Aiming at the problems in the related art, the utility model provides a water path system of a clean water dispenser without a built-in pure water tank, which not only can reduce the volume of the clean water dispenser, but also can ensure that the clean water dispenser can quickly filter out pure water under the condition of long-time non-use.
The utility model is realized in the following way:
a water path system of a water purifying and drinking machine without a built-in pure water tank is applied to the inside of the water purifying and drinking machine; comprises a water tank, a first check valve, a self-priming pump and a filter element;
a tap water outlet is arranged on the water tank and is connected with a water inlet end pipeline of the first check valve; the water outlet end of the first check valve is connected with the water inlet end pipeline of the self-priming pump; the first check valve is used for preventing tap water from flowing back to the water tank;

The water tank stores tap water and filtered waste water simultaneously, tap water can be replenished and waste water can be cleaned at any time, and the waste water tank is not required to be placed at a new position for the clean water dispenser or connected to a waste water channel through a pipeline, so that the attractive appearance or the structural volume of the clean water dispenser is influenced.
As a further optimization of the scheme, the wastewater outlet end is sequentially communicated to the concentrated water electromagnetic valve and the wastewater inlet through pipelines. The concentrated water electromagnetic valve pumps the wastewater filtered by the filter element to a wastewater area for storage.
As a further optimization of the scheme, a low water level detector is arranged in the raw water area. When the water level in the original water area is detected to be too low, the alarm can be used for reminding a user to supplement tap water.
