Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Referring to fig. 1 to 7, the present embodiment provides a fan illumination apparatus including a fixing mechanism 1, a slider-crank mechanism 2, a driving mechanism 3, and a lifting fan illumination mechanism 4.

The fixing mechanism 1 is used for fixing the fan lighting device at a preset mounting position, namely, hanging the fan lighting device at a preset hanging position so as to keep a preset hanging height.

For example, the fixing mechanism 1 may fix the fan lighting device to a ceiling or to a wall. To fixed knot of fixed establishment 1 on ceiling or wall constructs, for example can be provided with trip or buckle for fixed establishment 1's upper surface, be provided with the snap ring on the ceiling, trip or buckle joint are in the snap ring to hang fixed establishment 1 and establish on the ceiling.

In a specific implementation, the fixing mechanism 1 includes a fixing structure 11, an accommodating cavity 12 disposed at the bottom of the fixing structure 11 and having a downward opening, and a power supply device 13 disposed in the accommodating cavity 12. The accommodating cavity 12 may be used to accommodate part of the lifting fan lighting mechanism 4, that is, the top end of the lifting fan lighting mechanism 4 may be disposed in the accommodating cavity 12, so that when power needs to be supplied to the lifting fan lighting mechanism 4, the lifting fan lighting mechanism 4 rises to a position where part of the lifting fan lighting mechanism is located in the accommodating cavity 12 and is connected with the power supply device 13 in the accommodating cavity 12 to realize power on, and the power supply device 13 may specifically be electrically connected with an external power supply.

In the embodiment, the driving mechanism 3 and the slider-crank mechanism 2 can be respectively arranged at the left side and the right side of the fixing mechanism 1, and the driving mechanism 3 is in transmission connection with the lifting fan illuminating mechanism 4, so that when the lifting fan illuminating mechanism 4 needs to be cleaned, the driving mechanism 3 can drive the lifting fan illuminating mechanism 4 to descend to a position where a user can touch or conveniently clean the lifting fan illuminating mechanism 4, and the user can conveniently perform all dust removal cleaning on the lifting fan illuminating mechanism 4; when the cleaning is completed, the driving mechanism 3 drives the lifting fan lighting mechanism 4 to ascend to a preset hanging position.

In a specific implementation, the side wall of the fixing mechanism 1 is provided with a first sliding chute 15, and the first sliding chute 15 can extend along the horizontal direction. The slider-crank mechanism 2 is provided with a push rod 21, the extending direction of the push rod 21 is parallel to the extending direction of the first sliding chute 15, and the push rod 21 is used for sliding fit with the first sliding chute 15. For example, the cross section of the first sliding slot 15 may be a square or a circle, and the cross section of the push rod 21 may be a square section matching the square or a circle section matching the circle.

The specific sliding process is as follows: when the push rod 21 slides towards the direction away from the first sliding groove 15 and slides out of the first sliding groove 15, the lifting fan lighting mechanism 4 releases the supporting effect of the push rod 21 on the lifting fan lighting mechanism, so that the lifting fan lighting mechanism 4 can be separated from the fixing mechanism 1, and the lifting fan lighting mechanism 4 can be driven by the driving mechanism 3 to gradually descend to the height which can be touched by a user.

When the push rod 21 slides along the horizontal direction and slides into the first sliding groove 15 towards the direction close to the first sliding groove 15, the push rod 21 is inserted into the first sliding groove 15 and is connected with the lifting fan illuminating mechanism 4 in a clamping manner, namely, the push rod 21 is supported on the lifting fan illuminating mechanism 4, so that the lifting fan illuminating mechanism is prevented from being separated from the fixing mechanism 1, and the lifting fan illuminating mechanism 4 is further limited from descending.

During the concrete implementation, when lift fan lighting mechanism 4 rises to predetermined hanging position, the top of lift fan lighting mechanism 4 can be located holding chamber 12, and when lift fan lighting mechanism 4 was descended in needs, the top of lift fan lighting mechanism 4 continued to descend after can shifting out from holding chamber 12 to can descend to the position that the user can touch.

For example, when the driving mechanism 3 and the slider-crank mechanism 2 are disposed on the left and right sides (along the x direction in fig. 2) of the fixing mechanism 1, the side wall of the fixing mechanism 1 may be provided with a first sliding slot 15 extending along the y direction shown in fig. 2, and the slider-crank mechanism 2 may drive the push rod 21 connected thereto to move toward or away from the first sliding slot 15.

