Description

Technical Field

[0001] The present invention relates to the technical field of umbrellas, and particularly to a self-driven environmentally friendly luminous oil-paper umbrella. Background Art

[0002] The oil-paper umbrella is a traditional handicraft, often used in photography and artistic creation, with profound cultural heritage. The umbrella surface of the traditional oil-paper umbrella is usually made of rice paper and coated with tung oil to enhance water resistance. The umbrella ribs and umbrella handle are made of bamboo and wood. Its production process is exquisite and the appearance is beautiful. It is not only a practical tool in daily life, but also often used in various wedding and festival occasions. However, due to its material characteristics, the traditional oil-paper umbrella has certain limitations in modern society. For example, the waterproof effect gradually weakens over time, the durability of the umbrella surface is insufficient, it is prone to mildew or cracking in a humid environment, the smell of tung oil is strong, and it is flammable. In addition, the traditional umbrella handle has a single function and is difficult to meet the diverse living needs of modern people.

[0003] At present, the limitations of the traditional oil-paper umbrella can no longer meet people's higher requirements for environmental protection, durability, and versatility. For example, tung oil as a coating material not only has the problem of decreasing waterproof performance, but also has odors and flammability during its use; the strength of the traditional rice paper of the umbrella surface is low and it is easy to tear after long-term use; the umbrella handle, as a support structure, has a relatively single function and cannot provide additional practicality.

[0004] Therefore, there is an urgent need for a self-driven environmentally friendly luminous oil-paper umbrella. By adopting modern advanced technologies, the oil-paper umbrella can have stronger waterproofness, durability, and versatility, while retaining the aesthetic value of traditional craftsmanship and meeting the needs of modern users.

A plurality of support frames for retracting or expanding the umbrella surface are arranged on the circumferential direction of the bamboo slider. One end of the support frame away from the bamboo slider is connected to the edge of the umbrella surface. A first LED lamp is installed at the edge of the support frame close to the umbrella surface. A second LED lamp is installed at the center of the end of the umbrella surface facing away from the support frame. The first LED lamp and the second LED lamp are connected to the power supply system; the power supply system includes a rotary self-driven power generation device installed at the end of the umbrella rod.

[0007] Preferably, a hidden switch control and a capacitor for controlling and powering the first LED lamp and the second LED lamp are provided inside the knob-type self-driven power generation device.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Referring to Figures 1 - 5 , the present invention provides a self-driven environmentally friendly luminous oil paper umbrella, including an umbrella rod 5. One end of the umbrella rod 5 is installed with a power supply system, and the other end of the umbrella rod 5 is installed with an umbrella surface 11. The umbrella rod 5 is sleeved with a bamboo jumper 6 that slides along the umbrella rod 5. A plurality of support frames for retracting or expanding the umbrella surface 11 are arranged on the circumference of the bamboo jumper 6. One end of the support frame away from the bamboo jumper 6 is connected to the edge of the umbrella surface 11. A first LED lamp 10 is installed near the edge of the umbrella surface 11 of the support frame. The center of the end of the umbrella surface 11 facing away from the support frame is installed with a second LED lamp 13. The first LED lamp 10 and the second LED lamp 13 are connected to the power supply system; the power supply system includes a knob type self-driven power generation device 4 installed at the end of the umbrella rod 5.

[0028] The diameter of the umbrella surface 11 is 84 cm. The coating of the umbrella surface 11 is a nano-porous titanium dioxide coating. An aesthetic pattern can be coated on this nano-porous titanium dioxide coating. This nano-porous titanium dioxide pattern emits light by absorbing the light of the first LED lamp 10 and the second LED lamp 13, which can achieve the effect of beautifying the oil-paper umbrella. And this nano-porous titanium dioxide coating can also play the role of antibacterial, mildew-proof and anti-corrosion, increasing the service life of the oil-paper umbrella.

[0029] The present invention combines modern technology with traditional oil-paper umbrellas, retains the classic beauty of the oil-paper umbrellas and endows them with various practical functions; the rotary self-driven power generation device 4 supplies power to the first LED lamp 10 and the second LED lamp 13, enabling the oil-paper umbrella to effectively provide lighting and warning functions when used at night or in a dim environment; the environmentally friendly and energy-saving design that can generate electricity independently through the rotary self-driven power generation device 4 also conforms to the modern lifestyle and environmental protection concept.

