Abstract
The utility model discloses a kind of conic ceramic heaters in heater context, including conic ceramic cylinder, circumferentially spiral is buried equipped with electric heating wire in conic ceramic cylinder, the periphery of conic ceramic cylinder is arranged with protective metal shell, the bottom of conic ceramic cylinder is through cover closure, the utility model by heating cylinder by being designed to pyramidal structure, only need a piece electric heating wire of setting that gradient-heated can be realized, thus greatly reduce cost, production efficiency is improved, can be used in the heating of partial gradient distribution.
Description
Technical field
The present invention relates to a kind of heater, more particularly to a kind of ceramic heater.
Background technology
Ceramic heater is a kind of ceramic electric heating plate electrified regulation equipment, since ceramic material used is in operating temperature
There are down good electrical insulation properties, therefore surface is not charged, and leakage current is small when work, safe and reliable, therefore, pottery
The use of porcelain heater is increasingly popular.Existing tubular ceramic heater is generally internally provided with multigroup electrical heating in ceramics
Silk, while it is working, as long as heater strip is opened, then for some feature requirement heating environments, such as local heating amplitude
It is required that unbalanced equipment, then need the power for controlling different heating silk, this allows for controlling relatively complicated, processing inconvenience.
Invention content
Simple in structure the object of the present invention is to provide a kind of conic ceramic heater, easy to control, production efficiency is high.
The object of the present invention is achieved like this：A kind of conic ceramic heater, including conic ceramic cylinder, the taper
Circumferentially spiral is buried equipped with electric heating wire in ceramic cylinder, and the periphery of the conic ceramic cylinder is arranged with protective metal shell, described
The bottom of conic ceramic cylinder is through cover closure.
When the present invention works, it need to only be powered to electric heating wire, since structure of the invention is conical shell structure, by
Heating region heat distribution under above is distribution gradient, this just meets requirement in the prior art, it is no longer necessary to right
Local electrical resistance silk is controlled respectively.Compared with prior art, the beneficial effects of the present invention are, the present invention by by cartridge heater
Body is designed to pyramidal structure, it is only necessary to an electric heating wire be arranged, gradient-heated can be realized, thus greatly reduce cost, carry
High production efficiency.The present invention can be used in the heating of partial gradient distribution.
In order to enhance heating effect of the present invention, insulating layer is filled between the conic ceramic cylinder and protective metal shell.
In order to enhance the seal of the present invention, dust cover, the cover center are provided at the top of the conic ceramic cylinder
Offer opening.
In order to further enhance the seal of the present invention, the dust cover processes camber.Arcuate structure to fall anti-
Sundries on dust hood slides in time.
Description of the drawings
Fig. 1 schematic structural views of the invention.
Wherein, 1 dust cover, 1a openings, 2 ceramic cylinders, 3 electric heating wires, 4 insulating layers, 5 protective metal shells, 6 cover boards.
Specific implementation mode
A kind of conic ceramic heater as shown in Figure 1, including conic ceramic cylinder 2, edge in the conic ceramic cylinder 2
Periphery spiral is buried equipped with electric heating wire 3, and the periphery of the conic ceramic cylinder 2 is arranged with protective metal shell 5, the conic ceramic cylinder
The bottom of body 2 is closed through cover board 6, and insulating layer 4, the taper pottery are filled between the conic ceramic cylinder 2 and protective metal shell 5
The top of porcelain cylinder 2 is provided with dust cover 1, and the cover center offers opening 1a, and the dust cover processes camber.
When the present invention works, it need to only be powered to electric heating wire 3, since structure of the invention is 2 structure of conical shell,
Heating region heat distribution from top to bottom is distribution gradient, this just meets requirement in the prior art, it is no longer necessary to
Local resistance wire 3 is controlled respectively.
The invention is not limited in above-described embodiments, on the basis of technical solution disclosed by the invention, the skill of this field
For art personnel according to disclosed technology contents, one can be made to some of which technical characteristic by not needing performing creative labour
A little to replace and deform, these are replaced and deformation is within the scope of the invention.
