Description

  The present invention is an electric razor having a cutting structure for rough shaving of long hairs and comb hairs, and in particular, an electric body provided with combs for promoting raising and hair introduction on the outer surface of the outer blade of the cutting structure Related to razor.

  In the cutting structure for rough shaving, it is known in, for example, Patent Document 1 and Patent Document 2 to provide a comb body on the outer surface of the outer blade. In the former, a pair of front and rear slit rows is formed on the upper surface of the outer blade, and a comb body is disposed along one side of the groove formed in a recess between the slit rows. A group of comb teeth is formed on the comb body at regular intervals along the longitudinal direction of the groove.

  In the latter, a comb body is externally attached to the outer surface of the outer blade. The comb body is configured by providing a group of inverted L-shaped comb teeth in a front-rear facing manner at both upper corners of a U-shaped comb frame that opens downward. In a state in which the comb frame is externally fitted to the outer blade, a group of comb teeth covers the upper corners of the outer blade, so that the skin surface can be moved away from the outer blade by the thickness of the comb teeth.

  Thus, according to the cutting structure provided with the comb body, the long hair can be introduced and guided to the cutting edge portion of the outer blade with a group of comb teeth, or can be roughly shaved while raising the comb hair. According to the cutting structure of Patent Document 2, the skin surface is kept away from the outer blade by the thickness of the comb teeth, and the skin surface is prevented from directly touching the outer blade. It can be prevented from being depressed and damaged.

JP 10-323463 A (paragraph number 0014, FIG. 1) Japanese Patent Laid-Open No. 9-24167 (paragraph number 0037, FIG. 4)

  According to the above-described cutting structure, it is possible to introduce and guide long hairs to the outer blade with a group of comb teeth or to raise comb hairs. However, the comb body is installed at a position that is the same as or lower than the top surface of the main blade, and the width of the front and rear of the outer blade is small. Difficult to do. By the way, in this type of cutting structure in which the outer blade is composed of a slit blade, by reducing the slit width of the outer blade, the skin surface is prevented from falling into the slit, but the slit width of the outer blade becomes smaller. The hair can not be effectively introduced into the slit. Conversely, if the slit width is increased, hair can be effectively introduced into the slit, but when the outer blade is pressed strongly against the skin surface, part of the skin protrudes into the slit and is damaged.

  In this regard, according to the cutting structure of Patent Document 2, it is possible to prevent the skin surface from protruding into the slit (cutting blade portion) of the outer blade by fitting the comb frame to the outer blade. However, since a group of comb teeth is provided in an inverted L shape only at both upper corners of the comb frame, it is inevitable that a gap is generated between the front and rear comb groups. If there is a gap in the center of the upper surface of the comb body in this way, the hair passing through the gap portion cannot be captured and guided, and there is a possibility that the hair that has been raised by the comb teeth will fall down to the skin surface again. Furthermore, since the slit of the outer blade is exposed at the gap portion, when the outer blade is strongly pressed against the skin surface, the skin surface cannot be avoided from coming into contact with the skin surface, and the skin may be damaged.

  The object of the present invention is a comb body provided on the outer surface of the outer blade, which can reliably capture and guide long hairs and comb hairs, and ensures the introduction of hair into the cutting edge portion of the outer blade, thereby effecting rough shaving of the beard. The purpose is to provide an electric razor that can be used automatically. The object of the present invention is to reliably prevent the skin surface from protruding into the slit even when the outer blade has a wide slit, and even when the outer blade is strongly pressed against the skin surface. An object of the present invention is to provide an electric razor that can reliably eliminate surface scratches.

  The electric razor of the present invention is provided with a cutting structure 12 for rough shaving of long hairs and comb hairs in the razor head 5. The cutting structure 12 includes an outer blade 44 disposed on the outer surface of the razor head 5, an inner blade 45 driven to slide along the inner surface of the outer blade 45, and a comb body mounted on the outer surface of the outer blade 44. 48. The comb body 48 has a base frame 66 that fits externally on the outer blade 44, and a group of comb teeth 67 and whisker introduction grooves 68 that capture the whiskers are alternately formed on the upper portion of the base frame 66. The upper outer surface of the cover is covered with comb teeth 67.

