Along with the popularization of electric kettles, the performances and the use comfort of the electric kettles are more and more valued by people. Such as: the lid of the existing electric kettle is generally opened upwards, which requires that the place for receiving water must have enough height space, otherwise the water cannot be received smoothly. However, the water receiving area of devices such as a water dispenser is limited in height, and cannot accommodate an electric kettle with an opened kettle cover, and a user can only take water from other containers for multiple times and then pour the water into the electric kettle, which is very inconvenient, so that the use process is very unpleasant. In addition, the opening and closing manner of the pot lid is also complicated, such as: the kettle lid can not be automatically maintained at the lid opening position after being opened, and the kettle lid needs to be manually maintained by a user, so that the kettle lid is inconvenient.

Disclosure of Invention

In order to solve at least one of the above technical problems, an object of the present invention is to provide a liquid heating container.

In order to achieve the above object, the present invention provides a liquid heating container comprising: the kettle body is provided with an accommodating cavity with one open end; the handle is arranged on the side part of the kettle body, and the top of the handle is provided with a detachable mounting seat; the kettle cover is fixedly provided with a poking part extending outwards, the poking part is rotatably connected with the mounting seat through a rotating shaft extending along the vertical direction and can drive the kettle cover to rotate around the rotating shaft in the plane where the kettle cover is located so as to open the opening end of the accommodating cavity; the limiting piece is movably arranged on the kettle cover and can move downwards to stop against the outer wall surface of the kettle body when the kettle cover is opened to a preset angle so as to limit the reverse rotation and covering of the kettle cover; the cover closing key is movably arranged on the kettle cover and can drive the limiting piece to move upwards so as to relieve the stopping of the limiting piece on the kettle body; the elastic locking piece is limited between the shifting part and the mounting seat, and can drive the kettle cover to reversely rotate to cover the opening end of the accommodating cavity when the cover closing key relieves the stopping of the limiting piece on the kettle body.

According to the liquid heating container provided by the invention, the rotating shaft extends along the vertical direction, so that the kettle cover can be opened towards the side, the height of the liquid heating container after the cover is opened is reduced, and the problem that the liquid heating container such as an electric kettle is inconvenient due to overhigh height caused by the fact that the cover is opened upwards in the prior art is solved; the kettle cover is provided with a movable limiting piece which can stop against the outer wall surface of the kettle body to maintain the uncovering state of the kettle cover without manual maintenance of a user, so that the use comfort of the user is improved; meanwhile, the elastic locking piece enables the liquid heating container to be automatically closed, so that the kettle cover can be stably and stably covered on the kettle body in a natural state without random deflection, semi-automatic control of the kettle cover is realized, and the use convenience of a user is improved; in addition, the mounting seat is detachably arranged at the top of the handle (for example, the mounting seat is fixed at the top of the handle through fasteners such as screws), so that when the mounting seat is damaged, only the mounting seat can be replaced without replacing the whole handle, and the size and the specific structure of the mounting seat can be reasonably designed according to different types of liquid heating containers.

Specifically, in a cover closing state, the elastic locking piece is in a natural state, namely, no elastic deformation occurs, when the cover is opened, the tail end (namely, the shifting part) of the kettle cover is continuously shifted, and the shifting part rotates around the rotating shaft to drive the kettle cover to be slowly opened; in the opening process of the kettle cover, the elastic locking piece generates elastic deformation to store elastic potential energy; when the kettle cover is opened to a preset angle, the limiting part on the kettle cover moves downwards and stops against the outer wall surface of the kettle body, so that the kettle cover is prevented from being reversely rotated and covered under the driving of the elastic locking part, a user can maintain the uncovering state of the kettle cover without abutting against the shifting part, and the use comfort level of the user is greatly improved; when the cover is closed, the cover closing key is driven to remove the resisting action of the limiting part on the kettle body, the elastic locking part releases elastic potential energy to reset, and the kettle cover is driven to rotate reversely until the cover closes the opening end of the accommodating cavity. The rotating shaft extends along the vertical direction, so that the kettle cover rotates along the horizontal direction, and the lateral opening of the kettle cover is realized; the limiting piece is matched with the kettle body, so that the uncapping state of the kettle cover can be maintained, and great convenience is brought to a user; meanwhile, the elastic locking piece enables the kettle cover to be automatically closed, and the kettle cover does not need to be manually turned to return by a user, so that the automation degree of the liquid heating container is improved, and the use comfort of the user is further improved.

Such as: when a user takes the kettle to receive water from the water dispenser, the kettle cover is opened towards the side, and the electric kettle with the kettle cover arranged below the water receiving area of the water dispenser can be installed at the height to directly receive water, so that the water dispenser is very convenient; after water is received, the cover closing key is driven to close the cover.

It should be noted that the pot lid in the present application may be a single-layer structure, or may be a multi-layer structure, such as an assembly including an upper lid, an inner lid, and a lower lid.

