1, key damage: long-term use or frequent pressing may cause key damage or wear, which may lead to key skipping.

2. Entry of liquid: If liquid, such as water or other liquids, enters the key part of the incubator, it may lead to poor contact of the key, resulting in jumping of the key.

3. Circuit problem: The circuit problem of the health pot may also cause the key to jump. Problems such as circuit failure, electronic component damage or poor contact may lead to abnormal key operation.

4. Software problems: If the health pot uses an electronic control system, software problems may lead to button tripping. For example, a program error or firmware problem may lead to incorrect key signal interpretation.
