Cup Lid

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Utility Model Patent Application No. 202423070554.7, titled “New-type cup lid” filed on Dec. 12, 2024, the content of which, including the amendments thereof, is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the technical field of cup lids, particularly to a new-type cup lid.

BACKGROUND

As a daily necessity, the design of a water cup's lid directly affects its convenience of use, sealing reliability, and ease of cleaning and maintenance. Currently, cup lids on the market fall into two main categories: one is a simple sealing lid with only basic leak-proof functionality, and the other is a multifunctional lid that extends drinking methods or other additional features through structural design.

Among multifunctional lids, the dual-opening design is particularly common, typically featuring a straw hole and a direct-drinking hole to meet users'diverse drinking needs. However, such lids generally suffer from the following issues.

First, traditional dual-opening lids often employ independent hinged covers for the openings, which are opened or closed by flipping or sliding. This design not only increases the number of parts and assembly steps but also shortens product lifespan due to the wear and tear of the hinge structure, leading to higher production and maintenance costs. Additionally, users often need to perform a plurality of operations (such as opening the cover and adjusting the straw) during use, making the process cumbersome. This is especially problematic in scenarios like outdoor activities or sports, where one-handed operation is difficult.

SUMMARY

The present disclosure provides a new-type cup lid to address the issues raised in the background technology.

To achieve the above object, the present disclosure adopts the following technical solutions:

A new-type cup lid, comprising: a cup lid body provided with an accommodation part; a straw component, partially disposed in the accommodation part; and an upper cover rotatably sleeved on the cup lid body and provided with an opening part corresponding to the accommodation part. The upper cover is configured to, when rotated relative to the cup lid body, interact with the straw component to drive the straw component to bend within the accommodation part, thereby switching between a first state where a drinking part of the straw component extends out through the opening and a second state where the straw component is bent to achieve sealing.

The present disclosure further provides another technical solution: a new-type cup lid, comprising: a cup lid body provided with an accommodation part; a straw component partially disposed in the accommodation part; an upper cover rotatably sleeved on the cup lid body and provided with an opening part corresponding to the accommodation part; wherein the upper cover is configured to, rotated relative to the cup lid body, interact with the straw component to drive the straw component to bend within the accommodation part, thereby switching between a first state where a drinking part of the straw component extends out through the opening and a second state where the straw component is bent to achieve sealing; and a locking mechanism disposed on the cup lid body, the locking mechanism being operable to selectively prevent the upper cover from rotating relative to the cup lid body.

The beneficial effects of the present disclosure compared to existing technology are as below:

This application synchronously drives the internal linkage mechanism through the single operation of rotating the upper cover, enabling the flexible straw to be stably bent and effectively flattened at a preset position, thereby achieving reliable sealing to prevent liquid leakage. The design simplifies the sealing process of the cup lid into a simple rotational action, greatly enhancing user convenience. Additionally, the connection between the upper cover and the cup lid body is realized through the fitting of the sliding chute and slider, ensuring not only smoother rotation but also effectively preventing accidental detachment due to deformation, guaranteeing the stability and durability of the overall connection.

It should be noted that similar numbers and letters indicate similar items in the following drawings, therefore once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

Please refer to FIGS. 1 and 2. A new-type cup lid includes a cup lid body 100 and an upper cover 200, with the upper cover 200 sleeved over the cup lid body 100.

In this embodiment, please refer to FIGS. 1, 2, 3, and 4. The cup lid body 100 is provided with an accommodation part, the bottom of which is opened with an insertion hole 111. A straw component is installed in the insertion hole 111. Meanwhile, the surface of the upper cover 200 is provided with an opening part. When the upper cover 200 is sleeved over the outer surface of the cup lid body 100, the straw component can extend through the opening part for ease of use.

It should be noted that in this embodiment, the accommodation part is a recess 110, the opening part is a through hole 210, and the straw component is a flexible straw 300.

In this embodiment, please refer to FIGS. 4 and 6. The inner wall of the upper cover 200 is provided with a first slider 220, while the outer side of the cup lid body 100 is provided with a sliding chute 120, which cooperates with the first slider 220 on the inner wall of the upper cover 200, allowing the upper cover 200 to rotate and sleeve over the cup lid body 100. When the upper cover 200 is rotated, the flexible straw 300 is bent within the recess 110, achieving a seal and effectively preventing liquid leakage. This design requires only the rotation of the upper cover 200 to complete the sealing, making the operation very convenient. At the same time, the structural fitting between the sliding chute 120 and the first slider 220 not only ensures smooth rotation but also effectively prevents accidental detachment due to component deformation, making the connection more stable and reliable.

