Referring to Figures 1-5, a blaster 100 according to one embodiment may process the surface of an object-specifically, the surface of a tooth. The blaster 100 may include a first container 110, a second container 120, an injector 130, and a coupler 140.

The first container 110 may comprise a pressurized fluid. In one example, the compressed fluid may comprise an inert gas. In a preferred example, the inert gas may comprise nitrogen. The compressed fluid is received inside the first container (110). The compressed fluid may have a phase suitable to be received within the first container 110. In one example, the first container 110 may have a cylindrical shape. In one embodiment, the first container 110 may be sized to grip by a user's hand.

The second container 120 may include a brassive. The abrasive is sprayed onto the surface of the object, and the surface of the object is treated by the sprayed abrasive. In one example, the abrasive may comprise sand. The abrasive is accommodated inside the second container 120. In one example, the second container 120 can be screwed into the coupler 140. In one example, the second container 120 may include a cap that is openably and closably installed in the second container 120 to supplement additional abrasive material to the second container 120.

The injector 130 may inject the compressed fluid and / or the abrasive to the outside. When the compressed fluid from the first container 110 and the abrasive from the second container 120 are mixed, the injector 130 can jet the mixed compressed fluid and the abrasive to the outside.

The coupler 140 may couple the first container 110 to the second container 120 and the injector 130, respectively. The pressurized fluid in the first container 110 can be mixed with the abrasive in the second container 120 and the first container 110, the second container 120, and the injector 130 can be in fluid communication with each other. have.

In one embodiment, the blaster 100 may have a structure to achieve portability of the user. The coupler 140 may couple the first container 110 to the second container 120 and the injector 130 so that the coupler 140 can be detachably attached to the second container 120 and the injector 130. When the amount of the compressed fluid in the first container 110 is insufficient, the user separates the first container 110 from the second container 120 and the injector 130 to fill the first container 110 with the compressed fluid The first container 110 containing the filled compressed fluid may be coupled to the second container 120 and the injector 130 through the coupler 140 to use the blaster 100. [

The first container 110, the second container 120, the injector 130, and the coupler 140 may be integrated. The conventional blaster has a structure in which a large-sized compressor and a hand-type handpiece are hose-connected to each other so that portability is remarkably low. On the other hand, the blaster 100 according to an embodiment includes a first container 110, 120, the injector 130, and the coupler 140 may be integrated to significantly enhance the portability of the user.

The coupler 140 may include a main passage 142. The main passage 142 may connect the first container 110, the second container 120 and the injector 130 so that the first container 110, the second container 120 and the injector 130 are in fluid communication with each other. have.

The main passage 142 is configured to extend from the first container 110 and the second container 120 to the injector 130. The compressed fluid from the first container 110 and the abrasive from the second container 120 can flow onto the main passage 142. [ In one example, the pressurized fluid from the first container 110 and the abrasive from the second container 120 may be mixed on the main passage 142.

In one embodiment, the first container 110 and the main passageway 142 may be selectively coupled. When the first container 110 and the main passage 142 are coupled to each other, the compressed fluid can flow from the first container 110 to the main passage 142. Coupling between the first container 110 and the main passage 142 may block the flow of the compressed fluid from the first container 110 to the main passage 142.

In one embodiment, the blaster 100 may be configured to remove abrasive residues remaining in the injector 130.

The coupler 140 may include a bypass passage 144. The bypass passage 144 is connected to the first container 110 and the main passage 142 and the compressed fluid from the first container 110 can flow. The pressure inside the bypass passage 144 can be adjusted relatively to the pressure inside the main passage 142. [

When the pressure inside the bypass passage 144 is maintained to be smaller than the pressure inside the main passage 142, the flow of the compressed fluid on the bypass passage 144 is restricted, And flows along the passage 142 and mixes with the abrasive from the second container 120. The mixed compressed fluid and the abrasive can be injected along the main passage 142 through the injector 130. [

On the other hand, when the pressure inside the bypass passage 144 is kept larger than the pressure inside the main passage 142, the flow of the compression fluid on the main passage 142 is limited, As the fluid flows, the abrasive remaining in the injector 130 can be accommodated in the second container 120 by the pressure inside the bypass passage 144.

In one embodiment, the blaster 100 may further include a trigger 150. The trigger 150 selectively converts between a first state in which the first container 110 and the main passage 142 are in fluid communication and a second state in which the first container 110 and the bypass passage 144 are in fluid communication, can do. In the first state, the first container 110 and the main passage 142 are coupled while the first container 110 and the bypass passage 144 are de-coupled. In the second state, the first container 110 and the main passage 142 are de-coupled while the first container 110 and the bypass passage 144 are coupled. Coupling or de-coupling of the first container 110 and the main passage 142 or coupling or de-coupling of the first container 110 and the bypass passage 144 may be performed by a mechanical method , An electronic scheme, or a combination thereof.

