[0055] See also Figures 1 to 6 , the cup cover assembly 100 includes a fixing member 21, a moving coil 22 and a sealing ring 23, and the moving coil 22 can move relative to the fixing member 21. In some embodiments, the moving coil 22 can move up and down relative to the fixing member 21, but is not limited thereto. One end of the sealing ring 23 is fixed to the fixing member 21, and the other end is fixed to the moving coil 22. By driving the moving coil 22 to move, the sealing ring 23 can be switched between the first state and the second state. In some embodiments, the sealing ring 23 cooperates with the inner wall of the stirring cup 80 to seal in the first state, and the sealing ring 23 is separated from the inner wall of the stirring cup 80 in the second state. In other embodiments, the contact force of the sealing ring 23 with the stirring cup 80 in the first state is greater than the contact force of the sealing ring with the stirring cup 80 in the second state. In this way, the cup cover assembly 100 can be easily and conveniently removed.

[0056] In a preferred embodiment, the inner diameter of the mixing cup 80 gradually decreases from top to bottom. In this way, the moving coil moves downward by the same distance, so that the sealing ring and the inner wall of the mixing cup can fit more tightly. In other embodiments, the inner diameter of the mixing cup 80 at different positions in the vertical direction remains consistent.

[0057] When the cup cover assembly 100 needs to be removed, the sealing ring 23 is switched from the first state to the second state, so that the sealing ring 23 no longer contacts the inner wall of the mixing cup 80 or the contact force becomes smaller, thereby achieving easy and labor-saving removal of the cup cover assembly 100 from the mixing cup 80.

[0058] In one embodiment, the outer diameter of the sealing ring 23 in the first state is greater than the outer diameter of the sealing ring 23 in the second state. In this way, when the sealing ring 23 is in the second state, the cup cover assembly 100 can be easily removed.

[0059] The cup cover assembly 100 also includes a driving mechanism 40, which is used to drive the moving coil 22 to move relative to the fixing member 21, thereby prompting the sealing ring 23 to switch between the first state and the second state. In this way, it is more convenient to drive the moving coil 22 to move relative to the fixing member 21. In the illustrated embodiment, the driving mechanism 40 is used to drive the moving coil 22 to move up and down relative to the fixing member 21, thereby prompting the sealing ring 23 to switch between the first state and the second state. In other embodiments, the driving mechanism 40 can also be used to drive the moving coil 22 to move radially, thereby prompting the sealing ring 23 to switch between the first state and the second state. The above are just some examples and are not limited to the above examples.

[0060] The driving mechanism 40 includes any one of the following: a cam mechanism, a rack and pinion mechanism, and a connecting rod mechanism, but is not limited thereto.

[0061] In the illustrated embodiment, the moving coil 22 and the fixing member 21 are both annular, and the moving coil 22 is disposed outside the fixing member 21. In another embodiment, the moving coil 22 is disposed inside the fixing member 21. In other embodiments, the moving coil 22 is disposed below the fixing member 21. This is not limited thereto.

[0062] The cup cover assembly 100 further includes an exhaust cover 70, which is installed inside the fixing member 21, that is, the fixing member 21 surrounds the exhaust cover 70. The fixing member 21 is provided with a support portion 216 protruding inwardly, and the exhaust cover 70 is supported by the support portion 216.

[0063] The cup cover assembly also includes a cup cover 10, and the cup cover 10 includes a cover body 11 surrounding the fixing member 21. The cover body 11 is fixedly matched with the fixing member 21; or, the cover body 11 and the fixing member 21 are integrally formed, so that food and the like can be prevented from entering the inner side of the cup cover 10. The cup cover 10 also includes a cover plate 12 that is mounted together with the cover body 11. The cover body 11 and the cover plate 12 are annular. The cover body 11 and the cover plate 12 can be fixed together by a snap structure, a locking member, or the like. In the illustrated embodiment, the cover plate 12 is provided with a snap, and the cover body 11 is provided with a slot that corresponds to the snap, but is not limited thereto.

[0064] In the illustrated embodiment, the cover body 11 is provided with a central hole 115 for the fixing member 21 to pass through, and a plurality of buckles 219 are provided at the upper end of the fixing member 21. The cover body 11 is correspondingly provided with a slot 119 that cooperates with the buckle 219. The buckle 219 cooperates with the slot 119 to fix the cover body 11 and the fixing member 21 together. Of course, the cover body 11 and the fixing member 21 can also be fixed and matched by other fixing methods, such as fasteners, threaded structures, riveting, etc., but are not limited thereto. In another embodiment, the cover body 11 and the fixing member 21 are integrally formed.

