[0058] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model are further described in conjunction with the accompanying drawings, but the present utility model is not limited to these embodiments.

[0059] As Figures 1 - 4 shown, an electric hot water kettle with a cooling function includes:

[0060] A kettle body 1, which has a water filling cavity 11 therein;

[0061] A power supply base 4, which is used to connect to a power source. The kettle body 1 is placed on the placement position of the power supply base 4 and is electrically connected to the power supply base 4;

[0062] The cooling component 3 is installed on the power supply base 4, and the cooling component 3 is used to cool the liquid in the water filling cavity 11.

[0063] Among them, the cooling component 3 has;

[0064] The cooling box 33 is installed on the power supply base 4, and its interior is used to hold cold water;

[0065] The cooling pipe 32 is installed in the cooling box 33. The water inlet 34 of the cooling pipe 32 is connected to the water filling cavity 11 through a water pipe;

[0066] The water pump assembly is installed in the power supply base 4 and is connected to the water filling cavity 11 and the water inlet 34 of the cooling pipe 32 through a water pipe.

[0067] After the liquid in the kettle body 1 boils, the water pump assembly pumps the water out of the water filling cavity 11 and transports it into the cooling pipe 32. The cooling pipe 32 located in the cooling box 33 will be fully immersed in the cold water, so that the hot water in the cooling pipe 32 and the cold water in the cooling box 33 can exchange heat, thus achieving the purpose of cooling the water.

[0068] Other liquid or solid coolants can also be contained in the cooling box 33. Since the technical solution is commonly used in daily life, the preferred coolant is cold water.

[0069] As a preferred embodiment, the cooled water can be made to flow back into the water filling cavity 11 again, and the cooled water is mixed with the warmer water in the water filling cavity 11, so as to achieve the purpose of evenly reducing the water temperature in the water filling cavity 11. To meet the needs of some users who cannot drink water at too low a temperature.

[0070] Specifically Figure 2 and Figure 3 As shown, the cooling pipe 32 has an upwardly spirally arranged rising cooling section 36 and a downwardly spirally arranged descending cooling section 37, and the rising cooling section 36 is connected to the descending cooling section 37;

[0071] The descending cooling section 37 is arranged around the outside of the rising cooling section 36, or the rising cooling section 36 is arranged around the outside of the descending cooling section 37.

[0072] As a preferred technical solution, in this embodiment, the descending cooling section 37 is arranged around the outside of the rising cooling section 36, so that the hot water flowing through the cooling pipe 32 can fully contact the cold water in the cooling box 33, thereby maximizing the heat exchange efficiency.

[0073] A gap 38 is left between the descending cooling section 37 and the ascending cooling section 36 so that the cold water in the cooling box 33 can be evenly distributed on the outside of the descending cooling section 37 and the ascending cooling section 36 and a certain distance is maintained around the descending cooling section 37 and the ascending cooling section 36.

[0074] In this way, more cold water can be present between the descending cooling section 37 surrounding the ascending cooling section 36. When the hot water passes through the ascending cooling section 36, the hot water exchanges heat with the cold water around the ascending cooling section 36. Since there is enough cold water between the descending cooling section 37 and the ascending cooling section 36, this part of cold water has a larger heat capacity. Therefore, when the hot water enters the descending cooling section 37, the cold water outside the descending cooling section 37 is less affected by the hot water in the ascending cooling section 36, so that there is still enough cold water outside the descending cooling section 37 to cool the water in the descending cooling section 37.

[0075] like Figures 1 - 6 As shown, a heating plate 21 is arranged at the bottom of the kettle body 1. The heating plate 21 can heat the water in the water chamber 11 when powered on. A water outlet channel 22 and a water return channel 23 are opened on the heating plate 21.

[0076] Both of them are provided with a one-way valve assembly, and the water outlet channel 22 and the water return channel 23 are connected to the water filling chamber 11. The one-way valve assembly is used to block the water outlet channel 22 and the water return channel 23 to prevent the water from flowing out of the water filling chamber 11 from the water outlet channel 22 and the water return channel 23 before the water is boiled.

