Abstract
Description
Technical Field
[0001] This application relates to the field of water cup technology, specifically to a safe double drinking cup. Background Technology
[0002] Dual-drink cups are portable water bottles that support both pouring and straw drinking methods, and are widely used in public places such as libraries and schools. However, in these settings, dual-drink cups pose the following two safety hazards: Firstly, regarding passive hygiene risks, double-drink cups in public places often lack clear personal identification and designated storage locations, leading to haphazard placement or pile-up. This disorderly storage easily results in unintentional misuse. Since the cup rim, straw interface, and straw itself come into direct contact with the user's oral mucosa, if the user has an infectious disease, cross-infection can easily occur, posing a health and safety hazard. Secondly, regarding proactive security threats, when unattended, malicious individuals can easily open the lid and throw unknown liquids, solid foreign objects, or even harmful substances into the inner cavity of the cup. Existing double-drink cups cannot prevent others from maliciously throwing dangerous substances into the inner cavity of the cup, thus posing a security risk. Therefore, there is an urgent need for a dual-drinking cup that can not only avoid passive hygiene risks but also prevent active safety threats. Utility Model Content
[0003] In order to overcome the above-mentioned technical problems, the purpose of this application is to provide a safe double-drinking cup, which prevents others from maliciously throwing foreign objects into the cup body through the interlocking function of the lid and the base, thereby improving the safety of the cup body.
[0004] The objective of this application can be achieved through the following technical solutions: Specifically, a safe dual-drink cup is provided, including a cup lid assembly that fits over the opening at the top of the cup body. The cup lid assembly includes a base and a top cover. A locking ring is movably mounted on the bottom end of the base along its axial direction. A rubber ring is nested on the outer side of the locking ring. A second button is installed on the base so that when the locking ring moves on the base, the second button can form an interlocking structure with the locking ring. At this time, the locking ring is compressed to lock it against the inner wall of the cup body. When the top cover is closed, it forms a pin hole with the second button to lock the second button.
[0005] As a further aspect of this application: the bottom and top of the locking ring respectively have an outwardly extending bottom ring and a pad, and when the bottom ring is inside the cup body, the pad is supported on the top opening of the cup body; the top of the rubber ring has a pad ring extending to fit against the bottom surface of the base, and the base moves along the axial direction of the cup body, so that the rubber ring can be compressed to form a locked state with the inner wall of the cup body and rebound to form a relative sliding state with the inner wall of the cup body.
[0006] As a further aspect of this application: a button latch is provided at the bottom of the second button, and a first buckle extending towards the second button is provided at the top of the locking ring so as to form an interlocking structure with the button latch. A limit groove is provided on the second button, and a limit pin is provided on the upper cover so that when the upper cover is closed, the limit pin is engaged with the limit groove to lock the second button.
[0007] As a further aspect of this application: a torsion spring shaft is provided on the base, and an upper rotating seat that cooperates with the torsion spring shaft is provided on the upper cover, so that the upper cover can switch between a closed state and an open state. At this time, the limiting pin produces a pin insertion and removal action relative to the limiting groove.
[0008] As a further aspect of this application: the base is provided with a drive mechanism for switching the top cover from a closed state to an open state; the drive mechanism includes a motor, the output shaft of which is connected to a drive frame via a cam, so that the drive frame can generate horizontal reciprocating motion in the radial direction of the cam; a locking frame is connected to one side of the drive frame, and the inner side of the locking frame is provided with locking buckles and venting buckles distributed in a stepped manner; the bottom of the top cover is provided with an upper locking buckle, and when the top cover is in the closed state, the upper locking buckle passes through the through hole on the base and is engaged in the locking frame.
[0009] As a further aspect of this application: a lower cover is provided between the base and the upper cover, and a lower rotating seat that cooperates with the torsion spring shaft is provided on the lower cover.
[0010] As a further aspect of this application: the top surface of the lower cover is permeated with a venting rubber block and a rubber straw, and the top surface of the base is provided with a drinking port that cooperates with the venting rubber block and the rubber straw. When the lower cover is closed, the venting rubber block and the rubber straw communicate with the inner cavity of the cup body through the drinking port.
[0011] As a further aspect of this application: a first button is provided on the side of the lower cover, and a buckle groove is provided on the top surface of the lower cover. When the lower cover is closed, the first button cooperates with the buckle groove to lock the lower cover.
[0012] As a further aspect of this application, the base is also provided with a fingerprint reader for controlling the drive mechanism.
[0013] As a further aspect of this application: the bottom surface of the base is provided with a movable groove that cooperates with the pad block, a stop block is provided on the side wall of the movable groove, and a second buckle is provided on the locking ring extending to the side of the stop block. When the rubber ring is in a sliding state, the second buckle and the stop block are engaged.
