In addition, they lack an efficient gear adjustment mechanism and cannot flexibly adjust the water flow rate and spraying mode, making it difficult to meet the diverse needs of users. Summary of the invention

[0005] In order to overcome the defects of the prior art and enhance the user's shower experience, the present application provides a top spray shower.

[0006] The present application provides a top spray shower head adopting the following technical solution: A top spray showerhead comprises a shell device, a filter device and a gear adjustment device, wherein the shell device comprises a detachably connected top cover and a bottom cover, a water inlet is provided at the end of the top cover, and a first water outlet is provided at the end of the bottom cover; the filter device is arranged inside the top cover for intercepting impurities and particulate matter in the water; the gear adjustment device is located inside the bottom cover for adjusting the water flow rate and the spraying mode, a drainage channel for connecting the filter device and the gear adjustment device is provided in the shell device, one end of the drainage channel is connected to the water inlet, and the other end of the drainage channel is connected to the first water outlet.

[0007] By adopting the above technical solution, this top spray shower achieves the purification of shower water quality and the flexible adjustment of water flow and spray mode through its carefully designed shell device (including detachable top cover and bottom cover), built-in filtering device and gear adjustment device. Water enters from the water inlet at the end of the top cover, intercepts impurities through the filtering device, and flows into the gear adjustment device in the bottom cover through the drainage channel. Users can adjust the gear to change the water flow and spray mode according to their needs. Finally, clean and personalized water flows out from the first water outlet at the end of the bottom cover, which not only ensures the cleanliness of the shower water quality, but also improves the personalization and comfort of the shower experience.

[0008] Optionally, the gear adjustment device includes a drainage base, a mounting seat, a gear adjustment mechanism and a reset mechanism, the drainage base is arranged in the bottom cover, the mounting seat is arranged on the drainage base, and the gear adjustment mechanism is arranged on the mounting seat for adjusting the water outlet form; one end of the reset mechanism is connected to the gear adjustment mechanism, and the other end of the reset mechanism is connected to the bottom cover.

[0009] By adopting the above technical solution, the gear adjustment device includes a drainage base, a mounting seat, a gear adjustment mechanism and a reset mechanism, which work together to achieve precise control of the water flow. After being filtered, the water flows into the drainage base, and then the gear adjustment mechanism adjusts the water output form according to user needs, such as changing the water flow intensity, spraying range, etc. The reset mechanism ensures that the gear adjustment mechanism can automatically return to the preset state when it is not affected by external forces, which is convenient for the next use. This design not only improves the comfort and personalization of the shower, but also ensures the accuracy and stability of the adjustment through structural optimization, bringing users a better shower experience.

[0010] Optionally, the gear adjustment mechanism includes an active rotating seat, an intermediate rotating seat, an annular rotating seat and a gear adjustment seat; the active rotating seat is rotatably arranged in the bottom cover; the intermediate rotating seat is penetrated by the mounting seat and is rotatably connected to the mounting seat, the annular rotating seat is rotatably connected to the mounting seat, and the intermediate rotating seat is plug-fitted with the annular rotating seat to ensure synchronous rotation of the two; the active rotating seat is rotatably connected to the intermediate rotating seat, and the active rotating seat drives the intermediate rotating seat to rotate intermittently when rotating; the gear adjustment seat is plug-fitted with the intermediate rotating seat, and the intermediate rotating seat drives the gear adjustment seat to rotate a preset angle each time during the rotation process.

[0011] By adopting the above technical solution, the active rotating seat rotates flexibly in the bottom cover, and drives the intermediate rotating seat to rotate intermittently through its unique transmission method. At the same time, the plug-in cooperation between the intermediate rotating seat and the annular rotating seat ensures the synchronous rotation of the two, enhancing the stability and durability of the structure. During the rotation process, the intermediate rotating seat drives the gear adjustment seat to rotate a preset angle each time through plug-in cooperation, thereby achieving precise adjustment of the water outlet shape. This design not only enhances the personalized shower experience, but also ensures the accuracy and smoothness of the adjustment through structural optimization, bringing users a more delicate and rich shower experience.

