Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

Referring to fig. 1-4, the utility model discloses a battery pack powered fan, comprising a base assembly, wherein the base assembly is arranged at the lower end of the fan and is used for supporting the fan, and the base assembly comprises:

the base upper cover 300 is provided with a first connecting terminal, and the base upper cover 300 is provided with a limit notch 310;

the battery pack 400 can slide along a first direction relative to the base upper cover 300, the battery pack 400 is provided with a locking block 410, and the locking block 410 can slide along a second direction relative to the battery pack 400 to extend into or withdraw from the limit notch 310 so as to lock or unlock the sliding of the battery pack 400 relative to the base upper cover 300; the battery pack 400 is further provided with a second connection terminal, and the battery pack 400 slides along a first direction relative to the base upper cover 300, so that the second connection terminal is connected to or separated from the first connection terminal.

Specifically, the present application provides the battery pack 400 at the lower end of the entire fan to support the fan, replacing the original base, and eliminating the costs of separately designing and manufacturing the base.

Meanwhile, a locking block 410 sliding along the second direction is arranged on the battery pack 400, and a limiting notch 310 is arranged on the base upper cover 300; the locking block 410 slides along the second direction to enable the locking block to extend into or withdraw from the limiting notch 310, so that the battery pack 400 is locked or unlocked to slide along the first direction relative to the base upper cover 300, connection and separation of the battery pack 400 and the base upper cover 300 are achieved, and the battery pack 400 is quickly installed and removed.

The first connecting terminal is arranged on the base upper cover 300, the second connecting terminal is arranged on the battery pack 400, and when the battery pack 400 slides to the position where the locking block 410 can go deep into the limiting notch 310 relative to the base upper cover 300, the first connecting terminal is connected with the second connecting terminal, so that the battery pack 400 supplies power to the fan.

Further, the first direction is perpendicular to the second direction.

Specifically, the first direction and the second direction are perpendicular, and when the locking block 410 slides in the second direction to unlock or lock the battery pack 400, the position of the battery pack 400 with respect to the base upper cover 300 in the first direction is not changed. That is, the movement of the battery pack 400 with respect to the base upper cover 300 and the movement of the locking block 410 with respect to the limit notch 310 do not interfere with each other.

Further, the battery pack 400 is further provided with a button 440 connected to the locking block 410, and the button 440 is pressed to enable the locking block 410 to extend into or withdraw from the limiting notch 310.

Specifically, pressing the button 440 can simultaneously drive the locking block 410 to move along the second direction, i.e. to extend into or withdraw from the limiting notch 310, so as to lock and unlock the battery pack 400.

Still further, a return spring is further disposed on the button 440, and when the button 440 is pressed, the return spring is compressed, and after the button 440 is released, the locking block 410 can be driven to extend into the limiting notch 310 under the action of the elastic force of the return spring, so as to realize automatic locking of the battery pack 400.

Further, the battery pack 400 has an insertion end at which the second connection terminal is disposed and an unlocking end at which the locking block 410 is disposed, the locking block being Jie Suoduan;

the locking block 410 has a first end face toward the insertion end and a second end face at the back of the first end face, the first end face being gradually inclined toward the second end face in a direction toward the base upper cover 300 to form a first guide face 411.

The first guide surface 411 is provided on the locking piece 410, and when the battery pack 400 slides in the direction toward the insertion end, the first guide surface 411 first contacts the base upper cover 300, and as the battery pack 400 continues to slide, the first guide surface 411 slides relatively to the base upper cover 300, the base upper cover 300 presses the first guide surface 411, and the locking piece 410 is urged to move downward by a certain position (compressing the return spring); as the battery pack 400 continues to slide until the locking block 410 is below the limiting notch 310, the return spring releases and drives the locking block 410 to extend upward into the limiting notch 310, thereby achieving locking.

It can be seen that the first guide surface 411 can substantially smooth the friction of the locking block 410 against the base upper cover 300, and at the same time, the base upper cover 300 presses the locking block 410, compresses the return spring to store the force, and finally, the automatic locking of the locking block 410 can be realized when releasing. That is, when the battery pack 400 is mounted, the first guide surface 411 and the base upper cover 300 are rubbed against each other, driving the locking block 410 to move downward without manually pressing the button 440.

Further, a second guiding surface 320 is provided at an end of the base upper cover 300 near the unlocking end, and the second guiding surface 320 is gradually inclined inward from the direction toward the battery pack 400.

Similarly, the base upper cover 300 is provided with the second guide surface 320, and when the battery pack 400 is mounted, the first guide surface 411 abuts against the second guide surface 320, and the battery pack 400 is mounted more smoothly by sliding relatively, so that jamming is avoided.

Further, the limiting notch 310 includes a plurality of side surfaces and a first inclined surface 340, and the locking block 410 extends into the limiting notch 310 to make the first guiding surface 411 fit with the first inclined surface 340.

The first guide surface 411 is attached to the first inclined surface 340, so that the contact area between the locking block 410 and the limiting notch 310 is increased, and the locking strength is improved.

Further, the battery pack 400 is provided with a first sliding groove 450 along the second direction, the locking block 410 is provided with a guide post 430, and the guide post 430 is slidably disposed in the first sliding groove 450.

Further, the base upper cover 300 is provided with a guide bar 330, the battery pack 400 is provided with a second sliding groove 420 along the first direction, and the guide bar 330 can slide along the second sliding groove 420.

Further, the air blower assembly 100 further comprises a grab handle 200, wherein one end of the grab handle 200 is connected with the air blower assembly 100, and the other end is connected with the base upper cover 300.

Further, the blower assembly 100 may rotate in a vertical plane relative to the grip 200.

The blowing assembly 100 rotates in a vertical plane, and the blowing angle and the height can be adjusted.
