Description

Technical Field

[0001] The present application belongs to the technical field of drinking utensils, and specifically relates to a multifunctional thermos cup. Background Art

[0002] With the improvement of living standards, people's awareness of health and wellness has gradually increased, and they are more inclined to drink warm water to keep their bodies hydrated. When traveling, more and more people, including young people, begin to carry thermos cups so that they can drink warm water outside. However, due to the high temperature of the water, it usually takes a long time to wait for the water temperature in the thermos cup to drop to a palatable temperature before drinking. When people have an urgent need to drink water, they cannot drink warm water of suitable temperature in time, or when people stay outdoors for a long time, the water temperature in the thermos cup gradually drops until it is lower than the palatable temperature required by the user, resulting in a poor user experience of the thermos cup.

[0003] In order to solve this problem, the prior art discloses a water cup with a rapid cooling function. A straw with a two-layer structure is arranged in the cavity of the water cup. The inner layer of the straw is a water absorption layer, and the outer layer is a cooling layer. After the hot water is absorbed, the temperature is reduced by the cooling effect of the straw cooling layer to meet the drinking needs of the user. However, in this solution, the cooling is achieved by exchanging heat between the hot water and the air. Therefore, the cooling layer can only cool the hot water, and cannot heat the low-temperature water. In addition, the cooling layer also absorbs heat from the hot water in the cup. The hot water in the water cup continues to accelerate the heat dissipation under the action of the cooling layer, which affects the thermal insulation performance of the water cup.

[0019] 1. The thermos cup of the present application comprises an upper cup body with an upper chamber, a lower cup body with a lower chamber, and a partition separating the upper chamber from the lower chamber, wherein the lower chamber is used to hold liquid, and the upper chamber is used to hold heat exchange medium. The user sucks the liquid in the lower chamber through a straw, and the liquid reaches a palatable temperature under the action of the heat exchange medium after passing through the upper chamber and is drunk by the user. Since the upper chamber and the lower chamber are separated by the partition, the heat exchange effect of the heat exchange medium in the upper chamber on the liquid in the lower chamber is greatly weakened, thereby ensuring the thermal insulation performance of the thermos cup to the greatest extent; in addition, the user can heat up or cool down the liquid in the lower chamber by changing the type of heat exchange medium in the upper chamber.

[0021] 3. As a preferred embodiment of the present invention, by providing a first seal and sealing the partition against the first seal in the circumferential direction, the circumferential diffusion of heat transferred from the upper cup body to the partition is reduced, thereby reducing the impact on the temperature of the liquid in the lower chamber; the upper cup body and the lower cup body are respectively sealed against the first seal in the up and down directions, thereby reducing the risk of liquid in the upper and lower chambers leaking through the joints between the upper and lower cup bodies and the connecting piece, which helps to improve the airtightness of the thermos cup.

[0022] 4. As a preferred embodiment of the present invention, a positioning ring is provided and the first seal is inserted into the positioning ring along the radial direction of the first seal, so that the positioning ring and the first seal jointly bear the gravity of the heat exchange medium in the upper chamber, thereby reducing the bearing pressure of the first seal, thereby reducing the risk of deformation of the first seal causing the partition to shift and fall off. The downward projection of the lower edge of the upper cup body is located within the horizontal projection range of the positioning ring, which further increases the bearing area of ​​the positioning ring and further reduces the bearing pressure of the positioning ring and the first seal.

[0023] 5. As a preferred embodiment of the utility model, the upper cup body and the lower cup body are connected to the connecting parts by threaded connection, which makes the disassembly and assembly of the upper cup body and the lower cup body more convenient.

