Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, in particular to a multi-dryer hair dryer. Background Art

[0002] Hair dryers are a common appliance in daily life, primarily used for drying hair. Some also offer hair care and styling functions. Existing hair dryers primarily consist of a heating wire and a small, high-speed fan. When powered, the heating wire generates heat, and the air from the fan passes through the wire and becomes hot air. If only the fan rotates without the heating wire heating, the air produced is cold air. The air from the hair dryer carries air molecules with increased kinetic energy, which collides with tiny water droplets on the hair, accelerating their evaporation and drying the hair. Because traditional hair dryers only have a single head, the air volume output is limited, and the direction of the air output is fixed and cannot be changed. Traditional hair dryers cannot adjust the airflow in multiple directions. Hairdrying and styling hair requires hairstylists to frequently adjust the direction and size of the head. This can cause wrist pain over time, resulting in a poor user experience. Therefore, improvements are needed. Summary of the Invention

[0003] Based on this, it is necessary to provide a multi-dryer hair dryer to address the above problems.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figures 1 to 5 As shown, a multi-air cylinder hair dryer includes a handle portion 1, a main air head 2 and a plurality of sub-air heads 3. The main air head 2 is connected to the upper end of the handle portion 1. A joint portion 4 is provided on the outside of the main air head 2. A notch groove 41 is provided on the outer peripheral surface of the joint portion 4. The output end of the rotary joint 5 passes through the notch groove 41 and is connected to the sub-air heads 3 in a one-to-one correspondence to drive the sub-air heads 3 to rotate. A driving member is also provided in the joint portion 4. The output end of the driving member is connected to the rotary joint 5 to drive the rotary joint 5 to deflect along the notch groove 41. The handle portion 1 is electrically connected to the main air head 2, the sub-air heads 3, the rotary joint 5 and the driving member. Specifically, the handle portion 1 serves as a grip, which is convenient for the user to grasp and perform the hair-drying operation. As can be understood, the handle portion 1 is hollow, facilitating the integration of electronic components such as the power supply unit and circuit control board within the handle portion 1. Furthermore, to facilitate user control of the main air blower 2 and the plurality of sub-air blowers 3, as well as wind speed adjustment, the handle portion 1 is provided with a plurality of buttons, which can be adjusted by the user through buttons, making it extremely convenient and quick to use. The main air blower 2 may be cylindrical, triangular, square, or other shapes, without specific limitation herein. A coupling 4 is provided on the outer shell of the main wind head 2, and the coupling 4 serves as the base of several sub-wind heads 3. In order to realize the design purpose of the sub-wind head 3 being able to rotate, we provide a rotating joint 5 corresponding to each sub-wind head 3 in the coupling 4, and use the rotating joint 5 to drive the sub-wind head 3 to rotate and adjust the air outlet direction of the sub-wind head 3. At the same time, in order to realize the rotation of the sub-wind head 3 around the main wind head 2, we install a driving member in the coupling 4, and the driving member is used to drive the sub-wind head 3 to revolve around the main wind head 2. Specifically, the driving member can be a motor, and a gear structure is added to its output end. Through the gear meshing structure, it is movably connected to the end of the rotating joint 5, and the sub-wind head 3 is driven to revolve by driving the rotating joint 5 to rotate. In order to prevent the revolution from deviation, we provide a notch groove 41 on the surface of the coupling 4 to limit the direction of the rotating joint 5 and prevent the sub-wind head 3 from deviating during revolution. During use, the user controls the rotation and revolution of the sub-head 3 through the handle 1, and adjusts the air outlet direction of the sub-head 3, so as to facilitate the air flow in multiple directions when drying and styling the user's hair, thereby maximizing the air volume for drying, keeping the shape and styling the hair.

[0022] Specifically, the handle portion 1 is in a rod shape, which is convenient for the user to grasp, and in order to obtain a better hand feel, a silicone sleeve can be provided on the outer surface of the handle portion 1.

[0023] Specifically, the output end of the rotary joint 5 is retractable. The retractable structure is a prior art and will not be elaborated here. When the output end of the rotary joint 5 is retracted, the extension length of the sub-head 3 can be adjusted, so that the sub-head 3 can rotate in three-dimensional space, or revolve around the main head 2, or move closer to or away from the main head 2, which greatly facilitates the styling of hair.

