Elongated illuminant storage device
View Patent ↗The present application discloses an elongated illuminant storage device, including: a reel rotatable about an axis thereof; a spiral spring energy storage member connected to the reel and configured to store a potential energy generated during rotation of the reel; an elongated illuminant made of a flexible material, wound on the reel, and having one end fixedly connected to the reel and the other end being a free end, where when an outward pulling force is applied to the free end, the elongated illuminant is capable of being pulled out, and the reel is driven to rotate, in this case, the spiral spring energy storage member stores the potential energy generated during rotation of the reel, and when the pulling force is removed, the spiral spring energy storage member causes the reel to rotate reversely by means of the stored potential energy.
1 . An elongated illuminant storage device, comprising:
a reel rotatable about an axis thereof;
a spiral spring energy storage member connected to the reel;
an elongated illuminant having one end fixedly connected to the reel and the other end being a free end, wherein a portion of the elongated illuminant between the one end and the free end is capable of being wound around the reel, when a pulling force is applied to the free end, the elongated illuminant is capable of being pulled out, and the reel is driven to rotate forwardly, causing the spiral spring energy storage member to store a potential energy generated by rotation of the reel, and when the pulling force is removed, the spiral spring energy storage member releases the stored potential energy to cause the reel to rotate reversely; and
a housing for accommodating the storage device, an electrical energy storage element and the elongated illuminant;
wherein the reel is provided with a spiral guide groove for guiding the elongated illuminant to be wound and stored layer by layer in an axial direction of the reel, the spiral guide groove having a groove width adapted to a width or diameter of the elongated illuminant.
2 . The elongated illuminant storage device according to claim 1 , wherein an end cap is provided at the free end, and a through hole is provided in the end cap for passage of an external fixing member to connect the free end of the elongated illuminant to the external fixing member.
3 . The elongated illuminant storage device according to claim 1 , wherein the elongated illuminant is a flexible light strip or light string.
4 . The elongated illuminant storage device according to claim 1 , wherein the housing is provided with an opening for the elongated illuminant to pass through.
5 . The elongated illuminant storage device according to claim 1 , further comprising the electrical energy storage element, the electrical energy storage element being electrically connected to the elongated illuminant for providing electrical energy to the elongated illuminant.
