Description

Technical Field

[0001] The invention relates to a hair dryer, which is particularly suitable for drying hair, clothes and the like. Background Art

[0002] CN111227476B, WO2021026956A1, WO2021028062A1, and others disclose portable hair dryers comprising a main body and a deformable handle movably connected to the main body. These hair dryers are portable and easy to use, particularly allowing for quick switching between handheld and hands-free operation. However, these hair dryers still require further improvement to enhance their usability. Summary of the Invention

[0003] The object of the present invention is to provide a hair dryer that is more convenient to use.

[0004] The hair dryer according to the present invention comprises:

[0005] a main body having a receiving seat formed with a positioning recess; and

[0006] Handle, including:

[0007] Fixed plate;

[0008] a connector fixedly mounted on the fixing plate and removably received in the receiving seat of the main body;

[0009] at least one wing located below the joint, pivotally mounted on the fixed plate via a horizontal pivot formed on a top portion thereof, wherein the pivot is provided with an inward protrusion; and

[0010] A sliding pin is slidably mounted on the fixed plate and extends longitudinally through the joint toward the positioning recess of the receiving seat of the main body, wherein the sliding pin is provided with at least one bearing seat in which the inward protrusion on the pivot of the at least one wing is rotatably engaged.

[0011] The hair dryer of the present invention can be conveniently switched between a handheld mode and a hands-free mode. When the hair dryer is in the handheld mode, the wings of the handle pivot to their innermost position relative to the fixed plate, i.e., the wings close together, defining a tapered handle that is convenient for handholding, while the sliding pin simultaneously engages a positioning recess to prevent accidental rotation of the main body relative to the handle. When the hair dryer is switched from the handheld mode to the hands-free support mode, the wings pivot to their outermost position relative to the fixed plate, i.e., the wings open outward, defining an umbrella-shaped support handle or tripod that is convenient for positioning on a countertop, while the sliding pin simultaneously or automatically exits the positioning recess to allow free manual rotation of the main body relative to the support handle.

[0012] In addition, the hair dryer of the present invention can be switched to a hands-free hanging mode by adjusting the extension length of the sliding pin. In this mode, the wings of the handle can be pivoted relative to the fixed plate to an innermost position, that is, the wings are closed together to define a tapered handle that is convenient for insertion into the hanging receiving tube of the wall mount, while the sliding pin does not extend beyond the handle joint to allow free manual rotation of the main body relative to the hanging handle.

[0013] The hair dryer of the present invention is particularly flexible, convenient and reliable in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Figure 1 The hair dryer generally comprises a cylindrical body 1 and a tapered handle 2.

[0027] Figure 2 for Figure 1 A partial cross-sectional view of a portion of the main body 1 is shown. Figure 1 and Figure 2 As shown, the main body 1 has an outer peripheral surface 10 on which a receiving seat 11 is formed. A positioning recess 110 is formed in the central portion of the receiving seat 11. An annular magnet 12 surrounds the receiving seat 11 through a mounting seat 13 and is fixed behind the receiving seat 11. The receiving seat 11 has a spherical surface formed by a rubber membrane.

[0028] Figure 3 for Figure 1 An exploded schematic perspective view of the handle 2 is shown; Figure 4 for Figure 1 The cross-sectional view of the handle 2 is shown. Figure 3 and Figure 4 As shown, the handle 2 includes a fixed disk 20, a rounded end (ball head) 21, wings 22 (three shown), a sliding pin 23, and the like. The rounded end 21 is made of iron and is provided with a longitudinal through-hole formed by an upper portion 210 and a lower portion 211. The upper portion 210 of the through-hole has a smaller cross-section, while the lower portion 211 has a larger cross-section. Each wing 22 tapers downward, with a horizontal pivot 220 formed at the top. The pivot 220 is provided with an inwardly protruding rounded protrusion 221. A threaded blind hole 230, open at the lower end, extends into the sliding pin 23. The fixed disk 20 is provided with three circumferential receiving grooves 201 for pivotally receiving the corresponding pivots 220 of the wings 22, and a central longitudinal channel 202.

[0029] The handle 2 further includes a slider 24 , an adjusting screw 25 and a connecting piece 26 , wherein the slider 24 has a central longitudinal through hole 240 and three circumferential support seats 241 , the adjusting screw 25 has a threaded rod 251 , and the connecting piece 26 has a longitudinal through hole 260 and an insert 261 .

[0030] The positioning recess 110 of the receiving groove 11 of the main body 1, the upper portion 210 of the through hole of the round head end 21, the through hole 260 of the connecting member 26, and the through hole 240 of the slider 24 all have an elliptical cross-section that is substantially the same as that of the sliding pin 23, so that the sliding pin 23 can slide but not rotate therethrough.

