Description

Technical Field

[0001] The utility model relates to the field of water containers, in particular to a cup cover and a cup. Background Art

[0002] To facilitate drinking water, a button is usually provided on the upper cover of the cup lid, and a ratchet mechanism is provided below the button. By pressing the button, the ratchet body of the ratchet mechanism rotates to open and close the water outlet of the cup lid. However, when the upper cover is removed for cleaning, the ratchet mechanism can easily fall off and be lost. Utility Model Content

[0003] Therefore, the purpose of the present invention is to provide a cup cover and a cup, so as to at least solve the problem that the ratchet mechanism is easy to fall off and lose.

[0004] The first aspect of the present invention provides a cup cover, which includes: an upper cover assembly, which includes an upper cover and a ratchet mechanism, and the upper cover is provided with a ratchet mechanism mounting cavity with a lower opening, and the ratchet mechanism is movably arranged in the ratchet mechanism mounting cavity; a stopper is arranged at the lower opening of the ratchet mechanism mounting cavity and is overlapped by the ratchet mechanism.

[0005] The cup cover of the embodiment of this aspect includes an upper cover assembly and a stopper. The stopper is arranged at the lower opening of the ratchet mechanism installation cavity to prevent the ratchet mechanism from falling from the ratchet mechanism installation cavity, thereby preventing the ratchet mechanism from being lost and facilitating the removal of the upper cover assembly for cleaning without having to worry about the ratchet mechanism being lost.

[0006] In some embodiments, the cup cover also includes: an inner plug assembly, which is detachably connected to the upper cover assembly and forms a water outlet channel between the inner plug assembly and the upper cover assembly, the inner plug assembly includes an inner plug, and the inner plug is provided with a water outlet connected to the water outlet channel; a valve assembly, which is arranged on the inner plug assembly, and the valve assembly can extend into the ratchet mechanism installation cavity and cooperate with the ratchet mechanism to open and close the water outlet.

[0007] In these embodiments, the cup lid includes an upper cover assembly, an inner plug assembly, and a valve assembly disposed on the inner plug assembly. The upper cover assembly and the inner plug assembly are detachably connected, facilitating separate cleaning of the upper cover assembly and the inner plug assembly, as well as cleaning the water outlet passage between the upper cover assembly and the inner plug assembly. This ensures drinking safety and prevents the long-term accumulation of liquid in the water outlet passage from breeding bacteria and producing odors. A valve assembly is disposed on the inner plug assembly, extending into the lower opening of the ratchet mechanism mounting cavity and cooperating with the ratchet mechanism to open and close the water outlet on the inner plug. Drinking water does not require fully opening the cup lid; simply operate the ratchet mechanism, resulting in convenient drinking and a good user experience.

[0008] In some embodiments, the stopper has a vertically extending escape hole in the middle, through which the valve assembly passes to engage with the ratchet mechanism. The escape hole prevents interference between the valve assembly and the stopper, ensuring that the ratchet mechanism can control the valve assembly to open and close the water outlet, ensuring accurate control of the water outlet opening. Furthermore, the stopper can still utilize the structure surrounding the escape hole to limit the ratchet mechanism, preventing it from disengaging from the lower opening of the ratchet mechanism mounting cavity.

[0009] In some embodiments, a stopper is disposed on the inner side of the lower opening of the ratchet mechanism installation cavity to prevent the ratchet mechanism from sliding off.

[0010] In these embodiments, the stopper is located below the ratchet mechanism within the ratchet mechanism mounting cavity, on the path the ratchet mechanism must take to escape from the ratchet mechanism mounting cavity. This facilitates the stopper to prevent the ratchet mechanism from escaping the ratchet mechanism mounting cavity. Furthermore, the stopper is located within the ratchet mechanism mounting cavity, resulting in a compact structure and minimal space occupation, without impacting the external structure of the upper cover.

[0011] In some embodiments, one of the outer wall of the stopper and the inner wall of the ratchet mechanism mounting cavity is provided with a rib, and the other is provided with a slot that matches the rib. The stopper is snap-connected to the ratchet mechanism mounting cavity via the rib and slot. This connection structure is simple and easy to manufacture. Furthermore, the stopper is easy to assemble and has good installation stability, preventing the stopper from disengaging from the ratchet mechanism mounting cavity, thereby ensuring that the stopper achieves its stopping effect.

