The present application will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] like Figure 1 and Figure 2 As shown in the preferred embodiment of the present invention, an antibacterial glass cover includes: a cover body 1 and a reinforcing frame 2; the reinforcing frame 2 covers the periphery of the cover body 1.
[0023] The cover plate body 1 includes a glass substrate 101, a composite antibacterial layer 102, and a transparent protective layer 103. The composite antibacterial layer 102 is disposed on the top of the glass substrate 101, and the transparent protective layer 103 is disposed on the top of the composite antibacterial layer 102.
[0024] like Figure 3 As shown, the composite antibacterial layer 102 includes a plurality of photocatalytic antibacterial layers 1021 and a plurality of silver ion doped layers 1022, wherein the photocatalytic antibacterial layers 1021 and the silver ion doped layers 1022 are stacked alternately from top to bottom; the transparent protective layer 103 is a hydrophobic material layer.
[0025] like Figure 4 and Figure 5 As shown, the reinforced frame 2 includes a frame body 201 and a retaining edge 202; the retaining edge 202 is provided at both the top and bottom of the frame body 201, and the edge of the cover plate body 1 is embedded between the retaining edges 202 at the top and bottom of the frame body 201.
[0026] The glass substrate 101 serves as a basic support layer, providing mechanical strength and light transmittance to the glass cover. The composite antibacterial layer 102 kills or inhibits surface microorganisms through a dual antibacterial mechanism of photocatalysis and silver ions. The transparent protective layer 103 covers the composite antibacterial layer, preventing external contamination and enhancing self-cleaning ability. The reinforcing frame 2 covers the edge of the cover body 1 and fixes the glass substrate 101 by the top and bottom clips 202.
[0027] As a preferred embodiment of this utility model, it may also have the following additional technical features:
[0028] like Figure 3 As shown, in a preferred embodiment, the photocatalytic antibacterial layer 1021 is a nano-titanium dioxide layer, the silver ion doped layer 1022 is a porous silica-based carrier layer, and silver ions are adsorbed within the porous structure of the porous silica-based carrier.
[0029] The nano-titanium dioxide of the photocatalytic antibacterial layer 1021 generates active oxygen under light, decomposing bacterial cell membranes and organic matter. It has long-lasting antibacterial effect and leaves no chemical residue, making it environmentally friendly and safe. The porous silica-based carrier of the silver ion doped layer 1022 adsorbs silver ions and slowly releases them, continuously inhibiting bacteria in the dark. Silver ions also have broad-spectrum antibacterial properties, with an antibacterial rate of over 99%.
[0030] like Figure 3 As shown, in a preferred embodiment, the photocatalytic antibacterial layer 1021 and the silver ion doped layer 1022 in the composite antibacterial layer 102 are stacked alternately from top to bottom in the following order: photocatalytic antibacterial layer 1021, silver ion doped layer 1022.
[0031] The photocatalytic antibacterial layer 1021 and the silver ion doped layer 1022 are arranged alternately to form a gradient antibacterial effect, expanding the depth and range of action.
[0032] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the reinforcing frame 2 includes a sealing strip 203, which is disposed between the reinforcing frame 2 and the cover plate body 1. The sealing strip 203 fills the gap between the frame body 201 and the cover plate body 1 to achieve a seal, preventing liquid or contaminants from seeping into the interlayer and causing silver ion loss or antibacterial layer peeling.
[0033] In a preferred embodiment, the sealing strip 203 is made of silicone rubber. Silicone rubber has a wide temperature range, does not harden or crack at extreme temperatures, is suitable for high-temperature disinfection or cold environments, is resistant to ultraviolet rays and ozone, is also resistant to chemical corrosion, does not easily age with long-term outdoor use, and does not react with common cleaning agents such as alcohol and disinfectants, thus avoiding swelling or degradation.
[0034] like Figure 4As shown, in a preferred embodiment, the reinforced frame 2 includes a detachable cover plate 204, which is magnetically attached to the top of the reinforced frame 2, making it easy to clean or maintain the internal structure after disassembly, and also providing dust and water protection when not in use.
[0035] The working principle of this utility model is as follows:
[0036] The nano-titanium dioxide (TiO2) in the photocatalytic antibacterial layer generates reactive oxygen species (ROS) under light irradiation. ROS can degrade pollutants such as bacterial residues and fingerprint grease, and cut off the bacterial nutrient source.
[0037] The porous silica carrier with silver ion doped layer adsorbs silver ions, which are then slowly released to achieve a bactericidal and antibacterial effect.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
