Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the description of the present invention, it should be understood that the azimuth or positional relationships indicated by the azimuth terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal", and "top, bottom", etc., are generally based on the azimuth or positional relationships shown in the drawings, merely to facilitate description of the present invention and simplify the description, and these azimuth terms do not indicate and imply that the apparatus or elements referred to must have a specific azimuth or be constructed and operated in a specific azimuth, and thus should not be construed as limiting the scope of protection of the present invention; the orientation word "inner and outer" refers to inner and outer relative to the contour of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "upper surface on … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In addition, the terms "first", "second", etc. are used to define the components, and are only for convenience of distinguishing the corresponding components, and the terms have no special meaning unless otherwise stated, and therefore should not be construed as limiting the scope of the present invention.

Referring to fig. 1-6 in combination, according to an embodiment of the present invention, a fan is provided that includes a support frame 2, a fan head 1, and a drive mechanism. The fan head 1 is movably arranged on the support frame 2. The support frame 2 is used for bearing the fan head 1, and the support frame 2 can directly or indirectly bear the fan head 1. The fan head 1 can be lifted and lowered on the support frame 2. The driving mechanism is connected with the fan head 1 through a connecting rope 24. Wherein the driving mechanism can pull the fan head 1 to ascend through the connecting rope 24; and the driving mechanism can loosen the connecting rope 24, so that the fan head 1 descends under the action of self gravity.

In the above example, the fan head 1 can be lifted up by the driving mechanism such as the motor 25, and can be lowered down by its own weight when the driving mechanism releases the connecting rope 24, so that the purpose of lifting the fan head 1 on the support frame 2 can be achieved. And compared with the prior art, the invention at least omits the use of the elastic piece 21, thereby simplifying the structure and reducing the cost.

In order to implement the function of the aforementioned driving mechanism, the driving mechanism may include a motor 25, one end of which is connected to an output shaft 251 of the motor, and the other end of which 24 is connected to the fan head 1, so that the driving mechanism can pull the connection rope 24 or release the connection rope 24, as shown in fig. 3 and 4. Specifically, one end of the connection cord 24 may be tied to the output shaft 251 of the motor, and the other end may be tied to the fan head 1.

The driving mechanism winds the connecting rope 24 through the forward rotation of the motor 25, so that the connecting rope 24 pulls the fan head 1, and the fan head 1 rises under the pulling of the connecting rope 24. The driving mechanism also releases the connecting rope 24 by reversing the motor 25 to release the connecting rope 24, so that the fan head 1 can descend under the action of self gravity.

In the above example, the motor 25, the connecting rope 24 and the fan head 1 are matched, when the motor 25 rotates forward, the fan head 1 can be pulled to rise, and when the motor 25 rotates backward, the fan head 1 can descend under the action of self gravity.

In some embodiments, as shown in fig. 3 and 4, the output shaft 251 of the motor may be sleeved on the drum 26, and one end of the connection rope 24 may be connected to the drum 26 to be connected to the output shaft 251 of the motor through the drum 26.

In some embodiments, as shown in fig. 5, the support frame 2 may be provided with a first support member 23, and the first support member 23 may be provided with a support wire slot, through which the connection rope 24 passes. Wherein the first support 23 may be a fixed pulley. In a specific application example, as shown in fig. 1 and 2, the supporting frame 2 may be provided with a chassis 7, the aforementioned motor 25 may be disposed on the chassis 7, and the first supporting member 23 is disposed on the upper portion of the supporting frame 2, and one end of the connecting rope 24 is connected to the output shaft 251 of the motor, and the other end of the connecting rope 24 is connected to the fan head 1 by bypassing the supporting wire slot. The support frame 2 is also provided with a chassis shell 6, and the chassis 7 is positioned in the chassis shell 6. The support frame 2 may be provided with a support frame housing 3. The support frame 2 has a semicircular support bar 4 and an arc-shaped support bar 5. Both the semicircular support bar 4 and the arc-shaped support bar 5 are used to provide support to the body of the support frame.

In some embodiments, the aforementioned fan may further include a stopper for limiting the movement of the connection rope 24 to move the connection rope 24 along a set trajectory.

In the above example, the stopper is provided to restrict the direction of the connecting rope 24, so that the connecting rope 24 does not shake left and right during movement. In one specific example of an application, the stop may limit the retraction of the connecting cord 24 from the center of the drum 26.

