[0028] To make the objectives, solutions, and advantages of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0029] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that these specific details are not necessary to implement the present invention. In other embodiments, well-known structures, circuits, materials, or methods are not specifically described in order to avoid obscuring the present invention.

[0030] In the description of this utility model, the terms "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0031] The following is in conjunction with the appendix of this utility model. Figure 1-4 The embodiments of this utility model will be described in detail below.

[0032] Example 1:

[0033] This embodiment provides a wearable underwear suitable for female pets, including a main body. As a preferred embodiment, the underwear main body can be made of pure cotton material. The main body includes a back area 1 and a crotch area 2. The crotch area 2 is composed of a skin-friendly layer 10, a functional layer 20 and an outer protective layer 30 from the inside to the outside.

[0034] The functional layer 20 comprises any one or more combinations of a waterproof layer, an activated carbon functional layer, and a polymer layer. Furthermore, the waterproof layer of the functional layer 20 can be made of TPU thermoplastic polyurethane elastomer rubber film. TPU not only boasts excellent performance, effectively blocking the penetration of liquids such as urine, but also possesses good flexibility and durability, allowing it to bend and stretch with the female pet's urination movements. The skin-friendly layer 10 and the outer protective layer 30 can be made of pure cotton, resisting scratches and impacts from external objects during daily activities, working synergistically with the functional layer 20 to extend the underwear's lifespan. The activated carbon functional layer contains activated carbon powder to absorb odor gas molecules, preventing odor diffusion. The polymer layer is filled with polymer materials, which also provide waterproofing and prevent bacterial invasion; for example, polytetrafluoroethylene (PTFE) can be used as the filler for the polymer layer. It should be noted that when multiple combinations of waterproof layer, activated carbon functional layer and polymer layer are set, their arrangement order needs to meet the following requirements: when the combined structure has a waterproof layer, the waterproof layer is set on the outermost layer; when the combined structure has an activated carbon functional layer, the activated carbon functional layer is set on the innermost layer. By arranging the above order, each functional layer can better achieve its corresponding function.

[0035] Furthermore, the crotch area 2 near the skin layer 10 is provided with an absorbent layer 101, which is used to quickly absorb the urine and secretions excreted by the female pet, so as to prevent liquid leakage caused by the female pet changing its urination movements by walking or jumping, and keep the surface of the underwear dry.

[0036] Furthermore, the tail hole 3 at the junction of the back area 1 and the crotch area 2 allows the pet's tail to pass through naturally, which does not affect the normal swinging of the tail, and ensures the integrity of the underwear's coverage, preventing excrement from staining the tail. It also reduces the pet's resistance caused by the tail being restrained. At the same time, there are adjustable connecting components 60 on both sides of the back area 1. The adjustable connecting components 60 are common Velcro, snaps, elastic cords, etc., which can adjust the tightness of the underwear according to the pet's body shape. Specifically, they are set as Velcro on both sides of the crotch area 2 and the corresponding fur layer on the back area. It can be put on with just a light press, and the tightness of the fit can be flexibly adjusted.

[0037] Example 2:

[0038] This embodiment is based on the above embodiment, with reference to... Figure 2 In this embodiment, the absorbent layer 101 includes a liquid-absorbing layer 110 and an activated carbon fiber layer 120.

[0039] After a pet defecates, the absorbent layer 110 absorbs the urine and secretions excreted by the female pet, preventing leakage and avoiding prolonged skin contact with urine. This reduces the risk of skin inflammation caused by dampness, keeping the pet dry and comfortable during activity. The activated carbon fiber layer 120 quickly captures and breaks down odor molecules, preventing odors from spreading in the underwear. The absorbent layer 110 and the activated carbon fiber layer 120 work together to not only absorb excrement but also reduce the chance of bacterial growth. Bacteria in urine easily multiply in a damp environment, but the dry environment maintained by the absorbent layer and the antibacterial properties of the activated carbon fiber layer work together to inhibit bacterial growth, comprehensively protecting the pet's health.

[0040] Example 3:

[0041] To further improve the absorption efficiency, water retention, and durability of the absorbent layer 110 for pet urine, such as... Figure 3 As shown, in this embodiment, the liquid-absorbing layer 110 is composed of a four-layer composite structure, which are arranged sequentially along the liquid absorption direction as follows: a first non-woven fabric layer 1001, a flow-guiding buffer layer 1002, a polymer layer 1003, and a second non-woven fabric layer 1004.

