[0103] Figure 1 A schematic diagram of the structure of the electric kettle provided in the embodiment of the present application is shown in FIG. Figure 1As shown, an embodiment of the present application provides an electric kettle 100, including a kettle cover 1, a kettle body 2, a bottom cover 3 and a base 4, a handle 5 is arranged on the kettle body 2, and the kettle body 2 is used to hold liquid.

[0104] Figure 2 This is a main cross-sectional view of the structure of the electric kettle in one state provided by an embodiment of the present application. Figure 3 A main cross-sectional view of the structure of the electric kettle in another state provided in an embodiment of the present application.

[0105] like Figure 2 and Figure 3 As shown, the handle 5 has a handle pipe 51 , through which water can be introduced into the interior of the kettle body 2 .

[0106] The electric kettle 100 may further include a heating plate 6, which is connected to the bottom of the kettle body 2 and is used to heat the water in the kettle body 2. The bottom cover 3 is connected to the kettle body 2, and a receiving cavity is formed between the bottom cover 3 and the heating plate 6. A connecting pipe 30 is provided in the receiving cavity, and the connecting pipe 30 can be connected to the handle pipeline 51, so that external water enters the handle pipeline 51 through the connecting pipe 30, and then enters the kettle body 2.

[0107] The heating plate 6 may be provided with a temperature sensor 7 to sense the water temperature in the kettle body 2 and control the heating plate 6 to start or stop heating according to the water temperature.

[0108] The electric kettle 100 may further include a first connector 10 and a second connector 20 , wherein the first connector 10 is connected to the bottom cover 3 , and the second connector 20 is connected to the base 4 . The first connector 10 and the second connector 20 are connected to connect the bottom cover 3 to the base 4 .

[0109] The first connecting member 17 may be provided with a first pipeline 101, the second connecting member 20 may be provided with a second pipeline 201, the first pipeline 101 is connected to the connecting pipe 30, the second pipeline 201 is connected to the first pipeline 101, and is connected to the water pump 8. The water pump 8 is provided in the base 4, and is used to pump external water into the kettle body 2.

[0110] In this way, external water can enter the kettle body 2 through the water pump 8 , the second pipeline 201 , the first pipeline 101 , the connecting pipe 30 and the handle pipeline 51 .

[0111] Reference Figure 2 and Figure 3 The electric kettle 100 provided in the embodiment of the present application may further include a control component 9 , which may include a control panel 91 and a probe 92 .

[0112] The control board 91 is used to store the control program, and the probe 92 is arranged in the kettle body 2 in a liftable manner.

[0113] The electric kettle 100 provided in the embodiment of the present application also includes the water replenishment control device provided in any embodiment of the present application, such as Fig.11 As shown, the water replenishment control device may include a calculation module 200 , a judgment module 300 and a control module 400 .

[0114] The calculation module 200 is used to calculate the real-time liquid level height in the electric kettle 100 according to the rise and fall of the probe 92 .

[0115] By calculating the real-time liquid level height in the electric kettle 100, the user can set the water level of his or her preference according to personalized needs. If the real-time liquid level height is lower than the water level, the electric kettle 100 can start automatic water replenishment, thereby improving the user experience.

[0116] Figure 4 This is a state diagram of the probe in the electric kettle provided in an embodiment of the present application when the electric kettle has a first liquid level line. Figure 5 This is a state diagram of the probe in the electric kettle provided in an embodiment of the present application when the electric kettle has a second liquid level line. Figure 6 This is a state diagram of the probe in the electric kettle provided in an embodiment of the present application when the electric kettle has a third liquid level line.

[0117] like Figures 4 to 6 As shown, in a specific embodiment, the probe 92 includes a support portion 921, a first electrode 922, and a second electrode 923. The first electrode 922 and the second electrode 923 are both connected to the support portion 921, and when the first electrode 922 and the second electrode 923 are both below the liquid surface, the first electrode 922 and the second electrode 923 can be connected, and when at least one of the first electrode 922 and the second electrode 923 is above the liquid surface, the first electrode 922 and the second electrode 923 can be disconnected.

[0118] Reference Figure 4 When the electric kettle 100 has the first liquid level line A1, the first electrode 922 and the second electrode 923 are both located above the first liquid level line A1, and at this time, the first electrode 922 and the second electrode 923 are not conductive.

