How to choose the correct table fan?
Table fan cover mesh welding point inspection: Use a few fingers to gently move a few circles on the cover ray, if the sound from individual rays is inconsistent, it means that there is false welding (will be desoldered).
Table fan swing control check: When the red dot of the knob turns from zero to 90°, the machine head should swing and shake its head. Going back to zero should stop shaking your head.
table fan key check: two keys are pressed at the same time, and they should rebound at the same time after they are released from the hand. If they do not rebound, it is not good. Once a key has been pressed, when the second key is pressed again, the first key should be able to rebound automatically, otherwise it will not work.
Table fan appearance parts inspection: carefully observe from top to bottom whether there is any cracking phenomenon. By mastering the above methods, you can choose the desired table fan. Generally speaking, the product quality of the old factory is relatively stable.
