[0002] This disclosure claims priority to Chinese Patent Application No. CN2024217278545, filed on July 19, 2024, entitled "A Temperature-Regulating Bag", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of wearable bag technology, and more particularly to a temperature-regulating bag. Background Technology

[0004] [Corrected according to Rule 91, July 17, 2025] In recent years, with the increasing severity of global warming and extreme summer heat, the market demand for portable temperature control devices has been expanding. Besides general consumers, commercial hot environments (such as construction sites, warehouses, and factories) and specific industries (such as outdoor work, outdoor sports, and express delivery) have become major application areas. Current portable temperature control devices are mainly fan-operated clothing based on traditional fans, relying on increasing the number or power of fans to increase airflow and provide a greater cooling effect. However, this places higher demands on fan capacity and battery capacity. Due to current technological limitations, increasing airflow has limited effect on improving cooling and has corresponding drawbacks: such as increased battery weight, increased user burden, noise from high-powered fans, environmental and cost issues, etc.

[0005] Furthermore, the fan-operated clothing expands due to the wind force during use and cannot effectively connect to work tools (work belts and tool bags, etc.) worn around the waist, causing inconvenience and affecting work efficiency to some extent.

[0006] Fan-cooled clothing is greatly affected by ambient temperature, and its effectiveness is limited or even nonexistent in high-temperature environments. For example, in the sweltering summer, relying solely on the fan-cooled clothing to blow air often fails to effectively reduce the perceived temperature. In fact, the introduction of hot airflow may even make users feel more uncomfortable, and the added weight of portable temperature-regulating devices can also cause fatigue.

[0007] The design of the air inlet, air duct, and air blowing point of a portable temperature control device can all affect its temperature control effect. For example, if the air inlet of a portable temperature control device is poorly positioned or easily blocked, or if the air duct is unclear, airflow will be obstructed, thus affecting the cooling effect.

[0008] Therefore, in order to overcome the shortcomings of traditional fan-made clothing, such as limited cooling effect and unreasonable design, it is of great importance to provide a more effective and portable local cooling solution.

[0009] Public content

[0010] In view of this, embodiments of the present disclosure provide a temperature-regulating bag to eliminate or improve one or more defects present in the prior art.

[0011] A temperature-regulating bag has a main body for wearing on the human body. The main body includes a fan mounting part, a temperature-regulating component mounting part, a cavity air duct, and an air outlet. The fan mounting part is located at the bottom of the main body, the cavity air duct is located inside the main body and connects the fan mounting part and the air outlet, and the temperature-regulating component mounting part is located inside the cavity air duct and is used to change the temperature of the airflow passing through the cavity air duct after the temperature-regulating component is installed. The cavity air duct includes a main air duct, which is a straight channel when worn.

[0012] In some embodiments, the bag body has a Y-shaped structure, including two shoulder bodies located at the branching parts and a back body located at the main body, thereby forming a backpack shape that can be carried on the back.

[0013] The cavity air duct also includes a branch air duct, which is located on the shoulder body, while the main air duct is located on the back body, and the branch air duct is connected to the main air duct.

[0014] In some embodiments, the air outlet includes at least one air outlet, and the branch duct is provided with a support member at the air outlet. The height of the support member is greater than the size of the air outlet in the thickness direction of the shoulder body, so as to support the air outlet to always remain open in the thickness direction of the shoulder body.

[0015] In some embodiments, the air outlet portion includes a fixing member disposed at each of the air outlet portions, the fixing member being embedded in the opening outline position of the air outlet for maintaining the air outlet in a fixed shape.

[0016] In some embodiments, the aspect ratio of the main air duct of the bag body is 2:1 to 3:1.

[0017] In some embodiments, at least one temperature regulating element mounting portion is provided; in the case of multiple portions, the temperature regulating element mounting portions are arranged along the length or width direction of the main air duct.

[0018] In some embodiments, the temperature-regulating bag further includes at least one energy storage component mounting portion for mounting an energy storage component, the energy storage component mounting portion being located at the bottom of the shoulder body or the back body of the bag body;

[0019] When the energy storage component mounting part is located on the shoulder of the bag body, a wiring channel for embedding fan wires is provided inside the bag body.

