Description
Technical Field
[0001] The present application relates to the field of cosmetics, and in particular to a retractable makeup pen. Background Art
[0002] A makeup pen is a beauty tool used for drawing lip contour lines, the entire eyelid, eyebrows, and their defects, etc. The makeup pen usually contains liquid, paste or cream cosmetics.
[0003] In the related art, the makeup pen sequentially includes a pen cap, a pen barrel and a tail cap. The pen cap is located at one end of the pen barrel, the tail cap is located at the other end of the pen barrel, the pen cap is sleeved on the pen barrel, the tail cap and the pen barrel rotate relative to each other. A gel is placed in the pen barrel, a nut is provided in the pen barrel, the nut is fixed relative to the pen barrel, a screw rod is provided on the tail cap, the screw rod is threadedly connected with the nut, and one end of the screw rod passing through the nut is connected with a piston. The piston slides in the pen barrel to push out the gel. During actual operation, the operator removes the pen cap and rotates the tail cap to drive the rotation of the screw rod. The screw rod cooperates with the nut to move the screw rod away from the tail cap, so as to push the piston, and the piston pushes out the gel in the pen barrel.
[0004] The following defects exist in the above-mentioned related art. When the tail cap rotates to drive the screw rod to rotate, due to the heaviness of the gel, there is a buffer time for discharging. When the gel is pushed by the piston, it is difficult to push out the gel in the early stage, which is likely to give the user an illusion. Therefore, the tail cap is rotated by a large angle to increase the moving distance of the piston. When the buffer time of the gel has passed, the gel is likely to overflow excessively, resulting in waste of the gel. Utility Model Content
[0005] In order to improve the problem of the large rotation angle of the tail cap, the present application provides a retractable makeup pen. [[ID=2 ]]
[0006] The retractable makeup pen provided by the present application adopts the following technical solutions:
[0007] A retractable makeup pen includes a pen barrel and a tail cap. The tail cap and the pen barrel rotate relative to each other. A pushing component for controlling the pushing out of the gel is provided in the tail cap. The pushing component includes a screw rod and a spring. A first ratchet is provided on the spring. A nut is provided in the pen barrel. A second ratchet cooperating with the first ratchet is provided on the nut. A buffer section is formed between two adjacent second ratchets.
[0008] By adopting the above technical solutions, when the gel needs to be used, the operator can rotate the tail cap and push out the gel through the pushing component. The rotation of the tail cap can drive the screw rod to rotate forward, and the material is pushed by the piston. When the first ratchet slides over the second ratchet, the first ratchet can slide in the buffer section between the two second ratchets, forming the effect of the screw rod retracting to avoid excessive overflow of the material.
[0009] Preferably, the number of the first ratchet teeth does not exceed that of the second ratchet teeth, and the number of the second ratchet teeth is a multiple of two.
[0010] By adopting the above technical solution, by setting different numbers of the first ratchet teeth and the second ratchet teeth, the maximum rotation angle of the tail cap is set to be applicable to different types of cosmetics.
[0011] Preferably, the pushing component further includes a piston. One end of the screw rod passes through the nut and is connected to the piston. The spring is sleeved on the screw rod, and the first ratchet tooth is fixedly connected to one end of the spring facing the nut.
[0012] By adopting the above technical solution, when an operator rotates the tail cap, the rotation of the tail cap can drive the rotation of the screw rod and the spring. The screw rod cooperates with the nut, and the screw rod can push the piston to move, and the piston can push out the gel; the rotation of the spring can drive the rotation of the first ratchet tooth, facilitating the first ratchet tooth to slide past the second ratchet tooth and enter the buffer section.
[0013] Preferably, a control rod is fixedly connected to the tail cap. The screw rod is hollow, and the control rod is inserted into the screw rod.
[0014] By adopting the above technical solution, the control rod can limit the movement of the screw rod, thereby limiting the movement of the piston, reducing the possibility of the screw rod deviating, and thus reducing the possibility of the piston deviating, facilitating the piston to push the gel to move.
[0015] Preferably, a first convex strip is fixedly connected to the control rod, and a first groove is formed in the inner wall of the screw rod. The first groove is for the first convex strip to be embedded.
[0016] By adopting the above technical solution, when the tail cap is installed, the tail cap is moved to drive the movement of the first convex strip, so that the first convex strip is embedded into the first groove. The first convex strip can limit the screw rod, facilitating the tail cap to drive the rotation of the screw rod.
[0017] Preferably, the tail cap and the pen barrel are detachably connected. One end of the tail cap extends into the pen barrel. An annular block is fixedly connected to the tail cap, and an annular groove is formed in the inner wall of the pen barrel. The annular groove is for the annular block to be embedded.
