[0023] Compared with the prior art, the beneficial effects of the present utility model at least include:

[0024] 1. By providing a connecting arm in the present utility model, the first end of the connecting arm is adjustably mounted on the base in terms of angle, the overhead shower head is adjustably mounted on the second end of the connecting arm away from the base in terms of angle, and the hand-held shower head is adjustably mounted on the base in terms of angle, so that the angle of the shower head can be adjusted. In particular, the adjustment range of the overhead shower head can be made larger, and it is convenient and flexible to use. The overhead shower head can also be translated with the water outlet angle unchanged (for example, with the water outlet direction always facing vertically downward) to change the water outlet position of the overhead shower head, improving the shower experience, and the structure is simple. In addition, the water flow channel connecting the base and the overhead shower head is directly arranged in the connecting arm. The connecting arm serves both as a connecting component between the base and the overhead shower head and as a water passing component. One component has two functions, and the structure is simpler, more compact, and ingeniously conceived.

[0025] 2. By providing a water flow switching switch to control the water outlet of the hand-held shower head or the overhead shower head, and by providing an angle adjustment switch to control the angle of the connecting arm and thus control the angle of the overhead shower head, it is convenient to use; and both the water flow switching switch and the angle adjustment switch are integrally arranged on the base, and the structure is more compact.

[0026] 3. Two connecting arms are provided and are respectively connected to the left and right sides of the base and the overhead shower head, and the connecting structure is more stable.

[0027] 4. The water flow switching switch is arranged on the outer side of the first connecting arm, and the angle adjustment switch is arranged on the outer side of the second connecting arm, which is more convenient to operate.

[0028] 5. The water flow switching switch is a switching knob, and the switching knob realizes water path switching through a switching shaft. And the switching shaft also serves as a first connecting part and is rotatably connected to the first end of the first connecting arm, and the structure is simple and ingenious.

[0029] 6. The angle adjustment switch is an adjusting nut. By tightening the first end of the second connecting arm against the base through the threaded connection between the adjusting nut and the connecting shaft, the angle of the connecting arm is restricted. By loosening the threaded connection between the adjusting nut and the connecting shaft, the first end of the second connecting arm is no longer pressed against the base, so that the angle of the connecting arm can be adjusted, thus realizing the adjustment and fixation of the angle of the connecting arm. The connecting shaft also serves as the second connecting part and is rotatably connected to the first end of the second connecting arm, with a simple and ingenious structure.

[0030] 7. The adjusting nut includes an inner sleeve and an outer sleeve that move axially relative to each other. The outer sleeve can move between an engaged position and a separated position relative to the inner sleeve. Such an adjusting nut with a clutch function has the effect of preventing misoperation, thus avoiding the risk of the overhead shower falling accidentally and hitting someone's head.

[0031] 8. When the overhead shower rotates gradually upward relative to the connecting arm, the cross-sectional area of the water flow channel between the water outlet end and the water inlet gradually decreases. On the one hand, the water flow rate can be adjusted by rotating the overhead shower, making the function more diverse; on the other hand, when the overhead shower is facing upward, problems such as water spraying upward onto the ceiling and the lamps on it can be avoided.

[0032] 9. The hand-held shower is installed on the base in an angle-adjustable manner through a universal ball head, and a clamping mechanism for clamping and releasing the universal ball head is provided on the hand-held shower, so that the hand-held shower can not only be angle-adjusted but also be disassembled and assembled, with a simple and reliable structure.

[0068] Please refer to Figures 1 to 21 , an adjustable combined shower head of a preferred embodiment of the present utility model includes a support arm 10, a base 20, a connecting arm 30, a hose 40, an overhead shower head 50, a hand-held shower head 60, etc.

[0069] The support arm 10 has a water inlet passage 11, and the water inlet end of the water inlet passage 11 is connected to a water supply pipe, and the water supply pipe is usually embedded in the wall.