[0012] In some embodiments, the bottom of the stopper extends out of the lower opening of the ratchet mechanism installation cavity and bends outward to form a flange, and the flange is used to abut against the inner plug assembly of the cup cover.

[0013] In these embodiments, during the installation of the stop member, the stop member can be inserted into the ratchet mechanism mounting cavity from the lower opening until the flange abuts against the lower edge of the lower opening. The flange can not only remind the user that the stop member is installed in place, but also limit the movement of the stop member into the ratchet mechanism mounting cavity, thereby preventing the stop member from affecting the movement of the ratchet mechanism due to being inserted too deeply into the ratchet mechanism mounting cavity.

[0014] In some embodiments, the stopper is an elastic seal. The stopper's elasticity allows it to better conform to the inner wall of the ratchet mechanism mounting cavity, improving its installation stability. Furthermore, when the stopper has the aforementioned flange, after the upper cover assembly and the inner plug assembly are connected, the flange is sandwiched between the upper cover and the inner plug, further providing a waterproofing effect, preventing water in the water outlet channel from entering the ratchet mechanism mounting cavity.

[0015] In some embodiments, the stopper is a plastic member that snaps onto the inner wall of the ratchet mechanism mounting cavity. The stopper is easy to manufacture and inexpensive. Furthermore, the snap connection between the stopper and the inner wall of the ratchet mechanism mounting cavity facilitates assembly.

[0016] In some embodiments, a guide structure is provided on the inner wall of the ratchet mechanism installation cavity, and the ratchet mechanism can move along the guide structure; when the stopper limits the ratchet mechanism, the ratchet mechanism maintains a guiding connection with the guide structure.

[0017] When the upper cover assembly is removed from the inner plug assembly, the ratchet mechanism can easily fall out of the lower opening of the ratchet mechanism mounting cavity and be lost. Even if it is not lost, the ratchet mechanism can easily rotate and shift during the sliding process, resulting in the ratchet mechanism not being able to function properly after the upper cover assembly is reassembled with the inner plug assembly. Therefore, in this embodiment, when the stopper limits the ratchet mechanism, the ratchet mechanism maintains a guiding connection with the guide structure. Therefore, the ratchet mechanism always maintains a guiding connection with the guide structure during the sliding process, which can prevent the ratchet mechanism from accidentally shifting and causing the ratchet mechanism transmission failure.

[0018] In some embodiments, the guide structure is a vertically extending guide groove, the ratchet mechanism includes a ratchet body and a ratchet link located above the ratchet body, the outer periphery of the ratchet link is provided with a guide protrusion that cooperates with the guide groove, the ratchet link can move up and down along the guide groove and push the ratchet body to rotate a set angle; when the ratchet body falls onto the stop member, the ratchet link falls and the guide protrusion is located in the guide groove.

[0019] In these embodiments, when the ratchet link is pressed, the ratchet link extends vertically downward along the guide groove and does not rotate or shift, thereby ensuring that the ratchet link accurately pushes the ratchet body to rotate the set angle, thereby ensuring effective force transmission. When the upper cover assembly and the inner plug assembly are separated, the ratchet link and the ratchet body will both slide down. During this process, the ratchet link will slide down along the guide groove. After the ratchet body slides onto the stopper, the guide protrusion on the ratchet link remains in the guide groove, effectively preventing the ratchet link from rotating during the sliding process. Therefore, after the upper cover assembly and the inner plug assembly are reassembled, when the valve assembly re-lifts the ratchet body, the ratchet body will still be properly engaged with the ratchet link, thereby avoiding transmission failure of the ratchet mechanism.

[0020] In some embodiments, the lower surface of the upper cover has a first annular rib protruding downward, and the first annular rib forms a ratchet mechanism installation cavity; the inner plug assembly includes an inner plug, and the bottom wall of the inner plug has a second annular rib protruding upward, and the first annular rib extends into the second annular rib and is threadedly connected to the second annular rib.

