Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and relates to a milk warmer, in particular to a segmented milk warmer. Background Technique

[0002] Most milk powder manufacturers require warm water at 40°C - 50°C to be used for preparing milk powder to protect the nutritional value of the formula milk from being damaged, and the water temperature should be set within this temperature range during use. The milk warmer can keep the boiled water at a suitable temperature for preparing milk powder, so as to facilitate the preparation of milk powder at any time.

[0003] Traditional milk warmers have functional limitations and cannot adjust the water outlet temperature, which restricts their ability to meet the diverse needs of users under different regions and seasonal changes, and also affects the competitiveness of products in the market. Manually controlling the water temperature and volume is not only time-consuming and laborious, but for novice parents, it is difficult to ensure that the proportion of milk preparation reaches the ideal state each time. In addition, traditional devices may have problems with residual water in the pipeline, resulting in cold water in the pipeline being discharged when the water is first discharged, which will affect the accuracy of the milk temperature and the overall quality of the milk liquid.

[0004] In addition, the instant milk warmers currently on the market usually only provide quantitative water output and adjustable temperature, directly outputting the mixed water when preparing milk, lacking an intelligent segmented milk preparation function. If the water temperature is too low, the milk powder is difficult to dissolve fully, affecting the final milk preparation effect; if the water temperature is too high, additional steps of shaking and cooling are required to reach a suitable temperature for infants to consume, which is not only troublesome but also poses a risk of scalding.
