[0029] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0030] Example 1

[0031] As shown in Figures 1, 2, 3, 4 and 5, the present invention provides a hair styling tool, including a straight-tube hair dryer body 1 and a switching mechanism.

[0032] The hair dryer body 1 includes a housing 11, a fan motor 12, a control circuit board 13, and a heating element 14. The side wall of the housing 11 has a first air outlet 111 and a second air outlet 112, which are set at an angle α. A cavity 113 is formed inside the housing 11, selectively communicating with either the first air outlet 111 or the second air outlet 112. An air inlet 114 communicating with the cavity 113 is provided on the side wall of the housing 11. The fan motor 12, the control circuit board 13, and the heating element 14 are all disposed within the cavity 113, and both the fan motor 12 and the heating element 14 are electrically connected to the control circuit board 13. Specifically, 0° < α ≤ 90°.

[0033] The switching mechanism includes a movable component 2 and a driving component 3. The movable component 2 is disposed inside the blower body 1. The driving component 3 is disposed on the blower body 1 and connected to the movable component 2. The movable component 2 can block the first air outlet 111 or the second air outlet 112 under the drive of the driving component 3, so that the cavity 113 can selectively communicate with the first air outlet 111 or the second air outlet 112.

[0034] In this embodiment, the driving component 3 includes a knob 31, and the movable component 2 includes a rotating shaft 21, a driving gear 22, and a movable plate 23. The rotating shaft 21 is rotatably disposed inside the hair dryer body 1, and one end of the rotating shaft 21 is connected to the driving component 3. The driving gear 22 is sleeved on the rotating shaft 21. The movable plate 23 is movably disposed inside the hair dryer body 1, and the movable plate 23 is provided with a rack 24, which meshes with the driving gear 22. The movable plate 23 can block the first air outlet 111 or the second air outlet 112 under the drive of the knob 31, the driving gear 22, and the rack 24.

[0035] In practical application, if the first air outlet 111 is selected, rotating the knob 31 forward will drive the rotating shaft 21 to rotate, which in turn drives the drive gear 22 to rotate. The drive gear 22 drives the movable plate 23 to move via the rack 24, causing the movable plate 23 to block the second air outlet 112. External air enters the cavity 113 through the air inlet 114 and then is blown out through the first air outlet 111, thus achieving air outlet 111. If the second air outlet 112 is selected, rotating the knob 31 in reverse will drive the rotating shaft 21 to rotate in the opposite direction, which in turn drives the drive gear 22 to rotate in the opposite direction. The drive gear 22 drives the movable plate 23 to move in the opposite direction via the rack 24, causing the movable plate 23 to block the first air outlet 111. External air enters the cavity 113 through the air inlet 114 and then is blown out through the second air outlet 112, thus achieving air outlet 112.

[0036] In practical applications, in order to achieve better results, the number of both the first air outlet 111 and the second air outlet 112 can be set to multiple.

[0037] Preferably, there are two drive gears 22 and two racks 24. The two drive gears 22 are respectively sleeved on both ends of the rotating shaft 21, and the two racks 24 are respectively set on both ends of the movable plate 23. The two drive gears 22 mesh with the two racks 24 respectively. With this technical solution, compared with using one drive gear 22 and one rack 24, the torque can be transmitted to both ends of the movable plate 23 simultaneously through the rotating shaft 21 when the knob 31 is rotated, so that both ends of the movable plate 23 are subjected to force at the same time, ensuring that the movable plate 23 is subjected to force evenly. This ensures that the movable plate 23 can completely block the first air outlet 111 or the second air outlet 112 after it moves into place, avoiding the situation where insufficient blocking causes the first air outlet 111 and the second air outlet 112 to vent air at the same time.

[0038] Preferably, the movable plate 23 is provided with a guide limiting strip 233, and the inner side wall of the housing 11 of the hair dryer body 1 is provided with a guide limiting groove 15. The guide limiting strip 233 is located in the guide limiting groove 15 and can move within the guide limiting groove 15. When the movable plate 23 moves, the guide limiting strip 233 cooperates with the guide limiting groove 15 to ensure the moving accuracy of the movable plate 23. In addition, when the movable plate 23 moves into position, the end of the guide limiting strip 233 will abut against the end side wall of the guide limiting groove 15. At this time, the knob 31 can no longer be rotated to indicate to the consumer that the movable plate has moved into position.

[0039] Specifically, the guide limit strip 233 is disposed on the side of the movable plate 23 away from the drive gear 22, and the guide limit groove 15 is formed on the inner side wall of the housing 11.

