Lithium batteries, as a type of clean energy battery, are widely used. Battery electrodes are an important component of lithium batteries, and the production of battery electrodes is a process in battery production. During the production of battery electrodes, they need to be dried in an oven. During the drying process, when the electrodes move inside the oven, the surface of the electrodes is covered with slurry that is not completely dried. During start-up, shutdown, or debugging, the slurry that is not dried can easily stick to the nozzle. Therefore, the nozzle needs to be cleaned and maintained frequently.

The specific choice can be made according to the actual situation.

[0033] In one embodiment, such as Figure 3 and Figure 4As shown, one of the first extension 304 and the second extension 305 is provided with a fitting part 306, and the other is provided with a fixing part 307; the fitting part 306 is provided with a first through hole adapted to be rotatably sleeved on the rotating shaft 5; the fixing part 307 is provided with a second through hole adapted to be rotatably sleeved on the rotating shaft 5; the fixing part 307 is provided with a fourth groove 308, and the fitting part 306 is adapted to be fitted into the fourth groove 308; the first extension 304 and the second extension 305 are sleeved on the rotating shaft 5 through the fitting part 306 or the fixing part 307.

A second groove is provided in the stepped portion 3031. The width of the stepped portion 3031 gradually narrows in the direction away from the second groove. The thickness of the clamping portion 3032 gradually increases in the first direction in the direction away from the stepped portion 3031. The first brush head 301 and the second brush head 302 are both provided with clamping ports 7 and stepped ports 8 on the side facing the suction nozzle 303. The clamping portion 3032 is clamped between the two clamping ports 7, and the stepped portion 3031 is clamped between the two stepped ports 8.

[0036] It should be noted that the step portion 3031 and the clamping portion 3032 are integrally formed; the first direction, the second direction and the third direction are perpendicular to each other.

During cleaning, the vacuum cleaner body 402 generates negative pressure by holding the handle 403, which causes the cleaned impurities to be adsorbed into the chamber 401 through the suction port 310 for collection, making cleaning and processing convenient.

[0050] In one embodiment, such as Figures 1 to 3 As shown, the oven nozzle cleaning tool also includes a vibration component 10, which is mounted on the brush head component 3.
