Optionally, the lower end of the sealing ring is inclined, and the side wall of the sealing ring is inclined in a direction away from the central line of the water filling port 2213 from top to bottom, so as to further improve the sealing effect between the anti-overflow element 23 and the water filling port 2213.

The embodiment also provides an air conditioner, which comprises an air conditioner internal unit and an air conditioner external unit which are connected. An outdoor unit of an air conditioner generally includes an outdoor heat exchanger. An air conditioner indoor unit generally includes an indoor heat exchanger, a throttle device, and a compressor. When the air conditioner performs refrigeration work, the compressor compresses a gaseous refrigerant into a high-temperature high-pressure gaseous state, and sends the gaseous refrigerant to the outdoor heat exchanger for cooling, the high-temperature high-pressure gaseous refrigerant is cooled and then becomes a medium-temperature high-pressure liquid refrigerant, the medium-temperature high-pressure liquid refrigerant is throttled and reduced by the throttling device and becomes a low-temperature low-pressure gas-liquid mixture, and the low-temperature low-pressure gas-liquid mixture absorbs heat in air by the indoor heat exchanger and is vaporized into a gaseous state, so that the refrigeration effect is achieved; the gaseous refrigerant returns to the compressor to continue to be compressed, and the circulation is continued to carry out refrigeration.
