The invention provides a kettle cover and an electric kettle with the kettle cover.

Referring to fig. 1, in an embodiment of the present invention, the electric kettle includes a kettle body and a kettle lid for covering the kettle body, the kettle lid includes:

the kettle cover body is provided with a steam opening 101;

a baffle 20 movably connected to the pot lid body and having a covering position for covering the steam opening 101 and an opening position for opening the steam opening 101;

the temperature sensing limiting structure 40 comprises a limiting structure used for limiting the baffle plate 20 at an opening position and a temperature sensing element 43 used for releasing the limiting function of the limiting structure when the temperature of the steam in the electric kettle reaches a preset temperature; and

the reset structure 30 is connected with the kettle lid body and the baffle 20 and used for resetting the baffle 20 for releasing the limit to the covering position.

In the present embodiment, specifically, the baffle 20 is horizontally movably connected to the pot lid body to movably cover the steam opening 101 and movably open the steam opening 101. However, the design is not limited thereto, and in other embodiments, the baffle 20 may also be, but is not limited to, pivoted on the lid body, so that the baffle 20 can open the steam opening 101 and close the steam opening 101 around the pivoted position relative to the lid body.

Referring to fig. 4, 6 and 8 together, further, the limiting structure includes a locking member 41 connected to the baffle 20, and a limiting member 42 disposed on the lid body at a position far from the steam opening 101, and the baffle 20 can be locked on the limiting member 42 by the locking member 41 to be limited at the open position. The temperature sensing element 43 is used for driving the locking element 41 to disengage from the limiting element 42 when the temperature of the steam in the electric kettle reaches a preset temperature, so as to release the limiting function of the limiting structure, and thus the baffle 20 is reset to the covering position under the resetting function of the resetting structure 30. However, the design is not limited thereto, and in other embodiments, the limiting structure may also be other structures capable of limiting, for example, but not limited to, a telescopic member disposed on the pot lid body at a position away from the steam opening 101, and a limiting groove disposed on the baffle 20, and the telescopic member may extend into the limiting groove to limit the baffle 20 at the open position.

Further, the reset structure 30 comprises an elastic reset element 31, one end of the elastic reset element 31 is connected with the pot lid body, and the other end of the elastic reset element 31 is connected with the baffle 20, so that the baffle 20 has a tendency of resetting to the covering position, and thus, once the limit function of the limit structure is released by the temperature sensing element 43, the baffle 20 can automatically reset to the covering position. However, the present design is not limited thereto, and in other embodiments, the reset structure 30 may also be, but is not limited to, a driving structure similar to a rack and pinion or a worm and gear, so as to drive the baffle 20 to reset to the covering position; it can be understood that, in the present embodiment, the elastic restoring member 31 is used for restoring, so that the structure is simpler and the consumption of driving energy can be avoided.

In the present embodiment, the elastic restoring member 31 is preferably a compression spring. In addition, in order to enhance the installation stability of the elastic reset piece 31, the pot lid body is provided with a spring positioning column 22 for sleeving one end of the compression spring, and the baffle plate 20 is provided with a spring positioning column 124 for sleeving the other end of the compression spring (see fig. 1). However, the design is not limited thereto, and in other embodiments, the elastic restoring member 31 may also be a rubber elastic belt, a rubber sleeve that is corrugated in the length direction, and the like, and the invention is not limited thereto.

In addition, this pot lid body still is equipped with the assembly space who supplies baffle 20, reset structure 30 and the installation of temperature sensing limit structure 40, so, on the one hand the pot lid body can provide the protection for baffle 20, reset structure 30 and temperature sensing limit structure 40, and on the other hand can avoid baffle 20, reset structure 30 and temperature sensing limit structure 40 to show at pot lid body surface, and makes the surface of pot lid body more clean and tidy, and the outward appearance is good.

