[0013] Furthermore, the suction nozzle includes a main body, a switching engagement part, an air vent engagement part, and a control part. The switching engagement part is located at one end of the main body, the water outlet channel passes through the main body and the switching engagement part, and the air vent engagement part and the control part protrude from opposite sides of the main body. The top side of the limiting part has a receiving groove that matches the main body and the switching mating part. The two opposite sides of the switching mating part are rotatably disposed on the two opposite side walls of the receiving groove. The bottom wall of the receiving groove has a return air part that matches the air hole mating part. The return air part has a return air hole that penetrates the outer cover. In the closed position, the air hole mating part is inserted into and blocks the return air hole. In the open position, the return air hole penetrates the top and bottom sides of the cup lid. The control part protrudes from the receiving groove and is suitable for external force operation. The water outlet is disposed on the bottom wall of the receiving groove.

[0014] Furthermore, the cup lid also includes a support member and a first sealing member. The support member is fixed in the installation space and together with the inner wall of the installation space defines an accommodating space.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0024] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0025] Insulated cups in related technologies generally consist of a cup body and a lid. When in use, the heat of the liquid inside the cup will be transferred to the outside through the lid, causing heat loss and thus affecting the overall heat preservation effect of the insulated cup.

[0026] See appendix Figure 1 To be continued Figure 6 The first aspect of this utility model discloses a cup lid, which includes an outer cover 10 for fastening and sealing the opening of a cup body 81. The cup lid also includes a heat insulation component. The bottom side of the outer cover 10 forms an installation space 13, and the heat insulation component is disposed in the installation space 13. The bottom side of the heat insulation component is spaced apart from the bottom surface of the outer cover 10. The heat insulation component includes a heat insulation layer 40, which is opposite to the top surface of the outer cover 10.

[0027] In this embodiment, the fastening method between the cup lid and the cup body is not specifically limited; it can be either an internal insertion type or an external type.

[0028] The following description uses an internal insertion type as an example. The cup lid includes an outer cover 10 and a second sealing member 30. The second sealing member 30 is sleeved on the outside of the outer cover 10 and is used to form a seal with the inner wall of the cup body 81 when the cup lid is covered on the cup body 81. The cup lid also includes a heat insulation layer 40. The bottom of the outer cover 10 forms an installation space 13. The heat insulation layer 40 is opposite to the top wall of the installation space 13 and is used to prevent heat loss from the bottom of the outer cover 10 to the top of the outer cover 10.

[0029] The cup lid in this embodiment is generally used in insulated containers, such as insulated cups and cold cups.

[0030] In this embodiment, the cup lid is fastened to the cup body 81 by inserting it into the cup body 81. See attached drawing. Figure 1 , 3 This reduces the overall volume of the insulated container. In this embodiment, the second sealing element 30 is generally set as a sealing ring (the specific shape of the sealing ring can be designed according to actual needs). When the cup lid is placed on the cup body 81, the second sealing element 30 is used to seal the mating part 12 of the cup lid and the cup body 81 to prevent heat from the cup body 81 from being lost through the gap of the mating part 12.

[0031] In this embodiment, the heat insulation layer 40 is used to block heat loss from the top side of the cup lid. Combined with the second sealing element 30 and the vacuum insulation effect of the cup body 81, it can block heat loss in all directions, greatly slow down the rate of heat loss, and improve the heat preservation effect.

[0032] This embodiment does not specifically limit the form of the heat insulation layer 40. When setting it, the heat insulation layer 40 can be formed by heat insulation materials, such as foaming agent, cold insulation agent, aerogel, etc., placed inside the outer cover 10. It can also form a structure similar to the vacuum heat insulation of the cup body 81 inside the cup lid, as long as it can prevent heat loss from the bottom of the cup lid to the top of the cup lid.

[0033] In addition, in actual settings, this embodiment does not specifically limit the coverage area of ​​the heat insulation layer 40. The coverage area of ​​the heat insulation layer 40 can completely cover the bottom surface of the cup lid or partially cover it. However, in order to achieve a better heat insulation effect, the coverage area of ​​the heat insulation layer 40 is generally not less than 60% of the opening area of ​​the cup body 81.

[0034] In this embodiment, there is no specific limitation on how the heat insulation layer 40 is set in the installation space 13 of the outer cover 10. In actual installation, it can be directly filled in the installation space 13, or it can be filled in the installation space 13 by other supporting components.

[0035] Since the temperature absorbed by the insulation layer 40 (formed by filling with heat-insulating material) has an upper limit, the temperature will still be lost after the temperature absorbed by the insulation layer 40 reaches the corresponding value. That is, the heat insulation capacity of the insulation layer 40 is related to the thickness of the insulation layer 40. In order to maximize the heat insulation capacity of the lid without affecting the volume of the insulated container, the set interval formed between the bottom side of the insulation component and the bottom surface of the outer cover 10 in this embodiment can generally be controlled between 0 and 10 mm. When the set interval is 0, the bottom surface of the insulation component is flush with the bottom surface of the outer cover 10, which can maximize the use of the installation space volume, maximize the thickness of the insulation layer, and thus improve the heat insulation effect.

