Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of household appliances, and in particular to an electric kettle. Background Art
[0002] As a household water-boiling appliance, electric kettles are popular among many users because of their high water-boiling efficiency and ease of use.
[0003] When boiling water in an electric kettle, the amount of water inside the kettle must not exceed the capacity of its highest water level, otherwise water overflow or splashing will occur after the water boils. When filling water in existing electric kettles, since most water inlets are located relatively low, it is difficult for the user to accurately judge the water level in the electric kettle through the water level indicator on the electric kettle, which can easily cause excessive water intake, thereby easily causing the danger of overflow or splashing. Summary of the invention

[0005] In order to achieve the above-mentioned object, the present invention provides an electric kettle, comprising a kettle body, a handle, a mechanical sensor, a prompt element and a controller. The kettle body is used to hold water; the handle is arranged on the kettle body; the mechanical sensor is arranged on the kettle body or the handle, and is used to detect the force of the handle relative to the kettle body in a first direction; the prompt element is arranged on the kettle body or the handle, and is used to send a prompt signal indicating that there is too much water in the kettle body; the controller is electrically connected to the mechanical sensor and the prompt element, and is used to receive mechanical data detected by the mechanical sensor, and compare the mechanical data with a predetermined value, and if the mechanical data is greater than the predetermined value, the prompt element is controlled to send a prompt signal.
[0006] By applying the technical solution of the present invention, when the electric kettle receives water, the user holds the handle and pours water into the kettle body. As the amount of water in the kettle body increases, the force between the kettle body and the handle will become greater and greater. The amount of water in the kettle body can be inferred by detecting the force of the handle relative to the kettle body in a first direction through a mechanical sensor, and then receiving the mechanical data detected by the mechanical sensor through a controller.

In this way, the user can accurately judge the amount of water in the kettle body and avoid the danger of overflow or splashing due to excessive water in the kettle body.
[0007] Furthermore, the electric kettle also includes an angle sensor, which is arranged on the kettle body or the handle and is electrically connected to the controller. The angle sensor is used to detect the inclination angle of the kettle body relative to the vertical plane. The controller is used to receive angle data detected by the angle sensor and calculate the weight of the water in the kettle body through the angle data and mechanical data.
[0008] Furthermore, the handle is slidably arranged on the kettle body, and the mechanical sensor is located above the handle on the kettle body. The handle slides upward in a hand-carrying state to trigger the mechanical sensor.
[0009] Furthermore, the electric kettle also includes a limit baffle, which is arranged on the kettle body and is located below the handle on the kettle body. When the handle is not in the hand-held state, the handle slides onto the limit baffle and abuts against the limit baffle.
[0010] Furthermore, the mechanical sensor is a pressure sensor.

