Description

TECHNICAL FIELD

[0001] The utility model belongs to cup cover technical field, especially relate to a guide structure of cover subassembly. BACKGROUND

[0002] When driving a car, a special cup is usually equipped on the car to facilitate the driver to drink. This special cup is often called a car cup. Since the driver needs to drive the car, he can only operate the car cup with one hand.

[0003] The earliest car cup is directly open to facilitate the driver to operate. The driver can directly drink the water in the cup. However, the dust inside the car can easily fall into the cup through the opening, causing the water in the cup to mix with the dust. To solve the dust problem, the car cup has been innovated in design and introduced a dust cover to improve the hygiene of use. After introducing the dust cover, how to conveniently open and close with one hand has become the design focus of the car cup. Among them, the slide cover type cup cover that uses a sliding mechanism to realize opening and closing is widely welcomed due to its convenience for one-handed operation.

[0004] For example, patent US10124942B2 provides a cover assembly that can be used on a car cup. Specifically, a first opening (through which the driver drinks the liquid in the cup) is provided on the cover body, a sliding block is slidably arranged on the cover body, a first positioning magnet is provided on the sliding block, and a second positioning magnet and a third positioning magnet are provided on the cover body. When the sliding block is slid to a position where the first positioning magnet and the second positioning magnet are attracted to each other, the sliding block is kept in the closed position under the action of the magnetic force. When the sliding block is in the closed position, it covers the first opening, so that the liquid in the cup will not flow out of the first opening. When the sliding block is slid to a position where the first positioning magnet and the third positioning magnet are attracted to each other, the sliding block is kept in the open position under the action of the magnetic force. At this time, the sliding block does not cover the first opening, and the first opening is exposed, so that the driver can drink the liquid in the cup through the first opening.

[0005] For example, patent CN217565584U provides a resilient opening and closing cup cover that can be used on a car cup. A sliding groove is provided on the cover body, one end of the sliding groove is provided with a drinking opening, and a sliding cover is slidably arranged in the sliding groove. A closing positioning groove and an opening positioning groove are sequentially provided on the side wall of the sliding groove, and a resilient wall is protrudingly provided on one side of the sliding cover. When the sliding cover is slid to a position where the resilient arm is arranged in the closing positioning groove, the sliding cover covers the drinking opening so that the liquid in the cup will not flow out of the drinking opening. When the sliding cover is slid to a position where the resilient arm is in the opening positioning groove, the sliding cover does not cover the drinking opening, and the drinking opening is exposed, so that the driver can drink the liquid in the cup through the drinking opening.

[0006] The two cup covers described above can be held by the driver when in use, and the driver can push the sliding cover with his fingers to perform opening or closing operation, which is simple and convenient to operate.

[0007] However, over time, more and more people began to use the car cup in the car into daily life - such as for outdoor, garage, office, etc., so that it becomes a convenient and practical life supplies. The continuous expansion of the use of car cup, prompting users to its function put forward higher, more diverse needs.

[0008] When the car cup is used in daily life rather than placed in the car cup holder in the car, the car cup is knocked down more and more frequently. How to ensure that the liquid in the cup does not spill when the car cup is knocked down has become a new design requirement and innovation direction. Utility model content

Detailed Implementation

[0038] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0039] To keep the drawings concise, only the parts relevant to this invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0040] See Figures 1 to 14 This embodiment provides a guide structure for a cover assembly, including a cover body 1, a sliding cover 2, and an elastic sealing element 3. The cover body 1 has a sliding groove 7, and a drinking port 4 is provided on the bottom surface 8 of the sliding groove 7. The drinking port 4 is a through hole connecting a first side and a second side of the cover body 1. The sliding groove 7 is located on the first side of the cover body 1. The sliding cover 2 is slidably disposed in the sliding groove 7, and the sliding cover 2 is configured to slide between a closed position and an open position on the cover body 1.

[0041] The elastic seal 3 is provided on the sliding cover 2. When the sliding cover 2 slides, it drives the elastic seal 3 to move. When the sliding cover 2 is in the closed position, the sliding cover 2 covers the drinking mouth 4 and the elastic seal 3 covers the drinking mouth 4. When the sliding cover 2 is in the open position, both the sliding cover 2 and the elastic seal 3 leave the drinking mouth 4, and at the same time, the air hole 31 on the cover body 1 is in the air-ventilated state.