[0031] The slider 24 is slidably but non-rotatably mounted in the channel 202 of the fixed disk 20. The protrusion 221 on the pivot 220 of the wing 22 is rotatably engaged in a corresponding bearing seat 241 of the slider 24. The threaded rod 251 of the adjustment screw 25 is threadedly engaged with the threaded blind hole 230 of the sliding pin 23 and extends through the through hole 240 of the slider 24. The adjustment screw 25 is fixed to the slider 24 by a retaining spring 252 so that it can rotate relative to the slider 24 but cannot be displaced.

[0032] The fixed disk 20 is fixedly connected to the rounded end 21 via the connecting member 26, wherein the insert 261 of the connecting member 26 is inserted into the lower portion 211 of the through hole of the rounded end 21 with a positive fit. The stop bar 231 passes through the sliding pin 23 laterally and abuts and stops on the top lower side of the insert 261 of the connecting member 26 as it moves upward with the sliding pin 23, thereby limiting the maximum length of the sliding pin 23 that can extend upward from the connecting member 26, and therefore limiting the maximum length of the sliding pin 23 that can extend upward from the rounded end 21.

[0033] An annular decorative plate 27 is further provided between the connecting member 26 and the round head end 21 .

[0034] Figure 5 FIG2 shows a partial cross-sectional view of a hair dryer in a handheld state according to the present invention, wherein the wings 22 are folded together to define a tapered handle 2 in a handheld state. Figure 5 It can be seen that the round head end 21 is magnetically positioned in the receiving groove 11, and the sliding pin 23 extends upward from the round head end 21 (about 2 mm) until it extends into the positioning recess 110 of the receiving groove 11 of the main body 1, thereby limiting the rotation of the main body 1 relative to the round head end 21 of the handle 2.

[0035] Figure 6 For the general Figure 5 The hair dryer is shown in a partial cross-sectional view when switched to the hands-free mode, with the wings 22 spread outward to define the umbrella-shaped support handle 2. The switching process is as follows: the wings 22 are manipulated to pivot outward, and the pivots 220 of the wings 22 rotate in the corresponding receiving slots 201 of the fixed plate 20. The protrusions 221 then rotate in the corresponding support seats 241 of the slider 24 and simultaneously pry the slider 24 downward until the sliding pin 23 is fully retracted into the rounded end 21, as shown in FIG. Figure 6 In this case, the main body 1 can be allowed to rotate manually relative to the rounded end 21 of the support handle 2.

[0036] When the general Figure 6 When the wings 22 of the support handle 2 are fully retracted, the hair dryer will return to the Figure 5 Shown in handheld state.

[0037] Figure 7A partial cross-sectional view of the hair dryer is shown in a different configuration, wherein the wings 22 are brought together to define the tapered handle 2. Figure 7 In the structure shown, the upward extension length of the sliding pin 23 is adjusted by manually rotating the adjusting screw 25 so that the sliding pin 23 does not extend out of the round head end 21 when the wings 22 are closed together, thereby allowing the main body 1 to be freely manually rotated relative to the round head end 21 of the handle 2. Figure 7 The hair dryer shown can be used for Figure 8 Wall mount bracket as shown. Figure 8 As shown, the wall mounting bracket 3 has a tapered receiving tube 30 at one end of a cantilever 31. Figure 7 The tapered handle 2 of the hair dryer shown can be inserted into the receiving tube 30 in a form-fitting manner and accommodated therein.

[0038] Figure 9 The hair dryer body 1 is shown with a power cord 40. Figure 10 The structure provided in the main body 1 to prevent the power cord from accidentally detaching is shown. As shown, the mounting base 13 of the main body 1 is connected to the electrical connector 14 within the main body 1 via a connecting plate 16. The end of the connecting plate 16 also has a slot 15 formed therein. The end of the power cord 40 is formed with an electrical interface 42 for receiving the electrical connector 14. A resilient snap 41 is also formed near the end of the power cord 40 for quickly snapping into the slot 15. Figure 11 In the illustrated structure, the electrical connector 14 is inserted into the electrical interface 42, and the buckle 41 is engaged with the slot 15. This structure allows the power cord 40 to be easily removed from the main body 1 manually while effectively preventing the power cord 40 from accidentally detaching from the main body 1.

[0039] Although not specifically shown, the hair dryer of the present invention may optionally include a tubular end cap, which is removably coupled to the rear end of the main body 1 for accommodating the handle 2 and the power cord 40 separated from the main body 1 and allowing the hair dryer to present a straight-cylinder structure as a whole when not in use, such as for storage or transportation.
