Description

Liquid outlet device, brewing device and brewing method Technical Field The disclosure relates to the technical field of household appliances, in particular to a liquid outlet device, a brewing device and a brewing method. Background Along with the improvement of the living standard of people, various brewing devices appear on the market, and coffee, tea and the like can be automatically brewed. When the brewing device is provided with a plurality of liquid outlets, a user is required to operate and select the liquid outlets to discharge liquid, the traditional brewing device is complex in operation, and human operation errors are easy to generate. Disclosure of Invention In order to solve the technical problems, the present disclosure provides a liquid outlet device, a brewing device and a brewing method. The first aspect of the present disclosure provides a liquid outlet device, comprising: The liquid containing cup is used for receiving liquid, a first liquid outlet and a second liquid outlet are formed in the bottom of the liquid containing cup, a siphon device is arranged at the first liquid outlet, and an opening and closing structure is arranged at the second liquid outlet; when the liquid in the liquid containing cup is discharged through the siphon device, the opening and closing structure is closed. In the implementation process, liquid is added into the liquid containing cup, and the opening and closing structure is controlled to be closed, so that the liquid in the liquid containing cup can be discharged from the first liquid outlet through the siphon device. When liquid is required to be discharged from the second liquid outlet, the liquid can be discharged from the second liquid outlet under the action of gravity only by controlling the opening and closing structure to be opened. The liquid amount of the liquid in the liquid containing cup is controlled to be larger than a threshold value, namely the height of the liquid is higher than the highest point of the siphon channel, the liquid in the liquid containing cup enters along the inlet of the siphon channel and flows along the siphon channel to be discharged from the first liquid outlet after passing through the highest point of the siphon channel. The liquid amount of the liquid in the liquid containing cup is controlled to be smaller than a threshold value, namely the liquid height is lower than the highest point of the siphon channel, the liquid in the liquid containing cup cannot be discharged from the siphon channel, at the moment, the liquid is controlled to stay in the liquid containing cup for a preset time, and the opening and closing structure is controlled to be opened, so that the liquid can be discharged from the second liquid outlet. When the liquid is sequentially added for two times, the liquid amount of the first liquid in the liquid containing cup can be controlled to be larger than a threshold value, namely the first liquid in the liquid containing cup can enter along the inlet of the siphon channel and is discharged from the first liquid outlet after flowing through the highest point of the siphon channel along the siphon channel, the liquid amount of the second liquid in the liquid containing cup is controlled to be smaller than the threshold value, so that the second liquid in the liquid containing cup cannot be discharged from the siphon channel, and after the second liquid stays in the liquid containing cup for a preset time, the opening and closing structure is controlled to be opened, so that the second liquid is discharged from the second liquid outlet. On the one hand, the siphon device is convenient for the rapid flow of the liquid in the liquid containing cup, reduces the residual of the liquid in the liquid containing cup and reduces the influence on the liquid discharged from the second liquid outlet, and on the other hand, the liquid rapidly flows to the siphon device, reduces the pressure on the second liquid outlet and improves the stability of the opening and closing structure of the second liquid outlet. Further, the liquid outlet device further comprises: the first liquid outlet is arranged corresponding to the first cup body; and the negative pressure assembly is respectively connected with the liquid containing cup and the first cup body so as to form negative pressure in the liquid containing cup and the first cup body. In the realization process, the negative pressure component enables the liquid containing cup and the first cup body to be in a negative pressure state, so that on one hand, the pressure balance between the liquid containing cup and the first cup body is promoted, the liquid is discharged from the first liquid outlet rapidly by the siphon device, the liquid residue in the process of liquid discharge through the first liquid outlet is reduced, the influence on the liquid discharged from the second liquid outlet is reduced, on the other hand, the liquid is promoted to flow to the first l
