Cup cover and water cup

Abstract

The utility model discloses a cup cover and a water cup, and belongs to the technical field of articles of daily use. The cup cover comprises a first cup cover body, a second cup cover body and a locking assembly. At least one part of the locking assembly can penetrate through the first opening and is exposed out of the containing space of the first cup cover, so that a user can directly contact the locking assembly and operate the locking assembly. When the cup cover needs to be opened, a user only needs to apply axial pressing force along the first cup cover to the exposed locking assembly of the first opening, so that a second clamping part in the locking assembly and a first clamping part in the second cup cover are separated from each other in a clamping state, and the first cup cover can rotate in the direction far away from the second cup cover relative to the second cup cover. Thus, after the cup cover is installed on the cup body of the water cup, the water cup can be opened or closed by rotating the cup cover, and the water cup can be opened or closed by controlling the first cup cover body and the second cup cover body in the cup cover to rotate relatively.

[0055] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0056] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a cup cover provided by an embodiment of the present application. The cup cover 000 may include: a first cup cover 100, a second cup cover 200, and a locking component 300.

[0057] Please refer to Figure 2 and Figure 3 , Figure 2 which is a schematic partial structural diagram of a first cup cover provided by an embodiment of the present application, Figure 31 is a partial structural diagram of a first cup cover provided by an embodiment of the present application from another perspective. The first cup cover 100 in the cup cover 000 is located on one side of the second cup cover 200 and is rotatably connected to the second cup cover 200. The first cup cover 100 has a receiving space C and a first opening 101 connected to the receiving space C. The first opening 101 in the first cup cover 100 can be located on the side of the first cup cover 100 away from the second cup cover 200.

[0058] In the present application, the side of the second cup cover 200 in the cup cover 000 that faces away from the first cup cover 100 is used to connect with the cup body of the water cup. In this case, one side of the second cup cover 200 can be rotatably connected with the first cup cover 100, and the other side can be firmly engaged with the cup body, so as to ensure the firm fixation between the cup cover 000 and the cup body. That is, the cup cover 000 can be connected with the cup body through the second cup cover 200.

[0059] In the examples of this application, please refer to Figure 4 , Figure 4 2 is a schematic diagram of a second cup cover structure provided in an embodiment of the present application. The second cup cover 200 in the cup cover 000 has a first clamping portion 201 .

[0060] For example, please refer to Figures 5 to 7 , Figure 5 is a schematic diagram of a second cup cover and a locking assembly combination provided in an embodiment of the present application, Figure 6 is a schematic diagram of a driving member structure provided in an embodiment of the present application, Figure 7 1 is a schematic diagram of a clamping member structure provided in an embodiment of the present application. At least part of the locking assembly 300 in the cup cover 000 is located in the accommodation space C in the first cup cover 100. Part of the locking assembly 300 can be exposed through the first opening 101, and the locking assembly 300 has a second clamping portion 3021 that cooperates with the first clamping portion 201 in the second cup cover 200.

[0061] In this case, at least a portion of the locking assembly 300 can pass through the first opening 101 and be exposed outside the accommodating space C of the first cup cover 100, so that the user can directly contact and operate the locking assembly 300. At the same time, the second clamping portion 3021 in the locking assembly 300 can match and tightly combine with the first clamping portion 201 on the second cup cover 200. In this way, after the first clamping portion 201 is clamped with the second clamping portion 3021, the first cup cover 100 and the second cup cover 200 can be tightly locked by the first clamping portion 201 and the second clamping portion 3021 to form a reliable connection.

[0062] After the first cup lid 100 is snapped onto the second cup lid 200, the first engaging portion 201 and the second engaging portion 3021 are engaged; after the locking assembly 300 is pressed axially along the first cup lid 100, the second engaging portion 3021 can move in a direction away from the first engaging portion 201 to separate the first engaging portion 201 from the second engaging portion 3021.

