By providing the first stop portion and the second stop portion, the axial movement stroke of the fastener is limited, which can prevent the fastener from falling out of the hole position after loosening and improve the installation reliability; by providing the third sealing ring, steam or slurry and cleaning water in the cup body can be prevented from entering between the metal lower cover and the cup cover, ensuring the cleanliness inside the cup cover assembly.

[0025] 7. As a preferred embodiment, the cup lid includes a radially outwardly protruding portion. The metal upper lid includes a metal upper lid top wall and a metal upper lid peripheral side wall. A notch is provided on one side of the metal upper lid peripheral side wall corresponding to the protruding portion. A protrusion extending towards the notch is provided at the connection between the protruding portion and the cup lid. The protrusion is inserted and matched with the notch. The setting of the protruding portion is used to cooperate with the handle on the cup body. By inserting and matching the protrusion with the notch, the metal upper lid can be prevented from rotating and shifting in the circumferential direction, so as to ensure the fixing effect and sealing effect between the metal upper lid and the cup lid.

[0026] 8. As a preferred embodiment, the lower end of the metal lower lid extends downward relative to the cup lid. A first outwardly turned edge is provided at the bottom end of the cup lid, and a second outwardly turned edge is provided at the bottom end of the metal lower lid. A cup lid sealing ring is clamped between the first outwardly turned edge and the second outwardly turned edge. Thus, the downwardly extending part of the metal lower lid can extend into the cup body.

[0044] As Figures 1 to 7 shown, this application provides a stirring cup lid, which includes a cup lid 10, a metal upper lid 11 fixed on the outer side of the cup lid 10, and a metal lower lid 12 fixed on the inner side of the cup lid 10. The cup lid 10 is provided with a feeding port 101. The metal upper lid 11 and the metal lower lid 12 are respectively provided with an upper avoidance port 111 and a lower avoidance port 121 communicating with the feeding port 101. The metal upper lid 11 is fixed on the outer top surface 102 of the cup lid 10 through an upper fixing structure, and the metal lower lid 12 is fixed on the inner bottom surface 103 of the cup lid 10 through a lower fixing structure.

[0045] For the stirring cup lid of the present utility model, it is only necessary to fix the metal upper lid 11 and the metal lower lid 12 to the cup lid 10 respectively. It uses fewer accessories, has a simple structure, is convenient for installation, and can reduce costs. Moreover, the metal upper lid 11 and the metal lower lid 12 are respectively arranged on the outer top surface 102 and the inner bottom surface 103 of the cup lid 10, and they do not contact each other. The stirring cup lid has a sufficient thickness in the horizontal area including the feeding port 101, which is beneficial to blocking noise and reducing the magnitude of the noise transmitted upward, and the heat insulation effect is enhanced, which can prevent users from being scalded when operating the feeding lid, thus improving the user experience.

[0046] As Figure 1 shown, the metal upper lid 11, the cup lid 10, and the metal lower lid 12 are distributed from top to bottom. The metal upper lid 11 is snap-fitted and installed with the cup lid 10 from above, and the metal lower lid 12 is inserted into the inside of the cup lid 10 from below for installation. The installation process is smooth and simple, which is beneficial to improving the installation efficiency while reducing the structural cost. Preferably, the metal upper lid 11, the cup lid 10, and the metal lower lid 12 all have a top wall structure and a side wall structure. The side wall of the metal upper lid 11 covers the outside of the upper end side wall of the cup lid 10, and at least part of the side wall of the metal lower lid 12 is embedded inside the side wall of the cup lid 10. After the three are assembled, they form Figure 2 such a structure. As Figure 3 shown, the top wall of the cup lid 10 has a suitable thickness, for example, which can isolate the metal upper lid 11 and the metal lower lid 12. In this way, the stirring cup lid has a certain horizontal thickness to enhance heat insulation and noise reduction. Further, one or more upper fixing structures can be provided to improve the fixing effect between the metal upper lid 11 and the cup lid 10; one or more lower fixing structures can be provided to improve the fixing effect between the metal lower lid 12 and the cup lid 10. When the stirring cup lid is in use, the cup body can be closed by installing a feeding lid at the feeding port 101. The feeding lid can be installed at the feeding port 101 through the upper avoidance opening 111, and the lower end of the feeding lid can be lower than or higher than the lower avoidance opening 121.

