The lid assembly and liquid heating vessel of some embodiments of the present application will be described below in connection with fig. 1-18.

As shown in fig. 1, 2, 3, 5, 6, 13 and 14, an embodiment of a first aspect of the present utility model provides a cap assembly for covering a top opening of a container body 60 of a liquid heating container, the cap assembly comprising: the lower cover 10, there are at least two mounting seats 110 on the upper surface of the lower cover 10, the mounting seat 110 and lower cover 10 are an integral structure, there are steam inlets 111 communicating with container body 60 in each mounting seat 110; the upper shells 20 are correspondingly covered on the mounting seats 110 one by one, the upper shells 20 and the mounting seats 110 are surrounded to form accommodating cavities, the upper shells 20 are provided with upper air outlets 210, and the upper air outlets 210 are communicated with the steam inlets 111; the movable sealing members 30 are arranged in the accommodating cavities in a one-to-one correspondence, and can move in the accommodating cavities to block or open the upper air outlets 210.

The cover body assembly provided by the embodiment of the aspect comprises a lower cover 10, an upper shell 20 and a movable sealing piece 30, wherein the lower cover 10 is provided with an installation seat 110 integrally formed with the lower cover 10, and the installation seat 110, the upper shell 20 and the movable sealing piece 30 form an anti-toppling assembly of the liquid heating container, and the working principle of the anti-toppling assembly is as follows: the movable sealing member 30 can move to a position blocking the upper air outlet 210 provided on the upper housing 20, so that a closed space is formed inside the blocked anti-toppling component, and the passage of the steam inlet 111 is blocked by the anti-toppling component, so as to prevent water from being spilled out of the steam inlet 111 when the liquid heating container is toppled. The cover body assembly provided by the embodiment of the invention is provided with a plurality of anti-toppling assemblies, and when the liquid heating container is in a toppling state, the movable sealing piece 30 in the anti-toppling assembly positioned at the lower side can seal the upper air outlet 210 positioned at the lower side, so that water is prevented from being spilled out; the movable sealing member 30 in the anti-toppling assembly positioned at the upper side can open the upper air outlet 210 positioned at the upper side, so that the anti-toppling assembly positioned at the upper side keeps a passage, steam can be ensured to flow out of the upper air outlet 210, and the danger caused by that steam in the container body 60 cannot be discharged and the pressure is too high is avoided. Further, by arranging the lower cover 10 and the plurality of mounting seats 110 into an integral structure, the number of parts is reduced, the plurality of mounting seats 110 do not need to be independently processed, the cost of independently processing the plurality of mounting seats 110 is saved, the assembly process between the mounting seats 110 and the lower cover 10 is also saved, the assembly process of the cover body assembly is reduced, the installation efficiency is improved, the assembly time and the assembly cost are reduced, and the production cost of the cover body assembly is greatly reduced. In addition, the mechanical properties of the integrated structure are also good, and the connection strength between the lower cover 10 and the plurality of mounting seats 110 can be improved, so that the mounting seats 110 are prevented from loosening to influence sealing and water resistance, and the quality of products is improved.

It will be appreciated that in the embodiments of the present application, as shown in fig. 7, 8, 9, 10, 11, 12 and 13, the number of the mounting seats 110, the upper housing 20 and the movable seal 30 are equal, and one mounting seat 110, one upper housing 20 and one movable seal 30 constitute one anti-toppling assembly.

Alternatively, the 10 lower cover and the mounting seat 110 are integrally injection molded plastic parts; or a sheet metal part formed by stamping the 10 lower cover and the 110 mounting seat into a whole; or 10 lower cover and mounting base 110 are integrally cast formed metal or glass pieces, etc.

Alternatively, the movable seal 30 is a ball which is not only simple in structure but also can roll rapidly in the seal movable chamber 114 and closely block the upper air outlet 210.

In some embodiments, as shown in fig. 3, 5, 6, 13 and 14, at least two pressure relief ports 120 are further provided on the lower cover 10, each pressure relief port 120 is provided in one of the mounting seats 110, and the pressure relief ports 120 communicate with the container body 60 and the upper air outlet 210.

In these embodiments, by providing the pressure relief opening 120 in the mounting seat 110, the cover assembly can discharge steam through two passages of the pressure relief opening 120 and the steam inlet 111, so that even if water in the container body 60 shakes after pouring, a small amount of water occasionally rushes to the steam inlet 111 and the pressure relief opening 120 located at the upper side under pressure and shaking, since the steam inlet 111 and the pressure relief opening 120 are two passages which are not communicated with each other, even if one passage is plugged, the pressure can still be released through the other passage, the steam in the container body 60 can be released more easily, and the pressure inside and outside the container body 60 can be accelerated to restore balance. The design of the steam inlet 111 and the pressure relief opening 120 effectively realizes water-steam separation, prevents danger caused by large-scale ejection of a mixture of water and steam due to large internal pressure of the container body 60, and reduces the ejection of high-temperature water steam influenced by steam pressure in a hot state of the liquid heating container.
