The air outlet device is often required to meet the blowing requirements of different heights in different use scenes, such as the use scenes of different heights, such as the ground or a table top. Based on this, air-out device need adjust between the not co-altitude to can stably lock in the not co-altitude, just can realize blowing in the stability of not co-altitude.

At present, the locking mode that air-out device adopted when height-adjusting mainly has following two kinds, and one of them adopts the spring to bump the pearl structure and realizes air-out device's locking. This kind of locking mode is simple easy to operate, but the spring bumps the pearl structure and can't avoid the air-out device to cause to drop in the influence of exogenic action to along with long-term the use, the spring bumps the pearl structure and takes place wearing and tearing easily and became invalid, leads to the locking reliability of air-out device to be low. And secondly, locking is carried out by adopting a manual locking mode. Although the reliability of the mode is higher, the structure and the operation are very complicated, so that the use experience of the air outlet device is poor.

Based on the consideration, the applicant provides an air outlet device through deep research, can realize the locking of air outlet device at specific height through controlling the handpiece subassembly, simple structure and be convenient for operate, experience when effectively improving the air outlet device and using is felt.

Referring to fig. 1 and fig. 2, an embodiment of the present application provides an air outlet device 100, which includes a chassis assembly 10, a head assembly 20, and an adjusting assembly 30, wherein the chassis assembly 10 is provided with a first matching portion 11, and the head assembly 20 is provided with a second matching portion 21. The adjustment assembly 30 is movably coupled between the base assembly 10 and the head assembly 20 to adjust a distance therebetween in a predetermined direction a. The adjusting component 30 is provided with a first limiting portion 31 and a second limiting portion 32 connected to the second matching portion 21, and the adjusting component 30 has a first position and a second position in the predetermined direction a.

When the adjusting assembly 30 is located at the first position, the first position-limiting portion 31 is connected to the first engaging portion 11, and the second position-limiting portion 32 is stationary relative to the second engaging portion 21. When the adjusting assembly 30 is located at the second position, the first limiting portion 31 is separated from the first engaging portion 11, and the second engaging portion 21 can drive the first limiting portion 31 to move, so that the adjusting assembly 30 is locked at the second position.

It should be noted that the chassis assembly 10 refers to a base of the air outlet device 100, and provides a mounting and supporting base for the structures such as the head assembly 20 and the adjusting assembly 30. The head assembly 20 is an actual blowing structure of the air-out device 100, and therefore, the distance between the head assembly 20 and the chassis assembly 10 is adjusted along the preset direction a by the adjusting assembly 30, that is, the blowing height of the air-out device 100 is adjusted. Specifically, the larger the distance between the head assembly 20 and the chassis assembly 10 is, the higher the blowing height of the air-out device 100 is, and conversely, the smaller the distance between the head assembly 20 and the chassis assembly 10 is, the lower the blowing height of the air-out device 100 is.

The adjusting assembly 30 is mutually matched with the first matching part 11 on the chassis assembly 10 through the first limiting part 31, so that the connection between the adjusting assembly 30 and the chassis assembly 10 is realized. The adjusting assembly 30 is mutually matched with the second matching part 21 on the head assembly 20 through the second limiting part 32, so that the connection between the adjusting assembly 30 and the head assembly 20 is realized.

When the adjusting assembly 30 adjusts the distance between the base assembly 10 and the head assembly 20, the adjusting assembly 30 moves along the preset direction a, and has a first position and a second position during the movement. Therefore, when the adjusting assembly 30 is located at the first position, the distance between the head assembly 20 and the chassis assembly 10 is different from that when the adjusting assembly 30 is located at the second position, that is, the process of switching the adjusting assembly 30 between the first position and the second position is actually the process of adjusting the distance between the head assembly 20 and the chassis assembly 10, that is, the process of adjusting the blowing height of the air outlet device 100.

Specifically, when the adjusting assembly 30 is located at the first position, the first limiting portion 31 is connected with the first matching portion 11 in a matching manner, so that the adjusting assembly 30 moves along the preset direction a, and at this time, the second limiting portion 32 on the adjusting assembly 30 is stationary relative to the second matching portion 21 on the handpiece assembly 20, so that the adjusting assembly 30 can move smoothly in the preset direction a.

When the adjusting assembly 30 moves from the first position to the second position, the first position-limiting portion 31 and the first engaging portion 11 are separated from each other, so that the second engaging portion 21 can drive the first position-limiting portion 31 to move. In the process that the second matching portion 21 drives the first limiting portion 31 to move, the head assembly 20 actually drives the adjusting assembly 30 to move, so that the adjusting assembly 30 can be locked at the second position by controlling the head assembly 20, that is, the head assembly 20 is locked at the height position of the adjusting assembly 30 at the second position.

