The present invention relates to a pressure boosting showerhead, which consists of a housing, a ball shape connector, a rear holder, an inner holder, a separation header and an water outflow dish. Wherein, a bending second air passage and a second inlet chamber are set between the inner barrel of the rear holder and the cone tip of the inner holder. The second inlet chamber is communicated with the first inlet chamber in the housing. The second inlet chamber is communicated with the mixed chamber of the inner holder through the second air passage, to prevent water flow reversely penetrating into the air circulation path and boost pressure to maintain the water outflow of the showerhead with better impact strength to thereby achieve the purpose of saving water.
