The bottom surface of the box body 21 is provided with the pressing plate 22, so the cleaning opening 221 is opened on the pressing plate 22, and the cleaning opening 221 is communicated with the box body 21 through the pressing plate 22, so that the box body 21 and the cleaning opening 221 are in a communicated state, and when the nozzle 1 is inserted into the box body 1, dry ice particles ejected by the nozzle 1 can be ejected through the cleaning opening 221. By covering the box 21 around the shower head 1, dry ice particles can be prevented from splashing around.

Further illustratively, the press plate 22 is used to press down on the upper surface of the battery 200 to improve the positioning accuracy of the battery 200. Cleaning openings 221 are formed in both sides of the pressing plate 22, and the cleaning openings 221 penetrate through the box body 21 so that dry ice particles are sprayed from the cleaning openings 221 to the battery liquid injection opening.

Optionally, a sealing part is arranged at the cleaning opening 221, and when the cleaning opening 221 is in contact with the battery liquid injection opening, the sealing part can prevent dry ice gas in the upper exhaust mechanism 2 from leaking out at the contact position between the cleaning opening 221 and the battery liquid injection opening, so that cross contamination is avoided.

Optionally, the cleaning device 100 further includes a lower air extraction mechanism 4, and the lower air extraction mechanism 4 is disposed below the conveying mechanism 3; the lower suction mechanism 4 comprises a housing 41, the housing 41 covers the bottom of the conveying mechanism 3 and corresponds to the cleaning port 221 in position, a second suction port 42 is formed in the bottom of the housing 41, and gas leaked from the cleaning port 221 is discharged through the second suction port 42.

As shown in fig. 1 and 2, a lower air suction mechanism 4 is provided below the conveying mechanism 3, wherein the lower air suction mechanism 4 corresponds to the position of the upper air suction mechanism 2 in the Z direction, when the electrolyte remaining at and near the battery liquid injection port is cleaned, dry ice particles are ejected from the cleaning port 221, and after the battery liquid injection port is cleaned, the gas leaked from the cleaning port 221 is discharged through the lower air suction mechanism 4, so that the dry ice gas after being utilized can be timely discharged by providing the upper air suction mechanism 2 and the lower air suction mechanism 4, thereby preventing cross contamination near the cleaning port 221 and discharging waste gas.

As shown in fig. 3, the lower suction mechanism 4 comprises a housing 41, wherein the housing 41 is arranged below the conveying mechanism, the cleaning opening 221 is opposite to the housing 41, a second suction opening 42 is formed in the bottom of the housing 41, the second suction opening 42 is externally connected with a suction fan, and the gas leaked from the cleaning opening 221 is discharged through the suction fan to prevent surrounding pollution.