[0012] Optionally, three second water inlet holes are provided on the gear adjustment seat along the circumference, and three first water outlet holes are evenly distributed along the circumference; the first drainage hole, the second drainage hole, the third drainage hole and the fourth drainage hole are evenly arranged along the circumference on the drainage base, wherein the angles formed by the four drainage holes relative to the center point of the drainage base are set as follows: the angle between the line connecting the first drainage hole and the center point and the line connecting the second drainage hole and the center point is 20°, the angle between the second line segment and the line connecting the third drainage hole and the center point is also 20°, and the angle between the third line segment and the line connecting the fourth drainage hole and the center point is also 20°, so that the gear adjustment dial can accurately switch to three different water outlet gears during rotation.

[0013] By adopting the above technical solution, the precise switching of water outlet gears and diversified water outlet modes are achieved through its innovative gear adjustment seat and drainage base design. The three evenly distributed second water inlet holes on the gear adjustment seat cooperate with the four drainage holes arranged at a specific angle (the angle between every two adjacent drainage holes is 20°) on the drainage base. When the gear adjustment seat rotates with the middle rotating seat, it can accurately switch to three different water outlet gears. Each gear corresponds to a different combination of drainage holes, thereby bringing different water flow intensity, spraying range and form. This design not only significantly improves the personalization and comfort of the shower, but also ensures the stability of the water outlet mode and the accuracy of switching through fine adjustment of the structure, providing users with a richer and more delicate shower experience.

[0014] Optionally, a plurality of circumferentially arranged positioning protrusions are provided on the upper surface of the drain base, the positioning protrusions are used to position the water inlet hole on the gear adjustment seat, a buffer mechanism is provided between the gear adjustment seat and the drain base, the buffer mechanism includes a flexible buffer pad, the flexible buffer pad has a plurality of second through holes circumferentially corresponding to the positioning protrusions, the positioning protrusion is penetrated in the second through hole, and the flexible buffer pad is covered on the outside of the positioning protrusion.

[0015] By adopting the above technical solution, the stability and durability of the water outlet gear switching are further improved by adding a buffer mechanism between the positioning convex ring on the drainage base and the gear adjustment seat. The positioning convex ring accurately locates the water inlet hole on the gear adjustment seat to ensure that it can accurately correspond to different drainage hole combinations after each rotation, thereby achieving stable switching of the water outlet mode. The flexible buffer pad in the buffer mechanism can not only effectively reduce the friction and wear of the gear adjustment seat during rotation and extend its service life, but also provide a certain degree of buffering through its elastic characteristics, making the switching of the water outlet mode smoother and smoother. This design not only enhances the comfort of the shower experience, but also improves the reliability and durability of the entire overhead shower head through structural optimization.

[0016] Optionally, the buffer mechanism also includes a first concave-convex seat and a second concave-convex seat, wherein the first concave-convex seat is fixed to the upper surface of the drainage base plate of the drainage base, and the second concave-convex seat is fixed to the gear adjustment dial; a second rotation groove is designed at the top of the first concave-convex seat, and a plurality of first protrusions are arranged circumferentially at the bottom of the groove, and a triangular first groove is formed between adjacent protrusions; the second concave-convex seat is rotatably matched with the second rotation groove, and the shape of the end of the second concave-convex seat matches the top structure of the first concave-convex seat.

[0017] By adopting the above technical solution, the second rotating groove at the top of the first concave-convex seat and the first protrusion and first groove structure inside it match the shape of the end of the second concave-convex seat, ensuring the precise alignment and stable operation of the gear adjustment disk during the rotation process, and reducing the noise and wear caused by poor rotation; the close fit between the first concave-convex seat and the second concave-convex seat effectively disperses the friction generated during rotation and reduces the direct contact area between the two, thereby reducing the wear problems that may occur during long-term use and extending the service life of the product; by optimizing the design of the rotating mechanism, the user can feel better and operate more smoothly when adjusting the water outlet gear, thereby improving the overall user experience.

[0018] Optionally, the reset mechanism includes a driving seat and a second elastic member; one end of the driving seat is fixedly connected to the active rotating seat, and the side wall of the bottom cover is provided with a sliding hole for the driving seat to pass through, and the sliding hole extends in a horizontal direction. The driving seat passes through the sliding hole, and the driving seat slides with the sliding hole during rotation; one end of the second elastic member is connected to the driving seat, and the other end of the second elastic member is connected to the drainage base; after the external force disappears, the driving seat rotates to an initial position under the elastic force of the second elastic member.

