[0001] The present application relates to the field of household appliances, and in particular to a container cover and a liquid heating container. Background Art

[0002] The container cover of the liquid heating container is provided with a lock buckle, which slides inside the container cover and can lock the container cover to prevent the container cover from being separated from the container body. In the prior art, there is a gap between the lock buckle and the lock hole of the container cover, and the high-temperature steam in the container body can easily enter the container cover through the gap, causing the temperature of the container cover to rise, posing a risk of scalding the user. Utility Model Content

[0003] The present application provides a container cover and a liquid heating container, which can solve the problem in the prior art that high-temperature steam enters the interior of the container cover from the gap between the lock buckle and the lock hole of the container cover.

[0004] A first aspect of the present application provides a container cover, comprising:

[0005] The cover body is provided with a lock hole, and the lock hole is communicated with the outside;

[0006] A lock buckle is slidably connected to the cover body, and when the lock buckle is extended to the outside along the lock hole, the container cover is in a locked state; when the lock buckle is retracted into the cover body, the container cover is in an unlocked state;

[0007] The sealing ring is sleeved on the lock buckle, and the sealing ring and the cover body are abutted and matched along the circumferential direction of the lock buckle.

[0008] In the above scheme, the locking and unlocking of the container cover can be achieved by controlling the movement of the lock: the lock hole is connected to the inside of the cover and the outside respectively, and when the lock button slides along the lock hole to extend out of the outside, the container cover is in a locked state; when the lock button slides along the lock hole to retract into the inside of the cover, the container cover is in an unlocked state. In the above structure, in order to facilitate the lock button to slide inside the cover, there will be a certain gap between the cover and the lock button. When a sealing ring is sleeved on the lock button, the sealing ring and the cover body are abutted and matched along the circumferential direction of the lock button, which can prevent the high-temperature steam or high-temperature liquid in the container from flowing into the cover body through the lock hole through the above gap, ensuring that the temperature of the container cover will not rise, thereby reducing the risk of the container cover scalding the user, and improving the user's use experience and safety. In addition, since the sealing ring is sleeved on the outer periphery of the lock button, during the movement of the lock button, the sealing ring can move synchronously with the lock button, so that the lock button and the cover body always maintain a good sealing effect without hindering the movement of the lock button.

[0009] In a possible design, the lock buckle has a mounting groove arranged around its circumference, and the sealing ring is installed in the mounting groove.

[0010] In the above scheme, the installation groove provides an installation space for the sealing ring, and the side wall of the installation groove can limit the axial movement of the sealing ring along the lock buckle to prevent the sealing ring from falling off the lock buckle during the movement of the lock buckle, thereby improving the installation stability of the sealing ring.

[0011] In a possible design, the cover body is provided with a sealing groove, the sealing ring is slidably connected in the sealing groove, and abuts against the side wall of the sealing groove along the circumference of the lock buckle.

[0012] In the above solution, the shape and size of the sealing groove correspond to those of the sealing ring. During the movement of the lock buckle, the sealing ring can always slide in the sealing groove to ensure the sealing effect of the sealing ring.

[0013] In a possible design, the sealing ring includes a ring body and a sealing portion that are fixedly connected, and the ring body is sleeved on the lock buckle; the sealing portion extends along the radial direction of the sealing ring in a direction away from the lock buckle to abut against the side wall of the sealing groove; along the axial direction of the lock buckle, the size of the sealing portion is smaller than the size of the ring body.

[0014] In the above scheme, the ring body is located in the installation groove, and the sealing part is an annular structure arranged around the ring body, which extends in the radial direction of the sealing ring to form a sealing fit with the side wall of the sealing groove. Specifically, along the axial direction of the lock buckle, the size of the ring body is relatively large, which can increase the connection area between the sealing ring and the lock buckle, thereby ensuring the installation stability between the sealing ring and the lock buckle and preventing the sealing ring from falling off the lock buckle; the size of the sealing part is relatively small, which can reduce the contact area between the sealing ring and the sealing groove, and can reduce the friction between the sealing ring and the sealing groove during the movement of the lock buckle, thereby reducing the resistance of the lock buckle, so as to achieve rapid locking and rapid unlocking of the container cover.

