[0050] With reference to Figure 2 The water inlet mechanism 13 further comprises a water inlet valve 133. The inner side wall of the water inlet valve 133 is provided with a water inlet channel 1331, one end of which penetrates the outside, and the other end of which is in communication with the first water inlet hole 1325. The water inlet valve 133 comprises a second connecting cylinder 1332 and a ball head seat 1333. The bottom end of the second connecting cylinder 1332 is integrally formed with the top end of the ball head seat 1333, and the water inlet channel 1331 penetrates the second connecting cylinder 1332 and the ball head seat 1333. The ball head seat 1333 is fixed in the inner portion of the mounting ring 131, and the second connecting cylinder 1332 is located outside the top cover 11. The inner side wall of the second connecting cylinder 1332 is provided with internal threads, which are used for threadedly connecting with an external connecting member (such as a water pipe), so as to realize water input.

[0051] With reference to Figure 2The inner part of the mounting ring 131 is provided with a first clamping piece 134, the inner side wall of the second connecting barrel 1332 is provided with a second clamping piece 135, and the ball head seat 1333 is located between the first clamping piece 134 and the second clamping piece 135. The first clamping piece 134 and the second clamping piece 135 have a clamping effect on the ball head seat 1333, so as to fix the water inlet valve 133 to the water inlet end of the top cover 11. The first clamping piece 134 and the second clamping piece 135 are annular, and an arc-shaped groove is formed on the side of the first clamping piece 134 and the second clamping piece 135 close to the ball head seat 1333, so as to increase the contact area between the first clamping piece 134, the second clamping piece 135 and the ball head seat 1333, thereby increasing the firmness of the water inlet valve 133 installation. At the same time, the inner side wall of the water inlet channel 1331 is integrally formed with a limiting ring 136, and the limiting ring 136 abuts against the bottom end of the second clamping piece 135, so as to further increase the firmness of the first clamping piece 134 and the second clamping piece 135 clamping the ball head seat 1333.

[0052] With reference to Figure 2 The filter device 2 comprises a filter core 21, a first sleeve 22 and a second sleeve 23. The filter core 21 is in a cylindrical shape, and the first sleeve 22 and the second sleeve 23 are respectively sleeved on both ends of the filter core 21. The first sleeve 22 and the second sleeve 23 are fixed with the filter core 21, and the first sleeve 22 is fixed on the inner side wall of the connecting ring 1323, so as to realize the installation of the filter device 2 in the top cover 11.

[0053] With reference to 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 in the length direction of the axis. At the same time, the inner side wall of the positioning barrel 1322 and the connecting ring 1323 is provided with a plurality of L-shaped second flanges 231 in the circumferential direction, and the plurality of second flanges 231 are arranged in the circumferential direction. The outer side wall of the first flange 221 abuts against the outer side wall of the second flange 231, so as to ensure the gap between the filter device 2 and the positioning piece 132, and ensure the smooth flow of water. The center of the second sleeve 23 is provided with a second water outlet hole 233, which allows the water to be smoothly conveyed to the gear adjusting device 3 through the drainage channel after passing through the filtering effect of the filter core 21.

[0054] With reference to Figure 2 and Figure 3The bottom cover 12 comprises a bearing ring 121, a cover body 122 and a water outlet panel 123. The top end of the cover body 122 is integrally formed with the bearing ring 121. The water outlet panel 123 is detachably connected to the bottom end of the cover body 122. The water outlet panel 123 is provided with a plurality of first water outlet holes 124. The bottom end of the top cover 11 is provided with an opening. The bottom end of the top cover 11 abuts against the top end of the bottom cover 12. The bottom cover 12 is provided with a clamping device 4 for clamping and fixing the top cover 11. The clamping device 4 increases the convenience of the workers in installing and dismounting the top cover 11, thereby increasing the convenience of the workers in replacing the filter device 2.

[0055] With reference to the drawings Figure 2 and Figure 3 The clamping device 4 comprises two clamping mechanisms 41 and two unlocking mechanisms 42. The two clamping mechanisms 41 are symmetrical to each other. Each clamping mechanism 41 comprises a clamping half-ring 411 and a first elastic member 412. The clamping half-ring 411 is cleverly arranged between the bearing ring 121 and the gear adjusting device 3, and plays a key connecting role. The 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 side wall of the clamping half-ring 411, and the other end of the first elastic member 412 firmly abuts against the inner side wall of the cover body 122. The two clamping half-rings 411 can move towards each other under the elastic force of the first elastic member 412, thereby clamping the positioning cylinder 1322, and realizing the stable connection between the top cover 11 and the bottom cover 12.

