[0002] An electric kettle is a common household appliance in every family life. The traditional electric kettle only has a single function of boiling water. If you want to make the boiled water reach a suitable drinking temperature, you can only let it cool naturally, which requires a long time of waiting. If the kettle lid is opened for heat dissipation, dust in the air will fall into the water and pollute the boiled water, which is time-consuming and troublesome.

[0003] Therefore, with the development of technology, more and more electric kettles with a cooling function have emerged on the market.

[0046] As shown in the figure, in order to solve the technical problem in the prior art that when cooling the water in the kettle, dust, bacteria, etc. in the air may contaminate the water in the kettle, thereby affecting the water quality, this application provides an electric kettle, which mainly consists of a kettle 10, a main body 20, a heat dissipation air duct 32 and a fan 31.

[0047] Specifically, the main body 20 has a power base for connecting the kettle 10. A heat dissipation air duct 32 is arranged inside the power base. The heat dissipation air duct 32 has an air inlet and an air outlet. A fan 31 is arranged inside the main body 20, and the fan 31 is connected to the air inlet of the heat dissipation air duct 32. There is a heat dissipation gap between the side wall of the power base and the outer wall of the kettle 10, and the air outlet of the heat dissipation air duct 32 faces the outer wall of the kettle 10. The fan 31 conveys cold air to the heat dissipation gap through the heat dissipation air duct 32 to cool the kettle 10, accelerating the cooling of the water in the kettle 10. At the same time, it avoids directly introducing external cold air into the kettle 10 to cool the water, which may cause problems such as dust and bacteria contaminating the water in the kettle 10 and then affecting the water quality. The way of cooling the water is cleaner and more hygienic.

[0048] Preferably, the body of the kettle 10 is made of high borosilicate glass material. The high borosilicate glass material has good thermal conductivity, which can improve the heat dissipation effect of the cold air conveyed by the fan 31 through the heat dissipation air duct 32 to the heat dissipation gap and accelerate the cooling rate of the water in the kettle 10.

[0049] In an embodiment, the power base is arranged in a groove portion 23 of the main body 20, so that when the kettle 10 is connected to the power base, there is a heat dissipation gap between the side wall of the power base and the outer wall of the kettle 10. This ensures that the cold air conveyed by the fan 31 through the heat dissipation air duct 32 blows towards the outer wall of the kettle 10, ensuring the cooling effect on the water in the kettle 10.

[0050] In an embodiment, the heat dissipation air duct 32 has a lower cover plate 33, and the lower cover plate 33 is used to close the bottom of the heat dissipation air duct 32, so that when the kettle 10 is connected to the power base, the air outlet of the heat dissipation air duct 32 faces the outer wall of the kettle 10. This ensures that the cold air conveyed by the fan 31 through the heat dissipation air duct 32 blows towards the outer wall of the kettle 10, ensuring the cooling effect on the water in the kettle 10.

[0051] Preferably, several first convex columns are arranged adjacent to the heat dissipation air duct 32 and the fan 31, and several second convex columns 331 are correspondingly arranged on the lower cover plate 33. The second convex columns 331 can be sleeved on the first convex columns 321 to make the lower cover plate 33 close the bottom of the heat dissipation air duct 32. This ensures that the cold air conveyed by the fan 31 through the heat dissipation air duct 32 blows towards the outer wall of the kettle 10, ensuring the cooling effect on the water in the kettle 10.

[0052] In an embodiment, the electric kettle of the present application further includes a pipeline system. The pipeline system is installed inside the main body 20, and the pipeline system includes a water inlet pipeline 41, a water pump 60 and a water outlet pipeline 70.

[0053] In this embodiment, specifically, the water inlet pipeline 41 is connected to the kettle 10, the water inlet pipeline 41 is connected to the water pump 60, and the water outlet pipeline 70 is connected to the water pump 60. A three-way solenoid valve is connected in the pipeline of the water inlet pipeline 41. Two of the openings of the three-way solenoid valve 50 are connected to the water inlet pipeline 41, enabling the control of the water delivery situation in the pipeline system.

[0054] It should be noted that the three-way solenoid valve 50 is mainly used to control the on-off or flow direction of the fluid. In the electric kettle, connecting the three-way solenoid valve 50 to components such as the control circuit board that can receive input signals, process data, execute logical control, and drive the electric kettle to work can achieve the automatic control of the fluid flow direction or flow rate, etc.

