1. A cleaning method for a negative-pressure component for battery formation, wherein the cleaning method for a negative-pressure component for battery formation uses a cleaning tool for a negative-pressure component for battery formation, the negative-pressure component comprising a negative-pressure cup and a suction nozzle, wherein the cleaning tool comprises:
a storage cup, wherein the storage cup is configured to engage with the negative-pressure cup, and the storage cup is communicated with an air source; and
a liquid guide member, wherein the liquid guide member is provided with a liquid guide channel, and an inner cavity of the storage cup is communicated with the negative-pressure component through the liquid guide channel;
wherein a first end of the liquid guide member is configured to communicate with the negative-pressure component, and a second end of the liquid guide member is extended from a mouth of the storage cup into the storage cup; and
a second check valve, wherein the second check valve is communicated with the storage cup;
wherein cleaning method for negative-pressure component for battery formation comprises:
the injecting a cleaning liquid into the storage cup;
communicating the negative-pressure component with the first end of the liquid guide member, wherein the liquid guide member is connected with the storage cup;
activating a negative-pressure power source connected with the negative-pressure component, wherein the cleaning liquid in the storage cup enters the negative-pressure component through the liquid guide member;
triggering the second check valve, wherein air enters the storage cup from the air source through the second check valve to replenish an air flow to the negative-pressure cup; and
sucking air to the cleaning liquid in the negative-pressure component by negative-pressure through the second end of the liquid guide member and cleaning the negative-pressure component, when a level of the cleaning liquid in the storage cup is decreased to or below the second end of the liquid guide member.
