Description

Technical Field

[0001] This application relates to the field of liquid application container technology, and in particular to a rollerball applicator bottle. Background Technology

[0002] Rollerball applicators, as a convenient tool for applying liquids and ointments, have been widely used in various fields such as beauty and skincare, pharmaceutical care, and daily cleaning due to their core advantages of "rolling to apply, even application, and avoiding direct hand contact with contaminated products". They are compatible with various dosage forms such as essential oils, lotions, and ointments.

[0003] In existing technologies, the core structure typically includes a liquid storage bottle, a ball bearing seat at the bottle mouth, a ball bearing, and a sealing cap. When in use, the user inverts the bottle and uses the ball bearing to roll on the application surface to bring out the liquid inside the bottle and apply it evenly.

[0004] However, the dimensions of the drainage channel in the existing rollerball applicator bottle's drainage structure remain fixed. The dispensing process relies on the liquid's own weight and capillary action. In actual use, due to inherent differences in factors such as hand pressure, application angle, and rolling speed, the interaction between the rollerball and the application area is constantly changing. The existing fixed drainage structure cannot adapt to these changes. As a result, regardless of the user's rolling force or speed, the amount of liquid obtained per unit area is passive and random, failing to meet the differentiated liquid supply requirements of different usage scenarios. This affects the controllability of the product's effect, leads to liquid waste or the need for repeated application, and reduces the product's flexibility. Summary of the Invention

[0005] To enable dynamic adjustment of the liquid supply volume according to user needs, thereby meeting the differentiated liquid supply requirements of different usage scenarios and improving the flexibility of product use, this application provides a rollerball applicator bottle.

[0006] The rollerball applicator provided in this application adopts the following technical solution:

[0007] A roller-type applicator includes a storage bottle, a shell, a roller seat, a roller, and a sealing cap. The storage bottle has a dispensing tube at its opening, one end of which is fixedly mounted on the side wall of the roller seat and connected to the dispensing port of the roller seat. A baffle is fixedly mounted at the opening of the dispensing tube, and the baffle has multiple dispensing holes (first type). A rotating plate is rotatably mounted on the baffle, and the rotating plate has multiple dispensing holes (second type). Each of the second dispensing holes corresponds one-to-one with a first dispensing hole, and the second dispensing holes can gradually overlap with the first dispensing holes. A driving mechanism for rotating the rotating plate is provided inside the dispensing tube.

[0008] By adopting the above technical solution, when the user uses the applicator and presses the ball, the pressure on the ball triggers the drive mechanism, which then starts working, causing the rotating plate to rotate relative to the fixed baffle. As the rotating plate rotates, the relative position between the second liquid outlet on it and the first liquid outlet on the baffle changes, gradually transitioning from a completely misaligned state to a completely overlapping state, thus realizing stepless adjustment of the cross-sectional area of ​​the liquid outlet channel. The liquid flow rate is controlled by the operating force applied by the user to the ball, allowing the liquid output to be dynamically adjusted according to the user's needs, thereby meeting the differentiated liquid supply requirements of different usage scenarios and improving the flexibility of product use.

[0009] Preferably, the driving mechanism includes a threaded rod and a threaded sleeve. A support plate is fixedly disposed on the inner wall of the outlet pipe. The threaded rod is slidably disposed on the support plate. A ball is slidably disposed on the end of the threaded rod near the ball bearing. The ball bearing is in contact with and slidably disposed on the surface of the ball bearing. One end of the threaded sleeve is fixedly disposed on the rotating plate, and the threaded sleeve is threadedly engaged with the threaded rod. A guide block is fixedly disposed on the side wall of the threaded rod, and the guide block is slidably disposed on the support plate. The driving mechanism also includes a first reset component that resets the threaded rod.

[0010] By adopting the above technical solution, when the ball is pressed, its surface pushes the ball, forcing the threaded rod to move linearly along the axial direction. Due to the limit of the guide block, the threaded rod can only slide and cannot rotate. The linear movement of the threaded rod drives the threaded sleeve that it is in contact with to rotate through the thread. The rotation of the threaded sleeve directly drives the rotating plate that is fixed to it to rotate synchronously, thereby adjusting the alignment area of ​​the liquid outlet hole. When the pressure disappears, the first reset component pushes the threaded rod and the ball to reset, driving the entire mechanism to move in the opposite direction, closing or reducing the flow channel. The whole process reduces the difficulty of rotating the rotating plate.

