Description

Technical Field

[0001] This invention relates to the field of cream cosmetics, and more specifically to a cream cosmetic structure with electric multi-cream switching. Background Technology

[0002] With the continuous development of beauty and skincare products, various types of cream-based cosmetics are widely used in daily makeup and skincare. For example, cream-based beauty products such as lipsticks, lip balms, concealers, and contouring creams are typically housed in cylindrical containers. The cream protrudes from the top of the container via a rotating, lifting, or pushing mechanism for easy application. Due to their portability, ease of use, and wide applicability, these cream-based cosmetics have become an important part of daily beauty and skincare products.

[0003] Most existing cream-based cosmetic products employ a single-component structure, where only one cream component is housed within a container. A rotating base or central housing drives an internal spiral track or screw mechanism to raise or lower the cream axially, allowing it to extend or retract. While this type of structure is simple, has low manufacturing costs, and is widely used in the market, it still has certain limitations in practical application.

[0004] Firstly, as users' demands for diverse and personalized makeup effects continue to increase, single-component cream products often struggle to meet the needs of different scenarios. For example, during daily makeup application, touch-ups, or travel, users may need to use different colors or functions of cream cosmetics, such as lipstick, lip balm, or other functional cream products simultaneously. Traditional single-component cream designs require users to carry multiple cosmetics, which not only takes up space but also necessitates frequent product switching during actual use, making the process rather cumbersome.

[0005] Secondly, while some existing technologies employ multi-component combination structures, such as multi-cavity housing structures or replaceable core structures to integrate multiple cream products, most structures still rely on purely mechanical manual methods for cream switching and ejection. For example, cream selection is achieved by manually rotating the top cover or central structure to rotate the multi-cavity turntable, and then the cream is raised or lowered by rotating the bottom mechanism. These structures typically require multiple steps during use, resulting in a complex user experience. Furthermore, prolonged use can lead to problems such as inaccurate calibration, mechanical wear, or jamming.

[0006] Furthermore, in multi-component paste structures, due to the compact internal space and complex mechanical transmission path, relying solely on manual drive often results in insufficient torque or uneven force distribution. This is especially true when the paste viscosity is high or the ambient temperature is low, as the resistance to paste ejection increases significantly, thus affecting the user experience.

[0007] On the other hand, with the development trend of intelligent beauty products, more and more beauty devices are beginning to introduce electric drive structures and electronic control systems to improve the automation level and ease of use of the products. However, in the existing cream cosmetics field, there are still few products that combine multi-cream switching mechanisms with electric drive structures. Most products still remain at the level of traditional mechanical structures, lacking functions such as electric drive, precise indexing control, and intelligent operation. Summary of the Invention

[0008] To address the aforementioned issues, this invention provides an electrically operated multi-cream switching structure for cosmetic products. This structure enables stable circumferential switching of multiple creams within a limited shell space and achieves precise lifting control through an electric drive structure. It also integrates a battery, a circuit control system, and a charging interface, resulting in a compact and reliable overall structure that is easy to operate, provides accurate switching, and offers stable drive. This effectively overcomes the shortcomings of existing technologies.

[0016] in,

[0017] The circumferential drive mechanism drives the rotary switching component to rotate circumferentially through a gear transmission structure, so that different ointment components are aligned with the lifting drive component in the axial direction at a predetermined angle position.

[0018] The lifting drive mechanism adopts a screw drive structure, and the ointment assembly is driven to move axially up and down through the drive rod set on the screw drive mechanism;

[0019] The control component is electrically connected to the circumferential drive mechanism and the lifting drive mechanism respectively, and is used to control the switching, extension and retraction of the ointment.

[0020] As a preferred technical solution, the circumferential drive mechanism includes a first motor, a drive gear, and a driven gear connected to the rotation switching component;

[0021] The first motor output shaft is connected to the driving gear, the driving gear meshes with the driven gear, and the driven gear is coaxially and fixedly connected to the rotation switching component, thereby driving the rotation switching component to achieve circumferential rotation.

