[0028] Embodiment 1

[0029] As shown in Figures 1-4 Embodiment 1 discloses a material discharging assembly 100 for pushing the carrier assembly 21 of a cosmetic pencil 200 to move.

[0030] The material discharging assembly 100 comprises a discharging piece 11 and a linkage piece 12, one end of the linkage piece 12 is connectable with the carrier assembly 21, the other end of the linkage piece 12 is used to abut against the discharging piece 11, the linkage piece 12 is provided with a claw 121 extending towards the discharging piece 11, the discharging piece 11 is provided with an abutment groove 112 matched with the claw 121, the abutment groove 112 is arranged around the circumferential side of the discharging piece 11, the claw 121 can be embedded in the abutment groove 112 and slide along the arrangement direction of the abutment groove 112, and the discharging piece 11 can move along the moving direction of the carrier assembly 21 and drive the linkage piece 12 to rotate in the abutment groove 112.

[0031] Therefore, in the embodiment, when the user applies pressure to the material discharging assembly 100 with one hand, the discharging piece 11 can move along the moving direction of the material carrying assembly 21, and as the discharging piece 11 moves, the pawl 121 embedded in the abutting groove 112 of the discharging piece 11 can drive the linkage 12 to slide in the abutting groove 112, i.e., rotate along the circumferential direction of the discharging piece 11, so that the material carrying assembly 21 connected with the linkage 12 can move along its moving direction to realize the extension of the material and provide the user with the material. With the above structure, the conversion from linear pressing action to rotary discharging action is realized, so that one-handed operation is possible, and the convenience and efficiency of user operation are improved.

[0032] As shown in Figure 4 The end of the pawl 121 towards the discharging piece 11 is provided with a slope 1211, the slope 1211 and the moving direction of the material carrying assembly 21 form an included angle greater than zero, the slope 1211 and the surface of the abutting groove 112 are in abutment, and the linkage 12 can slide in the abutting groove 112 through the slope 1211. Specifically, when the user applies pressure to the discharging piece 11, the discharging piece 11 can move along the moving direction of the material carrying assembly 21, so that the slope 1211 of the pawl 121 slides in the abutting groove 112, and due to the included angle between the slope 1211 and the moving direction, the sliding motion of the pawl 121 can not only move the linkage 12 in the abutting groove 112, but also rotate it circumferentially around the discharging piece 11.

[0033] Therefore, the design of the slope 1211 enables the linkage 12 to push the material carrying assembly 21 to move at a certain angle when it slides in the abutting groove 112, so as to accurately control the discharging amount and ensure that the material can be accurately pushed to the required position according to the user's needs. Moreover, the abutment design of the slope 1211 and the abutting groove 112, as well as the cooperation of the linkage 12 and the discharging piece 11, enhances the structural stability of the material discharging assembly 100 and reduces the possibility of vibration or shaking during the pushing of the material carrying assembly 21 to discharge.

[0034] Preferably, the plurality of claws 121 are arranged in sequence along the circumferential direction of the linkage 12, and the inclined surfaces 1211 of the claws 121 are located on the same side of the claws 121, specifically, in the radial direction perpendicular to the moving direction of the material carrying assembly 21, the claws 121 have left and right sides towards one end of the discharging member 11, and the inclined surfaces 1211 are located on the same side of the claws 121, i.e. on the left side or the right side, and towards the same side. The purpose of this arrangement is that the discharging member 11 can push the linkage 12 in one direction, so that the sliding direction of each abutting groove 112 relative to the inclined surface 1211 is consistent, preventing the linkage 12 from rotating in the opposite direction, and maintaining the stability of the movement track of the material carrying assembly 21. In addition, the arrangement of the plurality of claws 121 ensures that the force transmitted by the discharging member 11 to the linkage 12 can be evenly distributed to each claw 121 of the linkage 12, reducing local stress and improving the durability of the linkage 12.

