Description

Technical Field

[0001] This invention relates to a scalding cup lid with temperature adjustment function, and more particularly to a scalding cup lid with temperature adjustment function that can adjust the temperature of beverages to a suitable drinking temperature through a temperature regulator, so as to prevent the drinker from being scalded by hot beverages. Prior Technology

[0002] Among various beverages, many require hot water to extract their flavor, such as coffee and tea. Others are consumed hot according to personal preference. Regardless, hot drinks are the preferred way for drinkers to enjoy them. However, these hot drinks can easily cause burns during consumption, such as scalding the hands and mouth, affecting the drinking experience. While insulation or handles can prevent hand burns in the container, the beverage itself remains at the high temperature of the brewing process, which can still cause injury to the mouth when consumed.

[0003] Generally, the main methods for cooling beverages are natural heat dissipation or the addition of cooling media to adjust the temperature. Firstly, natural heat dissipation refers to the gradual cooling of hot beverages at room temperature until they reach a temperature similar to the surrounding environment—a temperature that is not scalding hot, allowing the user to drink them with peace of mind. However, this takes a considerable amount of time, significantly diminishing the drinking experience for users who want to drink immediately. For rapid cooling, cooling media such as ice cubes can be added to quickly reach a suitable drinking temperature. However, these cooling media are not readily available and are often difficult to obtain for cooling operations when they are not easily portable.

[0004] In summary, while there are existing methods for cooling hot beverages, these methods are limited by waiting time or the required cooling medium, making it difficult to achieve a simple and rapid cooling effect. To address this, the inventors of this invention have conceived and designed a scald-proof cup lid with temperature adjustment functionality, aiming to improve upon the problems of conventional technologies and thereby enhance its industrial application. Summary of the Invention

[0005] In view of the problems of the prior art, the purpose of this invention is to provide a scalding cup lid with temperature adjustment function to solve the problem that hot beverages are difficult to cool to a suitable drinking temperature through a simple container.

[0006] According to one objective of the present invention, a scalding-proof cup lid with temperature adjustment function is provided, comprising a cup lid body, a temperature regulator, and an adjustment dial. The cup lid body is disposed on a beverage container and includes a bottom surface, a shell, and a top surface. The bottom surface has a beverage inlet, and the top surface has a beverage outlet. The beverage inlet and outlet are connected to a receiving space within the shell. The temperature regulator is disposed in the receiving space and includes a spiral pipe. One end of the spiral pipe is connected to the beverage inlet. The spiral pipe has a plurality of cooling nodes and a plurality of pipe openings corresponding to the plurality of cooling nodes, each connected to the beverage outlet. The adjustment dial is disposed on the top surface of the cup lid and has a plurality of gates corresponding to the plurality of pipe openings. The adjustment dial controls the opening or closing of the gates to adjust the spiral pipe's connection to the beverage outlet from one of the plurality of cooling nodes.

[0007] Preferably, the beverage inlet can be located at the edge or center of the bottom surface of the lid, and the beverage outlet can be located at the edge of the top surface of the lid.

[0008] Preferably, multiple pipe openings can be located at the top or side of the pipe wall of the spiral pipe.

[0009] Preferably, the plurality of gates may each have a control element and a blocking element. The control element is connected to an adjustment dial, and the blocking element is connected to the control element and blocks the plurality of pipe openings. When the adjustment dial is rotated to one of the positions of the plurality of gates, the corresponding control element moves the blocking element to expose one of the plurality of pipe openings.

[0010] Preferably, the temperature regulator can be configured with a plurality of cooling chips, each located at a plurality of cooling nodes.

[0011] Preferably, the adjustment dial can be equipped with a plurality of switches, which are connected to a plurality of cooling wafers. The adjustment dial controls the opening of the plurality of switches, thereby driving the plurality of cooling wafers to cool the plurality of nodes.

[0012] Preferably, the spiral pipe can be equipped with 3 cooling nodes.

[0013] Preferably, the cooling temperature between the plurality of cooling nodes is approximately 5°C to 10°C.

[0014] Preferably, the spiral pipe can be equipped with 5 cooling nodes.

