The invention provides a liquid heating container, which can be a container which can be used for heating liquid, such as an electric kettle or a health preserving kettle and the like.

In the embodiment of the present invention, as shown in fig. 1, the liquid heating container includes a body 10 and a lid 20, the lid 20 is disposed to cover the body 10, specifically, the lid 20 is pivotally connected to the body 10, that is, the lid 20 can be rotated to open relative to the body 10. An elastic restoring element is arranged between the pot lid 20 and the pot body 10, so that the pot lid 20 has a tendency to open relative to the pot body 10. Optionally, an elastic restoring member is disposed at the pivot joint of the lid 20 and the kettle body 10, for example, the elastic restoring member is a torsion spring. Of course, the elastic reset piece can also be arranged on the side wall of the kettle body and the bottom wall of the kettle cover. In addition, the elastic reset piece can also be a spring. A spout is further provided on the pot body 10 to pour out water when the pot lid 20 is closed.

Referring to fig. 2 to 7, further, the liquid heating container further includes a lock 30 and an elastic component 40, and a fastening member is disposed on the inner peripheral wall of the kettle body 10 and at a position close to the kettle opening; the lock catch 30 is movably arranged on the kettle cover 20 and has a locking state buckled with the buckling piece and an unlocking state separated from the buckling piece, and by applying pressure to the kettle cover 20, the lock catch 30 can move circumferentially and axially to realize switching between the locking state and the unlocking state; in the locked state, the lid 20 covers the body 10, and in the unlocked state, the lid 20 is opened relative to the body 10. The elastic member 40 is connected to the locking buckle 30 and the lid 20, respectively, and gives the locking buckle 30a tendency to move in a circumferential direction and in an axial direction.

In this embodiment, when the pot lid 20 is pressed, the locking catch 30 can move downward along with the pot lid 20, and the elastic member 40 can be compressed or stretched by the contact with the locking member, so that the locking catch 30 has a tendency to move in the circumferential direction and in the axial direction. When the pressure on the lid 20 is removed, the elastic member 40 is deformed to push the locking member 30 to move in the circumferential direction and the axial direction, so that the locking member 30 is locked to or unlocked from the locking member. It should be noted that. The locking catch 30 in the embodiment of the present invention is capable of axial movement and circumferential movement, wherein axial direction refers to the axial direction of the locking catch itself, i.e. the length direction of the locking catch, and circumferential direction refers to the circumferential direction of the locking catch 30 itself, i.e. the direction corresponding to the locking catch 30 itself being capable of rotational movement, and the circumferential direction is the direction extending along the circumferential direction of the lid 20.

Alternatively, the fastener is a fastening hole 13a, and the lock catch 30 is inserted into the fastening hole 13a in the locked state. Of course, in other embodiments, the fastener may be a bump, and the lock catch 30 abuts against the lower surface of the fastener in the locked state.

In this embodiment, the lock catch 30 has a first end 30a and a second end 30b opposite to each other, and the lock hole 13a has two opposite side edges extending in the up-down direction; the first end 30a can move up and down along the inner peripheral wall of the kettle body 10, and the first end 30a can extend into or out of the fastening hole 13a, and optionally, the first end 30a can slide out of the fastening hole 13a downwards along the lower wall of the fastening hole 13 a. In order to slide the first end 30a out of the fastening hole 13a, at least one of the lower surface of the first end 30a and the lower wall of the fastening hole 13a is an inclined wall 13b, and the inclined wall 13b is inclined downward in a direction toward the elastic member 40. Alternatively, the first end 30a may exit the fastener hole 13a in the axial direction of the fastener 30 itself. In order to allow the first end 30a to move up and down along the inner peripheral wall of the can 10, at least one of the surfaces of the first end 30a and the inner peripheral wall of the can 10 contacting each other is an inclined wall to avoid interference between the two. The elastic member 40 has one end connected to the second end 30b and the other end connected to the lid 20.

