Description

Technical Field

[0001] The invention relates to the technical field of household appliances, in particular to a kettle capable of preventing a kettle cover from falling off. Background Art

[0002] A kettle is a device for heating liquid, which usually includes a kettle body and a kettle lid which can be opened and closed on the kettle body. In order to facilitate the injection of the heated liquid into the kettle body, the kettle lid and the kettle body are mostly separated. The defect of the separated structure is that when the user holds the heated kettle to pour the liquid out, the kettle lid is easily separated from the kettle body, causing the high-temperature liquid in the kettle to splash out and scald the user, resulting in a safety accident.

[0003] In order to solve this problem, the existing solutions of kettles mainly include: setting a threaded screw-in structure between the kettle lid and the kettle body, setting a limiting structure between the kettle lid and the kettle body, and setting a permanent magnet on the kettle lid or the kettle body. Although the above method can avoid the kettle lid from being opened when pouring out the high-temperature liquid after heating, it also makes it inconvenient to open the kettle lid before injecting the liquid to be heated into the kettle body, which leads to poor user experience. Specifically, a kettle with a threaded screw-in structure requires the kettle lid to be rotated several times before the lid can be removed, a kettle with a limiting structure requires the angle of the kettle to be adjusted until the limiting structure is avoided before the lid can be removed, and a kettle with a permanent magnet requires the user to use a certain amount of force to pull open the lid. Summary of the invention

[0004] The purpose of the present invention is to provide a kettle which is more convenient to use and can prevent the kettle cover from falling off.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A kettle capable of preventing a kettle lid from falling off comprises a kettle body and a kettle lid which are separated from each other, wherein an electromagnetic device and a power supply device are arranged on one of the kettle body and the kettle lid, and the other is made of magnetic material; the power supply device is used to supply power to the electromagnetic device, and the electromagnetic device can absorb an object made of magnetic material after being energized.

[0008] In particular, the level detection device is electrically connected to the power supply device.

[0009] In particular, the level detection device is a tilt angle sensor.

[0010] In particular, a threshold value A is preset in the control device, and when the inclination angle α detected by the inclination angle sensor is greater than or equal to the threshold value A, the electromagnetic device is started.

[0011] In particular, the kettle further comprises a distance detection device electrically connected to the power supply device, wherein the distance detection device is configured to detect whether the kettle body is lifted; and the distance detection device is signal-connected to the control device.

[0012] In particular, the distance detection device is a displacement sensor.

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] Embodiment 1

[0022] This embodiment discloses a kettle that can prevent the lid from falling off. Figure 1As shown, the kettle comprises a kettle body 1 and a kettle cover 2 made of magnetic material, which are separated from each other. An electromagnetic device 3 and a power supply device 4 are arranged on the kettle body 1. The power supply device 4 is used to supply power to the electromagnetic device 3. After the electromagnetic device 3 is energized, it can absorb the object made of the magnetic material. Of course, the kettle cover 21 can also be provided with the electromagnetic device 3 and the power supply device 4, and the kettle body 1 is made of magnetic material.

[0023] The power supply and power failure of the power supply device 4 are used to control the start and stop of the electromagnetic device 3, so as to achieve close connection and separation between the kettle body 1 and the kettle cover 2. When the high-temperature liquid needs to be poured out after heating, the power supply device 4 supplies power to the electromagnetic device 3, and the electromagnetic device 3 starts and absorbs the kettle cover 2, ensuring that the kettle cover 2 will not be accidentally opened during the tilting of the kettle body 1, which is safer to use; when the liquid to be heated needs to be poured into the kettle body 1, the power supply device 4 does not work, and the electromagnetic device 3 is turned off. The user can easily remove the kettle cover 2 and pour the liquid to be heated into the kettle body 1 through the position of the kettle mouth, which is more convenient to use and does not require laborious rotation of the kettle cover 2 or strong pulling of the kettle cover 2. The overall structure of the kettle is simple and reasonable, and the manufacturing cost is low.

[0024] On the basis of the above structure, the kettle further comprises a horizontal detection device 5 and a control device, wherein the horizontal detection device 5 is preferably an inclination angle sensor. The horizontal detection device 5 is used to detect the inclination angle of the kettle body 1, and when the kettle body 1 is inclined beyond a certain angle, it is determined that high-temperature liquid is being poured out; the control device is respectively connected to the power supply device 4 and the horizontal detection device 5 by signal, and the horizontal detection device 5 sends the detected inclination angle value to the control device. If the control device determines that high-temperature liquid is currently being poured out according to the inclination angle value, the control device controls the power supply device 4 to supply power to the electromagnetic device 3, and the electromagnetic device 3 starts and adsorbs and fixes the kettle lid 2. The horizontal detection device 5 and the control device are respectively electrically connected to the power supply device 4, and the power supply device 4 supplies power to the horizontal detection device 5 and the control device respectively.

[0025] Regarding "the control device determines that the hot liquid is currently being poured out according to the tilt angle value", in order to avoid misjudgment, a threshold value A is preset in the control device, and the electromagnetic device 3 is activated when the tilt angle α detected by the tilt angle sensor is greater than or equal to the threshold value A. The value of the threshold value A needs to be determined according to the structure of the kettle body 1. When the tilt angle α detected by the tilt angle sensor is less than the threshold value A, the electromagnetic device 3 is turned off, so as to avoid the phenomenon that the user needs to pour the liquid to be heated into the kettle body 1 but cannot open the kettle lid 2 because the kettle body 1 is slightly tilted, which is more convenient to use.

[0026] On the basis of the above structure, the kettle further comprises a distance detection device 6 electrically connected to the power supply device 4, and the distance detection device 6 is preferably a displacement sensor. The distance detection device 6 can detect whether the kettle body 1 is lifted, and only when the kettle body 1 is lifted does it start to detect the tilt angle of the kettle body 1, and there is no need for the horizontal detection device 5 to be kept in working state continuously; the distance detection device 6 is connected to the control device signal, and when the distance detection device 6 determines that the kettle body 1 is lifted, it sends information to the control device, and the control device turns on the horizontal detection device 5 and starts to detect the tilt angle of the kettle body 1.

[0027] On the basis of the above structure, the kettle further includes a base 8 and a coupler 7 arranged on the base 8. The power supply device 4 can be charged by connecting with the coupler 7 or by wireless charging, etc., which is more convenient to use.

[0028] Embodiment 2

[0029] This embodiment discloses a kettle capable of preventing the lid from falling off, and its structure is basically the same as that of the first embodiment, except that there is no level detection device 5 and distance detection device 6, but a switch is provided on the handle 11 of the kettle body 1, and the switch signal is connected to the power supply device 4. When the user pours the high-temperature liquid out, he needs to hold the handle 11, and at this time, he can easily press the switch to make the power supply device 4 supply power to the electromagnetic device 3, and the electromagnetic device 3 absorbs the kettle lid 2 after being energized. It is easy to use, has a simpler structure, and has a longer service life.
