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] The top of the cup usually has an inner stopper, which includes a lower cover assembly and an upper cover assembly located inside the lower cover assembly. A water outlet channel is formed between the upper and lower cover assemblies, and the lower cover assembly has a water outlet that communicates with the water outlet channel. For convenient drinking, the upper cover assembly usually has a button, below which is a ratchet mechanism. Pressing the button rotates the ratchet body of the ratchet mechanism, opening and closing the water outlet. However, when the upper cover assembly is disassembled for cleaning, the ratchet mechanism is easily dislodged and lost. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an inner plug and a cup to at least solve the problem of ratchet mechanisms being easily dropped or lost.

[0004] A first aspect of this utility model provides an inner plug, which includes a lower cover assembly and an upper cover assembly detachably disposed within the lower cover assembly. A water outlet channel is formed between the lower cover assembly and the upper cover assembly. The upper cover assembly includes: an upper cover body, which has an installation cavity extending axially through the inner plug, and a stop portion protruding towards the centerline of the inner plug on the side wall of the installation cavity; and a ratchet mechanism that can be installed in the installation cavity through an upper opening and is stopped and limited from below by the stop portion.

[0005] The inner plug in this embodiment allows for the detachment of the upper and lower cover assemblies, facilitating the removal of the upper cover assembly for separate cleaning of both assemblies and the water outlet channel between them. This ensures drinking safety and prevents long-term liquid accumulation in the outlet channel, thus preventing bacterial growth or unpleasant odors. Furthermore, a stop is provided within the mounting cavity of the upper cover body. After the upper and lower cover assemblies are separated, the stop prevents the ratchet body from falling out of the mounting cavity, solving the problem of the ratchet mechanism falling out and being lost due to the removal of the upper cover assembly. Additionally, the ratchet mechanism is inserted into the mounting cavity from above, making installation convenient.

[0006] Furthermore, in some embodiments, the ratchet mechanism includes: a ratchet seat, installed within the mounting cavity, the ratchet seat having a hollow cavity extending axially along the inner plug; a ratchet body, movably disposed within the hollow cavity of the ratchet seat; and a ratchet push rod, movably disposed above the ratchet body and capable of driving the ratchet body to rotate; wherein, when the upper cover assembly and the lower cover assembly are separated, the ratchet body can fall and overlap the stop portion. Thus, designing an independent ratchet seat to cooperate with the ratchet body, compared to the related art where the ratchet seat and upper cover body are integrally formed, simplifies the structure of the upper cover body and facilitates its processing; furthermore, when installing the ratchet mechanism, the ratchet body and ratchet push rod can be installed into the mounting cavity first, and then the ratchet seat can be installed into the mounting cavity, ensuring that the ratchet mechanism can be installed into the mounting cavity from above and achieving mutual cooperation between the ratchet body and the ratchet seat.

[0007] Furthermore, in some embodiments, the stop portion is distributed circumferentially along the sidewall of the mounting cavity, and the inner diameter of the stop portion is smaller than the maximum outer diameter of the ratchet body. Thus, regardless of the angle to which the ratchet body rotates, when the top cover assembly is removed and the ratchet body falls, the stop portion can prevent the ratchet body from falling further, effectively preventing the ratchet body from being lost.

[0008] Furthermore, in some embodiments, the stop and the upper cover body are integrally formed. This facilitates processing and ensures good connection stability, which in turn allows the ratchet body to stably attach to the stop after it is lowered. Moreover, it eliminates the need for assembly of the stop, improving assembly efficiency.

[0009] Furthermore, in some embodiments, the cavity sidewall of the mounting cavity has an integrally protruding inward stop rib, which forms a stop portion; or the lower part of the cavity sidewall of the mounting cavity tapers inward to form a stepped surface on the inner side, which forms a stop portion. The stop portion has a simple structure and is easy to process.

