[0050] As shown in Figures 1-14 , the present application provides a shower 100 which can adapt to various installation height application scenarios.

[0051] As shown in Figure 1 , Figure 2 , the shower 100 of the present application comprises a shower rod 1, a top spray 2 arranged at the top of the shower rod 1, a mounting seat 3 arranged at the bottom end of the shower rod 1, a shower head seat 4 arranged between the top spray 2 and the mounting seat 3, and a handheld shower 5 connected with the mounting seat 3 and supported on the shower head seat 4. Among them, the top spray 2 and the handheld shower 5 can provide users with different bathing modes, the mounting seat 3 can be installed with a water inlet device (not shown, such as a temperature regulating valve, a switching valve) connected with the bottom end of the shower rod 1, etc., and has a platform shell, which can be used by users to place articles.

[0052] As shown in Figures 2-7 , the shower rod 1 comprises a vertical rod 11 and a horizontal rod 12. The horizontal rod 12 has opposite first and second ends along its horizontal direction, the first end is arranged to install the top spray 2, and the second end is slidably fitted with the vertical rod 11 to adjust the height of the horizontal rod 12, thereby adjusting the height of the top spray 2.

[0053] As shown in Figure 4 , the vertical rod 11 comprises a vertical outer tube 110 and at least one vertical inner tube. In the present embodiment, the at least one vertical inner tube comprises a first vertical inner tube 111 and a second vertical inner tube 112 arranged in the vertical outer tube 110. The tube body 110a of the vertical outer tube 110 in the present embodiment is an inactive fixed rod, and the horizontal rod 12 is a movable active rod.

[0054] As shown in 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 disposed within 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 the top spray 2; the second vertical inner tube 112 and the second transverse inner tube 122 are connected to form a second water supply channel for the top spray 2. The water outlet panel of the top spray 2 is provided with a plurality of first water outlet holes (not shown) communicating with the first water outlet channel, and a plurality of second water outlet holes (not shown) communicating with the second water outlet channel.

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

[0056] The shower rod 1 in this embodiment employs a first vertical inner pipe 111 and a second vertical inner pipe 112, and a first horizontal inner pipe 121 and a second horizontal inner pipe 122, to supply water to the top spray 2 via two water channels, thereby enabling multiple water outlet modes for the top spray 2. Users can select whether the first and second water supply channels supply water together or separately via the operation button 30 on the mounting base 3 at the water inlet end of the shower rod 1, thus solving the problem of difficulty in adjusting the top spray water outlet mode in existing shower rods 1. Of course, the shower rod 1 can also achieve multiple water supply channels by setting multiple inner pipes; this is not limited here.

[0057] like Figure 2 , Figure 3 As shown, the vertical outer tube 110 includes a tube body 110a and a rear cover 110b that can be detachably installed with the tube body 110a. The tube body 110a and the rear cover 110b are fitted together to form a receiving cavity (not labeled). 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, both the first vertical inner tube 111 and the second vertical inner tube 112 include base tubes 111a and 112a and rising tubes 111b and 112b mounted along the height direction. The rising tubes 111b and 112b are slidably and sealingly connected to the base tubes 111a and 112a and can maintain a seal with the base tubes 111a and 112a at any position within their lifting range.

[0059] The base pipes 111a and 112a and the lifting pipes 111b and 112b of the shower rod 1 of the embodiment are in the form of straight pipes, which are convenient for sliding lifting. The lifting pipes 111b and 112b of the embodiment are sleeved in the base pipes 111a and 112a and include sealing end portions M that are sealingly sleeved with the base pipes 111a and 112a, and one or more sealing rings (see Figure 5 ) are installed on the sealing end portions M.

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

[0061] As shown in Figure 2 , Figures 6-9 , the shower rod 1 further includes an adapter 13 that connects the vertical rod 11 and the horizontal rod 12, and the adapter 13 can be assembled in a split body or integrally formed. The adapter 13 is provided with a sleeving port 131 through which the vertical rod 11 passes and can move up and down along the vertical direction relative to the vertical rod 11. The second end of the horizontal rod 12 of the embodiment is connected to the vertical rod 11 through the sliding assembly of the adapter 13, and the adapter 13 can be installed on the vertical rod 11 and slid up and down along the vertical direction to adjust the height of the horizontal rod 12.