[0055] Preferably, the remaining opening of the three-way solenoid valve 50 is connected to an air inlet pipe 42, which can drain the pipeline system, prevent the residual water in the pipeline system from affecting the temperature of the next water outlet, and ensure the water outlet hygiene of the pipeline system. Specifically, the three-way solenoid valve 50 has a first working state and a second working state. In the first working state, the water inlet pipeline 41 closes the connection between the water pump 60 and the air inlet pipe 42 through the three-way solenoid valve, and at the same time, the water pump 60 is connected to the kettle 10 through the three-way solenoid valve 50, realizing the delivery of the water in the kettle 10 to the outside of the main unit 20 for the user to use.

[0056] Furthermore, in the second working state, the water inlet pipeline 41 closes the connection between the water pump 60 and the kettle 10 through the three-way solenoid valve 50, and at the same time, the water pump 60 is connected to the air inlet pipe 42 through the three-way solenoid valve 50. Under the action of the water pump 60, air enters the pipeline system from the air inlet pipe 42, squeezing out the residual water in the pipeline system, realizing the drainage of the pipeline.

[0057] In one embodiment, the main unit 20 has a water outlet port 22, and the water outlet port 22 is connected to the water outlet pipeline 70 to deliver the water in the kettle 10 to the outside of the main unit 20.

[0058] In one embodiment, the bottom of the kettle 10 has an upper coupler and a heating element electrically connected to the upper coupler. The power supply base has a lower coupler 21, and the lower coupler 21 can be electrically connected to the upper coupler. The lower coupler 21 can be connected to the power socket through a power cord. When the lower coupler 21 is connected to the power supply and the upper coupler is connected to the lower coupler 21, the heating element can heat the water in the kettle 10. Preferably, the water inlet pipeline 41 passes through the lower coupler 21. When the kettle 10 is connected to the power supply base of the main unit 20, the water inlet pipeline 41 is connected to the kettle 10, realizing the extraction of the water in the kettle 10 to the outside of the main unit 20 for the user to use.

[0059] It can be understood that the lower coupler 21 is electrically connected to other components of the electric kettle that need to be powered on for operation. The lower coupler 21 is connected to a power socket through a power cord to be powered on, and supplies power to other components of the electric kettle that need to be powered on for operation.

[0060] Preferably, the bottom of the main body 20 has a heat dissipation vent 24.

[0061] In one embodiment, a water flow sensor 80 is installed on the water outlet pipeline 70; a control circuit board is provided inside the main body 20, and the control circuit board is electrically connected to the water flow sensor 80 so that the electric kettle can discharge water quantitatively.

[0062] It should be noted that the control circuit board is a circuit board used to implement specific control functions in this electric kettle, and can be a microcontroller control board or other control circuit boards that can receive input signals, process data, execute logic control, and drive the electric kettle to work. Specifically, the control circuit board is also electrically connected to the three-way solenoid valve 50, the water pump 60, the heating element, and the blower 31 respectively, and the control circuit board is used to control the operation of the three-way solenoid valve 50, the water pump 60, the heating element, and the blower 31.

[0063] It should be noted that the water flow sensor 80 can detect the volume or mass of water flowing through the sensor, and the control circuit board is responsible for receiving input signals, processing data, controlling the operation of the device, and outputting. In this application, the volume or mass of water flowing through the sensor detected by the water flow sensor 80 is transmitted to the control circuit board in the form of a signal. The control circuit board can receive this signal, monitor the water output of the kettle 10, and when the water output reaches the preset water output target, the control circuit board controls the water pump 60 to stop pumping water, and at the same time controls the opening and closing of the relevant openings of the three-way solenoid valve 50 to achieve quantitative water output for the user.

[0064] Specifically, in this application, the water flow sensor 80 is connected to the control circuit board. After the user sets the water output of the electric kettle, the control circuit board controls the three-way solenoid valve 50 to enter the first working state. The water pump 60 pumps the water in the kettle 10 into the water outlet pipeline and outputs it outside the main body 20 for the user to use. The water flow sensor 80 detects the water volume flowing through the water outlet pipeline 70. When this water volume reaches the water output set by the user, the water flow sensor 80 transmits a signal to the control circuit board, and the circuit control board controls the electric kettle to stop discharging water, realizing the function of accurate quantitative water output of the electric kettle.

[0065] Preferably, the water flow sensor 80 of this application can also be used to detect whether there is water in the kettle 10. If there is no water, the sensor will send a signal to the control circuit, thereby avoiding heating the kettle 10 in a waterless state, preventing dry burning and damage, and thus preventing the occurrence of dangerous accidents.

[0066] Preferably, the water flow sensor 80 of the present application can also indirectly determine the water level in the kettle 10 by detecting the water flow rate through the water outlet pipe 70. When the water in the kettle 10 reaches the set water level, the water flow sensor 80 will send a signal to the control circuit, causing the electric kettle to automatically cut off the power and stop heating, which ensures that the water will not overflow or boil due to overheating, preventing dangerous accidents from occurring.

