Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a raw material tube and a lipstick machine. Background Technology

[0002] With the continuous development of technology, intelligent and sophisticated equipment has been widely used in various industries, especially in the cosmetics industry. To meet consumers' demands for efficiency, convenience, and personalization, various intelligent devices have emerged. Lipstick, as an important part of the cosmetics market, is also seeing continuous innovation and progress in its production and usage.

[0003] In existing lipstick vending machine applications, although some highly automated equipment exists, such as for filling and packaging, most still rely on manual operation for ingredient mixing. This is not only inefficient but also makes it difficult to guarantee the accuracy and consistency of ingredient mixing. Especially in situations requiring frequent ingredient changes or mixing, such as lipstick customization shops and cosmetic production lines, manual ingredient mixing is simply insufficient to meet practical needs. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, this application provides a raw material tube and a lipstick machine to at least solve or alleviate the above-mentioned problems of the prior art. This technical solution can significantly improve safety and accuracy.

[0005] A raw material pipe includes an upper pipe body 1, an intermediate pipe body 2, and a lower pipe body 3. The upper pipe body 1 is connected to the intermediate pipe body 2, and the intermediate pipe body 2 is connected to the lower pipe body 3 to form a cavity for accommodating raw material 4. The outer wall of the upper pipe body 1 is connected to a driving device 6 via a transmission mechanism 5, and a lead screw 11 is provided in the upper pipe body 1. A pressure plate 12 is engaged on the lead screw 11. When the driving device 6 drives the upper pipe body 1 to rotate via the transmission mechanism 5, the upper pipe body 1 drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the pressure plate 12 to press down, thereby pushing the raw material 4 in the cavity toward the lower pipe body 3 until it forms raw material 4 that can flow out of the lower pipe body 3.

[0006] A raw material pipe includes: a pipe body, a lead screw 11, the pipe body having a cavity for accommodating raw material 4, the outer wall of the pipe body being connected to a driving device 6 via a transmission mechanism 5, and a pushing module being provided in the pipe body, so that when the driving device 6 drives the pipe body to rotate via the transmission mechanism 5, the pipe body drives the pushing module to move, so as to push the raw material 4 in the cavity toward the outside of the pipe body until the raw material 4 can flow out of the pipe body.

[0007] In this embodiment, the meshing design of the lead screw 11 and the pressure plate 12 allows the lead screw 11 to rotate and drive the pressure plate 12 to press down when the drive device 6 drives the upper tube 1 to rotate via the transmission mechanism 5. This mechanical structure ensures that the raw material 4 can be accurately and stably pushed into the lower tube 3, achieving precise distribution of the raw material. By controlling the rotation speed and direction of the drive device 6, the flow rate and direction of the raw material can be further controlled to meet different usage requirements. The upper tube 1 is connected to the drive device 6 via the transmission mechanism 5, allowing the entire raw material distribution process to be controlled by the drive device 6, greatly improving the convenience and efficiency of operation. The docking design between the upper tube 1, the middle tube 2, and the lower tube 3 ensures the structural stability and sealing of the raw material tube, avoiding problems such as raw material leakage or contamination. At the same time, the selection and configuration of the transmission mechanism 5 and the drive device 6 also consider the reliability and durability of the equipment, ensuring that the raw material tube can operate stably for a long time.

[0026] like Figures 1A-7 As shown, a raw material pipe includes: an upper pipe body 1, an intermediate pipe body 2, and a lower pipe body 3. The upper pipe body 1 is connected to the intermediate pipe body 2, and the intermediate pipe body 2 is connected to the lower pipe body 3 to form a cavity for accommodating raw material 4. The outer wall of the upper pipe body 1 is connected to a driving device 6 via a transmission mechanism 5. A lead screw 11 is provided in the upper pipe body 1, and a pressure plate 12 engages with the lead screw 11. When the driving device 6 drives the upper pipe body 1 to rotate via the transmission mechanism 5, the upper pipe body 1 drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the pressure plate 12 to press down, pushing the raw material 4 in the cavity toward the lower pipe body 3 until it forms raw material 4 that can flow out of the lower pipe body 3. The raw material includes at least one of a colorant and a base material.