In other embodiments, referring to FIGS. 4 and 6, the side wall of the cup lid body 100 is provided with an annular boss 130. The side wall of the boss 130 is uniformly distributed with a plurality of lumps 131 along the circumferential direction, and the outer side of each lump 131 is provided with a sliding chute 120. By arranging the sliding chute 120 on the side of the lump 131, this layout not only avoids occupying space in other functional areas of the cup lid body 100 but also ensures the sliding chute 120 structure aligns more closely with the overall form, thereby achieving compact and orderly arrangement of components.

Meanwhile, referring to FIGS. 4 and 6, a plurality of first sliders 220 are disposed on the inner wall of the upper cover 200. Each first slider 220 is arc-shaped, and a plurality of notches 230 are formed between adjacent first sliders 220, matching the shape and size of the lumps 131 on the cup lid body 100. During installation, simply aligning the notches 230 of the upper cover 200 with the lumps 131 and pressing down allows the first sliders 220 to smoothly snap into the sliding chutes 120. This alignment design simplifies and speeds up the assembly process, significantly improving production efficiency.

This alignment design greatly enhances assembly efficiency. Additionally, the lumps 131 themselves reinforce the structural strength of the cup lid body 100, while placing the sliding chutes 120 on the sides of the lumps 131 ensures a tighter fit between the first sliders 220 and the sliding chutes 120, distributing force more evenly. This not only guarantees smooth rotation of the upper cover 200 but also effectively prevents structural loosening from long-term use, ensuring long-term connection stability.

In other embodiments, referring to FIG. 3, the flexible straw 300 bulges toward the cup lid body 100 and is provided with an annular groove 310. When the upper cover 200 is installed in place, the annular groove 310 is roughly flush with the surface of the upper cover 200. When the upper cover 200 is rotated, the edge of its through hole 210 presses against the annular groove 310. This structure ensures the flexible straw 300 bends stably and consistently at the predetermined position, effectively preventing sealing failure due to bending point deviation. At the same time, forced bending fully flattens the straw channel, reliably blocking liquid flow and significantly improving sealing performance.

Additionally, referring to FIGS. 3 and 4, a supporting strip 112 is provided at the bottom of the recess 110, corresponding to the edge of the through hole 210. When the upper cover 200 rotates, causing the flexible straw 300 to bend, the annular groove 310 portion of the straw will press against the supporting strip 112. The supporting strip 112 serves as a mechanical pivot point for the straw's bending, concentrating compressive forces to further tighten the bent section of the straw, filling any potential micro-gaps, thereby significantly enhancing the liquid barrier capability of the sealing interface. Compared to sealing solutions relying solely on the straw's own deformation, this supporting structure effectively prevents leakage due to insufficient bending, greatly improving the stability and reliability of the seal and ensuring no accidental liquid leakage.

In this embodiment, referring to FIGS. 4 and 6, a first limiting block 140 is provided on the cup lid body 100. Correspondingly, the upper cover 200 has an arc-shaped first guide rail 240 on its side that fits against the cup lid body 100, and the first limiting block 140 slides and is engaged within this guide rail. When the upper cover 200 rotates relative to the cup lid body 100, the first limiting block 140 slides along the first guide rail 240.

The first limiting block 140 on the cup lid body 100 and the arc-shaped first guide rail 240 of the upper cover 200 form a sliding fit. This structure confines the rotation trajectory of the upper cover 200 within the guide rail, effectively preventing radial deviation or axial detachment during rotation, fundamentally ensuring the stability of their connection and reducing the risk of misalignment-related failures.

It should be noted that in this embodiment, the first limiting block 140 is spherical in shape, while in other embodiments, it may adopt other specific shapes.

In other embodiments, referring to FIGS. 4 and 6, first limiting slots 250 are provided on both sides of the first guide rail 240, sized to match the first limiting block 140. When the upper cover 200 rotates to a specific position, the first limiting block 140 slides and snaps into the corresponding first limiting slot 250, achieving positioning and fixation. This positioning mechanism is designed to synchronize with the state of the flexible straw 300: when the first limiting block 140 snaps into one side's first limiting slot 250, the straw is fully extended for drinking; when it snaps into the other side, the straw is fully bent for sealing. This design ensures a one-to-one correspondence between functional states and operational positions, eliminating the need for repeated user adjustments and significantly enhancing operational certainty and usage reliability.

