Preferably, a sealing ring is arranged between the inner folding part and the turnover part of the shell.

Compared with the prior art, the utility model has the beneficial effects that: by adopting the technical scheme, the vacuum layer plays a role in heat preservation, the heat conducting material in the heat conducting layer plays a role in conducting hot water heat to the shell, so that the outer wall of the cup can be heated to warm hands, and meanwhile, the temperature of hot water can be accelerated to fall, and the cup is convenient to drink. The addition of the heat-conducting substance is carried out after the vacuum-pumping process, and the production process has low requirements.

The further beneficial effects are that: the heat conducting substance is heat conducting powder particles or a mixture made of metal or alloy, particularly iron, copper, stainless steel powder particles or a mixture thereof, and has good heat conducting property and flowing property, and can effectively conduct heat.

Still further beneficial effect is: the heat conducting material is heat conducting liquid, and the liquid heat conducting material enables the connection between the inner container and the shell to be more compact, so that the heat conducting efficiency is improved.

Still further beneficial effect is: the cup mouth welding position is in the outside below, does not contact with the oral area nor with food contact, even the welding position desolders and leads to heat-conducting material to leak and also can not make the user drink by mistake, and the security is higher. The provision of the seal ring can further prevent the above problems from occurring.

Detailed Description

In order to make the technical solution of the present invention clearer, the present invention will be described in detail below with reference to fig. 1 to 3. It should be understood that the detailed description and specific examples, while indicating the scope of the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.

The utility model relates to a novel hand warming cup, wherein an opening part of a liner 2 is fixed on the middle upper part of a liner 3 through welding, the welding position can be below a shoulder part of the liner, heat can be transferred above the shoulder part of the liner to form a heat conducting section 31, a vacuum section 32 is arranged below the shoulder part of the liner, a vacuumizing hole is arranged at the bottom of the liner 2, a cavity between the liner 2 and the vacuum section 32 of the liner is vacuumized to form a vacuum layer 5, a shell 1 and the liner 3 are fixedly welded on the opening part, the bottom of the shell 1 is fixedly welded with the upper end part of a cup bottom 4, a cavity surrounded by the shell 1, the liner 2, the cup bottom 4 and the heat conducting section 31 forms a heat conducting layer 6, and a flowable heat conducting substance 7 is filled in the heat conducting layer 6. When the cup is upright, the height of the heat conducting substance 7 deposited and accumulated does not exceed the vacuum layer 5, so that the cup is in a heat preservation state, when the cup is turned upside down, the heat conducting substance 7 flows to the heat conducting section 31, in order to ensure the hand warming effect, the height of the heat conducting substance 7 accumulated at the moment needs to reach 50 percent, preferably 70 percent of the height of the cup at least, and hot water in the cup is transferred to the heat conducting substance 7 through the heat conducting section 31 and then transferred to the shell 1.