[0042] A guide assembly is provided between at least one side of the sliding cover 2 and the side wall of the sliding groove 7. The guide assembly includes a guide groove 16 and a guide protrusion 17. Either the guide groove 16 or the guide protrusion 17 is provided on the side wall of the sliding groove 16, and the other is provided on the side wall of the sliding cover 2. During the stroke of the sliding cover 2 from the open position to the closed position, the guide protrusion 17 is slidably connected in the guide groove 16 for at least part of the stroke.

[0043] The sliding direction of the sliding cover 2 during the process of sliding from the open position to the closed position is the first direction, and the sliding direction of the sliding cover 2 during the process of sliding from the closed position to the open position is the second direction. The guide groove 16 is offset towards the second side of the cover body 1 in the first direction.

[0044] In the process of sliding to the closed position, the sliding cover 2 will press the elastic sealing member 3 against the cover body 1 under the action of the guide assembly due to the guide groove 16 being offset to the second side of the cover body 1 in the first direction, thereby sealing the drinking opening 4, so that the container with the guide structure of the cover assembly of the embodiment will not leak the content in the container in the pouring state.

[0045] For the convenience of description, the combination of the cover body 1, the sliding cover 2 and the elastic sealing member 3 is referred to as a cover assembly. The cover assembly is generally used in cooperation with a containing member. The cover body 1 in the cover assembly is threadedly connected or coveringly connected to the opening of the containing member to form a container (in addition to the cover assembly and the containing member, other components can be added according to actual needs). For example, the containing member can be a cup body or a bottle body, and the cover assembly is connected to the cup opening of the cup body or the bottle opening of the bottle body to form a cup or a bottle with a cover. The content in the containing member can be taken out from the drinking opening 4 of the cover body 1.

[0046] When the user needs to pour out the content (for example, the content is water, and the user needs to drink water), the sliding cover 2 on the cover body 1 can be slid to the open position, and the user can pour out the content from the drinking opening 4. When the user does not need to pour out the content (for example, the user does not need to drink water), the sliding cover 2 can be slid to the closed position. In this state, the sliding cover 2 covers the drinking opening of the cover body 1, the elastic sealing member 3 covers the drinking opening, the sliding cover 2 presses the elastic sealing member 3 at the drinking opening, thereby sealing the drinking opening, so that the container will not leak the content from the drinking opening 4 in the pouring state. It should be noted that although the container is usually used to contain liquids such as drinking water, it can also be used to contain solid particles, and the type of content in the container is not limited.

[0047] The guide structure of the cover assembly of the embodiment will be further described below.

[0048] As shown in Figure 2 , when the cover body 1 is placed on a horizontal plane, the upper side of the cover body 1 is the first side of the cover body 1, the lower side of the cover body 1 is the second side of the cover body 1, the upward direction is the first side direction of the cover body 1, and the downward direction is the second side direction of the cover body 1.

[0049] The magnetic detachable connection between the sliding cover 2 and the cover body 1 can be, as indicated in Figure 14 , that a first magnet 5 is arranged on the sliding cover 2, and a second magnet 6 is arranged on the cover body 1, the first magnet 5 and the second magnet 6 are attracted to each other, thereby attracting the sliding cover 2 to the cover body 1.

[0050] When the sliding cover 2 is in the closed position, the sliding cover 2 presses the elastic sealing member 3 against the cover body 1 at the drinking opening 4, and the sliding cover 2 presses the elastic sealing member 3 tightly (and needs the elastic sealing member 3 to produce elastic deformation), so as to realize that the elastic sealing member 3 seals the drinking opening 4. In the embodiment, the way to make the sliding cover 2 press the elastic sealing member 3 against the cover body 1 at the drinking opening 4 when the sliding cover 2 is in the closed position is to set a guiding and pressing structure to make the sliding cover 2 press the elastic sealing member 3 against the cover body 1 at the drinking opening 4 when the sliding cover 2 is in the closed position.

[0051] Specifically, the guiding and pressing structure can guide the part of the sliding cover 2 provided with the elastic sealing member 3 to move towards the second side of the cover body 1 during the sliding of the sliding cover 2 to the closed position, so that the sliding cover 2 can press the elastic sealing member 3 against the cover body 1 when the sliding cover 2 is in the closed position, and then realize the sealing of the drinking opening 4 by the elastic sealing member 3. The guiding assembly mentioned above is one of the guiding and pressing structures.