[0056] With reference to the drawings Figure 2 and Figure 3 The outer side wall of the positioning cylinder 1322 is 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 from moving relative to the positioning cylinder 1322, and further increases the firmness of the clamping mechanism 41.

[0057] With reference to the drawings Figure 2 and Figure 3 In addition, the bottom cover 12 is also provided with two symmetrical unlocking mechanisms 42 for conveniently unlocking and separating the top cover 11 and the bottom cover 12 when needed. Each unlocking mechanism 42 comprises a first rotating member 421 and a button 422. The first rotating member 421 is rotationally connected with the bottom cover 12. The button 422 is slidingly connected 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.

[0058] With reference to the drawings Figure 2 and Figure 3, the first rotating piece 421 comprises a rotating shaft 4211, a driving block 4212, a driven block 4213 and a linkage block 4214. One end of the driving block 4212 is integrally formed with the rotating shaft 4211, 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 linkage block 4214 is integrally formed at an end of the driven block 4213 away from the rotating shaft 4211. The inner side wall of the bottom cover 12 is integrally formed with two symmetrical supports 125, and the rotating shaft 4211 penetrates through the supports 125 and is rotationally connected with 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. The cover body 122 is provided with a through sliding hole 126 on each of the opposite sides, corresponding to the buttons 422. The buttons 422 penetrate through the sliding holes 126 and are in sliding cooperation with the cover body 122, and the bottom end of the button 422 abuts against an end of the driving block 4212 away from the rotating shaft 4211. Therefore, the user only needs to press the button 422 slightly, and the linkage block 4214 can be driven to move through the rotation of the first rotating piece 421, so that the clamping half-rings 411 are easily unlocked and the top cover 11 and the bottom cover 12 are separated, thereby facilitating the mutual separation of the top cover 11 and the bottom cover 12, and achieving manual replacement of the filter device 2.

[0059] With reference to Figure 2 and Figure 3 , the outer side wall of each end of the linkage block 4214 is provided with a first inclined surface 4215, and the inner side wall of each end of the 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 abut with each other. The two symmetrical unlocking mechanisms 42 work in cooperation with the first rotating piece 421 and the button 422. The rotating shaft 4211 is rotationally connected with the symmetrical supports 125 in the inner side of the bottom cover 12, and the V-shaped driving block 4212 and the driven block 4213 enable the linkage block 4214 to move with the rotation of the first rotating piece 421 and be inserted into the gap between the two clamping half-rings 411, and the first inclined surface 4215 at the end of the linkage block 4214 and the second inclined surface 413 on the inner side wall of the clamping half-ring 411 abut and 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 driving block 4212, thereby driving the entire first rotating piece 421 and the linkage block 4214 to move, and finally achieving the unlocking function.

[0060] With reference to Figure 2 , in order to prevent the button 422 from accidentally falling off during use, an anti-falling ring 4221 is integrally formed on the outer side wall of each end of the button 422 close to the first rotating piece 421. The diameter of the anti-falling ring 4221 is greater than the diameter of the button 422, which provides additional support and fixation for the button 422, ensuring the stability and reliability of the button 422.

[0061] With reference to Figure 6 , the gear adjusting device 3 comprises a drainage base 31, a mounting seat 32, a gear adjusting mechanism 33, a reset mechanism 34, a buffer mechanism 35 and a shunt mechanism 36.

[0062] With reference to Figure 6 , the drainage base 31 comprises a drainage base plate 311 and a ring-shaped part 312 which is integrally formed on the upper surface of the drainage base plate 311. The mounting seat 32 is fixed on the ring-shaped part 312, and a cavity 37 is formed between the mounting seat 32, the ring-shaped part 312 and the drainage base 31. The gear adjusting mechanism 33 is arranged on the mounting seat 32, part of which is located outside the cavity 37 and part of which is located inside the cavity 37.

[0063] With reference to Figure 2 and Figure 6 , the gear adjusting mechanism 33 comprises a driving rotating seat 331, an intermediate rotating seat 332, a ring rotating seat 333 and a gear adjusting seat 334. The driving rotating seat 331 is arranged to rotate between the shunt mechanism 36 and the mounting seat 32, the bottom of the shunt mechanism 36 abuts against the upper surface of the driving rotating seat 331, and the upper surface of the mounting seat 32 abuts against the lower surface of the driving rotating seat 331, thereby increasing the stability of the rotation of the driving rotating seat 331. The ring rotating seat 333 rotates intermittently with the mounting seat 32, and rotates 20° each time. The intermediate rotating seat 332 is located between the driving rotating seat 331 and the ring rotating seat 333, is arranged through the mounting seat 32 and is rotationally connected with the mounting seat 32, rotates 20° each time, and is inserted and matched with the ring rotating seat 333, thereby ensuring that the two rotate synchronously. The driving rotating seat 331 is rotationally connected with the intermediate rotating seat 332, and drives the intermediate rotating seat 332 to rotate intermittently in the process of rotation. The intermediate rotating seat 332 is connected with the gear adjusting seat 334 in the form of insertion and matching, and drives the gear adjusting seat 334 to rotate 20° each time in the process of rotation.

