Description
Technical Field
[0001] This application relates to the field of bathroom equipment, and in particular to a high-pressure overhead shower head with an easy-to-replace filter cartridge. Background Technology
[0002] With the improvement of living standards, shower equipment has become increasingly important in daily life, and people's demands for it are also rising. Shower equipment must not only meet basic water output functions, but also consider factors such as water output effect and ease of use, which directly affect the user's showering experience. As one of the most common shower equipment, the overhead shower head with easy-to-replace filter plays an important role in the bathroom equipment field, and continuous improvement and optimization of this type of shower head is of positive significance for improving people's quality of life. In related technologies, specific connection devices are often used to solve the problems of filter replacement and component connection in overhead shower heads. For example, a replaceable filter shower head is disclosed, the shower head body is composed of an upper shell and a water output component, which are detachably connected by a connection device. This connection device consists of a spring clip, a retaining ring, a button, and a return spring. The upper shell is a hollow, downward-facing cover with a water inlet at the top. A ball head seat is formed around the water inlet for installing a universal ball joint, and a button seat is provided on the side wall for installing the button of the connection device. The inner surface of the button seat has a groove for engaging with the spring clip and a retaining ring seat for installing the retaining ring. The water outlet assembly has a hollow flange with an open top. A water filter assembly is installed in the hollow part of the flange, and the outer wall is formed by an annular groove with arc-shaped slots for installing spring clips. The bottom has a water outlet panel with several water outlet holes, and the bottom of the flange has a water passage hole communicating with the water outlet panel. The spring clip of the connecting device is movably installed in the arc-shaped groove of the annular groove of the water outlet assembly. The button is installed in the button seat of the upper housing via a retaining ring, forming a fit with the spring clip. However, the existing connecting device has significant drawbacks. On the one hand, its complex structure and numerous parts make assembly and maintenance very inconvenient, increasing labor and time costs. On the other hand, the fit between the spring clip and the retaining ring is prone to fatigue failure during long-term use, resulting in poor connection stability. When high-pressure water flow is introduced, the spring clip is prone to loosening or even breaking from the retaining ring, affecting the reliability of the product connection and impacting the normal use of the overhead shower. Furthermore, the filter replacement process in traditional designs is cumbersome, requiring the disassembly of multiple parts, significantly reducing the user experience. Summary of the Invention
[0003] In order to improve the replacement efficiency of the filter element, enhance the stability of the connection structure of the overhead shower head, and thus improve the high pressure resistance of the shower head to water flow, this application provides a high pressure overhead shower head that facilitates filter element replacement.
[0004] This application provides a high-pressure overhead shower head with an easy-to-replace filter element, comprising a housing, a filter element, and a clamping device. The housing includes a top cover and a bottom cover. The water inlet end of the housing is provided with a water inlet mechanism, which includes a positioning element. The top cover is detachably fitted onto the positioning element, and the positioning element is detachably connected to the bottom cover. The filter element is disposed within the positioning element. The clamping device includes at least one clamping mechanism and at least one unlocking mechanism. The clamping mechanism includes a first limiting boss and a second limiting boss. The first limiting boss protrudes from the outer wall of the positioning element, and the second limiting boss protrudes from the inner wall of the bottom cover. The second limiting boss slides against the top of the first limiting boss. The unlocking mechanism is movably engaged with the first limiting boss. When the unlocking mechanism releases the restriction on the first limiting boss, rotating the positioning element releases the connection between the positioning element and the bottom cover. By adopting the above technical solution, since the top cover is detachably fitted onto the positioning component via the mounting component, and the positioning component is detachably connected to the bottom cover, and the filter device is located inside the positioning component, when the filter element needs to be replaced, it is only necessary to first operate the unlocking mechanism to release the restriction on the first limiting boss, thereby releasing the restriction on radial displacement between the positioning component and the bottom cover. Then, rotating the positioning component will release the connection between the positioning component and the bottom cover, and the top cover can be removed from the positioning component, making it easy to replace the filter element inside the filter device. Unlike traditional designs, it does not require disassembling multiple parts, greatly simplifying the filter element replacement process, improving filter element replacement efficiency, and enhancing the user experience. Utilizing the cooperation of the first and second limiting bosses of the clamping mechanism, the second limiting boss slides against the top of the first limiting boss, restricting vertical displacement between the positioning component and the bottom cover. This structure is simpler than existing connecting device structures, reduces the number of parts, and makes assembly and maintenance more convenient. Moreover, this matching method can effectively improve the stability of the connection and avoid the fatigue failure problem caused by long-term use of the spring clip and snap ring matching method. This enhances the shower head's high pressure resistance to water flow. Even when high pressure water flow is introduced, the reliability of the connection between the positioning component and the base cover can be guaranteed, thus improving the reliability of the product connection.
