In the third state, as shown in fig. 8 and 9, the third contact 433 of the potentiometer 43 is engaged with the control component 44, the control component 44 controls the driving component 5 and the heating component 3 to be in the working state, and the blocking portion 421 blocks the flow passage 411c, at this time, the liquid in the heating component 3 is brought into the liquid outlet component 41 by the boiling water vapor only after being heated to boiling, and flows out from the first liquid outlet 411a, at this time, the user can receive the water close to the boiling point.

The three states of the control component 4 are realized by the matching of the first contact 431, the second contact 432 and the third contact 433 of the potentiometer 43 with the control component 44, so that the liquid heating container can discharge cold water, warm water and boiling water simultaneously, the structure is simple, the realization is convenient, and the heating power and the water outlet rate are adjustable.

In a possible embodiment, the control component 44 can also control a preset working time of the heating component 3 and/or the driving component 5, and when the preset working time is reached, the control component 44 can also control the heating component 3 and/or the driving component 5 to stop working.

In this embodiment, the control unit 44 sets the working time in advance, and after the preset working time is reached, the control unit 44 can automatically turn off the power supply of the heating unit 3 and/or the driving unit 5 to stop working, so that unmanned operation is conveniently realized, and the time of a user is saved. Meanwhile, the control part 44 can know the position of the blocking part 421 through the position of the potentiometer 43 and the opening size of the flow channel 411c, so that the water outlet time can be accurately controlled. When normal temperature water is discharged, the flow passage 411c is completely opened, the water discharge amount is large, the control component 44 can shorten the water discharge time, and the phenomenon of cup overflow caused by large water discharge amount per minute is prevented. When boiling water is discharged, the blocking part 421 blocks the flow passage 411c, the water turns over the blocking part 421 by the vapor pressure of the boiling water, the water discharge amount is small, and the control part 44 can prolong the water discharge time. When warm water is discharged, the control part 44 can properly adjust the length of the water discharge time according to the size of the opening flow passage 411c of the blocking part 421, so as to control the water discharge amount, thereby ensuring that the water discharge amount is consistent in each state.

In a possible embodiment, as shown in fig. 3, the housing 1 has a fourth cavity 11, the control part 44 and the potentiometer 43 are installed in the fourth cavity 11, the control part 44 is installed on the top wall of the liquid outlet part 41, a part of the operating part 42 protrudes outside the fourth cavity 11, the control part 44 is provided with a button 441, and a part of the button 441 protrudes outside the fourth cavity 11.

In this embodiment, the control component 44 and the potentiometer 43 are located in the fourth cavity 11, the control component 44 is installed on the top wall of the liquid outlet component 41, and the fourth cavity 11 is separated from the first cavity 411 of the liquid outlet component 41, so that the control component 44 and the potentiometer 43 are in a dry environment, thereby preventing the liquid in the first cavity 411 from splashing on the control component 44 and the potentiometer 43, causing danger, and ensuring the safety of the liquid heating container. The button 441 of the control part 44 protrudes outside the fourth cavity 11, so as to be convenient for the user to operate.

In addition, as shown in fig. 10, in order to ensure the safety of the liquid heating container, a first temperature controller 46 and a second temperature controller 47 are further designed, wherein the first temperature controller 46 is an automatic trip temperature controller, the second temperature controller 47 is a manual reset trip temperature controller, that is, the second temperature controller 47 must be manually intervened to recover to the working state, and the trip temperature of the second temperature controller is slightly higher than that of the first temperature controller 46. When the temperature of the heating element 3 exceeds the first kick temperature, the first temperature controller 46 will automatically open the circuit to prevent the heating element 3 from being burned dry. When the temperature of heating block 3 exceeded second snap-through temperature, second temperature controller 47 can automatic disconnection circuit, and can not automatic re-setting connect after the disconnection, must intervene artificially and could make heating block 3 rerun, this second temperature controller 47 is used for preventing that the temperature is less than behind the first snap-through temperature in heating block 3, but under the condition that the potential safety hazard was not eliminated, heating block 3 restarted and brought the potential safety hazard, further improved liquid heating container's safety in utilization.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