[0063] In this case, the user only needs to apply an axial pressing force along the first cup lid 100 to the locking assembly 300 exposed at the first opening 101, so that the second engaging portion 3021 in the locking assembly 300 disengages from the first engaging portion 201 in the second cup lid 200, thereby releasing the snap connection state between the first cup lid 100 and the second cup lid 200, ensuring that the first cup lid 100 can rotate away from the second cup lid 200 relative to the second cup lid 200. This not only simplifies the operation process of opening the cup lid 000, improves the user experience, but also ensures the connection strength of the cup lid 000 in the closed state, effectively preventing liquid leakage.

[0064] In summary, the present application proposes a cup lid, including a first cup lid, a second cup lid and a locking assembly. Since at least a part of the locking assembly can pass through the first opening and be exposed outside the accommodating space of the first cup lid, the user can directly access and operate the locking assembly. At the same time, the second engaging portion in the locking assembly can match and tightly combine with the first engaging portion on the second cup lid. In this way, after the first engaging portion and the second engaging portion are engaged, the first cup lid and the second cup lid can be tightly locked through the first engaging portion and the second engaging portion to form a reliable connection. When the cup lid needs to be opened, the user only needs to apply an axial pressing force along the first cup lid to the locking assembly exposed at the first opening, so that the second engaging portion in the locking assembly disengages from the first engaging portion in the second cup lid, thereby releasing the snap connection state between the first cup lid and the second cup lid, ensuring that the first cup lid can rotate away from the second cup lid relative to the second cup lid. This not only simplifies the operation process of opening the cup lid, improves the user experience, but also ensures the connection strength of the cup lid in the closed state, effectively preventing liquid leakage. In this way, after installing this cup lid on the cup body of the water cup, not only can the water cup be opened or closed by rotating the cup lid, but also the water cup can be opened or closed by controlling the relative rotation of the first cup lid and the second cup lid in the cup lid.

[0065] In the embodiment of the present application, as Figures 5 to 7 shown, the locking assembly 300 may include: a driving member 301 and a engaging member 302 that cooperate with each other.

[0066] The driving member 301 in the locking assembly 300 can move axially relative to the first cup cover 100 along the axis of the first cup cover 100, and at least a part of the driving member 301 is exposed through the first opening 101.

[0067] The engaging member 302 in the locking assembly 300 can move radially relative to the first cup cover 100 along the radial direction of the first cup cover 100, and one end of the engaging member 302 facing away from the driving member 301 has a second engaging portion 3021 that cooperates with the first engaging portion 201.

[0068] In this case, the driving member 301 in the locking assembly 300 can move within the first opening 101 in the axial direction of the first cup cover 100, and at least a part of the driving member 301 can pass through the first opening 101 and be exposed outside the accommodation space C of the first cup cover 100, so that the user can directly contact and operate the driving member 301. At the same time, the engaging member 302 in the locking assembly 300 can move along the radial direction of the first cup cover 100, so that the second engaging portion 3021 on the side of the engaging member 302 away from the driving member 301 can accurately match and tightly engage with the first engaging portion 201 on the second cup cover 200. In this way, after the first engaging portion 201 and the second engaging portion 3021 are engaged, the first cup cover 100 and the second cup cover 200 can be tightly locked through the first engaging portion 201 and the second engaging portion 3021 to form a reliable connection.

[0069] Wherein, after the driving member 301 in the locking assembly 300 is subjected to an axial pressing force along the axis of the first cup cover 100, the driving member 301 can drive the engaging member 302 to move in a direction away from the driving member 301, so that the first engaging portion 201 and the second engaging portion 3021 are separated.

[0070] In this case, the user only needs to apply an axial pressing force along the axis of the first cup cover 100 to the driving member 301 exposed in the first opening 101, so that the driving member 301 moves in the axial direction of the first cup cover 100, and then acts on the engaging member 302 through mechanical transmission, so that the engaging member 302 moves away from the driving member 301 in a direction away from the driving member 301, so that the second engaging portion 3021 is disengaged from the first engaging portion 201, and then the engaging state of the first cup cover 100 and the second cup cover 200 is released, so as to ensure that the first cup cover 100 can rotate relative to the second cup cover 200 in a direction away from the second cup cover 200.

