Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of water boiling containers, specifically providing a kettle and its lid. Background Technology
[0002] In daily life, kettles are commonly used appliances for heating water. A kettle typically consists of a body and a lid. When boiling water, especially when the water is boiling vigorously, noise is transmitted through the kettle body and lid, affecting people's work, study, or rest, resulting in a poor user experience.
[0003] Because of the water, the kettle body absorbs some vibrations, resulting in relatively less noise transmitted to the outside. The noise from boiling water mainly comes from the formation and bursting of bubbles, which are transmitted to the lid via the air and then to the outside. Meanwhile, existing kettle lids have poor heat retention, causing the water inside to cool down quickly after boiling, making it impossible to keep hot water warm for an extended period. Utility Model Content
[0004] One objective of this invention is to solve the problem of poor heat preservation and noise reduction performance of existing kettle lids.
[0005] To achieve the above objectives, the present invention provides a kettle lid in a first aspect, comprising:
[0006] Outer cover;
[0007] A base cover is disposed on the inner side of the outer cover, and the side of the base cover facing the outer cover is provided with multiple grooves;
[0008] A heat-insulating component is disposed between the base cover and the outer cover. The heat-insulating component abuts against the base cover to shield the groove, thereby reducing the noise transmitted from inside the kettle to the outside through the kettle cover at the groove due to the change in the transmission medium.
[0009] Optionally, the plurality of grooves are distributed in multiple rings along the radial direction of the base cover.
[0010] Optionally, each ring contains a plurality of grooves.
[0011] Optionally, a partition rib is provided between adjacent grooves, and the partition rib abuts against the insulation member to support the insulation member.
[0012] Optionally, the outer cover is provided with an abutment structure extending toward the insulation member, so that the outer cover presses the insulation member against the base cover through the abutment structure, thereby defining a flat cavity between the outer cover and the insulation member to reduce the noise emitted by the kettle through the cavity.
[0013] Optionally, the outer cover engages with the base cover.
[0014] Optionally, the kettle lid further includes an inner lid disposed on the side of the base lid away from the outer lid; the inner lid is spaced from the base lid and thus defines a gap to reduce noise transmitted from the kettle through the gap.
[0015] Optionally, the inner cover is provided with an annular flange extending toward the outer cover, and the base cover is provided with an annular protrusion extending away from the outer cover. The annular protrusion is located outside the annular flange and spaced apart from the annular flange. The lid also includes a sealing ring, which is embedded between the annular protrusion and the annular flange and is fixed by at least one of the annular protrusion and the annular flange.
[0016] Optionally, the sealing ring is provided with an abutment ring extending radially outward therefrom, the abutment ring being used to abut against the inner wall of the kettle body.
[0017] The present invention provides a kettle in a second aspect, comprising a kettle body and a kettle lid as described in any one of the first aspects.
[0018] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, the heat insulation effect of the kettle lid is improved by setting a heat-insulating component between the outer lid and the base lid. By setting multiple grooves on the side of the base lid facing the outer lid and making the heat-insulating component abut against the base lid to cover the grooves, the noise transmitted from inside the kettle through the lid is reduced at the grooves due to the change in the transmission medium. Therefore, the kettle lid of this utility model has good heat insulation and noise reduction performance.
[0019] Furthermore, by setting partition ribs between adjacent grooves to support the insulation component, the deformation of the insulation component due to thermal expansion and contraction during long-term use is effectively prevented, and it from abutting against the bottom wall of the groove, thus affecting the noise reduction effect of the lid.
[0020] Furthermore, by defining a flat cavity between the outer lid and the insulation component, the noise transmitted from the kettle is reduced, further improving the noise reduction effect of the kettle lid.
[0021] Furthermore, by spacing the inner lid from the base lid and thus defining a gap, the noise emitted by the kettle is reduced, further enhancing the noise reduction effect of the lid.
[0022] Furthermore, by having the lid abut against the inner wall of the kettle body using the sealing ring's abutment ring, heat loss through the gap between the lid and the kettle body is prevented, thus improving the kettle's heat retention effect.

[0037] like Figure 1 As shown, in some embodiments of this utility model, the kettle 001 includes a kettle body 100 and a kettle lid 200. The kettle lid 200 is used to open and close the kettle body 100.
[0038] from Figure 1 As can be seen, a handle can also be fixed on the body of the kettle 100 for easy gripping by the user.
[0039] Furthermore, the lid 200 can be rotatably connected to the handle so that the lid 200 can be opened and closed by rotating the body 100.
[0040] The following reference Figures 2 to 5 The lid 200 of this utility model will be described in detail below.
[0041] like Figures 2 to 5 As shown, in some embodiments of this utility model, the lid 200 includes an outer lid 210, a base lid 220, and a heat-insulating component 230.
[0042] The base cover 220 is disposed inside the outer cover 210 and is fixedly connected to the outer cover 210. The side of the base cover 220 facing the outer cover 210 is provided with multiple grooves 221.
[0043] In some embodiments of this utility model, the outer cover 210 and the base cover 220 are snapped together. For example, the outer cover 210 is provided with a slot, and the base cover 220 is provided with a buckle. By snapping the buckle into the slot, the outer cover 210 and the base cover 220 are snapped together.
[0044] Furthermore, in other embodiments of this invention, those skilled in the art can also connect the outer cover 210 and the base cover 220 together in any other feasible manner as needed. For example, they can fix them together by means of screws.
