A first permanent magnet 17 is provided on the end thereof, and the valve pendulum 133 is installed in the water storage chamber 101 in a manner that it can rotate around the other end of the valve pendulum 133 and limit the left and right positions, so that the valve pendulum 133 closes or conducts the connection 1001 between the spout tube 14 and the water storage chamber 101, and a magnetic conductor 18 is provided on one side of the partition 16 facing the circuit device compartment 102 corresponding to one end of the valve pendulum 133, and the valve switch 132 is provided on the lower side of the magnetic conductor 18 in a manner that it can rotate and limit the left and right positions. On the other hand, a second permanent magnet 19 is provided on the valve switch 132 corresponding to the magnet 18, the polarities of the first permanent magnet 17 and the second permanent magnet 19 are opposite, one end of the valve switch 132 extends out of the circuit device compartment 102 and extends out of the kettle body 11, and by toggling the valve switch 132, the second permanent magnet 19 rotates with the valve switch 132 and moves away from or close to the magnet 18. In the initial state, the second permanent magnet 19 is close to the magnet 18.

[0014] Among them, the polarity of the first permanent magnet 17 and the second permanent magnet 19 is opposite, which means that the magnetic pole polarity of the end of the first permanent magnet 17 close to the second permanent magnet 19 is the same as the magnetic pole polarity of the end of the second permanent magnet 19 close to the first permanent magnet 17, then the magnetic pole polarity of the first permanent magnet 17 and the second permanent magnet 19 on the opposite sides is the same. In the initial state, the second permanent magnet 19 is close to the magnetizer 18, and the magnetizer 18 is affected by the magnetic field of the second permanent magnet 19, so that the magnetic pole polarity of the end of the magnetizer 18 close to the second permanent magnet 19 is opposite to the magnetic pole polarity of the end of the second permanent magnet 19 close to the magnetizer 18, then the end of the magnetizer 18 away from the second permanent magnet 19 is opposite to the magnetic pole polarity of the end of the second permanent magnet 19 close to the magnetizer 18. 8 has the same magnetic pole polarity. At this time, the end of the magnet 18 away from the second permanent magnet 19 has the same magnetic pole polarity as the end of the first permanent magnet 17 close to the second permanent magnet 19. According to the property that like-pole magnetic poles repel each other, the first permanent magnet 17 moves away from the magnet 18, thereby driving one end of the valve pendulum 133 to move away from the magnet 18. The valve pendulum 133 moves away from the connection 1001 between the spout tube 14 and the water storage chamber 101, so that the valve pendulum 133 connects the connection 1001 between the spout tube 14 and the water storage chamber 101. The spout tube 14 is connected to the water storage chamber 101, and the water in the water storage chamber 101 can flow out of the spout tube 14, so that the kettle can be used normally. The side sectional view of the overflow-proof kettle 10 in the initial state is shown in FIG. Figure 2 As shown, Figure 2 The direction of the double arrow M is the direction in which the first permanent magnet 17 moves away from the magnet 18 and one end of the valve pendulum 133 moves away from the magnet 18 according to the characteristic that like-pole magnetic poles repel each other. Figure 2 The single arrow in the figure indicates the direction of water flow. Figure 3The side cross-sectional view of the overflow-proof kettle 10 in the normal closed state is shown. The normal closed state refers to the state in which the valve switch 132 is toggled to close the connection 1001 between the spout tube 14 and the water storage chamber 101 when the kettle is placed normally. When the valve switch 132 is toggled, the second permanent magnet 19 rotates with the valve switch 132 and moves away from the magnet 18. The magnet 18 is not affected by the second permanent magnet 19, and the magnet 18 does not generate a repulsive force on the first permanent magnet 17. The magnetism of the magnet 18 gradually weakens as the valve switch 132 moves away. The valve oscillating portion 133 closes the connection between the spout tube 14 and the water storage chamber 101, and the connection between the spout tube 14 and the water storage chamber 101 is cut off. The water in the water storage chamber 101 cannot flow out of the spout tube 14, so as to prevent the water in the kettle from accidentally flowing out and avoid accidental injury to the user. The anti-overflow kettle 10 is provided with a partition 16 horizontally inside the kettle body 11, which divides the interior of the kettle body 11 into a circuit device compartment 102 and a water storage chamber 101 connected to the spout tube 14, and an anti-overflow device 13 is provided inside the kettle body 11, which includes a valve assembly 131 arranged in the water storage chamber 101 and a valve switch 132 arranged in the circuit device compartment 102, and the valve assembly 131 includes a valve pendulum 133 arranged corresponding to the connection 1001 between the spout tube 14 and the water storage chamber 101, one end of the valve pendulum 133 is arranged close to the partition 16 and a first permanent magnet 17 is provided on one end of the valve pendulum 133, and the valve pendulum 133 is installed in the water storage chamber 101 in a manner that it can rotate around the other end of the valve pendulum 133 and limit the left and right, so that the valve pendulum 133 can close or conduct the connection 1001 between the spout tube 14 and the water storage chamber 101, and the side of the partition 16 facing the circuit device compartment 102 corresponds to the valve pendulum 133 A magnet 18 is provided at one end, and a valve switch 132 is provided below the magnet 18 in a rotatable and left-right limited manner. A second permanent magnet 19 is provided on the valve switch 132 corresponding to the magnet 18. The polarities of the first permanent magnet 17 and the second permanent magnet 19 are opposite. Through the cooperation between the second permanent magnet 19, the magnet 18 and the first permanent magnet 17, the movement of the valve pendulum 133 is controlled by controlling the valve switch 132, thereby closing or opening the connection 1001 between the spout tube 14 and the water storage chamber 101, so that when the kettle is tilted toward the side where the spout tube 14 is provided, the valve switch 132 is toggled to cause the valve pendulum 133 to close the connection 1001 between the spout tube 14 and the water storage chamber 101, the connection between the spout tube 14 and the water storage chamber 101 is cut off, and the water in the water storage chamber 101 cannot flow out of the spout tube 14, so as to prevent the water in the kettle from accidentally flowing out and avoid accidental injury to the user.

