[0040] The present utility model includes the following embodiments.

[0041] like Figures 1 to 3 As shown, the present invention provides a portable multifunctional fan 100, comprising a handheld handle 10 and a blowing unit 20 provided at one end of the handheld handle 10. The handheld handle 10 enables a user to handhold the fan, while the blowing unit 20 can quickly flow air through a power structure to blow out wind to cool the user.

[0042] Preferably, in this embodiment, a battery 11 and a control circuit board 12 are provided in the handheld rod 10. The battery 11 is electrically connected to the control circuit board 12. The battery 11 supplies power to electronic components in the fan 100, such as motors, and the control circuit board 12 controls the start and stop of the motor to control the normal operation of the fan 100.

[0043] In this embodiment, a charging port 13 is provided on the handheld pole 10. The charging port 13 is electrically connected to the control circuit board 12. The charging port 13 is connected to an external power source to charge the battery 11. The charging process is controlled by the control circuit board 12.

[0044] In this embodiment, a control button 14 is further provided on the handle 10. The control button 14 is electrically connected to the control circuit board 12, and the control button 14 is used to control the start and stop of the fan, gear adjustment, etc.

[0045] like Figure 2 and Figure 3 As shown, the blowing unit 20 of the fan 100 of the present invention includes a cylinder housing 30, a motor 40 disposed in the cylinder housing 30, and a fan blade 50 rotatably connected to the motor 40. An air inlet 21 is provided at the rear end of the cylinder housing 30, and an air outlet 22 is provided at the front end of the cylinder housing 30. When the motor 40 is powered on and rotated, the fan blade 50 is driven to rotate, and air enters the cylinder housing 30 from the air inlet 21 and flows out from the air outlet 22 under the push of the fan blade 50, forming a blowing effect.

[0046] The fan 100 of the present invention has an air cylinder housing 30 detachably connected to an aromatherapy box 60 at the rear air inlet 21. It is understood that in other embodiments, the air cylinder housing 30 may also be detachably connected to the air outlet 22 at the front end. The aromatherapy box 60 contains aromatherapy material to emit fragrance. When the aromatherapy box 60 is placed at the air inlet 21 or the air outlet 22 of the fan 100, the fan 100 can blow out air with fragrance, thereby changing the odor of the air blowing on the user, improving the local air environment, and making the air smelled by the user fragrant. This can suppress various odors in crowded environments, making it particularly suitable for use in crowded places such as subways, stadiums, and concerts.

[0047] At the same time, because the aromatherapy box 60 of the present invention is detachably connected to the air duct housing 30, the aromatherapy box 60 can be easily installed or removed. First, when the fragrance in the aromatherapy box 60 is used up, it can be replenished and replaced in time. Second, the user can replace the aromatherapy box 60 with a different fragrance according to their own preferences. Third, when the user does not want to use the aromatherapy effect, the aromatherapy box 60 can be easily removed. The detachable connection of the present invention can be a plug-in connection, a snap connection, or a magnetic connection.

[0048] The portable multifunctional fan 100 of the present invention can not only blow air to cool down, but also improve the local air odor, thereby enhancing and improving the function of the fan 100 and promoting its application.

[0049] As an implementation method, Figures 1 to 3As shown, the aromatherapy box 60 of this embodiment is magnetically connected to the air inlet 21 at the rear end of the hair dryer shell 30. The magnetic connection makes it very convenient to assemble and disassemble the aromatherapy box 60 and the hair dryer shell 30, and there is no need to design a special connection structure on the surface of the aromatherapy box 60 and the hair dryer shell 30, which makes the packaging product beautiful.

[0050] Furthermore, a cooling fin assembly 70 is provided at the air outlet 22 at the front end of the fan housing 30. The cooling fin assembly 70 has a cooling effect, thereby cooling the air around the air outlet 22, thereby enabling the fan 100 to blow out cool air and improving the cooling effect of the fan 100. The cooling fin assembly 70 can use semiconductor cooling fins for cooling.

[0051] Specifically, if Figure 4 and Figure 5 As shown, the aromatherapy box 60 includes a first box body 61 and a second box body 62 that are detachably connected, an aromatherapy sheet 63 disposed between the first and second boxes 61, 62, and a first magnetic member 64 mounted within the second box body 62. The aromatherapy sheet 63 is made of a sheet of aromatherapy material, and the first and second boxes 61, 62 are detachably connected to facilitate easy access.

[0052] Preferably, in this embodiment, Figure 5 As shown, the end faces and side faces of the first and second housings 61, 62 are hollowed out to form a plurality of vents 65. In other words, in this embodiment, the vents 65 are provided not only on the end faces of the first and second housings 61, 62, but also on the side faces of the end faces of the first and second housings 61, 62. This allows the fragrance of the aromatherapy sheet 63 to escape from more vents 65 and mix with the air at the air inlet 21, thereby increasing the contact area and enhancing the aroma effect of the air.

[0053] The air duct housing 30 of this embodiment includes a cylinder 31, a rear cover 32 provided at the rear end of the cylinder 31, and a front cover 33 provided at the front end of the cylinder 31. The air inlet 21 is provided on the rear cover 32, and the air outlet 22 is provided on the front cover 33. A second magnetic member 34 is provided in the rear cover 32. Figure 4 As shown in FIG, the second box body 62 is tightly attached to the rear cover 32, and the first magnetic member 64 is attracted to the second magnetic member 34. That is, the aromatherapy box 60 is fixed to the air dryer housing 30 by the attraction between the first magnetic member 64 and the second magnetic member 34. In this embodiment, at least one of the first magnetic member 64 and the second magnetic member 34 is a magnet, and the other can be a metal that can be attracted to a magnet, such as iron or nickel, or the other can also be a magnet.

