Description

Technical Field

[0001] The utility model relates to the technical field of insoles, in particular to a 3D printed slow-release antibacterial insole. Background Art

[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis and uses adhesive materials such as powdered metal or plastic to construct objects by printing layer by layer. It is widely used in the processing field.

[0003] At the same time, insoles are often formed by hot pressing with thermoplastic molds. Existing insoles often consist of two parts: a sheet-like solid insole bottom layer and an insole surface layer attached to the insole bottom layer. They also have problems such as poor air permeability, easy breeding of bacteria, poor antibacterial performance, high foot pressure, and poor wearing comfort.

[0004] There is still a lack of better technical solutions to the problems that existing insoles in the relevant technology have poor air permeability, are easy to breed bacteria, have poor antibacterial properties, put high pressure on the feet, and are poor wearing comfort. Utility Model Content

[0005] In view of this, it is necessary to provide a 3D printed sustained-release antibacterial insole to at least solve the problems of poor air permeability, easy breeding of bacteria, poor antibacterial performance, high foot pressure and poor wearing comfort in the existing insole in the related art.

[0006] An embodiment of the present application provides a 3D printed sustained-release antibacterial insole, which includes an insole body, wherein the insole body consists of an insole bottom layer and an insole surface layer, the insole surface layer is attached to the upper surface of the insole bottom layer, the insole bottom layer is integrally formed by 3D printing, the insole bottom layer is composed of a plurality of lattice structures, the insole bottom layer is a TPU material insole bottom layer soaked in a hydrogel with sandalwood or camphorwood components, and the insole surface layer is a pure cotton material insole surface layer.

[0007] In one embodiment, the insole bottom layer includes an upper surface layer, a lattice layer, a side layer and a bottom layer, the lattice layer is arranged between the upper surface layer and the bottom layer, and the side layer is arranged on the side of the lattice layer.

[0008] In one embodiment, the insole bottom layer includes a front insole portion, a middle insole portion and a rear insole portion, and the thicknesses of the front insole portion, the middle insole portion and the rear insole portion increase from front to back.

[0009] In one embodiment, the front portion of the insole is the forefoot area, the middle portion of the insole is the medial arch area and the lateral arch area, and the rear portion of the insole is the heel area.

[0010] In one embodiment, a plurality of the lattice structures are formed with microchannels and pores.

[0011] The beneficial effects of the utility model are as follows: the application adopts 3D one-piece molding printing technology to precisely create an insole bottom layer based on a lattice structure. The lattice structure has microchannels and pores, thereby increasing the surface area so that the insole bottom layer can fully contact and absorb the hydrogel soaked with sandalwood and / or camphor wood components, optimizing the adsorption efficiency of the herbal antibacterial hydrogel, thereby achieving a more lasting and efficient sustained-release antibacterial effect, good antibacterial performance, and the microchannel and pore structure can effectively promote air circulation, improve the air permeability of the insole, reduce humidity and reduce the possibility of bacterial growth; at the same time, the lattice structure design can also reduce foot pressure, provide a more fitting and comfortable wearing experience, and is highly practical.
