Preferably, the fan base assembly further includes a catch 44 disposed on the housing 40 to further facilitate removal and installation by the user.

The installation process of the fan base assembly in this embodiment is described below with reference to fig. 1 to 13:

the upper cover 10 is provided with a power-off switch 20 assembling groove 11 which is distributed at the left side position of the upper cover 10 relative to the assembling, the screw hole 22 of the power-off switch 20 is aligned to the screw column of the upper cover 10, and the power-off switch 20 is fixed on the upper cover 10 through screws. The structure of the power-off switch 20 uses a plurality of power-off switches 20 in common, and the assembly method is consistent. When the upper cover 10 is pre-assembled with the two power-off switches 20. Which forms an assembly.

Assembling the upper cover 10 and the power-off switch 20 assembly to the base; one buckle 12 is respectively distributed on the front and the back of the upper cover 10, one buckle hole 32 is respectively distributed on the front and the back of the base, the buckle 12 of the upper cover 10 is buckled on the buckle hole 32 of the base during assembly, and the power-off switch 20 is fixedly assembled. One contact hole 31 is respectively distributed at the front and the rear of the base, and the contact piece 21 of the assembled power-off switch 20 is positioned in the range of the contact hole 31 of the base.

The power-on and power-off of the power-off switch 20 is achieved by mounting and dismounting the housing 40. The specific implementation method of the installation process of the shell 40 comprises the following steps: the top of base distributes has first unilateral buckle 33 four, and the position of assembling casing 40 around respectively distributes a pair ofly, and the direction that this pair of unilateral was opened the knot is carried on the back to the back, and the intermediate position still respectively distributes a pair of first bilateral buckle 34 around the top of base, and the orientation of its buckle 12 one end is relative direction. And the bottom of base only distributes and has first unilateral buckle 33 four, and its direction and position are unanimous with the first unilateral buckle 33 on top, and the bottom of base does not have the first bilateral buckle 34 structure on top. A pair of second single-side buckles 41 are respectively distributed on two sides of the top end and the lower end of the shell 40, the direction of each pair of buckles 12 is opposite, a second double-side buckle 42 is further distributed in the middle of the top end of the shell 40, and the triggering ribs 43 are distributed at the left position of the top end of the shell 40. When the shell 40 is assembled, the top end position of the shell 40 is horizontally aligned to the top end position of the base, then the shell is horizontally pushed inwards along the radial direction for assembly, when the shell is assembled in place, the second single-side buckle 41 at the top end and the top end of the shell 40 is buckled on the first single-side buckle 33 at the top end and the top end of the base, and the second double-side buckle 42 at the top end is buckled on the first double-side buckle 34 at the top end of the base.

When the shell 40 is assembled, the triggering ribs 43 on the shell 40 are aligned to the contact holes 31 positioned on the base, when the shell 40 is horizontally pushed inwards for assembly, the triggering ribs 43 contact the contacts 21 of the power-off switch 20 and horizontally push the contacts 21 inwards, the displacement stroke of the contacts 21 in the horizontal pushing process reaches the power-on range of the power-off switch 20, and when the shell 40 is assembled, the contacts 21 are horizontally pushed into a horizontal state by the triggering ribs 43. The trigger rib 43 is against the contact 21.

When the product is electrified, the front shell 40 and the rear shell 40 are installed in place, and the power-off switches 20 on the two sides are respectively triggered. When the shell 40 is to be disassembled, the operation is also simple, and after the front and rear shells 40 are assembled, two handle positions 44 are distributed at the upper end position of the shell 40, and the two handle positions are respectively arranged at the left and the right and have the same shape and size. The assembled two housing 40 snap locations 44 form a ring-shaped snap location at the top of their base, again one on each side of the base. When the shell is disassembled, the annular buckle position is buckled by two hands, and the shell 40 can be disassembled outwards by applying light force.

Because the frequency of casing 40 dismantlement and installation is more in the use, for guaranteeing that the long-term effectiveness of casing 40 use, through the dynamics of simulation analysis simulation casing 40 in the dismantlement and the installation, optimize the buckle structural design of casing 40, design 4N with every second unilateral buckle 41 of casing 40 and every first unilateral buckle 33 of base dismantlement dynamics, the second bilateral buckle 42 in the middle of casing 40 and the first bilateral buckle 34 of base dismantlement dynamics are designed 2.5N, make the dynamics of whole casing 40 dismantlement 20.5N, the best dismantlement that the dynamics control of unilateral knot hand position 44 of casing 40 is about 10N is felt.

By utilizing the structure of the power-off switch 20 in the embodiment, after any shell 40 of the product is detached in use, power-off protection is provided, so that the safety of the product is greatly improved, and the product tends to humanized design.

The present embodiment further provides a bladeless fan, including the fan base assembly as described above, and further the advantages of the fan base assembly in this embodiment, the bladeless fan in this embodiment should also have, and therefore, the details are not repeated herein.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