In the lid-opened state, by applying pressure to the lid 20, the first end 30a moves downward while the latch (30) moves circumferentially to displace the second end 30b in the horizontal direction to compress the elastic member 40, for example, the latch 30 can rotate in the horizontal direction to swing the second end 30b in the horizontal direction; when the pressure on the pot lid 20 disappears, the elastic component 40 pushes the second end 30b to make the first end 30a snap into the buckling hole 13a, and the elastic component 40 makes the first end 30a have a tendency to move towards one side edge, so that the pot lid 20 is covered with the pot body 10;

when the kettle cover 20 is closed, the lock catch 30 moves axially in the direction away from the buckle hole 13a by applying pressure to the kettle cover 20, and when the first end slides out of the buckle hole 13a, the lock catch 30 moves circumferentially under the action of the elastic component 40 and moves towards the side edge; when the pressure applied to the lid 20 is released, the lid 20 is opened relative to the kettle body 10, and the first end 30a moves upward along with the lid 20.

In this embodiment, when the latch 30 is engaged with the fastening hole 13a, the elastic component 40 makes the first end 30a have a tendency of moving toward the lateral edge of the fastening hole 13a, so that when the latch 30 is disengaged from the fastening hole 13a, the first end 30a moves toward the lateral edge of the fastening hole 13a under the action of the elastic component 40 and is dislocated from the fastening hole 13a in the vertical direction, and thus when the first end 30a moves upward, the first end 30a can be prevented from being clamped into the fastening hole 13a, which may cause the lid 20 to be opened unsuccessfully.

In the present invention, when the pot body 10 is in the open state, the pot lid 20 is rotated downward by applying a pressure to the pot lid 20, and the locking buckle 30 moves downward along with the pot lid 20, so that the elastic member 40 is compressed. When the pressure on the lid 20 is removed, the elastic member 40 pushes the second end 30b of the latch 30 to make the first end 30a of the latch 30 snap into the latching hole 13a, so as to cover the lid 20 and the pot body 10, wherein the pot body 10 is in a covered state, and in the covered state, the elastic member 40 makes the first end 30a of the latch 30 have a tendency to move towards the side edge of the latching hole 13 a. When the kettle lid 20 needs to be opened again, the kettle lid 20 is pressed downwards again, because the second end 30b of the lock catch 30 is connected with the kettle lid 20 through the elastic component 40, that is, the lock catch 30 can move back and forth relative to the fastening hole 13a, then the first end 30a of the lock catch 30 can slide out of the fastening hole 13a along the lower hole wall of the fastening hole 13a, because the first end 30a is no longer abutted to the hole wall of the fastening hole 13a, that is, the first end 30a is not limited by the hole wall of the fastening hole 13a, the first end 30a can move towards the side edge of the fastening hole 13a under the action of the elastic component 40, that is, the first end 30a is arranged deviating from the fastening hole 13a in the up-down direction. When the force acting on the lid 20 disappears, the lid 20 bounces upward under the force of the torsion spring, and the first end 30a of the latch 30 moves upward along the inner peripheral wall of the pot body 10. By adopting the mode to open or close the kettle lid 20, only pressure needs to be directly applied to the kettle lid 20, and the additional arrangement of the press button on the kettle lid 20 or the kettle body 10 is not needed to transfer the pressure, so that the arrangement of the press button on the liquid heating container can be avoided, and the smooth opening of the kettle lid 20 can be ensured.

In this embodiment, a fastening protrusion 13 is disposed on the inner peripheral wall of the kettle body 10 and near the kettle opening, and a fastening hole 13a is disposed on the fastening protrusion 13. By providing the fastening protrusion 13 on the inner peripheral wall of the can 10 and forming the fastening hole 13a on the fastening protrusion 13, the phenomenon of water leakage from the inner peripheral wall of the can 10 at the position of the fastening hole 13a due to the fastening hole 13a being directly formed on the inner peripheral wall of the can 10 can be avoided. In other embodiments, the fastening hole 13a may be formed on the inner peripheral wall of the kettle body 10.

