Description

Technical Field

[0001] This utility model relates to the field of water containers, specifically to an inner plug and a cup. Background Technology

[0002] Currently, the inner stoppers of water cups on the market are usually fixed as a one-piece structure. Many corners inside the inner stopper cannot be cleaned, which can easily breed bacteria and affect the safety of users' drinking. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an inner plug and a cup, wherein the inner plug can be disassembled into multiple parts for easy cleaning of the inside of the inner plug.

[0004] A first aspect of this utility model provides an inner plug, which includes: an inner plug body having an outlet; a top cover assembly detachably disposed on the inner plug body and forming an outlet channel communicating with the outlet; and a valve assembly detachably disposed on the inner plug body for opening and closing the outlet.

[0005] The inner plug provided in this embodiment includes three parts: a separable inner plug body, a top cover assembly, and a valve assembly. This allows for easy cleaning of these three parts separately, cleaning the water outlet and water channel, resulting in good cleaning performance, preventing bacterial growth, and ensuring high safety for users' drinking water.

[0006] Furthermore, in some embodiments, the inner plug body has a receiving cavity for accommodating the top cover assembly, and the bottom wall of the inner plug body is provided with a mounting hole communicating with the receiving cavity; a part of the valve assembly can extend into the receiving cavity through the mounting hole and cooperate with the top cover assembly, and the valve assembly can also be completely disengaged from the mounting hole from below.

[0007] In these embodiments, the valve assembly can open and close the outlet under the action of the upper cover assembly, making operation convenient. Furthermore, the valve assembly can be detached entirely from the mounting hole from below, and thus from the inner plug body, facilitating disassembly and assembly.

[0008] Furthermore, in some embodiments, the bottom wall of the inner plug body has an upwardly protruding connecting cylinder, the radial inner sidewall of the connecting cylinder forming a mounting hole, and the valve assembly is threaded or snap-fitted to the radial inner sidewall of the connecting cylinder.

[0009] In these embodiments, a portion of the valve assembly extends into the connecting cylinder and connects to the radial inner wall of the connecting cylinder. This facilitates a stable connection of the valve assembly to the inner plug body, preventing significant horizontal movement. Furthermore, the connection structure is simple, easy to manufacture, and convenient to assemble and disassemble.

[0010] Furthermore, in some embodiments, the top cover assembly is threaded or snap-fitted to the radially outer or radially inner wall of the connecting cylinder. This allows the connecting cylinder to connect to both the top cover assembly and the valve assembly, with all connection structures integrated onto the connecting cylinder. This results in a compact structure, a rational internal space layout for the inner plug, and a smaller inner plug size.

[0011] Furthermore, in some embodiments, one of the radial inner wall of the connecting cylinder and the outer peripheral surface of the valve assembly is provided with a snap fastener, and the other is provided with a groove adapted to the snap fastener. The valve assembly and the radial inner wall of the connecting cylinder are rotatably connected by the snap fastener and the groove. The structure is simple, easy to process, and easy to assemble and disassemble.

[0012] Furthermore, in some embodiments, when the upper cover assembly is mounted on the inner plug body, the upper cover assembly can prevent the valve assembly from detaching from the inner plug body; when the upper cover assembly detaches from the inner plug body, the valve assembly can be completely removed from the mounting hole from below. This prevents the valve assembly from accidentally falling off, as the upper cover assembly must be removed first before the valve assembly can be removed when disassembling the inner plug.

[0013] Furthermore, in some embodiments, the valve assembly includes: a mounting base detachably connected to the bottom wall of the inner plug body; and a valve core assembly integrated on the mounting base, the top of which can extend into the receiving cavity through a mounting hole to cooperate with the upper cover assembly, and the bottom of which can open and close the outlet from below under the action of the upper cover assembly.

[0014] In these embodiments, the main body of the valve assembly is integrated on the mounting base. The valve assembly can be disassembled as a whole by removing the mounting base from the inner plug body. This allows the valve assembly to be disassembled and assembled in one step, making the operation convenient.

