Description

Technical Field

[0001] The utility model relates to the technical field of water baths, in particular to a bath heating controller. Background Art

[0002] Many of the data to be measured in chemical experiments, such as viscosity, vapor pressure, conductivity, reaction rate constant, etc., are closely related to temperature, which requires the experiment to be carried out at a constant temperature. The commonly used one is a constant temperature bath, which is generally composed of a water tank, a controller, a heater, a circulation pump and a sensor. Among them, the water tank is used to store water and is also the main place for experiments; the controller is a key component used to control the water temperature, which can be adjusted according to different experimental requirements; the heater is a component used to heat water, and the water temperature is controlled by heating the water in the water tank; the circulation pump circulates the water to make the water temperature more uniform; the sensor monitors the water temperature and transmits data to the controller to control the water temperature.

[0003] In the prior art, when measuring the viscosity of the liquid, the rotor of the viscometer is inserted into the liquid for automatic measurement, and the operator does not need to stare at it for a long time. However, the water temperature is controlled by the initial setting. The electric heater stops heating after heating to a predetermined temperature. However, the electric heater fails to heat after being affected by external factors, such as unstable voltage and long-term use. The controller cannot promptly feedback the abnormality to the operator. In addition, the measuring container is placed in the water tank through the top opening of the water tank. Due to the opening design of the water tank, the subsequent water temperature is easily dissipated from above, resulting in large temperature fluctuations, which affects the operation of the heater. Therefore, we propose a bath heating controller to solve the above problems. Utility Model Content

[0023] The outer wall of the annular acrylic plate 3 is fixedly connected with a circular ring 6, and two L-shaped grooves 7 are provided on the outer wall of the circular ring 6. The inner walls of the two L-shaped grooves 7 are slidably connected with rectangular blocks 8. The inner wall of the elastic rubber ring 5 is slidably connected with a container 9. There is a certain friction between the elastic rubber ring 5 and the container 9 to prevent the container from tipping over and rotating. The bottom of the container 9 is in contact with the bottom inner wall of the mesh frame 4. One ends of the two rectangular blocks 8 are fixedly connected to the outer wall of the water bath 2, and an insulating layer 15 is provided inside the water bath 2.

[0024] The water bath 2 is provided with an alarm mechanism, which includes a main control module 10.

An assembly groove is provided on the outer wall of the water bath 2, and the inner wall of the assembly groove is fixedly connected with the main control module 10. The output end of the main control module 10 is electrically connected to a temperature control module, a power management module and a wireless communication module through a cable.
