Description

Technical Field

[0001] This application relates to the field of household goods, and in particular to a thermos cup. Background Technology

[0002] A thermos consists of a body and a lid, which are usually connected by threads. When a user needs to drink water from the thermos, they need to rotate the lid to separate it from the body. After drinking, the lid needs to be placed back on the body and then screwed on to secure it. This process is complicated and cumbersome. In addition, during the process of resetting the lid, it is easy for the lid to not be tightened properly, which can lead to leakage.

[0003] Therefore, a new type of insulated cup has emerged on the market, comprising a threaded cup body and a lid. The lid has a drinking spout, and a cap is hinged to the lid to seal the drinking spout. A torsion spring is installed on the hinge shaft of the cap, and a locking foot is installed at the end away from the hinge shaft. The lid has a slot for the locking foot to engage and a spring-loaded control button. When the cap is rotated to close the drinking spout, the torsion spring is in a torsional tension state, and the locking foot engages in the slot. When the user needs drinking water, they press the spring-loaded control button inward, thereby causing the locking foot to disengage from the slot. Under the elastic force of the torsion spring, the cap springs open, and the drinking spout opens, allowing the user to drink water through the spout.

[0004] The aforementioned new type of thermos cup solves the shortcomings of the traditional thermos cup's complicated and cumbersome switch, making it easy to open; simply pressing the elastic control button opens the drinking spout. However, in actual use, users sometimes need to carry the thermos cup out, requiring it to be placed in a bag or case. When the thermos cup is placed in the bag or case, various items inside are prone to bumping or knocking, which can cause the elastic control button to be accidentally pressed, resulting in the drinking spout being opened and water leaking out, leading to a poor user experience. Summary of the Invention

[0005] To address the problems existing in the above-mentioned technologies, this application provides a thermos cup.

[0006] The insulated cup provided in this application adopts the following technical solution:

[0007] A thermos cup includes a detachably connected cup body and a cup lid. The cup lid has a drinking spout, and a sealing seat for closing the drinking spout is hinged to the cup lid. A locking tongue is slidably mounted on the sealing seat, and a first push spring is provided on the sealing seat to abut against the locking tongue. The cup lid has a locking groove for the locking tongue to engage. A rotating column is rotatably connected to the locking tongue, and a protrusion is provided on the rotating column. The protrusion includes a movable arc surface and a locking arc surface. The diameter of the locking arc surface is larger than that of the movable arc surface. A limiting seat is provided on the sealing seat, and the locking arc surface can rotate to abut against the limiting seat to restrict the sliding of the locking tongue.

[0008] By adopting the above technical solution, when the user does not need drinking water, the sealing seat closes the drinking spout, the locking tongue engages in the locking groove, and the first push spring abuts against the locking tongue and is in a compressed state, thereby preventing the locking tongue from separating from the locking groove, thus achieving the first layer of locking; at this time, the movable arc surface mates with the limiting seat, and there is a certain distance between the movable arc surface and the limiting seat. Then, the rotating column is driven to rotate, the rotation of the rotating column drives the cam to rotate, and the rotation of the cam drives the locking arc surface to rotate. When the locking arc surface rotates to abut against the limiting seat, with the cooperation of the first push spring, the locking tongue cannot disengage from the locking groove, thus achieving the second layer of locking; the coordination of each component in the above process The device features a dual-locking mechanism for the thermos. When the user doesn't need to carry the thermos and wants to seal the drinking spout after drinking, the first layer of locking closes the spout. To drink, the user simply slides the rotating pin, which causes the locking tongue to slide out of the locking groove, allowing the sealing seat to rotate and the drinking spout to be exposed. This is simple and convenient. When the user needs to carry the thermos and place it in a bag or case, the second layer of locking closes the drinking spout, preventing accidental opening and leakage of water from the thermos, thus providing a better user experience.

[0009] Optionally, the sealing seat is provided with a hemispherical block made of anti-slip material, the hemispherical block is provided with a sliding groove, the cup body is provided with a hemispherical groove that matches the hemispherical block, a fixing block is provided in the hemispherical groove, the fixing block is located in the sliding groove and slides in cooperation with the sliding groove.

