Abstract
The present invention relates to a vibration motor having a through hole formed in a rotor, in which: a rotor that penetrates and is coupled to a motor housing and a vibrating part plays a role of receiving a cleaning solvent and at the same time acts as a vibration transmission medium, and thus, no separate supply pipe is required, thereby contributing to cost reduction and productivity improvement; simplification of an internal structure assists in improving performance; a nozzle is detachably fixed to a front end of the rotor, and thus, various types of nozzles can be selectively replaced according to an object to be cleaned; and an object to be cleaned can be effectively washed by supplying various cleaning solvents such as water, oil, powder, and air to the through hole in the rotor.
Claims8
A vibration motor having a through hole formed in a rotor, the vibration motor comprising:
- a motor housing;
- a vibrating part coupled to opposite inner sides of the motor housing and providing vibration while rotating the rotor in forward and reverse directions;
- the rotor having a predetermined length, having the through hole formed therein, and coupled to an inner central portion of the motor housing;
- a nozzle detachably coupled to a front side of the rotor;
- a coupling part fixing the rotor to the nozzle;
- bearings coupled to the rotor inside the motor housing and guiding rotation of the rotor;
- and
- front and rear covers coupled to front and rear sides of the motor housing,
- wherein the motor housing comprises:
- a body portion;
- a mounting hole formed through an inner central portion of the body portion;
- a coupling space formed at each of opposite sides of an inside of the body portion around the mounting hole to allow the vibrating part to be coupled thereto;
- and
- a coupling hole formed at each of upper and lower portions of a rear end of the body portion to allow the rear cover to be coupled thereto.
