A. The bottom of the glass jar cannot be very flat;
B. The electric heating base is not fixedly connected with the glass, so heat conducting materials cannot be used;
C. Glass is a material with general thermal conductivity;
D. In order to prevent the glass pot from bursting due to uneven heating, concave-convex concentric circles are formed on the surface of the electric heating plate.
E. The heat dissipation area of the glass jar is much larger than the heating area;
F due to the limitation of structure and material properties, it is impossible to make the heating power of electric heating plate too large.
Therefore, this milk mixer with split glass pot structure also has the same disadvantages: low electric heating efficiency, very slow water temperature rise (30 degrees 1 hour), unstable water temperature (greatly affected by environmental temperature and air flow), and it is a product with no practical value.
In the latter case, a quick constant temperature milk regulator with a thermostat is usually installed in a quick electric kettle, which can boil water very quickly and adjust the temperature even faster, only taking 2-3 minutes. In addition, this kind of products have high electric heating efficiency and high power, and the water temperature is less affected by environmental temperature and air flow, and the water temperature is stable and accurate.
In addition, the latter integrates the functions of boiling water and constant temperature, which is convenient for milk adjustment.
An An SJ- 1002 milk regulator belongs to the latter, and obtained the national utility model patent.