[0014] The beneficial effects of this application are: 1. In this application, when the cup lid assembly needs to be installed on the cup body, simply press the cup lid assembly along the axial direction of the cup body. The cup lid assembly will squeeze the gasket ring, causing the rubber ring to be compressed to form an interlocking locking state with the inner wall of the cup body. This achieves both sealing and fixing of the cup lid assembly and the cup body. When the lid is closed, it can be locked using an existing fingerprint lock. The limiting pin on the lid will engage with the limiting groove, restricting the second button and locking it. At this time, the base cannot be removed from the cup body using the second button, thus locking the base to the cup body. That is, when the lid is not opened, the base cannot be opened either. Only after opening the lid using the fingerprint lock can the base be opened using the second button, preventing others from maliciously throwing foreign objects into the cup body and improving the security of the cup body. This achieves the interlocking function between the lid and the base.
[0015] 2. When it is necessary to remove the lid assembly from the cup body, simply press the second button to separate the button lock on the second button from the first buckle. The lid assembly will automatically spring up under the elastic deformation force of the rubber ring, and the rubber ring will also expand to slide relative to the inner wall of the cup body. At this time, the lid assembly can be separated from the cup body along the axial direction of the cup body. The operation is simple and effortless.
[0016] 3. The motor is started by the fingerprint reader. The motor will drive the cam to rotate at a set angle, which will cause the drive frame to drive the locking frame to make horizontal reciprocating motion in the radial direction. During this process, the locking buckle and the venting buckle on the drive frame will disengage from the upper lock, allowing the lid to open a second time. This can release the hot air inside the cup in advance and prevent splashing.
[0017] 4. With the setting of the limiting pin, when the top cover is closed, it will be locked into the limiting groove on the second button, thus preventing the cup lid assembly from being directly removed from the cup body and improving the safety of use.
[0018] 5. With the setting of the clamp plate, when the top cover is closed, the clamp plate will press on the rubber straw and press the rubber straw on the venting rubber block, sealing the rubber straw and blocking the venting rubber block at the same time, thus achieving the overall sealing of the cup lid assembly.

Detailed Implementation
[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] As one embodiment of this application, such as Figures 1-20As shown, a safe double-drinking cup is disclosed, including a lid assembly 20 that fits over the opening at the top of the cup body 10. The lid assembly 20 has a base 21, on which a second button 24 is provided for switching the base 21 from a locked state to a relatively sliding state. An upper cover 22 is hinged to the base 21, and a limit pin 223 is provided on the upper cover 22. A limit groove 243 is formed on the second button 24. When the upper cover 22 is closed, the limit pin 223 engages with the limit groove 243 to lock the second button 24. When the upper cover 22 is opened, the limit pin 223 disengages from the limit groove 243 to unlock the second button 24. In use, a locking ring 27 is installed at the bottom of the base 21. The bottom and top of the locking ring 27 have outwardly extending... The bottom ring 271 and the pad 272 extend outward. When the bottom ring 271 is inside the cup body 10, the pad 272 is supported on the top opening of the cup body 10. A rubber ring 28 is nested between the bottom ring 271 and the pad 272 on the outer side of the locking ring 27. The top of the rubber ring 28 has a pad ring 281 that extends to fit against the bottom surface of the cup lid assembly 20. The side of the pad ring 281 has a relief groove 282 to facilitate the pad 272 being supported on the top opening of the cup body 10. The base 21 moves along the axial direction of the cup body 10, so that the rubber ring 28 can be compressed to form a locked state with the inner wall of the cup body 10 and rebound to form a relative sliding state with the inner wall of the cup body 10. The top of the locking ring 27 is provided with a first buckle 273 extending towards the side of the second button 24.
[0024] When using, please refer to Figures 4-7 When the base 21 is pressed on the cup body 10, the pad 272 will support the top opening of the cup body 10. As the base 21 continues to move downward at the top port of the cup body 10, the button lock 242 at the bottom of the second button 24 will engage with the first buckle 273. At this time, the rubber ring 28 is compressed to form a locked state with the inner wall of the cup body 10.
[0025] A return spring 244 is also provided on the second button 24. The elastic force of the return spring 244 can act on the second button 24. The second button 24 is mounted on the base 21 through the rotating shaft 241, so that the return spring 244 can stably engage the button lock 242 with the first buckle 273 through the lever principle.
[0026] An accommodating groove 11 is also provided on the inner wall of the cup body 10. When the rubber ring 28 is compressed, it will enter the accommodating groove 11, so that the base 21 and the cup body 10 are sealed and locked together, thereby improving the stability of the base 21.
[0027] When the second button 24 is pressed, the second button 24 rotates, causing the button lock 242 to separate from the first latch 273. At this time, the rubber ring 28 automatically rebounds, causing the base 21 to move upward at the top port of the cup body 10. At this time, the rubber ring 28 and the rebound to the inner wall of the cup body 10 form a relative sliding state, and the base 21 can be opened freely.