[0119] Reference Figure 5 When the electric kettle 100 has the second liquid level line A2, the first electrode 922 is higher than the second liquid level line A2, and the second electrode 923 is lower than the second liquid level line A2. At this time, the first electrode 922 and the second electrode 923 are not conductive.

[0120] Reference Figure 6 When the electric kettle 100 has the third liquid level line A3, the first electrode 922 and the second electrode 923 are both lower than the third liquid level line A3, and at this time, the first electrode 922 and the second electrode 923 are conductive.

[0121] If the probe 92 is located at the highest position, during the water replenishment process, if it is detected that the first electrode 922 and the second electrode 923 are conducting, it can be determined that the water level after the water replenishment has reached the preset water level.

[0122] When it is necessary to detect the liquid level in real time, the control probe 92 is moved from high to low, and when it is detected that the first electrode 922 and the second electrode 923 are conducting, the real-time liquid level height can be calculated.

[0123] In a specific implementation, along the height direction of the electric kettle 100, the first electrode 922 is higher than the second electrode 923. In this embodiment, the first electrode 922 and the second electrode 923 are set at different heights, so that the first electrode 922 located at a higher position can achieve electrode conduction only when it is submerged below the liquid level. Even if the water surface is not stable, conduction can only be detected when a single electrode is submerged, thereby making the measurement result more accurate.

[0124] Reference Figure 2 and Figure 3 In a specific embodiment, the electric kettle 100 may further include a lifting rod 93 and a driving component. The first end of the lifting rod 93 is connected to the output end of the driving component, and the second end of the lifting rod 93 is connected to the probe 92 for driving the probe 92 to rise and fall.

[0125] Figure 2 The lifting rod 93 is in the state of descending to the lowest point. Figure 3 This is the state where the lifting rod 93 rises to the highest point.

[0126] In a specific embodiment, the driving component also includes a motor 96 and a reel 95 , wherein the motor 96 is used to provide driving force, the input end of the reel 95 is connected to the output end of the motor 96 , and the output end of the reel 95 is connected to the first end of the lifting rod 93 .

[0127] By providing the motor 96, the motor 96 drives the lifting rod 93 through the reel 95, so that a smoother lifting movement can be achieved.

[0128] In a specific embodiment, the electric kettle 100 further includes a heating plate 6 disposed at the bottom of the electric kettle 100 , and the lifting rod 93 is sealedly connected to the heating plate 6 via a sealing ring 94 .

[0129] By providing the sealing ring 94 , good sealing of the kettle body 2 can be achieved, thereby preventing water in the kettle body 2 from leaking into the bottom cover 3 .

[0130] Figure 7 A flow chart of a water replenishment control method provided in an embodiment of the present application, such as Figure 7 As shown, the embodiment of the present application also provides a water replenishment control method, including:

[0131] S101, calculating the real-time liquid level in the electric kettle 100.

[0132] S102, determining whether the real-time liquid level in the electric kettle 100 is lower than a preset liquid level; if yes, proceeding to S103.

[0133] In this step, the preset liquid level height can be a water level height set by the user according to personal preference, and different users have different requirements for what level of water to add. In the embodiment of the present application, the user can set the water level, that is, the preset liquid level height. After the user pours water into the electric kettle 100, when the liquid level in the electric kettle 100 is lower than the preset liquid level height, automatic water replenishment can be started.

[0134] S103, according to the real-time liquid level, controlling the water pump 8 of the electric kettle 100 to operate so as to replenish water into the electric kettle 100.

[0135] The water replenishment control method provided in the present application calculates the real-time liquid level in the electric kettle 100. If the real-time liquid level is lower than the preset liquid level, the water pump 8 is started to replenish water. By the user personalizing the preset liquid level, the water replenishment start time of the electric kettle 100 is more flexible, which improves the user experience.

[0136] In a specific implementation, if the judgment result in step S102 is no, then proceed to S104.

[0137] S104, enter waiting mode.

[0138] When the real-time liquid level in the electric kettle 100 is not lower than the preset liquid level, the kettle enters a waiting state, waiting for the user to pour water for use.

[0140] S201, controlling the probe 92 in the electric kettle 100 to descend from a first height to a second height; wherein the first height is higher than the second height.

