Description

Technical Field

[0001] This utility model relates to the field of containers for holding liquids, and in particular to a beverage container and a heating mechanism for the beverage container. Background Technology

[0002] A mug is a common household cup, generally used for holding hot beverages such as milk, coffee, and tea. The body of a mug is typically a standard cylinder or near-cylindrical shape, and it usually has a handle on one side. Currently, mugs on the market include single-walled and multi-walled mugs. Single-walled mugs have good heat dissipation, but in low-temperature environments, the liquid inside will lose heat quickly, making it impossible to maintain the liquid's temperature. Multi-walled mugs, on the other hand, have a heating element that helps maintain the temperature of the liquid inside.

[0003] In the prior art, after the mug body and the heating module are connected by a connecting structure, due to processing or assembly errors, there are problems such as poor contact between the bottom surface of the mug body and the heating surface of the heating module, resulting in a long heating time for the liquid inside the mug. In some cases, the bottom surface of the mug body and the heating surface of the heating module cannot make contact at all, so the heat cannot be transferred to the mug body, and the heating module cannot dissipate heat and is damaged. Utility Model Content

[0004] In view of this, the present invention provides a heating mechanism for a beverage container, which ensures that the bottom of the container placed on the heating component is always in close contact with the heating surface of the heating component, thereby improving heat transfer efficiency and extending the service life of the heating component.

[0005] This utility model also provides a beverage container.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heating mechanism for a beverage container includes at least a shell, a PCB board, a power supply, a heating component, and an elastic component. The top of the shell has an opening, the heating component is disposed in the opening, and there is a gap between the heating component and the shell. The elastic component is at least partially disposed in the gap, and the elastic component allows the heating component to move up and down within a set range.

[0008] The PCB board and the power supply are located inside the housing. The heating component is electrically connected to the PCB board, and the PCB board is electrically connected to the power supply.

[0009] Optionally, the heating assembly includes stacked heat-conducting sheets and heating sheets, the heating sheets being disposed on the lower surface of the heat-conducting sheets and the heat-conducting sheets being disposed above the support inside the opening;

[0010] The elastic component includes an elastic silicone ring and / or a spring.

[0011] Optionally, the elastic silicone ring is disposed on the outer periphery of the heat-conducting sheet.

[0012] Optionally, the two ends of the spring abut against the bracket and the elastic silicone ring, respectively.

[0013] Optionally, it also includes a heat insulation component disposed between the bracket and the heating element;

[0014] The thermal insulation assembly includes stacked thermal insulation cotton and mica sheets.

[0015] Optionally, the plurality of springs are evenly distributed around the axis of the bracket.

[0016] Optionally, the elastic silicone ring is injection molded to the thermal conductive sheet.

[0017] Optionally, the edge of the heat-conducting sheet is provided with a stepped flange, and the elastic silicone ring is wrapped around the stepped flange;

[0018] The stepped flange is provided with a plurality of connecting holes, which are evenly distributed on the stepped flange.

[0019] Optionally, the inner side of the elastic silicone ring is connected to the bracket, and the outer side is connected to the outer shell, and the spring is disposed between the bottom of the bracket and the outer shell.

[0020] Optionally, a heat insulation component is fixedly connected to the surface of the heating element away from the heat-conducting sheet.

[0021] Optionally, the PCB board is disposed at the bottom of the bracket, one end of the spring is connected to the PCB board, and the other end is connected to the bottom surface of the opening of the housing.

[0022] As can be seen from the above technical solution, the heating mechanism for the beverage container provided by this utility model, by setting the elastic component and the heating component connected together, allows the heating component to move up and down within a set range, thereby enabling the heating component to float up and down along the axial direction. This allows the heating component to move with the displacement of the bottom of the container placed on it, ensuring that the bottom of the container placed on the heating component is always in close contact with the surface of the heating component. This achieves reliable contact between the bottom surface of the container and the heating surface of the heating component, allowing more heat emitted by the heating component to be transferred to the bottom surface of the container, improving heat transfer efficiency, avoiding damage to the heating component due to the inability to dissipate heat, and extending the service life of the heating component.

[0023] This utility model also provides a beverage container, including a container body and a heating mechanism. The heating mechanism is the same as that of the beverage container described above, and the container body is placed on the heating component of the heating mechanism. The beverage container of this utility model has the aforementioned heating mechanism and therefore possesses the advantages of such a mechanism, which will not be elaborated further here.

