These functional eye masks typically use a thermoelectric cooler as a heat exchange structure, utilizing the cold end of the thermoelectric cooler to cool the face mask. In related technologies, after transferring heat from the face mask to the hot end of the thermoelectric cooler, a cooling fan is usually used to dissipate heat from the hot end. This cooling method is not only inefficient and ineffective but also produces significant aerodynamic noise. Summary of the Invention

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 scope of protection of the present utility model.

[0038] Wearable devices, such as functional eye masks with cooling functions, can be worn on the user's head and apply a cooling compress to the face around the eye sockets using a face mask. These functional eye masks typically use a thermoelectric cooler as a heat exchange structure, utilizing the cold end of the thermoelectric cooler to cool the face mask. In related technologies, after transferring heat from the face mask to the hot end of the thermoelectric cooler, a cooling fan is usually used to dissipate heat from the hot end. This cooling method is not only inefficient and ineffective but also produces significant aerodynamic noise.

[0039] In view of this, the present invention proposes a wearable device that can improve the heat dissipation efficiency of the hot end of a semiconductor cooler and reduce the operating noise of the device.

[0040] Please refer to Figures 1 and 2, where the arrows in Figure 2 indicate the direction of liquid flow. In one embodiment of this utility model, the wearable device includes a device body 100 and a heat exchange structure. The heat exchange structure can exchange heat with the device body 100 to achieve cooling or heating of the device body 100, thereby allowing the temperature of some or all of the structure of the device body 100 to decrease or increase.

[0041] Optionally, the heat exchange structure includes a thermoelectric cooler 210. The thermoelectric cooler 210 is also called a thermoelectric cooler. The thermoelectric cooler 210 has two working ends that can transfer heat to each other. The working end that absorbs heat from the outside is called the cold end, and the working end that releases heat to the outside is called the hot end. The heat from the cold end can be transferred to the hot end.

[0042] Specifically, please refer to Figure 2. The two working ends of the semiconductor cooler 210 are defined as the first working end 211 and the second working end 212. The first working end 211 exchanges heat with the first circulation path 220, and the second working end 212 exchanges heat with the device body 100.

[0043] Without loss of generality, the cold and hot ends of the semiconductor cooler 210 can be interchanged by reversing the direction of the current. For example, when a forward current is applied, the second working end 212 is the cold end, and when a reverse current is applied, the second working end 212 becomes the hot end, thereby enabling the switching between cooling and heating modes. It can be understood that when the second working end 212 is the cold end, the device body 100 can be cooled and cooled; when the second working end 212 is the hot end, the device body 100 can be heated and heated.

[0044] Referring to Figure 2, in one embodiment, the heat exchange structure further includes a first circulation path 220, which is provided with a liquid storage tank 221 for liquid circulation. Specifically, the liquid storage tank 221 stores a large amount of liquid, which can participate in the circulation of liquid within the first circulation path 220, thereby improving the heat exchange efficiency between the first working end 211 of the thermoelectric cooler 210 and the liquid within the first circulation path 220.

[0045] For example, when the second working end 212 is the cold end and the first working end 211 is the hot end, the liquid circulating in the first circulation path 220 can quickly remove the heat from the first working end 211 (i.e. the hot end), thereby improving the heat dissipation efficiency and effect on the hot end, and thus enabling the main body of the equipment 100 to cool and cool down more quickly, and enabling the main body of the equipment 100 to be maintained at a low temperature more stably.

[0046] In other words, when the main body of the device 100 needs to be cooled, the present invention can liquid cool the hot end of the semiconductor cooler 210. Compared with the technology of only air cooling the hot end through the cooling fan, it can improve the heat dissipation efficiency of the hot end of the semiconductor cooler 210, thereby improving the cooling efficiency and effect of the main body of the device 100. At the same time, it can also avoid the aerodynamic noise of the cooling fan, thereby reducing the operating noise of the device.

[0047] Referring to Figure 1, in one embodiment, optionally, the device body 100 includes an eye mask, which includes a housing 101 and a face mask 102 disposed on the housing 101. The face mask 102 is capable of exchanging heat with the second working end 212. The face mask 102 is able to at least contact the facial skin around the eye sockets and, under the action of the semiconductor cooler 210, achieve a cold or hot compress effect on the eyes and surrounding area. Optionally, the eye mask may also have a massage function, such as pneumatic massage or mechanical massage using a massage head.