[0005] Preferably, the first limiting boss is provided with a limiting groove, and the unlocking mechanism is movably embedded in the limiting groove. By adopting the above technical solution, the first limiting boss is provided with a limiting groove, and the unlocking mechanism is movably embedded in the limiting groove. In this way, when the unlocking mechanism is in the normal embedded state, it can effectively prevent the positioning member and the bottom cover from rotating arbitrarily, so that the positioning member and the bottom cover maintain a stable connection. Because the limiting groove plays a clear limiting role on the unlocking mechanism, it restricts the range of motion of the unlocking mechanism, thereby ensuring the stability of the entire connection structure. Moreover, when the filter element needs to be replaced, it is only necessary to operate the unlocking mechanism to disengage it from the limiting groove, and the positioning member can be easily rotated to release the connection between the positioning member and the bottom cover, realizing quick replacement of the filter element and effectively improving the replacement efficiency of the filter element. Preferably, the ends of the first limiting boss and the second limiting boss are respectively provided with a first arc-shaped guide portion and a second arc-shaped guide portion, and the first arc-shaped guide portion slides along the second arc-shaped guide portion into the other end of the second limiting boss. By adopting the above technical solution, the first and second arc-shaped guide portions at the ends of the first and second limiting bosses serve a guiding function during the connection of the top and bottom covers due to their smooth curved shape. The first arc-shaped guide portion can slide smoothly along the second arc-shaped guide portion, avoiding rigid collisions and jamming, making the connection between the top and bottom covers easier and more accurate, and improving assembly efficiency. Simultaneously, this sliding fit allows the first limiting boss to smoothly slide into the other end of the second limiting boss, achieving a stable connection and enhancing the stability of the connection between the top and bottom covers. Moreover, this connection method reduces wear during the connection process, extends the service life of components, and further improves the overall high-pressure resistance of the top spray shower head to water flow, reducing the possibility of loosening or damage under high-pressure water flow impact due to unstable connection. Preferably, both the first and second limiting bosses are provided with several air chambers.
[0006] By adopting the above technical solution, both the first and second limiting bosses are provided with several air chambers. These air chambers act as a buffer, helping to maintain a stable fit between the first and second limiting bosses and preventing misalignment or loosening due to water flow impact, thereby improving the stability of the overhead shower head connection structure. Simultaneously, the presence of the air chambers facilitates sliding between the first and second limiting bosses, preventing the positioning component and the base cover from being too tightly fitted, requiring excessive force to rotate. Preferably, the unlocking mechanism includes a first rotating component and a button. The first rotating component is rotatably connected to the base cover, and its end is movably engaged in the limiting groove. The button slides with the base cover to drive the end of the first rotating component to rotate. By adopting the above technical solution, the unlocking mechanism includes a first rotating component and a button. The first rotating component is rotatably connected to the base cover and its end is movably engaged in the limiting groove. The button slides with the base cover to drive the end of the first rotating component to rotate. When a user needs to disconnect the positioning component from the base cover to replace the filter element, they simply press the button, causing it to slide on the base cover. The movement of the button drives the end of the first rotating component to rotate, thus disengaging it from the limiting groove. This releases the unlocking mechanism from the first limiting boss. This simple operation avoids the cumbersome process of disassembling multiple components required in traditional complex connection devices, simplifying the filter element replacement process and significantly improving replacement efficiency. Preferably, the first rotating component includes a rotating shaft, a driving block, a driven block, and a linkage block. One end of the driving block is fixedly connected to the rotating shaft, and one end of the driven block is also fixedly connected to the rotating shaft. The linkage block is fixedly connected to the end of the driven block away from the rotating shaft, and the driven block is movably engaged within the limiting groove. By adopting the above technical solution, the first rotating component includes a rotating shaft, a driving block, a driven block, and a linkage block. The driving block is fixedly connected to the rotating shaft, the driven block is also fixedly connected to the rotating shaft, and the linkage block is fixedly connected to the end of the driven block away from the rotating shaft, thus forming a stable linkage structure. When the button drives the first rotating component, the rotating shaft, acting as the central axis, drives the active block to rotate. Since both the active and driven blocks are fixed on the rotating shaft, the rotation of the active block is transmitted to the driven block through the rotating shaft, thereby driving the linkage block to move. The driven block is movably engaged in the limiting groove. This stable linkage allows the first rotating component to accurately engage and disengage from the limiting groove. Compared to existing complex and fatigue-prone connection devices, this structure is simpler and more precise, avoiding loosening problems caused by poor component fit, and greatly improving the connection stability and reliability of the connection device. Preferably, it also includes a gear adjustment device, which is located inside the base cover and below the positioning component. The gear adjustment device is used to adjust the water pressure.By adopting the above technical solution, a pressure adjustment device is installed inside the bottom cover and below the positioning member. Since the water flow enters from the inlet of the housing device and flows downwards through the positioning member, the pressure adjustment device at this location can promptly intercept and act on the water flow. When different sizes of water flow pass through, the pressure adjustment device can change the internal channel structure or flow area as needed, thereby adjusting the water pressure. This provides users with diverse water pressure options to meet different showering needs, such as gentle massage water pressure or strong rinsing water pressure, greatly improving the user's showering experience. Preferably, the filtration device includes a filter element, a first sleeve, and a second sleeve, all disposed within the top cover. One end of the filter element is installed in the first sleeve, and the other end is installed in the second sleeve. After the water flows into the water inlet mechanism along the inlet of the housing device, it flows sequentially through the first sleeve, the filter element, and the second sleeve to the pressure adjustment device, where the water pressure is adjusted before being sprayed out.
