In addition to the movement of the washing water in the vertical direction between the two, it is also possible to move the washing water in the front-rear direction between the upper spacers (30a) and the front-rear direction between the lower spacers (30b).

The upper spacer 30a and the lower spacer 30b of FIG. 12 are connected to each other by a connection part 37 to form a single body, and grooves are formed at a predetermined width and depth around the connection part 37. Accordingly, the edge portion of the circumference of the hole 29 'provided in the support portion 16 of the outer blade 20B of FIG. 11 is inserted into the groove around the connecting portion 37. As shown in FIG. In addition, one fastening hole 39 penetrating one end portion of the upper spacer 30a and the lower spacer 30b in the vertical direction is formed, and the fastening rod of the base portion 40B is formed in the fastening hole 39. 41, the base part 40B and the cover 50 may be fastened. When the groove is formed around the connection portion 37 as described above, the groove may be formed around the connection portion 37 or the groove may be formed only on a portion of the connection portion 37.

The spacer as shown in FIG. 12 may be installed in the double-edged blade 20A 'of FIG. 7 as shown in FIG. 6 in such a manner that the spacer as shown in FIG. 12 is installed in the outer blade 20B of FIG. 11.

FIG. 13 illustrates a state in which portions are cut in the outer blade of FIG. 10 and the upper and lower spacers installed above and below.

FIG. 14 illustrates a partially cut outer blade of FIG. 13 with the upper spacer 30a and the lower spacer 30b removed.

FIG. 15 illustrates the upper spacers and the lower spacers partially cut and the upper spacers 30a and the lower spacer 30b in an intact state with the outer blades partially cut in FIG. 13 removed.

Meanwhile, the heights of the upper spacers 30a and the lower spacers 30b are preferably the same, but are not necessarily limited thereto.

FIG. 16 separately illustrates an example of a structure of a spacer installed between each of the razor blades as in the assembly view of FIG. 5.

In FIG. 16, two or more individual spacers 30 ′ having a narrow width in front and rear directions are connected by one elongated connecting rod 31 to form a single body. Preferably, the individual spacers 30 'are inclined by a predetermined angle (A4, A4') from the top surface, but are not necessarily limited thereto.

Compared with the case in which the individual spacers 30 'are not individually connected by the connecting rods, the structures in which the individual spacers 30' are connected by the connecting rods 31 simplify the assembly process. It can reduce the production cost.

FIG. 17 is a partial cross-sectional view of the individual spacers 30 ′ and the connecting rod 31 integrally connected thereto in FIG. 16.

FIG. 18 illustrates a state in which two or more individual spacers 30 'are connected to each other by one connecting rod 31 which is elongated and elongated as shown in FIG. 16 on the double-edged blade 20A as shown in FIG. It is possible to move the washing water in the up and down directions (D1, D2) of the left and right of the communication port 28 and the connecting rod 31 of the).

FIG. 19 illustrates a state in which two or more individual spacers 30 'are connected and installed by one elongated connecting rod 31, as shown in FIG. 16, on the outer blade 20B1 as shown in FIG. 9, the outer blade 20B1. It is possible to move the washing water in the right and left directions (D1, D2) of the right and left communication ports 28 'and the connecting rod 31.

On the other hand, the main function and role of the connecting rod 31 is to reduce the production cost by simplifying the assembly process by connecting two or more individual spacers 30 '. However, as shown in FIG. 18 or FIG. 19, the communication ports provided on the double-edged blade or the outer bladed blades, or the one-sided communication ports, and the upper and lower directions of both the left and right sides of the connecting rod 31 (D1) and (D2) In order to facilitate the movement of the washing water, the area of the communication holes of the razor blades provided on the left and right sides of the connecting rod 31 in order to facilitate the movement of the washing water and the discharge of the dirt during or after the use of the shaver. It is necessary to secure as wide as possible. Therefore, in order to secure the maximum area of the communication holes of the blades provided on both the left and right sides of the connecting rod 31 as described above, the width W2 of the connecting rod 31 is the connecting rod 31 when the shaver is assembled. It is preferable to narrow the width W2 of the connecting rod 31 as much as possible so long as the assembly is not difficult due to bending, breaking, or the like. Therefore, the width of the connecting rod 31 is preferably selected and determined within the range of 0.01 to 3 mm, and more preferably, the width of the connecting rod 31 is selected and determined within the range of 0.01 to 2 mm. Most preferably, the width of the connecting rod 31 is selected and determined within a range of 0.01 to 1 mm.

20 is a view showing the appearance and structure of the base portion 40B of the head separately in one embodiment of the double-sided shaver according to the present invention. The base portion 40B of FIG. 21 is provided with one or more fastening rods 41, and one or more ridges 42 for maintaining the distance between the base portion and the razor blade are formed. In addition, the base portion 40B is provided with one or more communication holes 48, so that the washing water can be moved in the vertical direction (D1, D2) through the communication hole 48 as shown in FIG. do.