[0020] In some embodiments, the shoulder body and / or back body of the bag body are provided with a connection structure for connecting to a waist tool bag or work belt.

[0021] In some embodiments, the shoulder body of the bag body is provided with a plurality of straps for securing the seat belt shoulder strap.

[0022] In some embodiments, the air outlet is disposed on the branch air duct located on the shoulder body and above the main air duct.

[0023] In some embodiments, several of the air outlets are arranged on opposite sides of the two shoulder bodies to face the user’s neck or cheek, with an air outlet angle of 0-90°.

[0024] In some embodiments, the angle between the fan mounting portion and the human-facing contact surface of the bag body is 45-90°.

[0025] In some embodiments, the bag body includes an outer layer, an insulation layer, a first sealing layer, a second sealing layer, a cushioning layer, and a breathable layer, wherein the cavity between the first sealing layer and the second sealing layer forms the cavity air duct.

[0026] In some embodiments, the second sealing layer has a plurality of vents, and the buffer layer includes a breathable buffer member, so that the airflow in the cavity air duct can also penetrate to the wearer's body surface through the vents, the buffer member and the breathable layer.

[0027] This disclosed temperature-regulating bag provides a portable solution for adjusting airflow temperature, suitable for use in situations requiring the maintenance of a comfortable temperature in specific environments. The bag features improvements in air intake design, airflow duct design, and airflow distribution, enabling it to provide comfortable airflow temperature regulation while worn. These design improvements also contribute to the bag's efficient and stable airflow. The fan, mounted at the bottom of the bag, more effectively draws in air from below and pushes it to other parts of the bag without interfering with airflow from other items carried by the user. The straight-through design of the main airflow duct minimizes resistance within the duct, allowing the fan-push air to reach the target area more effectively, thereby improving airflow efficiency, providing maximum airflow for temperature regulation, and enhancing the temperature control effect.

[0044] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0045] In the following description, embodiments of the present disclosure will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0046] This disclosure aims to provide a portable solution for regulating airflow temperature, suitable for use in situations requiring the maintenance of a comfortable temperature in specific environments. The temperature-regulating bag features improvements in its air intake design, airflow duct design, and airflow outlet design, enabling it to provide comfortable airflow temperature regulation while worn. These design improvements also contribute to the bag's efficient and stable airflow, offering convenience for various usage scenarios.

[0047] As shown in Figures 1-3, the temperature-regulating bag has a main body for wearing on the human body, and the main body includes: a fan mounting part 13, a temperature-regulating component mounting part 14, a cavity air duct 15, and an air outlet 16, etc.

[0048] The fan mounting part 13 is located at the bottom of the bag body and is used to fix or detachably mount the fan.

[0049] The cavity air duct 15 is located inside the bag body and connects the fan mounting part 13 and the air outlet 16. It is used as an air supply channel. The air supply channel should be designed to be smooth or straight enough to avoid air pressure loss and ensure sufficient air pressure.

[0050] The temperature regulating component mounting part 14 is located inside the cavity air duct 15. After the temperature regulating component is installed, it is used to change the temperature of the airflow passing through the cavity air duct 15. It can be understood that the temperature regulating component mentioned here refers to a cold source that needs to be used for cooling or a heat source that needs to be provided for heating. The cold source can be an ice pack, a frozen water bottle, or a Peltier device, etc., and the heat source can be an electric heater, a hand warmer, or a thermoelectric device, etc.

[0051] The cavity air duct 15 includes a main air duct 151, which is a straight channel when worn, ensuring that the airflow can flow smoothly to the air outlet 16. The air outlet 16 is located on one side or top of the bag body and is used to release the temperature-controlled airflow.

[0052] In the above embodiment, the temperature-regulating bag can be worn on the user's body. The fan, mounted at the bottom of the bag, can more effectively draw air in from below and push it to other parts of the bag. This arrangement helps create a good airflow path, making air circulation throughout the system smoother. Mounting the fan at the bottom of the temperature-regulating bag increases its stability and balance. The bottom of the bag can be one end, providing sufficient support to prevent vibration or swaying caused by fan operation. Mounting the fan at the bottom of the bag will not affect airflow when the user is carrying other items, such as tool bags, production materials, or tools.