[0064] With reference to Figure 6 and Figure 7 , the driving rotating seat 331 is provided with three hollow grooves 3311 in the circumferential direction, and the inner side wall of each hollow groove 3311 is integrally formed with an inclined elastic driving part 3312. A third inclined surface 3313 is formed on the surface of each elastic driving part 3312 close to the intermediate rotating seat 332, so that when the driving 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, 20° each time.

[0065] With reference to Figure 6 , Figure 7 andFigure 8 The intermediate rotating seat 332 comprises a second rotating part 3321 and a first inserting part 3322 which are integrally formed, thereby ensuring the integrity and strength of the structure. The first inserting part 3322 is inserted into the gear adjusting seat 334, thereby increasing the convenience of mounting and dismounting the two parts and ensuring the synchronous rotation of the intermediate rotating seat 332 and the gear adjusting seat 334. The upper surface of the second rotating part 3321 is circumferentially provided with nine center-symmetrical driven ramps 3323, and the upper surface of each driven ramp 3323 is provided with a guide arc surface 3324. The same end of the nine driven ramps 3323 is provided with a vertical positioning end surface 3325. 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 driving rotating seat 331 rotates clockwise, the third inclined surface 3313 rotates relative to the guide arc surface 3324, and at this time, the driving rotating seat 331 does not drive the intermediate rotating seat 332 to rotate. When the driving rotating seat 331 rotates counterclockwise, the end of the elastic driving part 3312 abuts against the positioning end surface 3325 of the driven ramp 3323, and at this time, the driving rotating seat 331 drives the intermediate rotating seat 332 to rotate, and each rotation is 20°.

[0066] With reference to Figure 6 , Figure 7 and Figure 8 The annular rotating seat 333 comprises a rotating ring 3331 which is rotationally connected with the mounting seat 32. Specifically, the upper surface of the mounting seat 32 is provided with a first rotating groove 321, the depth of the first rotating groove 321 is less than the thickness of the mounting seat 32, and the rotating ring 3331 is rotationally arranged in the first rotating groove 321. In the middle of the first rotating groove 321, a first through hole 323 is further provided for the intermediate 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. The bottom of the first rotating groove 321 is integrally formed with an annular shaft 322, the rotating ring 3331 is sleeved on the annular shaft 322, and the rotating ring 3331 is rotationally connected with the annular shaft 322.

[0067] With reference to Figure 6 , Figure 7 and Figure 8The rotating ring 3331 is integrally formed with a plurality of insertion portions 3332 on the side facing the driving rotating seat 331, and the driving rotating seat 331 is provided with a plurality of insertion grooves corresponding to the insertion portions 3332. The insertion portions 3332 and the insertion grooves are matched by insertion, so that the driving rotating seat 331 can drive the annular rotating seat 333 to rotate synchronously every 20°. In addition, the outer side wall of the rotating ring 3331 is integrally formed with three arc-shaped first stoppers 3333. The first stoppers 3333 have the ability to elastically deform and can interact with the nine driven inclined platforms 3323 arranged along the circumferential direction of the inner side wall of the first rotating groove 321. The nine driven inclined platforms 3323 are centrally symmetrically distributed, and each driven inclined platform 3323 includes a guide arc surface 3324 and a positioning end surface 3325. This ensures that the intermediate rotating seat 332 can only rotate counterclockwise and cannot rotate clockwise.

[0068] With reference to Figure 6 , Figure 7 and Figure 8 , specifically, during the counterclockwise rotation of the intermediate rotating seat 332, the outer side wall of the first stopper 3333 abuts against the inner side wall of the guide arc surface 3324 and smoothly rotates along the guide arc surface 3324 every 20°. When attempting to rotate the intermediate rotating seat 332 clockwise, the positioning end surface 3325 of the driven inclined platform 3323 will block the end of the first stopper 3333, thereby preventing clockwise rotation. Not only does this ensure smooth rotation, but it also provides effective rotation direction restriction.