[0042] This utility model discloses a heating mechanism for a beverage container, which ensures that the bottom of the container placed on the heating component is always in close contact with the heating surface of the heating component, thereby improving heat transfer efficiency and extending the service life of the heating component.

[0043] This utility model also discloses a beverage container.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] See Figures 1 to 10 The heating mechanism 2 of the beverage container of this utility model includes at least a shell 208, a PCB board 213, a power supply, a heating component, and an elastic component. The top of the shell 208 has an opening, and the heating component is disposed within the opening. A gap exists between the heating component and the shell 208, and the elastic component is at least partially disposed within the gap, allowing the heating component to move up and down within a set range. The heating component is electrically connected to the PCB board 213, and the PCB board 213 is electrically connected to the power supply.

[0046] The heating component is mounted on the elastic component. A gap is provided between the heating component and the outer casing 208 to facilitate the vertical movement of the heating component. The power source is a battery.

[0047] The heating mechanism 2 of this utility model for a beverage container, by setting an elastic component and a heating component connected together, allows the heating component to move up and down within a set range, thereby enabling the heating component to float up and down along the axial direction. This allows the heating component to move with the displacement of the bottom of the container placed on it, ensuring that the bottom of the container placed on the heating component is always in close contact with the surface of the heating component. This achieves reliable contact between the bottom surface of the container and the heating surface of the heating component, allowing more heat emitted by the heating component to be transferred to the bottom surface of the container, improving heat transfer efficiency, avoiding damage to the heating component due to the inability to dissipate heat, and extending the service life of the heating component.

[0048] Specifically, refer to Figures 4 to 6 As shown, the heating assembly includes stacked heat-conducting plates 205 and heating elements 211. The heating element 211 is disposed on the lower surface of the heat-conducting plate 205, which is positioned above a support 207 within the opening. The support 207 supports the heat-conducting plate 205. The heating element 211 provides heat, and the heat-conducting plate 205 contacts it, transferring the heat from the heating element 211 to the container, thereby heating the liquid inside. The elastic component includes an elastic silicone ring 204 and a spring 206. The spring 206 provides axial movement force for the heat-conducting plate 205, and the elastic silicone ring 204 seals the gap between the moving and stationary parts, i.e., the gap between the heating assembly and the outer casing 208, without restricting the axial displacement of the heat-conducting plate 205. The spring 206 can be a helical spring or other types of springs, which are not limited here.

[0049] In one embodiment, reference is made to Figures 2 to 9 The heat-conducting plate 205 is fixedly connected to the inner side of the elastic silicone ring 204, and the outer side of the elastic silicone ring 204 is fixedly mounted on the top of the bracket 207. Specifically, the outer side of the elastic silicone ring 204 is positioned against the outer shell 208 by the bracket 207 that is pressed and installed at the top. Figure 6 As shown, the bracket 207 supports the bottom of the outer portion of the elastic silicone ring 204, and the housing 208 is suspended at the opening position, pressing the top of the outer portion of the elastic silicone ring 204 against the protrusion.

[0050] The bracket 207 is equipped with a spring 206, the top of which contacts the bottom of the elastic silicone ring 204 near its inner side. To limit the movement of the spring 206, the bracket 207 is provided with a spring placement hole 2072. Figure 8 and Figure 9 As shown, spring 206 is disposed within spring placement hole 2072. The top end of spring 206 contacts the bottom of elastic silicone ring 204, and the bottom end contacts the bottom surface of spring placement hole 2072. To ensure reliable contact between the top end of spring 206 and elastic silicone ring 204, the axial height of spring 206 is greater than the height of spring placement hole 2072. The expansion and contraction properties of spring 206 allow heat-conducting plate 205 to move up and down.

[0051] To achieve heat insulation, the heating mechanism 2 of the beverage container of this utility model further includes a heat insulation component, which is disposed between the support 207 and the heating element 211. By setting the heat insulation component, both the ineffective loss of heat from the heating element 211 and the impact of high temperature on other components such as the PCB board 213 can be avoided. Specifically, the heat insulation component includes stacked heat insulation cotton 209 and mica sheet 210. The heat insulation cotton 209 is placed on the supporting convex surface 2076 of the support 207, and the mica sheet 210 is disposed between the heating element 211 and the heat insulation cotton 209. The upper surface of the mica sheet 210 is connected to the heating element 211, and the lower surface is in contact with or connected to the heat insulation cotton 209. The mica sheet 210 and the heat insulation cotton 209 can be connected together or not, which is not limited here. The mica sheet 210 is located on the lower surface of the heating element 211 and plays a role in heat insulation. The heat insulation cotton 209 is located below the mica sheet 210. It not only utilizes the heat insulation function, but also the elasticity of the heat insulation cotton. When the heating surface of the heating element 211 moves downward, the heat insulation cotton 209 absorbs this displacement. That is, the heat insulation cotton 209 absorbs this displacement through its own compression.

