[0039] 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

[0040] like Figures 1-9 As shown, a leak-proof shower faucet includes: an inner core, the inner core including: a valve seat 101, at least one water inlet hole 102 and water outlet hole 103 opened on the valve seat 101, a water inlet pipe 104 and a water outlet pipe 105 disposed on the valve seat 101 and connected to the water inlet hole 102 and the water outlet hole 103, the water inlet pipe 104 being provided with a water inlet seat 106 for connecting to a water supply pipe via a quick-release device;

[0041] To facilitate connection with water supply pipes, the axial direction of the water inlet seat 106 is generally different from the axial direction of the water inlet pipe 104.

[0042] To facilitate the installation of the water inlet seat 106, the quick-release device includes: a connecting pipe 107 disposed on the water inlet seat 106 for connecting the water inlet seat 106 and the water inlet pipe 104; a mounting seat 108 disposed on the water inlet pipe 104; a locking device is provided between the mounting seat 108 and the connecting pipe 107; and a sealing device is also provided between the connecting pipe 107 and the mounting seat 108.

[0043] To prevent the connecting pipe 107 from detaching from the mounting base 108, the engaging device includes: at least one insertion groove 109 formed on the mounting base 108, a rotating groove 110 formed on the mounting base 108 and communicating with the insertion groove 109, and an engaging block 111 provided on the connecting pipe 107 for engaging with the rotating groove 110.

[0044] To enhance the stability of the connection between the connecting pipe 107 and the mounting base 108, the mounting base 108 is also provided with a limiting platform 112 that abuts against the end of the connecting pipe 107.

[0045] To prevent the connecting pipe 107 from rotating easily after installation, the rotating groove 110 is also provided with an anti-disengagement groove 113 that matches the locking block 111;

[0046] The size of the rotating groove 110 is slightly smaller than that of the locking block 111. However, both the mounting base 108 and the connecting pipe 107 are made of materials with a certain degree of elasticity, such as plastic. Therefore, when the locking block 111 rotates, the rotating groove 110 will undergo a partial deformation. When the locking block 111 rotates into the anti-disengagement groove 113, the rotating groove 110 will return to its original state, thereby preventing the locking block 111 from easily disengaging from the anti-disengagement groove 113.

[0047] To prevent fluid leakage, the sealing device includes: a plurality of first sealing grooves 114 formed on the connecting pipe 107, and a first sealing ring fitted on the first sealing grooves 114.

[0048] To protect the inner core, the valve seat 101 is also provided with a faucet housing 116 for protecting the inner core via a positioning device.

[0049] To position the inner core and the faucet housing 116, the positioning device includes: a slot 117 formed on the faucet housing 116 for inserting the inner core; a valve core mounting seat 118 set on the faucet housing 116 corresponding to the valve seat 101; the bottom of the valve seat 101 abuts against the faucet housing 116; a valve core cover 119 for positioning the valve core (not shown in the figure) and the inner core is locked on the valve core mounting seat 1181; and a water outlet device is also provided between the faucet housing 116 and the inner core.

[0050] To facilitate connection to the shower head or direct water flow and prevent fluid from flowing into the housing, the water outlet device includes: a water outlet 120 on the faucet housing 116 corresponding to the water outlet pipe 105, and a water outlet nut 121 locked on the water outlet pipe 105. The water outlet nut 121 passes through the water outlet 120 and is connected to the water outlet pipe 105.

[0051] In order to further locate the inner core and simplify the production process of the water inlet seat 106, the faucet housing 116 is also provided with a first threaded seat 122. The first threaded seat 122 is provided with a relief groove 123 for avoiding the water inlet pipe 104. The water inlet seat 106 is located inside the first threaded seat 122.

[0052] To facilitate the installation of the union nut and the corresponding sealing ring, a limit block 124 is also provided on the water inlet seat 106, and a second sealing ring (not shown in the figure) is also provided on the water inlet seat 106 to abut against the union nut.

[0053] To enhance the strength of the faucet housing 116, a number of reinforcing ribs 125 are provided on the faucet housing 116 to enhance its strength.

[0054] To prevent the faucet housing 116 from expanding under stress and affecting the sealing performance, and to facilitate assembly, there are at least four reinforcing ribs 125, which are located on the upper and lower sides inside the faucet housing 116 respectively. The reinforcing ribs 125 are also provided with locking blocks 126, and a tensioning device is provided between the locking blocks 126.

[0055] The tensioning device includes a pull plate 127, which covers the reinforcing ribs 125 located on the upper and lower sides of the faucet housing 116 and has a locking hole 128 corresponding to the locking block 126. The pull plate 127 is made of metal and has stronger strength than plastic.

[0056] In order to protect the inner core and prevent foreign objects from entering the faucet housing 116, the faucet housing 116 is also provided with a cover plate 129, and the cover plate 129 is also provided with a clearance opening 115 corresponding to the first threaded seat 122.

[0057] To facilitate subsequent assembly steps, a second threaded seat 130 is also provided on the first threaded seat 122, and a through hole 131 matching the second threaded seat 130 is provided on the cover plate 129.

[0058] To enhance the functionality of the faucet and enable it to output hot and cold water, there are two water inlet holes 102, and the water inlet pipe 104 is configured to match the water inlet holes 102. The valve core on the valve seat 101 is a hot and cold water mixing valve core.

[0059] Working principle: During assembly, the connecting pipe 107 is inserted into the mounting base 108 and rotated to engage the locking block 111 with the anti-disengagement groove 113. At this time, the inner core can be placed into the faucet housing 116. Then, the pull plate 127 is installed on the locking block 126, and the cover plate 129 is positioned by screws. At this time, the inner core and the valve core can be positioned by the valve core cover 119. Due to the action of the pull plate 127, the faucet housing 116 will not be forced open when the valve core is installed.

[0060] In use, the fluid flows from the water supply pipe to the water inlet seat 106, then to the water inlet pipe 104, and then into the water inlet hole 102. Finally, it flows through the valve core to the water outlet hole 103 to complete the water discharge. Example 2