[0062] As shown in Figure 7 , the adapter 13 is internally provided with a water flow channel 132 that surrounds the sleeving port 131, and the water flow channel 132 includes a first water inlet end 1321 and a second water inlet end 1322 that respectively communicate with the first vertical inner pipe 111 and the second vertical inner pipe 112 and are used for vertical water inlet, and a first water outlet end 1323 and a second water outlet end 1324 that respectively communicate with the first horizontal inner pipe 121 and the second horizontal inner pipe 122 and are used for horizontal water outlet.

[0063] The shower rod 1 of the embodiment is provided with the adapter 13, which can not only be assembled with the vertical rod 11 to slide along the vertical direction to adjust the height of the horizontal rod 12, but also internally provided with the water flow channel 132 to connect the internal waterways of the horizontal rod 12 and the vertical rod 11, and can avoid the water supply hole for connecting the horizontal inner pipe of the horizontal rod 12 on the front surface of the vertical rod 11, realize the appearance integration of the vertical outer pipe 110, and achieve the effect of neatness and beauty.

[0064] The vertical outer pipe 110 and the horizontal outer pipe 120 of the embodiment are both in the form of special-shaped cross sections, which are square in the drawings. The special-shaped cross section of the embodiment is a non-circular cross section, which can be in the form of quadrilateral or pentagon.

[0065] It should be noted that: Figure 13The solid line in the figure depicts the top spray 2 at the first height, and the dashed line depicts the lowering of the top spray 2 to the second height.

[0066] As shown in Figure 2 , Figures 10-13 , the shower rod 1 further comprises a locking device 14 matched with the vertical rod 11 and the horizontal rod 12. The locking device 14 is used to control the switching of the horizontal rod 12 between the active state and the fixed state.

[0067] As shown in Figure 11 , the locking device 14 comprises a sliding base 140, a first friction block 141 and a second friction block 142 arranged on the sliding base 140, and an operating rod assembly 143 matched with the first friction block 141 and the second friction block 142. The sliding base 140 is capable of sliding with the vertical rod 11 of the shower rod 1 and is fixedly connected with the horizontal rod 12 of the shower rod 1. In the embodiment, the vertical rod 11 of the shower rod 1 is provided with a sliding groove 113 (see Figure 9 ) for mounting and sliding of the sliding base 140. Figure 8

[0068] The first friction block 141 and the second friction block 142 are capable of opening and closing movement in the transverse direction of the sliding base 140. The first friction block 141 and the second friction block 142 comprise a first working state of moving away from each other to press the opposite sides of the vertical rod 11 of the shower rod 1 and a second working state of closing to each other to release the vertical rod 11 of the shower rod 1. The operating rod assembly 143 is used to control the switching of the first friction block 141 and the second friction block 142 between the first working state and the second working state.

[0069] The opposite surfaces of the first friction block 141 and the second friction block 142 gradually move away from each other in the upward direction below the vertical direction of the sliding base 140. The operating rod assembly 143 comprises a pressing device 1430 arranged between the opposite surfaces of the first friction block 141 and the second friction block 142, an operating rod 1431 for controlling the vertical movement of the pressing device 1430, and a first elastic element 1432 for returning the pressing device 1430. The operating rod 1431 is connected with the pressing device 1430 through the gap between the first friction block 141 and the second friction block 142. The pressing device 1430 of the embodiment adopts a pressing ball, and of course other shapes can also be adopted, which are not limited herein.

[0070] The operating rod 1431 of the embodiment is a push rod, which can drive the pressing device 1430 to move upward, release the pressing of the first friction block 141 and the second friction block 142, and switch the first friction block 141 and the second friction block 142 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 opposite surfaces of the first friction block 141 and the second friction block 142 gradually move away from each other in a downward direction above the vertical direction of the sliding base 140. The operating rod 1431 is a pull rod, which can drive the pressing device 1430 to move downward, thereby releasing the pressing 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.

[0072] In an exemplary embodiment, the first friction block 141 and the second friction block 142 are one movable and the other is fixedly installed or integrally formed with the sliding base 140.

