A dual volume flow rate switching device. The device comprises a valve body (1), a valve core (2), a spring (3), an inner valve base (5) and an outer valve base (4). The valve core (2) is disposed in and passes through the valve body (1), and an axial liquid channel (23) and a radial liquid channel (24) are disposed in the valve core (2). The axial liquid channel (23) has one end in communication with a water outlet of a tap and the other end in communication with the radial liquid channel (24). An upper sealing member (27) and a lower sealing member (28) are disposed on the valve core (2), and an outlet of the radial liquid channel (24) is located between the upper sealing member (27) and the lower sealing member (28). The outer valve base (4) is disposed at a location corresponding to the upper sealing member (27), and the inner valve base (5) is disposed at a location corresponding to the lower sealing member (28). The spring (3) is sleeved on the valve core (2). A spring base (29) is disposed at the valve core (2) at an upper end of the upper sealing member (27). The spring (3) has one end disposed on the spring base (29) and the other end pressing against an inner side of the valve body (1). The dual volume flow rate switching device has two water outlet channels, provides water at two volume flow rates, and at the same time, is capable of automatically restoring to a small volume flow rate state, thus saving more water resources. |
