The shell (10) has a partition therein, and a connecting hole (11) axially penetrates through the partition. The control sleeve (20) has an outer thread section (21) which is engaged with the connecting hole (11) to secure the control sleeve (20) with the shell (10). The control sleeve (20) comprises an axle hole (22) at one end, and at least a first flow hole (23) is formed around the axle hole (22), and at least a locating portion (24) protrudes from the other end of the control sleeve (20). The connecting sleeve (30) has a tube portion (31) at one end, and an inner thread section (32) is formed at the other end of the connecting sleeve (30), and at least an O-ring (33) is disposed on the tube portion (31). The connecting sleeve (30) is inserted into the control sleeve (20) through the tube portion (31), and the O-ring (33) is abutted against an inner periphery of the control sleeve (20) to achieve the leakproof effect. Moreover, at least a recess (34) is formed on an outer periphery of the connecting sleeve (30), and the locating portion (24) is coupled in the recess (34) to secure the position of the control sleeve (20) and the connecting sleeve (30). The tube portion (31) comprises an axial rod hole (311) formed at a central portion thereof, and a plurality of second flow holes (312) are formed around the rod hole (311). Furthermore, the connecting sleeve (30) has a water-stop ring (35) formed between the rod hole (311) and the inner thread section (32). The water-stop unit (40) comprises a front rod (41), a water-stop plug (42), and a rear rod (43) formed sequentially, and the front rod (41) of the water-stop unit (40) is adapted to penetrate through the axle hole (22) and the rod hole (311) so as to locate the water-stop plug (42) in the connecting sleeve (30). In addition, the front rod (41) is engaged with a nut (44) at a front end after penetrating through the axle hole (22). Also, a first spring (45) and a second spring (46), which are disposed on the front rod (41), are respectively coupled between the nut (44) and the control sleeve (20) and between the water-stop plug (42) and the connecting sleeve (30). Furthermore, the first spring (45) and the second spring (46) have the same elastic force, and the nut (44) is adapted to be locked so as to increase the resilience of the first spring (45). The locating unit (50) has an axial sliding hole (51) at a central portion thereof, and the locating unit (50) is disposed on the rear rod (43) through the sliding hole (51), and a plurality of supporting legs (52) protrude from an outer periphery of the locating unit (50). The locking tube (60) is engaged with the inner thread section (32) of the connecting sleeve (30), and the supporting legs (52) of the locating unit (50) is secured between the locking tube (60) and the connecting sleeve (30).
(13) Structurally, referring to FIGS. 2 and 3, the second spring (46) is disposed on the front rod (41) of the water-stop unit (40), and the front rod (41) penetrates through the connecting sleeve (30) from the end having the inner thread section (32), and the front rod (41) penetrates through the rod hole (311) of the tube portion (31). The water-stop plug (42) is positioned in the connecting sleeve (30), and the second spring (46) is coupled between the connecting sleeve (30) and the water-stop plug (42). The O-ring (33) is disposed on the tube portion (31), and a front end of the tube portion (31) is inserted into the control sleeve (20). Moreover, the O-ring (33) is abutted against the inner periphery of the control sleeve (20), and the locating portion (24) is slidably coupled in the recess (34) of the connecting sleeve (30). The front rod (41) is configured to penetrate through the axle hole (22) of the control sleeve (20), and the first spring (45) is disposed on the front rod (41). Then, the nut (44) is locked on the front rod (41) so as to couple the first spring (45) between the nut (44) and control sleeve (20). The locating unit (50) is coupled in the connecting sleeve (30) at the end having the inner thread section (32), and the sliding hole (51) is disposed on the rear rod (43) of the water-stop unit (40). The locking tube (60) is engaged with the inner thread section (32) of the connecting sleeve (30), and the supporting legs (52) are secured between the locking tube (60) and the connecting sleeve (30). After the control sleeve (20), the connecting sleeve (30), the water-stop unit (40), the locating unit (50), and the locking tube (60) are assembled together, the shell (10) is coupled therearound, and the connecting hole (11) is engaged with the outer thread section (21) of the control sleeve (20), thereby completing the assembly.
(14) In actual application, referring to FIGS. 2 to 4, the control sleeve (20) is sleeved on the tube portion (31) of the connecting sleeve (30), such that the control sleeve (20) and the connecting sleeve (30) are slidable to change the relative position. The front rod (41) of the water-stop unit (40) penetrates through the axle hole (22) of the control sleeve (20), and the first spring (45) and the nut (44) are disposed on the front rod (41) to limit the position of the control sleeve (20) while the second spring (46) and the water-stop plug (42) are adapted to limit the position of the connecting sleeve (30) so as to enable the control sleeve (20) and the connecting sleeve (30) to be not detached from each other. Moreover, the first spring (45) and the second spring (46) are configured to form reciprocal spring forces, such that when one end of the locking tube (60) is locked on the connecting sleeve (30) and the other end thereof is connected to a water outlet tube (A) on a wall, the control sleeve (20) abutted by the first spring (45) is adapted to be moved toward the rear direction, and the shell (10) secured with the control sleeve (20) is driven and abutted against the wall, thereby achieving the automatic adjustment of assembly position for the shell (10).
(15) Furthermore, referring to FIGS. 2 to 6, before used, the end at the locking tube (60) has no water pressure, and the first spring (45) and the second spring (46) providing the reciprocal spring forces are adapted to keep the water-stop unit (40) in the conducting position that the water-stop plug (42) is not abutted against the water-stop ring (35) of the connecting sleeve (30). Thus, water is configured to flow from the water outlet tube (A) through the second flow holes (312) of the connecting sleeve (30) and the first flow hole (23) of the control sleeve (20), and flow out of the faucet only from a front end of the shell (10), thereby preventing water coming out from a shower head incautiously. When water needs to come out from the shower head, a user only need to pull the shell (10) in the direction away from the connecting sleeve (30), and the shell (10) is configured to drive the control sleeve (20) to press the first spring (45), and the water-stop plug (42) of the water-stop unit (40) is driven to move toward the water-stop ring (35) of the connecting sleeve (30) so as to stop water flowing from the front end of the shell (10) and enable the water pressure to press on the water-stop plug (42). When the user releases the shell (30), the first spring (45) is adapted to pull the shell (10) back to its initial position, and the elastic force of the first spring (45) together with the water pressures is provided to withstand the elastic force of the second spring (46) so as to keep the water-stop plug (42) at the water-stop position and to enable water to flow out from the shower head. When water is turned off, the water pressure on the water-stop plug (42) is disappeared, and the first spring (45) and the second spring (46) are adapted to push the water-stop unit (40) back to its initial position, and water is adapted to come out from the faucet when used next time so as to prevent the user from getting wet in case that water suddenly comes out from the shower head. Notably, the movements of the water-stop unit (40) and the shell (10) are achieved through the cooperation of the first spring (45) and the second spring (46), which effectively improves the use stability and durability of the faucet. More specifically, the user can pull the shell (10) to switch water flow from the faucet or the shower head, and the first spring (45) and the second spring (46) are configured to cooperately move the shell (10) back to its initial position when the shell (10) is released so as to prevent the situation of switching water flow due to accidental touch, thereby enhancing the practicality of the faucet.
(16) Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