[0042] The various layers work synergistically to form a functional gradient of "penetration → diffusion → locking → isolation," achieving highly efficient liquid absorption. Specifically: the first nonwoven fabric layer 1001 serves as the initial contact layer, utilizing its loose and porous structure to allow for rapid urine penetration, effectively preventing liquid stagnation on the surface and causing discomfort; the flow-guiding buffer layer 1002, through common fiber overlap or groove structures, disperses the liquid impact force, prevents local saturation, and buffers the liquid pressure; the polymer layer 1003 uses FlexFoam liquid material, a material made from polymers through emulsification technology, which has unique elasticity and water absorption. Its porous structure, similar to memory foam, can quickly absorb and lock in liquid, preventing backflow while maintaining its original shape even after absorbing a large amount of liquid, significantly reducing friction and allergy risks to pets' skin; the outermost second nonwoven fabric layer 1004 not only ensures that the absorbent particles in the polymer layer 1003 do not leak and cause environmental pollution, but also further improves the overall liquid isolation function, achieving a complete functional closed loop from rapid absorption to safe locking of the liquid by the absorbent layer 110.

[0043] Furthermore, the flow-guiding buffer layer 1002 is constructed from hydrophilic fiber material through a three-dimensional interweaving process, forming a honeycomb structure. The hydrophilic fiber material is flax fiber, which possesses moisture-wicking, breathable, and antibacterial properties. When urine impacts at high speed, the honeycomb structure formed by the three-dimensional interweaving of flax fibers increases the specific surface area. Upon contact with urine, the flax fibers can absorb it at an extremely rapid speed, and the dense channels formed between the fibers allow the urine to quickly and evenly diffuse in all directions, significantly improving flow-guiding efficiency and reducing the possibility of localized leakage. In addition, the three-dimensionally interwoven flax fibers support each other, preventing deformation and collapse even during repeated absorption and external pressure, thus maintaining a consistently high-efficiency flow-guiding buffer function.

[0044] Example 3:

[0045] This embodiment is based on the above embodiment. In this embodiment, the activated carbon fiber layer 120 is disposed at the bottom of the second non-woven fabric layer 1004. After the pet excretes, the activated carbon fiber layer 120 disposed at the bottom can rely on its own microporous structure to quickly absorb odors after the odorous gas passes through the second non-woven fabric layer 1004, thereby enhancing the deodorizing effect and creating a fresh environment. The liquid in the secretions of female pets may be accompanied by some impurities and microorganisms. The activated carbon fiber layer 120 can adsorb these impurities, further purify the absorbed liquid, and reduce bacterial growth.

[0046] Example 4:

[0047] To ensure that the absorbent layer of this invention can better conform to the physiological structure of female pets, such as Figure 1As shown, in this embodiment, the absorbent layer 101 is distributed longitudinally along the crotch area 2 in any of the following shapes: V-shaped, elongated, circular, or trapezoidal, with its tip pointing towards the tail hole 3. The female pet's reproductive and excretory systems are located in the crotch area, with the urethral opening relatively close to the base of the tail. The absorbent layer 101's longitudinal distribution along the crotch area in any of the following shapes, such as the V-shaped tip pointing towards the tail hole 3, matches the physiological structure of the female pet. When the female pet excretes, urine and other secretions flow out under bladder pressure and the action of the urethral sphincter. The tip of the absorbent layer 101 is located along the natural flow path of the secretions, allowing for precise capture. This close alignment with the urethral opening shortens the contact time between the liquid and the absorbent layer 101, reducing the possibility of liquid accumulation and diffusion in the crotch area, improving absorption efficiency, and enhancing the absorption effect.

[0048] Furthermore, the tip of the absorbent layer 101 extends to the front of the crotch area 2 and forms an arc-shaped transition 123 with the edge of the tail hole 3, conforming to the physiological curvature of the pet's tail root and crotch area, preventing urine leakage due to gaps caused by changes in posture after urination. At the same time, the arc-shaped transition 123 makes the contact between the absorbent layer 101 and the skin smoother, reducing friction, minimizing urine irritation to the skin, and improving the pet's comfort.

[0049] Example 5:

[0050] To further prevent urine leakage, such as Figure 1 , Figure 4 As shown, in this embodiment, the edge of the absorbent layer 101 is provided with a leak-proof strip 201.

[0051] The leak-proof strip 201 is made of latex and rubber, materials with excellent flexibility and elasticity, which allow it to fit tightly to the edge of the absorbent layer 101 and maintain a close fit as the pet moves, preventing urine leakage from the source. Its good waterproof properties also lock urine inside the absorbent layer 101. In addition, latex and rubber are durable and do not easily break or deform even after long-term contact with urine and friction pressure, extending the service life of the leak-proof strip 201.

[0052] Example 6:

[0053] This embodiment is based on the above embodiment, such as Figure 1 As shown, in this embodiment, the absorbent layer 101 is connected to the skin-like layer 10 via a detachable connection structure 40. Since the absorbent layer 101 is in direct contact with pet secretions, it is easily contaminated after use. This invention utilizes Velcro, adhesive, or other detachable connection mechanisms on the underwear, allowing for quick resolution of the problem when a female pet accidentally contaminates the absorbent layer 101. This avoids the impact of not being able to clean the pet promptly and also eliminates the need to discard the entire underwear every time the absorbent layer 101 is replaced, reducing the financial burden on pet owners.

[0054] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
