The radial width W2 of the outer ring heat insulation ring in the embodiment is 3-12 mm; w2 is slightly larger than W1, preferably W2 is 5-7 mm. When the radial width W2 of the outer ring heat insulation ring is less than 3mm, the heat insulation effect of the outer ring heat insulation ring 400 is poor, and the outer ring heat insulation ring is not easy to machine and form; when the radial width W2 of the outer ring heat insulation ring is larger than 12mm, if the size of the tray frame 100 is not changed, the winding length of the outer ring heating wire 220 is shortened, and the heating effect is poor; if the winding length of the outer ring heating wire 220 is not changed, the size of the tray frame 100 is increased, and further the overall size of the furnace body is increased, and the manufacturing cost is increased. Therefore, the radial width W2 of the outer ring heat insulation ring in the embodiment is most preferably 7mm, which is slightly larger than the radial width W1 of the inner ring heat insulation ring, so that the heat insulation effect of the outer ring heat insulation ring 400 can be ensured, and the heating effect of the outer ring heating wire 220 can be ensured or the overall size of the furnace body can be reduced. Of course, optionally, the radial width W2 of the outer ring heat insulation ring can also be 3mm, 4mm, 5mm, 6mm, 8mm, 9mm, 10mm, 11mm, 12mm, etc., as long as the radial width W2 of the outer ring heat insulation ring is between 3mm to 12mm, and it is all in the utility model discloses a protection scope.
