Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] like Figures 1 to 10 As shown, a shower arm assembly according to this embodiment includes: —A support arm body 10 having an adjustment groove 30 extending in a first direction; —A slider-type adjustment seat 20 disposed in the adjustment groove 30 and capable of reciprocating along the first direction; —At least one rack 31 is disposed on the inner wall of the adjusting groove 30, and the at least one rack 31 is a fixing member; —The meshing structure 21 disposed on the adjusting seat 20 engages with the rack 31 in the locked state to position the adjusting seat 20. In the unlocked state, the meshing structure 21 moves away from the rack 31 to disengage, thereby allowing the adjusting seat 20 to move along the first direction.

[0022] Therefore, the adjusting seat 20 can be used to place and install water outlet devices such as the shower head 40, and can slide along the first direction in the adjusting groove 30 to adjust the position of the shower head 40. In this embodiment, the first direction can be the vertical direction, but it is not limited to this. Thus, after the adjusting seat 20 slides up and down, the position of the shower head 40 can be fixed and limited by engaging the meshing structure 21 with the rack 31 in the adjusting groove 30. This ensures that the height of the shower head 40 is adjustable while ensuring the reliable and stable position of the shower head 40, making it less likely to slide down and shift, thus improving reliability.

[0023] like Figure 4 and Figure 5 In this embodiment, the meshing structure 21 includes a first mating member 211 and a second mating member 212 arranged opposite to each other, and two opposing racks 31 are provided in the adjusting groove 30, with the racks 31 extending vertically upwards and downwards.

[0024] In the locked state, the first mating member 211 and the second mating member 212 are respectively engaged with the two racks 31; in the unlocked state, the first mating member 211 and the second mating member 212 are respectively disengaged from the racks 31 and simultaneously disengage from the above-mentioned at least two engagements.

[0025] By setting two mutually cooperating first mating components 211 and second mating components 212, the positioning and fixing effect of the adjusting seat 20 and the adjusting groove 30 can be improved.

[0026] Specifically, the engagement structure 21 also includes a sliding seat 213, an unlocking button 214, and a locking spring 215.

[0027] The sliding seat 213 has a sliding block 2131 inserted into and sliding in the adjusting groove 30, and the sliding block 2131 is located between the two racks 31 (e.g., Figure 4 This facilitates the sliding of the sliding seat 213 along the adjusting groove 30.

[0028] The first mating component 211 and the second mating component 212 are respectively installed at intervals on both sides of the sliding block 2131 near the rack 31, and can reciprocate along the second direction between the sliding block 2131 and the rack 31. The second direction is perpendicular to the first direction. In this embodiment, the second direction is described as the left and right direction, but it is not limited thereto.

[0029] The first mating member 211 and the second mating member 212 are respectively provided with limiting teeth 216 that are movably engaged with the rack 31 on opposite sides; the locking spring 215 is provided on the side adjacent to the first mating member 211 and the second mating member 212. The locking spring 215 provides elastic force to separate the first mating member 211 and the second mating member 212 from each other, so that the limiting teeth 216 of the first mating member 211 and the second mating member 212 can be pressed and engaged on the rack 31 in the static state, thereby realizing the positioning and fixing of the adjusting seat 20.

[0030] The unlock button 214 is mounted on the surface of the sliding seat 213 and has a driving part 217 that is connected to the first mating member 211 and the second mating member 212. When the unlock button 214 is pressed, the driving part 217 drives the first mating member 211 and the second mating member 212 to move closer to each other. Thus, the unlock button 214 can be manually pressed to release the engagement between the limiting tooth 216 and the rack 31, so that the adjusting seat 20 can move up and down along the first direction.

[0031] In this embodiment, there are two unlocking buttons 214 arranged symmetrically, positioned at opposite ends in a first direction between the first mating member 211 and the second mating member 212, i.e., at the top and bottom. These buttons are used to synchronously move the first mating member 211 and the second mating member 212 closer together. Therefore, during adjustment, simply pressing and pinching the two unlocking buttons up and down easily and effortlessly moves the first mating member 211 and the second mating member 212 closer together, overcoming the elasticity of the locking spring 215, causing the limiting teeth 216 and the rack 31 to separate, thus unlocking the device.

[0032] In this embodiment, the sliding seat 213 may have a movable cavity 2132. The sliding block 2131 is provided with side openings 2133 communicating with the movable cavity 2132 on both sides (left and right sides in this embodiment) along the second direction. The sliding seat 213 away from the sliding block 2131 is provided with unlocking openings 2134 communicating with the movable cavity 2132 on both sides (upper and lower sides in this embodiment) along the first direction.

[0033] The first mating component 211 and the second mating component 212 are both installed in the movable cavity 2132 and their respective limiting teeth 216 protrude from the two side openings 2133; the first mating component 211 and the second mating component 212 each have a component body 218 that is limited to the movable cavity 2132, the locking spring 215 is provided between the two component bodies 218, and the component bodies 218 are respectively provided with guide slopes 2181 at both ends along the first direction.

