[0050] Please combine Figure 3 In one embodiment, the cover body has a surrounding wall 14 located near the first clearance hole 121, the surrounding wall 14 penetrates the bottom of the cover body, and a second clearance hole 141 is provided at a position corresponding to the first clearance hole 121; the exhaust assembly 25 is located inside the surrounding wall 14, wherein the exhaust nozzle passes through the second clearance hole 141 and the first clearance hole 121 in sequence and is partially exposed outside the cover body.
[0051] In one embodiment, the cover includes a fixed cover 10, a movable cover assembly 20, and a drive assembly 40.
[0052] Please combine Figure 3 The fixed cover 10 is generally a circular groove with a bottom wall 11 and a side wall surrounding the bottom wall 11. The side wall is provided with the first clearance hole 121.
[0053] Referring to the figures, the movable cover assembly 20 includes a circular base plate 21 and a sealing ring 22. The base plate 21 is vertically detachably disposed below the fixed cover 10, and the steam outlet cavity 251 is fixed to the base plate 21 and at least partially located within the fixed cover 10. The sealing ring 22 is sleeved on the periphery of the base plate 21 and abuts against the opening of the kettle body to seal the opening when the movable cover assembly 20 is lowered. Optionally, the sealing ring 22 is made of silicone or rubber.
[0054] The drive assembly 40 is used to controllably drive the movable cover assembly 20 to rise and fall relative to the fixed cover 10. When the movable cover assembly 20 is lowered to the position, it can seal the opening of the kettle body. When the movable cover assembly 20 is raised, it can open the kettle body opening to drain water.
[0055] Please combine Figure 2 , Figure 5 and Figure 12 In one embodiment, the movable cover assembly 20 further includes a base plate 26, which is fixed to the base plate 21 from the bottom side of the base plate 21, and the base plate is provided with the steam outlet 29.
[0056] In one embodiment, since the substrate 21 and the base plate 26 are both made of plastic, and the fixed cover 10 is made of stainless steel, there will be a color difference between the movable cover assembly 20 and the fixed cover 10. To solve the color difference problem, the kettle lid 100 also includes a stainless steel decorative piece 27. The stainless steel decorative cover 30 is placed on the top of the fixed cover 10, and the stainless steel decorative piece 27 is placed on the bottom side of the base plate 26 and covers the base plate. The stainless steel decorative piece 27 has a third clearance hole 271 corresponding to the steam outlet 29. The third clearance hole 271 allows steam to be discharged to the steam outlet 29, and then discharged to the outside of the kettle lid 100 through the steam outlet channel and the steam outlet nozzle 2522.
[0057] In this embodiment, by providing a stainless steel decorative piece, the movable lid assembly 20 is made of a material and color that is essentially the same as the fixed lid 10 when the lid 100 is open, i.e., when the movable lid assembly 20 is raised relative to the fixed lid 10, thus improving the aesthetics of the lid 100. Furthermore, covering the base plate 21 and bottom plate with a stainless steel decorative piece enhances the strength of the movable lid assembly 20 to some extent and protects the bottom plate, preventing wear and deformation.
[0058] Please combine Figures 13 to 17 In another embodiment, a second steam outlet channel is provided between the stainless steel decorative piece 27' and the base plate 26', the second steam outlet channel extending radially along the stainless steel decorative piece and communicating with the steam outlet cavity 251.
[0059] Furthermore, the base plate 26' is recessed towards the substrate 21 to form a first cavity 261', and the stainless steel decorative piece 27' forms a second cavity 271' that communicates with the steam outlet 29 along a direction away from the substrate 21. The second cavity and the first cavity 261' are configured to cooperate with each other. The first cavity 261' is provided with a plurality of first baffles 262' and a plurality of second baffles 263'. The first baffles and the second baffles are alternately arranged in such a way that their extended lines intersect. The first baffles 262' and the second baffles 263' abut against the stainless steel decorative piece 27' and define a flow gap between their close ends. The flow gaps are connected to each other to form the second steam outlet channel.
[0060] In this embodiment, the steam outlet 29 is opened on the stainless steel decorative piece 27', and the bottom plate 26' has a vent 264' at the end of the second steam outlet channel away from the steam outlet 29. The vent 264' on the bottom plate 26' is connected between the second steam outlet channel and the first steam outlet channel.
