Description
技术领域technical field

现有的管式即热水壶，一般是设置有出水结构，出水结构具有出水嘴，发热管与出水结构连接，还包括回流结构，回流结构的进水口与出水结构导通，出水口与水箱导通。这种结构的工作原理为：水经过发热管时被快速加热至沸腾，然后沸腾后的热水从发热管流出进入到出水结构，然后从出水嘴流入到水杯中；当发热管断电停止加热时，发热管因为具有热惯性存在余热会继续对发热管中的水加热，被加热后的热水有部分从发热管溢出到出水结构中，由于出水结构体积通常均要求小，因而出水结构中的发热管出水口与回流结构的进水口的水平距离较短，且出水口要设置得足够低以保证加热时热水能快速流出，因而停止加热时流到出水结构中的水不能全部快速从回流结构的进水口回流到水箱中，仍有少量热水从出水嘴流出，给用户造成使用上的不便，比如存在烫伤的危险，或者水滴落到桌面上或者地板上造成不便。Existing tubular type hot water bottles are generally provided with a water outlet structure. The water outlet structure has a water outlet. The heating pipe is connected to the water outlet structure. It also includes a return flow structure. Pass. The working principle of this structure is: when the water passes through the heating pipe, it is quickly heated to boiling, and then the boiled hot water flows out from the heating pipe into the water outlet structure, and then flows into the water cup from the spout; when the heating pipe is powered off, the heating stops At this time, the heating pipe will continue to heat the water in the heating pipe because of its thermal inertia, and the residual heat will continue to heat the water in the heating pipe. Part of the heated hot water will overflow from the heating pipe into the water outlet structure. Since the volume of the water outlet structure is usually required to be small, the water outlet structure The horizontal distance between the water outlet of the heating pipe and the water inlet of the return structure is relatively short, and the water outlet should be set low enough to ensure that hot water can flow out quickly during heating, so when the heating is stopped, all the water flowing into the water outlet structure cannot be quickly removed from the structure. The water inlet of the backflow structure flows back into the water tank, and a small amount of hot water still flows out from the water outlet, which causes inconvenience to the user, such as the risk of burns, or the inconvenience caused by water dripping on the table or the floor.
