DETAILED DESCRIPTION OF THE INVENTION

[0019] The applicant first explains here that in this specification, including the embodiments described below and the claims of the scope of patent application, the nouns related to directionality are based on the direction in the diagram. Secondly, in the embodiments and drawings that will be introduced below, the same element numbers represent the same or similar elements or their structural features.

[0020] Please refer to FIGS. 1-4 first, the catalyst carrier structure of the first embodiment of the present invention comprises a central axis 10 and a plurality of fibers 20.

[0021] The central axis 10 can be a solid structure or a virtual imaginary central axis. In this embodiment, it is a solid columnar structure.

[0022] The surface of each fiber 20 is coated with a catalyst. The fibers 20 are centered on the central axis 10, and are arranged around the central axis 10 radially outward along the axial direction of the central axis 10. The fibers 20 are independent and separate fibers arranged on the central axis 10. These fibers can be in the form of straight strips or spirals, etc. These fibers 20 can be made of carbon fiber, glass fiber, or polyester. The diameter of each fiber is about 10 μm-50 μm, and its length is 1˜200 mm. If the diameter of the fibers 20 is too small, it may not be able to support the weight of the fibers themselves and sag, If the diameter of fibers 20 is too large, it will take up too much space, increase the overlap between fibers in the space, reduce the circulation of light and air, and lose the function of three-dimensional dispersion. The length of the fibers themselves should not be too long, because too long fibers cannot support their own weight and will sag. Sagging will increase the overlap or shading between the fibers, so it is impossible to form a radial three-dimensional dispersion when setting.

[0023] The catalyst mentioned in this case can be nano-silver catalyst or photocatalyst, or a catalyst containing three precious metals of platinum, palladium and rhodium, or tin-iron oxide, etc. Tin-iron oxide is a postdoctoral researcher in the Laboratory of Nanomaterials and Nanostructures led by Professor Lu Shiyuan of Tsinghua University. Li Guanting researches the application of “tin-iron oxide (SnFe2O4)”. It was found to rapidly decompose organic matter in sewage (the third fastest degradation rate known in the literature). The paper was published in the international academic journal “Journal of Material Chemistry A” in May 2019. In this example, a photocatalyst is used as an illustrative example, but it is not limited to this.

[0024] In the first embodiment of the present invention, the central axis 10 is a helical central axis. Therefore, when the fibers 20 are arranged on the central axis 10, they also exhibit a helical distribution along with the helical rotation of the central axis 10. Of course, the central axis is not limited to a spiral shape, but can also be a straight column. The distribution of these fibers 20 is not limited to a spiral shape, but can also be a hierarchical arrangement. That is, at the position of the same layer, with the central axis as the center, complex fibers are arranged in radial radiation, and multiple layers are continuously arranged from one end of the central axis 10 to the other end. Or these fibers can also be centered on the central axis 10, radial radiation is set but not layered, and there is no high-low top-bottom order setting.

[0025] With the structure of the first embodiment of the present invention, the fibers 20 can be dispersed and filled in a space, as shown in FIG. 4, if the catalyst used is a photocatalyst, the light generated by the light sources 40 provided in the space can be irradiated to various positions of the fibers 20. Moreover, because each fiber 20 is in the form of radial divergence in space, the overlap portion between fibers is small, and the space between each other can allow air and light to pass through. Therefore, when the air flows through the photocatalyst carrier structure, the chance of collision between the photocatalyst and the air can be greatly increased, and the surface area of the photocatalyst in contact with the light can also be increased, that is, the efficiency of the sterilization equipment can be increased.

[0026] As shown in FIGS. 5-7, it is the second embodiment of the present invention. The catalyst carrier structure of the present invention comprises a ring wall 30 and a plurality of fibers 20.

[0027] The ring wall 30 takes an imaginary central axis as the central axis 10, and is set around the central axis 10.

[0028] The surface of each of the fibers 20 is coated with photocatalyst. The fibers 20 are centered on the central axis 10, and are arranged on the ring wall 30 in a radially inward radial direction along the axial direction of the central axis 10. These fibers 20 are an independent and separate fiber. These fibers 20 can be made of carbon fiber, glass fiber, or polyester. The diameter of each fiber is about 10 μm˜50 μm, and its length is 1˜200 mm.

[0029] The structure of the second embodiment of the present invention follows the same design concept of the present invention. These fibers 20 are also arranged around a central axis 10. But different from the first embodiment, in this embodiment, the central axis 10 is a virtual imaginary central axis, the fibers 20 are arranged on a ring wall 30 in a radial distribution from the outside to the inside, but the ring wall 30 is also arranged around the central axis 10 as the center. This structure can also make the fibers 20 three-dimensionally dispersed in one space, and a considerable gap can also be maintained between the fibers to increase the chance of the catalyst colliding with the air.

[0030] In the second embodiment of the present invention, if a photocatalyst is used, a light source 40 can be directly set at the position of the virtual central axis. In this way, the fibers 20 can be used to surround the light source 360 degrees, so that the light emitted by the light source 40 can be fully utilized in the reaction with the photocatalyst on the surface of the fibers 20 to improve the reaction efficiency of the sterilization equipment.
