Abstract

The utility model discloses a water purifier. The barrel body is formed by the connection of an upper barrel and a lower barrel. The barrel is provided with a front filter core and a lower filter core therein. The lower filter core includes a lower filter core shell. The lower filter core shell which is arranged at the lower part of the lower otter board of the lower filter core is connected with a lower shell which is connected with a lower filter core inner shell where a hydrophilic membrane is arranged. The front filter core includes a front filter core shell, the middle part in which a central tube is arranged. The bottom of the front filter core shell has a splint, the upper part of which is provided with an upper otter board and a front filter core lower otter board respectively. The characteristic is that, the upper end of the central tube is provided with an exhaust unit composed of an exhaust ball and an exhaust cap of the upper part of the exhaust ball. The exhaust unit, which is composed of an exhaust ball and an exhaust cap of the upper part of the exhaust ball, is arranged above the centre of the filter core bowl of the lower filter core. An exhaust duct which is communicated with the exhaust unit of the lower filter core is provided within the upper barrel. The utility model has advantages of no gas resistance, pleasant drainage of water purifier, and easy using.