[0022] As a preferred technical solution, the first motor is fixedly mounted on the housing assembly by a motor bracket. The housing assembly includes a main housing, an inner housing, and a bottom cover. The inner housing is fixedly mounted on the bottom of the main housing, and the bottom cover is used to seal the bottom of the main housing. An extension bracket is provided on one side of the inner housing, and the motor bracket is fixedly mounted on one side of the extension bracket.

[0023] As a preferred technical solution, the rotary switching component includes a multi-cavity rotating component, which has multiple ointment receiving cavities inside. Each ointment component is respectively disposed in the ointment receiving cavity. The multi-cavity rotating component is indexed and rotated under the drive of the circumferential drive mechanism. The bottom of the multi-cavity rotating component is coaxially and fixedly connected to the bottom of the driven gear.

[0024] As a preferred technical solution, the lifting drive mechanism includes:

[0025] The system comprises a second motor, a lead screw, and a nut seat. The second motor is connected to the lead screw and drives it to rotate. The nut seat is located on one side of the drive rod and is threaded into the lead screw. The lead screw is mounted on a lead screw mounting bracket. A guide rod is provided on the lead screw mounting bracket. A guide groove is provided on one side of the nut seat, and the guide groove is guided and installed with the guide rod. The second motor is fixedly mounted on the bottom of the lead screw mounting bracket.

[0026] As a preferred technical solution, a fixed base is provided at the bottom of the multi-cavity rotating component, the drive shaft of the driven gear moves through the fixed base and is fixedly connected to the multi-cavity rotating component, and a first clearance hole is opened on the fixed base corresponding to the position of the drive rod, and the drive rod passes through the first clearance hole to lift the ointment assembly.

[0027] As a preferred technical solution, the ointment assembly includes an ointment movable plate and an ointment fixed plate. A tension spring is provided between the ointment movable plate and the ointment fixed plate. The upper and lower ends of the tension spring are fixedly connected to the ointment movable plate and the ointment fixed plate. The ointment is fixedly installed on the ointment movable plate. A second clearance hole is provided in the middle of the ointment fixed plate. The drive rod passes through the first clearance hole and the second clearance hole and contacts the bottom of the ointment movable plate. An ointment protective shell is installed on the outside of the ointment.

[0028] A magnetic rod is embedded in the paste, and the bottom of the paste is magnetically attracted to the metal paste movable plate, thereby completing the disassembly and replacement of the paste.

[0029] As a preferred technical solution, the top of the ointment assembly and the multi-cavity rotating component is provided with a top cover, the top cover is provided with an ointment outlet, and the top cover is provided with a screw cap to seal the ointment outlet.

The control buttons send control signals to the integrated circuit board, which then controls the forward and reverse rotation of the first motor and the second motor.

[0032] The beneficial effects of this invention are as follows: By setting up a gear-driven circumferential switching mechanism, this invention enables the multi-cavity rotating component to achieve stable, uniform, and controllable circumferential rotation under motor drive, thereby allowing different ointment components to be accurately aligned with the lifting drive mechanism at predetermined angular positions. Compared to traditional multi-ointment switching structures that rely on manual rotation, this invention uses a motor-driven combined with gear transmission method, which can effectively avoid positioning deviations caused by uneven rotational resistance, inaccurate indexing, or mechanical wear during manual operation, thus significantly improving the accuracy of ointment switching and structural reliability.

[0033] Meanwhile, this invention, by setting a lead screw drive structure as the lifting drive mechanism, enables the paste assembly to achieve stable, smooth, and controllable axial lifting motion under motor drive. Lead screw transmission features high positioning accuracy, good self-locking performance, and stable motion. Compared to traditional helical track structures or simple mechanical push rod structures, it can achieve more linear motion control under electric drive conditions, effectively avoiding problems such as paste breakage, uneven ejection, or structural jamming caused by uneven manual force application, thus improving the stability of the paste ejection process.

