Description

Technical Field

[0001] The present invention relates to the technical field of styling devices, and in particular to a portable multi-functional styling device that can be used with real-time hovering and full-angle rotation. Background Art

[0002] A hair dryer is composed of a group of resistance wires and a high-speed motor. The high-speed motor is equipped with a fan blade for air supply. When powered on, the resistance wires generate heat, and the air blown by the fan passes through the resistance wires and becomes hot air. If only the small fan rotates and the resistance wires are not hot, then only air is blown out without heat.

[0003] In the current market, hair dryers are divided into fixed and portable types. The fixed type cannot be folded, rotated, or stored. The portable hair dryer is developed and promoted for the purpose of convenient storage. Basically, there are only two product forms: retracted and unfolded, which only serve the functions of storage and use. The existing portable hair dryers neither have a design for a 360° rotating usage scenario nor a practical scenario design for real-time hovering and immediate use. Users cannot adjust the air supply angle according to their own needs, making it inconvenient to use and resulting in a poor user experience.

[0004] In summary, there is a need for a portable multi-functional styling device that can be used with real-time hovering and full-angle rotation, which can improve the convenience of use and enhance the user experience. Summary of the Invention

[0005] The present invention aims to overcome the deficiencies of the existing portable hair dryers, which neither have a design for a 360° rotating usage scenario nor a practical scenario design for real-time hovering and immediate use. Users cannot adjust the air supply angle according to their own needs, making it inconvenient to use and resulting in a poor user experience. The present invention provides a portable multi-functional styling device that can be used with real-time hovering and full-angle rotation, which can improve the convenience of use and enhance the user experience.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A portable multi-functional styling device that can be used with real-time hovering and full-angle rotation, comprising: A main body housing; A protruding ring of the main body housing, provided on the main body housing; A handle housing; A protruding ring of the handle housing, provided on the handle housing, and the protruding ring of the handle housing and the protruding ring of the main body housing are mutually matched and rotatably connected; A rotating base, passing through the protruding ring of the handle housing and fixed to the main body housing, and the rotating base and the protruding ring of the handle housing are mutually matched and rotatably connected; A locator, which is installed at one end of the rotating base close to the handle housing; A plug-in part, which is arranged between the edge of the locator and the rotating base, and the locator and the rotating base are connected through the plug-in part; A rotating guide seat, which is fixed on the handle housing, and the rotating guide seat is installed at the end of the rotating base and is rotatably connected to it; A guide groove, which is arranged on the rotating guide seat and is located outside the locator, and the guide groove is rotatably connected to the locator; A positioning and hovering structure, which is arranged on the locator and is connected to the rotating guide seat.

[0007] During assembly, the main body housing is matched and installed with the handle housing through the guiding cooperation of the main body shell protruding ring and the handle shell protruding ring. The two can rotate 360° in all directions. The rotating base is inserted into the corresponding installation position on the main body housing through the handle shell protruding ring on the handle housing and is fixedly installed with the main body housing. The locator is plugged into one end of the rotating base close to the handle housing, and the two are installed and limited through the plug-in part so that they cannot rotate relative to each other. The rotating guide seat is fixedly installed with the handle housing, and the locator is located in the guide groove on the rotating guide seat. The locator can rotate 360° in all directions in the guide groove, and the positioning and hovering structure on the locator is connected to the rotating guide seat. When the handle housing rotates 360° in all directions relative to the main body housing, the rotating guide seat also rotates relative to the rotating base. At this time, the locator uses the positioning and hovering structure on it to perform real-time hovering control on the rotating guide seat, so that the handle housing can achieve the purpose of rotating 360° in all directions and hovering in real time when not in use, improving the convenience of use and enhancing the user experience effect.