[0015] Furthermore, in some embodiments, at least a portion of the mounting base extends into the mounting hole and is detachably connected to the inner wall of the mounting hole. If the entire mounting base extends into the mounting hole, the mounting base is compact, occupies little space, and helps to reduce the volume of the inner plug.

[0016] Furthermore, in some other embodiments, at least a portion is located below the inner plug body and extends to the outer periphery of the mounting hole, detachably connected to the lower end face of the outer periphery of the mounting hole. This design eliminates the need for a connecting structure within the limited space of the mounting hole to connect with the mounting base, and also eliminates the need to align the connecting structure within the mounting hole to achieve the connection with the mounting base. The connecting structure can be directly set on the lower end face around the mounting hole on the inner plug body, providing ample space for processing and assembly, making processing and assembly convenient.

[0017] Furthermore, in some embodiments, the inner plug body has a receiving cavity with an opening at the top, through which the upper cover assembly can extend into or exit the receiving cavity, and the cavity wall of the inner plug body surrounding the receiving cavity forms the channel wall of the water outlet channel. Thus, the upper cover assembly can be directly installed and removed from above the inner plug body, making installation and removal convenient.

[0018] Furthermore, in some embodiments, the top cover assembly includes: a top cover body, which is detachably connected to the inner plug body, and the top cover body has an mounting cavity that extends axially along the inner plug; a button, which is movably disposed in the mounting cavity; and a ratchet mechanism, which is disposed in the mounting cavity and cooperates with the button and the valve assembly respectively, so that the button can drive the valve assembly to open and close the outlet via the ratchet mechanism.

[0019] In these embodiments, users can easily open and close the water outlet by pressing a button, which, via a ratchet mechanism, drives the valve assembly. Furthermore, both the button and the ratchet mechanism are mounted on the upper cover body, and the upper cover body is detachably connected to the inner plug body. This ensures a stable connection and allows the button and ratchet mechanism to be easily removed along with the upper cover body.

[0020] Furthermore, a stop portion protruding towards the centerline of the inner plug is provided on the side wall of the cavity surrounding the mounting cavity of the upper cover body. The stop portion is used to stop and limit the ratchet mechanism from below. In this way, after the upper cover assembly is separated from the inner plug body, the stop portion can be used to block the ratchet mechanism, preventing the ratchet mechanism from falling off and being lost due to the disassembly of the upper cover assembly.

[0021] A second aspect of this utility model provides a cup, which includes a cup body and an inner plug as described in any of the above embodiments, the inner plug being disposed at the top opening of the cup body.

[0022] The cup provided in this embodiment has the beneficial effects of any of the above embodiments due to the inner plug of any of the above embodiments, which will not be described again here.

[0023] Other aspects and / or advantages of the present invention will be set forth in part in the description which follows, and in part will be clear from the description or may be learned by practice of the present invention. Attached Figure Description

[0048] The following will combine Figures 1 to 11 The present invention describes an embodiment of the inner plug and a cup.

[0049] like Figures 1 to 5 As shown, a first aspect of the present invention provides an inner plug, the inner plug comprising: an inner plug body 10, on which an outlet 110 is provided; an upper cover assembly 20, detachably disposed on the inner plug body 10 and forming an outlet channel 150 communicating with the outlet 110; and a valve assembly 30, detachably disposed on the inner plug body 10, for opening and closing the outlet 110.

[0050] The inner plug provided in this embodiment includes three parts: a separable inner plug body 10, a top cover assembly 20, and a valve assembly 30. This allows for easy cleaning of these three parts separately, cleaning the water outlet 110 and the water outlet channel 150, preventing bacterial growth, and ensuring high safety for users' drinking water.

[0051] Regarding the method of assembling and disassembling the valve assembly 30, further, in some embodiments, such as Figure 1 and Figure 2As shown, the bottom wall of the inner plug body 10 is provided with a mounting hole 120 that communicates with the receiving cavity 140; a part of the valve assembly 30 can extend into the receiving cavity 140 through the mounting hole 120 and cooperate with the upper cover assembly 20, so that the valve assembly 30 can open and close the outlet 110 under the action of the upper cover assembly 20. The valve assembly 30 can also be completely disengaged from the mounting hole 120 from below, and then disengaged from the inner plug body 10.