In this embodiment, please refer to FIGS. 4 and 6. The top surface of the cup lid body 100 is equipped with a silicone socket 150, which penetrates through the cup lid body 100. This structure provides an alternative drinking channel besides the flexible straw 300: users can insert a thin straw through the silicone socket 150 into the cup as needed, enhancing usage flexibility. Meanwhile, the silicone socket 150 itself features self-sealing properties, remaining closed when no straw is inserted, effectively preventing liquid leakage from this position. Thus, without compromising sealing reliability, the product gains a backup drinking method.

In other embodiments, please refer to FIGS. 4 and 6. The side of the upper cover 200 that fits with the cup lid body 100 is equipped with a second guide rail 260, and the silicone socket 150 on the cup lid body 100 is slidably mounted within the second guide rail 260. When the upper cover 200 rotates, the silicone socket 150 slides along the second guide rail 260. This design primarily provides a dedicated motion clearance space for the silicone socket 150, fundamentally preventing interference with the upper cover 200 and ensuring smooth rotation. Secondly, the second guide rail 260 works in coordination with the first guide rail 240 to jointly constrain the movement of the upper cover 200, forming a complementary guidance system that effectively suppresses deviation and wobbling during rotation, thereby enhancing operational stability.

In this embodiment, please refer to FIGS. 3 and 6. The center of the side where the upper cover 200 fits with the cup lid body 100 is equipped with a rotating shaft 270, while the cup lid body 100 features a first shaft hole 160, with the rotating shaft 270 positioned within the first shaft hole 160.

The cooperation between the rotating shaft 270 and the first shaft hole 160 provides a central pivot point for the rotation of the upper cover 200, ensuring that the upper cover 200 rotates concentrically around the center of the cup lid body 100, effectively preventing eccentricity or deviation during rotation and making the rotational trajectory of the upper cover 200 more stable and smooth. At the same time, the central shaft connection structure strengthens the tightness of the connection between the upper cover 200 and the cup lid body 100, maintaining a stable positional relationship during relative rotation, reducing component wear caused by wobbling or misalignment, further ensuring the overall structural stability and improving usage reliability.

In other embodiments, referring to FIGS. 5 and 7, the cup lid body 100 is movably inserted with an inserting rod 170 on its side. One end of the inserting rod 170 extending into the cup lid body 100 is equipped with a bayonet 180. When the inserting rod 170 is fully inserted into the cup lid body 100, the rotating shaft 270 is positioned within the bayonet 180, which tightly secures the rotating shaft 270. At this point, through the tight engagement between the bayonet 180 of the inserting rod 170 and the rotating shaft 270, the rotation of the upper cover 200 can be stably restricted, forming a physical locking structure. This ensures that during non-use (e.g., when carrying), the upper cover 200 will not rotate accidentally, fundamentally preventing liquid leakage caused by unintended extension of the flexible straw 300. Additionally, the inserting rod 170 features a movable insertion design, allowing users to lock or unlock it simply by inserting or removing the rod, eliminating the need for complex operations. This balances both the stability of the locked state and the convenience of use, catering to diverse everyday scenarios.

In this embodiment, referring to FIGS. 1 and 2, the upper cover 200 is provided with a mark 280. The mark 280 clearly indicates the correspondence between the rotation direction of the upper cover 200 and the “open” or “closed” state of the cup lid. This eliminates the need for repeated trial-and-error or manual consultation, reducing confusion caused by unfamiliar operations. Moreover, guided by the mark 280, users can directly rotate the upper cover 200 in the indicated direction to switch between the sealed or open state of the lid, avoiding ineffective actions due to misjudgment and making the process more efficient and smooth.

In other embodiments, referring to FIGS. 1 and 2, the top surface of the cup lid body 100 is equipped with an indication plate 190, whose dimensions match the through hole 210 of the upper cover 200. When the upper cover 200 is rotated to fully retract the flexible straw 300 into the recess 110, the through hole 210 aligns perfectly with the indication plate 190, creating a visually seamless appearance.

This design provides users with a clear and intuitive feedback mechanism. When users rotate the upper cover 200 until they see a complete indication plate 190, they can confirm that the straw is fully retracted and sealed.

Referring to FIG. 8, the present disclosure also provides a new-type cup lid, comprising a cup lid body 100 and an upper cover 200, where the upper cover 200 is sleeved onto the cup lid body 100.

