[0010] Preferably, the bracket is fixedly connected to the inside of the shell, and the circuit board is fixedly connected to the bracket inside the shell via a pressing plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The DC charging port sealing and installation structure, by providing a circuit board, a bracket, a first sealing ring and a second sealing ring, can double-seal the charging port on the circuit board, effectively prevent water from entering the charging port, and ensure the normal use of the constant temperature bowl. The large hole of the first sealing ring and the outer wall of the charging port are provided with an interference fit, which can play a sealing role after assembly. At the same time, since the first sealing ring is assembled into the inside of the bracket, the first sealing ring will not be affected by production deformation when installing the charging port. The sealing performance is thus formed, thereby forming a first sealing structure to seal the inside of the shell. The second sealing ring is installed by inserting the sealing plug into the installation groove, and the outside of the shell can be sealed by the second sealing ring. At the same time, the first sealing ring can play a normal sealing effect when the second sealing ring fails or is damaged, forming a second seal, and playing a double sealing effect to prevent oil stains, dust and other debris from entering the charging port, thereby ensuring the normal use of the constant temperature bowl charging function.

[0013] 2. The DC charging port sealing and mounting structure is provided with a first guide groove, a second guide groove, a second sealing ring and a mounting groove, which can prevent the silicone plug from being disengaged while facilitating installation. After the DC component is assembled, the DC component is installed on the shell and fixed by a pressing plate. The bracket is provided with a second guide groove for assembly, and the pressing plate is also provided with a first guide groove, and the two sets of guide grooves are directly provided with interference. When the pressing plate is installed downward, the DC component can be moved toward the inner wall of the shell through the interference fit between the guide grooves, thereby ensuring that the first sealing ring on the DC component better fits the inner wall of the shell, and the mounting groove is designed with a large outer and small inner structure, which can not only ensure that the second sealing ring is easy to install, but also prevent the sealing plug from being easily disengaged.
