Turning now to fig. 2A, 2B, 6, 8A, 8B, 9-12, the lower coupler 12 has a lower coupler central aperture 121, a portion of the airflow generating unit 13 corresponds to the lower coupler central aperture 121 of the lower coupler 12, the upper coupler 22 has an upper coupler central aperture 221, and a portion of the drainage 232 corresponds to the upper coupler central aperture 221 of the upper coupler 22, wherein upon coupling of the upper coupler 22 and the lower coupler 12, the upper coupler 22 and the lower coupler 12 cooperate with each other to achieve automatic alignment of the drainage 232 of the airflow distributing unit 23 and the airflow generating unit 13, such that a user does not need to specifically align the drainage 232 of the airflow distributing unit 23 and the airflow generating unit 13 when the kettle body 21 is carried on the carrying surface 111 of the base body 11. In other words, the upper coupler 22 and the lower coupler 12 have a guiding function for guiding the drainage portion 232 of the air flow distribution unit 23 and the air flow generation unit 13 to be automatically connected.

Preferably, the drainage portion 232 of the airflow distribution unit 23 and the airflow generation unit 13 are connected in a plug-in manner, so as to avoid air leakage at the connection position of the drainage portion 232 and the airflow generation unit 13.

Specifically, a portion of the air flow generating unit 13 extends to the lower coupler center through hole 121 of the lower coupler 12 in such a manner as to allow the lower coupler 12 to surround a portion of the air flow generating unit 13, and accordingly, a portion of the drainage portion 232 extends to the upper coupler center through hole 221 of the upper coupler 22 in such a manner as to allow the upper coupler 22 to surround a portion of the drainage portion 232, and by allowing a portion of the air flow generating unit 13 to extend to the lower coupler center through hole 121 of the lower coupler 12 and allowing a portion of the drainage portion 232 to extend to the upper coupler center through hole 221 of the upper coupler 22, the drainage portion 232 and the air flow generating unit 13 are connected in a plug-in manner so as to avoid air leakage at the connection position of the drainage portion 232 and the air flow generating unit 13 when the kettle body 21 is carried on the carrying surface 111 of the base body 11 to allow the upper coupler 22 and the lower coupler 12.

More specifically, referring to fig. 6 to 8B, the air flow generating unit 13 includes at least one air pump 131 and a guide insertion column 132 connected to the air pump 131, the air pump 131 has an air pump outlet 1311, the guide insertion column 132 has a guide passage 1321, and the air pump outlet 1311 of the air pump 131 and the guide passage 1321 of the guide insertion column 132 are communicated to allow the air flow generated by the air pump 131 to flow toward the guide passage 1321 of the guide insertion column 132. The top end of the guide post 132 is mounted to the lower coupler center bore 121 of the lower coupler 12 to allow the lower coupler 12 to wrap around the top end of the guide post 132.

Turning now to fig. 3A-4B, 9-12, the dispensing portion 231 has a dispensing channel 2311 and a plurality of dispensing apertures 2312 in communication with the dispensing channel 2311, wherein the drain portion 232 includes a drain plug 2321 and a sealing assembly 2322, the drain plug 2321 having a drain channel 23211, the sealing assembly 2322 being operatively disposed to the drain channel 23211 of the drain plug 2321 to allow the drain channel 23211 of the drain plug 2321 to be opened or closed, a top end of the drain plug 2321 being disposed to the dispensing portion 231 in communication with the drain channel 23211 of the drain plug 2321 and the dispensing channel 2311 of the dispensing portion 231, a bottom end of the drain plug 2321 extending to the upper coupler center aperture 221 of the upper coupler 22 via the bottom aperture 213 of the jug 21 to allow the upper coupler 22 to surround the bottom end of the drain plug 2321. Preferably, referring to fig. 5, the distribution channel 2311 of the distribution portion 231 is a spiral channel in a top view.

With continued reference to fig. 9 to 12, when the kettle body 21 is carried on the carrying surface 111 of the base 11, the bottom end of the flow guiding plug 2321 and the top end of the flow guiding plug 132 are plugged to allow the air flow generating unit 13 and the flow guiding portion 232 to be connected. When the sealing assembly 2322 is operated to open the drainage passage 23211 of the drainage plug 2321, the air pump air outlet 1311 of the air pump 131, the drainage passage 1321 of the drainage plug 2321, the drainage passage 23211 of the drainage plug 2321, and the distribution passage 2311 and the distribution hole 2312 of the distribution part 231 are sequentially communicated to allow an air flow generated by the air pump 131 to sequentially flow through the air pump air outlet 1311 of the air pump 131, the drainage passage 23211 of the drainage plug 2321, the distribution passage 2311 of the distribution part 231, and the distribution hole 2312 of the distribution part 2321 to the water chamber 211 of the kettle body 21, wherein the air flow can actively take heat of the water bubbles in the rising water of the water chamber 211 contained in the kettle body 21 after being discharged to the water chamber of the kettle body 21 through the distribution hole 2312 of the distribution part 231, and the air flow can actively flow down in the rising water of the bubbles. When the sealing assembly 2322 is operated to close the drainage channel 23211 of the drainage plug 2321, the sealing assembly 2322 is used for preventing water contained in the water containing cavity 211 of the kettle body 21 from flowing back to the airflow generating unit 13 so as to ensure the sanitation of the kettle.

