[0044] The slide bar 330 is provided with an upward-facing second meshing tooth 331 and a second straight rib 332. The second straight rib 332 radially protrudes from the circumference of the slide bar 330. The tip of the second straight rib 332 faces upward and coincides with the tip of one of the teeth of the second meshing tooth 331.

[0045] The slide housing 310 is provided with a downward-facing third meshing tooth 311 and a plurality of grooves 312. The third meshing tooth 311 and the plurality of grooves 312 are provided on the inner wall of the slide housing 310. The grooves 312 are vertically extending linear grooves. The slide housing 310 is hollow, and a hole 313 is provided in the center of the slide housing 310 for the top of the slide cover 320 to pass through.

[0046] During assembly, the slide rod shell 310 is fixedly installed in the pot lid body 100, the slide rod top cover 320 is sleeved in the slide rod shell 310, and the top of the slide rod top cover 320 passes through the hole 313, which is convenient for cooperation with the button assembly 200 and can be pushed and moved by the button assembly 200; the slide rod 330 is inserted into the slide rod top cover 320 from bottom to top, and the positions of the first meshing teeth 321 and the second meshing teeth 331 correspond to each other up and down, and at the same time, the first straight rib 322 of the slide rod top cover 320 is located in the groove body 312.

[0047] As shown in Figure 1, the first straight ribs 322, the second straight ribs 332 and the grooves 312 are each provided in plurality, and the number of the first straight ribs 322, the second straight ribs 332 and the grooves 312 is the same; the plurality of first straight ribs 322 on the slide bar top cover 320 are arranged at intervals; the plurality of second straight ribs 332 on the slide bar 330 are arranged at intervals, and the plurality of grooves 312 on the slide bar housing 310 are arranged at intervals.

[0048] The button assembly 200 pushes the slide rod top cover 320 to move toward the slide rod 330, and the first meshing teeth 321 and the second meshing teeth 331 cooperate to enable the slide rod top cover 320 to push the slide rod 330 to move and rotate. The slide rod 330 can be rotated to the first position where the second straight body rib position 332 is meshed with the third meshing teeth 311, so that the cover lock assembly 400 is locked with the pot body 500; and the slide rod 330 can be rotated to the second position where the second straight body rib position 332 enters the groove body 312, so that the cover lock assembly 400 is unlocked with the pot body 500.

[0049] Furthermore, since the first meshing teeth 321 of the sliding rod top cover 320 and the second meshing teeth 331 of the sliding rod 330 are misaligned, the sliding rod 330 is pushed to rotate by a certain angle during the process of the sliding rod top cover 320 pushing the sliding rod 330 to move downward.

[0050] In one embodiment, the third meshing tooth 311 is formed with a large tooth surface 3111 and a small tooth surface 3112, the large tooth surface 3111 and the small tooth surface 3112 are arranged at an angle, and a large tooth surface 3111 and a small tooth surface 3112 are arranged between two adjacent groove bodies 312; as shown in Figure 3, the large tooth surface 3111 and the small tooth surface 3112 are arranged at an angle upward from left to right, and a positioning groove 3113 is formed between the large tooth surface 3111 and the small tooth surface 3112.

[0051] After the slide bar 330 moves and rotates for a certain distance, the second straight rib 332 of the slide bar 330 moves along the large tooth surface 3111 and is then stuck in the positioning groove 3113, so that the slide bar 330 remains in the first position.

[0052] After the slide bar 330 moves and rotates for another displacement, the second straight rib 332 of the slide bar 330 moves along the small tooth surface 3112 and enters the groove 312. The second straight rib 332 abuts against the first straight rib 322, and the slide bar 330 remains in the second position.

[0053] In one embodiment, the lid lock assembly 400 includes a lid lock 410 and a second spring 420. The lid lock 410 has a first inclined surface 411 that contacts the slide bar 330 and a locking portion 412 that interferes with the kettle body 500. The second spring 420 provides elastic force for the lid lock 410 to move in the unlocking direction.

