Description

SEPARATOR FOR SUCTION DEVICE

The present invention relates to a separator for a suction device, and more particularly, to a separator for a suction device capable of increasing water separation efficiency and capable of discharging residual moisture and residual foreign matter to the outside of the separator easily.

Generally, during the treatment and treatment of the dentist, foreign substances such as blood and tooth scraps, such as blood and saliva, are generated inside the oral cavity of the patient, and such moisture and foreign substances are sucked out from the oral cavity using a suction device and discharged.

Such a suction device generates vacuum pressure while the separator is driven by driving of the vacuum pump, and sucks moisture and foreign matter into the separator by the suction force by the vacuum pressure. At this time, the foreign matters are filtered through the filter, and only air and moisture are sucked into the separator.

The moisture sucked into the separator is discharged to the outside of the separator through the drain port while moisture is separated through the impeller provided inside the chamber constituting the separator.

However, in the conventional separator for a suction device, the impeller has a cylindrical shape, which lowers the water separation efficiency.

That is, the water flows into the chamber together with the air, and then the water is dispersed in the vortex form by the rotation of the impeller, and then the water is separated by the self weight to be discharged downward into the drain port. The impeller is cylindrical The vortex does not occur largely, and the centrifugal force is weak, so that the water separation efficiency is low.

If the water is not completely separated from the impeller due to the low water separation efficiency, it may cause corrosion of the various components constituting the suction device due to moisture that can not be removed and cause the failure of the device.

Also, in the conventional separator for a suction device, a part of moisture that can not be removed from the impeller is dropped and stored in the lower plate. When the driving of the separator is stopped, the check valve is opened and discharged to the outside. The check valve is clogged by foreign substances and the water is not smoothly discharged.

In particular, in winter, the impeller freezes due to the residual moisture, or the check valve does not freeze and open, so that it does not work when restarting the suction device.

The impeller provides a separator for a suction device having an outer surface formed with a tapered surface so as to increase the centrifugal force and to increase the water separation efficiency when separating moisture in the air introduced into the chamber.

The tapered surface of the impeller is formed in such a shape that the outer diameter of the cross section gradually decreases while moving from the lower part to the upper part of the impeller.

A discharge inducing vane for guiding air and moisture to the upper side of the chamber is formed along the lower circumferential surface of the impeller and the falling induction vanes for inducing the drop by restricting the water from rising further along the upper circumferential surface of the impeller are .

The discharge-inducing vanes are straight and positioned in a vertical direction.

The bottom plate has a bottom surface in a planar shape and a side wall of the bottom plate has a discharge hole through which residual moisture is discharged.

A filter for filtering foreign substances contained in air sucked into the chamber is provided outside the chamber, and the filter is connected to a felt cap so that the filter can be easily mounted and removed.

The separator for a suction device according to the present invention is characterized in that the outer surface of the impeller is formed as a tapered surface, and a large centrifugal force acts on the outer surface of the impeller as compared with the prior art, so that the moisture introduced into the chamber can be separated with high efficiency.

Accordingly, the failure factor of the suction device due to moisture that has not been removed can be reduced, and the service life of the suction device can be prolonged.

Further, when there is residual water or residual foreign matter that can not be removed, the water is discharged immediately through the drain hole formed in the side surface of the lower plate, so that the suction device can be smoothly operated when it is not used for a certain period of time and then restarted again.

This makes it possible to prevent the impeller from freezing due to residual moisture, especially in winter.

Fig. 1 is a perspective view of a separator for a suction device according to the present invention, Fig. 2 is an exploded perspective view of a separator for a suction device according to the present invention, Figs. 3a and 3b are a cross- 4A and 4B are a perspective view and a front view of an impeller provided in a separator for a suction device of the present invention, and FIGS. 5A and 5B show a perspective view and a front view of a lower plate provided in the separator for a suction device of the present invention.

As shown in the figure, the separator for a suction apparatus according to the present invention comprises a chamber 2, a vacuum pump 4 for forming a vacuum inside the chamber 2, And an impeller 6 which rotates by driving of the pump 4 and sucks air and moisture into the chamber 2 to separate moisture.

The chamber 2 has a cylindrical shape with upper and lower ends opened, and an upper plate 8 and a lower plate 10 are assembled to the upper and lower ends of the chamber 2, respectively.

A filter 11 is provided outside the chamber 2 for filtering out foreign substances contained in the air sucked into the chamber 2. A filter cap 13 is connected to the filter 11 so that the filter 11 can be easily mounted and separated.

The moisture to be sucked into the chamber 2 may be, for example, occurring inside the patient's mouth during the treatment and treatment of the dentist.

For example, the moisture refers to a liquid such as blood or saliva generated in the oral cavity of a patient, and the foreign substance is a solid dental filling used for filling a tooth with a dental material in a patient's tooth fragment or a dental treatment process Debris and the like.

The chamber 2 is formed with an inlet port 12 and a drain port 14 and an air outlet port 16. The inlet port 12 is a member in which moisture and foreign matter generated inside the oral cavity of the patient are guided together with air.

When the water drawn into the chamber 2 through the inlet 12 is separated by the impeller 6 and then falls down to the bottom of the chamber 2 due to its own weight, the drain hole 14 is closed by the rotational force of the impeller 6 And the air outlet 16 is a portion where the air inside the chamber 2 is discharged to the outside.

