Description

Technical Field

[0001] This invention relates to the field of refrigeration or heating products, specifically to a modular combined cold and heat source device and its usage method. Background Technology

[0002] Existing wearable temperature-controlled clothing used in special industries such as medical care, high-temperature (or low-temperature) operations, outdoor work, and sports mostly uses ice packs, PCM material packages, or heating elements as cold or heat sources, combined with water circulation pipes to achieve wearability. The process is complicated and cumbersome, making it awkward and restricting the body's flexibility and movement, which hinders the promotion and application of the product.

[0003] Currently, common ice packs or cold / heat source devices still have many shortcomings. On the one hand, some existing ice pack products are made by combining or pressing multiple ice pack units into an ice pack sheet at one time. These units are an integral, non-separable structure, making it impossible to flexibly adjust the number and combination of cold or heat source modules according to actual usage needs. Furthermore, the ice pack units themselves lack the form of independent containers, making it difficult to achieve independent replacement and refilling of individual modules. On the other hand, while some ice pack products have water inlets, these inlets often use a one-time tear-off opening structure, which is damaged once opened and cannot be resealed. The bag body and the cold source body are also inseparable, making it impossible to achieve modular replacement and reuse of the ice pack as a whole. In addition, existing ice pack products are mostly of fixed shape and size, making it difficult to adapt to the free bending of different parts of the human body, and they usually have a single carrying method, resulting in deficiencies in terms of convenience and safety. Summary of the Invention

[0004] The purpose of this invention is to provide a modular combined cold and heat source device and its usage method. This combined cold or heat source adopts an ultra-thin or arbitrary shape modular design, which can be used as a single piece or two or more pieces can be combined and placed in a packaged bag for use. The modular combination design can bend freely with the body, and the ultra-thin design meets energy needs while ensuring user comfort. It is convenient to replace during use, can effectively suppress energy loss and prevent leakage of cold or hot liquid, has a higher safety factor, greatly increases the scope of application, and solves the above-mentioned problems existing in the prior art.

[0005] The present invention discloses a modular combined cold and heat source device, comprising a packaging bag and at least one cold or heat source module detachably housed within the packaging bag. The packaging bag is made of elastic plastic film material and has a handle at the top. The cold or heat source module is an ultra-thin module or a module of arbitrary shape, and has a liquid injection sealing port at one corner. The liquid injection sealing port is a resealable sealing port structure. The cold or heat source module can be a single piece, two pieces, or multiple pieces. Multiple cold or heat source modules can be combined to allow for free bending with the body.

[0006] Furthermore, the top of the cold source or heat source module is provided with a lanyard hole, and a lanyard is installed in the lanyard hole.

[0007] Furthermore, a decorative cover plate is provided on the liquid injection sealing port.

[0008] Furthermore, the cold source or heat source module incorporates a latent heat storage constant temperature material or a refrigeration liquid formulated with a polymer compound, which has a high enthalpy temperature storage function; or, the cold source or heat source module incorporates a heating liquid formulated with a latent heat storage constant temperature material or a polymer compound, which has a high enthalpy temperature storage function.

[0009] The present invention also provides a method for using a modular combined cold and heat source device, which includes the following steps: A. Select the quantity and size of cold source or heat source modules according to the cooling or heating requirements. After the selected single or multiple cold source or heat source modules are cooled in a refrigerator or heated in a heating mode, they are placed in a packaging bag in a detachable manner to form a combined cold source group or heat source group. B. Insert the packaging bag together with the internal cold or heat source module into the wearable temperature-controlled clothing, or use the heat-insulating and waterproof bag on the outer cover of the cold or heat source module as a cold or heat source on its own.

[0010] Compared with the prior art, the beneficial technical effects of the present invention are as follows: The modular combined cold and heat source device of this invention adopts an ultra-thin module or arbitrary shape module design, which can be used in single, double or multiple modules according to actual needs. After the modules are combined, they can bend freely with the body, overcoming the defects of existing ice pack products whose fixed shape is difficult to adapt to the bending of the body. It ensures the comfort of use while meeting the cooling or heating needs. At the same time, the cold or heat source module is detachably housed in the packaging bag, which is convenient to replace during use and supports independent replacement and reuse of modules. This overcomes the defects of existing ice pack units that cannot be separated, resulting in inflexible adjustment. Furthermore, the packaging bag, together with the resealable liquid injection port set at the corner of the module, forms a reliable sealing structure, which can effectively suppress energy loss and prevent cold or hot liquid leakage. This overcomes the defects of existing water injection ports that use one-time tear-type opening lines, which make them unable to be resealed and used, resulting in a higher safety factor.

[0011] This invention can be applied not only to wearable temperature-controlled clothing, but also as an independent cold or heat source for various scenarios such as local cold or hot compresses and outdoor work, greatly increasing its applicability and facilitating its promotion.
