Description

Technical Field

[0001] This utility model relates to a hair dryer styling tool, belonging to the field of hair dryer technology. Background Technology

[0002] As people's consumption levels rise, their demands for various daily necessities are also increasing. For example, hair dryer users are no longer limited to just drying their hair; more and more users hope to achieve styling effects such as curling or straightening their hair using hair dryers.

[0003] To meet user needs, existing hair dryers have a hinge at the connection between the nozzle head and the handle, allowing for a foldable design. In the folded state, rotating the nozzle head outwards by 90° makes it perpendicular to the handle, switching to dryer mode. In dryer mode, rotating the nozzle head outwards by another 90° makes it parallel to the handle, switching to styling mode. By installing or changing styling nozzles, such as air curlers or oval combs, users can curl or straighten their hair, thus meeting their hair dryer usage needs.

[0004] However, in the hair styling mode, the head and handle of existing hair dryers are not on the same axis. When the user holds the handle, the air outlet is on the other side of the handle's rotation axis. This causes the axis of the user's hand rotation to be inconsistent with the air outlet. Users need to frequently rotate their hands to adjust the air outlet angle, making the process of adjusting the blowing angle cumbersome and resulting in a poor user experience. Summary of the Invention

[0005] This utility model addresses the aforementioned deficiencies of the prior art by providing a blower styling tool.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hair dryer includes a hair dryer and a handle. The hair dryer and the handle are connected by a dual-axis rotating mechanism. The dual-axis rotating mechanism includes a rotating shaft A, a rotating shaft B and a connecting shaft. The rotating shaft A is installed at the end of the handle, the rotating shaft B is installed at the end of the hair dryer, one end of the connecting shaft is rotatably installed on the rotating shaft B, and the other end of the connecting shaft is rotatably installed on the rotating shaft A.

[0007] The beneficial effects of this utility model are as follows: This utility model innovatively adopts a dual-axis design. Due to the presence of two axes, axis A and axis B, the hair dryer has three modes: storage mode (folded state), blow-drying mode (the nozzle and handle are perpendicular), and hair styling mode (the nozzle and handle are parallel). In hair styling mode, the nozzle and handle of this utility model are parallel and coincident, making it smoother and more convenient for users to adjust the air outlet angle of the hair dryer, thus improving the user experience.

[0008] Furthermore, the end of the air duct is provided with an air inlet shell, which is fitted onto the air duct and has an air inlet grille.

[0009] The beneficial effect of adopting the above-mentioned further technical solution is that the air inlet shell is located at the end of the air duct, which makes full use of the space and makes the structure of this utility model more compact.

[0010] Furthermore, the outer contour of the end of the air inlet housing is hemispherical, and the center of the outer contour of the end of the air inlet housing coincides with the axis of the rotating shaft B.

[0011] The beneficial effect of adopting the above-mentioned further technical solution is that the outer contour of the end of the air inlet shell is hemispherical, which makes the air inlet grille change from a flat surface to a three-dimensional surface, and can make full use of the air inlet area.

[0012] Furthermore, the air inlet housing is provided with a clearance notch to avoid the connecting shaft.

[0013] The beneficial effect of adopting the above-mentioned further technical solutions is that it effectively avoids interference between the air inlet shell and the connecting shaft during the rotation of the air duct.

[0014] Furthermore, the dual-axis rotation mechanism also includes a first connecting half-shell and a second connecting half-shell, which engage with each other to form a cylindrical connecting shell, and the connecting shell is inserted into the end of the air duct.

[0015] The beneficial effects of adopting the above-mentioned further technical solution are: by connecting half shell one and connecting half shell two to form a connecting shell, the connecting shell is inserted into the end of the air duct, thereby facilitating the installation of the rotating shaft B and the air inlet shell on the air duct, realizing the connection between the air duct and the handle and the air inlet shell, improving the space utilization rate, and making the structure more compact.

[0016] Furthermore, the ends of the first connecting half-shell and the second connecting half-shell are respectively provided with mounting slots, and the mounting slots are provided with mounting holes, and the two ends of the rotating shaft B are respectively inserted into the mounting holes.

[0017] The beneficial effect of adopting the above-mentioned further technical solution is that by connecting half shell one and connecting half shell two through the mounting slots, an installation space for accommodating the rotating shaft B and a space for the connecting shaft to rotate are formed.

[0018] Furthermore, the handle has a hemispherical outer contour at one end of the rotating shaft A, and the center of the hemispherical outer contour of the handle coincides with the axis of the rotating shaft A.

[0019] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: the outer contour of the end of the air inlet shell is hemispherical, and its center coincides with the axis of the rotating shaft B. The outer contour of the end of the handle is also hemispherical, and its center coincides with the axis of the rotating shaft A. Since the distance from each point on the sphere to the center of the sphere is equal, the distance between the end of the air inlet shell and the end of the handle is always equal or close during the rotation of the air duct around the rotating shaft B or around the rotating shaft A. This makes the exposed area of ​​the connecting shaft between the end of the air inlet shell and the end of the handle the smallest when viewed from the side in all three modes of the blower styling device. This makes the volume of the blower styling device of this utility model compact in all three modes, achieving a small and practical effect.