[0030] In a further optimized solution, a hidden switch control 2 and a capacitor 3 for controlling and supplying power to the first LED lamp 10 and the second LED lamp 13 are arranged in the rotary self-driven power generation device 4.

[0031] The capacitor 3 supplies power to the first LED lamp 10 and the second LED lamp 13.

[0032] The hidden switch control 2 controls the first LED lamp 10 and the second LED lamp 13 to turn on and off.

[0033] In a further optimized solution, a handle cover 1 is installed at one end of the rotary self-driven power generation device 4 away from the umbrella rod 5, and the hidden switch control 2 is installed between the handle cover 1 and the rotary self-driven power generation device 4. By installing the hidden switch control 2 between the handle cover 1 and the rotary self-driven power generation device 4, it is convenient for the user to control the first LED lamp 10 and the second LED lamp 13 to turn on and off through the hidden switch control 2.

[0034] In a further optimized solution, the support frame includes a short umbrella rib 7 hinged to the bamboo jump 6. The end of the short umbrella rib 7 away from the bamboo jump 6 is hinged to the middle of a long umbrella rib 8. One end of the long umbrella rib 8 is connected to the edge of the umbrella surface 11 through a tail bead, and the other end of the long umbrella rib 8 is hinged to an upper nest 9. The short umbrella rib 7 and the long umbrella rib 8 can effectively fold and unfold the umbrella surface 11.

[0035] The wires between the first LED lamp 10 and the second LED lamp 13 and the hidden switch control 2 and the capacitor 3 are hidden inside the umbrella rod 5, the short umbrella rib 7 and the long umbrella rib 8.

[0036] The first LED lamp 10 is installed between the long umbrella rib 8 and the tail bead. Through the first LED lamp 10, the edge of the umbrella surface 11 can be effectively illuminated. It can not only illuminate the umbrella surface 11, but also effectively illuminate the edge of the umbrella surface 11, serving as a warning for the outline size of the umbrella surface 11.

[0037] In a further optimized solution, the upper nest 9 is sleeved on the umbrella rod 5 and fixedly connected to the umbrella rod 5, enabling the short umbrella ribs 7 and the long umbrella ribs 8 to effectively fold and unfold the umbrella surface 11.

[0038] In a further optimized solution, one end of the umbrella rod 5 away from the knob-type self-driven power generation device 4 penetrates through the center of the umbrella surface 11 and is connected to the second LED lamp 13. An umbrella cap 12 is installed at the end of the umbrella rod 5 extending out of the umbrella surface 11. A number of second LED lamps 13 are installed. By installing a number of second LED lamps 13 between the umbrella surface 11 and the umbrella cap 12, not only can the second LED lamps 13 illuminate the umbrella surface 11 to beautify the umbrella surface 11, but also the overall outline of the umbrella surface 11 can be illuminated by the second LED lamps 13 and the first LED lamp 10.

[0039] In a further optimized solution, the umbrella surface 11 is made of sisal fiber paper. Hydrophobic sisal paper is used as the material of the umbrella surface 11.

[0040] In a further optimized solution, the knob-type self-driven power generation device 4 adopts a sisal cellulose-based triboelectric nanogenerator. The negative electrode material of the sisal cellulose-based triboelectric nanogenerator is PTEF, and the positive electrode material is sisal fiber paper; its diameter is 4 cm and its length is 15 cm.

[0041] Structure and working principle of the sisal cellulose-based triboelectric nanogenerator (TENG):

[0042] The sisal cellulose-based TENG usually adopts the classic vertical contact-separation mode structure, mainly including the following four layers:

[0043] Friction layer A (sisal cellulose layer): Sisal cellulose is chemically treated (such as alkali treatment, nanofibrillation) to form a thin film or fiber network with a high specific surface area, having high crystallinity, strong mechanical properties and natural hydrophilicity; as a positive-polarity friction material, it is easy to lose electrons and becomes positively charged after contact.

[0044] Friction layer B (high electron affinity material layer): Polytetrafluoroethylene (PTFE), polyimide (PI), etc., having strong negative electricity; as a negative-polarity friction material, it captures electrons and becomes negatively charged after contact.

[0045] Electrode layer: Conductive materials (such as aluminum foil, copper foil, ITO conductive glass or flexible conductive fabric); respectively attached to the back of the two friction layers for collecting charges and conducting current.