[0008] Preferably, the locator includes an elastic base ring which is mounted on the rotary base. The elastic base ring is located inside the guide groove and rotatably connected thereto. The positioning and hovering structure includes positioning bumps provided on the outer side wall of the elastic base ring. A plurality of limiting grooves are provided on the inner wall of the guide groove, and the limiting grooves are evenly distributed in a ring shape about the central axis of the guide groove. The limiting grooves are engaged with the positioning bumps. A torsion retainer is mounted inside the elastic base ring, and the torsion retainer is provided with outer support arms which abut against the positioning bumps. During installation, the elastic base ring is mounted on one end of the rotary base close to the handle housing, and the two are limited from relative rotation through the insertion part. The torsion retainer (C-shaped) is mounted inside the locator through deformation, and the outer support arms (the two end parts of the C-shaped) thereon always abut against the positioning bumps on the elastic base ring and elastically support outward. When the handle housing rotates 360° in all directions relative to the main body housing, the rotary guide seat also rotates relative to the rotary base. At this time, the elastic base ring deforms to make the positioning bumps thereon slide into or out of the limiting grooves on the inner wall of the guide groove, so that the elastic base ring can be engaged with the rotary guide seat after rotating a fixed angle. And because the outer support arms on the torsion retainer always elastically support the positioning bumps on the elastic base ring outward, a force is generated on the rotary guide seat, forming a damping hovering effect. The rotary guide seat can rotate 360° in all directions and stop in the air in real time when the positioning bumps do not enter the limiting grooves, improving the use convenience and enhancing the user experience effect.

[0009] Preferably, a circular step is provided on the rotary base. The circular step is located at one end of the rotary base close to the handle housing. The elastic base ring is sleeved at the circular step. A radial chute is provided on the table surface of the circular step. The insertion part includes a locator convex block provided on the end surface of the elastic base ring. The locator convex block is inserted into the radial chute and is radially slidably connected thereto. The locator convex block is fixed on the positioning bump. After the elastic base ring is sleeved onto the circular step, it is installed by inserting the locator convex block thereon into the radial chute on the circular step. When the rotary guide seat rotates relative to the rotary base, the deformation when the positioning bump slides into or out of the limiting groove will drive the locator convex block to perform radial linear sliding in the radial chute, thereby completing the control of the rotation guidance and limitation between the handle housing and the main body housing and improving the motion accuracy.

[0010] Preferably, the material of the locator is plastic. Generally, POM material is used for manufacturing. It deforms under the action of external force due to the elasticity of the plastic and returns to its original state when there is no external force.

[0011] Preferably, the locator includes a positioning ring body. A locator moving groove is provided on the rotating base. One end of the positioning ring body is installed in the locator moving groove. The plugging portion includes an outer limiting convex block provided on the outer wall of the positioning ring body. An axial limiting sliding groove matching the outer limiting convex block is provided on the inner wall of the locator moving groove. One end of the positioning ring body is plugged in the locator moving groove through the cooperation of the outer limiting convex block and the axial limiting sliding groove and is axially slidably connected thereto. The bottom surface of the locator moving groove and one end surface of the positioning ring body are connected by a spring. The other end of the positioning ring body is installed in the guiding groove and is movably connected thereto. The positioning hovering structure includes a first ring gear. The first ring gear is provided on the end surface of the other end of the positioning ring body. A second ring gear matching the first ring gear is provided on the bottom surface of the guiding groove. The first ring gear and the second ring gear are engaged. During installation, the spring is placed in the locator moving groove on the rotating base. One end of the positioning ring body is plugged in the locator moving groove through the cooperation of the outer limiting convex block and the axial limiting sliding groove (the positioning ring body can axially slide in the locator moving groove but cannot rotate relatively). The other end of the positioning ring body is located in the guiding groove. At this time, the first ring gear on the positioning ring body is pressed against the second ring gear on the bottom surface of the guiding groove under the elastic force of the spring, and the positioning and locking are carried out through the engagement of the first ring gear and the second ring gear. When the handle housing rotates 360° in all directions relative to the main body housing, the rotating guiding seat also rotates relative to the rotating base. At this time, as long as the applied torque is greater than the static locking force, the engaged tooth positions between the two can enter the next one, thereby completing the 360° all-direction rotation and the real-time hovering stop.

