Titanium alloy antibacterial pot

Abstract

This utility model relates to the field of catering products technology and discloses a titanium enamel antibacterial cookware, including a tableware body. The tableware body has a titanium alloy base layer inside, and a sintered titanium enamel layer is provided on the inner surface of the titanium alloy base layer. Antibacterial particles are uniformly dispersed on the inner side of the sintered titanium enamel layer, and an outer ceramic layer is provided on the outer side of the titanium alloy base layer. The titanium alloy base layer provides a high-strength support skeleton, and the sintered titanium enamel layer on its surface forms a dense protective barrier. The antibacterial particles (nano-titanium dioxide and silver particles) embedded in this layer constitute the core antibacterial mechanism. When the tableware is exposed to natural light or artificial light, the antibacterial particles trigger a photocatalytic reaction, continuously releasing reactive oxygen free radicals and silver ions, directly destroying bacterial cell membranes and blocking DNA replication, achieving an ultra-high broad-spectrum antibacterial rate. This design breaks through the limitation of traditional coatings being easily worn off. The Mohs hardness of the sintered titanium enamel layer ensures that the antibacterial particles are firmly encapsulated. Even with long-term wear and tear, the inner particles can still slowly release antibacterial factors.

Description

Technical Field

[0001] This utility model relates to the field of catering supplies technology, and more specifically, to a titanium enamel antibacterial cookware. Background Technology

[0002] Tableware is a general term for tools used for cooking, serving, and consuming food, encompassing plates, bowls, chopsticks, knives, forks, spoons, cups, etc. It is an important carrier of food culture. According to function, it can be divided into eating utensils (such as bowls and plates), eating utensils (such as chopsticks, forks and spoons), drinking utensils (such as cups), and auxiliary utensils (such as placemats and serving chopsticks). Modern tableware emphasizes the combination of practicality and aesthetics, and is made of various materials, including ceramics, glass, metal (stainless steel), wood, or environmentally friendly materials. It must meet requirements such as safety and hygiene, high temperature resistance, and easy cleaning.

[0003] For example, a ceramic tableware with strong self-cleaning properties, disclosed in publication number CN212815670U, includes a ceramic tableware body. The ceramic tableware body includes a base layer, a wear-resistant layer on the surface of the base layer, an anti-crack layer fixedly connected to the inner wall of the base layer, a heat insulation layer fixedly connected to the inner wall of the anti-crack layer, a heat preservation layer fixedly connected to the inner wall of the heat insulation layer, an antibacterial layer fixedly connected to the inner wall of the heat preservation layer, and a self-cleaning layer fixedly connected to the inner wall of the antibacterial layer. The base layer is made of ceramic, the wear-resistant layer is made of a corundum wear-resistant coating, and the anti-crack layer is made of an anti-crack film. This utility model, by incorporating a base layer, a wear-resistant layer, an anti-crack layer, a heat insulation layer, a heat preservation layer, an antibacterial layer, a self-cleaning layer, titanium dioxide sol, and a nano self-cleaning glaze, solves the problem of existing ceramic tableware having poor self-cleaning properties and requiring a lot of detergent to clean. This ceramic tableware possesses the advantage of strong self-cleaning properties and is worthy of promotion.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that although the device can enhance self-cleaning ability to a certain extent, traditional tableware lacks effective antibacterial and sterilization capabilities in actual use, and has certain defects in use. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a titanium enamel antibacterial cookware, which has the advantages of antibacterial and sterilization.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a titanium enamel antibacterial cookware, comprising a tableware body, wherein a titanium alloy base layer is disposed inside the tableware body, a sintered titanium enamel layer is disposed on the inner surface of the titanium alloy base layer, antibacterial particles are uniformly dispersed on the inner side of the sintered titanium enamel layer, and an outer ceramic layer is disposed on the outer side of the titanium alloy base layer.

[0007] As a preferred embodiment of this invention, the sintered titanium enamel layer is made of a composite material of titanium and glass.

[0008] As a preferred technical solution of this utility model, the antibacterial particles are made of titanium dioxide and silver particles, which can continuously release antibacterial ions through photocatalytic reaction.

[0009] As a preferred technical solution of this utility model, the outer ceramic layer is located on the outermost layer of the tableware body, which plays a role in heat insulation and heat preservation.

[0010] As a preferred embodiment of this utility model, handles are fixedly installed on both sides of the tableware body, and the surface of the handles is coated with a thermochromic coating.

[0011] As a preferred embodiment of this utility model, a base support block is fixedly installed at the bottom of the tableware body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a high-strength support skeleton through a titanium alloy base layer, and a dense protective barrier is formed by a sintered titanium enamel layer on its surface. The antibacterial particles (nano titanium dioxide and silver particles) embedded in this layer constitute the core antibacterial mechanism. When the tableware comes into contact with natural light or artificial light, the antibacterial particles trigger a photocatalytic reaction, continuously releasing active oxygen free radicals and silver ions, directly destroying bacterial cell membranes and blocking DNA replication, achieving an ultra-high broad-spectrum antibacterial rate. This design breaks through the limitation of traditional coatings being easy to wear off. The Mohs hardness of the sintered titanium enamel layer ensures that the antibacterial particles are firmly encapsulated. Even with long-term wear and tear, the inner particles can still slowly release antibacterial factors. At the same time, the titanium enamel material gives the tableware body superhydrophobic properties, making it difficult for oil stains to adhere. It can be self-cleaned by rinsing with water, completely solving the problem of bacterial growth caused by surface residues in traditional tableware.

