[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model. Example 1

[0027] like Figures 1-6 As shown, a faucet includes: a faucet housing 101 and a valve core disposed within the faucet housing 101. The valve core includes: a valve seat 102, at least one inlet hole 103 opened on the valve seat 102, an outlet hole 104 opened on the valve seat 102, an outlet pipe 105 disposed on the valve seat 102 and communicating with the outlet hole 104, and an inlet pipe 106 disposed on the valve seat 102 and communicating with the inlet hole 103. A positioning device for positioning the valve core is provided between the faucet housing 101 and the valve seat 102. The positioning device includes: an installation groove 107 opened on the faucet housing 101 corresponding to the valve seat 102, and a sleeve 108 disposed on the valve seat 102 by a fixing device and passing through the installation groove 107. A water-passing device is provided between the sleeve 108 and the valve seat 102.

[0028] To facilitate fixing the sleeve 108 to the valve seat 102 and thus engaging with the faucet housing 101, the fixing device includes at least one locking block 109 disposed on the valve seat 102 via an engaging device, and the sleeve 108 is fixedly connected to the locking block 109.

[0029] To facilitate the connection between the sleeve 108 and the clamp 109, both the sleeve 108 and the clamp 109 are made of metal, and the sleeve 108 is welded to the clamp 109.

[0030] In order to fix the locking block 109 and the sleeve 108 so that they cannot move after being fixedly connected, thereby positioning the sleeve 108, the locking device includes: a positioning groove 110 formed on the valve seat 102 for the locking block 109 to be inserted, a locking groove 112 formed on the valve seat 102 and connected to the positioning groove 110, and a locking block 113 set on the locking block 109 and engaging with the locking groove 112.

[0031] In order to connect the sleeve 108 and the block 109, the upper end of the block 109 is flush with the end of the valve seat 102, and the bottom of the sleeve 108 abuts the end of the valve seat 102.

[0032] In order to control the fluid of the faucet, the water passing device comprises a mounting thread 114 on the sleeve 108, a water passing valve core (not shown) on the valve seat 102 corresponding to the water inlet hole 103 and the water outlet hole 104, and a valve core cover (not shown) locked on the mounting thread 114.

[0033] In order to position the water passing valve core, the valve seat 102 is further provided with a positioning hole 115 for positioning the water passing valve core.

[0034] In order to install the faucet, the bottom of the water inlet pipe 106 is further provided with a mounting seat 116, the mounting seat 116 is provided with a connecting thread 117, and the connecting thread 117 is locked with a faucet mounting pipe (not shown).

[0035] In order to facilitate assembly, the water outlet pipe 105 is further provided with a limiting table 118, and the faucet shell 101 is provided with a limiting ring table 119 matched with the limiting table 118.

[0036] In order to enhance the functionality of the faucet, the water outlet pipe 105 is provided with a faucet rotating part (not shown), and the faucet rotating part is provided with a faucet elbow 120.

[0037] In order to expand the water outlet and facilitate the purchase of the water passing valve core, the water inlet hole 103 is two, and the water inlet pipe 106 is one and simultaneously connected with the two water inlet holes 103.

[0038] The water inlet pipe 106 is further provided with a reinforcing column 111 for enhancing the strength of the valve core body and facilitating the installation in the faucet shell 101.

[0039] Working principle: during assembly, the block 109 is installed through the positioning groove 110 and the clamping groove 112, and then the valve core body is inserted into the faucet shell 101, so that the valve seat 102 is aligned with the mounting groove 107, at this time the sleeve 108 is inserted into the mounting groove 107, so that the bottom of the sleeve 108 abuts the valve seat 102 and the block 109, and then the sleeve 108 and the block 109 are welded together by a welding machine, so that the shell and the valve core body are fixed.

[0040] At this time, the water passing valve core can be installed on the valve seat 102, and the water passing valve core is fixed by the valve core gland. Since the valve core inlet hole 103 and the valve core outlet hole 104 of the water passing valve core are both provided with sealing rings, the fluid cannot contact the welding points and cannot corrode the welding points, thereby ensuring the safety of the fluid and the sealing of the faucet. The welding points are inside the sleeve 108, which greatly enhances the appearance of the faucet and reduces the technical requirements for the welding personnel.

[0041] After the water passing valve core is assembled, the faucet rotating part, the faucet elbow 120 and the faucet mounting pipe can be installed to complete the assembly. During use, the fluid flows from the water inlet pipe 106 into the two water inlet holes 103 connected thereto, flows to the water passing valve core, and finally flows to the water outlet pipe 105 and the faucet elbow 120 through the valve core outlet hole 104 of the water passing valve core to complete the water outlet.
