Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] In today's beauty market, where consumers increasingly value personalized and refined experiences, the ease of use and precision of lip balm, as a daily lip care and makeup product, have become key concerns for consumers. Traditional lip balm dispensing mechanisms often employ fixed strokes or single adjustment methods, failing to meet users' varying needs for lip balm dispensing in different scenarios, such as applying a light layer for daily care versus a thicker layer for repair. To address this issue, an adjustable lip balm dispensing mechanism has emerged. Through innovative mechanical structures and adjustment mechanisms, it achieves precise control over the amount of lip balm dispensed, providing users with a more user-friendly and efficient experience, and injecting new vitality into the design and manufacturing of beauty products.

[0026] The basic structure of this actuation mechanism consists of an outer shell, a lip balm carrier tube, an actuation component, and an adjustment component. The outer shell, serving as the external protection and gripping component, is typically made of a hard yet resilient plastic material. Its surface is treated with frosting or polishing processes to ensure a comfortable grip while providing good wear resistance and impact resistance, effectively protecting the internal structure. The lip balm carrier tube holds the lip balm; its smooth inner wall fits tightly to the balm, preventing it from shifting or spilling. The material must also possess good chemical stability to avoid reacting with the lip balm ingredients and affecting product quality.

[0027] The dispensing assembly is the core component for dispensing lip balm, mainly consisting of a push rod, a piston, and a transmission structure. The push rod is typically located at the rear of the outer casing for easy user operation; its material matches the casing and possesses a certain level of strength and wear resistance. The piston is installed inside the lip balm tube, in direct contact with the lip balm. It is usually made of highly elastic silicone or rubber, which not only tightly adheres to the tube wall to prevent backflow but also moves smoothly forward under the push rod's influence, dispensing the lip balm from the tube opening. The transmission structure is responsible for transmitting the linear motion of the push rod to the piston. Common transmission methods include threaded drives and gear drives. Threaded drives utilize mating threads on the push rod and piston; when the push rod is rotated, the advancing threads cause the piston to move axially along the lip balm tube. Gear drives use the meshing of gear sets to convert the rotational motion of the push rod into the linear motion of the piston. Both transmission methods achieve stable and reliable power transmission, ensuring the piston accurately dispenses the lip balm.

[0028] The adjustment component is key to the adjustable paste dispensing volume of this push mechanism. It mainly consists of an adjustment knob, a dial, and an adjustment screw. The adjustment knob is located on the side or rear of the casing for easy user operation; its surface usually has anti-slip textures or a raised design for easy rotation and adjustment. The dial is connected to the adjustment knob and has clear graduations and corresponding paste dispensing volume markings, allowing users to intuitively understand the currently adjusted paste dispensing volume setting. The adjustment screw is connected to the piston or transmission mechanism. When the adjustment knob is rotated, the adjustment screw rotates accordingly, changing its relative position to the piston or transmission mechanism, thus adjusting the piston's stroke range and adjusting the paste dispensing volume. For example, when the adjustment knob is rotated clockwise, the adjustment screw moves the piston backward, increasing the piston's stroke and increasing the amount of paste dispensed with each push of the push rod; conversely, rotating the adjustment knob counterclockwise decreases the piston stroke, reducing the paste dispensing volume.

[0029] In practical use, the adjustable lip balm dispenser demonstrates exceptional convenience and practicality. For daily lip care, users can adjust the dispenser to a smaller setting and gently push the lever to obtain the appropriate amount of lip balm, avoiding waste and ensuring even application for moisturizing. When lips are dry and require a thicker application for repair, or when using lip makeup as a base, the dispenser can be adjusted to a larger setting to obtain more balm at once for quick application. Furthermore, the dispenser can be adjusted to suit different textures and hardnesses of lip balms. For example, a smaller dispenser can be used with softer lip balms to prevent dripping, while a larger dispenser can be used with harder lip balms to ensure smooth application and even coverage.

