Detailed description of the specific embodiment

[0019] The following will describe the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present disclosure, and are not used to limit the present disclosure.

[0020] In the description of the present disclosure, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation of the present disclosure. For example, referring to Figure 1 , Figure 1 the upper side in the drawing direction of Figure 1The upper side of the drawing direction is the "lower" side, and "inner and outer" refer to the inside and outside of the corresponding structural outline. In addition, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "connected", "linked", "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0022] As Figures 1 to 5 shown, the present disclosure provides a multifunctional thermos cup, including a cup body 10, a cup lid 20, a receiving bladder 30 and a connecting member 40. The internal space of the receiving bladder 30 is set as a receiving cavity 31 for receiving a heat carrier. One end of the receiving bladder 30 is an open end, and the other end of the receiving bladder 30 is a closed end. The cup body 10 has a cavity 11 for receiving the receiving bladder 30. The top of the cavity 11 has a first opening 12. A flow channel 41 is formed on the connecting member 40, and the axis of the flow channel 41 extends along the thickness direction of the connecting member 40. The cup lid 20 is detachably covered on the first end of the connecting member 40. The second end of the connecting member 40 is provided with a connection to the open end of the receiving bladder 30 and is detachably connected to the first opening 12 so that the flow channel 41 can communicate with the receiving cavity 31.

[0023] It should be understood that the heat carrier can be hot water, ice cubes, or warm water.

[0024] Through the above technical solution, since the cup lid 20 is detachably connected to the first end of the connecting member 40, and the second end of the connecting member 40 is provided with the receiving bladder 30, and the inside of the receiving bladder 30 can receive a heat carrier (such as hot water, ice cubes or warm water), therefore, the cup lid 20 can play a role in sealing the receiving bladder 30, thereby preventing the heat carrier from leaking. And, since the cup body 10 is detachably connected to the second end of the connecting member 40, therefore, when ice application or hot compress is needed, the cup body 10 can be detached from the connecting member 40, so that the receiving bladder 30 can be taken out from the cup body 10 for use. At this time, the cup lid 20 is in a state of being connected to the connecting member 40. When it is necessary to provide heat preservation or cold preservation effects for the drink (heat carrier), the cup body 10 can be installed on the connecting member 40 so that the receiving bladder 30 can be placed in the cavity 11 of the cup body 10, thereby isolating the receiving bladder 30 from the outside world, reducing heat exchange, and effectively improving the heat preservation or cold preservation effect.

[0025] As an implementation manner, as Figure 2 andFigure 5 As shown, the accommodating bladder 30 is constructed as a food-grade silicone part, and the cup body 10 is constructed as a double-layer vacuum structure.

[0026] By setting the food-grade silicone part, the food-grade silicone part is a safe and harmless material that will not release harmful substances, ensuring the health of users. Moreover, when the accommodating bladder 30 is used for hot compress or cold compress, the silicone material has a soft and smooth surface, which is very friendly to the skin and can avoid causing irritation or discomfort. The silicone material is relatively lighter than some materials (ceramic material, glass material, stainless steel material). In this way, the weight of the entire thermos cup can be reduced, which is more convenient and less burdensome for users, especially when carrying this thermos cup during outdoor activities, traveling or sports. In addition, the silicone material can quickly transfer heat (or cold) to the part that needs hot compress or cold compress.

[0027] Among them, the double-layer vacuum design can greatly reduce heat conduction, so as to effectively maintain the temperature of the internal drink, and can achieve good effects both for heat preservation and cold preservation. Moreover, due to the existence of the double-layer design, users will not directly feel the temperature of the internal drink when holding it, which can avoid the discomfort caused by overheating or overcooling and can improve the comfort of use.

[0028] As an implementation manner, as Figure 2 and Figure 5 shown, the connecting member 40 includes a connecting cylinder 42 and an annular fitting portion 43 sleeved on the connecting cylinder 42. There is a gap 45 between the annular fitting portion 43 and the connecting cylinder 42. The gap 45 is constructed to be able to insert the open end of the accommodating bladder 30 and connect with the open end of the accommodating bladder 30. A first internal thread 21 is provided inside the cup lid 20. The cup lid 20 is arranged to cooperate with a first external thread 421 on the outer peripheral wall of the connecting cylinder 42 through the first internal thread 21. A second internal thread 13 is provided inside the cup body 10. The cup body 10 is arranged to cooperate with a second external thread 44 on the outer peripheral wall of the annular fitting portion 43 through the second internal thread 13.

[0029] Among them, the method of using thread fitting can achieve quick connection and disassembly, ensure good sealing of each connection point, reduce the risk of water leakage, and improve the stability of the overall structure at the same time.

[0030] As an implementation manner, as Figure 3 shown, the flow channel 41 is formed as a tapered structure, and the radial dimension of the tapered structure gradually decreases along the direction from the cup lid 20 to the cup body 10.

