[0043] Example 1

[0044] A specific embodiment of this utility model is as follows: Figures 1 to 8 As shown, a hair care device is disclosed, comprising:

[0045] The working head 1 has an air outlet 12 for supplying air;

[0046] Handle 2, for the operator to hold;

[0047] The bending connection structure 3 is connected between the working head 1 and the handle part 2, and is configured to switch the working head 1 between a coaxial upright state and a bending state relative to the handle part 2.

[0048] In this embodiment, the working head 1 has a first air duct, one end of which is the air outlet 12 of the working head 1. The handle part 2 has a second air duct, and the bending connection structure 3 has a third air duct, which connects the first air duct and the second air duct. Since the second air duct is stretchable and its length is adjustable, the three air ducts are connected to form the entire stretchable air duct of the hair care device.

[0049] In this embodiment, the working head 1 has a head shell 11, and the handle part 2 has a handle shell 21. The head shell 11 and the handle shell 21 form an installation space at their coaxial connection point. The bending connection structure 3 includes a flexible pipe 31, which is disposed within the installation space. The first end of the flexible pipe 31 is fixedly connected to the head shell 11, and the second end of the flexible pipe 31 is fixedly connected to the handle shell 21. When the working head 1 and the handle part 2 are in a coaxial upright state, the flexible pipe 31 is hidden within the installation space. When the working head 1 and the handle part 2 are in a bent state, the connection point between the head shell 11 and the handle shell 21 separates, and the flexible pipe 31 is stretched and bent, achieving the bending of the air duct and becoming exposed.

[0050] Specifically, the first end of the flexible tube 31 is fixedly connected to the head shell 11 via the first fixing member 32, and the second end of the flexible tube 31 is fixedly connected to the handle shell 21 via the second fixing member 33.

[0051] For example, the flexible duct 31 has an inner tube 311 and may also have an outer tube 312. Both the inner tube 311 and the outer tube 312 are flexible and stretchable. Optionally, the inner tube 311 is a spring tube. If an outer tube 312 is provided, it is sleeved outside the inner tube 311 and serves as an elastic decorative element, providing both decoration and protection. Optionally, the two ends of the inner tube 311 and the outer tube 312 are fixed to the first fixing member 32 and the second fixing member 33 respectively by applying glue or in-mold injection molding. When bent at a specified angle, the spring tube and the outer elastic decorative tube are in a stretched state, realizing the bending of the air duct.

[0052] In this embodiment, the bending connection structure 3 further includes a locking mechanism 34, which is configured to control the rotation angle and positioning of the working head 1 relative to the handle part 2.

[0053] In one alternative embodiment, the bending connection structure 3 adopts an invisible hinge rotation positioning scheme. Specifically, the locking mechanism 34 includes a hinged first part 341 and a second part 342. The first end of the first part 341 is fixedly connected to the head shell 11, and the first end of the second part 342 is fixedly connected to the handle shell 21. The second end of the first part 341 is rotatably connected to the second end of the second part 342 through a pivot 343.

[0054] The locking mechanism 34 further includes a first bracket 13 and a second bracket 344. The first bracket 13 is disposed on the outer wall of the head housing 11, and the second bracket 344 is disposed on the outer wall of the handle housing 21. The first end of the first part 341 is fixedly connected to the first bracket 13, and the first end of the second part 342 is fixedly connected to the second bracket 344. For example, the first part 341 is fixedly connected to the first bracket 13 of the head housing 11 by in-mold injection molding, and the second part 342 is fixedly connected to the second bracket 344 on the handle housing 21. The first part 341 and the second part 342 are connected to each other by a pivot 343. When the working head 1 and the handle part 2 are in a coaxial upright state, the outer surface of the first part 341 and the outer surface of the second part 342 are substantially coplanar, making the exposed part of the locking mechanism 34 appear flat.

[0055] Furthermore, a locking part 3411 is provided on the side end face of the first part 341, and a locking engagement part 3441 is provided on the second bracket 344. The locking part 3411 and the locking engagement part 3441 fix the first part 341 and the second part 342 after they are rotated by a predetermined angle. That is to say, the locking part 3411 and the locking engagement part 3441 keep the working head 1 and the handle part 2 in a coaxial upright state or a bent state, so as to maintain a straight or bent working state.

[0056] In one alternative embodiment, one of the locking part 3411 and the locking engagement part 3441 is a spring positioning bead, and the other is a groove. The spring positioning bead and the groove are arranged in a group, and the spring positioning bead locks the first part 341 and the second bracket 344 by engaging with the groove. The locking mechanism 34 may have one set of spring positioning beads and grooves, or it may have two sets of spring positioning beads and grooves, which are arranged symmetrically.

