Description

Technical Field

[0001] This application relates to the field of kettle technology, specifically providing a kettle. Background Technology

[0002] Electric kettles have become a common small appliance in modern households due to their convenience. However, the one-button lid opening mechanism commonly used in the market has a significant safety hazard: the opening action is often too rapid and forceful. This rapid opening causes the hot condensate adsorbed on the inner surface of the lid to be violently flung out due to great inertia, which can easily splash backward onto the operator, causing a risk of burns and seriously affecting user safety and experience.

[0003] To address the aforementioned issues, some existing technologies attempt to slow down the opening speed of the kettle lid by adding damping structures, but these generally suffer from the drawback of complex structures. These solutions often require the introduction of multiple linkage components, such as gear sets or hydraulic buffer devices, which not only increases the difficulty of product assembly and manufacturing costs, but may also lead to decreased structural stability due to the excessive number of components, making it prone to malfunctions such as jamming and wear.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] This application aims to solve the aforementioned technical problem, namely, to resolve the issue of hot condensed water splashing and scalding users due to the excessively fast opening speed of existing electric kettles.

[0006] This application provides a kettle, comprising:

[0007] The body of the teapot;

[0008] A handle is provided on the body of the kettle, and a groove is provided on the top of the handle, and a damping element is provided in the groove;

[0009] The lid has a rotating arm, which is rotatably connected to the handle. During the process of rotating the lid from the closed position to the open position, the rotating arm can partially embed into the groove and contact the damping element and press against each other to provide damping force for the rotation of the lid.

[0010] Optionally, the groove has a first sidewall and a second sidewall disposed opposite to each other, and the rotating arm has a first surface and a second surface disposed opposite to each other. When the rotating arm rotates, the first sidewall contacts and presses against the first surface, and the second sidewall contacts and presses against the second surface.

[0011] Optionally, the distance between the first sidewall and the second sidewall gradually decreases along the rotation direction of the rotating arm.

[0012] Optionally, a first guide post is provided on the first surface, and a first guide groove that mates with the first guide post is provided on the first sidewall; and / or,

[0013] A second guide post is provided on the second surface, and a second guide groove that cooperates with the second guide post is provided on the second side wall.

[0014] Optionally, a first baffle and a second baffle are disposed opposite to each other in the groove, with the first sidewall disposed on the first baffle and the second sidewall disposed on the second baffle.

[0015] Optionally, both the first baffle and the second baffle are elastic plates.

[0016] Optionally, the groove further includes a third sidewall and a fourth sidewall disposed opposite to each other, with the two ends of the first baffle connected to the third sidewall and the fourth sidewall respectively, and the two ends of the second baffle connected to the third sidewall and the fourth sidewall respectively.

[0017] Optionally, the damping element includes a plurality of elastic pillars, which are spaced apart in the groove. When the lid rotates from the closed position to the open position, the rotating arm contacts and presses against the elastic pillars.

[0018] Optionally, the end of the rotating arm is provided with an arc-shaped surface, and when the rotating arm rotates, the arc-shaped surface contacts the elastic column.

[0019] Optionally, the rotating arm is detachably connected to the lid.

[0020] When the lid of the kettle provided in this application is rotated from the closed position to the open position, the rotating arm will gradually be partially embedded into the groove at the top of the handle body as the lid rotates. At this time, the rotating arm and the damping element in the groove come into contact and press against each other. The deformation or frictional resistance of the damping element provides a continuous damping force for the rotation of the lid, thereby effectively slowing down the opening speed of the lid and avoiding the problem of high-temperature condensed water splashing out due to opening the lid too quickly.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] Please refer to Figure 1 and 2 This is an exploded structural diagram of a kettle 1 according to an embodiment of this application. Specifically, the kettle 1 mainly consists of three parts: a power base 15, a kettle body 11, a lid 13, and a handle. In the heating state, the kettle body 11 rests on the power base 15, and the two are connected via an adapter structure to provide power for heating the water inside the kettle body 11. The handle is fixedly mounted on the side wall of the kettle body 11 and adopts a split design, including a handle body 12 and a handle cover 125 that cooperate with each other, forming a complete handle structure through a snap-fit ​​connection. A rotating arm 14 extends from the edge of the lid 13, and the lid 13 is rotatably connected to the handle via a pivot 131 and a torsion spring 16, realizing the opening and closing movement of the lid 13 relative to the kettle body 11.