[0053] In the above embodiments, the main air duct 151 being a straight channel (or straight-through design) offers numerous advantages. The straight-through design minimizes resistance within the duct because air does not need to change direction at multiple bends or branches. This ensures that the airflow and speed blown by the fan are not reduced due to resistance losses, thereby improving overall fan efficiency and performance, reducing energy consumption, and extending equipment lifespan. The straight-through design ensures that airflow within the duct is linear, avoiding uneven or turbulent flow caused by bends or branches. Because the straight-through design reduces air resistance and uneven flow within the duct, it also reduces noise generation. The straight-through design allows the air pushed by the fan to reach the target area more effectively, thereby improving overall airflow efficiency. The straight-through design makes the duct easier to clean and less prone to dirt accumulation and bacterial growth.

[0054] In some embodiments, as shown in Figures 1-3, the bag body has a Y-shaped structure, including two shoulder bodies 12 located at the branch points and a back body 11 located at the main body, thus forming a backpack shape that can be carried. The Y-shaped bag body, divided into shoulder and back bodies 11, can better conform to the curves of the human shoulder and back, providing a more comfortable wearing experience. This design takes ergonomics into account, making it easier to carry and allowing the bag to fit more snugly and stably during use. The Y-shaped structure design is not only suitable for everyday wear, but can also function in environments requiring specific temperature control, such as outdoor sports, medical care, or special work environments.

[0055] The cavity air duct 15 also includes a branch air duct 152, which is located on the shoulder body 12, while the main air duct is located on the back body 11. The branch air duct 152 is connected to the main air duct 151. This layout ensures that the temperature-controlled airflow can flow smoothly from the branch air duct 152 to the main air duct 151, and is finally released through the air outlet 16, ensuring efficient and uniform air circulation.

[0056] In some embodiments, the air outlet 16 includes at least one air outlet 161, and the branch air duct 152 is provided with a support member 162 at the air outlet 161. The height of the support member 162 is greater than the dimension of the air outlet 161 in the thickness direction of the shoulder body 12, and is used to support the air outlet 161 to always remain open in the thickness direction of the shoulder body 12. As shown in Figure 4 or Figure 8, the support member 162 can be a semi-circular or other shape of support tube with an open structure on one side. Its arc surface, vertical surface, or inclined surface is close to one side of the bag body to support the air outlet 161, ensuring that it remains open even when the shoulder body is bent. It can also ensure that in specific usage environments, such as movement, travel, or various operations, the air outlet 161 can always maintain a relatively stable air outlet angle and unobstructed flow, thereby ensuring the effect of air circulation and the stability of temperature regulation.

[0057] In addition, a fixing member 163 may be provided at the air outlet 161. The fixing member 163 is embedded in the opening contour of the air outlet 161 to keep the air outlet 161 in a fixed shape. The fixing member 163 can be made of materials such as metal or plastic, has a certain supporting strength, and is fixedly embedded in the contour of the air outlet 161 to prevent the air outlet 161 from closing, ensuring that the air outlet 161 is always in the open state.

[0058] In the above embodiments, the support member 162 is mainly used to prevent the branch air duct 152 of the temperature regulating bag from bending and deforming or being squeezed and affecting the air permeability. The fixing member 163 of the air outlet 161 can not only prevent the outline of the air outlet 161 from deforming, but also fix the support member 162 inside the temperature regulating bag. For example, the fixing member 163 can use a riveting structure similar to a rivet or a pressing method to fix the support member 162 and the multi-layer structure of the temperature regulating bag together.

[0059] In some embodiments, the air outlet 161 is disposed on the branch air duct 152 located on the shoulder body 12 and above the main air duct 151. In this embodiment, the air outlet is designed at the shoulder area to blow air and adjust the temperature of the neck or head and cheeks. In other embodiments, the air outlet can also be disposed at the armpit or waist, etc., and can be adjusted arbitrarily according to the usage scenario.