[0021] In these embodiments, the upper cover assembly and the inner plug assembly are threadedly connected, which facilitates disassembly on the one hand and is firmly connected on the other hand. In addition, the threaded connection method can reduce the probability of water in the water outlet channel entering the ratchet mechanism installation cavity, and has a good water blocking effect.

[0022] In some embodiments, the upper cover assembly further includes: a top cover, which is engaged with the top of the upper cover and has an opening; a button, which is limited between the top cover and the upper cover and exposed through the opening, and which is in contact with a ratchet mechanism. When the button is pressed multiple times, the ratchet mechanism can alternately push the valve assembly to open and close the water outlet. The water outlet can be opened and closed by operating the button, which is convenient to operate.

[0023] In some embodiments, the upper cover assembly further includes: a temperature measuring rod, which is arranged at the bottom of the button, the temperature measuring rod passes through the ratchet mechanism mounting cavity and extends from the bottom of the inner plug, and the temperature measuring rod also passes through the ratchet mechanism and the valve assembly.

[0024] In these embodiments, a temperature-sensing rod is positioned at the bottom of the button and extends from the bottom of the inner plug. When the cup lid is closed on the cup body, the temperature-sensing rod can extend into the cup body, contact the liquid, and measure the temperature of the liquid, thereby realizing the temperature measurement function of the cup lid. Furthermore, the temperature-sensing rod is connected to the bottom of the button and extends through the ratchet mechanism and valve assembly. The movement of the ratchet mechanism and valve assembly does not interfere with the temperature-sensing rod.

[0025] A second embodiment of the present invention provides a cup, comprising a cup body and a cup cover as described in any one of the above embodiments, wherein the cup cover is covered on the cup body.

[0050] The following will be combined Figures 1 to 8 The cup cover provided in the embodiment of the present utility model is introduced.

[0051] like Figure 1 、 Figure 3 and Figure 4 As shown, the first embodiment of the present invention provides a cup cover, which includes: an upper cover assembly 10, the upper cover assembly 10 includes an upper cover 110 and a ratchet mechanism 120, the upper cover 110 is provided with a ratchet mechanism mounting cavity 111 with a lower opening, and the ratchet mechanism 120 is movably arranged in the ratchet mechanism mounting cavity 111; a stopper 130 is arranged at the lower opening of the ratchet mechanism mounting cavity 111 and is overlapped by the ratchet mechanism 120.

[0052] The cup cover of this embodiment includes an upper cover assembly 10 and a stopper 130. The stopper 130 is disposed at the lower opening of the ratchet mechanism mounting cavity 111 to prevent the ratchet mechanism 120 from falling out of the ratchet mechanism mounting cavity 111, thereby preventing the ratchet mechanism 120 from being lost. This allows for easy removal of the upper cover assembly 10 for cleaning without worrying about the ratchet mechanism 120 being lost. Furthermore, when assembling the cup cover and assembling the upper cover assembly 10 with the other components of the cup cover, the stopper 130 also prevents the ratchet mechanism 120 from falling out of the ratchet mechanism mounting cavity 111, thereby facilitating assembly.

[0053] Figure 3The diagram shows a longitudinal cross-sectional view of the upper cover assembly 10 in a normal working state, in which the ratchet mechanism 120 is located above the stopper 130 . Figure 4 The longitudinal cross-sectional view of the upper cover assembly 10 after being disassembled from the inner plug assembly 20 is shown. Figure 4 After the upper cover assembly 10 is removed, the ratchet mechanism 120 will lose the support of the valve assembly 30 and fall downward under the influence of its own gravity until it is stopped by the stopper 130, which can prevent the ratchet mechanism 120 from escaping from the ratchet mechanism installation cavity 111.

[0054] It should be noted that the stopper 130 is disposed at the lower opening of the ratchet mechanism mounting cavity 111, but this does not necessarily mean that the stopper 130 is located at the lower edge of the lower opening. The stopper 130 can be located inside the lower opening and spaced a certain distance from the lower edge of the lower opening, or it can be located outside the lower opening and extend toward the lower edge of the lower opening. Any of these options is acceptable as long as the stopper 130 can prevent the ratchet mechanism 120 from escaping the ratchet mechanism mounting cavity 111 through the lower opening.

