Thermos cup leakage causes and solutions

1. Reasons for water leakage in thermos cups:

1. 1. Aging of sealing ring: Thermos cups usually use silicone sealing rings to ensure sealing. Long-term use will cause the sealing ring to age or even break, resulting in water leakage.
2. 2. Loose cup lid: Some thermos cup lids may be loose, resulting in failure to ensure sealing, resulting in water leakage.
3. 3. Scale on the cup mouth: If the thermos cup is used for a long time, the inner wall of the thermos cup will scale, resulting in the cup mouth not being flat enough, affecting the sealing.
4. 4. Temperature difference: The water temperature in the thermos cup is too high or too cold, which will cause high temperature pressure, thus affecting the sealing.

2. Solution

1. 1. Replace the silicone sealing ring regularly: Replace it every 3-6 months according to the frequency of use.
2. 2. Check the sealing of the cup lid: You can test the front and back of the cup lid by pressure to confirm the sealing.
3. 3. Clean the inside of the thermos cup regularly: Use a special cleaning agent to clean it and brush the inner surface of the cup.
4. 4. Control the temperature of the drink: Avoid using overheated or overcooled drinks and control the temperature
