Technical Field
[0001] This invention relates to the field of bathroom products and bamboo product processing technology, and in particular to a flattened bamboo round multifunctional bathroom lamp. Background Technology
[0002] With the global popularization of green and environmentally friendly concepts and the rapid development of the smart home industry, the bathroom, as an important area of home life, has seen its products' environmental friendliness, multifunctionality, and environmental adaptability become a focus for consumers. Bathroom lights, as essential equipment in the bathroom, not only need to provide illumination but also require moisture resistance, durability, aesthetic appeal, and efficient space utilization. Traditional bathroom light products have gradually revealed numerous technical deficiencies in material selection, structural design, and manufacturing processes, making it difficult to meet the comprehensive requirements of modern homes for environmental friendliness, multifunctionality, and high precision.
[0003] Bamboo, with its short growth cycle, high fiber density, natural and beautiful texture, and environmentally friendly and biodegradable properties, has become an ideal alternative to traditional non-environmentally friendly materials and has seen initial applications in the manufacture of mirror frames. However, existing bamboo frame applications are mostly concentrated in cosmetic mirrors and ordinary hanging mirrors, and are primarily rectangular or elliptical non-circular structures, making it difficult to adapt to the assembly requirements of bathroom lights that require circular frames. For example, Chinese utility model patent CN211657583U discloses "A Bamboo Mirror Frame with Stainless Steel Base for a Three-Dimensional Cosmetic Mirror," whose bamboo frame adopts a rectangular structure and is directly processed from cylindrical raw bamboo material. Although LED light strings are added for supplementary lighting, it does not involve the molding technology of circular bamboo frames, and its function is limited to the basic use scenario of a cosmetic mirror, lacking the moisture-proof design and storage function required for bathroom spaces. Chinese utility model patent CN215838187U discloses "A Bamboo Frame Mirror," whose frame is elliptical, relying on the natural curvature of the bamboo or simple bending. The curved shape solves the problem of lens wobbling by using positioning rubber rings, but it does not use mold and pressure control technology, resulting in low molding accuracy. It only has a single function of grooming and has no integrated design of lighting and storage. The Chinese utility model patent with authorization announcement number CN219331227U discloses "a bamboo and wood ring wall-mounted mirror". Although it adopts a circular bamboo and wood frame structure, the frame is spliced from bamboo and wood rings rather than being integrally molded, resulting in poor surface aesthetics. Its functional design focuses on providing reminders through magnetic stickers. Although light strips are added, there are no reasonable storage partitions, which cannot meet the convenient needs of classifying and storing small items in the bathroom. Summary of the Invention
[0004] The problem to be solved by the present invention is to provide a flattened bamboo round multifunctional bathroom lamp that is environmentally friendly, moisture-proof, multifunctional and highly adaptable.
[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: This flattened bamboo round multifunctional bathroom lamp includes a round bamboo frame. The round bamboo frame is made by flattening bamboo material and then undergoing a two-stage high-temperature softening and molding process. The two-stage high-temperature softening and molding process includes a first high-temperature softening and a second high-temperature softening.

S9: The circular frame obtained in step S7 is subjected to drying and anti-corrosion treatment. The drying treatment is low-temperature drying, and the moisture content of the flattened bamboo is controlled at 8-12% after drying. The anti-corrosion treatment is soaking in a natural plant extract preservative for 10-15 minutes. The plant extract preservative is made by mixing bamboo vinegar and tea polyphenols in a mass ratio of 3:1. After the treatment, a circular bamboo frame is obtained. Corresponding slots are symmetrically arranged on the inner surface of the side wall of the lower part of the circular bamboo frame. The slot is located at the center of the inner surface of the lower side wall of the circular bamboo frame.
[0007] In some possible implementations, the bamboo back panel is manufactured as follows: the flattened bamboo obtained in step S3 of the circular bamboo frame is first cooled and dried, and the moisture content is controlled at 12%-15%. Then, the cooled and dried flattened bamboo is selected, and environmentally friendly bamboo glue is evenly coated on its side. The amount of glue is 150g / m²-200g / m². After gluing and splicing, it is processed into a circular structure that fits the circular bamboo frame by a rounding machine. Then, it is dried and treated with anti-corrosion treatment in sequence. The thickness of the bamboo back panel is 0.3cm-0.5cm. The bamboo back panel is fixed to the back of the circular bamboo frame by secondary gluing with environmentally friendly bamboo glue, and its back is sealed.