As for the preset angle, that is, the angle of horizontal rotation around the rotation axis when the pot lid is completely opened, the specific value is not limited, for example, the angle may be 45 ° -90 ° (45 °, 60 °, 75 °, 90 °), and the like, and certainly may be greater than 90 °, which is determined according to the product structure and the user requirement in the actual production process.

In addition, the liquid heating container in the above technical solution provided by the present invention may further have the following additional technical features:

in the technical scheme, an installation space and an avoidance hole communicated with the installation space and penetrating through the lower surface of the kettle cover are arranged in the kettle cover, and the limiting part comprises a limiting part and a stopping part, wherein the limiting part is limited in the installation space and is lower than the installation space in height, and the stopping part is connected with the limiting part and longitudinally penetrates through the avoidance hole to stop against the outer wall surface of the kettle body; the cover closing key can drive the limiting part to move upwards, so that the stopping part retracts into the avoiding hole, and stopping of the kettle body is relieved.

The limiting part comprises a limiting part and a stopping part, the limiting part is limited in the mounting space, and the limiting part is prevented from being separated from the kettle cover; the height of the limiting part is lower than that of the mounting space, so that the limiting part can move up and down in the mounting space, and the limiting part can move up and down relative to the kettle cover; the stopping part penetrates through the avoiding hole, so that the lower end of the limiting part can protrude out of the kettle cover, and the kettle body is stopped to play a limiting role.

The specific process is as follows: in the cover opening process, when the end part of the abutting part crosses the inner wall surface of the kettle body, the limiting part moves downwards under the action of gravity, so that the lower end of the abutting part protrudes out of the avoiding hole, the shifting part is loosened at the moment and influenced by the elastic locking part, the shifting part has the tendency of reverse rotation, and the side surface of the abutting part abuts against the outer wall surface of the kettle body and cannot rotate continuously, so that the effective limiting effect is achieved on the kettle cover, the reverse buckling of the kettle cover is avoided, and the kettle cover can be automatically kept in a cover opening state; when the kettle lid is closed, the lid closing key is triggered, the lid closing key drives the limiting part to move upwards, the stopping part also moves upwards and retracts into the avoiding hole, the stopping action on the kettle body is relieved, and the kettle lid can rotate to cover the opening end of the containing cavity under the action of the elastic locking piece.

In the technical scheme, a first guide inclined plane is arranged at one end, close to the cover closing key, of the limiting part, and the first guide inclined plane is inclined from top to bottom and is inclined towards the direction far away from the cover closing key; when the cover closing key is driven, thrust can be applied to the first guide inclined plane, so that the limiting part moves upwards.

Spacing portion is close to the one end that closes the lid key and is equipped with first direction inclined plane, and first direction inclined plane from top to bottom inclines, and to keeping away from the direction slope that closes the lid key, promptly: the upper end of the first guide inclined plane is closer to the cover closing key than the lower end of the first guide inclined plane. Therefore, when the cover closing key is driven, the thrust applied to the first guide inclined plane can generate an upward component force, and the stop part in the avoiding hole limits the movement of the limiting part in the horizontal direction, so that the limiting part can only move upwards along the vertical direction under the driving of the cover closing key, and the stop part retracts into the avoiding hole to relieve the stop of the kettle body. Therefore, the first guide inclined plane can convert the movement of other structures (driving structures or transmission structures) in the horizontal direction into the movement of the limiting part in the vertical direction, and the device is ingenious in conception and simple in structure.

As for the structure that promotes first direction inclined plane, it must with first direction inclined plane direct contact, just can promote spacing portion upward movement, for example: the first guide inclined plane and the second guide inclined plane can be inclined planes parallel to each other and are attached to each other; the limiting part can also be a non-inclined surface, such as a vertical surface lower than the upper end of the first guide inclined surface, and the limiting part can also be pushed to move upwards.

In the technical scheme, the kettle cover is further provided with a guide hole communicated with the mounting space and penetrating through the upper surface of the kettle cover, and the cover closing key is mounted in the guide hole and can move up and down along the central axis of the guide hole; the liquid heating container also comprises a transmission piece which is limited in the installation space and can slide in the installation space in a reciprocating manner, one end of the transmission piece is abutted against the lower end of the cover closing key, and the other end of the transmission piece is abutted against the first guide inclined plane; when the cover closing key is pressed, the transmission piece is driven to slide towards the direction close to the limiting piece, so that the transmission piece pushes the limiting piece to move upwards, and the stopping of the stopping part on the kettle body is relieved.

In the above technical solution, a second guiding inclined plane is provided at the lower end of the cover closing key and/or at an end of the transmission member close to the cover closing key, and the second guiding inclined plane is inclined from top to bottom and is inclined in a direction away from the limiting member; and/or one end of the transmission piece close to the limiting part is provided with a third guide inclined plane parallel to the first guide inclined plane; and/or the upper surface of the kettle cover is provided with a guide post, and the guide post is internally provided with the guide hole; and/or the central axis of the guide hole coincides with the central axis of the kettle body.