[0054] Specifically, as shown in Figure 5, the slide rod housing 310, the slide rod top cover 320, and the slide rod 330 are coaxial and installed vertically, and the cover lock 410 is installed horizontally; the cover lock 410 currently interferes with the kettle body 500, so that the kettle lid body 100 and the kettle body 500 are locked, and the kettle lid body 100 cannot be removed from the kettle body 500. At this time, the second spring 420 is compressed and provides an elastic force for the cover lock 410 to move in the unlocking direction, that is, the elastic force pointing to the center of the kettle lid body 100 in Figure 5.

[0055] Furthermore, the slide bar 330 is provided with a second inclined surface 333; the second inclined surface 333 of the slide bar 330 cooperates with the first inclined surface 411 of the cover lock 410 to convert the vertical linear movement of the slide bar 330 into a linear movement of the cover lock 410 in the locking direction;

[0056] Specifically, as shown in FIG1 and FIG5 , a second inclined surface 333 is provided at the end of the slide rod 330 , and the second inclined surface 333 cooperates with the first inclined surface 411 ;

[0057] Continuing with FIG5 , the slide bar 330 remains in the first position, the second inclined surface 333 and the first inclined surface 411 conflict with each other, and when the slide bar 330 moves upward, the second inclined surface 333 leaves the first inclined surface 411, and the second spring 420 provides the elastic force of the lid lock 410 pointing to the center of the pot lid body 100 (i.e., the unlocking direction), so that the lid lock 410 moves toward the center of the pot lid body 100, and the lid lock 410 no longer interferes with the pot body 500, and the pot lid body 100 can be taken out.

[0058] As shown in Figure 1, there are multiple groups of cover lock assemblies 400 arranged in a circle, and the slide bar assembly 300 triggers multiple groups of cover lock assemblies 400 at the same time, so that the lid body 100 is more stably locked to the kettle body 500; as shown in Figure 5, the cover lock 410 conflicts with the inner edge 501 of the pot mouth of the kettle body 500, that is, interferes with each other, and the lid body 100 cannot be removed from the kettle body 500. After the cover lock 410 moves in the unlocking direction, the cover lock 410 and the inner edge 501 of the pot mouth no longer conflict, that is, do not interfere with each other, and the lid body 100 can be removed from the kettle body 500.

[0059] Furthermore, the pot lid body 100 is provided with a hole for the locking portion 412 of the lid lock 410 to pass through.

[0060] In one embodiment, the lid body 100 includes: a lid bottom plate 110, a lid panel 120, and a lid inner plate 130; the lid panel 120 and the lid inner plate 130 are combined to form a space inside the lid body 100 for accommodating the slide bar assembly 300 and the lid lock assembly 400;

[0061] The bottom plate 110 of the pot lid is provided with a guide structure for guiding the linear movement of the lid lock 410;

[0062] Specifically, the lid bottom plate 110 and the lid inner plate 130 are connected, and the connection method can be snap fastening or locking screws. The lid bottom plate 110 is provided with a sealing ring 111, which seals the lid body 100 and the pot mouth of the pot body 500 to prevent water from leaking from the gap.

[0063] In one embodiment, one end of the first spring 340 is restricted to the slide bar 330 and the other end is restricted to the bottom plate 110 of the pot lid. The first spring 340 provides a force for the slide bar 330 to move upward.

[0064] Furthermore, as shown in FIG5 , a hole is provided at the bottom of the slide rod 330 , and the first spring 340 can be received in the hole, and the lower end of the first spring 340 is restricted to the bottom plate 110 of the pot cover, so that the first spring 340 is installed more stably.

[0065] In one embodiment, as shown in Figures 1 and 5, the button assembly 200 is mounted on the handle portion 140 of the pot lid body 100. The button assembly 200 includes a button 210 and a third spring 220. The button 210 has a pressing portion 211 and a push rod 212. The push rod 212 passes through the handle portion 140 and acts on the slide rod top cover 320. The third spring 220 is constrained between the pressing portion 211 and the handle portion 140, providing a reset force for the button 210. In addition, the button 210 is constrained with the handle portion 140, allowing the button 210 to be pressed and reset. However, due to the constraint between the button 210 and the handle portion 140, the button 210 cannot be separated from the handle portion 140 under the elastic force of the third spring 220. As shown in Figure 1, the button 210 is provided with a buckle at the bottom of the pressing portion 211, which allows the button 210 to be retained in the handle portion 140.

