Electrothermal constant temperature mattress

The utility model discloses an electrothermal constant temperature mattress, it includes protective layer, heat dissipation layer, heat preservation, phase change layer, capillary stratum reticulare, heat dissipation level in protective layer below, the heat preservation is for the energy storage thermostat layer and below lieing in the heat dissipation layer, and the phase change layer is for temperature adjustment layer and lie in the heat preservation below, and the capillary stratum reticulare is for the heating stratum reticulare and lie in the phase change layer below. Electrothermal constant temperature mattress heat conduction is fast, can last constant temperature ten hours after the outage, facilitates the use.