[0071] Optionally, as Figure 6As shown, the driving member 301 in the locking assembly 300 may include: a button portion 3011 and a first sliding portion 3012 connected axially to the first cup lid 100. At least a part of the first sliding portion 3012 is located within the accommodation space C in the first cup lid 100, at least a part of the button portion 3011 is located within the accommodation space C in the first cup lid 100, and the button portion 3011 can be exposed through the first opening 101 on the first cup lid 100. In a possible implementation, the entire first sliding portion 3012 is located within the accommodation space C in the first cup lid 100. That is, a part of the button portion 3011 can extend out of the accommodation space C through the first opening 101, so that the operator can directly apply a pressing action, and the control of the cup lid 000 can be achieved without complicated operations.

[0072] In the present application, as Figure 7 shown, the engaging member 302 in the locking assembly 300 includes: a second sliding portion 3022 and a second engaging portion 3021 connected radially to the first cup lid 100. At least a part of the second sliding portion 3022 is located within the accommodation space C in the first cup lid 100, and at least a part of the second engaging portion 3021 is located outside the accommodation space C in the first cup lid 100. In a possible implementation, the entire second sliding portion 3022 is located within the accommodation space C in the first cup lid 100, and the entire second engaging portion 3021 is located outside the accommodation space C in the first cup lid 100.

[0073] Among them, the first sliding portion 3012 in the driving member 301 cooperates with the second sliding portion 3022 in the engaging member 302. The first sliding portion 3012 is configured to: after receiving the pressing force applied by the button portion 3011 in the driving member 301, drive the second sliding portion 3022 to move in the radial direction of the first cup lid 100 along a direction away from the first sliding portion 3012.

[0074] In this way, the operator can directly press the button portion 3011 exposed through the first opening 101 in the first cup lid 100 without complicated operations, thereby generating a pressing force along the axial direction of the first cup lid 100 towards the second cup lid 200. After this pressing force acts on the first sliding portion 3012, it can drive the second sliding portion 3022 to slide in the radial direction of the first cup lid 100 along a direction away from the first sliding portion 3012, so that the entire engaging member 302 can slide in the radial direction of the first cup lid 100 along a direction away from the first sliding portion 3012. Furthermore, the second engaging portion 3021 in the engaging member 302 will move along a direction away from the first engaging portion 201 provided on the second cup lid 200 until the second engaging portion 3021 is separated from the first engaging portion 201.

[0075] Optionally, please refer to Figure 8 , Figure 8Yes Figure 1 Partial structural explosion diagram. The first cup lid 100 in the cup lid 000 has a rotating shaft A1, and the second cup lid 200 in the cup lid 000 may have a rotating shaft connecting member A2 connected to the rotating shaft A1. The rotating shaft A1 can be rotatably connected to the rotating shaft connecting member A2. Therefore, the first cup lid 100 and the second cup lid 200 in the cup lid 000 can be rotatably connected through the cooperation of the rotating shaft A1 and the rotating shaft connecting member A2.

[0076] Among them, a torsion spring A3 may also be provided between the rotating shaft A1 and the rotating shaft connecting member A2. The torsion spring A3 includes a torsion spring connecting portion A31 sleeved on the rotating shaft A1, and a first strut A32 and a second strut A33 located on both sides of the torsion spring connecting portion A31. The first strut A32 and the second strut A33 are respectively in contact with the first cup lid 100 and the second cup lid 200. After the first cup lid 100 and the second cup lid 200 are snapped together, the torsion spring A3 is in a compressed state and stores elastic potential energy. After the first engaging portion 201 and the second engaging portion 3021 are separated, the elastic potential energy stored in the torsion spring A3 can be quickly released, so that the first cup lid 100 can rotate around the second cup lid 200 in a direction away from the first cup lid 100, thereby realizing the opening and closing of the cup lid 000.

[0077] In the embodiment of the present application, as Figure 6 and 7 shown, the first sliding portion 3012 of the driving member 301 has a first inclined surface S1, and the second sliding portion 3022 of the engaging member 302 has a second inclined surface S2, wherein the first inclined surface S1 is in contact with the second inclined surface S2.