For example, when the lifting fan lighting mechanism 4 rises to the preset hanging position, the top end of the lifting fan lighting mechanism 4 is located in the accommodating cavity 12, and meanwhile, the push rod 21 can be driven to move towards the first sliding groove 15 and be located in the first sliding groove 15, and the push rod 21 can be supported at the bottom of the top end of the lifting fan lighting mechanism 4 to support and fix the lifting fan lighting mechanism 4, so that the lifting fan lighting mechanism 4 is always kept at the preset hanging height.

When the lifting fan lighting mechanism 4 needs to be lowered for cleaning, the push rod 21 can be driven to move towards the direction away from the first sliding groove 15 and move out of the first sliding groove 15, at the moment, the push rod 21 releases the supporting effect on the lifting fan lighting mechanism 4, namely, the lifting fan lighting mechanism 4 can be driven by the driving mechanism 3 to move out of the accommodating cavity 12 and continue to descend to the preset height, so that a user can clean the lifting fan lighting mechanism 4 conveniently.

In summary, the fan lighting device provided in this embodiment is connected to the lifting fan lighting mechanism 4 through the driving mechanism 3, and is configured to drive the lifting fan lighting mechanism 4 to ascend and descend, so that when the lifting fan lighting mechanism 4 needs to be cleaned, the driving mechanism 3 drives the lifting fan lighting mechanism 4 to descend to a position where a user can touch the lifting fan lighting mechanism, thereby facilitating overall cleaning of the lifting fan lighting mechanism 4, and enabling cleaning cleanliness to be higher; after the cleaning is completed, the driving mechanism 3 drives the lifting fan lighting mechanism 4 to ascend to a preset hanging position for lighting and the like. The first slide groove 15 is provided on the side wall of the fixing mechanism 1, and the slider-crank mechanism 2 has a push rod 21 slidably fitted to the first slide groove 15. When the lifting fan lighting mechanism 4 needs to be landed, the push rod 21 is moved out of the first chute 15, and at the moment, the push rod 21 cannot interfere or influence the landing of the lifting fan lighting mechanism 4; when the lifting fan lighting mechanism 4 is cleaned and lifted to a preset hanging height, the push rod 21 can be moved back into the first sliding groove 15 through the slider-crank mechanism 2 to support the top end of the lifting fan lighting mechanism 4, so that the lifting fan lighting mechanism 4 is supported and fixed to be kept at the preset hanging position after the lifting fan lighting mechanism 4 is lifted to the preset hanging position.

Referring to fig. 1, 6 and 7, in order to make the movement of the push rod 21 more stable, the left and right side walls of the fixing mechanism 1 are respectively provided with a first sliding slot 15, so that the two ends of the push rod 21 are respectively connected with the corresponding first sliding slots 15 in a sliding manner, and when the push rod 21 is arranged in the first sliding slots 15, the push rod 21 can support the lifting fan lighting mechanism 4 more stably and reliably.

Since the elevating fan lighting mechanism 4 can be elevated in the vertical direction (the z direction shown in fig. 2), the extending direction of the first chute 15 may be the horizontal direction, that is, may extend in the x direction shown in fig. 2, or may extend in the y direction shown in fig. 2, specifically, depending on the installation position of the crank slider mechanism 2 on the fixing mechanism 1. In the present embodiment, the first sliding slot 15 extends along the y direction shown in fig. 2, and the following description is given by way of example only, in which the first sliding slot 15 extends along the y direction.

In a specific implementation, as shown in fig. 2 and 3, the slider-crank mechanism 2 may be provided with a first motor 23, a slide block 22, and a push rod 21.

The specific operation process is that the first motor 23 rotates to drive the sliding block 22 to rotate, and the sliding block 22 rotates to drive the push rod 21 to move along the direction parallel to the first sliding groove 15, so that the push rod 21 moves towards the direction close to the first sliding groove 15 and extends into the first sliding groove 15 or moves towards the direction far away from the first sliding groove 15 and moves out of the first sliding groove 15.

Referring to fig. 2, 3 and 4, in a specific implementation, the push rod 21 is eccentrically disposed with respect to the slide block 22, a second slide slot 211 for sliding the slide block 22 is disposed on the push rod 21 at a position corresponding to the slide block 22, and the second slide slot 211 is perpendicular to the first slide slot 15. That is, the first motor 23 rotates to rotate the sliding block 22, and since the push rod 21 is eccentrically disposed with respect to the sliding block 22, and the sliding block 22 can slide along the second sliding groove 211 on the push rod 21, the rotation of the sliding block 22 is converted into the horizontal movement of the push rod 21. The first motor 23 may be specifically a stepping motor.

