Description

Technical Field

[0001] This utility model relates to the field of titanium alloy cups, and more specifically, to a titanium cup inner wall treatment structure with an antibacterial coating. Background Technology

[0002] Titanium alloy cups, representing modern high-end cups, are meticulously crafted using titanium alloy as the primary material. Titanium alloy combines high strength with lightweight properties, making the cups sturdy, durable, and easy to carry. Simultaneously, it possesses excellent corrosion resistance, resisting the erosion of various acids and alkalis, and is not prone to rusting or discoloration even after prolonged use. Furthermore, titanium alloy has good biocompatibility, is safe and non-toxic, and will not produce harmful substances when used to hold beverages, providing people with a healthy and high-quality drinking experience.

[0003] Due to the complex daily usage environment, bacteria can easily grow on the inner wall of titanium cups. The surface of ordinary titanium cups is relatively smooth and lacks effective antibacterial mechanisms, allowing bacteria to easily adhere and multiply under suitable conditions. When people use such titanium cups to drink beverages, these bacteria may enter the body, increasing health risks, especially in people with weakened immune systems, potentially causing gastrointestinal discomfort and other illnesses.

[0004] Existing titanium cup inner wall coatings have poor adhesion. Even when an antibacterial coating is applied to the inner wall, the bonding between the coating and the inner wall is not strong enough due to the surface characteristics of titanium alloy. During use, such as frequent cleaning, impacts, or temperature changes, the coating is prone to peeling off. Once the coating peels off, not only is the antibacterial function lost, but the detached coating fragments may also mix into the beverage, posing a potential health hazard.

[0005] Therefore, we have made improvements to this by proposing a titanium cup inner wall treatment structure with an antibacterial coating. Utility Model Content

[0024] To address the technical problems in the background art, the following structure for treating the inner wall of a titanium cup with an antibacterial coating is provided: Combination Figure 1 - Figure 4As shown, the titanium cup inner wall treatment structure with antibacterial coating provided by this utility model includes a titanium cup body 1, a cup lid 2 threadedly connected to the upper side of the titanium cup body 1, and a microstructure layer 3 provided on the inner wall of the titanium cup body 1. The surface of the microstructure layer 3 is coated with a transition layer 4, and the surface of the transition layer 4 is coated with an antibacterial coating 5. A connecting groove 6 is opened inside the cup lid 2, and a sealing ring 7 is engaged inside the connecting groove 6.

[0025] In this embodiment, a lid 2 is threaded onto the upper side of the titanium cup body 1, facilitating opening and closing while ensuring a good seal. A microstructure layer 3 is formed on the inner wall of the titanium cup body 1, with a transition layer 4 uniformly coated on its surface. An antibacterial coating 5 covers the transition layer 4. This multi-layered structure works synergistically to give the inner wall of the titanium cup excellent antibacterial properties and stability. Furthermore, a sealing ring 7 is engaged in a connecting groove 6 inside the lid 2, further enhancing the sealing effect and effectively preventing beverage leakage and the intrusion of external bacteria.

[0026] As a preferred embodiment, the titanium cup body 1 is made of high-purity titanium alloy to ensure lightweight and corrosion resistance.

[0027] In this embodiment: High-purity titanium alloy possesses unique physical and chemical properties. Its relatively low density makes the resulting titanium cup lightweight and easy for users to carry daily, whether for travel, exercise, or office use, without adding much burden. Simultaneously, titanium alloy exhibits excellent corrosion resistance, resisting the erosion of various common liquids such as acidic fruit juices, alkaline teas, and drinking water. Even during long-term use, it is not prone to chemical reactions that cause rust or discoloration, greatly extending the lifespan of the titanium cup and providing users with a durable and reliable user experience.

[0028] In a preferred embodiment, the microstructure layer 3 is a uniformly distributed micron-sized groove and protrusion structure, formed by laser engraving or chemical etching technology.

