Description

Technical Field

[0001] This utility model belongs to the technical field of preserved flower color preservation boxes, specifically, it relates to an ultraviolet-blocking preserved flower color preservation box. Background Technology

[0002] Preserved flowers are fresh flowers processed using special techniques to maintain their natural shape and color for a long time. However, ultraviolet (UV) radiation is one of the main factors causing fading and aging of preserved flowers. UV-blocking color-preserving boxes are devices specifically designed to protect preserved flowers from UV damage. They block UV rays through physical or chemical means while maintaining a suitable temperature and humidity environment to extend the lifespan of the preserved flowers. Traditional UV-blocking technologies mainly include: UV-absorbing coating: applying UV absorbers (such as titanium dioxide, zinc oxide, etc.) to the surface or interior of the box to absorb or reflect UV rays. Filter glass / acrylic: using a transparent panel made of special materials to filter out specific wavelengths of UV radiation (such as UVA 320-400nm, UVB 280-320nm). Sealed environment control: reducing air exchange and lowering the oxidation reaction rate, indirectly slowing down the fading process.

[0003] While current technologies can protect preserved flowers to some extent, significant problems remain: Ultraviolet (UV) radiation is a key factor causing fading. In everyday environments, UV rays from sunlight are ubiquitous; even indoors, some UV rays can penetrate through window glass. Ordinary boxes or containers offer almost no protection against UV rays. Prolonged exposure to such environments causes photochemical reactions in the pigment molecules of preserved flowers, leading to structural damage and gradual color fading. Light intensity also significantly impacts the preservation of preserved flowers. Excessive light not only contains large amounts of UV radiation but also generates heat, accelerating internal chemical reactions and promoting aging and fading. Besides light, humidity and temperature are also crucial for preservation. High humidity levels can lead to mold growth, causing mold and rot. Conversely, low humidity makes the flowers dry and fragile, causing petals to fall off easily. Significant temperature fluctuations can also damage preserved flowers; the effects of thermal expansion and contraction can deform the internal structure, affecting their integrity. In terms of structural design and functionality, existing preserved flower color preservation boxes also have many shortcomings. Most color preservation boxes adopt a simple box structure with poor sealing performance, failing to effectively prevent the entry of outside air, dust, and moisture. Their light control methods are simplistic, often relying solely on an opaque box to block light, lacking precise adjustment mechanisms. Moreover, these color preservation boxes cannot provide targeted protection when facing complex indoor and outdoor lighting environments, such as sunlight from different directions. Furthermore, traditional color preservation boxes perform poorly in terms of maintenance and expandability; desiccant replacement is difficult, cleaning is inconvenient, and they struggle to meet the diverse display needs of users. Utility Model Content

[0004] In view of this, the present invention provides an ultraviolet-blocking preserved flower color preservation box, which solves the drawback of traditional preserved flower color preservation boxes in terms of convenient light adjustment, and achieves efficient ultraviolet blocking while avoiding damage to preserved flowers from excessive light.

[0005] This utility model is implemented as follows:

[0006] This utility model provides an ultraviolet-blocking preserved flower color preservation box, which includes:

[0007] The enclosure is a rectangular cavity structure formed by the front panel, rear panel, top panel, bottom panel and two side panels. The front panel is designed to be openable and closable.

[0008] The louver structure is installed on the inner or outer side of at least one side panel and includes multiple parallel blades. The blades are long and thin, and ultraviolet absorbers are uniformly dispersed inside them.

[0009] The angle adjustment mechanism includes a lever located outside the housing and a linkage rod penetrating the side plate. The linkage rod is hinged to the end of all blades through a connector. The swing of the lever drives the linkage rod to move or rotate axially, thereby synchronously adjusting the tilt angle of the blades.

[0010] A sealing assembly, located at the contact edge between the front panel and the housing, includes a magnetic strip embedded in the front panel and a metal adsorption strip on the housing frame, for achieving airtight closure.

[0011] The technical advantages of this UV-blocking preserved flower color-preserving box are as follows: Through the mechanical linkage of the louver structure and angle adjustment mechanism, dynamic UV blocking without electronic components is achieved, avoiding the complexity and high cost of intelligent control systems. The sealing assembly ensures a stable microenvironment inside the box, delaying the oxidation and fading of the preserved flowers.

[0012] The surface or interior of the enclosure is coated with a UV absorber (such as titanium dioxide, zinc oxide, etc.) to absorb or reflect ultraviolet rays.

[0013] Based on the above technical solution, the ultraviolet-blocking preserved flower color-preserving box of this utility model can be further improved as follows:

[0014] The louvered structures are symmetrically installed on the two side panels of the box, and the angles of the two sets of louvered structures can be adjusted independently.

[0015] Furthermore, each side of the louver structure is equipped with an independent angle adjustment mechanism, the angle adjustment mechanism including:

[0016] Lever: The left and right levers are located at both ends of the housing;

[0017] Linkage rods: The linkage rods on both sides are parallel but do not interfere with each other, and pass through the shaft holes of the corresponding side plates respectively;

[0018] Connector: A shaft that connects only to the blades on this side.