[0010] Furthermore, in some embodiments, a guide structure is provided on the inner wall of the hollow cavity of the ratchet seat, and the ratchet push rod can extend into the hollow cavity of the ratchet seat to cooperate with the ratchet body and move along the guide structure; wherein, when the ratchet body overlaps on the stop, the ratchet push rod maintains the guiding connection with the guide structure.

[0011] In these embodiments, by moving the ratchet push rod along the guide structure, it is beneficial for the ratchet push rod to accurately push the ratchet body to rotate by a set angle, ensuring effective force transmission. After the upper cover assembly and the lower cover assembly separate, the ratchet body will slide onto the stop. At this time, keeping the ratchet push rod in a guiding connection with the guide structure can effectively prevent the ratchet push rod from rotating during the sliding process. Thus, after the upper cover assembly and the lower cover assembly are reassembled, when the valve assembly pushes the ratchet body again, the ratchet body can properly engage with the ratchet push rod, avoiding ratchet mechanism transmission failure caused by the reassembly of the upper cover assembly and the lower cover assembly.

[0012] Furthermore, in some embodiments, one of the guide structure and the outer peripheral surface of the ratchet push rod has a vertically extending guide groove, and the other has a guide protrusion that mates with the guide groove. The guide structure design is simple and easy to manufacture.

[0013] Furthermore, in some embodiments, the lower cover assembly includes an inner plug body and a valve assembly. The inner plug body is provided with an outlet communicating with the water outlet channel. The valve assembly is disposed on the inner plug body and can extend from the bottom into the mounting cavity to abut against and cooperate with the ratchet body. The upper cover assembly also includes a button, which is disposed on the top of the ratchet push rod. When the button is pressed repeatedly, the ratchet push rod can push the ratchet body to rotate, thereby alternately pushing the valve assembly to open and close the outlet.

[0014] In these embodiments, when a user needs to drink water, simply pressing the button will activate the ratchet mechanism to open the valve assembly, allowing water to flow out through the outlet and channel. This eliminates the need for the inner stopper to be fully open, making operation convenient. When drinking water is no longer needed, simply pressing the button again will rotate the ratchet, causing the valve assembly to reset and close the outlet under the spring's elasticity, thus improving the user experience.

[0015] Furthermore, in some embodiments, the ratchet seat is sleeve-shaped, and its outer periphery is connected to the side wall of the mounting cavity via a snap-fit ​​connection; and / or the bottom of the ratchet seat rests on the stop portion. This design allows the ratchet seat to be stably installed within the mounting cavity, preventing it from shifting vertically, thus facilitating accurate engagement with the ratchet body. Especially when the bottom of the ratchet seat rests on the stop portion, the ratchet seat can be directly inserted into the mounting cavity from the upper opening and received by the stop portion during installation, making installation convenient and quick.

[0016] A second aspect of this utility model provides a cup, the cup comprising 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.

[0017] The cup provided in this embodiment has the inner plug of any of the above embodiments, and thus has the technical effects of any of the above embodiments, which will not be described in detail here.

[0040] The following will combine Figures 1 to 5 The present invention describes an embodiment of the inner plug provided.

[0041] like Figures 1 to 3 As shown, a first aspect of this utility model provides an inner plug, which includes a lower cover assembly 20 and an upper cover assembly 10 detachably disposed within the lower cover assembly 20. A water outlet channel 230 is formed between the lower cover assembly 20 and the upper cover assembly 10. The upper cover assembly 10 includes: an upper cover body 110, which has an installation cavity 111 extending axially along the inner plug, and a stop portion 112 protruding toward the centerline of the inner plug on the side wall of the installation cavity 111; and a ratchet mechanism 120, which can be installed in the installation cavity 111 through the upper opening 1111 and is stopped and limited from below by the stop portion 112.