[0070] The base 20 is fixedly connected to the water outlet end of the water inlet passage 11 of the support arm 10. A hollow cavity 21 is provided in the base 20. The cavity 21 has a water inlet 211, a first water outlet 212 and a second water outlet 213. The water inlet 211 is communicated with the water outlet end of the water inlet passage 11.

[0071] The first end 31 of the connecting arm 30 is angle-adjustably mounted on the base 20, and a water flow passage 33 is provided in the connecting arm 30.

[0072] The water inlet end of the hose 40 is communicated with the first water outlet 212.

[0073] The overhead shower head 50 is angle-adjustably mounted on the second end 32 of the connecting arm 30 away from the base 20, and the second water outlet 213 is communicated with the overhead shower head 50 through the water flow passage 33 of the connecting arm 30.

[0074] The hand-held shower head 60 is angle-adjustably mounted on the base 20 and connected to the water outlet end of the hose 40.

[0075] By providing the connecting arm 30, the first end 31 of the connecting arm 30 is adjustably mounted on the base 20 at an angle, the overhead shower 50 is adjustably mounted on the second end 32 of the connecting arm 30 away from the base 20 at an angle, and the handheld shower 60 is adjustably mounted on the base 20 at an angle. Thus, the angle of the shower can be adjusted. In particular, the adjustment range of the overhead shower 50 can be relatively large, and it is convenient and flexible to use. Since the overhead shower 50 is rotatably connected to the second end 32 of the connecting arm 30, and the second end 32 of the connecting arm 30 is also rotatably connected to the base 20, the overhead shower 50 can also be translated with the water outlet angle unchanged (for example, with the water outlet direction always facing vertically downward) to change the water outlet position of the overhead shower 50 (such as the front and rear positions), improving the shower experience, and the structure is simple. In addition, the water flow channel connecting the base 20 and the overhead shower 50 is directly provided in the connecting arm 30. The connecting arm 30 serves both as a connecting component between the base 20 and the overhead shower 50 and as a water passing component. One component has two functions, and the structure is simpler, more compact, and ingeniously conceived.

[0076] In this embodiment, the adjustable combined shower further includes a water flow switching switch 70 movably provided on the base 20. The water flow switching switch 70 controls the water inlet 211 to be selectively connected to the first water outlet 212 or the second water outlet 213, so as to control the water outlet of the handheld shower 60 or the overhead shower 50. The water inlet 211 can be only connected to the first water outlet 212 or the second water outlet 213, or can be simultaneously connected to the first water outlet 212 and the second water outlet 213. In this embodiment, the water flow switching switch 70 has 3 positions, namely the water stop position, the handheld shower water outlet position, and the overhead shower water outlet position. In the water stop position, the water inlet 211 is not connected to the first water outlet 212 and the second water outlet 213; in the handheld shower water outlet position, the water inlet 211 is connected to the first water outlet 212; in the overhead shower water outlet position, the water inlet 211 is connected to the second water outlet 213. Of course, in other embodiments, the water flow switching switch 70 can also have 4 positions. In addition to the above-mentioned water stop position, the handheld shower water outlet position, and the overhead shower water outlet position, a mixed water outlet position (i.e., both the handheld shower 60 and the overhead shower 50 discharge water) can also be provided. In the mixed water outlet position, the water inlet 211 is simultaneously connected to the first water outlet 212 and the second water outlet 213. Refer to Figures 11 - 13 , in order to enable the water flow switching switch 70 to have a sense of gear when switching, preferably a spring pin assembly 271 is provided on the switching shaft 27 described below. The spring pin assembly 271 can include a spring and a positioning pin, and a plurality of positioning grooves (not shown) are provided in the base 20. When the water flow switching switch 70 rotates, it drives the switching shaft 27 to rotate, and the switching shaft 27 further drives the positioning pin of the spring pin assembly 271 to cooperate with each positioning groove in turn, so as to obtain a sense of gear.