[0012] Preferably, a spring seat is installed in the locator moving slot. A rib is fixed on the bottom surface of the locator moving slot. One end of the spring seat is provided with an axial slot matching the rib. The spring seat is installed at the bottom of the locator moving slot through the cooperation of the axial slot and the rib. The positioning ring body is sleeved on the other end of the spring seat. The spring is arranged between the spring seat and the positioning ring body. An inner limiting projection is fixed on the inner wall of the positioning ring body. An axial limiting sliding hole matching the inner limiting projection is arranged on the spring seat. The positioning ring body is installed on the spring seat through the cooperation of the inner limiting projection and the axial limiting sliding hole and is axially slidably connected thereto. During installation, first assemble the spring seat, the spring, and the positioning ring body into a small component. After the spring is installed on the spring seat, the positioning ring body is then installed on the spring seat through the cooperation of the inner limiting projection and the axial limiting sliding hole. At this time, the positioning ring body bounces outwards due to the rebounding force, and the inner limiting projection and the axial limiting sliding hole between the spring seat and the positioning ring body lock it, enabling the positioning ring body in the small component to be continuously affected by the spring. Then, insert the spring seat on the small component into the locator moving slot for installation. The axial slot on the spring seat and the rib on the bottom surface of the locator moving slot are positioned, thereby completing the overall installation of the small component. The axial movement of the positioning ring body is guided through the common cooperation of the outer limiting projection and the axial limiting sliding groove, and the inner limiting projection and the axial limiting sliding hole, further improving the movement accuracy of the positioning ring body.

[0013] Preferably, the handle housing includes a handle left shell and a handle right shell that match each other. The handle shell protruding ring is arranged on the handle left shell. The handle left shell and the handle right shell are snap-connected to each other. During assembly, first install the main body housing in matching with the handle left shell through the guiding cooperation of the main body shell protruding ring and the handle shell protruding ring. Then, install the omnidirectional rotation structure at the connection between the main body housing and the handle left shell. Finally, cover the handle right shell on the handle left shell and fasten it to complete all the assembly, improving the assembly convenience.

[0014] Preferably, a base threaded hole is arranged on the rotating base. A main body shell threaded hole matching the base threaded hole is arranged on the main body housing. The rotating base and the main body housing are fixedly connected by a first screw. During installation, align the base threaded hole of the rotating base with the main body shell threaded hole on the main body housing, and then tighten and fix it with the first screw. The connection method is simple and easy to operate, facilitating installation and disassembly, and reducing the difficulty of later maintenance and repair.

[0015] Preferably, a guide seat threaded hole is provided on the rotary guide seat, and a handle shell threaded hole matching the guide seat threaded hole is provided on the handle shell. The rotary guide seat and the handle shell are fixedly connected by a second screw. During installation, align the guide seat threaded hole of the rotary guide seat with the handle shell threaded hole on the handle shell, and then tighten and fix it with the second screw. The connection method is simple and easy to operate, facilitating installation and disassembly, and reducing the difficulty of later maintenance and repair.

[0016] Preferably, an annular boss is fixed on the outer side of the rotary base. The annular boss is located at one end of the rotary base close to the handle shell. The annular boss is located between the outer wall of the rotary base and the inner wall of the protruding ring of the handle shell. Several limiting ribs are fixed on the inner wall of the protruding ring of the handle shell. The limiting ribs are annularly distributed about the central axis of the protruding ring of the handle shell. The limiting ribs are located between the inner wall of the protruding ring of the handle shell and the outer wall of the rotary base. A gap is provided between the end face of the annular boss and the end of the limiting rib. After the rotary base is fixed, radial limitation is performed on the rotary base and the protruding ring of the handle shell through the annular boss and the limiting ribs, which can achieve the effect of balanced sliding without jamming during the relative rotation of the rotary base and the protruding ring of the handle shell, improving the smoothness of rotation. Moreover, there is a certain gap between the annular boss and the limiting ribs, which can meet the requirements of rotational movement.

[0017] Preferably, a wire duct is provided at the central position of the rotary base, and a wire duct through hole matching the wire duct is provided on the rotary guide seat. The wire duct is placed in the wire duct through hole and is rotatably connected thereto. The wires in the handle shell can be connected to the main body shell through the wire duct. Among them, the annular boss and the limiting ribs between the rotary base and the protruding ring of the handle shell form the first layer of rotary guidance, and the wire duct on the rotary base and the wire duct through hole on the rotary guide seat form the second layer of rotary guidance. Through the two-layer guidance structure, it is ensured that the handle shell and the main body shell slide evenly without jamming during rotation.