The buckling convex part 13 is provided with a first surface 13d and a second surface 13g which are oppositely arranged and extend along the vertical direction, the buckling hole 13a is arranged through the first surface 13d, and a notch 13c is formed on the first surface 13 d; in the direction in which the second surface 13g points to the first surface 13d, the upper surface of the buckling protrusion 13 is gradually inclined downward, and when the pot lid 20 is pressed downward, the first end 30a slides downward along the upper surface of the buckling protrusion 13; when the pressure on the lid 20 is removed, the first end 30a is inserted into the hole 13a from the notch 13 c. For better explanation, in the present embodiment, a direction in which the first surface 13d is directed toward the second surface 13g is taken as a first direction, and a dotted arrow a shown in fig. 4 to 6 indicates the first direction. In this embodiment, the upper surface of the fastening protrusion 13 forms a guiding surface 13h, which guides the movement of the first end 30a and guides the first end 30a to gradually move downward and toward the notch 13c of the fastening hole 13 a. When the first end 30a moves to a position close to the notch 13c, the elastic element 40 may be in a compressed state, and the elastic element 40 springs the second end 30b of the lock catch 30 toward the opening of the notch 13c, so that the first end 30a of the lock catch 30 moves toward the opposite direction of the opening of the notch 13c and is clamped into the lock hole 13a from the notch 13 c. Or in other embodiments, after the first end 30a moves to a position close to the notch 13c, the elastic element 40 may be in a stretched state, and the elastic element 40 pulls the second end 30b of the lock catch 30 along the opening direction of the notch 13c, so that the first end 30a of the lock catch 30 moves towards the opposite direction of the opening direction of the notch 13c and is snapped into the lock hole 13a from the notch 13 c.

Optionally, the first end 30a has a third surface 30c matching with the upper surface of the buckling protrusion 13, and the third surface 30c and the upper surface of the buckling protrusion 13 are configured in a shape-following manner, which is equivalent to that the first end 30a contacts with the upper surface of the buckling protrusion 13 through an inclined surface, which is beneficial to the smooth sliding of the first end 30 a. In this embodiment, the third surface 30c and the upper surface of the buckling protrusion 13 are disposed in a profile, which means that the third surface 30c is gradually inclined downward in a direction in which the second surface 13g is directed to the first surface 13d, i.e. the third surface 30c and the upper surface of the buckling protrusion 13 are inclined in the same direction.

The first surface 13d includes a first sub-surface 13e and a second sub-surface 13f arranged along the up-down direction, the first sub-surface 13e connects the upper surface of the locking protrusion 13 and the hole wall of the fastening hole 13a, respectively, the second sub-surface 13f connects the lower surface of the locking protrusion 13 and the hole wall of the fastening hole 13a, respectively, and the first sub-surface 13e is arranged to protrude the second sub-surface 13f away from the second surface 13 g. In this embodiment, the first sub-surface 13e is disposed to protrude from the second sub-surface 13f, i.e. the upper hole edge corresponding to the fastening hole 13a is disposed to protrude from the lower hole edge. Specifically, when the kettle lid 20 is pressed down, the first end 30a of the lock catch 30 moves downward along the upper surface of the fastening protrusion 13, and when the first end 30a moves to abut against the second sub-surface 13f, the pressure acting on the kettle lid 20 is removed, at this time, the kettle lid 20 rotates upward under the action of the torsion spring, and when the kettle lid 20 rotates upward until the lock catch 30 is located at the notch 13c of the fastening hole 13a, since the upper hole edge of the fastening hole 13a protrudes out of the lower hole edge, the upper hole edge of the fastening hole 13a can limit the lock catch 30, so as to prevent the lock catch 30 from moving upward, that is, the kettle lid 20 can be limited from rotating upward, and meanwhile, under the action of the elastic component 40, the first end 30a of the lock catch 30 moves toward the fastening hole 13a, so that the first end 30a is clamped into the fastening hole 13 a. Therefore, the first sub-surface 13e is protruded from the second sub-surface 13f, so that the first end 30a of the latch 30 can be better ensured to be clamped into the latch hole 13a, and the first end 30a of the latch 30 directly strides over the notch 13c and moves towards the first sub-surface 13e after the pressure is removed.

