[0002] A windbreaker is a functional outdoor clothing, usually used for outdoor activities under harsh weather conditions, such as mountaineering, hiking, skiing, etc. It has the functions of windproof, waterproof and breathable, and can provide protection in cold, rainy or windy environments. A windbreaker is generally made of multi-layer composite fabrics. The outer layer material is usually waterproof, and the inner layer material focuses on breathability to keep the wearer dry and comfortable.

[0003] Existing windbreakers usually sacrifice a certain degree of breathability while pursuing high waterproof performance. Although high-end windbreakers use more advanced materials, which can balance the two to a certain extent, during high-intensity exercise, sweat gas may still be difficult to quickly discharge, resulting in internal dampness. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a windbreaker with a breathable structure to solve the problems of the existing technology.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions:

[0006] A windbreaker with a breathable structure includes: a main body, a cap body arranged above the main body, a ventilation strip sewn on the inner side of the back of the main body, a break part provided on the back of the main body, a back strip covering the break part, and a connection component provided between the back strip and the main body;

[0007] By the connection component, the back strip and the main body are combined / separated to expose / cover the ventilation strip at the break part, and the interaction of the internal and external airflows of the main body is communicated / blocked through the ventilation strip.

[0008] As a further improvement, a plurality of ventilation holes are provided on the ventilation strip, and the interaction of the internal and external airflows of the main body is communicated through the ventilation holes.

[0009] As a further improvement, the ventilation strip is made of quick-drying fabric.

[0010] As a further improvement, the top of the back strip is sewn and fixed to the cap body.

[0011] As a further improvement, the connection component includes a group of first magic tapes sewn on the edge of the back strip and a group of second magic tapes sewn on the edge of the break part of the main body. Through the cooperation of the first magic tape and the second magic tape, the back strip and the main body are combined / separated.

[0012] As a further improvement, the connecting component includes a third magic tape sewn on one side of the edge of the back strip and one side of the edge of the break part of the main garment body, and a fourth magic tape sewn on the other side of the edge of the back strip and the other side of the edge of the break part of the main garment body. Through the cooperation of the third magic tape and the fourth magic tape, the back strip and the main garment body are combined / separated.

[0013] As a further improvement, the back strip is folded inwards from the middle line, and the back strip is folded through the cooperation of the third magic tape and the fourth magic tape on the back strip.

[0014] As a further improvement, the connecting component includes a fifth magic tape sewn on the upper edge of the back strip and one side of the lower edge of the break part of the main garment body, and a sixth magic tape sewn on the lower edge of the back strip and the upper edge of the break part of the main garment body. Through the cooperation of the third magic tape and the fourth magic tape, the back strip and the main garment body are combined / separated.

[0015] As a further improvement, the back strip is folded upwards from the middle part, and the back strip is folded through the cooperation of the fifth magic tape and the sixth magic tape on the back strip;

[0016] The ventilation strip, the break part, and the back strip extend above the cap body.

[0017] As a further improvement, the connecting component includes a set of first zipper tapes sewn on the edge of the back strip, a set of second zipper tapes sewn on the edge of the break part of the main garment body, and a zipper head slidably installed on the first zipper tape. The first zipper tape and the second zipper tape are combined / separated through the zipper head.

[0018] The beneficial effects of the present utility model are as follows:

[0019] Through the design of the detachable back strip, when additional ventilation is not required, the back strip covers the break part on the back of the main garment body, preventing external moisture from entering and maintaining the overall waterproof performance of the windbreaker.

[0020] When enhanced breathability is needed, the back strip can be separated from the main garment body through the connecting component, exposing the ventilation strip on the back. The ventilation strip is located on the user's back, and this part is usually the area where sweat accumulates more during high-intensity exercise. By opening the ventilation strip, the internal and external airflows can interact, promoting the discharge of moisture and heat, and achieving a better ventilation effect. The user can flexibly adjust the opening and closing state of the back strip according to the weather conditions and exercise intensity to obtain the best wearing experience in different environments.

[0021] It solves the problem that the existing windbreakers have limited breathability while pursuing high waterproof performance. Although high-end windbreakers use advanced materials to balance the waterproof and breathable performance to a certain extent, during high-intensity exercise, sweat vapor is still difficult to quickly discharge, resulting in internal dampness. By designing adjustable ventilation strips on the back of the windbreaker, users can more quickly discharge sweat vapor and moisture when they need ventilation, while maintaining the overall waterproofness of the windbreaker when it is not needed.