[0018] Preferably, a rotational clearance is provided between the rotary base and the protruding ring of the handle shell, and between the wire duct and the wire duct through hole. The rotational clearance is 0.05 mm to 0.15 mm on one side. Among them, the rotational clearance between the annular boss on the outer side of the rotary base and the inner wall of the protruding ring of the handle shell is 0.1 mm on one side, and the rotational clearance between the limiting ribs on the inner side of the protruding ring of the handle shell and the outer wall of the rotary base is 0.1 mm on one side; among them, the rotational clearance between the outer wall of the wire duct and the hole wall of the wire duct through hole is 0.1 mm on one side. Through the design of the rotational clearance of the two-layer guidance structure, it is further ensured that the handle shell and the main body shell slide evenly without jamming during rotation.

[0019] Preferably, two wire harness limiting columns are fixed on the rotary guide seat. The wire harness limiting columns are placed on the side of the through hole of the wire duct. A pressing plate is also fixed between the ends of the two wire harness limiting columns. The pressing plate and the two wire harness limiting columns jointly form a wire routing space. The two wire harness limiting columns position the wire harness coming out of the wire hole, and then the pressing plate fixes the wire harness, improving the constraint effect on the wire harness and keeping the wire harness inside the handle housing fixed when the whole machine rotates.

[0020] The beneficial effects of the present invention are as follows: It can achieve 360° full-angle rotation and stop in suspension in real time, improving the convenience of use and enhancing the user experience effect; there is rotation guidance and control when the main body housing and the handle housing rotate relative to each other, improving the motion accuracy; the positioner has excellent resilience, is not prone to permanent deformation, and at the same time has strong tear resistance and is not easy to break; when the main body housing and the handle housing rotate relative to each other, the sliding is balanced and there is no jamming, improving the smoothness of rotation; the assembly convenience is improved; the connection method is simple and easy to operate, facilitating installation and disassembly, and reducing the difficulty of later maintenance and repair; the constraint effect on the wire harness is improved.

The wire pressing plate 26 and the two wire harness limiting posts 25 together form a wire routing space.

[0037] Assembly process of the first technical solution of the present invention: 1. The main body housing 1 is matched and installed with the left handle housing 14 through the guiding cooperation of the protruding ring opening 2 of the main body housing and the protruding ring opening 4 of the handle housing; 2. The rotary base 5 is inserted into the corresponding installation position on the main body housing 1 through the protruding ring opening 4 on the left handle housing 14 and is fixedly installed with the main body housing 1 by the first screw 16 (radial limiting is performed between the rotary base 5 and the protruding ring opening 4 of the handle housing through the annular boss 17 and the limiting rib 18, which can achieve the effect of balanced sliding without jamming during the relative rotation between the rotary base 5 and the protruding ring opening 4 of the handle housing, and there is a certain gap between the annular boss 17 and the limiting rib 18 to meet the requirements of the rotational movement); 3. The elastic base ring 7 is sleeved onto the annular step 19 of the rotary base 5 and is installed by inserting the positioning protrusion 21 thereon into the radial sliding groove 20 on the annular step 19; 4. The torque retainer 12 (C-shaped) is installed inside the elastic base ring 7 through deformation, and the outer support arms 13 (the two ends of the C-shaped) on it always abut against the positioning convex points 8 on the elastic base ring 7 and elastically support outward; 5. The rotary guiding seat 9 and the handle housing 3 are fixedly installed by the second screw 22, and the elastic base ring 7 is located in the guiding groove 10 on the rotary guiding seat 9; 6. The right handle housing 15 is covered on the left handle housing 14 and fastened and fixed.

