[0030] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0031] Embodiment 1

[0032] Reference Figures 1 to 3 As shown, the first embodiment provides a shower switching device with a liftable elbow (hereinafter referred to as a shower switching device), which is used for switching the water path of a shower system. The shower switching device includes: Figure 8 The valve seat 1 shown in the figure has a water inlet channel 11 and two water outlet channels, and also includes a switching shaft assembly 2 for switching the water path and a bend pipe 3 for showering. The valve seat 1 has Fig. 9 The installation channel 14 shown accommodates the switching shaft assembly 2, and the water inlets of the two water outlet channels are connected to the water inlet channel 11 through the installation channel 14 to form two water paths. The switching shaft assembly 2 includes two sealing parts that cooperate with the water inlet sealing of the water outlet channels. The switching shaft assembly 2 can be rotatably assembled in the installation channel 14 of the valve seat 1, and the sealing part of the switching shaft assembly 2 is sealed at the water inlet of the corresponding water outlet channel to block the corresponding water path. The sealing part of the switching shaft assembly 2 is rotated away from the water inlet of the water outlet channel to open the corresponding water path. The elbow 3 can be assembled on the valve seat 1 in a liftable manner.

[0033] In this embodiment, the water inlet end of the water inlet channel 11 is connected to an external water source, and the installation channel 14 of the valve seat 1 is respectively provided with a first opening, a second opening and a third opening, the first opening is connected to the water outlet end of the water inlet channel 11, the second opening and the third opening are respectively connected to two water outlet channels, and the two water outlet channels are respectively connected to a handheld shower and a top spray shower, and the second opening and the third opening are the water inlets corresponding to the two water outlet channels.

[0034] The switch shaft assembly 2 is rotatably assembled in the installation channel 14 of the valve seat 1 to drive the sealing portion of the switch shaft assembly 2 to rotate synchronously in the installation channel 14 of the valve seat 1 .

[0035] By rotating the switching shaft assembly 2, the sealing part of the switching shaft assembly 2 is driven to seal at the water inlet of the corresponding water outlet channel to seal the corresponding water path, and to move away from the water inlet of the corresponding water outlet channel to open the corresponding water path, thereby realizing the switching of multiple water paths. Moreover, by replacing the existing valve core with the switching shaft assembly 2, the structure of the shower switching device is simple and the cost is low, and the height of the curved pipe 3 can be adjusted to meet various user needs.

[0036] In another preferred embodiment, Figure 7As shown, the switching shaft assembly 2 includes a rotating shaft 21 and two first sealing members 22 mounted on the outer peripheral surface of the rotating shaft 21. The outer wall of the valve seat 1 is provided with an installation opening 142 connected to the installation channel 14. The rotating shaft 21 passes through the installation opening 142 and is rotatably mounted on the installation channel 14. The first sealing member 22 is the sealing portion. In this way, the switching shaft assembly 2 has a simple structure and is durable.

[0037] More specifically, the water inlets of the two water outlet channels are arranged along the extension direction of the installation channel 14 and are located on the same straight line, and the axial direction of the rotating shaft 21 is parallel to the arrangement direction of the water inlets of the water outlet channels.

[0038] The first sealing member 22 is a sealing gasket, and the difference between the two first sealing members 22 on the circumferential projection of the rotating shaft 21 is 90 degrees.

[0039] A second sealing member 23 is provided on the outer circumferential surface of one end of the rotating shaft 21 close to the mounting opening 142. The second sealing member 23 abuts against the inner circumferential wall of the mounting channel 14 to form a sealing fit. Specifically, the second sealing member 23 is a sealing ring, which is sleeved on the outer circumferential surface of the rotating shaft 21 and is sealed with the inner circumferential wall of the mounting channel 14 to prevent water from leaking from the mounting opening 142.

[0040] The outer circumferential surface of one end of the rotating shaft 21 close to the installation opening 142 is provided with an outwardly protruding limiting protrusion 24, and the inner circumferential wall of the installation channel 14 has an inwardly concave limiting groove 141. The circumferential rotation of the limiting protrusion 24 is limited by the two ends of the limiting groove 141, so that one of the first sealing members 22 can switch between the position of blocking and being away from the water inlet of the corresponding water outlet channel.

[0041] In this specific embodiment, Figure 4 and Figure 5 As shown, the limiting groove 141 is a fan-shaped groove, and the two ends of the fan-shaped groove are divided into a first end and a second end. The two sealing gaskets are respectively a first sealing gasket and a second sealing gasket, the first end corresponds to the first sealing gasket, and the second end corresponds to the second sealing gasket.

[0042] The two outlet channels are divided into Figure 2 The first water outlet channel 12 and the second water outlet channel 13 are shown as being arranged on the left and right. The first water outlet channel 12 is used to connect to a handheld shower head, and the second water outlet channel 13 is used to connect to an overhead shower head. The second opening is connected to the first water outlet channel 12, and the third opening is connected to the second water outlet channel 13.

