The heat insulation material is formed by foaming a foaming material injected between the outer wall and the inner wall. The shell has a filling hole formed in the outer wall, and a baffle plate located between the outer wall and the inner wall and used for closing the filling hole. The baffle plate is connected to the outer wall. The filling hole includes a near end close to the connecting end and a far end away from the connecting end. The outer wall inclines towards the inner wall in a direction from the near end to the far end on an area on which the filling hole is disposed.