[0011] Preferably, a support block slides within the side wall of the ball bearing seat, and a drive assembly for moving the support block is provided within the ball bearing seat, wherein the support block can abut against the surface of the ball bearing.

[0012] By adopting the above technical solution, when the ball is not in use or needs to be fixed, the user can drive the support block to extend through the drive component, so that its end abuts against the surface of the ball. During storage or transportation, the support block can hold the ball in place to prevent it from rotating accidentally and causing liquid leakage.

[0013] Preferably, the driving assembly includes a driving plate, a first driving block, and a second driving block. The driving plate is slidably disposed outside the ball bearing seat. One end of the first driving block is fixedly disposed on the driving plate and slidably disposed on the side wall of the ball bearing seat. One end of the second driving block is fixedly disposed on the support block. The second driving block has an inclined surface at its end near the first driving block, and the second driving block can slide and engage with the first driving block through its inclined surface. The end of the second driving block near the first driving block can abut against the first driving block. The driving assembly also includes a reset member for resetting the support block.

[0014] By adopting the above technical solution, when not in use, the user moves the drive plate downward, causing drive block one to move. The inclined surfaces at the ends of drive block one and drive block two interact, driving the longitudinal movement of drive block one, through the inclined surfaces, to drive drive block two and the support block connected to it to move towards the ball, thereby causing the support block to extend and finally abut against the ball. When in use, the user moves the drive plate upward, and after the drive plate moves drive block one away from drive block two, the reset component automatically retracts the support block back to its original position. The whole process reduces the difficulty of moving the support block.

[0015] Preferably, a stop block is fixedly provided on the side wall of the drive block one, the stop block slides inside the side wall of the ball seat, and the stop block can abut against the inner wall of the ball seat.

[0016] By adopting the above technical solution, the stop block fixed on one side wall of the drive block slides within the side wall of the ball bearing seat, thereby reducing the possibility of the drive plate separating from the ball bearing seat.

[0017] Preferably, the inner sidewall of the top of the sealing cover is provided with a plurality of slide rods that slide along its top horizontal plane. The plurality of slide rods slide along a plurality of diameter directions on the horizontal cross-section of the ball. An elastic cleaning strip for cleaning the surface of the ball is detachably connected to the slide rod. The elastic cleaning strip can slide on the surface of the ball.

[0018] By adopting the above technical solution, before the sealing cap is put back on the bottle, multiple sliding rods and cleaning strips gather at the center of the sealing cap. Then, when the sealing cap is put back on the bottle, under the user's pressure, the cleaning strips come into contact with the ball and remain in contact. Multiple sliding rods and the elastic cleaning strips at their ends automatically spread out from the center of the ball along multiple diameter directions of its horizontal cross section around the ball. The sliding rods can slide horizontally along the inner side wall of the top of the sealing cap, so that the cleaning strips can fit tightly against the spherical curved surface of the ball, thereby facilitating the scraping and cleaning of the ball surface, preventing residual liquid from drying, crystallizing or getting dusty, and avoiding clogging of the outlet and contamination of the liquid for the next use. After removing the sealing cap, the user can disassemble the cleaning strips for cleaning and replacement, so as to repeatedly clean the ball.

[0019] Preferably, a plurality of guide rods are fixedly provided on the top inner sidewall of the sealing cover, and the plurality of guide rods are provided in a one-to-one correspondence with the plurality of slide rods. The plurality of guide rods are respectively arranged horizontally along a plurality of diameter directions on the horizontal cross-section of the ball, and the guide rods pass through and slide on the sidewall of the slide rods.

[0020] By adopting the above technical solution, the guide rod is fixedly set along the diameter direction of the horizontal cross section of the ball, so that all the slide rods move along the radial direction of the ball, thereby improving the stability of the slide rod movement.

[0021] Preferably, a return spring is sleeved on the guide rod, and the two ends of the return spring are respectively fixed to the slide rod and the top inner wall of the sealing cover.

[0022] By adopting the above technical solution, when the cover is closed and the slide bar moves outwards to the ball bearings, the return spring is stretched. Then, when the cover is removed, the elastic force of the return spring can pull the slide bar back to the center position of the sealing cover, so that the cleaning strip can clean the surface of the ball bearings again when the cover is closed next time.