[0065] The cover 11 covers the upper part of the moving coil 22. Since the cover 11 is fixedly matched with the fixing member 21 and the cover 11 covers the moving coil 22, the food overflowing from the exhaust passage is not easy to enter the interior of the cup cover assembly 100, so that the interior of the cup cover assembly 100 can be kept clean during use and is easy to clean. Figure 3 An annular recess 215 is provided on the outer side of the top of the fixing member 21, and an annular protrusion 1150 matching with the recess 215 is correspondingly provided on the inner side of the cover body 11, so that the cover body 11 and the fixing member 21 can be matched more closely.

[0066] The fixing member 21 includes an annular first body portion 217 and a first mounting portion 218 disposed on the first body portion 217 . One end of the sealing ring 23 is fixed to the first mounting portion 218 .

[0067] The moving coil 22 is located above the first mounting portion 218. In this way, when the inner diameter of the mixing cup 80 gradually decreases from top to bottom, the moving coil 22 moves downward by the same distance, so that the sealing ring 23 can be more closely matched with the inner wall of the mixing cup 80. The first mounting portion 218 is formed by radially protruding outward from the first body portion 217.

[0068] The moving coil 22 includes an annular second body portion 227 and a second mounting portion 228 disposed on the second body portion 227. The other end of the sealing ring 23 is fixed to the second mounting portion 228. In the illustrated embodiment, the second mounting portion 228 is formed by protruding radially outward from the second body portion 227.

[0069] The first mounting portion 218 is provided with a first clamping groove 211, and the sealing ring 23 is provided with a first clamping portion 231 that matches the first clamping groove 211; and / or, the second mounting portion 228 is provided with a second clamping groove 221, and the sealing ring 23 is provided with a second clamping portion 232 that matches the second clamping groove 221. In this way, the sealing ring 23 is easy to assemble and has low cost. The sealing ring 23 also includes a main body 233 connecting the first clamping portion 231 and the second clamping portion 232, and the main body 233 protrudes outward.

[0070] As the moving coil 22 moves up and down relative to the fixing member 21, the distance between the first clamping portion 231 and the second clamping portion 232 increases or decreases accordingly, and accordingly, the outer diameter of the main body 233 also decreases or increases accordingly. When the sealing ring 23 is in the first state, the main body 233 cooperates with the inner wall of the stirring cup 80 to form a seal. When the sealing ring 23 switches to the second state, the outer diameter of the main body 233 decreases, so that the main body 233 does not contact the inner wall of the stirring cup 80 or the contact force decreases, thereby facilitating the removal of the cup cover assembly 100.

[0071] The opening direction of the first card slot 211 is radially outward, and / or the opening direction of the second card slot 221 is radially outward. In this way, the first clamping portion 231 is more stably and reliably installed in the first card slot 211, the second clamping portion 232 is more stably and reliably installed in the second card slot 221, and the assembly is more convenient. In the illustrated embodiment, the opening directions of the first card slot 211 and the second card slot 221 are both radially outward.

[0072] The cup cover assembly also includes a rotating shaft 55, which drives the rotating shaft 55 to rotate to drive the driving mechanism to move. In this way, the driving mechanism is driven by the rotating shaft 55, and the operation is more convenient. The cup cover assembly 100 also includes a handle 50, and the two ends of the handle 50 are respectively installed in cooperation with the cover body 11 through the rotating shaft 55. In this way, the user takes off the cup cover assembly 100 by holding the handle 50, and the operation is more convenient. In the illustrated embodiment, the handle 50 is arc-shaped, and the two ends of the handle 50 are respectively fixedly connected to two rotating shafts 55, and the rotating shaft 55 is rotatably arranged on the cover body 11. The handle 50 has a folded position and an operating position, and the handle 50 switches between the folded position and the operating position by rotation.

[0073] The cover body 11 includes a main body 118 and a mounting portion 111 extending downward from the main body 118, and the rotating shaft 55 is rotatably disposed on the mounting portion 111. The cover body 11 also includes a receiving space 116 recessed downward from the main body 118, and the handle 50 can be accommodated in the receiving space 116. In this way, the cup cover assembly 100 has a compact and beautiful appearance. In the illustrated embodiment, the cover body 11 is radially symmetrically provided with two mounting portions 111, which are respectively mounted in cooperation with the two ends of the handle 50.