[0010] By adopting the above technical solution, when the sealing seat closes the drinking spout, the hemispherical block is completely located in the hemispherical groove. When the user needs drinking water, rotating the rotating column causes the movable arc surface to align with the limiting block. Then, the rotating column is slid, and the sliding of the rotating column causes the locking tongue to slide, thereby driving the locking tongue to separate from the locking groove. Then, the sealing seat is rotated, and at this time, the hemispherical block rotates in the hemispherical groove and slides in the sliding groove. Since the hemispherical block is made of anti-slip material, the sealing seat will not suddenly pop open. When the thermos cup is filled with hot water, the hot water and steam will not spray out due to the sealing seat opening too quickly, thereby further improving the practicality of the thermos cup.

[0011] Optionally, a limiting ring is provided below the drinking spout, a straw is inserted through the drinking spout, the bottom end of the straw is connected to an elastic hose, the elastic hose is located inside the cup body, and the total length of the straw and the elastic hose is greater than the height of the cup body.

[0012] By adopting the above technical solution, the straw design further facilitates the use of the thermos. Users can drink water from the thermos simply by using the straw. Since the total length of the straw and the flexible hose is greater than the height of the cup, when the sealing seat is pressed down to close the drinking spout, the flexible hose bends, and the upper end of the straw is pressed into the cup by the sealing seat, with the upper end of the straw abutting against the sealing seat. Because a limit ring is set below the drinking spout, the upper end of the straw is always confined within the limit ring. When the sealing seat is opened upwards to open the drinking spout, the pressure on the upper end of the straw is removed, and the flexible hose springs back, popping the upper end of the straw out of the drinking spout for the user to drink from.

[0013] Optionally, the cup lid is provided with two handle seats, and the same handle is rotatably connected to the two handle seats; the handle seats are provided with multiple hemispherical grooves along the circumference of the handle rotation axis, and the handle is provided with a hemispherical protrusion, which can be engaged in any hemispherical groove.

[0014] By adopting the above technical solution, the handle design further facilitates the use of the thermos. When the user needs to carry the thermos, they can rotate the handle, which drives the hemispherical protrusion to rotate. When the hemispherical protrusion engages with the hemispherical groove, the handle is initially fixed. When the user applies force to the handle again, the hemispherical protrusion can move out of the hemispherical groove, thereby improving the stability of the handle. Multiple hemispherical grooves also allow the user to adjust the position of the handle according to actual needs.

[0015] Optionally, a positioning groove is provided on the handle base, and a positioning block is provided on the handle. When the handle is rotated to be perpendicular to the cup lid, the hemispherical protrusion is engaged in the hemispherical groove, and the positioning block is engaged in the positioning groove.

[0016] By adopting the above technical solution, when the handle is rotated to the vertical position, the user can lift the handle and then lift the thermos. At this time, the hemispherical protrusion is engaged in the hemispherical groove, and the positioning block is engaged in the positioning groove, so that the handle is in a stable state and will not shake when the user lifts it.

[0017] Optionally, the locking tongue is provided with an arc-shaped protrusion, the convex plate is provided with a deformation groove, the convex plate is provided with a movable arc groove and a locking arc groove, when the movable arc surface is engaged with the limiting block, the arc-shaped protrusion is engaged in the movable arc groove, and when the locking arc surface is abutted against the limiting block, the arc-shaped protrusion is engaged in the locking arc groove.

[0018] By adopting the above technical solution, during the first layer of locking, the movable arc surface aligns with the limiting block, the bolt engages in the locking groove, and the arc-shaped protrusion engages in the movable arc groove, thereby improving the stability of the bolt in the first layer of locking. At this time, a certain force needs to be applied to make the arc-shaped protrusion disengage from the movable arc groove, and the deformation groove provides the deformation at this time. When the second layer of locking is performed, the locking arc surface abuts against the limiting block, and the arc-shaped protrusion engages in the locking arc groove, thereby similarly improving the stability of the second layer of locking.

[0019] Optionally, the limiting block has a placement groove, a wedge-shaped locking block is slidably placed in the placement groove, a second push spring is provided in the placement groove, one end of the second push spring is fixedly connected to the placement groove, and the other end is fixedly connected to the wedge-shaped locking block, and a locking groove is provided on the locking arc surface for the wedge-shaped locking block to be engaged.

