Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoe insole technology, specifically to a ula grass deodorizing and antibacterial shoe insole. Background Technology
[0002] As a functional carrier between the foot and footwear, insoles play a crucial role in cushioning and support, moisture regulation, and antibacterial and odor control, directly impacting comfort and foot health. Traditional insoles often use chemical foam materials or natural fibers, but these suffer from low moisture-wicking efficiency, easy bacterial growth, and insufficient elasticity. Furthermore, after absorbing moisture, insoles become a breeding ground for microorganisms; sweat provides nutrients, the shoe's internal environment creates a favorable environment, and microbial metabolism produces odor. Ula grass, due to its natural antibacterial properties (containing active ingredients such as quercetin and luteolin), moisture absorption and breathability, and blood-activating and health-promoting functions, has become an ideal material for novel antibacterial insoles.
[0003] To address this, related technologies have proposed insoles containing Ula grass, such as an antibacterial Ula grass insole disclosed in Chinese patent document CN221576980U and an Ula grass insole disclosed in CN222997479U; however, after the Ula grass insoles in the above patents and prior art become saturated with moisture, the release efficiency of their antibacterial components will decrease, the deodorizing and antibacterial effects of the insoles will deteriorate, and the insoles will need to be replaced frequently. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention proposes a ula grass deodorizing and antibacterial insole, which has better deodorizing and antibacterial effects and reduces the frequency of insole replacement.
[0005] The present invention provides a Ula grass deodorizing and antibacterial insole with the following technical solution: it includes an insole body and an upper surface layer disposed on top of the insole body, the two being fixedly connected; the upper surface layer includes a first guide layer, an Ula grass layer and a contact layer stacked from bottom to top; the outer periphery of the first guide layer is wrapped with a moisture-absorbing edge; the first guide layer includes multiple guide strips, the multiple guide strips are closely arranged, and at least one end of the guide strips extends into the moisture-absorbing edge.
[0006] Optionally, a second flow-guiding layer is provided between the first flow-guiding layer and the insole body, and the outer periphery of the second flow-guiding layer is wrapped with a moisture-absorbing edge; the second flow-guiding layer includes a plurality of flow-guiding strips, which are closely arranged, and at least one end of the flow-guiding strips extends into the moisture-absorbing edge; the upper surface of the second flow-guiding layer is in contact with the lower surface of the first flow-guiding layer, and the projections of each flow-guiding strip in the first flow-guiding layer and the corresponding flow-guiding strip in the second flow-guiding layer in the vertical direction have a non-zero angle.
[0007] Optionally, the guide strips on the forefoot portion of the first guide layer are radially distributed, and the outer ends of the guide strips extend into the moisture-absorbing edge.
[0008] Optionally, the contact layer is a nonwoven fabric blended with activated carbon fibers.
[0009] Optionally, the insole body is detachably and fixedly connected to the upper surface layer.
[0010] Optionally, the forefoot portion of the contact layer is provided with multiple conical protrusions, which are filled with concentrated urla grass granules.
[0011] Optionally, the contact layer and the Ula grass layer can be detachably fixed together.
[0012] The beneficial effects of this utility model are as follows: This utility model provides an anti-odor and antibacterial insole made of Ula grass. By setting closely arranged guide strips below the Ula grass layer to construct a guide net, and setting a moisture-absorbing edge on the outer periphery of the first guide layer, the moisture in the Ula grass is guided to the moisture-absorbing edge during use, thereby reducing the humidity of the Ula grass layer, improving the release efficiency of its antibacterial components, significantly inhibiting bacterial growth, optimizing the anti-odor and antibacterial effect, extending the service life of the insole, and reducing the frequency of insole replacement.
[0013] Furthermore, by arranging the guide strips on the forefoot in a radial pattern, the speed at which sweat flows from the forefoot to the moisture-absorbing edge is accelerated. In addition, by setting a first guide layer and a second guide layer, and ensuring that the vertical projections of each guide strip in the first guide layer and the corresponding guide strip in the second guide layer have a non-zero angle, a three-dimensional guide network is constructed, which further accelerates the flow of sweat, further reduces the humidity of the Ula grass, and optimizes the deodorizing and antibacterial effects.
