[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0024] refer to Figures 1 to 3 In this embodiment, the elongated light-emitting body storage device 100 includes: a reel 1, which is rotatable relative to its own axis; a coiled spring energy storage element 2, which is connected to the reel 1; an elongated light-emitting body 3, one end of which is fixedly connected to the reel 1, and the other end is a free end 31. The portion between the one end and the other end can be wound around the reel 1. A pulling force applied to the free end 31 can pull out the elongated light-emitting body 3 and drive the reel 1 to rotate in the forward direction, so that the coiled spring energy storage element 2 stores the potential energy of the rotation of the reel 1; when the pulling force is released, the coiled spring energy storage element 2 releases the stored potential energy, causing the reel 1 to rotate in the reverse direction; and a housing 4 for accommodating the storage device, the energy storage element 6, and the elongated light-emitting body 3.

[0025] According to the elongated light-emitting body storage device 100 of this embodiment, in its natural state, the elongated light-emitting body 3 is stored in the reel 1. At this time, the elastic potential energy of the coil spring energy storage member 2 is at its minimum, and its tightening force prevents the elongated light-emitting body 3 from naturally extending out of the reel 1. When the free end 31 is pulled, the rotation of the reel 1 increases the elastic potential energy of the coil spring energy storage member 2. Therefore, when the pulling force on the elongated light-emitting body 3 is released, this elastic potential energy is converted into a force that causes the reel 1 to rotate in the opposite direction, thereby causing the elongated light-emitting body 3 to retract into the reel 1. In some embodiments, the coil spring energy storage member 2 also has a limiting function, that is, when the pulling force is released when the elongated light-emitting body 3 is pulled out to a certain length, the coil spring energy storage member 2 can limit the reverse rotation of the reel 1. When the limiting function of the coil spring energy storage member 2 is actively released, the elastic potential energy in the coil spring energy storage member 2 can be converted into a force that causes the reel 1 to rotate in the opposite direction. The elongated light-emitting element storage device 100 according to this embodiment facilitates the use of the elongated light-emitting element 3. The elongated light-emitting element 3 can be directly pulled out from the reel 1 for use, and it is less prone to tangling. During storage, due to the action of the coil spring energy storage element 2, the elongated light-emitting element 3 can be automatically retracted into the reel 1, making operation convenient and easy to carry. By providing the outer shell 4, the reel 1, the coil spring energy storage element 2, and the elongated light-emitting element 3 housed within can be protected from damage by external objects, while also facilitating storage and carrying. In some embodiments, the outer shell 4 includes a housing 41 and a base 42. In some embodiments, only the base 42 may be provided without the housing 41.

[0026] refer to Figures 1 to 3 In some embodiments, the reel 1 is provided with a spirally wound guide groove 11 for guiding the elongated light-emitting element 3 to be wound and stored layer by layer along the axial direction of the reel 1. The width of the guide groove 11 is adapted to the width or diameter of the elongated light-emitting element 3. In this embodiment, the guide groove 11 makes the storage and pulling-out process of the elongated light-emitting element 3 smoother and restricts the displacement of the elongated light-emitting element 3. After storage, the elongated light-emitting element 3 is evenly arranged along the radial direction of the reel 1, which can further save space and make it easy to carry. It is understood that in some embodiments, the storage method of the elongated light-emitting element 3 can be horizontal reel 1 storage or vertical spiral storage.

[0027] refer to Figures 1 to 3 In some embodiments, the free end 31 is provided with an end cap 32, on which a through hole 321 for suspending the elongated light-emitting body 3 is provided. The end cap 32 makes it easier to exert force when pulling out the elongated light-emitting body 3, and the through hole 321 makes it convenient to suspend or fix the elongated light-emitting body 3 in any position, which is suitable for a variety of usage scenarios.

[0028] In some embodiments, the elongated light-emitting element 3 is a flexible light strip or light string. In this embodiment, the light strip is typically a continuously emitting strip with equal radii in each segment, and the light string is typically composed of multiple independent light bulbs connected in series by wires. Further, the elongated light-emitting element 3 can be a flexible printed circuit board (FPCB) light strip, a sleeved flexible light strip, a copper wire light string, a sleeved copper wire light string, etc. Due to its flexibility, it can be rolled up and stored, and can be arranged as needed, suitable for outdoor or multi-scene deployment. It is understood that the elongated light-emitting element 3 can be any form of strip-shaped flexible light-emitting element.

[0029] refer to Figures 1 to 3 In some embodiments, the outer casing 4 is provided with an opening 411 for the elongated light-emitting element 3 to pass through. The longitudinal length of the opening 411 is set according to the axial distance of the guide groove 11 along the reel 1, so that the elongated light-emitting element 3 can pass through the opening 411 when pulled out or retracted to any length without opening the outer casing 4.

[0030] refer to Figures 2 to 3 In some embodiments, an energy storage element 6 is also provided, which is electrically connected to the elongated light-emitting body 3 and is used to provide electrical energy to the elongated light-emitting body 3. The elongated light-emitting body storage device 100 according to this embodiment can achieve self-powered operation without relying on a fixed power source, and the elongated light-emitting body 3 can be deployed at any time in any scenario, especially outdoors where there is no power source.

[0031] In some embodiments, the energy storage element 6 is a ternary lithium battery or a lithium cobalt oxide battery. Since ternary lithium batteries or lithium cobalt oxide batteries have high energy density, they are suitable for use as energy storage elements 6 in small-volume electrical appliances.

[0032] refer to Figures 2 to 3 In some embodiments, a battery bracket 7 is provided, which is connected to the reel 1 to fix the energy storage element 6 to the reel 1. In this embodiment, the battery can rotate together with the reel 1, so that the battery and the end of the elongated light-emitting body 3 fixed to the reel 1 remain relatively stationary, preventing the wires of the battery and the elongated light-emitting body 3 from breaking due to excessive rotation during the rotation process.

[0033] refer to Figure 3 In some embodiments, a printed circuit board 8 and a charging contact 9 are also provided. The printed circuit board 8 is electrically connected to the energy storage element 6, and the charging contact 9 is electrically connected to the printed circuit board 8 for charging the energy storage element 6. The charging contact 9 allows the energy storage element 6 to be charged. The circuit board can control the charging power and actively stop charging when the battery is fully charged to prevent overcharging from affecting the battery's lifespan.

[0034] refer to Figures 2 to 3 In some embodiments, a circuit board support 10 is also provided to fix the printed circuit board 8 to the reel 1, and the charging contact 9 is disposed on the circuit board support 10. In this embodiment, the printed circuit board 8, the charging contact 9, and the battery can rotate together with the reel 1, so as to keep them relatively stationary relative to the end of the elongated light-emitting body 3 that is fixed to the reel 1, and to prevent the wires connecting the various electrical components from breaking due to excessive rotation during the rotation process.

[0035] According to the present invention, the long light-emitting body storage device 100 facilitates the use of the long light-emitting body 3. The long light-emitting body 3 can be directly pulled out from the reel 1 for use, and it is not easy to get tangled or knotted. When storing, due to the function of the coil spring energy storage component 2, the long light-emitting body 3 can be automatically retracted into the reel 1, which is convenient to operate and easy to carry. The built-in energy storage component 6 can directly provide power to the long light-emitting body 3 without the need for an external power source, making it more suitable for use in multiple scenarios.
