Description
Technical field
The utility model relates to enamel product technical fields, and in particular to a kind of double-layer enamel product.
Background technique
Enamel is unorganic glass enamel of the blackening on metal bottom base surface.Carrying out the enamel application of slip in metal surface can be to prevent
Only metal rusting makes metal be unlikely to form oxide layer on surface when heated and can resist the erosion of various liquid.Enamel
Product safety is nontoxic, is easy to wash cleaning, can be widely used as ware and washing implement used in daily life, and
And under given conditions, the enamel application of slip is shown on metal body hardness height, high temperature resistant, wear-resisting and insulating effect etc.
Excellent performance.Enamelware has had both the intensity of metal and the performance of the magnificent appearance and resistance to chemical attack of enamel, makes enamel
Product has more extensive purposes.Existing enamel product generallys use single layer structure, when holding the higher article of temperature,
It is easy to appear hot situation, uses risk height.
Utility model content
Technical problem to be solved in the utility model is to provide one kind for the above-mentioned prior art can be heat-insulated and to protect
The double-layer enamel product of temperature.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of double-layer enamel product, feature
Be: including internal layer body and outer layer body, the outer layer body is set in that the internal layer is external, and the opening of the internal layer body, which is turned up, to be set
It is equipped with the first flange, the outer layer body opening, which is turned up, is provided with the second flange, and second flange is wrapped in described first and turns over
In side, and the edge of the second flange is connected with the inner wall of the first flange, the edge of second flange and outer layer body it is outer
Wall is connected, and then closed cavity is formed between internal layer body and outer layer body, and vacuum is arranged in the cavity.
In order to avoid the first flange edge in use because colliding with the case where warding off and getting rusty, described the
The external wall direction bending of one flange outer layers, and the marginal portion of first flange is adjacent to and is connected to the outer of the outer layer body
On wall.
Preferably, the cross section of the cavity formed between first flange bending part and the outer wall of outer layer body is in inversion
Drops.
Preferably, the arc-shaped shape in top of first flange, the edge of second flange is along first flange top
The cambered surface of portion's inner wall turns up bending to connect with being adjacent at the top of the first flange inner wall.
Steady in order to place, the bottom notch of the bottom inner layer body of the outer layer body is formed with shallow slot.
As an improvement, the bottom notch of the bottom inner layer body of the shallow slot is provided with pit.
Compared with the prior art, the advantages of the utility model are: the double-layer enamel product uses internal layer body and outer layer body
Structure, and be tightly connected by internal layer body and the flange of outer layer body opening portion, it is true to be formed between internal layer body and outer layer body
The cavity of sky setting, such double-layer enamel product in use, can be realized good heat-insulated and heat preservation effect.
Detailed description of the invention
Fig. 1 is the cross-sectional view of double-layer enamel product in the utility model embodiment.
Fig. 2 is the magnified partial view of Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As depicted in figs. 1 and 2, the double-layer enamel product in the present embodiment, requires according to product form, including corresponding form
Internal layer body 1 and outer layer body 2.When such as making double-layer ceramic cup, the internal layer body 1 and outer layer body 2 are cylindrical in shape.
Outer layer body 2 is set in outside internal layer body 1, and the opening of internal layer body 1, which is turned up, is provided with the first flange 11, and outer layer body 2 is opened
It turns up at mouthful and is provided with the second flange 21.
Second flange 21 is wrapped in the first flange 11, the bending of 11 outer layers body of the first flange, 2 outer wall direction, and the
The marginal portion of one flange 11 is adjacent on the outer wall for being welded on outer layer body 2.The outer wall of first flange 11 bending part and outer layer body 2
Between the cross section of cavity 3 that is formed in inverted drops.
The arc-shaped shape in top of first flange 11, the edge of the second flange 21 is outside the cambered surface of 11 top inner wall of the first flange
Bending is turned over to weld together with being adjacent at the top of 11 inner wall of the first flange.It is such then pass through the first flange 11 and the second flange 21
It realizes the sealed connection between internal layer body 1 and outer layer body 2, forms closed cavity 4, cavity between internal layer body 1 and outer layer body 2
Vacuum is arranged in 4.Specifically in production, need to reserve the venthole for vacuumizing in the bottom of outer layer body 2, wait vacuumize
After the completion of operation, the sealing operation of venthole is realized using the prior art, realizes the vacuum setting of cavity 4.
In order to guarantee the steady placement of the double-layer enamel product, the bottom notch of the bottom inner layer body 1 of outer layer body 2 is formed
There is shallow slot 12, and the bottom notch of the bottom inner layer body 1 of shallow slot 12 is provided with pit 121.
It, can be in the inner wall of internal layer body 1 after internal layer body 1 and outer layer body 2 weld together and carried out vacuum pumping
And application of slip operation is carried out on the outer wall of outer layer body 2.The outer of outer layer body 2 is welded on since the marginal portion of the first flange 11 is adjacent to
On wall, then 11 application of slip rear surface of the first flange is smooth, and due to the outer wall of the marginal portion of the first flange 11 and outer layer body 2 it
Between without gap, then be not in air bubble problem when the application of slip, application of slip effect is good, and can make the exquisiter beauty of product appearance.