In order to implement the function of the aforementioned stopper, the stopper may limit the movement of the connection rope 24, and as shown in fig. 3 and 4, the stopper may include a stopper 29 provided on the support frame 2, and the stopper 29 may be fixed on the support frame 2. The stopper 29 is provided with a limiting via hole 291 through which the connection rope 24 passes, and the stopper limits the movement of the connection rope 24 through the limiting via hole 291.

As shown in fig. 3 and 4, the aforementioned support frame 2 may be provided with a second support member 27, and the second support member 27 is used to provide support for the motor 25. The support frame 2 may be provided with a third support 28, the third support 28 being adapted to provide support to the drum 26 as described above.

In some embodiments, the foregoing fan may further include a clamping jaw mechanism for clamping the fan head 1 when the fan head 1 moves to the set position to limit the fan head 1. The jaw mechanism is also driven to open by the self-weight of the fan head 1 in the set position when the drive mechanism releases the connecting cord 24 to release the fan head 1.

In the above example, when the fan head 1 moves to the setting position, the clamping jaw mechanism clamps the fan head 1, which is advantageous to improve the stability of the fan head 1 at the setting position, prevent the fan head 1 from shaking, and enable the fan head 1 to stably operate at the setting position. When the driving mechanism releases the connecting rope 24, the fan head 1 drives the clamping jaw mechanism to open under the action of self gravity, so that the clamping jaw mechanism releases the fan head 1, and the fan head 1 can smoothly descend. The fan head 1 can be automatically unlocked under the action of gravity, so that a manual or electric unlocking structure is omitted, and the fan head is more convenient to use.

To perform the function of the jaw mechanism described above, the jaw mechanism described above may comprise a first jaw 17 and a second jaw 18, both of the first jaw 17 and the second jaw 18 being movably arranged on the support frame 2, e.g. both of the first jaw 17 and the second jaw 18 may be rotatably arranged on the support frame 2. Wherein both the first jaw 17 and the second jaw 18 can be opened or closed relatively. The jaw mechanism clamps the fan head 1 by relatively closing both the first jaw 17 and the second jaw 18, and the jaw mechanism unclamps the fan head 1 by relatively opening both the first jaw 17 and the second jaw 18.

In the above example, both the first jaw 17 and the second jaw 18 clamp the fan head 1 when relatively closed and unclamp the fan head 1 when relatively open, so that the function of the foregoing jaw mechanism can be achieved, so that the jaw mechanism clamps or unclamps the fan head 1.

In some embodiments, when the driving mechanism releases the connecting rope 24, the fan head 1 located at the set position can drive the first clamping jaw 17 and/or the second clamping jaw 18 to move through the first driving inclined plane 161 under the action of self gravity, so that the first clamping jaw 17 and the second clamping jaw 18 are relatively opened.

When the fan head 1 located at the set position drives only the first clamping jaw 17 to move under the action of gravity by the first driving inclined plane 161, the first driving inclined plane 161 may be disposed only on the fan head 1, may be disposed only on the first clamping jaw 17, or may be disposed on both the fan head 1 and the first clamping jaw 17. Similarly, when the fan head 1 located at the set position drives only the second clamping jaw 18 to move under the action of its own gravity through the first driving inclined plane 161, the first driving inclined plane 161 may be disposed only on the fan head 1, or may be disposed only on the second clamping jaw 18, or may be disposed on both the fan head 1 and the second clamping jaw 18. When the fan head 1 at the set position drives the first clamping jaw 17 and the second clamping jaw 18 to move simultaneously under the action of self gravity through the first driving inclined plane 161, the first driving inclined plane 161 can be arranged on the fan head 1 only, can be arranged on the first clamping jaw 17 and the second clamping jaw 18 only, and can also be arranged on the fan head 1, the first clamping jaw 17 and the second clamping jaw 18.

In the above example, the purpose of pushing the first clamping jaw 17 and/or the second clamping jaw 18 to move under the action of gravity of the fan head 1 to enable the first clamping jaw 17 and the second clamping jaw 18 to be relatively opened can be achieved by adopting a bevel matching mode.

What needs to be explained here is: the first driving inclined surface 161 may be a plane surface or an arc surface.

