Description

Technical Field

[0001] This invention relates to the field of shower equipment, and more particularly to an integrated shower arm for connecting an overhead shower and a handheld shower head. Background Technology

[0002] like Figure 1 A conventional patent discloses an integrated shower arm (US12269049B1), whose arm body 1 includes a housing 101, a faceplate 102, and a water-passing plate 103. The upper side of the faceplate 102 is fitted with a first water-passing interface 12 for connecting to an overhead shower, and the lower side of the faceplate 102 is fixed with a shower head fixing seat 3. According to the specific embodiment disclosed in this patent document, the shower head fixing seat 3 is magnetically attached to a handheld shower head. A diverter seat 11 is provided in the middle of the housing 101, and the diverter seat 11 has a diverter cavity 112. The valve core body 21 of the diverter valve core 2 is rotatably inserted into the diverter cavity 112, and a second water-passing interface 211 for connecting to a handheld shower head is provided at one end of the valve core body 21. By rotating the diverter valve core 2, the inlet 111 of the diverter seat 11 can selectively connect to the first water-passing interface 12 and / or the first water-passing interface 12. Alternatively, the second water inlet 211 can be connected to the water path. With this structure, the diverter seat 11 is located in the middle of the housing 101. Since the inlet 11 of the diverter seat 11 is used to connect with the water outlet pipe installed on the wall, the diverter seat 11 is relatively high off the ground. The diverter valve core 2 is located on the diverter seat 11, and its switching handle 24 is located on the side of the housing 101 opposite to the face cover 102. When the user stands below the shower arm, their line of sight to observe the handle 24 is easily blocked by the arm 1, which is not conducive to rotating the handle 24. Furthermore, since the diverter valve core 2 is relatively high off the ground, it is inconvenient for children or people of short stature to use.

[0003] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0004] The primary objective of this invention is to provide a top spray arm with a shower head mounting base, which facilitates water path switching for the user.

[0005] The second objective of this invention is to provide a top spray arm that, while satisfying the first objective, is additionally equipped with a water inlet filtration function.

[0006] To achieve the first objective of this invention, this application discloses a top spray arm with a shower head mounting base, which includes: An arm has a water inlet connector at its rear, which is used to connect to a wall-mounted water outlet pipe, so that the arm is vertically installed on the water outlet pipe. The top of the arm has a first water outlet connector for connecting to the top sprayer, and its bottom forms an installation cavity that opens downward and forward. A body is fixed in the mounting cavity. The top of the body is provided with a first water inlet and a second water inlet, and the bottom is provided with a second water outlet connector. A water circuit switching valve core is provided between the first water inlet, the second water inlet and the second water outlet connector. A shower head fixing seat is provided at the front of the body for placing a handheld shower head. An actuating element is located on the side of the support arm and connected to the water circuit switching valve core. The inner cavity of the support arm also forms a first water passage and a second water passage. One end of the first water passage is connected to the water inlet connector water passage, and the other end is connected to the water passage of the first water outlet. One end of the second water passage is connected to the water passage of the first water outlet connector, and the other end is connected to the water passage of the second water outlet. This allows water flowing in through the water inlet connector to flow into the first water outlet through the first water passage. By driving the water passage switching valve core through the actuator, the first water outlet can be selectively connected to the water passage of the second water outlet or the second water outlet connector, or the first water outlet can be simultaneously connected to the water passages of the second water outlet and the second water outlet connector.

[0007] With the above structure, the actuator is located on the lower side of the support arm, which is low to the ground and the user's line of sight is not easily obstructed by the support arm, making it convenient for the user to operate the actuator and thereby drive the water circuit switching valve core to achieve water circuit switching of the support arm.

[0008] To achieve the second objective of this invention, this application also discloses that the support arm is connected in series with a filter element in the first water passage, so that the water flowing into the first water passage through the first water inlet is filtered by the filter element, thereby effectively removing harmful impurities in the water and making the water used during showering healthier and safer.