[0078] In this case, since the first sliding portion 3012 is designed with a first inclined surface S1, the second sliding portion 3022 is correspondingly provided with a second inclined surface S2, and the first inclined surface S1 is in contact with the second inclined surface S2. Therefore, when the first sliding portion 3012 is pressed in the direction towards the second cup lid 200, a component force along the radial direction of the first cup lid 100 will be generated on the contact surface between the first inclined surface S1 and the second inclined surface S2. This component force can cause the second sliding portion 3022 to slide along the radial direction of the first cup lid 100 away from the first sliding portion 3012. Thus, the first sliding portion 3012 and the second sliding portion 3022 realize the movement of the second sliding portion 3022 in the radial direction of the first cup lid 100 along the direction away from the first sliding portion 3012 through the relative movement between the first inclined surface S1 and the second inclined surface S2.

[0079] Exemplarily, as Figure 6 and 7As shown, the second inclined surface S2 on the second sliding portion 3022 has a guide plate N, and the first inclined surface S1 on the first sliding portion 3012 has a guide groove M that cooperates with the guide plate N. At least a part of the guide plate N is located within the guide groove M, and the plate surface of the guide plate N is parallel to the axial direction of the first cup cover 100 in the cup cover 000 and perpendicular to the second inclined surface S2. For example, the entire guide plate N is located within the guide groove M. It should be noted that in this application, the plate surface of the guide plate N being parallel to the axial direction of the first cup cover 100 in the cup cover 000 means that the plate surface of the guide plate N is generally parallel to the axial direction of the first cup cover 100 in the cup cover 000, that is, there may be a small included angle between the plate surface of the guide plate N and the axial direction of the first cup cover 100, such as 1°, 2°, and 3°; the plate surface of the guide plate N being perpendicular to the second inclined surface S2 means that the plate surface of the guide plate N is generally perpendicular to the second inclined surface S2, that is, the included angle between the plate surface of the guide plate N and the second inclined surface S2 can be 88°, 89°, and 91°.

[0080] In this case, the guide plate N on the second inclined surface S2 and the guide groove M on the first inclined surface S1 form a precise docking. In this way, not only is the close contact between the two inclined surfaces ensured, but also the guide plate N can be completely embedded in the guide groove M to improve the stability and directivity of the sliding mechanism, so that the sliding trajectory of the second sliding portion 3022 is precisely controlled during the sliding process, preventing unnecessary shaking and deviation, thereby greatly enhancing the smoothness of the locking and unlocking operations.

[0081] Optionally, please refer to Figure 6 and Figure 9 , Figure 9 is a schematic structural diagram of another first cup cover provided by an embodiment of the present application from another perspective. The driving member 301 further includes a guide plate 3013 connected to the key portion 3011. An auxiliary guiding member 107 is provided in the accommodating space C in the first cup cover 100. The auxiliary guiding member 107 can be arranged around the first opening 101 in the accommodating space C. The auxiliary guiding member 107 can have a guiding chute 1071, and the extending direction of the guiding chute 1071 is parallel to the axial direction of the first cup cover 100. Among them, at least a part of the guide plate 3013 can be located within the guiding chute 1071. In this way, through the cooperation between the guide plate 3013 and the guiding chute 1071, the key portion 3011 can only move along the axial direction of the first cup cover 100.

[0082] In a possible implementation manner, the key portion 3011, the first sliding portion 3012, and the guide plate 3013 can be an integrally formed structure.

[0083] In the embodiment of the present application, as Figure 9As shown, a baffle 102 is provided in the accommodation space C of the first cup lid 100, and the baffle 102 is located on the side of the second sliding portion 3022 in the engaging member 302 away from the first sliding portion 3012 in the driving member 301; the locking assembly 300 in the cup lid 000 further includes: an elastic element 303 located between the baffle 102 and the second sliding portion 3022, and two ends of the elastic element 303 are respectively abutted against the baffle 102 and the second sliding portion 3022. Exemplarily, the elastic element 303 can be a compression spring.

