Description

Technical Field

[0001] The invention relates to the technical field of household appliances, in particular to a hair dryer with multiple air cylinders. Background Art

[0002] As a common electrical appliance in daily life, hair dryers are mainly used to dry hair. At the same time, some hair dryers also have functions such as hair care and styling. Existing hair dryers are mainly composed of a group of electric heating wires and a small high-speed fan. When powered on, the electric heating wires will generate heat, and the wind blown out by the fan will become hot air after passing through the electric heating wires. If only the fan rotates but the electric heating wire is not hot, cold air will be blown out. The wind blown out by the hair dryer carries air molecules with increased kinetic energy, which accelerates their evaporation by colliding with tiny water droplets on the hair, thereby drying the hair. Since traditional hair dryers have only one wind head, the wind volume output by the wind head is limited, and the wind direction output by the wind head is fixed and cannot be changed. Traditional hair dryers cannot achieve multiple wind direction adjustments. When drying and styling hair, hairstylists need to adjust the wind direction and size of the wind head frequently. After using it for a long time, the wrist will be very sore, and the user experience is not good, so it needs to be improved. Summary of the invention

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

[0004] A multi-air cylinder hair dryer comprises a handle portion, a main air head and a plurality of sub-air heads, wherein the main air head is connected to the upper end of the handle portion, a coupling portion is arranged on the outer side of the main air head, a notch groove is arranged on the outer peripheral surface of the coupling portion, an output end of a rotary joint passes through the notch groove and is connected to the sub-air heads one by one to drive the sub-air heads to rotate, a driving member is also arranged in the coupling portion, the output end of the driving member is connected to the rotary joint to drive the rotary joint to deflect along the notch groove, and the handle portion is electrically connected to the main air head, the sub-air heads, the rotary joint and the driving member.

[0005] Preferably, the handle portion is in a rod shape.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] like Figures 1 to 5As 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, wherein the main air head 2 is connected to the upper end of the handle portion 1, a coupling portion 4 is provided on the outer side of the main air head 2, a notch groove 41 is provided on the outer peripheral surface of the coupling portion 4, an output end of a rotary joint 5 passes through the notch groove 41, and is connected to the sub-air heads 3 one by one to drive the sub-air heads 3 to rotate, a driving member is also provided in the coupling portion 4, and 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, and 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 is used as a grip, which is convenient for the user to grasp and perform the hair-drying operation. It is understandable that the handle 1 is hollow, which is convenient for integrating electronic components such as the power supply unit and the circuit control board into the handle 1. At the same time, in order to facilitate the user to control the main wind head 2 and the start and stop of several sub-wind heads 3, as well as adjust the wind force, several buttons are integrated on the handle 1, and the user can control them through the buttons, which is extremely convenient and quick to use. The main wind head 2 can be cylindrical, triangular, square or other shapes, which are not specifically limited here. A coupling part 4 is provided on the outer sleeve of the main wind head 2, and the coupling part 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 part 4, and utilize 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 part 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 installed at its output end, which is movably connected to the end of the rotating joint 5 through a gear meshing structure, 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 part 4 to limit the direction of the rotating joint 5 and prevent the sub-wind head 3 from deviating during revolution. When in 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 airflow in multiple directions when blow-drying and styling the user's hair, thereby maximizing the air volume for drying, keeping the shape and styling the hair.

[0026] 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 handle portion 1.

[0027] Specifically, the output end of the rotary joint 5 is retractable, and 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-air head 3 can be adjusted, so that the sub-air head 3 can rotate in three-dimensional space, or revolve around the main air head 2, or move closer to or away from the main air head 2, which greatly facilitates the use of hair styling.

[0028] 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-symmetrical manner, moving away from or approaching each other, so that the hair is symmetrical and more beautiful when styling.

[0029] 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 two sub-wind heads 3 are arranged on the left and right sides, the upper side of the main wind head 2 is heavy, and a steel end head 6 is provided for counterweight, which is convenient for flipping.

[0030] Specifically, the main wind head 2 and the sub-wind 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 transmitter of the infrared sensor continuously emits infrared rays, and these infrared rays will be partially absorbed and scattered when encountering flowing air molecules. The faster the wind speed, the stronger the absorption and scattering effect of air molecules on infrared rays, causing the infrared signal received by the receiver of the infrared sensor to change. By detecting this signal change, the receiver of the infrared sensor can infer the size and direction of the wind speed. It is understandable that an electric heating wire is also integrated in the main wind head 2 and the sub-wind head 3, and the temperature sensor is used to sense the temperature of the hot air blown out of the airflow, and then the handle portion 1 can adjust the current in the electric heating wire, thereby controlling the output hot air temperature.

[0031] Specifically, the output ends of the main air head 2 and the plurality of sub-air heads 3 are all provided with nozzles. The output airflows of the main air head 2 and the plurality of sub-air heads 3 equipped with nozzles will not be dispersed but better concentrated, which is convenient for styling hair.

[0032] like Figure 5 As shown, the handle part 1 has a built-in control panel 100, and the control panel 100 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 wind head 2, the plurality of sub-wind 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 wind head 2, the plurality of sub-wind heads 3, the rotary joint 5 and the driving member through the switch button on the main control panel, and adjust the output wind force of the main wind head 2, the plurality of sub-wind heads 3, and the output airflow temperature. The display module 102 can be used to display the power of the power module 101, and the airflow speed blown out by the main wind head 2 and the plurality of sub-wind heads 3, etc., which is more intuitive for users to use.

[0033] A method for using a multi-dryer hair dryer comprises the following steps:

[0034] S1, the user starts the main air head 2 and several sub-air heads 3 through the handle 1, and the output ends of the main air head 2 and several sub-air heads 3 output several streams of airflow in the same direction. Specifically, the user directly presses the button on the handle 1 to control the main air head 2 and the sub-air heads 3 to start, blow, and dry and style the user's hair. In order to improve the drying efficiency of the hair, the main air head 2 and the sub-air heads 3 are integrated with electric heating wires to blow out hot air flow, and multiple air flows are blown out at the same time, which greatly improves the drying efficiency.

[0035] S2, the user controls the rotation and self-spin of the plurality of sub-heads 3 around the main head 2 through the handle 1, and adjusts 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 through the joint 4, and are connected to the joint through the rotary joint 5. The rotary joint 5 drives the sub-heads 3 to rotate, and the driving member built into the joint 4 drives the rotary joint 5 to revolve, so that the sub-heads 3 can realize self-spin and revolve, and the wind direction of the airflow blown out by the sub-heads 3 can be adjusted in both directions, making it easier to use a hair dryer to style the user's hair, which is more convenient to use and provides an excellent experience.

[0036] S3, the user controls the start and stop of the electric heating 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 wire in the main air head 2 and the sub-air head 3, as well as the output power, through the button on the handle 1, and then adjust the hot air temperature to prevent the temperature from being too high or too low, which may easily cause burns, and which may reduce the drying efficiency of the hair.

[0037] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
