[0078] The high-speed hair dryer of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0079] Reference Figures 1 to 8 As shown, the high-speed hair dryer provided according to the embodiment of the present utility model includes a blower 10, a heating element 20, a blowing element 30, and a handle 40.

[0080] The air duct 10 includes a front duct 11, a middle duct 12, and a rear duct 13, which are interconnected. The front duct 11 has an air outlet 111 at its front end. The heating element 20 is disposed within the front duct 11 and is used to heat the air. The blowing element 30 is disposed within the rear duct 13 and is used to blow air toward the heating element 20 and blow the heated air out through the air outlet 111.

[0081] The main structure of the hair dryer consists of a blower tube 10, a heating element 20, and a blower assembly 30. The blower tube 10 includes a front tube 11, a middle tube 12, and a rear tube 13, which are interconnected to form an air duct for easy airflow. The heating element 20 is located inside the front tube 11, at the air outlet 111 at its front end, to heat the air. The blower assembly 30 is located at the rear end of the rear tube 13, drawing air from the rear end into the rear tube 13 and blowing it towards the heating element 20. This allows the blower assembly 30 to continuously supply air to the heating element 20, which heats the air before it is blown out through the air outlet 111, allowing the user to dry their hair. The structure of the heating element 20 is generally the same as that of existing hair dryers, therefore its specific construction will not be described in detail in this embodiment.

[0082] The handle portion 40 includes a rotating base 41, a positioning rotating component 42, and a handle 43. The rotating base 41 is disposed at the bottom of the middle cylinder 12, and an elastic positioning ring 412 is provided on the rotating base 41. Multiple slots 4121 are evenly spaced on the inner wall of the elastic positioning ring 412. The positioning rotating component 42 is disposed within the elastic positioning ring 412, and multiple locking blocks 421 are evenly spaced on the outer peripheral wall of the positioning rotating component 42. The multiple locking blocks 421 respectively engage with the multiple slots 4121. Inside 121, two driving blocks 422 are arranged opposite each other on the positioning rotating member 42; a pivot groove 431 is provided at the upper end of the handle 43, and the rotating seat 41 is rotatably disposed in the pivot groove 431 so that the handle 43 can switch between a vertical position and a parallel position relative to the air duct 10; two fixing grooves 433 are arranged opposite each other on one side of the groove wall of the pivot groove 431, and the two driving blocks 422 on the positioning rotating member 42 are respectively locked and fixed in the two fixing grooves 433;

[0083] When the handle 43 switches between the vertical position and the parallel position, the handle 43 can drive the positioning rotating member 42 to rotate within the rotating seat 41 through the two driving blocks 422, so as to force the plurality of locking blocks 421 on the positioning rotating member 42 to engage in the locking slots 4121 at different positions.

[0084] The handle 40 is located at the bottom of the middle tube 12 for the user to hold and operate the hair dryer. Specifically, it includes a rotating base 41, a positioning rotating component 42, and a handle 43. The rotating base 41 is fixedly located at the bottom of the middle tube 12 and is rotatably connected to the pivot groove 431 at the upper end of the handle 43, switching between a vertical and a folded position. When the handle 43 is rotated to a vertical position relative to the hair tube 10, it is in the use position, allowing the user to hold the handle 43 and use the hair dryer. When the handle 43 is rotated to a parallel position relative to the hair tube 10, it is in the folded position, allowing the user to fold and store the hair dryer, reducing its space requirements. Specifically, an elastic positioning ring 412 is provided inside the rotating seat 41. The elastic positioning ring 412 has a certain elasticity and can undergo elastic deformation. Multiple slots 4121 are provided on the inner wall of the elastic positioning ring 412. In this embodiment, there are four slots 4121, which are evenly spaced, with an included angle of 90° between adjacent slots 4121. The positioning rotating component 42 is disposed inside the elastic positioning ring 412, and multiple locking blocks 421 are provided on its outer peripheral wall. In this embodiment, there are also four locking blocks 421, which are evenly spaced, with an included angle of 90° between adjacent blocks 421. The four locking blocks 421 can be respectively locked into the four slots 4121. Simultaneously, two driving blocks 422 are provided on the positioning rotating component 42 to drive... Block 422 can be locked into the fixing groove 433 on the inner wall of the pivot groove 431. In this way, when the handle 43 switches between the vertical position and the parallel position, that is, when the handle 43 switches from the position perpendicular to the air duct 10 to the position parallel to the air duct 10, or when the handle 43 switches from the position parallel to the air duct 10 to the position perpendicular to the air duct 10, the handle 43 can drive the two drive blocks 422 and the positioning rotating member 42 to rotate together. Since the elastic positioning ring 412 has a certain elasticity and can produce elastic deformation, the four locking blocks 421 on the positioning rotating member 42 can rotate out from the four locking slots 4121 in the four elastic positioning rings 412, and after rotating 90°, they can re-lock into the corresponding locking slots 4121 and remain in that position. Accordingly, the handle 43 is not easy to rotate.In other words, the handle 43 can be switched from a vertical position to a parallel position, and vice versa. After switching, the handle 43 drives the four locking blocks 421 on the positioning rotating part 42 to engage in the four slots 4121 on the elastic positioning ring 412. Therefore, the handle 43 remains in this position and is not easily rotated. In this way, the user can pick up the hair dryer when the handle 43 is switched to the vertical position. After use, the handle 43 is rotated 90° to the parallel position. At this time, the handle 43 will drive the four locking blocks 421 on the positioning rotating part 42 to engage in the four slots 4121 on the elastic positioning ring 412 and rotate out. After rotating 90°, they will re-engage in the corresponding slots 4121, thus keeping the handle 43 in this position. The handle 43 can be folded at the bottom of the blower tube 10, thereby reducing the size of the entire hair dryer and reducing the space occupied by the hair dryer, making it convenient for storage and carrying.

