DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0028] Such as Figures 1 to 4As shown in the figure, an intelligent electric kettle provided in this embodiment includes a kettle body 1 and a base 2. A connector 21 is provided on the base 2. The base 2 is plugged into and electrically connected to a connector seat 11 provided at the bottom of the kettle body 1 through the connector 21. By the plug-in fit between the connector 21 and the connector seat 11, stable electric energy can be provided for the intelligent electric kettle to ensure its stable and normal operation. In order to enable the intelligent electric kettle to integrate multiple functions such as automatic water filling, boiling, precise constant temperature, and intelligent Internet control, making it easier and more convenient for users to operate and improving the user experience. Further, the intelligent electric kettle further includes a control circuit board 3, a water pumping component 4, a heating plate 5, a temperature sensor 6, and a water level sensor 7. The signal terminals of the water pumping component 4, the heating plate 5, the temperature sensor 6, and the water level sensor 7 are electrically connected to the signal terminals of the control circuit board 3 respectively. The temperature sensor 6 and the water level sensor 7 are respectively provided on the heating plate 5. The control circuit board 3 includes a temperature control module 31 and a water level control module 32. The temperature control module 31 is used to compare the real-time water temperature value detected by the temperature sensor 6 with the temperature threshold set by the temperature control module 31 to control the heating action of the heating plate 5. The water level control module 32 is used to compare the real-time water level value detected by the water level sensor 7 with the water replenishment water level threshold set by the water level control module 32 to control the water pumping action of the water pumping component 4. The temperature sensor 6 can detect the real-time water temperature in the kettle body 1 and transmit the temperature information to the control circuit board 3. The water level sensor 7 can detect the real-time water level in the kettle body 1 and transmit the water level information to the control circuit board 3. Among them, in order to maintain the constant temperature of the water in the kettle body 1, the user can preset the required temperature threshold through the temperature control module 31 according to the needs. When it is detected that the real-time water temperature is lower than the temperature threshold, the temperature control module 31 can control the heating plate 5 to heat the water so that the water temperature exceeds the set temperature, and stop heating until the water boils (or the water temperature reaches 100 °C). At the same time, in order to ensure that the amount of water below the lowest water level in the kettle body 1 can still meet the brewing requirements of a pot of tea, therefore, it is necessary to always keep the amount of water in the kettle body 1 sufficient. Based on this, the user can preset the required water replenishment water level threshold through the water level sensor 7 according to the brewing water volume requirement. When it is detected that the real-time water level value is lower than the water replenishment water level threshold, the water level sensor 7 can control the water pumping component 4 to automatically pump water so that the water level reaches the set height, realizing automatic water filling without frequently opening the lid to add water. The intelligent electric kettle of this application has a smaller floor area compared with the traditional electric kettle. Further, in the intelligent electric kettle of this embodiment, its water replenishment water level threshold is not lower than two-thirds of the height value of the kettle body 1, so as to ensure that the amount of water in the kettle body 1 is sufficient and can meet the brewing requirements of the user. Through the above process, the control circuit board 3 can, through the setting of the intelligent program, automatically inject water into the kettle, heat it and maintain it at an appropriate temperature. When a low water level is detected, it can automatically circulate water filling and boiling within a set time to ensure that there is sufficient and appropriately temperature water during the tea brewing process.Moreover, since the intelligent electric kettle of the present application detects the water temperature and water level in real time, it can perform the actions of boiling water and replenishing water in a timely manner without manual judgment, meeting the user's tea-making needs at any time and saving the waiting time for manual judgment of boiling water or adding water.

[0029] As a preferred embodiment, the MCU chip model of the control circuit board 3 is any one of TM55FE8275, MKE02Z16, and CM9M04X.

Specifically, the temperature threshold can be set to 80°C to 90°C to ensure that the water temperature meets the temperature requirements for making tea. Through the above process, when the water temperature is lower than the set temperature threshold, the heating plate 5 can be automatically started to heat and exceed the set temperature until the water boils (i.e., the water temperature reaches 100°C), ensuring that there is water with a suitable temperature during the tea-making process.

[0032] Preferably, when the real-time water level value detected by the water level sensor 7 is less than the water replenishment level threshold set by the water level control module 32, the water level control module 32 controls the water pumping component 4 to start pumping water until the real-time water level value reaches the water pumping level value set by the water level control module 32, and then controls the water pumping component 4 to stop pumping water; when the real-time water level value detected by the water level sensor 7 is greater than the water replenishment level threshold set by the water level control module 32, the water pumping component 4 is maintained in the standby state. Specifically, the water replenishment level threshold can be customized with a height value through the water level control module 32 according to the user's functional requirements, for example, set to be between one-half and two-thirds of the height value of the kettle body 1, to ensure that the remaining water volume in the kettle body 1 meets the water volume requirements for making tea. Through the above process, when the real-time water level value is lower than the set water replenishment level threshold, the water pumping component 4 can be started to automatically pump water and keep the water volume in the kettle body 1 at an appropriate water level height, ensuring that there is sufficient water volume during the tea-making process.

[0034] In order to ensure the reliability of the water pumping process of the intelligent electric kettle and avoid water leakage problems, further, the water outlet end of the water outlet pipe 43 is connected to the connection seat 11 through a water outlet valve 8.
