[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the embodiments and the accompanying drawings. Herein, the schematic embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0047] It should also be noted herein that, in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, and other details having little relation to the present invention are omitted.

[0049] It should also be noted herein that, unless otherwise specified, the term “connect” as used herein may refer to direct connection or indirect connection with an intermediate object existing.

[0050] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference signs represent the same or similar components or the same or similar steps.

[0051] The embodiment of the present invention provides a portable temperature-regulating device (backpack-mounted or chest-worn type), which is mainly in the form of a front-worn chest bag or a rear-worn backpack, and can be conveniently worn on the user's body through the structure of the shoulder straps (12). The use scenarios include outdoor activities, sports or working environments, and it is particularly suitable for use in high-temperature environments.

[0052] The embodiment of the present invention provides a portable temperature-regulating device (backpack-mounted or chest-worn type), as shown in FIGS. 1 and 2, comprising a bag body (11) and at least two shoulder straps (12). The shoulder straps (12) are connected to the upper part of the bag body (11) and serve to wear the bag body (11) on the user's shoulders or chest.

[0053] The bag body (11) is provided with an air inlet (112) and a main cavity air duct (113); a fan mounting part (114) and a temperature-regulating element mounting part (115) are arranged on the main cavity air duct (113), such that after a fan (31) and a temperature-regulating element (32) are mounted on the fan mounting part (114) and the temperature-regulating element mounting part (115) respectively, the airflow entering the main cavity air duct (113) from the air inlet (112) forms a temperature-regulated airflow. Each shoulder strap (12) is provided with a branch cavity air duct (121) and at least one air outlet hole (122); the branch cavity air duct (121) is in communication with the main cavity air duct (113), enabling the temperature-regulated airflow to enter the branch cavity air duct (121) and be jetted from the air outlet hole (122) to the temperature-sensitive areas of the user requiring temperature regulation.

[0054] In the above embodiment, the temperature-regulating device is in the form of a backpack or a chest bag, and the bag body (11) and the shoulder straps (12) form a through cavity. The air inlet (112) of the bag body (11) can be arranged at the middle or two sides of the bottom; the fan (31) can be arranged at the position of the air inlet (112) of the main cavity air duct (113) of the bag body (11) or inside the main cavity air duct (113). The temperature-regulating element (32) can be mounted in the main cavity air duct (113), and the temperature-regulating element (32) cools or heats the airflow introduced into the main cavity air duct (113) by the fan (31) to form a temperature-regulated airflow. The whole cavity is filled with the temperature-regulated airflow to form a temperature storage area; the temperature-regulated airflow in the temperature storage area forms a pressure difference with the outside due to the continuous air suction of the fan (31), thus being jetted from the air outlet hole (122) to the temperature-sensitive areas of the human body requiring temperature regulation.

[0055] Compared with the conventional garment-type wearable temperature-regulating device, referring to FIG. 3, the temperature-regulating device in the embodiment of the present invention is in the form of a backpack or a chest bag. The backpack design concentrates the weight of the device on the back and shoulders, and the chest bag design concentrates the weight on the chest and shoulders. The backpack or chest bag structure not only provides a good load distribution for the body, making the user more flexible in activities and suitable for outdoor sports or work, but also provides a large storage space, which can hold temperature-regulating elements of various sizes and weights, such as cold drinks, hot drinks, ice pack coolants, warm patches, thermoelectric effect devices and even micro air conditioners. Compared with the open structure of traditional air-conditioned clothes, the temperature-regulating device has a closed temperature storage cavity, so as to store and transport the temperature-regulated airflow generated by the temperature-regulating elements. Through the through design of the branch cavity air duct of the shoulder strap and the main cavity air duct of the bag body, the temperature-regulated airflow can be efficiently transported and blown to the temperature-sensitive areas of the human body (such as the head and neck); through the air penetration structure on the back of the bag body, the back (chest) of the human body can also obtain a suitable temperature feeling, thus comprehensively adjusting and balancing the body temperature of the upper body (including the head and neck) and greatly improving the temperature-regulating capacity and efficiency.

