[0041] The following will be combined with the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described in this application are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the following drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0043] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0044] Embodiment: As shown in Figure 1-19, a press-type cosmetic pen includes a pen tip assembly 100, a pen body assembly 200, a discharge assembly 300 and a drive assembly 400. The pen tip assembly 100 includes a sleeve 110, and the discharge assembly 300 includes a carrier 310 and a screw 320. The sleeve 110 is rotatably installed in the pen body assembly 200, and the drive assembly 400 is installed in the pen body assembly 200. The carrier 310 is screwed to the screw 320, and the screw 320 is screwed to the drive assembly 400. The sleeve 110 can drive the carrier 310 to rotate synchronously, thereby making the carrier 310 run along the axial direction of the screw 320 to retract into the inside of the screw 320. The drive assembly 400 can drive the screw 320 to move along the axial direction of the sleeve 110 toward the free end of the sleeve 110.

[0045] Optionally, the carrier 310 is inserted into the screw 320 and the two are screwed together, and the screw 320 is installed in the drive assembly 400 and the two are screwed together. The cosmetic material 330 is stored in the carrier 310, and the cosmetic material 330 can be lipstick, eye shadow, lip gloss, lip balm, eyeliner paste, sunscreen stick, body fragrance or deodorant stick, etc. When the drive assembly 400 drives the screw 320 to move, the screw 320 carries the carrier 310 to run synchronously along the axial direction of the sleeve 110 so that the cosmetic material 330 extends out of the sleeve 110 for user use. It should be noted that the screw 320 and the carrier 310 remain relatively stationary and do not rotate relative to each other. In this scenario, the screw 320 and the carrier 310 can be regarded as a whole of the discharging assembly 300 and participate in the mechanical structure coordination inside the entire push-type cosmetic pen. Under the action of the sleeve 110, the direction in which the material carrier 310 moves is opposite to the direction in which the material carrier 310 moves under the action of the screw 320. Optionally, the pen tip assembly 100 further includes a pen cap 120, which is pluggable and sleeved on the sleeve 110.

[0046] As shown in Figures 1 and 2, the free end of the sleeve 110 is an open end and is located outside the pen body assembly 200. The rear end of the sleeve 110 is located inside the pen body assembly 200 and the rear end of the sleeve 110 is close to the driving assembly 400. When the cosmetic pen is assembled, as shown in Figure 13, the material carrier 310 is located inside the sleeve 110 and is close to the free end of the sleeve 110. The cosmetic material 330, such as a lipstick stick, is pressed through the open end of the sleeve 110. The filling operation is completed by inserting the material into the sleeve 110. Then, the operator or the manipulator rotates the sleeve 110, and the sleeve 110 drives the material carrier 310 to rotate synchronously. Since the material carrier 310 is screwed to the screw 320, the material carrier 310 can move axially relative to the screw 320 while rotating, until it reaches the state shown in Figure 16, that is, the material carrier 310 is retracted to the maximum extent inside the screw 320. Finally, the pen cap 120 is covered to complete the cosmetic pen filling process. In this application, the material carrier is located at the free end of the sleeve, so it is convenient to fill the cosmetic material from the front end of the cosmetic pen into the assembled cosmetic pen, and loading is very convenient. After loading, by rotating the sleeve and utilizing the screw connection between the material carrier and the screw, the material carrier is retracted into the screw, and the cosmetic material is retracted into the sleeve at the same time, which is very convenient to operate.

[0047] When the push-type makeup brush filled with cosmetic or skin care products is used, the screw 320 drives the carrier 310 to move synchronously along the axial direction of the sleeve 110 under the action of the drive assembly 400, so that the cosmetic material is extended from the sleeve for easy use by the user. In this application, the user can operate the drive assembly with one hand to complete the discharging of the makeup brush, making it more convenient to use. In this application, the screw is screwed to the carrier and the drive assembly respectively, which can complete the loading and discharging process of the cosmetic material, thereby simplifying the structure of the makeup brush and reducing the development and manufacturing costs of the makeup brush.