[0052] This design allows the valve assembly 30 to open and close the outlet 110 under the action of the upper cover assembly 20, making operation convenient. Furthermore, it allows the entire valve assembly 30 to detach from the inner plug body 10 through the mounting hole 120, facilitating easy assembly and disassembly.

[0053] Furthermore, in some embodiments, such as Figure 1 and Figure 8 As shown, the bottom wall of the inner plug body 10 has an upwardly protruding connecting cylinder 130. The radial inner sidewall of the connecting cylinder 130 forms a mounting hole 120. The outer peripheral surface of the valve assembly 30 is detachably connected to the radial inner sidewall of the connecting cylinder 130. The connecting cylinder 130 can act as a limiter, which helps the valve assembly 30 to be stably connected to the inner plug body 10, and prevents it from moving significantly in the horizontal direction.

[0054] Furthermore, such as Figure 1 As shown, the upper cover assembly 20 can also be detachably connected to the radially outer or radially inner wall of the connecting cylinder 130. For example, the upper cover body 210 of the upper cover assembly 20 can be threaded or snap-fitted to the connecting cylinder 130. In this way, the connecting cylinder 130 is connected to both the upper cover assembly 20 and the valve assembly 30, with all connection structures integrated on the connecting cylinder 130. This results in a compact structure, a reasonable internal space layout for the inner plug, and a smaller inner plug size.

[0055] For example, valve assembly 30 can be threaded or snap-fitted to the radial inner wall of connecting cylinder 130. Cover assembly 20 can also be threaded or snap-fitted to the radial outer wall of connecting cylinder 130.

[0056] Furthermore, in some embodiments, when the upper cover assembly 20 is mounted on the inner plug body 10, the upper cover assembly 20 can prevent the valve assembly 30 from detaching from the inner plug body 10; when the upper cover assembly 20 detaches from the inner plug body 10, the valve assembly 30 can be completely removed from the mounting hole 120 from below. Thus, when disassembling the inner plug, the upper cover assembly 20 must be removed first before the valve assembly 30 can be removed, preventing the valve assembly 30 from accidentally falling off.

[0057] Of course, in other embodiments, the disassembly and assembly of the upper cover assembly 20 and the valve assembly 30 can be carried out independently without any order, making disassembly and assembly convenient. Specifically, it can be determined according to the connection method between the upper cover assembly 20 and the inner plug body 10, and the connection method between the valve assembly 30 and the inner plug body 10.

[0058] In a specific embodiment, such as Figure 2 and Figure 8 As shown, the lower end of the mounting cavity 211 of the upper cover body 210 has a first connecting thread, and the connecting cylinder 130 has a second connecting thread. The upper cover body 210 and the inner plug body 10 are connected by the first connecting thread and the second connecting thread. The first connecting thread can be an internal thread, as shown, and the second connecting thread can be an external thread. This allows the upper cover assembly 20 and the valve assembly 30 to be connected inside and outside the connecting cylinder, respectively, resulting in a compact structure, a reasonable internal space layout for the inner plug, and a smaller inner plug size. Alternatively, the first connecting thread can also be an external thread, and the second connecting thread can be an internal thread.

[0059] The connection between the upper cover assembly 20 and the inner plug body 10 allows the upper cover body 210 to be directly screwed on when the upper cover assembly 20 is installed or removed, without having to worry about the valve assembly 30 that is in contact with it. The upper cover assembly 20 can be directly disassembled.

[0060] In a specific embodiment, such as Figures 2 to 7 As shown, a snap fastener 121 is provided on the outer peripheral surface of the valve assembly 30 and the radial inner wall of the connecting cylinder 130, and a groove 312 adapted to the snap fastener 121 is provided on the other. The mounting base 310 and the radial inner wall of the connecting cylinder 130 are rotatably connected by the snap fastener 121 and the groove 312. The structure is simple and easy to process.

