Disclosed is a vacuum agitator for a dental technician. According to the present invention, the vacuum agitator includes: a main body that includes a magnetic sensor and a control means, which controls operation of an agitation motor and a vacuum pump by using a signal of the magnetic sensor; an agitation unit joining part which is penetrated by a driving shaft of the agitation motor, is joined with the driving shaft, and includes a suction hole connected to the vacuum pump formed thereon; and an agitation unit that includes an agitation container, a cover, which is joined with the top of the agitation container and includes a vent holes, an agitation shaft penetrating the cover, an agitation wing joined with the agitation shaft in the agitation container, and a magnet installed on a location corresponding to the magnetic sensor on an upper side of the cover. According to the present invention, the magnet sensor installed on the main body senses the magnet installed on the agitation unit to determine whether the agitation unit is joined or not. Therefore, decrease of vacuum suction efficiency caused by a through-hole formed on the agitation unit joining part can be prevented. Moreover, when a worker joins the agitation shaft with the driving shaft, the magnet sensor automatically senses the magnet. Therefore, the worker does not need to consider a location of the sensor. Consequently, convenience of use is increased when the agitation unit is joined. |