[0036] As one embodiment of this utility model, see the appendix. Figure 1 , 3 The outer cover 10 includes a limiting part 11 and a mating part 12. The mating part 12 is disposed on the bottom side of the limiting part 11. The diameter of the mating part 12 is smaller than the diameter of the limiting part 11. The mating part 12 is used to be threadedly connected to the cup body 81. The second sealing member 30 is sleeved on the outside of the mating part 12. The bottom side of the mating part 12 forms the installation space 13.

[0037] In this embodiment, the mating part 12 is inserted into the cup body 81 during use. The outer wall of the mating part 12 has external threads, and the inner wall of the cup body 81 has internal threads that mesh with the external threads, achieving a threaded connection and thus fixing the cup lid onto the cup body 81. The second sealing element 30 is generally located on the top side of the threaded mating part 12 (near the limiting part 11). In this embodiment, the limiting part 11 has a larger diameter. When the lid is closed, the limiting part 11 and the top of the cup body 81 form a limiting position, preventing the entire cup lid from falling into the cup body 81. In actual installation, a plastic protective layer 60 can also be covered on the top and sides of the limiting part 11. (See attached diagram.) Figure 1 This allows the operator to directly turn the knob and improves the comfort of turning it.

[0038] In this embodiment, the mating part 12 forms an installation space 13. Since the mating part 12 is inserted into the cup body 81, the heat insulation layer 40 is also placed inside the cup body 81. The heat insulation layer 40 overlaps with the peripheral vacuum structure of the cup body 81, which can better prevent heat loss.

[0039] As one embodiment of this utility model, see the appendix. Figure 1A water outlet protrusion 14 protruding into the installation space 13 is formed on the top wall of the installation space 13. A water outlet hole 521 is formed on the top surface of the limiting part 11, which passes through the water outlet protrusion 14 along the axial direction. The heat insulation layer 40 is arranged around the water outlet protrusion 14. The cup lid also includes a water absorption component 50, which is used to make the water outlet hole 521 pass through or block the water outlet hole 521.

[0040] The cup lid in this embodiment includes a water-absorbing component 50, which can absorb the liquid inside the cup body 81 without opening the cup lid. This can reduce the large heat loss caused by fully opening the cup lid and also achieve a better heat preservation effect.

[0041] In this embodiment, the heat insulation layer 40 is arranged around the water outlet protrusion 14, which can block heat loss to the greatest extent. This embodiment does not limit the specific setting position of the water outlet protrusion 14. In actual setting, the water outlet protrusion 14 can be set at the center of the cup lid (at this time, the heat insulation layer 40 can form a ring around the water outlet protrusion 14) or at a position away from the center of the cup lid. As shown in the figure, in this embodiment, the water outlet protrusion 14 is set at a position away from the center of the cup lid. At this time, the heat insulation layer 40 forms a U-shaped opening, and the water outlet protrusion 14 is set in this U-shaped opening.

[0042] In this embodiment, the water-absorbing component 50 can open and close the water outlet 521 as needed, making it convenient to use the liquid in the cup body 81 without opening the cup lid. The diameter of the water outlet 521 is smaller than the diameter of the cup lid, which can greatly reduce heat loss during use. Moreover, when not in use, the water outlet 521 can be blocked to achieve a heat preservation effect.

[0043] This embodiment does not specifically limit how the water absorption component 50 opens or blocks the water outlet 521. When setting it up, different working states can be switched by rotating or sliding.

[0044] As one embodiment of this utility model, see the appendix. Figure 1 , 3 4. The water-absorbing assembly 50 includes a nozzle 51, an adapter pipe 52, and a suction tube 53. The adapter pipe 52 is axially nested within the water outlet mounting hole, and its central cavity forms a water outlet 521. The bottom side of the adapter pipe 52 is connected to the suction tube 53, which communicates with the water outlet 521. The nozzle 51 is rotatably disposed on the top side of the limiting part 11, with one end of the nozzle 51 facing the top surface of the adapter pipe 52. A through water outlet channel 515 is formed on the nozzle 51, and the nozzle 51 can rotate between an open and closed position under external force. In the open position, the water outlet channel 515 and the water outlet hole 521 are interconnected; In the closed position, the suction nozzle 51 blocks the water outlet 521.

[0045] In this embodiment, the specific structure of the water absorption component 50 is defined. The suction nozzle 51 switches between the open and closed positions by rotation. In this embodiment, the adapter pipe 52 can be set as a rubber tube, which can seal the water outlet installation hole. Furthermore, a groove or boss that cooperates with the adapter pipe 52 can be set in the water outlet installation hole to improve the installation stability and sealing effect of the adapter pipe 52.