In this embodiment, before the water in the electric kettle is heated to boiling, a user can open the baffle 20 to the open position, and the locking member 41 is buckled with the limiting member 42, so as to limit the baffle 20 to the open position (as shown in fig. 4), so that the steam opening 101 on the kettle cover body is opened, a large amount of steam generated after the water is boiled can escape from the steam opening 101 to an external space, and the temperature controller of the electric kettle cannot jump off, so that the boiling time of the water in the electric kettle is prolonged, and healthier hot water is obtained; in addition, in the process that the steam escapes from the steam opening 101 to the external space, part of the steam continuously acts on the temperature sensing element 43 in the rising process, so that the temperature sensing element 43 absorbs the heat carried by the part of the steam to raise the temperature, when the temperature of the temperature sensing element 43 is raised to a preset temperature, the temperature sensing element 43 drives the locking element 41 to be disengaged from the limiting element 42 (as shown in fig. 6), so that the baffle 20 is reset to the covering position (as shown in fig. 8) under the resetting action of the elastic resetting element 31, and thus, the steam opening 101 is covered by the baffle 20, so that the steam cannot escape to the external space, and further, the temperature controller of the electric kettle is tripped.

In the technical scheme of the invention, on one hand, whether the baffle 20 is opened to the opening position can be operated by a user according to the requirement, so that whether the boiling time of water is prolonged can be selected; on the other hand, due to the fact that the temperature sensing limiting structure 40 and the reset structure 30 are additionally arranged, the baffle 20 can be automatically reset to the covering position after the boiling time of water is prolonged, the electric kettle can automatically return to a normal tripping state, the phenomenon that the electric kettle is not tripped after being burnt to dry is avoided, and the reliability of water boiling tripping of the electric kettle is improved.

Referring to fig. 1, 4, 6 and 8, in the present embodiment, further, the restoring structure 30 further includes a damper 32 disposed between the baffle plate 20 and the pot lid body. The damping direction of the damper 32 is parallel to the direction from the steam opening 101 toward the stopper 42. And, one end of the damper 32 is connected to the baffle 20, and the other end is connected to the pot lid body, of course, the damping force applied by the damper 32 to the baffle 20 is smaller than the compression force applied by the elastic restoring member 31 to the baffle 20, so as to slow down the speed of the baffle 20 returning from the open position to the lid closing position. It will be appreciated that the addition of the damper 32 facilitates further lengthening of the boiling time of the water.

In this embodiment, in order to control the delay time of water boiling, the damper 32 preferably uses a damper 32 whose damping coefficient is adjustable. Thus, the delay time of water boiling can be adjusted by adjusting the damping coefficient of the damper 32; the delay time of water boiling can be controlled to be 3-5 minutes without loss of generality; in addition, the damper 32 with adjustable damping coefficient is selected, so that manufacturers can conveniently manufacture electric kettles with different water boiling delay times by adjusting the damping coefficient, different requirements of users are met, and manufacturing flexibility is improved.

In addition, in this embodiment, the damper 32 can be detachably connected to the baffle 20 and the kettle lid body, so that the damper 32 with a proper damping coefficient can be replaced by a user according to the delay time of water boiling. In this embodiment, specifically, the damper 32 is preferably a rod-type damper, and includes a damping housing 321, and an expansion rod 322 (see fig. 1) that can be moved in and out of the damping housing 321. A limit cavity matched with the damping shell 321 in shape and size is limited in the kettle cover body, the damping shell 321 is accommodated in the limit cavity, and the limit cavity can limit all degrees of freedom of the damping shell 321 except the rotation of the central shaft, namely, the damping shell 321 can rotate along the central shaft in the limit cavity but cannot generate any position deviation relative to the kettle cover body; the free end of the telescopic rod 322 can extend out of the limiting cavity and is fixedly connected with the baffle 20, and the free end of the telescopic rod 322 is preferably fixedly connected with the end of the baffle 20 far away from the steam opening 101, and of course, the fixation between the two is detachable. It should be noted that, in other embodiments, the damper 32 may also be, but is not limited to, a rotary damper 32.

