Description
Technical field
This utility model relates to electric heater technical field, particularly relates to the electric heating of a kind of effective reduction inner bag protective current
Hydrophone.
Background technology
Electric heater is the most conventional a kind of household electrical appliance, generally includes: inner bag, the electrical heating dress being arranged in inner bag
Put and magnesium rod.The electric heater of storage-type electric water heater in the market is installed and is directly conducted with inner bag, this peace
Maximum shortcoming existing for assembling structure is that electric heater belongs to bare metal, at magnesium rod and inner bag generation galvanic interaction
Time, the exposed large stretch of metal out of electric heater can accelerate reaction, thus the current value produced is very big, shortens the use longevity of magnesium rod
Life.
On electric heater, the size of inner bag protective current value imply that the speed of magnesium rod depletion rate, and current value is the biggest,
The depletion rate of magnesium rod is the fastest, and current value is the least, and magnesium rod depletion rate is the least.Magnesium rod depletion rate the most also imply that inner bag is rotten
The speed of erosion slows down, and the life-span of inner bag will be extended, then the protective current value reducing inner bag extends the inner bag life-span by being
One big feasible scheme.At present, in electric heater industry, modal method is: 1) improve the enamel effect of inner bag.2) at electricity
Resistance is increased, one as open in the Chinese utility model patent of Publication No. CN201652807U between heater and magnesium rod
Corrosion-prevention device for inner container of electric water heater, including inner bag connection wire rod, resistance, magnesium rod connecting rod, magnesium rod.The negative pole end of resistance is with interior
Gallbladder connection wire rod connects；The positive terminal of resistance is connected with magnesium rod connecting filament.The connection end of resistance, resistance and inner bag connection wire rod,
Resistance is all coated in plastic material with the connection end of magnesium rod connecting rod.Though this structure can play the anti-corrosion to inner container of electric water heater
Effect, but installing/dismounting is inconvenient, and resistance is placed in inner bag, have impact on the normal service life of resistance.
Summary of the invention
For problems of the prior art, the purpose of this utility model is to provide a kind of simple, efficiently, it is simple to tear open
Unload and install and can effectively reduce the electric heater of inner bag protective current.
For reaching object above, this utility model adopts the following technical scheme that.
A kind of electric heater of effective reduction inner bag protective current, including: inner bag, the magnesium being arranged on inner bag rod, electricity add
Hot device, described electric heater is arranged on inner bag gallbladder mouth by electric heater flange, is provided with between electric heater flange and inner bag
Liner mouth sealing ring；It is characterized in that, it also includes that resistance, described resistance are connected between inner bag and electric heater；Described gallbladder mouth
Sealing ring makes only to be turned on by resistance between electric heater and inner bag by fully wrapped around for the junction of electric heater flange.
As with improvement, described in state liner mouth sealing ring and include: sealing and insulation division, described sealing is horn-like opening
Mouthful, described insulation division be stretch out along flare openings after the caulking groove of fold inward again；The sidepiece of electric heater flange is stuck in
In flare openings, the outward flange of electric heater flange is wrapped up by caulking groove.
As with improvement, described magnesium rod is arranged on inner bag by drain plug.
As with improvement, described electric heater flange is fixed with inner bag by mounting flange, bolt, concrete fixed structure
For: by a nut check after screw bolt passes inner bag, electric heater flange, mounting flange.
As with improvement, inner bag is additionally provided with bolt installation position, bolt installation position offers installing hole.
As with improvement, on bolt, set has the spring washer corresponding with nut.
The beneficial effects of the utility model are:
One, by the structure of liner mouth sealing ring is improved, liner mouth sealing ring is made can to play sealing function, moreover it is possible to rise
To insulating effect, when forming protective current between magnesium rod and inner bag, because electric heater is insulated so that it is protective current drops significantly
Low, thus reduce the depletion rate of magnesium rod, extend the service life of inner bag.
Two, the shape owing to being only liner mouth sealing ring is inconsistent with conventional art, it is achieved method is simple, it is easy to dismantles and pacifies
Dress.

Detailed description of the invention
It is more fully understood that essence of the present utility model for convenience of those skilled in the art, new to this practicality below in conjunction with the accompanying drawings
The detailed description of the invention of type is described in detail.
As Figure 1-Figure 4, the electric heater of a kind of effective reduction inner bag protective current, including: inner bag 1, in being arranged on
Magnesium rod 2 on gallbladder 1, electric heater 3, described electric heater 3 is arranged on inner bag 1, at electric heater by electric heater flange 4
Liner mouth sealing ring 5 it is provided with between flange 4 and inner bag 1；It is characterized in that, it also includes resistance 6, and described resistance 6 is by wire 11
It is connected between inner bag 1 and electric heater 3；Described liner mouth sealing ring 5 makes electricity by fully wrapped around for the junction of electric heater flange 4
Only turned on by resistance 6 between heater 3 and inner bag 1.
Wherein, described magnesium rod 2 is arranged on inner bag 1 by drain plug 7.Described electric heater flange 4 passes through mounting flange
8, bolt 9 is fixed with inner bag 1, and concrete fixed structure is: bolt 8 sequentially passes through inner bag 1, electric heater flange 4, mounting flange 8
Locked by a nut 10 afterwards, make electric heater flange 4 be mounted flange 8 and be pressed on the gallbladder mouth of inner bag 1.For ease of realizing bolt 9
With the installation of inner bag 1, inner bag 1 is additionally provided with bolt installation position, bolt installation position offers installing hole.For improving fastening
Effect, on bolt 9, set has the spring washer corresponding with nut 10.
Described liner mouth sealing ring 5 includes: sealing 5-1 and insulation division 5-2, and described sealing 5-1 is flare openings, institute
State insulation division 5-2 be stretch out along flare openings after the caulking groove of fold inward again.During assembling, the side of electric heater flange 4
Portion 4-1 is stuck in interior and electric heater flange 4 the outward flange 4-2 of flare openings and is wrapped up by caulking groove, to realize electric heater flange
4 junctions completely insulated.Described resistance 6 is connected with electric heater flange 4 and inner bag 1, to realize mounting flange more than 8 electrical heating
Conducting between device 3.
During real work, magnesium rod drain plug inner bag bolt and nut mounting flange resistance electric heater
It is formed for a complete galvanic element loop between water magnesium rod, under the effect of resistance 6, makes the guarantor that whole electric heater is final