[0048] It should be noted that the application scenarios of this utility model are not limited to goggles, but can also be applied to head-mounted display devices such as VR glasses, or to smart sportswear and smart vests worn on the body that have functions such as monitoring heart rate, body temperature, or muscle activity. The heat exchange function of the semiconductor cooler 210 is not limited to realizing the cold or hot compress function of the goggles, but can also be used to dissipate heat from heat-generating components, such as the imaging module and / or control chip of AR glasses or VR glasses, which are prone to heat generation.

[0049] Referring to Figure 2, in one embodiment, the heat exchange structure optionally includes a second circulation path 230 for supplying liquid circulation. The second circulation path 230 has a first heat exchange section 231 and a second heat exchange section 232 connected to each other. The first heat exchange section 231 is disposed on the device body 100, and the second heat exchange section 232 is disposed on the second working end 212. That is, in this embodiment, the second working end 212 and the device body 100 do not undergo direct heat exchange, but rather undergo indirect heat exchange through the liquid in the second circulation path 230. In this way, the liquid circulating in the second circulation path 230 can improve the efficiency and effect of cooling or heating the device body 100. Of course, in other embodiments, the second circulation path 230 may not be provided, and the second working end 212 may directly abut against the device body 100, or indirectly abut against the device body 100 through thermal grease or the like, to achieve direct heat exchange between the second working end 212 and the device body 100.

[0050] It is understood that the first circulation path 220 and the second circulation path 230 constitute an independent dual circulation path, which enables both working ends of the semiconductor cooler 210 to obtain good and efficient heat exchange, improves the operational stability of the entire heat exchange structure, and enhances the cooling or heating effect of the main body of the equipment 100.

[0051] Optionally, in embodiments where the device body 100 includes an eye mask, the first heat exchange section 231 is in contact with the face mask 102 and transfers heat. Thus, the first heat exchange section 231 can directly exchange heat with the face mask 102, thereby improving the cooling or heating rate and effect of the face mask 102. Of course, in other embodiments, the first heat exchange section 231 and the face mask 102 can also achieve indirect heat exchange through other heat transfer structures.

[0052] Optionally, the device body 100 includes a housing and a flexible bag disposed within the housing, the flexible bag being configured as a first heat exchange part 231. Optionally, the flexible bag can be made of elastic and flexible materials such as silicone or rubber, for example, referencing the silicone water bags used by long-distance runners. Thus, in embodiments where the device body 100 includes an eye mask, using a flexible bag as the first heat exchange part 231 improves the fit between the flexible bag and the face mask 102, thereby enhancing the heat exchange efficiency and effect between the two, and also allows the face mask 102 to better fit the face, preventing the user's face from being bumped by protruding foreign objects. Of course, in other embodiments, the flexible bag may not be provided, and the first heat exchange part 231 may be directly formed on the housing; alternatively, the device body 100 may include a separately formed housing and a heat exchange chamber, with the heat exchange chamber configured as the first heat exchange part 231.

[0053] Referring to Figure 2, optionally, the top of the flexible bag is provided with a vent 104, which allows air to be expelled from the second circulation path 230, thereby improving the smoothness of liquid flow in the second circulation path 230. Furthermore, a one-way valve (not shown in the figure) can be provided on the vent 104 to restrict outside air from entering the flexible bag through the vent 104.

[0054] Optionally, the specific heat capacity of the liquid in the first circulation path 220 is greater than that of the liquid in the second circulation path 230. That is, the medium in the second circulation path 230 is replaced with a liquid with a lower specific heat capacity, and the medium in the first circulation path 220 is replaced with a liquid with a higher specific heat capacity. This allows the temperature of the device body 100 to rise or fall more rapidly. Of course, in other embodiments, the specific heat capacity of the liquid in the first circulation path may be less than or equal to that of the liquid in the second circulation path 230.

[0055] Optionally, the liquid in the second circulation path 230 is configured as an aqueous solution of glycerol or ethylene glycol, and the liquid in the first circulation path 220 is configured as water. This results in a simple and easy-to-implement structure. It is worth noting that in the embodiment where the storage tank 221 is detachable and the liquid in the first circulation path 220 is replaceable, since water is used as the heat exchange medium in the first circulation path 220, users can easily replace the water in the storage tank 221 as needed. For example, tap water can be directly poured into the storage tank 221, without requiring the user to prepare a special liquid as the heat exchange medium for the first circulation path 220.

