Abstract

The application provides a colorant conveying system and a lipstick machine. The colorant conveying system comprises a colorant pushing structure (2) and a colorant drop cutting structure (3). The colorant pushing structure (2) is connected with a colorant pipe (1) to push the colorant contained in the colorant pipe (1) to the colorant outlet of the colorant pipe (1) to form a colorant drop through the action of the colorant pushing structure (2). The colorant drop cutting structure (3) is communicated with the colorant pipe (1) to generate an air flow towards the colorant drop and cut the colorant drop through the air flow, so that the colorant drop is separated from the colorant outlet and enters a raw material mixing cavity. The cooperation of the colorant pushing structure (2) and the colorant drop cutting structure (3) is realized, and the colorant can be uniformly and stably pushed to the colorant outlet to form a colorant drop. The colorant drop cutting structure (3) uses the air flow to cut the colorant drop, so that the colorant drop can smoothly separate from the colorant outlet and enter the raw material mixing cavity for mixing.

Description

Technical Field

[0001] This application relates to the field of mechanical technology, and more specifically, to a pigment conveying system and a lipstick machine. Background Technology

[0002] In the cosmetics manufacturing industry, particularly in lipstick machines, the delivery and drop control of pigments are crucial steps in the manufacturing process. However, in practical applications, especially for pigment delivery in cosmetics such as lipsticks, the high viscosity and adhesion of pigments often make it difficult for pigment droplets to detach smoothly from the pigment outlet. This adhesion may stem from the physical properties of the pigment itself, such as viscosity and surface tension, or it may be related to the material and surface treatment of the pigment tube's inner wall.

[0003] When pigment droplets cannot detach smoothly due to viscosity and adhesion, they will accumulate at the pigment outlet and even block the pigment tube. In addition, the pigment droplets cannot detach in time to enter the mixing state, making subsequent mixing impossible. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a colorant conveying system and a lipstick machine, which at least solves or alleviates the problems of the prior art. This technical solution can significantly improve safety and accuracy.

[0005] A colorant delivery system, comprising: at least one colorant tube 1, a colorant pushing structure 2, and a colorant droplet cutting structure 3, wherein the colorant tube 1 contains colorant, and the colorant pushing structure 2 is connected to the colorant tube 1 so that, through the action of the colorant pushing structure 2, the colorant contained in the colorant tube 1 is pushed to the colorant outlet of the colorant tube 1 to form a colorant droplet; the colorant droplet cutting structure 3 is assembled at a position aligned with the colorant droplet to cut the colorant droplet, causing the colorant droplet to detach from the colorant outlet and enter a raw material mixing chamber pre-loaded with base material.

[0006] A lipstick machine includes the colorant delivery system described in any embodiment of this application.

[0007] In this embodiment, through the pigment pushing structure 2 and the pigment drop cutting structure 3, the pigment tube 1 contains pigment, and the pigment pushing structure 2 is connected to the pigment tube 1 so that the pigment contained in the pigment tube 1 is pushed to the pigment outlet of the pigment tube 1 to form a pigment drop by the action of the pigment pushing structure 2; the pigment drop cutting structure 3 is assembled at a position aligned with the pigment drop to cut the pigment drop, so that the pigment drop leaves the pigment outlet and enters the raw material mixing chamber pre-loaded with base material, thereby realizing the cooperation of the pigment pushing structure 2 and the pigment drop cutting structure 3. On the one hand, it ensures that the pigment can be pushed to the pigment outlet evenly and stably to form a pigment drop. Then, the pigment drop is cut by the pigment drop cutting structure 3 so that the pigment drop can smoothly leave the pigment outlet and enter the raw material mixing chamber pre-loaded with base material for mixing.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] See Figures 1A-4B As shown, a colorant conveying system includes: at least one colorant tube 1, a colorant pushing structure 2, and a colorant droplet cutting structure 3. The colorant tube 1 contains colorant, and the colorant pushing structure 2 is connected to the colorant tube 1 so that the colorant contained in the colorant tube 1 is pushed to the colorant outlet of the colorant tube 1 to form a colorant droplet by the action of the colorant pushing structure 2. The colorant droplet cutting structure 3 is assembled at a position aligned with the colorant droplet to cut the colorant droplet so that the colorant droplet leaves the colorant outlet and enters a raw material mixing chamber pre-loaded with base material.