Referring to fig. 4A, 4B, and 9-12, the seal assembly 2322 further includes a seal holder 23221, a seal valve 23222, and a seal return element 23223, wherein the seal holder 23221 has a seal holder perforation 232211, the seal holder 23221 is fixedly mounted to the drain channel 23211 of the drain plug 2321 at a bottom end of the drain plug 2321, and the seal holder perforation 232211 of the seal holder 23221 is in communication with the drain channel 23211 of the drain plug 2321, wherein the seal valve 23222 and the seal return element 23223 are disposed to the drain channel 23211 of the drain plug 2321, respectively, and opposite ends of the seal return element 23223 abut against an inner wall of the drain channel 23211 of the drain plug 2321 and a top end of the seal valve 23222, respectively, to allow the seal valve 23222 to abut against or separate from the top end of the seal holder 23221 such that the drain plug 2321 is opened or closed by the drain channel 23211 of the drain plug 2321.

Specifically, when the air pump 131 starts to work to make the air flow generating unit 13 generate air flow, the air flow can push the sealing valve 23222 to separate from the top end of the sealing seat 23221 to open the drainage channel 23211 of the drainage plug 2321, and meanwhile, the sealing reset element 23223 is elastically deformed. When the air pump 131 stops working and the air flow generating unit 13 does not generate air flow, the seal reset element 23223 pushes the seal valve 23222 to be attached to the top end of the seal seat 23221 so as to close the drainage channel 23211 of the drainage plug 2321. It will be appreciated that, since the air flow generated by the air flow generating unit 13 is a continuous air flow, even though the air pump air outlet 1311 of the air pump 131, the air guide passage 1321 of the air guide insertion post 132, the air guide passage 23211 of the air guide insertion post 2321, the distribution passage 2311 of the distribution portion 231 and the distribution hole 2312 are sequentially communicated, the water contained in the water containing cavity 211 of the kettle body 21 is not guided to the air flow generating unit 13. In addition, when the air pump 131 is stopped, the seal return element 23223 immediately returns to the initial state, so that the seal valve 23222 is attached to the top end of the seal seat 23221 again, so as to prevent the water contained in the water containing cavity 211 of the kettle body 21 from flowing back to the air flow generating unit 13.

In this particular example of the water kettle of the present invention shown in fig. 1A to 12, the sealing valve 23222 is a ball valve and the sealing return element 23223 is attached to or detached from the top end of the sealing seat 23221 in such a manner as to allow the sealing valve 23222 to move up and down. Specifically, when the air pump 131 starts to operate to generate air flow from the air flow generating unit 13, the air flow can push the sealing valve 23222 to move upwards to separate the sealing valve 23222 from the top end of the sealing seat 23221, so as to open the drainage channel 23211 of the drainage plug-in column 2321, and simultaneously the sealing return element 23223 is elastically deformed, at this time, the air flow generated by the air pump 131 sequentially flows through the air pump air outlet 1311 of the air pump 131, the diversion channel 1321 of the drainage plug-in column 132, the diversion channel 23211 of the drainage plug-in column 2321, and the distribution channel 2311 and the distribution hole 2312 of the distribution part 231 to the water cavity 211 of the kettle body 21, and after being discharged to the water cavity 211 of the kettle body 21 through the distribution hole 2312 of the distribution part 231, the air flow can be generated at the bottom of water contained in the water cavity 211 of the kettle body 21, and actively takes heat of the rising water temperature to lower. When the air pump 131 stops working and the air flow generating unit 13 does not generate air flow, the seal reset element 23223 pushes the seal valve 23222 to move downward in the process of recovering the initial state, so that the seal valve 23222 is attached to the top end of the seal seat 23221, so as to close the drainage channel 23211 of the drainage plug 2321, and prevent the water contained in the water containing cavity 211 of the kettle body 21 from flowing back to the air flow generating unit 13.

Alternatively, in other specific examples of the water kettle of the present invention, the sealing valve 23222 is a membrane valve and the sealing return element 23223 is attached to or detached from the top end of the sealing seat 23221 in a manner allowing the sealing valve 23222 to deform up and down. Specifically, when the air pump 131 starts to operate to generate air flow from the air flow generating unit 13, the air flow can push the sealing valve 23222 to deform upwards to separate the sealing valve 23222 from the top end of the sealing seat 23221, so as to open the drainage channel 23211 of the drainage plug-in column 2321, and simultaneously the sealing return element 23223 is elastically deformed, at this time, the air flow generated by the air pump 131 sequentially flows through the air pump air outlet 1311 of the air pump 131, the flow guide channel 1321 of the drainage plug-in column 132, the flow guide channel 23211 of the drainage plug-in column 2321, and the distribution channel 2311 and the distribution hole 2312 of the distribution part 231 to the water cavity 211 of the kettle body 21, and after being discharged to the water cavity 211 of the kettle body 21 through the distribution hole 2312 of the distribution part 231, the air flow can be generated at the bottom of water contained in the water cavity 211 of the kettle body 21, and actively takes heat of the rising water temperature to lower. When the air pump 131 stops working and the air flow generating unit 13 does not generate air flow, the seal reset element 23223 pushes the seal valve 23222 to deform downwards in the process of recovering the initial state, so that the seal valve 23222 is attached to the top end of the seal seat 23221, so as to close the drainage channel 23211 of the drainage plug 2321, and prevent the water contained in the water containing cavity 211 of the kettle body 21 from flowing back to the air flow generating unit 13.
