[0050] The first end of the lever is used to actuate the mechanical valve, and the second end is attracted to the bottom end of the float. When the second end of the lever and the bottom end of the float are attracted to each other, the lever actuates the mechanical valve to open, and when the second end of the lever is separated from the bottom end of the float, the lever actuates the mechanical valve to close.

[0051] Specifically, when the water level is low, the bottom of the float is in a lower position, the second end of the lever and the bottom of the float are attracted to each other, the lever actuates the mechanical valve to open, and water can flow into the water storage part. When the water level is high and the float position rises, causing the second end of the lever to separate from the bottom of the float, the lever actuates the mechanical valve to close, and water stops flowing into the water storage part.

[0052] The float is connected to a float connecting rod, the bottom end of the float connecting rod forms a first part, and the second end of the lever forms a second part attracted to the first part.

[0053] The water storage part is provided with a float connecting rod guiding structure for guiding the float connecting rod to ensure that the first part / component at the bottom end of the float connecting rod is always opposite to the second part / component at the second end of the lever.

[0057] A float 12 , a float connecting rod 13 and a first part / component 14 are arranged in the kettle body 1 .

[0058] The float 12 is connected to the float connecting rod 13 .

[0059] The float 12 is connected to the top of the float connecting rod 13.

[0060] The first part / piece 14 is located at the bottom end of the float connecting rod 13 .

[0061] The first portion refers to a part of the float connecting rod 13 , and the first piece refers to an independent piece installed on the float connecting rod 13 .

[0062] The base 2 includes a water inlet pipeline 21 , a second top-opening valve 22 , a mechanical valve 23 and a lever 24 .

[0063] The water inlet pipeline 21 is located in the base 2 and has an inlet and an outlet. The inlet is located on the side wall of the base 2 and the outlet is connected to the second top-opening valve 22 .

[0064] The second top-opening valve 22 is located in the base 2 , and the second top-opening valve 22 is connected to the outlet of the water inlet pipeline 21 .

[0065] The top surface of the base 2 is provided with a second top-opening valve 22, which is a mechanical valve. When the kettle body 1 is separated from the base 2, the second top-opening valve 22 is closed and in a closed state; when the kettle body 1 and the base 2 are installed, the second top-opening valve 22 is pushed open by the kettle body 1 and is in an open state.

[0066] That is, when the kettle body 1 and the base 2 are installed, the first top-opening valve 11 and the second top-opening valve 22 are both opened, so that the outlet of the water inlet pipe 21 of the base 2 is connected to the kettle body 1 .

[0067] The mechanical valve 23 is located on the water inlet pipeline 21, and is used to cut off or open the water inlet pipeline 21. When the mechanical valve 23 is in an open state, the water inlet pipeline 21 is open, and when the mechanical valve 23 is in a closed state, the water inlet pipeline 21 is cut off.

[0068] The middle part of the lever 24 is rotatably connected to the base 2 , the first end of the lever 24 is used to actuate the mechanical valve 23 , and the second end is provided with a second part / component 25 attracted to the first part / component 14 .

[0069] The middle portion of the lever 24 does not specifically refer to the exact center of the lever 24 , but is located between the first end and the second end.

[0070] The second portion refers to a part of the lever 24 , and the second piece refers to an independent piece installed on the lever 24 .

[0071] The first part / component 14 and the second part / component 25 have a mutual attraction.

[0072] The first part / component 14 and the second part / component 25 are both magnetic, and the relative parts have opposite magnetic poles.

[0073] In some embodiments, the first part / component 14 is metal and the second part / component 25 is a magnet.

[0074] In some embodiments, the first part / piece 14 is a magnet and the second part / piece 25 is a metal.

[0075] When the kettle body 1 and the base 2 are installed together, the first top-opening valve 11 and the second top-opening valve 22 are sealed and connected and pushed open to each other. There is no water in the kettle body 1, or the water level is not enough to float the float 12 until the second part / component 25 is separated from the first part / component. The second part / component 25 is adsorbed on the base 2 under the attraction between the second part / component 25 and the first part / component 14, and the lever 24 actuates the mechanical valve 23 to open, and the water inlet pipe 21 is connected, so that water can enter the kettle body 1 through the water inlet pipe; as the kettle body 1 is 1, the water level in the kettle body 1 rises, and the float 12 drives the first part / component 14 to float up under the action of buoyancy, thereby separating from the second part / component 25. When the water level in the kettle body 1 rises to the point where the attraction between the first part / component 14 and the second part / component 25 is insufficient to allow the second part / component 25 to be adsorbed on the base 2, the second part / component 25 is detached from the base 2, the second end of the lever 24 moves downward, and the first end of the lever 24 moves upward, actuating the mechanical valve 23 to close, the water inlet pipe 21 is cut off, and water stops flowing into the kettle body 1.