[0052] Among them, such as Figure 8 and Figure 9 As shown, a supporting convex surface 2076 is located at the center of the bracket 207, coinciding with the center of the bracket 207. The supporting convex surface 2076 supports the heat insulation cotton 209, mica sheet 210, heating element 211, and heat-conducting sheet 205. An annular groove 2071 is provided around the supporting convex surface 2076, corresponding to the bottom end of the elastic silicone ring 204. A spring placement hole 2072 is located within the annular groove 2071. The width of the annular groove 2071 is greater than the dimension of the bottom end of the elastic silicone ring 204 along the width direction of the annular groove 2071, thus facilitating the pressing of the bottom end of the elastic silicone ring 204 onto the spring 206. The diameter of the spring placement hole 2072 is slightly larger than the outer diameter of the spring 206, facilitating the installation of the spring 206.

[0053] To improve the support stability of the elastic silicone ring 204, multiple springs 206 are provided, and correspondingly, multiple spring placement holes 2072 are also provided. The number of springs 206 is the same as the number of spring placement holes 2072, with one spring 206 placed in each spring placement hole 2072. The multiple spring placement holes 2072 are evenly distributed around the axis of the bracket 207. One end of each spring 206 contacts the elastic silicone ring 204, and the other end contacts the bottom surface of the spring placement hole 2072; that is, both ends of the spring 206 are free ends and do not need to be connected.

[0054] To facilitate a reliable connection between the elastic silicone ring 204 and the heat-conducting sheet 205, the elastic silicone ring 204 is injection molded to the edge of the heat-conducting sheet 205. To increase the connection area at the injection point and improve the reliability of the connection, the edge of the heat-conducting sheet 205 is provided with a stepped flange, such as... Figure 6 and Figure 7 As shown, an elastic silicone ring 204 is fitted around the stepped flange. The stepped flange has multiple connecting holes, as shown in the reference diagram. Figure 7 The connecting hole is an elongated through hole, and multiple connecting holes are evenly arranged on the stepped flange. After injection molding, the connecting hole is also filled with silicone material, thereby reliably connecting the heat-conducting sheet 205 to the elastic silicone ring 204.

[0055] To facilitate the detection of the temperature of the bottom surface of the heated container, a temperature sensor 203 is installed on the heat-conducting sheet 205. Openings or holes are provided on the heating element 211, mica sheet 210, insulation cotton 209, and bracket 207 at positions corresponding to the temperature sensor 203, allowing the temperature sensor 203 to pass through. Specifically, the bracket 207 has a first through-hole 2075 and a second through-hole 2073. The first through-hole 2075 allows the temperature sensor 203 to pass through, and the second through-hole 2073 allows the PCB connector on the heating element 211 to pass through. The bracket 207 is also provided with a connecting leg 2077 and a connecting arm 2074. The connecting leg 2077 passes through the PCB board 213 and connects to the bottom of the opening of the housing 208. The connecting arm 2074 connects to the side wall of the housing 208. This structure is suitable for limiting the structure where the bottom surface and the side wall of the housing 208 are separate. If the bottom surface and the side wall of the housing 208 are an integral structure, only one of the connecting leg 2077 and the connecting arm 2074 needs to be provided.

[0056] In one embodiment, the beverage container used for the heating mechanism 2 is a cup body 1, which includes an inner liner 102 and a bottom cover 103. The bottom cover 103 is fixedly connected to the bottom of the inner liner 102. Figures 1 to 3To facilitate the connection between the cup body 1 and the heating mechanism 2, a first thread 101 is provided on the inner side of the cup bottom cover 103 of the cup body 1, and a second thread 201 that mates with the first thread 101 is provided on the outer side of the outer shell 208. The cup body 1 and the heating mechanism 2 are threadedly connected through the first thread 101 and the second thread 201. In other embodiments, the connection between the cup body 1 and the heating mechanism 2 can also adopt other connection methods, such as snap-fit ​​connection, plug-in connection, etc., which are not limited here.