[0038] Principle of real-time hovering and full-angle rotation of the first technical solution of the present invention: When the handle housing 3 rotates relative to the main body housing 1, the rotary guide seat 9 also rotates relative to the rotary base 5. At this time, the elastic base ring 7 deforms so that the positioning bumps 8 thereon slide into or out of the limiting grooves 11 on the inner wall of the guide groove 10 (the deformation when the positioning bumps 8 slide into or out of the limiting grooves 11 will drive the positioner bump 21 to slide linearly in the radial chute 20, thereby completing the control of the rotation guidance and limitation between the handle housing 3 and the main body housing 1), enabling the elastic base ring 7 to be clamped with the rotary guide seat 9 after rotating a fixed angle. Moreover, since the outer support arm 13 on the torque retainer 12 always elastically supports the positioning bumps 8 on the elastic base ring 7 outward, generating a force on the rotary guide seat 9 to form a damping hovering effect, the rotary guide seat 9 can achieve 360° full-angle rotation and stop in the air in real time when the positioning bumps 8 do not enter the limiting grooves 11.

[0039] Assembly process of the second technical solution of the present invention: I. The main body housing 1 is matched and installed with the left handle housing 14 through the guiding cooperation of the main body housing protruding ring mouth 2 and the handle housing protruding ring mouth 4; II. The rotary base 5 is inserted into the corresponding installation position on the main body housing 1 through the handle housing protruding ring mouth 4 on the left handle housing 14 and fixedly installed with the main body housing 1 through the first screw 16 (radial limitation is performed between the rotary base 5 and the handle housing protruding ring mouth 4 through the annular boss 17 and the limiting rib 18, which can achieve a smooth sliding effect without jamming during the relative rotation process between the rotary base 5 and the handle housing protruding ring mouth 4, and there is a certain gap between the annular boss 17 and the limiting rib 18 to meet the requirements of rotational movement); III. The spring seat 32, the spring 29, and the positioning ring body 6 are assembled together as a sub-assembly. After the spring 29 is installed on the spring seat 32, the positioning ring body 6 is then installed on the spring seat 32 through the cooperation of the inner limiting bump 35 and the axial limiting sliding hole 36. At this time, the positioning ring body 6 bounces outward due to the rebound force, and the inner limiting bump 35 and the axial limiting sliding hole 36 between the spring seat 32 and the positioning ring body 6 can buckle, enabling the positioning ring body 6 in the sub-assembly to be continuously affected by the spring; IV. The spring seat 32 on the sub-assembly is inserted into the positioner movable slot 27 for installation. The axial slot 34 on the spring seat 32 and the rib 33 on the bottom surface of the positioner movable slot 27 are positioned. One end of the positioning ring body 6 is inserted into the positioner movable slot 27 through the cooperation of the outer limiting bump 28 and the axial limiting chute 37 (the positioning ring body 6 can slide axially in the positioner movable slot 27 but cannot rotate relatively); V. The rotary guide base 9 and the handle housing 3 are fixedly installed by the second screw 22, and the other end of the positioning ring body 6 is located in the guide groove 10 on the rotary guide base 9. The first ring teeth 30 on the positioning ring body 6 are pressed against the second ring teeth 31 on the bottom surface of the guide groove 10 under the elastic force of the spring 29, and the two are positioned and locked through the engagement of the first ring teeth 30 and the second ring teeth 31; VI. Cover the right handle shell 15 onto the left handle shell 14 and fasten them.

[0040] Principle of real-time hovering and full-angle rotation of the second technical solution of the present invention: When the handle housing 3 rotates relative to the main body housing 1, the rotary guide base 9 also rotates relative to the rotary base 5. At this time, as long as the applied rotational torque is greater than the static locking force, the tooth position engaged between the first ring teeth 30 and the second ring teeth 31 can enter the next position, thereby completing a 360° full-angle rotation and real-time hovering stop for use.

[0041] Among them, the annular boss 17 and the limiting rib 18 between the rotary base 5 and the protruding ring opening 4 of the handle shell form the first layer of rotary guidance (the rotational clearance is 0.1 mm on one side). The wire routing tube 23 on the rotary base 5 and the wire routing tube through hole 24 on the rotary guide base 9 form the second layer of rotary guidance (the rotational clearance is 0.1 mm on one side). Through the two-layer guidance structure, the handle housing 3 and the main body housing 1 can slide evenly without jamming during rotation.

[0042] The wire harness coming out of the wire routing hole is positioned by two wire harness limiting posts 25, and then fixed by the wire pressing plate 26, so that the wire harness inside the handle housing 3 can remain stationary when the whole machine rotates.