[0015] Preferably, the cooling temperature between the plurality of cooling nodes is approximately 3°C to 8°C.

[0016] As described above, the anti-scalding cup lid with temperature adjustment function according to the present invention may have one or more of the following advantages:

[0017] (1) This anti-scalding cup lid with temperature adjustment function can cool down the beverage by letting it flow through the spiral pipe of temperature adjustment gas. When the beverage flows out of the beverage outlet of the cup lid, it is at a suitable drinking temperature, which improves the drinking experience and avoids the risk of scalding caused by high temperature.

[0018] (2) This anti-scalding cup lid with temperature adjustment function can adjust the degree of beverage cooling by adjusting the dial. That is, the length of the beverage flowing through the spiral tube is defined by different cooling nodes, thereby achieving the effect of controlling the cooling range. This allows users to select different cooling ranges through simple operation, increasing the applicability to different temperatures or beverage types.

[0019] (3) This anti-scalding cup lid with temperature adjustment function can reduce the temperature of the beverage through the structure inside the cup lid. It is suitable for various beverage containers and does not require carrying coolant or other additional media, increasing the convenience of use and improving the user's drinking experience by providing the best drinking temperature.

[0021] To facilitate understanding of the technical features, content, advantages, and effects of this invention, the invention is described in detail below with reference to the accompanying drawings and embodiments. The drawings used are for illustrative purposes only and to assist in the description. They may not represent the actual proportions and precise configurations of the invention after implementation. Therefore, the proportions and configurations of the accompanying drawings should not be used to interpret or limit the scope of the invention in actual implementation. This should be stated in advance.

[0022] Please refer to Figure 1, which is a schematic diagram of a heat-adjustable anti-scalding cup lid according to an embodiment of the present invention. As shown in the figure, the heat-adjustable anti-scalding cup lid 10 includes a lid body 11, a temperature regulator 21, and an adjustment dial 31. The lid body 11 is cylindrical and is mounted on a beverage container 90, serving as a lid to cover the mouth of the beverage container 90 to prevent beverage spillage. The lid body 11 includes a bottom surface 12, a lid shell 13, and a top surface 14, which can be made of plastic or metal. The bottom surface 12 contacts the rim of the beverage container 90. A beverage inlet 15 is provided at the edge of the bottom surface 12. When the user tilts the beverage container 90, the beverage flows from the beverage inlet 15 into the receiving space 16 inside the lid shell 13. A beverage outlet 17 is provided at the edge of the top surface 14. The beverage inlet 15 and the beverage outlet 17 are connected to the receiving space 16 inside the lid shell 13, and the beverage flows out through the beverage outlet 17 for the user to drink.

[0023] Users often prefer hot beverages such as coffee, tea, and soy milk. These drinks are frequently too hot to drink comfortably, especially when drinking through the lid. Because the lid covers the beverage, users cannot easily perceive the temperature, increasing the risk of burns when the drink flows from the spout 17. To address this issue, this invention discloses a temperature regulator 21 within the lid body 11 to appropriately cool the beverage, ensuring it flows out at the optimal drinking temperature.

[0024] A temperature regulator 21 is disposed within the accommodating space 16. The temperature regulator 21 is provided with a spiral pipe 22. Please also refer to Figure 2, which is a schematic diagram of the temperature regulator according to an embodiment of the present invention. As shown in the figure, one end of the spiral pipe 22 is connected to the beverage inlet 15. The spiral pipe 22 is provided with a plurality of cooling nodes and a plurality of pipe openings corresponding to the plurality of cooling nodes. In this embodiment, the spiral pipe 22 is provided with five cooling nodes, namely a first cooling node 23A, a second cooling node 23B, a third cooling node 23C, a fourth cooling node 23D, and a fifth cooling node 23E, corresponding to the first pipe opening 24A, the second pipe opening 24B, the third pipe opening 24C, the fourth pipe opening 24D, and the fifth pipe opening 24E. In this embodiment, the pipe openings are located at the top of the pipe wall of the cooling nodes, but this disclosure is not limited to this. In other embodiments, the pipe openings may also be located on the side of the pipe wall of the cooling nodes.

