[0026] The first matching piece slides and is positionally matched with the first guide groove, and the second matching piece slides and is positionally matched with the second guide groove.

[0027] Furthermore, an elastic return component is provided between the first lock core and the second lock core.

[0028] Furthermore, the elastic return assembly comprises:

[0029] A column spring, wherein the column spring is arranged between the first lock core and the second lock core;

[0035] Furthermore, the first guide arm and the second guide arm are both bent toward the direction close to the column spring to form a protrusion;

[0036] The protrusion corresponds to a middle portion of the column spring.

[0037] Furthermore, the first lock core and the second lock core are both provided with mounting grooves, and both ends of the column spring are respectively connected to the corresponding mounting grooves;

[0083] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0084] In the description of the present invention, it should be noted that the terms "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0085] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0086] It should be additionally explained here that, in the present embodiment, the liquid heating container may be an electric kettle, a health kettle or other liquid heating containers.

[0087] like Figure 2 , Figure 4 and Figure 5As shown, the present embodiment provides a container cover, which includes a cover body 1 and a first lock core 3 and a second lock core 4 which are centrally symmetrically arranged, and a lock tongue 2 is arranged on the first lock core 3 and the second lock core 4, wherein both slide and limit with the cover body 1. Further, the container cover also includes a first matching piece 9 and a second matching piece 10. Specifically, the first matching piece 9 and the second matching piece 10 are respectively connected to the end surfaces opposite to the first lock core 3 and the second lock core 4, and the first matching piece 9 and the second matching piece 10 are staggered, wherein the first matching piece 9 and the second matching piece 10 both slide and limit with the cover body 1. The length of the first lock core 3 in the sliding direction can be increased by the first matching piece 9, and the length of the second lock core 4 in the sliding direction can be increased by the second matching piece 10, thereby correspondingly increasing the length of the first lock core 3 and the second lock core 4. Since under the same limit spacing, the longer the guide distance, the smaller the angle at which the first lock core 3 and the second lock core 4 can be deflected, this structural design can achieve smooth opening regardless of whether the force applied by the user to the lock switch is in the middle of the lock switch, thereby improving the stability of the first lock core 3 and the second lock core 4 during the sliding process, and reducing or even avoiding the tendency of the first lock core 3 and the second lock core 4 to deflect during the sliding process; at the same time, the first matching piece 9 and the second matching piece 10 are staggered. This structural design makes the first matching piece 9 and the second matching piece 10 spaced and staggered, greatly improving the utilization rate of the space, ensuring that the first lock core 3 and the second lock core 4 can be reasonably distributed in a smaller space of the cover body 1, and at the same time, increasing the guide distance between the first lock core 3 and the second lock core 4, and the design is simple and ingenious.

[0088] In this embodiment, the first mating piece 9 and the second mating piece 10 can also slide and limit each other. This design has the same effect as that of both of them sliding and limiting each other with the cover body 1, and will not be repeated here. In particular, for ease of assembly, preferably, the first mating piece 9 and the second mating piece 10 both slide and limit each other with the cover body 1.

[0089] It should be explained here that, in the present embodiment, the first matching piece 9 and the second matching piece 10 are staggered to each other, which means that the two are arranged at intervals, that is, any first matching piece 9 and any second matching piece 10 are not on the same straight line.

[0090] like Figure 1 and Figure 4 As shown, it needs to be explained here that the guide distance refers to the distance from the guide point on the cover body 1 to the end face of the first lock core 3 (second lock core 4) facing away from the lock tongue 2, wherein the guide distance in the prior art solution is L1, and the guide distance in this embodiment is L2.

[0091] The first matching piece 9 can be connected to the first lock core 3 by various means such as bonding and clamping. In order to ensure the strength of the connection structure of the first matching piece 9, in the present embodiment, the first lock core 3 extends outward to form the first matching piece 9, that is, the first lock core 3 and the first matching piece 9 are formed integrally.