The vacuum pump 4 is for generating a predetermined suction force by forming the inside of the chamber 2 in a vacuum state. Since the vacuum pump 4 can be applied to a vacuum pump which is generally used in a medical device for suction, The description is omitted.

The impeller 6 installed inside the chamber 2 rotates so as to draw moisture together with the air through the inlet 12 and to separate water by centrifugal force.

The impeller 6 provided in the present invention is formed with a tapered surface 18 on its outer surface so as to increase the centrifugal force and increase the water separation efficiency when the water sucked into the chamber 2 is separated.

The tapered surface 18 may be formed such that the outer diameter of the tapered surface 18 gradually decreases from the lower portion of the impeller 6 toward the upper portion thereof.

When the outer surface of the impeller 6 is formed of the tapered surface 18, a larger vortex is generated in the chamber 2 than in the case of the linear shape. As a result, the moisture introduced into the chamber 2 A large centrifugal force acts to increase the water separation efficiency.

That is, the tapered surface 18 gradually decreases in outer diameter from the lower part of the impeller 6 to the upper part, and the centrifugal force gradually increases from the lower part to the upper part of the impeller 6, and water is scattered toward the inner wall of the chamber 2 All separate.

If the moisture introduced into the chamber 2 is completely separated as described above, various components constituting the suction device are not affected by moisture, so that corrosion of the components of the suction device is prevented, thereby preventing a cause of failure of the suction device.

The impeller 6 has a plurality of discharge inducing vanes 20 formed on the lower circumferential surface thereof so as to raise the water and air introduced through the inlet 12 of the chamber 2 while swirling upward, A plurality of drop guiding wings (22) are formed on the upper circumferential surface to block the rising water from further rising.

When the discharge inducing vane 20 and the drop guiding vane 22 are integrally formed in the one-side feller 6, the impeller 6 is structurally simplified and thus the impeller 6 can be easily manufactured.

When the driving of the vacuum pump 4 is stopped, the discharge inducing vane 20 is preferably vertically installed in a straight shape so that water and residual foreign matter on the discharge inducing vane 20 can flow smoothly .

The moisture removed through the impeller 6 is drained to the outside through the drain port 14. If the separated moisture is not drained to the drain port 14, residual moisture may exist in the chamber 2 together with residual moisture, They fall to the lower plate 10 assembled in the lower part of the chamber 2. [ A drain hole 26 is formed in the side wall 24 of the lower plate 10 so that the residual moisture and foreign matter can be discharged easily to the outside easily.

The bottom surface of the lower plate 10 has a flat inner surface so that when the remaining moisture and the remaining foreign matter fall, they can be immediately discharged to the outside through the discharge hole 26 without remaining.

When the residual moisture and residual foreign matter that have not been removed from the separator and are immediately discharged to the outside, the impeller 6 adheres to the lower plate 10 due to the freezing of water remaining in the winter season and the like, It is possible to prevent the cause of the failure or the failure to occur.

Reference numeral 28 denotes a case for installing and supporting the chamber 2 and the inlet 12, the drain 14 and the air outlet 16. Reference numeral 30 denotes a case where the noise of the vacuum pump 4 Quot; silencer "

In the separator for a suction device according to the present invention, when the power switch (not shown) is turned on, the vacuum pump 4 is driven to rotate the impeller 6.

Then, while vacuum is formed in the chamber 2, air, moisture, foreign substances, and the like are mixed with the air through the inlet 12, and foreign substances are filtered through the filter 11, and air and moisture are sucked into the chamber 2 .

The air and the moisture sucked into the chamber 2 are vortexed in the chamber 2 due to the rotational force of the impeller 6, so that the water is scattered to the inner wall of the chamber 2 by the centrifugal force due to vortex, The water that flows downward or falls down due to its own weight. The separated water is discharged through the drain port 14 and the air is discharged through the air discharge port 16, respectively.

At this time, the outer surface of the impeller 6 is formed of the tapered surface 18, so that a larger vortex is formed in the chamber 2, and a larger centrifugal force acts on the water introduced into the chamber 2, And is separated by the inner wall of the casing.

In this operation, the discharge inducing vane 20 rotating together with the impeller 6 serves to raise water and air upward, and the drop guiding vane 22 serves to prevent the raised water from rising further So that water can be separated from the discharge inducing vane 20 and the drop inducing vane 22 by centrifugal force.

As the water is separated by the rotation of the impeller 6, the air sucked into the chamber 2 is discharged to the outside through the air outlet 16. The separated water is scattered to the inner wall of the chamber 2, When it falls to the lower side of the chamber 2 due to its own weight, it is drained to the outside of the chamber 2 through the drain port 14 by the rotational force of the impeller 6.

In order to stop the use of the suction device, when the power switch is turned off, the driving of the vacuum pump 4 is stopped, and the rotating impeller 6 also stops rotating, and the vacuum pressure inside the chamber 2 is released, .

Residual moisture may be present when the separator is stopped or operated, and the residual moisture falls to the lower plate 10 due to its own weight and is immediately discharged to the outside through the discharge hole 26.

As a result, the residual moisture is immediately discharged to the discharge hole 26 without remaining, thereby preventing the impeller 6 from freezing in the winter season.

While the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
