1. A liquid loading device for loading liquid into a product, the product comprising a liquid inlet, an air outlet, and a cavity, the liquid inlet and the air outlet communicating with the cavity, the liquid loading device comprises:
a loading module configured to load liquid into the cavity through the liquid inlet;
a pressure sensor configured to sense a pressure in the cavity and generate at least one pressure value;
an air extraction module configured to extract air in the cavity through the air outlet; and
a controller coupled to the loading module and the air extraction module, the controller configured to control the air extraction module to operate based on related data, and the related data comprising at least one of a duration, the at least one pressure value, and a loading amount of liquid loaded into the cavity,
wherein the at least one pressure value comprises a first negative pressure value, the controller is further configured to control the loading module to stop loading the liquid into the cavity when the first negative pressure value matches a first preset pressure value;
wherein the control module is further configured to control the air extraction module to start extracting air before or when the liquid is started loading into the cavity, and to stop extracting air before the liquid is stopped loading into the cavity.