[0024] Specifically, there are two sub-heads 3, which are arranged on both sides of the main head 2. The two sub-heads 3 are mirror-symmetrically arranged. When the two sub-heads 3 revolve, they can revolve in a mirror-like manner, moving away from or approaching each other, so that the hair is symmetrical and more beautiful when styling.

[0025] like Figure 4 As shown, the main wind head 2 is further provided with a steel end head 6 on the side away from the handle portion 1, and the steel end head 6 is located between the two sub-wind heads 3. Since there are two sub-wind heads 3 on the left and right sides, the upper side of the main wind head 2 is heavy, and the steel end head 6 is provided for counterweight, which is convenient for flipping.

[0026] Specifically, the main air head 2 and the sub-air head 3 are both provided with an infrared sensor and a temperature sensor, and the infrared sensor and the temperature sensor are both electrically connected to the handle portion 1. Specifically, when sensing the wind speed, the infrared sensor's transmitter continuously emits infrared rays, which are partially absorbed and scattered when encountering flowing air molecules. The faster the wind speed, the stronger the absorption and scattering effect of the air molecules on the infrared rays, causing the infrared signal received by the infrared sensor's receiver to change. By detecting this signal change, the infrared sensor's receiver can infer the magnitude and direction of the wind speed. It is understandable that an electric heating wire is also integrated in the main air head 2 and the sub-air head 3, and the temperature sensor is used to sense the temperature of the hot air blown out. The handle portion 1 can then adjust the current in the electric heating wire to control the output hot air temperature.

[0027] Specifically, the output ends of the main air head 2 and the plurality of sub-air heads 3 are all provided with nozzles. The main air head 2 and the plurality of sub-air heads 3 equipped with nozzles will not disperse the output airflow, but will be better concentrated, which is convenient for styling hair.

[0028] like Figure 5As shown, the handle portion 1 has a built-in control panel 100, which includes a power module 101, a display module 102 and a main board 103. The main board 103 is electrically connected to the power module 101, the display module 102, the main air head 2, the plurality of sub-air heads 3, the rotary joint 5 and the driving member. The main board 103 serves as the main control panel. The user can control the start and stop of the main air head 2, the plurality of sub-air heads 3, the rotary joint 5 and the driving member through the switch buttons on the main control panel, and adjust the output wind force of the main air head 2, the plurality of sub-air heads 3, and the output air flow temperature. The display module 102 can be used to display the power level of the power module 101, the air flow speed blown out by the main air head 2 and the plurality of sub-air heads 3, etc., making it more intuitive for users to use.

[0029] A method for using a multi-dryer hair dryer comprises the following steps:

[0030] In step S1, the user activates the main air head 2 and several sub-air heads 3 via the handle 1. The output ends of the main air head 2 and several sub-air heads 3 output multiple streams of air in the same direction. Specifically, the user directly presses a button on the handle 1 to activate the main air head 2 and sub-air heads 3, which then blow air to dry and style the user's hair. To improve hair drying efficiency, the main air head 2 and sub-air heads 3 are integrated with electric heating wires, which blow out hot air streams. Multiple air streams are output simultaneously, greatly improving drying efficiency.

[0031] S2: The user controls the rotation and self-rotation of the plurality of sub-heads 3 around the main head 2 through the handle 1, thereby adjusting the direction of the airflow output by the sub-heads 3. Specifically, the sub-heads 3 are movably mounted on the periphery of the main head 2 via the joint 4 and connected to the joint via the rotary joint 5. The rotary joint 5 drives the sub-heads 3 to rotate, while the driving member built into the joint 4 drives the rotary joint 5 to revolve, allowing the sub-heads 3 to achieve self-rotation and revolve, bidirectionally adjusting the direction of the airflow blown out by the sub-heads 3, making it easier to style the user's hair using a single hair dryer, providing greater convenience and an excellent user experience.

[0032] S3, the user controls the start and stop of the electric heaters in the main air head 2 and the sub-air head 3 through the handle 1, and adjusts the temperature of the airflow output by the main air head 2 and the sub-air head 3. Specifically, the user can control the start and stop of the electric heating wires in the main air head 2 and the sub-air head 3, as well as the output power, through the buttons on the handle 1, and thus adjust the hot air temperature to prevent the temperature from being too high or too low, which may easily cause burns, and too low may reduce the drying efficiency of the hair.

[0033] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