[0020] By adopting the above technical solution, when the locking arc surface rotates to abut against the limiting block, the second push spring pushes the wedge-shaped block to slide into the slot, thereby improving the stability when the locking arc surface abuts against the limiting block, and thus improving the stability of the second layer of locking. At this time, the user needs to apply a certain force to drive the rotating column to rotate, so that the wedge-shaped block separates from the slot and the locking arc surface can rotate.

[0021] Optionally, the cup body includes an insulated cup holder, the insulated cup holder has a water-holding base inside, the water-holding base is provided with a fixing ring, both ends of the fixing ring are provided with threaded sections, one of the threaded sections is threadedly engaged with the insulated cup holder, and the other threaded section is threadedly engaged with the cup lid.

[0022] By adopting the above technical solution, the water-holding base is located inside the thermos cup holder. The water-holding base is used to hold drinking water, and the thermos cup holder keeps the water in the water-holding base warm. When the temperature of the drinking water in the thermos cup is high and the user needs to speed up the cooling of the drinking water in the water-holding base, the fixing ring can be rotated to contact the fixing of the water-holding base and separate the water-holding base from the thermos cup holder, thereby speeding up the cooling of the drinking water in the water-holding base.

[0023] Optionally, a gap layer is formed between the water-holding base and the thermos cup holder, and a hand-operated pump is provided on the thermos cup holder, with the air intake of the hand-operated pump communicating with the gap layer.

[0024] By adopting the above technical solution, the gap layer facilitates the separation of the water-holding base from the thermos cup base. However, the gap layer can easily lead to heat loss. Therefore, when the water-holding base is inside the thermos cup base, a hand-operated pump is used to vacuum the gap layer, thereby forming a vacuum insulation layer. The gap layer wraps around the entire water-holding base, thus isolating the heat transfer of hot water, preventing heat loss, and improving the insulation effect.

[0025] Optionally, the air extraction port of the hand-operated pump is connected to the gap layer through an air extraction pipe, a vacuum insulation layer is provided inside the thermos cup holder, and a branch pipe connected to the vacuum insulation layer is opened on the air extraction pipe.

[0026] By adopting the above technical solution, the vacuum insulation layer inside the thermos cup holder further improves the overall heat preservation effect of the thermos cup. When the gap layer is evacuated by the hand-controlled pump, the hand-controlled pump also evacuates the vacuum insulation layer, thereby ensuring the heat preservation effect and improving the service life of the thermos cup.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. It can achieve double locking of the thermos. When the user does not need to carry the thermos and needs to close the drinking spout after drinking, the first layer of locking can close the drinking spout. When the user needs to drink, simply slide the rotating pin, which will cause the locking tongue to slide out of the locking groove, and then rotate the sealing seat to expose the drinking spout, allowing the user to drink water. The operation is simple and convenient. When the user needs to carry the thermos and place it in a bag or case, the second layer of locking can close the drinking spout, thus preventing the drinking spout from being accidentally opened and preventing water from leaking out of the thermos, providing a better user experience.

[0029] 2. Because the hemispherical block is made of non-slip material, the sealing base will not suddenly pop open. When the thermos is filled with hot water, the hot water and steam will not spray out due to the sealing base opening too quickly, thus further improving the practicality of the thermos.

[0030] 3. When the handle is rotated to the vertical position, the user can lift the handle and then lift the thermos. At this time, the hemispherical protrusion is engaged in the hemispherical groove, and the positioning block is engaged in the positioning slot, so that the handle is in a stable state and will not wobble when the user lifts it.