[0056] In some embodiments, as shown in FIGS. 1-4, two shoulder straps (12) are provided, which are respectively arranged on two sides of the top of the bag body (11); the air outlet holes (122) are formed on the mutually facing sides of the two shoulder straps (12), such that the air outlet holes (122) face the user's neck or head. In this embodiment, taking a hot environment as an example, the head and neck are regarded as the temperature-sensitive areas of the user; these parts are generally exposed, and direct blowing of cool air to these parts can quickly bring a strong cooling feeling to the human body, thus greatly improving the cooling efficiency. Compared with the indirect cooling mode of traditional air-conditioned clothes through evaporating sweat by vaporization heat, this temperature-regulating mode adopts the direct blowing mode of temperature-regulated airflow, which greatly reduces the heat resistance burden of the body and brings a comfortable cooling effect to the user.

[0057] In addition, in order to enhance the airflow permeability of the branch cavity air duct (121) of the shoulder strap (12), a pressure-resistant design can be carried out on the branch cavity air duct (121) of the shoulder strap (12), such as using a support material to prop up the branch cavity air duct (121) or embedding a pipe structure for airflow passing. The pressure-resistant design also allows the user to move freely, and at the same time ensures the unobstructed air duct of the shoulder and avoids airflow blockage. Similarly, the main cavity air duct (113) of the bag body (11) can also be designed with corresponding pressure resistance to ensure that the air duct can keep through under any circumstances and improve the stability of the device.

[0058] As at least one realizable mode, as shown in FIGS. 8-9, the temperature-regulating device further comprises a support member (21) arranged in the branch cavity air duct (121) of the shoulder strap (12). The support member (21) can use a support material with certain rigidity, flexibility and toughness, and the material can be selected from leather, artificial leather, PVC sheet or mesh, metal sheet or mesh, etc., which is used to support the branch cavity air duct (121) so that the branch cavity air duct (121) is always kept in an open state and a required air outlet angle is maintained. For example, materials such as leather and artificial leather can be sewn in the interlayer of the shoulder strap or serve as the direct contact layer of the branch cavity air duct (121); due to their own characteristics, these materials can ensure that the shoulder can bend when worn, and also ensure the pressure resistance and support strength of the branch cavity air duct to a certain extent. Further, the cross-sectional shape of the support member (21) or the branch cavity air duct (121) formed by fixing the layered support material around for a circle can be diversified, such as drop shape, triangle, quadrilateral, circle or ellipse, and the shape embodiments can refer to FIGS. 8 and 9, but are not limited thereto. It can be understood that, in order to reduce wind pressure loss, the support member (21) or the branch cavity air duct (121) can be made as smooth as possible, shape mutations are reduced, and adjacent sides are transitioned by fillets or smooth curves.

[0059] As another realizable mode, as shown in FIGS. 7, 9 and 10, the support member (21) can also use a pipe structure with certain rigidity, flexibility and toughness, such as formed pipes made of PP, PVC, PE and other materials, and these formed pipes can be fixed in the branch cavity air duct (121) by fixing parts. Further, the support member (21) is a semi-tubular structure or a full-tubular structure clamped in the shoulder strap, that is, if the support member (21) is a semi-tubular structure, the inner space of the pipe serves as a part of the branch cavity air duct (121); if the support member (21) is a full-tubular structure, the inner space of the pipe is the entire branch cavity air duct (121). The semi-tubular structure mentioned herein can be formed by splitting a complete pipe, or an arc pipe with a circular arc degree of ⅓-⅔.

