Further, a through hole 520 is formed in the limiting member 500, and the winding member 420 penetrates through the through hole 520. Specifically, the through hole 520 and the seventh dismounting hole 422 are located in the same plane, one end of the winding member 420 connected to the limiting member 500 penetrates through the through hole 520 and then is bent and stacked on the limiting member 500, and then is connected to the limiting member 500 and the lifting member 200 through the fourth dismounting member 600. Through the arrangement of the via hole 520, the installation path of the winding member 420 on the limiting member 500 is more complex, so that the winding member 420 and the limiting member 500 can be prevented from loosening in the connection process, and the stability of installation between the winding member 420 and the limiting member 500 and between the winding member and the lifting member 200 can be effectively improved. In addition, when the fourth dismounting member 600 is used to mount the limiting member 500, the winding member 420 and the lifting member 200, the hole wall of the through hole 520 can also position and limit the winding member 420, so as to prevent the winding member 420 from falling off from the limiting member 500.

In an embodiment, the lifting member 200 is clamped to the limiting member 500, so as to further improve the stability of the installation of the lifting member 200 and the limiting member 500. Specifically, the lifting member 200 has a ninth engaging portion 240, the limiting member 500 has a tenth engaging portion 530, and the ninth engaging portion 240 and the tenth engaging portion 530 are engaged with each other.

Alternatively, the first guide part 150 may be any one of a guide groove and a guide protrusion, and the second guide part 540 may be the other one of the guide groove and the guide protrusion. In one embodiment, the first guiding portion 150 is a guiding protrusion protruding from the inner wall of the supporting body 110, and the second guiding portion 540 is a guiding through groove. Thus, the weight of the stopper 500 can be reduced, and the stopper 500 and the lifting member 200 can be lifted more flexibly. At the same time, the load on the driver 410 is reduced.

Specifically, the first guide portions 150 are plural, the plural first guide portions 150 are arranged at intervals along the circumferential direction of the supporting main body 110, the plural second guide portions 540 are plural, the plural second guide portions 540 are arranged at intervals along the circumferential direction of the limiting member 500, and the plural first guide portions 150 are matched with the plural second guide portions 540 in a one-to-one correspondence manner. The stability of the lifting member 200 can be further improved by providing a plurality of first guide members and a plurality of second guide members.

In an embodiment, the supporting member 100 has a first position-limiting portion, and the lifting member 200 drives the position-limiting member 500 to ascend until the position-limiting member 500 abuts against the first position-limiting portion, at this time, the lifting member 200 is located at a limit position slidable along the ascending direction, the speed of the lifting member 200 returns to zero, and the lifting member 200 can be prevented from sliding out of the supporting body 110 due to the continuous sliding of the lifting member 200. Specifically, the first position-limiting portion may protrude from a protrusion on the inner wall of the supporting body 110, and the projection of the first position-limiting portion and the position-limiting member 500 on the surface of the bottom cover 130 facing the top cover 120 at least partially overlaps.

In an embodiment, when the first retaining portion 112 is a protrusion and the second retaining portion 123 is a slot, the first position-limiting portion is the first retaining portion 112, the first retaining portion 112 partially extends into the second retaining portion 123, the position-limiting member 500 has a guide unit 550 extending along the lifting direction of the lifting member 200, and the guide unit 550 is aligned with a portion of the first retaining portion 112 that does not extend into the second retaining portion 123. The guide unit 550 is formed with a second guide part 540, and the limiting member 500 is driven by the winding member 420 to gradually rise until the end of the guide unit 550 opposite to the bottom cover 130 abuts against the end of the second retaining part 123 facing the bottom cover 130, and the lifting member 200 stops descending.

Next, the assembly process of the entire fan 10 is explained by specifically describing.

