Figure 1 It is drawn but not marked in the figure. This is a conventional structure of the zirconia high temperature sintering furnace 1 and will not be described in detail here.

[0022] In the utility model, a heat inlet hole 100 is provided at the bottom of the zirconia high temperature sintering furnace 1 , and the heat inlet hole 100 is connected to a positioning groove 101 .

[0023] In the utility model, an electric push rod 2 is horizontally installed in the positioning groove 101, and the output end of the electric push rod 2 is fixedly connected to a heat-resistant plate 3, and the heat-resistant plate 3 is located on the top of the high-temperature hose 4; the electric push rod 2 is used to drive the heat-resistant plate 3 to shield the high-temperature hose 4 from working. When the zirconia high-temperature sintering furnace 1 is heated inside, the heat-resistant plate 3 is used to shield heat loss. When the zirconia high-temperature sintering furnace 1 is heated and the denture crown is taken out, the heat-resistant plate 3 leaves the high-temperature hose 4 to allow the hot air blower 5 to absorb the heat in the zirconia high-temperature sintering furnace 1 into the heat pipe waste heat recovery device 6.