[0030] Compared to traditional lip balm applicators, this adjustable dispensing mechanism offers significant advantages. Traditional mechanisms typically provide only a single dispensing amount, failing to meet diverse user needs and often resulting in wasted product or inconvenience. The adjustable dispensing mechanism, through its precise adjustment mechanism, allows users to flexibly control the amount of lip balm dispensed according to their needs and usage scenarios, greatly enhancing the user experience. Furthermore, this design helps improve the efficiency of lip balm use, reducing the need for repeated application due to improper dispensing, thus saving time and product usage.

[0031] Looking ahead, with the continuous development of materials science, precision manufacturing, and intelligent technologies, adjustable lip balm dispensing mechanisms are expected to see further innovation. The application of new lightweight, high-strength, and self-lubricating materials will reduce the weight and frictional resistance of the mechanism, improving the user experience and extending its lifespan. Advances in precision manufacturing processes, such as micro-injection molding and precision machining, will make the mechanism structure more compact and precise, reducing production costs. The introduction of intelligent technologies, such as integrating sensors and microcontrollers into the dispensing mechanism, will enable intelligent adjustment of the dispensing amount, automatically adjusting the amount based on environmental factors such as lip humidity and temperature, providing users with a more intelligent and personalized experience. Through continuous innovation and improvement, adjustable lip balm dispensing mechanisms will play a greater role in the beauty market, meeting the increasingly diverse needs of consumers and driving lip balm products towards higher quality and more user-friendly designs.

[0032] Please see Figure 1-3 As shown, this embodiment provides an adjustable lip balm pushing mechanism, including: a base 1 and a shell 2. The shell 2 is located on the upper side of the base 1. An inner shell 4 is provided on the upper side of the base 1. The inner shell 4 is snapped into the shell 2. A lifting component corresponding to the inner shell 4 is provided inside the base 1.

[0033] The lifting assembly includes a rotating component. The upper circumference of the rotating component is provided with a spiral groove 9 and a sliding plate 6. The inner wall of the sliding plate 6 is provided with a protrusion 13, which is located in the spiral groove 9. The base 1 is provided with an adjustment groove 17, and the sliding plate 6 is slidably engaged in the adjustment groove 17. The upper end of the rotating component is rotatably engaged in the adjustment groove 17, and the lower end of the rotating component extends to the outside of the base 1. Two guide rods 8 corresponding to the sliding plate 6 are installed between the upper and lower sides of the adjustment groove 17. The sliding plate 6 is located between the two guide rods 8. A support is provided on the upper side of the sliding plate 6. A square groove is provided on the upper side of the base 1. The square groove is connected to the inner cavity of the inner shell 4 and the adjustment groove 17. The rotating component and the support are both vertically inserted through the square groove. A lip balm body 12 is provided on the upper part of the support. The upper part of the support and the lip balm body 12 are both located in the inner shell 4. The lip balm body 12 is located between the upper side of the inner wall of the outer shell 2 and the support.

[0034] One application of this embodiment is as follows: In use, first pull the outer shell 2 upwards to separate it from the base 1, exposing the lip balm body 12 inside the inner shell 4. Then, rotate the rotating part at the bottom of the base 1. The rotation of the rotating part causes the spiral groove 9 on its surface to rotate synchronously. At this time, the protrusion 13 is guided by the inclined surface of the spiral groove 9, forcing the slide plate 6 to slide vertically upwards along the guide rods 8 on both sides. The upward sliding of the slide plate 6 pushes the support member upwards, thereby smoothly pushing the lip balm body 12 out of the inner cavity of the inner shell 4. Once the lip balm body 12 is exposed to a suitable length, stop rotating for use. After use, rotate the rotating part in the opposite direction. The spiral groove 9 guides the slide plate 6 downwards in the opposite direction, and the lip balm body 12 retracts into the inner shell 4 along with the support member. Finally, reattach the outer shell 2 to the base 1 to complete storage. It should be noted that all electrical devices involved in this application can be powered by a battery or an external power source.