[0024] Furthermore, by respectively providing an upper stop step and a lower stop step on the upper cup body and the lower cup body, when the lower cup body and the upper cup body are screwed into place, the upper stop step and the lower stop step will abut against the connecting piece, so that the upper cup body and the lower cup body cannot be screwed any further, thereby avoiding deformation of the upper cup body, the lower cup body and the connecting piece caused by excessive screwing; in addition, when the user screws until the upper stop step abuts against the top of the connecting piece or the lower stop step abuts against the bottom of the connecting piece, there will be an obvious sense of being in place, prompting the user that the upper cup body or the lower cup body has been screwed into place, so that the user can know the screwing status of the upper cup body and the lower cup body without observing the screwing status of the upper cup body and the lower cup body, thereby improving the convenience of user use.

[0025] 6. As a preferred embodiment of the present invention, the thermos cup further comprises a second seal provided at the connecting port, and the first straw section and the second straw section are respectively abutted and sealed against the second seal. By providing the second seal, the connecting port is sealed, and the heat exchange between the heat exchange medium in the upper chamber and the water in the lower chamber is further reduced, thereby providing a guarantee for the heat preservation performance of the thermos cup; in addition, the second seal can also prevent the liquid in the upper chamber and the lower chamber from leaking at the connecting port during the assembly of the upper cup body, the lower cup body and the connector, thereby improving the sealing performance of the thermos cup.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0047] like Figures 1 to 6 As shown, a multifunctional thermos cup comprises: a lower cup body 2, wherein the lower cup body 2 is provided with a lower chamber (not shown in the figure); an upper cup body 1, wherein the upper cup body 1 is provided with an upper chamber 11, and the upper cup body 1 is provided with a drinking port; a partition 3, which is used to separate the lower chamber and the upper chamber 11, and the partition 3 is provided with a connecting port; a straw 4 passing through the connecting port, wherein the straw 4 comprises a first straw segment 41 and a second straw segment 42 which are connected to each other, wherein at least a part of the first straw segment 41 is located in the lower chamber, and at least a part of the second straw segment 42 is located in the upper chamber 11, and the liquid in the lower chamber flows out of the drinking port after passing through the upper chamber 11 through the first straw segment 41 and the second straw segment 42.

[0048] In one embodiment, the first straw segment 41 and the second straw segment 42 are integrally formed structures, and the straw 4 passes through the connecting port so that the portion located in the upper chamber 11 becomes the second straw segment 42 , and the portion located in the lower chamber becomes the first straw segment 41 .

[0049] In another embodiment, the first straw segment 41 and the second straw segment 42 are separately formed structures. As a preferred example under this embodiment, the top end of the first straw segment 41 and the bottom end of the second straw segment 42 are respectively inserted into the connecting port to achieve docking and connection between the two at the connecting port. Of course, this embodiment is not limited to this. In another example, the bottom end of the second straw segment 42 can be further extended downward so that it can extend into the lower chamber, and the first straw segment 41 and the second straw segment 42 are docked and connected in the lower chamber.

[0050] The thermos cup of the present application comprises an upper cup body 1 having an upper chamber 11, a lower cup body 2 having a lower chamber, and a partition 3 separating the upper chamber 11 from the lower chamber, wherein the lower chamber is used to hold liquid, and the upper chamber 11 is used to hold a heat exchange medium. The user absorbs the liquid in the lower chamber through a straw 4, and the liquid reaches a palatable temperature under the action of the heat exchange medium after passing through the upper chamber 11 and is drunk by the user. Since the upper chamber 11 is separated from the lower chamber by the partition 3, the heat exchange effect of the heat exchange medium in the upper chamber 11 on the liquid in the lower chamber is greatly weakened, thereby ensuring the thermal insulation performance of the thermos cup to the greatest extent; in addition, the user can heat up or cool down the liquid in the lower chamber by changing the type of heat exchange medium located in the upper chamber 11. When the liquid temperature in the lower chamber is too high and needs to be cooled, the user can add a cooling medium in the upper chamber 11 to achieve a cooling effect. When the liquid temperature in the lower chamber is too low and needs to be heated, the user can add a heating medium in the upper chamber 11 to achieve a heating effect, which meets the diversified usage needs of users and increases the user experience.

