Abstract
The water pump is mainly composed of a water pump and a vacuum pump. The vacuum pump is connected with the water pump through an air inlet pipe. The water pump is mainly composed of a water pump body (37), a water pump impeller (34) and a water pump shaft (23). The water pump impeller (34) is installed on the water pump shaft (23) that is positioned in an impeller chamber (52). The air inlet pipe (11) of the vacuum pump is connected with the water pump through an air inlet pipe joint (51) on a water storage chamber (49). The connecting part of a water outlet chamber (40) of the water pump and the water storage chamber (49) is equipped with a sealed bottom plate (41). A guide rod (39) is installed on the sealed bottom plate (41). When air in the water pump needs to be emptied, firstly, the guide rod is pressed down, which enables the vacuum pump to work, pumping the water pump into a vacuum state. When the water level is achieved, the water pump begins to work, that is, to pump water. At last, when the water pump stops working, gravity makes the guide rod (39) fall to seal the water storage chamber (49), avoiding water from overflow. The utility model is reasonable in structure, convenient to operate, free from adding water and automatic in emptying.
