Heating cup mat

The utility model provides a heating cup mat which comprises an upper cover and a lower shell, a containing cavity is defined by the upper cover and the lower shell, a heating component is arranged in the containing cavity, heat dissipation holes are formed in the bottom of the lower shell, and a supporting piece and a stopping piece are arranged on the surface of the side, close to the containing cavity, of the lower shell. The stopping pieces correspond to the heat dissipation holes, a first heat preservation rib is connected between every two adjacent stopping pieces, and the supporting pieces are arranged on the peripheries of the stopping pieces. According to the heating cup mat, the stopping pieces are arranged around the heat dissipation holes, the first heat preservation ribs are connected between the stopping pieces and used for reducing transverse air flow, heat dissipation performance is met, meanwhile, loss of heat from the heat dissipation holes is delayed, rapid temperature rise of the heating c
