Description

Technical Field

[0001] This utility model relates to the field of cup lid technology, and more specifically, to a multifunctional cup lid. Background Technology

[0002] A cup lid is an accessory used to install on a cup body. Currently, Chinese Patent Announcement No. CN221980503U discloses a rotating spout cup lid. During use, when the spout needs to extend out of the lid, the rotation of the spout needs to be done manually, which is inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multifunctional cup lid, in which the suction nozzle can automatically extend out of the receiving cavity when the button assembly is pressed during use, thereby making the use of the cup lid more convenient.

[0004] This utility model provides a multifunctional cup lid, including a base, a lid body, a spout, a button assembly, and a rotary drive mechanism. The rear end of the spout is rotatably connected to the inner bottom of the base, and the rotary drive mechanism is fixed to the inner bottom of the base. The spout is connected to the drive end of the rotary drive mechanism. The lid body is fixed to the opening at the upper end of the base, and a receiving cavity is provided on the lid body. When the spout is rotated to a horizontal state, the receiving cavity is used to accommodate the spout. The button assembly is connected to the lid body and is used to trigger the control end of the rotary drive mechanism. When the button assembly is pressed to trigger the control end of the rotary drive mechanism, the rotary drive mechanism drives the spout to rotate so that the front end of the spout extends out of the receiving cavity and keeps the spout in a vertical state.

[0005] In use, when it is necessary for the tip of the nozzle to extend out of the accommodating cavity, the user only needs to press the button assembly. When the button assembly is pressed, it triggers the control end of the rotary drive mechanism. At this time, the rotary drive mechanism can drive the nozzle to rotate so that the tip of the nozzle extends out of the accommodating cavity and keeps the nozzle in a vertical position. That is, the nozzle can automatically extend out of the accommodating cavity, thus making the use of the cup lid more convenient.

[0006] In one possible implementation, the rotary drive mechanism includes a housing assembly, a rotating sleeve, a movable sleeve, and a torsion spring. The housing assembly is fixed to the inner bottom of the base. The rotating sleeve is rotatably connected inside the housing assembly, and the nozzle is drively connected to the rotating sleeve. A rotation limiting structure is provided between the rotating sleeve and the housing assembly so that the rotating sleeve can only drive the nozzle to rotate within a certain angle range. The movable sleeve is axially movable inside the rotating sleeve and circumferentially limited by the rotating sleeve. The right end of the movable sleeve extends outside the housing assembly and forms the control end of the rotary drive mechanism. A locking structure is provided between the movable sleeve and the housing assembly. When the button assembly releases the trigger state of the control end of the rotary drive mechanism, the locking structure is used to lock the movable sleeve to restrict the free rotation of the movable sleeve, the rotating sleeve, and the nozzle. The left end of the torsion spring is connected to the housing assembly and circumferentially limited, and the right end of the torsion spring is inserted into the left end of the movable sleeve and circumferentially limited by the movable sleeve. The torsion spring is used to apply a force to the movable sleeve to drive the locking structure to lock the movable sleeve, and to apply a force to the movable sleeve to drive the nozzle to rotate within a certain angle range. The rotational force of the moving sleeve and the nozzle; by adopting this rotary drive mechanism, when the button assembly is pressed to trigger the control end of the rotary drive mechanism, that is, when the button assembly pushes the moving sleeve, the moving sleeve can move relative to the rotating sleeve, and the locking structure can release the locking state of the moving sleeve. At this time, the torsion spring can drive the moving sleeve to rotate. Due to the circumferential limitation between the moving sleeve and the rotating sleeve, the moving sleeve can drive the rotating sleeve to rotate synchronously. When the rotating sleeve rotates, it can drive the nozzle to rotate so that the front end of the nozzle extends out of the receiving cavity. At this time, the nozzle can be in a vertical state. After the nozzle is rotated to the vertical state, and when the button assembly is released, the button assembly can release the trigger state of the control end of the rotary drive mechanism, that is, the button assembly can release the pushing state of the moving sleeve. At this time, the torsion spring can push the moving sleeve to move and reset relative to the rotating sleeve, and the moving sleeve and the housing assembly can be locked again by the locking structure. That is, the moving sleeve, the rotating sleeve and the nozzle cannot be rotated, thereby keeping the nozzle in a vertical state.

