Technical Field
[0001] This utility model relates to the field of electric kettle technology, specifically to a convenient electric kettle. Background Technology
[0002] An electric kettle is a common household appliance, mainly used to quickly heat water, and has functions such as automatic power-off and anti-dry-boil.
[0003] When using an electric kettle, water needs to be heated to boiling to sterilize it. However, water that is too hot is not safe to drink directly and must be allowed to cool naturally or cooled with ice or other cooling agents. Natural cooling takes too long, and adding cooling agents requires specific substances, which is inconvenient for people who urgently need water. Currently, there are many types of electric kettles available, but none can accelerate the cooling of heated water. Therefore, a convenient electric kettle is needed to solve these problems.

The dust cover is screwed onto the support ring. An air inlet that is sealed by a filter screen is opened on the side of the dust cover. The dust cover can protect the small cooling fan. At the same time, the dust cover makes it easy to grip the kettle body and allow air to enter through the air inlet.
[0008] As a preferred technical solution for a convenient electric kettle according to this utility model, the U-shaped heat exchange tube is provided with fins, which can increase the contact area between the U-shaped heat exchange tube and the hot water, thereby increasing the heat exchange efficiency.
[0009] As a preferred technical solution for a convenient electric kettle according to this utility model, the other end of the U-shaped heat exchange tube is an elbow, which can prevent dust from entering the U-shaped heat exchange tube.
[0010] The beneficial effects of this utility model are as follows: Water is injected into the kettle body through the water inlet, and heat is exchanged between the water and the hot water inside the kettle body through the U-shaped heat exchange tube. A small cooling fan blows cool air into the air vent to cool the water, and the heat accumulated inside the U-shaped heat exchange tube is blown out from the other end of the U-shaped heat exchange tube, thereby cooling the hot water. At the same time, the structure of not blowing air directly onto the hot water can prevent water pollution. The detachable connection between the fan mounting base and the small cooling fan can facilitate the maintenance and replacement of the small cooling fan. The plug can prevent foreign objects from entering the kettle body through the water inlet when no water is injected. The dust cover can protect the small cooling fan and make it easy to grip the kettle body. Air is introduced into the kettle through the air inlet.

[0017] Example 1
[0018] like Figures 1 to 5As shown, this utility model discloses a convenient electric kettle. The technical solution includes a kettle body 1, a coupling heating base at the bottom of the kettle body 1, a handle with an integrated switch on one side of the kettle body 1, a spout at the upper end of the other side of the kettle body 1, a lid 2 on top of the kettle body 1, a water inlet 201 on the lid 2, a sealing ring 202 around the bottom of the lid 2, the sealing ring 202 being tightly fitted against the upper inner wall of the kettle body 1, and an air vent 203 at the center of the upper surface of the lid 2. The water inlet 201 is sealed by a stopper, allowing water to flow freely through the stopper. To prevent foreign objects from entering the kettle body 1 through the water inlet 201 when no water is being added; a support ring 3 is provided above the air guide 203, and the support ring 3 and the air guide 203 are coaxial. A fan mounting base 301 is provided inside the support ring 3; a small cooling fan 4 is installed in the fan mounting base 301 by screws. The air outlet of the small cooling fan 4 faces the air guide 203. The small cooling fan 4 is electrically connected to the switch on the handle and electrically connected to an external power supply through a coupling heating base. A dust cover 6 is provided on the support ring 3, and the dust cover 6 is screwed onto the support ring 3. A filter screen is provided on the side of the dust cover 6. The enclosed air inlet 601, protected by a dust cover 6, safeguards the small cooling fan 4 and facilitates gripping the kettle body 1. Airflow is drawn in through the air inlet 601. Below the air vent 203, a U-shaped heat exchange tube 5 is positioned. One end of the U-shaped heat exchange tube 5 is fully connected to the air vent 203, while the other end extends above the kettle lid 2. The U-shaped heat exchange tube 5 is equipped with fins 501, which increase the contact area between the tube and the hot water, thereby improving heat exchange efficiency. The other end of the U-shaped heat exchange tube 5 is a bend 502. The design prevents dust from entering the U-shaped heat exchange tube 5. Water is injected into the kettle body 1 through the water inlet 201, and heat is exchanged between the U-shaped heat exchange tube 5 and the hot water in the kettle body 1. Cool air is blown into the air vent 203 by the small cooling fan 4 to cool the water. The heat accumulated inside the U-shaped heat exchange tube 5 is blown out from the other end of the U-shaped heat exchange tube 5, thereby cooling the hot water. At the same time, the structure that does not directly blow air onto the hot water can prevent water pollution. The detachable connection between the fan mounting base 301 and the small cooling fan 4 makes it easy to repair and replace the small cooling fan 4.
[0019] The working principle of this utility model is as follows: After boiling water, when it is necessary to cool down the hot water inside the kettle body 1, the small cooling fan 4 is activated by the switch on the handle of the kettle body 1. External cold air enters the dust cover 6 through the air inlet 601, and then blows onto the U-shaped heat exchange tube 5 through the small cooling fan 4. The heat inside the U-shaped heat exchange tube 5 is blown out from the elbow 502. The hot water inside the kettle body 1 exchanges heat with the U-shaped heat exchange tube 5 through the fins 501 and the side wall of the U-shaped heat exchange tube 5. As the heat inside the U-shaped heat exchange tube 5 is blown out, the hot water begins to cool down.