[0052] For the convenience of description, the stroke of the sliding cover 2 from the open position to the closed position is referred to as the first stroke, and the stroke of the sliding cover 2 sliding to the closed position under the guidance of the guiding and pressing structure is referred to as the second stroke. The second stroke is equal to the first stroke or is a part of the first stroke. Preferably, the second stroke is a part of the first stroke and is located at the end of the first stroke.

[0053] The guiding and pressing structure comprises at least one guiding and pressing assembly, and the guiding and pressing assembly comprises a first guiding part and a second guiding part. The first guiding part is arranged on the cover body 1, and the second guiding part is arranged on the sliding cover 2 and moves synchronously with the sliding cover 2. In the second stroke, the first guiding part and the second guiding part are in sliding connection, and the second guiding part is located in the direction of the first guiding part towards the second side of the cover body 1. The first guiding part and the second guiding part are configured to move the second guiding part towards the second side of the cover body 1 when the second guiding part slides under the limitation of the first guiding part in the second stroke.

[0054] Specifically, at least one of the first guiding part and the second guiding part is a guiding surface. When the first guiding part is a guiding surface, the first guiding part is a guiding surface arranged towards the second side of the cover body 1. When the second guiding part is a guiding surface, the second guiding part is a guiding surface arranged towards the first side of the cover body 1. The guiding surface is offset towards the second side of the cover body 1 in the first direction. Specifically, the offset manner can be offset in the form of a plane (i.e. an inclined plane), or offset in the form of a curved surface (i.e. the curved surface is closer to the second side of the cover body 1 as it goes in the first direction), or offset in the form of a combination of a plane and a curved surface, etc., and the specific manner is not limited.

[0055] When the first guide portion on the cover body 1 is a guide surface, in the second stroke, the second guide portion moves along the guide surface as the sliding cover 2 slides in the first direction, and gradually moves to the second side of the cover body 1 as the guide surface is offset to the second side of the cover body 1 in the first direction, thereby moving the sliding cover 2 to the second side of the cover body 1.

[0056] When the second guide portion on the sliding cover 2 is a guide surface, in the second stroke, the guide surface slides against the first guide portion as the sliding cover 2 slides in the first direction, and gradually moves to the second side of the cover body 1 as the guide surface is offset to the second side of the cover body 1 in the first direction, thereby moving the sliding cover 2 to the second side of the cover body 1.

[0057] When the first guide portion on the cover body 1 and the second guide portion on the sliding cover 2 are both guide surfaces, in the second stroke, the second guide portion slides along the first guide portion as the sliding cover 2 slides in the first direction, and gradually moves to the second side of the cover body 1 as the sliding cover 2 slides in the first direction, thereby moving the sliding cover 2 to the second side of the cover body 1.

[0058] In the second stroke, the part of the sliding cover 2 provided with the elastic sealing member 3 moves a distance smaller than the distance by which the elastic sealing member 3 protrudes from the sliding cover 2 in a direction perpendicular to the groove bottom surface 8 of the sliding groove 7, so that the sliding cover 2 can press the elastic sealing member 3 against the drinking opening 4 of the cover body 1 and deform the elastic sealing member 3 when the sliding cover 2 is in the closed position, thereby closing the drinking opening 4. The distance by which the elastic sealing member 3 protrudes from the sliding cover 2 is small, so the part of the sliding cover 2 provided with the elastic sealing member 3 moves a distance smaller than 5 mm, preferably about 0.6 mm, in a direction perpendicular to the groove bottom surface 8 of the sliding groove 7 in the second stroke; of course, the distance by which the part of the sliding cover 2 provided with the elastic sealing member 3 moves in a direction perpendicular to the groove bottom surface 8 of the sliding groove 7 in the second stroke can also be adjusted according to actual conditions.

[0059] The sliding cover 2 slides a small distance from the open position to the closed position, so the part of the sliding cover 2 provided with the elastic sealing member 3 moves a small distance in a plane parallel to the groove bottom surface 8 of the sliding groove 7 in the second stroke, which is generally selected to be within 10 mm, preferably about 2 mm.