[0019] The bearings of the two linkage rods are staggered by more than 10mm to avoid motion interference. An isolation baffle is added to the inside of the window on the side plate to block the mechanical transmission of the linkage mechanism on the other side. The left lever is located at the left front edge of the top plate, and the right lever is located at the right rear edge of the top plate. Their movement trajectories are spatially separated, with a minimum distance of ≥50mm.

[0020] Furthermore, the blade has an arc-shaped convex cross-section with the convex surface facing the inside of the housing, and its length is 80% to 90% of the height of the side plate; both ends of the blade are rotatably connected to the mounting groove of the side plate through a rotating shaft, and the axis of the rotating shaft is perpendicular to the length direction of the blade; the blade tilt angle adjustment range is 0°-45°.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the convex surface design of the curved blades enhances ultraviolet reflection, and the spacing of 8-12mm balances the needs of shading and ventilation. The rotating shaft enables smooth blade rotation, and the adjustment range of 0° to 45° covers most lighting conditions.

[0022] Furthermore, the linkage rod is a metal round rod, which is set parallel to the lower edge of the window on the side plate, and its two ends are rotatably connected to the side plate through bearings;

[0023] The connector is an "L"-shaped metal link, one end of which is vertically fixed to the linkage rod, and the other end is hinged to the blade shaft by a pin.

[0024] The lever is T-shaped, with its vertical rod passing through a hole in the side plate and fixedly connected to the end of the linkage rod, and its horizontal rod protruding from the surface of the housing.

[0025] Furthermore, the front panel has inwardly recessed sealing grooves around its perimeter, and strip-shaped silicone sealing rings are embedded in the sealing grooves.

[0026] The opening frame of the housing has a raised pressing ridge at the position corresponding to the sealing groove. The pressing ridge has a semi-circular cross section and is interference-fitted with the silicone sealing ring.

[0027] Furthermore, the upper surface of the base plate is provided with a grid-like protrusion for ventilation and moisture protection when placing preserved flowers;

[0028] A reflective film is pasted on the inner side of the top plate. The reflective film is made of PET material and has a microprism array structure on its surface to uniformly scatter the light entering the box.

[0029] Furthermore, the inner side of the box is also equipped with a detachable light-blocking curtain, which is made of flexible fabric with a UV blocking rate of ≥90%.

[0030] Furthermore, the inner wall of the box is fitted with an EVA foam layer, and the surface of the foam layer has honeycomb-shaped grooves; the bottom of the base plate is provided with four hemispherical rubber suction cups.

[0031] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the honeycomb grooves of the 3-5mm thick EVA foam layer absorb vibration energy, reducing the transportation damage rate by 80%; the rubber suction cup is non-slip and shock-absorbing, and adaptable to different tabletop materials.

[0032] Furthermore, the front panel and top panel of the enclosure are made of high-transmittance acrylic material, while the rear panel and bottom panel are made of frosted or atomized opaque material; rectangular windows are opened in the middle of the two side panels, and the edges of the windows are provided with mounting grooves for fixing the louver structure.

[0033] The transparent front and top panels facilitate viewing, while the opaque back and bottom panels reduce UV reflection from the back. Rectangular windows on the side panels provide installation space for the blinds, and mounting slots ensure structural stability.

[0034] Compared with existing technologies, the beneficial effects of the ultraviolet-blocking preserved flower color-preserving box provided by this utility model are:

[0035] This invention utilizes a UV absorber, such as nano-titanium dioxide, uniformly dispersed inside the louver blades. This absorber can absorb UV radiation through electron transitions. In practical applications, when UV radiation hits the blades, the electrons in the nano-titanium dioxide absorb the UV energy and undergo transitions, thus converting the UV energy into other forms of energy, effectively reducing the damage of UV radiation to preserved flowers.

[0036] The curved, convex design of the leaves further enhances the UV blocking effect. When UV rays strike the convex surface of the leaves at a certain angle of incidence, most of the UV rays are reflected due to the optical properties of the convex surface. This reflection works in conjunction with the absorption effect of the UV absorber, reducing the amount of UV rays reaching the preserved flower from multiple levels.

[0037] The angle adjustment mechanism allows the leaves to be infinitely adjusted within a range of 0° to 45°. In low-light conditions, opening the leaves to 45° allows some visible light (500-700nm) to enter the enclosure, maintaining good viewing brightness and allowing users to clearly appreciate the beauty of the preserved flowers. In strong-light conditions, closing the leaves to 0° effectively blocks ultraviolet rays while preventing damage from excessive light. This function of flexibly adjusting the leaf angle according to different lighting conditions satisfies viewing needs while protecting the preserved flowers.

[0038] The left and right louvers are independently controlled via a split-type linkage mechanism. This design allows the color-preserving box to better adapt to complex lighting environments. This further enhances the protection of the preserved flowers, ensuring they are always in a suitable lighting environment regardless of the time or direction of light.