In this embodiment, referring to FIGS. 8 and 9, the cup lid body 100 is provided with an accommodation part, at the bottom of which an insertion hole 111 is opened. A straw component is installed within the insertion hole 111. Meanwhile, the surface of the upper cover 200 features an opening part. When the upper cover 200 is sleeved onto the outer surface of the cup lid body 100, the straw component can extend through the opening part for ease of use.

It should be noted that in this embodiment, the accommodation part is the recess 110, the opening part is the through hole 210, and the straw component is the flexible straw 300.

In this embodiment, referring to FIGS. 15 and 16, the upper cover 200 consists of a locking ring 410 and a cover plate 420. The top surface of the locking ring 410 extends inward to form an extension end 411, while the bottom of the outer side of the cover plate 420 is fixed with an annular clamping plate 421. By rotatably mounting the clamping plate 421 onto the bottom of the extension end 411, the cover plate 420 can rotate relative to the locking ring 410.

The locking ring 410 and the cover plate 420 adopt a modular split design, allowing them to be quickly separated for independent deep cleaning or targeted maintenance.

Here, the locking ring 410 is fixed to the outer side of the cup lid body 100 through threads, while the cover plate 420 is rotatably installed on the top surface of the cup lid body 100.

The rigid fixation of the locking ring 410 provides a stable reference platform for the rotation of the cover plate 420, effectively preventing the entire upper cover 200 from loosening during rotation. This design decouples the functions of load-bearing connection and rotational friction, avoiding thread wear due to frequent rotation, thereby enhancing the product's long-term reliability and durability.

In other embodiments, referring to FIGS. 10 and 15, the top surface of the cup lid body 100 is equipped with a third guide rail 500, and the bottom of the cover plate 420 is fixed with a second slider 422, which is assembled into the third guide rail 500. The cooperation between the second slider 422 and the third guide rail 500 not only provides smooth guidance for the rotation of the cover plate 420 but also mechanically defines the start and end points of its rotation range. When the cover plate 420 rotates to one end (minimum), the flexible straw 300 is fully retracted into the recess 110; when rotated to the other end (maximum), the straw is fully extended.

The third guide rail 500 provides a stable path for the movement of the second slider 422, converting the rotational motion of the cover plate 420 into smooth linear guidance, eliminating jamming and wobbling, and ensuring a seamless operational feel.

In other embodiments, referring to FIGS. 9, 10, and 15, the top surface of the cup lid body 100 is fixed with a second limiting block 600, while the bottom of the cover plate 420 is symmetrically provided with two second limiting slots 423, corresponding to the two ends of the third guide rail 500's range. When the cover plate 420 rotates to the end of its range (maximum or minimum), the second limiting block 600 snaps into the corresponding second limiting slot 423. This structure clearly signals to the user, through an audible click and tactile feedback, that the flexible straw 300 has reached either the fully extended or fully retracted state.

It should be noted that the second limiting block 600 is spherical or of another specific shape.

In other embodiments, referring to FIGS. 9, 10, and 15, a rotary cylinder 424 is fixedly installed at the center of the cover plate 420, while the central part of the top surface of the cup lid body 100 is provided with a second shaft hole 425, with the rotary cylinder 424 located within the second shaft hole 425.

The cooperation between the rotary cylinder 424 and the second shaft hole 425 provides a central pivot point for the rotation of the cover plate 420, ensuring that the cover plate 420 can rotate concentrically around the center of the cup lid body 100, effectively preventing eccentricity or deviation during rotation and making the rotational trajectory of the cover plate 420 more stable and smooth. At the same time, the central shaft connection structure enhances the tightness of the connection between the cover plate 420 and the cup lid body 100, maintaining a stable positional relationship during relative rotation, reducing component wear caused by shaking or misalignment, further ensuring the overall structural stability and improving usage reliability.

In this embodiment, referring to FIGS. 11 and 12, the top surface of the cup lid body 100 is provided with a fixing groove 700, inside which a spring-loaded lid 710 is slidably installed. The size of the spring-loaded lid 710 matches the through hole 210 of the upper cover 200. The bottom of the spring-loaded lid 710 is equipped with a button snap mechanism 720. When the flexible straw 300 is fully retracted, pressing the spring-loaded lid 710 causes the mechanism to eject and lock into the through hole 210, thereby forming a mechanical stop for the cover plate 420 and effectively preventing the cover plate 420 from rotating due to accidental contact.