[0092] like Figure 2 , Figure 5 and Figure 6 As shown, the first lock core 3 and the second lock core 4 are respectively slidably connected to the cover body 1, and both are limitedly matched with the cover body 1. Specifically, in the present embodiment, the cover body 1 is recessed to form a slide groove, and the first lock core 3 and the second lock core 4 are provided with protrusions, which are slidably connected with the slide groove and limitedly matched with each other; or a second slide 8 is provided on the cover body 1, wherein the end surface of the cover body 1 extends outward to form the second slide 8, and the first lock core 3 and the second lock core 4 are slidably connected with the second slide 8 and limitedly matched. Furthermore, for the convenience of assembly, it is preferably that the first lock core 3 and the second lock core 4 are slidably connected with the second slide 8 and limitedly matched.

[0093] like Figure 4 , Figure 5 and Figure 7 As shown, the first mating piece 9 can be one or more, and the second mating piece 10 can be one or more. Further, each first mating piece 9 is connected to the first lock core 3, and each second mating piece 10 is connected to the second lock core 4, and the number of first mating pieces 9 and second mating pieces 10 is equal. In order to be able to assemble the first lock core 3 and the second lock core 4 in a smaller space, in this embodiment, at least one second mating piece 10 is arranged between adjacent first mating pieces 9. This structural design makes the first mating piece 9 and the second mating piece 10 spaced and staggered, which greatly improves the utilization rate of the space and ensures that the first lock core 3 and the second lock core 4 can be reasonably distributed in a smaller space of the cover body 1. At the same time, the guide distance between the first lock core 3 and the second lock core 4 is also increased. The design is simple and ingenious. In addition, multiple first mating pieces 9 increase the guide points of the first lock core 3, and multiple second mating pieces 10 increase the guide points of the second lock core 4, so that the lock tongue 2 can stably achieve contraction and extension.

[0094] like Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, in order to facilitate processing and manufacturing and improve production efficiency, in this embodiment, the first matching piece 9 and the second matching piece 10 correspond to each other one by one and are arranged in a central symmetric manner, that is, the first matching piece 9 is arranged in a central symmetric manner and completely overlaps with the second matching piece 10. At the same time, since the first lock core 3 and the second lock core 4 are also arranged in a central symmetric manner, in actual production, it is only necessary to produce the first lock core 3 connected with the first matching piece 9 or the second lock core 4 connected with the second matching piece 10, which simplifies the production process. While ensuring the stable sliding of the first lock core 3 and the second lock core 4, the structural composition can also be simplified. Preferably, there are two first matching pieces 9 and two second matching pieces 10.

[0095] like Figure 4 As shown, further, in the present embodiment, the first lock core 3 has a first sliding surface 12 and a second sliding surface 13. Along the sliding direction perpendicular to the first lock core 3, the distance between one first mating piece 9 and the first sliding surface 12 is S1, and the distance between the other first mating piece 9 and the second sliding surface 13 is S2. S1 and S2 are not equal. The inequality of S1 and S2 enables the first mating piece 9 to completely overlap with the second mating piece 10. The structural design is reasonable and ingenious.

[0096] like Figure 4 As shown, in order to better ensure the stability of the first lock core 3 and the second lock core 4 during the sliding process and reduce the angle when deflection occurs, specifically, the distance value between the lock tongue 2 on the first lock core 3 and the first matching piece 9 is D1, the distance value between the lock tongue 2 on the second lock core 4 and the second matching piece 10 is D2, and the distance between the lock tongue 2 on the first lock core 3 and the lock tongue 2 on the second lock core 4 is D3, wherein D1 and D2 are not less than half of D3, and through D1+D2≤D3 / 2, the guide distance of the first lock core 3 (second lock core 4) can be extended as much as possible, thereby ensuring the stability and smoothness of the first lock core 3 (second lock core 4) during the sliding process, thereby improving the user's experience.

