Description

Technical Field

[0001] The utility model relates to the technical field of water cups, in particular to a cup cover and a liquid containing device. Background Art

[0002] A water cup is a container used to hold liquids, usually in a cylindrical shape, to facilitate drinking water.

[0003] In places with a large number of children, such as schools, children's playgrounds and other places, in order to ensure that children have water to drink after playing, most of them carry thermoses at this stage; however, in places with a large number of children, there will be problems such as similar water cups being taken by mistake, resulting in water cups being used by other children. Since the physical fitness of each child and whether they are sick are unknown, some weak people are prone to discomfort and carry diseases, causing the problem of disease transmission, which the existing thermoses are difficult to prevent. Summary of the Invention

[0004] In view of the deficiencies in the cup cover protection measures in the prior art, the purpose of the present invention is to provide a cup cover and a liquid containing device that are prevented from being opened by mistake.

[0005] In order to solve the above problems, the present invention provides the following technical solutions:

[0006] A cup cover and a liquid containing device, comprising: the cup cover is used to cover an outer rotating component and can be opened and closed relative to the outer rotating component;

[0007] The cup cover includes a first control member installed in the cup cover, and the first control member is used to control the second control member to move between a coupling position and a disengaging position;

[0008] When the cup cover is closed, the first control member is used to control the second control member to move to a disengaged position;

[0009] When the cup cover is opened, the first control member is used to control the second control member to move to a connection position.

[0010] In some embodiments, a receiving groove is provided inside the cup cover, and the first control component is fixedly installed in the receiving groove.

[0011] In some embodiments, the first control member includes a first magnet.

[0012] In some embodiments, the cup cover further includes a switch mechanism and a switch signal receiver for triggering the switch mechanism;

[0013] The switch mechanism is installed inside the cup cover;

[0014] When the switch signal receiver triggers the switch mechanism to open, the switch mechanism controls the cup cover to open relative to the outer rotating assembly.

[0015] In some embodiments, the switch mechanism includes a motor, a first buckle, and a push rod mounted on the motor;

[0016] When the motor receives the trigger signal from the switch signal receiver, the motor pushes the push rod to move, and the push rod pushes the first buckle to disengage the first buckle from the first hook, thereby opening the cup cover relative to the outer rotating component.

[0017] In some embodiments, the cup cover, the screw thread component, the outer rotating component and the cup body are included:

[0018] The screw thread assembly is mounted on the end of the cup body and is rotatably connected to the end of the cup body. A suction nozzle is provided in the screw thread assembly.

[0019] The outer rotating assembly is sleeved on the outside of the screw thread assembly and can be fixedly and movably connected to the screw thread assembly. The outer rotating assembly is provided with a through hole for the suction nozzle to pass through;

[0020] The cup cover is provided on the outer rotating assembly and can be opened and closed relative to the outer rotating assembly;

[0021] in,

[0022] A second control member is further provided between the thread-screwing assembly and the outer rotating assembly;

[0023] When the cup cover is opened, the first control member controls the second control member to move to the connection position, and the second control member controls the screw thread assembly and the outer rotating assembly to be fixedly connected. When the screw thread assembly and the outer rotating assembly are fixedly connected, when the outer rotating assembly is rotated relative to the cup body, the screw thread assembly and the outer rotating assembly can be rotated synchronously, so that the outer rotating assembly and the screw thread assembly are separated from the cup body;

[0024] When the cup cover is closed, the first control member controls the second control member to move to the disengaged position, and the second control member controls the movable connection between the screw thread assembly and the outer rotating assembly; when the screw thread assembly and the outer rotating assembly are movably connected, when the outer rotating assembly is rotated relative to the cup body, the screw thread assembly does not rotate synchronously with the outer rotating assembly, and the screw thread assembly does not rotate relative to the cup body, so that the outer rotating assembly and the screw thread assembly cannot be detached from the cup body.

[0025] In some embodiments, the liquid containing device is further provided with a movable space, and the movable space is configured to at least allow the second control member to move between a coupled position and a disconnected position.

[0026] In some embodiments, the threading assembly includes an external threading member and an internal support member fixedly connected to each other, and an installation space located between the external threading member and the internal support member; the external threading member is used to be rotatably connected to the outer side of the cup body end, the internal support member is located on the inner side of the cup body end, and the cup body end is located in the installation space;

[0027] The inner support member is provided with an annular groove;

[0028] The activity space is formed by surrounding the annular groove and the externally rotating tooth member.