Accordingly, the fastening rods 41 of the base portion 40B penetrate the fastening holes provided in the razor blade and the spacers, and then the ends of the fastening rods 41 protrude above the fastening holes of the lid 50. The end of the protruding fastening rod 41 is coupled by being like a rivet head. As described above, instead of the fastening rods 41 installed on the base 40B and the fastening holes provided in the cover, the fastening bars may be installed below the bottom of the cover 40B and the fastening holes may be provided in the base 40B. have.

On the other hand, the height (H4) of the front surface (43a) of the base portion 40B has a lower structure than the height (H5) of the rear surface (43b), such a structure is the base portion 43 of both sides of the head When the number of blades and their cutting edges are provided on the head surface to which the front surface 43a of the substrate belongs, the base portion 40B is proportional to the distance between the blades and the cutting edges. The gap between the top and bottom of the front (43a) of the blade and its cutting edge is maintained to be somewhat large. The difference between the height H4 of the front surface 43a of the base portion 40B and the height H5 of the rear surface 43b is preferably selected within a range of 0.5 to 3 m, but is not necessarily limited thereto. none.

On the other hand, in the wet multi-blade shaver, the larger the spacing between the blades installed in the razor head, the easier the discharge of dirt, such as beard scum, and the higher the cleaning efficiency. The greater the likelihood of injuries such as cuts of the skin due to the cutting edges when shaving is also increased.

In addition, when the blade is erected at an angle from the skin as shown in FIG. 25 or FIG. 29 as compared to when the blades are laid parallel to the surface of the skin as shown in FIGS. 26 to 28, the cutting edge may cut the base of the beard deeper into the skin. This makes it possible to shave more neatly, but if the blades are erected at an angle from the skin, the likelihood of getting cuts, such as cuts of the skin by the cutting edge, is also increased.

Thus, the likelihood of injuring skin cuts or the like during shaving is highest when the spacing between the blades is wider and the blades are at an angle from the skin.

The head 303 of FIG. 22 has a larger number of blades 22a1, 22b2, 22a3, 22b4, 22a5 and cutting edges on one side of the head, on both sides of the head. And the spacing between the blades 22a1, 22b2, 22a3, 22b4, 22a5 is narrower, while fewer blades on the other side of the head (22a1), (22a3), (22a5) and its cutting edges, and also the spacing between the fewer blades (22a1) (22a3) (22a5) It is wide.

Therefore, when shaving using a double-sided shaver equipped with a head 303 as shown in Figure 21, blades (22a1), ( When shaving using the cutting edges 22a3) and 22a5), the blades 22a1, 22b2, (the other side of the head, i.e., the head face of the side of which the gap between the blades is narrower) 22a3), (22b4), (22a5)) than the shaving using the cutting edge, it is easier to discharge the dirt, such as beard scum, and the cleaning efficiency is higher, but also more likely to injure skin cuts do.

In addition, since the inclination angles of the blades provided on both sides of the head 303 are smaller than the inclination angles of the

blades

52a and 52b of the cover, as shown in FIG. 25 or 29 when shaving.

Since the blade is erected from the skin at an angle, the cutting edge cuts the base of the beard deeper into the skin, resulting in a cleaner shave, but more likely to injure skin cuts and the like. do. In particular, when shaving using the cutting edges of the head surface having a larger spacing between the blades, both sides of the head are more likely to be injured, such as skin cuts.

The head 304 of FIG. 23 has blades 22a1 ', 22a3', 22a5 on the side of the head on which the fewer blades of both sides of the head are installed, compared to the head 303 of FIG. Angle of inclination is greater than the inclination angle of a larger number of blades 22a1, 22b2, 22a3, 22b4, 22a5 installed on the opposite side of the head or The inclination angles of (22a1 '), 22a3', and 22a5 'are equal to the inclination angle of the blade 52a of the head. Thus, as in the case of the head 304 of FIG. 2, when the inclination angles of the blades 22a1 ', 22a3', and 22a5 'are equal to the inclination angle of the blade 52a of the head, That is, when the surface of the blade 52a and the surface of the blades are parallel, even if the spacing between the blades (22a1 ', 22a3', 22a5 ') is slightly wider, as shown in FIG. As shown in FIG. 30, the surfaces of the blades 22a1 ', 22a3', and 22a5 'are parallel to the surface of the skin, thereby significantly reducing injuries such as cuts of the skin due to the cutting edges during shaving. have. However, the blades 22a1 ', 22a3', 22a5 'have their cutting edges polished at both sides. Thus, as described above, the inclination angles of the blades 22a1 ', 22a3', and 22a5 'are equal to the inclination angle of the blade 52a of the head, and the blades 22a1', ( When the cutting edge portions 22a3 ') and 22a5') are polished at both sides, as shown in FIG. 26 or 30, the cutting edge portions are not easily contacted with the surface of the skin and are likely to be spaced apart at a predetermined distance, thereby shaving the beard during shaving. Poor cutting forces on the field can make efficient shaving difficult and uncomfortable to use. This phenomenon is particularly pronounced when the beard 11 is laid down or collapsed at an angle as shown in FIG. 30.