[0034] In this embodiment, through the pigment pushing structure 2 and the pigment droplet cutting structure 3, the pigment tube 1 contains pigment, and the pigment pushing structure 2 is connected to the pigment tube 1 so that the pigment contained in the pigment tube 1 is pushed to the pigment outlet of the pigment tube 1 to form a pigment droplet through the action of the pigment pushing structure 2; the pigment droplet cutting structure 3 is assembled at a position aligned with the pigment droplet to cut the pigment droplet, so that the pigment droplet leaves the pigment outlet and enters the raw material mixing chamber pre-loaded with base material. This achieves the cooperation of the pigment pushing structure 2 and the pigment droplet cutting structure 3, ensuring that the pigment can be pushed evenly and stably to the pigment outlet to form a pigment droplet, and then, the pigment droplet cutting structure 3 uses airflow to cut the pigment droplet, allowing the pigment droplet to smoothly leave the pigment outlet and enter the raw material mixing chamber pre-loaded with base material for mixing.

[0035] Because the base material is pre-loaded into the raw material mixing chamber, while the colorant is added later, the entry points of the base material and colorant into the mixing chamber are separated. This allows for flexible selection of the base material and flexible configuration of the colorant according to the needs of the scenario, thereby improving the color gamut and enriching the texture of the mixed pigment. Furthermore, since the colorant is loaded into the mixing chamber independently of the base material, the colorant tube contains only the colorant, and its concentration can be independently adjusted. Similarly, the raw material mixing chamber pre-loads only the base material, and its concentration can also be independently adjusted. This increases the difficulty of selecting and adjusting both the base material and the colorant. During mixing, because the base material is pre-loaded into the raw material mixing chamber, only the colorant in the colorant tube needs to be loaded, thus reducing the difficulty of mixing.

[0036] Optionally, the pigment droplet cutting structure 3 includes: an airflow channel and an airflow control switch 32. The airflow channel is connected to the bottom of the pigment tube. The airflow channel is used to receive airflow input from an external airflow source. The airflow control switch 32 "opens" or "closes" the airflow channel 31 to control the airflow input from the external airflow source to enter the pigment tube through the airflow channel 31 and form an airflow towards the pigment droplet.

[0037] Optionally, the airflow channel includes an airflow input channel 31 and an airflow output channel 33. The airflow input channel 31 is used to receive airflow input from an external airflow source. The airflow control switch 32 "opens" or "closes" the connection between the airflow input channel 31 and the airflow output channel 33 to control the airflow input from the external airflow source to be input from the airflow input channel 31 to the airflow output channel 33 to form an airflow towards the pigment droplets.

[0038] Therefore, introducing a pigment droplet cutting structure 3 with an airflow input channel 31, an airflow control switch 32, and an airflow output channel 33 into the pigment delivery system has the following technical advantages:

[0039] (1) By using the airflow control switch 32, it is possible to precisely control whether the airflow input from the external airflow source flows into the airflow output channel 33, thereby achieving precise control over the cutting of pigment droplets. This precise control is crucial for ensuring the smooth detachment of pigment droplets and maintaining the stability of the manufacturing process.

[0040] (2) The airflow control switch 32 allows users to adjust the intensity and duration of the airflow according to actual needs. For pigments with different viscosities and adhesion, the optimal cutting effect can be found by adjusting the airflow parameters, thereby improving production efficiency and product quality. This can be done manually or electrically.

[0041] Optionally, the airflow control switch 32 is disposed between the airflow input channel 31 and the airflow output channel 33 to "open" or "close" the connection between the airflow input channel 31 and the airflow output channel 33.

