Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to a thermos cup that can reduce the formation of high-temperature water droplets on the bottle cap. Background Technology

[0002] A thermos flask is generally a water-filled container made of ceramic or stainless steel with a vacuum layer. It has a lid that seals tightly, and the vacuum insulation layer slows down heat dissipation from the liquid inside, thus keeping it warm. A good thermos flask has a smooth, odorless exterior, and when filled with boiling water, it doesn't feel hot to the touch. The interior is usually made of stainless steel, with a vacuum chamber between the inner liner and the outer shell. It's crafted using advanced vacuum technology, resulting in an elegant design, seamless inner liner, and excellent sealing performance, providing good heat retention. It can hold ice cubes or hot drinks. Meanwhile, innovative functions and detailed design make new thermos flasks more sophisticated and practical.

[0003] Currently, insulated water bottles are increasingly used and carried by many people, allowing them to enjoy warm water anytime during their travels. However, existing insulated water bottles still have some drawbacks. For example, when hot water is poured into an insulated water bottle, the water continuously evaporates, forming steam. Due to the good seal of the insulated water bottle, this steam accumulates inside. When the lid is opened, the hot steam encounters the relatively cool lid and quickly condenses into small water droplets. These droplets usually carry a high temperature, and because users are often focused on the bottle itself or the beverage they are about to drink when opening the lid, they easily overlook the potential danger posed by these hot water droplets, leading to unintentional contact and burns.

[0004] Therefore, in order to avoid the existing security risks, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermos cup that can reduce the formation of high-temperature water droplets on the bottle cap, comprising an outer shell, an inner liner provided inside the outer shell, a vacuum chamber between the inner liner and the outer shell, one end of the inner liner protruding outside the outer shell and forming a bottle mouth, and a matching bottle cap provided on the bottle mouth.

[0007] An air baffle is provided inside the inner liner. The edge of the air baffle is in close contact with the inner wall of the inner liner. A water outlet groove is provided on the edge of the air baffle. A plug corresponding to the water outlet groove is provided on the bottle cap. When the bottle cap is tightened on the bottle mouth, the plug blocks the water outlet groove.

[0008] As a further embodiment of this utility model: the air baffle is an arc shape that bulges towards the bottle mouth.

[0009] As a further embodiment of this utility model: the bottle cap includes an inner plug and a screw cap that wraps around the inner plug and the bottle mouth;

[0010] The inner plug is located inside the bottle neck, and the plug piece is connected to the inner plug.

[0011] The screw cap is threaded to the outer wall of the bottle mouth.

[0012] The inner plug and the screw cap are rotatably connected.

[0013] As a further embodiment of this utility model: a limiting guide groove is provided on the inner wall of the inner liner, and the outer side of the plug has a limiting protrusion that matches the limiting guide groove.

[0014] As a further embodiment of this utility model: the edge of the air baffle is formed with a connecting piece, and a fixing ring is connected to one side of the connecting piece, and the fixing ring is detachably fixed to the bottle mouth.

[0015] As a further embodiment of this utility model: the fixing ring is provided with a plurality of deformable elastic sheets, which form an elastic pressure against the inner wall of the bottle mouth.

[0016] As a further embodiment of this utility model: multiple water outlet tanks and connecting pieces are provided;

[0017] The multiple water outlets and connecting plates are distributed in a circular array, and the multiple water outlets and connecting plates are arranged in an alternating manner.

[0018] As a further embodiment of this utility model: the inner wall of the bottle mouth is also provided with a positioning notch, and the fixing ring is provided with a positioning protrusion corresponding to the positioning notch.

[0019] As a further embodiment of this utility model: a sealing sleeve is fitted onto the end of the plug inserted into the water outlet groove.

[0020] As a further embodiment of this utility model: a through hole is provided at the center of the screw cap component, a bolt is provided on the outside of the screw cap component, a screw hole is provided at the center of the inner plug block, one end of the bolt passes through the through hole and is screwed into the screw hole, and the screw cap component can rotate with the through hole as the axis.

[0021] Compared with existing technologies, the beneficial effects of this technical solution are as follows: When a user fills the thermos with hot water and tightens the cap, the steam generated by the hot water inside the inner liner is blocked by the baffle plate, preventing steam from entering the bottle mouth area. At the same time, when the cap is tightened, the plug connected to the inside of the cap blocks the edge of the baffle plate, allowing the hot water to flow out of the reserved water outlet. When the cap is opened, the plug moves away from the water outlet along with the cap, allowing the user to pour the hot water from the inner liner for drinking. By blocking the steam through the baffle plate, the accumulation of steam at the bottle mouth and its contact with the cap are reduced when the user opens the cap, thereby reducing the formation of high-temperature water droplets on the cap and thus reducing the possibility of the user coming into contact with high-temperature water droplets, achieving safe use and reducing the occurrence of scalding accidents.

[0032] 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.

