DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

Figure 1 shows a razor according to one embodiment of the present invention. Specifically, Fig. 1 (a) shows a front view of the razor, and Fig. 1 (b) shows a rear view of the razor.

Referring to FIG. 1, a razor 100 according to one embodiment of the present invention includes a handle 10, a head 20, a blade cartridge 30, a lid 40, an angle adjusting lever 50, An opening 60, and an elastic support 70. As shown in Fig.

One end of the handle 10 is directly or indirectly connected to the head 20 and may include a grip (not shown). In this case, the grip portion can be implemented in various forms such as a concavo-convex shape formed on the surface thereof, thereby facilitating the user's gripping and use of the shaver 100.

The head portion 20 is directly or indirectly connected to one end of the handle portion 10 so that the space in which the blade cartridge 30, the lid portion 40, the angle adjusting lever 50 and the opening portion 60 are formed . In particular, the head portion 20 can be realized such that the blade cartridge 50 and the blade cartridge 30 disposed on the front surface of the head portion 20 independently flow with the head portion 20. [ As described in more detail below, the blade unit 30 rotates independently of the head unit 20. Unlike the conventional art in which the head unit itself rotates, in the present invention, the head unit 20 So that it is possible to provide a familiar feeling to the users who used the conventional vertical razor. Further, by fixing the head portion 20 so as not to rotate, force can be easily transmitted in the direction of the knob portion 10, there is no force to disperse in the other direction, and a proper force for shaving can be sufficiently adjusted and transmitted .

The blade cartridge 30 may be disposed on the front side of the head portion 20 as a set of at least one blade for cutting hair. The blade cartridge 30 can be rotated independently of the head portion 20, and the angle of rotation can be adjusted through the angle adjusting lever 50. The cutting force is increased by about 1% every time the angle of the razor blade is increased by 1 DEG, the cutting force of the razor is raised by adjusting the rotation angle of the blade cartridge 30, It is possible to increase the shaving effect by adjusting the rotation angle of the shaft 30. In accordance with an embodiment, the blade cartridge 30 may be disposed obliquely to improve the cutting force of the blade. According to the embodiment, the blade cartridge 30 may be configured to be detachable from the head portion 20.

The lid portion 40 can be coupled to the head portion 20 at one end and to the head cartridge 20 at the opposite end. This allows the lid portion 40 to interlock with the rotation of the blade cartridge 30 when the blade cartridge 30 rotates. In particular, the lid portion 40 is made of a flexible material such as silicone or the like, so that the lid portion 40 interlocked with the rotation of the blade cartridge 30 can be easily extended and contracted. That is, when the cartridge 30 rotates, one area of the lid 40 coupled with the blade cartridge 30 is stretched and another area is contracted so that the head 30, which may occur due to rotation of the blade cartridge 30, It is possible to prevent the skin of the user from being irritated by the exposed surface or scarring the skin.

The angle adjusting lever 50 is located on the back surface of the head portion 20 and can rotate the blade cartridge 30 and adjust the rotation angle of the blade cartridge 30 during rotation. The adjustment of the rotation angle of the blade cartridge 30 may be performed by a method of rotating the blade cartridge 30 at a discontinuous angle (for example, a method of rotating the blade cartridge by angles of 5 °, 10 °, and 15 °) Or by a method of rotating the blade cartridge 30 at an angle (for example, a method of rotating within an angular range of 0 to 45 degrees, etc.). The angle adjusting lever 50 may be embodied in various shapes according to the embodiment to which the present invention is applied. For example, the angle control lever may be implemented in the form of a cog wheel to facilitate the user's operation. Depending on the embodiment, the angle-regulating lever 50 may be coupled to the pivot support to allow the flow of the blade cartridge 30 and lid 40, as will be described in more detail in Figures 3 (b) and 3 (c) It can be facilitated.

At least one opening portion 60 may be formed on the back surface of the head portion 20. [ That is, even if contaminants are introduced into the head portion 20 through the exposed surfaces of the blade cartridge 30 or the head portion 20, they can flow out through the opening portion 60 to maintain the cleanliness of the shaver. 1 shows a rectangular opening 60, which is exemplary, and various types of openings 60 may be implemented in accordance with an embodiment to which the present invention is applied.

The resilient supporting portion 70 is located between the head portion 20 and the grip portion 10 and mitigates an impact generated between the head portion 20 and the grip portion 10 so that an elastic force can be applied. The face of the person is made of various bends and it may be difficult to transmit force appropriately from the handle 10 to the head 20 or to make the head 20 come into close contact with the shaved area. However, according to the elastic supporting portion 70, the head portion 20 can perform at least one elastic movement of the front and back elastic movement, the right and left elastic movement and the vertical elastic movement about the grip 10 according to the user's operation So that an appropriate force for shaving can be transmitted through it, and the head 20 can be closely contacted to the shaving area to improve the shaving effect.

In one embodiment, the razor 100 may include a rotating portion (not shown) for rotating the blade cartridge 30. At this time, the rotation angle of the rotary part may be limited to a range (for example, 0 to 3 degrees) in which the cutting force can be improved without giving inconvenience to the user. In this manner, the rotating portion causes the blade cartridge 30 to reciprocally rotate within a fine range, and by periodically and continuously changing the blade angle, it is possible to prevent the user's skin from being damaged, . More specifically, the rotation unit may include a rotation motor that generates a rotation motion, a rotation control unit that controls the rotation motion, a power supply unit that supplies power to the rotation motor, and the like. However, Various configurations known to those of ordinary skill in the art may be employed in accordance with applicable embodiments.

In one embodiment, the razor 100 may further include a head portion 20 and a vibrating portion (not shown) capable of vibrating the blade cartridge 30 disposed in the head portion 20. As a result, not only the force applied by the user to the razor 100 but also the vibration of the vibrating portion can be used to cut the hair, thus raising the shaving effect. Particularly, even if vibration is generated by the vibrating part, the elastic supporting part 70 can prevent the vibration of the head part 20 from being transmitted to the grip part 10. [ As a result, it is possible to prevent the inconvenience of use that may be caused by the hand-transmitted vibration of the vibrating portion, thereby providing a shaving effect and a comfort simultaneously. More specifically, the vibrating unit may include a vibration motor that generates vibration, a vibration control unit that controls vibration, a power supply unit that supplies power to the vibration motor, and the like. However, the configuration of such a vibration unit is merely an example, Various configurations known to those of ordinary skill in the art, depending on the embodiment, may be employed.