[0057] The adjustable angle can be determined by adjusting the number and arrangement of grooves and spring positioning beads in each group.

[0058] In one alternative embodiment, each group contains three grooves located at the three vertices of an equilateral triangle; each group also contains two spring positioning beads, with the distance between the two spring positioning beads equal to the distance between any two adjacent spring positioning beads. This arrangement of three grooves and two spring positioning beads per group allows for both 180° linear and 90° vertical angle adjustments. Specifically, when the working head 1 is coaxially upright relative to the handle 2, one side of the equilateral triangle containing two grooves in each group is parallel to the axis of the working head 1 or handle 2; the center line of the triangle passing through the third groove in each group is perpendicular to the axis of the working head 1 or handle 2. Figure 8 As shown, three grooves are provided on each of the two side walls of the first part 341, namely the first groove 3411a, the second groove 3411b, and the third groove 3411c. The three grooves cooperate with the two positioning beads on the second bracket 344. When the working head 1 and the handle part 2 are in a coaxial upright state, the outer surfaces of the first part 341 and the second part 342 of the bending connection structure 3 are flat, and the two spring positioning beads in the same group are respectively in the first groove 3411a and the second groove 3411b in the initial position. When the working head 1 and the handle part 2 are in a bent state, the bending causes the head shell 11 of the working head 1 to rotate around the pivot 343 by a specified angle. At this time, the two spring positioning beads in the same group are in the second groove 3411b and the third groove 3411c.

[0059] In another optional embodiment, each group contains multiple grooves, which are evenly distributed on a segment of an arc; each group contains one spring positioning bead. When the working head 1 and the handle 2 rotate, the spring positioning bead engages with grooves at different positions on the arc to adjust the bending angle. The segment of the arc can be a quarter circle. In the initial state, i.e., in a coaxial upright position, the spring positioning bead engages with the groove at one end of the arc; when the working head 1 and the handle 2 are bent to a maximum angle of 90°, the spring positioning bead engages with the groove at the other end of the arc.

[0060] Considering that there will be a certain gap at the joint between the handle housing 21 and the head housing 11 when the working head 1 and the handle 2 are in a coaxial upright state, a magnetic auxiliary positioning is used to eliminate or reduce the gap at the joint. Specifically, the locking mechanism 34 also includes a magnetic auxiliary positioning member 345, which is disposed on the outer wall of the handle housing 21 on the opposite side of the second bracket 344. The magnetic auxiliary positioning member 345 can extend towards the outer wall of the head housing 11 and can magnetically attract the end of the outer wall of the head housing 11. That is, when the working head 1 and the handle 2 are in a coaxial upright state, the magnetic auxiliary positioning member 345 and the second bracket 344 are located on opposite sides of the axis of the handle head.

[0061] In this embodiment, a sleeve 14 is provided inside the head shell 11, and a heating wire 15 is provided on the sleeve 14. The heating wire 15 can heat the air passing through the first air duct.

[0062] In this embodiment, the handle housing 21 houses a motor 22, a fan blade assembly, and a PCB board 23. The motor 22 is fixedly mounted inside the handle housing 21 by a motor mounting bracket, and drives the fan blade assembly to rotate, thereby achieving airflow. The handle housing 21 also has an air inlet 24, which communicates with a second air duct and is equipped with a filter. The PCB board 23 is located inside the handle housing 21 closer to the air inlet 24 than the motor 22 and the fan blade assembly.

[0063] It should be noted that the handle housing 21 and the head housing 11 can be cylindrical or other cylindrical structures.

[0064] The main body of the hair care appliance consists of a working head 1 and a handle 2, which can be bent to achieve multi-angle use. When using it to blow-dry hair, the working head 1 can be bent to a 90-degree angle with the handle or other suitable angles. When using it to curl hair, the working head 1 can be straightened, coaxially with the handle 2, for easy curling. Of course, users can choose a comfortable angle to blow-dry hair upright or curl hair in a bent position, thus satisfying different user habits and allowing users to choose a comfortable angle to use the machine.

[0065] Compared with the prior art, the hair care device provided in this embodiment has the following beneficial effects:

[0066] 1. The working head and handle are connected by a flexible tube. The flexible tube is stretchable, which allows the hair care device to be used upright or bent, with minimal airflow loss. When the user wants to bend the hair care device, they only need to bend the working head, and the flexible tube will rotate and stretch around the pivot, thereby bending the airflow. It can be folded at multiple angles to meet the user's needs for multi-angle use.

[0067] 2. The hair care device of this application has a simple structure and a soft shape. The locking mechanism adopts a rotating hinge and positioning structure, which can be directly bent without the need for manual unlocking of the lock, making it simple and reliable.