[0035] As shown in Figure 3 The linkage 12 further includes a through pipe 122 and a connecting claw 123. The through pipe 122 is used for the material carrying assembly 21 to pass through, the claws 121 are arranged on the outer wall surface of the through pipe 122 and extend towards one side of the discharging member 11, and the connecting claw 123 is arranged on one end of the through pipe 122 away from the discharging member 11 and extends towards the side away from the discharging member 11.

[0036] The design of the through pipe 122 increases the connection strength between the linkage 12 and the material carrying assembly 21 and improves the stability of their connection. The claws 121 are arranged on the outer wall surface of the through pipe 122, which can enhance the strength and rigidity of the linkage 12, enhance the mechanical strength and durability of the entire linkage 12, and avoid the possibility of breaking or damaging the linkage 12 when it cooperates with the discharging member 11. At the same time, arranging the claws 121 on the outer wall surface of the through pipe 122 also facilitates the assembly and positioning of the claws 121 and the discharging member 11, and enables the cooperation mode of the discharging member 11 and the linkage 12 to be observed more intuitively. The connecting claw 123 extending away from the discharging member 11 is arranged on the through pipe 122, which enhances the connection strength of the assembly of the linkage 12 and other components and increases the assembly mode of the linkage 12 and other components.

[0037] Preferably, the outer wall surface of the through pipe 122 is sleeved with a mounting disc 124, which is located at the end of the through pipe 122 away from the discharging member 11. Along the moving direction of the load carrying assembly 21, the extension axis of the clamping jaw 121 and the extension axis of the connecting jaw 123 are the same. Specifically, in the embodiment, the clamping jaw 121 and the connecting jaw 123 are both arranged on the mounting disc 124 and are located on two sides of the mounting disc 124, respectively. That is, the clamping jaw 121 is located on the side surface of the mounting disc 124 facing the discharging member 11, and the connecting jaw 123 is located on the side surface of the mounting disc 124 away from the discharging member 11. The clamping jaw 121 and the connecting jaw 123 are both located on the same extension axis. The purpose of such arrangement is that when the linkage member 12 is pushed by the discharging member 11 to rotate, the connecting jaw 123 can be connected with other components and push them to rotate synchronously, so as to keep the linkage member 12 and the components cooperating with it consistent during rotation.

[0038] As shown in Figure 4 The connecting jaw 123 includes a first connecting jaw 1231 and a second connecting jaw 1232. The first connecting jaw 1231 and the second connecting jaw 1232 are arranged in sequence and cross each other along the circumferential direction of the through pipe 122. Specifically, the first connecting jaw 1231 is provided with a guide protrusion 1231 at the end facing away from the discharging member 11. The guide protrusion 1231 protrudes in the radial direction perpendicular to the moving direction of the load carrying assembly 21, so as to form an “arrow structure”. The second connecting jaw 1232 is provided with a contraction structure 1232 at the end facing away from the discharging member 11. The outer edge of the second connecting jaw 1232 gradually contracts toward the side away from the discharging member 11 to form the contraction structure 1232.

[0039] In the embodiment, the connecting claws 123 are arranged in two different structures and cross each other, which increases the reliability of the connection between the connecting claws 123 and other components and improves the stability of the overall structure of the connecting claws 123. In addition, the first connecting claw 1231 123 is arranged in the above structure, and the design of the guide protrusion 12311 can prevent the linkage 12 from deviating during movement on other components, ensuring that the linkage 12 moves in the preset direction to maintain the stability of the movement trajectory of the material discharge assembly 100. At the same time, the guide protrusion 12311 can also increase the connection strength between the first connecting claw 1231 123 and other components, thereby improving the stability of the connection between them. In addition, the second connecting claw 1232 123 is arranged in the above structure, and the design of the contraction structure 12321 reduces the contact area between the second connecting claw 1232 123 and other components, thereby reducing the friction and wear between them, prolonging the service life of the linkage 12, and the contraction structure 12321 on the second connecting claw 1232 123 plays a guiding role in its movement on other components, so that the linkage 12 can move in the preset direction to maintain the stability of the movement trajectory of the material discharge assembly 100.