[0009] In one embodiment, the support arm consists of a front housing and a rear housing, both with hollow interiors. A horizontally positioned cylindrical body is located at the rear of the rear housing. One end of the cylindrical body is open, and the other end is closed. A water-separating plate is positioned on the closed end side of the cylindrical body, forming a first water-receiving chamber between the water-separating plate and the closed end of the cylindrical body. The water-separating plate has at least one first water passage hole. The filter element is housed within the cylindrical body through the open end, with its end facing the water-separating plate being the water inlet and the other end being the water outlet. A screw cap seals the open end of the cylindrical body, defining the space within the cylindrical body for housing the filter element as a second water-receiving chamber. The second water-receiving chamber has a second water passage hole on its pipe wall. The rear housing also has a water inlet channel, one end of which connects to the second water passage hole, and the other end connects to the first water inlet interface. The water inlet connector protrudes from the outer wall of the cylindrical body on the side opposite to the front housing. Water flowing in through the water inlet connector flows through the first water-receiving chamber to the inlet end of the filter element, then flows out from the outlet end of the filter element to the second water-receiving chamber, flows through the second water passage hole into the water inlet channel, and then into the first water inlet interface. The first water-receiving chamber, the first water passage hole of the baffle plate, the second water-receiving chamber, the second water passage hole, and the water inlet channel together constitute the first water inlet channel. This structure facilitates quick replacement of the filter element on the support arm. Attached Figure Description

Detailed Implementation

[0011] In the description of this invention, it should be understood that the terms "front" and "rear" are consistent with the orientation in the drawings, but are only for the convenience of describing the invention and enabling those skilled in the art to better understand the relative positional relationship between the components when reading the specification, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0012] like Figure 4a This application discloses a top spray arm 100 with a shower head mounting base, which includes an arm 1, a base 2, and an actuating member 3. The top free end of the arm 1 protrudes forward to facilitate the installation of a first water outlet connector 14 at the top free end of the arm 1. The shape of the arm can be an arc-shaped curved arm as disclosed in conventional art (US12269049B1), but in this embodiment, the arm 1 adopts an angular design style, with a forward-leaning vertical section 116 at the lower part and a forward-facing bent section 117 at the upper part, forming an angle α between the vertical section 116 and the bent section 117 of the arm 1. The angle α is in the range of 90°≤α≤150° (e.g., ...). Figure 6aThe bottom of the support arm 1 forms an installation cavity that opens downwards and forwards. The seat 2 is fixed in the installation cavity, and a second water outlet connector 23 is provided at the bottom. A shower head fixing seat 25 is provided at the front of the seat 2. The shower head fixing seat can adopt a magnetic attraction structure similar to that disclosed in conventional technology (US12269049B1), that is, the shower head fixing seat and the matching handheld shower head are respectively provided with magnetic material and magnetic attraction material, or the handheld shower head and the shower head fixing seat are connected by magnetic attraction principle by providing positive and negative magnetic materials on both (not shown in the figure); or the structure of the shower socket (also known as the shower wall mount) disclosed in this embodiment of the shower head fixing seat 25 can be adopted, and its specific structure can be referred to Patent document CN215858027U discloses that the shower socket can be angle-adjustable. If the shower holder 25 adopts a magnetic structure or the shower socket can be angle-adjustable, a recessed portion 111 is formed on the front end face of the vertical section 116 of the support arm 1, above the shower holder 25. The depth of the recessed portion 111 matches the thickness of the handheld shower head 5. Therefore, when the handheld shower head 5 is placed in the recessed portion 111, its front end face is basically flush with the front end face of the vertical section 116 of the support arm 1 outside the recessed portion 111, making the overall shape of the top spray support arm 100 assembly constructed with the handheld shower head 5 more minimalist and aesthetically pleasing. Taking the shower holder 25 with an adjustable angle shower socket structure as an example, such as... Figure 4c When it is necessary to remove the handheld shower head 5 from the shower head holder 25, the handheld shower head 5 inserted in the shower head holder 25 should first be rotated forward so that its top is misaligned with the top of the sinking part 111 of the support arm 1. Then, it can be pulled out of the shower head holder 25. To facilitate the removal of the handheld shower head 5 from the sinking part 111 of the support arm 1, a notch 112 can be provided on the left and right sides of the sinking part 111 of the support arm 1. Of course, the support arm 1 with the sinking part 111 disclosed in this invention is the preferred design, but other designs can also be adopted. Figures 3a to 3b The disclosed top spray arm 100a without the sinking part 111 can be used as a socket if the shower head holder 25 adopts a socket structure. The shower head holder 25 can adopt a fixed socket structure or an adjustable angle socket structure. It should also be noted that the handheld shower head 5 disclosed in this embodiment is a flat design. There are also cylindrical handheld shower heads on the market. Therefore, the sinking part of the top spray arm can be designed with a concave arc transition (not shown in the figure) to make the shape of the handheld shower head and the top spray arm more unified and harmonious.

