The term "and / or" as used herein includes any combination of one or more of the associated listed items.

[0025] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0026] like Figure 1As shown, this utility model proposes a hair dyeing device, including a housing 1, wherein the housing 1 is provided with an air inlet 2 and an air outlet 3, the air inlet 2 and the air outlet 3 are connected to form an air duct 4; the housing 1 is provided with a negative pressure exhaust port 5 between the air inlet 2 and the air outlet 3, the negative pressure exhaust port 5 is connected to the air duct 4 to form a negative pressure channel 6; a turbine 7 is provided at the air inlet 2; a hair dyeing component, the hair dyeing component includes a dye container 8 and a dye nozzle 9 connected to the dye container 8, the dye nozzle 9 is provided at the negative pressure exhaust port 5 of the housing 1; and a light sensor 10 is provided at the negative pressure exhaust port 5 of the housing 1. The hair is drawn in and straightened by a negative pressure exhaust vent 5. Then, a light sensor 10 detects the hair from the roots. When gray hair is detected, the hair dye nozzle is triggered to spray hair dye onto the gray hair. This allows users to accurately dye gray hair, effectively reducing the amount of hair dye used, avoiding excessive contact of hair dye with the scalp, reducing the chance of users being allergic to hair dye, saving hair dyeing costs, reducing environmental pollution, and maintaining a balance between hair health and appearance.

[0027] like Figures 1 to 2 As shown, in order to enable the light sensor 10 to detect hair more clearly and conveniently, a hair combing part 11 is provided extending outward from the negative pressure exhaust port 5 of the housing 1. The hair combing part 11 includes a plurality of comb teeth 12, and the light sensor 10 is disposed between two adjacent comb teeth 12. Therefore, by providing comb teeth 12, the hair can be combed neatly before detection, and at the same time, the comb teeth 12 can comb and separate the hair during detection so that it will not pile up in large quantities and affect the light sensor 10's detection of the hair.

[0028] like Figure 3 As shown, in order to ensure that the dye can be evenly sprayed onto the gray hair that needs to be dyed, the comb teeth 12 are provided with a hollow channel 13 for conveying the dye. The hollow channel 13 is connected to the dye container 8, and the dye nozzle 9 is disposed on the side wall of the comb teeth 12. When the light sensor 10 detects gray hair between two adjacent comb teeth 12, the dye is conveyed through the hollow channel 13 to the dye nozzle 9 disposed on the side wall of the comb teeth 12. The dye nozzle 9 evenly sprays the hair between two adjacent comb teeth 12, thereby avoiding uneven hair spraying.

[0029] like Figure 1As shown, in order to further assist the negative pressure exhaust port 5 in sucking in and straightening the hair, several rotating brush heads 14 are arranged parallel to each other between the negative pressure exhaust port 5 and the dye nozzle 9. The rotating brush heads 14 are provided with brush teeth 15 and brush bristles 16. Therefore, when the negative pressure exhaust port 5 generates a negative pressure exhaust airflow to suck in the hair, the parallel rotating brush heads 14 can cooperate with each other to further clamp and straighten the hair, thereby preventing the hair from falling out of the instrument and affecting the detection and hair dyeing effect.

[0030] like Figure 1 As shown, it also includes a handle 17, which is connected to the housing 1. The handle 17 has a control circuit board and a switch and power supply assembly electrically connected to the control circuit board inside.

[0031] like Figure 1 and Figure 2 As shown, in order to prevent the electrical components inside the handle 17 from overheating and burning out, the handle 17 is provided with heat dissipation holes 18, which are connected to the air duct 4 to form a heat dissipation channel 19; therefore, by providing heat dissipation holes 18 and heat dissipation channel 19, the airflow in the air duct 4 is rationally utilized, thereby achieving the function of heat dissipation.

[0032] like Figure 1 and Figure 2 As shown, to improve the accuracy of hair dyeing and reduce the amount of dye used, the dye container 8 is located on one side of the housing 1. The dye container 8 is equipped with a liquid supply pump 20, which is connected to the dye nozzles 9 individually via delivery pipes 21. Therefore, 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 the gray hair evenly, thereby achieving effective and targeted hair dyeing.

[0033] like Figure 1 and Figure 2 As shown, in order to suit users with long hair and facilitate cleaning and maintenance of the instrument, the housing 1 is cylindrical. The negative pressure exhaust port 5 and the air outlet 3 are positioned opposite each other at both ends of the housing 1. The air inlet 2 is positioned between the negative pressure exhaust port 5 and the air outlet 3 and is inclined towards the air outlet 3. Therefore, the hair of users with long hair can enter the instrument through the negative pressure exhaust port 5 and exit through the air outlet 3, thus accommodating users with long hair for normal use. At the same time, the straight channel between the oppositely positioned negative pressure exhaust port 5 and the air outlet 3 makes it easy to maintain and reduces the occurrence of corners and other hard-to-clean areas inside the instrument.

[0034] like Figure 1 and Figure 2 As shown, in order to prevent dust and other debris from entering the turbine 7 and affecting its normal operation, the housing 1 is provided with an air inlet filter 22 at the air inlet 2.

[0035] like Figure 1 As shown, in order to prevent the user's hair from being caught in the turbine 7, the housing 1 is provided with a protective net 23 at the air outlet of the turbine 7. Therefore, by providing the protective net 23, the turbine 7 is isolated, thereby preventing the user's hair from being caught in the turbine 7.

[0036] like Figure 4 The working principle shown is as follows: First, start the turbine 7 so that the outside air flows quickly from the air inlet 2 to the air outlet 3 and forms a fast airflow in the air duct 4. When the air duct 4 forms a fast airflow, the flow velocity at the negative pressure exhaust port 5 is small, and a negative pressure is formed at the negative pressure exhaust port 5 to suck the user's hair into the instrument and straighten it.

[0037] The straightened hair that is sucked in can be easily and clearly observed by the light sensor 10. The light sensor 10 detects the hair. Since the light transmittance / light refractive index is different between white hair and black hair, the light sensor 10 can effectively identify white hair. When the light sensor 10 detects white hair, it triggers the hair dyeing nozzle to spray the white hair evenly.

[0038] The above description is merely a preferred embodiment of this utility model. This utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effect, should be included within the scope of protection of this disclosure and fall under the protection scope of this utility model. Within the protection scope of this utility model, the technical solutions and / or implementation methods can have various modifications and variations.
