Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a kettle and an electric kettle. Background Technology

[0002] Currently, commercially available glass electric kettles and health-preserving kettles generally use a single-layer body structure, which poses a risk of breakage and burns. To improve this, the industry typically adopts a double-layer structure design, which adds a plastic / metal protective layer to the outside of the glass inner liner to achieve heat insulation.

[0003] Taking Chinese utility model patent CN206102405U as an example, it discloses a double-layer glass electric kettle, including a glass kettle body, a heat-insulating outer shell, a kettle handle, a heating plate, and a kettle bottom cover. The heat-insulating outer shell is installed on the outer surface of the glass kettle body. The lower part of the kettle body is concave below the spout, forming a concave lower part of the kettle body. The heat-insulating outer shell can be installed on the concave part of the kettle body below the spout. The concave position below the spout can be any position from which the concave section begins, and the minimum concave size allows the top of the heat-insulating outer shell to fit and fix with the top of the concave section of the glass kettle body. Although this design achieves heat insulation and anti-scalding functions, it has significant manufacturing defects: the upper stop of the heat-insulating outer shell is fixed entirely by an integral annular protrusion on the outer wall of the glass kettle body. This special structure leads to increased complexity in the glass kettle body molding process, resulting in a decrease in product yield. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, this utility model provides a kettle and an electric kettle.

[0005] This utility model is achieved through the following technical solution:

[0006] Kettle, including:

[0007] A glass pitcher body having an inner cavity for holding liquid;

[0008] A heat-insulating outer shell, the heat-insulating outer shell being disposed at least around the outer side wall of the glass vessel; and

[0009] A connecting component, at least a portion of which is located between the outer wall of the glass pot body and the inner wall of the heat insulation shell, the connecting component connecting the outer wall of the glass pot body and the inner wall of the heat insulation shell to connect the heat insulation shell to the glass pot body, wherein the connecting component is separately disposed from the glass pot body.

[0010] The kettle of this utility model connects the heat-insulating outer shell to the glass kettle body through a connecting component. The connecting component and the glass kettle body are separate, meaning that the connecting component and the glass kettle body are independently constructed structures. Therefore, this structural design eliminates the need for an integrally formed annular protrusion structure on the outer wall of the glass kettle body, simplifies the glass kettle body forming process, and thus improves the yield rate of the glass kettle body. The improved yield rate of the glass kettle body helps to reduce the overall cost of the kettle and is more conducive to the widespread application of the kettle.

[0011] In one embodiment, an adhesive layer is provided between the connecting component and the outer wall of the glass pot body. The adhesive layer connects the connecting component and the outer wall of the glass pot body to reliably connect the connecting component and the glass pot body, thereby improving the connection stability between the heat insulation shell and the glass pot body.

[0012] In one embodiment, the inner wall of the connecting component has a limiting groove, which surrounds the outer wall of the glass vessel and accommodates the adhesive layer. The limiting groove is used to prevent the adhesive layer from detaching from the connecting component. The limiting groove can limit the adhesive layer, which helps to improve the connection stability between the connecting component and the glass vessel. Furthermore, by surrounding the outer wall of the glass vessel, the limiting groove ensures that the adhesive layer is evenly distributed, avoiding displacement or uneven thickness, thus improving bonding reliability. Secondly, the physical structure of the limiting groove restricts the flow or overflow of the adhesive layer, especially in environments with high temperature and vibration, effectively preventing the adhesive layer from detaching and enhancing long-term stability. Additionally, the adhesive layer being enclosed by the limiting groove creates a mechanical interlocking effect, sharing some of the stress (such as thermal expansion and contraction or external impact), reducing the risk of interface cracking.

[0013] In one embodiment, the connecting component includes:

[0014] A clamp, which is fitted onto the outer wall of the glass vessel, surrounds the vertical center line of the glass vessel, and has openable and closable ends to adjust its inner diameter. Both ends of the clamp have connecting portions.

[0015] Fasteners are provided to connect the connecting portions located at both circumferential ends of the clamp, thereby connecting the two circumferential ends of the clamp together. The clamp's adjustable inner diameter allows it to accommodate glass containers of different diameters, reducing manufacturing tolerance requirements and improving compatibility. Secondly, the clamp's openable ends facilitate quick installation or disassembly without the need for adhesives or welding, simplifying assembly and maintenance processes. Furthermore, the fasteners ensure a tight fit between the clamp and the glass container, preventing loosening and enhancing structural stability, thus ensuring a reliable connection between the connecting components and the glass container.