[0061] like Figure 3 , Figure 4 and Figure 5As shown, the slot 312 may include a vertically extending first slot, a horizontally extending second slot, and a vertically extending third slot connected in sequence. The first slot extends upward through the upper edge of the outer peripheral surface of the mounting base 310, forming the slot inlet of the slot 312. The third slot is parallel to the first slot and does not extend through the upper edge of the outer peripheral surface of the mounting base 310, forming the end of the slot 312. When installing the valve assembly 30, the slot inlet can be aligned with the position of the latch 121, and the mounting base 310 can be inserted into the mounting hole 120 from bottom to top, so that the latch 121 extends into the first slot. Then, the mounting base 310 is rotated horizontally to allow the latch 121 to enter the second slot. Then, the mounting base 310 is moved downward to allow the latch 121 to enter the third slot until the end, thus achieving a rotatable locking connection between the mounting base 310 and the mounting hole 120. Installation is convenient. Similarly, to remove the valve assembly 30 from the inner plug body 10, the mounting base 310 is moved in the reverse direction, causing the latch 121 to disengage from the first groove through the third and second grooves in sequence, allowing the valve assembly 30 to be moved downwards. Disassembly is convenient.

[0062] In this disassembly method, when disassembling the valve assembly 30, the valve assembly 30 needs to be moved upward first so that the buckle 121 moves downward along the slot 312 and disengages from the end of the slot 312. Therefore, the upper cover assembly 20 needs to be removed from the inner plug body 10 first to avoid the upper cover assembly 20 and the valve assembly 30 from being in contact and hindering the disassembly of the valve assembly 30.

[0063] In another specific embodiment, the mounting base 310 is threaded to the radial inner wall of the connecting cylinder 130. With this disassembly method, the disassembly of the valve assembly 30 can be performed independently of the disassembly of the upper cover assembly 20, without any specific order, making operation convenient. Furthermore, the threaded connection provides good waterproofing, preventing water from flowing into the inner plug body 10 through the gap between the mounting base 310 and the connecting cylinder 130.

[0064] Furthermore, in some embodiments, such as Figures 1 to 5 As shown, the valve assembly 30 includes: a mounting base 310, which is detachably connected to the bottom wall of the inner plug body 10; and a valve core assembly, which is integrated on the mounting base 310. The top of the valve core assembly can extend into the receiving cavity 140 through the mounting hole 120 to cooperate with the upper cover assembly 20, and the bottom of the valve core assembly can open and close the outlet 110 under the action of the upper cover assembly 20.

[0065] In these embodiments, the main body of the valve assembly 30 is integrated on the mounting base 310. The valve assembly 30 can be disassembled as a whole by removing the mounting base 310 from the inner plug body 10. The valve assembly 30 can be disassembled and assembled in one step, which is convenient.

[0066] Furthermore, such as Figure 1 and Figure 2As shown, the valve core assembly may include a valve stem 320, a valve cap 330, and an elastic element 340. A through hole 311 is provided on the mounting base 310, into which the valve stem 320 extends movably. The bottom of the valve stem 320 has a valve plate 321, which can open or close the outlet 110 from below. The valve cap 330 is disposed on the top of the valve stem 320. The elastic element 340 is supported between the mounting base 310 and the valve cap 330. The outer diameters of both the valve cap 330 and the elastic element 340 are smaller than the inner diameter of the mounting hole 120, allowing the valve stem 320 and the valve cap 330 to extend into or exit the receiving cavity 140 through the mounting hole 120.

[0067] Here, the elastic element 340 is supported between the mounting base 310 and the valve cap 330. Since the mounting base 310 is mounted on the fixed inner plug body 10, and the valve cap 330 is mounted on the valve stem 320, the elastic element 340 can apply an upward force relative to the inner plug body 10 to the valve stem 320. This facilitates the valve stem 320 driving the valve plate 321 to close the outlet 110, and facilitates the valve stem 320 to abut against the upper cover assembly 20. In addition, the outer diameters of both the valve cap 330 and the elastic element 340 are smaller than the inner diameter of the mounting hole 120. If the dimensions are inconsistent in the height direction, it is assumed that the maximum outer diameter is smaller than the inner diameter of the mounting hole 120. This facilitates the overall movement of the valve assembly 30 towards the valve plate 321 to disengage from the mounting hole 120, avoiding interference.