[0055] Furthermore, in some embodiments, Figure 1 and Figure 2 As shown, the cup lid also includes an inner plug assembly 20 and a valve assembly 30. The inner plug assembly 20 is detachably connected to the upper cover assembly 10, and a water outlet channel is formed between the inner plug assembly 20 and the upper cover assembly 10. The inner plug assembly 20 includes an inner plug 210, which is provided with a water outlet connected to the water outlet channel. The valve assembly 30 is disposed on the inner plug assembly 20 and can extend into the ratchet mechanism mounting cavity 111 to cooperate with the ratchet mechanism 120 to open and close the water outlet.

[0056] In these embodiments, the cup lid includes an upper cover assembly 10, an inner plug assembly 20, and a valve assembly 30 disposed on the inner plug assembly 20. The upper cover assembly 10 and the inner plug assembly 20 are detachably connected, making it convenient to clean the upper cover assembly 10 and the inner plug assembly 20 separately, and to clean the water outlet passage between the upper cover assembly 10 and the inner plug assembly 20, thereby ensuring drinking safety and preventing liquid from being deposited in the water outlet passage for a long time, breeding bacteria, or generating odor. The valve assembly 30 is disposed on the inner plug assembly 20. The valve assembly 30 extends into the lower opening of the ratchet mechanism mounting cavity 111 and cooperates with the ratchet mechanism 120 to open and close the water outlet on the inner plug 210. When drinking water, there is no need to fully open the cup lid; only the ratchet mechanism 120 needs to be operated, making drinking convenient and providing a good user experience.

[0057] Regarding the specific matching mode of the ratchet mechanism 120 and the valve assembly 30, further, as an example, Figure 1 、 Figures 5 to 7As shown, the ratchet mechanism 120 includes a ratchet link 121 and a ratchet body 122 located below the ratchet link 121. The ratchet body 122 is provided with circumferentially spaced first ratchet teeth, which are wedge-shaped. Second ratchet teeth that mate with the first ratchet teeth are spaced apart on the inner wall of the ratchet mechanism mounting cavity 111, with a gap between adjacent second ratchet teeth. The bottom of the ratchet link 121 has angular teeth that mate with the first ratchet teeth.

[0058] like Figure 1 and Figure 8 As shown, the valve assembly 30 includes a valve stem 310, a valve cap 320 located at the top end of the valve stem 310, a valve plate 330 located at the bottom end of the valve stem 310, and an elastic member 340. The elastic member 340 is sleeved on the valve stem 310, the top end of the elastic member 340 abuts against the valve cap 320, and the bottom end of the elastic member 340 abuts against the inner plug 210, so that under the elastic force of the elastic member 340, the valve stem 310 applies an upward force to the ratchet mechanism 120.

[0059] When the ratchet link 121 is pressed once, the ratchet link 121 applies a thrust to the ratchet body 122, and the angular teeth will push the ratchet body 122 to rotate to a set angle during the insertion of the first ratchet tooth. After releasing the pressure on the ratchet link 121, since the valve assembly 30 can apply an upward thrust to the ratchet body 122, the valve assembly 30 can push the first ratchet tooth of the rotated ratchet body 122 to engage with the second ratchet tooth, so that the valve plate 330 of the valve assembly 30 can be lifted up by the ratchet body 122 to open the water outlet on the inner plug 210. When the ratchet link 121 is pressed for the second time, the ratchet link 121 applies thrust to the ratchet body 122 again, and the angular teeth will push the ratchet body 122 to rotate the set angle again during the insertion of another first ratchet tooth. After releasing the pressure on the ratchet link 121, the valve assembly 30 can push the first ratchet tooth of the rotated ratchet body 122 into the gap. At this time, the valve plate 330 of the valve assembly 30 will not be lifted up by the ratchet body 122. Under the action of the elastic member 340 pushing the valve stem 310 upward, the valve plate 330 closes the water outlet on the inner plug 210.

[0060] The ratchet mechanism 120 and the valve assembly 30 generally adopt the above-mentioned matching manner. The ratchet mechanism 120 and the valve assembly 30 can adopt the structure and matching principle in the existing technology, which will not be described in detail here.