[0016] In one embodiment, one of the connecting portions located at both circumferential ends of the hoop has a first connecting hole and the other has a second connecting hole.

[0017] The head of the fastener abuts against the connecting portion having the first through-hole, and the shank of the fastener passes through the first through-hole and is screwed to the second connecting hole.

[0018] Alternatively, the head of the fastener abuts against the connecting portion having the first connecting hole, and the shank of the fastener passes through the first connecting hole and the second connecting hole in sequence, with a nut screwed onto the shank of the fastener, the nut abutting against the connecting portion having the second connecting hole. Here, the fastener's engagement with the first and second connecting holes enables rapid alignment and locking, reducing assembly steps and improving assembly efficiency. Secondly, the threaded connection provides a mechanical self-locking function, which is more reliable than simple snap-fit ​​or friction fixing, effectively resisting loosening caused by vibration or external force. Furthermore, the inner diameter of the clamp can be finely adjusted by rotating the fastener to ensure a tight fit with the glass container, adapting to different sizes or changes in thermal expansion and contraction.

[0019] In one embodiment, the inner wall of the heat insulation shell and the outer wall of the connecting component are interference-fitted. The interference fit achieves self-locking through physical interference, ensuring a tight fit between the heat insulation shell and the connecting component, thereby improving the connection stability between the heat insulation shell and the connecting component, eliminating the need for auxiliary fixing methods such as bolts and adhesives, simplifying the structure, and reducing costs. Secondly, the frictional force of the interference fit can resist vibration or external impact, preventing components from loosening or shifting, and improving overall reliability. In addition, the interference fit supports non-destructive disassembly, facilitating cleaning or replacement of the heat insulation shell.

[0020] In one embodiment, the inner wall of the thermal insulation shell has multiple protrusions arranged sequentially around the vertical centerline of the thermal insulation shell, and each protrusion is interference-fitted with the outer wall of the connecting component. The multiple protrusions forming multi-point interference with the connecting component facilitates assembly and results in a more uniform stress distribution compared to a single interference fit, reducing the risk of deformation. Secondly, the multiple protrusions significantly improve vibration and torsional resistance by dispersing friction and creating mechanical interlocking effects, thereby further enhancing the connection stability between the thermal insulation shell and the connecting component. Furthermore, the protrusions reduce the contact area, shorten the heat conduction path, and retain the air insulation layer, improving overall thermal insulation performance. Finally, replacing the single interference structure with multiple protrusions reduces material usage, achieving a lightweight design.

[0021] In one embodiment, the outer wall of the connecting component has a limiting portion that abuts against the heat-insulating shell to restrict the upward movement of the heat-insulating shell relative to the glass pot body. The mechanical abutment between the limiting portion and the heat-insulating shell effectively prevents the heat-insulating shell from shifting upwards, ensuring that the heat-insulating shell and the glass pot body maintain their designed relative positions. Furthermore, the physical restraint of the heat-insulating shell by the limiting portion is more resistant to high-temperature aging than adhesive fixation, effectively preventing displacement problems caused by material creep after long-term use.

[0022] In one embodiment, the heat-insulating outer shell includes:

[0023] The outer shell body is sleeved on the outer side wall of the lower part of the connecting component, and the outer shell body is arranged around the outer side wall of the glass pot body;

[0024] A connecting sleeve, located above the outer shell body, with its lower end abutting against the upper end of the outer shell body, the connecting sleeve being fitted onto the outer side wall of the upper part of the connecting component, and the connecting sleeve surrounding the outer side wall of the glass container; and

[0025] The handle has its lower end connected to the outer shell body and its upper end connected to the connecting sleeve. The heat-insulating shell, composed of the outer shell body, connecting sleeve, and handle, forms a segmented structure. This segmented structure allows for the assembly of the outer shell body first, then the connecting sleeve, and finally the handle, reducing assembly difficulty and improving efficiency. Secondly, the handle acts as a structural beam, bidirectionally connecting the outer shell body and the connecting sleeve, forming a spatial triangular support system that distributes stress, thus reducing the risk of mechanical stress concentration in the glass vessel. Furthermore, the segmented structure reduces the difficulty of single-piece injection molding, thus lowering costs.

[0026] Electric kettles, including the kettles mentioned above.