[0047] As a preferred embodiment, the upper fixing structure includes a glue groove provided on the outer top surface 102 of the cup lid 10, and the metal upper lid 11 is fixed to the cup lid 10 through the glue material provided in the glue groove. In this embodiment, the metal upper lid 11 is fixed by gluing, and only a glue groove needs to be opened on the cup lid 10, which is beneficial to simplifying the structure of the metal upper lid 11.

[0048] As Figure 3 shown, the outer top surface 102 of the cup lid 10 adopts a non-planar structure, and the outer top surface 102 protrudes with protrusions, and the protrusions are recessed to form glue grooves. During installation, glue material is filled in the glue grooves and then the metal upper lid 11 is buckled on.

[0049] As a preferred embodiment of the present embodiment, the glue groove includes an annular first glue groove 104 and a second glue groove 105. The first glue groove 104 is arranged close to the center of the cup lid 10, and the second glue groove 105 is arranged close to the edge of the cup lid 10. By providing at least two circles of glue grooves, the fixing area can be increased, and the fixing tightness between the metal upper cover 11 and the cup lid 10 in the radial direction can be ensured, avoiding the local warping of the metal upper cover 11, which may weaken the sealing effect between the metal upper cover 11 and the cup lid 10 and cause water to enter between them during cleaning.

[0050] As Figure 3 or Figure 5 shown, the first glue groove 104 is in the inner circle and the second glue groove 105 is in the outer circle. By means of the annular glue grooves, on the premise of meeting the circumferential fixing effect, the glue grooves at different radial positions can ensure the uniformity of fixing in the radial direction, and the overall fixing effect of the metal upper cover 11 can be improved. The heights of the first glue groove 104 and the second glue groove 105 are not limited in this application and can be set according to actual needs. For example, when the top wall of the metal upper cover 11 has a height change in the radial direction, the first glue groove 104 and the second glue groove 105 are set at different heights to match the shape of the metal upper cover 11 and ensure the fixing effect with less glue material.

[0051] It can be understood that the glue grooves are not limited to two circles, and can also be set to more than three circles. The distribution form of the glue grooves is not limited to annular, and can also be multiple arcs or other shapes arranged at intervals in the circumferential direction.

[0052] As a preferred embodiment, the upper fixing structure includes a pressing block 13. The pressing block 13 includes a flat pressing portion 131 and an installation portion 132 extending downward from the pressing portion 131. The cup lid 10 is provided with an installation groove 106. The installation portion 132 passes through the upper avoidance opening 111 and is inserted into the installation groove 106, and the pressing portion 131 abuts against the outer top wall of the metal upper cover 11 to press the metal upper cover 11 against the cup lid 10. Using the pressing block 13 to press the metal upper cover 11 against the cup lid 10 can achieve the axial limit of the metal upper cover 11, with reliable fixing. And because the pressing block 13 is arranged close to the feeding port 101, it can ensure that the metal upper cover 11 and the cup lid 10 are closely attached at the position close to the feeding port 101, preventing the steam overflowing from the feeding port 101 from entering the interior of the two through the fitting gap between the metal upper cover 11 and the cup lid 10, thus strengthening the sealing effect between the two.

[0053] As Figure 1 or Figure 3As shown, during specific installation, first cover the metal upper cover 11 on the top of the cup cover 10, and then press-fit the pressing block 13. The pressing block 13 is welded by ultrasonic waves to connect the metal upper cover 11 and the cup cover 10 into one body. To ensure the fixing strength between the metal upper cover 11 and the cup cover 10, before installing the pressing block 13, the metal upper cover 11 and the cup cover 10 can be pre-fixed through other upper fixing structures, such as the above-mentioned glue groove structure or other fixing structures.

