[0021] It should be understood that although various elements may be described in this disclosure with terms such as first, second, third, etc., these elements should not be limited to these terms. These terms are merely intended to distinguish elements of the same type from one another. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this disclosure.

[0022] As shown in FIG. 1, the hair dyeing tool of the present invention comprises a housing 1 having an air inlet 2 and an exhaust port 3, the air inlet 2 communicating with the exhaust port 3 to form an air duct 4, a negative pressure intake port 5 provided between the air inlet 2 and the exhaust port 3, the negative pressure intake port 5 communicating with the air duct 4 to form a negative pressure passage 6, a turbine 7 installed at the air inlet 2, a hair dyeing assembly including a dye container 8 and a dye nozzle 9 communicating with the dye container 8, the dye nozzle 9 being installed at the negative pressure intake port 5 of the housing 1, and an optical sensor 10 installed at the negative pressure intake port 5 of the housing 1. The negative pressure intake 5 is provided to suck in and straighten the hair, then the optical sensor 10 starts to detect the hair from the root, and when it detects gray hair, it triggers the hair dye nozzle to spray out hair dye to spray dye the gray hair, so that the user can spray dye the gray hair accurately, effectively reducing the amount of hair dye used, avoiding a large amount of hair dye coming into contact with the scalp, reducing the chance of the user becoming sensitive to the hair dye, saving the hair dyeing cost, reducing environmental pollution, and achieving a balance between maintaining hair health and making hair beautiful.

[0023] As shown in Figures 1 and 2, in order to enable the optical sensor 10 to detect hair more clearly and easily, a hair combing section 11 is provided extending outward from the negative pressure intake port 5 of the housing 1, the hair combing section 11 includes a number of comb teeth 12, and the optical sensor 10 is installed between two adjacent comb teeth 12. Therefore, by providing the comb teeth 12, the hair can be well arranged before detection, and at the time of detection, the comb teeth 12 can be combed to separate the hair, so that a large amount of the comb teeth 12 are not piled up together, which adversely affects the detection of hair by the optical sensor 10.

[0024] As shown in FIG. 3, in order to spray the dye evenly on the gray hair to be dyed, a hollow passage 13 for transporting the dye is provided inside the comb teeth 12, the hollow passage 13 communicates with the dye container 8, and the dye nozzle 9 is installed on the side wall of the comb teeth 12. When the optical sensor 10 detects the hair between two adjacent comb teeth 12 and finds a gray hair, the dye is transported through the hollow passage 13 to the dye nozzle 9 installed on the side wall of the comb teeth 12, and the hair between the two adjacent comb teeth 12 is sprayed evenly by the dye nozzle 9, thereby avoiding the occurrence of a situation in which the hair is sprayed unevenly.

[0025] As shown in FIG. 1, in order to assist the negative pressure intake port 5 in sucking in and straightening the hair, a number of rotating brush heads 14 are installed in parallel and facing each other between the negative pressure intake port 5 and the dye nozzle 9, and the rotating brush heads 14 are provided with brush teeth 15 and brush bristles 16. Therefore, when the negative pressure intake port 5 generates a negative pressure intake airflow to suck in the hair, the rotating brush heads 14 installed in parallel and facing each other can cooperate with each other to further pinch and straighten the hair, thereby avoiding the hair from loosening and falling out of the inside of the device, which adversely affects the detection and hair dyeing effect.

[0026] As shown in FIG. 1, the housing 1 further includes a handle 17, which is connected to the housing 1. The handle 17 includes therein a control circuit board and a switch and power supply assembly electrically connected to the control circuit board.

[0027] As shown in Figures 1 and 2, in order to prevent electrical equipment components inside the handle 17 from overheating and burning out, the handle 17 is provided with a heat dissipation hole 18, which communicates with the air duct 4 to form a heat dissipation passage 19. Therefore, by providing the heat dissipation hole 18 and the heat dissipation passage 19, the air flow inside the air duct 4 is utilized rationally, thereby realizing the heat dissipation function.

[0028] 1 and 2, in order to improve the dyeing accuracy and reduce the amount of dye used, the dye container 8 is installed on one side of the housing 1, and the dye container 8 is provided with a liquid supply pump 20, which is provided with a conveying pipe 21 so that each of the liquid supply pumps 20 is independently connected to the dye nozzle 9. Therefore, when the corresponding optical sensor 10 detects a gray hair, the liquid supply pump 20 is driven to supply liquid to the dye nozzle 9 corresponding to the optical sensor 10, and the dye nozzle 9 is controlled to spray the gray hair evenly, thereby achieving directional and effective hair dyeing.

[0029] As shown in Figs. 1 and 2, in order to accommodate users with long hair and to easily clean and organize the appliance, the housing 1 is installed in a cylindrical shape, and the negative pressure intake port 5 and the exhaust port 3 are installed opposite each other at both ends of the housing 1, so that the hair of a user with long hair can enter the inside of the appliance through the negative pressure intake port 5 and then exit through the exhaust port 3, making it suitable for normal use by users with long hair. At the same time, the negative pressure intake port 5 and the exhaust port 3 installed opposite each other have a straight path between them, making it easy to organize, and reducing the presence of hygienic blind spots such as bends inside the appliance.

[0030] As shown in FIGS. 1 and 2, the housing 1 is provided with an intake filter net 22 at the intake port 2 to prevent impurities such as dust from entering the inside of the turbine 7 and adversely affecting normal operation.

[0031] As shown in FIG. 1, in order to prevent the user's hair from getting caught in the turbine 7, the housing 1 is provided with a protective net 23 at the exhaust end of the turbine 7. Thus, by providing the protective net 23, the turbine 7 is partitioned, thereby preventing the user's hair from getting caught in the turbine 7.

[0032] As shown in Figure 4, the operating principle is as follows: First, the turbine 7 is started to make the outside wind flow quickly from the air inlet 2 to the air outlet 3 to form a high-speed airflow in the air duct 4, and when the air duct 4 forms a high-speed airflow, the flow velocity at the negative pressure intake port 5 is small, so a negative pressure is formed at the negative pressure intake port 5 to suck the user's hair into the inside of the appliance and straighten it.

[0033] For the sucked and straightened hair, the hair roots can be easily and clearly seen by the optical sensor 10, the optical sensor 10 detects the hair, and due to the different light transmittance / light refractive index between white hair and black hair, the optical sensor 10 can effectively identify the white hair, and when the optical sensor 10 detects the white hair, it will trigger the hair dye nozzle to spray the white hair evenly.

[0034] The above description is merely a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure, as long as they achieve the technical effect of the present invention by the same means, should be included in the protection scope of the present disclosure. They all belong to the protection scope of the present invention. Within the protection scope of the present invention, the technical solution and / or the embodiment may undergo various different modifications and changes. [Explanation of symbols]
