1. When buying water toys, focus on the materials of baby water toys. This is the most critical place for water toys, the toughness of some materials is relatively weak, it is easy to break, if you fill the gas, plus the pressure of internal water pressure, it will be used to cause cracking, so you should pay more attention to his material when buying water toys, it is best to have a very strong toughness of the material, but also is environmentally friendly and non-toxic materials.
2. Whether there is a thickened explosion-proof inflatable change. After the baby water toy is inflated, if you add hot water to the pool, it will cause the air in the water toy to expand, if the water toy is inflated and changed too thin, it is easy to break, which is a thickened explosion-proof inflatable ring is very important, which can effectively prevent the water toy from cracking due to thermal expansion and cold contraction.
3. an air lock piece. As the name suggests, the air lock plate plays the role of air lock, and when inflating, you must keep pinching the air lock plate at the root of the air valve to open the crack, and it is difficult to inflate the air after that, and the same is true for giving up. This principle is similar to general inflatable toys, which do not have an inflatable function, and the gas inside is easy to leak out. With the gas lock sheet, under the premise that the air lock plate is not opened, it is basically difficult for the gas inside to leak out.