[0061] The stainless steel decorative piece 27' is provided with a tongue 272', and the base plate 26' is provided with a socket corresponding to the tongue 272'. The stainless steel decorative piece and the base plate are assembled by inserting the tongue into the socket.
[0062] In this embodiment, by setting a second steam outlet channel and a baffle structure in the second steam outlet channel, the steam channel can be extended and the water can be discharged in a staggered manner when the kettle body 200 is tilted, so as to avoid hot water being discharged through the steam exhaust component 25 and further improve the safety of use.
[0063] Please combine Figure 4 , Figures 9-11 In one embodiment, the movable cover assembly 20 further includes a transmission block 23 and a return spring 24. The top end of the transmission block 23 is provided with a transmission inclined surface 231 extending in the circumferential direction. The transmission block 23 is located inside the fixed cover 10 and is fixed to the base plate 21 by a rod-shaped connector 212. The return spring 24 is sleeved on the rod-shaped connector 212 and springs between the transmission block 23 and the fixed cover 10.
[0064] The drive assembly 40 includes a drive knob with a drive block 41. The drive block 41 abuts against the transmission block 23 and slides rotatably along the transmission ramp 231. When the drive knob is in the open state, the drive block 41 is located at the lowest point of the transmission ramp 231, and when the drive knob is in the closed state, the drive block 41 is located at the highest point of the transmission ramp 231.
[0065] Understandably, when the drive knob is turned, the drive knob rotates relative to the fixed cover 10 without producing axial displacement, while the transmission block 23 produces axial displacement relative to the fixed cover 10 under the action of the drive knob. Therefore, in this embodiment, when the lid 100 switches from the open state to the closed state, the drive knob is turned counterclockwise to make the drive block 41 climb up along the transmission ramp 231. This causes the transmission block 23 and the base plate 21 fixed to the transmission block 23 to descend under the pressure of the drive block 41, thereby lowering the part of the movable lid assembly 20 located outside the fixed lid 10 and closing the kettle opening when it reaches the lowest state (the drive block 41 is located at the highest point of the transmission ramp 231). During the closing process of the lid 100, the return spring 24 is compressed and accumulates elastic force. When the lid 100 switches from the closed state to the open state, the drive knob is turned clockwise to make the drive block 41 slide down along the transmission ramp 231. The transmission block 23 rises relative to the fixed lid 10 under the elastic force of the return spring 24, thereby simultaneously raising the other parts of the movable lid assembly 20 and opening the kettle opening.
[0066] Specifically, the rod-shaped connector 212 is fixedly mounted on the base plate 21, and the bottom wall 11 of the fixing cover 10 has a stepped hole 15 corresponding to the rod-shaped connector 212. The transmission block 23 has a screw hole corresponding to the rod-shaped connector. During assembly, screws are passed through the screw holes and the threaded holes on the rod-shaped connector through the stepped hole 15 to fix the transmission block 23 and the rod-shaped connector 212 to each other. The transmission block 23 and the base plate 21 are respectively located on the inner and outer sides of the fixing cover 10. The return spring 24 is sleeved on the rod-shaped connector and presses against the stepped hole 15 between the transmission block 23 and the fixing cover 10.
[0067] The bottom of the transmission block 23 forms a guide block (not shown, the same below), and the bottom wall 11 of the fixed cover 10 has a guide hole 13 corresponding to the guide block. The guide block is inserted into the guide hole 13 and can slide up and down along the guide hole 13.
[0068] In addition, the lid 100 also includes a stainless steel decorative cover 30, which is located on the top of the fixed cover 10 to cover the internal structure of the fixed cover 10 and enhance the aesthetics of the lid 100. Understandably, the drive knob protrudes from the stainless steel decorative cover 30 for the user to grip and rotate, thus opening or closing the lid 100.
[0069] Secondly, this utility model also provides an electric kettle, including a kettle body 200 and a kettle lid 100 disposed on the top of the kettle body 200. The kettle body 200 includes an outer shell and an inner liner 210. The inner liner 210 is housed within the outer shell and has an opening at its top. The outer shell has a spout 220 located above and communicating with the opening. The lid is detachably placed above the inner liner 210, and the steam outlet is located at the spout 220. Since the electric kettle uses the aforementioned kettle lid 100, it inevitably possesses the advantages of the aforementioned kettle lid 100, which will not be elaborated upon here.
