Description

Technical Field

[0001] This invention relates to the field of down jacket technology, specifically to an outdoor down jacket with a heat-insulating and moisture-wicking circulation system design. Background Technology

[0002] In the field of outdoor sportswear, especially down jackets, there has long been a technical dilemma of balancing warmth and breathability. Traditional outdoor down jackets typically use a high-loft down filling layer combined with a windproof and waterproof outer layer to retain body heat. However, this structure leads to significant moisture buildup inside the garment when the body sweats. The condensation of sweat vapor inside the garment not only reduces wearing comfort but also causes the down insulation layer to become damp and clump together, significantly reducing its insulating performance and potentially even leading to hypothermia in extreme environments.

[0003] Currently, the solutions on the market mainly fall into two categories: one is the passive ventilation design, such as ventilation zippers under the armpits or ventilation windows on the back. This type of design requires manual operation by the user, and ventilation leads to a significant loss of heat, making intelligent adjustment impossible. The other type is the active ventilation system, which uses fans inside the garment for forced ventilation. However, this type of design has significant drawbacks: the airflow organization is unreasonable, mostly only one-way air intake or exhaust, failing to form an effective circulation; and the ventilation duct layout fails to effectively solve the heat recovery problem, with cold air directly entering the garment causing discomfort.

[0004] Therefore, there is an urgent need for a high-performance outdoor down jacket system that can intelligently sense changes in the microenvironment inside the garment, actively regulate temperature and humidity, and simultaneously recover and utilize heat to maintain the best wearing experience. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology by providing an outdoor down jacket with a heat-insulating and moisture-wicking circulation system design.

[0006] To achieve the above objectives, this invention provides an outdoor down jacket with a heat-insulating and moisture-wicking circulation system, comprising a garment body, which includes, from the outside to the inside, an outer layer, a thermal insulation layer, and an inner lining layer, and also includes a moisture-wicking circulation system integrated into the garment body; the moisture-wicking circulation system includes a micro air pump, an air intake module, an air exhaust module, a ventilation duct, and a control unit; the micro air pump is connected to the air intake module and the air exhaust module respectively through the ventilation duct to form an airflow loop; the air intake module is located at the hem or underarm area of ​​the garment, and the air intake of the air intake module is provided with a first one-way valve and an air filter; the air exhaust module is located above the shoulder or back, and the air exhaust of the air exhaust module is provided with a second one-way valve; a temperature-adjusting cavity is provided between the thermal insulation layer and the inner lining layer, and part of the ventilation duct passes through and is distributed in the temperature-adjusting cavity, and the ventilation duct located in the temperature-adjusting cavity is provided with a number of evenly distributed breathable micropores; the control unit is electrically connected to the micro air pump and is used to control its start / stop and power.

[0007] Preferably, the micro air pump is a dual-head diaphragm pump, and there are two micro air pumps distributed on both sides of the garment body; the two interfaces of the micro air pump are respectively connected to two ventilation ducts, and the two ventilation ducts are respectively connected to the air intake pipe of the air intake module and the exhaust pipe of the exhaust module through quick-connect interfaces.

[0008] Preferably, both the air intake module and the exhaust module are detachably mounted in specific parts of the garment body, and a waterproof seal is provided at the junction with the outer layer.

[0009] Preferably, the detachable method is a Velcro connection.

[0010] Preferably, the ventilation duct is a flexible silicone tube or a TPU film thermoformed tube, and the ventilation duct located in the temperature-adjusting cavity is distributed in a mesh or serpentine pattern.

[0011] Preferably, the control unit integrates a humidity sensor and a temperature sensor for real-time monitoring of humidity and temperature data within the temperature-adjusting cavity.

[0012] Preferably, the control unit has a built-in intelligent control system. When the humidity sensor detects that the humidity value exceeds a preset humidity threshold, the micro air pump is automatically started to remove moisture; when the temperature sensor detects that the temperature value exceeds a preset temperature threshold, the micro air pump is automatically started to dissipate heat.

[0013] Preferably, the control unit is also equipped with a manual switch and a mode selection key, allowing the user to manually force start and stop the moisture permeation circulation system or switch between different working modes.

[0014] Preferably, the micro air pump and the control unit are powered by a rechargeable lithium battery, which is placed in a pocket of the garment body and connected to it via a wire.

[0015] The beneficial effects of this invention are: 1. Through the collaboration of temperature and humidity sensors, the system can perceive the microenvironmental state inside the clothing in real time, realizing control of start / stop and power adjustment. 2. The bottom-in, top-out airflow direction effectively improves dehumidification efficiency. 3. The fine-tuned temperature chamber structure allows the incoming cold air to preheat by exchanging heat with the insulation layer, avoiding cold shock, while uniformly removing moisture, thus resolving the contradiction between ventilation and insulation.