[0061] Furthermore, in some embodiments, Figure 1 、 Figure 3 and Figure 4As shown, the middle portion of the stopper 130 has a vertically extending escape hole 131, through which the valve assembly 30 passes to abut against the ratchet mechanism 120. The design of the escape hole 131 prevents interference between the valve assembly 30 and the stopper 130 during movement, ensuring that the ratchet mechanism 120 can control the valve assembly 30 to open and close the water outlet, ensuring accurate control of the water outlet opening. Furthermore, the stopper 130 can still utilize the structure surrounding the escape hole 131 to limit the position of the ratchet mechanism 120, preventing the ratchet mechanism 120 from disengaging from the lower opening of the ratchet mechanism mounting cavity 111.

[0062] Regarding the setting position of the stopper 130, further, in some embodiments, as Figure 1 、 Figure 3 and Figure 4 As shown, the stopper 130 is arranged on the inner side of the lower opening of the ratchet mechanism installation cavity 111. When the upper cover assembly 10 is separated from the inner cover assembly, the ratchet mechanism 120 can slide and rest on the stopper 130.

[0063] In these embodiments, the stopper 130 is located below the ratchet mechanism 120 within the ratchet mechanism mounting cavity 111, on a path that the ratchet mechanism 120 must take to escape from the ratchet mechanism mounting cavity 111. This facilitates the stopper 130 in preventing the ratchet mechanism 120 from escaping the ratchet mechanism mounting cavity 111. Furthermore, the stopper 130 is located within the ratchet mechanism mounting cavity 111, resulting in a compact structure and minimal space occupation, without affecting the external structure of the upper cover 110.

[0064] As an example, Figure 1 、 Figure 3 and Figure 4 As shown, the stopper 130 is cylindrical and circumferentially distributed along the inner wall of the ratchet mechanism mounting cavity 111. The stopper 130 has a simple structure and is easy to manufacture. Furthermore, when the ratchet mechanism 120 falls, the stopper 130 circumferentially prevents the ratchet mechanism 120 from falling. Regardless of the angle to which the ratchet body 122 of the ratchet mechanism 120 rotates, the ratchet body 122 can fall and rest on the stopper 130, providing a good stopping effect.

[0065] Of course, the stopper 130 may also be a non-cylindrical structure, such as a block, etc., and is not limited to the above examples.

[0066] Further, if Figure 1 、 Figure 3 and Figure 4As shown, one of the outer wall of the stopper 130 and the inner wall of the ratchet mechanism mounting cavity 111 is provided with a rib 132, and the other is provided with a slot 112 that matches the rib 132. The stopper 130 is connected to the ratchet mechanism mounting cavity 111 by means of the rib 132 and the slot 112. On the one hand, the connection structure is simple and easy to manufacture. On the other hand, the stopper 130 is easy to assemble and has good installation stability, which can prevent the stopper 130 from being separated from the ratchet mechanism mounting cavity 111, thereby ensuring that the stopper 130 can achieve its stopping effect.

[0067] In a specific application, the outer wall of the stopper 130 can be provided with multiple circles of ribs 132, and the inner wall of the ratchet mechanism mounting cavity 111 can be provided with corresponding circles of grooves 112. The stopper 130 and the ratchet mechanism mounting cavity 111 can be connected together at multiple locations, thereby improving the connection stability. Of course, it is also possible to have only one circle of ribs 132 on the outer wall of the stopper 130 and one circle of grooves 112 on the inner wall of the ratchet mechanism mounting cavity 111, which can simplify the structure and facilitate processing.

[0068] Of course, the stopper 130 can also be installed in the ratchet mechanism mounting cavity 111 in other ways. For example, the stopper 130 can also be pasted in the ratchet mechanism mounting cavity 111, or tightly fit with the inner wall of the ratchet mechanism mounting cavity 111, similar to an interference fit, or the stopper 130 can be welded in the ratchet mechanism mounting cavity 111, etc., which are not listed here one by one.

[0069] Further, if Figure 1 、 Figure 3 and Figure 4 As shown, the bottom of the stopper 130 extends out of the lower opening of the ratchet mechanism installation cavity 111 and bends outward to form a flange 133, which is also used to abut against the inner plug assembly 20 of the cup cover.