The cover is also provided with a guide hole in the vertical direction, and the cover closing key is arranged in the guide hole, so that the cover closing key can move up and down relative to the kettle cover, the cover closing key can be driven by pressing the cover closing key, the use habit of a user is relatively met, and the operation and the use of the user are convenient; correspondingly, a transmission part needs to be additionally arranged between the cover closing key and the limiting part, the transmission part is driven to slide towards the direction close to the limiting part through the downward movement of the cover closing key, and then the limiting part is driven to move upwards through the sliding of the transmission part in the horizontal direction.

Further, the lower extreme and/or the driving medium that close the lid key are close to the one end that closes the lid key and are equipped with second direction inclined plane, and second direction inclined plane from top to bottom inclines, and inclines to the direction of keeping away from the locating part, promptly: the upper end of the second guide inclined plane is closer to the limiting part than the lower end of the second guide inclined plane. Therefore, when the cover closing key is pressed, the thrust applied to the second guide inclined plane can generate component force in the horizontal direction, and the gravity and the mounting space of the transmission part limit the movement of the transmission part in the vertical direction, so that the transmission part can only move towards the direction close to the limiting part along the horizontal direction under the driving of the cover closing key, and further the limiting part is pushed to move upwards to drive the stopping part to retract into the avoiding hole so as to remove the stopping of the kettle body. Therefore, the second guide inclined plane can convert the movement in the vertical direction of the cover closing key into the movement in the horizontal direction of the transmission part, the design is ingenious, the structure is simple, and the replacement and the maintenance are convenient.

Preferably, the lower extreme that closes the lid key and the one end that the driving medium is close to closing the lid key all are equipped with the second direction inclined plane, are showing like this and have increased the area of contact who closes lid key and driving medium for the motion of closing lid key and driving medium is more steady. When only one of the lower end of the cover closing key and one end of the transmission piece close to the cover closing key is provided with the second guide inclined surface, the other one of the lower end of the cover closing key and the end of the transmission piece close to the cover closing key can be ensured to be directly contacted with the second guide inclined surface, namely the contact part needs to be lower than the upper end of the second guide inclined surface. Of course, a transmission part is not required to be arranged, the limiting part is directly driven to move upwards by the cover closing key, the cover closing key is horizontally installed in the installation space, and the limiting part can be pushed to move upwards when the cover closing key horizontally slides in the installation space.

The end of the transmission part close to the limiting part is provided with a third guide inclined plane which is parallel to the first guide inclined plane, so that the contact area between the transmission part and the limiting part is increased remarkably, and the movement of the transmission part and the limiting part is more stable.

The upper surface of pot lid is equipped with the guide post, is equipped with the guiding hole in the guide post, has increased the length of closing the lid key like this, and then has increased the spacing length in the pot lid of closing the lid key to avoid closing the lid key too short condition emergence of droing from the pot lid easily.

Specifically, in a natural state, the elastic member is in a natural state, so that the limiting member is located at a lower position; in the process of opening the cover, when the limiting piece moves upwards to cross the kettle body, the elastic piece is compressed, so that the elastic piece stores elastic potential energy; when the limiting part crosses the kettle body and reaches the outer side of the kettle body, the elastic part releases elastic potential energy, so that the limiting part can move downwards quickly to stop against the outer wall surface of the kettle body and stably keep the limiting part at a lower position, and the use reliability of the limiting part is improved.

Preferably, the elastic part is a spring, the elasticity of the spring is good, the materials are easily obtained, and the price is low. Of course, the elastic element is not limited to a spring, and can also be in other forms such as a spring plate; or, the elastic member may not be provided, and the gravity of the limiting member provides the power for the limiting member to move downward, and the material of the limiting member may be cast iron or other material with relatively high density.

In the above technical scheme, a groove is arranged at the top of the limiting part, and the lower end of the elastic part is located in the groove.

The top of spacing portion is equipped with the recess, and the lower extreme of elastic component is located the recess, and the recess has played better limiting displacement to the elastic component to avoid the elastic component to take place the circumstances such as slope, aversion, skew, thereby improved the use reliability of elastic component.

The torsion spring is sleeved on the rotating shaft, so that the main body part of the torsion spring is effectively limited, the position of the torsion spring is not changed in the processes of opening and closing the cover, and the use reliability of the torsion spring is further ensured; and the torsion spring and the kettle cover share one rotating shaft, so that the cover opening structure of the liquid heating container is simplified. Of course, the torsion spring and the pot lid may not share one rotating shaft, but may be separately disposed.