In a specific application example, both the first jaw 17 and the second jaw 18 described above may be rotating members and both are rotatably connected to the support frame 2 through the middle portion. The middle parts of the first clamping jaw 17 and the second clamping jaw 18 can be rotatably connected with the support frame 2 through a rotating shaft 170. Both the first clamping jaw 17 and the second clamping jaw 18 mutually cooperate through their respective ends to clamp the fan head 1. The fan head 1 located at the set position drives the other end of the first clamping jaw 17 and/or the other end of the second clamping jaw 18 through the first driving inclined plane 161 under the action of self gravity, so that the corresponding clamping jaws move to enable the first clamping jaw 17 and the second clamping jaw 18 to be opened relatively.

In the above example, the first clamping jaw 17 and the second clamping jaw 18 are both opened and closed in a rotating manner, so that the first clamping jaw 17 and the second clamping jaw 18 clamp or unclamp the fan head 1.

As shown in fig. 6, the first jaw 17 and the second jaw 18 may be assembled from two or more parts. Similarly, the support frame 2 may be assembled from two or more components.

In some embodiments, as shown in fig. 5 and 6, the aforementioned fan may further include an elastic member 21, the elastic member 21 for providing a force for relatively closing both the first jaw 17 and the second jaw 18.

In the above example, the elastic member 21 may be a spring or a flexible plastic or the like. When the fan head 1 moves to the set position, the elastic member 21 can automatically clamp and lock the fan head 1, so that the effect of saving manpower is achieved, and automatic operation is facilitated.

More than two elastic members 21 can be arranged at the first clamping jaw 17 and the second clamping jaw 18 to facilitate pushing the first clamping jaw 17 and the second clamping jaw 18 to be automatically closed.

As shown in fig. 5 and 6, the support frame 2 may be provided with a support block 19, and the support block 19 may be fixed to the support frame 2. The number of support blocks 19 is two, one support block 19 being provided at the first jaw 17 and the other support block 19 being provided at the second jaw 18. Two support blocks 19 provide support for elastic members 21 at the first jaw 17 and the second jaw 18, respectively.

In some embodiments, when the first clamping jaw 17 and the second clamping jaw 18 cooperate with each other to clamp the fan head 1 through one end, the fan head 1 at the set position drives the other end of the first clamping jaw 17 and/or the other end of the second clamping jaw 18 through the first driving inclined plane 161 under the action of self gravity, so that when the corresponding clamping jaws move,

As shown in fig. 5 and 6, the fan head 1 may be provided with a first connecting block 16, and the fan head 1 located at the set position drives the first driving inclined plane 161 to move under the action of its own gravity through the first connecting block 16, so that the first driving inclined plane 161 drives the other end of the first clamping jaw 17 and/or the other end of the second clamping jaw 18, so that the first clamping jaw 17 and the second clamping jaw 18 are opened relatively. Wherein the first connecting block 16 is configured to be located on the upper side of the other ends of both the first clamping jaw 17 and the second clamping jaw 18 when the fan head 1 moves to the aforementioned setting position. When the fan head 1 moves from the lower direction to the set position, the first connecting block 16 drives the other end of the first clamping jaw 17 and/or the other end of the second clamping jaw 18 to move through the second driving inclined surface 162, so that the other ends of the first clamping jaw 17 and the second clamping jaw 18 can be relatively opened against the resistance of the elastic member 21, and the first connecting block 16 can move to the upper side of the other ends of the first clamping jaw 17 and the second clamping jaw 18.

Wherein, due to the action of the elastic member 21, the first clamping jaw 17 and the second clamping jaw 18 are in a relatively closed state in the initial state, and when the fan head 1 is to be moved to the set position, the resistance of the elastic member 21 needs to be overcome, so that the other ends of the first clamping jaw 17 and the second clamping jaw 18 can be opened, and the first connecting block 16 can be moved above the other ends of the first clamping jaw 17 and the second clamping jaw 18. In the above example, by means of the engagement of the second driving ramp 162, it is achieved that the first connecting block 16 can push the other end of the first jaw 17 and/or the other end of the second jaw 18 relatively open when moving upward, enabling the first connecting block 16 to move to the upper side of the other ends of both the first jaw 17 and the second jaw 18.

