The invention discloses an expansion capsule providing power. The expansion capsule comprises a heating element and an expansion medium. The expansion medium is evenly wrapped on the surface of the heating element to form an expansion assembly jointly, and the expansion capsule further comprises an elastic part. When the heating element performs heating, the expansion medium expands towards the periphery and acts on the elastic part to enable the elastic part to perform elastic deformation. When the heating element stops heating, the elastic part tightly adheres to the expansion medium under the effect of resilience force and enables the expansion medium to contract to an initial state.