[0054] As a preferred embodiment, the metal upper cover 11 includes an annular upper cover body 112, a first fastening portion 113 extending downward from the inner peripheral edge of the upper cover body 112, and a second fastening portion 114 extending downward from the outer peripheral edge of the upper cover body 112. A first sealing ring 14 and a second sealing ring 15 are provided between the metal upper cover 11 and the cup cover 10. The first sealing ring 14 is radially abutted against the inner wall of the first fastening portion 113, and the second sealing ring 15 is radially abutted against the inner wall of the second fastening portion 114. By sealing the metal upper cover 11 and the cup cover 10 respectively at the inner and outer circles, the sealing effect can be improved, water ingress between the metal upper cover 11 and the cup cover 10 can be prevented when cleaning the cup cover 10 assembly, and steam overflowing from the feeding port 101 can also be prevented from entering between the metal upper cover 11 and the cup cover 10, which can avoid the generation of bacteria due to water accumulation between the metal upper cover 11 and the cup cover 10, improve the hygiene of use, and the metal upper cover 11 and the cup cover 10 achieve soft contact through the sealing ring, which is beneficial to reducing wear between components.

[0055] As Figure 1 and Figure 3 shown, to facilitate the installation of the first sealing ring 14 and the second sealing ring 15, the cup cover 10 is provided with a first groove portion 22 for embedding the first sealing ring 14 and a second groove portion 23 for embedding the second sealing ring 15. During installation, first press the first sealing ring 14 and the second sealing ring 15 into the first groove portion 22 and the second groove portion 23 respectively, and then fasten the metal upper cover 11. Preferably, the first sealing ring 14 is provided with a sealing rib abutting against the lower surface of the metal upper cover 11, and the second sealing ring 15 is provided with a sealing rib abutting against the inner side wall of the metal upper cover 11 to improve the sealing effect.

[0056] As a preferred embodiment, an installation cavity 107 is formed by enclosing the inner bottom surface 103 of the cup cover 10 and the side wall of the cup cover 10. The metal lower cover 12 is embedded in the installation cavity 107, and the side wall of the metal lower cover 12 is in interference fit or snap-fit with the side wall of the cup cover 10. The setting of the installation cavity 107, on the one hand, provides an installation position for the metal lower cover 12, and on the other hand, the installation cavity 107 can form a part of the crushing space, which is beneficial to improving the crushing effect and reducing the probability of slurry overflow; the interference fit or snap-fit between the side wall of the metal lower cover 12 and the side wall of the cup cover 10 realizes the radial limit of the two, which can be used as pre-fixing and provides favorable conditions for the subsequent fixing of the two, and can prevent the metal lower cover 12 from falling out during the fixing process.

[0057] In one embodiment, as Figure 6 and Figure 7 shown, a convex portion 108 is provided on the side wall of the cup lid 10, and a concave portion 122 is provided on the side wall of the metal lower lid 12. The pre - fixation of the metal lower lid 12 and the cup lid 10 can be achieved through the cooperation of the convex portion 108 and the concave portion 122.

Thus, the metal lower lid 12 and the cup lid 10 are locked axially by the fastener 16, with strong fixing firmness, and the metal lower lid 12 can be prevented from falling out during use.

[0059] In one embodiment, the fastener 16 is, for example, a screw. By using the method of screwing in the screw, the structure is simple, the installation is convenient, and the fixation is reliable.