  In FIG. 5, the outer blade 44 is constituted by a slit blade in which a group of bead introduction slits 50 and blade ribs 51 that divide adjacent slits 50 are alternately formed. A blade 52 is formed.

  A whisker introduction groove 68 is formed between the comb teeth 67 of the comb body 48, and as shown in FIG. 8, the formation interval between the slit 50 of the outer blade 44 and the whisker introduction groove 68 of the comb body 48, and the opening. The comb body 48 can be attached to the outer blade 44 such that the opening positions of both 50 and 68 coincide with each other with the interval set equal.

  A cutting structure 12 for rough shaving and a main blade 11 for cutting the beard after rough shaving are arranged adjacent to the razor head 5, and the upper surface of the comb body 48 is seen from the top surface of the main blade 11 as shown in FIG. It can project upward.

  The main blade 11 and the cutting structure 12 for rough shaving are supported so that they can float up and down, respectively, and the main blade 11 and the cutting structure 12 for rough shaving sink to the lower limit position as shown in FIG. In this state, the upper surface of the comb body 48 protrudes upward from the top surface of the main blade 11.

  The spring force of the spring 47 that pushes and biases the cutting structure 12 for rough shaving can be set smaller than the spring force of the spring 40 that pushes and biases the main blade 11.

  A tapered introduction end 72 is formed around the upper edge of the comb teeth 67, and the leading end angle θ of the introduction end 72 can be made acute as shown in FIGS. A plurality of raised protrusions 73 for pressing the skin surface can be formed on the outer surface of the comb teeth 67 as shown in FIG.

  The base frame 66 of the comb body 48 includes end frames 70 at both ends in the longitudinal direction and a pair of front and rear mounting frames 71 that connect the end frames 70 to each other. The whisker introduction groove 68 formed between the adjacent comb teeth 67 can be opened at the front and rear surfaces of the comb body 48.

  The groove lower end positions before and after the whisker introduction groove 68 formed in the comb body 48 can be positioned below the slit lower end positions before and after the slit 50 formed in the outer blade 44.

  In the present invention, the comb body 48 is mounted on the outer surface of the outer blade 44 for rough shaving, and the upper outer surface of the outer blade 44 is covered with the comb teeth 67 provided on the upper portion thereof, so that the long hair and the comb hair that have fallen into the skin surface are combed. The teeth 67 can be reliably raked up and guided to the whisker introduction groove 68. Therefore, the hair can be surely introduced into the cutting edge 52 as compared with the conventional example, and the shaving of the beard can be effectively performed. In addition, since the upper outer surface of the outer blade 44 is covered with the comb teeth 67, the comb body 48 ensures that the skin surface does not protrude into the slit 50 even if the outer blade 44 has a wide slit 50. Even when the outer blade 44 is strongly pressed against the skin surface, it is possible to reliably eliminate the damage on the skin surface. If the slit 50 of the outer blade 44 is formed wide, the whiskers can be introduced into the slit 50 more reliably and rough shaving can be performed more effectively.

  When the outer blade 44 is constituted by a slit blade in which a group of bead introduction slits 50 and blade ribs 51 are alternately formed, the direction of the slit 50 of the outer blade 44 and the beard introduction groove of the comb body 48 are formed. The whisker trapped by the comb teeth 67 can be surely and smoothly introduced into the slit 50 by matching with the direction 68, and the shaving of the whiskers can be performed quickly and efficiently.