[0056] Referring to Figure 2, in one embodiment, optionally, the first heat exchange section 231 and the second heat exchange section 232 are separately arranged. The second circulation path 230 further includes two connecting pipes 233. The liquid inlet of the first heat exchange section 231 is connected to the liquid outlet of the second heat exchange section 232 through one connecting pipe 233, and the liquid outlet of the first heat exchange section 231 is connected to the liquid inlet of the second heat exchange section 232 through the other connecting pipe 233. Thus, by using two connecting pipes 233 to connect the first heat exchange section 231 and the second heat exchange section 232, the second heat exchange section 232 and the thermoelectric cooler 210 are allowed to be kept away from the first heat exchange section 231 and the device body 100, thereby reducing the impact of the operating noise of the thermoelectric cooler 210 on the device body 100, or reducing the level of operating noise of the thermoelectric cooler 210 perceived by the user. For example, when the device body 100 is an eye mask, if the thermoelectric cooler 210 is directly mounted on or near the eye mask, the operating noise of the thermoelectric cooler 210 can easily propagate into the user's ears. Of course, in other embodiments, the connecting pipe 233 may not be provided, and the first heat exchange section 231 and the second heat exchange section 232 may be directly connected.

[0057] Referring to Figures 1 and 2, in one embodiment, the wearable device may optionally include a handle 300 that is separately disposed from the device body 100. A semiconductor cooler 210, a second heat exchange section 232, and a first circulation path 220 are disposed on the handle 300, and the connecting pipe 233 is configured as a flexible hose. Thus, by utilizing the flexible connecting pipe 233, the handle 300 is allowed to move relative to the device body 100 to adjust their relative positional relationship, thereby making it more convenient for the user to use the handle 300 when wearing the device body 100.

[0058] Please refer to Figure 4. Optionally, in this embodiment, the handle 300 has a mounting cavity 301. The wearable device also includes a control circuit board 400 and a battery 500. The control circuit board 400 is electrically connected to the device body 100, the battery 500, and the thermoelectric cooler 210. The control circuit board 400, the battery 500, the thermoelectric cooler 210, and the second heat exchange unit 232 are disposed in the mounting cavity 301. That is, in this embodiment, the control circuit board 400 for controlling the device body 100 and the battery 500 for supplying power to the device body 100 are both mounted on the handle 300, which simplifies the structure of the device body 100 and reduces its size and volume. Of course, in other embodiments, at least one of the control circuit board 400 and the battery 500 may be disposed on the device body 100.

[0059] It is worth mentioning that, in this embodiment, by independently setting most of the heat exchange structure outside the device body 100, the structure of the device body 100 can be simplified, and the size and volume of the device body 100 can be reduced. This is beneficial for the miniaturization and lightweight design of the device body 100, thereby improving the wearing comfort of the wearable device. Secondly, in the embodiment where the device body 100 is configured as an eye mask with a face mask 102, the heat exchange structure is less susceptible to interference from other factors during operation, thereby making the temperature of the face mask 102 more stable. That is, the face mask 102 can apply cold or hot compresses to the face at a more stable temperature.

[0060] Referring to Figures 1 and 2, in one embodiment, optionally, the two connecting tubes 233 extend from the same side wall of the device body 100. For example, in the illustrated embodiment, the two connecting tubes 233 are connected to opposite ends of the flexible bag and both extend from the right side wall of the goggles, with the exposed portions of the two connecting tubes 233 connected as one unit. This reduces the risk of the connecting tubes 233 interfering with the normal wearing and use of the device body 100, thereby improving the ease of use and flexibility of the wearable device. Of course, in other embodiments, the two connecting tubes 233 may extend from different side walls of the device body 100.

[0061] Optionally, the two connecting pipes 233 extend side by side, and the exposed portions are protected by a protective hose 600, or are bundled together by means of tape wrapping. Of course, in other embodiments, the two connecting pipes 233 may also be mutually constrained and extend in the same direction in the form of a larger pipe enclosing a smaller pipe.

[0062] It is worth mentioning that in embodiments where the handle 300 also includes a control circuit board 400 and a battery 500, the exposed portions of the two connecting tubes 233 and the conductive wires can be covered by the same protective flexible tube 600, thereby avoiding the problem of messy wires and pipes. Of course, in other embodiments, the exposed portions of the two connecting tubes 233 and the conductive wires can also be bound together by means of wrapping with tape or other methods.

[0063] Referring to Figures 2 and 4, in one embodiment, optionally, the first circulation path 220 further includes a first liquid passing tank 225 connected to the liquid storage tank 221. The first liquid passing tank 225 is fitted to the first working end 211, and the second heat exchange section 232 is configured as a second liquid passing tank, which is fitted to the second working end 212. That is, when the liquid in the first circulation path 220 flows through the first liquid passing tank 225, it exchanges heat with the first working end 211 of the thermoelectric cooler 210, and when the liquid in the second circulation path 230 flows through the second liquid passing tank, it exchanges heat with the second working end 212 of the thermoelectric cooler 210.