[0077] The adjustable combined shower head further includes an angle adjustment switch 80 movably disposed on the base 20. The angle adjustment switch 80 controls the angular position of the connecting arm 30 relative to the base 20, and the specific adjustment structure will be described in detail below.

[0078] In this embodiment, the connecting arm 30 includes a first connecting arm 30a and a second connecting arm 30b.

The second end 32 of the first connecting arm 30a is pivotally engaged with one side corresponding to the top spray shower head 50, and the second end 32 of the second connecting arm 30b is pivotally engaged with the other side corresponding to the top spray shower head 50. The water flow channel 33 is disposed in the first connecting arm 30a and / or the second connecting arm 30b. In this embodiment, it is selected to only provide the water flow channel 33 in the second connecting arm 30b. In other embodiments, the water flow channel 33 can also be provided in the first connecting arm 30a, or the water flow channel 33 is provided in both the first connecting arm 30a and the second connecting arm 30b. Two connecting arms 30 are provided and are respectively connected to the left and right sides of the top spray shower head 50, so that the support for the top spray shower head 50 is more reliable and the structure is more stable. The water flow channel 33 is directly provided in the connecting arm 30 to communicate the second water outlet 213 of the base 20 and the water inlet 511 of the top spray shower head 50, and the structure is more compact.

[0079] See Figures 19 - 21 , two pivot shafts 51 are provided on the top spray shower head 50, and are pivotally engaged with the second ends 32 of the two connecting arms 30 through the two pivot shafts 51. One of the pivot shafts 51 is through at both ends for water to pass through, and the water inlet 511 is disposed at the water inlet end of the pivot shaft 51.

[0080] In this embodiment, the water flow switching switch 70 and the angle adjustment switch 80 are respectively located on the left and right sides of the base 20, and the water flow switching switch 70 is located outside the first connecting arm 30a, and the angle adjustment switch 80 is located outside the second connecting arm 30b. The first end 31 of the first connecting arm 30a is located between the water flow switching switch 70 and the base 20, and the first end 31 of the second connecting arm 30b is located between the angle adjustment switch 80 and the base 20. With this arrangement, the overall layout is reasonable, the structure is compact, and the operation is convenient.

[0081] In this embodiment, a first opening 23 and a second opening 24 are symmetrically provided on the left and right sides of the base 20. The water flow switching switch 70 is located on one side of the first opening 23, and the angle adjustment switch 80 is located on one side of the second opening 24. With this arrangement, the overall layout is reasonable, the structure is compact, and the operation is convenient.

[0082] Specifically, the water flow switching switch 70 is a switching knob 70, and the first connecting portion is a switching shaft 27. The switching shaft 27 is disposed in the first opening 23 along the left-right direction of the base 20. The inner end of the switching shaft 27 cooperates with the first water outlet 212 and the second water outlet 213. The outer end of the switching shaft 27 extends out of the first opening 23 of the base 20 and is rotationally linked with the switching knob 70. The first end 31 of the first connecting arm 30a is sleeved outside the switching shaft 27 and rotates around the switching shaft 27. The first end 31 of the first connecting arm 30a is located between the side of the first opening 23 of the base 20 and the switching knob 70. The first connecting portion adopts the switching shaft 27, and the switching structure is simple.

[0083] See Figures 11 - 13 , a gasket 272 and an elastic member 273 are further provided on the switching shaft 27. Two ends of the elastic member 273 respectively abut between the gasket 272 and the switching shaft 27. The switching shaft 27 alternately blocks the first water outlet 212 and the second water outlet 213 through the gasket 272. When the gasket 272 blocks the first water outlet 212 (not shown), the water inlet 211 is communicated with the second water outlet 213. On the contrary, when the gasket 272 blocks the second water outlet 213 (see Figure 13 and Figure 14 ), the water inlet 211 is communicated with the first water outlet 212, thereby realizing the water path switching.

