[0023] Installed next to the massage chair circuit board, when the humidity sensor 19 detects that the humidity is too high, the semiconductor refrigeration sheet 1 is started, and the cooling surface of the semiconductor refrigeration sheet 1 reduces the temperature of the heat-absorbing fins 4, and the moisture in the air condenses into water droplets when it is cold, and falls into the air deflector 5 under the action of gravity, and enters the receiving box 8 in the installation cover 6 through the air deflector 5. Through the above process, when the humidity sensor 19 detects that the humidity is too high, the semiconductor refrigeration sheet 1 is started, so that the moisture in the air condenses into water droplets when it is cold, thereby reducing the moisture in the air next to the massage chair circuit board, thereby protecting the massage chair circuit board, and solving the problem that when the air humidity is saturated and it is easy to condense into water droplets on the surface of objects during the return of south wind, the massage chair circuit board is affected by water vapor and is prone to short circuit.

[0027] When the receiving box 8 is full, under the action of gravity, the gravity of the receiving box 8 acts on the protrusion 11 through the rotating shaft 7 and the rotating ring 10, causing the protrusion 11 to slip and disengage from the retaining spring 12.
