Description

Technical Field

[0001] This utility model relates to the field of wearable cooling device technology, and in particular to wearable cooling devices that can be used in combination. Background Technology

[0002] Currently, there are two main types of cooling devices available on the market for outdoor use in summer: cooling backpacks and air-conditioned clothing.

[0003] Cooling backpacks primarily employ either air cooling or semiconductor cooling technologies, as illustrated in patent documents CN218302766U, CN219165867U, and CN115251493A. The advantage of these products and technologies is that they cool the back of the user while still allowing for the storage of items inside. However, their disadvantage is that they only cool the back and cannot cool the front of the user.

[0004] Similarly, air-conditioned clothing generally employs either air cooling or semiconductor cooling technologies. For example, existing patent documents CN216821880U, CN215837276U, and CN213549792U demonstrate this. The advantage of these products and technologies is that they can cool a larger area of ​​the body using fans or semiconductor cooling elements, achieving a cooling effect on the back and chest. However, their disadvantage is the need for a wider range of sizes to accommodate consumers of different heights and body types. This wider range of sizes presents challenges for manufacturers, requiring them to prepare large quantities of fabric in various sizes, leading to a significant increase in material and processing costs.

[0005] In addition, the common drawback of the two products and technical solutions mentioned above is that the products have a single application scenario and cannot be flexibly applied to multiple scenarios.

[0006] Therefore, a new technical solution is needed to address the shortcomings of the aforementioned products and provide a new cooling device that can provide cooling for the upper body from both the front and back, while minimizing size requirements and enabling flexible combination of uses, thereby enriching the product's usage scenarios. Summary of the Invention

[0007] The purpose of this invention is to address the deficiencies in the prior art and provide a wearable cooling device that can be used in combination, enabling large-area heat dissipation from the front and back of the upper body. It is also versatile in various application scenarios and reduces the inconvenience caused by size requirements.

[0008] The objective of this utility model is achieved through the following means:

[0009] A wearable cooling device that can be used in combination includes a first cooling component and a second cooling component, which cools the upper body from front to back. The first and second cooling components have detachable connecting devices on their upper left and right sides, allowing them to be movably connected at the upper end, with the connection points located on the shoulders. The first and second connecting devices are located on the lower left and right sides of the first cooling component, respectively. The second and third connecting devices are located on the lower left and right sides of the second cooling component, respectively. The first and third connecting devices are movably connected, as are the second and fourth connecting devices, for securing the device to the body. This connection technology allows the cooling device to be used by people of various body types, and the movable connections enable immediate adjustment of the cooling device, making it easy to use.

[0010] In the above description, as a preferred embodiment, the length of the detachable connecting device can extend from the upper end of the first refrigeration component to below the first connecting device or the second connecting device, and can respectively form a movable connection with the first connecting device or the second connecting device.

[0011] In the above description, as a preferred embodiment, the detachable connecting device is provided with a strap hole at its lower end, through which either the first connecting device or the second connecting device can pass.

[0012] In the above description, as a preferred embodiment, the length of the detachable connecting device can extend from the upper end of the second refrigeration component to below the third or fourth connecting device, and can respectively form a movable connection with the third or fourth connecting device.

[0013] In the above description, as a preferred embodiment, the first connecting device and the second connecting device can form a movable connection structure, and the third connecting device and the fourth connecting device can form a movable connection structure.

[0014] In the above description, as a preferred embodiment, the detachable connecting device is a strip structure.

[0015] In the above description, as a preferred embodiment, the strip structure is elastic.

[0016] In the above description, as a preferred embodiment, one end of the detachable connecting device is fixedly connected to the first refrigeration component.

[0017] In the above description, as a preferred embodiment, the first cooling component has a double-layer backpack-shaped structure, consisting of an outer layer and an inner layer. The side closer to the human body is the inner layer, and the side farther from the human body is the outer layer. The inner layer has a mesh structure, and a semiconductor cooling device is installed inside the first cooling component. A fan is installed on the outer layer.

[0018] In the above description, as a preferred embodiment, the second cooling component is a double-layer backpack-shaped structure, consisting of an outer layer and an inner layer. The side closer to the human body is the inner layer, and the side farther from the human body is the outer layer. The inner layer has a mesh structure, and fans are installed on the lower left and right sides of the outer layer. Straps are provided on the outer layer near the fans to bind the waist of the human body.

