The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1 to 4 In this embodiment of the utility model, a down jacket that prevents down leakage includes: a jacket body 1, which serves as the main structure of the entire down jacket, providing a carrying space for the internal down filling and various layers, playing a role in wrapping and protecting, maintaining the overall shape of the jacket, and making it convenient for the user to wear. The jacket body 1 is composed of multiple sets of fabric layers 2 and multiple sets of inner lining layers 3. The fabric layers 2 are the outer material of the jacket and play a certain protective role, while the inner lining layers 3 are close to the human body.

[0021] A connecting mechanism 4 is provided at the edge of the fabric layer 2 and the inner lining layer 3, which serves to connect the fabric layer 2 and multiple sets of inner lining layers 3. Down 5 is filled between the fabric layer 2 and the inner lining layer 3. It is the key material for the jacket to achieve its warmth function. Its fluffy properties lock in air and reduce the loss of body heat.

[0022] The fabric layer 2 has a nano waterproof and breathable membrane layer 6 with extremely small pores, which can prevent down from escaping from the fabric surface while allowing water vapor molecules to pass through. The inner lining layer 3 has a honeycomb structure 7 on its inner surface, which can restrict down movement, prevent excessive gathering or escaping, and ensure normal air circulation inside the jacket.

[0023] Reference Figure 1 A sleeve 8 is fixedly connected to one side of the jacket body 1, providing coverage and protection for the arm. An elastic cuff 9 is fixedly connected to one end of the sleeve 8, which can adaptively adjust the tightness according to the size of the wrist and fit the wrist closely. There are two sets of both the sleeve 8 and the elastic cuff 9, and the two sets of sleeve 8 are symmetrically arranged on both sides of the jacket body 1.

[0024] The jacket body 1 is fixedly connected to the top of the jacket collar 10, which keeps the neck warm and prevents heat loss from the neck. The lower front of the jacket body 1 has a pocket 11, which is convenient for users to put small items such as keys and mobile phones, increasing the practicality and functionality of the jacket.

[0025] Reference Figure 1 , Figure 2 and Figure 4 The connecting mechanism 4 includes an I-shaped connecting strip 401 and a waterproof rubber ring 402. The I-shaped connecting strip 401 is located at the edge of each pair of multiple fabric layers 2 and multiple inner lining layers 3. The waterproof rubber ring 402 is fixedly connected to one end of the outer side of the I-shaped connecting strip 401.

[0026] A connecting fabric ring 403 and a sewing thread 404 are used. The connecting fabric ring 403 is located at the other end of the outer side of the I-shaped connecting strip 401, and the sewing thread 404 is located in the middle of the connecting fabric ring 403 and is sewn to the fabric layer 2 and multiple sets of inner lining layers 3. Two sets of waterproof rubber rings 402, connecting fabric rings 403, and sewing threads 404 are provided. The two sets of waterproof rubber rings 402 are symmetrically arranged at both ends of the outer side of the I-shaped connecting strip 401. The edges of each pair of fabric layers 2 and inner lining layers 3 are placed in the grooves on the side of the I-shaped connecting strip 401. The groove design of the I-shaped connecting strip 401 provides precise positioning space for the edges of the fabric layer 2 and inner lining layers 3. The connecting fabric ring 403 is placed on the outer side of the I-shaped connecting strip 401 corresponding to the edges of the fabric layer 2 and inner lining layers 3. The sewing thread 404 sews together the fabric layer 2, the inner lining layer 3, the connecting loop 403, and the I-beam connecting strip 401. The sewing thread 404 passes through these components and tightly binds them together. This sewing method not only further fixes the edges of the fabric layer 2 and the inner lining layer 3, but also firmly connects the connecting loop 403 and the I-beam connecting strip 401 to them. The sewn structure can effectively prevent down from coming out from the edges. The waterproof rubber ring 402 is placed on the I-beam connecting strip 401 and heat-sealed. The waterproof rubber ring 402 has good waterproof and sealing performance. The heat-sealing operation makes it fit tightly on the I-beam connecting strip 401. When the jacket is exposed to external moisture, the waterproof rubber ring 402 can prevent moisture from entering the jacket through the edge joint.

[0027] The working principle of this utility model is as follows: The edges of every two sets of fabric layers 2 and inner lining layers 3 are placed within the grooves on the side of the I-shaped connecting strip 401. The groove design of the I-shaped connecting strip 401 provides precise positioning space for the edges of the fabric layers 2 and inner lining layers 3, allowing them to be neatly and tightly arranged together, laying the foundation for subsequent connection operations. This embedding method initially restricts the relative movement of the fabric layers 2 and inner lining layers 3, reducing the possibility of down feathers escaping from the edge gaps. The connecting cloth ring 403 is placed on the outside of the I-shaped connecting strip 401 corresponding to the edges of the fabric layers 2 and inner lining layers 3, serving as a transition. In addition to strengthening the connection, it increases the strength and stability of the connection area, making subsequent sewing operations more secure. Simultaneously, the connecting loop 403 can also distribute the pressure of the sewing thread 404 on the fabric layer 2 and the inner lining layer 3, preventing fabric damage due to sewing. The fabric layer 2, inner lining layer 3, connecting loop 403, and I-beam connecting strip 401 are sewn together by the sewing thread 404. The sewing thread 404 passes through these components, tightly binding them together. This sewing method not only further secures the edges of the fabric layer 2 and inner lining layer 3 but also firmly connects the connecting loop 403 and I-beam connecting strip 401 to them. The combined structure effectively prevents down from escaping from the edges, while ensuring the durability of the jacket body 1 during daily wear and use. A waterproof rubber ring 402 is placed on the I-beam connector 401 and heat-sealed. The waterproof rubber ring 402 has excellent waterproof and sealing properties; the heat-sealing operation ensures it adheres tightly to the I-beam connector 401. When the jacket is exposed to external moisture, the waterproof rubber ring 402 prevents moisture from entering the jacket through the edge joint, protecting the down from moisture and further enhancing the sealing of the joint, preventing down from escaping from the edges. The nano-waterproof and breathable membrane layer 6 has extremely small pores, which can block… While preventing down from escaping from the fabric surface, it allows water vapor molecules to pass through. This means that while ensuring down-proof performance, sweat vapor generated inside the jacket can be smoothly discharged, keeping the wearer dry and comfortable. At the same time, it prevents external moisture from entering the jacket and affecting the performance and warmth of the down. The honeycomb structure 7 has regular pores of moderate size. These pores can restrict the movement of down, preventing excessive down accumulation or escaping, while also ensuring normal air circulation inside the jacket. This structure helps improve the jacket's warmth performance, allowing heat to be evenly distributed inside the jacket, and also increases the strength and stability of the inner lining.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
