Description

Technical Field

[0001] This utility model relates to a cup lid, and more particularly to a removable and cleanable push-button cup lid. Background Technology

[0002] The push-button principle has become the preferred method for opening and closing water bottle caps due to its ease of use. However, these push-button caps generally suffer from complex structures, as the push-button mechanism is fixed to the cap's body, making it difficult for users to disassemble and reassemble them themselves.

[0003] Crucially, if the contents of the cup have any adhering or sedimentary substances, residue can remain in the press-type lid's mechanism. The press-type mechanism has several complex parts, and these parts are confined within the lid's internal space, creating numerous blind spots for cleaning. Due to the difficulty in disassembling the lid, users cannot thoroughly clean the inside of the lid, making bottle cap cleaning a major problem that affects the user experience and poses potential hygiene risks. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a detachable and cleanable press-type cup lid. The device has a detachable structure between the press-type structure and the cup lid cylinder, making it convenient for users to remove the press-type structure from the cup lid cylinder for cleaning.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A removable and cleanable push-button cup lid includes a cylindrical body, a mounting base, a push-button assembly, and a push-button cap;

[0007] The mounting base is detachably mounted on the cylindrical body, the pressing component is mounted on the inner cavity of the cylindrical body via the mounting base, and the pressing cover is mounted on the pressing component;

[0008] The press cover has a press cover blocking structure in the elastic extension direction. When the press cover is raised, it abuts against the press cover blocking structure to form a closed state; when the press cover is lowered, it separates from the press cover blocking structure to form an open state.

[0009] Preferably, the mounting base includes a ring portion, a connecting portion, and a central portion. The ring portion is circumferentially spaced around the outer ring of the central portion, and the ring portion and the central portion are integrally connected by the connecting portion. The pressing component is mounted on the central portion.

[0010] Preferably, it also includes a sliding groove, which is vertically disposed within the circumference of the annular portion;

[0011] The pressing cover is provided with a sliding block that extends out of the circumference and is slidably installed in the sliding groove.

[0012] Preferably, the pressing component includes a lifting wheel, a locking cylinder, a lower guide component, and a compression spring;

[0013] The locking cylinder is fixed to the center, and the lifting wheel is slidably installed inside the locking cylinder. The locking cylinder is provided with low-position slots in a ring at intervals, and the intervals between the low-position slots are vertical release slots. Cam blocks are provided at intervals on the outer periphery of the lifting wheel, and the number and interval angle of the cam blocks are the same as those of the low-position slots.

[0014] The guide toothed disc of the lower guide assembly is fixed to the bottom of the locking cylinder. When the lifting wheel descends and engages with the guide toothed disc, the lifting wheel begins to rotate as it descends, so that the cam block corresponds to the upper low-position slot or release slot.

[0015] The compression spring is sleeved on the outer ring of the locking cylinder and the lifting wheel. The lifting wheel is axially rotatably mounted on the bottom surface of the pressing cover. The two ends of the compression spring are respectively pressed against the bottom surface and the center of the pressing cover.

[0016] Furthermore, the low-position slot is composed of two ratchet teeth that are connected to each other along the circumferential direction. The groove between the two ratchet teeth is the cam block constraint position, and the two outer sides of the two ratchet teeth are the release grooves.

[0017] The upper and lower parts of the cam block are inclined surfaces in the circumferential direction. The inclined surface of the upper part of the cam block faces the inclined surface of the ratchet of the low slot, and the inclined surface of the lower part of the cam block faces the inclined surface of the ratchet of the guide tooth plate.

[0018] The tip of the ratchet in the lower slot faces the inclined surface of the ratchet of the guide tooth disk below, and the tip of the ratchet of the guide tooth disk faces the inclined surface of the ratchet of the upper lower slot above. The ratchet of the lower slot and the ratchet of the guide tooth disk are oriented in the same direction in the circumferential direction.

[0019] Furthermore, the lower guide assembly includes a guide toothed disc and a mounting sleeve, the guide toothed disc being spaced apart at the center of the mounting sleeve, and the guide toothed disc and the mounting sleeve being integrally connected by a connecting structure;

[0020] The guide tooth disk has a ratchet structure. Multiple vertically arranged ratchet teeth on the guide tooth disk form a cylindrical annular ratchet guide structure, which corresponds to the cam block on the outer periphery of the lifting wheel.

[0021] Furthermore, the pressing cap blocking structure is an annular flange, which extends from the inner wall of the cylindrical body towards the center;

[0022] The press cover is equipped with a sealing ring, which is arranged around the circumference of the upper surface of the press cover. When the press cover is elastically raised, the sealing ring of the press cover abuts against the annular flange.

[0023] Furthermore, the inner wall of the cylindrical body is provided with a slot, and the side end of the mounting base is provided with a locking block corresponding to the slot. The cylindrical body and the mounting base constitute a rotating locking structure.

[0024] Furthermore, the cylindrical body is provided with threads on the outside.

[0025] Furthermore, the minimum distance between the ratchet teeth of the low-position slot and the ratchet teeth of the guide toothed plate is greater than the height of the cam block; the width of the release slot is greater than the width of the cam block.

