Description

Technical Field

[0001] This application relates to the technical field of daily necessities, and particularly to a container lid and a container. Background Art

[0002] A container generally includes a container body and a container lid. The container lid is usually connected to the mouth of the container body in a threaded manner to close the mouth of the container body. This connection method requires the user to hold the container body and the container lid with both hands and apply force to screw them together in order to install and remove the container lid, which is inconvenient to operate and affects the user experience. Summary of the Utility Model

[0003] This application provides a container lid and a container to simplify the opening operation of the container lid and improve the user experience of the container.

[0004] In a first aspect of this application, a container lid is provided, which includes:

[0005] A lid body;

[0006] An upper lid, at least a part of which is sleeved inside the lid body. A locking member is slidably arranged on the upper lid, and the locking member has a continuous use stroke and a disassembly stroke;

[0007] A switch member, movably connected to the lid body. The switch member has a closed position and an open position to adjust the movement stroke of the locking member;

[0008] When the switch member is in the closed position, the switch member limits the locking member to the use stroke. A part of the locking member penetrates through the lid body and can be exposed outside the outer periphery of the lid body;

[0009] When the switch member is in the open position, the switch member releases the limitation on the locking member, and the locking member can move from the use stroke to the disassembly stroke so that the locking member disengages from the lid body.

[0010] The container lid provided by the present application includes a lid body, an upper lid, and a switch member; at least a part of the upper lid is sleeved in the lid body, and a locking member is slidably provided on the upper lid. The locking member has a continuous use stroke and a disassembly stroke, and the disassembly stroke is located on the side of the use stroke closer to the axis of the lid body; the switch member is movably connected to the lid body, and the switch member has a closed position and an open position to adjust the movement stroke of the locking member. When the switch member is in the closed position, the switch member confines the locking member to the use stroke. A part of the locking member penetrates through the lid body and can be exposed on the outer periphery of the lid body. The movement of the locking member can only change the connection state between the locking member and the container body, thereby realizing the connection and fixation or disassembly and separation of the container lid and the container body. The operation of opening the lid is convenient, the use experience is improved, and it can prevent the upper lid from accidentally loosening or falling off during use; when the switch member is in the open position, the switch member releases the limitation on the locking member, and the locking member can move from the use stroke to the disassembly stroke, so that the locking member disengages from the lid body. The movement of the locking member can change the connection state between the locking member and the lid body, and separate and disassemble the upper lid and the lid body. This can not only facilitate the internal cleaning of the container lid, improve the cleanliness and hygiene of the container lid during use, but also facilitate the installation and replacement of various components inside the container lid, and simplify the assembly and later maintenance of the container lid.

[0011] Optionally, a slideway is provided on the upper lid corresponding to the locking member. The slideway extends along the radial direction of the upper lid, and the locking member is installed in the slideway. Through the circumferential direction of the slideway around the locking member, a circumferential stable support limit and an axial precise guidance can be provided for the locking member, making the action of the locking member more flexible and efficient. It can not only make the operation of the locking member more labor-saving, but also reduce the risk of jamming during the movement of the locking member, ensuring that the locking member can accurately achieve buckling and disengagement of the buckle.

[0012] Optionally, the upper lid includes a detachable bottom shell and a top cover. A groove is provided at the top of the bottom shell, and the top cover at least covers a part of the notch of the groove. The groove and the top cover jointly form the slideway. The bottom of the locking member is supported on the bottom of the groove, and both sides of the locking member are supported on the side walls of the groove, thereby forming a reliable support and precise guidance for the locking member; the top cover abuts against the top of the locking member to prevent the locking member from swinging or vibrating up and down, further increasing the stability of the action of the locking member.

[0013] Optionally, one end of the slideway away from the axis of the upper lid is the first end, and one end of the slideway close to the axis of the upper lid is the second end. The switch member is arranged at the second end of the slideway. The switch member can stop or avoid the locking member, and change the movement stroke of the locking member by the way of stopping at the end. The structure is simple and easy to implement, and it can keep the structural integrity of both the locking member and the switch member.