[0084] In the present application, after the pressing force is applied to the button portion 3011 in the driving member 301, the pressing force will be transmitted to the first sliding portion 3012, so that the first sliding portion 3012 can drive the second sliding portion 3022 in the engaging member 302 away from the first sliding portion 3012. During this process, the elastic element 303 installed between the baffle 102 and the second sliding portion 3022 is compressed due to the pressure on both ends and stores elastic potential energy. After the pressing force applied to the button portion 3011 is withdrawn, the elastic potential energy stored in the elastic element 303 can be released, so that the second sliding portion 3022 can be driven to return to its original position in the direction towards the first sliding portion 3012, and at the same time drive the button portion 3011 to rebound upward to the initial state.

[0085] Exemplarily, please refer to Figure 7 and Figure 10 , Figure 10 is a sectional view of a first cup lid provided by an embodiment of the present application. The first cup lid 100 in the cup lid 000 further has a second opening 103 communicating with the accommodation space C in the radial direction of the first cup lid 100, and the engaging member 302 in the locking assembly 300 further includes: a connecting portion 3023, and two ends of the connecting portion 3023 are respectively connected to the second sliding portion 3022 and the second engaging portion 3021 in the engaging member 302. Wherein, the connecting portion 3023 can pass through the second opening 103, and the end of the connecting portion 3023 connected to the second sliding portion 3022 is located in the accommodation space C, and the end of the connecting portion 3023 connected to the second engaging portion 3021 is located outside the accommodation space C. Here, the second sliding portion 3022 and the second engaging portion 3021 can be connected as a whole through the connecting portion 2023. In this way, it can be ensured that during the process of the first sliding portion 3012 driving the second sliding portion 3022 to move in the radial direction of the first cup body 100, the second engaging portion 3021 can be synchronously driven to move in the radial direction of the first cup body 100 through the connecting portion 3023. In a possible implementation manner, the second engaging portion 3021, the second sliding portion 3022 and the connecting portion 3023 can be an integrally formed structure.

[0086] In the embodiment of the present application, please refer to Figure 11 , Figure 11 is Figure 1An exploded view of the cup cover is shown. The first cup cover 100 in the cup cover 000 includes: a first cup cover body 104 and a support member 105. The first cup cover body 104 is rotatably connected to the second cup cover 200 in the cup cover 000, the support member 105 is connected to the side of the first cup cover body 104 facing the second cup cover 200, and the support member 105 and the first cup cover body 104 are used to enclose a accommodating space C. The first cup cover body 104 has a first opening 101 on one side facing away from the support member 105. Here, the opening surface of the first opening 101 can be located on the end surface of the first cup cover body 104 facing away from the second cup cover 200.

[0087] That is, the first sliding portion 3011 of the driving member 301 and the second sliding portion 3022 of the clamping member 302 can be installed between the support member 105 and the first cup cover body 104. At least part of the button portion 3012 of the driving member 301 can be exposed through the first opening 101 provided on the first cup cover body 104.

[0088] Optional, please refer to Figure 12 , Figure 12 1 is a schematic diagram of a combination of a first cup cover and a locking assembly provided in an embodiment of the present application. A portion of the button portion 3012 can extend out of the accommodating space C through the first opening 101, and the end surface of the button portion 3012 extending out of the accommodating space C from the first opening 101 can protrude from the end surface of the first cup cover body 104 away from the second cup cover 200. In this way, the user can intuitively and conveniently find the button portion 3012, and it can be more convenient for the user to apply pressing force to the button portion 3012, thereby effectively improving the opening efficiency of the cup cover 000.

[0089] In the examples of this application, please refer to Figure 13 , Figure 13 1 is another schematic diagram of the first cup cover structure provided by an embodiment of the present application. The side of the first cup cover body 104 may have a third opening 107, so that the end of the connecting portion 3023 in the clamping member 302 away from the second sliding portion 3024 can extend through the third opening 107. In this way, it can be ensured that the first cup cover body 104 will not block the clamping member 302 from moving in the radial direction of the first cup body 101, so that after the clamping member 302 moves in the radial direction of the first cup body 101 in a direction away from the driving member 301, the second clamping portion 3022 in the clamping member 302 can be normally separated from the first clamping portion 201 provided on the second cup body 200.