[0042] Optionally, the airflow control switch 32 includes a valve core and a magnet. When the electromagnet is energized, it generates an electromagnetic force, which attracts the valve core to keep the connection between the airflow input channel 31 and the airflow output channel 33 in an "open" state. When the electromagnet is stopped, the electromagnetic force disappears, causing the valve core to reset. The reset of the valve core keeps the connection between the airflow input channel 31 and the airflow output channel 33 in a "closed" state.

[0043] Optionally, the airflow control switch 32 further includes a sealed cavity in which the valve core is disposed, and electromagnets are disposed on both sides of the cavity to generate electromagnetic force when the electromagnets are energized. The electromagnetic force attracts the valve core so that the connection between the airflow input channel 31 and the airflow output channel 33 is in an "open" state.

[0044] Therefore, designing the airflow control switch 32 as a structure including a sealed cavity, a valve core, and electromagnets arranged on both sides has the following technical advantages:

[0045] (1) By energizing and de-energizing the electromagnet, the movement of the valve core can be quickly controlled, thereby realizing the rapid switching between the airflow input channel 31 and the airflow output channel 33. This design makes the system's airflow control very precise, and can quickly open or close the airflow channel as needed.

[0046] (2) The mechanical structure composed of electromagnet and valve core is simple and reliable. Due to the characteristics of electromagnetic force, the valve core has stable and repeatable operation. This design enables the airflow control switch 32 to maintain high reliability during long-term use.

[0047] (3) When airflow is not needed, simply stopping the energization of the electromagnet will close the airflow channel, thus saving energy. In addition, the energy consumption of the electromagnet itself is relatively low, which helps to reduce the energy consumption of the entire system.

[0048] (4) Due to its relatively simple structure, the airflow control switch 32 is also relatively easy to maintain and replace. When a problem occurs, it can be quickly located and resolved, reducing production downtime.

[0049] Optionally, if there are multiple pigment tubes 1, the multiple pigment tubes 1 are divided into several groups. For each group of pigment tubes, one pigment tube 1 corresponds to one pigment drop cutting structure 3. Moreover, the multiple pigment drop cutting structures 3 corresponding to each group of pigment tubes share the same airflow input channel 31. Different pigment tubes 1 correspond to independent airflow output channels 33 and independent airflow control switches 32, so as to control the "on" or "off" of the corresponding pigment drop cutting structure 3 based on one airflow control switch 32.

[0050] Therefore, if there are multiple colorant tubes 1, and these colorant tubes 1 are divided into several groups, each group of colorant tubes is equipped with an independent airflow control switch 32 and an independent airflow output channel 33, but they share the same airflow input channel 31, the following technical advantages are available:

[0051] (1) Multiple colorant tubes 1 share the same airflow input channel 31, which can simplify the pipeline design of the system, reduce the number of required airflow sources, and thus reduce the overall complexity and cost of the system.

[0052] (2) The grouping design makes each group of pigment tubes and its corresponding pigment drop cutting structure 3 a relatively independent unit. This design facilitates group management and maintenance, and improves work efficiency.

[0053] (3) Each colorant tube 1 corresponds to an independent airflow control switch 32 and airflow output channel 33, enabling the system to control the colorant droplet cutting operation of each colorant tube 1 individually. This flexible control method can meet the different needs that may exist when different colorant tubes 1 are cutting.

[0054] (4) By independently controlling the color droplet cutting operation of each color tube 1, the system can ensure that the color droplet of each color tube 1 is cut off at the most appropriate time, thereby improving production efficiency and product quality.

[0055] Optionally, multiple pigment droplet cutting structures 3 are fixed side by side on a bracket in such a way that they are aligned with the pigment outlets of their respective pigment tubes 1.

[0056] Optionally, the pigment conveying system further includes a transition connection channel 34, one end of which is connected to the pigment outlet and the other end of which is connected to the pigment droplet cutting structure 3, so as to convey the airflow generated toward the pigment droplet to the pigment outlet and cut the pigment droplet.

