When it is necessary to increase the temperature in the heat preservation shell, after the air passes through the fixed shell 301, it enters the control chamber 5. When the temperature rises, the control chamber 5 expands through the reed 501, driving the pressure rod 502 to rise and pressing down the push switch 504. After the push switch 504 is pressed down, the external pumping device stops pumping the hot heat exchange liquid into the input pipe 401, so that the temperature in the heat preservation sleeve 101 is maintained at an appropriate level. When it is necessary to dissipate heat, the cold heat exchange liquid is input into the heat exchange chamber 4, so that the cold air is input into the heat preservation sleeve 101 through the fixed pipe 303.
