Detailed Description

The technical solution of the present invention is further illustrated by the following embodiments and accompanying drawings.

Fig. 1 is a schematic structural diagram of a faucet according to an exemplary embodiment of the present application. As shown in fig. 1, the faucet includes: outlet conduit 1, switch handle 2, first valve body 3 and second valve body 4, outlet conduit 1 includes delivery port 13 and the branch road 12 that links to each other with delivery port 13.

The first valve body 3 is assembled in the water outlet pipe 1 and comprises a first valve core 31 and a torsion spring 32, the torsion spring 32 is respectively matched with the switch handle 2 and the switch of the first valve core 31, when the switch handle 2 is rotated along the circumferential direction of the torsion spring 32, the torsion spring 32 is compressed by force, and the switch of the first valve core 31 is pushed to an opening position; when the acting force on the switch handle 2 disappears, the torsion spring 32 gradually resets to push the switch of the first valve core 31 to the blocking position.

The second valve body 14 is assembled in the branch 12 and includes a second valve core 41 and a linkage 42, and the linkage 42 is respectively engaged with the switch handle 2 and the switch of the second valve core 41. When the switch handle 2 is pulled in a first direction along the axial direction of the torsion spring 32, the linkage 42 pushes the switch of the second valve core 41 to the open position; when the switch handle 2 is pulled in a second direction opposite to the first direction, the linkage 42 drives the second valve core 41 to open and close to the blocking position.

By providing the tap with a first valve body 3 and a second valve body 4, and by arranging the first valve body 3 in the water outlet conduit 1, the second valve body 4 is arranged in a branch 12 communicating with the water outlet 13 and being in parallel with the water outlet conduit 1. Wherein, the switch handle 2 of the faucet rotates along the circumference of the torsion spring 32 to make the first valve body 3 realize time-delay switch, namely the switch handle 2 of the faucet can reset and close automatically after opening, thus improving the water-saving performance of the faucet. In addition, the switch handle 2 of the faucet can be pushed and pulled along the axial direction of the torsion spring 32 to switch the second valve body 4, namely, the frequency of operating the switch handle 2 is reduced when long-time water consumption is needed, so that the faucet has the use convenience under the condition of two kinds of water consumption.

The torsion spring 32 may be disposed in a lateral or longitudinal direction. Wherein, the longitudinal direction is parallel to the direction of water flow at the water outlet 13, and the transverse direction is perpendicular to the longitudinal direction. The torsion spring 32 is longitudinally arranged, so that the torsion spring 32 can be compressed by the torsion force in the horizontal direction, the first valve core 31 is in an open state, and the convenience of a user in operating the faucet switch handle 2 is improved. After the torsional force applied to the switch handle 2 by the user disappears, the torsion spring 32 automatically resets to drive the switch handle 2 to rotate back to the initial position, so that the first valve core 31 is in a closed state, and the water tap does not discharge water any more. The user only needs to rotate the switch handle 2 once, and the water tap automatically realizes the delayed water closing, thereby avoiding the situation of forgetting to close the water tap and improving the water-saving effect.

The water tap further comprises at least one first sealing element 5, wherein the first sealing element 5 is arranged between the water outlet pipeline 1 and the first valve body 3 or/and the branch 12 and the second valve body 4. The arrangement of the first sealing element 5 improves the sealing performance of the water faucet 1 during water supply, avoids water flow from flowing out from a gap between the first valve body 3 or the second valve body 4 and the water outlet pipeline 1, and further ensures water saving performance. The first sealing member 5 may be a rubber ring, or may be a sealing structure made of other materials, which is not limited in the present application.

In another embodiment of the present application, as shown in fig. 2, the faucet further includes an auxiliary conduit 6, the auxiliary conduit 6 is made of a flexible material, the auxiliary conduit 6 is sleeved on the outside of the water outlet conduit 1, the auxiliary conduit 6 is movably connected to the water outlet conduit 1, and the free end 61 of the auxiliary conduit 6 is detachably connected to the water outlet 13 of the water outlet conduit 1. When the free end of the auxiliary pipeline 16 is detached from the water outlet 113 of the water outlet pipeline 11, the auxiliary pipeline 16 movably connected with the water outlet pipeline 11 is pulled to prolong the water outlet position of the water faucet 1, so that objects far away from the water faucet 1 can be cleaned conveniently, the auxiliary pipeline 6 is sleeved outside the water outlet pipeline 1, the pollution to water flow inside the water outlet pipeline 1 when the auxiliary pipeline 6 is retracted after being used can be avoided, and the water supply sanitation is improved.

In yet another embodiment of the present application, as shown in FIG. 3, the auxiliary conduit 6 is disposed inside the outlet conduit 1, which can increase the exterior aesthetics of the faucet when the auxiliary conduit 6 is disposed inside the outlet conduit 1.

The faucet further comprises an elastic resetting piece, wherein the elastic resetting piece is connected with the auxiliary pipeline 6 and pulls the free end 61 of the auxiliary pipeline 6 to prolong the water outlet position of the faucet. After the pulling force of the free end 61 of the auxiliary pipeline 6 disappears, the elastic resetting piece pulls the auxiliary pipeline 6 to reset to the initial position, so that the use and storage convenience of the auxiliary pipeline 6 are improved. It should be noted that the elastic restoring member may be an elastic member such as a spring, rubber, etc., and the application does not limit the specific structure of the elastic restoring member.

The water faucet further comprises a second sealing element 7, wherein the second sealing element 7 is arranged between the free end 61 of the auxiliary pipeline 6 and the water outlet 13, so that water flow is prevented from flowing out of a gap between the auxiliary pipeline 6 and the water outlet 13, and the sealing effect and the water saving performance are improved.

According to the application, a water supply system is provided, which comprises the water tap.