[0031] Among them, in the design of the tapered structure, on the one hand, since the radial dimension of the outlet end (the position for drinking water) is relatively large, more operating space can be provided for the installation of the gear member 50. This enables the following gear member 50 to be more easily installed in the flow channel 41. That is, the larger opening facilitates the insertion and positioning of the gear member 50, ensuring that the gear member 50 can be accurately placed at the predetermined position. On the other hand, when it is necessary to pour the liquid in the thermos cup, the tapered flow channel 41 can play a role in guiding the flow. That is, the design of gradually expanding from the smaller inlet end to the outlet end helps to guide the liquid to flow out smoothly, reducing the resistance and turbulence phenomenon during the liquid flow process, thereby improving the efficiency and stability of pouring water.

[0032] As an implementation manner, as Figure 2 and Figure 5 shown, the connecting cylinder 42 includes a first cylinder section 422 and a second cylinder section 423 connected to each other. From top to bottom, a first external thread 421 and an annular protrusion 424 are sequentially formed on the outer side wall of the first cylinder section 422. The top surface of the annular protrusion 424 is used to abut against the plane where the second opening 22 of the cup lid 20 is located, and the bottom surface of the annular protrusion 424 is used to abut against the plane where the first opening 12 of the cup body 10 is located. A ring-shaped receiving groove 4241 is formed on the bottom surface of the annular protrusion 424. The top of the annular fitting portion 43 is inserted into the ring-shaped receiving groove 4241 and fixedly connected to the bottom of the ring-shaped receiving groove 4241. Along the direction from the cup body 10 to the cup lid 20, the cross-sectional area of the second cylinder section 423 gradually increases, so that the flow channel 41 can form a tapered structure.

[0033] Among them, through the abutting design of the top surface of the annular protrusion 424 against the cup lid 20 and the bottom surface against the cup body 10, liquid leakage can be effectively prevented, ensuring the sealing performance of the thermos cup.

[0034] Among them, the way to achieve fixed connection can be ultrasonic welding, can be hot plate welding, can be laser welding, or can also be two-color injection molding. The present disclosure does not limit this.

[0035] As an implementation manner, as Figure 2 、 Figure 3 and Figure 5 shown, the connecting member 40 further includes a first sealing ring 46. A first annular buckling portion 47 is formed on the inner wall at the bottom end of the annular fitting portion 43. The first annular buckling portion 47 is used to buckle with a second annular buckling portion 32 located at the open end of the containing liner 30. The inner wall of the annular fitting portion 43, the bottom of the ring-shaped receiving groove 4241, the outer wall of the second cylinder section 423, and the top surface of the second annular buckling portion 32 together define a receiving space 48 for accommodating the first sealing ring 46.

[0036] Among them, the cooperation between the first annular buckling part 47 and the second annular buckling part 32 can further enhance the reliability and stability between the receiving bladder 30 and the connecting member 40, can play a primary sealing role, and can prevent the liquid in the receiving bladder from leaking out through the gap.

[0037] Since the connecting member 40 (specifically referring to the second cylinder section 423 and the annular mating part 43) will have the phenomenon of thermal expansion and contraction during the injection molding process, and the specific position of the thermal expansion and contraction cannot be determined, therefore, a first sealing ring 46 (which can be understood as a compensation ring or a buffer ring) can be arranged between the second cylinder section 423 and the annular mating part 43. It can not only absorb the shrinkage difference between the second cylinder section 423 and the annular mating part 43, prevent deformation or gaps caused by uneven shrinkage, but also play a buffering role during the cooling process, can reduce the internal stress generated by shrinkage, and can avoid defects such as cracks in the material interior.

[0038] In addition, the first sealing ring 46 can further enhance the sealing performance between the connecting member 40 (especially the annular mating part 43), the second cylinder section 423 and the receiving bladder 30, play a secondary sealing role, and can further prevent the liquid in the receiving bladder 30 from leaking out through the gap.

[0039] As an implementation manner, as Figure 1 shown, a plurality of grooves 4242 are formed on the outer side wall of the annular protrusion 424, and the plurality of grooves 4242 are arranged at intervals along the circumferential direction of the annular protrusion 424. Among them, the diameters of both the cup body 10 and the cup lid 20 are smaller than the diameter of the annular protrusion 424.

[0040] By providing the grooves 4242, arranging a plurality of grooves 4242 on the outer side wall of the annular protrusion 424 can increase the surface friction force, making it easier for the user to apply force when rotating the cup lid 20 or the cup body 10, thus facilitating the installation and disassembly operations.

[0041] Among them, since the diameters of both the cup body 10 and the cup lid 20 are smaller than the diameter of the annular protrusion 424, that is, the annular protrusion 424 will form an obvious "step" structure between the two, which can provide a clear separation both visually and physically. Such a setting helps the user to avoid accidentally touching the cup lid 20 or the cup body 10 during use and causing misoperations. For example, when the user unscrews the cup lid 20, accidentally touching the cup body 10 may cause the cup body 10 to disengage from the connecting member 40.

