Description

Technical Field

[0001] This invention relates to the field of hair dyeing equipment technology, specifically to an automatic hair dyeing device. Background Technology

[0002] Currently, most hair dyeing devices on the market use electric or manual methods to dispense hair dye from a container and apply it to the hair with the help of brush bristles or comb teeth. Common solutions include hair dye combs with built-in micro-pumps or hair dye brushes with vibrating functions, which aim to promote the release of hair dye through mechanical vibration or squeezing during the application process. These technologies have improved the convenience of hair dyeing to a certain extent, realizing the functions of dispensing and applying hair dye;

[0003] However, in the process of applying hair dye, existing hair dyeing devices often apply the dye directly to the hair section through the bristles or comb teeth. This can easily lead to uneven distribution of the dye among the hair strands, resulting in areas that are too dark or missed areas, which affects the dyeing efficiency and uniformity. At the same time, because the bristle structure has strong adhesion to the dye, it not only causes dye residue to be wasted in the gaps between the bristles, but also makes the cleaning work after use cumbersome and difficult, limiting the improvement of the user experience.

The control circuit board is electrically connected to the micro pump to adjust the output power of the micro pump. The battery is electrically connected to the micro pump through the control circuit board to supply power to the micro pump. The display screen is electrically connected to the battery and the control circuit board respectively.

[0011] Preferably, the middle section of the outer shell is provided with a protruding wiring groove for accommodating the wiring of the sensing circuit board, and the wiring groove extends from the front end of the liquid storage section to the rear end.

The inner rear end of the quick-release button abuts against a spring, and is used to reset after inward elastic deformation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention integrates the hair dyeing section, the liquid storage section, and the pumping section. By controlling the micro pump through the control circuit board, fully automatic dispensing of the dye can be achieved. Furthermore, by linking the start and stop control of the micro pump with the clamping action of the hair dyer, dispensing is triggered when the clamp is closed and stopped when the clamp is opened, which significantly simplifies the operation steps and enhances the intelligence of the product.

[0016] 2. This invention forms an immersion cavity in the hair dyeing section to accommodate the hair section, allowing the hair section to be completely wrapped and immersed in the hair dye. At the same time, the built-in vibration mechanism drives the hair dye to fully mix and contact with the hair section. This effectively avoids the problem of uneven distribution of hair dye among the hair strands, significantly improving the coloring uniformity and coloring effect.

This ensures that the hair dye is evenly applied to the hair section, reducing waste and making cleaning easier and faster.

[0018] 4. This invention integrates a start-stop control structure into the hair dyeing section, which automatically starts the delivery of hair dye while the user is picking up the hair section and immediately stops it when the hair is released. This ensures the continuity and smoothness of the operation, avoids the problem of continuous overflow and waste of hair dye caused by forgetting to turn off the switch, and also improves the safety and convenience of use.

[0019] 5. This invention significantly improves space utilization efficiency by integrating the pumping mechanism and the paste storage mechanism in a coaxial manner. Furthermore, by using a micro-pump to pump the hair dye paste, the whole machine can accommodate a larger volume paste storage tank while maintaining a compact shape. In addition, the integrated coaxial layout simplifies the internal piping, optimizes the smoothness of the pumping path and the structural strength, thereby achieving a more stable and controllable paste dispensing process and improving the reliability and durability of the equipment in long-term use.

[0020] 6. This invention arranges the dyeing section, liquid storage section, and pumping section linearly along the front, middle, and rear to form an overall configuration with reasonable functional zoning and extended contours. This effectively optimizes the distribution of the equipment's center of gravity and the balance of the grip, allowing the liquid storage section and the pumping section to work together as a stable handheld part. Users can hold the device firmly with one hand, and the handle on the front side allows for easy control of the clamp opening and closing. This significantly improves operational comfort and stability, reduces hand fatigue, and achieves a balance between functional integration and ease of operation. Attached Figure Description

[0022] The diagram shows: Detailed Implementation

[0023] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0024] This invention discloses an automatic hair dyeing device. By forming an immersion cavity in the hair dyeing section to accommodate hair sections, the hair sections are completely coated and saturated with hair dye. Simultaneously, a built-in vibration mechanism drives the hair dye to fully mix and contact with the hair sections. This effectively avoids the problem of uneven distribution of hair dye among the hair strands, significantly improving color uniformity and coloring effect. Furthermore, this invention, through fully automatic operation, makes the hair dyeing process more convenient and significantly reduces the difficulty of the process. Moreover, by controlling a micro-pump via a control circuit board, fully automatic dye dispensing is achieved. By linking the start and stop control of the micro-pump with the clamping action of the hair dyeing device, dye dispensing is triggered when the clamp is closed and stopped when it is opened, significantly simplifying the operation steps and significantly improving the product's intelligence.