[0066] Furthermore, the handle portion 140 includes: a handle outer cover 141 and a handle inner cover 142. A channel 1421 for assembling the button assembly 200 is formed inside the handle inner cover 142. After the button 210 is pressed down, it is reset under the reset force of the third spring 220. After resetting, the button 210 is flush with the top of the handle inner cover 142 and covers the channel 1421. The button 210 and the third spring 220 are hidden in the handle inner cover 142 and do not protrude from the handle inner cover 142, keeping the button assembly 200 clean, tidy and beautiful, preventing small substances from entering the pot lid body 100, and ensuring the reliability of the slide assembly 300.

[0067] The specific use of the utility model is further described below:

[0068] The first time you press the button 210:

[0069] As shown in FIG2-3 , when the button 210 is pressed down for the first time, the third spring 220 is compressed. When the force acting on the button 210 disappears, the button 210 is reset by the elastic force of the third spring 220 . The reset button 210 is shown in FIG4 .

[0070] The first straight rib 322 of the sliding rod cover 320 moves downward along the groove 312. The first straight rib 322 and the second straight rib 332 collide with each other in the groove 312. Under the restriction of the groove 312, the sliding rod cover 320 pushes the sliding rod 330 to move linearly downward.

[0071] When the second straight rib 332 leaves the groove 312, the first meshing teeth 321 of the slide bar top cover 320 and the second meshing teeth 331 of the slide bar 330 are misaligned. As the slide bar top cover 320 continues to move downward, it pushes the slide bar 330 downward and rotates. As shown in FIG3 , the first straight rib 322 does not leave the groove 312. As the slide bar 330 moves downward, the first spring 340 is compressed. After the second straight rib 332 leaves the groove 312, the slide bar 330 rotates, causing the tip of the second straight rib 332 to move to the large tooth surface 3111.

[0072] After the first push of button 210 is completed:

[0073] As shown in Figure 4, the force applied to the button 210 is released, and the button 210 is reset under the elastic force of the third spring 220; the sliding rod 330 moves upward under the elastic force of the first spring 340, and the tip of the second straight rib 332 moves along the large tooth surface 3111 and moves to the positioning groove 3113, while the sliding rod top cover 320 is pushed upward by the sliding rod 330.

[0074] As shown in Figures 5-6, after the slide rod 330 is positioned in the first position, the first inclined surface 411 conflicts with the second inclined surface 333, the lid lock 410 conflicts with the inner edge 501 of the pot mouth, and the pot lid body 100 and the pot body 500 remain in a locked state.

[0075] The second time button pressing 210 process:

[0076] As shown in FIG7 , the sliding rod top cover 320 pushes the sliding rod 330 downward, and the second straight rib 332 of the sliding rod 330 leaves the positioning groove 3113 . The sliding rod 330 rotates a displacement, and the second straight rib 332 moves to the small tooth surface 3112 .

[0077] Pressing the button 210 a second time completes:

[0078] As shown in FIG8 , the force applied to the button 210 is released, and the button 210 is reset under the elastic force of the third spring 220 ; the slide rod 330 moves upward under the elastic force of the first spring 340 , and the tip of the second straight rib 332 moves along the small tooth surface 3112 and moves into the groove body 312 for positioning, while the slide rod 330 pushes the slide rod top cover 320 to move upward.

[0079] As shown in Figures 9-10, after the slide rod 330 moves upward, the second spring 420 pushes the lid lock 410 to move to the right (i.e., the unlocking direction) as shown in Figure 9, and the lid lock 410 and the inner edge of the pot mouth 501 do not conflict with each other, and the pot lid body 100 and the pot body 500 remain in the unlocked state.

[0080] Through the above method, the locking and unlocking between the kettle lid body 100 and the kettle body 500 can be quickly completed. When locked, water will rush out when the electric kettle is tilted or tipped over, which can effectively close the kettle mouth and seal the water, preventing the kettle lid body 100 from being rushed out and hot water from rushing out of the kettle mouth to injure the user.

[0081] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