[0040] Specifically, there are two guide limit bars 233 and two guide limit grooves 15. The two guide limit bars 233 are respectively set at both ends on the side of the movable plate 23 away from the drive gear 22, and the two guide limit grooves 15 are respectively opened at the corresponding positions on the inner side wall of the housing 11 and the side of the movable plate 23 away from the drive gear 22.

[0041] Preferably, both the first air outlet 111 and the second air outlet 112 include multiple through holes 1111, which are arranged in a straight line at intervals. This technical solution helps to distribute the airflow more evenly, reduce turbulence, and thus make the blown air more stable, thereby improving the hair drying efficiency.

[0042] Preferably, the side wall of the housing 11 of the hair dryer body 1 has a flat portion 115, and both the first air outlet 111 and the second air outlet 112 are formed on the flat portion 115, with the first air outlet 111 being perpendicular to the flat portion 115. By providing the flat portion 115 on the side wall of the hair dryer body 1 and having both the first air outlet 111 and the second air outlet 112 formed on the flat portion 115, the movable plate 23 can be designed as a simple flat plate structure, which is convenient for processing and production.

[0043] Preferably, the fan motor 12 in the cavity 113 is positioned near the air inlet 114, and the heating element 14 is positioned near the first air outlet 111 and the second air outlet 112; the control circuit board 13 is positioned between the fan motor 12 and the heating element 14. This technical solution allows cool air from the outside to be blown onto the control circuit board 13 by the fan motor 12, cooling the control circuit board 13 and preventing excessive heat generated during operation from affecting the performance of the hair styling tool.

[0044] Example 2

[0045] The difference between this embodiment and Embodiment 1 is that the movable plate 23 in this embodiment is provided with a first opening 231 and a second opening 232. The first opening 231 corresponds to the first air outlet 111. The second opening 232 corresponds to the second air outlet 112. In practical applications, if the first air outlet 111 is selected to discharge air, the switching mechanism is in the first state (as shown in Figure 4). At this time, the first opening 231 is connected to the first air outlet 111, and the second opening 232 is misaligned with the second air outlet 112 (i.e., the second opening 232 and the second air outlet 112 are not connected). External air enters the cavity 113 through the air inlet 114 and is then blown out through the first opening 231 from the first air outlet 111. If the second air outlet 112 is selected to discharge air, the switching mechanism is in the second state (as shown in Figure 5). At this time, the second opening 232 is connected to the second air outlet 112, and the first opening 231 is misaligned with the first air outlet 111 (i.e., the first opening 231 and the first air outlet 111 are not connected). External air enters the cavity 113 sequentially through the air inlet 114 and is then blown out through the second opening 232 from the second air outlet 112. With this technical solution, compared to not having the first opening 231 and the second opening 232 on the movable plate 23, the travel distance of the movable plate 23 is shortened when switching back and forth between the first air outlet 111 and the second air outlet 112, thereby reducing the switching time and effectively improving the switching efficiency.

[0046] Example 3

[0047] The difference between this embodiment and Embodiment 1 is that in this embodiment, the driving component 3 includes a push rod, and the movable component 2 includes a movable plate 23. The movable plate 23 is movably disposed inside the blower body 1 and connected to the push rod. The movable plate 23 can block the first air outlet 111 or the second air outlet 112 under the push of the push rod.

[0048] In practical applications, if the first air outlet 111 is selected for airflow, the push rod is pushed, causing the push rod to move the movable plate 23 to block the second air outlet 112, thus allowing air to flow from the first air outlet 111. If the second air outlet 112 is selected for airflow, the push rod is pushed in the opposite direction, causing the push rod to move the movable plate 23 to block the first air outlet 111, thus allowing air to flow from the second air outlet 112.

[0049] Example 4

[0050] The difference between this embodiment and Embodiment 3 is that the movable plate 23 in this embodiment is provided with a first opening 231 and a second opening 232. The first opening 231 corresponds to the first air outlet 111. The second opening 232 corresponds to the second air outlet 112. In practical applications, if the first air outlet 111 is selected to discharge air, the switching mechanism is in the first state. At this time, the first opening 231 is connected to the first air outlet 111, and the second opening 232 is misaligned with the second air outlet 112 (i.e., the second opening 232 and the second air outlet 112 are not connected). External air enters the cavity 113 sequentially through the air inlet 114, and then is blown out through the first opening 231 and the first air outlet 111. If the second air outlet 112 is selected to discharge air, the switching mechanism is in the second state. At this time, the second opening 232 is connected to the second air outlet 112, and the first opening 231 is misaligned with the first air outlet 111 (i.e., the first opening 231 and the first air outlet 111 are not connected). External air enters the cavity 113 sequentially through the air inlet 114, and then is blown out through the second opening 232 and the second air outlet 112. With this technical solution, compared to not having the first opening 231 and the second opening 232 on the movable plate 23, the travel distance of the movable plate 23 is shortened when switching back and forth between the first air outlet 111 and the second air outlet 112, thereby reducing the switching time and effectively improving the switching efficiency.