The digging arm of torsional spring is spacing on the portion of stirring, and the fixed arm is spacing on the mount pad, and at the in-process of uncapping and closing the lid, the relative mount pad of portion of stirring rotates for the digging arm of torsional spring also takes place position change relative to the fixed arm, thereby produces elastic deformation, and then has guaranteed that the pot lid is opening in the rotation and the in-process that the rotation was closed, and the torsional spring keeps synchronous deformation, and then has guaranteed the use reliability of torsional spring.

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

A liquid heating vessel according to some embodiments of the present invention is described below with reference to fig. 1 to 16.

As shown in fig. 1 to 16, the present invention provides a liquid heating container, comprising: a kettle body 20, a handle 30, a kettle cover 10, a limit piece 80, a cover closing key 70 and an elastic locking piece.

Specifically, the kettle body 20 has a containing cavity with one end open; the handle 30 is arranged at the side part of the kettle body 20, and the top of the handle 30 is provided with a detachable mounting seat 40; a poking part 11 extending outwards is fixedly arranged on the kettle cover 10, the poking part 11 is rotatably connected with the mounting seat 40 through a rotating shaft 42 extending along the vertical direction, and can drive the kettle cover 10 to rotate around the rotating shaft 42 in the plane where the kettle cover 10 is located so as to open the open end of the accommodating cavity; the limiting piece 80 is movably mounted on the kettle lid 10 and can move downwards to stop against the outer wall surface of the kettle body 20 when the kettle lid 10 is opened to a preset angle so as to limit the reverse rotation and covering of the kettle lid 10; the lid closing key 70 is movably mounted on the kettle lid 10 and can drive the limiting member 80 to move upwards so as to release the stopping of the limiting member 80 on the kettle body 20; the elastic locking piece is limited between the toggle part 11 and the mounting seat 40, and can drive the kettle lid 10 to rotate reversely to cover the opening end of the accommodating cavity when the lid closing key 70 releases the stopping of the limiting piece 80 on the kettle body 20.

According to the liquid heating container provided by the invention, the rotating shaft 42 extends along the vertical direction, so that the kettle cover 10 can be opened towards the side, the height of the liquid heating container after being opened is reduced, and the problem that the liquid heating container such as an electric kettle is inconvenient due to overhigh height caused by the fact that the liquid heating container is opened upwards in the prior art is solved; the kettle lid 10 is provided with a movable limiting piece 80, and the limiting piece 80 can be stopped against the outer wall surface of the kettle body 20 to maintain the opening state of the kettle lid 10 without manual maintenance of a user, so that the use comfort of the user is improved; meanwhile, the elastic locking piece enables the liquid heating container to be automatically closed, so that the kettle cover 10 can be stably and stably closed on the kettle body 20 in a natural state without random deflection, semi-automatic control of the kettle cover 10 is realized, and the use convenience of a user is improved; in addition, the mounting seat 40 is detachably disposed on the top of the handle 30 (e.g., fixed on the top of the handle 30 by a fastener such as a screw), so that only the mounting seat 40 can be replaced when the mounting seat 40 is damaged without replacing the entire handle 30, and it is convenient to appropriately design the size and specific structure of the mounting seat 40 according to different kinds of liquid heating vessels.

Specifically, in a lid closing state, the elastic locking piece is in a natural state, that is, no elastic deformation occurs, when the lid is opened, the tail end of the kettle lid 10 (that is, the toggle part 11) is continuously toggled, and the toggle part 11 rotates around the rotating shaft 42 to drive the kettle lid 10 to be slowly opened; when the kettle lid 10 is opened, the elastic locking piece is elastically deformed to store elastic potential energy; when the kettle lid 10 is opened to a preset angle, the limiting piece 80 on the kettle lid 10 moves downwards and stops against the outer wall surface of the kettle body 20, as shown in fig. 2 and 4, so that the kettle lid 10 is prevented from being reversely rotated and covered under the driving of the elastic locking piece, a user can maintain the uncovering state of the kettle lid 10 without abutting against the toggle part 11, and the use comfort of the user is greatly improved; when the lid is closed, the lid closing key 70 is driven to release the stopping action of the limiting member 80 on the kettle body 20, and the elastic locking member releases the elastic potential energy to reset and drives the kettle lid 10 to rotate reversely until the open end of the accommodating cavity is closed, as shown in fig. 9 and 10. The rotating shaft 42 extends along the vertical direction, so that the kettle lid 10 rotates along the horizontal direction, and the lateral opening of the kettle lid 10 is realized; the limiting piece 80 is matched with the kettle body 20, so that the opening state of the kettle cover 10 can be maintained, and great convenience is brought to a user; meanwhile, the elastic locking piece enables the kettle lid 10 to be automatically closed without manually turning the kettle lid 10 back by a user, so that the automation degree of the liquid heating container is improved, and the use comfort of the user is further improved.

Such as: when a user takes the kettle to receive water from the water dispenser, the kettle cover 10 is opened towards the side, and the electric kettle with the lower kettle cover 10 can be installed in the water receiving area of the water dispenser to directly receive water, so that the water dispenser is very convenient; after receiving water, the cover closing key 70 is driven to close the cover.

