Who are the users of waterproof and electric shock-proof sockets?

Zhongke electrician's waterproof and electric shock-proof socket is good. It was shown at the exhibition some time ago. It looks pretty amazing. When the socket is electrified, it will be put into the water, and the hand will not get an electric shock when it is put into the water. Single-hole plug-in jack does not supply power, effectively preventing children from accidentally getting an electric shock when inserting fingers or metal equipment. It seems to be sold in JD.COM. After listening to their introduction, it seems that they have obtained eight patents. Parents with children at home can have a look, but the picture books at the exhibition can't be found now.
