Description

Technical Field

[0001] This utility model relates to the field of temperature control device technology, and in particular to a temperature conducting element and a portable temperature control device. Background Technology

[0002] With the continuous advancement of technology, the demand for portable temperature-regulating devices is increasing in the market. In recent years, to meet people's needs for temperature-regulating devices during outdoor activities or other daily life scenarios, various types of portable fans, such as neck fans, have appeared on the market. Existing portable temperature-regulating devices typically include a temperature-regulating component and a temperature-conducting component. The temperature-regulating component generates cold or heat energy, while the temperature-conducting component transfers the cold or heat energy generated by the temperature-regulating component to the human body, thereby creating a cooling or warming effect. Usually, for the sake of product appearance and easy identification, markings are formed on the surface of the temperature-conducting component, generally through spray painting. This method is relatively expensive, and the markings are rather simple. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figure 1 , Figure 2 and Figure 3 This utility model embodiment provides a portable temperature regulating device 10 and a temperature conducting element 200. The portable temperature regulating device 10 may include, for example, a housing 100, a temperature regulating element 400, and a temperature conducting element 200. The portable temperature regulating device 10 provided in this embodiment may be, for example, a handheld temperature regulating device, a neck-mounted temperature regulating device, a waist-mounted temperature regulating device, or a head-mounted temperature regulating device. The following description uses a neck-mounted temperature regulating device as an example.

[0024] The housing 100 may, for example, have a wearing space 11, through which the housing 100 is worn around the user's neck. A temperature regulating element 400 is disposed within the housing 100 and is used to generate heat or cold energy, i.e., for heating or cooling. The temperature regulating element 400 may, for example, be a semiconductor cooling element, but this embodiment is not limited thereto. A temperature conducting element 200 is disposed on the housing 100 and is exposed on the surface of the housing 100, specifically near the surface of the wearing space 11. The temperature conducting element 200 is thermally connected to the temperature regulating element 400, thereby conducting the heat or cold generated by the temperature regulating element 400 to the human body to achieve the effect of heating or cooling.

[0025] See Figure 4The temperature-conducting component 200 provided in this embodiment of the present invention may include, for example, a temperature-conducting substrate 210 and a printed layer 220. The temperature-conducting substrate 210 may include, for example, an inner surface 21 and an outer surface 22, with the outer surface 22 being, for example, the side of the temperature-conducting component 200 closest to the wearing space 11. The printed layer 220 is disposed on the outer surface 22, and the printed layer 220 includes an identification layer 221 and a thermochromic layer 222. The identification layer 221 is disposed between the outer surface 22 and the thermochromic layer 222, that is, the identification layer 221 is disposed on the outer surface 22, and the thermochromic layer 222 is disposed on the identification layer 221. The identification layer 221 can be, for example, a logo, a pattern, or text. The thermochromic layer 222 covers the identification layer 221. The shape and size of the thermochromic layer 222 can be, for example, the same as the identification layer 221. That is, the thermochromic layer 222 and the identification layer 221 can be, for example, the same logo, pattern, or text. Of course, this embodiment is not limited to this.

[0026] In this embodiment, the printed layer 220 is formed by a printing process. A marking layer 221 is printed on the outer surface 22 of the thermally conductive substrate 210, and then a thermochromic layer 222 is printed on the marking layer 221. Specifically, it can be formed using processes such as printing, decal application, water transfer printing, or heat transfer printing. The marking layer 221 can be, for example, orange paint, and the thermochromic layer 222 can be, for example, blue paint. At low temperatures, the thermochromic layer 222 displays its original color, for example, blue, and the marking layer 221 is covered by the thermochromic layer 222. At high temperatures, the thermochromic layer 222 becomes transparent, allowing the color of the marking layer 221 to show through, thus displaying the color of the marking layer 221, for example, orange. Here, "low temperature" can be, for example, below the color-changing temperature, and "high temperature" can be, for example, above the color-changing temperature.

[0027] The temperature-conducting component 200 provided in this embodiment has a printed layer 220 on the outer surface 22 of the temperature-conducting substrate 210. By setting the printed layer 220 as an identification layer 221 and a thermochromic layer 222, the identification can change color with temperature, thereby improving the aesthetics of the identification. Furthermore, the printed layer 220 is implemented by a printing process, which is simple and can greatly reduce costs compared to the existing painting process.

[0028] See Figure 5The heat-conducting component 200 may also include, for example, a clear varnish layer 230, which covers the side of the printed layer 220 away from the heat-conducting substrate 210. The clear varnish layer 230 may be formed, for example, by spraying. The clear varnish layer 230 may be, for example, a UV varnish, i.e., an ultraviolet-curing varnish, a coating that can be rapidly cured under ultraviolet light. UV varnish cures within seconds under ultraviolet light, greatly improving production efficiency; UV varnish does not contain volatile organic compounds (VOCs), meeting environmental protection requirements; the cured UV varnish film has high hardness and good wear resistance; UV varnish has high transparency, good gloss, and good chemical corrosion resistance; the UV curing process does not require high temperatures, making it more energy-efficient compared to traditional thermal curing. By covering the printed layer 220 with the clear varnish layer 230, the printed layer 220 can be protected, and the surface gloss of the heat-conducting component 200 can be increased. It can also improve the corrosion resistance and wear resistance of the heat-conducting component 200, and make the surface of the heat-conducting component 200 smooth, providing a good tactile experience and improving the user experience.