[0051] Specifically, if the lower chamber contains high-temperature hot liquid and the user needs to cool it down before drinking, ice water or the like can be added to the upper chamber 11 as a cooling medium to achieve cooling for drinking; if the temperature of the liquid contained in the lower chamber is lower than the palatable temperature that the user wants to drink, hot water or the like can be added to the upper chamber 11 as a heating medium to achieve heating for drinking.

[0052] In one embodiment, the upper cup body 1 and the lower cup body 2 are directly connected, and the partition 3 is built into the upper cup body 1 or the lower cup body 2. For example, one of the upper cup body 1 and the lower cup body 2 is provided with an internal thread, and the other is provided with an external thread, and the two are detachably connected through the internal thread and the external thread, and further, one of the two is provided with a sealing ring to prevent liquid from leaking from the connection position between the two.

[0053] As a preferred implementation of the present application, Figure 1 , Figure 3As shown, the thermos cup further includes a connector 5, the upper cup body 1 and the lower cup body 2 are detachably connected to the connector 5, and the partition 3 is built in the connector 5. The connector 5 is provided to realize the detachable connection between the upper cup body 1 and the lower cup body 2 and the connector 5, so that the user can disassemble the upper cup body 1 and the lower cup body 2 to inject liquid into the lower cup body 2 or heat exchange medium into the upper cup body 1, and the user can disassemble the upper cup body 1 and the lower cup body 2 to clean them separately, thereby reducing the risk of bacteria and impurities growing at the connection between the two and improving the user's convenience; in addition, the connector 5 also provides an installation space for the partition 3, while avoiding the partition 3 from being exposed to the user's field of vision, so that the appearance of the thermos cup has a strong integrity and is pleasing to the user.

[0054] This embodiment does not limit the structural form of the separator 3, and it can adopt any one of the following embodiments:

[0055] Embodiment 1: Figure 3 As shown, a temperature-insulating chamber 31 is provided in the partition 3. Since the efficiency of heat propagation in the temperature-insulating chamber 31 is greatly reduced, the temperature exchange rate between the upper chamber 11 and the lower chamber is greatly reduced by providing the temperature-insulating chamber 31, which helps to improve the heat preservation effect of the thermos cup. Preferably, the temperature-insulating chamber 31 can be provided as a vacuum temperature-insulating chamber 31, which further reduces the temperature propagation rate in the temperature-insulating chamber 31.

[0056] Embodiment 2: A temperature insulation layer is provided on the outer surface of the partition 3 .

[0057] Embodiment 3: A temperature-insulating cavity is provided inside the partition 3 , and a temperature-insulating layer is provided on the outer surface of the partition 3 .

[0058] Embodiment 4: The separator is a structure made of a poor thermal conductor.

[0059] As a preferred embodiment of this implementation, Figure 3 , Figure 5 As shown, the connector 5 is further provided with a first seal 6, and the partition 3 is sealed against the first seal 6 in the circumferential direction; the upper cup body 1 and the lower cup body 2 are sealed against the first seal 6 in the up-down direction. By providing the first seal 6 and sealing the partition 3 against the first seal 6 in the circumferential direction, the circumferential diffusion of heat transferred from the upper cup body 1 to the partition 3 is reduced, thereby reducing the impact on the temperature of the liquid in the lower chamber; the upper cup body 1 and the lower cup body 2 are sealed against the first seal 6 in the up-down direction, respectively, reducing the risk of liquid in the upper and lower chambers leaking through the joint between the upper and lower cup bodies 2 and the connector 5, which helps to improve the airtightness of the thermos cup.

