The invention discloses negative-pressure-free water supply equipment integrating water purification and water supply. The negative-pressure-free water supply equipment comprises a base and is characterized in that a variable-frequency water feeder is fixedly connected to the upper surface of the base, a cylinder is fixedly connected to the upper surface of the base and located on the left of thevariable-frequency water feeder, a circular pipe is fixedly connected to the top of the inner wall of the cylinder, the water outlet end of the variable-frequency water feeder penetrates the cylinderand is communicated with the circular pipe, a baffle is fixedly connected to the surface of the circular pipe in a sleeved manner and located below the water outlet end of the variable-frequency waterfeeder, the lateral surface of the baffle is fixedly connected with the inner wall of the cylinder, a limit ring is fixedly connected to the inner wall of the circular pipe, a first piston and a filter element are movably connected to the inner wall of the circular pipe and are respectively located right above and right below the limit ring, and a first piston rod is fixedly connected to the upper surface of the first piston. The negative-pressure-free water supply equipment has the advantages that by setting the variable-frequency water feeder, the circular pipe, the filter element and a filter screen, the problem of resource waste caused by the fact that residents independently mount water purification equipment in lives is solved.