[0048] As shown in Figure 1 , sleeve 110 is axially fixed and circumferentially movable within pen body assembly 200, and sleeve 110 is capable of driving material carrier 310 toward drive assembly 400. In one possible embodiment, sleeve 110 is axially fixed and circumferentially movable within pen body assembly 200 as follows: a first circumferentially arranged retaining ring is provided on the outer circumferential wall of sleeve 110, and a second circumferentially arranged retaining ring is provided on the inner circumferential wall of pen body assembly 200. The first and second retaining rings fit together, allowing sleeve 110 to rotate relative to pen body assembly 200, but preventing sleeve 110 from axially moving relative to pen body assembly 200.

[0049] In another possible embodiment, the sleeve 110 is axially fixed and circumferentially movably installed inside the pen body assembly 200. The structure is as follows: the outer circumferential wall of the sleeve 110 is provided with a first retaining ring arranged along the circumferential direction, and the inner circumferential wall of the pen body assembly 200 is provided with a groove for engaging with the first retaining ring, or the inner circumferential wall of the pen body assembly 200 is provided with a first retaining ring arranged along the circumferential direction, and the outer circumferential wall of the sleeve 110 is provided with a groove for engaging with the first retaining ring. The sleeve 110 can rotate relative to the pen body assembly 200 through the cooperation between the first retaining ring and the groove, but the sleeve 110 cannot move axially relative to the pen body assembly 200.

[0050] Optionally, the sleeve 110 is unidirectionally mounted within the body assembly 200. That is, the sleeve 110 can only rotate clockwise or counterclockwise relative to the body assembly 200, thereby ensuring that the carrier 310 can only move toward the drive assembly 400. Only after the cosmetic material 330 is inserted can the sleeve 110 be rotated to retract it. During use, the cosmetic material 330 cannot be extended or retracted by rotating the sleeve 110, and can only be discharged by operating the drive assembly 400. This effectively prevents accidental discharge of cosmetic material, which could cause contamination and waste.

[0051] As shown in FIG1 , the pen body assembly 200 includes a penholder 210 and a coupling 220 that are fixedly connected. The coupling 220 is fixedly mounted within the penholder 210 and protrudes from the rear end of the penholder 210. The drive assembly 400 is mounted within the coupling 220, and the screw 320 is mounted within the drive assembly 400. As shown in FIG5 and FIG6 , the sleeve 110 is provided with elastic teeth 111, which are provided with a first inclined surface 112 and a first straight surface 113. As shown in FIG14 , the inner circumferential wall of the penholder 210 is provided with serrations 211, which are provided with a second inclined surface 212 and a second straight surface 213. The first inclined surface 112 is capable of sliding on the second inclined surface 212, and the first straight surface 113 is stopped by the second straight surface 213.

[0052] As shown in FIG5 , in one possible embodiment, a mounting groove is provided on the sleeve 110, and an elastic tooth 111 is provided in the mounting groove. The first end of the elastic tooth 111 is fixedly connected to the sleeve 110, and the second end of the elastic tooth 111 is a free end. Optionally, except for the first end fixedly connected to the sleeve 110, the rest of the elastic tooth 111 is disconnected from the sleeve 110, so that the elastic tooth 111 has a certain degree of elasticity. As shown in FIG6 , a first straight surface 113 is located at the second end of the elastic tooth 111, and a first inclined surface 112 is located on the outer surface of the elastic tooth 111. Optionally, two elastic teeth 111 are provided on the sleeve 110, and the two elastic teeth 111 are symmetrically arranged along the central axis of the sleeve 110. The inner circumferential wall of the pen body 210 is provided with a plurality of serrations 211 connected in sequence. This ensures that the force on the sleeve 110 is balanced during rotation, thereby improving the user's operating comfort.