[0007] In one possible implementation, the rotation limiting structure includes an arc-shaped hole on the left end of the housing assembly, a rod at the edge of the left end of the rotating sleeve, the rod extending through the arc-shaped hole and out of the housing assembly to form the driving end of the rotation drive mechanism, and a socket on one side of the rear end of the nozzle, the socket being eccentrically positioned with respect to the rotation center of the nozzle, the rod being inserted into the socket; when the nozzle rotates to a horizontal position, the rod abuts against one end of the arc-shaped hole, and when the nozzle rotates to a vertical position, the rod abuts against the other end of the arc-shaped hole; with this structure, after the rod and the socket are engaged, the nozzle can be reliably driven to rotate when the rotating sleeve rotates. Furthermore, when the nozzle rotates to a horizontal position, the rod abuts against one end of the arc-shaped hole, and when the nozzle rotates to a vertical position, the rod abuts against the other end of the arc-shaped hole, ensuring that the rotating sleeve can only drive the nozzle to rotate within a certain angle range, and this certain angle range is - degrees.

[0008] In one possible implementation, guide blocks are provided at both ends of the rotating sleeve in the axial direction, and arc-shaped guide grooves corresponding to the guide blocks are provided on the inner wall of the housing assembly. Each guide block is slidably connected in the guide groove on the corresponding side. With this structure, under the cooperation of the guide blocks and guide grooves, when the rotating sleeve rotates relative to the housing assembly, the guide blocks can slide in the guide grooves, which can guide and limit the rotation of the rotating sleeve, thereby making the rotation of the rotating sleeve smoother. In addition, the two ends of the rotating sleeve in the axial direction abut against the inner walls of both sides of the housing assembly to achieve axial limitation of the rotating sleeve.

[0009] In one possible implementation, a limiting block is provided on the outer wall of the movable sleeve, and a limiting groove is provided on the inner wall of the rotating sleeve. The limiting block is embedded in the limiting groove and can slide relative to the limiting groove along the axial direction of the rotating sleeve. With this structure, after the limiting block and the limiting groove are engaged, circumferential limiting of the movable sleeve and the rotating sleeve can be achieved. In addition, the movable sleeve can reliably slide axially relative to the rotating sleeve.

[0010] In one possible implementation, the locking structure includes at least one locking block disposed on the outer side wall of the movable sleeve, and a locking groove is provided on the inner end face of the housing assembly. When the nozzle rotates to a horizontal or vertical position, and the button assembly releases the trigger state of the control end of the rotary drive mechanism, each locking block is used to engage with the locking groove at the corresponding position to restrict the free rotation of the movable sleeve, the rotating sleeve, and the nozzle. With this structure, when the nozzle rotates to a horizontal position, and the button assembly releases the trigger state of the control end of the rotary drive mechanism, each locking block can engage with the locking groove at the corresponding position. The locking slots engage with the movable sleeve, rotating sleeve, and nozzle to restrict the free rotation of the sleeve, the nozzle, and the nozzle itself, thus keeping the nozzle in a horizontal position. Similarly, when the nozzle rotates to a vertical position, and the button assembly releases the trigger state of the control end of the rotary drive mechanism, each locking block engages with the locking slot at the corresponding position to restrict the free rotation of the movable sleeve, rotating sleeve, and nozzle, thus keeping the nozzle in a vertical position. This achieves locking of the nozzle in both horizontal and vertical positions, thereby restricting the free rotation of the nozzle when it rotates to either a horizontal or vertical position.