[0018] By adopting the above technical solution, when the tail cap needs to be installed, the tail cap is moved to drive the movement of the annular block, so that the annular block is embedded into the annular groove. The annular groove can limit the annular block, thereby limiting the tail cap to realize the installation of the tail cap. The annular groove also limits the rotation of the annular block to facilitate the tail cap to drive the movement of the screw rod.
[0019] Preferably, a second convex strip is fixedly connected to the inner wall of the tail cap, and a second groove is formed in the spring. The second groove is for the second convex strip to be embedded.
[0020] By adopting the above technical solution, when installing the spring and the end cap, move the spring so that the second rib can be embedded into the second groove. The second rib can limit the spring, enabling the spring and the end cap to be relatively positioned, facilitating the rotation of the end cap driving the spring.
[0021] Preferably, a first limiting block is fixedly connected to the nut, and a second limiting block is fixedly connected to the inner wall of the pen barrel. There are multiple second limiting blocks, and a limiting groove is formed between two adjacent second limiting blocks for the first limiting block to be embedded.
[0022] By adopting the above technical solution, when the first limiting block moves to the limiting groove, the limiting groove can limit the first limiting block, thereby limiting the nut, making the nut relatively fixed in the pen barrel, facilitating the movement of the screw rod driving the piston.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. Through the settings of the first ratchet tooth, the second ratchet tooth, and the buffer section, when gel needs to be used, the operator can rotate the end cap, and the gel can be pushed out through the pushing component. The rotation of the end cap can drive the screw rod to rotate forward, and the piston pushes the material. When the first ratchet tooth slides over the second ratchet tooth, the first ratchet tooth can slide within the buffer section between the two second ratchet teeth, forming the effect of the screw rod retracting, avoiding the excessive overflow of the material;
[0025] 2. Through the settings of the annular block and the annular groove, when the end cap needs to be installed, move the end cap to drive the movement of the annular block, so that the annular block is embedded into the annular groove. The annular groove can limit the annular block, thereby limiting the end cap, realizing the installation of the end cap. The annular groove also limits the rotation of the annular block, facilitating the movement of the end cap driving the screw rod. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0034] In order to make the invention objectives, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0035] The following will further describe the present application in detail with reference to the attached Figure 1-7 This application will be further described in detail below.
[0036] The embodiments of the present application disclose a retractable cosmetic pen. As Figure 1 and 2 shown, it includes a pen barrel 1 and a tail cap 2. The tail cap 2 and the pen barrel 1 are detachably connected. A pushing component 3 for controlling the ejection of the gel is provided in the tail cap 2, and one end of the tail cap 2 facing the pen barrel 1 extends into the pen barrel 1. An annular block 22 is fixedly connected to the end of the tail cap 2 extending into the pen barrel 1. An annular groove 11 is formed on the inner wall of the pen barrel 1 for the annular block 22 to be embedded. When the annular block 22 is embedded in the annular groove 11, the operator can rotate the tail cap 2, and the tail cap 2 can drive the annular block 22 to rotate within the annular groove 11.
[0037] As Figure 2As shown, a control rod 21 is fixedly connected inside the tail cover 2. The pushing component 3 includes a screw rod 31 which is hollow and sleeved on the control rod 21. A first rib 211 is fixedly connected to the control rod 21, and a first groove 311 is formed on the inner wall of the screw rod 31 for the first rib 211 to be embedded. During actual operation, the operator needs to sleeve the screw rod 31 on the control rod 21. At this time, the first rib 211 is embedded in the first groove 311 to realize the relative fixation of the screw rod 31 and the control rod 21, facilitating the rotation of the screw rod 31 driven by the tail cover 2.
[0038] As Figure 3 shown, a nut 4 is provided inside the pen holder 1. The screw rod 31 is threadedly connected to the nut 4. A first limiting block 43 is fixedly connected to the nut 4, and a second limiting block 12 is fixedly connected to the inner wall of the pen holder 1. There are multiple first limiting blocks 43 and second limiting blocks 12. A limiting groove 13 is formed between two adjacent second limiting blocks 12 for the first limiting block 43 to be embedded. A retaining edge 44 is fixedly connected to the nut 4. When the first limiting block 43 is embedded in the limiting groove 13, the retaining edge 44 abuts against the second limiting block 12. When installing the nut 4, move the nut 4 so that the nut 4 drives the first limiting block 43 to move into the limiting groove 13, and the retaining edge 44 abuts against the second limiting block 12. The limiting groove 13 can position the first limiting block 43 in the circumferential direction, and the second limiting block 12 can support the retaining edge 44, making the nut 4 relatively fixed inside the pen holder 1, thus realizing the installation of the nut 4. After the nut 4 is installed, the operator can rotate the tail cover 2, and the tail cover 2 can drive the screw rod 31 to rotate. Since the screw rod 31 is threadedly connected to the nut 4, rotating the tail cover 2 can control the rising or falling of the screw rod 31.