[0023] Preferably, a plug-in block slides vertically at the end of the slide rod, and a slot for the plug-in block is provided on the inner side wall of the top of the sealing cover at the farthest position of the slide rod's sliding path. A push spring is provided inside the side wall of the slide rod, and the two ends of the push spring abut against the plug-in block and the inner wall of the slide rod, respectively.

[0024] By adopting the above technical solution, when the sealing cover is fully closed, the return spring is in a stretched state. Therefore, under the elastic pull of the return spring, the slide rod and cleaning strip tend to move towards the center of the ball. At the same time, due to the curved surface of the ball, the slide rod and cleaning strip also tend to push the ball downward, causing the sealing cover to fall off and separate from the ball. Therefore, when the sealing cover is fully closed, the slide rod and cleaning strip move to the edge of the ball. At this time, the set insertion block is inserted into the slot on the sealing cover under the elastic force of the push spring, so that the slide rod always stays at the edge of the ball, greatly reducing the force of the slide rod and cleaning strip on the ball, and reducing the possibility of the sealing cover separating from the ball and the outer shell.

[0025] Preferably, a push plate is vertically slidable on the outer side wall of the top of the sealing cover, and a plurality of push blocks are fixedly provided on the side wall of the push plate. The push blocks slide vertically inside the side wall of the sealing cover, and the plurality of push blocks are arranged in a one-to-one correspondence with the plurality of plug-in blocks. The push blocks can abut against the plug-in blocks. A second reset component is provided inside the side wall of the sealing cover to reset the push plate.

[0026] By adopting the above technical solution, when the user removes the sealing cover, the user can press the push plate into the sealing cover. The push plate drives the push block to move, and the push block then contacts the plug block and pushes the plug block out of the slot. Subsequently, the slide rod can be reset to the center position of the sealing cover under the elastic force of the reset spring, so as to clean the ball again. When the user releases the force on the push plate, the push plate and the push block can be reset under the action of the second reset component, so as to push the plug block to move again.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the user uses the applicator and presses the roller, the pressure on the roller triggers the drive mechanism, which then starts working, causing the rotating plate to rotate relative to the fixed baffle. As the rotating plate rotates, the relative position between the second liquid outlet on it and the first liquid outlet on the baffle changes, gradually transitioning from a completely misaligned state to a completely overlapping state, thus realizing stepless adjustment of the cross-sectional area of ​​the liquid outlet channel. The liquid flow rate is controlled by the operating force applied by the user to the roller, allowing the liquid output to be dynamically adjusted according to the user's needs, thereby meeting the differentiated liquid supply requirements of different usage scenarios and improving the flexibility of product use.

[0029] 2. When not in use or when the ball needs to be fixed, the user can drive the support block to extend through the drive component, so that its end abuts against the surface of the ball. During storage or transportation, the support block can hold the ball in place to prevent accidental rotation and liquid leakage.

[0030] 3. Before the sealing cap is replaced on the bottle, multiple sliding rods and cleaning strips converge at the center of the sealing cap. Subsequently, when the sealing cap is replaced on the bottle, the cleaning strips come into contact with and remain in close contact with the ball bearing under the user's pressure. The multiple sliding rods and the elastic cleaning strips at their ends automatically spread out from the center of the ball bearing along multiple diameter directions of its horizontal cross-section around the ball bearing. The sliding rods can slide horizontally along the inner side wall of the top of the sealing cap, allowing the cleaning strips to fit tightly against the spherical curved surface of the ball bearing. This facilitates scraping and cleaning of the ball bearing surface, preventing residual liquid from drying, crystallizing, or becoming contaminated with dust, and avoiding clogging of the outlet and contamination of the liquid for the next use. After removing the sealing cap, the user can disassemble the cleaning strips for cleaning and replacement, facilitating repeated cleaning of the ball bearing. Attached Figure Description

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0041] This application discloses a rollerball applicator, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes a storage bottle 1, a shell 2, a ball bearing seat 3, a ball bearing 4, and a sealing cap 5. A liquid outlet pipe 6 is vertically arranged at the mouth of the storage bottle 1. The top side wall of the liquid outlet pipe 6 is fixedly connected to the bottom side wall of the ball bearing seat 3, and the liquid outlet pipe 6 is connected to the liquid outlet of the ball bearing seat 3.

