Description

I. Technical Field

[0001] The present invention relates to the technical field of footwear, and particularly to a shoe with a unique odor release function. Specifically, it realizes odor release based on sole friction and air flow drive, and is a shoe with adjustable odor concentration. II. Background Art

[0002] Currently, the research and development focus of footwear products mostly lies in aspects such as comfort, aesthetics, and protection, with less investment in the development of odor release functions. However, in many scenarios, there is a significant demand for shoes with odor release functions. For example, in the home environment, people expect to eliminate foot odor through the odor emitted by shoes and keep the indoor air fresh; in outdoor scenarios, some people hope to use the shoe odor to drive away specific animals to ensure their own safety; there are also people who like to make the shoes emit pleasant aromas in specific environments to create a comfortable atmosphere.

[0003] Most existing odor release products use the method of externally spraying perfume or placing aromatherapy. This method has many drawbacks. It requires frequent operation during use, which is extremely inconvenient; moreover, the odor release is uneven, and the odor may be strong in some places while very weak in other places; the odor duration is short and it is difficult to meet the long-term use requirements. Therefore, developing a shoe that can skillfully integrate the odor release function into the shoe body structure and achieve stable and controllable odor release by means of sole friction and walking air flow is of great significance. It can not only bring a new wearing experience to users, but also fill the market gap. III. Summary of the Invention

[0004] (I) Invention Objectives

[0005] The present invention aims to design an odor release shoe based on sole friction and air flow drive, and achieve an efficient odor release function through innovative structural and material applications. During daily wear, the shoe can continuously and stably emit odors. At the same time, users can easily adjust the odor concentration according to actual needs, and it will not have any adverse effects on wearing comfort.

[0006] (II) Technical Solutions

[0007] 1. Upper Design: Select a special porous textile fabric, specifically a chemically modified polyester fiber material. Its surface has undergone chemical grafting treatment to form functional groups that are affinity for microcapsules. Lemon extract is encapsulated in the microcapsules, and the shell material is biodegradable polylactic acid (PLA). After the microcapsules are evenly sprayed on the fabric surface, they are firmly bonded to the fiber material by means of hot pressing technology. During the wearing process, the friction and temperature changes generated by human activities will cause the microcapsules to gradually rupture, thereby slowly releasing the lemon odor.

[0008] 2. Sole Structure: The sole is made of rubber material, in which lemon essential oil powder accounting for 10% (5% - 15% is applicable) of the rubber mass is evenly mixed. This essential oil powder is prepared by spray drying process and evenly added to the rubber raw material during the mixing stage. In this way, when the sole rubs against the ground, the pressure will promote the slow release of the essential oil. At the same time, ventilation holes and internal diffusion cavities are provided at the connection between the upper and the sole. The air flow generated during walking will enter the diffusion cavity through the ventilation holes, thereby enhancing the spread range of the smell.

[0009] 3. Odor Adjustment Device: A replaceable odor adjustment box is designed at the tongue part of the shoe. This adjustment box is a detachable box containing lemon-scented gels with different concentrations, and is fixed on the tongue of the shoe by magnetic attraction or slotting methods. Users can choose the gel module with the appropriate concentration for replacement according to the actual usage scenarios, such as the activity level of the cat, the usage environment, etc., to achieve flexible adjustment of the odor concentration.

[0010] 4. Overall Material and Structural Characteristics: The materials used in the overall structure are environmentally friendly and non-toxic, and the odor source is natural, which is suitable for long-term daily wear. The upper and the sole are bonded with a high-molecular environmentally friendly glue to ensure the smoothness of the odor diffusion channel. And during the sewing process of the upper, the interface positions for connecting with the odor adjustment box and the ventilation holes are reserved.

[0011] (III) Beneficial Effects

[0012] 1. Stable Odor Release: Through the slow release of lemon odor by the microcapsules on the upper and the friction release on the sole, combined with the driving of the walking air flow, stable and continuous odor release is achieved, overcoming the problems of uneven and non-persistent odor release in the traditional way.

[0013] 2. Convenient Adjustment: Users can independently replace the lemon gel in the odor adjustment box at the tongue of the shoe to easily adjust the odor concentration and meet the usage requirements in different scenarios.

[0014] 3. Environmentally Friendly and Safe: The materials used are environmentally friendly and non-toxic, and the odor comes from natural lemon extracts and lemon essential oil, which are harmless to the human body and the environment and are suitable for long-term wearing.

[0015] 4. Practical Function: In addition to meeting people's needs for shoes with special odors, it can also solve the problem of foot odor to a certain extent, and play a role in driving specific animals in specific scenarios, enhancing the practicality of the shoes. IV. Description of the Drawings

[0016] (I) Figure 1 : Schematic Diagram of the Overall Structure of the Shoe

[0017] 1. Ventilation & Scent Channel: Located between the upper and the sole, it has a honeycomb structure of tiny ventilation holes or ducts. When walking, air flows through this channel to export the lemon scent from inside the shoe, connecting the scent diffusion cavity with the outside, which greatly enhances the diffusion efficiency of the lemon scent. Its working principle is to utilize the airflow generated during walking to push the scent to flow through the channel for efficient dispersion.