It should be noted that the first position is not limited to a fixed position, but may include a plurality of sub-positions arranged along the preset direction a. When the adjusting assembly 30 is located at any one of the first positions, the first position-limiting portion 31 is connected to the first engaging portion 11, and the second position-limiting portion 32 is in a relatively stationary state with respect to the second engaging portion 21.

The process of adjusting the movement of the assembly 30 between the sub-positions in the first position is also the process of adjusting the distance between the head assembly 20 and the chassis assembly 10. When the adjusting assembly 30 moves from a certain sub-position to the second position, the first limiting portion 31 is separated from the first engaging portion 11, and at this time, the second engaging portion 21 on the head assembly 20 can drive the first limiting portion 31 to move, so as to drive the adjusting assembly 30 to move synchronously, and lock the adjusting assembly 30 at the second position.

Through the structure, after the distance between the machine head assembly 20 and the chassis assembly 10 is adjusted, the machine head assembly 20 can be locked at the height of the second position of the adjusting assembly 30 through the control machine head assembly 20, so that the height adjustment of the air outlet device 100 can be conveniently and quickly realized, and the operation is simple.

Referring to fig. 1 and fig. 3 together, in some embodiments, the adjusting assembly 30 includes a rotating shaft 33, and the first limiting portion 31 is disposed on the rotating shaft 33 in a protruding manner along an axial direction of the rotating shaft 33. The first engaging portion 11 is configured as a sliding slot opened on the chassis assembly 10, and the rotating shaft 33 and the first limiting portion 31 can move in the sliding slot along the predetermined direction a.

It should be noted that, the sliding groove extends along the predetermined direction a, so that the rotating shaft 33 and the first limiting portion 31 can move along the predetermined direction a in the sliding groove.

Further, the axial direction of the rotation shaft 33 is parallel to the preset direction a. Thereby, the rotating shaft 33 can move in the sliding groove in a telescopic manner along the axial direction, so that the distance between the head assembly 20 and the chassis assembly 10 can be adjusted.

When the rotating shaft 33 moves in the sliding groove, the first limiting portion 31 can limit the rotating shaft 33 along the circumferential direction of the rotating shaft 33, so that the rotating shaft 33 is prevented from rotating along the circumferential direction, and the rotating shaft 33 can move more stably along the preset direction a.

Referring to fig. 4 and 5, in some embodiments, when the adjusting assembly 30 is located at the first position, the first position-limiting portion 31 is located in the sliding groove and limits the rotating shaft 33 along the circumferential direction thereof. When the adjusting assembly 30 is located at the second position, the first limiting portion 31 is separated from the sliding groove and can abut against the chassis assembly 10 along the predetermined direction a.

Specifically, the length of the first stopper portion 31 in the axial direction of the rotating shaft 33 is smaller than the length of the rotating shaft 33. When the adjusting assembly 30 is located at the first position, the rotating shaft 33 and the first limiting portion 31 are both located in the sliding slot, and the rotating shaft 33 and the first limiting portion 31 can move in the sliding slot along the axial direction. In addition, the first limiting portion 31 can limit the rotating shaft 33 along the axial direction of the rotating shaft 33, so that the rotating shaft 33 is prevented from rotating in the circumferential direction in the sliding groove, and the rotating shaft 33 is ensured to stably move in the sliding groove along the preset direction a.

When the adjusting assembly 30 is located at the second position, the rotating shaft 33 is still located in the sliding slot, and the first limiting portion 31 is separated from the sliding slot and located outside the sliding slot. At this moment, the rotating shaft 33 can rotate along the circumferential direction, and after the rotating shaft 33 rotates a certain angle, under the action of the gravity of the adjusting assembly 30 and the head assembly 20 connected with the adjusting assembly, the first limiting portion 31 can abut downwards on the chassis assembly 10, so that the adjusting assembly 30 is locked at the second position.

It should be noted that the first position-limiting portion 31 may be provided as a continuous structure extending along the axial direction of the rotating shaft 33, and the length of the first position-limiting portion 31 along the axial direction of the rotating shaft 33 is smaller than the length of the rotating shaft 33. Therefore, when the first position-limiting portion 31 is located in the sliding groove, the adjusting assembly 30 is located at the first position, and is limited by the first position-limiting portion 31 along the circumferential direction of the rotating shaft 33. As the rotating shaft 33 moves in the sliding slot along the predetermined direction a, when the first position-limiting portion 31 moves to the outside of the sliding slot, the adjusting assembly 30 moves from the first position to the second position, and at this time, the first position-limiting portion 31 releases the position limitation of the rotating shaft 33 along the circumferential direction thereof. When the rotating shaft 33 rotates a certain angle along the circumferential direction, the first limiting portion 31 and the sliding groove are staggered, and at this time, the first limiting portion 31 can abut against the floor assembly along the preset direction a, so that the adjusting assembly 30 is locked at the second position.