[0013] like Figure 4d-4iAs shown, the support arm 1 is composed of a front housing 11 and a rear housing 12. The front housing 11 is a hollow component with an open rearward orientation, formed by a front panel 113, two first side panels 114, and a top panel 115. Several locking blocks 1141 are provided on the inner walls of the two first side panels 114. The rear housing 12 includes a rear panel 128 and two second side panels 129 forming a hollow component with an open front orientation. The lower part of the two second side panels 129 forms a gap, and the second side panels 129 are provided with locking holes 1291 corresponding to the locking blocks 1141. The two second side panels 129 are covered by the two first side panels 114, so that the locking blocks 1141 and the locking holes 1291 are interlocked and connected, thereby realizing the front housing 11 and the rear housing 12 being spliced ​​and fixed together to form a hollow support arm 1. The bottom of the support arm 1 forms an installation cavity that opens downward and forward. The rear of the rear housing 12 is provided with a horizontally placed cylindrical body 121. The inner cavity of the cylindrical body 121 is hollow and is used to place the filter element 4. The two first side panels 114 of the front housing 11 form an arc-shaped clearance notch 1142 at the position relative to the cylindrical body 121. Of course, if the cylindrical body 121 is set at the rear of the rear panel 128 of the rear housing 12, the arc-shaped clearance notch 1142 of the front housing 11 can be designed by default. To facilitate filter element replacement 4, the cylindrical body 121 has an open end 1211 and a closed end 1212 at one end. A water-separating plate 122 is provided on the side of the cylindrical body 121 located at the closed end 1212, forming a first water-containing chamber I between the water-separating plate 122 and the closed end 1212 of the cylindrical body 121. A first water passage hole 1221 is opened in the middle of the water-separating plate 122. The filter element 4 is inserted into the cylindrical body 121 through the open end 1211, with its end facing the water-separating plate 122 being the water inlet end 41 and the other end being the water outlet end 42. The screw cap 43 closes the open end 1211 of the cylindrical body 121, so that the space in the cylindrical body 121 for placing the filter element 4 is defined as the second water chamber II. A second water passage 123 is opened in the tube wall of the second water chamber II. A water inlet channel 124 is also provided in the inner cavity of the rear housing 12, one end of which is connected to the second water passage 123. In order to prevent water from leaking from the gap between the outer wall of the filter element 4 and the water separator 122, an end face sealing ring 1222 is added between the water separator 122 and the water inlet end 41 of the filter element 4. To facilitate the removal of the filter element 4 from the cylindrical body 121, the cap 43 is interference-fitted with the outer wall of the filter element 4, and several baffles 431 are provided on the inner end face of the cap 43 so that there is sufficient water passage space between the water outlet end 42 of the filter element 4 and the cap 43. When the cap 43 is rotated and pulled out from the opening end 1211 of the cylindrical body 121, the filter element 4 can be pulled out at the same time.A mounting boss 125 is provided on the outer wall of the cylindrical body 121 and on the side away from the front housing 11. A third water passage 1251 is offset from the mounting boss 125. The third water passage 1251 is connected to the water passage of the first water chamber I. The water inlet connector 13 is fixed on the mounting boss 125.

[0014] like Figure 4gThe water inlet connector 13 includes a connector 131, a fixing seat 132, and a water-passing positioning pin 133; the mounting boss 125 has a first countersunk hole 1252 in the middle, and a first fastening hole 1253 is provided in the center of the first countersunk hole 1252; the third water-passing channel 1251 is offset on the side of the first countersunk hole 1252 adjacent to the first water-containing chamber I; the upper part of the fixing seat 132 is also provided with a flange 1322, and the flange 1322 is provided with a plurality of second through holes 1323; the top of the mounting boss 125 is provided with a second fastening hole 1254 corresponding to the position of the second through holes 1323. The second set screws 1255 pass through the corresponding second through holes 1323 and are screwed into the second fastening holes 1254, thereby fixing the fixed seat 132 to the mounting boss 125. The central shaft portion of the fixed seat 132 forms an axially penetrating first through hole 1321, which allows the water-passing positioning pin 133 to pass through. The connector 131 is axially penetrating, with an internal thread section 1311 at its upper part and an inwardly extending bottom edge 1312 at its lower part. The bottom edge 1312 of the connector 131 is placed on the top of the fixed seat 132, and the connector 131 is coaxial with the first through hole 1321. The design includes a first retaining edge 1331 protruding outward from the upper middle part of the outer wall of the water-passing positioning pin 133, with several water-passing grooves 1332 formed in the lower part. The central axis of the water-passing positioning pin 133 has a fourth water-passing channel 1333 connected to an external water source. This fourth water-passing channel 1333 is connected to the third water-passing channel 1251 via the water-passing grooves 1332. A support platform 1334 is provided at the bottom of the water-passing positioning pin 133. The water-passing positioning pin 133 is sequentially inserted into the first through hole 1321 of the connector 131 and the fixing seat 132 until the support platform 1334 abuts against the bottom of the first countersunk hole 1252. A first set screw 134 passes through the support platform 1334 and is screwed into the first fastening hole 1253, thus fixing the water-passing positioning pin 133. The first abutment 1331 of the water-passing positioning pin 133 abuts against the bottom edge 1312 of the connector 131 from top to bottom, thereby fixing the connector 131 to the top of the fixing seat 132. To prevent water leakage from the gap between the water-passing positioning pin 133 and the fixing seat 132, and the gap between the fixing seat 132 and the mounting boss 125, a second O-ring 1336 is fitted onto the water-passing positioning pin 133, and a third O-ring 1324 is fitted onto the fixing seat 132. This design ensures that the relatively heavy overhead shower arm 100 assembly (equipped with an overhead shower and handheld shower head 5) is stably fixed to the water outlet pipe. In a more preferred design, a retaining ring 1335 is provided on the outer wall of the water-passing positioning pin 133 below the first through hole 1321. This can prevent the first set screw 134 from accidentally coming out of the first fastening hole 1253, causing the water-passing positioning pin 133 to be accidentally pulled out of the fixing seat 132, resulting in the support arm 1 accidentally falling off the connector 131.