[0018] 2. Area of lemon essential oil particles in the sole: That is, the part of the sole embedded with lemon essential oil powder. When the sole rubs against the ground, pressure will prompt the slow release of the essential oil, which is a passive dispersion method. Cooperating with the ventilation & scent channel, it can effectively increase the scent concentration. When designing, the normal service life of the sole was fully considered to ensure that the scent release would not have a negative impact on it.

[0019] 3. Adjustable scent control box (located at the tongue of the shoe): It is a replaceable box containing lemon scent gels with different concentrations. Fixed on the tongue of the shoe by magnetic attraction or slots, users can select the scent concentration according to the actual environment, just as convenient as replacing a scented sachet box. This design belongs to the active control module, enabling users to adjust the scent effect more freely.

[0021] 1. Linear wavy structure: It is the fiber layer of the textile fabric, providing an attachment basis for the microcapsules.

[0022] 2. Microcapsules (No. 10): The dotted line with dots above represents the embedded microcapsules, which contain lemon scent inside. During wearing, with the friction and temperature changes generated by human activities, the microcapsules gradually break and release the lemon scent.

[0023] 3. Fabric No. 1: The overall fabric uses modified polyester fiber material, which has been chemically grafted and has functional groups that are affinity for microcapsules.

[0024] 4. Bottom support layer: It plays a role in supporting the fabric and microcapsules to ensure the stability of the entire structure.

[0025] (Three) Figure 3 : Schematic diagram of the distribution of lemon essential oil powder in the sole

[0026] 1. Sole (rubber layer, No. 2): As the support structure of the shoe, it provides stable support for walking.

[0027] 2. Lemon essential oil particles (No. 12): Powder particles embedded in the rubber. When the sole rubs against the ground, under the action of pressure, they slowly release lemon essential oil to achieve the scent dispersion function.

[0028] (Four) Figure 4 : Schematic diagram of the odor ventilation hole structure between the upper and the sole

[0029] 1. Upper material (No. 2): Contains a microcapsule fiber layer, which is used to release the lemon smell and is one of the sources of the odor.

[0030] 2. Ventilation holes (No. 4): used for air flow. When walking, the air in the shoe flows through the ventilation holes, bringing out the lemon smell, which is the key channel for the spread of odor. The diameter of the ventilation holes is 0.5mm-1.5mm, connected to the diffusion cavity inside the upper, ensuring the smooth flow of air and odor.

[0031] 3. Diffusion chamber (No. 15): It has a honeycomb structure, which can effectively enhance the odor diffusion effect. When the odorous air enters the diffusion chamber, the honeycomb structure increases the contact area between the odor and the air, allowing the odor to diffuse more evenly and widely into the external environment.

[0032] 4. Sole: It is not only a supporting structure, but also contains an odor release device (lemon essential oil powder), which works together with the upper to achieve the overall odor release function.

[0035] 2. Smell adjustment box (No. 14): A detachable box for replacing the smell module. It is connected to the tongue of the shoe through a magnetic structure, which is easy to disassemble and replace. Users can choose different concentrations of lemon gel according to actual needs.

[0036] 3. Lemon gel (No. 16): The core odor source in the replaceable module, with different concentrations to choose from. Users can adjust the concentration of shoe odor by replacing different concentrations of lemon gel to adapt to different usage scenarios. V. Specific implementation methods

[0037] (I) Upper production

[0038] Modified polyester fiber material is used to make the upper. First, the surface is chemically grafted to make it have functional groups that are compatible with microcapsules. Microcapsules wrapped with lemon extract and with a shell of polylactic acid (PLA) are evenly sprayed on the surface of the fabric. Then, hot pressing technology is used to tightly combine the microcapsules with the fiber material under a certain temperature and pressure to ensure that the microcapsules can stably release the lemon smell during subsequent wearing.

[0039] (2) Sole production

[0040] The sole is made of rubber material. After the lemon essential oil powder, which accounts for 10% (adjustable between 5% - 15%) of the rubber mass, is prepared by spray drying process, it is evenly added to the rubber raw material during the mixing stage. After uniform mixing, the sole is made by molding with a mold. At the connection between the sole and the upper, several micro ventilation holes with a diameter of 0.5mm - 1.5mm are opened to form an odor diffusion channel, ensuring that the air inside the shoe can flow smoothly during foot movement and release the odor to the outside.

[0041] (III) Installation of the odor adjustment device

[0042] A detachable odor adjustment box is embedded inside the tongue of the shoe, and replaceable lemon gel blocks are placed inside the box. The gel blocks are divided into three concentrations: high, medium, and low, and users can choose to replace them according to actual needs. The odor adjustment box is installed on the tongue of the shoe through a magnetic attraction structure, which is convenient for disassembly and fixation. Users can complete the replacement of the gel block by simply sucking and pulling gently.

[0043] (IV) Overall assembly

[0044] The upper and the sole are bonded with a high molecular environmental protection glue. During the bonding process, it is necessary to ensure the smoothness of the odor diffusion channel and avoid blocking the ventilation holes with glue. During the sewing process of the upper, the interface positions connected to the odor adjustment box and the ventilation holes are reserved in advance to ensure the accurate installation of each component.

[0045] Through the above manufacturing and assembly process, the shoes of the present invention can continuously release effective cat - repelling odor for more than 3 months in a normal wearing environment through the slow release of microcapsules on the upper, the release by sole friction, and the driving of walking airflow, and have the advantages of obvious cat - repelling effect, long service life, environmental protection and safety.
