Abstract

The present invention discloses a multifunctional faucet and a stove cabinet using the faucet. The multifunctional faucet includes a mixing faucet, a cylinder installed on the upper part of the mixing faucet, a ceramic filter installed in the cylinder, a brush assembly installed between the cylinder and the ceramic filter, a connecting sleeve fixedly connected to the upper end of the cylinder, and a water outlet assembly installed at the upper end of the connecting sleeve. Since the ceramic filter is installed in the drinking water outlet joint through a right-handed thread, the upper latching teeth and the lower latching teeth are respectively one-way latching teeth with tooth surfaces facing counterclockwise, so that the filter element joint of the ceramic filter element will not be separated from the drinking water joint. Due to the presence of the roller, the scrubbing plate is kept at an appropriate distance from the inner wall of the ceramic filter element, so that the scrubbing head can be kept in an extended state, thereby ensuring a scrubbing effect. Since the water outlet pipe is rotated according to usage needs during use, the outer wall of the ceramic filter element can be automatically cleaned without specially cleaning the outer wall of the ceramic filter element.