[0070] During the installation of the stopper 130, the stopper 130 can be inserted into the ratchet mechanism mounting cavity 111 from the lower opening until the flange 133 abuts against the lower edge of the lower opening. The flange 133 can not only remind the user that the stopper 130 is installed in place, which is conducive to the quick installation of the stopper 130, but also limit the stopper 130 from moving into the ratchet mechanism mounting cavity 111, thereby preventing the stopper 130 from affecting the movement of the ratchet mechanism 120 due to being inserted too deeply into the ratchet mechanism mounting cavity 111.

[0071] Further, if Figure 1 、 Figure 3 and Figure 4As shown, the stopper 130 is an elastic seal. The stopper 130 has a certain degree of elasticity, which allows it to better fit the inner wall of the ratchet mechanism mounting cavity 111 and reduce the chance of it falling. Furthermore, when the stopper 130 has the aforementioned flange 133, after the upper cover assembly 10 and the inner plug assembly 20 are connected, the flange 133 can be sandwiched between the upper cover 110 and the inner plug 210, further providing a waterproofing effect, preventing water in the water outlet channel from entering the ratchet mechanism mounting cavity 111.

[0072] As an example, the stopper 130 may be a rubber member or a silicone member, which has good elasticity, good sealing effect, and a certain supporting force, and can block the ratchet mechanism 120 from escaping from the ratchet mechanism mounting cavity 111 .

[0073] Of course, in other embodiments, the stopper 130 can also be a plastic member and snap-fitted to the inner wall of the ratchet mechanism mounting cavity 111. The stopper 130 is easy to manufacture and has low cost. Moreover, the snap-fitting connection between the stopper 130 and the inner wall of the ratchet mechanism mounting cavity 111 facilitates assembly.

[0074] Regarding the setting position of the stop member 130, further, in other embodiments, the stop member 130 is set at the bottom of the lower opening of the ratchet mechanism mounting cavity 111, and a part of the stop member 130 blocks a part of the lower opening of the ratchet mechanism mounting cavity 111; when the upper cover assembly 10 is separated from the inner cover assembly, the ratchet mechanism 120 can slide and be placed on the stop member 130.

[0075] In these embodiments, the stopper 130 is disposed outside the ratchet mechanism mounting cavity 111, thereby not occupying the internal space of the ratchet mechanism mounting cavity 111 and facilitating a reduction in the volume of the ratchet mechanism mounting cavity 111, thereby making the cup lid more compact. Furthermore, a portion of the stopper 130 blocks a portion of the lower opening of the ratchet mechanism mounting cavity 111. When the ratchet mechanism 120 is about to escape from the lower opening, it will slide onto the stopper 130 and be stopped by the stopper 130, thereby preventing the ratchet mechanism 120 from escaping the ratchet mechanism mounting cavity 111.

[0076] As an example, the stopper 130 is annular with a generally U-shaped cross-section, circumferentially surrounding the lower opening. The stopper 130 is securely mounted, and the portion extending into the interior of the lower opening prevents the ratchet mechanism 120 from disengaging from the ratchet mechanism mounting cavity 111. Furthermore, the stopper 130 occupies relatively little space within the interior of the lower opening, making it less likely to interfere with the valve assembly 30 and thereby affect the coordination between the valve assembly 30 and the ratchet mechanism 120.

[0077] Furthermore, in some embodiments, a guide structure is provided on the inner wall of the ratchet mechanism mounting cavity 111, and the ratchet mechanism 120 can move along the guide structure; when the stopper 130 limits the ratchet mechanism 120, the ratchet mechanism 120 maintains a guide connection with the guide structure.

[0078] When the upper cover assembly 10 is removed from the inner plug assembly 20, the ratchet mechanism 120 can easily fall out of the lower opening of the ratchet mechanism mounting cavity 111 and be lost. Even if it is not lost, the ratchet mechanism 120 can easily rotate and shift during the sliding process, resulting in the ratchet mechanism 120 being unable to function properly after the upper cover assembly 10 is reassembled with the inner plug assembly 20. Therefore, in this embodiment, when the stopper 130 limits the ratchet mechanism 120, the ratchet mechanism 120 maintains a guiding connection with the guide structure. Therefore, the ratchet mechanism 120 always maintains a guiding connection with the guide structure during the sliding process, thereby preventing the ratchet mechanism 120 from being accidentally shifted and causing the ratchet mechanism 120 to fail in transmission.

