The present utility model will be described in detail with reference to specific embodiments and drawings.

As shown in fig. 1-7 and 10-12, the fagade kitchen faucet comprises a water inlet pipe 100, a valve body 200, a valve core 300 and a water outlet pipe 400. The water inlet pipe is used for connecting and mounting the whole kitchen tap to a tap water pipe arranged on a vertical surface of a cabinet, such as a tap water pipe connected and mounted on the vertical surface of the cabinet.

The water inlet pipe 100 is fixedly connected with the valve body 200 through threads, and a back-locking pressure cap 101 is arranged for the water inlet pipe.

The valve body 200 takes the form of a 90 deg. elbow.

The valve cartridge 300 is assembled to the valve body. The valve cartridge 300, as shown in fig. 5 and 8-9, includes a valve housing 302, a valve stem 301, a first seal 303, a second seal 304, an elastomer 309, and a wear washer 310.

The valve housing 302 is sleeve-shaped, the upper end of the valve housing 302 is fastened to the valve body 200 by threads, and the inner wall of the valve housing 302 is provided with two axial grooves 311. The outer wall of the valve sleeve is sealed with the valve body by a sealing ring sleeved on the outer wall of the valve sleeve, so that water flow is prevented from flowing along the axial direction between the outer wall of the valve sleeve and the valve body.

The valve stem 301 is rod-shaped and extends downwardly from the interior of the valve housing 302, and the valve stem 301 is sealed against the interior wall of the valve housing 302 by a sealing ring that is fitted over the valve stem to prevent water flow in the axial direction between the valve stem 301 and the interior wall of the valve housing 302. The upper end of the rod 301 has two dial posts 312.

The first seal 303 has two bore-like first passages 305, two fan-shaped first sealing surfaces 306 and two axial ribs 313, the axial ribs 313 being located in corresponding axial grooves 311 such that the first seal 303 fits into the valve housing 302 and cannot rotate.

The second seal 304 has two notched second channels 307, two fan-shaped second sealing surfaces 308 and two slots 314. Insertion of the shift posts 312 into the corresponding slots 314 causes the valve stem 301 to be assembled with the second seal 304, with the valve stem 301 rotating with the second seal 304.

Rotation of the second seal 304 causes the first channel 305 to communicate with the second channel 307 to open the faucet or the first channel 305 is offset from the second channel 307 and blocked by the first sealing surface 306 and the second sealing surface 308 to close the faucet. Thus, the faucet can be opened by rotating the valve stem with the second seal member to rotate relative to the first seal member to open the faucet or to close the faucet. Wherein the water flow path comprises a first path of the first seal and a second path of the second seal, the flow direction of the water being indicated in fig. 4-5 by the dashed lines of the identified arrows.

The elastic body 309 is an elastic sleeve closely attached to the inner hole at the upper end of the valve sleeve 302, the elastic sleeve is pressed between the upper end surface of the valve sleeve and the valve body 200 to fix and seal the valve sleeve and the valve body, and the elastic body 309 abuts against the upper side surface of the first sealing element 303 to exert elastic force on the first sealing element. A wear washer 310 is placed over the valve stem 301 and axially between the valve stem 301 and the valve sleeve 302, the wear washer 310 isolating the valve stem 301 from the valve sleeve 302 to increase the wear resistance of the valve stem 301 to rotation relative to the valve sleeve 302. The elastic force of the elastomer urges the first sealing surface 306 of the first seal against the second sealing surface 308 of the second seal.

The water outlet pipe 400 has a sleeve 401 and a flow tube 402 connected to one end of the sleeve. The sleeve is preferably attached to one end of the flow tube by welding. In the illustrated construction, the other end of the flow tube 402 is connected in intersection with a water outlet tube 405 which is closed at one end and houses a bubbler 406 in the other end. It is readily contemplated that in other constructions, the flow tube may be an elbow and the bubbler may be mounted directly to the other end of the flow tube.

The sleeve 401 is sleeved outside the valve core 300, specifically, the sleeve 401 is sleeved outside the valve sleeve 302, so that the whole water outlet pipe can rotate relative to the valve core. The inner wall of the sleeve 401 and the outer wall of the valve housing 302 are sealed by a sealing ring sleeved on the outer wall of the valve housing 302 to prevent water flow between the inner wall of the sleeve 401 and the outer wall of the valve housing 302 along the axial direction. The inner wall of the lower end of the sleeve 401 is provided with a positioning groove 404.

As shown in fig. 2, the flow tube 402 and the valve body 200 have a portion H overlapping each other in the axial direction of the valve stem. When the water outlet pipe 400 rotates, the flow pipe is abutted against the valve body by the overlapped part and positioned by the valve body. Specifically, a first intersecting edge line 201 which is anastomotic with the outer wall of the sleeve is arranged on the valve body, the flow pipe and the sleeve are intersecting and connected with a second intersecting edge line 403, and when the water outlet pipe rotates, the position of the second intersecting edge line on the flow pipe is abutted against the position of the first intersecting edge line on the valve body and is positioned by the valve body.

Furthermore, the valve rod 301 extends downward, the lower end of the sleeve 401 is provided with a sealing cover 501 rotating along with the sleeve, the sealing cover 501 is square, and corners of the sealing cover 501 are placed in corresponding positioning grooves 404 so that the sealing cover can rotate along with the sleeve. The cap 501 fits over the valve stem 301 and fits with the spline 315 on the valve stem 301 so that the cap can rotate with the valve stem. The valve rod 301 is sleeved with a cover plate 502 positioned on the lower side of the sealing cover, the end part of the valve rod 301 is connected with a nut 503, the nut 503 presses the cover plate 502 on the lower end face of the sleeve 401, and the sealing cover 501 is limited on the lower end of the sleeve by the cover plate 502.

Therefore, by rotating the water outlet pipe 400, the valve rod 301 can be rotated, and then the second sealing member can be rotated relative to the first sealing member to open or close the faucet, and meanwhile, the rotation range of the water outlet pipe is positioned by the valve body instead of the valve core, so that the valve core is prevented from being damaged due to larger impact.

As shown in fig. 12, the water outlet pipe 400 is configured to be a water outlet position at a middle position of its rotation range (a water outlet pipe position expressed by a solid line outline shown in the drawing), to be positioned at both end positions of its rotation range, and to be a closed position (a water outlet pipe position expressed by a broken line outline). And an included angle beta of 90+/-10 degrees is kept between the water outlet position of the water outlet pipe and any closing position of the water outlet pipe. When the water outlet pipe 400 is rotated rightward from the water outlet position shown in fig. 12, the state shown in fig. 10 can be reached to be positioned. When the water outlet pipe 400 is rotated leftwards from the water outlet position shown in fig. 12, the state shown in fig. 11 can be reached to be positioned.