The head 305 of FIG. 24 is similar to the head 304 of FIG. 23, but the blades 22a1 ", 22a3", 22a5 "of the head 305 of FIG. 24 have their cutting edges. Polishing is done only on the inner side F1 as in Fig. 27 or 31. Thus, using the cutting edges of the blades 22a1 ", 22a3 ", 22a5 " When shaving, even if the spacing between the blades 22a1 ", 22a3", and 22a5 "is slightly wider, injuries such as cuts of the skin due to the cutting edges can be significantly reduced during shaving. At the same time also the cutting edges of the blades 22a1 ", 22a3 ", 22a5 ", as in FIG. 27 or 31, can be brought into contact with the skin surface to maintain a significant level of cutting force. Of course, when shaving using the cutting edges of the head surface with blades 22a1 ", 22a3 ", 22a5 " among the two sides of the head 305 of FIG. The shaving force is lowered than shaving using the cutting edges of the blades 22a1, 22b2, 22a3, 22b4, and 22a5 provided on one side. Since the blades 22a1 ", 22a3", and 22a5 "of the both sides of the head 305 have a larger distance, the cutting edges of the head surface of the side of the head having excellent discharge and cleaning power can be obtained. After shaving using the first shaving, the blades on the other side of the head 305, i.e. more compactly spaced and with larger inclination angles (22a1), (22b2), (22a3) and (22b4) (22a5)), using the cutting edges of the head face to finish shaving on stubble stub remaining after the initial shaving, more efficient It will be able to easily shave.

25 or 29 shows that the blade 22a of the double-edged blade 20A-1 is erected at an angle with respect to the skin surface 12 so that the beard 11 rises straight above the surface of the skin 12 as in FIG. In addition to the case where it is raised and also when the beard 11 is somewhat collapsed as shown in FIG. 29, the cutting edge 21a of the blade 22a can efficiently cut the base of the beard 11, thereby making it more neat. You can shave. However, when shaving in a state where the blade 22a is set at an angle with respect to the skin surface 12 as described above, as in FIG. 26 to FIG. 28, the possibility of injury such as cuts of the skin is more likely than when the blade is lying parallel to the skin surface. This becomes higher, and the likelihood of such cuts increases as the spacing of the blades erected at an angle to the skin surface as described above.

26-28 and the double-edged blades of FIGS. 30-32 have a smaller angle A3 'formed by one blade with the blade member than an angle A3 with one blade made in contact with the blade member. It is. And as described above, the blades forming a small angle (A3 ') with the blade member is laid parallel to the skin surface 12, in such a state, even if the spacing between the blades slightly wider when shaving The likelihood of injury such as cuts in the skin is significantly reduced

However, since the blade 22A-2 of the double-edged blade 20A-2 of FIG. 26 is polished on both sides of the cutting edge 21a-2, the cutting edge 21a-2 becomes the skin 12. By being not in proper contact with the surface of the and spaced apart, the cutting force on the beards at the time of shaving may be reduced, making efficient shaving difficult and inconvenient to use. This phenomenon becomes more pronounced especially when the beard 11 falls down or lies at an angle as shown in FIG. 30.

Although the blades 22a-3 of the double-edged blade 20A-3 in FIG. 27 are laid parallel to the surface of the skin 12, the cutting of the cutting edge 21a-3 is performed only at the inner side F1. This allows the cutting edge 21a-3 to be in contact with the surface of the skin 12 so that the beard 11 rises straight above the surface of the skin 12 as in FIG. 26 as well as in FIG. 31. Even when the beard 11 is somewhat collapsed, a considerable cutting force can be maintained.

The blades 22a-4 of the double-edged blade 20A-4 in Fig. 28 are polished only on the outside of the cutting edge 21a-4, so that the cutting edge 21a-4 is properly aligned with the skin surface 12. By being spaced apart without contact, the cutting force on the beard 11 at the time of shaving is reduced, making efficient shaving difficult and inconvenient to use. This phenomenon is particularly pronounced when the beard 11 is laid down or collapsed at an angle as shown in FIG. 32.

On the other hand, the length of the blade on the side of the head face with fewer cutting edges is slightly longer than the length of the blade on the opposite head side, whereby the spacing between the blades can be adjusted.
