A hand warmer charging case includes an accommodating housing and an accommodating cover. The accommodating housing is provided with a storage space for storing a target hand warmer. The accommodating housing is further provided with an accommodating space. The accommodating space is configured to accommodate a rechargeable power supply and a circuit board matched with the rechargeable power supply. The accommodating cover is movably connected to the accommodating housing in a movable manner, and is configured to close or open the storage space. During use, the accommodating cover that cooperates with the accommodating housing is opened to opening the storage space provided in the accommodating housing. A power bank hand warmer that needs to be charged or is temporarily in idle is put into the storage space, and the accommodating cover that cooperates with the accommodating housing is closed, thereby closing the storage space provided in the accommodating housing.

A temperature regulation system for regulating the temperature of a portion of a body, in particular of a user's body. The system comprises one humidity sensor for measuring humidity in the vicinity of the portion of a body, one temperature adjustment element for providing heat to a portion of the body, a memory unit for storing one threshold humidity related value (H.sub.thresh) and one reference user information related values (t.sub.ref, .sub.ref), a controlling unit in communication with the humidity sensor, with the memory unit and with the temperature adjustment element, and configured to determine one instant user information related value (t.sub.inst, .sub.inst), perform a comparison between one instant user information related value (t.sub.inst, .sub.inst) and one triggering user information related value (t.sub.trig, .sub.trig) based on said reference user information related value (t.sub.ref, .sub.ref), activate the temperature adjustment element to provide heat to a portion of the body depending on the result of said comparison. The controlling unit is further configured to receive one instant humidity (H.sub.inst) measured in the vicinity of the portion of the body from the humidity sensor, perform a comparison between said instant humidity related value (H.sub.inst) and one triggering humidity related value (H.sub.trig) based on said threshold humidity related value (H.sub.thresh), and to set the one triggering user information related value (t.sub.trig, .sub.trig) to a value lower than said reference user information related value (t.sub.ref, .sub.ref) when the instant humidity related value (H.sub.inst) is greater or equal to said threshold humidity related value (H.sub.thresh).

The present invention provides devices for cooling and heating an individual's neck. Devices of the invention include two heating and cooling members that each a contoured surface for resting against a side of a user's neck and are coupled together via a bridge portion. The members each include a temperature assembly. The temperature assembly includes a heating and cooling module positioned against the contoured surface of the member. The temperature assembly may also include a heat sink, a fan, or both. The device further includes a controller for controlling the temperature assembly.

A sleeve assembly is configured to provide heat therapy and massage therapy simultaneously. The sleeve assembly an outer sleeve operatively connected to an outer layer, a first pocket, and a second pocket. A rechargeable battery pack with controls is arranged in the second pocket through a second pocket opening. A heating element assembly is arranged within the first pocket through a first pocket opening attached to the rechargeable battery pack with controls with a cord. A user can wrap the outer sleeve around an arm to provide heat therapy and massage therapy to a client simultaneously.

Eye compresses including a strap, a patch, and an electric heating element. The strap is configured to selectively couple to a head of a user. The patch is coupled to the strap and configured to cover an eye of the user when the strap is selectively coupled to the head of the user. The patch defines a pocket with an interior and a pocket opening. The electric heating element is disposed in the interior of the pocket. The electric heating element is configured to selectively generate heat when electrically coupled to a power source.

A portable hand warmer charging case includes a case body. A placement chamber configured to place a hand warmer unit for charging is provided on the case body. The case body is provided with a first circuit board, a first charging unit, and a first battery. The first battery and the first charging unit are electrically connected to the first circuit board. When the hand warmer unit is placed in the placement chamber, the first circuit board is configured to output electrical energy, which is output by the first battery, from the first charging unit; and the first charging unit is configured to be adapted to a second charging unit on the hand warmer unit for use and transmit the electrical energy output by the first circuit board to the second charging unit on the hand warmer unit.