[0051] Example 5

[0052] The difference between this embodiment and Embodiment 1 is that in this embodiment, the driving component 3 includes a knob 31, and the movable component 2 includes a rotating shaft 21 and a movable plate 23. The movable plate 23 is connected to the rotating shaft 21, and the movable plate 23 can block the first air outlet 111 or the second air outlet 112 under the drive of the knob 31 and the rotating shaft 21.

[0053] In practical application, if the first air outlet 111 is selected for airflow, rotating the knob 31 in the forward direction will cause the rotating shaft 21 to rotate, which in turn will cause the movable plate 23 to rotate, thus blocking the second air outlet 112 and allowing air to flow from the first air outlet 111. If the second air outlet 112 is selected for airflow, rotating the knob 31 in the reverse direction will cause the rotating shaft 21 to rotate in the reverse direction, thus blocking the first air outlet 111 and allowing air to flow from the second air outlet 112.

[0054] Example 6

[0055] As shown in Figure 6, the difference between this embodiment and Embodiment 2 is that the side wall of the housing 11 in this embodiment also has a third air outlet 116. The third air outlet 116 is located on the side of the first air outlet 111 away from the second air outlet 112. The third air outlet 116 and the first air outlet 111 form an angle β, where 0° < β ≤ 90°, and the third air outlet 116 and the second air outlet 112 form an angle γ, where 0° < γ ≤ 180°. In specific applications, the movable plate 23 of the movable component 2 can simultaneously block the first air outlet 111 and the second air outlet 112, or simultaneously block the first air outlet 111 and the third air outlet 116, or simultaneously block the second air outlet 112 and the third air outlet 116, under the drive of the driving component 3.

[0056] In practical application, the movable plate 23 has a third opening that corresponds to the third air outlet 116. When the movable plate 23 blocks the first air outlet 111 and the second air outlet 112, the first opening 231 is misaligned with the first air outlet 111, the second opening 232 is misaligned with the second air outlet 112, and the third opening corresponds to the third air outlet 116, from which air is blown out; when the movable plate 23 blocks the first air outlet 111 and the third air outlet 116 ... third air outlet 116, the second opening 232 is misaligned with the third air outlet 116, the third opening 231 is misaligned with the third air outlet 116, the third opening 232 is misaligned with the third air outlet 116, the third opening 231 is misaligned with the third air outlet 116, the third opening 232 is misaligned with the third air outlet 116, the third opening 231 is misaligned with the third air outlet 116, the third opening 232 is misaligned with the third air outlet 116, the third opening 231 is misaligned with the third air outlet 116, the third opening 232 is misaligned with the third air outlet 116, the third opening 231 is misaligned with the third air outlet 116, the third opening 232 is misaligned with the third air outlet 116, the third opening 232 is misaligned with the third air outlet 116, the third opening The second opening 232 is offset from the first air outlet 111, the third opening is offset from the third air outlet 116, and the second opening 232 corresponds to the second air outlet 112, with air blowing out from the second air outlet 112; when the movable plate 23 blocks the second air outlet 112 and the third air outlet 116, the second opening 232 is offset from the second air outlet 112, the third opening is offset from the third air outlet 116, the first opening 231 corresponds to the first air outlet 111, and air blows out from the first air outlet 111.

[0057] In practical applications, since everyone has a different dominant hand, some people are right-handed and some are left-handed. Taking the right hand holding the hair dryer body 1 as an example, when the second air outlet 112 is selected to emit air, and the second air outlet 112 is tilted downward, if the left hand holds the hair dryer body 1, the second air outlet 112 tilted downward will become tilted upward. At this time, the moving plate 23 can be moved by the driving component 3, so that the moving plate 23 simultaneously blocks the first air outlet 111 and the second air outlet 112, so that the air blows out from the third air outlet 116, so that there is no difference in the user experience when using the hair dryer body 1 with the left hand and the right hand.

[0058] In summary, in one or more embodiments of the present invention, the hair styling tool of the present invention provides an active component 2 connected to the driving component 3 inside the hair dryer body 1, so that the active component 2 can block the first air outlet 111 or the second air outlet 112 under the drive of the driving component 3, thereby changing the airflow direction of the hair dryer to meet different user needs.

[0059] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
