At the same time, the cup body 1 is provided with a charging assembly 2 and a key assembly 3.

[0042] Since the motor and the heating sheet generate heat during work, and heat is also generated during charging, a breathable structure needs to be provided to avoid pressure changes caused by heat generation, but a waterproof structure is also needed to prevent water from entering. Therefore, a waterproof and breathable piece is arranged on the cup body 1, and the waterproof and breathable piece is used to communicate the inside and outside of the cup body 1, so that the gas in the cup body 1 is discharged.

[0043] Therefore, in actual use, by arranging the waterproof and breathable piece, the inside and outside of the cup body 1 are communicated, so that the gas in the cup body 1 is discharged and the internal and external pressure balance is maintained, and at the same time, water is also prevented from being introduced into the cup body 1.

[0044] The charging assembly 2 and the key assembly 3 are relatively close to the place where heat is generated, and the charging assembly 2 itself also generates heat, so it is appropriate to arrange the charging assembly 2 and the key assembly 3, but since the key assembly 3 is not convenient to punch, it is arranged in the charging assembly 2.

[0045] The specific structure is as follows: as Figure 3 shown, the charging assembly 2 is located on one side of the heating area, and the waterproof and breathable piece is arranged on the charging assembly 2.

[0056] Therefore, in actual use, the sealing ring plays a role in sealing and waterproofing, thereby improving the waterproof rating, and connects the cup body 1 and the mounting part 22 by abutting against the protrusion 121 through the locking block 224.

[0057] Meanwhile, the connection structure between the mounting component 22 and the circuit board 21 is as follows: First, a hollow mounting post 225 is provided on the inner side of the mounting component 22, and the circuit board 21 has a hole 213 corresponding to the mounting post 225. Fasteners pass through the hole 213 and into the mounting post 225 to achieve the connection between the mounting component 22 and the circuit board 21. The fasteners are screws.

[0058] Furthermore, before fastener connection, preliminary positioning is required. The structure is as follows: First, the mounting component 22 is provided with a connecting post 226, and the circuit board 21 is provided with an assembly hole 214 corresponding to the connecting post 226.

[0059] Therefore, in actual use, the connection is achieved by matching the connecting post 226 and the assembly hole 214, and the mounting post 225 and the hole 213 are initially positioned and aligned before the fasteners are connected.