[0035] The spiral groove 9 and the protrusion 13 work together to facilitate the rotation of the rotating component to drive the slide plate 6 to rise or fall, thereby controlling the extension and retraction of the lip balm body 12, improving the flexibility of adjusting the amount of lip balm dispensed, reducing the probability of spring fatigue and rebound failure, and thus reducing the possibility of the lip balm body 12 being exposed to the cavity of the inner shell 4 and being damaged or contaminated. The guide rod 8 and the slide plate 6 work together to reduce the probability of the slide plate 6 deviating or tilting when sliding, and improve the stability of the lip balm body 12 when rising or falling.

[0036] like Figure 2 As shown, the support member in this embodiment includes two support rods 10 mounted on the upper side of the slide plate 6. The support rods 10 pass through the square groove. The upper end face of the two support rods 10 is equipped with a lip balm base 11. The lip balm base 11 is slidably fitted inside the inner shell 4. The lip balm base 11 is located above the rotating member. The lip balm body 12 is disposed on the upper side of the lip balm base 11. The lip balm body 12 is located between the upper side of the inner wall of the outer shell 2 and the lip balm base 11. The lip balm body 12 is supported by the cooperation of the support rods 10 and the lip balm base 11.

[0037] like Figure 2 As shown, sliders are installed on both sides of the paste holder 11 in this embodiment, and grooves are provided on both sides of the inner wall of the inner shell 4. The sliders slide in the corresponding grooves. The stability of the paste holder 11 when sliding is improved by the cooperation of the sliders and the grooves.

[0038] like Figure 2 , 3As shown, the rotating component in this embodiment includes a rotating rod 5, which is rotatably fitted in an adjusting groove 17. The upper end of the rotating rod 5 is located in a square groove, and the rotating rod 5 is located between two support rods 10. A spiral groove 9 is provided on the periphery of the rotating rod 5, and a sliding plate 6 is slidably fitted on the periphery of the rotating rod 5. A grease seat 11 is located above the rotating rod 5, and a connecting seat is provided on the lower end face of the rotating rod 5. The connecting seat extends through to the outside of the base 1. By cooperating with the rotating rod 5 and the connecting seat, it is convenient for the user to directly rotate the connecting seat to drive the rotating rod 5 to rotate, thereby improving the convenience of operating the rotating component.

[0039] like Figure 3 As shown, the connecting seat in this embodiment includes a connecting block 3 installed on the lower end face of the rotating rod 5. The lower side of the base 1 is provided with a rotating groove corresponding to the connecting block 3. The rotating groove is connected to the adjusting groove 17. The connecting block 3 is rotatably fitted in the rotating groove. A knob 16 is installed on the lower end face of the connecting block 3. The knob 16 is located on the lower side of the base 1. Through the cooperation of the connecting block 3 and the knob 16, it is convenient for the user to rotate the knob 16 from the lower side of the base 1 to drive the rotating rod 5 to rotate.

[0040] like Figure 3 As shown, a bearing is installed on the circumference of the rotating groove in this embodiment. The bearing is installed on the circumference of the connecting block 3. The bearing reduces the friction between the connecting block 3 and the base 1 when the connecting block 3 rotates, thereby improving the smoothness of the operation of the knob 16.

[0041] like Figure 2 As shown, in this embodiment, guide blocks 7 are installed on both sides of the skateboard 6. The guide blocks 7 are slidably engaged with the corresponding guide rods 8. By cooperating with the guide blocks 7 and the guide rods 8, the probability of the skateboard 6 getting stuck due to uneven force when sliding is reduced, thereby improving the stability of the skateboard 6 when sliding.

[0042] like Figure 3 As shown, in this embodiment, the lower side of the outer shell 2 is equipped with four first magnetic strips 15, which are integrally formed. The upper side of the base 1 is equipped with second magnetic strips 14 corresponding to the first magnetic strips 15, which are integrally formed. The first magnetic strips 15 are located on top of the second magnetic strips 14. The first magnetic strips 15 and the second magnetic strips 14 cooperate to facilitate the quick adsorption connection between the outer shell 2 and the base 1.
