Abstract
Description
Technical Field
[0001] This utility model relates to the field of hair dryer technology, and in particular to a foldable hair dryer. Background Technology
[0002] Existing folding hair dryers are too complicated to assemble, making them difficult to maintain. They have too many parts, resulting in high costs, and are prone to jamming. Utility Model Content
[0003] In view of the above situation, it is necessary to provide a foldable hair dryer that solves at least one of the above problems.
[0004] A foldable hair dryer includes a hair dryer and a handle. A rotating structure is provided at the connection between the hair dryer and the handle. The rotating structure includes a locking structure and a rotation limiting structure arranged sequentially from top to bottom.
[0005] The handle is configured as a symmetrical two-part assembly, and the end of the handle connected to the hair dryer is configured as an inclined first slope. Opposite semi-circular through holes are provided on the first slope of the assembly.
[0006] The end of the hair dryer connected to the handle is configured as a second inclined surface corresponding to the first inclined surface, and the rotating structure is disposed on the second inclined surface;
[0007] The two semi-circular through holes are respectively engaged with the two sides of the locking structure, and the handle is provided with a limiting member that cooperates with the rotation limiting structure. The rotation limiting structure extends into the handle and cooperates with the limiting member, so that the hair dryer can rotate relative to the handle by a preset angle.
[0008] When the blower is folded, its axis is parallel to the handle axis.
[0009] By incorporating a rotating structure at the connection between the hair dryer and the handle, the hair dryer and handle can rotate relative to each other, allowing for folding and storage. Furthermore, since only one rotating structure is used, and the connection between the handle, hair dryer, and rotating structure is very simple—simply dividing the handle into two parts and engaging with the locking mechanism in the rotating structure—the assembly of the hair dryer, handle, and rotating structure can be completed. The assembly process is not overly complicated, making maintenance easy. With fewer parts, the cost is lower, and there is no risk of jamming. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0026] Please see Figure 1-10A foldable hair dryer according to an embodiment of the present utility model includes a hair dryer 100 and a handle 200. A rotating structure 400 is provided at the connection between the hair dryer 100 and the handle 200. The rotating structure 400 includes a locking structure 430 and a rotation limiting structure 410 arranged sequentially from top to bottom.
[0027] The handle 200 is configured as a symmetrical two-part assembly 210. The end of the handle 200 connected to the blower 100 is configured as an inclined first slope 250. Opposite semi-circular through holes 220 are provided on the first slope 250 of the assembly 210.
[0028] The end of the hair dryer 100 connected to the handle 200 is configured as a second inclined surface corresponding to the first inclined surface 250, and the rotating structure 400 is disposed on the second inclined surface;
[0029] The two semi-circular through holes 220 are respectively engaged with the two sides of the locking structure 430, and the handle 200 is provided with a limiting member 300 that cooperates with the rotation limiting structure 410. The rotation limiting structure 410 extends into the handle 200 and cooperates with the limiting member 300, so that the hair dryer 100 can rotate relative to the handle 200 by a preset angle.
[0030] In the folded state, the axis of the hair dryer 100 is parallel to the axis of the handle 200.
[0031] In this embodiment, a rotating structure 400 is provided at the connection between the hair dryer 100 and the handle 200, allowing the hair dryer 100 and the handle 200 to rotate relative to each other, thereby folding them up for storage. Moreover, since only one rotating structure 400 is used, and the connection method between the handle 200, the hair dryer 100 and the rotating structure 400 is very simple, simply dividing the handle 200 into two parts and cooperating with the locking structure 430 in the rotating structure 400, the assembly of the hair dryer 100, the handle 200 and the rotating structure 400 can be completed. The assembly is not too complicated, it is easy to maintain, there are few parts, the cost is low, and there is no jamming.
[0032] The rotating structure 400 includes a locking structure 430 and a rotation limiting structure 410. The locking structure 430 is designed to work with the handle 200 to connect the handle 200 and the hair dryer 100, while also allowing them to rotate relative to each other. The rotation limiting structure 410 is designed to fix the relative positions of the hair dryer 100 and the handle 200 at multiple preset angles. For example, in the use state or the folded state, the axes of the hair dryer 100 and the handle 200 are perpendicular in the use state, while in the folded state, the axes of the hair dryer 100 and the handle 200 are parallel.
[0033] The handle 200 is designed as a symmetrical two-part assembly 210, which engages with the locking structure 430 during assembly, allowing the handle 200 and the hair dryer 100 to be rotatably connected. The connection between the handle 200 and the hair dryer 100 is an inclined surface, and the handle 200 is provided with a circular through hole (two sets of semi-circular through holes 220 combined together). The second inclined surface of the hair dryer 100 also has a circular through hole, which can facilitate the connection of the handle 200 and the electronic components in the hair dryer 100 by pulling the wire.
[0034] The handle 200 is equipped with a limiting component 300 in conjunction with a rotation limiting structure 410, so that when the hair dryer 100 and the handle 200 rotate relative to each other to a preset angle, they can be relatively stable and will not easily deviate from that angle.
[0035] When the hair dryer 100 and the handle 200 rotate relative to each other, they rotate with the first inclined plane 250 or the second inclined plane as the plane of rotation and the central axis of the rotating structure 400 as the axis of rotation.
[0036] During installation, align the semi-circular through hole 220 on the two-part assembly 210 with the locking structure 430, and then merge the two-part assembly 210 and lock it onto the locking structure 430. The inner wall of the circular through hole formed just abuts against the outer wall of the locking structure 430. At this time, the limiting member 300 is engaged with the rotation limiting structure 410, which limits and positions the rotation angle of the rotation limiting structure 410.
