What is an "electric air pump"??? As the name implies: it is an inflatable tool driven by electricity.
Many friends have come into contact with children's inflatable pools, inflatable mattresses and other inflatable daily necessities, they will use this tool. And how to be
Which tool to choose?
The editor has the following points, which only represent personal views for reference:
1. Appearance:
Household electric air pumps are used at home, so the volume should not be too large. It is best to hold it in the palm of an adult. Because it's too big to hold,
If you encounter a larger product, the inflation time is too long, the hand is sore, the product is too small and there is no sense of "control".
2. Wire plug:
All electric air pumps on the market now have two types of plugs (only the one that is plugged in for household use), one is a flat plug and the other is a round plug.
Anyone who knows electrical engineering knows that in China, all socket designs are designed for flat plugs, and round plugs are only suitable for some European regions and countries.
For home use, round plugs are not suitable for use in China. Although some sockets can also be plugged in, the specifications of round plugs are different.
It is easy to cause poor contact after entering. However, this phenomenon does not occur with flat plugs.
3. Excessive fever:
Nowadays, the electric air pump used in China, because of market competition and cost suppression, some manufacturers use some inferior motors for charging.
The driving motor of the air pump, and because of many materials or not meeting a requirement of the product itself, there will be a sharp heat during use.
In severe cases, short-circuit, black smoke and other phenomena may also occur. Therefore, when purchasing an electric air pump, you must try it yourself
First, if under load, the electric pump does not feel the heat until the palm of the hand takes about 1 minute to 2 minutes, it is normal, otherwise it is abnormal.
4. Noise:
Regarding noise, I want to popularize the distinction between noise values. Under normal circumstances, our face-to-face communication problems are around 60-65 decibels.
Loud quarrels can go as high as 100-120 decibels, depending on the individual's voice. And the noise value of the positive collapse of the air pump, the noise value of the household
Normally it is around 70-75 decibels, too low, indicating that the power of the product is insufficient, too high, indicating that the power of the product is too high.
