[0002] A circulating fan is a device used to promote the circulation of air or gas, achieving air flow in an indoor or enclosed space by continuously transporting air from one area to another. The application of circulating fans is very wide, covering various occasions from household to industrial use.

[0003] The basic function of a circulating fan is to move air through the centrifugal force or axial thrust generated by the rotation of the impeller (or fan blade). However, during long-term use, a lot of dust accumulates on the surface of the fan blade. The front and rear protective nets of traditional circulating fans are usually fixed by screws and nuts, and the connection between the fan blade and the motor usually adopts threaded connection or the fan blade is fixed to a hole-end shaft by bolts. Such design is more troublesome during maintenance and cleaning, and tools are needed to assist in disassembly. SUMMARY

[0009] Further illustrate, the card board side towards the protective net is equipped with inclined plane, the inclined plane is contacted and matched with the protective net, and the card board is matched with the corresponding protective net.

[0010] Further illustrate, it further includes screw rod and movable block, screw rod is connected in the middle of fixed frame, movable block is connected on the outside of screw rod, and the inside of screw rod is resisted to the two card boards on the same side.

CONCRETE IMPLEMENTING METHOD

[0018] The utility model will be further described in connection with specific embodiment, and the illustrative embodiment of this utility model and the explanation used to explain the utility model, but it is not as the limitation of the utility model.

[0019] Embodiment: a circulating fan with dismounting mechanism, like Figures 1-4As shown, including the base 1, cylinder 2, frame 3, motor 4, rotating shaft 5, fan 6, protective net 11, locking assembly and clamping assembly, the base 1 top connected with cylinder 2, cylinder 2 installed in the frame 3, frame 3 is installed in the motor 4 through the bolt, the motor 4 output shaft connected with rotating shaft 5, rotating shaft 5 on the clamping fan 6, rotating shaft 5 front part up and down cutting plane, the fan 6 clamping in the plane, cylinder 2 inside front and back symmetrically clamping for dustproof protective net 11, two protective net 11 located in the fan 6 front and back side, rotating shaft 5 is equipped with locking assembly, cylinder 2 is equipped with clamping assembly.

[0020] As shown in Figures 2-3 The locking assembly includes rotating block 7, connecting rod 8 and first spring 9, rotating shaft 5 front part left and right sides are provided with screw groove 51, screw groove 51 between threaded connection has rotating block 7, rotating block 7 on the sliding type connecting rod 8 is U-shaped, connecting rod 8 left and right sides and rotating block 7 are all connected with first spring 9, connecting rod 8 both ends and fan 6 sliding insertion, in turn, stable fan 6, rotating block 7 is located in the fan 6 front side.

[0021] As shown in Figure 1 And Figure 4 The clamping assembly includes fixed frame 10, clamping plate 12, pull handle 121, second spring 13, screw rod 14 and movable block 15, cylinder 2 left and right sides are all welded with fixed frame 10, fixed frame 10 inside are all front and back symmetrically sliding type connected with clamping plate 12, clamping plate 12 and fixed frame 10 inside are all connected with two second spring 13, clamping plate 12 outside are all welded with pull handle 121, pull handle 121 and fixed frame 10 slidingly connected, clamping plate 12 on the side towards the protective net 11 are all provided with inclined plane, the inclined plane and the protective net 11 contact fit, clamping plate 12 and the corresponding protective net 11 clamping fit, fixed frame 10 middle part are all screw connected with screw rod 14, screw rod 14 outside are all connected with movable block 15, screw rod 14 inside rest against the two clamping plate 12 on the same side, to avoid its movement.

[0022] The device can be installed in a factory or other application center requiring a ventilation system. By starting the motor 4, the rotating shaft 5 is driven to rotate, thereby driving the fan blade 6 to rotate, completing the blowing or air extraction operation. The protective nets 11 arranged in front and back play a protective role to prevent external debris from entering the cylinder 2. When the device needs to be maintained, in the initial state, the clamping plate 12 clamps the protective net 11. If the protective net 11 needs to be removed, first rotate the movable block 15 to drive the screw rod 14 to rotate, so that the screw rod 14 moves outward and no longer abuts against the clamping plate 12. At this time, the pull handle 121 can be pulled outward to drive the clamping plate 12 to move outward, and the second spring 13 is compressed. After the clamping plate 12 moves outward, it no longer clamps the protective net 11, and the protective net 11 can be removed from the cylinder 2. Then, the pull handle 121 is released, and the second spring 13 is rebounded to reset, so that the clamping plate 12 and the pull handle 121 move inward and reset. Next, the fan blade 6 is removed. When operating, first pull the connecting rod 8 forward to compress the first spring 9. After the connecting rod 8 and the fan blade 6 are disconnected, the connecting rod 8 can be rotated to drive the rotating block 7 to rotate, so that the rotating block 7 is unscrewed from the threaded groove 51. Then, the first spring 9 is rebounded to reset, the rotating block 7 is released from the fixation of the fan blade 6, and the fan blade 6 can be removed from the rotating shaft 5. After maintenance is completed, when the fan blade 6 is installed, the fan blade 6 is sleeved on the rotating shaft 5, and then the rotating block 7 is screwed along the threaded groove 51. During this operation, the connecting rod 8 needs to remain in a state of not being inserted with the fan blade 6, and the first spring 9 is in a compressed state. After the rotating block 7 is screwed tightly along the threaded groove 51, the connecting rod 8 is aligned with the fan blade 6. The connecting rod 8 is released, the first spring 9 is rebounded to reset, the connecting rod 8 is rebounded to the rear side and clamped into the fan blade 6, thereby completing the fixation of the fan blade 6. Then, the protective net 11 is clamped into the cylinder 2 in front and back. The protective net 11 contacts the inclined surface of the clamping plate 12, drives the clamping plate 12 and the pull handle 121 to move outward, and the second spring 13 is compressed. After passing the inclined surface, the second spring 13 is rebounded to reset, the clamping plate 12 and the pull handle 121 are reset, and the clamping plate 12 clamps both sides of the protective net 11, thereby completing the fixation of the protective net 11. Finally, the movable block 15 is reversed to drive the screw rod 14 to move inward and abut against the clamping plate 12, thereby fixing the clamping plate 12.

[0023] Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