[0015] In a possible design, the cover body is provided with a first limiting groove connected to the locking hole; the lock buckle includes a main body, the main body is slidably arranged in the first limiting groove, and the first limiting groove is used to limit the radial movement of the main body along the lock buckle.

[0016] In the above solution, the first limiting groove matches the shape and size of the main body, which can limit the radial movement of the main body along the lock, and can also limit the rotation of the main body relative to the cover body, thereby improving the stability of the lock during movement.

[0017] In a possible design, the container cover further includes a driving member, which is mounted on the cover body; the driving member is fixedly connected to the lock buckle to drive the lock buckle to extend out along the lock hole to the outside or retract into the cover body.

[0018] In the above scheme, a driving member is provided to drive the lock buckle to slide in the cover body: the driving member is fixedly connected to the lock buckle, and when the driving member moves in the cover body toward the direction close to the lock hole, it can drive the lock buckle to move synchronously, so that the lock buckle extends along the lock hole to the outside, thereby locking the container cover; when the driving member slides in the cover body toward the direction away from the lock hole, it can drive the lock buckle to move synchronously, thereby retracting the lock buckle into the cover body, thereby unlocking the container cover.

[0019] In a possible design, the driving member is provided with a connecting pin, and the locking buckle is provided with a connecting slot, and at least a portion of the connecting pin is accommodated in the connecting slot.

[0020] In the above scheme, the driving member is provided with a connecting pin extending along the axial direction of the lock, and a connecting groove corresponding to the connecting pin is provided on the connecting part of the lock, and at least a part of the connecting pin is accommodated in the connecting groove to realize the fixed connection between the driving member and the lock, thereby ensuring the driving effect of the driving member on the lock.

[0021] In a possible design, the container cover also includes a return spring; a first abutment portion is provided in the cover body, and a second abutment portion is provided in the driving member, and two ends of the return spring abut against the first abutment portion and the second abutment portion respectively.

[0022] In the above scheme, the automatic resetting effect of the lock can be achieved by setting a reset spring. When unlocking the container lid, the user squeezes the gripping portion toward the inside of the lid body, so that the driving member drives the lock to retract into the inside of the lid body. During this process, the second abutting portion moves in a direction close to the first abutting portion, and the reset spring is compressed under the joint action of the first abutting portion and the second abutting portion; when locking the container lid, the force applied by the user on the gripping portion disappears, and the reset spring can drive the driving member and the lock to reset under the action of its own restoring force, so that the lock is extended to the outside along the lock hole.

[0023] In a possible design, the driving member includes a holding portion and a driving portion that are fixedly connected, and the driving portion is fixedly connected to the lock buckle; the cover body is provided with a hollow portion, and at least part of the holding portion extends to the outside along the hollow portion, and the holding portion is used to drive the driving portion to slide within the cover body.

[0024] In the above solution, when the driving member is installed on the cover body, at least part of the gripping portion extends outward along the hollow portion to facilitate the user's use, and the driving portion is located inside the cover body and is used to be fixedly connected with the lock buckle. When the container cover needs to be unlocked, the user can push the gripping portion toward the inside of the cover body to drive the lock buckle to retract into the cover body. By providing the hollow portion, an exposed space is provided for the gripping portion, which is convenient for the user to operate.

[0025] A second aspect of the present application provides a liquid heating container, comprising:

[0026] container body;

[0027] A container cover, wherein the container cover is the container cover described above, and the container cover is buckled on the container body;

[0028] The container cover is locked with the container body through the lock buckle.

[0029] In the above scheme, the container body is used to hold liquid, and when the container cover is buckled on the container body, it can seal the container body to prevent the liquid from splashing out. When the container cover is in a locked state, the lock buckle extends from the lock hole to the outside. If the container cover is lifted upward, the lock buckle will interfere with the container body. At this time, the container cover can be locked with the container body to prevent the container cover from falling off the container body. When the container cover is in an unlocked state, the lock buckle retracts into the cover body, and the user can lift the container cover upward to separate the container cover from the container body.