[0044] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0045] Example 1

[0046] Example 1 discloses a thermos cup. (Refer to...) Figure 1 and Figure 2The thermos includes a threaded cup body 1 and a lid 2. The lid 2 has a drinking spout 3, and a sealing seat 4 for sealing the drinking spout 3 is hinged to the lid 2. A locking tongue 5 slides on the sealing seat 4. (Refer to...) Figure 3 The sealing seat 4 is provided with a first push spring 6 that abuts against the locking tongue 5, and the cup lid 2 is provided with a locking groove 7 for the locking tongue 5 to be engaged; see reference Figure 4 and Figure 5 A rotating pin 8 is rotatably connected to the latch 5. The upper end of the rotating pin 8 is above the sealing seat 4, and the lower end is inserted into the sealing seat 4 and passes through the latch 5 before being connected to a protrusion 9. The hole on the latch 5 for the insertion of the rotating pin 8 is smaller than the protrusion 9 to ensure that the rotating pin 8 will not come out of the latch 5. The protrusion 9 includes a concentric movable arc surface 901 and a locking arc surface 902. The diameter of the locking arc surface 902 is larger than that of the movable arc surface 901. A limit seat 30 is provided on the sealing seat 4. The limit seat 30 is located behind the protrusion 9 below the latch 5. The distance between the center of the rotating pin 8 and the limit seat 30 is equal to the diameter of the locking arc surface 902. The locking arc surface 902 can rotate to abut against the limit seat 30 to restrict the sliding of the latch 5.

[0047] Reference Figure 5 and Figure 6 The locking tongue 5 has an integrally formed arc-shaped protrusion 23. The convex plate 9 has a deformation groove 903, a movable arc groove 904, and a locking arc groove 905. When the movable arc surface 901 mates with the limiting seat 30, the arc-shaped protrusion 23 is engaged in the movable arc groove 904. When the locking arc surface 902 abuts with the limiting seat 30, the arc-shaped protrusion 23 is engaged in the locking arc groove 905. During the first layer of locking, the movable arc surface 901 mates with the limiting seat 30, the locking tongue 5 is engaged in the locking groove 7, and the arc-shaped protrusion 23 is engaged in the movable arc groove 904, thereby improving the stability of the locking tongue 5 in the first layer of locking. At this time, a certain force needs to be applied to make the arc-shaped protrusion 23 disengage from the movable arc groove 904. The deformation groove 903 provides the deformation at this time. When the second layer of locking is performed, the locking arc surface 902 abuts with the limiting seat 30, and the arc-shaped protrusion 23 is engaged in the locking arc groove 905.

[0048] Reference Figure 4 and Figure 5 A spring seat is fixed on the closed seat 4. A spring groove is opened on the opposite side of the locking tongue 5 and the spring seat. A spring post is fixed in the spring groove. One end of the first push spring 6 is sleeved on the spring post on the locking tongue 5 and fixedly connected to the locking tongue 5. The other end is sleeved on the spring post on the spring seat and fixedly connected to the spring seat. A limiting protrusion 34 is also fixed on the closed seat 4 to limit the sliding direction of the locking tongue 5. The locking tongue 5 contacts the limiting protrusion 34 during the sliding process, thereby preventing the locking tongue 5 from deviating during the movement.

[0049] Reference Figure 2 and Figure 7A knob 33 for easy operation is fixed on the rotating column 8. A hemispherical block 10 made of anti-slip material is provided on the sealing seat 4. A sliding groove 11 is opened on the hemispherical block 10. A hemispherical groove 13 that matches the hemispherical block 10 is opened on the cup body 1. A fixing block 12 is provided in the hemispherical groove 13. The fixing block 12 is located in the sliding groove 11 and slides in cooperation with the sliding groove 11. When the sealing seat 4 closes the drinking spout 3, the hemispherical block 10 is completely located in the hemispherical groove 13. When the user needs drinking water, the rotating column 8 is rotated so that the movable arc surface 901 is connected with the limiting block. Then the rotating column 8 is slid. The sliding of the rotating column 8 drives the locking tongue 5 to slide, thereby driving the locking tongue 5 to separate from the locking groove 7. Then the sealing seat 4 is rotated. At this time, the hemispherical block 10 rotates in the hemispherical groove 13 and slides in the sliding groove 11. Since the hemispherical block 10 is made of anti-slip material, the sealing seat 4 will not suddenly pop open.