[0034] Furthermore, by arranging multiple cream components in a circumferential array within a multi-cavity rotating component, this invention enables the integration of different types or functions of cream cosmetics into the same device. This allows users to quickly switch between different creams without having to carry multiple products, saving space and significantly improving ease of use.

[0035] Furthermore, by setting up a magnetic paste installation structure, the present invention enables the paste components to be quickly disassembled and replaced. When the paste is used up or the user needs to change to a different type of paste, the original paste can be removed and replaced with a new paste component to complete the replacement, thereby making the product more flexible and convenient to use.

[0036] In addition, the present invention can also be equipped with an ultraviolet disinfection lamp at the top cover position. By controlling the ultraviolet disinfection function to be activated in the closed state, the top area of ​​the ointment is disinfected, thereby improving the hygiene and safety of the product during long-term use and further enhancing the user experience.

[0045] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0046] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0047] like Figures 1-5 As shown, the present invention discloses a multi-powder switching cream cosmetic structure with an overall columnar structure for easy hand-holding and carrying. Its exterior is composed of an outer shell assembly. The outer shell assembly includes a main shell 5, an inner shell 14, and a bottom cover 6. The inner shell 14 is fixedly installed inside the bottom of the main shell 5, providing support and limiting for the internal electric drive assembly and lifting drive assembly. The bottom cover 6 is installed at the bottom of the main shell 5, sealing the bottom of the main shell 5 and providing a sealed protection for the internal structure. One side of the inner shell 14 extends inward to form an extension bracket 105, which is used to fix and install the first motor 104 and its supporting structure in the circumferential drive mechanism 10, ensuring stable and reliable motor power output.

[0048] A rotary switching assembly is provided on the upper part of the main housing 5. The rotary switching assembly includes a multi-cavity rotating component 3. The multi-cavity rotating component 3 is uniformly provided with multiple paste receiving cavities along the circumferential direction for accommodating multiple paste components respectively.

[0049] The bottom of the multi-cavity rotating component 3 is fixedly mounted with a fixed base 11. The fixed base 11 is used to provide axial support and limit the multi-cavity rotating component 3. At the same time, a first clearance hole is opened at the position of the corresponding drive rod 16 so that the drive rod 16 can pass through during the lifting and lowering process.

[0050] The bottom of the multi-cavity rotating component 3 is coaxially and fixedly connected to the driven gear 101, which forms part of the circumferential drive mechanism 10. The circumferential drive mechanism 10 includes a first motor 104, a driving gear 102, and a driven gear 101.

[0051] The first motor 104 is fixedly mounted on one side of the extension bracket 105 via a motor bracket 103, which is used for positioning and shock absorption support of the first motor 104. The output shaft of the first motor 104 is fixedly connected to the drive gear 102, which meshes with the driven gear 101 for transmission. When the first motor 104 starts, the drive gear 102 drives the driven gear 101 to rotate, thereby driving the multi-cavity rotating component 3, which is coaxially fixed with it, to rotate in a circular direction, realizing the indexing rotational positioning of different ointment components at a predetermined angle position, so that the selected ointment component is aligned with the lifting drive mechanism 15 in the axial direction.

[0052] A lifting drive mechanism 15 is provided inside the main housing 5. The lifting drive mechanism 15 includes a second motor 152, a lead screw 153, a nut seat 161, a drive rod 16, and a lead screw mounting bracket 151. The lead screw mounting bracket 151 is fixedly installed inside the inner housing 14 to support the lead screw 153 and the second motor 152.

