The water outlet head 1 and the liquid heating appliance 3 according to some embodiments of the present invention will be described with reference to fig. 1 to 9.

The first embodiment is as follows:

as shown in fig. 1 and fig. 2, according to the embodiment of the first aspect of the present invention, the present invention provides a water outlet head 1, a first space 12 is defined in the water outlet head 1, a second space 14 and a liquid conducting structure 102 are defined in the water outlet head 1, the liquid conducting structure 102 connects the first space 12 and the second space 14, a water inlet 16 is connected with the first space 12, and a water outlet 18 is connected with the second space 14.

In this embodiment, the necessary structure of the water outlet head 1 proposed by the present invention is limited.

In this structure, the first space 12 is a water storage structure of a book outlet head, and after the liquid flows into the first space 12 from the water inlet 16, the liquid does not immediately flow into the second space 14, and the liquid is accumulated in the first space 12 and rises to the liquid level in the first space 12 along with the increase of the liquid, so that the liquid is temporarily stored in the first space 12. The liquid conducting structure 102 is a communicating structure between the first space 12 and the second space 14, when the liquid level in the first space 12 rises, the liquid level in the liquid conducting structure 102 rises together, when the liquid level in the liquid conducting structure 102 rises to a certain height, the liquid flows into the second space 14 from the liquid conducting structure 102 to form a liquid flow path from the first space 12 to the second space 14, and the liquid flow path continuously and continuously flows under the pressure of the liquid collected in the first space 12 until most of the liquid in the first space 12 is pumped into the second space 14. The second space 14 is a drainage structure of the water outlet head 1, and after the liquid flows into the second space 14, the liquid is drained out of the water outlet head 1 through a drainage port communicated with the second space 14 for use by a user.

This embodiment realizes continuous water discharge and stable water discharge of the water outlet head 1 by introducing the communicating vessel principle. The communicating structure enables the water outlet head 1 to store liquid in the first space 12 at the initial stage of water outlet, and to store the liquid in the first space 12 in advance by air suction in the subsequent water discharging process, so that the water flow fluctuation caused by the flow change is transferred into the first space 12, and the water flow at the water outlet 18 is prevented from being disordered or splashed due to the sudden change of the flow of the liquid flowing into the water inlet 16. Therefore, the problems that the liquid is disordered and even splashed when the water outlet 18 is shifted at the flow rate in the initial stage of flow change in the existing water outlet head 1 structure are solved, and a user is prevented from being scalded by disordered water flow or splashed liquid.

Moreover, the communicating vessel structure can ensure continuous water output from the water outlet 18 on the basis of solving the technical problems, the liquid continuity is kept under the condition of keeping the flow rate of the water outlet 18 stable, and the water outlet head 1 continuously outputs water before the liquid level in the first space 12 is lower than the lowest position of the liquid communicating structure, so that most of the liquid in the first space 12 is pumped out, and part of the residual liquid can volatilize in a short time, thereby avoiding the problem of liquid deterioration caused by a large amount of liquid accumulated in the first space 12, and further ensuring the quality of the output water.