[0046] Spacer layer: Maintain an adjustable separation distance between the two friction layers through springs or elastic brackets to achieve periodic contact-separation motion.

[0047] Based on the coupling effect of contact electrification and electrostatic induction, the working cycle is divided into four stages:

[0048] Initial contact: The two friction layers are closely contacted under an external force. Due to the difference in electron affinity, electrons transfer from sisal cellulose (low electron affinity) to PTFE (high electron affinity), resulting in the sisal being positively charged and the PTFE being negatively charged.

[0049] Separation stage: After the external force is removed, the friction layers quickly separate, and the surface charges cannot be neutralized, forming a potential difference; the electrostatic induction effect causes opposite charges to be induced on the two electrodes: a positive charge is induced on the PTFE side electrode, and a negative charge is induced on the sisal side electrode; the potential difference drives electrons to flow from the sisal side electrode through the external circuit to the PTFE side electrode, generating an instantaneous current (forward current).

[0050] Maximum separation state: When the separation distance is the largest, the electrostatic force of the system is balanced, and the current temporarily stops.

[0051] Re-contact: Under the action of an external force, the friction layers re-contact, the surface charges are partially neutralized, the induced charges on the electrodes decrease, and electrons flow in the reverse direction (reverse current), completing one cycle.

[0052] Advantages of sisal cellulose:

[0053] Sustainability: Derived from renewable plants, biodegradable, reducing environmental pollution.

[0054] High performance: High mechanical strength (tensile strength ≈ 500 MPa) and surface roughness, enhancing the triboelectric charge density.

[0055] Cost-effectiveness: Inexpensive raw materials, simple processing (such as solution casting, electrospinning).

[0056] Functionalization potential: The output performance can be further improved by doping nanoparticles (such as TiO2) or chemical modification.

[0057] The sisal cellulose-based TENG efficiently converts mechanical energy into electrical energy through structural design and material optimization, combining environmental protection and high performance.

[0058] Further optimization scheme: The short rib 7 is adapted to the long rib 8. Both the short rib 7 and the long rib 8 are made of bamboo. A number of short ribs 7 are arranged around the bamboo jump 6 in a circular pattern.

[0059] Further optimization scheme: The length of the umbrella rod 5 is greater than the length after the short rib 7 and the long rib 8 are folded. The length of the umbrella rod 5 is 60 - 70 cm, and the umbrella rod 5 is made of bamboo and is hollow in the middle.

[0060] The umbrella rod 5, bamboo jump 6, short umbrella ribs 7, long umbrella ribs 8, upper nest 9, umbrella surface 11 and umbrella cap 12 are all coated with a nano-porous titanium dioxide coating. The nano-porous titanium dioxide coating layer can effectively achieve the effects of antibacterial, mildew-proof and anti-corrosion, and increase the service life of the oil-paper umbrella.

[0061] Working process: When in use, when pressing the hidden switch control 2 provided on the handle cover 1, the capacitor 3 supplies power to the first LED lamp 10 and the second LED lamp 13 through the hidden switch control 2, so that both the first LED lamp 10 and the second LED lamp 13 are lit and emit light. Controlled by the hidden switch control 2, when the capacitor 3 runs out of power, the rotary knob type self-driven power generation device 4 can be rotated to generate electricity, continuously supply power to the first LED lamp 10 and the second LED lamp 13 and at the same time charge the capacitor 3. The lighting modes can be divided into constant on, slow flash, fast flash and various color switching modes such as red, yellow, green, blue, indigo, violet, etc.

[0062] In the present invention, the first LED lamp 10 is arranged on the long umbrella rib 8 and the tail bead, the second LED lamp 13 is arranged between the umbrella cap 12 and the umbrella surface 11, and the capacitor 3 is used to supply power to the first LED lamp 10 and the second LED lamp 13 in cooperation with the hidden switch control 2. The coating of the umbrella surface 11 is a nano-porous titanium dioxide coating, and beautiful patterns can be drawn on the nano-porous titanium dioxide coating, and it emits light by absorbing the light of the first LED lamp 10 and the second LED lamp 13; when the capacitor 3 runs out of power, the rotary knob type self-driven power generation device 4 can be rotated to generate electricity, supply power to the first LED lamp 10 and the second LED lamp 13 and at the same time charge the capacitor 3, adding the practicality and ornamental value of the oil-paper umbrella while realizing the night lighting function.