[0060] In the above realizable mode, the support member (21) can be used as a pressure-resistant part of the branch cavity air duct (121) of the shoulder strap (12) and also as a pressure-resistant part of the air outlet hole (122). The support member (21) serves as a pressure-resistant part of both the cavity and the air outlet hole (122) at the same time, which improves the overall structural strength of the shoulder strap (12) and the air duct and increases durability. The support member (21) ensures that the branch cavity air duct (121) and the air outlet hole (122) are always kept in an open state, avoiding air duct blockage caused by compression, thus maintaining stable airflow. By designing a proper air outlet angle, the efficiency of air circulation can be effectively improved, and the air can directly act on the areas where the user needs cooling most. As shown in FIG. 7, the inner side surface (the right side surface in the figure) of the shoulder strap (12) is designed as an inclined surface, which facilitates the air blowing angle to be inclined upward to directly blow the neck and head (including cheeks, ears, forehead and other parts).

[0061] Further, as shown in FIGS. 7-8, the support member (21) is provided with open holes (211) corresponding to the air outlet holes (122). The support member (21) is arranged on part or all of the inner side wall of the cavity where the air outlet holes (122) of the branch cavity air duct (121) are located, or arranged in the interlayer position of part or all of the shoulder strap (12). The support member (21) in the embodiment of FIG. 7 is arranged in the cavity, which is convenient for fixing and installation; the support member (21) in the embodiment of FIG. 8 serves as a layered structure of part or all of the shoulder strap (such as leather or artificial leather sewn on the innermost side of the shoulder strap), which can serve as a cavity air duct contact layer of the branch cavity air duct (121). Alternatively, the support member (21) can also be arranged in the interlayer of the shoulder strap, such as sewn and clamped for fixation, and the fixing mode is firm and compact. Optionally, the support member (21) can be fixedly arranged between the outer surface layer (101) and the top layer of the cavity air duct (103).

[0062] Further, as shown in FIGS. 7-10, the temperature-regulating device further comprises a fixing ring (22) arranged at the position of the air outlet hole (122); the fixing ring (22) is buckled on the inner edge of the air outlet hole (122) and is clamped and connected with the support member (21), such that the support member (21) is fixed on the side wall of the branch cavity air duct (121) of the shoulder strap (12), the air outlet hole (122) is always kept in a stable open state, and a required air outlet angle is maintained at the same time. This structure makes the support member (21) easy to install and disassemble, and also easy to ensure sufficient connection strength and stability with fewer structural parts.

[0063] Further, as shown in FIG. 11, the cross-sectional shape of the support member (21) is set to a semicircle, a semi-ellipse, a triangle or a rectangle; the support member (21) is provided with a non-closed structure on the side far away from the air outlet hole (122), and this part is used to communicate with the cavity of the branch cavity air duct (121). The arrangement of the open hole (211) ensures that air can flow out smoothly; at the same time, the diversity of cross-sectional shapes (such as triangle or semicircle) can effectively guide the airflow and improve the air supply effect. The non-closed structure reduces the weight while maintaining the stability of the support member (21).

[0064] As shown in FIG. 11, when the cross-sectional shape of the support member (21) is set to a triangle, the support member (21) is provided with a curved surface or an inclined surface on the side where the air outlet hole (122) is located; the design of the curved surface or inclined surface can better fit ergonomics, reduce the sense of oppression on the body and improve the wearing experience. The design of the curved surface or inclined surface is also conducive to smoothly guiding the airflow to converge to the air outlet hole (122) and reducing wind pressure loss. Optionally, the inner wall of the support member (21) is smooth to avoid wind pressure loss.

[0065] In some embodiments, as shown in FIG. 11, the number of the air outlet holes (122) is one or more, and the shape thereof includes at least one of a circle, an ellipse, an oblong and a polygon. Optionally, a plurality of air outlet holes (122) are arranged on the shoulder strap (12) and arranged on the inner side surface of the shoulder strap (12) according to a certain arrangement mode (such as equal interval).