[0034] Both unlocking buttons 214 are installed in the movable cavity 2132 and each includes a button 2141 extending from the surface of the sliding seat 213 through the unlocking opening 2134 and a driving part 217 located in the movable cavity 2132. The driving part 217 has a notch 2171 on the side near the first mating member 211 and the second mating member 212. The left and right sides of the notch 2171 have driving inclined surfaces 2172 that mate with the guide inclined surface 2181, respectively.

[0035] Therefore, when the button 2141 protruding above and below the sliding seat 213 of the adjustment part is pressed, the upper and lower driving parts 217 move closer together along the first direction, and the four driving slopes 2172 and four guide slopes 2181 of the upper and lower notches 2171 cooperate to drive the first cooperating component 211 and the second cooperating component 212 on both sides of the second direction to move closer together.

[0036] like Figure 2 , Figure 4 and Figure 5 As shown, the opening side of the adjustment groove 30 forms a limiting guide edge 32, which slides with the limiting groove 22 provided on the adjustment seat 20 to limit the adjustment seat 20 from dislodging outward from the direction of the adjustment groove 30. This can improve the convenience and reliability of the adjustment of the adjustment seat 20 and make it more convenient to use.

[0037] Specifically, the limiting teeth 216 of the first mating member 211 and the second mating member 212 respectively form the limiting groove 22 between the left and right protrusions 2135 on the front side of the sliding seat 213 away from the sliding block 2131, and a friction pad 2136 can also be installed on the rear side of the protrusion 2135.

[0038] like Figure 2 As shown, in this embodiment, the adjusting seat 20 is provided with a shower head connection part 23 on the side away from the meshing structure 21. The shower head connection part 23 includes a fixed seat 231, a movable head 232 and a magnetic suction assembly 233.

[0039] One side of the fixed base 231 is detachably connected to the side of the meshing structure 21 away from the adjusting groove 30, and the two can be connected by threads; the other side of the fixed base 231 has a movable hole 2311; one side of the movable head 232 is provided with a ball head 2321, which is rotatably assembled in the movable hole 2311; the other side of the movable head 232 is equipped with the magnetic suction assembly 233, which is used to movably attract and fix the shower head 40.

[0040] Therefore, the shower head connection part 23 can flexibly attach and fix the shower head 40 through the magnetic suction component 233, and the ball head 2321 and the movable hole 2311 are designed to cooperate to easily adjust the angle of the shower head 40 to provide a variety of water outlet angles.

[0041] Of course, the shower head connection part 23 can adopt common structures such as a "C"-shaped shower head holder (not shown in the figure), and is not limited to this embodiment. The mating structure of the magnetic suction component 233 and the shower head 40 can refer to the prior art.

[0042] like Figure 1 , Figure 2 and Figure 6As shown, the support arm body 10 may include a first support arm 11 and a second support arm 12; one end of the first support arm 11 and one end of the second support arm 12 are hinged to each other; the two can be unfolded or bent and folded to reduce the overall size of the shower support arm assembly and facilitate packaging and transportation.

[0043] The first support arm 11 has a top spray connection port 111 at the other end away from the second support arm 12; the top spray connection port 111 can be a threaded interface, which can be used to screw and fix the top spray 50, and facilitate the extension of the support for the top spray 50. The second support arm 12 is provided with the adjustment groove 30, and the adjustment groove 30 is provided with a slider-type adjustment seat 20, which can be used to fix the shower head 40.

[0044] In this embodiment, the width of the top spray connection port 111 of the first support arm 11 may not be greater than the width of the adjustment groove 30; the length of the first support arm 11 may be less than the length of the second support arm 12. This allows the first support arm 11 to be completely fastened to the front of the second support arm 12 after being retracted, which is more convenient for product packaging and transportation.

[0045] See Figures 7 to 10 The upper end of the second support arm 12 is hinged to one end of the first support arm 11. The first support arm 11 has a top water channel 112 that connects to the top spray connection port 111 to supply water to the top spray 50. In this embodiment, the upper end of the second support arm 12 is hinged to one end of the first support arm 11. The first support arm 11 can be bent downwards and folded or flipped downwards and opened relative to the second support arm 12, and maintained at a predetermined angle to achieve position adjustment of the top spray 50.

[0046] The second support arm 12 has a protruding water inlet seat 121 on the upper rear side. The water inlet seat 121 is used to connect to the wall water inlet pipe (not shown) to supply water to the shower support arm assembly. At the same time, the shower support arm assembly in this embodiment can be connected and fixed to the wall only through the water inlet seat 121, and thus maintain the distance between the assembly and the wall, making installation simple and convenient.