[0068] Alternatively, the valve cap 330 and the valve stem 320 can be fixedly connected and not disassembled, or the valve cap 330 and the valve stem 320 can be detachably connected. In this way, after the valve assembly 30 is disassembled as a whole, the parts of the valve assembly 30 can be separated for more thorough cleaning.

[0069] During installation, the valve stem 320 is first passed through the through hole 311 from bottom to top. Then, the elastic element 340 is fitted onto the portion of the valve stem 320 extending upwards from the through hole 311. Next, the valve cap 330 is installed on top of the valve stem 320, compressing the elastic element 340 so that both ends of the elastic element 340 are supported between the valve cap 330 and the mounting base 310. This ensures that the elastic element 340 consistently applies an upward force to the valve stem 320. Finally, the mounting base 310 is connected to the inner plug body 10, thus assembling the valve assembly 30 and the inner plug body 10. For disassembly, simply separating the mounting base 310 from the inner plug body 10 allows the entire valve assembly 30 to be disassembled.

[0070] In addition, a connection structure that connects to the inner plug body 10 can be provided on the mounting base 310. For example, the aforementioned slot 312 can be provided on the outer peripheral surface of the mounting base 310 to achieve connection with the connecting cylinder 130.

[0071] Furthermore, at least a portion of the mounting base 310 extends into the mounting hole 120 and is detachably connected to the inner wall of the mounting hole 120. If the entire mounting base 310 extends into the mounting hole 120, the mounting base 310 is compact and occupies little space, which helps to reduce the volume of the inner plug.

[0072] Of course, the mounting base 310 can also extend partially into the mounting hole 120, with the through hole 311 provided on the portion of the mounting base 310 extending into the mounting hole 120, and the other portion extending to the outer periphery of the mounting hole 120, fitting against the lower end face of the outer periphery of the mounting hole 120. In this way, the valve assembly 30 and the inner plug body 10 are both limited in the horizontal and vertical directions, ensuring a stable connection of the valve assembly 30.

[0073] Alternatively, the portion of the mounting base 310 extending out of the mounting hole 120 can be detachably connected to the inner plug body 10. For example, at least a portion of the mounting base 310 can be located below the inner plug body 10 and extend to the outer periphery of the mounting hole 120, detachably connected to the lower end face of the outer periphery of the mounting hole 120. A through hole 311 is provided on the portion of the mounting base 310 opposite to the mounting hole 120. This design eliminates the need for a connecting structure within the relatively small mounting hole 120 to connect to the mounting base 310, and also eliminates the need to align the connecting structure within the mounting hole 120 for connection. The connecting structure can be directly positioned on the lower end face around the mounting hole 120 on the inner plug body 10, providing greater machining and assembly space, and facilitating both machining and assembly. Specifically, the mounting base 310 and the inner plug body 10 can be connected using bolts, clips, or other connecting components, which are not detailed here.

[0074] Regarding the specific structure of valve assembly 30, further, as... Figure 6 As shown, the upper surface of the mounting base 310 may be provided with an annular limiting groove 313, and the bottom of the elastic element 340 extends into the annular limiting groove 313; or the upper surface of the mounting base 310 may be provided with an annular rib, and the bottom of the elastic element 340 is fitted around the outer periphery of the annular rib. This can prevent the elastic element 340 from moving horizontally, thereby facilitating the accurate and stable support of the elastic element 340 for the valve stem 320 to move along the set path, and thus ensuring that the valve assembly 30 accurately opens and closes the outlet 110.

[0075] Furthermore, such as Figure 6 As shown, the valve assembly 30 also includes a first seal 350, which is fitted onto the valve stem 320 and abuts against the inner wall of the through hole 311. The first seal 350 prevents water from entering the inner plug through the gap between the valve stem 320 and the through hole 311.

