The electric heating device 11 and the lower sensor assembly 12 are fixed at the top end of the support beam 28. The electric control system 16 is fixed with the heat preservation box 1.

[0036] The use of the collecting groove 27 can better gather and collect the condensed water discharged from the drain port 25, avoiding the inconvenience of cleaning caused by random flowing. The use of the support beam 28 can make the electric heating device 11 and the lower sensor assembly 12 away from the condensed water, which is more safe.

[0037] The collecting groove 27 is fixed with a downward penetrating drain pipe 29. The bottom of the drain pipe 29 is provided with a detachable blocking piece. The outer wall of the heat preservation box 1 is fixed with vertical support legs 31 in front and back. The bottom ends of the support legs 31 are flush with each other, and the bottom ends are lower than the bottom end of the drain pipe 29.

[0038] By detaching or installing the blocking piece, whether the condensed water collected by the collecting groove 27 is discharged through the drain pipe 29 can be used, so that the cleaning of the condensed water is more convenient.

[0039] The blocking piece is a screw cap 32. The screw cap 32 is in sealing thread connection with the outer wall of the bottom of the drain pipe 29.

[0040] The screw cap 32 is used to block the drain pipe 29, avoiding the continuous discharge of the condensed water from the drain pipe 29.

[0041] The sealing member is a plug 33 made of dense fabric or sponge, which is plugged into the bottom of the drain pipe 29.

[0042] The plug 33 can continuously drain the condensed water, greatly reducing the pollution of the condensed water evaporated by microorganisms to the pears, and greatly reducing the circulation of air from the drain pipe 29 to the outside, reducing the interference of the outside air to the heat preservation box 1.