[0047] The second support arm 12 is also provided with a water inlet channel 122, a water channel switching chamber 123, a first water channel 124, and a second water channel 125. The water inlet channel 122 connects the water inlet seat 121 and the water channel switching chamber 123. The water channel switching chamber 123 is located at the lower part of the second support arm 12 and is equipped with a switching control valve 126. The switching control valve 126 rotates to control the water channel switching chamber 123 to simultaneously or selectively connect the first water channel 124 and the second water channel 125. The first water channel 124 connects upward to the top water channel 112. The second water channel 125 connects to the lower water outlet 127 located at the lower part of the second support arm 12.

[0048] The lower water outlet 127 can be connected to the shower head 40 fixed on the adjusting seat 20 via a hose 60. Therefore, in this embodiment, the shower arm assembly can switch the connection between the water inlet channel 122 and the first water channel 124 or the second water channel 125 via a switching control valve 126 located at the lower part of the second arm 12, thus enabling either the overhead spray 50 or the shower head 40 to output water. Furthermore, the switching control valve 126 can control both the overhead spray 50 and the shower head 40 to output water simultaneously. Because the switching control valve 126 is located at the lower part of the second arm 12, switching is more convenient and easier, making it more suitable for shorter individuals.

[0049] Furthermore, in this embodiment, waterways are formed within the second arm 12 and the first arm 11, which eliminates the need for most external pipe fittings, resulting in a simpler, more aesthetically pleasing, and more practical appearance.

[0050] The first waterway 124 and the top waterway 112 can be connected through the hinge end of the first arm 11 and the second arm 12. The internal structure of the hinge end can refer to the prior art, and its specific structure will not be described in detail here.

[0051] like Figure 8 and Figure 9 The second support arm 12 may include a front housing 13, an adjustment trough bottom plate 14, a waterway connecting plate 15, a waterway connecting part 16, and a rear cover plate 17.

[0052] The front housing 13 has an adjustment groove 30 on its front side, and the adjustment groove 30 is closed by a bottom plate 14 on its rear side. The bottom plate 14 can be connected by screws. The rack 31 can be integrally formed on the left and right sides of the adjustment groove 30, and then fixed in the adjustment groove 30 to form a fixing member.

[0053] The water channel connecting plate 15 and the water channel connecting part 16 are installed vertically connected on the front side of the rear cover plate 17. The rear cover plate 17 covers the rear side of the front housing 13 and covers the water channel connecting plate 15 and the water channel connecting part 16. The water channel connecting plate 15 and the water channel connecting part 16 can be welded to the rear cover plate 17 to ensure the sealing of the formed water channel.

[0054] Specifically, two vertically extending and horizontally separated upper water inlet channels 1221 and upper first water channel 1241 can be formed between the rear cover plate 17 and the water channel connecting plate 15; two vertically extending and horizontally separated lower water inlet channels 1222 and lower first water channel 1242 can be formed between the rear cover plate 17 and the water channel connecting part 16; the upper water inlet channel 1221 and the lower water inlet channel 1222 are connected to form the water inlet channel 122, and the upper first water channel 1241 and the lower first water channel 1242 are connected to form the first water channel 124; by setting independent water channel connecting plates 15 and water channel connecting parts 16, the production and assembly of the product can be facilitated, and internal connecting pipes can be eliminated, resulting in fewer product assembly steps and higher production efficiency.

[0055] The waterway connection portion 16 is further provided with the waterway switching cavity 123 and the second waterway 125 located below the waterway switching cavity 123; the waterway switching cavity 123 has a first hole 1231, a second hole 1232, and a third hole 1233 respectively connecting the lower water inlet waterway 1222, the lower first waterway 1242, and the second waterway 125, wherein the second hole 1232 and the third hole 1233 are spaced apart along the circumference of the waterway switching cavity 123 (see reference). Figure 10 ).

[0056] The switching control valve 126 includes a valve body 1261 and a switching switch 1262. The valve body 1261 is rotatably mounted on the waterway switching chamber 123. The switching switch 1262 is mounted on the surface of the second support arm 12 and connected to the valve body 1261. The peripheral wall of the valve body 1261 has a sealing part 1263 that can be used to block the second hole 1232 and the third hole 1233.

[0057] Therefore, by rotating the switch 1262, the valve body 1261 can be rotated, thereby allowing the sealing part 1263 to selectively block the second hole 1232 or the third hole 1233, or simultaneously open the second hole 1232 and the third hole 1233, so that the second hole 1232 and the third hole 1233 can be connected to the first hole 1231 simultaneously or selectively. This allows for the selective opening of the water inlet channel 122, the first water channel 124, the top water channel 112, the top spray connection port 111 and the top spray 50, or the opening of the water inlet channel 122, the second water channel 125, the lower outlet 127, the hose 60 and the shower head 40. This can be switched according to the user's needs, making it convenient to use.
