Refer to shown in Fig. 1, a kind of muff, be sleeved on the outside of spontaneous heating pot, muff comprises side heat insulation wall 10 and end heat insulation wall 20, and side heat insulation wall 10 is fitted with the lateral wall of the outer pot of spontaneous heating pot, and end heat insulation wall 20 fits with the exterior bottom wall of outer pot.Refer to shown in Fig. 2, side heat insulation wall 10 and end heat insulation wall 20 include insulation internal layer 11 sheathed successively from the inside to the outside and protection outer 12, and insulation internal layer 11 comprises the first sheathed successively from the inside to the outside heat-reflecting layer 111 and foaming layer 112.
The first heat-reflecting layer 111 is adopted by reflect heat on outer pot, to avoid heat to be dispersed in air; The heat transfer coefficient of foaming layer 112 is relatively very low (particularly relative to conventional silica gel), and heat transfer rate is slow, slow down the transmission speed of heat, serves the effect of insulation.
The temperature that muff can solve spontaneous heating pot outer pot outside is in use higher, the problem that user easily scalds accidentally.Meanwhile, muff can be reached for pot, and the effect of particularly spontaneous heating pot insulation, makes spontaneous heating pot can gather more heat for heat food, thus has expanded the food materials type that spontaneous heating pot can cook to a certain extent.Because heat insulation effect is better, the heating material that muff can also improve spontaneous heating pot is contracted for fixed output quotas the utilization rate of heat-dissipating amount, extends the service time of heating material bag.