[0060] As a preferred example under this embodiment, Figure 3 , Figure 5 As shown, the connector 5 is provided with a positioning ring 51 extending inwards, and the positioning ring 51 extends along the radial direction of the first seal 6 and is inserted into the first seal 6, and the partition 3 is embedded in the first seal 6; the downward projection of the lower edge of the upper cup body 1 is located within the projection range of the positioning ring 51 in the horizontal direction. By providing the positioning ring 51 and extending and inserting the first seal 6 in the radial direction of the first seal 6, the positioning ring 51 and the first seal 6 jointly bear the gravity of the heat exchange medium in the upper chamber 11, reducing the bearing pressure of the first seal 6, thereby reducing the risk of the partition 3 shifting and falling off due to the deformation of the first seal 6. The downward projection of the lower edge of the upper cup body 1 is located within the projection range of the positioning ring 51 in the horizontal direction, further increasing the bearing area of ​​the positioning ring 51, and further reducing the bearing pressure of the positioning ring 51 and the first seal 6.

[0061] This embodiment does not limit the connection method between the upper cup body 1 and the connecting member 5 and between the lower cup body 2 and the connecting member 5, and any one of the following embodiments may be adopted:

[0062] Embodiment 1: The upper cup body 1 and the connecting member 5 are connected by a snap-fit ​​connection; and / or, the lower cup body 2 and the connecting member 5 are connected by a snap-fit ​​connection.

[0063] Embodiment 2: The connector 5 is provided with a first internal thread section and a second internal thread section, the upper cup body 1 is provided with a first external thread section threadedly connected to the first internal thread section, and the lower cup body 2 is provided with a second external thread section threadedly connected to the second internal thread section. The upper cup body 1 and the lower cup body 2 are respectively connected to the connector 5 by threaded connection, which makes the disassembly and assembly of the upper cup body 1 and the lower cup body 2 more convenient. The user can quickly disassemble and install the upper cup body 1 and the lower cup body 2 by screwing, thereby realizing rapid water filling, replacement of heat exchange medium, cleaning and other operations, which improves the user's experience. Compared with the snap-on connection of embodiment 1, the threaded connection method makes the connection between the upper cup body 1 and the lower cup body 2 and the connector 5 tighter, thereby improving the airtightness of the thermos cup.

[0064] This embodiment does not limit the structural form of the upper cup body 1 and the lower cup body 2, which can be any of the following examples:

[0065] Example 1: The upper cup body 1 is provided with an upper stop step 12, and the upper stop step 12 abuts against the top of the connecting member 5 to limit the feed amount of the upper cup body 1 during the screwing process.

[0066] Example 2: The lower cup body 2 is provided with a lower stop step 21, and the lower stop step 21 abuts against the bottom of the connecting member 5 to limit the feed amount of the lower cup body 2 during the screwing process.

[0067] Example 3: Figure 3 , Figure 4 , Figure 6 As shown, the upper cup body 1 is provided with an upper stop step 12, and the upper stop step 12 abuts against the top of the connecting member 5 to limit the feed amount of the upper cup body 1 during the screwing process; the lower cup body 2 is provided with a lower stop step 21, and the lower stop step 21 abuts against the bottom of the connecting member 5 to limit the feed amount of the lower cup body 2 during the screwing process. By respectively providing an upper stop step 12 and a lower stop step 21 on the upper cup body 1 and the lower cup body 2, when the lower cup body 2 and the upper cup body 1 are screwed into place, the upper stop step 12 and the lower stop step 21 will prevent the upper cup body 1 and the lower cup body 2 from being screwed further, thereby avoiding deformation of the upper cup body 1, the lower cup body 2 and the connecting member 5 caused by excessive screwing; in addition, when the user screws until the upper stop step 12 and the top of the connecting member 5 are butted against each other or the lower stop step 21 and the bottom of the connecting member 5 are butted against each other, there will be an obvious sense of being in place, prompting the user that the upper cup body 1 or the lower cup body 2 has been screwed into place, so that the user can know the screwing status of the upper cup body 1 and the lower cup body 2 without observing the screwing status of the upper cup body 1 and the lower cup body 2, thereby improving the convenience of user use.