[0027] In this embodiment, the meshing design of the lead screw 11 and the pressure plate 12 allows the lead screw 11 to rotate and drive the pressure plate 12 to press down when the drive device 6 drives the upper tube 1 to rotate via the transmission mechanism 5. This mechanical structure ensures that the raw material 4 can be accurately and stably pushed into the lower tube 3, achieving precise distribution of the raw material. By controlling the rotation speed and direction of the drive device 6, the flow rate and direction of the raw material can be further controlled to meet different usage requirements. The upper tube 1 is connected to the drive device 6 via the transmission mechanism 5, enabling the entire raw material distribution process to be automated by controlling the drive device 6, greatly improving the convenience and efficiency of operation. The docking design between the upper tube 1, the middle tube 2, and the lower tube 3 ensures the structural stability and sealing of the raw material tube, avoiding problems such as raw material leakage or contamination. At the same time, the selection and configuration of the transmission mechanism 5 and the drive device 6 also consider the reliability and durability of the equipment, ensuring that the raw material tube can operate stably for a long time.

[0028] Optionally, the upper end of the upper tube body 1 is provided with protruding teeth 13, and the transmission mechanism 5 includes a transmission sleeve 51. The transmission sleeve 51 rotates under the drive of the driving device 6. The rotation of the transmission sleeve 51 drives the upper tube body 1 to rotate, thereby driving the lead screw 11 to rotate.

[0029] Optionally, the transmission mechanism 5 further includes a helical gear 52, and a groove 511 is provided on the transmission sleeve 51. The transmission sleeve 51 engages the groove 511 with the tooth 13 on the upper tube body 1. The helical gear 52 meshes with the transmission sleeve 51. The driving device 6 is connected to the helical gear 52 so that the driving device 6 drives the helical gear 52 to rotate, and the rotation of the helical gear 52 drives the transmission sleeve 51 to rotate.

[0030] Therefore, the transmission mechanism 5, which incorporates the convex tooth 13, the transmission sleeve 51, and the helical gear 52 in the above-mentioned raw material pipe design, has the following technical advantages:

[0031] (1) The engagement design between the protruding tooth 13 and the groove 511 on the transmission sleeve 51 ensures the precise connection and transmission between the upper tube body 1 and the transmission sleeve 51. This design avoids slippage or error during the transmission process and ensures the precise distribution of raw material 4.

[0032] (2) The meshing design of the helical gear 52 and the transmission sleeve 51, as well as the connection between the helical gear 52 and the drive device 6, constitute a highly efficient power transmission system. This design enables the power of the drive device 6 to be transmitted quickly and accurately to the upper tube 1, thereby driving the lead screw 11 to rotate and realize the propulsion of the raw materials.

[0033] (3) The integrated design of the convex tooth 13, the transmission sleeve 51 and the helical gear 52 makes the entire transmission mechanism 5 compact and space-saving. This is very important for the overall design of the raw material pipe, as it helps to reduce the size and weight of the equipment and improve its portability and flexibility.

[0034] (4) The rotation of the helical gear 52 drives the transmission sleeve 51 to rotate, which in turn drives the upper tube body 1 to rotate. This transmission method has the characteristics of stability and reliability, and can ensure that the transmission mechanism 5 can still maintain stable performance during long-term and high-frequency use, without loosening or failure.

[0035] (5) Since the structure of the transmission mechanism 5 is relatively simple and the connection between each component is clear, the relevant components can be easily disassembled and replaced during equipment maintenance, which reduces maintenance costs and difficulty.

[0036] Optionally, the lead screw 11 is connected to a lead screw seat 111, the lead screw seat 111 is located in the inner cavity of the upper tube body 1, and the top of the lead screw seat 111 engages with the top of the upper tube body 1 to fix the lead screw seat 111 in the inner cavity of the upper tube body 1 so that the lead screw 11 can be driven to rotate synchronously when the upper tube body 1 rotates.

[0037] Therefore, in the design of the raw material pipe, the lead screw 11 is fixed in the inner cavity of the upper pipe body 1 by the lead screw seat 111, which has the following technical advantages:

[0038] (1) The lead screw seat 111 stably fixes the lead screw 11 in the inner cavity of the upper tube 1. When the upper tube 1 is driven to rotate, the lead screw 11 can rotate synchronously and stably. This design ensures that the raw material 4 can be pushed continuously and smoothly, avoiding the possible stagnation or unevenness of the raw material during the pushing process.

