Abstract

Disclosed are embodiments of a pest repellent device and methods of operating the pest repellent device. The device can comprise a device body having a first body end and a second body end, a blade motor housed within the device body, a rotatable component disposed at the first body end, one or more fan blades coupled to the rotatable component, and a foldable base assembly coupled to the second body end. The rotatable component can be rotated by the blade motor. The foldable base assembly can comprise at least three supporting legs with each of the supporting legs shaped as an elongated parabolic cylinder. The pest repellent device can have a folded configuration where the at least three supporting legs surround and partly encircle the device body and an unfolded configuration where the supporting legs are positioned at an angle with respect to a longitudinal axis of the device body.

Claims (28)

1. A pest repellent device, comprising:

a device body having a first body end, a second body end, and a magnetic ring configured to fit over an upper segment of the device body;

a blade motor housed at least partially within the device body;

a rotatable component disposed at the first body end, wherein the rotatable component is configured to be rotated by the blade motor;

one or more fan blades coupled to the rotatable component; and

a foldable base assembly coupled to the second body end, wherein the foldable base assembly comprises three supporting legs, wherein each of the supporting legs is shaped as an elongated parabolic cylinder,

wherein the pest repellent device has a folded configuration and an unfolded configuration, wherein the three supporting legs are configured to surround and partly encircle the device body when the pest repellent device is in the folded configuration, and wherein the three supporting legs are configured to fold radially and pivotally outward and then pivotally downward with respect to a longitudinal axis of the device body until each of the supporting legs is positioned at an angle with respect to the longitudinal axis of the device body when the pest repellent device is in the unfolded configuration,

wherein each of the supporting legs further comprises a ferromagnetic metal piece coupled to a distal end of the supporting leg, wherein the ferromagnetic metal piece is configured to magnetically attach to the magnetic ring when the pest repellent device is in the folded configuration, and

wherein the one or more fan blades are configured to hang downward when the pest repellent device is in the folded configuration, and wherein one or more of the supporting legs is configured to at least partially encase one of the fan blades such that at least part of the fan blade is positioned in between an exterior surface of the device body and the one or more supporting legs when the pest repellent device is in the folded configuration.

2. The pest repellent device of claim 1 , further comprising a clip assembly comprising a top clip and a bottom clip configured to clip onto a proximal end of one of the fan blades, wherein the rotatable component further comprises at least one snap clamp, wherein at least part of the clip assembly is configured to snap into the snap clamp and allow the fan blade to pivot with respect to the device body.

3. The pest repellent device of claim 1 , further comprising an activator button extending from the second body end of the device body, wherein the activator button is configured to activate the blade motor to rotate or spin the one or more fan blades.

4. The pest repellent device of claim 1 , wherein at least one of the fan blades is made of a flexible polymeric material.

5. The pest repellent device of claim 1 , wherein at least a portion of the device body serves as a battery bin to receive and house a plurality of batteries to power the blade motor.

6. The pest repellent device of claim 1 , further comprising a device base configured to be coupled to the second body end of the device body, wherein each of the supporting legs is coupled to the device base via a hinge connector.

7. The pest repellent device of claim 1 , wherein the device body is shaped as an elongated cylinder.

8. A method of using a pest repellent device, comprising:

unfolding at least three supporting legs of the pest repellent device radially and pivotally outward and then pivotally downward with respect to a longitudinal axis of a device body of the pest repellent device until each of the supporting legs is positioned at an angle with respect to the longitudinal axis of the device body, wherein each of the supporting legs is shaped as an elongated parabolic cylinder, and wherein the pest repellent device further comprises:

a blade motor housed at least partially within the device body,

an activator button extending from the device body and configured to activate the blade motor,

a rotatable component disposed at a first body end of the device body, wherein the rotatable component is configured to be rotated by the blade motor, and

one or more fan blades coupled to the rotatable component;

pressing the activator button to activate the blade motor and rotate the fan blades; and folding at least one of the fan blades vertically downwards toward the device body such that the fan blade is positioned in between an exterior surface of the device body and the one or more supporting legs when the pest repellent device is in a folded configuration.

9. The method of claim 8 , further comprising folding the at least three supporting legs vertically upward such that the at least three supporting legs surround and partly encircle the device body to cause the pest repellent device to attain the folded configuration.

10. The method of claim 9 , wherein the pest repellent device further comprises a magnetic ring configured to fit over an upper segment of the device body, wherein each of the supporting legs further comprises a ferromagnetic metal piece coupled to a distal end of the supporting leg, wherein folding the at least three supporting legs vertically upward brings the ferromagnetic metal piece into contact with the magnetic ring to magnetically attach the ferromagnetic metal piece to the magnetic ring to prevent the supporting legs from unfolding when the pest repellent device is in the folded configuration.

11. The method of claim 9 , wherein at least one of the fan blades is made of a flexible polymeric material.

12. The method of claim 9 , wherein at least a portion of the device body serves as a battery bin to receive and house a plurality of batteries to power the blade motor.

13. The method of claim 9 , further comprising a device base configured to be coupled to the device body, wherein each of the supporting legs is coupled to the device base via a hinge connector.

14. The method of claim 9 , wherein the device body is shaped as an elongated cylinder.