[0015] like Figure 4hThe top of the base 2 is equipped with a first water inlet 21 and a second water inlet 22, and the bottom is provided with a second water outlet connector 23. The first water inlet 21 is connected to the water passage of the first water passage 15. The third water passage 1251, the first water chamber I, the first water hole 1221 of the baffle plate 122, the second water chamber II, the second water hole 123, and the water inlet channel 124 together constitute the first water passage 15. The second water inlet 22 is connected to the water passage of the second water passage 16. The second water passage 16 disclosed in this embodiment is an independently set flexible hose. Of course, the second water passage 16 is also... It can be directly injection molded in the inner cavity of the rear housing 12 or the front housing 11, but this will increase the manufacturing cost. The seat 2 is provided with a water circuit switching valve core 24 between the first water inlet 21, the second water inlet 22 and the second water outlet connector 23. The water circuit switching valve core 24 includes an installation channel 241 and a valve stem 242. The installation channel 241 is arranged laterally below the seat 2 located below the first water inlet 21 or the second water inlet 22. Its cross-section is circular. The installation channel 241 runs through the seat laterally. One end of the channel is provided with an arc-shaped limiting block 2414 and the other end serves as the insertion end 2415 of the valve stem 242. The valve stem 242 has a connecting block 2421 protruding outward at the end facing the knob 3. The connecting block 2421 is non-circular in shape, with a third fastening hole 2422 in its middle. A stop block 2423 protrudes from the connecting block 2421 along the radial direction of the valve stem 242. Two sealing rings (first O-rings 243) are spaced apart in the middle section of the valve stem 242, and a plug 244 is provided between the first O-rings 243. The valve stem 242 is inserted from the insertion end 2415 of the installation channel 241 until it is restricted by the arc-shaped limiting block 2414, so that the installation channel 241 forms a water collection chamber IV in the space between the two first O-rings 243. At the same time, a first water outlet 2411, a second water outlet 2412, and a third water outlet 2413 are respectively opened on the inner wall of the installation channel 241 in the circumferential direction of the area of ​​the water collection chamber IV. 13. The first water inlet 2411 is connected to the first water inlet 21, the second water inlet 2412 is connected to the second water inlet 22, and the third water inlet 2413 is connected to the second water outlet 23. In a more preferred design, the installation channel 241 has three horizontally opened positioning notches 2416 on the inner wall of the insertion end 2415. The three positioning notches 2416 correspond one-to-one with the second water inlet 2412, the third water inlet 2413, and the inner wall on the side away from the second water inlet 2412. A spring-loaded positioning terminal 245 is set at the corresponding position of the radial end of the valve stem 242. By rotating the knob 3, the valve stem 242 is rotated, so that the positioning terminal 245 can switch between different positioning notches 2416. During the switching process, a positioning sound is emitted to indicate to the user that the knob 3 has been switched to the correct position.

