[0050] like Figures 1-14 As shown, an embodiment of the present application provides a shower 100 that can adapt to application scenarios of various installation heights.

[0051] like Figure 1 、 Figure 2 As shown, the shower 100 of the embodiment of the present application includes a shower rod 1, an overhead spray 2 disposed at the top of the shower rod 1, a mounting base 3 disposed at the bottom end of the shower rod 1, a shower head 4 disposed between the overhead spray 2 and the mounting base 3, and a handheld shower head 5 connected to the mounting base 3 and supported by the shower head 4. The overhead spray 2 and the handheld shower head 5 allow users to select different bathing styles. The mounting base 3 can be mounted with a water inlet device (not shown, such as a thermostatic valve or a switching valve) connected to the bottom end of the shower rod 1, and has a platform housing for users to place items.

[0052] like Figure 2-Figure 7 As shown, the shower rod 1 includes a vertical rod 11 and a horizontal rod 12. The horizontal rod 12 has a first end and a second end opposite to each other along its transverse direction. The first end is configured to mount the overhead shower 2, and the second end is slidably engaged with the vertical rod 11 to adjust the height of the horizontal rod 12, thereby adjusting the height of the overhead shower 2.

[0053] like Figure 4 As shown, the vertical rod 11 includes a vertical outer tube 110 and at least one vertical inner tube. In this embodiment, the at least one vertical inner tube includes a first vertical inner tube 111 and a second vertical inner tube 112 disposed within the vertical outer tube 110. In this embodiment, the tube body 110a of the vertical outer tube 110 is a fixed rod, while the crossbar 12 is a movable rod.

[0054] like Figure 6As shown, the crossbar 12 includes a transverse outer tube 120 and at least one transverse inner tube. The at least one transverse inner tube includes a first transverse inner tube 121 and a second transverse inner tube 122 arranged in the transverse outer tube 120. The first vertical inner tube 111 and the first transverse inner tube 121 are connected to form a first water supply channel for supplying water to the top shower 2; the second vertical inner tube 112 and the second transverse inner tube 122 are connected to form a second water supply channel for supplying water to the top shower 2. The water outlet panel of the top shower 2 is provided with a plurality of first water outlet holes (not shown) connected to the first water outlet channel, and a plurality of second water outlet holes (not shown) connected to the second water outlet channel.

[0055] like Figure 1 As shown, the mounting seat 3 in this embodiment is provided with an operating button 30 for controlling the on and off of the first water supply channel and the second water supply channel. The operating button 30 is connected to the water inlet device and controls the water inlet device. The operating device 30 in this embodiment is an operating button.

[0056] The shower rod 1 of the present embodiment utilizes a first vertical inner tube 111 and a second vertical inner tube 112, as well as a first transverse inner tube 121 and a second transverse inner tube 122, to provide two water channels for supplying water to the overhead shower 2, thereby enabling multiple water outlet modes for the overhead shower 2. The user can use an operating button 30 on the mounting base 3 at the water inlet end of the shower rod 1 to select whether the first and second water supply channels supply water together or separately, thereby resolving the difficulty in adjusting the water outlet mode of the overhead shower rod 1 in existing shower rods. Of course, the shower rod 1 can also implement multiple water supply channels by providing multiple inner tubes, which is not a limitation here.

[0057] like Figure 2 、 Figure 3 As shown, the vertical outer tube 110 includes a tube body 110a and a rear cover body 110b that can be detachably installed with the tube body 110a. The tube body 110a and the rear cover body 110b are assembled to form a receiving cavity (unnumbered), and the first vertical inner tube 111 and the second vertical inner tube 112 are arranged side by side in the receiving cavity.

[0058] like Figure 3 As shown, the first vertical inner tube 111 and the second vertical inner tube 112 each include a base tube 111a, 112a and an elevator tube 111b, 112b arranged in the height direction. The elevator tubes 111b, 112b are slidably and sealingly connected to the base tubes 111a, 112a and can maintain a seal with the base tubes 111a, 112a at any position within their lifting range.

[0059] The base pipes 111a, 112a and the lifting pipes 111b, 112b of this embodiment are all in the form of straight pipes, which are easy to slide and lift. The lifting pipes 111b, 112b of this embodiment are sleeved inside the base pipes 111a, 112a, and include sealing ends M that are sealed with the base pipes 111a, 112a. The sealing ends M are installed with one or more sealing rings (see Figure 5 ).

[0060] The lifting pipes 111b and 112b of the shower rod 1 of this embodiment can be raised and lowered based on the base pipes 111a and 112a, so that the water outlet point of the vertical rod can be adjusted to correspond to the water inlet end of the horizontal rod after the height is adjusted.