[0043] When the rotating shaft 21 is rotated to make the limiting protrusion 24 abut against the first end, the first sealing gasket is driven by the rotating shaft 21 and rotated to the second opening, so that the second opening is completely covered and sealed, so that the first sealing gasket blocks the second opening, and then blocks the second water outlet channel 13. At the same time, the second sealing gasket is driven by the rotating shaft 21 and moves away from the third opening, so that the third opening is completely opened, thereby realizing the connection between the second water outlet channel 13 and the water inlet channel 11. At this time, the shower switching device can only realize the opening of the overhead shower.

[0044] When the rotating shaft 21 is rotated to make the limiting protrusion 24 abut against the second end, the first sealing gasket is driven by the rotating shaft 21 and moves away from the second opening, so that the second opening is fully opened, thereby realizing the connection between the first water outlet channel 12 and the water inlet channel 11. At the same time, the second sealing gasket is driven by the rotating shaft 21 and rotates to the third opening, so that the third opening is fully covered and sealed, so that the second sealing gasket blocks the third opening, thereby blocking the second water outlet channel 13. At this time, the shower switching device can only realize the opening of the handheld shower.

[0045] When the rotating shaft 21 is rotated so that the limiting protrusion 24 is located between the first end and the second end, the first sealing gasket does not completely cover the second opening, and the second sealing gasket does not completely cover the third opening, that is, the second opening and the third opening are both in an incompletely blocked state. At this time, the shower switching device can simultaneously open the overhead shower and the hand-held shower.

[0046] Of course, in other embodiments, the phase difference between the two first sealing members 22 on the circumferential projection of the rotating shaft 21 may also be 0 to 90 degrees.

[0047] In addition, the number of the water outlet channels and the first sealing member 22 is not limited thereto, and the number of the water outlet channels and the first sealing member 22 may also be 3 or 4, which will not be described in detail herein.

[0048] In another preferred embodiment, Figure 7 and Fig.10 As shown, the switching shaft assembly 2 further includes a rotating handle 25, which is fixed to one end of the rotating shaft 21 outside the valve seat 1. By turning the rotating handle 25, the user can switch the water path with one hand.

[0049] In another preferred embodiment, Figure 6 As shown, the shower switching device also includes an elastic locking assembly 4, the valve seat 1 has a mounting through hole 15 that passes through the upper and lower surfaces, the elbow 3 can be movably passed through the mounting through hole 15, and the elastic locking assembly 4 can be detachably assembled between the elbow 3 and the inner wall of the mounting through hole 15 to hold the elbow 3 tightly.

[0050] More specifically, the elastic locking assembly 4 includes a threaded sleeve 41 and an elastic expansion body 42 assembled on the inner wall of the threaded sleeve 41. The outer circumferential surface of the threaded sleeve 41 and the inner circumferential wall of the mounting hole 15 are both provided with threads. The threaded sleeve 41 and the elastic expansion body 42 are both inserted into the gap between the outer circumferential surface of the bent pipe 3 and the inner circumferential wall of the mounting hole 15. The threaded sleeve 41 and the valve seat 1 are connected by threads to apply a pre-tightening force to the elastic expansion body 42, thereby clamping the bent pipe 3.

[0051] When the height of the elbow 3 needs to be adjusted, the threaded sleeve 41 is first rotated to release the threaded connection between the threaded sleeve 41 and the valve seat 1, so that the pre-tightening force on the elastic expansion body 42 disappears and the deformation is restored. At this time, the elbow 3 located in the elastic locking assembly 4 can move up and down to adjust the corresponding height.

[0052] After the height of the elbow 3 is determined, the threaded sleeve 41 is screwed into the valve seat 1 again to form a threaded connection between the threaded sleeve 41 and the valve seat 1, thereby applying a certain pre-tightening force to the elastic expansion body 42 to hold the elbow 3 tightly to fix the elbow 3.

[0053] In another preferred embodiment, Fig.10 As shown, the shower switching device further comprises a shower head support 5 for fixing a hand-held shower head, and the shower head support 5 is rotatably mounted on one side of the valve seat 1 .

[0054] In specific implementation, the handheld shower is connected to the water outlet of the first water outlet channel 12 through a hose, the overhead shower is fixedly assembled on the top water outlet of the curved pipe 3, and the bottom water inlet of the curved pipe 3 is connected to the water outlet of the second water outlet channel 13 through a hose.

[0055] When there is no need to hold the handheld shower head by hand, the handheld shower head is placed on the shower head support 5, and the shower head support 5 is rotated to adjust the water spraying angle of the handheld shower head to meet the showering needs of different users.
