[0021] The technical solution of the present invention has the following advantages:

[0022] 1. The air outlet device provided by the present invention comprises: a casing, with a fan blade and a first power member connected to the fan blade built in, a first air outlet and a second air outlet on the casing, the first air outlet being arranged along the circumference of the casing, the second air outlet being arranged at an end of the casing in the air outlet direction of the fan blade, a switch member being arranged at a position adjacent to the second air outlet, the switch member being suitable for controlling the opening and closing of the second air outlet; a direction adjustment device being connected to the casing and suitable for adjusting the casing so that the casing has a first air outlet position in which the first air outlet is arranged horizontally and circumferentially, and a second air outlet position in which the second air outlet is arranged laterally.

[0023] The casing is equipped with fan blades and a first power component, which can discharge air along the outlet direction. By respectively setting a first air outlet for circumferential air discharge and a second air outlet for straight air discharge, the casing can be turned by a direction adjustment device, and then the first air outlet can be selectively adjusted to be horizontal or the second air outlet can be selectively adjusted to be lateral, so that each air outlet can be aimed at the user to discharge air, thereby realizing a conversion in the form of air outlet.

[0024] 2. The air outlet device provided by the present invention, the direction adjustment device also includes a stop part, which is suitable for controlling the start and stop of the slide rail assembly relative to the sliding block, including: a plurality of stop holes, which are arranged on the slide rail assembly, arranged linearly and distributed along the extension direction of the slide rail assembly; a clamping part, which is provided on the sliding block, including an elastic part and a clamping part, and under the action of the elastic part, the clamping part has a stop state of extending into the stop hole, and a running state of disengaging from the stop hole.

[0025] By cooperating with the stop hole and the clamping part, effective control of the relative fixation or relative movement between the slide rail assembly and the slider part is achieved. At the same time, the coordination and fixation of the hole part and the shaft part is more stable than other fixing forms, such as rack and tooth block positioning or clamping block and slot positioning.

[0050] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] like Figure 1 - Figure 14 This embodiment provides an air outlet device, specifically a fan, which can also be an air cooler, a hair dryer, etc., which includes: a casing 1 and a direction adjustment device 5.

[0052] The housing 1 is barrel-shaped, with an arc-shaped sidewall, and is equipped with a fan blade 2, a first power member 3, and a switch member 4. A first air outlet 11, a second air outlet 12, and an air inlet 13 are provided on the housing 1. The second air outlet 12 and the air inlet 13 are respectively provided at the two ends of the housing 1, and the first air outlet 11 is provided in the middle along the circumferential direction. In this embodiment, grilles or filters are provided on the first air outlet 11, the second air outlet 12, and the air inlet 13 to prevent large particles of debris from entering the housing 1 and to prevent people from accidentally touching the fan blade 2 on the inner wall, which may cause danger. Furthermore, the switch member 4 is provided adjacent to the second air outlet 12 to control the opening and closing of the second air outlet 12. The fan blade 2 is connected to the first power member 3, and its air outlet direction is from the air inlet 13 to the second air outlet 12.

[0053] The direction adjustment device 5 is partially connected to the casing 1, and can adjust the direction of the casing 1 so that the casing 1 has a first air outlet position in which the first air outlet 11 is horizontally arranged in a circumferential direction, the air inlet 13 is at the bottom, and the second air outlet 12 is at the top, and a second air outlet position in which the second air outlet 12 and the air inlet 13 are both arranged laterally. In this embodiment, the lateral direction refers to the horizontal direction or the oblique direction with an acute angle to the horizontal direction.

[0054] The casing 1 is equipped with fan blades 2 and a first power part 3, which can discharge air along the outlet direction. By respectively setting a first air outlet 11 for circumferential air outlet and a second air outlet 12 for straight air outlet, the casing 1 can be turned by the adjusting device 5, and then the first air outlet 11 can be selectively adjusted to be horizontal or the second air outlet 12 can be adjusted to be lateral, so that each air outlet can be aimed at the user to discharge air, thereby realizing a conversion in the form of air outlet. This setting can not only concentrate wind force to discharge air in one direction, but also close the second air outlet 12 through the switch part 4, so that the air flow is blown out from the first air outlet 11 along the horizontal circumferential direction, so that users at different positions can be exposed to the wind at the same time, effectively expanding the air outlet range of the fan, and overcoming the defect that the fan with the adjusting device 5 in the prior art cannot realize simultaneous circumferential air supply.

[0055] The direction adjustment device 5 includes a slide rail assembly 51 and a slider 52. In this embodiment, the slide rail assembly 51 is arranged on the housing 1; the slider 52 is arranged on the slide rail assembly 51, and can move relative to the slide rail assembly 51 under the action of an external force, and adjust the housing 1 to move between the first air outlet position and the second air outlet position. The external force can be a manual driving force, or an external force such as a motor can be provided. As a convertible embodiment, the slider 52 can be arranged on the housing 1, and the slide rail assembly 51 is spaced from the housing 1 and moves relative to the slider 52. In this embodiment, the first power member 3 and the power part 421 are both motors.