[0061] like Figure 2 、 Figure 6-Figure 9 As shown, the shower rod 1 also includes an adapter 13 connecting the vertical rod 11 and the horizontal rod 12. The adapter 13 and the horizontal rod 12 can be assembled separately or integrally. The adapter 13 has a socket 131 for the vertical rod 11 to pass through and can be moved vertically up and down relative to the vertical rod 11 through the socket 131. In this embodiment, the second end of the horizontal rod 12 is slidably connected to the vertical rod 11 via the adapter 13. The adapter 13 can be mounted on the vertical rod 11 and slide vertically up and down to adjust the height of the horizontal rod 12.

[0062] like Figure 7 As shown, a water flow channel 132 surrounding the socket 131 is provided inside the adapter 13, and the water flow channel 132 includes a first water inlet end 1321 and a second water inlet end 1322 respectively connected with the first vertical inner tube 111 and the second vertical inner tube 112 and for vertical water inlet, and a first water outlet end 1323 and a second water outlet end 1324 respectively connected with the first horizontal inner tube 121 and the second horizontal inner tube 122 and for horizontal water outlet.

[0063] The shower rod 1 of this embodiment is provided with an adapter 13, which can not only be assembled with the vertical rod 11 and slide vertically to adjust the height of the cross bar 12, but also a water flow channel 132 is provided inside the adapter 13 to transfer the water flow of the vertical rod 11 to the cross bar 12, thereby realizing the internal water channel connection between the cross bar 12 and the vertical rod 11. Moreover, it is possible to avoid providing a water supply hole connected to the transverse inner tube of the cross bar 12 on the front side of the vertical rod 11, thereby realizing the integrated appearance of the vertical outer tube 110, achieving a neat and beautiful effect.

[0064] The cross-sections of the vertical outer tube 110 and the horizontal outer tube 120 of this embodiment are both irregularly shaped, and are shown as square in the drawings. The irregularly shaped cross-sections described in the embodiments of the present application are non-circular cross-sections, and may be quadrilateral, pentagonal, or the like.

[0065] It should be noted that: Figure 13The solid line in the figure shows that the top spray 2 is at a first height, and the dotted line shows that the top spray 2 is lowered to a second height.

[0066] like Figure 2 、 Figure 10-13 As shown, the shower rod 1 of the embodiment of the present application further includes a locking device 14 equipped with the vertical rod 11 and the horizontal rod 12. The locking device 14 is used to control the horizontal rod 12 to switch between an active state and a fixed state.

[0067] like Figure 11 As shown, the locking device 14 includes a sliding base 140, a first friction block 141 and a second friction block 142 provided on the sliding base 140, and an operating rod assembly 143 equipped with the first friction block 141 and the second friction block 142. The sliding base 140 can slide with the vertical rod 11 of the shower rod 1 and is fixedly connected to the horizontal rod 12 of the shower rod 1. In this embodiment, the vertical rod 11 of the shower rod 1 is provided with a sliding groove 113 for the sliding base 140 to be installed and slide (see FIG. Figure 9 The vertical rod 11 also includes a removable top cover 114 for installing the locking device 14 (see Figure 8 ).

[0068] The first friction block 141 and the second friction block 142 are capable of opening and closing motions in the transverse direction of the sliding base 140. The first friction block 141 and the second friction block 142 have a first working state in which they move away from each other to respectively compress opposite sides of the vertical rod 11 of the shower rod 1, and a second working state in which they move toward each other to release the vertical rod 11 of the shower rod 1. The operating lever assembly 143 is used to control the switching between the first working state and the second working state of the first friction block 141 and the second friction block 142.

[0069] The opposing surfaces of the first friction block 141 and the second friction block 142 gradually move away from each other in an upward direction from the vertical bottom of the sliding base 140. The operating rod assembly 143 includes an extrusion device 1430 disposed between the opposing surfaces of the first friction block 141 and the second friction block 142, an operating rod 1431 for controlling the vertical movement of the extrusion device 1430, and a first elastic element 1432 for driving the extrusion device 1430 to reset. The operating rod 1431 passes through the gap between the first friction block 141 and the second friction block 142 and is connected to the extrusion device 1430. The extrusion device 1430 of this embodiment adopts an extrusion ball, but other shapes can also be used and are not limited here.

[0070] The operating rod 1431 of this embodiment is a push rod, which can drive the squeezing device 1430 to move upward, loosening the squeezing of the first friction block 141 and the second friction block 142, so that the first friction block 141 and the second friction block 142 are switched from the first working state of pressing the vertical rod 11 to the second working state of releasing the vertical rod 11.

[0071] In an exemplary embodiment, the opposing surfaces of the first friction block 141 and the second friction block 142 gradually move away from each other in a downward direction vertically above the sliding base 140. The operating rod 1431 is a pull rod that can drive the squeezing device 1430 downward, releasing the squeezing of the first friction block 141 and the second friction block 142, so that the first friction block 141 and the second friction block 142 switch from a first operating state of pressing the vertical rod 11 to a second operating state of releasing the vertical rod 11.