[0035] Furthermore, a groove 120 adapted to the rotation trajectory of the lid 13 is provided in the top area of ​​the handle body 12. A damping element is fixedly installed inside the groove 120, serving as the core component for slowing down the opening speed of the lid 13. When the lid 13 rotates from the closed position to the open position, the rotating arm 14 gradually partially embeds into the groove 120 at the top of the handle body 12 as the lid 13 rotates. At this time, the rotating arm 14 contacts and presses against the damping element in the groove 120. The deformation or frictional resistance of the damping element provides a continuous damping force for the rotation of the lid 13, thereby effectively slowing down the opening speed of the lid 13 and preventing the problem of hot condensed water splashing out due to excessively fast opening.

[0036] In one implementation, the handle is also equipped with a lid-opening button 124 and a button spring 123, which together with the rotating arm 14 form a linkage structure to jointly control the opening and resetting action of the lid 13.

[0037] Reference Figure 3 and Figure 4 , Figure 3 The diagram shows a cross-sectional view of the kettle 1 when the lid 13 is in the closed position. Figure 4 This diagram shows a cross-sectional view of the kettle 1 when the lid 13 is in the open position. (Reference) Figure 5 and Figure 6The rotating arm 14 includes a first rotating arm 141 and a second rotating arm 142, which are spaced apart to form a parallel double-arm structure. The first rotating arm 141 serves as a trigger linkage component, with its end corresponding to the cover opening button 124 on the handle. The second rotating arm 142 serves as a damping component, with its position corresponding to the damping element on the top of the handle body 12, and is responsible for generating a damping effect during rotation.

[0038] Specifically, as shown in the figure, when the lid opening button 124 is in the unpressed state and the lid 13 is in the closed position, the rotating arm 14 is not embedded in the groove 120 of the handle body 12. The first rotating arm 141 abuts against the linkage end of the lid opening button 124, forming a force balance with the compressed button spring 123. The second rotating arm 142 remains separated from the damping element, and the lid 13 tightly covers the top opening of the kettle body 11, achieving a seal. When the user presses the lid opening button 124, the button structure and the first rotating arm 141 undergo relative displacement, releasing the constraint on the button spring 123. The spring force pushes the first rotating arm 141, causing the entire rotating arm 14 to rotate, thereby driving the lid 13 to open. During this process, the second rotating arm 142 gradually embeds into the groove 120 as the whole rotates, contacting and pressing against the damping element in the groove 120. The damping force slows down the rotation speed, gradually achieving the switch from the closed position to the open position.

[0039] Furthermore, during the transition from the closed position to the open position, the second rotating arm 142 gradually engages with the groove 120 at the top of the handle body 12 as the lid 13 rotates. It contacts and presses against the damping element within the groove 120. The resistance generated by the deformation or friction of the damping element continuously acts on the second rotating arm 142, effectively offsetting part of the spring force, allowing the lid 13 to open slowly and smoothly, avoiding excessively fast opening due to excessive spring force. When the lid 13 rotates to the fully open position, the pressing action between the second rotating arm 142 and the damping element reaches a stable state, and the lid 13 remains in the open position. To close the lid 13, the user can manually press down on the lid 13. The second rotating arm 142 rotates in the opposite direction and exits the groove 120, and the button spring 123 is recompressed and stored until the lid 13 returns to the closed position. The lid opening button 124 also springs back to its original position, awaiting the next operation.

