The water outlet pipe and the water inlet pipe are communicated with the first water outlet hole or the second water outlet hole 11, and the first water baffle 7 is arranged at the upper part of the first water outlet hole; the second water baffle 12 is arranged at the upper part of the second water outlet hole 11; the pawl 2 is respectively connected with the pressing device 1 and the ratchet; the ratchet are fixedly arranged on one surface of the rotatable shift disc 4; the damping working surface 5 is vertically arranged on the other surface of the rotatable shift disc 4; the damping working surface 5 is rotationally connected with the first end of the first screw structure 6 or the first end of the second screw structure 10 along with the rotatable shift disc 4; the damping working surface 5 is used to transfer the rotational potential energy of the rotatable shift disc 4 to the first screw structure 6 or the second screw structure 10; the first end of the first torsion spring 8 is connected with the second end of the first screw structure 6, and the first end of the second torsion spring 13 is connected with the second end of the second screw structure 10; the first end of the first torsion spring 8 is also connected with the first water baffle 7; the first end of the second torsion spring 13 is also connected with the second water baffle 12; the first limiting groove 9 and the second limiting groove 14 are correspondingly arranged on both sides of the faucet body; the first torsion spring 8 is arranged in the first limiting groove 9, and the second torsion spring 13 is arranged in the second limiting groove 14; the elastic coefficients of the first torsion spring 8 and the second torsion spring 13 are different.
Delayer 15 is used to set a pre-set delay time; the electromagnetic control device 16 is connected with the pawl 2 and the delayer 15 respectively, and is used for controlling the rotation of the pawl 2 after the delay time elapses, so as to connect the damping working surface 5 with the first end of the first screw structure 6.
Further, FIG. 3 is a schematic structural diagram of the damping working face in the embodiment provided by the present invention. As shown in fig. 3, in this embodiment, the damping working face 5 is arranged at the edge of the rotatable shift disc 4, so that the damping working face 5 can be used to do work on the first screw structure 6 and the second screw structure 10, so that the screw structure can expand and contract in the horizontal direction.
Specifically, when the faucet of this embodiment is in the non-working state, the damping working surface 5 is not connected with the first screw structure 6 and the second screw structure 10; the first torsion spring 8 and the second torsion spring 13 are in a balanced state, with the first water baffle 7 completely closing the first water outlet hole 17 and the second water baffle 12 completely closing the second water outlet hole, that is, there is no water outflow from the outlet tap 3 of the faucet.
The working principle in this embodiment is as follows: as shown in FIG. 2, when the pressing device 1 is pressed for the first time, the pressing device 1 drives the pawl 2 to rotate, and at this time, the ratchet drive the rotatable shift disc 4 to shift gears according to the rotation, and at this time the damping working surface 5 is connected with the first end of the first screw structure 6, and the rotation of the damping working surface 5 can drive the first end of the first screw structure 6 to work; the first screw structure 6 converts the rotational potential energy into axial kinetic energy, so that the first baffle at the second end of the first screw structure 6 moves in the direction of compression of the first torsion spring 8, and at this time, the first water outlet hole 17 is gradually opened, and the water inlet pipe is connected with the water outlet pipe; when the first torsion spring 8 reaches the maximum deformation state, the first water outlet hole 17 is completely opened.
Under the acting force of the first torsion spring 8, the first baffle gradually restores the initial position when it is not working and closes the first water outlet hole 17 again. Due to the large elastic coefficient of the first torsion spring 8, the duration for making the first baffle to restore balance is short, which is used for short-time flushing.
As shown in FIG. 1, when the pressing device 1 is pressed for the second time, the pressing device 1 drives the pawl 2 to rotate continuously, at this time, the ratchets drive the rotatable shift disc 4 to shift gears for the second time according to the rotation, and at this time the damping working surface 5 is connected with the first end of the second screw structure 10, and the second screw structure 10 converts the rotational potential energy into axial kinetic energy. Thus, the second baffle at the second end of the second screw structure 10 moves in the direction of compression of the second torsion spring 13. At this time, the second water outlet hale is gradually opened, and the water inlet pipe is connected with the water outlet pipe. When the second torsion spring 13 reaches the maximum deformation state, the second water outlet hole is completely opened.