What needs to be explained here is: the second driving inclined surface 162 may be a plane surface or an arc surface.

In some embodiments, as shown in fig. 5 and 6, the fan head 1 may further be provided with a second connection block 20, and the second connection block 20 may be fixed to the fan head 1. The fan head 1 is clamped by the first clamping jaw 17 and the second clamping jaw 18 via the second connecting block 20. Wherein, one end of the first clamping jaw 17 and one end of the second clamping jaw 18 are respectively provided with a hook 180, two clamping tables 200 are arranged on the second connecting block 20, and when the fan head 1 moves to the set position, the first clamping jaw 17 and the second clamping jaw 18 are respectively hooked on the corresponding clamping tables 200 in a one-to-one correspondence through the respective hook 180.

In the above example, the hooking portions 180 provided on the first clamping jaw 17 and the second clamping jaw 18 hook the clamping table 200 on the fan head 1, so that the fixing effect on the fan head 1 can be further improved, and the stability of the fan head 1 in the set position can be further improved.

In order to improve the lifting stability of the fan head 1, the second connecting block 20 may be provided with a sliding block, and the supporting frame 2 may be provided with a limiting chute, where the second connecting block 20 is slidably matched with the limiting chute through the sliding block so as to lift along the limiting chute.

In some embodiments, as shown in fig. 5 and 6, when the first clamping jaw 17 and the second clamping jaw 18 are both rotating members and are both connected with the support frame 2 in a rotating manner through the middle portion, and the first clamping jaw 17 and the second clamping jaw 18 are mutually matched to clamp the fan head 1 through respective one ends, a third driving inclined plane 201 may be disposed on the second connecting block 20, the clamping table 200 is located at the lower side of the third driving inclined plane 201, and when the second connecting block 20 moves from the lower direction to the set position, the second connecting block 20 can drive one ends of the first clamping jaw 17 and the second clamping jaw 18 to be relatively opened through the third driving inclined plane 201, so that the second connecting block 20 can drive the clamping table 200 to move to the hook 180 of the first clamping jaw 17 and the second clamping jaw 18, so that the hook 180 of the first clamping jaw 17 and the second clamping jaw 18 hook the corresponding clamping table 200 in a one-to-one correspondence manner.

In the above example, by adopting the way that the third driving inclined plane 201 is matched, the purpose that the second connecting block 20 can push one end of the first clamping jaw 17 and one end of the second clamping jaw 18 to be relatively opened when moving upwards, so that the second connecting block 20 drives the clamping table 200 to move to the hook 180 of the first clamping jaw 17 and the second clamping jaw 18 can be achieved.

In some embodiments, the number of the jaw mechanisms may be more than two, and the number of the set positions is equal to and corresponds to the number of the jaw mechanisms one by one. Wherein the fan head 1 is clamped by different jaw mechanisms when it is moved to different setting positions.

In the above example, more than two setting positions may be preset, and one clamping jaw mechanism may be disposed at each setting position, so that when the fan head 1 moves to each setting position, the fan head 1 may be clamped and fixed by the corresponding clamping jaw mechanism, so that the fan head 1 may be kept stable at different setting positions.

What needs to be explained here is: the setting positions comprise a first setting position and a second setting position, and the first setting position is positioned below the second setting position. When the fan head 1 drives the second connecting block 20 to move from the first setting position to the second setting position, the second connecting block 20 can drive the first clamping jaw 17 and the second clamping jaw 18 at the first setting position to open relatively through the third driving inclined plane 201, so that the second connecting block 20 can pass through the first clamping jaw 17 and the second clamping jaw 18 at the first setting position. When the fan head 1 drives the second connecting block 20 to move from the second setting position to the first setting position, the second connecting block 20 can drive the first clamping jaw 17 and the second clamping jaw 18 at the first setting position to open relatively through the fourth driving inclined plane 202, so that the second connecting block 20 can pass through the first clamping jaw 17 and the second clamping jaw 18 at the first setting position.

The third driving inclined plane 201 and the fourth driving inclined plane 202 may be a plane or an arc plane.

For ease of understanding, the overall structure of the invention is described below and its working principle is explained.

In a specific implementation, the user only needs to touch the start switch of the motor 25, the motor 25 is started, and the motor 25 releases the connecting rope 24 according to the set height.