[0039] (2) The top of the lead screw seat 111 is engaged and fixed with the top of the upper tube body 1. This design makes the installation and disassembly of the lead screw seat 111 simple and convenient. When it is necessary to repair or replace the lead screw 11 or the lead screw seat 111, it can be easily removed, reducing maintenance costs and time.

[0040] (3) The fixing function of the lead screw seat 111 reduces the shaking and friction of the lead screw 11 during rotation, thereby reducing the wear and noise of the equipment. This is of great significance for improving the service life of the equipment and the comfort of the working environment.

[0041] (4) Through the fixing effect of the lead screw seat 111, the lead screw 11 can work more stably, reducing the failure and downtime caused by unstable rotation. This design improves the reliability and stability of the equipment and ensures the continuity and accuracy of the raw material distribution process.

[0042] Optionally, the drive device 6 includes a motor 61, a power output frame 62, and a power output shaft 63. The motor 61 is connected to the power output frame 62 to drive the power output frame 62 to rotate. The power output shaft 63 is connected to the power output frame 62 to drive the power output shaft 63 to rotate through the rotation of the power output frame 62. The helical gear 52 is sleeved on the power output shaft 63 to drive the helical gear 52 to rotate through the rotation of the power output shaft 63. The rotation of the helical gear 52 drives the transmission sleeve 51 to rotate.

[0043] Therefore, in the design of the raw material pipe, a drive device 6, including a motor 61, a power output frame 62, and a power output shaft 63, is introduced to drive the helical gear 52 and the transmission sleeve 51, thereby driving the upper pipe body 1 and the lead screw 11 to rotate. This has the following technical advantages:

[0044] (1) The motor 61 serves as a power source and can output power stably and efficiently. Through the transmission of the power output frame 62 and the power output shaft 63, the power can be transmitted to the helical gear 52 without loss, thereby ensuring the rapid and precise rotation of the transmission mechanism 5 and the upper tube 1.

[0045] (2) Motor 61 usually has a speed regulation function, which can precisely control the speed and direction of rotation. This allows the pushing speed of raw material 4 to be adjusted as needed, so as to achieve precise raw material distribution.

[0046] (3) Using motor 61 as a power source can automate the raw material distribution process. Users only need to set the corresponding parameters, and the equipment can automatically complete the pushing and distribution of raw materials, reducing the difficulty and labor intensity of manual operation.

[0047] (4) The combination of motor 61, power take-off frame 62, and power take-off shaft 63 has high operational stability and reliability. This design reduces downtime caused by mechanical failures and improves the overall performance and service life of the equipment.

[0048] (5) The relative independence of the motor 61 and the transmission mechanism 5 makes the maintenance and upkeep of the equipment simpler and more convenient. When a component fails, it can be replaced or repaired individually without disassembling the entire equipment.

[0049] Optionally, the lower tube 3 includes a nozzle 31 and a locking cap 32. The nozzle 31 is connected to the intermediate tube 2 so that the raw material 4 can be pushed outside the raw material tube. The locking cap 32 is used to lock the connection when the nozzle 31 is connected to the intermediate tube 2.

[0050] Therefore, the design of the lower pipe body 3, including the nozzle 31 and the locking cover 32, in the raw material pipe design has the following technical advantages:

[0051] (1) The nozzle 31 is directly connected to the intermediate tube 2, so that the raw material 4 can be smoothly pushed from the raw material tube to the outside. This design simplifies the raw material distribution process and improves the convenience of operation.

[0052] (2) The locking cap 32 provides a locking function when the nozzle 31 is connected to the intermediate tube 2, which effectively prevents waste or pollution caused by accidental leakage of raw materials during transportation or storage. This design increases the safety and reliability of the raw material tube.

[0053] (3) The locking cover 32 can not only prevent raw material leakage, but also protect the nozzle 31 from external environmental corrosion, such as dust and moisture, when the raw material is not in use, thereby extending the service life of the nozzle.

[0054] (4) The design of the locking cover 32 allows the nozzle 31 to be easily cleaned and maintained when needed. When the nozzle is clogged or needs cleaning, the user can easily access the nozzle by opening the locking cover to perform the necessary cleaning or maintenance work.