[0053] The second motor 152 is fixedly mounted at the bottom of the lead screw mounting bracket 151 and connected to the lead screw 153, used to drive the lead screw 153 to rotate around its own axis. The nut seat 161 is threadedly engaged with the lead screw 153. When the lead screw 153 rotates, the nut seat 161 moves along the axial direction of the lead screw. A drive rod 16 is fixedly connected to one side of the nut seat 161. A guide rod 21 is provided on the lead screw mounting bracket 151, and a guide groove is provided on one side of the nut seat 161. The guide groove and the guide rod 21 are guided and installed, thereby restricting the nut seat 161 to move only in a straight line along the axial direction during the movement without rotation, improving the stability and accuracy of the lifting movement.

[0054] Driven by the nut seat 161, the drive rod 16 moves up and down along the axial direction. When the selected ointment component is aligned with the drive rod 16, the drive rod 16 passes through the first clearance hole on the fixed base 11 and continues to pass through the second clearance hole in the middle of the ointment fixing plate 19, and contacts the bottom of the ointment movable plate 17, thereby lifting the ointment movable plate 17.

[0055] The ointment assembly includes an ointment 9, an ointment movable plate 17, an ointment fixed plate 19, and a tension spring 18. The ointment fixed plate 19 is fixedly disposed in the corresponding ointment receiving cavity of the multi-cavity rotating component 3. The ointment movable plate 17 is disposed above the ointment fixed plate 19. The tension spring 18 is disposed between the ointment movable plate 17 and the ointment fixed plate 19, and its upper and lower ends are respectively fixedly connected to the ointment movable plate 17 and the ointment fixed plate 19.

[0056] In this embodiment, a magnetic rod is embedded in the paste, and the bottom of the paste is magnetically attracted to the metal paste movable plate, thereby completing the disassembly and replacement of the paste.

[0057] When the drive rod 16 presses against the movable plate 17, the movable plate 17 moves upward against the elastic force of the tension spring 18, thereby causing the paste 9, which is fixedly installed on the movable plate 17, to extend axially. When the second motor 152 drives the lead screw 153 to rotate in the opposite direction, the drive rod 16 moves downward, the tension spring 18 releases its elastic potential energy, and the movable plate 17 and the paste 9 return to their original positions, realizing the automatic recycling of the paste. The paste 9 is externally fitted with a protective shell 4 to provide lateral protection for the paste 9 and prevent it from being contaminated or damaged when not in use.

[0058] A top cover 1 is provided on the top of the multi-cavity rotating component 3, and an outlet is provided on the top cover 1, which corresponds to the protruding position of each paste 9. A screw cap 2 is provided on the top cover 1 to seal the outlet and prevent the paste 9 from being exposed to air and causing it to dry and crack or become contaminated. The top cover 1 and the multi-cavity rotating component 3 are rotatably connected by a rotating shaft, so that the top cover 1 can switch between open and closed states.

[0059] An ultraviolet disinfection lamp is installed at the bottom of the top cover 1 on the side of the ointment outlet. The ultraviolet disinfection lamp is arranged corresponding to the top area of ​​the ointment 9. When the screw cap 2 is closed, the ultraviolet disinfection lamp can be activated by the control system to disinfect the top of the ointment, thereby improving the hygiene of use.

[0060] A control component is also provided inside the main housing 5. The control component includes control buttons 7, a battery 12, an integrated circuit board 13, and a charging interface 8. The control buttons 7 are located on the outside of the main housing 5. The control buttons 7 include a cream switching control button, a cream extension control button, and a cream retraction control button.

[0061] Control buttons 7 send control signals to integrated circuit board 13, which controls the forward and reverse rotation of the first motor 104 and the second motor 152 according to preset control logic, thereby realizing the circumferential switching of the multi-cavity rotating part 3 and the extension or retraction of the paste 9. The battery 12 is disposed inside the main housing 5 and is electrically connected to integrated circuit board 13, providing power to the first motor 104, the second motor 152 and the ultraviolet disinfection lamp.

[0062] The charging port 8 is located at the bottom of the bottom cover 6 or the bottom of the main housing 5 and is electrically connected to the integrated circuit board 13 and the battery 12 for charging the battery 12.

[0063] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