[0029] See Figure 6 The temperature-conducting component 200 may also include, for example, an adhesion reinforcement layer 240 disposed between the thermochromic layer 222 and the clear coat layer 230. The adhesion reinforcement layer 240 may be made of, for example, acrylic resin and is formed on the surface of the printed layer 220 by a spraying process. The adhesion reinforcement layer 240 enhances adhesion, facilitating the formation of the clear coat layer 230 and ensuring that the clear coat layer 230 adheres firmly and tightly to the temperature-conducting component 200.

[0030] See Figure 7 The temperature-conducting component 200 also includes an appearance layer 250, which covers the outer surface 22 of the temperature-conducting substrate 210. A printed layer 220 is disposed on the side of the appearance layer 250 away from the temperature-conducting substrate 210. The appearance layer 250 can be formed, for example, by spraying black paint, thus making the appearance layer 250 black. The appearance layer 250 can, for example, cover the entire outer surface 22 of the temperature-conducting substrate 210, thereby giving the temperature-conducting substrate 210 an aesthetically pleasing appearance to match the product appearance of the portable temperature-regulating device 10 and improve its aesthetics. Of course, the color of the appearance layer 250 can also be, for example, other colors; this embodiment is not limited to this.

[0031] Further, see Figure 8 The printing layer 220 also includes a base color layer 223, which is disposed between the identification layer 221 and the appearance layer 250. In this embodiment, the base color layer 223 can be formed, for example, by printing with colored paint. The base color layer 223 can be, for example, white, or of other colors. The base color layer 223 can prevent color mixing between the appearance layer 250 and the identification layer 221, further improving the aesthetics of the identification.

[0032] In one embodiment of this invention, the thermally conductive substrate 210 may be, for example, a metal part, specifically, an aluminum alloy part. The outer surface 22 of the metal part may also have an oxide layer, and a printed layer 220 is disposed on the oxide layer. The thermally conductive substrate 210 may form the oxide layer, for example, through whitening and passivation. Whitening the provided thermally conductive substrate 210 can remove impurities from its surface, ensuring that the surface of the thermally conductive substrate 210 is free of dust, oxide layers, oil stains, and other impurities. Passivating the whitened thermally conductive substrate 210 forms a passivation layer on its surface. This passivation layer is a dense oxide layer that can firmly and tightly adhere to the surface of the thermally conductive substrate 210, thus protecting the thermally conductive substrate 210 and reducing its surface roughness.

[0033] In one embodiment of this invention, the thickness of the marking layer 221 is 5 ± 1 micrometer, the thickness of the thermochromic layer 222 is 10 ± 1 micrometer, the thickness of the base color layer 223 is 5 ± 1 micrometer, the thickness of the clear varnish layer 230 is 25 ± 2 micrometers, and the thickness of the adhesion reinforcement layer 240 is 5 ± 1 micrometer. Of course, this embodiment is not limited to these dimensions and can be configured according to actual needs.

[0034] See also Figure 1 and Figure 2 The portable temperature control device 10 may, for example, also include a fan 310 and a heat sink 320. The housing 100 is provided with an air inlet 101 and an air outlet 102. The housing 100 may, for example, include a first housing 110 and a second housing 120, which are connected and form an installation space between them. The fan 310, heat sink 320, and temperature control device 400 are all disposed within this installation space. The heat sink 320 and fan 310 can be used to help the temperature control device 400 dissipate heat, and the fan 310 can also blow air out through the air outlet 102 for cooling. Of course, the portable temperature control device 10 may also include necessary components such as a battery and a circuit board, which will not be described in detail in this embodiment.

[0035] In summary, the temperature-conducting component 200 provided in this embodiment of the present invention achieves temperature-sensitive color-changing of the markings by setting a printing layer 220 on the outer surface 22 of the temperature-conducting substrate 210, and by setting the printing layer 220 as an identification layer 221 and a thermochromic layer 222, thereby improving the aesthetics of the markings. Furthermore, the printing layer 220 is achieved through a printing process, which is simple and significantly reduces costs compared to existing painting processes. The clear varnish layer 230 protects the printing layer 220 and increases the surface gloss of the temperature-conducting component 200, while also improving its corrosion resistance and wear resistance. It also makes the surface of the temperature-conducting component 200 smooth, providing a good tactile experience and enhancing the user experience. The adhesion enhancement layer 240 strengthens adhesion, facilitating the formation of the clear varnish layer 230 and ensuring it adheres firmly and tightly to the temperature-conducting component 200. The appearance layer 250 matches the product appearance of the portable temperature-regulating device 10, improving its aesthetics. The use of a base color layer 223 prevents color mixing between the appearance layer 250 and the labeling layer 221, further enhancing the aesthetics of the labeling. The portable temperature control device 10 provided in this embodiment, through the use of a temperature-conducting component 200, can improve the aesthetics of its labeling, reduce production costs, and enhance the user experience.