[0057] To facilitate the connection between the heating mechanism 2 and the charging module 3, a first insertion part 202 is provided on the outer side of the housing 208 near the bottom. A placement groove 303 is provided on the surface of the charging module 3 near the housing 208, and a second insertion part 302 is provided on the side wall of the placement groove 303. The first insertion part 202 and the second insertion part 302 are correspondingly inserted into each other, thereby enabling the bottom of the housing 208 to be inserted into the charging module 3. A suction cup 301 is provided on the bottom surface of the charging module 3. By providing the suction cup 301, the charging module 3 can be easily adsorbed onto the placement surface, improving placement stability. Other structures of the charging module 3 are commonly used in the prior art and will not be described in detail here.

[0058] Specifically, the first insertion part 202 is a recessed platform disposed on the outer side of the outer casing 208, such as Figure 3 As shown, the second insertion part 302 is a boss provided on the side wall of the groove where the groove 303 is placed, and the boss and the recess are inserted into each other along the axial direction of the outer shell 208.

[0059] When the cup body 1 is connected to the heating mechanism 2, the bottom of the inner liner 102 contacts the heat-conducting plate 205 and continues to move downwards by a certain amount of travel. At this time, the heating element 211 and mica sheet 210 below the heat-conducting plate 205 also move downwards. The bottom of the insulation cotton 209 is supported by the bracket 207, and the insulation cotton 209 absorbs this travel by its own compression. One side of the elastic silicone ring 204 connected to the heat-conducting plate 205 moves downwards due to the movement of the heat-conducting plate 205, compressing the spring 206. When the cup body 1 is removed, the spring 206 releases its compression, causing the elastic silicone ring 204 and the heat-conducting plate 205 to move upwards, and at the same time, the heating element 211 and other parts move upwards, returning to their initial state.

[0060] In another embodiment, reference Figure 10 A heat-conducting plate 205 is disposed at the top of a bracket 207. An elastic silicone ring 204 is fitted around the edge of the bracket 207. The inner side of the elastic silicone ring 204 is fixedly connected to the bracket 207, and the outer side is connected to the outer shell 208. Specifically, as shown... Figure 10As shown, an elastic silicone ring 204 is positioned near the top of the bracket 207. The bottom of the bracket 207 is connected to the PCB board 213, which is connected to the spring 206. The spring 206 is located at the bottom of the opening in the housing 208. In this embodiment, multiple springs 206 are provided to improve the stability of the support. One end of the spring 206 is connected to the PCB board 213, and the other end is connected to the bottom surface of the opening in the housing 208.

[0061] To improve sealing performance and prevent external dust or liquid from entering the inner cavity of the opening in the housing 208, a sealing ring 212 is provided at the connection position between the bracket 207 and the heat-conducting plate 205.

[0062] In this embodiment, the heating element 211 is fixedly connected to the heat-conducting sheet 205, and a heat insulation component is fixedly connected to the surface of the heating element 211 away from the heat-conducting sheet 205. The heat insulation component is heat insulation cotton 209, which is fixedly connected to the heating element 211.

[0063] In this embodiment, when the container, such as the cup body 1, is placed on the heat-conducting plate 205, the elastic silicone ring 204 deforms as the heat-conducting plate 205 moves downward. The side of the ring closer to the heat-conducting plate 205 moves downward along with it, while the side farther away from the heat-conducting plate 205 remains fixed on the outer shell 208, maintaining its position. Simultaneously, the PCB board 213 moves downward, and the spring 206 is compressed. After the cup body 1 is removed, the heat-conducting plate 205 returns to its initial state under the combined restoring force of the spring 206 and the elastic silicone ring 204.

[0064] The heating mechanism 2 of the beverage container of this utility model is provided with a matching elastic silicone ring 204 and spring 206. The extension and retraction of the spring 206 causes the heat-conducting plate 205 to float up and down, so that the heat-conducting plate 205 and the heating plate 211 can move up and down with the bottom displacement of the container, thereby ensuring that the heating surface of the heating mechanism 2 is in close contact with the bottom surface of the container and improving the heat transfer efficiency.

[0065] This utility model also provides a beverage container, including a container body, a heating mechanism, and a charging module 3. The container body is placed on the heating mechanism, and the heating mechanism is placed on the charging module 3. The heating mechanism is the heating mechanism 2 of the beverage container described above, and the container body is a cup body 1. (Refer to...) Figure 1 As shown, the cup body 1 is connected to the heating mechanism 2, the heating mechanism 2 is connected to the charging module 3, and the charging module 3 is connected to an external power socket via a plug to provide power to the heating module 2. This connection is detachable.