[0025] Example 1 This embodiment discloses an automatic hair dyeing device, such as Figure 1 , Figure 2 As shown, the device includes a hair dyeing section 300, a liquid storage section 200, and a pumping section 100. The pumping section 100 pumps the hair dye cream from the liquid storage section 200 to the hair dyeing section 300. The hair dyeing section 300 includes a front outer shell 19 and a front upper cover 24 that are arranged to open and close relative to each other. The front end of the front outer shell 19 has a discharge structure 25 that communicates with the liquid storage section 200. A vibration mechanism is installed inside the immersion chamber, preferably mounted on the front upper cover 24. The rear end of the front outer shell 19 is fixedly connected to the liquid storage section 200, and the rear end of the front upper cover 24 is hinged to the rear end of the front outer shell 19. The discharge structure 25 forms an immersion chamber with the front upper cover 24. During hair dyeing, the hair section is located in the immersion chamber and comes into contact with the hair dye cream inside the immersion chamber. The vibration mechanism vibrates to immerse the hair section in the hair dye cream.

[0026] In use, the hairpiece is placed on the front discharge structure 25, and the front outer shell 19 and the front top cover 24 are closed, placing the hairpiece in the enclosed immersion chamber. At this time, the pumping mechanism in the pumping section 100 operates, pumping the hair dye cream located in the middle liquid storage section 200 into the front immersion chamber. Simultaneously, the vibration mechanism activates high-speed vibration, ensuring the hairpiece is thoroughly mixed with the hair dye cream under the action of high-speed vibration. This hair dyer can achieve fully automatic operation, automatically and evenly applying the dye cream to the hair, eliminating the need for users to repeatedly apply dye, brush, and rub the hair. This not only saves time and ensures even dyeing but also avoids dye cream waste. Furthermore, the synergistic effect of the closed immersion chamber and the vibration mechanism significantly improves the evenness of dyeing, effectively avoiding the problems of uneven dyeing and dye cream waste caused by direct contact between the dye comb and hair in traditional hair dyeing methods. The hair dyer disclosed in this embodiment makes hair dyeing operations more convenient and significantly reduces the difficulty of the dyeing process.

[0027] Example 2 This embodiment, as a preferred example of Embodiment 1, specifically describes the structure of the hair dyeing section 300, such as... Figure 4 , Figure 5 As shown, the front end of the front shell 19 is provided with a discharge structure 25, which is connected to the external hair dye container and is used to discharge hair dye. The discharge structure 25 and the front cover 24 form an openable and closable immersion chamber for accommodating hair sections. A motor 22 is installed inside the front cover 24. A vibrating element 21, opposite to the discharge structure 25, is coaxially mounted on the output shaft of the motor 22 to transmit vibration to the hair sections and the hair dye inside the immersion chamber. A roller 20 is provided inside the front cover 24, located on the side of the vibrating element 21, to allow the hair sections to adhere to the upper surface of the discharge structure 25. The roller 20 is located on the side of the vibrating element 21 closer to the hair section outlet, and extends at least from the front end to the rear end of the immersion chamber. This facilitates the adhesion of the hair sections during hair dye application and also removes excess dye from the hair sections.

[0028] The vibrating component 21 includes a vibrating needle, a vibrating plate, and other structures. The vibrating plate has a symmetrical structure, with a striking part extending from at least the front end to the rear end of the impregnation chamber on both sides. This striking part, driven by the motor 22, transmits vibration to the hair strands, ensuring that all hair strands in the impregnation chamber are evenly struck during operation, preventing any omissions and further improving the uniformity of the dyeing process. The discharge structure 25 has multiple discharge holes arranged in a row, extending from at least the front end to the rear end of the impregnation chamber. These discharge holes are connected to the internal cavity of the discharge structure 25. This row of discharge holes ensures that all hair strands in the impregnation chamber are mixed with the dye, further improving the uniformity of the dyeing process.

[0029] Furthermore, the rear end of the discharge structure 25 is provided with an inlet communicating with the internal cavity of the discharge structure 25. The inlet is connected to the external hair dye container via a flexible hose. The motor 22 is mounted inside the front cover 24 via a motor mounting bracket 23. When the front outer shell 19 and the front cover 24 are closed, there is a gap between the motor mounting bracket 23 and the front outer shell 19. The flexible hose passes through the gap between the motor mounting bracket 23 and the inner wall of the front outer shell 19 and extends to the rear end of the front outer shell 19. Through the above design, the motor 22 and the hair dye delivery pipeline can be rationally arranged within a limited space.