[0015] Specifically, the valve switch 132 is provided on the side of the circuit device compartment 102 close to the spout tube 14, so as to ensure that when the kettle is tilted toward the side where the spout tube 14 is provided, the valve switch 132 is toggled so that the valve swing 133 closes the connection 1001 between the spout tube 14 and the water storage chamber 101. Figure 4 As shown, the dumping closed state refers to the state in which the valve switch 132 is toggled to close the connection 1001 between the spout tube 14 and the water storage chamber 101 when the kettle dumps. Figure 4 The direction of the middle arrow K is the direction of movement of the valve switch 132 when the kettle falls over, and the direction of the double arrow L is the direction of movement of the first permanent magnet 17 approaching the magnetizer 18 and the valve pendulum 133 approaching the connection 100 between the spout tube 14 and the water storage chamber 101. When the kettle falls over, especially when the kettle falls to the side where the spout tube 14 is provided, the valve switch 132 is toggled, and the second permanent magnet 19 rotates with the valve switch 132 and moves away from the magnetizer 18. The magnetizer 18 is not affected by the second permanent magnet 19, and the magnetizer 18 does not generate a repulsive force on the first permanent magnet 17. The magnetism of the magnetizer 18 gradually weakens and is lost as the valve switch 132 moves away. The first permanent magnet 17 is acted upon by gravity to move closer to the magnetizer 18. The valve body 133 moves, and as the distance from the magnet 18 shortens, it generates an adsorption force on the magnet 18, driving the valve swing 133 to approach the connection 1001 between the spout tube 14 and the water storage chamber 101, so that the valve swing 133 closes the connection 1001 between the spout tube 14 and the water storage chamber 101, and the connection between the spout tube 14 and the water storage chamber 101 is cut off. The water in the water storage chamber 101 cannot flow out of the spout tube 14, so as to prevent the water in the kettle from accidentally flowing out and avoid accidental injury to the user.