It should be noted that the pot lid 10 in the present application may be a single-layer structure, or may be a multi-layer structure, such as an assembly including three-layer structures of an upper lid, an inner lid, and a lower lid.

Further, an installation space 15 and an avoiding hole 152 communicated with the installation space 15 and penetrating through the lower surface of the kettle lid 10 are arranged in the kettle lid 10, and the limiting member 80 comprises a limiting portion 81 limited in the installation space 15 and lower than the installation space 15 and a stopping portion 82 connected with the limiting portion 81 and longitudinally penetrating through the avoiding hole 152 to stop against the outer wall surface of the kettle body 20, as shown in fig. 3, 6, 8, 10, 12 and 15; the cover closing key 70 can drive the limiting part 81 to move upwards, so that the stopping part 82 retracts into the avoiding hole 152, as shown in fig. 7 and 8, to release the stopping of the kettle body 20.

The kettle cover 10 is internally provided with an installation space 15 and an avoidance hole 152, the limiting piece 80 comprises a limiting part 81 and a stopping part 82, the limiting part 81 is limited in the installation space 15, and the limiting piece 80 is ensured not to be separated from the kettle cover 10; the height of the limiting part 81 is lower than that of the mounting space 15, so that the limiting part 81 can move up and down in the mounting space 15, thereby ensuring that the limiting part 80 can move up and down relative to the kettle lid 10; the stopping part 82 penetrates through the avoiding hole 152, so that the lower end of the limiting part 80 can protrude out of the kettle lid 10, and further the stopping part stops against the kettle body 20 to play a limiting role.

The specific process is as follows: in the lid opening process, when the end of the stopping part 82 passes over the inner wall surface of the kettle body 20, the limiting part 80 moves downwards under the action of gravity, so that the lower end of the stopping part 82 protrudes out of the avoiding hole 152, at the moment, the shifting part 11 is released, and under the influence of the elastic locking part, the shifting part 11 has a tendency of reverse rotation, and the side surface of the stopping part 82 abuts against the outer wall surface of the kettle body 20 and cannot rotate continuously, as shown in fig. 3 and 6, so that an effective limiting effect is achieved on the kettle lid 10, the reverse buckling of the kettle lid 10 is avoided, and the kettle lid 10 can be automatically kept in a lid opening state, as shown in fig. 2 and 4; when the lid 10 is closed, the lid closing key 70 is triggered, so that the lid closing key 70 drives the limiting portion 81 to move upward, and the stopping portion 82 also moves upward and retracts into the avoiding hole 152, as shown in fig. 7 and 8, the stopping effect on the pot body 20 is released, and the lid 10 can rotate to cover the opening end of the accommodating cavity under the effect of the elastic locking piece.

Further, one end of the limiting portion 81 close to the cover closing key 70 is provided with a first guiding inclined surface 811, and the first guiding inclined surface 811 is inclined from top to bottom and is inclined in a direction away from the cover closing key 70, as shown in fig. 6 and 8; when the cover closing key 70 is driven, a pushing force can be applied to the first guide slope 811 to move the stopper 81 upward.

Spacing portion 81 is close to the one end that closes and covers key 70 and is equipped with first direction inclined plane 811, and first direction inclined plane 811 from top to bottom inclines, and to keeping away from the direction slope that closes and cover key 70, promptly: the upper end of the first guide slope 811 is closer to the cover closing key 70 than the lower end thereof, as shown in fig. 6 and 8. Thus, when the lid closing key 70 is driven, the pushing force applied to the first guiding inclined surface 811 can generate an upward component force, and since the stopping portion 82 located in the avoiding hole 152 limits the movement of the limiting member 80 in the horizontal direction, the limiting member 80 can only move upward in the vertical direction under the driving of the lid closing key 70, and further the stopping portion 82 retracts into the avoiding hole 152 to release the stopping of the kettle body 20, as shown in fig. 8. Therefore, the first guide inclined plane 811 can convert the horizontal movement of other structures (driving structures or transmission structures) into the vertical movement of the limiting part 81, and the structure is ingenious and simple.

Preferably, the lid 10 is further provided with a guide hole 141 communicating with the mounting space 15 and penetrating through the upper surface of the lid 10, and the lid closing key 70 is mounted in the guide hole 141, as shown in fig. 4 to 12, and can move up and down along the central axis of the guide hole 141; the liquid heating container further comprises a transmission member 90 which is limited in the installation space 15 and can slide in the installation space 15 in a reciprocating manner, one end of the transmission member 90 is abutted with the lower end of the cover closing key 70, and the other end of the transmission member 90 is abutted with the first guide inclined surface 811, as shown in fig. 5 to 10; when the lid-closing key 70 is pressed, the transmission member 90 is driven to slide toward the direction close to the limiting member 80, so that the transmission member 90 pushes the limiting member 80 to move upward, thereby releasing the stopping of the stopping portion 82 on the kettle body 20.

