Abstract
A rodent repeller having an elongated body, an end cap, an apex, a power supply, a buzzer, and a buzzer transformer. Connection of the power supply to the audible signal generator via the audible signal generator transformer produces a signal in the form of a chatter sound that mimics a frightened rodent to discourage rodents from remaining in a vicinity of the rodent repeller. The audible signal can be amplified with perforations in the apex, a tympanic resonator in the elongated body, or both. The rodent repeller can further utilize solar power.
Claims23
A rodent repeller for insertion into the ground, comprising:
- (a) an elongated body having an inserted end, an upper end, and an outside diameter, the upper end having threads, the elongated body being a cylinder, the inserted end comprising a tympanic resonator;
- (b) an end cap threaded to the upper end of the elongated body, the end cap comprising a T-handle, the T-handle having two protrusions that emerge perpendicular to a main part of the end cap;
- (c) an apex at the inserted end of the elongated body, the apex being a cone having a base diameter generally equivalent to the outside diameter of the elongated body, the apex having a second diameter that is smaller than the base diameter such that the apex tapers from the base diameter to the second diameter, the apex having a plurality of perforations;
- (d) a power supply, the power supply comprising a battery and a photovoltaic cell;
- (e) an audible signal generator, the audible signal generator being a resonant reed sounder, wherein the sound produced is a chattering sound that mimics the sound of distressed or frightened rodents;
- (f) an audible signal generator transformer to control power to the audible signal generator;
- (g) an LED, the LED having a brightness;
- and
- (h) an LED transformer, the LED transformer controlling an amount of power to the LED such that there is a generally 3:1 ratio between the brightness of the LED at an amount of power of about 6 volts and the brightness of the LED at an amount of power of about 2.5 volts;
- (i) wherein connection of the power supply to the audible signal generator, via the audible signal generator transformer, produces an audible signal to discourage rodents from remaining in a vicinity of the rodent repeller;
- and wherein connection of the power supply to the LED, via the LED transformer, produces a relative visual indicator, by brightness, that the rodent repeller is operable.