[0025] After the beverage flows in through the beverage inlet 15, it flows along the spiral pipe 22, which can be made of a heat-dissipating metal material. After flowing a predetermined distance, the beverage is moderately cooled. For example, between five cooling nodes, the temperature drop between each node is approximately 3°C to 8°C, and the beverage temperature can be reduced by approximately 15°C to 40°C through the five nodes. Therefore, when the hot beverage flows out through the beverage outlet 17, the temperature can be reduced to a suitable drinking temperature, preventing burns to the drinker and improving the satisfaction of the drinking process.

[0026] Because the spiral pipe 22 has multiple heat dissipation nodes, the cooling range can be adjusted by flowing through different numbers of nodes. To control the temperature adjustment, an adjustment turntable 31 is provided on the top surface 14 of the cup lid. Please also refer to Figure 3, which is a schematic diagram of the adjustment turntable in an embodiment of the present invention. As shown in the figure, the adjustment turntable 31 is a circular turntable slightly smaller than the top surface 14 of the cup lid, and its circumference can be provided with a serrated shape to facilitate the user to rotate this adjustment turntable 31 to the set position. The adjustment turntable 31 has multiple gates, which correspond to multiple pipe openings. The adjustment turntable 31 controls the opening or closing of the multiple gates. In this embodiment, five gates are provided corresponding to the five cooling nodes. Each gate has a control element 32 and a blocking element 33. The control element 32 is connected to the adjustment turntable 31, and the blocking element 33 is connected to the control element 32 and blocks a plurality of pipe openings. When the adjustment turntable 31 is rotated to one of the positions of the plurality of gates, the corresponding control element 32 moves the blocking element 33 to expose one of the plurality of pipe openings. For example, when the adjustment turntable 31 is rotated to scale A, the control element 32 moves the blocking element 33 on the first cooling node 23A, so that the first pipe opening 24A is exposed. The beverage enters the receiving space 16 through the first pipe opening 24A and then flows out from the beverage outlet 17 for the user to drink. If the dial is rotated to scale B, the control element 32 removes the blocking element 33 on the second cooling node 23B, exposing the second pipe opening 24B. The beverage flows through the first cooling node 23A and the second cooling node 23B, then enters the receiving space 16 through the second pipe opening 24B, and finally flows out from the beverage outlet 17 for the user to drink. The same principle applies to other components; by controlling the length of the beverage flowing through the spiral pipe 22, the cooling temperature range is adjusted to ensure the beverage reaches the optimal drinking temperature.

[0027] Please refer to Figure 4, which is a schematic diagram of a scalding-proof cup lid with temperature adjustment function according to another embodiment of the present invention. As shown in the figure, the scalding-proof cup lid 40 with temperature adjustment function includes a cup lid body 41, a temperature regulator 51, and an adjustment dial 61. The cup lid body 41 is cylindrical and is disposed on the beverage container 91, serving as a cup lid that covers the mouth of the beverage container 91 to prevent beverage from overflowing. The cup lid body 41 includes a cup lid bottom surface 42, a cup lid shell 43, and a cup lid top surface 44, which can be made of plastic or metal. The cup lid bottom surface 42 contacts the rim of the beverage container 91. A beverage inlet 45 is provided in the center of the cup lid bottom surface 42. When the user tilts the beverage container 91, the beverage in it flows into the receiving space 46 inside the cup lid shell 43 through the beverage inlet 45. A beverage outlet 47 is provided at the edge of the cup lid top surface 44. The beverage inlet 45 and the beverage outlet 47 are connected to the receiving space 46 inside the cup lid shell 43, and the beverage flows out through the beverage outlet 47 for the user to drink.

[0028] Similar to the aforementioned embodiments, hot beverages can easily cause burns. Therefore, a temperature regulator 51 is installed inside the cup lid body 41 to moderately cool the beverage, ensuring it flows out at the optimal drinking temperature. Please also refer to Figure 5, which is a schematic diagram of a temperature regulator according to another embodiment of the present invention. As shown, the temperature regulator 51 has a spiral pipe 52, one end of which is connected to the beverage inlet 45. The spiral pipe 52 has a plurality of cooling nodes and a plurality of pipe openings corresponding to the plurality of cooling nodes. In this embodiment, the spiral pipe 52 has three cooling nodes: a first cooling node 53A, a second cooling node 53B, and a third cooling node 53C, corresponding to a first pipe opening 54A, a second pipe opening 54B, and a third pipe opening 54C. In this embodiment, the pipe openings are located at the top of the cooling node's pipe wall, but this disclosure is not limited to this; in other embodiments, the pipe openings may also be located on the side of the cooling node's pipe wall.