A second guiding inclined surface 71 is disposed at a lower end of the cover closing key 70 and/or at an end of the transmission member 90 close to the cover closing key 70, and the second guiding inclined surface 71 is inclined from top to bottom and is inclined in a direction away from the limiting member 80, as shown in fig. 6, 8 and 10.

The kettle lid 10 is also provided with a guide hole 141 in the vertical direction, the lid closing key 70 is installed in the guide hole 141, so that the lid closing key 70 can move up and down relative to the kettle lid 10, the lid closing key 70 can be driven by pressing the lid closing key 70, the use habit of a user is relatively met, and the operation and the use of the user are convenient; correspondingly, a transmission member 90 needs to be additionally arranged between the cover closing key 70 and the limiting portion 81, the transmission member 90 is driven to slide towards the direction close to the limiting member 80 by the downward movement of the cover closing key 70, and then the limiting portion 81 is driven to move upwards by the horizontal sliding of the transmission member 90.

Further, the lower end of the cover closing key 70 and/or the end of the transmission member 90 close to the cover closing key 70 are provided with a second guiding inclined plane 71, the second guiding inclined plane 71 is inclined from top to bottom and inclined to the direction far away from the limiting member 80, that is: the upper end of the second guiding inclined surface 71 is closer to the stopper 80 than the lower end, as shown in fig. 6, 8, 10 and 14. Thus, when the lid closing key 70 is pressed, a horizontal component force can be generated by the thrust applied to the second guiding inclined surface 71, and the gravity of the transmission member 90 and the installation space 15 limit the movement of the transmission member 90 in the vertical direction, so that the transmission member 90 can only move towards the direction close to the limiting member 80 along the horizontal direction under the driving of the lid closing key 70, further push the limiting portion 81 to move upwards, and drive the abutting portion 82 to retract into the avoiding hole 152 to release the abutting against the kettle body 20. Therefore, the second guiding inclined plane 71 can convert the vertical movement of the cover closing key 70 into the horizontal movement of the transmission member 90, and the cover closing key is ingenious in conception, simple in structure and convenient to replace and maintain.

Preferably, the lower end of the cover closing key 70 and the end of the transmission member 90 close to the cover closing key 70 are both provided with a second guiding inclined surface 71, as shown in fig. 6, 8, 10 and 14, which significantly increases the contact area between the cover closing key 70 and the transmission member 90, so that the movement of the cover closing key 70 and the transmission member 90 is more smooth. Of course, the driving member 90 may not be provided, and the cover closing key 70 directly drives the limiting member 80 to move upward, and at this time, the cover closing key 70 may be horizontally installed in the installation space 15, and when it horizontally slides in the installation space 15, the limiting member 80 may be pushed to move upward.

Preferably, one end of the transmission member 90 near the limiting portion 81 is provided with a third guiding inclined surface 91 parallel to the first guiding inclined surface 811, as shown in fig. 6, 8, 10 and 14.

One end of the transmission member 90 close to the limiting portion 81 is provided with a third guiding inclined surface 91, and the third guiding inclined surface 91 is parallel to the first guiding inclined surface 811, which also significantly increases the contact area between the transmission member 90 and the limiting portion 81, so that the movement of the transmission member 90 and the limiting member 80 is more stable.

Preferably, the upper surface of the pot lid 10 is provided with a guide post 14, and a guide hole 141 is provided in the guide post 14, as shown in fig. 5 to 10.

The upper surface of the pot lid 10 is provided with the guide post 14, and the guide hole 141 is arranged in the guide post 14, so that the length of the lid closing key 70 is increased, and further, the length of the lid closing key 70 limited in the pot lid 10 is increased, so as to avoid the situation that the lid closing key 70 is too short and easily falls off from the pot lid 10.

Preferably, the central axis of the guide hole 141 coincides with the central axis of the kettle body 20, as shown in figures 4 to 12.

The central axis of the guiding hole 141 is coincident with the central axis of the pot body 20, and the lid closing key 70 is positioned at the center of the pot lid 10, so that the beauty of the product is improved.

In any of the above embodiments, the liquid heating vessel further comprises: the elastic element is located in the installation space 15, the upper end of the elastic element abuts against the pot lid 10, and the lower end of the elastic element abuts against the limiting part 81, as shown in fig. 6, 8, 10, 14 and 15.

Wherein, the top of the position-limiting part 81 is provided with a groove 812, and the lower end of the elastic element is located in the groove 812, as shown in fig. 6, 8, 10 and 15.