[0068] The present application does not limit the structural form of the second straw segment 42, which can be any of the following embodiments:

[0069] Embodiment 1: The portion of the second straw section 42 located in the upper chamber 11 extends vertically in the upper chamber 11. In this embodiment, the movement path of the liquid in the second straw section 42 is the shortest, and the user only needs a small suction force to suck the liquid in the lower chamber.

[0070] Implementation method 2: Figure 3 As shown, the portion of the second straw section 42 located in the upper chamber 11 extends in a winding manner in the upper chamber 11 to extend the flow path of the liquid in the upper chamber 11. The heat exchange time of the liquid in the upper chamber 11 is extended, and the liquid and the heat exchange medium in the upper chamber 11 are fully heat exchanged, thereby reaching the appropriate temperature required by the user.

[0071] Furthermore, the second suction pipe section 42 is made of a good thermal conductor, thereby improving the heat exchange efficiency. For example, the second suction pipe section 42 is a stainless steel pipe.

[0072] As a preferred implementation of the present application, Figure 3As shown, the thermos cup further includes a second sealing member 7 disposed at the communication port, and the first straw section 41 and the second straw section 42 are respectively abutted and sealed against the second sealing member 7. By providing the second sealing member 7, the communication port is sealed, and the heat exchange between the heat exchange medium in the upper chamber 11 and the water in the lower chamber is further reduced, thereby providing a guarantee for the heat preservation performance of the thermos cup; in addition, the second sealing member 7 can also prevent the liquid in the upper chamber 11 and the lower chamber from leaking at the communication port during the process of assembling the upper cup body 1, the lower cup body 2 and the connecting member 5, thereby improving the sealing performance of the thermos cup.

[0073] As a preferred implementation of the present application, Figure 3 As shown, the thermos cup also includes a third seal 8 provided at the drinking port, and the second straw section 42 is abutted and sealed against the third seal 8. Specifically, the method of filling the thermos cup with liquid and adding the heat exchange medium is to first remove the upper cup body 1 together with the connector 5, and then pour the liquid into the lower chamber, invert the upper cup body 1 together with the connector 5, and then remove the connector 5, and then pour the heat exchange medium into the upper chamber 11. When pouring the heat exchange medium into the upper chamber 11, the side of the upper cup body 1 with the drinking port serves as the bottom of the upper cup body 1 at this time. By providing the third seal 8, the risk of the heat exchange medium leaking out from the drinking port can be effectively reduced, thereby improving the user experience.

[0074] In some optional embodiments, the straw 4 is detachably mounted on the drinking port and the communicating port, and the thermos cup further comprises a sealing plug that is removably placed at the drinking port and the communicating port.

[0075] In one embodiment, the straw 4 is movably provided in the second sealing member 7 and the third sealing member 8, so that the straw 4 can be taken out from the second sealing member 7 and the third sealing member 8. The thermos cup can also be provided with sealing plugs respectively adapted to the second sealing member 7 and the third sealing member 8. When the straw 4 is taken out, the sealing plugs can directly block the through hole on the second sealing member 7 through which the straw 4 passes, and block the through hole on the third sealing member 8 through which the straw 4 passes, so that the thermos cup is converted into a conventional thermos cup with two chambers, so that the thermos cup can be used in a more diversified manner to meet various needs.

[0076] In another embodiment, the straw 4, the third sealing member 8 provided at the drinking port, and the second sealing member 7 provided at the communication port can all be removed. Different from the above embodiment, in this embodiment, one sealing plug is adapted to the drinking port so that when the straw 4 and the third sealing member 8 are removed, the drinking port is blocked by the sealing plug, and the other sealing plug is adapted to the communication port so that when the straw 4 and the second sealing member 7 are removed, the communication port is blocked by the sealing plug, thereby converting the thermos cup into a conventional thermos cup with two chambers, making the use of the thermos cup more diversified.

[0077] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0078] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0079] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
