[0026] Working principle: When in use, firstly, the storage tank body 4 adopts an integrated molding design, which ensures the structural integrity and sealing of the tank body and reduces the potential risk of leakage. The top of the storage tank body 4 is sealed by the sealing assembly 5, and the inner sealing cap 51 is threadedly connected to the outer wall of the top of the storage tank body 4 to form the first sealing line of defense. The sealing platform 52 further enhances the sealing effect, and the outer sealing cap 53 is threadedly connected to the outer wall of the top of the sealing platform 52 to provide double sealing protection for the vaccine.

[0027] A protective cover 1 is provided on the outside of the storage tank to protect the storage tank body 4.