[0029] Figure 1 and Figure 2 An embodiment of an electric kettle of the present invention is shown, the electric kettle comprises a kettle body 10 and a handle 20, the kettle body 10 is used to hold water, and the handle 20 is arranged on the kettle body 10. The electric kettle also comprises a mechanical sensor 30, a prompt element 40 and a controller 50, the mechanical sensor 30 is arranged on the kettle body 10 for detecting the force of the handle 20 relative to the kettle body 10 in a first direction. The prompt element 40 is arranged on the handle 20 for issuing a prompt signal indicating that there is too much water in the kettle body 10. The controller 50 is electrically connected to the mechanical sensor 30 and the prompt element 40, and is used to receive the mechanical data detected by the mechanical sensor 30, and compare the mechanical data with a predetermined value. If the mechanical data is greater than the predetermined value, the prompt element 40 is controlled to issue a prompt signal.
[0030] By applying the technical solution of the present invention, when the electric kettle receives water, the user holds the handle 20 and pours water into the kettle body 10. As the amount of water in the kettle body 10 increases, the force between the kettle body 10 and the handle 20 becomes greater and greater. The force of the handle 20 relative to the kettle body 10 in the first direction is detected by the mechanical sensor 30, and then the controller 50 receives the mechanical data detected by the mechanical sensor 30, so that the amount of water in the kettle body 10 can be inferred. When the mechanical data received by the controller 50 is greater than a predetermined value, it means that the amount of water in the kettle body 10 has reached the predetermined value, and the controller 50 controls the prompt element 40 to send a prompt signal to prompt the user to stop pouring water into the kettle body 10. In this way, the user can accurately judge the amount of water in the kettle body 10, avoiding the danger of overflow or splashing due to excessive water in the kettle body 10.
[0031] In the technical solution of the present invention, it is feasible to set the controller 50 on the kettle body 10 or the handle 20, as long as the controller 50 can receive the mechanical data detected by the mechanical sensor 30 and then control the prompt element 40. As an optional implementation, the controller 50 can also be set on the heating base of the electric kettle, and the controller 50 can be electrically connected to the mechanical sensor 30 and the prompt element 40 through wireless communication.
[0032] As an optional implementation, it is also feasible to arrange the mechanical sensor 30 on the handle 20 to detect the force of the handle 20 relative to the kettle body 10 in the first direction.
[0033] As a preferred embodiment, Figure 1 and Figure 2 As shown, the electric kettle further includes an angle sensor 60, which is disposed on the handle 20 and is electrically connected to the controller 50. The angle sensor 60 is used to detect the inclination angle of the kettle body 10 relative to the vertical plane, and the controller 50 is used to receive the angle data detected by the angle sensor 60, and calculate the weight of the water in the kettle body 10 through the angle data and the mechanical data.
[0034] In some cases, when the electric kettle is receiving water, the kettle body 10 will be tilted relative to the vertical plane. If only the mechanical sensor 30 is used to detect the force of the handle 20 relative to the kettle body 10 in the first direction, the weight of the water in the kettle body 10 finally calculated by the controller 50 will not be accurate enough. By measuring the inclination angle of the kettle body 10 relative to the vertical plane through the angle sensor 60, and then detecting the force of the handle 20 relative to the kettle body 10 in the first direction through the mechanical sensor 30, the controller 50 can calculate the weight of the water in the kettle body 10 more accurately through mechanical analysis. Furthermore, by controlling the prompt element 40 to send a prompt signal through the controller 50, the user can be prompted to stop filling the kettle body 10 with water, so that the user can accurately judge the amount of water in the kettle body 10 and avoid the danger of overflow or splashing due to excessive water in the kettle body 10.
[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the handle 20 is slidably disposed on the kettle body 10, and the mechanical sensor 30 is located above the handle 20 on the kettle body 10. When the handle 20 slides upward in the hand-carrying state, the mechanical sensor 30 is triggered. In this way, the mechanical sensor 30 can accurately measure the force of the handle 20 relative to the kettle body 10 in the sliding direction thereof.
[0036] As an optional implementation, Figure 1 As shown, the electric kettle further includes a limit baffle 80, which is arranged on the kettle body 10, and the limit baffle 80 is located below the handle 20 on the kettle body 10. When the handle 20 is not in the hand-held state, the handle 20 slides onto the limit baffle 80 and abuts against the limit baffle 80, and the limit baffle 80 plays the role of limiting the handle 20.
[0037] like Figure 5 As shown, as an optional embodiment, a T-slot is provided on the handle 20, and a T-shaped slider matched with the T-slot is provided on the kettle body 10. Through the matching structure of the T-slot and the T-shaped slider, the handle 20 can slide relative to the kettle body 10, and the handle 20 can also be confined on the kettle body 10.
[0038] like Figure 3 and Figure 4In this embodiment, the mechanical sensor 30 includes a spring 31 and a potentiometer 32.

The potentiometer 32 includes a resistor 321 and a brush 322. The brush 322 is drivingly connected to the spring 31, and the resistor 321 is connected to the controller 50. When in use, when the handle 20 moves relative to the kettle body 10 to press the spring 31, the handle 20 will drive the spring 31 to compress, the spring 31 drives the brush 322 to move, and then the brush 322 changes the resistance value on the resistor 321. By establishing an empirical formula between the resistance value of the resistor 321 and the compression amount of the spring 31, the force of the handle 20 pressing the spring 31 can be obtained, and then the force of the handle 20 relative to the kettle body 10 in the first direction can be detected.
[0039] like Figure 4 As shown in FIG. 1 , by measuring the force of the handle 20 pressing against the spring 31, and then calculating the inclination angle of the kettle body 10 relative to the vertical plane through the angle sensor 60, the weight of the kettle body 10 and the water inside it can be calculated through mechanics. That is, the force of the handle 20 pressing against the spring 31 is F, and the inclination angle of the kettle body 10 relative to the vertical plane is The weight of the kettle body 10 and the water inside it is G. When the formula is satisfied When the water level reaches the maximum, the water level has reached the maximum. Spend, Through programming, As the judgment condition of the maximum water volume, when The controller 50 controls the prompt element 40 to give a corresponding prompt that the surface water is full.
[0040] As a more preferred embodiment, the mechanical sensor 30 is a pressure sensor, that is, the pressure of the handle 20 relative to the kettle body 10 in the first direction can be measured by the mechanical sensor 30. The use of a pressure sensor can make the structure of the entire electric kettle more compact.

Usually, the heating base of the electric kettle is provided with a power line for power supply, while the kettle body 10 is not connected with a power line. An independent battery 70 is arranged on the kettle body 10 to provide power to the mechanical sensor 30, the angle sensor 60 and the prompt element 40, which can make it easier to use the kettle body 10 without the power line.
[0042] As an optional implementation, it is also feasible to arrange the battery 70 on the handle 20 .
[0043] As a preferred embodiment, the prompt element 40 is a vibration motor disposed on the handle 20. When the mechanical data received by the controller 50 is greater than a predetermined value, the controller 50 controls the vibration motor to vibrate to remind the user to stop pouring water into the kettle body 10.
[0044] As other optional embodiments, the prompt element 40 can be a speaker, or a lamp, or a combination of the speaker and the lamp. Sound and light can also play a good role in reminding the user. As an optional embodiment, the speaker and / or the lamp can be arranged on the kettle body 10. As another optional embodiment, the speaker and / or the lamp can be arranged on the handle 20.
