Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, and specifically relates to a kettle. Background Technology

[0002] An electric kettle is a small household appliance that uses electricity to boil water. Currently, most electric kettles use steam sensors to achieve the core component of "water boiling reminder and power off" to automatically shut off the power. In addition to the core automatic power off, some electric kettles also add the following prompts: sound prompts: some mid-to-high-end or smart kettles will emit a "beep" sound when the power is cut off to remind the user that the water has boiled; light indicators: the indicator light is always on when heating (usually red), and the indicator light goes off or turns into a keep-warm light (usually green / blue) after the water boils and the power is cut off. However, the above prompts are relatively traditional and cannot meet the requirements of younger users for creative home furnishings. Therefore, it is very important to obtain a kettle lid and kettle with creative design. Summary of the Invention

[0003] To solve at least one of the above-mentioned technical problems, in one aspect, the present invention provides a kettle lid, comprising: The lid body has a control cavity inside, and at least one indicator hole is provided on the cavity; At least one electromagnet is installed in the control cavity; At least one indicator, at least partially located outside the lid body, wherein the electromagnet extends or retracts upon receiving a control signal, and moves the indicator relative to the lid body through an indicator perforation.

[0004] A circuit board is fixed inside the control cavity, and a control module is mounted on the circuit board. The output of the control module is electrically connected to the electromagnet. The control module can be an existing control chip, etc., and the temperature sensor is electrically connected to the input of the control module.

[0005] In this invention, an extension is provided on the kettle lid body, and a power supply contact is fixed on the extension. The power supply contact is connected to the battery management module of the circuit board via a wire, converting the power supply of the electric kettle body into the voltage required by the circuit board to power the components on the circuit board. The power supply contact is connected to the power supply of the electric kettle body. Alternatively, the kettle lid body of this invention does not have a power supply contact, but a power supply battery is fixed in the control cavity, and the power supply battery powers the circuit board.

[0006] As a preferred embodiment, a horn is fixed on the lid body, and the output of the control module is electrically connected to the horn. When the temperature sensor receives a signal that the water is boiling, it sends the signal to the control module on the circuit board. The control module controls the horn to emit a sound to remind the user, and can also drive the electromagnet to control the indicator to move up and down to provide a reminder.

[0007] Electromagnets can be of two types. Type 1: The electromagnet is a push-pull type. The output end of the push-pull type electromagnet is fixedly connected to the indicator through a connecting post. That is, the connecting post passes through the indicator hole and connects to the indicator, causing the indicator to jump up and down.

[0008] Method 2: The electromagnet is a DC chuck electromagnet. The bottom of the indicator is connected to the indicator hole via a spring. A magnet is fixed to the bottom of the indicator. When the DC chuck electromagnet is energized, it generates magnetic force, which repels the magnet, causing the spring to compress and the indicator to move upward. When the power is off, the spring elastically expands and the indicator moves downward.

[0009] The kettle lid of this invention controls an electromagnet to move an indicator up and down when the water boils, providing a creative prompt and increasing the fun of using it.

[0010] On the other hand, the present invention provides a kettle, including an electric kettle body and the kettle lid, wherein a heating inner liner is fixed inside the electric kettle body, and the power supply of the electric kettle is connected to a heating wire through a first wire, the heating wire supplying power to the heating inner liner; a mating contact is fixed on the electric kettle body, and the power supply is electrically connected to the mating contact through a second wire, the mating contact being electrically connected to the power supply contact.

[0011] The main body of the electric kettle is shaped like a large duck, and the indicator is shaped like a small duck.

[0012] The shape of the present invention is not limited to the above-described shape; it can also be that the main body of the electric kettle is shaped like a moon and the indicator is shaped like a star.

[0013] Compared with existing technologies, the advantages of this invention are as follows: This invention uses an electromagnet to drive the dynamic displacement of the indicator, which differs from traditional buzzers / lights and meets the needs of young users for creative home furnishings. The novel and intuitive prompting method of this invention enhances the user experience; the combination of a horn and the mechanical movement of the indicator achieves multi-dimensional prompting through "sound and motion," avoiding the shortcomings of single prompting methods being easily overlooked. Multi-sensory collaborative prompting enhances interactive feedback; creative designs such as a large duck-shaped kettle body with a small duck indicator and a moon with stars enhance the added value of the product; the creative design of this invention combines practicality and decoration.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection claimed by the present invention, the present invention will be described in detail below with reference to certain specific embodiments. It should be noted that the following are merely some specific embodiments of the inventive concept, and the specific and direct descriptions of related structures are only for the purpose of facilitating understanding of the present invention; the specific features do not necessarily or directly limit the scope of the present invention.

[0017] Referring to the accompanying drawings, in one aspect, the present invention provides a kettle lid, comprising: The lid body 1 has a control cavity 102 inside, and at least one indicator hole 101 is provided on the cavity. The lid body 1 includes a top part 103 and a bottom part 104, which are fixed or snap-fit ​​connected and form the control cavity 102 when they are closed.