[0042] The inner plug in this embodiment makes the upper cover assembly 10 and the lower cover assembly 20 detachable, facilitating the removal of the upper cover assembly 10 for separate cleaning of both the upper cover assembly 10 and the lower cover assembly 20, and cleaning of the water outlet channel 230 between the upper cover assembly 10 and the lower cover assembly 20. This ensures drinking safety and prevents long-term liquid accumulation in the water outlet channel 230, which could lead to bacterial growth or unpleasant odors. Furthermore, a stop 112 is provided within the mounting cavity 111 of the upper cover body 110. After the upper cover assembly 10 and the lower cover assembly 20 are separated, the stop 112 blocks the ratchet body 122, preventing it from falling out of the mounting cavity 111 and solving the problem of the ratchet mechanism 120 falling out and being lost due to the removal of the upper cover assembly 10. In addition, the ratchet mechanism 120 is inserted into the mounting cavity 111 from above, making installation convenient.

[0043] Specifically, the ratchet mechanism 120 includes a ratchet seat 121, a ratchet body 122, and a ratchet push rod 123. Here, the ratchet seat 121 is installed inside the mounting cavity 111, and the ratchet seat 121 can be disassembled synchronously with the upper cover body 110, making it less likely to fall off. The ratchet body 122 and the ratchet push rod 123 are movably disposed in the hollow cavity of the ratchet seat 121 that extends axially along the inner plug. The ratchet body 122 can easily fall off and detach from the ratchet seat 121 and the upper cover body 110. Therefore, a stop part 112 is provided in the mounting cavity 111 to block the ratchet body 122, which can effectively prevent the ratchet body 122 from detaching from the upper cover body 110. At the same time, since the ratchet push rod 123 is located above the ratchet body 122, the stop part 112 can also indirectly prevent the ratchet push rod 123 from falling.

[0044] Figure 1 The diagram shown is a longitudinal cross-sectional view of the upper cover assembly 10 in normal operating condition, with the ratchet mechanism 120 located above the stop portion 112. Figure 2 and Figure 3 This diagram shows a cross-sectional view of the upper cover assembly 10 after it has been removed from the lower cover assembly 20. (Refer to...) Figure 2 and Figure 3 After the top cover assembly 10 is removed, the ratchet body 122 will lose the support of the valve assembly 220 and fall down under its own weight until it is stopped by the stop part 112, which can prevent the ratchet body 122 from detaching from the top cover body 110.

[0045] The ratchet seat 121 is an independent structure, subsequently mounted on the upper cover body 110. The ratchet seat 121 has corresponding ratchet teeth to engage with the ratchet teeth on the ratchet body 122. Compared to related technologies where the ratchet teeth are directly formed on the sidewall of the mounting cavity 111 of the upper cover body 110 to engage with the ratchet body 122, this simplifies the structure of the upper cover body 110 and facilitates its machining. Designing the finely detailed ratchet seat 121 independently ensures that even if it has significant errors and is scrapped, it will not affect the structure of the upper cover body 110, thus reducing manufacturing costs.

[0046] Furthermore, since the stop 112 blocks the falling ratchet body 122 from below, when installing the top cover assembly 10, the ratchet body 122 and ratchet push rod 123 can be first inserted into the mounting cavity 111 through the upper opening 1111, and then the ratchet seat 121 can be inserted into the mounting cavity 111 through the upper opening 1111 and fixed. In this way, the ratchet body 122 is limited between the stop 112 and the ratchet seat 121. During the installation process, the ratchet body 122 is not easy to fall off, making installation convenient.

[0047] Additionally, it is worth noting that the upper cover body 110 in this application has a mounting cavity 111 that extends axially along the inner plug. The inner diameter of the mounting cavity 111 may or may not be the same from top to bottom. For example... Figure 2 and Figure 3 As shown, the mounting cavity 111 necessarily has an upper opening 1111 and a lower opening 1112, thus referring to... Figure 1 This allows the button 130 to extend into the mounting cavity 111 through the upper opening 1111 and cooperate with the ratchet mechanism 120, and also allows the ratchet mechanism 120 to extend into the mounting cavity 111 through the lower opening 1112 and cooperate with the valve assembly 220.