[0064] It should be noted that the "adhesive setting" and "adhesive contact" described in the embodiments of this utility model refer to a connection method in which two parts are attached surface-to-surface, including the case where the sides of the two parts with the largest or largest surface area are attached surface-to-surface. For example, the side with the largest or largest surface area of ​​the first liquid tank 225 is attached surface-to-surface with the side with the largest or largest surface area of ​​the first working end 211. Based on this, the two sides can be bonded together with adhesive, or they can simply abut against each other without adhesion; this application does not specifically limit this.

[0065] Thus, by setting up a first liquid tank 225 and a second liquid tank, and defining their surface-to-surface connection, the heat exchange area between the dual circulation path and the semiconductor cooler 210 can be increased, thereby improving heat exchange efficiency. Furthermore, the structure is simple and easy to implement. Alternatively, in other embodiments, the first liquid tank 225 and the second liquid tank may not be provided. The first circulation path 220 may also include a first heat exchange tube connected to the liquid storage tank 221. The first heat exchange tube includes multiple continuously bent and interconnected first pipe segments, and is located at the first working end 211. Or, the second heat exchange section 232 may be configured as a second heat exchange tube, which includes multiple continuously bent and interconnected second pipe segments, and is located at the second working end 212.

[0066] Optionally, the heat exchange structure also includes a handle 300 with a mounting cavity 301, in which the first liquid tank 225, the second liquid tank, the thermoelectric cooler 210, and the control circuit board 400 are disposed. Thus, by housing the first liquid tank 225, the second liquid tank, and the thermoelectric cooler 210 within the handle 300, the risk of external environmental interference with the heat exchange between these three components is reduced.

[0067] Referring to Figure 4, in one embodiment, optionally, the first circulation path 220 further includes a liquid guiding channel 310 disposed on the handle 300, the liquid storage tank 221 is provided with a liquid storage cavity 222, and the first liquid passing tank 225 is connected to the liquid storage cavity 222 through the liquid guiding channel 310. In this way, the handle itself constructs a connecting structure connecting the first liquid passing tank 225 and the liquid storage cavity 222, which helps to simplify the structure and installation steps of the first circulation path 220. Of course, in other embodiments, the liquid guiding channel 310 may not be provided; for example, a connecting conduit passing through the handle may be added, with one end of the connecting conduit connected to the first liquid passing tank 225 and the other end connected to the liquid storage cavity 222.

[0068] Without loss of generality, based on the working principle of the semiconductor cooler 210, after continuous or repeated operation, the liquid temperatures in the second circulation path 230 and the first circulation path 220 will tend to be consistent, thereby causing the cooling or heating function to fail. To address this problem, the liquid storage tank 221 may optionally be provided with a liquid outlet 223 communicating with the liquid storage chamber 222. The liquid outlet 223 may be in an exposed, open state or in a blocked, closed state. Specifically, when the heat exchange structure is working normally, the liquid outlet 223 is in a closed state to prevent the liquid in the first circulation path 220 from accidentally flowing out of the liquid outlet 223. When it is necessary to replace the liquid in the storage tank 221, for example, when the liquid temperature in the second circulation path 230 and the first circulation path 220 is close to the same, the user can switch the liquid outlet 223 to the open state to pour out the higher temperature liquid in the first circulation path 220 from the liquid outlet 223 and refill the storage tank 221 with a lower temperature liquid, such as room temperature tap water, from the liquid outlet 223, so that the cooling and heating efficiency of the entire product can be restored to the optimal state.

[0069] Optionally, the handle 300 can be detachably installed on the liquid outlet 223 to either block or expose the liquid outlet 223. That is, the liquid storage tank 221 has an opening at one end to form the liquid outlet 223, and the end wall of the handle 300 is reused as the cover of the liquid storage tank 221. Specifically, when the handle 300 is installed on the liquid outlet 223, the liquid outlet 223 can be closed, thereby forming a sealed structure in the first circulation path 220; the liquid storage tank 221 can be detached from the handle 300, exposing the liquid outlet 223 after detachment, i.e., allowing the liquid outlet 223 to enter a conductive state. Thus, the liquid storage tank 221 does not need to be a closed structure, simplifying its structure and manufacturing process. Secondly, the liquid storage tank 221 in the first circulation path 220 is designed to be easily disassembled. When the liquid temperatures in the second circulation path 230 and the first circulation path 220 are close to the same, the user can remove the liquid storage tank 221 to pour out the higher-temperature liquid in the first circulation path 220 through the liquid outlet 223 and refill the liquid storage tank 221 with a lower-temperature liquid, such as room-temperature tap water, thereby restoring the cooling and heating efficiency of the entire product to its optimal state. Of course, in other embodiments, the handle 300 can be fixed to the liquid outlet 223, or the liquid outlet 223 can be located on the side wall or the end wall away from the handle of the liquid storage tank 221 and is movably sealed with an elastic cap; or the liquid storage tank 221 can be a closed box structure and connected to the first liquid outlet 225 through a connecting conduit passing through the handle 300.