[0030] Furthermore, the discharge structure 25 has a hair section inlet side and a hair section outlet side on both sides perpendicular to the direction of hair section movement. The hair section inlet side is provided with a notch for the hair section to enter the impregnation chamber, and the hair section outlet side is provided with a comb tooth structure. The comb tooth structure includes multiple comb tooth structures arranged in parallel, with the multiple comb tooth structures arranged at least from the front end to the rear end of the impregnation chamber. During hair dyeing, the hair section enters the impregnation chamber through the notch on the hair section inlet side and passes through the comb tooth structure on the hair section outlet side. The comb tooth structure is mainly used to fix the hair section, so that the hair section is evenly distributed in the impregnation chamber along the front-back direction, thereby improving the uniformity of hair dyeing.

[0031] Example 3 This embodiment, as a preferred example of Embodiment 1, specifically describes the structure of the liquid storage section 200 and the pumping section 100, such as... Figure 6 , Figure 7 As shown, the liquid storage section 200 includes a middle outer shell 17 and a liquid tank 14 coaxially installed inside the middle outer shell 17. The liquid tank 14 is used to store hair dye. The rear end of the liquid tank 14 is connected to the pumping section 100, and the front end of the liquid tank 14 is provided with a discharge port for connecting to an external hair dyeing mechanism. The pumping section 100 includes a rear shell and a micro pump disposed inside the rear shell. The front end of the micro pump is the actuator, used to drive the piston 13 inside the liquid tank 14 to move forward axially. In use, the micro pump operates, driving the piston 13 at the front end to move forward, thereby ensuring a stable dispensing of hair dye from the liquid tank 14. By integrating the pumping mechanism and the paste storage mechanism into a coaxial design, space utilization efficiency is significantly improved. This allows the machine to accommodate a larger paste storage tank while maintaining a compact shape. In addition, the integrated coaxial layout simplifies the internal piping, optimizes the smoothness of the pumping path and the structural strength, thereby achieving a more stable and controllable paste dispensing process and improving the reliability and durability of the equipment in long-term use. Furthermore, by adopting a micro pump, space is significantly saved compared to the traditional screw and nut type pumping mechanism, further improving the integration level.

[0032] Furthermore, the pumping section 100 also includes a tail cap 1, a battery 4, and a control circuit board 5. The tail cap 1 is installed at the rear end of the rear housing to seal it. The control circuit board 5 is located at the rear end of the micro pump to adjust its output power. The battery 4 is located at the rear end of the control circuit board 5 to power the micro pump. A display screen 2 is positioned between the tail cap 1 and the battery 4. The display screen 2 is electrically connected to both the battery 4 and the control circuit board 5. The display screen 2 shows information such as mode and time, and can be set to either a beginner mode or an advanced mode, which corresponds to the speed and intensity of the dispensing. Through the cooperation of the control circuit board 5 and the display screen 2 or other interactive devices, different dispensing levels of the hair dye can be achieved, thus meeting the needs of different users and making the process more user-friendly.

[0033] Furthermore, the rear housing is a cylindrical structure, and the display screen 2, battery 4, control circuit board 5, and micro pump are coaxially installed in the rear housing from back to front. The micro pump includes an air pump 7, and a liquid tank sealing cover 12 is provided at the rear end of the liquid tank 14. The liquid tank sealing cover 12 has a through hole in the middle that communicates with the air pump 7.

[0034] Example 4 This embodiment, as a preferred example of Embodiment 1, provides a detailed description of the start / stop control function and specific circuit structure of the hair dye device described above. Its structure is as follows: Figure 8 , Figure 9 As shown, the front housing 19 and the front top cover 24 are respectively provided with a first sensing area 26 and a second sensing area 27 at corresponding positions. One of the first sensing area 26 and the second sensing area 27 is equipped with a magnet, and the other of the first sensing area 26 and the second sensing area 27 is equipped with a sensing circuit board. The sensing circuit board is connected to the control circuit board 5 inside the pumping section 100 for controlling the operation of the pumping mechanism through a circuit, and is configured such that when the front housing 19 and the front top cover 24 are open, the pumping mechanism, specifically the air pump 7 and the motor 22, stops working; when the front housing 19 and the front top cover 24 are closed, the pumping mechanism, specifically the air pump 7 and the motor 22, works to pump the hair dye cream located in the liquid tank into the immersion chamber to perform the hair dyeing action. This embodiment links the start / stop control of the pumping mechanism with the clamping action of the hair dyer, triggering the dispensing of dye when the clamp is closed and stopping the dispensing when the clamp is opened. This significantly simplifies the operation, allowing the user to automatically start the dispensing of hair dye while clamping the hair section and immediately stop it when releasing it. This ensures the continuity and smoothness of the operation, avoids the problem of continuous overflow and waste of hair dye caused by forgetting to turn off the switch, and also improves the safety and convenience of use.