[0040] As shown in Figure 3 The outer wall surface of the discharge member 11 is provided with a clamping cover 111, which is located at one end of the discharge member 11 close to the linkage 12, and the end of the clamping cover 111 facing the linkage 12 is provided with an abutting groove 112 for abutting with the clamping claw 121. Therefore, the design of the clamping cover 111 and the abutting groove 112 ensures the precise positioning of the linkage 12 on the discharge member 11 and avoids the deviation of the linkage 12 relative to the discharge member 11, thereby improving the stability of the movement trajectory of the material discharge assembly 100. In addition, such design also increases the connection strength between the discharge member 11 and the linkage 12, thereby improving the structural stability when the two abut.

[0041] Further, the outer wall surface of the clamping cover 111 is provided with a plurality of protrusions 113, which are arranged in sequence and spaced apart along the circumferential direction of the clamping cover 111. The extension direction of the protrusions 113 is the same as the movement direction of the material carrying assembly 21, and the abutting groove 112 is formed between adjacent protrusions 113 and on the side surface facing the linkage 12.

[0042] By increasing the protrusions 113 on the outer wall surface of the clamping cover 111, the structural strength of the discharge member 11 itself is improved, and the positioning accuracy and reliability of the cooperation between the discharge member 11 and other components are also enhanced. Therefore, when assembling the material discharge assembly 100, the position of the discharge member 11 can be positioned by the protrusions 113 to realize subsequent installation, which simplifies the assembly process and improves the installation efficiency.

[0043] In addition, in the embodiment, the discharge member 11 and the linkage member 12 are both integrally formed structures, which can make them have higher strength and rigidity, so that the linkage member 12 can withstand greater thrust and torque from the discharge member 11, improving the durability of the linkage member 12. In addition, the integrally formed structure simplifies the installation process of the material discharge assembly 100 and makes the components of the material discharge assembly 100 more compact.

[0044] In other embodiments, only the clamping claw 121, the connecting claw 123 and the mounting disc 124 of the linkage member 12 can be integrally formed structures, which are integrally arranged on the outer wall surface of the through pipe 122 for easy replacement and removal. The specific structure of the linkage member 12 and the discharge member 11 can be set as needed.

Embodiment 2

[0046] As shown in Figures 5-6 Embodiment 2 discloses a cosmetic pen 200, which comprises a pen barrel assembly 22, a material carrying assembly 21 and the material discharge assembly 100 of Embodiment 1. The material carrying assembly 21 and the material discharge assembly 100 are arranged inside the pen barrel assembly 22, the material carrying assembly 21 is arranged at the outlet end of the pen barrel assembly 22, and the material discharge assembly 100 is arranged at one end of the material carrying assembly 21 away from the outlet end, for pushing the material carrying assembly 21 to move relative to the pen barrel assembly 22.

[0047] Therefore, in the embodiment, the cosmetic pen 200 adopts the material discharge assembly 100 of Embodiment 1, so that the material carrying assembly 21 can move along the discharge direction X of the discharge member 11 under the pushing action of the discharge member 11, i.e. the material carrying assembly 21 can extend relative to the pen barrel assembly 22, thereby accurately controlling the discharge of the material carrying assembly 21. At the same time, the user only needs to push the discharge member 11 with one hand to drive the material carrying assembly 21 to move, which simplifies the user's operation steps and improves the convenience of using the cosmetic pen 200.

[0048] The "discharge direction X" refers to the direction in which the material carrying assembly 21 moves and gradually extends relative to the pen barrel assembly 22, so that the user can use the material at the outlet end of the pen barrel assembly 22. The "material" refers to lipstick, eye shadow, lip gloss, lip balm, eyeliner balm body, sunscreen stick, body fragrance or deodorant stick, etc.

[0049] The driving principle of the extension or retraction of the material carrying assembly 21 relative to the pen barrel assembly 22 in the cosmetic pen 200 can be referred to other existing technologies, which will not be described here.