[0030] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0080] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0081] The present application embodiment provides a container cover 10 for use with a container body 20. Figure 1 and Figure 2 As shown, the container cover 10 includes a cover body 1, a lock buckle 2 and a sealing ring 3. Figure 3 As shown, the cover body 1 is provided with a lock hole 11, which is communicated with the outside world. The lock buckle 2 is slidably connected in the cover body 1. When the lock buckle 2 is extended to the outside world along the lock hole 11, the container cover 10 is in a locked state; when the lock buckle 2 is retracted into the cover body 1, the container cover 10 is in an unlocked state; the sealing ring 3 is sleeved on the lock buckle 2, and the sealing ring 3 and the cover body 1 are abutted and matched along the circumference of the lock buckle 2.

[0082] In this embodiment, the container cover can be locked and unlocked by controlling the movement of the lock buckle 2: the lock hole 11 is connected to the inside of the cover body 1 and the outside respectively. Figure 3 As shown, when the lock buckle 2 slides along the lock hole 11 to extend out of the outside, the container cover 10 is in a locked state; Figure 4 As shown, when the lock buckle 2 slides along the lock hole 11 to retract into the inside of the cover body 1, the container cover 10 is in an unlocked state. In the above structure, in order to facilitate the lock buckle 2 to slide inside the cover body 1, there will be a certain gap between the cover body 1 and the lock buckle 2. When the lock buckle 2 is sleeved with a sealing ring 3, the sealing ring 3 and the cover body 1 are abutted and matched along the circumference of the lock buckle 2, which can prevent the high-temperature steam or high-temperature liquid in the container body 20 from flowing into the inside of the cover body 1 through the lock hole 11 through the above gap, ensuring that the temperature of the container cover 10 will not rise, thereby reducing the risk of the container cover 10 scalding the user, and improving the user's experience and safety of use. In addition, since the sealing ring 3 is sleeved on the outer periphery of the lock buckle 2, during the movement of the lock buckle 2, the sealing ring 3 can move synchronously with the lock buckle 2, so that the lock buckle 2 and the cover body 1 always maintain a good sealing effect without hindering the movement of the lock buckle 2.

[0083] In a specific embodiment, Figure 4 and Figure 5 As shown, the lock buckle 2 has a mounting groove 21 arranged around its circumference, and the sealing ring 3 is installed in the mounting groove 21 .

[0084] In this embodiment, the installation groove 21 provides an installation space for the sealing ring 3. The side wall of the installation groove 21 can limit the axial movement X of the sealing ring 3 along the lock buckle 2 to prevent the sealing ring 3 from falling off the lock buckle 2 during the movement of the lock buckle 2, thereby improving the installation stability of the sealing ring 3.

[0085] Specifically, Figure 4As shown, the lock buckle 2 is provided with a first protrusion 25 and a second protrusion 26 protruding toward the outside along the radial direction Y thereof, the first protrusion 25 and the second protrusion 26 are arranged at intervals along the axial direction X of the lock buckle 2, and the interval therebetween forms a mounting groove 21, and the ends of the first protrusion 25 and the second protrusion 26 are the side walls of the mounting groove 21, which are used to abut against the sealing ring 3 along the axial direction X of the lock buckle 2. Specifically, a plurality of first protrusions 25 and a plurality of second protrusions 26 may be arranged at intervals along the circumference of the lock buckle 2, respectively, to enhance the limiting capability of the mounting groove 21 on the sealing ring 3.

[0086] In a specific embodiment, Figure 6 As shown, the cover body 1 is provided with a sealing groove 12 , and the sealing ring 3 is slidably connected in the sealing groove 12 and abuts against the side wall of the sealing groove 12 along the circumferential direction of the lock buckle 2 .