[0072] In an exemplary embodiment, one of the first friction block 141 and the second friction block 142 may be movable, and the other may be fixedly mounted on or integrally formed with the sliding base 140 .

[0073] like Figure 11 As shown, the sliding base 140 is further provided with pulley sets 144 on opposite sides along the transverse direction. The pulley sets 144 slide in cooperation with the side walls of the vertical rod 11 of the shower rod to reduce the sliding resistance of the sliding base 140 and facilitate user operation.

[0074] like Figure 12 As shown, the locking device 14 also includes a trigger assembly 145 for triggering the operation of the operating rod 1431. The trigger assembly 145 includes a base 1450 provided on the vertical rod 11, a button block 1451 that is assembled with the base 1450 and is movable, and a second elastic element (not shown) that drives the button block 1451 to reset. The button block 1451 cooperates with the operating rod 1431 to raise or lower the operating rod 1431. The base 1450 can be integrally formed with the vertical rod 11 or assembled in a separate manner. The button block 1451 of this embodiment is wedge-shaped and can move laterally when pressed by the user to trigger the action.

[0075] The first friction block 141 and the second friction block 142 of the embodiment of the present application are connected to the sliding base 140 via a third elastic element (not shown). The third elastic element provides a force for returning the first friction block 141 and the second friction block 142 to their original positions. The first elastic element, the second elastic element, and the third elastic element of the embodiment of the present application are all springs.

[0076] When the user needs to adjust the height of the overhead shower 2, the user can press the button block 1451 to drive the operating rod 1431 to rise, and the operating rod 1431 drives the squeezing device 1430 to rise. The first friction block 141 and the second friction block 142 lose their squeezing force and move closer to each other, releasing the squeezing on the side wall of the vertical rod 11, and the sliding base 140 can slide freely. In this state, the user can lift or lower the cross bar 12, and the cross bar 12 drives the sliding base 140 to follow the user's operation. When the predetermined position is reached, the user can release the button block 1451, and the squeezing device 1430 drives the squeezing device 1430 to reset under the action of the first elastic element 1432, and re-squeeze the first friction block 142 and the second friction block, so that the first friction block 142 and the second friction block are separated and pressed against the vertical rod 11, locking the cross bar 12.

[0077] The trigger assembly 145 implemented in this application has a simple structure, is easy to operate, and can be operated by the user at a lower position. In addition, the lifting tubes 111b and 112b of this embodiment adopt a two-stage design to facilitate the installation of the trigger assembly 145.

[0078] like Figure 1 、 Figure 14 As shown, the shower rod 1 also includes a constant force spring assembly 15 provided on the vertical rod 11 and suspending the horizontal rod 12. The constant force spring assembly 15 includes a roller body 150 installed on the top of the vertical rod 11, and a spring (not shown) connecting the roller body 150 and the horizontal rod 12. The constant force spring assembly 15 can prevent the horizontal rod 12 from falling, and can reduce part of the gravity of the horizontal rod 12. When the user raises the height of the horizontal rod 12, the user's operating force can be reduced. The constant force spring assembly 15 of this embodiment is installed on the top of the rear cover body 110b of the vertical rod 11. The rear cover body 110b of this embodiment includes an upper rear cover body 1101b and a lower rear cover body 1102b, and the constant force spring assembly 15 is provided on the upper rear cover body 1101b (see Figure 8 The upper rear cover 1101b is fixedly mounted on the wall, and the lower rear cover 1102b is slidably fitted to the tube body 110a and is fixedly connected to the adapter 13 and the trigger assembly 14 described below.

[0079] In this embodiment, the coil spring assembly 15 is fixedly connected to the sliding base 140 of the locking device 14. Because the sliding base 140 is fixedly connected to the adapter 13, which is in turn fixedly connected to the crossbar 12, the coil spring assembly 15 is suspended from the crossbar 12, resulting in a compact overall structure and easy installation. The constant-force coil spring assembly 15 and the locking device 14 are arranged vertically above each other and positioned above the locking device 14.

[0080] like Figure 3 、 Figure 13As shown, when the height of the shower rod 1 needs to be adjusted, the trigger assembly 145 can be raised or lowered manually or automatically. The trigger assembly 145 and the lower rear cover 1102b of the rear cover can slide relative to the tube body 110a of the vertical rod 11, and the trigger assembly 145 causes the lower rear cover 1102b to be raised or lowered. Since the lower rear cover 1102b is fixedly mounted to the adapter 13, the lower rear cover 1102b drives the adapter 13 to be raised or lowered, and thus drives the cross bar 12 to be raised or lowered.