In other embodiments, referring to FIGS. 11, 13, and 14, the specific structure of the button snap mechanism 720 is as follows: the bottom of the spring-loaded lid 710 is rotatably fitted with a rotating rod 721, while the inner bottom wall of the fixing groove 700 is fixed with a first spring 722. The upper end of the first spring 722 is connected to a fixing cylinder 723, which is provided with a plurality of first supporting rods 724 with inclined surfaces at their tops on the side facing the rotating rod 721. Correspondingly, the rotating rod 721 is equipped with a plurality of second supporting rods 725, also featuring inclined top surfaces.

When the user first presses the spring-loaded lid 710, the rotating rod 721 rotates, causing the inclined top of the first supporting rod 724 to slide into the gap between two adjacent second supporting rods 725. This action forces the rotating rod 721 and the fixing cylinder 723 to move closer to each other, compressing the first spring 722, which results in the overall descent of the spring-loaded lid 710, causing it to exit the through hole 210. The upper cover 200 is then unlocked, allowing the user to rotate it. When the user presses the spring-loaded lid 710 again, the rotating rod 721 rotates once more. This time, the inclined surface of the first supporting rod 724 interacts with the inclined surface of the second supporting rod 725. Under the restoring force of the first spring 722, the spring-loaded lid 710 is pushed upward as a whole, returning to its initial position, where it re-enters the through hole 210, thereby limiting the movement of the upper cover 200 and preventing it from rotating.

The button snap mechanism 720 provides a clear “click” sound and tactile feedback, serving as definitive confirmation of state switching. More importantly, this bistable characteristic ensures that the spring-loaded lid will not accidentally open or close due to minor impacts or vibrations, fundamentally preventing misuse and guaranteeing absolute reliability of the locking function. At the same time, users do not need to learn complex operations—a simple “press” triggers all the intricate internal movements, achieving “one-click” convenience for locking and unlocking, significantly enhancing the product's ease of use and the smoothness of the user experience.

In other embodiments, as shown in FIGS. 9, 10, and 15, an outer cylinder 730 is fixed to the inner wall of the fixing groove 700, enclosing the internal rotating rod 721 and fixing cylinder 723. This structure provides stable movement tracks and external protection for the internal components, effectively shielding them from dust and foreign objects.

In other embodiments, as shown in FIG. 12, a protrusion 740 is provided on the inner wall of the fixing groove 700, while a plurality of hook plates 711 are fixed to one side of the spring-loaded lid 710. When the spring-loaded lid 710 moves to the pop-up position, the hook plates 711 engage with the protrusion 740, forming a lock that prevents the spring-loaded lid 710 from over-extending.

In this embodiment, as shown in FIGS. 15 and 16, the cover plate 420 has an accommodation cavity 426 on its top surface, and the upper cover 200 is additionally equipped with a detachable handle 430. The handle 430 connects to the accommodation cavity 426 on the cover plate 420 through an accommodation plate 431 on one side. This design allows users to grip and rotate the cover plate 420 more effortlessly using the handle 430. Additionally, the detachable feature of the handle 430 enables it to be cleaned separately, ensuring thorough hygiene.

Please refer to FIG. 17. The present disclosure also provides a new-type cup lid, which includes a cup lid body 100 and an upper cover 200. The upper cover 200 is sleeved onto the cup lid body 100.

In this embodiment, as shown in FIGS. 19 and 20, the outer surface of the cup lid body 100 is fixed with an annular raised strip 800. The upper cover 200 is snapped onto the raised strip 800 through an annular embedding groove on its inner side, thereby achieving a rotational connection with the cup lid body 100.

In this embodiment, as shown in FIG. 18, the top of the cup lid body 100 is provided with a placement groove 900, and a circular truncated cone 910 is fixed at the bottom of the groove. A vertical groove 911 is opened at the center of the circular truncated cone 910, and a V-shaped fixing plate 920 is rotationally mounted on its inner wall. One end of the fixing plate 920 is fixed with a suction nozzle 921, and its bottom is connected to a telescopic hose 922, which extends downward through the cup lid body 100 to connect the suction nozzle with the interior of the cup.

In other embodiments, as shown in FIGS. 17 and 18, the surface of the upper cover 200 is provided with an opening 930. When the upper cover 200 is sleeved onto the outer surface of the cup lid body 100, the suction nozzle 921 can extend through the opening 930 for ease of use. Meanwhile, when the upper cover 200 is rotated, the suction nozzle 921 can be retracted inside the upper cover 200, avoiding contact with the exterior.