[0079] In some embodiments, as Figure 1 、 Figure 6 and Figure 7 As shown, the guide structure is a vertically extending guide groove 113, and the ratchet mechanism 120 includes a ratchet body 122 and a ratchet link 121 located above the ratchet body 122. The outer periphery of the ratchet link 121 is provided with a guide protrusion 1211 that cooperates with the guide groove 113. The ratchet link 121 can move up and down along the guide groove 113 and push the ratchet body 122 to rotate a set angle; when the ratchet body 122 falls onto the stopper 130, the ratchet link 121 falls and the guide protrusion 1211 is located in the guide groove 113.

[0080] In these embodiments, when the ratchet link 121 is pressed, the ratchet link 121 extends vertically downward along the guide slot 113 without rotating or shifting, thereby ensuring that the ratchet link 121 accurately pushes the ratchet body 122 to rotate a set angle, thereby ensuring effective transmission of force. When the upper cover assembly 10 is separated from the inner plug assembly 20, the ratchet link 121 and the ratchet body 122 will both slide down. During this process, the ratchet link 121 will slide along the guide groove 113, and after the ratchet body 122 slides onto the stopper 130, the guide protrusion 1211 on the ratchet link 121 is still located in the guide groove 113, which can effectively prevent the ratchet link 121 from rotating and dislocating during the sliding process. Therefore, after the upper cover assembly 10 and the inner plug assembly 20 are reassembled together, when the valve assembly 30 lifts up the ratchet body 122 again, the ratchet body 122 will still be correctly engaged with the ratchet link 121, avoiding the ratchet mechanism 120 from being unusable due to the ratchet body 122 falling off or the ratchet link 121 being dislocated, thereby ensuring that the ratchet mechanism 120 can be used normally.

[0081] Furthermore, in some embodiments, Figure 1 and Figure 2 As shown, the lower surface of the upper cover 110 has a first annular rib 114 protruding downward, and the first annular rib 114 surrounds the ratchet mechanism mounting cavity 111; the inner plug assembly 20 includes an inner plug 210, and the bottom wall of the inner plug 210 has a second annular rib 211 protruding upward, and the first annular rib 114 extends into the second annular rib 211 and is threadedly connected to the second annular rib 211.

[0082] In these embodiments, the upper cover assembly 10 and the inner plug assembly 20 are threadedly connected, which facilitates disassembly on the one hand and is firmly connected on the other hand. In addition, the threaded connection method can reduce the probability of water in the water outlet channel entering the ratchet mechanism installation cavity 111, and has a good water blocking effect.

[0083] In this case, the water outlet can be provided on the bottom wall of the inner plug 210 and located on the outer periphery of the second annular rib 211, which can reduce the probability of water entering the first annular rib 114 and the second annular rib 211. The number of the water outlet can be one or at least two.

[0084] In addition, if Figure 1 As shown, a mounting opening can be provided on the inner side of the second annular rib 211 on the bottom wall of the inner plug 210, and the valve stem 310 of the valve assembly 30 can be placed in the mounting opening, so that the valve plate 330 is located below the bottom wall of the inner plug 210, blocking the water outlet from below, and the valve cap 320 is located above the bottom wall of the inner plug 210. The elastic member 340 is supported between the bottom wall of the inner plug 210 and the valve cap 320. The elastic member 340 and the ratchet mechanism 120 are both located in the space enclosed by the first annular rib 114 and the second annular rib 211, and are not easily exposed to water. In addition, a valve stem water-blocking sealing ring 360 can be sleeved on the valve stem 310, and the outer periphery of the valve stem water-blocking sealing ring 360 can be abutted against the inner wall of the mounting opening to prevent water from entering the cup cover through the gap between the valve stem 310 and the inner plug 210.

