The utility model discloses an useful technological effect is: be provided with in the low pressure safety type electric water heater and trun into 220V to 12V the reducing transformer is kept apart in 36V's interchange, for temperature controller and low -voltage cermet heating device provide the power, to install in the thermal -insulated material cavity of preserving moisture of electric water heater body one end, and does the effective isolation 220V commercial power make temperature controller and low -voltage cermet heating device only connect 12V 36V safe voltage stops the potential safety hazard.
Description
Technical field
This utility model relates to a kind of electric heater, particularly relates to a kind of low voltage safety electric heater.
Background technology
Existing electric heater is all direct 220V city electrical heating, inevitable after using certain time
There is the potential safety hazard of electric leakage in ground, is easily caused fire incident or personal injury etc., can not expire
The requirement of foot people.
Utility model content
The purpose of this utility model is to provide a kind of low voltage safety electric heater, solves existing skill
The shortcoming that art exists.
This utility model adopts the following technical scheme that realization:
A kind of low voltage safety electric heater, including electric heater body, described electric heater body
Inner bag and outer gallbladder by nested structure are constituted, and are filled with insulating between inside and outside gallbladder, its
It is characterised by, is also equipped with electrically insulating reducing transformer, described electric isolution reducing transformer between inside and outside gallbladder
It is connected with low pressure metal ceramic heater by low tension connecting line.
Further, electric heater body is provided with entery and delivery port, temperature controller and use
In the installing port installing low pressure metal ceramic heater.
Further, described electric isolator is the exchange isolated buck device that 220V turns 12V～26V.
Advantageous Effects of the present utility model is: be provided with in low voltage safety electric heater
220V is transferred the exchange isolated buck device of 12V-36V to, for temperature controller and low-voltage metal
Ceramic heat device provides power supply, is installed on the heat insulation moisturizing material cavity of electric heater body one end
In, it is effectively isolated 220V civil power, makes temperature controller and low-voltage ceramic metal heater element only connect
Connect 12V-36V safe voltage, thus stop potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the structure chart of low voltage safety electric heater.
Detailed description of the invention
By the following description to embodiment, will more contribute to public understanding this utility model, but
Specific embodiment given by applicant can't be considered as this utility model technical side
The restriction of case, any definition to parts or technical characteristic is changed and/or overall structure is made shape
Formula and immaterial conversion is regarded as the protection domain that the technical solution of the utility model is limited.
Low voltage safety electric heater as shown in Figure 1, including electric heater body 1, electric heater
Body 1 is made up of inner bag and the outer gallbladder of nested structure, is additionally provided with installation in electric heater body 1
The cavity of temperature controller, is filled with insulating between inside and outside gallbladder, inside and outside gallbladder it
Between be also equipped with electrically insulating reducing transformer 2, electric isolution reducing transformer 2 is by low tension connecting line 6 and low pressure
Ceramic metal heater 7 is connected, electric heater body is provided with water inlet 3, outlet 4,
Temperature controller 5 and for installing the installing port of low pressure metal ceramic heater, temperature controller 5
And low-voltage ceramic metal heater 7 provides power supply by low tension connecting line 6, it is installed on electric heating
In the heat insulation moisturizing material cavity of hydrophone body one end, it is effectively isolated 220V civil power, makes temperature control
Device 5 and low-voltage ceramic metal heater element 7 connect 12V-36V safe voltage, thus stop
Potential safety hazard.In the present embodiment, the voltage of low-voltage ceramic metal heater 7 is 6V-36V,
Monomer electrical power is carried out also by low tension connecting line 6 at 30-100W, multiple heaters of setting
Connection connects.Ceramic metal heater is that the uniform heater of a kind of High Efficiency Thermal branch, thermal conductance are splendid
Metal alloy, it is ensured that hot-face temperature is uniform, eliminates focus and the cold spot of equipment.As can be closed
It is in raw-material quasiconductor that spun gold casts in quartz glass.Have high temperature resistant (up to 1200 degree),
Anticorrosion, wear-resisting feature attractive in appearance.Be widely used in high temperature heating stove, semiconducter engineering, glass,
In pottery and wire work.
Ceramic metal heater can also be made on the basis of above-described embodiment and further changing
Enter: bury heating resistor underground in the inside of ceramic metal heater, form a heating core, at gold
Belonging to the outer surface welding electrode of ceramic heater, electrode is positioned at the both sides of heating part, heating core appearance
Face is provided with silicon dioxide layer, is provided with fever tablet, fever tablet and electricity between heating core and silicon dioxide layer
Pole is connected, and fever tablet is u-shaped, and is uniformly covered with heating core outer surface.Technology after improvement
Effect is to improve the programming rate of ceramic metal heater, is covered with heating on heating core surface simultaneously
Sheet, further increases the programming rate of ceramic heater, and the course of processing is simply efficient, heat transfer speed
Degree is fast, and service life is long.
Certainly, this utility model can also have other various embodiments, without departing substantially from this utility model
In the case of spirit and essence thereof, those of ordinary skill in the art can do according to this utility model
Go out various corresponding change and deformation, but these change accordingly and deformation all should belong to this practicality newly
Scope of the claims appended by type.
