[0018] The present invention will be further described below with reference to the drawings and exemplary embodiments, in which all the same reference numerals refer to the same parts, and detailed descriptions of known techniques will be omitted if they are not necessary to illustrate the features of the present invention.

[0019] 1 to 12, the present invention relates to a kettle lid 100, a kettle 200, and an electric kettle consisting of the kettle lid 100 and the kettle 200. The kettle lid 100 can be controlled to open one of the exhaust hole 121 and the water outlet 2121 and close the other during use, and has excellent safety performance and is easy to use for users.

[0020] 1 to 6, the kettle lid 100 includes a bottom case 10, a decorative lid 20, a driving lever 30 and a transmission unit 40. As shown in FIG.

[0021] An outlet hole 122 is formed on one radial side of the bottom case 10, penetrating the bottom surface of the bottom case 10. When the kettle lid 100 is attached to the kettle 200, the outlet hole 122 allows water vapor in the kettle 200 to flow into the bottom case 10.

[0022] The decorative cover 20 covers the top of the bottom case 10 and is connected to the bottom case 10 to define a storage space. An exhaust hole 121 is formed in the decorative cover 20. The exhaust hole 121 communicates with the blowing hole 122, so that water vapor in the kettle is exhausted through the exhaust hole 121, thereby reducing the pressure in the kettle. In one embodiment, the decorative cover 20 is engaged and connected to the bottom case 10, making it easy to assemble with the bottom case.

[0023] The driving lever 30 is slidably mounted on the bottom case 10 and can be controlled to open the exhaust hole 121 when moving along a first direction, and close the exhaust hole 121 when moving along a second direction opposite to the first direction. In one embodiment, the driving lever 30 has a pusher plate 34 protruding from the decorative cover 20, which facilitates a user to press the driving lever 30 to slide.

[0024] The transmission unit 40 is provided on one side of the bottom case 10 away from the exhaust passage 120, and when the driving lever 30 moves along the first direction, the transmission unit 40 is pushed down by the driving lever 30 and moves downward relative to the bottom case 10. As a result, the transmission unit 40 acts on the water outlet opening and closing unit 220 of the kettle 200, causing the water outlet opening and closing unit 220 to close the water outlet 2121 of the kettle 200. On the other hand, when the driving lever 30 moves along the second direction, the transmission unit 40 moves upward relative to the bottom case 10 and causes the water outlet opening and closing unit 220 to open the water outlet 2121 of the kettle 200.

[0025] In the kettle lid 100 of the present invention, the steam exhaust hole 121 is opened and closed by the driving lever 30. When the driving lever 30 opens the exhaust hole 121, it indirectly acts on the water outlet opening and closing unit 220 in the kettle via the transmission unit 40 to close the water outlet 2121. As a result, one of the exhaust hole 121 and the water outlet 2121 is opened while the other is closed, which is convenient for the user and improves the safety of the kettle 200.

[0026] In one embodiment, a transmission unit mounting groove 110 is provided on one side of the bottom case 10 away from the blowing hole 122. The transmission unit 40 is installed in the transmission unit mounting groove 110 so as to be movable up and down. A sliding passage is formed between the blowing hole 122 and the transmission unit mounting groove 110. The driving lever 30 is provided in the sliding passage.

[0027] By providing a sliding passage between the outlet hole 122 and the transmission unit mounting groove 110, the driving lever 30 slides within the sliding passage, and the sliding trajectory of the driving lever 30 is made straight, which facilitates the design of the kettle lid 100 and more accurately controls the exhaust function of the kettle 200 and the blocking function of the water outlet 2121 by the driving lever 30.

[0028] In one embodiment, an exhaust passage 120 is formed between the blowing hole 122 and the exhaust hole 121. The exhaust passage 120 includes a ventilation column 123. The ventilation column 123 is provided with ventilation holes penetrating both upper and lower ends.

[0029] The driving lever 30 includes a sealing cover plate 31 and a pressing head 32, which are integrally molded. The pusher plate 34 is disposed between the sealing cover plate 31 and the pressing plate, and protrudes upward from the decorative cover 20. The sealing cover plate 31 can cover the ventilation hole of the ventilation column 123 when the driving lever 30 moves along the second direction. The pressing head 32 biases the transmission unit 40 when the driving lever 30 moves along the first direction.

[0030] In one embodiment, a position restriction protrusion 33 is provided on the bottom surface of the drive lever 30 between the sealing cover plate 31 and the presser head 32. The position restriction protrusion 33 is provided with a position restriction groove 331 with an opening facing downward. The bottom case 10 is provided with a spring pin 50 corresponding to the position restriction protrusion 33. The spring pin 50 can be elastically engaged in the position restriction groove 331.

[0031] The position restriction groove 331 and the spring pin 50 are provided to form a locking member, thereby locking the driving lever 30 and preventing the automatic return of the driving lever 30 from affecting the user's use, thereby improving user-friendliness and safety.