[0050] Reference Figure 8 and Figure 9 The cup lid 2 has two opposing handle seats 17 fixed on it. The two handle seats 17 are located on both sides of the sealing seat 4. Each of the two sealing seats 4 has a cylindrical mating groove 32 on its opposite side. The two handle seats 17 are rotatably connected to the same handle 18. Both ends of the handle 18 are fixed with cylindrical protrusions 34, which are located in the corresponding mating grooves 32. Both handle seats 17 have multiple sets of mating grooves 32 along the circumference of the corresponding mating grooves 32. Each set of mating grooves 32 includes two opposing hemispherical grooves 19. The handle 18 has multiple sets of mating grooves 32 along the circumference of the corresponding mating grooves 32. The circumference of the protrusion 34 is fixed with multiple sets of hemispherical protrusions 20. Each set of hemispherical protrusions 20 includes two opposing hemispherical protrusions 20. Each set of hemispherical protrusions 20 can be engaged in any set of hemispherical grooves 19. The handle base 17 is provided with a positioning groove 21. The handle 18 is fixed with a positioning block 22. The positioning block 22 is hemispherical, or its top and bottom are connected by an arc surface. When the handle 18 is rotated to be perpendicular to the cup lid 2, a set of hemispherical protrusions 20 is engaged in the corresponding set of hemispherical grooves 19, and the positioning block 22 is engaged in the positioning groove 21 at the same time.

[0051] The handle 18 further facilitates the use of the thermos. When the user needs to carry the thermos, they can rotate the handle 18, which causes the hemispherical protrusion 20 to rotate. When the hemispherical protrusion 20 is engaged in the hemispherical groove 19, the handle 18 is initially fixed. When the user applies force to the handle 18 again, the hemispherical protrusion 20 can be moved out of the hemispherical groove 19. When the handle 18 is rotated to a vertical position, the user can lift the handle 18 and then lift the thermos. At this time, the hemispherical protrusion 20 is engaged in the hemispherical groove 19, and the positioning block 22 is engaged in the positioning groove 21, so that the handle 18 is in a stable state and will not wobble when the user lifts it.

[0052] In this embodiment of the application, in order to further improve the stability of the handrail, the hemispherical groove 19 and the hemispherical protrusion 20 are configured as a mating group.

[0053] Reference Figure 2 and Figure 3 A limiting ring 14 is fixed below the drinking spout 3. A straw 15 is inserted through the drinking spout 3, and the bottom end of the straw 15 is connected to an elastic hose 16. The top end of the straw 15 is located in the limiting ring 14, and the elastic hose 16 is located inside the cup body 1. The total length of the straw 15 and the elastic hose 16 after connection is greater than the height of the cup body 1. The straw 15 further facilitates the use of the thermos cup by allowing the user to drink water from the thermos cup through the straw 15. Since the total length of the straw 15 and the elastic hose 16 after connection is greater than the height of the cup body 1, the straw 15 is designed to make it easier for the user to use the thermos cup. The user can drink water from the thermos cup through the straw 15. The height of the body 1 causes the flexible hose 16 to bend when the sealing seat 4 presses down to seal the drinking spout 3, and the upper end of the straw 15 is pressed into the cup body 1 by the sealing seat 4, and the upper end of the straw 15 abuts against the sealing seat 4. Since a limit ring 14 is provided below the drinking spout 3, the upper end of the straw 15 is always restricted within the limit ring 14. When the sealing seat 4 opens the drinking spout upward, the pressure on the upper end of the straw 15 is removed, so the flexible hose 16 springs back and pops the upper end of the straw 15 out of the drinking spout.