[0019] By adopting the above technical solution and its ingenious reset mechanism design, the automatic reset function of the gear adjustment is realized. The reset mechanism consists of a drive seat and a second elastic member. The drive seat is fixedly connected to the active rotating seat and can slide and rotate horizontally along the sliding hole on the side wall of the bottom cover. Under the action of external force, the drive seat drives the active rotating seat and the entire gear adjustment mechanism to rotate to the required water outlet gear; when the external force disappears, the second elastic member uses its elastic force to push the drive seat and the active rotating seat to automatically rotate back to the initial position, thereby realizing automatic reset of the gear. This design not only simplifies user operation and improves the convenience of the shower experience, but also ensures the accuracy and stability of the gear adjustment through structural optimization, providing users with a more worry-free and comfortable shower experience.

[0020] Optionally, it also includes a clamping device, which includes at least one clamping mechanism and at least one unlocking mechanism. The clamping mechanism is arranged on the bottom cover, and the clamping mechanism is used to clamp and fix the top cover; the unlocking mechanism is arranged on the bottom cover, and the unlocking mechanism is used to unlock the clamping mechanism.

[0021] By adopting the above technical solution, the clamping device can realize the rapid assembly and disassembly of the top cover and the bottom cover. The clamping mechanism uses the elastic force provided by the first elastic member to make the clamping half ring close to the top cover, ensuring the stable connection between the top cover and the bottom cover. The unlocking mechanism drives the first rotating member to rotate through the button, thereby driving the linkage block to move, releasing the locking state of the clamping half ring, making it convenient for users to easily separate the top cover and the bottom cover when needed, and facilitating the cleaning and maintenance of internal components.

[0022] Optionally, the clamping mechanism includes a clamping half ring and a first elastic member, and the clamping half ring is arranged between the carrying ring and the gear adjustment device; one end of the first elastic member abuts against the outer wall of the clamping half ring, and the other end of the first elastic member abuts against the inner wall of the bottom cover, and the clamping half ring generates an elastic force toward the direction close to the clamping half ring under the elastic force of the first elastic member.

[0023] By adopting the above technical solution, the clamping mechanism can effectively fix the top cover and the bottom cover to ensure the structural stability and sealing of the top spray shower. The clamping half ring is tightly attached to the top cover under the elastic force of the first elastic member to prevent water leakage, and it is also convenient for users to quickly disassemble and assemble the top cover for cleaning and maintenance.

[0024] Optionally, the unlocking mechanism includes a first rotating member and a button, the first rotating member is rotatably connected to the bottom cover, one end of the first rotating member is located on the inner wall of the end of the clamping semi-ring; the button is slidably matched with the bottom cover to drive the other end of the first rotating member to rotate.

[0025] By adopting the above technical solution, the setting of the unlocking mechanism allows the user to unlock the clamping mechanism by simply operating the button, thereby conveniently separating the top cover and the bottom cover, and facilitating the cleaning and replacement of the filter device. The first rotating member is rotatably connected to the bottom cover, and one end of the first rotating member is located on the inner side wall of the end of the clamping semi-ring. When the user presses the button, the button drives the first rotating member to rotate, thereby driving the clamping semi-ring to loosen, so that the connection between the top cover and the bottom cover is released. This design not only improves the user experience, but also simplifies the maintenance process, and enhances the practicality and convenience of the product.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The filter device is installed inside the top cover, which can effectively intercept impurities and particles in the water, ensure the cleanliness and hygiene of the water, and protect the user's skin health; 2. The gear adjustment device can accurately switch to three different water outlet gears through the coordinated action of the active rotating seat, the intermediate rotating seat, the annular rotating seat and the gear adjustment seat, realizing multiple spraying modes such as spray, rain, and laser to meet the different needs of users; 3. The reset mechanism, through the action of the driving seat and the second elastic member, can automatically rotate to the initial position after the external force disappears, thereby ensuring the stability and reliability of the gear adjustment process.

