Description

Technical Field

[0001] This invention relates to the field of massage and health care equipment technology, specifically to a massage belt with indicator lights and simultaneous abdominal and back massage. Background Technology

[0002] Currently, most massage belts on the market have a simple structure, with the vast majority only featuring a single back massage function. This means they can only provide localized massage to the back and cannot simultaneously massage the abdomen, resulting in a lack of functionality and failing to meet users' needs for simultaneous back and abdominal relaxation. Furthermore, traditional massage belts lack indicator lights, making it impossible to clearly display whether the device is powered on, its operating level, or its malfunction status. This hinders users from quickly assessing the belt's operating status and leads to a poor user experience. Additionally, traditional massage belts often use physical buttons for control, which are inconvenient and difficult for the elderly and people with mobility issues to use.

[0003] In summary, existing massage belts suffer from technical defects such as limited massage positions, lack of operating status indicators, and inconvenient operation. There is an urgent need to develop a new type of massage belt that can simultaneously massage the abdomen and back, has indicator lights, and can be remotely controlled. Summary of the Invention