[0014] Optionally, the upper cover is provided with a support portion at the second end of the slideway. The switch member is arranged below the support portion, and a part of the switch member extends between the slideway and the support portion. The support portion is used to define the end point of the disassembly stroke close to the axis of the upper cover. When the switch member is in the open position and the locking member moves towards the direction close to the axis of the upper cover, the locking member can abut against the support portion to achieve limit, so that it cannot further move towards the direction close to the axis of the upper cover, preventing the locking member from sliding out or jamming at the second end of the slideway, etc., which affects the normal use of the container cover.

[0015] Optionally, the support portion forms a recessed area at the bottom of the upper cover, and the switch member is arranged in the recessed area, which can not only ensure that the switch member can face the locking member directly and play a reliable stopping role, but also improve the compactness of the overall structure of the container cover.

[0016] Optionally, a spacing groove is provided between the support portion and the slideway, and a protruding portion is provided at the edge of the switch member. The protruding portion extends upward and extends into the spacing groove, and the edge of the protruding portion fits with the edge of the support portion. On the one hand, the protruding portion limits the switch member to improve the stability of the switch member and prevent the switch member from shaking left and right during use, resulting in the loosening or falling off of the switch member; on the other hand, by providing the protruding portion, the effective area of the switch member facing the slideway is increased, ensuring that the switch member can form a reliable stop limit for the locking member.

[0017] Optionally, the upper cover includes two locking members, the two locking members are symmetrical to each other, and a first elastic member is arranged between the two locking members. The two ends of the first elastic member elastically abut against the two locking members respectively to force the locking members to move away from the axis of the upper cover. The user can operate the two locking members in a pinching manner with two fingers. At the same time, after the user pinches the two locking members, the user can also lift the container cover or the upper cover upward, further simplifying the opening operation and the disassembly and separation operation of the upper cover. Moreover, under the action of the first elastic member, the locking portion can stably stay in the state of protruding from the cover body, ensuring that the container cover and the container body will not be separated from each other during use.

[0018] Optionally, the cover body is provided with a water outlet channel, and the container cover further includes a valve assembly. The valve assembly is slidably connected to the cover body to open or close the water outlet channel, and the switch member drives the valve assembly to move. When an external force is applied to the switch member by the user, the valve assembly can be opened or closed according to needs, improving the convenience of the pouring operation. Thus, the switch member also has the function of controlling the water outlet at the same time, and integrating the switch for controlling the water outlet and the switch for limiting the locking member into one can reduce the number of parts and simplify the overall structure of the container cover.

[0019] The second aspect of the present application provides a container, which includes a container body and any one of the container lids provided by the present application;

[0020] A locking groove is provided at the mouth of the container body. The container lid is covered on the mouth of the container body, and the locking member can be inserted into or removed from the locking groove.

[0021] It should be understood that the above general description and the following detailed description are only exemplary and do not limit the present application. Description of the Drawings

[0063] The accompanying drawings here are incorporated into the specification and form a part of this specification, showing embodiments consistent with this application, and are used together with the specification to explain the principles of this application. Detailed implementation manners

[0064] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0065] In the description of the present application, unless otherwise clearly specified and limited, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance; unless otherwise specified or stated, the term "plurality" means two or more; the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0066] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of the present application are described from the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0067] As Figure 1 shown, the embodiments of the present application provide a container, which includes a container body 20 and a container lid 10. A locking member 21 is slidably provided on the container lid 10, and the locking member 21 can be locked to the container body 20 to fix the container lid 10 to the container body 20.

[0068] Specifically, a locking groove 20a is provided at the mouth of the container body 20. At least a part of the container lid 10 is embedded in the mouth of the container body 20, and the locking member 21 can be inserted into or removed from the locking groove 20a. When the locking member 21 is inserted into the locking groove 20a, the container lid 10 and the container body 20 are locked to the container body 20; when the locking member 21 is removed from the locking groove 20a, the container lid 10 and the container body 20 can be separated from each other.