[0042] like Figure 3 and Figure 4As shown, a baffle 7 is fixedly connected to the side wall of the bottom end of the outlet pipe 6. Multiple outlet holes 8 are provided on the baffle 7. A rotating plate 70 is rotatably provided on the baffle 7. Multiple outlet holes 9 are provided on the rotating plate 70. The multiple outlet holes 9 are arranged one-to-one with the multiple outlet holes 8. The outlet holes 9 can gradually overlap with the outlet holes 8. A drive mechanism 10 for driving the rotating plate 70 to rotate is provided inside the outlet pipe 6.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the user uses the applicator and presses the roller 4, the pressure on the roller 4 triggers the drive mechanism 10. The drive mechanism 10 then starts working, causing the rotating plate 70 to rotate relative to the fixed baffle 7. As the rotating plate 70 rotates, the relative position between the second liquid outlet 9 on it and the first liquid outlet 8 on the baffle 7 changes, gradually transitioning from a completely misaligned state to a completely overlapping state, thus realizing stepless adjustment of the cross-sectional area of ​​the liquid outlet channel. By controlling the liquid flow rate through the operating force applied by the user to the roller 4, the liquid output can be dynamically adjusted according to the user's needs, thereby meeting the differentiated needs of different usage scenarios for liquid supply and improving the flexibility of product use.

[0044] like Figure 2 , Figure 3 and Figure 4 As shown, the drive mechanism 10 includes a threaded rod 101 and a threaded sleeve 102. Both the threaded rod 101 and the threaded sleeve 102 are vertically arranged. A support plate 103 is fixedly connected to the inner wall of the liquid outlet pipe 6. The threaded rod 101 passes through the vertical direction and is slidably connected to the side wall of the support plate 103. A rolling ball 104 is embedded and tumbled at the end of the threaded rod 101 near the ball 4. The rolling ball 104 is attached to and tumbles on the surface of the ball 4. The bottom end of the threaded sleeve 102 is fixedly connected to the top center of the rotating plate 70, and the threaded sleeve 102 is threadedly engaged with the threaded rod 101. A guide block 105 is fixedly connected to the side wall of the threaded rod 101. The guide block 105 passes through the vertical direction and is slidably connected to the side wall of the support plate 103.

[0045] like Figure 2 , Figure 3 and Figure 4 As shown, the drive mechanism 10 also includes a first reset assembly 106 that resets the threaded rod 101. The first reset assembly 106 includes a reset block 1061 and a spring 1062. The reset block 1061 is fixedly connected to the side wall of the guide block 105. The spring 1062 is vertically arranged, and its two ends are fixedly connected to the top side wall of the guide block 105 and the support plate 103, respectively.

[0046] like Figure 2 , Figure 3and Figure 4 As shown, when the ball 4 is pressed, its surface pushes the ball 104, forcing the threaded rod 101 to move linearly along the axial direction. The spring 1062 is compressed. Due to the limiting of the guide block 105, the threaded rod 101 can only slide and cannot rotate. The linear movement of the threaded rod 101 drives the threaded sleeve 102 that it is engaged with to rotate through its thread. The rotation of the threaded sleeve 102 directly drives the rotating plate 70 fixed with it to rotate synchronously, thereby adjusting the alignment area of ​​the liquid outlet hole. When the pressure disappears, the elastic force of the spring 1062 pushes the threaded rod 101 and the ball 104 to reset, driving the entire mechanism to move in the opposite direction, closing or reducing the flow channel. The whole process reduces the difficulty of rotating the rotating plate 70.

[0047] like Figure 2 , Figure 3 and Figure 5 As shown, multiple support blocks 11 slide inside the side wall of the ball bearing seat 3. The multiple support blocks 11 are arranged sequentially along the circumference of the ball bearing seat 3, and the side of the support block 11 near the ball 4 has an arc surface that fits the ball 4. The ball bearing seat 3 is provided with a drive assembly 12 for driving each support block 11 to move. The support block 11 can abut against the surface of the ball 4.

[0048] like Figure 2 , Figure 3 and Figure 5 As shown, when the ball 4 is not in use or needs to be fixed, the user can drive the support block 11 to extend through the drive assembly 12 so that its end abuts against the surface of the ball 4. During storage or transportation, the support block 11 can hold the ball 4 in place to prevent it from rotating accidentally and causing liquid leakage.

