When the traditional fan is assembled, a mounting hole needs to be formed in the adjusting piece, and a screw penetrates through the mounting hole in the adjusting piece and extends into the mounting hole in the rotating shaft. So, on the one hand, produce certain destruction to the regulating part, on the other hand, the screw passes the regulating part and is difficult to fix a position the assembly with the mounting hole in the pivot, and the assembly degree of difficulty is higher and the assembly is complicated. In view of this, the present application proposes a fan structure 10 that is efficient in assembly of the fan structure 10.

Specifically, referring to fig. 1 and 2, the fan structure 10 in an embodiment includes a motor 100, a mounting sleeve 200, and an adjusting member 300, wherein the motor 100 can drive a fan blade to rotate to generate an air flow, and the motor 100 is mounted on the adjusting member 300 through the mounting sleeve 200. Specifically, in one of the embodiments, the adjusting member may be a pitch adjusting member, and the motor 100 is driven to rotate or swing by the rotation of the adjusting member 300 to implement pitch adjustment of the outlet air body. In other embodiments, the adjustment member may also be mounted using a mounting-like action power supply.

As an alternative connection manner of the motor 100 and the mounting sleeve 200, please refer to fig. 3 and 4, in one embodiment, the motor 100 includes a rotating shaft 110, the mounting sleeve 200 is provided with a first mounting hole 222, the rotating shaft 110 is inserted into the first mounting hole 222, and the rotating shaft 110 is rotatably connected to the mounting sleeve 200 so that the motor 100 can drive the air outlet main body to rotate to adjust the air outlet angle of the air outlet main body.

When the fan structure 10 of the present application is assembled, the rotating shaft 110 is inserted into the first mounting hole 222, and the rotating shaft 110 is rotatably connected to the mounting sleeve 200, so that the motor 100 can drive the air outlet main body to rotate to adjust the air outlet angle of the air outlet main body when rotating, and in addition, the rotating shaft 110 is rotatably connected to the mounting sleeve 200 to prevent the rotating shaft 110 from being separated from the first mounting hole 222; and then, the mounting sleeve 200 is connected with the adjusting piece 300, and the rotating shaft 110 is indirectly mounted on the adjusting piece 300, so that compared with the traditional fan assembly, the fan assembly does not need accurate positioning, is simple to assemble and has higher efficiency.

Referring to fig. 3 and 5, as an alternative implementation manner of the rotatable connection between the rotating shaft 110 and the mounting sleeve 200, in one embodiment, the mounting sleeve 200 is provided with a first mounting portion 224, the rotating shaft 110 is provided with a second mounting portion 112 that is in concave-convex fit with the first mounting portion 224, when the rotating shaft 110 is inserted into the first mounting hole 222, the first mounting portion 224 and the second mounting portion 112 are in concave-convex fit, and the rotating shaft 110 can rotate relative to the first mounting portion 224 along the circumferential direction of the first mounting hole 222. The purpose of the rotation shaft 110 rotating along the circumferential direction of the first mounting hole 222 is to drive the air outlet main body to rotate along the circumferential direction of the first mounting hole 222 so as to change the air outlet angle of the air outlet main body. The rotation of the driving shaft 110 can be driven by the motor 100 or by a link mechanism. The driving source only needs to be capable of driving the rotating shaft 110 to rotate, and is not described in detail herein.

Optionally, referring to fig. 4 and 5, in one embodiment, the first mounting portion 224 is a mounting protrusion, and the second mounting portion 112 is a fourth mounting hole; or the first mounting portion 224 is a fourth mounting hole and the second mounting portion 112 is a mounting projection. Thus, the mounting protrusion extends into the fourth mounting hole, so that the rotation of the rotating shaft 110 relative to the first mounting hole 222 is not limited, and the rotating shaft 110 can be limited.

Further, in order to achieve positioning and installation between the rotating shaft 110 and the mounting sleeve 200, so as to assemble the rotating shaft 110 and the mounting sleeve 200 more conveniently, referring to fig. 4, 5 and 6, in one embodiment, the rotating shaft 110 further includes a first positioning portion 114, and the mounting sleeve 200 is further provided with a second positioning portion 230, and when the first positioning portion 114 and the second positioning portion 230 are positioned and matched, the first mounting portion 224 and the second mounting portion 112 are in concave-convex matching.