As a result, in the first state, the compressed fluid from the first container 110 and the abrasive from the second container 120 can flow to the injector 130 along the main passage 142, The mixed compressed fluid and the abrasive are ejected to the outside. On the other hand, in the second state, the compressed fluid mixed from the injector 130 and the abrasive agent are blocked from flowing to the outside, and the abrasive agent remaining in the injector 130 can be accommodated in the second container 120.

4 and 5, the coupling structure between the first container 110 and the main passage 142 and the coupling between the first container 110 and the bypass passage 144 are shown in FIGS. 4 and 5, An example of the structure is shown.

The second opening 154 formed in the shaft 151 of the trigger 150 is aligned with the bypass passage 144 while the trigger 150 is in the first state in which the trigger 150 is inoperative The pressurized fluid may flow along the path from the outlet 112 of the container 110 to the bypass passage 144 via the second opening 154. In the first state, the first opening 152 formed in the shaft 151 of the trigger 150 is not aligned with the main passage 142, so that the pressure in the first passage 110 from the first container 110 to the main passage 142 The flow of the fluid is blocked.

5, the first opening 152 formed in the shaft 151 of the tricer 150 is aligned with the main passage 142, so that the first container 152 The compressed fluid can flow along the path from the outlet 112 of the first passage 110 to the main passage 142 via the first opening 152. [ On the other hand, in the second state, since the second opening 154 formed in the shaft 151 of the trigger 150 is not aligned with the bypass passage 144, the bypass passage 144 is opened from the first container 110, The flow of the pressurized fluid to the pressurized fluid is blocked.

Although not shown, the blaster 100 according to one embodiment may include a main valve on the main passage 142 and a bypass valve on the bypass passage 144. The main valve and the bypass valve can be selectively controlled to be actuated mechanically and / or electronically by the trigger 150. For example, when the main valve is operated and the bypass valve is non-operated, the flow of compressed fluid from the first container 110 to the main passage 142 is allowed and the bypass passage 144 can be blocked. On the other hand, when the main valve is non-activated and the bypass valve is operated, the flow of the compressed fluid from the first container 110 to the main passage 142 is blocked and the bypass passage 144 is opened from the first container 110, Lt; / RTI > flow of the pressurized fluid can be permitted.

In one embodiment, the coupler 140 may include a mixing chamber 146. The mixing chamber 146 is a portion where the abrasive from the second container 120 is charged. The mixing chamber 146 may be connected to the first container 110, the second container 120, and the injector 130, respectively. When the pressurized fluid flows from the first container 110 to the mixing chamber 146, the pressurized fluid from the first container 110 and the abrasive from the second container 120 can be mixed in the mixing chamber 146 .

In one embodiment, the main passageway 142 may be configured to extend from the first container 110 via the mixing chamber 146 to the injector 130. In one example, the main passageway 142 may include a path from the first container 110 to the mixing chamber 146 and a path from the second container 120 to the mixing chamber 146, respectively. In another example, the main passageway 142 may include a path from the first container 110 through the second container 120 to the mixing chamber 146 as a single path.

In one embodiment, the blaster 100 may include a structure configured to enhance the mixing efficiency of the pressurized fluid and the abrasive. The main passage 142 may include a first conduit 1421 and a second conduit 1422. The first conduit 1421 is configured to extend from the first container 110 to the mixing chamber 146 and the second conduit 1422 is configured to extend from the mixing chamber 146 to the injector 130, The conduit 1421 and the second conduit 1422 can be separated from each other in the mixing chamber 146. When the compressed fluid from the first container 110 flows into the mixing chamber 146 along the first conduit 1421 a mixing action occurs between the introduced compressed fluid and the abrasive charged in the mixing chamber 146, The mixed compressed fluid and the abrasive are injected to the outside through the injector 130 along the second conduit 1422. Since the clearance between the first conduit 1421 and the second conduit 1422 is provided to allow the compressed fluid and the abrasive to mix, the mixing efficiency of the compressed fluid and the abrasive can be improved.

The end of the first conduit 1421 and the end of the second conduit 1422 may each protrude from the inner wall of the mixing chamber 146 toward the center of the mixing chamber 146. In one embodiment, This structure allows the flow of fluid along the first conduit 1421 relative to the structure in which the end of the first conduit 1421 and the end of the second conduit 1422 are positioned substantially within the interior wall of the mixing chamber 146 And the mixed pressurized fluid and the abrasive can be easily introduced into the second conduit 1422 while a relatively strong mixing action occurs between the abrasive in the pressurizing fluid and the mixing chamber 146. [

The length of the protruding portion of the first conduit 1421 in which the first conduit 1421 protrudes from the inner wall of the mixing chamber 146 and the length of the second conduit 1422 protruding from the inner wall of the mixing chamber 146 The level of the abrasive in the interior of the mixing chamber 146 may be maintained such that the length of the protruding portion of the second conduit 1422 is greater than or equal to the level of the abrasive charged into the interior of the mixing chamber 146 . Accordingly, the flow of the abrasive in the mixing chamber 146 into the first conduit 1421 and / or the second conduit 1422 is reduced, so that the flow of the compressed fluid and the abrasive can be smoothly performed.