[0019] The beneficial effects of this invention are as follows: This design achieves large-area cooling of the upper body from front to back while reducing the size requirements of the device, making it universally applicable. Furthermore, it allows for independent use after separation. This expands the application scenarios and provides users with more choices. Attached Figure Description

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] Example 1, a wearable cooling device that can be used in combination (see reference) Figure 1 (2, 3) Includes a first cooling component 1 and a second cooling component 2. The first cooling component 1 and the second cooling component 2 are respectively suspended from the front and back of the upper body of the human body for cooling. The first cooling component 1 and the second cooling component 2 are movably connected by a detachable connecting device 3, which consists of two strip-shaped straps with Velcro. One end of the two straps is sewn to the upper left and right sides of the first cooling component 1, and the other end of the two straps is a free end with Velcro attached. Correspondingly, a fleece surface is provided on the surface of the straps to facilitate the hook and loop fastening of the Velcro. Correspondingly, U-shaped connecting buckles are provided on the upper left and right sides of the second cooling component 2. The free ends of the straps pass through the U-shaped connecting buckles and are glued to the fleece surface using the adhesive function of the Velcro. By combining the upper ends of the first cooling component 1 and the second cooling component 2, the two cooling components are combined. The two straps are respectively suspended on the shoulders of the human body. The length of the straps can be adjusted to accommodate different sizes and achieve a comfortable fit.

[0041] To further stabilize the first cooling component 1 and the second cooling component 2 in relation to the human body restraints, (refer to...) Figure 6A first connecting device 4 and a second connecting device 5 are respectively provided on the left and right sides of the lower end of the first cooling component 1. The first connecting device 4 and the second connecting device 5 are also strip-shaped straps, one end of which is fixedly sewn to the lower left and right sides of the first cooling component 1, and the other end is a free end. One of the two free ends is Velcro, and the other end is made of fleece, facilitating adhesion between the two. (Reference) Figure 2 Corresponding to (3, 7), a third connecting device 6 and a fourth connecting device 7 are also respectively provided on the lower left and right sides of the second cooling component 2. The third connecting device 6 and the fourth connecting device 7 are also strip-shaped straps, one end of which is fixedly sewn to the lower left and right sides of the second cooling component 2, and the other end is a free end. One end of the two free ends is Velcro, and the other end is fleece, facilitating adhesion between them. If the free end of the first connecting device 4 is Velcro, then the corresponding free end of the third connecting device 6 is fleece. If the free end of the second connecting device 5 is fleece, then the free end of the fourth connecting device 7 is Velcro. This allows for movable connections from below between the first connecting device 4 and the second connecting device 5 and the third connecting device 6 and the fourth connecting device 7, respectively, to bind the first cooling component 1 and the second cooling component 2 around the waist of the human body. This ensures that the two cooling components fit snugly against the back and chest of the human body, achieving the purpose of cooling.

[0042] In this implementation, a third connecting device 6 and a fourth connecting device 7, which are strip-shaped straps, are provided on the lower left and right sides of the second refrigeration component 2 to facilitate connection. (Reference) Figure 4 (5, 7, 18) However, another technical solution is that the third connecting device 6 and the fourth connecting device 7 can also be U-shaped connecting buckles. The strap structure of the first connecting device 4 and the second connecting device 5 passes through the U-shaped connecting buckle, and then the Velcro structure is used to achieve the same connection effect.

[0043] The advantages of this design are: it achieves large-area cooling of the human body while adapting to people of different body types, avoiding the drawback of existing air-conditioned clothing requiring multiple sizes. This significantly reduces production and management costs, while also making it more convenient for consumers to use.

[0044] Furthermore, this design has an extended application: the first cooling component 1 can also be used independently. The detachable connecting device 3, without connecting to the second cooling component 2, can hang down independently. The Velcro on the free end of the detachable connecting device 3, in conjunction with the fleece surface, forms a strap hole 11. The first connecting device 4 and the second connecting device 5 then pass through this hole, connecting their free ends and securing them to the waist. This achieves the purpose of independent use. This expands the usage scenarios, allowing for the simultaneous use of the first cooling component 1 and the second cooling component 2, or the use of the first cooling component 1 alone, according to individual needs, thus achieving the goal of flexible use.

[0045] In this embodiment, when the first cooling component 1 is used alone, (refer to...) Figure 13 A through hole needs to be formed by bending the detachable connecting device 3, allowing the first connecting device 4 and the second connecting device 5 to pass through and be secured at the waist. Alternatively, the lower part of the detachable connecting device 3 can be designed as a double-layer structure, thus also achieving the purpose of a through hole, facilitating the passage of the first connecting device 4 and the second connecting device 5. Furthermore, when a double-layer structure is used on the first connecting device 4 and the second connecting device 5, the detachable connecting device 3 can pass through the double-layer structure to achieve connection. Similarly, if the detachable connecting device 3 is fixedly sewn onto the second cooling component 2, the second cooling component 2 can also be used independently.