[0074] When the handle 50 is in the folded position, the handle 50 is located in the accommodating space 116, and the handle 50 and the main body 118 of the cover body 11 are substantially located in the same plane. When the handle 50 is in the operating position, the handle 50 is arranged across the exhaust cover 70, and the two ends of the handle 50 are located at the two ends of the exhaust cover 70. At this time, the cup cover assembly 100 can be removed by applying an upward force to the handle 50.

[0075] In the illustrated embodiment, the driving mechanism 40 includes a gear 41 disposed on the rotating shaft 55 and a rack 42 disposed on the moving coil 22, and the gear 41 and the rack 42 are meshed with each other. The rack 42 can be fixed to the moving coil 22 or formed integrally with the moving coil 22. The gear 41 can be fixed to the rotating shaft 55 or formed integrally with the rotating shaft 55. In this way, by operating the handle 50 to control the gear 41 to rotate in different directions, the moving coil 22 can be moved upward or downward, thereby switching the sealing ring 23 between the first state and the second state.

[0076] In the illustrated embodiment, the moving coil 22 is symmetrically provided with two racks 42 . The moving coil 22 further includes an extension portion 224 extending radially inward from the second body portion 227 , and the racks 42 are disposed on the extension portion 224 .

[0077] When the handle 50 is in the folded position, the gear 41 and the rack 42 cooperate to cause the moving coil 22 to be in the lowest position, thereby keeping the sealing ring 23 in the first state; when the handle 50 is rotated to the operating position, the gear 41 drives the rack 42 to move upward, causing the moving coil 22 to move to the highest position, thereby switching the sealing ring 23 to the second state.

[0078] See also Figures 7 to 10 , this embodiment and Figures 1 to 6 The similarities between the embodiments shown are not described in detail here, and only the differences between the embodiments and Figures 1 to 6 The difference between the embodiment shown in the figure is described as follows: the driving mechanism 40 includes a cam arranged on the rotating shaft 55, the cam cooperates with the moving coil 22, and an elastic member 24 is arranged between the fixing member 21 and the moving coil 22. In this way, by operating the handle 50 to control the cam to rotate in different directions, the moving coil 22 can be urged to move upward or downward, thereby switching the sealing ring 23 between the first state and the second state.

[0079] The elastic member 24 includes any one of the following: a spring, an elastic rubber ring, a metal spring, but is not limited thereto. In the illustrated embodiment, the elastic member 24 is a spring.

[0080] The driving mechanism 40 includes a cam portion 41. When the handle 50 is in the folded position, the cam portion 41 presses against the moving coil 22, causing the sealing ring 23 to remain in the first state. When the handle 50 is rotated to the operating position, the cam portion 41 no longer presses against the moving coil 22, and the moving coil 22 moves upward under the action of the elastic member 24, causing the sealing ring 23 to switch to the second state.

[0081] The fixing member 21 is provided with an annular step portion 212, the moving coil 22 is provided with a matching portion 222 opposite to the step portion 212, the elastic member 24 is cylindrical, and the two ends of the elastic member 24 are respectively in contact with or connected to the step portion 212 and the matching portion 222. In this way, the elastic member 24 can exert an elastic force on the moving coil 22 to cause the moving coil 22 to move upward. The first body portion 217 of the fixing member 21 also includes a limiting wall 216 located on one side of the step portion 212, and the matching portion 222 is further provided with a limiting portion 226 downward to limit the elastic member 24 to prevent the elastic member 24 from tilting.

[0082] Please continue reading Figures 1 to 6 The cup cover assembly 100 further includes an ear button 60 rotatably mounted on the cup cover 10. A locking portion 81 cooperating with the ear button 60 is protruded outwardly from the top of the mixing cup 80. When in use, the cup cover assembly 100 does not need to be rotated, but only needs to be rotated to make the ear button 60 and the locking portion 81 buckle together, thereby limiting the cup cover assembly 100 to the mixing cup 80, which is more convenient to operate. Similarly, when the cup cover assembly 100 needs to be removed, the ear button 60 only needs to be rotated in the opposite direction to release the ear button 60 and the locking portion 81, and the cup cover assembly 100 can be removed from the mixing cup 80.