Referring to fig. 1, in the present embodiment, preferably, the pot lid body includes a top lid 11 and a first inner lid 12 disposed below the top lid 11. In addition, in the present embodiment, the steam opening 101 includes a first steam sub-opening 111 provided in the top cover 11, and a second steam sub-opening 121 provided in the first inner cover 12. Generally, the second steam sub-port 121 is disposed opposite the first steam sub-port 111 to facilitate escape of steam. In addition, in order to prevent particle pollutants such as dust from entering the electric kettle from the steam opening 101, the first steam sub-opening 111 and the second steam sub-opening 121 are preferably arranged in a grid shape. In particular, a plurality of grid segments 121a are spaced in the second steam sub-port 121, and any grid segment 121a is disposed obliquely upward in a direction away from the restoring structure 30, so as to guide the steam in a direction away from the restoring structure 30, thereby delaying the rate of high-temperature aging of the restoring structure 30.

It should be noted that, in this embodiment, the pot lid body may further include a second inner lid 13 disposed below the first inner lid 12, and similarly, the steam opening 101 further includes a third steam sub-opening 131 disposed opposite to the second steam sub-opening 121. In this embodiment, a limiting cavity for the damping housing 321 to be accommodated is formed between the first inner cover 12 and the second inner cover 13, specifically, a first limiting sub-cavity 133 (see fig. 1) with an upward opening is formed on the second inner cover 13, a second limiting sub-cavity with a downward opening is formed on the first inner cover 12, and the first limiting sub-cavity 133 and the second limiting sub-cavity are opposite to each other to form the limiting cavity together.

Referring to fig. 4, in this embodiment, in order to facilitate the user to open the baffle 20 to the open position, the baffle 20 is preferably further provided with a toggle member 21, the top cover 11 is provided with a sliding slot 112 through which the toggle member 21 movably extends, the sliding slot 112 extends along a direction from the steam opening 101 to the limiting member 42, and the toggle member 21 can move along the sliding slot 112 to drive the baffle 20 to open or close the steam opening 101. Without loss of generality, the baffle 20 and the toggle member 21 may be injection-molded integrally, so as to facilitate mass production.

Referring to fig. 1, 4, 6 and 8, in the present embodiment, the locking member 41 further includes a supporting arm 411 extending from the baffle 20 to the limiting member 42, and a lock 412 disposed at a free end of the supporting arm 411. The lock 412 is used to lock with the position-limiting member 42. The temperature sensing element 43 is used to push the latch 412 according to the temperature in the electric kettle until the latch 412 is separated from the limiting element 42. In this embodiment, an end of the supporting arm 411 away from the latch 412 is preferably rotatably connected to the bezel 20, so that the temperature sensing element 43 can push the latch 412 away from the limiting element 42. However, the design is not limited thereto, and in other embodiments, an end of the supporting arm 411 away from the latch 412 may also be fixedly connected to the baffle 20, as long as the supporting arm 411 has elasticity.

Furthermore, the limiting member 42 is a limiting protrusion disposed on the lid body, and the lock catch 412 is used for engaging a side surface of the limiting protrusion away from the steam opening 101, so that the baffle 20 can be limited at the opening position by the cooperation of the lock catch 412 and the limiting protrusion. However, the design is not limited thereto, and in other embodiments, the limiting member 42 may also be a limiting recess disposed on the pot lid body. In addition, in the present embodiment, the limiting member 42 is disposed on the first inner lid 12 and protrudes toward the top lid 11.