[0018] At least one electromagnet is installed in the control cavity 102; At least one indicator 3 is located at least partially outside the lid body 1. The electromagnet extends or retracts upon receiving a control signal and controls the movement of the indicator 3 relative to the lid body 1 through the indicator hole 101.

[0019] A circuit board 4 is fixed inside the control cavity 102. A control module is mounted on the circuit board 4, and the output of the control module is electrically connected to the electromagnet. The control module can be an existing control chip, etc. A temperature sensor is electrically connected to the input of the control module. A perforated temperature sensor probe is inserted into a perforation in the inner wall of the control cavity, and the area around it can be filled with food-grade sealant to obtain temperature information.

[0020] The kettle lid body 1 has an extension 108, on which a power supply contact 106 is fixed. The power supply contact 106 is connected to the battery management module of the circuit board 4 via a wire 107, converting the power supply from the electric kettle body 7 into the voltage required by the circuit board 4, for example, converting mains power into the usable 5-24V, to power the components on the circuit board 4. The power supply contact 106 is connected to the power supply of the electric kettle body 7. Alternatively, the kettle lid body 1 of the present invention does not have a power supply contact 106, but a power supply battery is fixed in the control cavity 102, and the power supply battery powers the circuit board 4.

[0021] As a preferred embodiment, a horn 5 is fixed on the lid body 1. The output of the control module is electrically connected to the horn 5. When the temperature sensor receives a signal indicating that the water is boiling or close to boiling point, it sends the signal to the control module on the circuit board 4. The control module controls the horn 5 to emit an audible alert and can also drive an electromagnet to control the indicator 3 to move up and down to provide the alert. In this embodiment, the electromagnet is arranged vertically to achieve the vertical movement of the indicator; in other embodiments, the electromagnet can be arranged horizontally to achieve the horizontal movement of the indicator.

[0022] The control module uses an existing control chip, which can control the operation of the electromagnets individually or in batches.

[0023] The sound-generating module, electromagnet, etc. of the present invention can be plugged into and connected to the circuit board 4 via connectors.

[0024] There are two types of electromagnets. Type 1: The electromagnet is a push-pull type electromagnet 201. The output end of the push-pull type electromagnet 201 is fixedly connected to the indicator 3 through the connecting post 105. That is, the connecting post 105 passes through the indicator hole 101 and connects to the indicator 3, so that the indicator 3 jumps up and down.

[0025] Method 2: The electromagnet is a DC chuck electromagnet 202. The bottom of the indicator 3 is connected to the indicator hole 101 via a spring 203. A magnet is fixed to the bottom of the indicator. When the DC chuck electromagnet 202 is energized, it generates magnetic force, which repels the magnet, causing the spring 203 to compress and the indicator 3 to move upward. When the power is off, the spring 203 expands elastically and the indicator 3 moves downward.

[0026] On the other hand, the present invention provides a kettle, including an electric kettle body 7 and the aforementioned kettle lid. A heating inner liner 701 is fixed inside the electric kettle body 7. A power supply 703 of the electric kettle is connected to a heating wire 702 through a first wire 704, and the heating wire 702 supplies power to the heating inner liner 701. A mating contact 705 is fixed on the electric kettle body 7. The power supply is electrically connected to the mating contact 705 through a second wire 706. The mating contact 705 is electrically connected to the power supply contact 106.

[0027] The heating wire is connected to 120V or 220V household electricity via a first wire. The power supply 703 of the electric kettle can step down the voltage in the voltage conversion circuit inside the kettle body via a second wire, for example, transforming the mains power into a safe low voltage of 5V-24V, and then electrically connecting it to the mating contacts to supply power to the kettle lid. Alternatively, the power supply 703 of the electric kettle can be connected to the mating contacts via the second wire to achieve voltage reduction operation inside the kettle lid.

[0028] The main body 7 of the electric kettle is shaped like a large duck, and the indicator 3 is shaped like a small duck.

[0029] The shape of the present invention is not limited to the above-described shape. It can also be that the main body 7 of the electric kettle is in the shape of the moon and the indicator 3 is in the shape of the star.

[0030] The power supply for the internal components of the kettle lid of the present invention can be provided by the power supply line of the heating wire 702 of the electric kettle body 7. This power supply line can be connected to the heating wire 702 through the existing water-on-off module 707, and automatically disconnected when the water boils.

[0031] Compared with existing technologies, the advantages of this invention are as follows: This invention uses an electromagnet to drive the dynamic displacement of the indicator, which differs from traditional buzzers / lights and meets the needs of young users for creative home furnishings. The novel and intuitive prompting method of this invention enhances the user experience; the combination of a horn and the mechanical movement of the indicator achieves multi-dimensional prompting through "sound and motion," avoiding the shortcomings of single prompting methods being easily overlooked. Multi-sensory collaborative prompting enhances interactive feedback; creative designs such as a large duck-shaped kettle body with a small duck indicator and a moon with stars enhance the added value of the product; the creative design of this invention combines practicality and decoration.

[0032] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