[0076] When the kettle body 1 is separated from the base 2, the first top-opening valve 11 and the second top-opening valve 22 lose their top-opening force and are both closed, the lever 24 actuates the mechanical valve 23 to close, and the water inlet pipeline 21 is cut off.

[0077] A float connecting rod guide structure 15 for guiding the float connecting rod 13 is provided in the kettle body 1 to ensure that the float connecting rod 13 always rises and falls at a specific position during the process of the float 12 rising and falling to drive the float connecting rod 13 to rise and fall, that is, the first part / component 14 always moves in the vertical direction and basically does not move in the horizontal direction, to ensure that the first part / component 14 on the float connecting rod 13 can always be opposite to the second part / component 25 on the lever 24, so that when the first part / component 14 descends to the bottom surface of the kettle body 1, it can be attracted to the second part / component 14.

[0078] The float connecting rod guide structure 15 is a guide cylinder arranged in the vertical direction, and its inner diameter is matched with the outer diameter of the float connecting rod 13 or is slightly larger than the outer diameter of the float connecting rod 13 .

[0079] A float guide and limit structure 16 for guiding and limiting the float 12 is arranged in the kettle body 1 .

[0080] The float guide limiting structure 16 is a float guide cylinder arranged in the vertical direction.

[0081] The top of the float guide cylinder is closed or has a limiting structure to prevent the float 12 from escaping from the float guide limiting structure 16 .

[0083] The bottom surface of the kettle body 1 is provided with a recessed portion, and the top surface of the base 2 is provided with a raised portion matched with the recessed portion. When the base 2 and the kettle body 1 are installed together, the raised portion on the top surface of the base 2 is inserted into the recessed portion on the bottom surface of the kettle body 12.

[0084] The concave portion is located at the center of the bottom surface of the kettle body 1 , and the convex portion is located at the center of the top surface of the base 2 .

[0085] A first top-opening valve 11 is provided at the bottom of the kettle body 1. The first top-opening valve 11 is a mechanical valve. When the kettle body 1 is separated from the base 2, the first top-opening valve 11 is closed and in a closed state; when the kettle body 1 is installed with the base 2, the first top-opening valve 11 is pushed open by the base 2 and is in an open state.

[0086] The first top-opening valve 11 is located in the inner recess.

[0087] exist Figure 2 , 6 In the example, the kettle body 1 is provided with a through hole 18 and a cylindrical structure 17, wherein the through hole 18 is located in the cylindrical structure 17. The first top-opening valve 11 includes a first valve core 111 located in the cylindrical structure 17, the first valve core 111 is connected to the cylindrical structure 17 via a first reset element 112, and the first valve core 111 is used to open or close the through hole 18.

[0088] The through hole 18 and the cylindrical structure 17 are both located in the concave portion of the bottom surface of the kettle body 1 .

[0089] The first valve core 111 is provided with a sealing ring that matches the through hole 18. When the first valve core 111 is not acted upon by an external force, the first reset element 112 causes the first valve core 111 to be in a closed state that closes the through hole 18. Figure 2When the first valve core 111 is pushed by an external force, the external force overcomes the force of the first reset element 112, so that the first valve core 111 moves upward to an open state where the through hole 18 is opened, as shown in FIG. Figure 6 shown.

[0090] The second top-opening valve 22 is located at the raised portion of the top surface of the base 2. A through hole is provided on the raised portion, and the water outlet of the second top-opening valve 22 is connected to the through hole.

[0091] exist Figure 3 , 6 In the example of FIG. 2 , the second top-opening valve 22 includes a second valve body 221 , a second valve core 222 and a sealing sleeve 223 . The second valve core 222 is used to open or close the second valve body 221 .

[0092] The second valve body 221 includes a base and a valve cover. The base is provided with a water inlet, and the valve cover is provided with a water outlet.

[0093] The second valve body 221 is connected to the second valve core 222 via a second reset element 224. When the second valve core 222 is not acted upon by an external force, the second reset element 224 causes the second valve core 222 to be in a closed state of closing the second top-opening valve 22. Figure 3 When the second valve core 222 is pushed by an external force, the external force overcomes the action of the second reset element 224, so that the second valve core 222 moves downward to the open state of the second top-opening valve 22, as shown in FIG. Figure 6 shown.

[0094] The sealing sleeve 223 is located in the second valve body 221, and a positioning member 225 for fixing the sealing sleeve 223 is provided in the second valve body 221. The second valve body 221 contacts the sealing sleeve 223 to close the second top-opening valve 22, and the second valve body 221 and the sealing sleeve 223 separate to open the second top-opening valve 22.

[0095] like Figure 6 As shown, when the kettle body 1 and the base 2 are installed together, the sealing sleeve 223 is sleeved on the cylindrical structure 17 to achieve a sealed connection between the first top-opening valve 11 and the second top-opening valve 22 .