[0020] Furthermore, the handle is provided with a clearance groove for the connecting shaft to rotate.

[0021] Furthermore, a motor is installed inside the air duct, and the motor is located inside the connecting shell formed by the first connecting half shell and the second connecting half shell.

[0022] The beneficial effect of adopting the above-mentioned further technical solution is that the motor is set at the front end of the dual-axis rotation mechanism, making full use of the space of the blower and making the structure compact. Attached Figure Description

Detailed Implementation

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] See Figures 1-4 A hair dryer includes a blower head 100 and a handle 200. The blower head 100 and the handle 200 are connected by a dual-axis rotation mechanism. The dual-axis rotation mechanism includes a rotating shaft A210, a rotating shaft B140, and a connecting shaft 300. The rotating shaft A210 is installed at the end of the handle 200, the rotating shaft B140 is installed at the end of the blower head 100, and one end of the connecting shaft 300 is rotatably mounted on the rotating shaft B140. Specifically, the dual-axis rotation mechanism also includes a connecting half-shell 120 and a connecting half-shell 130. 120 and connecting half-shell 130 engage to form a cylindrical connecting shell, which is inserted into the end of the air duct 100. Each end of connecting half-shell 120 and connecting half-shell 130 has a mounting groove 150, and each mounting groove 150 has a mounting hole 160. Both ends of the rotating shaft B140 are inserted into the mounting holes 160. The mounting grooves 150 of connecting half-shell 120 and connecting half-shell 130 engage to form a mounting space for accommodating the rotating shaft B140 and a space for the connecting shaft 300 to rotate. The other end of the connecting shaft 300 is rotatably mounted on the rotating shaft A210.

[0030] The end of the air duct 100 is provided with an air inlet shell 110, which is snapped onto the air duct 100. The air inlet shell 110 is provided with an air inlet grille. The air inlet shell 110 is provided with a clearance notch 170 to avoid the connecting shaft 300.

[0031] The outer contour of the end of the air inlet housing 110 is hemispherical, and the center of the sphere of the outer contour of the end of the air inlet housing 110 coincides with the axis of the rotating shaft B140. The outer contour of the end of the handle 200 with the rotating shaft A210 is hemispherical, and the center of the sphere of the outer contour of the end of the handle 200 coincides with the axis of the rotating shaft A210.

[0032] The hair dryer of this invention innovatively adopts a dual-axis design, giving the hair dryer 100 two rotating central axes: axis A210 and axis B140. This allows the hair dryer to have three modes: storage mode (folded state), blow-drying mode (hair dryer 100 is perpendicular to handle 200), and hair styling mode (hair dryer 100 is parallel to handle 200).

[0033] In storage mode, the central axis M of the air blower 100 is parallel to the central axis P of the handle 200 (e.g., Figure 2By rotating the blower 100 90° clockwise around the pivot A210, it unfolds. At this time, the central axis M of the blower 100 is perpendicular to the central axis P of the handle 200 at a 90° angle, thus switching to the blowing mode (e.g., Figure 3 When the hairdryer 100 is in blow-drying mode, it rotates 90° clockwise around the pivot B140. At this time, the central axis M of the hairdryer 100 is parallel to and coincides with the central axis P of the handle 200, thus switching to hair styling mode (e.g., ...). Figure 4 This utility model, through its dual-axis design, enables the hair dryer to function in hair styling mode (such as...). Figure 4 Because the central axis M of the hair dryer 100 is parallel and coincident with the central axis P of the handle 200, the user can adjust the airflow angle of the hair dryer more smoothly and conveniently when using it with hair styling nozzles, resulting in a better user experience.

[0034] This invention designs the outer contour of the air inlet shell 110 as a hemisphere, with its center coinciding with the axis of the rotating shaft B140. Similarly, the outer contour of the handle 200 is also hemisphere-shaped, with its center coinciding with the axis of the rotating shaft A210. Since the distance from each point on the sphere to the center is equal, the distance between the air inlet shell 110 and the handle 200 remains equal or nearly equal during the rotation of the air duct 100 around the rotating shaft A210 or B140. This minimizes the exposed area of ​​the connecting shaft 300 between the air duct 100 and the handle 200 when viewed from the side in all three modes, achieving a compact and practical effect.

[0035] The handle 200 is provided with a clearance groove for the connecting shaft 300 to rotate.

[0036] The ventilation duct 100 is equipped with a motor 500, which is located in the connecting shell formed by connecting half shell 120 and connecting half shell 2 130.

[0037] The hair dryer of this invention also includes a circuit control system, which includes a rectifier module, a voltage conversion module, an IPM (Intelligent Power Module), an MCU (Microcontroller Unit), a current detection unit, a wind temperature detection unit, and a heating unit. The circuit control system ensures the stability of the hair dryer during operation, improves the user experience, and extends its service life.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