[0084] Specifically, the angle adjustment switch 80 is an adjustment nut 80, and the second connecting portion is a connecting shaft 28. The connecting shaft 28 is disposed in the second opening 24 along the left-right direction of the base 20. The inner end of the connecting shaft 28 is fixedly connected to the base 20 by a thread. The outer end of the connecting shaft 28 is threadedly connected to the adjustment nut 80. The first end 31 of the second connecting arm 30b is sleeved outside the connecting shaft 28 and rotates around the connecting shaft 28. The first end 31 of the second connecting arm 30b is located between the side of the second opening 24 of the base 20 and the adjustment nut 80. By the threaded connection between the adjustment nut 80 and the connecting shaft 28, the first end 31 of the second connecting arm 30b is pressed against the base 20 to limit the angle of the connecting arm 30; by loosening the threaded connection between the adjustment nut 80 and the connecting shaft 28, the first end 31 of the second connecting arm 30b is no longer pressed against the base, so that the angle of the connecting arm 30 can be adjusted, thereby realizing the adjustment and fixation of the angle of the connecting arm 30. The connecting shaft 28 also serves as the second connecting portion and is rotatably connected to the first end 31 of the second connecting arm 30b, and the structure is simple and ingenious.

[0085] In this embodiment, the adjusting nut 80 includes an inner nut 81 and an outer nut 82 which are sleeved inside and outside and can move axially relative to each other. The inner wall of the inner nut 81 is provided with an internal thread that matches the external thread provided on the connecting shaft 28. The outer wall of the inner nut 81 is provided with first engaging teeth 811, and the inner wall of the outer nut 82 is provided with second engaging teeth 821. The outer nut 82 can move relative to the inner nut 81 between an engaged position and a separated position. When in the engaged position, the first engaging teeth 811 and the second engaging teeth 821 are engaged. When in the separated position, the first engaging teeth 811 and the second engaging teeth 821 are separated. That is to say, the adjusting nut 80 adopts a clutch structure. When the outer nut 82 is axially driven to the engaged position so that the first engaging teeth 811 and the second engaging teeth 821 are engaged, the inner nut 81 can be driven to be screwed with the connecting shaft 28 by rotating the outer nut 82. On the contrary, when the outer nut 82 is axially driven to the separated position so that the first engaging teeth 811 and the second engaging teeth 821 are separated, the inner nut 81 cannot be driven to be screwed with the connecting shaft 28 by rotating the outer nut 82. Such a setting can prevent misoperation and avoid the situation that the top spray shower 50 quickly falls and hits people when the user rotates the adjusting nut 80 without knowing the function and operation method of the adjusting nut 80. Only after the outer nut 82 is axially driven so that the first engaging teeth 811 and the second engaging teeth 821 are engaged, can the loosening and tightening functions of the adjusting nut 80 be exerted. Otherwise, no matter how the outer nut 82 is rotated, the adjusting nut 80 cannot be loosened or tightened, that is, the function of the adjusting nut 80 cannot be exerted, and it is safer to use.

[0086] In this embodiment, a first anti-rotation tooth 34 is provided inside the first end 31 of the second connecting arm 30b, and a second anti-rotation tooth 281 that matches the first anti-rotation tooth 34 is provided on the connecting shaft 28. When the adjusting nut 80 is tightened, the first anti-rotation tooth 34 and the second anti-rotation tooth 281 are engaged. At this time, the angle of the connecting arm 30 cannot be adjusted; when the adjusting nut 80 is loosened, the first anti-rotation tooth 34 and the second anti-rotation tooth 281 are separated. At this time, the angle of the connecting arm 30 can be adjusted. It can be understood that the second anti-rotation tooth that matches the first anti-rotation tooth 34 can also be provided on the base 20. By providing the engaged first anti-rotation tooth 34 and second anti-rotation tooth 281, it can effectively avoid safety problems such as the connecting arm 30 changing its angle under the gravity of the top spray shower 50 and hitting people when there is no need to adjust the angle of the connecting arm 30. Of course, the setting of the first anti-rotation tooth 34 and the second anti-rotation tooth 281 is not necessary, and the connecting arm 30 can also achieve angle limitation through friction.