In this embodiment, as shown in FIGS. 18, 19, 20, and 21, a squeezing plate 940 is fixed to the inner wall of the upper cover 200, with its bottom surface designed as an inclined plane—higher at one end and lower at the other. The end of the fixing plate 920 away from the suction nozzle 921 is equipped with a squeezing rod 923, and a second spring 924 is installed at the bottom of the same end.

When the upper cover 200 is fitted onto the cup lid body 100 and the suction nozzle 921 extends out through the opening 930, the squeezing rod 923 initially contacts the higher end of the squeezing plate 940. As the user rotates the upper cover 200, the squeezing rod 923 gradually slides along the inclined surface toward the lower end. During this process, the squeezing rod 923 is guided downward by the inclined surface, compressing the second spring 924. Since the fixing plate 920 is rotationally mounted in the vertical groove 911, its end away from the suction nozzle 921 is pressed downward, causing the suction nozzle 921 to tilt upward simultaneously. When the squeezing rod 923 reaches the lowest point of the inclined surface, the lifting angle of the suction nozzle 921 reaches its maximum, enabling stepless height adjustment of the suction nozzle 921. In this operation, the user can effortlessly and steadily raise the suction nozzle to a comfortable angle with just one hand by rotating the upper cover 200, perfectly adapting to different drinking habits and liquid level changes in the cup—without requiring both hands or additional steps.

It should be noted that the inclined trajectory of the squeezing plate 940 matches the circumferential length of the opening 930. This ensures that throughout the entire effective rotational stroke of the upper cover 200, the squeezing rod 923 can maintain continuous contact with the squeezing plate 940 and slide smoothly, while restricting the lifting motion of the suction nozzle 921 within the permissible range of the opening 930, thereby avoiding movement interference with the edges of the opening 930.

In other embodiments, as shown in FIGS. 18, 19, 20, and 21, a third limiting block 950 is fixed on the inner bottom wall of the vertical groove 911, with its top surface in contact with the lower surface of the fixing plate 920 near the suction nozzle 921. When the squeezing rod 923 is disengaged from the squeezing plate 940, the squeezing rod 923 rebounds upward under the elastic restoring force of the second spring 924, driving the fixing plate 920 to rotate accordingly. Here, the third limiting block 950 effectively mechanically limits the end of the fixing plate 920 near the suction nozzle 921, preventing excessive rebound, reducing fatigue wear at the spring and pivot connection points, extending the mechanism's service life, and enhancing overall rigidity and operational safety during use.

In summary, the above description demonstrates that the present disclosure achieves the following technical effects:

This application synchronously drives the internal linkage mechanism through the single operation of rotating the upper cover 200, enabling the flexible straw 300 to be stably bent and effectively flattened at a preset position, thereby achieving reliable sealing and preventing liquid leakage. The design simplifies the sealing process of the cup lid into a simple rotational action, significantly improving ease of use. Additionally, the connection between the upper cover 200 and the cup lid body 100 is realized through the fitting of the sliding chute 120 and the slider, ensuring smoother rotation while effectively preventing accidental detachment due to deformation, thereby guaranteeing stable and durable overall connectivity.

In the description of the present disclosure, it should be appreciated that directional terms such as “front, rear, up, down, left, right”, “horizontal, vertical, perpendicular, horizontal” and “top, bottom” etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description. In the absence of a contrary explanation, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present disclosure; the directional terms “inside, outside” refer to the inside and outside relative to the contour of each component itself.

For the convenience of description, spatial relative terms such as “on . . . ”, “above . . . ”, “on the upper surface of . . .”, “upper” etc. may be used here to describe the spatial positional relationship of a device or feature with other devices or features as shown in the drawings. It should be appreciated that spatial relative terms are intended to encompass different orientations of the device in use or operation other than the orientation described in the drawings. For example, if the device in the drawing is inverted, the device described as “above other devices or structures” or “on other devices or structures” will subsequently be positioned as “below other devices or structures” or “under other devices or structures”. Thus, the exemplary term “above” can include both “above” and “below” orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here should be interpreted accordingly.

In addition, it should be noted that the use of terms such as “first”, “second” etc. to define components is for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning, and therefore should not be understood as limiting the scope of protection of the present disclosure.

The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modifications, equivalent replacements, improvements etc. made within the spirit and principles of the present disclosure should be included within the scope of protection of the present disclosure.
