Why is there an abnormal sound inside the thermos cup after it has been used for a period of time?（two）

Why does the getter fall off? Can it be corrected to the original position after falling off, and the abnormal noise will no longer occur? The reason for the getter falling off is mainly caused by improper welding.The getter is very small. In the welding process, the welding position is usually small and the welding time is fast, so it is inevitable that some getters will have problems such as virtual welding, and the water cup must be processed in a vacuum furnace at 600 ° C for 4 hours.

Some getters with problems such as false welding and false welding will cause desoldering of solder joints or aggravation of false welding due to long-term high temperature. The thermos cups with abnormal noise will be eliminated before leaving the factory, but those water cups with weak welding cannot be checked out because they did not fall off at that time, and they are put into the market. When consumers buy and use, due to external force impact or knock, the getter of the weak welding falls off, causing abnormal noise.

There is no way to repair the getter after it falls off. Because the entire water cup is completely welded by laser welding, it cannot be opened for maintenance like other products. However, some consumers shake it vigorously after discovering the abnormal sound, so that the getter is stuck between the interlayers at the bottom of the cup.But most of the time the getter will drop again.

Does the noisy water cup affect the use? Except for the abnormal sound during use, the abnormal sound water cup has the same functions as the good product water cup, and will not reduce the heat preservation effect due to the getter falling off, nor will other functions of the water cup be damaged due to the getter falling off. But as far as I know, many of my friends are somewhat obsessive-compulsive, and always feel that using it affects their mood.Then it depends on the length of time you bought it. If it is less than 7 days, you should return it quickly. If it exceeds the use, it depends on your needs.