[0027] The electric kettle of this utility model, by adopting the aforementioned kettle, also uses a connecting component to connect the heat-insulating outer shell and the glass kettle body. The connecting component and the glass kettle body are separately set, that is, the connecting component and the glass kettle body are both independently set structures. Therefore, this structural design can eliminate the need for an integrally formed annular protrusion structure on the outer wall of the glass kettle body. Thus, it can simplify the glass kettle body forming process, thereby improving the yield rate of the glass kettle body. The improvement of the yield rate of the glass kettle body helps to reduce the overall cost of the kettle and is more conducive to the promotion and application of the kettle.

[0028] The beneficial effects of this utility model are:

[0029] The kettle of this utility model connects the heat-insulating outer shell to the glass kettle body through a connecting component. The connecting component and the glass kettle body are separate, meaning that the connecting component and the glass kettle body are independently constructed structures. Therefore, this structural design eliminates the need for an integrally formed annular protrusion structure on the outer wall of the glass kettle body, simplifies the glass kettle body forming process, and thus improves the yield rate of the glass kettle body. The improved yield rate of the glass kettle body helps to reduce the overall cost of the kettle and is more conducive to the widespread application of the kettle. Attached Figure Description

[0035] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and therefore may vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0036] Please see Figures 1-3 This invention illustrates a preferred embodiment of a kettle, comprising:

[0037] The glass vessel 1 has an inner cavity 11 for holding liquid.

[0038] The heat-insulating outer shell 2 is disposed at least around the outer side wall of the glass pot body 1; and

[0039] The connecting component 3 is located at least partly between the outer wall of the glass pot body 1 and the inner wall of the heat insulation shell 2. The connecting component 3 connects the outer wall of the glass pot body 1 and the inner wall of the heat insulation shell 2 to connect the heat insulation shell 2 to the glass pot body 1. The connecting component 3 is separate from the glass pot body 1.

[0040] The kettle of this utility model connects the heat-insulating shell 2 and the glass kettle body 1 together through the connecting component 3. The connecting component 3 and the glass kettle body 1 are separate, that is, the connecting component 3 and the glass kettle body 1 are independently set structures. Therefore, this structural design can eliminate the need for an integrally formed annular protrusion structure on the outer wall of the glass kettle body 1, which can simplify the molding process of the glass kettle body 1 and thus improve the yield rate of the glass kettle body 1. The improvement of the yield rate of the glass kettle body 1 helps to reduce the overall cost of the kettle and is more conducive to the promotion and application of the kettle.

[0041] In one embodiment, the connecting component 3 is arranged around the vertical center line of the glass pot body 1, that is, the connecting component 3 is a ring structure, so as to increase the contact area between the connecting component 3 and the glass pot body 1, thereby improving the connection stability between the heat insulation shell 2 and the glass pot body 1.

[0042] See Figure 2 In one embodiment, an adhesive layer 4 is provided between the connecting component 3 and the outer wall of the glass pot body 1. The adhesive layer 4 connects the connecting component 3 and the outer wall of the glass pot body 1 to reliably connect the connecting component 3 and the glass pot body 1 together, thereby improving the connection stability between the heat insulation shell 2 and the glass pot body 1.

[0043] In one embodiment, when the connecting component 3 is arranged around the vertical center line of the glass pot body 1, the adhesive layer 4 is also arranged around the vertical center line of the glass pot body 1 to increase the contact area between the adhesive layer 4 and the glass pot body 1, thereby further improving the connection stability between the connecting component 3 and the glass pot body 1, that is, further improving the connection stability between the heat insulation shell 2 and the glass pot body 1.

[0044] In one embodiment, the adhesive layer 4 may be formed by curing an adhesive to ensure that the connecting component 3 and the glass pot body 1 are firmly bonded together, thereby further improving the connection stability between the connecting component 3 and the glass pot body 1.