[0007] By adopting the above technical solution, water flows into the water inlet mechanism from the inlet end of the housing device, and first enters the first sleeve. The first sleeve guides the water flow initially, ensuring it flows orderly towards the filter element. Next, the water flows through the filter element, which filters impurities in the water, effectively removing potentially harmful substances such as sediment and rust, thus improving water cleanliness. The filtered water then enters the second sleeve, which further stabilizes the water flow, ensuring it flows more evenly towards the pressure adjustment device. Finally, the pressure adjustment device regulates the water pressure, satisfying the different water pressure requirements of various users and ensuring a stable and suitable water output even under high pressure, thereby enhancing the user's showering experience. In summary, this application includes at least one of the following beneficial technical effects: 1. Since the clamping device only includes at least one clamping mechanism and at least one unlocking mechanism, the structure is simpler and the number of parts is fewer. Therefore, by setting up the clamping device, the connection structure is simplified, the number of parts is reduced, and assembly and maintenance are more convenient. 2. The first limiting boss protrudes from the outer wall of the positioning component, and the second limiting boss protrudes from the inner wall of the bottom cover. The two slide against each other, and at the same time, the unlocking mechanism is movably engaged with the first limiting boss. This multi-limiting method is more stable than the existing single engagement method of spring clip and retaining ring, and can withstand greater external force. Therefore, by utilizing the sliding contact of the first and second limiting bosses and the movable engagement of the unlocking mechanism, the connection stability is enhanced, the resistance of the top spray shower head to high-pressure water flow is improved, and the connection is prevented from loosening or breaking. 3. Because it is only necessary to release the restriction of the first limiting boss by the unlocking mechanism and then rotate the positioning part to release the connection between the positioning part and the bottom cover, there is no need to disassemble multiple parts as in the traditional design, thus simplifying the filter replacement process and improving replacement efficiency.

Detailed Implementation
[0020] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.
[0021] This application provides a high-pressure overhead shower head with an easy-to-replace filter element, comprising a housing assembly and a filter device, a speed adjustment device, and a clamping device disposed on the housing assembly.
[0022] In this embodiment, the housing device 1 includes a top cover 11 and a bottom cover 12. (Refer to...) Figure 1 and Figure 2 The top cover 11 has a water inlet at its top for introducing water flow, while the bottom cover 12 has multiple first water outlets 124 distributed at its bottom for evenly spraying water. The top cover 11 and the bottom cover 12 are detachably connected for easy internal cleaning and maintenance by the user.
[0023] Specifically, a filter device 2 and a speed adjustment device 3 are installed inside the housing 1. The filter device 2 is installed inside the top cover 11, and its main function is to intercept impurities and particulate matter in the water, ensuring water cleanliness and hygiene, thereby protecting the user's skin health. The speed adjustment device 3 is located inside the bottom cover 12, and it is a key component for controlling the water flow rate and spray pattern. Users can adjust the settings of the speed adjustment device 3 according to their preferences and needs to change the strength of the water flow and the spray pattern, thereby achieving a more personalized shower effect.
[0024] In this embodiment, the housing device 1 has a drainage channel inside. The drainage channel serves as a key link connecting the filter device 2 and the speed adjustment device 3. One end of the drainage channel is precisely connected to the water inlet to ensure seamless water entry. The other end of the drainage channel is precisely connected to the water outlet, allowing the filtered and adjusted water to flow out smoothly and efficiently, providing users with an ultimate bathing experience.
[0025] Continue to refer to Figure 2 The top cover 11 has a water inlet mechanism 13 located inside the end near the water inlet. The water inlet mechanism 13 includes a mounting ring 131 and a positioning element 132. Specifically, the mounting ring 131 is located inside the top cover 11, and its end near the water inlet is integrally formed with the inner wall of the top cover 11, creating a water inlet channel connected to the water inlet. Both ends of the mounting ring 131 are open, and its top end communicates with the water inlet. The positioning element 132 is threaded into the mounting ring 131, increasing the ease of installation and removal for workers.
[0026] Reference Figure 2 and Figure 4The positioning component 132 includes a first connecting cylinder 1321, a positioning cylinder 1322, and a connecting ring 1323. Both ends of the first connecting cylinder 1321 and the positioning cylinder 1322 are open, and the connecting ring 1323 is annular. The bottom end of the first connecting cylinder 1321 is integrally formed with the upper surface of the connecting ring 1323, and the top end of the positioning cylinder 1322 is integrally formed with the lower surface of the connecting ring 1323. The diameter of the first connecting cylinder 1321 is smaller than the diameter of the positioning cylinder 1322. A first water inlet hole is formed at the center of the connecting ring 1323. The diameter of the inner wall of the connecting ring 1323 is the same as the diameter of the first water inlet hole, and the diameter of the outer wall of the connecting ring 1323 is the same as the diameter of the outer wall of the positioning cylinder 1322. The filter device 2 is installed inside the positioning cylinder 1322. The outer wall of the positioning cylinder 1322 is integrally formed with a connecting ring 1323. The bottom end of the top cover 11 is connected to the positioning cylinder 1322 by a snap-fit engagement, thereby increasing the overall structural strength of the top cover 11.