First, the sixth clamping portion 441 of the first direction-changing wheel 440 is clamped with the first arc-shaped groove 1132 of the support main body 110, then the winding member 420 is wound around the first direction-changing wheel 440, the mounting plate 122, the abutting plate 125 and the inner flange 127 of the top cover 120 extend into the receiving cavity 140, the second arc-shaped groove 126 of the abutting plate 125 is clamped with one side of the sixth clamping portion 441 far away from the bottom cover 130, meanwhile, the first clamping portion 112 is matched with the second clamping portion 123, and thus, the first direction-changing wheel 440 and the top cover 120 are completely mounted.

Next, the lifting member 200 is disposed through the top cover 120 and the supporting body 110, and the second limiting portion 210 of the lifting member 200 is abutted against a side of the top cover 120 opposite to the bottom cover 130, so as to achieve the initial positioning of the lifting member 200. Then, the first guide portion 150 of the supporting body 110 is engaged with the second guide portion 540 of the limiting member 500, the ninth retaining portion 240 of the lifting member 200 is engaged with the tenth retaining portion of the limiting member 500, and then one end of the winding member 420, which is far away from the driving member 410, passes through the through hole 520, and the fourth dismounting member 600 sequentially passes through the seventh dismounting hole 422, the eighth dismounting hole 510 and the ninth dismounting hole 230 to fix the limiting member 500, the lifting member 200 and the winding member 420.

Then, the eighth catch 451 of the second reversing wheel 450 cooperates with the seventh catch 133 of the bottom cover 130 to fix the second reversing wheel 450. Then, the rotating shaft 414 of the driving member 410 is inserted into the through hole 431 of the driving wheel 430, and the fourth catching portion 432 of the driving wheel 430 is engaged with the third catching portion 132 of the bottom cover 130 to connect the driving member 410 and the driving wheel 430. Then, the winding member 420 is wound around the surfaces of the second reversing wheel 450 and the driving wheel 430, and the driving wheel 430 and the winding member 420 are coupled using the third dismounting member 700. Then, the driving member 410 is connected to the bottom cover 130 by using the second detaching member, so that the driving member 410 can be fixed. Finally, the bottom cover 130 is covered on the opening of the bottom end of the support main 110, and the first disassembly member detachably connects the bottom cover 130 with the support main 110. The entire fan 10 is now completely installed.

When the fan 10 works, the rotating shaft 414 of the driving member 410 drives the driving wheel 430 to rotate along the first direction, the winding member 420 is continuously wound on the driving wheel 430, and meanwhile, the winding member 420 slides along the outer peripheries of the first direction-changing wheel 440 and the second direction-changing wheel 450, and under the action of the driving member 410, the winding member 420 exerts a pulling force on the lifting member 200, and the pulling force pulls the limiting member 500, the lifting member 200, and the air blowing member 300 to rise, so as to adjust the air blowing position of the air blowing member 300. Due to the cooperation of the first guide part 150 and the second guide part 540, the lifting member 200 can stably drive the air blowing member 300 to ascend in the lifting direction. When the limiting member 500 slides to abut against the first limiting portion, the lifting member 200, the limiting member 500, and the blowing member 300 move to the limit position capable of being lifted, and the lifting member 200, the limiting member 500, and the blowing member 300 stop sliding. When the rotating shaft 414 of the driving member 410 drives the driving wheel 430 to rotate along the second direction, the winding member 420 is unfolded, and the winding member 420 drives the limiting member 500, the lifting member 200 and the blowing member 300 to descend until the second limiting portion 210 of the lifting member 200 abuts against the supporting member 100. At this time, the lifting member 200, the limiting member 500, and the blowing member 300 move to the limit positions at which they can be lowered, and the lifting member 200, the limiting member 500, and the blowing member 300 stop sliding. To this end, the fan 10 performs one cycle of ascending and descending.

In the fan 10, the fan 10 is provided with the lifting member 200 and the winding assembly 400, the winding assembly 400 includes the driving member 410 and the winding member 420, the driving member 410 is controlled to drive the winding member 420 to drive the lifting member 200 to lift relative to the supporting member 100, compared with the prior art, the trouble of manual adjustment is eliminated, time and labor are saved, and the use is more convenient.
