Detailed Implementation

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such uses of the terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0036] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0037] Example: Figure 1-17 As shown, a cosmetic applicator includes a pen tip assembly 10, a bottle 20, a pen body assembly 30, a rotating component 40, a screw 50, and a control component. The pen tip assembly 10 is mounted on the first end of the bottle 20. The first end of the rotating component 40 is connected to the second end of the bottle 20, and the second end of the rotating component 40 is connected to the pen body assembly 30. A piston 21 is provided inside the bottle 20. The screw 50 and the control component are mounted in the pen body assembly 30. The control component is connected to the screw 50 and can drive the screw 50 to move toward the pen tip assembly 10. The rotating component 40 can drive the screw 50 to rotate and cause the screw 50 to disengage from the control component and move away from the pen tip assembly 10.

[0038] like Figure 1 As shown, this cosmetic applicator consists of, from top to bottom, a pen tip assembly 10, a product bottle 20, a rotating component 40, and a pen body assembly 30. Figure 4 As shown, a piston 21 is provided in the bottle 20. The piston 21 is airtightly fitted to the inner wall of the bottle 20. Therefore, the bottle 20 and the piston 21 form a sealed storage chamber for storing cosmetic materials. The pen tip assembly 10 is connected to the bottle 20. The rotating part 40 is located between the bottle 20 and the pen body assembly 30. The screw 50 and the control assembly are installed in the pen body assembly 30, and the upper end of the screw 50 abuts against the piston 21.

[0039] In use, the user presses the control component, causing the screw 50 to drive the piston 21 towards the pen tip assembly 10. The piston pushes the material in the bottle 20 towards the pen tip assembly 10. When the material in the bottle 20 is used up (e.g. Figure 3(As shown) or when it is necessary to change to another type of bottle 20, the user rotates the bottle 20, which drives the rotating part 40 to rotate. The rotating part 40 drives the screw 50 to rotate at a certain angle. After the screw 50 is disengaged from the control component, it falls to the bottom of the pen body assembly 30. Then, the bottle 20 and pen tip assembly 10 are removed from the rotating part 40. The new bottle 20 and pen tip assembly 10 are then installed on the rotating part 40. Finally, the rotating part 40 is rotated in the opposite direction to restore the screw 50 to its initial state, thus completing the bottle replacement.

[0040] Therefore, during the use of this cosmetic applicator, when the product in the bottle is exhausted, the bottle and pen tip assembly can be directly replaced, and other parts of the container can be reused, thereby reducing the manufacturing cost of the container, alleviating the burden on consumers, and reducing resource waste. The set of this container can be equipped with bottles of various products, and different types of bottles can be replaced during use to meet diverse usage needs. In this application, the rotating part is installed between the bottle and the pen body assembly, resulting in a compact overall structure. Moreover, the screw can be retracted during the bottle replacement process, making it convenient to operate.

[0041] Optionally, the screw 50 is circumferentially fixed and axially movable within the rotating member 40. Circumferentially fixed means that when the rotating member 40 rotates, it drives the screw 50 to rotate synchronously, and vice versa; that is, the circumferential movement of the screw 50 and the rotating member 40 is consistent. Axially movable means that the screw 50 can move axially relative to the rotating member 40, such as... Figure 3 As shown, the screw 50 can move upward relative to the rotating member 40 to extrude the material, or as... Figure 4-5 As shown, the screw 50 can be reset by moving downward relative to the rotating member 40.

[0042] like Figure 16 As shown, the rotating component 40 has a mounting hole 43, and the screw 50 passes through the mounting hole 43. The cross-sectional shape of the screw 50 is the same as the cross-sectional shape of the mounting hole 43, but the cross-sectional shape is non-circular. Figure 2As shown, the cross-sections of the screw 50 and the mounting hole 43 refer to the cross-sections along the radial direction. Both have the same cross-sectional shape. For the rotating part 40, the cross-section refers to the cross-section of the inner wall of the part where the rotating part 40 and the screw 50 are in contact. The area of ​​the cross-section of the mounting hole 43 can be slightly larger than the area of ​​the cross-section of the screw 50. That is, the surface of the rotating part 40 is in contact with the outer surface of the screw 50, and the shape of the cross-section is not circular. In this way, when the rotating part 40 rotates, it can rotate the screw 50 synchronously. Theoretically, as long as the part where the screw 50 and the rotating part 40 are in contact is not a cylindrical structure, synchronous rotation of the two can be achieved. In actual processing, a suitable structure needs to be selected based on factors such as processing and assembly costs and difficulty. Optionally, the shape of the cross-section can be oblong, polygonal, or other irregular structures.

[0043] like Figure 2 and Figure 6 As shown, the cross-sections of the screw 50 and the mounting hole 43 are oblong or regular polygons. Designing the cross-sections of the screw 50 and the mounting hole 43 as oblong or regular polygons facilitates the machining and installation of the rotating parts and the screw.