The first clamping member 134 and the second clamping member 135 are both annular, and an arc groove is provided on the side of the first clamping member 134 and the second clamping member 135 close to the ball head seat 1333, 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. At the same time, the inner side wall is integrally formed with a 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 .

[0048] Reference Figure 2 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. The first sleeve 22 and the second sleeve 23 are both fixed to the filter element 21. The first sleeve 22 is fixed to the inner wall of the connecting ring 1323, so that the filter device 2 can be installed in the top cover 11.

[0049] Reference Figure 4 and Figure 5 The outer side wall of the first sleeve 22 is integrally formed with a plurality of annular first flanges 221, and the plurality of first flanges 221 are arranged at intervals along the length direction of the axis. At the same time, the inner side walls of the positioning cylinder 1322 and the connecting ring 1323 are circumferentially provided with a plurality of L-shaped second flanges 231, and the plurality of second flanges 231 are arranged circumferentially.

A clamping device 4 for clamping and fixing the top cover 11 is provided in the bottom cover 12, which increases the convenience for the staff to install and remove the top cover 11, thereby increasing the convenience for the staff to replace the filter device 2.

[0051] Continue to refer to Figure 2 and Figure 3 The clamping device 4 includes two clamping mechanisms 41 and two unlocking mechanisms 42, and the two clamping mechanisms 41 are symmetrical to each other. Each clamping mechanism 41 includes a clamping half ring 411 and a first elastic member 412. The clamping half ring 411 is cleverly arranged between the load-bearing ring 121 and the gear adjustment device 3, and plays a key connecting role. The specific first elastic member 412 is a spring, which is arranged between the clamping half ring 411 and the cover body 122. One end of the first elastic member 412 abuts against the outer wall of the clamping half ring 411, and the other end of the first elastic member 412 abuts firmly against the inner wall of the cover body 122. Under the elastic force of the first elastic member 412, the two clamping half rings 411 can move toward the direction of approaching each other, thereby clamping the positioning cylinder 1322, thereby realizing a stable connection between the top cover 11 and the bottom cover 12.

[0052] 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. When the top cover 11 and the bottom cover 12 are connected together, the lower surfaces of the two clamping half rings 411 will tightly abut against the upper surface of the first positioning ring 1324 under the elastic force of the spring. This prevents the clamping mechanism 41 and the positioning cylinder 1322 from moving relative to each other, and further increases the firmness of the clamping mechanism 41 clamping the clamping mechanism 41.

[0053] Continue to refer to Figure 2 and Figure 3 In addition, the bottom cover 12 is also equipped with two mutually symmetrical unlocking mechanisms 42 for conveniently unlocking and separating 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 matched 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.

[0054] Continue to refer to Figure 2 and Figure 3The first rotating member 421 includes a rotating shaft 4211, an active block 4212, a driven block 4213 and a linkage block 4214. One end of the active 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 active block 4212 and the driven block 4213 are combined to form a V-shaped structure, and the linkage block 4214 is integrally formed at one end of the driven block 4213 away from the rotating shaft 4211. Two mutually symmetrical supports 125 are integrally formed on the inner side wall of the bottom cover 12. The rotating shaft 4211 is penetrated through the supports 125 and is rotatably connected to the supports 125. The linkage block 4214 is located between the two clamping half rings 411 and abuts against the inner side walls of the two clamping half rings 411 at the same time. The cover body 122 has two opposite sides provided with penetrating sliding holes 126, which correspond to the buttons 422 one by one. The button 422 passes through the sliding hole 126 and slides with the cover body 122, and the bottom end of the button 422 abuts against the end of the active block 4212 away from the rotating shaft 4211. The user only needs to press the button 422 lightly to drive the linkage block 4214 to move through the rotation of the first rotating member 421, thereby easily unlocking the clamping half ring 411 and separating the top cover 11 and the bottom cover 12, so as to facilitate the separation of the top cover 11 and the bottom cover 12 from each other, thereby realizing manual replacement of the filter device 2.

