What should I pay attention to when using the thermos for the first time?

Everyone knows what I do, right?Due to occupational diseases, editor will intentionally or unintentionally observe how friends and relatives around me use the thermos in daily life, especially the first use of the newly purchased thermos.Of course, the editor only occasionally points out the inadequacy of the other party's operation, which is probably a common problem for patients with obsessive-compulsive disorder.

The following editor summarizes the problems that consumers can avoid.

Step 1: check the appearance of the water cup

When you get a newly purchased thermos cup, you must first look at the outside to see if there are obvious defects in the appearance.These defects include manufacturing defects and shipping after sale.After confirming that there is no problem with the appearance of the water cup, the first step is to confirm that the function of the water cup is intact and the structure is complete.

Step 2: find the manual for the water bottle.

Check in detail whether there are special requirements and tips for the water cup in the manual, so as to avoid damage to the water cup due to the lack of understanding of the manual.Because some man-made damage merchants generally will not return or exchange for no reason.

Step 3: open the water bottle.

Carefully take out items such as certificates, appraisals, desiccants, etc. in the water cup.Some friends in this step will say that it is not said, and no one will use it without taking out the contents of the cup.But in reality this happens from time to time.Because everyone has to consider children and the elderly, some of them cannot judge and distinguish the difference between desiccant and tea bags.

Last year, a client friend called in an emergency. The water cup he gave to his friend was opened by the child at home alone and immersed in hot water. The desiccant was not taken out, and the child drank a whole glass of water.At present, the desiccant usually used in water cup factories is activated carbon, which is non-toxic by itself, so accidentally drinking it as tea bubble water will not cause any serious harm, but it will only cause gastrointestinal discomfort.But if you use it multiple times, it will definitely cause some degree of damage to the body.

Step 4: Pour a cup of room temperature water, close the lid and invert for 30 minutes to check for water leaks.

The editor knows that most of my friends won't do this step, and some friends pour in the drink after cleaning and start using it.However, the quality of some water cups is indeed substandard, causing slight omission of beverages, which may contaminate everyone's environment and clothing, and seriously damage some electronic products.

Step 5:confirm that there is no water leakage, you can clean the water cup.

The editor on how to clean the water cup has been described in detail in the previous article.Interested friends can read the previous article of the editor to understand.

Step 6:the water cup can be used after cleaning.

However, it is recommended that you do another insulation test on the water cup before going to bed, fill a cup of hot water, close the lid tightly and rest.Usually, everyone sleeps for 6-8 hours, which is also the international standard for the thermal insulation performance of water cups.Wake up in the morning and feel the temperature of the water in the cup. If there is no problem, you can use it with confidence.