[0066] A plurality of air outlet holes (122) can increase the airflow circulation area and the air blowing action area, and can fully cover the user's neck and head, which can not only ensure the overall ventilation efficiency, but also ensure that the user obtains the best temperature-regulating effect. The design of various shapes of the air outlet holes (122) can meet different airflow requirements and improve the use flexibility; the diversity of shapes provides a variety of choices and can also improve the design aesthetic feeling of the device.

[0067] In some embodiments, the opening width or diameter of the air outlet hole (122) is designed to be 4-60 mm, or the opening area of the air outlet hole (122) is designed to be 12-100 square millimeters. The design of the air outlet holes (122) with these sizes can effectively control the speed and flow of the jet airflow and improve the cooling or heating effect. Air outlet holes (122) of different sizes provide a variety of air volume choices, which are suitable for different environments and use scenarios and meet the specific needs of users. Specifically, the design of smaller or fewer orifices can appropriately increase the airflow pressure difference at the inlet and outlet, that is, the introduced airflow can stay in the cavity air duct of the device for a sufficient time for cooling and heating, and can form a sufficient air pressure difference with the outside, thus forming a strong jet airflow.

[0068] In some embodiments, both the bag body (11) and the shoulder straps (12) comprise a bottom composite layer and a top composite layer; the bottom composite layer is the side facing the user, and the top composite layer is the side facing away from the user; the bottom composite layer and the top composite layer are connected to enclose the main cavity air duct (113) and the branch cavity air duct (121).

[0069] The temperature-regulating device in the embodiment of the present invention can not only discharge air at the shoulder, but also at the armpit or waist. As shown in FIGS. 2-4 and 15-16, the temperature-regulating device is in the form of a vest backpack, which comprises air outlet holes (122) at the shoulder and second air outlet holes (122b) at the waist or armpit. The front of the backpack can also be provided with an opening structure of the cavity such as a zipper (41) to facilitate storing articles and replacing temperature-regulating elements.

[0070] Referring to FIG. 6, the temperature-sensitive areas of the human body requiring temperature regulation can be divided into three parts, namely a first temperature-regulating area at the head and neck, a second temperature-regulating area at the armpit and a third temperature-regulating area covering the entire back. The temperature-regulating device in the embodiment of the present invention is provided with air outlet holes at the shoulder, which can blow air for temperature regulation to the first temperature-regulating area; second air outlet holes (122b) are arranged at the armpit, which can blow air for temperature regulation to the second temperature-regulating area; a temperature storage area is formed at the back area, which can perform air seepage and diffusion temperature regulation on the third temperature-regulating area.

[0071] The bag body (11) and the shoulder straps (12) of the temperature-regulating device in the embodiment of the present invention can be of a multi-layer structure. In some embodiments, as shown in FIG. 1, the top composite layer comprises an outer surface layer (101) and a top layer of the cavity air duct (103) arranged layer by layer from outside to inside; the outer surface layer (101) is used to provide external protection for the temperature-regulating device, and the top layer of the cavity air duct (103) is used to prevent the temperature-regulated airflow in the cavity from overflowing. Optionally, the outer surface layer (101) can adopt a wear-resistant fabric, such as Oxford fabric. In case of special needs, the outer surface layer (101) can adopt a special heat-resistant, heat-insulating and flame-retardant material, such as a special material that can reflect ultraviolet rays and reduce the absorption of external environmental heat. The top layer of the cavity air duct (103) can adopt a fabric material with good air tightness, such as resin-coated fabric; in the case of cooling, the coating is reflective silver, which not only plays a sealing role, but also can reflect ultraviolet rays and reduce the absorption of external environmental heat. The TPU silver film reflective cloth not only avoids gas leakage, but also can refract the radiation of heat / cold of the temperature-regulating element.

[0072] Further, a heat insulation layer (102) is further arranged between the outer surface layer (101) and the top layer of the cavity air duct (103); the heat insulation layer (102) is arranged to cover at least a part of the bag body (11) or the shoulder strap (12).