[0087] In this embodiment, a water passage is provided in the axial direction of the connecting shaft 28, a flow hole 282 communicating with the water passage is provided on the side wall of the connecting shaft 28, and the second water outlet 213 is connected to the water inlet end 331 of the water flow passage 33 provided in the second connecting arm 30b through the water passage and the flow hole 282. This arrangement makes the structure of the base 20 simple and compact.

[0088] See also Figure 20 and Figure 21 In this embodiment, the top spray shower head 50 is provided with a water inlet 511 connected to the water outlet end of the water flow channel 33 of the connecting arm 30. When the top spray shower head 50 is gradually rotated upward relative to the connecting arm 30, the flow cross-sectional area between the water outlet end 332 of the water flow channel 33 and the water inlet 511 gradually decreases. With this design, the water outlet flow rate of the top spray shower head 50 can also be adjusted by rotating the top spray shower head 50, and the functions are more diverse. In addition, when the top spray shower head 50 is gradually rotated upward relative to the connecting arm 30, the flow cross-sectional area between the water outlet end 332 of the water flow channel 33 and the water inlet 511 gradually decreases, that is, the water flow rate gradually decreases, which can prevent the water from spraying upward to the ceiling and wetting the ceiling and the lamps and the like thereon.

[0089] Specifically, in this embodiment, see Figure 20 and Figure 21 The cross-sectional shape of the water inlet 511 is designed to be a semicircle. Figure 8 , the flow cross-section shape of the water outlet end 332 of the water flow channel 33 is also designed to be a semicircle. After the water inlet 511 and the water outlet end 332 of the water flow channel 33 are connected, when the top spray shower 50 rotates to the point where the flow semicircle of the water inlet 511 coincides with the flow semicircle of the water outlet end 332, the water outlet flow of the top spray shower 50 is maximum; when the top spray shower 50 rotates to the point where the flow semicircle of the water inlet 511 partially coincides with the flow semicircle of the water outlet end 332, the water outlet flow of the top spray shower 50 becomes smaller; when the top spray shower 50 rotates to the point where the flow semicircle of the water inlet 511 is completely offset from the flow semicircle of the water outlet end 332, the water outlet flow of the top spray shower 50 is zero, that is, the top spray shower stops discharging water.

[0090] In this embodiment, the third opening 25 and the fourth opening 26 are respectively provided in the front and rear directions of the base 20, and the bottom wall of the base 20 is provided with a fifth opening 29. The third opening 25 is connected to the water inlet 211, and the fifth opening 29 is connected to the first water outlet 212. The third opening 25 is connected to the water outlet end of the water inlet channel 11 of the support arm 10, and a universal ball head 90 is provided at the fourth opening 26 of the base 20. With this design, the overall structure is more compact and simple.

[0091] To facilitate the removal and installation of the handheld shower head 60, a ball head mounting cavity 61 is provided on the handheld shower head 60, and the universal ball head 90 is detachably and rotatably installed in the ball head mounting cavity 61. A clamping mechanism capable of clamping and releasing the universal ball head 90 is provided on the handheld shower head 60. Through the clamping mechanism, it is convenient for the handheld shower head 60 to clamp and release the universal ball head 90 to realize the connection and separation of the handheld shower head 60 and the base 20, which is very convenient to use.

[0092] Specifically, for example, refer to Figure 5 , the clamping mechanism can be configured to include a button 62 and at least one clip 63. The clip 63 is used to enclose the ball head mounting cavity 61. The side wall of the clip 63 forms the side wall or part of the side wall of the ball head mounting cavity 61. The button 62 can drive the at least one clip 63 to move between the clamping position and the release position. When the button 62 is not pressed, the clip 63 is in the clamping position, thus tightly holding the universal ball head 90; when the button 62 is pressed, the clip 63 is in the release position, thus releasing the universal ball head 90, so that the handheld shower head 60 can be removed from the base 20. By setting the clamping mechanism, it is very convenient to remove and install the handheld shower head 60, with a simple structure and reliable function.