[0048] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the stop portion 112 is distributed circumferentially along the side wall of the mounting cavity 111, and the inner diameter of the stop portion 112 is smaller than the maximum outer diameter of the ratchet body 122. Thus, regardless of the angle to which the ratchet body 122 rotates, when the upper cover assembly 10 is removed and the ratchet body 122 falls, the stop portion 112 can prevent the ratchet body 122 from falling further, effectively preventing the ratchet body 122 from being lost.

[0049] Furthermore, in some embodiments, the stop portion 112 is integrally formed with the upper cover body 110. This facilitates processing and ensures good connection stability, which in turn helps the ratchet body 122 to stably attach to the stop portion 112 after it is lowered. Moreover, it eliminates the need for assembly steps for the stop portion 112, improving assembly efficiency.

[0050] As an example, such as Figures 1 to 3 As shown, the cavity sidewall of the mounting cavity 111 has an integrally protruding inward stop rib, which forms a stop portion 112.

[0051] As an example, the lower part of the cavity sidewall of the mounting cavity 111 is recessed inward to form a stepped surface on the inside, and the stepped surface forms a stop portion 112.

[0052] Of course, in other examples, the stop 112 can also be a separate structure, which is subsequently installed in the mounting cavity 111.

[0053] Furthermore, in some embodiments, a guide structure is provided on the inner wall of the hollow cavity of the ratchet seat 121, and the ratchet push rod 123 can extend into the hollow cavity of the ratchet seat 121 to cooperate with the ratchet body 122 and move along the guide structure; wherein, when the ratchet body 122 is attached to the stop part 112, the ratchet push rod 123 maintains the guiding connection with the guide structure.

[0054] In these embodiments, by moving the ratchet push rod 123 along the guide structure, it is beneficial for the ratchet push rod 123 to accurately push the ratchet body 122 to rotate by a set angle, ensuring effective force transmission. After the upper cover assembly 10 and the lower cover assembly 20 are separated, the ratchet body 122 will slide onto the stop part 112. At this time, keeping the ratchet push rod 123 in a guiding connection with the guide structure can effectively prevent the ratchet push rod 123 from rotating during the sliding process. Thus, after the upper cover assembly 10 and the lower cover assembly 20 are reassembled, when the valve assembly 220 pushes the ratchet body 122 again, the ratchet body 122 can be correctly engaged with the ratchet push rod 123, avoiding the failure of the ratchet mechanism 120 transmission due to the reassembly of the upper cover assembly 10 and the lower cover assembly 20.

[0055] As an example, such as Figure 3 and Figure 5 As shown, in the outer peripheral surfaces of the guide structure and the ratchet push rod 123, one has a vertically extending guide groove 1211, and the other has a guide protrusion 1231 that mates with the guide groove 1211. The guide structure has a simple design and is easy to manufacture.

[0056] Furthermore, in some embodiments, such as Figure 1As shown, the lower cover assembly 20 includes an inner plug body 210 and a valve assembly 220. The inner plug body 210 is provided with an outlet 211 that communicates with the water outlet channel 230. The valve assembly 220 is disposed on the inner plug body 210 and can extend from the bottom into the mounting cavity 111 to abut against and cooperate with the ratchet body 122. The upper cover assembly 10 also includes a button 130, which is disposed on the top of the ratchet push rod 123. When the button 130 is pressed repeatedly, the ratchet push rod 123 can push the ratchet body 122 to rotate, thereby alternately pushing the valve assembly 220 to open and close the outlet 211.

[0057] In these embodiments, when a user needs to drink water, simply pressing button 130 will drive the ratchet mechanism 120 to push the valve assembly 220 to open the water outlet 211, allowing water to flow out through the water outlet 211 and the water outlet channel 230. This eliminates the need for the inner stopper to be fully open, making operation convenient. When drinking water is no longer needed, simply pressing button 130 again will rotate the ratchet body 122, causing the valve assembly 220 to reset and close the water outlet 211 under the elastic force of its own spring 224, improving the user experience.