The first limiting part 312 and the second limiting part 214 are engaged with each other in a plurality of ways, for example, the first limiting part 312 and the second limiting part 214 are abutted, clamped or directly fixedly connected with each other, so long as the mounting sleeve 200 can be limited to rotate or move relative to the adjusting member 300 to separate from the adjusting member 300.

Optionally, in one embodiment, referring to fig. 7, the first position-limiting portion 312 includes a first clamping portion 3122, the second position-limiting portion 214 includes a second clamping portion 2142, and the adjusting member 300 is clamped with the mounting sleeve 200 by the clamping fit of the first clamping portion 3122 and the second clamping portion 2142, so that the adjusting member 300 can limit the mounting sleeve 200 from being disengaged from the adjusting member 300 by rotating or moving relative to the adjusting member 300. First joint portion 3122 and second joint portion 2142 when the joint is joined in marriage, be equivalent to the installation cover 200 set firmly on regulating part 300, at this moment, installation cover 200 can't rotate or remove in order to break away from regulating part 300 through relative regulating part 300, first joint portion 3122 and second joint portion 2142 joint cooperation back does not mean that first joint portion 3122 and second joint portion 2142 can not separate. When the first clamping portion 3122 and the second clamping portion 2142 are driven to be separated by an external force, the mounting sleeve 200 and the adjusting member 300 can be detached.

In one embodiment, referring to fig. 7, the first engaging portion 3122 is a first engaging protrusion, the second engaging portion 2142 is a first engaging hole, and the adjusting member 300 is limited by the engaging engagement between the first engaging protrusion and the first engaging hole and the mounting sleeve 200, so that the adjusting member 300 can limit the mounting sleeve 200 from rotating or moving relative to the adjusting member 300 to disengage from the adjusting member 300.

In other embodiments, the first engaging portion 3122 is a first engaging hole, the second engaging portion 2142 is a first engaging protrusion, and the adjusting member 300 is limited by the engaging engagement of the first engaging hole and the first engaging protrusion with the mounting sleeve 200, so that the adjusting member 300 can limit the mounting sleeve 200 from rotating or moving relative to the adjusting member 300 to disengage from the adjusting member 300.

Further, in order to improve the reliability of the limitation of the mounting sleeve 200, in one embodiment, referring to fig. 6 and 7, the first limiting portion 312 further includes a first blocking portion 3124, and the second limiting portion 214 further includes a second blocking portion 2144, when the first engaging portion 3122 and the second engaging portion 2142 are engaged, the first blocking portion 3124 and the second blocking portion 2144 are abutted to limit the mounting sleeve 200 from rotating relative to the adjusting member 300 in a direction crossing the second blocking portion 2144. Thus, even if the first and second snap portions 3122 and 2142 are loosened, the rotation of the mounting sleeve 200 relative to the adjusting member 300 can be restricted in at least one direction to be disengaged from the adjusting member 300.

As such, when the mounting sleeve 200 rotates, the second blocking portion 2144 can rotate along the rotation path of the mounting sleeve 200, and thus more easily fit over the first blocking portion 3124 and the first blocking portion 3124.

In addition, an implementation also relates to a fan, which comprises the fan structure 10 in any one of the above embodiments.

The fan includes the fan structure 10 in any of the embodiments, so that when the fan is assembled, the rotating shaft 110 is inserted into the first mounting hole 222, and the rotating shaft 110 is rotatably connected to the mounting sleeve 200, so that the motor 100 can drive the air outlet main body to rotate to adjust the air outlet angle of the air outlet main body when rotating, and in addition, the rotating shaft 110 is rotatably connected to the mounting sleeve 200 to prevent the rotating shaft 110 from being separated from the first mounting hole 222; subsequently, the mounting sleeve 200 is connected with the adjusting piece 300, and the rotating shaft is indirectly mounted on the adjusting piece 300, so that compared with the traditional fan assembly, the fan assembly does not need accurate positioning, is simple to assemble and has higher efficiency.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