[0049] like Figure 2 , Figure 3 and Figure 5 As shown, the drive assembly 12 includes a drive plate 121, a first drive block 122, and a second drive block 123. The drive plate 121 slides vertically on the outer wall of the ball bearing seat 3. The top end of the first drive block 122 is fixedly connected to the drive plate 121. The first drive block 122 passes through the vertical direction and slides to the side wall of the ball bearing seat 3. One end of the second drive block 123 is fixedly connected to the support block 11. The end of the second drive block 123 near the first drive block 122 has an inclined surface, and the second drive block 123 can slide and cooperate with the first drive block 122 through its inclined surface. The end of the second drive block 123 near the first drive block 122 can abut against the first drive block 122. The drive assembly 12 also includes a reset member for resetting the support block 11. The reset member is a second spring 124. The two ends of the second spring 124 are fixedly connected to the support block 11 and the inner wall of the ball bearing seat 3, respectively.

[0050] like Figure 2 , Figure 3 and Figure 5As shown, when not in use, the user moves the drive plate 121 downwards, causing the drive block 122 to move. The inclined surfaces at the ends of the drive block 122 and the drive block 2 123 interact, causing the longitudinal movement of the drive block 122 to drive the drive block 2 123 and the connected support block 11 toward the ball 4 via the inclined surfaces. The spring 2 124 is stretched, causing the support block 11 to extend and finally abut against the ball 4. When in use, the user moves the drive plate 121 upwards. After the drive plate 121 moves the drive block 122 away from the drive block 2 123, the spring 2 124 automatically retracts the support block 11 back to its original position. The whole process reduces the difficulty of moving the support block 11.

[0051] like Figure 2 , Figure 3 and Figure 5 As shown, a stop block 13 is fixedly connected to the side wall of the drive block 122. The stop block 13 slides inside the side wall of the ball seat 3 and can abut against the inner wall of the ball seat 3. The stop block 13 fixed to the side wall of the drive block 122 slides inside the side wall of the ball seat 3, thereby reducing the possibility of the drive plate 121 separating from the ball seat 3.

[0052] like Figure 2 and Figure 6 As shown, multiple slide rods 14 are slidably disposed on the inner side wall of the top of the sealing cover 5 along its top horizontal plane. The multiple slide rods 14 slide along multiple diameter directions on the horizontal cross-section of the ball 4. A block 15 is vertically inserted into the bottom end of the slide rod 14. An elastic cleaning strip 16 for cleaning the surface of the ball 4 is adhered to the side wall of the multiple blocks 15 near the ball 4. The elastic cleaning strip 16 can slide on the surface of the ball 4.

[0053] like Figure 2 and Figure 6 As shown, before the sealing cap 5 is put back on the bottle, multiple sliding rods 14 and cleaning strips gather at the center of the sealing cap 5. Subsequently, when the sealing cap 5 is put back on the bottle, the cleaning strips come into contact with and remain in contact with the ball bearing 4 under the user's pressure. Multiple sliding rods 14 and their elastic cleaning strips 16 at their ends automatically spread out from the center of the ball bearing 4 along multiple diameter directions of its horizontal cross section around the ball bearing 4. The sliding rods 14 can slide horizontally along the inner side wall of the top of the sealing cap 5, so that the cleaning strips can fit tightly against the spherical curved surface of the ball bearing 4, thereby facilitating the scraping and cleaning of the surface of the ball bearing 4, preventing residual liquid from drying, crystallizing or getting dusty, and avoiding clogging of the outlet and contamination of the liquid for the next use. After removing the sealing cap 5, the user can disassemble the cleaning strips for cleaning and replacement, so as to repeatedly clean the ball bearing 4.

[0054] like Figure 2 and Figure 6As shown, multiple guide rods 17 are fixedly installed on the top inner sidewall of the sealing cover 5. The multiple guide rods 17 are arranged one-to-one with multiple slide rods 14. The multiple guide rods 17 are horizontally arranged along multiple diameter directions on the horizontal cross-section of the ball 4. The guide rods 17 pass through in the horizontal direction and slide to the sidewall of the slide rod 14. The guide rods 17 are fixedly arranged along the diameter direction of the horizontal cross-section of the ball 4, so that all slide rods 14 move radially along the ball 4, which improves the stability of the movement of the slide rods 14.

