#This application claims priority to Chinese Patent Application 201910193329.7, filed on Mar. 14, 2019, which is incorporated herein by reference.

#The present disclosure relates to a fixed portion in the sanitary field, and in particular relates to a socket device having a water passage switching function.

#A traditional sanitary device, such as a household shower, comprises a switching valve, a fixed shower, a handheld shower, and a fixed portion. The switching valve has a water inflow passage and two outflow passages. The two outflow passages are respectively connected to the fixed shower and the handheld shower. The switching valve controls the fixed shower head or the handheld shower to discharge water. The fixed portion comprises a plug portion in which the handheld shower is inserted. The shower has the following shortcomings: 1. the switching valve and the fixed portion are separate, thereby occupying a large amount of space and making the shower inconvenient to install, and 2. it is necessary to manually control the waterway switching, which is inconvenient to use.

#The present disclosure will be further described below with the combination of the accompanying drawings and the embodiments.

#FIG. 1 illustrates a perspective view of a socket device of Embodiment 1 of the present disclosure.

#FIG. 2 illustrates a first exploded perspective view of the socket device of Embodiment 1 of the present disclosure.

#Referring to FIGS. 1-12B, a socket device comprises a fixing portion 10. The fixing portion 10 comprises a socket portion 20, a water inflow passage 30, a first water outflow passage 40, a second water outflow passage 50, a first switching mechanism 60, a first water dividing passage 70, and a first control mechanism 80. The socket portion 20 comprises a switch 200. The first switching mechanism 60 is connected to the water inflow passage 30, the first water outflow passage 40, and the second water outflow passage 50. The first water outflow passage 40 and the second water outflow passage 50 are switched to be connected to the water inflow passage 30 by the first switching mechanism 60. The switch 200 is connected to the first switching mechanism 60 to drive the first switching mechanism 60 to enable switching when a handheld assembly is inserted into the socket portion 20 or the handheld assembly is pulled out from the socket portion 20. The first water dividing passage 70 is connected to the water inflow passage 30 and the first water outflow passage 40. The first control mechanism 80 is configured to control the water inflow passage 30 to be connected to the first water dividing passage 70 or control the first water dividing passage 70 to be opened and to be closed. That is, there are two water outflow modes of the first water outflow passage 40. In a first water outflow mode of the two water outflow modes, the first water outflow passage 40 is switched to be connected to the water inflow passage 30 by the first switching mechanism 60. At this time, water flowing from the water inflow passage 30 directly flows into the first water outflow passage 40 and flows out from the first water outflow passage 40. If the first water outflow passage 40 is connected to a handheld shower, water flows out from the handheld shower. In a second water outflow mode of the two water outflow modes, the first control mechanism 80 is opened to be connected to the water inflow passage 30. At this time, water flowing from the water inflow passage 30 flows into the first water outflow passage 40 through the first water dividing passage 70, water flows through the water inflow passage 30, the first water dividing passage 70, and the first water outflow passage 40, and flows out from the handheld shower.

#The first switching mechanism 60 comprises a first sliding portion 61 and a first sealing ring 62. The first sliding portion 61 is slidably disposed in the fixing portion 10, and the first sealing ring 62 is fixedly disposed on the first sliding portion 61. A first inlet 41 of the first water outflow passage 40 and a second inlet 51 of the second water outflow passage 50 are disposed at intervals and face each other. The water inflow passage 30 is disposed between the first inlet 41 and the second inlet 51. The first sealing ring 62 is disposed between the first inlet 41 and the second inlet 51 and corresponds to the first inlet 41 and the second inlet 51. When the first sealing ring 62 seals one of the first inlet 41 or the second inlet 51, the other of the first inlet 41 or the second inlet 51 is connected to the water inflow passage 30. That is, when one of the first inlet 41 of the first water outflow passage 40 or the second inlet 51 of the second water outflow passage 50 is closed, the other of the first inlet 41 of the first water outflow passage 40 or the second inlet 51 of the second water outflow passage 50 is connected to the water inflow passage. That is, the first sliding portion 61 slides to drive the first sealing ring 62 to move to be seal with one of the first inlet 41 or the second inlet 51. In this way, the first water outflow passage 40 and the second water outflow passage 50 are switched to be connected to the water inflow passage 30 due to a sliding movement of the first sliding portion 61. In a specific structure, the first sliding portion 61 comprises a sliding bar 613, and a middle portion of the sliding bar 613 comprises a ring shoulder 611 extending outward. The ring shoulder 611 comprises an assembly groove 612 extending inward. The first sealing ring 62 is fixedly disposed in the assembly groove 612.

