[0018] 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.

[0019] Please see Figure 1-3 As shown, an insole according to an embodiment of the present invention includes an insole body, the insole body including a base pad 1, the base pad 1 including a lower pad layer 10 and an upper pad layer 11 bonded and fixed to the lower pad layer 10, a plurality of cavities 12 are formed between the lower pad layer 10 and the upper pad layer 11, each cavity 12 is formed with a shock-absorbing structure, the upper pad layer 11 has a receiving recess 2 formed at the arch of the shoe, the receiving recess 2 contains a deodorizing material package 20, the top surface of the base pad 1 is attached with a contact pad 3, the contact pad 3 in the attached state confines the deodorizing material package 20 in the receiving recess 2, the contact pad 3 is formed with an interactive hole 30 at the corresponding position of the receiving recess 2.

[0020] In use, several cavities 12 are formed between the upper pad 11 and the lower pad 10. Each cavity 12 is formed with a shock-absorbing structure, which improves the overall shock-absorbing performance of the insole body. The accommodating recess 2 contains a deodorizing material pack 20. When the contact pad 3 is in contact, the deodorizing material pack 20 is confined within the accommodating recess 2. The contact pad 3 is formed with an interlocking hole 30 at the corresponding position of the accommodating recess 2. The deodorizing material pack 20 contains an aromatic material (or other material with deodorizing function). The aromatic gas of the deodorizing material pack 20 enters the inside of the shoe through the interlocking hole 30 to remove odors.

[0021] The arch area is one of the areas where feet sweat the most. Placing the deodorizing material pack 20 here allows for more direct contact with sweat, effectively absorbing and decomposing odor-causing substances in the sweat, thus more effectively deodorizing. The arch area is also one of the key areas where the foot exerts force when walking. Placing the deodorizing material pack 20 here will not affect the overall comfort and support of the insole. It can also use the pressure of walking to allow the deodorizing material to better contact with the foot, enhancing the deodorizing effect. The arch area is relatively concealed, so placing the deodorizing material pack 20 here is convenient for replacement and will not affect the structure and function of other parts of the insole, which helps maintain the integrity and lifespan of the insole.

[0022] An elastic part 31 is formed at the bottom of the cavity 12. The elastic part 31 is a semi-spherical sphere and has an air guide groove 32. The air guide groove 32 gives the elastic part 31 two arc-shaped contact surfaces 33. Two installation intervals 34 are formed between the two arc-shaped contact surfaces 33 and the inner sidewall of the cavity 12. An elastic block 35 is placed inside the installation interval 34. A number of air-permeable channels 36 are distributed on the upper surface of the upper pad 11. Each air-permeable channel 36 is arranged in a linear manner on the upper surface of the upper pad 11. Each air-permeable channel 36 has a first through hole 37 at the corresponding position of each air guide groove 32. The contact pad 3 has a second through hole 38 at the corresponding position of each first through hole 37. A number of textured surfaces 4 are distributed on the upper pad 11. The contact pad 3 has hook-shaped surfaces 40 that are adapted to each textured surface 4. The contact pad 3 is attached to the upper pad 11 through the cooperation between the hook-shaped surfaces 40 and the textured surfaces 4.

[0023] In use, the contact pad 3 is attached to the upper pad layer 11 through the mating between the textured surface 4 and the hook surface 40. The mating relationship between the textured surface 4 and the hook surface 40 is the same as that of existing Velcro.

[0024] Each ventilation channel 36 is provided with a first through hole 37 at the corresponding position of each air guide channel 32, and a second through hole 38 is provided on the upper surface of the contact pad 3. The shoes that are matched with the insole of this utility model are provided with mating holes on both sides at the corresponding positions of each air guide channel 32. When the user wears the shoes, the exchange of air inside and outside the shoes is achieved through the second through hole 38, ventilation channel 36, first through hole 37, air guide channel 32 and mating holes on both sides of the shoes that are matched with the insole.

[0025] The elastic force provided by each arc-shaped contact surface 33 and the elastic block 35 provides shock absorption performance for the insole. The cavity 12 has an open structure at both ends so that the elastic block 35 can be disassembled and replaced as needed. Preferably, this utility model can be equipped with multiple sets of elastic blocks 35 with different elastic forces when sold. Users can replace the elastic blocks 35 with different elastic forces according to the usage scenario to ensure their wearing comfort. For example, when exercising, they can replace the elastic block 35 with a higher elastic force.

[0026] The surface material of the contact pad 3 is linen, and the linen is wrapped with ula grass.

[0027] When in use, the contact pad 3 is filled with treated ula grass, and then wrapped with linen to form a complete ula grass pad. The linen has good breathability.

[0028] Ula grass has the main functions of deodorizing, promoting blood circulation, relieving fatigue, improving blood microcirculation, and enhancing immunity. Ula grass, along with ginseng and mink fur, is known as one of the "Three Treasures of Northeast China." Ula grass itself has no mycorrhizae and possesses a strong inhibitory effect on fungi and bacteria. Long-term close contact with the skin can treat athlete's foot. Ula grass has excellent absorbency, absorbing moisture and automatically regulating and maintaining humidity levels, keeping the skin warm in winter and cool in summer, with effects visible on the same day of use. It also has a long-lasting, fragrant aroma and the ability to remove any unpleasant odors.

[0029] It should be noted that Ula grass material is widely used in the field of shoe insoles. For example, there is an antibacterial Ula grass shoe insole disclosed in CN220000991U, an antibacterial and moisture-proof Ula grass shoe insole disclosed in CN214283626U, an antibacterial and moisture-proof Ula grass shoe insole disclosed in CN112998351B, and a method for preparing regenerated fiber Ula grass midsole fabric disclosed in CN112841815B.

[0030] The deodorizing material pack contains 20 dehumidifying, deodorizing, or fragrance materials.

[0031] When using the product, users can place dehumidifying, deodorizing, or fragrance materials in the deodorizing material pack 20 as needed to improve the product's flexibility of use.

[0032] It should be noted that setting the deodorizing material pack 20 inside the insole is a conventional design in the prior art. For example, the Ula grass sponge insole with antibacterial and deodorizing properties disclosed in publication (announcement) number CN222303230U has a deodorizing pack inside.

[0033] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