[0069] As Figures 2 - 8As shown in the figure, the container lid 10 provided by the embodiment of the present application includes a lid body 1 and an upper lid 2. The lid body 1 has an inner cavity 11. The top of the inner cavity 11 has an opening, and through holes 12 are provided on the outer periphery of the lid body 1. The upper lid 2 is arranged at the opening of the lid body 1, and at least a part of the upper lid 2 is sleeved inside the lid body 1. A locking member 21 is slidably arranged on the upper lid 2. The locking member 21 can slide along the radial direction of the upper lid 2. The locking member 21 has a continuous use stroke and a disassembly stroke. The disassembly stroke is located on the side of the use stroke closer to the axis of the lid body 1. When the locking member 21 moves in the use stroke (refer to Figure 2 ), a part of the locking member 21 passes through the through hole 12 of the lid body 1 and is exposed outside the outer periphery of the lid body 1, so that it can be locked to the container body 20 (that is, the locking member 21 can be snapped into or out of the locking groove 201), and the overall installation and fixation or disassembly and separation of the container lid 10 can be realized; when the locking member 21 moves in the disassembly stroke (refer to Figure 3 and Figure 4 ), the locking member 21 can be separated from the lid body 1 (that is, the locking member 21 can be snapped into or out of the through hole 12), so that the upper lid 2 and the lid body 1 can be separated and disassembled from each other. This can not only facilitate the internal cleaning of the container lid 10, improve the cleanliness and hygiene of the use of the container lid 10, but also facilitate the installation and replacement of the internal components of the container lid 10, and simplify the assembly and later maintenance of the container lid 10. In addition, the locking member 21 locks the upper lid 2, the lid body 1 and the container body 20 at the same time, or the locking member 21 locks the upper lid 2 and the lid body 1 alone. The overall installation and fixation of the container lid 10 and the internal assembly connection of the container lid 10 are realized through the same locking member 21, reducing the number of components, simplifying the overall structure of the container lid 10, and improving the compactness of the structure of the container lid 10.

[0070] Furthermore, the container lid 10 further includes a switch member 3. The switch member 3 is movably connected to the lid body 1. For example, the switch member 3 can be slidably connected to the lid body 1 or pivotally connected to the lid body 1. The switch member 3 has a closed position and an open position to adjust the movement stroke of the locking member 21. By alternately blocking and releasing the free stroke of the locking member 21 by the switch member 3, both the use safety of the container lid 10 can be ensured and the disassembly convenience of the container lid 10 can be satisfied. The switch member 3 can be a push-button switch, a rotary switch, a toggle switch, etc., as long as it can adjust the movement stroke of the locking member 21.

[0071] When the switch member 3 is in the closed position (refer to Figure 3) The locking member 21 is limited to the use stroke by the switch member 3, so that the locking member 21 cannot move further inward and disengage from the through hole 12. The locking member 21 always remains in the state of passing through the through hole 12 of the cover body 1. That is to say, the movement of the locking member 21 can only change the connection state between the locking member 21 and the container body 20, so as to realize the connection and fixation or disassembly and separation of the container cover 10 and the container body 20. Therefore, when the switch member 3 is in the closed position, the user only needs to apply an external force to the locking member 21 to make the locking member 21 move radially along the upper cover 2, and the locking member 21 can be retracted to open the container cover 10. The opening operation is convenient, improving the user experience. Moreover, when the switch member 3 is in the closed position, the movement of the locking member 21 does not change the connection state between the locking member 21 and the cover body 1, so that the upper cover 2 and the cover body 1 maintain a reliable connection state, and the container cover 10 forms a complete whole, meeting the normal use requirements of the container cover 10 and preventing the upper cover 2 from accidentally loosening or falling off during use.

[0072] When the switch member 3 is in the open position (refer to Figure 4 and Figure 5 ), the switch member 3 releases the limitation on the locking member 21, and the locking member 21 can move from the use stroke to the disassembly stroke, and the locking member 21 can move further inward and disengage from the through hole 12 of the cover body 1. That is to say, the movement of the locking member 21 can change the connection state between the locking member 21 and the cover body 1. Therefore, when the switch member 3 is in the open position, the user only needs to apply an external force to the locking member 21 to make the locking member 21 move radially along the upper cover 2, and the upper cover 2 and the cover body 1 can be separated and disassembled from each other, which can not only facilitate the internal cleaning of the container cover 10, improve the cleanliness and hygiene of the use of the container cover 10, but also facilitate the installation and replacement of each component inside the container cover 10, simplifying the assembly and later maintenance of the container cover 10.

[0073] Specifically, a part of the locking member 21 is exposed at the top of the upper cover 2 to form an operation part 211, so as to facilitate the user to apply an external force to the locking member 21; another part of the locking member 21 can extend out of the outer periphery of the upper cover 2 to form a locking part 212 to realize the locking function of the locking member 21. At least a part of the container cover 10 is embedded in the mouth of the container body 20, so that a part of the container body 20 surrounds the outside of the container cover 10, facilitating the locking cooperation between the locking part 212 and the container body 20.