[0055] Continue to refer to Figure 2 and Figure 3 , the outer side wall of the end of each linkage block 4214 is provided with a first inclined surface 4215, and at the same time, the inner side wall of the end of each clamping half ring 411 is provided with a second inclined surface 413. The first inclined surface 4215 and the corresponding second inclined surface 413 are in contact and fit with each other. The two symmetrically arranged unlocking mechanisms 42 cooperate with the button 422 through the first rotating member 421. The rotating shaft 4211 is rotatably connected to the symmetrical support 125 on the inner side of the bottom cover 12. The active block 4212 and the driven block 4213 of the V-shaped structure enable the linkage block 4214 to move with the rotation of the first rotating member 421 and be inserted into the gap between the two clamping half rings 411. The first inclined surface 4215 at the end of the linkage block 4214 and the second inclined surface 413 of the inner side wall of the clamping half ring 411 are in contact with each other to achieve stable abutment. When the user presses the button 422 , the button 422 slides along the sliding hole 126 of the cover body 122 and pushes the active block 4212 , thereby driving the entire first rotating member 421 and the linkage block 4214 to move, and finally realizing the unlocking function.

[0056] Reference Figure 2 In order to prevent the button 422 from accidentally falling off during use, an outer wall 4221 is integrally formed on one end of each button 422 close to the first rotating member 421. The diameter of 4221 is larger than the diameter of the button 422, providing additional support and fixing for the button 422, ensuring the stability and reliability of the button 422.

[0057] Reference Figure 6 The gear adjustment device 3 includes a drainage base 31 , a mounting seat 32 , a gear adjustment mechanism 33 , a reset mechanism 34 , a buffer mechanism 35 and a diversion mechanism 36 .

[0058] Continue to refer to Figure 6 The drain base 31 includes a drain bottom plate 311 and an annular member 312, and the annular member 312 is integrally formed on the upper surface of the drain bottom plate 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 drain base 31. The gear adjustment mechanism 33 is arranged on the mounting seat 32, and part of the gear adjustment mechanism 33 is located outside the cavity 37, and part of the gear adjustment mechanism 33 is located inside the cavity 37.

[0059] Reference Figure 2 and Figure 6 The gear adjustment mechanism 33 includes an active rotating seat 331, an intermediate rotating seat 332, an annular rotating seat 333 and a gear adjustment seat 334. The active rotating seat 331 is rotatably arranged between the diverter mechanism 36 and the mounting seat 32, the bottom of the diverter mechanism 36 abuts against the upper surface of the active rotating seat 331, and the upper surface of the mounting seat 32 abuts against the lower surface of the active rotating seat 331, thereby increasing the stability of the rotation of the active rotating seat 331. The annular rotating seat 333 and the mounting seat 32 rotate intermittently, each time rotating 20°. The intermediate rotating seat 332 is located between the active rotating seat 331 and the annular rotating seat 333, the intermediate rotating seat 332 is penetrated through the mounting seat 32 and is rotatably connected with the mounting seat 32, each time rotating 20°, the intermediate rotating seat 332 and the annular rotating seat 333 are plugged and matched, thereby ensuring that the two rotate synchronously. The active rotating seat 331 is rotatably connected to the intermediate rotating seat 332. The active rotating seat 331 drives the intermediate rotating seat 332 to rotate intermittently during the rotation process. The intermediate rotating seat 332 is connected to the gear adjustment seat 334 by plug-in cooperation. The intermediate rotating seat 332 can drive the gear adjustment seat 334 to rotate 20° each time during the rotation process.

[0060] Reference Figure 6 and Figure 7 The active rotating seat 331 is provided with three slots 3311 along the circumferential direction, and the inner side wall of each slot 3311 is integrally formed with an inclined elastic driving part 3312. A third inclined surface 3313 is provided on the surface of each elastic driving part 3312 close to the intermediate rotating seat 332, so that when the active rotating seat 331 and the intermediate rotating seat 332 rotate relative to each other, an effective driving force can be generated, thereby driving the intermediate rotating seat 332 to rotate intermittently, each time by 20°.