[0032] In one embodiment, the transmission unit 40 includes a transmission block 42 and a presser lever 421 fixed to the transmission block 42 below the transmission block 42. When the transmission block 42 receives an acting force from the driving lever 30, the presser lever 421 moves downward and penetrates a first retreat hole 111 provided in advance in the bottom case 10 to act on the water outlet opening and closing unit 220.

[0033] In one embodiment, a guide groove 112 extending in the vertical direction is provided in the bottom case 10. The guide groove 112 is provided in the transmission unit mounting groove 110 and is located between the first evacuation hole 111 and the blowing hole 122.

[0034] The transmission unit 40 further includes a support block 41 and a guide lever 411. The support block 41 is fixed to one side of the transmission block 42 adjacent to the outlet hole 122, and is supported below the driving lever 30. The guide lever 411 is inserted into the guide groove 112 so as to be movable up and down.

[0035] The transmission block 42 has a transmission inclined surface 420. The transmission inclined surface 420 is inclined upward from the support block 41 to the transmission block 42. Thus, when the driving lever moves along the first direction, it gradually presses down the transmission block 42.

[0036] In this way, when the drive lever 30 moves from the support block 41 toward the transmission block 42 and along the transmission inclined surface to press down the transmission block 42, the movement of the transmission block 42 and the pressure lever 421 is regulated and guided, preventing the transmission block 42 from rotating and allowing the water outlet 2121 to be closed normally by the drive lever 30.

[0037] As a second aspect, the present invention further provides a kettle 200. The kettle 200 includes a kettle body 210, a handle connected to one side of the kettle body 210, and a water outlet opening and closing unit 220.

[0038] A spout 211 is provided on one side of the top end of the kettle body 210 away from the handle. A water stop ring 212 that engages with the kettle lid 100 is provided inside the kettle body 210. A water outlet 2121 that communicates with the spout 211 is provided on the water stop ring 212 at a location close to the spout 211.

[0039] The water outlet opening and closing unit 220 is connected to the kettle body 210 adjacent to the water outlet 2121, and includes a sealing block 2223 that engages with the water outlet 2121. The sealing block 2223 is capable of blocking the water outlet 2121 by a transmission unit 40.

[0040] The water outlet 2121 is a constantly open water outlet. The sealing block 2223 is separated from the water outlet 2121 when the kettle lid 100 does not cover the kettle or the presser lever 421 does not protrude from the bottom case 10. By keeping the water outlet 2121 constantly open and locating it close to the spout 211, it is easy to completely drain the water in the kettle body 210, and avoids the problem of water accumulating in the kettle 200 causing deterioration of the water and odor.

[0041] In one embodiment, the water outlet opening and closing unit 220 includes a mounting base 221 , a raised plate 222 and a return spring 223 .

[0042] The mounting base 221 is fixed to the inside of the kettle body 210. The raised plate 222 includes a pressing end 2222, a sealing end 2221, and a rotating shaft 2220 disposed laterally between them, which are integrally molded. The sealing block 2223 is provided on the sealing end 2221. The raised plate 222 is rotatably attached to the mounting base 221 by the rotating shaft 2220. The pressing end 2222 is provided below a pressing lever 421, and when it receives downward pressure from the pressing lever 421, it moves downward, thereby lifting up the sealing end 2221 to block the water outlet 2121. The return spring 223 is elastically compressed between the pressing end 2222 and the mounting base 221, and when the force acting on the pressing end 2222 by the pressing lever 421 is released, it causes the pressing end 2222 to rise and return, and the sealing end 2221 moves the sealing block 2223 away from the water outlet 2121, opening the water outlet 2121.

[0043] In one embodiment, the pressing end 2222 is provided below the water stop ring 212. The water stop ring 212 is provided with an evacuation notch 2122 corresponding to the pressing lever 421. Thus, the pressing lever 421 passes through the evacuation notch 2122 and biases against the pressing end 2222. The water outlet opening and closing unit 220 is provided below the water stop ring 212, preventing the water outlet opening and closing unit 220 from being exposed from the kettle port, improving the appearance of the kettle 200.

[0044] In a third aspect, the present invention further provides an electric kettle, including the above-mentioned kettle 200, the above-mentioned kettle lid 100 covering the top end of the kettle 200, and an electric base 300 provided below the kettle 200. The electric base 300 receives electric energy to heat the liquid in the kettle 200. Since the electric kettle has the above-mentioned kettle lid 100 and kettle 200, it necessarily has the advantages of the kettle lid 100 and the kettle 200, and the details thereof will be omitted here.

[0045] Although the above describes some exemplary embodiments of the present invention, those skilled in the art will appreciate that these exemplary embodiments can be modified without departing from the principles or spirit of the present invention, and the scope of the present invention is limited by the claims and their equivalents.