  The formation interval between the slit 50 of the outer blade 44 and the whisker introduction groove 68 of the comb body 48 and the opening interval are set to be the same, and the comb body 48 is arranged so that the opening positions of both 50 and 68 coincide. 44, since a part of the inner surface of the whisker introduction groove 68 can be prevented from being blocked by the blade rib 51 of the outer blade 44, it is captured by the comb teeth 67 and introduced into the beard introduction groove 68. Most of the whiskers can be taken into the slit 50 to effectively shave the whiskers.

  When the upper surface of the comb body 48 protrudes upward from the top surface of the main blade 11 disposed adjacent to the cutting structure 12, the comb teeth 67 are brought into contact with the skin surface first, thereby combing long hairs and comb hairs that have fallen into the skin surface. The teeth 67 can be effectively raked up, and the shaving with the center blade 12 can be effectively performed accordingly.

  When the upper surface of the comb body 48 protrudes upward from the top surface of the main blade 11 in a state where the main blade 11 and the cutting structure 12 for rough shaving are each submerged to the lower limit position, the skin surface is strongly pressed. Even in the state, the comb teeth 67 are brought into contact with the skin surface first, and the comb hairs and long hairs that have fallen into the skin surface are scooped up with the comb teeth 67, so that the rough shaving with the center blade 12 can be performed more reliably.

  As described above, when the upper surface of the comb body 48 protrudes upward from the top surface of the main blade 11, the comb body 48 always contacts the skin surface more than the main blade 11. In addition, the cutting structure 12 having a smaller front-rear width than the main blade 11 is likely to receive a larger surface pressure than the main blade 11 due to the smaller contact area. In order to cope with such a situation, the spring force of the spring 47 that pushes up and biases the cutting structure 12 for rough shaving is set smaller than the spring force of the spring 40 that pushes up and biases the main blade 11 to cut the cutting structure. 12 is submerged with a smaller force, making the skin feel softer.

  If the leading edge 72 is formed in a tapered shape around the upper edge of the comb teeth 67 and the leading edge angle θ is sharp, long hairs and comb hairs that adhere closely to the skin surface are scooped up at the leading edge 72. Therefore, it is possible to shave while introducing the beard into the beard introduction groove 68 more effectively.

  When a plurality of raised protrusions 73 are formed on the outer surface of the comb teeth 67, it is possible to stand a beard that has fallen on the skin surface by pressing the skin surface with the raised protrusions 73 and pulling the skin. The beard cutting by the blade 11 can be performed more effectively.

  When the whisker introduction groove 68 formed between the comb teeth 67 of the comb body 48 is opened on the front and rear surfaces of the comb body 48, the whisker is introduced into the whisker introduction groove 68 from either side of the front and rear surfaces, The cutting opportunity is increased, and the beard cutting at the time of rough shaving can be performed efficiently. In particular, when the cutting structure 12 is disposed between the pair of front and rear main blades 11, the beard immediately after shaving with the cutting structure 12 can be cut with the front and rear main blades 11, so that the beard cutting is effectively performed. Yes.

  When the groove lower end positions before and after the whisker introduction groove 68 are located below the slit lower end positions before and after the slit 50, all the cutting blades 52 on the outer blade 44 side are exposed to the beard introduction groove 68, and the whisker introduction groove 68 is exposed. The chance of contact between the whisker introduced into the introduction groove 68 and the cutting blade 52 can be increased, and the beard cutting can be performed more effectively by that amount. In particular, when the slit 50 and the opening position of the beard introduction groove 68 coincide with each other, most of the beard introduced into the beard introduction groove 68 can be guided and cut into the slit 50, so that the beard cutting is effectively performed. Yes.

The main blade 11 is provided for the purpose of shaving a relatively short beard, while the center blade 12 is provided for rough shaving of long hairs and comb hairs.

  The main blade 11 includes an outer blade holder 13, a pair of outer blade cassettes 14 supported by the outer blade holder 13 so as to float up and down, an inner blade unit 15 that is slidably driven along the inner surface of the outer blade cassette 14, and the like. including.