[0032] Embodiment 1

[0033] Refer to Figure 1-3 As shown, a windbreaker with a breathable structure includes:

[0034] A main body 1 of the garment, a cap 2 disposed above the main body 1 of the garment, a ventilation strip 3 sewn to the inner side of the back of the main body 1 of the garment, a break portion 4 provided on the back of the main body 1 of the garment, a back strip 5 covering the break portion 4, and a connection assembly provided between the back strip 5 and the main body 1 of the garment;

[0035] The back strip 5 and the main body 1 of the garment are combined / separated through the connection assembly to expose / cover the ventilation strip 3 at the break portion 4, and the interaction of the internal and external airflows of the main body 1 of the garment is connected / blocked through the ventilation strip 3.

[0036] Through the design of the detachable back strip 5, when additional ventilation is not required, the back strip 5 covers the break portion 4 on the back of the main body 1 of the garment to prevent external moisture from entering and maintain the overall waterproof performance of the windbreaker.

[0037] When enhanced breathability is required, the back strip 5 can be separated from the main body 1 of the clothing through the connecting component, exposing the ventilation strip 3 on the back. The ventilation strip 3 is located on the user's back, which is usually the area where more sweat accumulates during high-intensity exercise. By opening the ventilation strip 3, the internal and external airflows can interact, promoting the discharge of moisture and heat, and achieving a better breathability effect. Users can flexibly adjust the opening and closing state of the back strip 5 according to the weather conditions and exercise intensity, so as to obtain the best wearing experience in different environments.

[0038] It solves the problem that the breathability of existing windbreakers is limited while pursuing high waterproof performance. Although high-end windbreakers use advanced materials to balance the waterproof and breathable properties to a certain extent, during high-intensity exercise, sweat vapor is still difficult to quickly discharge, resulting in internal dampness. This solution designs an adjustable ventilation strip 3 on the back of the windbreaker, enabling users to more quickly discharge sweat vapor and moisture when they need ventilation, while maintaining the overall waterproofness of the windbreaker when not needed.

[0039] Compared with traditional windbreakers, it adds a dynamically adjustable ventilation structure. Users can adjust the opening and closing of the back strip 5 according to their own needs, and flexibly control the breathability of the windbreaker, rather than the fixed breathable material properties.

[0040] When breathability is not required, the ventilation strip 3 can be completely covered to maintain the overall waterproof performance of the windbreaker. This design effectively avoids the weakening of the waterproof effect by the ventilation structure, especially in adverse weather conditions, and can better reflect its advantages.

[0041] During high-intensity exercise, sweat vapor can be quickly discharged through the ventilation strip 3 on the back, avoiding the problem of internal dampness caused by the inability of sweat to evaporate, thereby improving the wearing comfort and exercise performance.

[0042] The combination and separation of the back strip 5 and the main body 1 of the clothing are realized through an adjustable connecting component. This structural design is simple and efficient, easy to operate, and does not significantly increase the weight and cost of the clothing. It is especially suitable for use in various outdoor activities and high-intensity exercise scenarios.

[0043] A number of ventilation holes 31 are provided on the ventilation strip 3 to connect the interaction of the internal and external airflows of the main body 1 of the clothing through the ventilation holes 31. The ventilation strip 3 is made of quick-drying fabric. The top of the back strip 5 is sewn and fixed to the cap body 2.

[0044] Setting a number of ventilation holes 31 on the ventilation strip 3 can effectively promote the exchange of air inside and outside the main body 1 of the clothing. Letting moisture and heat can be quickly discharged, among which, the aperture of the ventilation hole 31 is 1-2mm.

[0045] Too small pore diameters may limit air circulation and affect the breathability; while too large pore diameters may allow external moisture to seep in. Therefore, in this solution, the pore diameter is usually designed between 1 - 2 millimeters. This size can balance the requirements of breathability and waterproofness. Even in rainy or bad weather, the waterproof performance of the windbreaker will not be significantly reduced. At the same time, sufficient pore density can also ensure ventilation efficiency. Especially during high-intensity exercise, moisture can be quickly discharged.

[0046] The ventilation strip 3 is made of quick-drying fabric, which helps to quickly discharge sweat and evaporate moisture, preventing discomfort caused by sweat accumulation during long-term wearing. The quick-drying fabric can quickly transfer moisture from the skin surface to the external air, maintaining a dry feeling inside the clothing.

[0047] In this embodiment, the quick-drying fabric used is a polyester fiber blended fabric, which not only has excellent quick-drying performance but also has the characteristics of lightness, breathability, waterproofness and tear resistance.

