Description

Technical Field

[0001] This utility model relates to the field of hair care tools, and in particular to a hair comb with adjustable airflow direction. Background Technology

[0002] Hair straighteners are used to straighten hair. They mainly consist of a shell, comb teeth, and a main body (handle). Some also include heating devices, heat-conducting metal comb teeth (heated comb teeth), and heat insulation devices. Hair is straightened more easily after passing through the heated metal comb teeth. To improve the straightening effect, hair straighteners with blow-drying functions have been invented, and some even have the ability to change the direction of airflow. For example, Chinese Utility Model Patent Application 202520716132.8 disclosed by the applicant describes a hair care comb whose movable comb teeth can swing left and right as the hair is combed, closing one side of the airflow channel while opening the other side, so that the direction of airflow is basically the same as the direction of combing, thus achieving the effect of straightening the hair while drying it. Others have designed hair straighteners with manually adjustable airflow direction, such as the hair straightener and comb head disclosed in Chinese Utility Model Patent CN202223511644. By pressing a button, the air guide tube is driven to rotate to different positions, causing the airflow outlet to face different positions, thus adjusting the airflow direction. However, its adjustment structure is relatively complex and prone to failure, and the use of springs makes assembly more troublesome. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing an adjustable airflow comb with a simpler structure, more reasonable design, easier adjustment and assembly, and greater reliability and durability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an adjustable airflow direction comb, comprising a main body, a housing, comb teeth, comb bristles, an air duct, and an air duct conversion component. The comb teeth and comb bristles are disposed on the housing, and the air duct and air duct conversion component are disposed in the housing. The main body is connected to the housing, the air duct conversion component is connected to the main body, and the air duct is connected to the air duct conversion component. An air outlet is provided on the housing, and the air outlet is connected to the air duct. The air duct includes at least upper and lower parts. The upper air duct is separated by an air duct component disposed upward in the housing, and the lower air duct is separated by a windproof component disposed downward in the housing. A knob is provided outside the housing, and the knob is connected to a drive rod, which is connected to the air duct conversion component. An air outlet is provided on the air duct conversion component. By rotating the knob, the drive rod is driven to rotate the air duct conversion component so that the air outlet is aligned with the upper air duct, the lower air duct, or a portion of both the upper and lower air ducts simultaneously, thereby changing the airflow direction.

[0005] Furthermore, an end cap is provided at the front end of the housing, and a knob is provided on the outer end face of the end cap. The knob passes through the end cap and is connected to the drive rod. The drive rod passes longitudinally through the internal space of the housing and is connected to the air duct conversion component.

[0006] Furthermore, the air duct component has a structure that extends forward and upward at an angle, and the wind deflector has a structure that extends forward and downward at an angle. A baffle is provided at the end of the wind deflector that is opposite to the air duct conversion component. An air inlet is provided in the baffle. The shape and size of the air inlet are the same as the air inlet of the air duct component and the air outlet of the air duct conversion component. By rotating the air duct conversion component, the air outlet is aligned with the air inlet of the air duct component or the air inlet of the wind deflector to achieve an upward or downward airflow direction.

[0007] Furthermore, the comb teeth include fixed comb teeth and movable comb teeth, which are located in the upper region of the housing. An air outlet channel is provided in the fixed comb teeth, which is connected to the upper air duct. The movable comb teeth include movable comb teeth and movable comb tooth seats, which are movably installed at the air outlet channel of the fixed comb teeth to form a structure that can swing left and right. The movable comb teeth are connected to the upper air duct, and an airflow channel is formed by the gaps generated on its left and right sides when the movable comb teeth swing.

[0008] Furthermore, the fixed comb tooth component includes heated comb teeth and comb tooth sleeves. The heated comb teeth are connected to a heating element, and the comb tooth sleeves are connected to a comb tooth sleeve base. An air outlet channel is set in the comb tooth sleeve base. The comb tooth sleeves are fitted over the heated comb teeth, and each heated comb tooth corresponds to one comb tooth sleeve.

[0009] Furthermore, the two sides of the movable comb tooth seat extend outwards, forming a stop edge along the two sides of the air outlet channel on the comb tooth sleeve seat. By swinging the movable comb tooth to one side, the stop edge on the same side is pressed down to close the airflow channel on that side, and the airflow channel on the other side is exposed. The side edge of the movable comb tooth seat guides the air outlet to be consistent with the direction of hair combing.

[0010] Furthermore, the housing includes a sleeve and an inner frame. The sleeve is fitted over the outside of the inner frame, and the air duct components and wind baffle components are respectively assembled and fixed to the inner frame. A connector is fixed at the tail end of the inner frame, which is connected to the main body and allows the air duct conversion component to dock with the main body.

[0011] Furthermore, rotating shafts are provided at the front and rear ends of the movable comb tooth seat, and the rotating shafts are embedded in the comb tooth sleeves at both ends of the air outlet channel and covered by the inner frame to form a structure that can rotate left and right.

[0012] Furthermore, the heated comb teeth are arranged on both sides of the movable comb teeth, and the comb bristles are arranged on the sides and bottom of the housing.

[0013] Furthermore, four wind direction markings (up, down, left, and right) are provided on the outer end face of the end cap, and an arrow indicating the wind direction is provided on the knob.

[0014] Alternatively, a rotatable bushing can be connected to the drive rod, the bushing passing through the end cover and connecting to the knob, and the drive rod longitudinally passing through the internal space of the housing and connecting to the air duct conversion component; a sealing ring is provided on the air duct conversion component, and a partition is provided in the air outlet of the air duct conversion component, which divides the air outlet into two symmetrical halves.

[0015] This invention incorporates an air duct conversion component, controlled by a knob to rotate and switch the air intake position. Combined with the air duct component and the wind deflector, it alters the direction of airflow. Its simple and practical structure, easy assembly, low failure rate, and enhanced reliability and durability make it more durable. Simultaneously, the movable comb teeth swing left and right as the hair is combed, pressing down on one side to close its airflow channel while opening the other. Airflow flows outwards along the edge of the movable comb teeth, ensuring the direction of the blow-drying is essentially the same as the direction of hair combing. This means that when straightening hair, the airflow follows the direction of hair straightening, achieving a two-in-one function of blow-drying and straightening for superior straightening results.