[0077] A second water outlet channel 45 and a second water return channel 42 are protrudingly provided on the placement position on the power supply base 4, and a top head 43 is protrudingly provided on the upper ends of the second water outlet channel 45 and the second water return channel 42;

[0078] The second water outlet channel 45 is connected to the water pump assembly through a water pipe, and the second water return channel 42 is connected to the water outlet 35 of the cooling pipe 32 through a water pipe;

[0079] When the kettle body 1 is placed in the placement position, the ejector head 43 is inserted into the water outlet channel 1 22 and the water outlet one-way valve assembly 5 is opened, so that the water outlet channel 2 45 and the water outlet channel 1 22 can be connected, so that the water pump assembly can pump water out of the water chamber 11.

[0080] like Figures 1 - 8 As shown, the upper end of the second water return channel 42 is also protrudingly provided with a top head 43;

[0081] When the kettle body 1 is placed in the placement position, the ejector head 43 is inserted into the return water channel 23 to open the return water one-way valve assembly 6.

[0082] Further, a check valve assembly 6 is provided in the first return water passage 23. The check valve assembly 6 includes:

[0083] A check valve body 61 of the return water check valve;

[0084] A sealing seat 63 is arranged in the first water outlet passage 22 or the first return water passage 23, and a water passing hole 65 is formed in the middle thereof;

[0085] A sealing member 62 is movably arranged in the first water outlet passage 22 or the first return water passage 23 and is located above the sealing seat 63.

[0086] As a preferred embodiment, the first return water passage 23 is arranged at the bottom of the water filling cavity 11. Due to the action of gravity, the sealing member 62 can be abutted against the upper end of the sealing seat 63 to block the water passing hole 65, so that the first return water passage 23 is closed to prevent water from flowing out through the first return water passage 23.

[0087] As another preferred embodiment, specifically as shown in FIGS. 7 and Figure 8 The return water check valve assembly 6 further includes a spring 64, and the spring 64 is arranged in the first return water passage 23.

[0088] The spring 64 is used to press the sealing member 62 against the sealing seat 63, so that the sealing member 62 can be more closely stacked at the end of the sealing seat 63 to achieve the purpose of blocking the water passing hole 65. It can also prevent the situation that the sealing member 62 is separated from the sealing seat 63 when the kettle body 1 shakes, improving the stability during use.

[0089] As shown in Figures 1 - 8 The water pump assembly includes a water pump 8, and the water outlet end of the solenoid valve 81 is connected to the solenoid valve 81 and is connected to the water inlet 34 of the cooling box 33 through the solenoid valve 81. The solenoid valve 81 can control the closing of the water circuit.

[0090] When the same check valve structure as that in the first return water passage 23 is provided in the first water outlet passage 22, placing the kettle body 1 in the connecting groove 46 will also conduct the first water outlet passage 22, and water will flow out of the water filling cavity 11 through the first water outlet passage 22. By providing the solenoid valve 81 to close the first water outlet passage 22, it can prevent water from flowing out of the water filling cavity 11 in advance when the water is not boiled.

[0091] Specifically as shown in Figure 6 The cooling box 33 is further provided with a liquid discharge port 39, and the liquid discharge port 39 is used to discharge the cold water in the cooling box 33, so as to facilitate the user to collect and clean.

[0092] A cover 31 is arranged on the top of the cooling box 33, and the cover 31 can be removed from the upper end of the cooling box 33, so that the upper end of the cooling box 33 is opened, facilitating the user to add coolant into the cooling box 33.

[0093] As shown Figures 1 - 8 in FIG. Figures 1 - 8 , the power supply base 4 is formed with a connection groove 46, and a lower coupler 41 is disposed in the connection groove 46;

[0094] When the kettle bottom 2 is disposed in the connection groove 46, the lower coupler 41 can be connected to the upper coupler 25 on the kettle bottom 2, so as to realize the electrical connection between the kettle and the power supply base 4.

[0095] A second water return channel 42 is formed in the connection groove 46, and a top head 43 is formed at the upper end of the second water return channel 42.

[0096] When the lower coupler 41 can be connected to the upper coupler 25 on the kettle bottom 2, the second water return channel 42 is connected to the first water return channel 23.

[0097] Furthermore, a positioning portion 24 is formed on the circumferential side of the kettle bottom 2. A positioning groove 47 is formed on the circumferential side of the connection groove 46, and the positioning portion 24 can be placed in the positioning groove 47.

[0098] When the positioning portion 24 and the positioning groove 47 are aligned, the second water return channel 42 is also aligned with the first water return channel 23, so as to facilitate accurately placing the kettle in the connection groove 46 and prevent damage caused by collision between the kettle bottom 2 and the second water return channel 42.
