The middle part of the lower abutting boss 43 protrudes downward, and the edge extends toward the protrusion and abuts against the bottom wall of the protrusion. The edge of the lower abutting boss 43 always abuts against the bottom surface of the protrusion 3, and when the sliding part 41 slides upward in the through hole 32, the middle part of the lower abutting boss 43 can deform and slide upward with the sliding part 41. A compression spring 45 is sleeved on the sliding part 41, and one end of the compression spring 45 abuts against the lower abutting boss 43, and the other end abuts against the bottom wall of the upper abutting boss 42. There is a gap between the sliding part 41 and the side wall of the through hole 32, and a first sealing ring 46 that can seal the through hole 32 is provided on the bottom wall of the upper abutting boss 42. When it is necessary to put items into vacuum insulation, the vacuum equipment is extended into the cavity 31 and cooperated with the vacuum one-way valve 4 to pull the vacuum one-way valve 4 upward, the compression spring 45 is compressed, and the first sealing ring 46 is separated from the through hole 32 to release the seal at the through hole 32. At this time, the air in the tank is discharged from the exhaust hole 44 through the gap between the sliding part 41 and the side wall of the through hole 32; after the air in the tank body 1 is discharged, the vacuum equipment is taken out to separate the vacuum equipment from the vacuum one-way valve 4. At this time, under the action of the elastic force of the compression spring 45, the pressure one-way valve quickly returns to the initial state, and the first sealing ring 46 closes the through hole 32, so that the interior of the tank body 1 is in a vacuum state, and the stored items in the tank are vacuum preserved, thereby extending the storage time of the items. The smoldering tank of this scheme can not only smolder and keep warm objects or fluids, but also vacuum preserve items that need to be preserved.

[0031] like Figure 4 As shown, the diameter of the sliding portion 41 matches the diameter of the through hole 32, and a vacuum channel 33 is provided in the through hole 32 vertically downward along the through hole 32. When the vacuum one-way valve 4 is acted upon by the vacuum equipment, the vacuum one-way valve 4 slides toward the outer cover 21, and the air in the tank body 1 flows out of the tank body 1 through the exhaust hole 44 through the vacuum channel 33 under the action of the vacuum equipment. When the vacuum one-way valve 4 is separated from the vacuum equipment, the vacuum one-way valve 4 is reset, and at this time, the first sealing ring blocks the through hole 32 and the vacuum channel 33.