[0067] In one embodiment, a temperature sensor is installed in the kettle 10, and the temperature sensor is electrically connected to the control circuit board to monitor the temperature of the water in the kettle 10.

[0068] Specifically, the user sets the required water outlet temperature in advance. After the water in the electric kettle is boiled, the water temperature adjustment device in the electric kettle starts to work to cool the water. When the temperature sensor detects that the water temperature in the kettle 10 reaches the water outlet temperature set by the user, the temperature sensor transmits a signal to the control circuit board, and the control circuit board controls the fan 31 to stop working, realizing that the electric kettle can accurately cool the water so that the user can set the water outlet temperature of the electric kettle according to their own needs.

[0069] Specifically, the temperature sensor can also detect the water temperature in the kettle 10. When the water temperature reaches the set heating temperature, the sensor will send a signal to the control circuit board to stop the heating element from heating. By monitoring the water temperature, the temperature sensor can prevent the water in the kettle 10 from boiling over or causing dry burning due to overheating, thus protecting the equipment and user safety.

[0070] Preferably, the temperature sensor can also detect the water temperature and maintain it at a set constant temperature state to ensure that the water remains at a constant temperature within the required time.

[0071] In a preferred embodiment, the exterior of the host 20 has a control panel, and the control panel is electrically connected to the control circuit board. It should be noted that the control panel provides an interface for the user to interact with the electric kettle and has the functions of displaying information and controlling the electric kettle. The user's input is transmitted to the control circuit board through the control panel to execute the corresponding control logic. Specifically, the user can control the electric kettle to heat or stop heating the water through the control panel, and can also control the water output volume and water outlet temperature of the electric kettle through the control panel. Correspondingly, the control panel can display relevant information about the electric kettle, such as the water output volume, the water temperature in the kettle 10, etc.

[0072] In one embodiment, the kettle 10 has a kettle cover, which includes a first cover body 111 and a second cover body, wherein the second cover body 112 is placed in the first cover body 111 and is movably connected to the first cover body 111. The second cover body 112 has a pressing mechanism and a lifting mechanism, wherein the lifting mechanism is connected to the pressing mechanism, and the pressing mechanism is configured to allow a user to control the opening and closing of the second cover body 112 by pressing. The lifting mechanism can respond to the action of the pressing mechanism so that the second cover body 112 moves between the open and closed positions; when the second cover body 112 is in an open state, an opening is formed between the first cover body 111 and the second cover body 112 so that the water vapor in the kettle 10 is emitted through the opening, and when the water in the kettle 10 needs to be cooled down, this can further increase the cooling speed of the water in the kettle 10.

[0073] In a specific embodiment, the user sets the water outlet temperature of the electric kettle through the control panel, and the control circuit board controls the heating element to boil the water in the kettle 10, or when the water has been boiled, the control circuit board controls the fan 31 to blow out cold air, and the cold air blows toward the outer wall of the kettle 10 through the air outlet of the heat dissipation duct 32, thereby accelerating the cooling of the water in the kettle 10. At the same time, the second cover 112 on the kettle cover can be opened, so that the water in the kettle 10 is dispersed through an opening formed between the first cover 111 and the second cover 112, thereby accelerating the cooling speed of the water in the kettle 10. Afterwards, the temperature sensor is used to detect whether the water temperature reaches the water outlet temperature preset by the user. If the water temperature is still higher than the set water outlet temperature, the control circuit board continues to control the fan 31 to blow out cold air until the temperature sensor detects that the temperature of the water in the kettle 10 reaches the water outlet temperature set by the user. The control circuit board controls the three-way solenoid valve 50 to connect the water inlet pipe 41 to the kettle 10 and the water pump 60. Under the action of the water pump 60, the water in the kettle 10 is transported to the outside of the host 20 along the pipe system, so that the electric kettle 10 supplies water to the user according to the water outlet temperature set by the user.

[0074] On the other hand, when the water in the kettle 10 reaches the temperature set by the user, the electric kettle enters the keep warm state. When the temperature sensor detects that the temperature in the kettle 10 drops below the water outlet temperature set by the user, the control circuit board controls the heating element to heat the water. When the water temperature returns to the water outlet temperature preset by the user, the control circuit board controls the heating element to stop heating.

[0075] If the user also sets the water output through the control panel, the water flow sensor 80 detects the amount of water flowing through the water outlet pipe 70. When the water volume reaches the water output set by the user, the control circuit board controls the corresponding components of the electric kettle to stop pumping water and discharging water.