[0029] In some embodiments, the second control member further includes a second magnet and a first clamping member fixedly connected to the second magnet; the screw thread assembly is provided with a first limiting member engaged with the first clamping member;

[0030] When the cup cover is closed, the first magnet attracts the second magnet, and the second control member moves to a disengaged position, causing the first clamping member to move away from the first limiting member, thereby movably connecting the screw thread assembly and the outer rotating assembly;

[0031] When the cup cover is opened, the second magnet loses the adsorption force of the first magnet, and the second control part moves to the connection position, causing the first clamping part to move toward the first limit part and engage with the first limit part, thereby fixing the screw thread assembly and the outer rotating assembly in connection.

[0032] In some embodiments, there are multiple first limiting members, and the multiple first limiting members are distributed on the inner circumference of the thread-screwing assembly;

[0033] When the screw thread assembly and the outer rotating assembly rotate relative to each other, the cup cover is opened to move the first clamping member toward the first limiting member, and the first clamping member can be clamped on a corresponding one of the first limiting members.

[0034] The beneficial effect of the present invention is that after the cup cover is closed, the locking mechanism movably connects the screw thread assembly and the outer rotating assembly, the screw thread assembly does not rotate synchronously with the outer rotating assembly, and the screw thread assembly does not rotate relative to the cup body, thereby preventing the outer rotating assembly and the screw thread assembly from being separated from the cup body, ensuring that the water in the cup body is not accidentally drunk by others, thereby playing a protective role. After the cup cover is opened, the locking mechanism fixedly connects the outer rotating assembly and the screw thread assembly, allowing the screw thread assembly to rotate synchronously with the outer rotating assembly, thereby separating the outer rotating assembly and the screw thread assembly from the cup body. After the cup cover is opened, it is convenient to drink water, and the screw thread assembly can be separated from the cup body, making it convenient to fill the cup body with water.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0059] For the convenience of describing the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the drawings, the second direction is the front-back direction in the drawings, and the third direction is the up-down direction in the drawings. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction is referred to as the "up" direction, and the z-axis arrow direction is referred to as the "back" direction in the following text. However, in the actual application of this application, this is not limiting.

[0060] like Figure 2 As shown, this embodiment provides a cup cover 100, which includes a screw thread assembly 120, an outer rotating assembly 130, a cup cover 140 and a locking mechanism 150. The screw thread assembly 120 is installed at the end of the cup body 110 and is rotatably connected to the end of the cup body 110. A suction nozzle 123 is provided in the screw thread assembly 120, and the outer rotating assembly 130 is provided with a through hole 126 for the suction nozzle 123 to pass through. When the screw thread assembly 120 is installed with the cup body 110, the screw thread assembly 120 blocks the end of the cup body 110 to prevent the water in the cup body 110 from spilling out. The screw thread assembly 120 is provided with a suction nozzle 123 to facilitate water intake through the suction nozzle 123.

[0061] In this embodiment, the outer rotating assembly 130 is mounted on the outside of the screw assembly 120 and is fixedly and movably connected to the screw assembly 120. The cup 140 is mounted on the outer rotating assembly 130 and can be opened and closed relative to the outer rotating assembly 130. The locking mechanism 150 is installed between the screw assembly 120 and the outer rotating assembly 130. When the cup 140 is opened, the locking mechanism 150 fixes the screw assembly 120 and the outer rotating assembly 130. When the cup 140 is closed, the screw assembly 120 and the outer rotating assembly 130 can rotate relative to each other. That is, when the cup cover 140 is opened, the locking mechanism 150 fixes the outer rotating assembly 130 and the screw thread assembly 120 together. When the screw thread assembly 120 and the outer rotating assembly 130 are fixedly connected, when the outer rotating assembly 130 is rotated relative to the cup body 110, the screw thread assembly 120 and the outer rotating assembly 130 can be rotated synchronously, so that the outer rotating assembly 130 and the screw thread assembly 120 are separated from the cup body 110. When the cup cover 140 is closed, the locking mechanism 150 movably connects the screw thread assembly 120 and the outer rotating assembly 130. When the screw thread assembly 120 and the outer rotating assembly 130 are movably connected, when the screw thread assembly 120 and the outer rotating assembly 130 are rotated relative to the cup body, the screw thread assembly 120 does not rotate synchronously with the outer rotating assembly 130, and the screw thread assembly 120 does not rotate relative to the cup body 110, so that the outer rotating assembly 130 and the screw thread assembly 120 cannot be separated from the cup body 110. When the cup cover 140 is closed, the outer rotating assembly 130 and the screw thread assembly 120 rotate relative to each other, and the screw thread assembly 120 and the cup body 110 are not separated, ensuring that the cup lid 100 cannot be opened, preventing others from accidentally drinking. At the same time, when the cup cover 140 is opened, it is convenient to drink water, and the screw thread assembly 120 can be separated from the cup body 110, making it convenient to fill the cup body 110 with water.