[0085] According to the high-speed hair dryer provided by this utility model, the handle part 40 can be folded relative to the blower tube 10, thereby reducing the space occupied by the hair dryer and making it convenient to store and carry.

[0086] Advantageously, in one embodiment of the present invention, a locking component 50 is further included, the locking component 50 including a locking block 51, a sliding seat 52 and a slider 53; two locking blocks 51 are provided, and the two locking blocks 51 are disposed opposite to each other on the rotating seat 41; the sliding seat 52 is disposed on the handle 43; the slider 53 is slidably disposed in the sliding seat 52, and can be engaged between the two locking blocks 51 when the handle 43 is switched to the vertical position, so as to lock the handle 43.

[0087] The locking component 50 is used to lock the handle 43 when it is rotated to the vertical position, preventing the handle 43 from rotating and thus facilitating the user's grip on the handle 43 for use. It includes a locking block 51, a sliding seat 52, and a slider 53. Two locking blocks 51 are provided, positioned opposite each other on the rotating seat 41 and rotating with it. A locking gap exists between the two locking blocks 51. The sliding seat 52 and slider 53 are both located on the handle 43, and the sliding seat 52 guides the slider 53, allowing it to slide up and down along the sliding seat 52. When the handle 43 is switched to the vertical position, the slider slides into the locking gap. Thus, the slider 53 blocks the two locking blocks 51, preventing them from rotating, and consequently, the rotating seat 41 also cannot rotate. This locks the handle 43 and the rotating seat 41, preventing them from rotating and facilitating user operation. After the user finishes using the device, slide the slider 53 out of the locking gap, and the handle 43 and the rotating seat 41 can rotate relative to each other, thereby allowing the handle 43 to be folded.

[0088] Advantageously, in one embodiment of the present invention, the rotating seat 41 is provided with a mounting groove 411, and a plurality of limiting grooves 4111 are evenly spaced on the inner wall of the mounting groove 411.

[0089] The elastic positioning ring 412 has a plurality of limiting blocks 4122 evenly spaced on its outer peripheral wall. The plurality of limiting blocks 4122 are fixedly installed in the plurality of limiting grooves 4111 respectively, and there is a gap 413 between the outer peripheral wall of the elastic positioning ring 412 and the inner wall of the mounting groove 411.

[0090] In this embodiment, the mounting groove 411 is a circular groove with four limiting grooves 4111 on its inner wall. Correspondingly, the elastic positioning ring 412 is also generally circular, with four limiting blocks 4122 on its outer peripheral wall. The elastic positioning ring 412 is made of elastic silicone or other elastic materials. The four limiting blocks 4122 are fixedly installed in the four limiting grooves 4111, thus preventing the elastic positioning ring 412 from shifting within the mounting groove 411. A gap 413 exists between the outer peripheral wall of the elastic positioning ring 412 and the inner wall of the mounting groove 411. When the handle 43 is turned to drive the positioning rotating member 42 to rotate, the multiple locking blocks 421 on the outer peripheral wall of the positioning rotating member 42 rotate out of the current position's slot 4121, which can force the elastic positioning ring 412 to undergo a certain deformation until the multiple locking blocks 421 rotate into different positions' slots 4121. The gap 413 is set to reserve a certain space for the deformation of the elastic positioning ring 412, so that the multiple locking blocks 421 can rotate smoothly from the current slot 4121 to other positions' slots 4121, so as to lock the handle 43.

