Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a double-layer anti-scalding kettle. Background Technology

[0002] Currently, there are two types of double-walled anti-scalding kettles on the market: 1. Double-walled glass: The advantage is that the fully transparent design combines aesthetic value and a high-end feel, making it easy to directly observe the state of limescale inside the kettle; however, the disadvantage is that the complex process of high borosilicate glass leads to a significant increase in manufacturing costs, the kettle body is relatively heavy, and the glass material is prone to breakage in the event of an impact. 2. Composite structure (such as plastic outer shell + stainless steel inner liner): The advantage is that the lightweight design improves ease of use; however, the disadvantage is that due to the characteristics of stainless steel, it cannot achieve the transparency and high-end feel of glass, and the texture is weaker.

[0003] In summary, the high cost and weight of double-walled glass water bottles in existing technologies contradict the low light transmittance and insufficient texture of composite structures, resulting in a lack of products in the market that simultaneously meet the four requirements of high transparency, excellent tactile feel, lightweight and low cost. Utility Model Content

[0004] Based on this, in order to address the conflicting issues of high cost and weight of double-walled glass kettles versus low light transmittance and insufficient texture of composite structures in existing technologies, this utility model provides a double-walled anti-scalding kettle, the specific technical solution of which is as follows:

[0005] A double-layer anti-scalding kettle includes a spout, an outer shell, an inner liner, a first heat insulation component, and a second heat insulation component; the first heat insulation component is sleeved on the inner liner, and the spout clamps the first heat insulation component and the outer shell; the outer shell is inserted into the second heat insulation component, and the second heat insulation component abuts against the inner liner; a first sealing space is formed between the outer shell, the inner liner, the first heat insulation component, and the second heat insulation component.

[0006] The aforementioned double-walled anti-scalding kettle, through the inclusion of a first heat insulation component and a second heat insulation component, isolates the inner liner from the outer shell, preventing direct heat transfer from the inner liner to the outer shell. An air layer within the first sealed space forms a highly efficient heat-insulating cavity, enhancing heat retention. The double-layered high-transparency design of the outer shell and inner liner allows for 360° water level monitoring and scale observation, overcoming the limitation of traditional stainless steel inner liners being opaque. The first and second heat insulation components enclose and secure the inner liner, dispersing external impact stress and reducing the risk of liner breakage. The plug-in nested structure simplifies the production process, allowing for standardized mass production of components and reducing manufacturing costs compared to pure double-walled glass kettles.

[0007] Furthermore, the spout includes a spout portion and a first fixing portion and a second fixing portion both disposed on the spout portion; the first fixing portion and the second fixing portion cooperate to clamp the first heat insulation component and the outer shell.

[0008] Furthermore, the outer contours of both the first fixing part and the second fixing part are arranged in annular shape, and a first space is formed between the first fixing part and the second fixing part for the insertion of the first heat insulation component and the outer shell.

[0009] Furthermore, the first heat insulation component includes a fixing ring and a first sealing ring, both with a U-shaped cross-section; the first sealing ring is sleeved on the fixing ring, and the fixing ring is sleeved on the inner liner.

[0010] Furthermore, the first sealing ring is provided with multiple layers of first sealing edges and second sealing edges, the first sealing edges sealingly abutting against the second fixing part; the second sealing edges cooperate with the first fixing part to seal and clamp the outer shell.

[0011] Furthermore, the second heat insulation component includes a kettle bottom and a second sealing ring sleeved on the kettle bottom; the outer shell is inserted into the second sealing ring; the bottom of the inner liner is provided with a slot portion, and the slot portion is provided with an extension portion; the second sealing ring is provided with a first insertion portion and a heat insulation portion; the first insertion portion is inserted into the slot portion, and the kettle bottom, the heat insulation portion and the extension portion abut against each other in sequence.

[0012] Furthermore, the outer shell is made of transparent plastic, and the inner liner is made of transparent glass. Attached Figure Description

[0023] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0024] like Figures 1-4 As shown, a double-layer anti-scalding kettle according to one embodiment of the present invention includes a spout 1, an outer shell 2, an inner liner 3, a first heat insulation component 4, and a second heat insulation component 5; the first heat insulation component 4 is sleeved on the inner liner 3, and the spout 1 clamps the first heat insulation component 4 and the outer shell 2; the outer shell 2 is inserted into the second heat insulation component 5, and the second heat insulation component 5 abuts against the inner liner 3; a first sealing space 6 is formed between the outer shell 2, the inner liner 3, the first heat insulation component 4, and the second heat insulation component 5.

