[0035] The air comb accessory also includes an air outlet control mechanism 70, configured to control the opening and closing of the first movable door 50 and the second movable door 60; the air outlet control mechanism 70 has a first operating state and a second operating state; wherein, in the first operating state, the first movable door 50 is axially open and the second movable door 60 is closed; in the second operating state, the second movable door 60 is circumferentially open and the first movable door 50 is closed.

[0036] Both ends of the second movable door 60 are rotatably connected to the outer casing 10 via a rotating shaft a1 parallel to the axis of the outer casing 10.

[0037] The comb accessory of this solution has a compact overall structure and is easy to use. In the first operating state, the first movable door 50 is axially opened and the second movable door 60 is opened via the air outlet control mechanism 70, at which time airflow can be blown out from the first air outlet 30. In the second operating state, the second movable door 60 is circumferentially opened and the first movable door 50 is closed, at which time airflow can be blown out from the second air outlet 40. Two air outlet modes are available for users to choose from, which greatly improves the user experience and meets the needs of choosing the air outlet direction.

[0038] In this embodiment, the side wall of the outer casing 10 is also provided with a third air outlet 80 and a third movable door 90 for opening or closing the third air outlet 80. The first movable door 50, the second movable door 60 and the third movable door 90 are evenly arranged on the outer peripheral side wall of the barrel 11. Furthermore, the air outlet control mechanism 70 also has a third operating state. In the third operating state, the third movable door 90 is circumferentially open and the second movable door 60 and the first movable door 50 are both closed. By further adding the third air outlet 80, more usage requirements of users for the air outlet direction can be further met. The third movable door 90 is also rotatably connected to the outer casing through another pivot a2.

[0039] In practice, the first air outlet 30 is in the normally open state. At this time, the air outlet control mechanism 70 is in the initial state, and the second air outlet 40 and the third air outlet 80 are both in the closed state. When the user needs to select the first air outlet 30 or the second air outlet 40 to emit air, he can operate the air outlet control mechanism 70 to make the corresponding action. Generally, the second operation state is left rotation, and the third operation state is right rotation.

[0040] In this embodiment, an installation window 101 is provided on the outer shell 10 at the position corresponding to the first movable door 50. A sealing plate 100 is provided on the outer shell 10 to seal the installation window 101. The first movable door 50 is axially slidably connected to the outer shell 10 and slidably fits against the inner side wall of the sealing plate 100. The first air outlet 30 is provided on the sealing plate 100, and the first movable door 50 is provided with a through hole 501. In the open state, the first air outlet 30 and the through hole 501 are radially opposite and completely overlap to form a channel for airflow. In the closed state, the first air outlet 30 and the through hole 501 are completely misaligned and can be blocked by the sealing plate 100.

[0041] In this embodiment, the sealing plate 100 is detachably connected to the outer casing 10 to facilitate disassembly and installation.

[0042] In this embodiment, the first air outlet 30 is elongated and arranged along the circumferential direction of the outer shell 10. Multiple first air outlets 30 and through holes 501 are provided and are evenly arranged along the axial direction of the outer shell 10. In the closed state, the first air outlet 30 and the through holes 501 are axially staggered to ensure that the first air outlet 30 is in a closed state, thus ensuring the air volume of the second air outlet 40 or the third air outlet 80.

[0043] In this embodiment, the first movable door 50 is located on the inward side of the sealing plate 100, so as to guide and limit the axial sliding of the first movable door 50 by the sealing plate 100, preventing the first movable door 50 from radially separating from the outer shell 10; furthermore, a partition 110 is provided on the inward side wall of the first movable door 50 between each pair of adjacent through holes 501, and the multiple partitions 110 are arranged circumferentially along the outer shell 10, and the radial ends of the multiple partitions 110 are closed, so that the first movable door 50... The inner space of the inner wall forms an air intake chamber 120 for each through hole 501. Furthermore, the radial length of multiple baffles 110 increases sequentially in the direction away from the air inlet 20. That is, each baffle 110 is perpendicular to the axis of the outer shell 10. Specifically, the end faces of the multiple baffles 110 are distributed in a stepped manner. This layout design allows the airflow entering through the air inlet 20 to be evenly distributed into each first air outlet, avoiding excessive differences in airflow between the far end and the near end, thus ensuring uniform airflow.