Under the acting force of the second torsion spring 13, the second baffle gradually restores the initial position when it is not working and the second water outlet hole is closed again. Because the elastic coefficient of the second torsion spring 13 is small, it takes a long time to make the first baffle to restore balance, which is used for long-term flushing. Thereby realizing the effect of two- gear alternating pressing to adjust the water outlet duration.
Specifically, in this embodiment, the water outlet duration of gear is controlled according to the elastic coefficient of the first torsion spring 8 and the elastic coefficient of the second torsion spring 13. For example, the first torsion spring 8 with appropriate elastic coefficient is selected, using the first gear to meet short-term (about 5 seconds) water demand, such as simply getting your hands wet. The second torsion spring 13 with suitable elastic coefficient is selected, using the second gear to meet the long-term (about 20 seconds) water demand, such washing hands once after using hand sanitizer without pressing many times.
Preferably, the size of the first limiting groove 9 and the size of the second limiting groove 14 are respectively equal to the size of the first torsion spring 8 and the size of the second torsion spring 13, and the first torsion spring 8 and the second torsion spring 13 move horizontally in the first limiting groove 9 and the second limiting groove 14 respectively; when the first torsion spring 8 or the second torsion spring 13 is squeezed and deformed, the second end of the first torsion spring 8 or the second end of the second torsion spring 13 is in contact with the inner wall of the faucet body.
Optionally, the first limiting groove 9 and the second limiting groove 14 can respectively fix the first torque spring and the second torque spring at reasonable positions, thus avoiding the elastic potential energy of the spring from doing ineffective work and ensuring the stability of the faucet's work.
Specifically, the first limiting groove 9 and the second limiting groove 14 can also ensure that the baffle stops moving when the first torque spring and the second torque spring are in the maximum deformation (compression) state, so as to prevent the external force beyond the elastic range from acting on the spring.
Preferably, the size of the first water baffle 7 and the size of the second water baffle 12 are respectively larger than the size of the first water outlet hole 17and the size of the second water outlet hole 11; when the first torsion spring 8 is in a balanced state, the first water baffle 7 closes the first water outlet hole 17; when the first torsion spring 8 is in a maximum deformation state, the first water baffle 7 completely opens the first water outlet hole 17; when the second torsion spring 13 is in a balanced state, the second water baffle 12 closes the second water outlet hole 11; when the second torsion spring 13 is in the maximum deformation state, the second water baffle 12 completely opens the second water outlet hole 11.
As an optional embodiment, the shape of the first water baffle 7 and the shape of the second water baffle 12 may be the same as that of the first water outlet hole 17 and the second water outlet hole 11. Preferably, further comprising: a delayer 15, which is used for setting a pre-set delay time; an electromagnetic control device 16, which is connected with the pawl 2 and the delayer 15 respectively, and is used for controlling the rotation of the pawl 2 after the delay time elapses, so as to connect the damping working surface 5 with the first end of the first screw structure 6. Preferably, the electromagnetic control device 16 includes: a relay, which is connected with the delayer 15, for generating a switching signal according to the delay time; an electromagnetic valve, which is connected with the relay and used for rotatable the pawl 2 according to the switch signal.
In order to ensure that the faucet can be reset to the initial gear position when it has not worked for a long time, the embodiment also discloses a delayer 15, a relay and an electromagnetic valve.
The delay time is set by the delayer 15, for example, the delay time is set to 20 seconds.
Twenty seconds after the end of the water use process in the first or second gear, the relay generates a switch signal, and the electromagnetic valve acts on the pawl 2 according to the switch signal, so that the faucet can be automatically reset to the working state starting from the first gear (water outlet for 5 seconds) at the next startup by the pawl 2. Preferably, further comprising: a waterproof cover, which is used for covering the delayer 15 and the electromagnetic control device 16. Specifically, the electric connecting wires of the delayer 15, the relay and the electromagnetic valve are all covered with waterproof materials to prevent electric leakage.