[0090] Optionally, the second cup cover 200 in the cup cover 000 has a water outlet 202 ; the first cup cover 100 in the cup cover 000 further includes: a sealing member 106 connected to a side of the support member 105 in the first cup cover 100 away from the first cup cover body 104 .

[0091] Among them, the seal 106 has a first sealing protrusion 1061 for sealing the water outlet 202 in the second cup lid 200. Exemplarily, the seal 106 is a structure made of silicone material. In this way, through the close fit of the first sealing protrusion 1061 on the seal 106 and the water outlet 202 in the second cup lid 200, it can effectively prevent the accidental leakage of liquid from the water outlet 202, and maintain a good sealing state even when the water cup is inverted or shaken.

[0092] It should be noted that the second cup lid 200 in the cup lid 000 also has a vent hole 203, and the seal 106 also has a second sealing protrusion 1062 for sealing the vent hole 203.

[0093] Here, by providing the vent hole 203, after the cup lid 000 is connected to the cup body, the vent hole 203 can communicate with the internal space of the cup body to ensure that the internal and external air pressures of the cup body can be balanced through the vent hole 203. And by providing the second sealing protrusion 1062, it can effectively prevent the accidental leakage of liquid from the vent hole 203, and further improve the sealing state even when the water cup is inverted or shaken.

[0094] Optionally, the first engaging portion 201 and the second engaging portion 3021 can be flexibly designed in a complementary concave-convex form, that is, the first engaging portion 201 and the second engaging portion 3021 can be interchanged as an embedded convex block or an embedded groove; if the first engaging portion 201 is designed as an embedded convex block, then the second engaging portion 3021 is matched as an embedded groove; conversely, if the first engaging portion 201 is designed as an embedded groove, then the second engaging portion 3021 is adapted as an embedded convex block. For the sake of clarity, this application will take the first engaging portion 201 as an embedded groove and the second engaging portion 3021 as an embedded convex block as an example for exemplary illustration.

[0095] In this application, as Figure 11 shown, the second cup lid 200 in the cup lid 000 also has a diversion member 206 provided around the water outlet 202, and an embedded groove is provided on the diversion member 206. Among them, after the first cup lid 100 and the second cup lid 200 are snapped together, at least part of the embedded convex block can be located in the embedded groove, so that the first cup lid 100 and the second cup lid 200 can be tightly snapped together; after the pressing force is applied to the button portion 3011 in the driving member 301, the pressing force will be transmitted to the first sliding portion 3012, so that the first sliding portion 3012 can drive the second sliding portion 3022 in the engaging member 302 away from the first sliding portion 3012, so that the embedded convex block can be disengaged from the embedded groove to realize the separation of the first cup lid 100 and the second cup lid 200.

[0096] In the embodiment of this application, please refer to Figure 14 , Figure 14It is a schematic structural diagram of a filtering component provided by an embodiment of the present application. The cup lid 000 further includes a filtering component 400 connected to the side of the second cup lid 200 facing away from the first cup lid 100. The filtering component 400 can perform refined filtration on the beverage, removing tea leaves, coffee grounds or other solid particles, while allowing the liquid to pass through smoothly, ensuring that the user obtains a pure and impurity-free taste experience when drinking.

[0097] Exemplarily, please refer to Figure 15 , Figure 15 It is a schematic structural diagram of another second cup lid provided by an embodiment of the present application. The second cup lid 200 in the cup lid 000 includes a second cup lid body 204 and a connecting cylinder 205. The second cup lid body 204 is rotatably connected to the first cup lid 100 in the cup lid 000, and the connecting cylinder 205 is fixedly connected to the side of the second cup lid body 204 facing away from the first cup lid 100. The connecting cylinder 205 is used to connect to the cup body. Exemplarily, the outer wall of the connecting cylinder 205 may have an external thread, and the cup body may have an internal thread. The connecting cylinder 205 and the cup body can be connected by screwing.

[0098] Wherein, there are a plurality of first limiting members (not shown) on the inner wall of the end of the connecting cylinder 205 facing away from the second cup lid body 204, and a plurality of second limiting members (not shown) corresponding to the plurality of first limiting members one by one on the outer edge of the filtering component 400. Each second limiting member is used to abut against the corresponding first limiting member.