[0016] 2. Both the intake and exhaust modules adopt a quick-disassembly structure, making it convenient for users to clean or replace the filter element, greatly improving the maintainability and service life of the product.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] Reference Figure 1-4 This embodiment provides an outdoor down jacket with a heat-insulating and moisture-wicking circulation system design, including a garment body 1. The garment body 1 includes, from the outside to the inside, an outer layer 2, a thermal insulation layer 3, and an inner lining layer 4. It also includes a moisture-wicking circulation system integrated into the garment body 1. The moisture-wicking circulation system includes a micro air pump 5, an air intake module, an air exhaust module, a ventilation duct 6, and a control unit. The micro air pump 5 is connected to the air intake module and the air exhaust module through the ventilation duct 6, forming an airflow loop. The air intake module is located at the hem or underarm area of ​​the garment. The air module has a first one-way valve 7 and an air filter 8 at its air inlet; the exhaust module is located above the shoulder or back, and the exhaust module has a second one-way valve 9 at its air outlet; a temperature-adjusting cavity 10 is provided between the insulation layer 3 and the inner lining layer 4, and part of the ventilation duct 6 passes through and is distributed in the temperature-adjusting cavity 10, and the ventilation duct 6 located in the temperature-adjusting cavity 10 has several evenly distributed breathable micropores 11; the control unit is electrically connected to the micro air pump 5 and is used to control its start / stop and power.

[0024] The miniature air pump 5 is a dual-head diaphragm pump. There are two miniature air pumps 5, which are distributed on both sides of the garment body 1. The two interfaces of the miniature air pump 5 are respectively connected to two ventilation pipes 6. The two ventilation pipes 6 are respectively connected to the air intake pipe of the air intake module and the exhaust pipe of the exhaust module through quick-connect interfaces.

[0025] Both the air intake module and the exhaust module are detachably installed in specific parts of the garment body 1, and a waterproof seal is provided at the joint between them and the outer layer 2.

[0026] The detachable method is a Velcro connection.

[0027] The ventilation duct 6 is a flexible silicone tube or a TPU film thermoformed tube, and the ventilation duct 6 located in the temperature-adjusting cavity 10 has a mesh or serpentine shape.

[0028] The control unit integrates a humidity sensor 12 and a temperature sensor 13 for real-time monitoring of humidity and temperature data within the temperature-adjusting cavity 10.

[0029] The control unit has a built-in intelligent control system. When the humidity sensor 12 detects that the humidity value exceeds the preset humidity threshold, it automatically starts the micro air pump 5 to remove moisture; when the temperature sensor 13 detects that the temperature value exceeds the preset temperature threshold, it automatically starts the micro air pump 5 to dissipate heat.

[0030] The control unit is also equipped with a manual switch and a mode selection key, allowing users to manually force start and stop the moisture circulation system or switch between different working modes.

[0031] The micro air pump 5 and the control unit are powered by a rechargeable lithium battery 14, which is placed in a pocket of the garment body 1 and connected to it via a wire.

[0032] Temperature sensors 13 and humidity sensors 12, distributed within the temperature-adjusting cavity 10, continuously collect environmental parameters inside the garment and transmit the data in real time to the signal processing module of the control unit. The microprocessor in the control unit compares and analyzes the received sensor data with preset thresholds. When the humidity value exceeds the preset humidity threshold, it is determined that dehumidification is required; when the temperature value exceeds the preset temperature threshold, it is determined that heat dissipation is required, and the processor generates control commands based on the analysis results.

[0033] Upon receiving a control command, the miniature dual-head diaphragm pump starts, generating negative pressure to draw in outside air from the intake module. After being filtered and purified, the outside air is delivered to the temperature-adjusting chamber 10 through ventilation duct 6. Inside the temperature-adjusting chamber 10, the ventilation duct 6 is distributed in a mesh or serpentine pattern to maximize the heat exchange area. The permeable micropores 11 on the duct walls allow the airflow to slowly seep out, fully contacting the insulation layer 3 and exchanging heat, while simultaneously carrying away water vapor evenly. After completing the heat and moisture exchange, the airflow, propelled by the miniature air pump 5, flows to the exhaust module and is discharged centrally through the second one-way valve 9 located on the shoulder and back. The entire airflow path forms a complete closed loop, achieving efficient circulation.

[0034] During system operation, sensors continuously monitor changes in environmental parameters, and the control unit adjusts the air pump power in real time based on the feedback data to achieve precise control. Once the environmental parameters return to a comfortable range, the system automatically enters standby mode.

[0035] Users can control the system's start and stop directly via a manual switch, or switch between modes using the mode selection key to meet their individual needs.