[0011] In one possible implementation, the left end of the torsion spring engages with a slot on the inner wall of the housing assembly, and the end of the left end of the torsion spring engages with a groove on the inner wall of the housing assembly for circumferential limiting; the end of the right end of the torsion spring engages with an opening groove on the inner wall of the movable sleeve for circumferential limiting; with this structure, the left end of the torsion spring can be reliably connected to the housing assembly and achieve circumferential limiting, and the right end of the torsion spring can be reliably connected to the movable sleeve and achieve circumferential limiting, that is, the torsion spring can reliably apply a rotational force to the movable sleeve to drive the movable sleeve, the rotating sleeve and the suction nozzle to rotate.

[0012] In one possible implementation, the button assembly includes a button and a spring; the button is vertically slidably inserted into the cover, the upper end of the spring is inserted into the lower end of the button, and the lower end of the spring abuts against the inner bottom of the base. The spring is used to apply a spring force to the button to drive it to move upward and reset. A push block is provided on the outer wall of the lower end of the button, and a slope is provided on the side wall of the lower end of the push block. The right end of the movable sleeve forms an outwardly convex dome. When the button is pressed, the slope is used to fit against the dome so that the button pushes against the movable sleeve. With this structure, when the button is pressed down, the slope can fit against the dome, and the button can reliably push against the movable sleeve. That is, when the button is pressed down, the button assembly can reliably trigger the control end of the rotary drive mechanism.

[0013] In one possible implementation, at least one slider is provided on the outer wall of the button, and a groove corresponding to the slider is provided on the lower end face of the cover. The slider is vertically slidably connected in the groove, and the button is circumferentially limited by the slider and the groove. By adopting this structure, after the slider and the groove are slidably connected, when the button is pressed, it can not only guide the button, but also limit the circumferential movement of the button and the cover, thereby improving the reliability of the button when moving vertically.

[0014] In one possible implementation, a rotating shaft is provided on both sides of the rear end of the nozzle. A pressure plate is provided above the rotating shaft on the side away from the rotation drive mechanism. The pressure plate is fixed to the inner bottom of the base. The rotating shaft on the side away from the rotation drive mechanism is rotatably connected between the pressure plate and the inner bottom of the base. With this structure, the rear end of the nozzle can be reliably rotatably connected to the inner bottom of the base. Attached Figure Description

[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] See Figure 1-10 As shown in the figure, this application discloses a multifunctional cup lid, including a base 1, a lid body 2, a spout 3, a button assembly 4, and a rotary drive mechanism 5; the rear end of the spout 3 is rotatably connected to the inner bottom of the base 1, the rotary drive mechanism 5 is fixed to the inner bottom of the base 1, the spout 3 is connected to the drive end of the rotary drive mechanism 5, the lid body 2 is fixed to the opening at the upper end of the base 1, and a receiving cavity 21 is provided on the lid body 2; when the spout 3 is rotated to a horizontal state, the receiving cavity 21 is used to receive the spout 3; the button assembly 4 is connected to the lid body 2, and the button assembly 4 is used to trigger the control end of the rotary drive mechanism 5; when the button assembly 4 is pressed to trigger the control end of the rotary drive mechanism 5, the rotary drive mechanism 5 is used to drive the spout 3 to rotate so that the front end of the spout 3 extends out of the receiving cavity 21 and keeps the spout 3 in a vertical state.