The elastic piece is additionally arranged in the limiting space, the upper end of the elastic piece abuts against the kettle lid 10, the lower end of the elastic piece abuts against the limiting part 81, the upward movement of the limiting part 80 can be limited, and the stability of the limiting part 80 when abutting against the outer wall surface of the kettle body 20 is further improved. Specifically, in the natural state, the elastic member is in the natural state, so that the limiting member 80 is located at the lower position, as shown in fig. 10; in the process of opening the cover, when the limiting piece 80 moves upwards to cross the kettle body 20, the elastic piece is compressed, so that the elastic piece stores elastic potential energy; when the limiting member 80 passes the kettle body 20 and reaches the outside of the kettle body 20, the elastic member releases elastic potential energy, so that the limiting member 80 can rapidly move downwards to stop against the outer wall surface of the kettle body 20 and stably keep the limiting member at a lower position, as shown in fig. 4, thereby increasing the use reliability of the limiting member 80.

Preferably, the elastic member is a spring 83, and the spring 83 has good elasticity, easily available materials and low price. Of course, the elastic member is not limited to the spring 83, and may be in other forms such as a spring plate; or, the elastic member may not be provided, and the gravity of the limiting member 80 provides the power for the limiting member 80 to move downward, and at this time, the material of the limiting member 80 may be cast iron or other material with relatively high density.

The top of spacing portion 81 is equipped with recess 812, and the lower extreme of elastic component is located recess 812, and recess 812 has played better limiting displacement to the elastic component to avoid the elastic component to take place circumstances such as slope, aversion, skew, thereby improved the use reliability of elastic component.

In any of the above embodiments, one side of the stopping portion 82 is provided with a stopping surface for stopping the outer wall surface of the kettle body 20, and the other side of the stopping portion 82 is provided with a fourth guiding inclined surface (not shown in the figure), which is inclined from top to bottom and toward the direction close to the stopping surface, and has an upper end not lower than the opening end of the kettle body 20 and a lower end flush with the lower end of the stopping portion 82.

One side of the stopping part 82 is provided with a stopping surface which can be abutted against the outer wall surface of the kettle body 20 so as to realize the limiting function of the limiting part 80; the other side of the stopping part 82 is provided with a fourth guiding inclined plane, so that in the state of opening the lid, the stopping surface is abutted against the outer wall surface of the kettle body 20, and the fourth guiding inclined plane is deviated from the kettle body 20, therefore, in the process of opening the lid, the fourth guiding inclined plane is firstly contacted with the inner wall surface of the kettle body 20, and when the stopping part 82 passes through the kettle body 20 and reaches the outer side of the kettle body 20, the stopping part 82 moves downwards to enable the stopping surface to be abutted against the outer wall surface of the kettle body 20. Thus, in the process of opening the kettle lid 10, since the fourth guiding inclined plane is inclined from top to bottom and is inclined towards the direction close to the abutting surface (i.e. inclined towards the direction far away from the inner wall surface of the kettle body 20), and the upper end of the fourth guiding inclined plane is not lower than the opening end of the kettle body 20, the fourth guiding inclined plane can contact the opening end of the kettle body 20, and the opening end of the kettle body 20 applies an upward component force to the fourth guiding inclined plane, so that the limiting member 80 moves upward; and the lower end of the fourth guiding inclined plane is flush with the lower end of the stopping part 82, so that the end part of the stopping part 82 can cross the opening end of the kettle body 20 to reach the outer side of the kettle body 20.

Therefore, the fourth guiding inclined plane is arranged on the stopping part 82, so that the limiting part 80 can automatically move upwards to cross over the kettle body 20 in the uncovering process, the user does not need to manually drive the cover closing key 70 to avoid the interference between the stopping part 82 and the kettle body 20, the user can open the cover by only driving the toggle part 11, and the use comfort of the user is further improved.

In any of the above embodiments, one end of the mounting space 15 extends transversely and penetrates the side wall surface of the kettle lid 10 to form a mounting opening 151, as shown in fig. 6, 8, 10 and 16, and the limiting member 80 is mounted in the mounting space 15 through the mounting opening 151.

Preferably, the mounting space 15 extends transversely in a direction perpendicular to the vertical plane in the kettle body 20, and the retaining member 80 is located at the mounting opening 151, as shown in FIGS. 6, 8 and 10.

One end of the mounting space 15 extends transversely and penetrates through the side wall surface of the kettle lid 10 to form a mounting opening 151, so that the limiting member 80 (and the transmission member 90) can be installed in or separated from the mounting space 15 from the mounting opening 151, and assembly, overhaul and replacement are facilitated; compared with the mounting opening 151 formed in the surface of the kettle cover 10, the appearance of the kettle cover is improved, and the probability that sundries fall into the kettle body 20 or are accumulated on the kettle cover 10 through the mounting opening 151 is reduced, so that the cleanliness of the product is improved.