[0087] In this embodiment, Figure 6 As shown, the cover body 1 is provided with a sealing groove 12 corresponding to the shape and size of the sealing ring 3. Figure 3 and Figure 4 As shown, during the movement of the lock buckle 2, the sealing ring 3 can always slide in the sealing groove 12, that is, the length of the sealing groove 12 in the axial direction X of the lock buckle 2 is greater than the moving distance of the sealing ring 3 in the axial direction X of the lock buckle 2, so as to ensure the sealing effect of the sealing ring 3. Therefore, by providing the sealing groove 12 on the cover body 1, the sealing matching effect between the sealing ring 3 and the cover body 1 can be improved.

[0088] In a specific embodiment, Figure 7 As shown, the sealing ring 3 includes a ring body 31 and a sealing portion 32 that are fixedly connected. The ring body 31 is sleeved on the lock buckle 2. The sealing portion 32 extends along the radial direction Y of the sealing ring 3 in a direction away from the lock buckle 2 to abut against the side wall of the sealing groove 12. Along the axial direction X of the lock buckle 2, the size of the sealing portion 32 is smaller than the size of the ring body 31.

[0089] In this embodiment, the ring body 31 is located in the installation groove 21, and the sealing portion 32 is an annular structure arranged around the ring body 31, which extends along the radial direction Y of the sealing ring 3 to form a sealing fit with the side wall of the sealing groove 12. Specifically, as Figure 8 As shown, along the axial direction X of the lock buckle 2, the size of the ring body 31 is relatively large, which can increase the connection area between the sealing ring 3 and the lock buckle 2, thereby ensuring the installation stability between the sealing ring 3 and the lock buckle 2 and preventing the sealing ring 3 from falling off the lock buckle 2; the size of the sealing portion 32 is relatively small, which can reduce the contact area between the sealing ring 3 and the sealing groove 12, and can reduce the friction between the sealing ring 3 and the sealing groove 12 during the movement of the lock buckle 2, thereby reducing the resistance of the lock buckle 2 to achieve rapid locking and rapid unlocking of the container cover 10.

[0090] In a specific embodiment, Figure 5 and Figure 6 As shown, the cover body 1 is provided with a first limiting groove 13 connected to the locking hole 11, and the lock buckle 2 includes a main body 22, which is slidably arranged in the first limiting groove 13, and the first limiting groove 13 is used to limit the movement of the main body 22 along the radial direction Y of the lock buckle 2.

[0091] In this embodiment, the lock buckle 2 includes a main body 22 and a connecting part 23 that are fixedly connected, and the sealing ring 3 is sleeved on the connecting part 23. Along the axial direction X of the lock buckle 2, the two ends of the first limiting groove 13 are respectively connected with the sealing groove 12 and the outside, and at least part of the connecting part 23 extends into the sealing groove 12. When the lock buckle 2 moves, the connecting part 23 and the main body 22 slide relative to the sealing groove 12 and the first limiting groove 13 respectively.

[0092] Specifically, Figure 5 and Figure 6 As shown, the cross-section of the main body 22 on the axial direction X of the lock buckle 2 is rectangular, and the first limiting groove 13 matches the shape and size of the main body 22, so as to limit the movement of the main body 22 along the radial direction Y of the lock buckle 2, and also limit the rotation of the main body 22 relative to the cover body 1, thereby improving the stability of the lock buckle 2 during movement.

[0093] In a specific embodiment, Figure 1 As shown, the container cover 10 further includes a driving member 4 , which is mounted on the cover body 1 and fixedly connected to the lock buckle 2 to drive the lock buckle 2 to extend along the lock hole 11 to the outside or retract into the cover body 1 .

[0094] In this embodiment, a driving member 4 is provided to drive the lock buckle 2 to slide in the cover body 1: the driving member 4 is fixedly connected to the lock buckle 2, such as Figure 2 As shown, when the driving member 4 moves in the direction close to the lock hole 11 in the cover body 1, it can drive the lock buckle 2 to move synchronously, so that the lock buckle 2 extends out along the lock hole 11 to the outside, thereby locking the container cover 10; Figure 3 As shown, when the driving member 4 slides in the cover body 1 in a direction away from the locking hole 11 , it can drive the lock buckle 2 to move synchronously, so that the lock buckle 2 retracts into the cover body 1 , thereby unlocking the container cover 10 .