[0076] As an example, such as Figure 6 As shown, the first sealing element 350 can be a sealing ring, which is fitted onto the valve stem 320.

[0077] Furthermore, the valve assembly 30 also includes a second seal (not shown) sandwiched between the mounting base 310 and the inner plug body 10 to seal the gap between the mounting hole 120 and the mounting base 310. The second seal prevents water from entering the interior of the inner plug body 10 through the gap between the mounting base 310 and the inner plug body 10.

[0078] As an example, if the entire mounting base 310 extends into the mounting hole 120, the second seal can be a sealing ring, fitted onto the mounting base 310. For instance, an annular mounting groove can be provided on the outer circumferential surface of the mounting base 310 to accommodate the sealing ring. If a portion of the mounting base 310 extends out of the mounting hole 120 and fits against the lower end face of the outer circumference of the mounting hole 120, the second seal can be a sealing sheet, sandwiched between the lower end face of the outer circumference of the mounting hole 120 and the mounting base 310.

[0079] Of course, in some other embodiments, the valve assembly 30 may not have a mounting base 310. In this case, for the detachable configuration of the valve assembly 30 and the inner plug body 10, in further embodiments, the valve assembly 30 includes a valve stem 320, a valve cap 330, and an elastic member 340. The inner plug body 10 is provided with a mounting hole 120, the valve stem 320 extends movably into the mounting hole 120, and the bottom of the valve stem 320 has a valve plate 321 for opening or closing the outlet 110; the valve cap 330 is detachably located on top of the valve stem 320, the outer diameter of the valve cap 330 is larger than the inner diameter of the mounting hole 120, and the valve cap 330 is exposed when the upper cover assembly 20 is removed from the inner plug body 10; the elastic member 340 is supported between the inner plug body 10 and the valve cap 330.

[0080] Here, the outer diameter of the valve cap 330 is larger than the inner diameter of the mounting hole 120, and the elastic element 340 is supported between the inner plug body 10 and the valve cap 330, which can prevent the valve assembly 30 from easily falling out of the mounting hole 120. When disassembling the valve assembly 30, the upper cover assembly 20 can be separated from the inner plug body 10 first, exposing the valve cap 330. Then, the valve cap 330 can be separated from the valve stem 320, the elastic element 340 can be removed, and then the valve stem 320 can be disengaged from the mounting hole 120 from below. This allows for the disassembly of the valve assembly 30 and the inner plug assembly. Moreover, the detachability of each part of the valve assembly 30 facilitates the cleaning of each component.

[0081] As an example, the valve cap 330 can be threaded or snap-fitted to the valve stem 320.

[0082] Regarding the method of assembling and disassembling the upper cover assembly 20, further, in some embodiments, such as Figure 1 , Figure 2 and Figure 8As shown, the inner plug body 10 has a receiving cavity 140 with an opening at the top. The upper cover assembly 20 can extend into or exit the receiving cavity 140 through the opening, and the cavity wall of the inner plug body 10 surrounding the receiving cavity 140 forms the channel wall of the water outlet channel 150. The water outlet 110 is located on the bottom wall of the inner plug body 10, corresponding to the position of the water outlet channel 150. In this way, the upper cover assembly can be directly installed and removed from the top of the inner plug body, making installation and removal convenient.

[0083] Regarding the specific structure of the upper cover assembly 20, further, in some embodiments, such as Figure 1 , Figure 2 , Figures 9 to 11 As shown, the upper cover assembly 20 includes: an upper cover body 210, which is detachably connected to the inner plug body 10, and an installation cavity 211 extending axially along the inner plug is provided inside the upper cover body 210; a button 220, which is movably disposed in the installation cavity 211; and a ratchet mechanism 230, which is disposed in the installation cavity 211 and cooperates with the button 220 and the valve assembly 30 respectively, so that the button 220 can drive the valve assembly 30 to open and close the outlet 110 via the ratchet mechanism 230.