[0055] like Figure 2 and Figure 6 As shown, a return spring 18 is sleeved on the guide rod 17. The two ends of the return spring 18 are fixedly set on the slide rod 14 and the inner side wall of the top of the sealing cover 5, respectively. When the cover is closed, the slide rod 14 moves to spread around the ball 4, and the return spring 18 is stretched. Then, when the cover is removed, the elastic force of the return spring 18 can pull the slide rod 14 back to the center position of the sealing cover 5, so that the cleaning strip can clean the surface of the ball 4 again when the cover is closed next time.

[0056] like Figure 2 , Figure 6 and Figure 7 As shown, a plug-in block 19 slides vertically at the top end of the slide rod 14. A slot for the plug-in block 19 to be inserted is provided on the inner side wall of the top of the sealing cover 5 at the farthest position of the sliding path of the slide rod 14. A push spring 20 is provided inside the top side wall of the slide rod 14. The push spring 20 is set vertically, and the two ends of the push spring 20 abut against the plug-in block 19 and the inner wall of the slide rod 14, respectively.

[0057] like Figure 2 , Figure 6 and Figure 7 As shown, when the sealing cover 5 is fully closed, the return spring 18 is in a stretched state. Therefore, the slide rod 14 and the cleaning strip tend to move towards the center of the ball 4 under the elastic pull of the return spring 18. At the same time, due to the curved surface of the ball 4, the slide rod 14 and the cleaning strip also tend to push the ball 4 downward, causing the sealing cover 5 to fall off and separate from the ball 4. Therefore, when the sealing cover 5 is fully closed, the slide rod 14 and the cleaning strip move to the edge of the ball 4. At this time, the insertion block 19 is inserted into the slot on the sealing cover 5 under the elastic force of the push spring 20, so that the slide rod 14 always stays at the edge of the ball 4, greatly reducing the force of the slide rod 14 and the cleaning strip on the ball 4, and reducing the possibility of the sealing cover 5 separating from the ball 4 and the outer shell 2.

[0058] like Figure 2 , Figure 6 and Figure 7As shown, a ring-shaped push plate 21 slides vertically on the outer side wall of the top of the sealing cover 5. Multiple push blocks 22 are fixedly connected to the bottom side wall of the push plate 21. The push blocks 22 slide vertically inside the side wall of the sealing cover 5, and the multiple push blocks 22 are arranged in a one-to-one correspondence with multiple plug-in blocks 19. The bottom end of the push block 22 can abut against the plug-in block 19.

[0059] like Figure 2 , Figure 6 and Figure 7 As shown, the side wall of the sealing cover 5 is provided with a second reset assembly 23 that resets the push plate 21. The second reset assembly 23 includes a second reset block 231 and a third spring 232. The second reset block 231 is fixedly connected to the side wall of the push plate 21. The third spring 232 is vertically arranged, and its two ends are fixedly connected to the second reset block 231 and the side wall of the sealing cover 5, respectively.

[0060] like Figure 2 , Figure 6 and Figure 7 As shown, when the user removes the sealing cover 5, the user can press the push plate 21 into the sealing cover 5, the spring 232 is compressed, the push plate 21 drives the push block 22 to move, the push block 22 then contacts the plug block 19 and pushes the plug block 19 out of the slot. Subsequently, the slide rod 14 can be reset to the center position of the sealing cover 5 under the elastic force of the reset spring 18, so as to clean the ball 4 again. When the user releases the force on the push plate 21, the push plate 21 and the push block 22 can be reset under the action of the spring 232, so as to push the plug block 19 to move again.

[0061] The implementation principle of this application embodiment is as follows: When the user uses the applicator and presses the roller ball 4, the pressure on the roller ball 4 can trigger the drive mechanism 10. The drive mechanism 10 then starts to work, causing the rotating plate to rotate relative to the fixed baffle 7. As the rotating plate rotates, the relative position between the second liquid outlet 9 on it and the first liquid outlet 8 on the baffle 7 changes. The two gradually transition from a completely misaligned state to a completely overlapping state, realizing stepless adjustment of the cross-sectional area of ​​the liquid outlet channel. The liquid flow rate is controlled by the operating force applied by the user on the roller ball 4, so that the liquid output can be dynamically adapted and adjusted according to the user's needs, thereby meeting the differentiated needs of liquid supply in different usage scenarios and improving the flexibility of product use.

[0062] 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.