[0062] like Figure 6-7 As shown, in this embodiment, the locking mechanism 150 includes a first control member mounted on the cup cover 140 and a second control member mounted between the screw thread assembly 120 and the outer rotating assembly 130. The first control member is used to control the movement of the second control member between a connected position and a disconnected position. When the cup cover 140 is closed, the first control member controls the second control member to move to the disconnected position, and the second control member controls the movable connection between the screw thread assembly 120 and the outer rotating assembly 130. When the cup cover 140 is opened, the first control member controls the second control member to move to the connected position, and the second control member controls the fixed connection between the screw thread assembly 120 and the outer rotating assembly 130.

[0063] In this embodiment, a movable space is further provided in the cup cover 100, and the movable space is configured to at least allow the second control member to move between the connected position and the disengaged position, thereby ensuring that the second control member controls the fixed connection and movable connection between the screw thread assembly 120 and the outer rotating assembly 130.

[0064] In this embodiment, a receiving groove 128 is provided inside the cup cover 140, and the first control part is fixedly installed in the receiving groove 128; the first control part includes a first magnet 151. The first magnet 151 is fixed in the receiving groove 128 in the cup cover 140 by bonding or clamping. The second control part includes a second magnet 152. When the cup cover 140 is closed, the first magnet 151 attracts the second magnet 152 to move, and the second control part moves to the disengaged position; when the cup cover 140 is opened, the second magnet 152 loses the adsorption force of the first magnet 151, and the second control part moves to the connected position. The adsorption and detachment of the first magnet 151 and the second magnet 152 are used to achieve a fixed connection and a rotational connection between the screw thread assembly 120 and the outer rotating assembly 130, without the need for manual touch operation, and is easy to use.

[0065] like Figure 5-9 As shown, the second control component also includes a first clamping member 153 fixedly connected to the second magnet 152; the screw thread assembly 120 is provided with a first stopper 154 that engages with the first clamping member 153. A guide rail 155 is provided within the outer rotating assembly 130, and the first clamping member 153 is placed and moved within the guide rail 155. The first clamping member 153 is provided with a slot 156 for mounting the second magnet 152. The second magnet 152 is engaged in the slot 156, so that the first clamping member 153 and the second magnet 152 are fixedly mounted. The first stopper 154 is installed on the screw thread assembly 120. When the cup cover 140 is closed, the first magnet 151 attracts the second magnet 152, and the second control component moves to the disengaged position, causing the first clamping member 153 to move away from the first stopper 154, thereby movably connecting the screw thread assembly 120 and the outer rotating assembly 130. When the cup cover 140 is opened, the second magnet 152 loses the attraction force of the first magnet 151, and the second control member moves to the connection position, causing the first clamping member 153 to move toward the first stopper 154 and engage with the first stopper 154, thereby fixedly connecting the screw thread assembly 120 and the outer rotating assembly 130. The first clamping member 153 is separated from and engaged with the first stopper 154 by the attraction and separation of the first magnet 151 and the second magnet 152, without applying additional force to the first clamping member 153, thereby preventing the problem of the first clamping member 153 and the first stopper 154 being unable to separate or engage due to insufficient additional force.

