Description

Technical Field

[0001] This utility model relates to the field of small household appliances, and more specifically, to a heating cup. Background Technology

[0002] As living standards improve, people are paying more attention to health and thus placing higher demands on their lives, such as the essential and frequent act of drinking water. For personal reasons, to protect their stomachs and reduce irritation, more and more people are habitually drinking warm water. Indoors, whether at home or at work, hot water sources are usually plentiful. However, when out and about, especially during outings or outdoor trips, traditional water bottles lack heating and insulation, making hot water a luxury. Even with an insulated bottle, it's often insufficient to meet the need for prolonged drinking and comes with considerable weight. The emergence of electric water bottles has solved this problem. In many external environments, users not only have a container for readily available hot water but also enjoy a dedicated, hygienic, and fast-heating experience. However, existing electric water bottles are already quite functional. As the number of similar products on the market increases, competition intensifies. Therefore, the surface appearance has become a crucial factor. For all-metal sidewall constructions, simply changing the shape and pattern of the surface is unlikely to be effective; instead, altering the structural design to create a sleek, one-piece metal surface better meets consumer needs.

[0003] Electric kettles typically have a vacuum layer between the outer shell and the inner liner. This vacuum prevents heat transfer and convection. Traditionally, electric kettles are assembled by welding the outer shell and inner liner together, then creating a vacuum layer in the space between them. The outer shell is then subjected to electrolysis, polishing / grinding, and oiling. However, after oiling, the welded area between the inner liner and the outer shell often displays a different color than other areas, significantly affecting the aesthetics. Current technology has achieved a higher yield by avoiding the vacuum layer during welding, but it's difficult to guarantee that the outermost metal layer won't participate in the welding process. If the outermost metal does participate, even on the inner surface, it can cause dents on the outer surface, ruining the seamless appearance. Utility Model Content

[0004] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide a heating cup to solve the problem that welding causes the integral metallic feel of the outermost surface to be destroyed, and to make the heating cup more aesthetically pleasing.

[0005] The technical solution adopted by this utility model is to provide a heating cup, including: a hollow cup body and a cup lid assembly installed on the upper part of the cup body. The cup body includes: an inner wall forming a liquid cavity; a vacuum wall disposed outside the inner wall and connected to the inner wall to form a vacuum insulation layer; and an outer wall sleeved outside the vacuum wall and covering the vacuum wall; the outer wall extends to the lower part of the liquid cavity and forms a mounting cavity; a heating component and a control component are disposed in the mounting cavity; the heating component is connected to the liquid cavity; the control component is connected to the heating component and communicates with the outside through the outer wall; the vacuum insulation layer acts on the side wall of the liquid cavity.

[0006] The liquid cavity is used to hold liquid. The vacuum insulation layer formed by the connection between the vacuum wall and the inner wall keeps the liquid in the liquid cavity warm. The vacuum wall and the inner wall are usually connected by welding. The outer wall can cover the welding marks left by polishing and oiling after welding on the vacuum wall, making the overall appearance more beautiful, optimizing the user experience, and improving the sales prospects of manufacturers.

[0007] Compared to the inner wall and vacuum wall extending to form the mounting cavity, the outer wall extending to form the mounting cavity provides a larger space for accommodating functional components.

[0008] The heating element is used to heat the liquid in the liquid cavity, and the control element is used to control the operation of the heating element, etc. The control element is connected to the outside for convenient user operation.

[0009] Furthermore, the inner wall includes:

[0010] A main body segment forms a liquid cavity, with an inlet at the top connecting the liquid cavity to the outside; the upper end of the main body segment extends upward to form an interface segment away from the vacuum insulation layer; the upper end of the vacuum wall is connected to the lower part of the interface segment; the upper end of the outer wall is connected to the upper part of the interface segment; a gap is left between the upper end of the vacuum wall and the upper end of the outer wall.

[0011] The main body section is the part that directly contacts the liquid, which enters and exits the liquid cavity through the inlet. The upper end of the vacuum wall is connected to the lower part of the interface section; the upper end of the outer wall is connected to the upper part of the interface section; and there is a gap between the upper end of the vacuum wall and the upper end of the outer wall. This allows the part where the outer wall connects to the interface section to avoid the vacuum insulation layer formed by the inner wall and the vacuum wall, ensuring that the connection of the outer wall will not damage the vacuum layer. For users, this ensures that the insulation performance of the heating cup is not affected; for manufacturers, since the outer wall avoids the vacuum layer during production, the connection difficulty is reduced, and production efficiency is improved; furthermore, it avoids rework and material waste caused by vacuum leakage due to the connection of the outer wall, saving production costs.