[0060] Thus, the arrangement of the wire pressing structure does not affect the user's feeling during the pushing of the sliding cover 2.

[0061] Specifically, at least one side wall of the sliding groove 7 is sequentially provided with a closing positioning groove 9 and an opening positioning groove 10, and at least one side of the sliding cover 2 is provided with an elastic arm 11. When the elastic arm 11 is located in the closing positioning groove 9, the sliding cover 2 is in the closing position, and when the elastic arm 11 is located in the opening positioning groove 10, the sliding cover 2 is in the opening position. In this embodiment, preferably, both side walls of the sliding groove 7 are sequentially provided with the closing positioning groove 9 and the opening positioning groove 10, and both sides of the sliding cover 2 are provided with the elastic arm 11. More preferably, the elastic arms 11 on both sides of the sliding cover 2 are symmetrically arranged, and the closing positioning grooves 9 and the opening positioning grooves 10 on the side walls of the sliding groove 7 are also symmetrically arranged.

[0062] As shown in Figure 7 the elastic arm 11 is connected with a connecting arm 12 at both ends in the sliding direction of the sliding cover 2. The other end of the connecting arm 12, which is not connected with the elastic arm 11, is connected with the sliding cover 2, that is, both ends of the elastic arm 11 are connected with the sliding cover 2 through the connecting arms 12. The elastic arm 11 and the connecting arm 12 have a gap 13 between the side wall of the sliding cover 2. The gap 13 is used for the elastic deformation of the elastic arm 11 and the connecting arm 12. When the sliding cover 2 slides between the closing position and the opening position, the elastic arm 11 elastically deforms towards the gap 13, so that the elastic arm 11 can slide out of the closing positioning groove 9 or the opening positioning groove 10 and slide in the non-closing positioning groove area and the non-opening positioning groove area on the side wall of the sliding groove 7.

[0063] Among them, the part of the inner side wall of the sliding groove 7 located on both sides in the sliding direction of the sliding cover 2 is a sliding inner side wall 14, and the closing positioning groove 9 and the opening positioning groove 10 are arranged in the sliding inner side wall 14. The part of the outer side wall of the sliding cover 2 located on both sides in the sliding direction of the sliding cover 2 is a sliding outer side wall 15.

[0064] The guiding and pressing structure in this embodiment includes the above-mentioned guiding assembly, fixing assembly and anti-disengagement assembly. The guiding assembly plays a main guiding and pressing role (the guiding and pressing role is the role of moving the sliding cover 2 to the second side of the cover body 1 in the second stroke). The second stroke refers to the stroke of the sliding cover 2 sliding under the limitation of the guiding assembly during the process of sliding from the opening position to the closing position.

[0065] In the guiding assembly, the guiding protrusion 17 is slidingly connected in the guiding groove 16 in the second stroke.

[0066] Specifically, in the embodiment, the two sliding inner side walls 14 of the sliding groove 7 are respectively provided with a guide assembly in cooperation with the corresponding sliding outer side wall 15. Moreover, when the sliding cover 2 is in the closed position, there is a guide assembly on each side of the first direction of the drinking opening 4. Thus, when the sliding cover 2 is in the closed position, the guide assemblies on both sides of the drinking opening 4 can well exert force on the sliding cover 2, so that the sliding cover 2 presses the elastic sealing member 3 at the drinking opening 4, so that the elastic sealing member 3 seals the drinking opening 4, preventing the contents in the container from flowing out. Among them, in the guide assembly, the inner side wall of the guide groove 16 on the sliding cover 2 close to the second side of the cover body 1 (that is, the inner side wall of the guide groove 16 facing the first side of the cover body 1, the inner side wall of the guide groove 16 on the second side of the cover body 1 in the direction of the guide protrusion 17) is the above-mentioned guide surface.

[0067] The end of the guide groove 16 in the first direction can be provided with an opening, and the opening is used for the guide protrusion 17 to slide into the guide groove 16 from the opening during the sliding of the sliding cover 2 in the first direction.