[0054] like Figure 6As shown, the second box body 62 includes a box ring 621 with an insertion wall 624, a first contact surface 622 located on the side of the box ring adjacent to the rear cover, and a plurality of circumferentially distributed external convex ribs 623 connecting the box ring 621 and the first contact surface 622. The insertion wall 624 allows the second box body 62 to be plugged into the first box body 61, facilitating disassembly between the two to replace the aromatherapy sheet 63 in the box body. Figure 6 As shown in FIG, the outer convex ribs 623 make the first fitting plane 622 protrude from the front end of the second box body 62 , and a vent 65 is provided between two adjacent outer convex ribs 623 .

[0055] like Figure 7 As shown, the rear cover 32 includes a cover body 321, a second mating plane 322 located in the middle of the rear end of the cover body 321, and a plurality of circumferentially distributed inwardly extending concave ribs 323 connecting the second mating plane 322 and the cover body. A gap is provided between adjacent inwardly extending concave ribs 323, and these gaps together form the air inlet 21. In this embodiment, the inward curvature of the end of the inwardly extending rib 323 that connects to the second mating plane 322 increases, forming the inwardly extending rib 323.

[0056] The inward-concave rib 323 makes the second fitting plane 622 retract inwardly to the center of the rear end of the cover body 321, thereby forming a concave structure in the center of the rear cover 32. Figure 4 As shown, the first fitting plane 622 fits with the second fitting plane 322 , and each of the outer convex ribs 623 is aligned with one of the inner concave ribs 323 , and the concave and convex curvatures match.

[0057] The alignment of the first mating plane 622 and the second mating plane 322 ensures a larger, more stable contact area between the aromatherapy box 60 and the rear cover 32 of the hair dryer housing 30 after magnetic connection, thereby enhancing the stability of the magnetic connection. Furthermore, after magnetic connection, each convex rib 623 of the aromatherapy box 60 aligns with the corresponding concave rib 323 of the rear cover 32 of the hair dryer housing 30, and the convex and concave curvatures match. This effectively embeds the front end of the aromatherapy box 60 into the recess of the rear cover 32, further enhancing the secureness of the magnetic connection. Furthermore, this embedded structure reduces the protrusion of the aromatherapy box 60 from the rear cover 32 after magnetic connection, enhancing aesthetics.

[0058] Please continue to refer to Figures 2 to 4 In this embodiment, a fan bracket 80 is provided in the wind tube housing 30 of the fan 100. The motor 40 and the fan blades 50 are sequentially provided at the rear end of the fan bracket 80. A plurality of air ducts 82 are circumferentially passed through the periphery of the fan bracket 80. The air ducts 82 connect the air inlet 21 and the air outlet 22.

[0059] The fan bracket 80 is a cylindrical structure with a central column structure for mounting the motor 40 and cooling fin assembly 70. Multiple baffles 81 are spaced circumferentially around the periphery of the cylindrical structure. The tops of these baffles 81 are mounted on the cylinder 31, and the gaps between these baffles 81 form an air duct 82. Air enters through the air inlet 21, is driven by the fan blades 60, and rapidly passes through the air duct 82 before being discharged from the air outlet 22, creating a blowing effect.

[0060] The refrigeration fin assembly 70 of this embodiment includes a heat dissipation bracket 71, a refrigeration mounting frame 72, a refrigeration fin 73 and an end cover 74. The heat dissipation bracket 71 is installed at the front end of the fan bracket 80, the refrigeration mounting frame 72 is fixed to the front end of the heat dissipation bracket 71, the refrigeration fin 73 is fixed on the refrigeration mounting frame 72 and the refrigeration fin 73 is in contact with the front end of the heat dissipation bracket 71, and the end cover 74 is installed at the front end of the refrigeration mounting frame 72 and covers the refrigeration fin 73.

[0061] The cooling fin 73 is electrically connected to the control circuit board 12 and utilizes a thermoelectric semiconductor cooling module. The front end of the cooling fin 73 serves as a cooling surface, while the rear end serves as a heating surface. To dissipate heat generated at the rear end of the cooling fin 73, this embodiment incorporates a heat dissipation bracket 71 that is bonded to the cooling fin 73. Furthermore, the heat dissipation bracket 71 is bonded to the fan bracket 80. Heat transferred from the cooling fin 73 to the heat dissipation bracket 71 can be rapidly discharged through the air duct 82 of the fan bracket 80 with the rapidly flowing air, thereby improving heat dissipation efficiency. An end cap 74 protects the cooling fin 73.

[0062] The portable multifunctional fan 100 of this embodiment is provided with an aromatherapy box 60 at the rear end of the wind tube housing 30, so that the wind blown out by the fan 100 has fragrance, thereby improving the local air odor. At the same time, by providing a cooling plate assembly 70 at the front end of the wind tube housing 30, the fan 100 can blow out cool wind below the ambient temperature, thereby improving the cooling effect of the fan 100. The fan 100 of this embodiment has multiple functions, which enhance the user experience of using the fan 100 of the utility model.

[0063] The above description is merely an example to clearly illustrate the present invention and does not limit the patent scope of the present invention.