[0012] Furthermore, the lower part of the inner wall is provided with an annular lower extension piece; the upper part of the annular lower extension piece is connected to the liquid cavity; the lower end of the vacuum wall extends to the bottom of the liquid cavity and is connected to the lower part of the annular lower extension piece; the annular lower extension piece is provided with an extraction structure for evacuating the vacuum insulation layer.

[0013] If the lower end of the vacuum wall is directly connected to the main body of the inner wall, welding marks can easily be left inside the liquid cavity, affecting the user's aesthetic experience. Therefore, connecting the vacuum wall to the inner wall via a lower extension plate maintains the appearance of the liquid cavity, and during production, workers do not need to consider the impact on the liquid cavity, thus improving production efficiency.

[0014] Similarly, the vacuum extraction structure is located on the lower extension plate, which helps maintain the aesthetic appearance of the liquid cavity. Furthermore, performing vacuum extraction on the lower extension plate is more convenient than performing it within the liquid cavity, further improving production efficiency.

[0015] Furthermore, the cup lid assembly includes: an inner lid connected to the inner wall; an outer lid fitted over the inner lid; the outer lid forming an open container.

[0016] The inner cover matches the inlet and covers the inlet of the liquid cavity. The outer cover forms an open container that allows users to easily hold the liquid poured from the heated cup. It can be put on the inner cover for easy carrying and optimizes the user experience.

[0017] Furthermore, the inner cover includes: an inner liner, a snap-fit ​​component, and a top cover component; the snap-fit ​​component is sleeved on the outer side of the inner liner and connected to the inner wall; the top cover component is connected to the top of the snap-fit ​​component; the snap-fit ​​component is also provided with a sealing element, which is used to abut against the edge of the inlet.

[0018] The inner liner forms a cavity communicating with the liquid chamber. The snap-fit ​​component is snapped into the inner wall, and the top cover is attached to the top of the snap-fit ​​component for easy removal and placement of the entire inner cover. The sealing component abuts against the edge of the inlet to prevent water vapor from flowing out from the gap between the snap-fit ​​component and the edge of the inlet, thereby improving the heat preservation effect.

[0019] Furthermore, the inner liner, the snap-fit ​​component, and the top cover component are provided with a plurality of interconnected vent holes; the vent holes form a ventilated channel that communicates with the outside of the inner cover; and the ventilated channel is provided with a waterproof and ventilated component.

[0020] Water vapor inside the heating cup flows to the outside through the venting channel. The waterproof and venting component is a structure that allows water vapor to pass through while blocking water droplets. This component can be located between the inner liner and the snap-fit ​​part, or between the snap-fit ​​part and the top cover. By placing it in the venting channel, it blocks the liquid, allowing water vapor to escape while keeping the water sealed inside the heating container. This eliminates the need to open the lid, greatly simplifying the heating process and preventing both hot water leakage and the danger of steam buildup.

[0021] Furthermore, the surface of the outer wall is provided with an annular flexible closure; the flexible closure includes: a protruding ring that abuts against the inner sidewall of the outer cover; and a protruding edge that extends to the lower part of the outer cover and engages with the lower edge of the outer cover.

[0022] The outer cover is secured to the heating cup via the protruding ring. Its flexible closure is made of a flexible material, facilitating easy removal and placement. A gap exists between the lower edge of the outer cover and the outer wall, with the protruding edge positioned within this gap. This reduces water vapor leakage when the liquid in the heating cup is being kept warm, improving insulation. Simultaneously, the protruding edge prevents the outer cover from rubbing against the outer wall and causing wear, thus maintaining the heating cup's aesthetic appeal.

[0023] Furthermore, the flexible closure is provided with an air guide channel; the air guide channel forms an avoidance notch on the convex edge and an avoidance break on the convex ring; the air guide channel is used to connect the interior and exterior of the outer cover.