[0046] In addition to the above-mentioned technical solution of bending the detachable connecting device 3 to form a through hole, a velvet surface can also be provided on the surfaces of the first connecting device 4 and the second connecting device 5, and the Velcro on the detachable connecting device 3 can be directly attached to the first connecting device 4 and the second connecting device 5 to form a movable connection.

[0047] (refer to Figure 14 Alternatively, by setting snaps on the detachable connecting device 3, the first connecting device 4, and the second connecting device 5 respectively, the purpose of movable connection can also be achieved.

[0048] Example 2, (reference) Figure 811) To further expand the application scenarios of this refrigeration device, further optimizations are made based on Embodiment 1. In Embodiment 1, one end of the detachable connecting device 3 is sewn and fixed to the first refrigeration component 1, so that the first refrigeration component 1 can be used independently. In this embodiment, the detachable connecting device 3 is a separate strap with Velcro at both ends and a fleece lining in the middle. The upper left and right sides of the first refrigeration component 1, like the second refrigeration component 2, are provided with U-shaped connecting buckles, so the detachable connecting device 3 can simultaneously connect the first refrigeration component 1 and the second refrigeration component 2 for combined use. It can also be used independently with any one of the refrigeration components, providing users with greater convenience and choice.

[0049] In the two embodiments above, the straps can also be elastic straps, which makes it easier to achieve a good binding effect.

[0050] Furthermore, because the above embodiment uses a combination of Velcro and U-shaped fasteners to achieve a movable connection and dynamic adjustment of tightness, alternatively, a Velcro structure can be omitted. Instead, ordinary woven straps and U-shaped fasteners (commonly found in backpack connections) can be used, achieving the same purpose of a movable connection and dynamic adjustment of tightness.

[0051] Alternatively, buttons and U-shaped fasteners can be used together to achieve movable connections and dynamic adjustment of tightness.

[0052] Alternatively, snap-fit ​​connections can be used at the joints for interlocking (this connection structure is also commonly found on backpack products).

[0053] In the two embodiments described above, (refer to...) Figure 3 6) The first cooling component 1 is a double-layer backpack-shaped structure, divided into an outer layer and an inner layer, with an inner cavity in the middle. The side closer to the human body is the inner layer, and the side farther away from the human body is the outer layer. The inner layer is made of a mesh-like fabric. A semiconductor cooling device is provided in the inner cavity of the first cooling component 1. A fan is installed on the outer layer of the first cooling component 1, and the fan blows air towards the inner layer.

[0054] The semiconductor cooling device 9 is mounted on the inner layer of the first cooling component 1. The temperature-conducting plate 902 on the semiconductor cooling device 9 is exposed on the inner layer, facing the back of the human body, and in direct contact with the back of the human body. (Reference) Figure 15 The housing 905 of the semiconductor cooling device 9 is hidden inside the cavity of the first cooling component 1.

[0055] (refer to Figure 1617) The semiconductor cooling device 9 utilizes the Peltier effect for cooling. It includes a cooling semiconductor 901, a temperature-conducting plate 902, a heat sink 903, a cooling fan 904, and a housing 905. The cooling semiconductor 901 has two functional surfaces, one for heating and the other for cooling. When current drives the cooling semiconductor 901, one surface cools while the other heats. The cooling surface and the temperature-conducting plate 902 are in direct, tight contact, directly conducting the low temperature to the back of the user, providing comfort. The heat sink 903 is tightly attached to the heating surface. The heat sink 903 is typically made of a high-efficiency thermally conductive metal (such as aluminum alloy or copper alloy). The heat sink 903 conducts and dissipates the heat generated by the heating surface of the cooling semiconductor 901 to maintain stable operation. To further improve heat dissipation, a cooling fan 904 is installed on the heat sink 903. The cooling fan 904 generates airflow, quickly removing the heat from the heat sink 903. The cooling semiconductor 901, heat sink 903, and cooling fan 904 are all housed inside the housing 905. The temperature-conducting plate 902 is located on the outside of the housing 905, with a gap between it and the housing 905. A through-hole is provided on the inner layer for the temperature-conducting plate 902 to pass through. The edge of the through-hole engages with the gap between the temperature-conducting plate 902 and the housing 905, allowing the entire cooling device 9 to be fixed to the inner layer of the first cooling assembly 1. A strap with Velcro is used for further detachable securing of the cooling device 9. The through-hole on the housing 905 facilitates air entry and exit.

[0056] A storage bag is provided inside the inner cavity of the first cooling component 1, located near the outer layer, for holding a power bank. An electronic control switch 10 is located on the outer layer. The power bank provides power to the fan 8 and the semiconductor cooling device 9, and the electronic control switch 10 controls the fan 8 and the semiconductor cooling device 9 to turn on or off. Conductive wires connect the electronic control switch 10 to the power bank, and the fan 8 and the semiconductor cooling device 9 electrically.