[0027] Reference Figure 2 Furthermore, the water inlet mechanism 13 in this embodiment also includes a water inlet valve 133. The inner wall of the water inlet valve 133 has a water inlet channel 1331, one end of which extends to the outside, and the other end of which communicates with the first water inlet hole 1325. The water inlet valve 133 includes a second connecting cylinder 1332 and a ball head seat 1333. The bottom end of the second connecting cylinder 1332 and the top end of the ball head seat 1333 are integrally formed. The water inlet channel 1331 extends through both the second connecting cylinder 1332 and the ball head seat 1333. The ball head seat 1333 is fixed inside the mounting ring 131. The second connecting cylinder 1332 is located outside the top cover 11. The inner wall of the second connecting cylinder 1332 has an internal thread for threaded connection with external connectors (such as water pipes) to achieve water input.
[0028] Continue to refer to Figure 2 The mounting ring 131 has a first clamping member 134 inside, and the inner wall of the second connecting cylinder 1332 has a second clamping member 135. The ball head seat 1333 is located between the first clamping member 134 and the second clamping member 135. The first clamping member 134 and the second clamping member 135 clamp the ball head seat 1333, thereby fixing the water inlet valve 133 to the water inlet end of the top cover 11. The first clamping member 134 and the second clamping member 135 are both annular, and the side of the first clamping member 134 and the second clamping member 135 near the ball head seat 1333 is provided with an arc-shaped groove, thereby increasing the contact area between the first clamping member 134 and the second clamping member 135 and the ball head seat 1333, thereby increasing the firmness of the installation of the water inlet valve 133. Meanwhile, the inner wall of the water inlet channel 1331 is integrally formed with a limiting ring 136, which abuts against the bottom end of the second clamping member 135, thereby further increasing the firmness of the first clamping member 134 and the second clamping member 135 in clamping the ball head seat 1333.
[0029] The filter device 2 includes a filter element 21, a first sleeve 22, and a second sleeve 23. The filter element 21 is cylindrical. The first sleeve 22 and the second sleeve 23 are respectively sleeved on both ends of the filter element 21. Both the first sleeve 22 and the second sleeve 23 are fixed to the filter element 21. The first sleeve 22 is fixed to the inner side wall of the connecting ring 1323, thereby realizing the installation of the filter device 2 inside the top cover 11.
[0030] Reference Figure 5 and Figure 6 The outer wall of the first sleeve 22 is integrally formed with multiple annular first flanges 221, which are spaced apart along the length of the axis. Simultaneously, the inner walls of the positioning cylinder 1322 and the connecting ring 1323 are provided with multiple L-shaped second flanges 231 arranged circumferentially. The outer walls of the first flanges 221 abut against the outer walls of the second flanges 231, ensuring the gap between the filter device 2 and the positioning member 132, and ensuring unobstructed water flow. A second water outlet 233 is provided at the center of the second sleeve 23, allowing water to pass through the filter element 21 and then be smoothly transported to the gear adjustment device 3 via the drainage channel.
[0031] Reference Figure 2 and Figure 3 The bottom cover 12 includes a support ring 121, a cover body 122, and a water outlet panel 123. The top of the cover body 122 is integrally formed with the support ring 121. The water outlet panel 123 is detachably connected to the bottom of the cover body 122, which increases the ease of installation and removal of the water outlet panel 123 by the operator. The water outlet panel 123 has multiple first water outlet holes 124. The bottom of the top cover 11 is open and abuts against the top of the bottom cover 12. The bottom cover 12 is provided with a clamping device 4 for clamping and fixing the top cover 11, which increases the convenience of installation and removal of the top cover 11 by the operator, thereby increasing the convenience of replacement of the filter device 2 by the operator.
[0032] Reference Figure 3 and Figure 4The clamping device 4 includes two clamping mechanisms 41 and two unlocking mechanisms 42, with the two clamping mechanisms 41 being symmetrical to each other. Each clamping mechanism 41 includes a first limiting boss 411 and a second limiting boss 412. The first limiting boss 411 protrudes from the outer wall of the positioning member and is provided with a rectangular limiting groove 4111. The positioning member is integrally formed with the first limiting boss 411 to form the rectangular limiting groove 4111. The second limiting boss 412 protrudes from the inner wall of the bottom cover. The second limiting boss 412 is integrally formed with the bottom cover, and its shape matches that of the first limiting boss 411 so that it can slide and abut well. The second limiting boss 412 slides and abuts against the top of the first limiting boss 411. This abutting method can ensure that the relative position of the positioning member and the bottom cover in the circumferential direction is fixed, thereby achieving a stable connection between the top cover 11 and the bottom cover 12.