[0093] The usage method of the present utility model is as follows:

[0094] When it is necessary to make the overhead shower head 50 discharge water, rotate the water flow switching switch 70. The water flow switching switch 70 drives the switching shaft 27 to rotate, and the switching shaft 27 further drives the sealing gasket 272 provided thereon to move to the position of blocking the first water outlet 212, so that the water inlet 211 is communicated with the second water outlet 213. The water flows out from the second water outlet 213, and enters the water flow channel 33 of the second connecting arm 30b after passing through the water passing channel and the water passing holes 282 of the connecting shaft 28, and finally flows to the overhead shower head 50 to realize the water discharge of the overhead shower head 50;

[0095] When it is necessary to make the handheld shower head 60 discharge water, rotate the water flow switching switch 70. The water flow switching switch 70 drives the switching shaft 27 to rotate, and the switching shaft 27 further drives the sealing gasket 272 provided thereon to move to the position of blocking the second water outlet 213 (refer to Figure 13 and Figure 14 ), so that the water inlet 211 is communicated with the first water outlet 212. The water flows out from the first water outlet 212, and flows to the handheld shower head 60 through the hose 40 to realize the water discharge of the handheld shower head 60;

[0096] When it is necessary to adjust the water discharge angle or position of the overhead shower head 50, it can be achieved by directly rotating the overhead shower head 50 (as shown by the arrow F1 in Figure 4 ), or by rotating the connecting arm 30 (as shown by Figure 4as shown by the arrow F2). During the process of rotating the overhead shower 50 upward, the water flow rate of the overhead shower 50 gradually decreases, enabling flow rate adjustment. When rotating the connecting arm 30, it is necessary to first press the outer sleeve 82 inward so that the first engaging tooth 811 of the inner sleeve 81 and the second engaging tooth 821 of the outer sleeve 82 are engaged, and then loosen the angle adjustment switch 80 in the positive direction so that the first anti-rotation tooth 34 and the second anti-rotation tooth 281 are separated, thereby enabling the angle adjustment of the connecting arm 30; after adjusting the angle of the connecting arm 30 to the required angle, tighten the angle adjustment switch 80 in the reverse direction so that the first anti-rotation tooth 34 and the second anti-rotation tooth 281 are engaged again, thereby fixing the angle of the connecting arm 30. Finally, pull the outer sleeve 82 outward so that the first engaging tooth 811 of the inner sleeve 81 and the second engaging tooth 821 of the outer sleeve 82 are separated, restoring to the initial state. Preferably, a return spring (not shown) can also be provided between the outer sleeve 82 and the base 20 (such as the connecting shaft 28). In this way, after releasing the pressing on the outer sleeve 82, the outer sleeve 82 can be reset to the position separated from the inner sleeve 81 under the action of the return spring, which can prevent forgetting to reset the outer sleeve 82 to the initial position where the first engaging tooth 811 and the second engaging tooth 821 are separated.

[0097] When it is necessary to adjust the water outlet angle of the hand-held shower 60, the hand-held shower 60 can be directly rotated (such as Figure 4 as shown by the arrow F3). When it is necessary to remove the hand-held shower 60 from the base 20, just press the button 62 so that the clip 63 releases the universal ball head 90. When it is necessary to place the hand-held shower 60 on the base 20, just press the button 62 so that the clip 63 is in the released position. After inserting the universal ball head 90 into the ball head mounting cavity 61 of the hand-held shower 60, then release the button 62 so that the clip 63 returns to the clamping position to re-clamp the universal ball head 90, thereby realizing the rotatable connection between the hand-held shower 60 and the base 20.