[0014] 2. This utility model uses an outer ceramic layer to cover the outside of a titanium alloy base. The low thermal conductivity of ceramic blocks heat transfer, effectively preventing burns and maintaining food temperature. The handle integrates a thermochromic coating that changes from red to transparent when exposed to high temperatures (60℃±5℃), providing real-time warnings to users of the risk of burns. It is especially suitable for use by children and the elderly. The base block is integrally formed with the bottom of the tableware body, and an anti-slip silicone pad is added to the bottom to prevent the tableware from sliding and tipping over. Its lifting design ensures that the tableware body is suspended, isolating tabletop contamination and enhancing public health safety. All structures work together to strengthen the system. The outer ceramic layer improves heat insulation comfort, the handle provides active safety protection, and the base block combines stability and stain resistance, ultimately forming a multifunctional tableware system that integrates long-lasting antibacterial properties, temperature management, and human-computer interaction.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a titanium enamel antibacterial cookware, including a tableware body 1, a titanium alloy base layer 2 inside the tableware body 1, a sintered titanium enamel layer 3 on the inner surface of the titanium alloy base layer 2, antibacterial particles 4 evenly dispersed on the inner side of the sintered titanium enamel layer 3, and an outer ceramic layer 5 on the outer side of the titanium alloy base layer 2.

[0022] By setting up the tableware body 1, the basic shape and supporting structure of the tableware can be provided, integrating the titanium alloy base layer 2, sintered titanium enamel layer 3, antibacterial particles 4, outer ceramic layer 5, handle 6 and base block 7, to realize its overall function as antibacterial tableware.

[0023] Among them, the sintered titanium enamel layer 3 is made of a composite material of titanium and glass.

[0024] By setting the sintered titanium enamel layer 3, a high-hardness, corrosion-resistant and dense composite material layer can be formed on the inner surface of the titanium alloy base layer 2, which firmly covers the antibacterial particles 4, provides a durable physical barrier, and gives the surface superhydrophobic properties for easy cleaning.

[0025] Among them, the antibacterial particles 4 are made of titanium dioxide and silver particles, which can continuously release antibacterial ions through photocatalytic reaction.

[0026] By setting antibacterial particles 4, they can be uniformly dispersed in the sintered titanium enamel layer 3. Utilizing the photocatalytic effect of titanium dioxide under light and the release of silver particles, antibacterial factors (such as active oxygen and silver ions) are continuously generated, effectively killing or inhibiting bacteria on the contact surface and achieving long-lasting self-antibacterial effect.

[0027] Among them, the outer ceramic layer 5 is located on the outermost layer of the tableware body 1, which plays a role in heat insulation and heat preservation.

[0028] By applying an outer ceramic layer 5, the outer side of the titanium alloy base layer 2 can be covered, which significantly reduces the thermal conductivity of the tableware body 1, improves the heat insulation effect, improves the thermal comfort of the tableware hand grip (especially when holding hot food), prevents burns, and helps maintain the food temperature.

[0029] The tableware body 1 has handles 6 fixedly installed on both sides, and the surface of the handles 6 is coated with thermochromic paint.

[0030] The handle 6 allows users to easily grip and pick up the tableware body 1, improving ease of use and human-computer interaction. It is especially suitable for larger tableware. The thermochromic coating on the surface of the handle 6 can change color (e.g., from red to colorless) when the handle 6 comes into contact with high temperature (e.g., 60℃±5℃), providing users with intuitive and immediate temperature warnings and effectively preventing the risk of burns.

[0031] The bottom of the tableware body 1 is fixedly installed with a base support block 7.

[0032] The base block 7 can be fixedly connected to the bottom of the tableware body 1, providing a stable support surface to prevent the tableware from shaking or tipping over when placed, and ensuring that the tableware is placed stably on the table.

[0033] The working principle and usage process of this utility model are as follows: Through the structural integration of the tableware body 1, multi-functional collaborative operation is achieved: When the tableware comes into contact with food, the antibacterial particles 4 (nano-titanium dioxide and silver particles) in the sintered titanium enamel layer 3 trigger a photocatalytic reaction under light, continuously releasing active oxygen and silver ions, directly destroying bacterial cell membranes and inhibiting their proliferation (antibacterial rate >99%), while the titanium alloy base layer 2 provides high-strength support; at the same time, the outer ceramic layer 5 wraps around the outside of the titanium alloy base layer 2, using the low thermal conductivity of ceramics to block heat transfer, prevent burns and maintain food temperature; the thermochromic coating on the handle 6 automatically changes color when exposed to high temperatures of 60℃±5℃, warning users of the risk of burns; the bottom support block 7 firmly supports the bottom of the tableware body 1, preventing tipping and isolating tabletop contamination; finally, the superhydrophobic properties of the sintered titanium enamel layer 3 make it difficult for oil stains to adhere, achieving self-cleaning with water, forming a highly efficient tableware system that integrates long-lasting antibacterial, heat insulation protection, safety warning, and stable anti-fouling.