  In FIG. 4, the outer blade holder 13 includes an inner case 18 and an outer case 19 that supports the inner case 18. A pair of front and rear outer blade cassettes 14 and a center blade 12 are assembled to the inner case 18. ing.

  The inner case 18 is a rectangular frame-shaped plastic molded product having an open top and bottom surface, and a reinforcing frame 21 is integrally provided at the front and rear center of the lower opening surface, and a through-hole 22 for a drive shaft 41 to be described later is provided at the left and right center. Is formed in a vertically penetrating manner. A spring arm 23 is integrally formed on the front and rear surfaces of the reinforcing frame 21 to move and urge the outer blade cassette 14 downward.

  The outer case 19 is a square frame-shaped plastic molded product whose upper and lower surfaces are open. By inserting the inner case 18 into the inner surface of the outer case 19 from above and engaging the protrusions provided on the side walls of the cases 18 and 19 with the recesses, the cases 18 and 19 can be integrated. The outer case 19 is externally fitted and attached to the head case 16 of the razor head 5, and the attached state can be maintained by engaging and capturing with lock claws 25 incorporated on the left and right sides of the head case 16.

  The lock claw 25 is formed integrally with the lock release button 26, and is locked by a compression coil type lock spring 27 (see FIG. 3) to engage with a lock recess 28 provided on the inner surface of the outer case 19. To do. When the lock release button 26 is pushed against the urging force of the lock spring 27, the engagement state between the lock claw 25 and the lock recess 28 can be released, so that the outer blade holder 13 can be removed from the head case 16.

  The outer blade cassette 14 is configured by retaining an outer blade 31 formed of a sheet-like mesh blade in an arch shape with an outer blade frame 32. The outer blade 31 is formed by an etching method or an electroforming method. The outer blade frame 32 is guided and supported by the inner case 13 so as to be movable up and down, but cannot be pulled out.

  The inner blade unit 15 includes an inner blade 34 formed as a slit blade and an inner blade frame 35 that supports the inner blade 34. The inner blade 34 is formed by pressing a sheet-like inner blade blank formed by an etching method, and is different from the outer blade 31 in that the arch shape can be self-held. A passive piece 38 that is engaged and connected to the drive shaft 37 of the vibrator 36 is integrally provided at a lower portion of the inner blade frame 35.

  The inner blade unit 15 is pushed up and biased by a compression coil spring 40 interposed between the drive shaft 37 and the passive piece 37. The biasing force of the spring 40 is set sufficiently larger than the biasing force of the previous spring arm 23. Therefore, the inner blade 34 can be kept in close contact with the inner surface of the outer blade 31 even though the inner blade unit 15 is supported by the drive shaft 37 so as to be vertically movable and can be tilted left and right.

  The vibrator 36 converts the rotational power of the motor 8 into a reciprocating operation, and then transmits it to the inner blade unit 15 via the drive shaft 37. As shown in FIG. 1, the drive shaft 37 is provided corresponding to each inner blade unit 15, but another drive piece 41 for driving the inner center blade 45 is fixed to one of the drive shafts 37. The drive piece 41 is engaged and connected to the passive piece 42 of the inner center blade 45 in the through hole 22 provided in the reinforcing frame 21 of the inner case 18.

  5 and 6, the center blade 12 includes an outer center blade (outer blade) 44, an inner center blade (inner blade) 45 that is slidably driven along the inner surface of the outer center blade 44 in the longitudinal direction, A pair of left and right blade receiving frames 46 that support the center blades 44 and 45, a pair of left and right springs 47 that push up and bias the inner center blade 45, and a comb body 48 that is externally fitted to the outer center blade 44 are included.

  The outer center blade 44 is formed in an inverted U-shaped cross section by pressing a blade blank formed by etching using a metal sheet as a raw material. On the upper curved surface of the outer center blade 44, slits 50 for introducing beards and blade ribs 51 are alternately formed. A cutting blade 52 for cutting the beard is formed on the inner periphery of the blade rib 51 facing each slit 50.