[0039] As Figure 1 and 4 shown, the pushing component 3 includes a piston 32 which is located on the side of the nut 4 away from the tail cover 2. One end of the screw rod 31 passing through the nut 4 is connected to the piston 32. A positioning groove 312 is formed at one end of the screw rod 31 passing through the nut 4, and a positioning block 321 is fixedly connected to the piston 32 for the positioning block 321 to be embedded in the positioning groove 312. When installing the screw rod 31 and the piston 32, rotate the screw rod 31 so that one end of the screw rod 31 passes through the nut 4, and move the piston 32 so that the piston 32 drives the positioning block 321 to move into the positioning groove 312. The positioning groove 312 can limit the positioning block 321, making the screw rod 31 and the piston 32 relatively positioned, facilitating the rising or falling of the screw rod 31 driving the piston 32, and realizing the piston 32 to push out the gel.
[0040] As Figure 1 and 5As shown, the pushing component 3 further includes a spring 33. The spring 33 is sleeved on the screw rod 31. A second rib 23 is fixedly connected to the inner wall of the end cap 2. A second groove 332 is formed on the spring 33 for the second rib 23 to be embedded. When installing the spring 33, move the spring 33 and sleeve it on the screw rod 31, and the second rib 23 is embedded in the second groove 332. The screw rod 31 and the second rib 23 can limit the spring 33, so that the rotation of the end cap 2 drives the rotation of the spring 33. A contact strip 24 is fixedly connected to the inner wall of the end cap 2. When the spring 33 is installed and the end cap 2 is installed on the pen barrel 1, the contact strip 24 abuts against the upper end of the spring 33, and the contact strip 24 applies pressure to the spring 33, so that the lower end of the spring 33 abuts against the nut 4.
[0041] As Figure 1 , 6 and as shown in 7, a first ratchet 331 is fixedly connected to one end of the spring 33 facing the nut 4, and a second ratchet 41 is fixedly connected to one end of the nut 4 facing the spring 33. The number of the first ratchets 331 does not exceed that of the second ratchets 41, and the number of the second ratchets 41 is a multiple of two. In the embodiment of the present application, two first ratchets 331 are provided and four second ratchets 41 are provided. A buffer section 42 is formed between two adjacent second ratchets 41. When the operator rotates the end cap 2, the end cap 2 drives the screw rod 31 to rotate, causing the screw rod 31 to move downward, and the screw rod 31 drives the piston 32 to move downward. The rotation of the end cap 2 also drives the rotation of the spring 33, and the spring 33 drives the first ratchet 331 to move. At this time, the gel can be pushed out; when the first ratchet 331 slides over the second ratchet 41, the first ratchet 331 slides into the buffer section 42. At this time, the first ratchet 331 can rotate left and right within the buffer section 42, so as to realize the rotation of the end cap 2 and the rise of the piston 32, control the amount of gel pushed out, reduce the situation of excessive gel overflow due to excessive rotation amplitude of the end cap 2, reduce the waste of gel, and facilitate the use of the operator.
[0042] The implementation principle of a retractable cosmetic pen in the embodiment of the present application is as follows:
[0043] The operator installs the screw rod 31 into the end cap 2, the spring 33 is sleeved on the screw rod 31, the nut 4 is threadedly connected to the screw rod 31, and the piston 32 is connected to one end of the screw rod 31. Then, the end cap 2 is moved so that the end cap 2 is installed on the pen barrel 1. At this time, the nut 4 is relatively fixed within the pen barrel 1. The operator can rotate the end cap 2, and the end cap 2 drives the screw rod 31 to rotate. The screw rod 31 drives the piston 32 to move downward to push out the gel. The rotation of the end cap 2 can drive the first ratchet 331 to rotate. When the first ratchet 331 slides past the second ratchet 41, the first ratchet 331 moves into the buffer section 42. At this time, the end cap 2 can be rotated back so that the end cap 2 drives the first ratchet 331 to move within the buffer section 42, thereby driving the piston 32 to rise and controlling the amount of gel pushed out, reducing the situation of excessive gel overflow due to too large a rotation amplitude of the end cap 2.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