[0091] Advantageously, in one embodiment of the present invention, the rotating seat 41 is provided with a pivot hole, the elastic positioning ring 412 is provided around the pivot hole, the positioning rotating member 42 is provided in the mounting groove 411 and is located between the pivot hole and the elastic positioning ring 412, and the two driving blocks 422 are respectively provided on both sides of the pivot hole;

[0092] A rotating shaft 432 is provided in the pivot groove 431. The rotating shaft 432 is rotatably inserted into the pivot hole. The two fixing grooves 433 are respectively provided on both sides of the rotating shaft 432.

[0093] In other words, the rotating base 41 and the handle 43 are connected by the rotating shaft 432, and are automatically locked by the cooperation of the elastic positioning ring 412 and the positioning rotating part 42. This makes it convenient for users to rotate the handle 43 to different positions and lock it according to their needs, making the operation very convenient.

[0094] Advantageously, in another embodiment of the present invention, the inner wall of the elastic positioning ring 412 has an arc-shaped transition between two adjacent slots 4121.

[0095] Thus, when the handle 43 is turned to drive the positioning rotating member 42 to rotate, the locking block 421 on the outer peripheral wall of the positioning rotating member 42 rotates out of the current position slot 4121 and can more smoothly follow the arc transition part on the inner wall of the elastic positioning ring 412 to be locked into the other position slot 4121, thereby locking the handle 43 so that the handle 43 is kept in the position after rotation.

[0096] Advantageously, in some embodiments of the present invention, a nozzle 112 is provided at the front end of the front cylinder 11, and the nozzle 112 is detachably inserted into the air outlet 111.

[0097] The nozzle 112 has a flat structure, which can concentrate the airflow and help users better control the airflow of the hair dryer, making it easier to style hair. Secondly, the nozzle 112 can protect the user from direct contact with the air outlet of the hair dryer during use, reducing the risk of burns. Finally, the nozzle 112 can enhance the overall appearance of the hair dryer, making it more stylish and attractive.

[0098] Advantageously, in some embodiments of the present invention, the blower assembly 30 includes a fan blade 32 and a drive member 31;

[0099] The drive component 31 is located at the rear end of the rear cylinder 13 and is connected to the fan blade 32. It is used to drive the fan blade 32 to rotate, thereby drawing in the air at the rear end of the rear cylinder 13 and blowing it toward the heating component 20.

[0100] The drive unit 31 can be a high-speed motor that can rotate quickly, thereby driving the fan blade 32 to rotate at a high speed to draw air into the blower and blow it toward the heating element 20 and the air outlet 111.

[0101] Advantageously, in some other embodiments of the present invention, a rear cover 131 is provided at the rear end of the rear cylinder 13, the rear cover 131 is detachably connected to the rear end of the rear cylinder 13, and a dustproof net (not shown in the figure) is provided inside the rear cover 131, the dustproof net being detachably snapped into the rear cover 131.

[0102] The rear cover 131 is used to install a dust filter at the rear end of the blower assembly 30. This allows the air drawn in by the blower assembly 30 to be filtered through the dust filter, while also preventing dust or other impurities in the air from being drawn into the blower.

[0103] Advantageously, in some other embodiments of the present invention, a plasma generator (not shown in the figure) is also included, which is disposed on the heating component 20 inside the front cylinder 11 for generating plasma.

[0104] Of course, in other embodiments, a negative ion generator can also be used to produce negative ions. In this way, by setting up a plasma or negative ion generator, plasma or negative ions can be generated and then blown onto the user's hair along with heated air. This can neutralize static electricity on the hair, and can even smooth frizz, close the hair cuticles, and make the hair look shinier. At the same time, it can prevent the generation of static electricity, which is beneficial to protecting the user's hair quality.

[0105] Advantageously, in some other embodiments of the present invention, a display screen is provided on the outer wall of the middle cylinder 12, and a semi-transparent cover 121 is provided on the outer wall of the display screen. A plurality of control buttons 122 are provided at the bottom of the semi-transparent cover 121, and the plurality of control buttons 122 include at least a wind speed adjustment button, a temperature adjustment button and a power on / off button.

[0106] The display screen can show relevant parameters such as temperature and fan speed in real time for easy viewing by the user. The display screen is covered by a semi-transparent cover 121, which not only makes it easy to view the display screen but also protects it from impacts. In addition, control buttons 122 are located at the bottom of the semi-transparent cover 121, allowing users to easily adjust relevant parameters such as temperature and fan speed for convenient use.

[0107] It should be added that a main control circuit board is disposed between the heating element 20 and the blowing element 30. This main control circuit board is connected to the heating element 20, the blowing element 30, and other related electronic components, and is used to control the operation of these components. By placing it between the heating element 20 and the blowing element 30, the blowing element 30 can dissipate heat from the main control circuit board, preventing it from overheating and burning out, thus extending its lifespan to some extent. The main control circuit board can be connected to a rechargeable battery inside the handle, and thus powered by the rechargeable battery, eliminating the need to plug in a power cord every time it is used.
