A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
The every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Embodiment one
Fig. 1 is the structural schematic diagram for the electric kettle that the embodiment of the present invention one provides.As shown in Figure 1, the present embodiment is provided
Electric kettle, including heating element 1 and the glass bottle body 2 for holding hot liquid to be added, heating element 1 is arranged in glass bottle body
2 bottom wall outer, and liquid thermal conductivity media is filled in the gap between heating element 1 and the bottom wall 2a of glass bottle body 2.
Wherein, glass bottle body 2 is usually an autonomous container that can be used for holding water or other hot liquids to be added, and
Heating element 1 is generally arranged at the bottom of glass bottle body 2, and on the outside of the bottom wall 2a of glass bottle body 2, such heating element 1
When being heated to glass bottle body 2, the liquid such as water in glass bottle body 2 and heating element 1 are completely isolated, can improve when heated
Safety, avoid leaky.In order to enable the heat that heating element 1 is sent out to be conducted efficiently to glass bottle body 2, and
Liquid in glass bottle body 2 is heated, is filled in the gap between the bottom wall 2a and heating element 1 of glass bottle body 2
Liquid thermal conductivity media 3.Liquid thermal conductivity media 3 has higher heat-transfer rate, when the bottom of liquid thermal conductivity media 3 and glass bottle body 2
It, can be rapidly by the heat transfer on heating element 1 to the bottom of glass bottle body 2 when wall 2a and heating element 1 are kept in contact
Wall 2a efficiently, quickly heats to realize.In general, heating element 1 can be heat-generating disc.
Since liquid thermal conductivity media 3 has mobility, so when liquid thermal conductivity media 3 is filled in the bottom wall of glass bottle body 2
When in the gap between 2a and heating element 1, can be uniformly filled in the gap, and with the bottom wall 2a of glass bottle body 2 and add
The surface of thermal element 1 keeps coming into full contact with, phenomena such as without gap or stomata.Heating can be effectively ensured in this way
There is good heat transfer between element 1 and the bottom wall 2a of glass bottle body 2, ensure that electric kettle has the higher efficiency of heating surface.
In this way, due to the presence of liquid thermal conductivity media 3, heating element 1, which is formed by heat, to be situated between by liquid thermal conductivity
Matter 3 and quickly and expeditiously pass to glass bottle body 2, allow glass bottle body 2 to heat the liquid wherein held so that
Electric kettle has preferable heating properties, and heat loss is smaller.
In order to provide faster thermal conduction rate and preferable mobility simultaneously, liquid thermal conductivity media 3 generally can be
Conduction oil.Conduction oil is also heat-transfer oil, is a kind of oil product of better heat stability for indirect transfer heat.Due to conduction oil

Fluid media (medium), do not limit herein.
Wherein, in order to ensure that the heat conduction efficiency of liquid thermal conductivity media 3 is higher, the bottom wall of heating element 1 and glass bottle body 2
The liquid thermal conductivity media 3 should be full of in gap between 2a.At this point, opposite between heating element 1 and the bottom wall 2a of glass bottle body 2
Part there is the liquid thermal conductivity media 3, and liquid thermal conductivity media 3 and the surface of heating element 1 and the bottom of glass bottle body 2
Wall 2a keeps coming into full contact with, and heat-conducting area equivalent in this way is larger, it is ensured that higher heat conduction velocity and higher heat pass
Lead efficiency.
In addition, in order to ensure heating uniformity when heated, each position of the bottom wall 2a of glass bottle body 2 and heating unit
Spacing between part 1 should keep equal or roughly equal, each position and heating element on the bottom wall 2a of such glass bottle body 2
The thickness of liquid thermal conductivity media 3 between 1 generally remains equal, thus the length of heat conduction path can also approach unanimously, can
So that each positions bottom wall 2a of glass bottle body 2 are heated more uniformly, the uniformity and consistency of heating are preferable.In general,

In general, the top in space or container that casing 11 and heating element 1 are surrounded can be hatch frame or envelope
Close structure.For example, spacing is kept between the top and glass bottle body 2 of casing 11, to make 1 common structure of casing 11 and heating element
At the container of an open top.In this way be convenient for liquid thermal conductivity media 3 filling and replacement, while liquid thermal conductivity media 3 by
When thermal expansion, liquid thermal conductivity media 3 will not be formed and be hindered.
In general, for reinforcement structure leakproofness, casing 11 and heating element 1 are usually an integral structure.At this point it is possible to
Keep the edge of heating element 1 protruding upward, and forms the casing 11 being disposed around on the outside of the bottom wall 2a of glass bottle body 2.At this point, due to
Gap is simultaneously not present in casing 11 and heating element 1, it is possible to effectively avoid liquid heating medium 3 from casing and heating element it
Between gap leak out.In this way, casing and heating element are an entirety, with good leakproofness, it is possible to prevente effectively from liquid
Body heat-conducting medium 3 leaks out.
It is well contacted to ensure to have between liquid thermal conductivity media 3 and the bottom wall 2a of glass bottle body 2, casing 11 and heating
The liquid level of liquid thermal conductivity media 3 in the space that element 1 surrounds jointly is generally greater than where the bottom wall 2a of glass bottle body 2
Highly.In this way since the liquid level of liquid thermal conductivity media 3 is higher, it is ensured that the bottom wall 2a of glass bottle body 2 is effectively immersed liquid
In heat-conducting medium 3, without to deposit between liquid thermal conductivity media 3 and glass bottle body 2 because the amount of liquid thermal conductivity media 3 is inadequate
In gap.
In the present embodiment, electric kettle includes heating element and the glass bottle body for holding hot liquid to be added, heating element
Bottom wall outer in glass bottle body is set, and is filled with liquid thermal conductivity in the gap between heating element and the bottom wall of glass bottle body
Medium.Liquid thermal conductivity media can keep coming into full contact with the bottom wall of glass bottle body and the surface of heating element in this way, and
Phenomena such as being not in gap or stomata, can be effectively ensured between heating element and the bottom wall of glass bottle body with good
Heat transfer ensures that electric kettle has the higher efficiency of heating surface.
