An inner cavity 901 is provided inside the rubber ring 9, and the inner cavity 901 is sealed with the spherical head 604 at the bottom of the rotating body 6. The rubber ring 9 is made of EPDM material.

[0032] When installing the ball head assembly 105, first install the small O-ring 5 into the two inner grooves 603 on the upper part of the rotating body 6, then install the pressure cap 8 on the upper part of the spherical head 604 of the rotating body 6 and press it tightly, so that the contraction area 801 shrinks inward, and the outer diameter of the upper boss 802 becomes smaller, so that the pressure cap 8 can be easily installed inside the pressure cap 7; then install the pressure cap 8 and the spherical head 604 together into the pressure cap 7, and ensure that the upper boss 802 is close to the upper part of the pressure cap 7, and finally install the rubber ring 9 into the inner cavity 702 of the pressure cap 7. Among them, the pressure cap 8 and the rubber ring 9 are both installed inside the pressure cap 7 so that the two share a cavity design, which reduces the production cost and makes assembly more convenient. In addition, the rotating body 6 eliminates the hidden danger of water leakage under the action of the pressure cap 8 and the rubber ring 9, and the inner cavity 702 provided inside the pressure cap 7 effectively prevents the potential risk of the rubber ring 9 falling off during assembly.

[0033] After the ball head assembly 105 is assembled, it can be locked with the internal thread at the water outlet end of the base 106 through the external thread surface 703 of the pressure cap 7. After installation, the pressure cap 7, the pressure cover 8, and the rubber ring 9 in the ball head assembly 105 are all built into the base 106, and the rotating body 6 can rotate freely inside the pressure cover 8 and the rubber ring 9, thereby driving the overall water outlet assembly 1 to rotate freely, and the user can adjust the tightness through the rotating hole 701 on the pressure cap 7 according to the need of hand feel or fixed position, that is, rotating the screw can squeeze the pressure cover 8 downward to lock the spherical head 604. After locking, the water outlet assembly 1 can be guaranteed to be fixed at a required position, thereby realizing stepless adjustment of the water spout of the washbasin in the left, right, up and down directions.

[0034] When the wash basin of the utility model is used after installation, the cold and hot water first enter the PPR valve body assembly 4, and the cold and hot water ratio is adjusted by the water flow control element A, and then enter the base 106 through the internal adapter, and then enter the ball head assembly 105, and then enter the water outlet 104 and the water outlet head 102 in sequence, and finally flow through the bubbler 101 for the user to use, and can be adjusted to any position steplessly. In this process, the user can lift the water outlet assembly and rotate it upward at 45 degrees, so as to achieve daily hair washing or water collection with a bucket, such as Figure 8 and Fig. 9 As shown; you can also turn the basin left and right to clean it, saving space. Turning left and right can also avoid the problem of obstacles around causing the faucet to be unable to be installed; you can also return it to its original position after use, or fold the water outlet assembly 1 close to the wall. The folding design makes the wash basin have more usable space, such as Fig.10 In summary, the design of the utility model makes the entire wash basin faucet more beautiful in appearance, and can also adjust the water outlet angle in multiple dimensions, and the multi-angle water outlet is more applicable.