[0025] The aforementioned double-walled anti-scalding kettle, by incorporating a first heat insulation component 4 and a second heat insulation component 5, isolates the inner liner 3 from the outer shell 2, preventing the heat from the inner liner 3 from being directly transferred to the outer shell 2. The air layer within the first sealed space 6 forms a highly efficient heat-insulating cavity, enhancing the heat retention effect. The double-walled high-transparency design of the outer shell 2 and inner liner 3 enables 360° water level monitoring and scale observation without blind spots, overcoming the limitation of traditional stainless steel inner liners being opaque. The first and second heat insulation components 4 enclose and fix the inner liner 3, dispersing external impact stress and reducing the risk of breakage. The plug-in nested structure simplifies the production process, allowing for standardized mass production of components and reducing manufacturing costs compared to pure double-walled glass kettles.

[0026] like Figures 1-3 As shown, in one embodiment, the spout 1 includes a spout portion 11 and a first fixing portion 12 and a second fixing portion 13 both disposed on the spout portion 11; the first fixing portion 12 and the second fixing portion 13 cooperate to clamp the first heat insulation component 4 and the outer shell 2; the outer contours of the first fixing portion 12 and the second fixing portion 13 are both annular, and a first space 7 is formed between the first fixing portion 12 and the second fixing portion 13 for inserting the first heat insulation component 4 and the outer shell 2; the first heat insulation component 4 includes a fixing ring 41 and a first sealing ring 42, both with a U-shaped cross-section; the first sealing ring 42 is sleeved on the fixing ring 41, and the fixing ring 41 is sleeved on the inner liner 3; the first sealing ring 42 is provided with multiple layers of first sealing edges 43 and second sealing edges 44, the first sealing edges 43 sealingly abutting against the second fixing portion 13; the second sealing edges 44 cooperate with the first fixing portion 12 to seal and clamp the outer shell 2; specifically, the fixing ring 41 is made of stainless steel, and the first sealing ring 42 is made of silicone. Thus, with both the first fixing part 12 and the second fixing part 13 being annular, a ring-shaped clamping space (first space 7) is formed. By symmetrically clamping the outer shell 2 and the heat insulation component, uniform force distribution is achieved. The annular contour design avoids local stress concentration and prevents the outer shell from cracking due to compression. At the same time, the annular structure adapts to the circular kettle body, ensuring coaxiality and avoiding sealing failure caused by assembly misalignment. Compared with single-point fixing, this design improves vibration resistance and reduces the risk of component loosening when pouring liquid. The fixing ring 41 provides a skeleton-like support for the first sealing ring 42; the first sealing edge 43 abuts against the second fixing part 13, isolating the spout 1 from the external environment and preventing steam leakage; the second sealing edge 44 clamps the outer shell 2 with the first fixing part 12, forming a radial compression seal to compensate for manufacturing tolerances.

[0027] like Figures 1-4As shown, in one embodiment, the second heat insulation component 5 includes a kettle bottom 51 and a second sealing ring 52 fitted onto the kettle bottom 51; the outer shell 2 is inserted into the second sealing ring 52; the bottom of the inner liner 3 is provided with a slot portion 8, and the slot portion 8 is provided with an extension portion 9; the second sealing ring 52 is provided with a first insertion portion 20 and a heat insulation portion 10; the first insertion portion 20 is inserted into the slot portion 8, and the kettle bottom 51, the heat insulation portion 10, and the extension portion 9 abut against each other in sequence; specifically, the second sealing ring 52 is made of silicone. Thus, the engagement of the slot portion 8 and the first insertion portion 20 forms a first physical isolation layer, reducing the direct conduction of heat from the kettle bottom 51 to the outer shell 2 through the metal components; the abutment of the heat insulation portion 10 and the extension portion 9, with the silicone heat insulation portion 10 acting as a second barrier, further blocks residual heat using its low thermal conductivity; the insertion design of the slot portion 8 and the first insertion portion 20 provides a mechanical interlocking function, preventing the component from shifting during vibration or tilting. The high elasticity of silicone can absorb the stress caused by assembly tolerances and thermal expansion and contraction, avoiding seal failure due to deformation; the plug-in structure reduces assembly difficulty (such as eliminating the need for welding or threaded fastening), improving the efficiency of automated assembly.

[0028] In one embodiment, the outer shell is made of plastic, and the inner liner is made of glass. This double-layered, high-transparency design of the outer shell and inner liner allows for 360° all-around monitoring of water level and observation of scale buildup.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
