1. Regular cleaning: Clean the surface of the horn regularly to remove dirt and corrosion that may be attached. Use mild detergent and soft cloth for cleaning, and avoid using corrosive chemicals such as strong acids and alkalis.
2. Inspection and replacement: Check the status of the horn regularly. If obvious corrosion, wear or cracks are found on the surface, replace it with a new horn in time to avoid affecting the extraction effect and equipment safety.

3. Lubrication: Lubricate the contact points between the horn and other parts of the equipment to reduce friction and wear, thereby extending the service life of the horn.