Referring to fig. 4 and 7, in a specific implementation, the push rod 21 has a connecting rod 212 and a moving rod 213, the moving rod 213 is perpendicular to the connecting rod 212, and the connecting rod 212 is formed with a second sliding slot 211. That is, the connecting rod 212 is slidable in the first sliding slot 15, so as to convert the rotation of the sliding block 222 into the horizontal movement of the moving rod 213, thereby driving the push rod 21 to slide into the first sliding slot 15 or slide out of the first sliding slot 15.

The second motor 31 may be specifically a stepping motor.

Illustratively, when the lifting fan lighting mechanism 4 needs to be lowered, the second motor 31 can rotate forward to drive the rope pulley 32 to rotate forward so as to release the traction piece 33 wound on the rope pulley 32, and the traction piece 33 is unfolded to lower the lifting fan lighting mechanism 4 connected with the traction piece 33; when the lifting fan lighting mechanism 4 needs to be lifted, the second motor 31 can rotate reversely, so that the rope wheel 32 is driven to rotate reversely, the traction piece 33 is wound on the rope wheel 32, and the lifting fan lighting mechanism 4 connected with the traction piece 33 is lifted after the traction piece 33 is wound and contracted.

In summary, the specific process of the fan lighting device of the embodiment is as follows: when landing cleaning is needed, the second motor 31 of the driving mechanism 3 and the first motor 23 of the slider-crank mechanism 2 are both started, at this time, the second motor 31 is in an energized state, that is, the second motor 31 is electrically connected with the power supply device 13, the second motor 31 can firstly rotate reversely, so that the rope pulley 32 is driven to rotate reversely to contract a part of the traction piece 33, and the traction piece 33 which pulls the lifting fan illuminating mechanism 4 is pre-tightened, so that when the first motor 23 drives the push rod 21 to move out of the first chute 15, the lifting fan illuminating mechanism 4 which is pulled by the traction piece 33 is prevented from being subjected to short-distance free falling at the moment due to the fact that the traction piece 33 is not pre-tightened, and further the lifting fan illuminating mechanism 4 is damaged. Meanwhile, the first motor 23 drives the crank sliding assembly 22 to rotate, so as to drive the push rod 21 to slide out of the first sliding groove 15 of the fixing mechanism 1 to a position where the lifting fan lighting mechanism 4 is not blocked from falling, i.e. the push rod 21 can slide out of the first sliding groove 15, at the moment, the second motor 31 rotates positively to drive the rope pulley 32 to rotate positively, so as to release the traction piece 33 wound on the rope pulley 32, and at the moment, the lifting fan lighting mechanism 4 connected to the free end of the traction piece 33 descends slowly. In the descending process, the electricity taking device 411 on the lifting fan lighting mechanism 4 and the electricity taking device 13 in the fixing mechanism 1 can be separated and powered off firstly, and then the lifting fan lighting mechanism 4 is driven by the driving mechanism 3 to descend to the height at which a user can conveniently clean, so that the user can conveniently and comprehensively clean dust deposited on the lifting fan lighting mechanism 4.

When the cleaning is completed, the second motor 31 of the driving mechanism 3 rotates reversely and drives the rope wheel 32 to rotate reversely, at this time, the traction piece 33 is gradually wound on the rope wheel 32, thereby driving the lifting fan lighting mechanism 4 to slowly rise, and rising the lifting fan lighting mechanism 4 to a position slightly higher than the original hanging position, so that the push rod 21 and the bottom of the electricity-getting device 411 of the lifting fan lighting mechanism 4 have a certain gap, so as to facilitate the rapid and accurate movement of the push rod 21 into the first slide slot 15 of the fixing mechanism 1, at which time the second motor 31 of the driving mechanism 3 stops rotating but remains electrically connected to the power supply device 13, namely, the power-on state is kept to keep the suspension height of the lifting fan lighting mechanism 4, at this time, the power supply device 13 supplies power to the first motor 23 of the slider-crank mechanism 2, the first motor 23 rotates and drives the sliding block 22 to rotate so as to move the push rod 21 into the first sliding slot 15, so that the push rod 21 can be supported at the bottom of the power-taking device 411; then, the second motor 31 is rotated forward to drop the lifting fan lighting mechanism 4 to a certain height and then hang the lifting fan lighting mechanism 4 on the push rod 21, so as to fix the lifting fan lighting mechanism 4 on the fixing mechanism 1 again and maintain the lifting fan lighting mechanism above the preset hanging position for subsequent lighting and/or blowing.
