Abstract

A two-mode switchable shower head and its switching method are provided. The shower head includes a water outlet unit (100), a sliding unit (200) and two water outlet mechanisms. The water outlet unit (100) has a main water channel, two branch water channels and a sliding channel which locates between the main water channel and the two branch water channels and communicates with them. The sliding unit (200) can slide along the direction perpendicular to the water outlet unit (100) and can slide between the first position and the second position. The sliding unit (200) includes a main seat (210) and two secured bars (220). The two secured bars (220) respectively seals and protrudes from the water outlet unit (100), so that the user can control the sliding unit (200) and select it to be on the first position or the second position. The main seat (210) is provided with an accommodating cavity (211) opening to the branch water channels and a water pressure channel (212) opening to the main water channel and being communicated with the accommodating cavity (211). The inside of the accommodating cavity (211) is accommodated with a rubber ball (260). When the sliding unit (200) is on the first position, due to the water pressure the rubber ball (260) abuts against and seals the first branch water channel, and the main water channel communicates with the second branch water channel. When the sliding unit (200) is on the second position, due to water pressure the rubber ball (260) abuts against and seals the second branch water channel, and the main water channel communicates with the first branch water channel.
