The press-and-rotate liquid supply device includes a rotating sleeve with one end inside the pen body. A button is fitted onto the outer end of the rotating sleeve. Inside the rotating sleeve is a rotating wheel whose bottom end abuts against the top end of the button. A rotating gear is fitted onto the upper part of the rotating wheel. A screw passes through the middle of the rotating wheel. The bottom end of the screw abuts against the inner end of the button. The rotating gear is fitted onto the outside of the screw. A nut is screwed onto the screw. A piston is fitted onto the top end of the screw. The upper part of the pen body is detachably connected to... It has a pen tip. By pressing the button along the rotating sleeve, the screw is pushed upward, causing the screw to push the piston, which squeezes the liquid in the pen body out through the pen tip. This allows the pen tip to dispense a large amount of liquid. When the button is not pressed or after dispensing liquid, the rotating sleeve is driven to rotate, causing the rotating wheel and rotating gear to rotate, and the nut on the screw to rotate. This gradually moves the screw and piston upward, squeezing the liquid in the pen body out through the pen tip. This allows the pen tip to dispense a small amount of liquid. By using the press and rotate method to dispense liquid, the amount of liquid dispensed can be reasonably controlled, making it convenient to operate and more functional. Attached Figure Description

[0014] Figure 2 This is a schematic diagram of the structure of the press-and-rotate liquid supply device of this utility model. Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 , 2 As shown, a press-and-rotate liquid-dispensing makeup pen includes a pen body 1 and a pen cap 2. One end of the pen body 1 is equipped with a press-and-rotate liquid-dispensing device, which includes a rotating sleeve 4 with one end inside the pen body 1. A button 3 is fitted to the outer end of the rotating sleeve 4. A rotating wheel 5, the bottom end of which abuts against the top end of the button 3, is located inside the rotating sleeve 4. A rotating gear 6 is fitted onto the upper part of the rotating wheel 5. A screw 7 passes through the middle of the rotating wheel 5. The bottom end of the screw 7 abuts against the inner end of the button 3. The rotating gear 6 is fitted onto the outside of the screw 7. A nut 8 is screwed onto the screw 7. A piston 9 is fitted to the top end of the screw 7. A detachable connector is located at the upper end of the pen body 1. The pen tip 10, when pressed along the rotating sleeve 4 by button 3, pushes the screw 7 upward, causing the screw 7 to push the piston 9, which squeezes the liquid in the pen body 1 out through the pen tip 10. In this way, the pen tip 10 can dispense a large amount of liquid. In the original state without pressing button 3 or after pressing button 3 to dispense liquid, the rotating sleeve 4 is driven to rotate, which at the same time causes the rotating wheel 5 and rotating gear 6 to rotate, and the nut 8 on the screw 7 to rotate, gradually moving the screw 7 and piston 9 upward, slowly squeezing the liquid in the pen body 1 out through the pen tip 10. In this way, the pen tip 10 can dispense a small amount of liquid. By pressing and rotating to dispense liquid, the amount of liquid dispensed can be reasonably controlled, making it convenient to operate and more functional.

[0017] In this embodiment, the rotating sleeve 4 has several large toothed grooves 41 evenly distributed in the middle, and the upper outer wall of the button 3 has several large external teeth 31 that mate with the large toothed grooves 41. The upper part of the rotating sleeve 4 has several small toothed grooves 42. The screw 7 includes an oblong threaded rod body 71. The upper end of the threaded rod body 71 has a connector 72 with a stepped cross-section. The piston 9 has a stepped hole 91 in the middle that mates with the connector 72. When pressing to dispense liquid, the button 3 is pressed, and the large external teeth 31 move in conjunction with the large toothed grooves 41, pushing the screw 7 and nut 8 upward. This causes the screw 7 to push the piston 9, squeezing the liquid in the pen body 1 out through the pen tip 10, so that the pen tip 10 can dispense a large amount of liquid.

[0018] In this embodiment, the outer wall of the rotating gear 6 is uniformly provided with a plurality of small external teeth 61 that mate with the small tooth grooves 42; the upper end of the rotating gear 6 is provided with a plurality of upper push teeth 62; the upper end of the button 3 is uniformly provided with a plurality of upper push teeth 32; the lower end of the rotating wheel 5 is uniformly provided with a plurality of lower rotating teeth 83; the middle part of the rotating wheel 5 is provided with a through hole 52 for connecting with the screw 7; the middle part of the pen body 1 is uniformly provided with a plurality of middle tooth grooves 11; the outer wall of the nut 8 is uniformly provided with a plurality of middle external teeth 81 that mate with the middle tooth grooves 11; the middle part of the nut 8 is provided with a threaded hole 82 for threading with the screw 7; the upper end of the nut 8 is formed with a connecting groove; and the lower end of the nut 8 is provided with a tooth that mates with the upper push teeth 62. The screw 7 includes an elongated threaded rod 71 with a stepped-shaped connector 72 at its upper end. In the original state without pressing the button 3 or after pressing the button 3 to dispense liquid, the rotating sleeve 4 is driven to rotate. The upper push tooth 32 engages with the lower push tooth 83 to push the rotating wheel 5 to rotate upward. When the rotating wheel 5 rotates upward, it pushes the rotating gear 6 to rotate upward through the engagement of the small external tooth 61 and the small tooth groove 42. When the rotating gear 6 rotates upward, the upper top tooth 62 engages with the lower push tooth 83 to move the nut 8 upward, and at the same time, the screw 7 moves upward. Gradually, the screw 7 and the piston 9 move upward, and the liquid in the pen body 1 is slowly squeezed out through the pen tip 10, so that the pen tip 10 can dispense a small amount of liquid.

[0019] In this embodiment, the piston 9 has a stepped hole 91 in the middle that is connected to the connector 72. The piston 9 has a connector 92 and an elastic sealing ring 93 on the outer wall of the connector 92. The upper and lower ends of the elastic sealing ring 93 and the connector 92 are provided with telescopic sealing grooves. The stepped hole 91 is located at the lower end of the connector 92. By providing telescopic sealing grooves at both lower ends of the connector 92, the sealing effect between the elastic sealing ring 93 and the inner wall of the pen body 1 is improved.

[0020] In this embodiment, the upper end of the pen body 1 is provided with a screw connector 12, and the pen tip 10 is provided with a screw hole for screwing into the screw connector 12. By screwing the screw connector 12 into the screw hole, the pen tip 10 and the pen body 1 can be detached and connected, which is convenient for replacing different types of pen tips 10 (eyeliner, eyebrow pencil, concealer, lip gloss, etc.).

[0021] Based on the concept of this utility model, there may be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model.