  The inner center blade 45 is similarly formed using the same material as the outer center blade 44, and slits 54 and blade ribs 55 are alternately formed on the upper curved surface thereof. The cutting blade 56 for cutting the whiskers is formed on the outer peripheral edge of the blade rib 55. A passive piece 42 that engages with the drive piece 41 is fixed to the left and right central portions of the inner surface of the inner center blade 45.

  In FIG. 5, the blade receiving frame 46 is integrally provided with an L-shaped mounting seat 58, a guide portion 59 formed on the upper surface of the mounting seat 58, and an engagement leg 60 formed on the outer surface of the mounting seat 58. It consists of a plastic molded product. With the guide portions 59 of the left and right blade receiving frames 46 inserted and attached to the inner surfaces of both ends of the inner center blade 45, the outer center blade 44 is put on the mounting seat 58 from above, and the fixing pin 61 provided on the mounting seat 58 is melt-deformed. By doing so, the outer center blade 44 and the left and right blade receiving frames 46 can be integrated. The inner center blade 45 in this state is guided and supported by the guide portion 59 of the blade receiving frame 46 so as to be slidable in the left and right directions.

  The blade receiving frame 46 is inserted into the front and rear central portions of the inner case 18 from above, and the engaging legs 60 are engaged with the guide grooves 63 provided in both side walls of the inner case 18 as shown in FIG. Is supported by the inner case 18 so as to float up and down. In order to bring the inner center blade 45 into close contact with the outer center blade 44 and simultaneously push up and bias the entire center blade 12, there are two compression coil shapes between the reinforcing frame 21 of the inner case 18 and the passive piece 42. The spring 47 is arranged.

  The comb body 48 is a plastic molded article having a flat cross-section with a flat top surface, and has a base frame 66 that fits on the top surface of the outer center blade 44, and comb teeth 67 that capture the whiskers on the top of the base frame 66. The whisker introduction grooves 68 are alternately formed. The formation interval and the opening interval of the whisker introduction groove 68 are set to be the same as the formation interval and the opening interval of the slit 50 of the outer center blade 44, and the combs are arranged so that the opening positions of both 44 and 68 coincide. The body 48 is fixed to the outer center blade 44.

  The base frame 66 is formed in a box shape that is opened downward by an end frame 70 having a U-shaped cross section provided at both ends in the longitudinal direction and a pair of front and rear mounting frames 71 that connect the end frames 70 and 70 to each other. A group of comb teeth 67 are integrally formed continuously on the upper and lower mounting frames 71 so that the whisker introduction groove 68 between the adjacent comb teeth 67 is opened at the front and rear surfaces of the comb body 48.

  The lower half portion of the mounting frame 71 has a larger front-rear width than the upper half portion. This is because a welding frame 75 described later is disposed on the inner surface of the outer center blade 44. In order to mount the comb body 48 in close contact with the outer center blade 44, the inner surface shapes of the end frame 70 and the comb teeth 67 are formed in an inverted U shape to match the outer surface shape of the outer center blade 44. .

  By forming the upper and lower portions of the comb teeth 67 with an upwardly curved surface, the tapered introduction ends 72 are formed before and after the upper edges of the comb teeth 67. The introduction end 72 is formed so as to protrude from the front and rear wall surfaces of the base frame 66, and the tip end angle θ is an acute angle. In this embodiment, the tip angle θ is 50 degrees. As described above, when the introduction end 73 protruding from the front and rear wall surfaces of the base frame 66 and having the acute end angle θ is formed at the front and back of the upper portion of the beard introduction groove 68, the hairs and long hairs that have fallen into the skin surface are introduced. 72, and can be guided and guided into the whisker introduction groove 68. In order to improve skin contact, the leading end 72 is rounded.