[0008] In some possible implementations, the bamboo divider is manufactured as follows: the flattened bamboo obtained from step S3 of the circular bamboo frame is first cooled and dried, and the moisture content is controlled at 12%-15% after drying. Then, the cooled and dried flattened bamboo is selected, cut and processed according to a preset size, and then dried and treated with anti-corrosion treatment in sequence. The bamboo divider is 0.3cm-0.5cm thick, and its upper edge is provided with anti-slip chamfer. It is detachably connected to the inner wall of the circular bamboo frame through the slot, dividing the inner side of the frame into multiple independent storage compartments.
[0009] In some possible implementations, the slider is provided with a dovetail groove, the slider is installed in the middle of the circular bamboo frame, the guide rail passes through the dovetail groove, and the light-transmitting area on the back of the mirror body is annular, which is located on the mirror body near the bamboo fixed frame.
[0010] In some possible implementations, the environmentally friendly bamboo adhesive in step S5 is a formaldehyde-free bamboo-specific adhesive, whose main components are bamboo fiber powder, modified starch, and water in a mass ratio of 2:5:3, and the solid content of the adhesive is 40-50%.
[0011] In some possible implementations, the inner side of the arc-shaped extrusion die is provided with a high-temperature resistant anti-slip pad layer, the anti-slip pad layer is made of silicone material and has a thickness of 0.2 mm - 0.3 mm; the height of the cylindrical forming mandrel is consistent with the thickness of the circular bamboo frame; the height of the arc-shaped extrusion die is adapted to the height of the cylindrical forming mandrel.
[0012] In some possible implementations, a positioning rubber ring is provided on the inner side of the bamboo fixing frame of the mirror assembly, and the mirror body is interference-fitted with the bamboo fixing frame through the positioning rubber ring. The positioning rubber ring is made of EPDM waterproof rubber material.
[0013] In some possible implementations, the LED light strip is a waterproof flexible light strip with a power of 5-10W, and the button is a waterproof push-button with an integrated control chip and a luminous coating on its surface.
[0014] In some possible implementations, the outer surface of the circular bamboo frame is sequentially provided with an anti-corrosion and brightening coating and a waterproof coating. The anti-corrosion and brightening coating is a transparent polyurethane varnish with a thickness of 0.05 mm to 0.1 mm; the waterproof coating is a nano-silane waterproofing agent with a thickness of 0.02 mm to 0.03 mm.
[0015] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. The circular bamboo frame, bamboo back panel, and bamboo divider of this invention are all made of natural bamboo. Bamboo is renewable, biodegradable, environmentally friendly, and pollution-free. The circular bamboo frame is made by flattening bamboo and then undergoing two high-temperature softening molding processes. The two high-temperature softening processes further enhance the flexibility and plasticity of the flattened bamboo, eliminate the internal stress generated during the flattening process, and ensure that it is not easy to crack during subsequent extrusion molding. Moreover, the shape is stable after molding and is not easy to spring back.
[0016] 2. This invention uses a cylindrical bamboo frame formed by extrusion molding through a cylindrical forming mandrel and multiple sets of arc-shaped extrusion die segments. Combined with hydraulic extrusion and real-time monitoring by pressure sensors, it solves the problems of difficulty and low precision in forming flat bamboo into a circle. During the molding process, by controlling the high-temperature softening parameters, extrusion pressure and curing conditions, it can ensure high dimensional accuracy and good consistency of the circular bamboo frame, with a molding rate of over 95%. The entire molding process is highly automated and suitable for mass production.
[0017] 3. This invention integrates three major functions: lighting, grooming, and categorized storage. The LED light strip provides soft and adjustable lighting to meet the needs of different bathroom scenarios; the mirror body facilitates grooming; the bamboo divider divides the mirror frame into multiple independent storage compartments, allowing for the categorized storage of small bathroom items, reducing the space occupied by the washbasin, and improving the tidiness of the bathroom space. The divider is also detachable to adapt to different storage needs. The control buttons are installed on the mirror body, making operation convenient and waterproof, suitable for the humid bathroom environment, solving the problems of cumbersome control methods and susceptibility to moisture in traditional bathroom lights.