[0141] In the embodiment of the present application, the electric kettle 100 may be provided with only one liftable probe 92, and the water level is sensed by lifting and lowering the probe 92, so as to calculate the real-time liquid level height. The first height may be the highest height that the probe 92 can reach in the electric kettle 100, and the second height is lower than the real-time liquid level and close to the height when the first electrode 922 and the second electrode 923 are turned on, and the second height is lower than the first height.

[0142] S202, determine whether the first electrode 922 and the second electrode 923 of the probe 92 are conductive; if so, proceed to S203.

[0143] When the probe 92 is dropped from the first height to the second height, if both the first electrode 922 and the third electrode 923 are submerged below the liquid surface, conduction will occur. If both the first electrode 922 and the third electrode 923 are above the liquid surface, or one of them is above the liquid surface, conduction will not occur.

[0144] S203, controlling the water pump 8 of the electric kettle 100 to stop working.

[0145] When the first electrode 922 and the second electrode 923 are connected, the water pump 8 stops, and the current real-time liquid level height can be calculated.

[0146] S204, calculating the real-time liquid level in the electric kettle 100 according to the height difference of the probe 92 falling.

[0147] In this step, since the probe 92 is dropped from the highest first height to the second height, the real-time liquid level can be obtained based on the relationship between the liquid level when the probe 92 is at the first height and the height difference when it is dropped.

[0148] S205, determining whether the real-time liquid level in the electric kettle 100 is lower than a preset liquid level; if yes, proceeding to S206.

[0149] S206, controlling the water pump 8 of the electric kettle 100 to operate according to the real-time liquid level height to replenish water to the electric kettle 100.

[0152] In this embodiment, the lifting and lowering movement of the probe 92 may be driven by a motor 96 .

[0153] S302, determine whether the first electrode 922 and the second electrode 923 of the probe 92 are conductive; if so, proceed to S303.

[0154] When the probe 92 is dropped from the first height to the second height, if both the first electrode 922 and the third electrode 923 are submerged below the liquid surface, conduction will occur. If both the first electrode 922 and the third electrode 923 are above the liquid surface, or one of them is above the liquid surface, conduction will not occur.

[0155] S303, controlling the water pump 8 of the electric kettle 100 to stop working.

[0156] When the first electrode 922 and the second electrode 923 are connected, the water pump 8 stops, and the current real-time liquid level height can be calculated.

[0157] S304, calculating the real-time liquid level in the electric kettle 100 according to the height difference of the probe 92 falling.

[0158] In this step, since the probe 92 is dropped from the highest first height to the second height, the real-time liquid level can be obtained based on the relationship between the liquid level when the probe 92 is at the first height and the height difference when it is dropped.

[0159] S305, determining whether the real-time liquid level in the electric kettle 100 is lower than the preset liquid level; if yes, proceeding to S306.

[0160] S306, controlling the water pump 8 of the electric kettle 100 to operate according to the real-time liquid level height to replenish water to the electric kettle 100.

[0161] Fig.10 A flow chart of another water replenishment control method provided in an embodiment of the present application, such as Fig.10 As shown, in Fig.10 In the illustrated embodiment, the method includes:

[0162] S401, controlling the motor 96 to drive the probe 92, so that the probe 92 descends from a first height to a second height.

[0163] In the embodiment of the present application, the probe 92 can be driven to move up and down by the motor 96. After the electric kettle 100 is turned on, the motor 96 can be used to first drive the probe 92 to rise from the lowest point to the highest point, that is, to the first height. Since the lowest point and the highest point of the probe 92 in the electric kettle 100 are pre-designed, the height that the probe 92 can rise per rotation of the motor 96 can be obtained based on this height difference. Then, the motor 96 drives the probe 92 to drop the probe 92 from the first height to the second height.

[0164] S402, determining whether the first electrode 922 and the second electrode 923 of the probe 92 are conducting; if so, proceeding to S403.

[0165] When the probe 92 is dropped from the first height to the second height, if both the first electrode 922 and the third electrode 923 are submerged below the liquid surface, conduction will occur. If both the first electrode 922 and the third electrode 923 are above the liquid surface, or one of them is above the liquid surface, conduction will not occur.

[0166] S403, controlling the water pump 8 of the electric kettle 100 to stop working.

[0167] When the first electrode 922 and the second electrode 923 are connected, the water pump 8 stops, and the current real-time liquid level height can be calculated.