[0061] Reference Figure 6 , Figure 7 and Figure 8 , the intermediate rotating seat 332 includes an integrally formed second rotating member 3321 and a first plug-in member 3322, which ensures the integrity and strength of the structure. The first plug-in member 3322 is plugged into the gear adjustment seat 334, which not only increases the convenience of installation and disassembly of the two, but also ensures that the intermediate rotating seat 332 and the gear adjustment seat 334 rotate synchronously. Nine driven ramps 3323 are arranged along the circumferential direction on the upper surface of the second rotating member 3321, and a guide arc surface 3324 is provided on the upper surface of each driven ramp 3323. A vertical positioning end surface 3325 is arranged at the same end of the nine driven ramps 3323. The third inclined surface 3313 of the elastic driving part 3312 abuts against the guide arc surface 3324 of the driven ramp 3323, and the end of the elastic driving part 3312 abuts against the positioning end surface 3325 of the driven ramp 3323. When the active rotating seat 331 rotates clockwise, the third inclined surface 3313 and the guiding arc surface 3324 rotate relative to each other, and the active rotating seat 331 does not drive the intermediate rotating seat 332 to rotate. When the active rotating seat 331 rotates counterclockwise, the end of the elastic driving part 3312 abuts against the positioning end surface 3325 of the driven inclined platform 3323, and the active rotating seat 331 drives the intermediate rotating seat 332 to rotate, and each time it rotates 20°.

[0062] Reference Figure 6 , Figure 7 and Figure 8 The annular rotating seat 333 includes a rotating ring 3331, and the rotating ring 3331 is rotatably connected to the mounting seat 32. Specifically, a first rotating groove 321 is provided on the upper surface of the mounting seat 32, the depth of the first rotating groove 321 is less than the thickness of the mounting seat 32, and the rotating ring 3331 is rotatably arranged inside the first rotating groove 321. In the middle of the first rotating groove 321, a first through hole 323 is also provided for the middle rotating seat 332 to pass through, and the diameter of the first through hole 323 is less 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.

[0063] Continue to refer to Figure 6 , Figure 7 and Figure 8, a plurality of plug-in parts 3332 are integrally formed on the side of the rotating ring 3331 facing the active rotating seat 331, and a plurality of plug-in slots corresponding to the plug-in parts 3332 are provided on the active rotating seat 331 along the circumferential direction. These plug-in parts 3332 and the plug-in slots are plugged in and matched to ensure that the active rotating seat 331 can drive the annular rotating seat 333 to rotate synchronously when rotating, and rotate 20° each time. Secondly, three arc-shaped first stoppers 3333 are integrally formed on the outer wall of the rotating ring 3331. The first stopper 3333 has the ability of elastic deformation and can interact with the nine driven ramps 3323 arranged along the circumferential direction on the inner side 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 surface 3325. It is ensured that the intermediate rotating seat 332 can only rotate counterclockwise, but not clockwise.

[0064] Continue to refer to Figure 6 , Figure 7 and Figure 8 Specifically, during the counterclockwise rotation of the intermediate rotating seat 332, the outer wall of the first stopper 3333 abuts against the inner wall of the guide arc surface 3324, and smoothly rotates along the guide arc surface 3324, rotating 20° each time. When the intermediate rotating seat 332 is attempted to rotate clockwise, the positioning end surface 3325 of the driven ramp 3323 blocks the end of the first stopper 3333, thereby preventing the clockwise rotation from occurring. This not only ensures the smoothness of the rotation, but also provides effective rotation direction restriction.

[0065] Continue to refer to Figure 6 , Figure 7 and Figure 8 , 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 driving part 3312 will respectively abut against the guide arc surface 3324 of three of the driven inclined platforms 3323. This abutting relationship enables the two to generate an interaction force during the rotation process. In particular, when the active rotating seat 331 rotates clockwise, since the direction of the interaction force between the elastic driving part 3312 and the driven inclined platform 3323 is not sufficient to overcome other resistances, 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 driving part 3312 will push the positioning end surface 3325 of the driven inclined platform 3323, thereby generating sufficient driving force to drive the intermediate rotating seat 332 to rotate. Not only is the restriction of the rotation direction achieved, but also the reliability and accuracy of the rotation action are ensured.