[0099] In this way, after the first limiting member and the second limiting member abut against each other one by one, the filtering component 400 can be stably installed on the second cup lid 200. In addition, such a design is not only convenient for assembly, but also ensures that the position of the filtering component 400 is stable during use and will not be easily displaced or fall off.

[0100] In an embodiment of the present application, one of the first limiting member in the connecting cylinder 205 and the second limiting member in the filtering component 400 is a limiting protrusion Q, and the other is a limiting chute P.

[0101] Wherein, the limiting chute P extends around the axis of the connecting cylinder 205, and the extending direction of the limiting chute P is perpendicular to the axis of the connecting cylinder 205. That is to say, the limiting chute P can be an arc-shaped strip chute extending around the axis of the connecting cylinder 205. Correspondingly, the limiting protrusion Q cooperating with the limiting groove P can also be an arc-shaped strip protrusion extending around the axis of the connecting cylinder 205. After the filtering component 400 is connected to the end of the connecting cylinder 205 facing away from the second cup lid body 204, at least part of the limiting protrusion Q is located in the limiting chute P.

[0102] Exemplarily, after the filtering component 400 is connected to the end of the connecting cylinder 205 facing away from the second cup cover body 204, all of the limiting protrusions Q are located within the limiting sliding grooves P.

[0103] In this case, through the cooperation of the limiting protrusions Q and the limiting sliding grooves P, a firm connection between the filtering component 400 and the connecting cylinder 205 is achieved. After the filtering component 400 is connected to the connecting cylinder 205, the limiting protrusions Q are embedded into the limiting sliding grooves P, which can ensure the stable docking between the two and can effectively prevent the filtering component 400 from rotating or falling off during use, increasing the convenience and safety of use.

[0104] In the embodiment of the present application, the limiting sliding groove P has an inlet and a limiting blind end that are oppositely arranged in the extending direction of the limiting sliding groove P, and the inlet of the limiting sliding groove P can be used for the limiting protrusion Q to slide in.

[0105] Wherein, after at least part of the limiting protrusion Q slides into the limiting sliding groove P through the inlet, the limiting blind end of the limiting sliding groove P contacts the end of the limiting protrusion Q.

[0106] Exemplarily, in the case where the filtering component 400 needs to be installed on the side of the connecting cylinder 205 facing away from the second cup cover body 204, the first end of the limiting protrusion Q is aligned with the inlet of the limiting sliding groove P, and the filtering component 400 and the connecting cylinder 205 are relatively rotated around the first rotation direction, so that the limiting protrusion Q can gradually slide into the limiting sliding groove P through the inlet until the first end of the limiting protrusion Q contacts the limiting blind end of the limiting sliding groove P, which can ensure that at least part of the limiting protrusion Q is located within the limiting sliding groove P, and thus the connection between the filtering component 400 and the side of the connecting cylinder 205 facing away from the second cup cover body 204 can be achieved.

[0107] Correspondingly, in the case where the filtering component 400 needs to be disassembled from the side of the connecting cylinder 205 facing away from the second cup cover body 204, the filtering component 400 and the connecting cylinder 205 are relatively rotated around the second rotation direction, and the second end of the limiting protrusion Q can gradually slide out of the limiting sliding groove P through the inlet of the limiting sliding groove P until all of the limiting protrusion Q slides out of the limiting sliding groove P, and then the filtering component 400 can be disassembled from the connecting cylinder 205.

[0108] It should be noted that the first rotation direction in the above embodiment can be one of the clockwise direction and the counterclockwise direction, and the second rotation direction can be the other of the clockwise direction and the counterclockwise direction.

[0109] Optionally, as Figure 14 and Figure 15 shown, the limiting protrusion Q has a clamping groove 401, and the limiting sliding groove P has a clamping protrusion 2051 that cooperates with the clamping groove 401.

[0110] Wherein, after at least part of the limiting protrusion Q is located in the limiting chute P, at least part of the clamping protrusion 2051 is located in the clamping groove 401. In this way, through the cooperation and clamping of the clamping protrusion 205 and the clamping groove 401, a more stable connection between the filter assembly 400 and the second cup cover 200 can be ensured.