[0033] Continue to refer to Figure 4 The first limiting boss 411 and the second limiting boss 412 are respectively provided with a first arc-shaped guide portion 4112 and a second arc-shaped guide portion 4121 at their ends. The first arc-shaped guide portion 4112 slides along the second arc-shaped guide portion 4121 into the other end of the second limiting boss 412. This arc-shaped guide portion design facilitates the installation and disassembly of the positioning component and the bottom cover, reducing friction and jamming. In particular, both the first limiting boss 411 and the second limiting boss 412 are provided with several air chambers. The shape of the air chambers can be circular, elliptical, etc., and their function is to form a buffer at the connection point, reducing the impact of high-pressure water flow on the connection structure, and also reducing noise to a certain extent.
[0034] Continue to refer to Figure 2 and Figure 3 The outer wall of the positioning cylinder 1322 is also integrally formed with a first positioning ring 1324. The first positioning ring 1324 has a clearance opening at the position corresponding to the limiting groove 4111. When the top cover 11 and the bottom cover 12 are connected together, the two unlocking mechanisms 42 respectively engage with the corresponding limiting grooves 4111 along the corresponding clearance openings. This restricts the relative movement between the clamping mechanism 41 and the positioning cylinder 1322, further increasing the clamping firmness of the clamping mechanism 41.
[0035] Continue to refer to Figure 2 and Figure 3 In addition, the bottom cover 12 is equipped with two symmetrical unlocking mechanisms 42 for convenient unlocking and separation of the top cover 11 and the bottom cover 12 when needed. Each unlocking mechanism 42 includes a first rotating member 421 and a button 422. The first rotating member 421 is rotatably connected to the bottom cover 12, and the button 422 is slidably engaged with the bottom cover 12. The button 422 is used to drive the first rotating member 421 to rotate, thereby simultaneously unlocking the two clamping mechanisms 41.
[0036] Continue to refer to Figure 2 and Figure 3The first rotating component 421 includes a rotating shaft 4211, a driving block 4212, and a driven block 4213. One end of the driving block 4212 is integrally formed with the rotating shaft 4211, and one end of the driven block 4213 is integrally formed with the rotating shaft. The driving block 4212 and the driven block 4213 combine to form a V-shaped structure, and the driven block 4213 is movably engaged in the limiting groove 4111. Two mutually symmetrical supports 125 are integrally formed on the inner sidewall of the bottom cover 12. The rotating shaft 4211 passes through the supports 125 and is rotatably connected to the supports 125. Through sliding holes 126 are opened on opposite sides of the cover 122, corresponding one-to-one with the buttons 422. The buttons 422 pass through the sliding holes 126 and slide in engagement with the cover 122. The bottom end of the buttons 422 abuts against the end of the driving block 4212 away from the rotating shaft 4211. This allows the user to simply press button 422 to drive the driven block 4213 to move by rotating the first rotating component 421, thereby freeing the top cover 11 and bottom cover 12 from radial displacement restrictions, facilitating the rotation of the subsequent positioning cylinder 1322, and thus enabling manual replacement of the filter device 2.
[0037] Reference Figure 3 To prevent buttons 422 from accidentally falling off during use, an anti-detachment ring 4221 is integrally formed on the outer wall of each button 422 near the end of the first rotating member 421. The diameter of the anti-detachment ring 4221 is larger than the diameter of the button 422, providing additional support and fixation for the button 422, ensuring the stability and reliability of the button 422.
[0038] Reference Figure 7 The gear adjustment device 3 includes a drainage base 31, a mounting base 32, a gear adjustment mechanism 33, a reset mechanism 34, a buffer mechanism 35, and a diversion mechanism 36.
[0039] Continue to refer to Figure 6 The drainage base 31 includes a drainage chassis 311 and an annular member 312, the annular member 312 being integrally formed on the upper surface of the drainage chassis 311. The mounting seat 32 is fixed on the annular member 312, and a cavity 37 is formed between the mounting seat 32, the annular member 312 and the drainage base 31. The gear adjustment mechanism 33 is disposed on the mounting seat 32, with part of the gear adjustment mechanism located outside the cavity 37 and part of the gear adjustment mechanism 33 located inside the cavity 37.