[0074] Among them, the number of the locking members 21 can be reasonably set according to needs. For example, the number of the locking members 21 is one, two or more than three. When the number of the locking members 21 is at least two, the locking members 21 are distributed at intervals around the axis of the upper cover 2.

[0075] Furthermore, the number of the locking members 21 is two, and the two locking members 21 are symmetric with each other. The user can operate the two locking members 21 in a pinching manner with two fingers. At the same time, after the user pinches the two locking members 21, the container cover 10 or the upper cover 2 can be lifted upward, further simplifying the opening operation of the cover and the disassembly and separation operation of the upper cover 2. Specifically, when the switch member 3 is in the closed position, after the user pinches the two locking members 21, the container cover 10 can be lifted upward to achieve the opening operation of the cover; when the switch member 3 is in the open position, the user pinches the two locking members 21, and the upper cover 2 can be lifted upward to achieve the disassembly and separation operation of the upper cover 2.

[0076] Furthermore, a first elastic member 27 is provided at one end of the locking member 21 close to the axis of the upper cover 2. The first elastic member 27 elastically abuts against the locking member 21 to force the locking member 21 to move outward (in the direction away from the axis of the upper cover 2). That is to say, in the natural state, the locking portion 212 can stably stay in the state of protruding from the cover body 1, ensuring that the container cover 10 and the container body 20 will not be separated from each other during use.

[0077] Furthermore, when the number of the locking members 21 is two, the first elastic member 27 is arranged between the two locking members 21, and both ends of the first elastic member 27 elastically abut against the two symmetrically arranged locking members 21 respectively, so that the two locking members 21 can be simultaneously subjected to equal and opposite elastic acting forces, improving the consistency of the actions of the two locking members 21. It can be understood that in other embodiments, a separate first elastic member 27 can be provided corresponding to each locking member 21.

[0078] Furthermore, the upper cover 2 is provided with sliding channels 22 corresponding to the locking members 21. That is to say, the sliding channels 22 are arranged in one-to-one correspondence with the locking members 21, and the sliding channels 22 extend along the radial direction of the upper cover 2, and the locking members 21 are installed in the sliding channels 22. Through the circumferential direction of the sliding channels 22 around the locking members 21, circumferential stable support and limit and axial precise guidance can be provided for the locking members 21, making the actions of the locking members 21 more flexible and efficient. It can not only make the operation of the locking members 21 more labor-saving, but also reduce the risk of jamming during the movement of the locking members 21, ensuring that the locking members 21 can accurately achieve buckling and disengagement of the buckle. It can be understood that in other embodiments, guiding structures such as sliding grooves can also be provided corresponding to the locking members 21.

[0079] Furthermore, one end of the sliding channel 22 away from the axis of the upper cover 2 is the first end, and a limiting portion is provided at the first end. The locking member 21 and the limiting portion are mutually stopped and limited to limit the outward movement stroke of the locking member 21 to prevent the locking member 21 from falling out of the upper cover 2. The limiting portion is formed with a through hole, and the locking portion 212 passes through the through hole and extends out of the outside of the upper cover 2, so that the locking portion 212 can realize the normal locking function.

[0080] Further, one end of the slideway 22 close to the axis of the upper cover 2 is the second end, and the switch member 3 is arranged at the second end of the slideway 22. The switch member 3 can stop or avoid the locking member 21, and by stopping at the end, the movement stroke of the locking member 21 is changed. The structure is simple and easy to implement, and both the locking member 21 and the switch member 3 can maintain the integrity of their own structures. Specifically, when the switch member 3 is in the closed position, at least a part of the switch member 3 faces the slideway 22, so that the switch member 3 can stop the locking member 21, making the locking member 21 unable to move further inward; when the switch member 3 is in the open position, the switch member 3 avoids the slideway 22, so that the switch member 3 can avoid the slideway 22, making the locking member 21 able to move further inward.