[0037] The two halves of the assembly 210 can be finally secured together by a detachable snap-fit connection and / or screw connection.
[0038] Preferably, the preset angles are 0° and 180°, which are the relative rotation angles of the hair dryer 100 and the handle 200 in the use state and the folded state.
[0039] In one embodiment, at least one set of limiting protrusions 240 are provided on the second inclined surface and / or the first inclined surface 250.
[0040] In this embodiment, by setting the limiting protrusion 240, the first inclined surface 250 and the second inclined surface will not be in close contact after the handle 200 and the hair dryer 100 are installed, thereby reducing the coefficient of friction and avoiding excessive tightness during relative rotation.
[0041] In one embodiment, the limiting protrusion 240 is an arc-shaped protrusion.
[0042] In this embodiment, the coefficient of friction is further reduced.
[0043] In one embodiment, the limiting protrusion 240 is a set of protrusions surrounding the outer side of the semi-circular through hole 220 of the assembly 210.
[0044] In this embodiment, the contact area is larger, which adjusts the balance between the coefficient of friction and the comfort of use, and the force is applied more evenly, so that the blower 100 and the handle 200 will not swing when rotating.
[0045] In one embodiment, the rotation limiting structure 410 includes a cylindrical rotating member disposed in the middle of the second inclined surface. The rotating member has a hollowed-out middle section and at least one set of symmetrical limiting grooves 411 formed on its inner sidewall. The outer sidewall of the limiting member 300 is provided with limiting protrusions 320 corresponding to the limiting grooves 411. The limiting member 300 is disposed in the rotating member, and the circles of the limiting member 300 and the rotating member coincide.
[0046] In this embodiment, the cylindrical rotating member can extend into the circular through hole formed by the assembly 210, and the limiting member 300 is fitted into the cylindrical rotating member in the handle 200, so that the limiting protrusion 320 and the limiting groove 411 are engaged accordingly. In the use state and the folded state, the limiting protrusion 320 is located in the limiting groove 411, so as to maintain stability in both states.
[0047] In one embodiment, a limiting ring is provided on the inner wall of the rotating component on the side of the limiting groove 411 near the blower 100.
[0048] In this embodiment, by setting a limiting ring, the relative position of the rotating component and the limiting component 300 in the direction of the rotation axis can be restricted, preventing the rotating component from moving too far downward and causing the limiting protrusion 320 on the limiting component 300 to disengage from the limiting groove 411. At the same time, it can prevent the first inclined surface 250 and the second inclined surface from making excessive contact and reduce the coefficient of friction.
[0049] In one embodiment, the rotating member extends outward from the outer periphery of the blower 100 to form a retaining ring 420. There is an installation gap between the retaining ring 420 and the second inclined surface. The installation gap forms the locking structure 430 so that the two semi-circular through holes 220 can be engaged respectively.
[0050] In this embodiment, by setting a retaining ring 420, there is an installation gap between the retaining ring 420 and the second inclined surface. The installation gap forms the locking structure 430 so that the two halves of the semi-circular through holes 220 can be engaged respectively. This structure is simple to install and allows the handle 200 and the blower 100 to rotate relative to each other.
[0051] In one embodiment, a limiting block 412 is provided on the side of the retaining ring 420 away from the hair dryer 100. Two limiting blocks 412 are provided, and the two limiting blocks 412 are respectively provided on both sides of the rotating member. The handle 200 is provided with a limiting stop corresponding to the limiting block 412. When the hair dryer is in use and folded, the two limiting blocks 412 respectively abut against the corresponding limiting stop.
[0052] In this embodiment, by setting the limiting block 412, excessive rotation can be avoided in the use state or folded state, which would cause the limiting protrusion 320 to disengage from the limiting groove 411, thereby preventing the wire from being twisted excessively and damaged.
[0053] In one embodiment, the limiting groove 411 has arc-shaped protrusions on both sides.
[0054] In this embodiment, the arc-shaped protrusion facilitates the insertion of the limiting protrusion 320.
[0055] In one embodiment, the limiting protrusion 320 is an arc-shaped protrusion.
[0056] In this embodiment, the arc-shaped protrusion facilitates insertion into the limiting groove 411.
[0057] In one embodiment, the limiting member 300 is detachably clamped in the two halves of the assembly 210.
[0058] In this embodiment, by setting the limiting member 300 to be detachably clamped in the two halves of the assembly 210, it can be disassembled separately and directly installed in the rotating part during assembly. When the assembly 210 is engaged with the locking structure 430, the assembly is more convenient. Moreover, since the limiting member 300 may be damaged due to frequent rotation, it is easy to replace and the maintenance cost is low.
[0059] In one embodiment, the limiting member 300 includes a fixing ring with a circular through hole, and clamping portions 310 are respectively provided on both sides of the fixing ring. The assembly 210 is provided with a clamping position 230 for mounting the clamping portions 310.
[0060] In this embodiment, during installation, the clamping position 230 is aligned with the clamping part 310 to install the assembly 210.
[0061] In one embodiment, the clamping portion 310 is a clamping block extending outward, and the outer side of the clamping block is provided with a chamfered shape;
[0062] The clamping position 230 includes a U-shaped support portion with an opening facing the first inclined surface 250.
[0063] In this embodiment, the outer side of the clamping block is set to a chamfered shape to facilitate alignment without requiring excessive precision.
