Description

Waterproof housing and power adapter Technical Field The application belongs to the technical field of power supply equipment, and particularly relates to a waterproof shell and a power supply adapter. Background The power adapter is used for converting alternating current input into direct current output, and is widely matched with small household appliances, water purifiers, air purifiers, security cameras, set top boxes, routers, lamp bars, massage instruments and other devices in modern life. The outer case of a conventional power adapter generally includes a housing and a cover body, which is provided to cover the housing to close an inner space of the housing. In the related art, the lid is provided with sealing flange, and the casing is offered and is used for holding the encapsulating groove of gluing, and sealing flange peg graft in the encapsulating inslot, carries out sealing connection's in-process to lid and casing, generally fills sealing glue to encapsulating inslot to with sealing flange and casing ultrasonic welding, however, carry out ultrasonic welding's in-process to sealing flange and casing, sealing glue can spill over to the outside of shell from encapsulating inslot, can not only lead to sealing glue to distribute unevenly in the encapsulating inslot, can also lead to the welding position between sealing flange and the casing to produce the gap, is unfavorable for improving the sealing performance of shell.
