When taking the baby out, the mother should prepare various equipment. You may need to feed your baby more frequently during the journey, so you need to prepare a good thermos cup. Can you hear the buzzing sound from such a good thermos cup? Can you hear buzzing from a good thermos cup? The better the thermos cup, the higher the vacuum degree of the middle layer, so the sound energy inside the thermos cup is more difficult to consume, and it can only be absorbed repeatedly through the inner wall. Because the inner wall is too thin, the sound generated by absorption falls very slowly. The slower the sound waves are, the more times they are superimposed, so the buzzing sound can be heard. The thermos cup is the most commonly used daily necessities for people. Friends who like to drink water will prepare one for themselves and their families when the weather is cold. However, there are many varieties and brands of thermos cups, and the quality is also good and bad. How should we choose a thermos cup? What should we pay attention to when choosing a thermos cup? 1. Material:
Stainless steel thermos cups must be food-grade 304 steel (the name 304 comes from the United States, the most popular name; Japan’s name is SUS304, and China’s GB name is OCr18Ni9, that is, 18-8), it is best to use 304 steel in the inner tank to ensure that the amount of heavy metals dissolved in the thermos cup used to hold water does not exceed the standard, including lead. The amount of heavy metal dissolved in cheap 201 or 202 stainless steel cups (produced in Yongkang, Zhejiang) is more than 100 times that of 304 steel! Heavy metals, including lead, exceed legal limits. Drinking such water can be very harmful to the human body. The outer casing does not matter. The cost of making 304 steel inside and outside is relatively high. When the wool comes out of the sheep, it costs the consumer's money. (If you make a 304 steel cup, the outer packaging will definitely have the material 304 written on it. This is easy to identify.) The inner cover is plastic, which is easier to identify as long as it smells odorless. The best thing is PC material (baby bottle material). When PC material is boiled in boiling water, it has no taste and will not deform. The rubber ring should be made of silicone, which is also a non-toxic material. The rubber ring is small and difficult to make, but it will not fall out. Silicone has good elasticity and toughness and is not easy to deform.
2. Vacuum insulation:
Vacuum is divided into tailless vacuum and tailed vacuum. The technology of tailless vacuum is more advanced, with high vacuum degree and good effect. Due to the difference in technology, More effective capacity.
3. Appearance:
If the thermos cup is beautiful in shape, people will like it. Of course, it also depends on the craftsmanship of the thermos cup, the workmanship of the details, and whether the interface is exquisite. Will the edge of the thermos cup be rounded and flat? A beautifully crafted thermos cup represents the manufacturer's emphasis on product quality.
4. Look at the inner cover
The inner cover of a good thermos cup is usually made of PC material. It smells odorless and the plastic is bright and smooth. The lid should be easy to remove, and there should be no hygienic blind spots that cannot be cleaned, so that it can be cleaned cleanly and used hygienically.
5. Twist the lid:
For a good-quality thermos cup, the lid should be very smooth and smooth when screwed on, and the force of the 360-degree rotation should be even. The thermos cup is used for drinking water. It needs to be opened and tightened several times every day. If the lid is uneven or makes a harsh sound when you first tighten it, the lid of such a thermos cup will break after a short time, leading to deflation and Water leakage.