[0069] With reference to Figure 6 , Figure 7 and Figure 8 , when the driving rotating seat 331 and the intermediate rotating seat 332 rotate relative to each other, the third inclined surface 3313 of the elastic driving portion 3312 will abut against the guide arc surface 3324 of three driven inclined platforms 3323, respectively. This abutment relationship allows the two to interact during rotation. In particular, when the driving rotating seat 331 rotates clockwise, the direction of the interaction force between the elastic driving portion 3312 and the driven inclined platform 3323 is not sufficient to overcome other resistance, so the driving rotating seat 331 will not drive the intermediate rotating seat 332 to rotate. However, when the driving rotating seat 331 rotates counterclockwise, the end of the elastic driving portion 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 does this achieve rotation direction restriction, but it also ensures the reliability and accuracy of the rotation action.

[0070] With reference to Figure 8 and Figure 9The reset mechanism 34 comprises a driving seat 341 and a second elastic member 342. One end of the driving seat 341 is fixedly connected with the driving rotating seat 331. The sidewall of the bottom cover 12 is provided with a sliding hole 126 through which the driving seat 341 passes. The sliding hole 126 extends along the horizontal direction. The driving seat 341 is in sliding cooperation with the sliding hole 126 during rotation. One end of the second elastic member 342 is connected with the driving seat 341, and the other end of the second elastic member 342 is connected with the drainage base 31. In this embodiment, the second elastic member 342 is specifically a spring. When the driving seat 341 rotates from one end of the sliding hole 126 to the other end of the sliding hole 126, the driving rotating seat 331 just rotates by 20°, so as to realize adjustment of one gear. When external force acts on the driving seat 341, the driving seat 341 rotates back to the initial position under the elastic force of the second elastic member 342, so as to facilitate the adjustment of the next gear.

[0071] With reference to Figure 8 The gear adjustment seat 334 comprises a second plug-in member 3341 and a gear adjustment disc 3342. The bottom end of the second plug-in member 3341 is integrally formed with the upper surface of the gear adjustment disc 3342. The second plug-in member 3341 is in plug-in cooperation with the first plug-in member 3322, so as to connect the gear adjustment seat 334 and the intermediate rotating seat 332 together, thereby ensuring that the intermediate rotating seat 332 can rotate the gear adjustment seat 334 during rotation, so as to realize adjustment of the water outlet mode.

[0072] With reference to Figure 9 and Figure 9The three second water inlets 3343 are circumferentially arranged on the gear adjusting disc 3342, and the three first water outlets 124 are circumferentially and evenly distributed at equal intervals, so that the included angle between the center line of the adjacent two second water inlets 3343 and the center of the gear adjusting disc 3342 is exactly 60°. The first, second, third and fourth water outlets 3111, 3112, 3113 and 3114 are circumferentially arranged on the water drainage base plate 311 of the water drainage base 31 at equal intervals. The center of the arc line where the four water outlets are located is defined as the center point. The center line of the first water outlet and the center point is defined as the first line segment, the center line of the second water outlet and the center point is defined as the second line segment, the center line of the third water outlet and the center point is defined as the third line segment, and the center line of the fourth water outlet and the center point is defined as the fourth line segment. The included angle between the first line segment and the second line segment is 20°, the included angle between the second line segment and the third line segment is 20°, the included angle between the third line segment and the fourth line segment is 20°, and the included angle between the first line segment and the third line segment is 60°. Since the three second water inlets 3343 and the three first water outlets 124 are circumferentially and evenly distributed at equal intervals, 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 is ensured that the gear adjusting disc 3342 can realize three different water outlet gears when rotating, so as to ensure that the gear adjusting disc 3342 can realize water outlet at three different gears during rotation.

[0073] Referring to Figure 6 and Figure 9Meanwhile, the lower surface of the drainage base 31 is sequentially provided with a first isolation ring 3115, a second isolation ring 3116, a third isolation ring 3117 and a sealing ring 3118 from inside to outside in sequence, and the outer side wall of the sealing ring 3118. Among them, 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 at this time, the maximum gear water outlet 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 are blocked by the drainage base 31. Users can easily adjust the water outlet form according to actual needs to achieve three different water outlet effects such as spraying, rain, and jetting. 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, which can be the same or different to meet the individual needs of different users.

[0074] With reference to Figure 6 Meanwhile, in order to increase the stability of the rotation of the gear adjustment disc 3342, the upper surface of the drainage base 31 is also provided with a plurality of positioning convex rings 313, and the plurality of positioning convex rings 313 are arranged in a circumferential direction. Among them, four positioning convex rings 313 are respectively corresponding to four drainage holes.

