[0002] An electric kettle is a common appliance used for quickly boiling water. Nowadays, with the improvement of living standards, electric kettles, which use electricity for heating, are increasingly widely used. Electric kettles can determine whether the water has boiled based on the steam emitted, and can automatically shut off the power when the water has boiled. Traditional electric kettles typically consist of a body, a heating element, and a lid. The water spout is directly located on the body, and the lid is often a flip-top design for easy filling. This type of kettle is widely used due to its simple structure and ease of manufacture. However, because the inner liner of this type of kettle is directly connected to the water spout, hot water can easily spill out when the kettle is tilted or tipped over, posing a significant safety hazard and the risk of burns.

[0057] The button assembly 30' is located in the receiving cavity and protrudes partially from the decorative cover 70' through the perforation 71'. It is vertically connected to the fixed cover 10' and the mounting post 22' in an open and closed state. When it receives external pressure, it switches from the open state to the closed state, pressing the mounting post 22' downward to cause the movable cover plate 21' to descend relative to the fixed cover 10' to seal the top opening of the electric kettle. Alternatively, when it switches from the closed state to the open state, it presses the mounting post 22' downward to cause the movable cover plate 21' to rise relative to the fixed cover 10, allowing the top opening of the electric kettle to drain.

[0058] In this utility model, the push-button switch kettle lid 100, when the button assembly 30' is pressed, switching from the open to the closed state, causes the movable cover assembly 20' to descend and seal the kettle opening. When the button is pressed again, switching from the closed to the open state, the movable cover assembly 20' rises, allowing water to flow out of the kettle opening. Thus, the kettle 200's water outlet can be opened or closed by pressing the button, which is convenient and safe. Specifically, when the button is pressed relative to the fixed cover 10', the movable cover assembly 20' blocks the kettle opening, sealing the electric kettle. Compared to existing kettle lid 100 designs that rely on button presses for water dispensing, this design avoids accidental button presses leading to water dispensing, further improving safety.

[0059] In one embodiment, a fixing shell 17' is provided inside the fixing cover 10' surrounding the mounting hole 12'. The fixing shell 17' has an inner cavity 170. On the inner wall of the fixing shell 17', strip grooves 171' and toothed grooves 172' that communicate with the inner cavity 170 are alternately formed. The strip grooves 171' and toothed grooves 172' are both opened from one end of the fixing shell 17' near the bottom wall of the fixing cover 10' to the end away from the bottom wall of the fixing cover 10' and communicate with each other. In the height direction of the fixing shell 17', the length of the strip groove 171' is greater than the length of the toothed groove 172'.

[0060] The button assembly 30' includes a button head 31' and a movable tooth block 32'.

[0061] The button head 31' is cylindrical and has an inner cavity 410. The button head 31' is inserted into the fixed shell 17', and its top end protrudes from the decorative cover 70' to receive external pressing action. The lower end of the button head 31' abuts against the movable tooth block 32'.

[0062] The movable toothed block 32' is stepped and housed within the fixed shell 17'. The top of the movable toothed block 32' is a fixed end 322' and fixed to the mounting post 22'. The lower outer periphery of the movable toothed block 32' extends outward to form a flange 321'. Multiple locking teeth 323' are evenly distributed on the flange. When the movable toothed block 32' is pressed by the button head 31', the locking teeth 323' switch between entering the strip groove 171' or the toothed groove 172'. The return spring 40' is sleeved on the mounting post 22'. The two ends of the return spring 40' abut against the bottom wall of the fixed cover 10' and the movable toothed block 32', respectively, and tend to press the locking teeth 323' against the toothed groove 172'.

[0063] Thus, when the button on the lid 100 is pressed and changes from the open to the closed state, it causes the movable cover plate 21' to move down, blocking the opening at the top of the kettle and sealing the kettle. When the button is released, the locking tooth 323' slides into the toothed groove 172' and locks the movable cover plate 21', keeping it sealed. When the button is pressed again, the lid 100 changes from the closed state to the open state. The movable tooth block 32' rotates at a certain angle under the action of the button head 31' and enters the area where the strip groove 171' is located. When the button head 31' is released, the locking tooth 323' slides upward along the strip groove 171' under the action of the return spring 40'. The movable tooth block 32' causes the movable cover plate 21' to move upward relative to the fixed cover 10', thereby allowing the opening at the top of the kettle body 200 to let water out.

[0064] In one embodiment, the end of the button head 31' is provided with a driving inclined surface, and the locking tooth 323' is provided with a pressure-receiving inclined surface 3231' that slides obliquely with the driving inclined surface. Both the strip groove 171' and the toothed groove 172' are provided with mating inclined surfaces that cooperate with the pressure-receiving inclined surface 3231'. When the button head 31' is pressed, the driving inclined surface acts on the driving inclined surface, rotating the movable tooth block 32' by a preset angle, causing the locking tooth 323' to switch between the strip groove 171' and the toothed groove 172'. By providing mating inclined surfaces, the smoothness of the relative movement between the button head 31', the movable tooth block 32', and the fixed shell 17' is improved.