[0097] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in order to achieve stable sliding of the first matching piece 9 and the second matching piece 10, a first slideway 5 is provided on the cover body 1, and the first matching piece 9 and the second matching piece 10 slide and limit with the first slideway 5 respectively, and the first slideway 5 can ensure that the moving tracks of the first matching piece 9 and the second matching piece 10 are not deviated. Further, as shown in FIG. Figure 2 , Figure 3 and Figure 4As shown, in order to better ensure the stable sliding of the first mating piece 9 and the second mating piece 10, specifically, in the present embodiment, a plurality of first slideways 5 are arranged on the cover body 1, the first mating piece 9 slides and is limitedly matched with a part of the first slideway 5, and the second mating piece 10 slides and is limitedly matched with another part of the first slideway 5, by respectively arranging the first mating piece 9 and the second mating piece 10 in different first slideways 5, so as to realize the staggered arrangement of the first lock core 3 and the second lock core 4, it is ensured that the first lock core 3 and the second lock core 4 are assembled in a smaller space of the cover body 1, and at the same time, the first slideway 5 also has a guiding and limiting function, and under the joint action with the second slideway 8, it is possible to better ensure that the movement process of the first lock core 3 and the second lock core 4 does not deflect.

[0098] The first slideway 5 can be formed by the cover body 1 being concave or convex outward. In the present embodiment, the specific formation method of the first slideway 5 is not limited.

[0099] like Figure 7 As shown, in the present embodiment, another sliding limiting method of the first mating piece 9 and the extension rib of the second lock core 4 is also provided. Specifically, the first lock core 3 is provided with a plurality of first guide grooves 31, and the second lock core 4 is provided with a plurality of second guide grooves 41. The first mating piece 9 slides and limits with the first guide groove 31, and the second mating piece 10 slides and limits with the second guide groove 41. The first guide groove 31 and the second guide groove 41 have the same advantages as the first slide 5, which have been clearly explained in the previous text and will not be repeated here.

[0100] like Figure 2 , Figure 4 and Figure 5 As shown, further, in order to realize automatic resetting of the first lock core 3 and the second lock core 4 after opening and improve the practicality of the container cover, in the present embodiment, an elastic return component 6 is arranged between the first lock core 3 and the second lock core 4. The elastic return component 6 can retract the lock tongue 2 after being driven to be opened to the initial position. At the same time, the first lock core 3 and the second lock core 4 are driven by the elastic return component 6 so that the lock tongue 2 can be more stably connected to the lock hole, thereby improving the stability of the lock tongue 2.

[0101] like Figure 2 , Figure 4 and Figure 5 As shown, specifically, the elastic return assembly 6 includes an elastic return part, and an elastic return part is arranged between the first lock core 3 and the second lock core 4. In the present embodiment, when the first lock core 3 and the second lock core 4 are opened, at this time, the elastic return part is deformed and elastic under the movement of the first lock core 3 and the second lock core 4. When the lock tongue 2 is opened and the user releases the lock switch, the first lock core 3 and the second lock core 4 drive the corresponding lock tongue 2 to reset under the action of the elastic return part.

[0102] The elastic return member may be a clockwork spring, a torsion spring or the like. In the present embodiment, in order to facilitate the assembly of the elastic return member, preferably, the elastic return member is a column spring 61 .

[0103] like Figure 2 , Figure 5 and Figure 6 As shown, further, the elastic return assembly 6 also includes a guide member 62, which is connected to the cover body 1, and the column spring 61 is deformed along the sliding direction of the first lock core 3 (second lock core 4) under the restriction of the guide member 62. Due to the action of the guide member 62, the column spring 61 can ensure stable deformation in the axial direction, thereby ensuring the smooth opening and closing process of the first lock core 3 and the second lock core 4.

[0104] like Figure 2 and Figure 6 As shown, the guide member 62 can be a rod-mounted structure, and the column spring 61 is sleeved on the guide member 62 to achieve deformation along the sliding direction of the first lock core 3 (second lock core 4). To facilitate the structural setting of the guide member 62 and the connection with the cover body 1, and at the same time, to facilitate the assembly of the column spring 61, in the present embodiment, specifically, the guide member 62 includes a first guide arm 621 and a second guide arm 622, and a guide track 7 is formed between the first guide arm 621 and the second guide arm 622, wherein the column spring 61 is arranged in the guide track 7, and the column spring 61 is deformed along the sliding direction of the first lock core 3 (second lock core 4) under the restriction of the guide track 7.

