Therefore, the user should check whether the 3C mark is attached to the product when purchasing the sprayer.

The method is to inject clean water into the bucket, close the switch, and shake the rocker repeatedly until it cannot shake. Check whether there is any leakage in the outlet joint of the air chamber to the switch to see whether the connection of each part is good and whether there is damage. Then turn on the switch and shake the rocker to see if the mist flow is even, the atomization is good, there is no intermittent spray phenomenon, and there is no leakage at the joints of various parts.