[0033] Please see Figure 1-6 A thermos cup that can reduce the formation of hot water droplets on the bottle cap includes an outer shell 1, an inner liner 2 inside the outer shell 1, a vacuum chamber between the inner liner 2 and the outer shell 1, one end of the inner liner 2 protruding outside the outer shell 1 and forming a bottle mouth 3, and a matching bottle cap 4 on the bottle mouth 3.

[0034] An air baffle 5 is provided inside the inner liner 2. The edge of the air baffle 5 is in close contact with the inner wall of the inner liner 2. A water outlet groove 6 is provided on the edge of the air baffle 5. A plug 7 corresponding to the water outlet groove 6 is provided on the bottle cap 4. When the bottle cap 4 is tightened on the bottle mouth 3, the plug 7 blocks the water outlet groove 6.

[0035] Specifically, when a user fills the thermos with hot water and tightens the cap 4, the steam generated by the hot water inside the inner liner 2 is blocked by the baffle 5, preventing the steam from entering the mouth area 3. At the same time, when the cap 4 is tightened, the plug 7 connected to the inside of the cap 4 blocks the edge of the baffle 5, allowing the hot water to flow out of the reserved water outlet 6. When the cap 4 is opened, the plug 7 moves away from the water outlet 6 along with the cap 4, allowing the user to pour the hot water from the inner liner 2 for drinking. By blocking the steam with the baffle 5, the accumulation of steam at the mouth area 3 and its contact with the cap 4 are reduced when the user opens the cap 4, thereby reducing the formation of high-temperature water droplets on the cap 4 and thus reducing the possibility of the user coming into contact with high-temperature water droplets, achieving safe use and reducing the occurrence of scalding accidents.

[0036] During the opening of the bottle cap 4, as the blocking plate 7 is removed, some of the water vapor blocked by the baffle plate 5 will move through the water outlet 6 to the bottle mouth 3 and come into contact with the bottle cap 4. However, compared with the existing technology, it can still significantly reduce the formation of high-temperature water droplets on the bottle cap 4.

[0037] In some embodiments, the air baffle 5 is an arc shape that protrudes towards the bottle mouth 3.

[0038] Specifically, the baffle plate 5 is designed in an arc shape, so that water vapor is trapped within the arc range of the baffle plate 5. When the bottle cap 4 is opened and the plug 7 is pulled out of the water tank 6, this design can reduce the amount of water vapor overflowing from the water tank 6, thereby further reducing the formation of high-temperature water droplets on the bottle cap 4.

[0039] In some embodiments, the bottle cap 4 includes an inner plug 8 and a screw cap 9 that encloses the inner plug 8 and the bottle mouth 3;

[0040] The inner plug 8 is located inside the bottle mouth 3, and the plug 7 is connected to the inner plug 8.

[0041] The capping component 9 is threadedly connected to the outer wall of the bottle mouth 3;

[0042] The inner plug 8 and the screw cap 9 are rotatably connected.

[0043] Specifically, during the process of tightening the bottle cap 4 onto the bottle mouth 3, the inner plug 8 first enters the bottle mouth 3, and then the plug 7 connected to the inner plug 8 is inserted into the water outlet 6. This causes the movement direction of the inner plug 8 and the plug 7 to be restricted by the guide of the water outlet 6. The inner plug 8 is rotatably connected to the cap screwing part 9. When the cap screwing part 9 is rotated, as the cap screwing part 9 gradually engages with the threads on the outer wall of the bottle mouth 3, the cap screwing part 9 will drive the inner plug 8 to move toward the bottle mouth 3. When the cap screwing part 9 is fully tightened and keeps sealed with the outer wall of the bottle mouth 3, the plug 7 on the inner plug 8 has also completely blocked the water outlet 6.

[0044] In another embodiment, a limiting guide groove 10 is formed on the inner wall of the inner liner 2, and the outer side of the plug 7 has a limiting protrusion 11 that matches the limiting guide groove 10.

[0045] Specifically, through the setting of the limiting guide groove 10 and the limiting protrusion 11, during the process of tightening and fixing the bottle cap 4 to the bottle mouth 3, the limiting protrusion 11 on the plug 7 will engage with the limiting guide groove 10, thereby forming a guiding restriction on the movement direction of the inner plug 8 and the plug, and then the plug 7 is inserted into the water outlet 6.

[0046] This allows the thickness of the baffle plate 5 to be designed to be thinner, and the water outlet groove 6 does not need to be set to a deeper depth to meet the guide of the plug plate 7, thereby reducing material consumption and lowering costs. That is, the limiting protrusion 11 of the plug plate 7 will first fit into the limiting guide groove 10, and as the inner plug block 8 gradually moves inward, the end of the plug plate 7 will be inserted into the water outlet groove 6.

[0047] In some embodiments, the edge of the air baffle 5 is formed with a connecting piece 12, and a fixing ring 13 is connected to one side of the connecting piece 12. The fixing ring 13 is detachably fixed to the bottle mouth 3.

