Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The thermostat of the electric kettle provided by the embodiment of the present invention includes a thermostat main body 1, a mounting plate 2 and an anti-reset assembly. The transmission part 4 on the main body 1 of the controller and in contact with the movable block 3, the compression spring 5 arranged on one side of the transmission part 4 and the anti-return stopper 6 connected with the transmission part 4, the anti-reset stopper 6 acts on the ceramic rod The electrode reed 8 below the 7, the installation end of the transmission part 4 and the anti-reset block 6 is provided with a steel spring.

In the heated state, the movable block 3 is jacked up, driving the transmission part 4 to move, thereby driving the anti-return block 6 to move forward, and then exerting a certain pressure on the steel spring, so that the front end of the anti-reset block 6 is covered with an electrode reed 8 Hold up, creating a forward trend. When the temperature of the bimetal sheet of the thermostat reaches the preset value, the bimetal sheet bends and squeezes the ceramic rod 7 downward, and the ceramic rod 7 pushes the reed 8 with electrodes downward, so that the circuit is disconnected and prevents from drying out. role. When the electrode-bearing reed 8 moves down, the anti-reset stopper 6 moves forward under the action of the steel spring and is stuck on the electrode-bearing reed 8, thereby preventing the ceramic rod 7 from resetting when the bimetal returns to its curvature. As a result, the electrode reed 8 is automatically connected to the circuit to continue heating, thereby avoiding the risk of cycle dry heating, and making the electric kettle more safe to use.

The movable block 3 includes an upper fixed column 31 , a lower fixed column and a top plate 32 , specifically, the lower fixed column is installed on the thermostat main body 1 , and the movable block 3 is in contact with the top plate 32 . When the coupling part of the coupler is connected, the lower fixed column is lifted up, which drives the movable block 3 to move upward as a whole, and the top plate 32 drives the transmission part 4 to move obliquely upward.

The anti-reset stopper 6 is provided with a slot, and the transmission member 4 is provided with a fixed block, which is installed in cooperation with the slot and slides in the slot, so that the two can be connected with the chute. In order to facilitate the relative movement of the two under the action of the steel spring, the mutual movement can be realized more stably.

In order to simplify the structure of the thermostat, the water temperature probe 9 can be integrated with the thermostat main body 1 . Specifically, the water temperature probe 9 can be installed on the mounting plate 2 . Preferably, the water temperature probe 9 is screwed or riveted on the mounting plate 2 . Of course, it is also feasible to choose other installation methods, which are not limited in this article. The two ends of the power supply of the water temperature probe can be respectively connected to the terminal 10 of the copper ring, as shown in the figure.

In the temperature controller of the electric kettle provided by the embodiment of the present invention, when the coupling part of the coupler is connected, the movable block 3 is lifted up, driving the transmission part 4 to move obliquely upward, and when the transmission part 4 moves forward, it will drive the anti-reset gear Block 6 moves forward, can produce a pressure to steel spring, and anti-return block 6 front ends are withstood by band electrode reed 8, produces a forward trend. When the temperature of the bimetal sheet of the thermostat reaches the preset value, the bimetal sheet bends and squeezes the ceramic rod 7 downward, and the ceramic rod 7 pushes the reed 8 with electrodes downward, so that the circuit is disconnected and prevents from drying out. When the electrode reed 8 moves down, the anti-reset block 6 moves forward under the action of the steel spring, and gets stuck on the electrode reed 8, preventing the ceramic The resetting of the rod 7 causes the electrode reed 8 to automatically switch on the circuit and continue heating, thereby avoiding the risk of cycle dry heating. When the coupler connection part is disconnected, the electric kettle is powered off, the movable block 3 has no upward pressure, and the transmission member 4 presses the movable block 3 downward under the action of the compression spring 5, so that the movable block 3 is reset, and the anti-reset stopper 6 reset, with electrode reed 8 reset. To sum up, the thermostat well avoids the continuous heating of the electric kettle caused by the automatic reset of the anti-dry structure, and improves the safety of use.