[0026] The locking cylinder is positioned downwards from the plane of the annular portion, and the vertical sliding stroke of the sliding groove is less than the height of the locking cylinder.

[0027] When the pressing cover is in a blocked state relative to the cylindrical body, the cam block of the lifting wheel is accommodated in the release groove.

[0028] One of the above technical solutions includes the following beneficial effects: the detachable connection between the mounting base and the cylindrical body allows the push-button assembly and the press cap to be removed from the cylindrical body along with the mounting base, completely exposing the originally hidden internal structure. Compared to an integrated structure, users can rinse the disassembled individual components, such as the cylindrical body, the mounting base, and the push-button assembly and press cap installed on the mounting base, separately, preventing dirt from accumulating in the gaps and solving the problem of difficult cleaning inside the push-button cup lid.

[0035] The components include: cylindrical body 100, mounting base 200, pressing component 300, pressing cover 400, slot 110, ring part 210, connecting part 220, sliding groove 230, locking block 240, sliding block 410, lifting wheel 310, locking cylinder 320, lower guide component 330, compression spring 340, low position slot 350, release groove 360, cam block 370, guide gear plate 380, and mounting sleeve 390. Detailed Implementation

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] like Figure 1 and Figure 2 As shown, a removable and cleanable press-type cup lid is characterized by comprising a cylindrical body 100, a mounting base 200, a pressing component 300, and a pressing cover 400.

[0038] The mounting base 200 is detachably mounted on the cylindrical body 100, the pressing component 300 is mounted in the inner cavity of the cylindrical body 100 via the mounting base 200, and the pressing cover 400 is mounted on the pressing component 300.

[0039] The press cover 400 has a blocking structure in the elastic extension direction. When the press cover 400 is raised, it abuts against the blocking structure to form a closed state. When the press cover 400 is lowered, it separates from the blocking structure to form an open state.

[0040] The detachable connection between the mounting base 200 and the cylindrical body 100 allows the push-button assembly 300 and the press cap 400 to be removed from the cylindrical body 100 along with the mounting base 200, completely exposing the originally hidden internal structure. Compared to an integrated structure, users can rinse the disassembled individual components, such as the cylindrical body, the mounting base, and the push-button assembly and press cap installed on the mounting base, separately, preventing dirt from accumulating in the gaps and solving the problem of difficult cleaning inside the press-type cup lid; the diameter of the press cap 400 in this solution is smaller than that of the cylindrical body 100.

[0041] like Figure 2 As shown, the mounting base 200 includes a ring portion 210, a connecting portion 220, and a central portion. The ring portion 210 is circumferentially spaced around the outer ring of the central portion, and the ring portion 210 and the central portion are integrally connected through the connecting portion 220. The push assembly 300 is mounted on the central portion.

[0042] The push-button component 300 is mounted on the mounting base 200. The modular design facilitates disassembly by separating the mounting base 200 from the cylindrical body 100.

[0043] like Figure 2 As shown, it also includes a sliding groove 230, which is vertically disposed within the circumference of the annular portion 210;

[0044] The pressing cover 400 is provided with a sliding block 410 extending out of the circumference, and the sliding block 410 is slidably installed in the sliding groove 230.

[0045] The sliding block 410, in conjunction with the vertical sliding groove 230, provides a rigid guide for the lifting / lowering of the pressing cover 400, forcing the pressing cover 400 to move only in a straight line along the central axis of the cup lid, thus completely avoiding the problem of rotation and offset of the pressing cover 400 caused by uneven pressing force during the pressing process.

[0046] like Figure 3 , Figure 4 , Figure 5 and Figure 6 The push assembly 300 includes a lifting wheel 310, a locking cylinder 320, a lower guide assembly 330, and a compression spring 340;

[0047] like Figure 3 and Figure 5 and Figure 6 As shown, the locking cylinder 320 is fixed to the center, and the lifting wheel 310 is slidably installed inside the locking cylinder 320. The locking cylinder 320 is provided with low-position slots 350 in an annular pattern, and the spaced portions between the low-position slots 350 are vertical release slots 360. The outer periphery of the lifting wheel 310 is provided with cam blocks 370 at intervals, and the number and interval angle of the cam blocks 370 are the same as those of the low-position slots 350.

[0048] The guide toothed disc 380 of the lower guide assembly 330 is fixed to the bottom of the locking cylinder 320. When the lifting wheel 310 descends and engages with the guide toothed disc 380, the lifting wheel 310 begins to rotate as it descends, so that the cam block 370 corresponds to the upper low position slot 350 or release slot 360.

[0049] The compression spring 340 is sleeved on the outer ring of the locking cylinder 320 and the lifting wheel 310. The lifting wheel 310 is axially rotatably mounted on the bottom surface of the pressing cover 400. The two ends of the compression spring 340 are respectively pressed against the bottom surface and the center of the pressing cover 400.

