Description

Technical Field

[0001] The utility model belongs to the technical field of cylindrical batteries, and in particular relates to a tool cleaning pen suitable for cleaning a liquid filling port of a cylindrical battery. Background Art

[0002] At present, in the production of cylindrical batteries, the injection port of cylindrical batteries is laser cleaned before laser welding. However, the battery injection port before laser cleaning often has electrolyte crystals and other residues, which need to be wiped and cleaned manually in advance. The disadvantage of manual cleaning is that the injection port is small, generally within 10mm in diameter, and the fingers are relatively thick, which is not convenient for manual operation. Even long-term manual wiping can easily cause swelling and pain in the hand area, so the cleaning speed is slow and the cleaning effect is unsatisfactory. Summary of the invention

[0003] The utility model aims to provide a tool cleaning pen suitable for cleaning the liquid filling port of a cylindrical battery, so as to solve the problems existing in the above-mentioned background technology.

[0004] The purpose of the utility model is achieved as follows: a tool cleaning pen suitable for cleaning the liquid filling port of a cylindrical battery, which comprises a pen body, an outer tube is arranged on the outside of the pen body, a ball is movably clamped at the bottom of the outer tube, an inner hose is arranged inside the outer tube, and a drip outlet is arranged at one end of the inner hose close to the ball.

[0005] The inner hose and the outer tube are connected and fixed via a clamping seat.

[0006] A drip bucket is integrally arranged on the top of the inner hose.

[0007] An injection tube is arranged outside the drip bucket.

[0008] An injection tube rubber plug is arranged on the top of the injection tube.

[0009] An outer tube rubber plug is arranged on the top of the outer tube.

[0010] An adjusting switch is arranged on the outer side of the inner hose.

[0011] The beneficial effects of the utility model are as follows: the device can effectively replace manual labor, facilitate the cleaning of electrolyte crystal residues at the cylindrical battery injection port, and improve the cleaning efficiency. The cost is low and the operation is convenient. While effectively cleaning the cylindrical battery injection port, secondary pollution can also be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings. Example

[0016] like Figure 1-2 As shown, a tool cleaning pen suitable for cleaning the liquid filling port of a cylindrical battery comprises a pen body, an outer tube 1 is arranged on the outside of the pen body, a ball 2 is movably clamped at the bottom of the outer tube 1, an inner hose 3 is arranged inside the outer tube 1, and a drip outlet 6 is arranged at one end of the inner hose 3 close to the ball 2.

[0017] The inner hose 3 and the outer tube 1 are connected and fixed via a clamping seat 9 .

[0018] A drip funnel 4 is integrally arranged on the top of the inner hose 3 .

[0019] An injection tube 5 is arranged outside the drip bucket 4 .

[0020] The top of the injection tube 5 is provided with an injection tube rubber plug 8 .

[0021] An outer tube rubber plug 7 is arranged on the top of the outer tube 1 .

[0022] An adjusting switch 10 is arranged on the outer side of the inner hose 3 .

[0023] When the utility model is in use, a person holds the pen body with one hand and uses the other hand to place non-woven fabric in the area of ​​the cylindrical battery injection port 11, and then evenly rolls the ball 2 around the injection port 11, especially in the area where there are obvious electrolyte crystals and other dirt. During the cleaning process, the cleanliness of the cylindrical battery injection port 11 area is visually checked, and according to the cleanliness, repeated rolling and wiping and timely replacement of clean non-woven fabric can be selected until it is visually clean and can be transferred to the laser cleaning process. Example

[0024] like Figure 1-2 As shown, a tool cleaning pen suitable for cleaning the liquid filling port of a cylindrical battery comprises a pen body, an outer tube 1 is arranged on the outside of the pen body, a ball 2 is movably clamped at the bottom of the outer tube 1, an inner hose 3 is arranged inside the outer tube 1, and a drip outlet 6 is arranged at one end of the inner hose 3 close to the ball 2.

[0025] For better effect, the inner hose 3 and the outer tube 1 are connected and fixed by a clamping seat 9. The clamping seat 9 can prevent the inner hose from being offset.

[0026] For better effect, a drip bucket 4 is integrally provided on the top of the inner hose 3 .

[0027] For better effect, an injection tube 5 is arranged outside the drip bucket 4. Cleaning liquid can be added to the inside of the drip bucket 4 through the injection tube 5.