[0039] Employing a mechanical transmission system using metal linkage rods and "L"-shaped connectors, electronic components are eliminated. This design demonstrates exceptional durability in high humidity environments (>85%), exhibiting no failures after 1000 consecutive adjustments. Compared to electric adjustment systems, costs are reduced by 70%, and lifespan is extended by 3 times. This not only lowers manufacturing and maintenance costs but also improves reliability in harsh environments, which is of great significance for preserved flower color retention boxes requiring long-term stable operation.

[0047] like Figure 1 The image shown is a first embodiment of a UV-blocking preserved flower color-preserving box provided by this utility model. In this embodiment, it includes:

[0048] The box 10 is formed by the front panel 11, the rear panel 12, the top plate 13, the bottom plate 14 and the two side panels 15 to form a cuboid cavity structure. The front panel 11 is designed to be openable and closable.

[0052] like Figure 2 , Figure 3 As shown, in the above technical solution, the louver structure 20 is symmetrically installed on the two side plates 15 of the box body 10, and the angles of the two sets of louver structures 20 can be adjusted independently.

[0061] Furthermore, in the above technical solution, the linkage rod 32 is a metal round rod, which is set parallel to the lower edge of the window of the side plate 15, and its two ends are rotatably connected to the side plate 15 through bearings;

[0062] The connector 33 is an "L"-shaped metal connecting rod, one end of which is vertically fixed to the linkage rod 32, and the other end is hinged to the rotating shaft of the blade 21 by a pin.

[0063] The lever 31 is T-shaped, with its vertical rod passing through the hole in the side plate 15 and fixedly connected to the end of the linkage rod 32, and its horizontal rod protruding from the surface of the housing 10.

[0064] Furthermore, in the above technical solution, the front panel 11 has inwardly recessed sealing grooves around its perimeter, and strip-shaped silicone sealing rings are embedded in the sealing grooves.

[0065] The opening frame of the housing 10 has a raised pressing ridge corresponding to the sealing groove. The pressing ridge has a semi-circular cross section and is interference-fitted with the silicone sealing ring.

[0066] Furthermore, in the above technical solution, the upper surface of the base plate 14 is provided with a grid-like protrusion for ventilation and moisture prevention when placing the preserved flowers;

[0067] A reflective film is pasted on the inside of the top plate 13. The reflective film is made of PET material and has a micro prism array structure on its surface, which is used to evenly scatter the light entering the box 10.

[0068] Furthermore, in the above technical solution, the inner side of the housing 10 is also provided with a detachable light-blocking curtain, which is made of flexible fabric with a UV blocking rate of ≥90%.

[0069] Furthermore, in the above technical solution, the inner wall of the box 10 is fitted with an EVA foam layer, and the surface of the foam layer is provided with honeycomb-shaped grooves; the bottom of the base plate 14 is provided with four hemispherical rubber suction cups.

[0070] Furthermore, in the above technical solution, the front panel 11 and top panel 13 of the housing 10 are made of high light transmittance acrylic material, and the rear panel 12 and bottom panel 14 are made of frosted or atomized opaque material; rectangular windows are opened in the middle of the two side panels 15, and the edges of the windows are provided with mounting grooves for fixing the louver structure 20.

[0071] When displaying, place the transparent side of the box 10 facing the viewer and the opaque side against the light.

[0072] Specifically, the principle of this utility model is as follows:

[0073] Ultraviolet blocking mechanism:

[0074] The blades employ a multi-layered composite barrier, with the UV absorbers within them working based on their molecular structure. Taking nano-titanium dioxide as an example, electrons in its crystal structure, excited by UV photons, can transition from the valence band to the conduction band, absorbing UV energy in the process. This UV energy is converted into the energy required for electron transitions, thus reducing UV transmission. The absorption peak of nano-titanium dioxide is around 385nm, effectively absorbing most of the UV wavelength. The blade's convex design utilizes the principle of light reflection. When light strikes the convex surface, reflection occurs according to the law of reflection. By optimizing the blade's radius of curvature to 15mm, high reflectivity (>85%) can be achieved for UV rays at specific incident angles (e.g., 30°). This is because the convex shape ensures a specific geometric relationship between the incident and reflection angles of light, reflecting most of the UV radiation. The blade spacing is related to the principle of light diffraction. When light passes through a slit or obstacle, significant diffraction occurs if the size of the slit or obstacle is similar to or smaller than the wavelength of the light. In this invention, the blade spacing is set to 8-12mm, while the ultraviolet wavelength range is 280-400nm. This spacing prevents the ultraviolet light from meeting the conditions for significant diffraction, thereby reducing the possibility of ultraviolet light bypassing the blades and entering the box through diffraction. By utilizing the absorption of the ultraviolet absorber, the reflection of the convex surface, and the control of diffraction through reasonable spacing, a multi-layered composite ultraviolet blocking effect is achieved.

[0075] Mechanical transmission optimization:

[0076] In terms of torque transmission design, the length of the lever is set reasonably so that the fingers can drive multiple blades with a small operating force, while the diameter of the linkage rod meets the yield strength requirements.

[0077] By selecting POM plastic with a low coefficient of friction as the shaft material and chrome-plating the pins of the connectors, friction loss is effectively controlled and the durability of the mechanical transmission system is improved.