[0035] Furthermore, the middle section housing 17 is provided with a protruding wiring groove 28 for accommodating the wiring of the sensing circuit board. The wiring groove 28 extends from the front end to the rear end of the liquid storage section 200. A through hole is provided at the rear end of the front section housing 19, through which the wiring of the sensing circuit board extends to the outside of the front section housing 19 and into the wiring groove 28. A cable protection cover 16 is provided on the outer rear end of the middle section housing 17, and the rear end of the wiring groove 28 is located inside the cable protection cover 16. The wiring of the sensing circuit board extends from the wiring groove 28 into the cable protection cover 16, through the cable protection cover 16, into the rear section housing of the pumping section 100, and connects to the control circuit board 5. A contact circuit board 15 is provided inside the cable protection cover 16. The front side of the contact circuit board 15 is electrically connected to the wiring of the sensing circuit board, and a contact connector 8 is provided on the rear side of the contact circuit board 15, which is electrically connected to the control circuit board 5. The inner contour of the cable protection cover 16 matches the outer surface contour of the middle housing 17, and the cable protection cover 16 is fixedly mounted on the middle housing 17 with screws. The front housing 19 or the front top cover 24 has a sealed cable groove extending from the front end to the rear end, in which the wiring of the sensing circuit board is accommodated. This rational layout allows the wiring to extend reasonably within the housing without adding extra space and while ensuring sealing performance.

[0036] Example 5 This embodiment, as a preferred example of Embodiment 1, provides a specific description of the outer shell structure of the hair dyeing device described above. Its structure is as follows: Figure 2 , Figure 3 As shown, the pumping section 100 includes a cylindrical rear housing, and the liquid storage section 200 includes a cylindrical middle housing 17, which is coaxially mounted on the front end of the rear housing. The rear housing is a split structure, including a rear upper cover 3 and a rear lower cover 6, which together form a cylindrical rear housing. The rear end of the front upper cover 24 has an opening and closing handle 18 that passes through the front housing 19 and extends to the outside of the front housing 19. By arranging the dyeing section, liquid storage section, and pumping section linearly along the front, middle, and rear, an overall configuration with reasonable functional zoning and extended contours is formed, effectively optimizing the equipment's center of gravity distribution and grip balance. This allows the liquid storage section and pumping section to work together as a stable handheld part, enabling the user to hold the equipment securely with one hand. Furthermore, the rear end of the middle section housing 17 is detachably connected to the front end of the rear section housing via a quick-release button 10. The front end of the quick-release button 10 is engaged and fixed to the inner wall of the rear end of the middle section housing 17, and the rear end of the quick-release button 10 is used to engage with the front end of the rear section housing. The quick-release button 10 is an elastic element and is configured such that when the rear end of the quick-release button 10 is subjected to an inward radial force, it disengages from the front end of the rear section housing. The inner side of the rear end of the quick-release button 10 abuts against the spring 11 and is used to reset after inward elastic deformation. Through the above quick-release design, hair dye can be quickly added. When hair dye needs to be replenished, simply press the quick-release button 10 to quickly detach the middle section reservoir section 200 from the rear section pumping section 100, thereby achieving convenient dye addition.

[0037] Furthermore, the front housing 19 includes a front housing body, a connecting portion, and a first hinge portion. The connecting portion is circular in axial projection, matching the middle housing 17, and is coaxially fixedly installed at the front end of the middle housing 17. The front housing body is located at the edge of the connecting portion and extends in the front-rear direction. The first hinge portion is located on the front side of the connecting portion and is used to hinge with the second hinge portion at the rear end of the front cover 24. A through hole is provided at the rear end of the front housing body. The second hinge portion at the rear end of the front cover 24 extends radially outward, passes through the through hole at the rear end of the front housing body to reach the outside of the front housing 19, and then extends rearward to form an opening handle 18. The opening handle 18 is configured such that, when the front housing 19 and the front cover 24 are closed, the rear end of the opening handle 18 is located at the front side of the pumping section 100 in radial projection. The outer diameters of the middle section shell 17 and the rear section shell are the same. The front section shell 19 and the front top cover 24 are configured such that, in the closed state, the outer contours of the front section shell 19 and the front top cover 24 do not exceed the outer contours of the middle section shell 17 and the rear section shell in their axial projection. In this embodiment, by arranging the dyeing section, the liquid storage section, and the pumping section linearly along the front, middle, and rear, a comprehensive configuration with reasonable functional zoning and extended contours is formed. This effectively optimizes the distribution of the device's center of gravity and the balance of the grip, allowing the liquid storage section and the pumping section to work together as a stable handheld part. Users can hold the device firmly with one hand, and the handle on the front side allows for easy control of the clamp opening and closing, significantly improving operational comfort and stability, reducing hand fatigue, and simultaneously achieving a balance between functional integration and ease of operation.
