Description

The present invention relates to a dust collector having an expandable suction range.

Materials used in nail art, such as coloring or painting the surface of nails, include nail polish, remover, oil, topcoat, and dryer, but the ingredients of these materials are mainly stimulating. There are many toxic chemical components that induce a odor or cause environmental pollution when diffused into the air.

When working on nail art using such materials, it is common to work in an open working environment on all sides, which inevitably makes workers and users harmful chemicals. Be exposed. Therefore, when performing nail art work for a long time in such an environment, there is a problem that the air in the work environment is contaminated, which may induce respiratory diseases of workers and users.

We also use handpieces for grinding work to smooth the surface of the nail and for care such as exfoliating the surrounding skin. However, since the conventional handpiece does not have a separate dust suction device, nail dust generated during work such as polishing and cutting nails using the handpiece scatters in all directions and adheres to clothes or stains the surroundings. It is also inhaled into the respiratory tract, causing problems that are not good for hygiene.

Therefore, conventionally, a nail dust collector for preventing the scattering of dust generated during nail art work has been proposed. In such a conventional nail dust collector, the worker looks down and works, so even if the dust is sucked during the nail care work, the distance to the worker is short, so the dust may be sucked and dust may be sucked into the eyes. It penetrates and has a serious impact on health, so improvement measures are needed.

Further, in the conventional dust collector, the suction input is not uniformly dispersed from the inside due to the distance between the motor and the suction port or the difference in the shape of the flow path, and the suction input is not uniformly dispersed from the inside, and is around the suction port formed in the high pressure region. Since only the concentration was concentrated, it caused the inhalation range to be narrowed.

Hereinafter, a preferred embodiment of a dust collector capable of expanding the suction range according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a dust collector whose suction range can be expanded according to the present invention, FIG. 2 is an enlarged view of a first suction port 210, and FIG. 3 is a user protection head 100 and an upper housing 200. FIG. 4 is a cross-sectional view showing the upper housing 200.

Referring to FIGS. 1 to 4, the dust collector having an expandable suction range according to the present invention includes a lower housing 300 in which a fan motor 500 is housed, an upper housing 200 upright on the upper surface of the lower housing 300, and an upper housing 200. Includes a user protection head 100 rotatably coupled in the vertical direction, and a removable filter assembly 400 to the lower housing 300.

The lower housing 300 has an internal space in which the fan motor 500 is provided, and is provided with a housing unit 310 (see FIG. 7) in which the filter assembly 400 is housed on one side. Here, the lower housing 300 may be provided with an operation panel provided with a power switch or the like on the upper surface or other wall surface.

The upper housing 200 includes a first suction port 210 and a second suction port 220 in which air containing dust is sucked into one surface of an upper body 230 that stands upright on the upper surface of the lower housing 300, and a whirlpool that prevents the generation of whirlpools inside the upper part. It may include a preventive measure and an upper hinge 240 that hinges to the user protection head 100.

Among them, the first suction port 210 is composed of a plurality of elongated holes on one surface of the upright upper main body 230. Here, the elongated hole has a difference in length extending in the vertical direction depending on the distance from the fan motor 500.

Taking the illustrated figure as an example, the first suction port 210 is composed of a plurality of elongated holes incised in the vertical direction, and the length of each elongated hole depends on the distance and / or position with the fan motor 500. Set. For example, the central portion where the suction input generated by the fan motor 500 acts most strongly extends so as to have the longest length. Further, the first suction port 210 is formed so that its length is gradually shortened with respect to the central portion.

That is, the upper housing 200 sucks the outside air at the suction pressure generated by the fan motor 500. However, inside the upper housing 200, there may be a region where the suction pressure acts high and a region where the suction pressure acts low, depending on the distance of the fan motor 500 and the shape of the flow path. Therefore, when both the width and the length of the elongated holes are uniformly formed, the suction pressure generated by the suction motor is not uniformly dispersed, and the dust suction can be concentrated only in the elongated holes closest to the fan motor 500.

Therefore, in the present invention, among the elongated holes constituting the first suction port 210, the elongated hole forming the central portion where the suction pressure acts the highest is formed according to the suction pressure difference of the upper housing 200, and this is formed. The length of the elongated holes aligned laterally in the center was gradually reduced.

