[0029] In one embodiment of the electric kettle of the utility model, please refer to Figures 1 to 7 The electric kettle comprises a kettle body 2, a kettle cover 3 and a kettle cover opening structure 1, and the kettle cover opening structure 1 connects the kettle body 2 and the kettle cover 3. When the kettle cover 3 is opened, the kettle cover can be opened slowly and evenly, reducing the impact force between the kettle cover 3 and the kettle body 2, and playing a good protective role on the kettle cover 3.

[0030] Specifically, refer to Figures 2 to 5The kettle lid opening structure 1 comprises a mounting seat 100, a first connecting rod 200, a push rod 300, a second connecting rod 400, a damper 500 and a lid opening spring 600. The mounting seat 100 is connected to the inner side of the kettle body 2, a mounting portion 110 is provided at the upper end of the mounting seat 100, and a mounting cavity 101 is provided on the inner side of the mounting seat 100. The first connecting rod 200 has a first end 201 and a second end 202, and the first end 201 and the mounting portion 110 are connected with a rotating shaft 120. Specifically, the rotating shaft 120 passes through the first end 201 and the mounting portion 110, so that the first connecting rod 200 and the mounting portion 110 can rotate relative to each other. The second end 202 is fixedly connected to the kettle cover 3; therefore, when the first connecting rod 200 rotates, the kettle cover 3 can be driven to open and close. The damper 500 is arranged in the mounting cavity 101, and the lower end of the push rod 300 slides into the mounting seat 100 and engages with the damper 500. Specifically, a guide groove is provided in the mounting seat 100, and at least the upper end of the guide groove passes through the top of the mounting seat 100, and the mounting cavity 101 is connected to the guide groove, and the push rod 300 extends into the guide groove and engages with the damper 500. One end of the second connecting rod 400 is pivotally connected to the push rod 300, and the other end is pivotally connected to the first connecting rod 200. The cover opening spring 600 is connected to the first connecting rod 200 or the push rod 300, and is used to push the first connecting rod 200 to rotate around the rotation axis, or push the push rod 300 to move upward, drive the first connecting rod 200 to rotate, and open the pot cover 3.

[0031] In this embodiment, when the lid 3 needs to be opened, the lid 3 can be disengaged from the locking structure of the body 2 by pressing the button on the body 2 or the lid 3; therefore, the lid 3 can be pushed upward to open under the elastic force of the lid opening spring 600. In the process of opening the lid 3, the first connecting rod 200 rotates upward around the rotating shaft 120, and then the second connecting rod 400 can be pulled to move the push rod 300 upward. When the push rod 300 moves upward, under the action of the damper 500, a certain damping force can be provided to the push rod 300 to slow down the rising speed, thereby slowing down the speed of opening the lid 3 and reducing the impact force, which plays a good protective role for the lid. And prevent the development adsorbed on the lid 3 from splashing.

[0032] Further, refer to Figure 2 , Figure 3 and Figure 5 The lid opening spring 600 is a torsion spring sleeved on the rotating shaft 120, one end of the torsion spring abuts against the mounting seat 100, and the other end abuts against the first connecting rod 200. Therefore, the first connecting rod 200 can be pushed by the torsion spring to open the pot lid 3. The lid opening spring 600 can also be a compression spring or a tension spring, and the compression spring or the tension spring drives the push rod 300 to move upward to achieve the lid opening effect.

[0033] Furthermore, the damper 500 is a rotary shaft damper, and a gear 501 is provided at the rotating end of the damper 500; the push rod 300 is provided with a rack 301, and the rack 301 is meshed with the gear 501. When the push rod 300 moves upward, the damper 500 can be driven to rotate, thereby generating a damping force on the upward movement of the push rod 300.

[0034] Further, refer to Figure 2 and Figure 5 The damper 500 is a one-way rotation damper. In this embodiment, when the pot cover 3 is closed, it is not affected by the damping force of the damper 500, so it is convenient for the user to close the pot cover 3 on the mouth of the pot body 2.

[0035] Further, refer to Figure 3 and Figure 5 The lower end of the push rod 300 slides through the mounting seat 100, and a limiting portion 310 is further provided at the bottom end of the push rod 300 for limiting the bottom side of the mounting seat 100. When the pot cover 3 is opened, the limiting portion 310 is limited to the bottom side of the mounting seat, thereby limiting the opening angle of the pot cover 3 and limiting the opening angle of the pot cover.

[0036] Further, another embodiment of the damper 500 to achieve the damping effect on the push rod 300, specifically, refer to Figure 6 and Figure 7 The push rod 300 is in sliding or rolling contact with the damper 500. Through the sliding friction or rolling friction between the push rod 300 and the damper 500, a certain resistance is achieved on the push rod 300, thereby achieving a damping effect.

[0037] Further, refer to Figure 6 The damper 500 is an elastic member, and the push rod 300 is provided with an inclined surface 320, which is in contact with the damper 500. As the inclined surface 320 is in contact with the damper 500, when the push rod 300 rises, the damping force of the damper 500 on the push rod 300 gradually increases, which has a decelerating effect on the opening of the pot cover 3. In addition, when the pot cover 3 is closed, it can also be closed quickly.

[0038] Further, refer to Figure 6 The damper 500 includes a compression elastic member 510 and a damping block 520 . The compression elastic member 510 and the damping block 520 are arranged in the installation cavity 101 . The compression elastic member 510 pushes the damping block 520 to fit the inclined surface 320 .

[0039] Further, refer to Figure 7 The damping block 520 is also provided with a roller 530, and the roller 530 is in contact with the inclined surface 320. Rolling friction is realized instead of sliding friction, so that the push rod 300 rises more smoothly.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