[0096] The second end of the lever 24 is rotatably connected to a lever connecting rod 241 , a second component 25 is disposed at the top of the lever connecting rod 241 , and a lever connecting rod guiding structure 26 for guiding the lever connecting rod 241 is disposed on the base 2 .

[0097] The lever connecting rod guide structure 26 is a guide cylinder arranged in the vertical direction to ensure that the second part / component 25 is always opposite to the first part / component 14.

[0098] The lever 24 has a lever resetting element 242 for resetting the lever 24 .

[0099] Specifically, a lever reset element 242 is provided between the second end of the lever 24 and the base 2 , and the lever reset element 242 is used to generate downward pressure or pulling force on the second end of the lever 24 so that the first end of the lever 24 rises to close the mechanical valve 23 .

[0100] like Figure 4 , 7 As shown, the mechanical valve 23 includes a valve body 231 and a valve core 232 , the valve body 231 and the valve core 232 are connected via a reset element 233 , and a magnet 243 is provided at the first end of the lever 24 , which is used to drive the valve core 232 to move, thereby actuating the opening and closing of the mechanical valve 23 .

[0101] A valve plate 234 is provided in the valve body 231. The valve body 231 is provided with a water inlet, a water outlet and a water passage connecting the water inlet and the water outlet. A pressure relief hole 235 and a pressurizing hole 236 are provided on the valve plate 234. A valve cavity 237 is formed between the lower part of the valve plate 234 and the valve body 231. When the valve core 232 blocks the pressure relief hole 235, water enters the valve cavity 237 through the pressurizing hole 236, and the pressure in the valve cavity 237 increases, so that the valve plate 234 overcomes the water inlet pressure and blocks the water passage upward, thereby closing the valve body 231. When the valve core 232 opens the pressure relief hole 235, the water in the valve cavity 237 flows out of the valve cavity 237 through the pressure relief hole 235, and the pressure in the valve cavity 237 decreases. Under the action of the water inlet pressure, the valve plate 234 opens the water passage downward, thereby opening the valve body 231.

[0102] The magnet 243 is a magnetic ring or is arranged in a ring shape. The magnet 243 is mounted on the mechanical valve 23 to ensure the force of the magnet 243 on the valve core 232 .

[0103] In order to facilitate the installation of the magnet 243 , a magnet fixing sleeve 244 is rotatably connected to the first end of the lever 24 , and the magnet 243 is installed in the magnet fixing sleeve 244 .

[0104] like Figure 1 As shown, when the kettle body 1 is separated from the base 2, the first top-opening valve 11 and the second top-opening valve 22 lose their top-opening force and are both closed, the force of the first part / component 14 on the second part / component 25 disappears, and the lever connecting rod 241 moves downward under the action of the lever resetting element 242, driving the second end of the lever 24 to move downward, and the first end of the lever 24 moves upward, driving the magnet 243 to move upward, driving the valve core 232 of the mechanical valve 23 to move upward, and the valve core 232 blocks the pressure relief hole 235, closing the mechanical valve 23, and the water inlet pipeline 21 is cut off.

[0105] When the kettle body 1 and the base 2 are installed together, the sealing sleeve 223 of the second top-opening valve 22 is sleeved on the cylindrical structure 17 to achieve a sealed connection between the two, and the valve cores of the first top-opening valve 11 and the second top-opening valve 22 contact each other and push open, and the first top-opening valve 11 and the second top-opening valve 22 are connected. Figure 5 As shown, there is no water in the kettle body 1, or the water level is not enough to float the float 12 until the second part / component 25 is separated from the first part / component 14, and the second part / component 25 is adsorbed on the base 2 under the attraction between the second part / component 25 and the first part / component 14, the second end of the lever 24 is in a high position, and the first end is in a low position. The valve core 232 of the mechanical valve 23 is in a low position or drops to a low position under the action of the magnet 243 at the first end, the valve core 232 opens the pressure relief hole 235, the mechanical valve 23 is opened, and the water inlet pipeline 21 is connected, and water can enter the kettle body 1 through the water inlet pipeline; as shown in FIG. Figure 8 As shown, as the water level in the kettle body 1 rises, the float 12 drives the first part / component 14 to float up under the action of buoyancy, thereby separating from the second part / component 25. When the water level in the kettle body 1 rises to the point where the attraction between the first part / component 14 and the second part / component 25 is insufficient to allow the second part / component 25 to be adsorbed on the base 2, the second part / component 25 detaches from the base 2. Under the action of the lever resetting element 242, the second end of the lever 24 drops to a low position, and the first end rises to a high position. The magnet 243 at the first end drives the valve core 232 of the mechanical valve 23 to rise. At the same time, under the action of the resetting element 233, the valve core 232 moves up to the valve core 232 to block the pressure relief hole 235, the mechanical valve 23 is closed, the water inlet pipe 21 is cut off, and water stops flowing into the kettle body 1.