[0066] In this embodiment, there are multiple first stoppers 154, distributed along the inner circumference of the screw thread assembly 120. When the screw thread assembly 120 and the outer rotating assembly 130 rotate relative to each other, the cup cover 140 is opened to move the first engaging member 153 toward the first stopper 154, and the first engaging member 153 can engage with a corresponding first stopper 154. This ensures that after the first engaging member 153 rotates relative to the screw thread assembly 120 along with the outer rotating assembly 130, when the cup cover 140 is opened, the first engaging member 153 can promptly engage with the first stopper 154, thereby securing the screw thread assembly 120 and the outer rotating assembly 130. This allows for quick separation of the screw thread assembly 120 from the cup body 110 when needed.

[0067] like Figure 10 As shown, in another embodiment, the first control member further includes a toggle member 251 mounted on the cup cover 140. The second control member includes a follower member 252 mounted on the outer rotating assembly 130, and the follower member 252 is movable. When the cup cover 140 is closed, the toggle member 251 pushes the follower member 252 to move; the screw thread assembly 120 is movably connected relative to the outer rotating assembly 130; when the cup cover 140 is opened, the toggle member 251 pushes the follower member 252 to move in the opposite direction, and the screw thread assembly 120 and the outer rotating assembly 130 are fixedly connected. Only by opening and closing the cup cover 140 can the screw thread assembly 120 and the outer rotating assembly 130 be directly fixedly connected and rotated without manual touch operation.

[0068] like Figure 10-12 As shown, in another embodiment, the locking mechanism 150 further includes a second clamping member 253 and a second stopper 254. The second clamping member 253 is fixedly mounted to the follower 252 and is mounted to the outer rotating assembly 130 along with the follower 252. The second stopper 254 is mounted on the screw thread assembly 120, and the second clamping member 253 is placed on the second stopper 254 to secure the screw thread assembly 120 to the outer rotating assembly 130.

[0069] When the cup cover 140 is closed, the toggle member 251 pushes the follower 252 to move the second engaging member 253 away from the second stopper 254, separating the second engaging member 253 from the second stopper 254 and movably connecting the thread assembly 120 and the outer rotating assembly 130. When the cup cover 140 is opened, the toggle member 251 pushes the follower 252 in the opposite direction to move the second engaging member 253 toward the second stopper 254, engaging the second engaging member 253 with the second stopper 254 and fixedly connecting the thread assembly 120 and the outer rotating assembly 130. By using the toggle member 251 to push the follower 252 to separate and engage the second engaging member 253 and the second stopper 254, there is no need to worry about the difficulty of separating or engaging the second engaging member 253 and the second stopper 254.

[0070] In another embodiment, the outer rotating assembly 130 and the cup 140 are hingedly mounted, with a toggle member 251 mounted at the intersection and fixed to the cup 140. The toggle member 251 is a gear, and the driven member 252 is a rack. As the toggle member 251 rotates about the hinge with the cup 140, it pushes the driven member 252 to rotate, thereby separating or engaging the second engaging member 253 with the second retaining member 254. Using a gear as the toggle member 251 and a rack as the driven member 252 makes the separation and engagement of the second engaging member 253 with the second retaining member 254 more stable.

[0071] In this embodiment, the screw thread assembly 120 includes an external screw thread part 121 and an internal support part 122 that are fixedly connected. The screw thread assembly 120 also includes an installation space located between the external screw thread part 121 and the internal support part 122, and the end of the cup body 110 is located in the installation space. The external screw thread part 121 is used to be rotatably connected to the outer side of the end of the cup body 110, and the internal support part 122 is located on the inner side of the end of the cup body 110. An internal thread 124 is provided on the inner side of the external screw thread part 121, and an external thread 125 that cooperates with the external screw thread part 121 is provided on the outer edge of the end of the cup body 110. The cup body 110 is rotationally connected to the external screw thread part 121 via the internal thread 124 and the external thread 125; the internal thread 124 and the external thread 125 realize the fixation and separation of the cup body 110 and the external screw thread part 121. An annular groove 12a is defined on the inner support member 122. The groove and the outer screw thread member define a movable space. A first stopper 154 is positioned within the groove 12a. The first engaging member 153 moves away from and toward the first stopper 154 via the groove 12a. This reciprocating motion of the groove 12a ensures that the first stopper 154 does not prevent the outer rotating assembly 130 from rotating relative to the screw thread assembly 120.

