The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

In the electric kettle with a separable kettle lid in the existing design, referring to fig. 5 and 6, an upper kettle lid 6 and a lower kettle lid 7 are buckled to form a kettle lid cavity 2, two locking pieces 8 are radially and symmetrically arranged in the kettle lid cavity 2, and the locking pieces 8 can be axially and fixedly limited (i.e. the locking pieces 8 can only move along the radial direction) by the upper kettle lid 6 and the lower kettle lid 7. In addition, still be provided with compression spring between two hasp pieces 8, like this, when the user opened the pot lid, the radial inner tip 81 that presses two hasp pieces 8 radially inwards simultaneously can make hasp piece 8 radially retrieve, then withdraws and exert the effort that exerts in this radial inner tip 81 and just can make hasp piece 8 restore to the throne under compression spring's effect and stretch out.

However, for a high-height lid (e.g. a lid with a handle 1), the radially inner end 81 of the locking member 8 needs to extend upward into the handle cavity to adapt to the height of the lid, i.e. to increase the axial height of the lid. From this, through the top of end 81 in the radial of pressing latch part 8 in order to open or when closing the pot lid, appear easily in latch part 8 for example its radial outer tip 82 uses the bottom of its radial inner tip 81 as the fulcrum and the situation that upwarps, thereby make the radial outer tip 82 and the radial inner tip 81 of latch part 8 respectively with last pot lid 6 and pot lid 7 looks butt down, the coefficient of friction of latch part 8 at the radial in-process that slides has been increased, not only increased the effort that the user applyed in latch part 8 when uncapping like this, but also can not smoothly slide latch part 8, there is stronger retardant sense, seriously influence user's operation impression.

In view of the above, according to one aspect of the present invention, there is provided a novel pot lid, referring to fig. 1 and fig. 2, the pot lid includes a top handle 1, wherein the pot lid further includes a latch assembly disposed in a pot lid cavity 2 and a lever hinge mechanism, a top lever end of the lever hinge mechanism is a pressing operation end for manual operation by a user and extends upwards into the handle 1 cavity, and a bottom lever end of the lever hinge mechanism is hinged to drive the latch assembly to extend or retract in a radial direction.

According to another aspect of the present invention, there is provided an electric kettle, wherein the electric kettle comprises the above-mentioned kettle lid, and the kettle lid is detachably buckled on the kettle mouth of the electric kettle through a locking assembly. Specifically, the electric kettle comprises an inner container capable of containing and heating liquid, and the kettle opening is the top end opening of the inner container.

In the invention, a lifting handle 1 is arranged at the top of the kettle cover, a lock catch component and a particularly additionally arranged lever hinge mechanism are arranged in a kettle cover cavity 2, and particularly, the lever bottom end of the lever hinge mechanism is hinged with the lock catch component. Therefore, when a user opens or closes the kettle cover, the locking assembly can be more smoothly driven to be recovered along the radial direction only by pressing the top end of the lever, and then the locking assembly can be driven to reset and extend along the radial direction by removing the acting force applied to the top end of the lever, so that the locking assembly is not easy to tilt.

To pot lid height higher, for example, be provided with the pot lid of handle 1, so set up, can reduce the coefficient of friction of hasp subassembly at the radial in-process that slides effectively to make the user laborsaving and smoothly open or close this pot lid, can greatly improve user's use and experience.

The lever hinge mechanism is provided with a lever fulcrum, and the lever hinge mechanism can rotate around the lever fulcrum by pressing the top end of the lever positioned in the handle cavity (at the moment, the bottom end of the lever also rotates around the lever fulcrum), so that the lock catch assembly connected with the bottom end of the lever is driven to move radially, and the operation of a user is facilitated. In addition, the bottom end of the lever is hinged with the locking assembly, referring to fig. 3, the movable connection mode can ensure that the locking assembly smoothly slides along the radial direction under the hinged driving of the bottom end of the lever, and the tilting or the jacking of the upper pot cover and the lower pot cover is not easy to generate, thereby ensuring that a user can open and close the pot cover easily and smoothly in a labor-saving way.

In particular, the catch assembly may be a single catch member disposed within the lid cavity 2, but is preferably a set of symmetrically disposed catch members that are capable of synchronous smooth extension or retraction in a radial direction upon actuation of the lever hinge mechanism. In addition, the lever hinge mechanism may have a plurality of suitable arrangements, for example, the lever hinge mechanism is a cross lever structure (corresponding to the case of arranging 2 locking components) or a single lever structure (corresponding to the case of arranging a single locking component), and may also be in other arrangements, which will not be described in detail herein.

For smooth operation, the lever hinge mechanism is preferably a cross-lever structure, and the latch assembly employs 2 radially symmetric latch members. Specifically, referring to fig. 1 to 3, the lever hinge mechanism includes a first lever 31 and a second lever 32 which are disposed crosswise and pivot about a rotation shaft 33 penetrating through the crossing portion, a latch assembly includes a first latch 41 connected to a lever bottom end of the first lever 31 and a second latch 42 connected to a lever bottom end of the second lever 32, the first latch 41 and the second latch 42 are arranged to be extended and contracted in a radial direction, a first key 51 and a second key 52 arranged at both ends in the radial direction are further embedded in an outer peripheral portion of the handle 1, and the first key 51 and the second key 52 can press and drive lever top ends of the first lever 31 and the second lever 32 toward each other.