[0056] The air outlet device further includes a bottom shell 6 adapted to receive the housing 1, a slide rail assembly 51 connected to the housing 1, and a slider 52 connecting the bottom shell 6 and the slide rail assembly 51. As an alternative embodiment, the bottom shell 6 may be omitted, and the housing 1 and the slide rail assembly 51 may be supported by the slider 52.

[0057] The slide rail assembly 51 includes a first slide rail 511 and a second slide rail 512. The first slide rail 511 is arranged at one end of the casing 1 facing away from the second air outlet 12; the second slide rail 512 and the first slide rail 511 are arranged on the same track and are fixedly connected. The second slide rail 512 and the sliding block 52 move relative to each other. The second slide rail 512 is provided with a rail groove 513 and a stop portion. The rail groove 513 is arranged on the same track as the first slide rail 511 and the second slide rail 512, and can accommodate and limit the sliding block 52.

[0058] In this embodiment, the air inlet 13 is disposed at the end of the housing 1 facing away from the second air outlet 12, and the slide rail assembly 51 is disposed in an arc shape on the outer edge of the air inlet 13. This arrangement allows the air inlet 13 to be disposed inside the arc-shaped slide rail assembly 51 and spaced apart from the slide rail assembly 51, preventing the slide rail assembly 51 from blocking the air inlet 13 and improving the air intake effect of the air inlet 13.

[0059] The slider member 52 includes a slider body 521 and a rolling assembly.

[0060] The slider body 521 is limitedly set on the track groove 513, and an inner groove is set in the middle, which can be movably connected to the second slide rail 512. A receiving groove 523 is set on the side facing the first slide rail 511 to accommodate part of the rolling component.

[0061] The rolling assembly is connected to the receiving groove 523 and includes a first roller 524, a first shaft 527, a second roller 525, and a second shaft 528. The first shaft 527 passes through the first roller 524 and is fixed at both ends to the edges of the receiving groove 523. The first roller 524 is movably disposed within the receiving groove 523, contacting and rotating relative to the first slide rail 511. The second shaft 528 passes through the edge of the receiving groove 523. The second roller 525 is mounted on the second shaft 528 outside the receiving groove 523, contacting and rotating relative to the second slide rail 512.

[0062] The steering device 5 also includes a stop part, which can control the start and stop of the slide rail assembly 51 relative to the slider 52. The stop part includes a plurality of stop holes 514 arranged on the second slide rail 512, and the plurality of stop holes 514 are arranged in an arc shape with the same trajectory as the second slide rail 512 and evenly spaced; the clamping part 526 is arranged in the accommodating cavity of the accommodating groove 523, and an elastic part and a columnar clamping part are provided in the cavity, and a first clamping structure with an annular protrusion is provided on the clamping part. Under the action of the elastic part, it can pop out of the accommodating cavity and extend into the stop hole 514 to be in a stopped state. It can also be retracted into the accommodating groove 523 under the action of external force such as manual or electric push rod and engaged with the first clamping structure in the shape of a barb in the accommodating cavity to limit the operating state.

[0063] Furthermore, a single first air outlet 11 is arranged in a ring shape on the housing 1, with side grilles provided thereon for discharging air and connecting the two parts of the housing 1. This arrangement increases the air outlet range of the first air outlet 11. As an alternative embodiment, multiple first air outlets 11 can be arranged in a spaced-apart ring shape on the housing 1.

[0064] The switch 4 includes an air grille 41 and a second power element 42. The air grille 41 is positioned between the first air outlet 11 and the second air outlet 12. The second power element 42 is connected to the air grille 41. Under the action of the second power element 42, the air grille 41 can have two positions: a wind-blocking position perpendicular to the airflow direction, and a wind-discharging position parallel to the airflow direction. As an alternative embodiment, the switch 4 can also be configured without the second power element 42. Instead, the air grille 41 can be positioned above the second air outlet 12, with the two positions switched manually.

[0065] The air outlet grille 41 specifically includes a plurality of wind shields 411, which are evenly arranged in the shape of fan rings and arranged along a ring, including a bent lever structure 412 extending toward the center of the ring. The lever structure 412 is connected to the second power member 42 and is suitable for driving the wind shield 411 to rotate under the action of the second power member 42.

[0066] The wind shield 411 arranged in a ring can be combined with the second power part 42 set in the middle to be set in a circle, which can block the air outlet from the first power part 3 and the fan blade 2, ensuring the sealing effect of the second air outlet 12. At the same time, since the wind shield 411 is set between the first air outlet 11 and the second air outlet 12, the wind shield 411 can guide the airflow to the first air outlet 11 when it is in the wind-blocking state, thereby realizing circumferential air outlet.

[0067] In this embodiment, the second power member 42 includes a power unit 421, a first gear unit 422, a second gear unit 423, and a support unit 424. The output shaft of the power unit 421 passes through the umbrella-shaped support unit 424. The first gear unit 422 is connected to the output shaft of the power unit 421 and is disposed on both sides of the support unit 424 along with the main body of the power unit 421. The second gear unit 423 includes an inner tooth portion and an outer tooth portion, with a through hole in the middle portion to accommodate the handle of the support unit 424 and rotate relative thereto. The inner tooth portion meshes with the first gear unit 422, and the outer tooth portion engages with each of the shifting lever structures 412.

[0068] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description.