[0060] In some embodiments, as shown in Figures 1, 5, and 8, a plurality of the air outlets 161 are arranged on opposite sides of the two shoulder bodies 12, facing the user's neck and cheeks. The neck area, with its superficial blood vessels connecting to the whole body, is one of the key areas for heat dissipation and maintaining comfort. By directing the airflow of the temperature-regulating bag towards the neck area, the wearer's perceived temperature can be quickly adjusted by lowering the temperature in this area. The neck area is typically prone to sweating, especially during exercise or in high-temperature environments. Providing temperature-regulating airflow to this area effectively promotes localized heat dissipation, reduces sweat buildup, and helps maintain dryness and comfort. The neck area is highly sensitive to body temperature; excessive heat or cold can affect overall comfort and health. Adjusting the airflow of the bag towards the neck area helps to promptly adjust the temperature in this area, avoiding discomfort. Directing the airflow of the temperature-regulating bag towards the neck area not only enhances comfort and experience but also effectively increases the product's practicality and effectiveness in various environments.

[0061] Furthermore, the air outlet 161 has an air outlet angle set between 0 and 90°. This air outlet angle can be based on the shoulder level or a zero-degree line; alternatively, the side of the air outlet 161 can have a certain angle to make it easier to direct air towards exposed skin such as the neck, cheeks, ears, and forehead, enhancing the temperature regulation effect. The number and size of the air outlets 161 can be adjusted according to actual conditions. In other embodiments, the air outlets 161 can also be located under the wearer's armpit or other areas. The air outlets 161 can also be any shape, such as circular, elliptical, oval, rectangular, or irregular, or a combination of any shapes.

[0062] In some embodiments, as shown in Figures 2-3, the aspect ratio of the main air duct of the bag body is 2:1-3:1. It is understood that the length of the main air duct referred to here is along the direction of airflow delivered by the fan, while the width is perpendicular to that direction. Since the cavity air duct has a cylindrical structure, the aspect ratio can also be called the length-to-diameter ratio. A main air duct with an aspect ratio of 2-3 times the diameter can achieve optimal airflow output, mainly for the following reasons:

[0063] Sufficient acceleration distance: Short ducts cannot provide enough acceleration time and space for the airflow, preventing the outlet wind speed from reaching its maximum. Conversely, excessively long ducts will lose some of their acceleration effect due to frictional losses. A main duct with a length-to-diameter ratio of 2-3 times allows the airflow to accelerate sufficiently, reaching the maximum outlet wind speed.

[0064] Reasonable static pressure drop: An appropriate duct length can create a large static pressure difference, generating strong suction. However, if it is too long, the static pressure drop will be too large, reducing overall efficiency. Setting the main duct to a length-to-diameter ratio of 2-3 times can achieve the optimal balance of static pressure difference.

[0065] Flow stability: Shorter ducts are easily affected by turbulence at the inlet, impacting airflow acceleration. Excessively long ducts, on the other hand, may experience flow separation. Setting the main duct to a length-to-diameter ratio of 2-3 times is beneficial for full airflow development and maintaining a stable flow state.

[0066] In summary, setting the main air duct to a length-to-diameter ratio of 2-3 times can fully utilize the principles of acceleration and static pressure drop while taking into account flow stability, thereby achieving maximum wind power output. This length ratio is the optimal design derived through extensive theoretical analysis and experimental verification.

[0067] In some embodiments, as shown in Figures 4 and 5, at least one temperature-regulating element mounting portion 14 is provided; in the case of multiple portions, as shown in Figure 8, the temperature-regulating element mounting portions 14 are arranged along the length or width direction of the main air duct 151. The temperature-regulating element mounting portion 14 can be configured as a mesh or similar structure, allowing for a larger contact area between the temperature-regulating element mounting portion 14 and the airflow within the cavity air duct 15, facilitating heat exchange and enhancing the temperature regulation effect. Multiple temperature-regulating element mounting portions 14 can accommodate multiple temperature-regulating elements, which helps to better change the temperature of the airflow, improving the overall temperature regulation effect and user comfort.

[0068] In some embodiments, as shown in FIG1, the temperature-regulating bag further includes at least one energy storage component mounting portion 17 for mounting an energy storage component. The energy storage component mounting portion 17 is located at the bottom of the shoulder body 12 or the back body 11 of the bag body. As shown in FIG1 and FIG6, if the energy storage component mounting portion 17 is located on the shoulder body 12 of the bag body, especially corresponding to the front chest area, it facilitates the operation of switching, adjusting the speed, and replacing the energy storage component. If the energy storage component mounting portion 17 is located at the bottom of the back body 11 of the bag body, it helps to lower the center of gravity and improve wearing comfort. When the energy storage component mounting portion 17 is located on the shoulder body 12 of the bag body, the bag body is provided with wiring channels 18 for embedding fan wires. These wiring channels 18 help to effectively arrange and connect the power supply and control circuits of the fan, and the embedding method helps to reduce the influence of the external environment and does not affect operation.

[0069] In some embodiments, as shown in Figures 1-3 and 9, the shoulder body 12 and / or back body 11 of the bag body are provided with connecting structures 19 for connecting to a waist tool bag 2 or a work belt. These connecting structures facilitate the user carrying the waist tool bag 2 or other accessories, increasing the bag's practicality and functionality. The connecting structure 19 can take various forms, such as a strap-like fastener used with Velcro, buckles, etc. (as shown in Figure 7), or a hook (as shown in Figure 1) or a ring structure. The tool bag can be a waist tool bag, a work belt, or a device for hanging items around the waist, and the connecting structure 19 can be located in the lower middle or bottom of the back body 11 of the bag body. To enhance stability, the connecting structure 19 can have multiple hanging points, such as being located at different positions at the front and back.

[0070] In the above embodiments, the main body of the bag serves as a connecting device for the tool bag and also has temperature regulation capabilities. Positioning the connecting structure 19 in the lower middle or bottom of the back body 11 helps stabilize the tool bag and reduces interference with the user's activities. This positioning better suits the design requirements of a waist-mounted tool bag, allowing it to easily attach to the lower part of the user's body for convenient operation and use. The Y-shaped structure of the main body also distributes the weight of the tool bag to the waist and shoulders, reducing pressure from a single support point and thus improving the overall stability of the bag. This is particularly important for users who wear the tool bag for extended periods, reducing shoulder strain and maintaining good balance. By distributing the weight to the waist and shoulders, shoulder fatigue and discomfort are reduced, allowing users to carry the tool bag more comfortably for work or activities, which is especially beneficial in work environments requiring prolonged standing or walking. The combination of the Y-shaped structure and the connecting design of the main body not only enhances stability and comfort but also further improves the practicality of the tool bag. For example, appropriate structural design can also ensure that the tool bag remains balanced during movement, reducing the possibility of swaying or shifting.

[0071] In some embodiments, as shown in FIG6, the shoulder body 12 of the bag body is provided with a plurality of straps 20 for securing the safety belt shoulder strap; the connection method of the straps 20 allows the safety belt shoulder strap and the bag body to be tightly connected, effectively distributing the weight, thereby improving the worker's work efficiency and safety.

[0072] In some embodiments, as shown in FIG1 or FIG4, the angle between the fan mounting portion 13 and the body surface of the bag facing the human body is 45-90°. This temperature-regulating bag optimizes the fan's position to effectively provide appropriate airflow to the user, thereby improving user comfort and convenience. By mounting the fan within this angle range, airflow can be more effectively guided to the desired location to provide heat dissipation or enhance ventilation. This angle selection takes into account ergonomics and user comfort, ensuring that the fan provides sufficient airflow without causing unnecessary discomfort or interference.

[0073] In some embodiments, as shown in Figures 4, 5, and 8, the bag body includes an outer layer 201, an insulation layer 202, a first sealing layer 203, a second sealing layer 204, a cushioning layer 205, and a breathable layer 206. The cavity between the first sealing layer 203 and the second sealing layer 204 forms the cavity air duct 15. The outer layer 201 is the outer fabric of the bag, possessing abrasion resistance, waterproofing, or other properties to protect the internal layers from the influence of the external environment; materials such as Oxford cloth can be used. The insulation layer 202 is used to maintain a stable internal temperature of the bag and prevent external temperatures from affecting the internal temperature regulating components. The insulation layer 202 can be made of materials such as pearl cotton. The first sealing layer 203 and the second sealing layer 204 are used to form the cavity air duct 15, and the space within can be designed or constructed to promote airflow or maintain a certain level of ventilation. The selection and arrangement of the sealing layers help maintain airflow pressure or humidity inside the bag. The first sealing layer 203 and the second sealing layer 204 can use fabrics with a breathable coating or similar structures. The cushioning layer 205 provides structural support, such as maintaining the overall shape of the temperature-regulating bag and ensuring the continuity of the air duct 15 within the cavity. It also helps the bag maintain its shape and stability under load. The cushioning layer 205 can be made of breathable padding, 3D mesh, 4D fibers, or other materials of a certain thickness. The breathable layer 206, as the layer in direct contact with the wearer, has a certain degree of breathability and flexibility to improve user comfort.

[0074] In some embodiments, the second sealing layer 204 may also have several ventilation holes, allowing temperature-regulating airflow to penetrate the back of the user through these ventilation holes, the buffer layer 205, and the breathable layer 206, providing a cooling sensation (when cooling is needed). This helps keep the back dry and provides adequate ventilation and cooling, making the user feel more comfortable. Effective air circulation, especially during exercise, work, or outdoor activities, can reduce the accumulation of moisture and heat on the back, thereby improving overall comfort and user experience.

[0075] In some embodiments, the cushioning layer 205 includes a breathable cushioning element; in other words, the cushioning element can be fully breathable or partially breathable. The cushioning layer 205 can use breathable rubber pads, three-dimensional mesh fabric, 4D fibers, or other materials of a certain thickness, which can be selected arbitrarily according to cost or application scenario.

[0076] In some embodiments, as shown in FIG4, the cushioning layer 205 may use two or more materials. Specifically, the cushioning layer 205 includes a first cushioning member 205A located on the back body 11 and a second cushioning member 205B located on the shoulder body 12. The first cushioning member 205A may be a breathable or non-breathable structure; the breathable structure may use 3D mesh fabric. The second cushioning member 205B may be a breathable or non-breathable structure; the non-breathable structure may use an EVA lining or a PVC lining. The second cushioning member 205B may be stiffer than the first cushioning member 205A to provide sufficient support strength and abrasion resistance in the shoulder area, thereby improving its service life. The EVA lining has moderate softness, suitable for prolonged carrying of temperature-controlled bags.

[0077] To suit various scenarios, the back body 11 of the temperature-regulating bag in this embodiment can have a short and wide structure, as shown in Figures 1-5; or it can have a long and thin structure, as shown in Figures 6-7. The long and thin structure of the temperature-regulating bag is suitable for scenarios requiring more storage space or a larger back coverage area. The long and thin back body 11 may cover more of the back area, providing greater capacity and better load distribution, suitable for extended outdoor activities or situations requiring the carrying of a large number of items. The short and wide structure of the temperature-regulating bag is more suitable for everyday lightweight use or scenarios requiring rapid movement. This design results in a shorter cavity air duct 15, less air pressure loss, greater air delivery effect, and a lighter and more convenient carrying experience.

[0078] In some embodiments of this disclosure, the temperature-regulating bag may have a longitudinal or transverse zipper or other opening mechanism on the back body 11 to allow for replacement of the temperature-regulating component after opening and closing the cavity air duct. The temperature-regulating bag may be equipped with connecting straps and buckles for easy wearing.

[0079] The temperature-regulating bag disclosed herein features improvements in air intake design, air duct design, and air blowing component design. These improvements enable the bag to provide comfortable airflow temperature regulation while worn. The various design improvements also contribute to maintaining efficient and stable airflow. The fan, mounted at the bottom of the bag, more effectively draws air in from below and pushes it to other parts of the bag without interfering with airflow when the user is carrying other items. The straight-through design of the main air duct minimizes resistance within the duct, allowing the fan-driven air to reach the target area more effectively, thereby improving airflow efficiency, providing maximum airflow for temperature regulation, and enhancing the temperature control effect.
