Referring to fig. 1 to 4, an embodiment of the present utility model provides a fan 100, which includes a fan body 10 and a mounting bracket 30. The mounting bracket 30 includes a hanging portion 31 (as shown in fig. 7) and a sliding portion 35, and is slidably connected to the fan body 10 along a first direction (X direction as shown in fig. 2) by the sliding portion 35, and is capable of sliding to be flush with one end of the fan body 10 in the first direction.

It will be appreciated that, in order to perform its normal function, the fan body 10 includes a housing 11, a fan wheel 13 provided in the housing 11, and the like. In the first direction, the length of the mounting bracket 30 is smaller than the length of the fan body 10. In use, the fan 100 can be hung on a mounting target by the hanging portion 31 by sliding the mounting bracket 30 to a proper position. In this embodiment, the fan 100 may be a hanging fan, and the main installation target is an edge of a display screen and similar structures, and the matching manner is hanging, in other embodiments, other structures may be used as the main installation target, and the fan may be matched by other manners such as clamping, which is not limited herein. In addition to hanging, the fan 100 may have an erect state on the basis that the mounting bracket 30 can slide relative to the fan body 10, and the fan 100 may also be directly arranged on the placement surface in the first direction by sliding the mounting bracket 30 to be flush with one end of the fan body 10, and then under the support of the mounting bracket 30, the placement surface includes, but is not limited to, a desktop or the like.

The fan 100 can realize the corresponding function by sliding the mounting bracket 30 to a proper position with respect to the fan body 10. The hanging part 31 of the mounting bracket 30 can be hung on a mounting target, or the mounting bracket 30 can be slid to be flush with one end of the fan body 10, so that the fan body is stably placed on a placing surface under the support of the mounting bracket 30. When placed, the mounting bracket 30 corresponds to a stand that provides support. Therefore, the fan 100 can adapt to different application situations by sliding the mounting bracket 30, and can be hung or erected for use.

In addition, the fan 100 can also adapt to different installation targets and installation positions by adjusting the relative position relationship between the installation bracket 30 and the fan body 10 and changing the purging range of the fan 100 without changing the installation targets and the installation positions. Specifically, before the fan 100 is installed, the mounting bracket 30 and the fan body 10 are driven to slide relatively to change the relative positional relationship therebetween, or after the fan 100 is installed, the mounting bracket 30 is kept stationary, and the fan body 10 is driven to move to change the relative positional relationship therebetween.

In view of the balance, the mounting bracket 30 is most stable to fix the fan 100 when it is positioned at the middle position of the fan body 10 in the first direction. Therefore, when the fan 100 is hung, the mounting bracket 30 is preferably adjusted to the middle position of the fan body 10 in the first direction, and the state of the fan 100 at this time is referred to as a hung state.

Further, the fan wheel 13 of the fan 100 is a cross-flow wind wheel, and is axially disposed in the housing 11 along the first direction. Accordingly, the housing 11 has a long strip shape, and the longitudinal direction coincides with the first direction.

With the through-flow impeller type fan wheel 13, the fan 100 can form an air flow in a wide range. In use, the fan 100 may be disposed horizontally in a first direction to substantially cover the width of the display screen and to supply air to a user in front of the display.

Further, the housing 11 includes a wind wheel portion 111 and an air outlet portion 113, the wind wheel portion 111 is formed with a cavity for accommodating the wind wheel portion 111 and an air inlet J communicated with the cavity, and the air outlet portion 113 is formed with an air outlet duct F and an air outlet C communicated with the cavity.

The housing 11 also serves as a volute for the fan wheel 13, participates in the formation of air flow, guides the air flow from the air inlet J to the air outlet C, and finally is blown out from the air outlet C. The air outlet C is correspondingly elongated, and a deflector 15 may be disposed in the air outlet duct F, for guiding the air flow to better blow to the user.

Referring to fig. 5 and 6, a supporting end surface S is configured at one end of the mounting bracket 30 in the first direction, and when the mounting bracket 30 is flush with one end of the fan body 10 in the first direction, the supporting end surface S is flush with the end surface of the fan body 10.

The supporting end face S is flush with the end face of the fan body 10 where the mounting bracket 30 is located in the first direction, specifically, if the end face of the end is a plane perpendicular to the first direction, the supporting end face S is flush with the end face of the end, and if the end face of the end is a plane, a curved surface or an irregular surface at other angles with the first direction, the supporting end face S is flush with the vertex of the end in the first direction.