[0014] Furthermore, the contact layer is made of activated carbon fiber blended non-woven fabric, and the forefoot portion of the contact layer has conical protrusions filled with concentrated urla grass particles. During use, the activated carbon adsorbs odor molecules such as isovaleric acid. The conical protrusions massage the sole of the foot and slowly release urla grass particles outward, specifically enhancing the antibacterial concentration in the high-bacterial-load area of the forefoot. In addition, the modular insole allows for detachable and fixed connections between the insole body and the upper surface layer, as well as between the contact layer and the urla grass layer. This allows for the replacement of corresponding modules based on usage when changing the insole, solving the resource waste caused by the complete disposal of traditional insoles.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides an odor-resistant and antibacterial insole made of Ula grass, comprising an insole body 100 and an upper surface layer disposed above the insole body 100, the two being fixedly connected, and the insole body 100 and the upper surface layer being detachably fixedly connected; the upper surface layer comprises a first guide layer 200, an Ula grass layer 300, and a contact layer 400 stacked from bottom to top; the outer periphery of the first guide layer 200 is wrapped with a moisture-absorbing edge 220; the first guide layer 200 includes a plurality of guide strips 210, the plurality of guide strips 210 being closely arranged, and at least one end of the guide strips 210 extending into the moisture-absorbing edge 220. A second guide layer 500 is disposed below the first guide layer 200, the outer periphery of the second guide layer 500 being provided with a moisture-absorbing edge 220, the second guide layer 500 including a plurality of guide strips 210, the plurality of guide strips 210 being closely arranged, and at least one end of the guide strips 210 extending into the moisture-absorbing edge 220. The upper surface of the second flow guiding layer 500 and the lower surface of the first flow guiding layer 200, and the vertical projections of each flow guiding strip 210 in the first flow guiding layer 200 and the corresponding flow guiding strip 210 in the second flow guiding layer 500, have a non-zero included angle. Figure 4 The included angle shown is a right angle.
[0024] During use, the guide strips 210 of the first guide layer 200 and the second guide layer 500 form a three-dimensional guide network, guiding the moisture in the Ula grass to the moisture-absorbing edging 220. The intersection of the upper and lower guide strips 210 forms a liquid transmission node, accelerating the flow of sweat. Moisture-absorbing edging 220 is provided on the outer periphery of both the first guide layer 200 and the second guide layer 500. During use, the guide strips 210 guide the liquid to the moisture-absorbing edging 220. When the guided liquid forms a complete pathway from the Ula grass layer 300 to the moisture-absorbing edging 220, it will continuously guide the liquid in the Ula grass to the moisture-absorbing edging 220, thereby reducing the humidity of the Ula grass layer 300, improving the release efficiency of its antibacterial components, significantly inhibiting bacterial growth, optimizing the deodorizing and antibacterial effect, extending the service life of the insole, and reducing the frequency of insole replacement.
[0025] Example 2
[0026] Unlike Example 1, the guide strips 210 on the forefoot portion of the first guide layer 200 are radially distributed. By making the guide strips 210 on the forefoot portion radially distributed, the speed at which sweat flows from the forefoot to the moisture-absorbing edge 220 is accelerated, further reducing the humidity of the Ula grass and optimizing the deodorizing and antibacterial effect.
[0027] Example 3
[0028] Unlike Examples 1 and 2, the contact layer 400 is made of activated carbon fiber blended nonwoven fabric. The forefoot portion of the contact layer 400 has multiple conical protrusions filled with concentrated urla grass granules. During use, the activated carbon adsorbs odor molecules such as isovaleric acid. The conical protrusions massage the sole of the foot and slowly release urla grass granules outwards, specifically enhancing the antibacterial concentration in the high-bacterial-load area of the forefoot. The insole body 100 is detachably fixed to the upper surface layer. The contact layer 400 is detachably fixed to the urla grass layer 300. By modularizing the insole, after a period of use, the corresponding modules can be replaced according to specific usage conditions, solving the resource waste problem caused by the complete disposal of traditional insoles. The detachable fixed connection can be a snap-on connection or a Velcro connection (both the rough and hook sides).
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
