Description

Technical Field

[0001] The present invention relates to the field of smart homes, and in particular to a method and device for intelligently monitoring and reminding drinking water. Background Art

[0002] Scientific drinking water can prevent and treat cardiovascular and cerebrovascular diseases, indigestion, and constipation; it is beneficial for relieving cough and expectoration, protecting kidney function, anti-aging, preventing cancer and preventing cataracts.

[0003] For the elderly and other groups, due to the decline of their physiological functions, the water content in their bodies will gradually decrease, which often cannot meet the needs of physiological activities. Due to the lack of body fluids, blood flow will be slow, metabolic products will accumulate, and gas exchange will be insufficient, which is extremely detrimental to health and longevity. At the same time, on the one hand, the elderly are reluctant to drink water due to their inconvenience in movement, and on the other hand, the people being cared for are insensitive to the feeling of thirst and gradually develop chronic dehydration. It is worth noting that various organs and their metabolic functions of the elderly are constantly declining. Long-term dislike of drinking water or insufficient drinking of water will accelerate the decline of their organ functions. Therefore, how to study the corresponding drinking water reminder device according to the characteristics of the cared users and realize accurate reminders for the cared users to drink water is a problem that needs to be solved urgently.

[0004] For current drinking reminder devices, the common practice is to install a Bluetooth chip on the drinking device, control the Bluetooth chip through mobile phone software to set the drinking time and frequency, and remind at the specified time.