[0024] When the heating cup boils water, the steam flows through the vent channel to the clearance opening, then to the clearance recess, and finally out to the outside. This allows steam to escape through the vent channel, eliminating the need to open the outer lid while boiling water, making it convenient for users. Furthermore, the vent channel design is simple and easy to manufacture.

[0025] Furthermore, the vacuum wall is provided with a positioning protrusion that abuts against the outer wall.

[0026] During production, the upper end of the outer wall is first connected to the interface section of the inner wall, while the lower end remains movable. A positioning protrusion on the outer wall abuts against it, preventing tilting or shifting. This greatly facilitates the connection of the lower end of the outer wall, improves production efficiency, and prevents increased defect rates due to tilting at the lower end, saving materials and reducing production costs. Furthermore, the protrusion makes the structure between the vacuum wall and the outer wall more compact, robust, and durable. Preferably, the positioning protrusion is located at the lower part of the vacuum wall.

[0027] Furthermore, the outer wall is provided with a mounting post and a handle welded to the outer wall; the handle is connected to the outer wall via the mounting post, and / or,

[0028] The portion of the outer wall extending downwards into the liquid cavity is provided with a wiring port and an operation button. The wiring port connects to the mounting cavity, and the control component is connected to an external power supply line through the wiring port. The operation button is electrically connected to the control component.

[0029] Traditional insulated cups typically have two layers. Welding the mounting post to the cup wall poses a risk of vacuum leakage. The handle is usually attached to the outer cup wall via a ring-shaped fitting, which is aesthetically unappealing. This design, however, uses a third outer wall that is the cup wall outside the vacuum layer. The mounting post can be directly welded to this outer wall, connecting the handle and significantly improving both aesthetics and the overall strength of the connection.

[0030] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0031] (1) The outer wall can completely avoid the traces caused by welding of the outermost metal, maintain the integrated metallic feel of the outermost layer, and make the whole more beautiful. This can optimize the user experience and improve the sales prospects of manufacturers.

[0032] (2) The part connecting the outer wall and the interface section avoids the vacuum insulation layer formed by the inner wall and the vacuum wall, so that the connection of the outer wall will not damage the vacuum layer. For users, this ensures that the heat preservation performance of the heating cup is not affected. For manufacturers, the connection difficulty is reduced and production efficiency is improved because the outer wall avoids the vacuum layer during the production process. Furthermore, it avoids rework and material waste caused by vacuum leakage due to the connection of the outer wall, thus saving production costs. Attached Figure Description

Detailed Implementation

[0043] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0044] Example 1

[0045] refer to Figures 1 to 4 This embodiment provides a heating cup, including: a hollow cup body and a cup lid assembly 400 installed on the upper part of the cup body. The cup body includes: an inner wall 100 forming a liquid cavity 130; a vacuum wall 200 disposed outside the inner wall 100 and connected to the inner wall 100 to form a vacuum insulation layer 210; and an outer wall 300 sleeved outside the vacuum wall 200 and covering the vacuum wall 200. The outer wall 300 extends to the lower part of the liquid cavity 130 and forms a mounting cavity 310. A heating component and a control component are disposed in the mounting cavity 310. The heating component is connected to the liquid cavity 130. The control component is connected to the heating component and communicates with the outside through the outer wall 300. The vacuum insulation layer 210 acts on the side wall of the liquid cavity 130.

[0046] The liquid cavity 130 is used to hold liquid. The vacuum insulation layer 210 formed by connecting the vacuum wall 200 and the inner wall 100 plays a role in heat preservation of the liquid in the liquid cavity 130. The vacuum wall 200 and the inner wall 100 are usually connected by welding. The outer wall 300 can cover the welding marks left by polishing and oiling after welding on the vacuum wall 200, thereby making the overall appearance more beautiful, optimizing the user experience, and improving the sales prospects of manufacturers.

[0047] Compared to the inner wall 100 and vacuum wall 200 extending to form the mounting cavity 310, the outer wall 300 extending to form the mounting cavity 310 provides a larger space for the mounting cavity 310 to accommodate functional components.

[0048] The heating element is used to heat the liquid in the liquid cavity 130, and the control element is used to control the operation of the heating element, etc. The control element is connected to the outside for convenient user operation.