[0048] In addition, the top of the back strip 5 is sewn and fixed to the cap body 2, ensuring that the back strip 5 can maintain stability during various sports and activities, and avoiding displacement or deviation of the back strip 5 due to large movement amplitude or external environmental interference (such as wind, rain). This fixing method not only enhances the protection of the ventilation strip 3 but also makes the opening and closing operation of the back strip 5 more stable.

[0049] The connection component includes a set of first magic tapes 61 sewn on the edge of the back strip 5 and a set of second magic tapes 62 sewn on the edge of the break part 4 of the main body 1. Through the cooperation of the first magic tape 61 and the second magic tape 62, the back strip 5 and the main body 1 are combined / separated.

[0050] When additional breathability is not required, the user only needs to align the first magic tape 61 on the back strip 5 with the second magic tape 62 on the edge of the break part 4 of the main body 1 and gently press. In this way, the back strip 5 will closely fit on the main body 1, completely covering the ventilation strip 3 and the break part 4. This operation is simple and fast, and the user can complete it in a short time to ensure the overall waterproofness of the windbreaker.

[0051] When enhanced breathability is needed, the user only needs to gently lift one side of the back strip 5 to separate the first magic tape 61 from the second magic tape 62. In this way, the back strip 5 will disengage from the break part 4, exposing the underlying ventilation strip 3, allowing moisture and heat inside the main body 1 to be discharged through the ventilation holes 31, realizing free air circulation. This process is also very convenient, and the user can adjust it according to needs at any time.

[0052] Users don't need complex operations or tools. They can quickly complete the merging or separation of the back strip 5 just by gently pressing or pulling. Especially during outdoor activities, users may need to quickly respond to changes in weather or exercise status, and the use of Velcro can significantly improve the convenience of operation.

[0053] Embodiment 2

[0054] Referring to Figure 4 As shown, the connecting component includes a third Velcro 63 sewn on one side of the edge of the back strip 5 and one side of the edge of the break part 4 of the main body 1, and a fourth Velcro 64 sewn on the other side of the edge of the back strip 5 and the other side of the edge of the break part 4 of the main body 1. Through the cooperation of the third Velcro 63 and the fourth Velcro 64, the back strip 5 and the main body 1 are merged / separated.

[0055] Fold the back strip 5 inward from the midline. Through the cooperation of the third Velcro 63 and the fourth Velcro 64 on the back strip 5, the back strip 5 is folded.

[0056] When additional ventilation is not needed, the user can align the third Velcro 63 and the fourth Velcro 64 on the back strip 5 with the corresponding positions on the edge of the break part 4 of the main body 1 and press them to merge. The back strip 5 lies flat on the main body 1, completely covering the ventilation strip 3. At this time, the windbreaker is in a closed state, ensuring the waterproof performance.

[0057] When enhanced ventilation is required, the user first separates the third Velcro 63 and the fourth Velcro 64 to release the back strip 5. Then, fold the back strip 5 inward from the midline so that the third Velcro 63 and the fourth Velcro 64 on both sides of the back strip 5 are attached to each other, thereby fixing the back strip 5 in the folded state. This operation fully exposes the ventilation strip 3, facilitating the air circulation inside and outside the main body 1 and discharging moisture.

[0058] By folding the back strip 5 inward from the midline and using the adhesion of the third Velcro 63 and the fourth Velcro 64 to fix the folded state, the back strip 5 can be neatly stored without affecting the appearance of the windbreaker or the user's activities due to the loose back strip 5. This design avoids the situation where the back strip 5 affects the user experience when not fixed in the ventilation mode.

[0059] Among them, the third Velcro 63 and the fourth Velcro 64 are not only used for the merging of the back strip 5 and the main body 1, but also can be fixed to each other after the back strip 5 is folded, which greatly increases the firmness of the structure. Even during strenuous exercise or in bad weather, the back strip 5 will not loosen due to vibration or wind, ensuring that the windbreaker always maintains an ideal state.

[0060] The folding and merging of the back strip 5 can be quickly completed through Velcro. Users can quickly switch between waterproof and breathable modes according to changes in weather or exercise intensity. By folding the back strip 5 inward and fixing it with Velcro, users can easily keep the ventilation strip 3 open, enhancing breathability.

[0061] This design of folding inward is very space-saving and will not affect the lightness of the windbreaker due to the excess material of the back strip 5.