[0016] Specifically, in this embodiment, one end of the valve switch 132 is tilted from top to bottom and outward, and the kettle body 11 is provided with an avoidance opening 111 for one end of the valve switch 132 to pass through. In the initial state, one end of the valve switch 132 is close to the lower surface of the avoidance opening 111, so that when the kettle tilts toward the side of the spout tube 14, one end of the valve switch 132 is easily moved by the external environment such as the desktop and the ground, thereby automatically triggering the second permanent magnet 19 to rotate with the valve switch 132 and move away from the magnet 18, so that the first permanent magnet 17 drives the valve pendulum 133 to move close to the magnet 18 and close the connection 1001 between the spout tube 14 and the water storage chamber 101, thereby realizing the cutting off of the communication between the spout tube 14 and the water storage chamber 101. The kettle body 11 is provided with an escape opening 111 through which one end of the valve switch 132 extends. The slope of the valve switch 132 when the valve switch 132 is moved to approach the upper surface of the escape opening 111 is smaller than the slope of the valve switch 132 when the valve switch 132 is initially positioned to approach the lower surface of the escape opening 111. The other end of the valve switch 132 may be provided with a mounting position for the second permanent magnet 19.

[0017] Specifically, in this embodiment, the valve assembly 131 also includes a valve bracket 134 and a valve sealing ring 135.

The valve bracket 134 is provided on the side of the valve sealing ring 135 away from the spout tube 14. The valve bracket 134 has a through hole 1341 corresponding to the through opening 1351. The valve pendulum 133 is located on the side of the valve bracket 134 away from the valve sealing ring 135, and the other end of the valve pendulum 133 is rotatably connected to the upper end portion of the valve bracket 134 so that the valve pendulum 133 can cover the through opening 1351.

[0018] Specifically, in this embodiment, the valve sealing ring 135 extends outward from one side close to the spout tube 14 to form a connecting end 1352 embedded in the spout tube 14, and the connecting end 1352 is provided with a water outlet 1353 connected to the through port 1351, and the radial dimension of the water outlet 1353 is not less than the radial dimension of the through port 1351.

[0019] Specifically, the valve sealing ring 135 extends from one side away from the spout tube 14 to form a boss 1354, and the through-port 1351 passes through the boss 1354. The outer edge of the boss 1354 is provided with a groove for the edge of the through-hole 1341 to be clamped. The valve bracket 134 is fixed by setting the boss 1354 and the outer edge of the boss 1354 is provided with a groove to clamp the edge of the through-hole 1341, so that the valve bracket 134 is firmly connected to the valve sealing ring 135; the boss 1354 is penetrated by the through-port 1351, so that the valve pendulum 133 can better close the through-port 1351 by contacting with the end face of the boss 1354, thereby improving the sealing effect.

[0020] Specifically, in this embodiment, the valve support 134 includes a support plate 1342, which is disposed facing the valve sealing ring 135.

The end of the support plate 1342, which is adjacent to the partition 16, is bent 90 degrees to form a bottom plate that contacts the partition 16, thereby improving the stability of the valve support 134.

[0021] Specifically, an end portion of one end of the valve pendulum 133 forms a slot for placing the first permanent magnet 17 , and the valve assembly 131 further includes a valve pendulum cover 136 covering the slot.

[0022] Specifically, a snap-fit ​​structure is provided at one end of the valve pendulum 133 between the edge of the slot opening and the valve pendulum cover 136, so that the valve pendulum cover 136 is detachably connected to the end of one end of the valve pendulum 133 through the snap-fit ​​structure and covers the slot. Preferably, a groove is provided at one end of the valve pendulum 133 at the edge of the slot opening, and the valve pendulum cover 136 is provided with a protrusion corresponding to the groove. The protrusion is snap-fitted into the groove, so that the valve pendulum cover 136 is detachably connected to the end of one end of the valve pendulum 133 and covers the slot. Of course, in other embodiments, a protrusion is provided at one end of the valve pendulum 133 at the edge of the slot opening, and the valve pendulum cover 136 is provided with a groove corresponding to the protrusion.