[0045] See Figures 2-3In one embodiment, the inner wall of the connecting component 3 has a limiting groove 311, which surrounds the outer wall of the glass pot body 1. The limiting groove 311 accommodates the adhesive layer 4 and is used to prevent the adhesive layer 4 from detaching from the connecting component 3. The limiting groove 311 can limit the adhesive layer 4, which helps to improve the connection stability between the connecting component 3 and the glass pot body 1. In particular, by surrounding the outer wall of the glass pot body 1, the limiting groove 311 ensures that the adhesive layer 4 is evenly distributed, avoiding displacement or uneven thickness, and improving the bonding reliability. Secondly, the physical structure of the limiting groove 311 restricts the flow or overflow of the adhesive layer 4, which can effectively prevent the adhesive layer 4 from detaching, especially in environments with high temperature and vibration, and enhance long-term stability. In addition, the adhesive layer 4 is wrapped by the limiting groove 311, forming a mechanical interlocking effect, sharing some of the stress (such as thermal expansion and contraction or external impact), and reducing the risk of interface cracking.

[0046] See Figures 1-3 In one embodiment, the connecting component 3 includes:

[0047] A clamp 31 is fitted onto the outer wall of the glass vessel body 1, and the clamp 31 is arranged around the vertical center line of the glass vessel body 1. The two ends of the clamp 31 are openable and closable to adjust the inner diameter of the clamp 31. Each end of the clamp 31 has a connecting portion 312.

[0048] Fastener 32 connects to connecting portions 312 located at both circumferential ends of the clamp 31, thereby connecting the two circumferential ends of the clamp 31 together. The clamp 31 has an adjustable inner diameter, accommodating glass pot bodies 1 of different diameters, reducing manufacturing tolerance requirements and improving compatibility. Secondly, the clamp 31's openable ends facilitate quick installation or disassembly without the need for adhesives or welding, simplifying assembly and maintenance processes. Furthermore, fastener 32 ensures that the clamp 31 fits tightly against the glass pot body 1, preventing loosening and enhancing structural stability, thus reliably connecting the connecting component 3 to the glass pot body 1.

[0049] In one embodiment, one of the connecting portions 312 located at both circumferential ends of the band 31 has a first connecting hole 3121 and the other has a second connecting hole (not shown in the figure).

[0050] The head of the fastener 32 abuts against the connecting portion 312 with the first connecting hole 3121. The shank of the fastener 32 passes through the first connecting hole 3121 and is screwed into the second connecting hole, meaning the fastener 32 is specifically a screw. The fastener 32, through the engagement of the first connecting hole 3121 and the second connecting hole, achieves quick alignment and locking, reducing assembly steps and improving assembly efficiency. Secondly, the threaded connection provides a mechanical self-locking function, which is more reliable than simple snap-fit ​​or friction fixing and can effectively resist loosening caused by vibration or external force. Furthermore, by rotating the fastener 32, the inner diameter of the band 31 can be finely adjusted to ensure a tight fit with the glass container 1, adapting to different sizes or changes in thermal expansion and contraction.

[0051] Of course, in other embodiments, the head of the fastener 32 abuts against one of the connecting parts 312, the rod of the fastener 32 passes through the first connecting hole and the second connecting hole, and the rod of the fastener 32 is screwed with a nut, which abuts against another connecting part 312 away from the head of the fastener 32. That is, the fastener 32 is a bolt. This structure can also reliably connect the two connecting parts 312 together.

[0052] Of course, in other embodiments, the fastener 32 described above may also be a rivet.

[0053] In one embodiment, the connecting component 3 can be a closed connecting ring, which is sleeved on the outer wall of the glass pot body 1. The central hole of the connecting ring is adapted to the outer wall of the glass pot body 1. This structure can also connect the connecting component 3 to the glass pot body 1, but it has higher requirements for the external dimensions of the glass pot body 1 and poorer compatibility.

[0054] In one embodiment, the connecting component 3 may be made of plastic or metal.

[0055] In one embodiment, the inner wall of the heat insulation shell 2 and the outer wall of the connecting component 3 are interference-fitted. The interference fit achieves self-locking through physical interference, ensuring that the heat insulation shell 2 and the connecting component 3 fit tightly together, thereby improving the connection stability between the heat insulation shell 2 and the connecting component 3, eliminating the need for auxiliary fixing methods such as bolts and adhesives, simplifying the structure and reducing costs. Secondly, the friction of the interference fit can resist vibration or external impact, preventing the components from loosening or shifting, and improving overall reliability. In addition, the interference fit can support non-destructive disassembly, making it easy to clean or replace the heat insulation shell 2.