[0044] In this embodiment, comb teeth 130 are provided on the side wall of the sealing plate 100 facing outward. Multiple comb teeth 130 are provided and are evenly distributed in a matrix on the sealing plate 100. A row of comb teeth 130 is arranged side by side on both sides of the axial direction of each air outlet. The comb teeth 130 are detachably connected to the sealing plate 100. This structural design can meet the user's needs for drying hair while combing.

[0045] In this embodiment, the air outlet control mechanism 70 is located on one end face of the outer shell 10 away from the air inlet 20; further, the outer shell 10 also includes a mask 13 covering the air outlet control mechanism 70 on the end face of the outer shell 10, and the mask 13 is detachably connected to the barrel body 11.

[0046] Furthermore, the air outlet control mechanism 70 includes a turntable 71 rotatably connected to the housing 10 on the same axis, and a hand-tightening knob 72 fixed on the same axis as the turntable 71. The axis of the housing 10 is the axis of the turntable 71. The hand-tightening knob 72 is connected to the turntable 71 via a fixed shaft 140, which passes through the turntable 71 and is rotatably connected to the housing on the same axis. When installed in place, the hand-tightening knob 72 is located on the outside of the face mask 13, and the fixed shaft 140 passes through the face mask 13 and is connected to the hand-tightening knob 72, so as to facilitate operation and also to enhance the appearance.

[0047] Furthermore, both the second movable door 60 and the third movable door 90 are provided with swing arms 150 arranged axially parallel to the turntable 71. That is, the swing arms 150 are installed in the radial direction of the outer casing 10 with the second movable door 60 and the third movable door 90 respectively. Specifically, the swing arms 150 on the second movable door 60 and the third movable door 90 are located in the middle of their corresponding air outlet ends. Moreover, the swing arm 150 on the second movable door 60 is located on the side of the second movable door 60 with the pivot a1 facing the opening end of the second movable door 60 and the angle between it and the opening end of the second movable door 60 is an acute angle. Similarly, the swing arm 150 on the third movable door 90 also adopts the same installation method.

[0048] Furthermore, a first convex shaft 160 is axially provided on the end of one side wall of the swing arm 150 facing the turntable 71, and two first push grooves 170 are provided on the turntable 71. One of the first push grooves 170 is used to cooperate with the first convex shaft 160 and the swing arm 150 to push the third movable door 90 to open and close when they rotate. Specifically, the opening and closing process of the third movable door 90 is as follows: If the third movable door 90 is initially closed, and it needs to be opened, the turntable 71 is rotated and the first push groove 170 corresponding to the third movable door 90 pushes the first convex shaft 160 inside it in the direction of rotation during the rotation. The third movable door 90 can be pushed open in the direction of rotation by the support and transmission of the corresponding swing arm 150. If the third movable door 90 needs to be closed, the turntable 71 is rotated in the opposite direction.

[0049] Furthermore, another first push slide 170 of the two first push slides 170 is used to cooperate with the corresponding first push slide 170 that pushes the second movable door 60 to open and close when the first convex shaft 160 and the swing arm 150 are both rotated; specifically, the opening and closing process of the second movable door 60 is as follows: If the second movable door 60 is initially closed, and it needs to be opened, the turntable 71 is rotated and the first push groove 170 corresponding to the second movable door 60 pushes the first convex shaft 160 inside it in the direction of rotation during the rotation. The second movable door 60 can be opened by the support and transmission of the corresponding swing arm 150. If the second movable door 60 needs to be closed, the turntable 71 is rotated in the opposite direction.

[0050] The width of the first push groove 170 is adapted to the diameter of the first convex shaft 160, and the first convex shaft 160 can move within the first push groove 170 during the rotation of the turntable 71.

[0051] Furthermore, the turntable 71 is provided with a radial second convex shaft 180 on its peripheral sidewall, and the first movable door 50 is provided with a second push groove 181 on its inward sidewall, which cooperates with the second convex shaft to push the first movable door 50 to open and close when rotating. In the initial state, the first movable door 50 is open. To close the first movable door 50, the turntable 71 is rotated in conjunction with the second push groove 181 to push the second convex shaft 180 axially, thereby causing the first movable door 50 to move axially and causing the first air outlet 30 and the through hole 501 to be misaligned, thereby closing the first air outlet 30.