[0042] As an implementation manner, as Figures 2 to 4As shown, the multifunctional vacuum cup further includes a gear member 50. The gear member 50 has an unlocked state and a locked state. The gear member 50 includes a ring body 51, a cross member 52, and a second sealing ring 53. From top to bottom, an annular groove 54 and a sliding groove 55 are sequentially formed on the outer side wall of the ring body 51. The sliding groove 55 includes a first part 551 and a second part 552 arranged up and down. The first end of the first part 551 is connected to the second part 552. Among them, the perimeter of the first part 551 is greater than the perimeter of the second part 552. A sliding block 49 is arranged on the channel wall of the flow channel 41, and the sliding block 49 is in sliding fit with the sliding groove 55. In the unlocked state, the sliding block 49 is located in the second part 552; on the outer side wall of the ring body 51 in the locked state, the sliding block 49 is located at the second end of the first part 551, and the second sealing ring 53 is arranged in the annular groove 54.

[0043] By providing the cross member 52 which is arranged inside the flow channel 41, the cross member 52 can effectively prevent larger solid substances such as ice cubes and tea bags from falling out of the containing cavity 30. In addition, the detachable design of the cross member 52 facilitates the cleaning of the cross member 52 and the inside of the containing cavity 30.

[0044] Through the mutual cooperation between the provided sliding block 49 and the sliding groove 55, when the gear member 50 is in the unlocked state, the sliding block 49 can be located in the second part 552 or at the first end of the first part 551. The user can pull out the gear member 50 upward, so that the sliding block 49 is separated from the second part 552, thereby facilitating the cleaning of the cross member 52 and the inside of the containing cavity 30. When the gear member 50 needs to be in the locked state, the sliding block 49 can move from the second part 552 in the vertical direction to the first end of the first part 551, and then slide circumferentially to the second end of the first part 551 and stay there. In this way, the gear member 50 can enter the locked state, which can provide stronger stability and sealing effect, and can help prevent loosening or leakage caused by accidental collision or vibration during daily use.

[0045] By providing the second sealing ring 53, it can prevent the liquid in the containing cavity 30 from flowing out through the gap between the gear member 50 and the flow channel 41, and can further enhance the sealing performance of the entire vacuum cup.

[0046] As an implementation manner, the cross member 52 is located outside the ring body 51, and the cross member 52 is connected to the top of the ring body 51.

[0047] As another implementation manner, as Figure 4 shown, the cross member 52 is located inside the ring body 51, and the cross member 52 is connected to the inner wall of the ring body 51.

[0048] Optionally, as Figure 4 shown, an operation part 57 is formed on the top of the cross member 52 and protrudes from the ring body 51.

[0049] The design that the operating portion 57 protrudes from the ring body 51 provides a user with an obvious gripping point or force application point. When the user needs to rotate or adjust the shifting member 50, the user can operate more easily through the operating portion 57, especially when switching between the unlocking and locking states.

[0050] As an implementation method, Figure 4 As shown, there are multiple slide grooves 55, and the multiple slide grooves 55 are arranged at intervals along the circumference of the ring body 51, wherein the number of sliders 49 corresponds to the number of slide grooves 55 one by one.

[0051] The cooperation between the plurality of slide grooves 55 and the plurality of sliders 49, on the one hand, helps to ensure that the stopper 50 can work stably at any rotation angle, and on the other hand, can increase the contact area between the stopper 50 and the connecting member 40, thereby improving the stability and reliability of the overall structure.

[0052] As an implementation method, Figure 2 As shown, the cup cover 20 includes a cover body 23, an inner plug 24 and a third sealing ring 25. The inner plug 24 for adapting to the flow channel 41 is arranged inside the cover body 23, a sponge 27 is arranged inside the inner plug 24, and the lower end of the inner plug 24 is sleeved with the third sealing ring 25.

[0053] When the cup cover 20 is placed on the connecting piece 40 , the inner plug 24 can further enhance the ability to prevent the liquid in the container 30 from leaking.

[0054] Among them, the third sealing ring 25 can further enhance the sealing performance of the entire thermos cup and avoid liquid leakage.

[0055] Among them, the sponge 27 can play a role in heat preservation.

[0056] Alternatively, if Figure 1 and Figure 2 As shown, a handle 26 may be provided on the top of the cover 23 .

[0057] The design of the handle 26 can, on the one hand, make the thermos cup easier to carry, and the user can directly hold the handle 26 with his hand or hang the thermos cup on a backpack, which can increase the convenience of use. On the other hand, the handle 26 can provide an additional grip point, which can reduce the risk of the thermos cup falling due to hand slippage.