[0058] Furthermore, such as Figure 1 As shown, the valve assembly 220 includes: a valve plate 221 disposed below the inner plug body 210 for blocking the outlet 211 from below; a valve stem 222 disposed in the middle of the upper surface of the valve plate 221, with circumferentially distributed abutment portions 223 on the upper part of the valve stem 222; and a spring 224 sleeved on the valve stem 222 and supported between the abutment portions 223 and the inner plug body 210 for applying a pulling force to the valve plate 221 to block the outlet 211 and applying a force to the valve stem 222 to abut against the ratchet body 122; wherein, the inner side of the stop portion 112 forms a clearance hole 113, the valve stem 222 passes through the clearance hole 113 and abuts against the ratchet body 122, and the outer diameter of the abutment portion 223 and the outer diameter of the spring 224 are both smaller than the diameter of the clearance hole 113. With this design, when the upper cover assembly 10 and the lower cover assembly 20 are separated, the valve assembly 220 can be dislodged from the clearance hole 113 without interfering with the stop part 112, which facilitates the separation of the upper cover assembly 10 and the lower cover assembly 20.

[0059] Furthermore, such as Figure 1 As shown, the valve assembly 220 also includes a valve plate water-blocking sealing ring 226. The valve plate water-blocking sealing ring 226 is disposed on the valve plate 221, and the valve plate water-blocking sealing ring 226 abuts against the inner plug body 210 to close the water outlet 211 and reduce the probability of water leakage.

[0060] Furthermore, such as Figure 1As shown, the valve assembly 220 also includes a valve stem water-blocking sealing ring 225, which is sleeved on the valve stem 222. The inner plug body 210 has an installation port, through which the valve stem 222 extends into the installation cavity 111 of the upper cover body 110, causing the outer periphery of the valve stem water-blocking sealing ring 225 to abut against the inner wall of the installation port, preventing water from entering the inner plug through the gap between the valve stem 222 and the inner plug body 210.

[0061] In a specific embodiment, such as Figures 1 to 5 As shown, the bottom of the button 130 has an annular rib, and the ratchet push rod 123 is sleeve-shaped, fitted around the outer periphery of the annular rib, and connected to the annular rib via a second snap-fit ​​1232. The lower end of the ratchet push rod 123 has a plurality of circumferentially distributed third ratchet teeth 1233. The ratchet body 122 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 123, and the upper surface of the ratchet disc is provided with a plurality of circumferentially distributed second ratchet teeth 1221. The ratchet seat 121 is sleeve-shaped, and the inner sidewall of the ratchet seat 121 is provided with a plurality of first ratchet teeth 1213 with their tips pointing downwards and circumferentially spaced. The first ratchet teeth 1213 can engage with the second ratchet teeth 1221, and a slot is formed between two circumferentially adjacent first ratchet teeth 1213.