[0068] The drinking opening 4 is arranged on the groove bottom surface 8 of the sliding groove 7 close to the end of the groove bottom surface 8 in the first direction. At least one fixing assembly is arranged between the side walls of the sliding groove 7 at the end of the sliding cover 2 in the first direction, and the fixing assembly includes a clamping groove 20 and a clamping block 21. Either one of the clamping groove 20 and the clamping block 21 is arranged at the end of the sliding cover 2, and the other one is arranged at the side wall of the sliding groove 7. When the sliding cover 2 is in the closed position, the clamping block 21 is inserted into the clamping groove 20.

[0069] Specifically, the portions of the inner side walls of the sliding groove 7 located at both ends of the sliding direction of the sliding cover 2 are end inner side walls, and the drinking opening 4 is arranged on the groove bottom surface 8 of the sliding groove 7 close to one of the end inner side walls, which is a specific end inner side wall 18. The portions of the outer side walls of the sliding cover 2 located at both ends of the sliding direction of the sliding cover 2 are end outer side walls, and the end outer side wall facing the specific end inner side wall 18 is a specific end outer side wall 19.

[0070] The fixing assembly is arranged between the specific end inner side wall 18 and the specific end outer side wall 19, and either one of the clamping groove 20 and the clamping block 21 is arranged on the specific end inner side wall 18, and the other one is arranged on the specific end outer side wall 19. During the sliding of the sliding cover 2 from the open position to the closed position, the clamping block 21 is inserted into the clamping groove 20. Moreover, the clamping block 21 and the clamping groove 20 are configured to, during the insertion of the clamping block 21 into the clamping groove 20, the clamping block 21 / clamping groove 20 arranged on the specific end outer side wall 19 moves in the direction of the second side of the cover body 1 under the limitation of the clamping groove 20 / clamping block 21 arranged on the specific end inner side wall 18.

[0071] More specifically, in the present embodiment, the clamping groove 20 is arranged on the side wall of the sliding groove 7, and the clamping block 21 is arranged on the end of the sliding cover 2. In the fixing assembly, the inner wall surface of the clamping groove 20 facing the second side of the cover body 1 is the guiding surface, and the outer surface of the clamping block 21 facing the first side of the cover body 1 is the guiding surface.

[0072] The arrangement of the fixing assembly can not only provide the guiding and pressing function in the second stroke of the sliding cover 2, but also can play a fixing role. When the sliding cover 2 is in the closed position, the fixing assembly fixes the end of the sliding cover 2 (specifically, the end corresponding to the drinking opening 4). For example, when the content is hot water, hot gas is easy to push the elastic sealing member 3 away from the end of the sliding cover 2 through the drinking opening 4, thereby breaking the seal and causing leakage. The arrangement of the fixing assembly between the specific end outer wall 19 of the sliding cover 2 and the specific end inner wall 18 of the cover body 1 can effectively prevent such leakage.

[0073] The anti-disengagement assembly includes a clamping member 22 protruding from the groove bottom surface 8 of the sliding groove 7 and a clamping block 23 arranged on the sliding cover 2. The clamping member 22 protrudes from the groove bottom surface 8 to the first side of the cover body 1 by a certain distance and then bends to the second direction, so that the clamping member 22 and the groove bottom surface 8 cooperate to form a clamping groove facing the second direction. In the process of sliding the sliding cover 2 from the open position to the closed position, the clamping block 23 extends into the clamping groove; and the clamping block 23 and the clamping groove are configured such that, in the process of the clamping block 23 extending into the clamping groove, the clamping block 23 moves to the second side of the cover body 1 under the limitation of the inner side wall of the clamping groove facing the second side of the cover body 1. In the anti-disengagement assembly, the inner wall surface of the clamping groove facing the second side of the cover body 1 is the guiding surface, and the outer surface of the clamping block 23 facing the first side of the cover body 1 is the guiding surface.

[0074] As shown in Figure 12 The clamping block 23 can be arranged at the connection between the connecting arm 12 and the sliding cover 2. The clamping member 22 can protrude from the groove bottom surface 8 and extend into the gap 13, that is, the clamping member 22 is arranged in the gap 13. Preferably, two anti-disengagement assemblies can be arranged between the cover body 1 and the sliding cover 2, and two clamping members 22 can be arranged on the groove bottom surface 8 of the sliding groove 7.

