Description
Technical field
The utility model relates to a kind of new liquid electric heater.
Background technology
The liquid heater of prior art is that resistance wire is placed in metal bar mostly, by metal bar, directly with water, contacted, due in the process of heating up water, incrustation scale is very easily adhered on the metal bar surface, is difficult to cleaning, and can make electrothermal tube burn out, and levy poorly sealedly at interface, easily exist the electric leakage situation to occur, safety in utilization is not high, and can make water inlet in metal bar, affect the efficiency of heating surface.
Summary of the invention
The purpose of this utility model is to provide a kind of new liquid electric heater of simple in structure, good airproof performance.
The technical scheme that realizes the utility model purpose is a kind of new liquid electric heater, the heat conduction shell that comprises an end opening, be arranged on the heating wire in heat conduction shell, be arranged on the protective cover of heat conduction shell opening part, be provided with seal connector between described heat conduction shell and described protective cover, the two ends of described seal connector are respectively equipped with slot, described heat conduction shell and protective cover are plugged on respectively in described slot, in described slot is provided with, exterior seal ring, described inner seal ring is arranged between described slot inwall and described heat conduction shell or protective cover, described exterior seal ring is arranged between described slot outer wall and described heat conduction shell or protective cover, described protective cover is provided with sewage draining exit.
Described heat conduction shell is single spiral cast.
The utlity model has positive effect: of the present utility model simple in structure, be provided with seal connector between heat conduction shell and protective cover, and the two ends of seal connector are respectively equipped with slot, and be provided with inside and outside sealing ring in slot, good seal performance, when electric heating, the leakproof good electrical property, and effectively raise the efficiency of heating surface.