[0029] After the beverage flows in through the beverage inlet 45, it flows along the spiral pipe 52, which can be made of a heat-dissipating metal material. After flowing a predetermined distance, the beverage is moderately cooled. For example, between three cooling nodes, the temperature drop between each node is approximately 5°C to 10°C, and the beverage temperature can be reduced by approximately 15°C to 30°C through the three nodes. Therefore, when the hot beverage flows out through the beverage outlet 47, the temperature can be reduced to a suitable drinking temperature, preventing burns to the drinker and improving the satisfaction of the drinking process.

[0030] Because the spiral pipe 52 has multiple heat dissipation nodes, the cooling range can be adjusted by flowing through different numbers of nodes. For temperature control, an adjustment dial 61 is provided on the top surface 44 of the cup lid. Please also refer to Figure 6, which is a schematic diagram of the adjustment dial in another embodiment of the present invention. As shown, the adjustment dial 61 is a circular dial slightly smaller than the top surface 44 of the cup lid, and its circumference can be serrated to facilitate the user's rotation of the adjustment dial 61 to the set position. The adjustment dial 61 has multiple gates, each corresponding to a multiple pipe opening. The adjustment dial 61 controls the opening or closing of the multiple gates. In this embodiment, three gates are provided corresponding to the three cooling nodes. Each gate has a control element 62 and a blocking element 63. The control element 62 is connected to the adjustment turntable 61, and the blocking element 63 is connected to the control element 62 and blocks a plurality of pipe openings. When the adjustment turntable 61 is rotated to one of the positions of the plurality of gates, the corresponding control element 62 moves the blocking element 63 to expose one of the plurality of pipe openings. For example, when the adjustment turntable 61 is rotated to scale A, the control element 62 moves the blocking element 63 on the first cooling node 53A, exposing the first pipe opening 54A. The beverage enters the receiving space 46 through the first pipe opening 54A and then flows out from the beverage outlet 47 for the user to drink. If the dial is rotated to scale B, the control unit 62 removes the blocking member 63 on the second cooling node 53B, exposing the second pipe opening 54B. The beverage flows through the first cooling node 53A and the second cooling node 53B, then enters the receiving space 46 through the second pipe opening 54B, and finally flows out from the beverage outlet 47 for the user to drink. The same principle applies to other components; by controlling the length of the beverage flowing through the spiral pipe 52, the cooling temperature range is adjusted to ensure the beverage reaches the optimal drinking temperature.

[0031] In this embodiment, the temperature regulator 51 may further be provided with a plurality of cooling chips 55, which are respectively disposed at the positions of a plurality of cooling nodes, for example, cooling chips 55 are disposed on the sides of the first cooling node 53A, the second cooling node 53B, and the third cooling node 53C. A switch is provided for each cooling chip 55, and the switch is connected to an adjustment dial 61. When the adjustment dial 61 rotates to the scale of the corresponding node, the adjustment dial 61 drives the switch to activate the corresponding cooling chip 55, driving the plurality of cooling chips 55 to cool the plurality of nodes. For example, when the adjustment dial 61 rotates to scale C, in addition to the control member 62 removing the blocking member 63 on the third cooling node 53C to expose the third pipe opening 54C, the cooling chips 55 of the three nodes are activated simultaneously, so that when the beverage passes through the first cooling node 53A, the second cooling node 53B, and the third cooling node 53C, it can be further cooled to reach the expected drinking temperature.

[0032] In this disclosure, three nodes and five nodes are used as examples to illustrate different temperature regulation ranges. However, the number and position of the nodes are not limited to the embodiments described herein. In other embodiments, the number and position of the nodes in the spiral pipe can be adjusted according to requirements such as the size of the cup lid and the cooling range.
