[0022] As in Fig. 1, the utility model provides a hair coloring device comprising a housing 1, wherein the housing 1 is provided with an air inlet 2 and an air outlet 3, the air inlet 2 is connected to the air outlet 3 to form an air duct 4, wherein the housing 1 is provided with a vacuum exhaust opening 5 between the air inlet 2 and the air outlet 3, the vacuum exhaust opening 5 is connected to the air duct 4 to form a vacuum duct 6; a turbine 7, wherein the turbine 7 is provided at the air inlet 2; a hair coloring assembly, wherein the hair coloring assembly comprises a dye container 8 and dye nozzles 9 connected to the dye container 8, wherein the dye nozzle 9 is provided at the vacuum exhaust opening 5 of the housing 1; and light sensors 10, wherein the light sensors 10 are provided at the vacuum exhaust opening 5 of the housing 1.The hair is drawn in and straightened through the negative pressure exhaust port 5, and then the hair is detected from the hair root by the light sensor 10, and the dye nozzle is triggered to spray hair dye onto the gray hair when the gray hair is detected, so that the user can accurately spray and dye the gray hair and effectively reduce the amount of hair dye used, thereby avoiding a large amount of hair dye coming into contact with the scalp and reducing the possibility of the user being allergic to the hair dye, saving the cost of hair dyeing while reducing environmental pollution, maintaining a balance between hair health and beauty.

[0023] As in the Fig. 1 to 2, the vacuum exhaust port 5 of the housing 1 is provided with an outwardly extending comb 11 to enable the light sensor 10 to better and more easily detect hair. The comb 11 includes a plurality of comb teeth 12, and the light sensor 10 is provided between two adjacent comb teeth 12. Therefore, the hair can be neatly combed by the comb teeth 12 before detection, and at the same time, during detection, the comb teeth 12 are able to separate the hair, so that the hair is not piled up in a large number of piles, which does not affect the light sensor 10 in detecting the hair.

[0024] As in Fig. 3, the comb teeth 12 are provided internally with hollow channels 13 for conveying hair dye so that the dye can be evenly applied to the gray hair to be dyed, the hollow channels 13 being connected to the dye container 8, and the dye nozzles 9 being provided on the side walls of the comb teeth 12; when the light sensor 10 has detected gray hair between two adjacent comb teeth 12, the dye is guided through the hollow channels 13 to the dye nozzle 9 provided on the side wall of the comb teeth 12, and the hair between the two adjacent comb teeth 12 is evenly sprayed by the dye nozzle 9, thereby avoiding uneven spraying of the hair.

[0025] As in Fig. 1, a plurality of rotating brush heads 14 are also provided in parallel and opposite to each other between the vacuum vent 5 and the dye nozzle 9 to assist the vacuum vent 5 in drawing in and straightening the hair, the rotating brush heads 14 being provided with brush teeth 15 and bristles 16; thus, when the vacuum vent 5 generates a negative pressure airflow to draw in the hair, the parallel arranged rotating brush heads 14 are able to cooperate to further clamp and straighten the hair, thereby preventing the hair from becoming loose inside the device and impairing the effect of detection and hair coloring.

[0026] As in Fig. 1, it further comprises a handle 17, wherein the handle 17 is connected to the housing 1, the handle 17 is provided inside with a control board, a switch connected to the control board and a power supply unit.

[0027] As in the Fig. 1 and Fig. 2, the handle 17 is provided with heat dissipation holes 18 to prevent overheating and burning of the electrical components inside the handle 17, and the heat dissipation holes 18 are connected to the air duct 4 to form a heat dissipation duct 19; therefore, by providing the heat dissipation holes 18 and the heat dissipation duct 19, the airflow inside the air duct 4 is effectively utilized to realize the function of heat dissipation.

[0028] As in the Fig. 1 and Fig. As shown in Fig. 2, in order to improve the precision of hair dyeing and reduce the consumption of hair dye, the dye tank 8 is provided on one side of the housing 1. The dye tank 8 is provided with a liquid supply pump 20. The liquid supply pump 20 is connected to the dye nozzles 9 individually and separately via a delivery pipe 21 provided therewith. Thus, when the corresponding light sensor 10 detects gray hair, the liquid supply pump 20 is driven to supply liquid to the dye nozzle 9 corresponding to the light sensor 10, and the dye nozzle 9 is controlled to spray evenly onto the gray hair to achieve effective targeted hair dyeing.

[0029] As in the Fig. 1 and Fig. 2, the casing 1 is shaped like a cylinder to accommodate users with long hair and facilitate cleaning of the device, and the negative pressure exhaust port 5 and the air outlet 3 are arranged opposite each other at both ends of the casing 1; therefore, the hair of a user with long hair can enter the interior of the device through the negative pressure exhaust port 5 and then exit through the air outlet 3, thereby adapting it to the normal use of a user with long hair; at the same time, the relatively arranged negative pressure exhaust port 5 and the air outlet 3 can be easily cleaned due to the straight channel between them, thereby reducing hygienic dead spaces such as corners inside the device.

[0030] As in the Fig. 1 and Fig. 2, the casing 1 is provided with an air inlet filter 22 at the air inlet 2 to prevent dust and other contaminants from entering the turbine 7 and impairing its normal operation.

[0031] As in Fig. 1, the housing 1 is provided with a protective grid 23 at the outlet end of the turbine 7 to prevent the user's hair from being drawn into the turbine 7, so that the turbine 7 is separated by the provision of the protective grid 23 and thus prevents the user's hair from being drawn into the turbine 7.

[0032] As in Fig.4, the working principle is as follows: First, the turbine 7 is started, so that the air from the outside flows quickly from the air inlet 2 to the air outlet 3 to form a fast airflow in the air duct 4, and when the air duct 4 forms a fast airflow, a negative pressure is formed at the negative pressure exhaust port 5 due to the low flow rate at the negative pressure exhaust port 5, and the user's hair is drawn into the inside of the device and straightened;

[0033] The drawn-in and straightened hair can be easily and clearly observed by the light sensor 10 to observe the hair roots, the light sensor 10 detects the hair, and since the light transmission rate / refractive index is different between gray hair and black hair, the light sensor 10 can effectively identify gray hair, and the dye nozzle is triggered to spray the gray hair evenly when the light sensor 10 detects the gray hair.

[0034] The above is only a better embodiment of the present utility model, and the utility model is not limited to the above-mentioned embodiments. As long as it achieves the technical effect of the utility model by the same means, any changes, equivalent replacements, improvements, etc. made within the spirit and principles of the present disclosure fall within the scope of the present utility model. All of these fall within the scope of the present utility model. There may be various modifications and changes to the technical solutions and / or their embodiments that fall within the scope of the present utility model.
