Description

Technical Field

[0001] This utility model relates to the field of lip cosmetics technology, specifically to a cosmetic bottle, and more particularly to a lip essence cosmetic bottle. Background Technology

[0002] Lip serums are a type of lip cosmetic. They are designed to moisturize the lips and effectively prevent lip scarring. Currently, most lip serums on the market require opening the cap and applying the serum directly with a cotton swab. This introduces lip microorganisms into the container, and the opened container is also susceptible to dust and other impurities, potentially causing the serum to spoil.

[0003] Utility model patent CN220545953U discloses a lip serum, including a base, a tube, a tube cover, and a serum body. The base is rotatably mounted at the bottom of the tube, the tube cover is mounted on the outside of the tube, and the serum body is slidably mounted inside the tube. The outer surface of the tube cover is provided with a heat insulation layer, and the inside of the tube is provided with a cooling groove filled with coolant. A screw is fixedly mounted on the upper surface of the base, and an adjusting frame is threadedly connected to the circumference of the screw. A bracket is fixedly connected to the top of the adjusting frame, and the serum body is fixedly mounted on the bracket. In use, this prior art involves rotating the base to drive the screw to rotate, which in turn causes the adjusting frame to move on the screw. The movement of the adjusting frame on the screw causes the bracket to move, and the movement of the bracket causes the serum body to extend. Its structure is relatively complex and its operation is relatively cumbersome.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this utility model proposes a cosmetic bottle with a simple structure and convenient operation.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A cosmetic bottle includes a vacuum bottle with a piston inside and a bottom stopper fixed to the bottom of the vacuum bottle, the bottom stopper having an air hole; a vacuum pump core movably disposed inside the mouth of the vacuum bottle, the vacuum pump core being used to open or close the mouth of the vacuum bottle; a housing with an openable outer cover at a first end and a detachable connection between the second end of the housing and the vacuum bottle, a brush rod fixed inside the housing, the first end of the brush rod located inside the outer cover and the second end of the brush rod correspondingly connected to the vacuum pump core; a button on the housing, a transmission component between the button and the vacuum pump core, the button being pressed to drive the vacuum pump core to actuate, causing the vacuum pump core to draw cosmetic liquid from the vacuum bottle into the brush rod.

[0008] According to the above scheme, the transmission component includes a driving component on the button and a transmission component on the vacuum pump core. The driving component and the transmission component are connected accordingly, and a return spring is provided between the transmission component and the mouth of the vacuum bottle.

[0009] According to the above scheme, the driving component is formed with a limiting groove, and the transmission component slides within the limiting groove.

[0010] According to the above scheme, the button is movably mounted on the side wall of the housing, the driving component is inclinedly mounted on the button, the transmission component is inclinedly mounted on the vacuum pump core, and the vacuum pump core is vertically mounted inside the mouth of the vacuum bottle.

[0011] According to the above scheme, an installation opening is formed on the side wall of the housing, the button is movably disposed in the installation opening, and a limiting component is provided between the installation opening and the button.

[0012] According to the above scheme, the limiting component includes a first limiting part disposed on the mounting port and a second limiting part disposed on the button, with the first limiting part and the second limiting part correspondingly abutting each other.

[0013] According to the above scheme, the vacuum bottle has an inner cover threadedly connected to its mouth, and a limiting protrusion is provided on the outer wall of the transmission component. The two ends of the return spring abut against the limiting protrusion and the inner cover respectively.

[0025] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 4 As shown, the cosmetic bottle of this utility model includes a vacuum bottle 4, a piston 5 inside the vacuum bottle 4, a bottom plug 6 fixed to the bottom of the vacuum bottle 4, and an air hole 61 on the bottom plug 6; a vacuum pump core 9, which is movably disposed inside the bottle mouth of the vacuum bottle 4 and is used to open or close the bottle mouth of the vacuum bottle 4; a shell 2, the first end of the shell 2 is provided with an openable outer cover 1, the second end of the shell 2 is detachably connected to the vacuum bottle 4, a brush rod 7 is fixed inside the shell 2, the first end of the brush rod 7 is located inside the outer cover 1, and the second end of the brush rod 7 is correspondingly connected to the vacuum pump core 9; a button 8 is provided on the shell 2, and a transmission component is provided between the button 8 and the vacuum pump core 9. By pressing the button 8, the vacuum pump core 9 is driven to operate, so that the vacuum pump core 9 draws the cosmetic liquid in the vacuum bottle 4 into the brush rod 7. With this setup, when in use, opening the outer cover 1 and pressing the button 8 activates the vacuum pump core 9, opening the mouth of the vacuum bottle 4 and reducing the pressure inside the vacuum bottle 4. At this time, atmospheric pressure enters through the air hole 61, pushing the piston 5 upwards, thus maintaining the pressure inside the vacuum bottle 4 in balance with the atmospheric pressure. During this process, the cosmetic liquid inside the bottle is pushed out by the piston 5, passed through the vacuum pump core 9, and then drawn into the brush rod 7 for application. Its structure is simple, easy to operate, and can prevent external bacteria, microorganisms, dust, and other impurities from entering the vacuum bottle 4 and contaminating the cosmetic liquid, effectively extending the shelf life of the cosmetic liquid.