[0044] In another embodiment, the rotating component 40 has a mounting hole 43, and the screw 50 passes through the mounting hole 43. The inner wall of the rotating component 40 extends radially inward to form a slider, and the screw 50 has a groove in the axial direction. Alternatively, the screw 50 extends radially outward to form a slider, and the inner wall of the rotating component 40 has a groove in the axial direction. The slider is inserted into the groove and can slide along the groove. That is, the rotating component 40 and the screw 50 interfere with each other through the slider and the groove, so that they rotate synchronously, but the screw 50 can move axially (up and down) relative to the rotating component 40. Or, the inner wall of the rotating component 40 extends toward the mounting hole 43 to form two parallel stops, which are respectively set on the front and rear sides of the screw 50. In this way, when the rotating component 40 rotates, it can drive the screw 50 to rotate synchronously. In the above structure, the structure of the mounting hole 43 and the cross-section of the screw 50 is not limited and can be various common structures such as circles, ovals, and polygons.

[0045] like Figure 1 , Figure 3-6 and Figure 9-10 As shown, the pen body assembly 30 includes a pen body 31 and a tail plug 32 mounted on the pen body 31. The second end of the rotating member 40 is rotatably connected to the pen body 31, and the maximum angle at which the rotating member 40 can rotate relative to the pen body 31 is 90°.

[0046] like Figure 13-14As shown, the pen body 31 has a first open end and a second open end. The tail plug 32 is fitted into the second open end. The side wall of the pen body 31 is provided with a mounting groove 33. A first limiting block 36 and a second limiting block 37 are fixedly provided on the first open end. A third limiting block extending radially inward is fixedly provided on the rotating component 40. The third limiting block can rotate between the first limiting block 36 and the second limiting block 37. When the third limiting block moves from the first limiting block 36 to the second limiting block 37, the rotating component 40 rotates exactly 90°, and vice versa, causing the screw 50 to disengage from the control component or reconnect to the control component, such as... Figure 3-5 As shown, the rotating part 40 is screwed to the first open end of the pen body. Optionally, the first limiting part 36 and the second limiting part 37 are arc-shaped and are symmetrically arranged along the central axis of the pen body. Therefore, there are two gaps between the first limiting part 36 and the second limiting part 37. The rotating part 40 is provided with two third limiting parts, which are located in the two gaps respectively. The two third limiting parts abut against the first limiting part 36 and the second limiting part 37 respectively. The starting position of the rotating part 40 is when one of the third limiting parts abuts against the end of the first limiting part 36 facing the outside of the paper. At this time, the screw 50 is engaged with the control component, and the cosmetic applicator is in the ready-to-use state. Then, the rotating part 40 is rotated clockwise so that the third limiting part abuts against the end of the second limiting part 37 facing the outside of the paper. That is, the rotating part 40 has completed a 90° rotation. At this time, the rotating part 40 cannot be rotated clockwise. The screw is disengaged from the control component and falls down. The cosmetic applicator is in the material changing state. Optionally, a protrusion 38 is provided on the pen body 31 near the first limiting member 36 and the second limiting member 37. When the rotating member 40 is about to rotate to the end point, it needs to pass over this protrusion 38, thereby bringing a good user experience.

[0047] like Figure 3-5 As shown, the first end of the rotating component 40 is screwed to the bottle 20, or the first end of the rotating component 40 is engaged with the bottle 20. Figure 15-16 As shown, the rotating component 40 includes a first sleeve 41 and a second sleeve 42 that are fixedly connected and coaxially arranged. The first sleeve 41 has an external thread that is screwed to the bottle 20, and the second sleeve 42 has an internal thread that is screwed to the pen body 31. When the bottle 20 needs to be replaced, the bottle 20 is rotated clockwise, and the bottle 20 drives the rotating component 40 to rotate synchronously. After the rotating component has rotated 90°, the screw 50 disengages from the control component and falls to the bottom of the pen body 31. At this time, the rotating component 40 is blocked by the first limit block 36 and the second limit block 37 on the pen body 31 and cannot rotate clockwise further. Continuing to rotate the bottle 20 will unscrew the bottle 20 from the rotating component 40, thus separating the bottle 20 from the rotating component 40. Therefore, with this rotating component structure, the user only needs to rotate the bottle to complete the screw retraction and bottle disassembly operations, eliminating the step of separately operating the screw retraction, making the operation convenient, fast, and smooth.

[0048] Optionally, the first sleeve 41 is engaged and fixed with the material bottle 20, and the second sleeve 42 is provided with an internal thread and screwed to the pen body 31. When the material bottle 20 needs to be replaced, the material bottle 20 is rotated clockwise, and the material bottle 20 drives the rotating part 40 to rotate synchronously. After the rotating part has rotated 90°, the screw 50 is disengaged from the control component, and the screw 50 falls to the bottom of the pen body 31. Then the material bottle 20 can be pulled out from the rotating part 40, thereby increasing the versatility of the cosmetic applicator.