When the lid needs to be closed, if the pressure acting on the lid 20 is slightly greater, and the first end 30a of the lock catch 30 moves downward to exceed the lock hole 13a, if the height of the first sub-surface 13e protruding from the second sub-surface 13f is not significant, the blocking effect of the first sub-surface 13e on the first end 30a of the lock catch 30 is poor, and after the pressure acting on the lid 20 disappears, the first end 30a of the lock catch 30 easily moves upward along the path 1 to return to the upper surface of the lock catch protrusion 13, and cannot be locked into the lock hole 13 a. Therefore, in the present embodiment, the horizontal distance B between the first sub-surface 13e and the second sub-surface 13f is greater than or equal to 0.5mm, which can avoid the above phenomenon. Alternatively, the horizontal distance B between the first sub-surface 13e and the second sub-surface 13f is 0.5mm, 1mm, 3mm, etc., so that the locking catch 30 is prevented from returning directly along the force 1 without being caught in the locking hole 13a when the pressing force is slightly larger than downward beyond the locking hole 13a and when the pressure applied to the lid 20 is removed.

Optionally, the lower surface of the first end 30a and the lower hole wall of the fastening hole 13a are both inclined walls 13b, which is equivalent to that the first end 30a contacts the lower hole wall of the fastening hole 13a through an inclined surface, so that the first end 30a can move more smoothly when sliding out of the fastening hole 13 a.

In this embodiment, the elastic assembly 40 includes a first spring 41, one end of the first spring 41 is connected to the second end 30b, the other end of the first spring 41 extends away from the fastening hole 13a and is fixed to the lid 20, and the first spring 41 at least tends to move axially with respect to the fastening device 30. The resilient assembly 40 further comprises a second spring 42, the second spring 42 connects the second end 30b and the lid 20, respectively, and the second spring 42 at least tends to move the lock catch 30 in a circumferential direction. And the second spring 42 and the first spring 41 are arranged at an included angle, and the included angle is larger than 0 degree and smaller than 180 degrees. Alternatively, the angle between the second spring 42 and the first spring 41 is 90 °, however, the angle between the second spring 42 and the first spring 41 may also be 20 °, 60 °, 150 °, or the like. In other embodiments, only the first spring 41 may be provided, the first spring 41 causing the shackle 30 to have both a tendency to move axially and a tendency to move circumferentially.

In this embodiment, the second spring 42 is a compression spring and is located on the side where the second surface 13g is located. Of course, in other embodiments, the second spring 42 is an extension spring and is located on the side of the first surface 13 d.

Specifically, in the embodiment where the second spring 42 is located on the side of the second surface 13g, when the kettle lid 20 is pressed downward, the first end 30a slides downward along the upper surface of the fastening protrusion 13 to the notch 13c of the fastening hole 13a, the second end 30b swings toward the direction of the second spring 42 to compress the second spring 42, and the first spring 41 is biased away from the opening direction of the fastening hole 13a and is stretched toward the direction of the second spring 42; when the pressure on the lid 20 is removed, the second spring 42 pushes the second end 30b to move in the direction opposite to the first direction, and the first end 30a is inserted into the locking hole 13a from the notch 13c of the locking hole 13a, and the second spring 42 is in a compressed state, so that the second end 30b has a tendency to move in the direction from the second surface 13g to the first surface 13d, and correspondingly the first end 30a has a tendency to move in the direction from the first surface 13d to the second surface 13g, i.e. the first end 30a has a tendency to move towards the side edge of the locking hole 13 a.