[0027] The cosmetic liquid is stored in a vacuum bottle 4, which provides better preservation. When not in use, the vacuum bottle 4 is in a vacuum state, preventing the cosmetic liquid from coming into contact with the outside air. When the cosmetic liquid in the vacuum bottle 4 is used up, it can be disassembled and replaced, effectively reducing the manufacturing cost of the shell 2, achieving plastic reduction, and being more environmentally friendly.

[0028] The flow rate of the cosmetic liquid can be adjusted by pressing button 8 to drive the movement of the vacuum pump core 9, achieving precise control.

[0029] Furthermore, the transmission assembly includes a drive component 81 mounted on the button 8 and a transmission component 91 mounted on the vacuum pump core 9. The drive component 81 and the transmission component 91 are connected accordingly, and a return spring 10 is provided between the transmission component 91 and the opening of the vacuum bottle 4. With this configuration, when the vacuum pump core 9 is not under force, it closes the opening of the vacuum bottle 4 under the action of the return spring 10. In use, pressing the button 8 drives the drive component 81 to drive the transmission component 91 to move the vacuum pump core 9, opening the opening of the vacuum bottle 4 and compressing the return spring 10. When the button 8 is released, the vacuum pump core 9 and the button 8 return to their original positions under the rebound force of the return spring 10.

[0030] Furthermore, the driving component 81 has a limiting groove 82 formed on it, and the transmission component 91 slides within the limiting groove 82. This arrangement ensures that the transmission component 91 and the driving component 81 are always connected, and when the button 8 is pressed to actuate the driving component 81, the transmission component 91 slides along the limiting groove 82, thereby actuating the vacuum pump core 9 and opening the mouth of the vacuum bottle 4.

[0031] Among them, the limiting groove 82 is a T-shaped groove.

[0032] Furthermore, the button 8 is movably mounted on the side wall of the housing 2, the driving component 81 is inclinedly mounted on the button 8, the transmission component 91 is inclinedly mounted on the vacuum pump core 9, and the vacuum pump core 9 is vertically mounted inside the mouth of the vacuum bottle 4.

[0033] The conventional liquid discharge method is vertical pressing and vertical discharge. This utility model changes the discharge method and makes more reasonable use of the installation space. Specifically, by pressing button 8 from the side of the housing 2, the vacuum pump core 9 is driven to discharge liquid vertically. Under the action of the transmission component, the horizontal movement is changed to vertical movement, which is convenient to operate and more in line with user habits. Moreover, pressing button 8 from the side of the housing 2 will not interfere with the brush rod 7, while vertical pressing is prone to interference with the brush rod 7.

[0034] Furthermore, a mounting opening 21 is formed on the side wall of the housing 2, and the button 8 is movably disposed within the mounting opening 21. A limiting component is provided between the mounting opening 21 and the button 8. The limiting component includes a first limiting part 22 disposed on the mounting opening 21 and a second limiting part 83 disposed on the button 8. The first limiting part 22 and the second limiting part 83 abut against each other. In this configuration, the first limiting part 22 and the second limiting part 83 limit the button 8, ensuring that the transmission component 91 and the driving component 81 remain connected and preventing the button 8 from disengaging.

[0035] Furthermore, the vacuum bottle 4 has an inner cap 3 threadedly connected to its opening, and a limiting protrusion 92 is provided on the outer wall of the transmission component 91. The two ends of the return spring 10 abut against the limiting protrusion 92 and the inner cap 3, respectively. The inner cap 3 has a through hole for the vacuum pump core 9 to pass through, and the vacuum pump core 9 is sealed with the through hole when no force is applied. This arrangement, through the limiting protrusion 92 and the inner cap 3, limits the movement of the return spring 10.

[0036] The second end of the shell 2 is fixedly connected to the inner cover 3, making it easy to assemble and disassemble the shell 2 and the vacuum bottle 4.

[0037] Furthermore, the vacuum pump core 9 is provided with a liquid suction end 94 and a liquid discharge end 95. The liquid suction end 94 is located inside the vacuum bottle 4, and the liquid discharge end 95 is located outside the vacuum bottle 4. The second end of the brush rod 7 is connected to the liquid discharge end 95. With this configuration, pressing the button 8 drives the vacuum pump core 9 to open the bottle mouth of the vacuum bottle 4, and the cosmetic liquid inside the bottle is introduced into the brush rod 7 after passing through the liquid suction end 94 and the liquid discharge end 95.

[0038] Furthermore, the brush handle 7 has a cotton head 71 at its first end, and a liquid guiding channel 73 inside the brush handle 7. The inlet end of the liquid guiding channel 73 is connected to the outlet end 95 of the vacuum pump core 9, and an outlet hole 72 is provided between the outlet end of the liquid guiding channel 73 and the cotton head 71. With this configuration, the cosmetic liquid introduced by the vacuum pump core 9 is used to wet the cotton head 71 on the brush handle 7 after passing through the liquid guiding channel 73 and the outlet hole 72. During use, the cosmetic liquid is applied through the cotton head 71.

[0039] Furthermore, the outer wall of the piston 5 is tightly fitted to the inner wall of the vacuum bottle 4. This design prevents the cosmetic liquid from leaking out while ensuring that the vacuum bottle 4 remains in a vacuum state.