[0054] The implementation principle of a thermos cup in Embodiment 1 of this application is as follows: When the user does not need drinking water, the sealing seat 4 seals the drinking spout 3, the locking tongue 5 is engaged in the locking groove 7, and the first push spring 6 abuts against the locking tongue 5 and is in a compressed state, thereby preventing the locking tongue 5 from separating from the locking groove 7, thus achieving the first layer of locking; at this time, the movable arc surface 901 is connected to the limiting seat 30, and there is a certain distance between the movable arc surface 901 and the limiting seat 30. Then, the rotating column 8 is driven to rotate, and the rotation of the rotating column 8 drives the convex plate 9 to rotate. The rotation of the convex plate 9 drives the locking arc surface 902 to rotate. When the locking arc surface 902 rotates to abut against the limiting seat 30, with the cooperation of the first push spring 6, the locking tongue 5 cannot disengage from the locking groove 7, thus achieving the second layer of locking; when the rotating column 8 is rotated so that the movable arc surface 901 is opposite to the limiting seat 30, since there is still a distance between the movable arc surface 901 and the limiting seat 30, Therefore, pushing the rotating column 8 backward at this time will cause the rotating column 8 to move the convex plate 9 and the locking tongue 5 backward together, thereby disengaging the locking tongue 5 from the locking groove 7. At this time, the sealing seat 4 can be opened to expose the drinking spout 3. The cooperation of the various components in the above process can achieve double locking of the thermos cup. When the user does not need to carry the thermos cup and needs to close the drinking spout 3 after drinking, the drinking spout 3 can be closed by the first layer of locking. When the user needs to drink, he only needs to slide the rotating column 8. The rotating column 8 drives the locking tongue 5 to slide until it is separated from the locking groove 7, and then the sealing seat 4 can be rotated to expose the drinking spout 3, so that the user can drink water. The operation is simple and convenient. When the user needs to carry the thermos cup and puts the thermos cup in a bag or case, the drinking spout 3 can be closed by the second layer of locking, thereby preventing the drinking spout 3 from being opened by mistake and preventing the water in the thermos cup from leaking out through the drinking spout 3, so as to give the user a good experience.

[0055] Example 2

[0056] The difference between Example 2 and Example 1 is that: (Refer to...) Figure 10 and Figure 11 The limiting seat 30 has a placement groove 24, in which a wedge-shaped locking block 25 slides. A second push spring 26 is provided in the placement groove 24, with one end fixed to the placement groove 24 and the other end fixed to the wedge-shaped locking block 25. A locking groove 27 is provided on the locking arc surface 902 for the wedge-shaped locking block 25 to be engaged. When the locking arc surface 902 rotates to abut against the limiting seat 30, the second push spring 26 pushes the wedge-shaped locking block 25 to slide into the locking groove 27, thereby improving the stability of the locking arc surface 902 when it abuts against the limiting seat 30, and thus improving the stability of the second layer of locking. At this time, the user needs to apply a certain force to drive the rotating column 8 to rotate, so that the wedge-shaped locking block 25 separates from the locking groove 27, and the locking arc surface 902 can rotate.

[0057] Reference Figure 10 and Figure 12The cup body 1 includes an insulated cup holder 101, a water-holding base 102 inside the insulated cup holder 101, a fixing ring 103 on the water-holding base 102, and threaded sections at both ends of the fixing ring 103. One threaded section is threaded to the insulated cup holder 101, and the other threaded section is threaded to the cup lid 2. A gap layer 28 is formed between the water-holding base 102 and the insulated cup holder 101. A hand-operated pump 29 is installed on the insulated cup holder 101. The air extraction port of the hand-operated pump 29 is connected to the gap layer 28 through an air extraction pipe. A vacuum insulation layer 31 is installed inside the insulated cup holder 101. A branch pipe connected to the vacuum insulation layer 31 is opened on the air extraction pipe.

[0058] The implementation principle of Example 2 is as follows: The water-holding base 102 is located inside the thermos cup holder 101. The water-holding base 102 is used to hold drinking water, and the thermos cup holder 101 keeps the water in the water-holding base 102 warm. When the temperature of the drinking water in the thermos cup is high and the user needs to speed up the cooling of the drinking water in the water-holding base 102, the fixing ring 103 can be rotated to contact the fixing of the water-holding base 102, thereby separating the water-holding base 102 from the thermos cup holder 101, which can speed up the cooling of the drinking water in the water-holding base 102; the gap layer 28 facilitates the separation of the water-holding base 102 from the thermos cup holder 101. While the water-holding base 102 is separated from the thermos cup base 101, the gap layer 28 is vacuumed by the hand-operated pump 29. This causes the gap layer 28 to form a vacuum insulation layer 31, which covers the entire water-holding base 102, thus isolating the heat transfer of hot water and preventing heat loss. When the gap layer 28 is vacuumed by the hand-operated pump 29, the hand-operated pump 29 also vacuums the vacuum insulation layer 31, thereby ensuring the insulation effect and improving the service life of the thermos cup.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