[0084] In these embodiments, the user can press button 220 to drive valve assembly 30 to open and close outlet 110 via ratchet mechanism 230, which is convenient to operate. Moreover, both button 220 and ratchet mechanism 230 are set on the upper cover body 210, and the upper cover body 210 is detachably connected to the inner plug body 10. On the one hand, the two can be stably connected, and on the other hand, it is convenient to remove the upper cover assembly 20 as a whole.

[0085] Specifically, such as Figure 1 As shown, with both the upper cover assembly 20 and the valve assembly 30 assembled on the inner plug body 10, the top of the valve stem 320 abuts against the ratchet mechanism 230. Thus, when the user presses the button 220 once, the ratchet mechanism 230 can push the valve stem 320 downwards, causing the valve plate 321 to move away from the outlet 110, facilitating water flow out through the outlet 110 and the water outlet channel 150. When the user presses the button 220 a second time, the valve stem 320, under the elastic force of the elastic element 340, can push the ratchet mechanism 230 and the button 220 upwards to reset, causing the valve plate 321 to close the outlet 110.

[0086] Since the upper cover assembly 20 can be detached from the inner plug body 10, the ratchet mechanism 230 and the button 220 are likely to fall off and be easily lost. To solve this problem, furthermore, in some embodiments, such as Figure 1 , Figure 2 and Figure 9As shown, the upper cover body 210 has a stop portion 212 protruding towards the centerline of the inner plug on the cavity side wall of the mounting cavity 211. The stop portion 212 is used to stop and limit the ratchet mechanism 230 from below. In this way, after the upper cover assembly 20 is separated from the inner plug body 10, the stop portion 212 can be used to block the ratchet body 232, preventing it from falling out of the mounting cavity 211 and avoiding the ratchet mechanism 230 from falling out and being lost due to the disassembly of the upper cover assembly 20.

[0087] Furthermore, the stop part 212 can be an independent component assembled on the cavity sidewall of the mounting cavity 211, or the stop part 212 can be integrally formed with the cavity sidewall of the mounting cavity 211.

[0088] Specifically, the ratchet mechanism 230 can also be installed in the mounting cavity 211 through the lower opening, in which case the stop part 212 can be subsequently assembled in the mounting cavity 211. The ratchet mechanism 230 can also be installed in the mounting cavity 211 through the upper opening, in which case the stop part 212 can be integrally formed with the cavity sidewall of the mounting cavity 211 or assembled inside the mounting cavity 211.

[0089] Furthermore, such as Figure 1 and Figure 9 As shown, the stop portion 212 can be annular, so that it can block the ratchet mechanism 230 regardless of its rotation. Furthermore, the stop portion 212 can enclose a clearance hole 213, allowing the valve stem 320 to pass through the clearance hole 213 and engage with the ratchet mechanism 230. Here, the outer diameter of the valve cap 330 can be smaller than the inner diameter of the clearance hole 213, allowing the valve cap 330 to extend above the clearance hole 213 and easily disengage downwards from it.

[0090] As an example, the stop 212 is an integral rib protruding from the side wall of the mounting cavity 211 toward the centerline of the inner plug. It is easy to manufacture.

[0091] As an example, the stop portion 212 is an elastic stop ring that fits tightly against the inner wall of the mounting cavity 211.

[0092] Furthermore, in some embodiments, such as Figure 1 , Figure 10 and Figure 11As shown, the ratchet mechanism 230 may include a ratchet seat 231, a ratchet body 232, and a ratchet push rod 233. Here, the ratchet seat 231 is installed inside the mounting cavity 211, and can be disassembled synchronously with the upper cover body 210, preventing it from easily falling off. The ratchet body 232 and the ratchet push rod 233 are movably disposed within the hollow cavity of the ratchet seat 231, which extends axially along the inner plug. A guide structure is provided on the inner wall of the hollow cavity of the ratchet seat 231. The ratchet push rod 233 can extend into the hollow cavity of the ratchet seat 231 to cooperate with the ratchet body 232 and move along the guide structure. When the stop member limits the ratchet mechanism 230, the ratchet mechanism 230 maintains a guiding connection with the guide structure, preventing accidental displacement of the ratchet mechanism 230 and thus preventing transmission failure.

