[0025] Among them, the protective component 3 includes a groove 31 opened on the surface of the heating base 21, the charging port and the control switch of the heating base 21 are respectively located in the inner cavity of the groove 31, and the surface of the heating base 21 is rotatably connected with a cover 32 that can cover the groove 31 through a rotating shaft. The top of the inner cavity of the groove 31 is provided with a groove 33 that can provide a movable space for the cover 32 to rotate, and the inner wall surface of the cover 32 is provided with a seal.

[0026] It should be noted that the working principle of the above-mentioned heating base 21 is consistent with the heating base in a multifunctional new double-layer thermos cup disclosed in the existing publication number CN217885656U, which is the existing technology and will not be repeated in this technical solution.

[0027] Working principle: Place a finger in the inner cavity of the accommodating groove 38 and rotate the pull ring 39 upward by a certain angle, then pull the pull ring 39, so that the pull ring 39 drives the blocking cover 32 to rotate downward with the rotating shaft on the heating base 21 as the center, and the blocking cover 32 drives the rubber ring 34, the rubber plug 35 and the magnet 36 to rotate synchronously until the maximum limit, so that the charging port and the control switch of the heating base 21 can be exposed, and then the charging port of the heating base 21 can be used to charge the heating base 21, and the control switch of the heating base 21 can be used to control the heating base 21; after the operation is completed, rotate the blocking cover 32 upward until the blocking cover 32 is completely placed in the inner cavity of the embedded groove 31, the rubber ring 34 contacts the inner wall surface of the embedded groove 31, the rubber plug 35 is inserted into the charging port, and the magnet 36 is adsorbed on the iron block 37 by magnetic force, so that the charging port and the control switch of the heating base 21 can be shielded and protected.

[0028] Beneficial effect: By flipping open the cover 32, the charging port and the control switch of the heating base 21 can be exposed, and then the heating base 21 can be charged using the charging port of the heating base 21, and the heating base 21 can be controlled using the control switch of the heating base 21. After the operation is completed, the cover 32 is flipped closed to shield and protect the charging port and the control switch of the heating base 21, thereby preventing water from flowing into the inner cavity of the charging port when using the cup body assembly 1, and preventing the control switch from being accidentally touched when carrying the cup body assembly 1, thereby further extending the service life and safety of the heating assembly 2.

The above design can play a positioning role for the stopper 32, so that the stopper 32 can be stably placed in the inner cavity of the embedding groove 31, and prevent the stopper 32 from flipping over at will in the closed state.

[0034] Specifically, a receiving groove 38 is formed on the outer surface of the blocking cover 32, and a pull ring 39 is movably connected to the inner cavity of the receiving groove 38. The above design can facilitate the user to flip and open the blocking cover 32.

[0035] Specifically, the inner wall surface of the receiving groove 38 is rotatably connected to the pull ring 39 via a damping shaft. The above design can maintain the torsion angle fixing function, ensure that the pull ring 39 does not loosen after rotation, and ensure the stability of the pull ring 39 when it is received in the inner cavity of the receiving groove 38.

[0036] Specifically, the cup body assembly 1 includes an outer shell 11, an inner liner 12 is integrally formed in the inner cavity of the outer shell 11, a water storage cavity 13 is provided in the inner cavity of the inner liner 12, a vacuum cavity 14 is formed between the outer shell 11 and the inner liner 12, a heat receiving plate 22 is installed at the bottom of the inner liner 12, the bottom of the outer shell 11 is threadedly connected to the heating base 21, and a cup cover 15 is threadedly connected to the top of the outer shell 11.