[0075] The arrangement of the anti-disengagement assembly can not only provide the guiding and pressing function in the second stroke of the sliding cover 2, but also can play an anti-disengagement role. When the container with the cover assembly is dropped from a high place (for example, the user accidentally collides with the container in his hand, causing the container to fall out of his hand, or the container is placed on a table and then falls off the table after being collided), the arrangement of the anti-disengagement assembly can effectively prevent the sliding cover 2 from disengaging from the cover body 1. If the sliding cover 2 disengages from the cover body 1, it is easy to be lost because it cannot be found.

[0076] The slide cover 2 and the cover body 1 are assembled together, and a user can replace one of them at will, for example, when one of them is damaged, the damaged one is replaced, and for another example, the slide cover 2 can be lost sometimes (the cover body 1 is connected to a container and is large in size, and is not easy to be lost in comparison), and needs to be replaced. In order to facilitate the user to assemble the slide cover 2 and the cover body 1, the slide cover 2 can be designed as a central symmetric structure, so that the user does not need to distinguish the two ends of the slide cover 2 in the sliding direction when installing the slide cover 2, and the user is facilitated to install. The slide cover 2 is of a central symmetric structure, and the guide groove 16, the clamping block 21, the clamping block 23, the elastic sealing member 3 and the like on the slide cover 2 need to be centrally symmetrically arranged.

[0077] Although the slide cover 2 presses the elastic sealing member 3 against the cover body 1 when in the closed position, if the slide cover 2 presses the elastic sealing member 3 against the cover body 1 throughout the sliding process of the slide cover 2, a lot of frictional resistance will be increased, and the hand feeling of the user will be affected. Therefore, the embodiment is further provided with a lifting structure, which is arranged between the cover body 1 and the slide cover 2, and is used to guide the slide cover 2 to move to the first side direction of the cover body 1 during the process that the slide cover 2 slides away from the closed position, so that the slide cover 2 relaxes the pressing of the elastic sealing member 3. Preferably, in the direction perpendicular to the groove bottom surface 8 of the sliding groove 7, the distance that the slide cover 2 moves under the action of the lifting structure during the process that the slide cover 2 moves away from the closed position is greater than the distance that the elastic sealing member 3 protrudes from the slide cover 2, so that after the slide cover 2 moves away from the closed position, the elastic sealing member 3 does not contact the groove bottom surface 8 of the sliding groove 7, and the sliding frictional resistance of the slide cover 2 in the sliding groove 7 is reduced.

[0078] In order to facilitate the description, the stroke of the slide cover 2 from the closed position to the open position is referred to as a third stroke, and the stroke of the slide cover 2 moving to the first side direction of the cover body 1 relative to the cover body 1 in the guidance of the lifting structure is referred to as a fourth stroke. The fourth stroke is a part of the third stroke, and is located at the first end of the third stroke.

[0079] The lifting structure comprises at least one lifting assembly, and the lifting assembly comprises a lifting protrusion 24 and a corresponding groove 25. Any one of the lifting protrusion 24 and the groove 25 is arranged on the surface of the slide cover 2 facing the cover body 1, and the other one is arranged on the surface of the cover body 1 facing the slide cover 2. When the slide cover 2 is in the closed position, the lifting protrusion 24 is located in the groove 25, and when the slide cover 2 slides away from the closed position, the lifting protrusion 24 moves away from the groove 25 to make the slide cover 2 move to the first side direction of the cover body 1 relative to the cover body 1. Further, the groove 25 is correspondingly provided with a sliding groove 26, one end of the sliding groove 26 communicates with the groove 25; when the slide cover 2 slides on the cover body 1, the lifting protrusion 24 slides in the sliding groove 26, and when the slide cover 2 slides to the closed position, the lifting protrusion 24 slides to the groove 25. The arrangement of the sliding groove 26 can guide the movement of the lifting protrusion 24.

[0080] Specifically in the embodiment, the lifting protrusion 24 is arranged on the cover 2, the groove 25 and the sliding groove 26 are arranged on the groove bottom surface 8 of the sliding groove 7; four lifting assemblies are arranged in the cover assembly, two lifting assemblies arranged in a direction perpendicular to the first direction form a group, and two groups of lifting assemblies are arranged along the first direction.

[0081] In the second stroke, the area in which the cover 2 slides in the sliding groove 7 is the same as the area in which the cover 2 slides in the sliding groove 7 in the fourth stroke, and the sliding direction of the cover 2 in the second stroke is opposite to the sliding direction of the cover 2 in the fourth stroke.