[0066] Reference Figure 6 and Figure 7The reset mechanism 34 includes a drive seat 341 and a second elastic member 342. One end of the drive seat 341 is fixedly connected to the active rotating seat 331. The side wall of the bottom cover 12 is provided with a sliding hole 126 for the drive seat 341 to pass through. The sliding hole 126 extends in the horizontal direction. The drive seat 341 slides and cooperates with the sliding hole 126 when rotating. One end of the second elastic member 342 is connected to the drive seat 341, and the other end of the second elastic member 342 is connected to the drainage base 31. In this embodiment, the specific second elastic member 342 is a spring. When the drive seat 341 rotates from one end of the sliding hole 126 to the other end of the sliding hole 126, the active rotating seat 331 just rotates 20° to achieve a gear adjustment. When the external force on the drive seat 341 is applied, the drive seat 341 rotates back to the initial position under the elastic force of the second elastic member 342, so as to facilitate the next gear adjustment.

[0067] Reference Figure 8 The gear adjustment seat 334 includes a second connector 3341 and a gear adjustment disk 3342, and the bottom end of the second connector 3341 is integrally formed with the upper surface of the gear adjustment disk 3342. The second connector 3341 is plugged and matched with the first connector 3322, so as to connect the gear adjustment seat 334 with the middle rotating seat 332, so as to ensure that the middle rotating seat 332 can rotate with the gear adjustment seat 334 when rotating, so as to adjust the water outlet shape.

[0068] Reference Figure 8 and Fig. 9Three second water inlet holes 3343 are opened on the gear adjustment disk 3342 along the circumference, and the three first water outlet holes 124 are evenly distributed along the circumference with equal intervals to ensure that the angle between the line connecting two adjacent second water inlet holes 3343 and the center of the gear adjustment disk 3342 is exactly 60°. A first drainage hole 3111, a second drainage hole 3112, a third drainage hole 3113 and a fourth drainage hole 3114 are equidistantly arranged in sequence along the circumferential direction on the drainage base 31. The center of the arc where the four drainage holes are located 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, the line connecting the center of the fourth drainage hole and the center point is defined as the fourth line segment, the angle between the first line segment and the second line segment is 20°, the angle between the second line segment and the third line segment is 20°, the angle between the third line segment and the fourth line segment is 20°, and the angle between the first line segment and the third line segment is 60°. Since the three second water inlet holes 3343 and the three first water outlet holes 124 are evenly distributed along the circumferential direction at equal intervals, and the 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 inlet holes 3343, it is ensured that three different water outlet gears can be achieved when the gear adjustment disk 3342 rotates, thereby ensuring that the gear adjustment disk 3342 can achieve three different gears of water outlet during the rotation process.

[0069] Reference Figure 8 and Fig. 9At the same time, the lower surface of the drainage chassis 311 is provided with a first isolation ring 3115, a second isolation ring 3116, a third isolation ring 3117 and a sealing ring 3118, and the outer side wall of the sealing ring 3118, which have gradually increasing diameters, from the inside to the outside. 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 inlet holes 3343 is aligned with the first drainage hole 3111, the adjacent second water inlet hole 3343 is aligned with the fourth drainage hole 3114, and the maximum water output is achieved. When one of the second water inlet holes 3343 is aligned with the second drainage hole 3112 or the third drainage hole 3113, the other two second water inlet holes 3343 will be blocked by the drainage base 31. The user can easily adjust the water output form according to actual needs to achieve three different water output effects such as spray, rain, and laser. In addition, it is worth noting that the diameters of the first drainage hole 3111, the second drainage hole 3112, the third drainage hole 3113, and the fourth drainage hole 3114 can be flexibly designed according to actual needs, and can be the same or different to meet the personalized needs of different users.

[0070] Reference Fig. 9 At the same time, in order to increase the rotation stability of the gear adjustment disk 3342, a plurality of positioning protrusions 313 are also provided on the upper surface of the drainage base 31. The plurality of positioning protrusions 313 are arranged along the circumferential direction, and four positioning protrusions 313 correspond to the four drainage holes respectively.

[0071] Reference Figure 6 and Fig. 9 The buffer mechanism 35 is located between the gear adjustment disk 3342 and the plurality of positioning protruding rings 313. The buffer mechanism 35 includes an annular flexible buffer pad 351. The flexible buffer pad 351 is provided with a plurality of second through-holes 3511 arranged along the circumferential direction. The second through-holes 3511 correspond to the positioning protruding rings 313 one by one. Each positioning protruding ring 313 is penetrated through the second through-holes 3511. Meanwhile, the flexible buffer pad 351 is covered on the outer side walls of the plurality of positioning protruding rings 313. The flexible buffer pad 351 protects the gear adjustment disk 3342 and the drainage base 31, thereby extending the service life of the gear adjustment disk 3342 and the drainage base 31.