[0040] Reference Figure 2 and Figure 7The gear adjustment mechanism 33 includes a drive rotating seat 331, an intermediate rotating seat 332, an annular rotating seat 333, and a gear adjustment seat 334. The drive rotating seat 331 is rotatably positioned between the diverting mechanism 36 and the mounting seat 32. The bottom of the diverting mechanism 36 abuts against the upper surface of the drive rotating seat 331, and the upper surface of the mounting seat 32 abuts against the lower surface of the drive rotating seat 331, increasing the stability of the drive rotating seat 331's rotation. The annular rotating seat 333 rotates intermittently with the mounting seat 32, rotating 20° each time. The intermediate rotating seat 332 is located between the drive rotating seat 331 and the annular rotating seat 333. The intermediate rotating seat 332 passes through the mounting seat 32 and is rotatably connected to it, rotating 20° each time. The intermediate rotating seat 332 and the annular rotating seat 333 are interlocked to ensure synchronous rotation. The active rotating seat 331 is rotatably connected to the intermediate rotating seat 332. During the rotation of the active rotating seat 331, the intermediate rotating seat 332 is driven to rotate intermittently. The intermediate rotating seat 332 is connected to the gear adjustment seat 334 by a plug-in engagement. During the rotation of the intermediate rotating seat 332, the gear adjustment seat 334 can be driven to rotate 20° each time.
[0041] Reference Figure 7 and Figure 8 The active rotating seat 331 has three slots 3311 circumferentially formed, and the inner wall of each slot 3311 is integrally formed with an inclined elastic driving part 3312. Each elastic driving part 3312 has a third inclined surface 3313 on the surface near the middle rotating seat 332, so that when the active rotating seat 331 and the middle rotating seat 332 rotate relative to each other, an effective driving force can be generated, thereby driving the middle rotating seat 332 to rotate intermittently, with each rotation being 20°.
[0042] Reference Figure 7 , Figure 8 and Figure 9The intermediate rotating seat 332 includes an integrally formed second rotating component 3321 and a first insert component 3322, ensuring the integrity and strength of the structure. The first insert component 3322 engages with the gear adjustment seat 334, which not only increases the ease of installation and disassembly of both, but also ensures that the intermediate rotating seat 332 and the gear adjustment seat 334 rotate synchronously. The upper surface of the second rotating component 3321 has nine centrally symmetrical driven ramps 3323 arranged circumferentially, and the upper surface of each driven ramp 3323 is provided with a guide arc surface 3324. The same end of each of the nine driven ramps 3323 is provided with a vertical positioning end face 3325. The third inclined surface 3313 of the elastic drive part 3312 abuts against the guide arc surface 3324 of the driven ramp 3323, and the end of the elastic drive part 3312 abuts against the positioning end face 3325 of the driven ramp 3323. When the active rotating seat 331 rotates clockwise, the third inclined surface 3313 and the guide arc surface 3324 rotate relative to each other. At this time, the active rotating seat 331 will not drive the intermediate rotating seat 332 to rotate. When the active rotating seat 331 rotates counterclockwise, the end of the elastic drive part 3312 abuts against the positioning end face 3325 of the driven inclined platform 3323. At this time, the active rotating seat 331 will drive the intermediate rotating seat 332 to rotate, and each rotation is 20°.
[0043] Reference Figure 7 , Figure 8 and Figure 9 The annular rotating seat 333 includes a rotating ring 3331, which is rotatably connected to the mounting base 32. Specifically, a first rotating groove 321 is formed on the upper surface of the mounting base 32. The depth of the first rotating groove 321 is less than the thickness of the mounting base 32, and the rotating ring 3331 is rotatably disposed inside the first rotating groove 321. In the middle of the first rotating groove 321, a first through hole 323 is also formed for the intermediate rotating seat 332 to pass through. The diameter of the first through hole 323 is smaller than the diameter of the first rotating groove 321. An annular shaft 322 is integrally formed at the bottom of the first rotating groove 321, and the rotating ring 3331 is sleeved on the annular shaft 322, and the rotating ring 3331 is rotatably connected to the annular shaft 322.
[0044] Continue to refer to Figure 7 , Figure 8 and Figure 9The rotating ring 3331 has multiple integrally formed insertion portions 3332 on the side facing the active rotating seat 331, while the active rotating seat 331 has multiple insertion slots circumferentially formed, each corresponding to one of the insertion portions 3332. These insertion portions 3332 and insertion slots engage with each other to ensure that the active rotating seat 331 can drive the annular rotating seat 333 to rotate synchronously, rotating 20° each time. Secondly, the outer wall of the rotating ring 3331 has three arc-shaped first stop members 3333 integrally formed. The first stop members 3333 have elastic deformation capabilities and can interact with nine driven ramps 3323 arranged circumferentially on the inner wall of the first rotating groove 321. These nine driven ramps 3323 are centrally symmetrically distributed, and each driven ramp 3323 includes a guide arc surface 3324 and a positioning end face 3325. This ensures that the intermediate rotating seat 332 can only rotate counterclockwise and not clockwise.
[0045] Continue to refer to Figure 7 , Figure 8 and Figure 9 Specifically, during the counterclockwise rotation of the intermediate rotating seat 332, the outer wall of the first stop 3333 abuts against the inner wall of the guide arc surface 3324, allowing it to rotate smoothly along the guide arc surface 3324, rotating 20° each time. When attempting to rotate the intermediate rotating seat 332 clockwise, the positioning end face 3325 of the driven inclined platform 3323 blocks the end of the first stop 3333, thus preventing clockwise rotation. This not only ensures smooth rotation but also provides effective restriction on the direction of rotation.
