Abstract
An improved mole chaser includes a rotation block eccentrically mounted on a motor spindle. The rotation block includes a loosely held impact ring which may hit an impact member housed in the battery chamber when motor rotates to generate an audio vibration frequency. The eccentrically rotation of the rotation block will generate another and additional audio vibration frequency to augment the moles and other underground burrowing rodents chasing effect.
Claims5
An improved mole chaser, comprising:
- a tubular main stem having an open end with external screw threads formed thereon;
- a cap having internal screw threads formed therein for engaging with the external screw threads of the main stem;
- a battery chamber housed in the main stem having a tubular front section, a separating wall located at a rear end of the front section and a trough located behind the separating wall, the tubular front section containing an impact member which has a plurality of bulges formed on an inside wall thereof;
- a rotation vibrating means including a motor mounted on one side of the separating wall and a rotation block located within the impact member, the rotation block including a base eccentrically engaged with a spindle of the motor, a lid spaced from and coupled with the base and being eccentrically engaged with the spindle, an impact ring loosely held between the base and the lid;
- and
- a control circuit board located in the trough to control the motor rotation;
- wherein the motor rotation drives the impact ring hitting the bulges to generate an audio vibration frequency and also hitting the base and the lid to rotate eccentrically to generate another audio vibration frequency for forming a multi-frequency vibration.