[0057] Therefore, introducing a transitional connecting channel 34 into the pigment delivery system as a bridge connecting the pigment outlet and the pigment droplet cutting structure 3 has the following technical advantages:

[0058] The transition connection channel 34 ensures that the airflow generated from the pigment droplet cutting structure 3 is precisely guided to the pigment outlet, effectively cutting the pigment droplets that are about to be formed.

[0059] Through the design of the transition connection channel 34, the airflow can reach the pigment outlet more directly and quickly, thereby improving cutting efficiency, helping to reduce pigment droplet waste, and improving production efficiency and product quality.

[0060] Due to the precise guiding effect of the transition connection channel 34, the system can utilize airflow energy more effectively, reduce unnecessary energy loss, and help reduce system energy consumption and improve energy utilization efficiency.

[0061] The introduction of the transition connection channel 34 makes the structure of the colorant conveying system more compact and simplified, which not only facilitates the installation and maintenance of the system, but also helps to improve the stability and reliability of the system.

[0062] The design of the transition connection channel 34 can be adjusted and optimized according to actual needs to adapt to the requirements of different pigment outlets and pigment droplet cutting structures 3, making the system more adaptable and flexible, and able to adapt to a wider range of application scenarios.

[0063] Optionally, the pigment delivery system further includes: a pigment injection seat 35, which is disposed below the pigment tube 1 and communicates with the pigment outlet. The transition connection channel 34 communicates with the pigment injection seat 35 so that one end of it communicates with the pigment outlet. The pigment droplet leaves the pigment outlet and passes through the pigment injection seat 35 into the raw material mixing chamber pre-loaded with base material.

[0064] Therefore, introducing a colorant injection station 35 into the colorant delivery system and connecting it to the transition connection channel 34 and the colorant outlet has the following technical advantages:

[0065] The pigment ejector 35 is designed to provide an optimized transport path, ensuring that pigment droplets enter the raw material mixing chamber smoothly and accurately after exiting the pigment outlet. This design reduces the risk of pigment droplet loss and contamination during transport.

[0066] The structural design of the pigment injection holder 35 further enhances the guidance of pigment droplets, ensuring that the droplets enter the raw material mixing chamber along a predetermined trajectory. This is particularly important for applications requiring precise control of the position and distribution of pigment droplets.

[0067] Enhancing the spraying effect of pigment droplets: Airflow is supplied to the pigment spraying station 35 through the transition connecting channel 34, which generates a certain spraying force, helping the pigment droplets to better detach from the pigment outlet and enter the raw material mixing chamber. This spraying effect helps to improve the mixing effect of pigment droplets and product quality.

[0068] The introduction of the pigment injection unit 35 makes the structure of the pigment delivery system more compact and simplified. This not only facilitates system installation and maintenance but also helps to improve the system's stability and reliability.

[0069] The optimized pigment droplet transport path and spraying effect can improve the system's production efficiency. Pigment droplets can enter the raw material mixing chamber more quickly and accurately, thereby reducing waiting time and resource waste during the production process.

[0070] The pigment injection holder 35 can be designed and adjusted to meet different application requirements. For example, its shape, size, or position can be adjusted to accommodate the requirements of different pigment outlets and raw material mixing chambers. This flexibility allows the system to adapt to a wider range of application scenarios.

[0071] Optionally, if there are multiple pigment tubes 1, each pigment tube 1 corresponds to a pigment spraying seat 35, and multiple pigment spraying seats 35 are connected to form an integrated pigment spraying seat structure, which is located below the multiple pigment tubes 1.

[0072] Optionally, the colorant tube 1 includes an upper tube body 11, an intermediate tube body 12, and a lower tube body 13. The upper tube body 11 is connected to the intermediate tube body 12, and the intermediate tube body 12 is connected to the lower tube body 13 to form a cavity for accommodating the colorant 14.