In addition, the first position-limiting portion 31 may also be disposed as a plurality of sub-position-limiting portions at intervals along the axial direction of the rotating shaft 33, each sub-position-limiting portion corresponds to one of the first positions of the adjusting assembly 30, and an interval between every two adjacent sub-position-limiting portions corresponds to one of the second positions of the adjusting assembly 30.

Therefore, the adjusting assembly 30 in the above structure includes a plurality of second positions, and the locking of the adjusting assembly 30 at the second positions of a plurality of different heights can be realized, so as to realize the locking of the air outlet device 100 at different heights.

Referring to fig. 6, in some embodiments, the sliding slot includes a first notch 111 engaged with the rotating shaft 33 and a second notch 112 engaged with the first limiting portion 31, and an inner contour of the first notch 111 matches a projection contour of the rotating shaft 33 in a plane perpendicular to an axial direction thereof, so that the rotating shaft 33 can be inserted into the first notch 111. And/or the inner contour of the second notch 112 matches the projection contour of the first stopper portion 31 in a plane perpendicular to the axial direction of the rotary shaft 33, so that the first stopper portion 31 can be inserted into the second notch 112.

Referring to fig. 7 and 8, specifically, the first notch 111 and the second notch 112 are communicated with each other and respectively correspond to the rotating shaft 33 and the first limiting portion 31. When the adjusting assembly 30 is located at the first position, the rotating shaft 33 is located in the first notch 111, and meanwhile, the first position-limiting portion 31 is located in the second notch 112. Thereby, the first stopper portion 31 may block the rotation shaft 33 from rotating in the circumferential direction within the first notch 111.

Referring to fig. 9 and 10, when the adjusting assembly 30 moves from the first position to the second position, the rotating shaft 33 is still located in the first notch 111, and the first position-limiting portion 31 is separated from the second notch 112. At this time, the rotation shaft 33 may rotate in the circumferential direction within the first notch 111.

The inner contour of the first slot 111 is configured to match the cross-sectional contour of the rotating shaft 33, so that the rotating shaft 33 can be more stably disposed in the first slot 111, and the rotating shaft 33 is prevented from being shifted in the first slot 111, so that the rotating shaft 33 can move in the first slot 111 along the preset direction a more stably.

The inner contour of the second notch 112 is configured to match the cross-sectional contour of the first position-limiting portion 31, so that the first position-limiting portion 31 can be better accommodated in the second notch 112. In addition, when the first limiting portion 31 is separated from the second notch 112, the first limiting portion 31 and the second notch 112 can be staggered along the axial direction of the rotating shaft 33 by only adjusting the rotating shaft 33 to rotate a smaller angle along the circumferential direction, so that the first limiting portion 31 abuts against the floor assembly along the preset direction a, and the locking of the adjusting assembly 30 at the second position is realized.

Referring to fig. 1 and fig. 2 again, in some embodiments, when the adjusting assembly 30 is located at the second position, the second matching portion 21 can move in the first direction (not shown) to drive the rotating shaft 33 to rotate in the circumferential direction. Wherein, the first direction is different from the circumferential direction of the rotating shaft 33.

When the adjusting assembly 30 is located at the second position, the first position-limiting portion 31 and the second notch 112 are separated from each other. At this time, the second matching portion 21 is controlled to move along the first direction, so as to drive the rotating shaft 33 to rotate along the circumferential direction, and thus the first limiting portion 31 and the second notch 112 are arranged in a mutually staggered manner in the axial direction of the rotating shaft 33. Therefore, the first limiting portion 31 can abut against the chassis component along the preset direction a, so that the adjusting component 30 is locked at the second position, and the adjustment and fixation of the distance between the head component 20 and the chassis component 10 can be completed.

In some embodiments, the second position-limiting portion 32 is configured as a first gear sleeved on the rotating shaft 33 along the axial direction of the rotating shaft 33, and the second matching portion 21 is configured as a second gear engaged with the first gear, and the axial direction of the second gear intersects with the axial direction of the first gear.

Specifically, the first direction is a circumferential direction of the second gear, and the movement of the second matching portion 21 in the first direction is a rotation of the second gear in the circumferential direction.