[0049] The inner wall 100 includes: a main body segment 110 forming a liquid cavity 130, the main body segment 110 forming an inlet at its upper part that connects the liquid cavity 130 to the outside; the upper end of the main body segment 110 extending upward to form an interface segment 120 away from the vacuum insulation layer 210; the upper end of the vacuum wall 200 connected to the lower part of the interface segment 120; the upper end of the outer wall 300 connected to the upper part of the interface segment 120; and a gap between the upper end of the vacuum wall 200 and the upper end of the outer wall 300.

[0050] The main body section 110 is the part that directly contacts the liquid, and the liquid enters and exits the liquid cavity 130 through the inlet. The upper end of the vacuum wall 200 is connected to the lower part of the interface section 120; the upper end of the outer wall 300 is connected to the upper part of the interface section 120; and there is a gap between the upper end of the vacuum wall 200 and the upper end of the outer wall 300. This allows the part where the outer wall 300 connects to the interface section 120 to avoid the vacuum insulation layer 210 formed by the inner wall 100 and the vacuum wall 200, so that the connection of the outer wall 300 will not damage the vacuum layer. For users, this ensures that the heat preservation performance of the heating cup is not affected; for manufacturers, since the outer wall 300 avoids the vacuum layer during the production process, the connection difficulty is reduced and the production efficiency is improved; furthermore, it avoids rework and material waste caused by vacuum leakage due to the connection of the outer wall 300, thus saving production costs.

[0051] The lower part of the inner wall 100 is provided with an annular lower extension plate 140; the upper part of the annular lower extension plate 140 is connected to the liquid cavity 130; the lower end of the vacuum wall 200 extends to the bottom of the liquid cavity 130 and is connected to the lower part of the annular lower extension plate 140; the annular lower extension plate 140 is provided with an extraction structure 141 for evacuating the vacuum insulation layer 210.

[0052] If the lower end of the vacuum wall 200 is directly connected to the main body section 110 of the inner wall 100, welding marks are easily left inside the liquid cavity 130, affecting the user's aesthetic experience. Therefore, connecting the vacuum wall 200 to the inner wall 100 via a lower extension plate keeps the interior of the liquid cavity 130 aesthetically pleasing, and eliminates the need for workers to consider the impact on the liquid cavity 130 during production, thus improving production efficiency.

[0053] Similarly, the vacuum extraction structure 141 is located on the lower extension plate, which helps maintain the aesthetic appearance of the liquid cavity 130. Furthermore, performing vacuum extraction on the lower extension plate is more convenient than performing it within the liquid cavity 130, further improving production efficiency.

[0055] The outer cover 420 forms an open container. The inner cover 410 includes: an inner liner 411, a snap-fit ​​member 412, and a top cover 413; the snap-fit ​​member 412 is sleeved on the outer side of the inner liner 411 and connected to the inner wall 100; the top cover 413 is connected to the top of the snap-fit ​​member 412.

[0056] The snap-fit ​​component 412 is also provided with a sealing component 414, which is used to abut against the edge of the inlet.

[0057] The inner liner 411, the snap-fit ​​component 412, and the top cover 413 are provided with a plurality of interconnected vent holes 415; the vent holes 415 form a ventilated channel that communicates with the outside of the inner cover 410; the ventilated channel is provided with a waterproof and ventilated component.

The flexible closure 320 includes a protruding ring 321 that abuts against the inner wall of the outer cover 420, and a protruding edge 322 that extends below the outer cover 420 and engages with the lower edge of the outer cover 420. The flexible closure 320 has an air guide channel. The air guide channel forms an avoidance recess 324 on the protruding edge 322 and an avoidance break 323 on the protruding ring 321. The air guide channel is used to connect the interior of the outer cover 420 with the exterior.

[0059] refer to Figure 4 The vacuum wall 200 is provided with a positioning protrusion 220 that abuts against the outer wall 300. The positioning protrusion 220 is preferably located at the lower part of the vacuum wall 200.

[0060] During production, the upper end of the outer wall 300 is first connected to the interface section 120 of the inner wall 100, while the lower end remains movable. The positioning protrusion 220 on the outer wall 300 abuts against it, preventing it from tilting or shifting. This greatly facilitates the connection of the lower end of the outer wall 300, improves production efficiency, and prevents an increase in the defect rate due to tilting at the lower end, saving materials and reducing production costs. Furthermore, the protrusion 321 makes the structure between the vacuum wall 200 and the outer wall 300 more compact, robust, and durable.