[0057] (refer to Figure 12Additionally, the fan 8 consists of a fan body 801 and a locking part 802, which are engaged by snap-fit ​​mechanisms. The fan body 801 and the locking part 802 are respectively located on the inner and outer sides of a through hole in the outer layer. During installation, the outer fabric layer is clamped by the snap-fit ​​mechanism, fixing the fan 8 to the upper outer side of the first cooling component 1. Similarly, the fan body 801 and the locking part 802 can be detachably connected by screws. A third method is to use a threaded connection between the locking part 802 and the fan body 801 for assembly and disassembly, replacing the corresponding snap-fit ​​mechanisms with internal and external threads, and engaging the locking part 802 and the fan body 801 by rotation. This detachable structure has two advantages over the integrated connection of the fan 8 and the first cooling component 1: firstly, it facilitates repair and replacement in case of electrical faults during production, thus reducing production costs. Secondly, it facilitates subsequent cleaning of the backpack. When cleaning the backpack, electronic components such as the fan 8, cooling device 9, and power bank can be directly removed from the backpack, so that the backpack itself can be washed directly with water.

[0058] (refer to Figure 7 (10, 11) In the above embodiments, the second cooling component 2 also has a double-layer backpack-shaped structure, consisting of an outer layer and an inner layer. The side closer to the human body is the inner layer, and the side farther from the human body is the outer layer. The inner layer has a mesh structure, and fans are installed on the lower left and right sides of the outer layer. Straps are added to the outer layer near the fans to bind the waist of the human body. These straps achieve better binding based on the third connecting device 6 and the fourth connecting device 7. (Reference) Figure 7 Another use of the strap is that when the third connecting device 6 and the fourth connecting device 7 are U-shaped or H-shaped connecting buckles, the strap can be directly connected to the separable connecting device 3, thus replacing the third connecting device 6 and the fourth connecting device 7, and being equivalent to the third connecting device 6 and the fourth connecting device 7, thereby achieving the purpose of using the second refrigeration component 2 independently.

[0059] The structure and installation method of this fan are the same as those of the fan on the first cooling assembly 1, and will not be described in detail here. Inside the second cooling assembly 2, near the outer layer, there is a storage bag for holding a power bank. An electronic control switch 10 is also located on the outer layer. The power bank provides power to the fan 8, and the electronic control switch 10 controls the fan 8 to turn on or off. The electronic control switch 10, the power bank, and the fan 8 are electrically connected by conductive wires. Additionally, a waterproof bag is added inside the second cooling assembly 2, located near the inner layer. Ice packs can be placed inside the waterproof bag to increase comfort in high-temperature environments, and the airflow driven by the two fans 8 will deliver the low temperature of the ice packs to other areas of the chest.

[0060] When using the combinable wearable cooling device, the fan 8 and cooling device 9 are installed on the first cooling component 1 and electrically connected to the power bank and the electronic control switch 10. Similarly, the new fan 8 is installed on the second cooling component 2, and a separate power bank and ice pack are inserted. The power bank and electronic control switch 10 within the second cooling component 2 are then electrically connected. After installing the relevant electronic components, the first cooling component 1 and the second cooling component 2 are connected using the separation connection device 3 and worn on the body. The first connecting device 4, the second connecting device 5, the third connecting device 6, and the fourth connecting device 7 are then used to secure the two cooling components and the waist of the body, achieving fixation. After turning on the electronic control switch 10 on each cooling component to connect the power, the cooling device 9 begins cooling, directly cooling the back area through the temperature-conducting plate 902. Simultaneously, fan 8 begins to blow air into the inner cavities of the two cooling components. The air blown by fan 8 on the first cooling component 1 forms an airflow that carries away heat from the back of the body as it passes through the mesh. This also provides more fresh air to the cooling fan 904 of the semiconductor cooling device 9, accelerating the expulsion of heat generated by the cooling device 9 through the mesh on both sides of the backpack body 1. Simultaneously, the air blown by fan 8 also diffuses the coolness generated by the heat-conducting plate in all directions, thus making the entire back feel cool. Then, the electronic control switch 10 on the second cooling component 2 is turned on. The two fans 8 below the second cooling component 2 also blow air into the inner cavity of the second cooling component 2. The air blown by fan 8 forms an airflow that carries away heat from the chest of the body as it passes through the mesh, while also diffusing the cool air around the ice pack to other parts of the body. This achieves the goal of simultaneously dissipating heat from the front and back of the upper body.

[0061] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