[0095] Specifically, Figure 3 and Figure 4 As shown, the driving member 4 is provided with a connecting pin 41 , and the lock buckle 2 is provided with a connecting slot 24 , and at least a portion of the connecting pin 41 is accommodated in the connecting slot 24 .

[0096] In this embodiment, Fig. 9 As shown, the driving member 4 is provided with a connecting foot 41 extending along the axial direction X of the lock buckle 2, as shown in FIG. Figure 5As shown, a connecting slot 24 corresponding to the connecting pin 41 is provided on the connecting portion 23 of the lock 2, and at least a portion of the connecting pin 41 is accommodated in the connecting slot 24 to achieve a fixed connection between the driving member 4 and the lock 2, thereby ensuring the driving effect of the driving member 4 on the lock 2.

[0097] The connection slot 24 can match the shape and size of the connection pin 41 to prevent the connection pin 41 from moving relative to the connection slot 24, thereby improving the connection stability between the driving member 4 and the lock buckle 2.

[0098] like Fig.10 As shown, the connection slot 24 can also be a through hole structure that penetrates along the axial direction Y of the lock buckle 2, and the connection pin 41 passes through the through hole, which can further improve the connection stability between the driving member 4 and the lock buckle 2.

[0099] In a specific embodiment, Figure 5 As shown, the lock buckle 2 is provided with a limiting portion 27 protruding along its radial direction Y, and the driving member 4 is provided with a second limiting groove 45. When the connecting pin 41 extends into the connecting groove 24, the limiting portion 27 can extend into the second limiting groove 45, and the second limiting groove 45 can cooperate with the limiting portion 27 to limit the movement of the lock buckle 2 along the axial direction X of the lock buckle 2 and / or the radial direction Y of the lock buckle 2, thereby further improving the connection stability between the driving member 4 and the lock buckle 2.

[0100] In a specific embodiment, Fig. 9 As shown, the driving member 4 includes a holding portion 43 and a driving portion 44 that are fixedly connected, and the connecting pin 41 is disposed on the driving portion 44, and the driving portion 44 is used to be fixedly connected to the lock buckle 2. Figure 2 As shown, the cover body 1 is provided with a hollow portion 15 , and at least a portion of the gripping portion 43 extends outward along the hollow portion 15 . The gripping portion 43 is used to drive the driving portion 44 to slide in the cover body 1 .

[0101] In this embodiment, when the driving member 4 is installed on the cover body 1, at least part of the gripping portion 43 extends outward along the hollow portion 15 to facilitate user use, and the driving portion 44 is located inside the cover body 1 for fixed connection with the lock buckle 2. Figure 4 As shown, when the container cover 10 needs to be unlocked, the user can push the grip 43 toward the inside of the cover 1 to drive the lock 2 to retract into the cover 1. By providing the hollow portion 15, an exposed space is provided for the grip 43, which is convenient for user operation.

[0102] In a specific embodiment, Figure 3 and Figure 4As shown, the container cover 10 further includes a return spring 5 , a first abutting portion 14 is provided in the cover body 1 , and a second abutting portion 42 is provided in the driving member 4 . Both ends of the return spring 5 abut against the first abutting portion 14 and the second abutting portion 42 , respectively.

[0103] In this embodiment, the automatic reset effect of the lock buckle 2 can be achieved by setting the reset spring 5. Figure 6 As shown, the cover body 1 is provided with a first abutting portion 14, which has a plane abutting against one end of the return spring 5. Similarly, the driving member 4 is provided with a second abutting portion 42, which has a plane abutting against the other end of the return spring 5. Figure 4 As shown, when unlocking the container cover 10, the user presses the gripping portion 43 toward the inside of the cover body 1, so that the driving member 4 drives the lock catch 2 to retract into the inside of the cover body 1. During this process, the second abutting portion 42 moves toward the direction close to the first abutting portion 14, and the return spring 5 is compressed under the joint action of the first abutting portion 14 and the second abutting portion 42; Figure 3 As shown, when the container cover 10 is locked, the force applied by the user on the grip 43 disappears, and the reset spring 5 can drive the driving member 4 and the lock buckle 2 to reset under the action of its own restoring force, so that the lock buckle 2 extends out along the lock hole 11 to the outside.