[0056] In one embodiment, the inner wall of the heat insulation shell 2 has multiple protrusions 211, which are arranged sequentially around the vertical centerline of the heat insulation shell 2. Each protrusion 211 is interference-fitted with the outer wall of the connecting component 3. The multiple protrusions 211 form multi-point interference with the connecting component 3, which is easier to assemble and results in a more uniform stress distribution than a single interference fit, reducing the risk of deformation. Secondly, the multiple protrusions significantly improve vibration and torsional resistance by dispersing friction and through mechanical interlocking effects, thereby further improving the connection stability between the heat insulation shell 2 and the connecting component 3. Furthermore, the protrusions 211 reduce the contact area, lower the heat conduction path, and retain the air insulation layer, improving overall heat insulation performance. Additionally, replacing the single interference structure with multiple protrusions 211 reduces material usage, achieving a lightweight design.

[0057] Of course, in other embodiments, a connection structure can be provided between the heat insulation shell 2 and the connecting component 3 to connect the heat insulation shell 2 and the connecting component 3 together. The connection structure can be a connecting block, a snap-fit ​​structure, or any kind of fastener such as screws, bolts, or rivets.

[0058] In one embodiment, the outer wall of the connecting component 3 has a limiting portion 313, which abuts against the heat insulation shell 2 to restrict the upward movement of the heat insulation shell 2 relative to the glass pot body 1. The mechanical abutment between the limiting portion 313 and the heat insulation shell 2 effectively prevents the heat insulation shell 2 from shifting upwards, ensuring that the heat insulation shell 2 and the glass pot body 1 always maintain their designed relative positions. Furthermore, the physical restraint of the heat insulation shell 2 by the limiting portion 313 is more resistant to high-temperature aging than adhesive fixation, effectively avoiding displacement problems caused by material creep after long-term use.

[0059] In one embodiment, the heat-insulating outer shell 2 includes:

[0060] The outer shell body 21 is fitted onto the outer side wall of the lower part of the connecting component 3, and the outer shell body 21 is arranged around the outer side wall of the glass pot body 1;

[0061] Connecting sleeve 22, located above the outer shell body 21, with its lower end abutting against the upper end of the outer shell body 21, and fitted onto the outer side wall of the upper part of the connecting component 3; connecting sleeve 22 surrounds the outer side wall of the glass pot body 1; and

[0062] The handle 23 has its lower end connected to the outer shell body 21 and its upper end connected to the connecting sleeve 22. The heat-insulating shell 2, composed of the outer shell body 21, connecting sleeve 22, and handle 23, forms a segmented structure. This segmented structure allows for the assembly of the outer shell body 21 first, then the connecting sleeve 22, and finally the handle 23, reducing assembly difficulty and improving efficiency. Secondly, the handle 23 acts as a structural beam, bidirectionally connecting the outer shell body 21 and the connecting sleeve 22, forming a spatial triangular support system that disperses stress, thus reducing the risk of mechanical stress concentration in the glass vessel 1. Furthermore, the segmented structure reduces the difficulty of single-unit injection molding, thus lowering costs.

[0063] It is understood that the upper end of the handle 23 can be connected to the outer shell 21 by fasteners, and the lower end of the handle 23 can also be connected to the connecting sleeve 22 by fasteners. The fasteners can be any one of screws, bolts, rivets, etc.

[0064] Of course, in other embodiments, the heat insulation shell 2 can also be a one-piece structure, that is, the heat insulation shell 2 is a one-piece molded part, which can simplify the structure and make assembly easier.

[0065] In one embodiment, the heat insulation shell 2 has a central hole, which extends through the heat insulation shell 2 from both the top and bottom.

[0066] The kettle also includes:

[0067] The bottom cover (not shown in the figure) is connected to the lower end of the heat insulation shell 2 and covers the lower opening of the central hole to seal the lower end of the heat insulation shell 2.

[0068] A preferred embodiment of this utility model provides an electric kettle, including the kettle described above.

[0069] The electric kettle of this utility model, by adopting the aforementioned kettle, also connects the heat-insulating outer shell 2 and the glass kettle body 1 together through the connecting component 3. The connecting component 3 and the glass kettle body 1 are separately set, that is, the connecting component 3 and the glass kettle body 1 are both independently set structures. Therefore, this structural design can eliminate the need for an integrally formed annular protrusion structure on the outer wall of the glass kettle body 1, which can simplify the molding process of the glass kettle body 1, thereby improving the yield rate of the glass kettle body 1. The improvement of the yield rate of the glass kettle body 1 helps to reduce the overall cost of the kettle and is more conducive to the promotion and application of the kettle.

[0070] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