[0018] 4. The mirror body is slidably attached to the surface of the round bamboo frame, covering and sealing the inside of the round bamboo frame to prevent moisture from entering its internal storage space. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0032] like Figures 1-4This embodiment 1, as shown, proposes a flattened bamboo circular multifunctional bathroom lamp, including a circular bamboo mirror frame 1. A bamboo back panel 2 is attached to the back of the circular bamboo mirror frame, sealing the back of the circular bamboo mirror frame 1. Multiple slots 3 for engaging bamboo dividers 4 are provided on the inner side of the circular bamboo mirror frame 1. The bamboo dividers 4 are inserted into the slots 3 to divide the mirror frame into multiple independent storage compartments. A slider 5 with a dovetail groove is installed in the middle of the bamboo back panel inside the circular bamboo mirror frame 1. A mirror assembly is installed on the front of the circular bamboo mirror frame 1. This mirror assembly has a circular mirror body 6 and an LED light strip 7. The circular mirror body 6 is slidably connected to the slider 5 in the middle of the circular bamboo mirror frame 1 via a guide rail 8 located on its back. The guide rail 8 passes through the dovetail groove 5-1, and limit blocks are provided at both ends of the guide rail to prevent the mirror assembly from sliding excessively and detaching from the slider. When the mirror body is returned to its original position, the inside of the circular bamboo frame 1 can be covered to prevent moisture from entering the internal storage space. By pushing the mirror assembly to the left or right, the mirror assembly can slide to the left or right, revealing the storage space inside the circular bamboo frame, where small bathroom items such as soap, small bottles of shower gel, and shampoo can be placed or retrieved. When the mirror assembly slides, the sliding gap between the circular bamboo frame and the mirror assembly is controlled at 0.1-0.2mm. A bamboo fixing frame 9 is installed around the perimeter of the mirror body 6. The lower part of the mirror body has mounting holes for installing control buttons 10 for controlling the LED light strip 7. The LED light strip 7 is pasted on the light-transmitting section on the back of the mirror body 6, with the light-emitting surface of the light strip facing the front of the mirror. The light-transmitting section is annular and is located on the mirror body 6 near the bamboo fixing frame 9. The LED light strip 7 is a waterproof flexible light strip.
[0033] In embodiment 1, a positioning rubber ring 13 may also be provided on the inner side of the bamboo fixing frame 9 of the mirror assembly. The mirror body 6 is interference-fitted with the bamboo fixing frame 9 through the positioning rubber ring 13. The positioning rubber ring 13 is made of EPDM waterproof rubber material.
[0034] In Example 1, the power of the waterproof flexible light strip can be 5W-10W, the color temperature can be adjusted between 3000K (warm light) and 6000K (cool light), and the brightness adjustment range can be 10-100% to meet the needs of different lighting scenarios; the control button 10 can be a waterproof push-button, which integrates a control chip and has a luminous coating on its surface. The LED light strip can be started, stopped, and its brightness adjusted by operating the control button.
[0035] In Example 1, the outer surface of the circular bamboo frame may be provided with an anti-corrosion and brightening coating 14 and a waterproof coating 15 in sequence. The anti-corrosion and brightening coating 14 is a transparent polyurethane varnish with a thickness of 0.05 mm-0.1 mm; the waterproof coating 15 is a nano silane waterproofing agent with a thickness of 0.02 mm-0.03 mm.
