The rotating frame 91 is coaxially fixed on the rotating shaft 11, and two swing arms 94 are arranged on the rotating frame 91. One end of the two swing arms 94 away from the rotating shaft 11 is used to fix the first elastic member 92 or the second elastic member 93. The pulling force generated by the first elastic member 92 and the second elastic member 93 on the swing arm 94 is used to form a torque on the rotating shaft 11, and the first elastic member 92 and the second elastic member 93 are adjusted. When the center of gravity of the heat preservation front body 31 is directly above the rotating shaft 11, the pulling force of the first elastic member 92 and the second elastic member 93 on the rotating frame 91 are both zero. Then, when the heat preservation front body 31 continues to rotate in the direction of opening the accommodating chamber 33, the rotating shaft 11 drives the rotating frame 91 to rotate, so that the first elastic member 92 generates elastic force and gradually increases, so that the first elastic member 92 can generate resistance to the rotation of the heat preservation front body 31, and when the heat preservation front body 31 is opened to the maximum position, the pulling force of the first elastic member 92 reaches the maximum, and the torque on the rotating frame 91 is also the maximum, so that it can provide assistance when the heat preservation front body 31 is closed, and at the same time, the speed at the end of the movement can be slowed down when it is closed. On the contrary, when the heat preservation front body 31 is closed and fits with the heat preservation rear body 32, the elastic force of the second elastic member 93 is the largest, and it can provide assistance when the heat preservation front body 31 is opened to facilitate opening. The first elastic member 92 and the second elastic member 93 can be set as rubber strips or tension springs.

[0034] A slide rail 95 is fixedly arranged on the inner wall of the electrical box 2, and the slide rail 95 is slidably connected to the mounting block 96.