[0082] The elastic sealing member 3 includes a first sealing part 27, which is arranged on the side of the cover 2 facing the cover body 1. When the cover 2 is in the closed position, the first sealing part 27 covers the drinking opening 4, and the first sealing part 27 extends to the surrounding part of the drinking opening 4 in the groove bottom surface 8 of the sliding groove 7. In this way, when the cover 2 presses the elastic sealing member 3 against the groove bottom surface 8 of the sliding groove 7, the elastic sealing member 3 can seal the drinking opening 4. However, this sealing method has poor sealing performance. Therefore, in the embodiment, the elastic sealing member 3 is further improved, and the elastic sealing member 3 further includes a second sealing part 28.

[0083] As shown in Figure 10 the second sealing part 28 is annular and protrudes from the side of the first sealing part 27 facing the groove bottom surface 8 of the sliding groove 7; when the cover 2 is in the closed position, the drinking opening 4 is located inside the annular structure of the second sealing part 28. Preferably, the elastic sealing member 3 can include multiple layers of second sealing parts 28, and the annular structures of the multiple layers of second sealing parts 28 are sequentially sleeved to improve the sealing effect.

[0084] Further, the first sealing part 27 extends away from the cover body 1 through the channel on the cover 2 and extends to the surface on the side of the cover 2 away from the cover body 1, and the size of the member formed by the first sealing part 27 on the surface on the side of the cover 2 away from the cover body 1 is greater than the channel on the cover 2. The member can be used as an anti-slip strip 30 when the user pushes the cover 2. In addition to being able to prevent slipping, the anti-slip strip 30 can also prevent the first sealing part 27 from being detached from the cover 2. Preferably, the first sealing part 27 can form multiple anti-slip strips 30 through multiple channels on the cover 2, respectively.

[0085] The air hole 31 can be arranged on the bottom surface 8 of the sliding groove 7 to communicate the first side and the second side of the cover body 1, the air passage 32 corresponding to the air hole 31 is arranged on the surface of the sliding cover 2 facing the bottom surface 8 of the sliding groove 7, and the air hole sealing piece corresponding to the air hole 31 is arranged on the sliding cover 2. When the sliding cover 2 is in the closed position, the air hole sealing piece seals the air hole 31; when the sliding cover 2 is in the open position, the air hole sealing piece is away from the air hole 31, the air hole 31 is communicated with the air passage 32, and the container can be communicated with the outside through the air hole 31 and the air passage 32 in addition to the drinking opening 4.

[0086] Specifically in the embodiment, the air hole sealing piece can be a third sealing part 29 protruding on the first sealing part 27, the third sealing part 29 is arranged on the first sealing part 27 in the direction of the bottom surface 8 of the sliding groove 7, and the third sealing part 29 has a ring structure. At this time, the third sealing part 29 is part of the elastic sealing piece 3, and the air hole sealing piece is part of the elastic sealing piece 3. Preferably, the third sealing part 29 can also be arranged in multiple layers, and the ring structures of the multiple layers of the third sealing part 29 are sequentially sleeved, so as to improve the sealing effect.

[0087] The sliding cover 2 has a central symmetry structure, and the sliding cover 2 is provided with two elastic sealing pieces 3. When the sliding cover 2 is in the closed position, the drinking opening 4 is located in the ring structure of the second sealing part 28 of one of the elastic sealing pieces 3, and the air hole 31 is located in the ring structure of the corresponding third sealing part 29 of the other elastic sealing piece 3. In this way, when the sliding cover 2 is in the closed position, the two elastic sealing pieces 3 seal the drinking opening 4 and the air hole 31, respectively.

[0088] Preferably, the entire elastic sealing piece 3 is integrally made, and the elastic sealing piece 3 is made of silica gel or rubber.

[0089] Of course, in other embodiments, the elastic sealing piece 3 and the air hole sealing piece can also adopt other structures, for example, in the embodiment in which the elastic sealing piece 3 is only provided with the first sealing part 27 (without the second sealing part 28), the part of the elastic sealing piece 3 after the central symmetry can be used as the air hole sealing piece.

[0090] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments. Even if various changes are made to the utility model, as long as the changes belong to the scope of the utility model claims and equivalent technologies, they still fall within the protection scope of the utility model.