[0016] like Figure 4f The rear housing 12 has four downwardly extending threaded posts 126 protruding below the outer wall of the cylindrical body 121. The bottom of the base 2 has four positioning through holes 29 corresponding to the threaded posts 126. Four fourth set screws 291 pass through the positioning through holes 29 and are locked to the threaded posts 126, thus fixing the base 2 to the rear housing 12. Preferably, the inner wall of the rear panel 128 of the rear housing 12 has two guide positioning plates 127 protruding vertically forward in the mounting cavity area. The rear part of the base 2 is recessed from top to bottom to form a limiting groove 30. This limiting groove 30 can be designed as a single downwardly recessed groove (e.g., ...). Figure 4h Alternatively, it can be designed as two vertical limiting tracks (not shown) that intersect with the guide positioning plate 127. The seat 2 forms a guide positioning with the two guide positioning plates 127 in the vertical direction through the limiting groove 30, thereby ensuring that the four positioning through holes 29 of the seat 2 accurately intersect with the four screw posts 126. At the same time, since the two second side panels 129 of the rear housing 12 have open sections, the rear panel 128 can also further improve its structural strength by setting the guide positioning plate 127 in the open section area.

[0017] like Figure 4f , 6b The second water outlet connector 23 and the base 2 are designed as separate units. The second water outlet connector 23 consists of a connecting post 231 and an interface part 232 from top to bottom. The inner cavities of the connecting post 231 and the interface part 232 are interconnected. The upper section of the connecting post 231 has two annular protrusions 2311 spaced apart on its outer peripheral wall, which are defined as limiting sections 2312. The interface part 232 is equipped with an external thread section. The bottom of the base 2 is provided with an insertion hole 26, and a third water-receiving chamber III is formed between the insertion hole 26 and the third water outlet 2413. A hollow part 27 is opened on the side of the base 2 and located in the third water-receiving chamber III. The sealing side cover 28 has a U-shaped insert 281 extending towards the third water chamber III. The connecting post 231 is inserted through the insertion hole 26 and extends into the third water chamber III. The sealing side cover 28 seals the hollow portion 27 by ultrasonic welding, and the U-shaped insert 281 abuts against the limiting section 2312 of the connecting post 231. The U-shaped insert 281 is vertically and vertically limited by the two annular protrusions 2311, thereby fixing the second water outlet connector 23 to the bottom of the base body 2. To prevent water from leaking outward from the gap between the second water outlet connector and the insertion hole 26, a fourth O-ring seal 2314 is fitted on the connecting post 231. The above design facilitates the injection molding of the complex base body 2 and reduces manufacturing costs.

[0018] The actuating element 3 is a knob 3 with a handle. The knob 3 has a second countersunk hole 31 at its center. A third through hole 32 is formed in the middle of the second countersunk hole 31. A sleeve 33 protrudes from the second countersunk hole 31 towards the valve stem 242. The sleeve 33 of the knob 3 passes through the fourth through hole 1143 of one of the first side panels 114 of the front housing 11 and is fitted onto the connecting block 2421 of the valve stem 242. A third set screw 34 passes through the third through hole 32 of the second countersunk hole 31. 2. It is screwed into the third fastening hole 2422 to realize the fixed connection between the knob 3 and the valve stem 242. By rotating the knob 3, the valve stem 242 is driven to rotate synchronously, so that the plug 244 of the valve stem 242 selectively blocks the second water outlet 2412 or the third water outlet 2413, or the plug 244 is placed on the inner wall of the installation channel 241. At the same time, the stop block 2423 of the knob 3 is mutually limited with the two ends of the arc-shaped limit block 2414, thereby controlling the rotation angle range of the knob 3.

[0019] The following combination Figures 5b to 8b This is used to illustrate the working principle of the top spray support arm 100: External water flows in through connector 131, passing sequentially through the fourth water passage 1333 of water passage positioning pin 133, water passage groove 1332, the third water passage 1251 of mounting boss 125, and the first water chamber I. The water flows into the inlet 41 of filter element 4, and then out from the outlet 42 of filter element 4 to the second water chamber II. It then flows into the water collection channel 124 through the second water passage hole 123. The external water source can effectively filter impurities harmful to the human body through filter element 4, thus effectively purifying the water quality. The purified water flows into the water collection chamber IV of mounting channel 241 through the first water passage interface 21 of base 2. Figure 6a , 6b When knob 3 is in the first position, the plug 244 of valve stem 242 blocks the second water outlet 2412, and the water in the water collection chamber IV can only be discharged through the third water outlet 2413. The water flows through the third water chamber III to the second water outlet 23 and is connected to the water path of the handheld shower head 5 via a hose. At this time, the handheld shower head 5 sprays water outward. Figure 7a , 7b When knob 3 is rotated 90 degrees clockwise to the second position, the plug 244 of valve stem 242 blocks the third water outlet 2413, and the water in the water collection chamber IV can only be discharged through the second water outlet 2412. The water flows through the second water passage 16 and connects with the water path of the first water outlet connector 14.
