Problems solved by technology

But in the actual product, due to the limitation of the production process level, the water flow speed tolerance of the water pump under the same driving voltage is ±20%, and after the user uses the product for several months or years, further changes in the water pump speed attenuation may occur
For the quantitative water outlet module of instant heating products, because the control board cannot know the corresponding relationship between the driving value and water flow speed of each machine, the control software can only use the default driving value-water flow speed curve to calculate the water output, but because The tolerance of the water pump is too large, and the actual characteristic curve of the water pump of each machine may have a large deviation from the default curve, which in turn causes the problem of inaccurate quantitative water output accuracy of the water dispenser