Further, the first gear and the second gear are meshed with each other, and the axial direction of the second gear is perpendicular to the axial direction of the first gear. The second gear is fixed on the head assembly 20, so that the second gear can be controlled to rotate along the circumferential direction by adjusting the pitch angle of the head assembly 20. Further, the second gear drives the first gear to rotate along the circumferential direction of the first gear, and the first gear drives the rotating shaft 33 to rotate synchronously. Therefore, the first limiting part 31 and the second notch 112 are staggered in the axial direction of the rotating shaft 33, the first limiting part 31 can be pressed against the chassis assembly 10 downwards under the action of self gravity, and the locking of the head assembly 20 is realized.

Through the structure, when the adjusting component 30 moves from the first position to the second position, the head component 20 can be locked on the height of the adjusting component 30 at the second position only by adjusting the pitching angle of the head component 20, the operation is simple and convenient, the structure is simple, and the locking reliability is high.

Referring to fig. 1, 11 and 12, in some embodiments, the adjusting assembly 30 includes a first cover 34, the shaft 33 is fixedly connected to the first cover 34 and located in the first cover 34, and the first cover 34 is movably disposed on the chassis assembly 10 along an axial direction of the shaft 33.

The first cover 34 can move along the axial direction of the rotating shaft 33 synchronously with the rotating shaft 33, and the rotating shaft 33 is accommodated in the first cover 34, so that the rotating shaft 33 can be protected to a certain extent, and the overall structure of the air outlet device 100 can be more beautiful.

In some embodiments, the chassis assembly 10 includes a base 12 and a second cover 13, the second cover 13 is fixed on the base 12, and the first matching portion 11 is disposed on the second cover 13. The first cover 34 is movably disposed on the second cover 13 along the axial direction of the rotating shaft 33.

Specifically, the second cover 13 is fixed on the base 12, and the sliding slot is opened at the top of the second cover 13, so that the rotating shaft 33 can be inserted into the sliding slot from top to bottom and can move back and forth in the sliding slot, thereby adjusting the height of the handpiece assembly 20.

In addition, the first cover 34 is slidably fitted on the second cover 13, that is, the first cover 34 is slidably connected to the second cover 13 along the axial direction of the rotating shaft 33. Specifically, the first cover 34 and the second cover 13 may be slidably connected through a sliding slot and a sliding block, and certainly, may also be slidably connected through other structures, which is not described herein.

When the rotating shaft 33 reciprocates in the sliding slot, the first cover 34 can move along the predetermined direction a relative to the second cover 13 following the rotating shaft 33.

In some embodiments, handpiece assembly 20 includes a protective cover 22 and a blade 23, blade 23 is rotatably disposed in protective cover 22, and second mating portion 21 is disposed on protective cover 22.

Specifically, the fan blade 23 generates an air flow by rotating, thereby realizing the blowing function of the air outlet device 100. The second gear is fixed on the protective cover 22, and when the pitch angle of the protective cover 22 is adjusted, the fan blades 23 inside the protective cover 22 move synchronously along with the protective cover 22. Meanwhile, the protective cover 22 drives the second gear fixed thereon to rotate, so as to drive the first gear engaged therewith to rotate, and then the rotating shaft 33 is driven to rotate, so as to lock the protective cover 22 and the fan blade 23.

It will be appreciated that the second gear may be secured to the boot 22 by a screw and stud engagement. And the second gear is inserted into the first cover 34 before the second gear is fixed to the protection cover 22, so that the second gear can be smoothly meshed with the first gear. Then, the second gear is fixed to the protection cover 22, so that the first cover 34 is sandwiched between the second gear and the protection cover 22.

In some embodiments, the handpiece assembly 20 further includes a driving member (not shown) in driving connection with the fan blade 23, and the driving member is used for driving the fan blade 23 to rotate.

The driving member can drive the fan blade 23 to rotate inside the protecting cover 22, so as to realize the blowing function of the air outlet device 100. Specifically, the driving member may be configured as a motor or other driving structure, which is not described herein.

Based on the same concept as the air outlet device 100, the present application further provides a fan, including the air outlet device 100 as described above.

When this application is used specifically, place base 12 on ground or desktop, upwards mention safety cover 22, pivot 33 rebound in the spout, because first spacing portion 31 is located second notch 112 this moment, therefore pivot 33 can't rotate, can only rebound.

When the protection cover 22 moves upward to a target height, the first position-limiting portion 31 moves to the outside of the second notch 112, and the rotation shaft 33 can rotate. When the pitch angle of the protection cover 22 is adjusted, the second gear on the protection cover 22 rotates, so that the first gear meshed with the second gear rotates. The first gear drives the rotating shaft 33 to rotate, so that the first limiting portion 31 is staggered with the second notch 112 in the axial direction of the rotating shaft 33, and the first limiting portion 31 can be pressed against the second cover 13 under the action of gravity to lock the protecting cover 22 at a target height.