[0053] As shown in Figures 13 and 14, when the sleeve 110 is installed on the pen holder 210, the first straight surface 113 and the second straight surface 213 abut against each other, and the first inclined surface 112 and the second inclined surface 212 are in contact with each other. When the user rotates the sleeve 110 clockwise, the elasticity of the elastic teeth 111 causes the first inclined surface 112 to slide smoothly from the second inclined surface 212 of the previous sawtooth 211 to the second inclined surface 212 of the next sawtooth 211, and the first straight surface 113 and the second straight surface 213 of the next sawtooth 211 again abut against each other. Because the first straight surface 113 and the second straight surface 213 abut against each other, the user cannot rotate the sleeve 110 counterclockwise, preventing the user from manually rotating the sleeve to rotate the cosmetic material back during use, thereby ensuring the one-way discharge function of the cosmetic material.

[0054] In another possible embodiment, the outer circumferential wall of the sleeve 110 is provided with a plurality of elastic teeth 111 connected in sequence, and the inner circumferential wall of the pen body 210 is provided with a plurality of serrations 211 connected in sequence. The unidirectional rotation function of the sleeve 110 can also be achieved by utilizing the plurality of elastic teeth 111 and the serrations 211 to cooperate with each other.

[0055] As shown in Figure 7, the material carrier 310 includes a material carrier 311 and a connecting rod 312 fixed to the material carrier 311. The material carrier 311 is circumferentially fixed and axially movably installed in the sleeve 110, and the connecting rod 312 is screwed to the screw 320. The structure of the material carrier 311 being circumferentially fixed and axially movably installed in the sleeve 110 is as follows: the outer circumferential wall of the material carrier 311 forms a non-cylindrical structure, and the shape of the inner circumferential wall of the sleeve 110 is the same as the shape of the outer circumferential wall of the material carrier 311. The non-cylindrical structure includes a polyhedron, a prism or other special-shaped structure, so that when the sleeve 110 rotates, it can rotate synchronously with the material carrier 311. Of course, the outer circumferential wall of the material carrier 311 and the inner circumferential wall of the sleeve 110 can also be designed as a cylindrical structure, and the two can be rotated synchronously by ribs or grooves.

[0056] As shown in Figures 7, 8 and 15, the outer wall of the connecting rod 312 is provided with a first external thread 313, a cavity 321 is provided in the screw 320, the inner wall of the screw 320 is provided with a first internal thread 322, the outer wall of the screw 320 is provided with a second external thread 323, the connecting rod 312 is inserted into the cavity 321, and the first external thread 313 and the first internal thread 322 cooperate with each other. As shown in Figures 13 and 15, a first internal thread 322 is provided at one end of the screw 320 close to the sleeve 110. At the beginning, the end of the connecting rod 312 is inserted into the cavity 321 of the screw 320, and the loading barrel 311 is close to the open end of the sleeve 110. When the filling is completed, that is, the cosmetic material 330, such as a lipstick stick, is inserted into the loading barrel 311, the sleeve 110 is rotated, and the sleeve 110 drives the loading part 310 to rotate. At the same time, under the action of the first external thread 313 and the first internal thread 322, the connecting rod 312 runs toward the depth of the cavity 321 until the connecting rod 312 is completely entered into the cavity 321, and the cosmetic material 330 is completely retracted into the sleeve 110.

[0057] As shown in Figures 16 and 17 , when the connecting rod 312 is fully retracted into the screw 320, the screw 320 abuts against the bottom of the material carrier 311. Thus, when the screw 320 moves away from the drive assembly 400 under the action of the drive assembly 400, it can drive the material carrier 310 to move synchronously to complete the material discharge operation. Furthermore, during use, the cosmetic material 330 cannot be retracted into the sleeve 110 by rotating the sleeve 110, thus achieving a one-way material discharge operation.

