Abstract
The utility model relates to a casing tube type electric heating pipe and the utility model is mainly characterized in that an outer tube is used for sealing an electric heating inner tube to make the electric heating inner tube separated from shower water for avoiding the corrosion of showering by electric heating to cause human bodies to have electric shock; the sealing structure, connecting structure, etc. that an insulator is used for connecting and sealing the electric heating tube and an outer casing tube further ensures the safety of using the electric heating pipe of an electric heating shower. The casing tube type electric heating pipe is especially used for electric heating showers, and besides, the utility model can also be used for similar conditions, such as electric water heaters.
Description
The utility model relates to a kind of insulation sleeve structure electrothermal tube.
Electric heating shower in the past because electrothermal tube directly contacts with shower water, in case fault takes place, causes the human electric shock easily in water tank.
First purpose of the present utility model is to make electrothermal tube not contact with shower water, electrothermal tube with indirect mode with heat conduction, the heating shower water.
Second purpose of the present utility model is when guaranteeing electrothermal tube chance failure, can not cause getting an electric shock because of the circuit bypass.
First purpose of the present utility model is achieved in that a kind of bushing type electrothermal tube, it is characterized in that: U-shaped, interior dress be insulated the electrothermal tube (1) of heating wire of powder insulation sealed, be sleeved in the overcoat metal tube (2) that fills up insulating powder.Because electrothermal tube (1) is by outer tube (2) sealing, thus can not contact with the water in the water tank, thus exempted it to be corroded and worn out the danger of electric leakage by shower water.
Second purpose of the present utility model is achieved in that pipe (1) and manages the connector (3) that (2) connect as one and replace with insulator, like this, even pipe (1) is punctured by unexpected, thereby electric current can not be transmitted to outer tube (2) through connector (3) along pipe (1) metal surface cause the human electric shock.On the interior or outer wall of pipe (2), establish insulating film layer (4),, also can not cause the human electric shock immediately even the interior insulating powder of pipe (2) is merged by high temperature and conducts electricity like this.
The utility model is owing to adopted pipe (1), pipe (2) so mutual Sealed casing pipe structure has separated electrothermal tube (1) contacts with the direct of water, avoided electrothermal tube (1) to be corroded and caused Danger Electric shock risk by shower water, again owing to adopted insulated connecting piece between connection, sealed tube (1), the pipe (2), or the method that insulating film layer (4) is set on pipe (2) inner-outer wall further prevents the human electric shock.The utility model is specially adapted to electric heating shower.
Fig. 1, a kind of electrothermal tube structure schematic diagram of the present utility model.
Embodiment:
See that Fig. 1, pipe (1), pipe (2) are metal tube,, also constitute between two pipes electrothermic wire insulation by insulating powder (non-conductive, but the metal oxide powder of good heat conductivity) in the pipe (1) by same insulating powder.The connector (3) that will manage (1), pipe (2) sealing, connects is an insulating ceramics spare.Inwall at pipe (2) scribbles high-temperature insulation coating.
Claims (3)
1, a kind of bushing type electrothermal tube is characterized in that: U-shaped, interior dress be insulated the electrothermal tube (1) of heating wire of powder insulation sealed, be sleeved in the overcoat metal tube (2) that fills up insulating powder.
2, electrothermal tube according to claim 1 is characterized in that: will manage (1) and the connector (3) that connects as one of pipe (2) is an insulator.
3, electrothermal tube according to claim 1 and 2 is characterized in that: establish insulating film layer (4) on the interior or outer wall of pipe (2)