[0075] With reference to Figure 7 And Figure 9 The buffer mechanism 35 is located between the gear adjustment disc 3342 and the plurality of positioning convex rings 313, and the buffer mechanism 35 includes a flexible buffer pad 351 in the form of a ring, and a plurality of second through holes 3511 arranged in a circumferential direction are arranged on the flexible buffer pad 351 in a circumferential direction. The second through hole 3511 corresponds to the positioning convex ring 313 one by one, and each positioning convex ring 313 is arranged in the second through hole 3511. Meanwhile, the flexible buffer pad 351 is wrapped on the outer side wall of the plurality of positioning convex rings 313, and the flexible buffer pad 351 has a protective effect on the gear adjustment disc 3342 and the drainage base 31, thereby prolonging the service life of the gear adjustment disc 3342 and the drainage base 31.

[0076] With reference to Figure 4 , Figure 6 And Figure 2The buffer mechanism 35 further comprises 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 adjusting disc 3342. The top end of the first concave-convex seat 352 is provided with a second rotating groove 3521, and the groove bottom of the second rotating groove 3521 is provided with a plurality of first protrusions 3522 in the circumferential direction. The first protrusions 3522 and a groove are both triangular in structure. The second concave-convex seat 353 is rotationally connected with the second rotating groove 3521, and the end portion of the second concave-convex seat 353 is completely matched with the structure of the top end of the first concave-convex seat 352. This makes the gear adjusting disc 3342 be rotationally connected with the drainage base 311 smoothly, which not only ensures the smoothness of the rotation of the gear adjusting disc 3342, but also protects the soft buffer pad well and avoids abrasion or damage caused by long-time or frequent contact.

[0077] With reference to Figure 4 and Figure 6 , the shunt mechanism 36 comprises a shunt seat 361. The inner side wall of the bottom cover 12 is integrally provided with a plurality of bolt columns, and the surfaces of the bolt columns are all abutted against the surface of the shunt seat 361, so as to fix the shunt seat 361 inside the bottom cover 12. In this embodiment, the shunt seat 361 is located between the filter device 2 and the gear adjusting mechanism 33. The center of the top end of the shunt seat 361 is provided with a positioning groove 362, and the lower surface of the second sleeve 23 is integrally provided with a third positioning ring 232. The outer side wall of the third positioning ring 232 is abutted against the inner side wall of the positioning groove 362, so as to fix the second sleeve 23 on the shunt seat 361. Meanwhile, a sealing ring is arranged 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 property therebetween.

[0078] With reference to Figure 2 , Figure 6 and ​ , the second sleeve 23, the third positioning ring 232 and the shunt seat 361 form a water storage cavity 363. The groove bottom of the positioning groove 362 is provided with a first shunt hole 364 and a second shunt hole 365 which are independent and not communicated with each other. The first shunt hole 364 directly guides the clean water in the water storage cavity 363 to the gear adjusting device 3, and after precise gear adjustment, the water flow is finally elegantly sprinkled on the water outlet panel 123, so as to bring the user a delicate and variable water outlet experience.

[0079] With reference to ​ and ​In the embodiment, the second shunt hole 365 is sequentially arranged through the shunt mechanism 36, the mounting seat 32 and the drainage base 311, and a fragrance releasing device 5 is embedded in the second shunt hole 365. The mechanism is inspired by a push-type cylindrical pen, and is not only easy to operate, but also has multiple functions. The fragrance releasing device 5 can flexibly store various objects such as seasoning medicine, aromatherapy tablets and soap, and add a unique flavor to the water flow. When the user wants to replace the objects, the fragrance releasing device 5 can be easily installed and detached by pressing, so that the objects in the fragrance releasing device 5 can be replaced, which is convenient and fast.

[0080] It is worth mentioning that the second shunt hole 365 serves as a bridge connecting the water storage cavity 363 and the fragrance releasing device 5, which ensures that the water flow can smoothly flow through the fragrance releasing device 5, fully absorb the aroma or taste therein, and then present the carefully prepared water flow to the user through the water outlet panel 123. Not only the quality of the water is improved, but also a unique interest and enjoyment is added to daily life.

[0081] The implementation principle of the above embodiment is that the detachable connection of the top cover 11 and the bottom cover 12 enables the user to conveniently open the shell device 1 for internal cleaning and maintenance. At the same time, the filter element 21 is installed in the top cover 11, which facilitates the user to quickly replace the filter element 21, and improves the use convenience and maintenance efficiency of the equipment.

[0082] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