[0093] As an example, such as Figure 10 and Figure 11 As shown, on the outer peripheral surfaces of the guide structure and the ratchet push rod 233, one has a vertically extending guide groove 2311, and the other has a guide latch 2331 that mates with the guide groove 2311. The guide structure is simple in design and easy to manufacture.

[0094] like Figure 9 , Figure 10 and Figure 11 As shown, the bottom of the button 220 has an annular connecting cylinder 130. The ratchet push rod 233 is sleeve-shaped and fits around the outer periphery of the annular connecting cylinder 130, and is connected to the annular connecting cylinder 130 by a second buckle 2332. The lower end of the ratchet push rod 233 has a plurality of circumferentially distributed third ratchet teeth 2333. The ratchet body 232 includes a ratchet disc and a connecting rod connected to the middle of the ratchet disc. The connecting rod extends into the inner cavity of the ratchet push rod 233. The upper surface of the ratchet disc is provided with a plurality of circumferentially distributed second ratchet teeth 2321. The ratchet seat 231 is sleeve-shaped. The inner sidewall of the ratchet seat 231 is provided with a plurality of first ratchet teeth 2313 with their tips pointing downwards and circumferentially spaced. The first ratchet teeth 2313 can engage with the second ratchet teeth 2321, and a slot is formed between two circumferentially adjacent first ratchet teeth 2313.

[0095] When button 220 is pressed, it pushes ratchet push rod 233 downward. During this downward movement, the third ratchet tooth 2333 engages with the second ratchet tooth 2321, causing the ratchet body 232 to rotate downward while simultaneously rotating at a set angle for the first time. This pushes the second ratchet tooth 2321 below the first ratchet tooth 2313. Then, when button 220 is released, the spring in valve assembly 30 pushes valve stem 320 upward, which in turn pushes the ratchet tooth upward. The ratchet body 232 and the second ratchet 2321 will move upward and insert into the first ratchet 2313. With the cooperation of the first ratchet 2313, the ratchet body 232 rotates a second time at a set angle until it inserts into the root of the first ratchet 2313 and abuts against the first ratchet 2313. At this time, the first ratchet 2313 on the ratchet seat 231 can press down the valve rod 320 and the valve plate 321 through the ratchet body 232, so that the valve plate 321 moves down to open the water outlet 110, making it convenient for the user to drink water. When button 220 is pressed for the second time, button 220 pushes ratchet push rod 233 downward. During the downward movement of ratchet push rod 233, the third ratchet tooth 2333 will insert into the second ratchet tooth 2321 after the second rotation, pushing the ratchet body 232 to move downward while rotating a set angle for the third time, and separating the second ratchet tooth 2321 from the first ratchet tooth 2313. Then, when button 220 is released, the spring will push the valve stem 320 upward, and then push the ratchet body 232 upward, the third... After the second rotation, the second ratchet tooth 2321 on the ratchet body 232 will insert into the slot between two circumferentially adjacent first ratchet teeth 2313. The ratchet body 232 will then retract into the ratchet seat 231 until the second ratchet tooth 2321 abuts against the slot sidewall at the top of the slot, or the upper limit structure of the ratchet seat 231 restricts the ratchet body 232 or ratchet push rod 233 from moving upward. At this time, the spring can push the valve stem 320 upward and simultaneously pull the valve plate 321 upward to close the outlet 110. Here, the slot can be constructed as a guide groove 2311 to limit the ratchet push rod 233. Of course, a guide groove 2311 different from the slot can also be additionally provided on the ratchet seat 231.

[0096] Here, the ratchet seat 231 is a separate component, installed within the mounting cavity 211. Of course, in other embodiments, the ratchet seat 231 can also be integrally formed with the cavity wall of the mounting cavity 211. In this case, it is preferable that the remaining components of the ratchet mechanism 230 are installed in the mounting cavity 211 through the lower opening to avoid interference.
