Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dust collector used when a dental technician, a dental student or the like grinds a tooth shape, a denture or the like.
[0002]
[Prior art]
Dental materials include plaster, plastics, ceramics, metals, etc. When grinding a tooth mold, dentures, etc. made of these, the material is scattered as dust and the working environment is significantly deteriorated, and It is unsanitary. For this reason, an apparatus for preventing the dust from being scattered and collecting it has been devised (for example, Japanese Utility Model Laid-Open No. 6-41711).
[0003]
In the prior art, the work space is surrounded by a main body cover, and the main body cover is composed of a base, a top plate, and a rear plate connecting the base and the top plate on the rear side.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
In FIGS. 1 and 2, 1 is an example of the dust collector of the present invention, 2 is a work table, 3 is a suction mouse body, and the suction mouse body 3 is well known in the dental arts industry and is made of plastic material. is formed in a substantially funnel-shaped, having a wide suction inlet 3 _1. Then, the suction port 3 ₁ is attached to the front side 2 ₁ of the work table 2, that is, the operator side with the appropriate fixing means 4 facing the front side.
[0010]
A flexible or semi-rigid suction hose 5 is connected to the lower end of the suction mouse 3, and is further connected to a suction device via a dust removing portion. The fixing means 4 may be provided on the suction hose 5.
[0011]
A transparent hood 6 made of a transparent plastic material and having a shallow U-shaped cross section is attached to the upper surface of the suction mouse body 3 so that it can be turned up and down by a fixing member 7 such as a pin or a screw. Yes.
[0012]
On worktable second end ₆₁ near the bottom of the transparent hood 6, the air supply chamber 8 extending in the horizontal direction is installed, a long air outlet 9 on the upper surface thereof is opened,該吹outlet 9, a transparent hood It is directed to a lower surface of the sixth end portion ₆₁ side of the. It is preferable that the air supply chamber 8 has a convex arcuate shape or a reverse U shape so that the blown air gathers on the entire lower surface of the transparent hood 6. The air supply hose 10 is connected to an air supply device (not shown).
[0013]
The dust collector 1 sucks air from the suction port 3 ₁ into the intake mouse body 3 by the suction hose 5 and simultaneously discharges the blown air A ₁ from the outlet 9 around the circumference at a speed of about 0.5 m / s. The operator is sitting on the back side of the inhalation mouse, and the work is made of dental material by putting his hands into the work space 11 below the transparent hood 6 from both sides as shown in FIG. W is processed. In the work space 11, a suction air flow is generated in a wide range as shown by B ₁ , B ₂ , and B ₃ , and the fine powder generated in the work space 11 is sucked into the suction mouse main body 3 together with the air, Then, it is sent to a dust removal unit outside the figure and separated.
[0014]
If the speed of the air blown out from the air outlet 9 is excessive, an action to wind up dust occurs, the ventilation action becomes uneven in the narrow work space 11, and the dust tends to partially flow. It is preferable to blow out at a speed.
[0015]
In this dust collector 1, there are only an air supply chamber 8 and a suction mouse main body 2 in the vicinity of the work space 11, and the suction mouse main body 2 has a minimum size necessary for intake. Therefore, there is nothing in the work space 11 that obstructs the work, and in addition, there is an advantage that the work can be easily performed because the suction mouse body 3 is transparent.
[0016]
In the embodiment shown in FIG. 3, the configurations of the suction mouse body 3 and the transparent hood 6 in the dust collector 1 are the same as those in FIGS. 1 and 2, but the arrangement of the air supply chamber 8 is different. In this embodiment, the air supply chamber 8 is embedded in the work table 2, and the air outlet 9 is opened on the upper surface of the work table 2.
[0017]
By adopting such a configuration, even if the air outlet 9 is provided close to the suction mouse body 3, the upper surface of the work table 2 is substantially flat only by opening the slit-like air outlet 9. It is easy to work, and in this case, dust that tends to leak to the worker side is effectively prevented by the air curtain formed by the air coming out from the outlet 9 on the hand side.
[0018]
Further, in the embodiment shown in FIG. 4, a hollow transparent hood 12 is used instead of the transparent hood 6, and the air A ₂ is discharged downward from the air outlet 12 ₁ on the lower surface of the tip to form an air curtain. Reference numeral 13 denotes an air supply hose.
[0019]
In the embodiment of FIG. 5, an outlet pipe 14 is provided along the lower peripheral edge of the transparent hood 6, and an air supply hose 15 is connected thereto.
[0020]
A slit-like outlet 14 _{1 in} the pipe length direction is provided on the lower surface of the outlet pipe 14 to form an air curtain by a downward airflow in the same manner as the outlet air A _{2 in} FIG. And is sucked into the suction mouse body 3.
[0021]
In the present invention, since the air curtain is formed by the air blown out from the air outlets 9, 12 ₁ , 14 _1, etc., a sufficient dust collecting action can be performed even if the air suction amount of the suction mouse body 3 is halved. In addition, due to the nature of the pump, the power consumption is reduced to one-eighth by halving the amount of intake air. According to the experiment, even if the power consumption for the air curtain is added, the power consumption can be reduced as compared with the case where dust is collected using only the suction mouse body, and dust leakage is almost prevented.
[0022]
In particular, there are many dust collectors installed in classrooms such as dental technical schools and dental universities, and there are some 400 installed in large schools, and the power consumption when these are used all together is enormous. Thus, power consumption is greatly reduced by using the apparatus of the present invention.
[0023]
Moreover, being able to halve the amount of air sucked in means that the amount of air flowing into the classroom can be halved, and if the classroom is air-conditioned, the amount of air to be newly conditioned will also be halved. The profit which can also save the power for air conditioning arises.
[0024]
【The invention's effect】
As apparent from the above description, according to the invention of claim 1, and those fixed to worktable transparent hood suction mouse body mounted rotatably, from the entire circumferential edge lower surface position of the hollow transparent hood Since it only includes an air supply chamber having an air outlet that blows downward air to form an air curtain, the configuration is simple and can be made inexpensively. In addition, the only part that obstructs the work is the main body of the suction mouse, but the main body of the suction mouse has a minimum size necessary for sucking air, so the entire apparatus is extremely small. Since the height can be adjusted by rotating the hollow transparent hood, there is an effect that it is easy to work.
[0025]
According to the invention of claim 2, since the air outlet for forming the air curtain is provided along the lower surface of the entire periphery of the transparent hood, there is no need to provide an air supply chamber on the work table, and the configuration is claimed. There is an advantage that it is simpler and smaller than that of Item 1.
[0026]
Furthermore, in the first and second aspects of the invention, there is no dust scattering even if the amount of suction air is reduced by half, so that there is an advantage that energy for dust collection and air conditioning can be greatly reduced.
