[0028] The anti-detachment sealing structure described in this embodiment seals the cooling cavity 310 through the first sealing component 100, thereby ensuring that the clean cooling cavity 310 will not be contaminated again. When the cooling cavity 310 needs to be subjected to negative pressure vacuum evaporation treatment, based on the condition that the friction between the plug 120 and the cooling cavity 310 is greater than the friction between the sealing plug 220 and the sealing plate 140, the second sealing component 200 will preferentially detach from the first sealing component 100 under the action of the air pressure difference, thereby connecting the internal environment of the cooling cavity 310 with the outside world, thereby achieving the purpose of balancing the pressure difference between the internal and external environments, and avoiding the problem of the first sealing component 100 detaching from the cooling cavity under the action of negative pressure.