[0081] Further, the upper cover 2 is provided with a support portion 24 at the second end of the slideway 22. The locking member 3 is arranged below the support portion 24, and a part of the switch member 3 extends between the slideway 22 and the support portion 24. That is to say, along the movement direction of the locking member 3, the edge of the switch member 3 is closer to the locking member 21 than the edge of the support portion 24. The switch member 3 is used to define the end point of the use stroke close to the axis of the upper cover 2, and the support portion 24 is used to define the end point of the disassembly stroke close to the axis of the upper cover 2. When the switch member 3 is in the closed position and the locking member 21 moves in the direction close to the axis of the upper cover 2, the locking member 21 abuts against the switch member 3 to achieve limit, so that it cannot move further in the direction close to the axis of the upper cover 2, preventing the upper cover 2 from loosening or falling off accidentally; when the switch member is in the open position and the locking member 21 moves in the direction close to the axis of the upper cover 2, the locking member 21 can abut against the support portion 24 to achieve limit, so that it cannot move further in the direction close to the axis of the upper cover 2, preventing the locking member 21 from sliding out or getting stuck at the second end of the slideway 22, etc., affecting the normal use of the container lid 10. In addition, the support portion 24 can be lap-fitted with the inside of the cover body 1, so as to provide a supporting effect on the whole upper cover 2, preventing the upper cover 2 from collapsing downward in the cover body 1.

[0082] Further, the switch member 3 can move in the direction close to or away from the support portion 24. That is to say, the switch member 3 moves in the vertical plane, so that the movement plane of the switch member 3 is perpendicular to the movement plane of the locking member 21, ensuring that the switch member 3 can provide a reliable stopping effect on the locking member 21. When the switch member 3 moves in the direction close to the support portion 24 and abuts against the lower part of the support portion 24, the switch member 3 is in the closed position. That is to say, under normal use conditions of the container lid 10, the upper cover 2 can be lapped above the switch member 3, and the switch member 3 provides a supporting effect on the upper cover 2. When the switch member 3 moves in the direction away from the support portion 24, the switch member 3 can move to the open position. It can be understood that in other embodiments, the switch member 3 can move along the extension direction of the support portion 24, so that the movement plane of the switch member 3 is parallel to the movement plane of the locking member 21.

[0083] Further, a guiding surface may be provided at the second end of the sliding track 22. The guiding surface extends upward from the bottom end of the sliding track 22. Along the direction from bottom to top, the guiding surface gradually inclines towards the direction close to the axis of the upper cover 2. When the upper cover 2 is inserted into the cover body 1, the guiding surface abuts against the edge of the switch member 3. Through the inclined guiding surface, the relative movement of the upper cover 2 and the switch member 3 along the axis is converted into the relative movement in the radial direction, thereby adjusting the positions of the upper cover 2 or the switch member 3 in the cover body 1 and preventing the upper cover 2 and the switch member 3 from interfering with each other, which may cause difficulty in the normal installation of the upper cover 2.

[0084] Further, the supporting portion 24 forms a recessed area 25 at the bottom of the upper cover 2, and the switch member 3 is disposed in the recessed area 25, which can not only ensure that the switch member 3 can be directly opposite to the sliding track 22 and play a reliable stopping role, but also improve the compactness of the overall structure of the container cover 10.

[0085] Further, a spacing groove 26 is provided between the supporting portion 24 and the sliding track 22. A protruding portion 31 is provided at the edge of the switch member 3. The protruding portion 31 extends upward and extends into the spacing groove 26, and the protruding portion 31 fits against the edge of the supporting portion 24. On the one hand, the protruding portion 31 limits the switch member 3, improves the stability of the switch member 3, and prevents the switch member 3 from shaking left and right during use, which may cause the switch member 3 to become loose or fall off. On the other hand, by providing the protruding portion 31, the effective area of the switch member 3 facing the sliding track 22 is increased, ensuring that the switch member 3 can form a reliable stopping limit for the locking member 21.

[0086] Further, when the number of the locking members 3 is two, the upper cover 2 is provided with two symmetrically arranged sliding tracks 22. The supporting portion 24 is disposed between the two sliding tracks 22, and a channel communicating the two sliding tracks 22 is formed above the supporting portion 24. The first elastic member 27 is installed in the channel, and the channel plays a role in supporting and limiting the first elastic member 27, preventing the first elastic member 27 from generating a large bending deformation and affecting the normal movement of the locking member 3.