[0073] Optionally, the outer wall of the upper tube 11 is connected to a driving device 16 via a transmission mechanism 15, and a lead screw 11 is provided in the upper tube 11. A pressure plate 112 meshes with the lead screw 11, so that when the driving device 16 drives the upper tube 11 to rotate via the transmission mechanism 15, the upper tube 11 drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the pressure plate 112 to press down, so as to push the pigment 14 in the cavity toward the lower tube 13 until pigment 14 can flow out of the lower tube 13.

[0074] like Figures 5A-10B As shown, the pigment tube may include: an upper tube body 11, an intermediate tube body 12, and a lower tube body 13. The upper tube body 11 is connected to the intermediate tube body 12, and the intermediate tube body 12 is connected to the lower tube body 13 to form a cavity for accommodating pigment 14. The outer wall of the upper tube body 11 is connected to a driving device 16 through a transmission mechanism 15, and a lead screw 111 is provided in the upper tube body 11. A pressure plate 112 is engaged on the lead screw 111. When the driving device 16 drives the upper tube body 11 to rotate through the transmission mechanism 15, the upper tube body 11 drives the lead screw 111 to rotate. The rotation of the lead screw 111 drives the pressure plate 112 to press down, so as to push the pigment 14 in the cavity toward the lower tube body 13 until pigment 14 can flow out of the lower tube body 13.

[0075] In this embodiment, the meshing design of the lead screw 11 and the pressure plate 112 allows the lead screw 11 to rotate and drive the pressure plate 112 to press down when the drive device 16 drives the upper tube 11 to rotate via the transmission mechanism 15. This mechanical structure ensures that the pigment 14 can be accurately and stably pushed to the lower tube 13, achieving precise pigment distribution. By controlling the rotation speed and direction of the drive device 16, the flow rate and direction of the pigment can be further controlled to meet different usage requirements. The upper tube 11 is connected to the drive device 16 via the transmission mechanism 15, enabling the entire pigment distribution process to be automated by controlling the drive device 16, greatly improving the convenience and efficiency of operation. The docking design between the upper tube 11, the middle tube 12, and the lower tube 13 ensures the structural stability and sealing of the pigment tube 1, avoiding pigment leakage or contamination. At the same time, the selection and configuration of the transmission mechanism 15 and the drive device 16 also consider the reliability and durability of the equipment, ensuring that the pigment tube 1 can operate stably for a long time.

[0076] Optionally, the upper end of the upper tube 11 is provided with a toothed protrusion 113 on its outer wall. The transmission mechanism 15 includes a transmission sleeve 151 and a helical gear 152. The transmission sleeve 151 is provided with a groove 1511. The transmission sleeve 151 engages with the toothed protrusion 113 on the upper tube 11. The helical gear 152 meshes with the transmission sleeve 151. The driving device 16 is connected to the helical gear 152 so that the driving device 16 drives the helical gear 152 to rotate. The rotation of the helical gear 152 drives the transmission sleeve 151 to rotate. The rotation of the transmission sleeve 151 drives the upper tube 11 to rotate, thereby driving the lead screw 111 to rotate.

[0077] The colorant pushing structure 2 in the above embodiments may include the lead screw 111 and the pressure plate 112. Of course, in some embodiments, it may also include the transmission mechanism 15 and the driving device 16. The specific structure design can determine the specific structure, but as long as the function of this application is achieved, it is acceptable.

[0078] Therefore, the transmission mechanism 15, which incorporates the convex tooth 113, the transmission sleeve 151, and the helical gear 152 in the above-mentioned colorant tube 1 design, has the following technical advantages:

[0079] (1) The engagement design between the protruding tooth 113 and the groove 511 on the transmission sleeve 151 ensures the precise connection and transmission between the upper tube body 11 and the transmission sleeve 151. This design avoids slippage or error during transmission and ensures the precise distribution of the pigment 14.

[0080] (12) The meshing design of the helical gear 152 and the transmission sleeve 151, as well as the connection between the helical gear 152 and the drive device 16, constitute a highly efficient power transmission system. This design enables the power of the drive device 16 to be transmitted quickly and accurately to the upper tube 11, thereby driving the lead screw 11 to rotate and realize the propulsion of the pigment.

