Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging bottle cap technology, specifically a quantitative emulsion packaging bottle cap for cosmetics. Background Technology

[0002] An emulsion pump is typically installed at the opening of a container and is used by the user to manually press the pump to dispense a liquid, such as an emulsion, from the container for use. The emulsion pump dispenses a fixed amount of emulsion in a single complete press.

[0003] According to the cosmetic dispensing bottle cap disclosed in patent publication number CN 220115200 U, the device uses a rotating pump head to align a guide post with vertical slots of different depths. When the pump head is pressed, the amount of emulsion dispensed each time varies due to the different depths of the vertical slots, thus meeting the problem of different users having different emulsion needs. However, this device is not convenient for manual replacement of the pump head, which makes it inconvenient to manually change different sizes of dispensing nozzles, and therefore cannot be applied to different user groups, affecting the applicability of the device.

[0004] To address this issue, we propose a quantitative emulsion dispensing bottle cap for cosmetics. Utility Model Content

[0030] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-5As shown, this utility model provides a technical solution: a cosmetic quantitative emulsion dispensing bottle cap, including a cap body 1, a pump head 2 movably connected to the upper part of the cap body 1, a replacement head 4 disposed on the upper part of the pump head 2, an emulsion pump 5 installed inside the cap body 1, a liquid guide tube 6 connected to the upper part of the emulsion pump 5, and a connecting assembly 3 disposed inside the cap body 1. The connecting assembly 3 includes a disassembly and assembly mechanism 31 disposed inside the cap body 1. A sealing mechanism 32 is disposed inside the cap body 1. The disassembly and assembly mechanism 31 includes an installation groove 311 opened on the upper part of the pump head 2. A limiting groove 312 is opened on the inner wall of the installation groove 311, and a limiting groove 312 is fixedly connected to the inner wall of the limiting groove 312. Positioning post 313, a connecting block 314 is slidably connected to the outer wall of positioning post 313, an ejector ring 315 is slidably connected to the outer wall of positioning post 313, a first spring 316 is fixedly connected to the inner wall of positioning groove 312, an inner groove 317 is opened inside the pump head 2, a movable block 318 is slidably connected to the inner wall of inner groove 317, an inclined plate block 319 is fixedly connected to one side of movable block 318, a connecting rod 3110 is fixedly connected to the side of movable block 318 away from inclined plate block 319, a positioning block 3111 is fixedly connected to the outer end of connecting rod 3110, a second spring 3112 is fixedly connected to the inner wall of inner groove 317, and a snap-fit ​​groove 3113 is opened on the side wall of replacement head 4.

[0033] In this embodiment, the inclined plate block 319 is movably connected to the pump head 2 and the locking groove 3113. Through the cooperation of the mounting groove 311, the limiting groove 312, the limiting post 313, the connecting block 314, the ejection ring 315, the first spring 316, the inner groove 317, the movable block 318, the inclined plate block 319, the connecting rod 3110, the limiting block 3111, the second spring 3112, and the locking groove 3113, it is convenient for manual disassembly of the replacement head 4. This facilitates manual replacement of the replacement head 4 with different sized liquid outlet heads 326, making it suitable for different users and preventing the need for multiple presses by people with larger faces.

[0034] Furthermore, one end of the second spring 3112 is fixedly connected to the movable block 318, and the outer end of the connecting rod 3110 is movably connected to the pump head 2.

[0035] Furthermore, the connecting block 314 is fixedly connected to the replacement head 4.

[0036] Furthermore, the top of the first spring 316 is fixedly connected to the ejector ring 315.

[0037] Furthermore, there are three connecting blocks 314, which are equidistantly distributed on the outer wall of the replacement head 4.

[0038] When the replacement head 4 needs to be replaced, manually pulling the connecting rod 3110 outwards causes the movable block 318, which is fixedly connected to the inner end of the connecting rod 3110, to move the inclined locking block 319 outwards. This allows the inclined locking block 319 to separate from the locking groove 3113. Subsequently, under the elastic force of the first spring 316, the ejector ring 315 presses upwards against the connecting block 314. Since the connecting block 314 is fixedly connected to the replacement head 4, the inclined locking block 319 and the locking groove 3113 can quickly misalign, allowing the replacement head 4 to pop upwards. This makes it easier for manual removal of the replacement head 4. The replacement head 4 with different diameter dispensing heads 326 can then be replaced manually, making it suitable for different users and preventing the need for multiple presses by people with larger faces. This increases the device's versatility. Furthermore, when it is necessary to install the replacement head 4, the replacement head 4 is manually placed in the installation groove 311, and the connecting block 314 fixedly connected to the outer wall of the replacement head 4 cooperates with the limiting groove 312, so that the snap-fit ​​groove 3113 can achieve a vertical positioning effect, which makes it easier for the inclined snap-fit ​​block 319 to snap-fit ​​groove 3113. Then, the replacement head 4 is pressed down. Since the upper part of the inclined snap-fit ​​block 319 is inclined, when the replacement head 4 moves down, the inclined snap-fit ​​block 319 can be pressed into the inner groove 317. Then, when the replacement head 4 continues to move down, the second spring 3112 can cause the movable block 318 to drive the inclined snap-fit ​​block 319 to move outward under the action of elastic force, so that the inclined snap-fit ​​block 319 can snap-fit ​​groove 3113, thus completing the installation operation of the replacement head 4.

[0039] Example 2

[0040] Based on Example 1, a preferred embodiment of the cosmetic dispensing bottle cap provided by this utility model is as follows: Figures 1 to 5 As shown: The sealing mechanism 32 includes a first sealing ring 321 fixedly connected to the inner wall of the mounting groove 311, a groove 322 is provided at the bottom of the replacement head 4, a liquid outlet hole 325 is provided inside the replacement head 4, a sleeve 324 is fixedly connected to the inner wall of the groove 322, a second sealing ring 323 is fixedly connected to the inner wall of the groove 322, and a liquid outlet head 326 is provided at the outer end of the liquid outlet hole 325.

[0041] In this embodiment, the inner end of the liquid outlet 325 is connected to the groove 322, and the sleeve 324 is sleeved on the outside of the liquid guide tube 6. Through the cooperation of the first sealing ring 321, the groove 322, the sleeve 324, the liquid outlet 325, and the liquid outlet head 326, the replacement head 4 and the pump head 2 can have good sealing performance, thereby preventing the leakage of emulsion.

[0042] Furthermore, the second sealing ring 323 is disposed in the gap between the sleeve 324 and the groove 322.

[0043] When the replacement head 4 enters the installation groove 311, the sleeve 324 can be fitted over the outside of the liquid guide tube 6. After the replacement head 4 is installed, the first sealing ring 321 and the second sealing ring 323 can seal the emulsion, thereby preventing emulsion leakage. When a quantitative amount of emulsion needs to be dispensed, the replacement head 4 is manually pressed down to move the pump head 2 downward, thereby pressing the emulsion pump 5. Then, under the action of the emulsion pump 5, the emulsion can be conveyed upward into the liquid guide tube 6, and then sprayed out through the sleeve 324 and the liquid outlet 325 to the liquid outlet head 326.