[0055] (5) The combined design of nozzle 31 and locking cover 32 makes the raw material tube more user-friendly and improves the user's operating experience and satisfaction. Users can easily control the distribution of raw materials according to their own needs without worrying about raw material leakage or nozzle damage.

[0056] Alternatively, for example, the nozzle 31 can be connected to the intermediate tube 2 via a collar 33.

[0057] Optionally, the lower tube body 3 further includes a locking spring 33, which is engaged on the outer wall of the locking cover 32 when the locking cover 32 locks the connection to perform a locking process on the locking cover 32.

[0058] Therefore, in the design of the raw material pipe, the introduction of a locking spring 33 into the lower pipe body 3 has the following technical advantages:

[0059] (1) When the locking cover 32 locks the connection between the nozzle 31 and the intermediate tube 2, the locking spring 33 can be stably locked on the outer wall of the locking cover 32, ensuring that the connection between the locking cover 32 and the raw material tube is tight and firm. This design effectively prevents the problem of raw material leakage caused by accidental loosening and improves the safety and reliability of the raw material tube.

[0060] (2) The use of locking spring 33 makes the locking operation of the locking cover 32 simpler and faster. The user only needs to align the locking cover 32 with the nozzle 31 and rotate it, and the locking spring 33 will automatically snap into the outer wall of the locking cover 32 to complete the locking process. This design reduces the user's operation steps and time, and improves the efficiency of use.

[0061] (3) The locking circlip 33 is usually made of elastic materials, such as stainless steel or spring steel, which have good wear resistance and corrosion resistance. This design enables the locking circlip 33 to maintain stable performance during long-term use, and it is not easy to be damaged or deformed, thereby extending the service life of the raw material tube.

[0062] (4) The design of the locking spring 33 enables the raw material tube to adapt to different working environments and conditions. Whether in high temperature, low temperature or humid environment, the locking spring 33 can maintain a stable locking effect, ensuring that the raw material tube can work normally in various environments.

[0063] (5) Because the locking spring 33 is simple in design and easy to replace, when the locking spring 33 is damaged or worn, the user can easily remove it and replace it with a new locking spring 33 without disassembling or repairing the entire raw material tube. This design reduces the maintenance cost and difficulty of the raw material tube.

[0064] Optionally, the lower tube 3 further includes an anti-backflow structure 7, which is disposed in the nozzle 31. When the raw material 4 is to be pushed outside the raw material tube, the anti-backflow structure is closed so that the raw material 4 can be pushed outside the raw material tube. When the pushing of the raw material 4 outside the raw material tube is to be stopped, the anti-backflow structure is opened so that the raw material 4 is blocked inside the raw material tube.

[0065] Therefore, the anti-backflow structure 7 included in the lower pipe body 3 plays a key role in the design of the raw material pipe and has the following technical advantages:

[0066] (1) The anti-backflow structure 7 in the nozzle 31 ensures that when the material 4 is stopped from being pushed to the outside of the material pipe, the material will not flow back into the pipe due to gravity or other reasons. This function is crucial in keeping the inside of the material pipe clean and preventing material contamination.

[0067] (2) When it is necessary to push raw material 4 to the outside of the raw material pipe, the anti-backflow structure closes, allowing the raw material to flow out smoothly. This design simplifies the operation process and improves work efficiency.

[0068] (3) By effectively preventing raw material backflow, the anti-backflow structure 7 reduces the waste of raw materials and avoids pipeline contamination and raw material cross-contamination that may be caused by backflow.

[0069] (4) The anti-backflow structure 7, as part of the raw material pipe design, increases the stability and reliability of the entire equipment. Its precise design and reliable performance ensure the stable operation of the raw material pipe under various working conditions.

[0070] (5) The design of the anti-backflow structure 7 enables it to adapt to different application scenarios, including those requiring precise control of raw material flow and prevention of backflow. This flexibility has led to the widespread use of the raw material pipe in multiple industries.

[0071] (6) The anti-backflow structure 7 is usually designed as a detachable or washable component, which makes it easy to maintain and clean when needed, extending the service life of the raw material pipe.