[0070] It is understood that in the illustrated embodiment, the liquid reservoir 221 can serve as an extension of the handle 300, which can increase the surface area and length dimensions available for the user to hold when the two are used as a whole, thereby improving the grip comfort.

[0071] Referring to Figures 3 and 4, in one embodiment, optionally, one of the handle 300 and the liquid reservoir 221 has a locking protrusion 224, and the other has a locking groove 302, with the locking protrusion 224 rotatably engaging with the locking groove 302. This results in a simple structure that is easy to install. Optionally, in this embodiment, a sealing ring 320 is also sandwiched between the handle 300 and the liquid reservoir 221 to improve the sealing between them. Of course, in other embodiments, the handle 300 and the liquid reservoir 221 can be connected by a threaded structure, or they can be directly bonded together, or they can be connected by fasteners such as screws or rivets.

[0072] Referring to Figures 2 and 4, in the embodiment where the control circuit board 400 and battery 500 are located in the mounting cavity 301, optionally, both the battery 500 and the control circuit board 400 are located on the side of the second liquid tank away from the thermoelectric cooler 210. Thus, by placing both the battery 500 and the control circuit board 400 on the side of the second liquid tank away from the thermoelectric cooler 210, when the second working end 212 is the cold end, the second liquid tank cools down after heat exchange with the cold end. Since the control circuit board 400 and battery 500 are close to the second liquid tank, they can also achieve a certain degree of heat dissipation, thereby improving the operational stability of the control circuit board 400 and battery 500.

[0073] Referring to Figure 2, the first circulation path 220 further includes a first liquid pump 226 connecting the liquid storage tank 221 and the first liquid transfer tank 225, and the second circulation path 230 further includes a second liquid pump 234 connecting the first heat exchange section 231 and the second liquid transfer tank. The first liquid pump 226 and the second liquid pump 234 are disposed in the mounting cavity 301. Thus, the first liquid pump 226 and the second liquid pump 234 are used to achieve liquid circulation within the first circulation path 220 and the second circulation path 230, resulting in a simple and easy-to-implement structure. Furthermore, installing both within the mounting cavity 301 simplifies the structure of the wearable device. Of course, in other embodiments, the first liquid pump 226 and the second liquid pump 234 may not be disposed within the mounting cavity 301.

[0074] Referring to Figure 4, both the first liquid pump 226 and the second liquid pump 234 are located on the side of the first liquid tank 225 away from the thermoelectric cooler 210. Thus, by concentrating the first liquid pump 226 and the second liquid pump 234 within the mounting cavity 301, the compactness of the internal components of the handle 300 is improved, thereby reducing the volume and size of the handle 300. Of course, in other embodiments, the first liquid pump 226 and the second liquid pump 234 may both be located on the side of the second liquid tank away from the thermoelectric cooler 210, or the first liquid pump 226 and the second liquid pump 234 may be located on opposite sides of the thermoelectric cooler 210.

[0075] In an embodiment where the handle 300 is provided with a liquid guiding channel 310, optionally, as shown in Figures 2 to 4, the liquid guiding channel 310 includes an outlet channel 311 and a return channel 312. The outlet channel 311 is connected to the inlet end of the first liquid tank 225, and the return channel 312 is connected to the outlet end of the first liquid tank 225. The first circulation path 220 also includes an extension conduit 227, which is connected to the outlet channel 311 and extends from the outlet channel 311 toward the bottom of the storage tank 221. Specifically, the outlet channel 311 is connected between the storage chamber 222 and the inlet end of the first liquid pump 226, and the return channel 312 is connected between the storage chamber 222 and the outlet end of the first liquid tank 225. Thus, the extension conduit 227 has a large gap between its opening near the bottom of the storage tank 221 and the outlet of the return channel 312, which facilitates the circulation of liquid within the storage tank 221 and prevents liquid flowing directly out of the return channel 312 from being sucked away by the outlet channel 311, thereby improving the heat exchange effect. Of course, in other embodiments, the extension conduit 227 can also be installed on the return channel 312.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