[0062] When button 130 is pressed, it pushes ratchet push rod 123 downward. During this downward movement, the third ratchet tooth 1233 engages with the second ratchet tooth 1221, causing the ratchet body 122 to rotate at a set angle while moving downward, pushing the second ratchet tooth 1221 below the first ratchet tooth 1213. Then, when button 130 is released, the spring 224 of valve assembly 220 pushes the valve stem 222 upward, further pushing it upward. When the ratchet body 122 is raised, the second ratchet 1221 will move upward and insert into the first ratchet 1213. With the cooperation of the first ratchet 1213, it will rotate a second time at a set angle until it inserts into the root of the first ratchet 1213 and abuts against the first ratchet 1213. At this time, the first ratchet 1213 on the ratchet seat 121 can press down the valve stem 222 and the valve plate 221 through the ratchet body 122, so that the valve plate 221 moves down to open the water outlet 211, making it convenient for the user to drink water. When button 130 is pressed for the second time, button 130 pushes ratchet push rod 123 downward. During the downward movement of ratchet push rod 123, the third ratchet tooth 1233 will insert into the second ratchet tooth 1221 after the second rotation, pushing the ratchet body 122 to move downward while rotating a set angle for the third time, and separating the second ratchet tooth 1221 from the first ratchet tooth 1213. Then, when button 130 is released, spring 224 will push valve stem 222 upward, and then push ratchet body 122 upward, the third... After the second rotation, the second ratchet tooth 1221 on the ratchet body 122 will insert into the slot between two circumferentially adjacent first ratchet teeth 1213. The ratchet body 122 will then retract into the ratchet seat 121 until the second ratchet tooth 1221 abuts against the slot sidewall at the top of the slot, or the upper limit structure of the ratchet seat 121 restricts the ratchet body 122 or ratchet push rod 123 from moving upward. At this time, the spring 224 can push the valve rod 222 upward and simultaneously pull the valve plate 221 upward to close the outlet 211. Here, the slot can be constructed as a guide groove 1211 to limit the ratchet push rod 123. Of course, a guide groove 1211 different from the slot can also be additionally provided on the ratchet seat 121.

[0063] The ratchet mechanism 120 and the valve assembly 220 generally adopt the above-described cooperation method. The ratchet mechanism 120 and the valve assembly 220 can adopt the existing structure and cooperation principle, which will not be described in detail here.

[0064] Furthermore, in some embodiments, such as Figures 1 to 3 , Figure 5As shown, the ratchet seat 121 is sleeve-shaped, and its outer periphery is connected to the side wall of the mounting cavity 111 via a first snap fastener 1212; and / or the bottom of the ratchet seat 121 rests on the stop portion 112. This design allows the ratchet seat 121 to be stably installed within the mounting cavity 111, preventing it from shifting vertically, thus facilitating accurate engagement with the ratchet body 122. Especially when the bottom of the ratchet seat 121 rests on the stop portion 112, during installation, the ratchet seat 121 can be directly inserted into the mounting cavity 111 through the upper opening 1111 and received by the stop portion 112, making installation convenient and quick.

[0065] Of course, the ratchet seat 121 can also be installed in the mounting cavity 111 in other ways, such as by interference fit of the ratchet seat 121 into the mounting cavity 111, or by adhesive connection to the mounting cavity 111.

[0066] Regarding the detachable connection between the upper cover assembly 10 and the lower cover assembly 20, further, in some embodiments, such as Figures 1 to 3 As shown, a first connecting thread 114 is provided below the stop portion 112 on the side wall of the mounting cavity 111; the lower cover assembly 20 includes an inner plug body 210, on which an upwardly protruding connecting rib 212 is provided, and a second connecting thread 213 adapted to the first connecting thread 114 is provided on the connecting rib 212. In this way, the upper cover body 110 and the inner plug body 210 are threadedly connected, which facilitates the disassembly of the two, and the threaded connection has a good waterproof effect, which can prevent water from leaking out through the connection gap between the upper cover body 110 and the inner plug body 210.

[0067] Of course, in other embodiments, the upper cover assembly 10 and the lower cover assembly 20 may also be detachably connected in other ways, such as snap-fit ​​connection or rotational fastening connection.

[0068] Furthermore, in some embodiments, the lower cover assembly 20 also includes an inner plug sealing ring, which is sleeved on the outer periphery of the inner plug body 210 for fitting against the inner wall of the cup. This prevents water from flowing out through the gap between the inner plug body 210 and the cup when the inner plug is closed on the cup.

[0069] Furthermore, in some embodiments, the inner plug also includes a filter screen, which is detachably disposed at the bottom of the inner plug body 210. This facilitates the brewing of tea leaves and other ingredients within the container, enabling the cup to function as a brewing vessel.

[0070] A second aspect of this utility model provides a cup, the cup comprising 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.

[0071] The cup provided in this embodiment has the inner plug of any of the above embodiments, and thus has the technical effects of any of the above embodiments, which will not be described in detail here.

[0072] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