[0058] The driving assembly 400 can only drive the discharging assembly 300 to move in a direction away from the driving assembly 400. As shown in Figures 1-3, the driving assembly 400 includes a button 410, a ratchet 420, a ratchet seat 430, a ratchet 440, an elastic member 450 and a rotating member 460. The ratchet 420 is fixedly installed in the button 410, and the ratchet 420 and the ratchet 440 are movably installed in the ratchet seat 430. The ratchet 420 and the ratchet 440 are engaged with each other. The rotating member 460 is sleeved on the screw 320 and rotates. The rotating member 460 is screwed to the screw rod 320, and the rotating member 460 abuts against the pen body assembly 200. As shown in FIG17 , the rotating member 460 is installed inside the connecting member 220, and the rotating member 460 abuts against the connecting member 220. As shown in FIG1 , an elastic member 450 is provided between the rotating member 460 and the ratchet 440. The ratchet 420 can drive the ratchet 440 to rotate, and the ratchet 440 can drive the rotating member 460 to rotate, and then the rotating member 460 drives the screw rod 320 to move in a direction away from the button 410.

[0059] As shown in Figure 1, the connecting member 220 is fixedly installed inside the pen barrel 210, and the connecting member 220 protrudes from the rear end of the pen barrel 210, the ratchet seat 430 and the rotating member 460 are installed in the connecting member 220, the first end of the elastic member 450 abuts against the rotating member 460, the second end of the elastic member 450 abuts against the ratchet 440, and the button 410 protrudes from the connecting member 220. During use, the user presses the button 410, and the button 410 drives the ratchet 420 and the ratchet 440 to move synchronously toward the rotating member 460, the elastic member 450 is compressed, and the button 410 drives the ratchet 440 to rotate through the ratchet 420, and the ratchet 440 drives the rotating member 460 to rotate, and the rotating member 460 drives the screw 320 and the carrier 310 to run synchronously along the axial direction of the sleeve 110 to realize a one-way discharging operation. The user presses the button 410 once, and the screw 320 will drive a small amount of cosmetic material 330 to extend for the user to use, thereby facilitating the control of the discharge amount and preventing material pollution and waste. When the user releases the button 410, under the action of the elastic member 450, the button 410, the ratchet 420 and the ratchet 440 reset and wait for the next press.

[0060] As shown in FIG9 , the ratchet 420 is provided with a first latching tooth 421 . As shown in FIG10 , the ratchet 440 is provided with a second latching tooth 441 and a first pawl 442 . As shown in FIG4 , FIG11 , and FIG15 , the rotating member 460 is provided with a second pawl 461 , and the inner circumferential wall of the rotating member 460 is provided with a second internal thread 462 . The first latching tooth 421 and the second latching tooth 441 are meshed with each other. A gap is provided between two adjacent first pawls 442 , and the second pawl 461 is inserted into the gap to achieve synchronous rotation of the rotating member 460 and the ratchet 440 . The rotating member 460 is sleeved on the screw 320 , and the second internal thread 462 on the rotating member 460 cooperates with the second external thread 323 on the screw 320 . In this application, the rotating member 460 is used to drive the screw 320 . During operation, the rotating member 460 only needs to rotate, rather than moving along the axial direction of the screw 320 , thereby simplifying the structure of the rotating member and the screw.

[0061] When the bottle 310 is in the process of being wound, the end portion of the bottle 310 is tightened and the bottle 310 is tightened, so that the bottle 310 can be tightened and the bottle 310 can be tightened.

[0062] During use, the user presses the button 410 at the end of the cosmetic brush. The button 410, along with the ratchet 420 and ratchet wheel 440, moves synchronously toward the rotating member 460, compressing the elastic member 450. The button 410, via the ratchet 420, drives the ratchet wheel 440 to rotate. The ratchet 440 then drives the rotating member 460 to rotate. The rotating member 460 then drives the screw 320 and the material carrier 310 to move synchronously along the axial direction of the sleeve 110, thereby achieving a one-way dispensing operation. The user presses the button 410 once, and the screw 320 forces a small amount of cosmetic material 330 to be dispensed for the user. When the user releases the button 410, the button 410, ratchet 420, and ratchet wheel 440 return to their original position under the action of the elastic member 450, ready for the next press. Figure 18 shows the button 410 being pressed, and Figure 19 shows the cosmetic material being used up. At this point, the material carrier 310 and screw 320 synchronously move into the sleeve 110.