[0065] In one embodiment, the end of the button head 31' is provided with a drive tip 311', and the drive slope is formed on the side of the drive tip 311'; the number of locking teeth 323' is equal to the number of strip grooves 171' and toothed grooves 172'; the number of drive tips 311' is twice the number of locking teeth 323'.

[0066] In one embodiment, a guide block 312' is provided on the outer periphery of the button head 31', and the guide block 312' is embedded in the strip groove 171' and can slide up and down along the strip groove 171'.

[0067] In one embodiment, the fixed shell 17' extends outward to form a positioning arm, and a positioning hole 173' is provided on the positioning arm. A positioning post 72' is provided at the position corresponding to the positioning hole 173' of the decorative cover 70'. The positioning post 72' is inserted into the positioning hole 173' when the decorative cover 70' is closed on the fixed cover 10'.

[0068] In one embodiment, a plurality of guide posts 24 are evenly arranged around the mounting post 22' on the movable cover plate 21', and the fixed cover 10' has guide holes 16 corresponding to the guide posts 24, and the guide posts 24 are inserted into the guide holes 16.

[0069] In one embodiment, the movable cover 21' has a steam outlet, and a steam switch assembly 25' is provided at the steam outlet. The fixed cover 10' corresponds to the main body and the steam outlet of the steam switch assembly 25', and has a first clearance hole 15' on its bottom wall and a second clearance hole 14' on its side wall. The steam outlet of the steam switch assembly 25' is provided through the second clearance hole 14'.

[0070] In one embodiment, the fixed cover 10' has a surrounding wall 13' near the first clearance hole 15', and the surrounding wall 13' penetrates the bottom wall of the fixed cover 10'; the steam switch assembly 25' is disposed inside the surrounding wall 13', and the steam outlet nozzle passes through the surrounding wall 13' and the second clearance hole 14' and is partially exposed outside the fixed cover 10'.

[0071] Correspondingly, this utility model also relates to an electric kettle, including a kettle body 200' and the aforementioned kettle lid 100', with an opening at the top of the kettle body, and the kettle lid 100' covering the top of the kettle body 200'. The electric kettle of this utility model offers high safety. Furthermore, unlike existing technologies where water is dispensed when a button is pressed down, this utility model seals the kettle when pressed down, and dispenses water only after the button pops up, providing a novel user experience.

[0072] See Figures 25 to 33 This utility model also provides a combined kettle lid according to another embodiment, the effect of which can be found in the following description. Figure 34 and Figure 35 The diagram shows a cross-sectional view of the electric kettle. In this embodiment, the combined kettle lid has two button components. One button component, when pressed, drives the movable cover plate of the movable cover assembly to descend and block the opening at the top of the kettle body to seal the water. This button component is the water-sealing button component. When the other button component is pressed, it releases the locking state of the water-sealing button component, causing it to reset under the action of a return spring, thereby opening the opening at the top of the kettle body to allow water to flow out. This button component is the unlocking button component.

[0073] In this embodiment, the combined kettle lid includes a fixed lid 10'', a movable lid assembly 20'', a button assembly, a return spring, and a decorative lid 70''. The movable lid assembly 20'' can move up and down relative to the fixed lid 10'' to achieve two usage states: sealing water and dispensing water. The button assembly and the return spring together enable the movable lid assembly 20'' to switch between the two usage states. The decorative lid is used to cover the internal components, providing protection and decoration.

[0074] The fixing cover 10'' is preferably made of stainless steel and is generally circular in shape as a groove 11'', with a mounting hole 12'' in the middle of its bottom wall.

[0075] The decorative cover 70'' is made of stainless steel and is placed on the top of the circular groove 11'', forming a storage cavity together with the circular groove 11''.

[0076] The movable cover assembly 20'' includes a movable cover plate 21'' and a sealing ring.

[0077] The movable cover plate 21'' is made of plastic, and a mounting post 22'' is erected in the middle of the movable cover plate 21''. The mounting post 22'' passes through the mounting hole 12'' and can move up and down relative to the fixed cover 10''. The mounting post 22'' has a locking groove 221'' in the middle along the height direction.

[0078] The sealing ring is made of rubber or silicone and is fitted around the outer periphery of the movable cover plate 21''. When the movable cover plate 21'' covers the opening of the pot body, it forms a seal at the contact area between the movable cover plate 21'' and the top structure of the pot body.

[0079] The button assembly includes a water-sealing button assembly 31'' and an unlocking button assembly 32'' that cooperates with the water-sealing button assembly.