[0040] It should be noted that the specific structure of the cover-opening button 124 and its cooperation with the button spring 123 to trigger the cover-opening action is a conventional design well known to those skilled in the art, and will not be described in detail here.

[0041] The damping element can take many specific forms. For example, the damping element is a rubber damping block. When the rotating arm 14 is embedded in the groove 120, the rubber damping block is deformed by the compression of the rotating arm 14. The damping force is formed by the elastic resistance of the rubber itself and the surface friction, which slows down the rotation speed of the rotating arm 14.

[0042] In one embodiment, reference Figure 7 The groove 120 has a first sidewall 1201 and a second sidewall 1202 arranged opposite to each other, and the second rotating arm 142 has a first surface 1401 and a second surface 1402 arranged opposite to each other. When the user presses the lid opening button 124 to drive the lid 13 to rotate from the closed position to the open position, the second rotating arm 142 moves accordingly and partially embeds itself into the groove 120. During this embedding and rotation process, the first surface 1401 of the second rotating arm 142 contacts the first sidewall 1201 of the groove 120 and begins to press against each other. At the same time, the second surface 1402 of the second rotating arm 142 also contacts the second sidewall 1202 of the groove 120 and presses against each other. This double-sided pressing structure can continuously generate damping through the friction of the contact surfaces, and transmit it to the lid 13 through the second rotating arm 142, forming a balanced and stable damping effect, which helps the lid 13 maintain a stable posture during rotation.

[0043] Furthermore, along the rotation direction of the second rotating arm 142, the distance between the first sidewall 1201 and the second sidewall 1202 gradually decreases, and the groove 120 forms a wedge-shaped or narrowed space on the movement path of the second rotating arm 142. As the opening angle of the lid 13 increases, the portion of the second rotating arm 142 embedded in the groove 120 becomes deeper and deeper, and its first surface 1401 and second surface 1402 are forced to fit more tightly and be more strongly squeezed against the first sidewall 1201 and the second sidewall 1202 respectively in an increasingly narrow space. This design causes the pressure between the first surface 1401 and the first sidewall 1201, and between the second surface 1402 and the second sidewall 1202, to gradually increase as the second rotating arm 142 rotates from its initial embedded position into the depth of the groove 120. This allows the opening speed of the lid 13 to gradually slow down from the initial stage to the fully opened stage, avoiding the shaking of the lid 13 caused by sudden changes in damping force. It effectively counteracts the thrust of the button spring 123 and further reduces the risk of condensed water splashing out due to inertia through a smooth deceleration process.

[0044] In one specific embodiment, the lid 13 is detachably connected to the rotating arm 14, which facilitates the separate processing of the rotating arm 14.

[0045] In a specific implementation, refer to Figure 5On the side closest to the body 11, the distance between the first sidewall 1201 and the second sidewall 1202 is relatively small. As it extends away from the body 11 and closer to the outside of the handle, the distance between the first sidewall 1201 and the second sidewall 1202 gradually increases, showing a continuous change trend from narrow to wide. When the second rotating arm 142 starts to rotate under the drive of the button spring 123, its first surface 1401 first contacts the side of the first sidewall 1201 near the wide gap, and the second surface 1402 contacts the side of the second sidewall 1202 near the wide gap. At this time, the pressure on both sides is weak and the damping force is small, which facilitates the smooth start of the rotation of the second rotating arm 142. As the second rotating arm 142 continues to rotate and gradually moves closer to the body 11, the contact positions of the first surface 1401 and the first side wall 1201, and the second surface 1402 and the second side wall 1202, transition to the narrower gap side. The squeezing force of the two side walls on the second rotating arm 142 gradually increases, and the damping force also increases steadily. This causes the rotation speed of the lid 13 driven by the second rotating arm 142 to gradually slow down, achieving a smooth transition from initial rotation to slow opening.

