403, fine filter stones 404, and filter cotton 405 in the filter cartridge 401 to remove insoluble impurities and waste, and then flows into the standby water tank 3 for heating. The automatic water addition process is repeated in this way.