It is easy to understand that the fan 100 may also be directly erected on the placement surface along the first direction through one end, and the fan 100 is placed on a table surface to be used as a tower fan. When the fan 100 is erected, the supporting end face S of the mounting bracket 30 can be contacted with the placement surface, so that the supporting surface of the fan 100 is widened, and the stability of the fan 100 erected is improved. Preferably, the end surfaces of the two ends of the housing 11 in the first direction are planes perpendicular to the first direction so as to enhance the degree of stability in standing use.

In other embodiments, the mounting bracket 30 may also have two support end surfaces S, and one of the support end surfaces S may be made flush with one end of the fan body 10 by sliding or the other support end surface S may be made aligned with the other end of the fan body 10 by sliding. At this time, both ends of the fan body 10 are available for standing by the slide mounting bracket 30.

Further, the housing 11 of the fan body 10 is configured with a chute H extending in the first direction. The mounting bracket 30 is disposed on the housing 11, and the sliding portion 35 is a sliding rail that mates with the sliding slot H. The mounting bracket 30 is slidably connected to the fan body 10 through its slide rail.

Preferably, the sliding rail is embedded in the sliding groove H, and is connected with the hanging portion 31 through a notch of the sliding groove H, and a width of the notch of the sliding groove H in a direction perpendicular to the first direction is smaller than that of the sliding rail, so that the sliding rail can slide along the first direction and cannot be separated from the sliding groove H through the notch.

Referring to fig. 7 to 9, further, the hanging portion 31 includes a hook plate 311 and a supporting plate 313, which extend along the first direction but are not coplanar, and an end surface of one end of the hook plate 311 and the supporting plate 313 in the first direction is a part of the supporting end surface S.

Taking the display screen as an installation target, in the non-coplanar hook plate 311 and the supporting plate 313, the hook plate 311 is used for hooking on one of the front surface and the back surface of the upper edge of the display screen, and the supporting plate 313 is supported on the other, so that the width direction of the display screen is the first direction. With this, when the fan 100 is to be mounted on a display screen for use, the fan can be hung on the display screen in a hanging state. When the fan 100 needs to be vertically arranged on a desktop for use, the end surfaces of one ends of the hook plate 311 and the supporting plate 313 in the first direction can be placed on the desktop, and because the hook plate 311 and the supporting plate 313 are not coplanar, the projections of the hook plate 311 and the supporting plate 313 in the first direction are not overlapped or are not completely overlapped, so that a larger supporting area is facilitated, and the fan 100 is more stable when in a vertical state.

Specifically, the hanging portion 31 further includes a base plate 315, and the hook plate 311 and the holding plate 313 are disposed on one side of the base plate 315 and parallel to each other. The base plate 315 has two mutually bent sections, wherein the first section 3151 abuts against the air outlet portion 113, the second section 3153 abuts against the wind wheel portion 111, the hook plate 311 is disposed on the first section 3151, and the supporting plate 313 is disposed on the second section 3153. It can be seen that since the fan wheel 13 is provided to the wind wheel portion 111, the center of gravity of the fan body 10 is closer to the wind wheel portion 111. When the hook plate 311 hooks the front surface of the display screen, under the action of gravity, one side of the wind wheel portion 111 of the fan body 10 has a downward tilting tendency, and at this time, the supporting plate 313 can support the back surface of the display screen from the other side by using the gravity of the wind wheel portion 111 and the fan wheel 13, so as to realize stable hanging. In addition, one end of the substrate 315 in the first direction may also serve as a part of the support end face S.

More specifically, the sliding rail is configured on a side of the base plate 315 facing away from the hook plate 311 and the supporting plate 313. The sliding groove H is configured at the air outlet portion 113 of the housing 11, and the sliding rail is correspondingly specifically located at a side of the second section 3153 of the base plate 315 facing away from the hook plate 311. The air outlet 113 of the housing 11 is generally relatively flat and thin to form a duct in a particular direction, which is advantageous for arranging the mounting bracket 30.

In some embodiments, the fan 100 further includes a locking mechanism 50, the locking mechanism 50 operatively locking the mounting bracket 30 relative to the fan body 10.

It will be appreciated that the locking mechanism 50 has a locked state and an unlocked state, respectively, and is operable to switch between the two states. In the locked state, the locking mechanism 50 locks the mounting bracket 30 relative to the fan body 10, and the mounting bracket 30 can no longer slide relative to the fan body 10. In the unlocked state, the locking mechanism 50 contacts the locking of the mounting bracket 30, and the mounting bracket 30 is restored to a state in which it can slide with respect to the fan body 10.

After the mounting bracket 30 is slid into place, it can be locked by a locking mechanism 50 to maintain stability in this position.

