Abstract

The invention discloses a waterproof power adapter with low loss and high heat dissipation. The waterproof power adapter comprises a shell, wherein a heat dissipation opening is formed in the center of the right end face of the shell, a waterproof mechanism is arranged in the shell and the heat dissipation opening, the waterproof mechanism comprises waterproof grooves, a water-swelling rubber water-stop strip, an elastic groove, a water baffle, a ferromagnetic plate, a tension spring, a water stop groove, an electromagnet, a storage battery, a first metal sheet and a second metal sheet, a set of waterproof grooves are formed in each of the upper side and the lower side of the inner surface of the heat dissipation opening, and the storage battery powers on the electromagnet to enable the electromagnet to have magnetism. Therefore, the ferromagnetic plate is attracted to extend into the water stop groove, namely, the water baffle fixedly connected with the ferromagnetic plate extends into the water stop groove, when the water-swelling rubber water-stop strip expands, the water-swelling rubber water-stop strip can fill a gap, facing one side of the water-swelling rubber water-stop strip, of the water-stop plate after the water-swelling rubber water-stop strip extends into the water-stop groove, so that the sealing effect is further improved, the device has remarkable waterproofness, and the device is better protected.

Description

technical field [0001] The invention relates to the technical field of power adapters, in particular to a waterproof power adapter with low loss and high heat dissipation. Background technique [0002] The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of housings, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC output; press the connection Ways can be divided into wall-mounted and desktop. It is widely used in security cameras, set-top boxes, routers, light strips, massagers and other equipment. [0003] In the existing technology, the power adapter generates heat during the working process, and the accumulation of heat in the power adapter will easily cause short circuit and other faults inside the power adapter, and the power adapter will be submerged in the water due to human misuse, caus...