[0104] like Figure 3 and Figure 4 As shown, a mounting post 46 is provided on one side surface of the second abutment portion 42 facing the first abutment portion 14, and the reset spring 5 is sleeved on the mounting post 46, which can limit the movement of the reset spring 5 in the radial direction Y of the lock buckle 2, thereby avoiding the situation where the movement of the driving member 4 and the lock buckle 2 is affected by the misalignment of the reset spring 5.

[0105] In a specific embodiment, Figure 6 As shown, a guide portion 16 is also provided inside the cover body 1. Fig. 9 As shown, a guide matching portion 47 matching with the guide portion 16 is provided on the driving portion 44. Along the height direction of the cover body 1, the top wall of the guide matching portion 47 abuts against the bottom wall of the guide portion 16. When the driving member 4 slides in the cover body 1, the guide matching portion 47 can be slidably matched with the guide portion 16, and the guide portion 16 can limit the movement of the driving member 4 along the height direction of the cover body 1, thereby improving the stability of the movement process of the driving member 4.

[0106] like Figure 1 and Figure 2 As shown, the cover body 1 includes an upper cover 1a, a middle cover 1b and a lower cover 1c which are arranged in sequence along the height direction of the container cover 10, the hollow portion 15 is arranged on the upper cover 1a, the lock hole 11, the sealing groove 12, the first limiting groove 13, the first abutment portion 14 and the guide portion 16 are all arranged on the middle cover 1b, and the driving member 4 is installed in the space enclosed by the upper cover 1a and the middle cover 1b.

[0107] The present application also provides a liquid heating container, such as Figure 1 As shown, the liquid heating container includes a container body 20 and the container cover 10 described in the above embodiments. The container cover 10 is buckled on the container body 20, and the container cover 10 is locked with the container body 20 through a lock 2.

[0108] In this embodiment, the container body 20 is used to hold liquid. When the container cover 10 is buckled on the container body 20, it can seal the container body 20 to prevent the liquid from splashing out. When the container cover 10 is in a locked state, the lock buckle 2 extends from the lock hole 11 to the outside. If the container cover 10 is lifted upward, the lock buckle 2 will interfere with the container body 20. At this time, the container cover 10 can be locked with the container body 20 to prevent the container cover 10 from falling off the container body 20. When the container cover 10 is in an unlocked state, the lock buckle 2 retracts into the cover body 1, and the user can lift the container cover 10 upward to separate the container cover 10 from the container body 20.

[0109] In addition, the liquid heating container also includes a sealing member 30, such as Figure 1 As shown, the sealing member 30 is sleeved on the outer periphery of the middle cover 1b. When the container cover 10 is buckled onto the container body 20, the sealing member 30 can be sealed and connected to the container body 20, thereby preventing the liquid inside the container body 20 from overflowing.

[0110] In the present application, the driving member 4, the lock buckle 2, the sealing ring 3 and the return spring 5 together constitute a locking assembly. Figure 1 and Figure 2 As shown, the two locking components are symmetrically arranged along the axis of the container cover 10, that is, there are two lock buckles 2 to lock the container cover 10 and the container body 20 at the same time, further improving the connection reliability between the container cover 10 and the container body 20 and preventing the two from falling off during use.

[0111] In the present application, when installing the container cover 10 on the container body 20, the user can squeeze the gripping parts 43 of the two driving members 4 in opposite directions at the same time to drive the two lock buckles 2 to retract into the cover body 1 at the same time to unlock the container cover 10, and then snap the container cover 10 onto the container body 20 and then let go, so that the two lock buckles 2 are respectively reset under the action of the two reset springs 5, thereby locking the container cover 10 with the container body 20. The disassembly method of the container cover 10 is similar to the installation method, firstly, the lock buckle 2 is driven by the driving member 4 to move, so that the container cover 10 is unlocked, and then the container cover 10 is removed from the container body 20 and then let go, so that the two lock buckles 2 are reset.

[0112] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. 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.