In such an arrangement of the elongated holes, the elongated holes are further expanded in the portion where the suction input of the fan motor 500 acts strongly to increase the amount of air intake, and the elongated holes are narrowed in the region where the suction pressure of the fan motor 500 is low. It is characterized by reducing the amount of intake air and evenly distributing the intake and input.

The second suction port 220 is formed so as to extend horizontally on one surface of the upper main body 230 and sucks air containing dust. Here, the second suction port 220 sucks dust located on the lower side of the first suction port 210. Since the second suction port is relatively close to the fan motor, it is composed of a horizontally extending elongated hole.

That is, in the present invention, as a plurality of elongated holes, a first suction port 210 composed of vertically elongated holes having different lengths depending on the suction pressure difference and a second suction port composed of a horizontally extending single elongated hole. The 220 is formed below the first suction port at a position close to the fan motor 500.

Further, one surface of the upper housing 200 on which the first suction port 210 is formed may be formed by an inwardly curved surface. Such an inwardly curved surface can guide the flow of air so that the surrounding air flows toward the first suction port 210 along the curved surface.
The whirlpool prevention means 250 will be described with reference to FIGS. 5 and 6. FIG. 5 is an enlarged view showing the whirlpool prevention means of FIG. 4, and FIG. 6 is a perspective view showing the whirlpool prevention means of FIG.

Referring to FIGS. 5 and 6, the whirlpool prevention means 250 has a vertical rib 252 extending downward inside the upper body 230 to divide the space and a horizontal rib 251 extending horizontally intersecting the vertical rib 252. Including.

The vertical rib 252 extends downward so that both ends are connected to one surface and the opposite surface of the upper housing 200, respectively, and divides the internal space above the upper housing 200.
The horizontal ribs 251 are one or more, and are formed so as to extend in a direction intersecting the vertical ribs 252.

Such horizontal ribs 251 and vertical ribs 252 serve to obstruct the flow of air so that the air sucked through the first suction port 210 does not form a whirlpool on the upper side of the upper housing 200. In particular, the air flowing into the lower side of the first suction port 210 along the curved surface may generate a whirlpool when the flow path is formed upward and hits the inner wall surface of the upper housing 200. Such whirlpools can block the air discharged from the upper housing 200 to the lower housing 300.
Therefore, the present invention is provided with whirlpool prevention means 250 inside the upper housing 200 in order to prevent such whirlpool formation.

The upper hinge 240 includes a fastening port 241 projecting from the side portion of the upper housing 200 and forming a hole inside, and a guide plate 242 projecting laterally around the fastening port 241 to guide the user protection head 100. ..
The fastening port 241 projects from the side surface of the upper housing 200, and a hole is formed in which the hinge shaft of the user protection head 100, which will be described later, is rotatably fastened.

The guide plate 242 projects from the side surface of the upper housing 200 around the fastening port 241 to guide the rotation direction and range of the user protection head 100. Preferably, the guide plate 242 may include a stopper (not shown) so that the rotation range of the user protection head 100 can be limited. The stopper is provided with a protrusion or groove at any one point of the guide plate 242 so as to limit the rotation range of the user protection head 100, and the user protection head 100 is a structure that is inserted or locked into the protrusion or groove. Consists of.

The user protection head 100 includes a transparent window 120 made of a transparent material, a fixed frame 110 for fixing the transparent window 120, and a head hinge 130 hinged to the upper housing 200.

The transparent window 120 is made of a transparent material such as plastic or glass, and shields the upper side of the first suction port 210 so as to prevent the user from sucking dust. That is, the user can perform the nail care work by locating the hand below the transparent window 120 after the head is located above the transparent window 120.

Here, the upper housing 200, the lower housing 300 or the user protection head 100 may further be provided with lighting means to illuminate the working space between the transparent window 120 and the upper side of the lower housing 300 for convenience of work. The lighting means is, for example, an LED lamp, which emits light when the switch is turned on to illuminate the work space under the transparent window 120.

The fixed frame 110 fixes the transparent window 120. That is, the fixed frame 110 is, for example, separated and coupled to the upper part and the lower part and fastened to the outside of the transparent window 120.