[0081] (3) The integrated design of the convex tooth 113, the transmission sleeve 151 and the helical gear 152 makes the entire transmission mechanism 15 compact and space-saving. This is very important for the overall design of the colorant tube 1, as it helps to reduce the size and weight of the equipment and improve its portability and flexibility.

[0082] (4) The rotation of the helical gear 152 drives the transmission sleeve 151 to rotate, which in turn drives the upper tube body 11 to rotate. This transmission method has the characteristics of stability and reliability, which can ensure that the transmission mechanism 15 can still maintain stable performance during long-term and high-frequency use, and will not loosen or malfunction.

[0083] (5) Since the structure of the transmission mechanism 15 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.

[0084] 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 11, and the top of the lead screw seat 111 engages with the top of the upper tube 11 to fix the lead screw seat 111 in the inner cavity of the upper tube 11, so that the lead screw 11 can be driven to rotate synchronously when the upper tube 11 rotates.

[0085] Therefore, in the design of the colorant tube 1, the lead screw 11 is fixed in the inner cavity of the upper tube body 11 by the lead screw seat 111, which has the following technical advantages:

[0086] (1) The lead screw seat 111 stably fixes the lead screw 11 in the inner cavity of the upper tube 11. When the upper tube 11 is driven to rotate, the lead screw 11 can rotate synchronously and stably. This design ensures that the pigment 14 can be pushed continuously and smoothly, avoiding the possible stagnation or unevenness of the pigment during the pushing process.

[0087] (2) The top of the lead screw seat 111 is locked and fixed to the top of the upper tube body 11. This design makes the installation and removal 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.

[0088] (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.

[0089] (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 colorant distribution process.

[0090] Optionally, the drive device 16 includes a motor 161, a power output frame 162, and a power output shaft 163. The motor 161 is connected to the power output frame 162 to drive the power output frame 162 to rotate. The power output shaft 163 is connected to the power output frame 162 to drive the power output shaft 163 to rotate through the rotation of the power output frame 162. A helical gear 152 is sleeved on the power output shaft 163 to drive the helical gear 152 to rotate through the rotation of the power output shaft 163. The rotation of the helical gear 152 drives the transmission sleeve 151 to rotate.

[0091] Therefore, in the design of the colorant tube 1, a drive device 16, including a motor 161, a power output frame 162, and a power output shaft 163, is introduced to drive the helical gear 152 and the transmission sleeve 151, thereby driving the upper tube body 11 and the lead screw 11 to rotate. This has the following technical advantages:

[0092] (1) The motor 161 serves as a power source and can output power stably and efficiently. Through the transmission of the power output frame 162 and the power output shaft 163, the power can be transmitted to the helical gear 152 without loss, thereby ensuring the rapid and precise rotation of the transmission mechanism 15 and the upper tube 11.

[0093] (2) Motor 161 usually has a speed regulation function, which can precisely control the speed and direction of rotation. This allows the pushing speed of pigment 14 to be adjusted as needed, so as to achieve precise pigment distribution.

[0094] (3) Using motor 161 as a power source, the pigment distribution process can be automated. Users only need to set the corresponding parameters, and the equipment can automatically complete the pushing and distribution of pigments, reducing the difficulty and labor intensity of manual operation.

[0095] (4) The combination of motor 161, power take-off frame 162, and power take-off shaft 163 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.

[0096] (5) The relative independence of the motor 161 and the transmission mechanism 15 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.

[0097] Optionally, the lower tube 13 includes a nozzle 131 and a locking cap 132. The nozzle 131 is connected to the intermediate tube 12 so that the pigment 14 can be pushed outside the pigment tube 1. The locking cap 132 is used to lock the connection when the nozzle 131 is connected to the intermediate tube 12.

[0098] Therefore, in the design of the colorant tube 1, the lower tube body 13, including the nozzle 131 and the locking cap 132, has the following technical advantages:

[0099] (1) The nozzle 131 is directly connected to the intermediate tube 12, so that the pigment 14 can be smoothly pushed from the pigment tube 1 to the outside. This design simplifies the pigment distribution process and improves the ease of operation.

