[0002] With the improvement of living standards, the beauty industry is booming, and nail art and makeup have become necessities for many women.

[0003] Most nail polish gels and nail polishes currently on the market are in glass containers, with the brush and bottle used separately. Glass is heavy and fragile, and the seal between the cap and the bottle is generally not tight, making it easy for spills to occur.

[0004] To address the aforementioned issues, existing technologies using plastic pen-shaped liquid cosmetic products, such as nail polish, lip oil, and concealer, are widely used by consumers. These liquid cosmetic pens have a gap near the tip, allowing the liquid to be squeezed out during use. However, during this process, air can enter the cavity containing the liquid. This air cannot escape, and with repeated pressing or squeezing, it accumulates, contaminating the liquid and causing evaporation, oxidation, and microbial contamination. This ultimately alters the texture, color, and odor, reduces efficacy, and may even produce substances harmful to the skin. Furthermore, the embedded snap-fit ​​connection between the pen body and tip in existing cosmetic pens makes leakage easy, especially in warmer environments. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] This embodiment discloses a vacuum pump type press-type makeup pen, referring to... Figures 1-2 The pen includes a pen body 1, a pen tip 2, and a pen cap 3. The pen body 1 has an inner liner 4. One end of the pen body 1 has a vacuum pump structure 5 connected to the inner liner 4. A first leak-proof component 6 is provided between the vacuum pump structure 5 and the inner liner 4. The pen tip 2 has a second leak-proof component 7 that works with the vacuum pump structure 5. The second leak-proof component 7 is connected to the vacuum pump structure 5 via a connector 8. The outer end of the pen body 1 has a button 9. The inner liner 4 has a squeeze sleeve 10 corresponding to the button 9. By providing the vacuum pump structure 5 in the pen body 1 and connecting it to the inner liner 4, when pressed, the air in the inner liner 4 is expelled through the vacuum pump structure 5, and the squeeze sleeve 10 moves to squeeze out the liquid, thereby effectively preventing the liquid from being contaminated and ensuring the preservation time and quality of the liquid. In addition, the first leak-proof component 6 between the vacuum pump structure 5 and the inner liner 4 and the second leak-proof component 7 in the pen tip 2 form a double-layer leak-proof structure, which can enhance the liquid leak-proof effect.

[0022] The vacuum pump structure 5 includes a pump head seat 51 connected to the inner liner 4. A pump body 52 is provided inside the pump head seat 51. A valve core assembly 53 is provided between the pump body 52 and the connector 8. A valve plate 54 is provided in the lower part of the pump body 52. ​​The liquid is inside the pump body 52. ​​The valve plate 54 is a backflow valve plate 54. When squeezing the liquid, pressing the button 9 drives the squeezing sleeve 10 to move towards the valve core assembly 53 inside the inner liner 4, so that the liquid continues to enter the second leak-proof assembly 7 after passing through the connector 8, and finally is squeezed out from the pen tip 2.

[0023] The valve core assembly 53 includes a spring seat 531 that extends into the pump body 52 at its lower part. The spring seat 531 is connected to the pump body 52 via a cap 532. A piston 533 is connected to the lower part of the spring seat 531. A plug 534 is axially inserted through the middle of the spring seat 531, connecting the piston 533, the cap 532, and the spring seat 531 to the pump body 52. ​​The upper and lower parts of the spring seat 531 are respectively provided with an upper mounting hole 5311 and a lower mounting hole 5312. An infusion hole 5313 is provided in the middle of the spring seat 531, communicating with the lower mounting hole 5312. A second inner annular groove 5314 is provided in the upper mounting hole 5311. The bottom end of the spring seat 531 is provided with a second outer protruding ring 5315 that engages with the bottom end face of the cap 532. The spring seat 531 has elastic support frames 5316 on both sides, and the lower end of the elastic support frame 5316 is located in the upper outer ring groove 523. Before the button 9 drives the squeezing sleeve 10, the piston 533 is not squeezed, and the block 534 is in a relaxed state, so the liquid can enter the spring seat 531. After the squeezing sleeve 10 moves and squeezes, the piston 533 and the block 534 are squeezed and move towards the spring seat 531. At the same time, the elastic support frame 5316 of the spring seat 531 is elastically compressed, so that the liquid enters the connector 8 from the infusion hole 5313, then continues to enter the second anti-leakage component 7, and finally is squeezed out from the pen tip 2.