[0052] Specifically, the two first push grooves 170 are symmetrically distributed in a V-shape on the turntable 71, with the axis of the turntable 71 located in the middle of the first push grooves 170. The rotating shaft a1 is located on the side of the second / third movable door 90 closer to the first movable door. The second convex shaft 180 is located on the side with the larger distance between the two first push grooves 170 and is located on the symmetrical plane of the first push grooves 170. This design allows the second movable door 60 to be opened or closed when the turntable 71 is rotated to the left (while the first movable door 50 and the third movable door 90 are closed), and to be rotated to the right... When the turntable 71 is closed, the third movable door 90 can be opened or closed (while the first movable door 50 and the second movable door 60 are closed); furthermore, the first push slide 170 is elongated, and the end with the larger distance between the two first push slides 170 is an arc with the same curvature as the turntable 71, while the distance between the end with the smaller distance and the axis of the turntable 71 gradually increases along the length direction away from the end with the larger distance; when both the second movable door 60 and the third movable door 90 are closed, the two second convex shafts 180 are located in the middle of the two first push slides 170 respectively.

[0053] Specifically, when the left rotating disk 71 is turned, the first convex shaft 160 on the left enters the rear end of the rotation direction of the first push slide 170, and the distance between the first convex shaft 160 and the axis of the rotating disk 71 increases, thereby pushing and rotating the second or third movable door 60 to open it; at the same time, the first convex shaft 160 on the right enters the rear end of the rotation direction of the first push slide 170 on the right, keeping the distance between the first convex shaft 160 on the right and the center of the rotating disk 71 unchanged, thereby keeping the third movable door 90 on the right closed; when the right rotating disk 71 is turned, the actions of the first movable door 50 and the third movable door 90 are opposite, that is, the third movable door 90 opens, and the second movable door 60 remains closed.

[0054] Furthermore, the second push slide 181 is V-shaped, and its two arms have an arc transition section 182 at the bend, with the tip facing the air inlet 20. In the initial state, the second convex shaft 180 is located in the middle of the arc transition section 182 of the second push slide 181, keeping the first movable door 50 in the open state. When the left rotating disk 71 is turned, the left first convex shaft 160 enters the rear end of the rotation direction of the first push slide 170, and the distance between the first convex shaft 160 and the axis of the rotating disk 71 increases, thereby pushing and rotating the second or movable door 50 to open it. At the same time, the right first convex shaft 160 enters the rear end of the rotation direction of the right first push slide 170, keeping the right first convex shaft 160 and the rotating disk 71 in the same direction. The center distance remains unchanged, thus keeping the third movable door 90 on the right side closed; at the same time, the second convex shaft 180 enters the left support arm of the second push slide 181 and pushes along its front wall, at which point the first movable door 50 can be pushed forward axially and slid, so that the first air outlet 30 is misaligned with the through hole 501 and closed; when the right rotating disk 71 opens the third movable door 90 on the right side, the first movable door 50 and the third movable door 90 move in opposite directions, and the second convex shaft 180 first returns to the arc transition section 182 and continues to enter the right support arm of the second push slide 181, that is, the third movable door 90 opens, while the first movable door 50 and the second movable door 60 remain closed.

[0055] In this embodiment, a radial positioning pin 190 is provided on the outer peripheral sidewall of the turntable 71, and the positioning pin 190 is collinear with the second convex shaft 180; a concentric arc-shaped dam 200 is provided on the outer shell 10 along the rotation trajectory of the end of the positioning pin 190, and positioning grooves 201 for the positioning pin 190 to abut at both ends and the middle of the concave sidewall of the arc-shaped dam 200; specifically, When the first movable gate 50 is opened, the positioning pin 190 rotates and engages in the positioning groove 201 in the middle of the arc-shaped cofferdam 200; When the second movable door 60 is opened, the positioning pin 190 rotates and engages in the positioning groove 201 at the end of the arc-shaped cofferdam 200 corresponding to the second movable door 60; When the third movable gate 90 is opened, the positioning pin 190 rotates and engages with the positioning groove 201 at the other end of the arc-shaped cofferdam 200 corresponding to the third movable gate 90.

[0056] The cooperation of the positioning pin and the three positioning slots 201 produces a pleasant clicking sound when the rotating dial is in position, serving as a reminder to the user that the adjustment is complete and enhancing the user experience. It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