[0087] Further, as Figure 6 and Figure 7 shown, the upper cover 2 includes a detachable bottom shell 2a and a top cover 2b. A groove 23 is provided at the top of the bottom shell 2a, and the top cover 2b at least covers a part of the notch of the groove 23. The groove 23 and the top cover 2b together form the sliding track 22. The bottom of the locking member 21 is supported on the bottom of the groove 23, and both sides of the locking member 21 are supported on the side walls of the groove 23, thereby forming a reliable support and precise guidance for the locking member 21. The top cover 2b abuts against the top of the locking member 21 to prevent the locking member 21 from swinging or vibrating up and down, further increasing the stability of the operation of the locking member 21.

[0088] Among them, the cross-section of the top cover 2b matches the cross-section of the cover body 1 to ensure that the upper cover 2 can completely close the opening of the cover body 1, improving the appearance of the container lid 10. The bottom shell 2a includes two first side portions and two second side portions. The two first side portions are oppositely arranged along the moving direction of the locking portion 212, and the second side portions are connected to the first side portions to form a closed frame structure; the first side portions are mutually attached to the inner surface of the cover body 1 to increase the stability of the connection of the locking member 21; the second side portions are mutually spaced from the inner surface of the cover body 1 to reduce the weight of the upper cover 2.

[0089] As Figures 2 - 5 , Figure 8 and Figure 9 shown, the cover body 1 is provided with a water outlet channel 13. The water outlet channel 13 runs through both ends of the cover body 1 and is used to discharge the liquid in the container body 20, so that the pouring function can be realized without opening the lid. Specifically, one end of the water outlet channel 13 is located at the bottom of the cover body 1 to form a water inlet communicating with the container body 20, so that the liquid in the container body 20 can flow into the water outlet channel 13; the other end of the water outlet channel 13 is located on the side wall of the cover body 1 to form a water outlet communicating with the outside, so that the liquid in the water outlet channel 13 can flow out to the outside. The water outlet channel 13 is separated from the inner cavity 11 of the cover body 1 to prevent the components installed in the inner cavity 11 from contacting the liquid, resulting in liquid pollution or component damage.

[0090] Furthermore, the container lid 10 further includes a valve assembly 4. The valve assembly 4 is slidably connected to the cover body 1 to open or close the water outlet channel 13, and the switch member 3 drives the valve assembly 4 to move. When the user applies an external force to the switch member 3, the valve assembly 4 can be opened or closed as needed to open or close the water outlet channel 13, improving the convenience of the pouring operation. Thus, the switch member 3 simultaneously has the function of controlling the water outlet. Integrating the control of the water outlet switch and the switch for limiting the locking member 21 into one can reduce the number of components and simplify the overall structure of the container lid 10. A part of the switch member 3 extends beyond the edge of the cover body 1 to form a handle 32 to facilitate the user to apply an external force to the switch member 3. It can be understood that in other embodiments, the switch for controlling the water outlet and the switch for limiting the locking member 21 can be separately provided.

[0091] Furthermore, the valve assembly 4 includes a valve rod 41 and a valve disc 42 that are connected to each other. The valve rod 41 is slidably connected to the cover body 1, and the valve disc 42 is arranged at one end of the water outlet channel 13 to open or close the water outlet channel 13. Specifically, the valve disc 42 can move together with the valve rod 41 in the direction close to the water outlet channel 13 to close the water outlet channel 13, or the valve disc 42 can move together with the valve rod 41 in the direction away from the water outlet channel 13 to open the water outlet channel 13.

[0092] Among them, the valve stem 41 and the valve disc 42 can be connected to each other in a fixed manner or in a movable manner, as long as the valve disc 42 can move together with the valve stem 41. When the valve stem 41 and the valve disc 42 are connected to each other in a fixed manner, the valve stem 41 and the valve disc 42 can be integrally connected by non-detachable means such as injection molding, or can be detachably connected to each other by means such as screw fitting or snap fitting.

[0093] Further, the valve stem 41 passes through the valve disc 42. One end of the valve stem 41 is provided with a stop portion 411. The stop portion 411 is an annular structure protruding from the radial direction of the valve stem 41. The stop portion 411 is located on the side of the valve disc 42 away from the water outlet passage 13, so that the valve disc 42 can move together with the valve stem 41 in the direction close to the water outlet passage 13 to close the water outlet passage 13. An axial supporting force is provided to the valve disc 42 through the stop portion 411, improving the reliability of the cooperation between the valve disc 42 and the water outlet passage 13.