[0080] The water-sealing button assembly 31'' includes a water-sealing button cap, a first locking block 33'', and a second locking block 34''. The water-sealing button cap is located in the middle of the decorative cover 70'' and can act downwards on the top of the mounting post 22'' to move the mounting post downwards. The first locking block 33'' is provided with a first locking tongue 332'', and the second locking block 34'' is provided with a second locking tongue 341''. The first locking tongue 332'' and the second locking tongue 341'' can be inserted into the locking groove 221'' from opposite sides, thereby locking the mounting post 22'' through the two locking tongues. This prevents the mounting post from moving in the height direction when the electric kettle is in the water-sealing state, or from being driven out of the locking groove by the two locking tongues, so that the mounting post can be driven to move upwards, causing the movable cover plate 21'' to move upwards, so that the electric kettle is in the water-dispensing state.

[0081] The unlocking button assembly 32'' includes an unlocking keycap and an unlocking key block 321''. The unlocking keycap is mounted on the decorative cover and located on one side of the water-sealing keycap. The unlocking key block 32'' is located below the unlocking keycap and can be pressed down and moved by the unlocking keycap to act synchronously on the first locking block 33'' and the second locking block 34'', causing the locking tongues of the two locking blocks to disengage from the locking grooves 221''.

[0082] The reset spring includes a first reset spring 35'' and a second reset spring 36''. The first reset spring is used to reset (move upward) the mounting post after the locking tongue disengages from the locking groove, thereby driving the movable cover plate to move upward. The second reset spring is used to reset the unlock keycap and the unlock key block after the force applied to the unlock keycap disappears.

[0083] Therefore, when the water-sealing button assembly is pressed, it causes the movable cover plate to move downward to block the opening of the kettle body, thus sealing the water. When the unlocking button assembly is pressed, it releases the locking state of the water-sealing button assembly, allowing it to be reset. By using two button assemblies, the electric kettle can control both the water dispensing and water-sealing states, achieving a good water-sealing effect and the effect of unlocking the water-sealing button assembly.

[0084] In one embodiment, the first locking block 33'' covers the mounting post 22'', and a hollow area 331'' is provided in the middle to make way for the mounting post. The first locking tongue 332'' extends into the hollow area, and a first pressure-bearing inclined surface 333'' is provided on the outer side of the first locking block.

[0085] The second locking block 34'' has the second locking tongue 341'' at one end and the second pressure-bearing inclined surface 342'' at the other end. The second locking block 34'' is located on one side of the first locking block 33'', and the second locking tongue 341'' and the first locking tongue 332'' are at the same height. The second pressure-bearing inclined surface 342'' and the first pressure-bearing inclined surface 333'' are close to each other and have opposite inclination directions, thereby defining a V-shaped groove.

[0086] The unlocking key block 321'' includes a mounting block 3211'' and a pressure block 3212'' and a driving block 3213'' respectively disposed on the upper and lower sides of the mounting block 3211''. The shape of the driving block 3213'' matches the groove defined between the first pressure inclined surface and the second pressure inclined surface. The driving block is provided with a driving inclined surface 3214'' on each of its corresponding two sides of the first pressure inclined surface and the second pressure inclined surface. During the pressing of the unlocking key block 321'', the driving inclined surface 3214'' slides obliquely with the first pressure inclined surface 333'' and the second pressure inclined surface 342'', so that the locking tongues of the first locking block 33' and the second locking block 34'' move in a direction away from each other and separate from the locking groove, thereby realizing the unlocking of the water-sealing key assembly.

[0087] Please combine Figure 27 In addition, the combined lid also includes a retaining spring 37'', which is used to keep the first locking block and the second locking block moving relative to each other, so that their respective locking tongues can be pressed against the locking groove, preventing the locking tongues from disengaging from the locking groove in the unlocked state.

[0088] Specifically, two clamping springs 37'' are provided. One clamping spring 37'' presses against the side of the first locking block 33'' away from the first locking tongue 332'' and the fixed cover 10'', while the other clamping spring 37'' presses against the side of the second locking block 34'' away from the second locking tongue 341'' and the fixed cover 10''. Preferably, spring mounting posts are provided at positions corresponding to the clamping springs 37'' on the first locking block 33'' and the second locking block 34''. Figure 31 334'' and Figure 32 (343'') One end of the clamping spring is fitted onto the spring mounting post to prevent the end of the clamping spring from separating from the locking block.

[0089] It should be noted that the locking grooves can be provided in pairs on opposite sides of the mounting post, or an annular locking groove can be provided around the mounting post; the locking block can be provided in a single way, which can also achieve the locking of the mounting post.

[0090] The above-mentioned methods use knob and button components to drive the movable lid assembly to rise and fall, thereby enabling water supply operation. However, these two methods do not limit the modular lid of this invention. This invention can also use rocker arm, lever, or other drive components to drive the movable lid assembly to rise and fall relative to the fixed lid. As long as the steam outlet is located on the movable lid assembly, the movable lid assembly can seal the opening at the top of the kettle body or allow the opening at the top of the kettle body to be left open under the action of the drive components.
