When water exists in the kettle body 1, the interior of the third branch pipe 23 is controlled to be negative pressure relative to the inner cavity, at the moment, the first branch pipe 21 is communicated with the third branch pipe 23, the second branch pipe 22 is closed, and the water in the inner cavity of the kettle body 1 flows to the third branch pipe 23 to be discharged. When water is required to be added into the inner cavity of the kettle body 1, the third branch pipe 23 is controlled to be in positive pressure relative to the inner cavity, at the moment, the first branch pipe 21 is closed, the second branch pipe 22 is communicated with the third branch pipe 23, and water is sent to the inner cavity of the kettle body 1 through positive pressure, so that automatic water feeding is realized.

The first sealing member 24 is located inside the closed space, and when the third branch pipe 23 is under negative pressure, that is, the closed space is under negative pressure, the first sealing member 24 is pushed away from the closed space by the external pressure, so that the first branch pipe 21 is communicated with the third branch pipe 23. At the same time, the second branch pipe 22 is firmly pressed outside the closed space by the external pressure, and thus is in a closed state. When the third branch pipe 23 is at a positive pressure, i.e., the enclosed space is at a positive pressure, the first sealing member 24 is firmly pressed against the inside of the enclosed space by the internal pressure, and thus the first branch pipe 21 is in a sealed state. At the same time, the second branch pipe 22 is pushed outward from the inside of the closed space to be conducted, and therefore the second branch pipe 22 is in a state of being communicated with the third branch pipe 23. Therefore, when negative pressure or positive pressure is formed in the closed space relative to the inner cavity, the first branch pipe 21 or the second branch pipe 22 is alternatively conducted.

With reference to fig. 3 and 5, the first branch pipe 21 includes: a first gasket 241 is provided between the first seal 24 and the opening of the first branch pipe 21.

The stop wall 262 serves as a sliding stop and the permeable gap 263 prevents the tray 26 from blocking the bi-directional valve 2. In this embodiment, the limiting wall 262 is divided into several parts by the permeable gap 263. As an alternative embodiment, the stop wall 262 is C-shaped in cross-section.

If the water inlet pipe 14 is arranged at the bottom of the kettle body 1 or at a position on the side of the kettle body 1 close to the bottom, the sealing problem of the water inlet pipe 14 itself needs to be considered. And the structure at the bottom of the kettle body 1 is complex, the space is relatively compact, and the water inlet pipeline 14 is not favorable to be further distributed. Compared with the prior art, the kettle has the advantages that the handle 13 is simply assembled and directly connected with the guide pipe, so that the labor cost and the material cost are reduced, and the structure is simpler than the position of the kettle bottom, so that the product service life is prolonged, and the reliability is higher. As an alternative embodiment, the water inlet pipe 14 is arranged outside the kettle body 1, or the water inlet pipe 14 is communicated with the bottom of the kettle body 1.

Referring to fig. 5, when the two-way valve 2 is disposed in the middle of the thermostat 3, the kettle is placed on the base 6 to perform heating, water boiling, automatic water feeding and draining, and the like. Even the kettle rotates 360 degrees on the base 6, the kettle can work normally, and the user experience is met.

In this embodiment, as shown in fig. 1 and fig. 2, the method further includes: the base 6 comprises a coupler 5 adapted to the temperature controller 3, and a middle pipe 51 communicated with the third branch pipe 23 is arranged in the coupler 5.

Wherein, the bottom of the inner cavity is provided with a through hole for the first branch pipe 21 to pass through, and a sealing ring 12 is clamped between the first branch pipe 21 and the through hole. The sealing ring 12 improves the sealing performance of the two-way valve 2, namely, the end of the two-way valve 2, which is connected with the inner cavity of the kettle body 1, of the first branch pipe 21.

The working process is as follows:

the water inlet process comprises the following steps:

sends a signal to the water pump, so that the water pump sends water to the middle pipe 51, and the water enters the two-way valve 2 through the middle pipe 51 and enters from the third branch pipe 23 of the two-way valve 2. The second sealing element 25 slides towards the second branch pipe 22 pushed by water pressure to the right side, so that the second sealing element 25 and the second sealing gasket 25 are opened, and water enters the inner cavity of the kettle body 1 through the second branch pipe 22 through the water inlet pipeline in the handle 13, so that automatic water inlet is realized. At the same time, the first sealing member 24 is tightly pressed against the first sealing gasket 241 by the water pressure, i.e., the first sealing member 24 maintains a sealing state during the water inflow.

And (3) a drainage process:

a signal is sent to the water pump, so that the water pump sucks the water guide channel 61, and the middle pipe 51 communicated with the water guide channel 61 and the third branch pipe 23 are in a negative pressure state. Referring to fig. 3 and 5, when the closed space is in a negative pressure state, the pressure of the water on the side of the first sealing member 24 opposite to the inside of the kettle body is greater than the pressure on the side of the first sealing member 24 facing the closed space. At this time, the first sealing member 24 is passively moved downward, the drain spring 27 is compressed, and water flows down from the gap opened between the first sealing member 24 and the first sealing gasket 241, and is discharged through the middle pipe 51 and the water guide passage 11. The pressure applied to the side of the second sealing element 25 facing the sealed space is relatively small, and is pressed only on the second sealing pad 252 by the pressure difference, and the second sealing element is in a sealed state during the drainage process.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