[0072] Optionally, the anti-backflow structure 7 includes a ball 71 and a spring 72 located in the nozzle 31. The spring 72 presses against the ball 71. When the raw material 4 is to be pushed out of the raw material tube, the spring 72 is squeezed, causing the ball 71 to open the nozzle 31 so that the raw material 4 can be pushed out of the raw material tube. When the pushing of the raw material 4 out of the raw material tube is to be stopped, the spring 72 returns to its original position, causing the ball 71 to block the nozzle 31 so that the raw material 4 is blocked inside the raw material tube.

[0073] Therefore, the anti-backflow structure 7, composed of ball 71 and spring 72, has the following technical advantages in the design of the raw material pipe:

[0074] (1) A simple and efficient anti-backflow mechanism is achieved by combining the ball 71 and the spring 72. When the raw material 4 is pushed, the ball 71 is pushed open to allow the raw material to pass through; when the pushing stops, the ball 71 is quickly reset under the action of the spring 72 to block the nozzle 31 and effectively prevent the raw material from flowing back.

[0075] (2) Because the anti-backflow structure 7 can quickly and accurately control the flow of raw materials, it helps to improve the accuracy of raw material distribution. This structure provides reliable performance in applications such as precision coating, dispensing, or other applications that require precise control of raw material quantity.

[0076] (3) By preventing raw material backflow, the accumulation and sedimentation of raw materials in the pipeline are reduced, thereby reducing the risk of pipeline blockage. This helps to keep the raw material pipeline unobstructed and extend the service life of the equipment.

[0077] (4) Effectively preventing raw material backflow means reducing the waste of raw materials caused by backflow. At the same time, it avoids pipeline contamination and cross-contamination of raw materials that may be caused by raw material backflow, and maintains the purity and consistency of raw materials.

[0078] (5) The anti-backflow structure consisting of ball 71 and spring 72 is relatively simple, easy to disassemble and clean. When replacement or cleaning is required, the user can easily complete these operations and keep the equipment in good condition.

[0079] (6) This anti-backflow structure is suitable for a variety of different types of raw materials and working environments. Whether it is a viscous liquid, a powdery substance or other types of materials, as long as the appropriate ball 71 and spring 72 are selected, an effective anti-backflow function can be achieved.

[0080] Based on the above embodiments, considering that the tube body can be an integral structure, a raw material tube is provided, which includes: a tube body, a lead screw 11, and a pressure plate 12. The tube body has a cavity for accommodating raw material 4. The outer wall of the tube body is connected to a driving device 6 through a transmission mechanism 5. The lead screw 11 is provided in the tube body, and the pressure plate 12 is engaged on the lead screw 11. When the driving device 6 drives the tube body to rotate through the transmission mechanism 5, the tube body drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the pressure plate 12 to press down, so as to push the raw material 4 in the cavity toward the outside of the tube body until the raw material 4 can flow out of the tube body.

[0081] In addition, this application embodiment also provides a raw material tube, which includes: a tube body, a lead screw 11, the tube body having a cavity for accommodating raw material 4, the outer wall of the tube body being connected to a driving device 6 via a transmission mechanism 5, and a pushing module being provided in the tube body, so that when the driving device 6 drives the tube body to rotate via the transmission mechanism 5, the tube body drives the pushing module to move, so as to push the raw material 4 in the cavity toward the outside of the tube body until raw material 4 that can flow out of the tube body is formed.

[0082] Optionally, the feeding module includes a lead screw 11 and a pressure plate 12. The lead screw 11 is disposed in the tube body, and the pressure plate 12 is engaged on the lead screw 11. When the driving device 6 drives the tube body to rotate through the transmission mechanism 5, the tube body drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the pressure plate 12 to press down, so as to push the raw material 4 in the cavity toward the outside of the tube body until the raw material 4 can flow out of the tube body.

[0083] Based on the above embodiments, a lipstick machine is provided, which includes the raw material tubes described in any embodiment of this application. The raw materials in each raw material tube are of different colors, and the raw materials in multiple raw material tubes can be mixed to obtain the desired lipstick color.

[0084] It should be noted that, in addition to its application in the field of lipstick vending machines, the aforementioned raw material tube of this application can also be applied to the following technical fields:
