Description

Moving type dust collector for grinding a false tooth}

The present invention relates to a dust collector, and more particularly, to a dental mobile dust collector that can easily store and use the denture polishing tool, while stably supporting the arm to precisely polish the denture.

Generally, dentures refer to dental prostheses that are artificially replaced when natural teeth and tissues associated with them are missing, such as dentures and implant teeth used in dentistry.

These, dentures are mostly pore in a dental laboratory, such as spread to each dental clinic, the dentist uses the dentures to treat and treat the patient's teeth.

On the other hand, dentures, because of the nature used to replace the teeth, as well as to evenly orthodontic treatment during the procedure to minimize the discomfort felt by the patient, requires more precise dimensional control. Therefore, in the dental laboratory, it is necessary to polish the dentures to increase the dimensional accuracy of the dentures, and the dental clinic also polishes the dentures to the teeth of the patient for a more natural dental procedure.

However, in the denture during the denture polishing process, the fine particles inevitably occur, so that the fine particles and dust can be sucked into the polishing worker, thereby causing a threat to the health of the worker.

1 to 3 is for the "movable dust collector" of the Republic of Korea Utility Model Registration No. 0264238 to solve the above problems, and serves to collect the fine particles in the polishing operation of the small workpiece.

Specifically, in the mobile dust collector, the opening and closing door (11A) is hinged to the front of the main body case 11, the interior of the main body case 11 is divided into a lower space and an upper space by the separating plate (P1). In addition, the opening / closing case 12 is coupled to the upper portion of the main body case 11 so as to be opened and closed by a hinge pivot, and the upper and lower plates P2 of the opening and closing case 12 are provided with a transparent window G forming an inclined surface. Water inlets H2 are formed through both sidewalls of the opening / closing case 12.

In addition, the discharge pipe (p) is coupled to the upper end through the upper surface (SU) of the main body case 11, the suction duct 14 is provided downward extending from the upper end of the discharge pipe (p). In addition, an upward opening filter 15 is coupled to a bottom surface of the separator plate P1 in the main body case 11, and a suction tube 16 on which the suction motor M is seated is disposed on an upper surface of the separator plate P1. The silencer 17 is coupled to one side of the suction tube 16, and the exhaust duct 18 penetrating the sidewall of the main body case 11 is coupled to one side of the silencer 17.

That is, the fine particles sucked through the discharge pipe (p) is moved to the lower space of the body case 11 and then the fine particles are filtered while passing through the upward open filter 15 in the process of moving from the lower space to the upper space, The purified air filtered with fine particles is discharged to the outside through the silencer 17 after being moved to the suction tube (16).

Therefore, it is possible to collect the fine particles generated during denture processing to discharge the purified air, and also to reduce the noise generated during the discharge of the purified air.

However, the above-mentioned conventional dust collector has to be precisely polished by putting a hand on both sides of the denture processing.
