Left end connection, gap location between the inner surface of single hole magnesium pipe and the outer surface of conductive rod is equipped with magnesia powder.Inside is filled out
Single hole magnesium pipe filled with magnesia powder plays insulating effect, single hole magnesium pipe of the inside filled with magnesia powder be avoided that conductive rod with
It discharges between heating wire.
When processing electric heater unit, it is necessary to magnesia powder be filled into the inner surface and conductive rod of single hole magnesium pipe
Outer surface between gap location；At this moment make heating wire left end and single hole magnesium pipe left end it is upward, the right end of single hole magnesium pipe to
Under, gear powder device is then equipped with below single hole magnesium pipe；Then the inner surface to single hole magnesium pipe and conductive rod from top to down
Gap location filling magnesia powder between outer surface, at this moment can remain air, the magnesia in single hole magnesium pipe in single hole magnesium pipe
The compactness of powder is low；Then gear powder device is removed, while the magnesia powder in single hole magnesium pipe is made to be fixed in single hole magnesium pipe；Again
It is processed further producing final electric heater unit, air is remained in the single hole magnesium pipe in electric heater unit at this moment.When
When electric heater unit is powered, heating wire generates heat, heats the air in single hole magnesium pipe, air expansion, it may occur that explosion, it is uneasy
Entirely；With the heating wire of heat oxidation reaction can occur for the air in single hole magnesium pipe, and heating wire can be burnt, so electric heater unit
Service life it is short.
Utility model content
The purpose of the utility model is to overcome above deficiencies, provide a kind of explosion-proof electric heater unit, it can blast protection, peace
Quan Xinggao, service life are long.
A kind of explosion-proof electric heater unit, including：Heating wire, single hole magnesium pipe, conductive rod, the conducting rod of spiral, single hole magnesium
The material of pipe is magnesia, is equipped with single hole magnesium pipe in the centerline of heating wire, the centerline in the inside of single hole magnesium pipe is set
There is a conductive rod, conductive rod left end connected by the left end of conducting rod and heating wire, in the inner surface and conductive rod of single hole magnesium pipe
Gap location between outer surface is equipped with magnesia powder；At least one groove is equipped on the tube wall of the right end of single hole magnesium pipe, it is described
Groove and single hole magnesium pipe inside connect, and the groove connects single hole magnesium tube outside.
The quantity of the groove is 2, and the groove inside single hole magnesium pipe with connecting, and the groove connects
Single hole magnesium tube outside.
The beneficial effects of the utility model are：Due to：At least one groove is equipped on the tube wall of the right end of single hole magnesium pipe,
The groove inside single hole magnesium pipe with connecting, and groove connection single hole magnesium tube outside, so：In processing originally
During utility model, it is necessary to gap magnesia powder being filled between the inner surface of single hole magnesium pipe and the outer surface of conductive rod
Place；At this moment make heating wire left end and single hole magnesium pipe left end it is upward, the right end of single hole magnesium pipe is downward, then in single hole magnesium pipe
Gear powder device is arranged below；Then the gap location from top to down between the inner surface of single hole magnesium pipe and the outer surface of conductive rod is filled out
Fill magnesia powder, the air in single hole magnesium pipe can be discharged by groove outside single hole magnesium pipe, at this moment will not be remained in single hole magnesium pipe
There is an air, the compactness of the magnesia powder in single hole magnesium pipe is high；Then gear powder device is removed, while makes the oxidation in single hole magnesium pipe
Magnesium powder is fixed in single hole magnesium pipe；Further produce final the utility model；In final the utility model
Single hole magnesium pipe in will not remain air.After the utility model is powered, heating wire generates heat, will not explode, very
Safety；Because oxidation reaction, and heating wire does not occur without air, hot heating wire in the single hole magnesium pipe in the utility model
It will not burn, so the service life of the utility model is long.
In conclusion the utility model energy blast protection, safe, service life is long.

Specific embodiment
It is described in detail below in conjunction with the accompanying drawings.
A kind of explosion-proof electric heater unit, including：Heating wire 1, single hole magnesium pipe 2, conductive rod 3, the conducting rod 4 of spiral, it is single
The material of hole magnesium pipe 2 is magnesia, single hole magnesium pipe 2 is equipped in the centerline of heating wire 1, in the inside of single hole magnesium pipe 2
Conductive rod 3 is equipped at heart line, 3 left end of conductive rod is connected by conducting rod 4 with the left end of heating wire 1, in the interior table of single hole magnesium pipe 2
