Description

Water dispenser capable of discharging residual water immediately Technical Field The utility model relates to the field of water dispensers, in particular to a water dispenser capable of immediately discharging residual water. Background The existing water dispenser equipment is usually connected with a water storage container and a valve through a water delivery pipe, and the water flow is controlled to be opened and closed by an electromagnetic valve or a mechanical valve. When a user takes water, the valve is opened, and after the water reaches the required water quantity, the valve is closed to stop water outlet. However, this conventional structure has a remarkable disadvantage in that, after the valve is closed, a part of the residual water which is not discharged is retained in the water pipe. The residual water is stored in the pipeline for a long time, bacteria are easy to breed, a biological film is formed, secondary pollution risks are caused, the pipeline is possibly damaged due to icing expansion in a low-temperature environment, algae growth is accelerated in a high-temperature environment, in addition, mineral deposition generated after the residual water is contacted with air can gradually form scale, the drinking taste is affected, the problems of reduced inner diameter of the pipeline, blocked water flow and the like are caused, the requirements of the drinking equipment on sanitary conditions are very strict, and the constant-temperature drinking equipment for a mother and an infant are particularly required to be avoided. The conventional technology can only drain part of the residual water in the pipeline, and does not completely solve the problem that the residual water stays in the pipeline. In the prior art, two main solutions are provided for discharging the residual water in the water dispenser pipeline, such as the method disclosed in patent publication No. CN217907373U, which is to provide a collecting tank for collecting the residual water, and to discharge the residual water in the pipeline into the collecting tank before each use of water. The other method is that the two-way pump is arranged on the pipeline, the switch valve is arranged at the water outlet of the water storage kettle, when the water dispenser discharges water, the switch valve is opened, the two-way pump conveys the water in the water storage kettle to the water outlet nozzle module, after the water discharge is finished, the two-way pump reversely conveys the residual water in the pipeline back to the water storage kettle, and after the residual water in the pipeline returns, the switch valve is closed, but the residual water in the pipeline needs to be conveyed back to the water storage kettle each time by using the two-way pump, the water source in the water storage kettle is easy to deteriorate, and the two-way pump pumps the water back and forth each time, so that the service life of the water dispenser is also shortened. Therefore, a novel structure capable of actively removing residual water in a water delivery pipe is needed, and automatic treatment of the residual water in the pipeline is realized while the water outlet control function is ensured, so that the sanitary safety level of drinking water is improved, the water is accurately used, and the service life of equipment is prolonged. Disclosure of utility model Therefore, in order to solve the above problems, the present utility model provides a water dispenser capable of discharging residual water in real time. The utility model is realized by the following technical scheme: The water dispenser capable of discharging residual water immediately comprises a water dispenser, a water delivery pipe and a water pump, wherein the water delivery pipe is connected with the water pump, the water dispenser comprises a water outlet, a valve seat connected with the water outlet of the water dispenser, the valve seat comprises an inlet and an outlet which are communicated with the water outlet, a telescopic piece and a blocking piece connected with the telescopic piece are sequentially arranged between the inlet and the outlet of the valve seat, the inlet of the water delivery pipe is connected with a movable connecting piece, the movable connecting piece is hollow and is provided with two ends which are open, the movable connecting piece is arranged at one end of the outlet of the valve seat and can translate along the axial direction, in a first state, the movable connecting piece extends into the valve seat from the outlet of the valve seat and jacks up the blocking piece, the valve seat is communicated with the water delivery pipe, in a second state, the movable connecting piece is separated from the valve seat, and the blocking piece is reset under the elastic action of the telescopic piece and seals the outlet of the valve seat. Preferably, a hollow flexible interface is further arranged between the blocking piece and the outlet of the valve seat, two
