[0060] The cover 114 is detachably combined with the outer cover 113 so as to cover the outer cover 113. The cover 114 is formed in an elliptical curved surface and is formed in substantially the same shape and size as the outer cover 113. The cover 114 completely covers the outer cover 113 and forms an upper portion of an outer appearance. The bottom surface of the cover 114 is in surface contact with the top surface of the outer cover 113. The edge of the cover 114 covers the edge of the outer cover 113, but is not in contact with the edge of the main cover 111.

[0061] The cover 114 is formed with holes matching the holes formed in the outer cover 113 and through which air flowed into the air supply part 130 and air discharged from the air supply part 130 pass. The cover 114 is formed with a hole through which air is flowed in on one side in the long axis direction, and a hole through which air is discharged on the other side.

[0062] The cover 114 is formed of a light-blocking material so as to protect the electrical part 140, the air supply part 130, etc. covered by the outer cover 113 which is a light-transmissive material.

[0063] The cover 114 can be manufactured in various textures or colors so as to be replaced and used according to the preference of a user.

[0078] Figure 7is a partial sectional view of the main body of the wearable device of an embodiment of the present utility model, Figure 8 is a perspective view of the main cover body of the wearable device of an embodiment of the present utility model, Figure 9 is a partial sectional view of the main body of the wearable device of an embodiment of the present utility model, Figure 10 is an exploded perspective view of a part of the wearable device of an embodiment of the present utility model, Figure 11 is a partial sectional view of the main body of the wearable device of an embodiment of the present utility model.

[0079] With reference to Figure 7 , the planar portion P of the plate 123 is formed in the middle, and the curved portions thereof are formed on both sides in the long axis direction. The closer to both ends in the long axis direction from the planar portion P, the more the plate 123 is curved downward. Thus, the plate 123 can be close to the human body, especially the neck.

[0080] The planar portion P of the plate 123 is close to the bottom surface of the thermoelectric element 121. The planar portion P of the plate 123 does not need to be close to the bottom surface of the thermoelectric element 121 as a whole, and preferably, most of the planar portion P of the plate 123 is close to the bottom surface of the thermoelectric element 121. A part of the curved portion of the plate 123 is arranged apart from the bottom surface of the thermoelectric element 121.

[0081] The body temperature adjusting portion 120 can include a heat conducting sheet arranged between the thermoelectric element 121 and the plate 123 and dispersing heat. The heat conducting sheet is preferably a graphite sheet containing a carbon-based material such as carbon or graphite felt, carbon cloth, carbon black, graphite powder, or graphene.

[0082] The body temperature adjusting portion 120 can include a heat conducting grease, which is a viscous material arranged between the thermoelectric element 121 and the plate 123 and transferring heat. The heat conducting grease is preferably arranged between the curved portion of the plate 123 and the bottom surface of the thermoelectric element 121.

[0083] With reference to Figure 8 , the main cover body 111 of an embodiment of the present utility model includes: a main cover body 1111 having an oval bowl shape; and an oval plate seating surface 1112 protruding to the lower side of the main cover body 1111.

[0084] The plate 123 is combined with the plate seating surface 1112. The plate seating surface 1112 can be formed to be almost similar to the shape of the plate 123 to be close to and combined with the plate 123. The plate seating surface 1112 is formed to be oval, in which the middle portion is formed to be planar, and both sides in the long axis direction are formed to be curved.

[0085] An open placement surface opening portion 1112a is formed in a middle portion of the plate placement surface 1112 to expose the bottom surface of the thermoelectric element 121. The placement surface opening portion 1112a is formed larger than the bottom surface of the thermoelectric element 121 so that the bottom surface of the thermoelectric element 121 passes through.

[0086] A placement surface flat portion 1112b is formed in the plate placement surface 1112 so as to be flat in correspondence with the flat portion P of the plate 123. The placement surface flat portion 1112b forms a part of the periphery of the placement surface opening portion 1112a. That is, a part of the placement surface opening portion 1112a is formed in the placement surface flat portion 1112b.

[0087] Referring to Figure 9 The bottom surface of the thermoelectric element 121 protrudes downward by a prescribed height G from the placement surface flat portion 1112b. Thus, even if the plate 123 is in close contact with the plate placement surface 1112, it is in close contact with the bottom surface of the thermoelectric element 121. At least a part of the bottom surface of the main housing 111 is disposed at a position higher than the bottom surface of the thermoelectric element 121.

[0088] At least a part of the bottom surface of the thermoelectric element 121 is in close contact with the flat portion P of the plate 123. Although the bottom surface of the thermoelectric element 121 is formed flat, due to the shape of the plate 123, the bottom surface of the thermoelectric element 121 does not come in close contact with the plate 123 as a whole, and preferably, a large part of the bottom surface is in close contact with the plate 123. A part of the bottom surface of the thermoelectric element 121 can be disposed apart from a part of the curved portion of the plate 123.

[0089] The heat sink 132 is in close contact with the top surface of the thermoelectric element 121. The heat sink 132 is disposed on the upper side of the flat portion P of the plate 123 with the thermoelectric element 121 interposed therebetween. The battery 141 is disposed on the upper side of the thermoelectric element 121 with the heat sink 132 interposed therebetween. The battery 141 is disposed on the upper side of the flat portion P of the plate 123 with the heat sink 132 and the thermoelectric element 121 interposed therebetween. That is, the thermoelectric element 121, the heat sink 132, and the battery 141 are stacked in this order on the upper side of the flat portion P of the plate 123.

[0090] Since the heat sink 132 and the battery 141, which are the components of the main body 100 that are heavy, are disposed on the upper side of the flat portion P of the plate 123, the thermoelectric element 121 and the plate 123 do not come apart even if the main body 100 is shaken violently.

[0091] The plate 123 includes an elliptical plate main body 1231 and a plate pin 1232 protruding from the periphery of the plate main body 1231.

[0092] Referring to Figure 10The plate pins 1232 can be formed at both ends in the long axis direction and both ends in the short axis direction of the plate body 1231. The plate fastening grooves 1112c into which the plate pins 1232 are inserted and are latched are formed at the periphery of the plate seating surface 1112. The plate fastening grooves 1112c can be formed at both ends in the long axis direction and both ends in the short axis direction of the plate seating surface 1112. Referring to Figure 11 The plate pins 1232 are inserted into the plate fastening grooves 1112c and are bent and joined to the outside direction of the plate seating surface 1112.

[0093] Referring to Figure 11 At least a part of the periphery of the plate body 1231 is disposed apart from the periphery of the plate seating surface 1112. The plate body 1231 can be cooled or heated by the thermoelectric element 121, thereby being contracted or expanded. It is preferable that a tolerance is left between the periphery of the plate body 1231 and the periphery of the plate seating surface 1112 so that a gap is not generated with the thermoelectric element 121 even if the plate body 1231 is contracted or expanded.

[0094] The above, although the preferred embodiments of the present application are illustrated and described, the present application is not limited to the above specific embodiments, within the scope of the claims required by the present application, the ordinary skilled in the art of the present application can make a variety of variations, and these variations should not be understood separately from the technical thought or prospect of the present application.