[0024] The first leak-proof component 6 includes an external threaded collar 61 located at the lower part of the pump head seat 51 and an internal threaded hole 62 opened in the inner wall of the inner liner 4. A rubber sealing ring 63 is provided between the external threaded collar 61 and the internal threaded hole 62. The inner liner 4 is screwed to the pump head seat 51, and the rubber sealing ring 63 can effectively prevent liquid from leaking out from the gap between the inner liner 4 and the pump head seat 51.

[0025] The second leak-proof component 7 includes an installation cavity opened in the pen tip 2. The lower end of the installation cavity is provided with a push block 71 that cooperates with the connector 8. The upper end of the push block 71 is provided with a glass bead 72. A spring 73 is provided between the glass bead 72 and the outlet of the pen tip 2. A liquid outlet tube 74 is provided between the spring 73 and the installation cavity. When liquid enters the installation cavity, the connector 8 presses down the push block 71, causing the glass bead 72 to move down. Under the action of the spring 73, the liquid is forced into the liquid outlet tube 74 until the liquid outlet tube 74 delivers the liquid to the outlet of the pen tip 2 (on the brush).

[0026] The pump body 52 has a first inner ring groove 521 in its upper part. The end cap 532 has a first outer protruding ring 522 in its middle part that mates with the first inner ring groove 521. The upper and lower outer edges of the end cap 532 have an upper outer ring groove 523 and a lower outer ring groove 524, respectively. The pump body 52 has a device cavity in its lower part that facilitates the installation of the valve plate 54. Below the device cavity is an outer connecting cylinder 525 that mates with the extrusion sleeve 10. The extrusion sleeve 10 includes an inner concave ring 101 disposed on the inner wall of the inner liner 4. The inner concave ring 101 is provided with a stepped ring groove 102 that fits into the outer connecting cylinder 525. The first inner ring groove 521 and the first outer convex ring 522 are connected to each other, which facilitates the door cover to fix the spring 73 seat 531 to the pump body 52. ​​The outer connecting cylinder 525 can fit into the stepped ring groove 102 of the extrusion sleeve 10, which allows the extrusion sleeve 10 to squeeze out all the liquid in the inner liner 4 and at the same time expel the air in the inner liner 4, thereby effectively avoiding the liquid from being contaminated and ensuring the preservation time and quality of the liquid.

[0027] The lower part of the connector 8 is located in the upper mounting hole 5311. The lower part of the connector 8 is provided with a third outer protruding ring 81, which engages with the second inner ring groove 5314. The upper part of the connector 8 is located in the mounting cavity of the pen tip 2 and abuts against the push block 71. The connector 8 is provided with a liquid transition hole 82 that communicates with the infusion hole 5313 and the mounting cavity. The liquid transition hole 82 can send the liquid output from the infusion hole 5313 into the mounting cavity.

[0028] The piston 533 includes a sleeve 5331. The upper outer edge of the sleeve 5331 is provided with a fourth outer protruding ring 5332 that is connected to the inner wall of the lower mounting hole 5312. The lower outer edge of the sleeve 5331 is provided with a support ring 5333 that contacts the inner wall of the pump body 52. ​​The upper end of the support ring 5333 is abutted against the bottom end of the lower outer ring groove 524. When the fourth outer protruding ring 5332 is squeezed, it is squeezed into the lower mounting hole 5312 of the pump body 52, and the liquid is sent into the infusion hole 5313.

[0029] The working principle of this utility model is as follows: First, press button 9 to drive the extrusion sleeve 10 to move towards valve plate 54 inside the inner liner 4, causing the liquid piston 533 and block 534 to be squeezed towards spring seat 531, and causing the liquid to enter the liquid transition hole 82 of connector 8 from the infusion hole 5313. Then the liquid enters the mounting cavity. Connector 8 presses down push block 71, causing glass bead 72 to move down. Under the action of spring 73, the liquid is forced into outlet pipe 74 until outlet pipe 74 delivers the liquid to pen tip outlet, while expelling air from the inner liner 4. After releasing button 9, under the action of spring 73, glass bead 72 rebounds and push block 71 back up. Then push block 71 pushes connector 8 back, connector 8 pushes spring seat 531 back in the opposite direction, and piston 533 and block 534 rebound and relax. Under the action of valve plate 54, air can be prevented from entering the inner liner 4.

[0030] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