[0100] (2) The locking cap 132 provides a locking function when the nozzle 131 is connected to the intermediate tube 12, effectively preventing waste or contamination caused by accidental leakage of pigment during transportation or storage. This design increases the safety and reliability of the pigment tube 1.

[0101] (3) The locking cover 132 not only prevents pigment leakage, but also protects the nozzle 131 from external environmental corrosion, such as dust and moisture, when pigment is not in use, thereby extending the service life of the nozzle.

[0102] (4) The design of the locking cover 132 allows the nozzle 131 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.

[0103] (5) The combined design of nozzle 131 and locking cap 132 makes the pigment tube 1 more user-friendly and improves the user's operating experience and satisfaction. Users can easily control the distribution of pigment according to their own needs without worrying about pigment leakage or nozzle damage.

[0104] Alternatively, for example, the nozzle 131 may be connected to the intermediate tube 12 via a collar 133.

[0105] Optionally, the lower tube body 13 further includes a locking spring 133, which is engaged on the outer wall of the locking cover 132 when the locking cover 132 locks the connection to perform a locking process on the locking cover 132.

[0106] Therefore, in the design of the colorant tube 1, the introduction of a locking spring 133 into the lower tube body 13 has the following technical advantages:

[0107] (1) When the locking cover 132 locks the connection between the nozzle 131 and the intermediate tube 12, the locking spring 133 can be stably locked on the outer wall of the locking cover 132, ensuring that the connection between the locking cover 132 and the colorant tube 1 is tight and firm. This design effectively prevents the colorant leakage problem caused by accidental loosening and improves the safety and reliability of the colorant tube 1.

[0108] (2) The use of the locking spring 133 makes the locking operation of the latch cover 132 simpler and faster. The user only needs to align the latch cover 132 with the nozzle 131 and rotate it, and the locking spring 133 will automatically snap into the outer wall of the latch cover 132 to complete the locking process. This design reduces the user's operation steps and time, and improves the efficiency of use.

[0109] (3) The locking spring 133 is usually made of elastic material, such as stainless steel or spring steel, which has good wear resistance and corrosion resistance. This design enables the locking spring 133 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 colorant tube 1.

[0110] (4) The design of the locking spring 133 enables the colorant tube 1 to adapt to different working environments and conditions. Whether in high temperature, low temperature or humid environment, the locking spring 133 can maintain a stable locking effect, ensuring that the colorant tube 1 can work normally in various environments.

[0111] (5) Because the locking spring 133 is simple in design and easy to replace, when the locking spring 133 is damaged or worn, the user can easily remove it and replace it with a new locking spring 133 without disassembling or repairing the entire color tube 1. This design reduces the maintenance cost and difficulty of the color tube 1.

[0112] Optionally, the lower tube 13 further includes an anti-backflow structure 134, which is disposed in the nozzle 131. When the pigment 14 is to be pushed outside the pigment tube 1, the anti-backflow device is closed so that the pigment 14 can be pushed outside the pigment tube 1. When the pushing of the pigment 14 outside the pigment tube 1 is to be stopped, the anti-backflow device is opened so that the pigment 14 is sealed inside the pigment tube 1.

[0113] Therefore, the anti-backflow structure 134 included in the lower tube body 13 plays a key role in the design of the colorant tube 1, and has the following technical advantages:

[0114] (1) The anti-backflow structure 134 in the nozzle 131 ensures that when the pigment 14 is stopped from being pushed to the outside of the pigment tube 1, the pigment will not flow back into the tube due to gravity or other reasons. This function is crucial in keeping the inside of the pigment tube 1 clean and preventing pigment contamination.

[0115] (2) When it is necessary to push the pigment 14 to the outside of the pigment tube 1, the anti-backflow device is closed, allowing the pigment to flow out smoothly. This design simplifies the operation process and improves work efficiency.