[0048] Specifically, the air baffle 5 is connected to the fixing ring 13 inside the bottle mouth 3 through the connecting piece 12. The fixing ring 13 is detachably fixed in the bottle mouth 3, so that the air baffle 5 can be removed from the inner liner 2 by removing the fixing ring 13. This not only makes it convenient to clean the air baffle 5 daily, but also makes it convenient to clean the inside of the inner liner 2 or pour out the soaked substances inside, such as tea leaves.

[0049] In some embodiments, the retaining ring 13 is provided with a plurality of deformable elastic sheets 14, which form an elastic resistance force to the inner wall of the bottle mouth 3.

[0050] Specifically, when the baffle plate 5 is placed inside the inner liner 2, the fixing ring 13 is located in the bottle mouth 3. At the same time, the elastic plate 14 provided on the fixing ring 13 will apply elastic pressure to the inner wall of the bottle mouth 3, thereby fixing the fixing ring 13 in the position of the bottle mouth 3. When removing it, the user only needs to apply a force greater than the friction between the elastic plate 14 and the inner wall of the bottle mouth 3 to remove the fixing ring 13 and the baffle plate 5.

[0051] In some embodiments, both the water outlet 6 and the connecting piece 12 are provided with multiple portions;

[0052] Among them, multiple water outlet tanks 6 and connecting pieces 12 are distributed in a circular array, and the multiple water outlet tanks 6 and connecting pieces 12 are arranged in an alternating manner.

[0053] Specifically, the design of multiple water outlets 6 allows hot water to flow out from multiple outlets when the user opens the bottle cap 4 to pour out the water. This avoids the situation where the water outlets 6 are positioned at the top, causing the hot water to be blocked by the air baffle 5 and gradually accumulate before spraying out directly from the top, resulting in hot water splashing and scalding the user. The design of multiple connecting pieces 12 not only ensures a stable connection between the air baffle 5 and the fixing ring 13, but also, by interlacing with the multiple water outlets 6, ensures that the water outlets 6 are evenly distributed, making it more convenient for the user.

[0054] Preferably, when the baffle plate 5 is placed into the inner liner, the position of the water outlet groove 6 should correspond to the position of the limiting guide groove 10, so that the plug 7 can be aligned with the water outlet groove 6 and inserted. More preferably, the inner wall of the bottle mouth 3 is also provided with a positioning notch 15, and the fixing ring 13 is provided with a positioning protrusion 16 corresponding to the positioning notch 15. When the baffle plate 5 is placed in, the positioning protrusion 16 on the fixing ring 13 is engaged with the positioning notch 15 to ensure that the position of the water outlet groove 6 corresponds to the position of the limiting guide groove 10.

[0055] In some embodiments, a sealing sleeve 17 is fitted onto the end of the plug 7 inserted into the water outlet 6.

[0056] Specifically, when the plug 7 is inserted into the water outlet groove 6, the sealing sleeve 17 fitted at the end of the plug 7 can improve the sealing between the plug 7 and the water outlet groove 6, which can not only prevent water vapor from leaking out, but also improve the heat preservation effect to a certain extent.

[0057] The sealing sleeve 17 can be made of silicone rubber.

[0058] In some embodiments, a sealing ring (not shown in the figure) should also be provided between the screw cap 9 and the outer wall of the bottle mouth 3. When the screw cap 9 is gradually tightened, the screw cap 9 gradually squeezes the sealing ring, thereby keeping the screw cap 9 and the bottle mouth 3 sealed and ensuring that the heat preservation effect is not affected.

[0059] In some embodiments, a through hole 18 is provided at the center of the screw cap 9, a bolt 19 is provided on the outside of the screw cap 9, and a screw hole 20 is provided at the center of the inner plug 8. One end of the bolt 19 passes through the through hole 18 and is screwed into the screw hole 20, and the screw cap 9 can rotate with the through hole 18 as the axis.

[0060] Specifically, the bolt 19 passes through the through hole 18 on the capping piece 9 and is screwed into the threaded hole 20 on the inner plug 8. The bolt 19 is only threaded at the end and has a smooth surface in the area of ​​the through hole 18. This allows the capping piece 9 to rotate on the bolt 19, thereby forming a rotatable connection between the inner plug 8 and the capping piece 9.

[0061] In some embodiments, two washers 21 are fitted onto the bolt 19, and the two washers 21 are sandwiched between the openings on both sides of the through hole 18.

[0062] Specifically, the clamping force of the two gaskets 21 on the capping part 9 can increase the rotational resistance of the capping part 9, so as to prevent the capping part 9 from rotating on its own, which would make it difficult for the plug 7 to align with the water outlet 6 when the inner plug 8 is inserted.

[0063] In some embodiments, the inner plug 8 is provided with a sealing kit 22, and the sealing kit 22 is sleeved with the outlet portion of the bottle mouth 3.

[0064] Specifically, the sealing kit 22 of the inner plug 8 is used to keep the inner plug 8 and the bottle mouth 3 sealed, thereby further improving the overall sealing performance and enhancing the heat preservation effect.

[0065] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