[0036] In Example 1, the fabrication of the circular bamboo frame 1 includes the following steps: S1: Select 3-5 year old moso bamboo with a diameter of 8-12cm, cut bamboo segments of appropriate length using a bamboo cutting machine, ensuring that both ends of the bamboo segments are flat and without tilting; then send the bamboo segments into a bamboo splitting machine to evenly split them into several parts along the bamboo segment axis to obtain arc-shaped bamboo blanks. S2: Place the arc-shaped bamboo blank obtained in step S1 into a steam heating furnace for the first high-temperature softening. Saturated steam is introduced and softened for 4 to 10 minutes at a temperature of 160℃-180℃ and a steam pressure of 0.15MPa-0.2MPa. S3: Place the arc-shaped bamboo blank obtained in step S2 into the flattening device within 2 minutes, remove the nodes, green parts, and yellow parts, and then gradually flatten it to obtain flattened bamboo with a thickness of 0.3cm-0.5cm and a width of 8-10cm; S4: Place the flattened bamboo obtained in step S3 into a steam heating furnace for a second high-temperature softening process. Introduce saturated steam and soften for 4-8 minutes at a temperature of 170℃-180℃ and a steam pressure of 0.18-0.2MPa. S5: After softening, quickly remove the flattened bamboo within 2 minutes and transfer it to the glue application station to avoid the bamboo strips cooling down and reducing their toughness, which would affect the glue application and subsequent shaping. Use a brush to evenly apply environmentally friendly bamboo glue to the green surface of the flattened bamboo and the two ends. During the glue application process, maintain a 45° angle between the brush and the bamboo strip and apply the glue at a uniform speed to avoid missed areas or glue buildup. The amount of glue applied is 150 g / m²-200 g / m². S6: Prepare the forming mold. The forming mold includes a cylindrical forming mandrel 11 and four sets of arc-shaped extrusion mold pieces 12. After the four sets of arc-shaped extrusion mold pieces 12 are joined together, they form a circular cavity that matches the outer diameter of the circular bamboo frame 1. A pressure sensor is provided inside the mold. The pressure sensor is electrically connected to the hydraulic control system. S7: Place multiple flattened bamboo strips obtained in step S5 on the outer circumference of the cylindrical forming mandrel 11 in a staggered, multi-layered manner, with the joints of adjacent bamboo strips staggered. Then, start the hydraulic device, set the extrusion speed to 1-2 mm / s, and drive the four sets of arc-shaped extrusion die petals 12 to move synchronously towards the central cylindrical forming mandrel. During the movement of the die, observe the bamboo strip adhesion in real time to avoid deviation or wrinkling. When the die contacts the bamboo strip, the hydraulic system automatically switches to pressure control mode. The pressure sensor monitors the extrusion pressure in real time and controls the pressure value within the range of 5 MPa-10 MPa, maintaining this extrusion state for 20-40 minutes. S8: After step S7, turn off the hydraulic device and remove all the arc-shaped extrusion molds. Remove the formed flattened bamboo circular frame from the cylindrical forming mandrel. S9: The circular frame obtained in step S7 is dried and preserved. The drying process is low-temperature drying, and the moisture content of the flattened bamboo is controlled at 8-12% after drying. The preservation process involves soaking the bamboo in a natural plant extract preservative for 10-15 minutes. The plant extract preservative is made by mixing bamboo vinegar and tea polyphenols in a mass ratio of 3:1. After the treatment, a circular bamboo frame is obtained.
[0037] The production steps of the bamboo back panel are as follows: The flattened bamboo obtained from step S3 of the circular bamboo frame is first cooled and dried, with the moisture content controlled at 12%-15%. Then, the cooled and dried flattened bamboo is evenly coated with environmentally friendly bamboo glue. This environmentally friendly bamboo glue is a formaldehyde-free bamboo-specific adhesive, its main components being bamboo fiber powder, modified starch, and water in a mass ratio of 2:5:3. The solid content of the adhesive is 40-50%, and the amount of environmentally friendly bamboo glue applied to the sides of the flattened bamboo is 150g / m²-200g / m². After gluing and splicing, it is processed into a circular structure suitable for the circular bamboo frame using a rounding machine. Subsequently, it undergoes drying and anti-corrosion treatment. The drying method uses low-temperature drying, with the moisture content controlled at 8%-12% after drying. The anti-corrosion treatment uses a natural plant extract preservative, which is composed of bamboo vinegar and tea polyphenols in a mass ratio of 3:1. The mixture is made by soaking the circular structure in a preservative for 10-15 minutes. After processing, a bamboo back panel is obtained with a thickness of 0.3cm-0.5cm. The bamboo back panel is then fixed to the back of the circular bamboo frame with environmentally friendly bamboo glue to seal the back.
[0038] The production steps of the bamboo divider are as follows: The flattened bamboo obtained from step S3 of the round bamboo frame is first cooled and dried. After drying, the moisture content is controlled at 12%-15%. Then, the cooled and dried flattened bamboo is selected, cut and processed according to the preset size, and then subjected to drying and anti-corrosion treatment in sequence. The drying method is low-temperature drying, and the moisture content is controlled at 8-12% after drying. The anti-corrosion treatment uses a natural plant extract preservative, which is made by mixing bamboo vinegar and tea polyphenols in a mass ratio of 3:1. The flattened bamboo pieces are soaked in the preservative for 10-15 minutes. After the treatment, the bamboo divider is obtained. The thickness of the bamboo divider is 0.3cm-0.5cm. Its upper edge is provided with anti-slip chamfer. It is detachably connected to the round bamboo frame through a slot, dividing the inside of the frame into multiple independent storage compartments.