[0030] The rotary drive mechanism 5 includes a housing assembly 51, a rotating sleeve 52, a movable sleeve 53, and a torsion spring 54. The housing assembly 51 is fixed to the inner bottom of the base 1. The rotating sleeve 52 is rotatably connected inside the housing assembly 51, and the suction nozzle 3 is drively connected to the rotating sleeve 52. A rotation limiting structure is provided between the rotating sleeve 52 and the housing assembly 51 so that the rotating sleeve 52 can only drive the suction nozzle 3 to rotate within a certain angle range. The movable sleeve 53 is axially movable inside the rotating sleeve 52 and is circumferentially limited by the rotating sleeve 52. The right end of the movable sleeve 53 extends out of the housing assembly. The control end of the rotary drive mechanism 5 is formed outside the housing assembly 51. A locking structure is provided between the movable sleeve 53 and the housing assembly 51. When the button assembly 4 releases the trigger state of the control end of the rotary drive mechanism 5, the locking structure is used to lock the movable sleeve 53 to restrict the free rotation of the movable sleeve 53, the rotating sleeve 52, and the suction nozzle 3. The left end of the torsion spring 54 is connected to the housing assembly 51 and circumferentially limited, and the right end of the torsion spring 54 is inserted into the left end of the movable sleeve 53 and circumferentially limited. The torsion spring 54 is used to apply a driving force to the movable sleeve 53 to lock the movable sleeve 53. The spring force of 53, and the rotational force applied to the movable sleeve 53 to drive the movable sleeve 53, the rotating sleeve 52, and the suction nozzle 3 to rotate; by adopting this rotary drive mechanism, when the button assembly is pressed to trigger the control end of the rotary drive mechanism, that is, when the button assembly pushes the movable sleeve, the movable sleeve can move relative to the rotating sleeve, and the locking structure can release the locking state of the movable sleeve. At this time, the torsion spring can drive the movable sleeve to rotate. Due to the circumferential limitation between the movable sleeve and the rotating sleeve, the movable sleeve can drive the rotating sleeve to rotate synchronously. When the rotating sleeve rotates, The device can drive the nozzle to rotate so that the front end of the nozzle extends out of the receiving cavity. At this time, the nozzle can be in a vertical position. After the nozzle is rotated to the vertical position, and when the button assembly is released, the button assembly can release the trigger state of the control end of the rotary drive mechanism, that is, the button assembly can release the pushing state of the movable sleeve. At this time, the torsion spring can push the movable sleeve to move and reset relative to the rotating sleeve, and the movable sleeve and the housing assembly can be locked again by the locking structure. That is, the movable sleeve, the rotating sleeve and the nozzle cannot be rotated, so that the nozzle can be kept in a vertical position.

[0031] The rotation limiting structure includes an arc-shaped hole 511 on the left end of the housing assembly 51, and an insertion rod 521 at the edge of the left end of the rotating sleeve 52. The insertion rod 521 extends out of the housing assembly 51 after passing through the arc-shaped hole 511, forming the driving end of the rotation drive mechanism 5. A insertion hole 31 is provided on one side of the rear end of the suction nozzle 3. The insertion hole 31 is eccentrically positioned with respect to the rotation center of the suction nozzle 3, and the insertion rod 521 is inserted into the insertion hole 31. When the suction nozzle 3 rotates to a horizontal position, the insertion rod 521 abuts against one end of the arc-shaped hole 511. When the nozzle 3 is rotated to the vertical position, the insertion rod 521 abuts against the other end of the arc-shaped hole 511. With this structure, after the insertion rod and the insertion hole are engaged, the nozzle can be reliably driven to rotate when the rotating sleeve rotates. In addition, when the nozzle is rotated to the horizontal position, the insertion rod can abut against one end of the arc-shaped hole, and when the nozzle is rotated to the vertical position, the insertion rod can abut against the other end of the arc-shaped hole. This ensures that the rotating sleeve can only drive the nozzle to rotate within a certain angle range, and this certain angle range is 0-90 degrees.

[0032] Guide blocks 522 are provided at both ends of the rotating sleeve 52 in the axial direction. Arc-shaped guide grooves 512 corresponding to the guide blocks 522 are provided on the inner wall of the housing assembly 51. Each guide block 522 is slidably connected in the guide groove 512 on the corresponding side. With this structure, under the cooperation of the guide blocks and guide grooves, when the rotating sleeve rotates relative to the housing assembly, the guide blocks can slide in the guide grooves, which can guide and limit the rotation of the rotating sleeve, thereby making the rotation of the rotating sleeve smoother. In addition, the two ends of the rotating sleeve in the axial direction abut against the inner walls of both sides of the housing assembly to achieve axial limitation of the rotating sleeve.