[0046] Continue to refer to Figure 7 , Figure 8 and Figure 9 When the active rotating seat 331 and the intermediate rotating seat 332 rotate relative to each other, the third inclined surface 3313 of the elastic drive unit 3312 abuts against the guide arc surfaces 3324 of the three driven inclined platforms 3323. This abutting relationship allows them to generate an interaction force during rotation. Specifically, when the active rotating seat 331 rotates clockwise, the interaction force between the elastic drive unit 3312 and the driven inclined platforms 3323 is insufficient to overcome other resistances, so the active rotating seat 331 will not drive the intermediate rotating seat 332 to rotate. However, when the active rotating seat 331 rotates counterclockwise, the end of the elastic drive unit 3312 pushes the positioning end face 3325 of the driven inclined platform 3323, thereby generating sufficient driving force to drive the intermediate rotating seat 332 to rotate. This not only restricts the direction of rotation but also ensures the reliability and accuracy of the rotation operation.
[0047] Reference Figure 7 and Figure 8The reset mechanism 34 includes a drive seat 341 and a second elastic element 342. One end of the drive seat 341 is fixedly connected to the active rotating seat 331. The side wall of the base cover 12 has a sliding hole 126 through which the drive seat 341 passes. The sliding hole 126 extends horizontally, and the drive seat 341 slides and engages with the sliding hole 126 during rotation. One end of the second elastic element 342 is connected to the drive seat 341, and the other end is connected to the drain base 31. In this embodiment, the second elastic element 342 is specifically a spring. When the drive seat 341 rotates from one end of the sliding hole 126 to the other end, the active rotating seat 331 rotates exactly 20°, realizing one gear adjustment. When an external force is applied to the drive seat 341, the drive seat 341 returns to its initial position under the elastic force of the second elastic element 342, thus facilitating the next gear adjustment.
[0048] Reference Figure 9 The gear adjustment seat 334 includes a second connector 3341 and a gear adjustment disc 3342. The bottom end of the second connector 3341 is integrally formed with the upper surface of the gear adjustment disc 3342. The second connector 3341 is inserted into and cooperates with the first connector 3322, thereby connecting the gear adjustment seat 334 and the intermediate rotating seat 332 together, thus ensuring that the intermediate rotating seat 332 can rotate with the gear adjustment seat 334 when rotating, thereby realizing the adjustment of the water outlet pattern.
[0049] Reference Figure 9 and Figure 10The gear adjustment plate 3342 has three second water inlets 3343 along its circumference, and the three first water outlets 124 are evenly distributed along the circumference to ensure that the angle between the line connecting two adjacent second water inlets 3343 and the center of the gear adjustment plate 3342 is exactly 60°. The drainage base 31 has four drainage holes arranged equidistantly along its circumferential direction: a first drainage hole 3111, a second drainage hole 3112, a third drainage hole 3113, and a fourth drainage hole 3114. The center of the arc of the four drainage holes is defined as the center point. The line connecting the center of the first drainage hole and the center point is defined as the first line segment, the line connecting the center of the second drainage hole and the center point is defined as the second line segment, the line connecting the center of the third drainage hole and the center point is defined as the third line segment, and the line connecting the center of the fourth drainage hole and the center point is defined as the fourth line segment. The included angle between the first and second line segments is 20°, the included angle between the second and third line segments is 20°, the included angle between the third and fourth line segments is 20°, and the included angle between the first and third line segments is 60°. Because the three second water inlets 3343 and the three first water outlets 124 are evenly distributed at equal intervals along the circumference, and the included angle between the first line segment and the third line segment is specially set to 60°, which matches the arrangement angle of the second water inlets 3343, it ensures that the gear adjustment plate 3342 can achieve three different water outlet gears when it rotates, thus ensuring that the gear adjustment plate 3342 can achieve three different water outlet gears during rotation.
[0050] Reference Figure 9 , Figure 10 and Figure 11Meanwhile, the lower surface of the drainage base 311 is provided with a first isolation ring 3115, a second isolation ring 3116, a third isolation ring 3117, and a sealing ring 3118, with gradually increasing diameters, arranged from the inside to the outside. The outer wall of the sealing ring 3118 is also provided. The first drainage hole 3111 and the second drainage hole 3112 are located between the first isolation ring 3115 and the second isolation ring 3116; the third drainage hole 3113 is located between the second isolation ring 3116 and the third isolation ring 3117; and the fourth drainage hole 3114 is located between the third isolation ring 3117 and the sealing ring 3118. When one of the second water inlets 3343 is aligned with the first drain hole 3111, the adjacent second water inlet 3343 is aligned with the fourth drain hole 3114, achieving the maximum water output. When one of the second water inlets 3343 is aligned with either the second drain hole 3112 or the third drain hole 3113, the other two second water inlets 3343 are blocked by the drain base 31. Users can easily adjust the water output pattern according to their actual needs, achieving three different water output effects: spray, rain, and jet. Furthermore, it is worth noting that the diameters of the first drain hole 3111, second drain hole 3112, third drain hole 3113, and fourth drain hole 3114 can be flexibly designed according to actual needs; they can be the same or different to meet the personalized needs of different users.