The mounting space 15 extends transversely along a direction perpendicular to a vertical plane (i.e. a plane passing through the central axis of the kettle body 20 and the rotation axis 42 of the kettle lid 10) in the kettle body 20, and the mounting opening 151 is located in the middle area of the handle 30 and the spout 21, so that the distance between the limiting piece 80 and the handle 30 and the spout 21 is basically equivalent, thereby avoiding inconvenience caused by over-small opening amplitude of the kettle lid 10 due to the fact that the limiting piece 80 is close to the spout 21, and avoiding increasing difficulty in opening the lid or causing torsional failure of the elastic locking piece due to over-large opening amplitude of the kettle lid 10 caused by over-close distance of the limiting piece 80 to the handle 30; meanwhile, the rotation direction of the limiting piece 80 in the reverse rotation is just perpendicular to the outer wall surface of the kettle body 20, so that the stopping effect of the kettle body 20 on the limiting piece 80 is improved, and the stability of the kettle lid 10 in the uncapping state is further improved.

The limiting member 80 is installed at the installation opening 151, namely, located at the edge area of the pot lid 10, so that the pot lid 10 can be rotated out of the pot body 20 as much as possible in the uncapped state compared with installing the limiting member at the middle area of the installation space 15, thereby facilitating the more thorough opening of the pot lid 10.

In any of the above embodiments, the elastic locking member is a torsion spring 50, and the torsion spring 50 is sleeved on the rotating shaft 42, as shown in fig. 11, 13, 14 and 16, the torsion spring 50 includes a fixed arm 51 and a movable arm 52, the fixed arm 51 is limited on the mounting seat 40, and the movable arm 52 is limited on the toggle portion 11.

The elastic locking piece is a torsion spring 50, the torsion spring 50 has good elasticity and large torsion force, and can apply relatively large cover closing acting force to the kettle cover 10, so that the kettle cover 10 can be tightly covered on the kettle body 20 when not subjected to external force, and the use reliability of the elastic locking piece is improved; meanwhile, the torsion spring 50 is convenient to machine and form, can be processed into various required shapes according to requirements, is easy to obtain materials, and is beneficial to saving cost.

The torsion spring 50 is sleeved on the rotating shaft 42, so that the main body part of the torsion spring 50 is effectively limited, the position of the torsion spring 50 is not changed in the processes of opening and closing the cover, and the use reliability of the torsion spring 50 is further ensured; and the torsion spring 50 and the kettle cover 10 share one rotating shaft 42, so that the cover opening structure of the liquid heating container is simplified. Of course, the torsion spring 50 and the lid 10 may not share one rotating shaft 42, but may be separately provided.

The movable arm 52 of the torsion spring 50 is limited on the toggle part 11, the fixed arm 51 is limited on the mounting seat 40, in the process of opening and closing the lid, the toggle part 11 rotates relative to the mounting seat 40, so that the movable arm 52 of the torsion spring 50 also changes position relative to the fixed arm 51, and generates elastic deformation, thereby ensuring that the kettle lid 10 rotates to open and rotate to close, the torsion spring 50 keeps synchronous deformation, and further ensuring the use reliability of the torsion spring 50.

Of course, the elastic locking member is not limited to the torsion spring 50, and may be other elastic members, such as a compression spring, an extension spring, a spring plate, etc., which are not illustrated, so long as the lid 10 can be stably covered on the pot body 20 without external force, and the object of the present invention can be achieved without departing from the design concept and spirit of the present invention, and therefore, those skilled in the art should understand that these embodiments are all within the protection scope of the present invention.

The fixed arm 51 is inserted into the insertion hole 44 or the insertion slot on the mounting seat 40, so that the situation that the fixed arm 51 is displaced or shaken and even separated from the mounting seat 40 is effectively avoided, and the elastic deformation of the torsion spring 50 is completely determined by the movement amplitude of the movable arm 52; and the movable arm 52 is inserted in the limiting hole 13 or the limiting groove on the stirring part 11, so that the movable arm can keep synchronous motion with the tail end of the pot lid 10 (namely, the stirring part 11) without separating from the stirring part 11, thereby accurately reflecting the motion situation of the tail end of the pot lid 10, further ensuring that the elastic deformation of the torsion spring 50 accurately corresponds to the opening and closing state of the pot lid 10, effectively ensuring the use reliability of the torsion spring 50, and ensuring that the pot lid 10 can be automatically reset when opened bidirectionally.

Alternatively, the stationary arm 51 and the movable arm 52 each extend in a vertical direction, as shown in fig. 13, 15, and 16.

The fixed arm 51 and the movable arm 52 both extend along the vertical direction, and the toggle part 11 and the mounting seat 40 are respectively provided with the limiting hole 13 and the jack 44 along the vertical direction, so that the movable arm 52 and the fixed arm 51 can be effectively limited, and the deformation of the torsion spring 50 is ensured to accurately correspond to the opening and closing state of the kettle lid 10; in addition, the movable arm 52 can be inserted into a deeper position of the toggle part 11, so as to more easily drive the lid 10 to reset.

Alternatively, both the fixed arm 51 and the movable arm 52 extend in the horizontal direction.