[0116] (3) By effectively preventing pigment backflow, the anti-backflow structure 134 reduces pigment waste and avoids pipe contamination and pigment cross-contamination that may be caused by backflow.

[0117] (4) The anti-backflow structure 134, as part of the design of the colorant tube 1, increases the stability and reliability of the entire device. Its precise design and reliable performance ensure the stable operation of the colorant tube 1 under various working conditions.

[0118] (5) The design of the anti-backflow structure 134 enables it to adapt to different application scenarios, including those requiring precise control of pigment flow and prevention of backflow. This flexibility has led to the widespread use of pigment tube 1 in multiple industries.

[0119] (6) The anti-backflow structure 134 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 color tube 1.

[0120] Optionally, the anti-backflow structure 134 includes a ball 1341 and a spring 1342 located in the nozzle 131. The spring 1342 presses against the ball 1341. When the pigment 14 is to be pushed out of the pigment tube 1, the spring 1342 is squeezed, causing the ball 1341 to open the nozzle 131 so that the pigment 14 can be pushed out of the pigment tube 1. When the pushing of the pigment 14 out of the pigment tube 1 is to be stopped, the spring 1342 returns to its original position, causing the ball 1341 to block the nozzle 131 so that the pigment 14 is blocked inside the pigment tube 1.

[0121] Therefore, the anti-backflow structure 134, composed of a ball 1341 and a spring 1342, has the following technical advantages in the design of the colorant tube 1:

[0122] (1) A simple and efficient anti-backflow mechanism is achieved by combining the ball 1341 and the spring 1342. When the pigment 14 is pushed, the ball 1341 is pushed open to allow the pigment to pass through; when the pushing stops, the ball 1341 quickly resets under the action of the spring 1342, blocking the nozzle 131 and effectively preventing pigment backflow.

[0123] (2) Because the anti-backflow structure 134 can quickly and accurately control the flow of pigment, it helps to improve the accuracy of pigment dispensing. This structure provides reliable performance in applications such as precision coating, dispensing, or other applications that require precise control of pigment quantity.

[0124] (3) By preventing pigment backflow, the accumulation and sedimentation of pigment in the pipeline are reduced, thereby reducing the risk of pipeline blockage. This helps to keep pigment pipe 1 unobstructed and extend the service life of the equipment.

[0125] (4) Effectively preventing pigment backflow means reducing pigment waste caused by backflow. At the same time, it avoids pipeline contamination and pigment cross-contamination that may be caused by pigment backflow, maintaining the purity and consistency of pigment.

[0126] (5) The anti-backflow structure composed of ball 1341 and spring 1342 is relatively simple and easy to disassemble and clean. When replacement or cleaning is required, the user can easily complete these operations to keep the equipment in good condition.

[0127] (6) This anti-backflow structure is suitable for a variety of different types of pigments and working environments. Whether it is a viscous liquid, powder, or other type of material, as long as the appropriate ball 1341 and spring 1342 are selected, an effective anti-backflow function can be achieved.

[0128] Based on the above embodiments, considering that the tube body can be an integral structure, a colorant conveying system is provided, which includes: a tube body, a lead screw 11, and a pressure plate 112. The tube body has a cavity for accommodating colorant 14. The outer wall of the tube body is connected to a driving device 16 through a transmission mechanism 15. The lead screw 11 is disposed in the tube body, and the pressure plate 112 is engaged on the lead screw 11. When the driving device 16 drives the tube body to rotate through the transmission mechanism 15, the tube body drives the lead screw 11 to rotate. The rotation of the lead screw 11 drives the pressure plate 112 to press down, so as to push the colorant 14 in the cavity toward the outside of the tube body until it forms colorant 14 that can flow out of the tube body.

[0129] Based on the above embodiments, a lipstick machine is provided, which includes the pigment delivery system described in any embodiment of this application, wherein the pigments in each pigment tube 1 are of different colors, and the pigments in multiple pigment tubes 1 can be mixed to obtain the desired lipstick color.
