Description

Technical Field

[0001] The utility model relates to the technical field of bags worn by human bodies, in particular to a temperature regulating bag. Background Art

[0002] In recent years, with the increasing global warming and extreme high temperature weather in summer, the market demand for portable temperature control equipment has continued to expand. In addition to general consumers, commercial hot places (such as construction sites, warehouses, factories) and specific industries (such as outdoor work, outdoor sports, sports express delivery, etc.) have become the main application areas. Initially, the current portable temperature control equipment was mainly based on traditional fans for air supply, relying on increasing the number of fans or fan power to increase wind force to provide a greater cooling effect. However, this put forward higher requirements on the fan capacity and battery capacity. Due to the limitations of current technology, increasing wind force has limited effect on improving cooling and has corresponding disadvantages: such as the increase in battery weight increases the burden on users, the noise generated by high-power fans, environmental protection and cost issues, etc.

[0003] In addition, the fan clothing expands due to the wind when in use, and cannot effectively connect to the work tools (work belt and tool bag, etc.) worn around the waist, which causes inconvenience to a certain extent and affects work efficiency.

[0004] Fan clothing is greatly affected by the external environment temperature, and has limited or no effect in high temperature environments. For example, in the hot summer, it is often difficult for users to effectively reduce their body temperature by relying solely on the fan blowing method of fan clothing. In fact, the introduction of high-temperature airflow will make users feel more uncomfortable, and users will also be more easily fatigued due to the added weight of portable temperature control equipment.

[0005] The design of the air inlet, air duct and blowing part of portable thermostats will affect the temperature control effect. For example, the air inlet of portable thermostats is not in a reasonable position or is easily blocked, and the air duct is not clear, which hinders the air flow and affects the cooling effect.

[0006] Therefore, in order to remedy and improve the above problems of traditional fan clothing, such as limited cooling effect and unreasonable design, it is very important to provide a more effective and portable local cooling solution. Utility Model Content

[0043] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the implementation mode and the accompanying drawings. Here, the schematic implementation mode of the utility model and its description are used to explain the utility model, but are not used as a limitation of the utility model.

[0044] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0045] It should be emphasized that the term “include / comprises” when used herein refers to the presence of features, elements, steps or components, but does not exclude the presence or addition of one or more other features, elements, steps or components.

[0046] It should also be noted that, unless otherwise specified, the term “connection” herein may refer not only to a direct connection but also to an indirect connection with an intermediate.

[0047] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0048] The utility model aims to provide a portable solution that can adjust the temperature of airflow, which is suitable for use in situations where a comfortable temperature needs to be maintained in a specific environment. The temperature-regulating bag has improved the air inlet design, air duct design, and blowing part design, so that the temperature-regulating bag can provide a comfortable airflow temperature regulation function when worn. Various improved designs are also conducive to the temperature-regulating bag to maintain the high efficiency and stability of air flow, and bring convenience to various usage scenarios.

[0049] like Figure 1-Figure 3As shown, the temperature regulating bag has a bag body for being worn on a human body, and the bag body includes: a fan mounting portion 13, a temperature regulating component mounting portion 14, a cavity air duct 15, an air outlet portion 16, etc.

[0050] The fan mounting portion 13 is located at the bottom of the bag body and is used for fixedly mounting or detachably mounting the fan.

[0051] The cavity air duct 15 is located inside the bag body and is connected to the fan mounting portion 13 and the air outlet portion 16, and is used as an air supply channel. The air supply channel should be designed to be sufficiently smooth or straight to avoid wind pressure loss and ensure sufficient wind pressure.

[0052] The thermostat installation part 14 is located in the cavity air duct 15, and after the thermostat is installed, it is used to change the temperature of the air flow passing through the cavity air duct 15; it can be understood that the thermostat 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 bag, a frozen water bottle or a Peltier device, etc., and the heat source can be an electric heater, a heating pad or a thermoelectric effect device, etc.

[0053] The cavity air duct 15 includes a main air duct 151. When worn, the main air duct 151 is a straight channel to ensure that the airflow can flow smoothly to the air outlet 16. The air outlet 16 is located on one side or the top of the bag body and is used to release the airflow after temperature adjustment.

[0054] In the above embodiment, the temperature regulating bag can be worn on the user's body, and the fan installed at the bottom of the temperature regulating bag can more effectively draw in air from the bottom and push it to other parts of the bag. This arrangement helps to create a good airflow path, making the air circulation of the entire system smoother. Installing the fan at the bottom of the temperature regulating bag can increase the stability and balance of the temperature regulating bag. The bottom of the temperature regulating bag can be one end of the bag, which can provide sufficient support to prevent the bag from vibrating or shaking due to the operation of the fan. The fan installed at the bottom of the temperature regulating bag will not affect the air intake affected by the user carrying other items, such as the need to carry a tool bag or production materials and tools.

[0055] In the above embodiment, the main air duct 151 is a straight channel (or straight-through design) with many advantages. The straight-through design can minimize the resistance in the air duct because the air does not need to change direction at multiple turns or branches. This ensures that the air flow and speed blown out by the fan will not be reduced due to resistance loss, thereby improving the overall fan efficiency and performance, thereby reducing energy consumption and extending the service life of the equipment. The straight-through design can ensure that the flow of air in the air duct is straight, avoiding uneven or turbulent flow caused by twists or bifurcations. Since the straight-through design reduces the resistance and uneven flow of air in the air duct, the generation of noise can also be reduced. The straight-through design allows the air pushed by the fan to reach the target area more effectively, thereby improving the overall air flow efficiency. The straight-through design can make the air duct easier to clean and less likely to harbor dirt and breed bacteria.

[0056] In some embodiments, Figure 1-Figure 3 As shown, the bag body is in a Y-shaped structure, including two shoulder bodies 12 located at the branch parts and a back body 11 located at the trunk part, thereby forming a backpack shape that can be carried on the back. The bag body with a Y-shaped structure is divided into a shoulder and a back body 11, which can better fit the shoulder and back curves of the human body and provide a more comfortable wearing experience. This design takes ergonomics into consideration and is easier to carry, making the bag more fitting and stable when in use. The Y-shaped structure is not only suitable for daily wear, but also can be used in environments that require specific temperature control, such as outdoor sports, medical care or special working environments.

[0057] The cavity air duct 15 further includes a branch air duct 152, the branch air duct 152 is located at the shoulder body 12, the main channel is located at the back body 11, and 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 finally released through the air outlet 16, thereby ensuring the efficiency and uniformity of air circulation.

[0058] 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 position of the air outlet 161, and the height of the support member 162 is greater than the size of the air outlet 161 in the thickness direction of the shoulder body 12, and is used to support the air outlet 161 in the thickness direction of the shoulder body 12 to always keep it in an open state. Figure 4 or Figure 8As shown, the support member 162 can be a semicircular support tube or other shapes with an open structure on one side, and its curved surface, vertical surface, inclined surface, etc. are close to one side of the bag body, which is used to support the air outlet 161 to ensure that it remains in an open state when the shoulder body is bent. It can also ensure that when the bag is in a specific use environment, such as sports, movement or various operations, the air outlet 161 can always maintain a relatively stable air outlet angle and patency, thereby ensuring the air circulation effect and the stability of temperature regulation.

[0059] In addition, the air outlet 161 may also be provided with a fixing member 163, which 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 may be made of metal or plastic material, 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 an open state.

[0060] In the above embodiment, the support member 162 is mainly used to prevent the branch air duct 152 of the temperature-regulating bag from bending, deforming or being squeezed to affect ventilation, and the fixing member 163 of the air outlet 161 can not only prevent the contour of the air outlet 161 from being deformed, but also fix the support member 162 in 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-layered structure of the temperature-regulating bag together.

[0061] In some embodiments, the air outlet 161 is arranged on the branch air duct 152 located on the shoulder body 12, and is located above the main air duct 151. In this embodiment, the air outlet is designed at the shoulder position, and can blow air to adjust the temperature of the neck or head cheek of the human body. In other embodiments, the air outlet can also be set at the armpit or waist and other positions at the same time, and can be adjusted arbitrarily according to the usage scenario.

[0062] In some embodiments, Figure 1 , Figure 5 and Figure 8As shown, several of the air outlets 161 are arranged on the sides of the two shoulder bodies 12 facing each other, so as to face the neck and cheeks of the user. The neck is one of the key areas for heat dissipation and comfort maintenance because the blood vessels are shallow and lead to the whole body. By directing the airflow of the thermostatic bag toward the neck, the wearer's body temperature can be quickly adjusted by lowering the temperature of this area. The neck is usually prone to sweating, especially during exercise or in high temperature environments. By providing thermostatic airflow to this area, local heat dissipation can be effectively promoted, sweat accumulation can be reduced, and it helps to stay dry and comfortable. The neck is highly sensitive to body temperature, and overheating or overcooling may affect overall comfort and health. Adjusting the bag airflow toward the neck can help adjust the temperature of this area in time to avoid discomfort. Directing the airflow of the thermostatic bag toward the neck not only helps to improve comfort and experience, but also effectively enhances the practicality and effectiveness of the product in various environments.

[0063] Furthermore, the outlet angle of the air outlet 161 is set to 0-90°, where the outlet angle can be based on the shoulder horizontal line as a reference or zero-degree line; or, the side where the air outlet 161 is located can also have a certain slope, so that it is easier to face the exposed skin of the human body in the neck, cheeks, ears, forehead, etc., to enhance the temperature regulation effect. The number of air outlets 161, the size of the opening, etc. can be adjusted according to actual conditions. In addition, in other embodiments, the air outlet 161 can also be set at the armpit or other parts corresponding to the wearer. The air outlet 161 can also be set to any shape, such as a circle, an ellipse, a waist circle, a rectangle or an irregular shape, etc., or a combination of any shapes.

[0064] In some embodiments, Figure 2-Figure 3 As shown, the length-to-width ratio of the main air duct of the bag body is 2:1-3:1. It can be understood that the length of the main air duct mentioned here refers to the direction of the air flow delivered by the fan, and the width is perpendicular to this direction. Since the cavity air duct is a cylindrical structure, the length-to-width ratio can also be called the length-to-diameter ratio. The main air duct with a length-to-diameter ratio of 2-3 times can achieve the best wind output, mainly for the following reasons:

[0065] Sufficient acceleration distance: A short air duct cannot provide enough acceleration time and space for the airflow, so the wind speed at the outlet cannot reach the maximum value. An overly long air duct will offset part of the acceleration effect due to friction loss. A trunk air duct with a length-to-diameter ratio of 2-3 times can fully accelerate the airflow and reach the highest outlet wind speed.

[0066] Reasonable static pressure drop: Appropriate duct length can create a larger static pressure difference and generate strong suction. But if it is too long, the static pressure drop will be too large and reduce the overall efficiency. Setting the main duct to 2-3 times the length-to-diameter ratio can achieve the best static pressure difference balance.

[0067] Flow stability: Shorter air ducts are easily affected by turbulence at the entrance, which affects the acceleration effect of the airflow. Too long air ducts may cause problems such as flow separation. Setting the main air duct to a length-to-diameter ratio of 2-3 times is conducive to the full development of the airflow and maintaining a stable flow state.

[0068] In summary, setting the main air duct to a 2-3 times length-to-diameter ratio can fully utilize the principles of acceleration and static pressure drop while taking into account flow stability, thereby obtaining the maximum wind output. This length ratio is the best design obtained through a large amount of theoretical analysis and experimental verification.

[0069] In some embodiments, Figure 4 and Figure 5 As shown, the temperature adjustment component installation portion 14 is provided with at least one; in the case where multiple temperature adjustment components are provided, as shown in FIG. Figure 8 As shown, the thermostat mounting portion 14 is arranged along the length or width direction of the main air duct 151. The thermostat mounting portion 14 can be set as a structure such as a net bag, so that the thermostat mounting portion 14 has a larger contact area with the airflow in the cavity air duct 15, making it easier to perform heat exchange and enhancing the temperature adjustment effect. Multiple thermostat mounting portions 14 can be installed with multiple thermostats, which helps to better change the temperature of the airflow passing through, improve the overall temperature adjustment effect and user comfort.

[0070] In some embodiments, Figure 1 As shown, the temperature regulating bag further includes at least one energy storage component installation portion 17 for installing the energy storage component, and the energy storage component installation portion 17 is located at the bottom of the shoulder body 12 or the back body 11 of the bag body. Figure 1 and Figure 6 As shown, if the energy storage component mounting portion 17 is arranged on the shoulder body 12 of the bag body, especially corresponding to the front chest area of ​​the human body, it is convenient for personnel to operate switches, gear adjustments and replacement of energy storage components. If the energy storage component mounting portion 17 is arranged at the bottom of the back body 11 of the bag body, it is beneficial to lower the center of gravity and provide high wearing comfort. In the case where the energy storage component mounting portion 17 is located at the shoulder body 12 of the bag body, a line channel 18 for burying fan wires is provided in the bag body. These line channels 18 can help to effectively arrange and connect the power supply and control circuits of the fan, and the burying method is beneficial to reduce the impact of the external environment and does not affect the operation.

[0071] In some embodiments, Figure 1-Figure 3 and Fig. 9As shown, the shoulder body 12 and / or the back body 11 of the bag body are provided with a connection structure 19 for connecting with the waist tool bag 2 or a working belt. The function of these connection structures is to facilitate the user to carry the waist tool bag 2 or other accessories, so as to increase the practicality and functionality of the bag. The connection structure 19 can be in various forms, such as a belt-shaped fastener (such as a Velcro, a buckle, etc.) used in conjunction with Figure 7 As shown), it can also be a hook (as Figure 1 The tool bag can be a waist tool bag, a work belt or a waist hanging item, and the connecting structure 19 can be arranged at the middle and lower part or the 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 arranged at different positions at the front and back.

[0072] In the above embodiment, the bag body serves as a connecting device of the tool bag and has the ability to regulate temperature. The connection structure 19 is arranged at the middle and lower part or the bottom of the back body 11, which helps to stabilize the tool bag and reduce interference with the user's activities. Such a position is more in line with the design requirements of the waist tool bag, so that the tool bag can be easily attached to the lower part of the user's body, which is convenient for operating and using the tool. The Y-shaped structure of the bag body also allows the gravity of the tool bag to be dispersed to the waist and shoulders of the human body, reducing the pressure caused by a single fulcrum, thereby improving the overall stability of the bag. This is particularly important for users who wear the tool bag for a long time, which can reduce the burden on the shoulders while maintaining a good sense of balance. By dispersing the gravity points to the waist and shoulders, the fatigue and discomfort of the shoulders can be reduced, allowing the user to carry the tool bag more comfortably for work or activities, which is particularly beneficial for work environments that require standing or walking for a long time. Combining the Y-shaped structure and the connection design of the bag body, not only the stability and comfort are enhanced, but also the practicality of the tool bag can be further improved. For example, appropriate structural design can also ensure that the tool bag remains balanced during movement and reduce the possibility of shaking or displacement.

[0073] In some embodiments, Figure 6 As shown, the shoulder body 12 of the bag body is provided with a plurality of straps 20 for fixing the safety belt shoulder straps; the connection method of the straps 20 allows the safety belt shoulder straps and the bag body to be closely combined, effectively dispersing the weight, thereby improving the work efficiency and safety of the worker.

[0074] In some embodiments, Figure 1 or Figure 4As shown, the angle between the fan mounting portion 13 and the body-facing surface of the bag body is 45-90°. The temperature-regulating bag optimizes the position of the fan so that it can effectively provide appropriate airflow to the human body, thereby improving the comfort and convenience of the user. By installing the fan within this angle range, the air flow can be more effectively guided to the desired location to provide heat dissipation or enhance ventilation. The selection of this angle takes into account ergonomics and user comfort, ensuring that the fan can provide sufficient air flow without causing unnecessary discomfort or interference.

[0075] In some embodiments, Figure 4 , Figure 5 and Figure 8 As shown, the bag body includes an outer layer 201, an insulation layer 202, a first sealing layer 203, a second sealing layer 204, a buffer layer 205 and a breathable layer 206, and 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, which has wear resistance, waterproof or other characteristics, protects the internal layers from the influence of the external environment, and can use materials such as Oxford cloth. The insulation layer 202 is used to maintain the stability of the internal temperature of the bag and prevent the external temperature from affecting the internal temperature regulating parts. The insulation layer 202 can use materials such as pearl cotton, and the first sealing layer 203 and the second sealing layer 204 are used to form the cavity air duct 15, in which the space can promote air flow or maintain a certain ventilation effect through some structures or designs. The selection and arrangement of the sealing layer helps to maintain the air flow pressure or humidity inside the bag. The first sealing layer 203 and the second sealing layer 204 can use structures such as cloth with an anti-breathable coating. The buffer layer 205 is used to provide structural support, such as the overall shape of the temperature-regulating bag and the penetration of the cavity air duct 15, and can also ensure that the bag maintains its shape and stability under load. The buffer layer 205 can use breathable rubber pads, three-dimensional mesh fabrics, 4D fibers, or other materials of a certain thickness. The breathable layer 206, as a layer in direct contact with the wearer, has a certain breathability and flexibility to improve the comfort of the user.

[0076] In some embodiments, the second sealing layer 204 may also be provided with a plurality of air holes, so that the temperature-adjusting airflow can penetrate into the back of the human body through the air holes, the buffer layer 205 and the air-permeable layer 206, bringing a cool feeling to the back of the human body (when cooling is required), helping to keep the back dry and properly ventilated and cooled, making the user feel more comfortable. Through effective air circulation, especially during exercise, work or outdoor activities, the moisture and heat accumulated on the back can be reduced, thereby improving the overall comfort and user experience.

[0077] In some embodiments, the buffer layer 205 includes a breathable buffer, in other words, the buffer can be fully breathable or partially breathable. The buffer layer 205 can be made of breathable rubber pads, three-dimensional mesh, 4D fibers, or other materials of a certain thickness, which can be selected according to their cost or application scenarios.

[0078] In some embodiments, Figure 4 As shown, the buffer layer 205 can be made of two or more materials. Specifically, the buffer layer 205 includes a first buffer 205A located at the back body 11 and a second buffer 205B located at the shoulder body 12. The first buffer 205A is a breathable structure or a non-breathable structure, and the breathable structure can use a 3D mesh cloth. The second buffer 205B is a breathable structure or a non-breathable structure, and the non-breathable structure can use an EVA lining or a PVC lining. The second buffer 205B can be harder than the first buffer 205A, so as to provide sufficient support strength and wear resistance at the shoulder and improve the service life.