[0045] like Figure 5 As shown, in some embodiments of this utility model, the heat insulation component 230 is disposed between the base cover 220 and the outer cover 210. The heat insulation component 230 abuts against the base cover 220 to cover the groove 221, thereby reducing the noise transmitted from inside the kettle 001 through the kettle cover 200 at the groove 221 due to the change in the transmission medium.
[0046] The insulation component 230 is generally a ring-shaped plate structure. Of course, those skilled in the art can also set the insulation component 230 into other feasible structures as needed, such as polygons, ellipses, etc.
[0047] Furthermore, the insulation component 230 can be made of any feasible material such as aerogel, rock wool, or ceramic fiber.
[0048] Those skilled in the art will understand that by providing a heat-insulating member 230 between the outer cover 210 and the base cover 220, the heat insulation effect of the kettle lid 200 is improved. By providing multiple grooves 221 on the side of the base cover 220 facing the outer cover 210, and by having the heat-insulating member 230 abut against the base cover 220 to cover the grooves 221, the noise transmitted from inside the kettle 001 through the kettle lid 200 is reduced at the grooves 221 due to the change in the transmission medium. Therefore, the kettle lid 200 of this invention has good heat insulation and noise reduction performance.
[0049] like Figure 2 As shown, in some embodiments of this utility model, multiple grooves 221 are distributed in multiple rings along the radial direction of the base cover 220. Furthermore, no grooves 221 are provided in the central region of the base cover 220 to ensure the structural strength of the base cover 220.
[0050] from Figure 2 As can be seen, there are multiple grooves 221 in each ring, so that there is more space between the insulation component 230 and the base cover 220, so as to better reduce the transmission of noise.
[0051] Continue reading Figure 2In some embodiments of this utility model, a partition rib 222 is provided between adjacent grooves 221, and the partition rib 222 abuts against the heat insulation component 230 to support the heat insulation component 230.
[0052] Those skilled in the art will understand that by providing a partition rib 222 between adjacent grooves 221 to support the insulation component 230, the insulation component 230 is effectively prevented from deforming due to thermal expansion and contraction during long-term use and from abutting against the bottom wall of the groove 221, thus affecting the noise reduction effect of the lid 200.
[0053] like Figure 3 and Figure 5 As shown, in some embodiments of this utility model, the outer cover 210 is provided with an abutment structure 211 extending toward the insulation member 230, so that the outer cover 210 presses the insulation member 230 onto the base cover 220 through the abutment structure 211, thereby defining a flat cavity 201 between the outer cover 210 and the insulation member 230 (e.g., Figure 5 (As shown), so as to reduce the noise transmitted from the kettle 001 through the cavity 201.
[0054] Those skilled in the art will understand that by defining a flat cavity 201 between the outer cover 210 and the insulation member 230, the noise transmitted from the kettle 001 is reduced, further improving the noise reduction effect of the kettle cover 200.
[0055] like Figures 2 to 5 As shown, in some embodiments of this invention, the lid 200 further includes an inner lid 240, which is disposed on the side of the base lid 220 away from the outer lid 210. Furthermore, the inner lid 240 is spaced from the base lid 220 and thus defines a gap 202 (e.g., ...). Figure 5 (As shown), to reduce the noise emitted by the kettle 001 through the gap 202.
[0056] Those skilled in the art will understand that by spacing the inner lid 240 from the base lid 220 and thus defining the gap 202, the noise emitted by the kettle 001 is reduced, further enhancing the noise reduction effect of the lid 200.
[0057] Furthermore, the width of the gap 202 can be selected from any value between 0.5mm and 5mm. The width of the gap 202 can be the same or different throughout. For example, the width of the gap 202 can be the same at all points and can be 1mm.
[0058] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments of this utility model, the inner cover 240 is provided with an annular flange 241 extending toward the outer cover 210, and the base cover 220 is provided with an annular protrusion 223 extending away from the outer cover 210. The annular protrusion 223 is located outside the annular flange 241 and is spaced apart from the annular flange 241.
[0059] Continue reading Figure 2 , Figure 3 and Figure 5 In some embodiments of this utility model, the lid 200 further includes a sealing ring 250, which is embedded between the annular protrusion 223 and the annular flange 241 and is fixed by at least one of the annular protrusion 223 and the annular flange 241.
[0060] Specifically, the portion of the sealing ring 250 embedded between the annular protrusion 223 and the annular flange 241 can be interference-fitted with the annular protrusion 223, interference-fitted with the annular flange 241, or clamped together by the annular protrusion 223 and the annular flange 241.
[0061] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this utility model, the sealing ring 250 is provided with an abutment ring 251 extending radially outward therefrom, the abutment ring 251 being used to abut against the inner wall of the kettle body 100 of the kettle 001.
[0062] Those skilled in the art will understand that by having the lid 200 abut against the inner wall of the body 100 via the abutment ring 251 of the sealing ring 250, heat loss from the gap between the lid 200 and the body 100 is prevented, thereby improving the heat preservation effect of the kettle 001.
[0063] In some embodiments of this invention, the sealing ring 250 may be made of silicone or rubber.
[0064] Based on the foregoing description, those skilled in the art will understand that the lid 200 of this utility model not only improves the heat preservation effect of the kettle 001, but also reduces noise and enhances the user experience.
[0065] In addition, in other embodiments of this utility model, those skilled in the art may fill the space between the outer cover 210 and the base cover 220 with sound-absorbing material, sound-insulating foam, or sound-insulating membrane as needed to further improve the noise reduction effect of the lid 200.
[0066] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.