[0094] Further, the valve assembly 4 further includes a second elastic member 43. The second elastic member 43 is installed in the inner cavity 11 of the cover body 1. The lower end of the second elastic member 43 is supported on the bottom of the cover body 1, and the upper end of the second elastic member 43 elastically abuts against the valve stem 41 to force the valve stem 41 to drive the valve disc 42 to move upward, so that the valve disc 42 can stably stay at the position of closing the water outlet passage 13, ensuring that the liquid in the container body 20 does not leak under the natural state.

[0095] Further, the valve disc 42 is slidably connected to the valve stem 41. That is to say, the valve stem 41 and the valve disc 42 are connected to each other in a movable manner. The valve stem 41 can move independently of the valve disc 42. It can not only play the role of pre-exhausting air, preventing high-temperature gas from spraying out and scalding the user, but also make the operation of opening the water outlet passage 13 more convenient and labor-saving. Specifically, the stop portion 411 can elastically abut against the side of the valve disc 42 away from the water outlet passage 13, so that a sealed state is formed between the stop portion 411 and the valve disc 42, preventing the liquid in the container body 20 from leaking; when it is necessary to open the water outlet passage 13, the user applies an external force to the valve stem 41 (for example, presses down the switch member 3), so that the stop portion 411 moves in the direction away from the valve disc 42, and the stop portion 411 and the valve disc 42 are separated from each other, thus destroying the sealed state between the valve stem 41 and the valve disc 42, enabling the high-temperature gas inside the container body 20 to be discharged, avoiding the high-temperature gas in the container body 20 from spraying out and scalding the user during the operation of opening the cover. Moreover, since the cross-sectional area of the stop portion 411 is much smaller than the cross-sectional area of the valve disc 42, the gas pressure received by the valve stem 41 is much smaller than that of the valve disc 42, making the operation of opening the water outlet passage 13 more convenient and labor-saving.

[0096] Further, a seal 412 is sleeved on the stopper portion 411. The seal 412 elastically abuts against the side of the valve disc 42 away from the water outlet passage 13 as the stopper portion 411 moves, so as to ensure a reliable end face sealing fit between the valve stem 41 and the valve disc 42, and prevent the liquid in the container body 20 from leaking along the gap between the valve stem 41 and the valve disc 42.

[0097] Further, a plurality of ridges 413 are provided on the outer periphery of the valve stem 41. The ridges 413 extend along the axial direction of the valve stem 41, and the ridges 413 are arranged at intervals around the axis of the valve stem 41. An exhaust groove 414 is formed between adjacent ridges 413. On the one hand, by providing the exhaust groove 414, the circumferential contact area between the valve stem 41 and the valve disc 42 is reduced, thereby reducing the resistance of the relative movement between the valve stem 41 and the valve disc 42, and making the operation of opening the water outlet passage 13 more convenient and labor-saving. On the other hand, after the stopper portion 411 and the valve disc 42 are separated from each other, the upper and lower sides of the valve disc 42 are communicated with each other through the exhaust groove 414, so that the high-temperature gas in the container body 20 can be quickly discharged, reducing the air pressure in the container body 20, avoiding the generation of a pressure difference between the upper and lower sides of the valve disc 42, and ensuring that the valve disc 42 can be opened normally. It can be understood that other exhaust structures can also be provided between the valve stem 41 and the valve disc 42. For example, an exhaust through hole 12 can be provided at the position of the valve disc 42 facing the stopper portion 411, as long as the upper and lower sides of the valve disc 42 can be communicated with each other.

[0098] Further, the valve assembly 4 further includes a third elastic member 44. The third elastic member 44 is located outside the cover body 1. The upper end of the third elastic member 44 elastically abuts against the bottom of the cover body 1, and the lower end of the third elastic member 44 elastically abuts against the valve disc 42 to force the valve disc 42 to move downward to open the water outlet passage 13 and realize the pouring function. It can be understood that after the stopper portion 411 moves downward to release the valve disc 42, the valve disc 42 can also move downward to open the water outlet passage 13 by relying on its own gravity or other acting forces.

[0099] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