[0029] In this embodiment, laser engraving technology can create delicate microstructures on the inner wall surface of the titanium cup with extremely high precision. The processing is precise and controllable, ensuring that the size and distribution of the grooves and protrusions are uniform. These micron-sized grooves and protrusions greatly increase the surface area of ​​the inner wall of the titanium cup, providing more bonding sites for the subsequent coating adhesion, which helps to improve the bonding strength between the coating and the inner wall, thereby enhancing the stability and reliability of the entire inner wall treatment structure.

[0030] As a preferred embodiment, the transition layer 4 is made of titanium alloy or organosilicon compound, which can effectively improve the adhesion between the antibacterial coating 5 and the microstructure layer 3 and enhance the stability of the overall structure.

[0031] In this embodiment: when the transition layer 4 is made of titanium alloy, its material is similar to that of the titanium cup body 1, resulting in good compatibility. It can seamlessly integrate with the microstructure layer 3, forming a naturally transitional interface, effectively enhancing the adhesion between the antibacterial coating 5 and the microstructure layer 3. Meanwhile, the organosilicon compound possesses unique chemical properties; it can form a chemically bonded layer on the surface of the microstructure layer 3, generating a strong chemical adsorption effect with the antibacterial coating 5, further improving the coating's adhesion. By setting such a transition layer 4, the antibacterial coating 5 can be more firmly attached to the inner wall of the titanium cup, making it less prone to detachment during use. This enhances the stability of the entire inner wall treatment structure of the titanium cup, ensuring its long-term excellent antibacterial performance.

[0032] As a preferred embodiment, the antibacterial coating 5 is a nano-silver ion or copper ion antibacterial material, which is coated by physical vapor deposition or chemical plating technology.

[0033] In this embodiment: both nano-silver ions and copper ions possess strong antibacterial activity. They can disrupt the cell membrane structure of bacteria and interfere with bacterial metabolic processes, thereby inhibiting bacterial growth and reproduction. Physical vapor deposition technology can deposit antibacterial materials in atomic or molecular form on the surface of transition layer 4 in a vacuum environment, forming a uniform, dense, and highly pure antibacterial coating, ensuring the stability and durability of the antibacterial effect. Chemical plating technology deposits antibacterial materials on the surface of transition layer 4 through a chemical reaction. This method can achieve uniform coating on surfaces with complex shapes, and the adhesion between the coating and the substrate is strong, further improving the quality and performance of the antibacterial coating 5.

[0034] In a preferred embodiment, the antibacterial coating 5 has a uniform thickness, covers the entire surface of the transition layer 4, and is tightly bonded to the transition layer 4.

[0035] In this embodiment, the uniformly thick antibacterial coating 5 ensures that the content and distribution of antibacterial components are consistent across the entire inner wall surface of the titanium cup, thereby providing stable and reliable antibacterial performance and avoiding situations where uneven coating thickness leads to poor antibacterial effects in some areas. Complete coverage of the transition layer 4 prevents bacterial growth in uncoated areas, ensuring good antibacterial capabilities throughout the entire inner wall. Furthermore, the tight bond with the transition layer 4 ensures that the antibacterial coating 5 will not easily detach during use. Even after frequent cleaning, impacts, or temperature changes, it remains firmly attached to the inner wall, continuously exerting its antibacterial effect and providing users with long-term and effective health protection.

[0036] As a preferred embodiment, the sealing ring 7 is made of food-grade silicone material and fits tightly against the edge of the mouth of the titanium cup body 1.

[0037] In this embodiment, the food-grade silicone material is non-toxic, odorless, and chemically stable. It will not chemically react with the beverage inside the cup, nor will it release harmful substances, ensuring the safety and hygiene of the beverage consumed by the user. Simultaneously, the silicone material has good elasticity and flexibility, allowing it to fit tightly against the edge of the titanium cup body, forming a reliable sealing barrier that effectively prevents leakage of the beverage inside the cup, avoiding inconvenience and waste caused by spillage. Furthermore, the tight fit also prevents bacteria, dust, and other impurities from the outside air from entering the cup, further ensuring the cleanliness and hygiene of the beverage inside, providing users with a healthy and convenient drinking environment.

[0038] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model.