[0062] Embodiment 3

[0063] Refer to Figure 5 As shown, the connection component includes a fifth Velcro 65 sewn on the upper edge of the back strip 5 and the lower edge side of the break part 4 of the main body 1, and a sixth Velcro 66 sewn on the lower edge of the back strip 5 and the upper edge of the break part 4 of the main body 1. Through the cooperation of the third Velcro 63 and the fourth Velcro 64, the back strip 5 and the main body 1 are merged / separated.

[0064] Fold the back strip 5 upward from the middle. Through the cooperation of the fifth Velcro 65 and the sixth Velcro 66 on the back strip 5, fold the back strip 5.

[0065] The ventilation strip 3, the break part 4, and the back strip 5 extend above the cap body 2.

[0066] When the user does not need additional breathability, the fifth Velcro 65 on the upper edge of the back strip 5 can be aligned and adhered to the fifth Velcro 65 on the lower edge of the break part 4 of the main body 1, and then the sixth Velcro 66 on the lower edge of the back strip 5 can be aligned and fixed to the sixth Velcro 66 on the upper edge of the break part 4 of the main body 1. In this way, the back strip 5 is closely attached to the main body 1 to form a complete protective layer, ensuring the waterproof and wind resistance performance of the clothing.

[0067] When the user needs more breathability, first separate the third and fourth Velcro 64, and then fold the back strip 5 upward from the middle. During this process, the fifth Velcro 65 and the sixth Velcro 66 on the back strip 5 cooperate to firmly fix the folded back strip 5 above the cap body 2. At this time, the back strip 5 is completely separated from the ventilation strip 3 and the break part 4, exposing the ventilation strip 3, realizing the circulation of air inside and outside the main body 1 of the clothing, and ensuring the breathable effect.

[0068] The designs of the ventilation strip 3, the break part 4, and the back strip 5 extend above the cap body 2, enabling air to flow smoothly from below to above the clothes, forming a better ventilation system. Through this design, moisture and heat can be quickly discharged, especially in a sports or high-temperature environment, helping to maintain the comfort of the wearer.

[0069] Fold the back strip 5 upwards through the middle and fix it with the fifth and sixth Velcro fasteners 66. The back strip 5 can be neatly folded above the cap body 2, avoiding the back strip 5 hanging loosely or affecting the user's range of motion. This design maintains the simplicity of the clothing appearance and prevents the folded back strip 5 from shaking or being blown open during movement.

[0070] Embodiment 4

[0071] Refer to Figure 6 As shown, the connecting component includes a set of first zipper tapes 67 sewn on the edge of the back strip 5, a set of first zipper tapes 68 sewn on the edge of the break part 4 of the main body 1 of the clothing, and a zipper head 69 slidably mounted on the first zipper tape 67. The first zipper tape 67 and the first zipper tape 68 are merged / separated by the zipper head 69.

[0072] To merge the back strip 5 with the main body 1 of the clothing, the user needs to align the first zipper tape 67 on the back strip 5 with the first zipper tape 68 at the break part 4 of the main body 1 of the clothing, insert the zipper head 69 into the starting position of the first zipper tape 68, and then pull the zipper head 69 to slide along the zipper tape to fully close the first zipper tape 67 and the first zipper tape 68 together. This operation firmly connects the back strip 5 to the main body 1 of the clothing, ensuring the waterproof and windproof performance of the entire clothing.

[0073] When increased breathability is required, the user only needs to hold the zipper head 69 and slide it in the opposite direction to when merging, open the first and the first zipper tape 68, and the back strip 5 will detach from the break part 4 of the main body 1 of the clothing, exposing the ventilation strip 3. This operation is simple and quick, and the user can easily adjust the position of the back strip 5 to achieve different wearing effects.

[0074] As a connecting component, the zipper has high firmness and durability. Even under harsh weather conditions or during strenuous exercise, the zipper can maintain a tight connection between the back strip 5 and the main body 1 of the clothing and is not easily loosened. Compared with other connection methods, the zipper can better handle high-frequency opening and closing use and can maintain excellent performance for a long time.

[0075] Using a zipper can quickly complete the merging and separation operations of the back strip 5 and the main body 1 of the clothing. The sliding operation of the zipper head 69 is simple and easy, and the user can quickly adjust the position of the back strip 5 according to the environment or needs. Whether in the waterproof mode or the breathable mode, the user can complete the switching in a short time, improving the use efficiency of the clothing.

[0076] The structure of the zipper is relatively simple and easy to maintain, and it is also very convenient to replace when there is a problem. The user can easily find a suitable replacement zipper or accessories, reducing the overall maintenance cost of the clothing. In addition, the zipper is not easily damaged and has a longer service life compared with other connection methods such as Velcro fasteners.

[0077] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