The head hinge 130 is rotatably fastened to the upper hinge 240 extending downward by the fixed frame 110. Here, the head hinge 130 includes a hinge rod 131 inserted into the fastening port 241 and a support plate 132 that supports the hinge rod 131.

The support plates 132 are a pair separated from each other and project downward from the lower surface of the fixed frame 110. The support plate 132 rotates at a position in close contact with or close to the outer surface of the guide plate 242. Therefore, the support plate 132 includes an anti-friction groove 132a incised at the end of contact with the guide plate 242 so as to minimize the frictional force with the guide plate 242.
The hinge rod 131 protrudes from the guide plate 242 and is inserted into the fastening port 241 of the upper hinge 240.

The filter assembly 400 is configured to be removable from the lower housing 300, and dust is filtered into the air sucked through the upper housing 200 to discharge purified air. A description of such a filter assembly 400 will be described with reference to FIGS. 7 and 8.
FIG. 7 is an exploded perspective view of the filter assembly 400 and the lower housing 300, and FIG. 8 is a perspective view showing the tray 410 and the filter cleaning means 430.

With reference to FIGS. 7 and 8, the filter assembly 400 includes a filter 420, a tray 410 containing the filter 420, and a filter cleaning means 430 for removing dust from the filter 420.
The tray 410 includes a discharge portion 411 that discharges purified air, an opening 412 into which air containing dust flows in, and a guide rail 413 that extends to the opening 412.

The opening 412 is a wall surface in a direction in which the housing portion 310 is drawn in, and is an inlet for air containing dust that has been opened and transmitted to the upper housing 200 and the lower housing 300.
The discharge unit 411 discharges the air from which the dust has been removed to the outside while the air flowing in through the opening 412 passes through the filter 420.
The guide rail 413 extends one or more in one direction at the opening 412 and supports the filter cleaning means 430 so that it can move.

That is, the tray 410 constitutes both side walls, a ceiling surface, and a bottom surface so as to form a space in which the filter 420 is stored, and the wall surface on the storage portion side of the lower housing 300 is opened to form an opening 412. , A discharge portion 411 from which purified air is discharged is formed on a wall surface facing the opening 412.
The filter cleaning means 430 includes a tip 431 that contacts the filter 420 through the opening 412 of the tray 410 and a handle 432 that extends rearward at the tip 431.
The tip 431 includes an inwardly facing separation groove 431a and a striking protrusion projecting between the separation grooves 431a.

The separation groove 431a is incised so as to face inward at the tip 431, and the guide rail 413 is fitted. Therefore, when the tip 431 moves along the guide rail 413, the separation groove 431a guides the tip 431 to prevent detachment and slide in a predetermined direction.

The striking protrusion 431b extends downward between the separation grooves 431a. Therefore, when the guide rail 413 is fitted into the separation groove 431a of the tip 431, the striking protrusion 431b is pulled into the inside of the opening 412 through the space between the guide rails 413 and comes into contact with the filter 420. Therefore, if the tip 431 moves along the guide rail 413, the striking protrusion 431b moves while striking the filter 420, so that the dust accumulated on the filter 420 can be removed.

Therefore, if the user fastens the tip 431 to the opening 412 so that the guide rail 413 is fitted into the separation groove 431a, grasps the handle 432 and slides the guide rail 413, the striking protrusion 431b pulled in between the guide rails 413 opens. Move while striking the filter 420 inside the 412. Therefore, the dust accumulated on the filter 420 is separated by the contact and friction of the striking protrusion 431b.

Here, the handle 432 is provided with a fixing protrusion (not shown) extending rearward at the tip 431 and projecting to either the outside of the lower housing 300 or the tray 410 cover, and the fixing protrusion (not shown). The handle 432 may include a fixing hole 432a so as to be coupled to.

That is, in the present invention, the filter cleaning means 430 is stored and cleaned by fastening the fixing hole 432a of the handle 432 to the fixing protrusion (not shown) formed in either the lower housing 300 or the tray 410 cover. It is preferable to configure the filter cleaning means 430 so that it can be used separately only occasionally.

The embodiments of the present invention described above are merely exemplary, and any person having ordinary knowledge of the technical field to which the present invention belongs can make various modifications and equal other embodiments based on the above. Can be understood to be.