  In order to perform more effective raising, a partially spherical raising protrusion 73 is provided on each of the three upper surfaces of the comb teeth 67 and the front and rear surfaces. When the surface of the comb body 48 comes into contact with the skin surface, the raised protrusions 73 push the skin surface to be tensed as shown in FIG. 8, and thereby, the comb hairs and long hairs falling on the skin surface can be erected.

  The comb body 48 is welded and fixed to the outer center blade 44. Specifically, as shown in FIG. 7, after the comb body 48 is attached to the outer center blade 44, a welding frame 75 is arranged on the inner surface of the outer center blade 44, and the welding pin 76 is attached to the base frame 66 of the comb body 48. The comb body 48 is fixed to the outer center blade 44 by melting and deforming on the outer surface. The welding pin 76 is melted and deformed in a state of penetrating the front and rear walls of the outer center blade 44 and the mounting frame 71 of the base frame 66.

  As described above, in a state where the comb body 48 is mounted and fixed to the outer center blade 44, the upper surface of the comb body 48, that is, the upper surface of the comb teeth 67 protrudes upward from the top surface of the main blade 11 as shown in FIG. ing. This is because the comb teeth 67 are made to come into contact with the skin surface, long hairs and comb hairs that have fallen into the skin surface are effectively scooped up by the comb teeth 67, and rough shaving with the center blade 12 is effectively performed.

  Further, the lower end positions of the front and rear grooves of the whisker introduction groove 68 provided in the comb body 48 are positioned lower than the lower end positions of the slits 50 formed on the outer blade 44. This exposes all of the cutting blades 52 on the outer blade 44 side to the whisker introduction groove 68, increases the chance of contact between the beard introduced into the whisker introduction groove 68 and the cutting blade 52, and effectively performs beard cutting. Because. If the groove lower end positions before and after the beard introduction groove 68 are positioned above the slit lower end positions before and after the slit 50, the beard cutting must be performed only by the cutting blade 52 exposed in the beard introduction groove 68. This is because the opportunity for cutting the beard is reduced, and it takes time to cut the beard accordingly.

  As described above, the upper surface of the comb body 48 in the normal state protrudes upward from the top surface of the main blade 12, and the main blade 11 and the center blade 12 individually float up and down to the skin surface. Maintain close contact. When the main blade 11 and the center blade 12 are pressed strongly against the skin surface at the same time, both 11 and 12 sink to the lower limit position as shown by the solid line in FIG. Protrudes upward from the top surface of the main blade 11 and contacts the skin surface first. Therefore, comb hairs and long hairs can be scooped up with comb teeth 67 while strongly pressing the skin surface, and rough shaving with the center blade 12 can be performed effectively.

  The spring force of the spring 47 that pushes up and biases the center blade 12 is set smaller than the spring force of the spring 40 that pushes up and biases the main blade 11. In order to make the skin contact soft by making the center blade 12 provided in a state of projecting from the main blade 11 and having a narrow width and a surface pressure larger than that of the main blade 11 to be submerged with a smaller force. It is. When the comb body 48 is formed of a plastic molded product as described above, the skin of the comb teeth 67 can be softened, and the color of the comb body 48 can be changed as necessary to have various appearance impressions. 5 can be obtained.

  FIG. 10 shows another embodiment of the comb body 48. Here, the mounting frame 71 of the base frame 66 is omitted, and instead, adjacent comb teeth 67 are connected by ribs 78 that bridge the front and rear center portions of the whisker introduction groove 68. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted. The comb body 48 is bonded and fixed to the outer center blade 44.

  In addition to the above-described embodiments, the present invention can also be applied to an electric razor in which the cutting structure 12 is disposed on either one of the front and back sides of one main blade 11. The outer center blade 44 may be formed of a mesh blade in addition to the slit blade. The inner center blade 45 can be formed by a group of small blades. The inner blade 34 of the main blade 11 can be formed by a rotary blade. The upper surface of the comb body 48 does not have to be flat, and may be formed of, for example, an upward convex gently curved surface. The comb body 48 can be detachably attached to the outer center blade 44.