[0072] Reference Figure 6 , Figure 7 and Fig. 9The buffer mechanism 35 further 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 disk 3342. A second rotation groove 3521 is provided at the top of the first concave-convex seat 352. A plurality of first protrusions 3522 are arranged at the bottom of the second rotation groove 3521 along the circumferential direction. A first groove 3523 is formed between two adjacent protrusions. The structures of the first protrusion 3522 and the first groove are both triangular. The second concave-convex seat 353 is rotatably connected to the second rotation groove 3521. The shape of the end of the second concave-convex seat 353 is completely consistent with the structure of the top of the first concave-convex seat 352. This enables the gear adjustment disk 3342 to be smoothly rotatably connected to the drainage base 31, which not only ensures the smoothness of the rotation of the gear adjustment disk 3342, but more importantly, it plays a good protective role on the soft buffer pad, avoiding wear or damage caused by long-term or frequent contact.

[0073] Reference Figure 4 and Figure 6 , the diverter mechanism 36 includes a diverter seat 361, and the inner side wall of the bottom cover 12 is integrally formed with a plurality of bolt columns, and the surfaces of the plurality of bolt columns are in contact with the surface of the diverter seat 361, so as to fix the diverter seat 361 inside the bottom cover 12. In this embodiment, the diverter seat 361 is located between the filter device 2 and the gear adjustment mechanism 33. A positioning groove 362 is provided at the center of the top of the diverter seat 361, and a third positioning ring 232 is integrally formed on the lower surface of the second sleeve 23, and the outer side wall of the third positioning ring 232 is in contact with the inner side wall of the positioning groove 362, so as to fix the second sleeve 23 on the diverter seat 361. At the same time, a sealing ring is provided between the outer side wall of the third positioning ring 232 and the inner side wall of the positioning groove 362, so as to increase the sealing between the two.

[0074] Reference Figure 2 , Figure 4 and Figure 6 The second sleeve 23, the third positioning ring 232 and the diverter seat 361 are enclosed to form a water storage chamber 363. The bottom of the positioning groove 362 is provided with a first diverter hole 364 and a second diverter hole 365, which are independent of each other and not connected to each other. The first diverter hole 364 directly guides the clean water in the water storage chamber 363 to the gear adjustment device 3. After precise gear adjustment, the water flow finally falls elegantly on the water outlet panel 123, bringing a delicate and varied water outlet experience to the user.

[0075] Reference Figure 2 and Figure 6A fragrance release device 5 is embedded in the second diversion hole 365. The design inspiration of this mechanism comes from the push-type cylindrical pen. It is not only easy to operate, but also has multiple functions. It can flexibly store various items such as seasonings, aromatherapy tablets, soaps, etc., adding a unique charm to the water flow. When the user wants to replace these flavoring items, just press lightly to easily complete the installation and removal of the fragrance release device 5, so as to realize the replacement of the items in the fragrance release device 5, which is convenient and fast.

[0076] It is worth mentioning that the second diversion hole 365 serves as a bridge connecting the water storage chamber 363 and the fragrance release device 5, which ensures that the water can flow smoothly through the fragrance release device 5, fully absorb the fragrance or taste therein, and then present this carefully modulated water flow to the user through the water outlet panel 123. This not only improves the quality of water use, but also adds a different interest and enjoyment to daily life.

[0077] The implementation principle of the above embodiment is as follows: this top spray shower achieves the purification of shower water quality and the flexible adjustment of water flow rate and spray mode through its carefully designed housing device 1, built-in filtering device 2 and gear adjustment device 3. Water enters from the water inlet 111 at the end of the top cover 11, and after impurities are intercepted by the filtering device 2, it flows into the gear adjustment device 3 in the bottom cover 12 through the drainage channel. The user can adjust the gear to change the water flow rate and spray mode according to needs. Finally, clean and personalized water flows out from the first water outlet 124 at the end of the bottom cover 12, which not only ensures the cleanliness of the shower water quality, but also improves the personalization and comfort of the shower experience.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