[0028] As one embodiment of this application, see [link to relevant documentation]. Figure 11 , Figure 18 and Figure 19 The base 21 is equipped with a drive mechanism 25 for switching the upper cover 22 from a closed state to an open state. The drive mechanism 25 includes a motor 251, and the output shaft of the motor 251 is connected to a drive frame 253 via a cam 252, so that the drive frame 253 can generate horizontal reciprocating motion in the radial direction of the cam 252. A locking frame 254 is connected to one side of the drive frame 253. The inner side of the locking frame 254 is provided with locking buckles 255 and venting buckles 256 distributed in a stepped manner. The bottom of the upper cover 22 is provided with an upper locking buckle 222. When the upper cover 22 is in the closed state, the upper locking buckle 222 passes through the through hole 214 on the base 21 and is engaged in the locking frame 254. During operation, motor 251 is turned on. The output shaft of motor 251 drives drive frame 253 via cam 252. A rectangular groove matching cam 252 is provided inside base 21 near the cam 252. This rectangular groove restricts the rotation of cam 252, causing it to rotate at a certain angle (the specific angle is determined by the specifications of cam 252 and the rectangular groove; the specific arrangement can be arbitrarily determined by those skilled in the art, ensuring that cam 252 rotates at a preset angle). Specifically, cam 252 rotates at the set angle, causing drive frame 253 to complete a horizontal reciprocating motion. Drive frame 253 first drives locking frame 254 to move to the left (towards...). Figure 18 (Based on the reference), the locking buckle 255 separates from the release buckle 222. The release buckle 222, which is separated from the locking buckle 255, will engage with the venting buckle 256. Then the drive frame 253 drives the locking frame 254 to move to the right, so that the release buckle 222 separates from the venting buckle 256. During this process, the cover 22 has a secondary opening process, and the hot air in the inner cavity of the cup body 10 can be released in advance through the venting rubber block 232.
[0029] After the top cover 22 is opened, the limiting pin 223 on the top cover 22 will disengage from the limiting groove 243, releasing the lock of the second button 24. At this time, the base 21 can be removed from the cup body 10 by using the second button 24. When the top cover 22 is closed, the limiting pin 223 on the top cover 22 will engage with the limiting groove 243, restricting the second button 24 and locking the second button 24. At this time, the base 21 cannot be removed from the cup body 10 by the second button 24, thus locking the base 21 to the cup body 10. That is, when the top cover 22 is not opened, the base 21 cannot be opened either. Only when the top cover 22 is opened can the base 21 be opened by the second button 24, preventing others from maliciously putting foreign objects (such as unsanitary or toxic items) into the cup body 10, thus improving the safety of the cup body 10.
[0030] As one embodiment of this application, such as Figure 11 As shown, a retaining plate 224 is fixedly connected to the inner side of the upper cover 22. When the upper cover 22 is closed, the retaining plate 224 will press precisely on the position of the ventilated rubber block 232 and the rubber straw 233, and at the same time seal the ventilated rubber block 232 and the rubber straw 233.
[0031] The base 21 is provided with a torsion spring shaft 211, and the upper cover 22 is provided with an upper rotating seat 221 that cooperates with the torsion spring shaft 211. After the upper cover 22 is opened, the torque of the torsion spring shaft 211 can be transmitted to the upper cover 22 through the upper rotating seat 221, so that the upper cover 22 can be automatically opened to a large angle (e.g., greater than 90°), making it convenient to drink drinking water from the cup body 10 through the rubber straw 233.
[0032] As one embodiment of this application, a lower cover 23 is provided between the base 21 and the upper cover 22. The lower cover 23 is provided with a lower rotating seat 231 that cooperates with the torsion spring shaft 211. When the lower cover 23 is opened, the torque of the torsion spring shaft 211 can be transmitted to the lower cover 23 through the lower rotating seat 231, so that the lower cover 23 can be automatically opened to a large angle (e.g., greater than 90°). The top surface of the lower cover 23 has a ventilation rubber block 232 and a rubber straw 233. The top surface of the base 21 is provided with a drinking port 212 that cooperates with the ventilation rubber block 232 and the rubber straw 233. When the lower cover 23 is closed, the ventilation rubber block 232 and the rubber straw 233 communicate with the inner cavity of the cup body 10 through the drinking port 212.
[0033] The lower cover 23 has a first button 234 on its side and a latch 213 on its top surface. When the lower cover 23 is closed, the first button 234 engages with the latch 213 to lock the lower cover 23. The structure of the engagement between the first button 234 and the latch 213 is the same as that between the second button 24 and the first buckle 273, and will not be described in detail here.
[0034] The base 21 is also equipped with a fingerprint reader 26 for controlling the drive mechanism 25. Specifically, the motor 251 is turned on by the fingerprint reader 26. The fingerprint reader 26 adopts the existing fingerprint reader 26, which can ensure that the motor 251 can be started and drive the cam 252 to rotate one revolution.
[0035] The bottom surface of the base 21 is provided with a moving groove 215 that cooperates with the pad 272. A stop block 216 is provided on the side wall of the moving groove 215. A second buckle 274 extending towards the stop block 216 is provided on the locking ring 27. When the rubber ring 28 is in a sliding state, the second buckle 274 is engaged with the stop block 216 to prevent the locking ring 27 from separating from the base 21.
[0036] The foregoing has provided a detailed description of one embodiment of this application, but the description is merely a preferred embodiment and should not be construed as limiting the scope of this application. All equivalent variations and modifications made within the scope of this application should still fall within the patent coverage of this application.