[0168] S404, calculating the real-time liquid level in the electric kettle 100 according to the number of revolutions of the motor 96.

[0169] In this step, since the probe 92 is dropped from the highest first height to the second height, the real-time liquid level can be obtained based on the relationship between the liquid level when the probe 92 is at the first height and the height difference when it is dropped.

[0170] Specifically, the real-time liquid level height can be obtained by the following formula:

[0171] H = L - (L / Q) × Qn;

[0172] Among them, H is the real-time liquid level height; L is the height value of the first height; Q is the number of revolutions of the motor when the probe 92 is lowered from the highest point to the lowest point; Qn is the number of revolutions of the motor when the probe 92 is lowered from the first height (which can be the highest point) to the second height.

[0176] S501, controlling the probe 92 in the electric kettle 100 to be located at a first height.

[0177] In this step, the first height may be the highest point that the probe 92 can reach in the electric kettle 100 .

[0178] S502, controlling the water pump 8 to operate so as to replenish water into the electric kettle 1.

[0179] S503, determining whether the first electrode 922 and the second electrode 923 of the probe 92 are conductive; if so, proceeding to step S504.

[0180] S504, control the water pump 8 to stop working.

[0181] In this step, since the first height is the height of the higher water level in the electric kettle 100, it can be set that when the water level reaches the first height, it is confirmed that the water replenishment is in place. At this time, the water pump 8 can be controlled to stop working and wait for the user to lift the kettle to pour water.

[0182] If the water level in the electric kettle 100 drops after the user pours water from the kettle, the real-time liquid level height can be calculated to determine whether water replenishment is needed based on the real-time liquid level height.

[0183] S505, controlling the probe 92 in the electric kettle 100 to descend from the first height to the second height.

[0184] S506, determining whether the first electrode 922 and the second electrode 923 of the probe 92 are conducting; if so, proceeding to S507.

[0185] When the probe 92 is dropped from the first height to the second height, if both the first electrode 922 and the third electrode 923 are submerged below the liquid surface, conduction will occur. If both the first electrode 922 and the third electrode 923 are above the liquid surface, or one of them is above the liquid surface, conduction will not occur.

[0186] S507, controlling the water pump 8 of the electric kettle 100 to stop working.

[0187] When the first electrode 922 and the second electrode 923 are connected, the water pump 8 stops, and the current real-time liquid level height can be calculated.

[0188] S508, calculating the real-time liquid level in the electric kettle 100 according to the height difference of the probe 92 falling.

[0189] In this step, since the probe 92 is dropped from the highest first height to the second height, the real-time liquid level can be obtained based on the relationship between the liquid level when the probe 92 is at the first height and the height difference when it is dropped.

[0190] S509, determine whether the real-time liquid level in the electric kettle 100 is lower than the preset liquid level; if yes, proceed to S510.

[0191] S510, controlling the water pump 8 of the electric kettle 100 to operate according to the real-time liquid level height to replenish water to the electric kettle 100.

[0192] Fig.12The structural block diagram of the water replenishment control device provided in the embodiment of the present application is as follows: Fig.12 As shown, the water replenishment control device provided in the embodiment of the present application includes: a calculation module 200, a judgment module 300 and a control module 400.

[0193] Among them, the calculation module 200 is used to calculate the real-time liquid level height in the electric kettle 100; the judgment module 300 is used to judge whether the real-time liquid level height in the electric kettle 100 is lower than the preset liquid level height; the control module 400 is used to control the water pump 8 of the electric kettle 100 to work according to the real-time liquid level height when the judgment result of the judgment module 300 is yes, so as to replenish water to the electric kettle 100.

[0194] The water replenishment control device provided by the present application calculates the real-time liquid level in the electric kettle by setting a calculation module 200. If the judgment module 300 judges that the real-time liquid level is lower than the preset liquid level, the control module 300 starts the water pump to replenish water. By the user personalizing the preset liquid level, the water replenishment start time of the electric kettle is more flexible, which improves the user experience.

[0195] In a specific implementation, the control module 400 is further configured to control the electric kettle 100 to enter a waiting state when the determination result of the determination module 300 is no.

[0196] The embodiments of the present application also provide a non-temporary computer-readable storage medium on which a computer program is stored, wherein when the computer program is executed by a controller, any one of the methods provided in the embodiments of the present application is implemented.
