Background
Electric kettles are often provided with a water adding mechanism for introducing water into the kettle body. At present, pipelines are additionally arranged at the bottom of a kettle seat and a kettle body in the market, so that the electric heating kettle which can supply water into the kettle body from the bottom of the kettle body through a water adding pipe can be realized, and automatic water adding is realized.
Generally, the water tank is arranged at a lower position, the water adding pipe and the water outlet thereof are arranged at a higher position, and the water adding system adopts a water pump to pump water from the water tank to the water outlet of the water adding pipe, so that the water is delivered to the inside of the kettle through the water outlet.
In the water kettle, the water inlet system of the water pump is controlled by a control device, and the water pump can be automatically opened or closed according to the water level in the kettle body, so that the automatic control of water adding of the water kettle is realized.
The water pump adds water to the kettle body through the water adding pipe, when the water pump is closed, a certain amount of water still remains in the water adding pipe, and the problem must be faced, otherwise, when the kettle body is separated from the kettle seat, the rest water flows back to the outside of the kettle body along the water adding pipe.
In the prior art, the upper coupler and the lower coupler are respectively provided with the water adding pipe and the water supply pipe, and the valve plate is arranged in the water adding pipe of the upper coupler, so that when water does not need to be added or the kettle body leaves the kettle seat, the water adding pipe can be sealed by the valve plate to prevent the remaining water from flowing out from the water adding pipe.
However, this structure brings about the following fatal drawbacks. When the water adding pipe is separated from the water supply pipe, the water supply pipe is filled with water which is not led into the kettle body, slightly arched water beads can be remained at the top end of the water supply pipe, when the water adding pipe is jointed with the water supply pipe again, the water beads can permeate out along the gap between the water adding pipe and the water supply pipe, and in order to solve the problem, higher requirements on the precision of parts in the aspect of manufacturing must be provided. And secondly, the valve plate is stressed by the pressure of cold and hot water for a long time in use, impurities exist in the water, scale is easily formed, and the scale is easily accumulated on the valve plate, so that the surface of the valve plate cannot be kept flat, and light and micro water is easily leaked in the use process. In electric kettles, the coupler is extremely dangerous once there is water infiltration or leakage, and it can cause malfunction, even electric shock.