[0111] In the embodiment of the present application, when the first limiting member is the limiting chute P, on the inner wall of the connecting cylinder 205 of the second cup cover 200 away from one end of the second cup cover body 204, there are a plurality of first guiding strips 2052, a plurality of second guiding strips 2053 and a plurality of limiting strips 2054.

[0112] Wherein, the extending directions of the first guiding strip 2052 and the second guiding strip 2053 in the connecting cylinder 205 are both parallel to the extending direction of the limiting chute P, the extending length of the first guiding strip 2052 is less than the extending length of the second guiding strip 2053, and the second guiding strip 2053 is closer to the second cup cover body 204 than the first guiding strip 2052; the extending direction of the limiting strip 2054 intersects with the extending direction of the limiting chute P. For example, the extending direction of the limiting strip 2054 can be perpendicular to the extending direction of the limiting chute P.

[0113] Wherein, the plurality of first guiding strips 2052 in the connecting cylinder 205 correspond to the plurality of second guiding strips 2053 one by one, and correspond to the limiting strips 2054 one by one. Both ends of each limiting strip 2054 are fixedly connected to one end of the corresponding first guiding strip 2052 and one end of the second guiding strip 2053 respectively, and the corresponding limiting strip 2054, first guiding strip 2052 and second guiding strip 2053 are used to enclose a limiting chute P.

[0114] It should be noted that the side of the limiting strip 2054 facing the limiting chute P is the limiting blind end of the limiting chute P, and the area between the end of the first guiding strip 2052 away from the limiting strip 2054 and the corresponding position of the second guiding strip 2053 is the entrance of the limiting chute P.

[0115] In this case, since the extension length of the second guiding strip 2053 is greater than that of the first guiding strip 2052, and the second guiding strip 2053 can be closer to the second cup lid body 204 relative to the first guiding strip 2052. Therefore, during the process of installing the filtering component 400 on the connecting cylinder 205, the limiting protrusion Q on the filtering component 400 can first contact the part of the second guiding strip 2053 that protrudes from the first guiding strip 2052, and then under the guiding action of the second guiding strip 2053, it can ensure that the limiting protrusion Q smoothly slides into the limiting chute P through the entrance of the limiting chute P, and the part of the limiting protrusion Q that slides into the limiting chute P can be limited by the first guiding strip 2052 to ensure that the filtering component 400 will not easily fall off the connecting cylinder 205.

[0116] In summary, the present application provides a cup lid, including a first cup lid, a second cup lid and a locking component. Since at least a part of the locking component can pass through the first opening and be exposed outside the accommodating space of the first cup lid, users can directly contact and operate the locking component. At the same time, the second clamping portion in the locking component can match and tightly combine with the first clamping portion on the second cup lid. In this way, after the first clamping portion and the second clamping portion are clamped, the first cup lid and the second cup lid can be tightly locked through the first clamping portion and the second clamping portion to form a reliable connection. When the cup lid needs to be opened, the user only needs to apply an axial pressing force along the first cup lid to the locking component exposed at the first opening, so that the second clamping portion in the locking component is disengaged from the clamping state with the first clamping portion in the second cup lid, and then the clamping state between the first cup lid and the second cup lid is released to ensure that the first cup lid can rotate relative to the second cup lid in a direction away from the second cup lid. This not only simplifies the operation process of opening the cup lid, improves the user experience, but also ensures the connection strength of the cup lid in the closed state and effectively prevents liquid leakage. In this way, after installing this cup lid on the cup body of the water cup, not only can the water cup be opened or closed by rotating the cup lid, but also the water cup can be opened or closed by controlling the relative rotation of the first cup lid and the second cup lid in the cup lid.

[0117] The embodiment of the present application also provides a water cup. Please refer to Figure 16 , Figure 16 FIG. is a schematic structural diagram of a water cup provided by the embodiment of the present application. The water cup includes a cup body 001 and a cup lid 000 connected to the cup body 001, where the cup lid 000 is the cup lid 000 in any of the above items.

[0118] In the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The term "plurality" means two or more, unless otherwise clearly defined.

[0119] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