[0060] As a preferred embodiment of this embodiment, a first stop portion 163 is provided at the upper end of the fastener 16, and a second stop portion 164 is provided at the lower end of the fastener 16. The first stop portion 163 is clamped at the upper peripheral edge of the mounting hole 109, and the second stop portion 164 is clamped at the lower peripheral edge of the through - hole 123. A third sealing ring 21 is provided between the second stop portion 164 and the top wall of the metal lower lid 12. By providing the first stop portion 163 and the second stop portion 164, the axial movement stroke of the fastener 16 is restricted, and the fastener 16 can be prevented from falling out of the hole position after loosening, improving the installation reliability; by providing the third sealing ring 21, the steam or slurry in the cup body and the cleaning water can be prevented from entering between the metal lower lid 12 and the cup lid 10, ensuring the cleanliness inside the cup lid 10 assembly.

[0061] Exemplarily, as Figure 4 shown, the fastener 16 includes a first part 161 and a second part 162 connected by threading. The top end of the first part 161 is provided with the first stop portion 163 and the outer wall of the first part 161 is provided with an external thread. The bottom end of the second part 162 is provided with the second stop portion 164 and the inner wall of the second part 162 is provided with an internal thread. The diameter of the first stop portion 163 is larger than the diameter of the mounting hole 109, and the diameter of the second stop portion 164 is larger than the diameter of the through - hole 123. During installation, the first part 161 is inserted downward into the mounting hole 109 from above the mounting hole 109, and the second part 162 is inserted into the mounting hole 109 from below the through - hole 123 and thread - locked with the first part 161.

[0062] As a preferred embodiment, the cup lid 10 includes a radially outwardly protruding portion 17. The metal upper lid 11 includes a top wall of the metal upper lid 11 and a circumferential side wall of the metal upper lid 11. A notch is provided on one side of the circumferential side wall of the metal upper lid 11 corresponding to the protruding portion 17. A protrusion extending towards the notch is provided at the connection between the protruding portion 17 and the cup lid 10. The protrusion is in plug-in fit with the notch. The setting of the protruding portion 17 is used to cooperate with the handle on the cup body. Through the plug-in fit between the protrusion and the notch, the metal upper lid 11 can be prevented from rotating and shifting in the circumferential direction, so that the fixing effect and sealing effect between the metal upper lid 11 and the cup lid 10 can be ensured. The shapes of the protrusion and the notch are adapted to achieve anti-rotation.

[0063] Further, as Figure 1 and Figure 3 shown, a decorative cover 171 is snap-fitted and installed above the protruding portion 17, and a tail cover 172 for snap-fitting with both is provided at the outer ends of the decorative cover 171 and the protruding portion 17.

[0064] As a preferred embodiment, the lower end of the metal lower lid 12 extends downward relative to the cup lid 10. A first outwardly turned edge 18 is provided at the bottom end of the cup lid 10, and a second outwardly turned edge 19 is provided at the bottom end of the metal lower lid 12. A cup lid sealing ring 20 is clamped between the first outwardly turned edge 18 and the second outwardly turned edge 19. As Figure 3 shown, the portion of the metal lower lid 12 extending downward can extend into the cup body. The probability of deformation of the metal material under the influence of high temperature is small, which can reduce the heat transfer from the cup body to the cup lid 10 and thus reduce the probability of deformation of the cup lid 10. Moreover, by clamping the cup lid sealing ring 20 between the first outwardly turned edge 18 and the second outwardly turned edge 19, the reliability of the installation of the cup lid sealing ring 20 can be improved, and the cup lid sealing ring 20 can be prevented from falling off or slipping, which affects the sealing at the cup mouth.

[0065] It can be understood that when the stirring cup lid of the present application is used in cooperation with the cup body, when the stirring cup lid is closed in place, it can be that only the portion of the metal lower lid 12 extending downward extends into the cup body, or it can be that the side wall portion of the cup lid 10 extends into the cup body. Due to the barrier of the cup lid sealing ring 20, the heat transfer from the cup body to the cup lid 10 can be reduced, so that the probability of the cup lid 10 being deformed by heat can be reduced, which is beneficial to extending its service life.

[0066] The technical solution protected by the present utility model is not limited to the above embodiments. It should be noted that the combination of the technical solution of any one embodiment with the technical solutions of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all belong to the scope required to be protected by the present utility model.