[0033] A limiting block 531 is provided on the outer wall of the movable sleeve 53, and a limiting groove 523 is provided on the inner wall of the rotating sleeve 52. The limiting block 531 is embedded in the limiting groove 523 and can slide relative to the limiting groove 523 along the axial direction of the rotating sleeve 52. With this structure, after the limiting block and the limiting groove are engaged, the circumferential limiting of the movable sleeve and the rotating sleeve can be achieved. In addition, the movable sleeve can reliably slide axially relative to the rotating sleeve.

[0034] The locking structure includes at least one locking block 532 disposed on the outer wall of the movable sleeve 53, and a locking groove 513 disposed on the inner end face of the housing assembly 51. When the suction nozzle 3 rotates to a horizontal or vertical position, and the button assembly 4 releases the trigger state of the control end of the rotary drive mechanism 5, each locking block 532 is used to engage with the locking groove 513 at the corresponding position to restrict the free rotation of the movable sleeve 53, the rotating sleeve 52, and the suction nozzle 3. With this structure, when the suction nozzle rotates to a horizontal position, and the button assembly releases the trigger state of the control end of the rotary drive mechanism, each locking block can... The locking blocks engage with the locking slots at their respective positions to restrict the free rotation of the movable sleeve, rotating sleeve, and nozzle, thus keeping the nozzle in a horizontal position. Similarly, when the nozzle rotates to a vertical position and the button assembly releases the trigger state of the control end of the rotary drive mechanism, each locking block can also engage with the locking slots at its respective positions to restrict the free rotation of the movable sleeve, rotating sleeve, and nozzle, thus keeping the nozzle in a vertical position. This achieves locking of the nozzle in both horizontal and vertical positions, thereby restricting the free rotation of the nozzle when it rotates to either a horizontal or vertical position.

[0035] The left end of the torsion spring 54 is engaged with the slot 514 on the inner wall of the housing assembly 51, and the end of the left end of the torsion spring 54 is engaged with the groove 515 on the inner wall of the housing assembly 51 and circumferentially limited; the end of the right end of the torsion spring 54 is engaged with the opening groove 533 on the inner wall of the movable sleeve 53 and circumferentially limited; with this structure, the left end of the torsion spring can be reliably connected to the housing assembly and achieve the purpose of circumferential limitation, and the right end of the torsion spring can be reliably connected to the movable sleeve and achieve the purpose of circumferential limitation, that is, the torsion spring can reliably apply a rotational force to the movable sleeve to drive the movable sleeve, the rotating sleeve and the suction nozzle to rotate.

[0036] The button assembly 4 includes a button 41 and a spring 42. The button 41 is vertically slidably inserted into the cover 2. The upper end of the spring 42 is inserted into the lower end of the button 41, and the lower end of the spring 42 abuts against the inner bottom of the base 1. The spring 42 is used to apply a spring force to the button 41 to drive the button 41 to move upward and reset. A push block 411 is provided on the outer wall of the lower end of the button 41, and a slope 412 is provided on the side wall of the lower end of the push block 411. The right end of the movable sleeve 53 forms an outwardly convex dome 534. When the button 41 is pressed, the slope 412 is used to fit with the dome 534 so that the button 41 pushes the movable sleeve 53. With this structure, when the button is pressed down, the slope can fit with the dome, and the button can reliably push the movable sleeve. That is, when the button is pressed down, the button assembly can reliably trigger the control end of the rotary drive mechanism.

[0037] At least one slider 413 is provided on the outer wall of the button 41, and a groove 22 corresponding to the slider 413 is provided on the lower end surface of the cover 2. The slider 413 is vertically slidably connected in the groove 22, and the button 41 is circumferentially limited to the cover 2 by the slider 413 and the groove 22. With this structure, after the slider and the groove are slidably connected, when the button is pressed, it can not only guide the button, but also limit the circumferential movement of the button and the cover, thereby improving the reliability of the button when moving vertically.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