[0073] As shown in Figure 11 The sliding base 140 is further provided with a pulley set 144 on the opposite sides in the transverse direction, which cooperates with the side wall of the vertical rod 11 of the shower rod to reduce the sliding resistance of the sliding base 140, thereby facilitating the operation of the user.

[0074] As shown in Figure 12 The locking device 14 further includes a trigger assembly 145 for triggering the operation of the operating rod 1431. The trigger assembly 145 includes a seat body 1450 provided on the vertical rod 11, a button block 1451 fitted with the seat body 1450 and movable, and a second elastic element (not shown) for driving the button block 1451 to reset. The button block 1451 cooperates with the operating rod 1431 to lift or lower the operating rod 1431. The seat body 1450 can be integrally formed with the vertical rod 11 or separately assembled. The button block 1451 of the present embodiment is wedge-shaped, which can be moved in the transverse direction under the pressing of the user to trigger the operation.

[0075] The first friction block 141 and the second friction block 142 of the present embodiment are connected with the sliding base 140 through a third elastic element (not shown), which provides a restoring force for the first friction block 141 and the second friction block 142. The first elastic element, the second elastic element and the third elastic element of the present embodiment all adopt springs.

[0076] When the user needs to adjust the height of the top spray 2, the user can press the button block 1451 to drive the operating rod 1431 to rise, and the operating rod 1431 drives the pressing device 1430 to rise, and the first friction block 141 and the second friction block 142 lose the pressing force and approach each other, releasing the pressing on the side wall of the vertical rod 11, and the sliding base 140 can be freely slid. In this state, the user can lift or lower the cross rod 12, and the cross rod 12 drives the sliding base 140 to follow the user's operation. When reaching the predetermined position, the user can release the button block 1451, and the pressing device 1430 drives the pressing device 1430 to reset under the action of the first elastic element 1432, and re-presses the first friction block 142 and the second friction block, so that the first friction block 142 and the second friction block separate and press the vertical rod 11, locking the cross rod 12.

[0077] The trigger assembly 145 of the embodiment has simple structure, convenient operation, and can facilitate the user to operate at a lower position. In addition, the lifting pipes 111b and 112b of the embodiment are designed in two sections, which can facilitate the installation of the trigger assembly 145.

[0078] As shown in Figure 1 , Figure 14 , the shower rod 1 further comprises a constant force spring assembly 15 arranged on the vertical rod 11 and suspended with the cross rod 12. The constant force spring assembly 15 comprises a roller body 150 arranged on the top end of the vertical rod 11, and a coil spring (not shown) connecting the roller body 150 and the cross rod 12. The constant force spring assembly 15 can prevent the cross rod 12 from falling, and can reduce the gravity of part of the cross rod 12. When the user lifts the height of the cross rod 12, the operation force of the user can be reduced. The constant force spring assembly 15 of the embodiment is arranged on the top of the rear cover body 110b of the vertical rod 11. The rear cover body 110b of the embodiment comprises an upper rear cover body 1101b and a lower rear cover body 1102b, and the constant force spring assembly 15 is arranged on the upper rear cover body 1101b (see Figure 8 ). The upper rear cover body 1101b is fixedly arranged on the wall, and the lower rear cover body 1102b is slidably arranged with the pipe body 110a, and is fixedly connected with the adapter 13 and the trigger assembly 14 described below.

[0079] The coil spring assembly 15 in the embodiment is fixedly connected with the sliding base 140 of the locking device 14. Since the sliding base 140 is fixedly connected with the adapter 13, and the adapter 13 is fixedly connected with the cross rod 12, the coil spring assembly 15 is suspended with the cross rod 12, and the overall structure is compact and easy to install. The constant force spring assembly 15 and the locking device 14 are arranged vertically and above the locking device 14.

[0080] As shown in Figure 3 , Figure 13When the height of the shower rod 1 needs to be adjusted, the trigger assembly 145 and the lower rear cover body 1102b can slide relative to the pipe body 110a of the vertical rod 11 by lifting or lowering the trigger assembly 145 manually or automatically, and the trigger assembly 145 lifts or lowers the lower rear cover body 1102b. Since the lower rear cover body 1102b is fixedly installed with the adapter 13, the lower rear cover body 1102b lifts or lowers the adapter 13, and then lifts or lowers the horizontal rod 12.