#A structure of the socket portion 20 is, for example, a C-shaped structure or a sleeved structure, and the structure of the socket portion 20 is conventional. The switch 200 comprises a movable member 21 movably connected to the socket portion 20, and the movable member 21 is drivably connected to the first sliding portion 61 of the first switching mechanism 60. When the handheld assembly is inserted into the socket portion 20, or when the handheld assembly is pulled out from the socket portion 20, the movable member 21 moves relative to the socket portion 20 to trigger the first sliding portion 61 to slide. The handheld assembly is, for example, a handheld shower. A first elastic body 12 is disposed between the first sliding portion 61 and the fixing portion 10. The first elastic body 12 accumulates energy when the handheld assembly is inserted into the socket portion 20, and the first elastic body 12 releases the energy to reset the first switching mechanism 60 when the handheld assembly is pulled out from the socket portion 20. In the embodiment, the movable member 21 is swingably connected to the socket portion 20, and the movable member 21 abuts the first sliding portion 61 to push the first sliding portion 61 to slide. For example, the socket portion 20 defines a socket space 22. The movable member 21 moves relative to the socket portion 20 between a pull-out position or an inserted position. When the movable member 21 is at the pull-out position, the movable member 21 at least partially protrudes into the socket space 22. The movable member 21 is triggered, for example, firstly, when the handheld assembly is inserted into the socket portion 20, the handheld assembly triggers the movable member 21, a second end of the movable member 21 moves away from the socket space 22, secondly, when the handheld assembly is pulled out from the socket portion 20, the second end of the movable member 21 moves towards the socket space 22 to protrude into the socket space 22. Preferably, a push block 11 is slidably connected to the fixing portion 10, and the push block 11 abuts between the first sliding portion 61 and the movable member 21. In a specific structure, a first end of the movable member 21 comprises a connecting portion 2110, and the connecting portion 2110 comprises a hook 211 comprising an opening 2112 and a body 2111. A size of the opening is smaller than a size of the body. The socket portion 20 comprises a hanging shaft 23. After the hook 211 is engaged with the hanging shaft 23, the body of the hook 211 is pivotally connected to the hanging shaft 23. A first end of the movable member comprises a first abutting portion 212, and the first abutting portion 212 abuts the first sliding portion 61. When the handheld assembly is inserted to the socket portion 20 to drive the movable member 21 to swing, a swinging movement of the movable member 21 drives the first abutting portion 212 to push the first sliding portion 61 to slide. When the handheld assembly is pulled out, the first elastic body 12 abuts the first sliding portion 61 to be reset, which then drives the movable member 21 to be reset. As required, a connection between the movable member 21 and the fixing portion 10 can also be adaptable to other connections, such as a sliding connection. The first elastic body 12 can also be disposed between the movable member 21 and the fixing portion 10. The first elastic body 12 drives the movable member 21 to be reset, and then the movable member 21 pulls the first switching mechanism 60 to slide to be reset (the first switching mechanism 60 is pulled to be connected to the movable member 21, for example, by a push block 11). If the socket portion 20 is pivotally connected the fixing portion 10 and a damper H is disposed between the socket portion 20 and the fixing portion 10, the socket portion 20 is connected to the fixing portion 10 by a clamp in some embodiments to prevent the socket portion 20 from being separated from the fixing portion 10 so as to enable the socket portion 20 to be pivotally connected to the fixing portion 10. Preferably, the socket portion 20 is configured to rotate in a preset angle, and the socket portion 20 can only rotate relative to the fixing portion 10 in the preset angle. The movable member 21 always corresponds to the push block 11 regardless of how the socket portion 20 rotates. For example, the push block 11 comprises a second abutting portion 111. The movable member 21 abuts the second abutting portion 111, and the movable member 21 always abuts the second abutting portion 111 regardless of how the movable member 21 rotates following the socket portion 20. The second abutting portion 111 comprises an arc portion, and a rotation axis of the arc portion and a rotation axis of the socket portion 20 are coaxial. A central angle of the arc portion is not less than the preset angle of the socket portion 20. A structure of the damper H is as follows. The socket portion 20 comprises a sleeve hole H11, and the sleeve hole H11 surrounds an outside of the fixing portion 10. An inner side of the sleeve hole H11 comprises a gear H1, and an elastic arc H2 is disposed on an outer side of the fixing portion 10. The elastic arc H2 is, for example, an O-ring. The elastic arc H2 and the gear H1 cooperate to achieve a damping function. The sleeve hole H11 comprises a lock member H12. The fixed base comprises a fastener H21. The lock member H12 and the fastener H21 cooperate to achieve a clamp connection. By structural design, a circumferential rotation can be realized between the lock member H12 and the fastener H21, but axial movement cannot be realized. That is, the above-mentioned clamp connection and the above-mentioned circumferential rotation are matched. The elastic arc H2 and the gear H1 are to improve stability. Interference by the O-ring and the gear can be reduced relative to an interference of a conventional cooperation of the O-ring and a plane, so as to facilitate assembly. An end of the first abutting portion 212 of the movable member 21 comprises at least one external hook portion 213. The at least one external hook portion 213 abuts an inner wall of the socket portion 20 to prevent the movable member 21 from being separated from the socket portion 20.