[0046] In one embodiment, a first baffle 121 and a second baffle 122 are disposed opposite each other within the groove 120. A first sidewall 1201 is disposed on the first baffle 121, and a second sidewall 1202 is disposed on the second baffle 122. This structural design allows the contact and pressing force between the sidewall and the second rotating arm 142 to be directly transmitted to the baffle. This force drives the first baffle 121 and the second baffle 122 to undergo adaptive deformation to the outside or inside, providing an adjustable buffer space for the generation of damping force.

[0047] In one embodiment, both the first baffle 121 and the second baffle 122 are elastic plates. As elastic plates, their material itself has good flexibility and resilience. When subjected to the compressive force of the second rotating arm 142, they can more easily bend or tilt, absorbing part of the impact force through the deformation process. At the same time, they use their own elastic restoring force to form a reverse force, further enhancing the damping effect on the second rotating arm 142. When the second rotating arm 142 exits the groove 120, the deformed baffle can automatically reset due to elasticity, maintaining a stable structural state for the next opening and closing operation of the lid 13, and avoiding the attenuation of damping performance due to long-term deformation.

[0048] In one embodiment, the groove 120 further includes a third sidewall and a fourth sidewall disposed opposite to each other. The two ends of the first baffle 121 are respectively connected to the third sidewall and the fourth sidewall, and the two ends of the second baffle 122 are respectively connected to the third sidewall and the fourth sidewall, which helps to improve the stability of the overall structure.

[0049] In one embodiment, a first guide post is provided on the first surface 1401, and a first guide groove that mates with the first guide post is provided on the first sidewall 1201. A second guide post is provided on the second surface 1402, and a second guide groove that mates with the second guide post is provided on the second sidewall 1202. The first guide post, the first guide groove, the second guide post, and the second guide groove are not shown in the figure.

[0050] When the second rotating arm 142 rotates within the groove 120, the first guide post slides along the first guide groove, and the second guide post slides along the second guide groove. Through the cooperation of the guide post and the groove, the rotation trajectory of the second rotating arm 142 can be precisely constrained, preventing it from deviating or shaking during rotation. This ensures that the first surface 1401 and the first side wall 1201, and the second surface 1402 and the second side wall 1202 always maintain a stable contact and compression state, making the damping force more uniform and continuous. It also makes the rotation process of the second rotating arm 142 smoother and reduces jamming.

[0051] In one embodiment, the damping element includes multiple elastic pillars spaced apart within the groove 120. When the lid 13 rotates from the closed position to the open position, the second rotating arm 142 contacts and presses against the elastic pillars. The elastic pillars can be made of materials with good elasticity, such as rubber or silicone, and are distributed along the rotation trajectory within the groove 120. As the second rotating arm 142 rotates and embeds into the groove 120 with the lid 13, it contacts the elastic pillars at different positions in sequence. By compressing the elastic pillars, it causes them to deform, and the rebound force of the elastic pillars forms a continuous damping force, thereby gradually slowing down the rotation speed of the second rotating arm 142 and preventing the lid 13 from opening too quickly. This structure does not require complex sidewall fittings; the buffering effect can be achieved solely through the deformation characteristics of the elastic pillars themselves, offering advantages such as simple structure and convenient assembly.

[0052] Furthermore, the end of the second rotating arm 142 is provided with an arc-shaped surface, which contacts the elastic column when the second rotating arm 142 rotates. The arc-shaped surface design changes the contact between the second rotating arm 142 and the elastic column from point contact to smooth surface contact, reducing local stress concentration during the extrusion process and preventing excessive wear or breakage of the elastic column due to uneven force. At the same time, as the arc-shaped surface rotates with the second rotating arm 142, the contact position with the elastic column will naturally transition, causing the extrusion force to change gradually, ensuring smooth damping force output, reducing the feeling of jamming during rotation, and improving the smoothness of the opening and closing operation of the lid 13 and the service life of the components.

[0053] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