[0085] In addition, if Figure 1 As shown, a valve plate water-blocking sealing ring 350 may be provided on the valve plate 330 , and the valve plate water-blocking sealing ring 350 is abutted against the inner plug 210 to close the water outlet and reduce the probability of water leakage.

[0086] Of course, the upper cover assembly 10 and the inner plug assembly 20 may also be detachably connected in other ways, such as a snap connection 115 or a rotational buckle connection. In this case, the inner plug 210 may not have the second annular rib 211, and the ratchet mechanism mounting cavity 111 may be formed only by the first annular rib 114 on the upper cover 110. When the upper cover assembly 10 and the inner plug assembly 20 are connected together, the bottom of the first annular rib 114 presses against the inner plug 210.

[0087] Furthermore, in some embodiments, Figure 1 、 Figure 3 and Figure 4 As shown, the upper cover assembly 10 further includes: a top cover 140, which is engaged with the top of the upper cover 110 and has an opening 141; a button 150, which is limited between the top cover 140 and the upper cover 110 and exposed through the opening 141. The button 150 also contacts the ratchet mechanism 120. When the button 150 is pressed multiple times, the ratchet mechanism 120 can alternately push the valve assembly 30 to open and close the water outlet. The water outlet can be opened and closed by operating the button 150, which is convenient to operate.

[0088] As an example, Figure 3 and Figure 4 As shown, the outer periphery of the top cover 140 has a downwardly extending flange, the inner side of the flange has a buckle slot 142, and the outer top side of the upper cover 110 has a buckle 115, which is locked in the buckle slot 142, thereby assembling the top cover 140 and the upper cover 110. The structure is simple and the assembly is convenient and quick. In addition, the flange of the top cover 140 covers the outer top side of the upper cover 110, which improves the appearance.

[0089] Of course, in other embodiments, the top cover 140 may also be fixed to the upper cover 110 in other ways, such as threaded connection, etc., and is not limited to the above examples.

[0090] Furthermore, in some embodiments, Figure 1 、 Figures 3 to 5 As shown, the upper cover assembly 10 also includes: a temperature measuring rod 160, which is arranged at the bottom of the button 150, and the temperature measuring rod 160 passes through the ratchet mechanism mounting cavity 111 and extends from the bottom of the inner plug 210, and the temperature measuring rod 160 also passes through the ratchet mechanism 120 and the valve assembly 30.

[0091] In these embodiments, a temperature measuring rod 160 is disposed at the bottom of the button 150 and extends from the bottom of the inner plug 210. When the cup lid is closed on the cup body, the temperature measuring rod 160 can extend into the cup body, contact the liquid, and measure the temperature of the liquid, thereby realizing the temperature measurement function of the cup lid. In addition, the temperature measuring rod 160 is connected to the bottom of the button 150 and passes through the ratchet mechanism 120 and the valve assembly 30. The movement of the ratchet mechanism 120 and the valve assembly 30 does not interfere with the temperature measuring rod 160.

[0092] To prevent water from entering the cup cover through the gap between the temperature measuring rod 160 and the valve assembly 30, further, as shown in FIG. Figure 1 As shown, a temperature measuring water-resistant sealing ring 370 can be provided on the temperature measuring rod 160 , and the temperature measuring water-resistant sealing ring 370 can be wrapped around the lower end of the valve stem 310 at the same time to prevent water from entering.

[0093] Furthermore, in some embodiments, Figure 1 As shown, the inner plug assembly 20 further includes an inner plug sealing ring 220, which is sleeved on the outer periphery of the inner plug 210 and is used to fit against the inner wall of the cup body. In this way, when the cup lid is closed on the cup body, water can be prevented from flowing out through the gap between the inner plug 210 and the cup body.

[0094] Furthermore, in some embodiments, Figure 1 As shown, the cup cover also includes a filter 40, which is detachably arranged at the bottom of the inner plug 210. It is convenient for tea and other ingredients in the container to achieve the brewing function of the cup.

[0095] A second embodiment of the present invention provides a cup, comprising a cup body and a cup cover as described in any one of the above embodiments, wherein the cup cover is covered on the cup body.

[0096] The cup provided in this embodiment has the cup cover 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.

[0097] Although the embodiments of the present invention have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that, in the opinion of those skilled in the art, such modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
