Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

The invention provides a swing type electric hand fan, as shown in fig. 1 to 4, which comprises a hand fan body 1 and a swing handle 2, wherein a power driving part 3 for providing power, a swing conversion part 4 for converting the rotation action of the power driving part 3 into the swing action and a fan body clamp 5 for fixing the hand fan body 1 are arranged in the swing handle 2, the lower end of the swing conversion part 4 is in power transmission connection with a power output shaft of the power driving part 3, a swing fulcrum 401 is fixedly arranged at the middle part of the swing conversion part, and the upper end of the swing conversion part is fixedly arranged with the fan body clamp 5;

as shown in fig. 3, the power driving component 3 has an eccentric power output shaft 31, the lower end of the swing conversion component 4 is provided with a swing groove 41, the extension line of the length direction of the notch of the swing groove 41 is parallel to the fan surface of the hand fan body 1, and the eccentric power output shaft 31 is movably arranged in the swing groove 41 in a matching manner and drives the lower end of the swing conversion component 4 to swing back and forth around the swing fulcrum 401 thereof.

The invention designs a matching structure between an eccentric power output shaft 31 and a swing groove 41 in a swing handle 2, the power driving part 3 is enabled to output the rotation action in the circumferential direction by arranging the eccentric power output shaft 31, and because the extension line of the length direction of the notch of the swing groove 41 is arranged in parallel with the sector surface of the hand fan body 1, the allowance space in the length direction of the swing groove 41 offsets the displacement action in the left and right directions relative to the hand fan body 1 when the eccentric power output shaft 31 does the circumferential rotation action, and only the swing in the front and back directions relative to the hand fan body 1 is left, thereby simulating the action of manually swinging the fan.

In addition, according to the action coordination of the eccentric power output shaft 31 and the swing groove 41, when the eccentric power output shaft 31 rotates to the stroke end point perpendicular to the fan surface direction, the swing displacement rate of the swing conversion component 4 in the front and back direction is gradually reduced to stop and generate steering, so that the buffer action generated when the manual swing fan steers can be simulated more truly.

Specifically, as shown in fig. 3 and 4, the power output end of the eccentric power output shaft 31 is vertically inserted into the notch of the swing conversion component 4 and is movably matched with the notch, the width of the notch of the swing groove 41 is matched with the eccentric power output shaft 31, the width of the groove is gradually increased from the notch to the bottom of the groove, and specifically, the expansion angle of the groove relative to the notch is greater than the swing angle of the eccentric power output shaft 31 driving the swing conversion component 4.

In order to facilitate the eccentric power output shaft 31 to freely move in the left and right directions relative to the hand fan body 1 in the notch, as shown in fig. 4, a slide rail 42 is arranged in the notch of the swing groove 41 along the length direction of the notch, and the power transmission end of the eccentric power output shaft 31 is movably arranged in the swing groove 41 through a slide block 43, so that the power output end of the eccentric power output shaft 31 freely moves in the left and right directions relative to the hand fan body 1 in the notch, and further, the displacement action in the left and right directions relative to the hand fan body 1 when the eccentric power output shaft 31 performs the circumferential rotation action is counteracted.

Meanwhile, when the eccentric power output shaft 31 performs a circumferential rotation action, the eccentric power output shaft itself also performs an axial rotation action with respect to the notch, so as shown in fig. 4, a bearing 44 is sleeved on the power transmission end of the eccentric power output shaft 31, and an outer ring of the bearing 44 is fixedly connected with the slider 43, thereby eliminating the axial rotation action of the eccentric power output shaft 31 itself with respect to the notch.

After the power is counteracted, the power transmitted to the swing conversion component 4 by the eccentric power output shaft 31 only remains the front and back swing power relative to the hand fan body 1, namely the action of manually swinging the fan can be simulated; when the eccentric power output shaft 31 rotates to the stroke end point perpendicular to the fan surface direction, the swing displacement rate of the swing conversion component 4 in the front and back direction is gradually reduced to stop and turn, and then the buffering action generated when the manual swing fan turns is simulated more truly, so that the wind power is softer, and the body feeling is better.

As shown in fig. 1 and fig. 2, the sector clamp 5 has a jaw opening from top to bottom, the handle of the hand fan body 1 is fixedly disposed on the sector clamp 5 by falling into the jaw opening, the sector clamp 5 is fixedly disposed on the upper end of the swing conversion component 4 by a fastening component, specifically, the lower end of the sector clamp 5 is provided with a fastener, the upper end of the swing conversion component 4 is provided with a clamping groove, the clamping groove is disposed in cooperation with the fastener of the sector clamp 5, the notch setting direction of the clamping groove on the sector clamp 5 is perpendicular to the notch setting direction of the swing groove 41 of the swing conversion component 4, that is, the plane of the sector of the hand fan body 1 is parallel to the extension line of the notch length direction of the swing groove 41. Meanwhile, the central axis of the swing conversion part 4 is parallel to the central axis of the fan handle of the hand fan body 1, so that when the swing conversion part 4 is driven by the power driving part 3 to swing back and forth, the hand fan body 1 can be driven to swing back and forth. Preferably, the fan body clamp 5 comprises a cattail-shaped clamp and a folding fan-shaped clamp.

In order to fix the swing type electric hand fan at different positions, as shown in fig. 1 and fig. 2, the swing type hand fan further comprises a universal clamp 6, the universal clamp 6 comprises a sleeve part 61 which is matched with the swing handle 2 in diameter, a clamping jaw part 62, and a universal rotating part 63 is arranged between the clamping jaw part 62 and the sleeve part 61. The swing type electric hand fan is arranged on the universal clamp 6 through the sleeving part 61, then is fixed on a position which needs to be fixed by a user through the clamping jaw part 62, and can also adjust the setting angle of the swing type electric hand fan through the universal rotating part 63, so that the swing type electric hand fan can be flexibly applied.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