[0072] In this embodiment, the cup cover 100 further includes a switch mechanism 160 and a switch signal receiver 170 that triggers the switch mechanism 160. The switch mechanism 160 is mounted inside the cup cover 140. When the switch signal receiver 170 triggers the switch mechanism 160 to open, the switch mechanism 160 controls the cup cover 140 to open relative to the outer rotating assembly 130. By triggering the switch mechanism 160 through the switch signal receiver 170, the risk of the cup cover being directly opened can be eliminated.

[0073] In this embodiment, the switch mechanism 160 includes a motor 161, a first buckle 163, and a push rod 162 mounted on the motor 161. The outer rotating assembly 130 is provided with a first hook 164 that cooperates with the first buckle 163. A screw 165 is provided on the rotating shaft of the motor 161, and a thread 166 is provided in the push rod 162. When the motor 161 rotates, the screw 165 and the thread 166 push the push rod 162 to move. When the motor 161 receives a trigger signal from the switch signal receiver 170, the motor 161 pushes the push rod 162 to move, and the push rod 162 pushes the first buckle 163 to disengage the first buckle 163 from the first hook 164, thereby opening the cup cover 140 relative to the outer rotating assembly 130. The use of the motor 161 for pushing solves the problem that children have little strength and find it difficult to open the cup cover 140.

[0074] like Figure 13 In another embodiment, the switch mechanism 160 includes an electric cylinder 261 and a second latch 262. The outer rotating assembly 130 is provided with a second hook 263 that engages with the second latch 262. When the electric cylinder 261 receives a trigger signal from the switch signal receiver 170, it directly pushes the second latch 262 to disengage from the second hook 263, thereby opening the cup cover 140 relative to the outer rotating assembly 130. Using the electric cylinder 261 for pushing solves the problem of children having difficulty opening the cup cover 140 due to their limited strength.

[0075] In this embodiment, the switch signal receiver 170 is a fingerprint controller, an electronic password controller, a face recognition controller or a QR code recognition controller, etc., which can prevent the cup cover from being opened after the liquid containing device 200 is taken away by others. When the cup cover cannot be opened, the locking mechanism makes the screw thread assembly and the outer rotating assembly movably connected. When the outer rotating assembly is rotated relative to the cup body, that is, when an outsider unscrews the cup cover, the screw thread assembly does not rotate synchronously with the outer rotating assembly, and the screw thread assembly does not rotate relative to the cup body, that is, at this time, the outer rotating assembly is idling, and the outer rotating assembly and the screw thread assembly cannot be detached from the cup body, that is, the cup cover cannot be opened. The utility model can avoid the potential risks brought about by others unscrewing the cup cover at will.

[0076] like Figure 1 As shown, this embodiment provides a liquid containing device 200, which includes a cup body 110, and an opening is provided at the end of the liquid containing device 200; the cup cover 100 is installed at the end of the cup body 110, and the combination of the cup cover 100 and the cup body 110 can prevent water from spilling.

[0077] like Figure 3As shown, in this embodiment, the liquid receiving device 200 further includes a base 201 and a straw 202. The base 201 is bonded or clamped to the other end of the cup body 110. The straw 202 is placed within the cup body 110, with one end of the straw 202, adjacent to the screw thread assembly 120, positioned within the nozzle opening 123, and the other end of the straw 202 positioned at the bottom of the cup body 110.

[0078] To sum up, the utility model provides a liquid containing device. After the cup cover is opened, the locking mechanism fixes the outer rotating component and the screw thread component in connection, so that the screw thread component and the outer rotating component can rotate synchronously, thereby separating the outer rotating component and the screw thread component from the cup body, that is, the cup cover is opened. After the cup cover is opened, it is convenient to drink water and to fill the cup body with water.

[0079] When the cup cover is closed, the locking mechanism movably connects the screw thread assembly and the outer rotating assembly. The screw thread assembly does not rotate synchronously with the outer rotating assembly, and the screw thread assembly does not rotate relative to the cup body. This prevents the outer rotating assembly and the screw thread assembly from detaching from the cup body, ensuring that the cup cover cannot be opened and the outer rotating assembly is effectively idling. This prevents the water in the cup from being accidentally drunk by others and prevents other objects from being added to the cup body, thus providing a protective effect.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