Further, the fan body 10 is configured with a plurality of locking grooves K (as shown in fig. 10) on the sliding path of the mounting bracket 30, and the locking mechanism 50 is disposed on the mounting bracket 30 and is configured with a tooth button 511, wherein the tooth button 511 is operable to be alternatively locked into the locking grooves K. Specifically, the clamping grooves K are configured in the sliding groove H, all the clamping grooves K are arranged along the first direction, and preferably all the clamping grooves K are distributed throughout the sliding groove H along the first direction.

The tooth buckle 511 is a tooth-shaped structure configured on the locking mechanism 50, and has a protruding direction consistent with the groove depth direction of the clamping groove K, and is capable of being operatively clamped into the clamping groove K, and generating a limiting effect on the mounting bracket 30 in the first direction after being clamped into the clamping groove K. The tooth buckles 511 of the locking mechanism 50 are clamped into different clamping grooves K, namely the mounting bracket 30 is correspondingly locked at different positions, namely the locking state of the locking mechanism 50, and when the tooth buckles 511 are separated from the clamping grooves K, the mounting bracket 30 can restore to move relative to the fan body 10, namely the unlocking state of the locking mechanism 50.

It will be appreciated that there is one slot K in the plurality of slots K, and when the tooth buckle 511 is snapped into the slot K, the supporting end surface S of the mounting bracket 30 is aligned with one end of the fan body 10, in other words, the fan 100 is in the standing state. Similarly, there is a slot K, and when the tooth buckle 511 is snapped into the slot K, the mounting bracket 30 is located at the middle position of the fan body 10 in the first direction, in other words, the fan 100 is in a hanging state. In addition, other clamping grooves K may exist in the plurality of clamping grooves K, so that the mounting bracket 30 and the fan body 10 can be located at different relative positions.

Further, the locking mechanism 50 includes a locking member 51 and an elastic member 53, the tooth buckle 511 is configured on the locking member 51, the locking member 51 can move along a direction in which the tooth buckle 511 is clamped into the clamping groove K, and the elastic member 53 abuts against the locking member 51 and is configured to provide an elastic force for driving the tooth buckle 511 to clamp into the clamping groove K.

When the tooth buckle 511 is aligned to the clamping groove K, the tooth buckle 511 can be clamped into the clamping groove K and maintain in the clamping groove K under the driving of the elastic member 53. When unlocking is needed, the locking piece 51 is driven to move in the reverse direction by overcoming the elastic force until the tooth buckle 511 is separated from the clamping groove K. Wherein the elastic member 53 may be a spring.

Specifically, the locking piece 51 is also configured with an operation portion 513, facilitating the pressing operation. The locking mechanism 50 comprises two locking pieces 51, and faces to two opposite sides respectively, and correspondingly, two opposite sides in the chute H are provided with clamping grooves K, so that the locking mechanism 50 can stably form locking. In addition, the locking mechanism 50 further includes a mounting member 55, the mounting member 55 is disposed on the base plate 315, and the locking member 51 and the elastic member 53 are mounted on the mounting member 55. The mounting member 55 is formed with a guide groove Y for guiding the movement of the locking member 51, the direction of the guide groove Y is the direction in which the tooth buckle 511 is engaged with the engagement groove K, the locking member 51 is configured with a stopper 515, and the stopper 515 is disposed to pass through the guide groove Y and is slidable along the guide groove Y in the guide groove Y.

When the fan 100 is to be hung and used, the locking member 51 is pressed by the operation portion 513 to separate the tooth buckle 511 from the locking groove K against the elastic force. After losing the lock of the locking mechanism 50, the mounting bracket 30 can slide along the sliding groove H of the first direction through the sliding rail. When slid to the proper position, the locking member 51 is released, and the tooth buckle 511 is again caught in the catching groove K by the driving of the elastic member 53, and the mounting bracket 30 is again locked. At this time, the fan 100 may be hung on the display screen through the mounting bracket 30. The fan 100 is preferably hung in a hanging state, and for the purpose of adjusting the air outlet range or adapting to the installation position, the installation bracket 30 can be adjusted to a proper position before being hung on the display screen, or the installation bracket 30 can be kept still after being hung on the display screen, and after unlocking, the fan body 10 is driven to move to a proper position.

When the fan is required to be used vertically, the mounting bracket 30 is moved to one end of the fan body 10, the supporting end surface S of the mounting bracket is flush with one end of the fan body 10, and the tooth buckles 511 of the locking piece 51 are clamped into corresponding clamping grooves K. In this way, the fan 100 is in the erectable state, and the fan 100 can be used in an erected state with the support of the mounting bracket 30.

The fan 100 can adapt itself to different application scenarios by sliding the mounting bracket 30. In the erect state, the fan 100 can stably stand on the target surface by means of the mounting bracket 30 without an additional base.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