[0051] Reference Figure 10 In order to increase the stability of the rotation of the gear adjustment disc 3342, the upper surface of the drain base 31 is also provided with multiple positioning protrusions 313. The multiple positioning protrusions 313 are arranged circumferentially, and four positioning protrusions 313 correspond to four drain holes one by one.
[0052] Reference Figure 7 and Figure 10 The buffer mechanism 35 is located between the gear shift adjustment disc 3342 and multiple positioning protrusions 313. The buffer mechanism 35 includes an annular flexible buffer pad 351, on which multiple circumferentially arranged second through holes 3511 are formed. Each second through hole 3511 corresponds to a positioning protrusion 313, and each positioning protrusion 313 passes through a second through hole 3511. At the same time, the flexible buffer pad 351 covers the outer side wall of the multiple positioning protrusions 313. The flexible buffer pad 351 protects both the gear shift adjustment disc 3342 and the drainage base 31, extending their service life.
[0053] Reference Figure 7 , Figure 8 and Figure 10The buffer mechanism 35 also includes a first concave-convex seat 352 and a second concave-convex seat 353. The first concave-convex seat 352 is integrally formed on the upper surface of the drainage base 311, and the second concave-convex seat 353 is integrally formed on the lower surface of the gear adjustment disc 3342. The top of the first concave-convex seat 352 has a second rotating groove 3521. The bottom of the second rotating groove 3521 is provided with a plurality of first protrusions 3522 along the circumferential direction, and a first groove 3523 is formed between two adjacent protrusions. The structure of the first protrusion 3522 and the groove is triangular. The second concave-convex seat 353 is rotatably connected to the second rotating groove 3521. The end shape of the second concave-convex seat 353 is completely matched with the structure of the top of the first concave-convex seat 352. This allows the gear adjustment disc 3342 to be smoothly rotatably connected to the drainage base 31, which not only ensures the smooth rotation of the gear adjustment disc 3342, but more importantly, it plays a good protective role for the soft buffer pad, avoiding wear or damage caused by long-term or frequent contact.
[0054] Reference Figure 5 and Figure 7 The diversion mechanism 36 includes a diversion seat 361. Multiple bolt posts are integrally formed on the inner wall of the base cover 12, and the surfaces of these bolt posts abut against the surface of the diversion seat 361, thereby fixing the diversion seat 361 inside the base cover 12. In this embodiment, the diversion seat 361 is located between the filter device 2 and the gear adjustment mechanism 33. A positioning groove 362 is formed at the center of the top of the diversion seat 361. A third positioning ring 232 is integrally formed on the lower surface of the second sleeve 23. The outer wall of the third positioning ring 232 abuts against the inner wall of the positioning groove 362, thereby fixing the second sleeve 23 onto the diversion seat 361. Simultaneously, a sealing ring is provided between the outer wall of the third positioning ring 232 and the inner wall of the positioning groove 362, increasing the sealing performance between them.
[0055] Reference Figure 2 , Figure 5 and Figure 7 The second sleeve 23, the third positioning ring 232, and the diverter seat 361 enclose a water storage cavity 363. The bottom of the positioning groove 362 has a through-hole 364 and a second diverter hole 365, which are independent of each other and not connected. The first diverter hole 364 directly directs the clean water in the water storage cavity 363 to the speed adjustment device 3. After precise speed control, the water flow elegantly sprinkles onto the water outlet panel 123, providing the user with a delicate and varied water flow experience.
[0056] Reference Figure 2 and Figure 7In this embodiment, the second diversion hole 365 passes sequentially through the diversion mechanism 36, the mounting base 32, and the drainage chassis 311. A fragrance release device 5 is embedded within the second diversion hole 365. Inspired by a push-button cylindrical pen, this mechanism is not only easy to operate but also multifunctional. It can flexibly store various items such as flavoring agents, aromatherapy tablets, and soap, adding a unique touch to the water flow. When the user wishes to replace these flavoring items, a simple press is all it takes to easily install and remove the fragrance release device 5, thus allowing for convenient and quick replacement of the items within it.
[0057] It is worth mentioning that the second diversion hole 365, acting as a bridge connecting the water storage chamber 363 and the fragrance release device 5, ensures that water flows smoothly through the fragrance release device 5, fully absorbing the fragrance or scent therein, and then acting on the user through the water outlet panel 123. The implementation principle of this embodiment is as follows: This embodiment, through a simplified connection structure and ingenious design, makes filter replacement more convenient and quick. The cooperation of the clamping mechanism and unlocking mechanism of the clamping device allows for quick connection and disassembly of the positioning component and the base cover, reducing operation steps and time. Simultaneously, the cooperation of the first limiting boss 411 and the second limiting boss 412, along with the setting of the air chamber, improves the stability of the connection structure, enhances the shower head's resistance to high-pressure water flow, and is more reliable and durable than traditional connection methods, improving the user experience.
[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