[0050] The design of the lifting wheel 310 engaging and rotating with the guide gear 380 when it descends, combined with the correspondence between the cam block 370 and the low-position locking slot 350 or the release slot 360, allows for switching between open and closed states with a single press: In the closed state, the cam block 370 is located in the low-position locking slot 350. When pressed, the lifting wheel 310 descends and rotates, the cam block 370 rotates into the release slot 360, and the spring 340 rebounds, causing the entire assembly to rise, switching to the open state. In the open state, the cam block 370 is located in the release slot 360. When pressed again, the lifting wheel 310 descends and rotates, the cam block 370 rotates into the low-position locking slot 350, and after being released, it is locked by the low-position locking slot 350, maintaining the closed state. This achieves the switching between the closed and open states of the press cover 400.

[0051] like Figure 3 and Figure 6 As shown, the low-position slot 350 is composed of two ratchet teeth that are connected to each other along the circumferential direction. The groove between the two ratchet teeth is the constraint position of the cam block 370, and the two outer sides of the two ratchet teeth are the release grooves 360.

[0052] The upper and lower parts of the cam block 370 are inclined surfaces in the circumferential direction. The inclined surface of the upper part of the cam block 370 faces the inclined surface of the ratchet of the low position slot 350, and the inclined surface of the lower part of the cam block 370 faces the inclined surface of the ratchet of the guide tooth plate 380.

[0053] The tip of the ratchet in the low slot 350 faces the inclined surface of the ratchet in the lower guide plate 380, and the tip of the ratchet in the guide plate 380 faces the inclined surface of the ratchet in the upper low slot 350. The ratchet in the low slot 350 and the ratchet in the guide plate 380 have the same orientation in the circumferential direction.

[0054] The upper and lower inclined surfaces of the cam block 370 correspond to the ratchet inclined surfaces of the low-position slot 350 and the guide gear plate 380, respectively, so that the axial force during pressing can be smoothly converted into rotational force through the contact of the inclined surfaces. When the lifting wheel 310 is pressed down, the lower inclined surface of the cam block 370 contacts the ratchet inclined surface of the guide gear plate, and the axial pressure is decomposed into a circumferential component along the inclined surface, driving the lifting wheel 310 to rotate naturally; when it is raised, the upper inclined surface of the cam block 370 fits against the ratchet inclined surface of the low-position slot, and the spring return force guides the lifting wheel to rotate to the corresponding position through the inclined surface, ensuring functional stability with the self-guiding and self-locking characteristics of the mechanical structure.

[0055] like Figure 6 As shown, the lower guide assembly 330 includes a guide toothed disc 380 and a mounting sleeve 390. The guide toothed disc 380 is spaced apart at the center of the mounting sleeve, and the guide toothed disc 380 and the mounting sleeve are integrally connected by a connecting structure.

[0056] The guide tooth disk 380 has a ratchet structure. The multiple vertically arranged ratchets of the guide tooth disk 380 form a cylindrical annular ratchet guide structure, which corresponds to the cam block 370 on the outer periphery of the lifting wheel 310.

[0057] Rotational precision is ensured through full-circumferential constraint of the annular ratchet, stress stability is enhanced through an integrated frame structure, and the modular and open design is adapted to the needs of disassembly and cleaning.

[0058] like Figure 4 and Figure 5 As shown, the pressing cap 400 has an annular flange as its blocking structure, which extends from the inner wall of the cylindrical body 100 toward the center.

[0059] The press cover 400 is provided with a sealing ring, which is arranged around the circumference of the upper surface of the press cover. When the press cover 400 is elastically raised, the sealing ring of the press cover 400 abuts against the annular flange.

[0060] The combination design of the annular flange and the sealing ring mainly achieves the sealing effect between the press cap 400 and the cylindrical body 100.

[0061] like Figure 5 As shown, the inner wall of the cylindrical body 100 is provided with a slot 110, and the side end of the mounting base 200 is provided with a locking block 240 corresponding to the slot 110. The cylindrical body 100 and the mounting base 200 constitute a rotating locking structure.

[0062] The design of the slot in the cylindrical body 100 and the rotating snap-fit ​​structure of the mounting block 240 in the mounting base 200 enables convenient assembly and reliable fixation.

[0063] In addition, the cylindrical body 100 has threads on its exterior.

[0064] The threads are used for installation with the cup body.

[0065] As a supplement to the above technology, the minimum distance between the ratchet teeth of the low-position slot 350 and the ratchet teeth of the guide tooth disk 380 is greater than the height of the cam block 370; the width of the release slot 360 is greater than the width of the cam block 370.

[0066] The locking cylinder 320 is positioned downwards from the plane of the annular portion 210, and the vertical sliding stroke of the sliding groove 230 is less than the height of the locking cylinder 320.

[0067] When the pressing cover 400 is in a blocked state relative to the cylindrical body 100, the cam block 370 of the lifting wheel 310 is accommodated in the release groove 360.

[0068] The matching of the sliding groove stroke and the locking cylinder height is used to constrain the extreme position of the press cover; with the cam block 370 as the reference, the dimensional relationship is defined to ensure the coordinated movement of the mounting base 200, the pressing component 300 and the press cover 400.

[0069] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