[0105] like Figure 2 and Figure 6 As shown, the first guide arm 621 and the second guide arm 622 can be straight structures, wherein, in order to prevent the column spring 61 from contacting the first guide arm 621 or the second guide arm 622 and making abnormal noise during the compression process, in the present embodiment, the first guide arm 621 and the second guide arm 622 are both bent toward the direction close to the column spring 61 to form a protrusion 621a, and the protrusion 621a corresponds to the middle part of the column spring 61. Since the middle position of the column spring 61 is more likely to deviate from the axial direction than the two ends during the compression process of the column spring 61, the protrusion 621a can inhibit the middle position of the column spring 61 from deviating from the axial direction. At the same time, the two ends of the first guide arm 621 and the second guide arm 622 are farther away from the column spring 61 than the protrusion 621a. Therefore, the setting to prevent the two ends of the column spring 61 from contacting the first guide arm 621 or the second guide arm 622 can be reduced as much as possible, thereby preventing the column spring 61 from contacting the first guide arm 621 or the second guide arm 622 and making abnormal noise during the compression or recovery process.

[0106] Furthermore, the protrusion 621a is formed by bending the first guide arm 621 and the second guide arm 622 in a direction close to the column spring 61. Therefore, the parts where the two ends of the first guide arm 621 and the second guide arm 622 are connected to the protrusion 621a can improve the structural strength of the protrusion 621a, thereby ensuring that the column spring 61 is compressed along the axial direction.

[0107] It should be additionally explained here that in order to avoid the side walls of the first slide 5, the first guide arm 621 and the second guide arm 622 from shrinking in thickness during use, which would lead to a decrease in the stability of the first lock core 3 and the second lock core 4, in this embodiment, preferably, the wall thickness of the side walls of the first slide 5, the first guide arm 621 and the second guide arm 622 is between 0.8 and 1 mm.

[0108] like Figure 2 As shown, further, in order to prevent the first lock core 3 and the second lock core 4 from moving too far, resulting in excessive compression of the column spring 61 and friction with the guide member 62, in the present embodiment, the first lock core 3 and the second lock core 4 are both provided with mounting grooves 32, and the two ends of the column spring 61 are respectively connected to the corresponding mounting grooves 32, and projected along the deformation direction of the column spring 61, the projection of the protrusion 621a is located within the projection of the mounting groove 32, and when the mounting groove 32 moves to conflict with the protrusion 621a, the first lock core 3 and the second lock core 4 stop moving. At the same time, this structural design can also avoid the phenomenon of jamming and collision caused by excessive movement of the first lock core 3 and the second lock core 4, and better improve the stability of the movement of the first lock core 3 and the second lock core 4, wherein the mounting groove 32 slides and limits with the guide rail 7.

[0109] like Figure 2 and Figure 3 As shown, in this embodiment, the container cover also includes a top cover 11, which is detachably connected to the cover body 1, and the two enclose a accommodating cavity, and the first lock core 3, the second lock core 4, the first matching piece 9 and the second matching piece 10 are all located in the accommodating cavity, wherein a first switch hole 111 and a second switch hole 112 are provided on the top cover 11, wherein the first lock core 3 corresponds to the first switch hole 111, and the second lock core 4 corresponds to the second switch hole 112, and the user can realize the opening and closing of the first lock core 3 and the second lock core 4 through the first switch hole 111 and the second switch hole 112.

[0110] like Figure 2 and Figure 3 As shown, further, in order to improve the aesthetics of the container cover, in this embodiment, the portion between the first switch hole 111 and the second switch hole 112 covers the space area between the first lock core 3 and the second lock core 4. This structural design makes the entire container cover look symmetrical from the outside, and at the same time, it can also protect the internal components of the container cover.

[0111] This embodiment also provides a liquid heating container, which includes a container body provided with a lock hole and a container cover as described in any one of the above embodiments, wherein the container cover is hinged to the container body, and the locking tongue 2 corresponds to the lock hole.
