Embodiment

[0024] like figure 1 As shown, a leakage prevention structure includes a housing 1, an upper sealing cover 2, an upper end cover 3, a lower sealing cover 4, a lower end cover 5, an audible and visual alarm 6 and a temperature sensor 7; wherein the housing 1 is Stainless steel seamless pipe body, the inner wall of the shell 1 is provided with a corrosion-resistant layer 12, and the outer wall is covered with an insulating layer 11 and a heat insulating layer 13 in turn; the shell 1 is also provided with 9 rubber hoses, which are connected end to end And in series to form a 400mm folding reciprocating flow channel 8, such as figure 2 As shown, ensure that the water resistance is large enough to actively prevent environmental leakage.

[0025] Specifically, the insulating layer 11 is a silicone rubber insulating layer with a thickness of 3mm-5mm; the corrosion-resistant layer 12 is a plastic layer 122 and a rubber buffer layer 121 covered from the inside to the outside, and the...

Abstract

The invention discloses an electricity leakage prevention structure, and relates to the field of electric appliance control. The electricity leakage prevention structure comprises a shell, an upper seal cover, an upper end cover, a lower seal cover, a lower end cover, a temperature sensor, an audible and visual alarm and a current detection chip. The shell is a stainless steel seamless pipe body;an anti-corrosion layer is arranged on the inner wall of the shell; an insulating layer and a thermal insulation layer are sequentially wrapped on the outer wall of the shell; and a 400 mm folded reciprocating flow channel formed by connecting 9 rubber hoses end to end in series in a communicating manner is further arranged in the shell, it is ensured that the water resistance is large enough, andtherefore environment electricity leakage is initiatively prevented. Because the upper end cover and the lower end cove can each be directly formed through injection molding and are then fastened andconnected through bolts, assembly is easy, the structure is compact, production and machining are easy, and the manufacture cost is low. The temperature can be detected in real time through the temperature sensor with a liquid crystal display screen and a waterproof probe. If the current detection chip detects the electricity leakage situation, a light-emitting rotating LED warning light of the audible and visual alarm can make alarm sounds, and the safety warning effect is achieved.

Description

technical field [0001] The invention relates to the field of electric appliance control, in particular to an electric leakage prevention structure of an electric heater. Background technique [0002] With the continuous improvement of people's living standards, residents' demand for electrical products is increasing day by day, and accidents related to electricity are also increasing, and there are even many electric shock casualties. The reason is that many of these accidents are caused by the leakage of electric heaters. Due to the adjustment of safety policies and the increasing awareness of personal safety protection, while energy saving has become the theme of electric heaters, leakage prevention has become the eternal development of electric water heater technology. theme. [0003] There are two main reasons for the leakage of the electric heater: the electric heater itself leaks electricity, because the heating element of the electric heater, the electric heating tub...