In this embodiment, it is preferable that the limiting protrusion is disposed to be gradually convex in a direction away from the steam opening 101, so as to form a guiding slope on a side surface of the limiting protrusion close to the steam opening 101, so that the lock catch 412 can slide along the guiding slope to a position where the limiting protrusion is engaged with the baffle 20 during the process of moving the baffle to the open position. Similarly, in the present embodiment, the lock 412 is disposed in a gradually convex manner in a direction approaching the steam opening 101, so as to form a guiding slope on the side of the lock 41 facing away from the steam opening 101. However, the design is not limited thereto, and in other embodiments, a guiding slope may be alternatively disposed on the lock catch 412 and the limiting protrusion.

In this embodiment, a temperature sensing opening 102 is further disposed on a side of the lid body facing away from the steam opening 101 of the limiting member 42. The temperature sensing element 43 includes a temperature sensing deformation element 431 disposed at the temperature sensing opening 102, a first end of the temperature sensing deformation element 431 is connected to the lid body, and a second end of the temperature sensing deformation element 431 is configured to bend toward the temperature sensing opening 102 according to the temperature in the electric kettle, so that the second end pushes the lock catch 412 to disengage from the limiting element 42. It can be understood that the temperature sensing port 102 is communicated with the inner cavity of the electric kettle, so that the temperature sensing deformation part 431 can be surrounded by rising steam in the process of boiling water; in this embodiment, the temperature sensing port 102 includes a first temperature sensing sub-port 122 provided in the first inner lid 12, and a second temperature sensing sub-port 132 provided in the second inner lid 13 so as to face the first temperature sensing sub-port 122. In this embodiment, the temperature-sensitive deformation element 431 can be, but not limited to, a steam spring or a thermal memory alloy spring. Specifically, the temperature-sensitive deformable member 431 can absorb heat carried in the rising steam to raise the temperature, and when the temperature of the temperature-sensitive deformable member 431 is raised to a preset temperature, the second end of the temperature-sensitive deformable member 431 is deformed to bend into the temperature-sensitive opening 102, so that the second end of the temperature-sensitive deformable member 431 pushes the latch 412 to the disengagement limiting member 42.

Further, the temperature sensing element 43 further includes a top pillar 432 disposed between the second end of the temperature varying element and the latch 412, and the second end of the temperature varying element indirectly pushes the latch 412 through the top pillar 432. It can be understood that the closer the temperature-sensitive deformation member 431 is to the inner cavity of the electric kettle, the better the temperature-sensitive deformation member 431 is arranged, so that the temperature-sensitive deformation member 431 can absorb heat from rising steam, thus, the distance between the lock catch 412 buckled on the limit bump and the second end of the temperature-sensitive deformation member 431 is larger, and the bending change of the additionally-arranged temperature-sensitive deformation member 431 of the top pillar 432 is transmitted to the lock catch 412 well. Obviously, when the amount of deformation of the temperature-sensitive deformable member 431 is sufficiently large, the top post 432 may be omitted.

In this embodiment, the pot lid body is further provided with a temperature sensing box 14. The temperature sensing box 14 includes a box body 141 detachably connected to the temperature sensing port 102, and a box cover 142 covering the box body 141. Without loss of generality, the box 141 can be mounted at the first temperature-sensing seam allowance 122 through the fixing buckle 123. The two ends of the case 141 are disposed to penetrate through each other, and the temperature sensitive deformation part 431 is fixedly disposed on the case 141, but of course, the end of the case 141 is connected to the temperature sensitive opening 102, so that the temperature sensitive deformation part 431 can be surrounded by the rising steam. The limiting member 42 is disposed on a surface of the box cover 142 away from the box 141, and the top post 432 movably penetrates through the box cover 142. Preferably, the position limiting member 42 is integrally injection-molded on the box cover 142, so as to facilitate mass production. In this embodiment, the temperature sensing box 14 is arranged to realize the integral assembly and disassembly of the limiting member 42 and the temperature sensing element 43, thereby improving the assembly convenience of the lid and facilitating the maintenance and replacement of the temperature sensing element 43.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, which are directly or indirectly applied to the present invention, are included in the scope of the present invention.
