Fig. 1 is please referred to, in an embodiment of the present invention, purifier 100 includes concentration water tank 101, with purifier 100
The raw water box 102 of separable setting, water purification component 103 and water purification outlet 104.The raw water box 102 passes through raw water pipeline
20 are connected with water purification component 103, and the concentration water tank 101 is connected by concentrating water lines 10 with water purification component 103, described
Water purification component 103 is connected with water purification outlet 104.The purifier 100 further includes the water level for detecting raw water box 102
First induction part 11, return line 12 and the first valve portion 13 being set on return line 12, the return line 12 connect
Lead to the raw water box 102 and concentration water tank 101, first valve portion 13 is connect with the first induction part 11.First valve
There is changeable opening state and closed state, the first valve portion 13 to detect raw water box 102 in the first induction part 11 in portion 13
Water level is opened when being less than preset value, and the condensed water of concentration water tank 101 is made to flow to raw water box 102.
Wherein, the condensed water for concentrating water tank 101 for storing via the filtering generation of water purification component 103, described first
When valve portion 13 is used in off position, the raw water box 102 and concentration water tank 101 is isolated；First induction part 11 is used for
The water level of raw water box 101 is detected, and when the water level of raw water box 101 is less than a preset value, sends an inductive signal to the first valve
Door portion 13；First valve portion 13 responds the inductive signal and switches to opening state, to allow the condensed water for concentrating water tank 101 can
To flow to raw water box 102 via return line 12.
Specifically, in the present embodiment, when tap water, spring, well water or other water to be filtered are (hereinafter referred to as " former
Water ") when being added to raw water box 102, raw water flows into water purification component 103 via raw water pipeline 20, and water purification component 103 carries out raw water
Filtering, filtered water purification are supplied to user via water purification outlet 104.After raw water is filtered via water purification component 103, water purification