[0049] like Figure 3 , Figure 6-7 As shown, the pen tip assembly 10 includes a water inlet core 11, a water inlet core seat 12, a pen tip inner seat 13, and a pen tip outer cover 14. The pen tip inner seat 13 is connected to the first end of the material bottle 20. The water inlet core 11 is fixedly installed on the pen tip inner seat 13, and the water inlet core seat 12 is fixedly sleeved on the outside of the pen tip inner seat 13. The pen tip outer cover 14 is detachably fitted onto the water inlet core seat 12. The pen tip inner seat 13 is screwed to the material bottle 20, and the pen tip inner seat 13 is inserted into the water inlet core 11. The pen tip inner seat 13 has a material channel, so that the material in the pen body 31 can flow into the water inlet core 11 through the pen tip inner seat 13 for the user to use.

[0050] like Figure 3-6 As shown, the control assembly includes a button 60, a first screw sleeve 70, and a second screw sleeve 80. The first screw sleeve 70 has a first hook 72, and the second screw sleeve 80 has a second hook 81. The button 60 is mounted on the pen body assembly 30. The first screw sleeve 70 is axially movably mounted within the pen body assembly 30, and the second screw sleeve 80 is fixedly mounted within the pen body assembly 30. The screw 50 includes a first connecting section 51 and a second connecting section 52. The second connecting section 52 has serrations 54. The second connecting section 52 is inserted into the first screw sleeve 70 and the second screw sleeve 80, and the serrations 54 can engage with the first hook 72 and the second hook 81. A first elastic element 34 is provided between the first screw sleeve 70 and the pen body assembly 30, and a second elastic element 35 is provided between the second screw sleeve 80 and the screw 50. When the button 60 is subjected to force, it presses the first screw sleeve 70, causing the first screw sleeve 70 and the screw 50 to move along the axial direction of the pen body assembly 30. Figure 6 and Figure 9-10 As shown, button 60 is installed in the mounting slot 33 of the pen body, and button 60 has a first inclined surface 61, as... Figure 3 As shown, the first screw sleeve 70 is installed inside the pen body 31, and the first screw sleeve 70 is provided with a second inclined surface 71. The second screw sleeve 80 is located below the first screw sleeve 70, as shown. Figure 17 As shown, the screw 50 includes a first connecting section 51, a second connecting section 52, and a boss 53 that are fixedly connected in sequence. The outer side wall of the first connecting section 51 is smooth, and the front and rear side walls of the second connecting section 52 are smooth, while the left and right side walls are provided with a plurality of serrations 54, such as... Figure 3 and Figure 4 As shown, the rotating component 40 is always fitted onto the first connecting section 51, therefore the length of the first connecting section 51 is greater than or equal to the maximum distance the screw 50 rises. The first elastic component 34 is installed between the pen body 31 and the first screw sleeve 70, and the second elastic component 35 is installed between the second screw sleeve 80 and the boss 53 of the screw. When the screw 50 is in the initial state (e.g. Figure 4 (As shown) This is the working state, with the saw teeth 54 engaging with the first claw 72 and the second claw 81 respectively.

[0051] In use, the user presses button 60. The first inclined surface 61 on button 60 acts on the second inclined surface 71 of the first screw sleeve, pushing the first screw sleeve 70 upward. Since the serration 54 engages with the first hook 72, the first screw sleeve 70 drives the screw 50 to rise synchronously. The first elastic element 34 is compressed, and the screw 50 slides upward relative to the second screw sleeve 80 by one serration before re-engaging with the second screw sleeve 80. The second elastic element 35 is compressed, and the screw 50 pushes the piston 21 upward, pushing the material in the bottle 20 towards the pen tip assembly 10. After releasing the button, the first elastic element 34 drives the first screw sleeve 70 downward to return to its original position. That is, after pressing button 60 once, only the screw 50 moves one serration distance towards the pen tip assembly 10. The amount of material dispensed with each press of the button is small and fixed, so the amount of material dispensed from the container can be precisely controlled.

[0052] When the material in bottle 20 is used up (e.g.) Figure 3 As shown, when the piston 21 rises to its highest position or when the bottle needs to be replaced midway, the user rotates the bottle 20. First, the bottle 20 drives the rotating component 40 to rotate. Since the contact surface between the rotating component and the first connecting section of the screw is non-cylindrical, the rotating component 40 can drive the screw 50 to rotate. When the screw 50 rotates 90°, the screw 50 is blocked by the first limiting block 36 and the second limiting block 37 on the pen body 31 and cannot rotate further. At this time, the smooth surface of the second connecting section 52 of the screw faces the first hook 72 and the second hook. Claw 81, so the screw disengages from the first screw sleeve 70 and the second screw sleeve 80, and moves down to the bottom of the pen body 31 under the action of the second elastic element 35. Then the material bottle 20 continues to rotate. Since the material bottle and the rotating element 40 are screwed together, the material bottle can be unscrewed from the rotating element 40 and replaced with a new material bottle 20. Rotate the material bottle 20 in the opposite direction until the material bottle is screwed tightly to the rotating element 40. Continue to rotate the material bottle 20. After the material bottle drives the rotating element 40 to rotate 90° relative to the pen body 31, the screw 50 returns to the working state.

[0053] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