[0046] As one embodiment of this utility model, see the appendix. Figure 1 To be continued Figure 5 The suction nozzle 51 includes a main body 512, a switching engagement part 511, an air vent engagement part 513, and a control part 514. The switching engagement part 511 is disposed at one end of the main body 512, and the water outlet channel 515 passes through the main body 512 and the switching engagement part 511. The air vent engagement part 513 and the control part 514 protrude from opposite sides of the main body 512. The top side of the limiting part 11 is formed with a receiving groove 111 that matches the main body part 512 and the switching mating part 511. The two opposite sides of the switching mating part 511 are rotatably disposed on the two opposite side walls of the receiving groove 111. The bottom wall of the receiving groove 111 is provided with a return air part 112 that matches the air hole mating part 513. The return air part 112 is formed with a return air hole 113 that penetrates the outer cover 10. In the closed position, the air hole mating part 513 is inserted into and blocks the return air hole 113. In the open position, the return air hole 113 penetrates the top and bottom sides of the cup lid. The operating part 514 protrudes from the receiving groove 111 and is suitable for external force operation. The water outlet 521 is disposed on the bottom wall of the receiving groove 111.

[0047] For a diagram showing the state of the suction nozzle 51 in the closed position in this embodiment, please refer to the attached diagram. Figure 1 As can be seen, the spout 51 is completely hidden inside the cup lid, which reduces the volume of the insulated container and makes it convenient to carry and store. When in use, the spout 51 is rotated to a vertical position, making it convenient for the user to drink directly.

[0048] In this embodiment, the air return fitting part 12 can block the air return hole 113 in the closed position when water is absorbed, thus ensuring the heat preservation effect. In the open position of the suction nozzle 51, the air return hole 113 is opened, and the space inside the cup body 81 is connected to the outside, ensuring air pressure balance and smooth water flow. The state of the suction nozzle 51 in the closed position in this embodiment is shown in the attached figure. Figure 1 At this time, the control part 514 protrudes from the top side of the outer cover 10, making it convenient for the operator to rotate the suction nozzle 51 to the open position.

[0049] In this embodiment, the switching mating part 511 of the suction nozzle 51 can be configured as a cylindrical structure, wherein the top surface of the adapter pipe 52 forms a structure that mates with the cylindrical surface, which helps to improve the smoothness of the rotation of the suction nozzle 51 and better sealing.

[0050] In this embodiment, the suction nozzle 51 is in the closed position, see attached... Figure 1 At this time, the water outlet end of the water outlet channel 515 is also placed in the receiving tank 111, which can play a certain protective effect on the water outlet channel 515 and prevent dust or other impurities from entering the water outlet channel 515.

[0051] As one embodiment of this utility model, see the appendix. Figure 1 The heat insulation assembly further includes a support member 20 and a first sealing member 70. The support member 20 is disposed within the installation space 13 and is fixedly connected to the outer cover 10. The support member 20 and the inner wall of the installation space 13 together limit the accommodating space 24. The heat insulation layer 40 is disposed within the accommodating space 24. The first sealing member 70 is disposed between the support member 20 and the outer cover 10 and seals the accommodating space 24. The bottom surface of the support member 20 and the surface of the outer cover 10 form the predetermined interval.

[0052] In this embodiment, the support member 20, the outer cover 10, and the first sealing member 70 together define a sealed receiving space 24. This embodiment does not specifically limit the structure of the support member 20; in actual installation, the support member 20 can be configured as a flat plate structure or a box structure (as shown in the attached diagram). Figure 5 As shown, it is sufficient as long as it can form a sealed containment space 24 with the outer cover 10 to fill the heat insulation layer 40.

[0053] The structure of one embodiment of the support member 20 in this embodiment is shown in the appendix. Figure 1 , 3The support member 20 includes a base plate 21 and an annular side plate 22. The annular side plate 22 is disposed on the top side of the base plate 21 and limits the storage space with the top opening of the base plate 21. When the support member 20 is installed in the installation space 13, the top of the annular side plate 22 abuts against and is fixedly connected to the top wall of the installation space 13, and together they define the receiving space 24. During production, insulation material can be filled into the storage space of the support member 20 to form a heat insulation layer 40. A sealing groove 23 is formed on the top surface of the annular side plate 22. A first sealing element 70 (generally a sealing ring) is disposed in the sealing groove 23 to seal the receiving space 24. This can prevent moisture from entering the receiving space 24 during use and affecting the performance of the heat insulation layer 40.

[0054] In this embodiment, the support member 20 and the outer cover 10 can be fixed by an interference fit or by ultrasonic welding.

[0055] The second aspect of this application discloses a thermal insulation container, see appendix. Figure 6 The cup includes a cup body 81 and a cup lid. The cup lid is the type described in the first aspect. One bottom end of the outer cover 10 is inserted into the cup body 81. The second sealing member 30 is sealed to the inner wall of the cup body 81. The heat insulation layer 40 is used to prevent heat from the cup body 81 from escaping from the top side of the cup lid.

[0056] In this embodiment, the insulated container, with the cooperation of the lid and the body 81, can achieve all-round heat insulation of the inner cavity of the body 81, significantly improving the heat preservation performance. A handle 82 can be provided on the outer side of the body 81 of the insulated container in this embodiment, or a handle 82 for easy lifting can be provided on the lid.
