1 is a block diagram of an SSD shredder having a curved crushed surface according to one embodiment of the disclosed technique. Referring to FIG. 1, the SSD crusher having a curved crushed surface includes a housing 110, an inlet 120, a first roller 130, a second roller 140, and a driving unit 150.

The housing 110 means the body of the SSD crusher and a predetermined space is formed therein. In this space, debris of shredded SSD is collected. In one embodiment, the housing 110 includes a housing 110a, and collects debris from the housing 110a where the SSD is shattered.

Referring to FIG. 2, the housing 110 is provided with at least one button 110b for controlling the operation of the crusher. In one embodiment, the housing 110 may include at least one of an on button for operating the crusher, an off button for terminating the operation of the crusher, and a reverse button for reversing the driving direction of the two rollers for crushing the SSD. A button for reversing the motor 150a may be further provided in case the motor 150a is overloaded. Of course, it is also possible that the motor 150a itself is equipped with a latching function, and the motor 150a is automatically rotated counterclockwise, and then rotated again when the foreign object is removed.

Meanwhile, the at least one button 110b is disposed on the upper surface of the housing 110. The buttons 110b may be disposed on one side of the inlet 120 formed on the upper surface of the housing 110. [

An inlet 120 is formed on the upper surface of the housing and an SSD is inserted. In one embodiment, the through-hole 120 may have a predetermined width depending on the width of the body of the SSD. The SSD can be raised by the user along the through hole.

On the other hand, as shown in FIG. 1, the inlet 120 has a predetermined depth. In one embodiment, a slot having a length greater than the length of the body of the SSD may be formed. This is to prevent the occurrence of safety accidents due to the use of the crusher. For example, it is possible to form the injection port deep by a certain length so that the finger is not sucked or the finger does not touch the roller.

Meanwhile, the SSD crusher according to the disclosed technique includes two rollers 130 and 140. The first roller 130 is disposed inside the housing 110 and rotates along the central axis. And a first crushing surface for crushing the SSD, wherein the first crushing surface has a curvature. In one embodiment, as shown in FIG. 3, when viewed from above, the surface may be curved, such as U or S rather than flat. The second roller 140, which is paired with the first roller 130, is also formed in a curved plane.

Referring to FIG. 4, the first roller 130 has a plurality of blades along a curved first crushing surface. In an embodiment, each of the blades may be formed with an edge having a different height and a different angle so that the plurality of blades may be disposed in a curved shape on the surface of the first roller 130. The second roller 140 also has a plurality of blades arranged in the same manner as the first roller 130 and each blade has an edge having a different height and a different angle so that the second broken surface of the second roller 140 Make it look curved.

Here, the first crushing surface means one surface on which the blades are arranged on the first roller 130, and the second crushing surface means one surface on which the blades are arranged on the second roller 140. In one embodiment, the first and second crushing surfaces are disposed in contact with each other, and the first and second crushing surfaces and the second crushing surface are in contact with each other. May rotate in different directions.

Here, the first roller 130 and the second roller 140 are required to crush the SSD inserted through the input port 120 disposed on the upper surface of the housing 110, . For example, if the first roller 130 rotates clockwise, the second roller 140 may be turned counterclockwise to operate to allow the SSD to be sucked in between the two.

On the other hand, the blades of the first roller 130 and the blades of the second roller 140 are formed to mesh with each other. For example, the blades of the first roller 130 and the blades of the second roller 140 may be gears that rotate like gears. At this time, since the first and second crushing surfaces of the respective blades are curved, but they are in contact with each other, it is possible to rotate the blades without being tangled or broken.

Meanwhile, as described above, the first roller 130 and the second roller 140 are curved with each other but are returned to the engaged state, so that the inserted SSD is crushed in an irregular pattern different from the conventional one. In one embodiment, in the case of a conventional crusher, the crushing planes of the two rollers are planar, and blades having the same size and edge are formed on each plane, so that when the SSD is inserted, it is crushed into a uniform pattern, In the embodiment, the crushing surfaces of the two rollers are curved, and blades having different sizes and edges are formed, so that the SSD is crushed while being crushed, so that it is possible to crush the crushed pieces of the irregular pattern.

Further, as described above, since each of the blades has different heights and edges, the area contacted with the SSD becomes significantly smaller than that of the conventional crusher. In one embodiment, the blades of the conventional shredder are formed with a large area to prevent the blades from being easily worn due to a constant contact area with each other, but the SSD shredder according to the disclosed technique has the same edge of each blade And the part that touches the SSD is close to the non-plane point, so that the load on the motor is relatively reduced. Therefore, it is possible to obtain an effect that the service life is prolonged as the motor load is reduced, and it is possible to prevent the data from leaking by surely crushing the SSD.

The driving unit 150 transmits driving power to the first roller 130 and the second roller 140. The driving unit 150 receives power from the outside and transmits the power to the two rollers to drive the first roller 130 and the second roller 140 in opposite directions. In one embodiment, the driving unit 150 includes a motor 150a and can rotate the first roller 130 and the second roller 140 in opposite directions using the motor 150a.

Although the SSD shredder having a curved crushed surface according to an embodiment of the disclosed technology has been described with reference to the embodiments shown in the drawings for the sake of understanding, it is merely an example, and those skilled in the art It will be understood that various modifications and equivalent embodiments are possible. Accordingly, the true scope of protection of the disclosed technology should be determined by the appended claims.
